Abstract

A switch body (2) has first (4) and second (5) rockers to swivel on a rocker axle (6) so as to activate electric contacts. A swiveling locking device affects the operation of the electric contacts and has a locking element (10) that can be adjusted in two or more positions.

Description

The invention relates to an installation switch, in particular universal series installation switch.

Known installation switches, in particular switches for blind drives and the like, turn on or off the necessary for the upward or downward movement of the blind power supply of the associated drive motor. It must be ensured that either only the upward or downward movement of the motor is activated in order not to damage it and to prevent any consequential damage, such as overloading the drive motor or short circuits.

There are already known so-called series switch with an internal, already installed in the factory and inaccessible from the outside lock, in which the supply of only one direction of rotation of the drive motor in a switching operation is possible.

The German utility model DE 297 06 465 U1 discloses a shutter switch, which consists of an electrical series installation switch, which has two switch rockers as standard, is held in a support plate, and which is assembled with a structural unit to form a mechanical lock. This results in the disadvantage that this so changed to a blind switch series installation switch after assembly can only be used as a shutter switch. Another disadvantage is that the assembly to form a mechanical lock consists of several different items for which a corresponding manufacturing, warehousing and assembly device is necessary.

The object of the present invention is to provide an installation switch in which the Vernegelungsfunktion is easy and at any time umstellbar, the number of parts required for this is reduced.

The object is achieved by an installation switch with the features of claim 1. Preferred further embodiments of the invention are specified in the dependent claims.

An advantage of the present invention that even when installing the installation switch in the switch box between a series and a blind switch can be selected. The changing locking of the two paddles is virtually adjustable at the touch of a button. If necessary, this setting can be changed by the installer at any time on site.

A particular advantage is that the locking device is accessible from the operating side of the installation switch forth in a simple manner, so that the installation switch can even remain in its installed state.

In a preferred embodiment, the locking element of the locking device is axially adjustable and rotatably movable. These two degrees of freedom on the one hand in the axial adjustability, the possibility of different positions of the locking element and on the other hand by the rotational mobility creates an advantageous influence on the rockers of the installation switch by the locking element.

The axial adjustability and rotational mobility of the locking element is made possible by means of a receiving element for receiving a central part of the locking element, wherein the receiving element is formed so that the locking element with its central part in this receiving element is axially displaceable and also rotatable simultaneously.

It is advantageous that the locking element has a base body on which the Mitteilteil is arranged as a kind of rotation axis. At the same time, the base body has at its ends a first and a second blocking element and also holding elements. Characterized in that the blocking elements is arranged at the ends of the main body of the locking element, wherein the central part in the arranged in the switch body receiving element is arranged both as a rotation axis and longitudinally displaceable, these two degrees of freedom are also connected to the locking elements. The holding elements serve in a preferred manner to determine the various positions of the axial adjustability of the locking element.

An advantageous embodiment provides that the receiving element is designed for axial displacement of the central part of the locking element along the longitudinal axis of the central part and for rotation of the locking element about the longitudinal axis of the central part, wherein the longitudinal axis of the central part perpendicular to the rocker axis and in the plane of the rocker axis or is arranged in a plane parallel to the rocker axis. This has the particular advantage that the locking element in an already installed switch perpendicular to the rocker axis, which is arranged horizontally, can be inserted from above or from below in a subsequent retrofitting of the installation switch with the locking element in a simple manner. Also pivoting of the locking element about the longitudinal axis of the central part so mounted for influencing the rocker elements is advantageous, since thus no changes to an already existing series installation switch must be made.

The locking element can be adjusted axially in a preferred embodiment of the invention in two positions. One position is the non-functioning condition of the locking element, in which the installation switch fulfills a normal series switch function, i. Both rockers can be actuated independently of each other. In the second position, the locking element is so adjusted axially to the rocker axis that the arranged at the ends of the body locking element are each arranged under a rocker or under a nose arranged at a rocker end. The mutually facing surfaces of each of the locking elements and the ends or lugs of the rockers have corresponding stop surfaces. This results in an advantageous interference-free interaction of the locking element with the rockers.

