Definitions
- the invention relates to a cleaning device for a shaving head of a dry shaving apparatus with a receiving part formed in a housing, into which the dry shaving apparatus with its shaving head can be inserted, and with a contact dome of the housing, through which the end of the dry shaving apparatus facing away from the shaving head can be gripped and wherein a button is arranged in this end of the contact dome, with electrical connections which can be moved by means of the button, for the electrical contacting of contact pins of the dry shaving apparatus with the cleaning device.
- the dry shaving apparatus is contacted via its contact pins, which are connected to electrical connections in the cleaning device.
- the electrical connections are arranged in the upper end of a contact dome, where they can be moved in the direction of the contact pins by means of a button. When the contact pins are reached, the electrical connections are held in this position by locking hooks.
- the dry shaving apparatus in the cleaning device is thus electrically contacted and locked.
- the disadvantage of the cleaning device is that the structure of the contact dome with its movable part is relatively complex and therefore complex to manufacture and assemble.
- the contact pins of the dry shaver are not always in the exact same place. The deviations are due, on the one hand, to the manufacturing tolerances of the cleaning device and the dry shaving apparatus.
- the position of the dry shaving apparatus can vary slightly when it is inserted into the cleaning device. These deviations, even if only slight, result in large forces acting on the electrical connections when contacting the dry shaving apparatus, which can lead to high mechanical stress on the contact dome.
- the latching hooks in particular are affected by these mechanical loads. Such loads can lead to increased wear. Under unfavorable circumstances the wear can be so great that the contact dome device no longer securely engages, as a result of which, in the worst case, the dry shaver can no longer be electrically contacted.
- the present invention is therefore based on the object of providing a cleaning device of the type mentioned at the outset, which is of simple construction and enables reliable contacting of the dry shaving apparatus with little stress on the locking mechanism and the contact dome.
- This object is achieved in that a tolerance compensation device is arranged between the electrical connections and the button.
- the tolerance compensation device enables the compensation of manufacturing-related tolerances and the tolerances that result from the incorrect insertion of the dry shaving apparatus into the cleaning device.
- the main advantage is that the button and the electrical connections are no longer directly connected. As a result, the button movement is decoupled from the movement of the electrical connections. The occurrence of large plug-in forces for contacting is avoided. This leads to a considerable reduction in the loads on the electrical connection and the contact dome. In particular, the latching elements are subjected to less mechanical stress, as a result of which the locking mechanism has a significantly longer service life.
- the tolerance compensation device is a rocker loaded with a spring, which is supported by the spring on the button and on which the electrical connections are arranged.
- the rocker interacts with the button for contacting via the spring. Electrical connections on the rocker are used to contact the dry shaver.
- the rocker with the electrical connections is moved in the direction of the contact pins of the dry shaving apparatus. If the contact is made as a result of tolerances before the button has reached its locking position, the spring on the rocker allows the button to continue to move, while the rocker remains in its position due to the contact forces of the electrical connections. From this point on, the button is moved against the spring until it has reached its locking position.
- the advantage of such a tolerance compensation device is the small number of parts.
- the tolerance compensation device requires only a small amount of effort in assembly, which makes it particularly inexpensive.
- the rocker is preferably pivotally mounted in the contact dome or a component additionally arranged in the contact dome.
- the contact dome has proven to be favorable for mounting the rocker, since a bearing point for the rocker can be produced particularly easily at this point. This also has the advantage that an existing contact dome can continue to be used with minor changes.
- the contact dome is also a component that has sufficient strength so that the bearing point does not require any additional reinforcements of the contact dome.
- the bearing point can be arranged on a component additionally located in the contact dome. This has the advantage that this component can be specially adapted to the rocker.
- the button can have means for taking the seesaw, preferably hooks engaging behind the seesaw.
- the spring between the button and the rocker can be loosely arranged between the two components or connected on one side to the rocker or the button. These configurations are characterized by a low installation effort. In contrast, a spring clamped on both sides allows the rocker to be carried when the button is moved. Otherwise, driver elements, preferably hooks, are arranged on the button or the rocker in order to move the rocker with the button.
