Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention generally relates to devices used in the installation and mounting of elongated tubular material such as pipes, conduit and wire over and across a surface, and more particularly to installation and mounting of such items upon a generally horizontally disposed surface such as a roof or floor.  
         [0003]     2. Background Information  
         [0004]     Many features of modern construction provide convenience by allowing a party to simply and easily access items from a distant location. Examples of such devices include plumbing, heating, ventilating and air conditioning systems. In many of these instances needed materials such as natural gas, electricity, water, and other items are transported from one location to another through a conduit. These conduits must be permanently attached in one location so as to support the conduit while preventing the conduit from being damaged or moved out of a desired alignment and position.  
         [0005]     One of the ways in which this is done is through mounting devices that are mounted or secured in a desired location so as to support and maintain the stability of these devices. In mounting or securing such items there are several considerations that must be taken into account. Some of these considerations include: the weight of the pipes on the roof, the possible damage to the roof and the environmental considerations in which the system will be placed. Mounting systems must have sufficient strength so as to support a designated item in a desired position and orientation upon a roof. Mounting systems must also be of a material that will not cause damage to the roof or floor, or other surface that underlies the position wherein the mounting system is placed. If damage to the surface were to occur, for example in the instance of a roof, damage to the underlying roof could cause additional damage to the interior of the building.  
         [0006]     Other considerations that must also be taken into account include providing a means for allowing the general slope of the conduit to be maintained and adjusted in such a way so as to allow the desired flow and positioning of materials through the transport tube. In some instances, such as those occurrences wherein a party is dealing with gravity fed drain lines, an appropriate slope must be accommodated so as to ensure the proper drainage of the pipes from a first location to a discharge area. In other modifications the general level of the pipe must be left level so as to ensure the appropriate rate of flow of materials through these devices. In other applications the appropriate positioning of the device is crucial to the protection and function of the conduits and the materials passed there through.  
         [0007]     Another problem that occurs in the prior art is that the weight of the blocks that are placed upon the roof in order to ensure the stability of these conduits are many times burdensomely heavy and thus difficult and bulky for a user to move and install. Another feature that exists in the prior art is that some of the devices utilized in the prior art have inherent limitations because of their size and configurations and do not allow for the placement of multiple pipes or conduit to be run over a designated distance.  
         [0008]     Various prior art systems have attempted to address these problems. However, each of these systems has had inherent problems associated with them. One system that is employed in the prior art utilizes the attachment of the tubing to wooden planks with unfinished metal clamps. This system has many limitations. One problem is that significant damage can be caused to the roofing material by wooden planks. This damage is incurred not only from the weight of materials but also by movement of the planks along the surface of the roof as the conduit connected thereto expands and contracts in response to various thermal conditions. Furthermore, in climates where the devices are exposed to water in various forms, the increased exposure to moisture causes the wood to rot and the unprotected metal to rust and therefore requires frequent replacement and repair. Another problem that exists in such an embodiment is that the wooden planks must be shimmed or cut in order to accommodate various height and slope requirements depending upon the conduit that is being mounted. This requires that an installer not only bring all of the bulky wooden pieces and the metal connection parts with him/her on to the roof, but that he/she also bring tools with them so that they can cut, modify and construct bracing of various heights so as to allow for the proper installation of the conduits upon the designated surface.  
         [0009]     Therefore what is needed is an improved system for mounting and placing conduits and pipes upon a building structure. What is also needed is a system and device that allows for variable forms of flexibility with pieces that are easy to carry, simple to use and easy to install. What is also needed is a device that provides vertically and horizontally stable support elements connected to a connection device that allows for the placement of multiply variable conduits that are attached to support devices through simple means with limited use of tools. Accordingly, it is an object of the present invention to provide these items.  
         [0010]     Additional objects, advantages and novel features of the invention will be set forth in part in the description which follows and in part will become apparent to those skilled in the art upon examination of the following or may be learned by practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.  
