Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a mounting device for an evacuation loom used for evacuation from windows of a building or the like in an emergency.

2. Description of the Related Art There is conventionally known a mounting device for an evacuation and abatement, which is usually folded and stored in a building, and is deployed in an emergency to support the slowdown outside the building.
For example, the conventional mounting apparatus for a slowdown shown in FIGS. 6-8 fixes the pair of support pieces 2 and 3 to the base plate 1 and turns the rotating body 4 to the pivot shaft 4 passed between the support pieces 2 and 3 5 is rotatably mounted. A pair of arm support pieces 6 and 7 is fixed to the rotating body 5 and the arm 9 is rotatably supported by a shaft member 8 extending between the arm support pieces 6 and 7. And at the tip of this arm 9 is provided a hanging tool 10 for hanging the slowdown machine at the time of evacuation.

Further, a stopper hole 11 is formed in the lower support piece 3 for supporting the rotation shaft 4 of the rotation body 5, and a pin case 12 is fixed to the rotation body 5.
As shown in FIG. 7, the pin case 12 is a metal cylindrical member accommodating the stopper pin 13, and the tip end of the stopper pin 13 faces the opening 12 a on the tip end side. A spring member 14 is interposed between the base end of the stopper pin 13 and the base end of the pin case 12, and the stopper pin 13 is subjected to a spring force in the direction of pushing its tip out from the opening 12a. Therefore, the tip of the stopper pin 13 is pressed against the surface of the support piece 3.

Furthermore, a wire 15 is connected to the base end side of the stopper pin 13, and the wire 15 is drawn out from the small hole 12 b on the base end side of the pin case 12 and connected to the ring 16. The wire 15 and the ring 16 are used to pull back the stopper pin 13 whose tip is protruded from the pin case 12.
The pin case 12 and the stopper hole 11 are provided at a position shifted by 180 ° in the rotating direction on the same circumference centering on the axial center line of the rotating shaft 4 in the folded state of FIG. It is done.

In the case where such a mounting device for evacuation shelters is expanded from the folded state of FIG. 6 to the use state, it is performed as follows.
First, the arm 9 is pivoted in the arrow A direction so as to lift the tip end of the arm 9. When the arm 9 is rotated, a bolt 17 fixed to an end of a support rod (not shown) linked to the arm 9 moves along the linear guide holes 6a and 7a of the arm support pieces 6 and 7. When the arm 9 is substantially horizontal, the bolt 17 is located at the end of the guide holes 6a and 7a to prevent the arm 9 from falling. Although the guide holes 7a of the arm support piece 7 are not shown, they are formed at positions opposite to the guide holes 6a of the arm support piece 6 similarly to the guide holes 6a.

When the arm 9 is lifted as described above, the arm 9 is turned in the direction of arrow B, and the rotating body 5 is rotated to project the horizontal arm 9 out of the window w as shown in FIG.
FIG. 8 shows a state in which the rotating body 5 is rotated 180 ° from the base plate 1 attached to the wall surface 100 adjacent to the window w.
At this time, the pin case 12 moves together with the rotating body 5 rotated 180 ° and faces the stopper hole 11 formed in the support piece 3, so the stopper pin 13 is moved by the elastic force of the spring member 14. It enters inside and regulates rotation of the rotating body 5.

  Thereby, the rotation of the rotating body 5 is restricted in a state in which the arm 9 kept in the horizontal state is protruded from the window w to the outside, and the loose implement can be attached to the suspension tool 10 and used.

JP, 2006-000168, A Unexamined-Japanese-Patent No. 09-322945 gazette

  In the above-described conventional mounting device for evacuation relaxation, the stopper hole 11 for restricting the rotation of the rotating body 5 supporting the arm 9 is directly formed in the support piece 3. Therefore, the positional relationship between the pin case 12 and the stopper hole 11, that is, the positional relationship between the stopper hole 11 and the stopper pin 13 is fixed. Therefore, the angle of the arm 9 in use is also determined in advance.

