Japanese Utility Model Publication No. 4-111359 ([Claim 1], FIG. 4)

  However, when preparing the evacuation by setting the mounting device 1x as described above from the retracted state of FIG. 12A to the used state of FIG. 12B, the weight of the arm portion 20x is large. The operation to push out requires a lot of power, and there was a problem that it was difficult for women and elderly people. Further, when using this attachment device, the operator stands on the side of the attachment device 1x, lifts up the arm portion 20x, then turns around the indoor end portion of the arm portion 20x, and opens the arm portion 20x outdoors. After pushing out toward the head, a series of operations of moving to the tip side of the arm and attaching the evacuation device must be performed. Even in the event of an emergency such as a disaster, it is easy to get upset, and even with sufficient strength, it is difficult to reliably perform such complicated operations and may not be able to prepare for evacuation well. was there.

Here, in order to quickly prepare for evacuation, if the evacuation device is attached to the arm in advance, the weight of the evacuation device is added to the weight of the arm, and the push-out operation of the arm from the size of the weight. Is thought to be difficult. In this case, since the load corresponding to the evacuation device is applied only to one end of the arm, the arm is rattled, and it is difficult to push out the arm from the viewpoint of holding the arm. It is considered to be. Thus, when the evacuation device is attached to the arm portion in advance, there is a possibility that preparation for evacuation may be delayed.
That is, due to various problems as described above, there has been a demand for an evacuation apparatus mounting apparatus that can prepare for evacuation with a smaller force and with a simpler and fewer procedure such as a one-touch type.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an evacuation device mounting apparatus that can easily and quickly set from a stored state to a used state, and that can greatly improve handling.

A mounting device for an evacuation device according to the present invention includes a column provided facing a building space communicating with the outdoors, and a first posture along the standing direction of the column on the indoor side of the column on the upper end side of the column. And a second posture that crosses the standing direction of the support column, and an evacuation device that moves up and down along the outer wall portion of the building is provided on the outdoor side end of the arm portion. An apparatus for attaching an evacuation device attached to a part, comprising: a holding part that holds the arm part in the state of the second posture; and a delivery mechanism that sends out the arm part in the state of the second posture to the outdoor side. Yes and, when said outer pipe and the inner pipe are connected, the outer pipe is lower, the inner pipe is arranged above the feeding mechanism, with constant spring force in a direction feeding the arms A spring mechanism for biasing the arm Is mounted via a spring body constituting the spring mechanism in the interior pipe, said in a state where the outer pipe and the inner pipe are overlapped with each other, the first position the arms on the outer surface of the outer pipe It is characterized by including a lock member that is locked in the state described above.

According to the present invention, the arm portion is sent out to the outdoor side by the feed-out mechanism only by changing the posture of the arm portion in the state of the first posture to the second posture. At this time, the arm portion is sent out to the outdoor side while being held in the second posture by the holding portion.
That is, according to the present invention, it is possible to easily and quickly install the evacuation device mounting apparatus by a simple operation of changing the posture of the arm without placing a burden on the operator such as pushing the arm toward the outdoor side. Can be set to use. Thereby, the handleability of the attachment apparatus of an evacuation device can be improved significantly.
Further, according to the present invention, when the arm portion in the first posture along the standing direction of the support is gradually pulled away from the support toward the second posture by the operator, at a predetermined timing. The arm is lifted upward by the spring mechanism, and is sent out over the upper end of the column in the second posture. This is because the feeding is executed when the load on the arm portion gradually decreases with the change in the posture of the arm portion and the magnitude of the spring force of the spring mechanism exceeds the load on the arm portion. That is, according to the present invention, it is possible to set the evacuation device mounting apparatus to the use state more easily and quickly without placing the burden of lifting the arm portion upward on the operator.
Here, the setting of the spring force of the spring mechanism is appropriately determined according to the load of the arm portion (including the load of the evacuation device when the evacuation device is attached to the arm portion in advance). Is closer to the load of the arm portion in the first posture, the arm portion is sent out with a smaller posture change, and the force required for the operation can be reduced. Note that the arm portion can be maintained in the first posture by setting the magnitude of the spring force to be smaller than the load of the arm portion in the first posture.
Here, the arm is attached to the upper pipe of the outer pipe and the inner pipe when connected, and is locked to the lower pipe when connected by the lock member.
As for the lock member, for example, a structure in which the bracket is fixed to the side surface of the lower pipe at the time of connection and the bracket and the arm portion are locked by a pin can be employed.
In addition, what is called a coupling etc. can be employ | adopted as a support | pillar spring. When the coupling is employed, the spring body can be pivotally supported along the cross-sectional direction of the inner pipe by the shaft core portion, and the winding outer end of the strip spring body can be fixed to the outer pipe.
According to the present invention, by adopting the double pipe structure of the outer pipe and the inner pipe and the lock member, the inner pipe can be accommodated inside the outer pipe, the column can be made compact, and the mounting device is used. When doing so, the outer pipe and the inner pipe are connected up and down only by the release operation of the lock member by the biasing force of the support spring, so that it does not take time to handle.
Here, since the arm portion is locked by the lock member, the arm portion is not unintentionally sent to the outdoor side due to an inadvertent posture change of the arm portion, and one of the arm portions attached to the arm portion Since the pipe is locked to the other pipe via the arm portion, the pipe is not inadvertently extended. In this way, the lock member can be locked in an unusable state by restricting and releasing the restriction of both the extension of the outer pipe and the inner pipe and the posture change of the arm part by the lock member, Safety when not in use can be ensured, and handling can be further improved.

