A cushion block for using in a build-up surface formed by strips is disclosed to have two male coupling devices at one end, two female coupling devices at an opposite end corresponding to the male coupling devices, a retaining device protruded from one side thereof and adapted to secure the strip to the corresponding side of the cushion block, and a deformable body connected between the male coupling devices and the female coupling device. The male and female coupling devices are so made such that multiple cushion blocks are connectable in a line in a linking direction by engaging the male coupling devices of one cushion block into the female coupling devices of another. The deformable body is deformable in the linking direction to compensate expansion of the strips due to absorption of moisture.
A cushion block for using in a build-up surface formed by strips, said cushion block comprising at least one first coupling device at one end thereof, at least one second coupling device at an opposite end thereof corresponding to said at least one first coupling device, said at least one first coupling device and said at least one second coupling device being made such that multiple cushion blocks are connectable in a line in a linking direction by engaging the at least one first coupling device of one cushion block into the at least one second coupling device of another cushion block, a retaining device protruded from one side thereof and adapted to secure the strip to the corresponding side of the cushion block, and a deformable body connected between said at least one first coupling device and said at least one second coupling device and deformable in said linking direction.

1. Field of the Invention
The present invention relates generally to construction materials for upholstery and, more specifically, to a kind of cushion blocks for use in setting a build-up surface, such as wooden flooring, wooden wall or wooden ceiling.
2. Description of the Related Art
FIG. 1 is a perspective view of a cushion block according to a preferred embodiment of the present invention.
FIG. 2 is a top plain view of the cushion block according to the preferred embodiment of the present invention.
FIG. 3 is a sectional view taken along line 3-3 of FIG. 2.
Referring to FIG. 1, a cushion block 10 is a flat rectangular block molded from synthetic resin (for example, polyacrylic resin or polyethylene resin) in integrity, having a base 20 disposed at one end, two male coupling devices 40 arranged in parallel at the other end, a deformable body 30 connected between the base 20 and the male coupling devices 40, two female coupling devices 50 arranged in parallel in an outer side of the base 20 remote from the deformable body 30, a retaining device 60 located on the top side of the base 20 and spaced between the deformable body 30 and the female coupling devices 50, and two pairs of springy supporting devices 70 located on the top side of the base 20 and symmetrically disposed at two sides of the retaining device 60.
The retaining device 60 projects upwards from the top side of the base 20. Except the retaining device 60, the top sides of the other parts of the cushion block 10 are maintained in flush (the springy supporting devices 70 are normally disposed in a sloping position partially protruding over the top side of the base 20, however they become in flush with the top side of the base 20 when forced downwards).
According to the present preferred embodiment, the thickness of the cushion block 10 is about 1 cm (the height of the protruding retaining device 60 excluded). The length of the cushion block 10 (i.e., the length front the outer end of the male coupling device 40 to the outer end of the female coupling devices 50) is about 10 cm. The width of the cushion block 10 is about 7 cm. For easy understanding of the present invention, the direction passing through the male coupling devices 40 and the female coupling devices 50 is defined as “linking direction”.
