DESCRIPTION

[0027] Connector for Connecting a Firearm to a Bipod

[0028] A connector 10 in accordance with the invention is shown in FIG. 1, connecting a bipod 12 (an example of an object in the context of the invention) to a hunting rifle 14 (an example of an article of equipment in the context of the invention). A tripod could be used as the object instead of a bipod. The connector 10 includes a steel base 16 component which is fixed to the lower surface 17 of the wooden fore-end 18 of the rifle 14 by screws (omitted for clarity) which pass through holes 20, 21 in the base 16 into the fore-end. For military rifles and other firearms having an accessory mounting system on the fore-end such as, for example, a Picatinny, STANAG 4694 NATO accessory rail, Weaver rail or similar, the base 16 of the connector base may be fixed to the accessory mounting system, by clamping, bolting or as otherwise appropriate to the system, rather than directly to the material of the fore-end. In other cases, the connector base is formed integral with the article.

[0029] It will be noted that the legs 24, 25 of the bipod 12 extend forwardly, from a bipod head joint 13, which hingedly connects the legs 24, 25 under the barrel 26 of the rifle in the folded configuration shown in FIG. 1.

[0030] The connector 10 further comprises an aluminium locking slide 28 having a substantially flat rear face 30 and a curved forward face 32. The locking slide 28 is substantially in the form of a barrel. The locking slide 28 is shown in a rearward locking position in FIG. 1. The locking slide can be slid in the direction of arrow A (i.e parallel with the main longitudinal access of the firearm) by a user into a forward unlocked, or disengaged, position (shown in dotted outline in FIG. 1) by user pressure on the rear face 30. Typically, a user may press with their thumb on the rear face 30 to move the locking slide 28 forward to allow normal engagement or disengagement of the bipod. An average righthanded user using the connector 10 in conjunction with an article of equipment such as a firearm may conveniently grip the locking slide between the thumb and forefinger of their left hand and push the locking slide forward whilst holding the firearm with their right hand, i.e., whilst still maintaining control of the firearm.

[0031] The connector 10 is shown in cross-section in FIG. 2. It can be seen that the bipod head joint 13 includes an integral projection 33 (forming the projection in the context of the invention) which is received within a generally cylindrical recess 34 defined by the base 16. The projection 33, which is generally cylindrical, optionally includes a rare earth magnet 44 fixed to the upper end of the projection. The magnet 44 may be glued in position or otherwise held, for example, by a screw passing through an aperture in the magnet 44 into the projection 33. It will be appreciated that the magnet 44 can be omitted from the connector in some embodiments.

[0032] A ball detent 35 is located in a forward portion of the locking slide 28 and extends through an aperture in the forward wall of the recesses 34, where it bears against the outer surface of the projection 33, when the projection is inserted in the recess 34 and the locking slide is in the rearward locking position.

[0033] A spring 36 is located between the locking slide and a portion of the base 16 forming the rear of the recess 34 so that the spring is compressed when the rear face 30 is pressed by a user moving the locking slide 28 into the forward unlocked position.

[0034] When the locking slide is so moved into the forward unlocking position, the ball detent 35 is moved away from the surface of the projection 33.

[0035] The generally cylindrical profile of the projection 33, around a longitudinal axis X (shown in FIG. 3A) extending via a narrower cylindrical neck 37 from the bipod joint 13 is shown in more detail in FIG. 3A and FIG. 3B and FIG. 4. The projection 33 is shown in FIG. 3A in elevation when the orientation of the bipod is in the position shown in FIG. 2. A narrow vertical groove 38 extends vertically on the facing surface of the projection 33 for receiving the ball detent. As shown in the plan view of FIG. 4 two more further narrow vertical grooves 40, 41 are formed in the surface of the projection 33 at 90 degrees of rotation about the axis X from the narrow groove 38. A wider groove 42 is formed on the opposite surface of the projection 33. The lower edge of the projection 33 and the narrower neck 37 form a rim 43.

[0036] The locking slide 28 is shown in more detail in FIG. 5, which shows it isolated from the other elements of the connector 10 for clarity. The locking slide 28 forms a generally D-shaped aperture 29, which has a substantially straight forward edge 31. A rear aperture 27 receives the spring 36.

[0037] The locking slide 28 moves generally horizontally, transversely to the longitudinal axis X of the projection, parallel with the main longitudinal axis of the firearm. More particularly, the locking slide moves perpendicularly to the projection.

[0038] In use, a user generally has to move the locking slide 28 of the connector 10 to the forward unlocked position against the action of the spring 36 before the projection 33 can be inserted into the recess 34. An exception to this is when the wider groove 42 on one side of the projection 33 is aligned with the front of the recess 34. In that axial orientation the wider groove 42 is aligned with the straight front edge 31 of the locking slide 28, and the projection 33 can be inserted into the recess without the locking slide being activated. In either case, the magnet 44 (where present) is attracted to the steel base 16, which facilitates insertion of the projection 33 into the recess 34 and inhibits the bipod from being accidentally detached from the connector. Release of the locking slide 28 by user allows the locking slide 28 to move rearwardly under the action of the spring 36, so that the lower forward edge of the slide, around the edge 31, engages under the forward edge of the rim 43 holding the projection and connected bipod 12 securely to the rifle. Therefore, in order to remove the bipod from the connected rifle, a user has to move the locking slide forwardly into the unlocked position so that the lower edge of the slide 28 no longer engages the forward edge of the rim 43. The projection can then be removed from the recess 34 by pulling to overcome the attraction between the magnet 44 (where present) and the ferrous base 16. The only exception is in the above situation is where the wider longitudinal groove 42 is aligned with the front of the recess 34. In that axial orientation the wider groove 42 is aligned with the straight front edge 31 of the locking slide 28, and the projection 33 can be withdrawn from the recess, when the attraction between the magnet 44 and the base 16 is overcome (where the magnet is present) without the locking slide 28 being activated. This provides an advantageous quick detachment orientation/facility.

