Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a door lock that is installed with the lock body inserted inside a frame material such as aluminum sash.
In particular, it relates to improvements in its mounting structure.

[Conventional technology]

The conventional mounting structure for this type of door lock is the 7th one.
There are some as shown in Figures a to c. That is, a
, a mounting piece 15 is welded to the inner surface of the frame material 2 into which the lock body 1 is inserted, and the upper and lower ends of the lock body are screwed to this mounting piece. A plate 16 is provided, and the upper and lower ends of the lock body 1 are applied from the outer surface of the frame material and fixed with screws. In c, the upper and lower ends of the lock body 1 are placed against the inner surface of the frame member 2 and fixed with screws.

[Problem that the invention attempts to solve]

By the way, in the mounting structure shown in Figures a and b, it is necessary to weld the mounting pieces or to provide a back plate of approximately the same length as the frame material, which is time-consuming and increases costs. However, there was also the problem that the opening surface in the frame material was large. In addition, in c, the entire lock including the upper and lower ends is inserted into the frame material, so for example, first insert the lock into the frame material from the upper end, shift it slightly upward, insert the lower end, and then position it in the state shown in the figure. In order to do this, the frame material needed to have a depth that was considerably deeper than the depth of the lock body, and there was a problem in that it could not be installed with a frame material that was about the same size as the lock body. Furthermore, this mounting structure cannot be applied even in cases where the lock body cannot be moved up and down (see FIG. 1).

Therefore, the purpose of this invention is to eliminate the need for a mounting piece or back plate on the frame side, and to provide a secure lock even when the depth of the frame is at least as small as possible, and even when the lock body cannot be moved vertically. The purpose is to provide a door lock that can be installed.

[Means for solving problems]

In the door lock according to this invention, a mounting piece is provided on the lock body side, and the method of providing the mounting piece is ingenious. That is, in this invention, in a door lock that is installed with the lock body fitted inside a frame material such as an aluminum sash, a mounting piece having a mounting screw hole at one end is bent and the other end is bent. This mounting piece locks to the main body so that it can be raised and lowered, and the mounting piece can be placed in a prone position with one end with a threaded hole facing down in the depth direction of the lock main body, and in a prone state where it passes through the opening of the lock main body and is attached to the inner surface of the frame material. It is designed so that it can take a standing state.

[Effect]

As mentioned above, since the mounting piece is provided on the lock body side, no mounting member is required on the frame material side. In addition, since the lock body can be inserted into the frame material with the mounting piece lying down, the opening size of the frame material can be made smaller, and there is no need to move the lock body vertically and insert it into the frame material alternately. Therefore, even if the depth dimension of the frame material is the same as that of the lock body, it can be installed.

〔Example〕

Figures 1 to 3 show an embodiment of the door lock according to this invention together with its installation procedure, and are an example of application to a sliding door lock. To explain the general structure of the lock body 1, numeral 3 denotes a rotatable locking piece, which is connected by a pin 4a to a retractor 4 which can be slid by operating an operation knob (not shown). 5 is a hub with a gear that meshes with a plurality of through holes formed in the retractor 4;
It can be operated by a cylinder (not shown) provided on the opposite frame member side. A frame material 2 such as an aluminum sash is formed with a through hole 2b into which the protruding end of the hub 5 is inserted, outside the through hole 2a for the locking piece 3 to move in and out. The door is locked and cannot be moved. 2c is a notch for attachment of the lock body 1. Reference numeral 6 denotes a mounting piece which is an important part of this invention, and is used in this example to fix the upper part of the lock body. This mounting piece has a screw hole 6a for the mounting screw 7 at one end, and is movably locked to the lock body 1 at the other end 6b bent at a substantially right angle.

