Description

[Detailed Description of the Invention] The present invention relates to a structure for attaching a lock to a sliding door made of glass plates or the like. In other words, there are two types of sliding doors made of glass plates, etc.: those that are constructed by incorporating a glass plate into a metal or wooden frame, and those that are constructed from the glass plate itself without using a frame. belongs to.

Traditionally, sliding doors made of glass plates themselves have been used in relatively simple places such as casework and furniture due to the weight of the glass plate, and the reality is that locks have not been actively installed. be. When attaching the lock, slide the glass plate to the closed position and drill a hole in the overlapping part with a diameter larger than the lock body, aligning each hole, and insert an elastic member into the hole in the front glass plate. The positioning member of the lock body was fitted onto the top, and the lock body and fixing plate were screwed to the positioning member. Similarly, elastic members were interposed in the holes in the rear glass plate and in the vicinity of the holes, and auxiliary hardware was positioned and screwed. For this reason, not only did the installation work take time and effort, but all the work had to be done at the assembly site, leading to high costs. Moreover, the lock body is exposed from the front glass plate surface, which is not only dangerous but also undesirable in terms of appearance.

In addition, in general, in sliding doors, the gap between the glass plates is different due to the difference in the rail spacing. In order to easily obtain a locking effect that overcomes the difference in overlap spacing, a conventional screw tightening structure is used, but since the threaded rod is exposed from the surface, it is difficult to lock the locking effect from the surface, such as on a case or furniture. It was not possible to implement it in the places where it could be obtained.

The present invention was developed in view of the above-mentioned circumstances, and simply requires cutting the sliding corners of the glass plate and attaching a reinforcing plate with holding holes at the cut locations, making it possible to install the glass plate in the same manner as in the past. It is possible to omit any work, and moreover, the lock can be inserted and removed through the holding hole, and a strong locking effect can be obtained. Hereinafter, the present invention will be explained based on an illustrative embodiment.

A is a sliding door, b is a lock that is removably attached to the sliding door a, c is a door wheel, and d is a key.

Reference numeral 1 indicates a front glass plate constituting a sliding door a, 2 indicates a rear glass plate, 1a and 2a indicate cutting gaps obtained by cutting the lower end corner of the sliding sliding door a into a substantially rectangular shape symmetrically;
1b and 2b are contact surface areas on both sides of the glass plate near the respective cutting intervals 1a and 2a. 3 is a first reinforcing plate attached to the front glass plate 1, 4 is a second reinforcing plate attached to the rear glass plate 2, and both reinforcing plates 3 and 4 are made of metal such as aluminum or durable synthetic material. Each bottom plate part 3a, 4a is made of resin and has a glass plate wall thickness interval, and a pair of opposing pieces 3b, 3c, 3b, each raised from the direction of the bottom plate part wall thickness gap,
It has a U-shape consisting of 4e. Each opposing piece 3
b, 3c and 4b, 4c each have a substantially square shape,
Both sides are mounted by sandwiching the glass plate adhesion surface areas 1b and 2b, respectively, and the respective cutting gaps 1a and 2a are connected to the respective bottom plate parts 3a and 4a and the opposing pieces 3b, 3c, 4b and 4.
partitioned by c, and located in the cutting gaps 1a and 2a. A bayonet lock (b) or door wheel (c) can be attached to the triangular area.

Reference numeral 5 denotes a holding hole located in the upper part of the cutting gap 1a and drilled in the facing piece 3b of the first reinforcing plate 3, and has a circular groove on the lower side to allow the passage of the insert lock b described below. 5a. Reference numeral 6 designates a holding hole similarly drilled in the opposing piece 3c, which can be bored at the same position and with the same diameter as the holding hole 5 without providing the groove 5a. Reference numeral 7 denotes a holding hole drilled in the facing piece 4b of the second reinforcing plate 4, which is bored at the same position and with the same diameter as the holding hole 6. Each holding hole 5, 6, 7 communicates with the glass plates 1, 2 at the same position at the sliding closing position, and there is a cutting gap of 1 between the holding holes 5, 6.
a, a sliding gap 8 is interposed between the holding holes 6 and 7, and a cutting gap 2a is interposed between the holding hole 7 and the opposing piece 4c. 1
The structure is such that insert lock b is embedded in a, 8, and 2a.

