The present invention relates to an automatic unfolding mass production by using a coil spring to stretch the mass by the stretching force of the coil spring.

에 맡아 축소시킨 나선스프링이 상호관련하여 작동하고 중간개폐구에 회전이 가능하게 부착된 지(支)살 및 외관상단의 외관개폐구에 회전이 가능하게 부착된 받침살을 통하여 상부 내관을 외관의 상단으로부터 돌출시키면서 상기내관에 고착시킨 상부개폐구에 회전이 가능하게 부착시킨 양산 기간살을 충분히 펴서 자동으로 양산을 펴는 동시에 각 양산기간살과 하부접동 개폐구의 사이에 연결한 탄성 펴는 살을 만곡하여 복귀력을 축세(畜勢)하고 이와같은 양산을 편상태로부터 하부내관에 부착한 튀김쇠를 압압하면 이 튀김쇠에 설치된 걸림클릭에 의한 외관의 걸림이 풀려서 이 외관이 상기 탄성버팀살의 탄성력, 즉 만곡된 탄성버팀살이 신장할 때에 생기는 복귀력에 의해서 상동하고 상부내관을 상대적으로 외관내에 양산기간살을 자동적으로 양산을 접는 구조로 되어 있다.This type of automatic unfolding mass production can be mass-produced in a single operation called the pressing of a frying iron, and the so-called mass production is easy to spread. There was a drawback that great force was needed to push down the door. Therefore, the present applicant developed mass production of JP 52-22298 to solve the above-mentioned shortcomings. As is apparent from the publication of this publication, the bag tube is combined with three inner tubes of the upper, middle, and lower parts with respect to one external appearance, and the upper end of the upper inner tube is protruded from the upper end of the external mass production period. Compression spiral springs and exteriors, which secure the mass openings by fixing the upper openings and doors that rotatably support the flesh and protruding the lower end of the lower inner tube from the lower end of the outer tube. Clearance of intermediate opening and closing of up and down movement

The upper inner tube is moved from the top of the exterior through the reduced spiral springs that work together in relation to each other and that the rostrum is rotatably attached to the middle opening and the support rotatably attached to the exterior opening of the upper exterior. While protruding, fully open the mass production period attached to the upper opening which is fixed to the inner tube so as to be rotated automatically, and automatically spread the mass production. When the squeeze and mass production is pushed down and the frying iron attached to the lower inner tube is pressed, the external locking by the locking click installed on the frying iron is released. It is homogenized by the return force generated when the brace extends and the mass production period is automatically generated within the exterior of the upper inner tube. Is an acid upon folding structure.

However, in the automatic mass production of JP-A-52-22298, when the elastic brace is returned to its original state from the curved state by using the elastic brace curved in an arc in the open state as described above. Since the mass production was automatically made by using the return force of the mass, there was a problem that the structure of the mass production was complicated and the weight increased.

The present invention has been made to solve such a problem.

As a means to solve this problem, when the frying iron is pressed in an estimated state, the homology of the exterior is performed by a spiral spring for waste acid interposed between the upper inner tube and the middle inner tube.

When the mass production is unfolded, the waste acid spiral spring is compressed, and when the frying iron is pressed, the waste acid spiral spring is stretched, and the mass is automatically folded by homologizing the appearance.

EXAMPLE

Next, embodiments of the present invention will be described with reference to the drawings.

