  A damper 30 is interposed between the column 10 and the column 11 outside the column, and a damper 31 is interposed between the column 11 and the column 12 inside the column as shown in FIGS. 6 and 7. The support column 11 is extended upward by the damper 30, and the support column 12 is extended upward by the damper 31 as shown in FIG.

  Here, the damper 30 and the damper 31 are those having an extension function such as a gas damper or a hydraulic damper.

  The support column 11 and the support column 12 are configured to automatically extend when the locked state by the lock member 40 is released. After extension, the lock member 40 and the lock member 41 are automatically locked to maintain the extended state. This will be described in detail below.

  As shown in FIG. 6, the pressing member 40a constituting the locking member 40 is given a pressing force by a pressing spring 40b. Then, the pressing member 40a is inserted into the hole 10a, the hole 11a, and the hole 12a provided in the support column 10, the support column 11, and the support column 12, respectively, and the state of the storing stage before the extension is locked.

  On the other hand, when the handle portion 40c integrated with the pressing member 40a is pulled to release the fitting state of the pressing member 40a into the hole 11a and the hole 12a, the support column 11 and the support column 12 automatically extend upward. This is because the support column 11 is given a force that extends upward by the damper 30 and the support member 12 is given a force by which the support column 12 extends upward by the damper 31.

  FIG. 7 shows a state in which the column is extended and locked. The pressing member 40a is inserted into the hole 11b provided in the support column 11, and the extended state is locked. The locking in the extended state is automatically performed. That is, when the column 11 extends upward and the hole 11b comes to a position where it overlaps the hole 10a, the pressing member 40a to which the pressing force is applied by the pressing spring 40b fits into the hole 11b.

Similarly, the extended state of the column 12 is automatically locked by the lock member 41. That is, the pressing member 41a constituting the lock member 41 is given a pressing force by the pressing spring 41b. Then, when the support 12 is extended upward by the damper 31, and the hole 12a provided in the support comes to a position where it overlaps the hole 11c provided in the support 11, the pressing member to which the pressing force is applied by the pressing spring 41b. 41a fits into the hole 12a.
The following procedure is used to return the strut locked in the extended state to the original state.

  First, the handle portion 41c formed integrally with the pressing member 41a is pulled to release the locked state of the column 12 by the pressing member 41a. Then, the support column 12 is pushed down, and then the handle portion 40c of the lock member 40 is pulled to release the locked state of the support column 11 by the pressing member 40a.

  Then, the support pillar 11 is also pushed down by pushing down the support pillar 12, and when the hole 10a, the hole 11a and the hole 12a overlap, the pressing member 40a is automatically fitted into the hole 10a, the hole 11a and the hole 12a by the pressing force. It is. That is, it is locked in the state of the storage stage before expansion.

The positional relationship among the holes 10a, the holes 11a, and the holes 12a may be provided so that the damper 30 and the damper 31 overlap at the most contracted stage.
In the slow-down machine attachment device according to the present invention, the slow-down machine attachment arm is also configured so that the locked state is automatically released along with the extension of the support and is automatically locked after the automatic rotation. This will be described in detail below.

FIG. 8 shows a state where the arm is locked at the stage before the slow-down machine mounting arm turns. The slow down attachment arm 50 provided on the upper surface of the support column 12 is mounted so as to rotate around a shaft 51 attached to the support column 12. A spring 60 is interposed between the slow-motion machine mounting arm 50 and the wall portion 12 c provided on the support column 12. The spring 60, the slow-motion machine mounting arm 50, and the wall portion 12c are fixed, and the slow-motion machine mounting arm 50 is given a force that rotates by the spring 60, that is, a counterclockwise force in FIG. Yes.

  The locking state of the slow down attachment arm 50 before the rotation is maintained by the lock member 42. That is, the lock member 42 is given a pressing force upward by the pressing spring 42b, and the locking piece 42a is maintained in a state protruding from the upper surface of the column 12 by the pressing force. Then, the turning piece 42a is prevented from turning by the locking piece 42a.

