FIG. 24A is an exploded perspective view showing the transfer plate and the lock rod (holding member), and FIG. 24B is a perspective view showing a state where the lock rod is fixed to the transfer plate.
In FIG. 22, 1 is a table top plate, and 2 is a column (leg) attached to the top plate 1. A fixing portion 3 is fixed to the back surface of the top plate 1. As shown in FIGS. 22 and 23, the fixing portion 3 includes a base 31 having a predetermined thickness, a bottomed short cylindrical fitting protrusion 32 that is recessed toward the back surface (lower surface) in the center of the base 31, and It is composed of a horizontally long insertion hole 34 drilled in the center of the bottom 33 of the fitting protrusion 32. The bottom surface 33 of the fitting protrusion 32 is a spiral surface S that descends while being gently twisted and inclined in directions opposite to each other across the insertion hole 34, that is, in the directions of arrows Y and Y shown in FIG. , S.

On the other hand, a rotating part (fixed part) 4 is provided at the end of a column (leg part) 2 attached to the top plate 1. As shown in FIGS. 22 and 23, the rotating portion 4 has a predetermined thickness that is fixed in a bridging manner at a right angle to the inner peripheral surface at a position that is inward from the end of the support column 2 by a predetermined dimension. A passing plate 41 having an elliptical shape in plan view, a fitting hole 42 formed between the end portion of the support column 2 and the passing plate 41 and into which the fitting protrusion 32 of the base 31 is fitted, and the passing plate 41 It is comprised from the T-shaped lock stick | rod 43 standingly arranged in the center.
For example, as shown in FIGS. 22 and 24, the lock rod 43 is inserted into an insertion hole 411 drilled in the center of the transfer plate 41 so as to protrude from the back surface side of the transfer plate 41 to the front surface side. In addition, a vertical bar 432 made of a rivet or the like having a hemispherical head fixed to the back side of the transfer plate 41 by welding or the like, and a tip of the vertical bar 432 by welding or the like in a state orthogonal to the vertical bar 432 It is formed in a T shape by a horizontal locking rod 431 which is fixed and is inserted through a horizontally long insertion hole 34 drilled in the bottom surface 33 of the fitting projection 32.

In this state, when the support column 2 is rotated in the tightening direction, the locking rod 431 slides along the spiral surface S from the lower position to the higher position of the spiral surface S, and uses the screw tightening principle. As a result, the column 2 and the top plate 1 are firmly coupled and fixed as a result of being gradually tightened with respect to the spiral surface S (see FIG. 22).
On the other hand, when removing the support | pillar 2 from the top plate 1, it rotates in the direction which loosens the support | pillar 2 in the state which turned the top plate 1 upside down and was pressed. As a result, the fastening between the locking rod 431 and the spiral surface S is released, and when the locking rod 431 is rotated to a position that matches the horizontally long insertion hole 34, the locked state between the support column 2 and the base 31 is released. As a result, the column 2 can be easily detached from the top plate 1.

Japanese Patent No. 3474265

However, the conventional support structure has the following problems. That is, the transfer plate constituting the rotating part is fixed to the inner peripheral surface of the support column by welding or the like at a position inside the support column by a predetermined dimension, but the transfer plate has an elliptical shape. Due to the relationship of the flat plate, the connecting plate is in contact with the inner peripheral surface of the support column only at the outer peripheral edge in the major axis direction. For this reason, it is difficult to maintain a horizontal state when fixed by welding or the like, and the transfer plate is often fixed obliquely with respect to the inner peripheral surface of the support column. In such a case, since the T-shaped lock rod erected on the transfer plate is naturally inclined, there is a problem that the column can not be attached to the top plate satisfactorily.

In addition, the T-shaped lock rod slides from the lower position to the higher position of the spiral surface along the spiral surface provided on the bottom surface of the mating protrusion by rotating the support column in the tightening direction. Therefore, a force to pull the transfer plate upward is applied to the transfer plate on which the lock rod is erected. However, since the transfer plate is fixed only to the outer peripheral edge in the major axis direction with respect to the inner peripheral surface of the end portion of the support column, when a force is applied to pull up the transfer plate as described above, When the thickness of the transfer plate is thin, there has been a problem that deformation such as warping upward occurs due to repeated use over a long period of time. Therefore, when deformation occurs in the transfer plate, it is necessary to return the original state by hitting the transfer plate, or to increase the plate thickness in order to prevent the transfer plate from being deformed. It was.

