Description
Background of the Invention
The present invention relates to a holster and particularly relates to a holster for carrying a chemical tear gas projector from an equipment belt, for example, the equipment belt conventionally worn by a law enforcement officer.
Chemical tear gas projectors are frequently carried by law enforcement officers and are generally utilized by such officers to project a stream of fluid comprised of tear gas or other chemical agent at an individual or group of individuals. The chemical agent, e.g., tear gas, effectively incapacitates such individuals. As a consequence, many law enforcement agencies have adopted chemical tear gas projectors of this type as a standard piece of equipment for their personnel.
Typically, such chemical tear gas projector comprises a generally cylindrically shaped canister containing the chemical agent under pressure. A dispensing nozzle and actuator button are provided adjacent the top of the canister. To utilize the chemical tear gas projector, the officer or other individual using the projector grasps the canister in one hand, aims the nozzle in the direction of the target individual and depresses the actuator button causing the tear gas to be projected from the canister through the nozzle to the target individual in the form of a directed stream. One such chemical tear gas projector is the MK-V1 Chemical Mace tear gas projector manufactured by the Smith & Wesson Company, Springfield, Mass.
It has been found convenient for law enforcement officers to carry the chemical tear gas projector on the same belt from which other law enforcement equipment is carried, for example the officer's revolver. However, because of the unique shape of the canister containing the chemical agent, the need to releasably secure the projector in the holster in a manner providing for quick access to the projector, the desirability of utilizing a single holster for use with different size equipment belts, and the need to provide stability and rigidity to the holster and chemical tear gas projector carried thereby relative to the belt, that is, the need to prevent the combined holster and projector from pivoting or swinging movement relative to the belt, there is thus an established requirement for a new and unique holster for carrying a chemical tear gas projector from the equipment belt, for example, worn by law enforcement officers.
Summary of the Invention
It is a primary object of the present invention to provide a novel and improved holster for carrying a chemical tear gas projector.
It is another object of the present invention to provide a novel and improved holster for a chemical tear gas projector and which holster is provided with an opening adjustable to receive equipment belts of different sizes.
It is still another object of the present invention to provide a novel and improved holster for a chemical tear gas projector wherein the holster has lateral stability, that is, the holster is substantially prevented from rotating or pivotal movement relative to the portion of the equipment belt directly supporting the holster.

Description of a Preferred Embodiment
Reference will now be made in detail to the preferred embodiment of the present invention, an example of which is illustrated in the accompanying drawings.
Referring now to the drawings, particularly to FIGS. 1 and 2, there is illustrated a holster, generally designated 10, constructed in accordance with the present invention. Holster 10 is illustrated carrying a chemical tear gas projector, generally designated P. Chemical tear gas projector P is described in detail in copending application Ser. No. 697057 filed 1-31-85 and per se forms no part of the present invention. For purposes of facilitating an understanding of the present invention, however, chemical tear gas projector P comprises a generally cylindrical canister 12 having at one end an actuator button 14 accessible through an opening 16 on one side of the canister and a nozzle on the side thereof opposite access opening 16. Canister 12 is shaped along one side thereof to provide a grip for an individuals hand and a clip 18 is provided along one side and toward the opposite end of the canister from button 14. Clip 18 serves as an alternate means than a holster for carrying the projector P. Further details of the tear gas projector P may be obtained by reference to the above identified copending patent application.
It will be appreciated from a review of the drawings and the ensuing description that canister 12 is carried by holster 10 in an inverted orientation. That is, actuator button 14 is normally located at the upper end of the projector when the latter is in use. It will also be appreciated from a review of the drawings that canister 12 is generally hexagonal in cross sectional shape as illustrated in FIG. 8.
Holster 10 is preferrably of unitary construction as described in detail hereinafter and includes an elongated holster body 20 having first and second end portions 22 and 24, respectively, and an intermediate portion 26 therebetween. As best illustrated in FIG. 2, first or lower end portion 22 includes an upwardly opening receptacle 28 for receiving the inverted upper end of chemical tear gas projector P. Receptacle 28 has five discrete sides and is thus generally shaped to receive the upper hexagonal end of canister 12 as illustrated in FIG. 8. To provide a snug friction fit for the upper end of canister 12, a plurality of laterally spaced ribs 30 project into receptacle 28 from the inner side wall of first end portion 22 for engagement with adjacent sides of the hexagonal upper end of the canister, the ribs being flexible facilitating both a snug fit and ease of withdrawal of projector P from holster 10. The lower end of first end portion 22 carries the male portion 32 of a snap fastener for reasons discussed hereinafter.
The second or upper end portion 24 is thickened at 34 and carries an end tab 36. Tab 36 carries the female portion 38 of the snap fastener which similarly projects to the rear side of upper end portion 24. Tab 36 and thickened portion 34 form a flange 40 which extends the full width of second end portion 24 for reasons which will become apparent. As best illustrated in FIG. 3, the rear face of thickened portion 34 of upper end portion 24 carries first and second pairs of projections 42 and 44, respectively, and which pairs are vertically spaced one from the other. The projections of each pair thereof are laterally spaced one from the other and are located adjacent opposite lateral edges of second end portion 24. A reduced thickness portion 46 connects the thickened portion 34 and intermediate portion 26 thereby providing flexibility and enabling the second or upper end portion 24 to be bent or folded from the position illustrated in FIGS. 4-7 as described in detail hereinafter.
