Embodiment for Carrying Out the Invention

[0016] [Scaffold 10] First, with reference to FIGS. 1 to 7, the scaffold 10 according to an embodiment of the present invention will be described. In the scaffold 10 described in this specification, the rotation axis direction of the ladder bodies 2·2 in each figure (the laying direction of the treads 4) is taken as the left-right direction of the scaffold 10, and the direction orthogonal to the left-right direction in the horizontal direction (the opening and closing direction of the ladder bodies 2·2) is taken as the front-back direction of the scaffold 10.

[0017] As shown in FIG. 1, the scaffold 10 according to this embodiment includes a frame body 1 formed in a rectangular shape in plan view, a pair of ladder bodies 2·2 rotatably provided at both ends in the longitudinal direction of the frame body 1 (the front-back direction of the scaffold 10), and a plate-like top plate 3 detachably attached to the frame body 1. In the scaffold 10 according to this embodiment, the frame body 1, the ladder bodies 2·2, and the top plate 3 are mainly composed of light metal parts made of aluminum or an aluminum alloy.

[0018] As shown in FIGS. 2 and 3, the frame body 1 is formed in a rectangular shape in plan view by two end support portions 11·11 provided at both ends in the longitudinal direction of the frame body 1 and two long frames 12·12 provided at both ends in the short direction of the frame body 1. Also, at the middle part in the longitudinal direction of the frame body 1, two middle support portions 13·13 for connecting the opposing long frames 12·12 are provided.

[0019] The upper ends of the pair of ladder bodies 2·2 are rotatably connected to both ends in the longitudinal direction of the frame body 1 by hinges 6·6. Specifically, the hinge 6 rotatably connects the frame body 1 and the ladder body 2 so that the ladder body 2 approaches the frame body 1 (see FIG. 3).

[0020] Each ladder body 2 includes a pair of columns 5·5 that are elongated bodies. The columns 5·5 are arranged in a substantially inverted V shape when viewed from the front such that the distance between them is greater at the lower side than at the upper side. The scaffold base 10 according to the present embodiment includes four columns 5. Each column 5 is formed in a shape that bends at two locations along the longitudinal direction for the purpose of ensuring strength and the like, and the cross-sectional shape orthogonal to the longitudinal direction is substantially U-shaped.

[0021] Each column 5 is provided with a telescopic leg 5a that can move forward and backward in the longitudinal direction of the column 5. By adjusting the extension length of the telescopic leg 5a from the column 5, the height of the top plate 3 in the scaffold base 10 can be adjusted (refer to the phantom line shown in FIG. 2). In the scaffold base 10 according to the present embodiment, an end fitting is fixed to the lower end of the telescopic leg 5a.

[0022] Between the pair of columns 5·5 in the ladder body 2, a plurality of treads 4·4···, which are hollow cylindrical members, are bridged at a predetermined interval. The tread 4 is formed by cutting a linear extrusion molded product having a predetermined cross-sectional shape to a predetermined length. Each tread 4 is fixed between the opposing columns 5·5 by a fixture.

[0023] The scaffold base 10 can mainly take the following two forms according to the angle formed by the ladder body 2 with respect to the frame body 1. The first form of the scaffold base 10 is a form in which the ladder bodies 2·2 are separated from the frame body 1 as shown in FIG. 1 and the scaffold base 10 is supported by four columns 5 (hereinafter, this form will be described as the "use state"). The scaffold base 10 in the use state is used in a state of standing on the ground or the floor. In the scaffold base 10, the hinge 6 is provided with a locking mechanism 6a for restricting the rotation of the ladder bodies 2·2 with respect to the frame body 1 in the use state.

[0024] The second form of the scaffold base 10 is a form in which the ladder bodies 2·2 are brought close to the frame body 1 as shown in FIG. 3 (hereinafter, this form will be described as the "storage state"). The storage state of the scaffold base 10 is mainly adopted during storage or transportation.

[0025] In the scaffold base 10 according to this embodiment, the top plate 3 is composed of a plate member 30 with the front, rear, left, and right ends bent downward, an insertion portion 32 with a U-shaped cross-section fixed to the lower surface of the plate member 30, a fixing belt 33 which is a regulating member for regulating the relative displacement between the top plate 3 and the frame body 1, etc.

