Sillcock for robust re-installation

Abstract

The present invention pertains to problems associated with the installation of new sillcocks in existing masonry or other building materials. A sillcock, or hose bib having broader base plate is provided to prevent collapse especially in older or damaged building materials and to minimize damage to new installations.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 The typical hose bib of the prior art is shown.

(2) FIG. 2 The present invention, drawn substantially to scale

(3) FIG. 3 A preferred embodiment of the invention as shown in FIG. 2

(4) FIG. 4 An embodiment of the invention as shown in FIG. 2, adapted for specific purposes such as prior wall damage in identifiable areas.

DETAILED DESCRIPTION

(5) The typical hose bib of the prior art is shown in FIG. 1. A relatively large hole must be made in the mounting wall, intended to receive the pipe or conduit (typically metal) which conducts water from a supply source, usually within the building structure to the faucet 105, the faucet generally being an integral part of the sillcock. The structure may be commercial or residential in nature and the sillcock is typically installed through an outer wall, though variations can exist.

(6) Installation may be a complex matter and, as will become more apparent below, is typically performed by an experienced professional craftsman such as a plumber.

(7) As the usual case is for installation to involve the outer wall of a structure, damage to the wall presents a serious problem. Outer walls provide not only privacy and barriers to wind, heat, (and/or cold) noise and so on, but often may have security implications as well. Furthermore outer walls provide structural support, which may at times become critical, such as during storms, sub-zero weather and the like.

(8) Typical location of a sillcock may well be determined by factors unrelated to the foregoing structural and practical considerations. Thus installation might exacerbate these problems, for example requiring boring and/or drilling into mounting material which cannot be guaranteed to be accomplished without structural implications, making a repeat or imperfect job more than a mild inconvenience.

(9) The present invention in particular corrects the problematic confluence of a hole intended for the passage of the water pipe with holes needed to provide anchoring and aligning with screw- or bolt-holes 102. As shown in FIG. 1, the prior art typically minimizes the sillcock's requirement for material by providing anchor holes 102 close to the faucet 105.

(10) As shown in FIG. 2, the sillcock 200 of the present invention present invention, as a fundamental improvement, expressly provides an extended base-plate 201, thus allowing a much larger separation between the various holes in the sillcock, which improvement correspondingly allows a much larger separation between the various holes to be made (or used, in the case of existing holes) in the mounting wall, whether masonry, wood, concrete or other material. The diameter of the base plate 201 is approximately 3.5 inches.

(11) In the case of a sillcock reinstalled where one has previously been, the present invention almost completely eliminates the usual problems that may arise by progressive weakening of mounting material. Especially in cases where multiple installations, which may have required repeated boring to accommodate sillcocks manufactured by different entities and thus not being expected to align their respective hole needs, the present invention far surpasses the prior art in minimizing possible further compromising of the mounting structure.

(12) As further shown in FIG. 3, in a preferred embodiment of the present invention, the long dimension 303 remains approximately 3.5 inches as in the former case, but the height 304 is reduced to about 2 inches, giving the base plate 301 a rounded, oval or extended diamond-like shape. This shape allows for a less intrusive form and, depending on the choice of plate thickness, less use of metal.

(13) Other embodiments of the present invention focus on variations which further seek to provide for a less risky and trouble free installation. Embodiments provide, among other benefits, for choices in hole location which may be more advantageous for specific installation jobs such as, for example, a sillcock 400 with bolt anchor holes 402 having an angular offset 404 with respect to a diameter 403 drawn through the main pipe-hole as shown in FIG. 4. Note that the diameter shown 403 pertains to a round plate, though in some offset embodiments the base plate does not extend to its maximum diameter at angles apart from the actual anchoring locations of the bolts. Such an embodiment is particularly useful in its ability to mount onto least-damaged material, in the case where a pre-existing sillcock, with holes as shown in any of the prior figures, incurred damage to the mounting surface. The angular offset may be in either direction.

(14) As a surprising result, the larger surface area of the plate 201, 301, 401, as compared with the prior art, permits, in an embodiment for a somewhat thinner material to be used without risk of failing to provide adequate material for secure anchoring of the bolts in holes 202, 302, 402. The thinner material allows for a degree of enhanced flexibility of the plate, which allows for improved ability to conform to the surface of the mounting material (typically masonry). An attendant benefit is that a secure fit will not be prevented even if the mounting wall surface happens to be uneven. Washers (not shown) may be employed if necessary, in ways well known in the art, to ensure that any excessive torque applied to the bolts does not risk damaging the plate.

(15) As a further surprising result, the aforementioned reduced thickness, in an embodiment, of the plate, permits easier re-drilling of new anchor holes for bolts without the need for specialized tools. Re-drilling might be beneficial in cases where a first choice for hole placement is precluded by prior damage to the mounting wall.

(16) As yet another surprising result of the present invention, the increased separation between the pipe hole and the anchor holes allows for the use of an expanded range of washers or spacers, both in materials and size, These washers or spacers may be chosen in such a way as to exert an increased compressive force over a larger surface area, a feature which may especially be of value in the case of mounting material which is weak or has been made weak by repeated installations, even when masonry holes made to match elements 202, 302, 402 have collapsed together into the pipe hole.

(17) Those experienced in the field of this invention should, based on the detailed descriptions of the objectives and new methods, be able to understand the logical possible variations. They will be able to adopt appropriate materials, dimensions and geometries depending on the various applications and needs of different installations, not specifically shown in this application, but within the general goals and objectives of this invention. Specifically, the word bolt is understood to include other types of fasteners known in the art, which may or may not be threaded, such as screws, rivets or the like. The word pipe is used to designate a fluid conduit which is typically, though not exclusively, liquid, especially water, but may be considered for purposes of this invention to include other substances, including gases.
