A molded seat assembly comprises an insert having an upper and a lower surface, a peripheral edge, and a ridge disposed adjacent to the peripheral edge. A seat portion comprised of a plastic material is molded directly to the insert whereby the ridge is adapted to prevent the flow of the plastic material beyond the ridge. The plastic material contacts the ridge and melts or softens the ridge. The ridge is then deformed forming both a cohesive bond and a locking engagement between the seat portion and the insert.
Description
- The present invention generally relates to marine seat assemblies and, more specifically, to a roto-molded seat assembly having a molded-in mounting insert and method of making same. The method includes the step of molding a seat body over a portion of the insert.
- Traditionally, seating assemblies, such as marine seats, have been molded by a variety of techniques such as roto-molding and blow-molding. Roto-molded seats have been disfavored since metal fasteners are required to be held in place in the mold during the molding operation so that the molded assembly can later be aligned and attached to a fixture such as a seat support assembly. This technique added to the complexity of the molding operation. Additionally, prior art molded seats have had an undue amount of flexibility which imparted abnormal feel and discomfort to the person sitting in the seat. Metal and plywood inserts have been used in order to reduce the flexibility of the prior art seats but have met with unacceptable results.
- The prior art has been unable to produce a roto-molded seat assembly having a mounting insert integrally molded therein because the heat of the fluid plastic utilized for forming the seat body portion of the seating assembly, has caused deformation or warping of the mounting insert which creates alignment problems when attempting to use fasteners, such as screws, to attach the seat assembly to a base.
- The prior art has not successfully addressed the problems set forth above for roto-molded seat assemblies. Thus, there has been a need for an improved roto-molded seat assembly which provides increased strength, rigidity, and reduced manufacturing expense. There has also been a need for an improved roto-molding method of manufacturing seat assemblies which provides for an insert to be molded into the seat assembly without causing deformation of the insert and without the subsequent alignment problems set forth above.
- The improved seat assembly of the present invention provides a roto-molded seat assembly having increased rigidity and lower manufacturing costs than the prior art seat assemblies. The seat assembly includes an insert having an upper and lower surface, a peripheral edge, and a ridge disposed adjacent to the peripheral edge. A seat portion comprised of a plastic material is molded directly to the insert whereby the ridge prevents the flow of the plastic material beyond the ridge.
- In a method according to the present invention, a seat body is molded over an insert leaving a portion of the insert partially embedded in the molded seat body. A mold is provided having an inner surface and an orifice, wherein the inner surface of the mold defines an outer surface of the seat body. An insert is disposed in the mold orifice with the portion of the insert to be embedded into the seat body positioned in the mold. The insert includes at least one peripheral edge and at least one ridge disposed adjacent to the peripheral edge and in the preferred embodiment an aperture whose perimeter is defined by an edge and ridge. A fluid plastic material is introduced into the mold and forced against the inner surface of the mold, the peripheral edge of the insert, the ridge of the insert and in the preferred embodiment about the edge of the aperture. The fluid plastic material softens or partially melts the peripheral edge of the insert. The peripheral edge is partially deformed forming a locking engagement between the seat body and the insert. The plastic material comprising the seat body and the plastic material comprising the insert can also cohesively bond together providing a secure seal between the seat body and the insert. The ridge prevents the flow of the plastic material beyond the ridge thus preventing the fluid plastic material from deforming the insert. In the preferred embodiment, the edge of the aperture is also softened and partially melted to deform and form a locking engagement between the seat body and insert.
- In a preferred embodiment, a roto-molding process is used to mold the seat assembly.
- Other advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
- FIG. 1 is a perspective view of a seat assembly in accordance with the present invention;
- FIG. 2 is a cross-sectional view of the insert and seat body assembly taken along line2-2 of FIG. 1; and
- FIG. 3 is a cross-sectional view of the insert in accordance with the present invention.