- the button engages between the electrical connections and the pivot point of the rocker.
- the button then moves a short stroke when making contact, while the electrical connections carry out a longer stroke.
- a corresponding stroke is available for contacting and to compensate for tolerances.
- the stroke of the button can be designed as in existing cleaning devices, so that the user can operate the new cleaning device as usual.
- the electrical connections are arranged between the pivot point of the rocker and the button acting via the spring, so that the button has a larger stroke than the electrical connections. This arrangement is advantageous for small and sensitive contacts, since it enables smoother contacting.
- the electrical connections can be contact plates which are arranged on the rocker, preferably clamped on one side.
- the contact plates can be attached to the rocker by means of a snap or plug connection.
- the contact plates can be extrusion-coated with the plastic during the injection molding in order to be attached to the rocker.
- the rocker is designed such that the individual contact plates are arranged in a receptacle within the rocker.
- the individual arrangement of the connections also has the advantage that height tolerances between the contact pins of the dry shaving apparatus are compensated for.
- the contact plates have a resilient area in the direction of the contact pins to be contacted. This allows the contact plates to compensate for tolerances and support the effect of the tolerance compensation device.
- hooks are arranged on the contact plates, which interact with stops on the rocker. The hooks limit the stroke of the contact plates, so that the contact plates move in the reversibly deformable area.
- the locking mechanism required for this has two locking positions. In the first latching position, the electrical connections are completely in the contact dome and the dry shaver can be inserted into the cleaning device. In the second latching position, the electrical connections are connected to the contact pins of the dry shaver. The electrical connections are held in their respective positions in both locking positions.
- the locking mechanism is particularly simple if the button for moving the electrical connections is an actuating element for the locking mechanism. For this purpose, the button has a slide which can be moved along a guide between the two locking positions. A straight line movement of the slide can be generated by taking the slide with the button. The design options for locking can be increased considerably if the slide is arranged to be movable transversely to the direction of movement of the button. In this way, two-dimensional tours can be implemented.
- the guide is particularly simple if it is aligned essentially transversely to the movement of the button.
- the first locking point can be formed by the upper end of the guide or by the upper housing limit.
- a complex design of the rest point is not necessary if the button and thus the slide are held in this rest point by means of a spring.
- the second rest point is arranged below the first rest point.
- a lower locking point formed within a heart curve which is known per se as a control link and which represents a section of the guide, has proven to be advantageous. Since the actual rest point is reached by reversing the direction of movement of the slide, the restoring force of the spring ensures that the slide sits securely in the heart curve. In addition, due to the characteristics of the heart curve, the user receives a haptic signal that the cleaning device is locked.
- the guide for the slide can be arranged in a separate component in the contact dome. However, an additional component can be dispensed with if the guide is arranged in the housing of the contact dome. This makes the locking mechanism particularly inexpensive.
- FIG. 1 a cleaning device
- FIG. 2 the arrangement of a tolerance compensation device in the contact dome
- FIG. 3 an exploded view of the tolerance compensation device according to FIG. 2
- FIG. 4 a section through the tolerance compensation device according to FIG. 2
- FIG. 5 shows a perspective illustration of the tolerance compensation device according to FIG. 3.
- the cleaning device 1 shown in FIG. 1 has a housing 2. Through an opening 3 in the housing 2, a dry shaving apparatus (not shown) can be inserted with its shaving head into a receiving part.
- the devices necessary for cleaning the dry shaving apparatus are arranged in the housing 2.
- the housing 2 has an approximately vertically extending contact dome 4.
- the button 5 which rests on the dry shaving apparatus inserted into the opening 3 and locks it.
- schematically illustrated contact plates 6 are moved downwards until they meet the contact pins of the dry shaving apparatus.
- the contact plates 6 are shown emerging downwards.
- the contact dome 4 shown in Figure 2 is composed of two housing parts 7, 8.
- the housing parts 7, 8 are locked together and held together by means of the locking hooks 9.
- the rear housing part 7 has an opening 10 in its upper end region, in which a button 5 is arranged.
- the button 5 is guided vertically movable in the front housing part 8.
