DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle locking device for locking a door or the like, and more particularly, to a handle locking device having a function of sufficiently engaging a handle body and a receiving member without loosening.

[0002]

2. Description of the Related Art As a device for locking a door or the like, a handle locking device has been proposed. This handle device
The handle body and the receiving member have a basic configuration, and the handle body is rotatably engaged with the receiving member. An example of such a conventional handle locking device will be described with reference to the drawings.

[0003] The handle locking device 100 includes a handle portion 101a.
And a receiving member 102 having a receiving hole 102a rotatably inserted into the rotating shaft 101b and used to be fixed to the target door 200.

The rotating shaft portion 101b has a screw hole 101c for screwing a bolt 107. The bolt 107 is provided with a stopper plate 103 for locking the door 200 and the door frame 201, a spacer 104, and a washer 105. And a spring washer 106, and are screwed into the screw hole 101c of the rotating shaft portion 101b.

In the handle locking device 100 having the above structure, the stopper plate 103 and the handle body 101 are integrated with each other by the fastening force of the bolt 107, and when the handle 101 is pulled out from the receiving member 102, a force acts. The stopper plate 103 catches on the end surface of the receiving member 102 on the bolt 107 side, and resists this.

[0006]

In the conventional handle locking device 100, the stopper plate 103 rotates along the end surface of the receiving member 102 on the bolt 107 side according to the rotation of the handle portion 101a, and the door 200 and the door 200 are closed. When the stopper plate 103 is repeatedly rotated, the screwing between the bolt 107 and the screw hole 101c is loosened, resulting in an extreme play of the handle main body 101 and the receiving member 102. There is a problem that drop out from the.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a handle locking device capable of sufficiently engaging a handle main body with a receiving member and preventing the rattle of the handle main body and falling off.

[0008]

According to the present invention, there is provided a handle body having a handle portion and a rotary shaft portion which rotates in accordance with the rotation of the handle portion and has a screw hole for fixing a stopper plate in an axial direction. And a receiving member having a receiving hole into which the rotating shaft portion is inserted, wherein the rotating shaft portion is bored in a radial direction from the screw hole toward the surface of the rotating shaft portion. The receiving member has a groove provided in a circumferential direction on a peripheral surface of the receiving hole, is inserted into the through hole, and has one end loosely fitted in the groove. Embedded screw to be screwed into the screw hole, and the thread into which the embedded screw is screwed.
To fix the stopper plate screwed into the
And the embedded screw , respectively ,
When the bolt moves according to the screw insertion into the screw hole
In addition, there is provided a handle locking device having a contact portion at its tip for pressing and moving the other end of the pin in the radial direction of the screw hole (claim 1).

In this means, one end of the pin is loosely fitted in the groove while the pin is inserted into the through hole, so that the relative movement of the handle body and the receiving member in the axial direction is disabled. On the other hand, since the groove is provided in the circumferential direction of the receiving hole , the pin can rotate along the groove, and the rotation shaft portion of the handle main body regardless of the presence of the pin It can rotate within the receiving hole .

Therefore, when the handle is rotated, the stopper plate is rotated in conjunction with the rotation of the handle, so that the door can be locked and unlocked. At this time, even if the rotation of the rotation shaft portion is repeated and the bolts for fixing the stopper plate and the screw holes are loosened,
Since the handle body and the receiving member are engaged by the pin, they are not affected by the loosening of the bolt,
Problems such as extreme rattling of the handle body and falling off from the receiving member do not occur.

Further, in the present invention, the embedded screw is provided with the contact portion at a tip thereof. This abutment is
The embedded screw is screwed into the screw hole, that is, as the screw is screwed into the screw hole and screwed toward the screw bottom, it comes into contact with one end of the pin and presses it radially, It can be moved towards the groove. Therefore,
If the embedded screw is screwed into the screw hole, the pin can be loosely fitted into the groove, and after the loose fit of the pin, the other end of the pin contacts the side circumference of the embedded screw. As a result, the pins are prevented from falling off.

In the present invention, the screw holes do not necessarily have to have the same diameter over the entire length. For example, a small diameter portion to which the embedded screw is screwed, a large diameter portion to which a bolt for fixing the stopper plate is screwed,
(Claim 2). In this case, there is no problem even if the axes of the small diameter portion and the large diameter portion are slightly shifted from each other.