The mass production bag is fitted with three short inner tubes 2, 3 and 4 of the upper, middle and lower parts with respect to one long outer tube 1 so that the upper end side of the upper inner tube 2 can be The long hole which fixed the upper opening / closing part 6 which protruded from the upper end and attached the mass production period 5 so that rotation was possible, and laid the pin 7 which penetrated and stuck to the exterior 1 in the longitudinal direction of the upper inner tube 2. Insert into (8) to move the upper inner tube (2) straight up and down. The lower end of the lower inner tube 4 protrudes from the lower end of the outer shell 1 and is inserted into the center hole of the bag 9. The middle inner tube 3 is disposed in the outer shell 1 and the upper end of the lower inner tube 4. Compression-extension freely encloses the spiral spring 10 in between. The exterior opening / closing opening 11 is fixed to the upper end of the exterior 1 as a pin 7, and the support bar 13 between the exterior opening and closing opening 11 and the attachment collar 12 which stuck to the center part of the mass production period 5 is supported. ). In addition, between the middle opening 14a of the upper end of the customs clearance 14 inserted into the exterior 1 and the extraction collar 15 attached to the suitable position which is close to the exterior opening 11 of the base 13, 16) and lay the long holes (17, 17) on both sides of the customs clearance 14, and at the same time, install the long holes (18, 18) that coincide with the long holes (17, 17) in the exterior (1). Both ends of the pin shaft 19 penetrating at a position close to the upper end of the (3) protrude out of the customs clearance 14 through the long holes 17 and 18, and are fixed through the ring 20 fitted to the customs clearance 14, The spiral spring 21 is placed on the outer surface between the ring 20 and the intermediate opening and closing 14a. In addition, the fitting tube 23 of the lower sliding opening 22 is fitted to the exterior of the clearance 14 to be attached to the lower locking opening 22 and the extraction collar 12 of the mass production period 5. A brace 25 is attached between the extraction fittings 24. The pin shaft 27 protruding between the long holes 26 and 26 installed in the lower Gagai of the central inner tube 3 penetrates the core tube 28 which moves up and down inside the central inner tube 3, 28. A guide guide 29 is fixed to the lower end of the center 28 and penetrates through the central hole of the left ring 30 of the lower end of the central inner tube 3 so that the guide core side 29 is lowered along the center line of the exterior 1; Spiral spring inserted into the exterior 1 between the left ring 30 and the left body 32 by integrally connecting to the left body 32 fixed as the pin shaft 31 to the inner upper end of the lower inner tube 4 vertically. (10) is entrusted with the outer periphery of the core shaft (29). Attached to the side of the handle tube 23 of the lower sliding opening (22) so that the stiffener 33 is rotatably attached, the stiffener (33) is pressurized as a spring 34 to click the end portion (33a) Through the through hole of the handle tube 23 in the small hole (1a) laid in the vicinity of the lower end of the exterior (1) to be caught.

Long hole 16 which laid down the locking click 35a of the deep-fried iron 35 built in the lower inner medicine 4 below the small hole 1a of the exterior 1 through the long hole 36 of the lower inner pipe 4. A squeeze presser protrusion 35b having an outer surface as an inclined surface at the lower end of the scoop bar 35, and this is formed into a long hole 36 of the lower inner tube 4 and a lower hole of the lower part of the outer case 1 ( It protrudes in the dividing groove 23a of the lower end of the handle pipe 23 through 1c). In addition, an annular hole (37) centered on the lower inner tube (4) is formed at the upper end of the bag (9), and the annular hole (37) is provided by inserting a spring (38) into the annular hole (37). By pushing up the lower end of the central circular pipe 39a of the live tennis ball 39 attached to it, the live tennis ball 39 is homogenized to connect the end of the mass production period 5... 5. And 40 is a waste spring spiral spring interposed between the upper inner tube (2) and the middle inner tube (2) to automatically fold the mass production. The spiral spring 40 is divided into two sizes, so that the small spring 40a penetrates the pin 7 attached to the exterior 1 and the pin 41 penetrates the lower end of the upper inner tube 2. It is remodeled in between. Moreover, the larger spring 40b is interposed between the pin 41 and the pin shaft 19 which penetrated at the position near the upper end of the middle inner tube 3.

Next, the operation of the mass production configured as described above will be described.

When the live tennis 39 is pushed down against the elasticity of the spring 38 from the folded mass production position shown in FIGS. 1 and 4, the load of the tip of the mass production period 5… 5 by the live tennis 39 is pushed down. The mass production period (5… 5) is released to a small state.

