Definitions

• the invention relates to a frame for receiving posters or the like. with a base frame, at the edges of which front elements are fastened, each of which is connected to the base frame via a joint and can be individually folded out of the frame surface, each of the joints having a joint shell and a joint pin which can be inserted into the joint shell.
• Such a frame is known for example from DE-OS 31 32 521.
• the front elements of this frame are provided on the inside with a longitudinal groove into which an edge of a leaf spring engages, the other edge of which protrudes into a groove in the base frame.
• Several leaf springs are distributed over the length of the front element. When the front element is pivoted, the slightly curved leaf spring is tilted past its dead center, so that it holds the front element in a stable manner both in the closed position and in the extended position.
• the present invention has for its object to reduce the manufacturing and assembly costs of a frame of the aforementioned type, and to increase its stability significantly.
• This object is achieved in a generic frame in that the joint shell and the hinge pin are each formed on a profile element, wherein one of the profile elements has a locking element which engages the other profile element on an essentially circular arc-shaped surface in which at least one locking recess is trained.
• the frame according to the invention does not require leaf springs.
• the latching elements each of which engages elastically on a friction surface, in conjunction with the associated latching depressions, ensure that the front elements are held firmly in the closed or folded-out position even without leaf springs.
• the elimination of the leaf springs results in lower manufacturing and assembly costs.
• a preferred embodiment of the frame is that the locking element is designed in the form of an arcuate longitudinal leg on the profile element having the hinge pin.
• the hinge pin is provided with a longitudinal groove which defines two elastic leg sections. Due to its elastic leg sections, the hinge pin can be compressed by a certain amount when it is inserted into the hinge shell. This makes it possible to increase the circumferential area of the hinge pin which is encompassed by the hinge shell.
• a particularly secure connection of the hinge pin and the joint shell results in the aforementioned embodiment if the longitudinal groove of the hinge pin has an extension into which a round rod can be inserted in a form-fitting manner.
• You can do this on the inside of the Leg sections of the hinge pin are preferably formed at least three elevations with an acute angle in cross section, which are evenly distributed on the inner circumference of the leg sections.
• the acute-angled elevations make it easier to insert the round bar into the hinge pin by largely reducing the contact area and thus the friction between the round bar and hinge pin.
• Another advantageous embodiment of the frame according to the invention is that its front elements are releasably attachable to the respective pivotable profile elements. This makes it possible to provide the frame with differently designed front elements in color and / or shape, so that it can be optimally adapted to the particular installation environment.
• an expedient embodiment of the frame according to the invention is that the front elements and / or the profile elements are expediently lockable against unauthorized opening of the frame.
• Figure 1 is a cross-sectional view of a
• FIG. 1 Section of a frame according to the invention with a closed front element;

• the frame according to the invention consists of a base frame which is composed of four side parts, two side parts each being arranged essentially parallel to one another.
• the lower side part comprises a rectangular tube 1 and a square tube 2, which are connected to one another with an angular profile 3.
• the rectangular tube 1 forms with the square tube 2 a shoulder on which a hat profile 4 is fastened, which is flush with the square tube 2.
• the square tube 2 and the hat profile 4 carry a plate 5, which forms a border with the angle profile 3 for receiving posters or the like.
• the angle profile 3 also serves as protection against soiling from dripping poster glue (so-called glue channel).
• a double-angled profile element 6 is fastened to the outside of the angle profile 3, to which a front element 8 is articulated via a second profile element 7.
• the joint consists of a channel-shaped joint shell 9, in which a hinge pin 10 engages, which is provided with a longitudinal groove 11, which forms two elastic leg sections 12, 13.
• the longitudinal groove 11 has an extension 14, on the inside of which protrude three acute-angled ribs 15, which engage evenly distributed on the outer circumference of a round rod 16 inserted in the longitudinal groove 11 with a positive fit.
• An arcuate longitudinal leg 17 is formed in one piece on the profile element 7, which acts as a locking element and elastically engages on the joint shell 9 of the profile element 6 on a substantially circular arcuate friction surface 18.
• the friction surface 18 has a recess 19 into which the longitudinal leg 17 of the profile element 7, which is provided with an elevation, engages when the front element 8 is folded out (cf. FIG. 2).
• the front elements 8 can be secured against unauthorized opening by a suitable lock (not shown), which e.g. in the form of a lock or a flap that can be swiveled with a special tool, which in the closed position engages behind a projection on the base frame.
• a suitable lock e.g. in the form of a lock or a flap that can be swiveled with a special tool, which in the closed position engages behind a projection on the base frame.
• the profile element 7 has an essentially flat support surface 20, on which the front element 8 bears with a correspondingly flat wall section 21.
• the front element 8 is a hollow body which is stiffened on the inside by a plurality of cross struts.
• the profile element 7 is provided with a bead-shaped longitudinal edge 22 which is encompassed by a groove 23 of the front element 8.
• the profile element 7 is provided with an undercut longitudinal groove 24, into which 8 fastening elements (not shown) can be detachably anchored for fastening the associated front element.
• the front elements 8 are connected to one another by corner pieces (not shown).
• the front elements 8 and profile elements 6, 7 can also be mitred in the frame corners.
• the profile elements 6, 7 are preferably continuously cast from an Al-Mg-Si alloy.
• the front elements 8, however, are preferably made of plastic, so that different color and shape variants can be realized inexpensively.
