Description

[Detailed Description of the Invention] The present invention relates to a bathroom drainboard which is novel and has great industrial applicability.

Traditionally, bathroom grates were made of synthetic resin.
Generally, a top plate and foot material that have been molded separately are pasted together with adhesive, and the bottom surface of the foot material is treated with a non-slip finish. The process of gluing the top board and foot material using wood is extremely complicated and creates a cost increase factor, and the manufacturing process not only limits the size of the product, but also reduces the bonding process of the top board and foot material due to the use of adhesive. It has many drawbacks, such as the fact that it tends to cause adhesive distortion or deformation of the overall shape, and that it is impossible to replace only the top plate, which is prone to wear.

The purpose of the present invention is to completely eliminate the drawbacks of the conventional products by using a new structure.

Next, the configuration of the present invention will be specifically explained with reference to the drawings showing one embodiment.

1 is a hard or soft synthetic resin substrate, 2 is a
The horizontal connecting holes 3 and 4 formed at each corner of the synthetic resin substrate 1 are connected to mutually corresponding engagement protrusions provided on the side peripheral wall of the synthetic resin substrate 1, respectively. and an engaging recess, which is shown in FIGS. 1 and 2.
The figure shows a plurality of synthetic resin substrates 1, 1 in which one engagement protrusion 3, 3 each having an L-shaped cross section is bored on both sides of the peripheral wall in the longitudinal direction of a rectangular synthetic resin substrate 1. This figure shows an embodiment in which an engaging recess 4 having an inverted L-shaped cross section is omitted at a position corresponding to the engaging protrusions 3, 3 when they are arranged adjacent to each other in parallel.

Reference numerals 5...5 are draining posts that are protruded in large numbers on the back surface of the synthetic resin substrate 1, and due to the presence of the draining posts 5...5, the synthetic resin substrate 1
A gap 7 is provided between the mounting surface 6 and the mounting surface 6.

The synthetic resin substrate 1, as shown in FIG. 1, can be conveniently transported and stored if it is formed from two unit substrates 1' and 1' that can be freely engaged and detached from each other.

Reference numeral 8 denotes a foamed plastic plate which is superimposed on the synthetic resin substrate 1, and has connecting holes 9 formed at corner positions corresponding to the connecting horizontally elongated holes 2 of the synthetic resin substrate 1. shall be. Incidentally, the connecting hole 9
Due to the flexibility of the foamed plastic board 8, the shape may be circular, as shown in FIG. Such a shape is preferable from the viewpoint of allowing insertion and maintaining strength.

Reference numeral 10 denotes a connector for vertically fastening the foamed plastic plate 8 and the synthetic resin substrate 1, and includes a shaft portion 103 that passes through a drain hole 101 in the central axis direction and connects to the flat plate-like top portion 102. The distal end thereof is formed into an oblong locking portion 104 that can be inserted into the oblong connecting hole 2 of the synthetic resin substrate 1 .

As shown in Fig. 1, in the drainboard of the present invention,
The connectors 10, 10, 10, 10 are connected through the connecting holes 9, 9, 9, 9 of the foamed plastic board 8 and the horizontal connecting holes 2, 2, 2, 2 of the synthetic resin substrate 1,
The connecting tools 10, 10, 10 are inserted into the foamed plastic board 8 and the synthetic resin substrate 1 from above and below.
10 is rotated to rotate the locking part 104 in a direction intersecting with the horizontal connecting hole 2 of the synthetic resin substrate 1, thereby locking the locking part 104 to the back surface of the synthetic resin substrate 1. Therefore, the unit slatted body 11 in which the foamed plastic board 8 and the synthetic resin substrate 1 are vertically superposed can be formed extremely easily and reliably. In this case, a plurality of unit slat bodies 11 are arranged adjacently so as to have an arbitrary shape, and are interconnected by the engaging protrusion 3 and the engaging recess 4 in the manner shown in FIG. Needless to say, it is possible to easily and reliably obtain a desired bathroom drainboard of any shape.

As shown in Fig. 4, in the drainboard of the present invention,
When a pressing force is applied to the connector 10 in the direction of the arrow, in other words, when the connector 10 is used in the bathroom, the connector 10
When the part is pressed with the ankle or buttocks, the connecting device 1
0 is pressed down into the downward cavity 7 as the elastic foamed plastic plate 8 is compressed, and thus,
The locking portion 104 forming the tip of the connector 10 is connected to the mounting surface 6.
Therefore, despite the presence of the connector 10, there is almost no discomfort felt on the ankle etc. when the connector 10 is pressed. It is.

In addition, when the pressing force on the connector 10 is released, the restoring elasticity of the foamed plastic plate 8 causes the connector 10 to immediately return to the position indicated by the two-dot chain line in FIG.

The drainboard of the present invention has the following effects due to the above structure and operation.

(a) Since the structure is such that a foamed plastic board 8 and a synthetic resin substrate 1 are vertically overlapped and connected using a connecting tool 10 to form a unit slatted body 11, it is not possible to form the upper board and the foot material by bonding the upper and lower parts together. Not only can bathroom grates completely eliminate the drawbacks caused by the existence of an adhesive process, such as increased cost, limited product size, distortion of the adhesive between upper and lower layers, and deformation of the overall shape over time, but also The foamed plastic plate 8, which is the upper flexible layer, which is subject to severe wear and tear, can be replaced at will, and the benefits in these respects are great.

(b) Any shape can be formed by connecting the unit slatted body 11, and since the unit slatted body 11 itself is separated into the foamed plastic board 8 and the synthetic resin substrate 1, a large-shaped bathroom can be formed. The drainboard can be easily and freely formed, and is still convenient to transport.

(c) Although the connecting device 10 is used to vertically connect the foamed plastic board 8 and the synthetic resin substrate 1 in order to obtain the above advantages, due to its structure, even when the connecting device 10 is pressed, It hardly gives a sense of discomfort to the sense of touch, and has a special effect in that respect.

(d) It can be manufactured relatively cheaply due to its configuration.

(e) It has a great water removal effect.
