Patent number: 8876231Abstract: An adapter kit of a slide module includes a fixing rack and an external frame coupled with an inner rail and an outer rail respectively and is installed between a drawer and a cabinet. First and second side boards are disposed on both sides of the fixing rack respectively, and the second side board has at least one folded portion and at least one level difference portion. First and second bent portions corresponding to the first and second side boards are disposed on both sides of the external frame respectively, thus the first bent portion and the folded portion can be latched with each other, and an inner surface of the second bent portion abuts the level difference portion to form two support structures to enhance the strength. The adapter kit can be used with various slide modules to provide a hidden slide design and lower the development cost.Type: GrantFiled: March 13, 2013Date of Patent: November 4, 2014Assignee: Martas Precision Slide Co., Ltd.Inventor: Wan-Lai Chen

Patent number: 8220879Abstract: An interlocking device for a slide rail is connected with other interlocking devices through a cable. The interlocking device has a sliding block and a rotary disc disposed on a fixed base. The rotary disc is disposed thereon with a stop block. The sliding block and the stop block are connected with the rotary disc respectively by second springs to link each other. The stop block is connected with a pulley of a slide rail. The sliding block is connected with the cable so that when the slide rail slides outward, the slide rail drives the stop block, the rotary disc, and the sliding block to move synchronously. After the pulley is separated from the stop block, the cable is drawn tightly by the sliding block to lock the other interlocking devices.Type: GrantFiled: January 19, 2010Date of Patent: July 17, 2012Assignee: Martas Precision Slide Co., Ltd.Inventors: Wan-Lai Chen, Tsung-Po Chang

Publication number: 20120068590Abstract: A double-lock structure includes a first module, a second module, a lock, at least one deflecting roller and a transmission element. The first module is installed at an end of a slide rail of each drawer. When one of the drawers is pulled open, other slide rails are linked and locked. The second module is installed on the first module for linking and locking the first module. The lock and the deflecting rollers are installed in a cabinet. An end of the transmission element is connected to the lock, and another end of the transmission element is passed through the deflecting rollers and then connected to the second module. When the lock is operated, the transmission element drives the second module and the first module to perform a drawer interlock to achieve a keylock effect, so as to reduce the manufacturing cost and provide both interlock and keylock functions.Type: ApplicationFiled: September 21, 2010Publication date: March 22, 2012Applicant: MARTAS PRECISION SLIDE CO., LTD.Inventors: Wan-Lai CHEN, Tsung-Po CHANG

Patent number: 7987555Abstract: A hinged slide rail with buffering function, which includes a rail to which a hinge is mounted. The hinge has a movable blade and a fixed blade between which a buffering device is coupled. The buffering device is housed in a retention frame. The retention frame has an end forming a limiting structure. The buffering device has an active rod coupled to the limiting structure. The movable blade includes a pull bar that is connected to the limiting structure. The hinged slide rail is installed between a door panel and a body of a cabinet to remarkably enhance the convenience of operation and eliminates the potential problems of generating noise and clamping and hurting users.Type: GrantFiled: July 3, 2009Date of Patent: August 2, 2011Assignee: Martas Precision Slide Co., Ltd.Inventors: Wan-Lai Chen, Pi-Lan Chen

Publication number: 20080011564Abstract: A damping structure for drawers includes a front portion, a slide portion, a rear portion, at least one spring member and a damping unit. When a user closes a drawer, the push portion of the track presses against the positioning rod, and then the positioning rod is pushed out of the perpendicular slot and is moved backwards due to the restoring force exerted by the two spring members. Now, the fast backward motion of the slide portion may be damped and slowed down due to the damping effect of the damping unit, and hence the drawer may be closed at a reduced speed and in a steady manner.Type: ApplicationFiled: July 11, 2006Publication date: January 17, 2008Inventors: Wan-Lai Chen, Tsung-Po Chang
