Nail gun reload indicator

Abstract

The “nail gun reload indicator” gives the user an alarm when his/her nail supply is near depletion. The indicator beeps and a light comes on to make the user aware of the need to replenish his/her nail supply, thus creating a more effective product with the nail gun of choice. The invention will encompass the idea of alerting the user of a nail gun of near depletion of nails as indicated by any source as technology may advance to allow ease of use. This invention provides an improvement to an existing product, a standard nail gun. The improvement is an attachment or can be placed inside the standard nail gun and allows an alarm to sound, indicating when the supply of nails is almost depleted. Therefore, allowing a supply of nails into the nail gun, instead of haphazardly firing, until there are no more nails. The invention of the “nail gun reload indicator” is explained therein to provide a simple understanding of said invention, but is should be noted that this idea applies to any such variety of any device that may achieve the same end result. Let it be noted that for the purposes of this application, the term “nail gun” will apply to all fasteners, staplers and trim guns.

Description

The following describes, briefly, the action involved in making the “nail gun reload indicator” successful in and of itself. There are many nail fasteners and staplers on the market today. While each brand differs in design, the basic principle for holding and advancing a fastener into the firing sleeve, via a constant force spring, is the same.

These principle parts consists of a magazine (to hold the fastener) FIG. 1(A) and a constant force spring (B), for maintaining constant forward tension on a fastener supply and advancing nails into the firing sleeve (C). Where upon pulling the actuator or trigger of a nail gun, a burst of air is released, driving a piston down on to the nail that is positioned in the firing sleeve (C). Thus, forcing the nail into the desired material. The constant force spring (B) is a coiled band of steel attached to the exit end of the magazine (A). Attached to the opposite end of this band is a pusher (D) (not shown) which presses nails forward and is pulled back manually with a pusher handle (E) into a locking position. Nails are then loaded into a magazine (A). This pusher is then released where forward tension is maintained advancing fasteners into their firing position.

The pusher is attached internally in the magazine to the constant force spring (B) (not shown). The pusher handle is attached externally of the magazine to the pusher.

The constant force spring forces nails forward into the magazine as they are expended. The constant force spring returns to it's coiled position at the exit end of the magazine bringing the attached pusher and pusher handle to the exit end of the magazine.

The forward advancement of the pusher handle (common to all fasteners) is the triggering mechanism for the alarm on the reload indicator. The pusher handle moves forward as nails are expended, bringing it into contact with a rigidly mounted compact mini switch, which will cause an alarm to sound as the nail source is depleted or through an adjustment in the push button's plunger, nearly depleted.

For purposes of explaining the components of the nail gun reload indicator, refer to FIG. 2 (1-5). The nail gun reload indicator, consists of a casing (1), push button switch (2), L.E.D. (3), battery and holder (4) and a buzzer (5).

The casing (1), consists of a compact housing agent for holding all of the components of the nail gun reload indicator in place.

The push button switch (2), is the device that triggers the alarm on the nail gun reload indicator.

The L.E.D. (3), consists of a light to alert the user of a nail gun of nail depletion. The light emitting diode (L.E.D) is a bright light that should be easily seen by the nail gun user.

The battery and holder (4), is used to power the nail gun reload indicator. This concept drawing shows a 12-volt battery, but the invention is not limited to using this type of power.

The buzzer (5), is a device of alarming the user of the nail gun reload indicator, of nail depletion. The sound should be loud enough to be heard under loud construction conditions.

For purposes of explaining the push button, in detail, refer to FIG. 3 (1-7) and for the adjustable plunger, FIG. 4 (1-2). The push button on the nail gun reload indicator consists of a plunger extension with mail thread (1), plunger with female thread (2), fastening nut with a lock washer (3), contact band (4), contact (5), spring (6) and switch casing (7). The switch plunger (2) is located beyond the maximum forward position of the pusher handle (1). From this point, the plunger extension can be adjusted, as to allow the plunger to travel through the body of the switch. This will eliminate damage to the switch, in case of sudden release of the constant force spring (6).

For purposes of describing the embodiments of the bracket for mounting the nail gun reload indicator, refer to FIG. 5.

For purposes of describing the nail gun reload indicator, as mounted to nail gun, refer to FIG. 1. This picture show the nail gun reload indicator mounted to the Paslode™ nail gun.
