(Constitution)
The stand of this invention is demonstrated with reference to FIGS. FIG. 1 is a schematic view of a stand according to the present invention. 2 to 4 are schematic views showing cut end surfaces of the stand of the present invention. 2 (A), 3 (A) and 4 show a cut surface obtained by cutting the stand of the present invention along a surface along the longitudinal direction of the main shaft. FIG. 2B and FIG. 3B show a cut surface obtained by cutting the main shaft and the second leg portion by a plane orthogonal to the longitudinal direction of the main shaft. In each figure, some constituent elements of the stand of the present invention may be omitted.

  The stand of the present invention includes a main shaft 10, a first leg portion 20, a second leg portion 30, and a support portion 40.

  The main shaft 10 is substantially cylindrical. Near both ends of the main shaft 10, a set of a first leg 20, a second leg 30, and a support 40 is provided. In each figure, there are places where the diameter of the main shaft 10 is different. About this structure, you may form by shaving the side surface of one cylinder, and you may form by 2 or more components, such as providing another cylinder outside the one cylinder.

  The first leg portion 20 includes a first plate-like portion 22 and a first cylindrical portion 24 that are fixed to each other. The first plate-like portion 22 is provided so as to protrude in the radial direction of the main shaft 10. The main shaft 10 is provided so as to penetrate the first cylindrical portion 24. When the cut surface of the surface perpendicular to the longitudinal direction of the main shaft 10 is seen in the portion penetrating the first cylindrical portion 24, the main shaft 10 and the first cylindrical portion 24 are substantially concentric. The first leg 20 is fixed to the main shaft 10.

  The second leg portion 30 includes a second plate-like portion 32 and a second cylindrical portion 34 that are fixed to each other. The second plate-like portion 32 is provided so as to protrude in the radial direction of the main shaft 10 similarly to the first plate-like portion 22. The main shaft 10 is provided so as to penetrate the second cylindrical portion 34. When the cut surface of the surface perpendicular to the longitudinal direction of the main shaft 10 is seen in the portion penetrating the second cylindrical portion 34, the main shaft 10 and the second cylindrical portion 34 are substantially concentric. The second leg portion 30 is provided so as to be rotatable about the main shaft 10 and slidable along the main shaft 10.

  An opening 38 reaching the hollow portion 36 through which the main shaft 10 passes is provided on the side surface of the second cylindrical portion 34. A pin 52 is attached to the opening 38. The pin 52 can take a state where the tip reaches the hollow portion 36 and a state where the tip is located in the opening 38 of the side wall 35 of the second cylindrical portion 34.

  A slit 12 is provided at a position where the second leg 30 of the main shaft 10 is attached. The pin 52 attached to the second leg portion 30 is positioned in the slit 12 in a state where the tip reaches the hollow portion 36. In the state where the pin 52 is positioned in the slit 12, the rotation of the second leg 30 around the main shaft 10 is suppressed. That is, the pin 52 attached to the second leg 30 and the slit 12 provided on the main shaft 10 constitute a leg rotation suppression means. When the pin 52 is pulled out, the second leg 30 can rotate about the main shaft 10 (FIG. 2), and when the pin 52 is pushed in, rotation of the second leg 30 is suppressed (FIG. 3). ).

  The support portion 40 includes a support plate-like portion 42, a first rotation plate-like portion 44, and a second rotation plate-like portion 46. The supporting plate-like portion 42 is provided so as to protrude in the radial direction of the main shaft 10. Each of the first rotation plate-like portion 44 and the second rotation plate-like portion 46 has a support plate-like shape on one end side of two long sides which are sides along the longitudinal direction of the support plate-like portion 42. It is provided so as to be orthogonal to the width direction of the portion 42. Each of the first rotation plate-like portion 44 and the second rotation plate-like portion 46 is formed with an opening through which the columnar main shaft 10 passes. With the configuration in which the main shaft 10 is passed through the openings of the first rotation plate-like portion 44 and the second rotation plate-like portion 46, the support portion 40 can rotate with respect to the main shaft 10.

  The width of the support plate-like portion 42 is substantially equal to the height of the first cylindrical portion 24 of the first leg portion 20 (the length in the direction along the main axis), and the first rotation plate-like portion 44 and the second rotation. The plate-like portion 46 is disposed at a position sandwiching the first cylindrical portion 24. With this configuration, the position of the support portion 40 in the direction along the main shaft 10 is fixed.

  The slit 12 provided at a position where the second leg portion 30 of the main shaft 10 is attached is provided, for example, in an elliptical shape or a rectangular shape that is long in the direction along the main shaft 10. For this reason, in the state where the pin 52 is pushed in, the rotation of the second leg portion 30 is suppressed. Even in this state, the second leg portion 30 is in the direction along the main shaft 10 within the range of the length of the slit 12. (FIG. 3).

  The surface 34a of the second cylindrical portion 34 that is in contact with the first rotating plate-like portion 44 and the surface 44a of the first rotating plate-like portion 44 that is in contact with the second cylindrical portion 34 are provided so as to be fitted to each other. A crown gear is provided. These two crown gears constitute the support portion rotation restraining means.

