Description of the Invention (1) Field of the Invention The present invention relates to the field of furniture slider assemblies. More specifically, the present invention relates to an improved rotary furniture slide for a leg of furniture articles and a method of making the same. Background of the Invention Furniture slides for fixing to the legs of furniture articles are known to protect the ends of the legs from damage and further protect the floor surface from being damaged by the furniture legs. Traditional furniture sliding parts typically use a plastic bottom surface to contact the floor to allow furniture to slide on the floor surface without over-grinding or scratching the floor surface. In addition, the traditional furniture slide spreads the quality of furniture and any extra mass such as the mass of a person sitting on a chair over a large surface area to prevent dents or imprints from being created on the floor surface. Some furniture sliders also use a rotating mechanism to allow the bottom of the slider to rest flat on the floor surface at a varying angle to the furniture legs. The rotating mechanism compensates for slight changes in the length of the furniture legs, changes in the flatness of the floor surface, and the inclination of the legs of furniture items. SUMMARY OF THE INVENTION Briefly, a preferred form of the present invention is a furniture sliding member comprising a ferrule having an upright cylindrical side wall. Four approximately equally spaced upstanding ribs extend laterally inwardly from the side wall to the guide surface. The diameter of the circle formed by the four guide surfaces is approximately the same as the diameter of the ferrule opening used to receive the furniture leg. The clips positioned in the sleeves have a pair of upright clamp arms. The paper size is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) --------------- ----- Order --------- line (please read the notes on the back before filling this page) 592652 A7 B7 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of Invention (2). A plurality of fork point members extend radially inward from each clamp arm, so that the distance between the fork point members of the first and second clamp arms is smaller than the diameter of the ferrule opening. The slider base on the house slide contacts the floor. The space between the four ribs defines two pairs of oppositely disposed channels, with the clamp arm disposed in one of the two pairs of channels. In a preferred embodiment, each rib extends from the bottom wall of the ferrule to a point adjacent to the opening of the ferrule to provide continuous guidance to the furrow legs when the furrow legs are inserted into the ferrule. '' Each clamp arm has multiple prongs to ensure maximum engagement between the clamp and the furniture leg. The first and second tines are preferably spaced equidistantly from the centerline of the clip, while the third tines are positioned on the centerline of the clip. The third fork-tip pieces are longitudinally spaced above or below the first and second fork-tip pieces to ensure that each fork-tip piece independently engages other furniture-tip sliding pieces. In another embodiment without a clip, at least one prong member extends inwardly from each rib diameter, so that the diameter of the circle formed by the prong member is smaller than the diameter of the ferrule opening. It is an object of the present invention to provide a furniture slide having an improved clip for engaging a furniture leg. Another object of the present invention is to provide a furniture slider having an improved sleeve which facilitates mounting of the slider on the furniture legs. These and other objects of the present invention will be readily apparent from viewing the description and drawings.

The clamp arms 24, 26 extend substantially vertically upward from the clamp base 22. The unstressed clamp arms 2 4, 2 6 define a neutral diameter larger than the diameter 28 of the ferrule opening 18. The clamp arms 2 4, 2 6 of the clamp 10 and the base 22 can be elastically deformed, so when the clamp 10 is inserted into the ferrule opening 18 with the base first, the clamp arms 2 4, 2 6 deform inwardly. To the smaller diameter 2 8 of the ferrule 1 8. The clamp arms 2 4, 2 6 return to a substantially neutral shape after passing through the cuff opening 18. The clip base 22 defines a central clip rivet opening 30. The clamp rivet opening 3 0 is aligned with the ferrule rivet opening 20 when the clamp 10 is installed in the ferrule 12. The clip base 22 is further protruded downward to form a cylindrical portion having a length equal to the contour depth of the dropped portion of the ferrule 12. The rivet openings 20 and 30 have the same diameter. The rivets 3 2 are fixed through the clamps and the ferrule rivet openings 3 0, 20. The rivet 32 has an expandable head 34 and an opposite rotating portion 36 (see Figs. 1 and 2). The head 3 4 of the rivet 3 2 is inserted through the aligned rivet openings 2 0, 3 0 and is pulled round or hammered to reverse the rotating portion 3 6 against the bottom wall 14 of the ferrule 12. The rivet 32 securely fastens the ferrule 12 and the clamp 10 together. The clamp 10 and the ferrule 12 can fully support the furniture legs when riveted together, and therefore preferably do not require any additional structural elements. The rotating part 3 2 of the rivet 3 2 extends downward and radially outward from the bottom wall 1 4 to define a convex spherical external rotating surface and a paper size applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the notes on the back before filling this page) if -------- Order --------- line 丨 t 丨!