From the EP 1 911 983 A1 a hinge with the features of the preamble of claim 1 is known.

It would be desirable to expand the pivoting possibilities of a door of dispensing devices in order to be able to simply move the door of the dispensing device protruding into the aisle of a supermarket, for example, and to pivot it further in a defined manner.

It is therefore the object of the present invention to develop a hinge for an output device of the type mentioned in the introduction in an advantageous manner, in particular in that the hinge provides a non-destructive and reversible panic opening function of a door of an output device.

This object is achieved according to the invention by a hinge with the features of claim 1. According to the invention, a hinge is provided for an output device, the hinge being essentially rod-shaped and / or tubular for attachment to a door of the output device, the Hinge has at least one base body and an insertion rail arranged on the base body for the door, the door being inserted into the insertion rail and in the insertion rail in the assembled state is held, wherein at least one damping device and at least one panic hinge device are provided in the base body, the hinge has a first opening area with a first opening resistance and a second opening area with a second opening resistance, the first opening resistance being less than the second opening resistance, the second opening resistance being determined by the panic hinge device, and that in the second opening area only a damped and / or inhibited pivoting is made possible by the second pivoting resistance, the second pivoting range having at least a first angular range and at least one second angular range following the first angular range, the opening force being increased in a first angular range when the panic function is used and the hinge being damped in the second angular range a lower opening force than to open in the first angular range.

The invention is based on the basic idea of providing a hinge for an output device which can essentially be completely accommodated in a side strut of the output device. As a result, the risk of injury to users of the dispensing device can be reduced. In particular, it is conceivable to be able to completely retract the hinge in a strut of the dispensing device or even to form a strut of the dispensing device entirely through the hinge. The provision of a damping device and a panic hinge device in the base body of the hinge makes it possible to provide a damped opening or closing movement. The panic hinge device makes it possible, after a first opening angle of the door, to provide a second opening angle which can be opened, braked, inhibited or damped. Such a configuration makes it possible to provide a panic function. In the case of dispensers for unpackaged goods, in particular baked goods, which are set up in retail stores, the opened door of the dispenser can protrude into the aisle to a considerable extent. If there is a dangerous situation in the retail store, the aisles also serve as escape routes and the open door can be an obstacle. The door of the dispensing device can be pushed open further by the panic hinge device, ie the opening angle of the door can be increased, which makes it possible will continue to open the aisle. The door of the dispenser therefore does not have to be closed, but can be opened further by overcoming the predefined resistance. This function is also called panic function.

The division of the swing-open resistance in the context of the panic function means that the opening movement is initially made more difficult as part of the panic function, but preferably initially only with a moderate increase in the opening force to be applied in the first angular range. As soon as the first angular range is exited as part of the panic function, the door should be able to be opened quickly and with less resistance, so that the opening force to be applied is then reduced again in the second angular range compared to the first angular range.

Furthermore, it can be provided that the base body and the insertion rail have essentially the same length, in particular wherein the insertion rail extends essentially over the entire length of the base body. This ensures that a uniform introduction of force from the insertion rail into the base body and vice versa is made possible. A better fastening for the door is made possible overall. In general, this more even distribution of force and torque enables an improved load on the entire hinge structure, which is why the base body can be made much slimmer and smaller, for example.

The insertion rail and the door can have essentially the same length. This further enables better fastening and better gripping of the door in the insertion rail. It is conceivable, for example, that the push-in rail and the door are pushed into one another, for example in this context the push-in rail is designed as a U-profile into which the door is inserted.

The door can at least partially consist of a transparent material. It can in particular be provided that the door is a glass door or at least has a glass pane. This makes it possible to look inside the dispenser.

