Abstract
The described device demonstrates an apparatus and method for a collapsible wheeled walker or rollator that includes a pair of height adjustable armrests or supports. The armrests may be selectively articulated about hinge or pivot attached to a support tube. The articulating armrest may be locked into a stationary position via a locking pin for use as a typical standing rollator. Alternatively, the armrests are articulable about a hinge when the locking pin is removed, where a damper is interconnected between the hinge and a handle tube attached to the armrests to provide resistance to the movement of the armrests allowing a user to exercise arm muscles while using the wheeled walker. As such the disclosed device operates as both a wheeled walker and an exercise mechanism for the user's arms and upper body.

DETAILED DESCRIPTION
[0024] The detailed description set forth below in connection with the appended drawings is intended as a description of certain embodiments of a wheeled walker with articulating exercise support arms with resistance of movement and/or related method and is not intended to represent the only forms that may be developed or utilized. The description sets forth the various structure and/or functions in connection with the illustrated embodiments, but it is to be understood, however, that the same or equivalent structure and/or functions may be accomplished by different embodiments that are also intended to be encompassed within the scope of the present disclosure. It is further understood that the use of relational terms such as first and second, and the like are used solely to distinguish one entity from another without necessarily requiring or implying any actual such relationship or order between such entities.
[0025] The background, summary and the above description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed inventive subject matter, or that any publication specifically or implicitly referenced is prior art.
[0026] In some embodiments, the numbers expressing dimensions, quantities, quantiles of ingredients, properties of materials, and so forth, used to describe and claim certain embodiments of the disclosure are to be understood as being modified in some instances by the term “about.” Accordingly, in some embodiments, the numerical parameters set forth in the written description and attached claims are approximations that can vary depending upon the desired properties sought to be obtained by a particular embodiment. In some embodiments, the numerical parameters should be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of some embodiments of the disclosure are approximations, the numerical values set forth in the specific examples are reported as precisely as practicable. The numerical values presented in some embodiments of the disclose may contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.
[0027] As used in the description herein and throughout the claims that follow, the meaning of “a,” “an,” and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.
[0028] As used herein, and unless the context dictates otherwise, the term “coupled to” is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “coupled to” and “coupled with” are used synonymously.
[0029] Unless the context dictates the contrary, all ranges set forth herein should be interpreted as being inclusive of their endpoints, and open-ended ranges should be interpreted to include commercially practical values. Similarly, all lists of values should be considered as inclusive of intermediate values unless the context indicates the contrary.
[0030] The recitation of ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate value falling within the range. Unless otherwise indicated herein, each individual value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g. “such as”) provided with respect to certain embodiments herein is intended merely to better illuminate the disclosure and does not pose a limitation on the scope of the claimed inventive subject matter. No language in the specification should be construed as indicating any non-claimed element essential to the practice of the inventive subject matter.
[0031] Groupings of alternative elements or embodiments of the inventive subject matter disclosed herein are not to be construed as limitations. Each group member can be referred to and claimed individually or in any combination with other members of the group or other elements found herein. One or more members of a group can be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all Markush groups used in the appended claims.
[0032] The following discussion provides many example embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed. Various objects, features, aspects and advantages of the inventive subject matter will become more apparent from the following detailed description of preferred embodiments, along with the accompanying drawing figures in which like numerals represent like components.
[0033] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the scope of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
[0034] Referring particularly to
[0035] A significant difference between the wheeled walker device of Fellingham II are the elements fixed to the top of height adjustment supports 46 and 48. Adjustable supports 46 and 48 are coupled to hinge assemblies 50 and 52, respectively. The hinge assemblies 50 and 52 are coupled to upper forks 54 and 56, respectively. Upper fork 54 is coupled to the left forearm rest 58 and the upper fork 56 is attached to right forearm rest 60. The forearm rests 58 and 60 are coupled to handle support tubes 62 and 64, respectively. The handle support tube 62 is formed to turn upwardly to define a handle 66. Likewise handle support tube 64 is formed to turn upwardly to define handle 68. Handles 66 and 68 are each coupled to hand brake levers 70 and 72. A tube damper 74 is attached between a lower fork 78, pivotally between the fork members of the lower fork 78 and pivotally attached to an attachment member 82 coupled to the handle support tube 62. Likewise, a tube damper 76 is attached between a lower fork 80, pivotally between fork members of the lower fork 80 and pivotally attached to an attachment member 84 coupled to the handle support tube 64.

[0039] Referring particularly to
[0040] The upper fork 56 includes hinge pin apertures 136A and 136B formed into the downward extending prongs of the upper fork 56. Above each of the hinge pin apertures 136A and 136B there are formed locking pin openings 138A and 138B. The hinge assembly 52 also includes hinge pin apertures 140A and 140B and locking pin apertures 142A and 142B. The hinge assembly also includes an opening 144 to provide a passage for the brake cable 132 and is shaped to work cooperatively with the other components openings to avoid pinching, bending or fatiguing a brake cable 134. The hinge assembly 52 also includes an internal opening 146 to allow the passage of the brake cable 132 into the adjustable support tube 48. In assembly, upper fork 56 is received over the hinge assembly 52 to align the hinge pin apertures 136A-B and hinge pin apertures 140A-B. In alignment, both hinge pin apertures 136A-B and hinge pin apertures 140A-B receive a hinge pin 48 that is secured in place hinge pin retainers 150 and 152. The hinge pin 148 includes recesses 154 and 156 to receive retainers 150 and 154 respectively. The recesses are 154 and 156 are off-set from the center of the hinge pin 148 to keep the hinge pin 148 in a preferred orientation. As such, with the turning of the upper fork 56 about the hinge assembly 52, the hinge pin 148 remains in an orientation that allows openings 158 and 160 to maintain a generally vertical passage through the hinge pin 148 to allow the passage of the brake cable 132 without the cable 132 being bent or otherwise fatigued. The brake cable passage 132 is shown in
[0041] When a user wishes to stop the rotation of the armrest 60 about the hinge pin 148, a locking pin 88 is provided to be inserted into openings 138A, 142A, 142B and 138B. The locking pin prevents rotation and freezes the joint comprising the hinge assembly 52 and the upper fork 56 from rotating. The locking pin 88 may be an elongate member 162 having enough length to pass through the hinge assembly 52 and upper fork 56. The locking pin 88 may have a grasping ring 164 formed on the end of the member 162 to allow a user to easily grasp the locking pin 88. A string or chord (not shown) may be attached to the ring 164, which is attached to the part of the device 12 to prevent loss of the locking pin 88. The locking pin 88 may also have a spring-loaded ball 166 formed toward the end of member 162 which is pushed in during insertion through the various apertures, and springs out when the member 162 has passed through the members. Locking pin 86 has identical construction.
