Definitions

  • the invention relates to a coupling device between a cleaning device and a handle according to the preamble of claim 1.
  • the cleaning utensils required for various cleaning tasks are usually carried with the help of a cleaning trolley.
  • Many cleaning utensils have a handle on which a cleaning device is attached. Examples of such cleaning devices are mop holders, cobwebs, washers and pullers, which are usually firmly mounted on an associated handle.
  • the connection between the handle and the cleaning device can be realized via a riveted or screwed connection. Because of the different cleaning equipment, various stems and holders must often be carried by a cleaning person on the cleaning trolley, which on the one hand requires space on the cleaning trolley, but on the other hand can negatively influence the overall weight and thus the maneuverability of the cleaning trolley.
  • the handles are therefore used several times differently. It is known to connect the cleaning equipment with the handle by the cleaning device is plugged by means of a cone connection on the handle or a spring pin is arranged in a stem bore of the handle, which engages elastically in a corresponding hole in the cleaning head. Such connections with locking pins and springs are often unwieldy and make it difficult to quickly change the cleaning equipment.
  • the invention has for its object to propose a connection between a cleaning device and a handle, which is easy to operate and is also suitable for the movement sequences in cleaning process. This object is achieved by a coupling device between a cleaning device and a handle with the features of claim 1. Preferred embodiments follow from the remaining claims.
  • the coupling device according to the invention between a cleaning device and a handle comprises a coupling receptacle with at least one actuating element and a coupling pin which can be inserted into the coupling receptacle and can be locked therein.
  • the coupling device is characterized in that the coupling pin and the coupling receptacle are shaped such that in the locking state of the coupling pin in the coupling receptacle is held positively in both the axial direction and in the radial direction, and the coupling receptacle manually, preferably with only one hand, from the locking state is movable in an open position.
  • both axial forces and radial forces can be transmitted by means of the coupling device according to the invention.
  • the coupling receptacle is easily movable from the locking state to the open position, and preferably the coupling device can be actuated with only a single hand. This is when changing from cleaning devices of particular interest, because with one hand the cleaning device is held and with the other hand the coupling device is actuated, so that the cleaning device does not fall when loosening the coupling device.
  • the coupling receptacle on two actuators which are each manually pivotable about a hinge, wherein the actuators are biased into a position corresponding to the locked state in the coupled state.
  • the coupling device further comprises an elastic ejection element which is elastically deformed in the locked state.
  • the elastic deformation of the ejection element can lie therein both in a compression of a compressible element, as well as in a bending deformation of the ejection element. Due to the elastic deformation in the locking state, the restoring force of the elastic ejection element can be used as soon as the coupling device is brought into the open position.
  • the elastic restoring force springs back the ejection element, which is in the locked state in contact with the coupling pin, back into the starting position and can support the coupling pin in its movement out of the coupling receptacle out.
  • the coupling receptacle and the coupling pin are formed so that the coupling pin can be inserted and locked in several radial positions, preferably in four radial positions at equal angular intervals, for coupling reception.
  • This measure also facilitates the production of the connection between cleaning device and handle. It is no longer necessary to pay attention to a precisely defined relative angular position between the coupling receptacle and the coupling journal, but the connection can take place in several radial positions.
  • the coupling pin has a conically tapered, distal end.
  • the distal end of the coupling pin is the end which is inserted in the coupling device furthest in the coupling receptacle.
  • the coupling device further comprises a recessed grip on each actuating element. Also, this measure is convenient operation, since when gripping the actuators of the coupling receptacle automatically find the fingers of a user in an ergonomically comfortable and suitable for operating the coupling device position.
  • the coupling device further comprises an insertion bevel on each actuating element, which is arranged so that the coupling pin is insertable into the coupling receptacle.
  • the coupling device further comprises a means for synchronizing the movement of the actuating elements.
  • This measure also serves the easy and convenient operation of the coupling device. If the movement of the actuators is synchronized, only one actuator must be manually operated, while the one or other other actuators are automatically brought by means of the means for synchronizing the movement in the respective corresponding position.
  • the means for synchronizing the movement of the actuating elements is a toothing of the actuating elements in the coupling receptacle. This represents a technically very simple and maintenance-free solution.
  • the coupling device further comprises a pivot joint, which is arranged at the proximal end of the coupling pin and comprises a flexible disc and a joint receptacle.
  • the coupling device further comprises a means for blocking the movement of the pivot joint.
  • a means for blocking the movement of the pivot joint depends on the special type of cleaning device, but also its operation in certain cleaning tasks. Sometimes it makes sense to block the hinge, for example, because it works overhead and simplifies the cleaning task if, after blocking the movement of the hinge, an additional degree of freedom has been eliminated.
  • the means for blocking the movement of the rotary joint comprises a manually operable blocking switch, which is connected to a blocking element which frictionally or positively prevents or at least impedes relative movement between the flexible joint and the joint receptacle.
  • the blocking switch may be any manually operable element which is actuated either by means of a rotary movement or a sliding movement.
  • a positive locking element can be realized by means of ribs or similar geometries on the joint disk, wherein the blocking element is arranged on the joint mount and can engage in the ribs of the joint disk.
  • a form-fitting effect for example, uses a blocking element made of a material with a high coefficient of friction.
  • the coupling device can preferably be connectable to an adapter piece, which is tuned to the geometry of a special handle or a special cleaning device.
  • the coupling device according to the invention can be combined with both cleaning equipment from third-party suppliers, as well as with third-party operators.
  • the adapter piece is either provided with the coupling pin or the coupling receptacle or connectable at the proximal end with the coupling receptacle or the coupling pin.
  • a coupling device according to the invention is shown in sectional view.
  • Fig. 1 is the locking state and in Fig. 2 the opening position shown.
