Abstract

An air cushion has a body and a supporting cushion. The supporting cushion is mounted inside of the body and has multiple hexagon-shaped holes. The holes are formed through the supporting cushion and construct as a hive structure. The hive structure is able to provide an excellent supporting effect to make a person's feet comfortable.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to an air cushion, and more particularly to an air cushion with a hive structure that is able to provide an excellent supporting effect.
  • 2. Description of Related Art
  • With reference to FIGS. 6 and 7, a conventional air cushion is mounted on a bottom of a shoe and comprises a housing (30), an upper cushion (31), a center cushion (32), a spring (33), a lower cushion (34) and two air valve pipes (35). The center cushion (32) has a bottom surface and a spring recess (321). The spring recess (321) is formed on the bottom surface of the center cushion (32).
  • The lower cushion (34) has a top surface and a spring recess (341). The spring recess (341) is formed on the top surface of the lower cushion (34).
  • The spring (33) is mounted between the spring recesses (321) of the center cushion (32) and the lower cushion (34).
  • The housing (30) covers the upper cushion (31), the center cushion (32), the spring (33) and the lower cushion (34) and has a side.
  • The two valve pipes (35) are mounted at side of the housing (30).
  • When the spring (33) is pressed, force applied from the ground can be eliminated to protect a person's feet. However, the spring (33) also presses against the housing (30) so that the spring (33) will stab through the housing (30) to inject the person's feet.
  • Furthermore, the spring (33) does not have an enough supporting effect to support the person's weight. The person is easy to feel uncomfortable, when the person wears a shoe with the conventional air cushion.
  • To overcome the shortcomings, the present invention provides an air cushion to obviate or mitigate the aforementioned problems.
    • SUMMARY OF THE INVENTION
  • The primary objective of the present invention is to provide an air cushion that has an excellent supporting effect.
  • The air cushion has a body and a supporting cushion. The supporting cushion is mounted inside of the body and has multiple hexagon-shaped holes. The holes are formed through the supporting cushion and construct as a hive structure. The hive structure is able to provide the supporting cushion an excellent supporting effect to make a person's feet comfortable. The air cushion does not need any spring to absorb force occurring by a person stepping so that the person's feet will not be injected.
  • 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.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective view of an air cushion in accordance with the present invention;
  • FIG. 2 is another perspective view of the air cushion in FIG. 1;
  • FIG. 3 is a cross sectional side view of the air cushion in FIG. 1;
  • FIG. 4 is a cross sectional side view of the air cushion in FIG. 1 mounted on a bottom of a shoe;
  • FIG. 5 is a top cross sectional side view of the air cushion mounted on a bottom of a shoe in FIG. 4;
  • FIG. 6 is an exploded perspective view of a conventional air cushion in accordance with the prior art; and
  • FIG. 7 is a perspective view of the conventional air cushion in FIG. 6.
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • With reference to FIGS. 1, 2, 3 and 4, an air cushion for a shoe in accordance with the present invention comprises a body (10) and a supporting cushion (20).
  • The body (10) is hollow and flat and has an air chamber (11), a side, an air-entering device (12) and an air-discharging device (13). The air chamber (11) is defined inside of the body (10).
  • The air-entering device (12) has a pipe (121) and a check valve (122). The pipe (121) has a distal opening and a proximal opening. The proximal opening of the pipe (121) is mounted at the side of the body (10) and communicates with the air chamber (11) in the body (10). The check valve (122) is mounted at the distal end of the pipe (121) to allow air enter the air chamber (11) of the body (10) from environment.
  • The air-discharging device (13) has a pipe (131) and a check valve (132). The pipe (131) has a distal opening and a proximal opening. The proximal opening of the pipe (131) is mounted at the side of the body (10) and communicates with the air chamber (11) of the body (10). The check valve (132) is mounted at the distal end of the pipe (131) to allow air to exhaust out of the air chamber (11) in the body (10).
  • The supporting cushion (20) is a resilient block and has multiple hexagon-shaped holes (21). The holes (21) are formed through the supporting cushion (20) and construct as a hive structure.
  • With reference to FIGS. 4 and 5, the air cushion is mounted a bottom of a shoe. When a person wears the shoe, the supporting cushion (20) and the body (10) will be deformed. With the deformation of the supporting cushion (20), the force applied by the user wearing the shoe is absorbed. The air in the air chamber (11) of the body (10) exhausts through the air-discharging device (13). When the force is released, the air-entering device (12) inhales the air into air chamber (11) in the body (10). The supporting cushion (20) and the body (10) return back to original shapes.
  • The hive structure is able to provide an excellent supporting effect to make the person's feet more comfortable. Furthermore, the air cushion does not have any spring so that the person's feet will not be injected.
  • 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 function of the invention, the disclosure is illustrative only. Changes may be made in detail 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.
