Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial application field> The present invention relates to a novel lifting lock device suitable for locking a piece of tempered glass door or the like used at a building entrance. .

<Conventional technology> A type of lifting device in which kanuki devices are separately mounted on the upper edge and the lower edge of a door, connected by a link or the like, and one kanuki device is operated simultaneously with the other kanuki device. Dropping devices are known.

However, such a device cannot be used for a single piece of tempered glass door or narrow frame door because a link or the like for connecting the upper and lower cannuki devices is required.

When these doors are locked with kanuki, for example, in the case of a glass door, the upper and lower edges of the door are partially covered with a metal plate or the like, and separate kanuki devices installed inside the door are individually operated with keys. Locking is performed by two operations.

<Problems to be solved by the invention> In the case of a single piece of glass door using tempered glass, exposing the locking device to the door tip portion is not aesthetically pleasing, and two glass doors are installed in a double door. In such a case, since the glass at the door end faces each other, it is impossible to physically install the locking device.

Therefore, locking devices must be installed on the upper edge and lower edge of the door, but as described above, these locking devices are independent of each other in the upper and lower directions. Operation must be performed.

Further, even with a door other than a glass door, for example, in a door having a narrow frame, since a link for connecting the upper and lower locking devices cannot be embedded in the frame, the same problem as the glass door occurs. .

SUMMARY OF THE INVENTION The present invention solves such a problem by obtaining a door lifting / lowering locking device capable of simultaneously locking and unlocking a kanuki device installed on an upper edge and a lower edge of a door by a single operation. It is assumed that.

<Means for Solving the Problems> In order to operate the upper and lower locking devices simultaneously by one operation, the upper and lower locking devices must be connected by some means in order to interlock.

For example, when such a device is applied to a glass door, the connecting means is completely visually recognized from the outside, and the thickness of the glass door is naturally limited, so the connecting means is not a link made of a metal plate, etc. We decided to use a flexible wire made of metal or other material.

When a flexible wire is used to transmit the operation of one locking device to the other locking device, the operation on the initial side generates a traction force, and the component of the locking device on the secondary side is pulled by the force, and the locking is performed. The operation will be performed. In this case, operations such as pushing up and pushing by the link cannot be performed.

In order to operate the secondary locking device by traction, it is necessary to always bias the secondary locking device in the unlocking direction by a spring or the like. Thereby, the traction force of the flexible wire activates the secondary locking device against the action of the spring, and when the traction force is removed, the secondary locking device automatically returns to the unlocked position. Will be.

In addition, if a flexible wire is used as the connecting means, it is inevitable that the wire will be stretched with use. Therefore, the flexible wire is absorbed in the stretched state, and the flexible wire is always stretched in an optimum state. A stretch absorbing means is provided.

<Operation> According to the present invention, a locking device is installed at the upper and lower edges of the door, and they are connected by a flexible wire, and for example, the lower edge locking device is locked / unlocked by a key or a thumb turn. Thereby, the locking device on the upper edge side can be simultaneously locked and unlocked.

<Example> An example of the present invention will be described with reference to the drawings.

Reference numeral 43 denotes a connecting arm whose one end is pivotally connected to the sliding plate 34, and the other end is connected to a connecting rod 44 of the cam 27.

 The operation will be described.

To lock from the unlocked state shown in FIG. 1, first, the hub ball 10 of the casing 1 of the lower locking device is rotated counterclockwise in the figure.

As a result, the cam 11 presses the right protrusion 13 and slides the sliding plate 5 rightward in the drawing while drawing the flexible wire 9, so that the driving protrusion 16 presses the inner wall of the notch 4 and the lower cannula 2. Is rotated clockwise about the shaft 3 and its tip protrudes below the casing 1 to reach the state shown in FIG. As shown in FIG. 2, the distal end of the lower canker 2 is recessed in the seat H installed on the floor G, and the locking of the lower edge of the door D is completed.

In the above description, since the flexible wire 9 has been drawn downward in FIG. 1, the interlocking plate 28, the upper end of which is fixed, is moved to the left in the casing 17 of the upper locking device.

The leftward movement of the interlocking plate 28 against the action of the spring 31 causes the teeth 32 ′ of the adjustment rack 32 fixed to the right end of the interlocking plate 28.
The adjusting claw plate 39 provided with the adjusting claw 39 'meshed with is moved to the left, and at the same time, the sliding plate 34 on which the adjusting claw 39 is mounted is also started to move to the left. Along with the movement, the drive claw plate 41 also starts to move to the left, whereby the pressure contact between the pin 37 and its oblique side 42 is released, so that the drive claw plate 41 rotates clockwise about the shaft 38. The drive pawl 41 'meshes with the teeth 33' of the drive rack 33. The engagement between the claws of these two pawl plates and the teeth of the two racks is important for maintaining the mutual positional relationship between the interlocking plate 28 and the sliding plate 34 constant.

Due to the leftward movement of the sliding plate 34, the cam 27 of the hub ball 26 connected to the sliding plate 34 by the connecting arm 43 and the connecting rod 44 also swings counterclockwise, and the cam 27 Since the pressing plate 24 is moved to the left, the driving plate 24 also moves to the left, and at the same time, the driving projection 23 rotates the upper cannula 18 in the clockwise direction around the shaft 19 in the state shown in FIG. , The tip of the upper canker 18 falls into the seat H installed on the door frame F, and the locking of the upper edge of the door D is completed.

The unlocking is carried out by reversing the locking procedure from the state shown in FIG. 2, and by rotating the hub ball 10 clockwise, the sliding plate 5 is unlocked.
Moves to the left, and when the flexible wire 9 is extended, the interlocking plate 28 is moved.
Is slid to the right by the action of the spring 31,
Everything returns to the state of FIG. 1 and unlocking is completed.

Next, in the case where the flexible wire 9 has expanded with the lapse of the use time, in FIG. 1, the interlocking plate 28 is moved rightward by the action of the spring 31 by the action of the spring 31 in FIG. Will move. In this case, since the positions of all the components except the interlocking plate 28 are determined, the interlocking plate 28 moves rightward while changing the meshing position of the teeth 32 'of the adjustment rack 32 and the adjustment claws 39' of the adjustment claw plate 39. To stop at a new position while projecting its end to the outside of the casing 17. In the case of the present embodiment, the calculation is performed so that use of the flexible wire 9 is not hindered if the extension of the flexible wire 9 is within 20 mm.

Further, the case where the flexible wire 9 is cut will be described. Cutting in the unlocked state of FIG. 1 only causes the interlocking plate 28 to slide to the right, and FIG. If a stopper or the like is installed to keep the rightward sliding of the adjustment rack 32 within the range that can be supported, the hub ball 10 of the lower locking device can be manually operated until the repair is completed. Only the side can be unlocked.

When the flexible wire 9 is cut by the locking device of FIG. 2, the interlocking plate 28 slides to the right by the action of the spring 31, but the driving claw 41 'of the driving claw plate 41 and the driving rack Since the teeth 33 ′ of the 33 continue meshing until the sliding of the sliding plate 34 to the right is completed, the hub ball 26 connected to the sliding plate 34 by the connecting arm 43 also rotates, and the cam 27 In order to move the drive plate 21 rightward by pressing the right protrusion 25 of 21, the upper cannula 18 is rotated counterclockwise by the drive protrusion 23 and automatically returns to the unlocked state. Until the repair is completed, the lock is unlocked by the locking device below.

Although the description has been made mainly on the case where the present invention is applied to the glass door, it is apparent that the present invention can be mounted on any door and the mounting target is not limited.
