This disclosure relates generally to a pipe clamp for supporting different sized conduits (including tubing and pipes) and for attaching the conduits to a mounting structure.
Plumbing pipes are supported to mounting structures using generally two types of pipe clamps: Half clamps and full clamps. Half clamps include a general “L”-shaped body which surrounds only a portion of the tube in order to secure it. Full clamps surround most (if not all) of the diameter of the tube body. There are generally two types of full clamps: Open loop “C” style and closed loop. Open loop “C” style clamps include a “C”-shaped body with two arms extending from a back portion. The back portion includes a nail receiving channel. A nail is inserted through the channel and driven into the mounting structure to secure the clamp to the mounting structure. A conduit is supported between the two arms.
Closed loop clamps include arms that completely encompass and wrap around the pipe. The ends of the arms abut against each other forming the nail receiving channel. A nail is inserted through the channel securing the two ends of the arms together, and driven into the mounting structure to secure the clamp to the mounting structure.
The foregoing background discussion is intended solely to aid the reader. It is not intended to limit the innovations described herein. Thus, the foregoing discussion should not be taken to indicate that any particular element of a prior system is unsuitable for use with the innovations described herein, nor is it intended to indicate that any element is essential in implementing the innovations described herein.
There are times when it is necessary to remove a pipe clamp after it has been installed onto a mounting structure. For example, the pipe clamp may be removed to remove the pipe, relocate the pipe, reposition the pipe clamp, or for other reasons. Conventional pipe clamps are often difficult to remove. Generally, the pipe clamps are secured to the mounting surface using a ring-shanked type nail. Once the head of the nail is fully inserted into the nail receiving channel, it is difficult to remove since the head of the nail is driven against a surface of the pipe clamp. The pipe clamps are removed by forcing a claw of a hammer, a prybar, certain pliers, or other prying tool between the mounting structure and an area of the clamp that is in direct contact with the mounting structure. The area on the pipe clamp where the nail exits the mounting structure is the preferred region of where to pry. Removing the pipe clamp from the mounting structure commonly results in claw marks and/or marring from the hammer, and can result in damage to the body of the pipe clamp. Another method for removing the pipe clamp includes grabbing the body of the clamp with pliers to pull it out, which may also result in damage to the body of the pipe clamp.
Full clamps are fastened to a mounting structure by inserting a nail thru both insertion holes at each end of the clamp. In closed loop full pipe clamps, this requires the clamp to be pressed and held together to maintain alignment of the nail insertion holes. Closed loop full clamps make it difficult to drive nails through the nail insertion holes because the clamp may only be released after the nail is driven through the nail insertion holes, which holds each end of the clamp together.
Therefore, there is a need for a pipe clamp capable of being removed from a mounting structure without causing damage to either the mounting structure or the pipe clamp, and maintaining adequate alignment of the nail receiving channels prior to inserting the nail during installation. The foregoing needs are met, to a great extent, by the pipe clamp disclosed in the present application.
An aspect of the present disclosure provides a pipe clamp that comprises a mounting post, an arm, and a hinge positioned between the mounting post and the arm. The mounting post has a first post end and a second post end spaced apart from the first post end. The mounting post defines a first arcuate recess that extends at least partially between the first post end and the second post end. The second post end includes a first coupling element. The arm has a first arm end and a second arm end spaced apart from the first arm end. The arm defines a second arcuate recess that extends at least partially between the first post end and the second post end.

The hinge is connected to the first post end of the mounting post and to the first arm end of the arm. The mounting post is rotatable relative to the arm about the hinge from an open position to a closed position. In the closed position the first coupling element is coupled to the second coupling element.
Another aspect of the present disclosure provides a pipe clamp that comprises a first arm, a second arm, and a hinge positioned between the first arm and the second arm. The first arm has a mounting end and an insertion end spaced apart from the mounting end. The first arm defines a first arcuate recess that extends at least partially between the mounting end and the insertion end. The first arm includes a first extension element.

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description section. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not constrained to limitations that solve any or all disadvantages noted in any part of this disclosure.
