Description

[Detailed explanation of the invention] (1) Purpose of the invention (industrial application field) This invention relates to a catch plate that is engaged by a sickle that protrudes from a locking device arranged on the end face of a sliding door when the door is locked. It is.

(Prior art and issues to be solved) A frame housing a sliding door is fixed to the inside of a pillar or stile on the side of a house, and a sickle protruding from a sickle lock attached to the end face of the sliding door is fixed. BACKGROUND ART Sashes configured to be locked by engaging with a catch plate disposed on the frame side have been widely used.

In the above-mentioned sash, grooves are formed on the inner surface of the frame on which the door slides (horizontally) and to ensure a tight seal when the door is closed (vertically). However, there are some types with one groove and others with two grooves, and in order to adapt to these types of locks, even if the lock is the same, the catch plate has two grooves to suit each.
There was a problem in that it was necessary to prepare different types of products, and that handling and management during production and processing at the site were troublesome.

This will be briefly explained with reference to the figures shown below in Figure 4A. Figure 4A is the locking device attached to the door side, Figure 4B
The figure is a perspective view showing a catch plate attached to the grooved frame side, and a knob 3 that is manually rotated to lock and unlock is provided on the locking device side. Kamakin 5
(indicated by a chain line) rotates to emerge and retract from the locking device. The reference numeral 1 in Figure 4B is a catch plate that is fixed to the door frame side, and this figure is suitable for one with a single groove on the frame side, and the main parts are shown in a plan sectional view in Figure 5. , in the case of a single groove, one plane part of the catch plate 1 is placed along the bottom of the groove and fixed with a screw 8, and the openings 1a and 1b of the other plane part face the sickle 5 of the locking device. The sickle 5, which appears and retracts as the knob 3 is rotated, is inserted into and removed from the opening to lock and unlock the opening.

If the door frame has two grooves and there are two doors, it will be necessary to lock and unlock the door located in the groove on the side far away from the room, so in this case, the door frame as shown in Figure 6 will be used. A catch plate 11 having a substantially U-shaped cross section is used, and as shown in FIG. The parts 11a and 11b are configured to face the sickle 5 of the locking device so as to be locked and unlocked.

Since the structure of the catch plate must be changed depending on the difference in the structure of the door, various efforts are required as described above.

The present invention was developed in order to deal with this situation, and by making it possible to use a single catch plate regardless of the structure of the frame body, it is possible to avoid the above problems and improve production and site The object of the present invention is to provide a catch plate that can be easily handled.

(2) Structure of the invention (technical means for solving the problem, and its effects) In order to achieve the above purpose, the invention is based on a method in which both ends of the catch plate of a sliding door have different lengths in opposite directions. When the plate body is bent to form a substantially Z-shape when viewed from the end face, the bent portions at both ends of the plate body are attached to a single-strip groove for storing a sliding door, and It is characterized by having openings for engaging and releasing the sickles at positions corresponding to the sickles of the sickle locks provided on the respective sliding doors when installed upside down in the groove. .

By configuring it in this way, it is possible to use a single catch plate to fit all door frames regardless of differences in their configurations and dimensions, which simplifies production, on-site management, and handling, and reduces costs. It is also advantageous.

(Explanation of an embodiment) Fig. 1 is a perspective view showing the configuration of a catch plate according to the present invention, in which one flat plate is bent at a right angle (almost in a Z-shape) so that both sides are in opposite directions from about the middle. )
Openings 6a, 6a and 6b, 6b into which the sickle engages are formed in the flat parts a, b at both ends, and holes into which screws to be attached to the door frame are inserted are formed in each flat part a, b. It has been formed.

Because of this structure, whether there is one or two grooves in which to attach the catch plate on the frame side, and regardless of which groove the door with the lock is attached to, there is only one groove. In the case of a groove, by attaching the side b in Figure 1 to the frame, and in the case of a two-strip groove, attaching the side a to the frame, attach the seat plate side to the position of the sickle on the lock side. The seat plate can be arranged and fixed so that there is an opening.

Fig. 2 is a plan sectional view of the main part showing the case where the above-mentioned catch plate 6 is applied to a door frame having one groove.
The figure shows a case where the grooves on the outdoor side of a door frame with two grooves are arranged so as to be suitable for locking and unlocking the door.

By the way, there is usually one groove 9 in the width of the groove part of the door frame.
There are cases where there is a, and cases where there are two 9b and 9b (see Figures 2 and 3), and there are differences in the groove width between the two, and also depending on the position of the groove that fixes the catch plate. Since the distance between the knob 3 and the positions of the openings 6a and 6b where the sickle engages will be different, the width of the flat part _a and the width of the flat part _l2 should be adjusted to match this.
The groove widths are made different to match the distances, and the positions of the openings 6a and 6b are arranged so that the distances from the center of the catch plate are appropriately different.

(3) Effects of the invention As explained above, according to the invention, one or more Z-shaped bent catch plate is provided with one or two grooves by changing the direction at any time. Since it can be adapted to the frame body, there is no need to take special care to align the combination of the lock device and the seat plate during production and on-site, which has a remarkable effect on improving efficiency and reducing costs.
