CLAMP FOR CLAMPING A PIPE OR CONDUIT TO A RIGID BARRIER

Abstract

A method of clamping a conduit comprising a cylindrical conduit (tube or pipe) to an aperture in a rigid barrier by steps of providing a clamp with a wide plate with a peripheral flange on an obverse end and a narrower boss back surface on an opposite end and with a central hole extending through the plate and the boss, and with a radial slot extending outwardly from a central hole to peripheral edges of both the plate and the boss. The clamp is installed onto a pipe or conduit by inserting a wedge into the radial slot; sliding the clamp onto the tube pipe until it is in contact with a rigid barrier; affixing the clamp to the rigid barrier with adhesive or fasteners; and removing the wedge from the radial slot.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a method for clamping a conduit to a barrier, with the conduit comprising a tube or a pipe and the barrier comprising a rigid support structure. This invention relates more particularly to clamps for rigidly securing a conduit to a barrier through which it passes; and methods of clamping the conduit to the barrier.

When a conduit in the form of a tube, a pipe for plumbing or an electrical conduit is inserted through a hole drilled or cut through a barrier, e.g. a rigid support structure, a wall, a bulkhead, etc., for attachment to a fixture, there is a problem. The problem is how to secure the conduit in a fixed position relative to the barrier so that it is prevented from sliding in and out through the hole or twist laterally, vertically or at an angle in response to a force exerted upon the fixture attached to the pipe or tube. For example in the case of a plumbing fixture such as a shower head or service valve which is attached to a pipe extending through a hole in a wall, it is important to affix the pipe in position to prevent the shower head from moving in and/or out through the hole in the wall or twisting at an angle after installation of the plumbing fixture is completed. In addition, in the case of a number of plumbing fixtures such as shower heads and the like, an escutcheon plate comprising a decorative plate is provided to surround the pipe on the exterior of the wall through which the pipe extends. For example escutcheon plates are provided behind a plumbing fixture such as a faucet in a bathtub or a shower. There is the additional problem in that case which is that the device which secures the conduit in position must be able to be hidden behind the thin escutcheon plate supplied with the plumbing fixture.

I have also found that it is necessary to clamp a conduit such as a pipe or tube which passes through a barrier (rigid support) such as a wall, bulkhead, floor, ceiling, cabinet, fence, etc. to hold fixtures in a fixed position.

I have also found that to maintain the desired esthetic appearance of a plumbing installation, it is often advantageous to employ a thin invisible escutcheon clamp in accordance with this invention which secures the pipe in a fixed position, but which can be hidden behind an escutcheon plate. The escutcheon plates provided by the manufacturer of the plumbing fixture are usually shallow. Thus, in order for a pipe clamp to be hidden from view, I have found that it is desirable to supply an invisible escutcheon clamp which is thin enough to fit behind such a shallow escutcheon plate. At the same time, such a shallow pipe clamp must provide a rigid clamping force that will prevent sliding of the pipe in and out of the barrier, wall or bulkhead. I have also sound that various types of clamps need to be provided with individual characteristics suitable for diverse applications.

Moreover there is a need for various routines (i.e. sequences of method steps) for installation of a clamp for affixing a conduit to a barrier.

In the case of new construction where a clamp is needed for installation of a conduit through a wall, one set of routine steps is required for cold installations of plastic or iron clamps.

In another case of new construction a modified routine is required for installation of a conduit through a wall, for cold installations of plastic or iron clamps for a utility fixture.

In still another case of new construction a modified routine is required for installation of a conduit through a floor or ceiling, for cold installations of plastic or iron clamps for a utility fixture.

In the case of a utility-copper hot installation for new construction a modified routine is required for installation of a conduit for hot installations of a stamped metal conduit clamp for a utility fixture.

In the case of a repair application where a clamp is needed for installation of a conduit through a finished wall, one set of routine steps is required for cold installations of plastic or iron clamps.

In another repair application a modified set of routine steps is required for installation of a conduit through a wall, for cold installations of plastic or iron clamps for a utility fixture.

In yet another repair application a modified routine steps is required for installation of a conduit through a floor or ceiling, for cold installations of plastic or iron clamps for a utility fixture.

