Description

The present invention relates to a door, in particular garage door with a door leaf, which is followed at its lower edge by a terminal strip, with a door drive connected to a control and with a light change device connected to the control, which is arranged on the end strip.

The door leaf can be formed by a plurality of panels, a swinging wing, a rollable material or even a rigid, movable in one plane wings. A main application case are sectional doors of garages, in which the door leaf is formed of several panels, wherein the panels are hinged together via horizontal axes and can be transferred along a guide from a vertical closed position to a vertical deviating, in particular horizontal opening position. Furthermore, it may also be without restriction to a sliding gate, roller shutter or swing gate.

Specifically, the invention relates to a gate, which is also provided with a door drive, which is connected to a controller. By a suitable input device, such as a button, a radio remote control or even with a corresponding data connection to a mobile device, the opening and closing movement of the door can then be initiated.

When moving the door leaf through the door drive, it should be noted that dangers to a user can not be excluded. If the door leaf is not fully opened or during the closing movement, there is a risk of a collision if a person or a vehicle is being driven by the door the door opening to be closed happens. There is also a risk of pinching during a closing movement, even if gates are usually equipped with a safety shut-off.

Finally, depending on the design of the door leaf and the maintenance of a safety clearance may be necessary. Thus, for example, it should be noted that simple overhead doors are pivoted depending on the kinematics with its lower edge to the outside, so that then parked in front of the opening to be closed vehicles, objects or people there can collide with the door leaf. In addition to a danger from the opening and closing movement, the door leaf itself can be damaged to some extent.

In order to warn a user accordingly and to indicate the operating state of the gate in an opening and closing movement, known in the prior art display devices on the type of traffic lights. A corresponding display is for example in the DE 10 2007 051 264 A1 described, but such a display can be perceived only on one side of the door. Optionally, to ensure safe operation, appropriate displays are to be provided both on the inside and on the outside of the door.

The DE 20 2014 101 305 U1 discloses a bar in the manner of a switching strip, which has at its outer edge in a recess open to the outside a light source. The contact strip described can be arranged on a gate, so that then results in combination with a suitable controller and a door drive a generic design.

Since the lighting means is held in a form-fitting manner by the associated recess, only a small opening angle remains, in which light can be emitted, so that illumination takes place only in a comparatively small angular range. In addition, the light source is exposed as the foremost part of the bar considerable stress.

Against this background, the present invention seeks to provide a door with a door drive, a controller and a light-changing device, which is characterized by particularly good functional properties of the light-changing device.

The object of the invention and solution of the problem is a gate according to claim 1. Starting from a generic embodiment, the invention provides that the end strip has a preferably over the width of the door leaf extending translucent section, wherein the light-changing device is submitted to the translucent section illuminate.

The translucent portion thus has a translucent but refractive material, which is perceived by a user usually as milky. In contrast to a transparency, the material is therefore not transparent and transparent, but only translucent, which means using the light-changing device a particularly uniform, well-visible from different directions lighting is possible. At least one light source of the light-changing device illuminates the translucent section, whereby the light is refracted and evenly distributed in the manner of a frosted-glass pane.

This also results in the advantage that a larger, even bearing portion of the end strip can be formed from the translucent material, so that no shadowing or the like can result, whereby the emission angle of light is maximized.

According to the invention, a light changer is provided, which can emit light in different colors and / or different light pulses, whereby a user of the operating state is displayed. Preferably, the light-changing device is intended to display at least two different colors. For example, in the case of an opening or closing movement of the door leaf, a blinking and / or a warning color warn a user. Suitable, for example, a red hue indicating the manner of a traffic light that the opening to be closed by the door leaf can not be passed and, if appropriate, a safety margin is observed.

If the door leaf then reaches the open position at the end of an opening movement, a color change to green, for example, can take place. A user is then indicated that there is no danger and the opening released by the door leaf can be passed.

When closing the door leaf, a warning in the form of a warning color and / or a flashing is expediently issued during the movement, in which case different options are conceivable when the closing position is reached. Thus, for example, the closing process can be acknowledged by a short change to green the user. Alternatively, it is also possible to disable the light-changing device or to display a different color.

According to a preferred embodiment of the invention, the controller and the light-changing device are configured such that in a standby state of the light-changing device, a first light color, in a first operating state, a second light color and in a second operating state, a third light color is emitted. The three light colors are different from each other. The term light color does not strictly refer to a particular wavelength or a wavelength range, but to the color perception of a user, whereby white light is understood in this sense as light color.

For example, white may be provided as the first light color, ambient lighting then being realized in a particularly advantageous manner in the standby state. The standby state can be activated in different ways. It is thus possible that permanent white light is emitted in order to achieve ambient lighting under all circumstances. Appropriately, the delivery of the first light color is delivered but only in the dark or a corresponding request by a user.

The activation can be done for example by a brightness sensor, a motion detector or a timer.

For example, a user request may be triggered outside the actual signal for opening and closing by a switch, a radio remote control, or even by electronic communication means. For example, the control can also be configured with so-called geofencing functionalities, wherein the standby state is triggered, for example, when a mobile device of a user logs on to a local WLAN or via a corresponding positioning function and data communication an approximation is detected. In addition to mobile phones, modern motor vehicles already have corresponding positioning and telecommunication systems, so that then, when the vehicle approaches, the standby state and thus the delivery of the first light color is activated. The result then is the advantage that, for example, a courtyard and entrance area is illuminated for a user and also the position of the door itself is immediately apparent.

The first operating state corresponds, for example, to the opening or closing movement in which the door leaf is moved and the opening closed in front of the door leaf is not to be passed by a user. The light changer then emits red light, for example, to warn a user accordingly.

