1. Technical Field
This disclosure relates generally to medical devices, and more particularly to crutches.
2. Background Art
Crutches have been used for centuries during rehabilitation of injuries to hips and legs. For example, when a leg is broken or an ankle is sprained, a person may use one or two crutches while the leg or ankle heals.
While crutches have been used for a long time, and while some of the materials used to make crutches have become stronger and lighter, the essential design, shape, and function of a crutch has not changed. A person uses a crutch to reduce the amount of weight loading an injured body portion. A person also uses a crutch to increase stability and balance when a lower limb or connecting part is injured or otherwise not available for mobility.
As the design of crutches has not varied for a long time, it would be advantageous to have an improved crutch design.
The accompanying figures, where like reference numerals refer to identical or functionally similar elements throughout the separate views and which together with the detailed description below are incorporated in and form part of the specification, serve to further illustrate various embodiments and to explain various principles and advantages all in accordance with the present disclosure.
Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of embodiments of the present disclosure.
Embodiments of the disclosure are now described in detail. Referring to the drawings, like numbers indicate like parts throughout the views. As used in the description herein and throughout the claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise: the meaning of “a,” “an,” and “the” includes plural reference, the meaning of “in” includes “in” and “on.” Relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, reference designators shown herein in parenthesis indicate components shown in a figure other than the one in discussion. For example, talking about a device (10) while discussing figure A would refer to an element, 10, shown in figure other than figure A.
Embodiments of the disclosure provide for an autographable crutch. In one embodiment, a crutch includes a marking receiving coating. As used herein, a “marking receiving coating” is a special coating configured to receive markings from a marking instrument where those markings dry quickly, are at least semi-permanent, and are not readily altered mechanically by, for example, smearing or smudging, unless otherwise designated in limited embodiments.
In one embodiment, the marking receiving coating at least partially covers the crutch. In one embodiment, the marking receiving coating covers the entire crutch. In another embodiment, where the crutch is manufactured from a particular material, such as wood or plastic, the marking receiving coating is disposed only on exposed portions of the material, i.e., exposed metal or exposed wood. In other embodiments, the marking receiving coating is selectively disposed along portions of the crutch to perform two functions: first, the marking receiving coating is to accept a marking from a marking instrument such as a pen, marker, or pencil. Second, the selective application of the marking receiving coating can impart an aesthetically pleasing appearance to the crutch. In yet other embodiments, the marking receiving coating can be selectively disposed on the crutch so as to indicate that the crutch is, in fact, an autographable crutch.
Autographable crutches configured in accordance with one or more embodiments of the disclosure provide numerous advantages over prior art crutches. A principle advantage is the providing the ability for a user of the crutch to receive autographs and get-well wishes from friends, family, and acquaintances. The disclosure contemplates that modern casts are fiberglass instead of plaster, and that fiberglass does not constitute a marking receiving coating as markings from markers and ink pens applied to fiberglass are slow to dry, impermanent, and smudge and smear easily. At the same time, the inventors have determined that friends, family, and acquaintances still desire to provide well wishes to those suffering from injury or other conditions requiring the use of medical devices in the form of markings. Embodiments of the disclosure advantageously provide a device to receive markings and display them so that received autographs and get-well wishes can be displayed during recovery.
In one embodiment, to create the autographable crutch, at least a portion of the crutch is coated with a marking receiving coating. The color of the coating can vary. For example, it can be a clear coating in one embodiment. In another embodiment, it can be a white coating. In another embodiment, it can be a colored coating, such as grey, red, blue, yellow, or green. In one embodiment, the marking receiving coating comprises a colored pigment selected to render markings disposed thereon visible to an onlooker. Once the marking receiving coating is disposed on at least portions of the crutch, markings from a marking instrument can be deposited on the marking receiving coating.
The marking receiving coating can be adapted to a predetermined marking to be received. For example, in one embodiment, the marking instrument is a marker. The marker can be indelible or non-permanent. The marking receiving coating can be adapted so that marker markings dry quickly and do not smudge. Similarly, in another embodiment, the marking instrument is an ink pen. Ink pens may use different inks from markers. Accordingly, the marking receiving coating can be adapted so that ink pen markings dry quickly and do not smudge. In yet another embodiment, the marking instrument can be a pencil. The marking receiving coating can be adapted so that pencil markings are at least semi-permanent and do not smudge readily. In yet another embodiment, the marking instrument can be chalk. The marking receiving coating can be adapted so that chalk markings are retained on the coating and do not erase easily.
