[0005] [Patent Document 1] Patent No. 6726975 [Patent Document 2] Patent No. 6836843 Summary of the Invention [Problem to be solved by the invention]

[0006] Since a large number of baseboard devices are mounted in accordance with the spacing between the posts in the scaffolding structure, it is necessary that the mounting work can be carried out quickly and easily, and that the baseboard devices are stable when mounted.

[0007] In particular, since the baseboard device is mounted by detachably engaging the mounting means with the support, the mounting means itself must be highly safe, and it is necessary to meet this requirement. Furthermore, it is desirable to provide a safety means that can prevent the baseboard device from falling off.

[0008] On the other hand, when transporting and storing a large number of baseboard devices that have been removed when the scaffolding is dismantled, it is preferable that they be able to be stacked one on top of the other, and it is desirable that they be configured so that they do not easily collapse when stacked.

[0009] An object of the present invention is to provide a baseboard device that solves these problems. [Means for solving the problem]

[0016] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] 1 shows a rolling tower as an example of a scaffolding structure, in which a pair of posts 1, 1 are arranged spaced apart in the Y direction with respect to the X and Y directions which are orthogonal on a plane, and a work floor 4 is formed by connecting the posts 1, 1 spaced apart in the Y direction with a cross member 2, and erecting scaffolding boards 3 on the cross members 2, 2 spaced apart in the X direction. In the example shown in the figure, connecting members and diagonal members are provided between adjacent posts 1, 1, and an enclosed work space is formed on the work floor 4.

[0018] Therefore, with respect to the inside and outside of the work space, a baseboard device 5 is mounted along the side of the work floor 4 facing from the inside to the outside. In the case of the rolling tower shown in the figure, it is arranged along the four sides surrounding the work floor 4, and both ends of the baseboard device 5 are respectively fastened and detachably engaged to the support posts 1.

[0019] However, it should be understood that the baseboard device 5 of the present invention can also be mounted on scaffolding structures other than the rolling tower shown in the illustration, and includes, for example, a configuration in which a number of baseboard devices 5 are mounted between adjacent supports 1 and arranged in series toward the girder or gable direction of the scaffolding boards 3 that form the work floor 4 in a temporary scaffolding in which a number of supports 1 are erected at intervals in the X and Y directions.

[0020] (Configuration of baseboard device) 2 to 12 show a baseboard device 5 according to an embodiment of the present invention. The baseboard device 5 comprises a metal baseboard body 6 that straddles a pair of adjacent posts 1, 1, with metal edge members 7L, 7R attached to both the left and right ends of the baseboard body 6. Each of the edge members 7R, 7L is provided with fixed mounting means 8 and movable mounting means 9, both made of metal, that are fastened to the post 1 in a detachable manner.

[0021] In this case, the fixed mounting means 8 and the movable mounting means 9 are provided at different height positions so as not to overlap each other in the height direction. As a result, when adjacent baseboard devices 5, 5 are arranged in series across a single support post 1 as shown in Fig. 9, or when adjacent baseboard devices 5, 5 are arranged orthogonal to each other across a single support post 1 as shown in Fig. 10, the fixed mounting means 8 and movable mounting means 9 of the adjacent baseboard devices 5, 5 are locked and fixed to the single support post 1 from positions distributed above and below.

[0022] When the baseboard device 5 is installed, the side facing the work space is the inside F1 and the side facing the external space is the outside F2.The baseboard body 6 has an upper rail portion 11 and a lower rail portion 12, each having a groove-shaped cross section, extending from the upper and lower edges of the strip-shaped plate portion 10 arranged on the inside F1 toward the outside F2.

[0023] The edge members 7L and 7R are located at the left and right ends of the baseboard body 6, respectively, and integrally form an inner plate portion 13 and an outer plate portion 14 that sandwich the strip-shaped plate portion 10 and the upper and lower rail portions 11 and 12, and an intermediate plate portion 15 that connects the inner and outer plate portions 13 and 14, and are fixed to the baseboard body 6 by fasteners 16 such as rivets as shown in the figure.