In this invention, it is preferable that the said holding | maintenance part was equipped with the plate-shaped lubrication member which slidably contacts the said arm part.
According to this invention, the arm portion is smoothly guided in the delivery direction along the surface of the plate-like lubricating member. Thereby, the attachment apparatus of an evacuation device can be set to a use state more quickly and reliably.
Here, as the lubricating member, an alloy plate using a solid lubricant can be employed. Further, regarding the arrangement of the lubricating member, it is possible to arrange the lubricating member directly on the support column, or to arrange the lubrication member via another member or the like that attaches the arm part to the support column.

In the present invention, the lubricating member is disposed in the vicinity of the upper end portion of the support column, and the holding portion is disposed at an opposed position on the indoor side of the lubricating member and sandwiching the lubricating member and the arm portion. It is preferable to have provided.
Here, as a rolling element, shaft-like members, such as a shaft and a bolt, etc. are employable, for example.

According to this invention, since the arm portion is guided in the feed-out direction by rolling of the rolling element, the arm portion can be sent out more quickly and reliably.
Further, according to the present invention, when the arm portion is sent out in a direction crossing the standing direction of the support column, first, the arm portion is inclined from the first posture to the standing direction of the support column. Thus, the rolling element serves as a bearing, and the lubricating member serves as a bearing in accordance with the change in the posture of the arm portion accompanying the delivery. Under the present circumstances, the arm part which became diagonal with respect to the support | pillar is hold | maintained by the rolling element provided in the indoor side, and the wobble of an arm part is prevented. Further, since the rolling element has a smaller contact area with the arm portion than the sliding bearing, there is no problem in guiding the arm portion even if the inclination of the arm portion with respect to the standing direction of the support column varies.
Here, the arm portion is lifted from the first posture and is sent out over the upper end portion substantially along the upper end portion of the support column. The posture of the arm portion is different, and it is preferable to provide a plate-like lubricating member as a bearing in the vicinity of the upper end portion of the support as the indoor bearing, as in the present invention. As a result, the arm portion is sufficiently brought into contact with the outdoor bearing and guided with good straightness, so that the variation in the posture of the arm portion can be allowed also in this respect. As described above, since it is possible to cope with variations in the posture of the arm portion, it is possible to improve the degree of freedom of design, and it becomes easy to assemble the arm portion, the support column, the holding portion, the feeding mechanism, and the like.
Therefore, it is possible to provide products having various configurations by changing the length and weight of the arm portion, the weight of the evacuation device attached to the arm portion, the shape of the arm portion and the support column, the configuration of the delivery mechanism, and the like.

In the present invention, the spring mechanism includes an axial core portion fixed to one of the support column and the arm portion, one end portion attached to the axial core portion, and the other end portion formed between the support column and the arm portion. It preferably has a strip spring body fixed to the other.
Here, in the spring mechanism, the spring main body of the strip is wound around the shaft core portion, and the arm portion is urged in the feeding direction by the winding force of the spring main body. As this spring mechanism, a so-called coupling or the like in which a strip steel is wound around the shaft core portion can be employed.

