Abstract

A gear mechanism for side/bottom-hung doors for displacing push rods of a side/bottom fitting to a rotational position, a tipping position and a locking position comprises, in addition, a latch (9) guided within gear box (4) and capable of being retracted against spring force (10). A handle socket (11) is, in respect to a gear wheel (16) of the gear wheel driver, arranged for angular lost motion in an angle corresponding to the angle of rotation of the door handle (18) for operating the latch. In the lost motion zone of handle socket (11) a cam (19) of handle socket (11) runs up on to a guide face (20) of an angled two-arm latch lever (21), which retracts latch (9). A second cam (28) is provided in the region of tipping position on a disc (13) fixed to the socket so that latch (9) is also retracted in the tipping position. The rack and gear mechanism comprises a gear wheel (16) with two gear rim segments (26, 29) of different diameter and a stepped rack (17). The gear wheel with larger diameter (26) acts during actuation of the handle to the locking position, and the gear wheel of smaller diameter (29) to the tipping position. <IMAGE>

Description

9 1 FBS/4450 GEAR MECHANISMS FOR SIDE/BOTTOM-HUNG DOORS The invention
relates to a gear mechanism for side/ bottom-hung doors intended to displace push rods of a side/bottom fitting to a rotational position in which all locks are released, to a tipping position in which a set-out shear swivels outward and a pin engages a swivel bearing as well as to a locking position in which all locks are closed, whereby, within the gear box, a gear wheel capable of being actuated by means of a handle engages at least one rack, as well as, if required, a cylinder lock blocking at least one of the positions.
Gear mechanisms of this type are very common with side/bottom-hung windows and doors. With side/bottomhung doors, for instance balcony doors, an additional catch is frequently fitted, which enables, with a rotational position set, a door to be kept in the closed state while one is on the balcony. As such it would be desirable if also a side/bottom- hung door could function as an entrance door in every way. Apart from the side/ bottom fittings with their gear mechanisms multiple-bolt locks are known, which however are not suitable for operating a side/bottom fitting. They have a locking position, usually brought about by turning the door handle upward and via the normal horizontal position, with the downward handle stroke against the spring of the handle socket following, with a view to actuating the latch.
It is the object of the invention to overcome this disadvantage.
According to this invention there is provided gear mechanism for side/bottom-hung doors for displacing push rods of a side/bottom fitting into a first rotational position in which all the locks are released, into a tipping position in which a set-out shear swivels outward and a pin engages a swivel bearing, and into a locking position in which all locks are engaged, comprising a gear wheel capable of being actuated by means of a handle, rack means in engagement with the gear wheel, a latch capable of being retracted against the force of a spring by a driving element connected to be operated by the handle, said driving element further operating said gear wheel through a lost motion connection which limits the movement of the driving element relative to the gear wheel in both directions, whereby movement of the driving element within the limits of the lost motion operates said latch and, beyond the limits of the lost motion in opposite directions from its position corresponding to said first rotational position, moves the gear wheel to operate the rack means into the tipping position and the locking position respectively.
In a preferred embodiment, there is disposed in the gear box for the side/bottom fitting an additional latch capable of being retracted against the force of a spring, whereby said latch can be actuated by the handle designed as a door handle within a disengaged zone of a gear wheel drive, said zone corresponding to the stroke of the latch. Accordingly, in the rotational position of the door leaf, the latter is initially kept in the locking position by the latch. If the door handle is pressed slightly downward, the latch is retracted and the door can be opened. If the door is closed, the latch is again retracted into the striking plate in the frame of the door or in its stationary leaf. BY turning the door handle beyond the angle of rotation for 0 actuating the latch, i.e. by 90 to the vertical position, the locks are closed with the latch projecting. If the door handle is moved 180 0 upward to the tipping position of the leaf, the corresponding locks are opened and the latch is retracted. Only the swivel bearing engages.
