Abstract

A hinge (10) has a first leaf (12), second leaf (14) and third leaf (20). The first leaf (12) and second lead (14) are pivotally connected at an axis (18). The second leaf (14) and third leaf (20) are pivotally connected at an axis (24). In one example, the leaf (12) is attached to a door frame and the leaf (20) is attached to a door, so that the door may open and close in the frame by a motion which involves pivoting about both axes (18, 24).

Description

Hinge

The present invention relates to hinges and in particular, but not exclusively, to hinges for doors such as patio doors, French windows, conservatory doors and the like.

A conventional arrangement for installing conservatory doors, patio doors, French windows and the like, is to provide a frame within an aperture in the brickwork of the building, set back from the external face of the brickwork. The door is attached to the frame by means of a hinge. The presence of brickwork beyond the frame, although advantageous for aesthetic considerations, is found to limit the motion of the door by abutment between the door and the proud brickwork.

The present invention provides a hinge for providing a hinge connection between first and second members, the hinge comprising a first leaf for attachment to the first member, a second leaf, a first pivot connection between the first and second leaves and defining a first hinge axis, a third leaf for attachment to the second member, and a second pivot connection between the second and third leaves and defining a second hinge axis, whereby the first and second members may move relative to each other by a motion which involves pivoting about both axes. Preferably, at least one of the pivot connections has associated lock means re easably operable to prevent movement about the corresponding hinge axis during a part of the said motion. The lock means may prevent movement about the corresponding hinge axis except when the other pivot connection is in a predetermined condition. The lock means is preferably released by the arrival of the other pivot connection at the predetermined condition. The lock means may include lock surfaces which are engageable to lock the associated pivot connection. The lock surfaces may move out of engagement as the other pivot connection reaches a predetermined condition. The lock surfaces may be fixed relative to respective leaves. The second pivot connection is preferably lockable by means of at least one lock surface carried by the third leaf and which is engageable with at least one lock surface carried by the first leaf. At least one of the lock surfaces may be provided by a plunger member carried by one of the leaves and resiliently biased to a locking position at which the plunger member engages a lock surface on another of the leaves, to lock the associated pivot connection, there being plunger movement means operable to move the plunger member out of engagement, as the other pivot connection reaches the predetermined condition. The plunger movement means may comprise cam means.

Preferably both pivot connections have associated lock means as aforesaid. Preferably one of the pivot connections has each of the lock means of the types defined above.

At least one of the pivot connections preferably allows axial adjustment of one of the connected leaves relative to the other. The adjustable pivot connection may comprise a pin member carried by one of the leaves to define the pivot axis, the pin member carrying a thread to engage with the other leaf, and being rotatable about the pivot axis, whereby to move the other leaf axially relative to the said one leaf. The thread may be formed on a sleeve carried by the pin member. The thread may include a formation which tends to bind the thread with the said other leaf, to rotate therewith, during normal use, whereby axial adjustment is prevented except by overcoming the said binding. The said one leaf may have two knuckles between which a knuckle of the other leaf is received, the pin member extending through all three knuckles to form the pivot connection. The pivot member may be accessible for adjustment through at least one of the said two knuckles. An access aperture is preferably provided through the one of the said two knuckles. The access aperture may be provided with a cap to prevent unauthorised access. The cap may be retained in position by a securing member which is inaccessible during at least part of the pivot motion.

The pin member may have a portion of its length which is non-circular in section, to facilitate rotation. The non-circular portion may carry at least one bush which is circular in external section to provide a bearing in a circular cavity in the said one leaf.

The present invention also provides a hinge comprising a first leaf, a second leaf and a pivot connection between the leaves, the pivot connection comprising a pin member carried by one of the leaves to define the pivot axis, the pin member carrying a thread to engage with the other leaf, and being rotatable about the pivot axis, whereby to adjust the position of the other leaf axially relative to the said one leaf.

The thread may be formed on a sleeve carried by the pin member. The thread may include a formation which tends to bind the thread with the said other leaf, to rotate therewith, during normal use, whereby axial adjustment is prevented except by overcoming the said binding. The said one leaf may have two knuckles between which a knuckle of the other leaf is received, the pin member extending through all three knuckles to form the pivot connection. The pivot member may be accessible for adjustment through at least one of the said two knuckles. An access aperture is preferably provided through the one of the said two knuckles. The access aperture may be provided with a cap to prevent unauthorised access. The cap may be retained in position by a securing member which is inaccessible during at least part of the pivot motion. The pin member may have a portion of its length which is non-circular in section, to facilitate rotation. The non-circular portion may carry at least one bush which is circular in external section to provide a bearing in a circular cavity in the said one leaf.

