This invention relates to countertop molds for forming top and edge portions (“overhangs”) of countertops that extend outside the periphery of a cabinet substrate. The countertops are fabricated from a deformable countertop material poured upon the cabinet substrate and into the mold, whereupon, the deformable material solidifies and the reusable mold is removed from the solidified material. In particular, the present invention relates to a reusable countertop mold having multiple brackets that are removably secured to a rail portion of a cabinet member and form members detachably secured to the brackets, thereby allowing the mold to be separated from the rail portion of the cabinet member and solidified countertop material without damage to the rail portion and solidified countertop material extending outside the periphery of the cabinet substrate; whereupon, the separated mold is reused at another job site.
Mold assemblies for forming edge portions of custom countertops when pouring a countertop forming material into a recess formed by a countertop substrate and a mold assembly are well known. In particular, U.S. Pat. No. 7,001,558 (“558”) provides a mold for producing a finished countertop on top of a countertop substrate having a top and an edge. The mold assembly of the 558 patent includes a configured inner surface portion that that receives a countertop forming material. The 558 mold assembly further includes a tab portion extending from the configured inner surface portion, the tab portion dimensioned to extend sufficiently to cover an edge portion and top portion of the countertop substrate, thereby positioning the inner surface of the mold assembly adjacent to the countertop substrate edge to ultimately form a countertop edge after a countertop forming material, engaging the mold assembly, sets or otherwise hardens. After the countertop forming material hardens, the configured inner surface portion is separated from the tab portion, which remains in place between the poured countertop and the countertop substrate.
The problem with the 558 patent is that the mold assembly cannot be reused with the same tap portion described in the patent. More specifically, once the inner surface portion is cut, sawed or otherwise separated from the tab portion, there is no tab portion to extend over the substrate top and edge to hold the inner surface portion adjacent to the countertop substrate edge. In the event that the inner surface portion of the mold assembly includes decorative designs or configurations that result in a relatively expensive mold assembly, once the inner surface portion is separated from the tab portion, the inner surface portion has only salvage value.
In application US 2019-0337196A1 published Nov. 7, 2019, a reusable counter mold is disclosed having a relatively rigid sheet with a continuously extending vertical portion integrally joined to a continuously extending horizontal base portion that horizontally inserts between a top edge portion of a cabinet and a bottom edge portion of a countertop substrate. The base portion includes recesses for enabling fasteners to insert through the countertop substrate, through the recesses and into the cabinet without engaging the base portion.
The problem with the published application disclosing a reusable mold is that the continuously extending mold is relatively difficult to extract from between the cabinet and the countertop substrate after a deformable material has solidified upon the substrate and the reusable mold. Another problem with the published reusable mold is that each side of the substrate to be covered with deformable material must have a continuously extending mold having the same length as the length of the substrate side to which the mold is removably secured, thereby preventing “side lines” in the deformable material. Thus, each side of the substrate requires a corresponding section of reusable mold cut to a predetermined length, resulting in the precut reusable mold section having limited reuse with another countertop forming project.
A need exists for a reusable mold assembly that includes multiple brackets that support a form member, whereby, both the brackets and form member are removed from the solidified deformable material without using a force that would damage the solidified deformable material or the reusable countertop mold.
It is an object of the present invention to provide a reusable countertop mold for forming a finished countertop on peripheral portions of a substrate that is secured to a floor mounted cabinet. A principal object of the present invention is to provide a reusable countertop mold removably secured to a rail portion of a cabinet member. A feature of the reusable countertop mold is multiple brackets removably secured to the rail portion of a cabinet member. Another feature of the reusable counter mold is a form member detachable secured to the multiple brackets. An advantage of the reusable countertop mold is that each of the multiple brackets are secured to a rail portion the cabinet member without damage to the rail portion. Another advantage of the reusable countertop mold is that the form member is cut or otherwise sized to required longitudinal and lateral dimensions at the location of a substrate selected to receive a deformable material, whereby, the deformable material covers the substrate and the sized base portion to ultimately form a solidified countertop that extends past the periphery of the substrate to form an overhang having a configuration corresponding to the reusable countertop mold.
