Description

The invention relates to an operating handle according to the preamble of Claim 1.

Such a device is known from US-A-4 063 763.

For locking windows and doors that are not inside but after are usually opened with fittings with a Swivel bolt mounted rotatably in a stop body, which extends from the side the stop body can be swung out and in the closed position with a corresponding one Strike plate or striker in the window or door frame can be locked. The bolt is non-rotatably by means of a square pin or attachment on the axis of a handle, which in turn is axially fixed-rotatable in the Stop body is mounted. Above the swivel lock is on Handle head of the handle a side approach, which as a wing or nose on Lock part a little open ventilation position of the window or the door allows. In general, the handle is at an angle to the closed position elongated stopper body arranged for better accessibility on To achieve window frames.

Burglary attempts have shown that such constructions do not offer sufficient strength and security against break-ins. Through strong pulling Compressive forces that, for example, perpendicular to the window plane on the Lock bolts can be exercised, strong deformations of the locking elements occur. If the locking bolt is bent, it can come out of the Pull out the striking plate and the window can be opened freely.

The invention aims to remedy this and against further disadvantages of State of the art. Accordingly, the main object of the invention is to create it an improved actuation handle with compact overall dimensions significantly improved resistance to tensile and compressive forces having. The fitting should also be simple and inexpensive to manufacture his.

Main features of the invention are in the characterizing part of claim 1 specified. Refinements are the subject of claims 2 to 6.

With an operating handle for windows, doors or the like. with a stop body, which on a screw-on surface e.g. a window or door leaf profile can be fastened and with a handle that has a handle neck on the stop body is axially fixed / rotatable and inside the stop body is in functional connection with a locking element, the locking element by operating the handle with a window or door frame side arranged locking part can be engaged, the invention provides according to claim 1 that the locking element as a linearly guided slider is formed, which is mounted longitudinally displaceably in the stop body and engages behind the assigned locking part in the locking position at least in sections. This structure is as simple as it is robust. At the same compact dimensions of the stop body makes it longitudinally displaceable stored bars a significantly improved resistance to tensile and Pressure forces that are exerted on a window or door leaf by force. The positive and non-positive interlocking of bolt and striker also prevents the bolt from sliding out of its locking, which the Fitting stability increases. All components can be designed to save space are and ensure an inexpensive and easy assembly as well permanent reliable usability.

The locking element is laterally in the stop body sliding manner. It therefore always moves in close proximity and parallel to the locking part, so that the length of the slide bolt compared to conventional Swivel bolts can be shortened significantly, which is the stability and the Resistance of the fitting further increased.

The locking element is height and / or pressure adjustable. This enables one extremely simple adjustment of the bolt to the striker. inaccuracies the components, in the assembly or in the window frame can also be balance quickly and easily after years of use, so that always a secure engagement of the bolt in the locking part is guaranteed.

The formation of a longitudinal recess within the stop body is also favorable to accommodate the driver element. This is Space-saving housed in the rosette, whose dimensions are extremely compact can be held.

With the measure of claim 2 you always achieve a safe and smooth Sliding guidance of the bolt within the rosette body, if namely the locking element has sliding or guiding flanks and is form-fitting with them passes through a lateral longitudinal slot of the stop body. For this also contributes to claim 7 by the locking element on a driver element attaches that slidably longitudinally slidable within the stop body is.

A further stabilization of the sliding guide of the locking element is achieved by the configuration of claim 3, according to which the driver element a Has a U-shaped cross-section and a positive fit within the longitudinal recess is slid. The U-legs offer a double if necessary Hold the driver within the rosette, especially if it is on the side Apply shear forces to the transom. A twisting or twisting of the driver element and thus the locking element is reliably prevented. The latter can be in one piece with the driver element, which further increases resistance.

An advantageous further development of the invention ensures the engagement of the bolt in the closing part, by the locking element being essentially L-shaped or T-shaped Has cross-section. This ensures that there is always sufficient hold between the bars and locking part given. The bolt cannot be easily removed from his Pull out the closed position. Alternatively, the locking element after Claim 4 a mushroom head, a mushroom cone, a mushroom tongue, a trunnion or the like. depending on the shape of the locking part.

