DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] A threaded driving structure is employed to an automatic
umbrella with at least two stick sections.
[0017] For example, as shown in FIGS. 1 and 2, a threaded driving
structure for an automatic umbrella according to a first embodiment
of the present invention comprises: a first stick section 1, a
second stick section 2, and a third stick section 3, wherein the
second stick section 2 is fitted onto an outer wall of the first
stick section 1 and slides relative to the first stick section 1.
The first stick section 1 includes a first fixing sleeve 11
disposed on a top end thereof, and the first fixing sleeve 11 has a
first orifice 111 defined thereon. The second stick section 2
includes a second fixing sleeve 21 mounted on a top end thereof,
the first stick section 1 also includes a first support member 13
mounted therein, and the first support member 13 has inner threads
arranged therein, the second stick section 2 also includes a screw
rod 22 fixed therein, and the screw rod 22 has outer threads
arranged thereon (in this embodiment, the first support member 13
is cylindrical), wherein an upper end of the screw rod 22 is
connected with the second fixing sleeve 21, and a lower end of the
screw rod 22 is screwed with the inner threads of the first support
member 13 via the first orifice 111. A lower end of the first
support member 13 is joined with a power apparatus 4. In this
embodiment, the power apparatus drives the first support member 13
to rotate, and the screw rod 22 moves upwardly and downwardly along
the first support member 13. The third stick section 3 is fitted on
an outer wall of the second stick section 2 and slides relative to
the second stick section 2, wherein the third stick section 3
includes a third fixing sleeve 31 disposed on a top end thereof,
and the second fixing sleeve 21 has a second orifice 23 defined
thereon. In addition, the third stick section 3 also includes a
second support member 32 mounted therein, wherein an upper end of
the second support member 32 is in connection with the third fixing
sleeve 31, and a lower end of the second support member 32 is
inserted into the second orifice 23. The second stick section 1
further includes a first pull rope 24, an upper segment 241 of
which is coupled with the lower end of the second support member 32
through a support portion 25 on the second fixing sleeve 21. The
screw rod 22 also has an accommodation space 131 formed therein to
accommodate the second support member 32 and the first pull rope
24.
[0018] In assembly, a first runner 8 is fitted on the third stick
section 3, and a second runner 5 is fixed on an upper end of the
third stick section 3, wherein the second runner 5 has plural first
stretchers 51, plural second stretchers 52 secured among the plural
first stretchers 51 and the first runner 8, and plural springs 53
fitted among the plural second stretchers 52 and the plural first
stretchers 51. The power apparatus 4 is fixed in a handle 7 on a
lower end of the first stick section 1, In this embodiment, the
power apparatus 4 includes a battery 42 and a micro motor 41 driven
by the battery 42 (the power apparatus 4 can be manually operated
to provide power as well), wherein the battery 42 supplies power to
the micro motor 41 so that the micro motor 41 drives an output
shaft 411 on the first support member 13 to rotate. In this
embodiment, a button 6 is configured on the handle 7 and is pressed
to drive the micro motor 41 to rotate, such that the micro motor 41
drives the support member 13 to rotate clockwise, and the screw rod
22 moves upwardly along the first support member 13 (in this
embodiment, when the first support member 13 rotates
counterclockwise, the screw rod 22 moves downwardly along the first
support member 13), hence the second stick section 2 is driven by
the screw rod 22 to slide upwardly. Thereafter, the upper segment
241 of the first pull rope 24 in the second stick section 2 pulls
the second support member 32 upwardly to drive the third stick
section 3 to slide upwardly, such that the first stick section 1,
the second stick section 2, and the third stick section 3 stretch
completely, wherein the plural first stretchers 51 and the plural
second stretchers 52 are driven by the third stick section 3 to
stretch outwardly, and the plural springs 53 store energy so that
when the button 6 is released, the first support member 13 stops
rotation. As desiring to retract the automatic umbrella, the button
6 is pressed again so that the first support member 13 rotates
counterclockwise, and then the plural springs 53 drive a second
rope 33 to pull the first runner 8 downwardly, thereafter the first
pull rope 24 is pulled downwardly by the second support member 32,
and the first pull rope 24 and the second support member 43 move
into the first support member 13. When the first support member 13
rotates counterclockwise, the screw rod 22 moves downwardly along
the first support member 13, and the first pull rope 24 and the
second support member 32 move into the accommodation space 131 of
the screw rod 22, such that the automatic umbrella is retracted,
and the button 6 is released to stop a rotation of the screw rod
22. Accordingly, the power apparatus 4 supplies the power to rotate
the first support member 13, and then the screw rod 22 is driven by
the first support member 13 to move upwardly and downwardly along
the first support member 13, such that the plural springs 53 do not
produce excess elasticity, thus stretching the automatic umbrella
safely and prolonging a service life of the automatic umbrella.
[0019] Referring to FIGS. 3 and 4, a difference of an automatic
umbrella of a second embodiment from that of the first embodiment
comprises: the first stick section 1 including a first support
member 13 with outer threads, the second stick section 2 including
a screw rod 22 with inner threads, the first support member 13
having an accommodation space 131 for accommodating the second
support member 32 and the first rope 24.
[0020] While the preferred embodiments of the invention have been
set forth for the purpose of disclosure, modifications of the
disclosed embodiments of the invention as well as other embodiments
thereof may occur to those skilled in the art. Accordingly, the
appended claims are intended to cover all embodiments which do not
depart from the spirit and scope of the invention.
