Description

FIELD OF THE INVENTION

This invention relates in general to system and devices for attaching siding.

BACKGROUND OF THE INVENTION

The use of continuous insulation is mandated for some climates in the United States by newer energy codes, such as 2012 International Energy Conservation Code (IECC) and 2012 International Green Construction Code. The purpose of continuous insulation is to eliminate thermal breaks that reduce thermal efficiency of insulation placed between framing members such as wall studs.

Siding can be placed over rigid insulation boards or foam that are placed outside of an air barrier (AB)/weather-resistive barrier (WRB). The use of continuous insulation with siding requires the siding to be connected to the to the support or back-up wall behind the AB/WRB. Some ties that pass through the continuous insulation and result in thermal leaks that reduce the efficiency of the continuous insulation.

The present inventor recognized the need for a siding attachment system that reduces thermal bridging where the continuous insulation is transversed. The present inventor recognized the need for a siding attachment system that is less susceptible to deterioration by moisture and weather conditions.

When installing continuous insulation panels, the panels are often installed in complete contact with the AB/WRB on the back-up surface. This prevents proper drainage of water on the exterior face of the AB/WRB. Water can be trapped in the minute gap between the continuous insulation and AB/WRB due to capillary action. This trapped water can cause accelerated deterioration of ties and other components.

The present inventor recognized the need for a siding attachment system that creates a gap between the continuous insulation panels and AB/WRB. This gap facilitates drainage.

Continuous insulation panels are often installed with adhesive backing to ensure they stay in place. This adhesive backing can impede drainage of water on the drainage plane and can degrade and fail over time under certain circumstances. This adhesive backing will also results in additional labor and material costs.

The present inventor recognized the need for a siding attachment system that can retain the continuous insulation panels in place and eliminate the need to rely on adhesive backing.

The present inventor recognized the need to transfer some compressive force from the siding attachment system onto the insulation to reduce or eliminate the possibility of buckling under compressive loads and to reduce the effective span within the cavity.

DETAILED DESCRIPTION

The following description is presented to enable any person skilled in the art to make and use the invention. For the purposes of explanation, specific nomenclature is set forth to provide a plural understanding of the present invention. While this invention is susceptible of embodiment in many different forms, there are shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.

FIGS. 1-5 show a siding attachment system 50. The system 50 comprises a base 52 and an attachment member 54. In some embodiments, both components are manufactured using a semi-rigid plastic material. FIG. 3 shows the system deployed in one type of application. The base is attached to a backup wall 38. In some embodiments, the backup wall 38 may have an air barrier (AB) and/or weather-resistant barrier (WRB) 34, placed over an exterior wall board or sheathing 36, placed over wall studs 38a. In some applications, the base may be attached over the air barrier and/or weather-resistant barrier 34. The base may be used on other walls or backup wall arrangements known in the art.

The base 52 has a back plate 56 and an engaging wall 58 extending from the back plate. In some embodiments, the wall 58 extends perpendicular from the back plate. The wall 58 has a plurality of base teeth 60 extending along opposite sides of the engaging wall 58, a back end 62 adjacent the back plate 56, a front end 64 opposite the back end 62. The base teeth on a first side of the engaging wall are mirror image identical to the corresponding base teeth on the opposite side of the engaging wall as shown in FIG. 2.

While the engaging wall is shown having teeth along its entire length between the back end 62 and front end 64, in some embodiments, a portion thereof may be flat or blank without teeth. The engaging wall has upper and lower guide bars 66, 68 on opposite sides of the engaging wall that extend beyond the teeth. The guide bars have a flat surface.

The back plate 56 comprises through going mounting fastener apertures/holes 70. While three apertures are shown any number of apertures can be provided and placed about the back plate. Fasteners, such as screws 71, are used to secure the base plate 56 to the backup wall 38.

The attachment member 54 has a mounting plate 72 and a receiving wall 74. The receiving wall 74 has opposite outer wall portions 76, 78, and a receiving recess or gap 80 between the outer wall portions 76, 78. An end opening 88 provides access to the receiving recess 80 opposite the mounting plate 72. At an outer end of each wall portions 76, 78 opposite the base is a toothed section 82. The tooth section 82 comprises receiving teeth 84 extending from the wall portions 76, 78 into the receiving recess 80. The receiving teeth 84 on the first outer wall portion 76 are mirror image identical to the corresponding receiving teeth on the opposite second outer wall portion 78, as shown in FIG. 2. Therefore there are matched pairs of opposite receiving teeth that engage corresponding opposite sides of the engaging wall, as is shown in FIG. 2.

