Description
- This application incorporates by reference the disclosure of Japanese Patent Application No. 2005-366322, filed on Dec. 20, 2005.
- This invention relates to a pipe support apparatus and particularly to a vertically adjustable pipe support apparatus for use in supporting a pipe system under the floor of a building.
- A conventional pipe support apparatus is arranged for supporting a pipe at an adjusted elevation and inclination so that a liquid in the pipe can smoothly flow through the supported pipe system. Japanese Patent Application Laid-Open No. 2004-204967 discloses one example of such a pipe support apparatus, which comprises a pair of parallel support pillars erected on a base and a pipe holder attached to the support pillars at a selected elevation. Each support pillar has a series of teeth along the pillar so that the pipe holder can be moved along the teeth and engaged at any selected position along the toothed pillars.
- One application of a pipe support apparatus is to support a water drainage pipe system in which drain pipes are disposed under a floor in a slightly inclined position to ensure smooth and quick water drainage. In some locations, the pipe is supported at a higher position on the pipe support apparatus and the pipe holder is attached at a higher position on the support pillars. In other locations, the pipe holder is mounted at a lower position on the support pillars to support the pipe at a lower position on the pipe support apparatus, and the upper portions of the support pillars are left unused and project upwardly above the pipe.
- These projecting upper portions are unnecessary and awkward, especially when the pipe support apparatus is used under a floor. In a high-rise apartment building, the space under a floor usually has a very small height, such as around 150 mm, so these unnecessary projections can be a nuisance. In addition, in a single-family house in which the under-floor space is narrow but a little larger, utility maintenance or repair sometimes requires personnel to enter into the narrow space under the floor.
- These unnecessary projections may not only be obstacles to the movement of the inspection personnel but may also endanger them in that the projecting ends of the support pillars may hit or scratch the body of the personnel and cause injury. Therefore, these unnecessary and dangerous projections of the support pillars must often be cut off, and the cut-off ends must be covered with rubber caps for safety reasons. This increases the number of procedures and the costs required to install the pipe system.
- Accordingly, an object of the present invention is to provide a vertically adjustable pipe support apparatus that provides easy and safe support for pipes installed under a floor of a building.
- Another object of the present invention is to provide a method of supporting a pipe using a pipe support apparatus.
- According to one form of the present invention, a vertically adjustable pipe support apparatus includes a base and a first and second support pillar mounted in parallel on the base and separated from each other by a distance larger than the diameter of a pipe to be supported. The first and second support pillars support a first and second movable pillar, respectively, for slidable movement along the support pillars to enable the movable pillars to be extended and retracted with respect to the support pillars. A locking mechanism is provided for locking the movable pillars at a desired height along the support pillars. A pipe holder for supporting a pipe is connected between top ends of the movable pillars. Preferably the top of each support pillar is no higher than the top of a supported pipe when the movable pillars are in their fully retracted positions. In addition, the tops of the movable pillars are preferably no higher than the top of a supported pipe. The relative lengths of the support pillars and the movable pillars are not critical. In a preferred embodiment, each movable pillar has a length substantially equal to the length of the corresponding support pillar.
- In a preferred embodiment, the base and support pillars are integrally formed with each other from a single piece of sheet metal, for example. The movable pillars and the pipe holder may also be integrally formed with each other from another single piece of sheet metal.
- In a preferred embodiment, each support pillar has a generally U-shaped cross section and each movable pillar is accommodated within the U-shaped cross section of the corresponding support pillar.
- In a preferred embodiment, the pipe holder is an arcuate member shaped to extend along the circumference of the bottom half of a pipe being supported. For example, the pipe holder may be a generally C-shaped member elastically fitting around a portion of the circumference of a pipe.
- In a preferred embodiment, the locking mechanism comprises a bolt which is threadingly engaged with one of the movable pillars and can be tightened against one of the support pillars.
- According to another form of the present invention, a method of supporting a pipe includes receiving a first portion of the length of a pipe in a pipe holder of a first pipe support apparatus with movable pillars of the first pipe support apparatus at a first height with respect to a base of the first pipe support apparatus, and receiving a second portion of the length of the pipe in the pipe holder of a second pipe support apparatus with movable pillars of the second pipe support apparatus at a second height with respect to the base of the second pipe support apparatus which is higher than the first height.
- A pipe support apparatus according to the present invention avoids the need to have members projecting above the top of a pipe being supported, so the apparatus is easier to install than existing pipe support apparatuses because it does not require projecting portions to be cut off and covered with protective caps. The lack of projecting members also increases the safety of persons inspecting a piping system employing the pipe support apparatus. These features make a pipe support apparatus according to the present invention highly suitable for installation in crowded spaces such as beneath a floor of a building. However, the pipe support apparatus is not restricted to use in any particular environment.
