Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is used for evacuation devices installed on balconies of buildings, condominiums, general houses, etc., overhangs, and other floor surfaces, The present invention relates to improvement of a retractable evacuation device using a pair of telescopic type telescopic columns.

(Prior Art) Generally, an evacuation device using a pair of telescopic type telescopic columns includes, for example, Japanese Utility Model Publication No. 59-3119 and Japanese Utility Model Publication No.
The structure disclosed in Japanese Patent Publication No. 59-32719 is known.

That is, the evacuation device is a left and right telescopic column body formed by slidably inserting a plurality of column members made of metal pipes having different diameters in a telescopic manner, and between the telescopic column bodies along the longitudinal direction thereof. A plurality of horizontal pipes made of square pipes, which are fixed to the lower ends of the left and right column members facing each other at both ends, and foldable at both ends of each horizontal member and between the horizontal members. It is composed of link connecting materials.

Thus, the evacuation device has its base end rotatably mounted in a storage box installed on the floor, etc., and is stored in the storage box in a shortened state when not in use, and by its own weight when in use. It is designed to extend and descend, and become drooping.

Therefore, the evacuation device in the extended hanging state is prevented from swinging due to the expansion and contraction column body, and the evacuee can safely and smoothly evacuate through this.

(Problems to be solved by the invention) By the way, in the conventional evacuation equipment, since both end portions of each cross member are fixed to the outer peripheral surface of the lower end portion of each pillar member by welding, respectively When the both ends of the horizontal member are fixed to each other, the left and right pillar members may not be in a parallel state, or the distance between the left and right pillar members may not be a predetermined distance.

Therefore, when the horizontal members are fixed to the pillar members and then the respective pillar members are combined in a stretchable manner, the axis lines of the respective pillar members do not match and it is difficult or impossible to slidably fit them. There was a problem. In addition, even if each of the pillar members can be inserted and inserted, the axis of the assembled telescopic column may not be in a straight line. In this case, the telescopic column does not expand or contract smoothly, or during expansion or contraction. There was a risk that it would stop.

On the other hand, the axis line of the assembled expandable columnar body may not be straight even if the transverse members are fixed to each pillar member after the pillar members are elastically combined. Will occur.

As described above, in the conventional evacuation equipment, in order to facilitate the assembly of the expansion and contraction column body and to make the expansion and contraction smooth, it is necessary to accurately weld both before fixing the cross member to the column material. ,
There is a problem that extremely high processing accuracy is required.

If the clearance formed between the pillar and the pillar inserted into the pillar is increased, it is possible to easily combine the pillars and smoothly expand / contract the expandable / contractible pillar, which causes the problems described above. Can be resolved.

However, in this case, when the evacuee descends along the stretched column, the stretched column is largely bent in the front-back direction due to the large clearance provided between the adjacent column members. A new problem arises in that an evacuee falls off a horizontal member and falls, or the telescopic column flexes greatly in the front-rear direction, causing anxiety and making it difficult to descend properly.

As a result, the actual situation is that the clearance between adjacent column members cannot be increased more than necessary.

The present invention was devised in order to solve the above problems, and its purpose is to make it possible to easily and easily assemble without requiring high processing accuracy, and to perform expansion and contraction very smoothly. To provide the equipment.

(Means for Solving the Problems) The invention according to claim 1 is a left and right telescopic columnar body formed by telescopically inserting a plurality of columnar materials having different diameters, and lower end portions of the respective columnar materials. A pipe-shaped mounting portion fixedly attached to each other, and a horizontal member disposed between the left and right expandable columnar bodies at regular intervals along the longitudinal direction thereof, and both ends of which are loosely fitted in the mounting portion. , A foldable connecting member disposed at both end positions of each horizontal member and between each horizontal member, and an end portion of each horizontal member, an end portion of each connecting member, and a front-back direction formed in each mounting portion, respectively. And a support shaft that is inserted into the through hole in a loose fit state and is prevented from coming off from the through hole to connect the respective members.