  On the other hand, the situation outside the window w differs depending on the building. For example, as shown in FIG. 8, when the arm 9 is in a use state in which the arm 9 protrudes from the window, an obstacle may be present immediately below the fixture 10. In such a case, it is necessary to change the position of the stopper hole 11 and adjust the projection angle of the arm 9 with respect to the window w to avoid obstacles, since it will not be possible to evacuate using a slowdown machine .

However, since the said apparatus makes the said stopper hole 11 beforehand in a factory, and can be shipped, the position of the stopper hole 11 can not be easily changed in the field.
If the special situation at the site is known in advance, the stopper hole can be formed as a special order item. However, in this case, the installer has to go to the site in advance to measure the special situation in advance, which causes a problem that it takes time and effort.

  In addition, when the installation worker arrives at the site and the special situation is found for the first time, the device must be brought back to the factory once to recreate the stopper hole 11, and then the device must be brought to the site again. If this is done, there will also be the problem that it takes too much time and the business becomes extremely inefficient.

  Although it is conceivable to make the stopper hole 11 at the site while considering the special situation at the site, it is almost impossible. If it is intended to form the stopper hole 11 on site, the lower support piece 3 must be removed. When the lower support piece 3 is removed, the arm 9 integrated with the pivoting member 5 must also be removed. However, since the base member 1 made of a metal material, the pivoting member 5 and the arm 9 are relatively heavy, they can not be accurately assembled without a special tool. Furthermore, the support piece 3 having the stopper hole 11 in the field must be welded to the base plate 1. As such, it is almost impossible to form the stopper hole 11 in the field.

  An object of the present invention is to provide a mounting device for an evacuation locker capable of easily adjusting the projecting direction of the arm at the installation site.

  According to a first aspect of the present invention, there is provided a base member mounted directly or indirectly in a building such as an inner wall, a pair of opposed support pieces fixed to the base member, and a pivot shaft provided between the opposed support pieces. And a pivotally supported member pivotally supported from the folding position to the deployed position, and the pivotally supported member mounted on the pivotally supporting member and folded about the shaft member orthogonal to the pivotal axis. The arm rotatably supported between the use states, the use state holding mechanism for keeping the use state of the arms, and any one of the above-mentioned opposite support pieces can be rotated relative to the opposite support pieces And a stopper pin that rotates integrally with the rotation support member and rotates around the rotation axis while being in elastic contact with the surface of the adjustment member. Then, the positional relationship between the stopper pin and the stopper hole can be adjusted by rotating the adjustment member, and when the rotation support member rotates in the deployment direction and the stopper pin reaches the position of the stopper hole The tip end of the stopper pin enters into the stopper hole, and the rotation of the rotation support member is restricted.

  In a second aspect of the invention, the adjusting member is a plate member which penetrates the pivot shaft of the pivot support member and is rotatably supported about the pivot shaft, with respect to the one opposing support piece. And a fixing means for fixing the adjusting member at an arbitrary rotation position.

  According to a third aspect of the invention, the adjusting member includes an arc-shaped portion centered on the rotation center of the adjusting member on an outer periphery thereof, and a plurality of gear grooves are provided in the arc-shaped portion. The present invention is characterized in that it comprises: the above-mentioned gear-like groove; and a stopping member which is fitted to this gear-like groove to fix the rotational position of the above-mentioned adjusting member.

In this invention, the stopper hole provided on the side of the base member is formed in the adjustment member separate from the base member, and this adjustment member is made rotatable. Therefore, only by adjusting the rotational position of the adjustment member, The positional relationship between the stopper hole and the stopper pin can be easily changed.
Therefore, the rotation angle of the rotation support member provided with the stopper pin can be adjusted on the spot according to the situation, and the projecting direction of the arm can be adjusted.
As described above, the position of the stopper hole can be easily changed, and there is no need to take it back to the factory as in the conventional case, so the installation workability of this device is improved.
In addition, in the process of descending with the slowdown gear attached to the tip of the arm, the evacuee can evacuate safely without colliding with an obstacle or the like.

  According to the second aspect of the invention, the adjustment member can be rotatably supported by penetrating the rotation shaft of the rotation support member. The position of the stopper hole can be easily adjusted by rotating the adjustment member around the rotation axis.

