  The present invention relates to a scaffold device, and more particularly to an improvement of a scaffold device that enables movement while being folded.

  For example, as a scaffold device suitable for use as a workbench, there have been various proposals, and among them, Patent Document 1 discloses a proposal of a scaffold device that can be folded and moved. .

  That is, the scaffold device disclosed in Patent Document 1 has an upper handrail frame portion, a middle scaffold plate support portion, and a lower caster portion that are detachable from each other, and in particular, a middle scaffold plate support. The part is provided with a hinge at the center in the longitudinal direction and can be folded into a planar M-shape.

Therefore, according to this scaffold device, by folding the scaffold plate support part with the upper handrail frame part removed from the middle scaffold plate support part, the so-called compactness can be achieved. It is possible to transfer to a desired position by using a caster under the above condition.
Japanese Examined Patent Publication No. 7-73829 (see claims, paragraphs 0021 and 0022, FIGS. 1 and 3)

  However, the proposal disclosed in Patent Document 1 described above is not basically problematic in that it can be folded and moved by using a caster. It may be pointed out that there is a slight disadvantage.

  That is, in the scaffold device disclosed in Patent Document 1 described above, the middle-stage scaffold plate support portion is folded into a planar M shape by a hinge portion provided at the center portion in the longitudinal direction. Is configured such that a U-shaped pin rotatably attached to the rotation hole is detachably attached to the fixed groove.

  The rotation hole is opened in a semi-circular plate-like body formed by alternately combining two stages, and a bending reed forming a scaffolding plate support is connected to the plate-like body.

  On the other hand, in the above-described hinge, the U-shaped pin having a spring and a stop portion is inserted into a rotation hole opened in a plate-like body formed in a semicircular and two-stage staggered combination, In addition, the plate-like body is also formed with a fixed groove for inserting the U-shaped pin, so to speak, the tip side. Therefore, when this hinge is viewed as a component, it becomes a complicated structure and the product is reduced in cost. There is a problem that it is impossible to expect a reduction in cost, and therefore it is impossible to expect an improvement in versatility due to a reduction in product cost.

  The present invention was devised in view of such a current situation, and the object of the present invention is to enable the product to be folded and transportable, as well as to reduce the product cost. It is an object of the present invention to provide a scaffold device that is optimal for expecting improvement in its versatility.

In order to achieve the above-described object, the structure of the present invention is formed by forming four vertical struts arranged at four corners forming a rectangular plane, and a left side surface and a right side surface that are continuous surfaces of the rectangular plane. a plurality of transverse connecting member and said left side and a right side are the above longitudinal struts forming the left side and a right side that is coupled with a proper interval in the vertical direction to each pair of the longitudinal struts Yes in base end scaffold made and a folded body which is pivotally connected, the folded body is a distance in the vertical direction to the longitudinal struts of the left to the right and left vertical posts forming the front continuing to And a left socket made up of a pair of pipe bodies interposed in a freely rotatable manner, and a right side made up of a pair of pipe bodies inserted in a turnable manner with a space in the vertical direction on the right vertical column. And the base end is connected to the left socket. That Hidarikatatai and has a right body proximal to the right of the socket are connected, and a hinged portion connecting together the front end of the left body and the right body, the hinged portion is the It has a core body that extends in the vertical direction along the vertical support column, and a socket for a hinge that is a pipe body that allows the core body to be rotatably inserted inward, and the upper and lower ends of the core body have the above- mentioned one of the upper and lower tip of the left body or the right body is connected respectively, the other of the left body or the right body socket for arrangement of the hinge between the upper and lower ends of the core The upper and lower ends of each of the upper and lower ends of the core body are connected to each other, and the height position of the upper end portion of the core body is the same height position as the interposition position of the upper socket in the left socket and the right socket to the vertical column, The socket on the left side of the vertical strut is the height position of the lower end of the core And is an upper become height than interposed position of the lower side of the socket in the right side of the socket, have a scaffolding plate spanned to the lateral connecting member in the left side and a right side, the lower end of the vertical struts It is assumed that a caster is provided in

  Therefore, in the scaffold device according to the present invention, it is necessary to remove the scaffold plate, but the scaffold device having an inner space having four vertical columns and having a rectangular planar shape is folded by folding the folding body. It becomes compact in the state which piled up, and the transfer using a caster is attained.

