Description
Technical field
The present invention relates to a kind of installation constitution of sliding rail assembly, particularly relate to one kind can be used for being quick installed at a cabinet with
Sliding rail assembly between one drawer.
Background technology
U.S. patent Nos U.S.5 disclosed in Maberry et al., 457,867, which discloses one kind and utilizes cylinder
（rollers24,40）For the sliding rail assembly of slip vehicle, comprising a cabinet component（cabinet member14）, and one take out
Drawer component（drawer member38）Be slidably connected the cabinet component（cabinet member14）.During assembling, with a pair
Bushing（bushings16,18）And a pair of screws（screws20A,20B）By the cabinet component（cabinet member14）Lock
Gu to a cabinet wallboard（cabinet panel12）Upper positioning, and the drawer member of arranging in pairs or groups（drawer member38）Locking exists
One drawer（drawer36）Side.Thereby, the drawer（drawer36）Can be with the drawer member（drawer
member38）Be slidably connected the cabinet component（cabinet member14）, make the drawer（drawer36）With respect to the cabinet
Wallboard（cabinet panel12）It is easy to slide displacement.
Employing cylinder disclosed in above-mentioned Maberry et al.（rollers24,40）The sliding rail assembly of form, due to can be with
Allow drawer（drawer36）And cabinet wallboard（cabinet panel12）Than larger assembling tolerance, therefore, for furniture system
For making dealer, drawer is produced（drawer36）And cabinet wallboard（cabinet panel12）Assembling precision just need not be as
It is accurate as same industry, so, this employing cylinder（rollers24,40）The sliding rail assembly of form is widely employed to be in
In tool industry.However, cylinder（rollers）The sliding rail assembly of form has the restriction carried in loading, and, also because allowing public affairs
Poor factor, so that this sliding rail assembly is difficult design and combines buffering recurrence（soft-closing）Or it is press-started（push-
open）Etc. function, to increase its surcharge.
U.S. patent Nos U.S.5 disclosed in Cabrales et al., 895,101, its announcement adopts steel ball（ball
bearings）As the sliding rail assembly of slip vehicle, as this ball guide has precision high and to carry loading relative
Higher advantage, and gradually it is subject to consumers.Furthermore, this ball guide can also select additional cushion to return（soft-
closing）Function, the U.S. patent Nos U.S.6 as disclosed in Kim et al., 712,435B2.However, as ball guide has
There is the characteristic that precision is high, so that when the assembling tolerance between the drawer and cabinet produced by furniture manufacturer exceedes ball guide
Acceptable tolerance when, ball guide is subject to the extruding between drawer and cabinet, can cause having some setbacks for drawer slide displacement on the contrary
Freely.
U.S. patent Nos publication U.S.2013/0106271A1 disclosed in Anderson et al., a kind of its steel of announcement
Pearl slide rail, comprising an at least fixture（fixed member56）Laterally it is fixedly mounted in a drawer sliding rail, and at least
One floating part（floating member54）Laterally slide in the fixture（fixed member56）, set with such
Meter, makes this ball guide also allow there is larger assembling tolerance between drawer and cabinet.
However, the design disclosed in aforementioned Anderson et al., once floating part（floating member54）Quality
Itself is bad, and such as tolerance is excessive or damaged, the floating part（floating member54）May be from the fixture（fixed
member56）There is the anxiety for coming off, and, once the floating part（floating member54）From the fixture（fixed
member56）Come off, at this of whole group ball guide, installation site loses and original allows there is larger between drawer and cabinet
Assembling tolerance.
