FIELD
The present invention is generally related to a toy projectile launcher, such as a toy dart launcher, with a high capacity magazine.
BACKGROUND
Toy launchers that discharge soft projectiles, such as toy foam darts or toy foam balls—commonly referred to as toy “guns” or “shooters”—are well known in the art. The toy projectiles are designed to safely impact upon a target without causing injury or damage.
Toy launchers may use one of various different mechanisms for launching the projectiles. One common mechanism for launching toy projectiles from a toy launcher involves the application of compressed air on the projectiles to launch them. The compressed air must be carefully controlled so as to only be in fluid contact with the projectile or projectiles that are intended to be launched at a particular time. Another known mechanism to launch toy projectiles is to feed the toy projectiles to contact one or more rotating flywheels and thereby propel the projectiles forward toward a target.
Prior art launchers use one of a variety of different types of magazines for toy darts. For example, one type of magazine has a clip or cartridge for feeding darts to a barrel of the launcher. Another type of magazine holds the darts and advances the darts to firing position with a biasing spring when released upon activation of a trigger.
As another example, a straight magazine may hold darts in one or more rows of dart holders, with a possible offset between the rows. A straight magazine may, for example, be input horizontally into a compatible toy launcher and passes sideways through the launcher as darts are launched. Such a magazine has been used with a compatible compressed air toy launcher, but is not ideal as a magazine that moves sideways requires a clearance on either side of the launcher and must be reinserted each time that it is reloaded.
Another known type of magazine is a circular drum-style magazine.
One such prior art launcher, for example, includes a drum that has a single ring of toy dart holders arrayed around the drum. This launcher launches the darts with motorized flywheels positioned in front of the drum and darts are pushed one at a time from the drum to the flywheels for launch. A shortcoming of this launcher is that the number of darts that can fit in a single ring on a drum is limited in practice by the size of the launcher.
A different prior art launcher includes a drum having two concentric rings of darts where the concentric rings are aligned with one another and the toy darts are launched sequentially first from one ring and, after all of the darts in one ring are launched, then the darts in the other ring are launched. This launcher requires a switch between launching from one ring to another after one ring is fully depleted of darts and is inefficient as it requires two rotations of the drum to launch all of the darts.
To address the above, an improved toy launcher and a drum to be used therewith was developed and resulted in an invention by Applicant described in pending U.S. patent application Ser. No. 16/007,660, filed Jun. 13, 2018, now U.S. Pat. No. 10,533,821.

DETAILED DESCRIPTION
The present invention is generally related to an improved toy launcher with a drum for launching projectiles. To achieve a high capacity, the drum includes a ring of projectile holders that can accommodate at least two concentric rings of projectiles. In embodiments, the projectile holders are adapted to hold one or more types of projectiles, such as toy foam darts, foam balls, or other objects. A pushing rod for one or more of the at least two concentric rings of projectiles are simultaneously activated and advance toward a back of the drum to push the projectiles, one at a time, from the front of the drum toward one or more flywheels that propel each projectile out of the launcher and toward a target. In embodiments, the pushing rod(s) is(are) spring-loaded or gear-driven, and the one or more flywheels may be motorized. The projectiles are launched in a sequence that empties a first concentric ring of projectiles before launching projectiles from a second concentric ring.
Referring to FIGS. 1 and 2, a launcher 100 for projectiles in accordance with an exemplary embodiment of the present invention includes a handle 10 for holding the back end of launcher 100, a front handle 52 for holding the front of launcher 100, a trigger 20 for launching projectiles, a designated space or recess 30, shown in FIG. 2, for accepting a magazine such as a substantially circular drum 60 (see FIG. 1) into which toy darts or other objects are to be loaded, and a barrel 40 at the front of launcher 100 out of which the darts are propelled. Barrel 40 extends between an opening (not shown) in front wall 34 and a front opening 115 of launcher 100. Launcher 100 further includes a projectile advancement assembly having a pushing rod 70, and launcher 100 also includes flywheels (not shown) within an outer shell 12 between the opening in front wall 34 and front opening 115, a power supply, such as battery compartment (not shown) into which batteries may be placed to power launcher 100, and an on/off switch 22 to turn on and off the flywheels. Recess 30 is located between a back wall 32 and a front wall 34.