According to this invention, a constant load and a constant torque can be obtained by the spring mechanism configured as described above, so that there is an advantage that the feeding operation of the arm portion becomes even smoother. Furthermore, this spring has a configuration in which the spring body of the strip is wound, and the load design is easy and can be accommodated.

In this invention, the said arm part is equipped with the hanging tool which suspends the said evacuation device in the outdoor side edge part, and the said support | pillar has the said evacuation device lowered | hung to the said hanging device when the said arm part is in a 1st attitude | position. It is preferable that a holding unit for an evacuation device to be held is provided.
Here, as the evacuation device holding portion, for example, it is conceivable that a projection is formed on the side surface of the support column, and the evacuation device is placed on or hooked on the projection. In addition, when an evacuation device having a reel is used, a reel that is heavy and bulky is held by hooking the shaft core portion of the reel on a protrusion or the like, and the entire evacuation device is stably held. .

  According to this invention, since the evacuation device is held by the evacuation device holding portion, the attachment device and the evacuation device can be easily stored together with the evacuation device attached to the arm suspension beforehand. Can do. Thereby, it is not necessary to attach the evacuation device to the attachment device every time it is used, and the handleability of the attachment device or the evacuation device is further improved, and evacuation preparation can be performed more quickly.

[2. Usage of this embodiment]
The usage method of the attachment apparatus 1 by the above structure is demonstrated with reference to each figure in order of FIG. 3, FIG. 9, FIG.
First, as shown in FIG. 3, when the mounting device 1 is stored, the second-stage pipe 12 is accommodated in the frame pipe 11, and the arm portion 20 is in the first posture in the indoor side of the frame pipe 11. It is in the state of the 1st posture along the side. Here, a gentler 9 is attached to the hanging tool 211 in advance, and a reel 92 of the gentler 9 suspended from the hanging tool 211 is hung on a pair of steps 111 and held. In this state, the coupling member 15 is wound by the lock member 33 so that the second-stage pipe 12 does not jump out of the frame pipe 11 inadvertently, and in addition, the arm portion 20 is not sent out due to an inadvertent posture change. The attachment and the posture change of the arm portion 20 are restricted, and the attachment device 1 is in a locked state.

  And when evacuating from a building at the time of a disaster, etc., the lock of the attachment device 1 is released by an operation of pulling out the safety pin 332 of the lock member 33 so that it can be handled. Then, the second-stage pipe 12 is pushed up from the frame pipe 11 by the winding of the coupling 15, and the state shown in FIG. 9 is obtained. The pushed-up second-stage pipe 12 is locked by a stopper 13 while being connected to the upper side of the frame pipe 11. Then, the posture of the arm unit 20 can be changed.

Then, when the arm portion 20 in the first posture state is changed to the second posture state by placing a hand on the stopper 221 of the arm portion 20 from the state shown in FIG. ) To (C), the arm portion 20 is sent out to the outdoor side.
Specifically, when the operator changes the posture of the arm unit 20 to the state shown in FIG. 10A, the reel 92 of the slow descender 9 is removed from the step 111 and the winding of the coupling 50 is taken up at a predetermined timing. Since the force exceeds the weight of the arm portion 20, the operator does not apply force to the arm portion 20, and only the winding force of the coupling 50 is used as shown in FIGS. 10B and 10C. The portion 20 is automatically lifted horizontally and sent out outdoors. This is because the feeding of the arm 20 is executed when the load of the arm 20 gradually decreases with the posture change and the winding force by the coupling 50 exceeds the load of the arm 20. is there.
Here, the setting of the spring force of the coupling 50 is appropriately determined according to the weight of the arm portion 20 and the weight of the descender 9, and the magnitude of the spring force of the coupling 50 is the weight of the arm portion 20 in the first posture. The closer the position is, the smaller the posture change causes the arm 20 to be sent out, and the force required for the operation of the attachment device 1 can be reduced.

