CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of, and priority to, U.S. Patent Application No. 17/530,053 filed on November 18, 2021, the content of which is expressly incorporated herein by reference in its entirety for any and all non-limiting purposes.

FIELD

[0002] This disclosure relates to portable container with latching systems.

BACKGROUND

[0003] Various types of containers and latching systems exist. Containers may be used for food, beverages, and other materials or items. Latching systems exist to lock the containers in a closed configuration. However, conventional containers and latching systems are often not very durable and may not be easy to use. For instance, containers may not be strong enough to hold certain items and may not be strong enough to hold items on top of the container. Additionally, some latching systems may engage when a user does not want the system engaged and in other cases may not provide a sufficient lock between for the container. In such arrangements these and other deficiencies may render the container and/or latching system virtually useless.

BRIEF SUMMARY

[0004] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. The Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

[0005] One aspect of the disclosure may relate to a container comprising: (a) a base that includes (1) a sidewall structure having at least a first side and a second side opposite the first side, the sidewall structure having a first end and a second end opposite the first end; (2) a bottom portion connected to the first end of the sidewall structure and configured to support the container on a surface; and (3) a base opening formed at the second end of the sidewall structure, where the base opening is configured to allow access to an interior void of the container formed by the sidewall structure and the bottom portion; and (b) a lid pivotally connected to the base and having a shape corresponding to a shape of the base, where the lid is configured to rotate between an open configuration that allows access to the base opening and a closed configuration that prevents access to the base opening; and (c) a latch assembly having a locked position and an unlocked position. The latch assembly may comprise: (a) a latch body pivotally connected to the lid; (b) a latch button slidably connected with the latch body, the latch button having a latch button-locking member; (c) a latch-locking arm pivotally connected to the latch body, where the latch-locking arm has an latch arm-locking member; (d) a latch button biasing member that exerts a linear force on the latch button; and (e) a latch-locking arm biasing member that exerts a rotational force on the latch-locking arm. To move the latch assembly to a locked position, the latch-locking arm engages the base and rotates against the rotational force of the latch-locking arm biasing member, and the latch button moves against the linear force of the latch button biasing member until the latch button-locking member engages the arm-locking member. Additionally, the latch button-locking member may engage the arm-locking member when the latch-locking arm is in a substantially vertical position. In the exemplary embodiment, the latch-locking arm biasing member is a torsional spring. The latch arm-locking member may include a first locking surface and a curved upper surface extending from an upper edge of the first locking surface, where the latch arm-locking member may be substantially centered along the latch-locking arm. The latch-locking arm may have a pair of engaging members arranged on each side of the arm-locking member, and each engaging member of the pair of engaging members may be spaced from the arm-locking member. In addition, each engaging member of the pair of engaging members of the latch-locking arm may have an end with a curved surface that engages a receiver positioned under a lip that extends along the first side of the base. The latch assembly may also include an interlocking pawl that is rotatably attached to the latch body and located closer to an upper edge of the latch body than a lower edge of the latch body. The interlocking pawl may include a central member with an aperture extending through the base, a first protrusion extending outward from the central member, and a second protrusion extending outward from the central member opposite the first protrusion. The first protrusion of the interlocking pawl may contact the latch button when the latch assembly is in the unlocked position to prevent the latch button from moving upwards. And the second protrusion of the interlocking pawl may have a curved outer surface that contacts the lid when the latch assembly is in the unlocked position to prevent the latch assembly from locking before the lid is in the closed configuration. The latch assembly may also include a third biasing member that exerts a second rotational force on the interlocking pawl. In some examples, the container may include a divider that extends across a lid opening of the lid, where the divider is pivotally connected to the lid. The divider may be connected to the lid with a hinge and be selectively secured to the lid on a side opposite the hinge to prevent rotational movement of the divider. The divider may also be releasably secured to the lid with a snap fit. The divider may include a plurality of elongated openings.