Another object of the present invention is to provide a reusable countertop mold that includes a bracket member having integrally joined vertical and horizontal members that receive corresponding and detachably joined vertical and horizontal form members. A feature of the reusable mold is horizontal and vertical form members that are detachable joined to the bracket member. Another feature of the mold is that the horizontal and vertical form members can be cut at the site of the substrate to provide exact dimensions for the form relative to the dimensions of the substrate. An advantage of the mold is that the horizontal and vertical form members ultimately configure an overhang that compliments the countertop formed on the substrate.
Another object of the present invention is to provide a reusable countertop mold having a bracket member that includes a channel member that receives a bottom portion of a rail portion of a cabinet member. A feature of the channel member is a threaded aperture for rotationally receiving a locking bolt that inserts into the channel member, whereby, the locking bolt detachably secures the position of the channel member upon the rail portion of the support member. An advantage of the channel member is that the channel member is capable of receiving a myriad of rail portions having varying lateral dimensions, resulting in the reusable mold being reused for a myriad of projects.
Yet another object of the present invention is to provide a reusable countertop mold having a bracket member that includes a locking bolt with a boot portion that is rotationally secured to the locking bolt. A feature of the boot portion is a rubber portion that ultimately engages an inner wall of the rail member of the support member. An advantage of the rubber portion is that the rubber portion prevents damage to an inner wall of the rail portion when the locking bolt secures the channel member of the bracket member to the rail member.
Still another object of the present invention is to provide a reusable countertop mold having a relatively rigid offset member. A feature of the offset member is that the offset member is disposed between an outer wall of the rail member and an inner wall of the channel member. An advantage of the offset member is that the offset member prevents damage to outer wall of the rail member when the locking bolt secures the channel member to the rail portion.
Another object of the present invention is to provide a reusable countertop mold having a modified bracket member slidably secured between the substrate and the rail portion of the support member. A feature of the slidably secured modified bracket member is a sliding portion that is urged between the substrate and the rail portion of the support member. An advantage of the sliding portion is that a locking bolt is not required to secure the modified bracket member to the rail portion.
Another feature of the modified bracket member is at least one recess in the sliding portion that promotes the insertion of the fasteners through a substrate portion and into a cabinet member without engaging the sliding portion of the modified bracket member. Still another feature of the modified bracket member is that the recess includes a triangular configuration with a base dimension of the triangle having a length relatively longer than the diameter of the fasteners with the base of the recess being disposed at an inner edge of the sliding portion. An advantage of the sliding portion is that a locking bolt is not required to secure the modified bracket member to the rail portion. Another advantage of the sliding portion is that the triangular configured recesses provide sufficient error tolerance and guidance for the sliding portion in the event that the alignment between the recesses and corresponding fasteners is difficult to maintain as the sliding portion is forcibly urged between the substrate and the rail portion.
The foregoing invention and its advantages may be readily appreciated from the following detailed description of the preferred embodiment, when read in conjunction with the accompanying drawings in which:
Referring now to
The rigid vertical and horizontal form members 226 and 228 can be fabricated from wood, polymers and similar materials capable of being cut to dimensions that enable the form members 226 and 228 to be secured to the bracket members 210 and to encase the perimeter of the substrate 206. The surfaces of the form members 226 and 228 are substantially planar to prevent a relatively high viscosity (“thick”) deformable material from “leaking” between engaging surfaces of the form members 226 and 228, between engaging surfaces of the horizontal form member 228 and an outer wall 244 of the rail portion 212. When a deformable material having a relatively low viscosity (“thin”) is disposed upon the form members 226 and 228, a gasket material fabricated from soft rubber can be disposed between the engaging surfaces to prevent the deformable material from seeping between the engaging surfaces. Further, the surfaces of the form member 226 and 228 engaging the deformable material can be modified, via methods well known to those of ordinary skill in the art, to include a configuration or design required to configure a corresponding surface of the deformable material engaging a respective surface of the form members 226 and 228. When the form members 226 and 228 are removed from the solidified deformable material, a configuration or design is permanently included in the corresponding surface of the overhang portion 220 of the countertop 202 that engaged the form members 226 and/or 228.
