Definitions

the invention relates to a clamping device for items to be clamped, such as sheet stacks, display boards, maps, calendars or the like. with two clamping legs connected to one another via a back, one of which consists of two sections which are connected to one another at a distance from the back by a joint running parallel to the back, and of which the section connected to the part of the joint facing away from the back acts as an operating handle is formed and provided with a clamping stamp which can be pivoted from a position in which it faces away from the back and releases the material to be clamped into a clamping position in which it faces the back and one defined by at least one stop relative to the other clamping leg In the latching position, it rests resiliently against the material to be clamped or the other clamping leg forming a piece with the back.
a clamping device of the type under consideration made of plastic in which the clamping stamp is formed by a straight web.
the straight shape of the web means that the uppermost sheets of a stack of sheets are pressed against the back of the clamping device by the web and undesirable folds can form in the process.
a tongue protruding from the back between the clamping legs is used in the known device, which comes to rest during the clamping process between the stack of sheets and the clamping stamp and which prevents direct frictional engagement between the clamping stamp and stack of sheets.
the invention has for its object to design a generic clamping device such that it reduces the risk of wrinkling in the region of the edges of the sheets of a stack of sheets facing the back of the clamping device at least significantly and even if there is no tongue protruding into the clamping gap and that it is above it furthermore, regardless of the presence or absence of the tongue, the clamping of the clamped material is facilitated.
This object is achieved in that the free end of the clamping plunger is designed as an arc-shaped skid which rolls on the material to be clamped during the clamping process.
the device according to the invention has the advantage that the contact surface between the clamping stamp and the sheet material is comparatively large due to the skid-like design of the clamping stamp during the clamping process, the surface pressure between the stamp and the clamping material is consequently reduced and the risk of wrinkling of sheets of a sheet material stack is therefore largely excluded is.
the clamping device according to Figures 1 to 5 has two clamping legs 1 and 2 and a back 3.
the clamping leg 1 is divided into two sections 1a and 1b, which are connected to one another via a first joint 4.
a second joint 5 connects section 1a of the clamping leg 1 to the back 3 of the clamping device.
a web made of elastic material which forms a spring 6 which, in conjunction with the second joint 5, serves the clamping capacity of the clamping device both with respect to the thickness of the material to be clamped and with respect to to improve durability.
the clamping material 7 to be recorded which is regularly formed by a stack of sheets, is clamped between the clamping leg 2 and a clamping stamp 8, the latching position of which relative to the clamping leg 2 is determined by a stop 9.
the clamping punch 8 and the stop 9 are formed by webs, the arrangement of which is such that the Distance A between the back 3 of the clamping device and the connection point of the first joint 4 with the section 1b of the clamping leg 1 in the latching position is greater than the smallest distance a between the back 3 and the point at which the free end of the clamping stamp 8 is open the clamping leg 2 or the material to be clamped 7 (see FIG. 6).
the clamping device When the material to be clamped is introduced into the clamping gap 10, the clamping device assumes the position shown in FIG. From this position, the section 1b of the clamping leg 1 is pivoted clockwise, as shown in Figures 2 to 5. During the pivoting process, the free end of the clamping stamp 8, which is designed as an arc-shaped sliding skid 11, moves over the stack of sheet material into the clamping position shown in FIG. At the same time, the stop 9 comes to rest against the stack of sheets. Due to the inherent elasticity of the clamping legs 1 and 2 consisting of a hard PVC and the back 3 and due to the spring action of the spring 6 made of a permanently elastic plastic, the guarantee for a perfect clamping effect is given.
FIGS. 6, 7 and 8 show slightly modified clamping devices, the same reference numerals being used for the corresponding parts as in the previously described embodiment and only the differences will be discussed below.
FIG. 6 shows a clamping device with a spring 13, which is additionally connected to the back via a bracket 14.
the clamping leg 2 is provided on its inside with a non-slip pad 15 in this embodiment.
a compression spring 17 is used to support the clamping force in addition to a tension spring 16, both springs being connected to the back 3 over the entire surface. It has proven to be particularly advantageous that the end of the clamping plunger 8 facing the glenk 4 forms a support 18 in the clamping position for supporting the end of the section 1a of the clamping leg 1 connected to the back 3 that is remote from the back.
the clamping leg 2 is provided with an adhesive layer 20 covered by a peel-off film 19, which, for example, enables the clamping device to be easily attached to a writing board (not shown).
FIG. 8 finally shows a clamping device, in which a guide tongue 22 with a latching cam 23, which is under the action of a return spring 21, is arranged between the clamping punch 8 and the clamping leg 2.
This locking cam 23 must be overcome when opening the clamping device and consequently represents an additional locking of the clamping device in the clamping position.
the clamping device shown in the figures can be produced in a highly economical manner. It is indeed possible not only the clamping legs 1 and 2 and the back 3, but at the same time also form the joints 4 and 5 and the springs 6, 13, 16, 17 and 21 and the guide tongue 22 as a coextrusion profile and to obtain individual clamping devices from the profile produced by separating them.
