摘要： The frame of the pushchair has two parallel struts (12) for the front wheels and two parallel struts (14) for the rear wheels and with a hinged coupling stabilised by folding side struts (18). The hand grips (72) are on parallel sliding supports which slide downwards after the securing catch is released, to form a compact unit. The bottom ends of the sliding supports (16) extend down to beside the front wheels, to from ground supports beside the wheels. The collapsed frame can be stood up on the front wheels and the collapsed struts, to form a stable storage position. The same securing catch holds the unit in the collapsed state as it does in the errected state. ADVANTAGE - Simple to operate, stable storage position.

摘要： A frame for a child's or doll's pushchair having two armrest frames (2) which are connected to one another by bolts (4) which form the base of the frame and which lie laterally one opposite the other, and having a backrest frame (6) and a foot support frame is described, the backrest frame (6) and the foot support frame being swivellable onto the lateral armrest frame (2) and being lockable with respect to the base of the frame in various angular positions. In order to lock the backrest frame (6), a catch plate (8) is mounted on each armrest frame (2), the said catch plates (8) being connected by means of an axle (10) about which the backrest frame (6) can be swivelled. Each of the two catch plates (8) has a number of recesses (12) which are arranged concentrically with respect to the axle (10) and into which counter-catch elements (14) which are parallel to the axle (10) can be engaged in order to lock the backrest frame (6). The counter-catch elements (14) are attached to the axle (10) and the axle (10) is constructed so as to be laterally displaceable in its longitudinal direction between two limit positions.

摘要： A disc wheel which consists of two metal discs (1) which are connected in mirror-inverted fashion next to one another and to one another, have a finished surface and are shaped at their circumference in such a way that they are suitable for positioning a rubber tyre (4). In this arrangement, the two metal discs (1) have on their circumference a flange (2) which runs perpendicular to the axle (5) of the wheel and at which the two discs (1) are connected to one another. The rubber tyre (4) has on the interior of its outer surface (41) which is matched to the shoulders (11) of the two discs (1) a radial circumferential slot (44) with which it is positioned on the common flange (2). As a result, the processing and connecting points (10) of the two metal discs (1), which are preferably spot weld points, are not externally visible so that sheet metal which is already surface-finished can be used as the starting material for manufacturing the disc wheels and subsequent working of the metal discs (1) is dispensed with.

摘要： A description is given of a spacing device (36) for preventing direct contact between an end portion (34) of a first frame element (20) of a pram frame (12) and a second frame element (22) of the pram frame (12), which second frame element is connected pivotably to the first frame element (20). The spacing device (36) has a first bearing surface (38) bearing against the end portion (34) of the first frame element (20) and a second bearing surface (40), facing away from the first bearing surface (38), for the second frame element (22). Provided on that end portion of the spacing device (36) which faces the end of the first frame element (20) is a cap element (42) which is designed in one piece on the spacing device (36) and protrudes over the first bearing surface (38). The cap element (42) is fixed on the end portion (34) of the first frame element (20). The one-piece design of the spacing device (36) with the bearing surfaces (38, 40) and with the cap element (42) not only safeguards the two frame elements (20, 22) against inadvertently making contact with each other but also, at the same time, seals off the one frame element (20).

摘要： A description is given of a storm bar (14) for a hood (12) of a pram/push-chair, which has two bar elements (16, 18) and a connecting spindle (20) connecting the bar elements (16, 18) to each other. The two bar elements (16, 18) can be pivoted around this connecting spindle (20). The storm bar (14) has a housing with a housing lower part (26) and a cover (42), one bar element (16) being fastened by its joint-side end section (22) in the housing lower part (26) which is designed with an arcuate element (28) arranged concentrically to the connecting spindle (20). The arcuate element (28) is of resilient design with latching recesses (30) which are arranged concentrically to the connecting spindle (20). The second bar element (18) projects by its joint-side end section (32) into one of the latching recesses (30). The housing (26, 42) covers the joint-side end sections (22, 32) of the two bar elements (16, 18) in every angular position thereof so that the risk of injury by the bar elements (16, 18) is ruled out.

摘要： A description is given of a pushchair frame with a suspension device (36) provided for a wheel axle (42) and arranged between a frame element (10) of the pushchair frame and a pivoting arm (18). The pivoting arm (18) is mounted on the frame element (10) of the pushchair frame in a manner such that it can pivot about a spindle (16) which is aligned parallel to the wheel axle (42). In the region between the spindle (16) and the wheel axle (42), the pivoting arm (18) has two cross-arms (20) pointing in opposite directions, each cross-arm (20) being constructed with a holding part (22) at its outer end. Arranged between the two holding parts (22), projecting away in the same direction from the pivoting arm (18), and the associated frame element (10) of the pushchair frame is a spring element (36) which can be subjected to compression. By virtue of this design of the pushchair frame, between the wheel axle (42) and the frame element (10) of the pushchair frame it is possible for a reciprocating movement about the spindle (16) to take place, which movement is resiliently damped by the two compression spring elements.

摘要： A description is given of a device for the releasable connection of a pram/push-chair body to a pram/push-chair frame, which device has a sprung locking member (22), an actuating element (34) which can be adjusted between two positions, and a recess (28) for receiving a latching element. In the first position of the actuating element (34) the locking member (22) adopts the locking position and in the second position adopts the release position. After an actuation the actuating element (34) is fastened in its second position by means of the locking member (22), the locking member (22) adopting an intermediate position between the locking and the release positions. By removing the latching element (14) from the recess (28) the locking member (22) is adjusted from the intermediate position into the release position, in which the actuating element (34) is released from its fastening and is reset into the first position by means of a spring element (54). At the same time, a spring (56) causes the locking member (22) to be adjusted from the release position into the locking position.
