Dummy Ammo

This application is a continuation of U.S. patent application Ser. No. 18/643,478, filed Apr. 23 2024, which is incorporated herein by reference in its entirety, together with its amendments.

The present invention relates to the field of training ammos, in particular to a dummy ammo.

Training ammo is a kind of ammunition that can't be filled with gunpowder or explosives. It is usually used in the training of ammunition loading and unloading, shooting feel and muscle memory to simulate the action effect needed in actual shooting. The training ammo not only has the appearance and weight close to the live ammo, but also does not cause explosion or injury when it is launched, therefore it has high safety, which can help users to be familiar with the use method and shooting skills of weapons and improve their actual combat ability.

A patent document with a publication number of U.S. Pat. No. 6,223,657B1 discloses a simulated ammunition device, which comprises a first part with a longitudinal axis and a blind hole arranged therein at a position coaxial with the longitudinal axis of the first part; the second part has a longitudinal axis, a generally cylindrical head including a circumferential edge and a stud extending coaxially with the longitudinal axis of the second part, and the stud is received by the blind hole of the first part; and a structure for retaining the stud in the blind hole.

This simulated ammunition has simple structure and firm connection, but the two parts of this simulated ammunition are made of different materials, the first part is made of plastic material, and the second part is made of metal material, which makes the center of gravity of the simulated ammunition backward, so it will have a different feel from the live ammo, which will bring users a bad use experience, and at the same time, it may be difficult to eject smoothly during training and use.

Therefore, it is necessary to propose a new type of dummy ammo structure, which can not only simulate the weight and shape of a dummy ammo, but also simulate the weight distribution of a dummy ammo, and bring users a better use experience.

The present invention provides a dummy ammo, which includes at least one counterweight component and at least one contour component, wherein said contour component has at least one longitudinal axis, and said contour component defines at least one front end and at least one rear end; and

In this specification, for the sake of convenience, words and expressions indicating orientation or positional relationship such as “middle”, “upper”, “lower”, “front”, “rear”, “vertical”, “horizontal”, “top”, “inner” and “outer” are used to illustrate the positional relationship of constituent elements with reference to the attached drawings, only for the convenience of description. The positional relationship of the constituent elements is appropriately changed according to the direction of the described constituent elements. Therefore, it is not limited to the words and expressions described in the specification, and can be replaced appropriately according to the situation.

As shown inand, the present invention provides a dummy ammo, which includes a contour component and a counterweight component, wherein the contour component comprises a cartridge shelland a base; the contour component has approximately the same outline as the live ammo; and the counterweight component comprises a counterweight blockand a connector.

The contour component is a rotating body, has at least one longitudinal axis, defines at least one front end and at least one rear end, and the baseis close to the rear end.

The cartridge shellis provided with a counterweight openingand an inner wall. The cartridge shellhas a generally cylindrical external structure. The counterweight openingis close to the front end, and the counterweight openingand the inner walldefine a cavity, which is arranged inside the cartridge shell, and the counterweight blockis arranged in the cavity.

The counterweight blockhas a counterweight connecting part, and a joint partis arranged on the base.

At least one baffle ring is arranged at the rear end of the contour component, and the baffle ring has an outer diameter larger than that of the cartridge shell, so as to better simulate the shape of live ammo and smoothly realize the function of loading ammunition.

The inner wallis provided with a basic positioning part, which protrudes from the inner walland tends to approach the central axis of the cartridge shell.

As shown in, in this embodiment, the basic positioning parthas a cylindrical structure, the diameter and height of the basic positioning partare smaller than those of the inner wall, and the outer diameter of the counterweight blockis larger than that of the basic positioning partbut smaller than that of the inner wall, therefore the basic positioning partcan limit the position of the counterweight blockin the cartridge shell. The connectorhas a head, and the outer diameter of the head is larger than the inner diameter of the counterweight connecting part. When the connectoris closely connected with the joint part, the counterweight blockcan be limited to a specific position in the cartridge shell, so that the dummy ammo can simulate the distribution of the center of gravity of the live ammo, and the problem that the dummy ammo is not easy to pop up when the center of gravity is low is solved, and the center of gravity does not change when it is used.

The basic positioning partis also provided with a reinforced positioning part, which protrudes from the basic positioning partand tends to approach the central axis of the cartridge shell. In this embodiment, the reinforced positioning parthas a slender rectangular parallelepiped shape and the length is consistent with the basic positioning part.

In this embodiment, the number of reinforcing positioning partsis four, and in other embodiments, it can be other numbers that meet the requirements of functions, such as single, two, and other shapes and structures, such as triangles, isosceles trapezoid, and the like.