9 and 10 are the bearing holes for the door wheels c and c which are drilled in the lower opposing pieces 3b, 3c, 4b and 4c of the holding holes 5, 6 and 7, respectively; 11 and 12 are the bearing holes that are drilled in the bottom plate parts 3a and 4a respectively and are the bearing holes for the door roller c. , c This is a hole for the door roller that allows rolling.
The door roller c can be installed in the bearing hole 9, 9 or 1 by simply opening the free end of the opposing piece 3b, 3c or 4b, 4c and pushing it in.
An axle can be attached to 0 and 10, and may be attached in advance.

Next, insert lock b is explained. The insert lock b is a pin cylinder lock having an outer shape of a cylindrical body 13 that matches the outer shape of the above-mentioned holding hole, and a window hole 14 is bored in the tip side of the cylindrical body 13. A locking protrusion 15 on the front side is protruded from the proximal end portion spaced apart from the window hole 14, and a locking claw 16 as a locking protrusion on the rear side from the window hole 14 can be freely raised to be engaged. The structure is such that the opposing pieces 3c and 4b of the sliding door a are sandwiched between the stopper claw 16 and the stopper protrusion 15. The locking pawl 16 is raised by a conversion mechanism consisting of a sliding tube 17 inserted into the cylindrical body 13, a rotating tube 18, a pin guide column 19, and a rotating body 20. A regulating rod 22 implanted in the cylindrical body 13 is inserted into a rotation regulating hole 21 drilled in the direction to regulate the sliding tube 17 in the front-rear direction, and a drive guide hole bored diagonally in the sliding tube 17 is inserted. 23, the guide rod 24 of the rotating tube 18 is engaged, and the sliding tube 17 is slid in the front-rear direction to cause the locking pawl 16 to rise from the window hole 14.

Next, installation will be explained.

Glass plate 1 whose lower end corner has been cut in advance,
2 to the closed position and cut the cutting gaps 1a, 2a.
Prepare by overlapping. In addition, first and second reinforcing plates 3 and 4 are prepared in which door wheels c and c are installed in bearing holes 9, 9, 10, and 10, respectively, in advance. Although not shown, it goes without saying that if the door roller is not attached, a reinforcing plate may be provided.

The first reinforcing plate 3 is sandwiched between the front glass plate 1, and the opposing pieces 3b, 3c are attached to the contact surface areas 1b, 1b.
Glue and fix a part of it.

Next, the second reinforcing plate 4 is sandwiched between the rear glass plate 2, the holding holes 7 are aligned with the holding holes 5 and 6 of the first reinforcing plate 3, and then the holding holes 5 and 6 of the first reinforcing plate 3 are aligned and then fixed by adhesive to complete the work.

When locking the sliding door a, open the glass door 1,
2 to the closed position and overlap each other, each holding hole 5,
6 and 7 are connected. In this state, if the insert lock b with the key d integrally fitted is inserted into each holding hole 5, 6, 7, the locking protrusion 15 passes through the groove 5a of the holding hole 5 and hits the opposing piece 3c. the lock position. Next, when the key d is rotated, the locking claw 16 engages the opposing piece 4b.
A facing piece 3c of the glass plates 1 and 2 stands up from the back side toward the front and is located between the locking claw 16 and the locking protrusion 15.
4b is inserted and locked. When unlocking, when the key d is fitted and rotated, the locking claw retracts into the window hole 14 from the back side of the opposing piece 4b, so the key d
Pull out the insert lock b from the holding holes 5, 6, and 7 to unlock it.

