Abstract

PROBLEM TO BE SOLVED: To connect each connection rod and a point fitting in a single operation without using a butterfly nut to immediately use the same by respectively providing a connecting part of each connection rod and each point fitting with a connection shaft part to be fitted into an insertion hole, and a recessed part for locking a central connection part of a locking member on an outer peripheral surface of the connection shaft part. SOLUTION: When a mace rod is used, a point of a connection rod 1A is inserted into a basic end connection shaft part 4a of another connection rod 1B, a point of this connection rod 1B is inserted into the basic end connection shaft part 4a of another connection rod 1C, and further a point of this connection rod 1C is inserted into the basic end connection shaft part 4a of a point fitting 10, whereby a long mace rod can be easily assembled. On this occasion, on each connection part, a central connecting part of a locking member 3 is fitted in a locking recessed part 7, and a notch 9 is engaged with a jam pin 8, so that the rods can be surely connected without relatively rotating the connection rods 1A-1C. That is, the connection rods can be connected in a single operation without using the butterfly nuts, so that it can be immediately used as a long bar for emergency rescue tool.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disaster relief rescue stick used as a long bar for an emergency rescue tool, for example.

[0002]

Conventionally, there is a long bar of the split type which is connected and assembled as a rescue rescue stick of this kind. However, since the wing nut is used in the connecting portion, the wing nut is damaged or lost. Often occur and become unavailable during an emergency disaster.

[0003]

The rescue rescue rod according to the present invention can be connected by a one-touch operation of a fitting type without using a wing nut in the connecting portion, so that the connection by the connection can be performed simply and reliably, so that it can be used immediately. it can.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 One embodiment of the present invention will be described with reference to FIGS. 1 is a side view showing a use state, FIG. 2 is a side view showing a state disassembled from FIG. 1, FIG. 3 is an enlarged side view showing a connecting portion of FIG. 1, and FIG.
FIG. 5 is a side view showing the connecting shaft of FIG.

In the figure, 1A, 1B, and 1C are approximately 600
The three connecting rods made of pipes each having a length of 2 mm are provided at the leading end sides of the connecting rods 1A to 1C, respectively, and the openings are opened laterally in the direction orthogonal to the longitudinal direction. The left and right long and short legs 3b, 3c having a substantially U-shape so that the U-shaped central connecting portion 3a is pressed inward.
The lock members 4 each having a substantially U-shape whose base ends are rotatably mounted on the rod outer peripheral surface are respectively inserted into and fixed to the base ends of the connection rods 1B and 1C (for example, welding 5).
The connecting shaft 4a of the connecting shaft 4 is inserted into insertion holes 6 formed on the connecting rod tip sides of the connecting rods 1A and 1B. Reference numeral 7 denotes a locking recess provided in each of the connection shaft portions 4a, and the center connection portion 3a of the lock member 3 is locked. Reference numeral 8 denotes a detent pin provided on each of the connection shaft portions 4a, and the connection portions are integrated by being fitted into the notches 9 of the connection rod tip surfaces of the connection rods 1A to 1C (the rotations of the connection portions are prevented). Is done. Reference numeral 10 denotes two end fittings having a plurality of shapes such as a burl shape, each of which has a connecting shaft portion 4a formed on the connecting shaft 4, a locking concave portion 7, and a detent pin 8.

The central connecting portion 3a of the lock member 3 is fitted in the opening 2 and its long and short legs 3b, 3c
Is supported, the central connecting portion 3a is hard to turn and does not come off from the opening 2, and the central connecting portion 3a is pressed inward in the opening 2. Therefore, the engagement with the engagement concave portion 7 is strong, so that the connecting rod does not come off from the connecting shaft portion 4a.

In the disassembled state shown in FIG. 2, these can be set together for carrying, and when used, the connecting rod 1A is used.
When the tip of the connecting rod 1B is inserted into the base connecting shaft portion 4a of the connecting rod 1B, it stops at "snap". When the tip of the connecting rod 1B is inserted into the base connecting shaft portion 4a of the connecting rod 1C, it stops at "snap". When the base connecting shaft portion 4a of the tip metal fitting 10 is inserted in front of the end, the snapping stops and a long rod is easily completed as shown in FIG.

In the assembled state shown in FIG. 1, since the central connecting portion 3a of the lock member 3 at the connecting portion does not have its own rotating force but fits into the locking concave portion 7 by the stopping force, the connecting rods 1A to 1C are connected. Since the notch 9 does not come out of the shaft portion 4a and the notch 9 is engaged with the detent pin 8, each of the connecting rods 1A to 1C does not rotate individually. Become.

When disassembling, the central connecting portion 3a of the lock member 3 is slightly lifted by applying force to the tip fitting 10a.
Is pulled out of the connecting rod 1C, and then the central connecting portion 3a of the lock member 3 is slightly lifted with force to connect the connecting rod 1C.
Is pulled out from the connecting rod 1B, and when the central connecting portion 3a of the lock member 3 is slightly lifted with force, the connecting rod 1B comes off from the connecting rod 1A.

Embodiment 2 In the first embodiment, pipes are used as the connecting rods 1A to 1C. However, an insertion hole is provided at the distal end of the rod as the rod, and the connecting shaft 4a is provided at the base end of the rod.
May be protruded.

[0011]

As described above, according to the present invention, the connecting portion can be connected by a one-touch operation without being fitted with a wing nut, so that the connection can be easily and securely connected and the device can be used immediately. Can be
