Showcase/ especially for advertising purposes

The invention relates to a display case, in particular for advertising purposes, which has a rectangular frame enclosing an interior space made of hollow profiles that are connected to one another by corner connectors and has, on at least one side, a hinged window that can be pivoted upwards and locked, wherein an information carrier is arranged in the hinged window.

Display cases, particularly for advertising purposes, with flat information carriers illuminated by a light source, located in a door closed by a transparent pane, are known. DE-AS 25 41 040 describes a display case with a rectangular frame, consisting of a profile, in particular an extruded metal profile, with corner connectors and with fastening parts for a window sash or for sliding glass doors, which is characterized in that the profile is designed as a hollow profile with extensions attached to the outside, enclosing the rear wall and front wall, that the rear wall is attached to the extension facing the rear with the help of snap-in rails, that window guide parts are attached within the extension of the hollow profile facing the front, so that the outer wall of the window profile is approximately flush with the extension facing the front of the display case, and that the inside of the window profile rests against the slightly protruding side edge of the inside of the hollow profile when the display case is closed.

This well-known display case enables the construction of a relatively torsion-resistant display case even with a width of up to 2.50 m. The hollow profile requires a relatively high manufacturing effort, particularly due to the different design of the sides, which form the front wall and the rear wall. The window sash of this well-known display case opens sideways. When such a display case is set up outdoors, such a side sash, in particular

If no supports are provided for it, wind forces will attack and damage it. In addition, the design options for such a display case are very limited.

DE 31 13 649 C2 also discloses a box-shaped visual advertising element with a frame made of extruded aluminum profile bars that are mitred at the corners of the frame, with each bar having the receiving part of a rail-shaped plug connection along one of its profile edges and the engaging part of a rail-shaped plug connection along its other profile edge. The aim of this solution is to change the width of the frame. This solution enables visual advertising elements to be designed in a more varied way. However, it requires a complicated structure of the profiles used and therefore a high level of manufacturing effort. Furthermore, the strength of the frame construction is reduced with such plug connections.

The invention is based on the problem of creating a display case, in particular for advertising purposes, which has a rectangular frame enclosing an interior space made of hollow profiles that are connected to one another by corner connectors and at least on one side has a hinged window that can be pivoted upwards and locked, with an information carrier arranged in the hinged window, which makes it possible to use extruded profiles as hollow profiles, whereby with the same cross-section and different solutions for the hollow profiles, display cases of different sizes can be produced as wall and free-standing display cases, in which the frame has a high level of strength, in particular also torsional rigidity, so that these display cases can also be set up outdoors.

The problem is solved by the hollow profile from which the frame is constructed being designed in its cross-section as a chamber profile, the chamber of which is formed by a horizontal upper web forming the outer wall of the frame and a

DE7 86RÖ01

Interior space delimiting horizontal lower web and the chamber laterally delimiting vertical webs connected to the horizontal webs, the upper web having a rear section that projects beyond the rear vertical web and a horizontal front section that projects beyond the front vertical web and forms a right angle with these, the rear vertical web forming a smooth surface, while the front vertical web is divided into several sections that are offset inwards from top to bottom in the direction of the vertical central axis of the hollow profile and are connected to one another by a horizontal intermediate web, the corner connector being arranged in the part of the chamber that is delimited by the horizontal webs as well as the rear vertical web and the lower section of the front vertical web, a door hinge being arranged on the hollow profile forming the upper horizontal part of the frame, at the right angle between the front section of the horizontal web and the upper section of the vertical web, on which the folding door can be pivoted about its longitudinal axis is arranged pivotably, with a gas spring being arranged between the folding door and the frame, which holds the folding door in its open position, which is arranged with its upper part in the area of the upper half of the folding door and with its lower part on the hollow profile forming the vertical part of the frame, with a support being arranged in the interior of the display case, to the ends of which a seal is attached, against which the folding door rests in the closed state, sealing the interior from the outside, with the gas spring being in a vertical position in a section behind the seal and with a lock being arranged on the hollow profile forming the lower horizontal part of the frame, which holds the folding door in its closed position.

