GLIDE FOR WALKER LEG
A glide for walker leg includes a seat including a bottom cavity; a base on the seat and including a hole and a top groove; a hollow first sliding member adapted to mount on the base and including a first bore, a bottom rail slidably inserted into the groove, and a top first slope; a hollow second sliding member including a bottom second slope adapted to matingly, slidably mount on the first slope, a second bore, and an upper threaded section in the second bore; and a threaded fastener adapted to insert through the cavity, the hole, the first and second bores for threadedly securing to the threaded section. Driving the fastener will slide the second sliding member relative to the first sliding member by sliding the rail in the groove so as to urge the first and second sliding members against an inner wall of the leg.
1. Field of Invention
The present invention relates to walker legs and more particularly to such legs having characteristics including increased stability by attaching to an improved glide.
2. Related Art
A great variety of walkers are available for assisting the lame or the convalescent. Conventionally, a walker is made of metal tubes and comprises a plurality of plastic glides (e.g., ski glides or the like) each attached to the leg thereof.
A conventional walker is shown in
However, the prior art suffered from a disadvantage. For example, the fastening of the leg A in the bore E may be compromised after a short period time of use due to poor quality and/or bore expansion or contraction caused by temperature change. Thus, the need for improvement still exists.
SUMMARY OF THE INVENTIONIt is therefore an object of the present invention to provide a detachable glide adapted to mount in a hollow leg of a walker.
It is another object of the present invention to provide a glide adapted to quickly detach from a hollow leg of a walker and attach thereto after replacing with a different one.
In one aspect of the present invention the glide can be either attached to the leg by threadely securing its fastener thereto or detached therefrom by unfastening the fastener.
In another aspect of the present invention driving the fastener will slide two sliding members of the glide to urge against an inner wall of the leg for fastening the glide and the leg together.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
Referring to
The seat 10 is implemented as ski glide which is designed for easy sliding over snow. But other types of seat are possible in other embodiments. The seat 10 comprises a cavity 11 on its bottom. The base 20 comprises a longitudinal hole 21 in communication with the cavity 11, a top disc 22, and a transverse groove 23 formed on the disc 22 having a length equal to a diameter of the disc 22. A top of the hole 21 is formed at a center of the groove 23.
The first sliding member 30 is of hollow cylinder and comprises two opposite rails 32 formed on a bottom 31, a top slope 33, and a bore 34. The second sliding member 40 is also of hollow cylinder and comprises a bottom slope 43 shaped to matingly engage with the top slope 33, a bore 41, and a threaded section 42 formed on an upper portion of the bore 41. The fastener 50 is implemented as a screw and comprises a head 51 and a thread 52.

Referring to
Note that each of the first sliding member 30 and the second sliding member 40 may have other shapes other than above (i.e., cylinder). Also, the bore 34 may have a section of other shape other than circle as shown above as long as the sliding of the first sliding member 30 relative to the base 20 is not hindered by, for example, the thread 52. Moreover, the glide of the invention may be attached to the leg of an object other than walker without departing from the spirit of the invention.
While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
Claims
1. A glide mountable in a hollow leg of a device comprising: a second bore, and a threaded section formed in an upper portion of the second bore; and
- a seat including a bottom cavity;
- a base formed on the seat and including a longitudinal hole in communication with the cavity, and a top first mating member;
- a hollow post-like first sliding member adapted to mount on the base and including a first bore, a bottom second mating member adapted to slidably insert into the first mating member, and a top first slope;
- a hollow post-like second sliding member including a bottom second slope adapted to matingly, slidably mount on the first sliding member,
- a fastener including a thread and adapted to insert through the cavity, the hole, the first bore, and the second bore for threadedly securing the thread to the threaded section;
- whereby driving the fastener will slide the second sliding member relative to the first sliding member by sliding the second mating member in the first mating member, laterally move the second sliding member in a first direction to urge against an inner wall of the leg, and laterally move the first sliding member in a second opposite direction to urge against the inner wall of the leg until the fastener is stopped by a shoulder formed between the cavity and the hole.
2. The glide of claim 1, wherein the first mating member is a groove.
3. The glide of claim 2, wherein the second mating member is a rail adapted to slidably insert into the groove.
4. The glide of claim 1, wherein the second slope is adapted to matingly, slidably mount on the first slope of the first sliding member.
