Description

  The present invention relates to a temporary enclosure for an elevator that is temporarily installed in an elevator hall only for a predetermined period, such as when an elevator is repaired.

  At the time of repair work at the elevator hall, a temporary enclosure is installed at the elevator hall for a predetermined period. This temporary enclosure has a role of forming a work space for elevator repair workers and ensuring the safety of passers-by.

Conventionally, each time an elevator repair work is performed, a temporary enclosure is appropriately installed using a wooden frame, a gypsum board, or the like, and dismantled at the end of the work period.
Patent Document 1 adopting a bellows type and Patent Document 2 in which a side wall and a ceiling are each foldable by using a movable panel have been proposed as being capable of appropriately changing the depth of the temporary enclosure of the elevator hall. .

The conventional temporary enclosure can be changed in depth, but cannot be moved easily.
In particular, when a gypsum board or an iron plate is used as the temporary enclosure, the temporary enclosure itself becomes very heavy (for example, about 200 kg), and it is extremely difficult to move it by simply dragging it.
If you try to move it forcibly, you may damage the floor where it is installed, and even if you prepare and move the dolly, you can not move the dolly without lifting the temporary enclosure and move. There was a problem that was extremely difficult.
For this reason, when the work is continuously performed where a plurality of elevators are arranged, it is very troublesome to move the temporary enclosure to the next elevator, and there is a problem that many work processes are required.
Similarly, when removing the three-way frame set in the elevator and performing construction, when using equipment such as a tearing drill to crush the surrounding concrete, work cannot be performed in the temporary enclosure. There is a case where it is desired to temporarily move the enclosure from the wall surface, but there has been a problem that the conventional temporary enclosure cannot be easily moved as described above.
Similarly, when moving to the next site after the work is completed, the process of disassembling and assembling one by one is conventionally required, and the temporary enclosure itself cannot be easily moved.

The main body of the elevator temporary enclosure 1 is formed in a box shape by combining iron plates and the like, and the surface attached to the elevator is open. The number of iron plates constituting the elevator temporary enclosure 1 can be combined with any number according to the site, and an elevator temporary enclosure of any size can be created.
A door for an operator to enter and exit the temporary enclosure is provided in front of the elevator temporary enclosure 1.
Moreover, in this embodiment, the caster 2 is attached to each of the left and right sides of the front surface in the width direction on both sides, and one on each side of the elevator temporary enclosure 1 in the width direction and slightly closer to the elevator. . As a result, a total of four casters 2 are attached. The position and the number of the casters 2 attached are arbitrary.

  As shown in FIG. 3, the caster 2 includes a fixed bracket 21 for detachably attaching the caster 2 to the elevator temporary enclosure 1, a movable bracket 22 that is rotatably attached to the fixed bracket 21, A locking (regulation) bracket 23 that locks and restricts the movable bracket 2, a rotation stopping bracket 24 for restricting rotation, a front bracket 25 that exposes a release lever of the locking bracket 23, and shafts 26 and 27. , 28 and caster wheels 29 attached to the bottom surface of the movable bracket 22.

The fixing bracket 21 has a back plate 210 and side plates 211 and 211.
The back plate 211 connects the side plates 211 and 211, and a hole is formed in the upper end portion thereof, and the rotation stop bracket 24 is attached to the hole with a screw or the like.
The side plate 211 has an upper engagement piece 211a and a lower engagement piece 211b to be attached to the temporary enclosure 1 on the back side. The casters 2 are attached to the temporary enclosure 1 by the engagement pieces 211a and 211b being inserted into and engaged with the insertion slits 11 provided on the temporary enclosure 1 side. Thus, only when the movement is necessary, the engagement pieces 211a and 211b are inserted into the insertion slit 11 of the temporary enclosure 1 and moved using the casters 2, and then the engagement is completed when the movement is completed. By removing the pieces 211a and 211b from the insertion slit 11, the caster 2 can be attached to the temporary enclosure 1 only when necessary.
In the upper front side of the side plate 211, a hole 212 is formed through which the shafts 26 and 27 that are the center when the movable bracket 22 rotates are inserted.
In addition, a long hole 213 for restricting the rotation range of the movable bracket 22 is formed in the lower portion of the side plate 211. The long hole 213 is formed in an arc shape according to a trajectory in which the movable bracket 22 rotates about the shafts 26 and 27.
Further, a hole 214 through which the shaft of the locking bracket 23 is inserted is formed in the lower back side of the side plate 211.

