Definitions
- the invention relates to an operating device, in particular an operating device for unlocking a locking unit for locking a media unit of a printer in a housing of a tachograph for a motor vehicle, with an operating element, with a front element which has a user-side front and a rear side and with a recess in the front element, in which the control element is arranged movably.
- the invention has for its object to provide an operating device that provides good functional reliability at low cost, high ease of use and that seals off from the environment with the surrounding components.
- the object is achieved by an operating device of the aforementioned type, in which the recess is surrounded by a first contact surface on the front element, 'the operating element having a second contact surface, which faces the first contact face and in a non-actuated position at this abuts and the second contact surface of the control element is clamped against the first contact surface of the recess by means of an elastic element.
- a decisive advantage of the operating device according to the invention lies in the pretensioning of the abutting contact surfaces of the operating element and that which surrounds the recess on the front element by means of the elastic element, so that a permanently defined surface pressure can be structurally adjusted between the two contact surfaces. Since any wear on the contact surfaces, even with an unfavorable choice of material, always moves to an extent that compensation by means of the elastic element is possible without any significant loss of preload force, the tightness of the arrangement is also permanently guaranteed.
- the invention advantageously separates the prestressing function from the sealing function, so that the elastic deformation of the sealing element no longer provides the contact pressure of the seal.
- the arrangement according to the invention advantageously also makes it possible to omit an elastic seal, so that an almost completely wear-free seal from surfaces of medium to high surface quality with a largely non-elastic material brings about the desired sealing effect.
- the invention expediently dispenses with a sealing effect when the operating element of the operating device is actuated, since in the preferred application for unlocking a locking unit of a media unit of a printer in a housing of a tachograph, the tightness requirement is usually only present when the operating element is not actuated.
- Another advantage of the arrangement according to the invention lies in the freedom of movement of the operating element from frictional forces from a sealing arrangement.
- the first contact surface is arranged on the back of the front element.
- the operating element surrounded by a second contact surface corresponding to the first contact surface, this contact surface on the one hand fulfilling the sealing function and on the other hand acting as a retainer or hold-down or stop for the control element.
- the shape of the control element is advantageously coordinated with that of the recess in such a way that the control element can be guided in the recess in the front element.
- the specific design of the control element as a push button is useful if the control element is secured in the recess against rotation by means of a first contouring of the recess and a second contouring of the control element assigned to it.
- the degree of freedom of movement can expediently be reduced with the recess in the front panel, for example to a single translational degree of freedom in the plane of the front panel.
- the first and second contact surfaces can be designed as slide bearings for the slide element.
- control element with a first guide which extends at the rear and which interacts with a corresponding second guide.
- the guiding function can be removed from the front panel and this can be designed to be particularly flat.
- this guide can have a contour in the circumferential direction, so that the operating element cannot be rotated.
- the first and the second contact surfaces can each be conical, so that the two contact surfaces move away from one another when the operating device is actuated, but a certain radial guidance is still ensured.
- the control element of the control device can be designed to be particularly space-saving if the first and second contact surfaces are each flat.
- a spring force of the elastic element which is preferably designed as a spiral spring, of 5 N is sufficient to achieve the desired tightness, a scaled-up essentially proportional scaling would be the same Tightness requirements require an increase in the spring force in accordance with the extent of the circumferential extension of the operating element.
- control element is designed as a push button because the elastic element can be arranged and designed such that when the control element is actuated it exerts a restoring force against the actuation direction on the control element. In this way, the control element always comes into contact with the first and second contact surfaces when it is not actuated and is firmly clamped and arranged there in a sealing manner.
- control element expediently has at least one hold-down device which interacts positively with a hold-down element arranged on the rear of the front element in such a way that, in the absence of the front element, the restoring force from the elastic element on the control element by means of the hold-down device is picked up by the hold-down element.
- the added value of this arrangement lies in the decoupling of the assembly steps of joining the control element and attaching the front element from one another.
- the hold-down element in cooperation with the hold-down device, secures the control element in the pretensioned position.
- the hold-down element can be a separate component, preferably in the form of a flat plate which is provided with a cutout for the operating element, but can also optionally be part of a carrier to which the front element is attached.
- FIG. 1 is a perspective view of a tachograph
- FIG. 9 is a perspective view of a printer with the operating device according to the invention with the front panel installed.
- the front element 10 shown as an individual part in FIG. 2 has a front side 12 facing the user - and a rear side 13 facing away from the user.
- a recess 14 in the spatially flat front element 10 is used to arrange and guide the control element 9.
- the recess 14 has a first cylindrical guide 15 adjoining the recess, in which the control element is guided so as to be movable in the actuating direction 16 with radial play.
- a first contact surface 17 is flat and has an annular shape corresponding to the cylindrical shape of the recess 14.
- the first contact surface 17 of the front element 10 serves the control element 9 as a stop in a non-actuated position, in that an annular second contact surface 18 of the control element 9 shown as an individual part in FIG. 3 on the first contact surface 17 of the front element 10 is present.
- the first contact surface 17 and the second contact surface 18 interact under elastic prestress by means of an elastic element 19 shown in FIG. 5 as a seal against splash water and dirt.
- the rear view of the control element 9 of FIG. 4 shows a guide element 20 which extends in the actuation direction 16 and which has a first contour 21 in the circumferential direction to the actuation direction 16, which has a second contour (not shown) of a corresponding recess (not shown) in the printer 8 in the way cooperates that the control element 9 can not be rotated.
- the guide element 20 acts as an additional axial guide in the actuation direction 16, which prevents the operating element 9 from tilting and limits the degree of freedom to the simple, translatory movement in the actuating direction 16.
- the gear arrangement of the locking unit 11 actuated by the control device 1 essentially has a bolt 23, which is braced against the unlocking device by means of a second elastic element 22, a sliding surface guide 24 with inclined surfaces Sliding surfaces 25, 26 and a slide 27.
- the operating element 9 transmits the operating force as a translatory movement to the slide 27, which, by means of the sliding surface guides 24, 25, transmits this movement to the bolt 23 against the restoring force of the second elastic element 22.
- the user of the operating element 9 must actuate against the restoring forces of the first elastic element 19 and the second elastic element 22.
- the first elastic element 19 is provided in addition to the second elastic element 22.
- the first elastic element 19 has an essentially constant restoring force of approximately 5 N, which the user must apply plus the force from the second elastic element 22 for unlocking.
- the control element 9 is first attached to the printer 8, as shown in FIG. 6, then a hold-down element 30 with a second cutout 31 for the control element 9 is placed over the control element 9, which is in the second cutout 31 Game is agile.
- the hold-down element 30 acts like a wing on the control element 9 radially to the actuation direction 16 protruding hold-downs 33 together, so that the control element 9 is captively attached to a carrier 34 of the printer 8. This fact is also clear from the illustration in FIG. 8.
- FIG. 9 shows the printer 8 with the control device 1 according to the invention and the front element 10 fastened to the carrier 34.
- the front element 10 presses the control element 9 in the actuating direction by means of the first contact surface 17, which lies against the second contact surface 18 16, so that there is always a play of approximately 0.75 mm between the hold-downs 33 of the operating element 9 and the hold-down element 30 in the actuating direction 16.
