Description
- The present invention relates to a slide rail assembly and more particularly to a slide rail assembly having two slide rails which are simultaneously displaceable.
-
US Patent Nos. 6,997,529 B and7,413,269 B2, both granted to Chen et al. , disclose a slide rail assembly featuring simultaneous displacement of two slide rails and are referenced when the present invention was made.US 2007/0164644A discloses a further example of a slide rail assembly. As two simultaneously displaceable slide rails provide better support, a slide rail assembly having such slide rails can withstand a higher load and is therefore well received on the market. The present invention aims to provide an improved version of such a slide rail assembly. - The present invention relates to a slide rail assembly having two slide rails which can be displaced simultaneously.
- According to one aspect of the present invention, a slide rail assembly includes a first rail; a second rail slidably connected to the first rail, the second rail having an opening; a third rail slidably connected to the second rail; a guiding base provided on the first rail, the guiding base having a pair of guiding portions and a stop portion, the guiding portions defining a guiding path and a guiding entrance in communication with the guiding path; a first contact member provided on the second rail, the first contact member including a pair of first contact portions and a pair of second contact portions connected to the first contact portions, wherein the second contact portions extend through the opening of the second rail and correspond to the guiding entrance of the guiding base; and a second contact member provided on the third rail, the second contact member having at least one lateral portion corresponding to one of the first contact portions of the first contact member. The guiding path of the guiding base has a first width, the guiding entrance of the guiding base has a second width, and the second contact portions of the first contact member define a third width therebetween, wherein the third width is greater than the first width but less than the second width. When the third rail is pulled out from a retracted position relative to the second rail, the lateral portion of the second contact member is pressed against the corresponding one of the first contact portions of the first contact member such that the second rail is displaced simultaneously with the third rail by means of the first contact member. Once the second rail is displaced to a predetermined position relative to the first rail, the first contact member abuts against the guiding base, and the second contact portions of the first contact member are guided by the guiding path of the guiding base. Consequently, with the first contact portions of the first contact member displaced toward each other, the lateral portion of the second contact member separates from the corresponding one of the first contact portions of the first contact member, allowing the third rail to be pulled out and displaced relative to the second rail.
- Preferably, the slide rail assembly further includes a fixing base fixed to the first rail. The fixing base has a pair of arms which define a clamping space therebetween, and the second contact member has a projection corresponding to the clamping space. When in the retracted position, the projection of the second contact member extends into the clamping space and is clamped by the arms of the fixing base.
- Preferably, the second contact member has a pair of the aforesaid lateral portions which correspond respectively to the first contact portions of the first contact member.
- Preferably, the lateral portions of the second contact member have inner surfaces facing each other and defining a fourth width therebetween, and the first contact portions of the first contact member have outer surfaces facing away from each other and defining a fifth width therebetween, wherein the fifth width is slightly greater than the fourth width.

As shown inFIG. 2 , theguiding base 18 has a pair of longitudinal guidingportions 44 and astop portion 46. The longitudinal guidingportions 44 define a guidingpath 48 and a guidingentrance 50 in communication with the guidingpath 48. Each of the longitudinal guidingportions 44 has asurface 52 which is located in the guidingpath 48 and the guidingentrance 50. More specifically, thesurfaces 52 of the longitudinal guidingportions 44 that are located in the guidingpath 48 define a first width W1 therebetween, and thesurfaces 52 of the longitudinal guidingportions 44 that are located at the guidingentrance 50 define a second width W2 therebetween. - As shown in
FIG. 3 , thefirst contact member 20 is provided on thesidewall 34 of thesecond rail 12. Thefirst contact member 20 includes a pair offirst contact portions 54 and a pair ofsecond contact portions 56 which are connected to thefirst contact portions 54. Thesecond contact portions 56 extend through theopening 38 of thesecond rail 12. Referring back toFIG. 2 , thesecond contact portions 56 correspond to the guidingentrance 50 of the guidingbase 18. In one preferred embodiment, thefirst contact portions 54 form a V shape, thesecond contact portions 56 havesurfaces 58 which face away from each other, and thesurfaces 58 define a third width W3 therebetween, wherein the third width W3 is greater than the first width W1 of the guidingpath 48 of the guidingbase 18 but less than the second width W2 at the guidingentrance 50 of the guidingbase 18. Preferably, each of thesecond contact portions 56 has aninclined surface 57 corresponding to the guidingentrance 50 of the guidingbase 18 so that the guidingbase 18 can guide thesecond contact portions 56 with ease. - As shown in
