2. Description of the Related Art Conventionally, when a steel sheet is cut out of a coil at a coil center or the like, in order to prevent bending of the steel sheet, the steel sheet is placed and transported on a skid in which wooden timbers are combined in a grid. However, wooden skids are integrated and difficult to disassemble (separate), bulky, and difficult to transport, making it difficult to collect and reuse. Therefore, a skid 41 that can be disassembled (separated) and assembled and is easily transported has been proposed. FIG. 1 for the proposed skid 41
8 will be described. FIG. 18 shows the skid, and (a)
Is a front view, and (b) is a plan view. Skid 41 is 3
It consists of four skid members 42 and three connecting members 43. Both the skid member 42 and the connecting member 43 are square steel pipes. The connecting member 43 has a shorter length than the skid member 42. In the skid 41, three skid members 42 are arranged in parallel with the connecting member 43 on three connecting members 43 arranged in parallel. Two of the three skid members 42 are arranged at both ends of the connecting member 43, and the other one is arranged at the center of the connecting member 43. Both ends in the longitudinal direction of the skid member 42 are
Of the three connecting members 43 arranged in parallel with each other, the two connecting members 43 are arranged so as to project substantially the same length from the two outer connecting members 43. A wire hooking portion 44 is attached to the lower surface of the skid member 42 projecting from the connecting member 43. The skid member 42 and the connection member 43 are removably connected to each other by the restoring force of the elastic piece 46 at the intersection. Since the skid member 42 and the connecting member 43 are detachably connected, the disassembly and assembly of the skid 41 become easy, a large amount of the skid 41 can be carried, and the skid 41 can be collected and reused. .

[0003]

When the object A is placed on the skid 41 and lifted, the wire W
Are inserted along the lower surface from both ends of the skid member 42, and a wire hooking portion 44 attached to the lower surface of the skid member 42.
Is hung with a wire W. When the skid 41 on which the mounted object A is mounted is lifted, the mounted object A is bent downward in the longitudinal direction of the skid member 42 and the longitudinal direction of the connecting member 43 due to the weight of the mounted object A. FIG. 19 shows a state where the object is placed on the skid 41,
(A) is a front view before lifting, (b) is a front view after lifting. As shown in FIG.
Further, the connecting member 43 remains connected to the skid member 42 by the restoring force of the elastic piece 46. 20A and 20B show a state in which the object is placed on the skid. FIG. 20A is a side view before lifting, and FIG. 20B is a side view after lifting. FIG. 20 shows the bending generated in the longitudinal direction of the connecting member 43.
As shown in (b), the skid members 42 disposed at both ends of the connecting member 43 are displaced upward with respect to the central skid member 42. The skid member 42 and the connecting member 43 are connected by the restoring force of the elastic piece 46. However, the restoring force of the elastic piece 46 is weak, and the connecting member 43 is not deformed while being straight. Therefore, a clearance (gap) is generated between the lower surface of the skid member 42 and the upper surface of the connecting member 43 in the connecting portion. For this reason, there is a problem that when the object A is placed on the skid 41 and lifted, the connecting member 43 is detached from the skid member 42.

[0004] The present invention has been made to solve the above-mentioned conventional drawbacks, and an object of the present invention is to provide a skid capable of safely transporting a skid on which a load is placed. is there.

[0013]

Next, a specific embodiment of the skid 1 of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a skid 1 according to a first embodiment, wherein (a) is a plan view and (b) is a front view. The skid 1 is formed by combining a plurality of bar members S in a lattice shape. In this case, the bar members S have two types having different lengths, and the lengths are large. A crosspiece S is called a skid member 2 and a crosspiece S whose length is small is called a connecting member 3. In this case, three skid members 2 and three connecting members 3 are used. Both are square steel pipes. In the skid 1, three skid members 2 are arranged in parallel with the connection member 3 on three connection members 3 arranged in parallel. Two of the three skid members 2 are arranged at both ends of the connecting member 3, and the other one is arranged at the center of the connecting member 3. Both ends of the skid member 2 in the longitudinal direction project from two outer members of the connecting member 3. A wire hook 4 is attached to the lower surface of the protruding portion of the skid member 2.