- The present invention will become more readily apparent from the following detailed description of a preferred embodiment taken in conjunction with the accompanying drawings, in which:
-
FIG. 1 is a perspective view of an embodiment of a vertically adjustable pipe support apparatus of the present invention in a fully retracted position in which the movable pillars are fully retracted into the support pillars; -
FIG. 2 is a perspective view of the embodiment ofFIG. 1 in a state in which the movable pillars are partially extended from the support pillars; and -
FIG. 3 is a front view of the embodiment ofFIG. 1 showing a supported pipe in a fully raised and a fully lowered position. - FIGS. 1 to 3 illustrate an embodiment of a pipe support apparatus 1 of the present invention, which comprises a
base 2 and a first andsecond support pillar 3 mounted in parallel to each other on thebase 2 and separated from each other by a distance larger than the diameter D of apipe 4 to be supported. Thebase 2 and the twosupport pillars 3 in this embodiment are manufactured from a substantially U-shaped single piece of sheet metal so that they are integrally formed with each other. Each of the two legs of the U-shaped piece of sheet metal is bent along its length to form one of thesupport pillars 3, each of which has a substantially U-shaped cross section, atop end 3 a, and abottom end 3 b. The leg portions of thesupport pillars 3 have outwardly extendingtabs 5 at theirbottom ends 3 b. The bight portion of the U of the piece of sheet metal is bent at its bottom edge to form an outwardly extendingflange 6 which, together with thetabs 5, forms thebase 2. Eachsupport pillar 3 has alongitudinal slot 7 extending over substantially its entire length. During use of the pipe support apparatus 1, thebase 2 usually sits on a support surface and if desired may be secured to the support surface. For example, thetabs 5 of thebase 2 may have holes for receiving screws of bolts for securing thebase 2 to a support surface. - This embodiment of a pipe support apparatus 1 also comprises a first and second
movable pillar 8 supported by the first andsecond support pillars 3, respectively, for slidable movement along the height of thesupport pillars 3 to extend and retract themovable pillars 8 with respect to thesupport pillars 3. - As shown in
FIG. 3 , in this embodiment, each of thesupport pillars 3 has a length L measured from thebase 2 which does not exceed the height HT measured from thebase 2 of the top T of a supportedpipe 4 when themovable pillars 8 are in their fully retracted position, shown by solid lines inFIG. 3 as well as inFIG. 1 . In other words, the heights H3 of thetop ends 3 a of thesupport pillars 3 are lower than the height HT of the top T of thepipe 4 in this position. Each of themovable pillars 8 has atop end 8 a, abottom end 8 b, and a length substantially equal to the length of thesupport pillars 3. Themovable pillars 8 also have substantially U-shaped cross sections and are slidably received within the U-shaped portions of thesupport pillars 3 so that themovable pillars 8 can be slidably guided by thesupport pillars 3. Preferably the top ends 8 a of themovable pillars 8 do not extend above the top T of a supportedpipe 4. By having the tops of thesupport pillars 3 and themovable pillars 8 always be no higher than the top T of a supportedpipe 4, it becomes unnecessary to cut off any portions of thepillars - The pipe support apparatus 1 further comprises a
pipe holder 9 connected betweentop ends 8 a of themovable pillars 8 for supporting apipe 4. Thepipe holder 9 in the illustrated example is an arcuate, generally C-shaped member extending along the circumference of the lower half of apipe 4 being supported. The cross section of thepipe holder 9 is also substantially U-shaped with the open portion of the U facing downwards towards thebase 2, and thepipe holder 9 and themovable pillars 8 can be manufactured by cutting and bending a single piece of sheet metal so that they are integrally formed with each other. The C-shaped pipe holder 9 has some elasticity so that its mouth can be expanded to accept apipe 4 and return to its original shape to elastically fit around a portion of the circumference of thepipe 4. As shown inFIG. 3 , in order to prevent apipe 4 from becoming easily detached from thepipe holder 9, thepipe holder 9 preferably extends around thepipe 4 for at least half the circumference of thepipe 4, and the size of the mouth of thepipe holder 9 when thepipe holder 9 is grasping apipe 4 is preferably smaller than the diameter of thepipe 4. For example, in the illustrated embodiment, thepipe holder 9 is shown inFIG. 3 contacting the periphery of apipe 4 for approximately 200 degrees around the circumference of thepipe 4, and the distance between the opposing edges of the mouth of thepipe holder 9 is approximately 91% of the diameter D of thepipe 4. - When the
support pillars 3 are at least as long as themovable pillars 8, themovable pillars 8 can be extended from and retracted into thesupport pillars 3 for substantially the entire length of themovable pillars 8. There are no particular restrictions on the lengths of thesupport pillars 3 andmovable pillars 8. However, when the pipe support apparatus 1 has a structure like that of the present embodiment in which thesupport pillars 3 and themovable pillars 8 have substantially the same lengths as each other and thepipe holder 9 has a depth which is at least the radius D/2 of apipe 4 being supported, thesupport pillars 3 will typically have a length at least somewhat larger than the radius D/2 of thepipe 4. In this case, the stroke of movement of themovable pillars 8 relative to thesupport pillars 3 is approximately equal to the radius D/2 of thepipe 4 being supported. - The pipe support apparatus 1 may further comprise a