An embodiment of the present invention will now be described in more detail, by way of example only, and with reference to the accompanying drawings, in which:

Overview

Figs. 1 and 2 illustrate a hinge according to the present invention, at different positions within its range of motion. The hinge 10 has a first leaf 12 in the form of a simple knuckle for attachment to a first member (not shown in Figs. 1 and 2), such as a door frame. A second leaf 14 is connected with the knuckle 12 at a first pivot connection indicated generally at 16, defining a first hinge axis 18. The hinge 10 also has a third leaf 20 which, in use, is attached to a second member such as a door (not shown in Figs. 1 and 2). The third leaf 20 is connected to the second leaf 14 by a second pivot connection illustrated generally at 22, defining a second hinge axis 24, spaced from the first axis 18. The two hinge axes 18, 24 are parallel. Fig. 1 shows the third leaf 20 folded down against the second leaf 14, during a phase of the motion in which the second leaf 14 is pivoting relative to the first leaf 12. Fig. 2 shows the second leaf 1.4 fully extended from the first leaf 12, and with the third leaf 20 pivoted out from the second leaf 14. Thus, a door attached to the third leaf 20 can move, relative to a frame to which the first leaf 12 is attached, by a motion which involves pivoting about both axes 18, 24, as will become apparent from the following detailed description.

First Pivot Connection The first pivot connection 16 is between the first leaf 12 and the second leaf 14. The first leaf 12 has a single knuckle 26 which provides an internally threaded bore 28. The knuckle 26 is provided with feet 30 for mounting the first leaf 12 on a frame (not shown in Fig. 3), by means of mounting screws at four positions 32. Shim plates 34 may be provided between the first leaf 12 and the frame, if required. The convex outer surface 36 of the knuckle 26, in the region facing the shim plates 34 or frame, is substantially a circular cylinder centred at the centre of the bore 28, which is the axis 18. A retainer 38 is provided between the feet 30, mounted by means of flanges 40 received in short slots 42 in the feet 30, to trap the flanges between the feet 30 and the frame or shim plate 34. Locating pegs 44 further assist in locating and securing the assembly on the frame. The retainer 38 has a concave, circular cylindrical face 46 which faces the outer surface 36 and is centred on the axis 18. A space therefore exists between the face 46 and the outer surface 36, the space being annular when viewed parallel to the axis 18. The other half of the first pivot connection is provided by the second leaf 14, which has two knuckles 50 between which the knuckle 26 is received. An elongate hexagonal-section pin 52 is provided through the knuckles 50 and the bore 28, to serve as a hinge pin for the first connection 16, defining the first pivot axis 18.

Additional features of the pivot connection 16 relate to adjustment of the connection and will be described in more detail below.

Second Pivot Connection

The knuckles 50 are provided at one end of arms 54 which are held apart by a plate 56. At the other end of the arms 54, the arms 54 form knuckles 58 of the second pivot connection, between the second leaf 14 and the third leaf 20.

The third leaf 20 has a single knuckle 60, having end faces 62 in which cylindrical bores 64 are provided.

Hexagonal sockets 66 in the knuckles 58 each receive a bush 68. Each bush 68 has an externally hexagonal projection 70 for receipt in a socket 66. This prevents the bush 68 from turning in the socket 66. The bush 68 also has a cylindrical bore 72, and a circular bearing flange 74. With a bush 68 installed in each bore 64, the knuckle 60 of the third leaf 20 can be located between the bearing flanges 74, and the second pivot connection 22 completed by installing pivot pins 76 to be located in the bores 64, 72. Installation of the pins 76 is achieved when the third leaf 20 is closed against the second leaf 14, exposing a slot 78 (Fig. 4) in the rear of the knuckle 60, allowing the pins 76 to be introduced transverse to the axis of the bores 64 and then moved axially outwardly, through the bores 64, to engage the bushes 68.

The pins 76 are prevented from withdrawal by a block 80 introduced into the slot 78 after the pins 76 have been moved into their final position (see Fig. 4).

Pivot Locking Arrangements

Locking arrangements are associated with each of the pivot connections 16, 22. It is convenient first to describe the lock arrangement associated with the second pivot connection 22.

