~nother known hinge ox use in games court~ with a ylass wall is similar to a conventional door hinge.
It is fitted.to the edge of the doo~ and has a pivotal ~ ¦
axis in the plane o the door and very close to the . . hinged edge of the door to enable the door to open inwa~ds with the hinged mechanism on the outside o the c~u~t.

mechanism together with the need for separate fixing of such mechanism to the door and the surroundlng wall.
A further disadvantage of the second known door hinge is that such a hinge has hitherto not been capable of withstanding sudden large forces applied thereto, -for instance, as might arise from the collision of a heavy player striking the door at speed. I such an event occurs then it is possible for the hinges to burst away from the wall~
In accordance with the present invention there is provided a door hinge for use in combination with a door having a cut-out portion extending in~ardly from one vertical edge thereof, the hinge comprising a first portion to be fitted to the door, a second portion to be fitted to a wall adjacent to the door, said second portion being pivotally connected to said 15 first portion, and a third portion integral with said second portion and connectable to a wall support member extending at one side of the wall in a direction out of the plane of the wall, the hinge being mountable on said one side of the wall and door so as not to extend beyond the surfaces of the door and the 20 wall on the other side of the wall, and wherein said hinge is adapted so that w~en fitted its pivotal axis lies between the lateral sides of the cut-out portion provided in the door.
The first portion of the hinge may have arms defining a bifurcated portion receiving a tongue extending from the second 25 portion thereof, the bifurcated portion and the tongue together being substantially flush with the interior face of the door, the tongue having a convex end which lies close to a 6~
corresponding straight surface of the second portion provided between the arms defining the bi~urcated portion.
Also in accordance wi-th the invention there is provided a door hinge in combination with a door comprising a first 5 portion to be fitted to the door, a second portion to be fitted to a wall adjacent to the door, said second portion being pivotally connected to said first portion, and a third portion in~egral with said second portion and connectable to a wall support member extending at one side of the wall in a direction out of the plane of the wall, the hinge being mountable on said one side of the wall and door so as not to extend beyond the surfaces of the door and the wall on the other side of the wall, and wharein said hinge is adapted so that when fitted its pivotal axis lies between the lateral sides of a cut-out por~ion provided in the door, said cut-out portion extending inwardly from one vertical edge of the door.
The first portion of the hinge may have arms defining a biurcated por-tion receiving a tongue extending from the second portion thereof, the bifurcated portion and the tongue together substantially filling the cut-out portion of the door and being substantially flush with the interior face of the door, the tongue having a convex end which lies close to a corresponding straight surface of the second portion ~rovided between the arms defining the bifurcated portion.
~75 Ei~
A hinge in accordance with the present inven-tion allows forces which are applied to the door to be transferred onto the wall support member, thereby reducing the risk of the door bursting from its hinges. Two or more such hinges may be used to fix the door to an adjacent wall and they may be provided sufficiently close together to ensure that the door will not bend between its hinges to any significant extent.
The door may be made of any suitable material, for instance, glass or other clear plastics material (e.g. a methylacrylate or acrylic). The wall may also be made of the same or other more ~olid materials, for instance, brick.
The wall support member may be made of, for instance, glass, steel, wood, aluminium or concrete.
Preferably the length o~ said third portion is at least one tenth the len~th of said second portion. In one embodiment, the length of the third portion is approximately two fifths the length of the second portion.
Preferably the second portion comprises a wall abutting part ~nd, extending therefrom, a part mating with said first portion. Preferabl~ said third portion of the hinge is at least half the length oE said wall abutting part. In one embodiment the length of the third portion is two thirds the length of the wall abutting part.
Preferably said third portion is of a width substantially the same as that of said first and second portions or either of them.
Preferably the thickness of the parts of all three portions that are in contact with the surface of the wall, the door, or the wall support member are all approximately the same and of a comparable thickness to that o~ the wall, the door and/or the wall support member. More preferably a streng-thening rib of greater thic~ness runs along said second portion to the third portion.
