Definitions

  • the invention relates to a device for holding posters or the like, which has at least on two opposite sides a frame which consists of a lower profile part and an upper profile part pivotably arranged thereon.
  • Devices of this type which are often used as so-called stands, are known per se from US Pat. No. 3,310,901.
  • leaf springs are used between the upper and lower parts, which cause the upper part to be both in its closed position and is held in its open position by the force of the springs.
  • the insertion of a poster or the like. takes place in the open position of the upper part of the circumferentially arranged frame.
  • the edge areas of the poster are held by clamping forces exerted by the end faces of the upper parts on the lower parts. It proves disadvantageous here that the clamping force is not large enough to securely hold the posters or the like. to guarantee. Especially not when there are wind loads. In this case, the posters are torn out of their frames, which leads to premature destruction.
  • the invention is based on the object, while avoiding the aforementioned disadvantages, a device for holding posters or the like. to create the type mentioned, which is not only designed and easy to handle, but also a secure mounting of the clamped posters or the like. guarantee.
  • this is achieved in that the lower section and the upper section of the profile are equipped on their mutually facing inner sides with bearings in which the ends of two one-armed levers are pivotally mounted, which are connected to one another by means of a joint which has a bearing which is provided with a clamping claw assigned in its angular position to the underside of the lower part.
  • at least two such toggle levers are provided over the length of a frame leg.
  • two frame legs on two opposite sides are sufficient, but there is an optimal arrangement with four circumferentially arranged frame legs which complement each other to form a self-contained frame, the legs of which are mitred.
  • All parts of the device according to the invention are made of extruded material, which can be pushed into one another in the axial direction, so that assembly is very simple. Due to the clamping claw provided on the joint of the toggle lever, a force is exerted on the lower part when the upper part is closed, which force or the like lies between the edge area of a poster. clamped so that it is secured against unintentional loosening.
  • the bearing of the lower part is located at the free end of a projecting web, while that of the upper part is provided in the lower area of the front end face.
  • the length of the levers of the knee joint are dimensioned and their bearings are arranged such that when the upper part is closed, one corner region of the clamping claw first touches the underside of the lower part and then one until the upper part has reached the end position Performs swivel movement up to its horizontal position.
  • the swiveling movement tightens the poster in its end areas, while the clamping force is fully effective in the horizontal position of the clamping claws.
  • a tension spring is inserted with its two ends into the bearing of the lower part and that of the upper part at least on one side of a toggle lever. This prevents the toggle levers from slipping downwards when installed vertically.
  • the lower section 1 and the upper section 2 are aligned on their mutually facing inner sides with bearings 5, 6.
  • the correspondingly designed ends 7, 8 of two one-armed levers 9, 10 are arranged pivotably.
  • the levers 9, 10 are connected to one another by means of the joint 11, so that they form a toggle lever.
  • the bearing 5 of the lower part 1 is located at the free end of a projecting web 12, while the bearing 6 of the upper part 2 is located in the lower region of the front face 13 of the upper part 2.
  • the bearing 14 of the joint 11 is provided with a clamping claw 16 assigned to the underside 15 of the lower part 1 in its operative position.
  • the length of the levers 9, 10 is such and their bearings 5, 6, 11 are arranged such that when the upper part 2 is closed, one corner region of the clamping claw 16 first touches the underside 15 of the lower part 2 and then until it is reached the end position of the upper part 2, this performs a pivoting movement into its horizontal position.
  • the corner area of the clamping claw 16 sits on the poster.
  • the clamping claw 16 carries out a pivoting movement, the distance between the center axis of the end 7 of the lever 9 and the center axis of the end 8 of the lever 10 being greater by the amount of the elastic deformation than the design dimension between the center axes of the ends 7, 8 of the levers 9, 10 and the center axes of the joint 3 and the end 8.
  • a clamping force arises which is from Profile upper part 2 is passed through the bearing 3 in the profile lower part 1.
  • the closing pressure exerted on the upper section of the profile causes a supporting force in the corner region of the clamping claw 16, which counteracts the closing pressure and is introduced into the system via the joint 11 in the axial direction of the levers 9 and 10.
  • toggle lever system 5-11 Since the toggle lever system 5-11 generates the closing force only when the profile upper part 2 is closed, but remains de-energized in the open state, additional spring elements 18, 19 are provided, the ends of which are supported in the bearings 5, 6 of the lower part 1 and of the upper part 2, as can be seen in particular from FIG. 4.
  • the pivot points of the bearings 3, 5, 7 and 6, 8 are coordinated with one another in such a way that a spring which is clamped between the pivot points 5, 7 and 6, 8 generates a holding force both in the closed and in the opened state of the profile upper part 2 , which fixes the respective position.
  • the springs 18, 19 secure the toggle lever system 5-11 against slipping if the frame legs should be in a vertical position.
