Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a holding apparatus and
more particularly to an apparatus for holding a line, such as an
electrical extension cord, to provide slack therein, where the
apparatus is simply constructed, inexpensive and easy to use.
[0003] 2. Description of the Related Art
[0004] Some electrically driven tools must be used far from a power
source, such as an electrical outlet. For example, an electric
garden tiller is an outdoor tool that is likely to be used at a
distance from an electrical outlet mounted to the outside wall of a
house. To solve this problem, electrical extension cords are used.
These extend from the wall outlet to the electric tiller. The
tiller typically includes an electrical plug, and the extension
cord is connected to the tiller plug to cause a hook up of
electrical power. During operation of the tiller, it is constantly
being moved. This requires the user to monitor the cord very
carefully. Careful attention to the cord is necessary both to
ensure that the cord is not damaged by the tool nor inadvertently
unplugged. A sudden, rough separation could damage the cord, and/or
the tiller plug.
BRIEF SUMMARY OF THE INVENTION
[0005] The problems mentioned above have been solved by the present
invention which is a line holding apparatus comprising a base or
back portion having upper and lower sections, the base portion
being positioned to be supported by material worn by a user, a flap
or front portion connected to the upper section of the base portion
and extending generally parallel to the base portion but spaced
away therefrom, the flap portion having an upper section and a
lower section and the flap portion being positioned on an opposite
side of the material from the base portion, and a clip portion
connected to the flap portion, the clip portion also having an
upper section and a lower section, the lower section of the clip
portion forming with the flap portion a region for supporting and
restraining a line, the clip portion being able to flex away from
the flap portion in response to the insertion of a line into the
supporting and restraining region.
[0006] There are a number of advantages, features and objects
achieved with the present invention. For example, one advantage is
that the present invention captures and controls a cord so that a
user can safely maneuver without interference from excess cord.
Another feature is that the present invention is simply
constructed, inexpensive and easy to use. A further feature of the
present invention is the provision of a line or cord holding
apparatus which is reliable and effective. Yet another object of
the present invention is to provide a cord holding apparatus which
maintains the cord in a slack condition between a user and a tool
or item to which the cord is connected so as to prevent tension at
the connection between the cord and the tool, even when there is
increased tension in the cord between the user and the end of the
cord that is opposite the tool.
[0007] A more complete understanding of the present invention and
other objects, advantages and features thereof will be gained from
a consideration of the following description of a preferred
embodiment read in conjunction with the accompanying drawing
provided herein. The embodiment represents an example of the
invention which is described here in compliance with Title 35
U.S.C. section 112 but the invention itself is defined by the

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
[0014] While the present invention is open to various modifications
and alternative constructions, the preferred embodiment shown in
the drawing will be described herein in detail. It is understood,
however, that there is no intention to limit the invention to the
particular embodiment, form or example disclosed. On the contrary,
the intention is to cover all modifications, equivalent structures
and methods, and alternative constructions falling within the
spirit and scope of the invention as expressed in the appended
claims, pursuant to Title 35 U.S.C. section 112 (second
paragraph).
[0015] Referring now to FIGS. 1 and 2, a line or cord holding
apparatus 10, also referred to as a belt clip, is shown as a
unitary device having a back or base portion 12, a front or flap
portion 14 and a clip portion 16. As shown in FIG. 1, the line
holding apparatus is supported by a user 18 by being mounted to his
belt 20. This is accomplished by having the back portion 12 and
front portion 14 straddle the belt with the back portion located
between the belt and the user and the front portion being adjacent
the opposite side of the belt, the one facing away from the user.
The apparatus can also be hung from a pocket, a tool loop, the top
of a pair of pants or a convenient edge of overalls. Broadly, any
material worn by a user may serve as a support to the belt clip.
The apparatus 10 may be constructed from a suitable plastic, such
as ABS plastic, metal or a combination of material having
resilience and durability.
[0016] A line, such as an electrical extension cord 21, is received
between the clip portion and the front portion of the holding
apparatus so as to fit snugly as shown in FIG. 6. The user ensures
there is a slack portion 22 of the extension cord 21 between
him/her and an electrical device or tool being operated, such as a
garden tiller 24. The garden tiller may include a short electrical
line 26 and a plug 28. An extended end 30 of the extension cord 21
is connected to the plug 28 of the electric tiller. An opposite end
32 of the extension cord may be engaged with a power source, such
as an electrical outlet 34 attached to the outer wall of a house or
mounted to an electrical conduit buried in the ground.
[0017] It can be easily appreciated that should the user
inadvertently attempt to move the tiller beyond the length of the
extension cord, the cord will develop tension and disengage from
the tiller or from the outlet. This may damage the cord, its plug
or the plug or line of the tiller. However, with the line holding
apparatus 10 and the slack portion 22 in the extension cord, the
user 18 will feel tension at his/her belt 20 before any tension is
passed to the extended end 30 of the cord or to the tiller plug 28.