And this latching piece 42a is connected with the string 42c, and this string 42c is connected with the support | pillar 10 which exists below as shown in FIG.2 and FIG.5. The string 42c is pulled downward as the column 11 and the column 12 are extended upward, and the locking piece 42a is also moved downward relative to the column portion where the arm is provided. The state is released (see FIG. 9).

  Note that the lower end of the string 42c does not necessarily have to be connected to the support column 10, and may be any position that can apply a force to pull down the locking piece 42a with the extension of the support column.

  The slow down attachment arm 50 is configured to be automatically locked after turning. FIG. 9 shows the locked state after the rotation. The lock after the rotation is performed by the lock member 43. The pressing member 43a constituting the lock member 43 is given a pressing force by a pressing spring 43b. Then, when the slow down attachment arm 50 turns and the hole 50a provided in the slow down attachment arm 50 and the pressing member 43a overlap each other, the pressing member 43a is inserted into the hole 50a by the pressing force. As a result, the turning state is locked. The hole 50a is provided at a position that overlaps with the pressing member 43a in a state in which the slow down attachment arm 50 is rotated approximately 90 degrees from the housed state. In this way, it automatically turns and locks as the column extends.

  To release the locked state after turning, the handle 43c formed integrally with the pressing member 43a is released from the insertion state with respect to the pulling hole 50a, and the slow-down machine mounting arm 50 is returned to the original state, FIG. In other words, it rotates clockwise. In this state, when the support column is pushed downward, the locking piece 42a constituting the lock member 42 protrudes by the pressing spring 42b and is locked in a state before turning.

  An annular portion 52 is provided in the vicinity of the tip of the slow down attachment arm 50. A slow down machine is attached to the ring portion 52 for use.

In the present invention, it is preferable that a trapping 70 that is automatically rotated to make evacuation easier . As shown in FIGS. 1 and 4, the trap 70 is installed with a pair of plate-like bodies 71 fixed to a wall surface 80. The plate-like body 71 includes a fixing surface 71a that is fixed to the wall surface 80, and a step mounting surface 71b that rises perpendicularly from the fixing surface 71a.

  The step platform 72 and the step platform 73 are provided so as to be rotatable with respect to the step mounting surface 71b.

A link member 74 and a link member 75 are interposed between the step 72, the step 73 and the step attachment surface 71b, respectively. As shown in FIG. 3, the end of the link member 74 is bent to form a locking portion 74a, and the end of the link member 75 is bent to form a locking portion 75a. The locking portion 74a and the locking portion 75a are provided so as to be loosely inserted into a long hole 71c provided in the step mounting surface 71b and to slide up and down. Further, since the link member 74 and the step platform 72 and the link member 75 and the step platform 73 are provided so as to be rotatable, the locking portion 74a and the locking portion 75a are elongated holes 71c as the step platform 72 and the step platform 73 are rotated. It will slide up and down inside. And since the step 72 and the step 73 are connected by the link member 76, both rotation will interlock | cooperate.

The trap attached to the present invention configured as described above is configured to be automatically deployed when the locked state is released. This will be described in detail below.

  11 and 12 show the locked state of the trap. Circular holes 71e and 71e are provided in the pair of protrusions 71d and 71d provided on the step mounting surface 71b near the upper end of the long hole 71c. And the pin 77 is loosely inserted over both the said circular holes 71e * 71e, and the state which folded the trap is locked.

  That is, when the step 73 is rotated and brought into the folded state, the locking portion 75a slides upward in the long hole 71c. By loosely inserting the original pin 77 in such a state over the circular holes 71e and 71e, the locking piece 75a is prevented from sliding downward, so that the stepped bed 73 is maintained and locked.

  Since the step 72 and the step 73 are linked by the link member 76, when the step 73 is locked in the folded state, the step 72 is also locked in the folded state at the same time.

  To release such a locked state, the pin 77 is pulled out from the circular hole 71e. When the pin 77 is pulled out, the step 72 and the step 73 are rotated and deployed by the own weight of the step 72 and the step 73 and the tension spring 78 provided below the step 73 and applying a pulling force to the step 73 downward. is there.