In view of the above-mentioned various problems, the present invention is such that the connecting plate constituting the rotating portion is attached obliquely to the inner peripheral surface of the support column, or warps upwards due to repeated use over a long period of time. It is an object of the present invention to provide a support structure that can prevent deformation.

In order to solve the above-described problems, the present invention provides a strut structure in which a rotating portion is fitted to a fixed portion, and a base that constitutes the fixed portion is fixed to a top plate and / or a bottom plate, and a short cylinder is attached to the base. And a through hole is formed in the bottom surface of the fitting protrusion, and spiral surfaces that are gently inclined are formed on both sides of the insertion hole. Attaching to the end of the support, bridging the transfer plate in the diametrical direction at the substantially end of the support, a T-shaped lock rod standing at the approximate center of the transfer plate, Is inserted into the inner periphery of the column in the rotating part, the locking rod of the T-shaped lock rod is inserted into the insertion hole in the bottom surface, and the column is rotated around the axis. As a result, while the locking rod is tightened to the spiral surface, Part is a post structure to be locked, provided with vertical supporting wall of a predetermined height on a part of the outer peripheral edge of the passing sheet, and be provided with reinforcing recesses of a predetermined shape on a predetermined position of the upper surface.
Further, instead of providing a reinforcing recess on the upper surface of the transfer plate, a reinforcing protrusion having a predetermined height may be provided vertically on the outer peripheral edge at a position that does not match the support wall of the transfer plate. You may make it provide both a recessed part and a reinforcement protrusion.
Furthermore, you may make it provide a support ring in the center part of the upper surface of the said board.

According to the support structure of the present invention, since a support wall having a predetermined height is provided vertically on a part of the outer peripheral edge of the transfer plate, when fixing the transfer plate to the inner peripheral surface of the support column, When the support wall comes into contact with the inner peripheral surface of the support column, the transfer plate is supported, and the transfer plate can be prevented from being obliquely fixed to the inner peripheral surface of the support column. As a result, the T-shaped lock rod fixed to the transfer plate is not inclined, so that there is no problem when the column is attached to the top plate or the like.
Further, since the reinforcing plate is provided with a reinforcing recess having a predetermined shape at a predetermined position on the upper surface, the rigidity of the transferring plate can be increased by the reinforcing recess and the supporting wall even when the thickness of the transferring plate is thin. . As a result, even when the thickness of the transfer plate is not particularly increased, when the column is attached to the top plate or the like, the transfer plate warps upward due to the force to pull the transfer plate upward. It is possible to prevent such deformation.

Furthermore, if a reinforcing protrusion having a predetermined height is provided vertically on the outer peripheral edge at a position that does not match the support wall of the transfer plate, the rigidity of the transfer plate can be increased by the reinforcing protrusion and the support wall. In addition, if a reinforcing recess is provided on the upper surface of the transfer plate together with the reinforcing protrusion, the rigidity of the transfer plate can be further increased by the synergistic effect of the reinforcing recess, the reinforcing protrusion and the support wall. Even when the thickness of the plate is thin, it is possible to prevent the transfer plate from being deformed such as being warped upward when the column is attached to the top plate or the like.

Further, if a support ring is provided at the center of the upper surface of the transfer plate, the support ring can increase the rigidity at the center of the transfer plate. That is, by providing the support ring, even when the thickness of the transfer plate is thin, it is possible to increase the rigidity of the entire transfer plate in combination with the presence of the reinforcing recess and / or the reinforcing protrusion and the support wall. It is possible to prevent the transfer plate from being deformed when the is attached to the top plate or the like. In addition, when the T-shaped lock rod is fixed to the transfer plate, the lock rod can be vertically supported by the support ring, and can be fixed with high accuracy in a state where it is prevented from tilting. Therefore, there is no trouble when the support is attached to the top plate or the like.