It will be noted that the pivotal axis lies between the lateral sides of the said cut-out portion, and it may be within the cut-out portion or outside the plane of an exterior surface of the doorO
In a preerred embodiment the pivotal axis is positioned close to, but not on, the edge of the door nearer to that adjacent wall to which the hinge is connected. When the door is opened in a direction into the games court, a heel portion of the door swings outwards. A door stop placed outside the court may limit the movement of the heel portion and the extent of opening of the door may he restricted in this way.
Alternatively, a stop integral with or attached to the hinge, but not intruding into the area of play, may be provided.
Preferably there is allowed some degree of movement of the door in the opposite direction to that in which -the door opens.
The present invention also provides a wall for a games court, the wall including a door which is fixed to the remainder of -the wall by means of hinges according to the invention.
- 5a -ii6~5 An embodiment of the present invention will now be described, by way of example only, and with reerence to the accompanying drawings, in which:-Figure 1 is a side elevation of a door hinge in5 accordance with the present invention;
Figure 2 is a top plan of the door hinge of Figure l;
Figure 3 is an end elevation of the door hinge of Figure l; and Figure 4 is a perspective view of a section through the hinge of Figure 1 when fitted to a games court glass door and adjacent glass wall.
Referring to Figure 4 of the accompanying drawings, a games court may be, for instance, a squash court having a rear wall 20 made of glass. Rear wall 20 includes a glass door 23 and one or more wall support members or rectangular portions 24 (Fig.4) in the form of glass fins extend.ing - 5b -5~
a short distance outwardly from wall 20 and arranyed in a vertical plane~ Each wall support member 12 is fixed to wall 20 by means of brackets (not shown).
The door 23 is provided with two vertically spaced apart rectangular cutout por-tions 19, each cutout portion 19 extending inwardly from one vertical edge of door 23.
Associated with each cutout portion 19 is a door hinge 1. Door hinge 1 comprises a first portion 3 fixed to the door 23 and a second portion 17 which is Eixad to the wall 20.
Integral wi-th and extending at right angles to the second portion S is a third portion 17 which is fixed to wall support member 24 by means of bolts passing through bores 15.
~ eferring to Figures 1 to 4 the first portion 3 of hinge 1 includes a portion 4 substantially rectangular in front elevation which abuts the exterior surface of door 23.
The portion 4, in top plan view, as best seen in Figures 2 and 4, is of a varying thickness. The part 4a, the most remote part from the door edge of the portion 4, is of a comparable thickness to that of the door 23 itself. However, part 4_ of the portion 4, lying nearest the door edge, is of approximately twice the thickness of part 4a. Both part 4a and part 4_ have substantially planar fron~ surfaces which extend parallel to the plane of door 23.
An intermediate inclined part 4c lies between parts 4a and 4b. The thickness of the part 4c varies substantially linearly from a thickness equal to that of part 4a, to one equal to that of part 4_, and so presents a substantially smooth transition from part 4_ to part 4b. Extending through the rectangular portion 4 are screw holes 9 so that this portion 3 of the hinge may be fixed,by means of screws, to the door 23.
Portion 3 also includes a bifurcated portion 6 which is of a thickness approximately three -times that of the part ~a of the portion 3, and of a length approximately equal to the depth of the cutout portion 19 of the door 23. Bifurca-ted portion 6 substantially fills cutout portion 19 apart from the space between the arms of this portion.
The rear face 2 of the bifurcated portion 6 is substantially planar with the inner face of the door 23, this portion 6 also having lateral side faces 6a that register with respective lateral sides of the cutout portion 19.
The front face of the portion 6 is, in the region 13a nearest the hinge part 4b, planar with the corresponding face of -the part 4b. However, in the region 13c nearest the edge of the door 23, the front face lies in the same plane as the corresponding face of the part ~a of the hinge portion 3. An intermediate inclined region 13b between these two above-mentioned regions 13a and 13c provides a substantially smooth transition area.
Extending vertically through the upper arm of bifurcated portion 6 and also about halfway through the lower arm of said portion 6 from the upper surface thereof are bores 8 and 10 which are in vertical alignment with each other. The Z5 centres of the bores are in substantially the same plane perpendlcular to the door 23 as the interface between the regions 13a and 13b of the front face 13 of the hinge portion 6.
