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.
Claims7
A method of manufacturing at least a portion of 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 to fill the first cavity and the second mold to fill the second cavity while the second mold is positioned on top of the first mold;
- curing the first moldable material within the first mold and the second mold;
- after curing the first moldable material, separating the first mold and the second mold to remove a cured first moldable material from the first mold and the second mold, the cured first moldable material forming an upper member of the swivel glide.