Hereinafter, embodiments for carrying out the present invention will be specifically described with reference to FIGS. 1 to 21. In the present invention, since only the structure of the transfer plate is different from the prior art, description of the detailed structure other than the transfer plate is omitted here. In the present invention, the same components as those in the prior art shown in FIGS. 22 to 24 will be described using the same reference numerals.

First, Embodiment 1 of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a transfer plate according to Embodiment 1 of the present invention. 2A is a developed view of the transfer plate shown in FIG. 1, FIG. 2B is a plan view of the transfer plate shown in FIG. 1, and FIG. 2C is a transfer taken along the line A1-A1 in FIG. FIG. 4D is a cross-sectional view of the connecting plate taken along line A2-A2 of FIG. FIG. 3A is an exploded perspective view illustrating the transfer plate and the lock rod according to the first embodiment, and FIG. 3B is a perspective view illustrating a state where the lock rod is fixed to the transfer plate. FIG. 4 is an enlarged cross-sectional view of a main part showing a state in which the transfer plate is fixed to the inner peripheral surface of the end portion of the column.

FIG. 1 shows a perspective view of a transfer plate 41A according to Embodiment 1 of the present invention. The transfer plate 41A is made of a metal plate having a predetermined thickness, and the plan view shape is elliptical as shown in FIGS. 2 (a) and 2 (b). As shown in FIGS. 1 and 2A, 2B, and 2D, a vertical bar 432 that constitutes one of the T-shaped lock bars 43 is inserted into the central portion of the transfer plate 41A. The insertion hole 41 A 1 is drilled with a slightly larger diameter than the vertical bar 432.

As shown in FIGS. 1, 2 (c), and (d), a support wall 41 A 2 U having a predetermined height faces upward on the outer peripheral edge in the major axis direction of the transfer plate 41 A that contacts the inner peripheral surface of the support column 2. It is provided vertically. The height of the support wall 41A2U is set to such an extent that it does not come into contact with the fitting protrusion 32 of the base 31 fitted in the fitting hole 42 provided in the end portion of the column 2 as shown in FIG. To do. For example, as shown in FIG. 2A, the support wall 41A2U has a longer length in the major axis direction of the transfer plate 41A by the length of the support wall 41A2U, and is longer in the longer axis direction of the transfer plate 41A. By bending the end portion upward by 90 ° at a predetermined position (position of the fold line L1 shown in FIG. 2A), it can be formed integrally with the transfer plate 41A.

As shown in FIGS. 1 and 2 (b) to (d), at the position between the outer peripheral edge in the short axis direction of the transfer plate 41A not in contact with the inner peripheral surface of the column 2 and the insertion hole 41A1, the transfer plate is provided. A linear reinforcing recess 41A3S having a predetermined width is provided along the long axis direction of 41A. As shown in FIGS. 1 and 2 (c) and 2 (d), the reinforcing recess 41A3S pressurizes a predetermined position on the upper surface of the transfer plate 41A so as to be recessed linearly by a predetermined dimension, and has a corresponding lower surface (back surface). ) Side is bulged.

The support wall 41A2U and the reinforcing recess 41A3S can be formed integrally with the transfer plate 41A, for example, by press-molding a flat transfer plate 41A having an insertion hole 41A1 in the center.

Next, when fixing the T-shaped lock rod 43 to the transfer plate 41A configured as described above, as shown in FIG. 3 (a), from below the transfer plate 41A, to the center of the transfer plate 41A. A vertical bar 432 made of rivets or the like is inserted into the drilled insertion hole 41A1, and in this state, the hemispherical head of the vertical bar 432 is fixed on the lower surface (back surface) side of the transfer plate 41A by welding or the like. Subsequently, the locking bar 431 is fixed to the tip of the vertical bar 432 protruding above the transfer plate 41A by welding or the like in a state orthogonal to the vertical bar 432, that is, in a horizontal state. At this time, as shown in FIG. 3B, for example, the locking bar 431 is fixed horizontally to the tip of the vertical bar 432 in a state parallel to the short axis direction of the transfer plate 41A. As described above, the T-shaped lock bar 43 including the vertical bar 432 and the locking bar 431 is fixed to the central portion of the transfer plate 41A as shown in FIG.

