The present invention relates to an automatic opening and closing mass production that can automatically operate the mass production and closed acid of one hand.

Conventional mass production can be easily pressed by pressing the button at the time of opening, but when folded, it was inconvenient to hold down with both hands, and moreover, when lifting an object in one hand, it was not inconvenient to fold the mass production.

The present invention is not only to automatically open and close the mass production to improve such inconvenience, but also to be able to operate the opening and closing with one hand as described in detail based on the accompanying drawings as follows.

Springs (6, 6 '…) are installed between the mass (4) and the base (5) of FIG. 1 to be used as a driving force for the waste acid, and to make a ring (21) on the top of the keg (3) and a rope (8). One end of the mass production stand (1) through the movement roller (9) is fixed to hang the rope (8) to the fixed roller (7) installed through the mass production stand on the top of the mass production stand (1) and to move up and down in the mass production stand (1) Secure the other end of the rope 8 to the upper part 20 inside. Connected to the center of the motion roller (9) is inserted into the piston 27 to move up and down inside the mass production stand (1) and attach the link (15) to the bottom and protruding the hanging piece (16) at the bottom.

The spring barrel 14 is fixedly installed at the bottom of the mass production stand 1, and the spring 13 and the spring guide 12 are inserted therein, and the mass production stand 1 is cut in the longitudinal direction to protrude into the mass production stand 1. 26) is installed to move up and down with the insertion spring guide (12). Next, the installed lower button 10 is installed at the lower left of the spring barrel 14, and one end 11 of the spring guide 12 is cooled. Insert the ring (23) at the bottom of the spring barrel (14) and connect it to the link (25) and the lever (24) with the handle (22), and install it to move up and down according to the operation of the lever (24). 23) Install the waste acid button 19 on the lower mass production stand 1 as shown.

As shown in FIG. 1, the mass production can be automatically calculated when the hanging piece 16 is comforted on the protrusion 25 of the spring guide 12 and the lever end 11 of the opening button 10 is comforted together. It is in a state. When the open button 10 is pressed, the spring guide 12 and the link 15 are pulled down together by the force of the spring 13, which is released by pressing the lever end portion 11, and the piston 27 And locomotion rollers (9) also go down to the bottom, so that the barrel (3) is raised by the rope (8), the sunshade will be unfolded. (As in second figure)

Next, when the waste acid button 19 is pressed, the lower portion 17 of the link 15 is pushed, and the comfort sheet 16 is peeled off from the protrusion 26 so that mass production is performed by the waste acid springs 6, 6 ′, 6 ″. It will be folded automatically. At this time, since the state inside the spring barrel 14 is shown in FIG. 3, when the lever 24 is pulled counterclockwise as shown in FIG. 4 for the next estimate, the ring 23 is pushed up by the link 25. The spring guide 12 and the spring 13 are pushed up and compressed so that the hanging piece 16 hangs on the protrusion 26, and the lever end 11 of the estimated button 10 also hangs on the spring guide 12. Then, the next estimate is prepared as shown in FIG.

5 illustrates the correlation between the length of the movement of the flesh barrel 3 (about 40 cm) and the movement distance of the spring guide 12 by the spring 13 (about 10 cm). In FIG. 1 and FIG. 2, only one exercise roller 9 is drawn for convenience of explanation, but several exercise rollers 9, 9 ', 9 " Exercise roller (9) acts as a moving pulley, only half the movement distance of Saltong (3) movement, exercise roller (9 ') is only half of the movement locomotive (9). Therefore, when using the two movement rollers, if the barrel 3 moves about 40cm, the piston 27 may move about 10cm.

7 (a) and 7 (b) show another embodiment of the waste acid springs 6, 6 '.

If the spring 28 is fixed as shown in the drawing 31, the angle between the sunshade 4 and the base 5 according to the opening and closing of the sunshade is changed, so that the sunshade can be folded by the restoring force of the spring 28. In another embodiment, the auxiliary barrel 29 is installed on the upper part of the barrel 3, and the spring 30 is installed therebetween, so that the mass production can be folded with the compressed expansion force during the calculation.

FIG. 7 (c) shows another embodiment of the opening button 10 and the handle 22, and the opening button 10 'is attached to the mass production stand 1 to hang the barrel 3 as the mounting piece 32. FIG. And remove the handle 22 and the spring 25, the link (25 ') to the connecting lever 24' and the ring 23 is an embodiment using the spring barrel 14 itself as a handle.

8 is an embodiment in which a flat tape spring 39 (flat spiral spring) is used instead of the cylindrical spring 13 as a driving force. First, install the rope 48 instead of the link 15 under the piston 27, and hang the rope drum 46 to idle on the shaft 49 and abut the clutch teeth 47, 47 'on the coaxial shaft. The key 43 is inserted into the crutch plate 42 is in close contact with the spring 40, and one end of the shaft 49 is fixed to one end of the plate tape spring 39, and the other end of the spring 39 The pins 37 are fixed to the wheels 36 and are to be tasted with the pawls 38. A handle 35 is attached to one end of the shaft of the wheel 36. Next, the opening link 44 and the closing link 45 are connected to the adjustment knob 34, and one end of the opening link 44 is caught by the stop plates 41, 41 ', which are provided on the circumference of the clutch plate 42. And one end of the waste acid link 45 is installed to be in contact with the inclined surface of the clutch plate (42).

Turn the handle 35 to close the plate tape spring 39 and push the adjustment knob 34 up from the neutral position so that the link 44 is pushed up and the stop plate 41 provided on the circumference of the clutch plate 42. , 41 '…) so that the rope drum 46 is turned and the rope 48 is rolled up and the sunshade is opened. Pushing down the adjusting knob 34 pushes the link 45 down, pushing the inclined surface of the clutch plate 42 so that the clutch plate 42 is pushed to the right so that the clutch teeth 47, 47 '… And the mass production is folded by the waste acid springs 6, 6 '... or 28, 28' ... or 30.

9 shows an embodiment in which a small motor 51 is used as the driving force. The rotation speed is decelerated by the gear box 50, which opens and closes mass production.

It should be noted that in the above two embodiments, when the plate tape spring 39 or the motor 51 is used as the driving force, the degree of mass production can be arbitrarily opened. Conventional mass production is suddenly wide open due to the repulsive force of the spring pressed, so it was not dangerous in places where there are many people. However, since the opening degree of the mass production can be arbitrarily adjusted, such risks can be used without any.

As described above, the present invention can not only fold and fold both hands with one hand, but can also arbitrarily open the mass production when the plate tape spring 39 or the motor 51 is used as a driving force. It is safe and convenient to use in complex places.
