DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a mounting member for an imposition lock.

[0002]

2. Description of the Related Art As an imposition lock fixed along the surface of a door, a lock described in Japanese Utility Model Laid-Open No. 5-19462 is conventionally known. In this conventional example, the imposition lock consists of an attachment member and a lock body, and fixing to the door is performed by firstly
After fixing the mounting member to the door surface with a screw or the like, the lock body is fastened to the mounting member.

[0003]

However, the above-mentioned prior art has the following disadvantages. That is, first, in the above-mentioned conventional example, since it is necessary to use screws or tapping screws to attach to the door, installation is troublesome, and there is an obligation to return to the original state at the end of the contract, for example, a rental house, etc. Has a problem that it cannot be used.

[0004] Such a problem can be solved by, for example, fixing the mounting member in the above-mentioned conventional example with an adhesive tape or the like. Safety is reduced. In particular, in the case of an imposition lock fixed to the door surface, when the door is to be opened in the locked state, a force in the peeling direction is generated at the adhesive interface between the imposition lock and the door. However, since the adhesive force of the adhesive tape is extremely low in the cleavage direction, the holding strength of the imposition lock to the door is weak, and the locking effect by installing the imposition lock cannot be expected.

[0005] Further, in the case of a door such as a so-called flash door in which a door is filled with a filler material in a frame body, for example, a frame member, and the surface layer is covered with an appropriate surface material, the door can be fastened with a wood screw or the like. Since the region is only the portion corresponding to the frame member, the mounting member cannot be securely fixed, and the holding strength to the door is reduced.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned drawbacks, and provides a mounting member for an imposition lock which can be easily installed on a door and has a high holding strength for the imposition lock on the door. The purpose is to do.

Another object of the present invention is to provide an imposition lock capable of firmly fixing an immobilization lock to a door even when an adhesive means cannot be used because a flange is projected from a vertical frame. The present invention provides a structure for mounting to a door.

[0008]

According to the present invention, the object is to provide a lock mounting portion 2 for fixing an imposition lock 1, and a lock mounting piece 4 fixed to a surface of a door 3, and a lock mounting piece 4. Is formed by bending an edge portion of the door 3 and has an end face fixing piece 5 fixed to the open end face 3a of the door 3 to form an L-shaped cross section. This is achieved by providing a mounting member 10 of an imposition lock provided with a locking claw 8 which can be locked to a flange 7 formed on the third vertical frame 6.

When the imposition lock 1 is mounted on the door 3 via the mounting member 10 and the door 3 is to be opened in the locked state, a peeling force from the door 3 is applied to the mounting member.
The peeling force acts substantially parallel to the open end face 3a (kiguchi) of the door 3, as shown by an arrow A in FIG. 3, and rotates the mounting member 10 about the edge B on the side away from the open end face 3a. And

In the present invention, the end face fixing piece 5 is
Is fixed to the open end face 3a, thereby bearing the resistance against the rotational force as the shear resistance F along the open end face 3a. By bearing the peeling resistance force as the shearing resistance force F, the stress load on the lock mounting piece 4 is reduced. For example, even if the lock mounting piece 4 is fixed using the adhesive tape 11, sufficient holding strength can be obtained. Can be Further, a shearing force is applied to the end face fixing piece 5 side, and the adhesive tape 11 has a low resistance in the cleavage direction, but shows a high resistance in the shearing direction. It is also possible to fix using.

As a result, if the mounting member 10 according to the present invention is used, the imposition lock 1 can be fixed to the door 3 using only the adhesive tape 11, and the mounting operation is simple.
In addition, necessary holding strength can be secured.

The locking claw 8 is used to bend when it is fixed to a flash door or an aluminum door or the like in which the flange 7 is formed on the vertical frame 6. That is, in these doors 3, the end face fixing pieces 5
The adhesive tape 11 cannot be used because it cannot be brought into close contact with the open end face 3 a of the door 3. However, by locking the locking claw 8 to the flange 7, the flange portion can exhibit shear resistance. . As a result, regardless of the type of the door 3, the imposition lock 1 is moved to the door 3 while maintaining a high holding force.
, The versatility is increased.

The locking claw 8 is locked to the flange 7 by being bent toward the open end face 3a side of the door 3, but is locked to the locking side 8a.
Is a sloping surface that gradually moves away from the lock mounting piece 4 as it goes to the front end, regardless of the thickness of the flange 7,
a can be reliably locked to the flange 7.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a mounting member 10 of an imposition lock has a lock mounting piece 4 and an end face fixing piece 5 obtained by bending the tip of the lock mounting piece 4 by 90 °. To form an L-shaped cross section. The mounting member 10 can be formed by, for example, bending a stainless steel plate or the like, and a lock mounting portion 2 is formed at the center of the lock mounting piece 4.

The lock mounting portion 2 is formed by applying burring to four corners of a lock fixing seat surface 2a formed by drawing a central portion of the lock mounting piece 4 to form a screw hole 2b. As shown in FIG. 3, the lock fixing seat surface 2 a can secure a sufficient tightening length of the mounting screw 12 and has such a degree that the dead bolt 1 a of the imposition lock 1 does not interfere with the door stop 9 a of the door frame 9. Set to height.

Further, a double-sided adhesive tape 11 is attached to the back surface of the lock mounting piece 4. The adhesive tape 11 is arranged on both side edges of the lock mounting piece 4 as shown by hatching in FIG. The double-sided adhesive tape 11 has a thickness sufficient to absorb the step of the vertical frame 6 so as to be adaptable to the door 3 in which the surface of the door 3 and the surface of the vertical frame 6 are not flush with each other, such as a flash door. In addition, it is desirable that the adhesive be attached to a region corresponding to the vertical frame 6, that is, a portion other than the boundary with the end face fixing piece 5. In addition, the lock attachment piece 4 can be provided with a fastener insertion hole 4a such as a screw or a wood screw, and the fastener insertion hole 4a has a screwable portion only near the door edge, such as a flash door. It is arranged only near the end face fixing piece 5 so as to be able to correspond to the door 3.