[0026] In the scaffold base 10 according to this embodiment, both longitudinal ends of the top plate 3 are supported by the end support portions 11·11 in the frame body 1. Specifically, as shown in FIG. 4, the end support portion 11 is formed with a support piece 11a extending inward in the front-rear direction (toward the side of the opposing end support portion 11). When the longitudinal end of the top plate 3 is placed on the support piece 11a, the end of the top plate 3 is supported by the end support portion 11.

[0027] Also, the middle portion in the longitudinal direction of the top plate 3 is supported by the middle support portions 13·13 in the frame body 1. As shown in FIG. 2, cutout portions 31·31 are formed at positions corresponding to the middle support portions 13·13 on the lower side of the side edges of the plate member 30 of the top plate 3. When the top plate 3 is assembled to the frame body 1, as shown in FIG. 4, the middle support portion 13 is inserted into the cutout portion 31.

[0028] As shown in FIG. 4, a recess 31a is formed at the upper part of the cutout portion 31. Also, on the upper surface of the middle support portion 13, a positioning portion 13a protruding upward is formed along the longitudinal direction of the middle support portion 13. When the top plate 3 is assembled to the frame body 1 and the middle support portion 13 is inserted into the cutout portion 31, the positioning portion 13a is inserted into the recess 31a.

[0029] As shown in FIGS. 2 and 4, groove portions 13b for attaching other members are formed on the front-rear side surfaces of the middle support portion 13. Specifically, by inserting a nut member (not shown) into the groove portion 13b, it becomes possible to attach other members via a bolt member screwed into this nut member. Also, it is possible to attach other members by directly locking a hook-shaped bracket or the like to the groove portion 13b.

[0030] In the scaffold base 10 according to the present embodiment, two insertion portions 32·32 are fixed downward at positions corresponding to the middle support portions 13·13 on the lower surface of the top plate 3. When the top plate 3 is assembled to the frame body 1, as shown in FIG. 4, the middle support portion 13 is inserted inside the insertion portion 32. By inserting the middle support portion 13 inside the insertion portion 32, displacement of the top plate 3 with respect to the frame body 1 can be suppressed.

[0031] In the scaffold base 10 according to the present embodiment, a fixing belt 33 is provided as a regulating member that regulates displacement of the top plate 3 and the middle support portion 13 in a direction away from each other. Specifically, as shown in FIG. 4, a through portion for inserting the fixing belt 33 is formed between the lower surface of the plate member 30 and the insertion portion 32 on the top plate 3.

[0032] A belt locking member 34 is fixed to one end portion of the fixing belt 33. Also, a surface fastener 35 composed of a first surface fastener 35a and a second surface fastener 35b is fixed to the other end side of the fixing belt 33.

[0033] When fixing the top plate 3 to the frame body 1, as shown in FIG. 4, with the fixing belt 33 inserted through the through portion between the plate member 30 and the insertion portion 32, the fixing belt 33 is wound around the periphery of the insertion portion 32 and the middle support portion 13. Then, the other end portion of the fixing belt 33 is wound around the belt locking member 34, and the first surface fastener 35a and the second surface fastener 35b are engaged. Thereby, displacement of the top plate 3 and the middle support portion 13 in a direction away from each other is regulated.

[0034] As shown in FIG. 2, when the surface fastener 35 is separated on the fixing belt 33, the top plate 3 can be removed from the frame body 1. That is, the top plate 3 is configured to be detachable with respect to the frame body 1.

[0035] As shown in FIGS. 5 to 7, in the scaffold base 10 according to the present embodiment, with the top plate 3 removed, the frame body 1 is configured to be able to assemble a plurality of divided top plates 8 that are smaller than the top plate 3. The divided top plates 8 in the present embodiment adopt two types: a long top plate 8L with a large length dimension and a short top plate 8S with a small length dimension. The scaffold base 10 according to the present embodiment is configured to assemble a total of six divided top plates 8, two in the left - right direction and three in the front - rear direction (two long top plates 8L and one short top plate 8S).

[0036] When the divided top plate 8 is assembled to the frame body 1, the longitudinal end portions are supported by the end support portions 11 or the middle support portions 13. Specifically, as shown in FIG. 7, the end portions of the divided top plate 8 near the end support portion 11 are placed on the support pieces 11a. Also, the end portions of the divided top plate 8 near the middle support portion 13 are placed on the upper surface of the middle support portion 13. At this time, the positioning portion 13a formed on the middle support portion 13 functions as a restricting portion that restricts the horizontal displacement of the divided top plate 8.

