And a locking groove 22 that extends vertically downward from the lower end as well. The lengths of the locking grooves 22, 31 are all equal. Note that the locking rod 29 is movable along the guide groove 21 and the locking grooves 22, 31.

In particular, as shown in FIGS.
Each of the base ends is attached to each of the support shafts 28 of the fixing member 16 so as to be rotatable in the vertical direction. Since these support members 23 have exactly the same shape as each other, the configuration of only one of the support members 23 will be described below.
That is, as shown in FIG. 4 (a), at the base end of the support member 23, a locking hole 25 extending in the length direction thereof,
A circular shaft hole 24 located on the distal end side from 25 is provided, and each support shaft of the fixing member 16 is provided in the shaft hole 24.
26 is inserted, and the locking rod 29 is inserted into the locking hole 25. Therefore, the locking rod 29 can slightly move in the length direction of the support member 23.

The bearing shaft 28 is inserted into the shaft hole 24 and the bearing hole 20 of the fixing member 16.
, The locking holes 25 of the support member 23 correspond to the guide grooves 21 and the locking grooves 22 and 31, respectively.
The length of the locking hole 25 is equal to or slightly longer than the locking grooves 22, 31.

As shown in FIG. 3, the support member 23 has a cylindrical shape, and both ends are closed by caps 37 and 41, respectively. An insertion hole 38 is provided at the center of each cap 37 on the tip side.

An operating body 49 is inserted into each bearing member 23 so as to extend over the entire length thereof. This operation body 49 is
The support member 23 is slightly movable in its length direction. Further, it comprises a plate-shaped connecting member 32 located on the base end side of the support member 23, and an operating body 35 fixed to the distal end thereof.

As shown in FIG. 4 (b), a circular rod hole 33 is provided at the base end of the connecting member 32, and an elongated hole 34 located at the distal end side thereof.
Are provided respectively. The support shaft 28 of the fixing member 16 is inserted into the elongated hole 34, and the locking rod 29 of the fixing member 16 is inserted into the rod hole 33. The proximal end of the operation body 49 is supported by the support shaft 28. The locking rod 29 is slightly movable in the length direction of the support member 23.

When the support shaft 28 corresponds to the distal end (the left end in FIG. 4 (b)) of the elongated hole 34 of the connecting member 32 and the bearing hole 20 of the fixing member 16, the rod hole 33 and its locking rod 29 Lock groove 22, 31
Corresponding to When the support shaft 28 is located at the base end of the elongated hole 34, the rod hole 33 and its locking rod 29 can correspond to the guide groove 21.

The tip of the operation body 35 projects outside the support member 23 through the insertion hole 38 of the cap 37. A knob 40 is attached to the tip of the operation rod 35. A slight gap is formed between the knob 40 and the cap 37.

An elastic member 36 is mounted on the operation rod 35 in the support member 23. Both ends of this elastic member 36 are connected
The tip of 32 and the cap 37 are in contact with each other. Therefore, the operating body 49 is constantly urged toward the back plate 17 by the elastic member 36. In this biased state, the support shaft 28 is located at the base end of the elongated hole 3, and the locking rod 29 is at the back of the locking groove 22 or 31. Therefore, the support member 23 cannot rotate in the vertical direction.

As shown in FIG. 1, a cloth frame 39 (shown in FIG. 6) for preventing slippage is provided upright at the front end of the support member 23.
A protruding piece for hooking the cloth frame 30 is located at the base end
27 are installed.

The gap bracket 10 configured as described above is attached to the scaffold 1
In order to mount the support frame 23, the pillar 2 of the framework scaffold 1 is fitted into the opening insertion portion 15 of the mounting member 11 such that the end of the support member 23 faces obliquely upward. Then, when the entire support member 23 is returned so as to be in a horizontal state, the vertical fitting portion 12 of the mounting member 11 is returned.
And the vertical engaging portion 13 are fitted so as to embrace the pillar 2 respectively. When the gap bracket 10 is lowered in this state, the horizontal fitting portion 14 is fitted and locked on the upper surface of the cross beam 3.

When the gap bracket 10 is engaged with the framework scaffold 1 in this manner, the gap bracket 10 does not fall out of the mounting position and does not drop laterally around the pillar 2. Furthermore, the gap bracket 10 is
Even when a downward load is applied to 23, it can be sufficiently supported by the support 50, and is mounted on the framework scaffold 1 in a stable state.

