Description
BACKGROUND OF THE INVENTION
This invention relates to a novel backstop target device for use in
retaining balls or the like which are aimed thereat during
practice. While the invention will be described with respect to a
baseball backstop, it will be understood that it has application to
such practice target installations as those simulating a hockey
goal, etc.
A large number of backstop devices are known to the art. Among such
devices are those described by Ziel in U. S. Pat. Nos. 2,254,986
and 2,873,969. These backstop devices are targets, relatively
heavy, and have no means for collecting the balls. Another group of
backstop devices is illustrated by those disclosed in U. S. Pat.
Nos. 3,206,196 to Jackson and 2,944,816 to Dixon. These devices
comprise a spring-like target which is sufficiently resilient to
repel the ball towards the direction from which it was thrown.
A number of other devices have been developed to aid the baseball
player. These include an electronic pitch-monitoring device, such
as that disclosed in U. S. Pat. No. 3,229,975. Another device
disclosed in the art is for use in a game and comprises a complex
of retainer tubes at the bottom of the device to serve to catch
balls thrown into a hood-like chamber. The tubes serve as a score
determining means.
In general, the devices of the prior art have been more suitable
for semi-permanent installation and have lacked that portability
appropriate for apparatus to be handled by a boy. Moreover, the
bounce-back features have pre-supposed a relatively flat surface
about the area in which the practice device is to be used. While
this is often the case, the location of such devices is restricted
in many ways when a bounce-back feature is used. For example, the
target cannot be positioned on a driveway which slopes to a street,
on the opposite side of a flower garden or swimming pool from the
thrower, and so forth.
These are some of the problems which the inventor attempted to
avoid. In so doing, it will be seen, apparatus was developed which
also has other decided advantages.
SUMMARY OF THE INVENTION
It is a principal object of the invention to provide an improved
target device for use with projectiles of relatively low velocity,
for example projectiles of less than 200 miles per hour.
Another object of the invention is to provide a target practice
device which comprises a restraining means and is relatively easy
to assemble, install, and move about.
Still another object of the invention is to provide a lightweight
target-practice device which is relatively quiet in use.
Other objects of the invention will be obvious to those skilled in
the art on their reading this application.
The above objects have been substantially accomplished by the
construction of a simulated target backstop device which includes a
nestable member comprising both a target face and a restraining
rim. In general, such a device can resemble a child's plastic
wading pool and be selected of whatever size is appropriate for the
particular target to be simulated. The lower portion of the rim
holds a fencing means, such as a plastic webbing. The fencing
means, together with an adjacent portion of the rim, forms means to
collect balls impacted against the target face. Support means are
utilized to hold the nestable member in upright position.
It is particularly advantageous to utilize the restraining fence to
hold a target indicating means. For example, the fence means can
hold a baseball "home plate" as a sighting target, or guide,
mounted in front of a "catcher's mitt" or "strike zone" target. The
sighting target is advantageously detachably mounted so it can be
positioned relative to the particular habits of given players, say
given batters or catchers.
Another advantageous embodiment of the invention is that wherein
the target face (or reverse side thereof, or both) is covered, at
least in part, with a material that will form means to distribute
the impact forces against the target face. Use of such a material,
advantageously a material based on an organic plastic or resin,
will help avoid easy denting or make use of a thinner structure
material and consequently permit the construction of lighter
targets. Moreover, such a facing is advantageously thick enough and
sufficiently absorptive of energy to provide means to prevent the
target apparatus from being excessively noisy during use. Among the
organic polymer and organic resin based coatings which are useful
are those based on polyurethane formulations and those based on
flexible thermoplastics, such as polyethylene and polypropylene.
These coatings can be solid in the form or formed of open-cell or
closed-cell foams. Where noise avoidance is particularly important,
one or more such plastic layers may be formed of such compositions
as poly(vinylacetate), poly(vinyl chloride), or the like, highly
loaded with carbon black. Such highly loaded materials provide
extraordinary energy absorbing characteristics.
it should be noted that these coatings or covering layers may be
selectively placed. For example, it may be advantageous to put a
sound absorbing coating only over those areas of the target face
that represent a hit or miss so that the sound or lack thereof will
be indicative of a hit or miss. This would be of particular value
for use in target applications wherein the projectile comes in at
different angles and at very high speed. Hockey targets would be a
good example of this.
