Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention mainly relates to a connecting and pulling mechanism for connecting and pulling movable members such as shutters and doors of buildings.

(Prior Art) Conventionally, a wooden house has a door pocket of a specified size, and a plurality of individual doors are joined in a horizontal row by sliding rails (or guide grooves). The shutters that are formed by arranging are used.

(Problems to be solved by the invention) However, since there may be a gap between the doors when the shutter is closed, some means for bringing the doors into close contact with each other is desired. When opening again,
Stand at the door pocket of the door pocket and store them one by one, but when you store the door located at the end opposite to the door pocket side of this rain door, it will be repeated to that position many times. Since it is troublesome to go to pick up the doors, it is conceivable that the doors can be stored more easily if the individual doors are connected. However, at present, no mechanism for connecting the individual shutter doors has been devised as described above.

Therefore, the present invention solves the above-mentioned conventional problems,
Mainly to provide not only individual doors of shutters but also movable members that can move easily, and to provide a compact connected traction mechanism with a simple structure that can be towed, and to expand the range of use of movable members for buildings. It is an issue.

(Means for Solving the Problem) The gist of the present invention is, however, a connecting and pulling mechanism including a first connecting portion and a second connecting portion, wherein the first connecting portion is a movable member. A hook member that has a hooking portion that is fixed and that can be hooked and that is swingably mounted with the other end as a fulcrum, and that has a convex portion and an unlocking means at the center. It has an end portion projecting from a movable member that is biased by the biasing means and is attached, and this end portion fits the convex portion of the hook member at a predetermined position returned against the biasing force of the biasing means. And a lock rod having a locking hole, and the second connecting portion is provided on a movable member adjacent to the movable member, and an opening for inserting and locking the locking portion is formed, and It has a surface with which the end of the lock bar abuts.

(Operation) Therefore, when the movable members are connected to each other, the movable members are connected to each other only by lightly pressing one movable member against the adjacent movable member. That is, the hook portion at the tip of the hook member of the first connecting portion is inserted into the second connecting portion, and the end portion of the lock rod abuts on the contact surface of the second connecting portion so that the lock rod is inserted into the first connecting portion. When pushed in, the convex portion of the hook member fits into the locking hole of the lock rod at this position, the hook member moves downward, is locked by the second connecting portion, and the hook member is locked by the lock rod. Thus, the movable members are connected to each other. In addition, when the connection between the movable members is released, the hook releasing member is manually operated to move the hook member upward, thereby removing the convex portion of the hook member from the hook hole,
The hooking portion of the first connecting portion and the second connecting portion are released to separate the movable members from each other, and the hook member and the lock rod are released because the lock rod is projected by the biasing means. Is something that can be done.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1 and FIG. 2, the connecting and pulling mechanism 1 is the first
It is composed of a first box case 2 that serves as a connecting portion and a second box case 3 that serves as a second connecting portion that is in close contact with the first box case 2. The first box case 2 and the second box case 3 are formed of a shock-resistant material such as metal or synthetic resin.

An elongated plate-shaped hook bar 4 is horizontally arranged in the first box case 2, and its rear part is pivotally supported by a pin 5, and the hook bar 4 is swingably provided with the pin 5 as a fulcrum. There is. A hooking portion 6 is formed at the tip of the hook bar 4 so as to project from the window 7 to the outside of the case so that it can be hooked with the second box case 3. A leaf spring 8 for accelerating gravity is arranged on the upper side of the hook bar 4 to push the hook bar 4 downward. Further, the hook bar 4 is provided with a releasing piece 9 which serves as a hook releasing means in the middle and a convex portion 10 which projects downward. The release piece 9 projects from a slit 11 formed on the upper surface of the first box case 2. The lock bar 12 is in the first box case 2,
It is arranged in the horizontal direction and is regulated by the guide plate 14, and its tip projects from the window 13 formed in the first box case 2,
The other end is in contact with the other end of the spring 15 whose one end is fitted and fixed to the convex portion 2b provided in the first box case 2.

Therefore, the lock rod 12 is urged by the spring 15 so that its tip projects from the window 13. A hook hole 16 is formed on the hook bar 4 side of the lock bar 12,
In the state as shown in the figure, the convex portion 10 is on the lock rod 12 and is not fitted in the hook hole 16.

Further, the second box case 3 serving as the second connecting portion has a hooking window 17 formed on the side facing the first box case 2, and the hooking portion 6 of the hook rod 4 is formed in the hooking window 17. It is inserted and hooked.