As shown in FIG. 2, launcher 100 includes opening 210 on a bottom portion of front wall 34 of recess 30 for receiving an attachment element 120 (such as a knob and the like) of drum 60, as will be described in further detail below with reference to FIG. 3. Correspondingly, a similar opening 210b is incorporated on a bottom portion of back wall 32 of recess 30 for receiving a corresponding knob (not shown) on a back portion of drum 60. FIG. 2 further illustrates a spring-loaded push member 67 and a notched stopper 260 (described in further detail below) integrated to a top portion of recess 30 of launcher 100. Additionally, a drum advancement pusher (hook element) 222 and a push rod 70 are incorporated to the back wall 32 in recess 30, which will be described in further detail below with reference to FIGS. 5A and 5B.
FIG. 3 is a perspective view of drum 60 according to an exemplary embodiment of the present invention. As shown in FIG. 3, drum 60 may include twenty (20) integrated dart holders 61 with aligned partial enclosures for holding two aligned concentric rows of darts 63—in other words, affording storage of forty (40) darts 63 in drum 60. As shown in FIG. 3, drum 60 includes an inner ring of support portions 61a and an outer ring of support portions 61b to form each of the dart holders 61. Correspondingly, drum 60 further includes enclosure flaps 164 for holding in the outer ring of darts 63 around their front dart caps 63a by partially reaching around both sides over each dart 63 on the outer ring, as illustrated in FIG. 3. FIG. 3 further illustrates an attachment element 120, which may be a rotatable knob or the like, for detachably engaging a corresponding rotatable attachment mechanism, including opening 210 illustrated in FIG. 2. Additionally, FIG. 3 illustrates one of the darts 63 on the inner ring that is partially extended outward from a front opening 169 to illustrate a manner in which such a dart 63 may be launched.
FIG. 4 is a partial front view of the drum 60 shown in FIG. 3 to illustrate respective dimensions of darts 63 and front openings 169 according to an exemplary embodiment of the present invention. As shown in FIG. 4, front openings 169 are dimensioned slightly smaller across one dimension (12.7 mm) than dart 63 and dart cap 63a (13 mm), and are dimensioned slightly larger than dart 63 and dart cap 63a across another dimension (17.4 mm). As described before, the front openings 169 are so dimensioned to provide for darts 63 on the inner ring of drum 60 not exiting out the front of drum 60 when, say, launcher 1 is tilted or pointed downward. At the same time, the dimensions of these openings (69) still allow push rod 70, with sufficient forward pushing force though back opening 66 (FIGS. 3 and 9C), to squeeze the resilient dart tip 63a (and dart body 63b) through the front opening (169) during launch. As illustrated in FIG. 4, openings 169 may be oval in shape and may be radially aligned with a slight tilt away from a downward path of a dart 63 from the outer ring into the inner ring by being pushed by member 67 when drum 60 is rotated during launch according to an exemplary embodiment of the present invention. From the front view of FIG. 4, openings 169 are tilted to the left and a downward path of dart 63 would follow a rightward tilt in correspondence with a counterclockwise rotation of drum 60 during launch.
In embodiments, drum 60 may be non-removable from launcher 100. Having a drum 60 as a separable component may be desirable for purposes such as for compact packaging and shipping of launcher 100, or replacing drum 60 as needed or desired (e.g., if broken or for use in launching a different type of projectile, to name a few) or to enable a user to carry a second loaded drum to increase the user's firepower.