In this embodiment, the counterweight blockhas a cylindrical cross-sectional shape, and in other embodiments, it can also have other shapes such as triangle and square, and there is a structure or cavity inside the cartridge shellthat can match the shape of the counterweight block.

The reinforcing positioning partcan better restrict the movement of the counterweight block, but it is not necessary. Therefore, in another embodiment, there may not be the reinforcing positioning part, and the position of the counterweight blockcan be restricted only by the basic positioning part, which can be a single protrusion arranged on the inner wall, or a circular structure in another embodiment.

In this embodiment, the connectoris a bolt, the counterweight connecting partis a through hole arranged in the center of the counterweight block, and the counterweight blockcan move on the connector, and the joint parthas a threaded part matched with the bolt. The connectorpasses through the through hole to connect the counterweight block, the cartridge shelland the base.

In another embodiment, the counterweight blockis fixed on the connector, for example, the counterweight blockcannot move on the connectorby gluing, welding, hot melting, etc. At this time, there is no need to set the basic positioning part.

In another embodiment, the counterweight blockand the connectorare designed as an integral structure, therefore the head of the connectoris large and has a certain weight, which can also ensure the distribution of the center of gravity of the dummy ammo with simulated live ammo, and there is no need to set the basic positioning part.

As shown inand, the cartridge shellis provided with a cartridge shell receiving part, a cartridge shell receiving cavity, a bottom surfaceon the baseopposite to the top surface, and a primer cavityon the bottom surface. The primer cavityis internally provided with a shock absorber, and the shock absorberincludes at least a part of materials that can absorb shock.

In this embodiment, the shock absorberis rubber. The shock absorberis a solid structure with a cylindrical appearance and is fixed in the primer cavityby bonding. In other embodiments, the shock absorbercan be made of other materials, such as silica gel, elastic synthetic materials and other materials that can meet the use requirements. The main function of the shock absorberis to protect the structure of the firing ammunition of firearms and prolong the service life of firearms.

In other embodiments, the shock absorbercan be directly pressed into the primer cavity, and the shock absorbercan only contain part of the shock absorber material.

As shown in, the joint partincludes a receiving sidewalland a joint cavity. The receiving sidewallprotrudes from the top surfacein a direction away from the bottom surface, and the receiving sidewallcovers the joint cavity, which has a higher height than the receiving sidewall, therefore a part of the joint cavityexceeds the top surfacein a direction away from the bottom surface, while part thereof is from the top surfaceto the direction close to the bottom surface. This arrangement has the advantage of reserving more space and ensuring that the connectorcan firmly confine the counterweight blockin the cartridge shell.

In this embodiment, the cartridge receiving partis concave and the baseis convex, and the inner diameter of the cartridge receiving cavityis larger than the outer diameter of the receiving sidewall, so that the cartridge receiving cavitycan accommodate the receiving sidewall, and when the baseis connected with the cartridge shell, the baseis partially inserted into the cartridge shell, and the basecan be better positioned.

In another embodiment, the cartridge shell receiving partis convex and the baseis concave, and the cartridge shell receiving partis inserted into the base.

In other embodiments, the cartridge shelland the basedo not adopt a concave-convex structure, and the cartridge shelland the baseare in contact with each other through two planes, and the two planes are fixedly connected by gluing, hot melting and the like; the cartridge shelland the basecan also be integrally cast or integrally formed without concave-convex structure.

As shown inand, in this embodiment, there is one connector, and the connector, the counterweight block, the base, the cartridge shelland the shock absorber have a common axis, but it is not limited to this. In other embodiments, there may be two or more connectorsor two or more counterweight blocks. At this time, the axes of the connector, the counterweight block, the base, the cartridge shelland the shock absorber are parallel.

As shown in, this is the second embodiment of a dummy ammo, which includes a counterweight block, a cartridge shell, a base, and a pressing block. The counterweight blockis arranged at one end of the cartridge shellnear the counterweight opening, and the cartridge shellis provided with a basic positioning partprotruding from the inner wall, so that the position of the counterweight blockcan be limited. A pressing blockis arranged in the cartridge shellin contact with the inner wall. The pressing blockcan be made of a plastic material with certain elasticity or can be installed with the cartridge shellby interference fit, therefore when installed in the cartridge shell, the pressing blockcan limit the movable position of the counterweight blockwithout other parts for connection.

In this embodiment, there is an interference fit between the baseand the cartridge shell, and the baseis inserted between the cartridge shell, therefore the baseand the cartridge shellcan also be closely connected.

In other embodiments, screw connection, snap connection, hot melt, cold pressing and other fixed connection methods can be adopted between the baseand the cartridge shell.