At the intersection of the skid member 2 and the connecting member 3, a receiving portion 5 and a spring 6 are attached to the lower surface of the skid member 2. The receiving portion 5 has an inverted L-shaped cross section, and the upper surface is fixed to the lower surface of the skid member 2 by welding or the like. The side surface of the connecting member 3 contacts the side surface of the receiving portion 5. The spring 6 is provided as a pair with the receiving portion 5. The spring 6 has a mounting portion for fixing to the lower surface of the skid member 2, a first inclined portion sequentially approaching the receiving portion side downward from the end of the mounting portion, and a receiving portion sequentially downward from the end of the first inclined portion. And a second inclined portion 6a separated from the portion. Receiving part 5
The connecting member 3 is fitted between the side surface of the spring and the spring 6. When the connecting member 3 is fitted between the receiving portion 5 and the spring 6, the spring 6 expands, and a restoring force is generated in the spring 6. The connecting member 3 is pressed against the side surface of the receiving portion 5 by the restoring force generated by the spring 6, and the skid member 2 and the connecting member 3 are detachably connected.

The skid 1 is composed of upper and lower cross members S
.. Is provided with a suspending means T for restricting the separation. In this case, the suspension means T includes a detachment preventing member 7 provided on each outer surface of the skid member 2 disposed outside. The detachment preventing members 7 are inserted into the openings at both ends of the connecting member 3 from the outside to the inside, and hold the connecting member 3 to the skid member 2. Since all six detachment prevention members 7 attached to the skid member 2 have the same shape, one of the detachment prevention members 7 will be described in detail.

FIGS. 2A and 2B show the skid 1 of the first embodiment, wherein FIG. 2A is a side view of a main part, and FIG.
The detachment preventing member 7 is arranged between the receiving portion 5 attached to the lower surface of the skid member 2 and the spring 6, and has a width smaller than the inner width of the opening of the connecting member 3. The detachment preventing member 7 is formed by bending a cross section into a substantially rectangular shape. The detachment preventing member 7 is fixed to the outer side surface of the skid member 2 by welding or the like, extends downward along the outer side surface of the skid member 2, protrudes from the lower surface of the skid member 2, bends from the lower end thereof, and is inclined. It extends downward and inward. The portion extending obliquely downward and inward forms the insertion portion 8. The inclination of the insertion portion 8 from the lower surface of the skid member 2 is set to, for example, about 5 ° to 20 °. As shown in FIG. 2B, the insertion portion 8 is inserted from the outer side surface of the skid member 2.
Is set shorter than the width Q of the skid member 2, whereby a part of the lower surface of the skid member 2 is exposed downward to form the lower surface exposed portion 12.

The assembling operation of the skid 1 will be described.
First, the assembling work of the center skid member 2 and the connecting member 3 will be described. The three connecting members 3 are arranged in parallel. The skid member 2 is lowered onto the connecting member 3 from above the center of the connecting member 3 at right angles to the connecting member 3. The connecting member 3 is fitted between the receiving portion 5 attached to the lower surface of the skid member 2 and the spring 6, and the lower surface of the skid member 2 is connected to the connecting member 3.
The center skid member 2 by contacting the upper surface of the
And the connecting member 3 can be assembled. At this time, the second inclined portion 6a of the spring 6 serves as a guide, so that the skid member 2 and the connecting member 3 can be easily assembled.

Next, the assembling work of the skid member 2 and the connecting member 3 arranged outside will be described. The assembling work of the skid member 2 and the connecting member 3 arranged on the outside includes a first assembling work of fitting the connecting member 3 between the receiving portion 5 and the spring 6, and a second assembling work of pushing the skid member inward. It is divided into two tasks. The skid member 2 and the connecting member 3 arranged on the outside are connected and assembled at a total of six locations, but since all have the same connecting structure, only one of the six locations will be described in detail. 3A and 3B show a method of assembling the skid 1 according to the first embodiment, wherein FIG. 3A is a side view of a main part at the end of the first assembling work, and FIG. .

