Description

[Detailed description of the invention] This invention relates to a cancher for the door of a sink or the like.

It has been common practice in the past to lock double doors in the closed position using a catcher consisting of a female member and a male member.

The cancher has a male member fixed to the inside of the door, a female member fixed to the lower surface of the top plate of the main body, and the door is held in the fully closed position by engaging the male member with the female member. There is.

Catchers have traditionally existed in which the male and female members are molded from synthetic resin, but with this type of catcher,
Since both the male and female members are fixed, if there is an error in the mounting position, it will not be possible to properly engage the male member with the female member.

Therefore, there is a drawback that accurate installation is required and the installation process is time-consuming.

In addition, even if the initial installation is accurate, if the door tilts or shifts downward due to frequent opening and closing, it will not be possible to properly engage the male and female members, so It is necessary to provide a support plate separate from the cancher to prevent displacement.

This invention solves the above-mentioned drawbacks, allows the male and female members to be reliably engaged even if there is a positional error in their relative mounting, and prevents the door from tilting or shifting. This provides a cancher that allows you to do this.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, the cancher of this invention consists of a case 1 attached to the lower surface of the top plate of the main body, a female member 20 swingably supported by the case 1, and a male member 30 fixed to the inside of the door. I warn you.

The case 1 includes a bottom plate 2, and the tip of the bottom plate 2 forms an inclined surface 3 that slopes in a photon direction.

Further, a peripheral wall 4 whose front side is open stands up on the outer periphery of the bottom plate 2, and a protruding shaft 5 standing up from the bottom plate 2 is provided inside the peripheral wall 4.

A flange 6 is provided on the upper edge of the side wall facing the peripheral wall 40, and a notch 1 is formed inside the upper edge of the side wall, and the protrusions 9 on both sides of the upper cover 80 are fitted into the notch 1. It has become.

Note that 10 is a long hole formed in the flange 6.

The female engraving member 20 has a cylindrical support part 21, a pair of elastic arms 22 are formed on the outer periphery of the support part 21, and a bulge having an arcuate outer surface is formed at the tip of each arm 22. A portion 23 is formed.

The female member 20 is rotatably supported by inserting the support portion 21 into the protruding shaft 5 of the case 1, and is rotatably supported by the outer surface of the arm 22 and the peripheral wall 4.
The rotation angle is limited by contact with the front edge of the cylindrical clamping body 23, and the pair of cylindrical clamping bodies 23 are maintained facing forward.

The male member 30 also includes a mounting plate 31 and a mounting plate 3.
1, and an engagement protrusion 33 is formed at the tip of the protrusion 32.

The width dimension of this retaining protrusion 330 is larger than the dimension between the clamping bodies 23.

Additionally, chamfers 34 are provided on the top and bottom of the tip.

Note that, as shown in the figure, the engagement protrusion 33 is preferably tapered at its tip so that it can easily fit between the pair of clamping bodies 23, and also has inclined surfaces 35 on both sides of the back of the engagement protrusion 33.
to ensure reliable engagement with the clamping body 23.

Note that 36 is a mounting hole formed in the mounting plate 31.

This device consists of the above-mentioned structure, and the case 1 with the top cover 8 attached is attached to the lower surface of the top plate of the main body A as shown in FIG. In this state, the male member 30 is attached at a position corresponding to the female member 20.

After installing the cancher as described above, when the door B is rotated to the closed position, the engaging protrusion 33 of the male member 30 engages the pair of clamping bodies of the female member 20 whose direction is regulated by the front edge of the peripheral wall 4. 23, the rear inclined surface 35 of the engaging protrusion 33 engages with a part of the outer peripheral surface of each clamping body 23, and the door B is locked in the fully closed position.

Now, even if there is an error in the relative mounting positions of the female member 20 and the male member 30 in the horizontal direction, if the error is within the range in which the female member 20 can swing, the door B will be in the fully closed position. Shortly before this occurs, the engaging protrusion 33 of the male member 30 collides with one of the clamping bodies 23 of the female member 20 and rotates this female member 20, so that the locking protrusion 33 corresponds between the pair of clamping bodies 23. However, the male member 30 and the female member 20 can be engaged with each other.

Now, if the end on the opening/closing side is lowered and the upper line becomes as shown in Figure 4 when this door B is in the open state, then when this slanted door B is closed, before it reaches the closed position. , the chamfer 34 on the lower side of the retaining protrusion 33 is the tip inclined surface 3 of the bottom plate 2.
The inclination of the door B is thereby corrected, and the male member 30 can be reliably engaged with the female member 20.

In the embodiment, the front edge of the peripheral wall 4 is used as a stopper, and the swing angle of the female member 20 is limited by the contact between this stopper and the outer surface of the arm 22. However, a protrusion may be provided on the upper surface of the bottom plate. By doing so, it is also possible to limit the swing angle of the female member.

As described above, according to this invention, even if there is a gap in the relative mounting position of the female member and the male member, since the female member is swingably supported, the male member cannot be connected to the female member. Therefore, installation is easy.

In addition, a sloped surface is provided at the tip of the bottom plate, and the engaging protrusion of the male member is chamfered at the top and bottom of the tip, making it possible to reliably engage the female member and male member even with a tilted door. Furthermore, since the protrusion of the male member is supported by the bottom plate of the case when the door is closed, the door can be prevented from tilting or shifting, and a support plate provided separately from the cancher can be omitted.
