DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
1 to 8 show an embodiment of a truck hooking scaffold according to the present invention. As shown in FIGS. 1 and 2, the hooking scaffold 1 (hereinafter simply referred to as the scaffold 1) is detachably locked in a state of being spanned between the pair of left and right scaffolding pillars 2 and the pair of scaffolding pillars 2 and 2. The scaffold board 3 is provided.

  The pair of left and right scaffolding struts 2 are formed in the same shape, and have a horizontal strut 2a having a predetermined width (length) W1 (for example, W1 = 390 mm) and a rear end portion of the horizontal strut 2a at a substantially right angle upward. The vertical column 2b having a predetermined height H (for example, H = 690 mm) fixed by welding, and the inclined column 2c for reinforcement fixed by welding between a substantially intermediate portion in the height direction of the vertical column 2b and the front end of the horizontal column 2a. And a leg support 2d welded and fixed at a substantially right angle downward to the front end of the horizontal support 2a. And these each support | pillars 2a-2d are formed with the square pipe made from aluminum of the same external shape (section cross-sectional shape), and as shown in FIG. 6 in opening edge parts, such as the horizontal support | pillar 2a and the vertical support | pillar 2b, A resin cap 4 for preventing water and dust from entering the column 2 and enhancing safety is fitted and fixed.

  In addition, on the side of the vertical column 2b of the horizontal column 2a, there is provided a scaffolding plate mounting portion 2a1 on which locking metal fittings 6 at both ends in the longitudinal direction of the scaffolding plate 3 to be described later are mounted, and the vertical column 2b. On the rear surface of the upper end portion, a locking metal fitting 5 made of, for example, aluminum having a U-shaped cross section as a column locking portion is fixed by welding. In addition, a buffer material 8 such as rubber is fixed to a predetermined position (for example, substantially intermediate position) on the rear surface in the height direction of the vertical column 2b of each scaffold column 2, and the thickness of the buffer material 8 is, for example, as shown in FIG. 7, when an operator who attaches the scaffold 1 to the outer surface of the loading platform 11 of the light truck 10 gets on the scaffolding plate 3, the worker touches the outer surface of the loading platform 11, and the scaffolding plate 3 is in a substantially horizontal state ( That is, it is set to an appropriate size so that the vertical support 2b is in a substantially vertical state.

  Further, a flat ground plate 2d1 larger than the outer shape of the support column 2d is welded and fixed to the lower end of the leg support 2d. The height H1 of the leg support 2d is set so that the ground plate 2d1 has a predetermined gap (for example, a gap of about 20 mm) from the ground when the scaffold 1 is attached to the loading platform 11 of the light truck 10 as will be described later. When the worker rides on the scaffolding plate 3 and the grounding plate 2d1 of the leg column 2d contacts the ground with its weight, the scaffold column 2 tilts forward by a predetermined dimension or more as indicated by the arrow A in FIG. Being regulated.

  As shown in FIGS. 3 to 5, the scaffold plate 3 is an aluminum plate 3 a having a predetermined length L (for example, L = 756 mm) and a rectangular shape in plan view having a predetermined width W2 (for example, W2 = 185 mm). On the surface of the plate body 3a, ribs 3b and protrusions 3c as anti-slip are integrally formed by pressing or the like.

  That is, ribs 3b protruding upward by a predetermined dimension (for example, about 5 mm) are integrally formed on the front and rear end edges that are both ends in the width direction of the plate body 3a, and the center portion of the surface of the plate body 3a is formed upward. A large number of substantially hemispherical protrusions 3c having a predetermined dimension (for example, about 3 mm) projecting and having open side surfaces are integrally formed in a row. Of the slip stoppers, the ribs 3b prevent foot slip at the front and rear end portions of the scaffold plate 3, and the protrusions 3c prevent foot slip at the center portion. The ribs 3b and the protrusions 3c serving as slip stoppers also serve as reinforcement for the plate body 3a depending on their shapes.

  Also, an aluminum locking bracket 6 having a U-shaped cross section as a scaffolding plate locking portion is welded and fixed to the entire width direction of the back surface of both end portions in the longitudinal direction of the plate body 3a. The locking metal fitting 6 is mounted on the scaffolding board mounting part 2a1 from above, with the inner dimension set to be substantially the same as the outer dimension of the scaffolding board mounting part 2a1 of the horizontal column 2a. Thus, the mounting portion 2d1 is detachably locked in a three-surface fitting state. In addition, when the scaffold board 3 is mounted on the scaffold board placing portion 2a1 of the horizontal support 2a and assembled, the upper end of the rib 3b at the front end thereof can be substantially in contact with the back surface of the inclined support 2c. The back-and-forth movement with respect to the horizontal column 2a is restricted.

