Description

[0001]
[Industrial application fields]
The present invention relates to a screw cap for hiding a screw head.
[0002]
[Prior art and problems]
Conventionally, when attaching an instrument such as a handrail in a unit bath, for example, as shown in the perspective view of FIG. 4 and the sectional view of FIG. 5, the instrument 51 attached to the wall panel 54 has a screw hole 52, A circular recess 53 is formed on the front side of the screw 55. The screw 55 is passed through the screw hole 52, the screw 55 is screwed into the wall panel 54, and the instrument 51 is fixed to the wall panel 54. In order to conceal, a screw cap 56 formed of a resin or the like in a circular shape is fitted into the circular recess 53 from the front side.
However, depending on the shape of the instrument 51, there may be a mold shape in which the circular recess 53 is difficult to be formed, and there is a problem that the circular screw cap 56 cannot be used or a scene that cannot be fixed securely occurs. It was.
[0003]
[Means for Solving the Problems]
The present invention has been devised in view of the above-mentioned conventional problems, and aims to provide a screw cap that can be securely attached to a tool and can hide the head of the screw. A screw cap that is attached to cover the head of the screw after being screwed to a wall surface or the like, and the screw cap is configured to be attached to the device in a flush manner . A hole for stopping the screw cap is formed in the vicinity of the screw hole through which the screw is passed. The screw hole and the hole for stopping the screw cap are formed in a communicating hole shape, and inserted and locked in the hole. The hook is provided on the screw cap.

【Example】
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an exploded perspective view of an instrument, a screw, and a screw cap, FIG. 2 is a sectional view of the instrument side, and FIG. 3 is a sectional configuration diagram of the screw cap attached.
[0005]
In the figure, the instrument main body 1 is a counter installed in, for example, a unit bath, and the rising wall portion of the instrument main body 1 is formed with a square front concave portion 2a and an upper surface concave portion 2b on the upper surface side. The front recess 2a is formed with a screw hole 3 for passing a screw penetrating to the back side, and a cap fixing hole 4 is formed in the lower part of the screw hole 3 so as to penetrate the back side. and which, screw holes 3 and the cap retaining hole 4 is in communication with the longitudinal bore 5 is formed in a hole shape.
[0006]
Further, an inner circumferential step 6 is formed one step higher on the outside of the front recess 2a and the upper recess 2b, and a back groove 7 is formed on the back side of the upper recess 2b by notching downward.
Further, as shown in FIG. 2, a hooking groove 8 is formed on the back side of the cap fastening hole 4 by notching upward. The hooking groove 8 may be formed in the lower part 8a on the back side of the cap stopper hole 4.
[0007]
The screw 9 can be screwed into the wall panel 14 as shown in FIG. 3 through the screw 9 in the screw hole 3, and the instrument body 1 can be fixed to the wall panel 14. In this state, the front recess 2a and the top recess The screw cap 10 is attached from the indoor side so as to cover 2b, and the head of the screw 9 is concealed so that a neat attachment state is obtained. The screw cap 10 is made of resin. The vertical piece 11 that covers the front surface of the front concave portion 2a and the upper surface piece 12 that covers the upper surface of the upper surface concave portion 2b are integrally formed in an L shape, and are engaged with the back groove portion 7 at the tip of the upper surface piece 12. A claw 12a is formed, and a hook 13 is integrally formed so as to protrude from the vertical piece 11 in parallel with the upper surface piece 12, and the hook 13 is formed into a shape that can be inserted into the cap fixing hole 4. 13 tip side Has a one hooking pawl 13a is engaged with the hooking groove portion 8 is formed.
[0008]
The right and left ends of the screw cap 10 having such a shape are brought into contact with the inner peripheral step portion 6, the claw 12 a is locked to the back groove portion 7, and the hook 13 is inserted into the cap fixing hole 4 to be hooked. The nail | claw 13a can be latched by the hooking groove part 8, and the screw cap 10 can be reliably attached to the instrument main body 1, and the head of the screw 9 will be in the state concealed completely in this state. The main body 1 is flush with the main body 1 and a clean installation state is obtained.
[0009]
In addition, since the instrument main body 1 shown in FIG. 2 cannot form a mold | die when it is going to form the conventional circular recessed part 53, and it is difficult to shape | mold a product, the front recessed part 2a of such a shape is used. Then, the upper surface recess 2b is formed, the screw cap 10 having the hook 13 is attached, and the head of the screw 9 is covered.
Therefore, it is possible to form the recesses 2a and 2b having such a shape for a tool having a shape in which the circular recess 53 cannot be formed, and to attach the screw cap 10 satisfactorily to obtain a clean installation state. It can be done.

【The invention's effect】
The present invention is a screw cap that is attached in order to hide the head of the screw after the device is screwed to a wall surface or the like, the screw cap being configured to be attachable to the device in a flush manner, On the device side, a hole for stopping a screw cap is formed in the vicinity of a screw hole through which the screw passes, and a hole shape for connecting the screw hole and a screw cap is formed in a hole shape . Since the hook that is inserted and locked to the screw cap is provided on the screw cap, the screw cap can be securely attached to a device having a shape that is difficult to form a circular recess as in the prior art, and the screw cap can A neat installation state can be obtained by hiding the head.
In addition, since the screw hole and the hole for stopping the screw cap are formed in a continuous hole shape, the screw hole and the hole for stopping the screw cap can be integrally formed, and the hole can be easily formed. .
