[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drop rod device used to keep various doors such as gates and doors in a closed position.

[0002]

2. Description of the Related Art An example of this type of drop rod device is shown in Japanese Utility Model Laid-Open No. 59-15771. The device of the same publication has a plurality of through holes arranged in parallel in the vertical direction on the upper end side of the drop rod, and is provided with a locking claw that engages with the through hole and a button for releasing the engagement. It is designed so that it can be locked at the ascending position and the descending position.

In the above device, a lock device composed of locking claws and buttons and an operating portion for moving the drop bar up and down are separate bodies. There was also an integrated device that could be engaged on the side.

[0004]

However, in the above-mentioned conventional drop rod device, when the lock device and the operation portion of the drop rod are separate bodies, the operation becomes complicated and the operation is integrated. However, since it is necessary to push, pull, or rotate the operating unit to unlock the operating unit and then move the operating unit up and down, improvement in operability has been desired.

[0005]

OBJECT OF THE INVENTION The present invention aims to improve the operability of a drop rod device having a lock function.

[0006]

In the drop rod device according to the present invention, an operation member for moving up and down the drop rod is vertically movably fitted in a vertically long guide hole provided in a door body, and the operation is performed. On the back side of the member, an engaging member is provided which presses against both edges of the guide hole and the operating member by a biasing member, and the engaging member is inserted into the guide hole at the upper and lower portions of the guide hole. In the configuration, a notch that engages with each other is provided, and an inclined portion that is open vertically is provided on the back surface of the operation member that contacts the engaging member. The above configuration serves as means for solving the problem.

[0007]

In the drop rod device according to the present invention, the drop rod is locked in the raised position or the lowered position by engaging the engaging members with the notches provided in the upper and lower portions of the guide hole.

When the operating member is pushed upward or downward, the engaging member is pushed by the upper and lower inclined portions provided on the operating member, the engaging member is disengaged from the notch, and the locked state is released. By continuously moving the operating member upward or downward, the drop bar ascends or descends.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

The drop rod device in this embodiment is shown in FIGS.
As shown in FIG. 4, it is provided on the vertical bar B of the door body A for gates. As shown in FIG. 4, the horizontal bar B is a hollow body and has a mounting groove D whose bottom is the prospective wall C in the vertical direction. It is installed.

The drop rod device is provided with a vertically long guide hole 1 provided in the door A, and an operating member 3 for vertically moving the drop rod 2 so as to move up and down.

When the guide hole 1 is provided in the door A, as shown in FIG. 5, the cover plate 4 is an elongated frame-shaped outer side and the guide plate 5 is a strip-shaped inner side having the guide hole 1. Is used. These plates 4 and 5 are attached by aligning the edges of the opening from inside and outside according to the opening previously formed in the prospective wall C and screwing the overlapping portion. Further, on the upper and lower ends of the guide hole 1, a notch portion 1a for engaging an after-mentioned engaging member in the guide hole 1 in a protruding state,
1b is formed.

As shown in FIG. 2, the drop rod 2 of this embodiment is provided with a drop rod main body 6 projecting from the lower end of the vertical bar B and dropped into the receiving hole E, and a connecting rod 7. A support block 8 and a joint 9 are fixed to the upper and lower ends of the connecting rod 7, respectively. The drop bar main body 6 is guided vertically by a guide 10 screwed to the inside of the vertical bar of the prospective wall C, and the upper end is inserted into the insertion hole 9a of the joint 9, and the adjusting screw 11 is tightened to the same joint. The vertical position can be adjusted by loosening the adjusting screw 11.

The operation member 3 has an operation portion 3a having a shape easy to photograph on the front side, a projection 3b fitted into the guide hole 1 on the back side, and a front portion in the center. From the side to the back side, and a long hole 3c that is vertically long is formed. Further, on the back surface, inclined portions 3d and 3e are formed, which are inclined surfaces that open up and down around the long hole 3c. is there. The operation member 3 includes a pin 12 that is inserted into the long hole 3c.
Is connected to the support block 8 of the drop bar 2.

Further, the pin 12 is provided with a flanged ring-shaped engagement member 13 between the back side of the operation member 3 and the support block 8. The engagement member 13 is attached to the support block 8 by a coil spring 14 as a biasing member,
Both edge portions of the guide hole 1 and the vertically inclined portions 3d, 3 of the operation member 3
It is in a state of pressure contact with e, and chamfers are applied to the contact portions with the inclined portions 3d and 3e to make the operation even smoother.

In the drop rod device described above, the drop rod 2 is locked in the raised position or the lowered position by engaging the engaging member 13 with the upper or lower cutouts 1a and 1b of the guide hole 1. Even if the drop bar 2 is directly moved, the locked state is not released.

Next, when the operating member 3 is pushed upward in the locked state at the lowered position shown in FIG. 1, the engaging member 13 is pushed inward by the lower inclined portion 3e, and the coil spring 14 is pushed. The engaging member 13 is disengaged from the notch 1b while compressing, and the locked state is released. Then, as shown in FIG. 6, by continuously moving the operating member 3 upward, the drop bar 2 rises, and when the engaging member 13 engages with the upper cutout portion 1a, the locked state at the raised position is obtained. Becomes In addition,
While the operating member 3 is moving, the engaging member 13 in contact with the inclined portion 3e is displaced downward from the center of the operating member 3, but the escape is secured by the long hole 3c. further,
When moving the operating member 3 downward, the upper inclined portion 3
The engaging member 13 is pushed by d.

As described above, in the drop rod device, the drop rod 2 is moved up and down, locked at each position and unlocked by simply moving the operating member 3 up and down. Further, since the operating portion of the drop bar device is accommodated in the mounting groove D of the vertical bar B, the appearance is very good.

The drop rod device of the present invention is not limited to the above embodiment in specific structure, and may be provided on the door face of the door body, or the guide hole may be directly attached to the door body. It is also possible to form it, to further simplify the structure of the drop bar, to change the engaging member to an appropriate shape such as a substantially hemispherical shape, and to use rubber as the urging member.
Further, in the above-mentioned embodiment, the operating member and the drop rod are connected by the pin passing through the elongated hole of the operating member, and the engaging member is attached to the pin, but the drop rod is directly attached to the operating member. The operation member and the engaging member are fitted to the groove provided in the door body so that they can be moved only in the vertical direction, and the guide hole is engaged with each other. It is also possible to adopt a different configuration.

[0020]

As described above, the drop rod device of the present invention is capable of raising and lowering the drop rod and locking and releasing it at each position only by the vertical movement of the operating member. It is possible to obtain reliable operability.
