This disclosure relates to fittings. More specifically, this disclosure relates to a fitting assembly that is adjustable in length.
Piping systems, such as fire sprinkler system piping and HVAC piping, can be mounted in a structure (e.g., a building) by a piping support assembly (e.g., hangers, stanchions, slides, guides, seismic braces, rollers, etc.). Some piping systems are subject to dynamic loads (e.g., seismic loads from an earthquake). Piping support assemblies can employ a sway brace to allow for movement of the piping system along with the structure in response to dynamic loads.
Further, pipes and piping systems can be supported by piping support assemblies at varying distances from the structure. Piping support assemblies (e.g., a seismic brace assembly) are typically of a fixed length, making it difficult to accommodate for varying distances between piping systems and the structure they are mounted to. For example, if the distance between the piping system and the supporting structure varies, a fixed-length piping support assembly may not be compatible with the entire piping system.

Various implementations described in the present disclosure may include additional systems, methods, features, and advantages, which may not necessarily be expressly disclosed herein but will be apparent to one of ordinary skill in the art upon examination of the following detailed description and accompanying drawings. It is intended that all such systems, methods, features, and advantages be included within the present disclosure and protected by the accompanying claims.
The features and components of the following figures are illustrated to emphasize the general principles of the present disclosure. Corresponding features and components throughout the figures may be designated by matching reference characters for the sake of consistency and clarity.
The present disclosure can be understood more readily by reference to the following detailed description, examples, drawings, and claims, and the previous and following description. However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that this disclosure is not limited to the specific devices, systems, and/or methods disclosed unless otherwise specified, and, as such, can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.
The following description is provided as an enabling teaching of the present devices, systems, and/or methods in its best, currently known aspect. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects of the present devices, systems, and/or methods described herein, while still obtaining the beneficial results of the present disclosure. It will also be apparent that some of the desired benefits of the present disclosure can be obtained by selecting some of the features of the present disclosure without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the present disclosure are possible and can even be desirable in certain circumstances and are a part of the present disclosure. Thus, the following description is provided as illustrative of the principles of the present disclosure and not in limitation thereof.
As used throughout, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an element” can include two or more such elements unless the context indicates otherwise.
Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.
For purposes of the current disclosure, a material property or dimension measuring about X or substantially X on a particular measurement scale measures within a range between X plus an industry-standard upper tolerance for the specified measurement and X minus an industry-standard lower tolerance for the specified measurement. Because tolerances can vary between different materials, processes and between different models, the tolerance for a particular measurement of a particular component can fall within a range of tolerances.
As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.
The word “or” as used herein means any one member of a particular list and also includes any combination of members of that list. Further, one should note that conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain aspects include, while other aspects do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more particular aspects or that one or more particular aspects necessarily include logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular aspect.
Disclosed are components that can be used to perform the disclosed methods and systems. These and other components are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these components are disclosed that while specific reference of each various individual and collective combinations and permutation of these may not be explicitly disclosed, each is specifically contemplated and described herein, for all methods and systems. This applies to all aspects of this application including, but not limited to, steps in disclosed methods. Thus, if there are a variety of additional steps that can be performed it is understood that each of these additional steps can be performed with any specific aspect or combination of aspects of the disclosed methods.
Disclosed in the present application is a fitting assembly and associated methods, systems, devices, and various apparatus. Example aspects of the fitting assembly can comprise a fitting and a fastener that can be selectively adjustable relative to the fitting. It would be understood by one of skill in the art that the disclosed fitting assembly is described in but a few exemplary aspects among many. No particular terminology or description should be considered limiting on the disclosure or the scope of any claims issuing therefrom.
As shown, the fitting assembly 180 can be configured for use with a pipe support assembly 100 in some aspects. The pipe support assembly 100 can comprise the pipe clamp 102, the brace member 104, and the mounting bracket 106, and can be configured for mounting a pipe 108 or piping system to a structure (e.g., a building). In example aspects, the brace member 104 can extend between the pipe clamp 102 and the mounting bracket 106, and the distance between the pipe clamp 102 and the mounting bracket 106 can be selectively adjustable. Moreover, example aspects of the brace member 104 can be configured for rotational motion with respect to the pipe clamp 102 and/or the mounting bracket 106.
