  • Patent number: 6464311
    Abstract: A slide comprises an outer member, an intermediate member, and an inner member. The intermediate member is held in place when slide is fully pulled out to a locked out position. A lock and release mechanism for the slide comprises a flexible strip having a proximal end attached to the intermediate member and a distal end slantingly extended. A fork at the end of flexible strip is lowered to be locked by a stop member on the outer member as the intermediate member is extended to the locked out position by the removing inner member. Hence, the intermediate member is held in the locked out position. The flexible strip has a trigger member capable of lifting together with the fork to disengage from the stop member as retracting the inner member, thereby unlocking the intermediate member.

  • Patent number: 6457790
    Abstract: A release mechanism for telescoping slide assembly including an outer member and an inner member is provided. The mechanism comprises a flexible strip of substantially triangular transverse cross section mounted on the inner member, the flexible strip including two flexible arms each extended from either end of a bottom plate thereof, two opposite recesses, and two locking lugs on the sides of either recess; and an engagement section on outer end of intermediate member, the section including an aperture and a projection on the edge of aperture. In the use position, the locking lugs contact the inner wall of the intermediate member while sliding, and the recesses are clung to both sides of the projection when the inner member has reached a predetermined end of the use position, thus blocking movement of the inner member relative to the intermediate member. Moreover, either arm may be depressed to disengage recess from projection. Hence, inner member may be moved away from outer member or retract inner member.

  • Publication number: 20020089274
    Abstract: A release mechanism for telescoping slide including an outer member and an inner member is provided. The mechanism comprises an elongate connection member slidably mounted on the inner member. Operation performed on the access end of connection member at outer end of the slide may be transmitted to a pivot member near inner end of the slide. Thus pivot member may be selectively locked or unlocked for stopping or enabling the relative movement of the inner and the outer members. The push-pull style manipulation of the connection member is advantageous for having the open access end. Further, the structure is simplified for facilitating manufacture.
