First, the first embodiment shown in FIG. 1 to FIG. 6 is a positioning device for a moving side structure according to the first to fifth aspects of the present invention, and includes a rotating cam 16 that contacts the tilting lever 6 in common. Further, an embodiment in which a rotation handle lever 21 is provided in the middle portion of the handle shaft 17 is shown.
That is, it is composed of a large-diameter pipe material 1 and a small-diameter bar material 2 fitted into the hollow portion of the pipe material 1 so as to be able to enter and exit (however, this bar material 2 can be a pipe material in general; the same applies hereinafter). A metal-made cylindrical positioning member 3 having a hollow structure in the same direction as the pipe material 1 is fixed to the large-diameter pipe material 1 in the moving mechanism by a fixture 4 having a clamp structure.
1 and FIG. 2 are large-diameter pipe members 1 constituting two parallel pillars standing upright on both sides of the short side among the pillars at the four corners constituting the pipe structure 10 as shown in FIG. And an example of a moving mechanism using a small-diameter bar 2 is shown. In other words, the large-diameter pipe material 1 corresponds to the fixed-side column, and the small-diameter bar 2 corresponds to the moving-side column. The small-diameter bar 2 which is the moving side support is used for the construction of the moving side structure 12 based on this, and the top plate portion 12D is supported on the upper frame of the moving side structure 12. . The upper frame shown in the figure has a short side formed by one pipe material 12A, and a long side is constructed in a double pipe structure by two pipe materials 12B and 12C.

  In the hollow portion of the positioning member 3, a band steel plate-like position adjusting plate 5 having an appropriate buckling resistance is penetrated so as to be movable in the vertical direction. The base end portion (upper end portion) of the position adjusting plate 5 can be tilted to the short-side pipe member 12A constituting the upper frame of the moving side structure 12 constructed on the basis of the small-diameter bar 2. It is connected to. More specifically, as shown in FIG. 2, the upper end of the position adjusting plate 5 is bent at a substantially right angle to form the tilting lever 6, and the fulcrum portion of the tilting lever 6 is connected to the pipe by the rotation clamp 7. It is connected to the material 12A. Therefore, when the tilting lever 6 is lifted upward, the position adjusting plate 5 rotates and tilts around the pipe material 12A. The position adjusting plate 5 is provided with a plurality of holes 8 which are positioned elements with a substantially constant interval in the longitudinal direction.

On the other hand, the positioning member 3 is provided with an elastic member that presses against one inner surface of the positioning member 3, that is, the right inner surface in FIG. 4 while allowing the position adjusting plate 5 to move in the vertical direction. In this case, it is installed as a leaf spring 9. However, a plastic spring or the like can be selected and used as the elastic member. On the other hand, in the positioning member 3, a protrusion 15 is provided on the inner surface side as a positioning element that is fitted and positioned in the hole 8 as the positioned element of the position adjusting plate 5 pushed by the plate spring 9.
Therefore, for example, when the tilting lever 6 is rotated upward (counterclockwise) as shown in FIG. 5B, the position adjusting plate 5 overcomes the pushing action of the leaf spring 9 which is an elastic member. When it tilts at a certain angle as represented by the two-dot chain line and tilts beyond the height of the projection 15, the hole 8 as the positioned element is detached from the projection 15 of the positioning member 3, and the small-diameter bar 2 and eventually The moving side structure 12 constructed on the basis of the small-diameter bar 2 can be freely moved, and can be moved in the vertical direction in the figure, and the position can be adjusted.
Of course, when the action (force) of rotating the tilting lever 6 upward is eliminated, the position adjusting plate 5 is restored to the position in close contact with the inner surface of the positioning member 3 by the pushing action of the leaf spring 9, and just the position. Are fitted into the protrusions 15 into the aligned holes 8 to be positioned (see FIG. 5A).
In other words, the small-diameter bar 2 that is the moving-side column and the small-diameter bar 2 on the basis of the small-diameter bar 2 by the one-touch operation only by rotating the tilting lever 6 (or moving upward in the illustrated example). Thus, it is possible to freely adjust the position of the moving-side structure 12 constructed as described above, and to position the adjusted position easily.