In order to reliably rotate the handle permanently into a longitudinal movement to be able to implement the locking element, the driver element is coupled to the handle via a gear, the handle neck of the handle carrying a pinion at the end can, which is in engagement with the driver element. Such a construction can be implemented inexpensively and is also easy to assemble.

Alternatively, the driver element can be guided by a link be coupled with the handle. In this case, the handle neck wears the end of the handle advantageously a pin that with the driver element is engaged.

Corresponding to the locking element, the closing part is in line with Claim 5 on the front side an undercut longitudinal recess that has an opening for receiving the locking element.

Another important measure of the invention is in that the locking part carries fastening cams on the back. These ensure a particularly firm and reliable hold of the locking part in the window or Doorframe. At the same time, the mounting of the locking plate on the window considerably simplified. Conventional strikers had to, due to the Arrangement of the swing bolt, embedded in the window or door frame , for which corresponding millings were required. The invention Training the locking part, however, only requires suitable Drilled holes for receiving the cams, which are held in a form-fitting manner, while the striker rests flat on the front of the frame.

Claim 5 also provides that the closing part is adjustable in height and / or pressure is trained. by name this enables simple and precise adjustment of the relative distance between bolt and striker, so that inaccuracies in the components, occur in the window frame or during assembly can. This is always a positive and non-positive engagement of the bolt in the locking part ensures what further improves the security against burglary.

The actuating handle, generally designated 10 in FIG. 1, is a window fitting educated. It has a rosette body 12, which acts as a stop body is generally box-shaped or cap-shaped, and a decorative cover cap 32 for covering or decorating the base body 12. The latter is just like the cover cap 32 with screw holes 36, 37 provided. They are used to hold (not shown) Fixing screws for fixing the rosette 12 to a (not shown) Casement profile.

Another component of the fitting 10 is a handle 40 which can be rotated in an axially fixed manner is connected to the rosette body 12. It has a handle body 42 and a handle head 43, which itself with a stepped handle neck 44 and a square 45 continues. The handle main part 42 can be (indicated) Finger recesses 46 may be provided. A slightly wedge-shaped extension 48 is wing-like on one side at the top of the grip head 43.

As can be seen in FIG. 2, there is a bearing bore in the rosette base body 12 14 introduced. The cap 32 is the same with an opening 34 Diameter provided. The bearing bore 14 takes the handle 40 or the handle neck 44 and is just like this stepped. On protruding from the bearing bore 14 below within the rosette body 12 Square 45 is a ring element 51 placed on one Contact surface 15 is supported at the lower end of the bearing bore 14. A crimp 16 between the square 45 and the ring member 51 secures the axially fixed-rotatable mounting of the handle 40 in the rosette 12, during a rectangular recess 54 in the ring element 51 for a rotationally fixed connection with the handle 40. At the upper, step-shaped end of the bearing bore 14, a guide ring 18 made of plastic or Teflon is used, which is based on the top of the cap 32 supports and with an inner edge in the Hole 14 protrudes. At the lower end of the bearing bore 14 sits between the ring element 51 and the contact surface 15 a slide ring 19. Both ring elements 18, 19 are preferably made of plastic or Teflon and ensure a permanently low-friction rotary movement of the handle 40 in the rosette body 12, 32. The guide ring 18 additionally offers lateral guidance for the handle neck 44.

The ring element 51 rotatably mounted within the rosette base body 12 is designed in the exemplary embodiment as a pinion 50 and carries on the circumference Tooth segment 55, which is in engagement with a rack 60. This is part a substantially U-shaped driver element 62 which is perpendicular upward angled legs 63, 64 in one in the rosette body 12 formed longitudinal recess 20 is mounted to be longitudinally displaceable. The rack 60 is preferably in one piece with the driver element 62 and designed as a lateral leg 63 of the U-shaped element 62. On Longitudinal slot 66 in the bottom of the driver 62 is useful for performing a fastening screw inserted in the central screw hole 37.

