HK1186513B - Slide plate for a cam-type closure - Google Patents

Abstract

The invention relates to a slide plate (20) for a cam-type closure of a clamping device for releasably connecting two profiled pieces (2), comprising a coupling region (11,28) for coupling to locking elements of the clamping device. The slide plate comprises an inner opening (23) for receiving an eccentric roll of the clamping device by which the axial displacement (30) of the slide plate (20) can be carried out. To this end, a spring region (27) is provided between the inner opening (23) for receiving an eccentric roll and the coupling region (11, 28). As a result of the resilient actuation of the eccentric roll, the user feels rising resistance, whereby haptic feedback is also provided. A closure element provided with such a slide plate additionally has a greater tolerance for profiled sections to be attached to each other.

Description

The Commission has also adopted a proposal for a directive on the protection of workers from risks related to exposure to ionising radiation.

The present invention relates to a sliding plate for an eccentric closure of a clamping device for soluble joining of two sections of a profile as defined in claim 1.

The Technical Standards

Such a slide is known from the applicant's WO 97/20148 A1. It is part of a clamping device for the soluble connection of two sections of a profile described therein. One of the insertion cores of the clamping device has an axially moving slide with an end to move a clamping element that can be inserted at least partially into an opening in one of the two sections of a profile. The slide has an inner opening to accommodate an eccentric roller with which the axial displacement is performed.

This clamping device works very satisfactorily and has no functional problems. However, it requires precise manufacture of the excess roller and its storage, and the slide plate and its opening to accommodate the excess roller, since the rotation of the excess roller in the opening acts on the plate and thus moves the clamping element.

The following shall be considered as a single product:

The present invention is based on the present state of the art and is intended to specify a sliding plate for a clamping element of the above type which allows easier clamping and is less sensitive to manufacturing tolerances.

This is achieved in accordance with the invention with a slide plate with the characteristics of claim 1 by proposing a slide plate for an eccentric closure of a clamping device for soluble connection of two profile pieces, having a coupling area for coupling to locking elements of the clamping device, with an internal opening for the reception of an eccentric valve of the clamping device, with which the axial displacement of the slide plate can be carried out, and a spring area between the increasing opening for the reception of an eccentric valve and the copper-plate area. The passing through of the eccentric valve is ensured by an unobtrusive contact between the two elements, so that a reverse rotation of the slide plate is not possible and a loss of a reverse rotation is not possible in the case of a simultaneous rotation of the slide plate.

The spring area consists of a single-piece design of the slide surface, which makes the part easy to manufacture and reliable for long cycles.

It is preferable to provide two lateral spring areas which terminate in an end area of the slide plate opposite the coupling area, which makes it possible to provide between the two lateral spring areas a counter-spring connected to the end area, which has the inner opening, so that a load on the edges of the inner opening with the tension force is well conducted through the eccenter.

Other embodiments are given in the dependent claims.

An essential advantage of the slide according to the invention for a clamping device is that the individual components, in particular the profile pieces in which the clamping devices are used, can have a greater play, i.e. can be manufactured with greater tolerances without loss of operational reliability.

The following is a brief description of the drawings:

The following illustrations, which are intended for illustrative purposes only and are not to be interpreted restrictively, describe preferred embodiments of the invention. Fig. 1 shows a partially cut side view of a clamping device with a slide according to an example of the invention;Fig. 2 shows the slide from Fig. 1 in a perspective view;Fig. 3 shows the slide from Fig. 1 in a side view;Fig. 4 shows a drawing view of the slide from Fig. 2 andFig. 5 an explosion view of the clamping device from Fig. 1.

The following shall be considered as a single unit of account:

Fig. 1 shows a partially cut cross-sectional view of a clamping device 1 for soluble connection of two profile pieces, of which one profile piece 2 is shown as a profile surrounding an insert and the second profile piece 3 as a front surface 3 running transversely to it with an opening or usually a nut running perpendicular to the drawing level. The first profile piece 2 is brought in for connection to the second profile piece 3, which has the said opening to accommodate the clips 4, 5 of the clamping device 1 with its noses 6, which can then be connected by spreading the clips 4, 5 behind the two profile pieces. The clips and noses are fixed in 506 A 607 0 2 A, as shown in the figure, so that they can be held in equal proportion to the profile piece 6 in the opposite direction.

The clamping device 1 also has a core 7 in which the pins 4 and 5 are fixed in a familiar way by means of a pin bolt 8.

The bellbolt 8 is connected to a perforated bolt 11 which is more clearly visible in Figures 2 and 3.

The slide plate itself is marked 20 in Figure 1 and the 90° transition area 21 to the hinged bolt 8 can be seen in the space behind this bolt 8.

The reference symbol 22 denotes the eccentric roller which intervenes and penetrates the exception 23 shown in Fig. 3. The eccentric roller 22 is then led from the input core 7 to the side so that by rotating the eccentric roller 22 the slide plate 20 in the input core 7 can be moved in its longitudinal direction. The shift of the slide plate 20 in the longitudinal direction indicated by the arrow 130 results in a shifting motion of the pins 4 and 5, with the pins 8 thus translating the motion in a splitting or closing of the pins 4, 5 and 6 in relation to the nose.

The slide plate 20 is placed in the centre of application 7, the translational movement in the direction 130 being caused by the rotation of the eccentric 8.

