Patent Application
20220090880
The present invention relates to actuation devices for activating a tactical flashlight, i.e. a flashlight that can be mounted to a firearm, in particular a long-barreled firearm such as a rifle or shotgun.
Flashlights are commonly mounted on military and law enforcement weapons to aid in accurate target identification during low-light conditions by providing the ability to accurately identify and target subjects before engaging them. Because low-light target identification is critical for the safety of police, military, and other firearm users, a weapon-mounted light needs to be easily located and activated.
Tube-body flashlights are commonly mounted on weapons to provide illumination and are mounted parallel to the barrel of the weapon. Long-gun-mounted, tube-body flashlights are commonly activated by pushing an end cap or tail cap button, located on the end of the flashlight's body. The factory placement of the activation button on the end of the flashlight's tailcap, however, is non-ergonomic, or awkward to activate when mounted to a long-gun, because the means of activation requires forward motion of the user's thumb, of which, the same hand is grasping the weapon.
A common solution which makes activation of a tube-body weapon-mounted flashlight more natural and ergonomic, is to replace the flashlight's original button tailcap with a switch that is wired to the flashlight. The switch may be placed in a more ergonomic location on the long-gun. The relocation of the flashlight's activation switch allows the flashlight to be activated by a more ergonomic lateral squeeze motion. There are three problems, however, with the common practice of replacing a flashlight's original button tailcap with a remotely wired switch:
Problem 1: The wires connecting the remote activation switch to the flashlight, can easily be damaged from various things, such as heat, impact, kinking, abrasion and snagging.
Problem 2: If the remotely wired activation switch is damaged, there is no secondary method to activate the light because original button has been replaced.
Problem 3: Some remotely wired tape switches, when installed in place of a flashlight's original tailcap, do not perform all of the functionality that was originally available by way of using the factory-supplied button tailcap.
Accordingly, there is a need for a reliable, non-electronic/electric, mechanical way to activate a tube-body, weapon-mounted flashlight, that offers a less-awkward, more ergonomic actuation method.
The various embodiments of the present invention may, but do not necessarily, achieve one or more of the following advantages:
the ability to mechanically activate a tailcap switch of a light;
the ability to use lateral pressure to activate a tailcap switch of a light;
the ability to operate a tailcap switch of a light mounted to a firearm while maintaining grip on the firearm;
the ability to operate a tailcap switch of a light by squeeze pressure;
the ability to move an external tailcap button actuator to an ineffective or stored position to enable standard operation of a tailcap button of a flashlight;
the ability to safely store an external tailcap button actuator so that it cannot inadvertently actuate the tailcap button.
These and other advantages may be realized by reference to the remaining portions of the specification, claims, and abstract.
In one aspect of the present invention, a mechanical apparatus is provided that attaches to a tubular-bodied, long-gun-mounted flashlight that affords a user the ability to activate the flashlight's tailcap button. The mechanical apparatus may comprise a clamp body for securing the mechanical apparatus to the flashlight and a paddle lever pivotally mounted to the clamp body. The paddle lever is rotatable from an effective position that in use, enables a user to press the paddle lever against the tailcap button to actuate the tailcap button, and a storage position located away from the tailcap button.
In one aspect of the present invention, there is provided a mechanical apparatus that attaches to a tubular-bodied, long-gun-mounted flashlight which affords a user, the ability to activate the flashlight's tailcap button. The mechanical apparatus may comprise clamp body means for securing the mechanical apparatus to the flashlight, and paddle lever means pivotally mounted to the clamp body means for actuating the tailcap button. The paddle lever means may comprise rotation means for rotating the paddle lever means from an effective position that in use, enables a user to press the paddle lever means against the tailcap button to actuate the tailcap button, and a storage position located away from the tailcap button.
The above description sets forth, rather broadly, a summary of one embodiment of the present invention so that the detailed description that follows may be better understood and contributions of the present invention to the art may be better appreciated. Some of the embodiments of the present invention may not include all of the features or characteristics listed in the above summary. There are, of course, additional features of the invention that will be described below and will form the subject matter of claims. In this respect, before explaining at least one preferred embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of the construction and to the arrangement of the components set forth in the following description or as illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part of this application. The drawings show, by way of illustration, specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.
In the present Applicant's co-pending patent application Ser. No. 16/100,140, the entire contents of which are incorporated herein by reference, there is described a mechanical lever that clamps onto the tail cap of a tube-body flashlight and activates the flashlight's tail cap button by squeezing or pressing a lever in an ergonomic direction perpendicular to a longitudinal axis of a body of the flashlight.
As was described in the Applicant's co-pending patent application referenced above, the tail clamp includes stoppage surfaces for limiting the range of rotation of the lever clamp so that the lever is always maintained in substantial contact with the tail cap button.