丨! — Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 592652 A7 B7 V. Description of the invention (7) Concentric inner spherical rotating surface. A shell assembly 38 having an inner shell 40 and an outer shell 42 is slidably engaged with the outer rotating surface of the rivet 32. The inner shell 40 is substantially spherical and defines a circular inner shell opening 4 4 having a diameter smaller than the rotating portion 36 of the rivet 32. The inner shell 40 is nested within the outer shell 42. The housing 42 has a generally frustoconical shape, forming an expanded portion 46 and a reduced portion 48 that define an outer edge. The outer shell 42 defines a circular outer shell opening 50 at the reduced portion 48, which has a diameter smaller than the outer diameter of the inner shell 40. The spherical shape of the inner shell 40 allows the inner shell 40 to have an improved rotational sliding engagement with the outer shell 42. The slider base 5 2 is mounted on the expanded portion 46 of the casing 4 2. The slider base 52 is preferably molded as a unit or a single component. The base 52 is circular and has an annular edge portion 54 for engaging the housing 42 and a central pillar portion 56 which is axially raised (see Figs. 1 and 3). The slider base 52 is mounted in position by bending the outer edges of the housing 42. The post portion 5 6 of the slider base 5 2 defines a substantially convex base rotation surface, which is brought into surface-to-surface contact with the internal rotation surface of the rivet 32. The pillar portion 56 is sized to have a sufficient height to keep the shell assembly 3 8 in tight contact with the rotating portion 36 of the rivet 32. The rotating part 36, the inner shell 40, the outer shell 4 2 and the slider base 5 2 are preferably sized to allow the ferrule 12 to rotate relative to the base 5 2 up to 32 degrees from the plumb line. . For furniture sliding pieces 5 8 which require only a small degree of rotation, only the housing 4 2 is required. The slider base 52 is preferably composed of a hard wear-resistant plastic such as nylon. The slider base 5 2 acts as a cushion pad, and this paper size can be applied to the Chinese National Standard (CNS) A4 specification (210 X 297 mm): Plus-(Please read the precautions on the back before filling this page) Γ Good A -· N ϋ n -ϋ "-, J 1 i__i 1- tmmm ί · ϋ I 1 ϋ ϋ n ϋ n 1 ϋ ϋ n 1 n ϋ I ϋ ϋ ϋ > ϋ I. ^ 1 ϋ ϋ 1 592652 A7 B7 5. Description of the invention (8) Slide along the floor surface. The furniture industry has adopted the standard that the furniture slider 5 8 must be able to withstand a tensile force of 200 pounds before being separated from the furniture legs. U.S. Patent No. 5,991,974 assigned to the assignee of the present case (hereinafter referred to as '97 74 patent) discloses a household slide element similar in many respects to the furniture slide element 58 of the subject matter of the present case. Experiments have shown that the '974 patent device sometimes detached from the furniture leg when a 200-pound pulling force was applied. The devices of the 'Furniture Sliding Elements 5 8' and '9 74' patents used in this case both use a clamping element 10 having a single pair of opposing clamping arms 24, 26. When the furniture leg is inserted into the sleeve 1 2, the furniture leg is forced into between the clamp arms 24, 26 of the clamp member 10, so the clamp arms 24, 26 contact the ferrule 12 by a radially outward force. The side walls 1 6. A single prong member on each clamp arm of the '9 7 4 patented device and a set of prong members 60 on each clamp arm 2 4, 2 6 of the present invention can be sufficiently elastically deformed to be home The outriggers press radially outward and continue to maintain a radially inward force. The radial inward force of the prongs 60 provides a continuous frictional engagement of the prongs 60 to the outer surface of the furniture leg. The engagement of the prongs 60 on the outer surface thus secures the furniture slide to the furniture legs. As mentioned above, the '9 7 4 patented device has only a single prong on each clamp arm. Therefore, if the fork tip member does not have an arc shape that fully matches the arc shape of the surface of the furniture leg, the engaging surface of the fork tip member may not be fully utilized to engage the furniture leg. For example, if the fork tip is too "flat", only the middle portion of the fork tip will engage the furniture leg. Conversely, if the fork tip is too “curved”, only the edge of the fork tip will be connected to this paper. The Chinese standard (CNS) A4 (210 X 297) is applicable.