Subsequently, when the transfer plate 41A to which the T-shaped lock rod 43 is fixed as described above is fixed to the inner peripheral surface of the end portion of the support column 2, as shown in FIG. The upper end portion of the support wall 41A2U provided on the transfer plate 41A is fixed to the inner peripheral surface of the support column 2 by welding or the like at a position entering the inside by a predetermined dimension from the end portion. The fixing position of the transfer plate 41A with respect to the column 2 is below the lock rod 431 of the lock rod 43 inserted into the insertion hole 34 of the fitting protrusion 32 when the column 2 is fixed to the top plate 1. It is preferable that the end surface be positioned so as to barely protrude on the spiral surface S.

As described above, when fixing the transfer plate 41A to the inner peripheral surface of the end of the support column 2, the outer peripheral edge of the transfer plate 41A in the major axis direction, that is, the portion in contact with the inner peripheral surface of the end of the support column 2, Since the support wall 41A2U having a predetermined height is provided vertically upward, the transfer plate 41A is supported by the support wall 41A2U coming into contact with the inner peripheral surface of the support column 2 and is not inclined. It is possible to prevent the transfer plate 41 A from being obliquely fixed to the inner peripheral surface of the column 2. As a result, the T-shaped lock rod 43 fixed to the transfer plate 41A is not inclined, so that there is no trouble when the column 2 is attached to the top plate 1.

Further, a linear reinforcing recess 41A3S having a predetermined width is provided along the long axis direction at a position between the outer peripheral edge in the short axis direction of the transfer plate 41A and the insertion hole 41A1. Even when the plate thickness is thin, the rigidity of the transfer plate 41A can be increased by the reinforcing recess 41A3S and the support wall 41A2U. As a result, when the column 2 is attached to the top plate 1, the column 2 is rotated in the tightening direction, and the locking rod 431 is moved along the spiral surface S provided on the bottom surface 33 of the fitting projection 32. By sliding the spiral surface S from a low position toward a high position, even if a force for pulling the transfer plate 41A upward acts on the transfer plate 41A, the transfer plate 41A warps upward. It is possible to satisfactorily prevent the occurrence of such deformation.

In addition, about the structure of the transfer board 41A which concerns on Example 1, another embodiment can be considered. Hereinafter, a description will be given with reference to FIGS. 5A is a perspective view showing another embodiment of the transfer plate according to Example 1, FIG. 5B is a plan view of the transfer plate shown in FIG. 5A, and FIG. FIG. 4B is a cross-sectional view of the transfer plate taken along line B1-B1, and FIG. 4D is a cross-sectional view of the transfer plate taken along line B2-B2 of FIG. FIG. 6 is an enlarged cross-sectional view of a main part illustrating a state in which a transfer plate according to another embodiment of Example 1 is fixed to an inner peripheral surface of an end portion of a column. 7A and 7B are perspective views showing other embodiments of the transfer plate according to the first embodiment.

In the transfer plate 41A shown in FIG. 5, a support wall 41A2D having a predetermined height is provided vertically downward on the outer peripheral edge in the major axis direction, and the upper surface of the transfer plate 41A has an insertion hole 41A1. A circular reinforcing recess 41A3C having a predetermined width is provided concentrically with the insertion hole 41A1 at a position separated by a predetermined dimension in the radial direction (however, a position not exceeding the outer peripheral edge in the short axis direction).
Here, the support wall 41A2D and the reinforcement recess 41A3C can be provided in the same manner as the support wall 41A2U and the reinforcement recess 41A3S of the transfer plate 41A shown in FIGS. That is, the support wall 41A2D is, for example, as shown in FIG. 2A, the length in the major axis direction of the transfer plate 41A is increased by the length of the support wall 41A2D, and the longer direction of the transfer plate 41A is increased. Can be formed integrally with the transfer plate 41A by bending the end thereof at 90 ° downward at a predetermined position (position of the folding line L1 shown in FIG. 2A). Further, as shown in FIGS. 5 (a), 5 (c) and 5 (d), the circular reinforcing recess 41A3C presses a predetermined position on the upper surface of the transfer plate 41A so as to be recessed into a circular shape by a predetermined dimension, and It is provided by bulging the corresponding lower surface (back surface) side. The support wall 41A2D and the reinforcing recess 41A3C can be formed integrally with the transfer plate 41A by, for example, press-molding a flat transfer plate 41A having an insertion hole 41A1 in the center.

