Description

Hinge for a Door for a Paddock, a Door Comprising the Hinge, and a Board Comprising the Door Field of inventionThe present invention relates to a hinge assembly for a door for a paddock having a tilting board, Background of invention The board of a paddock has to be quite tall to prevent a horse to fall over the board. Aboard up to two meter tall is not uncommon. Doors for entering the paddock have tohave the same height to prevent corners, where the board and door meet. The board toa paddock is tilted so that even though the horse walks close to the board the rider'sknees are not injured. The tilted board means that the door also has to be tilted in orderfor the door to flush with the board. To open the tilted door, the centre of gravity of thedoor has to be raised, with the result that a lot of force is needed when opening thedoor. An adult may have difficulty in opening such a door especially if the door is alarger door for giving access to a vehicle, for a child opening such a door may be insurmountable.

Summary of invention The present disclosure relates to a hinge assembly for a door for a paddock having atilting board, the hinge assembly comprising a first hinge configured for rotating arounda first rotational axis, wherein a first end of the first hinge is configured for beingconnected to a door panel, and a second hinge configured for rotating around a secondrotational axis, wherein a first end of the second hinge is configured for beingconnected to a tilting board, wherein a second end of the first hinge and a second endof the second hinge are connected, and wherein the first rotational axis and the second rotational axis are substantially perpendicular to each other.

The door and the board are not necessarily part of the claimed subject-matter.However, to make it easier to illustrate and to present to the reader the benefits of thehinge assembly, the door and the board are still used in the arguments below to describe the function of the hinge assembly.

Since a door attached to a board by the hinge assembly of the present invention canbe rotated around the second rotational axis from a ti|ted position to a vertical positionbefore the door is rotated around the first rotational axis from the closed to the openposition, the centre of gravity of the door does not need to be raised when opening thedoor. This especially beneficial for doors to paddocks, since such doors are normally heavy.

Even a child will be able to tilt a closed door to a vertical position and then open the door to enter the paddock. ln one embodiment the second end of the first hinge and the second end of the secondhinge can be connected to each other via a connecting member having a top end and abottom end, wherein the connecting member can have a guide positioned at the topend or the bottom end, wherein the guide can be configured for guiding the connecting member when the second hinge rotates around the second rotational axis.

That the guide positioned at the top end or the bottom end of the connecting memberhas the advantage that the torque from the weight of the door acting on the secondhinge will be distributed resulting on lower forces acting on the second hinge and the guide. lf the second hinge is positioned on the lower half of the connecting member, the guideshould preferably be positioned closer to the top end of the connecting member to thetorque from the weight of the door acting on the second hinge. Likewise, if the secondhinge is positioned on the upper half of the connecting member, the guide should preferably be positioned closer to the bottom end of the connecting member. ln one embodiment the guide can comprise at least one wheel and a track, wherein the track guides the wheel(s).

A wheel will give a very low friction force when tilting a door attached to the tilting board by the hinge assembly around the second rotational axis. ln one embodiment the at least one wheel can have a wheel rotational axissubstantially parallel with the first rotational axis, preferably at least during one position of the door, when the door is rotated around the second rotational axis.

When the wheel rotational axis is substantially parallel with the first rotational axis, anyfriction force on the wheel will be tangential to the wheel so that the friction force will be very low. lf the at least one wheel is connected to the door or to the connecting member and thetrack is connected to the tilting board, then the wheel rotational axis will be more or less parallel with the first rotational axis. lf the track is connected to the door or to the connecting member and the at least onewheel is connected to the tilting board, then the first rotational axis will change inrelation to the earth, while the wheel rotational axis will not change, when the door ismoved from the tilted position to the vertical position or vice versa. ln this situation, thefirst rotational axis and the wheel rotational axis will at least nearly parallel, and will notdeviate more than the angle of the tilting board. lf the tilting board is 15° or 20° from thevertical direction, the first rotational axis and the wheel rotational axis will form an angleof not more than 5° or 10° or 15° or 20°, respectively. Preferably, the first rotational axisand the wheel rotational axis are parallel when the door is in the tilted position flushingwith the board.

The at least one wheel can have a wheel rotational axis substantially parallel with the first rotational axis. ln one embodiment the track can have two parallel sides configured for receiving the wheel in-between the sides.

Only one wheel will be needed and the wheel will alternately be pressed against theone side and the other side. ln each case, the wheel will rotate against one of the sidesresulting in low frictional force when untilting (bringing the door to a vertical position) and tilting the door and the connecting member. ln one embodiment the second rotational axis can be configured to be substantially through or a little below the centre of gravity of the door.