Intermediate portion 26 is offset outwardly from the first or lower end portion 22 as best illustrated in FIGS. 6 and 7 and is provided along its inner face with a plurality of laterally and vertically spaced openings or recesses 48 defined by ribs 49. Laterally outer openings 48 lie in registration with corresponding projections 42 and 44 respectively when the upper or second end portion is bent or folded into the position illustrated in FIGS. 4-7 as described hereinafter. Intermediate portion 26 also includes a pair of straps 50 and 52 extending respectively from opposite side edges thereof. Each strap is connected to intermediate portion 26 by a reduced thickness section which provides flexibility and facilitates bending of straps 50 and 52 about projector P as illustrated in FIG. 9. Straps 50 and 52 carry the male and female portions 54 and 56, respectively, of a snap fastener so that when the straps are engaged about projector P and secured one to the other by the snap fastener projector P is releasably retained in receptacle 28.
Preferrably, holster 10 hereof is of unitary construction. For example, holster 10 may be formed of a plastic material, such as polyurethane or some other thermoplastic elastomer. Alternatively, holster 10 may be formed of leather with discrete individual pieces being formed and secured one to the other in a manner well known but in the configuration described and illustrated.
To utilize the holster hereof, the upper or second end portion 24 is bent or folded about portion 36 into a position extending generally parallel and in opposition to the back or rear face of intermediate portion 26. The male and female portions 32 and 34, respectively, of the snap fastener are secured one to the other whereby the second or upper end portion 24 is releasably secured to the first or lower end portion 22. In this position, it will be appreciated that projections 42 and 44 register with and are received within corresponding recesses 48 as illustrated in FIG. 6. Importantly, from a review of FIG. 6, it will also be appreciated that the inner faces of thickened portion 34 of the second end portion, the ribs 49 of intermediate portion 26, the flange 40 and the edges of the first projections 42 define an opening for receiving an equipment belt B of a first predetermined size. It will further be readily appreciated that belt B can be passed or slipped through the opening thus defined or the upper or second end portion 24 can be bent or folded about the belt B to secure the holster to the belt with the belt located between the intermediate and upper end portions 26 and 20, respectively. Chemical tear gas projector B may then be inverted and its upper end disposed in receptacle 28. Straps 50 and 52 may then be engaged about the lower end of projector P and releasably secured one to the other.
It is a feature of the present invention that the holster, when secured to belt B, is stable relative to the portion of the belt passing through the opening defined between the second and intermediate portions 24 and 26, respectively. That is, means are carried by the holster body and engageable with the belt for substantially preventing rotational movement of the holster body relative to the portion of the belt passing within the holster body and thus the holster cannot swing laterally or pivot relative to the belt portion received within the holster. To achieve such stability and in a preferred embodiment of the present invention, it will be appreciated that flange 40, abutments defined by projections 42, the thickened intermediate portion 34, and the ribs 49 carried by intermediate portion 26 provide substantial rigid constraints about belt B such that the holster cannot swing about an axis perpendicular to or pivot about a lateral axis wholly within the belt portion received within the holster. The holster is thus optimally constrained against such movement. Note that projections 42 bear against the outer edges of ribs 49 which define the outermost recesses 48. This provides lateral stability, e.g. prevents relative lateral movement of the intermediate and end portions 26 and 24, respectively, in a sideways direction. Thus the holster is substantially rigidly secured to the belt and yet can also be readily released from the belt simply by unfastening the snap fastener joining the opposed end portions 22 and 24 one to the other.
It is also an important feature of the present invention that means are provided on the holster body for adjusting the size of the opening receiving the belt to enable the holster to be carried by belts of different sizes. To accomplish this, and in a preferred embodiment hereof, the belt opening between the flange 40 and first projections 42 may be enlarged to accomodate a belt of a larger size by removing the first set or pair of projections 42 from the holster body. These projections 42 may simply be cut from the second end portion by using a suitable tool. Thus, when the second end portion is bent into the position illustrated in FIG. 7, projections 44 register with and project into the uppermost recesses 48 along the rear face of intermediate portion 26 to define with flange 40 an opening of greater height or elevational extent. Consequently, to accomodate a wider belt, projections 42 are simply removed. However, the stability of the holster relative to the belt, e.g. the prevention of substantial rotational movement, both swinging and pivoting movement of the holster relative to the belt, is retained. Thus, the larger belt fits snugly into the opening defined by the opposed faces of the intermediate and second end portions 26 and 24, respectively, flange 40 and the abutments formed by projections 44 and which projections engage the holster body in the uppermost of recesses 48.
It will be apparent to those skilled in the art that various modifications could be made in the holster for chemical tear gas projector hereof without departing from the scope or spirit of the invention.