In a further embodiment, the holding elements for axially fixing the locking element are formed in at least two different positions. This results in advantageous that the above-described positions of the locking element in the axial direction are fixed. In a first position, the locking element is with its locking elements below the rockers and in a second position outside the pivoting range of the rockers.

It is advantageous that the locking element is pivoted in the first position of an actuated rocker on the associated locking element about the longitudinal axis of the central part, wherein the other locking piece is in contact with the associated rocker and forms a coupling with the other rocker when actuated. This results on the one hand, that the locking element requires no return spring or other return means, the second is by this coupling an overlapping of the switching functions that are triggered by the rocker actuation excluded. Because the pressed rocker is reset when pressing the other rocker to its original position, before the former triggers a switching operation.

In a further embodiment, it is advantageous that the switch body has corresponding to the holding elements of the locking element limiting elements. As a result, the definition of the axial adjustment positions of the locking element is advantageously made possible.

It is particularly advantageous that these limiting elements are each arranged on the receiving element. Thus, an advantageous compact design of the locking element with multiple functions is possible.

In a further embodiment, the holding elements are flexible. This offers the advantage that the locking element has many functions with a minimum number of parts.

In a preferred embodiment, the holding elements and the limiting elements each have corresponding first and second spaced-apart holding surfaces for forming the two axial positions of the locking element. This also offers the advantage of the variety of functions within a part, namely the locking element.

It is also advantageous that the locking element has at least one recess and / or starting points for the operation for axial adjustment. Since the locking element is accessible from the front with an installed switch, it is of great advantage that this approach point for example, a tool is also in the front plane, resulting in an advantageous simple and quick changeover of the function of the locking element.

The universal series installation switch according to the invention also has the particular advantage that this series switch can already be provided with the locking element during production, wherein the function of this switch can still be selected and adjusted on site and even when already installed. It is also advantageous if the switch body not only has a receiving element for the locking element, but two opposite. As a result, the position of the locking element can, on the one hand, be adapted to fit the installation site, on the other hand, it is also possible to use a second locking element for special security levels or additional functions such as forced switching. This forced switching is particularly advantageous in shutter switches, as this always an on-position of the switch is made possible, which allow no so-called unlocking a corresponding blind motor, in which both paddles otherwise can remain in the off position. This special function advantageously increases the range of application.

Further advantages of the invention over the prior art result from the fact that the basic components of both types of switches are absolutely identical, that there is no separate production and storage and no additional tool and assembly costs. The shutter switch function can be set locally on the series switch and vice versa.

Further details of the invention are described in the drawings with reference to a schematically illustrated embodiment.

The same reference numerals in the individual figures designate the same or functionally corresponding parts and / or assemblies.

FIG. 1 shows an installation switch 1 in a perspective view. The installation switch 1 consists of a switch body 2 and a known mounting frame 3. Within the switch body 2 are known switching contacts, which are not shown and can be actuated by a first rocker 4 and a second rocker 5 in a known manner.

The installation switch 1 is shown in the non-installed state.

The rockers 4 and 5 are mounted pivotably about a rocker axis 6 on the switch body 2. They are also operated by known actuating surfaces, not shown, also in a known manner by hand. A usual cap of the mounting frame 3 is not shown.

The rockers 4 and 5 are independent of each other about the rocker axis 6 pivotally. Their pivoting movement is limited by their construction and the embodiment of the switch body in a known manner.

Furthermore, the switch body 2 receiving elements 9, 9 ', which are arranged above and below the rockers 4, 5. There may also be only one receiving element 9. The receiving element 9, 9 'serves to receive a locking element 10.

The locking element 10 has a preferably cylindrical central part 11, which is arranged on a base body 14. The locking element 10 is received with the cylindrical central part 11 in the receiving element 9 in a suitable receiving opening.

The locking element 10 is supported by the receiving element 9 so that the locking element 10 on the one hand about the longitudinal axis of the central part 11 is pivotable and on the other hand axially adjustable in the direction of the longitudinal axis of the central part 11.