A simple and tight rear closure of the display case is achieved if a rear wall is arranged flush in the space formed by the section of the upper horizontal bar that protrudes beyond the rear vertical bar.

DE786RÖ01 :**. : '

In a further embodiment of the invention, in particular for display cabinets, it is possible for a hinged window to be arranged on both sides of the frame, whereby the hollow profile has a mirror-image formation on both sides that accommodates the hinged door.

In order to increase the torsional rigidity of the frame of such a display case while maintaining a low dead weight, it is advantageous if the lower horizontal bar consists of two side sections and a middle section, the middle section being at a greater distance from the upper horizontal bar than the side sections and the width of the middle section being smaller than the width of the corner connector, so that it rests on the side sections.

When setting up the display case according to the invention outdoors, it is important that the information carrier, for example advertising posters, is also visible in the dark. For this purpose, lighting, preferably fluorescent tubes, can be arranged on the carrier that holds the seal for the folding door.

In order to avoid a design that interrupts the external design of the frame and to achieve a secure connection when using a corner connector, it is advisable if the hollow profiles used to produce the frame are mitred and have an adhesive or mortise joint.

In a further development of the invention, one or more smaller frames made of hollow profiles in the form of extruded profiles and corner connectors are arranged on the frame of the display case, which are firmly connected to the frame of the display case, which forms the strength of the same. This makes it possible to have a different aesthetic design of the display cases using additional extruded profiles.

DE786RÖ01

A preferred embodiment consists in that the hollow profile is designed as a closed profile body with a freely configurable visible surface and a base surface that encloses a chamber, the base surface being flat and in which there are arranged several adjacent, mutually delimited by webs, preferably U-shaped grooves that are alternately open to the chamber and the base surface, with a clamping element being arranged on the end face of the laterally arranged panels that is closed towards the chamber and a projection that projects into the chamber is arranged on the end face of the middle groove that is closed towards the chamber and that is opposite an identical projection arranged on the opposite inside of the visible surface.

In a further embodiment, the corner connector has a cap whose cross-section corresponds to the cross-section of the visible surface of the hollow profiles to be connected and whose upper base surfaces are arranged at right angles to one another, whereby the corner connector has a base body that supports the cap and provides the required stability, on which plug-in elements are arranged that protrude forwards from the flat base surfaces, engage in the grooves of the hollow profiles to be connected and are fixed by the clamping elements, whereby the base body has a vertical slot in its middle area into which the projections of the hollow profile engage. The rectangular frame formed by the hollow profiles and the corner connectors can itself form the frame enclosing the display case, whereby elements that close off the display case at the sides and hold information carriers are arranged in the grooves that are open towards the base surface.

A further development of the invention consists in the fact that the hollow profile forming the lower horizontal part of the frame has a locking mechanism that holds the folding door in the closed position, two bolts arranged on the sides and a

DE7 86RÖ01 : : : : : · : :··*:.:

the showcase has a locking part which is accessible from below, whereby the latches and the locking part are operatively connected to one another by a shaft which extends in the longitudinal direction of the hollow profile, is rotatable about its longitudinal axis and is provided with cams in the area of the latches.

It is expedient if the locking part is arranged in a holder on the hollow profile on the underside of the display case, with a pivot pin that can pivot about its longitudinal axis being arranged vertically in the holder, at the upper end of which a cross pin is attached at right angles to this, which is operatively connected to a pin arranged on the shaft, with the shaft performing a pivoting movement about its longitudinal axis when the pivot pin rotates about its longitudinal axis, whereby the respective cam assigned to the bolt rests against it and this thereby assumes an open position against the force of a spring assigned to it, while the bolt in the closed position grips behind a holder arranged on the folding door under the force of the spring. The spring holding the bolt in its closed position can be attached to the hollow profile and designed as a leaf spring.