Once the user feels the tension at the belt, he/she will be
notified that the extension cord has been extended to its maximum
usable length. Thereafter the user must use another cord or change
outlets. Thus, there will not be an inadvertent unplugging of the
electric tiller nor any damage to the tiller plug 28 or to the line
26 or to the extension cord 21 because of a rough disengagement. In
addition, the user can maintain greater control of the extension
cord to minimize the risk of damage to the cord from the tiller
because that portion of the cord nearest the tiller is restrained
away from the tiller's spinning tines.
[0018] Referring back to FIGS. 2-6, the back portion 12 is formed
as an open rectangular frame having an upper section 40 and a lower
section 42. The rectangular frame includes a lower short arm 44, an
upper short arm 46, a left long arm 50 and a right long arm 52.
Surrounded by the arms is an open middle portion 54. Extending from
the lower short arm 44 is a shoulder projection 56. As the upper
and lower sections have been defined, moving between the left and
right long arms is defined as the lateral direction.
[0019] The front portion is also an open rectangular frame having
an upper section 60 and a lower section 62. The rectangular frame
includes an upper short arm 64, a lower short arm 66, a left long
arm 68 and a right long arm 70. The frame defines an open middle
portion 74. It may be seen from the drawing that the rectangular
frame of the front portion of the line holding apparatus is smaller
than the rectangular frame of the back portion. The front portion
is connected to the back portion so as to be flexible by having the
upper section 60 of the front portion extend from the upper section
40 of the back portion. Flexing may occur when the line holder is
hooked onto a user's belt.
[0020] The clip portion of the line holding apparatus is a bent
strip in the shape of the letter "S" as best seen in FIGS. 3 and 6.
The clip portion 16 has a lower section 80 which extends from the
lower section 62 of the front portion. The clip portion is also
formed so as to flex in use. The clip portion 16 includes a surface
82 operating as a cam follower to the cord acting as a cam. The
surface 82 is responsive to the downward force of the extension
cord 21 as shown in FIG. 6; the cord starts in the upper position,
exemplified by the cord 21a and is pushed downwardly to the portion
shown by the cord 21b. The downward force flexes the clip portion
to the right, shown in broken line and labeled 16a, allowing the
cord to be disposed in a region 94, FIG. 3, between the clip
portion and the front portion where the cord is supported and
restrained. Because of the relevant dimensions, the cord, such as a
twelve, fourteen or sixteen gauge extension cord, is squeezed in
the region 94 so as to create a snug fit between the cord and the
line holding apparatus.
[0021] As best seen in FIG. 5, both the back portion and the front
portion are curved in the lateral direction so as to fit more
comfortably to the belt or other material worn by the operator.
[0022] The shoulder 56 prevents the inadvertent dismounting of the
line holding apparatus 10 from the belt 20, FIGS. 1 and 6, of the
user. For example, if the holding apparatus is tugged upwardly, a
bottom edge 102 of the belt 20 abuts the shoulder 56 and prevents
removal. If the apparatus is tugged downwardly, an upper end 104 of
the belt engages an inner surface 106 of the front portion of the
apparatus.
[0023] In operation, the user 18 supports the line holding
apparatus 10 by mounting it to his/her belt so that the back
portion 12 is to one side of the belt and the front portion 14 is
to the other side. This mounting arrangement is secure on the belt
because any downward or upward pull on the line holding apparatus
will cause an edge of the belt to engage or abut parts of the
apparatus. The user creates a slack portion of the cord between
himself and the electric tool or device he/she is operating and
then pushes the cord against the cam follower surface of the clip
portion 16 until the cord is received in the region 94. In this
region the cord is squeezed so as to be both supported and
restrained.
[0024] The user next plugs the cord into the plug 28 of the tiller
24. In normal use, should the user stretch the extension cord to
its limit, he/she will feel a tension at the belt before there is
ever an undesirable tension at the plug 28. This feature of the
apparatus prevents any damage to the tiller plug or line because of
an inadvertent rough disengagement caused by tension in the
extension cord. The apparatus or belt clip also minimizes damage to
the cord by placing the cord away from the tiller while the tiller
is being operated by the user.
[0025] The above specification describes in detail a preferred
embodiment of the present invention. Other examples, embodiments,
modifications and variations will, under both the literal claim
language and the doctrine of equivalents, come within the scope of
the invention defined by the appended claims. For example, while
the line is described as an extension cord, other types of lines,
cables or the like may be used. Also, while a belt is described,
the line holding apparatus may also be supported by a web, a loop
of material, an edge of an garment, such as the top of a pair of
pants or the edge of a pair of overalls. Even a pocket opening may
be used. Also, the garment or material being worn may be located
along a user's side or, like a pocket, adjacent the user's back.
Still other alternatives will also be equivalent as will many new
technologies. There is no desire or intention to limit in any way
the application of the doctrine of equivalents nor to limit or
restrict the scope of the invention.