According to a second aspect of the present invention, a left and right expandable columnar body formed by telescopically inserting a plurality of columnar materials having different diameters, and an annular body slidably fitted in each columnar material. , A pipe-shaped mounting portion fixed to the lower end portion of each column member and each annular body, and arranged at regular intervals along the longitudinal direction between the left and right telescopic column bodies, and both end members serve as mounting portions. A plurality of transverse members inserted in a loose fit state, a foldable connecting member disposed at both end positions of each transverse member and between each transverse member, an end portion of each transverse member, an end of each connecting member And a supporting shaft that is loosely fitted and inserted into through holes in the front-rear direction that are formed in the mounting portion and each mounting portion, and that is prevented from coming off from the through holes to connect the respective members.

(Operation) In the evacuation equipment, the pillars are slidably inserted, and the ends of the transverse members and the ends of the connecting members are loosely fitted to the lower ends of the pillars by the longitudinal support shafts. By pivoting into a state,
Each pillar is slidably inserted, and every other horizontal member is attached to each pillar so as to be movable along it, and the end of each remaining horizontal member and the end of each connecting member. Are rotatably connected to the ends of the respective pillars by means of support shafts in the front-rear direction so as to be assembled.

Since the evacuation equipment is provided with clearances between adjacent pillar members and each supporting shaft portion, each pillar member can move a little relative to each cross member. As a result, even if the processing accuracy is low, the respective pillar members can be easily and easily fitted and the telescopic pillar body can be assembled very easily.

Further, the evacuation device expands and contracts extremely smoothly due to the clearances provided between the adjacent pillar members and each supporting shaft portion.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

1 to 4 show an evacuation device according to the invention as defined in claim 1, wherein the evacuation device comprises a pair of telescopic columns 1, a plurality of lateral members 2, a plurality of connecting members 3 and a plurality of supports. It is composed of a shaft 4 and the like.

The expandable columnar body 1 is formed by connecting and combining a plurality of rigid columnar members 5 so as to be expandable and contractible, and is configured to extend downward in a straight line by its own weight.

In the present embodiment, the expandable columnar body 1 is made by forming each column member 5 with circular metal pipes having different diameters, and slidably inserting and inserting these column members 5 into adjacent column members 5 at the time of extension. It is configured so that part of it does not polymerize and bend.

Further, each column member 5 is provided with a square tubular mounting portion 5'on the outer peripheral surface of the lower end portion except for the column member 5 having the maximum diameter, and the mounting portion 5'is made of a square pipe. It is integrally fixed to the outer peripheral surface of the lower end portion of the material 5 by welding.

Then, the pair of telescopic columns 1 are attached to each of the column members 5 by the attachment portions 5 '.
In the state where they face each other, the upper end members, that is, the column members 5 having the largest diameter are connected by the connecting member 6.

Incidentally, the mounting portions 5'of the respective pillar members 5 are sequentially lengthened downward as the intervals between the left and right mounting portions 5'become the same.

In addition, a slight amount of clearance is provided between the adjacent column members 5.

The horizontal members 2 are arranged in the same number as the number of the pillar members 5 along the longitudinal direction of the expansion and contraction pillar body 1, and the left and right facing pillar members 5 are opposed to each other.
Are connected.

In this embodiment, each cross member 2 is made of a metal square pipe having the same length, and both ends of the cross member 2 are attached to the column member 5 by the attachment portions 5 '.
It is structured such that it is loosely fitted and is fitted in, and only the uppermost horizontal member 2 has both ends thereof fixed to the outer peripheral surface of the lower end portion of the pillar member 5 having the maximum diameter by welding.

The connecting members 3 are disposed at both end positions of each horizontal member 2 and between each horizontal member 2, and connect the respective horizontal members 2 with each other, and when the expandable column 1 is in the extended state. It serves as a stopper for preventing the pillar member 5 from coming off in the longitudinal direction.

In this embodiment, each connecting member 3 is composed of a pair of link members 3 ', and the end portions of the link members 3'have rivets 7.
It is pivotally connected by etc. and is configured to be freely foldable.