       SUMMARY OF THE INVENTION  
       [0011]     The present invention is a system and device for installing and mounting conduit upon a surface such as a roof. The system is comprised of at least one support unit, such as a support block, that is configured to support at least one pipe. The support rail has a track and an adapter for connecting a piece of conduit to a support rail. These pieces are configured to work together to provide a mounting system with significant advantages over other devices that exist in the prior art.  
         [0012]     The support block has a body with a base and an upper portion. The body of the support block is generally hollow and defines an internal cavity that is configured to receive an upper portion of another support block within the hollow body. In the preferred embodiment, this configuration is accomplished by providing a support block with a generally tapered configuration wherein the base covers a larger area than the upper portion. The upper portion further defines a channel positioned within an upper portion of the support unit. The channel of the device is then configured to receive a support rail therein.  
         [0013]     The generally hollow support block is hollow and defines an internal cavity within the support block. The internal cavity is configured to receive an upper portion of a second support block. The internal cavity and the second support block are configured so that when a second support block is placed in a first orientation over a first support block, the first support block and the second support block nest together, with the second support block fitting inside of the first support block. These devices are also configured so that when the first support block is positioned in a second orientation over a second support block, the first and second support blocks do not nest but are positioned together in a generally stable vertically spaced orientation.  
         [0014]     In the preferred embodiment, the support blocks are assisted in holding themselves in a generally vertically oriented position by generally vertically oriented ribs or projections that extend from the upper portion of the support block. These generally vertically oriented projections are configured to stabilize the support blocks when the support blocks are positioned in the previously described spaced stacked orientation. In the preferred embodiment, these support blocks also include at least one generally horizontally oriented projection. These generally vertically oriented projections are each configured to interact with an inner portion of a compatibly configured inner portion of another block so as to hold the vertical blocks in a stable, vertically spaced orientation.  
         [0015]     These blocks are preferably made of a high-density UV resistant plastic material, such as ABS, polycarbonate, fiberglass mix or any other suitable material that achieves the necessary functions of the device. These devices prevent damage to the underlying roof surface, while at the same time having sufficient strength so as to support loads of up to 100 lbs. These blocks are also relatively lightweight, which allows a party utilizing the blocks to carry a stack of nested blocks together upon a roof for placement. While upon the roof, the blocks can be removed from their nested position and assembled and placed in a desired position and orientation. The support blocks of the present invention are so configured so that in the event that a block at a raised height is required, such an elevated block arrangement can be obtained by removing a first block from a nested position upon a second block and rotating the first block 90°, and then replacing the first block over the second block. Such a configuration allows for a rise of a predetermined vertical height adjustment and facilitates the ease and use of the device upon a roof or other designated surface.  
         [0016]     In use, once the blocks are in place, a support rail is placed within the channel in the top portion of the support block, and various attachments may be inserted into the track portion of the portion rail. The conduit is then connected to or brought into contact with the various attachment devices and connected. Such a system provides a significant improvement over the prior art in that it eliminates the major disadvantages of the prior art system and devices that have been previously described and discussed.  
         [0017]     The purpose of the foregoing Abstract is to enable the United States Patent and Trademark Office and the public generally, and especially the scientists, engineers, and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection, the nature and essence of the technical disclosure of the application. The Abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.  
         [0018]     Still other objects and advantages of the present invention will become readily apparent to those skilled in this art from the following detailed description wherein I have shown and described only the preferred embodiment of the invention, simply by way of illustration of the best mode contemplated by carrying out my invention. As will be realized, the invention is capable of modification in various obvious respects all without departing from the invention. Accordingly, the drawings and description of the preferred embodiment are to be regarded as illustrative in nature, and not as restrictive in nature.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0030]     While the invention is susceptible of various modifications and alternative constructions, certain illustrated embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.  
         [0031]     The present invention is a system for mounting pipes upon a building roof or structure.  FIGS. 1-10  of the present invention show this preferred embodiment of the invention both together as well as in its individual pieces as they are described in the present invention. Referring first to  FIG. 1 , the support block  10  used in the present invention is shown. The support block  10  has a body (which is also  10 ), which includes an upper portion  14 , a channel  12  and a base  16 . The body  10  is generally hollow and defines an inner cavity that is compatibly configured to receive a second unit therein as is shown in  FIGS. 2-5 . This allows for the stacking of these support blocks  10  in varied configurations to achieve various desired results.  
