Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a closing lock device, a so-called fastener device, used for sash opening/closing windows, doors, etc. installed in openings of buildings.

<Prior Art> Rotating opening/closing windows and doors (hereinafter referred to as "doors" in this specification) provided at openings in buildings are equipped with the following measures for crime prevention or to prevent accidental opening due to wind pressure, etc. A fastener is used by the opening/closing handle.

A well-known type of fastener is typically one in which a latch integrally attached to a handle shaft engages and locks a strike provided at an opposing position on an opening frame.

FIG. 3 is a schematic external view of the door 1 to which the fastener 2 is attached. The fastener 2 is attached to the frame part 1 of the door 1.
A handle 3 protrudes from one side or both sides of the handle 3, and is attached to a rotating shaft (not shown) of the handle 3, and the protruding frame portion 1a is attached to a rotating shaft (not shown) of the handle 3.
Latch 4 that moves in and out in a circular motion from the side
And this latch 4 advances (rotatingly protruding from the frame part 1a)
It consists of a strike (not shown) provided on the opening frame side that engages with the opening frame. 1b is the rotation axis of the door 1.

<Problem to be solved by the invention> Generally, the fastener 2 is installed at one location on the door 1 with a relatively small opening, but in environments where the door 1 is subject to large wind pressure, etc. It becomes necessary to provide it not only at one location but also at multiple locations as necessary. In this case, it is conceivable to simply provide the required number of fasteners 2 integrated with the handle at appropriate intervals on the frame portion 1a. However, when a plurality of handles 3 protrude in this manner, it not only causes defects in the design of the door 1 but also complicates the operation, which is not a preferable method.

Therefore, multiple fasteners 2 are combined into one handle 3.
It has been proposed and proposed to operate the handle at the same time using an interlocking rod, but the mechanism for interlocking the operation of the handle becomes complicated, which poses problems in terms of reliability and durability, and also tends to increase costs. There was a need for improvement.

The present invention is provided to solve the above-mentioned conventional problems.

The object of the present invention is to obtain a highly practical fastener device that has an extremely simple configuration, has excellent operational reliability, excellent durability, and is inexpensive.

<Means for Solving the Problems> In order to achieve the above object, the fastener device of the present invention links multiple latches arranged on the door side opposite to the strike provided on the opening frame with a single handle. A fastener device equipped with an operation interlocking mechanism that is operated simultaneously by rods, one of the plurality of latches is provided so as to be rotatable in and out through an access opening formed in the interlocking rod, and a handle for operation is attached. At the same time, a locking pin is provided in the entrance/exit opening, a groove for locking the locking pin is formed in the latch to which the handle is attached, and when the handle is operated, the latch to which the handle is attached is inserted through the locking pin. The interlocking rod slides up and down.

<Operation> When all the latches are to be engaged with the strike from the unlocked state of the door, the handle is rotated in the locking direction. Then, the latch integrated with the handle rotates and projects in the direction of engagement with the strike. During this rotational protrusion, the latch, via the locking pin of the interlocking rod, causes the interlocking rod to slide linearly in one direction, for example upward. The other latches, except for the one integral with the handle, are operatively connected by interlocking rods, so that the above-mentioned upward slide will also actuate the other latches, and they will each protrude in the direction of engagement with the corresponding strike. . This causes the entire latch to engage the strike by operating the handle, locking the door in the closed state. To release the lock, perform the operation opposite to the above.

In this way, the groove formed in the latch that is integrated with the handle engages with the locking pin of the interlocking rod, and the interlocking rod is linked to the handle operation.
A fastener device can be obtained with a simple configuration.
In addition, by processing the latch that is integrated with the handle,
In addition to being used as a component of the above-mentioned operation interlocking mechanism in combination with other interlocking members, it can also be used as a single piece as a so-called one-point fastener similar to the conventional one, so productivity can be improved as a general-purpose product.

<Embodiments> Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

Figures 1 and 2 show an embodiment of the fastener device according to the present invention. Figure 1 is a sectional view of the main parts together with the operating state, and Figure 2 is a side view of the interlocking rod and the door frame. FIG.

In the figure, reference numeral 10 denotes an opening frame provided in an opening of a building, and strikes 11, 11a, 11b, etc. of fasteners are provided at appropriate locations on this opening frame.

Further, a door 12 is attached to the opening frame 10 so as to be rotatably openable and closable with one side as a rotation axis (not shown). In the frame portion 13 of the door 12, operating side members 14, 14a, 14b, . . . of fasteners are arranged at positions facing the strike 11. One of the plurality of operation side members 14 14a is composed of a handle 15 and a latch 16a integrally attached to a rotation support shaft 15a of this handle 15, and the others are only latches 16b, 16c, etc., which will be described later. It is configured as follows. These latches 16 rotate in and out from the frame portion 13 toward the corresponding strike 11 side by rotating the handle 15, and engage the strike 11 by rotating and protruding, thereby locking the door 12 in closing. do. Reference numerals 17, 17a, 17b, . . . are elongated grooves formed in the latch 16, which are engaged with a locking pin of an interlocking rod, which will be described later.

