Definitions
- the invention relates to an installation device and to a method for mounting this installation device.
- the installation device works with a switching element, in particular a switching handle, the resetting of which is carried out by a torsion spring which is received in a receiving space of the switching element, in detail according to the generic concept of claim 1.
- the spring is supported on the one hand with a spring end on Body of the switching element and on the other hand from deflection of the switching element with a spring end on the body of the installation device or its housing.
- Such torsion springs are usually placed on a mandrel or received by a receiving space; they have to be tightened by a rotary movement during assembly and subsequently adjusted or positioned.
- the invention has for its object an installation
- the described object is achieved by an installation device according to claim 1.
- the receiving space is limited by a jacket of the element body, in particular the control handle, which has a suspension slot for the spring element which is supported on the control handle when deflected forms that a supporting edge 30 is executed starting from a central position upward and downward fleeing or inclined.
- a recessed one At the bottom of the support base for the torsion spring is a recessed one
- the suspension slot On its upper side, the suspension slot has a further suspension pocket for one of the spring ends of the torsion spring after a sector intended for tensioning the torsion spring.
- the torsion spring can then be installed as follows: The torsion spring is inserted into the receiving space and its upper end of the spring is twisted in the additional suspension pocket by a rotary movement. The shape in the suspension slot ensures that the lower end of the spring slides into the suspension pocket assigned to it.
- the switching element forms, together with the torsion spring, a preassembled structural unit which is ready for operation without further adjustment and positioning when inserted into an installation device.
- the length of the upper end of the spring or other designs can be supported at a suitable point on the body of the installation device or its housing when the switching element is deflected by a rotary movement. In the idle state, it is not necessary to attach the upper spring end to the installation device.
- Spring end can also be biased by an inclined contact surface 16 according to FIG 1 in the housing during assembly.
- the suspension slot on the support base of the torsion spring merges into a support surface for one of the spring ends that is formed outside the jacket. This contact surface is increasing. If the spring end is bent back like a hook or can rest on the rising support surface in some other way, the last gear of the torsion spring is bent towards the support base, so that the torsion spring when it is mounted. days can be pulled apart in their individual gears, so that the spring action is not impaired by friction between the individual winding gears.
- the height of the torsion spring is understandably to be matched to the height of the receiving space, the height of the spring increasing somewhat during tensioning.
- the suspension pocket on the top of the suspension slot can simply be designed in the form of a step, over which the upper spring end jumps over after tensioning.
- the spring tension can hereby be predetermined by the angle between the starting position of the spring end and the step.
- the installation device 1 according to FIG 1 is at least provided with a switching element 2, which in the exemplary embodiment as Shift handle is executed.
- the Schaitele ent 2 receives a torsion spring 3, which ensures the return of the switching element after its deflection.
- the torsion spring 3 is inserted in a receiving space 4. In the exemplary embodiment, this is cylindrical and is delimited by a jacket 5 and a central mandrel 6.
- the spring ends 7 and 8 are supported on the body of the switching element 2 or, when the switching element is deflected, on the body of the installation device 1.
- the body of the switching element forms a suspension slot 9 according to FIG. 2, for which spring end 7 is supported on the switching element, here on the switching handle, upon deflection.
- a supporting edge 10 flies upwards and downwards from a central position 11 or inclined. If a torsion spring is inserted and the top end of the spring is deflected counterclockwise in a rotational movement, the bottom end of the spring slides down to a support base 12 for the torsion spring 3 and slides into the recessed hanging pocket 13. On its upper side, the suspension slot 9 forms a further suspension pocket 14 according to FIGS. 1 and 3 after a sector intended for tensioning the torsion spring.
- the middle position 11 of the suspension slot 9 can be selected so that a torsion spring which has not fallen deeply into the receiving space during assembly can slide into the lower suspension pocket 13 with its lower spring end.
- the middle position 11 of the insertion slot 10 can also be chosen so deep that even a torsion spring that falls deeply during assembly is guided with its upper spring end in order to hang the upper spring end into the further suspension pocket 14 solely by a rotary movement can.
- the hanging pocket 14 at the top of the hanging slot 9 can have the form of a step in a simple manner, over which the upper end of the spring can drop during tensioning.
- the suspension slot 9 according to FIG. 2 is provided on the support base 12 of the torsion spring with an increasing support surface 15.
- the support surface 15 can be formed outside the jacket of the receiving space and deflect a spring end bent back like a hook in such a way that the lower winding path of the torsion spring is tilted downward, so that the torsion spring is pulled apart and tensioned between the two suspension pockets 13 and 14 .
- the rising or inclined contact surface 15 also ensures that when the pre-assembled unit consisting of the switching element and the torsion spring is pressed into a receiving installation device, the counterforce on the upper spring end 8 cannot lead to the torsion spring jumping off the switching element. The last turn of the torsion spring is thus pressed against the bottom of the receiving space.
- the support base 12 for the torsion spring can in particular be roughened in order to increase the holding forces for the torsion spring when it is inserted into an installation device.
- FIGS. 4 and 5 The embodiment for a torsion spring 3 according to one exemplary embodiment is illustrated in FIGS. 4 and 5.