According to the third aspect of the present invention, the rotational position of the adjustment member can be adjusted according to the distance between the gear grooves formed on the outer periphery of the adjustment member. Therefore, the projection angle of the arm can be set with accuracy according to the distance between the gear grooves.
The smaller the gap between the gear grooves, the finer the adjustment of the rotational position of the stopper hole, and as a result, the finer the projecting direction of the arm. In addition, since the arm has a certain length, even if the change of the rotation angle of the arm is small, there is a large difference in the position of the tip of the arm. Therefore, in order to adjust the arm tip position to a required position, it is necessary to be able to more finely adjust the rotational position of the stopper hole.

One embodiment of the present invention will be described with reference to FIGS.
In this embodiment, the same reference numerals as those in FIGS.
The mounting apparatus for evacuation escapement of this embodiment is also used by fixing the base plate 1 to the wall surface 100 adjacent to the window w as shown in FIG.
FIG. 1 shows the folded state when not in use, and FIGS. 2 and 3 show the expanded state when used.

Also in the apparatus of this embodiment, a pair of support pieces 2 and 3 which are the opposing support pieces of the present invention are fixed to the base plate 1 as in the prior art. The rotating body 5 is rotatably supported by the rotating shaft 4 passed between the support pieces 2 and 3.
Further, arm supporting pieces 6 and 7 are fixed to the rotating body 5, and a shaft member 8 orthogonal to the rotating shaft 4 is passed to the arm supporting pieces 6 and 7. Is rotatably supported.

Guide holes 6a and 7a are formed in the arm support pieces 6 and 7, and a bolt 17 linked to the arm 9 is passed between them via a support rod (not shown). When the arm 9 is rotated in the arrow A direction, the bolt 17 moves along the linear guide holes 6a and 7a of the arm support pieces 6 and 7. Then, when the arm 9 passes through the horizontal state and is lifted until the tip thereof is positioned slightly above the horizontal, and the bolt 17 is allowed to pass through the tops of the guide holes 6a and 7a and then returned horizontally, A bolt 17 is positioned at the hooked end portions 6b and 7b of the guide holes 6a and 7a to prevent the arm 9 from falling. In this embodiment, the guide holes 6 a and 7 a and the bolt 17 constitute a use state holding mechanism of the arm 9.
Then, when the arm 9 is returned from the deployed position to the folded position, the arm 9 is slightly lifted so that the bolt 17 gets over the tops of the guide holes 6a and 7a.

Further, in this embodiment, an adjusting board 18 as an adjusting member is provided between the lower support piece 3 and the rotating body 5. The adjusting plate 18 is a metal plate member, and as shown in FIG. 5, an axial hole 19 is formed at the center. The rotation shaft 4 is inserted into the shaft hole 19, and the adjustment board 18 is rotatably supported around the rotation shaft 4.
Further, a plurality of gear grooves 18 a are formed on the outer periphery of the adjusting plate 18. The gear grooves 18a are formed along the circumference of the adjusting plate 18 at a pitch of a central angle α.
In this embodiment, the gear groove 18a is formed not in the entire circumference of the adjusting plate 18 but in the range of about two thirds of the outer periphery, but the range in which the gear groove 18a is formed is not particularly limited.
Further, a stopper hole 20 into which the stopper pin 13 is inserted is formed in the adjusting plate 18. A tapered surface 18 b which descends toward the center is formed around the stopper hole 20 so as to guide the stopper pin 13 to the stopper hole 20.

On the other hand, although the pin case 12 is fixed to the rotating body 5 by welding or the like, the pin case 12 is a metal cylindrical member accommodating the stopper pin 13 as in the conventional case (see FIG. 7) .
Since the opening 12a of the pin case 12 is in contact with the surface of the adjusting plate 18 in the folded state shown in FIG. 1, the tip of the stopper pin 13 is resiliently attached to the adjusting plate 18 by the spring member 14. It is in contact.