  Next, an example of how to use the scaffold 1 configured as described above will be described. First, as shown in FIG. 7, the storage shelf 12 mounted on the loading platform 11 of the light truck 10 includes, for example, six vertical columns 12a made of aluminum and a large number of horizontal columns that connect the vertical columns 12a. It is formed in a multi-stage type (for example, eight-stage type) by welding 12b so that the seedling box is stored in an inclined state on the horizontal support 12b from the left and right sides in the width direction so that the front side in the storage direction is lowered. It is configured.

  And in the case of rice planting, the scaffold 1 is assembled in the place which stores a seedling box. In this assembly, since the scaffold 1 is formed by three members, that is, a pair of scaffolding struts 2 and a single scaffolding plate 3, these members are prepared and the scaffolding plate of one scaffolding strut 2 in an upright state. One anchoring bracket 6 of the scaffolding plate 3 is latched on the mounting portion 2a1, and then the other scaffolding column 2 of the other scaffolding column 2 in a state where the other anchoring bracket 6 of the scaffolding plate 3 is raised. Lock to the part 2a1. At this time, the scaffolding plate 3 and the horizontal column 2a of each scaffolding column 2 are locked in a state in which the U-shaped locking bracket 6 is fitted from above into the three surfaces of the square-shaped scaffolding plate mounting portion 2a1. The members 2, 2, 3 are assembled as a scaffold 1.

  Then, the pair of vertical struts 2 of the assembled scaffold 1 are held by hand, and as shown in FIGS. 7 and 8A, the locking metal fitting 5 of each vertical strut 2b is attached to one of the loading platforms 11 of the light truck 10. The upper end of the tilt 11a is locked from above. At this time, the locking metal fitting 5 is brought into contact with the cushioning material 11b made of rubber or the like fixed to the surface of the lift 11a of the loading platform 11. Thereby, as shown in FIG. 7, the scaffold 1 is attached to the outer surface side of the loading platform 11 of the light truck 10, and the scaffold plate 3 of the scaffold 1 is installed at a predetermined height position from the ground.

  In addition, the scaffold 1 attached to the loading platform 11 has, for example, an intermediate portion of each vertical column 2b abutting on a lower portion of the outer surface 11a of the loading platform 11 via the cushioning material 8, and a leg column 2d of each platform column 2. The ground plate 2d1 is in a state having a predetermined gap from the ground. In this state, when an operator gets on the scaffolding plate 3 of the scaffold 1 attached to the light truck 10, the grounding plate 2d1 of the leg support 2d moves downward with the weight of the operator and comes into contact with the ground. The operator can reach the top of the storage shelf 12 without tilting the front 2 greatly, and one person can easily and safely store the seedling box on the top of the storage shelf 12. .

  Next, when a predetermined number of seedling boxes are stored in the storage shelf 12, the scaffold 1 is removed from the loading platform 11. This removal is carried out by lifting the scaffold 1 upward and removing the locking bracket 5 of each vertical column 2b from the lift 11a of the loading platform 11, and this detached scaffold 1 is disassembled into three members, which are light trucks. It is mounted on 10 loading platforms 11. The disassembly at this time is performed by removing the locking bracket 6 of the scaffold plate 3 from the scaffold plate mounting portion 2a1 of each scaffold column 2.

  The scaffold 1 is transported to the field along with the storage shelf 12 by the light truck 10, reassembled in the same manner as described above in the field, and attached again to the lift 11 a of the loading platform 11 of the light truck 10. Using the scaffold plate 3 of the scaffold 1 attached to the loading platform 11 of the light truck 10, the seedling box stored in the storage shelf 12 is taken out by an operator and set on the rice transplanter. When rice planting is finished and the scaffold 1 is no longer used (for example, season off), the scaffold 1 is disassembled into three members, and each member is stored in the storage shelf 12 and stored, for example.

  That is, the scaffold 1 is composed of three members, that is, a pair of scaffold pillars 2 that can be assembled and disassembled and one scaffold plate 3, and the scaffold 1 can be attached to or detached from a predetermined lift 11 a of the loading platform 11 of the light truck 10. With this construction, a single worker can perform the operation of putting in and out the seedling box with respect to the storage shelf 12 on the loading platform 11 having a high height by using the scaffold 1.

  The method of assembling and transporting the scaffold 1 is not limited to the above example. For example, when the scaffold 1 is assembled, the scaffold 1 in a state where one scaffold column 2 is locked in advance with the lift 11 a of the loading platform 10. The scaffold plate 3 may be assembled to the support column 2, and then the other bracket support column 2 may be assembled to the scaffold plate 3 and the locking bracket 5 of the support column 2 may be locked to the tilt 11 a. Further, when the scaffold 1 is transported to the farm field, when there is a space on the loading platform 11 of the light truck 10, it can be mounted and transported on the loading platform 11 in an assembled state.

