- the height H1 (FIG. 2) of the shoulder 168 equals the wall thickness T of the overlying wall 60 . Consequently, as illustrated in FIG. 7, when the chambers 10 and 110 are coupled together, the top surfaces 200 and 202 of the front and rear sections 52 and 152 follow a single smooth curve interrupted only by the bead 56 , projections 170 , and pocket 180 .

- the radially-extending post 170 extends downward from the overlying wall 60 , instead of upward from the underlying wall 160 as shown in FIG. 2.

Also, although one projection 80 , two posts 170 and two notched structures 90 are shown in the example, different numbers of each structure and different suitable locations for each structure are possible.
Abstract
Description
- The present invention relates to leaching chambers.
- A leach field is used to disperse a fluid into the ground. The fluid is typically effluent from a septic tank. The leach field includes a series of leaching chambers, coupled in series and buried in the ground. A pipe conveys the effluent from the septic tank to the leach field, where the effluent spreads through the series of chambers that are oftentimes coupled end to end. Each chamber has perforated side walls and an open bottom through which the effluent escapes to be absorbed into the surrounding soil.
- Each chamber must support the weight of the soil above it, along with anything resting on the soil, such as a vehicle. Therefore, the chamber walls are typically corrugated to increase weight bearing strength.
- FIG. 1 is an exploded perspective view of a first leaching chamber according to the present invention;
- FIG. 2 is a perspective view of a portion of the first leaching chamber and of a second such leaching chamber;
- FIGS.3-5 are sectional views of the leaching chambers of FIG. 2, shown sectioned along line 3-3 of FIG. 2 and in different orientations relative to each other, with the orientations corresponding to successive steps in a process of coupling the chambers together;
- FIG. 6 is a sectional view of the leaching chambers, shown sectioned along line3-3 of FIG. 2 and coupled together; and
- FIG. 7 is a view similar to FIG. 6, with the leaching chambers shown sectioned along line7-7 of FIG. 2.
- An embodiment of the invention is a leaching chamber. The leaching chamber is configured to be coupled in series to another such leaching chamber located forward of the chamber and to yet another such leaching chamber located rearward of the leaching chamber. The leaching chamber comprises a conduit defining a cavity. The conduit includes a front section having an overlying wall and a rear section having an underlying wall. The overlying wall is configured to overlie the underlying wall of the forward chamber when the chambers are coupled together. The underlying wall is configured to underlie an overlying wall of the rearward chamber when said chambers are coupled together. A projection extends from the front section of the conduit. A pocket is located at the rear section of the conduit. The projection is configured to be received by the pocket of the front chamber, and the pocket is configured to receive the projection of the rear chamber. A notched structure defines a notch that is spaced from the front edge of the front section. The notched structure is configured to capture in the notch the underlying wall of the forward chamber when the chambers are coupled together.
- Preferably, the pocket is configured to enable the projection of the forward chamber to pivot relative to the pocket when the projection is received by the pocket, so as to enable the forward chamber to pivot into and out of a coupled position. The notched structure is configured to enable the notch to swing into a position in which the notch captures the underlying wall of the forward chamber. The leaching chamber further comprises a hole in the overlying wall and a post extending radially outward from the underlying wall. The hole is configured to receive the post of the forward chamber when the chambers are coupled together. Correspondingly, the post is configured to be received by the hole of the rearward chamber when the chambers are coupled together.
- Another embodiment comprises first and second chambers. The chambers include coupling structures that prevent the uncoupling of the chambers through translational movement of the chambers. Instead, the coupling structures enable the uncoupling to be achieved through a pivoting motion of the first chamber relative to the second chamber.