[0006] Other aspects of the disclosure may relate to a container comprising: (a) a base that includes: (1) a base sidewall structure having at least a first side, a second side opposite the first side, a first end, and a second end, (2) a bottom portion connected to the first end of the base sidewall structure that is configured to support the container on a surface, and (3) a base opening formed at the second end of the base sidewall structure, where the base opening being configured to allow access to a base interior void of the base formed by the base sidewall structure and the bottom portion; and (b) a lid pivotally connected to the base, where the lid includes: (1) a lid sidewall structure that has at least a first side, a second side opposite the first side, a first end, a second end opposite the first end, (2) an upper portion connected to the second end of the lid sidewall structure, (3) a lid opening formed at the first end of the lid sidewall structure the lid opening being configured to allow access to a lid interior void formed by the lid sidewall structure and the upper portion, and (4) a divider pivotally connected to an interior portion of the lid that separates the base interior void and the lid interior void; and (c) a latch assembly pivotally connected to the lid having a locked position and an unlocked position. The divider may include a front side, a rear side, a first side that includes an integrated hinge, and a second side opposite the first side, where the integrated hinge is connected to a hinge receiver of the lid. The lid may be configured to rotate between an open configuration that allows access to the base opening and a closed configuration that prevents access to the base opening. The second side of the divider may include a centrally located recess that forms a pair of tabs, where each tab of the pair of tabs includes an engagement receiver that form a friction fit with a lid engaging member that extends from an interior surface of the lid to prevent rotational movement of the divider. In some examples, the divider may also include a plurality of elongated openings that extend across a portion of the front side of the divider in a direction oriented from the first side of the divider to the second side of the divider. The latch assembly of the container may comprise: (a) a latch body pivotally connected to the lid; (b) a latch button slidably connected with the latch body, where the latch button has a latch button-locking member; (c) a latchlocking arm that is pivotally connected to the latch body, where the latch-locking arm has an arm-locking member; (d) a latch button biasing member that exerts a linear force on the latch button; and (e) a latch-locking arm biasing member that exerts a rotational force on the latch-locking arm. When the latch assembly is moved to the locked position, the latch-locking arm may engage the base and rotate against the rotational force, and the latch button may move against the linear force until the latch button-locking member engages the arm-locking member.

[0007] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. The Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

It is understood that the containers and latching assemblies may contain components made of several different materials. Additionally, the components may be formed by various forming methods. For example, metal components, may be formed by forging, molding, casting, stamping, machining, and/or other known techniques. Additionally, polymer components, such as elastomers, can be manufactured by polymer processing techniques, such as various molding and casting techniques and/or other known techniques.

[0032] The various figures in this application illustrate examples of containers and latching assemblies according to this invention. When the same reference number appears in more than one drawing, that reference number is used consistently in this specification and the drawings refer to the same or similar parts throughout.

[0033] FIGS. 1-15 depict different views of a container 100. The container 100 may include a base 110 and a lid 150 that, in some examples, may be coupled, or in some examples may be non-destructively, removably coupled, thereto. The base 110 may be a structure forming a void for containing articles, as will be discussed more fully herein. In some examples, the base 110 may be cuboidal or substantially cuboidal in shape. In other examples, the base 110 may be prismoidal or substantially prismoidal (e.g., a rectangular prism, a pentagonal prism, hexagonal prism, heptagonal prism, or the like) in shape. In still other examples, the base 110 may be substantially cylindrical in shape or may have a substantially trapezoidal cross section. Various other shapes may be used without departing from the invention. [0034] The base 110 may include a base sidewall structure 112 having a first side 114, a second side 116 opposite the first side 114, a third side 118 extending between an edge of the first side 114 and an edge of the second side 116, and a fourth side 120 opposite the third side 118. The base sidewall structure 112 may also include a first end 122 and a second end 124 with a bottom portion 126 connected to the first end 122 of the base sidewall structure 112. The bottom portion 126 may be configured to support the container 100 on a surface such as a table, the ground, or the like. In some embodiments, the bottom portion 126 may also and/or include a support member 128 that may be attached to the bottom portion 126 to help provide a slip resistant surface for the container 100. The support member 128 may be a single member that may be integrally formed with the base 110 or may be attached after the base 110 has been formed. The support member 128 may have a size that encompasses at least 50 percent of the surface area of the bottom portion 126. While not shown, in some examples, the support member 128 may comprise a plurality of feet that are arranged on the bottom portion 126.