In addition, a coil spring (not shown) that folds and urges each link member 3'to rotate toward the center side of the evacuation equipment is interposed at the pivotal point, that is, the rivet portion of each connecting member 3, and extends. The respective connecting members 3 are automatically folded in order when the expandable columnar body 1 in the state is shortened. The urging force of this coil spring is set so that each connecting member 3 becomes a straight line when the expandable columnar body 1 is extended.

In addition, the length of each connecting member 3 is set such that each pillar member 5 of the expandable pillar member 1 which is in an expanded state when it is interposed between the horizontal members 2 does not come off in the longitudinal direction. .

The support shaft 4 pivotally connects the ends of the cross members 2 and the ends of the connecting members 3 to the mounting portions 5 ′ of the pillar members 5 in a loosely fitted state.

In this embodiment, a rivet is used for the support shaft 4, which is formed before and after being drilled at the end of each connecting member 3, each end of each cross member 2 and each mounting part 5 '. It is inserted into the through hole in the direction, and the washer 8 is fitted in and the end portion is caulked to prevent it from coming off.

The outer diameter of the support shaft 4 is set to be slightly smaller than the inner diameter of each through hole so that a clearance can be formed around the support shaft 4.

Thus, in the evacuation equipment, the pillar members 5 are slidably inserted, and the end portions of the horizontal members 2 are inserted into the attachment portions 5'of the pillar members 5,
The end portion of the connecting member 3 is superposed on the end portion of the cross member 2,
After the support shaft 4 is inserted through the through holes formed in the cross member 2 and the mounting portion 5 ', the support shaft 4 is fitted with a washer 8 and the ends thereof are caulked to assemble.

The evacuation device has its base end, that is, the upper end of the telescopic column 1 is rotatably mounted in a storage box (not shown) installed on the floor of the building, etc., and is horizontal and shortened when not in use. It is housed in the storage box in a state and is rotated from a horizontal state to a vertical state when used.

The evacuation equipment connecting body 6 includes a slow-moving machine (not shown) for slowing down the evacuation equipment's extension / falling speed and a winder (not shown) for shortening the extended evacuation equipment. They are provided, and these are configured in the same manner as conventionally known ones. Further, in the evacuation equipment, since the horizontal members 2 and the connecting members 3 are located between the left and right expandable columnar bodies 1, the thickness of the evacuation equipment itself is thin and it is easy to store it in the storage box.

During an emergency evacuation such as a fire, when the evacuee lowers the evacuation equipment in the storage box in a vertical state, the evacuation equipment gradually expands and descends due to its own weight, and becomes a drooping state as shown in FIG. At this time, the evacuation equipment can be stretched well without being subjected to an impact load or the like because the extension descending speed is moderated by the slow-moving machine. Further, since the evacuation equipment has clearances provided between the adjacent pillar members 5 and in each of the support shafts 4, the evacuation equipment can be extended extremely smoothly.

Then, when the evacuation equipment is in the extended state, the evacuee evacuates along with this. In addition, since a clearance is provided in each of the support shafts 4, the horizontal member 2 is slightly loosened.
When the load of the evacuees is applied, the cross member 2 is pressed downward and fixed. As a result, the evacuees can safely and smoothly descend even if the support shafts 4 are provided with clearances.

On the other hand, after use, the stretched evacuation device is shortened by the winder. At this time, the connecting members 3 are sequentially and orderly folded by the coil spring.

FIG. 5 and FIG. 6 show an evacuation device according to the invention described in claim 2, in which every other horizontal member 2 is movably mounted along each pillar member 5 along with the rest. Each horizontal member 2
And the end portions of the respective connecting members 3 are pivotally connected to the end portions of the respective pillar members 5 by a support shaft 4 in the front-rear direction in a loosely fitted state.

