FIELD OF THE INVENTION

[0001] The present invention generally relates to accessories for pushable devices. In particular, the present invention is directed to an Attachment for a Pushable Device.

BACKGROUND

[0002] Presently available jogging strollers generally cause the user— the jogger pushing the stroller— to break their natural running or walking rhythm as the user must (at least semi-frequently if not continuously) push the jogging stroller in a desired direction and at a desired rate directly with one or both hands, forearms, or other body part. Some strollers attempt to overcome this issue by extending the geometry' of the stroller to allow for fuller leg strides, but natural arm swing is still not possible when maintaining contact with the stroller. Thus, by maintaining direct contact with the stroller with a body part, a jogger is unable to freely swing their arms in movement with their legs during their running or walking routine. Running, jogging, and walking, therefore, becomes difficult, tedious, and potentially injurious when the natural movement of the user’s arms and legs is interrupted.

[0003] Some users attempt to overcome the lack of natural motion by“letting-go” of the stroller for periods of time, e.g., pushing the stroller ahead and catching up to it as it slows down. However, this can result in the stroller accelerating faster than the user (e.g., rolling uncontrollably down a hill), the stroller tipping over, the stroller becoming unstable on certain surfaces (e.g., loose gravel or dirt), or the stroller tripping the user when contact resumes. With the safety of a child in the stroller being paramount, the disadvantages an discomfort caused by the interruption of a user’s stride has driven many users away from jogging while pushing a stroller altogether.

[0004] Attachments for jogging strollers have been developed, which allow users to remove their hands or forearms from a handle or grip of the stroller. These attachments can allow for a more natural walking or running motion and stride. However, the continuous rolling motion of the stroller can be out of step with the walking/running motion of the pusher, resulting in jarring effects for both the pusher and the stroller occupant. Moreover, such attachments do not allow for natural steering of the stroller while the user removes their hands from the stroller, hindering the frill running experience. Therefore, there is a need for an improved hands-free attachment for a stroller. SUMMARY OF THE DISCLOSURE

DESCR IPTION OF THE DISCLOSURE

[0014] An attachment for a pushable device of the present invention connects a jogger or walker (referred to herein as a“pusher” or“user”) to a pushable device, which may include, as used herein, any similar rolling device to be pushed by a user, such as a stroller, and allows for a natural running or walking motion while pushing the device in front of the user. In some embodiments disclosed herein, the attachment includes dampening functions to react to the independent movements of the pusher and device, which, in conjunction with an overall geometry that limits interference with the natural gait of a pusher’s arms and stride, results in more natural motion for the pusher and a smoother ride for an occupant and/or contents of the device. In another embodiment, the attachment provides a pivotable substantially rigid connection between the pushable device and the user. (As used herein, rigid means that a component or connected components do not significantly distort under forces typically involved by a user pushing a stroller at a walking or running pace on typical surfaces such as asphalt, concrete, gravel, dirt roads, etc.) Embodiments of an attachment disclosed herein allow the pusher’s body movements to steer the device, and, while allowing for substantially hands-free control of the device, also reduce unwanted movements, such as body movements that could result in the front of the device bouncing, being translated into the device from the pusher’s motions. Embodiments of the attachments disclosed herein allow pushers to comfortably

nm/jog/walk hands-free while keeping control of a pushable device in front of them.

[0015] Turning now to the figures, and in particular, FIGS. 1 to 4, an embodiment of an attachment, attachment 100, is shown. In this embodiment, attachment 100 securely mounts to a pushable device, such as stroller 101, and couples to a pusher 103 proximate the hips of the pusher. At a high level, attachment 100 includes a user assembly 104, an arm assembly 108, and a stroller mount 112. The combination of user assembly 104, arm assembly 108, and stroller mount 112 allow for natural movement of pusher 103 while walking or jogging and for constant control over stroller 101, thereby ensuring the safety of the occupant of the stroller.