Since the string 79 tied to the pin 77 is connected to the box 90 (represented by the alternate long and short dash line in FIG. 2) that covers the slow down attachment device according to the present invention, the box 90 during evacuation. When the cable is removed, the string 79 is pulled and the pin 77 is automatically pulled out and the platform is automatically deployed. In other words, the trap can be automatically deployed and installed. However, this box 90 does not constitute claims 3 and 4.

In the above description, two steps are provided, but this is not a limitation. It is preferable to provide the number of steps according to the height of the wall surface to be stepped over.
Further, the box 90 and the handle portion 40c of the lock member 40 in the slow down attachment device are connected by a string 40d. Therefore, the string 40d is pulled by removing the box 90 at the time of evacuation, and the handle portion 40c is pulled accordingly, and the locked state of the column is released. In other words, the column is automatically extended.

Second Embodiment
Hereinafter, the second embodiment will be described with reference to the drawings with a focus on differences from the first embodiment.
FIG. 13 is a partially broken front view of a slow down attachment device according to the present invention, FIG. 14 is a front view of a state in which a support column is extended and a wrap is deployed, and FIG. 15a is a slow down attachment arm before turning. FIG. 15b is an explanatory view of an essential part in the vicinity of a slow-down machine mounting arm after turning, FIG. 16 is an explanatory view of an essential part in the vicinity of a lap, and FIG. FIG. 17b is a right side view of the same, FIG. 17c is a right side view of a state in which the locked state is released, and FIG. 18 schematically shows the relationship between the rod body and the chain. FIG.

The support column 100, the support column 101, and the support column 102 are hollow columnar bodies, respectively. As shown in FIGS. 13 and 14 , the support column 101 is stored in the support column 100, and the support column 102 can be stored in the support column 101. ing. The difference from the first embodiment is that not only the damper 104 that extends the column 102 but also the damper 103 that extends the column 101 is provided inside the column 100 instead of the outer wall surface of the column 100. As the damper 103 and the damper 104, those having an extension function such as a gas damper and a hydraulic damper are used.

  The locked state during storage and the locked state during extension in the second embodiment are slightly different from those in the first embodiment. That is, the locked state at the time of storage is maintained by locking the locking bar 108 attached to the shaft base 107 provided on the upper end surface of the column 102 to the locking member 109 provided on the column 100. It is.

As shown in FIG. 17 , the locking member 109 attached to the side wall of the support column 100 includes a fixed plate 109a, a movable plate 109b, a rotating shaft 109c, and a pressing spring 109d. As shown in FIG. 17b , the latching bar 108 is fitted into the recess of the movable plate 109b, whereby the storage state shown in FIG. 13 is locked. Here, the movable plate 109b is applied with a pressing force in the clockwise direction around the rotation shaft 109c in the figure by a pressing spring 109d into which the rotation shaft 109c is loosely inserted.

  When releasing the storage lock state, the rotating plate 109b is rotated against the pressing force. Then, the locking state by the locking member 109 with respect to the locking rod 108 is released, and the support column 101 and the support column 102 are extended by the damper.

The rotation of the movable plate 109b is performed by removing the box 110 that covers the support column. Here, the box body 110 is shown by a one-dot chain line in FIGS . 13 and 14. When the box 110 is removed, the rotation plate 109b connected to the box 110 via the chain 111 rotates about the rotation shaft 109c. That is, the storage lock state is thereby released.

  Unlike the locking method in the state in which the column is stored, the locking method in the state in which the column is extended is the same as that of the first embodiment. That is, the lock member 105 and the lock member 106 are configured by a pressing member, a pressing spring, and the like as in the first embodiment. Then, in a state where the column is extended, the pressing member constituting the lock member 105 is fitted into the hole provided in the column 101, and the pressing member constituting the lock member 106 is also fitted into the hole provided in the column 102. In this way, the extended state is locked.

In the second embodiment, similarly to the first embodiment, the slow-down machine mounting arm 112 is automatically released from the locked state as the column is extended, and is automatically locked after the automatic rotation. Then, the method / member that is automatically unlocked and automatically locked is the same as in the first embodiment. That is, as shown in FIG. 13 and FIG. 14, the string 42 c is pulled downward as the column 101 and the column 102 are extended upward, and the locking piece 42 a is also moved relative to the column portion where the arm is provided. The locked state is released by moving relatively downward. However, the method and members for automatically rotating the slow down attachment arm 112 are different from those in the first embodiment. Hereinafter, this difference will be described.

