DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0030] The technical solution of the present invention will be
further described by way of embodiments below in conjunction with
the accompanying FIGS. 1 to 7.
[0031] A seamless webbing loop of a rock climbing quickdraw is
disclosed. The webbing loop 1 of the quickdraw contains a plurality
of tubular webbing layers, one surrounded by another, among which
there is at least one indication layer 4. The indication layer 4 is
adjacent to the outermost one among the plurality of tubular
webbing layers or is the innermost one among the plurality of
tubular webbing layers. Such a multilayered structure of the
webbing loop enhances the strength of the webbing loop for the
quickdraw, but does not cause a seam to the webbing loop. Further,
the indication layer contained in the webbing loop functions to
remind a user of timely replacement of the webbing loop when the
webbing loop is worn, and thus the webbing loop is safe in use. In
addition, the webbing loop disclosed in the present invention has a
simple structure without any seam, and is strong, safe and
durable.
[0032] In an embodiment, the indication layer 4 is a solid webbing
having a rectangle or elliptic cross section, and is the innermost
layer among the plurality of webbing layers of the webbing loop. In
the case that a red elongated solid webbing having a rectangle
cross section is used as the indication layer 4, the red elongated
solid webbing is woven into the webbing loop as its innermost
layer. Accordingly, the webbing loop has a cross-sectional shape
that varies with the cross-sectional shape of the solid webbing. To
ensure the consistency of the cross-sectional shape of the webbing
loop with the cross-sectional shape of the solid webbing, the solid
webbing in the present embodiment is surrounded with three webbing
layers. However, the number of the webbing layers in the webbing
loop may be adjusted as desired in the production.
[0033] In an embodiment, the indication layer 4 is a hollow tubular
webbing section with a warning sign, and the hollow tubular webbing
section is adjacent to the outermost webbing layer among the
plurality of webbing layers of the webbing loop.
[0034] In another embodiment, the webbing loop may be woven in a
manner as shown in FIG. 3. After a section of hollow tubular
webbing is woven, a woven end 2 of the hollow tubular webbing is
placed into a weaving end (i.e. an end being woven) 3 of the hollow
tubular webbing, so that the webbing which is previously woven is
surrounded with a webbing which is subsequently woven during the
weaving process. The wire used for weaving the layer located below
the outermost webbing layer of the webbing loop may be in red or
any other color different from the color of the outermost webbing
layer, so that the layer located below the outermost webbing layer
forms the indication layer after being woven. It is easy for a user
to detect the wear of the outmost layer of the webbing loop as
disclosed in the invention and replace the webbing loop in time,
thus eliminating the security risks.
[0035] A textile machine for weaving the seamless webbing loop of a
rock climbing quickdraw is also disclosed herein, and the textile
machine includes a base 5, pads 6 arranged on the base 5, and a
spindle 7 arranged on each of the pads 6. The base 5 is provided
with an opening 8, where a movable spindle assembly fitting with
the opening 8 is arranged.
[0036] The spindle assembly includes a base unit, a pad 6 arranged
on the base unit and a spindle 7 arranged on the pad 6. The spindle
assembly may be fastened on the base by a screw. Alternatively, a
pivot is arranged at one side of the opening of the base, to
pivotally connect the spindle assembly to the pivot. Thus, the
spindle assembly may be conveniently detached to remove the woven
webbing loop, and attached to the base for the purpose of
weaving.
[0037] The textile machine is provided with a plurality of the
spindles 7, which are arranged in a circle. A webbing passage 9
running through the base is arranged at the center of the circle on
which the plurality of the spindles 7 are arranged. Some
transmission mechanism may be provided in the webbing passage to
move the woven hollow webbing during the weaving.
[0038] A gear shaft connecting with a plurality of gears is
arranged in the base unit. One end of the gear shaft is connected
with the spindle 7, and the other end of the gear shaft is
connected with a power unit of the textile machine, so that the
spindle 7 is driven by the power unit. The base unit is, for
example, hinged to a side of the opening 8, and may be snapped on
the other side of the opening 8. In another embodiment, the spindle
assembly is operated through the engagement between gears on the
gear shaft arranged on one side of the base unit and gears on a
motor shaft arranged on the rack of the textile machine. When it is
required to remove the woven webbing loop from the textile machine,
the base unit is unsnapped so that the spindle assembly may be
rotated aside to remove the woven webbing loop. However, the
invention is not limited thereto, and the base unit may be locked
and unlocked in any other manner.
[0039] A textile method for weaving a seamless webbing loop of a
rock climbing quickdraw using the above textile machine includes
the following steps of:
[0040] S1) starting the textile machine to weave a hollow webbing
having a length;
[0041] S2) guiding a woven end of the hollow webbing to the outside
of the textile machine and then inserting the woven end into a
weaving end of the hollow webbing via the webbing passage 9 at the
bottom of the base 5 of the textile machine to form a loop,
continuously weaving along the loop to sheathe the hollow webbing
with a plurality of webbing layers, and tying the weaving end to
the outermost webbing layer to form a woven webbing loop of the
rock climbing quickdraw, where an indication layer is adjacent to
the outermost webbing layer; and
[0042] S3) unsnapping the spindle assembly at an opening of the
base of the textile machine, and removing the woven webbing
loop.
[0043] A textile method for weaving a seamless webbing loop of a
rock climbing quickdraw using the above textile machine includes
the following steps of:
[0044] S1) starting the textile machine to weave a tubular webbing
having a length, which sheathes a solid webbing;
[0045] S2) guiding a woven end of the tubular webbing sheathing the
solid webbing to the outside of the textile machine and then
inserting the woven end into a weaving end of the tubular webbing
via the webbing passage 9 at the bottom of the base 5 of the
textile machine to form a loop, continuously weaving along the loop
to sheathe the tubular webbing with a plurality of webbing layers,
and tying a weaving end to the outermost webbing layer to form a
woven webbing loop of the rock climbing quickdraw; and
[0046] S3) unsnapping the spindle assembly at an opening of the
base of the textile machine, and removing the woven webbing
loop.
[0047] In a variant of the present embodiment, a webbing section
with a distinguishing color may be woven in the weaving of the
textile machine, and woven into the webbing loop to form the
indication layer adjacent to the outermost webbing layer of the
webbing loop, so that a user may be reminded of the wear of the
webbing loop and the replacement of the webbing loop in time.
Furthermore, the solid webbing may have a different shape as
desired, to form the webbing loop having cores-sectional shape as
required.
[0048] The technical principles of the present invention have been
described in conjunction with the embodiments as above. The
description is only intended to explain the principles of the
present invention, but not to limit the invention. Based on the
explanation herein, other embodiments can be conceived by those
skilled in the art without any creative work, thus these
embodiments should be included within the protection scope of the
invention.