After the above operation is repeated and the gap brackets 10 are sequentially mounted on the frame scaffold 1, the cloth frame 30 for preventing falling objects or falls is mounted on the support member 23 as shown in FIG. This cloth frame 30
Is a support fitting (not shown) which is a pair of two protruding pieces 2 of the support member 23.
By being inserted between 6, 27, it does not slip off from the bearing member 23.

During the use of the gap bracket 10 on which the cloth frame 30 is mounted, if it becomes necessary to temporarily remove the cloth frame 30 and lift and lower the material from the gap between the building, As shown in FIG. 5, the knob 40 of the operation rod 35 protruding outside the support member 23 is pulled toward the distal end of the support member 23 against the elasticity of the elastic member 36. Then, the connecting member 32 moves together with the operation rod 35. Then, the operating rod 29 communicated with the rod hole 33 of the connecting member 32 moves from the back of the locking groove 31 to the upper end of the guide groove 21.
At this time, the support shaft is attached to the base end of the elongated hole 34 of the connecting member 32.
28 will be located.

As a result, the locked state of the support member 23 is released, so that the distal end of the support member 23 can rotate upward. In this state, when the tip of the support member 23 is rotated upward with the support shaft 28 as a fulcrum, the locking rod 29 is guided by the guide groove 21 and moves downward. Then, as shown in FIG.
If the locking rod 29 corresponds to the lower end of the guide groove 21 when the support member 23 is in the vertical state, the locking rod 29 is automatically moved to the locking groove 22 by the urging force of the elastic member 36 in the support member 23. The support member 23 is locked in this vertical state. At this time, the operating body 49 of the support member 23 is slightly lowered with respect to the support member 23 by the urging force of the elastic member 36.

Accordingly, the cloth frame 30 mounted on the support member 23 rotates together with the support member 23, and is supported by the protrusions 27 for retaining the cloth frame 30 of the support member 23, and is held in a vertical state. A state is created in which a gap is formed between the object and the object.

To return the cloth frame 30 and the support member 23 to the horizontal state, the same operation as described above may be performed.

Further, in this embodiment, the locking rod 29 moves extremely easily only by pulling the operating rod 35 protruding outside the support member 23 toward the distal end of the support member 23, and the locked state of the support member 23. Can be canceled.

As a result, the support member 23 can be easily operated in the horizontal state and the vertical state, and the cloth frame 30 can be temporarily removed.

Further, the provision of the locking grooves 22 and 31 in the fixing member 16 allows the support member 23 to be reliably locked in the horizontal state or the vertical state by the locking rod 29.

Since the connecting member 32 and the locking rod 29 are constantly biased toward the base end of the support member 23 by the elastic member 36, the locking rod
29 does not easily move from the locking grooves 22 and 31 to the guide groove 21 due to an external impact or the like.

Furthermore, when the support member 23 is in the horizontal state or the vertical state, when the locking rod 29 reaches the upper end or the lower end of the guide groove 21, the locking rod 29 is automatically and automatically biased by the urging force of the elastic member 36,
It is possible to securely fit into the locking grooves 22, 31.

Since the gap bracket 10 of this embodiment is composed of the mounting member 11, the fixing member 16, and the support member 23, the number of constituent members is small, the structure is extremely simple, and the gap is formed by setting the support member 23 to a vertical state. Can be made,
The work of removing and attaching the cloth frame 30 becomes unnecessary.

Note that the present invention is not limited to the above-described embodiment, and can be arbitrarily changed without departing from the spirit of the present invention.

For example, as shown in FIG. 7, a mounting bracket 42 may be fixed to the back plate 17 instead of the mounting bracket 11. This mounting bracket 42
The use of the bracket makes it possible to attach the gap bracket 10 to any position on the pillar 2 of the framework scaffold 1.

Next, a second embodiment of the present invention will be described with reference to FIGS.

The difference between this gap bracket 10 and the configuration of the gap bracket 10 of the first embodiment is that, as shown in FIG. 8, the diameter of the support shaft 28 supporting the support member 23 is increased and the length is increased. This is the point that the protrusions 26 and 27 at the tip of the support member 23 are omitted.