First, the first assembling operation will be described. The skid member 2 arranged outside is brought above the end of the connecting member 3. The skid member 2 is lowered onto the connecting member 3 by aligning the lower surface exposed portion 12 of the skid member 2 with the upper surface of the end of the connecting member 3. The connecting member 3 is fitted between the receiving portion 5 attached to the lower surface of the skid member 2 and the spring 6 so that the lower surface exposed portion 12 of the skid member 2 comes into contact with the upper surface of the end of the connecting member 3, and the skid member 2 for connecting member 3
Place it temporarily on At this time, the insertion portion 8 of the separation preventing member 7 protrudes from the end of the connecting member 3. (FIG. 3
(A)).

Next, the second assembling operation will be described. The skid member 2 is pushed inward while the skid member 2 is temporarily placed on the connecting member 3. Detachment prevention member 7
Of the connecting member 3 is inserted inward from the end opening of the connecting member 3. The end of the connecting member 3 abuts on the inner surface of the separation preventing member 7 protruding from the lower surface of the skid member 2, and the skid member 2 and the connecting member 3 can be assembled (FIG. 3).
(B)).

Here, the work of disassembling (separating) the skid 1 will be described. Connecting member 3 of assembled skid 1
Is applied to the skid member 2 while restraining the skid member from moving. While the connecting member 3 is fitted between the receiving portion 5 attached to the lower surface of the skid member 2 and the spring 6, the spring 6 presses the side surface of the connecting member 3 and the skid member 2 comes out outward. Then, the insertion portion 8 of the separation preventing member 7 that has been inserted inside the connecting member 3 also comes out. Further, when an external force is applied to the skid member 2, the connecting member 3 comes out from between the receiving portion 5 and the spring 6, and the skid member 2 and the connecting member 3 can be disassembled.

In the present invention, the horizontal length P from the outer side surface of the skid member 2 to the distal end of the insertion portion 8 of the separation preventing member 7 can be the same as the width Q of the skid member 2. In this case, there is an advantage that the contact area between the insertion portion 8 and the connecting member 3 is increased, and the connection between the skid member 2 and the connecting member 3 is strengthened. However, the lower surface exposed portion 12 of the skid member 2 is lost, and the skid member 2 cannot be temporarily placed on the connecting member 3. For this reason, the assembling work of the skid member 2 and the connecting member 3 arranged on the outside,
There is a disadvantage that the operation of fitting the connecting member 3 between the receiving portion 5 and the spring 6 and the operation of pushing the skid member 2 inward must be performed simultaneously.

A description will be given of a case where the operation of fitting the connecting member 3 between the receiving portion 5 and the spring 6 and the operation of pushing the skid member 2 inward are performed simultaneously. First, the skid member 2 is brought outside the end of the connecting member 3. Connecting member 3
The skid member 2 is lifted so that the height of the gap formed between the lower surface of the skid member 2 and the insertion portion 8 of the separation preventing member 7 matches the height of the upper portion of the end opening of the skid member 2 and the height of the skid member 2 is increased. Hold. Next, while keeping the height of the skid member 2, the skid member 2 is moved closer to the connecting member 3 horizontally. Then, while the connecting member 3 is fitted between the receiving portion 5 attached to the lower surface of the skid member 2 and the spring 6, the end opening of the connecting member 3 is formed in the gap formed by the lower surface of the skid member 2 and the insertion portion 8. The upper part of the must be inserted.

For this reason, it is difficult to simultaneously perform the operation of fitting the connecting member 3 between the receiving portion 5 and the spring 6 and the operation of pushing the skid member 2 inward, and assembling the skid member 2 and the connecting member 3. Work becomes difficult.

On the other hand, in the skid 1 of the first embodiment shown in FIG. 3, the work of fitting the connecting member 3 between the receiving portion 5 and the spring 6 and the work of pushing the skid member 2 inward are divided. By doing so, the connection member 3 can be fitted between the receiving portion 5 and the spring 6 simply by lowering the skid member 2 onto the connection member 3 from above the end of the connection member 3. In addition, the lower surface exposed portion 12 of the skid member 2 comes into contact with the upper surface of the end of the connecting member 3, the position in the height direction of the skid member 2 is determined, and the skid member 2 is temporarily placed on the connecting member 3. For this reason, it is not necessary to match the height of the gap formed between the lower surface of the skid member 2 and the insertion portion 8 with the height of the upper portion of the end opening of the connecting member 3, and the skid member 2 is lifted and the height is raised. It is no longer necessary to fit the connecting member 3 between the receiving portion 5 and the spring 6 from outside the both ends of the connecting member 3 while holding the same. And the connecting member 3 can be assembled. Therefore, the width Q of the skid member 2 depends on the weight of the object A placed on the skid.
, The horizontal length P from the outer side surface of the skid member 2 to the tip of the insertion portion 8 can be set optimally.