Furthermore, the hinge can have a gas spring, by means of which the movements of the hinge can be supported and / or damped. In particular, it is conceivable that the gas spring does not provide any resistance when the door is opened and brakes the door when the door is closed, because the gas in the gas spring is only displaced when the door is closed and it is therefore necessary to work against this resistance. In this way, a decelerated door closing movement or even a soft-close function (e.g. in connection with another damping element) can be achieved. In this context, it is particularly conceivable that the gas spring is arranged in the base body of the hinge. Furthermore, it can be provided that the hinge has, in addition or as an alternative to the gas spring, a further elastic element, by means of which the movements of the hinge can be supported and / or damped. For example, such an elastic element can be a mechanical damping element or a hydraulic damping element (e.g. oil damper). A combination of the mechanical and the hydraulic damping element is also conceivable in this context.

It is particularly conceivable that the panic hinge device has a gas spring.

The first pivoting area can have an opening angle of the door from the closed state of the door to an opening angle of the opened door in a range from between approximately 80 ° to approximately 110 °, in particular in a range between approximately 85 ° to approximately 100 °, preferably from about 85 ° to about 90 °.

This area is sufficient for the normal operation of the dispenser and enables customers to operate the dispenser comfortably. A further opening than 90 ° is usually not necessary for the first swivel area.

The second swing-open area is necessary in connection with the panic function and is considered sufficient in this area to push the door open further in a panic situation when the panic function is needed, so that a Corridor of the market is released sufficiently to allow escape through the aisle.

Furthermore, it can be provided that the insertion rail arranged on the base body is arranged pivotably on the base body. This creates additional movement options.

It is also possible that the first angular range extends over an opening angle of approx. 90 ° to approx. 105 ° and / or that the second angular range begins up to approx. 105 °, in particular wherein the second angular range extends over an opening angle of approx. 105 ° extends up to approx. 180 °.

Furthermore, it can be provided that the first pivoting area with its first pivoting resistance requires an opening force of approximately 5 N to 8 N (approximately 5-8 Newtons). In particular, it can be provided that the opening force is approximately 5 N. The advantage is that, due to the comparatively low opening force, simplified opening is made possible in the first swing-open area.

In particular, it is also conceivable that the second swivel-open area in the first angular area requires an opening force of approximately 9 N to approximately 12 N (approximately 9-12 Newtons). In particular, it can be provided that the opening force is approximately 9-10 N. The effect is that in this angular range (e.g. from approx. 85 ° -90 ° to approx. 105 ° -110 ° an increased opening force is required to push open the door (so-called panic function = enabling the door that has already been opened to be pushed open further increased effort).

It is also possible that the second swing-open area in the second angular area requires an opening force of approx. 8 N (approx. 8 Newtons). This angular range can begin, for example, between approximately 105 ° and 110 ° and end at approximately> 160 °.

It is basically conceivable that the closing forces are selected to be comparable.

In the closing direction it can be provided that a closing force of approximately 8 N is required in an angular range between approximately 160 ° to> 110 ° -105 °. Further in the closing direction it can be provided that a closing force of approximately 9-10 N is required from an angle of approximately 110 ° to approximately 105 ° to approximately 90 ° to approximately 85 °.

From an angle of approx. 90 ° to 85 °, the effect of gravity is sufficient as the closing force in the closing direction. It is conceivable to design the hinge for this area in such a way that it is designed to be self-closing but damped.

Damping is not absolutely necessary in the closing direction below, for example, 20 °. It can preferably be omitted in this area.

It is conceivable that the closing time in the closing direction is approximately 10 seconds.

It is also possible that the aforementioned forces, i.e. the opening and / or closing forces, with respect to their amounts, can be varied by approx. 1-2 N. In this case, it is preferable to proceed in such a way that the other values are then also adapted accordingly, so that the corresponding force relations are maintained.

Furthermore, the present invention relates to an output device with at least one hinge.

The dispensing device can have at least one door which is pivotably hinged to a body of the dispensing device by means of the hinge, such that the door opens in the first position of the hinge in a range from the closed state of the door to a first opening position with a first opening angle and that the door can be opened in the second position of the hinge, in particular to form a panic opening function, into a second opening position with a second opening angle that is larger than the first opening angle.