~7~ 5 The second portion 5 of hinge 1 includes rectangular portion 12 which is slightly longer than the above-mentioned rectangular portion 4 but is similarly provided with screw holes 11 whereby portion 5 can be fixed to wall 20. The rectangular portion 12 is of substantially equal thickness to that of the wall 20. Extending laterally and centrally from rectangular portion 12 is a tongue 14 which has a thickness approximately three times that of rectangular portion 12 and equal to that of the region 13a of the bifurcated portion 6 Indeed tongue 14 is located mainly between the arms of bifurcated portion 6 and is provided with a convex end 16 which lies close to a corresponding straight surface 40 provided between the arms of bifurcated portion 6 of portion 3. Tongue 14 is also provided with a bore 18 which, as best seen in Figure 1, is in vertical alignment with bores 8 and 10 of bifurcated portion 6. A pin 7 extends from the bottom of bore 10 through bore 18 to the top of bore 8 allowing pivotal movement between the hinge parts about the longitudinal axis of pin 7.
Tongue 14 has a lateral side face 14a (Fig.3) registering with adjacent side faces 6a of portion 6, and biEurcated portion 6 and tongue 14 toyether fill substantially the whole of cutout 19. The arrangement is such that the door may be open, pivoting about pin 7 in a direction away from wall support member 24 that is to say, into the squash court. A
portion of the door, a so-called heel portion, which extends between the pivot axis of the door and the edge 22 of the door, will, when the door is opened, swing outwardly, that is to say, in a direction away from the interior of the squash court. An appropriately located door stop fixed into the floor will be engaged by this heel portion of the door and so limit the maximum swing o~ the door, thereby avoiding the door being swuny into the adjacent wall 20. In addition, the shape of the surfaces 16 and 40 of the first and second hinge portions 3 and 5 allows a small degree of movement of the door in the direction out of the squash court. This reduces the rigidity of the system so that the shock of, for instance, a player colliding with the door 23 does not break the hinge.
The third portion 17 of hinge 1 has approximately the same thickness as portions 3 and 5 where they abut door 23 and wall 20 respectively. Portion 17 has a length which is approximately two fifths the total length of the second portion, that is to say, including tongue 14. The length of portion 17 is about two thirds of the length of the wall abutting rectangular portion 12 of portion 5. Portion 17 is provided with screwholes 15 whereby it may be fi~ed to wall support member 24. In this way forces applied to door 23, for instance, as a result of a collison of a player with the interiox surfaces of the door may be dispersed at least partly into wall support member 24 as well as wall 20, thereby reducing the risk of the door bursting from its hinge and/or the hinge breaking away from the wall 20.
A strengthening rib 35 runs substantially longitudinally along the central region of the second hinge portion 5 from the tongue 14 to connect with the third hinge _ g ~L756~L~
portion 17. The rib 35 has a thickness approximately equal to that of the part 12 of the hinge portion 5, at its interface with the tongue portion 14. The thickness increases substantially linearly in a direction lon~itudinally of the hinge 1, until at its connection with the third hinge portion 17, the thickness of the rib 35 substantially equal to the length of the portion 17.
The rib 35 serves to transmit the shock o-f an impact with the door 23, and hence the hinge 1, to the third hinge portion 17, from where it can be transmitted into the wall support member 24~
The additional thickness of the bifurcated portion 6 and tongue 14 extends, as is best seen in Figures 2, in a direction towards the interior of the court. The arrangement is such that the interior side surfaces of tongue 14 and bifurcated portion 6 are flush with each other and with the interior surfaces of door 23 and wall 20. Accordingly, no part of the hinge projects either inwardly ox outwardly from the interior surfaces of the wall 23 and door 20 and a smooth continous playing surface, including door 23, wall 20 and the above-mentioned portions of the hinge 1, is provided.
In the embodiment illustrated the longitudinal axis of pivot pin 7 lies between the lateral side walls of the cutout portion 19 and in the plane of the exterior surface or boundary line of the door. It may instead lie within the cutout portion or outside the plane of the door exterior surface.
- ln-~5~
Hinge l may be made of any suitable material, for instance, a transparent nylon or a suitable metal.
