1. Field of the Invention
The present invention relates to a sole, and more particularly to a sole for rehabilitation footwear that can provide a preferred rehabilitation effect to a patient.
2. Description of Related Art
Conventional rehabilitation footwear has a sole, a supporting frame and multiple fastening belts. The sole has a body and a shock-absorbing layer. The body has a flat bottom. The shock-absorbing layer is securely mounted on the flat bottom of the body to fully abut the ground. The supporting frame is connected to the body of the sole to support the leg of a patient. The fastening belts are connected to the body of the sole and the supporting frame to hold the patient's leg and foot with the conventional rehabilitation footwear.
However, the conventional rehabilitation footwear can provide a protecting and rehabilitating effect to the patient's injured leg and foot. When the patent uses the conventional rehabilitation footwear and walks, a front end of the shock-absorbing layer may be lifted off by the friction with the ground due to the shock-absorbing layer is mounted on the flat bottom of the body of the sole. When the shock-absorbing layer is lifted, the patient may be got a secondary hurt by the raising shock-absorbing layer and this is unsafe in use.
The present invention provides a sole for rehabilitation footwear to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a sole for rehabilitation footwear that can provide a preferred rehabilitation effect to a patient.
The sole for rehabilitation footwear in accordance with the present invention has a body and a shock-absorbing layer. The body has a connecting frame and a holding groove. The holding groove is formed in a bottom of the body along a periphery of the body between the connecting frame and a bottom surface of the bottom of the body. The shock-absorbing layer is connected to the body and has a mounting flange. The mounting flange is annularly formed on and protrudes from a top surface of the shock-absorbing layer along a periphery of the shock-absorbing layer and is mounted in the holding groove of the body.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
The body 10 has a rear end, a front end, a top surface, a periphery, a bottom, a mounting recess 11, an air cushion 12, a pad 13, a connecting frame 14 and a holding groove 15. With reference to
The pad 13 is mounted on the top surface of the body 10 to cover the air cushion 12. The connecting frame 14 is formed on and protrudes upwardly from the top surface of the body along the periphery of the body 10. The holding groove 15 is formed in the bottom of the body 10 along the periphery of the body 10 between the connecting frame 14 and a bottom surface of the bottom of the body 10.
The shock-absorbing layer 20 is connected to the body 10 and has a top surface, a bottom surface, a periphery, a mounting flange 21, multiple skidproof protrusions 22 and multiple sucking protrusions 23. The top surface of the shock-absorbing layer 20 abuts the bottom face of the bottom of the body 10. With reference to
The skidproof protrusions 22 are formed on and protrude from the bottom surface of the shock-absorbing layer 20 at intervals. Preferably, the intervals between the skidproof protrusions 22 are the same. The sucking protrusions 23 are formed on and protrude from the bottom surface of the shock-absorbing layer 20 between the skidproof protrusions 22. In addition, each one of the sucking protrusions 23 has a curved bottom surface to enable the sucking protrusion 23 to have a sucking effect to the shock-absorbing layer 20 when the sucking protrusion 23 abuts the ground.
In use, with reference to
When the patient walks on the ground with the rehabilitation footwear, the front end of the body 10 is curved upwardly with an angle θ relative to the ground and this can prevent the shock-absorbing layer 20 from abutting against the ground at the front end of the body 10. Then, the shock-absorbing layer 20 can be securely mounted on the body 10 without raising by the ground and this can avoid the patient getting a secondary hurt.
Furthermore, the mounting flange 21 is inserted into and is mounted in the holding groove 15 of the body 10 to enable the shock-absorbing layer 20 to mount securely on the body 10, and this can prevent the shock-absorbing layer 20 from raising when abuts against the ground at the front end of the body 10. Additionally, in assembly, the inserting type of the mounting flange 21 can enable the shock-absorbing layer 20 to align with the body 10 easily.
In addition, the adhesive face that is defined between the top surface of the shock-absorbing layer 20 and an inner surface of the mounting flange 21 can be used to increase the connecting area between the body 10 and the shock-absorbing layer 20, and this can increase the connecting strength between the body 10 and the shock-absorbing layer 20.
Additionally, the skidproof protrusions 22 of the shock-absorbing layer 20 can provide a skidproof effect to the rehabilitation footwear and this can enable the patient to walk safely. Moreover, the sucking protrusions 23 of the shock-absorbing layer 20 also can a skidproof effect to the rehabilitation footwear and this can enable the patient to walk safely.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
