DETAILED DESCRIPTION

[0035] Embodiments of the present disclosure are described herein. It is to be understood, however, that the disclosed embodiments are merely examples and other embodiments can take various and alternative forms. The figures are not necessarily to scale; some features could be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ embodiments of the present disclosure. As those of ordinary skill in the art will understand, various features illustrated and described with reference to any one of the figures can be combined with features illustrated in one or more other figures to produce embodiments that are not explicitly illustrated or described. The combinations of features illustrated provide representative embodiments for typical applications. Various combinations and modifications of the features consistent with the teachings of this disclosure, however, could be desired for particular applications or implementations.

[0036] Reference is first made to Figs. 1 and 2 of the drawings which illustrate perspective views of the front and back of an example of a desk system, referred to generally as a desk system

10 herein. Components of the desk system 10 are arranged with one another such that the desk system 10 may transition between multiple configurations and positions. For example, the desk system 10 may transition between at least a collapsed or folded position and an expanded or open position. The desk system 10 may include an integrated seating and work surface that can easily fold for simple and convenient storage and easy transport. When assembled the system includes an adjustable work desk with an integrated clip system that allows for a variety of desk and work accessories to be attached to the edge of the work surface leaving the entire work surface clear. These accessories may provide, for example, storage, lighting, entertainment, and other useful devices.

[0037] In one example of the desk system 10, there is no tool assembly required and as previously indicated it can readily be folded flat for easy storage and portability and quickly opened and adjusted to a desired position or configuration. The desk system may include a top with a channel cut and a plastic trap which permits insertion and attachment of the various accessories. The desk system 10 may provide a custom workplace without sacrificing desk space. Adjustability of the desk system 10 may accommodate a variety of different sized users and may positively influence a user's posture while seated.

[0038] While several modifications will be illustrated and described the common elements will be given the same numerals. It is noted that various elements will change in detail but their functions will not.

[0039] Continuing to refer to Figs. 1 and 2, the desk system 10 includes a desk top 12 supported by columns consisting of inner and outer columns 14, 16. The inner column 14 is connected to a desk top 12 by a pivot assembly 18 so the desk top 12 can be pivoted relative to the inner column 14. The inner column 14 may have an upper end and the outer column 16 may have a lower end. The inner column 14 and the outer column 16 may have a telescoping relationship. Various shapes may be suitable for the desk top 12. For example, the desk top 12 may define a rectangular or square shape. A configuration of the desk top in Fig. 1 may be referred to as a landscape configuration herein. A work surface lock out mechanism 62 (see Fig. 9b) may be provided to lock the desk top 12 in position when the assembly is moved to one or more positions including an open position. For example, the lock out mechanism 62 may be selectively engaged to orient the desk top 12 in the one or more positions. It is contemplated that other suitable lock mechanisms may be available to secure the desk top 12 and inner column 14 in a position. [0040] The inner and outer columns 14, 16 may define openings (not shown) for a pin 20 to extend therethrough and retain the columns 14, 16 in the desired position. For example, the desk top 12 may translate to adjust a distance between an underlying surface and the desk top 12 and/or to adjust a distance between the underlying surface and a seat assembly 26.

[0041] A pivot assembly 24 assists in enabling pivotal movement of the outer column 16 and a knee support assembly 22. The knee support assembly 22 may include one or more knee pads to assist in supporting a user positioned adjacent the desk top 12. It is contemplated that the knee support assembly 22 may be a single component or may include more than one component, such as multiple knee pads.

[0042] We turn now to the seat assembly 26 which is connected to a seat 28. The seat 28 is connected to a front support base 30 through a dual column assembly 32. The dual column assembly 32 may include a first elongate member 33. The first elongate member 33 may have a first end for resting on the underlying surface and a second end. The dual column assembly 32 may include two first elongate members 33 spaced apart from one another. The seat 28 may be mounted to the dual column assembly 32 for pivotal movement. For example, the seat 28 may be mounted to the second end of the first elongate member such that when the desk system 10 is oriented in a collapsed position (further described below) the seat 28 may pivot to assist in providing a more compact configuration of the desk system.

