Description

- • - ORIENTING HELICOIDAL CHARGER FIELD OF THE INVENTION This invention relates to a helical steering loader for containing and delivering, in series, several pellets or projectiles. More specifically, this invention relates to a magazine having a rotating carrier that is oriented each time "the master is operated so that a pellet, or projectile, is delivered from the magazine to the weapon every time it is made. function. ? attQf Mrtq * dej i ven o The usual chargers with helical power supply members are common. Such customary chargers are designed / mainly for use with conventional projectiles and, thus, most are not designed to handle delicate projectiles. In other words, most of these usual chargers impose relatively high forces on the projectiles counted in them and, thus, must be used with durable projectiles. Said loaders are not suitable for use with pneumatically driven air guns and pellets or paintballs which are relatively brittle. For example, some of these conventional chargers rely, in operation, on gravity and pressure or on a belt system to feed the projectiles to the weapon. Such systems will damage the most delicate projectiles, such as pellets and balls with paint. Examples of these usual loaders are described in U.S. Pat. 213555, issued March 25, 1879 to Evans; U.S. Patent No. 84685, issued on December 8, 1868 to Evans; U.S. Patent No. 1285263, issued November 19, 1918 to Lohne; U.S. Patent No. 3088378, issued May 7, 1963 to Boudreau; U.S. Patent No. 3427923, issued February 16, 1969 to Meyer et al .; the North American patent. no. 4034644 / issued ßl July 12, 1977 to Hupp and colab; U.S. Patent 4166408, issued September 4, 1979 to Etsel et al.

However, these loaders also have several disadvantages. For example, some of them depend on the force of gravity to feed the projectiles to the weapon. Others employ a complicated tape arrangement that is not practical for shotguns for airguns. Others are not reliable and suffer damage easily. Examples of loaders designed for use with pellets and paintballs are described in U.S. Patent No. 4819609, issued April 11, 1989 to Tipp'an and in U.S. Patent No. 5166457, issued on November 24, 1992 to Lorenzetti. In view of the foregoing, it is evident that there is a need for a helical loader with orientation, for use with compressed air guns and pellets or paintballs. This invention addresses this need for the art, along with other needs that will be apparent to those skilled in the art once this description is complete. Previous patent aunt who considers this need is srr 4 > U.S. Patent No. 5097816, issued March 24, 1992 to Miller.

This invention provides a guiding loader for storing and delivering projectiles to a weapon. The magazine includes a housing, a drive member, a release member, a rotating member and a camming member. The housing has a first end, a second end, a passage extending from the first end to the second end along a longitudinal axis, a helical member extending partially from the first end to the second end, and step, and an extreme cap on the first end. The drive member is rotatably coupled within the housing and has a plurality of projections or projections for guiding the projectiles along the helical member. The release member is coupled to the second end of the housing and to the actuating member and feeds the projectiles from the housing to the weapon. The rotating member is coupled to the drive member and rotates it. The cam action member is slidably coupled to the rotating member and movable between a first position and a second position. The rotating member is applied to the cam member by sliding. When the cam action member moves from its first position to its second position and the rotating member rotates in a first direction, the cam action member slides relative to the adjacent extension. When the cam action member moves from its second position to its first position, the rotating member rotates in a second direction, engages with the extension and rotates the actuating member. In some embodiments of this invention, the loader further includes a load member. The load member is engaged with the first end of the housing to disengage the rotating member from the actuating member, so that projectiles can be loaded into the actuating member.