Each bracket member 210 includes a vertical plate or sheet member 222 (“vertical member”) integrally joined to a horizontal plate or sheet member 224 (“horizontal member”) that receive corresponding and detachably joined vertical and horizontal form members 226 and 228. Each bracket member 210 further includes a channel member 230 integrally joined to the horizontal member 224. The channel member 230 includes a gap defined by the distance separating two inner walls 246 and 247, whereby, the distance of separation is sufficient to enable the channel member 230 to receive a myriad of rail portions 212 having varying lateral dimensions, thereby allowing the reusable countertop mold 200 to be reusable for a myriad of cabinet members 214 well known to those of ordinary skill in the art. The channel member 230 further includes a threaded aperture 232 for rotationally receiving a locking bolt 234 that inserts into the channel member 230, whereby, the locking bolt 234 detachably secures the position of the channel member 230 upon the rail portion 212 of the cabinet member 214 for the substrate 204 that receives deformable material.
The locking bolt 234 includes a boot portion 236 that is rotationally secured to the locking bolt 234. The boot portion 236 includes a rubber portion 238 permanently secure to the boot portion 236 via methods well known to those of ordinary skill in the art. The rubber portion 238 ultimately engages an inner wall 240 of the rail portion 212 of the support member 214 as the locking bolt 234 is tightened, whereby the rubber portion 238 prevents damage to the inner wall 240 of the rail portion 212 when the locking bolt 234 forcibly secures the channel member 230 to the rail portion 212. A relatively rigid offset member 242 fabricated from relatively rigid rubber is disposed between an outer wall 244 of the rail portion 212 and an inner wall 246 of the channel member 230, whereby, the offset member 242 prevents damage to the outer wall 244 of the rail portion 212 when the locking bolt 234 secures the channel member 230 to the rail portion 212. Further, the offset member 242 can be laterally sized to cooperate with the longitudinal dimension of the locking bolt 234, whereby, when a rail portion 212 is encountered having a lateral dimension that is proximate to the distance separating the inner walls 246 and 247 of the channel member 230, the lateral dimension of the offset member 242 can be decreased to a dimension that enables the rail portion 212 to insert into the channel member 230, thereby promoting the insertion of the offset member 242 between the outer wall 244 of the rail portion 212 and the inner wall 246 of the channel member 230.
The bracket member 210 of the countertop mold 200 may include a triangular configured bracket support member 248 (
The bracket support member 248 is secured to the bottom wall 250 of the horizontal member 224 of the bracket 210 via a fastening screw 254 that secures the horizontal form member 228 to the top wall 256 of the horizontal member 224 of the bracket member 210. The fastening screw 254 inserts through an aperture 258 in the support member 248, though an aligned aperture 260 in the horizontal member 224, and is forcibly rotated into the wooden horizontal form member 228. The wooden vertical form 226 member is secured to the inner wall 262 of the vertical member 222 of the bracket 210 via a fastener 266 inserted through an aperture 268 in the vertical member 222 and forcibly rotated, whereby, the fastener 266 ultimately inserts into the vertical member 222.
In operation, a reusable countertop mold 200 forms a countertop 202 having an integrally joined overhang portion 220. The mold 200 includes a predetermined quantity of reusable bracket members 210 dimensioned to secure first and second substantially vertical and horizontal form members 226 and 228 adjacent to a substrate 204 secured to a rail portion 212 of a cabinet member 214. The quantity and dimensions of the reusable bracket members 210 are determined via the peripheral dimensions of the substrate 212, the horizontal and vertical dimensions of the overhang portion 220, and the weight of the material ultimately disposed upon a form member 218 detachably secured to the bracket members 210. The preferred distance separating adjacent reusable brackets 210 is about three feet for a linear side of the substrate 204 perimeter 208, and about two feet for a curved or arcuate side of a substrate 204 perimeter 208 with at least one bracket member 210 secured to each side of the substrate 204 perimeter 208 irrespective of the length or quantity of the substrate 204 sides.