The second leg 64 of the rack leg 63 opposite U-element 62 carries a T-shaped protruding outwards at right angles Bolt 70. With its shaft 72, it extends through a lateral longitudinal slot 22 in the rosette body 12 and is by means of a screw 75 on the driver leg 64 attached, which for this purpose has a threaded bore 65. top and The underside 73 of the locking shaft 72 serve within the longitudinal slot 22 as guide or sliding surfaces, while the end faces 76 in the ends of the Longitudinal slot 22 as a stop for the longitudinal movement of the sliding pin 70 serve. The cover cap 32 has a recess 33 on the side, the dimensioning of which the slot 22 of the stop body 12 is adapted.

If the handle head 43 is pivoted on the handle 40 about its pivot axis A, see above this rotational movement over the pinion 50 and the rack 60 in one Longitudinal movement of the driver element 62 implemented. The bolt 70 slides in the longitudinal slot 22 back and forth and - as indicated in Fig. 2 - by its T-shaped head end 78 as a locking bolt with an associated one Locking part 80 are engaged.

This has a substantially flat base plate 82 with a slightly off-center arranged, in cross-section T-shaped longitudinal recess 84 and a lateral inlet opening 85 for receiving the locking bolt 70 the plate 82 carries two cams 87 with screw holes 88 for receiving of (not shown) mounting screws. In addition to that, you can more screw holes 89 may be provided for even greater strength to ensure the screw connection with the window frame.

The locking plate 80 becomes flat at the level of the rosette body 12 on the front side a window frame assigned to the window sash profile (not shown) put on, whereby one the attached attachment cams 87 in suitable (not visible) holes in the frame. This provide the striker with stable lateral guidance while the platen itself is carried over the entire area by the frame. The manufacturing and assembly effort is extremely low, which is particularly a retrofit the fitting, e.g. as part of renovation work.

The longitudinal recess 84 of the locking plate 80 and the longitudinal slot 22 of the Rosette body 12 run parallel to each other in alignment. The entry area 86 of the inlet opening 85 for the locking piece 70 is slightly beveled, to smoothly enclose the latch 70 in the longitudinal recess 84 to ensure.

So that you stop the rotation of the handle 40 and this in can lock at least one functional position is in the handle head 43 of Handle 40 parallel to the axis A of the handle neck 44 with a lock cylinder 49 a (not visible) locking bolt inserted using a key S can be moved back and forth. To accommodate the locking bolt is in the Rosette body 12 or in the cap 32 next to the screw hole 37 introduced a suitable hole 24.

The assembled unit and its function can be seen in FIGS. 3 and 4. It can be seen that the handle 40 obliquely in the locked position (Fig. 3) Rosette body 12, 32 stands for easy handling of the fitting 10 to ensure, the side wing shoulder 48 on the handle head 43 Rosette 12, 32 protrudes laterally. The locking bolt 70 is located on lower stop of the longitudinal slot 22 in the rosette body 12. It is completely with the longitudinal recess 84 of the locking plate 82 in engagement, the T-shaped or mushroom-shaped head end 78 has the recess of opposite design 84 of the locking part 80 engages behind on both sides. That locked in this way Window cannot be opened. Bring the locking bolt of the Lock cylinder 49 also in the locked position, the handle 40 is in the position from Fig. 3 held immovable.

As soon as the locking bolt of the locking cylinder 49 by actuating the Key S is withdrawn from the hole 24, the so unlocked handle 40 are pivoted upward (Fig. 4). The linearly guided Locking bolt 70 slides upward in the longitudinal slot 22 of the rosette 12, 32, until it is level with the inlet opening 85 of the longitudinal recess 84 in the closing part 80 at the other end of the longitudinal slot 22 in the rosette body 12 Stop takes place. Since the side inlet opening 85 of the closing part 80 den Releases the bolt, the window can now be opened to the outside.

The window can also be easily opened in a slightly open permanent ventilation position bring. As soon as the wing-like attachment 48 on the handle head 43 is at the level of the striking plate 80, the handle 40 is pivoted in the closed position back. The side wing shoulder 48 of the Handle 40 in the narrow outer part of the T-shaped longitudinal recess 84 in the locking plate 82. Due to the wedge-shaped design of the approach 48 the window is then held securely in place. If necessary the handle 40 can be actuated in this position by actuating the locking cylinder 49 be locked so that unauthorized opening of the window from the outside also is no longer possible.

