Description

[Detailed description of the invention] (Field of industrial application) This invention is attached near the opening/closing surface of the main body of furniture that opens and closes with a door, and is attached mainly to the back side of the free end of the door with a protruding neck and a triangular or diamond shape. This invention relates to a roller type catch that moors a door in a closed state by elastically engaging the head of a male member (strike) with a pair of rollers.

(Prior art) When closing a door with such a roller type catch, simply push the door lightly, the head of the male member passes between two opposing rollers, and the head of the male member is caught and moored in the closed state. Japanese Utility Model Publication No. 46-21411 discloses a device in which a male member cannot be passed between two opposing rollers in the opposite direction unless the door is opened and closed with a large force. .

(Problem to be solved by the invention) In the above conventional example, there is a mounting part to the furniture body, two arms extending from this mounting part, and the tips of both arms movably support each end of the shaft of the opposing roll. The paired bearings are formed by intricately bending a single thin metal plate, which is very time-consuming and requires a lot of effort.
It is very time-consuming to assemble the metal plate spring because it has to be bent into a U-shape and then both ends of the U have to be folded back in a complicated manner.

(Means for solving the problem) Therefore, the roller type catch for doors of furniture, etc. of the present invention includes a mounting board, two elastic arms projecting in a V shape from the mounting board, and each of the arms. has a slit that protrudes from the tip of the arm in a direction perpendicular to the direction in which the arm extends, faces each other, and extends in a direction perpendicular to the direction in which the arm extends; A body is integrally molded of plastic and has a pair of bearing pieces movably supported along the slit, and each of the two arms projecting in the V shape is provided with the free end facing the tip of the arm. It is characterized in that a tongue-shaped elastic piece that comes into contact with a roller whose shaft is supported by a slit in each pair of bearing pieces is formed by cutting into a U-shape.

(Embodiment) In the illustrated embodiment, 1 is a main body made of plastic, a mounting board 2, two elastic arms 3 projecting in a V shape from one side of the mounting board,
3, and bearing pieces 4, 4 for a pair of upper and lower bearing pieces 4, which are formed in a U-shape facing each other and protrude from the tip of each arm in a direction perpendicular to the direction in which the arms extend, Each pair has slits 5, 5 extending in a direction perpendicular to the direction in which the arms 3 extend.
is provided. Reference numeral 6 denotes a roller held between each pair of the bearing pieces 4, 4, and from the center of its upper and lower surfaces protrudes a shaft 6' housed in the slits 5, 5 and movable along the slits. Preferably, this roller 6 is also molded integrally with the shaft 6' from plastic. The roller 6 elastically spreads the space between each pair of bearing pieces 4, 4, and accommodates the shafts 6', 6' protruding from the upper and lower surfaces into the slits 5, 5 of the upper and lower bearing pieces 4, 4.

Each of the arms 3 has a tongue-shaped elastic piece 7 formed with a U-shaped notch 7' with its free end facing the tip of the arm, and as described above, each roller 6 is connected to the bearing piece 4,
4, each elastic piece 7 contacts each roller 6 with opposing surfaces.

A male member 11 having a triangular or diamond-shaped head 9 and neck 10 is attached to the inner surface of the free end of the furniture door 8 as shown in FIG. The main body 1 is located at a portion facing the member 11.
Attach with mounting board 2.

As a result, when the door 8 is pushed to close as shown in Fig. 2, the head 9 of the male member inserts itself between the opposing rollers 6, 6 as shown in Fig. 3, and each roller 6 is pushed away. The elastic pieces 7 of each arm are bent and moved outward along the slits 5, 5 of each pair of bearing pieces 4, 4. When the head 9 has finished passing, the restoring force of the elastic pieces 7 causes the slits 5, 5 to move outward. 5 and move inward along neck 1 of the male member.
0 and moor the door 8 in the closed state (Fig. 4).

When the closed door 8 is pulled forward to open it, the rollers 6, 6 are caught by the jaws 9' of the head, and due to the direction of the force, cannot move through the pair of slits 5, 5 of each bearing piece, and the head is opened by pushing the arms 3, 3 outward through each roller as shown in FIG.
You have to pass through it in reverse.

Therefore, when closing the door 8, it can be moored by simply pushing the door lightly, but when opening it, it is necessary to pull the door with a certain amount of force, and it is possible to reliably prevent the closed door from opening unexpectedly.

(Effect of the invention) The main body, which has a mounting board, two arms protruding in a V shape from the mounting board, and a pair of bearing pieces at the tip of each arm, is integrally molded of plastic, contacts each roller, and has a roller that is inserted into the body. The biasing action to move the arm in the opposite direction is performed by an elastic piece formed by a U-shaped notch in each arm, so there is no need to bend the thin metal plate in a complicated manner or use a separate spring.

Therefore, manufacturing and assembly are easy and productivity is significantly improved.

[Brief explanation of the drawing]

The drawings show one embodiment of the present invention; Fig. 1 is a perspective view showing the state in use, Fig. 2 is a plan view of the state in the middle of closing the door, and Fig. 3 is a plan view of the state immediately before the door is closed. Figure 4 is a plan view of the door when it is closed, Figure 5 is a plan view of the door being opened, Figure 6 is a top view with one half cut away, and Figure 7 is the same as Figure 6. 8 is a side view of FIG. 6, FIG. 9 is a front view of FIG. 6, and FIG. 10 is a rear view of FIG. 6. In the figures, 1 is the main body, 2 is the mounting board, 3 , 3 is the arm,
4, 4 are a pair of bearing pieces, 5 is a slit, 6 is a roller, 6' is its shaft, 7 is an elastic piece, and 7' is a U-shaped notch.

Claims (1)