  These crown gears may be formed integrally with the second cylindrical portion 34 and the first rotating plate-like portion 44, or formed separately from the second cylindrical portion 34 and the first rotating plate-like portion 44, and screwed. You may join by a stop etc.

  In addition, what is necessary is just to provide many teeth of a crown gear, when increasing the angle which can be set of the support part 40 with respect to the 2nd leg part 30, ie, changing an angle more finely.

  As shown in FIG. 4, when the second leg portion 30 is in the support portion fixed state closest to the first leg portion 20 and the support portion 40, the second cylindrical portion 34 of the second leg portion 30 and the first of the support portion 40. The rotating plate-like portion 44 contacts. In the support portion fixed state, the two crown gears are fitted, and the rotation of the support portion 40 is suppressed.

  On the other hand, as shown in FIG. 3A, the second cylindrical portion 34 of the second leg portion 30 is in the support portion open state where the second leg portion 30 is located away from the first leg portion 20 and the support portion 40. And the first rotating plate-like portion 44 of the support portion 40 are separated from each other. In the support portion open state, the support portion 40 can be rotated about the main shaft 10.

  As shown in FIG. 4, a sealing pin 54 is attached to the end of the main shaft 10 as a leg sliding restraining means. When the sealing pin 54 is fixed to the main shaft, the second cylindrical portion 34 of the second leg portion 30 is pressed against the first rotating plate-like portion 44 of the support portion 40 to be in a support portion fixed state. At this time, sliding of the second leg 30 in the direction along the main axis 10 is suppressed. On the other hand, when the sealing pin 54 is removed from the main shaft 10, the support portion is opened.

  The sealing pin 54 is preferably provided with a spring inside so that the second cylindrical portion 34 is pressed against the first rotating plate-like portion 44. If the second cylindrical portion 34 is pressed against the first rotation plate-like portion 44 by this spring, even when a heavy object such as a mirror is placed on the support portion 40, the support portion 40 does not rotate and is stable. Can be used.

  Moreover, since the stand is folded compactly by fixing the first plate-like portion 22, the second plate-like portion 32, and the supporting plate-like portion 42 so as to be in the same direction, accommodation and transportation are facilitated.

(how to use)
With reference to FIGS. 2-4, an example of the usage method of the stand of this invention is demonstrated.

  First, as shown in FIGS. 2A and 2B, the second leg 30 is rotated with the sealing pin 54 removed from the main shaft 10 and the pin 52 of the second leg 30 pulled out. Let Due to the rotation of the second leg portion 30, the surfaces on the installation surface side of the main surfaces of the first plate-like portion 22 of the first leg portion 20 and the second plate-like portion 32 of the second leg portion 30 are the same. Make it flat.

  In this state, as shown in FIGS. 3A and 3B, the pin 52 of the second leg 30 is pushed in to prevent the rotation of the second leg 30.

  Next, the support part 40 is rotated to a desired angle. In this state, as shown in FIG. 4, the second leg portion 30 is moved to the support portion 40 side, and the crown gears are fitted to each other. Thereafter, the sealing pin 54 is fixed to the main shaft 10 to be in a support portion fixed state.

  Since the stand is now ready for use, a mirror or the like is placed on the support portion 40 for use. In order to mount and fix a mirror or the like, the supporting plate-like portion 42 may be provided with any suitable supporting object fixing means such as a pin or a slit.

  When the angle of the support part 40 is changed during use, the sealing pin 54 is removed, the support part is opened, the support part 40 is moved in the circumferential direction with the main shaft 10 as the rotation axis, and the desired angle is obtained. After that, the sealing pin 54 may be fixed to the main shaft so that the support portion is fixed.

  When the stand is accommodated or transported, the sealing pin 54 is removed with the support object such as a mirror removed, and the stand is folded in the same procedure as in the above use.

  Two slits 12 provided on the main shaft 10 are preferably provided on the opposite side along the center line of the main shaft 10. One slit is used to suppress the rotation of the second leg when the angle of the first plate-like portion 22 and the second plate-like portion 32 is approximately 180 degrees when the stand is used. However, it is used to suppress the rotation of the second leg portion with the angle of the first plate-like portion 22 and the second plate-like portion 32 being set to approximately 0 degrees when the stand is accommodated or transported.

(Example)
In addition, when the stand is used, the surfaces on the installation surface side of the main surfaces of the first plate portion and the second plate portion are the same plane, but the installation surface is not necessarily flat. Therefore, it is preferable to provide auxiliary legs for height adjustment on the surfaces on the installation surface side of the main surfaces of the first plate-like portion and the second plate-like portion.

  Moreover, in the support part open state, although the sealing pin is removed from the main shaft, the sealing pin and the main shaft do not necessarily need to be physically separated. For example, when the sealing pin is fixed to the main shaft by so-called screwing, the screw of the sealing pin may be loosened to such an extent that the second leg can slide along the shaft.

  Here, the example in which the stand mounts the mirror has been mainly described, but what is mounted on the stand is not limited to this. A plate-shaped object such as a liquid crystal panel can be placed.
