Description

The present invention relates to a motor-driven roofing according to the preamble of claim 1. A generic canopy is from the DE 20 2013 009 331 U1 known.

Such roofs, which usually consist of several, self-moving elements, are used outdoors, for example, to protect in the extended state ("roofing closed") swimming pool or outdoor seating from adverse weather conditions. However, if you want to use so protected swimming pools or outdoor seats, so the elements can be so interlocked, d. h., push that the pool or the outdoor area is at least for the most part not covered ("roofing open").

When operating such a canopy, ie, when opening and closing, there is a risk, however, that the individual elements tilt together and / or do not move along a common line (eg, break sideways, viewed from above) and thus actuate the roofing difficult or even prevent. Therefore, such a roofing is conventionally performed by means of external guide rails, so that such disadvantages can no longer occur. However, such guide rails also have serious disadvantages: they are trip hazards in which z. B. with shoes, especially those with small heels, or even with the toes when walking barefoot, which is known to fall with z. T. serious consequences. To avert this danger, one could of course the free spaces within the guide rails when not in use with filling material such. B. Fill bars or sand and thus defuse these tripping hazards. However, you must then remove the filler before each use of the roof, which is at least annoying.

The object of the present invention is to provide a motor-actuated canopy which has as few disadvantages as possible and in particular avoids the aforementioned disadvantages.

The above DE 20 2013 009 331 U1 already discloses a solution without guide rails. With the present invention, a further solution is to be provided.

This object is achieved in a generic roofing with the characterizing features of claim 1. Advantageous embodiments and further developments are characterized in the subclaims.

The invention will be explained in more detail with reference to a drawing. Showing:

FIG. 1 shows, as already stated, an embodiment of a motor-actuated canopy according to the invention in side view. The canopy is arranged in this embodiment on a substrate, which is symbolically indicated by the reference numeral "U". This underground U may be z. B. a swimming pool or a patio (for clarity and not part of the invention: not shown or indicated). The canopy is in fully extended state shown. It comprises several elements, namely a first element E1, a last element EL and further elements E2 and E3 arranged between these elements E1, EL. The first element E1 is arranged stationary on the substrate U, but can be moved in a particular embodiment, as will be shown. The last element EL and the further elements E2, E3 are pressed against the first element E1 along a straight line (in Fig. 2 shown with two-sided arrows and denoted by the reference numeral "L") on the first element E1 out (and back again) freely movable, z. B. at least for the most part in the first element E1 into it. This condition is in Fig. 2 shown, which also shows the roof of the invention in side view.

The method of the further elements E2, E3 and the last element EL, ie, the opening and closing of the roof according to the invention, by means of electric motors. For this purpose, the last element EL has at least two motor units M1, M2, each of which contains at least one of the electric motors. Each of the motor units M1, M2 is arranged on a separate mounting area MB1, MB2 of the last element EL. The mounting areas MB1, MB2 are arranged on the last element EL side by side opposite each other. The electric motors of the motor units M1, M2 cause in operation by means of in Fig. 4 shown wheel units R1, R2 a method of the last element EL and, as a result, a method of all other elements E2, E3 on the first element E1 to (and into this, at least for the most part, a method in this direction is in view of a swimming pool, possibly located below the canopy, hereinafter referred to as "opening") and also away from the first element E1 away (movement of the elements in the opposite direction, which is hereinafter also referred to as "closing"). The mounting areas MB1, MB2 together with associated motor units M1, M2 are in Fig. 4 something shown in detail, including the above-mentioned wheel units R1, R2.

The process of the last element EL and the further elements E2, E3 takes place from an initial position P1 of the last element EL to an end position P2 thereof or back again. The two positions P1, P2 are from the Fig. 1 and 2 seen. It is advantageous to design the last element EL so that it can be fixed in place in the initial position P1 and / or in the end position P2, for example, with respect to the ground U.

As in the Fig. 1 and 3 1, the roof according to the invention also has a control unit CTRL, which serves to control the two motor units M1, M2 and thus a process of the last element EL and the further elements E2, E3 such that in operation in the one process direction the last element EL from the initial position P1 to the end position P2 is movable and vice versa in the opposite direction accordingly. Naturally, each of these two positions P1, P2 can serve as starting position for the method.

According to the invention, the control device CTRL is furthermore designed such that it can influence the rotational speeds u1, u2 of the two motor units M1, M2 independently of one another. It is also designed so that during a procedure, they regularly detect the distances s1, s2 of the two wheel units R1, R2 covered by the respective starting position P1 or P2 at the same time, compare them and detect differences occurring between two at the same time Routes s1, s2 the motor units M1, M2 can influence in terms of speed to the effect that in subsequent detection of each simultaneously covered distances s1, s2 occurring differences are minimized, at least in total as possible. At the same time an "overshoot" of the differences is accepted, ie an occasional occurrence of negative differences and positive differences between the distances s1, on the one hand, and s2, on the other hand. This makes it possible to achieve that the last element EL (and also the further elements E2, E3) in the end ultimately moves very precisely along the straight line L. The lower these occurring differences whose cause, for example, in technology tolerances of the motor units M1, M2 and / or external influences such. B. Crosswind during the process and / or slightly rough to be driven underground U may be, the more accurate the process along the imaginary line L.

Trajectories s1, s2 traveled at different times are exemplary in the diagram of FIG Fig. 5 shown. In this case, the designations t1, t2, t3 and t4 represent the different points in time at which the hitherto traveled distances (respectively denoted by s1 and s2) have been detected. The differences between the illustrated lengths of the distances s1, s2 per time point t1, t2, t3 and t4 are the differences between the distance traveled s1, s2.