In the case of a utility-copper hot installation for a repair application a modified routine is required for installation of a conduit for hot installations of a stamped metal conduit clamp for a utility fixture.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

Pipe Clamp for Barriers Such as Walls or Bulkheads

In accordance with this embodiment of the present invention a conduit clamp includes a clamp plate with a peripheral flange and boss on the reverse side with a radial slot in the clamp plate, the flange and the boss comprising a split in the clamp. The clamp is composed of a flexible material such as plastic or a metal stamping that will hold a tubular structure or a pipe by means of tension against the surface of the pipe or tube and the inside surface of the clamp plate boss. The flange is then glued or bolted to the wall or bulkhead that it is passing through to secure the pipe or tube in a permanent position.

Visible Tube Clamp (VTC)

FIGS. 1A and 1B show several different partially-sectioned views of a Visible Tube Clamp (VTC) 10 in accordance with this invention. FIG. 1A is a partially-sectioned, perspective view of the VTC 10 with the section taken along section line 1B-1B in FIG. 1A. The VTC 10 is shown with a boss 17 in the rear thereof inserted into a hole 23 through a barrier 22 which for example is a bulkhead or a wall. A flange 15 on the front of the VTC 10 has a back 19 next to the barrier 22. FIG. 1C shows the VTC 10 of FIG. 1B which is permanently installed in the hole 23 through the barrier 22 by adhesive 26 and screw 25 in FIG. 1C or by a bolt 25′. A conduit 24 is installed in a conduit hole 14 through the VTC 10. FIG. 1D is a modification of FIG. 1C with the boss 17 shown intact and with adhesive 26 and a screw 25′ assembled with a threaded nut 27 holding the VTC 10 in position.

In more detail, FIG. 1A is a partially-sectioned, perspective view of the VTC 10 which is a round, one piece unit for clamping a tube such as tube 24 shown in FIGS. 1C and 1D. The VTC 10 is shown inserted into the clamp hole 23 through a partially-sectioned barrier 22 which such as a wall or a bulkhead. In FIG. 1A the front of the VTC 10 comprises a flat, thin, wide cylindrical clamp plate 12. Behind the clamp plate 12 is a narrower, round boss 17. On the periphery of the clamp plate 12 is a clamp flange 15 with a greater radius than the boss 17. The clamp plate 12 and the boss 17 are hollow in that they have a conduit hole 14 extending from the front to the back of the VTC 10 along the central axis thereof. In other words, the clamp plate 12 is a round disk on the front of the VTC 10. The narrower, yet round boss 17 formed on the back of the VTC 10 is integral with the clamp plate 12. The clamp plate 12 includes the clamp flange (collar) 15 that is coplanar with the front surface of the clamp plate 12 and is formed on the margin thereof. In this embodiment, as shown in FIG. 1A, the clamp flange 15 is beveled on its periphery and the clamp flange 15 has a circular (round) periphery. In this embodiment the clamp boss 17, which is a hollow cylindrical tube, lies behind the clamp plate 12. The boss 17 has a central axis coaxial with the central axis of the clamp plate 12. The conduit hole 14 which is coaxial with the central axis of the clamp plate 12 and boss 17 of the VTC 10 extends from the front of the clamp plate 12 to the back of the boss 17. A radial slot 11 that is formed in one side of the VTC 10 extends from the inside of the conduit hole 14 to the exterior of the tube clamp plate 12 and it also extends to the exterior of the boss 17. The Visible Tube Clamp (VTC) 10 is composed of an elastic material which has a suitable modulus of elasticity for temporarily being deformed but which returns to its normal shape and providing a clamping force when the cause of the deformation force is removed. In accordance with the method of this invention, the clamp hole 23 has been bored or cut through a barrier 22 which comprises a rigid support structure. For purposes of explanation and illustration of features of the VTC 10, FIG. 1A shows clamp 10 (with no pipe inserted therein) inserted into the clamp hole 23 in the barrier 22.

An alternative to the conduit hole 14 being coaxial with the conduit clamp 10, the axis of the conduit hole 14 can be pitched at an angle such as 10, 20 or 30 degrees with respect to the conduit clamp 10 to provide for a conduit which is to slant at an angle such as a pipe to be connected to a shower head or a conduit which needs to connect at an alternative angle to a fixture.