The door can easily be tilted around second rotational axis without very much force, since the centre of gravity of the door is not changed. ln one embodiment the second rotational axis can be close to the bottom end of theconnecting member or wherein the second rotational axis is configured to be close tothe bottom of the board, preferably so that the door is pivotable substantially 180° around the first rotational axis. lf the second hinge is positioned close to the bottom of the board and/or the connectingmember the door can be totally opened, i.e. opened almost 180° around the firstrotational axis. When the door is totally opened, almost 180° around the first rotationalaxis, the door can rotate around the second rotational axis back to the tilted position sothat the surface of the door facing the paddock area, when the door is in the closedposition, abuts the surface of the board facing the paddock area. ln this totally openedstate, the surface friction between the surface of the board and the surface of the door will lower the torque from the door acting on the first hinge.

When the door is moved around the second rotational axis to the vertical position, thelower part of the door below the second rotational axis will be moved away from thepaddock area. When the door is then opened around the first rotational axis, the lowerpart of the door may bump into the lower part of the board before the door is totallyopened. When the lower part of the door bumps into the lower part of the board, therewill be a strong torque acting on the first hinge and may be on the second hinge thatcould potentially destroy or wear out the first hinge and/or the second hinge at least after some time of use.

Of course, if the board next to the connecting member and/or the door does not stretchall the way down to the floor of the paddock, the second hinge can be positionedfurther up and the door can still be totally opened. Of course, if the door does notstretch all the way down to the floor of the paddock, the second hinge can be positioned further up and the door can still be totally opened. ln both these examples, the second hinge can/should be considered to be close to the bottom end of the connecting member or to be configured to be close to the bottom of the board.

The skilled person will understand, how far down on the connection member and/or on the board the second hinge has to be positioned so that the door can be totally opened. ln one embodiment, if the second rotational axis is close to the bottom end of theconnecting member or if the second rotational axis is configured to be close to thebottom of the board can mean that the second rotational axis is less than one third,preferably less than one fourth, more preferably less than one fifth, even morepreferably less than one sixth, most preferably less than one tenth, of a height of theconnecting member above the bottom end of the connecting member or of a height of board above the bottom of the board.

What close to the bottom end of the connecting member or close to the bottom of theboard means will e.g. depend on the design of the first hinge or on the length of thedoor. The further away from the board and into the paddock area the first rotationalaxis is and/or the further away from the floor of the paddock the lower end of the doorand/or of the board and/or of the connecting member end, the further up the second rotational axis can be positioned and the door can still be totally opened. ln one embodiment, the first hinge can comprise at least two first hinge parts with acommon first rotational axis, or the first hinge can be a long first hinge having a length of at least one half of the height of the door.

The two first hinge parts or the long first hinge will reduce the force from the torque dueto the weight of the door acting on each of the first hinge parts or on the long firsthinge. Preferably, one of the two first hinge parts is positioned close to or at the top ofthe door and the other of the two first hinges is positioned close to or at the bottom ofthe door so that the torque will act over a long distance and result in low forces actingon the first hinges. The long hinge can preferably be at least two thirds of the height ofthe door, more preferably at least three fourths of the height of the door, even morepreferably at least four fifths of the height of the door, and most preferably at least five sixths of the height of the door. The longer the long first hinge is, the more the long hinge will reduce the force from the torque due to the weight of the door acting on the long first hinge.

Each of the at least two first hinge parts is hinge in itself. ln one embodiment, the hinge assembly can comprise a stopper, preferably of rubber,wherein the stopper can be configured for being positioned on the board above thesecond hinge for limiting rotation of the connecting member around the second rotational axis.

With the stopper attached to e.g. an end face of the board facing and carrying theconnecting member and the door, e.g. close to the top of the board or of the connectingmember, the connecting member and the door in the closed position will be given asolid support so that the connecting member and the door do not rotate around thesecond rotational axis and exposes an upper corner of the board if someone hits theupper part of the connecting member or door. lf a person or an animal would hit theupper part of the connecting member or door without the stopper attached to the board,the connecting member and door could rotate around the second rotational axis and the person or animal could be injured by the upper corner of the exposed board. lf the stopper is correctly positioned on the board the door in the closed position willflush with the board so that accidents or injuries due to a rider's knee or clothes being caught or hit by an edge of the board or of the connecting member are avoided. ln one embodiment, the hinge assembly can comprise a first shock absorber mountedon the connecting member or can be configured for being mounted on a board, and/orcan be configured for being mounted on a door, wherein the first shock absorber can be configured for absorbing the momentum of the closing door.

