BALL-BEARING SLIDE CARRIAGE DEVICE
A ball-bearing slide carriage device comprising (a) a ball-bearing slide carriage which has an inner space and is provided with a plurality of filling slots, buffering open channels located at ends and outside the filling slots and adjoining buffer terminals at outermost ends of the ball-bearing slide carriage and (b) a plurality of balls positioned in the filling slots and used in providing relative sliding effect. As such, the ball-bearing slide carriage depending on the buffering open channels for sliding and stopped at terminal points generates neither noises nor vibrations and features superior buffer quality, quiet effect, durability and fewest troubles.
1. Field of the Invention
The present invention relates to a ball-bearing device, particularly a ball-bearing slide carriage device with balls applied to a slide carriage and characteristic of superior durability, buffer effect, and fewest collision-induced noises.
2. Description of the Related Art
Cabinet lockers or drawers have been extensively applied in various storage implements. To realize a cabinet locker (drawer) which is conveniently pulled out, those slide tracks with functions for positioning and guidance are usually integrated into both laterals of a cabinet locker (drawer). For a cabinet locker (drawer) smoothly and conveniently pulled out or pushed in, a ball-bearing slide carriage which is installed between slide tracks (e.g., inner track and outer track) allows its both ends to be stopped by the inner and outer tracks and is driven in conjunction with the inner track's movement relative to the outer track; the outer track is equipped with a stopper at an outmost end which resists and restricts the ball-bearing slide carriage and prevents it from separation. As shown in
However, the abovementioned ball-bearing slide carriage device which depends on the ball-bearing slide carriage 94 (95) to realize smooth movement generates noises and is regarded as an unideal design failing in quiet effect and product quality for one cabinet locker (drawer) pulled out or pushed in when the sliding ball-bearing slide carriage 94 (95) resists and is stopped by the limiting members. Furthermore, vibrations are observed in the sliding ball-bearing slide carriage 94 (95) which resists and is stopped by the limiting members and evolve into noises due to collisions between the balls 943 (953) and the filling slots 942 (952), 943 (953) which are installed in the ball-bearing slide carriage 94 (95); those noises out of the considerable sum of balls 943 (953) are hardly ignored and required to be overcome. Against this background, it has become a critical issue to correct and get over drawbacks such as noise and vibration in the prior ball-bearing slide carriage in service by persons skilled in the industry.
Accordingly, the inventor having considered an imperfect structural design of the prior ball-bearing slide carriage device in service and attempted to optimize an automatic homing track device with features such as quiet effect, buffering flexibility and durability has studied and developed the present invention for serving the general public and promoting development of the industry.
SUMMARY OF THE INVENTIONThe present invention is intended for providing a ball-bearing slide carriage device, which generates neither noises nor vibrations with the ball-bearing slide carriage stopped at a terminal point and embodies superior buffer quality, quiet effect, durability and fewest troubles, and positively promotes practicability and product quality and competitiveness.
To reach these purposes hereinbefore, the present invention adopts technical measures comprising (a) a ball-bearing slide carriage which has an inner space and is provided with a plurality of filling slots and buffering open channels located at two ends and outside the filling slots and adjoining buffer terminals at outermost ends of the ball-bearing slide carriage; (b) a plurality of balls positioned in the filling slots and used in providing relative sliding effect.
For technical features and effects in terms of the present disclosure completely understood and recognized, the preferred embodiments and detailed drawings are described hereinafter.

Referring to
In an embodiment, the present invention of a ball-bearing slide carriage device is provided with three tracks, that is, the central track 40 (outer track 50) slides and is held in the bottom track 30 (central track 40) wherein the bottom track 30 and the central track 40 (the outer track 50 and the central track 40) relatively slide and construct an unspecific model.
Alternatively, the present invention of a ball-bearing slide carriage device is embodied with a two-track structure whose compositions and motions are not repeatedly explained hereinafter.
The ball-bearing slide carriage 10 and the ball unit 20 can be held between the central track 40 (central track bottom 41) and the bottom track 30 as well as between the outer track 50 and the central track 40 (central track top 42). With the outer track 50 pulled out (
