DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handheld lifting device which is convenient for carrying a heavy object such as a concrete block board.

[0002]

2. Description of the Related Art Conventionally, since the handle bar is simply provided so as to project in the extended state of the gripping arm, the work of attaching the handle bar is troublesome and it is difficult to grip. In addition, when it is detachably installed, its structure becomes complicated, or the handle bar (pipe) removed
There was a drawback of losing.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks, and provides a manual holding-type hoist which allows the handle bar to be easily attached and detached, and which can be easily grasped to efficiently perform hoisting work. .

[0004]

The gist of the present invention will be described with reference to the accompanying drawings. Two handlebars 1 and 1 are provided by two workers, respectively, protruding from the left and right of a manually-held lifting body a. Holding and pulling each to hold the manual holding type lifting body a's holding arm 2
A manual holding-type hoist that holds the object to be lifted b by 2 and hoists it, and fits the handle bar body 1 to the upper end lifting portions 3 and 3 of the left and right holding arms 2 and 3 without rattling. A handle receiving pipe 4 having a matching inner diameter is attached, and the handle rod body 1 is provided in the handle receiving pipe 4 in a fitted state, and the handle receiving pipe 4 is provided near the inner end of the rod-shaped handle 1.1.・ Grip cylinder 6 provided with stopper protrusions 5 ・ 5 to be locked to the inner edge of 4 and to be locked to the outer edge of the handle receiving pipe 4 ・ 4 at the outer edge of the handle bar 1.
The present invention relates to a manual holding-type lifting device characterized in that 6 is fitted and fixed.

[0005]

[Function] The handle bar body 1 having the stopper projections 5 5 projecting from the inner end of the handle bar body 1 1 is inserted from the inside of the handle receiving pipes 4 4 to project to the outside. Since the grip cylinders 6 and 6 are fitted and fixed near the outer end of the body 1.1, the outward movement of the handle rod body 1.1 with respect to the handle receiving pipes 4 and 4 is caused by the stopper projections 5 and 5. It is blocked by the locking action of the handle receiving pipes 4 and 4 on the inner end edge, and the disengagement from the opposite inner direction is blocked by the locking action of the grip cylinders 6 and 6 on the outer edge of the handle receiving pipes 4 and 4. The safety is ensured and there is no loss of the handle bar 1.1.
In addition, the gripping cylinders 6 make it a manual holding type lifting device that is easy to lift.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an example of a preferred embodiment, in which the handle bar body 1.1 is provided on the left and right sides of the manually-held lifting body a.
A manual holding-type lifting device in which two workers hold one by one and lift it to hold the object to be lifted b by the holding arms 2 and 2 of the manually-holding-type lifting body a and hold the left and right holding arms. Handle bar body 1.1 on the upper end lifting part 3.3 of 2.2
Handle receiving pipe 4 with an inner diameter that fits without rattling
・ 4 is attached, and the handle bar 1 ・ 1 is fitted in the handle receiving pipe 4 ・ 4.
1 is provided with a stopper protrusion 5.5 that locks to the inner end edge of the handle receiving pipe 4 near the inner end of 1, and the outer end of the handle receiving pipe 4 is at the outer end of the handle rod 1. The grip cylinders 6, 6, which are locked to the edge, are fitted and fixed. Since the stopper projections 5 and 5 show the case where a screw is adopted, the handle bar body 1 and 1 cannot be removed unless the screw is removed. The grip cylinders 6 and 6 are made of rubber and fixed by press fitting, but an adhesive may be used together.

The handle bar 1 having the above structure
・ The outer end of the handle bar 1.1 that is inserted from the inside of the handle receiving pipe 4, 4 by inserting the handle bar 1.1 in which the stopper protrusions 5 are projected from the inner end of 1. Since the grip cylinders 6 and 6 are fitted and fixed to the part side, the outward movement of the handle rod body 1 with respect to the handle receiving pipes 4 and 4 causes the stopper protrusions 5 and 5 to move the handle receiving pipes 4 and 4 respectively. Blocked by the locking action on the inner edge,
The disengagement from the opposite inner direction is prevented by the locking action of the grip cylinders 6 and 6 on the outer edge of the handle receiving pipes 4 and 4 to ensure safety, and the handle rod body 1 can be removed and lost. Without such a situation, the manual holding type lifting device is easy to lift by the grip cylinders 6 and 6.

In the figure, reference numeral 7 is a holding piece, 8 is a holding piece,
Reference numeral 9 is a pivot portion.

[0009]

EFFECT OF THE INVENTION Since the manual holding type hoist according to the present invention is constructed as described above, it becomes a stable handle attachment mechanism in which the handle rod does not slide in either direction with respect to the handle receiving pipe, and the handle rod is provided. A hand-held lifting device that does not lose its body and is very easy to hold due to the attachment of a grip cylinder and can improve the efficiency of lifting work accordingly.

Claims (1)

(57) [Claims] 1. A hand-held lifting body is provided with two handlebars projecting from the left and right sides of the handheld lifting body, and each of the two workers lifts the handlebar body by one hand and holds the object to be lifted by the holding arms of the handheld lifting body. It is a manual holding type hoist that raises the left and right holding arms by attaching a handle receiving pipe with an inner diameter to the upper end lifting parts of the left and right holding arms so that the handle rod can fit without rattling. In this state, a stopper protrusion that locks to the inner edge of the handle receiving pipe is provided near the inner end of the rod handle, and a grip that locks to the outer edge of the handle receiving pipe at the outer edge of the handle rod. A manual holding-type lifting device characterized in that a cylinder is fitted and fixed.