[0035] The base 110 may include a base opening 130 at the second end 124 of the base sidewall structure 112 (shown in FIGS. 3-5). The base opening 130 is configured to allow access to a base interior void 132 formed by the base sidewall structure 112 and the bottom portion 126.

[0036] The container 100 may include a lid 150. The lid 150 may be pivotally connected to the base 110 and be configured to rotate between an open configuration and a closed configuration, where the open configuration allows access to the base opening 130 and the base interior void 132 and the closed configuration prevents access to the base opening 130 and the base interior void 132. In some examples, rotating the lid 150 from the closed configuration to the open configuration includes rotating the lid about 90° from the closed configuration, or about 180° from the closed configuration, or about 270° from the closed configuration. As shown in FIG. 1, the base opening 130 may be covered by lid 150, when the container 100 is in a closed configuration. In some arrangements, the lid 150 may connect to the base 110 in a closed configuration using a press fit. Additionally, or alternatively, other securing systems or devices may be used to secure the lid 150 to the base 110, as will be discussed more fully herein. [0037] In some examples, the lid 150 may be hinged such that it is connected to (either removably or permanently) the base 110 at a hinge 142 and may be rotated about the hinge 142. The hinge 142 may be one of various types of hinges, including a continuous piano hinge, double hinge, ball joint hinge, living hinge, and the like. These and various other hinge arrangements may be discussed more fully herein. The hinge 142 may permit the lid 150 to be opened and rotated away from the base 110, to allow access to the base interior void 132 defined by the base 110 (e.g., via base opening 130). That is, the hinge 142 may facilitate rotation of the lid 150 from a closed configuration of the container 100 (e.g., when the lid 150 is in place covering the base interior void 132 formed by the base 110, as shown in FIG. 1) to an open configuration (e.g., when the lid 150 is not covering the base interior void 132 formed by the base 110, as shown in FIGS. 3-5), and vice versa.

[0038] The lid 150 may include an lid sidewall structure 152 having a first side 154, a second side 156 opposite the first side 154, a third side 158 extending between an edge of the first side 154 and an edge of the second side 156, and a fourth side 160 opposite the third side 158. The lid sidewall structure 152 may also include a first end 162 and a second end 164 with an upper portion 166 connected to the second end 164 of the lid sidewall structure 152. The upper portion 166 may be configured to act as a cover for the container 100 that could support items placed on top of the container 100. In some examples, the upper portion 166 may have a centrally located recess 168 along the upper portion to allow a second container to be placed on top of the upper portion 166. The lid 150 may further include a lid opening 170 at the first end 162 of the lid sidewall structure 152. The lid opening 170 is configured to allow access to a lid interior void 172 formed by the lid sidewall structure 152 and the upper portion 166 at the second end 164 of the lid sidewall structure 152. In most examples, a height of the lid sidewall structure 152 may be less than a height of the base sidewall structure 112. Thus, the volume of the base interior void 132 may be larger than the volume of the lid interior void 172.

[0039] In some arrangements, the container 100 may include a gasket 199 or other sealing device. The gasket 199 may be arranged in either the lid 150 or the base 110 and may aid in sealing the lid 150 and base 110 when the lid 150 is in a closed configuration. For example, in one example, the container 100 may be manufactured such that it is dust tight when tested for 8 hours and/or waterproof when tested for 30 minutes under 1 meter of water. In some embodiments, the container 100 may be capable of achieving an IP68 (as set forth by International Electrotechnical Commission) rating which specifies that there is no ingress of dust or complete protection from dust when tested for 8 hours and ingress of water in harmful quantities is not possible when the enclosure is immersed in water under defined conditions of pressure and time (at 1 meter of submersion). The IP68 dust test is 8 hours long and the enclosure is tested in a vacuum. The IP68 water test is 30 minutes long and the enclosure is tested with the lowest point of the enclosure 1 meter deep water.