The first opening angle can be selected in a range between approximately 80 ° to approximately 110 °, in particular in a range between approximately 85 ° to approximately 110 °. This area is sufficient for the normal operation of the dispenser and enables customers to operate the dispenser comfortably.

In addition, it can be provided that the second opening angle is selected in a range between approximately 105 ° to approximately 180 °, in particular in a range between approximately 105 ° to approximately> 160 °. This area is sufficient to further extend the door in a panic situation when the panic function is needed to impose that the aisle of the market is cleared sufficiently to allow escape through the aisle.

Further details and advantages of the invention will now be explained in more detail with reference to an embodiment shown in the drawings.

Fig. 1 shows a perspective view of an embodiment of a hinge 10 according to the invention for an output device 12 (cf. Fig. 2 ).

The hinge 10 is essentially rod-shaped or tubular for attachment to a door of the dispensing device 12 (cf. Fig. 2 , here two doors 14, each with a hinge 10).

The hinge 10 has at least one base body 20 and an insertion rail 22 arranged on the base body 20 for the door 14.

In principle, it is conceivable that the insertion rail 22 is arranged rigidly on the base body 20. However, it is also conceivable that the insertion rail 22 is pivotably arranged on the base body 20.

The insertion rail 22 is U-shaped and can grip the door 14 on both sides.

At least one damping device 24 (indicated by reference number 24) and a panic hinge device 26 (indicated by reference number 26) are provided in the base body 20.

The damping device 24 can be a gas damper or an oil damper.

The panic hinge device 26 is, for example, also a gas damper or an oil damper, the panic hinge device 26 being designed such that it does not engage in a first opening angle of the door 14 between 0 ° to 90 ° and only from an opening angle of over 90 ° to about 160 ° a braked, but further opening of the door 14 allows.

How further out Fig. 1 and Fig. 2 can be seen, the base body 20 and the insertion rail 22 have essentially the same length.

The insertion rail 22 slightly projects above the body of the base body 20 at both ends of the base body 20.

The insertion rail 22 thus extends essentially over the entire length of the base body 20.

How further out Fig. 2 it can be seen that the insertion rail 22 and the door 14 are essentially of the same length, that is to say they have the same length.

The door 14 shown is in each case a transparent door, here a glass door, on which the handle 14a or 14b are provided for gripping the door 14.

How further out Fig. 2 it can be seen, the dispensing device 12 has a front area which is closed by the door 14 (cf. Fig. 4 ) can be closed or opened.

The front area itself has a backward slope of approximately 10 ° with respect to the vertical.

A plurality of inserts 28 are provided in the interior of the dispensing device 12, on which baked goods, for example, can be presented and sold.

The dispensing device 12 has a base frame 30 which is formed from a plurality of rod-like struts 32 of different lengths.

The dispensing device 12 is articulated to a body 34 of the dispensing device 12 by means of the hinge 10, the body 34 being essentially defined by the base frame 30.

However, the base body 20 has an essentially identical diameter to the rod-like struts 32, so that the hinge 10 can be inserted into the base structure of the frame 30 without problems and is therefore also perceived as one of the rod-like struts 32.

In Fig. 2 the door 14 is shown in the open state at the end of a first pivoting area. The first pivot area is defined such that it extends from the closed door 14 with an opening angle of 0 ° to an opening angle of approximately 90 °.

In this first opening area, the hinge 10 offers a first opening resistance that is less than the second opening resistance that occurs in the second opening area when the door 14 is opened with an opening angle of greater than 90 °.

The second swing-open resistance is determined by the panic hinge device 26, and in the second swing-up area only a damped and / or inhibited swing-open is made possible by the second swing-open resistor.

The function of the hinge 10 and its functional interaction with the dispensing device 12 will now be described as follows:
To dispense unpacked goods, such as baked goods, the dispenser 12 is usually positioned in aisled supermarket aisles.

In order to be able to dispense the baked goods, the door 14 which is pivotable relative to the body 34 of the dispenser 12 must be opened by a customer of the supermarket.

