Description

Improved safe control structure of automatic opening and closing umbrella {SAFE CONTROL STRUCTURE FOR AUTOMATIC UMBRELLA}

The present invention relates to a technology for improving the control structure of an automatic open / close umbrella among the types of umbrellas. In case of a mistake in the compression operation of folding an umbrella by using a combination of precise, simple and recoil prevention wheels and a locking control body, The intermediate rod equipped with the umbrella is not subjected to the instantaneous bounce of the compressed umbrella opening spring, and due to this structure, the safety of the use and control of the automatic opening and closing umbrella can be greatly improved.

The control structure and operation method of a generally used automatic opening and closing umbrella is disclosed in US Pat. No. 6,684,893B2. The control structure is installed inside an umbrella handle, and a control annular body is installed inside a main body having an air core inside. The control column is installed at the bottom of one side of the control annular body, and a button is installed at one side of the main body to be exposed outward from the opening of the side of the umbrella handle. The combination of such a configuration enables the guard of the umbrella middle rod. However, the biggest problem of the automatic opening and closing umbrella occurs during the compression process to fold the umbrella, when the spring inside the middle bar provided with the umbrella proceeds to the compression operation when the umbrella folded, the strength and elasticity of the spring of the open umbrella This is not all small. Therefore, the user must use the hand to compress the umbrella with very high force and insert it into the retainer. However, if the force or motion is not appropriate, the pressure of the spring of the open umbrella is a large force to bounce the middle rod to injure the user's hand or other parts of the body routinely. This is a problem associated with the use of the automatic opening and closing umbrella.

In addition, the control structure design of the automatic open and close umbrella with safety is disclosed in "Automatic umbrella which can be folded safely" of Chinese Patent Application No. CN101653309A. The structure disclosed in the above rights to avoid the risk of repeated elasticity in the middle bar even when folding the umbrella by diarrhea compression. However, when the technical contents are carefully examined, the end of the rope on the ratchet and the end of the extension rope on the lower groove are fixed to the button head at the same time, indicating that the ratchet and the lower groove interlock with each other, and thus are installed on the lower groove. In the case of folding, the end of the rope on the ratchet is not fixed to the groove, which prevents the middle rod from being bounced back, but also promotes the lower groove to fully open the umbrella, so this structure can achieve the effect of the safety folding umbrella. There is no way, and it is not very ideal and still needs improvement.

This creation provides an improved safe control structure of the automatic open / close umbrella. The improved structure after further research which solves the above-mentioned creative defect is disclosed in FIGS.

The control structure is installed inside the umbrella handle (1), and is firmly connected to the first section intermediate bar 31 of the intermediate rod line (3), mainly the main body 20, the operation cover 21, the locking control body And a support tube 35 having a slot groove 351 installed at one side of the lower end of the first rod intermediate rod 31 of the intermediate rod line 3. It is firmly coupled to the inside of the main body 20, the slot groove 311 is also installed on one side of the lower end of the first middle bar 31. In addition, the side grooves adjacent to each other has a long groove 312 is formed in the end portion, the spring 24 is mounted on the bottom of the operation cover 21 to cover the first intermediate bar (31). One side of the main body 20 is provided with a device accommodating groove 201 having an opening 202 is mounted to the locking control body 22. At the top of the locking control body 22, a thin shaft 26 is installed to rotate inside the device accommodation groove 201, and an operating bag 221 is formed at one side to pass through the opening 202. And on the back is the elastic piece 25 is installed in combination. The rebound preventing wheel 23 is installed in the lower half of the main body 20, the ratchet 231 having a plurality of the same inclination is formed below the locking control body 22 and formed on the side, the spring 27 on the other side Formulation is installed. In addition, it is installed so as to be wound on the reaction prevention wheel 23, one end is firmly coupled on the reaction prevention wheel 23, the other end is a gap 313 along the long groove 312 of the first section intermediate bar (31) Passing through there is a safety strap 28 is inserted into the space in the middle rod line 3 is firmly fixed to the upper coupling house 41 toward the upper side.

This combination structure makes it possible to measure the position of the middle rod line during compression by using the locking action of the locking control body and the recoil prevention wheel and the locking of the safety strap even if the mistake is made in compressing the middle rod when folding the umbrella. Therefore, the safety of the automatic opening / closing umbrella is ensured by preventing the spring of the open umbrella from acting while the intermediate rod line is being compressed.

1 is an exploded view of the safe control structure of the present invention.
2 and 3 is an exploded view after folding the umbrella of the present invention compressed.
4 and 5 are exploded views when the umbrella of the present invention is opened.
6 and 7 is an exploded view of folding the umbrella meat in the present invention compressed.