By the way, when the arm portion 20 is sent out, first, as shown in FIG. 10 (B), the arm portion 20 is in a posture that obliquely intersects the standing direction of the support column 10, and in this posture, the bolt 42 is It becomes a bearing of the arm part 20. The arm portion 20 is guided toward the upper end portion of the second-stage pipe 12 by the rolling of the bolts 42.
Then, as shown in FIG. 10C, when the arm portion 20 rides on the upper end portion of the support column 10 and assumes a substantially horizontal posture, the lubricating member 41 becomes the sliding bearing of the arm portion 20 and the arm portion 20 is now turned on. The bolt 42 is in sliding contact with the lower surface of the arm portion 20 and is in contact with the other upper surface of the arm portion 20 in rolling contact. Originally, the arm portion 20 is tilted by the load of the slow-down machine 9 attached to the tip portion 21, and the arm portion 20 is guided in a zigzag manner by the lubricating member 41 and the bolt 42. It is stable in an almost horizontal posture, and is sent smoothly to the indoor side. Then, the arm portion 20 is fed out until the arm stopper 221 is locked by the bolt 42, and the arm portion 20 and the support column 10 are substantially L-shaped as shown in FIG.
By the above, the attachment apparatus 1 is set to a use state and evacuation preparation is completed. Here, from the state in which the attachment device 1 can be handled by releasing the lock member 33, the operation necessary for setting the attachment device 1 in a state where the arm portion 20 extends to the outdoor side and completing the preparation for evacuation is as follows. There is only one operation for changing the posture of the arm 20 in the first posture to the second posture.
Furthermore, since the slow-down machine 9 is previously attached to the arm part 20, it can start evacuation rapidly. In addition, by attaching the safety belt 93 of the gentle descender 9 to the evacuee's waist, the refugee can descend along the outer wall portion of the building along the rope 91 and evacuate outside the building.

On the other hand, when the mounting device 1 is cleared, the following procedure is performed.
First, the arm stopper 221 is gripped, and the arm part 20 sent to the outdoor side is pulled back toward the indoor side. At this time, since the load of the arm portion 20 exceeds the winding force of the coupling 50 at a predetermined timing, contrary to the above, the arm portion 20 automatically hangs down in the order from FIG. 10 (C) to (A). As shown in FIG. 9, the arm portion 20 can be easily brought into the state of the first posture.
Next, when the stopper 13 is pulled, the connection between the second-stage pipe 12 and the frame pipe 11 is released. Therefore, the handle 32 is grasped and the second-stage pipe 12 is pushed down into the frame pipe 11, and the arm portion If the winding of the coupling 15 is restricted by inserting the safety pin 332 into the 20 locking holes 23, the mounting device 1 is in the retracted state shown in FIG. Usually, when the mounting apparatus 1 is not used, it is stored in a cover (not shown). Thus, the cleaning of the mounting device 1 is completed.

[3. Effects of this embodiment]
According to this embodiment as described above, the following effects are obtained.
(1) Since the feeding operation of the arm portion 20 is automated by the feeding by the coupling 50 and the holding by the holding portion 40, the operator is burdened with pushing the arm portion 20 into a state of extending outward. The mounting device 1 can be easily and quickly set to a use state by only one operation for changing the posture of the arm portion 20. Thereby, the handleability of the attachment apparatus 1 of an evacuation device can be improved significantly.

(2) Since the arm member is smoothly guided in the feed-out direction by the lubricating member 41, the attachment device 1 for the evacuation device can be set to the use state more quickly and reliably.

(3) Since the arm portion 20 is guided in the feeding direction by the rolling of the bolt 42, the feeding operation of the arm portion 20 can be performed more quickly and reliably.

(4) The lubrication member 41 and the bolt 42 for guiding the arm portion 20 are used, and the lubrication member 41 and the bolt 42 are arranged in a staggered manner, so that the arm portion 20 can be smoothly moved to the outdoor side. Sent out.
Specifically, when the arm portion 20 is fed obliquely with respect to the upright direction of the support column 10, first, the bolt 42 is a rolling bearing and the arm portion 20 is held. Can be prevented (see FIG. 10B). At this time, since the bolt 42 has a smaller contact area with the shaft than the sliding bearing, the arm portion 20 can be guided without any trouble even when the posture of the arm portion 20 varies. Subsequently, when the arm portion 20 rides on the upper end portion of the support column 10 and is sent out, the lubricating member 41 becomes a sliding bearing for the arm portion 20, and the arm portion 20 is smoothly sent out substantially horizontally along the lubricating member 41. (See FIG. 10C). If the rolling bearing with a small contact area with the shaft is adopted as the outdoor side bearing as in the indoor side, the bolt 42 and the rolling body are provided in a completely horizontal state, and the bolt 42 and the shaft Unless the shape members are provided in parallel to each other, the arm portion 20 is inclined according to a slight angle shift of the rolling elements and interferes with the upper end portion of the column 10 and the like. That is, the alignment of the bearing portion for ensuring the straightness of the arm portion 20 becomes severe. In response to such a problem, even when the arm portion 20 is held with a sufficient contact area by the plate-like lubricating member 41 and an assembly error including the bolt 42 occurs, the straightness of the arm portion 20 is maintained. The arm portion 20 can be smoothly fed out without being obstructed.
As described above, various products such as the length and weight of the arm portion 20, the weight of the slow down machine 9, the shape of the arm portion 20 and the column 10, and the configuration of the coupling 50 can be changed to provide various products.