FIG. 1B is a sectioned, side elevation of the VTC 10 taken along section line 1B-1B in FIG. 1A. Flange 15 extends radially from the margin of clamp plate 12 and is juxtaposed with the front wall of the barrier 22. The VTC 10 includes the boss 17 on its back. The radial slot 11 is seen in the clamp plate 12 and the flange 15 on the front of the VTC 10 and the radial slot 11 is seen in the boss 17. The conduit hole 14 extends through the center of the VTC 10 concentric with the clamp plate 12, the clamp flange 15 and the boss 17. The radial slot 11 extends out from the interior of the conduit hole 14 from the front to the back of the VTC 10. Two optional fastener holes 16 extend through the flange 15 from its front surface 18 to its back surface 19 with the holes 16 exposing the surface of the barrier 22 into which a threaded fastener 25 is shown inserted in FIGS. 1C and 1D. The VTC 10 with the radial slot 11 in the split (slotted) clamp plate 12 and with the split (slotted) raised boss 17 is preferably composed of a flexible material such as plastic or a metal stamping that will hold a conduit by means of tension against the surface of the conduit and the inside surfaces of the clamp plate 12 and the boss 17. The back surface 19 of the flange 15 is then glued and/or bolted to a wall or a bulkhead that it is passing through to secure a pipe or a tube in a permanent position as illustrated by pipe 24 in VTC 10 in FIGS. 1C and 1D as described below.

FIGS. 1C and 1D show a pipe 24 inserted into the VTC 10 of FIGS. 1A-1B secured to the rigid support structure 22 by a threaded fastener comprising a screw 25 plus adhesive 26 between the back surface 19 of the flange 15 and the front surface 22F of barrier 22. FIG. 2C is a sectioned elevation which is a modification of FIG. 2B showing a pipe 24 extending through both the bulkhead VTC 10 and the barrier 22 with the pipe 24 clamped into position by the VTC 10. The screw 25 is shown securing the VTC 10 to the barrier 22. The adhesive material 26 which bonds the VTC 10 to the barrier 22 fills the gap between the back 19 of the flange 15 and the confronting surface of the barrier 22. In FIG. 1D, which is a modification of FIG. 1C, the VTC 10 is shown without the sectioning of the clamp plate 12 and the boss 17, showing how the clamp plate 12 and the boss 17 surround the clamped pipe 24.

Visible Clamp (VC)

FIGS. 2A-2G show views of a Visible Clamp (VC) 20 in accordance with this invention for installation of a conduit through a barrier such as the barrier 22 in FIGS. 1A-1D. The VC 20 is composed of an elastic material with a suitable modulus of elasticity for temporarily being deformed by applying leverage to the radial slot 11, but which returns to its normal shape whereby it provides a clamping force when the leverage is removed ending the deformation. FIG. 2A is a perspective view of the VC 20 which comprises a flat, thin, wide, hollow disk shaped clamp plate 12 in front and a narrower, hollow cylindrical boss 17 in the back, which is integral with the clamp plate 12. As in FIGS. 1A-1D, the clamp plate 12 includes the coplanar round flange 15 on its margin. As shown in FIG. 2A, the boss 17 lies behind the clamp plate 12 and the boss 17 has a central axis coaxial with the central axis of the clamp plate 12. A conduit hole 14, which is coaxial with the central axis of the clamp plate 12 and boss 17 of the VC 20, extends completely through the VC 20 from front the front of the clamp plate 12 to the back of the cylindrical boss 17. The radial slot 11 is formed in the side of the VC 20 reaching out from the conduit hole 14 to the periphery of the clamp plate 12 including the clamp flange 15 and the boss 17. To prepare for insertion of a pipe or tube through the VC 20, a lever pries the radial slot 11 open by exerting strain force on the VC 20. The VC 20 opens to widen the diameter of the tube hole 14 temporarily but the stress force of the VC 20 is sufficient to clamp/affix a pipe or a cylindrical tube in place thereafter.

