Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a door lock mounting structure that is applied to mounting the main body of the door lock inside a hollow door frame.

Door locks are often attached to doors such as entrance doors, and the most suitable door lock is usually selected from among several door locks with several specifications.

On the other hand, doors have various sizes and shapes depending on the structure and design of the building. The size does not necessarily match well with just the right amount.

Therefore, it may be possible to change the wall thickness of the door frame to match the size and especially the thickness of the door lock body, but changing the wall thickness of the door frame to match the door lock body will unnecessarily reduce the weight of the door frame. This is an undesirable problem because it may cause an increase in the amount of water or an increase in price. On the other hand, if the door frame and the door lock main body are screwed together with a large gap formed between them, there is a problem in that the door lock mounting portion of the door frame becomes depressed, spoiling the appearance.

Therefore, it is possible to interpose a spacer between the door frame and the door lock body, but if a single spacer is inserted, the mounting position of the door lock body will be moved away from the center of the door in the wall thickness direction. In addition, when the door frame and the door lock body are attached by interposing spacers on both sides of the door lock body, the work is very troublesome and time-consuming.

This idea was made by focusing on the problems of the conventional methods mentioned above, and it is possible to install the door lock body inside the door frame very easily and firmly. It is an object of the present invention to provide a door lock mounting structure in which the mounting position of a part can be set at a desired accurate position, for example, at the center position in the wall thickness direction of a door frame.

This invention has a door lock mounting structure in which spacer pieces are interposed in the spaces formed between the hollow inner surface of the door frame and both side surfaces of the door lock body to mount the door lock body within the door frame. The spacer pieces are connected via a connecting piece, and a positioning protrusion is formed on a surface of at least one of the spacer pieces facing the inner surface of the door frame, and a positioning protrusion is formed on the facing surface of the door frame. The door lock mounting hole is provided with a guide portion for guiding the positioning projection to a predetermined position, and the positioning projection of the spacer piece is locked in the door lock mounting hole of the door frame.

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

In FIGS. 1 and 2, 1 is a hollow door frame that constitutes the door, 2 is an outdoor door handle,
3 is the door lock. This door lock 3 has a key insertion protrusion 4 on the outdoor side, a knob 5 on the indoor side, and a door lock main body part 6 that is mounted inside the hollow door frame 1.

Both sides of this door lock body part 6 and the door frame 1
A spacer 10 is interposed between the opposing inner surfaces, and in this state, the door lock 3 and the door frame 1 are fixed by screws 8, 8.

As shown in FIGS. 3 and 4, this spacer 10 is comprised of two spacers that can be interposed in the spaces formed between the opposing inner surfaces of the door frame 1 and both side surfaces of the door lock body portion 6. Piece 11,1
2 are integrated via a flexible connecting piece 13. In this embodiment, spacer piece 1
The wall thickness required for spacer pieces 1 and 12 is
Although this is ensured by providing a rib 14 on one side of each of the ribs 1 and 12, in other embodiments, the spacer piece may have the same thickness over the entire surface without relying on the rib 14. However, in this case, the amount of raw materials used increases and the weight also increases, so it is preferable to ensure the necessary wall thickness with the ribs 14. Furthermore, through holes 15, 15 for screws 8, 8 are formed in the spacer pieces 11, 12,
A positioning protrusion 1 that also serves as a biscuit on one side (lower side in Fig. 3) of the screw throughflows 15, 15.
6 and 16, and an insertion hole 17, 17 for a door lock operating portion is formed in the middle portion of both the through holes 15, 15.

Further, in the spacer 10 according to this embodiment, the spacer pieces 11, 12 and the connecting piece 13 are integrally formed from the same material (for example, a suitably plastic synthetic resin), so that the wall thickness of the connecting piece 13 can be reduced. By doing so, flexibility can be obtained with a small force.

Therefore, when attaching the door lock 3 to the door frame 1 using the spacer 10 shown in FIG.
Bend the connecting piece 13 of the spacer 10 in the direction of the arrow in FIG.
is inserted into the inside of the door frame 1 through the door lock mounting through hole 1a provided on the end face of the door frame 1, and the positioning protrusions 16, 16 formed on the spacer pieces 11, 12
While contacting the guide portions 1d that are continuous with the door lock mounting holes 1b formed on both sides of the door frame 1,
Small radius side corner part 1 of the door lock mounting hole 1b
Then, the door lock main body portion 6 is inserted through the door lock mounting through hole 1a and installed between both spacer pieces 11 and 12 of the spacer 10, and then key insertion protrusions are installed on both sides of the door lock mounting hole 1b. The pedestals 4a and 5a on the 4 and knob 5 sides are brought into contact with each other and fixed with screws 8 and 8, respectively.

In this way, since the spacer pieces 11 and 12 are interposed in each space formed between the inner surface of the door frame 1 and the door lock main body portion 6, the spacer pieces 11 and 12 are provided at predetermined positions in the wall thickness direction of the door frame 1, for example. The door lock 3 can be accurately mounted at the center position, and the mounting portions of the pedestals 4a, 5a of the door frame 1 will not be depressed even when the screws 8, 8 are tightened.

If the expected dimensions of the door frame 1 increase or decrease, a spacer with a thickness corresponding to the size of the space between it and the door lock body 6 (including the case where ribs are used instead) is used. Piece 11,
12, it is possible to use a common door lock 3 even when the type of door frame 1 changes and its expected dimensions differ, which improves the workability of installing the door lock 3 and parts management. It will be possible to realize significant efficiency improvements.

In addition, positioning protrusions 1 are provided on the spacer pieces 11 and 12.
6 and the door lock mounting hole 1 of the door frame 1.
By providing the guide portion 1d in b, positioning when installing the spacer 10 inside the door frame 1 can be done extremely easily and accurately, and in this installed state, the flexible connection Piece 1
Since the repulsive force of 3 is acting, the spacer 10 will not be displaced at all, and the subsequent installation of the door lock body portion 6 can be carried out with great ease.

In addition, in the above embodiment, both spacer pieces 1
1 and 12 are connected by a flexible connecting piece 13 to form an integrated spacer 10, which in a free state extends in one plane as shown in FIG.
Although the spacer 10 is shown as an example in which the connecting piece 13 is bent to form a U-shape as a whole during use,
This invention is not limited to the case where such a spacer 10 is used; for example, as shown in FIGS. It is also possible to use a spacer 10 which is already U-shaped as a whole; among these, the flexible connecting piece 13 may be divided into two parts, as shown in FIG. 5b. . Furthermore, Fig. 6 a, b
As shown in the figure, the spacer 10, which is generally V-shaped as a whole, is used to make it U-shaped inside the door frame 1 so that it can be easily mounted, and at the same time, it is possible to easily operate the spacer 10 when it is installed inside the door frame 1 on both inner surfaces of the door frame 1. It is also possible to obtain an appropriate repulsive force against the object, and all of these embodiments are within the scope of this invention.

As explained above, according to this idea,
In the door lock mounting structure in which the door lock body portion is mounted within the door frame by interposing spacer pieces in the spaces formed between the inner surface of the door frame formed in a hollow shape and both side surfaces of the door lock body portion, the door lock body portion is mounted within the door frame. The spacer pieces are connected via a connecting piece, and a positioning protrusion is formed on a surface of at least one of the spacer pieces facing the inner surface of the door frame, and a positioning protrusion is formed in the door lock mounting hole formed on the facing surface of the door frame. has a guide portion for guiding the positioning protrusion to a predetermined position, and the positioning protrusion of the spacer piece is engaged with the door lock mounting hole of the door sill, making it extremely easy to attach the door lock to the door.
