Abstract:
The invention relates to a clamping and/or emergency braking device (30) to be mounted on a carriage (20) that is guided by means of at least one guide rail (10), said guide rail having at least one engaging contour (15). The device comprises at least one frictional locking mechanism having at least one friction shoe (120) that can be pressed against the guide rail against the effective direction of the retaining force (19) of the engaging contour. The frictional locking mechanism can be displaced in one direction by means of the elastic force of at least one spring element (122, 123) and can be displaced in the opposite direction by means of a feed force, generated by a drive (60). At least one single-stage drive mechanism (70) is interposed between the drive (60) producing the clamping force and the friction shoe. The invention provides a braking and/or clamping device that produces a strong clamping force, has a simple design, requires little installation space and is permanently maintenance-free.

The invention relates to a combined acceleration and deceleration device comprising: a follower element that is guided, in a supporting and guiding device, between a force-fittingly and/or form-fittingly secured park position, and an end position, said follower element comprising at least two follower stops; an energy store arranged on the supporting and guiding device and on the follower element, which store can be charged and discharged repeatedly, being charged when the follower element is positioned in the park position and discharged when the follower element is positioned in the end position; and an actuation element of the deceleration device, connected to the follower element; as well as a system with a tractive and braking device pair. The follower element comprises a guiding part and a securing part which is connected to, and can be pivoted in relation to, said guiding part. The guiding part and the securing part each have at least one follower stop. The energy store is arranged on the securing part, and the actuation element of the deceleration device is arranged on the guiding part. The invention allows the play of an acceleration and deceleration device to be reduced when in use.

The invention relates to a dowel for fastening to planar components (100) having a first (101) and a second (111) cover panel and at least one intermediate support core layer (121), wherein the dowel comprises at least one expansion body (10) (which accommodates at least one fastening means) and at least one wedge body (60) guided in the expansion body. The placed dowel fits in a cutout (130) which passes virtually right through the planar component. The placed dowel engages behind the first cover panel by way of at least one rear-engagement element (42). At least two dowel-side clamping elements bear in a radially clamped manner in the lower region of the cutout. The dowel has at least one cavity (49, 59) - for accommodating a relatively large number of adhesive-containing balloons (3, 4) - with at least one opening (43, 53), wherein the maximum width of the individual opening is smaller than the diameter of the smallest balloon. The dowel developed with the present invention is one which, apart from being simple to mount, holds firmly, securely and permanently in the lightweight building panel.
Abstract:
The invention relates to a braking and/or clamping device of a shaft that is mounted in an equipment housing or the device housing. Said device comprises a brake disc that is rotationally fixed on or to the shaft and a clamping ring that is mounted in the device housing. The brake disc has a friction region comprising two friction surfaces covering truncated cones. The device has at least one brake cone that is situated in the device housing and at least one brake cone that is located on an actuator. During the braking or clamping procedure, one brake cone is applied to the brake disc, whilst the other cone is applied to the clamping ring. The brake disc and the clamping ring make contact with one another between these application points. The invention permits the development of a braking and/or clamping device for rotating shafts that has a simple compact construction, producing strong clamping forces with short reaction times and that in addition is not prone to malfunction and requires no maintenance over its service life.
Abstract:
The invention relates to a valve with a magnetic or magnetisable pilot valve body and a main valve body for a vacuum System in a wood processing machine, whereby the wood processing machine comprises a clamping table running in at least one vacuum zone, with at least one drilling for mounting the valve such as to sit below the clamping table surface, between the vacuum supply Channels and the clamping table surface, whereby a suction adapter supporting the workpiece is arranged on or in the clamping table, which, on the side thereof facing the clamping table surface, is at least partly made from a material, or has a device, which opens the valve, closed in the idle State, by a magnetic interaction and hence sucks the suction adapter to the clamping table and/or the workpiece to the suction adapter. According to the invention, a valve is developed, permitting an opening with applied vacuum, which rapidly closes on unexpected pressure rise and which guarantees a secure functioning in all operating conditions.
Abstract:
The invention relates to a device in which a movably mounted output element (106) has two end positions, wherein a latching mechanism (50) is arranged between the output element and the driving device thereof, via which latching mechanism the output element can be brought by a lifting or pivoting movement during a first driving pulse out of the first into the second end position counter to a restoring force and via which, during a second driving pulse, the output element can be transferred from the second into the first end position by the restoring force. A device is developed by the present invention, the device, for example within a braking, clamping or gripping device, permitting two stable end positions in which the particular useful device is kept in the actuated or unactuated state without the supply of external power.