[0040] In some examples, (and as best shown in FIGS. 12-14) the gasket 199 may be seated in a recess 174 formed in the lid 150 that extends around a perimeter of the lid 150. Additionally, in some examples, the container 100 may include a ridge 134 in the base 110 extending around a perimeter of the base 110. The gasket 199 may be placed between the recess 174 and the ridge 134. When the lid 150 is in a closed configuration, the ridge 134 having a shape corresponding to recess 174 may contact the gasket 199 and compress the gasket 199 and aid in sealing the lid 150 and the base 110 in the closed configuration as shown in FIGS. 12-14. In some examples, the gasket 199 may be a traditional gasket having a substantially circular cross section. In other arrangements, the gasket 199 may include strategically placed cut-outs that may reduce or eliminate a need for a vent (e.g., a vent to prevent lid lock). The gasket 199 may aid in maintaining a seal between the interior of the container 100 and the outside environment, and in some examples, the gasket 199 may aid in maintaining the temperature of the articles contained within the container 100. Alternatively, the gasket 199 may be arranged in a recess or channel formed in the base 110.

[0041] The container 100 may include additional features, such as a lanyard 198, shown in FIG. 2, to allow a user to carry the container 100 or attach the container 100 to other objects. The lanyard 198 may connect to the base on the third side 118 to the fourth side 120 and extends along the bottom portion 126. As shown in the illustrated example, the support member 128 may have a groove 136 (or pair of grooves) that receives and guide the lanyard 198 along the bottom portion 126. In addition, the third side 118 and fourth side 120 of the base sidewall structure 112 may include guide rails 138 to engage and guide the lanyard 198 along the third and fourth sides 118, 120. The base sidewall structure 112 may also include connecting members 140 adjacent the guide rails 138 to secure the lanyard 198 to the base 110 of container 100. The guide rails 138 and connecting members may be integrally formed with the base 110.

[0042] As shown in FIGS. 3, 4, 5, and 12-15, the lid 150 may include a divider 178 that is pivotally connected to an interior portion of the lid 150 to separate any items that may be stored in a lid interior void 172from the base interior void 132. The divider 178 may extend across the lid opening 170 separating the base interior void 132 from the lid interior void 172. The divider 178 may have a front side 179 and a rear side 180 and an integrated hinge 181 formed along a first side 182 that is pivotally connected to the lid 150 at a hinge receiver 175 of the lid 150. The integrated hinge 181 may include a plurality of apertures spaced from the edge of the first side 182. In addition, the integrated hinge 181 may be located on an angle to the front side 179 and may be snap-fit into a hinge receiver 175 of the lid 150 to secure the divider 178 to the lid 150. As such, the divider 178 is releasably secured to the lid 150. The divider 178 may include a plurality of elongated openings 184. The elongated openings 184 may extend across a portion of the divider 178 in a direction generally oriented from the first side 182 to a second side 183 opposite the first side 182. Each elongated opening 184 may have a length, L, extends at least 50 percent of the width, W, of the divider 178, or between a range of 55 percent and 80 percent of the width, where the width, W, is the distance from the first side 182 to the second side 183. Alternatively, the divider 178 may be a continuous surface without openings.

[0043] When the divider 178 is installed, the second side 183 of the divider 178 may be selectively secured to the lid 150 to prevent rotational movement of the divider 178 as best illustrated in FIG. 15. The divider 178 may include a central recess 185 along the second side 183 forming a pair of tabs 186. Each tab 186 may have an engagement receiver 187 that forms a friction or snap fit with a lid engaging member 177 that extends from an interior surface of the lid 150. The lid engaging member 177 may fit into a groove formed by the engagement receiver 187 of the divider 178.

