Description

The invention relates to a slide rail with a guide groove and System side for one with a slide rail system and a drive equipped door closing device for a door, being in the guide groove a slide or roller that is operatively connected to the drive or other equivalent is axially displaceably mounted, and the door area at least one, the danger zone of the door movement area the door scanning and effective with the door locking device connected, sensor is assigned.

Generic slide rails are used in doors - in particular Swing doors - used and mounted in the upper door area, whereby the Slider sliding in the guide groove usually via a lever or a lever linkage mechanically coupled to the door operator stands. According to DE 44 15 401 C1, it is common for such door drives with arranged on the door leaf in the area of the lintel Danger area of the movement area of the door scanning sensor or sensors to connect the signals to the door operator via the respective Send connection that will trigger a door stop as soon as someone enters the danger zone.

A disadvantage of known arrangements is that the connecting lines of the Sensors must be laid more or less widely, which means they are subject to willful or accidental damage.

Another disadvantage is that considerable assembly effort is required, because the attachment of the door drives with the slide rails on the one hand, the Sensors and the associated wiring to the other relatively time consuming is because sensors and slide rails are practically in the same door area must be installed. For example, channels for the Assembly of the cables to be drawn in are provided to the Sensor or the

Sensors connecting cables to the door operator from damage Protect. Damage to the connection cable can pose significant risks because the sliding or swiveling range of the door is then not or can only be monitored inadequately and so it is with power-driven Door drives during the automatic opening and / or closing process easy to injure people in the danger zone can come.

The individual sensors have an extremely disruptive effect on the harmonic Picture of a door, since it is often in apparently unfavorable places are arranged. Just as disruptive and costly are those for assembly necessary mounting plates.

It is also particularly disadvantageous that the spare parts inventory is complex because the most diverse combinations of door operator / sensor arrangements are to be stored, which leads to the binding of considerable capital, what ultimately the products become more expensive.

The object of the present invention is the previous technical Disadvantages, especially to overcome the difficult assembly and above all to avoid the previously necessary commitment of capital and at the same time to harmonize the external appearance of a door.

The invention is solved according to the characterizing part of patent claim 1. The slide rail has one to which the slide piece receives Guide groove adjacent space for receiving at least one of the Monitoring of the danger zone of the door serving sensor, the space being arranged below, in front of or behind the guide groove can be.

This will keep the variety of different combinations of spare parts door drive / sensor systems considerably reduced. That too is Installation significantly easier and therefore more economical because there are no additional ones Measures - such as additional cable ducts in the door leaves or the sheathing of long cable connections from the sensor for door drive - must be planned in.

At the same time, the slide rail according to the invention is visually appealing into the entirety of the door, with the wiring also being subtle keeps in the background and so does the increasing vandalism today rather escapes. This ensures the safe operation of the door and there are injuries due to incorrect control of the door drives avoided.

It is particularly advantageous when designing a slide rail according to the Invention when the space in the longitudinal direction from the stop side forming wall, and one. opposite the stop side, the wall forming the front, limited on each side of the slide rail the side facing away from the underside of the guide groove forms an opening which is permeable to the radiation from the sensor or sensors, which is equipped with an appropriate cover.

In this way, inexpensive standard sensors can be used since these are to be scanned within the room according to the Solid angle can be attached. Of great advantage it is also that the slide rail according to the invention as a continuous casting profile As a semi-finished product that can be used universally for all doors, storage is particularly important relieved. Depending on the door width, it is only necessary to cut it to length and the inclusion of the sensors within the room, so that no stockpiling of combinations of different door operator / sensor systems is more necessary.

It is also advantageous if the space is covered by a connectable to the slide rail, the radiation of the sensor or Sensors permeable cover is complete, the cover non-positive and / or positive in the rear and front walls the slide rail can be inserted, clamped or inserted can be.

This makes manipulation of sensors particularly easy prevented. If the insertable version is selected for the cover, So the space for sensors is only by dismantling the slide rail accessible so that the room is no longer accessible to unauthorized persons is.

Preferably, they have the stop side and the front side Wall recordings and the cover corresponding counterparts on. This configuration favors inexpensive manufacture both the cover and the slide rail profile.

