Patent number: 10973323Abstract: A securing device (1) for securing a front panel of a drawer to a drawer frame, having a holding element (2) for securing to the front panel and a closing element (3) for securing to the drawer frame. A spring (44) is operatively connected to the closure (50). The closure (50) is implemented for exposing a holding region of the holding element (2) in an open rotational position of the closure (50), and for blocking the holding region in a closed position of the closure (50). A transmission element (60) is hinged to the closure by a rotating/sliding connection on the closure side spaced apart from the rotary axis of the closure. A rotating/sliding connection on the opener side having a first bearing element (64) is disposed on the transmission element (60) opposite the rotating/sliding connection on the closure side. The rotating/sliding connection on the opener side produces a connection to a displaceably supported opener (70).Type: GrantFiled: May 8, 2018Date of Patent: April 13, 2021Assignee: Samet Kalip Ve Maden Esya San.

Patent number: 10799024Abstract: A securing device is provided for securing a front panel of a drawer to a drawer frame, having a holding element for securing to the front panel and a closing element for securing to the drawer frame, the closing element comprising a support and a closure having a holding segment supported rotatably about an axis of rotation on the support, a spring having an operative connection to the closure, and the closure being implemented for releasing a holding region of the holding element in an open rotational position of the closure, and for blocking the holding region in a closed position of the closure. It is thereby provided that a transmission element is joined to the closure by a rotating/sliding connection on the closure side spaced apart from the rotary axis of the closure, that the rotating/sliding connection on the closure side includes a first and a second guide curve, and that the two guide curves intersect.Type: GrantFiled: May 9, 2017Date of Patent: October 13, 2020Assignee: Samet Kalip Ve Maden Esya San.

Patent number: 8474926Abstract: A fully extendable telescopic drawer guide for furniture components that can be extended from the body of an item of furniture, with a guide rail facing the body, a running rail associated with the extendable furniture component, and an intermediate rail arranged between these two rails. Rolling elements are provided which are supported in cages and transfer the load of the extendable furniture component by way of rolling surfaces disposed on the rails. At least one rotatably supported supporting roller for the running rail is provided on the front end of the intermediate rail. The intermediate rail is implemented as a profile rail which encompasses the region of the guide rail provided with the rolling surfaces and which has on the bottom side an elongated opening for insertion of the support region of the guide rail to be secured to the body wall of an associated item of furniture.Type: GrantFiled: June 30, 2010Date of Patent: July 2, 2013Assignee: Alfit AGInventor: Christian Prentner

Publication number: 20090243451Abstract: A pull-out guide for drawers comprises a carcass rail, a central rail mounted displaceably in relation to the latter, and a pull-out rail mounted displaceably in relation to the central rail. The movement of the central rail is synchronized by a control roller. The control roller with a hard body and a soft body is mounted on a spindle which is elliptical in cross section.Type: ApplicationFiled: December 23, 2004Publication date: October 1, 2009Inventors: Christian Prentner, Gunter Grabher

Patent number: 7399041Abstract: A drawer pull-out guide including an automatic retraction device having a pawl component with a receptacle that receives a catch on a running rail as the rails move relative to the guide rail when approaching a closed position and an entraining rocker. During a final part of retraction movement of the pawl component, the entraining rocker being coupled to and movable with the pawl component; and during an initial displacement path of the pawl component the entraining rocker being decoupled from the pawl component and retained against longitudinal displacement in the pawl housing. A first spring biasing the pawl component into a first end position and locking the pawl component; and a second spring for biasing the entraining rocker in a direction of retraction engages on the entraining rocker.Type: GrantFiled: July 28, 2004Date of Patent: July 15, 2008Assignee: Alfit AGInventors: Christian Prentner, Guenter Grabher

Patent number: 7396092Abstract: Pull-out guide (10) for furniture parts with a running rail (14) fixable to a furniture part and a carcass rail (12) fixable on the furniture carcass as well as and a central rail (16) which is provided between these two rails. The rails are guided so as to be longitudinally displaceable relative to one another by load-transmitting anti-friction bearings which are in each case retained rotatably in cages (22). The anti-friction bearings are constructed in a manner known per se as cylindrical rollers (30; 34) which are retained in the associated cage (22) so as to be rotatable transversely with respect to the pull-out direction about a horizontal or vertical as in each case, and which can roll on elongate planar tracks constructed on the respectively associated rails.Type: GrantFiled: June 20, 2003Date of Patent: July 8, 2008Assignee: Alfit AGInventors: Christian Prentner, Günter Grabher
