Method of fabricating a chair
View Patent ↗A method of making a chair includes the steps of providing at least one female fastener device. The at least one female fastener device is inserted into a substrate for attaching the at least one female fastener device to the substrate such that at least a portion of that female fastener device's body defining a channel extends into the substrate and the projections extend through the substrate such that the distal ends of the projections extend beyond a second side of the substrate that is opposite a first side of the substrate. The distal ends of the projections are bent into the second side of the substrate. At least one male fastener is inserted into the channel of the at least one female fastener device to attach a chair component to the substrate.
1. A chair comprising:
a base;
a frame attached to the base;
a substrate attached to the frame, the substrate having a first side and a second side opposite the first side;
at least one female fastener device, the at least one female fastener device comprising a body, and a plurality of projections attached to the body, a portion of the body defining a channel sized and configured to receive a male fastener device, each projection of the plurality of projections having a distal end;
the at least one female fastener device positioned in the substrate such that at least a portion of the body defining the channel extends from the first side of the substrate into the substrate and the projections extend through the substrate such that a portion of each of the projections extend into the first side of the substrate and a portion of the projections adjacent to the distal ends of the projections extend beyond the second side of the substrate and wherein the distal ends of the projections are bent into the second side of the substrate; and
at least one male fastener device positioned in the channel of the at least one female fastener device to attach the frame to the substrate, each of the at least one male fastener device being inserted into the channel of a respective one of the at least one female fastener device.
2. The chair of claim 1 wherein the frame is a seat frame.
3. The chair of claim 1 wherein the frame is a back frame.
4. The chair of claim 1 wherein the at least one male fastener device is at least one screw or at least one bolt and the at least one female fastener is at least one T-nut.
5. The chair of claim 4 wherein the distal ends of the projections have barbs defined thereon.
6. The chair of claim 1 wherein the substrate is an upper surface of a seat and the frame is a seat frame.
7. The chair of claim 5 further comprising a cushion that is attached to the substrate.
8. The chair of claim 5 further comprising a seat skin attached to the substrate.
9. The chair of claim 1 wherein the frame is a back frame and the chair further comprises a back skin that is connected to the substrate.
10. The chair of claim 1 wherein the substrate is sized and configured to directly support a back skin, a seat skin, a seat covering or a back covering.
11. The chair of claim 1 wherein the frame is a portion of a seat frame assembly or a portion of a back frame assembly.
12. The chair of claim 1 wherein the substrate is comprised of a polymeric material and the at least one female fastener device is comprised of metal.
13. The chair of claim 1 wherein the distal ends are smashed into the second side of the substrate.
14. The chair of claim 1 wherein threads are formed in the body and at least partially define the channel, the threads sized and configured to engage at least a portion of the at least one male fastener device such that the at least one male fastener device is attachable within the channel.
15. The chair of claim 1 wherein the at least one male fastener device is comprised of a plurality of male fastener devices and the at least one female fastener device is comprised of a plurality of female fastener devices.
16. The chair of claim 1 wherein the first side of the substrate is a top side of the substrate and the second side of the substrate is a bottom side of the substrate.
17. The chair of claim 1 further comprising a covering that covers at least a portion of the substrate.
18. The chair of claim 1 wherein the at least one female fastener device is a unitary structure composed of metal and wherein the body has a first end and a second end, the channel of the body extending from the first end to the second end, the first and second end defining openings that communicate with the channel.
19. The chair of claim 1 wherein the substrate has at least one hole sized and configured to receive at least a portion of the body of the at least one female fastener device and wherein the at least one female fastener device is positioned into the substrate for attaching the at least one female fastener device to the substrate such that the body of each of the at least one female fastener device is inserted into a respective one of the at least one hole.
20. The chair of claim 1 wherein the distal ends of the projections are bent into the second side of the substrate to affix the at least one female fastener device to the substrate to improve a strength of attachment between the substrate and the at least one female fastener device.