The nestable target section can be formed of moldable thermoplastic
materials, as is known in the art, or it may be drawn from
laminated sheets. Alternately, the nestable shell can be formed of
glass-fiber reinforced polyester, or from sheet metal, even from
unitary flanged pie-plate type structures. The exact thickness of
the basic structure will be dependent on the size of the intended
target area with a reasonable allowance for target-missing
projectiles, the type and velocity of projectile to impact
thereon.
Apertures can be cut into the target face and, in such a case, it
is desirable to have a container on the back of the target to
collect the projectile.
ILLUSTRATIVE EMBODIMENT OF THE INVENTION
In this application and accompanying drawings there is shown and
described a preferred embodiment of the invention and suggested
various alternatives and modifications thereof, but it is to be
understood that these are not intended to be exhaustive and that
other changes and modifications can be made within the scope of the
invention. These suggestions are selected and included for purposes
of illustration in order that others skilled in the art will more
fully understand the invention and the principles thereof and will
be able to modify it in a variety of forms, each as may be best
suited in the condition of a particular case.
IN THE DRAWINGS
FIG. 1 is a front elevation of a simulated target device according
to the invention;
FIG. 2 shows a side elevation, partly in section, of the apparatus
of the invention showing a typical multi-layer construction, a
target aperture and a collecting means;
FIG. 3 shows the side view of a fragment of an alternate target
face arrangement.
Referring to FIG. 1, it is seen that a large molded sheet 11 of a
polyolefin thermoplastic has been molded into a simulated target
apparatus 10 comprising a flat, circular bottom, or target face
section, 12 including both the target area, or strike zone, 14 and
a marginal area 16. Apparatus 10 comprises an integrally molded,
outwardly flared, annular flange, or rim, member 17 which, in
conjunction with a fence of flexible plastic netting 18 forms a
projectile retaining means or baseball collecting means. It will be
seen that bottom chordal base segment 20 of rim 17 has been
flattened and is thereby adapted to be positioned against a floor
or the ground by any suitable fastening means, for example ground
anchors 24. A sighting target 22, such as a simulated home plate,
is mounted on netting 18.
Face 26 is covered with a shock absorbing material, such as
closed-cell, resilient, ethylene-vinylacetate copolymer foam 29
about 0.06 inches in thickness. Such a sheet product is available
from Proctor Laminar, Inc., of St. Louis, Mo. On this material is
painted the target face 12.
The foam material is resilient and forms a means for both absorbing
and distributing stress under impact of projectiles such as
baseballs which will be thrown against the target. In the apparatus
of FIG. 1, there is an aperture 28 in the target face section
through which a baseball properly pitched into the strike zone will
pass into the ball collection bag.
FIG. 2, partly in section, illustrates a side view of the apparatus
in FIG. 1. It will be seen that ball collection means in the form
of a container comprising a flexible bag 30 and a flange 32 has
been placed into aperture 28 and forms a collecting means 34 for
any projectiles passing through the aperture 28. Moreover, it is
seen that a foldable brace 36 is pivoted to the rear face of bottom
12 to fold flatwise thereagainst to support the device in erected
position.
The ball collection means, or projectile retaining means, 34
includes either, or both, of the elongated, compressible, fabric or
net bag, or bags, 30 and the receptacle 50 formed by the
compressible, fabric, or net, fence 18 with the segment 52 of the
flange 17. Both collect and retain the baseballs 54 and both may be
detachably affixed to the target 10 by suitable hooks, or clips, 56
in holes 58. Similarly, the sighting target 22 may be detachably
affixed to the fence 18 by clips 56, whereby the device is easily
erected or dismantled and stored in compact nested condition.
Also seen in FIG. 2 is the multi-ply wall structure comprising
plastic foam 29 and a molded sheet 11.
FIG. 3 shows a fragment of an alternative target structure 40.
Structure 40 includes a plurality of apertures 42 in the strike
zone. However, its primary difference is seen in the fact that the
structure comprises a polyethylene layer 44 of about 0.050 mils
thick, a poly(vinylchloride) sheet 46 heavily filled with carbon
black to assure sound dampening properties, on a sheet of aluminum
48.
It is also to be understood that the following claims are intended
to cover all of the generic and specific features of the invention
herein described and all statements of the scope of the invention
which might be said to fall therebetween.
