  As described above, according to the safety fence carrying jig according to the present invention, the safety fence can be safely and easily carried.

  Hereinafter, embodiments of a safety fence carrying jig according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing a schematic configuration of one embodiment of a safety fence carrying jig. FIG. 2 is a perspective view of the safety fence carrying jig with a plurality of safety fences attached thereto. The safety fence carrying jig 1 includes a safety fence support plate 2, a waist pad 3, and a holding portion 4 including a safety fence stopper plate 5 and a grip handle 6. Furthermore, an attachment jig 13 indicated by a broken line in FIG. 1 is provided on the back surface of the waist pad 3 of the safety fence carrying jig 1. This safety fence carrying jig 1 is inserted into the openings 11 of a plurality of sets of safety fences 10 in a folded state. In FIG. 1, as an example, a state in which two pairs of safety fences 10 each including four fences 9 are bundled is shown.

  The safety fence support plate 2 is a plate material that is inserted in a substantially horizontal state into the openings 11 of the bundled safety fences 10. And this safety fence support plate 2 plays the role which supports the safety fence 10 bundled by the flat plate surface from the downward direction. Therefore, the width (L) of the safety fence support plate 2 is a size that can accommodate the thickness of the bundled safety fence 10. For example, in order to bundle and transport two sets of safety fences 10 each consisting of four fences 9, the width (L) of the safety fence support plate 2 must have a dimension exceeding about 200 mm. Further, in order to bundle and transport two sets of safety fences 10 each having six fences 9 as a set, the width (L) of the safety fence support plate 2 must be a dimension exceeding about 300 mm.

  The waist pad 3 is a plate material attached to one end of the safety fence support plate 2 so as to be substantially orthogonal to the safety fence support plate 2. On the upper part of the waist pad 3, a waist pad return part 8 for protecting the fence 9 supported by the safety fence 10 may be provided. In the present embodiment, the waist plate 3 has a flat plate shape, but may be a curved surface that fits the waist because it is applied to the waist portion of the carrier. In addition, a cushion or the like may be attached so as not to feel pain to the waist.

  The holding unit 4 is attached to a plate-like safety fence stopper plate 5 that is attached substantially orthogonally to the safety fence support plate 2 and a surface opposite to the surface on which the safety fence support plate 2 is attached to the safety fence stopper plate 5. It consists of a handle 6 that is carried and gripped by hand. The grip handle 6 is a member having a cross-sectional shape of a bar or a cylinder, but may be another cross-sectional shape such as an ellipse as long as it is easily gripped because it is gripped by a human hand. The safety fence stop plate 5 is a plate for protecting the fence 9 of the safety fence 10 and is a member that is paired with the waist pad 3. In this embodiment, the safety fence stopper plate 5 and the grip handle 6 are connected by two grip handle attachment plates 7. The number and shape of the handle handle attachment plates 7 are the same as those of the safety fence stopper plates 5 and 6. The configuration is not limited to this as long as the grip 6 can be safely connected.

  In FIG. 3, the AA cross section of the safety fence carrying jig 1 of FIG. 2 is shown. Each fence 9 of the safety fence 10 is juxtaposed on the safety fence support plate 2 and protected by the waist pad 3 and the safety fence stopper plate 5 so as not to drop off. Further, as will be described later, since the compressive stress is transmitted to the safety fence support plate 2 and the grip handle mounting plate 7, each axis is prevented from generating a bending moment in the member and causing a buckling in the plate material. It is preferable that the cores are substantially coincident.

  Further, the waist plate 3 may be provided with an attachment jig 13 for attaching the safety fence carrying jig 1 to a belt worn by the carrier on the pants. In the present embodiment, as shown in FIG. 3, the attachment jig 13 has a hook shape, and hooks the hook between the belt and the trousers from above to fix the safety fence carrying jig 1 to the carrier. The mounting jig 13 is not limited to this hook-shaped one, and may be a ring-like one that allows the belt to pass through the ring like a belt stopper.

  In FIG. 4, the state at the time of using the safety fence conveyance jig 1 and its function are shown. FIG. 4A shows a state where the carrier 12 holds the safety fence carrying jig 1. The transporter 12 holds and transports a plurality of sets of safety fences 10 bundled by pressing the grip 6 of the holding unit 4 in the direction of the waist pad 3. In this case, the carrier 12 may support the safety fence carrying jig 1 as it is on the hip bone. Further, the safety fence carrying jig 1 may be supported by inserting the attachment jig 13 attached to the safety fence carrying jig 1 into the belt 14.

  The stress transmission function in the safety fence carrying jig 1 will be described with reference to FIG. The carrier 12, the carrier's arm 15, and the safety fence carrying jig 1 shown in FIG. 4A are each represented by a single line in FIG. 4B, and constitute a closed triangle. When the carrier 12 holds the safety fence carrying jig 1, the total weight (W) of the safety fence 10 to be held is two of the waist of the carrier 12 and the grip 6 of the holding unit 4. Each load (W / 2) is distributed to the fulcrum. The load (W / 2) transmitted to the waist of the carrier 12 is transmitted to the ground as it is through the feet of the carrier 12. On the other hand, the load (W / 2) transmitted to the handle 6 of the holding part 4 is applied to the handle handle mounting plate 7 and the safety fence support plate 2 of the safety fence carrying jig 1 as shown in FIG. It is decomposed into a compressive force (c) transmitted and a tensile force (T) transmitted to the arm 15 of the carrier. That is, this compressive force (c) is a force by which the carrier 12 presses the safety fence carrying jig 1 toward the waist. Further, the tensile force (T) is a force that the carrier 12 pulls the safety fence carrying jig 1 obliquely upward.