The receiving element 9, 9 'is arranged so that the storage of the central part 11 takes place so that the longitudinal axis of the central part 11 is arranged at right angles to the rocker axis 6 and in a plane parallel to the rocker axis 6.

Furthermore, the locking element 10 at the ends of its base body 14, a first and a second locking element 12, 13. These locking elements 12, 13 limit the pivotability of the locking element 10 about the longitudinal axis of its central part 11 by interacting with their the switch body 2 facing surfaces with this at certain points.

The surfaces of the locking elements 12, 13 of the locking element 10 opposite these surfaces are designed such that they interact with ends of the rockers 4, 5 or with lugs 7, 8 arranged at these ends in a specific position of the locking element 10.

The axial adjustability of the locking element 10 preferably has two positions. In Figure 1, the position of the locking element 10 is shown, in which this has no function. FIG. 2 shows the locking element 10 in an enlarged representation in this position without function.

The locking element 10 is provided on both sides of the central part 11 with preferably finger-shaped holding parts 16, 16 '. These holding parts 16, 16 'have, at their free ends, which extend parallel to the middle part 11 in the same direction to the center of the switch body 2, on average triangular thickenings. These thickenings each have to the central part 11 indicative beveled surfaces which rest on first corresponding retaining surfaces 21 of limiting elements 17, 17 '. The limiting elements 17, 17 'are arranged on both sides of the receiving element 9, 9' and can be integrally formed therewith.

These first retaining surfaces 21 of the limiting elements 17, 17 'point away from the middle part 11 of the locking element 10 and, together with the retaining elements in this non-illustrated position of the locking element 10, form an axial limit stop. In addition, not shown further means for fixing this position may be provided, for example, suitable thickening on the outer surface of the central part, which cooperate with the opening of the receiving element 9.

A second axial position of the locking element 10 is adjusted by pressing the locking element 10 towards the center of the switch body 2 against the resistance of the flexible holding parts 16, 16 '. The flexible holding parts 16, 16 'are due to the tapered inner surfaces at their ends and the tapered first retaining surfaces 21 to the outside, ie, bent from the central part 11 of the locking element 10, until that they bend back in a second axial position of the locking element 10 below the limiting elements 17, 17 'due to their flexibility back to the central part 11 of the locking element 10 out. Preferably, the holding parts 16, 16 'made of a suitable plastic, which has this elasticity.

In Figure 1 is also shown that between the holding parts 16, 16 ', the central part 11 and the base body 14, a recess 18 is disposed on both sides of the central part 11. This recess 18 serves to return the locking element 10 by means of a suitable tool axially in the first non-functioning position.

If now the function of the switching contact of the rocker 4 for an adjustment, for example, for a blind required, so the rocker 4 is pressed in its upper region (Fig. 1 and 2) down. This has the consequence that the locking element 10, which rests with its first locking element 12 below the nose 7 of the rocker 4, also moves downward by being pivoted about the longitudinal axis of its central portion 11 in a clockwise direction. As a result, this rocker 5 is brought out of its previous switching position at the same time on the voltage applied to the second locking element 13 of the locking element 10 nose 8 of the rocker 5. Thus, the previously switched by the rocker 5 function is turned off by pressing the other rocker 4, so that it can not lead to an overlap of two switching functions.

This described process also applies when first the rocker 4 is actuated.

For this purpose, Figure 4 shows the installation switch 1 in a lateral perspective view, wherein the rocker 5 is actuated. It can also be seen here that the locking element 10 is pivoted about the longitudinal axis of its central part about the receiving element 9 and the limiting elements 17, 17 '.

The locking element 10 may be installed in an advantageous manner always in the installation switch 1. Only by its different axial positions, it is possible in a simple manner to select the function of the installation switch 1. It is of course also possible that the locking element 10 also on site by a plumber also in advantageous simple manner can be attached, or already existing installation switch 1 can be retrofitted.