In alternative embodiments, a retractable rod (not shown) may be used in place of openings 210 and 210b on the bottom of launcher 100 to allow drum 60 to be loaded into launcher 100—i.e., drum 60 may incorporate a corresponding aperture in place of attachment element 120 shown in FIG. 3 for fitting onto such a retractable rod. Once drum 60 is loaded into launcher 100, the rod may be returned to a closed position to retain drum 60. In embodiments, the rod may be secured in a closed position with a releasable lock or latch so that drum 60 is not accidentally released from launcher 100. The rod may be retracted from the center of drum 60 to allow drum 60 to be removed. In embodiments, a release button (not shown) or the like may be incorporated in launcher 100 to release the lock or latch.
In the illustrated embodiment, drum 60 is configured to shoot toy darts. Darts may be loaded into drum 60 before drum 60 is loaded into launcher 100 and/or darts may be loaded and/or refilled in drum 60 after drum 60 is loaded into the launcher.
FIG. 5 is a close-up bottom view of toy dart launcher 100. As shown in FIG. 5, launcher 100 includes resilient holders 410 and 410b within openings 210 and 210b, respectively. Resilient holder 410 includes a fitted hook for fitting around and rotatably retaining attachment element 120 on the front of drum 60 shown in FIG. 3. Correspondingly, resilient holder 410b also includes a fitted hook for fitting around a similar retaining attachment element (not shown) on the back of drum 60. FIG. 5 further illustrates the arrangement of push member 67 and notched stopper 260 at the top portion of recess 30 in launcher 100.
FIG. 6A is a partial front cross-sectional view of launcher 100 along line A indicated in FIG. 5, and FIG. 6B is a partial front cross-sectional view of launcher 100 along line B indicated in FIG. 5. As shown in FIG. 6A, spring-loaded push member 67 includes a push surface 67a and a release surface 67b. According to an exemplary embodiment, push member 67 is internally mounted to launcher 100 around a pivot mount (not shown) at an upper end of release surface 67b. As shown in FIGS. 6A and 6B, pusher (hook element) 222 is movable along a track 224. According to an exemplary embodiment, hook element 222 is coupled to, for example, front handle 52 shown in FIG. 1 via an internal drum advancement mechanism (not shown) such that a back and forth, cocking motion by a user on handle 52—in a manner similar to a pump-action shotgun—would compel hook element 222 to move from the right hand position shown in FIGS. 6A and 6B towards a left portion of track 224 (see arrow in FIG. 6B) and back. Correspondingly, drum 60 incorporates a ring of ridges and notches (not shown) on the back surface thereof that are positioned to engage hook element 222 so that the aforementioned movement would cause drum 60 to rotate by an angle corresponding to the distance travelled by hook element 222 along track 224.
FIG. 6B also illustrates a notch 260b in stopper 260. According to an exemplary embodiment, notch 260b is dimensioned to fit approximately around a support portion 61b on drum 60, as shown in FIG. 3. Additionally, stopper 260 is biased downward—by a spring and the like—so that it is retractable by an upward force from the support portion 61b during rotation of drum 60 but would hold drum 60 in place around the support portion 61b when notch 260b is aligned therewith.
As shown in FIG. 5, hook element 222 incorporates an inclined trailing surface 222b. According to an exemplary embodiment, hook element 222 is biased outward from back wall 32 of launcher 100 by a spring (not shown) so that hook element 222 is retractable inward into back wall 32 when an inward force is exerted thereon. Accordingly, when hook element 222 is moved from the original position shown in FIG. 6B leftward—by, say, a backward pull on handle 52—the leading flat surface of hook element 222 engages a ridge (not shown) on the back surface of drum 60 and pushes drum 60 to rotate in the counterclockwise direction according to the orientation shown in FIG. 6B. When hook element 222 is returned from the leftward position back toward the original position shown in FIG. 6B—by, say, a forward return of handle 52—the inclined trailing surface 222b slides along a next ridge (not shown) on the back surface of drum 60, pushing hook element 222 inward into back wall 32 until hook element 222 clears the next ridge, whereby the internal biasing spring (not shown) pushes hook element 222 back outward from back wall 32 for engaging the next ridge in a next incremental rotation of drum 60.
