INVENTOR ELMER G BIELA ATT PATENTED 6 2 SHEET 3 OF 3 INVENTOR ELMER (5.81ELA 2 M BY Qumran MOLDING JOINTS AND UNIVERSAL MOLDING MEMBERS THEREFOR This invention relates to molding joints for thin wallpaneling and to molding members therefor.
Prefinished thin wall plywood paneling is used extensively throughout commercial as well as residential structures. The plywood paneling makes an inexpensive wall covering which is attractive and rich looking. Occasionally, the wall heighth is greater than the heighth of the paneling and a second paneling member must be added to the first, leaving a butt joint therebetween. Molding must be added to cover the edges of the paneling for a professional appearance. For this purpose, elongated H-shaped molding members, formed of extruded polyvinyl-chloride, have been provided to fit between the panels with one side of the H-shape flush against the wall and other side covering the butt joint. These I-I-shaped molding members are installed as the paneling is installed.
Similarly, inside comers formed by the junction of paneling members require a molding cover. For this purpose, similar molding members, shaped to fit the inside comer have been provided.
Still further, molding members are required for the baseboard, the ceiling, the top of the panel below the ceiling as well as for panels forming outside comers. Six different shapes are required for a complete set of molding joints. Each of these shapes must be properly colored for the finish color of the paneling. Additionally, each of these shapes is adapted only for a given thickness paneling. Thus, if a supplier had to stock four different color moldings, to fit panel thicknesses of one-eighth inch, 4 millimeters, three-sixteenth inch and onefourth inch, which are the most common panel thicknesses, he
would be required to stock a total of 96 different pieces in order to properly supply moldings for each job.
l have now discovered a simple two-piece universal molding construction for paneling joints which is less expensive to manufacture, installed quickly and simply, and which decimates the stock required for a supplier.
By various aspects of this invention one or more of the following, or other, objects can be obtained.
It is an object of this invention to provide a new and improved molding joint construction for thin wall paneling which is universal in application in that the same molding members can be used for all common joint configurations.
It is a further object of this invention to provide an improved molding joint construction for thin wall paneling in which the cover portion of the molding joint is not installed until after all construction and room decorating is completed.
It is a still further object of this invention to provide a more watertight molding construction in which a space in the molding receives a thin bead of water resistant adhesive or caulking compound, which will seal the edges of tile molding in bathrooms and the like whereby seepage of water behind the tile panels is prevented.
It is yet another object of this invention to provide a joint construction between two abutting thin wall paneling members in which construction molding members overlie the facing edges of the wall paneling.
It is yet another object of this invention to provide a cap molding joint construction for an edge of a thin wall paneling member.
It is yet another object of this invention to provide a molding construction for paneling members forming an inside corner.
It is another object of this invention to provide a joint construction for paneling members forming an outside comer.
It is still a further object of this invention to provide a molding construction for a joint between a thin paneling member and a ceiling or a floor.
It is still a further object of this invention to provide a molding construction for thin wall paneling, the molding being adaptable to different thickness panelings as well as differen joint configurations.
Other aspects, objects, and the several advantages of this invention are apparent to one skilled in the art from a study of this disclosure, the drawings, and the appended claims.
According to the invention, there is provided a molding construction for use in covers of paneling joints of varying configurations. The molding construction is formed from two interengaging elongated shapes, one of which has a portion fitting behind the paneling, and the other of which fits over the edge or edges of the paneling and over the one shape.
The molding construction includes as one shape an elongated retainer of a rigid resilient material having a flat base portion to be placed flush with a wall surface. The base portion includes a pair of arms extending upwardly from the base forming a receiving area therebetween and gripping means on the inner facing edges of the upper portion of the arms. A wide attaching flange is left at one side of the retainer base.
The other shape in the molding construction comprises an elongated T-shaped molding cap integrally formed of a flexible and resilient synthetic material. The molding cap has first and second outwardly extending cover flanges and a depending tongue therebetween, with one of the outwardly extending cover flanges being of a width substantially greater than the other of the cover flanges. The tongue has a lower portion of a thickness to fit within the receiving area of the retainer and has means at a lower portion to engage the receiver gripping means so that the tongue lower portion is securely held by the arm when it is within the retainer receiving area.
The invention will now be described with reference to the accompanying drawings in which:

Referring now to the drawings, and to FIG. 1 in particular, there is shown a floor and a pair of walls 12 and 14 forming an outside comer. A lower paneling sheet 18 and an upper paneling sheet 20 are fixed to wall 12. A lower paneling sheet 22 and an upper paneling sheet 28 are fixed to the wall 14. A divider molding 26 is secured between the lower paneling sheet 18 and the upper paneling sheet 20, and between the lower paneling sheet 22 and the upper paneling sheet 24. An outside comer molding 28 fom1s a junction between the lower paneling sheets 18 and 22, and between the upper paneling sheets 20 and 24. A floor molding 30 forms a junction between the floor 16 and the lower paneling sheets 18 and 22.
