Definitions

  • the invention relates to a releasable handle attachment according to the preamble of claim 1.
  • a guide and holding part connected to a handle has projecting fastening legs arranged in holding lobes of a bristle body.
  • Spring clips are furthermore attached to the guide and holding part, the respective ends of which protrude freely and project approximately parallel to the fastening legs as clip clips engage in assigned clip holes in the bristle body.
  • the guide and holding part is provided with a tensioning element for clamping the clamping bracket in a clamping position in the clamping holes and for relaxing the clamping bracket in a release position of the guide and holding part relative to the bristle body.
  • the tensioning element is designed as a pivot lever supported against the guide and holding part, which rests with eccentrically acting actuators against the spring clip and can be pivoted between two end positions in which the clamping clip ent are neither tense nor relaxed.
  • This detachable handle attachment has proven itself extremely well in practice; since the fastening legs and the clamping brackets rest only with relatively small contact surfaces in the clamping holes of the bristle body, they must consist of relatively high-strength materials. For this reason, the clamping bracket is usually made of stable spring wire. Furthermore, this configuration requires an assembly effort that still seems to be in need of simplification.
  • the invention is therefore based on the object of developing such a handle attachment in such a way that a large-area contact between the holding part and the bristle body is achieved.
  • assembly is particularly simple since the two fastening parts only have to be placed against one another after insertion of the tensioning element and need to be pushed together into the handle. It also becomes a maximum possible distance between the handle-side clamping point of the two fastening parts on the one hand and the point facing the bristle body, where the bracing between the holding part and the bristle body takes place. This also makes it possible to use particularly little elastic, generally relatively cheap plastics.
  • a particularly secure connection between the holding part and the bristle body is achieved by the measures according to claim 3.
  • such positive connections are dovetail-like.
  • a particularly advantageous constructive solution to this is specified in claim 4.
  • a holding part 2 is fastened in the embodiment according to FIGS. 1 to 3 and a holding part 2 'in the embodiment according to FIGS. 4 to 6, which essentially has the shape of an isosceles, light has an obtuse-angled triangle.
  • Both holding parts 2 and 2 ' essentially consist of two fastening parts 3, 4 and 3', 4 'and a clamping element 5.
  • the two fastening parts 3, 4 are approximately plate-shaped in their basic form, the one fastening part 3 on the two sides extending from the handle 1 having a raised edge 6, which has the contour on its inside of the other fastening part 4 is adapted so that it is practically arranged in the other fastening part 3 in the assembled state.
  • the two edge regions 8, 9 facing a bristle body 7 of a broom or scrubber are exposed.
  • a hollow pin 1o is attached, the outer diameter of which is adapted to the inner diameter of the tubular stem 1, so that this fastening part 3 can be fastened tightly by inserting the pin 1o into the stem 1 on the latter.
  • a - not necessarily hollow - pin 11 is also attached, which can be inserted into the hole 12 towards the fastening part 3 in the pin 10, whereby the two fastening parts 3, 4 perpendicular to the longitudinal axis 13 of the stem 1 and the holding part 2 fixed in itself, however slightly interconnectable.
  • the two fastening parts 3, 4 as can be seen in particular from FIG. 2 — abut one another with their edge regions 8, 9, or these can be pressed against one another.
  • a cavity 14 extending transversely to the longitudinal axis 13 is formed between them and in them, in which an elongated pin serving as an actuator 15 with a non-circular cross section is arranged.
  • Both fastening parts 3, 4 are in their relaxed position, in which the two edge regions 8, 9 of the fastening parts 3, 4 practically lie against one another.
  • the pivot lever 16 is pivoted away from the fastening part 3 and thus from the handle 1, so it is clearly in an open position.
  • an elongated hole-like recess 2o which is adapted to the cross section of the holding part 2 at the edge regions 8, 9, is formed, which in the region of its outer longitudinal edges has inwardly projecting bead-like projections 21, which have corresponding groove-like depressions 22 on the outer surface of the respective one Fastening part 3, 4 are assigned in the edge area 8, 9.
  • the holding part 2 with the edge regions 8, 9 can be inserted into the recess 20 in the bristle body 7.
  • the groove-like depressions 22 lie over the projections 21, ie the web-like sections 23 of the fastening parts 3 delimiting the depressions 22 to the edge region 8 or 9 , 4 lay behind the projections 21, so that the holding part 2 and thus also the handle 1 is completely fixed, although releasably connected to the bristle body 7.
  • the handle-side connection between the two fastening parts 3, 4 should be largely free of play in order to achieve a wobble-free fit.
  • the two fastening parts 3, 4 and, of course, the tensioning element consisting of actuator 15 with swivel lever 16 can each be injection molded exclusively from a suitable plastic.
  • the surface pressures and the stresses that occur are very low. For this reason, there is no fear of the bristle body 7 breaking out in the region of its recess 20.
  • the two fastening parts 3 ', 4' lie all around one another. At each fastening part 3 ', 4' half pin is formed 1 0 '. The two pins 1 0 'complement each other in the handle 1 to form a mounting pin. The connection of the two fastening parts 3 ', 4' to the holding part 2 'thus takes place directly through the handle 1.
  • edge regions 8 ', 9' of the fastening parts 3 ', 4' do not run approximately perpendicular to the longitudinal axis 13 of the handle 1 in this embodiment, but rather somewhat inclined, as can be seen from FIGS. 4 and 5, so that the associated bottom surface of the recess in Bristle body can lie in its main plane, while the bottom 24 of the recess 2o in the embodiment according to FIGS. 1 to 3 is inclined in accordance with the inclined position of the stem 1 relative to the bristle body 7, as can be seen from FIGS. 2 and 3.
  • the groove-like recess 22 'does not extend around the entire holding part 2, but is interrupted in the central region.
  • the two fixing parts 3 ', 4' are held in their common parting plane immovably against each other, is at the one half-pin 1 0 ', a cam 25 and at the other half-pin 1o' a corresponding recess 26 is provided at the assigned point, so that a positive connection between the two parts is achieved.
  • cam recesses can be provided at different locations.
  • a significant advantage of the embodiment according to the invention is that a bristle body 7 of scrubbers, house brooms, street brooms and the like, which is arranged in the plane of the longitudinal axis 13 of the handle 1 or 2 ′, can be attached either perpendicularly or inclined to the longitudinal axis. Whilst the arrangement of the bristle body in the case of house brooms is carried out exactly perpendicular to the longitudinal axis of the handle, scrubbers and street brooms are also inclined to the longitudinal axis. In this case, the adaptation is carried out exclusively on the side of the bristle body, namely by arranging the slot-like recess either perpendicular to the longitudinal axis or correspondingly inclined. This is another important advantage of the configuration according to the invention.
