The invention relates to a holster assembly for a handgun, and more particularly to such a holster with a retention assembly for preventing unauthorized access to a handgun and more particularly constructed with injection molded, reinforced plastic inserts that are injection over-molded with a chemically compatible material which provides the desired surface characteristics of the holster.
Handgun users, and particularly Law Enforcement personnel who carry a handgun on a daily basis, carry the handgun in a holster. It is important that the holster provide for a safe quick draw of the handgun and that the handgun be secured in the holster until the authorized user purposely withdraws the handgun. The handgun must be secured so as not to inadvertently fall out of the holster and most importantly secured against being removed from the holster by an adversary.
Prior art describes various holster assemblies designed to address these issues. Prior art is shown in Bianchi U.S. Pat. No. 4,101,060; Rogers U.S. Pat. No. 4,694,890, Rogers U.S. Pat. No. 4,925,075, Rogers U.S. Pat. No. 5,275,317; Rogers U.S. Pat. No. 5,501,381; Nichols U.S. Pat. No. 5,284,281; Salandre U.S. Pat. No. 4,934,574; Marx U.S. Pat. No. 5,419,474; and Beletsky U.S. Pat. No. 5,199,620, The present invention is an improvement over these prior art holsters.
An improved holster assembly is accomplished by utilizing a trigger guard securing mechanism as described in the inventor's U.S. patent application Ser. No. 09/382,113 with the further addition of secondary securing features and locking mechanisms that prevent the trigger guard securing mechanism from being released until a deliberate motion is completed by the user.
Improved surface characteristics are accomplished utilizing modern thermoplastic material and high-pressure injection molding techniques. The present invention is based upon the discovery that a holster assembly comprising inserts of reinforced thermoplastic material, with over-molded thermoplastic material which determines the characteristics of the outer surfaces of the holster, can produce an economical aesthetically pleasing holster. There are six Shore scales that are used to measure the hardness of synthetic materials. They are as follows: Shore A, Shore B, Shore C, Shore D, Shore DO and Shore OO. All of the scales range from 0-100, The most commonly used scales are Shore A and Shore D. There is no direct conversion between the different scales. An example of an approximate comparison would be (Shore A 50=Shore B 30-35=Shore C 20=Shore D 10-15). Another example of approximate comparison would be (Shore A 100=Shore B 85=Shore C 65=Shore D 45). The preferred material used for the insert has a hardness of approximately Shore D 70, When a thermoplastic elastomeric material with a Shore A durometer of 90 or below is used as the over-mold material, the selected holster parts are provided with a soft but durable surface which can be molded with unique and complex characteristics. The thermoplastic elastomeric material should not have a durometer hardness greater than Shore D50, Some synthetic materials have a durometer hardness that would be measured on the Shore A scale. Harder synthetic materials would be measured on the Shore D scale.
The elastomer thermoplastic material provides a completely different and arguably superior holster finish as compared to conventional holsters. The surface provides an aesthetically pleasing finish which can be made in many colors. While not intending to be so limited, the invention will be described in its application to a handgun holster. It will be understood that the basic teachings of the present invention can be applied to other types of holsters.
It is an object of the present invention to provide an improved handgun holster.
It is also an object of the present invention to provide an improved holster with novel structure for securing the handgun from being withdrawn from the holster until the authorized user intends to do so.
It is another object of the present invention to provide an improved holster with novel structure for securing the handgun that requires a difficult and unnatural motion for anyone except the authorized user thereby minimizing the possibility of an unauthorized assailant withdrawing the handgun.
It is an additional object of the present invention to provide an improved holster with novel structure for securing the handgun that allows the authorized user to quickly and naturally withdraw the handgun in a safe manner.
It is a further object of the present invention to provide an improved holster with novel structure for securing the handgun that allows for remote operation of the securing mechanism.
It is also an object of the present invention to provide an improved holster with novel structure for securing the handgun that allows for positive identification of the user before the handgun can be withdrawn.
It is another object of the present invention to provide for unique soft to the touch thermoplastic elastomer surface characteristics on the holster.
Finally, it is an object of the present invention to provide a holster assembly with the above features which is also both strong and durable.
According to the invention there is provided an improved holster having a retention device which secures the handgun from being withdrawn from the holster until the retention device has been released. The retention device must first be unlocked by a deliberate motion of the user. A holster according to the invention is constructed with an assembly which includes a pocket for receiving a handgun and the pocket has a recess for accepting the trigger guard of the handgun. The pocket has outer and inner sides and is generally “U-shaped” in such a fashion as to cover the handgun. The pocket is assembled using components that incorporate interior supporting structures referred to as inserts which are molded of a reinforced thermoplastic material. The inserts are over-molded with a thermoplastic material which provides them with the desired surface characteristics. The inserts are precisely dimensioned so that their areas to be over-molded are smaller than the finished component. The inserts are designed to give maximum strength to the holster and are shaped to promote the flow of the over-mold material. When the thermoplastic material of the inserts and the over-mold elastomer material are both of the same chemical base, the over-mold layer will bond both mechanically and chemically with the inserts and will provide the holster with soft, but durable aesthetically pleasing surfaces. These surfaces may be smooth or textured to enhance the feel and appearance of the holster.