In still other embodiments, the rotary member includes a first bearing surface extending parallel to the longitudinal axis and a first inclined surface extending at an angle to the longitudinal axis. The first inclined surface is applied to the adjacent extension when the cam member moves from its first position to its second position and loads the rotating member so that it slides over the adjacent extension. The first bearing surface is applied to the extension when the cam action member moves from its second position to its first position and rotates the driving member. In other embodiments, the rotary member includes a second bearing surface and a second inclined surface similar to the first and second surfaces described above. In other embodiments, the rotating member includes a ratchet disc and a tang fixedly attached to the disc and extending outwardly from the disc, in application of sliding with the camming member. The first and second surfaces extend from the ratchet disc. In other embodiments, the cam action member includes a first end portion extending parallel to the longitudinal axis, a central portion extending angularly of the longitudinal axis and a second end portion extending parallel to the longitudinal axis. In still other embodiments, the central portion of the cam action member pivots the rotating member in the first direction when the cam action member moves from its first position to its second position and pivots the rotary member in a second direction when the cam action member moves from his first - # -position to his second position. The chargers according to this invention offer many advantages over prior art chargers, including the following. An advantage of the loaders according to this invention is that they reduce to a minimum the force on the projectiles contained in them, in order to reduce the risk of damage if they are using fragile projectiles. Specifically, the helical rib, the corrugations and the arms support and protect the projectiles. The arms gently feed the projectiles to the release member. Another advantage of the loaders according to this invention is that they are very reliable, since they are actuated by the cam action latch. Another advantage of the chargers according to this invention is that they are robust and withstand damage caused by the operator. Yet another advantage of the chargers according to this invention is that they are easy to manufacture, since they have only a few parts and are easy to assemble. Other advantages and outstanding features of the loaders according to this invention will be apparent from the description. gave, mñ & Gíi? ¡< * l n ..? , .lü & -tUbujgs Referring to the drawings that are part of this description: fig. 1 is an exploded view of a helical steering loader in accordance with the present invention; fig. 2 is a longitudinal section of the shell Cylindrical housing of the loading of fig. 1 with the other parts of the loader shown in continuous line and with sample bucks added for clarity, and representing the loader in the loading position; fig. 3 is a longitudinal section of the cylindrical shell of the magazine housing of FIG. 1, with the other parts of the charger shown in solid line, and that - + - represents the charger in the charged position; fig. 3A is a cross section of the magazine of Figs. 1-3 along line A-A of FIG. 3, which illustrates the ratchet in its prime position; fig. 4 is a cross section of the magazine of FIGS. 1-3 along line A-A of FIG. 3, which illustrates the ratchet moving from its first position to its second position; fig. 4A ßß a cross section of the magazine of figs. 1-3 along line A-A of the fxg. 3, which illustrates the ratchet in its second position; fig. 5 is a cross section of the magazine of FIGS. 1-3 along the line A-A of FIG. 3, which illustrates the ratchet moving from its second position to its first position; fig. 5A is a cross section of the magazine of Figs. 1-3 along line B-B of FIG. 3, illustrating the stop member sliding on the carrier when it is rotated by the ratchet; fig. 6 is a longitudinal section of the cylindrical shell of the magazine housing of FIG. 1, with built-in sample pellets for clarity; fig. 7 is a bottom plan view of the cylindrical shell of FIG. 6; fig. 8 is an end view from the right of the cylindrical shell of FIG. 6; fig. 9 is a side view of the carrier of the magazine of FIG. 1; a flg. 10 is an end view from the left of the carrier of FIG. 9; fig. 11 is an end view from the right of the carrier of FIG. 9; fig. 12 is an end view from the right of the ratchet disk of the magazine of FIG. 1; fig. 13 is a bottom view of the ratchet disk of the magazine of FIG. 1, partially torn away, to illustrate the openings of the legs; - # - fig. 13A is a cross section of the ratchet disc of FIGS. 12 and 13 along line C-C d fig. 12; fig. 14 is an end view from the left of the plug of the magazine of FIG. 1; fig. 14A is an end view from the right of the plug of the charger of the figs. 1 and 14; fig. 14B is a cross section of the plug of the fige. 14 and 14A along line D-D of fig. 14; fig. 15 is a side view of the sear of the grinder of FIG. 1; fig. 16 is a side view of the body of the loading assembly of the magazine of FIG. 1; fig. 17 is an end view from the right of the end cap of the flg loader. l; and fig. 18 is a side view of the end cap of FIGS. 1 and 17.