Due to the interlocking interlocking of locking bolt 70 and locking plate The window fitting has 82 in comparison to conventional constructions a significantly improved resistance to violent attempts to open it of the window. In particular due to the relatively large cross-section of the shaft of the bolt 70 and its short length are high tensile and Pressure forces are absorbed and transmitted to the locking plate 82 without the pin 70 is torn out. This can hardly be bend; reaching behind the T-shaped head end 78 reliably prevents pulling out of the locking plate 82. This holds the bolt 70 in The closed position is always firmly enclosed and is secured by the cam securely anchored in the frame.

To facilitate the assembly of the fitting 10, the tooth leg 63 is on a suitable location of the driver element 62 slotted (Fig. 1) so that it inserted straight into the longitudinal recess 20 of the rosette body 12 from below and placed on the toothed segment 55 of the fixedly mounted ring element 51 can be. All gear elements, namely pinion 50, rack 60 and driver 62 are therefore immediately engaged. Further assembly effort is not mandatory; the rosette 12, 32 can directly on the window sash to be assembled. This prevents in the longitudinal slot 22 of the rosette body 12 inserted locking bolts 70 a falling out of the driver element 62. Additional cover or securing plates below the Rosette can easily be omitted.

The invention is not restricted to one of the above-described embodiments, but can be modified in many ways. So instead of one Gear 50, 60, 62 as a power transmission unit a link guide provide. For this purpose, the ring element 51, for example by screwing, non-rotatably connected to the square 45 or the handle neck 44. It wears its lower end face one (not shown) arranged off-center Control bolt, which is in a suitable (also not shown) curved Groove engages in the longitudinally displaceable driver element 62. By turning the handle 40, the control pin moves on one Circular path, whereby the positively coupled driver element 62 along its linear guide is moved in the longitudinal direction of the rosette 12, 32. The Bolt 70 fastened to the side of the driving leg 64 slides in the lateral one Longitudinal slot 22 of the rosette body 12 and offers an additional Slide.

Driver element 62 and locking bolt 70 can also be formed in one piece be, which further increases the stability of the entire fitting. Instead of one key-operated lock cylinder 49 can be a push button or Provide rotary lock actuated cylinder. It is also conceivable to install one Child lock (not shown), for example in the form of a spring-loaded Riegel, who before swiveling over a Slider in the handle head must be operated. With a (also not shown) axial locking device, which is arranged in the region of the ring element 51 certain functional or grip positions can be displayed or fixed be what further improves the handling of the fitting 10.

Another embodiment of the fitting 10 can provide that the bolt 70 and / or the locking plate 80, 82 adjustable in height and / or pressure are trained. This can be achieved, for example, by using the Bolt 70 by means of a screw thread relative to driver element 62 designed to be screwed in or unscrewed. An additional spring in or on the bolt 70 can have a permanent pressure function. The same applies to the locking plate 80/82, which are adjustable via the rear-arranged cams 87 can be. Other configurations are also conceivable. Important is, that by the adjustability an adjustment of the relative distance between the locking bolt 70 and the engaging elements 85, 86 of the locking plate 80 or 82 is made possible so that the bolt 70 is always positive and non-positive in the locking part 80 engages.

It can be seen that an actuating handle 10 for opening to the outside Windows or doors a stop body 12 on a suitable wing profile is attachable, and also has a handle 40 with a handle neck 44 is axially fixed / rotatable on the stop body 12 and in it Inside via a power transmission unit 50, 60, 62 in functional connection stands with a linear slide-guided locking element 70 which is laterally in the Stop body 12 is guided, a substantially L-shaped or T-shaped Cross section and by operating the handle 40 with one on the window or Door frame arranged locking plate 82 are engaged can. The plate 82 has a face corresponding to the bolt shape undercut longitudinal recess 84 so that the bolt 70 in the closed position engages behind the associated locking part 80 at least in sections. The latter is additionally anchored in the frame with cams 87. This is preferred Locking element 70 attached to a driver element 62 that together with a pinion 50 attached to the handle 40 and one in the driver element 62 integrated rack 60 part of the power transmission unit is.
