Definitions

• the invention relates to a clamping device for flat products and an associated holding device.
• a combined clamping / holding device is known from DE 33 34 092 C2.
• a holding frame for a picture or similar flat structure consists of two holding parts and a spring part.
• the two holding parts can be pivoted relative to one another and are made of comparatively rigid extruded plastic, one of the holding parts having a holding section which is pressed by the spring part for clamping the flat structure against the flat structure and the other holding part located underneath.
• the spring part is integrally formed on the two holding parts by an extrusion process and consists of a softer material than the two holding parts.
• a holding frame of the aforementioned type has basically proven itself. However, the need to use different materials is a disadvantage.
• the invention has for its object to design a holding frame of the aforementioned type so that it can be made of a material of a quality and the production is not limited to extrusion (extrusion).
• the invention is based on the knowledge that this goal can be achieved by constructively modifying the known holding frame.
• the invention then relates to a clamping device for flat products
• a holding part that can be attached to a frame or a plate
• the essentially flexurally stiff tilting part can be transferred over the end joints when the bracket is pivoted about the pivot bearing from a stable first position (clamping position) to a stable second position (release position) with parallel tensioning of the bracket or from the release position into the clamping position while releasing the tensioning of the bracket is.
• Such a clamping device can be produced as a discrete component of any length and size.
• the clamping device can be easily and inexpensively manufactured from plastic as an injection molded part.
• the clamping device With the holding part, the clamping device is pushed onto a plate, for example.
• a distance is created between the tilting part and the holding part, for example to insert an image.
• the bracket When lifting the bracket or tilting part, the bracket is placed under tension. If the bracket or tilting part is released again before the tilting part has reached its stable second position (release position), the pretensioning automatically returns the bracket (with the tilting part connected), whereby the inserted image is clamped and fixed between the tilting part and the holding part.
• the constructive design with two stable positions has the advantage that the clamping device can also be brought into a static (open) state.
• a light tap the bracket in the direction of the holding part causes the bracket with the tilting part to snap back without great effort.
• the pivot bearings and / or the joints of the tilting part can be designed in different ways. According to one embodiment, they are formed by zones which are weakened in relation to the adjacent sections, that is to say which have a lower material thickness.
• the bracket is, for example, L-shaped and the tilting part runs essentially parallel to the bracket in the clamping position.
• the pivoting path of the clamping part and bracket is different, due to the relative bending stiffness of the clamping part and its pivoting about the end joints in relation to the substantially elastic bracket and its pivoting about the pivot bearing in the connection area to the holding part.
• the tilting part is designed according to a further embodiment with a section projecting in the direction of the holding part.
• the clamping device can also serve to hold a profile rail, which is placed or attached to the outside of the bracket.
• the profile rail can be designed in such a way that it takes over the function of holding the flat product in a clamping manner, that is to say in the clamping position it projects further towards the holding part than the corresponding section of the clamping part.
• a corresponding embodiment is also shown and described in the description of the figures.
• the holding part In order to push the holding part onto a frame or a plate, it is, for example, “fork-shaped”, ie essentially has a U-cross section.
• the plate to be inserted can be locked in the holding part if the holding part has a run-up slope on an inner surface.
• the plate must have a corresponding opening, behind which the run-on slope then engages when it is brought together.
• the clamping device described can be designed like a rail (and is then produced, for example, with the aid of an extruder); however, several clamping devices can also be put together to form a functional unit (holding device), the clamping devices then being connected to one another by means of a profile rail which can be placed on the brackets of the clamping devices.
• the profile rail can be made from any material. If it is made of aluminum, for example, the holding device is given a special overall favorable appearance.
• the profile rail can be attached to the bracket or glued to them; any other connection technology is also possible.
• FIG. 1 a holding device according to the invention in association with a plate (in section),
• FIG. 2 the clamping device from FIG. 1 in the clamping position
• Figure 3 the clamping device of Figure 1 in the release position.
• the holding device shown in FIG. 1 consists of a clamping device 10 and an attached profile rail 12.
• the clamping device 10 comprises a U-shaped holding part 14, the legs 14a, 14b of the holding part 14 receiving a plate 16 between them.
• the inner surface of the leg 14b is formed with a run-up slope 18, which in a Corresponding opening 20 of the plate 16 engages positively in the illustrated locking position.
• zones 28a, b which are weakened in material (here: by means of corresponding slots). In this way, tilt joints are formed, as will be described in more detail below.
• the front section 26v of the bracket 26 is bent as shown (section 26a) and the bracket 26 has a latching projection 26r along its L-shaped main section.
• the cranked section 26a and the locking projection 26r serve to receive the aforementioned profile rail 12, which here consists of aluminum, the profile rail 12 connecting two clamping devices 10 of the aforementioned type, which are arranged at a distance from one another on the plate 16, and thus as a whole creates a web-like holding device.
• the front free end 12e of the profiled rail 12 lies on the leg 14a of the holding part 14 in the clamping position shown and can, for example, hold an image (not shown).
• the user reaches for example behind the nose 12n of the profile rail 12 and moves it away from the holding part 14.
• R1 normal swivel radius of the tilting part 24 around the joint 28b
• R2 normal swivel radius of the bracket 26 around the swivel bearing 30
• the overlap of the radii R1 and R2 marked with "Ü” describes the degree of hardness (the pretension) and the restoring moment of the bracket 26.
• the points marked with "A" and "E” define the end positions mentioned at the beginning as the clamping position or release position.
• Figure 3 shows the clamping device 10 in the release position mentioned.