In the case of the embodiment shown in FIG. 1, each of the moving mechanisms of the large-diameter pipe member 1 and the small-diameter bar member 2 arranged in parallel on the left and right sides, and the embodiment shown in FIG. 6. In this case, each of the moving mechanisms by the four large-diameter pipe members 1 and the small-diameter bar members 2 arranged as pillars at the four corners is provided with a tilting lever 6, a position adjusting plate 5, a plate spring 9, and a protrusion 15 Although the positioning apparatus which consists of the positioning member 3 provided with is installed, it is not this limitation.
The weight of the moving side structure 12 constructed on the basis of the small-diameter bar 2 and the weight of the load loaded on the moving side structure 12 are small, and the moving side structure 12 can be obtained with a single positioning device. In the case of a design load condition that can position and support the loaded load, only a single positioning device can be installed in any one of the moving mechanisms (according to claim 1). invention).

On the other hand, as in the inventions described in claims 3 to 5, more specifically, as shown in FIGS. 1 and 6, two or four arranged substantially in parallel with an interval therebetween. The positioning device having the above-described configuration is individually provided for each of the moving mechanisms including the large-diameter pipe material 1 that constitutes the support column and the small-diameter bar material 2 that is fitted into the hollow portion of the pipe material 1 so as to be able to enter and exit. It is also preferable to install and implement.
However, in such an embodiment, the position adjusting plate 5 of each positioning device is tilted by an operation that is equal to the unity or as a common operation, and the hole 8 that is a positioned element is used as the positioning element of the positioning member 3. By simultaneously detaching from the protrusions 15, the moving side structure 12 can be moved, and the position of the moving side structure 12 can be adjusted.

Therefore, as in the embodiment shown in FIGS. 1, 2, and 6, the upper frame of the moving-side structure 12 constructed on the basis of the small-diameter bar 2 is formed in a rectangular shape in plan view. Is composed of two large-diameter pipe members 1 arranged adjacent to each other in the short side direction, and a small-diameter bar member 2 fitted into the hollow portion of the pipe member 1 so as to be able to enter and exit.

Therefore, when the handle shaft 17 is rotated in the forward rotation direction by a necessary rotation angle, the two rotating levers 6 and 6 that come in contact with the rotating cams 16 and 16 rotate upward by the same angle. As a result, the position adjusting plates 5 and 5 subordinate to each other are tilted equally in a fixed direction, and the holes 8 as the positioning elements are simultaneously detached from the projections 15 as the positioning elements of the positioning member 3, thereby moving the moving side structure 12. Is movable (see FIG. 5B).
Therefore, the height position of the moving structure 12 can be freely adjusted by the above operation. Then, after the position is adjusted, when the handle shaft 17 is restored to the original position (or the force for rotating the tilting levers 6, 6 is eliminated), the acting force of the leaf spring 9 of the positioning member 3 Then, the protrusion 15 is fitted into the hole 8 of the position adjusting plate 5 and is again positioned (see FIG. 5A).

In the case of the first embodiment shown in FIGS. 1, 2, and 6, the handle shaft 17 is rotated by the rotation handle lever 21 that is attached and fixed to an intermediate portion of the handle shaft 17.
On the other hand, in the case of the second embodiment shown in FIGS. 7 and 8, no special rotating handle is installed on the handle shaft 17. Instead, one end portion 17a of the handle shaft 17 is configured to protrude slightly longer outward than the positions of the long side double pipe members 12B and 12C constituting the upper frame of the movable side structure 12. ing.
That is, in the case of the second embodiment, the operator directly grips and rotates the end portion 17a of the handle shaft 17 protruding slightly longer outward than the positions of the pipe members 12B and 12C, or is necessary. Accordingly, the height position of the movable structure 12 is adjusted by attaching and rotating a handle (not shown) to the end portion 17a.

Each of the four pillars arranged as support columns is configured as a moving mechanism by the large-diameter pipe member 1 and a small-diameter bar member 2 fitted into the hollow portion of the pipe member 1 so as to be able to enter and exit. A fixed-side structure is constructed using the large-diameter pipe member 1 as a fixed-side column, and a wheel 20 is attached to the lower end of each column (large-diameter pipe member 1), for example, as a mobile wagon table. On the other hand, the small-diameter bar 2 fitted into the hollow part of the large-diameter pipe material 1 so as to be able to enter and exit is used as a movable-side column, and a movable-side structure 12 is constructed as the foundation of the small-diameter bar 2 and its upper frame As an example, the top plate portion 12D is supported.
Then, on the premise of the structure of the fixed side structure based on the large diameter pipe material 1 and the moving side structure 12 based on the small diameter rod 2, each large diameter pipe material 1 and the same pipe material The positioning device having the above-described configuration is installed in each of the moving mechanisms configured with the small-diameter bar 2 fitted into the hollow portion of 1 so as to be able to enter and exit.
