Pen cap / low light adjustment tool for laser aiming devices

Abstract

The present invention teaches that a custom designed tool might serve as a marker cap for a standard size and diameter of marker such as a Sharpie® or Revmark® brand marker, along with an LED or low light LED or dim red LED or even infrared LED, and a hex drive socket which could then be used with an appropriate size of hex bit (such as a BITHEX™ tool head) for the exact size of adjustment screw heads found on any particular laser gun aiming device. The LED serves to light the laser aiming device screw head and the hex bit tool head, and in embodiments may be quite dim or otherwise inconspicuous.

DETAILED DESCRIPTION

Glossary

(13) For purposes of the present application, the word “dim” is defined to mean having a light output of less than 5 lumens.

(14) Infrared refers to frequencies of light not normally visible without special equipment.

(15) Hex drive refers to a socket having a hexagonal, square, pentagonal, octagonal shape into which small bits or tool heads, specifically including small screwdrivers, may be inserted.

End Glossary

(16) FIG. 1 is an oblique elevational orthogonal diagram of a first embodiment of the invention showing the hex drive without a bit installed. Body 100 is in the shape of a marker cap, having a generally cylindrical configuration with a closed end 104.

(17) Clip 102 on the side may be slightly resilient and may urge itself against the exterior of body 100, so that the device may be clipped onto fabric such as a belt, a pocket, webbing, straps and so forth, or may be clipped onto other thin objects (clip boards for example).

(18) Closed end 104 has a small space therein: hex drive socket 106. The hex drive socket 106 does not penetrate into the pen tip cavity 110. The pen tip cavity 110 (at a second, obviously open end) is dimensioned and configured to accept a particular diameter of marker. This can be keyed to a particular brand or otherwise selected and known. When the marker end is inserted into pen tip cavity 110, the inside of cavity 110 and the outside surface of the marker engage frictionally and the cap is secured. Pen tip cavity 110 is completely air tight, so when it is placed over the writing tip of the marker, the marker does not dry out.

(19) Battery cover 108 covers a standard size of coin battery/watch battery.

(20) FIG. 2 is a side view of a second embodiment of the invention showing a loom of light from a drive socket projecting around and past a hex bit in the socket.

(21) Clip 202 is now seen from a different angle. In this embodiment, battery cover 208 is located in a slightly different location as well.

(22) LED/socket 212 is seen only as part of the socket, that is, the light shines around the hex bit 214 via the transparent socket material and illuminates the area in front of the hex bit 214.

(23) Hex bit 214 is seen projecting from the socket, filling it in this embodiment. The hex bit 214 is surrounded by a modest loom of light from the indirect source of illumination.

(24) It will be noticed that the removal of the hex bit 214 may in embodiments immediately increase the amount of light provided by the LED.

(25) Knurled grip 216 provides a more secure grip in a user's fingers.

(26) The device can be used while on the marker, or removed from the marker first, as the user finds best.

(27) To use the device, the operator may remove it from the marker (as the body of the marker may have only a frictional engagement to the interior pen tip cavity and/or the body of the marker may interfere with a secure fingertip grip on the knurled grip 216). The user may also allow the device to remain on the marker, however, the marker is not torqueable due to the frictional engagement between cap and marker. Torque is not required to any great degree: the makers of the laser aiming devices engineer the devices to require micro-clicks only during the adjustment process.

(28) FIG. 3 is a cross-sectional side view of a third embodiment of the invention, similar to the second embodiment, without the bit installed in the drive socket but with marker/pen P shown disposed inside of the pen tip cavity.

(29) Body 300 has another angle shown, with clip 302 seen edge on.

(30) Hex drive socket 306 is seen in profile and cross section with the LED 312 at the bottom under the hex drive socket 306.

(31) Hex drive socket 306 may advantageously be a material which is translucent or transparent: this will be discussed further in regard to FIG. 11.

(32) Battery cover 308 is also seen edge on: in this embodiment the battery cover 308 may be part of the clip 302.

(33) LED 312, as noted previously, may be a dim LED, a red LED, infrared and so on.

(34) Switch 318 may control operation of the LED 312. Switch 318 may have a first on position and a second off position (in the first position electricity may flow and activate the LED 312, in the second position there is no circuit formed). In addition, LED 312 and switch 318 may be of complex construction and type with multiple options for operation: different colors, timed illumination, blinking patterns, and especially different intensities of light.

(35) Knurled grip 316 is also seen.

(36) FIG. 4 is a cross-sectional side view of an alternative embodiment socket showing an embedded LED and wiring. It may be seen that the socket has been formed around the LED, which is permanently encased in the socket material, which may in some embodiments be transparent.

(37) FIG. 5 is a different side view of another alternative embodiment socket showing the hole through which an LED might be inserted during manufacture.

(38) Hole for LED 522 allows the LED to be placed without having the socket formed around it.

(39) FIG. 6 is an end view in partial transparency showing an alternative socket end on with the LED visible at the bottom.

(40) Hex drive socket 606 has LED 612 visible through the transparent material of the socket.

(41) FIG. 7 is a side view of yet another alternative embodiment socket showing a groove or channel through which an LED might be inserted during manufacture, in contrast to FIG. 5 or FIG. 4.

(42) Channel for LED 722 allows the LED to be in place and then the socket to be inserted atop it, further aiding manufacture.

(43) FIG. 8 is a side view of a hex bit tool head, showing a fine tip screwdriver head on a multi-sided base.

(44) Hex drive 814 has a hex base for socket 826. Equivalently, the base may be octagonal, square, and so forth.

(45) Numerous types of bits may be used as well, for other purposes, though carrying a large number into the field is not as easy as carrying a single bit in the hex cap itself.

(46) FIG. 9 is a simple wiring diagram showing how the device may be implemented so as to provide low light assistance. LED 912 is electrically connected on one side to switch 918, which in turn has an electrical connection to battery 924. Battery 924 is then connected to the other side of LED 912, completing a circuit. While the operative electrical connection may be direct from component to component, it is anticipated that it may also be wires. Note that the components shown are not exclusive: the device may have multiple coin batteries instead of one, multiple LEDs, complex control switches, electrical components of entirely different functions and so forth.

(47) FIG. 11 is a cross-sectional side view of another embodiment of the invention, similar to the second embodiment, with a magnet 1128 in the end of the transparent/translucent material of the drive socket 1106.

(48) Pen P may be seen but is not necessary to understanding this embodiment. In this case the hex drive socket 1106 may be seen to be a translucent material, or even a transparent material (this will depend upon the characteristics of the LED illumination, the desired level of brightness of the embodiment, etc.). In fact, in the previous embodiment shown in FIG. 3 the material may be translucent/transparent.

(49) Light source 1112 thus shines upward even though a hex bit (not shown here) is in the socket, blocking the light. Magnet 1128 also blocks the light. However, the light source 1112 nonetheless creates a loom of light at the end because it may shine around the magnet and bit, the light beams traveling through the material itself.

(50) Testing has revealed that the device may actually be printed in harder polymers and successfully function. In addition to the manufacturing advantage this provides, it may also remove the need for transporting the device to remote areas if a data connection and 3D printer are locally available. The device may also be fashioned of molded plastic, and can further be machined or formed from metal.
