Abstract

This sighting device is notable in that the firearm is arranged, at at least one visible point (2, 3 or 4) of the line of sight, to receive and retain at least one element (1) capable for a specific time of diffusing a concentrated light by chemiluminescent effect, making it easier to locate a target in darkness or dusk. <IMAGE>

Description

Aiming device for all types of eye-pointing shooting weapons.

The subject of the invention relates to the technical sector of sighting devices for firearms, compressed air, bows and crossbows.

There are devices and devices that facilitate nighttime or half-light aiming.

This equipment uses either radioactive lithium pellets or light-emitting diodes attached to conventional weapon aiming devices.

Radioactive lithium pellets emit light that is too weak to be effective. On the contrary, the diodes are too powerful and therefore dazzle the shooter and mask the target; on the other hand, the electrical circuit with battery and switch is bulky and incompatible with certain weapons.

According to the invention, it was desired to produce a simple, economical, and effective aiming device for precision shooting in conditions of limited illumination.

For this, and according to a first characteristic, the weapon is arranged at at least one remarkable point of the line of sight to receive and retain at least one element capable of diffusing for a determined time a light concentrated by chemiluminescent effect facilitating the location of 'a target in the dark or in the dark.

According to another characteristic, the chemiluminscent element established in the form of a transparent envelope, is engaged and retained in the appropriate orifice of a support fixed at a suitable point of the weapon situated on the line of sight; the light emitted being visible at least from the side of the shooter's eye.

Other characteristics are found in the fact that the support of the chemiluminscent element is directly integrated into the manufacture of the weapon or else composed of an independent member attached and fixed to the weapon by any removable or removable means.

These characteristics and others will emerge from the description which follows.

To fix the subject of the invention without however limiting it, in the appended drawings:

Figure 6 is a perspective view illustrating an embodiment of the sighting device according to Figure 5; the main components being shown separately.

FIG. 7 is a sectional view illustrating an exemplary embodiment of the aiming device according to FIG. 4.

In order to make the object of the invention more concrete, it is described in a nonlimiting manner illustrated in the figures of the drawings.

Tubular elements (1) made of transparent plastic are commercially available under various names having in the middle a partition (1a) delimiting two compartments (1b-1c). Each compartment contains a specific chemical solution which, when mixed by manual rupture of the partition, emits a soft, concentrated and generally colored fluorescent type light. This light has a lifespan of a few hours and can be used to illuminate a limited area.

According to the invention, it has been thought to apply this chemical property to constitute a device for assisting aiming on weapons of all types such as firearms, bows, crossbows, in the case of shooting in a poorly lit environment, or even obscure.

For this, and as illustrated diagrammatically in FIGS. 2 and 3, there are in any conventional manner one or more chemiluminescent elements (1) on or in one or more supports (2), (3), (4) secured to weapons ( 5), (6) ..

For example, as shown in Figures 2 and 4, there is an element (1) at the end of the barrel of a rifle or rifle (5) in place of the handlebars or in addition to the handlebars. There is thus obtained, after the element (1) has been put into service by mixing the chemicals, a bright spot facilitating aiming in the dark or in the dark.

For other weapons such as handguns (6), or for rifles and shotguns, there are in addition to the handlebar light device, two other chemiluminescent devices (3, 4) from the barrel, for example at level of the traditional rise. The two light points are spaced transversely so that when aiming, the axial light point (2) is obtained from the handlebars, a precise location of the target by three light points placed side by side (Figures 3 and 5).

The implementation of this aiming device at one or more light points can be achieved in different ways. We have illustrated only by way of example two embodiments in FIGS. 6 and 7.

In Figure 6, there is illustrated a device with three light points obtained by three chemiluminescent elements (1) which are associated with suitable supports, namely for the handlebar light point, the element (1) is slidably inserted into the longitudinal orifice (7a) of an elongated block (7) which can be formed directly at the end of the barrel or attached and fixed by any removable or removable means to the barrel of the weapon.

For the light points of the rise, the elements (1) are slidably inserted into spaced sheaths (8) associated with a transverse board (9) with a central notch (9a) revealing the light point of the handlebars. This assembly is either directly formed by the rise, or attached and fixed by any removable or removable means allowing transverse adjustment.

In Figure 7, there is illustrated a light handlebar device which comprises a sole (10) for fixing to the barrel or other member of the weapon (ventilated strip, sight, breech ...); this fixing taking place by any means such as screwing, riveting, gluing, clipping ... The sole carries a member for housing the chemiluminescent element (1), for example a hollow and shouldered sleeve (11) open on both sides and into which is inserted the element (1) which can be retained there on one side in abutment against the rear wall (11a) of the sleeve and on the other side by a cap (12) engaged on the thinned part of the muff ; said cap being able to be itself retained by a raised cutout (10a) of the sole.

Other specific embodiments and arrangements can be provided within the framework of the invention. For example, the support or supports for the elements (1) may have a notch making it possible to break the partition (1a) of the element (1) when it is in place. The element (1) can be retained in its housing by a hard point (pin, tangent, projection ...), by elasticity, by clipping, by plug .... The element (1) housing can be open on both sides or only on the side of the shooter's eye. The face of the support on the side of the shooter's eye may be of a different color from that of the element (1). The integrated or attached support (s) can be made of any material (metal, plastic, wood, etc.) The elements (1) can be of any shape (tubular, spherical, polygonal, etc.)

• Le repérage précis d'une cible fixe ou mobile dans l'obscurité ou la pénombre par le ou les points chimiluminescents à durée d'éclairement importants.
• L'adaptation rapide et aisée des éléments chimiluminescents sur leurs supports.
• L'équipement possible de toutes armes sans modification particulière.
• Le prix de revient intéressant de ce dispositif utilisant des éléments chimiluminescents standards.

The advantages clearly emerge from the description, it is emphasized in particular:

• The precise location of a fixed or mobile target in the dark or half-light by the chemiluminescent point (s) with significant lighting duration.
• Quick and easy adaptation of the chemiluminescent elements on their supports.
• The possible equipment of all weapons without particular modification.