[0043] The knee support assembly 22 may be connected to a rear support base 34 through a column assembly 36. The seat assembly 26 may include a second elongate member 37. The second elongate member 37 may include a first end for resting on the underlying surface and a second end. The seat assembly 26 may include two second elongate members 37. The first elongate member 33 and the second elongate member 37 may share a common pivot and be pivotable relative to one another in a scissor-like manner. For example, the first elongate member 33 and the second elongate member 37 may share a pivot 39.

[0044] To permit pivotal movement of the seat assembly 26 and the knee support assembly

22 there is provided a pivot assembly 38. For example, the pivot assembly 38 may include a link 42. To facilitate positioning of the seat assembly 26 relative to the knee support assembly 22 a support plate 40 may be secured between braces 36a and 36b of the column assembly 36. The link 42 may be provided between a plate 40 and the seat assembly 26. One end of the link 42 may be pivotally connected to the seat assembly 26 at a pivot 44. The link 42 may operate as a support member and be cooperable with the first elongate member 33 and the second elongate member 37 to selectively retain the elongate members in one or more crossed orientations. The other end of link 42 may have a transversely extended rod 46 connected thereto which may be adjustably positioned between slots in plate 40 to receive rod 46 in various positions. For example, the link 42 may be a strut pivotally connected to one of the elongate members and engageable with the other of the elongate members at one or more spaced apart locations in order to vary a height of components of the desk system 10. The link 42 may also be pivotally attached to one of the elongate members.

[0045] Figs. 3 and 4 provide front view 50 and back view 52 of the desk system 10. The components thereof are appropriately numbered.

[0046] The first and second elongate members 33, 37, the seat 28, the inner and outer columns 14, 16, and the desk top 12 may be arranged with one another to transition between at least a collapsed position and an expanded position. For example, Fig. 5 a is a schematic view of the desk system 10 in the expanded position and Fig. 5b is a schematic view of the desk system 10 in the collapsed position. The desk system may define a height of less than one foot relative to the underlying surface when in the collapsed position.

[0047] Fig. 6 shows the desk system 10 in the collapsed position for storage or transport. For example, the desk system 10 may fit under a user's bed or within a user's closet when in the collapsed position. As another example, the desk system 10 may be more conveniently transportable when in the collapsed position in comparison with the expanded position.

[0048] Fig. 7 shows another example of an embodiment of the desk system 10 oriented in the expanded position. In this example, the knee support assembly 22 is shown as a single component mounted to the second elongate member 37.

[0049] Shown attached to the desk top 12 are various accessories including a fan 54, speakers 56, and a lighting system 58. Examples of other accessories which may be removably attached to the desk top 12 include, but are not limited to, a mobile phone dock, a tablet dock, a cup holder, a utensil receptacle, a speaker, a snack tray, a makeup mirror, a cord organizer, a book holder, a file receptacle, one or more clips, or an art supply holder. The seat 28 and the knee pads of the knee support assembly 22 are of a different design than Figs. 1 through 4 but the components thereof are otherwise similar.

[0050] Fig.8 illustrates another embodiment showing slightly different designs of various accessories.

[0051] Fig. 9a illustrates another embodiment that includes similar components as the other embodiments but takes slightly different shapes and sizes that indicate the wide variations that are possible involving applicant's novel concepts.

[0052] Fig. 9b is a detailed view of the open work surface lock-out mechanism 62 for locking the work surface in a position during use.

[0053] Fig. 9c shows the main arm dual lock-out system 60 for locking the main column in position during use.

[0054] Figs. 9d and 9h illustrate the novel slot system for attaching various accessories. For example, the desk top 12 may define a side face 67 extending about a perimeter thereof. The side face 67 may have a groove 69 extending about at least a portion of the perimeter of the desk top 12. In another example, the groove 69 may extend around substantially all of the perimeter of the desk top 12. The groove 69 may be sized to receive a fastener tab of one of the accessories. The fastener tab may be mounted to the respective accessory for pivotal movement. For example, the pivotal relationship between the fastener tab and respective accessory may be such that the accessory may pivot between at least a first position in which the accessory does not extend over a portion of the desk top 12 and a second position in which the accessory extends over a portion or contacts the desk top 12. For example, in the collapsed position the accessory may extend over and contact the desk top 12 for storage or transport purposes.

[0055] Fig. 9e shows an exploded view of various examples of components of the desk system 10.