FIG. 1 , thesecond contact member 22 is provided on thethird rail 14. Thesecond contact member 22 includes a pair oflateral portions 60 and aprojection 62. Thelateral portions 60 correspond to thefirst contact portions 54 of thefirst contact member 20 respectively while theprojection 62 corresponds to the clampingspace 42 of the fixingbase 16. Preferably, as shown inFIG. 4 , thelateral portions 60 haveinner surfaces 61 which face each other, and theinner surfaces 61 define a fourth width W4 therebetween. Also preferably, as shown inFIG. 5 , thefirst contact portions 54 of thefirst contact member 20 haveouter surfaces 55 which face away from each other, and theouter surfaces 55 define a fifth width W5 therebetween, wherein the fifth width W5 is slightly greater than the fourth width W4. - In
FIG. 6 , the slide rail assembly in one embodiment of the present invention is in a retracted state, in which thesecond contact member 22 is located between thefirst contact member 20 and the fixingbase 16, and theprojection 62 of thesecond contact member 22 is inserted in the clampingspace 42 of the fixingbase 16. With thearms 40 of the fixingbase 16 clamping theprojection 62 of thesecond contact member 22, the slide rail assembly is kept in the retracted state, and thethird rail 14 is prevented from sliding outward even when tilted. - In
FIG. 7 andFIG. 8a , thethird rail 14 has been pulled out relative to thefirst rail 10. More specifically, a portion of thethird rail 14 has been pulled out beyond thefront end 30a of thefirst rail 10. In consequence, thesecond contact member 22 is released from the clampingspace 42 of the fixingbase 16. At the same time, thelateral portions 60 of thesecond contact member 22 are pressed against thefirst contact member 20 due to the fact that the fifth width W5 is slightly greater than the fourth width W4. Therefore, as thethird rail 14 is pulled out, thesecond rail 12 is simultaneously displaced with thethird rail 14. - In
FIG. 8b , thefirst contact member 20, against which thesecond contact member 22 is pressed, has been displaced to the guidingbase 18, with thesecond contact portions 56 of thefirst contact member 20 partially entering the guidingentrance 50 of the guidingbase 18. As the third width W3 between thesecond contact portions 56 is greater than the first width W1 of the guidingpath 48 of the guidingbase 18 but less than the second width W2 at the guidingentrance 50 of the guiding base 18 (seeFIG. 2 andFIG. 3 ), thefirst contact member 20, once pushed and displaced by thesecond contact member 22 to a predetermined position, enters the guidingpath 48 of the guidingbase 18 through the guidingentrance 50 of the guidingbase 18, as shown inFIG. 9a . Meanwhile, thesecond contact portions 56 of thefirst contact member 20 are guided by the guidingpath 48 of the guidingbase 18 and compressed toward each other, and in consequence, thefirst contact portions 54 of thefirst contact member 20 are also compressed toward each other. In this compressed state as shown inFIG. 9b , theouter surfaces 55 of thefirst contact portions 54 of thefirst contact member 20 define a sixth width W6 therebetween, and the sixth width W6 is less than or at least equal to the fourth width W4. - The
third rail 14 is continuously pulled out as shown inFIG. 9c, Fig. 9d andFIG. 10 . Since the sixth width W6 is less than or at least equal to the fourth width W4, thesecond contact member 22 is able to move past thefirst contact member 20 and thus thelateral portions 60 of thesecond contact member 22 are no longer in contact with thefirst contact portions 54 of thefirst contact member 20. As a result, thesecond rail 12 ceases to be pulled along with thethird rail 14 and stays at the guidingbase 18, thanks to thefirst contact member 20. Thesecond rail 12 stops as soon as it is extended to this position. Thethird rail 14 in this state, however, can be continuously pulled out relative to thesecond rail 12. Preferably, with continuously pulled out relative to thesecond rail 12, thethird rail 14 is eventually brought into driving engagement with thesecond rail 12 in the same way as the conventional slide rails, driving thesecond rail 12 to move again. In this way, thesecond rail 12 reaches its farthest extended position relative to thefirst rail 10 when thesecond contact portions 56 of thefirst contact member 20 are pressed against thestop portion 46 of the guidingbase 18. - The
third rail 14 when retracted from an extended position relative to thefirst rail 10 is displaced relative to thesecond rail 12. The displacement of thethird rail 14 relative to thesecond rail 12 will eventually cause thesecond contact member 22 to move past thefirst contact member 20, as shown inFIG. 11 . Afterward, thethird rail 14 will be brought into driving engagement with thesecond rail 12 in the same way as the conventional slide rails, allowing thesecond rail 12 to be pushed relative to thefirst rail 10, and thefirst contact member 20 will separate from the guidingbase 18 in due course. Once thethird rail 14 and thesecond rail 12 are fully retracted relative to thefirst rail 10, the slide rail assembly resumes the retracted state shown inFIG. 6 . - While the present invention has been disclosed by way of the foregoing preferred embodiments, the embodiments are not intended to restrict the scope of the present invention. The scope of the present invention is defined only by the appended claims.
