FR2740997A1 - Device for loading of paint balls into compressed air gun - Google Patents

Abstract

Paint balls are fed into a compressed air gun from a magazine (D) located below the line of sight of the gun. At the magazine base is a guide gutter or rail (D3) for directing the paint balls stored in the magazine to an outlet orifice (D4) located opposite the inlet orifice (C5) in a guide tube (C). A flexible cable (B1) has its sheath (B2) fixed on one of the movable parts of the gun and on a piston elevator (C7*). The cable transmits to the piston elevator all movement phases and actions of one of the movable gun parts. The piston elevator re-creates these movements in order to supply the paint balls to the gun. The piston elevator will pass, according to its position, a paint ball within the lower part of the guide tube (C6). It then seals the inlet orifice with the paint ball raised beyond the intermediate zone of the guide tube. A flexible non-return strip (C3) in the intermediate maintains the ball in the upper part of the guide tube (C1).

Description

The invention relates to a device for loading paintballs in order to allow the supply of a compressed air gun drawing these paintballs.
The loading of these paintballs is traditionally carried out by a tank magazine having a conical base, connected to the gun by a tube. The paintballs put in bulk inside this tank magazine are automatically loaded into the compressed air gun under the effect of their weight and gravity
This tank store has the following disadvantages
- to be located above the gun thus revealing the presence of the user before he can use his gun
- to prevent any aim for the user.

- to desequilihoer the pistol
- to be unsightly.

 The device according to the invention makes it possible to remedy these drawbacks thanks to the use of a reservoir magazine situated below the line of sight. The shape of this reservoir magazine is studied in order to rebalance the gun, refine and improve the lines. of the compressed air gun. However, this tank store will not have the same functions as the tank store traditionally used. Indeed it felt directly from the charger using gravity as a means of loading. On the other hand, the functions of the tank magazine according to the invention, are to store the balls, awaiting for loading. which because of the position of this tank store. can not be done under the simple effect of ia gravity but by using the device according to the invention.

The device according to the invention comprises
- As a first characteristic, a tank store n or your balls will be introduced in bulk via a loading orifice. This reversing store is composed of a rigid envelope of rounded shape with at its base a gutter or guide rail presenting the paintballs towards an exhaust orifice

How it works:
The arming or resetting of the air pistol and the different phases and related movements will be through the borrowing and transmission transmission set reproduced by the lifting piston as well
1 Phase I
- intake position cylinder head
- intake position lift piston, a ball enters the lower part of the lift tube (see 12 of 10/12).

? Phase 2
- cylinder head shutter position, arching,
- lifting piston closing position. projection of the ball beyond the flexible non-return lamella. in the upper part of the guide tube (see 2 of 10/12).

3 Phase l
- intake position cylinder head
- intake position lifting piston (the lifting piston returns to the side thanks to the flexible non-return strip), entry of a new ball in the lower part of the guide tube (cf3 "from 11/12).

4 Phase 2
- cylinder head shutter position, chambering,
- lifting piston closing position, advanced ball beyond the flexible non-return strip in the upper part of the guide tube and thrust of the previous ball (see 4 "from?)
The operations must be repeated a certain number of times depending on the length of the tube and the diameter of the ball until the balls reach the intake tube of the air pistol.

5 Phase I
- cylinder head intake position, a ball enters the air pistol and releases a step allowing the admission of a new ball in the upper part of the tube,
- intake position lifting piston, entry of a new ball in the lower part of the guide tube (see 5 of 12/12).

60Phase2:
- cylinder head shutter position, recess of the ball previously admitted into the gun in the "firing" position
- lifting piston closed position, advanced of the ball in the upper part of the guide tube and thrust of previously admitted balls (see 6 "from 12/12).

 The pistol will be loaded. After each shot, the rearming will cause a new ball to be raised and loaded either by the user (manual reset gun) or automatically (automatic or semi-automatic gun).

 It should be noted that this loading will be carried out for an instant under the effect of gravity, in fact according to current systems the intake tubes of the pistols are all oriented upwards, to allow the guide tube to penetrate there. follow, it will be bent. Thus, the paintballs will fall by themselves into the gun intake tube according to their position at the curve of the guide tube.

