Definitions

  • the invention relates to a wiper frame of a floor wiper with bow-shaped frame parts to be inserted into the end pockets of an interchangeable cover, one of which is in the plane of a gimbal-mounted shaft sleeve which is gimbally fastened to a bearing shaft which runs on at least two bearings connected to the frame part and which is pivotable about the longitudinal axis of the frame equipped carrier plate fixed and the other to fold to the bearings of the bearing shaft by 90 °, attached to the carrier plate and fold in the extended position pivoted into the plane of the carrier plate with the aid of a locking device.
  • a cleaning device with an end pocket for the entry of the end sections of an interchangeable cover having a cross member arranged on a handle is known from DE-OS 27 04 417.
  • the crossmember consists of two crossmember parts to be displaced relative to one another to reduce the end spacing, the position of use of which is to be locked by a locking member which can be rotated with the handle.
  • the resulting telescopic displacement of the two cross member parts relative to one another as a result of the rotary movement of the handle requires a relatively complex mechanism which cannot ensure that a used cover can be deposited without the intervention of one hand.
  • the locking device In a wiper frame of a floor wiper described in the older EP-OS 0017208, the locking device consists of an extension arm of the frame part to be swung out in the extended position of the device into a slot of the fixed frame part and one to be pushed in the extended position between the fixed frame part and the extension arm, on fixed frame part pivoting bolt tongue. Locking and unlocking can be done with this wiper frame only by operating the locking device.
  • the locking device is to be operated with the foot so that the interrelation - especially after use - does not have to be touched by hand when detaching from the wiping frame. Since the foot-operated locking device can only be released when the device is placed on the floor, it is, however, a certain difficulty to throw a used mop cover into a waste container after the lock has been released using the unlocked wiper frame.
  • the invention has for its object to design the wiping frame of the type mentioned so that the locking and unlocking of the foldable frame part in the extended position of the device without additional rocker arm by actuating the handle so that accidental loosening is not expected in normal handling is.
  • the solution according to the invention is characterized by a bracket coupled to the bearing shaft with a substantially semicircular receptacle which is offset by approximately 90 ° to the longitudinal axis of the bearing shaft for a free leg of the to be defined in the extended position with the bracket, approximately parallel to the longitudinal axis folding frame part.
  • the bracket thus forms, together with the free leg, the locking device to be actuated according to the invention, directly by pivoting (i.e. not rotating) the handle inserted into the handle sleeve.
  • the bracket itself can be cohesive, for example by welding, with the bearing shaft act connected metal bow.
  • a possibly more cost-effective version of the bracket that is more suitable for series production consists of one, preferably of Plastic, molded part with an approximately semicircular recess or groove offset by approximately 90 ° to the longitudinal axis for inserting and receiving the free leg.
  • the molded part then has an opening for attaching to the bearing shaft, which is secured against rotation; in contrast to the integral connection, a positive or non-positive connection is provided here.
  • the invention is based on the fact that the handle when handling the device practically only in the area of the right angle spanned between the vertical with respect to the floor or the support plate and the horizontal running parallel to the support plate - back and forth and on and is pivoted off. If the arrangement is made so that the bracket can only be brought into or out of engagement with the leg of the foldable frame part to be locked only by pivoting the handle into the remaining right angle of its freedom of movement, the invention achieves that the locking or Unlocking of the wiper frame can be effected by a simple swiveling movement of the wiper handle into an angular range not used in normal handling. Accordingly, since the typical movement sequence when using the device is taken into account and utilized for the locking function, the wiper frame according to the invention does not require any special rocker arm or the like which increases the outlay and may make handling more difficult.
  • the device according to the invention is particularly easy to handle when the bearing shaft is approximately S-shaped in the area between two terminal bearings with a central piece running perpendicular to the longitudinal direction of the frame the S-shape is bent and when the semicircular bracket can be locked or unlocked by pivoting the handle attached to the center piece with the aid of the handle sleeve around the longitudinal axis of the bearing shaft with the free leg of the frame part to be folded.
  • the bracket can, in particular in the area between the two end bearings, be molded or coupled to the bearing shaft. In the latter case, the bracket, which is preferably in the form of a molded plastic part, is in particular attached to a part of the S-shaped center piece which runs obliquely with respect to the longitudinal axis.
  • bracket With a correspondingly obliquely shaped slot of the shaped bracket, there is a positive or non-positive connection that excludes a relative rotation of the bracket and bearing shaft.
  • the arrangement is also simple if the bracket itself is formed from an extension piece of the shaft extending beyond a terminal bearing of the bearing shaft. Because of the better fit, the clip-on bracket is usually cheaper for series production.
  • a locking device or locking device integrated in the gimbal handle holder which, in addition to the leg of the frame part to be folded, which is to be locked, consists only of a bracket attached to the longitudinal bearing shaft of the gimbal handle suspension. If here and in the following a brief mention is made of a (clip-on) plastic bracket, this points to the difference to the bow-shaped bracket (to be attached to the material), which will probably always consist of metal.
  • the clip-on bracket can - as already mentioned - also be made of other solid materials than plastic, e.g. be made of metal.
  • the wiper frame - preferably made of stainless steel or galvanized steel sheet support plate 1, the longitudinal edges 2 of which should be bent semi-tubular on the underside.
  • the latter bend serves on the one hand to increase the stability of the plate 1 and on the other hand to accommodate the fixed frame part 3, which is designed, for example, as a bracket.
  • the temple ends of the fixed frame part 3 can within the semi-tubular bend at the edges 2 of the Carrier plate 1 can be fixed or also resiliently mounted in the longitudinal direction of the plate.
