In this embodiment, the protruding members A and B which stand on the ground
This is a guard device that connects both ends of a bridge body C between them to define a place where entry is prohibited, etc., wherein a lock portion 1 is provided at one end of the bridge body C, while the lock portion 1 is inserted into a protruding body A. And an opening 3 having a locked portion 2 formed around the opening 3, and a part of the opening 3 concealed from the inside by a resilient mechanism 5 in a gap 4 of the protruding body A communicating with the opening 3. And an actuating body 7 concealing a part of the opening 3 and an unlocking / preventing portion 8 for preventing the locking / unlocking of the locking portion 1 locked to the locked portion 2. is there.

The projecting bodies A and B are stored underground when unnecessary.
15 is a pole body that is housed and buried in the housing 15 and pulled out of the housing body 15 during use and is erected and held on the ground.
The coupling mechanism of this embodiment is provided above B.

A projecting body C connected to another projecting body B is connected to the projecting body A via a retaining body 13, and this projecting body C is stored in a storage section 12 in the projecting body A when unnecessary. Is done.

A chain C is employed for the erection body C so that it is difficult for an unlawful person to cut the erection body easily. The retaining member 13 is provided at the base end of the erection body C. An engaging portion 1 is provided. Reference numeral 14 denotes a projecting member that allows the erection body C to be pulled out of the storage part 12 when the erection body C is stored in the storage part 12.

The locking portion 1 is constructed by providing a flange 9 at the end of a base 10 in a protruding state.

The opening 3 is formed by connecting a large-diameter hole 3a and a vertically-elongated small-diameter small hole 3b in a continuous manner. The large-diameter hole 3a is set in a shape through which the locking portion 1 can pass. The small-diameter hole 3b is set in a shape that allows the base 10 of the locking portion 1 to pass therethrough and does not allow the flange portion 9 of the locking portion 1 to pass through.

The thickness of the inner wall 6 around the opening 3 (especially the small hole 3b) is set to be thinner than the front and rear length of the base 10 of the locking portion 1. Therefore, the locked portion 2 is provided below the small diameter hole 3b so that the flange portion 9 of the locking portion 1 is hooked and locked.

A protrusion 5 is provided in the gap 4 of the protruding body A communicating with the opening 3 as a resilient pressure mechanism 5. The protrusion 5 is pressed against the inner wall 6 around the opening 3 by the resilient pressure of the protrusion 5.

In addition, even when the opening 3 is concealed by the operating body 7, the small-diameter hole 3 b of the opening 3 is configured to be opened by the cross-sectional shape of the base 10 of the locking portion 1. When the locking portion 1 is locked at the end, the end of the operating body 7 is located above the locking portion 1, and the end of the operating body 7 restricts the upward movement of the locking portion 1 and The locking / unlocking prevention unit 8 prevents the locking unit 1 locked by the locking unit 2 from unlocking. When the operating body 7 is pressed with a rod or the like to move the locking / unlocking prevention portion 8 (the end of the operating body 7) from the upper portion of the locking portion 1 locked to the locked portion 2 to another location. It is possible to release the locking between the locking portion 1 and the locked portion 2, and to pull out the locking portion 1 from the opening 3 to release the connection between the projecting body A and the bridge C. Becomes

In this embodiment, since the size of the large-diameter hole 3a of the opening 3 is substantially the same as the size of the flange 9 of the locking portion 1, a rod or the like is inserted through the opening 3. When the actuating body 7 is pressed, the pulling out of the locking portion 1 may be hindered by the rod (that is, even if the opening 3 is pressed with a finger or the like, the locking portion 1 does not pull out, and the protrusion A is bridged. The method of releasing the connection with the body C is more difficult to understand.) Therefore,
In this embodiment, an operation hole 11 is provided above the vicinity of the opening 3 so as to push the operating body 7 by inserting a rod or the like, so that the locking portion 1 can be pulled out of the opening 3 smoothly. . If the operation hole 11 is formed into a complicated shape such as a curved or bent shape and the operating body 7 cannot be operated unless a rod having a longitudinal section corresponding to the shape is used, the protruding body A It is much more difficult to release the connection between the operating body 7 and the erection body C. However, since the rod or the like for operating the operating body 7 has to be separately managed, the operation effect is advantageous and disadvantageous.