- Referring to FIG. 1, a seat assembly according to the present invention is generally shown at10. The
seat assembly 10 includes aseat body 12 which includes awall 13 defining aseat back portion 14 and aseat bottom portion 16 having anunderside 18. Theseat body 12 is constructed of a plastic material, such as a thermoplastic, of the type known in the art, which is preferably made by a roto-molding process or other known processes. The plastic material which comprises theseat body 12 is preferably a high density linear polyethylene material having a general thickness of approximately 4-8 millimeters. - The
seat assembly 10 also includes a mounting insert orplate 20 which is disposed on theunderside 18 of theseat bottom portion 16. Themounting insert 20 is a prefabricated plastic piece constructed of, for example, an injection molded plastic material such as high-density polyethylene. For reasons set forth below, theseat body 12 and the mounting insert 20 preferably are made from the same plastic material. Typically, themounting insert 20 will have a general thickness of approximately 4 to 8 millimeters. - The
mounting insert 20 includes aflat attachment platform 22, abase portion 24 havingends 26 andsides 28. Themounting insert 20 also includes anupper surface 32 and alower surface 34. Themounting insert 20 can have at least one portion embedded in theseat body 12 as described below. - Referring specifically to FIG. 2, the
mounting insert 20 has a coextensiveperipheral edge 36. Theperipheral edge 36 has a substantially tapered cross-section. Theperipheral edge 36 of themounting insert 20 is partially embedded in thewall 13 of theseat body 12. That is, upon molding of theseat body 12, the fluid plastic material comprising theseat body 12 engulfs a portion of theperipheral edge 36. The plastic material which comprises thewall 13 of theseat body 12 substantially engulfs abottom surface 37 of theperipheral edge 36 and substantially covers atop surface 39 of theperipheral edge 36 of themounting insert 20. However, the plastic material comprising the seat body is not substantially disposed over any other portion of themounting insert 20. - A
ridge 38 disposed adjacent to theperipheral edge 36, extends upwardly from anupper surface 32 of theinsert 20 and is adapted to prevent the flow of plastic material beyond the ridge. That is, theridge 38 prevents the plastic material from being deposited on theupper surface 32 of theinsert 20. Theridge 38 continuously extends about theinsert 20. - Both the
peripheral edge 36 and theridge 38 of theinsert 20 can also become partially cohesive with theouter surface 13 of theseat body 12. That is, if compatible plastic materials are utilized for both theinsert 20 and theseat body 12, the materials comprising the respective parts can form a cohesive bond there between. Additionally, theperipheral edge 36 and theridge 38 of theinsert 20 can both be partially deformed by the hot plastic material forming theseat body 12 and can thus provide locking engagement between theinsert 20 and theseat body 12. The deformedperipheral edge 36 and thedeformed ridge 38 allow for a mechanical lock to be formed between the deformedperipheral edge 36 and thedeformed ridge 38 having the plastic material forming theseat body 12 disposed there over. - Referring to FIGS. 2 and 3 in the preferred embodiment, the
insert 20 includes at least oneaperture 40 disposed therein. As is shown in the Figures, theaperture 40 preferably includes aninternal edge 42 having atop surface 44. Theinternal edge 42 extends substantially continuously about theaperture 40. The aperture can also include an upwardly extendingridge 46 which continuously extends about theaperture 40. - As discussed above, the
internal edge 42 has a substantially tapered cross-section. Theinternal edge 42 and theridge 46 are partially embedded in thewall 13 of theseat body 12. Upon molding of theseat body 12, the plastic material forming theseat body 12 engulfs a portion of theinternal edge 42 and theridge 46. The plastic material which forms thewall 13 substantially engulfs thetop surface 44 of theinternal edge 42 and also contacts theridge 46. - The
internal edge 42 of theinsert 20 can also become partially cohesive with thewall 13 of theseat body 12. That is, as described above, the materials comprising the respective parts can form a cohesive bond there between. - Additionally, both the
internal edge 42 and theridge 46 can be partially deformed by the hot plastic material forming theseat body 12 and can thus provide locking engagement between theinsert 20 and theseat body 12. The deformedinternal edge 42 and thedeformed ridge 46 allow for a mechanical lock to be formed between the deformedinternal edge 42 and thedeformed ridge 46 having the material comprising theseat body 12 disposed there over. - In the method of making the molded
seat assembly 10 in accordance with the present invention, theinsert 20 is disposed into a mold. The mold can have an insulative material, such as TEFLON, applied between the mold and the insert to prevent the transmission of excessive heat from the mold to the insert which could deform theinsert 20. Theinsert 20 is disposed in an orifice of the mold having an inner surface which defines the outer surface of the seat body. A hot fluid plastic material which in roto-molding is generated by disposing solid, powdered plastic material in the mold cavity and heating the mold and rotating the mold, is simultaneously disposed over both the inner surface of the mold, theperipheral edge 36 andinner edge 42 of theinsert 20. This step can be performed, for example, by any plastic molding method which is well known in the art. The preferred plastic molding method is roto-molding. The hot fluid plastic material contacts theperipheral edge 36 andinner edge 42 of theinsert 20 and can begin to soften or even melt at least a portion of theperipheral edge 36 andedge 42. Theridges upper surface 32 of theinsert 20, which if this occurred could distort theinsert 20. - When an
aperture 40 is present in theinsert 20, a portion of the orifice of the mold or a separate tool can be disposed in the regions of theinsert 20 located between theridges upper surface 32 of theinsert 20. In other words, a portion of the orifice of the mold or a separate tool forms a dam which prevents the flow of fluid plastic material onto theupper surface 32 by physically blocking the flow at theridges - After the formed
seat assembly 10 is removed from the mold, while it is still somewhat malleable, theinsert 20 is placed over a mandrel or form and is loaded or stressed in order to remove any bends or deformation in theinsert 20 caused by heat and then theseat assembly 10 is placed in a cooling bath. - The fluid plastic material cools and hardens forming the
seat body 12. As the fluid plastic material cools, limited shrinkage of the plastic material can occur, drawing together theperipheral edge 36 and theseat body 12. Theperipheral edge 36 and theridge 38, theedge 42, and theridge 46 can be deformed, thereby producing locking engagement with theseat body 12. Additionally, as discussed above, cohesive bonding between theperipheral edge 36, theridge 38, the edge 4, and theridge 46 and the fluid plastic material forming theseat body 12 can also occur. - The
resultant seat assembly 10 has increased rigidity and is lighter in weight than prior art seat assemblies. - A preferred description of this invention has been disclosed; however, one of ordinary skill in the art would recognize that certain modifications would come within the scope of this invention. For that reason, the following claims should be studied in order to determine the true scope and content of this invention.