locking mechanism 10 for releasably locking themovable pillars 8 with respect to thesupport pillars 3 at a desired height along thesupport pillars 3 between a fully extended position and a fully retracted position. In the illustrated embodiment, thelocking mechanism 10 comprisesbolts 11 each extending through theelongated slot 7 in one of thesupport pillars 3 and threadingly engaged into one of themovable pillars 8. Eachbolt 11 can be tightened at its head with a washer against one of thesupport pillars 3.FIG. 1 shows themovable pillars 8 secured by thelocking mechanism 10 in a fully retracted position, andFIG. 2 shows themovable pillars 8 secured by thelocking mechanism 10 in a partially extended position between the fully retracted position and a fully extended position. - The
locking mechanism 10 is not restricted to astructure employing bolts 11 and can have any structure which enables themovable pillars 8 to be releasably locked against movement along the height of thesupport pillars 3. For example, thelocking mechanism 10 may comprise threaded studs extending outwards from themovable pillars 8 through theslots 7 in thesupport pillars 3, and a nut can be mounted on the outer end of each stud. Themovable pillars 8 can then be locked against movement with respect to thesupport pillars 3 by tightening the nuts against the outer surfaces of thesupport pillars 3. - The stroke of the
movable pillars 8 relative to thesupport pillars 3, which equals the range of vertical adjustment of thepipe 4, is the range of vertical movement of thebolts 11 within theslots 7. When themovable pillars 8 are in their fully retracted (lowest) position, thebolts 11 abut against the lower ends of theslots 7, and when themovable pillars 8 are in their fully extended (highest) position, thebolts 11 abut against the upper ends of theslots 7. The solid lines inFIG. 3 illustrate the pipe support apparatus 1 when themovable pillars 8 are in their fully retracted position, and the dashed lines inFIG. 3 show thepipe 4 and thebolts 11 when themovable pillars 8 are in their fully extended position. As can be seen fromFIG. 3 , although the height H3 of the top ends 3 a of thesupport pillars 3 is lower than the height HT of the top T of a supportedpipe 4 when themovable pillars 8 are in the fully retracted position, thepipe holder 9 and thepipe 4 can be elevated further beyond the top ends 3 a of thesupport pillars 3. In this embodiment, when themovable pillars 8 are in their fully extended position, the bottom of thepipe 4 is higher than the tops of thesupport pillars 3. - In the illustrated embodiment, the
base 2 and thesupport pillars 3 are integrally formed from a single piece of sheet metal, and themovable pillars 8 and thepipe holder 9 are also integrally formed from a single piece of sheet metal, so the apparatus can be easily and economically manufactured using simple metal working techniques. However, the apparatus is not restricted to being formed from two one-piece members, and it is not restricted to being formed from sheet metal. - A pipe, such as a plastic pipe, can be supported in a desired orientation with respect to the horizontal by one or more pipe support apparatuses according to the present invention. Frequently a pipe will be supported at two or more locations along its length by a pipe support apparatus at each location, but depending upon the length and weight of the pipe and what it is connected to at its ends, a pipe may be supported by a pipe support apparatus at a single location along its length. When a
pipe 4 is supported by two pipe support apparatuses 1 according to the present invention having the structure of the embodiment ofFIGS. 1-3 , each end of thepipe 4 can be force-fit into thepipe holder 9 of one of two pipe support apparatuses 1 spaced from each other in the lengthwise direction of thepipe 4. The heights of themovable pillars 8 with respect to thesupport pillars 3 of each pipe support apparatus 1 can be set by the lockingmechanisms 10 to give the pipe 4 a suitable angle of inclination. The heights of themovable pillars 8 can be set either before or after thepipe 4 is engaged with thepipe holders 9. If desired, each of the pipe support apparatuses 1 can be secured at itsbase 2 in any convenient manner to a suitable support surface, either before or after thepipe 4 is engaged with thepipe holders 9. If the two pipe support apparatuses 1 are on a level surface, apipe 4 can be inclined with respect to the horizontal by setting themovable pillars 8 of the two pipe support apparatuses 1 at different heights, while apipe 4 can be supported with zero inclination by setting themovable pillars 8 of the two pipe support apparatuses 1 at the same height as each other. To give thepipe 4 the maximum angle of inclination, one of the pipe support apparatuses 1 can have itsmovable pillars 8 in the fully retracted position shown inFIG. 1 , and the other pipe support apparatuses 1 can have itsmovable pillars 8 in the fully extended position shown inFIG. 3 .