It has been found that limiting the range of rotation can have disadvantages. For example, when storing the firearm with the light and lever clamp in place, the lever may lean against firearms or other devices that inadvertently cause the lever to actuate the tail cap button, causing the batteries of the light to discharge. A further disadvantage is that if the lever clamp fails, the lever cannot be moved sufficiently to provide access to the tail cap button without having to remove the complete clamp assembly. A further disadvantage is that because the lever clamp is simple to operate, requiring only light pressure to actuate the tailcap button, there can be times when the light is inadvertently turned on or turned off, which may create issues in a tactical or operative environment. To overcome or at least ameliorate these disadvantages, an alternative embodiment will be describe herein.
A lever clamp 100 is shown in
A paddle lever 120 attaches to the clamp element at a hinge joint 130 located at a back edge of one of the clamp body components 112114. In the embodiment depicted, the paddle lever 120 attaches to the upper clamp body 112. The paddle lever is able to move through a range of motion from an effective position (
The paddle lever 120 is an angled component having a short hinge extension 121 that extends from the hinge joint 130, a first portion 122 that extends from the hinge extension 121 and, in use in the effective position, lies against the tailcap button of the flashlight. At an end of the first portion 122 opposite the hinge joint end, a second portion 124 extends from the end of the first portion 122 at an angle that is both outward, i.e. backward in the normal orientation of the lever clamp, and further away from the hinge joint 130 (downward in the orientation depicted). A third portion 126 extends from an end of the angle second portion. The third portion, in use in an effective position, lies in a plane that is parallel with the longitudinal axis of the flashlight body. An end of the third portion 126 may include a rounded section 127 that partially defines a cradle with the third portion and second portion so that a user may comfortable locate and nestle a finger or thumb on the paddle lever.
On the forward side of the paddle lever 120, adjacent a junction of the first portion 122 and second portion 124, is a rounded protrusion 128 extending along the width of the paddle lever 120. The protrusion 128 provides a hammer or similar contact point for contacting the tailcap button of the flashlight.
The paddle hinge joint 130 is located at a rearward edge of the clamp body 112.
The hinge joint 130 comprises two outer hinge elements 132 that extend backward, relative to the longitudinal direction of the flashlight body when the lever clamp is in use, of the upper clamp component 112. The paddle lever 120 includes a central hinge element 134 that is received between the outer hinge elements 132. A hinge pin 136 passing through all of the hinge elements 132, 134 secures the hinge 130. The paddle lever 120 is thus able to pivot on the hinge pin 136 to sweep through a rotational range of motion. The lever clamp 100 is shown attached to the body 162 of a flashlight 160 in
In one embodiment, the paddle hinge 130 allows the paddle lever 120 to rotate from the effective position through at least 180 degrees. In one embodiment, the paddle lever is rotatable through approximately 270 degrees so that the paddle lever 120 rests against an outer surface of the clamp body. In one embodiment the first clamp component has a longitudinal ridge or rib 142 disposed in alignment with the gap between the two outer hinge elements 132. The paddle lever 120 has a corresponding channel 144 in the rearward outer surface, e.g. in the hinge extension 121. As the paddle lever 120 is rotated from the effective position to the storage position, the rib 142 is accommodated within the channel 144. Additional retention mechanisms, such as clips or retention ridges may be provided so that the paddle lever 120 can be maintained in the storage position and will not inadvertently return to the effective position, e.g. whilst the firearm is being transported.
The paddle lever hinge 130 is located on the rearward edge of the clamp body so that, in use, the lever hinge is located to a lateral side of the tailcap body (i.e., to the left, right, above, or below) rather than being immediately behind the tailcap button in the longitudinal direction. In the particular embodiments depicted, the lever hinge 130 is located above the tailcap body 166. The paddle lever extends from this hinge across the tail cap button to the rounded portion 127 at the distal end of the third portion 126 of the paddle lever 120. By having the hinge 130 located to the side of the tailcap button and having the paddle lever 120 extend across the tailcap button, substantial leverage can be created by the user applying lateral pressure on the paddle lever, e.g. at the third portion which is approximately perpendicular to the first portion and to the tailcap button.
By allowing the paddle lever to be rotated from the effective position into a storage position, several additional benefits may be achieved. In the storage position, the light switch will not be easily inadvertently toggled while the firearm is stored.
There may also be reasons to prevent toggling of the light switch during use. For example, if the light is off, the user may wish to avoid toggling the light on and risk revealing the user's position. Alternatively, the light may be on and the user may not wish to risk the light toggling off while the user is attempting to shoot. The full range of the paddle lever 120 allows the user to select whether the paddle lever is located in its effective position or in a storage position which cannot affect the button 164.
The user can also move the paddle lever 120 out of its effective position in the event of some failure so that the user can readily access the tailcap button of the flashlight in its standard manner.
The configuration of the paddle lever, allowing lateral pressure to be used to actuate the tailcap button, allows the flashlight to be mounted and actuated in a range of positions on the firearm, depending on the user's ergonomic preference. The flashlight may be mounted on the top, underneath, left or right of the firearm. In any of these positions, the paddle lever may be accessible to the user.
Although the description above contains many specifications, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the embodiments of this invention. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents rather than by the examples given.
