 Moving platform/target system

Details
Inventors: Beyer, Christopher P.; Niebel, Kevin;
Assignee:
Primary Examiner: Grieb; William H.

Attorney, Agent or Firm: Kroll; Michael I.

A moving platform/target system (10) for traveling along a predetermined path. The moving platform/target system (10) includes a track (14) defining a predetermined path and a platform (12) engaging the track (14) for movement along the track (14). The platform (12) includes a housing from which wheels (22) extends from opposite sides thereof and facing parallel to the track (14). A guiding device (26, 28) extends from the housing and engages the track (14), retaining the platform (12) in alignment with the track (14). A power circuit (62, 64, 66, 68, 70) is positioned within the housing and is connected to turn the wheels (22) and impart motion to the platform (12). A sensor (32) senses a position of the platform (12) and pauses the forward motion upon sensing a predetermined position along the track (14). The sensor (32) constantly transmits a position signal which is reflected back towards the sensor (32) upon passing of reflectors (16) positioned along the length of the track (14) wherein movement of the platform (12) is ceased for a predetermined time period upon receipt of a reflected signal. The motion of the platform (12) may also be ceased in the same manner using a second sensor (84) and additional reflectors. Furthermore, the pause time of the platform (12) is adjustable as its speed. Control of the platform's movement may be remotely through a transmitter device (126) and the platform (12) may also house a second motor (122) for moving the platform (12) in a forward, reverse, left and right direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIGS.
1-6 and 11, a preferred embodiment of the mobile platform/target system of the present invention is illustrated.
Specifically, FIG.
1 shows a preferred embodiment of the mobile platform/target system indicated generally by the numeral 10.
The system 10 includes a moving platform 12 and a path or track 14 along which the platform 12 moves.
Positioned on a first side of and along the length of the track 14 are a plurality of pause reflectors 16.
Positioned at either end of the track on a side opposite the plurality of pause reflectors 16 is a single stop reflector (not shown).
The moving platform 12 is preferably in the form of a rectangular box, although any shape which is able to perform the necessary functions and house the necessary components as will be described hereinafter may be used.
Positioned on each elongated side 18, 20 of the platform 12 and in parallel alignment with the track 14 are wheels 22.
Connected to the front face 24 of the platform 12 and extending downward to engage the track 14 is a first guide assembly 26.
A second guide assembly 28 extends from a back side 30 of the platform 12 also engaging the track 14.
On the first elongated side 18 of the platform 12 and facing perpendicular thereto is a pause sensor 32 for sensing the presence of each of the plurality of pause reflectors 16 as the platform 12 travels along the track 14.
The pause sensor 32 pauses the movement of the platform 12 upon sensing the passing of one of the plurality of pause reflectors 16.
The pause period may be varied and is normally in the range of 0-60 seconds.
On the front face 24 of the platform 12 is a control panel 34 which will be discussed in more detail hereinafter with specific reference to FIGS.
3-6.
When the system 10 is used for target practice or in a shooting tournament, a target 36 may be secured to a top side 38 of the platform 12.
FIG.
2 shows the pause sensor 32 and first guide assembly 26 in more detail
