For example, as shown in FIG. 8, the work part 2 inserted below the heavy object is detached from the handle part 1 to remove the heavy object. It can also be used alone as a wedge by removing the handle 1 so that the moved state can be maintained.

  Specific embodiments of the present invention will be described with reference to the drawings.

  The present embodiment is a rescue bar having a working portion 2 having a sharp tip at the tip of the handle portion 1.

  Hereinafter, each component according to the present embodiment will be described in detail.

  The handle portion 1 is a hollow structure made of a circular tube having a cross-section formed of an appropriate metal member (aluminum) as shown in FIGS. A recess 3 is provided to detachably fit and connect the portion 4.

  As shown in FIGS. 4 and 5, the concave portion 3 includes a hollow hole portion 3 a of the handle portion 1, and a large-diameter hole portion provided on the distal end side of the hollow hole portion 3 a and having a larger diameter than the hollow hole portion 3 a. 3b, and when connecting the working portion 2 described later, the large-diameter convex portion 4a of the working portion 2 is fitted into the large-diameter hole portion 3b, and the small-diameter convex portion 4b is connected to the hollow hole portion 3a. Are fitted.

  Moreover, the hole 1a is provided in the peripheral surface opposing position of the site | part in which the large diameter hole part 3b is provided in the front-end | tip part of the handle part 1. As shown in FIG.

  This hole 1a is a fastening hole for inserting a fastening rod 7 described later.

  Further, the handle portion 1 is provided with a fine uneven portion 1b (knurl) on the peripheral surface, and is configured as a non-slip portion.

  As shown in FIGS. 1 to 3, the working unit 2 is a rectangular column having a rectangular cross section formed of an appropriate metal member (steel), and the distal end of the working unit 2 extends from the upper surface to the lower surface. An inclined surface 2b that is inclined in the lateral direction is formed, and the upper edge of the distal end portion of the working unit 2 is formed in a shape that warps upward.

  In addition, as shown in FIGS. 4 and 5, the working unit 2 is provided with a convex portion 4 having a circular cross section at the base end portion, specifically, a large-diameter convex portion 4 a and a large-diameter convex portion. 4a is formed with a small-diameter convex portion 4b projectingly provided, and when connecting to the handle portion 1 described above, the large-diameter convex portion 4a is fitted into the large-diameter hole portion 3b of the handle portion 1, The small-diameter convex portion 4b is configured to fit into the hollow hole portion 3a.

  Further, the large-diameter convex portion 4a is provided with a hole 4c in a penetrating state, and this hole 4c is provided so as to match the hole 1a of the handle portion 1 when the convex portion 4 is fitted into the concave portion 3. The fastening rod 7 can be inserted into the matched hole.

  The connection between the handle portion 1 and the working portion 2 is completed by preventing the fixing rod 7 inserted through the matched hole from being removed by the retaining member 7a.

  Further, a concave groove 2a is provided in parallel on the upper surface of the working portion 2, and a numerical value is assigned to a position near the concave groove 2a.

  The concave groove 2a exhibits an anti-slip function when the heavy object 20 is moved when the heavy object 20 is moved, and the numerical value is a depth position at which the depth at which the working unit 2 is inserted is known. Serves as a display.

  Further, in this embodiment, as shown in FIG. 6, a hammer portion 5 and a punching portion 6 such as pickaxe or ice ax are detachably provided at the distal end portion of the handle 1 in place of the working portion 2. Each of the hammer portion 5 and the turn portion 6 is provided with a convex portion having the same structure as the convex portion 4 for connecting to the concave portion 3 of the handle portion 1.

  Since the present embodiment is configured as described above, for example, when lifting and moving a heavy object 20 such as rubble or a collapsed building in a disaster, the working part 2 is inserted below the heavy object 20 and the working part 2 is operated. The weight 20 is lifted and moved downward with the position in the vicinity of the working part 2 as a fulcrum and the handle part 1 as a power point (see FIG. 7).

  In the present embodiment, since the grip portion 1 is a hollow structure, it is extremely lightweight, and therefore, it is convenient to carry and also has good workability when lifting and moving the heavy object 20.

  In this embodiment, the handle part 1 and the work part 2 are detachable. For example, as shown in FIG. 8, the work part 2 inserted below the heavy object 20 is removed from the handle part 1 and the weight is removed. The handle 20 can be kept in a moving state, for example, by removing the handle 1 so that it can be used alone as a wedge. Moreover, if a plurality of working parts 2 are prepared, various usage methods are possible.

  Further, in the present embodiment, the distal end portion of the handle portion 1 is provided with the recess portion 3 that allows the base end portion of the working portion 2 to be detachably fitted and connected. Will be obtained.

  Further, in this embodiment, the handle portion 1 is circular in cross section, so that it has excellent strength, and is easy to grip and has very good workability.

  Further, in this embodiment, the working portion 2 is a prismatic body, and the distal end portion has a sharp shape formed with an inclined surface 2b inclined in the proximal direction from the upper surface to the lower surface, and thus has excellent strength. In addition, the insertion work can be easily performed.

  Moreover, since the upper edge of the front-end | tip part of the operation | work part 2 warps upwards in a present Example, many heavy objects 20 can be moved by few operations of the handle part 1. FIG.

  In addition, the present embodiment is excellent in versatility because it is provided with a hammer portion 5 and a turning portion 6 such as pickaxe and ice axel in place of the working portion 2 and is very convenient.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