(5) The coupling 50 is employed as a spring mechanism that sends out the arm portion 20, and the arm portion 20 is lifted upward by the winding of the coupling 50, so that the arm portion 20 is fed to the outdoor side, and thus the burden of lifting the arm portion 20 upward. Can be set to the use state even more easily and quickly.
Further, the coupling 50 provides a constant load and a constant torque, and since the initial load is large, there is an advantage that the feeding operation of the arm portion 20 becomes smoother. Furthermore, since the coupling 50 has a configuration in which the strip spring main body 52 is wound, the load design is easy and can be accommodated. Thereby, various products, such as the length of an arm part, a shape, and a weight, can be changed and various products can be provided.

(6) The support column 10 is constituted by a double pipe structure of the frame pipe 11 and the second-stage pipe 12, and the second-stage pipe 12 is accommodated in the frame pipe 11 by the lock member 33 while being accommodated in the second-stage pipe 12 The attachment device 1 is locked in an unusable state by engaging the attached arm portion 20 with the frame pipe 11 in the first posture. As a result, the column 10 can be made compact in general, and when the mounting device 1 is used, the frame pipe 11 and the second-stage pipe 12 are moved up and down only by pulling out the safety pin 332 of the lock member 33. It is easy to handle.

(7) Since the arm portion 20 is locked by the lock member 33, the arm portion 20 is not unintentionally sent to the outdoor side due to an inadvertent posture change, and the second-stage pipe 12 is inadvertently sent out. Will not rise. In this way, the lock member 33 regulates and cancels both the rise of the second-stage pipe 12 and the posture change of the arm portion 20, so that safety when not in use is ensured and handling is also possible. Is further improved.

(8) By providing the pipe 24, the pin portion 332A is held in a substantially horizontal posture, and a uniform force is applied to the entire pin portion 332A, so that the pin portion 332A is attached to the bracket 331 by the spring force of the coupling 15. The safety pin 332 can be easily pulled out with a small force without biting into the thick portions of the hole 331B and the locking hole 23 of the arm portion 20 at an angle.

(9) Since the reel 92 of the slow-down machine 9 lowered from the hanging tool 211 is held in step 111, the reel having a large weight is held in the slow-down machine 9, and the entire evacuation device is stable. Retained. Further, since the slow-down machine 9 is held by this step 111, it is easy to attach the slow-down machine 9 to the arm portion 20 in advance and store the attachment device 1 and the slow-down machine 9 together. Thereby, it is not necessary to attach to the attachment device 1 every time the slow down machine 9 is used, and the handleability of the attachment device 1 to the slow down machine 9 is further improved and evacuation preparation can be performed more quickly.

The present invention is not limited to the above-described embodiment, and includes modifications as described below.
In the above-described embodiment, the lowering device 9 is attached to the attachment device 1. However, the attachment device of the present invention is not limited to the lowering device, and various evacuation devices are attached to the arm portion. Can be used.
In addition, the attachment device may be installed not only in a room on the upper floor of a building but also on a balcony, a veranda, or the like. Here, when installing the mounting device, as in the above-described embodiment, it is also possible to use a bracket and a mounting base such as the base plate 70, or to the floor structure in the building room, the balcony, the basic structure of the veranda, etc. The support may be erected directly.
And since the evacuation device that can be moved up and down can be attached to the mounting device of the present invention, it is not limited to the case of evacuating from the upper floor of the building to the ground, or from the lower floor of the building to the ground part under the hill or under the cliff, or It can also be used when evacuating to the roof of an adjacent building.