The foregoing summary, as well as the following detailed description of illustrative embodiments of the present application, will be better understood when read in conjunction with the appended drawings. For the purposes of illustrating the present application, there are shown in the drawings illustrative embodiments of the disclosure. It should be understood, however, that the application is not limited to the precise arrangements and instrumentalities shown. In the drawings:
Pipe clamps for supporting a pipe from a mounting surface are disclosed. A first pipe clamp (e.g. closed loop full pipe clamp) includes a mounting post, an arm, and a hinge positioned between the mounting post and the arm. The mounting post and the arm both include a coupling element configured to couple the mounting post to the arm. The mounting post is rotatable relative to the arm about the hinge from an open position to a closed position. In the closed position, the coupling elements of the mounting post and the arm are coupled together. The mounting post and the arm define a pipe recess within for supporting the pipe.
A second pipe clamp (e.g. open loop “C”-style pipe clamp) includes a first arm, a second arm, and a hinge positioned between the first arm and the second arm. Each of the first and second arms define an arcuate recess and include an extension element that extend from each arm toward the opposing arm. The extension elements and the hinge define a flex recess. The size and shape of the flex recess allow the first and second arms to rotate relative to one another about the hinge to receive the pipe within the arcuate recesses.
Certain terminology used in this description is for convenience only and is not limiting. The words “top”, “bottom”, “above”, “below”, “axial”, “transverse”, “circumferential,” and “radial” designate directions in the drawings to which reference is made. The term “substantially” is intended to mean considerable in extent or largely but not necessarily wholly that which is specified. All ranges disclosed herein are inclusive of the recited endpoint and independently combinable (for example, the range of “from 2 grams to 10 grams” is inclusive of the endpoints, 2 grams and 10 grams, and all the intermediate values). The terminology includes the above-listed words, derivatives thereof and words of similar import.
The pipe clamp 100 includes a mounting post 102, an arm 104, and a hinge 106 (e.g. a flex hinge) positioned between the mounting post 102 and the arm 104. The mounting post 102 has a first post end 108 and a second post end 110 spaced apart from the first post end 108. The mounting post 102 defines an arcuate recess 112, and further defines a first channel 114. The arcuate recess 112 is defined by an inner surface of the mounting post 102 and extends at least partially from the first post end 108 to the second post end 110. The inner surface of the mounting post 102 may include one or more axially extending ribs 116 spaced circumferentially about the inner surface. The ribs 116 extend from a front end 118 of the clamp 100 to a back end 120 of the clamp 100.
The mounting post 102 includes a first coupling element 122 positioned at the second post end 110. The coupling element 122 may include a protrusion 123 (e.g. latch) that extends from the second post end 110. An inner surface of the coupling element 122 may form a portion of the arcuate recess 112.
The arm 104 has a first arm end 124 and a second arm end 126 spaced apart from the first arm end 124. The arm 104 defines an arcuate recess 128, and further defines a second channel 130 that extends through the second arm end 126. The arcuate recess 128 is defined by an inner surface 129 of the arm 104 and extends at least partially from the first arm end 124 to the second arm end 126. The inner surface 129 of the arm 104 may include one or more axially extending ribs 132 spaced circumferentially about the inner surface 129 and extending from the front end 118 to the back end 120 of the clamp 100.
The arm 104 includes a second coupling element 134 positioned at or adjacent to the second arm end 126. The second coupling element 134 may include a notch 135 that is recessed within the arm 104. The notch 135 is configured to receive the latch 123 of the mounting post 102 within to removably secure the second arm end 126 of the arm 104 to the second post end 110 of the mounting post 102 (e.g. notch-latch coupling system).
The hinge 106 is connected to the first post end 108 of the mounting post 102 and the first arm end 124 of the arm 104. The mounting post 102 is rotatable relative to the arm 104 about the hinge 106 from an open position to a closed position. In the closed position, the latch 123 of the mounting post 102 is secured within the notch 135 of the arm 104, removably securing the mounting post 102 to the arm 104.
The mounting post 102 has an outer surface 144 that extends along at least a portion of the insertion end 138 of the pipe clamp 100. The outer surface 144 defines an opening 146 to the mounting channel 142. The mounting post 102 includes a relief protrusion 148A,B that extends from the outer surface 144 in a direction opposite the insertion direction A. The relief protrusion 148A,B is positioned in close proximity to the opening 146. In an aspect, the relief protrusion 148A,B is substantially adjacent to the opening 146. The relief protrusion 148A,B enables a prying tool to access a head of the fastener positioned within the mounting channel 142 to facilitate removal of the fastener from the pipe clamp 100.