[0013] In the present invention, an embedding piece without a thread for screwing into the screw hole may be used in place of the embedding screw (claim 3). Since this embedding piece has no thread, the pin cannot be moved in the radial direction by screwing into the screw hole like the embedding screw, but the bolt for fixing the stopper plate is not used. By being pressed by the screw insertion, the pin is moved toward the bottom of the screw hole, and the pin can be pressed in the radial direction.

That is, in accordance with the pressing force by screwing in the bolt, the abutting portion at the tip of the embedding piece abuts one end of the pin and presses it radially, thereby moving toward the groove. Can be moved. When this embedded piece is adopted, it is not always necessary to provide the screw holes uniformly in the screw holes (claim 4). This is because the embedded piece does not have a thread, so that the screw hole does not need to be threaded at a position where the embedded piece is inserted.

[0015]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a partially cutaway view of a handle locking device A according to the present invention, showing a state in which some parts are disassembled. FIG. 2 is similar to FIG.
FIG. 3 is a diagram showing an aspect in which the respective components are assembled. In FIGS. 1 and 2, screw holes such as the screw holes 1c are omitted.

The handle locking device A includes a handle body 1
And the receiving member 2, and the embedded screw 8 as the main configuration,
Further, it includes a stopper plate 3, a spacer 4, a washer 5, a spring washer 6, and a bolt 7.

The handle main body 1 has a handle portion 1a and a rotating shaft portion 1b provided integrally with the handle portion 1a and rotated by rotation of the handle portion 1a. The rotating shaft portion 1b is provided with a screw hole 1c opened at the end thereof,
Further, a through hole 1d is provided at a position in the middle of the screw hole 1c from the screw hole 1c to the side peripheral surface of the rotating shaft portion 1b in the radial direction.

The receiving member 2 comprises a rotating shaft 1 of the handle body 1.
The receiving hole 2a is rotatably inserted into the receiving hole 2a, and a groove 2b is formed in a circumferential surface of the receiving hole 2a. ◆
The groove 2b is provided such that when the rotating shaft portion 1b of the handle body 1 is inserted into the receiving hole 2a, the position thereof is substantially the same as the through hole 1d provided in the rotating shaft portion 1b. . The groove 2b does not necessarily need to be provided over the entire circumference of the receiving hole 2a. That is, since the stopper plate 3 is not necessarily required to rotate 360 degrees, the stopper plate 3 falls within the necessary rotation range (within the rotation range of the rotating shaft 1b).
It is sufficient if provided accordingly.

A cylindrical pin 9 is inserted into the through hole 1d . This pin 9 is a pin whose one end can be loosely fitted in the groove 2b. When the rotating shaft 1b is to be inserted into the receiving hole 2a, the through-hole 1 is formed so that the one end is not in the way.
d, and the other end protrudes into the screw hole 1c (FIG. 1). In addition, these through holes 1d and pins
9 or more combinations may be provided.

The embedding screw 8 is of a substantially cylindrical shape having a threaded surface required for screwing with the screw hole 1c, and has a tapered tip at its tip. Contact 8
a. The abutting portion 8a radially presses the other end of the pin 9 having the other end protruding into the screw hole 1c in accordance with the insertion of the embedded screw 8 into the screw hole 1c, and presses one end of the pin 9. This is for making it move so as to be loosely fitted in the groove 2b. ◆ Embedded screw 8 is screw hole 1
In order to facilitate the screwing to c, those having a hexagonal hole or a square hole are preferable.

Next, the handle locking device A of the present invention is shown in FIG.
The process of assembling from the embodiment of FIG. 2 to the embodiment of FIG. 2 will be described. FIG. 3 is an enlarged view of a main part of the handle locking device A in the assembling process. ◆ In the embodiment of FIG.
The rotating shaft 1b of the handle body 1 is inserted into the receiving hole 2a of the receiving member 2.
And the pin 9 is not loosely fitted in the groove 2b, and the other end of the pin 9 projects into the screw hole 1c.