At this time, a hinge coupling portion that enables folding of the folding body composed of the left and right side bodies extends in the vertical direction along the vertical support column, and the core body is rotatable inward. It consists of a socket for a hinge comprising a pipe to be inserted, whereas one of the upper and lower tip of Hidarikatatai or right body is connected respectively to the upper and lower ends of the core, upper and lower core Since the upper and lower ends of either the left body or the right body are respectively connected to the hinge socket disposed between the end portions, the above-mentioned Patent Document 1 describes the parts configuration. Compared to the disclosed hinge, the configuration is simple, and therefore, the product cost can be reduced by reducing the component cost.

In addition, in the hinge disclosed in Patent Document 1 described above, when the scaffold plate support portion is folded into an M shape in a plan view, a plate-like body that forms a hinge between two folded recumbent ribs is provided. ready to be sandwiched, correspondingly, but will be bulky hinge portion is exposed, the hinged connection of the present invention, a socket for longitudinal consists pipe in a core body which is extended in the hinge Furthermore, the height position of the upper end portion of the core body is the same height position as the interposed position of the upper socket in the left socket and the right socket to the vertical column, and the core since the height position of the lower end portion of the body Ru is the height position where the above the interposed position of the lower side of the socket at the left side of the socket and the right of the socket in the vertical strut, the table bulky within the hinged connection It will not be issued.

  As a result, in the scaffold device according to the present invention, the product cost can be reduced by reducing the component cost, and it is optimal for expecting the improvement of the versatility.

Hereinafter, the present invention will be described based on the illustrated embodiment. As shown in FIGS. 1, 2, and 3, the scaffold device according to the present invention is disposed at four corners forming a rectangular plane. That is, it has four vertical struts 1 arranged so as to form a space in which the planar shape is rectangular (see FIG. 2), and as represented by the right side shown in FIG. Each pair of vertical struts 1 that respectively form the right side surfaces are integrally connected by a plurality of horizontal connecting members 2 that are arranged at an appropriate interval in the vertical direction.

  And in this scaffold apparatus, the vertical support | pillar 1 which forms the left side surface and the right side surface is connected with the folding body 3 arrange | positioned in this front, making it the left and right vertical support | pillar 1 which forms a front surface and a back surface. (See FIG. 1).

  In addition, this scaffold device has a scaffold plate 4 that is bridged over the horizontal connecting material 2 on the left side surface and the right side surface, and has a caster 5 at the lower end of each vertical column 1. (See FIG. 1 and FIG. 3).

  Therefore, in this scaffold device, when looking at the state of use, the front and left and right side surfaces are so-called partitioned, and the back surface is open, so that it exhibits a box-like planar shape without a lid. An operator on the board 4 can practice various operations on, for example, a wall surface of a building through the open back surface.

In this scaffold device, the scaffold plate 4 needs to be removed when moving when not in use, but as shown in FIG. 4, the folding body 3 is folded in a W shape in plan view. By overlapping the left and right side surfaces in such a manner, folding becomes possible, that is, so-called compaction is possible, enabling transfer in this compacted state, and under this compacted state Therefore, the movement using the caster 5 can be performed.

  Under the premise as described above, first, the vertical column 1 is basically composed of a so-called single tube, and is connected to the folding body 3 and the handrail body 6 described later, and further, It is said that it can be connected continuously.