As illustrated in FIG. 6A, push surface 67a is angled upwardly in relation to release surface 67b, which extends from an internal pivot mount. The pivot mount forms a spring-loaded hinge against launcher 100, where a spring (not shown) exerts a downward bias on member 67. According to an exemplary embodiment of the present invention, drum 60 is rotated in a counterclockwise direction per the front views shown in FIGS. 6A and 6B (by hook element 222 pushing leftward), after a dart 63 is launched and drum 60 is advanced to a next dart 63—either by a pump action on handle 52 as described above or by an automatic firing/advancing mechanism. Drum 60 shown in FIGS. 3 and 4 is advanced one slot where a next outer support portion 61b is rotated to a position that aligns approximately with notch 260b on stopper 260. In the meantime, a next dart 63 on the outer ring is pushed down to the inner ring by push member 67 for launch—either by another trigger pull (semi-automatic) or by continuous trigger pull (automatic). In embodiments, projectile holder 61 within each of the inner and outer concentric rings are of substantially equal dimensions, are substantially-equally spaced apart from one another, and are spaced apart as little as possible to fit as many darts as possible in the drum at a time. In the illustrated embodiment, for example, there are twenty (20) projectile holders, although drum 60 may be alternatively configured to hold more or fewer darts.
The arrangement of projectile holders 61 that hold darts 63 in two (2) concentric rings, along with the use of spring-loaded push member 67 to push the darts 63 on the outer concentric ring into the emptied inner concentric ring, allows for a simplified launcher construction to move a single pushing rod 70 to launch a projectile. Accordingly, push surface 67a exerts a downward force against a dart 63 on the outer concentric ring of darts 63 held in projectile holders 61 around drum 60.
According to an exemplary embodiment, the presence of a dart 63 on the inner ring shown in FIG. 3 would prevent a corresponding dart 63 on the outer ring in the same aligned holder 61 from being pushed in by push surface 67a of spring-loaded push member 67. Referring back to FIG. 6A, push surface 67a is a curved surface so that a portion leading an apex of the curve (rightward portion in FIG. 6A) would exert more force on a dart 63 than the portion trailing the apex of the curve. Consequently, push member 67, being spring loaded around a pivot connected to the release surface 67b, would be pushed upward by the dart 63 on the outer ring—if it is obstructed by another dart 63 in the same holder 61 on the inner ring of drum 60—until it is cleared toward the release surface 67b as drum 60 is advanced, in the counterclockwise direction in FIGS. 6A and 6B. In contrast, when an inner ring position of holder 61 corresponding to a dart 63 on the outer ring is empty, the leading portion of push surface 67a would exert sufficient force to push the dart 63 inward and downward into the empty inner ring position of the holder 61—and, correspondingly, a next firing position.
FIG. 7 depicts an exploded view of another exemplary embodiment of drum 60 for use in launcher 100. Drum 60 may include two (2)—front 60a and back 60b—portions that are assembled together. As shown in FIG. 7, a ring of projectile holders (or chambers) 61 spaced around the periphery of back portion 60b of drum 60. In accordance with an exemplary embodiment of the invention, the ring of projectile holders 61 on back portion 60b of drum 60 is formed by an inner ring of support portions 61a and an outer ring of support portions 61b. As illustrated in FIG. 7, the inner ring of support portions 61a forms an inner circumferential support structure having respective rounded portions for receiving and holding toy projectiles in respective projectile holders 61. Correspondingly, the outer ring of support portions 61b forms an outer circumferential support structure having respective rounded portions for receiving and holding toy projectiles in respective projectile holders 61. Accordingly, inner support ring 61a and outer support ring 61b together form rings of two (2) rounded support portions that are spaced apart and dimensioned to accommodate corresponding two (2) concentric rings of projectiles in an aligned arrangement—in other words, an inner projectile and an outer projectile in an aligned arrangement in each projectile holder 61. Thus, the ring of projectile holders 61 each having the two (2) rounded support portions 61a and 61b is configured to receive and hold two (2) concentric and aligned rows of toy projectiles around drum 60.