  As described above, according to the scaffold 1, the scaffolding plate of the horizontal strut 2 a of each scaffold strut 2 can be obtained by latching the retaining bracket 5 of the vertical strut 2 b of each scaffold strut 2 to the loading platform 11 of the light truck 10. Since the scaffolding 1 in which the locking brackets 6 at both ends of the scaffolding plate 3 are placed and locked on the mounting portion 2a1 is attached to the outer surface side of the loading platform 11 in a substantially horizontal state, the loading platform 11 outer surface side of the light truck 10 In addition, the scaffold 1 can be easily installed, and a seed box can be taken in and out of the storage shelf 12 on the loading platform 11 even by a single worker such as a farm housewife.

  In addition, since the scaffold 1 is composed of three members that can be assembled and disassembled, the scaffold 1 itself can be easily assembled and disassembled, and the platform 11 of the anchoring bracket 5 of the scaffold column 2 can be used. Since the scaffold 1 can be attached and detached by attaching / detaching to the tilt 11a, the attachment / detachment work of the scaffold 1 with respect to the light truck 10 can be easily performed. In particular, the pair of left and right scaffolding columns 2 are formed of aluminum square pipes, and the locking bracket 5 of the vertical column 2b is formed in a U-shape that can be locked to the upper end of the 11a. The weight of the support column 2 can be reduced, and the shape of the locking metal fitting 5 can be simplified, so that the attaching / detaching operation to the loading platform 11 can be performed more easily.

  Further, the scaffold plate 3 is formed of an aluminum plate 3a, and the locking bracket 6 to the scaffold column 2 is formed in a U shape corresponding to the square pipe shape of the column 2, so that the scaffold plate 3 The weight can be reduced, and the scaffold plate 3 and each scaffold column 2 can be assembled reliably and easily, for example, the scaffold plate 3 can be locked to each scaffold column 2 on three sides to obtain a stable locked state. be able to.

  In addition, since the leg strut 2d is extended (connected) in a substantially vertical state downward to the front end portion of the horizontal strut 2a of each scaffold strut 2, the scaffold strut 2 is attached to the loading platform 11 of the truck 10 on the scaffold plate 3 When an operator gets on, the grounding plate 2d1 at the lower end of the leg column 2d can be brought into contact with the ground, and the tilting of the platform column 11 of the light truck 10 can be prevented. A stable scaffold 1 can be installed on the outer surface side of the. Thus, by using the scaffold 1, it is possible to improve the efficiency and safety of taking in and out the seedling box with respect to the storage shelf 12.

  Further, since the anti-slip is integrally formed on the surface of the plate body 3a of the scaffold plate 3, it is possible to prevent the operator's foot from slipping and to further improve the safety of taking in and out the seedling box. In particular, the anti-slip of the scaffold plate 3 has ribs 3b protruding upward at the front and rear end edges and a large number of protrusions 3c protruding in a predetermined shape at the center, so that the ribs 3b It is possible to prevent the foot from slipping at the end, and the protrusion 3c can prevent the foot from slipping at the center portion, thereby preventing the foot of the worker from slipping more reliably. Even if it is, the safety | security of taking in / out of a seedling box can be improved further. Note that rainwater on the scaffold plate 3 is drained downward from the openings provided at both ends in the longitudinal direction of the plate body 3a and the side surfaces of the projections 3b.

  Furthermore, by using an aluminum square pipe for the scaffolding column 2 and using an aluminum plate 3a for the scaffolding plate 3, the rib 3b at the front end of the scaffolding plate 3 is brought into contact with the inclined column 2c. Since the movement of the scaffold plate 3 is restricted, it is not necessary to separately provide a member for preventing the movement, and the structure of the scaffold 1 can be simplified. Thus, the inexpensive scaffold 1 can be provided. It is possible to contribute to improving the efficiency of rice planting work. In addition, if a plurality of scaffold plates 3 having different lengths L are prepared, the usability of the scaffold 1 can be further improved.

  By the way, in the said embodiment, as shown in FIG.8 (b), the shock absorbing material 7, such as rubber | gum, adheres to the inner surface of the latching metal fitting 5 of the scaffolding support | pillar 2, and it buffers to the lift 11a of the loading platform 11 of the light truck 10. Even when the material 11b is not fixed, it is possible to prevent damage to the tilt 11a due to attachment or removal of the scaffold 1.

