Description
A connecting-rod mount which can be installed concealed in the rabbet of windows doors or the like
The invention relates to a connecting-rod mount which can be installed concealed in the rabbet of windows, doors or the like, having the features of the preamble of Claim 1.
Connecting-rod mounts of this type are known in many different forms of execution. Thus for example DE-PS 36 06 487 shows a mount with which the connecting rod has, on its sides facing the covering rail. a peripheral cam which is for supporting the connecting rod from the underside of the covering rail and travels from the area of the longitudinal slit under the connecting rod. By this means a closure peg can be used which in the locking position protrudes further into the rabbet and through the supporting of the connecting rod from the underside of the covering rail is partially sunk into the rabbet groove in the open position or unlocking position so that in spite of its relatively large dimensions the closure peg does not form an obstruction in the way during the normal operating movements of the connecting-rod elements.However this embodiment requires that there is sufficient room under the covering rail in the rabbet groove for supporting the connecting rod from the underside of the covering rail and for receiving the extended closure peg. As a rule this is also the case with normal rabbet grooves.
There are however numerous instances of application in which the depth of the rabbet groove receiving the connecting rod is very small or is even completely absent, because e.g. there is in the rabbet surface only one groove sufficient to receive the covering rail. In some instances this groove can also be absent. The invention sets out to remedy this and to make possible a secure and strong locking when both the rabbet groove and the rabbet itself are small in dimension.
This problem is solved by the theory of Claim 1.
The hook-shaped end of the locking part, which end projects in the direction of movement, is the piece of this part which projects far enough into the rabbet for a secure engagement with the closing part, even in the event of any tolerances in the rabbet width. By means of a simple, controlled rotating movement of the locking part dependent on its sliding movement into the unlocking or open position, the extent by which the locking part protrudes from the outside of the covering rail into the rabbet is considerably reduced, namely by approximately up to half. In addition the new solution does not require any additional stowing space below the sliding plane of the connecting rod. The new connecting-rod mount is therefore not dependent on a particular form or depth of the rabbet groove.
Moreover the arrangement is also extremely simple, since the individual parts can be constructed as punched parts or stamped parts. Assembly is also simple since no particular bearing or securing elements are required.
The locking part can also be constructed to be very strong. Above all however the possibilities of opening this mount by force when it is locked are also very greatly restricted. It is not possible to widen the rabbet to cancel the locking position since the hook-shaped section of the locking part grips the closing part behind. A rotating movement or an axial movement of the locking part in relation to the connecting rod is also not possible without displacement of the connecting rod.
Further essential features and developments of the connecting-rod mount in accordance with the invention are the subject matter of the subclaims.
The invention is explained in more detail below using a plurality of embodiments and with the aid of schematic drawings in which:
Figure 1 shows a topview of the connecting-rod mount
in accordance with the invention. partially
sectioned and viewed parallel to the plane of
the leaf;
Figure 2 shows, in a similar representation to Figure
1, the mount in the locking position;
Figure 3 shows on a larger scale and as a cut out
section, a part of the mount in longitudinal
section, the locking part being in the
locking position:
Figure 4 shows the same representation as in Figure 3
with the locking part in the unlocking
position;
Figure 5 shows a topview onto the mount in accordance
with Figure 3 and
Figure 6 shows a modified embodiment in the same
representation as Figure 3.
The Figures show the mount in its installated position, leaf frames and transom frames not being shown in order to simplify the representation. It is assumed that the closing part is securely arranged on the transom frame and the mount is arranged on the leaf frame, there being between both frames an appropriate rabbet (leaf rabbet) in which the parts come to lie because of the concealed installation. It is further assumed that a plane groove is moulded, on the rabbet side, in the leaf, which groove is just sufficient to receive the connecting rod and/or covering rail.
The mount 1 shown in Figures 1 and 2 has an operating device 2 with an operating handle 3 and a drive part 4, which drive part is in engagement with the connecting rod 5 in order to diplace the latter in one or the other direction depending on the rotation of the operating lever 3. The connecting rod 5 is displaceably guided on the underside of a covering rail 6, which is secured to the leaf frame e.g. by screws, with the help of guiding parts such as the rivet pins 8 which reach through appropriate slits or longitudinal apertures in the covering rail 6.
Closing parts are secured to the transom frame at certain points of the rabbet. In the depicted embodiment these closing parts are composed of parts securely screwed on the transom frame. which parts have, viewed in the longitudinal direction of the rabbet, a U-shaped or housing-like cross-section which is closed towards the rabbet.
In the longitudinal direction of the rabbet, offset in relation to the closing parts 7, elongated covering elements 9 are arranged on the covering rail 6 securely arranged on the leaf frame. Viewed along the leaf rabbet these covering elements are also closed towards the rabbet and constructed with a U-shaped or housing-like cross-section. The housing-like closing parts 7 and the coverings 9 are open in the rabbet longitudinal-direction in the areas projecting into the rabbet.