The dimensions of the reusable form member 218 are determined by the peripheral dimensions of the substrate 204, the horizontal and vertical dimensions of the overhang portion 220, and the weight of the material ultimately disposed upon the form member 218. As the dimensions of the overhang 220 increase and/or the weight of the overhang deformable material increases, the quantity and dimensions of the bracket members 210 increase; and the dimensions of the form member 218 increase. The quantity and dimensions of the bracket members 210, and the dimensions of form member 218 required for forming a selected countertop 202 and overhang portion 220 are well known to those of ordinary skill in the art. After installation of the reusable countertop mold 200, a preselected deformable material is disposed upon the substrate 204 and flows upon the form member 218 until a predetermined “thickness” for the deformable material is achieved; whereupon, the surface of the deformable material is configured to include a design pattern and/or leveled to a planar surface. After the deformable material has solidified, the mold 200 is removed and made available for new projects.

In the event that the longitudinal dimension of the inner edge 267 results in the insertion edge 267 engaging an existing fastener 271 when the inner horizontal portion 276 is inserted between the substrate 204 and rail portion 212, at least one and preferably two recesses 269 are included in an edge portion of the inner horizontal portion 276 to receive the existing fastener 271 and avoid engagement between the existing fastener 271 and the inner horizontal portion 276 when the inner horizontal portion 276 is forcibly slid between the substrate 204 and the rail portion 212. Two recesses 269 are provided, when only one is required to receive a fastener 271 that would obstruct insertion of the inner horizontal portion 276, to provide a user of the modified bracket 272 two placement positions for the inner portion 276 relative to the fastener 271 when inserting the inner portion 276 between the substrate 204 and the rail portion 212.
The recesses 269 avoid engagement between the horizontal portion 276 and the existing fasteners by visually aligning one of the two recesses 269 with an exposed top portion of an existing fastener, then urging the edge portion of the horizontal portion 276 between the substrate 204 and the rail portion 212 until the outer vertical wall 284 of the inner vertical portion 275 engages the outer wall 244 of the rail portions 212. The recesses 269 include a triangular configuration with the base portion of the triangle having a length relatively longer than the diameter of the existing fastener, thereby providing sufficient tolerance to avoid engagement between the inner edge 267 and the fastener 271 should the insertion direction of the horizontal portion 276 become skewed. Further, the recesses 269 guide the insertion of the inner horizontal portion 276 should either side wall of the recess 269 engage the fastener 271. The distance between the base of the triangular recess 269 and the peak of the recess portion 276 is sufficient to allow the insertion of the inner horizontal portion 276 until the outer vertical wall 284 of the inner vertical portion 275 engages the outer wall 244 of the rail portion 212.
The outer horizontal portion 274 includes at least one and preferably two apertures 277 for receiving screws (not depicted) that secure a horizontal form member 228 (see
In operation, a predetermined number of first modified brackets 272 are forcibly inserted between the substrate 206 and the rail portion 212 about the perimeter 208 of the substrate and vertical and horizontal form members 226 and 228 are detachable secured to the modified brackets 272, whereby, a continuous reusable countertop mold 200 with the modified brackets 272 continuously extends outside the perimeter 208 of the substrate 204 to receive a deformable material together with the substrate 204 that ultimately solidifies, thereby forming a countertop 202 having an integrally joined overhang portion 220, whereupon, the first modified bracket 272 is forcibly extracted from between the substrate 204 and the rail portion 212, and the form members 226 and 228 secured to the modified bracket 272 are forcibly separated from the countertop 202.

The second modified bracket 290 further includes a bracket support member 248, as depicted and secured in
The U-bolt 295 is secured to the support plate 294 via two securing nuts 297, whereby, the U-bolt 295 is disposed about the cabinet member 214 and through the support plate 294; whereupon, threaded end portions 298 of the U-bolt 295 rotational receive the securing nuts 297, resulting in the U-bolt and the support plate 294 tightly secured to the cabinet member 214 and enabling the second modified bracket 290 to support a deformable material disposed upon the vertical and horizontal form members 226 and 228. A myriad of alternatives to the “U” bolt 295 for securing the support plate 294 or similar configured plate to the cabinet member 214, include but not limited to “C” configured clamps, fasteners inserted in a non-visible side of the support member 214, and duct tape.
The foregoing description is for purpose of illustration only and is not intended to limit the scope of protection accorded this invention. The scope of protection is to be measured by the following claims, which should be interpreted as broadly as the inventive contribution permits.