The hinge 106 is positioned at the insertion end 138 of the pipe clamp 100. The outer surface 144 extends along the insertion end 138 of the pipe clamp 100 from the opening 146 of the mounting channel 142 to the hinge 106. The outer surface 144 may be curved such that the outer surface 144 at the opening 146 is spaced from the outer surface 144 at the hinge 106 along the insertion direction A. The curvature of the outer surface 144 forms a prying support (e.g. hammer support) for supporting the prying tool during removal of the fastener positioned within the mounting channel 142.
The arm 104 includes an extension element 150 that extends from the first arm end 124. With reference to
The arcuate recess 128 defined by the arm extends in a substantially circumferential direction about a center C of the pipe clamp 100. The arcuate recess 112 defined by the mounting post 102 also extends about the center C in the substantially circumferential direction when the mounting post 102 is in the closed position. The arcuate recess 152 of the extension element 150 extends in a substantially circumferential direction about an off-center OC location, which is off-set from the center C of the pipe clamp 100. Each of the arcuate recesses 112, 128, and 152 comprise a pipe recess configured to receive a pipe within the clamp 100. The center C is positioned on a pipe support axis that extends through the pipe clamp 100 from the front end 118 to the back end 120. The pipe support axis is substantially perpendicular to the insertion direction A and is positioned to align with a pipe axis of a pipe received within the pipe recess.
The mounting post 102 and the arm 104 may be integrally formed with the hinge 106 such that the mounting post 102, the arm 104, and the hinge 106 form a single unitary member. The hinge 106 may comprise a flexible hinge. Alternatively, the mounting post 102 and the arm 104 may be separate components manufactured independently of one another and coupled together by the hinge 106. In this alternative, the hinge 106 may comprise, for example, a type of pivot hinge.
After the pipe 160 is inserted into the pipe recess, the arcuate recess 128 of the arm 104 and the arcuate recess 152 of the extension element 150 extend about an outer surface of the pipe 160 at an arc angle of greater than 180°. In an aspect, the arcuate recess 128 of the arm 104 extends about the center C of the pipe clamp 100 at an arc angle of approximately 180°. When the pipe 160 is received within the pipe recess and the mounting arm 102 is in the open position, the inner surface of the arm 104 and the inner surface of the extension element 152 provide a force to the outer surface of the pipe 160 to hold the pipe 160 within the pipe recess. When the mounting arm 102 is transitioned to the closed position, the force applied to the outer surface of the pipe 160 by the arm 104 and the extension element 150 is increased.
After the pipe 160 is inserted into the pipe recess, the mounting post 102 is transitioned to the closed position by rotating the mounting post 102 relative to the arm 104 about the hinge 106. In the closed position, the latch 123 is positioned within the notch 135, securing the second post end 110 of the mounting post 102 to the second arm end 126 of the arm 104. The connection between the latch 123 and the notch 135 aligns the channel 114 defined by the mounting post 102 and the channel 130 defined by the arm 104, forming the linear mounting channel 142. The mounting post 102 may be transitioned to the closed position by applying a force F (see
When the pipe 160 is secured within the pipe recess, an outer surface of the pipe 160 contacts the ribs 116 and 132 of the mounting post 102 and the arm 104, respectively. The outer surface of the pipe 160 also contacts a distal end of the extension element 150. The ribs 116 and 132 and the distal end of the extension element 150 provide diametrical support to the pipe 160. The arcuate recesses 112, 128, and 152 of the mounting post 102, the arm 104, and the extension element 150 provide clearance for thermal expansion of the pipe 160.
After the pipe 160 is secured within the pipe recess with the mounting post 102 in the closed position, the pipe clamp 100 is mounted to the mounting surface 170. The pipe clamp 100 may be aligned with the mounting surface 170 such that a mounting surface 154 of the arm 104 lies flush against the mounting surface 170 at a location where the pipe 160 is to be supported. A fastener 172 is inserted into the opening 146, through the mounting channel 142, and through the mounting surface 170, thereby securing the pipe clamp 100 to the mounting surface 170.