 This therefore justifies the fact that the lifting piston will have to perform the same movements, phases and actions as the cylinder head. However, (see Plate 9/12) in the case of a vertical intake tube placed below the air pistol, the movements, phases and actions of the lifting piston with respect to the cylinder head must be reversed and the use of 'a damping piston will be made mandatory, in fact when the cylinder head goes into the intake phase, the lifting piston will automatically go into the shutter phase. step up of the paintball, destroying the paintball because the lifting piston will crush the paintball against the cylinder head, the latter still slightly blocking the gun's intake tube.

 The function of the damping piston is to absorb the thrust which crushes the paintball against the cylinder head, while the cylinder head passes completely into the intake position. During the advance of the breech, the damping piston will allow the maintenance of this ball within the pistol, the time that the breech is partially started its closing movement.

 The reversal of the phase and action movements, of the cylinder head and of the lifting piston will be carried out simply by changing the orientation of the grip of the borrowing and movement transmission assembly on the moving parts used directly or indirectly for the arming or resetting the pistol (pulling, pushing).

 The hose or cable of the borrowing and transmission transmission assembly slides inside the sheath of this same assembly. According to particular embodiments, the flexible or borrowing cable for transmitting movements may be partially rigid, in particular when it is parallel to the axis of the gun barrel and / or when it is parallel to the axis of the guide tube. It can be external to the device and gun or directly integrated into them.

Thus, the body of the gun and the riser tube will serve as a sheath. The adjustment system B 5 and B 6 can be integrated at any point in the travel of the hose. The adjusting screw B 6 can be integrated directly into the shutter plug. The sheath and flexible or borrowing cable and transmission of movements may for example be of the same type as the sheaths or flexible used in model aircraft or bicycle braking cable. The orientation of the borrowed movement transmission hose or cable can be reversed, whether on the lifting piston or on the moving parts of the pistol directly or indirectly used to arm or rearm it. In summary, the borrowing system and transmission of movements can be of any kind, its function being to transmit the action and movement phases linked to the arming cycle. Its profile, size and diameter can be any. Likewise, the profiles, sizes and dimensions of the reservoir magazine, of the guide tube, of the lifting piston may be any as long as their respective functions are ensured.

 The lift tube can be oriented in any direction, it can be partially or completely rigid, the sheath C O can be used so as to connect the upper end of the guide tube to the gun intake tube.

 The tube i ateur can be an integral part of the body of the gun. be nestable on the gun's intake tube or be independent of it. The tank store may be an integral part of the lift tube, or be independent of it. of its interlocking on the riser tube will slide so as to present an orifice allowing the paintballs to pass from the exhaust port of the reservoir magazine towards the inlet orifice of the guide tube, conversely during its disengagement a return spring will bring the sliding drawer back to the closing position of the exhaust opening of the tank magazine. The lifting piston assembly may be of different shapes, in order to allow the lateral or axial action of the borrowing and movement transmission assembly. . It is possible to add a C 25 *, C 26 * damping system to improve its efficiency. C 27 * or an ascent assistance system. for example a spring placed between the lifting piston and the blanking plug.

 The entire device may be completely independent of the pistol with the only connection thereto the CO sheath and the borrowing and transmission transmission assembly connected respectively to the moving parts serving directly or indirectly for arming or rearming the gun and gun inlet tube. Thus, the entire device can be directly worn by the user.

 The sheath C O may be a sheath generally used for the protection of electrical wires. Its inside diameter should simply be slightly greater than the diameter of the hinge ball. The C O sheath has the advantages of being flexible, light and resistant. Its ringed shape will have the advantage of always keeping the same profile and internal diameter thus protecting the paintball, the flexibility of the electrical sheath is obtained thanks to the accordion rings located between the rigid rings.

 The flexible strip may consist of a thin strip of copper about 5 / 10ths thick or of any other material which can provide the flexibility necessary for the passage of the paintball. The size and shape of the flexible non-return strip will vary depending on the diameter of the paintball.

 The size of the entire device will be governed by the size and dimension of the gun and the size and gauge of the paintball used.

 The reservoir magazine, the guide tube, the coupling sleeve and the lifting piston can be made of plastic material in several injection molding operations. If in the selected system the reservoir magazine is an integral part of the guide tube, these two parts can be obtained in a single injection molding operation.

 The device according to the invention is particularly intended for supplying paintballs with compressed air gun paints drawing these paintballs.
