Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to work tables, display stands, stages and other pedestals used in various fields such as temporary sites and gardening, and particularly to pedestals that can be folded and transported / stored when not necessary. It is.
[0002]
[Prior art]
There are pedestals that are used as work tables in various fields such as building construction sites and gardening. These pedestals are generally not easily installed in a single place, such as when not used or moved to a necessary place, and can be easily folded. This is because it is required to be easily transported and moved to the place of use, easily installed, and not bulky for unnecessary storage.
[0003]
As such a foldable base, a base as shown in FIG. 7 is used. The figure shows that the base ends of the ladders b and b, which are legs, are pivotally attached to the left and right ends of the deck a on which the operator rides, respectively. And open left and right. Thereafter, the connecting members c and c rotatably attached to the intermediate portions of the ladders b and b are hooked on the intermediate portions of the deck a to fix and support the ladders b and b.
[0004]
[Problems to be solved by the invention]
The problem with such a pedestal is that the legs b and b are not sufficiently fixed and the legs b and b are unstable. That is, the leg portions b and b are simply connected by the connecting members c and c extending from the intermediate portion to the intermediate portion of the deck a, and the lower portions of the leg portions b and b do not support anything. Further, since there is no connection between the left and right leg parts b and b, the structure of the entire pedestal cannot be said to be integrated, which is insufficient as a support structure. When an operator rides on such a pedestal, the support portion is unstable and cannot be supported firmly, and the pedestal is a factor that causes the worker to feel great anxiety. Also, the pedestal fluttering could lead to a major accident.
[0005]
Another problem with these pedestals is to easily open the pedestal so that it stands or folds easily. When the pedestal is erected, the more complicated the member for fixing the legs, the more difficult the stance and folding work is, and the complicated work results in a large loss of work time.
[0006]
This invention was made to solve the above problems, the support structure of the legs is very solid, it is difficult to cause a flutter, and does not give anxiety to the riding worker, An object of the present invention is to provide a folding base that is easy to stand and fold.
[0007]
[Means for Solving the Problems]
The folding pedestal according to the present invention crosses diagonal materials like left and right legs that can be opened and closed with the connecting portion as a fulcrum, so that the diagonal materials cross when the legs are opened. The left and right legs are supported in a staking state.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The folding pedestal according to the present invention is a pedestal that can be folded by opening and closing, and supports the legs firmly by crossing diagonal materials between the left and right leg portions in a bracing manner. The base ends of the left and right legs are pivotally attached to the left and right ends of the deck on which an operator or the like rides, and the pedestal is erected by pushing open to the left and right. A diagonal material is stretched across the base end of the left or right leg and the distal end of the other leg. One of the diagonal members is attached at one end to the base end side of the leg, and the other end is attached to the tip end side of the leg. Similarly, an oblique material is straddled between the proximal end portion on either the left or right side and the distal end portion of the other leg portion so that the two oblique materials cross each other.
[0009]
In this way, by crossing two diagonal materials like staking, the stability of the pedestal is remarkably increased, and the fluttering is remarkably reduced. The diagonal material is not necessarily a straight member having a full length, and for example, one end side may be bifurcated, and the bifurcated distal end of the diagonal material is connected to the proximal end side or the distal end side of the leg portion. By doing so, it is possible to suppress the shake of the pedestal. By fixing the intersection of the two diagonal members, it is possible to better suppress the blurring of the legs.
[0010]
The two diagonal members can be folded with one touch by closing the legs. As described above, the left and right legs are pivotally attached to the left and right ends of the deck, and the diagonal material spanned from the base end side of one leg to the tip end side of the other leg is an intermediate shaft. A diagonal material that bends with a stop as a fulcrum. Both ends of the bending member are rotatable with respect to the leg portions. The connecting diagonal member that crosses the bent diagonal member is connected to the intersection of the bent diagonal member so as to be movable in the longitudinal direction of the bent diagonal member and to the end of the opposite leg. It can be fixed to be diagonally continuous with the material. Both the connecting diagonal member and the connecting diagonal member are rotatably connected to the leg side. Any one of the bent diagonal member, the connecting diagonal member, and the connecting diagonal member may have a bifurcated tip, and may be connected to the leg portion so as to be rotatable at two points.
[0011]
With such a pedestal, when the leg is pushed open to the left and right, the bent diagonal will automatically rotate and the shaft will rotate, and the connecting diagonal will be connected to the bent diagonal. Moves and both cross. The pedestal standing work is completed only by connecting the connecting diagonal member and the connecting diagonal member. In the case of folding, it is possible to close and fold the leg portion by separating either the connecting diagonal member or the connecting diagonal member. Since at least one end of the diagonal member has a bifurcated shape, the bifurcated two points are connected to the leg portion, and the pedestal in the width direction can also be prevented.