Further, the lower support piece 3 is formed with an axial hole (not shown) through which the rotational shaft 4 is inserted, and two screw holes 3a, 3b along the outer periphery of the adjusting board 18. The screw hole 3a of one of the screw holes 3a and 3b is made to coincide with the gear groove 18a of the adjusting plate 18, and the set screw 21 is screwed in to fix the adjusting plate 18 to the support piece 3.
The set screw 21 may be screwed in from below the support piece 3 so that the tip thereof is fitted to the gear groove 18a, or the set screw 21 may be fitted along the gear groove 18a from the adjustment plate 18 side. It may be screwed into the screw hole 3a.
However, the end of the locking screw should not protrude from the upper surface of the adjusting disk 18 so that the tip or head of the locking screw 21 does not interfere with the movement of the rotating screw 5 moving on the adjusting disk 18. There must be. Therefore, when screwing in the set screw from the adjustment plate 18 side, it is necessary to use a holed screw or the like whose head is not enlarged.

Hereinafter, the relationship between the screw holes 3a and 3b formed in the support piece 3 and the gear groove 18a and the method of adjusting the position of the adjusting plate 18 will be described with reference to FIG.
FIG. 5 is a plan view of the adjusting board 18, but the positions of the screw holes 3a and 3b when the adjusting board 18 is provided on the support piece 3 are indicated by alternate long and two short dashes lines. In FIG. 5, one screw hole 3a and a specific gear groove 18a are made to coincide, but a support piece is selected depending on which gear groove 18a and the screw hole 3a are made to coincide among a plurality of gear grooves 18a. The position of the stopper hole 20 on 3 can be adjusted.
As described above, since the gear grooves 18a are formed at the pitch of the central angle α, the rotational position of the stopper hole 20 is adjusted in units of the central angle α by the combination of the screw holes 3a and the gear grooves 18a. it can.

The other screw hole 3b is formed at a position shifted by a central angle [1.5 × α] with respect to the screw hole 3a. Therefore, when the gear-like groove 18a is made to coincide with the screw hole 3b, the stopper hole 20 is shifted by a half pitch from the case where the screw hole 3a is used, that is, the central angle [0.5 × α]. It can be fixed. Thus, the stopper holes 20 can be adjusted in half pitch units of the gear grooves 18a by the screw holes 3a and 3b.
And, in this embodiment, the fixing means of the present invention is constituted by the screw holes 3a, 3b, the gear-like groove 18a and the set screw 21.

  Further, in this embodiment, in the folded state shown in FIG. 1, the pin case 12 and the stopper hole 20 are shifted by 180 ° at a central angle centering on the central axis of the pivot shaft 4. The adjustment screw 18 is screwed into the screw hole 3 a to fix the adjusting plate 18. The positions of the pin case 12 and the stopper pin 13 at this time are shown by a two-dot chain line in FIG. Therefore, when the pivoting body 5 pivots in the direction of arrow B until the pivoting angle θ becomes 180 °, the pin case 12 and the stopper pin 13 fixed to the pivoting body 5 coincide with the stopper holes 20 of the adjustment board 18 The stopper pin 13 enters the stopper hole 20 by the elastic force of the spring member 14.

The procedure for bringing this device into the deployed state, which is in use, is the same as in the prior art.
That is, if the arm 9 is rotated in the direction of arrow A in FIG. 1 and held in the horizontal state, and then the rotating body 5 is rotated in the direction of arrow B, the arm 9 is moved from the window w as shown in FIG. It can be made to protrude outside. Then, when the pivoting body 5 is pivoted from the folding position until the pivoting angle θ becomes 180 °, the stopper pin 13 enters the stopper hole 20 of the adjustment board 18 and the pivoting of the pivoting body 5 is restricted. Be done.

  In the above, the case where the stopper pin 12 and the stopper hole 20 are shifted 180 degrees in the central angle in the folded state of the device shown in FIG. 1 has been described, but the positional relationship between the stopper pin 12 and the stopper hole 20 is The adjustment can be made by the fixed position of the adjusting plate 18 as described above. That is, the rotational position of the adjusting plate 18 is adjusted in half pitch units of the gear-like groove 18a by fixing the adjusting plate 18 by aligning any of the gear-like grooves 18a of the adjusting plate 18 with the screw holes 3a or 3b. Can be adjusted.