With heavy or extra wide doors it has proven to be particularly useful proven the area of the guide groove of the invention Slide rail at least one structurally mechanically active cavity assigned. This will twist the slide after Avoided invention.

For fastening the slide rail to the door leaf or to the lintel it is advantageous if the openings intended for fastening the slide rail in the lower area of the stop side, accessible from the front are arranged. This makes assembly even easier since no drilling templates for making the mounting holes in the Door leaf and / or the lintel are more necessary and no additional Mounting plates are required.

If the slide rail according to the invention one or both ends of the slide rail positively and / or non-positively or this encompassing cover cap is assigned, then the space is also ahead of others Encapsulating environmental influences.

The assembly becomes even more efficient if each cover cap is used Attachment of the slide rail is used, and at least one each Opening and / or if at least one of the cover caps for implementation has predefined, openable outbreaks of connecting lines. With doors of normal door width, this means that the stop side can be opened penetrating holes are omitted and the laying the cable connections are made in the immediate vicinity of the door operator.

It is preferable if the slide rail extends approximately across the width extends of the door leaf, whereby at the same time that which can be scanned by the sensors entire danger area on this side is detectable.

By using a slide rail according to the invention without associated Door operator, but equipped with at least one sensor on which Door side facing away from the door drive for the purpose of monitoring the danger area there, becomes a standardized, easily adaptable to all requirements, easy to assemble and a minimum of inventory Required, reliable, driven by automatic door drives Door or doors provided.

In particular, the use of a slide rail according to the invention offers even without an associated door operator, but with at least one sensor equipped, attached on the side facing away from the door drive, the Advantage, also the monitoring of the danger zone there without much effort allow, the appearance is appealing is and no other parts are necessary for this.

A semi-finished profile for a slide rail according to the invention is special practical if - viewed in cross-section of the profile - the stop side forming a U-shaped, axially extending groove is, with one of the two legs of the U-shaped groove one also has axially extending elevation.

Such a semi-finished profile can also be used on the front Wall of an at least three-leg, axially extending groove be assigned, being between the wall of the front and the last leg an axially extending gap remains.

An invisible fastening can be achieved with the object according to the invention the slide rail with attached sensor without use a mounting plate. This has one correspondingly great advantage over the prior art and is also characterized by an aesthetic type of attachment.

In an embodiment of the inventive idea, however, can also both the slide rail and the area for receiving a sensor can be integrated into a profile, which is a cross profile on a door forms the upper end. Both folded and not folded profiles are used. With such a profile An attachment of the slide rail with sensor may not be necessary as it is a one-piece part. The viewer would not notice that at the same time the slide rail is formed, which in such Trap can be much narrower than usual. It is also possible, the cross profile on both sides with a holder for sensors and to form as a slide rail, with only one side of the slide rail guide would be used.

Such a semi-finished product profile offers mainly for warehousing and Installation has the advantage of not stocking any further prefabricated slide rails and so by simply cutting to length local conditions to be able to take into account in a particularly simple manner.

A slide rail specially protected against unauthorized interference According to the invention, if the cover is in the form of a semi-finished profile, in the - viewed in cross section - the right and / or the left edge of the cover forms an L-shaped termination. hereby becomes a stable connection between the slide rail profile and the Coverage reached.

Furthermore, the present invention is based on one in the figures more or less schematically illustrated embodiment described.

Door leaf 1 is hinged about bands 3, and for actuation there is a pusher 6 with it not shown lock within the frame profile. The top end the frame forms a profile 21 on which a slide rail 10 is attached according to the invention. The slide rail 10 with integrated Sensor is connected via a cable transition 4 to the wall and to it Cables connected. Within the slide 10 is a Slider 20, which is also a role or any other type of sliding Can represent part, guided by a lever 2. The other free end of the lever 2 is on a door closer or on one electromechanical or electrohydraulic door operator connected. When actuated based on the sensor signal of the drive, the door leaf 1 opens automatically and thus gives the person arriving Clear the way.

The slide rail 10 is fastened to a door leaf 1, as indicated in FIG. 2 is.

From Fig. 3 it can be seen that the pivotally connected to a lever 2 Slider 20 in a guide groove encompassing the slider 20 12 is guided axially. The lever 2 is on the other hand with a - since not belonging to the invention - not shown door drive and this again connected to sensors.

