[Detailed description of the invention]

[0001]

[Industrial Application Field] The present invention turns an evacuation device extension arm from which a refugee or other evacuation device that can be hung by a refugee to descend in the event of a fire can be hung from the stowed position to the extended position. The present invention relates to a mounting fixture for evacuation equipment to be fixed.

[0002]

2. Description of the Related Art A cannula fixed to a base end of a mounting plate of a conventional foldable evacuation device overhanging arm can be swiveled about a vertical shaft mounted between upper and lower brackets of a substrate fixed to a building side, and Evacuation equipment fittings fitted in a certain range so as to be able to move up and down are commonly used. For example, Shoko 54-1
See 5920 publication.

In this evacuation device mounting bracket, since the evacuation device extension arm must be fixed at the extension angle position,
A groove in which the lower end of the mounting plate and the sleeve is fitted by the action of gravity is recessed in the lower bracket side when the arm is extended, but the extended angle position of the arm is adjacent to the window or veranda of the building. It must be adjustable depending on its position relative to the wall.

[0004]

However, as shown in FIG. 8, the mounting plate 1 and the lower shaft 5 between the lower tube 5 and the mounting plate 1 of the arm for extending the evacuation device are attached to the lower end of the mounting plate and the lower tube 5. An arm stopper 7 having a groove 7a in which an upper part can be fitted is rotatably fitted on an upper surface thereof, and a plurality of projections 7c are provided in a gear shape on at least a part of the outer periphery of the arm stopper. If a pair of arm stopper fixing holes 9 with which the projections 7c are respectively engaged are formed in the substrate 3 so as to prevent the rotation of the arm stopper, the groove 7a or the overhanging angle position of the arm with respect to the substrate may be incorrect during the transportation of the mounting bracket. At the same time, there is no danger of getting out of order, but on the other hand, when the mounting bracket is actually mounted on a building, evacuation equipment suspended from the mounting bracket often interferes with foreign matters such as vertical pipes of rain gutters, telephone lines, or planting trees. Evacuees cannot safely descend Results in a case. In such a case, the mounting bracket must be returned to the factory and disassembled, and then the arm extension angle position must be adjusted, which significantly increases the man-hour required for adjusting the arm extension angle position of the mounting bracket. Occurs.

[0005] The present invention addresses this problem and eliminates the risk that the extension angle position of the arm for extension of the evacuation device during transportation of the assembled mounting bracket will be accidentally disturbed, and it is necessary to adjust the angle position of the arm extension. It is an object of the present invention to make it possible to easily perform the operation at the installation site of the evacuation equipment according to (1).

SUMMARY OF THE INVENTION The present invention relates to an arm stopper.
Arm so that it can be tilted at a fixed angle to the horizontal position.
The inner diameter of the vertical shaft insertion hole of the stopper is larger than the outer diameter of the vertical shaft.
Position the center of gravity of the arm stopper inside the vertical shaft insertion hole.
Is, and a plurality of projections provided on the gear-shaped in at least a part of the outer circumference of the Amusutotsupa is, the engagement piece that engages to prevent the horizontal plane rotation of Amusutotsupa was planted on the lower bracket, the Amusutotsupa With the upper surface in contact with the lower end of the cannula at the upper limit position, the projection is engaged with or disengaged from the engagement piece depending on whether the arm stopper is in the horizontal position or in the inclined position inclined at the predetermined angle. as such, the lower end of the mounting plate and sleeve of the upper limit position above the engaging piece
It is obtained by position.

[0007]

According to the present invention, when the evacuation device mounting bracket is transported, the folded evacuation device extension arm mounting plate is pivoted to a position where it is stored in the storage cover which can be opened and closed on the board side. By doing so, since the mounting plate and its proximal end tube are transported so as not to face the groove formed on the arm stopper, when transporting while maintaining the vertical axis in a substantially vertical position, the mounting is performed. Even if the mounting plate or arm stopper of the arm is displaced up and down between the upper limit position and the lower limit position along the vertical axis due to the up and down and left and right movement of the bracket.
The arm stopper is always maintained at a substantially horizontal position, and the projection of the arm stopper engages with the engagement piece in a set state to maintain the set angular position of the groove of the arm stopper.

Further, since the center of gravity of the arm stopper is located in the vertical insertion hole, even when the mounting bracket is transported while the vertical axis is maintained at a substantially horizontal position, the arm stopper is moved by its own weight to the vertical insertion hole. Since the inner wall is always urged to return to the vertical state in which the inner wall comes in contact with the vertical axis, the engagement state between the projection of the arm stopper and the engagement piece remains as set, and the angle at which the groove of the arm stopper is also set. Hold position.

When the mounting bracket is to be mounted on the wall of a building or when it is necessary to adjust the groove or arm extension angle position after mounting, the mounting plate and the cannula are pushed up to the upper limit position where they come into contact with the upper bracket. Then, after the arm stopper is tilted in a direction in which the projection is disengaged from the engagement piece, the arm stopper is brought into contact with the lower end of the sleeve along the vertical axis, so that the projection is disengaged from the engagement piece and the arm stopper is turned. Since the arm stopper can be moved, the arm stopper is rotated so that the groove is at a desired angular position, and then the arm stopper is returned to the horizontal position to engage the protrusion with the engaging piece.
