Benefits of technology

"The present invention is a pad with a deformable member that is received in an outer cover and a valve is used to control the air entering or escaping from the pad. The valve is designed to keep the pad in its deformed state when a user sits on it. The technical effect of this invention is to provide a comfortable and adjustable pad that can adapt to the user's needs while maintaining its original shape."

Problems solved by technology

However, each of the first and second foam pads has a fixed and unchangeable flexibility so that the deformation to the memory pad is different when different users of different weights sit on the memory pad.
Besides, the second pad foam easily traps the heat therein which makes the user feel uncomfortable after a longer period of use.

Embodiment Construction

[0017]Referring to FIGS. 1 to 3, the pad 10 of the present invention comprises an outer cover 20 which is made by Thermoplastic Polyurethane (TPU) which is durable and strong so that it can bear high load and does not cause permanent deformation. The outer cover 20 has an inner space 21 defined therein and an opening is defined in a side of the outer cover 20. A valve 22 is engaged with the opening and a cap 23 is removably mounted to the valve 22 which communicates with the inner space 21.

[0018]A deformable member 30 is received in the inner space 21 and includes a foam piece 31 with gaps 33 defined therein. Gel-type material 32 is spread to the foam piece 31 and movable within the gaps 33 in which air is received. The foam piece 31 can also be soaked in the gel-type material 32 to achieve the same purpose. The deformable member 30 does not bounce back after it is deformed.

[0019]The gel-type material 32 is a mixture of fluid gel and water at a certain proportion so that the water i...

Abstract

A pad includes an outer cover having an inner space and an opening is defined in a side of the outer cover so as to receive a valve therein. A deformable member is received in the inner space and includes a foam piece with gaps defined therein. The foam piece is spread or soaked with gel-type material which flows within the gaps. The air in the cover is expelled out from the valve when a user sits on the pad and the cap is then seals the valve. The air outside the pad cannot enter into the pad so that the shape of the deformed pad can be kept.

Description

BACKGROUND OF THE INVENTION[0001](1) Field of the Invention[0002]The present invention relates to a pad which is adjustable and remembers the deformation according to the user's weight.[0003](2) Description of the Prior Art[0004]A conventional pad is generally made by foam material which is deformable so that the pad is deformed when the user sits thereon, and the deformation of the pad makes the user feel comfortable. There are some memory pads in the market and includes a first foam pad with a second foam pad received in the foam pad. The first foam pad is made by a foam material with high flexibility and the second foam pad is made by a foam material with low flexibility. The second foam pad bounces very slow to achieve the “memory” feature. The first and second foam pads are received in a cover so as to keep the shape of the memory pad. However, each of the first and second foam pads has a fixed and unchangeable flexibility so that the deformation to the memory pad is different ...