[0024] In this case, the intermediate plate portion 15 is bent at an acute angle from the outer plate portion 14 and extends toward the inner plate portion 13, thereby forming an inclined surface 17 as shown in Figure 4(B) and Figures 11(A) and (B).

[0025] (Fixed mounting means) The fixed mounting means 8 is provided on the outer plate portion 14 of one of the edge members 7L, 7R, in the illustrated embodiment, the right edge member 7R, and is arranged in the lower half of the outer plate portion 14.

[0026] The fixed mounting means 8 has a fixed base 18 located on the inside F1 and a fixed arm 19 located on the outside F2, spaced apart from each other with respect to the inside F1 and the outside F2, and an opening 20 is formed by opening the tips of the fixed base 18 and the fixed arm 19. Therefore, when the support 1 enters through the opening 20, the support 1 is embraced by the fixed base 18 and the fixed arm 19. It is preferable that the inner edges of the fixed base 18 and the fixed arm 19 form arc edges that follow the circumferential surface of the support 1, as shown in the figure.

[0027] In the illustrated embodiment, the fixed mounting means 8 is formed by bending a single metal plate, and a pair of upper and lower fixed bases 18, 18 are provided by bending the upper and lower edge portions of the flat plate portion 21, and a pair of upper and lower fixed arms 19, 19 are formed by arms extending from the fixed bases 18. The tail end of the flat plate portion 21 is fixed to the outer plate portion 14 with fasteners 22 such as rivets, whereby the fixed bases 18, 18 and fixed arms 19, 19 are configured to protrude from the edge member 7R.

[0028] In this case, it is preferable that the pair of upper and lower fixed arms 19, 19 have bent portions 19a, 19a at their bases as shown in the figure, so as to increase the vertical distance between the pair of fixed arms 19, 19. As a result, as shown in Figure 2, the pair of fixed bases 18, 18 have an outer dimension W1 in the vertical direction, and the inner dimension W2 in the vertical direction of the pair of fixed arms 19, 19 is formed so that W2 ≥ W1, and as will be described later, when multiple baseboard devices 5, 5 are stacked one on top of the other, the pair of upper and lower fixed bases 18, 18 of one baseboard device 5 are fitted between the pair of upper and lower fixed arms 19, 19 of the other baseboard device 5.

[0029] (Movable mounting means) The movable mounting means 9 is provided on the edge member opposite to the edge member on which the fixed mounting means 8 is provided, i.e., in the illustrated embodiment, on the outer plate portion 14 of the left edge member 7L, and is arranged in the upper half of the outer plate portion 14.

[0030] The movable mounting means 9 is configured by arranging a fixing bracket 23 on the inner side F1 and a movable arm 24 on the outer side F2, with respect to the inner side F1 and the outer side F2, and is configured to be engaged and fixed to the support 1 by attaching the fixing bracket 23 to the inner side of the support 1 and attaching the movable arm 24 to the outer side of the support 1.

[0031] The fixing bracket 23 is formed into a horizontal groove shape by bending a single metal plate, and a pair of groove side walls 26, 26 is formed by bending the upper and lower edges of the groove bottom wall 25. In this case, the groove side walls 26, 26 form a bracket portion 26a for pivotally supporting the movable arm 24 and an attachment portion 26b extending from the bracket portion 26a toward the tip to be attached to the inside of the support column 1, and the attachment portion 6b has an arcuate edge that follows the circumferential surface of the support column. A notch 27 is formed in the groove bottom wall 25 between the attachment portions 6b, 6b, and the tail end of the groove bottom wall 25 is fixed to the outer plate portion 14 with a fastener 28 such as a rivet, causing the attachment portions 6b, 6b to protrude from the edge member 7L.

[0032] In contrast, the movable arm 24 has a pivotal connection portion 29 formed in an approximately U-shaped cross section that is fitted between the bracket portions 26a, 26a and is rotatably supported by a pivot 30, an arm portion 31 extending from the pivotal connection portion 29, and a claw portion 32 extending from the arm portion 31.