The above-described axial second position of the locking element 10 is shown in FIG. Furthermore, reference is also made to FIG.

In the second axial position of the locking element 10, the thickenings of the holding parts 16, 16 'are below the limiting elements, wherein they rest with corresponding surfaces on second retaining surfaces 22 of the limiting elements 17, 17'. These second retaining surfaces 22 are arranged, for example, perpendicular to the longitudinal axis of the central part 11 of the locking element 10. This results in an advantageous fixed axial position of the locking element 10th

As Figure 3 shows, the locking elements 12, 13 at the ends of the main body 14 of the locking element 10 in this position of the locking element 10 below the lugs 7, 8 of the rockers 4, 5 are arranged. If now a rocker, for example, the rocker 5 is actuated in its upper portion, i. pressed, the nose 8 of the rocker 5 with the second locking element 13 of the locking element 10 engages and pivots the locking member 10 about the longitudinal axis of the central portion 11 down. Here, the other end of the main body of the locking element 10 is pivoted with the first locking element 12 upwards and engages in engagement with the overlying nose 7 of the other rocker. 4

The locking element 10 is preferably made of a suitable plastic for electrical switching devices. Here, the base body 14 in a preferred embodiment at both ends of bevels 15, which affect the installation of the locking element 10 and also its freedom of movement within the installation switch advantageous. Furthermore, it is preferred that the locking element 10 with its base body 14, the locking elements 12, 13, the Mitteilteil 11 and the holding parts 16, 16 'is made in one piece. Furthermore, it is advantageous that the central part 11 at the end, which is held by the receiving element 9, 9 ', a pin 19 which is smaller in diameter than the central part 11. This pin 19 serves for the advantageous insertion of the locking element 10 in the receiving element 9, 9 '.

The locking element 10 is designed in a preferred embodiment so that the central part 11, the holding parts 16, 16 'and the locking elements 12, 13 of this body 14 all project in a direction parallel to the longitudinal axis of the central part 11.

5 shows a partial sectional view of the rocker 4 with the locking element 10 in the first position in an enlarged view, wherein Figure 6 shows the same view as Figure 5, but with the locking element 10 in the second position. The locking element 10 is shown cut in Figure 5 and 6 in its longitudinal axis through the central part 11 and the pin 19. In this embodiment, the receiving element 9 (also cut) comprises the central part 11 from below with a larger area than from above. Furthermore, the superimposition of the holding surface 21, 22 of the holding part 16 of the Vernegelungselements 10 and the limiting element 17 in the first position and in Figure 6 illustrated in the second position of the locking element 10 is shown in Figure 5. Of course, the nose 7 of the rocker 4 and the stop surface 20 of the locking element may be designed in a different design.

The locking element 10 is shown in Figure 7 for clarity in a perspective view from below, resulting from a view of Figure 1 from an imaginary point behind the plane of the drawing from diagonally below. The main body 11 of the locking element 10 consists in the embodiment shown of a quasi-rectangular, elongated plate which is tapered at its ends from the lower side and having at the ends thickenings, which the first and second blocking element 12, 13 with the stop surfaces 20th , 20 'form. The middle part 11 with the pin 19 is arranged on the upper side of the base body 14, as well as on both sides of this, the holding parts 16, 16 '. All these components 11, 12, 13, 16, 16 '19 extend in the same direction in the direction of the longitudinal axis of the central part 11 of the base plate 14 in different lengths. The locking element 10 is integrally formed with these components 11, 12, 13, 16, 16 '19 together. Of course, other embodiments with Einzelanbringungen or other forms of these parts are possible.

The invention is not limited to the embodiment described above, but modifiable in a variety of ways.

Thus, it is conceivable, for example, that the installation switch 1 has two locking elements 10, wherein these locking elements 10 are attached to opposite receiving elements 9, 9 '.

Furthermore, the flexible finger-shaped holding parts 16, 16 'in cooperation with the limiting elements 17, 17' in a suitable embodiment, a provision of the locking element 10 in a certain initial position cause when the locking element is not pivoted.
