STRIDING SHANK FIXING DEVICE
Abstract
A striding shank fixing device includes an insert tube, a guide
tube, and an adjusting member. The guide tube has plural position
holes, and the adjusting member has a hole for the guide tube to
pass through and a position projection to fit in one of the
position holes to secure the adjusting member with the guide tube
at an adjusted location. A thumb screw screws through the adjusting
member to press a driving strip to push forcefully against a
vertical side of a wall to secure the shank fixing device striding
on the wall so the shank of a parasol may be inserted in the insert
tube and stabilized by a thumb screw screwing through the insert
tube and pressing against a driving block in the insert tube and
pressing against the shank to support the parasol stably.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a striding shank fixing device,
particularly to one possible to stride and fix on a vertical wall
and adjustable its position according to the thickness of the wall
where the device is secured on.
[0003] 2. Description of the Prior Art
[0004] A shank-fixing device is used for a flagpole or a shank of a
parasol, generally to stand on the ground and expanded thereon,
having an insert tube in the upper side for a shank or pole to be
inserted from above downward and then fixed at a proper height.
This kind of fixing device in the spread condition sits on the
ground, taking rather a large area, and resulting in wasting the
space. Further, passersby may carelessly collide with it and force
it to fall down, and it is possible to accidentally hurt
someone.
SUMMARY OF THE INVENTION
[0005] This invention has been devised to offer a striding shank
fixing device so as to improve the conventional shank-fixing frame
sitting on the ground for supporting a flagpole or a parasol.
[0006] The feature of the invention is a guide tube fixed outside
of a insert tube and having plural position holes, and an adjusting
member having a hole for the guide tube to pass through and a
position projection to fit in any of the position holes of the
guide tube to secure the adjusting member at one of many adjustable
locations relative to the guide tube. Further, a thumb screw screws
through the adjusting member to press a driving strip to move
synchronously against a vertical surface of a wall. The insert tube
is located at the other vertical surface of the wall and a
thumbscrew screws into the insert tube to press a driving block in
the insert tube to push against the shank of a parasol inserted in
the insert tube keep the shank immovable. Then the striding shank
fixing device may be secured stably and striding on the wall of any
thickness by adjusting the position of the adjustable member
relative to the guide tube.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] A first embodiment of a striding shank fixing device in the
present invention, as shown in FIGS. 1 and 2, includes an insert
tube 10, a guide tube 20, and an adjusting member 30 as main
components combined together.
[0015] The insert tube 10 is straight, having its hollow interior
for a shank 1 (like a flagpole or a shank of a parasol) to fit
therein, a female-threaded hole 11 formed in a side for a thumb
screw 12 to screw in the insert tube 10 so as to forcefully move
inward a driving block 13 located in the insert tube 10 to press on
the outer surface of the shank 1. Further, a fix plate 14 is
attached firmly with the outer surface of the insert tube 10.
[0016] The guide tube 20 has its inner end fixed firmly with the
fix plate 14, and the other end extending outward, provided with a
plurality of position holes 21 spaced apart equidistantly in a
lower side.
[0017] The adjusting member 30 has a hole 31 in an upper portion
for the guide tube 20 to pass through, a projection 32 on an inner
wall of the hole 31 to correspond to any of the position holes 21
of the guide tube 20, a female-threaded hole 33 formed in a lower
portion for a thumb screw 34 to screw therein. The thumbscrew 34
has its end pressing against the fix plate 14, and a driving strip
35 is provided between the insert tube 10 and the fix plate 14.
[0018] After the striding shank fixing device is assembled together
as shown in FIGS. 2 and 3, the guide tube 20 is inserted through
the hole 31, and the angle of the adjusting member 30 is adjusted
properly and then fixed on a vertical wall surface 2 by pulling the
adjusting member 30 nearer to the vertical wall surface 2, and
straightening the adjusting member 30 to force the projection 32
engage in one of the position holes 21 of the guide tube 20. Then
screw inward the thumbscrew 34 and move the driving strip 35 to
push tightly against the wall surface 2. Then the striding shank
fixing device is secured striding on the wall surface 2. As shown
in FIGS. 3 and 4, after the shank 1 is inserted in the insert tube
10, the thumb screw 1 2 is rotated inward to forcefully move the
driving block 13 to push tightly against the shank 1 to the insert
tube 10, securing the shank 1 stably therein. As the adjusting
member 30 can be adjusted its location on the guide tube 20, it can
be temporarily positioned securely at the adjusted point by making
the projection 32 engage one of the position holes 21. So the
shank-fixing device can be adjusted according to the thickness of
the wall where it is to be secured, possible to stride on a wall
and secured on a vertical surface of a wall with any thickness.
[0019] Next, FIGS. 5 and 6 show a second embodiment of a striding
shank fixing device in the invention, which has almost the same
structure as the first embodiment, except that the insert tube 10
has lengthwise opening 15 for a shank 1 of a parasol to pass
through into the interior of the insert tube 10, without need to
insert it from above into the insert tube 10, more convenient to
handle and without any unstableness in inserting process.
[0020] While the preferred embodiments of the invention have been
described above, it will be recognized and understood that various
modifications may be made therein and the appended claims are
intended to cover all such modifications that may fall within the
spirit and scope of the invention.