[0016] An embodiment of a user assembly 104 is shown in FIG. 2. In general, user

assembly 104 is configured to sit high on the waist of pusher 103, typically above the belt-line. User assembly 104 allows for a flexible, yet firm connection to arm assembly 108; is readily removable from pusher 103 when desired; and provides a stable pivot point for arm assembly 108. User assembly 104 is preferably designed and configured to fit a wide variety of users via the inclusion of an adjustable connection system 202, e.g., a squeeze buckle and adjustable straps as shown in the embodiment of user assembly 204 shown in FIG. 6. Adjustable connection system 202 can take on other configurations and connection mechanisms, such as, but not limited to, hook and loop fastening systems, snaps, belts, and the like. In an embodiment, user assembly 104 includes apertures 114 (e.g., 114A, 114B) for connection to a portion of arm assembly 108. In addition, user assembly 104 may include other components, such as a rear pouch 107 and/or a holster for a water bottle 109.

[0017] With reference now to FIG. 3, ami assembly 108 is disposed between pusher 103 and stroller 101. Although arm assembly 108 is typically rigid in construction so as to facilitate hands- free steering of stroller 101, the arm assembly is configured to allow for some longitudinal movement so as to accommodate the natural hip movements of the pusher. In an embodiment, and at a high level, ami assembly 108 includes a push arm assembly 116, stroller connector 120, and a user assembly connector 124. In an embodiment, push arm assembly 1 16 is a telescopic, partially nesting, two-part assembly (including a forward ami 128 and a rear ami 132) that allows for pusher 103 to adjust the distance from stroller 101.

[0018] Push ami assembly 116 can be designed and configured to slightly“shimmy” fonvard and back to reduce steering sensitivity and hip motion from the pusher 103 via the use of a dampener 136. In an embodiment, dampener 136 is also used to couple forward arm 128 wdth rear arm 132. Front ami 128 includes a first portion 144A and second portion 144B that couple to the handlebar of stroller 101 at their respective distal ends, 148A and 148B. So as to allow push ami assembly 116 to have positive connections with stroller 101 while still allowing for some motion, e.g., pivoting, first portion 144A and 144B may be attached to the handle of stroller 101 via clamp mechanisms 140 that allow push arm assembly 116 to rigidly interface with the stroller, while pivoting with respect to the handlebar. Pivoting push arm assembly 116 during use helps prevent the front wheel(s) of stroller 101 from bobbing up and down off the ground and thus provides a more comfortable experience for pusher 103 and the occupant of stroller 101.

[0019] Rear ami 132 is coupled to front arm 128 and includes left and right hip-wraps 146 and a central telescopic tube 150. Central telescopic tube 150 allows for additional adjustment of arm assembly 108 to conform to the stride and body geometry of the user as well as the geometry of the stroller 101. In an embodiment, central telescopic tube 150 is formed by two‘half-tubes’ made up from two identical arms (e.g., 154A, 154B). Central telescopic tube 150 is fastened independently on each of the left and the right sides. These amis 154A and 154B nest together are designed to “shimmy” forward and back more than the front arm 128 to absorb unwanted hip motion from pusher 103. Each of arms 154A and 154B terminates in a respective hip-wrap 146, for example hip- wrap 146 A and hip-wrap 146B.

[0020] In operation, the user attaches the handle bar attachment mechanisms 140 to the handlebars of stroller 101 at the desired spacing. In an embodiment, four of these attachment mechanisms may nest into position to make a more rigid connection onto, typically, foam clad bent metal bars of the handle of stroller 101. In an embodiment, internal ribbed features of attachment mechanism 140 cut into the foam so that they are rigidly set into place to provide a crisp interface without the softness typically associated with the foam handlebars. Additionally, the attachment mechanism 140 may include two clasps (not shown) that are counter sprung with torsion springs (not shown) such that the clasps tend to always rvant to close around the handlebar, to aid in ease of use. These clasps are integral with attachment mechanisms 140 (typically residing on the periphery of the attachment mechanism) and using the single clasp that may employ an over-center linkage to snap into place so that running attachment 100 is attached to the stroller. The release of the single clasp can quickly remove the running attachment 100 from stroller 101. Optionally, a safety tether (not shown) is attached to stroller 101 and to running attachment 100. [0021] User 103 then fastens the user assembly 104 to their torso, preferably just above the waist line. The slightly cantilevered positioning between this pivot point and ami assembly 108 creates a slightly flexible connection that assists with dampening.