The retention assembly structure is located in the recess designed for accepting the handgun trigger guard and comprises a movable pin that positively captures the trigger guard. The movable pin is preferably spring loaded in the direction of capturing the trigger guard and is further beveled towards the receiving aperture of the trigger guard recess. The moveable pin in this configuration contacts a spring loaded catch that moves out of the way when the gun is inserted and the moveable pin subsequently engages the trigger guard to secure the handgun. The end of the pin opposite its retaining end is provided with structure that engages a fork shaped actuating wedge. The actuating wedge is moveable perpendicular to the centerline of the retention pin. To release the handgun the moveable retention pin is pulled from the trigger guard recess by pushing the actuating wedge in a perpendicular plane to the centerline of the retention pin. This motion slides the wedge in such a manner as to pull open the retention pin by the nature of the wedge shape. The actuating wedge is spring loaded to return to its resting position, which, in turn, returns the retaining pin to its locked position. The engagement between the retention pin and actuating wedge is such that the retention pin can move independently of the actuating wedge and upon re-holstering the handgun trigger guard pushes the pin against its spring tension allowing the pin to move out of the way followed by returning to capture the trigger guard when the trigger guard is fully inserted into the trigger guard recess.
To provide the holster with the desired level of security the actuating wedge cannot be pushed without purposely moving a locking slide. The locking slide is moveable perpendicular to the motion of the actuating wedge and is provided with structure that locks the actuating wedge until the locking slide is moved into its unlocked position. The locking slide can further be provided with a secondary locking structure such as a pin that engages with the locking slide or the actuating wedge. The secondary lock can be remotely unlocked pneumatically, electrically or by any other suitable means. The locking mechanism of the holster can also be provided with features that positively identify the authorized user of the holster, such as a Biometric finger print reader, a coded magnetic ring, etc.
To further enhance the security of the holster the present invention can be provided with a safety strap spanning the open end of the holster capturing the handgun until the strap is opened or moved out of the way. In the preferred embodiment both ends of the strap are pivotally fastened to opposite sides of the holster. The safety strap is pivotable from the first security position, which inhibits removal of the handgun from said holster, to a second position substantially free of the handgun, allowing the handgun to be withdrawn from the holster. The safety strap is pivoted by the motion of the actuating wedge through a mechanical linkage. The safety strap can also be of a more conventional style having both ends fastened to opposite sides of said holster by snap members. Utilizing a conventional snapped strap may be preferable under some conditions and because the handgun is otherwise secured by the retention pin, the handgun remains secure even if the strap becomes un-snapped. Additionally, to enhance the security of a snapped strap, the strap can be provided with a formed releasing element shaped to release the snap using a generally downward motion of the users hand.
It will be understood by one skilled in the art that, for each type or model of holster to which the present invention is to be applied, the finished holster, and components thereof must be appropriately designed in accordance with the teaching of the present invention. The exemplary holster is assembled from several components and the number, size and precise shape of the components can vary. Each holster will contain such components as required, depending on the particular handgun used in the holster and the desired security level of the holster.
The handgun holster will now be described by referring to
The primary locking mechanism 42 is supported and mounted on plate-shaped carrier member 41 as clearly shown in
Referring to
A spring 65 (seen in
Moveable retention pin 53 is moveable into and out of recess 40 which is designed for accepting the handgun trigger guard 69 (see
The end of the moveable locking pin 53 opposite its beveled retaining end is provided with a detail engaging the fingers 50 and 51 of the forked-shaped wedge 48. The detail is shown in cross sections AA-DD. Actuating wedge 48 is moveable perpendicular to the center line of the moveable retention pin 53 in a generally downward motion opposite the direction of withdrawing the handgun from the holster. The actuating wedge 48 is beveled in a wedge shape that slides over the retention pin 53. To release the handgun the moveable retention pin 53 is moved out of the trigger guard recess 40 by pushing the actuating wedge 48 downward in a perpendicular plane to the center line of the retention pin 53. As the actuating wedge 48 is pushed the wedge shape rides on the detail of the moveable retention pin 53 and the retention pin 53 is pulled free of the handgun trigger guard 69 allowing the handgun to be withdrawn from the holster body.