That is, in this evacuation device, an annular body 9 having an attaching portion 9'is slidably inserted into each pillar member 5, and the end portion of each transverse member 2 is attached to the attaching portion 9 of the annular body 9. ′, And the end portion of the cross member 2 and the end portion of the connecting member 3 superposed thereon are pivotally connected to the mounting portion 9 ′ of the annular body 9 by the support shaft 4 in the front-rear direction in a loosely fitted state. In addition, the remaining horizontal members 2 together with the connecting members 3 are pivotally connected to the mounting portions 5'of the respective pillar members 5 by the support shafts 4 in a loosely fitted state in the same manner as in the above embodiment.

By doing so, the length of each pillar 5 can be made longer than that of the above-mentioned embodiment, and even if the total length of the evacuation equipment becomes long, the diameter of the pillar 5 at the bottom end becomes extremely small. The elastic columnar body 1 is not weakened in strength.

Although a circular pipe is used as the pillar member 5 in each of the above embodiments, a square pipe or a C-shaped channel member may be used.

In each of the above-mentioned embodiments, a square pipe is used as the cross member 2, but a solid square member, a solid round bar, a circular pipe or the like may be used.

In each of the above embodiments, the connecting member 3 is formed by connecting a pair of link members 3 ', but a wire or a chain may be used.

In each of the above embodiments, the uppermost cross member 2 is fixed to the pillar member 5 by welding, but the uppermost cross member 2 is also pivotally connected to the pillar member 5 by the support shaft 4 in a loosely fitted state. It may be done.

In each of the above embodiments, the end of the cross member 2 is fitted onto the mounting member 5'of the pillar member 5, but the end of the cross member 2 is fitted into the mounting portion 5 '. May be.

In each of the above-described embodiments, the coil spring is interposed at the pivot point of the connecting member 3 so that the connecting member 3 is folded and urged in the same direction. However, the coil spring is interposed in the supporting shaft 4 portion. Alternatively, the connecting member 3 may be folded in the same direction and biased.

In each of the above-mentioned embodiments, a rivet is used for the support shaft 4, but a bolt may be used for the support shaft 4 and a nut may be used to prevent the support shaft from coming off.

(Effects of the Invention) As described above, the evacuation device according to claim 1 has an end portion of each pillar member of the expandable columnar body formed by elastically connecting and combining a plurality of pillar members, an end portion of a transverse member, and a connecting member. Since the end portions of the support rods are pivotally connected by a support shaft in the front-rear direction in a loosely fitted state, a clearance is provided between adjacent column members of the expandable columnar body and each support shaft portion. As a result, the evacuation equipment according to claim 1 does not need to accurately fix the pillar material and the lateral material when fixing the pillar material and the horizontal material like the conventional evacuation equipment, and each of the pillar materials is simple and easy. Can be easily combined. That is, the evacuation device can be easily and easily assembled without requiring high processing accuracy.

In addition, since the evacuation equipment has clearances between adjacent pillars and the supporting shaft, it may be said that it does not expand or contract smoothly like conventional evacuation equipment, or it stops during expansion or contraction. Instead, it expands and contracts extremely smoothly and smoothly.

Of course, a pipe-shaped mounting part is fixed to the lower end of each pillar,
Since the horizontal member is inserted into the mounting portion in a loosely fitted state, even if there is some error in the length of each horizontal member, the horizontal member and the mounting portion can be opposed to each other by changing the fitting depth. The space between the left and right column members can be set to a predetermined space.
As a result, the axis of the telescopic column becomes a straight line so that the telescopic column can be smoothly expanded and contracted, and the assembly can be performed more easily and easily.

The evacuation device according to claim 2 has the following effects in addition to the above effects.

That is, every other horizontal member is movably attached to each column member along the same, and the end portions of the remaining horizontal members and the end portions of the connecting member are supported in the front-back direction to the end portions of each column member. Since the shaft is pivotally connected in a loosely fitted state, the length of each pillar can be increased. As a result, even if the total length of the evacuation equipment becomes long, the diameter of the bottommost column member does not become extremely thin, and the telescopic column body does not weaken in strength.