[0044] The container 100 may also include a removable tray 188. The tray 188 may allow another level for a user to store items in the container 100. The tray 188 rests along a shelf 148 that extends along an inner perimeter of the base interior void 132. The tray 188 may include an upper ledge 190 with a perimeter wall 192 that extends from an inner edge 194 of the upper ledge 190 to a bottom wall 196 forming the bottom portion of the tray 188. The volume formed by the perimeter wall 192 and the bottom wall 196 of the tray may form an upper storage region of the base interior void 132. The tray 188 may have a tray depth that is less than a depth of the base sidewall structure 112 of the base 110 such that the bottom wall 196 of the tray 188 is spaced from the bottom portion 126 of the base 110, which allows for a secondary storage region within the base interior void 132 underneath the bottom wall 196 of the tray 188. As noted, since the tray 188 is removable, with the tray 188 removed, the base interior void 132 may form a single storage region within the base 110.

[0045] The upper ledge 190 may be continuous along the perimeter wall 192 to form a solid upper ledge 190. Similarly, the perimeter wall 192 and the bottom wall 196 may be continuous such that no holes or apertures are present in the tray 188. Alternatively, the perimeter wall 192 and/or the bottom wall 196 may include apertures. In some examples, the shelf 148 may be continuous along the inner perimeter of the base interior void 132, while in other examples, the shelf 148 may be interrupted or a plurality of mounts (not shown) may be positioned along an interior surface of the base sidewall structure 112 such that the mounts form a planar surface to support the tray 188.

[0046] The divider 178 and the tray 188 may have an elastomeric material coating to provide a soft touch and feel and for storing delicate objects. This divider 178 and/or the tray 188 may be overmolded onto a more rigid base, or in some cases, the divider 178 and/or the tray 188 may be formed from an elastomeric material. The elastomeric materials used to form, or partially form, an exemplary divider 178 and/or tray 188 may materials such as or including natural and synthetic rubbers, thermoplastic urethanes (TPU), thermoplastic elastomers (TPE), or other similar materials.

[0047] In some arrangements, the container 100 may also include a latch assembly 200. As best illustrated in FIGS. 16A-20, the latch assembly 200 may have a locked position and an unlocked position, where the latch assembly 200 is configured to lock the lid 150 when the lid 150 is in a closed configuration. The latch assembly 200 may include a latch body 210 that is pivotally connected to the lid 150, a latch button 230 that is slidably connected to the latch body 210, and a latch-locking arm 250 pivotally connected to the latch body 210 around a latch pin 270 that is connected to the latch body 210. The latch assembly 200 may also include a latch button biasing member 280 that exerts a vertically oriented force onto the latch button 230, and a locking arm biasing member 282 that exerts a rotational force on the latch-locking arm 250. The latch button 230 may have a latch button-locking member 232, and the latch-locking arm 250 may have an arm-locking member 252. In some examples, the latch assembly 200 may further comprise an interlocking pawl 288 that is rotatably attached to the latch body 210 via a pin connection where the interlocking pawl 288 is located closer to an upper edge 212 of the latch body 210 than a lower edge 214 of the latch body 210. As will be described in more detail below, when the latch assembly 200 is moved to the locked position, the latch-locking arm 250 engages the base 110 and rotates against the rotational force of the locking arm biasing member 282 and the latch button 230 moves against the vertically oriented force of the latch button biasing member 280 until the latch button-locking member 232 engages the arm-locking member 252 as shown in FIGS. 16A-16D.

[0048] FIGS. 16A-16D illustrates the movement of the latch assembly 200 from an unlocked position to a locked position. As shown in FIG. 16A, the latch assembly 200 is in an unlocked position with the latch-locking arm 250 extending away from the latch body 210 toward the base 110. The interlocking pawl 288 may prevent the latch-locking arm 250 from inadvertently engaging the latch button 230 into its locked position when the container 100 is in an open configuration (e.g., the base 110 and the lid 150 are separated from each other on at least one side). The interlocking pawl 288 may include a central member 290 with an aperture 292 extending through the central member 290, a first protrusion 294 extending outward from the central member 290, and a second protrusion 296 extending outward from the central member 290 opposite the first protrusion 294. The first protrusion 294 may contact the latch button 230 when the latch assembly 200 is in an unlocked position to prevent the latch button 230 from moving upward toward an upper edge 212 of the latch body 210. The second protrusion 296 of the interlocking pawl 288 may have a curved outer surface that may contact the lid 150 when the latch assembly 200 is in an unlocked position to prevent the latch-locking arm 250 from locking before the lid 150 is in the closed configuration. In addition, a pawl biasing member 298 may exert a rotational force on the interlocking pawl 288 to keep the interlocking pawl 288 in contact with the latch button 230 when the container 100 is in an open configuration. Since the latch button 230 cannot slide, the latch-locking arm 250 cannot rotate to inadvertently engage the latch button 230 prior to the lid 150 being closed onto the base 110. For example, the pawl biasing member 298 may be a torsion spring that exerts a rotational force to bias the first protrusion 294 toward the latch body 210 (i.e., a clockwise direction as shown in FIG. 16A). The rotary motion of the interlocking pawl 288 may be controlled by a cam-like interaction between the outer surface of the second protrusion 296 of the pawl 288 and the lid 150. In some examples, the corresponding engagement region 176 with a corresponding curved surface to engage the curved outer surface of the second protrusion 296.