         [0032]     In the preferred embodiment, the support blocks are made of a high-density ABS plastic that is UV resistant and allows for maximum strength as well as resistance to wear. This also ensures that the devices are relatively lightweight and easy to carry. The nesting feature of the present invention allows multiple numbers of these devices to be carried in a stacked configuration thus allowing increased ease in transporting these devices from one location to another.  
         [0033]     The support blocks  10  of the present embodiment also comprise a first set of projections or support ribs  18  that extend in a generally vertical orientation extending from just below the base along the upper portion  14 . This first set of projections or support ribs  18  are configured to nest within compatibly configured portions of the hollow internal cavity of another compatibly configured support block  10 . In the preferred embodiment, the body  10  is generally tapered as it extends from the base  16  to the top of the upper portion  14 . This facilitates the ease of stacking the various devices one upon the other.  
         [0034]     The preferred embodiment of the present invention also includes a second set of projections or support ribs  20  and a third set of projections or support ribs  22 . These projections  18 ,  20  and  22  provide resistance and bracing against horizontal movement when two of the support bodies  10  are placed upon one another in a generally vertical orientation.  
         [0035]     Referring now to  FIG. 2 ,  FIG. 2  shows two of the blocks  10  of the present embodiment. One is shown in a first orientation and the other in a second orientation. When the two devices are stacked one upon the other, they result in the generally vertically spaced stacking orientation shown in  FIG. 3 . In the preferred embodiment, the distance from the base  16  of the first device  10  to the base  16  of the second device  10 ′ is approximately one half inch in the nested position, and a space of about two inches when these devices are stacked in the vertically spaced configuration. While these measurements are shown and described in the present embodiment, it is to be distinctly understood that the invention is not limited thereto but may be variously embodied to include a variety of other features and configurations. This ability allows a user to accommodate irregular roof surfaces by turning and stacking these support blocks thus moving them from a nested position (shown in  FIG. 5 ) to this generally spaced orientation (shown in  FIG. 3 ). This enables a user to progressively increase the height of these blocks  10  by simply utilizing the blocks themselves, and does not require the additional use of other spacing devices or shims as is taught in the prior art.  
         [0036]     While additional spacing devices are not required, their use is similarly not prohibited by the use of the present invention. It is to be distinctly understood that the present invention does not exclude additional spacing devices such as shims from use with the present invention.  
         [0037]     Referring now to  FIG. 4 , a view of two samples of the present invention is shown oriented in the same direction. These devices, when oriented in the same orientation and then stacked, result in a nesting configuration as shown in  FIG. 5 . This nesting stacked configuration allows multiple devices  10  to be stacked one on top of each other and carried from one location to another. When arriving at the second location, if an increase in height is necessary, this can be achieved by simply lifting the top block  10 ′ from its nested position on top of a bottom block  10 , rotating the block ninety degrees and replacing this top block  10 ′ on top of the block beneath  10 . When this occurs, the blocks  10 ,  10 ′ are vertically stacked in a vertically spaced orientation as is shown in  FIG. 3 . This then allows the user to attach the remaining portions of the system  100  to the block  10 ,  10 ′ as may be required.  
         [0038]      FIG. 6  shows a support rail  102  that defines a track  103  and which is configured to fit within the channel  12  of the support block body  10 . When placed within this support block body  10 , the track  103  may be utilized to span distances and extend outward and beyond the mounting block  10  itself. This provides a significant advantage in that rather than requiring a very large mounting block, as is shown in some of the prior art embodiments, the present invention can simply use two of the support blocks  10  and extend a track  103  to the desired length between these two devices so as to form a so called bridge that can then hold attachments connected thereto. This configuration allows the various pipes to be held in a desired mounting position. The support rail  102  has a track  103  which also defines apertures  110  or other means for permanently attaching the rail  102  to the support block  10  through a traditional fastening device such as a screw.  