The pipe support assembly 100 can comprise a pair of the fitting assemblies 180. The fitting assemblies 180 can attach the pipe clamp 102 and the mounting bracket 106 to the brace member 104. Example aspects of the brace member 104 can be formed as a hollow cylindrical tube defining a first end portion 104a, an opposing second end portion 104c, and an intermediate portion 104b extending therebetween. For example, the brace member 104 can be a one-inch Schedule 40 steel pipe, or another type and size of pipe that is known in the art. The ends of the hollow brace member 104 can be open to allow access to the interior of the brace member 104, as depicted. In some aspects, the brace member 104 can define end walls (not shown) or other closures for closing the open ends. Brace member 104 can be formed from any material or combination of materials that are known in the art, including but not limited to metal, plastic, resin, synthetic materials, and fibers.
As shown in
As shown, the C-shaped halves 110 are secured together such that the first ends 110a of the C-shaped halves 110 face one another and the second ends 110b of the C-shaped halves 110 face one another. In example aspects, as shown in
Inner surfaces of the C-shaped halves 110 and/or outer surface of the pipe 108 can comprise features for improving the grip between the pipe clamp 102 and the pipe 108 for a more secure engagement between the pipe clamp 102 and the pipe 108. For example, C-shaped halves 110 can comprise a gasket and/or teeth 170 configured to grip the pipe 108 received within the clamp channel 112. The improved grip aids in preventing the pipe 108 from moving with respect to the pipe clamp 102.
According the example aspects, the profile of the clamp channel 112 can be defined by the inner surfaces of C-shaped halves 110 and can be formed to substantially match the profile of the pipe 108. For example, as depicted, the pipe 108 can define a substantially circular cross-sectional shape and the clamp channel 112 formed by the C-shaped halves 110 can also define a substantially circular cross-sectional shape. However, according to other aspects, the channel 112 of the pipe clamp 102 can be formed with any desired cross-sectional shape, including, for example, oval, square, rectangular, triangular, trapezoidal, pentagonal, etc., to match varying cross-sectional shapes of piping. Moreover, the clamp channel 112 can be sized to accept the pipe 108 therein, and the size of the clamp channel 112 can be adjusted to substantially match, or be just slightly larger than, the size of the outer periphery of the pipe 108. This adjustment can be achieved by the appropriate tightening of the threaded nuts 118 on the threaded tail end 114b of the bolts 114, such that the clearance between the outer surface of the pipe 108 and the inner surfaces of the C-shaped halves 110 can be minimal.
A fastener bore 132 can be formed in the end wall 124a of the fitting 124. In the current aspect, the fastener bore 132 is a though hole, extending from an outer surface of the end wall 124a to an interior surface of the end wall 124a. The fastener bore 132 can be threaded to match the threading on the tail end 120b of the adjustable fastener 120, allowing the fastener 120 to be threaded with the fastener bore 132, and attaching the fastener 120 to the fitting 124. In example aspects, a centerline axis Cfb of the fastener bore 132 can be substantially aligned with the centerline axis Cba of the brace member 104, and as such, a centerline axis Cfd of the fastener 120 can be substantially aligned with the centerline axis Cba of the brace member. In such an aspect, the fastener 120 and the brace member 104 are oriented concentrically with respect to one another.
As shown in
Referring back to
As described above, the fastener 120 can define a threaded tail end 120b that can engage the threaded fastener bore 132 on fitting 124. Referring to
In a first example, it can be desired that the pipe 108 be supported eleven inches from a concrete ceiling (not shown), and the length of the pipe support assembly 100 can be twelve inches. To reduce the length of the pipe support assembly 100 so that the pipe support assembly 100 can support the pipe 108 eleven inches from the ceiling, the fastener 120 can be selectively threaded one inch deeper into the fastener bore 132 of the fitting 124, reducing the length of the pipe support assembly 100 from twelve inches to eleven inches. In a second example, it can be desired that the pipe 108 be supported thirteen inches from a concrete ceiling (not shown), and the length of the pipe support assembly 100 can be twelve inches. To increase the length of the pipe support assembly 100 so the pipe support assembly 100 can support the pipe 108 thirteen inches from the ceiling, the fastener 120 can be selectively un-threaded from the fastener bore 132 of the fitting 124 by one inch, elongating the pipe support assembly 100 to thirteen inches. It should be note that, in various aspects, the assembly of the fitting 124 and fastener 120 can comprise additional or other fasteners for attaching the fastener 120 to the fitting 124, provided that the fasteners allow for selective adjustment of the length of the pipe support assembly 100.
