Abstract
An arrow extraction device includes a clamp and a lever-actuated push rod. An arrow shaft is held by the clamp while removal force is applied through the lever-actuated push rod, thereby facilitating easy recovery of a whole arrow embedded in a target.
Description
FIELD OF THE INVENTION
This invention relates generally to auxiliary tools or devices for archery. In particular it relates to tools or devices for extraction of arrows from foam targets.
DESCRIPTION OF THE RELATED ART
There has always been a need in archery for tools to extract arrows from targets without breaking the shaft. The development of more powerful bows and deeply penetrating arrowheads has merely increased this need. When the arrowhead is fully embedded in a target, manual removal of the arrow is difficult. In such instances, arrow extraction risks breaking the shaft, is time-consuming and requires substantial force.
Arrow and arrowhead extractors are known in the art. Orton et al., U.S. Pat. No. 3,826,471, disclose a gripping tool for extraction of exposed arrowheads. Roberts et al., U.S. Pat. No. 5,205,541, disclose a device for extracting arrowheads embedded in the target. Roberts' extractor engages threaded arrowheads manufactured for engagement of threaded, receiving shafts. Accordingly, Roberts' extractor device is used after first unscrewing the arrow shaft from the embedded arrowhead and then inserting the extractor into the target and screwing the device onto the embedded arrowhead. Bulot, U.S. Pat. No. 5,546,621, discloses a manual device that grips the arrow shaft and manually removes the arrow from foam targets.
While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe a device that will amplify the removal force to extract a deeply embedded arrow, one without the arrowhead exposed, from a foam target or other object.
BRIEF SUMMARY OF THE INVENTION
The invention relates in general to an arrow extraction device that includes a clamping means and a lever-actuated push rod. An arrow shaft is held by the clamping means while removal force is applied through the lever-actuated push rod, thereby facilitating easy recovery of a whole arrow embedded in a target.
Thus, the arrow extractor according to the present invention substantially departs from the conventional concepts and designs of the prior art by providing an apparatus that rapidly and with little effort extracts a whole arrow from the target object, i.e. without unscrewing or detaching the shaft from the embedded arrowhead. Hence, the risk of breaking the shaft during removal is minimized.
A principal objective of this invention is to provide a reliable, simple and inexpensive device that easily and quickly removes embedded arrows from foam targets and other objects without causing damage either to the arrowhead or shaft.
Another objective of the invention is to provide an arrow extractor that utilizes a clamp and lever action requiring less force than that required to remove the embedded arrow by grasping and pulling it out manually.
Another goal is a new and improved device for withdrawing arrows which possess completely embedded arrowheads from foam targets and the like.
Yet another objective is an arrow extractor that provides an easy means of gripping the arrow shaft for removal of the embedded arrow from a target object.
Various other purposes and advantages of the invention will become clear from its description in the specification that follows and from the novel features particularly pointed out in the appended claims. Therefore, to the accomplishment of the objectives described above, this invention consists of the features hereinafter illustrated in the drawings, fully described in the detailed description of the preferred embodiment and particularly pointed out in the claims. However, such drawings and description disclose but one of the various ways in which the invention may be practiced. All publications cited are hereby incorporated by reference in their entirety herein.

DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION
The present invention features a unique clamp and lever structure that enables one to easily and quickly extract an embedded arrow from foam targets and other objects while utilizing less force than by grasping and pulling it out manually.
Referring to the drawings, wherein like parts are designated throughout with like numerals,
FIG. 1
illustrates in side elevation view an arrow extractor device
1
according to the invention. The device
1
includes a shaft clamp lever
10
with a proximal gripping end
12
, a central portion
13
having a bottom surface
14
, and an engaging end
15
.
To assist the user in grasping an arrow shaft
11
, the arrow shaft clamp lever
10
can include a modified distal gripping end
12
that extends upwardly away from the plane of the central portion
13
at a predetermined angle. For example, bending the gripping end
12
of clamp lever
10
to an angle
17
of about 170 degrees will assist with manual engagement of an arrow shaft by providing ample space for hands of different sizes to grasp the gripping end
12
. Fixedly positioned on the bottom surface
14
of the central portion
13
is an upper arrow-shaft holder
18
.
The arrow-shaft clamp lever
10
has an engaging end
15
hingedly connected to a support member
20
through a clamp lever pivot bolt
22
, which can be held in place by a fastening means such as a nut
23
(not shown in this view; see FIGS.
2
and
3
). The support member
20
has an upper surface
24
to which is fixedly positioned a lower arrow-shaft holder
26
.
