Description

The invention relates to an installation device according to Preamble of claim 1.

Installation devices of this type are state of the art known and are for example for flushing urinal systems used. For this is behind a cover plate in the Wall opening housed a urinal control, for example using an infrared system after use of the urinal triggers an automatic flush without contact. The cover plate is detachably attached to the frame and secured. The cover plate is usually mounted by with its upper edge on a resilient element of the frame hung, pulled down and finally on hers bottom of an undercut at the bottom of the frame is hooked in. To secure the cover plate on the frame is a small one at the bottom of the cover plate Attached by a hole in the frame a thread attached to the frame is screwed in.

EP-0 779 397 A shows a generic installation device on, in which the locking device is a U-shaped Component that is stored in a frame and when mounting against compression springs in a locking element Cover plate snaps into place. To loosen the cover plate, the Component lifted with a two-pin tool and thus unlock the cover plate. With this device there is a risk that the cover plate in a vandal act pulled down and unhooked at the bottom becomes.

DE 40 05 753 discloses an installation device, at which the cover plate at its lower edge by a fastening screw is held. Here too is a wanton The cover plate can be removed without tools.

The control system housed in the wall opening must be regular being repaired. This requires the cover plate completely remove and after maintenance again to assemble. For systems with many urinals, one is such maintenance work is comparatively time-consuming since each Cover plate can be removed individually and reassembled got to. The screw provided for securing each Unscrewed once and then screwed back in become. This is the manual skill of the maintenance person Often overwhelmed and often such a screw goes lost and must be searched again or a spare part must be found be procured. Attaching a bigger and better accessible screw would largely address the problems mentioned to solve. Because of vandalism, however, is a big and easily accessible screw not advisable.

The invention has for its object an installation device of the kind mentioned to create the vandal proof is and still a simple and not very time-consuming Maintenance enables. The task is with a generic Device according to claim 1 solved.

In the installation device according to the invention as before, the plate first at the upper edge and then hung on the bottom of the frame. Here, the locking element in the holding element connected to the frame pivoted. With an Allen key then, for example, the locking element rotated 90 ° into the locked position. The locking device thus forms a quick release, which holds the plate in relation to the frame. The locking device thus only prevents that the plate is pulled down and at the bottom of the Frame can be suspended. Because the locking element is captively stored on the plate, this can be Maintenance work is not lost. The one for unlocking and locking necessary movement of the locking element is much easier and faster to execute than the previous screw movements. The inventive Locking device can be hidden behind at the bottom the plate and is arranged by a small The opening of the plate can be operated and at least just as vandal-proof as the device according to the named State of the art.

According to the invention, the locking device on the locking element and on the holding element one for each other, releasable engagement Serration on. These serrations are through when locking engaged in a rotary motion. This intervention prevents with great certainty a shift of the Plate down. It is also advantageous that such elements very inexpensive in a suitable plastic Injection molding processes can be produced. Know that Holding element according to a development of the invention front opening, that's how it is when mounting the plate Locking element through this opening in the holding element pivoted. This is the usual assembly process where the plate is first at the top and then attached to the frame at the bottom, still possible. The most common assembly steps so far can thus also in the device according to the invention to be kept.

Further advantageous features result from the dependent ones Claims, the description below and the drawing.

An embodiment of the invention is explained below with reference to the drawing. Show it:

FIG. 1 shows a schematic view of the installation device according to the invention, the cover plate being removed,

FIG. 2 shows a view according to FIG. 1, but with the cover plate fitted,

FIG. 3 shows a section through the locking device, the latter being in the unlocked state here,

FIG. 4 shows a section according to FIG. 3, but in the locked state,

Figure 5 is a view of the locking device seen in the direction of arrow V of Figure 3, with parts of the plate broken away for reasons of drawing, and

FIG. 6 is a view according to FIG. 5, the locking device according to FIG. 4 being in the locked state.

As shown in FIG. 1, there is a rectangular opening 5 a wall 6, a holding frame 4 used and with four Screws 26 attached. Behind wall 6 is one here Flushing device, not shown, for example a pressure flushing valve arranged with one arranged in the opening Control 8 is controlled. The controller can For example, have an infrared system 27, the automatic and contactless flushing of the not shown here Urinals enabled.

According to FIG. 2, the opening 5 is completely covered by a cover plate 1 covered, preferably made of plastic is produced and a transparent to infrared rays Has window 9. The cover plate 1 is detachable on the frame 4 and is attached to this frame 4 according to FIG. 1 placed by an upper edge 2 of the plate 1 in the direction the arrow 23 at the top of the frame 4 on resilient Elements 7 hung and then a lower one Edge 3 of plate 1 in the direction of arrow 24 at the bottom Edge of the frame 4 is hooked. The springy elements 7 push the cover plate 1 upwards and ensure so that the cover plate 1 with its lower edge 3 always is in engagement with the frame 4. To the according to Figure 2 to secure the cover plate 1 mounted on the frame 4 locking device 30 explained below according to Figures 3 to 6 provided that with the cover plate mounted 1 invisible behind the window 9 above the lower one Edge 3 is arranged.

The locking device 30 consists essentially of a holding element 16 attached to the frame 4 and one Locking element 10 in one with the cover plate 1 firmly connected bearing part 20 is rotatably mounted. To the Rotating the locking element 10 about the axis of rotation 31 this element 10 has an axial depression in a foot 13 15 through which a tool 32, for example an Allen key can be used. This deepening 15 is arranged above a passage 19 of the cover plate 1. This passage 19 is just wide enough that Tool 32 through this passage 19 into the recess 15 can be used. The bearing part 20 has a cylindrical Passage 21 in which the locking element 10 is rotatably mounted. The locking element 10 is inserted from above into the passage 21 and radially protruding parts 13a rotatably locked. So when inserting these parts 13a are deflectable inwards, is the Provide foot 13 with a slot 14 in its longitudinal direction.

Over the foot 13, the locking element 10 has a Head 11, which has opposite teeth 17. When the cover plate 1 is mounted, this head 11 engages in one Opening 18 of the holding member 16. In this opening 18, which is open to the right in FIG. 3 is corresponding a toothing 17 is also attached to the toothing 12. Is the head 11 in that shown in Figures 3 and 5 Position, the teeth 12 are out of engagement with the Teeth 17 of the holding element 16. Will the locking element 10 by 90 ° in the position shown in Figures 4 and 6 the opposite teeth are turned accordingly 12 pivoted about the axis 31 and come into engagement with the teeth 17. This pivoting movement is preferred completed with a stop, for example by a stop of the head 11 on the holding element 16. This Stop can be designed so that reaching the stop position is audible. It is also conceivable that in a noticeable rest process takes place at the end position. Such Locking means are known per se. The locking element 10 is thus in its axial direction in the holding element 16 set. As a result, the cover plate 1 not moved downward in the direction of arrow 33 (FIG. 4) and therefore cannot be dismantled. The edge 3 engages behind the frame in a manner not shown here 4, so that a horizontal removal of the edge 3 from Frame 4 is not possible. Since the cover plate 1 on Frame 4 is held by the edges 2 and 3, that is Locking element 10 substantially unloaded.

To release the lock, the locking element 10 in the opposite direction of the arrow 25 shown in FIG. 2 by 90 ° pivoted. The teeth 12 are no longer in Engagement with the teeth 17 and the cover plate 1 can against the retroactive force of the elements 7 shifted down and be posted. Locking and unlocking is done by a short movement of the tool 32. The locking device 30 thus forms one Quick release fastener that is easy and quick to use is still very vandal-proof and inexpensive to manufacture can be.