The protruding portion 142 of the mounting bracket 106 can comprise opposing first and second side walls 144. Note, in
Interior surfaces of the two opposing side walls 144 of the mounting bracket 106 can be separated by a gap (not shown), with an intermediate portion of the cross bolt fastener 148 extending through the gap. According to example aspects, the fastener 120 can be rotatably coupled to an intermediate portion of the cross bolt fastener 148. Note that, in different aspects, other connectors can be employed to allow for rotation of the fastener 120 with respect to the mounting bracket 106, such as, for example, a swivel bolt.
The mounting plate 140 of the mounting bracket 106 can be coupled to the protruding portion 142 of the mounting bracket 106. Example aspects of the mounting plate 140 can define a front surface 140a and an opposite-facing rear surface 140b. The rear surface 140b of the mounting plate 140 can be configured to abut and engage a mounting structure, such as a concrete wall 160, wherein the concrete wall 160 can be part of a larger structure, such as a building. According to other aspects, the pipe support assembly 100 can be mounted to any suitable mounting structure, such as, for example, a joist, a wooden beam or blocking, a steel beam, or a concrete pillar, floor, or ceiling. According to the depicted aspect, the rear surface 140b can define a substantially flat profile to lie against and engage the substantially flat concrete wall 160. In other aspects, the rear surface 140b of the mounting plate 140 can define a non-flat profile. For example, the rear surface 140b can be curved to engage a curved mounting structure or angular to engage an angular mounting structure. The front surface 140a of the mounting plate 140 can be oriented opposite the rear surface 140b of the mounting plate, such that the front surface faces away from the mounting structure.
The mounting plate 140 of the mounting bracket 106 can define one or more through-holes (not shown) extending from the front surface 140a of the mounting plate 140 to the rear surface 140b. A mounting fastener for coupling the mounting bracket 106 to the concrete wall 160 can extend through the though-holes (not shown) to engage the concrete wall 160. For example, as is shown in the depicted example aspect, the mounting fastener can be a concrete wedge anchor 152. The concrete wedge anchor 152 can comprise a threaded rod portion 152a and an anchor portion 152b. The diameter of the anchor portion 152b tapers to a slightly smaller size away from the threaded portion 152a and then tapers back out to match the diameter of the threaded portion 152a at the end of the anchor portion 152b. A wedge clip 158 can be attached around the narrower section of the anchor portion 152b. The anchor portion 152b of the wedge anchor 152 and the wedge clip 158 can pass through the though-hole (not shown) in the mounting plate 140 and be inserted into a passage 162 in the concrete wall 160. In example aspects, the diameter of the passage 162 in the concrete wall 160 can be substantially the same as the diameter of the anchor wedge 152 at its largest diameter. A nut 154 can be threaded onto the threaded portion 152a of the wedge anchor 152 and tightened against the front surface 140a of the mounting plate 140 to secure the mounting bracket 106 against the concrete wall 160. As the nut 154 is tightened, the wedge anchor 152 is drawn partially out of the passage 162, wedging the wedge clip 158 between the wide end of the anchor portion 152b and the walls of the concrete passage 162. In other aspects, the mounting bracket 106 can be fastened to the concrete wall 160 using any other suitable mounting fastener known in the art, such as, for example, bolts, clips, rivets, snaps, adhesives, or welds. According to example aspects, the fastener 120 of each fitting assembly 180 can be threaded and unthreaded with respect to its corresponding fitting 124, such that the length of the pipe support assembly 100 can be selectively adjusted at the first end portion 104a of the brace member 104 and the second end portion 104c of the brace member 104. Allowing for length adjustment on both ends of the brace member 104 increases the range of lengths that can be achieved by the pipe support assembly 100. In one example, it can be desired that pipe 108 be supported twelve inches from a ceiling, and the length of the pipe support assembly 100 is fourteen inches. To reduce the length of the pipe support assembly 100 so that the pipe support assembly 100 can support the pipe 108 twelve inches from the ceiling, each fastener 120 can be selectively threaded one inch deeper into the corresponding fitting 124, reducing the length of the pipe support assembly 100 from fourteen inches to twelve inches.
