Abstract

(57) [Summary] In a conventional luggage fixing device, when assembling, a pivot pin of a lower arm, a pivot hole of an upper arm, and a pivot hole of a torsion spring coincide with each other. Although it is necessary to penetrate through the hole, it is difficult to match the hole due to the spring force after bending and incorporating the torsion spring, and there is a disadvantage that it takes time to assemble the pivot pin. SOLUTION: In the luggage fixing device of the present invention, a long hole is provided in a bottom wall of a lower arm or an upper arm, and one end of the torsion spring is separated from the long hole without bending the torsion spring when the pivot holes match. The pivot pin can be inserted into the pivot hole of the torsion spring while projecting outward. An inwardly protruding projection is provided between the edge of the elongated hole and the arm with which one end of the torsion spring is engaged. A rod-shaped insertion member having a clamping portion for clamping one end of a torsion spring at one end thereof for inserting one end of the outwardly projecting spring into the arm, or a piston having an inclined head end surface and its attachment. An insertion member consisting of a force cylinder is used.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luggage fixing device, and more particularly to a luggage fixing device for mounting and fixing skis or snowboards.

[0002]

2. Description of the Related Art FIGS. 6 and 7 show a conventional luggage fixing device, wherein 1 is a system bar fixed to the roof of a vehicle via legs (neither is shown), and 2 is a system bar. A lower arm 4 having both ends fixed via fasteners 3 is rotatably pivotally connected to one end of the lower arm 2 via a pivot pin 5 so as to clamp a ski or the like between the lower arm 2 and the lower arm 2. The upper arm, which supports the other end and can be locked to the other end of the lower arm 2, is connected to the pivot pin 5.
The center portion of the torsion is rotatably supported, and its one end 6a and the other end 6b are engaged with the upper arm 4 and the lower arm 2 to urge the upper arm 4 to be always open with respect to the lower arm 2. A spring 7 is a locking device for integrally locking the other end of the lower arm 2 and the other end of the upper arm 4, 8 is an operation button thereof, and 9 is a pivot pin 1.
The lock rods 11 and 12 pivotably supported by the operation button 8 and rotatably supported by the operation button 8 are respectively connected to the lower arm 2.
And a cushion provided on the lower surface of the upper arm 4 opposed to the upper surface.

[0003] Since the conventional luggage fixing device has the above-described structure, the assembling of the lower arm 2, the pivot pin 5 for pivotally supporting the upper arm 4, and the torsion spring 6 must be performed first. The pivot pin 2 can be inserted into a pivot hole 2a provided at one end of the lower arm 2 into which the pivot pin 5 is inserted and a pivot hole 4a provided at one end of the upper arm 4. The two ends 6a, 6b of the torsion spring 6 are maintained while maintaining this state.
The torsion spring 6 is pushed between the lower arm 2 and the upper arm 4 while narrowing the angle between the two, and when the holes 2a, 4a and the central pivot hole 6c of the torsion spring 6 are all aligned, the pivot pin 5 Through the holes 2a, 4a, 6c.

[0004]

However, the torsion spring 6 resists the spring force of the lower arm 2
It is extremely difficult to align the pivot hole 6c at the center with the pivot holes 2a, 4a of the lower arm 2 and the upper arm 4 in a state of being inserted between the lower arm 2 and the upper arm 4. However, there was a drawback that it took.

The present invention has been made to eliminate the above disadvantages.

[0006]

The luggage fixing device of the present invention comprises:
A lower arm, an upper arm having one end rotatably supported on one end of the lower arm via a pivot pin, and an upper arm rotatably supported on the pivot pin, and one end and the other end of the upper arm are respectively A spring that engages with the arm and the lower arm and urges the two to be always opened, and that releases one end of the spring that engages with one of the lower arm and the upper arm to the outside. Has holes.

A projection is formed between the elongated hole and an arm that engages with one end of the spring.

The projection has a triangular cross section.

Further, the luggage fixing device of the present invention further has an insertion member for inserting one end of a spring protruding outward of one of the lower arm and the upper arm into the inside.

[0010] The insertion member is a rod having a clamping portion for clamping one end of a spring at an end thereof.

[0011] The insertion member includes a piston having an inclined end face and a biasing cylinder thereof.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

In the present invention, as shown in FIG. 1, an elongated hole 13 is provided in the bottom wall 2b of the lower arm 2 to which one end 6a of the torsion spring 6 is abutted, and as shown in FIG. One end 6a of the torsion spring 6 can protrude outside the bottom wall 2b of the lower arm 2 through the elongated hole 13 in a state of being inserted between the lower arm 2 and the upper arm 4.

Since the luggage fixing device of the present invention is constructed as described above, when assembling the lower arm 2, the upper arm 4, the pivot pin 5, and the torsion spring 6, as shown in FIG. The one end 6a of the spring 6 is
3 so that the spring force of the torsion spring 6 does not work.
a and a torsion spring 6 in the pivot hole 4a of the upper arm 4.
The pivotal holes 6c of the lower arm 2 are aligned with each other, and the pivotal pins 5 are inserted into these holes. Then, as shown in FIG.
b, the one end 6a of the torsion spring 6 is pressed against the spring force by using a rod 14 having a head portion formed in a Y-shape, and is pushed into the lower arm 2 through the elongated hole 13; Next, if the rod 14 is tilted to move the one end 6a of the torsion spring 6 so as to rest on the bottom wall 2b of the lower arm 2, the assembly of the torsion spring 6 can be completed.

The rod 14 has a Y-shaped head whose one leg is shorter than the other leg.
The work of tilting 4 and removing one end 6a of torsion spring 6 from the head of rod 14 becomes easy.

Also, instead of using the rod 14,
A piston 15 having an inclined head end face as shown in FIG.
By using a piston cylinder 17 composed of a cylinder 16 for biasing the piston 15 and moving the piston 16 upward, the one end 6a of the torsion spring 6 may be pushed.

The long hole 13 and the one end 6a of the torsion spring 6 are engaged with each other so that the one end 6a of the torsion spring 6 does not protrude from the long hole 13 to the outside again as shown in FIG. An inwardly projecting projection 18 may be provided between the bottom walls 2b of the lower arms 2 to be formed. In this case,
One end 6a of the torsion spring 6 can be easily connected to the lower arm 2.
Preferably, the protrusion 18 has a triangular cross section so that it can move on the bottom wall 2b, and the width of the upper end is reduced.

The elongated hole 13 may be provided in the upper arm 4 without being provided in the lower arm 2, and the other end 6b of the torsion spring 6 may be projected outward.

[0019]

As described above, according to the luggage fixing device of the present invention, the pivot pin can be easily incorporated, and the torsion spring can be easily incorporated by using an insertion member such as a rod. There is a great advantage that the assembling time and the assembling process can be shortened and automation can be achieved.