According to this embodiment, the cutting gaps 1a, 2
The recessed lock b can be operated using the sliding gap part 8 between the sliding door a and the sliding door, and the lock is not exposed from the front side of the sliding door, and the lock does not protrude to the rear side due to the restriction of the opposing piece 4c. Therefore, a reliable locking effect can be expected by completely embedding the insert lock b in the gap, and this can be suitably implemented when attaching the insert lock to a case or the like. In addition, since the opposing pieces 3c and 4b are sandwiched with a sliding gap 8 interposed between them, not only can the locking stroke be shortened, but also the locking can be performed without backlash by pressing both glass plates, and the rail spacing can be adjusted to some extent. Even if there is a difference, it can be installed and locked without requiring any design changes.
Furthermore, since the cutting gaps 1a and 2a are formed in a substantially triangular shape, it is possible to install the lock b in the upper part and the large door wheel c in the lower part in the minimum space. By simply cutting the parts and fixing the reinforcing plate to which the door roller is attached, it can be easily applied to large sliding doors, and the strength of the door roller mounting part can be guaranteed.

This mounting structure can also be applied to other insert locks b as shown in FIG. In this case, the holding holes 25 are also drilled in the opposing piece 4c, and each holding hole 5, 6, 7, 25
The holding holes 5, 6, 7, and 25 are provided with grooves 5a, 6a, 7a, and 25a, respectively.
Form a and 6a into large sizes. The insert lock b' has a cylindrical body, and is spaced apart from the lock bolt 26 as a rear locking protrusion that protrudes from the tip notch and rotates in the radial direction, and the lock bolt 26 as a rear locking protrusion. The lock bolt 26 and the locking protrusion 27 on the front side are arranged in the same position and inserted into each holding hole 5, 6, 7, 25, and the lock bolt 26 is inserted into the opposing piece. It is located on the back side of 4c and is in the locked position. The locking protrusion 27 fits into the grooves 5a, 6a of the holding holes 5, 6 and abuts against the surface of the facing piece 4b. When the key d is rotated in this state, the lock bolt 26 rotates from the groove 25a and locks by sandwiching the back surface of the opposing piece 4c. When unlocking, insert the lock bolt 26 into the groove 25.
Rotate it to a position and pull out the cylindrical body to unlock it. In this case, the retaining hole 25 cannot be drilled and the lock bolt 2
6 can also be implemented so as to rotate in the cutting gap 2a. Although the above description has been made regarding attachment to a glass plate, it can equally be applied to a synthetic resin plate.

Accordingly, the present invention achieves the following effects.

○B The lock can be installed by simply inserting and gluing the first reinforcing plate into the cut area of the front glass plate, then inserting the second reinforcing plate into the cut area of the rear glass plate, aligning the holes, and gluing. When locking and unlocking, all you have to do is insert and remove the lock into the holding hole, and all the troublesome work of installing the lock as in the conventional method can be omitted. In this case, even if the glass plate is cut appropriately in advance, a proper locking point can be formed by adjusting the mounting position of the reinforcing plate, and it is sufficient to simply glue the reinforcing plate on site.

○B By inserting the locking protrusion on the front side of the lock from the groove and performing the locking operation, it was possible to lock the space between the glass plates using the respective locking protrusions on the front side and the rear side. As a result, there is no need to interpose a conventional U-shaped frame element below the glass plate, which makes it possible to utilize the interior more widely, and provides an excellent visual experience.

○C Since the insert lock is embedded in the cutting gap and the sliding gap of the glass plate and only the locking protrusion on the rear side is operated by locking, not only can the locking stroke be shortened, but also there is some dimensional difference in the rail spacing. It was possible to install it even if there was a problem.

○D When unlocking, unlike the wire spring of Utility Model Publication No. 33-14966, due to the configuration in ○B above, the locking protrusion on the front side is pulled out from the groove of the holding hole on the front side and the lock is inserted. can be taken out. As a result, there is an advantage that there is nothing protruding from the front side of the glass door even when the door is unlocked.
