Description

The The invention relates to a condition monitoring device for handle fittings for windows or Doors with a rotatable handle, wherein the condition monitoring device a with movements of the handle itself with this mitbewegendes, sensible or switching element and a corresponding sensor or having a corresponding switching element. It also concerns a handle fitting and a window or door.

Electrical condition monitoring devices for handles of windows or doors are known from the prior art, such as from DE 89 07 452 , In this document, it is proposed to assign the handle of the fitting a rotary contact switch having a rotary body with a permanent magnet, which is moved past a switching contact or sensor element.

This idea of the rotating switching element was used to monitor the condition in the DE 296 03 917 , This document proposes assigning the Einsteckverriegelungsteil or the pusher pin of the handle of a fitting detectable by a sensor element, which also performs a rotating movement, but with an even smaller radius than the initially mentioned prior art.

In front In this background, it is the object of the invention to provide a condition monitoring device for handle fittings for windows or doors to create, with simple means a significant increase in the reliability and switching accuracy of the monitoring function is reached.

The Invention solves this object by the subject matter of claim 1.

advantageous Embodiments are to be taken from the subclaims.

The The invention provides a condition monitoring device for handle fittings for windows or Doors with a rotatable handle of the generic to the device - a gear - for implementation the rotational movement of the handle in a linear - or largely linear - movement having the sensible or switching element.

Of the Concept of the sensible element is not closely related hereafter believe it. Rather, it comprises both non-contact sensitive elements like magnets, in particular permanent magnets or metallic, for example Teeth. About that It also includes switching elements, e.g. Cam or the like., The be moved past micro-switches, which actuated by the cams or are switchable.

Preferably Furthermore, the trajectory of the sensible element is exactly linear. But it can also describe a light bow, for example. its radius is significantly larger as the radius of a disk to be explained in more detail below about the pusher pin (Infra).

Of the Subject of claim 1 leads with the simplest structural means to a significantly increased switching accuracy, as it is by using a linearly moving switching element possible is, the contacts or sensor elements spatially further from each other spaced as on a rotating element whose diameter due to the cramped spatial conditions can only be selected relatively small on the handle fitting. From this increased Schaltgenauigkeit results in the desired significant increase in Switching accuracy.

There the sensible elements and also the sensor elements spaced to the trigger pin can be arranged can the monitoring device for example, in an oblong, narrow housing be accommodated in the look of modern windows or Fits doors perfectly, because it dispenses with a wide radial structure around the pusher pin. Just with narrow profiles, this results in an aesthetic advantage over the visually rather less appealing solutions of the prior art.

Thus, the prior art of DE 89 07452 after the realization of the invention has the disadvantage that the cooperating with a reed contact permanent magnet is in close proximity to the center of the rotary body and travels between its switching positions only a relatively small way on a circular segment. This creates circuit inaccuracies. In addition, the known switching device has the disadvantage that it builds up relatively high directly below the fitting to be monitored, resulting in a large amount of space.

Similar disadvantages DE 296 03 917 with himself. Here, the sensor element also performs a rotating movement, but with an even smaller radius, which in turn can lead to circuit inaccuracies. A disadvantage of this solution is that to realize the monitoring function, first a special handle fitting part (square push-button) is exchanged on the existing handle. This means that this part can not be used during a retrofit. In addition, it is not possible for every handle fitting to realize the proposed replacement at all. In addition, steel pusher pens are mostly used on the market, where is adversely affected by the action of the magnet as well as the switching action.

In contrast realized the invention a condition monitoring device for windows and doors with a high switching accuracy and a small size, the it also allows to dispense with the use of a special handle part. The Condition monitoring device according to the invention is suitable for original equipment of windows as well as for retrofitting existing constructions.

By the conversion of the direction of movement will make it possible the switching unit consisting of a permanent magnet and a reed contact, from the direct area the axis of the handle fitting away. This can be a very low height be realized. About that In addition, the switching accuracy is increased. By a relatively long Linear way can also realize multiple switching contact, by e.g. to be able to scan the positions "locked", "tilted" and "rotated" in a turn-tilt window.

By the novelty invention can during a retrofit the existing handle (handle fitting) without any change to be used again. This will reduce the costs and assembly times reduced.

The rotating movement of a pivot bearing housing can in several ways and Ways to be transformed into a linear motion. At a special preferred embodiment a flexible plastic band is placed in a guide of a housing.

alternative It is also conceivable to equip a pivot bearing with a toothing, whereby a rack is driven. Here are also translations be installed to increase the path of movement.

