TWISTING ROLLER WITH A LOCKING AND CUTTING MECHANISM FOR WIRE
ENDS
Abstract
The present invention provides an improved twisting roller with
a wire ends locking and cutting mechanism. The twisting roller
includes a spool, a baffle plate at both ends, and a housing
externally on the twisting roller. The locking groove and cutting
groove are assembled onto the baffle plate of the twisting roller
or hanging piece of the housing. A cutter is assembled into the
cutting groove. The wires can be pulled through the locking groove
and cutting groove for direct cutting. After the wires are cut, the
wire ends are locked securely into the locking groove, and a
portion is exposed for convenient operation and fixation with
improved applicability.

CROSS-REFERENCE TO RELATED U.S. APPLICATIONS
[0001] Not applicable.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] Not applicable.
NAMES OF PARTIES TO A JOINT RESEARCH AGREEMENT
[0003] Not applicable.
REFERENCE TO AN APPENDIX SUBMITTED ON COMPACT DISC
[0004] Not applicable.
BACKGROUND OF THE INVENTION
[0005] 1. Field of the Invention
[0006] The present invention relates generally to a twisting
roller, and more particularly to an innovative roller which allows
a locking groove and cutting groove to be assembled onto the baffle
plate or housing for cutting and fixing wires.
[0007] 2. Description of Related Art Including Information
Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
[0008] The twisting roller of the present invention is an auxiliary
tool that is widely applied to the construction and decoration
industry. It generally has a circular shaft with expanded plate at
both ends, where a ring groove for reeling of wires is defined
externally onto the circular shaft. When the existing twisting
roller is employed, the operators shall pull out the wires to a
predefined length, then cut the wires with tools, pliers or burn
out the wires with a cigarette lighter. However, when the twisting
roller is applied to a flat location for horizontal or vertical
measurement, the operators are often positioned on the scaffold or
at dangerous site, and have to manually grasp the wires on the
twisting roller while using pliers or lighters. In such case, there
is the danger that operators may lose their balance. From another
viewpoint, given the fact that the wires on twisting roller are
made of flexible materials, the workers may find it difficult to
cut off the wires with commonly used pliers. Also, the flame of the
lighters may possibly be extinguished due to strong winds at the
work site, leading to inconvenience and inapplicability.
[0009] Because there is no locking feature provided for the
existing twisting roller and because the wires present excellent
flexibility and sliding properties, the wire ends are possibly
loosened, leading to inconvenient carrying and time-consuming
rearrangement. Some users insert the wire ends into the winding
wires, but find it difficult to search for them.
[0010] Thus, to overcome the aforementioned problems of the prior
art, it would be an advancement in the art to provide an improved
structure that can significantly improve efficacy.
[0011] Therefore, the inventor has provided the present invention
of practicability after deliberate design and evaluation based on
years of experience in the production, development and design of
related products.
BRIEF SUMMARY OF THE INVENTION
[0012] There is improved efficacy of the present invention.
[0013] Based upon innovative structures, the baffle plate or
housing of the twisting roller is provided additionally with a
locking groove and cutting groove. The wires can be pulled through
the cutting groove of the shield for direct cutting. As such, the
operators could rapidly finish the cutting action more efficiently
and safely without the need of other tools or a cigarette
lighter.
[0014] After the wires are cut, the wire ends are locked securely
into the locking groove, and a portion is exposed for convenient
operation and fixation.
[0015] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.

DETAILED DESCRIPTION OF THE INVENTION
[0028] The features and the advantages of the present invention
will be more readily understood upon a thoughtful deliberation of
the following detailed description of a preferred embodiment of the
present invention with reference to the accompanying drawings.
[0029] FIGS. 1-3 depict the first preferred embodiment of twisting
roller with wire ends locking and cutting mechanism. The twisting
roller 10 comprises a spool 11 (a circular shaft in this
embodiment) for winding of wires 12 (e.g. nylon wire). Both ends of
the spool 11 are provided separately with an expanded baffle plate
13 (a disc in this embodiment). A cutter 20 and a shield 30 are
placed at one end of at least one baffle plate 13 of the twisting
roller 10. The single-blade cutter 20 is assembled between the
baffle plate 13 and shield 30. A locking groove 31 and a cutting
groove 32 are assembled at both sides of the shield 30. The locking
groove 31 locks the wire 12 (e.g. U-shaped), so that the blade 21
of said cutter 20 is exposed to the cutting groove 32 for cutting
wire 12.
[0030] The baffle plate 13 of the twisting roller 10 is provided
with a trough 14 for accommodating the cutter 20 and shield 30. As
such, the cutter 20 and shield 30 present smoothness after
assembly, meanwhile the cutter 20 is embedded (shown in FIG. 3) to
avoid hurting the users.
[0031] Furthermore, the baffle plate 13 of the twisting roller 10
is provided with a button 15, whilst assembly holes 22, 33 are
placed opposite to the cutter 20 and shield 30. So, the cutter 20
and shield 30 are assembled and positioned on the baffle plate 13
of the twisting roller.
[0032] Referring to FIGS. 4 and 5, the wire 12 can be pulled
through the locking groove 31 of the shield 30, then pulled through
the cutting groove 32, and cut off by the blade 21 of the cutter
20, so that the wire ends are locked into the locking groove 31 and
protrude (shown in A of FIG. 5) for convenient operation.
[0033] FIGS. 6, 7, 8, and 9 depict the second preferred embodiment
of a twisting roller with wire ends locking and cutting mechanism.
The twisting roller 10 comprises a spool 11 for winding of wire.
Both ends of the spool 11 are provided separately with an expanded
baffle plate 13. A housing 40 is assembled externally onto the
twisting roller 10. A hanging piece 41 is placed on top of the
housing. Hanging hole 412 and holding hole 413 are arranged onto
the hanging piece. A locking groove 51 and a cutting groove 52 are
assembled at both sides of the hanging piece 41, while the blade of
cutter 60 is enabled to be exposed into the cutting groove 52. The
housing 40 of the preferred embodiment is composed of two
semi-circular housings 401 and 402, so that button 42 and locking
hole 43 are arranged on the assembly surface. Moreover, a recession
53 is placed laterally onto the cutting groove 52. A positioning
pin 54 is placed into the recession, enabling assembly and
positioning with the cutter 60 of positioning slot 61. A convex
portion 44 is placed at both ends of the housing 40 and used to
prevent the wire 12 being trapped between the housing 40 and
twisting roller 10.
[0034] FIGS. 10, 11, and 12 depict the third preferred embodiment
of a twisting roller with wire ends locking and cutting mechanism.
The difference from the second preferred embodiment is that the
housing 40B is of a single .PI.-shaped structure. A flexible
clipping arm 45 is extended towards the bottom of both ends of the
housing 40B, while a cylindrical axle block 46 protrudes at two
ends of the clipping arm opposite to clipping arm 16 at the center
of twisting roller 10. So, the axle block inserted into axle hole
16 (shown in FIG. 12) allows the housing 40B to be coupled with the
twisting roller 10. Similar to the second preferred embodiment, a
recession 53B is placed laterally onto the cutting groove 52B. A
positioning pin 54B is placed into the recession, enabling assembly
and positioning with the cutter 60 of positioning slot 61. A convex
portion 44B is placed at both ends of the housing 40B and used to
prevent the wire 12 being trapped between the housing 40B and
twisting roller 10.
[0035] The cutting and fixing methods and the operating principle
of the second and third preferred embodiments are the same with the
first one.
