Definitions
- the invention relates to a pressure switch unit of the type specified in the preamble of claim 1.
- Corresponding pressure switch units include a push button and a guide element for the push button.
- the push button can be pressed by the user in relation to the fixed guide element.
- the pressure switch unit can be designed as on / off switch or as a push button.
- Push button and guide element are provided to form a linear guide with guide surfaces, which slide on each other during the Eindgurvorgang. The guide surfaces are in contact with each other in such a way that they allow a push-in movement of the push button relative to the guide element in the Eindschreibraum and prevent a relative movement of the push button relative to the guide element.
- a pressure switch unit is known for example from DE 10 2004 061 950 A1.
- the present invention has the object, a pressure switch unit of the type mentioned in the preamble of claim 1 in such a way that an improved leadership of their push button is achieved.
- At least one elastically resilient spring element is arranged, which exerts a biasing force between the push button and the guide element transversely to the indentation.
- the elastic spring element significantly improves the positionally accurate centering of the push button relative to the guide element due to its biasing force.
- the push button may be appropriate to provide only one spring element or a plurality of such spring elements.
- two are provided with respect to a surface axis of the base of the push button opposite spring elements, wherein the biasing forces of the two spring elements are directed opposite.
- the push button With the same geometric design of the two spring elements and in the same amount of biasing forces the push button centered exactly centered, without unbalances, tilting and unwanted friction points with neighboring components arise.
- an embodiment of the push button with an elongated base which has a short surface axis and a long surface axis
- an embodiment has been found to be expedient in which the two spring elements are opposite in the direction of the long surface axis.
- the arranged along the long surface axis spring elements have by their large distance from each other a particularly pronounced balancing effect.
- the spring element may for example be designed as a helical spring and be hung with both ends on the one hand on the push button and on the other hand on the guide element.
- the spring element is arranged either on the push button or on the guide element, while a linear guide for a sliding guide of the prestressed spring element is arranged on the respective adjacent guide element or push button. In this way it can be ensured that the design-dictated preload force is kept constant independently of the Eindgurweg of the push button.
- the linear guide is formed as a groove, in which engages a sliding projection of the spring element.
- the engagement of the sliding projection in the groove creates a positive connection not only in the direction of the biasing force, but also across it.
- an elastically yielding position centering of the push button is also brought about transversely to the direction of the biasing force, that is, in total, in all directions perpendicular to the indentation direction.
- the groove has a prismatic cross-section, while the sliding projection which engages in this prismatic cross section and abuts there is rounded. As a result, a smooth sliding behavior is effected despite the acting biasing force.
- the spring element is designed as a spring tongue and in particular designed in one piece with either the push button or the guide element.
- the spring tongue is elastic not only in the direction of its intended preload force, but also transversely thereto. giebig so that they can exert the desired centering effect on the push button in both directions.
- FIG. 1 is a perspective sectional view of an inventively executed pressure switch unit with guide element, push button, guide surfaces and guided in grooves, prestressed spring elements,
- Fig. 2 is an interior view of the push button of FIG. 1 with details for
- FIG. 3 shows a front view of the guide element according to FIG. 1 with details for forming the guide surfaces and the spring elements arranged on the guide element, FIG.
- FIG. 4 shows a perspective detailed view of the guide element according to FIG.
- Fig. 1 shows in a perspective sectional view of a pressure switch unit according to the invention for actuating an electrical contact in a motor vehicle.
- electromechanical unit of the push button 1 can be used either as a switch with two different switch positions or as a button.
- the pressure switch unit comprises a push button 1 and a guide element 2 for the push button.
- the push button 1 is shown for better clarity in the sectional view shown without its recognizable in Fig. 2 top surface 12, so that only one central guide web 13 and an outer border are visible from the push button 1.
- the push button 1 is linearly pressed against the fixed guide member 2 by the user in a Eindschreibraum 5.
- For the leadership of the push button 1 in this indentation 5 are shown on the push button 1 in Fig. 2 formed first guide surfaces 3 and the guide element 2 in Fig. 3 illustrated second guide surfaces 4.
- Fig. 2 shows in a frontal interior view of the push button 1 of FIG. 1 with details of its geometric configuration.