As further illustrated in FIG. 7, the two (2) front and back portions 60a and 60b of drum 60 are assembled by coupling insertion members 64a on front portion 60a with receptacles 64b on back portion 60b. According to an exemplary embodiment of the present invention, receptacles 64b are formed between inner rounded support portions 61a to form a circular ring in correspondence with the inner ring of rounded support portions 61a—and, thereby, also serve to divide the projectile holders 61 for the inner concentric ring of toy darts. As illustrated in FIG. 7, the receptacles 64b are cylindrical in shape and extend in the forward direction from the back portion 60b parallel to the firing/storage direction of toy darts 63. Correspondingly, insertion members 64a on the front portion 60a are also cylindrical in shape and aligned with receptacles 64b to form a corresponding ring around front portion 60a. Insertion members 64a are dimensioned to be smaller than receptacles 64b for insertion therein. Accordingly, drum 60 may be assembled by inserting the ring of insertion members 64a on front portion 60a into the corresponding ring of receptacles 64b on the back portion 60b. One or more fastening elements (not shown) are further incorporated to hold the front and back portions 60a and 60b together. Such fastening elements may be detachable for easy disassembly of drum 60. For example, the inner ring of toy darts 63 may be more conveniently loaded with the drum 60 disassembled. According to such an exemplary embodiment of the present invention, the inner ring of toy darts 63 is inserted proximate the respective inner rounded support portions 61a between the receptacles 64b and, once filled, the drum 60 is assembled. The outer ring of toy darts 63 may also be loaded before or after drum 60 is assembled.
As shown in FIG. 7, front portion 60a further incorporates a ring of corresponding pairs of resilient flaps 64c that are aligned with insertion members 64a (and receptacles 64b when drum 60 is assembled) for separating toy darts 63 on the outer ring of drum 60. At locations corresponding to insertion elements 64a, the pairs of flaps 64c are slanted to form V shapes outward from insertion element 64a. Consequently, as illustrated in FIG. 7, the resilient flaps 64c are slanted against one another in a manner corresponding to trapezoidal legs that support the two sides of an outer toy dart 63 against outer support portion 61b. Operationally, the resilient flaps 64c slant inward to support the outer toy dart 63 where a diameter of the toy darts 63 is slightly larger than a distance between the flaps 64c at the points at which the toy darts 63 are supported. According to an exemplary embodiment of the present invention, resilient flaps 64c may be formed with a resilient material and dimensioned to provide sufficient mechanical strength to support the weight of a toy dart 63 but would also provide sufficient flexibility and resilience to allow a supported toy dart 63 to be pushed inward between the flaps 64c towards the inner ring of toy darts 63 supported by inner support portions 61a, as described in further detail below.
As shown in FIG. 7, each dart 63 has a cap 63a that is affixed to an elongate dart body 63b, where the cap 63a has a configuration that enables the dart to relatively accurately target a person or object and travel a relatively long distance, while impacting the target in a safe manner. Darts are loaded into projectile holders 61 via the front side of the back portion 60b of drum 60 after assembly, as shown in FIG. 8. As shown in FIGS. 7 and 8, the toy darts 63 may be loaded into the inner concentric ring—i.e., onto inner rounded portions 61a—before assembling drum 60 or by sliding under flaps 64c and bending/straightening the darts 63 into back portion 60b when drum 60 is assembled. The toy darts 63 may be loaded into the outer concentric ring—i.e., at outer support portions 61b—by sliding the dart bodies 63b under outer support portions 61b in back portion 60b and placing the caps 63a between adjacent slanted flaps 64c, as illustrated in FIG. 8.