The lock arrangement for the second pivot connection 22 includes a finger 82 at the free end of the third leaf 20. The finger 82 is curved to have an annular shape when viewed parallel with the axes 18, 24. Moreover, the finger 82 is shaped to be centred on the first axis 18 when the third leaf 20 is folded down against the second leaf 14 (the position illustrated in Fig. 1). Furthermore, the radii of the convex and concave faces of the finger 82 are chosen to allow the finger 82 to enter the annular space between the knuckle 26 and the retainer 38, as the second leaf 14 pivots relative to the first leaf 12. Thus, as the third leaf 20 closes toward the second leaf 14, from the position shown in Fig. 2, the finger 82 first approaches the mouth of the annular space and then, as the second leaf 14 is thereafter pivoted on the first leaf 12, the finger 82 enters the annular space. The finger 82 is thereafter trapped between the knuckle 26 and the retainer 38, thus locking the third leaf 20 against the second leaf 14, preventing pivotal movement about the second pivot connection 22.

This locking of the second pivot connection 22 can only be released by pivoting the second leaf 14 sufficiently on the first leaf 12 to withdraw the finger 82 from the space between the knuckle 26 and the retainer 38. The lock associated with the first pivot connection 16 incorporates a plunger 84. This is slidably mounted against the plate 56 by means of a fixing plate 86 which is, in turn, attached to the arms 54 by fixing screws 88. Thus, the plate 86 is fixed relative to the second leaf 14, but the plunger 84 is able to slide relative to the second leaf 14, being guided in this movement by a lug 90 on the plunger 84, running in a slot 92 in the plate 86.

A wall 94 is formed across the plate 56 and a compression spring 96 is located between the plunger 84 and the wall 94, to urge the plunger 84 toward the axis 18 of the first pivot connection 16.

The plunger 84 thus forms a bolt biased toward the first leaf 12, but retractable against the action of the spring 96.

The knuckle 26 of the first leaf 12 has a groove 98 formed in its outer surface, only the end of which can be seen in Fig. 3. The groove is elongate, extending parallel with the axis of the first pivot connection 16. One side of the groove 98 is in the form of a radial step 100.

The leading edge of the plunger 84 has a sharp edge 102 merging with a guide surface 104. Consequently, as the second leaf 14 pivots from the position of Fig. 1 toward the position of Fig. 2, any contact with the knuckle 26 will cause the plunger 84 to ride across the outer surface of the knuckle 26 until the edge 102 passes the edge of the groove 98, drops down the step 100 by virtue of the biasing of the spring 96, and is thereafter trapped against pivoting in the reverse direction, by engagement between the plunger 84 and the step 100.

This lock may be released by drawing the plunger 84 out of the groove 98, against the action of the spring 96. In order to effect this withdrawal, the third leaf 20 is provided with cam fingers 106 which penetrate cam recesses 108 in the plunger 84, through slots 110 in the plate 86. Sloping faces of the fingers 106 and recesses 108 engage to provide a cam action which pulls the plunger 84 away from the axis 18, against the bias of the spring 96, as the third leaf 20 closes toward the second leaf 14. Consequently, once the third leaf 20 has fully closed against the second leaf 14, the plunger 84 is fully withdrawn from the groove 98 and the first pivot connection 16 is released.

The Pivot Connections and Lock Arrangements In Use

The interaction of the two pivot connections 16, 22 and their associated lock arrangements can now be described sequentially with reference to Figs. 5 to 10. These drawings illustrate the hinge 10 in use with a door 112 formed of an edge profile 114 and a door panel 116, which may be a sealed glazed unit, for example. A door frame 118 is provided in an aperture 120 in brickwork 122. The hinge 10 connects the door 112 to the door frame 118.

It is evident from Figs. 5 to 10 that the door frame 118 is set back from the external face 124 of the brickwork 122. It is readily apparent, for example from Fig. 5A, that in a conventional arrangement providing a single pivot axis between the door 112 and the frame 118, such as at the axis 18, the range of movement of the door 112 would be limited by abutment with the brickwork 122. However, this problem is not encountered in the arrangement illustrated in Figs. 5 to 10, as will now be described. Fig. 5 illustrates the door 112 in the fully closed position. The first leaf 12 is attached to the frame 118. The third leaf 20 is attached to the edge profile 114 and is closed against the second leaf 14, so that both the second and third leaves 14, 20 lie against the outer face of the door 112. The first leaf 12 is directed generally at right angles to the plane of the second and third leaves 14, 20. In this position, the finger 82 (Fig. 5B) is trapped between the knuckle 26 and the retainer 38, thus locking the second pivot connection 22, to prevent the third leaf 20 pivoting away from the second leaf 14.