Preferably, six uniformly spaced ridges 60 extend outwardly from the cylindrical web 61, parallel to the longitudinal axis 34. The ridges 60 are diagonally positioned so that the pellets 12 individually fit between adjacent ridges 60. The outermost diameter of the ridges 60 is smaller than the innermost diameter of the rib 36, so that the carrier 16 can rotate inside the rib 36. The arms 66 extend outwardly from the end of the grooves 60, together with the second end 32 of the cylindrical body 26, The ends of the arms 66 are slightly curved in the opposite direction to the direction in which the carrier 16 rotates (as represented by the arrow 63 in Fig. 1). The curvature of the arms 66 is such that they protect and guide the pellets 12 within the end cap 22, as described below. The shaft 66 extends outwardly from the cylindrical web 61 along the longitudinal axis 34, towards the first end 30 and is cylindrical. The orifice 64 is cylindrical and extends partially through the center of the cylindrical web 61 at the second end 32 of the cylindrical body 26 along the longitudinal axis 34. The ratchet or rotating member 18 includes a main hub 70 and a tang 72. The ratchet 18 rotates in a first direction 71 and in a second direction 73, see Figs. 4 and 5. The ratchet IB is applied with the »grooves 60 and -16- is rotatably coupled inside the housing 14 next to the first end 30 of the cylindrical body 26., as described in what follows. The main body or disk 70, as illustrated in FIGS. 1, 12, 13 and 13A, includes an outer ring 75, bases 77 of raised legs, elastic legs 74, leg openings 76, a central hole 78 and a bore 80 dß spike. The main body 70 as cylindrical. The outer ring 75 forms, basically, the outer circumference of the disc 70. There are two leg bases 77 which are diametrically opposed. The leg bases 77 are integral with the outer ring 75 and extend above or outwardly relative to the surface of the outer ring 75, 15. Preferably, there are two such elastic legs 74 and such leg openings 76. Each leg 74 extends from a leg base 77 and is located on a leg opening 76. The two pairs of legs 74 and leg openings 76 are identical and are separated at 1603. The leg openings 20 76 are located in, and are larger than, the legs 74, so that each leg opening 76 can receive a leg 74 in it, as described below. Each leg 74 extends in arc around the center of the main body 70. Each leg 74 includes a tooth / "- 25 82 at its outermost end, with a bearing surface 84 and an inclined surface 86. The inclined surfaces 86 start at the free end of the legs 74 and tilt outwards, up to the bearing surfaces 84 The support surfaces 84, ex-30 extend outwards parallel to the longitudinal axis 34. Each leg opening 76 extends through the arcuate main body 70, around the center of the main body 70. The central hole 7B is cylindrical and extends through the center of the main body 70. The spigot bore 35 is cylindrical and extends perpendicularly to the longitudinal axis 34, partially through the main body 70, preferably spaced 90"apart from the ratchet - * - ratchet 82. The spigot bore 80 is in alignment with the L-groove 38 of the cylindrical body 26, when the magazine 10 is properly mounted, the pivot pin 72 preferably being cylindrical. It is press fit into the bore 80 and extends outward from the main body 70, through the L-slot 38 the housing 14 when the loader 10 is properly assembled. The cam lock 20, as seen in FIG. 1, includes a groove 90, preferably of shape, essentially, rectangular. The throat 90 receives the lower end d of the pin 72. The cam lock 20 can take many forms. For example, it may be a trigger, a pump or a lever for mounting a weapon. When the weapon to which the magazine 10 is associated is operated, the bolt 20 moves back towards the first extra 30, to a first position 98 and forward, towards the second end 32, to a second position 99. Stated another way, the bolt 20 ß moves in a linearly reciprocating motion between positions 98 and 99 when the weapon is operated. The second end cap assembly or release member assembly 22 includes a cap 101 and a detent 109. The cap 101 includes, essentially, an inner wall 102, an outer wall 104, and a helical side stop 106, as illustrated in figs. 1, 14, 14A and 14B. The end cap 22 is substantially cylindrical and is coupled to the housing 14 at the second end 32 of the cylindrical body 26. When the magazine 10 is properly assembled, the inner wall 102 is adjacent to the splines 60 and arms 66 of the carrier 16. The outer wall 104 forms the outer end wall at the second end 32 of the cylindrical body 26 and has substantially the same diameter as the cylindrical body 