Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an actuating device, and more particularly, to an automatic operation providing a two-step opening operation or opening procedure so that the stopper of an automatic umbrella is accidentally pulled and the automatic umbrella is not opened unexpectedly. Actuator for an umbrella.

BACKGROUND OF THE INVENTION Umbrellas are very important for everyday life, especially for people who live in rural areas of the wet season or wet climate. The conventional umbrella has a relatively simple structure, and when the user tries to open the umbrella, the umbrella has to be pushed to open the umbrella. This way of pushing and opening is inconvenient, which is why the automatic umbrella was invented. The automatic umbrella has an actuating device and an elastic member, a user can press a button of the actuating device, and the automatic umbrella automatically opens by a force given by the elastic member.

Automatic umbrellas have many advantages, such as convenience and quick opening, which are especially important for downhill skies. However, the automatic umbrella has a disadvantage that, for example, the button of the actuating device is accidentally pressed and the automatic umbrella is opened abruptly. This unfavorable opening of the umbrella is serious when it hits a person and is injured, and hits a sensitive portion such as an eye. Also, the abrupt opening of the automatic umbrella hits an object and damages both the object and the automatic umbrella.

The two balance springs 36A and 36B are formed to have hook portions 362A and 362B. The balance springs 36A and 36B have corresponding holes 329 and 3 in the upper piece 32 and the lower piece 34, respectively.
The hook 49 can be hooked through the hook portions 362A and 362B. The balance springs 36A and 36B are provided to impart elasticity or elasticity to the upper piece 32 and the lower piece 34.

The upper button 38 has a ring-like shape and includes a crown portion 382 and a ring 384 integrally formed with each other. The ring 384 has such a shape that it can be placed around the hollow handle 10 of the automatic umbrella.

The lower button 39 has the same shape as the upper button 38, and the crown portion 39 formed integrally with each other.
2 and a ring 394. Since the ring 394 is formed in this way, it can be installed around the hollow handle 10 of the automatic umbrella.

Both the upper slot 102 and the lower slot 104 are provided near the bottom end of the hollow handle 10. The upper slot 102 may have adjacent ends 322, 342 of the upper piece 32 and the lower piece 34 partially protruding outside the upper slot 102. The lower slot 104 is provided closer to the bottom end of the handle 10 than the upper slot 102.
Located on the opposite side of. Two holes 103A and 103B are provided between the upper slot 102 and the lower slot 104 and extend across the handle 10. Two holes 103A,
103B are arranged close to each other along the longitudinal axis of the handle 10.

The handle 20 installed around the bottom end of the handle 10 has an upper receiving hole 202 and a lower receiving hole 2
04 and. Both receiving holes 202, 204 are arranged close to each other and along the longitudinal axis of the handle 20. Both receiving holes 202, 204 are shaped to receive the upper button 38 and the lower button 39, respectively.

In assembling the operating device, the hook portions 362A and 362B of the balance springs 36A and 36B are fitted in the holes 32 of the upper piece 32 and the lower piece 34, respectively.
9, 349, the balance spring 36
A and 36B are hooked on the corresponding upper piece 32 and lower piece 34, respectively. Next, the upper piece 32 and the lower piece 34 are placed inside the hollow handle 10 between the upper slot 102 and the lower slot 104. The upper shaft 35A includes the hole 103A of the handle 10 and the lower piece 34.
Of the shaft piece 345 and the opening 328 of the upper piece 32 in that order. The lower shaft 35B is the shaft hole 103B of the handle 10.
And extends through the opening 348 of the lower piece 34 and the shaft hole 325 of the upper piece 32 in order. Therefore, the upper piece 32 and the lower piece 34 are pivotally attached inside the hollow handle 10, and the adjacent end 322 of the upper piece 32 and the adjacent end 342 of the lower piece 34 are connected to the upper slot 1 of the handle 10.
02, and the pressing end 324 of the upper piece 32 and the pressing end 344 of the lower piece 34 have a handle 1
It partially projects from the 0 lower slot 104. The notches 326 and 346 are provided for the balance spring 3 to avoid interference when the upper piece 32 or the lower piece 34 pivots.
It straddles the hook portions 362A and 362B of 6A and 36B. Part of the hairsprings 36A, 36B facing each other with respect to the hook portions 362A, 362B are
It abuts the inner surface of the hollow handle 10 to provide an elastic restoring force to the upper piece 32 and the lower piece 34 during pivoting of the two pieces 32, 34. The upper button 38 and the lower button 39 respectively correspond to the upper receiving hole 20 of the handle 20.
2 and the lower receiving hole 204. The handle 20 is further mounted around the bottom end of the handle 10 with the rings 384, 394 of the upper and lower buttons 38, 39 and the inner surfaces of the crowns 382, 392 respectively of the upper piece 32 and the lower piece 34. Mounted around the bottom end of the handle 10 to engage the corresponding push ends 324, 344.

Referring to FIG. 3, when the automatic umbrella is in the folded state, the adjacent end 342 of the lower piece 34 is
It partially protrudes outside the upper slot 102 defined in the hollow handle 10. A restriction piece 106 formed at one end of the hollow shaft 15 is adjacent to an adjacent end 342 of the lower piece, which limits the automatic umbrella to the folded state shown. Further, referring to FIG. 4, when the user presses the lower button 39, the lower button 39
Crown 392 pushes against the push end 344 of the lower piece 34 and pivots the lower piece 34 such that the adjacent end 342 enters into the upper slot 102. As a result, the limiting piece 106 is no longer in close proximity to the adjacent end 342 of the lower piece 34, and the at least one elastic member provides elasticity and pushes the automatic umbrella toward the opening direction. The restriction piece 106 then approaches the adjacent end 324 of the upper piece 32 and the automatic umbrella is left unopened as shown. Referring to FIGS. 5 and 6, the automatic umbrella does not fully open until the user presses the upper button 38.
When the user presses the upper button 38, the crown 382 of the upper button 38 presses the push end 324 of the upper piece 32, causing the upper piece 32 to pivot. Similarly, the adjacent end 322 of the upper piece 32 enters into the upper slot 102 and releases the restriction piece 106. The elastic force applied by the at least one elastic member pushes the automatic umbrella to a completely opened state.

From the above, it will be appreciated that the actuating device 30 for the automatic umbrella according to the invention has the advantage of providing a safety function. That is, when the user tries to open the folded automatic umbrella, the user
The lower button 39 and the upper button 38 must be pressed successively. This two-step opening operation or opening procedure can avoid possible injuries and accidental uprighting of the automatic umbrella in order to protect it.

However, while numerous features and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative.
Changes are made in detail, particularly in matters of shape, size and arrangement of parts within the principles of the invention, to the full extent indicated by the broad general meaning of the words recited in the claims. It will be understood.