[0033] The movable arm 24 is resiliently biased by a spring 33 so that the arm portion 31 rotates to a position where it overlaps the groove bottom wall 25 of the fixing bracket 23, and at this time, the claw portion 32 passes through the notch 27 and protrudes toward the inside F1 of the edge member 7L. As a result, when multiple baseboard devices 5, 5 are stacked together, as will be described later, the claw portion 32 of the movable arm 24 of one baseboard device 5 is fitted between the pair of upper and lower splice portions 6b, 6b of the other baseboard device 5.

[0034] (How to install the baseboard device) When the baseboard device 5 is to be installed between a pair of posts 1, 1, of the fixed mounting means 8 and the movable mounting means 9, the fixed mounting means 8 is first engaged with the post 1, as shown in Figure 7(A). As shown in the figure, the fixed mounting means 8 is formed like a fork with a fixed base 18 and a fixed arm 19, so that by moving the baseboard device 5 from the outside F2, the post 1 can be inserted between the fixed base 18 and the fixed arm 19, and the post 1 can be easily embraced.

[0035] As shown in Figure 7(A), the movable arm 24 of the movable mounting means 9 is normally held in a rest position P1 in which it is superimposed on the groove bottom wall 25 of the fixed metal fitting 23 by receiving the resilient biasing force of the spring 33. Then, when the movable arm 24 is rotated against the spring 33 and reversed to assume a standby position P2, the fixed metal fitting 23 comes into contact with the support post 1, and then the movable arm 24 is rotated by the spring 33, as shown in Figure 7(B), until it assumes an operating position P3 and comes into resilient contact with the support post 1. In this state, the fixed metal fitting 23 and the movable arm 24 clamp the support post 1 from the inside F1 and the outside F2 with the resilient biasing force, and are thereby engaged and fixed to the support post 1.

[0036] Furthermore, when removing the baseboard device 5, the movable arm 24 is rotated to the standby position P2 to move the movable mounting means 9 away from one of the support posts 1, and in that state, the fixed mounting means 8 is pulled away from the other support post 1.

[0037] (Effect when multiple baseboard devices are arranged in series) 9 shows adjacent baseboard devices 5A and 5B arranged in series. In this case, the fixed mounting means 8A of one baseboard device 5A is positioned below and locked and fixed to one support post 1, and the movable mounting means B9 of the other baseboard device 5B is positioned above and locked and fixed to the same post 1. As a result, the adjacent baseboard devices 5A and 5B are arranged in series and aligned at the same height.

[0038] As shown in the figure, the fixed mounting means 8 and the movable mounting means 9 are always positioned on top and engaged and fixed to the support 1, making it easy to rotate the movable arm 24 as described above.

[0039] (Effect when multiple baseboard devices are arranged orthogonally) 10 and 11 show a state in which adjacent baseboard devices 5A and 5C are arranged perpendicular to each other. In other words, as shown in Fig. 1, at the corner of the work floor 4, the baseboard devices are mounted in a state in which they are arranged in the Y direction and the X direction with one support post 1 between them.

[0040] As in the case described above, the fixed mounting means 8A of one baseboard device 5A is positioned at the lower side and locked and fixed to one support 1, and the movable mounting means 9C of the other baseboard device 5C is positioned at the upper side and locked and fixed to the same support 1.

[0041] The base board device 5A and base board device 5C, which are arranged perpendicular to each other, have their edge members 7R, 7L butted against each other, and one inclined surface 17A and the other inclined surface 17C are made to abut against each other between the opposing intermediate plate portions 15, 15. As a result, as shown in Figure 11(A), even if the base board device 5A and base board device 5C try to move in the direction toward the inside F1 indicated by the arrow M, the inclined surfaces 17A and 17C interfere with each other in the direction of movement M and complement each other to prevent the movement, so the movement is prevented.

[0042] In other words, if the fixed metal fitting 23 of the movable mounting means 9 is moved in the movement direction M due to an external force, there is a risk that the movable arm 24 will rotate against the spring 33 toward the standby position P2, but by providing the inclined surface 17, such a risk is prevented from occurring.

[0043] (Configuration of inclined surface) As shown in FIG. 4(B), it is preferable that the inclined surface 17 is formed midway between the X and Y directions extending from the center of the support 1, that is, along the C direction inclined at 45 degrees relative to the X and Y axes.