[0037] As shown in FIG. 6, on the lower surface of the divided top plate 8, a groove portion 8a for attaching other members is formed. Specifically, by inserting a nut member (not shown) into the groove portion 8a, it is possible to attach other members via a bolt member that screws into this nut member. Also, it is possible to attach other members by directly locking a hook - shaped bracket or the like to the groove portion 8a.

[0038] As described above, in the scaffold base 10 according to the present embodiment, when used for other purposes such as eating, the top plate 3 can be removed and the divided top plates 8 can be assembled to the frame body 1 for use. On the other hand, when the divided top plates 8 are not used, a plurality of divided top plates 8 can be stacked and stored, so that it can be easily carried.

[0039] In this way, the scaffold base 10 according to the present embodiment has a configuration in which the top plate 3 can be removed and exchanged with a plurality of divided top plates 8, making it possible to make the divided top plates 8 compact when not in use and facilitating the carrying of the scaffold base 10.

[0040] In addition, in the scaffold base 10 according to the present embodiment, when the top plate 3 is assembled to the frame body 1, the middle support portion 13 is configured to be inserted into the notch portion 31. Thereby, the top plate 3 can be easily positioned with respect to the frame body 1, and the top plate 3 can be prevented from being displaced from the frame body 1.

[0041] In addition, in the scaffold base 10 according to the present embodiment, a fixing belt 33 is provided as a regulating member that regulates the displacement of the top plate 3 and the middle support portion 13 in a direction away from each other. Thereby, it is possible to prevent the top plate 3 from lifting off or coming off from the frame body 1. In addition to the fixing belt 33, as a regulating member for regulating the displacement between the top plate 3 and the middle support portion 13, for example, other configurations such as buckles, clips, screwing, string members, magnets, latch members, surface tapes, and seal members can also be adopted. It is also possible to provide the regulating member on the middle support portion 13.

[0042] In addition, in the scaffold base 10 according to the present embodiment, an insertion portion for inserting the fixing belt 33 is formed between the lower surface of the plate member 30 and the inserted portion 32 on the top plate 3. Thereby, it becomes possible to provide the fixing belt 33, which is a regulating member, on the top plate 3 with a simple configuration.

[0043] In addition, in the scaffold base 10 according to the present embodiment, the positioning portion 13a formed on the middle support portion 13 functions as a regulating portion that regulates the horizontal displacement of the divided top plate 8. Thereby, the posture of the divided top plate 8 when the divided top plate 8 is assembled to the frame body 1 can be stabilized. It is also possible to adopt a configuration in which a regulating portion is provided on the end support portion 11.

[0044] In addition, in the scaffold base 10 according to the present embodiment, groove portions 13b and 8a for attaching other members are formed in the middle support portion 13 and the divided top plate 8. Thereby, it becomes possible to attach other members such as lighting fixtures, cooking utensils, trays, rope materials such as guide lines, and optional holders such as hooks to the scaffold base 10 with a simple configuration.

[0045] [Retention member 40] Next, with reference to FIGS. 8 to 13, the holding member 40 that is detachable from the frame body 1 of the scaffold base 10 will be described. In FIGS. 8, 12, and 13, the scaffold base 10 to which the holding member 40 is assembled is provided with a split top plate 8 with respect to the frame body 1, but the holding member 40 can also be assembled to the scaffold base 10 provided with the top plate 3.

[0046] The scaffold base 10 for assembling the holding member 40 is such that the top plate 3 or the split top plate 8 is detachable from the frame body 1 as in this embodiment. Therefore, it is possible to easily perform the attachment / detachment work of the holding member 40 with the top plate 3 or the split top plate 8 removed from the frame body 1.

[0047] Note that it is also possible to adopt a configuration in which the holding member 40 is assembled to the scaffold base 10 with the top plate 3 (split top plate 8) fixed. Further, the holding member 40 is not limited to the scaffold base 10 provided with the ladder body 2·2, and can be assembled to any pedestal member provided with legs.