Reference numeral 18 denotes an elongated connecting plate that is slidable up and down along the strike surface side of the frame portion 13 of the door 12, and as shown in FIG. It is designed to be able to slide in such a way as to This connecting plate 18 has latches 16, 16a, 16b at the same intervals as the operation side member 14.
Access opening 1 with dimensions corresponding to the rotating protrusion diameter of...
9, 19a, 19b... are formed. In addition, the frame part 13 also has a latch 1 in the same way as the access opening 19.
Six entrance/exit openings 20, 20a, 20b, . . . are formed.

21, 21a, 21b... are front plates that fit into the access opening 19 of the connecting plate 18 and are fixed with screws, etc., and the latch 16 is provided on the surface corresponding to the access opening 19 in the same manner as described above. Access opening 2
2, 22a, 22b... are formed. and,
The latch 16 is attached to the groove 1 in the entrance/exit opening 22.
Locking pins 23, 23a, with a diameter that can be locked by 7.
23b... is provided. Then insert the latch 16 into the groove 17.
This locks the front plate 21 to the locking pin 23 of the front plate 21. The front plate 21 and the connecting plate 18 constitute an interlocking rod 24.

Note that the latches 16, 16 that do not have the handle 15
b, 16c... are attached so as to be interlocked with the vertical sliding movement of the connecting plate 18, and in the illustrated example, support shafts 25, 25a, 2 fixed to the frame part 13 are attached.
5b... and the locking pins 23, 23b, 23c... rotate around the support shaft 25, that is, rotate toward the strikes 11, 11b, 11c... to move in and out.

In such a configuration, the door 12 shown in FIG.
When unlocking the door 12 to open it from the closed and locked state, grasp the handle 15 and rotate it counterclockwise from the position shown in the figure. Then,
A latch 16 integrated with this handle 15
a rotates, but at this time the latch 16a is in the groove 17.
At the same time, the locking pin 23a that is locked at point a is pressed down. The locking pin 23a is connected to the interlocking rod 24
Since the locking pin 23 is integrated as a part of the locking pin 23, the load on the locking pin 23 acts as a load on the interlocking rod 24, causing the interlocking rod 24 to slide downward. The interlocking rod 24 slides linearly, and the locking pin 23a also moves linearly, which is different from the arc movement caused by the rotation of the latch 16a. Therefore,
If the locking position of the locking pin 23a and the latch 16a is a fixed point, the above operation will be difficult;
Since the groove 17a is formed in the groove 17a so that the locking position can be moved, the arcuate movement can be accurately converted into a linear movement (slide).

By sliding the interlocking rod 24 downward, the other latches 16b, 16c...
b, 23c... are latches 16b, 16 as active members.
c... acts and rotates counterclockwise in conjunction with the latch 16a. In this way, when the handle 15 is rotated approximately 90 degrees in the figure, each latch 16a, 16b... is rotated by the corresponding strike 11.
The state of engagement with a and 11b is released. That is, the lock is released and the door 12 can be opened. If the door 12 is to be closed and locked next time, the operation described above may be reversed.

In this way, by simply operating one handle 15, the latches provided at a plurality of locations can be operated simultaneously for corresponding strikes.

In the above embodiment, the latch 16a integrated with the handle 15 and the other latch 16b, 16c...
Although the shapes of the interlocking rods 24 are the same and the corresponding parts of the interlocking rods 24 are also the same, the invention is not necessarily limited to this.

That is, the groove 17a of the latch 16a may not only have a shape with one end open as shown in the figure, but may also have a so-called elongated hole shape. In addition, other latch 16b, 1
6c..., for example, attaches the latches 16b, 16c to the support shafts 25a, 25b...
A long hole is formed on the c... side, and it is slidably attached to the support shafts 25a, 25b.... The locking configuration of the locking pins 23b, 23c... and the grooves 17b, 17c... may be such that instead of the groove having an open end on one end, an elongated groove is used, or a circular hole for locking the pins 23b, 23c... is formed. It is conceivable to lock it.

In addition, as another embodiment, the other latches 16b, 16c, etc. in the above embodiment may be constructed so that they engage with the strike by moving linearly, whereas they engage with the strike by rotating motion. It will be done.

For example, the upper or lower end of the interlocking rod 24 may be used as a latch, and the upper or lower end portion may be used as the latch portion as it is, or a separate member may be attached to form the latch portion, and the corresponding portion may be used as the latch portion. A strike is disposed on the upper or lower frame of the opening frame, and is engaged with the strike by vertically sliding the interlocking rod.

In addition, when the lower end side of the interlocking rod 24 is used as a latch, the strike 1 of the latch 16 in the above embodiment is
There is no need to explain the fact that the direction of rotation for engagement and disengagement with 1 is opposite to that in the above embodiment.

It is also conceivable to use the configurations of each of the above-mentioned embodiments together as the other latch.

<Effects of the invention> As explained in detail above, according to the present invention, when multiple latches are interlocked, one latch and handle are integrated into an interlocking rod and pin locking, so that the configuration is simple. It is possible to obtain a fastener device that is simple. Furthermore, even if the latch integrated with the handle is grooved, it is not limited to a special member for interlocking operation, but can also be used as a handle member for a so-called single-point tightening fitting, so it can be used as a general-purpose product. production can be carried out.
In other words, it is also possible to save labor in design and production.
