Description

The invention relates to a clamping device for flat Products and an associated holding device.

A combined clamping / holding device is from the DE 33 34 092 C2 known. It is there as a holding frame for designates and exists an image or similar fabric consisting of two holding steles and a spring part. The two Holding parts are pivotable relative to each other and consist of comparatively stiff extruded Plastic, one of the holding parts a holding section has the spring part for clamping holding the Fabric against the fabric and the one below it other holding part is pressed. The spring part is in one piece by an extrusion process on the two Molded holding parts and consists of a softer Material than the two holding parts.

A holding frame of the aforementioned type has fundamentally proven. The need to use different materials use, but is a disadvantage.

Accordingly, the invention is based on the object Holding frame of the aforementioned type so that it is made a material of a quality can be manufactured and manufacturing not on extrusion (extrusion) is limited.

The invention is based on the knowledge that this Aim through a constructive modification of the known Holding frame can be reached.

In its most general embodiment, the Invention a clamping device for flat Products with the characteristics of the main claim.

Such a clamping device can be a discrete component produce in any length and size.

Are holding part, bracket and Tilting part firmly connected to each other, so lets the clamping device as an injection molded part easily and Manufacture inexpensively from plastic.

With the holding part, the clamping device is opened, for example put on a plate. By lifting the bracket or tilting part becomes a distance between the tilting part and holding part created, for example, a picture to insert. When lifting the bracket respectively Tilting part, the bracket is put under tension. Will the Release bracket or tilting part again before the Tilting part its stable second position (release position) reached, the preload causes an automatic Return of the bracket (with attached tilting part), the inserted image between the tilting part and the holding part pinched and fixed.

The constructive design with two stable positions (Clamping position, release position) has the advantage that the Clamping device also in a static (open) Condition can be brought. A light tap the bracket towards the holding part causes the Bracket with the tilting part without great effort snaps back.

The pivot bearing and / or the joints of the tilting part can be trained in different ways. To In one embodiment, they are formed by zones that weakened compared to the neighboring sections are formed, i.e. a lower material thickness exhibit.

Based on the aforementioned application, the For example, the L-shaped bracket and the tilting part runs essentially parallel to the corresponding one in the clamped position Bracket part.

The swivel path of the tilting part and bracket is included different, due to the relative bending stiffness of the tilting part and its pivoting around the ends Joints in relation to the essentially elastic Bracket and its pivoting around the pivot bearing in the Connection area to the holding part.

The description of the figures below will be further Give hints.

For clamping the flat product between himself and the holding part is the tilting part after another Embodiment with a towards the holding part projecting section formed.

However, this is not absolutely necessary since the clamping device can also be used to hold a profile rail, which are placed or attached to the outside of the bracket becomes. In this case, the profile rail can be designed in this way be that they have the function to hold the flat product takes over, so in the clamped position protrudes further towards the holding part than the corresponding section of the tilting part. A corresponding embodiment is also in the Figure description shown and described.

Around the holding part on a frame or a plate to postpone it is, for example, "fork-shaped" designed, so essentially has a U-cross section on. In this case, for example, the one to be inserted Plate can be locked in the holding part when the holding part is on has a run-up slope on an inner surface. Corresponding the plate must have a corresponding opening, behind which the run-up slope then merges snaps into place.

The clamping device described can be rail-like designed (and is then, for example, with the help of a Extruders manufactured); but several can Clamping devices to a functional unit (Holding device) are put together, the Clamping devices then with each other by means of a Bracket of the clamping device attachable profile rail be connected to each other.

The particular value of this embodiment is that the profile rail made of any material can be. If it is made of aluminum, for example the holding device receives a special overall favorable appearance. The profile rail can be on the bracket attached or glued to them; any other too Connection technology is possible.

Further features of the invention result from the Characteristics of the subclaims and the other Registration documents.

The invention is based on a Embodiment explained in more detail.

The holding device shown in Figure 1 consists of a clamping device 10 and an attached Profile rail 12.

The clamping device 10 comprises a U-shaped section Holding part 14, the legs 14a, 14b of the holding part 14 record a plate 16 between them. To fix the Plate 16 in the holding part 14 is the inner surface of the leg 14b formed with a run-up slope 18, which in a corresponding opening 20 of the plate 16 in the engagement position shown engages positively.

From the connecting portion 14v of the holding part 14 extends first an arm 22 projecting vertically upwards, to which is followed by a tilting part 24 which in one end 26v of a bracket 26 merges, which is shown in the Clamping position essentially parallel to the tilting part 24 and Arm 22 runs at a distance from these and with its other End 26h materially connected to the connecting section 14v of the holding part 14 is connected.

At both ends of the tilting part 24 there are zones 28a, b, who are weakened in material (here: by corresponding slots). In this way, tilt joints trained, as will be described in more detail below.

Similarly, the end 26h of the bracket 26 is on the connecting portion 14v connected, this Area hereinafter referred to as pivot bearing 30.

The front portion 26v of the bracket 26 is as shown cranked (section 26a) and the bracket 26 has one along its L-shaped main portion Locking projection 26r. The cranked section 26a and Locking projection 26r serve to accommodate the above Profile rail 12, which consists of aluminum, the Profile rail 12 two clamping devices 10 of the above mentioned type, which are spaced apart on the plate 16 are arranged, connects together and so a total creates web-like holding device.

As shown in Figure 1, the front free end 12e is the Profile rail 12 on the leg 14a of the holding part 14 in the clamping position shown and can be used here Take a picture (not shown) as an example.

The user accesses the opening device Example behind the nose 12n of the rail 12 and moves this away from the holding part 14. During the normal Swing radius of the tilting part 24 around the joint 28b with R2 is shown, the normal swing radius of the bracket 26 around the pivot bearing 30 with R1. The one with "Ü" marked intersection of the radii R1 and R2 describes the degree of hardness (the preload) or the restoring torque of the bracket 26. The with "A" and "E" Points marked at the beginning define as Clamp position or release position mentioned End positions.

Figure 3 shows the clamping device 10 in said Release position.
