Guide rail mechanism for an article of furniture
A guide rail mechanism includes a fixed rail unit, a movable rail unit slidably mounted on the fixed rail unit, and a tail hook projecting from a top side of the movable rail unit. The tail hook has an upwardly extending section extending upwardly from the movable rail unit, and an insert section extending forwardly from the upwardly extending section and having a taper portion tapered to terminate at a striking tip. The taper portion is deflected from a central line of a width to have the striking tip spaced apart from the central line and at a side away from a fixed wall. An adjusting space is formed when the guide rail mechanism is connected between a furniture carcass and a drawer.
1. A guide rail mechanism connectable between a furniture carcass and a movable furniture part for guiding movement of the movable furniture part relative to the furniture carcass in a front-rear direction, comprising:
a fixed rail unit having a fixed wall which is securely mountable on the furniture carcass;
a movable rail unit slidably mounted on said fixed rail unit in the front-rear direction, and spaced apart from said fixed wall in a left-right direction; and
a tail hook projecting from a top side of a rear end portion of said movable rail unit, said tail hook having an upwardly extending section which extends upwardly from said movable rail unit, and an insert section which extends forwardly from said upwardly extending section to terminate at a striking tip, said insert section being configured to have a largest width portion which connects with said upwardly extending section and which has a largest width of said insert section in the left-right direction, and a taper portion which extends and is gradually tapered from said largest width portion to said striking tip, said taper portion being deflected from a central line which extends in the front-rear direction and through a center of said largest width portion to form said striking tip spaced apart from the central line and at a side of the central line away from said fixed wall, said taper portion having a longer bevel edge which extends from a side edge of said largest width portion over the central line, and a shorter bevel edge which extends from an opposite side edge of said largest width portion toward the central line, which connects with said longer bevel edge at said striking tip and which has a length shorter than said longer bevel edge, said longer bevel edge being disposed between said shorter bevel edge and said fixed wall.
2. The guide rail mechanism as claimed in claim 1 , wherein said longer bevel edge has a bevel angle toward the central line which is different from that of said shorter bevel edge.