When the transfer plate 41A, to which the T-shaped lock rod 43 is fixed, is fixed to the inner peripheral surface of the end portion of the column 2, as shown in FIG. The upper surface of the transfer plate 41 A is fixed to the inner peripheral surface of the support column 2 by welding or the like at a position entering the inside by the dimension. The fixing position of the transfer plate 41A with respect to the column 2 is below the lock rod 431 of the lock rod 43 inserted into the insertion hole 34 of the fitting protrusion 32 when the column 2 is fixed to the top plate 1. It is preferable that the end surface be positioned so as to barely protrude on the spiral surface S.

As described above, even when the support wall 41A2D having a predetermined height is provided vertically downward on the outer peripheral edge in the major axis direction of the transfer plate 41A, the transfer plate 41A is arranged with respect to the inner peripheral surface of the end portion of the column 2. At the time of fixing, the support wall 41A2D is supported by contacting the inner peripheral surface of the support column 2 and is not inclined, so that the transfer plate 41A is fixed obliquely to the inner peripheral surface of the support column 2. Can be prevented. As a result, the T-shaped lock rod 43 fixed to the transfer plate 41A is not inclined, so that there is no trouble when the column 2 is attached to the top plate 1.

Further, providing the circular reinforcing recess 41A3C on the transfer plate 41A makes it possible to increase the rigidity as compared with the case where the linear reinforcing recess 41A3S is provided. As a result, when the column 2 is attached to the top plate 1, even if a force that pulls the transfer plate 41A upward is applied by rotating the column 2 in the tightening direction, the reinforcing recess With the presence of 41A3C and the support wall 41A2D, it is possible to satisfactorily prevent deformation such as the warping plate 41A warping upward.

Subsequently, the transfer plate 41A shown in FIG. 7 (a) is provided with a support wall 41A2U having a predetermined height on the outer peripheral edge in the major axis direction vertically upward, and is separated from the insertion hole 41A1 by a predetermined dimension in the radial direction. In this case, a circular reinforcing recess 41A3C is provided concentrically with the insertion hole 41A1 at a position where the outer peripheral edge in the minor axis direction is not exceeded.
In addition, the transfer plate 41A shown in FIG. 7 (b) is provided with a support wall 41A2D having a predetermined height perpendicular to the outer peripheral edge in the long axis direction, and the outer peripheral edge in the short axis direction and the insertion hole 41A1. A linear reinforcing recess 41A3S is provided along the major axis direction at a position between them.
The support walls 41A2U and 41A2D and the reinforcement recesses 41A3S and 41A3C of the transfer plate 41A shown in FIG. 7 are the same as the support walls 41A2U and 41A2D and the reinforcement recesses 41A3S and 41A3C of the transfer plate 41A shown in FIGS. Can be provided.

That is, the support ring 41C5 is formed, for example, by press-molding a flat plate-shaped transfer plate 41C having an insertion hole 41C1 drilled in the central portion together with the support wall 41C2U, the reinforcing recess 41C3S and the reinforcing protrusion 41C4U. And can be formed integrally.

In the transfer plate 41C shown in FIG. 19 configured as described above, the same effect as that of the transfer plate 41C shown in FIG. 16 can be obtained. By providing the support ring 41C5 having a predetermined height so as to surround 41C1, the rigidity of the central portion of the transfer plate 41C can be increased. It becomes possible to further increase the rigidity of the entire transfer plate 41C. As a result, even when the thickness of the transfer plate 41C is thin, when the support column 2 is attached to the top plate 1, the transfer plate 41C is pulled upward by rotating the support column 2 in the tightening direction. Even if a strong force is applied, it is possible to prevent deformation such as the warping plate 41C warping upward.

Further, when the vertical bar 432 constituting the lock bar 43 is fixed to the transfer plate 41C by welding or the like with the vertical bar 432 inserted through the insertion hole 41C1, the vertical bar 432 is vertically supported by the support ring 41C5, and swings and tilts. Therefore, the vertical bar 432 can be accurately fixed to the transfer plate 41C. As a result, there is no trouble in attaching the support column 2 to the top plate 1.
