[Detailed description of the invention]

[0001]

This invention relates to a locking device for a door and a door.
The present invention relates to a structure for attaching to any of the support frames.

[0002]

2. Description of the Related Art Hitherto, various means for attaching a locking device to a door or a supporting frame thereof have been proposed, and these means can be properly used depending on the use condition of the locking device.
As one of the frequently used means, there is a technique of sandwiching a door or a plate member of a support frame from inside and outside.

[0003]

[Problem to be Solved by the Invention] Even in the technology to be sandwiched, a proposal for an ingenuity that can realize further easiness of use is constantly demanded. Thus, in the present invention, the locking device is advanced with the case member in the longitudinal direction of the device.
And a holding member connected to the case member via an operating bolt, and a plate member such as a door can be held from inside and outside by moving the operating bolt forward . Thus, it is an object of the present invention to make it possible to attach the locking device to the door without increasing the size of the door in the thickness direction.

SUMMARY OF THE INVENTION The present invention relates to a locking device.
It relates to improvement of the mounting structure.

This invention has a virtual axis in the longitudinal direction.
A locking device, wherein the device is parallel to the axis,
A top plate, an opposing side wall connected to the top plate, and between the opposing side walls.
A case member having a continuous end wall;
An operation for moving forward in the axial direction located on the outer surface of the end wall
The case member is slidable in the same direction via bolts.
And a girder holding member. The case member pair
A guide projection is provided on the outer surface of each side wall,
The holding member is located at a predetermined angle with respect to the top plate,
The distance from the top plate as it goes in the forward direction of the holding member
Has an inclined sliding contact surface that reduces
When the holding member is advanced in the forward direction by
The holding member is moved by sliding of the sliding contact surface with respect to the guide projection.
There is provided an action edge for bringing the table close to the top plate .

[0006]

The locking device having such a structure is used by sandwiching a door member to which it is attached and a plate member of any of its support frames such that the top plate is positioned outside the door and the holding member is positioned inside the door. When the bolt is tightened, the holding member is inclined
The working edge having the sliding contact surface slides on the guide protrusion and approaches the top plate. Thus, the top plate and the holding member can hold the plate member, and the locking device can be attached to the plate member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the mounting structure of the locking device according to the present invention will be described below with reference to the accompanying drawings.

[0008] Figure 1 is a cross-sectional view of a locking device 1 provided with a mounting structure according to this invention, locking device 1, it length
A virtual axis X of the direction, attached to the plate member 2A of the door 2, there the door 2 against the support frame 3 in a state of locking. The locking device 1 includes a case member 5, a latch bolt 6 housed in the case member 5 so as to be slidable in the direction of the axis X , a sandwiching member 7 located outside the case member 5, and members 5 and 7. Thea configure the operation bolt 23 interposed advanced to the axis X
You. The latch bolt 6 is inserted into the bolt hole 8 of the support frame 3.
The locking device 1 enters a locked state or an unlocked state.

The case member 5 has a mounting hole 1 for the plate member 2A.
A top plate 13 which abuts from the outside around 0 and has a knob 12 insertion hole 11 at the center, and a plate member 2A connected to the top plate 13
A side wall 14 located in the inside, screw holes 1 continuous to the side wall 14
5 and the end wall 16 having, and a side wall 14 and end walls 16 and parallel to the contiguous <br/> top plate to a bottom plate 17.

The holding member 7 is provided with the top plate 13 and the plate member 2.
A for holding the A, the side wall 20 and the end wall 21
The operation bolt 23 inserted through the through hole 22 of the end wall 21 is screwed into the hole 15. A clearance 24 is provided between the holding member 7 and the end walls 21 and 16 of the case member 5.
There are, tightening the operation bolt 23, the clamping member 7 is moved to the right.

[0011] latch bolt 6 is divided into a front 6A and rear 6B, the Bol front 6A is in a state of crossing the bolt holes 8
The rear portion 6 is supported via a support shaft 25 facing the substantially central portion of the through hole.
Pivotally connected to B, and is urged in the clockwise direction by the biasing spring 26. At the rear end of the rear part 6B, the axis X
A biasing spring 28 whose one end is pressed against the end wall 16 is accommodated therein, and the latch bolt 6 is biased to the right, that is, to advance and enter the bolt hole 8. The rear part 6B is provided with the case member 5 through the insertion hole 11.
When the knob 12 is operated to the left, the latch bolt 6 is retracted against the biasing spring 28, and the front portion 6A is retracted from the bolt hole 8. The phantom line in the figure indicates the position of the front portion 6A of the retracted latch bolt 6 and the position of the knob 12. When the front portion 6A retreats and turns clockwise by a predetermined angle, a stopper mechanism (not shown) acts and stops. The front part 6A is connected to the rear part 6B.
At the same time, it is urged by the urging spring 28, and presses against the wall surface 3A of the support frame 3 to keep the latch bolt 6 in the retracted position. Can be locked.

FIG. 2 shows a locking device 1 holding a plate member 2A.
The latch bolt 6 is in a retracted position.
Thus, the front part 6A is in a state of turning. The side of the case member 5

FIG. 3 is a partially exploded perspective view of the locking device 1. In the figure, the door 2 is open with respect to the support frame 3,
As a result, the front part 6A comes off from the supporting frame side wall 3A with which the contact is made, and the latch bolt 6 is in an advanced state. The locking device 1 is symmetrical about the center line CC , and the side wall 14 of the case member 5 has a pair of opposed side walls 14A and 14B.
It is composed of The side wall 20 of the holding member 7 is constituted by a pair of side walls 20A and 20B opposed to each other. In order to mount the device 1, the case member 5 accommodating the latch bolt 6 is fitted from the outside into the through hole 10 of the plate member 2A, and then the case member 5 is fitted inside the plate member 2A.
And a clamping member 7 from the rear is fitted with respect to each other of the inclined slope 3
0 is brought into contact with the working edge 32. If screwed operation bolt 23 in this state, the clamping member 7 is moved upward, it is possible to sandwich the plate member 2 A together with the top plate 13.
Inclined slope 30 is a guide means for moving the clamping member 7 upwardly, and a means for supporting the pressure when clamping the plate members 2A, large pressure the larger the contact area with the working edge 32 Although withstand, instead of guide projections 31 for forming the inclined slope 30 in a cylindrical, it acts on the side surface of the cylinder
It is also possible for the rim 32 to abut. The locking device 1 is used by being attached to a door of a distribution board, a distribution board, or the like, for example.

[0014]

The mounting structure of the locking device according to the present invention has an operating bolt that moves forward along the longitudinal axis of the device, and simultaneously slides forward in the axial direction and the top plate side. The use of a possible clamping member does not affect the size of the locking device in the direction from the outside to the inside of the door. Never.