FIGS. 2B and 2C are partially sectioned, perspective views of the VC 20 of FIG. 2A. FIG. 2B is a sectioned view of FIG. 2A taken through the clamp plate 12 and the boss 17. FIG. 2C is a modification of FIG. 2B with a section taken along the central axis of the VC 20 extending through the center of the conduit hole 14. As shown in FIG. 2A, the boss 17 is cylindrical and coaxial with the wider, thin, cylindrical clamp plate 12. Since the boss 17 has a narrower radius than the clamp plate 12, there is a flat flange 15 on the margin of the clamp plate 12, which extends outwardly beyond the radius of the boss 17 away from the central axis of the clamp 20. The conduit hole 14 extends through the center of the VC 20 concentric with the clamp plate 12, the flange 15 and concentric with the boss 17. In addition, fastener holes 16 for bolts or screws extend through the flange 15 (from its front surface 18 to its back surface 19) for fastening the VC 20 to a hard surface such as a bulkhead, wall, or a floor, etc. as illustrated by FIGS. 1A-1D and as will be described below.

FIG. 2B is a section taken from front to back through a third of the VC 20 with the slot 11 remaining. FIG. 2C is a section taken from front to back through the center of the VC 20. FIG. 2D is a front view of the VC 20 and FIG. 2E is a back view thereof. FIG. 2F is an inverted side view of FIG. 2D. FIG. 2G is a section taken along section line 2G-2G in FIG. 2E.

FIGS. 2A, 2B, 2D-2F show the radial slot 11 extending outwardly from the conduit hole 14 (i.e. from the central axis of the VC 20) through both the clamp plate 12 and the boss 17 to provide access for a lever to wedge the VC 20 partially open temporarily to permit the insertion of a conduit therethrough. The radial slot 11 extends outwardly from the interior of the conduit hole 14. The VC 20 is composed of a material which is moderately stiff but flexible enough to be deformed temporarily to open the conduit hole 14 without damaging the VC 20. In other words, the VC 20 has a modulus of elasticity which permits temporarily increasing the ID of the conduit hole 14 by using a lever to partially open the radial slot 11 in the VC 20 from the front of the clamp plate 12 to the back of the boss 17. As referred to herein, a stiffer material has a higher elastic modulus than a less stiff material. A lever (not shown) exerts strain force to open the VC 20 when that lever is inserted into the radial slot 11. After the lever is removed, the VC 20 continues to have a stress force sufficient to clamp/affix a pipe or a cylindrical tube to a rigid support structure. In accordance with the method of this invention, the conduit hole 14 is required to have an Inner Diameter (ID) slightly less than the Outer Diameter (OD) of a conduit to be inserted therein with the VC 20 which has an ID slightly less the than the OD specification of a standard tube or pipe. When the lever is removed from the radial slot 11 the VC 20 rigidly grips the conduit inserted therein.

FIG. 2D shows a rotated plan view of the VC 20 of FIG. 2A with the radial slot 11 on the right extending out from the conduit hole 14 and four fastener holes 16 extending through the flange 15. FIG. 2E shows the obverse side of the VC of FIG. 2D with the back end 13 of the boss 17 surrounding the conduit hole 14 and the back 19 of the flange 15 surrounding the boss 17.

FIG. 2F shows an inverted, elevation of the VC 20 of FIG. 2D with the radial slot 11 on the right and on the edge of the flange 15. The back end 13 of the boss 17 and the back of the flange 15 are shown. FIG. 2G is a sectioned, inverted elevation taken along section line 2G-2G in FIG. 2E through the central axis of the VC 20.

Invisible Escutcheon Clamp (IEC)

The Invisible Escutcheon Clamp (IEC) is preferably a flexible plastic model of a conduit clamp in accordance with this invention with or without mounting holes on the flange and an adhesive previously present or currently applied to the reverse (boss (17)) side of the flange. A wedge or screwdriver is inserted into the split area to expand the center hole in order to enable the clamp to slide over the tube or pipe. Once the clamp is near the correct position, the reverse side of the clamp is pressed onto the barrier so that the glue which is exposed bonds the flange and the clamp to the barrier. Mounting screws may also be applied. After the pipe or tube is adjusted to the desired position, the wedge is removed. An escutcheon plate is then positioned over the clamp to conceal it, making it “invisible”.