The insertion portion 8 of the separation preventing member 7 is inserted into the connection member 3 by applying a force to the skid member 2 to move the connection member 3 toward the inside. At this time, since the insertion portion 8 is inclined obliquely downward and inward, it serves as a guide, and the insertion portion 8 can be easily inserted into the connection member 3. When the inclination of the insertion portion 8 from the lower surface of the skid member is small, the skid member 2
It is difficult to assemble with the connecting member 3, but the connecting force increases. Conversely, if the inclination is large, the assembling becomes easier, but the connecting force becomes weaker. Usually, the inclination is set to 10 °, but the object A
The weight can be set to an optimum inclination between 5 ° and 20 °. That is, the inclination and the length P are:
The optimal size can be set based on the weight of the mounted object A and the like. In addition, the skid member 2 can be easily positioned in the width direction by bringing the upper end of the end opening of the connecting member 3 into contact with the inner side surface of the separation preventing member 7 protruding from the lower surface of the skid member 2. .

When the connecting member 3 is fitted between the receiving portion 5 attached to the lower surface of the skid member 2 and the spring 6, the spring 6
The second inclined portion 6a is spread downward in a C shape, and can be easily fitted. Also, the skid member 2 and the connecting member 3 are connected by the restoring force of the spring 6,
Disassembly and assembly can be easily performed.

The skid member 2 and the connecting member 3 arranged on the outside are connected to each other so that the lower surface exposed portion 12 of the skid member 2 rests on the upper surface of the end of the connecting member 3.
The connection member 3 can be fitted between the receiving part 5 and the spring 6 simply by lowering the skid member 2 from above.
It rests on the connecting member 3. By mounting the skid member 2 on the connecting member 3, the height of the skid member 2 is determined, and the skid member 2 and the connecting member 3 can be assembled simply by applying an inward force to the skid member 2 and pushing it. For this reason, the assembling work of the skid member 2 and the connecting member 3 arranged outside is divided into a work of fitting the connecting member 3 between the receiving portion 5 and the spring 6 and a work of pushing the skid member 2 inward. As a result, the skid member 2 and the connecting member 3 can be easily assembled. At this time, the tip of the insertion portion 8 is lowered, and the insertion portion 8 can be easily inserted inside the connecting member 3. Further, at this time, the position of the skid member 2 in the width direction can be easily determined by applying the upper end of the opening of the connecting member 3 to the inner side surface of the separation preventing member 7. That is, in the skid 1 shown in FIG. 2 and the like, a part of the inner side surface of the detachment preventing member 7 that comes into contact with the upper end of the opening of the connecting member 3 constitutes a positioning means B for restricting the reduction of the interval between the cross members. .

An object A is placed on the assembled skid 1, a wire W is inserted from both ends of the skid member 2 along the lower surface, and the wire A is inserted into a wire hooking portion 4 attached to the lower surface of the skid member 2. Lift the skid 1 with W. When the skid 1 on which the object A is placed is lifted, the object A undergoes a downward bending in the longitudinal direction of the skid member 2 and the longitudinal direction of the connecting member 3 due to the weight of the object A. I do.

The change of the skid member 2 and the connecting member 3 with respect to the bending generated in the longitudinal direction of the connecting member 3 will be described with reference to FIG. FIG. 4 shows the skid 1 on which the object A is placed, (a) is a side view before lifting, (b)
FIG. 3 is a side view after lifting. When the skid 1 is lifted, as shown in FIG.
In contrast, the outer skid member 2 is displaced upward. When the skid member 2 disposed on the outside is displaced upward, the insertion portion 8 of the separation preventing member 7 is hooked on the upper inner surface of the opening at both ends of the connection member 3, and the connection between the skid member 2 and the connection member 3 is established. Maintained, both ends of the connecting member 3 are displaced together with the skid member 2 to prevent separation of the upper and lower cross members S, that is, the detachment of the connecting member 3 from the skid member 2. Further, the bending generated in the longitudinal direction of the connecting member 3 can be reduced by the strength of the connecting member 3.

