Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to archery bows and arrows and, more particularly, to an attachment to a bow especially adapted for launching arrows.

2. Description of the Prior Art

The invention described herein is an improvement of the bow-attached, arrow launching apparatus by the same inventor, David L. Hurd, and disclosed in U.S. Pat. No. 5,769,065, incorporated herein by reference and disclosed in U.S. Pat. No. 5,520,163, incorporated herein by reference.

The present invention continues to retain the combination of desirable features set forth in U.S. Pat. No. 5,769,065 and in U.S. Pat. No. 5,520,163. More specifically, with the present invention, the following combination of desirable features are retained: (1) can employ arrows that are shorter than conventional length; (2) provides a bow and bow string that can be sufficiently stretched to effectively propel a shorter-than-conventional-length arrow; (3) is able to readily convert a conventional bow into a novel bow that can be employed to launch shorter-than-conventional-length arrows; (4) provides arrows which permit the arrows to propelled by a bow string without employing a slot or nock at the rear ends of the arrows; (5) permits pulling back the rear end of an arrow and the bow string without using a pinching and pulling action on the rear end of the arrow; (6) provides a track for launching a shorter-than-conventional-length arrow wherein the track has a relatively short length for storage purposes; (7) provides a launching device for a shorter-than-conventional-length arrow that can be employed with a vertically oriented bow; (8) provides a bracket member can be used as a support for a plurality of arrows; (9) provides a magnetic attraction between the back of an arrow and a bow string guide assembly so that the arrow is retained in the launcher assembly until it is launched off of the launcher assembly; and (10) providing rapid speed in loading and shooting an arrow by utilizing the proximity of the bracket for supporting a plurality of arrows and the launcher assembly and by utilizing the magnetic attraction between the back of an arrow and a bow string guide assembly.

Still other features would be desirable in a bow-attached, arrow launching apparatus and are provided by the present invention. For example, in U.S. Pat. No. 5,769,065, the bow string guide assembly 30 is pulled back to tension the bow string. To launch the arrow, the bow string guide assembly 30 is released. As long as the bow string guide assembly 30 is held by the user, the bow and arrow are essentially supported by two hands of the user. Such a two-hand support is very stable. However, when the user releases the bow string guide assembly 30 to launch the arrow, one hand of the user is released from the bow string guide assembly 30, and during launching of the arrow, the bow and arrow apparatus is supported by only one hand of the user. Such a one-handed support of the bow and arrow apparatus during launch of the arrow can result in unstable launch conditions which can impede accuracy. In this respect, it would be desirable if a bow-attached, arrow launching apparatus were provided which permits an arrow to be launched while the bow and arrow are supported by two hands of the user.

In U.S. Pat. No. 5,769,065, when the bow string guide assembly 30 is pulled back to tension the bow string, as long as the user takes aim before launching the arrow, the user must maintain full tension on the bow string. This may be fatiguing, especially if a relatively long period of time is needed to take a careful aim. In this respect, it would be desirable if a bow-attached, arrow launching apparatus were provided which enabled a bow string guide assembly 30 to be held in a string-tensed position without the need for a user to maintain full tension on the bow string.

In U.S. Pat. No. 5,769,065, the launcher assembly has front telescopic segments 33 and rear-end guide track assemblies 68. To avoid any possible translation between the front and rear telescopic members, it would be desirable if front guide members and rear guide members were provided which are connected together in a rigid, non-telescopic manner. In this respect, it would be desirable if assembly of front guide members and rear guide members from a storage condition could be carried out rapidly and securely. In this respect, it would also be desirable if disassembly of front guide members and rear guide members from an in-use condition to a storage condition could be carried out rapidly.

In addition to the desirable features mentioned above provided by U.S. Pat. No. 5,769,065 and by U.S. Pat. No. 5,520,163, the present improvement provides the following additional desirable features: (1) permits an arrow to be launched while the bow and arrow are supported by two hands of the user; (2) enables a bow string guide assembly to be held in a string-tensed position without the need for a user to maintain full tension on the bow string; (3) provides front guide members and rear guide members which are connected together in a rigid, non-telescopic manner; (4) permits assembly of front guide members and rear guide members from a storage condition to be carried out rapidly and securely; and (5) permits disassembly of front guide members and rear guide members from an in-use condition to a storage condition to be carried out rapidly. The foregoing desired characteristics are provided by the unique bow-attached, arrow launching apparatus of the present invention as will be made apparent from the following description thereof. Other advantages of the present invention over the prior art also will be rendered evident.