Upon reaching the open position after an opening operation, the control is in the second operating state, in which the door drive is stopped and a third light color, such as green light is emitted. A user is then indicated that the opening movement is completed and the closed by the door leaf opening can be safely passed.

In the context of the invention, various possibilities of embodiment arise when the door leaf remains in the open position over a longer period of time. For example, first a transfer to the standby state can take place, in which case white light is emitted as ambient lighting, before the light-changing device can be deactivated in a time-controlled manner.

During the closing movement, the door is in the first operating state in which the second light color, in particular red, is emitted. After completing the closing process, the controller can then optionally first in the second operating state and then switch to the standby state or directly into the standby state, in which then an ambient lighting with the first light color, in particular white takes place.

Since the end strip according to the invention has a translucent section, the light can be radiated in different directions and in particular in the direction of the outside as well as the inside of the door.

According to a preferred embodiment of the invention it is provided that the end strip has an elastic end portion in the manner of a seal, wherein the translucent portion between the elastic end portion and the lower edge of the door leaf is arranged. The translucent portion can then be formed, for example, by a translucent plastic profile, which is attached on the one hand to the lower edge of the door leaf and on the other hand receives the elastic end portion, which can be formed by a conventional elastic end seal. Such a seal made of elastic material may for example be held positively in a groove or the like.

According to an alternative development, it is provided that the translucent section and the end section are formed as a co-extrusion profile of different plastics. There is then no danger that the seal will be lost.

The translucent portion is then usually formed of a non-elastic plastic, wherein the translucent portion is preferably attached to its opposite end portion of the side via a positive connection to the door leaf. Particularly preferred is a Rastausformung, which can be brought into engagement with a corresponding receptacle on the lower edge of the door leaf, so that then the end strip can be mounted very easily and, if necessary, also be replaced later.

For the production as a coextrusion profile of different plastics thermoplastic elastomer can be provided for the elastic end portion. The translucent section can be formed, for example, from ABS, polycarbonate or suitable polyolefins such as PP and HDPE, although mixtures of the polymers mentioned merely by way of example also come into consideration. Unless the polymers are inherently translucent, suitable additives such as pigments may also be added.

According to a preferred embodiment of the invention, the translucent portion has a hollow chamber, wherein at least one light source of the light-changing device is arranged in the hollow chamber. The arrangement of the at least one light source in the hollow chamber this is optimally protected, whereby a particularly uniform light emission can be achieved by the illumination from the inside and the scattering properties of the translucent section.

For example, the light source may be band-shaped or strip-shaped and have a multiplicity of LEDs. Suitable bulbs are available in various designs, with groups of differently colored LEDs and / or correspondingly controllable multicolor LEDs for a color change can be used. This distinction refers to the components to be interconnected and is not strict insofar as common multicolor LEDs are ultimately formed from an interconnection of several different semiconductor junctions (and thus several different LEDs) in one component.

As previously explained, the door leaf is preferably formed from a plurality of hingedly interconnected panels, with other embodiments such as overhead doors, roller doors or the like are not excluded.

The connection of the light changer to the controller can be done by a corresponding connection cable. In principle, however, a wireless energy and data transmission by antennas or the like is conceivable.

In addition to at least one lamp, other components of the light-changing device such as a controller and a buffer memory can be provided on the terminal block or on the door leaf. If corresponding electronic components are introduced together with the at least one light source in a hollow chamber, there is an optimal protection against damage.

The invention will be explained in the following with reference to a drawing showing only one exemplary embodiment. Show it:

Fig. 1:

a gate with a door leaf and a closing border at a lower edge of the door leaf,

Fig. 2:

a detailed view of the lower edge of the door leaf with the closing end strip.

Fig. 1 shows a gate in the form of a sectional door on a garage. The door panel 1 is formed of a plurality of horizontally oriented panels 2 which are hinged together about horizontal axes, whereby the door panel 1 can be moved along a guide 3 between a vertical closed position and a horizontal open position. For this purpose, the gate has a door drive 4 with a built-in control in the housing of the door drive 4, wherein also a subsequently explained further light-changing device is also connected to the controller.

At the bottom of the door leaf there is a closing strip 5, which has a translucent, ie translucent, section 6 and, at the side remote from the door leaf 1, an elastic end section 7 directly at the lower edge of the door leaf 1.

As can be seen from the detailed view of Fig. 2 results, the translucent portion 6 and the elastic end portion 7 are formed together as a coextrusion of different plastics, wherein for the elastic end portions 7 in the manner of a sealing profile thermoplastic elastomers (TPE) and for the translucent portion 6 is a non-elastic, rigid and durable plastic such as ABS, polycarbonate or suitable polyolefins such as PP and HDPE, as well as mixtures of the polymers exemplified only come into consideration.

In the illustrated embodiment, the translucent portion 6 forms a hollow chamber 8, in which a band-shaped lamp 9 is used with a plurality of LEDs, which allow a color change. Can do this be provided either for the different colors different groups of LEDs or individual components on the type of multi-color LEDs allow a color change.

The arrangement of the light source 9 in the hollow chamber 8 ensures optimum protection against damage. In addition, a particularly uniform emission of light in a wide angle range is guaranteed. Of the Fig. 2 It can be seen that a radiation is ensured both on the front and the back of the door panel 1.

The controller and the light changer are arranged such that in a standby state, for example when the door leaf is closed, a first light color, in particular white light, is emitted. If the door leaf 1 as in Fig. 1 shown is moved in an opening or closing movement, the door is in a first operating state in which a second light color, such as red light is emitted. A user recognizes that the door leaf is being moved and the opening closed by the door leaf 1 is not to be passed and, if necessary, a safe distance must be maintained.

At least when the door leaf 1 has then reached the opening position, in a second operating state, the delivery of a third light color, such as green light may be useful to indicate to a user that the opening can be safely passed.