One particular advantage is the retrofittable housing, the designed for mounting between handle and window profile. It is preferably for receiving the electrical and mechanical Components of the state monitoring device designed and has a base plate and a one or more parts Cover on.

Prefers is to the base plate a cylindrical receiving collar for receiving formed a disc, which passes through the pusher pin form-fitting, so that the disc rotates with the handle pin of the handle. It makes sense, if in the base plate a guide is formed, in which a tape is inserted, which is displaceable in the guide. The guide has a circular arc surrounding the first section which merges tangentially into a second linear section. The band is designed flexibly and lies on its narrow side in the lead. On tape are e.g.

magnets formed, which in turn e.g. be moved past reed contacts. This solution is economical and still very functional.

The Invention also provides a handle fitting with a monitoring device according to one of the claims directed to this and also a window or a door with such a handle fitting. Both the handle fitting with the monitoring device as well as the monitoring device in themselves are for to be marketable and can as a unit or else separately e.g. also for retrofitting existing handles or existing windows or doors Tobe offered.

advantageous Embodiments will be described below with reference to an embodiment with reference to the drawing closer described. It shows:

1 an explosive view of a first condition monitoring device according to the invention.

2 a side view of the condition monitoring device 1 ,

3 a sectional view of the condition monitoring device 1 and 2 ;

4 a schematic plan view of the inner region of the condition monitoring device 1 to 3 in a first switching state;

5 the arrangement 4 in a second switching state; and

6 an exploded view of elements of another condition monitoring device.

1 shows a handle fitting 1 with a condition monitoring device according to the invention 6 is integrated. Concerning. the means and components for the realization of the mechanical handle function for opening and closing the window or the door can be largely or completely resorted to per se known components.

So shows 1 a handle fitting 1 that a handle 2 in which a pusher pin 3 is used. Such pushers 3 are often in the handle 2 pressed so that they can not be replaced easily in the rule. The present invention therefore dispenses with this measure of the prior art and solves the problem of detecting the movement of the handle in a completely different, more advantageous manner.

Although the condition monitoring device according to the invention is also known 6 designed to rotate the handle 2 capture. However, it does not arrange the sensible or switching element on the rotating handle 2 but translates the rotational movement of the handle 2 initially via a gearbox 23 in a linear motion, being the switching or sensing element on the linearly moving component of the transmission 23 arranges. In this way, it is possible to further space the sensor elements for detecting the movement of the sensible element, namely on a straight line, rather than on a circle, which increases the monitoring accuracy.

The mechanical transmission 23 can be realized in many different ways.

For example, the pusher pin 3 take a gear, which acts on a linearly displaceable rack. This solution works well (not shown here).

But even cheaper is the solution shown here, in which the pusher pin 3 turn a wheel or a disc 15 interspersed, which he turns with his turns.

The handle is rotatable on a rotary bearing housing 4 arranged, which rotatable with the handle pusher pin 3 interspersed and in turn on a housing or its cover 11 the monitoring device can be mounted (eg screwed on), which in the area 7 for the attachment of the handle fitting a hole 8th for the pusher pin 3 and drilling 9 for the fixing screws 5 having. In this area, the housing can be reduced to a very low overall height a, which is preferably only three to ten and particularly preferably five millimeters.

Outside the handle fitting area 7 points the cover 11 page sections 10 on, which have a slightly higher height than the handle fitting area, so that in the interior of the cover 11 or the housing from cover 11 and base plate 13 the mechanical transmission 23 and electrical components can be accommodated. These include, for example, a circuit board 12 , Battery 22 , a transmitter (not shown here in detail) and reed contacts 20 . 21 ( 4 and 5 ). In or under the cover or the housing 11 So are at least one or more boards 12 and the base plate 13 arranged.

The cover 11 can according to a preferred embodiment ( 6 ) Also formed in two parts and be centrally divisible and also the rotary bearing housing 4 cover with. The rotary bearing housing 4 in this case is directly on the base plate 13 assembled. Here, the base plate sidewalls 24 have and lateral projections or webs 25 , by guide elements (not visible here) inside the two cover parts of the cover 11 be under attack, so that the cover parts are pushed onto the base plate. This variant is on the one hand handy to handle and is characterized by a particularly attractive appearance. The rotary bearing housing 4 is preferably completely covered.

The cover 11 can also on the base plate 13 be aufklippsbar. This variant is particularly advantageous when a two-part cover is used, which is not held by the handle fitting.