- the front housing part 8 also has an opening 11 in its upper end region, through which a free end 12 of a rocker 13 passes when the cleaning device 1 is locked.
- the rocker 13 has two brackets 14, 15, which are arranged on both sides of the button 5. At the ends 12 opposite ends of the bracket 14, 15, a bolt 16 is formed, which form a pivot joint of the rocker 13.
- the end 12 of the rocker 13 has receptacles 17, in each of which a contact plate 6 is mounted.
- FIG. 3 shows a more detailed illustration of a tolerance compensation device.
- the arranged on the brackets 14, 15 of the rocker 13 bolts 16 are received by two bearings 18 in the housing part 8, so that the rocker 14 is pivotable.
- a receptacle 19 for a spring 20 is arranged vertically between the brackets 14, 15.
- the spring 20 presses against the button 5 from below.
- the housing part 8 also has a vertical receptacle 21 which forms a guide for a further spring 22 which also presses against the button 5 from below.
- Both springs 20, 22 are arranged on the part of the button 5 in receptacles 23, 24, which are located inside the button 5.
- the button 5 has guide elements 25 which are guided in the housing part 8.
- a slide 27 is arranged on the back of the button 5.
- the contact plates 6 are connected to the electrical lines, not shown, of the cleaning device 1 via cable clamps.
- the push button 5 By means of the spring 22 arranged in a receptacle 24 of the push button 5, the push button 5 is pressed upwards in the direction of the housing part 7 of the contact dome 4. By pressing the button 5, it is moved downward against the spring 22. The spring 20 supported on the rocker 13 presses the rocker 13 during this movement, which is then pivoted counterclockwise. As a result, the contact plates 6 are moved downward onto the contact pins (not shown) of the dry shaving apparatus. If the button 5 is moved further down after the contact has been made, the rocker 13 remains in its lower position and the button 5 is now moved against the spring force of the springs 22 and 20. The pushbutton movement is therefore independent of the movement for contacting. In the event that the spring 20 is compressed to its block length, any further movement of the button 5 downwards would increase the forces acting on the contact pins of the dry shaving apparatus. In order to avoid this, the contact plates 6 have elastically deformable regions 28, which allow further compensation.
- Figure 5 shows the back of the button 5, on which the slide 27 is movably arranged in a horizontal gap 29.
- the hooks 26 encompass the rocker 13 in the area of the brackets 14, 15. With the bolts 16, the rocker 13 is arranged in the bearing points 18 of the housing part 8 and can be pivoted about an axis A.
- the guide elements 25 of the button 5 run in guideways 30 of the housing part 8.
- the housing part 8 also has a guide 31, into which the slide 27 projects.
- the upper latching point, with which the movement of the pushbutton 5 is limited upwards, is defined by the stops 32, which in this position rest against the housing part 7 in a spring-loaded manner near the opening 10.
- a lower locking point 33 is formed in the lower section of the guide 31, which is designed as a heart curve 34.
- the guide groove divides at a point 35 into two grooves running obliquely downwards and away from one another. Both grooves each have a reversal point 36. In this reversal point 36, the two grooves each run inward at an incline of 45 °. Then they rise obliquely upwards and towards each other until they meet at a point, which represents the rest point 33, which is below point 35.
- the slide 27 also slides down in the guide 31. At point 35, the slide 27 in one, in FIG. 5 that the left, groove runs obliquely downward. When the reversal point is reached, the downward movement of the button 5 is stopped.
- the slide 27 is steered inwards by the 45 ° slope of the groove, so that when the button 5 is released, it is located in the portion of the groove which extends to the lower locking point 33.
- the spring 22, which pushes the button 5 upward reliably holds the slide 27 at point 33 between the two inclines, that is to say the rest point.
- the cleaning device 1 is locked in this state.
- the slide 27 is moved downward in one of the two grooves until the downward movement is stopped by the reversal point 36.
- the slider 27 is again deflected by the 45 ° slope, namely to the right and with the release of the button 5 by the user, the slider 27 slides back up in the guide into the upper locking point, which when the stops 32 are put on Housing part 7 is reached.
- the slide 27 is located above the point 35 within the guide 31.