The solution according to the invention creates a display case which, with a simple structural design, particularly through the use of extruded profiles with shapes that are simple to manufacture, can be used in a variety of ways and can be manufactured in different sizes. It is possible to achieve different aesthetic designs by combining different extruded profiles. The use of folding doors with gas springs offers a high level of security for display cases arranged outdoors, particularly for free-standing display cases that are accessible from two sides. Secure locking is also guaranteed for this.

The invention will be explained in more detail below using an exemplary embodiment. The accompanying drawings show:

Fig. 1 shows the upper part of a display case, particularly for advertising purposes. This has a frame 1 consisting of hollow profiles 2. A folding door 3 is arranged on the frame 1. The upper end of this is attached to the frame 1 so that it can be swung upwards. The opening angle of the folding door 3 is preferably 45°. It is held in its open position by a gas spring 5. This ensures that even with large display cases, the folding door 3 cannot be pushed away by wind forces, thus preventing damage to the display case. The gas spring 5 is pivotally attached with its upper end to the folding door 3 and with its lower end to the hollow profile 2 forming the side wall of the frame 1. With larger display cases, a gas spring 5 can be arranged on each of the two side walls. When the folding door 3 is closed, the piston rod is pressed into the gas spring 5 and is pushed together in the display case behind the seal for the folding door 3. In the folding door 3, the information carrier is arranged in a known manner behind a pane of glass, preferably made of single-pane safety glass. This can be a poster, for example an advertising poster. However, it is also possible to

DE786RÖ01 '. &igr; : t :* : : '"i. :

Other information carriers, such as timetables, can be provided in the display case. The information carrier can of course also be applied directly to the glass pane in the form of reverse glass painting.

On the lower side of the display case, not shown in Fig. 1, there is a locking mechanism for the folding door 3, as shown in Fig. 6 and 7. The back of the display case is flush with a rear wall 19, as shown in Fig. 1.

A preferred design for free-standing showcases is that a folding door 3 is arranged on both sides of the showcase. A corresponding hollow profile 2 is shown in Fig. 3.

A support 6 is arranged in the interior 7 of the display case. Light elements, such as fluorescent tubes, are arranged on this in a manner known per se to illuminate the display case. In order to achieve an even distribution of light, panes made of frosted glass are preferably also provided. The display case can be designed as a free-standing display case or as a wall display case.

In Fig. 2, the upper end of the display case is shown in an enlarged view according to Fig. 1. From this Fig. 2 it is clear that the frame 1 consists of hollow profiles 2 that have the same cross-section. This makes it possible to easily produce display cases of different sizes using a hollow profile. These then only have a different length. In order to achieve a simple connection of the hollow profiles 2 to form a frame 1, preferably a rectangular frame 1, they are mitered and connected to one another by corner connectors 13. The corner connectors 13 are designed in a manner known per se. The basic shape of the hollow profile 2 is a rectangular chamber profile, which achieves the necessary high strength. The structure of the hollow profile 2 is described using Figs. 2 and 3. The hollow profile 2, as shown in Fig. 3, is

DE7 86RÖ01 ; : : ! : «

is designed for a display cabinet with folding doors 3 arranged on both sides, whereby this has a slightly different structure to increase the strength, in particular the torsional rigidity. The hollow profile 2 has a horizontal upper web 8, which is the outer wall of the frame 1. Its horizontal lower web 9 forms the inner wall of the frame 1. This is, as shown in Fig. 2, just as continuous as the upper web 8.

In the hollow profile shown in Fig. 3, the lower web 9 consists of two lateral sections 9' and a middle section 9". To increase the strength of the hollow profile 2, this middle section 9" is at a greater distance from the horizontal upper web 8 than the lateral sections 9'. The horizontal webs 8; 9 are connected to one another by vertical webs 10; 11 arranged at a predetermined horizontal distance from one another, whereby a closed chamber 12 is formed. So that the hollow profile 2 designed as a chamber profile can form the frame 1 for the display case, it is subdivided and provided with corresponding projections or sections.