Cavities 13, 14 are assigned to the area of the guide groove 12 on both sides, the sides of the slide 10 a structural mechanical reinforcement in the form of reinforcing ribs 131 and 141 and additionally result in a material saving.

A wall 11 * of the stop side 11 with which the slide rail 10 on the door leaf rests, is extended downwards and of an L-shaped Reinforcement edge 17 completed. The reinforcing edge 17 is with one U-shaped groove extending axially along the slide rail 10 171 equipped, the elevation 172 at least on one leg having.

For fastening the slide rail 10 to the door leaf 1 or the lintel are 11 holes in the lower part of the wall 11 * of the stop side 111 inserted through the fasteners, e.g. Wood or metal screws, Grab tie and the like.

The wall 16 forming the front is also extended downwards, however, only shows about half the length of the back stop side 11 forming wall 11 *. At the guide groove 12 facing away End of the wall 16 * of the front side 16 has an axially along the slide rail 10 extending three-legged groove 161, at the gap 162 also extending axially of the slide rail 10 remains.

The wall 16 * of the front side 16 and the wall 11 * of the stop side 11 thus form a on the side 15 facing away from the guide groove 12 Room 30 in which one or more sensors are housed. Both Sensors are commercially available sensors opto-electronic and / or radio-electronic in nature in the usual way Screws, rivets, gluing or clamping within the space 30 attached are.

Between the walls 11 * and 17 * remains a free opening 41, which by a cover 40 is closed. The cover 40 has on both sides an L-shaped termination 42, 43.

The material of the cover 40 must take into account that this the highest possible transmission of the optoelectronic and / or radioelectric Radiation from the sensors.

The cover 40 can easily be mounted on the door after the slide rail with the door open with the L-shaped ends 42 and 43 in the axially extending grooves 161 and 171 inserted and fastened End faces of the slide rail covered with a cover cap 18 and 19 become.

The cover caps 18 and 19 can form and / or in the slide rail 10 engage non-positively, or - as shown in Fig 2 - this grip positively and / or non-positively. For the implementation of the Connection lines 5 relating to sensors have at least one of the Cover caps 18 or / and 19 a predefined, openable opening 182 on. This can e.g. for cover caps made from injection molding 18, 19 through predetermined breaking points or at die-cast Cover caps are made through openings closed with plugs.

As indicated in Fig. 2, the cover caps 18, 19 have holes 181, 191, through which the two ends of each with a cover cap Slide rail 10 attached to the door leaf 1 in a conventional manner is. The holes 181, 191 are not shown, in the hole each plug used is blinded.

4 shows a profile 21 of a door leaf 1 shown, the glass filling 7 is held by a glass strip 8. The profile 21 has a repellent leg 26 in which a seal 27 is located. The seal 27 lies against the profile of one Frame 22 on. 4 shows the door in the closed position Status. The chosen representation should make it clear how the connection of the slide rail 10 to the profile 21 in an invisible manner and Way via fastening screws 9, which are within the space 30th the stop side 11 are done. Will the room 30 through the cover 40 closed, fastening the slide rail 10 is not more visible.

In the embodiment of the idea according to the invention can start 4, in which a separate profile is used for the slide rail 10 in addition to the profile 21 of the door leaf 1, such a profile is used come, which at the same time the slide rail 10 with attached Room 28 integrated for a corresponding sensor system. The Attachment of the glass filling 7 is done in a known manner and is held within the frame profile via a glass bar 8. This including both frame and slide rail with subsequent sensor Profile is designated 23. The profile has the following essentials Features on, namely: a guide groove 12 acts as Slide rail for a slide 20, a space 28 for receiving a Sensor technology with attached outer cover 20, and at least two chambers 24 and 25. The illustration in FIG. 5 shows a such profile 23, which is used for unfolded doors. However, it is also conceivable to have such a profile with a repellent Equip thighs so that it can also be used to manufacture rebated doors to be able to. This would represent a profile, which is in one piece would be, but which is shown in two parts in the figure.

By using a one-piece profile, the entire structure the slide rail function become smaller, which also the optical Appearance benefits. Such an execution would be the viewer do not attract attention and, moreover, an expensive assembly is unnecessary do.