26. The outer wall 104 has an elongated slot 103 therein, which receives the sear 109 , as it is written in what follows. The inner wall 102 has a feed throat 108, a hole 110 and a hole 111 therein, and - t # - a plug 112 extending inwardly. The feed throat 108 has a start tip 122 and an end tip 124. The feed throat 108 extends into the inner wall 102 and, in this embodiment, has a triangular configuration in cross section. The feed throat starts at the start tip 122 and deepens continuously as it extends in arc to its end tip 124. The end tip 124 is aligned with the cutout 40 of the housing 14 when the loader 10 is mounted in an appropriate way. The holes 110 and 111 extend from the inner wall 102 to the groove 103 in the outer wall 104 (see Fig. 14B). The holes 110 and 111 receive the legs 130 and 131 of the sear 109, as described below. The flange or helical side wall 106 includes a first end 116 and a second end 120. The helical side wall 106 increases in height outward, from its minimum height in the inner wall 102, at its first end 118, to its maximum height in the second end 120. The side wall 106 has a diameter slightly smaller than the inside diameter of the cylindrical body 26, so that the end cap assembly 22 is received within the body 26. In this way, the side wall 106 fits snugly at the second end 32 of the cylindrical body 26, such that the outer wall 104 forms an end of the housing 14. The second end 120 of the helical side wall 16 angles inwardly to form a wedge shape (see Fig. 14B). The second end 120 d of the tab 106 has a slot 121 therein, adjacent to the inner wall 102 of the end cap 22. The side wall 106 also includes projections 114 projecting therefrom, spaced approximately 1802 apart. The shoulders 114 are positioned so that they can be received in a pair of holes 42 of the cylindrical body 26 to connect the plug 101 to the cylindrical body 26.

- - The plug 112 is cylindrical and is received in the hole 64 of the carrier 16, when the. Charger is mounted properly. The latch 109 is received in the slot 103 and in the holes 110 and 111 and includes a head flange 125, coupling arms 126, and legs 130 and 131, as illustrated in FIGS. 1 and 15. The head flange 125 is substantially flush with the outer wall 104 when the magazine is properly mounted. Coupling arms 12 extend outwardly from the head shoulder 125 and spring elastically into the hole 110. The legs 130 and 131 extend perpendicularly perpendicularly to the arms 126. The leg 131 includes a stop member 128 which is received. inside the hole 111. The stop member 128 includes a stop surface 132 and an inclined surface 134. The leg 130 extends outwardly from the innermost leg 131. When the magazine 10 is properly assembled and is attached to a weapon, a part of the latter presses the leg 130 towards the second face 104 and loads the legs 131 so that the stop member 128 is pushed through the hole 111. , to application with the fingers 66. The loading assembly 24, as illustrated in figs. 1 and 16-18, includes a body 140, a spring 142 and a first end cap 144. The load assembly 24 is coupled to the first end 30 of the cylindrical body 26, so that the body 140 can be pivoted at 90e between a first position 146 discharged, as illustrated in FIG. 2, and a second loaded position 148, as illustrated in FIG. 3. The body 140 includes a head 150, a part 153, arms 152 and legs 151. The head 150 extends outwardly from the middle portion 153, beyond the first end 30 of the cylindrical body 26, when the magazine is properly mounted and can be caught to pivot the body 140 of the load member between its positions 146 and 148, unloaded and load, respectively. The legs 151-sa extend outward from the middle portion 153. Each leg 151 includes a pin 155 and a retaining jaw 154. The legs 151 form, together, a cylinder with side grooves to provide elasticity. The slotted bore 156 is formed between the legs 151. The legs 151, when the loader 10 is properly assembled, extend into the first end 30 of the cylindrical body 26 and are rotationally received in the hole 78 of the ratchet member 18, by assembly by elastic jump. The grooved bore 156 receives the shaft 62 of the carrier 16 and the spring 142. The arms 152 extend outward from the middle 153 and perpendicularly to the longitudinal axis 34 / and are spaced from the head 150. The spring or load member 142 it is, preferably, a common helical spring. The spring 142 is received in the grooved bore 156 formed by the legs 151, and the spring 142 itself receives the shaft 62 of the carrier 16. The first end cover 144 includes an end wall 157, collars 160 and shoulders 162. The first end cap 144 is