According to another aspect of the current disclosure, the brace member 104 can be mounted directly to a mounting structure, without the need for a mounting bracket 106. For example, as shown in
As illustrated in
The fitting 1024 can further comprise a fastener for securing the fitting 1024 to the brace member 1004. In example aspects, the fastener can be a set screw 1028. The set screw 1028 can be substantially similar to the set screw 128 described above. Furthermore, a set screw bore 1030 can be defined in the first jaw 1072 of the fitting 1024, extending from an upper surface 1072a of the first jaw 1072 to a lower surface 1072b of the first jaw 1072. The set screw bore 1030 can be substantially similar to the set screw bore 130 described above. The set screw bore 1030 can be threaded to match the threading on the set screw 1028, allowing the set screw 1028 to be screwed into the set screw bore 1030. The set screw 1028, when threaded into the set screw bore 1030, can move towards the second jaw 1074 and can bias the portion of the cylindrical side wall 1064 received within the slot 176 towards the second jaw 1074. The set screw 1028 can be sufficiently tightened such that the side wall 1064 is clamped between the set screw 1028 and the second jaw 1074, preventing movement and removal of the brace member 1004 with respect to the fitting 1024. In various aspects, additional or other fastening devices can be used for attaching the fitting 1024 to the brace member 1004; for example, clips, rivets, snaps, adhesive, welds, or any other fastener known in the art.
The threaded tail end 1020b of the fastener 1020 can adjustably engage a fastener bore 1032 can be formed in the fitting body 1070 of the first fitting 1024. In example aspects, the fastener bore 1032 can be a blind hole, as shown. The fastener bore 1032 can be threaded to match the threading on the tail end 1020b of the adjustable fastener 1020, allowing the fastener 1020 to be threaded with the fastener bore 1032, and attaching the fastener 1020 to the fitting 1024. In example aspects, a centerline axis Cb of the fastener bore 1032 can be substantially aligned with the centerline axis Cp of the brace member 1004, and as such, a centerline axis Cf of the adjustable fastener 1020 can be substantially aligned with the centerline axis Cp of the brace member 104. In such an aspect, the fastener 1020 and the brace member 1004 can be oriented concentrically with respect to one another.
Referring to
As discussed above, in accordance with an example aspect of the disclosure, the rotational coupling of the fitting assembly 180 to the pipe clamp 102 allows the brace member 104 to move relative to the pipe clamp 102, and the rotational coupling of the second fitting assembly 180 to the mounting bracket 106 allows the brace member 104 to move relative to the mounting bracket 106. Such freedom of movement can be desired in instances of seismic events or other events that cause a structure to move (such as the settling of a building), as the pipe support system 100 can move along with the moving structure. For example, in the event of an earthquake, a fire can occur in an affected structure. An indoor sprinkler piping system supported by such a pipe support assembly 100 can move as the structure moves, remaining attached to the structure and operational. In another example, an HVAC piping system can be installed in a structure and can be supported by such a pipe support assembly 100 as described herein. As the structure settles over time, the pipe support assembly 100 can move along with the settling structure, enabling the HVAC piping system to remain attached to the structure and operational.
Moreover, as discussed above, the length of the fitting assemblies 180,1080 described and contemplated herein can be selectively lengthened and shortened. Such adjustability provides the desirable benefit of having a single fitting assembly design capable of supporting pipes and piping systems positioned at varying distances from a mounting structure, making installation easier. For example, an indoor sprinkler piping system can comprise a first pipe to be supported ten inches from a structure and a second pipe to be supported twelve inches from a structure. The same adjustable fitting assembly design can be utilized to support both the first and second pipes at the desired distances from the mounting structure.
