Description of the Related Art Conventionally, a detachable handrail that is detachably attached to an installation surface such as a gantry or a stage is known (for example, see Patent Document 1). This type of handrail generally includes a handrail main body having a plurality of support columns and a plurality of holding bodies for attaching the plurality of support columns to an installation surface such as a gantry or a stage.

  Each holding body has a cylindrical shape, is fixed to the installation surface, and is configured to be fitted and held at one end in the longitudinal direction of the support column corresponding to the fixing body. Therefore, the supporting column is supported by the holding body so that the handrail main body stands on the installation surface, and the handrail can be attached to the installation surface.

  However, in the handrail, when supporting the support column with the support body, the outer shape of one end in the longitudinal direction of the support column corresponding to the inner shape of each support body is set so that the handrail main body does not tilt greatly. Are made to have the same shape (round shape), and both are fitted together, making it difficult to perform the fitting operation.

  When the handrail is a temporary handrail, it is desired that the handrail is quickly attached to the installation surface, but one end in the longitudinal direction of the plurality of support portions is fitted into the plurality of holding bodies substantially simultaneously. Since it had to be done, it took a relatively long time for the fitting operation, and it was difficult to carry out the mounting operation of the handrail as desired.

  In addition, since the difference between the inner diameter of the holding body and the outer diameter of one end in the longitudinal direction of the support column is only slight, the processing accuracy is slightly worse, or the longitudinal end of the support column is slightly However, if it is deformed, one end of the longitudinal direction cannot be fitted into the holding body by a necessary amount, that is, the handrail cannot be securely attached and detached, and the handrail main body is erected on the installation surface. May not be held stably.

  The positioning stopper 25 is externally fitted and fixed to the support columns 6A and 6B, and is configured to come into contact with the holding bodies 4A and 4B from above. Therefore, the positioning stopper 25 can prevent the support portions 6A and 6B from being fitted into the holding bodies 4A and 4B by a predetermined amount or more due to contact with the holding bodies 4A and 4B.

  With such a configuration, the holding bodies 4A and 4B are fixed to the installation surface 2, and then the lower end portions 11A and 11B of the support columns 6A and 6B are fitted into the holding bodies 4A and 4 and held. By doing so, the handrail main body 3 can be erected on the installation surface 2 at a predetermined vertical position. That is, the handrail 1 can be attached to the installation surface 2.

  Further, in a state where the handrail 1 is attached to the installation surface 2, the handrail body 3 is moved so that the lower end portions 11A and 11B of the support columns 6A and 6B are extracted from the holding bodies 4A and 4B. Then, the handrail 1 can be removed from the installation surface 2 by releasing the fixing of the holding bodies 4A and 4B with respect to the installation surface 2.

  Next, the structure for attaching the handrail 1 to the installation surface 2 will be described in detail.

  In FIG. 2, the front view of the lower left part of the handrail 1 is shown. In FIG. 3, the side view of the lower left part of the handrail 1 is shown. In FIG. 4, the bottom view of the lower left part of the handrail 1 is shown. Since the handrail 1 has substantially the same structure on both the left and right sides, the structure on the left side of the handrail 1 will be described here.

  As shown in FIG. 1, on the left side of the handrail 1, one strut portion (left strut portion) 6 </ b> A among the plurality of strut portions 6 is provided. As shown in FIGS. 3, 4, and 5, in the lower left portion of the handrail 1, a lower end portion 11 </ b> AB of the left column 6 </ b> A and one holding body (left holding body) among the plurality of holding bodies 4. 4A is arranged.

  And when the lower end part 11A of the left column 6A is fitted into the left holding body 4A, the left holding body 4A has a proximity part 31 that is close to the lower end part 11A so as to sandwich the lower end part 11A. The lower end portion 11A has an inner shape that is different from the outer shape of the lower end portion 11A so that a separation portion 32 that is separated from the lower end portion 11A by a larger interval than the adjacent portion 31 is formed.

  In the present embodiment, the outer shape of the lower end portion 11A of the left column portion 6A is formed in a round shape when viewed from the bottom of the handrail 1 (sectional view orthogonal to the longitudinal direction of the left column portion 6A). The lower end portion 11A has a substantially uniform outer diameter D1 with respect to the longitudinal direction of the left strut portion 6A, and has an outer diameter D1 that is substantially the same as the longitudinal intermediate portion 13A.

  On the other hand, the inner shape of the left holding body 4 </ b> A is formed in a rectangular shape when the handrail 1 is viewed from the bottom. The left holding body 4A has a rectangular cylindrical shape having a short portion 35 and a long portion 36 so that the short portion 35 extends in the front-rear direction and the long portion 36 extends in the left-right direction. It is fixed to the installation surface 2.

  The short portion 35 has an inner width W1 that is substantially the same as or slightly larger than the outer diameter D1 of the lower end portion 11A of the left column portion 6A. The short portion 35 forms the separation portion 32 when the lower end portion 11A is fitted into the left holding body 4A, and is provided so as to face the lower end portion 11A with a predetermined interval. .

  The long portion 36 has an inner width W2 that is larger than the inner width W1 of the short portion 35. The longitudinal portion 36 forms the proximity portion 31 when the lower end portion 11A is fitted into the left holding body 4A, and this has a slight interval (<predetermined interval) from the lower end portion 11A (or It is provided so that it may oppose (without a space | interval).