In yet other embodiments, the user of the autographable crutch may want to continually reconfigure the crutch. Accordingly, in one embodiment the marking instrument may be a dry erase marker. The marking receiving coating can be adapted so that markings are easily erasable by making the coating glossy.

In one embodiment, the crutch 100 includes a substantially vertical, lower leg 101. The lower leg 101 can be covered with a slip-resistant tip 102 configured to increase a friction coefficient between the crutch 100 and a floor, street, or the ground.
An upper leg 103 extends from the lower leg 101. The upper leg 103 is disposed between lower portions of a pair of opposing vertical crutch columns 104,105. Each vertical crutch column 104,105 includes a plurality of sections. The sections include upper crutch sections 106,107, lower crutch sections 108,109, and leg coupling sections 110,111. In this illustrative embodiment, the lower crutch sections 108,109 are upwardly and outwardly inclined or curved as they extend from the leg coupling sections 110,111. The upper crutch sections 106,107 of this particular crutch 100 are substantially parallel, straight, and vertical.
The upper crutch sections 106,107 intersect a body-engaging beam 112 of the crutch 100. When the crutch 100 is in use, the body-engaging beam 112 is traditionally placed between the user's upper arm and torso beneath the armpit. The crutch 100 also includes a handgrip 113 that is disposed between the vertical crutch columns 104,105 between the upper crutch sections 106,107 and the lower crutch sections 108,109.

As shown, a marking receiving coating 202 is applied to at least partially cover the crutch 222. In one embodiment, the marking receiving coating 202 is to accept and/or receive a marking from a marking instrument as will be described below with reference to
In one embodiment, the marking receiving coating 202 comprises a matte finish. Other embodiments, such as the dry erase marker scenario described above, may employ a glossy, shiny, or smooth coating. However, in many embodiments, a matte finish is well suited to receiving markings from marking instruments and allowing those markings to dry quickly, be permanently or semi-permanently retained, and resist smearing or smudging.
As noted above, the marking receiving coating 202 can comprise various colors. For example, it can be a clear coating in one embodiment. In another embodiment, it can be a white coating. In another embodiment, it can be a colored coating, such as grey, red, blue, yellow, or green. In one embodiment, the marking receiving coating 202 comprises a colored pigment selected to render markings disposed thereon visible to an onlooker. Once the marking receiving coating 202 is disposed on at least portions of the crutch, markings from a marking instrument can be deposited on the marking receiving coating.
The marking receiving coating 202 applied can be adapted to a predetermined marking to be received. Additionally, the marking receiving coating 202 can be to receive a marking without smearing. For example, in one embodiment, the marking instrument is a marker. The marker can be indelible or non-permanent. The marking receiving coating 202 can be adapted so that marker markings dry quickly and do not smudge. Similarly, in another embodiment, the marking instrument is an ink pen. Ink pens may use different inks from markers. Accordingly, the marking receiving coating 202 can be adapted so that ink pen markings dry quickly and do not smudge. In yet another embodiment, the marking instrument can be a pencil. The marking receiving coating 202 can be adapted so that pencil markings are at least semi-permanent and do not smudge readily. In yet another embodiment, the marking instrument can be chalk. The marking receiving coating 202 can be adapted so that chalk markings are retained on the coating and do not erase easily.
The marking receiving coating 202 can be deposited on various portions, or alternatively the entirety, of the crutch 222. For example, in one embodiment the marking receiving coating 202 is disposed on the vertical crutch columns 204,205 of the crutch 222. In one embodiment, the marking receiving coating 202 is disposed only on portions of the vertical crutch columns 204,205. In another embodiment, the marking receiving coating 202 is disposed on an entirety of the vertical crutch columns 204,205. In another embodiment, the marking receiving coating 202 is disposed on the upper leg 203 of the crutch 222. In another embodiment, the marking receiving coating 202 is disposed on the lower leg 201 of the crutch 222. Of course, combinations of these can be used. For example, in one embodiment the marking receiving coating 202 is disposed on an entirety of the crutch 222. In yet another embodiment, where the crutch 222 is manufactured from a material such as wood, metal, fiberglass, carbon fiber, or other materials, the marking receiving coating 202 can be disposed on exposed portions of the material. Exposed portions would generally exclude portions disposed beneath the handgrip 213 or the body-engaging portion 212.