Preferably, the carriage block hold and release assembly means include a carriage block hold and release assembly 52 mounted on the guide member assembly and include a carriage holding element reception portion 68 present on the carriage block 28 . The carriage holding element reception portion 68 can be in the form of a carriage holding element reception channel 68 in the carriage block 28 . The guide member assembly includes a first guide member unit and a second guide member unit, and each respective guide member unit includes a block holding element entry/exit passageway 66 .

Preferably, the carriage block hold and release assembly 52 includes a pair of block holding element stops 62 received in the respective guide member units, positioned distal to the block holding element entry/exit passageways 66 . A pair of block holding elements 64 are placed adjacent to block holding element entry/exit passageways 66 within the guide member units. A pair of plunger wedges 60 are received in the guide member units, and the plunger wedges 60 are positioned proximal to the block holding element entry/exit passageways 66 . A thumb plate 54 is connected to ends of the plunger wedges 60 , and the thumb plate 54 is positioned outside the guide member units. A finger hold 80 is connected to the guide member units in proximity of the thumb plate 54 . Plunger puller springs 58 are positioned between the thumb plate 54 and the guide member units, providing a spring bias for pulling the plunger wedges 60 in a direction away from the block holding element stops 62 . A bridging and carriage stop member 82 is connected to the guide member units between the finger hold 80 and the block holding element entry/exit passageways 66 . The carriage stop member 82 limits backward motion of the carriage block 28 along the guide member units. A pair of block holding elements 64 are positioned between the block holding element stops 62 and the plunger wedges 60 adjacent to the block holding element entry/exit passageways 66 .

In addition, holding-element-retainer magnets 83 are located in the block holding element stops 62 adjacent to the block holding elements 64 for attracting the block holding elements 64 thereto and for holding the block holding elements 64 against the holding-element-retainer magnets 83 .

Preferably, the carriage block 28 includes guide-member-reception channels 88 for receiving the guide member assembly. A magnet-reception well 86 is provided in the carriage block 28 , and a magnet member 84 is received in the magnet-reception well 86 . A bow-string channel gate pin 72 is provided for retaining a bow string 50 in the bow-string-reception channel 70 . First lock pin reception channels 76 are present in the carriage block 28 , and a second lock pin reception channel 78 is present in the bow-string channel gate pin 72 . A gate lock pin 74 is received in the first lock pin reception channels 76 and the second lock pin reception channel 78 for retaining the bow-string channel gate pin 72 in the carriage block 28 .

Turning to FIGS. 9 and 10 , the arrow launching apparatus 10 also includes an arrow 13 especially adapted for use with the arrow launching apparatus 10 . In this respect, an arrow apparatus includes an arrow shaft 21 which includes a front shaft end 11 and a rear shaft end 14 . A front arrow shaft insert 23 is received in the front shaft end 11 , and a rear arrow shaft insert 15 received in the rear shaft end 14 . A screw-in arrow point 27 is received in the front arrow shaft insert 23 , and a magnetic screw-in rear end 29 is received in the rear arrow shaft insert 15 . A front bushing 25 is sandwiched between the screw-in arrow point 27 and the front arrow shaft insert 23 , and the front bushing 25 has an outer diameter which is greater than the outer diameter of the screw-in arrow point 27 , the front arrow shaft insert 23 , and the arrow shaft 21 . A rear bushing 16 is sandwiched between the magnetic screw-in rear end 29 and the rear arrow shaft insert 15 , and the rear bushing 16 has an outer diameter which is greater than the outer diameter of the magnetic screw-in rear end 29 , the rear arrow shaft insert 15 , and the arrow shaft 21 .

The front bushing 25 and the rear bushing 16 are preferably made of relatively low friction material and flexible material. For example, the front bushing 25 and the rear bushing 16 can be made from TEFLON(™) material. When the front bushing 25 is squeezed between the screw-in arrow point 27 and the front arrow shaft insert 23 , the outer diameter of the front bushing 25 is increased. Similarly, when the rear bushing 16 is squeezed between the magnetic screw-in rear end 29 and the rear arrow shaft insert 15 , the outer diameter of the rear bushing 16 is increased.

Because the respective outer diameters of the front bushing 25 and the rear bushing 16 are larger than the outer diameters of other arrow elements, when the arrow 13 is placed in the launcher assembly, the arrow 13 is supported on the launcher assembly by only two points, the front bushing 25 and the rear bushing 16 . As a result, the arrow 13 can move along the launcher assembly relatively rapidly with substantially reduced friction.