[0012]
【Example】
Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings. The pedestal of the example is made of steel in consideration of the strength of each part. 1 and 2, reference numeral 1 denotes a deck, which is a steel frame in which a number of holes are punched and a steel plate stretched out is used. Two pairs of leg portions 2 are attached to the left and right sides of the deck 1 so as to be openable and closable. In the embodiment, the two round pipes are formed in a substantially U shape by bending the middle part, respectively, and have a left leg part 2a, 2a and a right leg part 2b, 2b. The base end portions of these leg portions 2a and 2b, that is, the bent intermediate portions are rotatably attached to the deck 1 by the bracket 3, and the left and right leg portions 2a and 2b can be folded and opened with respect to the deck 1. It is possible. Middle rails 4a and 4b made of round pipes are provided at the ends of the pair of leg portions 2a and 2a or 2b and 2b, that is, near the landing side. A caster 5 with a brake is attached to the tip of the leg 2a or 2b on either the left or right side. The reason why the casters 5 are not attached to all of the legs 2a and 2b is to suppress the grazing caused by the casters 5 as much as possible.
[0013]
The diagonal members 12, 14, and 16 can be automatically extended and folded simultaneously with the opening and closing of the leg portions 2a and 2b. One end of the bent diagonal member 12 is rotatably attached to the base end portion of the leg portion 2a on the one side. A shaft 13 is fixed at an intermediate portion of the bent diagonal member 12 and can be bent with the pin 13 as a fulcrum. The other end of the bent diagonal member 12 is rotatably attached to the middle rail 4b of the other leg 2b.
[0014]
A connecting diagonal member 14 is rotatable at the base end of the other leg 2b, and an intermediate portion thereof is connected to an intermediate portion of the bent diagonal member 12 and moves in the longitudinal direction of the bent diagonal member 12. It is possible. That is, as shown in FIG. 5, the hook member 15 is rotatably attached to the side surface of the connecting diagonal member 14, and the hook member 15 is hooked on the bent diagonal member 12 and can move in the longitudinal direction. That is, the intersection of the connecting diagonal member 14 and the bent diagonal member 12 is movable in the longitudinal direction of the bent diagonal member 12. A bifurcated connecting diagonal member 16 as shown in FIG. 6 is attached to the middle rail 4 b of the leg 2 a and can be connected to the connecting diagonal member 14 by the pin 8, the cylinder 9 and the hook 10.
[0015]
The case where the folding base as described above is set up will be described. When the leg portions 2a and 2b are opened with respect to the deck 1, the bent slanting material 12 rotates with the pin 13 as a fulcrum according to this and extends on a straight line. Accordingly, the hooking member 15 of the connecting diagonal member 14 moves, and the connecting diagonal member 14 also moves in the middle direction of the bent diagonal member 12, with the left and right leg portions 2a and 2b fully opened. The bent diagonal member 12 is straightened, and the intersection with the connecting diagonal member 14 is fixed without moving any more. In this state, the connecting diagonal member 16 is tilted so as to be in line with the inclination of the connecting diagonal member 14, the hook 10 is hooked on the pin 8 of the connecting diagonal member 14, and the tube 9 is covered and fixed. When the pedestal is folded, the above work may be reversed.
[0016]
As described above, the diagonal members 12, 14, and 16 are crossed and hung on the left and right legs 2a and 2b, and the crossed portions are fixed, so that the grabbing of both ends 2a and 2b is suppressed. , Do not worry the worker. Further, if the end of any of the diagonal members 12, 14, 16 is bifurcated, it is connected to the leg portions 2a, 2b at two points, so that the width direction of the pedestal, that is, the diagonal materials 12, 14 is obtained.・ Grasping in the direction perpendicular to 16 can be suppressed.
[0017]
In the embodiment, only the lower end portion of one diagonal member has a bifurcated shape. However, either or all of the diagonal material has a bifurcated shape, and the base end portion or the distal end portion of the leg portions 2a and 2b is formed at two points. It is also possible to suppress the movement in the direction perpendicular to the diagonal material by connecting them, and this does not prevent the plurality of ends from being bifurcated.
[0018]
【The invention's effect】
The present invention has the above-described configuration and can obtain the following effects.
* By crossing and hanging diagonal materials between the left and right legs, it is possible to suppress the left and right legs from grabbing, and as a stable pedestal, the operator does not feel uneasy.
* By making the tip of any diagonal material into a bifurcated shape and connecting it to the base end or the distal end of the leg at two points, it is possible to hold down the pedestal in the direction perpendicular to the diagonal material, and work more Does not give anxiety to the person
* By simply opening or closing the legs to both sides, the bent and connected diagonal materials automatically move diagonally to support the legs, so the pedestal can be erected and folded with a single touch for quick work. Is possible.
* Because the diagonal member is composed of a bent diagonal member, a connecting diagonal member and a connected diagonal member, the diagonal member can be folded or divided when the legs are folded, so that the folded size can be reduced.
* By using parts instead of aluminum, damage and wear are reduced, and maintenance costs can be reduced.
