Safety device for drawers

Claim 2

A safety device for a drawer of a desk having a panel with an inner wall, said desk having an upper edge to define a compartment for receiving said drawer, said safety device comprising: a mount securely mounted to said inner wall of said panel of said drawer, said mount comprising a vertical portion on which a first track is provided and a horizontal portion in which a hole is formed; a sliding assembly comprising: a body having at least one compartment, a stop being received in one of said one compartments, said stop having an upper operative curvature for guiding said upper edge during a closing movement of said drawer, said upper operative curvature inclining from an end thereof closer to a user to the other end thereof, a stopping surface being defined on said other end, a second track extending longitudinally from said body, a slider slidably received in said second track means, said slider having a second upper operative surface for guiding said upper edge during an opening movement of said drawer, a member projecting from said body and being vertically and slidably received in said first track, a pin extending downward from said body passing said hole and having a means at a distal end thereof to prevent said pin from disengagement with said hole, and a spring means being wound around the pin; a top of said stop and said slider being high above a bottom of said upper edge of said desk when said spring means is in an original uncompressed status, whereby a motion of said drawer is restrained in two positions defined by said stopping surface of said stop and an end of said slider which is adjacent to the user.

Claim 3

The safety device as claimed in claim 1 wherein a sudden rising portion is formed on said second upper operative curvature of said slider adjacent to a peak thereof.

Claim 4

The safety device as claimed in claim 1 wherein said pin has a snapping head at said distal end thereof to allow a removable engagement between said pin and said hole on said mount.

Claim 5

The safety device as claimed in claim 1 wherein said pin is made of flexible material and has a recess formed in a periphery thereof, said sliding assembly being retained when said recess engages with a periphery of said hole.

Claim 6

The safety device as claimed in claim 1 wherein said slider comprises a base plate slidably received in said second track and a ridge projecting upward from the base plate, two stop-pieces extending transversely from a rear of said base plate, said upper operative curvature being formed on said ridge.

Claim 7

A safety device for a drawer of a desk having a panel with an inner wall, said desk having an upper edge to define a compartment for receiving said drawer, said safety device comprising: a mount securely mounted to said inner wall of said panel of said drawer, said mount comprising a vertical portion on which a first track is provided and a horizontal portion in which two holes are formed; a sliding assembly comprising: a body having at least one compartment, a stop being received in one of said one compartments, said stop having an upper operative curvature for guiding said upper edge during a closing movement of said drawer, said upper operative curvature inclining from an end thereof closer to a user to the other end thereof, a stopping surface being defined on said other end, a second track extending longitudinally from said body, a slider slidably received in said second track, said slider having a second upper operative surface for guiding said upper edge during an opening movement of said drawer, a rear member and a side member projecting from said body on of which being vertically and slidably received in said first track, a pin extending downward from said body passing one of said holes and having a means at a distal end thereof to prevent said pin from disengagement with said hole, and a spring means being wound around the pin; a top of said stop and said slider being high above a bottom of said upper edge of said desk when said spring means is in an original uncompressed status, whereby a motion of said drawer is restrained in two positions defined by said stopping surface of said stop and an end of said slider which is adjacent to a user.

Claim 8

A safety device for a drawer of a desk having a panel with an inner wall, said desk having an upper edge to define a compartment for receiving said drawer, said safety device comprising: a mount securely mounted to said inner wall of said panel of said drawer, said mount comprising a vertical portion on which a first track is provided and a horizontal portion in which two holes are formed; a sliding assembly comprising: a body having at least one compartment, a stop being received in one of said one compartments, said stop having an upper operative curvature for guiding said upper edge during a closing movement of said drawer, said upper operative curvature inclining from an end thereof closer to a user to the other end thereof, a stopping surface being defined on said other end, a second track extending longitudinally from said body, a slider slidably received in said second track, said slider having a second upper operative surface for guiding said upper edge during an opening movement of said drawer, a rear member and a side member projecting from said body on of which being vertically and slidably received in said first track, a pin extending downward from said body passing one of said holes and having a means at a distal end thereof to prevent said pin from disengagement with said hole, and a spring means being wound around the pin; a top of said stop and said slider being high above a bottom of said upper edge of said desk when said spring means is in an original uncompressed status, whereby a motion of said drawer is restrained in two positions defined by said stopping surface of said stop and an end of said slider which is adjacent to a user.

Claim 9

The safety device as claimed in claim 6 wherein a sudden rising portion is formed on said second upper operative curvature of said slider adjacent to a peak thereof.

Claim 10

The safety device as claimed in claim 6 wherein said pin has a snapping head at said distal end thereof to allow a removable engagement between said pin and said hole on said mount.

Claim 11

The safety device as claimed in claim 6 wherein said pin is made of flexible material and has a recess formed in a periphery thereof, said sliding assembly being retained when said recess engages with a periphery of said hole.

Claim 12

The safety device as claimed in claim 6 wherein said slider comprises a base plate slidably received in said second track means and a ridge projecting upward from the base plate, two stop-pieces extending transversely from a rear of said base plate, said upper operative curvature being formed on said ridge.