To use the embodiment of the invention shown in the drawings, a position on the bow handle 32 is selected, and the bow-handle-received fastener 46 is inserted in a selected bow-handle-fastener reception channel 48 and fastened to the bow handle 32 . Then, the threaded studs 24 of the guide track front assembly are inserted though the threaded stud reception and adjustment slots 44 on the mounting bar 22 . Positions along the longitudinal axis of the mounting bar 22 are selected, and the guide track front assembly is secured to the mounting bar 22 by tightening thumb nuts 20 and locking nuts 26 on opposite sides of the mounting bar 22 . Washers 17 can be located between the thumb nuts 20 and the mounting bar 22 .

When the arrow launching apparatus 10 of the invention is not needed, the guide track front assembly can be mounted on the bow handle 32 without mounting the guide track rear extension assembly to the guide track front assembly. The guide track front assembly can be retained on a mounting bracket on the bow handle 32 or on a quiver mounted on the bow handle 32 until it is needed.

When the arrow launching apparatus 10 of the invention is to be used, the guide track rear extension assembly is removed from the bow handle 32 , and the bow string 50 must be positioned in the carriage block 28 . To do so, the gate lock pin 74 is removed from the first lock pin reception channels 76 and the second lock pin reception channel 78 , and the bow-string channel gate pin 72 is lifted out from the bow-string-reception channel 70 at the rear of the carriage block 28 . Then, the carriage block 28 is moved toward the bow string 50 so that the bow string 50 enters the bow-string-reception channel 70 . Then, the bow-string channel gate pin 72 is replaced in the carriage block 28 , and the gate lock pin 74 is threaded back through the first lock pin reception channels 76 and the second lock pin reception channel 78 . In this way, the bow-string-reception channel 70 surrounds the bow string 50 and permits free movement of the bow string 50 through the carriage block 28 .

Then, the carriage block 28 is mounted on the guide track rear extension assembly by threading the guide-member-reception channels 88 over the rear guide members 36 so that the bow string 50 is at the rear of the carriage block 28 .

Then, the guide member longitudinal inserts 38 are inserted into the first front guide member 34 and the second front guide member 35 . In this way, the free ends of the first and second front guide members 34 , 35 are placed flush against the free ends of the rear guide members 36 , so that the front guide members 34 , 35 and the rear guide members 36 form a smooth, continuous guide track. Then, the respective front guide member set screws 40 are accessed through the respective front set screw access openings 42 , and the front guide member set screws 40 are tightened. The front guide member set screws 40 can have Allen heads, and an Allen wrench can be used to tighten the front guide member set screws 40 . Once the front guide member set screws 40 are tightened, the guide track front assembly and the guide track rear extension assembly are secured together to provide a fully assembled arrow launching apparatus 10 of the invention.

To use the arrow launching apparatus 10 to launch an arrow 13 , the user holds the bow handle 32 with a first hand. With the second hand, the user places an arrow 13 on the guide member units and places the magnetic rear end 29 of the arrow 13 next to the magnet member 84 in the carriage block 28 . As a result, the two magnets attract each other, and the arrow 13 is magnetically attached to the carriage block 28 . Such a magnetic attachment between the arrow 13 and the carriage block 28 keeps the arrow 13 is proper alignment on the arrow launching apparatus 10 and removes the time-consuming need for an arrow notch (or nock) to receive the bow string 50 . In this respect, using the arrow 13 and the carriage block 28 speeds up the step of mounting the arrow 13 in the arrow launching apparatus 10 .

Once the arrow 13 and the carriage block 28 are magnetically joined, with the second hand, the user grasps the carriage block 28 and pulls the carriage block 28 back towards the user. As this occurs, the bow string 50 is being tensed, the arrow 13 and the carriage block 28 are pulled back towards the user as the guide-member-reception channels 88 ride along the front and rear guide members, and the bow string 50 slides freely in the bow-string-reception channel 70 of the carriage block 28 . When the carriage block 28 reaches the bridging and carriage stop member 82 , the carriage block hold and release assembly 52 can be used.

More specifically, when the carriage block 28 is pulled back to reach the bridging and carriage stop member 82 , the block holding elements 64 are in registration with the block holding element entry/exit passageways 66 in the rear guide members 36 . Then, with the thumb of the second hand, the user presses the thumb plate 54 toward the block holding elements 64 , as shown by arrow 12 in FIG. 5 . When this occurs, the bias of plunger puller springs 58 is overcome, the plunger wedges 60 are pushed in the direction of arrow 12 , and the wedge ends of the plunger wedges 60 push the block holding elements 64 through the block holding element entry/exit passageways 66 to contact the carriage holding element reception portion 68 in the carriage block 28 . When this is done, the carriage block 28 and the bow string 50 are held by the carriage block hold and release assembly 52 .