In the example shown, spring 24 is essentially a U-shaped metal plate, which is inserted from the side opposite the hinges 4 and 5 into a corresponding reception area 25 of the clamping element 1.

Fig. 2 shows a perspective view of the slide plate 20, Fig. 3 shows the slide plate 20 then in a side view. The arrow 30 indicates the translational movement of the slide plate 20 and in particular the coupling pin 11. The rotation of the coupling pin 11 with the hole 28 to take the crank shaft 8 by 90 degrees in the transition area 21 is known from the state of the art and a preferred embodiment to make the clamp element 1 flat, so that it can be used in thin profiles attached to a mostly longitudinal profile piece. In other configurations, the connected crank shaft 11 can also be in the same plane as the pin 20. It is also not necessary that a crank shaft is provided for when the crank is designed to be moved in the direction of the pin 20 and the main rotation is provided in the direction of the pin 20 and the crank shaft 20 is designed to be moved in the direction of the pin 30 and the crank shaft 20 is designed to be moved in the direction of the pin 30 and the crank shaft 20 is designed to be moved in the direction of the pin 30 and the crank shaft 20 is designed to be moved in the direction of the pin 30 and the crank shaft 20 is designed to be moved in the direction of the pin.

The state-of-the-art slide plate of WO 97/20148 A1 is made of a complete material, except for the 23 to accommodate the bell bolt 22.

The slide plate 20 according to the present invention is also unidirectionally designed, but has several sub-areas, which are advantageously produced by punching. Thus, a counter-zone 31 is released from the full material of the slide plate 20. In this case, in an advantageous but not necessarily necessary design, lateral breaks 32 are released against the double S-shaped areas 27. In the direction of the slide 11, the excess 23 is released to absorb the spin bolt 22. Between the edges 31 and the edges 33 of the slide 23 on the two opposite sides of the opposite edges, the slide 34 are only 20 of the material of the slide plate, but in total, in the case of 20 cross-sections, these can be brought into contact with the excess bolt 22 due to the excess of 20 cross-sections.

The end face 31 ends on the side opposite the face 11 in an end face 35 with a favourable wider design. The side surfaces 36 of this end face 35 together with the end faces 37 of the front face 38 may be placed sideways in the insertion core 7 and, where appropriate, also on their surfaces, the top face 17 and the bottom face 18. In other words, in the insertion core 7 there is a cavity to accommodate the slide face 20 which has an extension equal to the distance between the side edges 36 and 37.

In the end zone 35, the illustrated example of the design provides as an option a suspension hole 29 to allow the slide to be suspended after a finishing step, such as hardening or grinding.

As indicated above, on the two sides of the opposite side 31 there are double S-shaped spring areas 27 each. This double S-shape means that material in the manufacturing process is pushed out from the main plane of the slide plate 20 by molds. Preferably, the two double S-shapes are shaped in the same direction with respect to the main plane of the slide plate 20 but they can also be pushed out in the opposite direction.

In the case of the spring plate originally extruded individually, care is taken to ensure that, when the side sections 32 and the exception 23 are made, when the opposite edge 31 is separated at the surfaces 34, that on the side leading to the end section 38 to the spring, there is also a punch hole 39 next to the opening 23 to which the extruder roll 22 is attached.

Exception 23 has a curve 33 with a predetermined radius, a flat area 40 and an opposite curve with the same predetermined radius, where point 41 is called the transition area. Note that the radius passes from a part of the opposite edge 31 to a part in the area 38. The eccentric roller 22 has a diameter of transition. The shape of the eccentric roller 22 is clearly visible in Fig. 5.

The improved operation of this slide 20 in relation to the state of the art is due to the fact that when the eccentric roller 22 is inserted and rotated, it is supported on the wall 40 and, in particular, there is a spring 26 that pushes the slide 20 away from the arrow 30 towards the end zone 35. However, the slide 11 is in the crank bolt 8 translatorily connected to the core 7 so that, only by the translatory motion transmitted, the cranks 4 and 5 move backwards and the noses 6 spread towards the second non-represented profile. When the maximum spreading is reached, which naturally also depends on the depth of execution of the back-cut opening in the second profile, a translator is located in the crank bolt 22 but no further in the translator's rotation.

In the present invention, a further rotation of the eccentric roller 22 causes the opposite tongue 31 to be pushed further away towards the end area 35. This is possible because the two lateral spring areas 27 with their double S-design have a certain inherent predetermined spring path and can be stretched by the forces that occur. In other words, the opposite tongue 31 moves relative to the front area 38 of the slide plate, particularly translatively detectable at the partitions 34.

In particular, the springway formed by the lateral elements (sprung areas) 27 can ensure that the user will feel an increasing resistance on such a clamping element 1 with the slide plate 20 which begins when the first clamps 4, 5 are pulled before the noses 6 are opened and makes the pulling and locking of the clamping element 1 to the connection of the two profile pieces haptically perceptible.

The advantage is that the slide is made of spring steel.

Figure 5 shows an explosion view of the clamping device as shown in Figure 1, whereby only the essential elements more visible from Figures 1 to 4 are described and marked. The eccentric roller 22 is pushed through and into the eccentric bearing 123 in the centre of the core 7 by the eccentric bearing 122, whereby by supporting the eccentric 222 on the U-shaped opening of the spring tip 126 of the spring 24 the spring area around the spring is impressible and soluble.