[0039] The connector 10 allows the connected bipod 12 to rotate freely about the longitudinal axis of the projection through 360 degrees. The ball detent 35 holds the projection in different axial orientations through engagement with the grooves. Engagement of the ball detent with the opposed narrow grooves 40, and 41 holds the bipod in the forward-pointing folded condition shown in FIGS. 1 to 3, or, as the case may be, a rearward-pointing folded condition in which the legs 24, 25 extend rearwardly depending on the groove 40, 41 engaged by the ball detent. When the ball detent is in the narrow groove 38, and the bipod joint is operated so that the legs 24, 25 are moved to a downwardly depending and splayed active position the rifle is held in a generally forward-facing position and the bipod does not freely rotate. This is advantageous in a target shooting situation, where a rifle does not need to be panned. Alternatively, when the ball detent is in the wide groove 41, the projection is free to rotate between the extremes of engagement of the ball detent with either side of the wide groove 42. In this manner, when the legs 24, 25 are in a downwardly depending and splayed active position the rifle can be panned between the limits imposed by the engagement of the ball detent with the vertical edges of the wide groove 42, whilst still being supported by the bipod. This is advantageous in a hunting situation. It should be noted that the ball detent 35 permits rotation of the projection through 360 degrees when overcome by a user.

[0040] From the above it can be seen that the bipod 12 can be quickly connected to the rifle 14 by inserting the projection 33 into the recess 34 formed by the base, either by aligning the wider groove 42 with the straight front edge 31 of the locking slide 28 so that the projection 33 can be passed though into the recess 34, or by retracting the locking slide 28 so that the projection 33 can be inserted into the recess 34 in any axial orientation. Once the projection is inserted into the recess it can be rotated about its longitudinal axis which engages the locking slide 28 with the rim 43 of the projection but permits further rotation of the bipod into different axial orientations. The bipod is thus held securely by the connector in the normal downwardly depending legs active position, typically used when shooting the rifle, and can only be detached from the rifle by operating the locking slide 28. Furthermore, the bipod is securely held by the connector 10 when the legs of the bipod are in either a forward-pointing or a rearward-pointing folded position, typically used when the rifle 14 is being carried by a user and cannot be removed from the rifle without operating the locking slide. The ball detent retains the bipod in the different axial orientations.

[0041] Connector for Connecting an Optical Device to a Tripod

[0042] By way of example of another article of equipment, an optical device such as a camera may be connected to a tripod by such a connector as described above with simple changes. One such connector 50 for an optical device is shown in FIGS. 6 and 7. The connector 50 is formed generally as described above in relation to connector 10, with a slidable aluminium locking slide 51, which can be moved against resilient biassing means provided by a spring as described above. In use, the connector recess 60 receives a projection 52 which is integral with a ball head 54 for a conventional ball tripod (not shown). A steel bolt 56 extends through steel base 58 for fitting to the screw mount on the base of a camera or large telephoto lens. Most consumer cameras are fitted with 1/4-20 UNC threads. Typically, professional cameras and lenses may be fitted with 3/8-16 UNC threads. The bolt 56 is correspondingly threaded to match the screw mount according to the intended use. In this way, the connector 50 can be firmly attached to the screw mount on the base of a camera by means of the bolt 56. The connected camera and connector can be rapidly and securely connected to the projection 52 on a ball head tripod (not shown) by operating the locking slide 51 or pushing the projection 52 into the recess so that it operates the slide 51. A ball detent engages a corresponding depression defined by the surface of the projection. The projection 52 can be released from the connector 50 by operating the slide 51. One of the projection or the bolt may be provided with a magnet to facilitate connection of the projection to the connector. It will be noted that a user standing normally behind a tripod to use the camera will push the slide 51 generally horizontally to release the projection unless the projection is in an axial orientation which permits removal of the projection without operation of the locking means. This is convenient to do in practice as the user is in the same stance for operation of the connector slide as for operation of the camera.

[0043] Connection of a Phone to a Bicycle

[0044] By way of example of another article of equipment, a mobile phone may be connected to a bicycle or motorbike, by such a connector as described above with simple changes. The base of the connector having the recess could be provided in the form of an adaptor fitted to the mobile phone which receives a similar projection provided by, or in the form of a further adaptor fitted to, the bicycle stem or handlebars. The slidable locking slide can be moved by the user in a direction generally parallel with the main longitudinal axis of the handlebars or stem to release the projection (and the connected phone) from the recess.