Then, if the rotation angle of the rotation body 5, that is, the rotation angle θ until the stopper pin 12 coincides with the stopper hole 20 is set according to the position of the adjustment board 18, the arm 9 is moved in the direction according to this angle θ. It can be made to protrude. For example, if the rotation angle θ is smaller than 180 °, the arm 9 can be obliquely projected from the window w, as shown by a two-dot chain line in FIG.
As described above, according to this embodiment, the stopper pin 13 and the stopper hole can be formed simply by aligning the screw hole 3a or 3b formed in advance in the support piece 3 with the gear groove 18a and fixing them with the set screw 21. The positional relationship with 20 can be adjusted. Therefore, it is not necessary to take the apparatus back to the factory in order to change the position of the stopper hole 20 according to the field conditions.

  Then, when this device is folded from the use state, after the stopper pin 12 is pulled out from the stopper hole 20, the rotating body 5 can be turned in the reverse direction to the arrow B to be in the folded state. In order to pull out the stopper pin 13 from the stopper hole 20, the wire 15 may be pulled by the ring 16 on the pin case 12, and the stopper pin 12 may be pulled up against the spring force of the spring member 14.

Reference numeral 2a in FIGS. 1, 2 and 4 is an axial hole for supporting the pivot shaft of the pivoting support member for pivoting the arm 9 in the horizontal state in the direction opposite to the arrow B in FIG. is there. The lower support piece 3 is formed with a shaft hole 3c at a position opposite to the shaft hole 2a for supporting the pivot shaft for reverse rotation.
Furthermore, screw holes 3 d and 3 e for fixing the adjusting member 18 are formed around the shaft hole 3 c of the lower support piece 3.

As described above, since the shaft holes 2a and 3c and the screw holes 3d and 3e for reverse rotation are formed in the support pieces 2 and 3, the turn for reverse rotation for rotating the arm 9 in the direction opposite to the arrow B When using a dynamic support member, its rotational axis may be inserted into the shaft hole 19 of the adjustment board 18 to adjust the relative position between the stopper pin 12 and the stopper hole 20 depending on the fixed position of the adjustment board 18 it can.
As described above, since the reverse rotation shaft holes 2a and 3c and the screw holes 3d and 3e are formed in the support pieces 2 and 3, the rotation support members for rotation in the arrow B direction and for reverse rotation are attached. In this case, the base plate 1 to which the support pieces 2 and 3 are fixed can be made common.
However, it is not essential to share the support pieces 2 and 3 for supporting the rotation support member for reverse rotation.

In the above embodiment, the gear-like groove 18a is formed on the outer periphery of the adjusting plate 18, and the adjusting plate 18 is fixed to the support piece 3 as the base member by the gear-like groove 18a and the locking screw 21. However, the fixing means for fixing the adjusting plate 18 to the base member is not limited to the above embodiment. For example, instead of the screw holes 3a and 3b, a small hole may be formed in the support piece 3, and a stop pin may be press-fit into this small hole to position the adjusting board 18.
Further, instead of the gear-like groove 18a, a plurality of through holes may be formed in the adjusting plate 18, and a fixing screw or a locking pin may be inserted into the through holes to fix the adjusting plate 18 Means may be used.

Moreover, although the adjusting board 18 is provided between the lower support piece 3 and the rotating body 5 in this embodiment, the adjusting board 18 is provided between the rotating body 5 and the upper support piece 2. May be In that case, it is necessary to form a screw hole or the like for fixing the adjusting plate 18 to the upper support piece 2.
Furthermore, although the example which attached the said base plate 1 to the wall surface 100 which becomes flush with the opening surface of the window w is demonstrated here, the surface which attaches the base plate 1 may not be flush with the window w. Even if the mounting surface of the base plate 1 is at any angle with respect to the window w, if the position of the stopper hole 20 is adjusted by rotating the adjusting plate 18, the tip of the arm 9 is positioned at the target location be able to.

  It can easily cope with a building where there is an obstacle under the window.