Reference is now made to FIGS. 5 and 6 for a description of the components which make up each of the molding joints. A retainer 32 has a flat base portion 34 with upstanding arms 36 and 38 forming a receiving area therebetween. The arms extend inwardly at the upper portions thereof forming inwardly facing serrated edges 40. The upstanding arm 38 is positioned to one side of the transverse center of the flat base portion 34 leaving a wide flange portion 39. The upstanding arm 36 is positioned near an edge of the flat base portion 34 leaving a short edge flange 37.
The serrated edges 40 of each upstanding arm 36 and 38 are formed by sloping surfaces 42 and undercut surfaces 44 which are parallel to the base portion 34.
A molding cap 46 has a wide cover flange 48, a narrow cover flange 50 and a depending tongue 64 extending therebetween. The wide cover flange 48 and the narrow cover flange 50 are formed so that they curve downwardly toward the tongue 64. The wide flange 48 has a beaded end portion 52 of thickened material and three angularly disposed outer 50 at the end portion thereof. The bottom 60 is parallel to the short flange 50 at'the end thereof.
The tongue 64 has a serrated lower portion 66 formed by inwardly sloping surfaces 68 and return surfaces 70 which are perpendicular to the tongue.
The retainer 32 can be formed out of any suitable plastic material. Rigid resilient plastics such .as rigid polyvinylchloride, acrylics, and high density polyolefins are preferred. Since the base 32 is always hidden from view, it can be made in any color from inexpensive scrap material. The retainer is preferably made as an extrusion.
The molding cap 46 can be formed of any suitable plastic material which is rigid yet pliable and resilient enough to bend into the shapes illustrated in the drawings. The wide cover flange 48 must be of a length and flexibility so that the end portion'can be bent through an angle of at least 90 as shown in the drawings. A plasticized rigid polyvinylchloride is suitable for this purpose. Other vinyl polymers and olefin polymers are also suited for this molding cap 46. The molding cap 46 is preferably extruded.
Reference is now made to FIG. 2 which illustrates the use of the retainer 32 and cap molding 46 asa divider between two wood panel sheets. As seen in FIG. 3,.the wide flange 39 fits behind the paneling sheet 18 which is secured to the wall through any suitable fastening means. The retainer 32 can be installed behind the paneling sheet 18 as the paneling sheet is secured to the wall. The narrow flange 37 fits behind the paneling sheet 20 which is in turn secured to the wall. The paneling sheets 18 and 20 securely hold the retainer 18 in position. The cap molding 46 is secured to the retainer 32 through the tongue 64 whose serrated edges 66 engage the serrated edges 40 of the upstanding arms 36 and 38. The wide flange 48 is bent upwardly to extend in a direction parallel to the flat base portion 34 of retainer 32 such that the flat surface 56 of the bead portion 52 contacts the outer surface of the upper paneling sheet 20. The narrow flange 50 is also bent upwardly somewhat so that it is substantially parallel to the base portion 32 whereby the flat surface 60 of bead portion 58 is flush with the outer surface of the lower paneling sheet 18.
Reference is now made to FIG. 3 which illustrates the retainer and cap molding as used for an outside comer. The lower paneling sheet 22 is secured to the wall so that the side edge thereof extends outwardly a short distance of the corner. The retainer 32 is positioned with the outer edge of flange 37 in contact with the lower paneling sheet 22. In this position, the narrow flange'37 serves as a spacer for the retainer 32. A
nail 80 can be driven through the short flange 37 to secure the retainer to the wall. Altemately, or in addition thereto, a nail 81 can be used to secure flange 39 behind the lower paneling sheet 18. Themolding cap 46 is secured to the retainer 32 through the depending tongue 64 whose serrated surfaces 66 engage the serrated surfaces 40 of the retainer arms 36 and 38. The wide flange 48 of the cap molding 46 is bent slightly outwardly so that the bead portion 52 extends around the outer surface of the paneling sheet 22 with the flat surface 54 flush against the outer face. By this construction, visible gaps between the cap molding 46 and the outer surface of paneling sheet 22 are eliminated. The narrow flange 50 is positioned similarly to that illustrated in FIG. 2. The narrow flange 50 is bent outwardly slightly so that the flat surface 60 is flush against the outer surface of paneling sheet 18.
Reference is now made to FIG. 4 which illustrates the use of the cap molding and retainer as a floor molding. The retainer 32 is spaced upwardly slightly from the floor l6 and is secured behind the paneling sheet 18 by nails and/or 78 which extend through the narrow flange 37 and the wide flange 39 respectively. The cap molding 46 is secured to the retainer 32 through the tongue 64 whose serrated surfaces 66 engage the serrated surfaces 40 of arms 36 and 38. The wide flange is bent outwardly so that the flat surface 56 of bead portion 52 is flat with the floor 16. The narrow flange 50 of the cap molding 46 is bent so that the flat surface 60 of bead portion 58 is flush with the outer surface of paneling sheet 18.