Under normal operating conditions of the dispensing device 12, the door 14 is only opened from the closed position of the door 14 to its first open position or to the end of the first pivoting area (see Fig. 2 ).

In this position, the door 14 has an opening angle of approximately 90 °.

The closed position of the door 14 is in Fig. 4 shows.

When the door 14 or the doors 14 have or have reached their first opening position, they block or block a not inconsiderable area of the aisle or hallway in which the dispensing device 12 is positioned.

If a panic situation arises while the door 14 is in its first opening position, the door 14, which projects into the aisle of the supermarket to a not inconsiderable extent, represents an additional considerable security risk for the customers of the supermarket who are in the panic situation.

In this case, the dispensing device 12 or the hinge 10 is designed to be transferred to the second open position of the door 14, as shown in FIG Fig. 3 is shown. This is particularly necessary if the customer should not be able to properly move the door 14 into its regularly closed position in the panic situation (cf. Fig. 4 ) to transfer.

The hinge 10 is then transferred from a first position to a second position during the transition from the first opening position of the door 14 to its second opening position, which is located at the end of the second pivoting area. The second opening resistance, which is determined by the panic hinge device 26, must additionally be overcome.

However, an opening of the door 14 or of the doors 14 beyond the opening angle of 90 ° into a position with an opening angle of approximately 160 ° is as in FIG Fig. 3 shown, and also possible up to about 180 °, as described below.

In this context is also in Fig. 5 the basic and schematic opening movement of the door 14 of the dispenser 12 is shown.

As previously explained, the normal opening angle of hinge 10 and door 14 is approximately 90 °.

Within this angular range, the opening force in relation to the outer edge of the door 14 should be approximately 5 N (approximately 5 Newtons).

The panic function should then start from an opening angle of 85 ° -90 ° to approx. 105 ° -110 °.

Within this angular range, the opening force should then be approx. 9-10 N (approx. 9-10 Newton) based on the outer edge of the door.

From an opening angle of approx. 105 ° -110 ° to approx.> 160 °, the hinge must be able to be opened further in a damped manner in order to avoid damage to the door 14 or the hinge 10. The opening speed is irrelevant.

Within this angular range, the opening force should then be approx. 8 N (approx. 8 Newtons) based on the outer edge of the door.

An opening of 160 ° is sufficient since the door 14 finds a stop at the handle 14a, 14b of the neighboring door. A large number of output devices 12 are usually arranged next to one another. On the first output device 12, which has only one output device 12 adjacent to it, there is a stop surface / area on a side panel, not shown in detail.

The opening time of the door 14 is a few seconds, preferably less than 5 seconds.

Furthermore shows Fig. 6 accordingly the schematic closing movement of the door 14 of the dispensing device 12.

The hinge should be at least partially continuously damped from approx. 0 ° to approx. 90 ° opening angle in the closing direction and close automatically or automatically. The closing time in this angular range is approx. 10 s (approx. 10 seconds).

Gravity serves as the closing force, so that a self-closing but damped closing movement takes place (so-called damped hinge).

Damping below 20 ° is not absolutely necessary and is also not provided in the exemplary embodiment shown.

As a result of actuating the panic function (damped), the hinge 10 is manually pivoted back to the opening angle of approximately 90 ° in order to then be able to guarantee the normal or automatic and damped closing function, as already described above.

Within an angular range of approx. 180 ° to approx. 105 °, the closing force based on the outer edge of the door should be approx. 8 N (approx. 8 Newton).

Within an angular range of approx. 110 ° to 105 ° to approx. 90 ° to 85 ° (within the angular range of the panic function), the closing force in the closing direction should be approx. 9-10 N (approx. 9-10 Newton) in relation to the outer edge of the door be.

In the 5 and 6 the opening movement of the door 14 is shown counterclockwise and the closing movement of the door 14 is shown clockwise. This representation is to be understood purely as an example.

In this context, it is also conceivable that the opening movement of the door 14 is clockwise and the closing movement of the door 14 is counterclockwise.
