Description

BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure

The present disclosure relates generally to siding and siding accessories. The present disclosure relates more particularly to siding end pugs.

2. Technical Background

Siding products can simulate traditional materials such as wooden clapboards, cedar shakes and the like. Traditional wood siding materials are generally installed in overlapped single tiers or courses. Each wood clapboard course typically includes a row of horizontally or vertically elongated planks (clapboards), butted end to end. Except at the extreme top and bottom, each row is overlapped at its top edge by a next higher course, and in turn laps over a next lower course, to the edges of the sided area.

In multiple siding styles, clearance is needed to accommodate thermal expansion and contraction. Siding materials such as vinyl and other polymers and resins often have a high coefficient of thermal expansion, and regularly cycle through a range of temperature conditions due to exterior installations and exposure to the elements. Thermal expansion is accommodated by providing clearance that permits the siding to expand at higher temperatures and to contract at lower temperatures.

Clearance is also needed so that the ends of panels that extend up to obstructions, or terminate at outside corners or the like, can be fitted under covering molding strips during installation. Siding accessories such as J-moldings, for example, are used to frame windows, doors, roof lines, etc., where the moldings form channels to receive and cover the extreme ends of the panels. The panels need clearance, along the direction of elongation of the course, so that the installer can fit each endmost panel into its course and then slide the panel endwise into the channel of the J-molding or similar trim. The channel or trim should be deep enough to cover the end of the adjacent panel when the panel and the course as a whole have retracted in cold weather. The fit of the panels, fasteners, and any joints along the course should be loose enough so the panels can slide as needed.

The clearance can create large gaps which may cause the siding to appear unfinished or substandard. Accordingly, there is a need for an improved siding accessory that provides a more aesthetically appealing overall look while still maintaining the required clearance for the siding panels.

DETAILED DESCRIPTION

The present inventors have noted disadvantages of conventional methods of installing siding panels and accessories. In one example, the required clearance between the siding panels and accessories may cause an unfinished look to the siding. The present inventors have noted that the use of an end plug may create a more aesthetically pleasing look to the finished siding while still allowing for the appropriate clearance to accommodate for expansion and contraction due to external temperature conditions.

Accordingly, one aspect of the disclosure is a siding panel end plug having a body, a first locking mechanism, and a second locking mechanism. The first locking mechanism is configured to interlock with a second locking mechanism on a second siding panel end plug, and the second locking mechanism is configured to interlock with a first locking mechanism on a third siding panel end plug. Additionally, the siding panel end plug can be manufactured by injection molding. The structure of the end plug as well as the material of which it is constructed allow for appropriate expansion and contraction of the siding panel when the end plug is installed between the siding panel and a piece of trim.

One embodiment of such a siding panel end plug is described with respect to FIGS. 1-1-8 below. FIGS. 1-6 show an example siding panel end plug 100 according to an embodiment of the disclosure. The end plug 100 may comprise a front face 102 and a rear face 104 opposite the front face. The front face 102 may include two outwardly extending sections 106, 108 separated by a groove 105. As shown in FIGS. 1-3, the outwardly extending sections 106, 108 may have a rounded or curved profile. It should be understood in certain embodiments as otherwise disclosed herein the outwardly extending sections may have differently shaped profiles.

The rear face 104 of the end plug 100 may also include two outwardly extending sections 110, 112 separated by a groove 111. In some embodiments, the rear face 104 may be substantially identical to the front face 102. In certain embodiments as otherwise disclosed herein, the rear face 104 may have a different structure than the front face 102. Again, as shown in FIGS. 1-3, the outwardly extending sections 110, 112 may have a rounded or curved profile, but it should be understood in certain embodiments as otherwise disclosed herein the outwardly extending sections may have differently shaped profiles.

The front and rear faces 102, 104 are connected by a side face 114, which follows the shape of the outwardly extending sections 106, 108, 110, 112 and grooves 105, 111 of the front and rear faces 102, 104. A hollow space 116 is present between the front and rear faces 102, 104 and the side face 114 is open on the other side, as shown in FIGS. 2 and 4, which allows for the end plug 100 to interlock side by side with another end plug, as shown in FIGS. 9 and 10, and which is described in more detail below. The hollow space 116 extends along the entire length of the end plug 100. It should be understood that in some embodiments, the hollow space 116 may be formed as two separate hollow spaces, one in the upper region between outwardly extending sections 106 and 110, and another in the lower region between outwardly extending sections 108 and 112. Other configurations are possible as well.

The end plug 100 also includes a first end 118, and a second end 120, the first end being opposite the second end. In some embodiments, the first end 118 may be placed at or near a top edge of a siding panel and the second end may be placed at or near a bottom edge of a siding panel.

In certain embodiments as otherwise disclosed herein, the end plug 100 may be formed with specific dimensions as described herein with reference to FIGS. 3 and 4. For example, in some embodiments, the overall height H of the end plug 100 may be in the range of about 6 in. to about 12 in. In some embodiments, the width W of the end plug, or the distance between the front face 102 and the rear face 104, may be in the range of about 0.5 in. to about 1 in, for instance. In some embodiments, the length L of the top edge 118 may be in the range of about 0.5 in. to about 1 in.

Referring again to FIG. 2, the end plug 100 also includes a first locking mechanism 122 located at or near the first end 118. The first locking mechanism 122 is configured to interlock with a second locking mechanism of a second adjacent end plug, as described below. The interlocking connection facilitates the locking of the end plug during installation. The interlocking feature may also prevent gaps or misalignments between end plugs.