[0049] FIGS. 16B and 16C illustrate the latch assembly 200 engaging the base 110 causing the latch assembly 200 to begin to move from an unlocked position to a locked position. As a locking arm engaging member 254 of the latch-locking arm 250 engages a receiver 144 positioned under a lip 146 that extends outward along a first side 114 of the sidewall structure (as best shown in FIG. 13), the latch-locking arm 250 begins to rotate towards the latch body 210 (i.e., the latch-locking arm 250 rotates in a counterclockwise direction as shown in FIG. 16B). In some examples, the lip 146 may extend outward along an entire perimeter of the base 110. The receiver 144 may have a concave cross-sectional shape, and the locking arm engaging member 254 may have a convex shape cross-sectional shape. As the latch-locking arm 250 contacts the base 110, the latch-locking arm 250 begins to move underneath the base 110. The rotational movement of the latch-locking arm 250 may cause the latch button-locking member 232 to contact and ride up along an outer surface 258 of the arm- locking member 252. As the latch button-locking member 232 moves along the outer surface 258, the latch button 230 may translate upward in a sliding motion toward an upper edge 212 of the latch body 210. As the latch-locking arm 250 rotates, the entire latch assembly 200 rotates towards a vertical orientation.

[0050] FIG. 16D illustrates the latch assembly 200 in a locked position. In the locked position, the latch button-locking member 232 engages the arm-locking member 252, where the latch-locking arm 250 is in a substantially vertical orientation. Each locking member 232, 252 may include a locking surface 234, 256 respectively that confront each other when the latch assembly 200 is in a locked position. Further, when in a locked position each locking surface 234, 256 may be substantially vertically oriented. As the latch button-locking member 232 moves the curved outer surface 258 of the arm-locking member 252, the latch button-locking member 232 eventually reaches an upper edge 260 of the curved outer surface 258. The upper edge 260 may also be the upper edge of the locking surface 256 such that once the latch button-locking member 232 passes the upper edge 260 of outer surface 258, the latch button-locking member 232 drops such that the locking surface 234 moves downward to confront the locking surface 256 of the arm-locking member 252.

[0051] To move the latch assembly 200 from a locked position to an unlocked position, the above described process is reversed as shown in FIGS. 17A-17C. A user may push the latch button 230 upward where locking surface 234 disengages from locking surface 256. The locking arm biasing member 282 may then cause the latch-locking arm 250 to rotate towards the base 110 causing the latch button-locking member 232 to slide down the outer surface 258 of the arm-locking member 252. In addition, the latch button biasing member 280 exerts a downward force on the latch button 230 to help pull the latch button 230 and assist the latch button-locking member 232 to slide down the outer surface 258 of the arm-locking member 252. In some examples, the latch assembly 200 may operate without the interlocking pawl 288.

[0052] FIGS. 18-20 illustrate the latch assembly 200 disconnected from the lid 150. As discussed above, the latch assembly 200 may include a latch body 210, a latch button 230 that is slidably connected to the latch body 210, and a latch-locking arm 250 pivotally connected to the latch body 210 around a latch pin 270 that is connected to the latch body 210.

