Description

Rein Safety Connector Device

Field to the Invention

The present invention relates to a safety device for a pair of reins and in particular a connector device that permits a pair of reins to break when subject to certain force.

Background of the Invention

When horse, ponies, donkeys and other animals are ridden they are typically provided with a bridle and reins. The reins connect to a bit which is attached to the bridle, or in the case of bites bridles to rein attachment points. Reins are typically provided in pairs. Whilst in some styles of riding the rains of the pair are not connected together at their ends remote from the bit, in many styles the individual reins are connected together at their ends remote from the bit. The connection is usually provided by a buckle, or the reins may be stitched together.

One disadvantage of reins that are attached to each other at their ends remote from the bit is that if the reins become caught on an object, a dangerous situation may arise. For example, in the case of a rider falling from a horse it is not uncommon for a limb of the rider to become caught in the reins. This can be extremely dangerous, resulting in the rider being dragged by the horse. It is also known for the reins to become caught around an object. The object may be one that is being passed by the horse and rider, such as a hook on a gate post for example.

In any situation where a force is applied to the reins other than under the control of the rider, there is the potential for a dangerous situation to arise.

It has been proposed to provide a connector for connecting the free ends of the reins of a pair together that permits the reins to separate when the connector is subjected to a certain force.

The problem described above is longstanding and well know. Numerous attempts have been made to provide a connection that will break when subject to a threshold force.

For example, US 6,098,384 describes an inset which attaches to the ends of a standard pair or reins having buckle connector. The insert includes a frangible buckle. If the reins are subject to a threshold force, the frangible buckle will break and the reins come apart.

W02017164870 is another example of an insert positioned between the free ends of a pair of reins which include hook and loop material. When a force is exerted on the reins that is suffi-cient to detach the hook material from the loop material, the connection between the free ends of the reins is broken.

DE202011105589U describes another alternative connector which is designed to release when the reins are subject to a threshold force.

Whilst numerous attempts have been made addressing the problem described above, none of the solutions have been adopted widely. In the case of a frangible buckle, if the buckle is broken, reconnecting the free ends of the reign is not straightforward. The broken part of the buckle must be replaced for example. In general, inserts can change the balance of the reins which may make them undesirable for the rider. The feel of the rein in the riders hands can be affected by adding additional weight to the ends of the reins remote from the bit or connection to the bridle.

It would therefore be desirable to provide an improved releasable connector for connecting together the free ends of a pair of reins.

It would also be desirable to provide a pair of reins including such an improved releasable connector

Detailed Description of the Preferred Embodiments

Referring now to Figures 1 and 2, the safety device 1 of the invention comprises a ball component 2, a socket component 3 and a retaining ring component 4. As can be appreciated from Figures 1 and 2, the ball of the ball component is passed through the ring component 4 and is pushed into the socket component 3.

The ball component is formed as a one piece plastics moulding which comprises a central portion from which extend elongate side members 2b which are connected together by a cross-member 2c at the ends of the elongate side members 2b remote from the central portion 2a. The ball 2d of the ball component 2 is also connected to the central portion 2a by a connector 2e. In use, a free end of one rein of a pair passes around the cross member 2c to fasten the rein to the ball portion 2.

The socket component 3 is also formed as a one piece plastics moulding comprising a socket element 3a from which extend side members 3b. The ends of the side members distal from the socket element 3a are connected together by a cross-member 3c at the ends of the elongate side members 3b. The socket element 3a (which is described in greater detail in Figures 6 to 10) comprises a socket base 3a' and a plurality of socket leaves 3a" and an externally threaded region 3d.

The retaining ring component 4 comprises an internal thread 4a which is configured to cooperate with the external thread 3d of the socket component. The retaining ring 4 is provided with external grip elements provided by depressions 4b formed in the outer surface of the retaining ring 4.

The ball component 2 is illustrated in greater detail in Figures 3 to 5. The central portion 2a comprises an outer wall 2a' having a first depth and a region 2a" that is surrounded by the wall 2a' and which has a depth less than the thickness of wall 2a'. The central portion 2a therefore provides a convenient part to grip when a user is connecting the ball 2d of the ball component 2 to the socket 3a of socket component 3. In the illustrated embodiment, the region 2a" has a diameter of 12mm and the outer wall 2a' has a diameter of 14mm, the wall having a thickness of 1mm.

The wall 2a' adds strength and rigidity to the whole ball component 2 as well as providing a suitably dimensioned element for the connector 2e to extend from. In the illustrated embodiment, the wall has a depth of 7.3mm, whereas the region 2a" has a depth of 3.3mm.

Figures 6 to 10 illustrate the socket component 3 in greater detail. The socket 3a comprises a socket base 3a' in which the ball 2d is received and an open end through which the ball 2d is inserted, the open end defined by a plurality of adjacent socket leaves 3a". The internal diameter of the socket base 3a' has substantially the same diameter as the external diameter of the ball 2d.

In order to attach the ball 2d to the socket 3a the ball 2d is presented up to the open face of the socket 3a. As the outer surface of the ball 2d engages the end faces of the socket the leaves 3a", the socket leaves 3a"are push outward thereby allowing the ball 2d to be pushed into the socket base 3a'. The diameter of the open end of the socket 3a is 12mm as shown in Figure 2. Whereas the diameter of the socket is 13mm. The diameter changes at the plane Y-Y illustrated in Figure 16. When the widest part of the ball 2d moves past the plane Y-Y in the direction Z, the socket leaves 3a" return to their closed configuration, and assist in pushing the ball into the position shown in Figure 16 where the outer surface of ball 2d is in contact with the inner surface 3e of the socket 3a.

Figure 14 illustrates the sequence of assembly of the ring 4 relative to the ball component 2 and the socket component 3. The ball 2d is passed through the ring 4. The internal diameter of the ring 4 is larger than the external diameter of the ball 2, the ring having an internal diameter of 16mm compared to the external diameter of 13mm of the ball 2d, in the illustrated example. After the ball has been pushed into the socket 3a, the ring 4 is presented up to and aligned with the threads 3d of the socket 3a. The ring 4 is then rotated relative to the socket so that the internal threads 4a of the ring engage with the external threads 3d of the socket 3a. The ring 4 is rotated until it is tight relative to the socket 3a.

The components of the safety device 1 are all formed from a polypropylene material, preferably the same polypropylene material. The plastics material from which the components are formed is sufficiently flexible to allow the ball and socket to be pulled apart when sufficient force is applied, without fracturing any components and without deforming any components beyond their elastic limits. In the event that an incident occurs in which the reins become caught on an object, if sufficient force is applied to the safety device 1 pulling the ball 2d out of socket 3a, those components will separate. In most circumstances the disconnection of the ball from the socket will allow the reins to pull free from the object upon which the rein was caught.

In order to reassemble the safety device 1, the ring 4 is rotated such that the threaded region 4a of the ring 4 comes away from the threaded region 3e of the socket 3a. The ring 4 is passed over the ball 2d as described above, and the ball 2d is inserted into the socket 3a. The ring 4 is then tighten onto the socket 3a as described above.

Figure 17 illustrates a bridle 5, including a bit 6, with a rein set 7 attached to the bit 6. The rein set includes a safety device 1 of the type described in Figures 1 to 16, the rein 7a being attached to cross-member Sc and the rein 7b being attached to the cross-member 2c, the respective other ends of reins 7a, 7b being attached to bit rings 6a and 6b respectively.
