Description

Durable sitting elastic body device

The present invention relates to an elastic cushion device, and more particularly to a durable sitting elastic cushion device.

Patients with ridge injuries often cannot easily change their posture due to inconvenient movement, and the ventilation effect of the seat or seat cushion is generally poor. After long-term sedentary, it will increase the patient's discomfort, and if it is serious, it may lead to hemorrhoids.

Therefore, the object of the present invention is to provide a durable sitting elastic body device which has a good ventilation effect and which is advantageous for changing the center of gravity of the ride.

Therefore, the novel durable sitting elastic body device comprises a seating unit and a gasket.

The seating unit includes a bottom layer, a top layer attached to the bottom layer and having a plurality of spaced apart openings, and a plurality of air cells spaced apart from the top surface of the top layer and surrounding the openings, respectively. Each air bag defines a gas chamber with the corresponding opening.

The spacer is disposed between the bottom layer and the top layer, and includes a plurality of flow blocking portions disposed between the bottom layer and the air chambers, and a plurality of connecting the adjacent flow blocking portions and sandwiching The bottom layer and the rib portion of the top layer.

The cross-sections of the baffles are circular in shape and do not completely obscure the openings. The baffles and the ribs cooperate to define a plurality of flow spaces in communication with the plenums.

The effect of the novel is that, by the characteristics of the airbags communicating with the flow spaces, when the user is sitting for a long time, the airbag located in the seating area can be squeezed through the weight of the body to change the degree of inflation of the airbags in different regions. Further, the center of gravity of the ride is changed, and the arrangement of the airbags allows the outside air to easily flow between the airbags, thereby achieving the effect of ventilation.

Other features and effects of the present invention will be apparent from the following description of the drawings, wherein: FIG. 1 is a perspective view showing an embodiment of the present type of durable sitting elastic body device; FIG. 2 is the embodiment. FIG. 3 is a partially enlarged perspective view showing a top layer of a seating unit of the embodiment; and FIG. 4 is a partially enlarged plan view showing a spacer of the embodiment.

Referring to FIGS. 1 through 4, an embodiment of the present type of durable sitting elastic body device includes a seating unit 2, a gasket 3, and an air inlet nozzle 4.

The seating unit 2 includes a bottom layer 21, a top layer 22 joined to the bottom layer 21 and having a plurality of spaced openings 221, and a plurality of air cells spaced apart from the top surface of the top layer 22 and surrounding the openings 221, respectively. 23, and four fixing holes 24 disposed at adjacent corners and extending through the bottom layer 21 and the top layer 22.

Each of the air cells 23 and the corresponding opening 221 define a plenum 231. In the present embodiment, the air cells 23 are made of liquid latex, and are elastic and suitable for the user to ride.

It is worth mentioning that the height of the airbags 23 affects the user's riding experience, depending on the needs.

The spacer 3 is sandwiched between the bottom layer 21 and the top layer 22, and includes a plurality of blocking portions 31 disposed between the bottom layer 21 and the air chambers 231, and a plurality of connecting adjacent ones. The flow blocking portion 31 is interposed between the bottom layer 21 and the rib portion 32 of the top layer 22.

The cross-sections of the blocking portions 31 are circular in shape and do not completely obscure the openings 221, and the blocking portions 31 and the rib portions 32 cooperate to define a plurality of flows communicating with the air chambers 231. Space 33.

In this embodiment, the openings 221 are approximately square, and any of the edges forms a lead angle. The diameter of the blocking portions 31 is equal to the length of the sides of the openings 221, but is not limited thereto.

In this embodiment, the width of the rib portions is tapered from the two ends toward the center, but is not limited thereto.

The air inlet nozzle 4 is disposed in one of the airbags 23 and communicates with the corresponding air chamber 231, and includes an extension 41 disposed on the airbag 23 and a gas valve 42 disposed at an end of the extension 41.

In actual use, the present invention is usually placed in a set (not shown), and then the user is allowed to ride on the user when the user is bent or When the pelvic cavity is deformed and the heights of the left and right halves are different, the lower part of the buttocks will be characterized by the elasticity of the material of the airbag 23 and the characteristics of the air chambers 231 communicating with the flow spaces 33. The partial air bag 23 is pressed, and the gas in the compressed air bag 23 is caused to flow through the flow spaces 33 to the air chamber 231 in the air bag 23 in other areas, so that the air bag 23 in other areas expands and supports the upper part of the buttocks. Achieve the effect of adjusting the position of the buttocks and avoid the pain and discomfort caused by direct contact of the hips with the seat.

In addition, patients with spinal cord injury have difficulty in changing their posture or soothing the muscles of the buttocks when riding in a wheelchair. This new type allows the patient to change the degree of expansion of the airbag 23 in different areas through the weight of the body, thereby easily changing the center of gravity during riding, and By the arrangement pattern of the airbags 23, the outside air is easily flown between the airbags 23, and the ventilation effect is achieved.

When the air bag 23 is to be inflated, the air valve 42 of the air inlet 4 is opened, and the air valve 42 is connected by using an air stick (not shown), and the air pump can be inflated by pulling the air stick. Acting, and the flow blocking portions 31 of the gasket 3 do not completely shield the characteristics of the air chambers 231, thereby achieving the effects of rapid inflation and deflation.

In summary, by the characteristics of the airbags 23 communicating with the flow spaces 33, the user can easily change the degree of expansion of the airbags 23 in different regions when riding, so as to achieve the effect of changing the center of gravity of the ride, and the airbags The arrangement of 23 has the advantage of ventilation, so it can achieve the purpose of the present invention.

However, the above is only an embodiment of the present invention, and it is not possible to limit the scope of the implementation of the present invention. The simple equivalent changes and modifications made by the scope of the patent and the contents of the patent specification are still within the scope of this new patent.
