Definitions

  • the invention relates to a connection for frame profile strips of presentation devices, in particular picture frames or picture showcases, two frame profile strips each being braced against one another at their ends by means of resilient tensioning elements and wherein the frame profile strips have inwardly projecting legs for holding a plate-shaped object in a plane parallel to the main plane of the frame .
  • tensioning element is not part of the frame, but is formed from additional components, which are expensive on specially provided holding devices the frame profiles must be connected. Frequent actuation of the clamping device loosens the connection to the frame profile, so that an exactly closed parting line is then no longer guaranteed.
  • the invention has for its object to simplify the exchange of pictures in picture frames and frameless picture carriers, especially in wall-anchored picture frames, which previously had to be dismantled to change the picture.
  • connection can be released or tensioned without removing or actuating any screws, clamps, brackets, toggle locks or the like.
  • connection according to the invention holds the frame profile strips both in the closed position and in an open position and is therefore also referred to below as a bistable spring tensioning element.
  • the connection according to the invention can be arranged on two or more end joints. In the case of a removable frame equipped with the connection according to the invention, an image exchange is possible from the front without the frame having to be removed from the wall. The same advantage arises with picture showcases or other presentation facilities.
  • the device according to the invention is suitable for round as well as for square frames or showcases with three, four or more corners.
  • the frame profile strips to be connected are preferably, but not exclusively, mitred and consist of extruded aluminum, plastic or wood.
  • the process of exchanging images is as follows:
  • the frame is placed with the back on a flat surface, by pressing on a frame leg towards the outside of the frame, the frame opens at the parting lines.
  • the image can be exchanged from the front.
  • the joint is open, the top of the profile projection on top serves as a support surface for the objects to be replaced.
  • the separating joints are closed by pressing the outside of the frame towards the center of the frame.
  • opening or closing the pressure initially increases due to the pressurization of the energy accumulator until the energy accumulator snaps into the other end position after a maximum force has been exceeded. At least in the closed position, the joints are held under a prestress.
  • bistable spring tensioning element is part of the frame and consists of components such as profile strip, guide part, energy accumulator and connecting pin - ideally only from the usual components such as the version consisting of frame profile, picture frame rear wall and connecting pin.
  • the guide part, the setting recess and the energy storage are formed by or from the picture frame rear wall according to claim 4 and 6.
  • the guide part is a flat angle, which has a closed slot recess at least in one leg side.
  • the guide part additionally has a wall fastening device which is designed such that there is a distance between the guide part and the wall exists to ensure the function of the movable frame parts.
  • the guide part is formed from the rear frame of the picture frame and has at least two closed setting recesses.
  • the guide part according to claims 2, 3 and 4 can be made of metal, plastic or other materials.
  • the energy accumulator is a compression spring, which is formed from an arc shape or a combination of arc and spiral shape, the design and arrangement in the setting recess is apparent from claims 5, 6 and 7.
  • the compression spring consists of a combination of arc and spiral shape, this increases the size of the energy accumulator with the same dimensioning of the slot recess.
  • the spiral section enables a kind of axial movement in the abutment, which supports the regulated sequence of the snap movement. With this arrangement, it is possible to store energy 8 and guide part 6 from the same workpiece, eg. b. Injection molding plastic.
  • the backdrop path arranged in the backdrop recess which represents the connection between the two energy storage end positions, runs in conformity with the opening direction of the parting line. The exact course is apparent from claims 8, 9, 10, 11 and 12.
  • a particular advantage of frameless picture carriers is that only parts of a profile strip are required for the holding function of the glass pane and picture, as is evident from the claim.
  • the guide space which is important for a closing and opening movement parallel to the main plane of the frame is formed from two profile projections and can be open at the projection ends or closed by a web.
  • the guide part is a plate-shaped fastening device with a front and rear arranged recess for receiving the profiled strip section according to claim 16. This design makes the guide part movable to the wall and also, for. B. a mirror back surface guaranteed.
  • FIG. 1 shows a perspective view of a frame corner which forms a bistable spring tensioning element 9. 4
  • two frame profile strips 1 are connected to one another, one profile strip being firmly connected to the associated angle leg by means of glue, rivets or compression, while the other angle leg is part of a bistable spring tensioning element 9 .
  • the parting line is open in the diagonal direction and has a parallel guide to the main plane, also called the image plane.
  • An energy store 8 according to FIG. 21 is located in the slot recess 7.
  • a connecting pin 13 is also shown.
  • FIG. 2 shows a frame corner which forms a bistable spring tensioning element 9, which represents a variant of FIG. 1. It is formed from the profile bar 27 and a flat angle with one-sided link recess according to FIG. 7.