Next, the skid 1 of the second embodiment shown in FIG. 5 will be described.

In the skid 1 of this embodiment, since all nine intersections have almost the same structure, only one intersection will be described in detail.

FIGS. 5A and 5B show the skid 1 of the second embodiment, wherein FIG. 5A is a side view of a main part, and FIG. 5B is a sectional view of a main part.
The receiving member 13 is attached to the connecting member 3 along the side surface inside the skid member 2. Receiving member 13
Project from one side surface of the connecting member 3. The receiving member 13 is formed of a metal fitting having a substantially L-shaped cross section, and includes a first piece 14 extending horizontally and a second piece 15 extending vertically upward. The first piece 14 of the receiving member 13 is fixed to the upper surface of the connecting member 3 by welding or the like. The side surface of the skid member 2 contacts the second piece 15 of the receiving member 13. A detachment preventing member 7 is attached to the skid member 2 on the opposite side of the receiving portion 5 with the connecting member 3 interposed therebetween, and the connecting member 3 fits between the receiving portion 5 and the detachment preventing member 7. The detachment prevention member 7 extends to the lower side of the first piece 14 of the receiving member 13 along the side surface of the connecting member 3. The detachment preventing member 7 is formed by bending a cross section along the connecting member 3 into a substantially rectangular shape, and extends horizontally along the lower surface of the skid member 2 toward the receiving member. 9 has an insertion portion 8 that is recessed downward from the end portion and extends horizontally below the first piece 14 of the receiving member 13. The upper surface of the mounting portion 9 is fixed to the lower surface of the skid member 2 by welding or the like. A gap is formed between the upper surface of the insertion section 8 and the first piece 14. The length of the insertion portion 8 from the inner surface of the skid member 2 is shorter than the width of the skid member 2.

Next, the assembling work of the skid 1 of this embodiment will be described. In the skid 1 of this embodiment,
There are a total of 9 intersections. Of these, three intersections of the central skid member 2 and the connecting member 3 and the skid 1
Member 2 and connecting member 3 arranged outside one of
And the three intersections have the same connection structure, and the connection structure of the three intersections of the skid member 2 and the connection member 3 arranged outside the other side of the skid 1 has a different relationship. . Therefore, the connection structure of one of the nine intersections will be described.

FIGS. 6A and 6B show a method of assembling the skid 1 according to the second embodiment. FIG. 6A is a side view of a main part at the end of the first assembling operation, and FIG. It is a part side view.

First, the skid member 2 is lowered from above the connecting member 3, and the receiving portion 5 of the skid member 2 and the separation preventing member 7 are removed.
The skid member 2 is placed on the connecting member 3 and the receiving portion 5 is brought into contact with the side surface of the connecting member 3 (FIG. 6A).

Next, the skid member 2 is pushed into the receiving member side, and the insertion portion 8 of the separation preventing member 7 is received by the first member 13 of the receiving member 13.
The skid member 2 and the connecting member 3 are assembled by inserting the side surface of the skid member 2 into contact with the second piece 15 of the receiving member 13 by inserting the side surface of the skid member 2 below (FIG. 6A).
Note that the assembled skid 1 can be easily disassembled by performing the above-described assembling operation in reverse.

The assembling operation of the skid 1 is divided into the operation of fitting the connecting member 3 between the receiving portion 5 and the separation preventing member 7 and the operation of pushing the skid member 2 toward the receiving member. 2 and the connecting member 3 can be easily assembled. At this time, the insertion portion 8 of the separation prevention member 7
The insertion portion 8 can be easily inserted under the first piece 14 by a gap formed between the upper surface of the first piece 14 and the first piece 14 of the receiving member 13. At this time, the second piece 15
To the side surface of the skid member 2. Skid member 2
Can be easily determined in the width direction.

As described above, in the skid 1 shown in FIG.
The suspension means T is constituted by the receiving member 13 and the separation preventing member 7 and the like, and the positioning means B is constituted by the receiving member 13 and the like.