The movable bracket 22 includes a bottom plate 211 and side plates 222 and 222 formed so as to rise integrally from both ends of the bottom plate 211.
The width of the movable bracket 22 is smaller than the inner width of the fixed bracket 21, so that the movable bracket 22 can be rotated in the fixed bracket 21.
A hole for attaching the caster wheel 29 is formed in the bottom plate 211, and the caster wheel 29 is attached to the hole by a bolt and a nut.
In the side plate 222, a slit 223 for engaging with the engaging piece of the front bracket 25 is formed at the upper center.
A hole 224 through which the shafts 26 and 27 that become the center when the movable bracket 22 rotates is formed in a portion closer to the front surface than the slit 223 of the side plate 222.
In addition, a hole 225 for inserting the shaft 26 is formed in the lower part of the side plate 222 and a part slightly behind.

The locking bracket 23 is formed in a planar convex shape having a lever portion 231 protruding forward.
The lever portion 231 has a length protruding from the hole 251 of the front bracket in a moving state by a caster.
The locking bracket 23 has side walls extending downward at both ends thereof.
Holes are respectively provided in the back side (fixed bracket 21 side) of the side walls at both ends, and a shaft (not shown) is inserted into the holes and holes 214 and 214 of the fixed bracket 21 so that the shaft is the center. The locking bracket 23 can be rotated with the movement of the movable racket 22.
An inclined surface 233 and an engagement hole 232 communicating with the inclined surface 233 are formed on the front side of the side wall (on the movable bracket 22 side). This engagement hole 232 is for engaging with the shaft 28 and restricting the movement of the movable bracket 22 in a state in which the movable bracket 22 is moved by a caster, that is, in a state where the movable bracket 22 is located on the fixed bracket 21.
The front side of the engagement hole 232 has a bowl shape and restricts the movement of the movable bracket 22, while the rear side thereof communicates with a gently inclined surface extending downward to lift the lever portion 231. Sometimes, the shaft 28 is slightly pushed forward along the inclined surface 233 so that the engagement is released.

The front bracket 25 is formed in a single plate shape, and engagement pieces 252 and 252 are formed at both ends thereof. The engaging pieces 252 and 252 engage with the slits 232 and 232, and the engaging pieces 253 and 253 formed on the bottom surface side engage with the holes formed on the bottom surface 221 of the movable bracket 22. A front bracket 25 is attached to the movable bracket 22.
A hole 251 is formed at the center of the front bracket 25. The hole 251 has a rectangular shape, and the lever portion 231 is exposed from the hole 252 to the front surface.
Further, a tool insertion hole 253 is formed in the lower center of the front bracket 25. This hole 253 is a semicircular hole opened on the bottom surface. In this example, the hole 253 only needs to have a width that allows the tip of a ratchet wrench to be inserted.

Next, the usage method and operation | movement of the elevator temporary enclosure concerning this embodiment are demonstrated.
First, the case where it moves from the state in which the temporary enclosure 1 is installed is demonstrated.
In the state where the temporary enclosure 1 is installed, the caster 2 is removed from the temporary enclosure 1, so the caster 2 is attached to the elevator temporary enclosure 1 in advance as shown in FIG. 3. As for the attachment method, the engagement pieces 211a and 211b of the caster 2 are inserted and attached to the insertion slit 11 formed in the lower part of the side surface of the elevator temporary enclosure 1.

In the state where the caster 2 is attached to the temporary enclosure 1, the caster 2 is in a state in which caster wheels 29 protrude from the side surface outside of the elevator temporary enclosure 1 as shown in FIGS. 4 and 5.
In this state, since the caster wheel 29 is protruding, the elevator temporary enclosure 1 itself is in a depressed shape, and the caster 2 is attached to the elevator temporary enclosure 1 in advance so that the bottom surface of the elevator temporary enclosure 1 is attached to the floor. The position has been adjusted.
Thus, in this state, the bottom surface of the elevator temporary enclosure 1 is directly placed on the floor.

