As described above , the stand with legs according to the present invention includes a stand body and at least three legs that are opened and closed by a slider housed in the stand body from the lower end opening of the stand body. In addition, each leg can be bent and extended, one end of each leg can be pivotally connected to the lower end of the slider, and the other end of each leg can be pivoted to the side of the stand body According to such a stand with legs, each leg can be placed in an open or closed position by pushing or pulling out a slider housed in the stand body, and the stand with legs can be easily transported, installed and removed. Can do. Moreover, each leg part is made into the expansion | extension attitude | position by drawer | drawing-out of a slider, and there exists an outstanding effect that the stand with a leg in a horizontal direction can be piled up and stored efficiently.

  The best mode for carrying out the present invention will be described with reference to the drawings. 1 to 6 show an embodiment of the present invention. In the figure, reference numeral 1 denotes a legged stand for regulation.

  As shown in FIG. 1, the leg stand 1 includes a stand body 2 and three legs 3 that can be opened and closed.

  The stand main body 2 is an elongated rectangular tube member having a height of about 80 cm, and is formed in an equilateral triangular cross section in which the angle between the side surfaces 4 adjacent to each other is 60 degrees as shown in the plan view of FIG.

  The three legs 3 support the stand body 2 in a vertical posture on the ground G (or floor surface), and are housed in the stand body 2 from the lower end opening 5 of the stand body 2 as shown in FIG. The slider 6 made of a pipe member made can be opened and closed.

  A specific configuration of each leg 3 will be described. Each leg 3 includes two blades that can be bent and extended, that is, a support blade 7 and a connecting blade 8. The support blade 7 and the connecting blade 8 are connected to each other by a connecting pin 9 and can be bent and extended. The other end of each support blade 7 is pivotally connected by a connecting pin 10 to a front end portion 6 a of a slider 6 housed in the stand main body 2 from a lower end opening 5 of the stand main body 2. Further, the other end of each connecting blade 8 is connected by a connecting pin 11 at a position slightly below the corresponding side surface 4 of the stand body 2.

  As a result, in each leg portion 3, the three support blades 7 are simultaneously placed in a horizontal posture with respect to the ground G at the time of maximum bending due to the pushing operation of the slider 6, thereby supporting the stand body 2 in a vertical posture on the ground G. can do. At this time, the connecting blade 8 between the support blade 7 and the stand body 2 acts so as to maintain the horizontal posture of the support blade 7.

  In addition, each leg portion 3 is connected to the side surface 4 of the stand body 2 when the connecting blade 8 and the support blade 7 are at the maximum extension by the pulling operation of the slider 6 (at this time, half of the slider 6 remains in the stand body 2). At the same time, the cross section is triangular as a whole (see FIG. 2). As a result, as shown in FIG. 4, the side surfaces of the respective leg portions 3 substantially coincide with the side surfaces 4 of the stand body 2. Therefore, when each leg 3 is extended to the maximum, the outer shape of the stand body and the shape formed by each leg 3 are substantially the same, which is advantageous when the stands 1 are stacked and stored.

  At the upper end of the stand main body 2, a latching portion 13 including three rod members 12 that latch the regulation rope is provided. Each bar member 12 is attached and fixed to the inside of the upper end opening 14 of the stand main body 2 so as to face the longitudinal direction of the stand main body 2 by welding or the like, and does not become an obstacle when the stand 1 is stacked and stored.

  In the present embodiment, the material of the stand body 2 and each leg 3 is made of iron, but the material is not limited to this, and may be made of other metals (such as stainless steel or aluminum) or plastic. Moreover, although the stand main body 2 and each leg part 3 are colored yellow, coloring is not restricted to this.

  Next, the usage method of the leg stand 1 comprised as mentioned above is demonstrated below.

  First, the necessary number of leg stands 1 placed horizontally in the warehouse are transported to the site. As shown in FIG. 4, the legged stand 1 is stored in a state in which the leg portions 3 are folded, so that one person can carry several pieces at a time.

  When arriving at the site of the restricted area, the slider 6 is pushed from the lower end opening 5 of the stand body 2 to open the legs 3. As shown in FIG. 3 (A), when the worker holds the leg stand 1 vertically and lightly presses the leg stand 1 against the ground G, as shown in FIG. 2 can be pushed from the lower end opening 5 and the legs 3 in the extended posture can be bent at the same time.

  According to the pushing operation of the slider 6, each leg portion 3 is largely bent, and when the side surface of each supporting blade 7 near the slider 6 comes into contact with the edge of the lower end opening 5 of the stand body 2, the pushing operation of the slider 6 stops ( Each support blade 7 is in a horizontal posture with respect to the ground G, and the stand body 2 is in a vertical posture with each support blade 7 grounded on the ground G as shown in FIG. Can be supported.

  In this way, as shown in FIG. 5, the stand 1 with legs for dividing the inside and outside of the restriction area is installed at a constant interval near the boundary, and finally the restriction rope 13 is attached to the latching portion 13 of each stand body 2. Multiply 15 sequentially. Note that FIG. 5 shows an example in which the periphery of the manhole 16 is a restricted area, and a plurality of legged stands 1 are installed around the manhole 16 to form a barricade.

  As shown in FIGS. 3 (A) and 3 (B), the operator simply opens the legs 3 at a time by lightly pressing the stand 1 with the legs against the ground G, so that the stand body 2 can be quickly installed on the ground G. can do. There is no trouble of assembling the leg portions 3 or opening the legs one by one, and the installation work can be performed easily and quickly.

  After completion of the work in the restricted area, each installed stand 1 with legs can be quickly removed. That is, when the leg stand 1 is lifted, the slider 6 is automatically pulled out by the weight of the slider 6, and the leg portions 3 simultaneously start the leg closing operation. When an operator grips the bent portion of each leg 3 with his / her hand to extend the entire leg 3 straight (at the maximum extension), the connecting blade 8 and the support blade 7 are straight as shown in FIG. And the same direction and the same angle as the side surfaces 4 of the stand body 2, and the side surfaces of the leg portions 3 substantially coincide with the side surfaces 4 of the stand body 2.

  Since the stand 1 with legs can be folded into a long and compact shape on the site, several people can carry them together to the warehouse. When the stand 1 with legs is viewed in cross section, the stand main body 2 part and each leg part 3 part have substantially the same shape, and the cross-sectional shape is an equilateral triangle. As shown in FIG. The stand 1 with the legs 3 folded up can be efficiently stacked and stored in the left-right direction and the up-down direction without substantial gaps.

  According to the legged stand 1 of the present embodiment, as shown in FIG. 6, it can be efficiently stacked without a substantial gap, so that the storage space is not bulky and the storage space can be saved. For this reason, an optimal shape for storing a large number of legged stands can be realized.

  As shown in FIG. 2, the legged stand 1 of this embodiment has a triangular cross section, but may have a polygonal shape. For example, the cross section may be a quadrangular shape, and a total of four leg portions 3 corresponding to each side surface may be provided, or five leg portions 3 may be provided as a pentagonal shape.

  The stand with legs according to the present invention can be temporarily used outdoors or indoors, and can be used as a tool for partitioning restricted areas such as entry prohibition and safety, etc., and can also be widely used as a sign stand and floor stand for stores and events. is there.
