Title: Stall Divider

Description:
FIELD OF THE INVENTION 
     The invention relates a stall divider suitable for free stall stables comprising at least one vertical support member, at least one lower member extending away from the support member, at least one upper member extending away from the support member, and at least one crossing member extending perpendicularly to the upper member(s). 
     BACKGROUND OF THE INVENTION 
     Stall dividers today comprise a pivotal neck rail of metal, which can be pivoted up and down; however, this structure is more liable to fail if the cow applies a larger amount of force to it. Furthermore, the rigid structure may hurt the cow when the cow comes in contact with the neck rail. The neck rail also limits the movement when the animal is standing up. Such a stall divider is described in WO 2009/052829 A1. 
     US 2007/0006817 A1 describes a free stall divider comprising a divider member, a support rail mounted on a structural member of the barn, and a control rail suspended from the support rail. The disadvantage is that the control rail is not sufficiently effective to prevent the cow from entering further into the stall. Furthermore, the cow may easily move into the adjacent stall or the opposite stall. 
     Conventional stall dividers, such as described in US 2005/0263092 A1, consist mainly of metal, which reduces the comfort and welfare of the animals since the animals may hurt themselves on the rigid structural elements. Furthermore, the disadvantage with the conventional structures is that the animals may get stuck in the structure, thus reducing the comfort and welfare even more. 
     None of these stall dividers provides a simple and versatile structure that improves the comfort and welfare of the animals. 
     SUMMARY OF THE INVENTION 
     The object of the invention is to improve the comfort and welfare of free ranging cows by providing an improved stall divider having a more versatile and a simpler structure. The structure is also more cost-effective and easier to manufacture and to assemble. 
     The invention solves these problems by providing a stall divider suitable for free stall stables wherein the upper member is secured to the vertical support using a mounting fixture that enables it to be moved up and down on the support member. This enables the stall divider to be adjusted according to different size animals. 
     The crossing member may be made of a bendable or deflectable material. The lower member may as well be made of a bendable or deflectable material. The upper member may also be made of a bendable or deflectable material. This enables the stall divider to bend or deflect to a certain degree when an animal applies pressure to the member, which in turn increases the comfort and welfare of the animals. 
     The crossing member and either the lower member or the upper member may comprise a hollow tube structure. The thickness of the crossing member may be smaller than the thickness of the lower member or the upper member. This enables the stall divider to deflect or bend more when pressure is applied, thus increasing the comfort and welfare of the animals. 
     At least one second lower member, at least one second upper member, and at least one second crossing member may be mounted on the opposite side of the vertical support member. 
     The invention also solves these problems by providing a free stall stable comprising a plurality of stall dividers as disclosed above arranged in one or more rows and/or columns.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  shows an embodiment of the invention. The stall divider may comprise a vertical support member  1  extending down into the ground or the floor of the stable. The vertical support member  1  may alternatively be mounted on a support structure in the ground or floor. The support member  1  may be a hollow or a solid support bar made of a rigid material such as iron, steel, wood, or similar materials. The support bar may have any cross-sectional shape, preferably square or circular. The dimensions of the vertical support member  1  may depend on the intended use of the stall dividers. 
     A lower member  2  may be mounted on the vertical support member  1  near the ground or the floor. One end of the lower member  2  may be secured to the vertical support member  1  at a certain position using a mounting fixture  3 . The mounting fixture  3  may have a construction that enables it to be moved up or down on the support member  1 . The mounting fixture  3  may be attached to the lower member  2  and/or the vertical support member  1  using bolts, screws, or any other type of fastening means. In an alternative embodiment the mounting fixture  3  may comprise a first plate (not shown) connected to the lower member  2  and attached to a second plate (not shown) on the opposite side of the support member  1  via the fastening means. In a second alternative embodiment the mounting fixture  3  may comprise a first plate (not shown) connected to the lower member  2 , and one or more U-shaped fastening means may be connected to the first plate. This enables the lower member to be adjusted according to different size animals. 
     Alternatively, the lower member  2  may be mounted directly on the support member  1  using any type of fastening means or by welding or any similar process. 
     An upper member  4  may be mounted on the vertical support member  1  at the opposite end. The upper member  4  is secured to the vertical support member  1  at a certain position using a mounting fixture  5 . The mounting fixture  5  may have a construction that enables it to be moved up or down on the support member  1 . The mounting fixture  5  may be attached to the upper member  4  and/or the vertical support member  1  using bolts, screws, or any other type of fastening means. In an alternative embodiment the mounting fixture  5  may comprise a first plate (not shown) connected to the upper member  4  and attached to a second plate (not shown) on the opposite side of the support member  1  via the fastening means. In a second alternative embodiment the mounting fixture  5  may comprise a first plate (not shown) connected to the upper member  2 , and one or more U-shaped fastening means may be connected to the first plate. In a preferred embodiment the mounting fixtures  3 ,  5  may be identical. This enables the upper member to be adjusted according to different size animals. 
     Alternatively, the upper member  4  may be mounted directly on the support member  1  using any type of fastening means or by welding or any similar process. 
     In a preferred embodiment the lower member  2  extends further than the upper member  4 . The lower member  2  and/or the upper member  4  may also be moved in the longitudinal direction according to the intended use of the stall dividers and the size of the animals. 
     The lower member  2  may extend away from the support member  1  at a predetermined angle a relative to the longitudinal direction of the support member. The upper member  4  may extend away from the support member  1  at a predetermined angle  13  relative to the longitudinal direction of the support member. The upper member  4  may be angled differently relative to the support member  1 , or at the same angle as the lower member  2 . This enables the lower and upper members to be placed at optimum angles relative to the size of the animals. 