That is, when the skid member 2 is to be vertically separated from the skid member 2 by the suspension means T, the receiving member 1 attached to the connection member 3
3, the lower surface of the first piece 14 is hooked on the upper surface of the insertion portion 8 of the disengagement prevention member 7 attached to the skid member 2, and the connecting member 3 is hung by the skid member 2, and the connection between the skid member 2 and the connecting member 3 is established. To maintain. With positioning means B,
The position of the skid member 2 in the width direction can be determined.

Since the suspending means T is provided at all the nine intersections of the skid 1, the vertical movement of the skid member 2 or one of the connecting members 3 at the intersections is prevented. The other member is displaced following the vertical direction, and the connection between the skid member 2 and the connecting member 3 is maintained. Hereinafter, a case where the object A is placed on the assembled skid and the skid 1 is lifted by the wire W and a case where the skid 1 is lifted by the forklift will be specifically described.

First, the case where the skid 1 is lifted by the wire W will be described. Skid 1 on which object A is placed
When the object A is lifted, the object A undergoes downward bending in the longitudinal direction of the skid member 2 and the longitudinal direction of the connecting member 3 due to the weight of the object A.

Basically, the skid member 2 and the connecting member 3 are connected at their intersections by means of suspending means T, and the connecting member 3 is suspended by the skid member 2. For this reason, the connecting member 3 is suspended by the skid member 2 and does not fall down against the vertical deflection in the longitudinal direction of the skid member 2.

In particular, with respect to the downwardly protruding bending generated in the longitudinal direction of the connecting member 3, the skid member 2 disposed outside is displaced upward with respect to the central skid member 2. Conventionally, the skid member 2 and the connecting member 3 are
6, the connecting force is weak, the connecting member 3 is not deformed while being straight, and a gap is generated between the skid member 2 and the connecting member 3 at both ends of the connecting member 3, and the connection is performed. The member 3 was separated from the skid member 2.

In the skid 1 of this embodiment, the skid member 2 and the connecting member 3 are connected by the suspending means T, so that the connection between the skid member 2 and the connecting member 3 arranged outside is maintained and the connecting member is maintained. 3 are skid members 2
Together with the connecting member 3, and the connecting member 3 is bent downward to protrude, thereby preventing the connecting member 3 from being detached from the skid member 2.

Next, a case where the forklift is lifted will be described. To lift the skid 1 with a forklift, forklift claws are inserted from both sides of the skid 1 into both sides of the central connecting member 3, and the claws are lifted to lift the skid 1. When the skid 1 is lifted, the mounted object A is bent upward in the longitudinal direction of the skid member 2 due to the weight of the mounted object A. In addition, when the forklift claw does not reach the innermost skid member 2 due to the length of the forklift claw, the mounted object A is bent downward by the weight of the mounted object A.

For the upwardly projecting flexure occurring in the longitudinal direction of the skid member 2, the connecting member 3
Hangs on and does not fall.

In particular, a force is applied to the skid 1 to push down the back side of the skid 1 with respect to the bending of the mounted object A at the back side. In the skid of the first embodiment, since the skid member 2 and the connecting member 3 are connected by the restoring force of the elastic piece 46, the connecting force is weak, and the skid member 2 and the connecting member 3 are connected.
The skid member 2 on the back side with the intersection on the front side as the fulcrum
At the same time, the connecting member 3 rotates downward, and a gap is formed between the skid member 2 and the connecting member 3 at the center intersection, and the connecting member 3 is separated from the skid 1 together with the skid member 2 on the far side. Was.

In the skid 1 shown in FIG. 5, the skid member 2 and the connecting member 3 are connected by the suspending means T, and the connection is maintained at the intersection of the skid member 2 and the connecting member 3 at the center. , The connecting member 3 is supported by the skid member 2, and at the intersection on the near side, the connecting member 3
Abuts on the skid member 2, and the connecting member 3 is fixed, and the connecting member 3 forms a cantilever projecting from the center intersection to the back side.

As a result, the connecting member 3 receives the force of pushing down the rear side of the skid 1 by the mounted object A via the rear side skid member 2, and the connecting member 3 is detached from the skid 1 together with the rear side skid member 2. Is prevented.
