first embodiment

[0046]Referring to FIGS. 1, 2a, 2b and 2c, the handle assembly of a self-opening umbrella of the present invention comprises a handle 15 which is a hollow handle and a frame 11 is received in the handle 15. A switch 12 is connected to the frame 11 and can be accessed via an opening defined in the handle 15. The handle 15 has two grooves 19 defined therein and a cap 18 is slidably engaged with the grooves 19 so that the cap 18 is slidably connected to the handle 15 and movably between a first position and a second position. The first position of the cap 18 is located to cover the cap 18 and the second position of the cap 18 is located to uncover the switch 12. Two decoration boards 16, 17 are connected to two sides of the handle 15.

[0047]A positioning device is connected between the cap 18 and the handle 15 so as to position the cap 18 at one of the first position and the second position. The positioning device includes a recess 151 defined in the handle 15. A spring 14 and a bead 13...

second embodiment

[0048]FIGS. 3 and 4a to 4c show the handle assembly for umbrella of the present invention, wherein handle 23 is a hollow handle and the frame 21 is received in the handle 23. The switch 22 is connected to the frame 21 and can be accessed via an opening defined in the handle 23. Two decoration boards 24, are connected on two sides of the handle 23. A close part 27 is connected to the handle 23 and a space is defined between the close part 27 and the handle 23. The cap 26 is received in the space when the cap is located in the second position. A stop 28 extends perpendicularly from the handle 23 so as to stop the cap 26 and prevents the cap 26 from being disengaged from the handle 23. A ridge 261 extends from an end of the cap 26 and is higher than an outer surface of the close part 27 and the user can push the ridge 261 to operate the cap 26. The positioning device 29 includes a spring and a bead so as to position the cap 26.

third embodiment

[0049]FIGS. 5 and 6a to 6c show the handle assembly for umbrella of the present invention, wherein the cap 32 has a plurality of blocks 321 extending from two sides of an underside thereof and the blocks 321 are movably engaged with the grooves 34 in the handle 3 so as to cover or uncover the switch 31. The positioning device includes two torsion springs 33 and each torsion spring 33 has a first leg and a second leg. Two respective first legs are connected to a protrusion 331 on the handle 30 and two respectively second legs are connected to two holes 322 in the underside of the cap 32.

Abstract

A handle assembly for umbrellas includes a switch connected to the frame which is received in the handle and the switch is accessed via an opening defined in the handle. An operation member is rotatably mounted to the handle and positioned a first position and a second position. The first position of the operation member is located to cover the switch and the second position of the operation member is located to uncover the switch. The operation member can be replaced by a cap which is pivotably or rotatably connected to the handle to cover or uncover the switch.

Description

FIELD OF THE INVENTION[0001]This is a safety device which includes a cap or an operation member movably or rotatably connected to the handle of an umbrella so as to avoid the switch of the umbrella from being touched unintentionally.BACKGROUND OF THE INVENTION[0002]A conventional umbrella 10 is shown in FIG. 21 and generally includes a shaft 8 with a runner 7 movably mounted to the shaft 8, a cap unit 6 connected to a top end of the shaft 8, and a frame and a handle 10 which is connected to a lower end of the shaft 8. The frame 9 includes a plurality of stretchers pivotably connected between the runner 7 and ribs which can be folded to collapse the frame 9. Most of the umbrellas are self-opening umbrellas which have a switch 12 and allow the user to touch the switch to open the umbrella or collapse the umbrella. However, the switch 12 does not have any safety device so that it might be touched unintentionally.[0003]The present invention intends to provide a safety device which restr...