  Next, the left and right side surfaces formed by the pair of vertical struts 1 and the horizontal connecting members 2, that is, the side surfaces, in other words, the side connecting members 2 are arranged in the vertical direction. It is assumed that they are formed in a so-called ladder shape (see FIG. 3).

  In this way, a plurality of lateral connecting members 2 are formed and the left and right side surfaces are formed in a ladder shape, so that the so-called mechanical strength on the left and right side surfaces can be ensured, and the installation position of the scaffold plate 4 to be described later That is, the construction height can be freely selected, and the usage scene of the scaffold device is increased.

Folding body 3, where shown, as shown in FIG. 1, and comprising a right body 31 that is left body 30 and the other being the one which is formed in a so-called pipeline structure, the left Each of the left and right sockets 30a and 30b has left sockets 30a and 30b and right sockets 31a and 31b. The sockets 30a and 31b are pipes connected to upper and lower base ends of the rectangular parallelepiped 30 and the right rectangular parallelepiped 31, respectively. , 30b, 31a, 31b are respectively interposed in the vertical support column 1, that is, pivotally attached.

And in this folding body 3, each front-end | tip in the left side body 30 and the right side body 31 is connected with the hinge coupling | bond part 32 , and this hinge coupling | bond part 32 is shown in FIG. As shown in FIG. 5, it is assumed that a core body 32 a extending in the vertical direction along the vertical support column 1 and a hinge socket 32 b made of a pipe body through which the core body 32 a is inserted are provided. Yes.

At this time, the hinge socket 32b is formed to be longer than the left sockets 30a and 30b and the right sockets 31a and 31b as shown in the drawing, but instead, Although not shown, it goes without saying that the upper and lower two parts having substantially the same length may be used.

Incidentally, as shown, when the socket 32b of the hinge interposed core 32a is made of a long pipe of one is the so-called integrity against the tip of the hinge coupling portion 32 of the right body 31 It is advantageous in ensuring.

And also, in the the folded body 3, whereas the upper and lower tip of the left body 30 being are connected respectively to the upper and lower ends of the core body 32a for forming the hinge coupling portion 32, the right is the other upper and lower tip of the rectangular parallelepiped 31 are to be respectively connected to a socket 32b of the hinge which is provided to be sandwiched socket 32b forming the hinge coupling portion 32, i.e., the upper and lower ends of the core body 32a.

At this time, the upper socket 30a of the left sockets 30a and 30b and the upper socket 31a of the right sockets 31a and 31b are connected to the vertical struts 1 at the same height position, that is, It ’s going to be pivoted.

On the other hand, the height position at which the upper end of the left body 30 is connected to the upper end of the core body 32a is the same height position as the position of the upper socket 30a. However, the connecting height position to the hinge socket 32b at the tip of the right side body 31 which is the other is lower than the upper end portion of the core body 32a, that is, the arrangement of the upper socket 31a . The height position is lower than the installation position.

The socket 30b connected to the base end on the lower side of the left body 30 and the socket 31b connected to the base end on the lower side of the right body 31 are so-called the same height position with respect to the respective vertical struts 1. in Although a pivotally mounted comprising the lower end position in the core body 32a of the lower side of the distal end of Hidarikatatai 30 are connected, the lower side of the socket 30b, is the above the arrangement position of 31b, right The connecting position of the lower end of the body 31 with respect to the hinge socket 32b is a height position above the position where the lower end of the left body 30 is connected to the lower end of the core body 32a. It is said.

  Therefore, in the folding body 3 according to the present invention described above, when the folding body 3 is folded, that is, as shown in FIG. 4, the left side body 30 and the right side body 31 centering on the hinge coupling portion 32. When compared with the proposal disclosed in Patent Document 1, the left body 30 and the right body 31 are not in an attitude of sandwiching the hinge coupling portion 32, and therefore, the mischievous volume is increased. It becomes possible not to express tension.