When loaded, each dart 63 is fully within a corresponding projectile holder 61 in that a front wall 65 on the front portion 60a of drum 60 is positioned to hold and align the darts 63 that are held on an outer ring around drum 60. Correspondingly, as shown in FIGS. 7 and 8, front wall 65 includes a ring of front openings (e.g., 69) for allowing darts 63 to be pushed forward for launch.
FIG. 8 is a perspective view of an assemble drum 60 with the four darts 63 shown in FIG. 7 loaded therein to illustrate operation of spring-loaded push member 67. Darts 63 may be loaded before drum 60 is loaded into launcher 1 or may be loaded and reloaded after drum is inserted into launcher 1. As shown in FIGS. 7 and 8, inner support ring 61a extends forward from back portion 60b of drum 60 to meet front portion 60a so that an inner ring of projectiles (darts) 63 is fully supported. As further illustrated in FIG. 7, inner support ring 61a includes a ring of fitting holes 64b in which corresponding rods 64a on front portion 60a are inserted for an aligned assembly of drum 60. As will be described in further detail below, once drum 60 is assembled, outer support ring 61b on back portion 60b is receded from inner support ring 61a so that an opening is provided for a spring-loaded push member 67 to exert a force on darts 63 on an outer concentric ring in holders 61 towards the inner concentric ring. According to an exemplary embodiment of the invention, spring-loaded push member 67 includes a push surface 67a, a release surface 67b, and a pivot mount 67c. As illustrated in FIG. 7, push surface 67a is angled upwardly in relation to release surface 67b, which extends from pivot mount 67c. Pivot mount 67c forms a spring-loaded hinge against launcher 1 at a pivot point (not shown) on launcher 100.
FIG. 9A is a front view, FIG. 9B is a side view, and FIG. 9C is a back view of an assembled drum 60 corresponding to the perspective view of FIG. 8 with the four darts 63 shown in FIG. 7 loaded therein to illustrate the operation of spring-loaded push member 67. As shown in FIGS. 9A-9C, darts 63 are loaded in projectile holders 61 of drum 60 in aligned concentric rings defined by the respective inner and outer rings of rounded support portions 61a and 61b. A first of the concentric rings is located substantially at a first radius from the center of drum 60 and a second of the concentric rings is located substantially at a second radius from the center of the drum, where the second radius is different from the first radius. The rounded support portions 61a and 61b of projectile holders 61 on back portion 60b of drum 60 are, thus, spaced in an aligned arrangement such that the darts 63 held in a first concentric ring are aligned in an angular direction with the darts 63 held in a second concentric ring.
FIGS. 9A-9C illustrate one (1) dart 63 being held on an inner (first) concentric ring and three (3) darts 63 being held on an outer (second) concentric ring in respective projectile holders around drum 60. FIGS. 9A-9C illustrate the four (4) toy darts in a configuration where the inner concentric ring of toy darts has been emptied (from firing) and a first dart on the outer concentric ring is pushed down into the inner ring for firing, as illustrated by reference numeral 63a on the dart cap of the dart 63 that is aligned with the opening on front wall 65 on the front portion 60a of drum 60 in FIG. 9A. According to an exemplary embodiment of the present invention, drum 60 is rotated in a counterclockwise direction per the front and perspective views shown in FIGS. 8 and 9A and in a clockwise direction per the back view shown in FIG. 9C when a dart 63 is launched and drum 60 is advanced to a next dart 63. Correspondingly, as illustrated in FIG. 9C, the dart body 63b of the first dart 63 that is pushed by member 67 is aligned with an opening 66 on the back portion 60b of drum 60 such that pushing rod 70 can be moved forward in order to push the dart 63 forward to flywheels (not shown) for firing. According to an exemplary embodiment of the present invention, drum 60 shown in FIG. 9C is advanced one slot where 63b is rotated to a position that aligns approximately with pivot mount 67c (and a corresponding pivot point on launcher 100) and is pushed forward (via opening 66 by push rod 70 shown in FIG. 2) through a front opening on front wall 65 corresponding to location 69 shown in FIG. 9A. In the meantime, a next dart 63 on the outer ring is pushed down to the inner ring by push member 67 for launch—either by another trigger pull (semi-automatic) or by continuous trigger pull (automatic). In embodiments, projectile holder 61 within each of the inner and outer concentric rings are of substantially equal dimensions, are substantially-equally spaced apart from one another, and are spaced apart as little as possible to fit as many darts as possible in the drum at a time. In the illustrated embodiment, for example, there are twenty (20) projectile holders, although drum 60 may be alternatively configured to hold more or fewer darts. A center hole 120b allows for a retractable rod (not shown) or the like to pass therethrough and retain drum 60 in launcher 100. As described above, drum 60 may incorporate a knob 120 for fitting into holder 410 in opening 210 on the front and a corresponding knob (not shown) for fitting into holder 410b in opening 210b on the back.
