Definitions

  • the invention relates to a device for releasably fastening cleaning devices, e.g. Brooms, scrubbers or the like, on a handle by means of a connecting part which has two fork-shaped fastening members which are under a restoring force and a tensioning member rotatably guided between them, by means of which the ends of the fastening members can be clamped against recesses of the device body against the restoring force.
  • cleaning devices e.g. Brooms, scrubbers or the like
  • Devices of this structure are known in a variety of embodiments (DE-PS 439 643, US - PS 1 692 110, DE-AS 2 606 400).
  • the invention relates in particular to devices in which the fork-shaped fastening members are formed in one piece and by means of a tension member rotatably guided between them Shape of a cam or the like. can be moved into a clamping position between the opening position that occurs under the effect of the restoring force (DE-AS 2 606 400).
  • the fastening members consist of a fork-shaped round steel bar which engages with its two ends in the recesses in the device body.
  • the two legs of the round steel run approximately parallel to the handle, but are bent out in opposite directions to form the extension.
  • a tendon in the form of a chamfer-like cam disc is inserted, which can be rotated with a kind of toggle handle, so that the fork-shaped arms can be moved from the open position into a spread clamping position.
  • the tendon is designed as a one-piece plastic injection molded part.
  • this known device represents a mixed construction, which consequently requires corresponding forming tools, assembly tools etc. in the manufacturing operation. Furthermore, the attachment of the fork-shaped round steel to the handle makes special manufacturing measures necessary.
  • the invention is based, to simplify the previously described known device, especially in terms of production and assembly, the task.
  • fastening members are part of a one-piece injection molded plastic housing which is attached to the handle with a tubular extension, from the extension in the direction of the longitudinal extension of the device body extended and provided with a slot open to the device body, lying in the axis of the handle, which has an extension as a pivot bearing for the tendon at a distance from the open side.
  • the entire connecting part that is to say the housing forming the fastening members and the tensioning member, from plastic, so that both parts can be injection molded from plastic. All that remains of assembly work is fixing the housing on the arm and inserting the tendon. Since the housing has a tubular extension for the stem, one can use common techniques in the field of cleaning devices.
  • the tensioning element is inserted, as in the prior art of the generic type, by simply pushing it into the slot until it has found its position in the extension serving as a pivot bearing.
  • the connector is housing-like made of plastic.
  • the housing consists of two shells divided approximately parallel to the longitudinal extension of the device body, which have a circumferential notch on the outside. These two shell parts can be pressed apart by a type of cam roller, which also runs in the longitudinal direction and is provided with an outwardly extending lever arm. In this clamping position, corresponding ribs on the inside of a housing molded onto the top of the device body engage in the notches of the two housing shells a.
  • the connecting part is in three parts, that is to say has a part more than the device according to the invention.
  • this device inevitably requires a special design on the top of the device body, which in itself has nothing to do with its actual function. This training is complex, complicates the manipulation of the device body when inserting bristles or the like and also gives it an unsightly appearance.
  • the plastic housing on its front side facing the device body near its outer ends has hooks which are curved outwards for engaging in the recesses in the device body.
  • these cutouts can be molded into the device body, but they can also be designed as simple openings so that the hooks can reach through and grip the device body on the underside.
  • the plastic housing is triangular in view and is open on its end face facing the device body, the approximately paratlel triangular walls each having a slot with an extension acting as a pivot bearing for a tendon mounted in both extensions.
  • the triangular walls of the plastic housing can be reinforced by ribs in the area of the slot in order to be able to better absorb the forces in the clamping position and to introduce them into the wall.
  • the tendon preferably has oval cams mounted in the extensions and edge flanges lying against the walls of the plastic housing. On the one hand, this enables simple actuation of the device and, on the other hand, ensures secure guidance of the tendon in the housing.
  • the enlargements of the slots can have an oval shape corresponding to the cams on the tendon, the longitudinal axis of which lies in the slot axis, so that the device is in the open position when the cam is vertical and in the tensioned position when the cam is transverse.
  • a toggle handle is arranged on one of the edge flanges, which is parallel to the handle in the clamping position.
  • Such a toggle handle adapts particularly well to the overall outer shape of the device. In the tensioned position, the toggle handle does not protrude on either side of the device, so that an untimely opening, for example when bumping into furniture or the like with the cleaning device, is not possible.
  • the open end edge of the plastic housing runs with a corresponding curvature and lies snugly in the tensioned position of the upper side of the device body.
  • the top of the device body can be convex and the front edge of the plastic housing can be concave.
  • a stem 1, for. B. from metal lrohr, shown for a schematically indicated cleaning device 2, on the device body 3 bristles, hair or the like. are attached, the outer boundary of which is indicated by a dash-dotted line 4.
  • the connection part designated overall by 5
  • the plastic housing 6 has two triangular walls 8, 9 (FIG. 2) running approximately parallel to one another, which are of isosceles and are connected to one another by their equally long legs via rounded housing sections 10.
  • the plastic housing 6 has a tubular extension 11, by means of which it is attached to the handle 1 in a conventional manner.
  • the triangular walls 8, 9 are provided with a slot 12 which is attached to the tubular extension 11 and which is narrow in the upper region and somewhat wider in the lower region 13. In between there is an oval extension 14, the longitudinal axis of which lies in the direction of the slot axis.
  • outwardly curved hooks 17, 18 are formed on the lower end edges 15, 16, which converge to form a larger wall thickness in the outer region, which engage through elongate recesses 19, 20 on the device body 3.
  • the tendon which is denoted overall by 7, is inserted, which has two cam disks 21, 22 shaped in accordance with the extension 14 (FIG. 2). Furthermore, the tendon on the outer end faces of the cam disks 21, 22 is provided with edge flanges 23, 24, by means of which the tendon 7 is secured on the outer sides of the side walls 8, 9 against axial displacement. Likewise, the tendon can also have edge flanges lying inside the side walls.
  • the cam disks 21, 22 are connected to one another via a cross-shaped carrier 25 which, like the edge flanges 23, 24, is designed somewhat wider than the extension 14 at its widest point.
  • a toggle handle 26 is arranged as a handle.
  • the two slots 12, 13 are reinforced with the extension 14 on the inside of both side walls 8, 9 by ribs 27, 28 on the edge.
  • the side wall 8 is guided slightly further down than the side wall 9 of the plastic housing 6, so that the handle 1 can be attached to the device body 3 in a correspondingly inclined position. Furthermore, the lower end edges on the open side of the housing 6, as can be seen in FIG. 1, are slightly concave, so that they fit snugly against a correspondingly convex surface of the device body 3 in the clamping position.