In addition, in the folding body 3 according to the present invention, a hinge body 32a in which the hinge coupling portion 32 extends in the vertical direction, and a hinge socket 32b comprising a pipe body through which the core body 32a is inserted. consists of a, relative to the distal end of the left body 30 to form a folded body 3 on the lower end portion of the core body 32a are connected respectively, the right to a socket 32b of the hinge in between the upper and lower ends Since the tips of the bodies 31 are connected to each other, when looking at the configuration, the configuration is simpler than the hinge disclosed in Patent Document 1 described above, and therefore the product cost is reduced by reducing the component cost. It can be expected to be cheap.

  Next, in the scaffold device of the present invention, the scaffold plate 4 is constructed, and it is said that the scaffold device is detachably constructed, but this is not only a scaffold but also a work table. This is a natural result in view of the fact that it is also used.

  That is, it is natural that a scaffold device of the kind of type has the scaffold plate 4. At that time, only one preset position, that is, as disclosed in, for example, Patent Document 1, the scaffold plate is used. If it is constructed only at a certain height position that is the upper end position of the vertical strut 1, the use range of the scaffold device is narrowed.

  On the other hand, in the present invention, since the scaffolding plate 4 is spanned over the horizontal connecting material 2 on the left side surface and the right side surface, the horizontal connecting material 2 is, as described above, the left side surface and the right side surface. , It is possible to construct the scaffolding plate 4 between the horizontal connecting members 2 at the same level, and as a result, the range of use of this scaffolding device. Will be widened.

  By the way, in the scaffold device of the present invention, the scaffold plate 4 is detachably connected to the lateral connecting material 2 forming the left and right side surfaces. May choose a free configuration.

  In the present invention, when the scaffolding plate 4 is placed on the horizontal connecting member 2, that is, when it is laid, it is laterally placed in the recess 4a (see FIGS. 6 and 7) formed at the end of the scaffolding plate 4. The connecting material 2 is fitted, and the movement of the scaffold plate 4 in the axial direction is prevented.

  Therefore, the scaffold plate 4 placed on the horizontal connecting member 2 may have a so-called stopper mechanism that prevents this from jumping up, that is, floating from the horizontal connecting member 2. It can be chosen freely.

  As the stopper mechanism, for example, as shown in FIG. 6, the stopper mechanism has a slide pin 42 that is maintained in a forward state by the urging force of the coil spring 41 and squeezes the lateral connecting material 2 between the bottom surface of the scaffold plate 4. In addition, as shown in FIG. 7, when the slide plate 44 held by the holder 43 connected to the inner side surface of the scaffolding plate is maintained in the advanced state, the lateral tie 2 is connected to the scaffolding plate 4. It is going to be sandwiched between them.

  Furthermore, in the scaffold device of the present invention, the caster 5 is provided at the lower end of each vertical column 1 that forms the left and right side surfaces and the front surface. As described above, the caster 5 is used. The transport when not in use is made possible.

  By the way, in the scaffold device of the present invention, the caster 5 is provided. In short, it is sufficient if the scaffold device can be transported when not in use. Therefore, from this viewpoint, the caster 5 is sufficient. Of course, 5 may be detachably attached to the lower end of the vertical column 1.

  Further, even if the caster 5 is fixed to the lower end of the vertical column 1 so as to be detachable, for example, although not shown, the caster 5 is formed in a flip-up manner, and when the scaffold device is fixed at a predetermined position, It is good also as a structure which bounces up 5 and does not get involved.

  On the other hand, in the scaffold device of the present invention, in addition to the above, the vertical column 1 enables the handrail body 6 and the outrigger structure 7 to be connected as described above. Hereinafter, the handrail body 6 and the outrigger structure 7 will be described briefly.

  First, the handrail body 6 is shown in the figure, and is assumed to be detachably connected so as to be bridged over the upper end portions of the left and right vertical struts 1 forming the front and back surfaces.