In the handle locking device A, the embedded screw 8 is screwed into the screw hole 1c before the stopper plate 3 is screwed into the screw hole 1c by the bolt 7. The embedded screw 8 is, for example, a screw hole 1c with a hexagon wrench or the like.
And screw deeply into it. ◆ According to the insertion of embedded screw 8,
The contact portion 8a comes into contact with the other end of the pin 9 (FIG. 3). Then, the pin 9 moves in the groove 2b direction (radial direction) so as to slide on the contact portion 8a having a substantially tapered shape (FIG. 3).

When the embedded screw 8 is further inserted, the pin 9
Will move to a position where one end thereof is loosely fitted in the groove 2b and the other end does not project into the screw hole 1c (FIG. 2). At this time, the other end of the pin 9 is in contact with the side circumference of the embedded screw 8, so that the pin 9 does not return into the screw hole 1c and come off. ◆ After this, stopper plate 3
The bolt 7 is screwed into the screw hole 1c via the spacer 4, the washer 5 and the spring washer 6, and the assembly is completed (FIG. 2).

In the assembled handle locking device A, the presence of the pin 9 makes the relative movement of the handle main body 1 and the receiving member 2 in the axial direction impossible. On the other hand, the groove 2b is
The pin 9 is allowed to rotate along the groove 2b. Therefore, the rotating shaft 1b
Can rotate in the receiving hole 2a, and the stopper plate 3 can rotate in conjunction with the rotation of the handle portion 1a. ◆ Because the handle body 1 and the receiving member 2 are engaged by the pin 9, the bolt which was a problem of the conventional product
It is not affected by the looseness of 7, and the handle body 1 is extremely rattled and does not fall off.

Next, another embodiment of the handle locking device A will be described. In the above-described embodiment, the shape of the abutment portion 8a of the embedded screw 8 is substantially tapered. However, if the pin 9 can be moved in the radial direction, another shape such as a hemisphere is used. There may be. Also,
The other end of the pin 9 is also easily moved by the contact portion 8a,
For example, it may be hemispherical.

The screw holes 1c do not necessarily have to have the same diameter, and if they have different diameters, they need not have the same core. For example, as shown in a screw hole 1c 'shown in FIG. 4, a small diameter portion M for screwing the embedded screw 8 and a large diameter portion N for screwing the bolt 7 are offset from each other. It may be provided.

Also, instead of the above-mentioned embedded screw 8,
An embedding piece having no threading on the side circumference may be used. FIG.
This is an example in which an embedding piece 8a ' which is different from the embedding screw 8 only in that there is no thread in the side circumference is employed. Embedded piece 8 '
The contact portion 8a has a contact portion 8a ' similar to the contact portion 8a described above, and the pin 9 can be loosely fitted into the groove 2b by the contact portion 8'.

However, the embedded piece 8 ′ itself has the screw hole 1.
c, so that the rear end thereof is pressed by screwing a bolt 7 ′ for fixing the stopper plate 3, thereby exerting a pressing force for moving the pin 9 in the radial direction. Become. FIG. 7 shows such an embedded piece 8
It is a partially broken view at the time of assembling of the handle device A 'when "1" is adopted. Since the embedding piece 8 'is not screwed with the screw hole 1c, it can be moved in the screw hole 1c. If the extreme movement is allowed, the other end of the pin 9 will not come into contact with the side circumference of the embedded piece 8 ', and there is a risk that the pin 9 may fall into the screw hole 1c. Therefore, in order to limit the extreme movement of the embedded piece 8 ′ by the bolt 7 ′,
7 'has a length such that its tip is close to the embedded piece 8'.

Since the embedding piece 8 'does not need to be screwed into the screw hole 1c, the whole shape can be freely changed as compared with the embedding piece 8 described above. For example, it may be spherical as a whole. Also, the embedded piece
8 'is not screwed but pushed by the bolt 7' and advances through the screw hole 1c, and does not rotate in the screw hole 1c. Therefore, the contact portion 8a 'does not need to be formed on the entire periphery of the tip of the embedding piece 8', and need only be formed on a part that contacts the pin 9.

Further, when the embedding piece 8 'is adopted,
The screw hole 1c does not need to be uniformly threaded at all positions. That is, since the embedded piece 8 'is not screwed with the screw hole 1c, it is not necessary to thread the screw hole 1c at the position where the embedded piece 8' is inserted.
FIG. 6 is a diagram showing such an example, and the screw hole 1c "
No thread is provided at the position where the embedded piece 8 'is inserted.