coupled to first end 30 of cylindrical body 26. End wall 157 has substantially the same diameter as cylindrical body 26 and has a slot 150 therein. The collars 160 substantially have the same diameter as the inside of the cylindrical body 26, so that the first end cap 144 fits snugly within the first end 30 of the cylindrical body 26. The slot 158 of the end cap extends through the the face 157 of the end cap and receives the body 140 of the load member therethrough. The end cap slot 158 is designed in such a way that the arms 152 of the load member 24 will be mounted through the slot 158 when the arms 152 are substantially in alignment with the slot 158, but will not be mounted through the slot 158. slot 158 when they are misaligned with respect to it. In the first position downloaded 146, that is, when the arms 152 are in -alignment with the slot 158, the arms 152 of the body 140 of the load member are urged through the end cap slot 158 by the spring 142 acting on the holder 16. In the second loaded position, 146, the arm 152 of the body 40 of the load member extends perpendicularly to a slot 158 of the end cap, thus blocking the ratchet member in application with the holder 16. The shoulders 162 they extend from the face 157 of the end cap and enter with elastic jump in holes 42 0 of the first end 30 of the cylindrical body 26, to couple the first end cap 144 with the cylindrical body 26. Mounting and re-assembly To mount the loader 10, the carrier 16 is inserted through the second end 32 of the cylindrical leather 26. The spring 142 is then inserted into the grooved bore 156, formed by the legs 151 of the body 140 of the load member, and inserted into the body. The legs 151 push through the central hole 78 of the pawl 18, and are snap-coupled with the pawl 18. More specifically, the legs 151 push 0 elastically inward, until they fit through the central hole 78. The legs 151 push outwardly once the jaws 154 pass through the central hole 78 of the pawl 16, such that the jaws 154 and the pin 155 engage the pawl 18 to the legs 151. The pawl 25 is engaged, so that it can be made rotate, with the legs 151. The shaft 62 is then inserted into the grooved bore 156 and the spring 142. The pawl 18 is oriented so that the spigot bore 80 aligns with the L-groove 30 of the cylindrical body 26. The first end cap 144 is then coupled to the first end 30 of the cylindrical body 26, the head 140 of the drop member 24 extending through the slot 158 of the first end cap 144, specifically, the shoulders 162 are at Uneven with the holes 42 of the first end 30 of the cylindrical body 26 and coupling the first end cap 144 to the first end 30 by snap-fitting. At the second end 32-1 * - the cylindrical body, the end cap 22 is coupled thereto, also, by snap-fitting. Specifically, the shoulders 114 snap into the holes 42 in the second end 32, to engage the lid end 22 to the second end 32. The plug 112 of the plug 101 is received in the hole 64 of the carrier 16. Finally, one end of the pivot pin 72 is pressed into the bore 80 for it by the ratchet lß, through the L-slot 36 of the housing 14. 0 The loading of the magazine 10 with pellet 12 is illustrated in FIG. 2. The body 140 of the load member is positioned so that the arms 152 are in alignment with the slot 158 of the end cap. In this position, the spring 142, which has one end resting against the carrier 16, forces the body 140 of the loading assembly outward, to its outermost position, the position 146, as illustrated in FIG. 2. In this position, the upper part of the legs 151 rests against the area of the end cap 144 which is immediately adjacent to the slot 158 (since the upper part of the legs 151 will not fit through the groove 158). ) and prevent further movement outward of the loading assembly 24. When the body 140 of the load member is in the outermost position 146, the pawl 18 is disengaged from the carrier 16 and the pin 72 is located on the first branch, 48, of the L-slot 38. When the pawl 18 is disengaged from the carrier 16, it rotates freely within the cylindrical body 26, since the bearing surfaces 84 of the pawl 18 are not in eplication with the striae 60 of the carrier 16, The pellets 12 are then loaded through the cutout 40 in the second extram of the housing 14, between each flute 60, as desired. The carrier 16 can be rotated in such a way that all the "valleys" included between adjacent splines 60 can be filled with pellets 16, that is, each valley is in alignment with the slot 40. During this rotation, the arms 66 of the ridges 60 at the second end 32 push or slide on the inclined surface 134 of the stop member 128. Once the loader 10 is loaded with pellet 12, the body 140 of the load member is forced inward, to the innermost position 148 and is pivoted at 90 °, as illustrated in fig. . 