  In the above-described embodiment, the frame pipe 11 includes the step 111 on which the reel 92 of the evacuation device 9 is hung. However, the shape of the evacuation device holding portion is not limited to the angle shape as in the step 111. Moreover, it can also be set as the structure which hold | maintains components other than the reel 92 in the slow-down machine 9, and the reel 92 may be directly placed on the floor etc. in this case.

The configuration of the support column, the arm unit, the feeding mechanism, the holding unit, and the like is not limited to the above embodiment. In the above-described embodiment, the specific shape, orientation, arrangement, and the like of the connection portion 30, the base plate 70, and the like can be changed as appropriate.
For example, the rolling element is not limited to the bolt 42 used in the above embodiment, and a sphere or a cylindrical member can also be used. Moreover, in the said embodiment, although the volt | bolt 42 was rotatably attached to the hole formed in the metal plate 31 with the washer 421 and the U nut 422, not only this but the volt | bolt 42 is fixed to the metal plate 31, and bolt A cylindrical body may be provided on the outer periphery of 42, and the arm portion 20 may be guided by the rotation of the cylindrical body. Furthermore, depending on various conditions such as the material of the bolt 42 and the load of the arm portion 20, the bolt 42 may be fixed to the metal plate 31 and the arm portion 20 may be guided along the cylindrical surface of the bolt 42. In addition, when the bolt 42 is a bolt with a head, the nut 422 should just be screwed by the edge part on the opposite side to the head of the bolt 42. FIG.
And in the said embodiment, the lubricating member 41 is provided in the outdoor side of the upper end part of the 2nd stage pipe 12, and it exists in the position which opposes the lubricating member 41 and the arm part 20 on the indoor side rather than this lubricating member 41. Although the bolt 42 is provided, the positional relationship between the lubricating member and the rolling elements is not limited to this. In short, the holding part may be configured to hold the arm part sent to the outdoor side.

And also about the holding | maintenance part, the arbitrary structures which can hold | maintain not only the lubrication member 41 and the volt | bolt 42 which were illustrated in the said embodiment but the arm part of a 2nd attitude | position can be employ | adopted. For example, it is conceivable to employ a lubricant using a synthetic lubricant such as dibasic acid ester or silicone oil, or a solid lubricant such as graphite, molybdenum disulfide, or talc. Further, if the rolling elements are made of the same material as that of the lubricating member, further smoothing can be achieved when the arm portion is delivered.
In addition, as long as it can hold | maintain the arm part sent out to the outdoor side, you may comprise a holding part, without providing a lubricating member and a rolling element. For example, as the holding member, it is also conceivable to employ a slide rail that is combined with rails and that can guide the arm portion linearly along the feeding direction.

Further, the configuration of the lock member and the configuration of the arm portion corresponding to the lock member are not limited to the above embodiment. In the embodiment, the pipe 24 through which the safety pin 332 is inserted is provided inside the arm portion 20, but in the modification of the present invention shown in FIG. 11, a pair of pipes 64 are provided on the outer peripheral side of the arm portion 20. Is provided. These pipes 64 are disposed at positions corresponding to the pair of holes 331B of the bracket 331, respectively, and guide and hold the safety pin 332 in a substantially horizontal posture, similar to the pipe 24 of the embodiment. It has become. In addition, both the pipe 24 of the said embodiment and the said pipe 64 may be provided, or you may provide the pipe which penetrates the arm part 20 inside and outside via the latching hole 23. FIG.
Further, in the above-described embodiment, the bracket 331 is fixed to the upper end portion of the frame pipe 11, but the position where the bracket 331 is provided is appropriately determined to be an easy-to-handle position such as an intermediate portion or a lower end portion of the frame pipe 11.

And as a structure of a locking member, like the said embodiment, in a double pipe structure, an arm part attached to the upper 2nd stage pipe 12 is latched by the lower frame pipe 11, and an arm is carried out. It is preferable to regulate both the posture change of the portion 20 and the extension of the double pipes 11 and 12, but as a reference technique according to the present invention, only one of the extension of the pipe and the posture change of the arm portion is used. It is also possible to adopt a configuration to regulate. When restricting the extension of the pipe, for example, in the above-described embodiment, a lever-type lock member that can rotate around the handle 32 is provided at a protruding portion of the handle 32 from the metal plate 31, and the rotation tip of the lever is provided. A configuration in which the portion engages with a recess formed on the side surface of the frame pipe 11 is conceivable.