[0048] As shown in FIGS. 8, 12, and 13, the holding member 40 is used in a state of being assembled to the scaffold base 10. The holding member 40 is used alone when a single support member such as the first option member 50 (rod body 51) holds one option member, as shown in the first scaffold base unit U1 in FIG. 12. Further, the holding member 40 is used in a set of two when two support members such as the second option member 60 and the third option member (rod bodies 61·71) hold two option members, as shown in the second scaffold base unit U2 in FIG. 13.

[0049] As shown in FIG. 9, the holding member 40 includes a pair of support members 41·41, two shafts 42·42, a compression spring 43 as a biasing member, a fixing screw 45, and the like. The support member 41 is a resin member in which a fixing portion 41a penetrating in the vertical direction is formed. By tightening the fixing screw 45 screwed into the inside of the fixing portion 41a with the rod body of the option member inserted into the fixing portion 41a, the rod body of the option member is fixed to the support member 41.

[0050] As shown in Fig. 10, the fixing portion 41a is formed as two inclined surfaces whose side surfaces on the side opposite to the fixing screw 45 are symmetric in a plan view with respect to the axis of the fixing screw 45. Thus, when the rod body is cylindrical, when the fixing screw 45 is tightened, it becomes possible to stably support the rod body at three points by the fixing screw 45 and the two inclined surfaces. Further, since the side surface of the rod body is in line contact with the two inclined surfaces, the rod body can be stably supported at the fixing portion 41a, and rattling of the rod body can be suppressed.

[0051] As shown in Fig. 9, engaging portions 44 are formed on the upper surface of the support member 41 toward both end sides of the holding member 40. In a state where the holding member 40 is assembled to the frame body 1, the engaging portion 44 engages with the lower side 12a of the long frame 12 provided on the long side of the frame body 1. In other words, the holding member 40 is assembled to the frame body 1 by the engaging portions 44 in the respective support members 41·41 engaging with the lower side 12a of the long frames 12 facing each other in the frame body 1.

[0052] Also, as shown in Fig. 10, engaging protrusions 41b·41b are formed on one side portion of the lower surface of each support member 41, and engaging grooves 41c·41c are formed on the other side portion. Then, as shown in Fig. 11, the engaging protrusions 41b·41b in the holding member 40 are inserted into the engaging grooves 41c·41c formed in the support members 41 of the other holding member 40, and the engaging protrusions 41b·41b formed in the support members 41 of the other holding member 40 are inserted into the engaging grooves 41c·41c in the holding member 40. Thereby, the holding member 40 can be combined with the other holding member 40.

[0053] As described above, the holding member 40 can be combined with the other holding member 40 in pairs of two. Thereby, a pair of holding members 40·40 can be integrally assembled to facilitate carrying.

[0054] In the holding member 40, a pair of support members 41, 41 are connected by two shafts 42, 42. The support members 41, 41 in the holding member 40 are formed in the same shape as each other and are arranged in a posture facing each other. Also, the shafts 42, 42 are formed in the same shape as each other and are arranged in opposite directions. Hereinafter, the assembly configuration of one support member 41, the shafts 42, 42 will be described.

[0055] As shown in FIG. 10, a locked portion 42c is formed at one end of the shaft 42. Also, a locking portion 41d, which is an elastic piece, is formed to protrude toward the shaft 42 in the vicinity of the hole into which one end side of the shaft 42 is inserted in the support member 41. When one end side of the shaft 42 is inserted into the support member 41, the locked portion 42c is locked to the locking portion 41d, so that the shaft 42 is fixed to the support member 41 without rattling. That is, since the shape of the holding member 40 can be stabilized, it is possible to suppress rattling when the holding member 40 is assembled to the scaffold base 10.

[0056] Also, as shown in FIG. 10, a regulating portion 42a and a retaining portion 42b are provided at the other end of the shaft 42. Also, a compression spring 43 is inserted between the regulating portion 42a and the support member 41. When the compression spring 43 tries to extend in a state where the other end of the shaft 42 is inserted through the support member 41, the compression spring 43 biases the pair of support members 41, 41 in a direction to separate from each other.