In order to move the elevator temporary enclosure 1 from this state, first, the chin of the ratchet wrench 3 is inserted into the hole 253 as shown in FIG.
In this state, the movable bracket 22 rotates about the shafts 26 and 27 by pushing the ratchet wrench 3 downward as shown in FIG. At this time, since the caster wheel 29 is in contact with the floor surface, when the ratchet wrench 3 is pushed, the caster wheel 29 rotates in accordance with the rotation of the movable bracket 22. Thereby, it can be moved by rotation of the wheel 29 without applying a large force.

As the movable bracket 22 moves, the shaft 28 moves along the long hole 213. Thereby, the locus | trajectory and the width | variety which the movable bracket 29 moves are controlled.
Further, as the movable bracket 22 moves, the shaft 28 pushes the front portion of the locking bracket 23.
As a result, the locking bracket 23 rotates about the axis inserted through the hole 214 and is pushed up slightly.
Further, when the movable bracket 22 is further rotated, the shaft 28 is fitted into the engagement hole 232 of the locking bracket 23. Thus, when the shaft 23 fits into the engagement hole 232, the lifted locking bracket 23 returns to a substantially horizontal state, and the lever 231 of the locking bracket 23 moves from the hole 251 at the center of the front bracket 25. It will be in a state of protruding in a substantially horizontal state.
As a result, the movement of the shaft 28 is restricted, so that the movable bracket 22 does not move. Therefore, the caster wheel 29 can be easily moved by rotating the temporary provision 1 for the elevator. .

Next, the case where the elevator temporary enclosure 1 is installed after the movement is completed will be described.
First, as shown in FIG. 8C, the lever 231 is lifted up while inserting a ratchet wrench chin into the hole 253 and applying a force in the lift-up direction. As a result, the shaft 28 slides on the inclined surface 233 and is disengaged from the engagement hole 232.

When the shaft 28 is disengaged from the engagement hole 232, the movable bracket 22 and the shaft 28 move toward the outside of the elevator temporary enclosure 1 along the long hole 213.
As a result, the caster wheel 29 protrudes obliquely downward from the fixed bracket 21. As a result, the caster wheel 29 is disengaged so that the elevator temporary enclosure 1 slightly sinks and its bottom surface comes into contact with the floor. .
In this state, the engagement pieces 211a and 211b are removed from the insertion slits 11 formed in the lower part of the side surface of the elevator temporary enclosure 1. As a result, the caster 2 is removed from the temporary enclosure 1 and the elevator temporary enclosure 1 is self-supporting and stably installed.

Thus, according to the above-described embodiment, when the elevator temporary enclosure 1 is desired to be moved, the movable bracket 22 is fixed at the position standing in parallel with the fixed bracket 21, thereby being fixed to the bottom surface of the movable bracket. The caster wheel 29 can be rotated. This makes it possible to easily move the elevator temporary enclosure 1. In particular, even if the elevator temporary enclosure 1 is heavy, it can be easily moved by simply attaching the casters 2, and not only when the elevator temporary enclosure is removed, but also when it is desired to move it slightly for convenience of work. Can be moved easily and is very convenient.
Moreover, since the caster 2 can be removed when installing the temporary fence 1 for an elevator, the caster protrudes, and an operator or a passerby may be caught by this to get injured or disturb work. Absent.
Further, since the caster 2 can be easily rotated by using a tool, it is not necessary to attach an extra member to the caster 2, and the cost is low and it is easy to use.

  In the above-described embodiment, the example in which the movable bracket 22 is operated with the ratchet wrench with the sinus has been described. However, the tool is not limited thereto, and any tool that can operate the movable bracket 22 is not limited.

  The elevator temporary enclosure 1 may be a sliding door type or a door type and is optional.

  The temporary enclosure of the elevator hall according to the present invention has a configuration that can be easily moved and installed.