2 and 3, an embodiment of the inventive three-stage folding umbrella is shown. The basic member includes an umbrella handle (1), the middle rod line (3), the active combination collection (4), the elastic head (5), the umbrella opening spring (6) and the umbrella meat (7). On the umbrella handle 1, a button 10 provided with a control ring 11 and a controller column 12 is installed, and the intermediate rod line 3 is formed of a first rod intermediate rod 31 and a second intermediate rod. Rod 32, and the third section intermediate bar 33 is formed by combining one. The upper coupling house 41 is firmly coupled to the top of the third section bar 33, and the locking hole 331 is installed at one side of the lower end. An inner tube 34 is firmly coupled to the lower end of the upper coupling house 41, and the umbrella opening spring 6 is installed between the first section middle rod 31 and the inner tube 34. The elastic head 5 is installed below the inner tube 34, the tow string 51 is firmly connected to the bottom. In addition, the tow strap 51 passes upward through the inner tube 34, wraps the pulley in the upper coupling house 41, and again winds up behind the pulley in the active coupling house 4 toward the outside. The tip is firmly connected on the upper coupling (41). In addition, the safe control structure (2) of the present invention is installed in the umbrella handle (1), and is firmly coupled to the lower end of the first section intermediate bar (31).

Referring again to the contents shown in FIGS. 2 and 3, the automatic opening and closing umbrella of the present invention is compressed to fold an umbrella, and then the engaging hole 331 and the protruding portion of the control ring 11 on the middle section 33 of the third section. 111 forms a clip engagement to control and position the intermediate rod line (3). At the same time, the controller column 12 is pushed toward the bottom of the middle section 33 to form an inclined shape. In addition, the resilient head (5) connected to the tow string 51 and the active coupling (4) is moved downward along the inner tube (34) so that the end of the push rod 211 of the operation cover 21 and the operation cover ( 21) is pushed downwards. In addition, the first section is supported and pushed by the elastic piece 36 of the support pipe 35 in the middle bar 31 and is clipped on the slot groove 351. The lower portion of the lower movable cover 21 pushes the operator's bag 221, which is pushed by the locking control body 22 and engaged with the ratchet 231 of the lower end of the locking control body 22 and the recoil preventing wheel 23. Depart from the thing. At this time, the spring 27 in the reaction prevention wheel 23 is completely loose, and the safety strap 28 is wound on the reaction prevention wheel 23.

4 and 5, when the umbrella 10 is to be opened directly when the button 10 is pressed, the control ring 11 is pushed, and the protrusion 111 is caught in the middle section 33 of the rod 3. 331 is out of the clip engagement. In addition, under the action of the umbrella opening spring (6) in the middle bar line (3), the middle bar line (3) is fully unfolded, supporting the active combination house (4) moved upwards to unfold the umbrella flesh (7). When the automatic opening operation of the umbrella is completed, the control column 12 at this time also returns to the horizontal form and supports the slot groove 311 of the first rod intermediate bar 31. In addition, the end of the safety strap 28 is connected to the upper coupling member 41 extends upward along the upper coupling member 41 to move the anti-rebound wheel 23 to turn counterclockwise. As a result, the spring 27 on the recoil prevention wheel 23 is rolled up to form a contracted shape.

6 and 7, when the user wants to fold the umbrella, the button 10 is pressed again. At this time, the control column 12 pushes the elastic head 5 to be out of the clip coupling of the slot groove 351 of the support pipe 35, and of the umbrella folding spring 71 on each umbrella (7) Under operation, each umbrella (7) is automatically folded to allow the activity combination house (4) to move down. In addition, the tow strap 51 pulls the elastic head 5 upwards to reach the bottom of the inner tube 34. At this time, the operation cover 21 is not pressed by the end of the elastic head 5 so that the spring ( 24) moves upward to its original position. This eliminates the push of the lower part of the locking control body 22, and causes the locking control body 22 to be pushed back in the original direction by the elastic piece 25 on the rear surface of the locking control body 22. Therefore, the lower end thereof is rotated so as to be opposed to the ratchet 231 on the recoil prevention wheel 23 to be engaged.

The final action of folding the umbrella is to compress the middle rod line 3 of the umbrella. When the middle rod line 3 is compressed by an external force, the safety strap 28 is contracted and relaxed along the inside of the middle rod line 3. At this time, the recoil prevention wheel 23 is operated clockwise under the action of the restoring force of the spring 27, the ratchet 231 of the recoil prevention wheel 23 is inclined form the rebound prevention wheel 23 is clockwise In operation, the ratchet 231 allows the locking control body 22 to rotate without being clipped. However, when removing the compressive force, the elasticity of the umbrella opening spring (6) in the middle rod line (3) should push the middle rod line (3) to expand, but one end of the safety strap 28 on the recoil prevention wheel (23) is the upper coupling Since the tension is applied to the safety strap 28 by being coupled to the house 41, the recoil prevention wheel 23 should be rotated counterclockwise, but at this time, the latching control body 22 has a ratchet of the recoil preventing wheel 23. Clipping on 231 prevents the recoil prevention wheel 23 from rotating in the counterclockwise direction. Therefore, the middle rod 33 directly pulls the middle rod line 3 so that the middle rod line 3 stops momentarily and cannot be unfolded by elasticity.

Thus, if the mistake in the compression operation for folding the umbrella, the rebound prevention wheel 23 is under the clip control of the locking control body 22, pull the middle bar line (3) to stop and fix the position of the middle bar line ( 3) This prevents the phenomenon of instantaneous bounce by the umbrella opening spring 6 under compression, and achieves absolute safety of the use of the automatic opening and closing umbrella.
