Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spiral spring chain, and more particularly to a spiral spring chain that is composed of a large number of spiral springs connected in series and that combines the torques generated by each spiral spring.

Two steel strip spiral springs A coaxially supported on a support shaft
, when B is viewed from a position other than the middle of both spiral springs, such as the end of the support shaft, one spiral spring A has a steel strip wound counterclockwise around the center, while the other spiral spring has a steel strip wound counterclockwise around the center. If both spiral springs A and B have different winding types, such as spring B having a copper band wound clockwise around the center, use appropriate fittings to connect both spiral springs. The centers of the spiral springs A and B as well as the outer ends of the copper strips can be connected in series. When they are connected in series, it means that they are connected so that the winding tightening (energy injection) and unwinding (energy release) of each spiral spring A and B are accumulated.

An object of the present invention is to connect a plurality of spiral springs in series one after another by taking advantage of the fact that two spiral springs with different winding types can be easily interconnected, and to synthesize the torque generated by each spiral spring. The goal is to obtain a chain that can be used.

According to the present invention, at least three spiral springs made of copper strips of the same size are arranged coaxially on the support rod, and the spiral springs numbered 1 and 3 from one end of the support rod are arranged on the support rod. A bottle and two spiral springs are made of the same winding form, such as a steel strip wound counterclockwise around the center when viewed from the opposite end, and a bottle and two spiral springs are made of a steel strip wound clockwise around the center. The spiral springs of spears 1 and 1 and 2 connect the center parts to each other through the joint fittings, and the spiral springs of 12 and 3 connect the outer ends to each other. A spiral spring chain is obtained which is characterized by

Now, an embodiment of the apparatus of the present invention will be described below with reference to the accompanying drawings.

Referring to Figure J-1, a horizontally placed support rod 5, first spiral springs 1, 3, 2 spiral springs 2, and a third spiral spring 3 are coaxially arranged on the support rod 50. It is shown.

When viewed from the right end of the support rod 5, the O.1 spiral spring 1 includes a steel strip 1x spirally wound in a counterclockwise direction around a centrally located inner end ring IA, and the outer end of the steel strip 1x is A ring IB is provided which is fitted into a stopper pin 4 on the bulkhead 11, which will be described below, and a spiral spring 2 is a steel strip spirally wound in a clockwise direction around a centrally located inner end ring 2A. 2x, and the outer end 2E of the steel strip 2x [is the opening 2
7, the i-3 spiral spring 3 is provided with a steel strip 3x spirally wound counterclockwise around a centrally located inner end ring 3A, and a joint fitting 7 is provided at the outer end 38 of the steel strip 3x. is installed.

The tubular joint fitting 6 attached to the partition wall 12, which will be described below, is fitted into the outer ll1llvc of the support rod 5, and the left end is connected to the inner end ring I of the spiral spring 1 as described above.
It is fixed to the inner end ring IA by an AVc fitting set screw 23α. Further, the right end of the joint fitting 6 is fitted into the inner end/gug 2A of the second spiral spring 2, and fixed thereto by a set spuffle 23b. In this way, spear 1
and spiral springs 1, 2 of the fangs 2 connect the inner ends to each other.

2.3 The rectangular joint fitting 7 attached to the outer end 1'12 of the spiral spring 3 has its left half overlapped with the outer end 2B of the second spiral spring 2, and the opening lower A is aligned with the opening 27 and riveted. Ru. In this way, the third spiral spring 3 connects the outer end to the outer end 2 of the second spiral spring 2.
8, the inner end ring 3A is fitted on the outside of the support rod 5, and is locked to the support rod 5 by the locking protrusion 22 on the support rod 5.

The connection of the second and third spiral springs 2 and 3 by the joint fitting 7 is because when the support rod 5 is rotated clockwise AK, the third spiral spring 3 is tightened and at the same time the second spiral spring 2 is also tightened from the outside. Accumulate the tightening of A-2 and the third spiral springs 2 and 3. Also, when the second and third spiral springs 2 and 3 are released from the fully tightened state, the first and third spiral springs 3
rotates the support rod 5 in the counterclockwise direction, but the unwinding motion of the second spiral spring 2 acts via the third spiral spring 3 to promote rotation of the support rod 5 in the counterclockwise direction B.

In other words, the joint fitting 7 connects the spear 2 and the third spiral spring 2.
and 3 outputs are combined. Note that the support rod 5-5 also serves as an output shaft. The joint fitting 6 is also fang 1
Not only does the winding of the spiral springs 1 and 2 of 2 and 2 be performed simultaneously so that the winding of both springs is accumulated, but also the unwinding of both spiral springs 1 and 20 is performed at the same time. It acts to accumulate rewinding.

Therefore, 3 connected in series from joint fittings 6 and 7vc
The spiral springs 1, 2 and 3 serve as support rods and output 111115
You can add the synthesized output to

It is also possible to arrange a desired number of spiral springs on the right side of the third spiral spring 3 in FIG. 1 to obtain a chain body consisting of three or more spiral springs. A disk-shaped partition wall 12 is fitted on the outside of the joint fitting 6 to separate the spiral springs 1 and 2 of the spear 11 and 2, and is provided with a cylindrical flange 15 surrounding the first spiral spring 1. Similarly, a partition 13 is provided intermediate the two spiral springs 2, 3 with seven cylindrical lugs 16, 17 which each surround the spiral springs 2, 3 of the spears 21-'l'3. A partition wall 11 is provided on the left side of the spiral spring 1, and the above-described stopper bottle 4 is attached to the partition wall 11.
A partition wall 14 is placed on the right side of the spiral spring 3. Although these partition walls 11, 12, 13, and 14 are not shown, the spear 1. J-2, 31A3 spiral spring 1゜2.
It is mounted inside a casing which houses a chain 10 consisting of three parts.

Figures 2, 3 and 4 show an example of application of the device 10 of the present invention, which is used as a drive source for a propeller 9 of a toy airplane. It is attached to the boss portion 19. A support rod 5 is rotatably fitted into a bore 30 provided at the center of the boss 19.

Three spiral springs 1, 2, and 3 degrees of the fang 1 and four partition walls 11, 12, 13, and 14 are mounted on the support rod 5 in a tight combination. A ratchet mechanism 24 for determining the position of the stopper pin 4 is attached to the left side of the partition wall 11. A speed reduction mechanism 21 is disposed on the upper right side of the partition wall 14, and includes a gear train meshing with a gear wheel 29 attached to the support rod/output shaft 5. A propeller shaft 8 has one end connected to a pinion 30 located at the end of the gear train, and a propeller 9 is attached to the right end thereof.

In use, the three spiral springs 1, 2, . After fully winding the propeller 9, the three spiral springs 1, 2, and 3 start unwinding at the same time, causing the output shaft 5 to rotate. The rotation of the output shaft 5 is decelerated by the deceleration mechanism 21 and transmitted to the propeller shaft 8.

As shown in FIG. Since the outputs of the three spiral springs 1°2 can be combined. Moreover, the three spiral springs assembled can have a three-dimensional spread.
