Definitions

• Conventional lift-sliding elements such as lift-sliding doors, can have a considerable weight of up to 400 kg or more. This can result in a correspondingly large amount of force being required to set the sliding sash of such a lift-sliding door in motion, as is the case, for example, when opening the lift-sliding door from its closed position.
• Once the sash of such a lift-sliding door has been set in motion it exhibits a considerable amount of kinetic energy due to its weight. This can lead to the sliding sash hitting the frame when reaching the closed position when closing such a lift-sliding door. This can lead to damage to the lift-sliding door, especially at higher impact speeds.
• the same problem also arises when fully opening such a a lift-sliding door, as the sliding sash can also hit the frame when it reaches the open position.
• the invention is therefore based on the object of providing a device with which a lifting-sliding element can be opened with only little effort and which at the same time enables a gentle closing of the lifting-sliding element.
• This object is achieved with a device having the features of claim 1 for assisting the closing and opening of a lift-and-slide element such as a lift-and-slide door or a lift-and-slide window.
• the device according to the invention for assisting the closing and opening of a lift-and-slide element comprises a base body designed for attachment to a sash frame of a lift-and-slide element.
• Two axially extending prestressing elements are hinged to the base body, so that they do not have to be mounted individually on the sash frame of the lift-and-slide element.
• the device has an axially extending first prestressing element, such as a first gas pressure spring, which has a first end and a second end that is hinged to the base body.
• the device has an axially extending second prestressing element, such as a second gas pressure spring, which has a first end and a second end that is hinged to the base body.
• the device has a switching mechanism which can be switched between a first limit switching position and a second limit switching position and which is slidably mounted on the base body and secured there against lifting forces. If, for example, the switching mechanism is transferred from its first limit switching position to its second limit switching position, the switching mechanism cannot move beyond the second limit switching position. The same applies to a switching process of the switching mechanism starting from its second limit switching position towards its first limit switching position, in which the switching mechanism cannot be moved beyond its first limit switching position.
• the switching mechanism has an L-shaped angled switching element, which is also referred to here as an angle element and which in turn can be pivoted between the two limit switching positions.
• the switching mechanism serves as a coupling link between the two preload elements, since the first end of the first preload element is coupled to the first end of the second preload element via the switching mechanism under a preload of the first and/or second preload element. Regardless of the position or deflection of the two preload elements, they are thus always interacting with each other, since one preload element applies a preload force to the other preload element via the switching mechanism, and vice versa.
• the switching mechanism is designed in such a way that it has only a single unstable equilibrium position between its two end switching positions.
• the two preload elements are therefore only aligned with each other in the unstable equilibrium position in question and are thus axially aligned. Beyond or outside the unstable equilibrium position of the switching mechanism, however, the two preload elements are not axially aligned with each other, which means that only the force component of one preload element that acts in the direction of the axial extension of the other preload element interacts with it. For example, If the second pre-tensioning element is deflected relative to the first pre-tensioning element, only that force component which is aligned with the first pre-tensioning element is transferred from the second pre-tensioning element to the first pre-tensioning element.
• the second prestressing element is deflected relative to the first prestressing element, which is more compressed than the second prestressing element, then in this position the prestressing force exerted by the first prestressing element is always greater than the force component of the second prestressing element acting in the direction of the first prestressing element.
• the first prestressing element in the first end switching position of the switching mechanism, urges the lifting/sliding element towards its closed position against the prestressing force of the second prestressing element when the first end of the first prestressing element is supported on a fixed or stationary abutment.
• the second pre-tensioning element can urge the lifting-sliding element towards its opening position against the pre-tensioning force of the first pre-tensioning element if the first end of the second pre-tensioning element is supported on a fixed or stationary abutment.
• an opening impulse can be applied manually to the sliding sash 14, as shown in the first illustration of the Fig. 5 by the arrow pointing to the left.
• the second gas pressure spring 56 can thus move according to the transition from the third representation of the Fig. 5 to the first presentation of the Fig. 6 expand and thereby support themselves on the abutment 60 with the result that the sliding sash 14 is opened automatically after the opening impulse has been received.
• the first gas pressure spring 54 thus urges the sliding wing 14 toward its closed position against the pretensioning force of the second gas pressure spring 56, whereas in the second end switching position of the angle element 70, the second gas pressure spring 56 urges the sliding wing 14 of the lifting-sliding element 10 toward its open position against the pretensioning force of the first gas pressure spring 54.
• a first stop (not shown in detail here) can be formed on the first leg 72 of the angle element 70, against which the first gas pressure spring engages in the first limit position.
• a second stop (not shown in detail here) can be formed on the second leg 74 of the angle element 70, against which the second gas pressure spring 56 engages in the second limit position.
• the device 50 can also have an actuating mechanism with which the switching mechanism 58, and in particular its angle element 70, interacts, at least in the closed position of the lifting/sliding element, in such a way that when the sliding sash 14 of the lifting/sliding element 10 is lowered, the angle element 70 is moved from its first limit position to its second limit position.
• the angle element 70 can be positively coupled to the gear of the lifting/sliding element 10, by means of which the sliding sash 14 can be raised and lowered, in such a way that when the sliding sash 14 is lowered, the angle element 70 is moved into its second limit position.