Since a door in a board of a paddock is so heavy, the momentum when closing thedoor could in the long run potentially destroy the hinge assembly and especially thefirst hinge if there was no first shock absorber to absorb the momentum of the closing doon The first shock absorber can comprise two first shock absorber parts, where one of thefirst shock absorber parts is connected to the door and the other of the first shockabsorber parts is connected to the connecting part or to the board, and where relative movement between the two first shock absorber parts is counteracted and absorbed.

The first shock absorber can alternatively comprise a single first shock absorber part,wherein the single first shock absorber part is connected to the door, the connectingpart or the board. lf e.g. the single first shock absorber part is connected to the door,the single first shock absorber part will be in contact with a surface of the connectingpart or the board only during the last than 5° or 10° or 15° or 20° before the doorreaches the closing position of the door. When the door is open more than the 5° or10° or 15° or 20° the single first shock absorber part will only be connected to the doorand not in contact with anything else. lf the single first shock absorber part isconnected to the connecting part or the board, the situation will be the similar, and thesingle first shock absorber part will contact the door during the last than 5° or 10° or ° or 20° before the door reaches the closing position of the door. ln one embodiment, the hinge assembly can comprise a second shock absorberconfigured for being connected to the door or the connecting member, and to the board.

The second shock absorber is preferably connected to the door or the connectingmember at one end and to the board at the other end. The second shock absorber willlower the speed the door and/or the connecting member rotates around the secondrotational axis. The lower rotational speed will reduce the stresses acting on the second hinge and on the first hinge, and will reduce the risk for personal injury. ln one embodiment the hinge assembly can comprise a spring, preferably a gas spring,configured for being connected to the board, and to the door or the connecting member above the second hinge or below the second hinge.

The spring is preferably connected to the door or the connecting member above the second hinge or below the second hinge at one end and to the board at the other end. lf the second rotational axis is positioned above the centre gravity of the door and/orthe connecting member or at the upper half of the door and/or the connecting member,the gravity will rotate the door and/or the connecting member to the vertical positionand a force will be necessary to rotate the door and/or the connecting member to theti|ted position flush with the board. The spring can then advantageously be acting torotate the door and/or the connecting member to the ti|ted position. The spring can beconnected to the door or the connecting member above the second hinge, where theforce of the spring pulls the door or the connecting member towards the ti|ted position,or the spring can be connected to the door or the connecting member below thesecond hinge, where the force of the spring pushes the door or the connecting member towards the ti|ted position.

The further away from the centre gravity of the door and/or the connecting member orfrom the centre of the door and/or the connecting member is/are, the stronger the forceof the springs has to be. This is a matter of design that the skilled person easily cancalculate. Preferably, the force of the spring can be a little over-dimensioned so that thedoor and/or the connecting member is forced to the ti|ted positioned flush with theboard, so that the door and/or the connecting member does/do not accidentally rotatesto the vertical position that could expose a dangerous corner for a passing by horse and rider. lf the second rotational axis is positioned below the centre gravity of the door and/orthe connecting member or at the lower half of the door and/or the connecting member,the gravity will rotate the door and/or the connecting member to the ti|ted position and aforce will be necessary to rotate the door and/or the connecting member to the verticalposition. The spring can then advantageously be acting to rotate the door and/or theconnecting member to the vertical position. The spring can be connected to the door orthe connecting member above the second hinge, where the force of the spring pushesthe door or the connecting member towards the vertical position, or the spring can beconnected to the door or the connecting member below the second hinge, where theforce of the spring pulls the door or the connecting member towards the vertical position.

The further away from the centre gravity of the door and/or the connecting member or from the centre of the door and/or the connecting member is/are, the stronger the force of the springs has to be. This is a matter of design that the skilled person easily cancalculate. Preferably, the force of the spring can be a little under-dimensioned so thatthe door and/or the connecting member is forced by the gravity despite the spring forceto the tilted positioned flush with the board, so that the door and/or the connectingmember does/do not accidentally rotates to the vertical position that could expose a dangerous corner for a passing by horse and rider.

These and other aspects of the invention are set forth in the following detailed description of the invention.Description of DrawingsThe invention will in the following be described in greater detail with reference to the accompanying drawings.

Figure 1 shows a perspective view of a door in a closed position hinged to a board by a hinge assembly, Figure 2 shows a perspective view of a door in an open position hinged to a board by a hinge assembly, Figure 3 shows a close up view of the guide shown in Figure 1, Figure 4 shows a close up view of the guide shown in Figure 2, and P5676sEoo Figure 5 shows a perspective view of the door hinged to the board by a second embodiment of the hinge assembly.