FIGS. 3A-3F show an IEC 30 for a conduit in accordance with this invention. FIG. 3A is a side elevation of the IEC 30 with the clamp plate 12 which is disk shaped on top with a round flange 15 on the margin thereof. As in FIGS. 1A-1D, FIG. 3B shows the clamp plate 12 is the front end of IEC 30 with the boss 17 below the clamp plate 12. The back end 13 of the boss 17 is shown in FIG. 3D. The IEC 30 is a flexible plastic model s without mounting holes through the flange 15 and which has adhesive or glue (not shown) applied to the back side 19 of the flange 15. Mounting hole can be added to the IEC 30. As in FIGS. 1A-1D. and 2A-2G, a pipe or tube is to be installed into the IEC 30 by inserting a wedge or screwdriver (or the like) into the radial slot 11 (the split area) to expand the center hole 14 in order to enable the IEC 30 to slide over the pipe or tube. Once the IEC 30 is near the correct position, the adhesive or glue on the back 19 of the flange 15 is exposed and the IEC 30 is pressed firmly against a barrier as in FIGS. 1C and 1D. Alternatively, mounting screws may also be applied through holes through the flange 15. After the pipe or tube is adjusted to the desired position, the wedge or screwdriver is removed. A conventional escutcheon plate (not shown) is then positioned over the clamp to conceal it, making it “invisible”.

Hose Bib Clamp (HBC)

The Hose Bib Clamp (HBC) is a flexible, heat-resistant plastic or stamped metal structure with a larger flange than for the Visible Tube Clamp (VTC). The flange can be any shape or size and may have one or more mounting holes. The plastic version is used with pipes or tubes that have threads (in the case of black iron pipes for instance) or compression fittings (copper, stainless steel, or brass pipes) that are not subject to excessive heat. The stamped metal version is for pipes or tubes that may have fittings soldered or welded nearby.

FIGS. 4A-4H show views of a Hose Bib Clamp (HBC) 40 in accordance with this invention. FIG. 4A shows a view of the obverse side of the HBC 40 with the radial slot 11 at the bottom The HBC 40 is a heat-resistant flexible plastic or stamped metal version of a tube clamp with a front boss 47 and an HBC flange 45 which is shown to be relatively larger than the flanges described above. The HBC flange 45 can be any shape or size, and has a conduit hole 44 and may have one or more mounting holes 16 through its flange 45 as shown in several of the drawings. The HBC 40 is installed with fasteners or with adhesive. FIG. 4B shows a left elevation of the HBC 40 with the radial slot 11 rotated to the front surface. FIG. 4C is a perspective view of the obverse side of the HBC 40 with the front boss 47 shown clearly. FIG. 4D is a sectioned left elevation of the HBC 40 taken along line 4D-4D in FIG. 4A. FIG. 4E is a sectioned, perspective view of the obverse side of the HBC 40 taken along line 4E-4E in FIG. 4A. FIG. 4F is a sectioned, perspective view of the obverse side of the HBC 40 taken along line 4F-4F in FIG. 4A. FIGS. 4G and 4H are photographs of the obverse side of a model of an HBC 40. As stated above, the plastic version of the HBC flange 40 is adapted for use with pipes or tubes that have threads (in the case of black iron pipes for instance) or compression fittings (copper, stainless steel, or brass pipes) that are not subject to excessive heat. The stamped metal version of the HBC flange 45 is adapted for use with pipes or tubes that may have fittings soldered or welded nearby.