Conveniently, the second hinge portion 5, the third hinge portion 17, and the strengthening rib 35 may be formed as an integral unit, for example by moulding from a suitable plastics materialO

A further disadvantage of the second known door hinge is that such a hinge has hitherto not been capable of withstanding sudden large forces applied thereto, -for instance, as might arise from the collision of a heavy player striking the door at speed. I such an event occurs then it is possible for the hinges to burst away from the wall~
In accordance with the present invention there is provided a door hinge for use in combination with a door having a cut-out portion extending in~ardly from one vertical edge thereof, the hinge comprising a first portion to be fitted to the door, a second portion to be fitted to a wall adjacent to the door, said second portion being pivotally connected to said 15 first portion, and a third portion integral with said second portion and connectable to a wall support member extending at one side of the wall in a direction out of the plane of the wall, the hinge being mountable on said one side of the wall and door so as not to extend beyond the surfaces of the door and the 20 wall on the other side of the wall, and wherein said hinge is adapted so that w~en fitted its pivotal axis lies between the lateral sides of the cut-out portion provided in the door.
The first portion of the hinge may have arms defining a bifurcated portion receiving a tongue extending from the second 25 portion thereof, the bifurcated portion and the tongue together being substantially flush with the interior face of the door, the tongue having a convex end which lies close to a 6~
corresponding straight surface of the second portion provided between the arms defining the bi~urcated portion.
Also in accordance wi-th the invention there is provided a door hinge in combination with a door comprising a first 5 portion to be fitted to the door, a second portion to be fitted to a wall adjacent to the door, said second portion being pivotally connected to said first portion, and a third portion in~egral with said second portion and connectable to a wall support member extending at one side of the wall in a direction out of the plane of the wall, the hinge being mountable on said one side of the wall and door so as not to extend beyond the surfaces of the door and the wall on the other side of the wall, and wharein said hinge is adapted so that when fitted its pivotal axis lies between the lateral sides of a cut-out por~ion provided in the door, said cut-out portion extending inwardly from one vertical edge of the door.
The first portion of the hinge may have arms defining a biurcated por-tion receiving a tongue extending from the second portion thereof, the bifurcated portion and the tongue together substantially filling the cut-out portion of the door and being substantially flush with the interior face of the door, the tongue having a convex end which lies close to a corresponding straight surface of the second portion ~rovided between the arms defining the bifurcated portion.

A hinge in accordance with the present inven-tion allows forces which are applied to the door to be transferred onto the wall support member, thereby reducing the risk of the door bursting from its hinges. Two or more such hinges may be used to fix the door to an adjacent wall and they may be provided sufficiently close together to ensure that the door will not bend between its hinges to any significant extent.
The door may be made of any suitable material, for instance, glass or other clear plastics material (e.g. a methylacrylate or acrylic). The wall may also be made of the same or other more ~olid materials, for instance, brick.
The wall support member may be made of, for instance, glass, steel, wood, aluminium or concrete.
Preferably the length o~ said third portion is at least one tenth the len~th of said second portion. In one embodiment, the length of the third portion is approximately two fifths the length of the second portion.
Preferably the second portion comprises a wall abutting part ~nd, extending therefrom, a part mating with said first portion. Preferabl~ said third portion of the hinge is at least half the length oE said wall abutting part. In one embodiment the length of the third portion is two thirds the length of the wall abutting part.
Preferably said third portion is of a width substantially the same as that of said first and second portions or either of them.
Preferably the thickness of the parts of all three portions that are in contact with the surface of the wall, the door, or the wall support member are all approximately the same and of a comparable thickness to that o~ the wall, the door and/or the wall support member. More preferably a streng-thening rib of greater thic~ness runs along said second portion to the third portion.
It will be noted that the pivotal axis lies between the lateral sides of the said cut-out portion, and it may be within the cut-out portion or outside the plane of an exterior surface of the doorO
In a preerred embodiment the pivotal axis is positioned close to, but not on, the edge of the door nearer to that adjacent wall to which the hinge is connected. When the door is opened in a direction into the games court, a heel portion of the door swings outwards. A door stop placed outside the court may limit the movement of the heel portion and the extent of opening of the door may he restricted in this way.