In this embodiment, as shown in FIGS.
A support fitting 43, a hook 44, and a claw member 45 are respectively attached to both sides in the length direction of. The support fitting 43 is formed in a horizontal U-shape, the inside of which is a support groove 46 into which the tip of the support shaft 28 is inserted, and the bent portion serves as a support portion 43a that can be engaged with the support member 28. I have. And the opening 46a of the bearing groove 46
Faces the base end direction of the support member 23. The cloth frame 30 is movable in the length direction of the support member 23 by the support groove 46. Further, the bearing 43 is rotatable by the support shaft 28.

The hook 44 is fixed to the cloth frame 30 so that the concave portion 47 faces downward. The tip of the support member 23 is fitted into the recess 47 from below, and the hook 44 is movable in the length direction of the support member 23.

The claw member 45 is formed in an L-shape in a plane, and an engagement groove 48 that opens downward is provided at a tip portion 45a. Same engagement groove 48
An operation rod 35 at the tip of the support member 23 is fitted into the arm member 45. The tip 45a of the claw member 45 can be engaged with the knob 40 at the tip of the operation rod 35.

When the cloth frame 30 constructed as described above is mounted on the gap bracket 10, as shown in FIG.
The tip of the support shaft 28 is fitted into 46, the support member 23 is fitted into the concave portion 47 of the hook 44, and the operating rod 35 is fitted into the engaging groove 48 of the claw member 45.

Thus, the gap bracket on which the cloth frame 30 is mounted
If it is necessary to make a gap between the building and the building during use, place a hand on the substantially central part (not shown) of the fabric frame 30 in the length direction, and as shown in FIG. The frame 30 is moved toward the distal end of the support member 23. At this time, the support fitting 43 slides on the support shaft 28 in the length direction of the support member 23, and the hook 44 also slides on the support member 23 in the same direction. Therefore, the distal end portion 45a of the claw member 45 engages with the knob 40 at the distal end of the operation rod 35, and the operation rod 3
5 also moves toward the tip of the support member 23. Therefore, similarly to the first embodiment, the locking rod 29 of the fixing member 16 moves from the locking groove 31 to the upper end of the guide groove 21. Therefore, the support member 23 can rotate upward.

In this state, as shown in FIG. 11, when the cloth frame 30 is rotated in the upward direction, the locking rod 29 is locked by the urging force of the elastic member 36 when the support member 23 is in the vertical state. Fit into 22. At this time, the operating body 49 is slightly lowered in the base direction of the support member 23, and the cloth frame 30 is also slightly lowered in the same direction. The support portion 43a of the support bracket 43 is supported by the tip of the support shaft 28 so that the cloth frame 30 does not fall downward.

When returning the cloth frame 30 to the horizontal state, the worker puts his hand on the center of the cloth frame 30 in the longitudinal direction and lifts the cloth frame 30 upward. Then, since the locking rod 29 moves from the locking groove 22 to the lower end of the guide groove 21, the horizontal state can be returned.

When setting the cloth frame 30 in the horizontal state and the vertical state,
By moving the support member 30 in the length direction, the support members 23 on both sides of the cloth frame 30 can be operated at the same time. Therefore, there is no need to operate the support members 23 on both sides of the cloth frame 30, and the work of setting the cloth frame 30 to the vertical state and the horizontal state can be performed very easily by one person.

[Effects of the Invention] As described in detail above, the gap bracket according to the first invention of the present application is composed of the mounting member, the fixing member, and the support member, so that the number of constituent members is small and the structure is extremely simple. Can be reliably locked in a horizontal state.

In the second aspect, the locking rod can be moved by operating the operating body outside the support member, so that the locking rod does not need to be directly operated. As a result, the rotation operation of the support member is easy.

Furthermore, in the third aspect, since the elastic member constantly urges the locking rod toward the base end of the support member, the locking rod can be automatically and reliably inserted into the locking groove. it can.
Therefore, the support member can be reliably locked in a horizontal state.

In the fourth aspect, since the claw material attached to the cloth frame is engaged with the operating body of the support member, the claw material is operated through the operating body in the length direction of the cloth frame and the supporting member, so that the operation member is locked. Since the rod can be moved, even the rotation operation of the cloth frame can be performed very easily by one person.