Pressing the latch 33 of the handle tube 23 in this state allows the free extension of the spiral springs 10 and 21 compressed by the click end portion 33a out of the small holes 1a of the exterior 1 to be compressed. do. And the pressing of the latch 33 is carried out in the state of holding the bag (9), so the position of the lower inner tube (4) is fixed at the same time as the hook (35a) of the claw (35) is caught in the appearance (1) ), The position of the) is also fixed, so that the distance between the left ring 30 and the left body 32 in the outer shell 1 is enlarged by the extension of the spiral spring 10 to push the inner tube 3 up against the outer shell 1. Simultaneously with this, the spiral spring 21 placed on the outer circumference of the clearance 14 is also extended, but the pin shaft 19 fixed to the ring 20 which catches the lower end thereof is fixed to the inner tube 3 so that the ring ( 20, when the homogeneous force of the spiral spring 10 and the lowering force of the spiral spring 21 are applied to balance the elasticity of both, the extension of the spiral spring 10 is stopped and the spiral spring 21 is stopped. The stretching force of the only acts in the direction of pushing the clearance 14 and the intermediate opening and closing 14a along the appearance (1), and when the extension of the spiral spring 21 is attenuated (다시), the spiral spring (10) again The force of the pushing direction is applied by) so that the two spiral springs 10 and 21 extend the bag tube in relation to each other. Accordingly, as the intermediate opening 14a approaches the exterior opening 11 of the upper end of the exterior 1, the ground meat 16 is sufficiently spread and at the same time, the support 13 is rotatably attached to the exterior opening 11. ) And the upper inner tube 2 is pushed up by the middle inner tube 3 so that the upper inner tube 2 protrudes from the upper end of the outer tube 1 along the long holes 8 and 8, The gap between the upper opening and the upper opening (6) is to extend the mass production period (5… 5). In this case, the pin shaft 19 and the pin shaft 19 together with the central inner tube 3 are equal to each other, so that the distance between the pin shaft 19 and the pin 7 fixed to the exterior 1 is reduced, so that these pin shafts 19 and the pins are reduced. The waste acid spiral spring 40 interposed between (7) is compressed so that the homogeneous force of the external appearance at the time of folding | folding a mass production is accumulated. Then, the transition from the open state to the folded state is performed by moving the live tennis ball 39 toward the fry iron 35. That is, when the live tennis 39 is raised, the upper end of the original tube 39a of the live tennis 39 comes into contact with the inclined surface of the projection 35b of the fries 35 to push the fries 35 down. Since the locking click 35a deviates from the long hole 1b of the exterior 1 and the engagement of the exterior 1 by the locking click 35a is released, the exterior 1 is formed of the pin side 19 and the pin 7. It rises along the lower inner tube 4 by the stretching force of the waste acid nasan spring 40 compressed therebetween. Since the upper part of the exterior (1) is relatively the upper inner tube (2) to move down inside the exterior (1), the spacing between the upper opening (6) and the exterior opening and closing opening (11) by reducing the mass production period (5… 5) With this, the support 13 is pivoted and the central opening 14a and the clearance 14 are pushed down to the lower ends of the long holes 18 and 18 according to the appearance 1 through the grate 16, and also the props. The lower sliding opening 22 and the handle tube 23 are pushed down to the position shown in FIG. 3 through the 25, and the click end portion 33a of the latch 33 of the handle tube 23 is the exterior (1). The small pores 1a are caught, but the spiral springs 10, 21, and 40 are not compressed yet and are in a stretched state.

Next, when the tip of the upper inner tube (2) is held from this state and the bag 9 is pressed, the lower inner tube 4 is the same and the locking click 35a of the frying iron 35 is opened (1). Coupling to the long hole (1b) of the) and at the same time the projection 35b is fitted in the dividing groove (23a) of the lower end of the handle pipe 23 and is homogenized until it is hidden in the protective cover (23b) in between The pin shaft 19 which penetrates the middle inner tube 3 by compressing and condensing the spiral spring 10 interposed between (3) and the lower inner tube 4, and being pressurized by the spiral spring 10. Press the ring 20 to push up the ring 20 along the long holes 17 and 17 of the tubular opening 14 and the long holes 18 and 18 of the exterior 1 to compress and condense the spiral spring 21 to the first degree chain. The state is a little open, and the concentration of the end of the mass production period (5… 5) in the live tennis (39) is a fully folded mass production state indicated in the first line.

In addition, in the embodiment shown in the drawing, the spiral spring 40 for waste acid is divided into two sizes, and the small spring 40a is pinned to the exterior 1 (1) and the upper pin 7 and the upper inner tube 2. Of the pin shaft 19 interposed between the pin 41 fixed through the lower end of the pin and the large spring 40b penetrated at a position near the upper end of the pin 41 and the central inner tube 3. However, it is designed to be installed in between, but this prevents interference and grazing between the outer circumferential surface of the waste acid spiral spring 40 and the inner circumferential surface of the upper inner tube 2 and the middle inner tube 3 inserted therein, and prevents the grazing of the spiral spring 40. In order to exhibit elasticity more effectively, the spiral spring 40 may be one.

The upper part of the appearance when the frying iron is pressed in the state where the mass production is opened, the automatic folding of the mass production is performed by the spiral spring interposed between the upper inner tube and the middle inner tube. This can simplify the structure of the flesh and reduce the weight of the mass.
