Abstract: The invention relates to horse bit (10, 100), comprising a mouthpiece (20, 120) configured to be inserted into a horse's mouth and comprising a first cheek (40, 140) and a second cheek (60, 160). The mouthpiece includes a first end (21, 121) and a second end (22, 122) and a center portion (30, 130) between the first end and the second end, wherein the center portion comprises at least one curved portion (31, 32; 131, 132). Each cheek includes a shank (50, 70; 150, 170) with an upper arm (53, 73; 153, 173) and a lower arm (54, 74; 154, 174) for attachment of reins and a central portion (55, 75; 155, 175) between the upper arm and the lower arm. The central portion of the first cheek is attached to the first end and the central portion of the second cheek is attached to the second end.

Abstract: The invention relates to a horse bit (10, 210) comprising a shackle (20, 220) configured to be inserted into a horse's mouth. The shackle comprises at least one joint (30, 40; 230) and two side portions (50, 60, 250, 260), wherein the two side portions are connected by the at least one joint such that the side portions are pivotable to each other, and at least two eyelet members (80, 90, 100, 110; 280, 290) each having an eyelet bore (82, 92, 102, 112; 282, 292), wherein the eyelet members are interlocked with play via their eyelet bores to provide the at least one joint. Further, in a cross section in the range of one of the eyelet members along or substantially parallel to an axis of the eyelet bore a cross-sectional width (W1, W2) of the one eyelet member is larger than the inner width (W3) of the eyelet bore of the other eyelet member.

Abstract: The invention relates to a horse bit comprising a shackle (20) configured to be inserted into a horse's mouth. The shackle (20) extends along a longitudinal path (A) and has a first end (22) and a second end (24) for attachment of cheeks (120, 130, 140, 150). In a cross-section substantially perpendicular to the longitudinal path (A) the shackle (20) has at least one shackle surface region (30) comprising a linear or a concave surface profile section (32, 34).

Abstract: The invention relates to method for evaluating the quality of characteristics of motion of an animal-human-dyad comprising an animal and a human and using at least one rein for riding the animal, wherein the quality of characteristics of motion is the loss of regularity of rhythm in the motion of the animal, the method comprising obtaining rein tension data indicating the tension in the rein (10) by means of a rein tension measuring device (20), wherein the the following steps are executed by a processing unit (90): processing the rein tension data into a frequency spectrum; identifying a prominent frequency component in the frequency spectrum; analysing the frequency spectrum by determining a power spectral density of the frequency spectrum over a frequency range which contains the prominent frequency component; and evaluating the loss of regularity of rhythm in the motion by comparing the determined power spectral density with a reference value.

Abstract: Equestrian bits are manufactured with the mouthpiece component comprising a copper alloy with composition; 65-80% by weight copper, 0-2% tin and the remainder being zinc including other elements. In a further embodiment, the copper alloy comprises 70-73% copper, 0.9-1.2% tin, 28% zinc the remainder being other elements at a %, by weight, of less than 1%. The alloy of the invention provides a horse bit mouthpiece which rapidly achieves thermal equilibration when placed in, or moved within, the mouth and has characteristic strength sufficient for the intended use.