The pipe clamp 200 includes a first arm 202, a second arm 204, and a hinge 206 (e.g. a flex hinge) positioned between the first arm 202 and the second arm 204. The first arm 202 has a first mounting end 208 and a first insertion end 210. The first arm 202 defines an arcuate recess 212, and further defines a channel 214. The arcuate recess 212 is defined by an inner surface of the first arm 202 and extends at least partially from the first mounting end 208 to the first insertion end 210. The inner surface of the first arm 202 may include one or more axially extending ribs 216 spaced circumferentially about the inner surface. The ribs 216 extend from a front end 218 of the clamp 200 to a back end 220 of the clamp 200.
The first arm 202 includes a first extension element 222 that extends from the first arm 202 in a direction towards the second arm 204. The first extension element 222 is positioned radially inward from the hinge 206. An inner surface of the first extension element 222 defines a portion of a tangential contact with a pipe when the pipe is positioned within a pipe recess of the clamp 200.
The second arm 204 has a second mounting end 224 and a second insertion end 226. The second arm 204 defines an arcuate recess 228, and further defines a channel 230. The arcuate recess 228 is defined by an inner surface of the second arm 204 and extends at least partially from the second mounting end 224 to the second insertion end 226. The inner surface of the second arm 204 may include the one or more axially extending ribs 216 spaced circumferentially about the inner surface. The second arm 204 includes a second extension element 232 that extends from the second arm 204 in a direction towards the first arm 202. The second extension element 232 is positioned radially inward from the hinge 206. An inner surface of the second extension element 232 defines a portion of the arcuate recess 228.
The hinge 206 is connected to the first mounting end 208 of the first arm 202 and the mounting end 224 of the second arm 204. The first arm 202 is rotatable relative to the second arm 204 about the hinge 206. Rotation of the first arm 202 relative to the second arm 204 in one direction causes the first insertion end 210 of the first arm 202 to move away from the second insertion end 226 of the second arm 202, and rotation of the first arm 202 relative to the second arm 204 in an opposing direction causes the first insertion end 210 of the first arm 202 to move toward from the second insertion end 226 of the second arm 202.
The pipe clamp 200 has an insertion end 238 and a mounting end 240 spaced apart from the insertion end 238 in an insertion direction A′. The pipe clamp 200 defines a mounting channel 242 that extends through the pipe clamp 200 in the insertion direction A′ from the insertion end 238 to the mounting end 240. The mounting channel 242 comprises the channel 214 defined by the first arm 202, the channel 230 defined by the second arm 204, and the flex recess 241. The mounting channel 242 is configured to receive a fastener (e.g. nail, screw, bolt or other similar type of fastener) therethrough from the insertion end 238 to the mounting end 240.
The first arm 202 has an outer surface 244 that extends along at least a portion of the insertion end 238 of the pipe clamp 200. The outer surface 244 defines an opening 246 to the mounting channel 242. The first arm 202 includes a relief protrusion 248A,B that extends from the outer surface 244 in a direction opposite the insertion direction A′. The relief protrusion 248A,B may be configured substantially similarly to the relief protrusion 148A,B of the pipe clamp 100 described above.
The outer surface 244 extends along the insertion end 238 of the pipe clamp 200 from the opening 246 of the mounting channel 242 to the first insertion end 210 of the first arm 202. The outer surface 244 may be curved such that the outer surface 244 at the opening 246 is spaced from the outer surface 244 at a location toward the first insertion end 210 along the insertion direction A′. The curvature of the outer surface 244 forms a prying support (e.g. hammer support) for supporting the prying tool during removal of the fastener positioned within the mounting channel 242.
The arcuate recess 212 defined by the first arm 202 and the arcuate recess 228 defined by the second arm 204 extend in a substantially circumferential direction about a center C′ of the pipe clamp 200. Each of the arcuate recesses 212 and 228 comprise a pipe recess configured to receive a pipe within the clamp 200. The center C′ is positioned on a pipe support axis that extends through the pipe clamp 200 from the front end 218 to the back end 220. The pipe support axis is substantially perpendicular to the insertion direction A′ and is positioned to align with a pipe axis of a pipe received within the pipe recess.