However, the first pivot connection 16 is unlocked, as can be seen from Fig. 5C, which shows the cam fingers 106 in the recesses 108 and thus engaging the plunger 84 to hold the edge 102 away from the knuckle 26. Thus, subject to any other locking arrangements which may be provided elsewhere on the door, the door 112 is free to move from the closed position (Fig. 5A) by pivoting about the first pivot axis 18, since the door 112 must move with the second leaf 14, as the second pivot connection 22 is locked as described above.

As the door begins to open, a first intermediate position is reached, as shown in Fig. 6. The door is approximately one quarter open, having moved through approximately 45° of a total available movement of approximately 180°. As can be seen from Figs. 6B and 6C, the second pivot connection 22 remains locked in this position, because the finger 82 remains trapped between the knuckle 26 and the retainer 38. This position thus holds the third leaf 20 against the second leaf 14, causing the fingers 106 to hold the plunger 84 retracted from the knuckle 26, thus keeping the first pivot connection 16 in its unlocked condition. As the door 112 continues to open, the half open position illustrated in Fig. 7 is reached. The door 112 has now turned through approximately 90°. All of this motion has been centred at the first axis 18.

Fig. 7B shows that at this position, the finger 82 is just moving clear of the retainer 38. Consequently, as this position is reached, the lock of the second pivot connection 22 is released. The third leaf 20 is therefore freed to pivot away from the second leaf 14, about the second pivot connection 22, as will be seen in Fig. 8.

It is to be noted that as the position of Fig. 7 is reached, prior to any movement of the second pivot connection 22, the plunger 84 remains withdrawn by action of the fingers 82, so that the first connection 16 remains unlocked.

The half open position of Fig. 7 represents an extreme position of the first pivot connection 16, by virtue of abutment of an edge 126 of the plate 56 against a shoulder 128 on the knuckle 26. This abutment prevents the first pivot connection 16 moving beyond the 90° position of Fig. 7.

Although the first pivot connection 16 is prevented from further movement (thus preventing abutment of the second leaf 14 with the brickwork 122), the door is still free to turn further, as can now be understood with reference to Fig. 8. As has been noted above, the finger 82 has moved clear of the retainer 38 to release the lock on the second pivot connection 22. Thus, although the first pivot connection 16 cannot further pivot, the third leaf 20 is now free to pivot relative to the second leaf 14, by means of the freed second connection 22, thus allowing the door 112 to move past the half way position of Fig. 7, to the position of Fig. 8. As it does so, the third leaf 20 moves away from the second leaf 14, withdrawing the fingers 106 from the recesses 108. This releases the plunger 84 which is thus driven by the spring 96 to advance into the groove 98, so that the edge 102 engages the step 100. This leaves the first pivot connection 16 locked against further movement in either sense. Further movement in the anti-clockwise direction (as shown in the drawings) is prevented by the plunger 84 abutting the step 100, whereas further movement in the clockwise direction (as shown in the drawings) is prevented by abutment of the edge 126 against the shoulder 128.

The second pivot connection 22 is, however, now entirely free to pivot, allowing the door to open toward the three quarter position of Fig. 9, in which the door has turned through approximately 135°. The first pivot connection 16 remains locked when the door is in this position. In due course, the fully open position of Fig. 10 is reached, in which the door has turned through approximately 180° and the edge profile 114 is now abutting the knuckles 58, limiting further outward opening of the door 112. Again, it can be seen from Fig. 10A that the first pivot connection 16 remains locked.

The total movement achieved by the door 112 is through approximately 180°, the first 90° about the first axis 18, and the second 90° about the second axis 24. During the first half of this movement, the second leaf 14 swings out to position the second axis 24 further away from the frame 118, reaching out sufficiently to allow the door 112 then to turn about the second axis against the external face 124 of the brickwork 122, but without abutment with it. In order to close the door from the fully open position of Fig. 10, a user will pull on the door to swing it from the position of Fig. 10. Since the first pivot connection 16 is locked, the door 112 will initially swing about the second axis 24, moving back through the three quarter position of Fig. 9, to the position of Fig. 8 and then to the half open position of Fig. 7. As this position is reached, the fingers 106 enter the recesses 108 to withdraw the plunger 84 and unlock the first connection 16, but the finger 82 moves against the knuckle 26, ready to enter the gap between the knuckle 26 and the retainer 38. At this one position, a transition occurs in which both pivot connections 16, 22 are instantaneously released but it is to be noted that immediately the door 112 continues to move to its closed position, the finger 82 enters the annular space to be locked between the retainer 38 and the knuckle 26, locking the second connection 22. Alternatively, if the door is moved back toward the full open position from the half open position of Fig. 7, the plunger 84 is released to lock the first pivot connection 16. Thus, whichever way the door is moved from the half open position of Fig. 7, one or other pivot connection 16, 22 becomes locked.