         [0039]     While this is described as the preferred embodiment of the invention, it is to be distinctly understood that the present invention is not limited thereto but may be variously embodied within the scope of the claims. Therefore, the limitation of the track  103 , support block  10  and attachment means are intended to be merely illustrative in nature and not as restrictive. The system of the present invention further comprises various attachment devices (shown in  FIGS. 7, 8 ,  8 A and  9 ) that can be attached to the track  103  and the blocks  10  to hold the various pipes  120  in a desired orientation. While one size of this support rail is shown in  FIG. 6 , it is to be distinctly understood that the invention is not limited thereto but may be variously embodied to include a variety of other features and configurations depending upon the necessities of a user. These configurations include those situations where a single rail is generally centrally positioned over a single support block  10 , as well as other instances where a rail  103  is bridged over a pair of support blocks  10 .  
         [0040]      FIG. 7  shows a removable adapter  104  that is configured to be placed within the track  103 . In this preferred embodiment this connection is achieved by a “snap-in” connection. This snap-in connection is achieved by tabs that are configured to grasp a portion of the rail  102 , and hold the adapter  104  in a desired position and orientation. The present invention also includes a stationary adapter  107  that is configured to hold a pipe  120  of a desired shape therein. These devices are configured so that the device can simply snap into these devices and be prevented from any vertical or horizontal movement while still allowing the pipe  120  to expand and contract in a longitudinal direction along the length of the pipe  120 , which would be inserted therein.  
         [0041]     Another embodiment of the present invention that shows a similar operation is shown in  FIG. 8 .  FIG. 8  shows another adapter  104 ′, which has a snap-in base  105  and a roller  106  which is configured for placement within the snap-in base  105 . The roller  106  has a generally hourglass shape that allows for the placement of up to two pipes within the valleys  112 , within the roller  106 . In this embodiment, as the pipe moves, the roller simply rolls. However, the configuration of the device prevents the movement of the device in a vertical or horizontal orientation but allows the pipe to expand and contract in a generally longitudinal direction along the length of the pipe.  FIG. 8A  shows a similar configuration wherein a single hourglass shaped roller is rollingly connected to a more permanently affixed base. In addition to this embodiment a variety of other devices, shapes and configurations can also be utilized with the connection bases  105 ,  114 , to connect and maintain pieces of material in a desired shape and orientation.  
         [0042]     In addition to this embodiment, other variations of these attachment devices are also considered to be a part of the device. In other embodiments single hour glass pieces connected at a generally centrally positioned core may be utilized rather than the double hourglass configuration that is shown in  FIG. 8 .  
         [0043]      FIG. 9  shows a generally vertically oriented attachment device  108  which may be connected to the support block  10  so as to provide a vertically adjustable pipe connection device. Such a configuration is of particular assistance for use with a gravity dependent drain or other piece of conduit that requires the maintenance of a desired slope between two points. This vertical attachment device further allows a device to accommodate pieces of conduit and tubing that are oriented and arranged as various desired slopes and positions. An example of such a device is shown in  FIG. 9  of the present embodiment.  
         [0044]      FIG. 10  shows one possible combination of the various elements of the system  100  of the present invention in use. While the preferred embodiment of the present invention is shown, it is to be understood that the invention can be variously configured to be utilized and would still function within the scope of the present invention. This includes embodiments where the device can rotate and stack in various lengths, while in the preferred embodiment it is two inches. This embodiment allows the device to carry more than one pipe and can be used with or without the strut track that runs in between. In addition to being stacked, these devices can be glued together for additional support, saddle step into the strut and provide side pressure on the pipe.  
         [0045]     While there is shown and described the present preferred embodiment of the invention, it is to be distinctly understood that this invention is not limited thereto but may be variously embodied to practice within the scope of the following claims. From the foregoing description, it will be apparent that various changes may be made without departing from the spirit and scope of the invention as defined by the following claims.
