Abstract
Description
- The present invention relates generally to bottom-mounted slides and methods of manufacturing the slides and, more particularly, to a bottom-mounted slide which is slid by balls which roll between a movable member and a stationary member.
- Generally, bottom-mounted slides are provided between drawers and bodies of, e.g., desks, to enable users to easily open or close the drawers. For example, in the case of a three-stage folding style bottom-mounted slide, a stationary member is fastened to a sidewall or bottom plate of a drawer by an extension. A movable member is fastened to a lower surface of a bottom plate of a desk. Three raceways are formed in each of both lateral sides of an intermediate member. Furthermore, a plurality of balls is located between the stationary member and the intermediate member and between the movable member and the intermediate member. The balls roll along the raceways. Thereby, the intermediate member slides along the stationary member, and the movable member slides along the intermediate member.

FIG. 3 is a sectional view of the bottom-mountedslide 30, according to the embodiment of the present invention.FIG. 4 is a perspective view showing amovable member 35 of the bottom-mountedslide 30 according to the present invention. As shown inFIG. 3 , the bottom-mountedslide 30 includes amovable member 35,stationary members 32 andreception members 34. A plurality offirst raceways 37 is formed on each of both lateral sides of themovable member 35. Eachstationary member 32 has a plurality ofsecond raceways 33 which are respectively connected to thefirst raceways 37 by correspondingballs 39 to guide themovable member 35. Theballs 39 roll between the corresponding first andsecond raceways ball housing 34 is provided between themovable member 35 and the correspondingstationary member 32 and houses theballs 39 therein. In the embodiment, a ball retainer which has a width greater than that of the conventional ball retainer 4 is used as theball housing 34. - In the bottom-mounted
slide 30 of the present invention, a U-shapeddepressed part 40 is provided in a predetermined portion of each end of themovable member 35 between the correspondingfirst raceways 37 such that the interior of themovable member 35 is filled with thedepressed part 40. - Therefore, the bottom-mounted
slide 10 has a wide-width structure such that a horizontal web of themovable member 35 is longer than a lateral web thereof. Furthermore, a proportion of defectives formed by roll-forming can be reduced, and the volume of ahollow space 47 formed in each of the lateral sides of themovable member 35 is minimized by the U-shapeddepressed part 40. Thus, the strength of themovable member 35 can be enhanced so that it can be used to support a comparatively high load. - The
movable member 35 includesraceway parts 45. Eachraceway part 45 includes thefirst raceways 37 which are formed at position corresponding to the correspondingsecond raceways 33 of thestationary member 32. Theraceway part 45 further includeswebs first raceways 37. Thewebs horizontal web 36 and alateral web 38. Thehorizontal web 36 is longer than thelateral web 38. - In the
movable member 35 of the present invention, thedepressed part 40 is formed in thehorizontal web 36. Here, thedepressed part 40 is inserted into thehollow space 47 formed in themovable member 35. - Of course, as shown in
FIG. 3 , it is desirable that thedepressed part 40 have a U-shape which has no portion on which stress is concentrated unlike a V-shaped structure in which stress is concentrated on the lower end thereof. However, the shape of thedepressed part 40 is not limited to this and, in other words, it may have any shape including the V shape, so long as thehollow space 47 is filled with thedepressed part 40. - Furthermore, it is preferable that the
depressed part 40 be aligned with the lateral axis of themovable member 35. - As mentioned above, the bottom-mounted
slide 30 of the present invention is manufactured by roll-forming in the same manner as that of the conventional technique.FIG. 5 is a sectional view showing a process of manufacturing the bottom-mountedslide 30 according to the present invention. In the bottom-mountedslide 30 according to the present invention, thedepressed part 40 is formed in the medial portion of thehorizontal web 36 so that the volume of thehollow space 47 formed in themovable member 35 can be minimized. - In the present invention, the
depressed part 40 is formed in thehorizontal web 36 by a separate process before the movable member 5 is rolled. Thereafter, the other parts of the movable member 5 are formed byrolls 20 and 20' in the same manner as that of the conventional technique. In this case, it was found that the problems, such as defective forming or imprecise measurements, can be avoided unlike the movable member 5 of the conventional technique. The reason for this is that although compression force is applied to thewebs hollow space 47 when the roll-forming process is conducted, thedepressed part 40 withstands and absorbs the compression force. - Furthermore, it was found that when the
depressed part 40 has a U-shape and is aligned with the lateral axis of themovable member 35, thedepressed part 40 can effectively withstand and absorb the compression force applied to thewebs hollow space 47. - As such, the present invention can use the roll-forming method which has been used in the conventional techniques, so that additional expenses are not required. The installation and operation of the
slide 30 of the present invention are the same as those of the conventional techniques, therefore further explanation is deemed unnecessary. - In the case of the conventional wide-width style slide, the raceway part may be easily deformed towards the hollow space of the movable member by horizontal moment during the roll-forming process, so that the shape of the completed raceway part may differ from the original design. Alternatively, although the shape of the completed raceway part is the same as that of the original design, the measurements of the raceway part may not be correct and may fall outside a tolerance range. Such incorrectness in the shape or measurements of the raceway part causes a defective movable member.
- However, in the bottom-mounted
slide 30 of the present invention, thedepressed part 40 formed in thehorizontal web 36 of themovable member 35 effectively withstands and absorbs compression force applied to themovable member 35 towards thehollow space 47. Therefore, despite the fact that bottom-mountedslide 30 has a wide width, it can be prevented from deforming attributable to horizontal moment. Furthermore, the measurements of the manufactured product can be prevented from falling outside a tolerance range. - Below a method of manufacturing the bottom-mounted slide according to the present invention will be described with reference to
FIG. 6 . - First, at step S10, the U-shaped
depressed parts 40 are respectively formed in the predetermined portions of the lateral sides of themovable member 35 such that thehollow spaces 47 formed in the lateral sides of themovable member 35 are filled with the correspondingdepressed parts 40. At step S20, thefirst raceways 37 which come into contact with the rollingballs 39 are formed in the lateral sides of themovable member 35. Step S20 is conducted by the same roll-forming method as that of the conventional technique. As such, thedepressed parts 40 are first formed before thefirst raceways 37 are formed, so that the problems of defective forming or imprecise measurements can be prevented. - Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
- As described above, the present invention provides a bottom-mounted slide which is configured such that a defective proportion of roll-forming can be reduced and the strength thereof can be enhanced so that it can be used to support a comparatively high load.