Reference is now made to FIGS. 7 and 8 which show the use of the molding construction of the invention in an inside comer. In FIG. 7 there is illustrated an inside corner formed by paneling sheets 72 and 74 and having an inside corner molding joint 76 therebetween. In FIG. 8, the details of the molding joint are illustrated. The retainer 32, is secured in place by fitting the wide flange 39 beneath the paneling sheet '72. The edge of the narrow flange 37 is spaced from the paneling board 72. The edge of paneling sheet 74 is positioned snugly in the corner formed between the two walls. If desirable, a nail 78 can be used to hold the paneling sheet 72 and the retainer 32 in place. The cap molding 46 engages the retainer 32 through depending tongue 64 whose serrated surfaces 66 engage the serrated surfaces 40 of the retainer arms 36 and 38. The wide flange 48 is bent outwardly so that the flat surface 56 of bead 52 is flush with the outer surface of the paneling sheet 74. The narrow flange 50 is bent slightly back so that the flat surface 60 is flush with the outer surface of the paneling sheet 72. 1
Reference is now made to FIG. 9, 10 and l 1 which illustrate two additional uses of the molding construction in atub and shower enclosure environment. In such environments, water damage behind tile paneling is a serious problem. In FIG. 9
there is shown a tub 82 and tile walls 84 and 86 of, the type conventionally used in bathroom tubev enclosures. A cap molding construction 88 is provided between the tile 84 and the wall 92 to which it is attached. A tub molding is provided between the tube and the tile walls 84 and 86.
The details of the cap molding construction will now be described with reference to FIG. 10. The retainer 32 is secured in place on top of the tile 84 by positioning the long flange 39 behind the tile 84. The tile is secured to the wall by conventional adhesive means. The arm 38 rests against the top portion of the tile 84. A waterproof adhesive seal 94 is provided between the arm 38 and the tile 84. A second waterproof adhesive seal is provided between the upper portion of the retainer 32 and the wall 92. In this manner, the joint is completely watertight so that moisture cannot seep behind the tile 84.
The molding cap 46 is secured to the retainer 32 through tongue 36 whose serrated surfaces 66 engage the serrated surfaces 40 of the retainer arms 36 and 38. The wide flange 48 follows its normal contour so that the flat edge 55 of beaded portion 52 is flush with the outer surface of wall 92. The narrow flange 50 is bent outwardly slightly so that the flat edge 60 of the beaded end portion 58 is flush with the outer surface of the tile wall 84. v
The details of the tub molding 90 will now be described with reference to FIG. 11. In this molding construction, the retainer can be secured in place a spaced distance above the tub 82 through a nail 80. The bottom edge of the tile 84 then rests against retainer arm 38 with the wide flange-portion 39 behind the tile 84. Desirably, a waterproof adhesive seal 98 is provided between the top edge of tub 82 and retainer arm 36. Further, a waterproof adhesive seal 100 is provided between the bottom edge of tile 84 and retainer arm 38. In this manner, a completely water proof seal is provided between the tub 82 and the tile 84, thereby preventing moisture from seeping behind tile 84. The molding cap 46 is secured to retainer 32 through tongue 64 whose serrated surfaces 66 engage the serrated surfaces 40 of retainer arms 36 and 38. The wide flange 48 is bent outwardly such that the flat surface 56 of the beaded end portion 52 is flush with the top surface of the tub 82. The narrow flange 50 is bent outwardly slightly so that the flat surface 60 of beaded end portion 58 is flush with the outer surface of tile 84.
It will be appreciated from the foregoing that the invention provides a universal molding construction which is adapted to many different common joint configurations as well as to different thickness wall paneling. In addition, the molding construction is very well adapted for use in high moisture areas such as bathrooms wherein water insoluble adhesives are use advantageously to seal the paneling members from moisture.
It will be appreciated that the universal nature of this molding construction requires but few parts to be stocked. For example, the same retainer and molding cap can be used for different thickness paneling such as one-eighth inch, 4 millimeters, three-sixteenths inch and one-fourth inch, the most common paneling thicknesses. in addition, the same retainer can be used for all different color paneling since the retainer will always be hidden from view. Thus, the molding supplier need only stock the retainer and as many modling caps as is required for the different coloring panels. For example, if the supplier had four different color moldings, he would have to stock four different color molding caps and one retainer, a total of five parts. This stocking requirement is in distinction to the conventional practice which requires 96 different parts.
The total construction is quite inexpensive to manufacture. The retainer can be manufactured in any color and even scrap material can be used. The cost of the scrap material is far less than the pure color material. Thus, the cap molding can be made from the more expensive pure material and the retainer can be made from very inexpensive scrap material.
The invention permits the finished molding cap to be added to the joint at a time after the paneling has been installed and after all construction has been completed. Thus, the molding cap is less likely to be damaged or spattered with paint during the time of construction.
Whereas the invention has been described with reference to an engaging means comprising a tongue on the molding cap and arms on the retainer, it is apparent that an equivalent engaging means for most purposes, although not preferred, would comprise a reversal of these parts, i.e., a pair of arms on the cap molding and a tongue on the retainer.
Reasonable variation and modification are possible within the scope of the foregoing disclosure, the drawings, and the appended claims without departing from the spirit of the invention.
