BACKGROUND
1. Technical Field
This invention relates, generally, to apparatus carrying and supporting containers of various sizes and shapes. In particular, this invention relates to apparatus which can be attached to walkers, wheelchairs, strollers and the like for carrying and supporting drink containers, such as cans, cups, drinking glasses and the like.
Individuals with infirmities, injuries, advanced age, or other disabilities commonly use assist devices for walking. A device “walker” is an example of an assist device used to steady the user's balance when walking. Walkers come in various sizes and shapes, and some with wheels, and others have seats to sit on and rest. The term “walker” as used herein, includes conventional walkers and wheeled walkers, such as “rollators” and the like. “Rollator” is believed to be a trade name for an assist device that consists of a frame with three or four wheels, handlebars and a built-in seat, which allows the user to stop and rest when needed. Rollators can be equipped with a shopping basket. Rollators are typically more sophisticated than conventional walkers with wheels. The handlebars are equipped with hand brakes that can be lifted or pushed downward to instantly stop the rollator. With individuals that cannot safely walk on their own, assist devices, such as wheelchairs, strollers and buggies are used. The structural frames of these devices typically comprise lightweight tubing of various sizes, arranged in trusses and other configurations. These devices must not have protruding portions and must have a size and shape enabling safe navigation of tight spaces and avoiding snaring objects and structures. The frames of these devices are shaped to create an interior space that the user may walk or sit in. These interior spaces must not be permanently obstructed for that space to remain useful.
When using walkers, it is necessary, at times, to carry various size and shapes of containers for liquids and solids, such as a water bottle, canned drink, baby bottle, coffee cup, ice cream cup, and the like. Since safely operating these devices usually occupies one or both hands, a need exists to provide a hands free means for carrying a container. It is essential that the carrier, when installed, not create obstructions to use or mobility. Additionally, the carrier should preferably have a simple construction that is durable and inexpensive to manufacture. Due to the variety of structural designs of these devices, a container carrying means ideally must have multiple mounting options. It is preferable that the carrier accommodate various container sizes and shapes.
2. Background Art
Prior art container carriers exist in the market that can be attached to walkers and other assist devices. These carriers were designed to accommodate a variety of frame sizes and shapes and drink sizes and shapes but, when installed on the exterior of the walker, have increased the width and decreased the mobility of the walker. When installed on the interior, these prior art carriers have obstructed the interior space provided for the user to sit and stand. These devices have been expensive to manufacture.
Accordingly, there is a need for a container carrier that is easy to install and inexpensive to manufacture and does not decrease the usable, interior space of the device or permanently obstruct its interior space.

DETAILED DESCRIPTION OF THE INVENTIONS
Referring now to the drawings, wherein like or corresponding parts are designated by like or corresponding reference numbers throughout the several views, there is illustrated in FIG. 1, an embodiment of the container carrier 10 removably installed on the inclined frame leg L of a rollator type walker. This particular walker configuration is of the type that has a tubular truss frame F, wheels W, a seat S, and handles (not shown) for the user to grasp. As illustrated in FIG. 1, the carrier 10 includes a base 20 for supporting a container and a stabilizing ring assembly 30.
The details of the construction of the carrier 10 will be described by referring to FIGS. 2-7. It can be seen in that the carrier 10 comprises a few basic structural elements, including, the base 20, stabilizing ring 30, U-shaped brackets 40, the mounting flange 50, flange 60, reducer pivot flange 70 and reducer 80. As illustrated, these elements are assembled into two subassemblies pivotally connected together. The first subassembly comprising: mounting flange 50 and U-shaped brackets 40. The second subassembly comprising: base 20, stabilizing ring 30, flange 60, reducer pivot flange 70 and reducer 80. These structural elements are formed from a plastic sheet material, such as high density polyethylene (HDPE).
The flanges 50, 60 and 70 span the distance between the base 20 and stabilizer ring 30. Flange 60 and reducer pivot flange 70 have their upper and lower ends connected to base 20 and stabilizing ring 30. As illustrated in FIG. 4, recessed screws 59 extend through stabilizer ring 30 and are threaded into the flange 60. Flange 70 is captured by recessed pockets in the base 20 and stabilizer ring 30 reducing material costs and assembly time. Similar recessed screws (not shown) extend through the base 20 and into the flanges 60 and 70.
As illustrated in FIGS. 2, 4 and 5, base 20 has a generally horizontally extending circular portion with an outer radius R. Base 20 is necked down to a width N adjacent the circular portion. The shape of the sides of the neck portion provides clearance for leg L of the carrier 10 when the carrier 10 is rotated to the interior position, illustrated in FIG. 5. A recess 22 is formed in the base for receiving and stabilizing the bottoms of containers (not shown). A central drain hole 24 is present to prevent the buildup of liquid in the recess R.