The method of use of this embodiment will be described in detail (see FIGS. 3 and 4).

The operation for disposing the bridge C between the protrusions A and B will be described below.

The projecting bodies A and B buried in the ground are stored
15 and is held upright.
Is pulled out from the storage portion 12, and the locking portion 1 of the built-in body C comes into contact with the operating body 7 concealing the large-diameter hole 3a of the opening 3 of the adjacent protruding body A. .

Subsequently, the operating body 7 is pressed against the elastic force of the struts 5 by the locking portion 1, and the locking portion 1 is pressed between the operating body 7 and the inner wall 6 around the opening 3 of the protruding body A. Is moved from the large-diameter hole 3a to the small-diameter hole 3b.

Subsequently, when the locking portion 1 is moved downward to the locked portion 2 (the position where the locking portion 1 does not press the operating body 7) below the small diameter hole 3b, the operating body 7 is moved to the starting position. Is pressed against the inner wall 6 around the opening 3 of the protruding body A again by the resilient pressure, and the lock release preventing portion 8 at the end of the operating body 7 is engaged to lock the locking portion 1. To prevent the locking portion 1 from coming out of the opening 3 (large-diameter hole 3a).

The operation for releasing the connection between the projecting bodies A and B and the bridge C will be described below.

An appropriate rod is inserted from the operation hole 11 of the protruding body A, and the operating body 7 is pressed by the rod against the elastic force of the struts 5 to prevent the locking and disengaging of the operating body 7. Is released (the contact between the actuating body 7 and the inner wall 6 around the opening 3 is released to release the locking action of the locking / release preventing portion 8).

Subsequently, while the operating body 7 is being pressed by the rod,
The locking portion 1 is fixed to the operating body 7 and the inner wall 6 around the opening 3 of the protruding body A.
Is moved from the small-diameter hole 3b to the large-diameter hole 3a along the gap, and the locking portion 1 is pulled out from the large-diameter hole 3a, and the rod is also pulled out from the operation hole 11.

Since the present embodiment is constructed as described above, the projecting body A and the bridge C are inserted by a simple operation of inserting the locking portion 1 of the bridge C through the opening 3 of the protrusion A and moving it downward. The connection can be released by a simple but unprecedented special operation of moving the locking portion 1 upward while pressing the operating body 7. The guard device is excellent in practicality and cannot be easily disconnected from the erection body C.

The opening 3 is formed with a large-diameter hole 3a and a small-diameter hole 3b.
The large-diameter hole 3a is set to a shape that allows the flange 9 of the locking portion 1 to pass therethrough, and the small-diameter hole 3b is formed so that the base 10 of the locking portion 1 can pass therethrough and locked. Since the flange portion 9 of the portion 1 is set to a shape that cannot pass, the locking portion 1 of the construction body C has a small diameter by inserting the locking portion 1 into the large-diameter hole 3a and moving it toward the small-diameter hole 3b. It is locked by the locked portion 2 of the hole 3b to be in a retaining state, and the bridge C can be connected to the protruding body A with a simple structure such as providing a flange 9 at the locking portion 1 of the bridge C. This is a guard device with excellent practicality.

Further, since the base end of the bridge C is irremovably connected to the other protrusion B via the stopper 13, the connecting operation between the bridge C and the protrusion is performed by the bridge. Only the work of connecting the tip of C is sufficient.
If the erection body C is stored in 12, the erection body C can be buried and stored in the underground storage body 15 together with the erection body, and it is excellent in practicality and workability such that a storage space is not required. It becomes a guard device.
