ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an anchoring apparatus for multi-section pulling bar of trunks and particularly an anchoring apparatus that allows the pulling bar latched securely at selected locations when the multi-section pulling bar is collapsed and retracted.
2. Description of the Prior Art
A commonly used multi-section pulling bar
10
for trunks (as shown in
FIG. 1
) mainly includes a handle
11
with two ends thereof engaging respectively with an inner tube
12
. The inner tube
12
has a linkage bar
121
run through therein to fasten to an anchoring means
15
. The inner tube
12
is housed in a middle tube
13
which in turn is housed in an outer tube
14
. The middle tube
13
has a plurality of latching bores
131
formed on the tubular wall and another anchoring means
15
located at the bottom of the middle tube
13
. The anchoring means
15
has an inner clip tube
151
which has a control element
152
located therein. The control element
152
has one end connecting the linkage bar
121
and another end
153
engaging with a clip tongue
153
. The clip tongue
153
has a rear end coupled with a spring
154
. The clip tongue
153
is driven by the linkage bar
121
to couple with the latching bores for mooring the tubes thereby to provide the pulling bar collapsible function. However the structure set forth above still has drawbacks when in use, notably:
When the handle
11
is not being grasped and depressed, the inner tube
12
tends to stop in the middle tube
13
, and the middle tube tends to stop in the outer tube
14
, while the anchoring means
15
of the inner tube
12
is engaged with the latching bore
131
, the clip tongue
153
of the another anchoring means
15
of the middle tube
13
is not extended. Hence the middle tube
13
and outer tube
14
do not engage securely and positively. When the pulling bar is retracted, the middle tube
14
and outer tube
15
tend to wobble. There are still rooms for improvement.
SUMMARY OF THE INVENTION
In view of aforesaid disadvantages, it is a primary object of the invention to provide an anchoring apparatus that allows multi-section pulling bar of a trunk to engage and position firmly and securely.
The anchoring apparatus of the invention mainly includes an anchoring bore at the bottom section of the outer tube to match a jutting stub of a lower anchoring means and an anchor bolt of a lower extensible button such that when the pulling bar is extended, the jutting stub of the lower anchoring means will be extended to engage with an latch bore of the outer tube, and when the pulling bar is retracted the anchoring bolt will be extended to engage with the anchoring bore of the outer tube.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