A blank portion 86 extends from the tooth section 82 to the mounting plate 72.

The receiving wall has upper and lower guide recesses 90, 92 in each of the outer wall portions 76, 78. The guide recesses provide side directed access to and out of the receiving recess 80. The upper and lower guide recesses 90, 92 are configured to receive the guide bars 66, 68 respectively. When the guide bars are received in the guide recesses, the attachment member 54 is secured against vertical movement in the directions H and I relative to the base. The recess 90, 92 are perpendicular to the mounting plate 72, and more specifically to the front face 95.

In one application, the base 52 is attached to the backup wall 38 with screws 71, insulation panels 32 are placed over a portion of the base 52 adjacent one or both sides of the engaging wall 58. The thickness of the back plate 56 of the base 52 spaces the insulation panels 32 from the backup wall 38. The resulting gap 57 facilitates drainage. Then the receiving wall 74 of the attachment member 54 is moved so that end opening 88 is aligned with the engaging wall 58 of the base 52, and more particularly the front end 64 of the engaging wall 58. The front end 64 is arrow shaped. The opposite sides of the end opening have angled surfaces to receive the arrow shaped front end 64. The attachment member 54 is moved in the direction A of FIG. 2. The receiving teeth 84 engage and slide over the base teeth 60 and drive the outer wall portions 76, 78 outward and away from each other in the directions C and D, respectively. The outer wall portions are driven outward because the widest portion of the wall long the tooth section is wider than the narrowest portion of the receiving recess 80 in the tooth section.

As the attachment member 54 moves in the direction A, the outer wall portions 76, 78 reciprocate or ratchet between expanding in the directions C and D, respectively, as the widest portion of the base teeth 60 encounter the widest portion of the receiving teeth 84, and then falling back in the directions E and F, respectively, as the narrowest portion of the base teeth 60 encounter the narrowest portion of the receiving teeth 84 as the recess teeth ride up and down along the base teeth. The outer wall portions are semi-flexible within a range of motion and biased in the directions E and F to a certain point at least sufficient to achieve the interlocked engagement of the receiving recess teeth with the base teeth as shown in FIG. 2.

The attachment member 54 can be moved forward in the direction A until a rear face 94 of the mounting plate 72 contacts or is in close proximity to a front face 42 of an insulation panel 32. In this way, the mounting plate secures and holds the insulation panel(s) 32 adjacent the backup wall 38 without the need for adhesive backing on the insulation panel(s). The attachment member has a range of motion from where only the first base tooth 60a of the engagement wall in is the recess adjacent the first recess tooth 84a to where the arrow shaped end front end 64 is received in the corresponding arrow shaped end portion 98 of the recess 80. Therefore, the attachment member is movable relative to the base to account for and secure insulation panels of various depths.

The attachment system 50 transfers compressive force or load that is provided to the exterior of the siding, such as by winds, through the attachment system, onto the backup wall 38. In some applications, the force or load is transferred from the attachment to the outer face of the insulation panel, through the insulation panels and onto the backup wall 38. In some applications, the mounting plate is substantially parallel to the back plate when the attachment member is joined to the base.

To remove the attachment member 54 from the base, the outer wall portions 76, 78 must be expanded in the directions C and D, respectively, until the receiving teeth 84 release from base teeth 60 sufficiently to allow clearance between the two sets of teeth and the attachment member to be withdrawn in the direction B of FIG. 2.

The front face 95 of the mounting plate 72 has a plurality of vertically extending fastener grooves 96. In some embodiments, these fastener grooves extend the entire length of the front face 95. The fastener grooves 96 receive the end point 48 of a fastener such as a nail 46. The groove prevents the nail, screw, or other fastener from moving out of place when first being driven or penetrating the front face 95. As shown in FIG. 3, a siding mount 44 of the siding system 30 is attached the mounting plate 72 by the nail 46. The mount 44 is shown spaced apart from the front face 95, but in some applications the mount will be in surface-to-surface contact with the front face 95.

From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred.