  • the pivotable frame part 5, which consists of a flap bracket, is also fastened to the carrier plate 1 in bearings 4.
  • the cardanic holder of the stem sleeve 7, designated overall by 6, is pivotally arranged in bearings 8 in the center.
  • the dashed longitudinal axis 9 of the S-shaped bearing shaft 10 of the gimbal bracket 6 runs parallel to the direction of the width of the frame and perpendicular to the dashed bearing axis 11 of the bearing 4 of the frame part 5 to be pivoted.
  • the bearing shaft 10 is in the area between its terminal bearings 8 bent approximately S-shaped so that a perpendicular to the longitudinal axis 9 center piece 12 is formed as a bearing shaft of the stem sleeve 7.
  • a stem 14 can be inserted into the open end of the stem sleeve 7.
  • bracket 15 Firmly connected to the S-shaped bearing shaft 10 in the exemplary embodiment is a semicircular bracket 15 which is offset by 90 ° to the longitudinal axis 9 of the bearing shaft 10.
  • This bracket 15 can either be attached to or molded onto the area between the two bearings 8 of the bearing shaft 10 or can be formed from an extension piece 19 of the shaft extending beyond a terminal bearing 8 according to FIG. 6 of the extended bearing shaft 10.
  • the bracket 15 represents one element of the lock 15 according to the invention.
  • the other element of the lock is formed by an extended, free leg 16 (or 20 according to FIG. 6) of the foldable frame part 5.
  • the free leg 16 or 20 is bent back after the bearing 4 approximately within the plane of the frame part 5 by 90 ° and protrudes in the Stretching position of the wiper frame either according to FIGS. 1 to 5 in a central recess 17 of the carrier plate 1 or according to FIG. 6 on the side of the foldable bracket 15 by, for example, 2 cm beyond the carrier plate 1.
  • the longitudinal end 18 of the free leg 16 can be lifted somewhat out of the plane of the folding bracket or frame part 5 in the direction of the bearing axis 9, such that the arch of the bracket 15 engaging under the longitudinal end 18 is not appreciably on the underside of the frame via the carrier plate 1 projects down.
  • FIG. 3 shows the state of the locking, in which the bracket 15 engages under the longitudinal end 18 of the free leg 16 of the frame part 5 to be folded
  • FIG. 4 shows how the handle sleeve 7 is pivoted by approximately 180 ° with respect to FIG the longitudinal axis 9 of the bracket 15 comes out of engagement with the fingeron leg 16.
  • the foldable frame part 5 is then - with the frame raised - by gravity from the system on the support plate 1 according to FIG. 5 and swings down about its bearing 4.
  • an arched bracket 15 which is integrally formed on the bearing shaft 10, in particular made of steel or stainless steel, and is welded on. 7 and 8, in which the same parts as in the previous figures are referred to, can achieve a more cost-effective and fit-in-series version with a, preferably made of plastic, clip-on form bracket 21.
  • This bracket 21, which is offset by 90 ° to the longitudinal axis 9, can be firmly and non-rotatably coupled to the S-shaped central part 12 of the bearing shaft 10 by simply plugging it on.
  • the semicircular, in particular formed as a groove 22, recess of the molded part can receive the free leg 16 of the foldable frame part 5 similar to the molded metal bracket 15.
  • the groove 22 has an inlet opening 23 which corresponds to the longitudinal end of the metal bracket 15.
  • the attachable bracket 21 should preferably consist of plastic because of the manufacturing effort.
  • the molded part according to the invention has a slip-on slot 24 which is to be designed in particular in such a way that a positive and non-rotatable connection to the bearing shaft 10 can be established by plugging on the bracket 21.
  • the hygienically perfect, clean cover provided with terminal pockets can be touched by hand on the unlocked wiper frame, for example folded to an angle of 20 to 30 °, as shown in FIG. 5.
  • the handle 14 is pivoted according to the preceding explanations to the lowest possible level in the angular range in which the wiper is not used in normal handling.
  • the folded-down frame part 5 is folded parallel to the carrier plate 1 after the cover has been pushed onto the bearing.
  • the free, bent back leg 16 of the foldable frame part 5 passes through the central recess 17 of the carrier plate 1 or 6 in the middle next to the carrier plate 1 in a position in which the longitudinal end 18 of the free leg 16 can be gripped by the bracket 15 (FIGS. 1 to 5) or in the groove 22 (FIG. 7).
  • the stem 14 held in the S-shaped bearing shaft 10 only needs to be pivoted by approximately 180 ° and the bracket located on the bearing shaft 10 detects the free leg 16.
  • the device can be held by the handle, rotated through 180 ° using a container provided for storage, and then lifted. Since during this movement the bracket according to the invention releases the free, bent-back leg 16 (FIG. 4 or 8), the foldable frame part 5 pivots due to the force of gravity and the cover falls off by itself.
  • the device according to the invention is therefore suitable, inter alia. especially for hospital cleaning, because the staff no longer comes into contact with the used and possibly bacterially contaminated covers. It is particularly advantageous that the mop cover can be loosened only by pivoting the handle and can therefore be easily inserted into a storage container when loosening.
  • the bow-shaped frame parts 3 and 5 according to the invention can be bent semicircularly at the longitudinal ends approximately according to FIG. 1 or can be provided with rounded ends according to FIG. 6.
  • rollers not shown, can be placed on the end parts of the brackets which are transverse to the longitudinal axis 9 and which facilitate insertion into the mop cover.
  • the two frame parts 3 and 5 expediently consist of approximately 6 mm thick round steel.