The base plate 13 has a round or cylindrical receptacle 14 for receiving a disc 15 on. This disc 15 in turn has one to the geometry of the trigger pin 3 corresponding opening 17 on which the pusher pin 3 interspersed, so that the disc 15 during rotations of the trigger pin 3 with this rotates, so that the disc 15 upon actuation of the handle 2 performs a rotating movement.

In the base plate 13 is a guide 18 trained in a band 16 is inserted, which is displaceable in the leadership. The guide initially consists of the recording 14 and concentrically surrounds the disk 15 until it transitions tangentially into a linear section. The disc 15 can on at least one side a leading cylindrical approach 29 have (not visible at the bottom), in a pivot bearing receptacle 28 engages the center in the in the guide 14 is arranged.

The ribbon 16 lies on its narrow side in the lead 18 , It is flexibly designed and with its one end on the circumference of the disc 15 set so that it turns in the handle or the trigger pin 3 on the outer circumference of the disc in the receptacle 14 can create or solve this again. The linear section in the channel 18 is moved along. This is the rotational movement of the handle or the handle pin 3 in a linear motion of the disc 15 remote area of the band 16 implemented: By operating the handle fitting 1 So is the rotational movement of the handle 2 over the glass 15 on the tape 16 transferred and converted into a linear motion.

At the area of the strip which moves away from the disk in a linearly moving manner 16 are on this two switching or detectable elements, here two permanent magnets 19 placed. Alternatively, you can work with a different number of magnets, but at least one magnet. The movement of these magnets is from one or more reed contacts 20 . 21 ( 4 ) Sensible, in which the permanent magnets 19 during rotations of the handle 2 move past.

Preferably, these reed contacts 20 . 21 together with an evaluation circuit on the board 12 arranged, which also has holes and breakthroughs 30 . 31 especially for the pusher pin 3 , the screws 5 and the battery 22 having

The Circuit may also include a transmitting unit, the switching states preferably wireless, e.g. by radio or infrared - to an external receiving unit (Building management, Alarm system etc.) can send.

4 and 5 show a schematic view of the base plate 13 and the board 12 , On the outer circumference of the disc 15 in the base plate 13 is well used, the guide for the on the outer circumference of the disc 15 attached band 16 to recognize. The ribbon 16 performs with rotations of the handle and the pusher pin on the outer circumference of the disc 15 a rotating movement in the guide section (recording) 14 , causing the tape 16 tangential in the lead 18 is moved.

The elastic band 16 has here at its one end a coupling element to the disc 15 on - eg a thickening 26 in a picture 27 on the outer circumference of the disc engages - and at its other end at least one or more of the permanent magnets 19 ,

Also in 4 shown here are the two reed contacts 20 and 21 in a preferred embodiment above the base plate 13 on the board 12 are arranged. The permanent magnet 19 is at the height of the reed contact 20 , which here corresponds to the "closed position of the handle.

In 5 is the disc 15 twisted by 180 °, leaving the tape 16 undergoes a change in length or has performed a linear movement. In this position is the permanent magnet 19 in the area of the reed contact 21 , Here, the position "open" can now be detected for a window or door element.

Instead of an elastic plastic band 16 , which converts the rotating movement into a linear movement, other transmission variants can also be used. For example, the disc can 15 have an external toothing and instead of the band 16 drive a rack to which then the permanent magnets are attached The individual components mentioned can be made for example of metal as well as plastic. To increase the switching accuracy of the permanent magnets, it makes sense, especially the band 16 and the disc 15 made of plastic.

The condition monitoring device according to the invention can be used particularly advantageously in conjunction with window handles for turn-tilt windows. Usually, these turn-tilt window on three positions, which are set by a two times 90 ° rotary motion. These are the closed position (0 °), the rotary position (90 °) and the tilt position (180 °). The permanent magnet 19 moves the positions "Reed contact 20 " , "No reed contact", "reed contact 21 " from that correspond to the three possible positions of the turn-tilt window.

It is also conceivable to detect even more positions, eg for a night ventilation position. It is also possible, by a suitable translation, the rotating movement in an even longer or even shorter linear motion than in 4 and 5 represented to transform.

shown is a band that is shifted in one direction. In particular Cases can an insert of two bands (180 ° offset arranged on the disc), each in opposite directions be moved, be beneficial. This allows the sensible or switching Elements can be arranged even further apart from each other.

Also can additional magnets or reed contacts in the housing of the condition monitoring device be integrated. Which also includes e.g. a reed contact, which is arranged with a on the frame Permanent magnet together gives off an impulse whereby the closed or open position of the window sash is detected.