In another embodiment, the baseand the cartridge shellcan also be integrally cast.

As shown in, this is the third embodiment of a dummy ammo, which includes a counterweight block, a cartridge shelland a base. By adopting an inlay injection molding process between the counterweight blockand the cartridge shell, the cartridge shellforms a counterweight accommodating cavityaround the counterweight blockat a position close to the counterweight opening. At this time, the cavity of the cartridge shell is no longer a cylindrical structure, but a structure composed of two cylinders with different diameters. Since the counterweight accommodating cavityhas a diameter larger than the inner wallof the cartridge shell, the counterweight blockcan be stably fixed at a specific position in the cartridge shell.

As shown in, this is the fourth embodiment of the dummy ammo, which includes a counterweight block, a cartridge shelland a connector. Compared with, the fourth embodiment cancels the base, and the cartridge shellis made of metal. Because of its high density, the wall thickness of the cartridge shellneeds to be thinned to maintain the original weight and center of gravity distribution. At the same time, in order to adapt to the thinned cartridge shell, the diameter of the counterweight blockchanges and the diameter of the counterweight blockbecomes larger. In order to maintain the original weight and center of gravity distribution, Lis smaller than L.

A joint cavityis arranged in the cartridge shell, and the connectorenters the joint cavity, and the counterweight blockis fixed at a specific position in the cartridge shellthrough the basic positioning part.

As shown in, this is the fifth embodiment of a dummy ammo, which includes a counterweight block, a cartridge shelland a base counterweight. The counterweight blockand the base counterweightare all fixed in the cartridge shellby an insert injection molding process. The counterweight blockand the base counterweightare made of metal materials, and the cartridge shellis made of plastic or nylon.

As shown in, this is the sixth embodiment of a dummy ammo, which includes a counterweight block, a cartridge shell, a connector, a baseand a bushing.

The bushinghas a cylindrical structure. The inner diameter of the bushingis larger than the outer diameter of the connector, therefore the connectorcan be put into the bushing. The maximum outer diameter of the bushingis smaller than the inner diameter of the inner wallof the cartridge shell, therefore the bushingcan be put into the cartridge shell. Both ends of the bushingare in contact with the cartridge shelland the counterweight blockrespectively, and the basehas a joint cavityfor matching the connector. When the connectorenters the joint part, tightly connect the counterweight block, bushing, cartridge shell, and base.

As shown in, this is the seventh embodiment of a dummy ammo, which includes a counterweight block, a cartridge shelland a base. After the counterweight blockis put into the cartridge shellthrough the counterweight opening, the counterweight blockis fixed at a specific position of the cartridge shellby gluing or ultrasonic fixing.

In this embodiment, the inner wallof the cartridge shellis provided with the basic positioning part, which can limit the position of the counterweight blockand make it difficult for the counterweight blockto fall off. In another embodiment, the inner wallis not provided with the basic positioning part, and the counterweight blockis fixed at a specific position of the cartridge shellonly by gluing or ultrasonic fixation, and the counterweight blockis fixed at a specific position of the cartridge shell.

As shown in, this is the eighth embodiment of the dummy ammo, which includes a counterweight block, a cartridge shell, a connectorand a base. It further includes a distinguishing partarranged on the cartridge shell.

The function of the distinguishing partis to distinguish live ammo from dummy ammo, so as to avoid confusing the two kinds of ammunition in actual use. In this embodiment, the distinguishing partis a circular opening arranged in the cartridge shell, which runs through the cartridge shell. In other embodiments, the distinguishing partcan be an opening with other shapes, such as square, triangle and the like. It can also be a recess that does not penetrate the cartridge shell, and the distinguishing partis more obvious by filling the recess with pigment. The distinguishing partcan also be arranged at other positions, such as a recess on the base.

As shown in, this is the ninth embodiment of a dummy ammo, which includes a counterweight block, two cartridge shellsand a base counterweight. The two cartridge shellsare assembled by ultrasonic welding. Before assembling, the counterweight blockand the base counterweightare put into the cartridge shells.

As shown in, this is the tenth embodiment of a dummy ammo, which includes two cartridge casings, which are assembled by ultrasonic welding. The cartridge casingsare provided with protrusions at the position close to the counterweight openingand at the other end far from the counterweight opening. After assembling, a hollow cavity is formed in the middle of the cartridge casings, so the weight distribution of ammunition is still close to that of live ammo.

In other embodiments, the hollow cavity is filled with other materials with lower density than the cartridge shell, and there is no hollow cavity, but the weight distribution of ammunition is still close to that of live ammo.
