Abstract
A laser targeting apparatus rests on a surface and moves, such as by vibrating, wobbling, or shaking, when struck by laser light of sufficient intensity. The apparatus is designed not to fall over, so a user does not have to move to the apparatus and pick it up after a strike. The apparatus has a body that includes a structure, which is preferably one or more printed circuit boards including light sensors, for detecting strikes of laser light, and a motor. When a strike of laser light is detected, power is provided to the motor, which vibrates and causes the apparatus to move.
Description
FIELD OF THE INVENTION

The present invention is related to targets that detect strikes of laser light, rather than targets that are struck with projectiles such as bullets.


SUMMARY OF THE INVENTION

A laser targeting apparatus rests on a surface and moves, such as by vibrating or shaking, when struck at certain locations by laser light. The apparatus is designed not to fall over, so a user does not have to move to the apparatus and pick it up after a laser light strike. The apparatus has a body that houses a laser light detector, which is preferably one or more printed circuit boards, for detecting strikes of laser light, and a motor. The apparatus is typically used for aiming or sighting purposes with a gun that fires laser light instead of projectiles. This is often accomplished by using a standard gun with a laser light trainer cartridge, which is known to those in the art. When a strike of laser light is detected, power is provided to the motor, which causes the motor to vibrate and in turn causes the apparatus to move.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Turning now to the drawings, where the purpose is to describe preferred embodiments of the invention and not to limit same, FIG. 1 shows an exploded view of a preferred embodiment of the invention. Apparatus 10 has a housing 12 with an annular outer surface 14, an annular inner surface 16, and three fastener retention grooves 18 that, as shown, are equally, radially spaced along inner surface 16. Housing 12 may, however, be of any suitable shape or size. Housing 12 is preferably clear (or translucent and colored red, which helps filter ambient light, but permits red laser light to pass through), so that red laser light can pass through it and be detected. Housing 12 has a top opening 20 and a bottom opening 22.


A top cap, or top, 30 functions to seal top opening 20 and to retain a portion of a motor sleeve. Top cap 30 has a flat, sealing portion 32 that has an upper surface 32A and a lower surface 32B. Top cap 30 includes three apertures 34 that align with fastener retention grooves 18 when placed on top opening 20 of housing 12. When assembled, fasteners 33 pass through apertures 34 and are retained in grooves 18 to attach top cap 30 to housing 12.


Top cap 30 includes three downwardly-extending prongs 36 that fit inside of housing 12 and fit inside of a space between printed circuit boards 90 to help to support them. Top 30 also includes a downward-extending retainer 38 that has a cavity 40 for receiving part of the motor sleeve in a preferred embodiment, as discussed below.


Motor 40 is a known type of vibrating motor, or wobble motor. Motor 40 has a first end 42, a second end 44, and body portion 46. A motor sleeve 50 is made of elastomeric material and is preferably comprised of soft or semi-rigid rubber or plastic. Sleeve 50 has a first end 52, a second end 54, a body 56 and an opening 58 therethrough. Body 56 has a first portion 57 with a first diameter and a second portion 59 with a second diameter, wherein the second diameter is less than the first diameter. Extensions 56A are positioned on and extend outward from first portion 57, and have apertures 56B for receiving fasteners 80.


Motor cap 64 is preferably comprised of a soft or semi-rigid plastic or rubber. Motor cap 64 as shown has an annular body 66 and an opening 68 extending therethrough. Extensions 70 are positioned on and extend outward from body 66. Each extension 70 has an aperture 70A for receiving a fastener 80.


When assembled, end 42 and at least some of body portion 46 of motor 40 are received in opening 58, and retained in sleeve 50. Cap 64 is pressed against end 44 of motor 40 and fasteners 80 pass through apertures 70A, 56B, and are received in apertures 38A to create a motor assembly that is connected to retainer 38 of top 30. Second portion 59 of sleeve 56 is then retained in cavity 40 to provide lateral support to the motor assembly, and to help transfer vibration of motor 40 to top cap 30 and body 12.


Printed circuit boards 90 include light sensors that detect strikes of laser light. In this embodiment, there are three printed circuit boards arranged in a triangular fashion, and they may be connected by fasteners 92. In this embodiment, at least part of motor 40 and sleeve 50 are positioned in the space between printed circuit boards 90 when apparatus 10 is assembled. Although three circuit boards arranged in a triangular shape are shown, any suitable member, type, or shape of printed circuit boards may be utilized. Also, any one or more devices may be utilized in place of printed circuit boards 90, wherein the one or more devices detect laser light strikes and cause power to flow to motor 40, thereby activating motor 40, as a result. As shown, each printed circuit board is planar and rectangular with four sides.


A bottom, or bottom cap, 200 retains a power source 100, which is preferably a 9V battery, but can be any suitable battery(ies) or other power source. Apparatus 10 may also utilize electric power accessed through an outlet via a wired connection. A battery attachment 110 attaches to the negative and positive posts of the 9V battery in this embodiment, in order to transfer power from the battery. In this preferred embodiment, cap 200 also retains a switch 150 that switches power on or off from power source 100 and that is retained in bottom cap 200 by fasteners 160.


Bottom 200 has a first portion 222, which as shown is rectangular, and a second portion 224, which as shown is circular and seals the bottom of body 12 when apparatus 10 is fully assembled.


Bottom 200 has a battery door 210 that is retained on the bottom side of bottom 200 by fasteners 220, and can be removed to replace power source 100, which is positioned in cavity 230.


Turning now to FIGS. 2 and 3, apparatus 10 is shown assembled, with an outer adhesive coating 300 on outer surface 20 of body 12 to define elliptical areas.


When laser light of sufficient intensity strikes one of the areas 302, it passes through body 20 and strikes one of the printed circuit boards 90. A light sensor on the printed circuit board 90 that is struck causes the printed circuit board 90 to activate circuit 150 and cause power to flow from power source 100 through the printed circuit board 90 that was struck with laser light to motor 40. Motor 40 then vibrates, preferably for a period of 3-5 seconds. The vibration of motor 40 is transferred to body 12 of apparatus 10 as previously described, causing apparatus 10 to vibrate or wobble without falling over.


Having thus described some embodiments of the invention, other variations and embodiments that do not depart from the spirit of the invention will become apparent to those skilled in the art. The scope of the present invention is thus not limited to any particular embodiment, but is instead set forth in the appended claims and the legal equivalents thereof. Unless expressly stated in the written description or claims, the steps of any method recited in the claims may be performed in any order capable of yielding the desired result.