  Thus, according to the safety fence carrying jig 1 according to the present invention, the carrier 12 supports the load (W / 2) half of the entire weight (W) of the safety fence 10 to be held directly by the waist, The remaining half load (W / 2) may be obtained by pushing the safety fence carrying jig 1 toward the waist and pulling it toward the arm 15 of the carrier. That is, the overall weight (W) of the safety fence 10 is supported by the closed triangle formed by the carrier's arm 15, the carrier 12, and the safety fence carrying jig 1, and the carrier's arm 15, the carrier 12, and This is a mechanism in which no bending moment is generated in any of the safety fence carrying jigs 1. Therefore, the bundle of safety fences 10 can be held and transported without difficulty with a more natural posture.

  In this regard, in the invention described in the cited document 1, the worker turns his hand to the safety fence portable tool to grasp the grip handle 6 and bends his hand to hold and carry the safety fence portable tool. Therefore, the closed triangle that supports the load as described above is not constructed. Therefore, a bending moment is generated in the arm and body of the worker, and the worker holds the bundle of safety fences 10 with an unreasonable posture.

  In FIG. 5, the schematic structure of other embodiment of a safety fence conveyance jig is shown with a perspective view. FIG. 6A shows a side view of the safety fence carrying jig, and FIG. 6B shows a BB cross section of the safety fence carrying jig shown in FIG. As shown in FIG. 5A, the safety fence carrying jig 20 includes a safety fence support plate 21, a sheath portion 23, a waist support plate 3, a holding portion 4 including a safety fence stopper plate 5 and a handle 6. It is comprised from the insertion piece 24 and the extension board 22 shown in FIG.5 (b). That is, the safety fence carrying jig 20 can freely adjust the range (Q) for supporting the safety fence 10 by newly using the extension plate 22 with respect to the safety fence carrying jig 1. This is an embodiment. In addition, the description is abbreviate | omitted about the thing similar to previous embodiment among the components of this embodiment.

  The extension plate 22 is a plate material provided adjacent to the safety fence support plate 21 having a width (M) and having a width (N). The width (M) of the safety fence support plate 21 is, for example, a minimum width assuming a case where two sets of the safety fences 10 each including four fences 9 are bundled and transported. And the width | variety (N) of the extension board 22 is the safety fence support board 21 from the maximum width (Q) supposing the case where 2 sets of the safety fence 10 which made six sets of fences 9 are bundled and conveyed, for example. This is a value obtained by subtracting the width (M). That is, by using the extension plate 22, it is possible to cover the minimum width to the maximum width of the combination of the four and six fences 9. Moreover, the safety fence carrying jig 20 can be adapted to all combinations by preparing a plurality of extension plates 22 in advance and having different widths.

  A wedge-shaped convex portion 26 is provided at substantially the center of the extension plate 22 installed on the safety fence support plate 21 side. In addition, a wedge-shaped recess 25 is provided at a substantially central portion of the safety fence support plate 21 on the extension plate 22 side. Then, the wedge-shaped concave portion 25 and the wedge-shaped convex portion 26 are fitted. This is to prevent the extension plate 22 from slipping laterally when the extension plate 22 is installed adjacent to the safety fence support plate 21.

  As means for detachably adjusting the range (Q) for supporting the safety fence 10, in this embodiment, the insertion piece 24 and the sheath portion 23 into which the insertion piece 24 can be inserted are used. The insertion pieces 24 are plate members that are attached to at least two places on the safety fence support plate 21 side of the holding unit 4. The sheath 23 is a box-like member that is attached to the back side of the surface that supports the safety fence 10 in the safety fence support plate 21 and surrounds and holds the insertion piece 24 to be inserted. The length of the insertion piece 24 is defined so that the safety fence carrying jig 20 has a predetermined width (M) when the insertion piece 24 is completely inserted into the sheath portion 23.

  The carrier 12 adjusts the range in which the safety fence 10 is supported by the extension plate 22 according to the combination of the safety fence 10, and inserts the insertion piece 24 into the sheath portion 23. Then, a plurality of sets of safety fences 10 that are bundled by pressing the holding plate 4 in the direction of the waist plate 3 are held and transported.

  Thus, when the transporter 12 uses the safety fence transporting jig 20, the transporter 12 holds the grip 6 and presses the holding plate 4 in the direction of the waist pad 3, and the gripping handle mounting plate of the safety fence transporting jig 20. 7 and the safety fence support plate 21 generate a compressive force (c). The extension plate 22 is pressed down and stabilized by the safety fence support plate 21 and the safety fence stopper plate 5 by the compression force (c).