  Therefore, when the lower end portion 11A of the left column 6A is fitted into the left holding body 4A, as shown in FIG. 4, the left holding body 4A has an inner surface between the inner surface of the left holding body 4A and the outer surface of the lower end portion 11A. Different intervals are secured in the circumferential direction of the lower end 11 of the left column 6A.

  Specifically, a gap between the two is substantially zero in the vicinity of the proximity portion 31, and a space that increases from here toward the vicinity of the separation portion 32 is secured. That is, the left holding body 4A does not surround the lower end portion 11A while keeping a substantially uniform minute interval over the entire circumference (tightly fit).

  With the configuration as described above, in the handrail 1, the inner width W2 has a margin in the direction (longitudinal direction) in which the holding bodies 4A and 4B are in a certain direction (longitudinal direction) with respect to the lower end portions 11A and 11B of the support columns 6A and 6B. It will be equipped with. Therefore, the lower end portions 11A and 11B can be easily aligned with the holding bodies 4A and 4B, and can be easily fitted.

  Therefore, it becomes easy to fit the lower end portions 11A and 11B of the two support columns 6A and 6B into the two holding bodies 4A and 4A in a state of being fixed to the installation surface 2 almost simultaneously. Therefore, the handrail main body 3 can be easily erected on the installation surface 2, and the handrail 1 can be quickly attached and detached (attached).

  Moreover, the tolerance | permissible_range of the process precision of lower end part 11A * 11B etc. of each said support | pillar part 6A * 6B can be made wide. Moreover, even when the lower end portions 11A and 11B are slightly deformed while the handrail 1 is being used while repeatedly attaching and detaching, there is a high possibility that fitting into the corresponding holding body 4 can be permitted. .

  Therefore, the lower end portions 11A and 11B of the support column portions 6A and 6B can be securely fitted into the holding bodies 4A and 4A by a predetermined amount, and the handrail main body can be erected on the installation surface 2. That is, the handrail 1 can be reliably attached and detached. As a result, the handrail body raised on the installation surface 2 can be stably held.

  The predetermined amount can be appropriately set in order to prevent the handrail main body 3 from being blurred in the front-rear direction. In the present embodiment, the lower end portions 11A and 11B of the support columns 6A and 6B are respectively This is an amount necessary to bring the positioning stopper 25 into contact with the support portions 6A and 6B when fitted into the holding bodies 4A and 4A.

  Further, the holding bodies 4A and 4B sandwich the lower end portions 11A and 11B of the fitted support columns 6A and 6B with the proximity portion 31, so that the holding bodies 4A and 4B are sandwiched between the handrail main body 3 standing on the installation surface 2. Even when an external force is applied in the direction (short direction / front / rear direction), the handrail main body 3 can be prevented from being largely inclined with respect to the installation surface 2.

  Therefore, for example, in a frame or stage, a person on the installation surface 2 leans against the handrail body 3 toward the outside (front or rear side) of the frame or stage, or the handrail body 3 When the button is pressed, the standing state of the handrail body 3 can be stably maintained, and the function of the handrail 1 can be prevented from being hindered.

  In addition, although each said holding body 4 is each said holding body 4A * 4B which exhibits a cylindrical shape by itself, what is necessary is just to function similarly to this, for example, as shown in FIG. It is good also as the U-shaped holding body 44 which exhibits a cylinder shape, utilizing the said installation surface 2 in order to form the site | part 41 and the separation | spacing site | part 42. FIG.

  In the present embodiment, as shown in FIG. 1, the handrail 1 includes a guide body 50. The guide body 50 is for guiding the lower end portions 11A and 11B of the support columns 6A and 6B to the corresponding holding bodies 4A and 4B. The guide body 50 has a tapered shape and is attached to the lower end portions 11A and 11B.

  Specifically, the guide body 50 includes two guide bodies 50A and 50B. The two guide bodies 50A and 50B are connected to the lower end portions 11A and 11B of the two support column portions 6A and 6B on the base end (upper end) 51 side, respectively, and taper from here toward the distal end (lower end) 52 side. It is formed so that.

  As shown in FIGS. 2, 3, and 4, one guide body (left guide body) 50 </ b> A of the two guide bodies 50 </ b> A and 50 </ b> B is a lower end of the left column portion 6 </ b> A in the bottom view of the handrail 1. It is provided so as not to protrude radially outward from the outer peripheral surface of the portion 11A, and is configured to pass through the left holding body 4A with a margin.

  Here, the left guide body 50A includes two plate members 56 and 57 each having a trapezoidal shape. The two plate members 56 and 57 are combined in a T shape so as to have a tapered shape, and both are fixed to the lower end portion 11A of the left column portion 6A by appropriate fixing means on the upper end side which is relatively wide. .

  According to this configuration, when the handrail main body 3 is erected on the installation surface 2, it is only necessary to first insert the left guide body 50A into the left holding body 4A. Thus, the lower end portion 11A can be easily fitted into the left holding body 4A.

  Here, the guide body 50 is a guide body 50A (50B) in which the two plate members 56 and 57 described above are combined in a T-shape, but may be any one having a tapered shape. For example, FIG. As shown to (a) and (b), it is good also as the guide body 63 which combined the two board | plate materials 61 * 62 in the cross shape.

  The guide body 50 may be a tapered guide body 66 in which two plate members 64 and 65 are combined in a T shape and sharpened as shown in FIGS. 7A and 7B. As shown in FIGS. 8A and 8B, the two guide members 67 and 68 may be combined into a cross shape to form a tapered guide body 69 that is sharper.