- the lying here in the plane of the base of the push button 1 can be configured circular, square or in any other form and has two mutually perpendicular surface axes 7, 8, which in turn are perpendicular to the indentation 5 (Fig.
- the push button 1 has an elongated base with a short surface axis 7 and a long surface axis 8, wherein the base is rectangular with rounded corners. But it can also be provided an oval, elliptical or any other base.
- the push button 1 is in the form of an open shell with a top surface 12, formed with two opposite side walls 14 and two opposite end walls 15, in which case the user facing away from the inside of the top surface 12 can be seen.
- the side walls 14 and the end walls 15 form a frame surrounding the top surface 12.
- guide web 13 is formed centrally.
- a total of six first guide surfaces 3 are formed on the guide web 13, which are arranged partially parallel to the short surface axis 7 and partially parallel to the long surface axis 8, but in each case parallel to the indentation direction 5 (FIG.
- At least one linear guide in this case two linear guides 9 for spring elements 6 described in more detail below in connection with FIGS. 3 and 4, are arranged on the pushbutton 1 and formed integrally with the pushbutton 1 as a plastic injection-molded part.
- the two linear guides 9 lie on the long surface axis 8 and are positioned symmetrically opposite one another with respect to the short surface axis 7 lying perpendicular thereto.
- Fig. 3 shows a front view of the guide element 2 of FIG. 1, which is in the form of a circumferential frame.
- the two surface axes 7, 8 of the pushbutton 1 according to FIG. 2 are projected onto the guide element 2 for better orientation.
- a plurality of, here exactly six second guide surfaces 4 are formed, which are the six first guide surfaces 3 of the push button 1 (Fig. 2) correspond, and apply to the spatial position of the same information as to the first guide surfaces 3.
- At the guide element 2 at least one elastically resilient spring element 6 is arranged.
- a total of two such spring elements 6 are provided, which lie relative to one of the two surface axes 7, 8, here relative to the short surface axis 7 as the axis of symmetry in the direction of the long surface axis 8, and which thereby corresponds to the linear guides 9 of Push button 1 of FIG. 2 on the long surface axis 8 are located.
- Fig. 4 shows in a perspective detail view of the guide element 2 of FIG. 3 in the region of one of its two spring elements 6.
- the spring element 6 is formed as a spring tongue, at its free end outwardly projecting a rounded sliding projection 1 1 is formed.
- the spring element 6 projects in the region of its sliding projection 1 1 outwardly beyond the basic contour of the guide element 2. Starting from this unloaded position, the sliding projection 1 1 can be pressed elastically yielding into a receiving pocket 17 of the guide element main body to produce a biasing force.
- the spring element 6 may consist of spring steel or the like and is molded in the embodiment shown in one piece with the main body of the guide element 2 made of plastic.
- biasing forces F act perpendicular to the indentation 5 and therefore have no direct influence on a push-in movement of the push-button 1 in this indentation 5.
- FIG. 1 The illustration according to FIG. 1 can furthermore be seen that the first guide surfaces 3 shown in FIG. 2 and the second guide surfaces 4 shown in FIG. 3 abut each other flatly and with a minimal play in the assembled state.
- the guide surfaces 3, 4 By the above-defined spatial position of the guide surfaces 3, 4, they produce a sliding guide of the push button 1 on the guide element 2 in the Eindgurraum 5, while all other spatial degrees of freedom are prevented. Divergent relative movements are possible only within the framework of the constructively provided minimum game.
- the respective linear guides 9, which are in the form of a groove 10 have a prismatic cross-section with flat sliding surfaces, which are here by way of example V-shaped.
- the spring elements 6 engage with their rounded sliding projections 1 1 positively in this cross section and are biased to the sliding surfaces of the groove 10 at.
- a sliding relative movement of the spring elements 6, namely their sliding projections 1 1 relative to the linear guides 9 in the Eindrückraum 5 while maintaining the acting biasing forces F allowed while in all perpendicular thereto spatial directions, ie in particular in the direction of the short surface axis 7 or perpendicular to the acting biasing forces F is a positive connection.
- the spring elements 6 are elastically yielding and despite the existing play between the guide surfaces 3, 4 to a centering of the push button 1 perpendicular to the direction of the biasing forces 4, ie in the direction of the short surface axis 7, as indicated by double arrows 19 is.
