The present disclosure relates to a paintball marker loading system and method, and in particular to an improved latching or locking interface between the loader and paintball marker.
In the sport of paintball and other sports for launching projectiles, a projectile launcher, such as a paintball marker, is used to propel spherical paintballs towards a target and a paintball loader, or hopper, is used to hold a quantity of paintballs and to supply those paintballs to the paintball marker. For ease of discussion, the present invention is discussed in connection with paintball markers but the invention is also related and applicable to other projectile launching devices, such as airsoft guns.Traditionally, the paintball is fired with pressurized gas that is expelled through, for example, a bolt. In use, the paintball is loaded into the breech, the bolt is pressed against the paintball such that the face of the bolt is in contact with the rear of the paint ball. The air passed through the breech to force the paintball through the barrel of the marker.
Hoppers or loaders are well known to feed a supply of paintballs into the breech of a paintball marker. Typically, paintballs are inserted into the loader. The loader is then attached to a top side of the paintball marker where a direct pass-through is provided between the chamber of the loader and the breech of the paintball marker so that paintballs may freely flow from the loader into the breech by gravity. The loader is typically secured to the top of the paintball marker by some type of clamp or other releasable mechanism. However, these loaders are often difficult to quickly remove and replace as is often required during gameplay. For example, there is a need to quickly remove an empty loader and replace it with a second spare loader that is pre-filled with paintballs to avoid extended interruptions in game play.
Also, since the loaders include an open free path for the paintballs to travel from the chamber of the loader, through the feed neck and then into the breech of the marker, care must be taken when installing a loader that is filled with paintballs. More specifically, during the handling and installation of the second, there is a need to invert the loader so its feed neck can be mated with the feed collar on the paintball marker. During this inversion, it is possible that paintballs may undesirably fall out of the loader through the feed neck.
For the foregoing reasons, there is a need for a loader mechanism that is easy and quick to install and remove. There is also a need to provide a loader mechanism that can prevent the unwanted falling out of paintballs when the loader is not installed on a paintball marker.
The latching/locking loader mechanism of the present invention provides a quick-release latch mechanism where a user can unlock and lock the attachment of the loader to the paintball gun quickly and easily without the use of tools. The latching/locking mechanism stays locked or unlocked without further use of tools.
The present invention additionally, or alternatively, provides a reliable and secure mechanism to prevent unwanted unloading of the hopper upon inversion to install into a paintball marker. For example, a spring-biased gate can be provided in the path of the paintballs, namely, in the feed neck of the loader. In an uninstalled state, the spring-biased gate can prevent paintballs from freely flowing through the neck of the loader due to, for example, gravity.When the loader/hopper is installed on the paintball marker, via a feed collar, deflection posts on the feed collar can push the spring-biased gate out of the paintball path in the feed neck of the loader so that paintballs may freely pass from the storage chamber of the loader and then into the breech of the paintball marker. Separation or disconnection of the loader from the paintball marker can result in the deflection posts being disengaged with the spring-biased gate thereby permitting the gate to again reside in the path of the paintballs in the loader to prevent the paintballs from undesirably exiting the loader.

Turning first to
The loader 100 can, in general, be formed as a single unit which can accommodate a plurality of paintballs 400 in a hopper 102 which can be expelled from the attached marker 300. In some embodiments, the loader 100 can be formed from two hemispheres, or halves, a first side 102a and a second, mirrored, side 102b. The two halves 102a, 102b can be secured to one another via a plurality of fasters (not shown), such as screws. In the illustrated embodiment, as shown in
Extending downward from the lower end 109 of the hopper 102 is a neck 110, as best seen in
The rectangular portion 112b of the keyhole shape of the neck 100 can be sized to accommodate the spring-biased gate, generally referred to as 120, of the instant embodiment. The spring-biased gate 120, in the illustrated embodiment, is a V spring extending down from the bottom surface 109b of the lower surface 109 of the hopper 102. The upper end 122a of a first arm 122 of the V-spring can be embedded in the lower surface 109, as shown. The illustrated spring-biased gate is preferably a V-shaped spring, but the spring can be any known shape including a W-, U-, O-, S- J-, Z- C-, N-, or M-shape. The spring-biased gate 120 can be formed from any suitable material including, but not limited to, an elastic plastic and metals. In the illustrated embodiment, a first arm 122 of the V-spring 120 can extend down from a bottom surface, or rim,109b of the hopper 102. The first arm 122 extends substantially parallel to the through axis A.