[0053] The latch body 210 may include an upper edge 212, a lower edge 214, and an outward facing surface 216 extending between the upper and lower edges 212, 214. On the inward side 217 opposite the outward facing surface 216, the latch body 210 may further comprise a pair of hinge members 223, a latch pin receiver 218, a pair of latch button guides 220, and a button biasing member receiver 222. The hinge members 223 may be configured to receive a lid latch pin 272 to connect the latch assembly 200 to the lid 150. A latch pin receiver 218 may include an aperture 228 arranged on a side surface 226 of the latch body 210 and also include a pin support 221 that receives the latch pin 270 on at least two sides. In addition, each latch button guide 220 may be a protrusion arranged on either side of the latch button 230 to keep the latch button 230 moving in a linear orientation. The button biasing member receiver 222 may comprise a recess or pair of recesses in the latch body 210 that are configured to hold a portion of the latch button biasing member 280. The latch button biasing member 280 may be a compression spring or pair of compression springs to exert a linear force toward the lower edge 214 onto the latch button 230. This linear force helps to keep the latch button-locking member 232 engaged with the armlocking member 252. In an exemplary latch assembly 200 that includes an interlocking pawl 288, the latch body 210 may further include a pawl receiver 224 that receives a pin and a pawl biasing member 298.

[0054] The latch button 230 may include a latch button-locking member 232 that extends outward from a rear surface 236, while the front surface 238 may be configured to confront and slidably move along an interior surface of the inward side 217 of the latch body 210. The latch button 230 may further include a bottom surface 240 to provide an interface for a user to exert an upward force to disengage and/or engage the latch assembly 200. A latch button pin receiver 242 may be positioned above the bottom surface 240. The latch button pin receiver 242 may comprise an aperture that receives the latch pin 270. The latch button pin receiver 242 may have a height that is larger than a diameter of the latch pin 270 to enable the latch button 230 to slide along the latch body 210, while the latch pin 270 remains fixed to the latch body 210. For example, a height of the latch button pin receiver 242 may be two times greater than a diameter of the latch pin 270. In some examples, the height of the latch button pin receiver 242 may be within a range of 1.5 to 3 times greater than a diameter of the latch pin 270. As another feature, the front surface 238 may include a recess substantially aligns with the button biasing member receiver 222 in the latch body 210 that are configured to hold a portion of the latch button biasing member 280.

[0055] The latch button-locking member 232 may be centrally located on the latch button 230 and may include a locking surface 234 that extends substantially perpendicular to the bottom surface 240. The latch button-locking member 232 may include a slide surface 244 adjacent to a lower edge of the locking surface 234, where the slide surface 244 may be configured to slide along the outer surface 258 of the arm- locking member 252. The slide surface 244 may be arranged at an acute angle (i.e., within a range of 1 degree and 89 degrees) to the locking surface 234. In some examples, a stop 245 may extend from an upper surface 246 of the latch button 230, where the stop is configured to contact the interlocking pawl 288 to prevent the latch button 230 from inadvertently moving when the latch assembly 200 is in an unlocked position.

[0056] The latch-locking arm 250 may have a front side 268 that faces the latch body 210 and a rear side 269 that faces the base 110. The latch-locking arm 250 may include an arm-locking member 252 that is substantially centered along the latch-locking arm 250, a pair of locking arm engaging members 254 arranged on each side of the armlocking member 252, and where each engaging member 254 may be spaced from the arm-locking member 252. Further, each engaging member 254 may have a free end 262 with a curved or convex cross-sectional shape that engages the receiver 144 on the base 110 and a fixed end 264 that receives the latch pin 270. As The locking arm biasing member 282 may be a torsional spring or a pair of torsional springs that is (are) connected to the latch pin 270 and exert a rotational force(s) on the engaging members 254. In addition, as shown in FIG. 14, the free end 262 of each engaging member 254 may include a locking surface 266 that may confront and contact a locking member 149 positioned in the receiver 144 of the base 110. The locking surface 266 may be substantially parallel to the locking surface 256 of the armlocking member 252 and may be spaced forward (toward the latch body 210) from the locking surface 256.
