Top ring relief joint for a horse bridle bit and method of use

Abstract

The disclosure of the present invention relates to a HORSE BRIDLE BIT or more specifically to a horse bridle bit having a mouthpiece and independently movable shanks connected using a pinch-free ball joint assembly and the shank top ring having a relief joint to reduce contact pressure to the horses jaw when the bit shank is manipulated laterally. The bit configured to convey clear communication to the horse without undue encroachment in the mouth or jaw.

Claims

DETAILED DESCRIPTION OF DRAWINGS

(8) For the purposes of promoting an understanding of the principles in accordance with the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the disclosure as illustrated herein, which would normally occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the disclosure claimed.

(9) In describing and claiming the present disclosure, the following terminology will be used in accordance with the definitions set out below. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. As used herein, the terms “comprising,” “including,” “containing,” “characterized by,” “having,” and grammatical equivalents thereof are inclusive or open-ended terms that do not exclude additional, unrecited elements or method steps.

(10) The present invention will be described more fully hereinafter with reference to the accompanying drawings, which illustrate embodiments of the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the illustrated embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

(11) A first embodiment of the present invention or horse bridle bit 100, shown in FIGS. 1 and 2, including side shanks 110 having an articulating mouthpiece 120 attached using a moveable joint 115. The side shanks 110, including a shank portion 111 and a purchase portion 112 offset from the shank portion 111 by approximately 45 degrees. The side shanks 110 also having a defined inside surface 113 and outside surface 114. Moveable joint 115 is formed at the offset junction between the shank portion 111 and the purchase portion 112. Moveable joint 115 including a spherical pin 116, having attachment pins 117; side bar 121 of mouthpiece 120 including an end ring 122 configured to encompass the spherical pin 116. The moveable joint assembly 115 is fitted into a joint cutout 118 formed in the side shanks 110. The joint cutout 118 having a generally circular shape to accommodate spherical pin 116 and having semi-circular ring cut-outs 1181 formed along the equatorial axis of the spherical pin 116 configured to accommodate the end ring 122. The joint cutout 118 also including pockets configured to receive the attachment pins 117 which are pressed, soldered, welded or otherwise attached to the side shanks 110. Joint cutout 118 has a tapered profile through the side shank 110 with a narrow tolerance formed on the inside surface 113 of side shank 110 and more open tolerances formed at the outside surface 114 in relationship to the moving parts of moveable joint 115. The narrow tolerances at the inside surface 113 prevent the joint from pinching the skin on the horse's lip. Generally moveable joint 115 is configured to allow for a tilting articulation of the mouthpiece side bar 121 away from a position perpendicular to the plane formed by an X axis through the equator of the spherical pin 116, and along the main longitudinal axis of the purchase portion 112 of the side shank 110, and a Y axis corresponding to the vertical axis formed by the attachment pins 117. The spherical pin 116 and end ring 122 engagement fully prevents the mouthpiece side bar 121 from pulling away from the side shank 110 or out of the plane formed by the X and Y axis along a third Z axis. The open tolerances between the side shank 110 at the outside surface 114 allows for greater tilting articulation of the mouthpiece side bar 121 in an axis perpendicular to the longitudinal axis of the side shank 110. Changing the outside tolerances of the joint cutout 118 allows for modification of the bit characteristics; a more open tolerance allows for a “free floating” mouthpiece 120 whereas, when the tolerances are narrowed, the side bar 121 will move readily, reflecting any subtle motion imparted by the reins to the side shank 110. Rotation downward of the side shank 110 around the Z axis creates a corresponding rotation of the mouthpiece side bar 121; end ring 122 is configured to engage the surface of the ring cutout 1181 and will impart any rotational movement of the side shank 110 into the side bar 121 of the mouthpiece 120.

(12) Mouthpiece 120 includes side bar 121, having ring ends 122 and a central link or port 123. It is contemplated that mouthpiece 120 may also be a single bar bit or a single bar including one or more offset portions or shapes.

(13) The free end of the shank portion 111 including a rein ring 119 and the free end of the purchase portion 112 including a top ring 130. In one embodiment there may be a single top ring, however, in another embodiment the top ring 130 may include an upper headstall ring 131 and a lower curb ring 132 for installation of a curb strap or chain. In yet another embodiment of the present invention, the top ring portion 130 is articulated using a relief joint 133 attached within a limit slot 134 formed in the purchase portion 112 of side shank 110. The relief joint 133 configured prevent the top ring 130 portion of the bit 100 from encroaching on the back of the horse's jaw, when the bit is aggressively manipulated during a turn.

(14) The bridle bit 100 shown in FIGS. 3 and 4 is installed in horse mouth, including side shank 110 having a rein ring 119 and top ring 130. Reins 210 are installed at 119 and a headstall 230 and curb strap 220 are installed at top ring 130.

(15) FIG. 3 is included to indicate that as reins 210 are pulled as in a whoa command, the end of the side shank 110 will move down and back creating a rotation at moveable joint 115. This rotation will be translated to the side bar 121 of the mouthpiece 120 and a cause a port 123 in the mouthpiece to stand, signaling the horse to whoa or to stop (see FIG. 1).

(16) FIG. 4 indicates that as the reins 210 are pulled back and away from the horse's head, as in an aggressive turn, the rein end of side shank 110 will be pulled away, and the top ring 130 will be pressed in, toward the back of the horse's jaw, however, top ring 130 will give along relief joint 133 to prevent the top ring 130 from encroaching on the side of the horses jaw and teeth.

(17) FIGS. 5A and 5B are a top view of one embodiment of the horse bridle bit side shank 110 having an inside surface 113 and outside surface 114, a moveable joint 115 and head ring 130. The moveable joint 115 including, spherical pin 116 and the side bar 121 with end ring 122. The end ring 122 having one or more control stops 125 configured to engage the outside surface 114 of the side shank 110 and to limit the motion of the mouthpiece side bars 121. The position of the stops 125 can be adjusted to change the response of the bit for a particular rider, riding style, discipline or horse. FIG. 5B shows the how top ring 130 can rotate around relief joint 133 to alleviate pressure by the top ring 130 on the back of the horse's jaw. The size of limit slot 134 is configured to hold the top ring 130 in line with side shank 110 but can be can also be adjusted depending on the desired overall deflection or relief angle T. The angle of the relief joint 133 and the size of the limit slot 134 can also be modified to correct the head position of a particular horse, for example when a horse drops their head to low, or over flexes their neck, during a turn, the angle of relief joint 133 and the size of limit slot 134 can be reduced and the horse will not be afforded as much relief unless their head is held higher or in a proper position.
