  Embodiments of a power cord support according to the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram showing a state where an operator supports a power cord using the power cord support tool when a garden tree or the like is trimmed using a hedge clipper that is one of hand-held power tools. . 2A is an enlarged front view of the power cord support, FIG. 2B is an enlarged side view thereof, and FIG. 3 is an enlarged side view showing a state in which the power cord is taken into the space in the frame. In FIG. 1, a fixed-length power cord 3a extending from the clipper body 21 of the hedge clipper 20 is connected to an arbitrary-length power cord 3b via a relay portion 17, and the power cord 3b is provided on the outer wall of the house. Connected to a power outlet. These power cords 3a and 3b are supported by the power cord support 1 that is engaged with the work pants 19 of the worker.

  The power cord support 1 includes an annular frame 5 that holds the power cord 3b in the space in the frame, and a coupling body 7 that is engaged with a work trouser 19 that is a worker's clothes. It is configured to be indirectly connected. The annular frame 5 is formed to be an oval frame by a long belt-like plate material. One of the semicircular portions on both sides of the annular frame 5 is for allowing the power cord 3b to be inserted into and removed from the space in the frame of the annular frame 5 at a position coinciding with the longitudinal central axis of the ellipse. A gap 11 is provided. The gap 11 has a width smaller than the wire diameter of the power cord 3 b in a normal state, and is formed to be expandable by the elasticity of the annular frame 5. In addition, a pair of guide portions 12 that guide the power cord 3b outside the frame to the gap portion 11 are extended at the opposite ends of the gap portion 11 so as to extend outwardly on the outer surface side.

  In addition, a pedestal for maintaining the posture of the annular frame 5 constant when the power cord 3b is taken into the space in the frame from the gap 11 at the end opposite to the gap 11 in the other semicircular portion. 13 is provided. The pedestal portion 13 becomes wider as the distance from the annular frame 5 increases, and is formed in a trapezoidal shape having a pedestal bottom curved in an arch shape. The pedestal bottom surface is orthogonal to the longitudinal axis direction coinciding with the direction in which the power cord 3b is taken into the frame space from the gap portion 11, and is substantially equal to the belt width of the annular frame 5 and has a short width of an ellipse. It is formed so as to define a substantially equal flat surface. A connecting hole 8 through which the connecting body 7 made of a metal ring is passed is formed in the center of the side surface of the base portion 13. Further, the engaging body 6 is configured to include a clip-like holding portion 15 that holds the clothes by folding back one end of a long belt-like plate material. A connecting hole 9 through which the connecting body 7 is passed is provided at the other end of the engaging body 6.

  Next, the procedure for supporting the power cords 3a and 3b by the power cord support 1 will be described. The pruning operator using the hedge clipper 20 first inserts the clamping part 15 of the anchoring body 6 deeply into the upper end of the work pants 19 and holds it. Then, holding the annular frame 5 connected to the anchoring body 6 through the connecting body 7 in one hand, the base of the pedestal portion 13 is applied to the waist of the operator, and the annular frame 5 is placed against the waist contact surface. To stand upright. At this time, it is desirable that the arch shape of the pedestal bottom surface of the pedestal portion 13 matches the arc shape of the abutment surface in that the posture of the annular frame 5 can be most stably maintained constant. In this upright state, the power cord 3b is applied to the gap 11 by the guidance of the guide 12, and the gap 11 is expanded by applying a pressing force that is equal to or greater than the elastic force that maintains the shape of the annular frame 5 to the inside of the frame. Then, the power cord 3b is taken into the space in the frame and held.

  The power cords 3a and 3b supported by the power cord support 1 secure a surplus length portion by detouring from the clipper body 21 to the vicinity of the operator's waist, and the annular frame without dropping from the gap portion 11 due to its own weight. The power cord 3b is held in the space inside the body frame. Further, for example, when an excessive impact load equal to or greater than the elastic force for maintaining the shape of the annular frame 5 is applied to the power cords 3 a and 3 b so as to expand the gap 11, the power cord 3 b is annularly formed from the gap 11. It is instantaneously released out of the frame 5 and the extra length is released, and the support state is released.

  As described above, according to the present invention, the power cords 3a and 3b can be detoured and supported by the operator, and the power cords 3a and 3b can be prevented from being cut by a tool blade such as an operating metal blade. In addition, since the gap 11 is provided in the annular frame 5 so that the power cord 3b can be inserted into and removed from the space in the frame, the power cord 3b can be easily attached to and detached from the annular frame 5 with one touch. be able to. Furthermore, since the guide portion 12 is provided in the gap portion 11, the power cord 3b can be guided to the gap portion 11 along the guide portion 12, and the work of taking in the space in the frame can be simplified. Further, since the pedestal portion 13 is provided on the annular frame 5, the posture of the annular frame 5 can be stabilized during the work of taking the power cord 3b into the space in the frame, and the work of holding the power cord 3b is simplified. Can be.