     In a preferred embodiment, for increased comfort and welfare, the lower member  2  is positioned at an inclined angle, whereby the animal is guided into the resting position and is prevented from getting stuck while resting. The upper member  4  is positioned perpendicularly or essentially perpendicularly to the vertical support member  1 , which will prevent the animal from entering the adjacent stalls. 
     The lower  2  and upper member  4  may be made of a material that enables them to bend or deflect to a certain degree when the animal applies pressure to the members. Such material may be plastic, fibreglass or similar resilient materials. Any other type of material having the same properties may be used. Alternatively, the lower  2  and upper member  4  may be made of different materials or comprise different properties. This enables the stall divider to increase the comfort and welfare of the animals. 
     The lower  2  and upper member  4  may be shaped like a hollow or a solid tube or rod having a circular, elliptic, square, or any other cross-sectional shape. The thickness or diameter of the tubes or rods in the lower member  2  and in the upper member  4  may differ or may be the same. This enables the stall divider to deflect or bend more when pressure is applied, thus increasing the comfort and welfare of the animals. 
     Optionally, the lower  2  and/or upper member  4  may also comprise an outer layer of a soft or elastic material, such as rubber, polymer, or similar materials, for added comfort. 
     In alternative embodiment the lower  2  and/or upper member  4  may be connected to a spring-like element mounted on the mounting fixture. This enables the lower  2  and/or upper member  4  to bend when pressure is applied to that particular member. 
     The bendable or deflectable material enables the other end of the lower member  2  and the upper member  4  to be moved in the horizontal and/or in the vertical direction when pressure is applied to the member. The other end will return to its starting position when the pressure on the member subsides. The other end of the lower member  2  and the upper member  4  may be closed and comprise rounded edges, so that the animal does not get hurt. 
     A crossing member  6  may be mounted on top or below the upper member  4  at a distance from the vertical support member  1  and perpendicularly to the upper member  4 . The crossing member  6  may be secured to the upper member  4  using fastening elements (not shown). This enables the crossing member  6  to be positioned according to different size animals. 
     The fastening elements may be two or more U-shaped bracket elements held together using any type of fastening means. The bracket elements or fastening means may be made of plastic, metal, or similar materials, which will enable the bracket elements to break away when excessive pressure is applied to the crossing member  6 . Alternatively, both the bracket elements and the fastenings means may be made of the same material. 
     The crossing member  6  may be made of a different bendable or deflectable material than the lower and upper members  2 ,  4  but having the same properties. In a preferred embodiment all three members are made of the same material. By using a flexible material, the animal does not get hurt when hitting the members  2 ,  4 ,  6 , and the animal is able to rest comfortably against these members. This also reduces the noise level due to “banging” in the stable and results in less noisy animals, whereby comfort and welfare is increased. 
     The crossing member  6  may comprise the same hollow or solid structure and shape as the lower member  2  or the upper member  4 . An outer layer of a soft or elastic material, such as rubber, polymer, or similar cushioning materials, may be applied to the crossing member  6  for added comfort. 
       FIG. 2  shows another embodiment of the invention. As shown in  FIG. 1 , the lower member  2  and the upper member  4  are positioned on the same side of the support member  1 . An additional lower  2 ′, upper  4 ′, and crossing  6 ′ member are positioned at the opposite side of the support member  1 . The two lower members  2 ,  2 ′ may be positioned opposite each other or at different positions. The additional lower member  2 ′ may be attached to the mounting fixture  3  or to a third mounting fixture (not shown). Similarly, the two upper members  4 ,  4 ′ may be positioned opposite each other or at different positions. The additional upper member  4 ′ may be attached to the mounting fixture  5  or to a forth mounting fixture (not shown). 
     In a method of use as shown in  FIG. 3  a plurality of stall dividers may be mounted inside the stable in rows or in columns. The support members  1  may be spaced equally between the rows or columns. The heights of the lower members  2 ,  2 ′ and the upper members  4 ,  4 ′ may be adjusted by moving the mounting fixtures  3 ,  5 , respectively, up or down on the vertical support member  1 . The crossing members  6 ,  6 ′ may be positioned on top or below the upper members  4 ,  4 ′ extending throughout the entire length of the rows and/or columns. The crossing members  6 ,  6 ′ may be secured to the upper members  4 ,  4 ′ at any desired distance from the vertical support member  1 . 
     A support member  1  may be positioned at each end of a row and/or column. Alternatively, a solid structure, such as a wall, may be positioned at each end of a row and/or column. 
     The lower member  2  guides the animals into their resting position, while the upper member  4  guides the animal in and out of the stall and prevents the animal from turning around in the stall. The upper member  4  also prevents the animal from entering an adjacent stall. The crossing member  6  marks the end of the stall for the animal when the animal enters the stall. If the animal wants to move through the stall, the construction of the crossing member  6  and the fastening elements enables the animal to move through the stall without getting hurt or injured. 
     A resting rail (not shown) may be mounted on the vertical support member  1  near the ground or floor, so that the animal may rest comfortably. Alternatively, a resting structure (not shown) may be positioned on the ground or floor near or between the vertical support members  1 , so that the animal may rest comfortably. 
     The stall divider provides an easy and simple way of mounting the members  2 ,  4 ,  6  on the support member  1 , thus making the structure more versatile. The upper  4  and crossing  6  members provide more space for the animal to move its head around, thereby increasing comfort and welfare of the animals. 
     The construction described in the preferred embodiment may be combined with any one of the described alternative embodiments. The stall divider is suitable for stables comprising cows, pigs, sheep, horses, goats, or other animals.