Detailed description of the invention The invention is described below with the help of the accompanying figures. lt would beappreciated by the people skilled in the art that the same feature or component of the device is referred with the same reference numeral in different figures.

Fig. 1 shows a door 2 hinged to a board 4 for a paddock 5 by a hinge assembly 6. Thehinge assembly 6 comprises a connecting member 8. The board deviates a little bitfrom the vertical direction. The door 2 in Fig. 1 is in a closed position, where the doorand the connecting member 8 have an inclined position with the same inclination as the board and flushes with the board. The board on the other side of the door is not shown.

Fig. 2 shows the door 2 hinged to the board 4 by the hinge assembly 6, where the door is in an open position.

The hinge assembly comprises a first hinge 10 with a substantially vertical firstrotational axis 12 and a second hinge 14 with a horizontal second rotational axis 16.The door 2 and the connecting member 8 have been rotated around the secondrotational axis 16 from the inclined position shown Fig. 1 to a vertical position in Fig. 2.The first rotational axis 12 will be vertical when door and the connecting member 8 arein the vertical position and be rotated around the second rotational axis 16 togetherwith the door and the connecting member. ln this latter position, the first rotational axis 12 will be close to the vertical position.

The first hinge 10 comprises two first hinge parts 10a,10b connected at a first end to the door 2. Each first hinge part 10a,10b is a hinge in itself.

To support the second hinge 14, a wheel 18 is attached to the bottom end ofconnecting member 8, where the wheel 18 is movable in a guide 20 comprising twoguide sides 22a,22b. The guide is connected to the board. ln the tilted or inclined position of the door shown in Fig. 1, the wheel is positioned at a first end position in the guide closest to the paddock 5, while in the vertical position of the door, the wheel has moved away from the paddock to a second end position in the guide.

A first shock absorber 24 is positioned on the door 2 on the surface of the door facingaway from the paddock 5. A protrusion 26 is attached to a sidewall 28 of the board 4 orto the connecting member 8 with support from the sidewall 28 of the board 4 so that thefirst shock absorber 24 will contact the protrusion when the door approaches the closedposition shown in Fig. 1. |fthe protrusion 26 is attached to the sidewall 28, theprotrusion 26 should be positioned close to the second rotational axis so that therelative motion of the first shock absorber 24 and the protrusion 26 is small enough tocontact each other irrespective of whether the door is in the inclined or in the vertical position.

How far ahead of the closed position of the door, the first shock absorber 24 willcontact the protrusion 26 depends on the stroke of the first shock absorber 24, wherethe stroke is the distance the shock absorber can move from a retracted position to anextended position. That the first shock absorber 24 is not connected to the protrusion 26 has the benefit that there is no restriction how much the door can be opened.

The first shock absorber 24 is especially advantageous for a double door, since each ofthe two doors in the double door can have the first shock absorber 24, and the two firstshock absorbers 24 can be adjusted, by adjusting a force that acts on the doors so that the doors flushes with each other and are straight continuation of the board.

A second shock absorber 30 is at a first end 32a connected to the sidewall 28 of theboard 4 and at a second end 32b connected to the connecting member 8 somewhatbelow the second hinge 14, for reducing the speed by which the connecting member 8and the door 2 can be rotated around the second rotational axis 16. The second shockabsorber 30 can also act as a gas spring. lf it is heavy to rotate the door from the tiltedposition to the vertical position or vice versa the second shock absorber 30 with the gas spring function will yield an extra helping force.

A stopper 34 preferably by rubber is positioned at the top of the sidewall 28 of theboard 4 for supporting the top of the connecting member 8 in the inclined position to prevent that the top end of the connecting member 8 and the door bend in a direction away from the paddock 5 if a force acts on the top end of the connecting member 8and/or the door 2. The wheel 18 and the guide 20 will also prevent the connectingmember 8 and the door from rotating further away from the vertical position than theinclined position shown in Fig. 1, if a force acts on the top end of the connectingmember 8 and/or the door 2. However, without the stopper 34 there will be a largeforce acting on the second hinge 14 as well as on the wheel 18 and the guide 20. lf theconnecting member 8 and the door 2 is a little flexible, the wheel 18 and the guide 20cannot prevent the top end of the connecting member 8 and the door to bend in adirection away from the paddock 5 when a force acts on the top end of the connecting member 8 and/or the door 2 For an opening having one door, stoppers can be positioned on a sidewall of a board,where the sidewall does not carry the hinge assembly. The stoppers can be positioned so that the door in the closed position flushes with the board.