C As distinct from the handle of an ordinary side/bottom fitting, the door handle is also on the outside of the door. Hence it will be advisable to install a lock, in particular a twin-cylinder lock, for locking the positions of the side/bottom fitting. A particularly advantageous embodiment of the subject of the invention is characterised by the fact that the door handle engages a handle socket carrying the driver which is freely movable so as to permit disengagement between lo stops of the gear wheel in an angle corresponding to the handle angle for actuating the latch, and in that a cam is connected with the handle socket, which is opposite a guide face of one of the lever arms of a latch lever, in particular an angled lever, whereas the other lever arm of said latch lever engages the latch, causing it to be enables, in simple manner, decoupling from the gear wheel with a view to during conventional operation of oves between the stops, fitting remain cam, on the other hand, pushes the sideways and, as a result, actuates the load arm of which acts on the latch; the retracted. In this connection it is advantageous for the guide face to have a section projecting into the path in which the cam moves, the length of said section corresponding to the angle of disengagement between handle socket and gear wheel. The cam raises the force arm of the lever to the extent in which the guide face on the force arm dips into the path curve of the cam. The guide face comprises a projection which, once its peak has been reached, drops off again. This causes the latch within range of the guide face to be retracted to the maximal extent, but slowly released if the door handle which serves as a displaced. This of the handle socket actuating the latch, the handle. While the driver m the push rods of the side/bottom stationary. The guide face lever, the latter is handle of a side/bottom fitting is turned downward into its vertical position.
It is advisable for a second cam offset in relation 0 to the first cam by at least 90 to be connected with the handle socket, whereby the guide face is located within the rotational range of said offset cam and said offset cam makes contact with the latch in order to retract it, whenever the handle socket is turned to the tipping position. This ensures that the latch is retracted not only in the rotational position of the door but also in the tipping position, and the tipping movement is, accordingly, not prevented. By way of cams, use may be made of low-friction roller bolts.
A preferred embodiment is characterised by the fact that with a view to transmitting a spring force to the handle socket within range of the handle angle in the rotational position of the handle, a spring-loaded link engages a projection of the handle socket, in that the link is displaceably located in a position approximately radial in respect to the handle socket, and in that the front face of the link intersects the path of the handle socket from the rotational position of the door handle to the amplitude of the approximately radial displacement stroke of the spring-loaded link corresponds at least to the handle angle for actuating the latch. When the handle socket is turned, the projection of the handle socket, for instance a roller pin, runs on to the link and raises it against spring force radially in relation to the axis of rotation of the handle socket, as a result of which the action of a handle socket spring is brought about while the driver moves between the stops of the gear wheel, and is therefore still disengaged in respect of the side/bottom fitting's push rods. When the door handle is actuated one notices the effect of the spring as with any conventional entrance door. Once the maximum effect of the spring force has been exceeded, there follows spring-assisted further turning of the handle to the 5 locking position.
Another, especially advantageous embodiment provides for the driver, the first and second cams and the projection to be arranged on a disc made integral with the handle socket or connected with the latter in a non-rotating manner, and in that the gear wheel is rotatably located on the same axis as the handle socket but opposite the latter. In this way all control elements are concentrated in one component. In this connection it is advantageous for the driver to project from the disc in the axial direction and to engage a recess in the gear wheel so as to bring about mutually limited disengagement of the rotational motion. Furthermore, a simple and at the same time particularly precise embodiment is characterised by the fact that, with a view to achieving identical displacement strokes of the push rods in spite of a door handle stroke which 0 compared with the 90 actuating stroke approximately to the tipping position is reduced by the angle of rotation for operating the latch, the gear wheel has two peripherally adjacent gear segments of different radius, and in that the rack has a serration with a progressive ratio corresponding to the difference between the radii of the gear wheel. As a result, also the remaining rotation of the door handle to the locking position, which has been reduced by the angle for operating the latch, causes the push rods to carry out the same, full displacement stroke as rotation of the door handle by 0 90, from the rotational position to the tipping position.
m An embodiment of the invention is shown in the drawings, in which:
Figure 1 shows a view of a gear mechanism for side/bottom-hung doors with the cover of the gear box removed, and Figure 2 is a schematic diagram showing the handle or door handle positions.