3. During this movement of the body 140 of the load member, the wall 157 of the end cap is received between the arms 152 and the head 158 of the body 140 of the load member, to lock the body 140 of the load member. The pin 72 is moved to a first end or intersection 50 of the second branch 48 of the L-slot 38. Before inserting the tang 72 of the magazine 10 into the cam lock 20, the ratchet 18 must be pre-adjusted. This is done by manually moving the pin 72 from the extreme primar 50 of the second branch 48 to the second end 52 of the second branch 48, as illustrated in FIG. 5. As the pin 72 moves, the pawl 18 rotates in the second direction 73 (see FIG. 5), and the abutment levers 84 engage with the adjacent adjacent groove 60 and rotate the carrier 16. until the pin 72 reaches the second end 52 of the second branch 48, as illustrated in FIG. 3A. During this rotation, at the second end 32 of the housing 14, a groove 60 pushes or slides on the inclined surface 134 of the stop member 128 of the leg 131 of the sear 109, as illustrated in FIG. 5A. The pin 72 is then introduced into the first end portion 92 of the cam groove 90 of the cam action bolt 20, this being in its first position 98. In operation, the cam action bolt 20 starts in its first position 98. are the pin 72 received in the first end portion 92 of the cam groove 90. When the weapon to which the magazine 10 is associated is activated, the cam action lock 20 is moved from its first position, 98, to its second position, 99. This action displaces the groove 90 in relation to the pivot pin 72 in such a way that the pin 72 moves, from being received in the first end part 92 to being received in the second end part 96., through the angled part 94. With the cam action latch 20 limited to a linear reciprocating movement, this movement of the 5-cam action cam 20 with respect to the pin 72 causes it to rotate in arc. about the longitudinal axis 34. As the cylindrical envelope 26 is stationary, this movement results in the spigot 72 moving from the second end 62 of the second branch 48 of the L-slot 38, to the first end 50 of the branch 48. The central angle part 94 displaces, with cam action, the pivot pin 72 * As the pin 72 is fixed to the pawl 18, this action of the pin 72 rotates the pawl 18 in a first direction 71, as it is illustrated in figs. 4 and 4A. When the ratchet 18 rotates in its first direction 71, the inclined surfaces 86 of the teeth 82 of the pawl, are applied with the following adjacent grooves 60, as illustrated in FIG. 4, and 'they are on them. The carrier 16 is held in position and does not rotate due to the stop member 128 at the second end 32 of the cylindrical body 26. Specifically, the stop surface 132 of the stop member 128 is in application with a stria arm 66 60 ß prevents rotation of the carrier 16. When the cam action latch 20 is moved from its second position 99, back to its first position r ~ 98, the cam lock 20 moves relative to the tang 72, in such a way that it moves from the second end part 96 to the first end part 92, through the angled part 94. This action rotates the tang 72 in arc around the longitudinal axis 34, the tang 72 moves, in the second branch 48 of the L-groove 38, from the first end 50 to the second end 52. This rotational movement of the pin 72 also rotates, simultaneously, the main body 70 of the pawl 18 and the second sense 73, as It looks on the flg. 5. When the ratchet is rotated in the first direction 73, the bearing surfaces 84 of the teeth 82 of the ratchet are applied to one of the grooves 60 and, thus, rotate the carrier 16 with the ratchet 18. The carrier 16 is rotated, preferably, at a distance substantially equal to the diameter of a pellet. When the carrier 16 is rotated, the arms 66 at the second end 32, push or slide on the inclined surface 134 of the stop member 128, as illustrated in FIG. 5A. Further, as the carrier 16 rotates, the pellets are propelled along the carrier 16 by the housing propeller 14. A pellet 12 is guided by a groove 60, the helical side wall 106 of the plug 101, the throat of the pellet. feed 108 of the plug 701, and is released from the charger 10 by the cutout 40 of the housing 14, and enter the weapon to which the charger 10 is associated. This process can be repeated, and another gun shot from the charger can be discharged to the gun. 10, until it is empty of buckshot. Then, the magazine 10 can be topped with pellets 12, in the manner described above. Various modifications, improvements and other made-.