  Then, as shown in FIG. 8, the handrail body 6 has a distal end portion pivotally attached to either one of the left and right end portions, that is, the right end portion as shown in FIG. Although not shown in the figure, the housing 61 has a laterally U-shaped housing 61 that can be connected to the opposite handrail body 6, and this housing 61 is shown in FIG. When folded as indicated by the curved arrow in (A), it is assumed that it is housed in the plane of the handrail body 6 as shown in FIG. 8 (B).

  Incidentally, the housing 61 functions not only as a handrail, but also functions as a fence for preventing the operator from falling on the scaffolding plate 4. By being provided on the rear surface side, and by connecting the housing 61 in the opposite handrail body 6 to the handrail body 6, a so-called enclosed safe work space is formed.

  In view of the above, the casing 61 in the handrail body 6 is formed in a loop shape having a substantially rectangular front shape, although not shown, instead of being formed in the above-described laterally U shape. In this case, the self-supporting property of the casing 61 can be improved.

  Next, as shown in FIGS. 1, 2 and 3, the outrigger structure 7 is fixedly provided at the lower end of each pair of vertical struts 1 forming the left and right side surfaces. It is said that it is provided in order to ensure the stability at the time of installation, that is, in use.

  Therefore, in the outrigger structure 7, as shown in the figure, the front side which is the left side in the figure as shown in FIG. 3 while being integrally connected to the lower ends of the vertical struts 1 as a pair. And a wide leg 71 that holds the caster 5 at the lower end and extends to the back side, which is the right side in the figure, and an outrigger 72 that is held by the wide leg 71.

  The casters 5 themselves are formed in the same manner as described above, that is, formed so as to enable transfer of the scaffold device when not in use. It is assumed that the so-called ground contact width at the lower ends of the left and right side surfaces is increased to improve the independence of the left and right side surfaces.

  On the other hand, as shown in FIG. 9B, the outrigger 72 is formed so that the front shape is substantially L-shaped, and is held rotatably by the widening leg 71 via the bracket 73. At this time, the portion interposed in the bracket 73 has a recess 72a as shown in FIG. 9C, and the tip of the butterfly bolt 73a screwed to the bracket 73 is introduced into the recess 72a. It is assumed that when the outrigger 72 is fixed, so-called fixing is realized.

  In the outrigger 72, when the butterfly bolt 73a is loosened and extracted from the recess 72a, the outrigger 72 can be rotated in the horizontal direction while being held by the bracket 73. Thus, for example, as shown by arrows in FIG. 4, so-called folding can be performed along the left and right side surfaces.

  Therefore, in the scaffold device of the present invention formed as described above, when used, an operator can enter the scaffold plate 4 and can perform various operations. The handrail body 6 is continuously provided at the upper end portion of 1 and the safety of the worker is positively secured. The outrigger structure 7 is continuously provided at the lower end portion of the vertical column 1 and is installed at a predetermined position. The stability of the scaffold device is positively ensured.

  In this scaffold device, the folding device 3 is provided, and the folding device 3 can be folded to make the scaffold device compact. On the other hand, when the folding device 3 is used, In order not to be folded inadvertently, and to ensure the safety of workers entering the scaffolding plate 4, for example, as shown in FIGS. The vertical struts 1 are connected by braces 14 that are detachably disposed on the surface.

  By the way, this brace 14 is in this scaffolding device, and when the scaffolding plate 4 is installed on the horizontal connecting member 2, it is not necessary to worry about the folding of the scaffolding device. Of course, the arrangement of 14 may be omitted.

  In addition, in the scaffold device of the present invention, the movement by using the casters 5 in a so-called compacted state by folding the folding body 3 after the scaffold plate 4 is removed after movement when not in use. Will be possible.

  Incidentally, in the scaffold device of the present invention, depending on the so-called floor surface where the scaffold device is installed or the space where the scaffold device is installed, the scaffold device is not folded. Of course, the caster 5 may be used for movement in a so-called assembled state in which the scaffold plate 4 is not removed.