[0056] Fig. 9f is a side perspective view of the embodiment shown in Fig. 9a. [0057] Fig. 9g is a partial perspective view of the embodiment shown in Fig. 9a.

[0058] Fig. 9i illustrates the embodiment of Fig. 9a in the collapsed position for storage or transport.

[0059] Fig. 9j includes partial perspective views of the desk system 10 including a view having a user positioned thereon. In this example, a posture of the user positioned on the desk system may be defined by a substantially upright seated position optimal for spinal health of the user.

[0060] Figs. 10 and 11 show an example of a swivel mechanism which may assist in rotating the desk top 12 relative to the supporting structure and about an axis normal to the desk top 12. Turning now to Fig. 10 there is illustrated an enlarged perspective view of the pivot assembly 18. It is to be noted that the pivot assembly 24 is similar to the pivot assembly 18.

[0061] In Fig. 10 there is shown the inner column 14 connected to a shaft 70 which is rotatably mounted. Connected to one end of the shaft 70 is a toothed wheel 72 which engages a mating toothed member 74. A handle 76 is connected to a shaft 78 that is threaded into a knob 80 in a fixed position. The handle 76 may be turned counter clockwise and the toothed wheel 72 may be loosened and disengaged from the toothed member 74 such that the column 14 is free to rotate and move the desk top 12 to a desired angled position. The handle 76 may be turned clockwise to lock the toothed wheel 72 and the toothed member 74 together and lock the desk top 12 in a fixed position.

[0062] The pivot assembly 24 for permitting movement of the column 16 is similarly designed to adjust or retain the column assembly in a fixed position.

[0063] The desk top 12 may be rotated relative to an axis normal to the desk top 12. For example, the desk top 12 may rotate between 90 and 180 degrees. Bottom surface projections 82 of the desk top 12 may fit into corresponding openings 84 that are formed in a plate 86 to which is secured toothed member 74. In a normal fixed position a first plate 86 and a second plate 81 may be retained in their relationship by the knob 90 to which is connected a shaft (not shown) which when loosened permits disengagement of the projections 82 from the openings 84 which permits rotation of the desk top 12. When the plates 81, 86 are in their relocated position the knob 80 may be tightened to retain the plates in the new position.

[0064] Figs. 13 through 15 show another example of the desk system 10. Figure 13 shows the desk system 10 in the expanded position with the desk top in the landscape configuration and various accessories mounted thereto. Figure 14 shows the desk system 10 in an easel configuration in which the desk top 12 is oriented in a substantially upright position relative to the underlying surface. Artists are one example of a type of user which may utilize the easel configuration. In this configuration, accessories, such as a light, speakers, and a utensil receptacle may be mounted to the desk top 12 via the groove 69 and respective fastener. Figure 15 shows the desk system 10 in the collapsed position for transport or storage.

[0065] Figs. 16 and 17 show an example of an accessory fastener, referred to generally as an accessory fastener 100 herein. The accessory fastener 100 may include a mount 104, a first fastener tab 108, and a second fastener tab 110. The accessory fastener 100 may be mounted to a desk top, such as the desk top 12. For example, the first fastener tab 108 may be sized for disposal within a groove, such as the groove 68 of the desk top 12. The second fastener tab 110 may be arranged with the first fastener tab 108 to assist in orienting the accessory fastener 100 relative to the desk top 12. An accessory, such as an accessory 112 may be mounted to the accessory fastener 100 at, for example, the mount 104. The mount 104 may be, for example, a nub or pin sized for reception within the accessory 112 such that the accessory 112 may rotate about an axis in line with the mount 104. For example, Fig. 17 shows an example in which the accessory 1 12 may rotate between a position in which the accessory 112 does not extend over a portion of the desk top 12 to a position in which the accessory 112 extends over the desk top 12. Fig. 18 shows an example in which multiple accessories are folded onto the desk top 12 where the desk system 10 is in the collapsed position.

[0066] The desk systems described above provide users with a workspace option in which a stored desk system may be easily opened as a fully assembled product and adjust to fit their body. Transition between the various positions and configurations does not require additional parts or tools. Accessories may attach to the desk simply and allow the user to customize their workspace according to work needs and style and without obstructing work space of the desk top. The accessories may also fold against the desk top storage. Additionally, the seat and knee supports may positively influence the user's posture while working at the desk and may be adjusted to accommodate various user body types and sizes.
