Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a suction cup attachment device for a case, and more particularly to a suction cup attachment device for a case that attaches a suction cup for adsorbing and fixing the case to a wall surface.

[Prior Art] Conventionally, it has been known to adsorb and fix a synthetic resin case to a wall surface of a bathroom or a bathtub with a suction cup. For example, Japanese Utility Model Laid-Open No. 185223/1983 discloses a case in which a bubble plate is housed and fixed. There is described that a suction plate is provided to the suction plate, and the suction plate is used to suck and fix the bubble plate to the inner wall surface of the bathtub.
In Japanese Utility Model Laid-Open No. 63-114640, a case is provided with a large number of holes to form a bubble generating portion, and a suction cup is provided on the case. The suction cup sucks and fixes the bubble generating portion to the inner wall surface of the bathtub. What is done is described.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, since the suction cup is usually screwed and fixed to the case or is fixed by adhesion, assembly of the suction cup is troublesome and the number of parts for fixing the suction cup increases. There was a problem that it hindered the replacement of the suction cup.

Therefore, an object of the present invention is to provide a suction cup attachment device for a case, in which the suction cup can be easily assembled and replaced and the number of parts for fixing the suction cup can be reduced.

[Means for Solving the Problems] According to the present invention, suction cups are provided on both sides of a substrate, the suction cups on one surface of the substrate are attracted to a spacer, and the suction cups on the other surface of the substrate are projected from a hole of a case. The substrate and the spacer are held between an internal component housed in the case and an inner surface of the case.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 to 3 show a first embodiment of the present invention, in which 1 is a case made of synthetic resin, which is composed of a lower case 2 and an upper case 3. Reference numeral 4 denotes a concave portion formed on the inner surface of the bottom of the lower case 2. A plurality of holes 5A are formed in the concave portion 4 by a retaining ring 5, and a peripheral wall portion 6 is formed on the outer periphery of the concave portion 4. Has been done. Reference numeral 7 is a substrate made of synthetic rubber, and a plurality of suction cups 8 and 8A are integrally provided on both surfaces of the substrate 7 so as to project therefrom. Reference numeral 9 denotes a flat plate spacer made of synthetic resin, and one surface of the spacer 9 attracts a plurality of suction cups 8 projecting from one surface of the substrate 7 and the peripheral wall portion 6 of the lower case 2
It is fitted and arranged inside. The board 7 is fitted and arranged in the recess 4 of the lower case 2 with a plurality of suction cups 8A protruding from the other surface of the board 7 protruding to the outer surface of the lower case 2 through the holes 5A. . Reference numeral 10 denotes an electrode plate which is an internal component electrically connected to a low frequency generator (not shown). It is temporarily fixed by being inserted into a plurality of temporary fixing pieces 11 formed integrally on the inner surface of the part.

An opening 12 is formed in the upper case 3, and a plurality of protrusions 13 for pressing the electrode plate 10 are provided on the inner surface. And a hook piece provided on the inner surface of the upper case 3.
The lock piece 17 provided on the slide knob 16 by inserting 14 into the groove 15 provided on the inner surface of the bottom portion of the lower case 2 and sliding the slide knob 16 provided on the side portion of the lower case 2. The upper case 3 is fixed to the lower case 2 by locking the hook piece 14. Reference numeral 18 is an engaging groove formed on the outer surface of the side portion of the lower case 2 and is an engaging protrusion 19 of the upper case 3.
Are to be engaged.

Thus, the suction cup 8 projecting from one surface of the substrate 7 is attracted to one surface of the spacer 9, and the suction cup 8A projecting from the other surface of the substrate 7 is passed through the hole 5A of the lower case 2 to the lower case 2. Of the electrode plate 10 on the other surface side of the spacer 9 so as to project into the outer surface side of the substrate 7, the spacer 7 is fitted in the concave portion 4 and the spacer 9 is fitted in the peripheral wall portion 6, respectively.
And affix this electrode plate 10 temporarily with a temporary stop piece 11,
In this state, the case 1 is assembled by fixing the upper case 3 to the lower case 2 by locking the hook piece 14 and the lock piece 17. Then, the suction cup 8 is used by adsorbing the case 1 on the wall surface of a bathtub or the like.

As described above, in the above-described embodiment, the suction cups 8 projecting on one surface of the substrate 7 are attracted to the spacers 9, and the suction cups 8A projecting on the other surface of the substrate 7 are inserted through the holes 5A of the lower case 2. The substrate 7 and the spacer 9 are arranged so as to project to the outer surface side and are arranged in the lower case 2, the electrode plate 10 is temporarily fixed, and then the upper case 3 is assembled to the lower case 2 so that the electrode plate 10 is pressed by the protrusions 13. Since the substrate 7 and the spacer 9 are held between the electrode plate 10 and the bottom portion of the lower case 2, the work such as the screw tightening or the adhesive bonding which is required for the suction cup assembly is not required. Assembling becomes easy, and the number of parts for fixing the suction cup can be reduced. Also, the suction cup can be easily replaced by removing the electrode plate 10. Further, the elasticity of the plurality of suction cups 8 provided on one surface of the substrate 7 causes the substrate 7 and the electrode plate 10 to be in pressure contact with each other with the spacer 9 interposed therebetween, so that the case 1 is sucked and fixed by the suction cups 8A. Also, the stability of the electrode plate 10 is ensured, and the device is highly reliable. The substrate 7 is prevented from being pulled out by the stopper 5.

FIG. 4 shows a second embodiment of the present invention. In this embodiment, a plurality of elastic claw pieces 20 projecting from the inner surface of the bottom of the lower case 2 are engaged with an internal component 21 to lower the internal component 21 and the lower component. Since the substrate 7 and the spacer 9 are held between the bottom of the case 2 and the case 1, the suction of the case 1 by the suction cups 8 and 8A and the stability of the internal component 21 are good as in the above-described embodiment.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. For example, the number of suction cups protruding from both surfaces of the substrate, the shape and size of the substrate and the spacers may be appropriately selected.
Further, the internal parts can be applied to various types such as an electrode plate and a bubble plate.
The fixing means for the upper and lower cases may be selected appropriately.

[Advantages of the Invention] The present invention provides suction cups on both sides of a substrate, sucks the suction cups on one surface of the substrate to a spacer, and projects the suction cups on the other surface of the substrate from a hole of a case to form the substrate and the spacer. By holding between the internal parts housed in the case and the inner surface of the case, it is easy to assemble and replace the suction cup and reduce the number of suction cup fixing parts. A device can be provided.