The arrangement of projectile holders 61 that hold darts 63 in two (2) concentric rings, along with the use of spring-loaded push member 67 to push the darts 63 on the outer concentric ring into the emptied inner concentric ring, allows for a simplified launcher construction to move a single pushing rod 70 to launch a projectile. Accordingly, push surface 67a exerts a downward force against a dart 63 on the outer concentric ring of darts 63 held in projectile holders 61 around drum 60. FIGS. 9A-9C illustrate the situation where a dart 63 on the outer ring has been pushed down into an empty inner ring. According to an exemplary embodiment of the present invention, the presence of the dart 63 on the inner ring shown in FIGS. 9A-9C would have prevented a corresponding dart 63 on the outer ring in the same aligned holder 61 from being pushed in by push surface 67a of spring-loaded push member 67. Consequently, push member 67, being spring loaded, would have been pushed upward by the dart 63 on the outer ring until it is cleared toward the release surface 67b as drum 60 is advanced, in the counterclockwise direction in FIG. 9A (or in the clockwise direction in FIG. 9C).
FIG. 9C illustrates a view of a back side of drum 60. As shown in FIG. 9C, the back of drum 60 includes a respective opening 66 for each projectile holder 61 positioned to correspond with an inner concentric ring of the darts 63 held in drum 60. Each opening 66 is sized to be smaller than an outer diameter of elongate dart body 63b to prevent a dart 63 held in the respective projectile holder 61 from exiting out of the back of drum 60. At the same time, opening 66 is sized to enable a pushing rod, described below, with a diameter smaller than opening 66 to pass through opening 66 and push a dart loaded in drum 60 out through the front opening 69 on front wall 65. Corresponding to the above, the front openings (including 69) on front wall 65 are sized slightly smaller than front tip 63a of dart 63 (e.g., 1 mm smaller in diameter or width) across one dimension (e.g., circumferential direction around drum 60) and slightly larger across another dimension (e.g., radial direction outward from drum 60) so that darts 63 on the inner ring of drum 60 do not exit out the front of drum 60 when, say, launcher 1 is tilted or pointed downward. At the same time, the dimensions of these openings (69) still allow push rod 70, with sufficient forward pushing force though back opening 66 (FIG. 9C), to squeeze the resilient dart tip 63a (and dart body 63b) through the front opening (69) during launch. According to an exemplary embodiment of the present invention, openings (69) may be oval in shape and may be radially aligned, as illustrated in FIG. 9A. As described below, openings may also be tilted in relation to the radial direction of drum 60 according to an exemplary embodiment of the present invention.