[0022] FIGS. 5 to 10 show another embodiment of an attachment, attachment 200, for hands free pushing of a pushable device by a user. As with attachment 100, attachment 200 allows a user 103 to push the pushable device, such as stroller 101, without using hands or forearms on a handlebar or similar connection point of the device. Attachment 200 includes a user assembly 204 that removably attaches around the waist of pusher 103, an arm assembly 208 that connects user assembly 204 to stroller 101, and includes a push arm assembly 216 and a user assembly connector 224.

[0023] User assembly 204, shown apart from running attachment 200 in FIG. 6, connects arm assembly 208 to user 103. User assembly 204 may be made of any suitable material, such as, but not limited to, nylon or PVC fabric, and may be secured around the pusher’s 'aist by any suitable mechanism, including ties, hook-and-loop straps, and side release buckles 202. User assembly 204 may also include attachment portions 218 (e.g., 218A, 218B) for receiving and securing portions of push arm assembly 216. User assembly connector receptors 218 may be pockets or pouches, and may be tightened or secured by any suitable mechanism or combination, such as zippers, friction, buckles, and hook-and-loop straps. Safety straps 220 (e.g., 220A, 220B) are preferably included so that push arm assembly 216 remains secured to user assembly 204 even if push arm assembly 216 accidentally detaches from user assembly connector receptors 218.

[0024] User assembly connector 224 and push arm assembly 216 are designed to be detachably connected to each other to form ami assembly 208, which is preferably a substantially rigid attachment segment and is shown unattached to a stroller or user assembly 204 in FIGS. 7-10. User assembly connector 224 is designed to be attached to user assembly 204 and engage with a user’s waist/torso so that the user can push an attached stroller. User assembly connector 224 includes a rod or tube 228 that is connected to a push ami assembly 216. Tube 228 projects away from user assembly connector 224 and is configured to connect to a counterpart member of push arm assembly 216 (discussed below). User assembly connector 224 is preferably rigid. (As used herein, rigid means that a component or connected components do not significantly distort under forces typically involved by a user pushing a stroller at a walking or running pace on typical surfaces such as asphalt, concrete, gravel, dirt roads, etc.) User assembly connector 224 includes a first portion 232 designed to engage with the front of a user’s waist, preferably at about the belt level. On opposite ends of first portion 232 are a right curved portion 236 and a left curved portion 240, which are designed to engage with the user’s right side and left side, respectively, preferably at about the same level (height) as first portion 232. In this way. the overall forward motion of the user/pusher is smoothly transferred through stroller attachment system to an attached stroller.

[0025] Push arm assembly 216 includes a rod or tube 244 and a stroller handle engagement member, stroller handle connector 248. Tube 244 is designed and configured to connect to tube 228 to form a substantially rigid connection between push arm assembly 216 and user assembly comiector 224. For example, tube 244 may be designed to slide into tube 228 and be secured in place by any suitable mechanism. Tube 228 may include, for example, a slot 256 that is aligned with a receiver 260 (such as a threaded receiver as can be seen in FIG. 9) in tube 244. When tube 244 is inserted over (or into, in the alternative) tube 228 to the desired extent, a screrv knob 264 or other securement mechanism can be used to maintain the connection at the desired point. In this way, the distance between the pusher and the stroller may be adjusted. In addition, optional distance markings 268 (as can be seen in FIG. 9) may be included so that different users can set a preferred distance. It will be understood that in the alternative tube 244 and tube 228 may be replaced by a single piece such that arm assembly 208 is formed of a uniform body.

[0026] Stroller handle connector 248 is designed and configured to be removably attached to the handle of a stroller. In a preferred embodiment, as best seen in FIG. 8, the attachment mechanism is a C-shape or half circle 252 that can snap over a stroller handle, which allows for convenient attachment and detachment as well as providing a safety break-away mechanism.

[0027] In an embodiment, an attachment for hands-free pushing of a pushable device includes a push arm assembly having a connector portion and a first tube, wherein the connector portion has a first side and an opposing side, wherein the first tube is coupled to the connector portion on the opposing side and projects away from the first side of the connector portion.