As illustrated in FIGS. 4 and 5, stabilizing ring 30 has a generally circular opening 32 with an inner radius R2 extending there through. The opening 32 is centered over the recess 22 in base 20. Stabilizer ring 30 is broken or is discontinuous on one side to form a gap G to accommodate the handles of drink containers, such as mugs and coffee cups.
The costs of fabricating the carrier is reduced by allowing the base 20 to be formed in part from the scrap created by machining the stabilizing ring from sheet material. As long as the Radius R is less than the radius R2 and the gap G is larger than the neck N, the center removed from the stabilizing ring 30 can be used to form the base 20.
Details of the structure of mounting flange 50 and the U-shaped bracket 40 are best illustrated in FIGS. 6, 7A and 7B. As illustrated in these figures, flange 50 is generally rectangular shaped and in this embodiment is provided with a plurality of countersunk bores 52, 54 and 56. By providing a plurality of pre-drilled bores arranged in various configurations allows the carrier 10 to be mounted on tubular structure members extending at various angles. In FIG. 7A, the carrier 10 is illustrated using U-shaped bracket 40 to clamp around an inclined structural member, such as leg L of a walker. In FIG. 7B, U-shaped bracket 40 is shown clamped around a vertical leg L2. In FIGS. 6 and 7A, screws 42 are illustrated extending through bores 52 and 54 and are threaded into the legs of the U-shaped bracket 40. These screws, when tightened, clamp the structural member between the U-shaped bracket 40 and the mounting flange 50. In FIG. 7B, the bracket 40 is attached to the flange 50 through bores 52 and 56. Although only three predrilled bores are illustrated in these figures, is appreciated that more bores at different angles in configurations could be present in the mounting flange to accommodate attachment to a variety of different devices. It also should be appreciated that a plurality of different U-shaped brackets 40 could be supplied with the carrier to accommodate attachment to a variety of shapes and sizes of structural elements.
A vertically extending pivot axis 58 allows the container holding portion of the carrier 10 to pivot between the positions illustrated in FIGS. 4 and 5. The pivot 58 extends through the mounting flange 50, base 20 and stabilizing ring 30. Pivot 58 allows the carrier 10 to be mounted on the exterior E of the walker or other device as illustrated in FIGS. 1 and 4, out of the interior I of the device so that it does not inhibit use of the interior I of the device. For example, if a user is resting on the seat S of a walker or the like, the carrier is assessable yet out of the way. In FIG. 5, the carrier 10 is illustrated rotated about pivot 58 in the direction of the interior I of the walker. With the carrier 10 rotated into the interior, the walker can be used and moved through doorways or other tight spaces without interference from the carrier 10.
Another feature of the carrier 10 is that cylindrical shaped magnets 62 are embedded in flanges 50 and 60. As illustrated in FIG. 6, the magnets 62 are positioned so that when the carrier is in the position illustrated in FIGS. 2 and 4, the magnets 62 in the two flanges or aligned and in contact. It should be appreciated that the forces of magnetic attraction between the magnets 62 tend to releasably hold the container carrier 10 in the extended position but allows the carrier 10 to be rotated to the retracted position in the interior of the walker by overcoming the magnetic forces. As can be seen in the figures, the shape of the exterior of the base allows the container carrier to rotate into the interior of the walker without interfering with the walker's frame. In this manner, all or substantially all of the base will rotate into the interior of the walker, in a position out of the way.
An additional feature of the carrier 10 is that it accommodates containers of various sizes and shapes. As previously pointed out, the gap G in the support ring 30 provides a clearance for containers with handles, such as coffee cups and mugs. In addition, the containers of various sizes are accommodated by utilizing a pivoting reducer 80. The reducer 80 has a bifurcated end 82 which is pivotally attached to the reducer pivot flange 70 by horizontally extending pivot 72. As illustrated, reducer 80 pivots between horizontal position adjacent to the stabilizer where it can engage and stabilize a smaller container and a vertically extending position when out of use. The magnetic forces of aligned magnets 84 embedded in stabilizing ring 30 and reducer 80 releasably tend to hold the reducer 80 in the position illustrated in FIG. 2.
While the preceding description contains many specificities, however, it is to be understood that same are presented only to describe some of the presently preferred embodiments of the invention, and not by way of limitation. Changes can be made to various aspects of the invention, without departing from the scope thereof.
Therefore, the scope of the invention is not to be limited to the illustrative examples set forth above, but encompasses modifications which may become apparent to those of ordinary skill in the relevant art.
