Abstract: A drawer interlock mechanism includes at least two drawers, a fixture, a linking frame, locking members and guiding members. The drawers may be pulled in and out. The drawers are lined straight with each other. The fixture is disposed at one side the drawers, and is formed with slots corresponding in position and in number to the guiding members. The linking frame is disposed on the fixture. Each guiding member is secured to the side of each drawer. When one of the drawers is open, the guiding member of the open drawer will link the relative locking member to move the linking frame, which then links the other locking members. The guiding member of the open drawer triggers the relative locking member to lock the linking frame temporarily, and the other locking members block their relative guiding members so that the other drawers are unable to slide.

The guiding switch is locked with the slide at the front. Its side has a guiding groove and a curved groove, which correspondingly match the big column and the small column, so they move according to the path lead by the curved slide groove and the guiding slide groove and the axial cam can rotate 90 degrees.

Abstract: A pull-out safeguard for a drawer cabinet, having a multiplicity of elements (20) which are arranged essentially in a row and can be displaced, a guide means (40) for guiding the elements (20), adjusting elements (50) which are connected to the drawers (12) to be secured, for adjusting the vertical position of the elements (20), and a restricting means (26) for restricting the displaceability of the elements (20). The adjusting elements (50) interact with the drawers (12) to be secured in such a manner that at the beginning of a pull-out movement of one of the drawers (12) to be secured, they move one of the elements (20) and all of the other elements (20) which are situated in one of the directions of the row, but, after a certain pull-out position of the pulled-out drawer (12), are moved back into their starting position by the gravitational force and/or the spring force of a spring element and/or a different driver driving back the elements (20).

Abstract: This invention relates a braking slide structure of the drawer interlock wherein the braking slide is composed of detachable bracket board and the insert sleeve. The bracket board is designed with a guide channel formed by side walls and with the guide stud to limit the bracket board sliding off the bracket. This drawer interlock is mounted on the drawer slides and rails, entailing additional installation of a pair of braking slides. The drawer interlock is an integral element fixed on the drawer for simplified assembly and operation. The braking rod is easy to be inserted into the insert sleeve linking to the top of the bracket board. The bracket board exposes to the outside of the slide hole on the bracket which is easy for the braking rod to slip into the insert sleeve and reach to the top of the bracket board with no space restraint.

Abstract: An improved drawer interlocking mechanism mainly has a number of curved holes at equal angle along the peripheral of an axle hole in the base. There are flexible and moveable sticking tabs along the peripheral of an axle cam, which is allowed to freely rotate when it is installed into the axle hole of a base. After the axle cam rotates by an angle, the tab matches and locks into a curved hole for positioning. Two sets of brakes have symmetrical matching stoppers on two opposite sides, so the brakes can be placed into any slot of the base and a guide groove can be placed on the axle line corresponding to convex point. The groove surface has a stop to block the convex point, so the brake can slide and lead the direction with position limiting function. Thus, this can prevent the brake from dropping out of the slot.

The carriage members slide using the pulling and pushing motions of the activation members when the drawers are opened and closed. Due to the limited space, only one bolt element is insertable between the mobile blocks and only one drawer is openable at a same time.

Abstract: An upright storage cabinet has a lock assembly which operates a vertically movable lock bar to simultaneously lock all drawers of the cabinet. The lock assembly includes a rotatable cam body which has a resiliently deflectable cam that projects radially therefrom. The cam body is rotatable between a locked position wherein the cam rotates a drive element to vertically displace the lock bar into engagement with the drawers, and an unlocked position wherein the cam allows the drive shaft to return to an initial position which disengages the lock bar from the drawers. The cam generates a driving force on the drive shaft during rotation of the cam body and is also resiliently deflectable to accommodate dimensional variations which varies the radial position of the drive shaft relative to the drive element.