The user can place two fingers of the second hand on the finger hold 80 and have one's thumb on the thumb plate 54 to facilitate applying pressure in the direction of arrow 12 to continue to hold the carriage block 28 by the block holding elements 64 . The amount of strength and effort to hold the carriage block 28 and the bow string 50 with the carriage block hold and release assembly 52 is much less than the strength and effort required to keep the carriage block 28 and the bow string 50 is a tensed position if the carriage block hold and release assembly 52 were not present.

With the user holding the bow handle 32 with the first hand, with the user holding the finger hold 80 and the thumb plate 54 with the second hand, with the carriage block hold and release assembly 52 in-use for holding the carriage block 28 , with the arrow 13 and the bow string 50 in a ready-to-shoot condition, and with the user pressing the thumb plate 54 inward with the second hand, the user takes aim on a target.

When the user is ready to shoot the arrow 13 , with the target in aim, the user carefully lifts one's thumb of the second hand in a direction away from the thumb plate 54 , as shown by directional arrow 19 in FIG. 6 , while still holding the finger hold 80 with fingers of the second hand. As a result, the bow and arrow 13 and the arrow launching apparatus 10 are supported by both the first and second hands as the plunger puller springs 58 pull back on the plunger wedges 60 , permitting the carriage block 28 under tension from the bow string 50 , to move forward, pushing the block holding elements 64 back through the block holding element entry/exit passageways 66 and permitting the carriage block 28 to slide forward under tension of the bow string 50 . In this way, the arrow 13 is propelled forward along the guide member units. When the carriage block 28 reaches the distal end bridging and carriage stopping member 30 , the carriage block 28 is stopped from further forward movement, and the arrow 13 is launched off of the arrow launching apparatus 10 of the invention. At launching of the arrow 13 , the relatively small attractive force between the magnetic rear end of the arrow 13 and the magnet member 84 of the carriage block 28 is easily overcome by the momentum of the arrow 13 rapidly moving along the arrow launching apparatus 10 when the carriage block 28 is stopped.

When the arrow launching apparatus 10 is no longer needed, the arrow launching apparatus 10 is disassembled, and the disassembled apparatus can be stored on a mounting bracket on the bow handle 32 or on a quiver mounted on the bow handle 32 until it is needed again.

The first front guide member 34 , the second front guide member 35 , and the rear guide members 36 can be made from metal tubes, such as ⅜ inch diameter tubes.

The arrow launching apparatus 10 of the invention can be made in any convenient length. Preferably, the guide member units are longer than 30 inches so that the apparatus can be used for launching arrows up to 30 inches long. Moreover, the arrow launching apparatus 10 permits launching of short arrows, that is arrows that are shorter than the distance between the bow handle 32 and the tensed bow string 50 . In this respect, the arrow launching apparatus 10 can be used with arrows that are 7 inches and 10 inches long.

In general, the components of the bow-attached, arrow launching apparatus of the invention can be made from inexpensive and durable metal and plastic materials.

As to the manner of usage and operation of the instant invention, the same is apparent from the above disclosure, and accordingly, no further discussion relative to the manner of usage and operation need be provided.

It is apparent from the above that the present invention accomplishes all of the objects set forth by providing a new and improved bow-attached, arrow launching apparatus that is low in cost, relatively simple in design and operation, and which may advantageously be used to permit an arrow to be launched while the bow and arrow are supported by two hands of the user. With the invention, a bow-attached, arrow launching apparatus is provided which enables a bow string guide assembly to be held in a string-tensed position without the need for a user to maintain full tension on the bow string. With the invention, a bow-attached, arrow launching apparatus provides front guide members and rear guide members which are connected together in a rigid, non-telescopic manner. With the invention, a bow-attached, arrow launching apparatus is provided which permits assembly of front guide members and rear guide members from a storage condition to be carried out rapidly and securely. With the invention, a bow-attached, arrow launching apparatus is provided which permits disassembly of front guide members and rear guide members from an in-use condition to a storage condition to be carried out rapidly.

Thus, while the present invention has been shown in the drawings and fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment(s) of the invention, it will be apparent to those of ordinary skill in the art that many modifications thereof may be made without departing from the principles and concepts set forth herein, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use.