To explain in more detail according to FIG. 2, the other end portion 6b is composed of a narrow portion A and an enlarged portion B as shown in the figure, and is inserted into the through hole 1b formed in the case side wall or lid 1a of the lock body 1. The narrow part A is inserted through the lock body 1, and the enlarged part B locks the lock body 1 to prevent it from slipping out inward. As shown in the figure, the through hole 1b has a corresponding enlarged portion 1c at its lower end into which the enlarged portion B can be inserted. Reference numeral 8 denotes an auxiliary metal fitting used to fix the lower part of the lock body 1, and has an enlarged part 8a at one end bent at a substantially right angle (see Fig. 3). The other end 8b is made to protrude outward from a through hole 1d formed in the case side wall or the lid 1a of the lock body 1 to prevent the part 8a from coming off. Reference numeral 9 denotes a tightening screw that is inserted through the other end 8b and loosely screwed into a screw hole 1e provided in the case side wall or the lid 1b. Note that 1f is a threading hole for a long seat mounting screw, and a corresponding through hole 6c is formed in the mounting piece 6. 1g is an upper fixing piece provided on the case side wall or an extension of the lid 1a, and is applied to the outer surface of the frame 2 when the lock body 1 is housed within the frame 2.

To install the lock body 1, as shown in Figure 1a, first insert the lower part into the frame material 2 while fitting the tightening screw 9 into the narrow notch 2d connected to the mounting notch 2c. Then, insert the upper part. In this case, the mounting piece 6 is attached to the lock body 1 as shown in the figure.
Leave it in a prone state in the depth direction. After fitting, correct the slight vertical deviation and first tighten the tightening screw 9.
is tightened, the face plate of the frame member 2 is sandwiched between the auxiliary metal fitting 8 and the lock body 1, and the lower part is fixed. The upper part is b
As shown in the figure, raise the mounting piece 6 with your fingertips so that it stands up along the inner surface of the frame material 2,
The installation is completed by inserting the upper fixing piece 1g applied to the outer surface of the frame member 2 and screwing the mounting screw 7 into the screwing hole 6a as shown in Fig. c.

In this example, the lower part of the lock main body has a mounting structure using an auxiliary metal fitting, but this lower part can also be fixed using the mounting piece 6 like the upper part.

5 and 6 show other embodiments,
The reference numeral 10 indicates a mounting piece corresponding to the mounting piece 6 in the above embodiment. The mounting piece 10 is bent into a step-like shape as shown in the figure, and has a screw hole 10a for the mounting screw 11 at one end, and a screw hole 10a at the other end 10b.
As shown, is an enlarged piece. Lock body 1
A locking hole 12 is formed in the side wall of the case or the lid body, and the mounting piece 10 is locked in the enlarged piece 10b so that it can be raised and lowered. This locking hole 12 has an enlarged piece 10
It consists of a substantially circular hole 12a having a size that allows rotation, and a rectangular hole 12b connected thereto, and the width of this rectangular hole 12b is made approximately equal to the thickness of the mounting piece 10. Reference numeral 13 denotes an upper fixing piece of the lock body 1, which has a screw hole 13a for the mounting screw 14, and a frame member 2.
applied to the inner side of

To install this lock body, the mounting piece 10 is laid down in the depth direction of the lock body 1 as shown in FIG. along the inner surface of the frame material and fixed with mounting screws 14. In this case, since there is no fixing piece in the lower part, it is easy to fit the lock body into the frame material and set it at a predetermined position, and the frame material does not require a large dimension in the depth direction. Furthermore, the size of the mounting notch 2c formed in the frame member 2 can be made smaller accordingly. If the upper fixing piece 13 is fixed by the mounting screw 14 or thereafter, if the attachment piece 10 is released from the prone position, the attachment piece 10 will collapse under its own weight into the opening of the lock body as shown in FIG. 5b. , and stands up along the inner surface of the frame material 2. Then, the installation is completed by screwing in the installation screws 11. To hold the mounting piece 10 upside down, use the hole formed in the frame material 2 for inserting the mounting screw 11, or insert the tip of a screwdriver into the insertion hole formed on the front surface of the lock body. It is possible to adopt measures such as retaining the information.

In this example, the upper part has a structure for fixing the fixing piece 13, but the mounting piece 6 of the above-mentioned first embodiment may also be adopted.

[Effect of idea]

As detailed above, the door lock according to this invention uses a mounting piece that lies down in the depth direction of the lock body when it is inserted into the frame material, and that stands up along the inner surface of the frame material after it is inserted. Because of this, there is almost no need to move the lock body vertically during installation, and it can also be installed inside a frame with a small depth dimension, and the notch for installation in the frame can be made smaller. Furthermore, unlike conventional door locks, there is no need to provide a mounting piece or a back plate on the frame material side, and a door lock that can be securely mounted can be provided.