A holster of the present invention provided with the locking assembly as described above securely retains the handgun and the handgun can be withdrawn quickly. However, in a Law Enforcement situation an adversary could also easily withdraw the handgun. In the preferred embodiment the holster of the present invention is further equipped with a locking slide 71 (see
Safety strap assembly 44 (see FIGS. 1 and 13-14) is included to further enhance the security of the holster of the present invention by capturing the handgun around the top opening of the holster. The safety strap assembly 44 of the preferred embodiment spans the top end of the holster and captures the handgun until the strap is pivoted out of the way. Both ends of strap 84 are fastened to the holster by stub axles or pins 85 and 86. Safety strap 84 is U-shaped and made of hard plastic. Stub axle or compressible pin 85 has a pair of spring fingers that pop into a bore hole 88 formed in a tubular bushing portion 90 on the top end of interior side wall 36. Safety strap 84 is pivoted forward and into the open position shown in
The exemplary holster body is assembled from several components. The number, size and precise shape of the components depend on the particular handgun the holster is designed for and the desired security level of the holster. In the example embodiment the holster body is comprised of spacer plates or panels 38 and side walls 34 and 36 of

Inserts 104 and 105 are preferably molded of a strong, reinforced, synthetic material. Any appropriate synthetic material can be used as long as it is chemically compatible with the over-molded material. The synthetic material of the inserts may include a reinforcing filler material. Some examples of a reinforced material are: 1) a fiberglass reinforced, olefin base, thermoplastic material, 2) a fiberglass reinforced, nylon material 3) a fiberglass reinforced polypropylene material. When the preferred thermoplastic elastomer TPE over-mold is used as is described hereinafter, an olefin base thermoplastic material is necessary for the insert because, under these circumstances, the over-mold material will chemically bond with the insert material. When the injection molded insert comprises an olefin thermoplastic, the over-mold layer may comprise an olefin base thermoplastic elastomer that chemically bonds to the injection molded insert. When the injection molded insert comprises a fiberglass reinforced polypropylene, the over-mold layer must comprise an olefin base thermoplastic elastomer so as to chemically bond to the injection molded insert. Excellent results have been achieved, for example, when specific formulations of polypropylene are used as the base reinforcing insert. Any suitable materials can be used as long as the insert and over mold material are chemically compatible. An ideal material is a Homopolymer polypropylene that provides excellent adhesion to compatible olefin elastomers as well as a high resistance to abnormal sinks and flow lines. This material, once cured, has a great scratch resistance and a higher flexural modulus than co-polymer polypropylene. An example of such material is manufactured by DSM Engineering Plastics of Stoney Creek, Ontario, Canada and is identified as product code J60-30.
The inserts are designed to give maximum strength to the finished holster body. In addition, the inserts may be cored out in critical thick areas to reduce warping, excessive swelling or other deformation of the insert.
Each insert is precisely dimensioned so that its areas to be over-molded are smaller than the finished holster body. The dimensions are chosen to minimize warpage of the insert and to allow for proper flow and bonding of insert material over the insert and for proper over-molding material flow and bonding.
Once inserts (or insert) 104 and 105 are molded, the next step is to mount the inserts in final molds and injection mold (over-mold under heat and pressure) thereon the thermoplastic elastomer 112 seen in
Reference is now made to
It will be understood that distortion considerations due to shrinkage, warpage, outside forces and the like are unique with respect to each over-molded holster. The inserts 104 and 105 are first molded at which point minimal shrinkage or warpage may occur and thereafter the insert components become stabilized.
Next, the over-molding places a new thermoplastic material over the already stabilized inserts creating stresses not found in single stage molded parts, When the over-mold material is applied to the inserts with the appropriate heat and pressure, and then allowed to cool and stabilize, shrinkage of the thermoplastic rubber will tend to warp certain areas of the holster body. The insert elements must be designed to minimize this warpage and to minimize the disturbance of the flow of the thermoplastic elastomer. At the same time, the flow path of the elastomer in the mold must be carefully designed to provide the most efficient elastomer-to-insert bonding.
Insert sections 104 and 105 are also designed to provide a mechanical bond, wherever possible, between the thermoplastic rubber over mold 112 and the insert. In areas where delamination would be most likely to occur, such as at thin fleeting edges of the insert, the insert is configured to cause the thermoplastic rubber to hook thereabout, forming a permanent melt seal. Such permanent melt seals are indicated generally at 120 in
It is within the scope of the invention to provide selected portions of the surface of the over-molded thermoplastic elastomer with a appearance-enhancing texture. The texture may be of any appropriate and well known type as shown generally at 120 in
Modifications may be made in the invention without departing from the spirit of it. For example, the teachings of the present invention are also applicable to holsters without a safety strap.
