Abstract: A connecting element for mechanically connecting at least two components has a closure head for abutment against a first component and having a closure foot for abutment against a second component and for bracing the latter against the first component in a rotated final-mounting position. A stem portion extends between the closure head and the closure foot, which is spaced apart axially from the closure head in the longitudinal direction of the stem. The closure head has a sealing surface that extends in the longitudinal direction of the stem portion and sealingly abuts against a corresponding sealing surface of a recess in the first component. There is also described a connecting arrangement with a first component and at least one second component and a corresponding connecting element. The latter may be made from a single material component.

Abstract: A transmission device comprises an output element and a drive element comprising a drive body made from a first material, from a plastic. The drive body comprises a drive region and a connecting region. The output element engages into the connecting region that comprises positively locking structures which transmit a torque to the output element, the connecting region is configured such that the positively locking structures are radially movable, resulting that the output element is rotatable relative to the drive body with widening of the connecting region. The drive element comprises a compression element which preloads the drive body inwards in the radial direction in the connecting region, wherein the compression element is formed from a second material different from the first material and is elastic in the region of the widening portion and has a higher spring stiffness than the connecting region of the drive body.

Abstract: A switch arrangement for the selection of joining elements, which comprises a switch that comprises at least three supply points in which joining elements can be supplied to the switch in a position-oriented manner. Furthermore, an output point is provided where joining elements can be output in a position-oriented manner, the switch comprising a conveying element which has at least three receiving compartments each being adapted to receive a supplied joining element each at the supply point. A conveying element can convey the joining elements from a receiving position to an output position from the supply point to an output point, which is fixed relative to the supply points, and output.

Abstract: The invention relates to a connecting element (10, 20, 30, 50) for producing a component connection (70) of two components (72, 74; 92) lying against each other by means of the connecting element (10, 20, 30, 50), which is welded to the lower layer (74)—the base layer—by friction, wherein the connecting element (10, 20, 30, 50) has a shaft (18), which has a shaft segment (14) and a head (12) having a flat surface (20) lying on the top side of the head for transmitting the axial force, wherein a drive cutout (22, 32) is introduced into the flat surface (20) in order to transmit a torque.

Abstract: The invention relates to a switch arrangement (10, 40) for the selection of joining elements (30), which comprises a switch (14, 42) that comprises at least three supply points (12a, . . . f, 44a, . . . f) in which joining elements (30) can be supplied to the switch (14, 42) in a position-oriented manner. Furthermore, an output point (22, 66) is provided where joining elements (30) can be output in a position-oriented manner, said switch (14, 42) comprising a conveying element (18, 52) which has at least three receiving compartments (20a, . . . f, 56a, . . . f) each being adapted to receive a supplied joining element (30) each at the supply point (12a, . . f, 44a . . . f). A conveying element (18, 52) can convey the joining elements from a receiving position to an output position from the supply point (12a, . . . f, 44a, . . . f) to an output point (22, 66), which is fixed relative to the supply points (12a, . . . f, 44a, . . . f), and output.

Abstract: The invention relates to a rotary hopper feeder (10) for conveying and separating elements (20) which have at least one shaft, comprising a rotary feeder (18) with radially oriented conveyor cells (22) for conveying the elements (20), said rotary feeder (18) being at least partially surrounded by a hopper wall (14). The invention is characterized in that said conveyor cells (22) have holes (23) at the cell edges (18) and below the rotary feeders (18), near the holes (23), a rolling surface (28) is provided on which at least parts of the shafts of the elements (20) with shafts are supported and made to roll as they are conveyed.

Abstract: A tool for installing decorative lights may include a hook-placement head configured for attachment to a pole, and a string-placement head configured for attachment to the pole. The tool may be employed to decorate a structure with a string of decorative lights by placing an adhesive-backed hook onto a pole-mounted hook-placement head, raising the hook-placement head to position the hook at a desired location on the structure, placing a portion of the string onto a pole-mounted string-placement head; and raising the string-placement head to the positioned hook to engage the string with the hook.