  • the coupling device according to the invention which is generally designated by reference numeral 10, consists of a coupling receptacle 12 and a coupling pin 14.
  • the coupling receptacle 12 has two actuating elements 16, which are each designed as a button and pivotable about a pivot 18. Both actuators 18 have a hook 20 which is dimensioned to be in the in Fig. 1 shown locking state positively engage in a recess 22 on the coupling pin 14. Furthermore, the actuators 16, as in Fig.
  • the two actuating elements 16 are by means of a compression spring whose axial ends engage in the spring receivers 26 of the actuating elements 16, in the in Fig. 1 biased locking position shown.
  • the coupling receptacle 12 is provided with a pipe receptacle 28 and a continuous radial bore 30 and radial blind bore 32.
  • the holes 30, 32 are used in a conventional manner the connection between the coupling receptacle 12 and a handle, not shown in the figures, for example by means of a conventional spring pin.
  • shots or adapters for common handling such as handles with a diameter of 23.5mm or a conical recording (so-called "painter cone").
  • the two actuating elements 16 are pivoted about the pivot joints 18. To achieve this, the two actuating elements 16 in the region of the recessed grips 34 (see Fig. 4 ) are compressed. As a result, a rotational movement about the axes of rotation 18 is generated, by which the distance between the hook 20 increases, whereby they are moved out of the recesses 22 on the coupling pin 14 and release it.
  • a pressure on the recessed grips 34 is to be compared with the compression of a clothespin, since the arranged between the spring receivers 26, not shown in the figures compression spring, the actuators 16 in the in the Fig. 1 and 3 pretensions shown locking position.
  • the actuating elements in addition to a toothing 36 which is designed so that each lugs 38 and 40 on the actuating elements alternately at the top and Contact the lower side. If now one of the actuating elements 16 is moved, the second actuating element 16 is moved in the same way with the aid of the toothing 36 and in particular the mutual contact of the lugs 38 and 40. It is thus ultimately only necessary to actuate one of the recessed grips 34 in order to release the coupling device.
  • the release of the coupling device is further supported by an ejection spring 42, which in Fig. 3 in a preloaded position, and in Fig. 4 is shown in a relaxed position. Now, if the coupling pin is inserted into the coupling receptacle, the ejection spring 42 is biased. When releasing the coupling device, the ejection spring 42 springs back into its original position and thereby supports the disengagement of the coupling pin from the coupling element.
  • the coupling device 10 is also designed so that it produces a positive connection in the radial direction.
  • the coupling pin 14, as best of the three-dimensional representations in FIGS. 7 and 10 can be seen, provided with four ribs 44 which are each at an angle of 90 ° to each other and therefore allow four possible coupling positions between the coupling pin 14 and the coupling receptacle 12.
  • the coupling receptacle 12 is also provided in accordance with the cross-shaped arrangement of the ribs 44 and coupling pin 14 with a receiving volume in the form of a regular cross.
  • the ribs 44 and the associated receiving spaces in the coupling receptacle allow a radial similar to a spline in a shaft / hub connection Fixation and a desired power transmission in the radial direction.
  • coupling pin is shown adjoining the coupling pin 14 pivot 46, which consists of a flexible disc 48 and two joint receptacles 50.
  • the flexible disk and joint receiver are movable relative to one another about a joint shaft 52.
  • a brake lever 54 is provided, which is manually operable and about an axis of rotation relative to the joint seat 50 is movable.
  • a brake pad 56 of the Rigid connected to the brake lever is a brake pad 56 of the, as in particular from the sectional views in the 6 and 9 is apparent, has an elliptical shape and is located in a space 60 between the coupling pin 14 and the flexible disc 48.
  • the brake lever 54 by a user manually from the in Fig. 5 represented, dissolved positions in the in Fig. 8 shown locking position, so results in a corresponding rotational movement of the rigidly connected to the brake lever brake pad 56, as can be seen in particular from the comparison 6 and 9 results.
  • rotary joint 46 is now located, for example, on a mop holder, a free movement of the joint for transverse movements and thus for a floor cleaning is optimal, since pivoting movements are carried out for the floor cleaning. If the same mop holder is now used for cleaning vertical surfaces, it is advantageous to block the pivot 46.
  • the brake pad 56 is made of a rubbery material such as TPE and thus has a high Friction coefficients in order to produce a positive locking between the flexible disc 48 and the brake pad 56, and thus between the flexible disc 48 and rigidly connected to the coupling pin 14 joint receptacle 50.
  • locking lugs are provided on the brake lever, which engage in locking recesses 58 to hold the brake lever 54 in the locked position until the user again in the in Fig. 5 shown position in which the hinge 46 is no longer locked.
  • the locking pins 14 are provided at the distal end with a conical taper 62, which allows the convenient insertion of the coupling pin 14 in the coupling receptacle 12.
  • This tapered design together with the symmetrical cross-shaped design of the ribs, but also the synchronization of the two actuators 16 causes the coupling device is particularly easy to use. It provides sufficient support, is easily accessible and understandable even for untrained personnel in their function.
  • only a single actuating element must be pressed when releasing the coupling device, because the respective other actuating element is automatically actuated by the internal synchronization.
  • the coupling device is preferably operated similar to a clothespin, since this is a familiar movement.
  • an ejection spring can further facilitate the release of the coupling device.
  • the coupling between the coupling receptacle and the coupling pin also no separate manual operation is required, since the provision of the insertion bevels the connection automatically he follows.
  • An additional advantage is that the two hooks 20 visible, palpable, but also due to a clicking noise when snapping audibly engage in the recesses 22 on the coupling pin 14. A user can thus easily determine that the coupling device has been moved to the locking position.
