BACKGROUND

a. Field of the Invention

The present invention relates to a seat pad, and particularly to an auxiliary seat pad on a toilet, a stool and a chair to assist seating for an invalid with less strength, safety and comfort.

b. Related Art Conventional raised toilet seats have been invented as an auxiliary for an invalid whom is difficult to use an ordinary toilet, with which an invalid can get up and sit down with less strength. For examples of some of such prior invention are shown in patents to Locamo, U.S. patent No. 5027445; Locamo, U.S. patent No. 5199112; Hunt, U.S. patent No. D489438. However, they were made in a rigid material, which were uncomfortable and dangerous for an invalid to use in a slippery bathroom.

There were also some prior arts of the cushioned seat invented for a soft and comfortable toilet seat as shown in patents to Ginsburg, U.S. patent No. 3949432; Ginsburg, U.S. patent No. 4248646; Hicks, U.S. patent No. D390644; Wang, U.S. patent No. 5991935; Orgias, U.S. patent No. 6330723; White, U.S. patent No. 6370704. The conventional cushioned toilet seats are formed of three layers: a base; an insert disposed on the top surface of the base; and an outer cover layer affixed to the base. Basically they are invented for a normal user. Therefore, they are emphasized on the softness and comfort, for which doesn't suit for an invalid whom asks for a safe and strength less seat.

Considering the above arts, the present invention of an auxiliary seat pad can benefit for an invalid to sit with less strength, safety and comfort.

SUMMARY OF THE INVENTION

Briefly described according to the first preferred embodiment of the present invention, an auxiliary seat pad comprises a support plate, a stuffing body, an enclosed body, and a set of the clamping apparatus. The detail description of each part of said auxiliary seat pad is as following: A support plate is a rigid annular plate as a base to stand the weight of an invalid, and join with a set of the clamping apparatus.

A stuffing body is modeled a thick light stuff and disposed on said support plate, with which form offers to raise up the surface of sitting part for an invalid to sit and bend his /her knee with less strength.

An enclosed body is a foamed elastic stuff to enclose said support plate and said stuffing body with a ventilated texture on the surface, with which the gooseflesh-like texture offers a dry and skid proof contacts for an invalid, and which is preferably made from a waterproof material which is convenient for washing and cleaning. An inner peripheral flange of said enclosed body inserts to said toilet bowl.

The density of a stuffing body is relatively opposite to an enclosed body, for example, a lower dense stuffing body enclosed by a higher dense enclosed body, and a higher dense stuffing body enclosed by a lower dense enclosed body.

I I * * S S * S S * S * * * b *55 S description of each part of said auxiliary seat pad is as follows: As shown in FIG. 4 and 5, a support plate 10 is a rigid annular plate as a base to stand the weight of an invalid user, and sets a pair of screw hole 341 and limit hole 342 for joining with the guide bases 41.

As shown in FIG. 4, a stuffing body 20 is modeled in a annular layer with the thick light material and disposed on a support plate 10, with which a determined thickness raises up the surface of sitting part for an invalid to sit and bend his/her knee with less strength.

As shown in FIGS. I to 5, an enclosed body 30 is a foamed elastic annular layer to enclose a support plate 10 and a stuffing body 20 with a ventilated texture 31 on the surface, with which the gooseflesh-like texture offers the dry and skid proof contact for an invalid, and prefers using a waterproof material which is convenient for washing and cleaning. With certain thickness the enclosed body 30 soften the contact and last the usability. On the bottom inner edge of the enclosed body 30 is formed with a peripheral flange 32 for inserting to a toilet bowl. Therefore, the inner periphery 110 of the enclosed body 30 can connect with the inner bowl of a toilet. The density of a stuffing body 20 is relatively opposite to an enclosed body 30, for example, a lower dense stuffing body 20 is enclosed by a higher dense enclosed body 30, and a higher dense stuffing body 20 is enclose by a lower dense enc'osed body 30. Therefore, the auxiliary seat pad 100 can offer the softness and maintain a form as an invalid to sit on it.
