Universal Energy Accumulator
A door operator, including a housing, a drive element for storing closing and opening energy for a door leaf, and a drive unit, including at least one piston, which unit can be coupled to the door leaf, where the drive element comprises at least one elastically deformable element, which is disposed on a push rod which is in operative connection with the piston.
1 . A door operator, comprising a housing, a drive element for storing closing and opening energy for a door leaf, and a drive unit, including at least one piston, which can be coupled to the door leaf, wherein the drive element comprises at least one elastically deformable element, which is disposed on a push rod, which is in operative connection with the piston.
2 . The door operator according to claim 1 , wherein the elastically deformable element abuts, at least in sections, at the housing.
3 . The door operator according to claim 1 , wherein the elastically deformable element is rubber-elastically deformable.
4 . The door operator according to claim 1 , wherein the elastically deformable element can be manufactured from materials comprising at least one of plastic materials, elastomers, rubbers, caoutchuc or silicone rubber or a combination of the materials of plastic materials, elastomers, rubbers, caoutchuc or silicone rubber.
5 . The door operator according to claim 1 , wherein the elastically deformable element is disposed in a sleeve.
6 . The door operator according to claim 5 , wherein the sleeve, at least in sections, is a part of the housing.
7 . The door operator according to claim 5 , wherein the sleeve is disposed in an opening of the housing.
8 . The door operator according to claim 5 , wherein the sleeve can be manufactured from a plastic material.
9 . The door operator according to claim 1 , wherein the push rod is configured as a single part or in multiple parts.
10 . The door operator according to claim 1 , wherein the push rod includes at least one groove or recess, at which at least the elastically deformable element can be disposed in the centre.
11 . The door operator according to claim 10 , wherein the elastically deformable element is vulcanized and/or glued into the groove or the recess.
12 . The door operator according to claim 1 , wherein the elastically deformable element is configured in a ring-shape.
13 . The door operator according to claim 1 , wherein the push rod is movable in the direction of a longitudinal extension and the elastically deformable element can be deformed by the movement of the push rod.
14 . The door operator according to claim 1 having at least two elastically deformable elements, wherein the elastically deformable elements are spaced apart from each other by means of at least one spacer sleeve.
15 . The door operator according to claim 14 , wherein the elastically deformable element can be, at least partially, non-positively and/or positively brought into engagement with the spacer sleeve.
16 . The door operator according to claim 15 , wherein the engagement is realized such that the elastically deformable element, at least in sections, abuts at the spacer sleeve.
17 . The door operator according to claim 1 , wherein the spacer sleeve and the elastically deformable element surround a spacer element, which is disposed on the push rod and/or which is configured integrally with the push rod, and/or which, in the longitudinal extension of the push rod, can be arranged like a cascade with at least one other spacer element.
18 . A kit, including elastically deformable elements and/or at least one spacer sleeve, in particular one elastically deformable element and/or one spacer sleeve according to claim 1 , for composing a drive element having adjustable spring characteristics.