Alternatively, the first arm 122 can extend at an angle relative to the through axis A. The first arm 122 can extend downward, towards the paintball marker 300, to a lowest most point 122 from which a second arm 124 can extend upward and radially inward, relative to the through axis A, into the circular portion 112a of the keyhole. The first arm 122 of the spring 120 can be located in the rectangular portion 112b of the keyhole cross-section and the second arm 124 can extend from the rectangular portion 112b into the circular portion 112a. The amount that the second arm 124 extends is a function of diameter of the paintballs 400 that are intended to be blocked. In other words, the distance D between the end of the second arm 124a and the opposite side wall 144a of the neck 110 is less than the diameter of a paintball 400. When the gate 120 is in the expanded configuration, as shown in
Advantageously, the gate 120 is configured to be biased into the locking configuration when the loader 100 is not attached to the feed collar 200 or the marker 300, as the rest state of the gate 120 is the expanded V-shape. As will be discussed below, the gate 120 is configured to be actuated, or deflected, into the second configuration when the neck 110 of loader 100 is inserted into the feed collar 200, as seen in
It should be understood that the spring-biased gate 120 shown herein and discussed above is just one of many different configurations and structures that may be employed to controllably gate of the paintballs when the loader is not connected to the feed collar/paintball marker. The gate can be any structure that blocks the paintball path when the loader is not installed and does not block the path when the loader is installed. As a further example, the gating/blocking device may be a sliding gate, similar to a garage roller shutter door. As yet another example, the gating device may be a spring-operated lever arm. Therefore, a door may be provided to completely cover the outlet port of the loader so that it is completely sealed when separated from the paintball marker.
Also, the gating device of the present invention may also be configured and arranged in an electronic loader that includes a motor drive to help feed and load the paintballs from the loader and into the paintball marker. In this case, the gate may operate a switch that switches the motor drive of the electronic loader on and off. For example, when the loader is installed and ready to use and the gate (in whatever form) is positioned to permit paintballs to pass, a structure may be provided so that the gate actuates a switch to turn on the motor drive of the electronic loader. Similarly, when the loader is removed from the paintball gun, movement of the gate to now block the paintballs will switch off the motor drive.
The neck 110 of the loader 100 can additionally include a locking slot 130. The locking slot 130 can be located anywhere on the outer perimeter of the neck 100. In the illustrated embodiment, the locking slot 130 is located on a distally extending flange 132. The flange 132 can have a thickness t that is less than the thickness T of the rectangular portion 112b of the neck 110. The locking slot 130 can be in the form of a U- or C-shaped cut out that is sized to receive a locking cross bolt 236 of the feed collar 200, discussed further below. While the illustrated locking slot 130 has a rectangular, or square, shape the locking slot 130 can have any cross-sectional shape. Advantageously, when the loader 100 is inserted into feed collar 200 and the locking cross bolt 236 is engaged, the loader 100 can be fixed to the respective paintball marker 300. Thus, the loader 100 is secured to the marker 300 with the pathway from loader 100 to the marker being open thereby being ready for use by a user.
