CONSTRICTIVE BAND
Abstract
A constrictive band includes a band body and a positioning
member. The band body has a free end inserted through an insert
hole of the positioning member and fixed at any location of the
band body relative to said positioning member by means of a band
fixing unit of the positioning member, forming a circle to
constrict and hold something therein tightly and immovably. The
band body can be easily handled to be inserted through the inert
hole, and pulled out of the insert hole simply by compressing plate
members of the positioning member for loosening the band body,
permitting the constrictive band usable repeatedly for a long
time.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a constrictive band, particularly
to one easy to handle and possible to be used repeatedly.
[0003] 2. Description of the Prior Art
[0004] Conventional constrictive bands are widely used in our daily
life for constricting things stably, often used for positioning
tubes or binding linear matters to be stored.
[0005] A Taiwan patent of No. 285970 disclosed "Constrictive Band",
another Taiwan patent disclosed "Constrictive Band used in a
Constrictive Gun", and another Taiwan patent disclosed "Stationary
Line constrictive band". However, those three articles are not so
ideally structured, needing improvement for its handling and usable
durability.
SUMMARY OF THE INVENTION
[0006] This invention has been devised to offer a constrictive band
easily handled for constricting something in a circle formed by the
constrictive band and possible to be used repeatedly for a long
time.
[0007] The features of the invention are a band body and a
positioning member detachably combined together. The band body is
elongate and flat, provided with ratchet teeth on one or two
longitudinal sides. The positioning member is an empty block and
combined integral with one end of the band body, having a center
insert hole for the band body to insert though and a band fixing
unit respectively formed on an inner wall of two longitudinal
sides. The band fixing unit is composed of two plate members, two
elastic strips extending along two inner sides of the insert hole,
a ring pushing and keeping the elastic strips positioned in place,
an anti-retreat claw formed on an inner surface of the elastic
strips to engage with the ratchet teeth for fixing the band body
stably and immovable at one of many locations relative to the
positioning member for forming a circle of various sizes to
constrict something tightly therein.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] A constrictive band 1 in the present invention, as shown in
FIG. 1, includes a band body 11 and a positioning member 12 as main
components.
[0019] The band body 11 is a long flat strip, having a plurality of
ratchet teeth 111 formed on one or two longitudinal sides, and a
free end with a guide (tapered) angle 112 for easy inserting.
[0020] The positioning member 12 is an empty mass, having a through
insert hole 120 in its center and a band fixing unit 121
respectively formed in an inner wall of the two longitudinal sides,
and a reinforcing rib 124 formed on the surface of the longitudinal
side for strengthening a combining point where the end of the band
body 11 is combined integral with the positioning member.
[0021] Next, as shown in FIGS. 3A, 3B, 3C, 4A, 4B, and 5, in using,
the band body 12 is inserted through the through insert hole 120 of
the positioning member 12 and then kept tight and immovable at a
needed length by means of the two fixing units 121 so that the band
body 11 may form a circle in order to constrict something in the
circle tightly and immovable.
[0022] Each fixing unit 121 is composed of a plate member 1211, an
elastic strip 1213, a ring 1214, and an anti-retreat stopper 1215.
Further, a groove 1212 is formed at two sides of the insert hole
120 in the plate member 1212, located lengthwise and parallel to
each other. The elastic strip 1213 is elongate and located to
extend along the insert hole 120 from the bottom of an inner wall
of the plate member 1211 out of the insert hole of the positioning
member 12. The ring 1214 is located in the insert hole 120, of the
positioning member 12, pushing and keeping the elastic strips 1213
in place. The anti-retreat claw 1215 projects inward from the inner
surface of each elastic strip 1213, engaging with the ratchet teeth
111 of the band body 11 after the band body 11 is inserted through
the insert hole 120 so that the band body 11 can only move in, but
cannot retreat by means of function of the anti-retreat claw 1215.
Thus the band body 11 is impossible to loosen off the positioning
member 12 after inserted and positioned therein.
[0023] Furthermore, an auxiliary horizontal positioning block 122
can be added at an upper side and a lower side in the insert hole
120, and a vertical positioning block 123 can be added at the right
and the left side in the insert hole 120 to limit the band body 11
to move in the special space surrounded by the two horizontal
blocks 122 and the two vertical blocks 123 in the insert hole 120
of the positioning member 12, so that the band body 11 may not
loosen, bias or wrongly be positioned in the insert hole 120.
[0024] Next, FIG. 6 shows the band body 11 is loosened in the
positioning member 12, with the plate members 1211 pressed inward
to force the ring 1214 to bend down, so that the elastic strip 1213
may curve down, Therefore, the ant-retreat claw 111 disengages from
the ratchet teeth 111, permitting the band body 11 to retreat out
of the insert hole 120, freeing the band body 11.
[0025] When the band body 11 in a constricted condition is to be
loosened from the positioning member 12, as shown in FIGS. 7 and 8,
the two plate members 1211 are compressed inward, and then the ring
1214 is bent inward so that the elastic strips 1213 may be pushed
outward to force the claws 1215 to disengage from the ratchet teeth
111. Therefore, the band body 11 can be pulled completely out of
the positioned member 12 via the insert hole 120, freeing the band
by 11.
[0026] In addition, a plurality of the constrictive bands 1 can be
connected together as shown in FIG. 9, by means of the band body 11
of a first constrictive band 1 inserted in the positioning member
12 of a second constrictive band 1, the band body 11 of the second
constrictive band 1 inserted in the positioning member 12 of a
third constrictive band 1, and the band body 1 of the third
constrictive band 1 inserted in the positioning member 12 of the
first constrictive band 1. Thus a circle formed by the three band
bodies 11 can receive something therein for constricting it tightly
and immovable.
[0027] This invention has the following advantages, as can be seen
from the foresaid description.
[0028] 1. Easy constriction and loosening of the band body: as the
band body has the ratchet teeth and the positioning member has the
band fixing units, the band body is easily inserted through the
insert hole and kept stably and immovable by engagement of the
ratchet teeth with the band fixing units at one of many locations;
when the constricted band body is to be loosened off, only
compressing the plate members can disengage the claws of the band
fixing units from the ratchet teeth to permit the band body to be
pulled and freed out of the positioning member, very convenient to
use.
[0029] 2. Repeatable use: This constrictive band can be used many
times for a long time, by the band body possible to be assembled
with and disassembled from the positioning members.
[0030] While the invention has 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.