As shown in Fig. 2, the horizontal upper web 8 of the hollow profile 2 has a rear section 8" which projects beyond the rear vertical web 10. This creates a rear, laterally enclosed section. After the frame 1 has been assembled, the rear wall 19 (Fig. 1) is inserted at this point and thereby closes off the rear of the display case flush. The upper horizontal web 8 also has a horizontal front section 8 ¹ which projects beyond the front vertical web 11 and forms a right angle with it. Projections 14 are provided on the section 8 ¹ and the web 11. A door hinge 4 is attached between the projections 14 of the hollow profile 2 forming the upper horizontal end of the frame 1. The folding door 3 is pivoted upwards into its open position on this door hinge 4.

pivotally mounted (Fig. 1). The front section 8' of the horizontal upper web 8 protrudes so far forward that the flap door 3 in its closed position is flush with its front edge. The front vertical web 11 consists of two sections 11', with the lower part being offset to the rear compared to the upper part. The two sections 11' are connected by a horizontal intermediate web 15, which divides the chamber 12.

A vertical projection 16 can be arranged on the inside of the upper web 8. This lies in the same plane as the lower section II ¹ of the vertical web 11. This forms a part of the chamber 12 which is delimited by the horizontal webs 8; 9, the rear vertical web 10 and the lower section 11' of the front vertical web 11 and the projection 16. The corner connectors 13 connecting the individual hollow profiles 2 to form the rectangular frame 1 are arranged in this. As already explained, this design and, if applicable, the subdivision of the lower horizontal web 9 shown in Fig. 2 achieves a high level of strength, in particular bending and torsional rigidity, of the frame 1. Furthermore, the assembly option when inserting the corner connector 13 is improved. In addition, this structure reduces the weight of the frame 1 and thus that of the display case. The horizontal lower web 9 forms a closed right angle with the rear vertical web 10. On the front side, the lateral section 9' projects beyond the lower section 11' of the vertical web 11 arranged at right angles to the latter. The horizontal web 9 forms, as explained, the inner wall of the display case and laterally delimits its interior space 7.

The hollow profile 2 shown in Fig. 3 is, as explained, intended for a frame 1 on which a folding door 3 is arranged on both sides. This practically has two advantages.

DE786RÖ01 : : &igr;&igr;&igr;'&igr; :···:.:

the sides. The back with the rear wall 24 is omitted. The different structure of the hollow profile 2, particularly in the area of the lower horizontal web 9, has been explained.

As explained in Fig. 1, the support 6 is arranged in the interior 7 of the display case. In Fig. 2 it is shown that a seal holder 17 with a seal 18 is arranged on its ends. The hinged door 3 rests against the seal 18 when closed. This seals the display case on the outside.

In a further embodiment of the invention, a hollow profile 20 can be provided, the cross section of which is shown in Fig. 4. This hollow profile 20 forms a frame of high stability with a corner connector 21 (Fig. 5). This frame can be used in different ways. A preferred embodiment consists in it being placed on the frame 1 made of the hollow profile 2 and fastened to it, so that it serves for the aesthetic design of a display case. Since frames of any size can be made from the hollow profiles 20 by using different lengths, the area of application is also very variable in this respect. However, it is also possible to make frames from the hollow profiles 20 with the corner connectors 30, which can even accommodate advertising or information materials as wall elements, such as bus timetables in bus shelters. The structural design described below does not change as a result. The external shape of the hollow profiles 20 can be designed in different ways. The hollow profiles are preferably extruded profiles made of aluminum. When used, especially as decorative profiles, they can also be made of plastic.

The hollow profile 20 is a closed profile body with a visible surface 22 and a base surface 23, which enclose a chamber 21. The visible surface 22 can have any shape. The base surface 23 is flat. Several grooves 24; 25; 26; 27 are arranged in it, which are preferably U-shaped. These lie against one another and are laterally delimited by webs.