  By the way, in the scaffold apparatus of this invention, while implementing in the above-mentioned form, it can implement also in the form shown in FIG. 10 and FIG. 11, Therefore This is demonstrated below.

  That is, in the embodiment shown in FIGS. 10 and 11, the extension frame 8 shown in FIG. 12 is used. The extension frame 8 is connected to the upper end portion of the vertical column 1 so that the lower end portion is separable. As shown in FIG. 12 (A), the four vertical members 11 that form a space in which the planar shape is rectangular are formed inside.

  And this vertical member 11 shall be fundamentally comprised similarly to the above-mentioned vertical support | pillar 1, Therefore, in this extension frame 8, as shown in FIG.12 (C). And the horizontal connecting member 12 configured in the same manner as the horizontal connecting member 2 described above, and the folding member 13 configured in the same manner as the above-described folding member 3 as shown in FIG. It is supposed to become.

  That is, in this extension frame 8, a pair of vertical members 11 that respectively form the left side surface and the right side surface are integrally formed by a plurality of horizontal connecting members 12 arranged at appropriate intervals in the vertical direction. The vertical members 11 forming the left side surface and the right side surface are connected to the left and right vertical members 11 forming the front surface by the folding members 13 arranged on the front surface, and if necessary, the back surface is formed. The left and right vertical members 11 are connected by a brace 14 (see FIGS. 10 and 11).

The folding body 13 includes a left side body 130 and a right side body 131 which are formed in a so-called pipe structure. The left side body 130 and the right side body 131 are The left sockets 130a and 130b and the right sockets 131a and 131b made of pipe bodies connected to the upper and lower base ends are interposed in the vertical member 11, that is, the left and right sockets 130a and 130b, It is assumed that the base end is pivotally attached to the longitudinal member 11 at 131a and 131b .

And also, in this folded body 13, the tip of Hidarikatatai 130 and Migikatatai 131 is coupled to the hinge coupling portion 132, the hinge coupling portion 132 extends longitudinally along the longitudinal member 11 Core body 132a, and a socket 132b for a hinge made of a pipe body through which the core body 132a is inserted, and either the left side body 130 or the right side body 131 is placed on the upper and lower ends of the core body 132a. The tip of each of the left body 130 and the right body 131 is connected to the hinge socket disposed between the upper and lower ends of the core body 132a, while the tip is connected to each other. Thus, it is assumed that the scaffolding plate is allowed to be bridged to the lateral connecting material on the left side surface and the right side surface.
Note that the hinge socket 132b is formed to be longer than the upper sockets 130a and 130b and the lower sockets 131a and 131b described above.

  Therefore, in the extension frame 8, the folding body 13 is folded while exhibiting the same effects as the folding body 3 described above.

  That is, when the folding body 13 is folded so that the left side body 130 and the right side body 131 overlap each other with the hinge coupling portion 132 as the center, as in the case shown in FIG. The body 131 is not in an attitude of sandwiching the hinge coupling portion 132, and therefore, it is possible to prevent mischievous bulkiness.

And even in this folding body 13, it consists of a core body 132a in which the hinge coupling portion 132 extends in the vertical direction, and a hinge socket 132b made of a pipe body through which the core body 132a is inserted. whereas the tip of the left body 130 to form a folded body 3 on the lower end portion of the core body 132a are respectively connected, the tip of Migikatatai 131 in the socket 132b of the hinge in between the upper and lower ends Are connected to each other , as in the case of the folding body 3 described above, when the component structure is viewed, it becomes a simple component structure, and therefore, the product cost can be expected to be reduced by reducing the component cost. .
In addition, in the hinge coupling portion 132 of the present invention, a hinge socket 132b made of a pipe body is interposed in the longitudinally extending core body 132a, and the tip of the left side body 130 is the core. It is connected to the upper and lower ends of the body 132a, the tip of the right body 131 is connected to a socket 132b for hinges between the upper and lower ends of the core 132a, and the height position of the upper end of the core 132a is vertical. The upper position of the sockets 130a and 131a on the material 11 is the same height position, and the height position of the lower end of the core body 132a is the position of the lower sockets 130b and 131b on the vertical material 11. Since the height is higher than this, the hinge coupling portion 132 is not exposed to bulkiness.

