Walker with a vertical extension for assisting a user in moving from a walking position to a more-erect position

Abstract

A walker with a vertical extension for assisting a user in moving from a walking position to a more-erect position is provided. In one embodiment, the vertical extension has secondary hand grips that can assist a user in standing more erect after being in a hunched-over position while using the walker. For example, the plurality of secondary hand grips can be arranged along the vertical extension to allow a user to climb the plurality of secondary hand grips to progressively stand more erect.

DETAILED DESCRIPTION

(13) By way of introduction, the below embodiments provide a walker with a vertical extension for assisting a user in moving from a walking position to a more-erect position. The vertical extension can be packaged together with the walker, such that the vertical extension and the walker are provided together to an end user (e.g., at the time of sale). In such a situation, the vertical extension can be integrated with or removably coupled with the walker (e.g., by the manufacturer, by a salesman, or by the end user). Alternatively, the vertical extension can be an accessory for an existing walker that can be purchased at the time of sale of the walker or later and coupled with the walker thereafter.

(14) Turning now to the drawings, FIGS. 1-6 show various views of a walker 10 of one embodiment. It should be understood that this is merely one implementation and other implementations can be used. As shown in the drawings, in this embodiment, the walker 10 comprises a frame 20 that carries several components found on typical walkers. More specifically, the frame 20 carries two rear wheels 34 and two larger front wheels 38, a pair of height-adjustable primary hand grips 40, each with a hand brake 45 coupled with a brake line 47, and a seat 50. The pair of hand grips 40 is referred to as the primary hand grips 40 because these are the hand grips that a user would use as he is walking with the walker 10. As such, the hand brakes 45 are arranged with the primary hand grips 40. It should be noted that various walkers can have different components, so the components, shapes, and arrangements shown in these drawings are not necessarily required. For example, some walkers may only have front wheels (and no rear wheels), while other walkers may not have any wheels at all. Also, some walkers may not have a seat or brakes but may have other components not shown in these drawings. Accordingly, the term walker as used herein generally refers to a mobility-assistance device and does not require any specific components shown or described herein.

(15) In this embodiment, a vertical extension 60 is coupled with the frame 20 of the walker 10. As used herein, the phrase coupled with can mean directly coupled with or indirectly coupled with through one or more components, named or unnamed herein. Here, the vertical extension 60 is removably coupled with the frame 20 via an attachment mechanism. In this embodiment, the attachment mechanism comprises front and rear plates 65, 67 that mount to either side of left and right arms of the frame 20 and are secured by a bolt 68 and nut 69. Of course, this is just one particular example of an attachment mechanism, and other types of attachment mechanisms can be used. Also, as noted above, in other embodiments, the vertical extension 60 can be integrated with the frame 20 (such as when both components are manufactured together or are separate components that are welded, glued, or otherwise secured in a permanent or semi-permanent basis).

(16) In this embodiment, the vertical extension 60 comprises a structure with two sides and a top that generally form an upside-down U-shape, which provide stability to the vertical extension 60 when it is used by a user. A plurality of pairs of secondary hand grips 70, 80, 90 positioned along the two sides of the structure above the primary hand grips 40. These hand grips 70, 80, 90 are referred to as secondary because they would not typically be used by a user as he is walking with the walker 10. Because of this, the hand brakes 45 are arranged with the primary hand grips 40 and not with the secondary hand grips 70, 80, 90. Some or all of the secondary hand grips 70, 80, 90 can be at fixed positions or by height adjustable.

(17) Here, the plurality of secondary hand grips 70, 80, 90 takes the form of a plurality of parallel pairs of hand grips (i.e., two secondary hand grips in the same horizontal plane) arranged along the vertical extension 60 to allow a user to climb the plurality of secondary hand grips to progressively stand more upright. It should be understood that the plurality of secondary hand grips can be arranged in any suitable fashion. For example, the secondary hand grips can be arranged in a staggered (instead of parallel) manner (i.e., only one secondary hand grip in a horizontal plane), as shown in FIG. 3B. Also, it should be understood that a secondary hand grip is positioned above the primary hand grips when the secondary hand grip is directly above (i.e., in the same vertical plane as) or indirectly above (i.e., in a different vertical plane as) the primary hand grips 40. Also, the number of secondary hang grips can vary and be more than or fewer than what is shown in the drawings.

(18) Returning to the drawings, FIG. 8 shows the walker 10 being used by a user. As shown in FIG. 8, the user is slightly hunched over when using the walker 10. For some users, it may be difficult to stand more erect after being in a hunched-over position for a period of time. For example, a user's back muscles may tighten while being hunched over, creating a resistance to the user standing more erect. As shown in FIGS. 9-12, the vertical extension 60 of these embodiments can assist the user in moving from the hunched-over walking position to a more-erect position. The term more erect is used instead of erect as it is recognized that, for some users, it may be very difficult or impossible for them to stand completely erect.

(19) In FIG. 9, the user is shown in the hunched-over walking position, holding onto the primary pair of hand grips 40. In this position, the user is angled about 220 degrees (this and the below measurements are used merely for illustration purposes and may not be the actual angles encountered by users). To assist the user in moving from the hunched-over walking position to a more-erect position, the user can climb the secondary hand grips on the vertical extension 60. FIGS. 10-12 show that when the user climbs the first, second, and third pairs of secondary hand grips 70, 80, 90, respectively, the user is able to stand more and more erect. In this example, the angle at which the user is hunched over progressively decreases from 220 degrees to 210 degrees to 195 degrees and then to 180 degrees as the user climbs the first, second, and third pairs of secondary hand grips 70, 80, 90.

(20) As noted above, some prior walkers have upper and lower pairs of hand grips. However, the lower pair of hand grips in prior walkers is used merely to assist a user from moving from a seated position to a walking position, and the upper pair of hand grips is used for walking (which is why the hand brakes are arranged next to the upper pair of hand grips instead of the lower pair of hand grips). In contrast, with the walker 10 of this embodiment, the lower pair of hand grips 40 is used for walking (which is why the hand brakes 45 are arranged next to them), and the upper pairs 70, 80, 90 are used to assist a user from moving from a walking position to a more-erect position (not from a seated position to a walking position).

(21) It is intended that the foregoing detailed description be understood as an illustration of selected forms that the invention can take and not as a definition of the invention. It is only the following claims, including all equivalents, that are intended to define the scope of the claimed invention. Finally, it should be noted that any aspect of any of the embodiments described herein can be used alone or in combination with one another.