DE7 86RÖ01 ; ; : : : · : :*··:.:

- 12 -

The grooves 24; 25 are open towards the chamber 21 and the grooves 26; 27 are open towards the base surface 23. Clamping elements are arranged on the closed front surfaces of the grooves 26 within the chamber 21. Furthermore, projections 29 protruding into the chamber 21 are arranged on the upper part of the visible surface 22 and on the closed front surface of the groove 28. The grooves 24; 25 as well as the clamping elements 28 and the projections 29 in the chamber 21 serve for plug-in connection with the corner connector 30. Visible elements such as information carriers, glass panes, but also a rear wall can be inserted into the grooves 26; 27 open towards the base surface 23.

Fig. 5 shows the corner connector 30 used to connect the hollow profiles 20. It is preferably made of plastic. Its cap 31 corresponds in its cross-section to that of the visible surface 22 of the hollow profiles 20. The corner connector 30 has two flat base surfaces 32 arranged at right angles to one another. With these, it rests on the front sides of the hollow profiles 20 to be connected. It is provided with plug-in elements 33; 34 which engage in the grooves 24; 25. The plug-in elements 34 are arranged on a base body 35 which gives the corner connector 30 the necessary stability and carries the cap 31. In this base body 35, a vertical slot 36 is provided which engages in the projections 29 of the hollow profile 20. This solution according to the invention ensures a firm connection of the hollow profiles 20 to form a rectangular frame. For this connection, as well as for the connection of frame 1, no screw or rivet connection is necessary. A permanent connection is achieved by gluing or caulking.

Another important feature of such a display case is a locking mechanism that prevents accidental opening, but at the same time also allows it to be opened easily. Such a locking mechanism is shown in Figs. 6 and 7.

The locking mechanism is located on the lower horizontal hollow profile 2 of the

Frame 1. It engages in the lower part of the frame of the folding door 3 and fixes it in the closed position. Two laterally arranged latches 40 are provided for this purpose, while a locking part 48 is arranged in the middle part of the display case and is accessible from below.

In the closed position, the latch 40 engages behind a bracket 42 arranged on the frame profile of the folding door 3. It is pressed upwards by a spring 43, preferably a leaf spring, arranged under the latch 40 and is thus held in the locking position. The folding door 3 is secured against unintentional opening.

The opening and closing mechanism has the locking part 48 shown in Fig. 7. This is mounted in a holder 52, which is attached to the lower hollow profile 2 of the frame 1. It is accessible from the underside of the display case. A pivot pin 49, which is preferably provided with a square at its lower end, is arranged vertically in the holder 52. A cross pin 50 is attached to the upper end of the pivot pin 49 at right angles to it. The cross pin 50 rests on a pin 47 attached to a shaft 45. The shaft 45 extends parallel to the lower hollow profile 2 of the frame 1. It is mounted in at least two bearings 46 so that it can rotate about its longitudinal axis. In the area of the bolts 40, which are pivotably mounted on an axis 41, a cam 44 is arranged on the shaft 45 for each bolt. To open the display case, the pivot pin 49 is turned using a key. The cross pin 50 then moves the pin 47 so that the shaft 45 is rotated about its longitudinal axis and the cams 44 swing downwards. They then press on the bolts 40 assigned to them. These swing downwards about their horizontal axis 41 against the force of the spring 43 and release the holder 42. The flap door 3 swings outwards, being held in its open position by the gas spring 5 (Fig. 1). When closing, the bolt 40, the front of which has an oblique

DE786RÖ01 ! ! I &idigr;

- 14 -

surface/ is gradually pressed downwards by the bracket 42 attached to the flap door 3. The rear end of the bolt 40 forms a vertical surface. When this point is reached, the bolt 40 is pressed upwards by the spring 43, and the bracket 42 slides behind the bolt 40 or behind its head. In this position, the flap door 3 rests against the seal 18 (Fig. 2), and the display case is closed.