Alternatively, a stop integral with or attached to the hinge, but not intruding into the area of play, may be provided.
Preferably there is allowed some degree of movement of the door in the opposite direction to that in which -the door opens.
The present invention also provides a wall for a games court, the wall including a door which is fixed to the remainder of -the wall by means of hinges according to the invention.
- 5a -ii6~5 An embodiment of the present invention will now be described, by way of example only, and with reerence to the accompanying drawings, in which:-Figure 1 is a side elevation of a door hinge in5 accordance with the present invention;
Figure 2 is a top plan of the door hinge of Figure l;
Figure 3 is an end elevation of the door hinge of Figure l; and Figure 4 is a perspective view of a section through the hinge of Figure 1 when fitted to a games court glass door and adjacent glass wall.
Referring to Figure 4 of the accompanying drawings, a games court may be, for instance, a squash court having a rear wall 20 made of glass. Rear wall 20 includes a glass door 23 and one or more wall support members or rectangular portions 24 (Fig.4) in the form of glass fins extend.ing - 5b -5~
a short distance outwardly from wall 20 and arranyed in a vertical plane~ Each wall support member 12 is fixed to wall 20 by means of brackets (not shown).
The door 23 is provided with two vertically spaced apart rectangular cutout por-tions 19, each cutout portion 19 extending inwardly from one vertical edge of door 23.
Associated with each cutout portion 19 is a door hinge 1. Door hinge 1 comprises a first portion 3 fixed to the door 23 and a second portion 17 which is Eixad to the wall 20.
Integral wi-th and extending at right angles to the second portion S is a third portion 17 which is fixed to wall support member 24 by means of bolts passing through bores 15.
~ eferring to Figures 1 to 4 the first portion 3 of hinge 1 includes a portion 4 substantially rectangular in front elevation which abuts the exterior surface of door 23.
The portion 4, in top plan view, as best seen in Figures 2 and 4, is of a varying thickness. The part 4a, the most remote part from the door edge of the portion 4, is of a comparable thickness to that of the door 23 itself. However, part 4_ of the portion 4, lying nearest the door edge, is of approximately twice the thickness of part 4a. Both part 4a and part 4_ have substantially planar fron~ surfaces which extend parallel to the plane of door 23.
An intermediate inclined part 4c lies between parts 4a and 4b. The thickness of the part 4c varies substantially linearly from a thickness equal to that of part 4a, to one equal to that of part 4_, and so presents a substantially smooth transition from part 4_ to part 4b. Extending through the rectangular portion 4 are screw holes 9 so that this portion 3 of the hinge may be fixed,by means of screws, to the door 23.
Portion 3 also includes a bifurcated portion 6 which is of a thickness approximately three -times that of the part ~a of the portion 3, and of a length approximately equal to the depth of the cutout portion 19 of the door 23. Bifurca-ted portion 6 substantially fills cutout portion 19 apart from the space between the arms of this portion.
The rear face 2 of the bifurcated portion 6 is substantially planar with the inner face of the door 23, this portion 6 also having lateral side faces 6a that register with respective lateral sides of the cutout portion 19.
The front face of the portion 6 is, in the region 13a nearest the hinge part 4b, planar with the corresponding face of -the part 4b. However, in the region 13c nearest the edge of the door 23, the front face lies in the same plane as the corresponding face of the part ~a of the hinge portion 3. An intermediate inclined region 13b between these two above-mentioned regions 13a and 13c provides a substantially smooth transition area.
Extending vertically through the upper arm of bifurcated portion 6 and also about halfway through the lower arm of said portion 6 from the upper surface thereof are bores 8 and 10 which are in vertical alignment with each other. The Z5 centres of the bores are in substantially the same plane perpendlcular to the door 23 as the interface between the regions 13a and 13b of the front face 13 of the hinge portion 6.
