Abstract: A light projecting device for selectively providing a light beam in at least two shapes. The light projecting device includes a light projecting source contained within a housing including a first end through which the light projecting source transmits a light beam. The device further includes a lens switch secured to the first end of the housing permitting the light beam to pass through a primary opening in the lens switch, while the lens switch controls the shape of the light beam projected from the light projecting device.

Abstract: A golf club laser alignment device for attachment to a golf club having a face. The alignment device includes a mounting bracket supporting a laser assembly above the face of a golf club for properly aligning a golf club. The mounting bracket includes a distal end adapted for attachment to the face of a golf club and a proximal end supporting the laser assembly. The device is further provided with a laser assembly including lateral adjustment rings permitting the laser assembly to be selectively adjusted along the face of a golf club. In use, the device is selectively attached to the face of a golf club, the device is then laterally and rotationally adjusted relative to the face of the golf club and the laser alignment device is activated to confirm the alignment of the golf club.

Abstract: An internally mounted laser beam gun sight suitable for use in automatic pistols is provided by replacing the conventional recoil spring guide rod with a hollow tube having substantially the same exterior shape and dimensions, but containing a laser beam generation module, batteries and an on/off switch within its hollow bore. In a preferred embodiment, the hollow tube has two portions which are movable with respect to each other. A first portion contains the batteries and a second portion contains the laser module. An insulated bushing containing a central electrical contact is located between the two portions. In the preferred embodiment, the central contact forms part of an internal electrical switch which is activated by relative motion of the first and second portions of the guide tube to turn the laser beam on and off.

Abstract: A combined light pointer and marker comprises a replaceable pen, an energy supply, a light source and an ON/OFF switch. When the light pointer is in use the tip of the pen is covered or retracted. Conversely, when the tip of the pen is exposed, the light source is deactivated. In a preferred embodiment, conductors in a pen cap engage conductors in the pen and light source housing, thereby making energy available in the housing from batteries desirably located in the cap. When the cap is removed to expose the pen tip for writing, the connection between the conductors is broken, battery energy is no longer available in the housing, and depressing the ON/OFF switch cannot activate the light source. This provides an important safety feature.