Description of the invention (9) Family leg. The performance of the prongs becomes this way due to the fact that the contact between any part of the prongs and the furniture legs will cause the entire prongs to deflect radially outward. This radial deflection causes the other parts of the fork tip to move away from the furniture leg. With further reference to FIGS. 4 and 5, each clamp arm 2 4, 2 6 of the present invention includes a set of three separate prongs 60 extending radially inwardly. Each set of fork-tip pieces 60 includes two fork-tip pieces 6 2, 6 4 which are disposed at approximately the same distance Η 1 from the base ′ 2 2 of the clip 10. The fork point member 62 is located on one side of the centerline 66 of the clamp member, and the fork point member 64 is located on the other side of the centerline 66 of the clamp member at a distance substantially the same as the fork point member 62. The third fork point member 68 is located on the center line 66 of the clip member, and at a distance of Η 2 from the base of the clip member, so that it deviates from the fork point members 6 2 and 64 in the vertical direction. As shown in FIGS. 4 and 5, the fork tip members 6 8 can be positioned below the fork tip members 62 and 64. Alternatively, the fork tip members 68 can be positioned above the fork tip members 62 and 64. The engagement surfaces 67 of the prongs 62, 64, 68 define a circle having a diameter 6 9 which is smaller than the diameter 28 of the ferrule opening 18. When the furniture leg contacts any of the fork tip members 62, 64, 68, the contacted fork tip member (for example, the fork tip member 6 2) elastically deforms radially outward. However, this deformation will not be transmitted to the other two fork tip members (64, 68) in the set of fork tip members 60, so that the other fork tip members (64, 68) will move out of contact with the furniture legs. In addition, the spring force exerted by the contacted prongs (6 2) on the prongs 'legs tends to drive the prongs' legs laterally into contact with other prongs (64, 6 8). Therefore, the design of the present invention ensures that there is a gap between the fork tips 6 2, 6 4, 6 8 and the furniture legs.

Description of the invention (1Q) Large joint. As described above, the side wall 16 of the ferrule 12 has a diameter larger than the diameter 28 of the ferrule opening 18 selected to closely fit the outer diameter of the furniture leg. Therefore, space exists between the outer surface of the house leg and the side wall 16 of the ferrule 12. Although the clamping arms 2 4, 2 6 of the clamping member 10 are arranged in this space, the gap between the side edges 70 of the two clamping arms 24, 26 makes most of the gap empty. The furniture leg may be skewed when inserted into the X-ferrule, allowing the furniture leg to enter one of the gaps between the side edges of the clamp arm 70. This can have two harmful effects. First, the portion of the fork tip member engaging the furniture leg may be further reduced when the furniture leg and the furniture slide are skewed relative to each other. Secondly, it has been found that the furniture leg can contact the fork tip in a manner that causes the fork tip to non-elastically deform, thereby reducing the biasing force that holds the furniture slip on the furniture leg. Referring to FIGS. 1, 6, and 7, the side wall 16 of the sleeve 1 12 of the furniture slide 58 of the present invention has four ribs extending longitudinally from the bottom wall 14 to a position point adjacent to the ferrule opening 18. 7 2. Each rib 72 extends laterally from the inner surface 76 of the crotch wall 16 to a distal guide surface 76. The ribs 72 are spaced approximately equidistant from each other such that the guiding surfaces 7 6 of the ribs 72 define a circle having a diameter 7 8 that is approximately equal to the diameter 2 8 of the ferrule opening 18. The clamp arms 24, 26 are located in opposite channels 80 formed between the ribs 72. When the furniture leg is inserted through the ferrule opening 18, the guide surface 76 of the rib 7 2 slides to ensure that the furniture leg cannot be skewed with respect to the axis 8 2 of the furniture slider 5 8. It should be understood that as few as three ribs can be used to properly guide furniture legs during installation. In addition, more than four ribbed paper sizes can be used for China National Standard (CNS) A4 (210 X 297 mm) (please read the note on the back?

Description of the invention (11) In the second embodiment of the present invention (FIGS. 8 and 9), the furniture sliding member 5 8 'includes a ferrule 12 having four ribs 7 2', and the ribs 7 2 from The bottom wall 14 'extends longitudinally to a point adjacent to the ferrule opening 18'. Each rib 7 2 'extends laterally from an inner surface 76 of the ferrule side wall 16' to a distal engaging surface 84. The ribs 7 2 'are spaced approximately equidistant from each other such that the engaging surfaces 8 4 of the ribs 7 2' define a circle having a diameter approximately equal to the diameter of the sleeve. Each of the ribs 7 2 'has at least one prong member 8 6 extending inwardly from the engaging surface 8 4. The prongs 86 define a diameter that is smaller than the ferrule opening 18 '. The prongs 86 can be sufficiently elastically deformed to be pressed radially outward by the furniture legs and continue to maintain a radially inward force. The radially inward force of the tines 86 provides a continuous frictional engagement of the tines 86 to the outer surface of the furniture leg. The engagement of the prongs 86 with the outer surface thus secures the furniture slide 5 8 'to the furniture legs. It should be understood that as few as three ribs and more than four ribs can be used to secure the furniture slide 5 8 ' to the furniture legs. Although the preferred embodiment of the present invention and its manufacturing method have been shown and described in detail, it should be easy to understand that many modifications and changes can be implemented by those skilled in the art. Accordingly, the scope of the accompanying patent application is intended to cover any and all such modifications that fall within the true spirit and scope of the invention.