On the other hand, a locking claw 8 is formed in the vicinity of the center of the end surface fixing piece 5 in the vertical direction (vertical direction in a state where it is fixed to the door 3) and in the vicinity of the boundary with the lock mounting piece 4. As shown in FIG. 4, the locking claw 8 is formed into a protruding piece extending in the vertical direction from the base 8 b by punching out the periphery except the base 8 b and separating from the surrounding fleshy part. Is the locking side 8a. The locking side 8a is inclined so as to gradually move away from the lock mounting piece 4 as it goes from the base 8b to the free end, and the base 8b of the locking side 8a substantially matches the bottom surface 4b of the lock mounting piece 4. I do.

In the illustrated example, the locking claw 8 is attached to the base 8
Although two protruding parts are provided up and down from the bridge part 13 which provides b, the number can be changed as appropriate. The punching portion 14 forming the free end 8c of the locking claw 8 has a width dimension w that allows the tip of a flathead screwdriver to be pryed.

Further, a fastener insertion hole 5a is formed in the end surface fixing piece 5, and a double-sided adhesive tape 11 is attached thereto. Fastener insertion hole 5a and double-sided adhesive tape 1
1 is arranged in a region deviated from the locking claw 8 to the free edge side of the end face fixing piece 5.

Next, a method of using the mounting member 10 will be described. The mounting member 10 is in a state in which the locking claw 8 is not bent,
In other words, the locking claw 8 and the general surface of the end face fixing piece 5 are supplied in the same plane. In use, first, the mounting member 10 is fixed to the open end of the door 3. Door 3 of mounting member 10
The method of fixing to the door 3 differs depending on the type of the door 3, and the wooden door 3,
Alternatively, when the sectional shape of the open end is rectangular, as in the case of the iron door 3, as shown in FIG. 3, the double-sided adhesive tape 11 attached to the back surface of the lock mounting piece 4 and the end face fixing piece 5 is used. Utilizing the end face fixing piece 5 on the open end face 3a of the door 3,
After fixing the lock mounting piece 4 to the surface of the door 3, the imposition lock 1 is fixed to the lock mounting piece 4. The imposition lock 1 is an operation unit 1b such as a knob.
Can be used to move the dead bolt 1a forward and backward. The fixing to the mounting member 10 can be performed by attaching the mounting screw 12 passing through the mounting hole 1c of the imposition lock 1 to the lock fixing seat surface 2a. Screwed into the screw hole 2b. When a wood screw or the like is used for fixing the mounting member 10 to the door 3, the lock mounting piece 4 or the end face fixing piece 5
In order to prevent screw traces or the like from remaining on the door 3 after the imposition lock 1 is removed, the fastener insertion holes 4a and 5a formed on the door can be used.

The illustrated example shows a state in which the imposition lock 1 is fixed to the door 3 using only the adhesive tape 11, and when the imposition lock 1 is in the locked state, an attempt is made to open the door 3. A force in the direction of arrow A is applied to the dead bolt 1a,
Peeling force from the door 3 is generated on the mounting member 10, but the adhesive tape 11 fixing the end face fixing piece 5 to the open end face 3a of the door 3 has a high resistance in the shearing direction, so that it is easily peeled. Never do.

FIG. 5 (a) shows a flash door, and FIG. 5 (b)
Shows an example of application to an aluminum door. In this embodiment, the flash door has a frame in which a wooden frame member 15 is framed in a rectangular shape, a filler 16 filled in the frame, and a vertical frame 6 fixed to the open end surface 3a. The frame 6 is provided with a flange 7 protruding from the door frame 9 side. When fixing the imposition lock 1 to the door 3, first, the lock mounting piece 4 is attached to the surface of the door 3 by the adhesive tape 11 such that the back surface of the end face fixing piece 5 of the mounting member 10 is brought into contact with the end face of the flange 7. After fixing, the locking claw 8 is bent from the base 8b to the inside of the door 3.

Since the lock attachment piece 4 is provided with the fastener insertion hole 4a at a position where a wood screw or the like works on the frame member 15,
The fixing piece 4 can be fixed using a wood screw or the like by using the fastener insertion hole 4a. However, in order to prevent a screw mark or the like from being left on the door 3 after the imposition lock 1 is removed. It is desirable to fix with only the adhesive tape 11.

When the locking claw 8 is bent, a predetermined point on the locking side 8a abuts on the ridge line of the flange 7 to lock the flange 7 and inhibit movement in the shearing direction. The bending of the locking claw 8 is performed by punching out a free end 8 c of the locking claw 8.
This can be easily performed by inserting a tip of a flathead screwdriver or the like into the device and then prying in the direction of arrow B in FIG. Since the locking side 8a of the locking claw 8 is inclined in the direction of the free end 8c, if the thickness of the flange 7 is smaller than the distance between the free end and the base end of the locking side 8a, As shown in FIG. 4, even if the thickness d of the flange 7 changes, the locking side 8 a can always be locked to the flange 7.

In the example shown in the drawing, a wood screw 17 is also used for fixing the end face fixing piece 5, but it is used to prevent a screw mark or the like from being left on the door 3 after the imposition lock 1 is removed. You don't have to.

Although the method of fixing the mounting member 10 using the locking claw 8 has been described by taking the case of a flash door as an example, also in the case of an aluminum door, as shown in FIG.
It can be fixed in exactly the same way.
