Abstract
A swivel glide is disclosed herein. The swivel glide can include an upper member coupled to a leg of a furniture and a lower member coupled to the upper member via a ball and socket joint. Both the upper member and the lower member are manufactured via injection molding methods. In one example, a cavity side mold and a core side mold can be coupled together prior to injection molding the upper member. Once finished, the molds can be separated and the upper member can be removed from the molds. In another example, the lower member is injection molded and the upper member is injection molded on top of the lower member.
Claims20
A method of manufacturing an upper member a swivel glide, the method comprising:
- providing a first mold, the first mold comprising a first bottom surface, a first top surface, a first cavity, and a spherical protrusion, the spherical protrusion positioned in the first cavity formed on the first top surface, the spherical protrusion comprising a plurality of cutouts formed on an outer surface of the spherical protrusion and extending along at least a portion of a height of the spherical protrusion;
- providing a second mold, the second mold comprising, a second bottom surface, a second top surface, a second cavity, and a plurality of arms;
- positioning the second mold on top of the first mold such that the first top surface of the first mold is abutted against the second bottom surface of the second mold, the plurality of cutouts of the first mold configured to receive the plurality of arms of the second mold when the second mold is positioned on top of the first mold;
- injecting a first moldable material in the first mold and the second mold while the second mold is positioned on top of the first mold;
- curing the first moldable material;
- separating the first mold and the second mold to remove the upper member of the swivel glide.
A method of manufacturing a swivel glide, the method comprising:
- providing a mold having a first cavity for forming a lower member of a swivel glide and a second cavity for forming an upper member of the swivel glide;
- injecting a first moldable material in the first cavity of the mold;
- curing the first moldable material;
- injecting a second moldable material in the second cavity of the mold with the lower member in the first cavity of the first mold;
- curing the second moldable material;
- and
- removing the swivel guide from the first mold, wherein the upper member is coupled to the lower member, wherein upper member is configured to swivel with respect to the lower member.
A swivel glide comprising:
- an upper member configured to couple to a tubular support member of a furniture including a first portion of a ball and socket joint;
- a lower member including a second portion of the ball and socket joint, the ball and socket joint configured for the upper member to swivel with respect to the lower member;
- a base member removably coupled to the lower member, the base member comprising a bottom surface comprising a material different from a material of the lower member.