Fig. 3 shows an enlarged view of the wheel 18 attached to a wheel holder 35 and theguide 20 of the marked area in Fig. 1. The guide comprises two parallel first slots 36 ineach guide side 22a,22b. First screws 38 attach the guide side 22a,22b to a block 39attached to the board. The block can have a damper 40 for absorbing momentum whenthe wheel and/or the wheel holder 35 hit the damper 40. The block and the damper 40are preferably positioned so that the door is in the vertical position when the wheel 18 and/or the wheel holder 35 is/are contacting the damper 40.

The first slots 36 are for adapting the inclination of the door 2 and the connectingmember 8 to have the same inclination as the board. When the inclination of the boardis big, so that the inclination of the board is far from the vertical position, the guideshould be extended to the left and the first screws 38 fastened to the guide sides22a,22b and the block 39 with the first screws 38 close to the right end of the first slots36, where left and right are in relation to the directions shown in Fig. 3. When theinclination of the board is big, the first screws 38 should be fastened closer to the other end of the first slots. ln principle, the block 39, onto which the guide 20 is fastened, can be attached to theconnecting member 8 and the wheel holder 35 with the wheel 18 can be attached tothe board.

P5676sEoo13 A lock 42 can be inserted in the guide, where the lock extends between the guide sides22a,22b to lock the wheel 18 in a position, where the door and/or the connectingmember 8 is in the tilted position. With the lock locking the wheel 18 in this way, thedoor cannot accidentally be rotated to the vertical position by e.g. a force acting on the upper half of the door from outside the paddock 5. The lock can be totally removed.

Fig. 4 shows an enlarged view of the wheel 18 attached to a wheel holder 35 and theguide 20 of the marked area in Fig. 2. Fig. shows that the wheel 18 is kept on the otherside of the lock 42 compared to in Fig. 3. The lock 42 will lock the wheel 18 in aposition, where the door and/or the connecting member 8 is in the vertical position, sothat the door will not move between the vertical and tilted positons when opening thedoor. The guide sides 22a,22b could have adjacent holes 43 along the length of theguide sides for receiving the lock 42 so that the wheel 18 can be locked in the vertical position irrespective of where in the first slots 36 the first screws 38 are tightened.

Fig. 4 also shows that the first hinge part 10b comprises two parallel second slots 44and is attached to the connecting member 8 by second screws 46 through the secondslots 44. The upper first hinge part (not shown) also comprises two parallel secondslots and is attached to the connecting member 8 in the same way. The parallel secondslots 44 enables the surface of the door 2 facing the paddock to be adjusted to flush with the surface facing the paddock of the board.

As shown in Fig. 2, the connecting member 8 has a plate 48 facing the paddock. Toadjust the surface of the connecting member 8 facing the paddock to flush with the surface of the board, the correct thickness of the plate 48 can be chosen.

Fig. 5 shows a second embodiment of the invention. ln this embodiment, a differentconnecting member 8' can be connected to the board 4 by the second hinge 14', withthe second rotational axis 16', where the second hinge is positioned close to the floor,so that the door can easily rotate 180° around the first hinge (not shown) when the door is in the vertical position.

To support the second hinge 14', the board 4 and the connecting member 8' are also connected to each other by a hinge system 50 comprising two first bars 52 and a P5676SE0014 second bar 54, where the two first bars are hinged to the connecting member 8' at oneend and to the second bar 54 at the other end, and where the second bar 54 is hingedto the board at the end of the second bar that is not hinged to the first bars. The hingesystem allows the connecting member 8', and thus also the door 2, a limited rotationaround the second rotational axis 16'. The hinge system 50 supports the second hinge14' so that the connecting member 8'and the door 2 do not fall into the paddock 5around the second rotational axis 16', and so that door 2 in the closed position doesnot rotate so that the lower corner of the door away from the connecting member 8' rests on the ground.

The hinge system 50 in this embodiment could easily be replaced by the wheel andguide described above, where the wheel is attached to the connecting member 8', and the guide is attached to the board 4.

A second shock absorber 30' is at a first end 32a' connected to the board 4 and at asecond end 32b' connected to the connecting member 8', for reducing the speed bywhich the connecting member 8' and the door 2 can be rotated around the second rotational axis 16'.

A spring 52 like e.g. a gas spring, is at a first end 54a connected to the board 4 and ata second end 54b connected to the connecting member 8', for balancing the torque around the second rotational axis 16' from the weight of the door 2 and the connectingmember 8'. Without the spring 52, it can be quite heavy to rotate the door 2 around the second rotational axis 16' from the tilted position to the vertical position.

The second shock absorber 30' can act as a gas spring and in that case the spring 52 is superfluous.

All feature of the first embodiment can be combined with the second embodiment for achieving the same benefits.
