Actuating element
View Patent ↗An actuating element for controlling an electronic device is providing. The actuating element including a front cover having an actuating surface to be actuated by a user and a support structure adapted to be coupled to the front cover. The support structure having guiding rips that guide the movement of the actuating element in a housing upon actuation of the actuating element. The front cover having centering shoulders that contact the guiding rips for positioning the support structure relative to the front cover when the front cover is coupled to the support structure.
1. An actuating element for controlling an electronic device, comprising:
a support structure having at least one surface extending from a first end to a second end to form a support structure housing having at least one guiding rip projecting lengthwise from the at least one surface and a first fixing structure;
a front cover having a second fixing structure and centering shoulders for contacting the guiding rip for positioning the support structure housing relative to the front cover when the front cover is coupled to the first end of the support structure by engaging the first fixing structure on the support structure to the second fixing structure on the front cover, the front cover and support structure being fixedly engaged to move as a unit during actuation.
2. The actuating element of claim 1 , where the guiding rip has an upper, lower and side surface and where each of the centering shoulders contacts a different surface of the guiding rip.
3. The actuating element of claim 1 , where the support structure has two opposing side surfaces and one guiding rip is positioned on each of the opposing side surfaces.
4. The actuating clement of claim 1 , where two groups of centering shoulders are provided on the front cover, one group of centering shoulders positioned to engage one guiding rip and the other group of centering shoulders positioned to engage the other guiding rip.
5. The actuating element of claim 1 , where each centering shoulder further includes a projecting rip provided on a surface of the centering shoulder that contacts the guiding rip.
6. The actuating element of claim 1 , where the centering shoulders includes a group of at least three centering shoulders and where two centering shoulders of in the group of centering shoulders limit the movement of the support structure relative to the cover in a first direction, whereas a third centering shoulder of the group of centering shoulders limits the movement of the support structure relative to the cover in a second direction substantially perpendicular to the first direction.
7. The actuating element of claim 1 , where the front cover has a back surface and an actuating surface and where the centering shoulders project from a back surface of the front cover.
8. The actuating element of claim 1 , where the centering shoulders includes a group of centering shoulders and where at least one of the centering shoulders are extends substantially parallel to a side surface of the support structure from which the guiding rip extends and at least one centering shoulder extends substantially perpendicular to said side surface.
9. The actuating element according to claim 1 , where the first fixing structure includes a projection on the support structure and the second fixing structure includes a recess on the centering shoulder where the recess of the centering shoulder engages the projection on the support structure when securing the front cover to the support structure.