The arrow shaft holders
18
and
26
, along with the arrow-shaft clamp lever
10
and support member
20
, together form an arrow-shaft clamping means
27
. In the preferred arrangement, the holders
18
and
26
are disposed oppositely facing according to predetermined measurements, preferably between the center portion
13
and the engaging end
15
of clamp lever
10
. The two arrow shaft holders
18
and
26
consist of channels with a concave surface
28
(see
FIG. 2
) to which preferably is attached a gripping means
29
, such as a rubber lining. Other clamping means capable of securely gripping an arrow shaft may be substituted for the preferred embodiment described above. For example, see the gripping device of U.S. Pat. No. 5,546,621.
Application of downward pressure on the distal gripping end
12
of the arrow shaft clamp lever
10
causes the lever
10
to pivot downwards against the support member
20
, bringing the arrow shaft clamping means
27
into contact with, and thereby gripping, an arrow shaft
11
. The lever action of the clamp lever
10
amplifies the gripping force acting upon the arrow shaft positioned between the arrow shaft holders
18
and
26
.
With further reference to
FIG. 1
, a ram push rod lever
30
is attached at a predetermined point to the supporting member
20
(e.g. in the middle as shown) by a lever pivot bolt
31
. The ram push rod lever
30
has a lever gripping end
32
and a lever pivoting end
33
. The lever pivoting end
33
is attached by a ram lever pivot bolt
34
to a ram push rod
40
, which has a rod pivoting end
41
and a ram pushing end
42
. Functionally, the ram push rod
40
and the ram push rod lever
30
cooperate to apply a pulling force to a target-embedded arrow clamped by the device
1
. Attached to ram pushing end
42
is preferably a ram pad
43
having a pad face
44
. The ram pad
43
reduces the pressure of the push rod
40
by enlarging the surface area that pushes against the target from which the arrow will be extracted.
A push rod alignment bracket
45
, attached by a bolt
46
or the like to the supporting member
20
, is preferably used to align the ram push rod
40
along the plane of the support member
20
, thereby maintaining the ram push rod
40
in alignment during extension and retraction. A push rod lever stop bolt
47
may be mounted to support member
20
such that the lever
30
is stopped at a convenient, ready-to-use position.
While firmly holding the arrow shaft
11
in the arrow shaft clamping means
27
, the operator grips the ram push rod lever
30
at the lever gripping end
32
and pulls it upwardly and rearwardly away from the target (as indicated by the large arrow), causing the ram push rod lever
30
to pivot on both the lever pivot bolt
31
and the ram lever pivot bolt
34
. Thus the upward and rearward pulling action simultaneously causes a pivoting action at the lever pivoting end
33
attached to the ram push rod
40
at the rod pivoting end
41
. The pivoting actions so caused force the ram push rod
40
to extend forwardly beyond the support member
20
, with the push rod alignment bracket
45
maintaining the ram push rod
40
movement in alignment (i.e. roughly parallel) with the arrow
11
.
The forward thrusting extension of the ram push rod
40
forces the pad face
44
of the ram pad
43
against the target. As the operator continues to apply upward and rearward pulling action to the lever gripping end
32
the ram push rod
40
applies and amplifies forward linear thrust against the target to extract the arrow by means of an amplified rearward substantially linear pulling force acting on the arrow at the shaft where it is gripped by the arrow shaft clamping means
27
.
Turning to
FIG. 2
, a frontal view of the inventive device
1
is depicted. In this view, the concave channel structure of the arrow shaft holders
18
and
26
is more clearly seen. Also more clearly shown is the rectangular structure of the preferred ram pad
43
. As is well understood by those skilled in the art, the engaging end
15
of the clamp lever
10
is offset from the central portion
13
and the gripping end
12
in order to provide clearance for the arrow shaft gripped between the two arrow shaft holders
18
and
26
. In
In
FIG. 3
, a rear view of the inventive device
1
is pictured. From this view, the structural relationship between the ram push rod lever
30
and the push rod
40
is shown in detail. The push rod lever
30
is pivotally attached to the push rod
40
by virtue of a bolt
34
and nuts
21
. Thus, by pulling the rod lever
30
toward the user, push rod
40
is actuated toward the target.
Various changes in the details, steps and components that have been described may be made by those skilled in the art within the principles and scope of the invention herein illustrated and defined in the appended claims. Therefore, while the present invention has been shown and described herein in what is believed to be the most practical and preferred embodiments, it is recognized that departures can be made therefrom within the scope of the invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent processes and products.