Looking to the feed collar 200 itself, the feed collar can be used to connect the loader 100 to the marker 300, to lock the loader 100 to the marker 300, and to move the gate 120 from the locked configuration to the released configuration.In general, the feed collar 200 acts as a bracket to connect the feed port 302, located in a top wall of the breech 304 of the marker 300, to the feed neck 110 of the loader 100, as seen in
The lower end 202a of the feed collar 200 can be configured as a clamp collar style bracket which can be tightened onto the feed port 302 of the paintball marker by rotation of the screw 204 through the through openings 206. The through openings 206 can be disposed in respective ears 207a, 207b, which are spaced a distance apart from one another by a gap which extends radially inward towards the central axis A of the feed collar. Thus, the lower end 202a of the feed collar 200 can have a variable diameter D1 lower through hole 208. By adjusting the screw 204, the diameter D1 can be enlarged or tightened around the feed port 302. As the screw 204 is tightened the gap is lessened, thereby reducing the variable diameter D1. The flange through hole 208 can extend upward towards an inner cylindrical flange 210. The inner cylindrical flange 210 can have a lower surface 212a define a stop which the feed port 302 can abut when fully inserted into the feed collar 200 to prevent an over insertion, as seen in
At the upper end 202b of the feed collar 200, there can be a keyhole like cross-section to match the outer cross section of the feed neck 110 of the loader 100, as seen in at least
Proximate to the respective ears 207a, 207b, are two upstanding deflection posts 220a, 220b which can extend upward from an outer edge of the inner cylindrical flange 210. While two deflection posts 220a, 220b are shown one or any number of posts can be used. The two deflection posts 220a, 220b are arranged such that upon insertion of the neck 110 of the loader 100 into the feed collar 200, the second arm 124 of the spring-biased gate 120 can be deflected, or pivoted in the direction R, seen in
While an embodiment of the spring-biased gate is shown in
As noted above, the gate 1120 can include a first arm 1126 and a second arm 1128 which intersect to form the generally “L” shape. The first arm portion 1126 can be a shorter length than the second arm portion 1128, as the first arm portion can be sized to rotate within the feed neck 1110 of the loader 1100. In the illustrated embodiment, a pivot pin 1127 can be rigidly formed with, or attached about the pivot point of the gate 1120 and can be longer than a width of the gate 1120. The pivot pin 1127 can have a diameter that is sized to be received within retaining holes in the feed neck 1110, to allow the gate 1120 to freely pivot therewith. On one side of the gate 1120, a spring groove 1129 can be formed to receive and catch an arms of the spring. In general, the torsion spring 1124 can be a double helical spring having at least three arms 1125a, 1125b, 1125c and a helical portion 1123. The helical portion 1123 can be disposed about a portion of the pivot pin 1127a which is longer than a portion of the pivot pin on the other side of the gate 1120. In general, the helical portion 1123 can have a minimum inner diameter that is at least the same as, or larger than, the outer diameter of the pivot pin 1127. A first arm 1125a of the torsion spring 1124 can rest in a groove 1129ab can rest against a lower surface 1109b of the hopper, as seen best in
In the illustrated embodiment, the loader100 is installed whereby the feed neck 110 of the loader 100 is inserted into the feed collar 200 so that upstanding deflection posts 220a, 220b deflect the second arm 124 of the spring-biased gate 120. As the second arm 124 is deflected, it no longer extends into the circular portion 122a through hole to allow the paintballs 400 to exit from the loader 100, through the feed neck 110 and then into the breech 302 of the paintball marker 300.
Once the feed neck 110 of the loader 100 is disposed in the feed collar 200, the loader 100 locks to the feed collar 200. As shown in
The locking cross-bolt 236 is generally rectangular in shape and includes a recess 237 through one face. The recess 237 has a cross-sectional shape and dimension that is substantially the same as the cross-sectional shape and dimension of the locking seat 232. When the recess 237 is aligned with the locking seat 232 the flange 132 is able to move vertically relative to the feed collar 200, as shown in
When the loader 100 is disposed in the feed collar 200, the locking slot 130 and the pass-through port 234 are aligned. The locking slot 130 can be arranged, relative to the feed collar 200, such that the locking cross-bolt 236 can slide through both the locking slot 130 and the pass-through port 234 at the same time, as seen in
When the locking cross-bolt 236 is moved through the pass-through port 234 to its unlocked position, as shown in
Also, it is common for a user to pre-fill multiple loaders with paintballs. Filled loaders, when not in use, are commonly attached to user's belt or clothing. When the current loader is empty, the user can easily replace the current loader with a new filled loader. Therefore, it is common to handle and move around pre-filled loaders. With the use of the spring-biased gating of the present invention, pre-filled loaders can be easily handled without fear of paintballs falling out. This is especially useful during paintball competitions.
As shown in
This is made possible by the two-position locking cross-bolt 236. The cross-bolt recess 237, when aligned with the locking slot 130 of the loader allow the loader to move vertically, i.e. separated from the paintball marker 300. When not aligned, the cross-bolt 236 resides in the locking slot 130 of the flange thereby prevented such vertical movement and separation. While two positions are shown, it is contemplated that there may be additional positions as needed. As is shown in
It will be appreciated by those skilled in the art that various changes and modifications can be made to the illustrated embodiments without departing from the spirit of the present disclosure. All such modifications and changes are intended to be covered by the appended claims.