  9, 10, 11 and 14 show other embodiments of the scaffold 1 according to the present invention. Hereinafter, the same parts as those in the above embodiment will be described with the same reference numerals. The scaffold 1 shown in FIG. 9 is obtained by lowering the height H of the vertical strut 2b of each scaffold strut 2 and welding and fixing the inclined strut 2c between the upper end of the vertical strut 2b and the front end of the horizontal strut 2a. The scaffold 1 of this form is suitably used when the height of the lift 11a of the loading platform 11 of the truck 10 is relatively low, or when the scaffold 1 is directly attached to the loading platform 11 surface of the truck 10. Further, the scaffold 1 shown in FIG. 10 is obtained by omitting the leg support 2d in the scaffold 1 of the above-described embodiment. The scaffold 1 has a height of the lift 11a of the loading platform 11 of the truck 10 (the tilt width is small). Largely), it is preferably used when the vertical support 2b restricts the tilt of each scaffold support 2 to the front. Also in each of these scaffolds 1, it is possible to obtain substantially the same effects as the scaffold 1 of the above embodiment.

  Further, the scaffold 1 shown in FIG. 11 is configured such that the leg strut 2d can be adjusted in height. That is, as shown in FIG. 12, a height adjusting leg strut 2d2 is movably inserted into the lower end of the leg strut 2d as shown by the arrow b in FIG. 11, and the height adjusting leg strut 2d2 and the leg strut 2d are connected. It is locked by the pin 15 and the retaining ring 15a. At this time, a plurality (four in the figure) of holes 16 are formed at regular intervals (for example, about 10 mm) in the vertical direction on the opposite side surfaces of the lower end of the leg support 2d, and the height adjusting leg support 2d2 A single hole 17 is formed in the upper opposing side surfaces. Then, a pin 15 is inserted between a predetermined hole 16 of the leg support 2d and a hole 17 of the height adjusting leg support 2d2, and the retaining ring 15a is locked in the locking hole at the tip of the pin 15, thereby pin 15 Thus, the leg strut 2d and the height adjusting leg strut 2d2 are connected, and the height H1 of the leg strut 2d is adjusted to a predetermined value according to the hole 16 to be used. For example, a resin ground plate 2d1 is fitted and fixed to the lower end of the height adjusting leg support 2d2.

  In the scaffold 1 of this embodiment, in addition to substantially the same effect as the scaffold 1 of the above embodiment, the height H1 of the leg support 2d is set to a predetermined value by selecting the hole 16, for example, the scaffold 1 Is attached to the platform 11 of the light truck 10, and when the operator sinks on the scaffold plate 3 with the weight of the operator, the ground plate 2d1 of the leg support 2d comes into contact with the ground and the scaffold plate A more stable installation state can be obtained on the scaffold 1 such that 3 is maintained in a horizontal state. The connecting structure of the leg strut 2d and the height adjusting leg strut 2d2 is not limited to the configuration using the pin 15 and the retaining ring 15a shown in FIG. 12, but for example, as shown in FIG. It is also possible to connect the leg strut 2d and the height adjusting leg strut 2d2 in such a manner that the height can be adjusted by fixing the nut 19 to the outer surface side by welding and screwing the butterfly bolt 20 into the nut 19.

  Further, in the scaffold 1 shown in FIG. 14, a locking bracket 20 as a second column locking portion is directed in the same direction as the locking bracket 5 at a substantially intermediate position in the height direction of the vertical column 2 b of the scaffold column 2. Attached. The locking bracket 20 has a U-shaped cross section and is formed in substantially the same shape as the locking bracket 5. The mounting portion 20 a of the locking bracket 20 uses the mounting hole 23 provided in the vertical column 2 b and the bolt 21. The nut 22 is detachably attached to the vertical column 2b. At this time, the locking metal fitting 20 is attached below (or above) a predetermined dimension from the portion where the end of the inclined support 2c of the vertical support 2b is welded for attachment and removal.

  The scaffold 1 of this embodiment is attached to the loading platform 11 of the light truck 10 as shown in FIG. 15, for example. That is, the rear-side tilt 11a1 (or side-side tilt) that is pivotally attached to the rear surface of the loading platform 11 of the light truck 10 by the hinge 25 is brought down and hung downward. In this state, the rear-side tilt 11a1 and the loading platform 11 The locking metal fitting 20 of the vertical column 2b of the scaffold 1 is inserted from above and locked into a gap 24 formed between the rear end. At this time, the upper portion of the support column 2b (the locking metal fitting 5 portion) is extended above the loading platform 11. When the scaffold 1 is attached to the loading platform 11, an operator can get on and off the loading platform 11 via the scaffold plate 3, and when the worker gets on and off the loading platform 11, The upper part of the column 2b can be used as a handrail.

  By the way, in the above description, the scaffolding 1 is directly attached to the platform 11 by latching the latching bracket 20 in the gap 24 of the platform 11, but the latching brackets 5, 20 are provided above and below the vertical column 2 b of the scaffold 1.