~7~ 5 The second portion 5 of hinge 1 includes rectangular portion 12 which is slightly longer than the above-mentioned rectangular portion 4 but is similarly provided with screw holes 11 whereby portion 5 can be fixed to wall 20. The rectangular portion 12 is of substantially equal thickness to that of the wall 20. Extending laterally and centrally from rectangular portion 12 is a tongue 14 which has a thickness approximately three times that of rectangular portion 12 and equal to that of the region 13a of the bifurcated portion 6 Indeed tongue 14 is located mainly between the arms of bifurcated portion 6 and is provided with a convex end 16 which lies close to a corresponding straight surface 40 provided between the arms of bifurcated portion 6 of portion 3. Tongue 14 is also provided with a bore 18 which, as best seen in Figure 1, is in vertical alignment with bores 8 and 10 of bifurcated portion 6. A pin 7 extends from the bottom of bore 10 through bore 18 to the top of bore 8 allowing pivotal movement between the hinge parts about the longitudinal axis of pin 7.
Tongue 14 has a lateral side face 14a (Fig.3) registering with adjacent side faces 6a of portion 6, and biEurcated portion 6 and tongue 14 toyether fill substantially the whole of cutout 19. The arrangement is such that the door may be open, pivoting about pin 7 in a direction away from wall support member 24 that is to say, into the squash court. A
portion of the door, a so-called heel portion, which extends between the pivot axis of the door and the edge 22 of the door, will, when the door is opened, swing outwardly, that is to say, in a direction away from the interior of the squash court. An appropriately located door stop fixed into the floor will be engaged by this heel portion of the door and so limit the maximum swing o~ the door, thereby avoiding the door being swuny into the adjacent wall 20. In addition, the shape of the surfaces 16 and 40 of the first and second hinge portions 3 and 5 allows a small degree of movement of the door in the direction out of the squash court. This reduces the rigidity of the system so that the shock of, for instance, a player colliding with the door 23 does not break the hinge.
The third portion 17 of hinge 1 has approximately the same thickness as portions 3 and 5 where they abut door 23 and wall 20 respectively. Portion 17 has a length which is approximately two fifths the total length of the second portion, that is to say, including tongue 14. The length of portion 17 is about two thirds of the length of the wall abutting rectangular portion 12 of portion 5. Portion 17 is provided with screwholes 15 whereby it may be fi~ed to wall support member 24. In this way forces applied to door 23, for instance, as a result of a collison of a player with the interiox surfaces of the door may be dispersed at least partly into wall support member 24 as well as wall 20, thereby reducing the risk of the door bursting from its hinge and/or the hinge breaking away from the wall 20.
A strengthening rib 35 runs substantially longitudinally along the central region of the second hinge portion 5 from the tongue 14 to connect with the third hinge _ g ~L756~L~
portion 17. The rib 35 has a thickness approximately equal to that of the part 12 of the hinge portion 5, at its interface with the tongue portion 14. The thickness increases substantially linearly in a direction lon~itudinally of the hinge 1, until at its connection with the third hinge portion 17, the thickness of the rib 35 substantially equal to the length of the portion 17.
The rib 35 serves to transmit the shock o-f an impact with the door 23, and hence the hinge 1, to the third hinge portion 17, from where it can be transmitted into the wall support member 24~
The additional thickness of the bifurcated portion 6 and tongue 14 extends, as is best seen in Figures 2, in a direction towards the interior of the court. The arrangement is such that the interior side surfaces of tongue 14 and bifurcated portion 6 are flush with each other and with the interior surfaces of door 23 and wall 20. Accordingly, no part of the hinge projects either inwardly ox outwardly from the interior surfaces of the wall 23 and door 20 and a smooth continous playing surface, including door 23, wall 20 and the above-mentioned portions of the hinge 1, is provided.
In the embodiment illustrated the longitudinal axis of pivot pin 7 lies between the lateral side walls of the cutout portion 19 and in the plane of the exterior surface or boundary line of the door. It may instead lie within the cutout portion or outside the plane of the door exterior surface.
- ln-~5~
Hinge l may be made of any suitable material, for instance, a transparent nylon or a suitable metal.
Conveniently, the second hinge portion 5, the third hinge portion 17, and the strengthening rib 35 may be formed as an integral unit, for example by moulding from a suitable plastics materialO