The Fig. 4 shows, viewed from the front, for reasons of clarity, only a part of the roof according to the invention, namely the last element EL together with the mounting areas MB1, MB2, the motor units M1, M2 and the wheel units R1, R2, arranged on the already mentioned substrate U. Furthermore is still, symbolically, the control unit CTRL shown.

To the roof of the invention, for example, against coarser weather conditions such. B. to protect sudden storm squalls, it is advantageous if the last element EL is fixed in place at its initial position P1 and / or end position P2.

In an advantageous embodiment, the control unit CTRL contains a memory area MEM. The values of, for example, the distances s1, s2 detected at different points in time during a first-time method operation, the associated speeds u1, u2 of the motor units M1, M2 and the wheel circumferences of the wheel units R1, R2 can be stored and provided again for further uses, for example later occurring process operations and for so-called. Corrections. Correction rides are those rides that are performed after the occurrence of large lateral deviations from the imaginary line L. Such deviations can be caused for example by crosswinds. For this purpose, the control unit CTRL is advantageously designed so that it continuously detects the difference between the detected distances s1, s2 and initiates such correction travel when a given limit value is exceeded with speeds u1, u2 of the motor units M1, M2, those of those speeds u1, u2 are different, in which the correction trip, so the previous method of the elements, has been triggered. These speeds u, u2, which are different from the previous method, are determined by the control unit CTRL from the differences between the detected distances s1, s2 of the previous method, the detected distances s1, s2 themselves and from the corresponding values of the original, first-time method stored in the memory area MEM of the elements can be determined.

It is also advantageous if each of the motor units M1, M2 has a rotary encoder Imp1 or Imp2. The control unit CTRL is set up in such a way that it can continuously determine, per wheel unit R1, R2, the respective distance s1 or s2 traveled since the start of the process of the elements from the number of pulses respectively emitted and the tread circumference of the respective wheel unit R1, R2. It is also advantageous if each wheel unit R1, R2 has more than one rotary encoder, preferably 2, 5 or 10 to 20. Thus, the resolution is increased, ie, the way that the the last element EL between two consecutive pulses, becomes even shorter; it can thus be detected even finer than in the presence of only a single encoder. For example, given the use of two encoders per motor unit M1, M2, given rotational speeds of motor and wheel units M1, M2; R1, R2 and given tread circumferences of the wheel units R1, R2 give a resolution of 2.4 mm, while using 16 encoders results in a resolution of 0.000044 mm under otherwise unchanged conditions. In turn, at a higher resolution, the control unit CTRL can perform necessary corrections due to smaller differences between the distances s1, s2 during the movement of the elements even more sensitively.

Furthermore, it is advantageous if the last element EL preferably in the vicinity of each motor unit M1, M2 has a fastening element B1, B2 for engaging in a respective stationary receiving element A1, A2, when the last element EL has reached its end position P2. This is in Fig. 4 symbolically represented. It is favorable to design the fastening elements B1, B2 and the receiving elements A1, A2 as interlocking closing tongues and locking locks in the manner of safety belts and locks in motor vehicles, which are preferably electromagnetically lockable and / or detachable.

The 6 and 7 show a further advantageous detail of the present invention. In this case, an end mark EM1, EM2 is provided in the region of the end position P2 of the last element EL per motor unit M1, M2, preferably on or in the ground U. The last element EL has two mutually adjacent proximity sensors SE11, SE12 and SE21 per motor unit M1, M2 , SE22, which are arranged in pairs transversely to the imaginary line L. By means of these proximity sensors SE11, SE12 and SE21, SE22, upon reaching the end position P2, signals can be output to the control unit CTRL which indicate whether the end position P2 has been reached exactly or whether in moving the elements along the imaginary line L also an (undesired) lateral displacement has taken place. In Fig. 6 the case is shown in which the end position P2 has been reached exactly. In this case, the proximity sensors SE12 and SE21 send a signal to the control unit CTRL informing it that the end position P2 has been exactly reached, whereupon it terminates the process of the elements.

However, during the process of the elements, there has also been a lateral displacement, ie a lateral deviation from the imaginary line L (shown in FIG Fig. 7 ), then neither the proximity sensor SE12 nor the proximity sensor SE 21 emit the aforementioned signal. Rather, the one of the proximity sensors SE11, SE22 outputs a signal to the control unit CTRL which is closest to one of the end markers EM1, EM2. At the in Fig. 7 this situation is that of the proximity sensor SE11. The control unit CTRL then decides, depending on the originally made programming state, whether it immediately initiates a correction run according to the corrective travel already described above or whether in the next method of the elements, ie, in a process "back" in the direction of the initial position P1, the occurred lateral deviation (which results from the differences of the distances s1, s2 that have arisen) by suitably adapting the speeds u1, u2 of the motor units M1, M2.

In a further advantageous embodiment of the motor-operated roofing, the control unit CTRL is designed such that the roofing in the open state, ie in the in Fig. 2 in the same way as described above, in a direction opposite to the direction in which the last element EL is moved on its way from the initial position P1 to the end position P2. The canopy can be as a whole in bring a parking position in which a recessed on the underground U swimming pool in use case upwards completely free of the roof.

Overall, the canopy according to the invention has the advantage that the processes of the method of the elements can proceed completely automatically. The initiation of a procedure can be done in many ways such. Example, by means of a simple electrical button or wirelessly via a network connection (eg., WLAN), a Bluetooth connection or a wireless telephone connection (mobile phone).
