The present invention relates, in general, to the field of aiming devices. More particularly, it concerns a light assembly of pre-defined shape, for removable attachment to a guide provided on a weapon.
BACKGROUND OF THE INVENTIONIn the field of weapons, one major concern is proper aiming of the target of interest. In the prior art, there has been a number of aiming accessories, such as lasers, sites, flashlights or other accessories which can be mounted on firearms. Most of these accessories use various forms of locking screws, captive screws, nut and bolt clamps or other similar techniques to clamp the accessory to the weapon, as opposed to a latching mechanism which would safely lock the accessory to the weapon. Examples of such prior art accessories are given in U.S. patents or patent applications Nos. U.S. 2001/0027620 A1; U.S. 2001/0045046 A1; U.S. Pat. No. 5,555,662; U.S. Pat. No. 5,584,137; U.S. Pat. No. 5,941,489; and U.S. Pat. No. 6,565,226.
As can be appreciated, the just-mentioned aiming accessories present a number of caveats. Accordingly, such accessories can not be readily mounted on and detached from the weapon. In most cases, such mounting and detaching require the use of specific tools, or of both hands. Therefore, the weapon user can not simply grip the aiming device with one hand and readily mount it on his weapon in order to proceed to a precise triggering.
Other related prior art documents also present significantly different types of attachment methods to weapons or involve weapons that do not have a standard rail which can be interfaced with aiming accessories. Examples of such prior art accessories are given in U.S. patents nos. U.S. 2002/0007581 A1; U.S. 2002/0100204 A1; U.S. Pat. No. 4,707,772; U.S. Pat. No. 4,777,754; U.S. Pat. No. 5,040,322; U.S. Pat. No. 5,727,346; U.S. Pat. No. 5,816,683; U.S. Pat. No. 5,822,905; U.S. Pat. No. 6,318,014; and U.S. Pat. No. 6,574,901. The problem of such prior art devices is again the cumbersome mounting process as well as the bulkiness of such devices. More specifically, if the accessories can not be readily mounted on the weapon, they have to be provided with their specific mounting device thus decreasing the motility of the weapon user on site.
Also known in the prior art is a clamping mechanism for attaching an auxiliary apparatus to the frame of a weapon, which is further characterized in that the actual attachment or removal of the apparatus can be accomplished by a user with one hand, without using separate brackets or other mechanical components. These elements are disclosed in U.S. Pat. No. 5,430,967 (Woodman et al.).
It is thus apparent, from the above-mentioned prior art documents, there is a lack for an aiming device which can be readily mounted on a weapon and be readily used separately, as an independent light assembly.
SUMMARY OF THE INVENTIONAn object of the present invention is to provide an aiming device, more particularly a light assembly, which satisfies the above-mentioned needs. More specifically, an object of the present invention is to provide a light assembly to be readily mounted on a weapon and be readily removed there from while resuming its original pre-defined shape, in order to be usable as a separate entity.
In accordance with the present invention, this object is achieved with a light assembly having a pre-defined shape, for removable attachment to a guide provided on a weapon. The light assembly comprises a housing, provided with a reflector having a lamp at one end thereof and batteries for powering the lamp through a switch. The housing of the light assembly has a pair of lateral members which can both be moved between a retracted position and an extended position. When the lateral members are in the retracted position, the light assembly has the above-mentioned pre-defined shape. When the lateral members are in the extended position, these members are adapted to engage the guide provided on the weapon. Preferably, each one of the lateral members is provided with a longitudinal groove which is shaped and sized to slidably engage a corresponding flange on the guide.
The housing of the light assembly of the present invention further has means for preventing longitudinal movement of the light assembly on the guide. According to a preferred embodiment of the present invention, the guide is provided with a plurality of cross-slots and each one of the lateral members further includes a latch having an upper portion and a lower portion. The upper portion and the lower portion of the latch each has an inner face adjacent to the side of the housing and an outer face. The latch also has a latch projection projecting inwardly from the inner face of the lower portion of the latch, for engaging any one of the above-mentioned cross-slots. The latch is pivotable between an operative and an inoperative position so that when the latch is in the operative position, it is normally inwardly biased, with the latch projection protruding into the side of the housing, thus providing the means for preventing longitudinal movement of the light assembly on the guide. When the latch is in the inoperative position, the upper portion is pivoted inwardly toward the housing while the lower portion is pivoted outwardly away from the housing, thereby preventing the latch projection from engaging the cross-slots.
According to further aspects, the present invention provides a method for removably attaching the light assembly as defined above, to a guide provided on a weapon.
The method for removably attaching the light assembly, as defined above, to a guide provided on a weapon comprises the steps of: a) providing a light assembly as described above; b) extending the lateral members until they are in the extended position; c) engaging the longitudinal grooves of the lateral members into the flanges of the guide; d) moving and maintaining the latches in their inoperative position, while sliding the light assembly on the guide; and e) moving the latches in their operative position.
Preferably, the method further comprises the following steps: f) moving and maintaining the latches in their inoperative position, while sliding the lateral members until they are in the retracted position; and g) moving the latches in their operative position, so that the light assembly resumes its pre-defined shape.
As can be appreciated, the light assembly according to the invention is very versatile, as it can be mounted on any known weapon guide while still being usable as a separate entity aside from the weapon and the guide.
These and other features, objects and advantages of the present invention will be better understood upon reading the following non-restrictive description of preferred embodiments thereof, made with reference to the accompanying drawings.