FIG. 10 depicts a side view of drum 60 of FIGS. 7-9C without darts in accordance with an embodiment of the present invention. In the illustrated embodiment, outer concentric substantially cylindrical support portions 61b of projectile holders 61 of drum 60 are connected to each other by elongated ribs 68 that may extend, for example, between a range of approximately one quarter of the width of drum 60 starting at the back side of drum 60 to strengthen drum 60. In embodiments, outer support portions 61b extend forward beyond elongated ribs 68 of the drum 60 so that, in embodiments, spring-loaded catch (stopper) 260 shown in FIGS. 2, 5, and 6B may be adapted to press against an outer surface at outer support portions 61b or ribs 68 to limit rotational movement of drum 60 when a projectile is launched. As drum 60 is incrementally rotated, the catch 260 is released from outer support portions 61b or ribs 68 to allow drum 60 to rotate before the next projectile holder 61 is aligned for launch. Again, flaps 64c are disposed near the front of drum 60 to divide adjacent darts 63 on an outer concentric ring and for providing minimal support for these darts 63 away from an aligned inner concentric ring of darts 63 stored in drum 60 so that the outer darts do not hinder, via friction or otherwise, the inner darts during launch. Push member 67 disposed between outer support portions 61b and flaps 64c can, thus, contact and exert downward force on darts 63 on the outer ring in drum 60.
FIG. 11 is a perspective view of a launcher 100 with drum 60 illustrating another exemplary embodiment of the present invention. As illustrated in FIG. 11 and in contrast from FIGS. 2, 5, 6A, and 7-9C, push member 167 may be anchored to launcher 100 at an extension portion 1205. Extension portion 1205 is shown in FIG. 11 with semi-transparency in order to illustrate the arrangement of push member 167 and may be made with an opaque material.
FIG. 12 is a bottom view showing a designated space or recess 30 of the launcher 100 shown in FIG. 11 according to an exemplary embodiment of the present invention. As shown in FIG. 12, spring-loaded push member 167 is attached and anchored to extension portion 1205 at pivot point 172. Push member 167 is anchored on an opposite side in relation to a pushed dart 63 than the manner in which push member 67 shown in FIGS. 7-9C is arranged. In other words, while both push members 67 and 167 have two angled surfaces (e.g. 67a and 67b, and 167a and 167b), push member 67 contacts and pushes an outer ring dart 63 on the surface (67a) away from the anchor point (67c), and push member 167 contacts and pushes an outer ring dart 63 on the surface (167b) proximate the anchor point at pivot point 172. This distinction may be attributable to flaps 64c holding up the outer ring darts 63 shown in FIGS. 7-9C requiring slightly larger downward force than outer ring darts 63 shown in FIG. 3, which are held up on the outer ring solely by inner ring darts 63. In other words, the outer ring darts 63 shown in FIG. 3 may drop downward into the inner ring via gravity when a corresponding inner ring dart 63 has been launched and the dart holder 61 is near vertical at a firing position. Push member 167 provides additional downward force to ensure that such a dart 63 would be not held up on the outer ring by friction, misalignment, or the like. As shown in FIG. 12, launcher 100 includes opening 1210 on a bottom portion of front wall 34 of recess 30 for receiving knob 120 of drum 60 illustrated in FIGS. 3 and 4. Correspondingly, a similar opening 1210b may be incorporated on a bottom portion of back wall 32 of recess 30 for receiving a corresponding knob (not shown) on a back portion of drum 60.
The configuration shown in the figures and described above reduces the materials needed to construct drum 60 and, therefore, further improves upon the material costs and operation of launcher 100. For example, with drum 60 being substantially lighter, in the semi-automatic mode—where each pull of the trigger 20 would rotate the drum—the physical effort would be reduced—due to a lighter mass. Correspondingly, the energy required for launch in the automatic mode would also be reduced—thus extending battery life for launcher 100.
While particular embodiments of the present invention have been shown and described in detail, it would be obvious to those skilled in the art that various modifications and improvements thereon may be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such modifications and improvements that are within the scope of this invention.