3 of a side/bottom fitting can be lock case front, to three position gear mechanism contained in gear Push rods 2 displaced, along a with the aid of a 4. Figure 2 shows the corresponding positions of handle designed as door handle 5, i.e. the rotationa position 6, the tipping position 7 and the locking position 8. In addition, a latch 9 is located in gear box 4, whereby said latch can be retracted against the force of a spring 10.
The gear mechanism comprises a handle socket 11 with square cut-out 12 for door handle 5. Handle socket 11 or a disc 13 connected with said handle socket supports a driving pin 14 which engages a recess 15 in a gear wheel 16. This gear wheel 16 serves to displace a rack 17 connected with push rods 2, 3. During a rotational movement of handle 5 or handle socket 11, respectively, in the course of which driving pin 14 moves within recess 15, gear wheel 16 remains in the rotational position as drawn. This rotational movement, during which there is disengagement between door handle 5 and push rods 2, 3 (or handle socket 11 and gear wheel 16) corresponds to a handle angle 18 (Figure 2), the magnitude of which is that of the conventional door handle angle of a mortice lock for actuating the latch.
On disc 13 of handle socket 11 there is also a first cam 19 which abuts a curved guide face 20 of box a 1 force arm of latch lever 21 which is designed as an angled lever. If handle 5 is pressed down (angle 18), cam 19 pushes guide face 20 downward and load arm 22 of latch lever 21 presses latch 9 back against the force of 5 spring 10.
Handle socket 11 or its disc 16 also comprises a proJection 23 against which abuts a link 24 capable of being displaced against the force of a spring 25 radially in respect of the axis of rotation of handle socket 11. The force of this spring must be overcome when actuating handle 5 in angle zone 18.
If handle 5 is turned further to position 8, the driving pin 14 actuates gear wheel 16, after moving along recess 15. Gear segment 26 engages serration 27 of rack 17, causing it to be displaced to the locking position of the side/bottom fitting. At the same time cam 19 passes beyond a peak of guide face 20, as a result of which latch lever 21 returns to its initial position. This causes latch 9 to resume the position shown in Figure 1. In the locking position 8 of door handle 5 the side/bottom fitting is therefore locked and the latch projects.
0 If door handle 5 is turned upward by 180 to tipping position 7, a cam 28 on gear wheel 16 slides up on to guide face 20 of latch lever 21 actuating the lever to retract. In the tipping position of handle 5 latch 9 remains in the retracted position. At the same time as handle 5 is moved from position 6 to position 7, a second gear rim segment 29 of gear wheel 16 engages teeth 30 of rack 17. As a result, the push rods 2 and 3 are moved to the unlocking position of the side/bottom fitting, at the same time as latch 9 is retracted.
Gear rim segments 26 and 29 have different pitch circle diameters. and the respective sets of teeth 27 and 30 of rack 17 are located in different planes.
This ensures that when gear 16 is turned to the locking position of the side/bottom fitting, i.e. according to Figure 2 by an angle of 90 0 (position 6 to position 8) less angle 18 for the lost motion of the handle, the displacement stroke of rack 17 is the same as that by rotation of the gear wheel by 90 0 to the tipping position (position 6 to position 7). Thus, the angle of rotation for the tipping function, which is reduced owing to disengagement for operating the latch, is lo compensated so that the distance by which the push rods are displaced from the rotational position to the tipping position corresponds, as is common with side/bottom fitting, exactly to the length of the displacement stroke between the rotational position and the locking position.
A ball catch 31 engages rack 17 or an arm of the latter and defines the end of the handle stroke when moving the latch beyond angle 18. The front face 32 of spring-loaded link 24 may similarly be provided with a recess or a shoulder by way of a passable stop for projection 23. In this way the end of latch actuation (angle 18) can be felt when rotating the handle, while indicating the transition to locking position 8. if front face 32 is inclined towards the circular path of projection 23, a constant reaction can be achieved in spite of the fact that handle angle 18 increases. Front face 32 may be curved and in particular may be in the form of a circular arc. The reaction felt when actuating the handle can, by appropriate design of front face 32, also be adjusted in such a way as to increase progressively.