  • the parting line 10 has a parallel opening of the movable frame bar.
  • FIG. 3 The picture frame rear wall as a guide part 6 is shown in FIG. 3.
  • the scenery path 16 runs according to claim 11.
  • FIG. 17 shows the front view of such a frame with four open parting lines 10.
  • the flat angle as the guide part 6 in FIG. 5 shows a device for the wall fastening 14, which is provided with a bore 26.
  • the two legs of the flat angle each have a link recess 7, in which the link path 16 runs diagonally to the movable frame strips.
  • Fig. 6 shows a backdrop recess 7, the backdrop path 16 installed in the frame has a diagonal course to the movable frame strips. Only in the closed position 15a is the energy store 8 in a locking section, the section 17, which has a parallel profile to the horizontal frame strips. This configuration of the setting recess 7 ensures that the closed frame corner does not open by itself due to the weight of the plate-shaped object 4 or other vertical tensile forces.
  • the sliding path 16 shows, installed in the frame, a parallel guide to the movable frame strips, as can be seen from FIG. 2.
  • the pressure spring can be selected so that a maximum of pretension in the closed position is opposed to a minimum of force in the displacement movement. This makes it possible to keep frame corners closed under load even without the locking section 17 shown in FIG. 6.
  • the slide path 16 shown in FIGS. 6, 7 and 8 can be arranged in the frame in all angular degrees depending on the arrangement of the parting line 10.
  • the setting recess 7 is then aligned so that the setting path 16 points in the desired opening direction of the parting line.
  • the energy store 8 according to FIGS. 21, 23 and 25 and the slot recess according to FIGS. 6, 7 and 8 represent the core of the bistable spring tensioning element 9.
  • An energy store inserted into the link recess, with seat from end 23a in one of the two end positions 15a or 15b and the other end 23b or 25 in abutment 19 is guided along end member 16 when end 23a is moved and is thereby reduced in distance pressurized to abutment 19. After exceeding the minimum distance, end 23a then snaps into the other end point.
  • the plate-shaped object 4 can also consist of a glass pane, picture and possibly also a picture frame rear wall and is located between the profile projections 2 and 5. Therefore this space is also called Denoted image chamber 20.
  • the frame profile 21 in FIG. 10 has two picture chambers 20, the glass pane being in the front and the picture with the picture frame rear wall in the rear. With this arrangement, plastic pictures or flat exhibits, such as. B. coins or the like are presented.
  • the 11 has the frame profile 27 with a closed guide space 12.
  • the two profile projections 2 and 3 are connected at the end by the web 22.
  • the setting recess 7 according to FIG. 7 is used, in which the setting path 16 is in a parallel course to the movable frame strip according to FIG. 2.
  • FIG. 12 shows a variant of a frame profile with a closed guide space 12 and two image chambers 20.
  • a frame profile 30 made of wood is shown.
  • the profile projection 5 is provided with a semicircular profile.
  • FIGS. 14 to 16 show frames with two diagonally arranged parting lines 10, which are in an open state.
  • FIG. 17 shows a frame with four opened parting lines 10.
  • the opening direction is at right angles to the movable frame strips.
  • the guide part 6 is formed by the picture frame rear wall according to FIG. 3.
  • a section of a profiled strip 1, which is designed according to FIG. 19, is located in a parallel opening to the picture frame rear wall, which functions as a guide part 6.
  • the link path 16 has a right angle to the outer edge 32 of the guide part.
  • 20 shows a wall fastening which is designed as a guide part 6 and has a depression 33 which is provided for receiving the holder.
  • 19 consists of a section of the frame profile 1 and is connected by means of a connecting pin 13 to the wall fastening.
  • the wall attachment is made by the hole 35 fastened to the wall by means of screws.
  • the energy accumulator 8 is a compression spring with two eyelet-shaped ends 23a and 23b and an arcuate central part 24.
  • the central part 24 bends more and thereby absorbs forces which, after exceeding the maximum force, return to the predetermined preload to be led back.
  • FIGS. 22 and 24 show frame corners with closed parting lines 10 and two alternative energy stores 8.
  • FIG. 23 shows an energy accumulator 8, which consists of the same workpiece as the guide part 6, which protrudes from the abutment 19 in a spiral shape 25 and which swings at the end of the abutment 19 into an oppositely arranged arc shape 24, in order to end in one Eyelet shape 23a to end.
  • the force accumulator 8 according to FIG. 25 is identical to the embodiment in FIG. 23.