[0044] However, it is not necessary for the C direction to be 45 degrees. For example, as shown in Figure 11(B), the inclined surface 17A of the edge member 7R located on the right side of one baseboard device 5A is inclined at an angle θA from the Y axis, and the inclined surface 17C of the edge member 7L located on the left side of the other baseboard device 5C is inclined at an angle θB from the X axis.In this case, the angles may be different, such as θA > θB.In short, it is sufficient that the inclined surface 17A and the inclined surface 17C are configured to overlap each other.

[0045] (Action when removing orthogonally arranged baseboard devices) As shown in Figure 10, the perpendicularly arranged Q baseboard device 5A and baseboard device 5C abut the inclined surfaces 17A and 17C of the butted edge members 7R and 7L, respectively, so that movement toward the inside F1 is prevented.

[0046] Therefore, when removing the baseboard device 5C from this state, the movable mounting means 9C at one end (the left end in the figure) of the baseboard device 5C is moved upward along the support 1 together with the baseboard body 6, as shown by the dotted line, and the inclined surface 17C is removed from the position above the inclined surface 17A, and then moved toward the inside F1.

[0047] At this time, the baseboard device 5C places the baseboard body 6 in an inclined position by moving one end (the left end shown in the figure) upward while the fixed mounting means 8C at the other end (the right end shown in the figure) is engaged with the support 1, so that the movable mounting means 9C can be moved upward to the position shown by the dotted line in the figure.

[0048] In this way, by performing a series of operations in which the movable mounting means 9C is moved upward as indicated by arrow U and then inward as indicated by arrow F1, the movable arm 24C of the movable mounting means 9C is pushed by the support 1 against the spring 33 toward the standby position P2, thereby releasing the engagement with the support 1.From this state, if the baseboard body 6 is moved longitudinally, the fixed mounting means 8C is pulled out from the support 1, and the baseboard device 5C can be removed from the support 1, 1.

[0049] (Effect when storing multiple baseboard devices stacked together) 12 and 13 show the baseboard devices 5 stacked in a layered configuration for transport or storage. The baseboard devices 5A and 5D are stacked in the same direction, i.e., with the inner side F1 and the outer side F2 facing the same direction.

[0050] As described above, the fixed mounting means 8 protrudes from the edge member 7R of the base board body 6, and is configured so that the distance W2 between the inner surfaces of the pair of upper and lower fixed arms 19, 19 and the distance W1 between the outer surfaces of the pair of upper and lower fixed bases 18, 18 satisfy W2≧W1. Therefore, between the stacked base board devices 5A, 5D, the pair of upper and lower fixed bases 18D, 18D of one base board device 5D are fitted between the pair of upper and lower fixed arms 19A, 19A of the other base board device 5A, preventing misalignment of the base board devices 5A and 5D in the short direction of the base board body 6.

[0051] In addition, the movable mounting means 9 protrudes from the edge member 7L of the baseboard body 6, and between the stacked baseboard devices 5A and 5D, the claw portion 32D of the movable arm 24D of the other baseboard device 5D is inserted between the groove side walls 26A, 26A of the fixing bracket 23A of one baseboard device 5A, thereby preventing misalignment of the baseboard devices 5A and 5D in the short direction of the baseboard body 6.

[0052] Furthermore, in the illustrated embodiment, a support portion 34 that forms a sloping edge is provided at the rear end (the portion located above the edge member 7R) of the fixed base 18 of the fixed mounting means 8. Also, a support portion 35 that forms a sloping edge is provided at the rear end (the portion located above the edge member 7L) of the fixed metal fitting 23 of the movable mounting means 9.

[0053] 13, between the stacked baseboard devices 5A and 5D, the support portions 34, 35 of one baseboard device 5A are configured to support along the inclined surfaces 17 of the intermediate plate portions 15 of the edge members 7L, 7R of the other baseboard device 5D. This prevents misalignment of the baseboard devices 5A and 5D in the longitudinal direction of the baseboard body 6. Moreover, the stacked baseboard devices 5A, 5D are stacked with gaps between them, without the baseboard bodies 6, 6 coming into surface contact with each other, preventing scratches from occurring.