In an aspect, the arcuate recess 212 of the first arm 202 and the arcuate recess 228 of the second arm 204 extend about the center C′ of the pipe clamp 100 at a substantially similar arc angle. In an aspect, the arcuate recess 212 of the first arm 202 and the arcuate recess 228 of the second arm 204 form mirror images of each other when viewed from the front (see
The first arm 202 and the second arm 204 may be integrally formed with the hinge 206 such that the first arm 202, the second arm 204, and the hinge 206 form a single unitary member. The hinge 206 may comprise a flexible hinge that is configured to apply a force to each of the arms 202 and 204 when a pipe is inserted into the pipe recess.
The first insertion end 210 of the first arm 202 and the second insertion end 226 of the second arm 204 define a first lead-in surface 250 and a second lead-in surface 252, respectively. Each of the first and second lead-in surfaces 250 and 252 extend at first and second angles 256 and 258, respectively, relative to an axis X that extends through an opening 254 defined between the first and second insertion ends 210 and 226 of the first and second arms 202 and 204. In an aspect, the first angle 256 of the first lead-in surface 250 extends at an angle that is greater than 45° and less than 180°. In an aspect, the first angle 256 extends an angle of approximately 50°. In an aspect, the second angle 258 of the second lead-in surface 252 extends at an angle that is greater than 45° and less than 180°. In an aspect, the second angle 258 extends an angle of approximately 50°. In an aspect, the combined angle (e.g. the angle between the first lead-in surface 250 and the second lead-in surface 252) is at least 100°. Both the first and second angles 256 and 258 may extend at approximately the same angle. The first and second lead-in surfaces 250 and 252 may extend linearly outward from the opening 254.
After the pipe 260 is inserted, the pipe 260 is held within the pipe recess by the inner surface of the first arm 202 and the inner surface of the second arm 204. When the pipe 260 is secured within the pipe recess, an outer surface of the pipe 260 contacts the ribs 216 of the first and second arms 202 and 204. The outer surface of the pipe 160 also contacts distal ends of each of the first and second extension elements 222 and 232. The ribs 216, the distal ends of the first and second extension elements 222 and 232, and distal ends 223 and 225 of the first and second arms 202 and 204 provide diametrical support to the pipe 260.
After the pipe 260 is secured within the pipe recess, the pipe clamp 200 is mounted to the mounting surface 270. The pipe clamp 200 may be aligned with the mounting surface 270 such that a mounting surface 259 of the second arm 204 lies flush against the mounting surface 270 at a location where the pipe 260 is to be supported. A fastener 272 is inserted into the opening 246, through the mounting channel 242, and through the mounting surface 270, thereby securing the pipe clamp 200 to the mounting surface 270.
The mounting post 302 includes an extension element 350 that extends from a first post end 308. With reference to
An arcuate recess 312 defined by the mounting post 302 extends in a substantially circumferential direction about a center C″ of the pipe clamp 300. The arcuate recess 352 of the extension element 350 extends in a substantially circumferential direction about an off-center OC″ location, which is off-set from the center C″ of the pipe clamp 300.
After a pipe is inserted into the pipe recess, the arcuate recess 312 of the mounting post 302 and the arcuate recess 352 of the extension element 350 extend about an outer surface of the pipe at an arc angle of greater than 180°, and the off-center location OC″ may be transitioned to substantially align with the center C″ of the pipe recess. In an aspect, the arcuate recess 312 of the mounting post 302 extends about the center C″ of the pipe clamp 300 at an arc angle of approximately 180°.
The mounting post 402 may be transitioned to the closed position by applying a force F′ to the mounting post 402 in a post direction C′. The post direction C′ is substantially parallel to a post channel 414 that defined by the mounting post 402. The force F′ may be applied to an outer surface 444 of the mounting post 402 near an opening 446 of the post channel 414.
During mounting of the pipe clamp 500, the pipe clamp 500 may be aligned with a mounting surface of a mounting structure such that a mounting surface 554 of the arm 504 lies flush against the mounting surface of the mounting structure. The mounting surface 554 may define a relief recess 555 that is recessed from the mounting surface 554 such that the relief recess 555 is spaced apart from the mounting surface of the mounting structure when the pipe clamp 500 is mounted to the mounting structure. In an aspect, the pipe clamp 500 may be removed from the mounting structure by positioning an end of a prying tool within the relief recess 555 and prying the clamp 500 away from the mounting structure.