As shown in FIG. 5, the first locking mechanism 122 may comprise two grooves 124, which may be generally U-shaped. In some embodiments, more or less grooves may be present. The grooves 124 interlock with corresponding projections on a second end plug to secure the two end plugs together. The U-shaped grooves 124 each have a protuberance 126 located on one side. The protuberance 126 acts as a stop to secure the corresponding projections in place.

Referring again to FIG. 2, the end plug 100 further includes a second locking mechanism 130 located at or near the second end 120, which is configured to interlock with a first locking mechanism of another adjacent, or third, end plug, as described below. The second locking mechanism 130 comprises two projections 132, which may be in the form of generally L-shaped hooks, as best seen in FIG. 6. In some embodiments, more or less projections may be present. As mentioned above, the projections 132 interlock with corresponding grooves on another end plug to secure the two end plugs together. The projections 132 each include a barb 134, which interact with the protuberance 126 of the first locking mechanism 122 to secure the end plug in place.

Although the first locking mechanism 122 is shown as a groove and the second locking mechanism 130 is shown as a projection, it should be understood that in alternate embodiments the first locking mechanism may comprise one or more projections and the second locking mechanism may comprise one or more corresponding grooves. Additionally, it should be understood that in certain embodiments as otherwise disclosed herein the first and second locking mechanisms may comprise any suitable locking mechanisms, such as an adhesive, tape, hoop and loop, snap-fit, or barbed features, mechanical fasteners, or molded-in fasteners such as snap-joints, for example.

In use, a first end plug 100 can be connected to a second end plug 200, as shown in FIGS. 7-8. Like parts are designated by like reference numbers (i.e., first locking mechanism 122 of first end plug 100 is similar to first locking mechanism 222 of second end plug 200). The L-shaped hooks 132 of the second locking mechanism 130 on the first end plug 100 are inserted into the grooves 224 of the first locking mechanism 220 of the second end plug 200. When fully interlocked, the protuberances 226 abut the barbs 134 to securely connect the first end plug 100 to the second end plug 200. Additionally, when interlocked, the front faces 102, 202, and the rear faces 104, 204 of the end plugs align, as shown in FIG. 8.

As shown in FIGS. 9-10, a siding panel 300 is mounted onto a surface (not shown). In most instances, the surface is a vertical surface such as a wall of a building. The siding panel 300 is placed adjacent a siding accessory, such as a piece of trim 400. In certain embodiments as otherwise disclosed herein, the trim may be a J-channel or corner post, for example. As mentioned above, a gap or clearance is needed between the siding panel and the trim during installation in order to accommodate expansion and contraction of the panel during a range of external temperature conditions. In certain instances, a user may wish to fill in the gap while still allowing for sufficient clearance. Thus, as shown in FIG. 9, one or more end plugs 100 may be inserted between the first edge 302 of the siding panel 300 and the piece of trim 400 to fill the gap between the two pieces and allow for a more aesthetically appealing look, while still allowing for sufficient clearance for expansion and contraction of the siding panel. The end plugs may be interlocked end to end to extend from a top edge 304 of the siding panel to a bottom edge 306 of the siding panel 300.

FIG. 10 shows a view of the interlocking of four end plugs. When two end plugs 100, 200 are brought together end to end, the first locking mechanism of one end plug interlocks with the second locking mechanism of another end plug which secures them together, as described above with respect to FIGS. 7-8. Additionally, when two end plugs 100, 150 are brought together side by side, the two outwardly extending projections 106, 108 of the front face 102 and the two outwardly extending projections 110, 112 of the rear face 104 interlock with the hollow space 116 of another siding panel end plug to connect the end plugs together. As many end plugs may be connected together as is desired to fill the gap between the siding panel 300 and the trim 400.

FIGS. 11-12 show an example accessory for use with the end plug 100. The accessory may be in the form of a stop 140, which is used to hold the end plug 100 in place when installed on a siding panel 300. As shown in FIG. 11, two stops 140, 142 may be positioned on the end plug 100. In one embodiment, a first stop 140 is placed on the outwardly extending section 106 and a second stop 142 is placed on the outwardly extending section 108. The end plug 100 may include first and second indentations 144, 146 for receiving the first and stops 140, 142, respectively. The stops 140, 142 hold the end plug 100 in place on a siding panel so the end plug does not move or fall out.

Notably, the end plugs of the present disclosure are injection molded, which provides a cost savings during production, as well as a light weight product. The injection molding process also allows for a higher speed and higher volume close tolerance production.

The siding panel end plugs and stops of the present disclosure may be constructed of any known siding material, such as PVC, polymer, polypropylene, acrylic, Acrylonitrile Styrene Acrylate (ASA), fiberglass, aluminum, steel, any other plastic, wood, or metal, or combinations thereof.

As the person of ordinary skill in the art will appreciate, the siding panels disclosed herein may be constructed of a single piece or layer of material, such as vinyl, allowing for inexpensive production. In certain embodiments as otherwise disclosed herein, the material may comprise any known siding material, such as PVC, polymer, polypropylene, acrylic, Acrylonitrile Styrene Acrylate (ASA), fiberglass, aluminum, steel, any other plastic, wood, or metal, or combinations thereof.