[0057] As described above, in the holding member 40 according to the present embodiment, one (the right side in FIG. 9) support member 41 has one end side (the front side in FIG. 9) of one shaft 42 fixed thereto, and the other end side (the back side in FIG. 9) of the other shaft 42 slidably inserted therein. Also, the other (the left side in FIG. 9) support member 41 has one end side of the other shaft 42 fixed thereto, and the other end side of one shaft 42 slidably inserted therein. Thus, in the holding member 40, the support members 41, 41, the shafts 42, 42, the compression spring 43, etc. are configured to be assembled without using other fastening parts, adhesives, etc.

[0058] Further, in the holding member 40 according to the present embodiment, a compression spring 43 is provided on one of the shafts 42. And the compression spring 43 biases the one shaft 42 in a direction in which the one shaft 42 comes out of the other support member 41.

[0059] When assembling the holding member 40 to the scaffold base 10, as shown in FIG. 9, a pair of support members 41·41 are inserted inside the frame body 1 in a state of being close to each other. Then, the biasing force of the compression spring 43 separates the pair of support members 41·41. Further, each of the support members 41·41 is pressed against the opposing long frame 12 in the frame body 1. At this time, the engaging portion 44 of the support member 41 engages with the lower side 12a of the long frame 12. Thereby, the holding member 40 is assembled to the frame body 1.

[0060] As described above, the holding member 40 according to the present embodiment can be attached to and detached from the scaffold base 10 only by moving the support members 41·41 close to and away from each other. That is, the holding member 40 does not require other fixing members or the like, and can be attached to and detached from the scaffold base 10 with a simple configuration.

[0061] Further, the holding member 40 according to the present embodiment is assembled to the frame body 1 by the engaging portion 44 in each of the support members 41·41 engaging with the lower side 12a of the opposing long frame 12 in the frame body 1. Thereby, when a force is applied to the holding member 40, it is possible to prevent the holding member 40 from coming off the scaffold base 10. That is, it is possible to enhance the stability when the holding member 40 is assembled.

[0062] Further, in the holding member 40 according to the present embodiment, a pair of support members 41·41 are connected by two shafts 42·42, one of the shafts 42 is fixed to the support member 41, and the other of the shafts 42 is slidably inserted into the support member 41. Thereby, since the support members 41 can approach and separate in an opposing posture without relative rotation, the operability of the holding member 40 can be improved.

[0063] In addition, the holding member 40 according to the present embodiment is configured such that a compression spring 43, which is a biasing member, biases one shaft 42 in a direction in which the one shaft 42 comes out of the other support member 41. As a result, since a force can always be continuously applied in a direction in which the support members 41 and 41 move apart, it is possible to further enhance the stability during the assembly of the holding member 40.

[0064] Next, with reference to FIG. 12, a first scaffold unit U1 in which the holding member 40 is assembled to the scaffold 10 and used will be described. The first scaffold unit U1 is configured to assemble one holding member 40 to the scaffold 10 and use it.

[0065] In the first scaffold unit U1, a first option member 50 is assembled to the scaffold 10 via the holding member 40. The first option member 50 includes a rod body 51 that is a support column, a hook member 52 extending from the rod body 51, and a lighting fixture 53 locked to the hook member 52.

[0066] In the first scaffold unit U1, the rod body 51 is fixed to the fixing portion 41a of the holding member 40, whereby the first option member 50 is fixed to the scaffold 10. That is, the first scaffold unit U1 enables the assembly of the first option member 50 having a single support column to the scaffold 10 by using one holding member 40.

[0067] Next, with reference to FIG. 13, a second scaffold unit U2 in which the holding member 40 is assembled to the scaffold 10 and used will be described. The second scaffold unit U2 is configured to assemble two holding members 40 and 40 to the scaffold 10 and use them.

[0068] The second scaffold base unit U2 has a second option member 60 and a third option member 70 assembled to the scaffold base 10 via holding members 40, 40. The second option member 60 includes two rod bodies 61, 61 that are columns, a connecting rod 62 that connects the upper ends of the rod bodies 61, 61, and cooking utensils 63, 63 that are locked to the connecting rod 62. The third option member 70 includes two rod bodies 71, 71 that are columns and an extended top plate 72 fixed to the upper surface of the rod bodies 71, 71.

[0069] In the second scaffold base unit U2, the rod bodies 61, 71 are fixed to the fixing portions 41a of the respective holding members 40, whereby the second and third option members 60, 70 are fixed to the scaffold base 10.
