Abstract
Presented is a slide roller apparatus of elegant simplicity, high precision/cost ratio and few parts where the car/track/rollers are relatively movable and the only needed parts (excepting for attachment means). The car is unitary without end caps for the roller groove, the roller groove being machined or otherwise formed into the car with great precision. The ends of the rollers have a sliding engagement with a rail track surface. The tracks and cars may be made of high precision extruded aluminum hard coated and impregnated with a high lubricity material. The rollers preferably are softer than the tracks and may be made of plastic material. The slide roller apparatus has far ranging applications from sail boats to machine tools.
Claims54
A slide roller bearing apparatus comprising:
- (a) a rail track means having a length for receiving roller means for relative moving engagement there along, said rail track means having a first rail track surface means and a second rail track surface means, each of said first and second rail track surface means having a length and a width,
- (b) a car means operatively associated with said rail track means for movement relative to the length thereof, said car means having a first car surface means and a second car surface means,
- (c) roller means having a length and a diameter disposedly associated with the said rail track means and the said car means to permit rolling movement of said car means relative to the length of said rail means, said roller means having a roller first surface means and a roller second surface means,
- (d) attachment means operatively associated with said car means and said rail means whereby said movement of the car means relative to said rail track means may be usefully employed,
- (e) wherein said roller first surface means is characterized as having a diameter dimension and said roller second surface means is angularly disposed relative to said roller first surface means and said roller second surface means is characterized as having a length dimension of relative size to said diameter dimension when measured on an axis generally transverse to said roller first surface means, said roller first surface means being further characterized as being operatively associated only with said first rail track surface means and with said first car surface means, said roller second surface means being further characterized as being operatively engagable only with said second rail track surface means and said second car surface means.
An apparatus comprising rail track means, car means and plurality of roller means disposed between said rail track means and car means, said rail track means having first and second rail track surfaces disposed at right angles to each other and engagable with said roller means, said car means having first and second car surface means, said first and second car surface means being disposed at right angles to each other, said first car surface means being formed and disposed in spaced parallel relationship to said first rail track surface means, said second car surface means being formed and disposed in spaced parallel relationship to said second rail track surface means, endless U shaped open groove means for receipt of said roller means and formed in said car means, said endless U shaped open groove means having a first side means, a second side means parallel to said first side means, and a base means transverse to and connecting said first and second side means, said base means being formed and disposed in spaced parallel relationship to said first car surface means and said first rail track surface means, said first and second side means of said groove means being formed and disposed in spaced parallel relationship to said second car surface means, said endless groove means having a remote portion located remote from said second car surface means, and a near portion located adjacent to said second car surface means, said near portion being characterized as having at least a portion of said second side means of said groove means removed so that said plurality of roller means when disposed in endless array in said groove means may have at least the portion of the roller means in the said near portion be presented for engagement with said second surface means, each of said roller means being formed with a first surface means and a second surface means transverse to said first surface means and each being disposed in said endless groove means intermediate said car means and said rail means, said apparatus being characterized that when the relative load upon the apparatus is away from said base means and toward said rail first surface means then said first surface of said roller means will be urged by said base means toward engagement with said first rail surface means, and when the relative load on said apparatus is toward said rail second surface and away from said groove means near portion first side means, then said second surface of said roller means is urged toward said second rail surface means by said first side means of said groove means.