Matching Plastic SQuare (MPSQ) Tube Clamp

FIGS. 5A-5H show views of a Matching Plastic SQuare (MPSQ) tube clamp 50 in according to this invention. FIG. 5A is a perspective view of MPSQ tube clamp 50, that is preferably composed of the same type of plastic as the plastic conduit it is intended to support. The MPSQ tube clamp 50 has a flat, thin, wide and square, hollow clamp plate 52, in front and a hollow cylindrical boss 57 in the back, which is integral with the clamp plate 52 and narrower than the clamp plate 52. FIG. 5A shows the clamp plate 52 with a square flange 55 rounded corners for illustration, but the MPSQ clamp 50 can be of any size or shape. The rounded corners are juxtaposed with four fastener holes 16 that extend through of the flange 55. As in the previous embodiments of this invention, the tube clamp 50 includes the radial slot 11 and the central conduit hole 14, which are described above. FIG. 5B is a plan view of the obverse side of the tube clamp 50. FIG. 5C is a left elevation of FIG. 5B showing the radial slot 11 in front, indicating the location of back 13 of the boss 17 on the bottom and also indicating the back 19 of the clamp flange 55. FIG. 5D is a sectioned view of the obverse side of the clamp 50 taken along line 5D-5D in FIG. 5B showing half of the tube and pipe hole 14; and which shows the solid structure of the clamp 50. FIG. 5E is a sectioned view of the obverse side of the clamp 50 taken along line 5E-5E in FIG. 5B which also shows the solid structure of the clamp 50. FIG. 5F shows the reverse side of the view of the clamp 50 in FIG. 5B. FIGS. 5G and 5H are photographs views of the obverse side and the reverse side respectively of a model of the clamp 50. Plastic conduit clamp 50 has a large flange 55 with a thicker boss 57 for additional support made of the same type of plastic as the pipe or tube it is intended to support (such as PVC). The difference between this version and those above is that the center of the boss 57 is not undersized and the clamping force is achieved by a chemical bond generated by the appropriate glue or bonding agent applied between the inner boss surface and the outer surface of the pipe or tube which is bonded thereto and held in position when it is assembled in place. In this case, a wedge or screwdriver is not necessary to open the MPSQ clamp 50.

Pentagonal Conduit Tube (PCT) Clamp

FIG. 6 is a perspective view of a Pentagonal Conduit Tube (PCT) clamp 60 with a pentagonal clamp plate 62 on the obverse side which includes a pentagonal flange 65 with fastener holes 16 proximate to the five corners of flange 65 and a cylindrical boss 67 on the reverse side of the PCT clamp 60.

        cabinet, etc.) to form a barrier hole 23 for the tube 24 (pipe of installing tubes or
        pipes in pipe clamps. In other words, to install the Invisible Escutcheon Clamp
        20, first trim around the barrier hole 23 with a knife or saw enough to allow the
        boss on the back of the clamp to pass into the surface of the barrier 22 (e.g. a
        wall or bulkhead. Referring to steps B1-B3 below, at this time, if the clamp 10,
        20, etc. is equipped with mounting holes 16, a template may be used to mark
        hole locations on the barrier 22 and anchors may be inserted in their proper
        positions around the perimeter of the barrier hole 23.
STEP B1 Are fastener holes needed about the access hole? If YES go to step B2.
        If NO go to step C.

STEP D  Insert a wedge (screwdriver) into edge of clamp slot 11 to open clamp hole 14
        with clamp boss 17 facing barrier hole 23 as wedge expands hole 14 enough to
        allow clamp 10 to fit over the end of pipe 24, leaving the wedge in place for now.
STEP E1 Is adhesive required on back of the clamp flange? If YES go to step E2?
        If NO go to step F.
STEP E2 Expose adhesive on bonding side of clamp flange or apply adhesive to bonding
        side of clamp flange
STEP F  With clamp slot still wedged open, slide clamp along the tube or pipe. Line up
        any screw holes with any anchor holes. Slide clamp over end of the (line up the
        mounting holes) and push adhesive coated side of flange towards barrier until
        on flange contacts barrier surface.
STEP G  Push clamp flange until the adhesive seats on the barrier and then press the clamp
        to bond the clamp flange to the barrier.
STEP H  If required, insert and tighten screws or bolts.
STEP I  Position the tube including any desired angle in the case of a bent shower head
        only. Other applications will most likely be straight although it is conceivable
        that the clamp may be produced with the center hole at any angle up to 45 degrees
        and still maintain structural integrity) and remove the screwdriver or wedge.
STEP J  Remove lever or wedge clamping the conduit in place
STEP K  Slide any escutcheon ring over the tube end to conceal the clamp.