In the depicted example each covering 9 consists e.g. of an appropriately formed punched part 10 on which the front edges, which are directed in the rabbet longitudinal-direction, of the two legs are constructed in a stepped manner, in fact in such a way that each covering 9 can, from the underside of the covering rail 6, be inserted through an appropriate aperture (longitudinal slit 20 in Figure 3), the stepped areas resting against the aperture edges to secure the position of the covering 9 or gripping the covering rail below in order to limit the insertion of the covering 9 into the aperture in the direction of the rabbet. As emerges from Figures 3 and 4, the legs 21 resting on the longitudinal edges of the aperture 20 can slightly project under the underside of the connecting rod 5 by an amount 23, in order in this manner to keep the connecting rod at a slight distance from the securing plane of the leaf frame and to reduce the friction resistance.
In the area of the connecting rod 5 which remains during the sliding movements in accordance with the arrow V (in Fig. 3), the connecting rod has a driving recess 25 into which the narrowed end 12 of a bend on one end of a closing part constantly engages with play.
In the process the bend of the closing part 15 passes through the longitudinal aperture 20 of the covering rail 6. The bend is on the end of an elongated, oblong, straight main-section of the locking part 15 whose other end is connected, via a transition section, to a hook-shaped locking section 13 projecting into the rabbet.
The arrangement is made in such a way that when the main section of the locking part 15 is, as shown in Figure 2, ocientated approximately parallel to the covering rail 6, the closing part lies, with the exception of the driving end 12, completely on the surface of the covering rail 6 and supports itself on the latter, while the hook-shaped locking section 13 projects into the leaf rabbet by a maximum amount, in fact so far that during displacement of the connecting rod 5 it can if necessary come, via an upward slope 13a, into an gripping-behind engagement with the closing part 7, as shown in Figure 2.
In the unlocked position, which is shown clearly in
Figures 1 and 4, the locking part 15 is, during the sliding movement, rotated about an axis lying diagonal to the displacement direction V. In the process a piece of the main section together with the transition section of the closing part descends into a recess. namely the longitudinal aperture 20 in the covering rail 6. By this means the extent by which the locking part projects in its locking position into the rabbet is substantially reduced.This extent of projection can be reduced still further by, as shown in Figure 3 and 4, a slit or a longitudinal aperture 26 also being provided in the connecting rod 5, which slit or longitudinal aperture comes, during movement of the connecting rod into the unlocking position; into such an alignment with the longitudinal aperture 20 of the covering rail 6 that the transition section 17 of the locking part can be lowered right into the recess 26 in the connecting rod 5.
The locking part 15 is under no initial stress. Its rotating movements are forcibly controlled dependent on the displacement movements. For the rotating movement from the position in accordance with Figure 3 into the position in accordance with Fig. 4, on the one hand the front end 27, which is facing the closing part 7, of the covering 9 cooperates with the hook-shaped end of the locking part and on the other hand the transition section coperates with the narrow end 19 of the recess 20 of the covering rail 6. The latter two only permit a lowering movement after a sufficiently long displacement in the direction of the unlocking position, so that the hook-shaped end of the locking part can definitely pull itself out of the engagement with the closing part 7 before the tilting movement starts.As soon as the front end 27 of the covering 9 makes contact with the hook section, the connecting rod 5 has been displaced so far that the transition section is in alignment with the longitudinal aperture 20 and can descend into the latter. During this descent, the transition section also finally comes into the aperture 26 of the connecting rod. which aperture is in constant alignment with the transition section of the locking part.
During the opposite movement, the transition section of the locking part 15 makes contect with the narrow side 19 of the aperture 20 of the covering rail 6. At this moment the hook-shaped section comes free from the front end 27 of the covering 9, so that because of the inclined slope of the transition section the hook-shaped section can be lifted from its lowered position in accordance with Fig. 4 into the position in accordance with Figure 3.
As shown, to improve the control effect an inserted or moulded-on control rib 17 can be provided, on the underside, in the transition section of the locking part 15, which control rib 17 cooperates, in the manner which can be seen from Figures 3 and 4, with the narrow side 19 of the aperture 20 and the upper side of the cover rail.
In addition to an ascending slope 13a (Figure 2) on the underside of the hook-shaped end 13 of the closing part, an appropriate, slightly protruding control nose 35 can also be provided in the area of the controlled narrow side of the aperture 37 in the covering rail, as shown in Figure 6. With this embodiment the transition area is given the reference numeral 33, the hook-shaped section 32. the control rib 34. the control edge of the covering 30 is given the reference numeral 31 and the driving attachment of the locking part is given the reference numeral 36.
