Device for storing and loading projectiles without propellant charge

Abstract

The invention offers many advantages for shooting sports with unrestricted firearms for those 18 years and older. Large quantities of projectiles can be stored and fed from the same device, and the projectile carriers or belts are lightweight, flexible, and robust, which simplifies overall handling. Loading is independent of the energy storage system, as is the case with magazines. The limitation to projectiles of a specific shape and length is eliminated; only the caliber and maximum length remain relevant.

Description

[0001] The invention relates to a device for storing and loading projectiles without propellant charge for use in pistols or rifles in which the projectile is preferably accelerated by the use of compressed air.

[0002] The device is intended to facilitate the storage and loading of projectiles. State of the art

[0003] Air rifles typically use spring-loaded rotary or stick magazines. Single-loaders are also used, allowing the use of longer bullets.

[0004] Other types of rifles have permanently integrated magazines that must be loaded after each round.

[0005] There are also manual rotary magazines, which have to be rotated manually after each shot.

[0006] Air rifles can also be loaded directly into the barrel without magazines. Disadvantages of the state of the art

[0007] The options mentioned offer limitations in the maximum number of bullets, as well as disadvantages in handling due to the size, mechanical sensitivity, lack of ergonomics, limitation of the bullet length in magazines, as well as lack of fit in the manufacturing tolerances of the weapon. Object of the invention

[0008] The object of the invention is to provide a robust and high-capacity storage and loading solution that is also easy to handle and allows optimal use even with manufacturing tolerances of the weapon. In an advantageous embodiment, a partially or fully automated conveyance of the projectiles to the loading system is enabled. Solution

[0009] The object is achieved by a device according to claim 1. Advantageous further developments are defined in the subclaims.

[0010] The device according to the invention for storing and loading projectiles without propellant charge for use in pistols or rifles comprises: A device for storing and loading projectiles without propellant charge for use in pistols or rifles, characterized in that the device consists of at least one projectile carrier or belt which can be fully detached from the device, which encloses the projectiles and is made at least partially of a material with a fully elastic elongation of at least 33.7%, and a guide for attachment to the weapon by force and / or form fit, which positions the projectiles coaxially with the barrel, wherein when the weapon is reloaded the projectile carrier or belt is transported by means of a conveyor mechanism in order to load the next projectile.

[0011] The guide is firmly connected to the weapon by form and / or force locking and, if designed accordingly, includes a feed mechanism.

[0012] The bullet carrier or belt can be detached from the device, so that the guide can also be used with several bullet carriers or belts, which are transported sequentially for use through the guide.

[0013] The device enables the conversion from a classic magazine system to a belt system with a multiple of the bullet capacity compared to the standard magazine solutions on the market.

[0014] The device enables a particularly high-capacity and robust solution for storing and loading projectiles.

[0015] Advantageous embodiments of the invention are described below: According to another embodiment of the invention, the projectile carrier or belt can be constructed in such a way that several elements can be connected to one another in order to increase the projectile capacity, or one element can be connected to itself in order to change the pack size. According to another embodiment of the invention, the conveying mechanism can be designed to use mechanically stored energy which is stored in advance in the system or to obtain the energy from the kinetic energy of the repetition. According to another development of the invention, the coaxial alignment of the projectiles to the barrel is achieved by insufficient deformation of the loaded projectile chamber, or a mechanical construction engaging in the projectile carrier or belt, which stops the projectile by means of positive locking. According to another development of the invention, the coaxial alignment of the projectiles to the barrel is realized via an elastic property of the device, wherein a preferred locking position of the projectile chambers is achieved coaxially to the barrel. According to another development of the invention, the coaxial alignment of the projectiles to the barrel during manual feeding is facilitated by a tactile marking in the projectile carrier or belt. According to another development of the invention, which does not require an additional molding element, the projectile carrier or belt is transported into an empty projectile chamber by engagement of a conveyor element. According to another embodiment of the invention, the components of the device are designed so that they can be optimally manufactured using additive manufacturing. The FDM printing process is suitable for this purpose, using materials such as TPU, ABS, ASA, and PA. According to other developments according to the claims, the device can be further optimized. Materials:

[0016] Components are not subject to any special exceptions in terms of their size, shape, design, material selection and technical concepts, so that the selection criteria known in the area of ​​application can be applied without restriction.

[0017] The materials only have to meet the requirements of manufacturability and compatibility with gun oils. Advantages of the invention and its further developments:

[0018] By means of the device according to the invention, the projectile carrier or belt can be designed in such a way that the maximum projectile length required by the weapon can be fed, whereby the feeding is independent of the materials and design of the projectiles.

[0019] The projectile carrier or belt does not store any energy to propel the projectiles, so it can be made significantly lighter, more robust and also more flexible.

[0020] The bullet carrier or belt can also withstand falls without any damage that would impair its functionality.

[0021] From the functional principle, there is no relevant limitation on the projectile capacity.

[0022] A large energy storage is not necessary because the repeating movement is used for propulsion.

[0023] Thanks to the possibilities of additive manufacturing, the components can be produced in a resource-efficient manner and in small quantities.
