Abstract
A method of forming a table top comprises providing a skin-support frame, forming a lower skin portion of the table top, forming an upper skin portion of the table top such that the upper skin portion has a visual characteristic different from a visual characteristic of the lower skin portion.
Description
- This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application Ser. No. 60/743,423, filed Mar. 7, 2006, which is expressly incorporated by reference herein.
- The present disclosure relates to a table top, and particularly to a process for forming a table top.
- According to the present disclosure, a method of forming a table top comprises the steps of providing a skin-support frame, forming a lower skin portion of the table top, forming an upper skin portion of the table top such that the upper skin portion has a visual characteristic different from a visual characteristic of the lower skin portion, and positioning the upper skin portion and lower skin portion relative to each other so as to provide an interior region containing the skin-support frame. Illustratively, the visual characteristic is a color so that the upper skin portion has a first color and the lower skin portion has a second color different from the first color. In other examples, the visual characteristic may be in the form of a different texture, wood grain pattern, or the like.
- Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of the following detailed description of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.
- The detailed description particularly refers to the accompanying figures in which:
-
FIG. 1 is a diagrammatic view of a table top including an upper skin and a lower skin cooperating with the upper skin to form an interior region containing a skin-support frame during one step of the present process; -
FIG. 2 is a diagrammatic view of a skin-formation system in accordance with the present disclosure for forming the upper and lower skins; -
FIG. 3 is a sectional view showing another table top in accordance with the present disclosure, which table top includes an upper skin or preform adapted to be fitted onto and coupled to a lower skin of a sub-assembly of the table top; -
FIG. 4 is a sectional view similar toFIG. 3 showing the upper skin coupled to the lower skin such that a side wall of the upper skin overlaps and mates against a side wall of the lower skin to define a partition or parting line therebetween exposing a lower portion (i.e., “reveal”) of the side wall of the lower skin and showing that the exposed lower portion of the lower skin side wall has a second characteristic that is different from and in contrast with a first characteristic of the side wall of the upper skin; -
FIG. 5 is a sectional view (similar toFIG. 4 ) of another table top in accordance with the present disclosure showing a parting line of the table top ofFIG. 4 raised (as compared to the parting line shown inFIG. 3 ) to expose a larger portion (i.e., reveal) of the side wall of the lower skin; and -
FIGS. 6 and 7 are sectional views of two more table tops having upper and lower skins with different characteristics. - A
table top 10 includes a tabletop skin unit 12 enclosing aframe 14 oftable top 10, as shown, for example, diagrammatically inFIG. 1 .Skin unit 12 includes anupper skin 16 having a first characteristic 18. Alower skin 20 ofskin unit 12 has a second characteristic 22 different from the first characteristic 18. Illustratively, first characteristic 18 is a first color and second characteristic 22 is a second color different from the first color. In other examples, first and second characteristics 18, 22 may be different textures, wood grain patterns, or the like. As such, characteristics 18, 22 may be different colors, textures, wood grain patterns, or any combination thereof -
Upper skin 16 includes a top surface 17 and anedge surface 19. As suggested inFIG. 1 ,upper skin 16 is coupled tolower skin 20 to formtable top 10.Edge surface 19 is arranged to peripherally surround top surface 17 to form aninterior region 21 therebetween. -
Lower skin 20 includes abottom surface 15 and anedge surface 29. As suggested inFIG. 1 ,lower skin 20 is coupled toupper skin 16 to formtable top 10.Edge surface 29 is arranged to peripherallysurround bottom surface 15 to forminterior region 21 therebetween. -
Table top 10 is formed by positioning upper andlower skins edge surface frame 14 to lie ininterior region 21. After the positioning of upper andlower skins upper skin 16 tolower skin 20 completes the process. - A skin-
formation system 24 in accordance with the present disclosure may be used to form eachskin FIG. 2 .System 24 comprises astrip extruder 26 that extrudes astrip 28 of plastics material (e.g., ABS—acrylonitrile butadiene styrene).System 24 may include acolorant dispenser 30 for adding a color to strip 28 to provide a visual thereof. In some examples,system 24 may have afilm applicator 32 arranged to apply on a surface of strip 28 a thin film having a predetermined pattern, such as, for example, a wood grain pattern or otherwise, to provide a visual characteristic thereon. - Cooling rollers, strip movers, and any number of other strip-treatment devices may be included in
system 24. For example,system 24 may be configured to coordinate the constant output ofextruder 26 with the “batch” processing of a shape former 34 (e.g., a thermoformer or a vacuum former) downstream fromextruder 26 relative to movement ofstrip 28. In other examples,system 24 may have a strip cutter (not shown) arranged to cutstrip 28 into individual sheets to be subsequently fed to shape former 34. - Shape former 34 is configured to form
strip 28 or individual sheets thereof into the desired shape for therespective skin skin - A single shape former 34 may be used for each
skin skins skin skins multiple shape formers 34 may be used to formskins - As suggested above, shape former 34 may be, for example, a thermoformer or a vacuum former. In the case of a thermoformer, the thermoformer is configured to
thermoform strip 28 or sheets thereof into the desired shape by use of heat and mechanical pressure. In the case of a vacuum former, the vacuum former is configured to formstrip 28 or sheets thereof into the desired shape by use of heat and vacuum pressure. - Shape former 34 may be configured in any number of other ways to form
skins skins - A trimmer (not shown) may be included in
system 24 downstream from shape former 34. In such a case, the trimmer is used to trim excess material fromskins -
Table top 10 is assembled after formation ofskins frame 14 and, in some cases, a core associated withframe 14 are placed onlower skin 20. In cases where there is a core,frame 14 extends along a periphery oflower skin 20 adjacent toedge surface 29 and the core is placed withinframe 14.Upper skin 16 is then coupled tolower skin 20 to retain frame 14 (and an associated core) ininterior region 21 formed betweenskins - A
table top 110 includes askin unit 112 having anupper skin 116 and alower skin 120, as shown, for example, inFIGS. 3 and 4 .Upper skin 116 has first characteristic 18 andlower skin 120 has second characteristic 22 different from first characteristic 18, 22. Illustratively, first characteristic IS ofupper skin 116 may be a color, as suggested by acolorant 127 added toupper skin 116, or may be afilm 125 applied to a surface ofupper skin 116. In other examples, first characteristic 18 may be a texture applied toupper skin 116. -
Lower skin 120 is formed of a plastics material (e.g., ABS) surrounding a core 126 (e.g., honeycomb or corrugated). Atubular frame 114 may extend along aperiphery 130 oflower skin 120 to peripherally surround core 126.Lower skin 120 may be formed by use ofextruder 26 in combination with a die (not show) to produce the cross-section oflower skin 120. End caps (not shown) or other closures may be added to the ends oflower skin 120 to close the ends thereof.