If the door is being closed, the door continues to move from the half open position through the quarter open position of Fig. 6, toward the fully closed position of Fig. 5. During this movement, the second connection 22 remains locked.

Adjustment

The hinge shown in the drawings includes various arrangements for adjustment, particularly to allow the door 112 to be correctly aligned within the frame 118. Separation between the door 112 and the door frame 118, transverse to the axes 18, 24 is provided by adjustment between the third leaf

20 and the door 112. A plate 130 is provided between the third leaf 20 and the edge profile 114, with locking screws 132 passing through the third leaf 20 and the plate 130, into the edge profile 114. The screws 132 pass generally transverse to the second axis 24, but spaced from it. A lug 134 on the plate

130 has an internally threaded bore 136 and is located in a channel 138 (Fig.

4) in the face of the third leaf 20. An adjustment screw extends through the knuckle 60 in a direction perpendicular to the second axis 24 and to the screws 140, to engage the bore 136 and thus allow the plate 130 to be moved toward or away from the second axis 24 by turning the screw 140, thus moving the door 112. When the door is correctly positioned in this direction, the locking screws 132 can be tightened down. Further adjustment is provided within the first pivot connection 16. This allows the door position to be adjusted parallel with the axes 18, 24. It is first necessary to describe the first pivot connection 16 in more detail.

The pin 52, which forms the primary pivot pin of the first connection 16 is hexagonal in section and carries a sleeve 142 which has a hexagonal central bore 144 and an externally threaded surface 146. The sleeve 142 is located within the internally threaded bore 28 of the knuckle 26 so that turning the sleeve 142 relative to the knuckle 26 by turning the pin 52 will cause the sleeve 142 to be drawn along the bore 28.

In the assembled arrangement, the ends of the pin 52, beyond the knuckle 26, carry bushes 148 which have a hexagonal internal passage fitting the pin 52, and cylindrical outer surfaces. The bushes 148 are received in cylindrical concavities in caps 150, so that the pin 52 can turn in the caps 150. The caps are in turn located within the knuckles 50 of the second leaf 14 and are secured in position by grub screws through the knuckles 50, to engage annular channels 152 in the caps 150.

When the hinge is being assembled, one end of the pin 52 is installed, as described, with the bush 148 and cap 150. At this stage, the bush 148 and cap 150 at the other end of the pin 52 are not installed. Preferably, in the normal situation with vertical hinge axes at the side of a door, it is the upper end of the pin 52 which is left exposed at this point. The hexagonal section of the pin 52 allows the pin 52 to be turned. This causes the sleeve 142 to move up or down the bore 28, including moving the upper end of the sleeve 142 up to project above the knuckle 26, so that the upper knuckle 50 rests on the upper end of the sleeve 142, at a height determined by the position of the sleeve 142 in the bore 28. Thus, turning the pin 52 allows the height to be adjusted. Once the correct height adjustment has been achieved, the bush 148 is placed over the upper exposed end of the pin 52, the cap 150 is put in place and secured by a grub screw.

The thread on the sleeve 142 preferably has a formation, such as a prominence, which cause slightly increased friction with the bore 28, so that during normal use of the hinge, the sleeve 142 will tend to turn with the bore 28 rather than relative to it. This avoids the height being adjusted by normal use.

Security It can be seen from Fig. 11 that when the door is fully closed, the grub screws 154 face the door frame 112 to prevent tampering. Tampering with the pin 52 is prevented by the caps 150 (and by close proximity of the brickwork 122 which hinders access for tools). The second pivot connection 22 is protected against tampering by the sockets 66 being blind, so that the pins 76 are not accessible from outside the hinge 10.

Concluding Remarks

Many variations and modifications can be made to the apparatus described above, without departing from the scope of the present invention. In particular, many different shapes, sizes arid relative shapes and sizes could be envisaged for the hinge described, and other arrangements could be envisaged for adjusting the hinge and for providing locking within the pivot connections. In addition, it is envisaged that the adjustment arrangement described in relation to the first pivot connection could be used in a simple hinge having only two leaves connected by a single pivot axis.

Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