Both the first and second box cases 2 and 3 are formed with screw holes 18 for mounting on the door.

The operation of the connection / traction mechanism having the above configuration will be described. Third
As shown in FIG. 4 and FIG. 4, the connection and traction mechanism is used by fixing the first box case 2 and the second box case 3 to the substantially central portion on the inner side of the joint side of each shutter with, for example, wood screws 19 or the like. To do. When closing this shutter, slide each door on the rail (or guide groove) and, for example, push the door 26 adjacent to one door 25 and lightly hit it.
25 and 26 are closely connected. At this time, the first
At the same time that the hooking portion 6 of the box case 2 is inserted into the hooking window 17 of the second box case 3, the tip of the lock bar 12 is pushed by the facing surface 3a of the second box case 3 to guide the plate.
While being guided by 14, the lock bar 12 is pushed in until the tip of the lock bar 12 is flush with the surface 2a of the first box case 2, and the spring 15 is compressed. At this time, the hook bar 4 is pushed by the elastic force of the leaf spring 8 and the convex portion 10 thereof is fitted into the hook hole 16.

As a result, the hook bar 4 rotates about the pin 5 as a fulcrum in the direction of arrow A by a predetermined angle, and as shown in FIG.
Is hooked (hooked) inside the hooking window 17 of the second box case 3, and the first box case 2 and the second box case 3 are connected to each other with their opposing surfaces 2a and 3a joined. That is, the two shutters are connected in close contact with each other without a gap.

On the other hand, when opening the shutter, as shown in FIG.
First, in order to separate the door closest to the door bag 27 and the door connected thereto, as shown in FIG. 3, the release piece 9 is manually moved in the direction of the arrow B so that the second box case 3 is locked. At the same time that the latching part 6 that is locked is released
The convex portion 10 of the hook bar 4 that has been fitted into the 12 hook holes 16 also comes out of the hook holes 16.

As a result, the lock bar 12 is pushed out in the direction of arrow C by the elastic force of the spring 15, and at the same time the second box case 3
Will press the opposite surface 3a. By this reaction, the first box case 2 is separated from the second box case 3, and the adjacent doors 25 and 26 are separated. Next, the separated door is stored in the door bag 27. Then, when the extended door 25 is pulled toward the front (in the direction of arrow D) by extending the hand, all the other doors are connected, so that the entire connected door is drawn.

After that, the doors are disconnected from each other in the same manner as described above, and the doors are housed one by one in the door pocket 27. in this way,
When opening the shutter, you can easily perform the work in three steps: standing by the door bag 27 to release the release piece 9, storing the shutter in the door bag 27, and pulling the remaining shutters toward you. .

In the embodiment, the method of moving the releasing piece 9 provided on the hook rod 4 as the hook releasing means is shown. However, as shown in FIG. It is also possible to use a method in which a release rod 9a (indicated by a chain line) connected to 4 (the connected portion is not shown) is provided and the release rod 9a is released by pushing.

In addition, in this embodiment, the first connecting portion and the second connecting portion are provided separately from the door, but as shown in FIG. 5, the first box case 2 and the second box case 3 are provided. , The window 7 is formed in the door 26, and the hanging window 17 is formed in the door 25.

Is also good. Further, it can be used for connecting and disconnecting the accordion curtain of the upper edge hanging type and the pile.

(Effects of the Invention) As described above, according to the present invention, since the connecting and pulling mechanism for connecting the movable members such as the doors is attached to each movable member, the adjacent movable member is pushed by one movable member. Anyone can easily connect them in close contact with each other by lightly hitting them, and it is robust and safe against strong winds and strong earthquakes.
And the connected door cannot be separated from the outside. For example, if you use it for a sliding door that is a movable member, you can pull the entire sliding door while standing in a fixed position near the door pocket when opening, so you do not have to go to the door as often as before, and you can easily store the door with a small amount of labor. It can be performed.

In addition, the inconvenience that it is difficult to install a rain door without a wall of three or more shaku on the outside of the building in accordance with the standard size of the door of the rain door can be solved by the equipment of the connecting and pulling mechanism by the general use of movable building members.

Since the connection / traction mechanism has a compact structure,
The attachment can be easily performed regardless of the structure of the movable member to be attached. Further, if the material is properly selected, the structure is simple, so that it is easy to mass-produce.
