A spring operating device using a compression coil spring can have a structure as shown in FIGS. 1 and 2. That is, the compression coil spring 1 is mounted between spring receivers 4 and 5 which are respectively fixed to a spring receiver 2 and a rod 3 which is slidably fitted in the spring receiver 2 in the axial direction. The spring receiver 2 is rotatable about the rotating shaft 6, which is pivoted by bearings 8 and 9 fixed to the operating device box 7, as shown in FIG. The rod 3 fixing the spring receiver 5 with the stopper 10 is movable in the axial direction under the force of the spring 1, and the end of the rod 3 is pivotally connected to the outer end of the pivot link 12 by a pin 11. The link 12 is pivotally connected to a support bracket 13 fixed to the device box 7 by a pin 14, and is rotatable about the pin 14. Output shaft 15 concentric with pin 14 (Figure 2)
The lever 16 supported from the operating device box 7 by the lever 16 is rotatable together with the output shaft 15 about the pin 14 and the output shaft 15. Link 1 only when colliding with mating surface 16a or 16b
It is configured to rotate together with 2.

示す状態になる。 Regarding the operation, the link 12 is moved from the position shown in FIG.
When rotated counterclockwise around the pin 14 as shown in FIG.
6a is disengaged, and the rod 3 slides into the spring receiver 2 in the axial direction while compressing the spring 1 via the spring receiver 5. At the same time, the rod 3,
The spring receiver 2 and the spring 1 are rotated clockwise about the rotating shaft 6. As the counterclockwise rotation of the link 12 continues, the spring 1 is further compressed and the link 12 and the rod 3 are compressed as shown in FIG.
When the spring 1 becomes straight and is located on a straight line connecting the center of the pin 14 and the center of the rotating shaft 6, the amount of compression of the spring 1, that is, the stored force becomes maximum. When the link 12 is further rotated in the counterclockwise direction from the state shown in FIG. be rotated. As the link 12 rotates, the drive piece 12a abuts against the engagement surface 16b of the lever 16, so that the lever 16 is then rotated together and the output shaft 15 is also rotated. That is, the output shaft is driven by the force caused by the release of the spring 1. The counterclockwise rotation of the link 12 thus causes the lever 16 to also rotate in the same direction due to the spring force, but this rotation is stopped when the lever 16 hits the stopper bolt 18 screwed into the stopper seat 17. , the state shown in FIG. 4 is reached.

る。 From the state shown in FIG. 4, when the link 12 is reversely rotated clockwise as shown by arrow c, the spring 1 is compressed and stored, and returns to the state shown in FIG. 3 from the opposite direction. When the state is passed, the spring 1 is released and the link 12 is rotated clockwise by rapid rotation, and the drive piece 12a engages the engagement surface 16a of the lever 16.
After the lever 16 and the output shaft 15 collide with each other, the lever 16 and the output shaft 15 are driven clockwise, and when the lever 16 hits the stopper bolt 20 screwed into the stopper seat 19, the rotation of the lever 16, the output shaft 15, and the link 12 is stopped. The state returns to the state shown in FIG. In this manner, the spring operating device rotates the output shaft using the force of the spring, and thereby performs opening/closing operations of opening/closing equipment, etc. The spring receiver 2, the rod 3, and the rotating shaft 6 are members that are rotated in response to the spring's loading and unloading movements.

で、以上の危険が予知できない欠点があつた。 In such a spring operation device, when the spring is in a compressed state, there is a risk that the spring may be released due to vibrations or the like, which may cause an accident during inspection or maintenance. Moreover, in the past, for example, the door 21 (Figs. 1, 3, and 4) of the spring operating device box 7 made it impossible to see the internal spring's loading and unloading movements, so there was a drawback that the above-mentioned dangers could not be predicted. Ta.

ことを特徴としている。 This invention was made in order to eliminate the above-mentioned drawbacks, and the purpose is to provide a spring operating device that can check the amount of energy stored in the spring, and is linked to the compression storage and release movements of the spring. It is characterized by the fact that it has a pointer that moves the pointer, and the amount of energy stored and released in the spring can be determined by the movement of this pointer.

られている。 The invention will be explained below with reference to the illustrated embodiments. Since the members indicated by reference numerals 1 to 21 in FIGS. 5 to 10 are completely the same as the members with the same reference numerals in FIGS. 1 to 4, detailed explanation thereof will be omitted.
In this invention, as shown in FIGS. 5 to 10, a pointer is attached to the spring receiver 2 and the rod 3, which rotate as the spring 1 is loaded and released. 22 and rotate shaft 6.
A name plate 23 having a square hole 23a is provided near the tip of a pointer 22 that rotates around , and a scale 24 is provided along one side of the square hole 23a. Control device box door 2
1 is provided with a window 25 through which the square hole 23a can be seen from the outside.
この考案では、以上のように、指針22を設け

が目盛24に沿つて角孔23a内で動くことによ
つて窓25から目視できる。 In this invention, as described above, since the pointer 22 is provided, when the link 12 is rotated in the direction of the arrow a from the state shown in FIGS. 3 and the spring receiver 2 are rotated in the direction of the arrow d, and at the same time the spring 1 is compressed and stored energy. However, when the spring receiver 2 is rotated in the direction of the arrow d, the pointer 22 attached to it is rotated. It is rotated in the direction of arrow e. The rotation of the pointer 22 can be visually observed through the window 25 as its tip moves along the scale 24 within the square hole 23a.

知りうる。今述べている実施例では第8図に示す
ように、指針22が目盛24の中央に来たとき、
ばね1の蓄勢量は最大となる。 As described above, the energy of the spring 1 is stored until the link 12, the rod 3, and the spring receiver 2 are in a straight line, as shown in FIG. However, since this rotation can be visually observed by the movement of the pointer 22, the amount of energy stored in the spring 1 can be visually determined by the movement of the pointer 22 along the scale 24. In the embodiment just described, as shown in FIG. 8, when the pointer 22 comes to the center of the scale 24,
The amount of energy stored in spring 1 becomes maximum.
第7及び8図のばねの蓄勢量最大の位置を過ぎ

0図に示すように、目盛24の最下端に位置し、
ばね1が放勢し終つたことを示す。 7 and 8, the spring 1 switches to the released state and, as previously described, the spring 1 switches to the released state and the lever 16 is moved as described above.
hits the stopper bolt 18, and the release of the spring 1 ends; however, in the illustrated example, at this position, the pointer 22 is in the first position.
As shown in Figure 0, it is located at the lowest end of the scale 24,
This indicates that spring 1 has finished being released.
以上の実施例では指針22をばね受け体に固着

勢量を表示させてもよい。 Although the above embodiment shows a structure in which the pointer 22 is fixed to the spring receiver, it may also be attached to the rotating shaft 6, or the pointer may be connected to a member that rotates together with the spring 1 through a link or the like. good. Further, the name plate 23 may be colored in place of the scale 24 to display the amount of energy stored in the spring.
以上のように、この考案によれば、ばねの圧