  Even in the adjustment frame 8, as shown in FIG. 10, it is possible to construct the scaffolding plate 4 by using the horizontal connecting material 12, and a pair of vertical plates on the left and right sides on the front and back sides. The handrail body 6 can be connected to the upper end of the material 11.

  Next, when the scaffold device according to the present invention is installed on an inclined ground or a stair with steps on the left and right sides, the height adjusting frame 9 is used as shown in FIGS.

  That is, the height adjustment frame 9 forms one of the left and right side surfaces, that is, in the drawing, the upper end portions are connected to the lower end portions of the vertical struts 1 that form a pair on the left and right sides that form the right side surface. As shown in FIG. 15, the pipe body 91 is integrally connected by a plurality of horizontal connecting members 92 in the vertical direction. It is supposed to become.

  The height adjustment frame 9 is formed such that the upper end side of the auxiliary pipe 93 is inserted into the lower end side of the pipe body 91 so as to be capable of appearing and retracting. It is supposed to be.

  In this height adjustment frame 9, the auxiliary pipe 93 has a plurality of lateral holes 93a (see FIG. 15A) opened at appropriate intervals in the vertical direction, although not shown. In addition, by inserting a pin through which the pipe 91 is inserted into the selected horizontal hole 93a, the protruding and appearing position with respect to the pipe 91 is determined.

  Therefore, in this height adjustment frame 9, the auxiliary pipe 93 may be pulled out from the pipe 91 so as to correct the so-called difference in height between the left and right sides, but in order to realize more appropriate correction. It is preferable that a correction plate is interposed between the lower end of the auxiliary pipe 93 and, for example, the ground surface.

  On the other hand, as shown in FIGS. 15 (A) and 15 (D), the height adjusting frame 9 has a latch 94 at the upper end of the pipe body 91. It is assumed that there is a groove 94a that permits the introduction from above both ends 2a of the horizontal connecting member 92 connected to the outer periphery of the support column 1.

  Further, the height adjustment frame 9 has a holder 95 connected to the pipe body 91 as shown in FIG. 15C so that the holder 95 holds the vertical support 1. It is going to be.

  Therefore, the height adjusting frame 9 is in a state in which the vertical support 1 is suspended by the latch 94, and in this state, the pipe body 91 with respect to the vertical support 1 by the holder 95 is provided. Is supposed to prevent the displacement.

  The height adjustment frame 9 has a stopper 96 as a connecting tool shown in FIG. 16, and this stopper 96 is a hook pin that simultaneously holds the vertical strut 1 and the pipe t91. 96a and a bracket 96b interposed between the hook pin 96a and sandwiching the vertical support 1 and the pipe 91 between the hook pin 96a, and the wing nut 96c is screwed to the hook pin 96a. It is assumed that the vertical strut 1 and the pipe 91 are held in an integrated state by the penetration.

  FIG. 17 shows one usage example of the scaffold device according to the present invention. In this usage example, the scaffold plate 4 is assumed to be installed on the horizontal connecting member 2 on the lower side when compared. It is assumed that the body 6 (see FIGS. 1 and 3) is used with the body 6 removed.

  However, even in this usage example, since the vertical support column 1 has the caster 5 at the lower end, the worker who interrupts the work descends from the scaffold plate 4 and moves the scaffold device to a predetermined position. Then, it becomes possible to enter the scaffolding plate 4 again and continue the work.

  FIG. 18 shows another usage example of the scaffold device according to the present invention.
