(22) While the invention is amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not necessarily to limit the invention to the particular embodiments, aspects and features described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention and as defined by the appended claims.
DETAILED DESCRIPTION OF THE INVENTION
(23) Referring to
(24) At an upper portion 28 of handle 24 or of grip 22, or on top of grip 22 is positioned a base 30 having an upward extending arm 34. Arm 34 extends from base 30 at a first side 33 of device 20. A finger 40 or fingers 40a, 40b are positioned opposite arm 34 at a second side 35. In one aspect arm 34 includes a smooth concaved surface spanning to a head portion 36. The smooth concaved top surface 38 is configured to receive at least a part of a camera or firearm to be supported by device 20 and a corresponding stick 51 or sticks. The head portion 36 projects generally upward from arm 34. The finger 40 or fingers 40a, 40b extend generally outward from base 30. In one aspect, fingers 40 are oriented generally perpendicularly to head portion 36.
(25) As shown in
(26) In further reference to
(27) In operation device 20 and/or handle 24 accommodates quick-connect and quick-release connection of sticks 51, 52 to form a shooting bipod 60. With reference to
(28) As shown in
(29) With reference to
(30) With reference to
(31) With reference to
(32) As shown in
(33) In further aspects, housing 105 is made of a first receiver casing 101 connected to a second receiver casing 103. Each casing 101, 103 includes a portion of core 107 such that when combined the complete core 107 is provides. Fasteners having lock heads and nuts are used to secure the first receiver casing 101 to the second receiver casing 103. Countersunk openings receive the head of fasteners and nuts to provide a smooth user-friendly finish and ease of assembly. Housing 105 is symmetrical about a central plane P-P passing through a center hole 117 as shown in
(34) Receiver 100 is firmly secured to a frame 112 of backpack 102 by use of frame mount 110. Frame mount 110 includes cooperating brackets 114, 116 which wrap about frame 112 and secure together with fasteners such as bolts 118, nuts 119, screws or other fasteners. A bolt 118 is also provided through mount 110 and through a hole in frame 112 and secured with nut 119. In one aspect bolt 118 has a head which is received in a holder defined by bracket 116 for convenient holding of bolt 118 from spinning during threading of bolt 119. Bolt 118 also passes through a center hole 117 running through receiver 100. Bracket 116 defines a curve 115 configured to receive a portion of frame 112 to accommodate wrap-around of frame mount 110 about frame 112, for instance. Bracket 114 has a similar or corresponding curve to also accommodate placement and firm securing to frame 112.
(35) Bracket 114 includes teeth 120 which mesh with like teeth 120 contained within respective receiver casings 101, 103 of receiver 110. Receiver casings 101, 103 join together with bolts or other fasteners to form housing 105 and in part define gap 108. Bolts, nuts or other fasteners are countersunk into countersink holes formed in receiver 100 and frame mount 110. Housing 105 may be adjusted to secure to frame mount 110 at different angles by rotating receiver casing 103 about bracket 114 so that housing 105 is situated within bracket teeth at a new orientation. Thus, the inserted stick 51 may project from the frame 112 or object at a different angle, which may be easily adjusted by loosening of nut 119 and readjustment of housing 105 about bracket 114.
(36) Receiver 100 is configured for attachment to frame 12 at various locations on backpack 102 (or upon other object) and may be used symmetrically such that either upside or downside is identical so that receiver 100 may be mounted on either a right side or left side or other side of backpack 102. As shown in
(37) Device 20 allows a user to achieve multiple functions for sticks 51, 52, such as for connection to form a shooting bipod, tripod, or component for weight assist of objects such as backpacks. A further aspect of the invention includes sticks 51, 52 comprising the device 20. Yet further aspects of the invention include a shooting bipod comprising a first stick 51 and a second stick 52 each equipped with the attachment device 20 and a quick release pin 44 positioned through the through holes 42. A further aspect of the invention includes a tripod utilizing the bipod as described where the quick-release pin 44 is connected to a third stick 53. Yet a further aspect of the invention includes the bipod 60 or the tripod 70 including a cap 72 configured to receive an accessory. In one aspect the invention includes device 20 configured to screw into a threaded receiver positioned at a top of a stick which may include insertion into a grip or handle of a stick or pole. Thus, device 20 may be removed from a stick as desired for use on a different stick. Alternatively, device 20 is connected (and alternatively integrally connected) to a grip or a handle which grip or handle in turn is attached (and/or removable) from various sticks.
(38) In one aspect device 20 (including cap 72) and receiver 100 are made using hardened plastic and molded into the desired configuration. A variety of different materials may also be used. In a further example grip 22, base 30, arm 34 and fingers 40 are integrally connected, and in a further aspect are made using a hardened nylon reinforced with fiberglass. A variety of polymers may also be used for the materials used to create device 20 (and cap 72) and receiver 100, including hardened PVC or other plastics. Pin holder 45 may be comprised of an inserted metal piece configured to receive the pin 44 for storage. The inserted metal piece may be molded in place during production. Shaft 50 (and also receiver 100) may be made from a variety of different materials, including metal (such as aluminum or other metal), carbon fibers, wood, plastics, or a variety of alloys and/or combinations. Shaft 50 is of a telescoping or collapsible variety and may include joints which twist and lock shaft segments to a desired position or length for easy adjustment. Camera mount 80 may include a standard camera mount configured to attach and swivel to traditional tri-pod devices. A camera or other device may be connected to mount 80 as desired.
(39) It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