FIG. 15a shows a main part in the vicinity of the slow down attachment arm 112 before turning. A tension spring 113 is interposed between the shaft base 107 and the slow down attachment arm 112. This tensile slow disembarkation mounting arm 112 by a spring 113, a force that rotates counterclockwise is imparted in terms of the Figure 15. Therefore, if the locked state is released, that is, with the extension of the support column, the slow-motion machine mounting arm 112 automatically turns.

Ramp 114 according to claim 4, wherein in the second embodiment, the internal as shown in FIG. 16 is a box body of the cavity. In this hollow portion, as shown in FIG. 13, the slow-down machine 115 at the time of storage is stored. The trap 114 is automatically deployed when the column is extended. The method of automatic rotation is as follows.

  The flange portion 100a provided on the outer wall of the support column 100 and the trap 114 are connected by a hinge 116. The trap 114 can be rotated by its own weight in a clockwise direction in FIG. . However, at the time of storage, the plate material 117 attached to the slow-motion machine attaching arm 112 is inserted into the hollow portion, and the development is suppressed by contacting and supporting the inner wall surface of the trap 114.

  However, when the plate material 117 comes out of the cavity portion of the trap 114 with the extension of the support column, there is no expansion restraining force on the trap 114 by the plate material 117, and the trap 114 automatically expands by its own weight. At this time, if it is suddenly deployed, there is a risk of harming persons in the vicinity or damage to the device or the floor. Therefore, the damper 118 is provided so as to unfold gently. Here, the damper 118 is attached over the back side of the trap 114 and the back side of the column 100 in FIG. As the damper 118, a gas damper, a hydraulic damper or the like having an extension function is used.

Ramp Thus 114 automatically deployed with the extension of the strut is the side 114a in FIG. 16 is springboard surface. That is, it is possible to escape from the building using the side surface 114a as a step.

  In the second embodiment, the body support belt constituting the slow-down machine is configured to automatically drop as the slow-down machine mounting arm 112 turns. This will be described in detail below. The gentler 115 is hung on a ring member 119 provided in the vicinity of the tip of the gentler attachment arm 112. And it is accommodated in the trap 114 at the time of accommodation.

  The slow-down machine 115 includes a wire 115b having body support belts 115a at both ends, and the body support belt 115a on one end side is wound around a reel 115c together with the wires 115b. The reel 115c is hung on the slow-motion machine mounting arm 112 by gently inserting the chain 120 into the hole 115d.

  Here, one end of the chain 120 is fixed to the slow-motion machine mounting arm 112, but the other end is supported by a rod 121.

The method of supporting the chain 120 by the rod body 121 is to loosely insert the rod body 121 into the hole 120b of the ring body 120a constituting the chain 120. FIG. 18 schematically shows such a state. Then, when the rod body 121 is retracted, the rod body 121 is removed from the hole 120b, that is, the state where the chain 120 is supported by the rod body 121 is released. As a result, the chain 120 is removed from the hole 115d of the reel 115c, and the reel 115c around which the body support belt 115a or the like is wound falls outside the building.

This series of operations is performed along with the turning of the slow down attachment arm 112. That is, with the extension of the support column, the slow down attachment arm 112 automatically turns. At this time, since one end of the rod 121 is attached at a position shifted from the center position of the shaft base 107 as shown in FIG. 15 , the plate 121 a that supports the other end of the rod 121 and the shaft base 107. The distance from the upper rod body attachment position changes as the slow down attachment arm 112 turns. That is, L2 is longer than L1.

  Because of this positional relationship, the rod 121 moves backward in the direction of the shaft base 107 when viewed from the place of the plate 121a. With this operation, the rod 121 is removed from the chain 120. That is, when the slow-down machine mounting arm 112 turns and the vicinity of the tip of the slow-down machine mounting arm 112 comes out of the building, the reel 115c falls out of the building. In other words, the slow down machine is set to a usable state.