- The
apparatus 6 shown in FIG. 1 has parts which, as described below, are examples of the elements recited in the claims. - The
apparatus 6 comprises afirst leaching chamber 10. Thechamber 10 is used to disperse a fluid, such as effluent from a septic tank, into the ground. In its installed position, thechamber 10 is coupled in series with other such leaching chambers to form a leach field that is buried in the ground. The chambers may be positioned both end-to-end and side-to-side. Anend 12 of thechamber 10 is capped with anend cap 16, which has an opening to receive the end of apipe 18. Thepipe 18 conveys the effluent from the septic tank to the leach field, where the effluent spreads through the series of chambers. Thefirst chamber 10 comprises afirst conduit 20 with anopen bottom 22 andopenings 24 through which the effluent escapes to be absorbed into the surrounding soil. - The
first conduit 20 is an arched wall extending about acentral axis 30 to define an axially extendingcavity 36. Theconduit 20 is corrugated in that it comprises an axially extending alternating series ofperforated crowns 44 andvalleys 46. Thecrowns 44 andvalleys 46 are arched and separated from each other by radially-extendingwalls 47. Thevalleys 46 are reinforced with axially-extending and radially-extendingexternal ribs 48. Correspondingly, thecrowns 44 are reinforced with axially-extending and radially-extending internal ribs 49 (FIG. 3). - As shown in FIG. 2 the
frontmost crown 50 includes afront section 52. Thefront section 52 includes afront edge 54 defined by abead 56. Thefront section 52 also includes anoverlying wall 60 extending rearward from thefront edge 54. Theoverlying wall 60 is arched, with an open bottom end 62 (FIG. 1) and an oppositetop side 64 having acentral peak 66. - Two
holes 70 in theoverlying wall 60 are located symmetrically about thecentral peak 66 at thetop side 64 of theoverlying wall 60. Aprojection 80, in this example a tongue, extends forward from and coplanar with thefront section 52 at thecentral peak 66. - Two
notched structures 90 extend radially inward from thefront section 52, symmetrically spaced about thecentral peak 66. The notched structures are formed from axially-extendingreinforcement ribs 92 that reinforce theoverlying wall 60, and are extensions of ribs that reinforce thecrowns 44. Thenotched structures 90, which include thebottom surface 94 of theoverlying wall 60, definenotches 96 that are spaced axially rearward from thefront edge 54. In molding thechamber 10, formation of thenotches 96 may be facilitated by incorporating holes in thefront section 52 above thenotches 90 to make room for a core. - A portion of a
second leaching chamber 110 is also shown in FIG. 2. Thesecond chamber 110 is like thefirst leaching chamber 10. Consequently, each feature described with reference to thesecond chamber 110 is also included on thefirst chamber 10. A portion like the portion of the second leaching chamber shown in FIG. 2 is positioned at the opposite end, the end not show of the first leaching chamber. Thus, each leaching chamber includes both afront section 150 and arear section 152, as discussed in greater detail below. - The
second chamber 110 includes asecond conduit 120 extending about acentral axis 130. Like thefirst conduit 20, thesecond conduit 120 is corrugated, withcrowns 144 andvalleys 146 separated by radially-extendingwalls 148. - The
rearmost crown 150 of thesecond chamber 110 includes arear section 152 with arear edge 154. Therear section 152 includes anunderlying wall 160 extending forward from therear edge 154. Theunderlying wall 160 is configured to underlie the overlyingwall 60 of thefirst chamber 10 when thechambers wall 60, theunderlying wall 160 is arched, with atop side 164 having acentral peak 166. Theunderlying wall 160 is separated from the remainder of therear section 152 by a rearward-facingshoulder 168. The radially-extending height H1 of theshoulder 168 equals the wall thickness T of theoverlying wall 60 of thefirst chamber 10. - Two
posts 170 extend outwardly from theunderlying wall 160 and are located symmetrically about thecentral peak 166 at thetop side 164 of theoverlying wall 160. Theposts 170 are configured to be received by theholes 70 of thefirst chamber 10 when thechambers - A
pocket 180 is located at therear section 152. Thepocket 180 is configured to receive theprojection 80 of thefirst leaching chamber 10 when the leachingchambers outside opening 182 of thepocket 180 is defined in theshoulder 168. Thepocket 180 is raised slightly above theshoulder 168 on thecrown 144. In addition, thepocket 180 has an open bottom, which is useful in joining thefirst chamber 10 to thesecond chamber 110, as discussed below. - The first step in coupling the
chambers second chamber 110 lies horizontally on the ground. Thefirst chamber 10 is oriented such that theprojection 80 is near and directed obliquely toward thepocket opening 182. Next, as shown by anarrow 184, theprojection 80 is translationally moved toward and into thepocket 180. This continues until thefront edge 54 abuts theshoulder 168, as shown in FIG. 4. The point of abutment on theshoulder 168 serves as apivot point 186 in the following step. - As indicated by
arrow 190 in FIG. 5, thefirst chamber 10 is pivoted downward about thepivot point 186. Concurrently, the following things happen. Theprojection 80 pivots upward about thepivot point 186, as indicated by anarrow 192. Theholes 70 move downward and receive theposts 170. Also, the notchedstructure 90 swings into a capturing position in which theunderlying wall 160 is captured in thenotch 96. As the notchedstructure 90 swings downward, therear edge 154 of theunderlying wall 160 rubs against and bends thefront edge 194 of the notchedstructure 90 until the notchedstructure 90 snaps into the capturing position. In a preferred embodiment,edge 194 has a resiliency to allow it to substantially maintain its original shape after theunderlying wall 160 is captured innotch 96. - FIG. 6 shows the
chambers front section 52 thefirst chamber 10 relative to therear section 152 of thesecond chamber 110 is limited, as follows. Theposts 170 are captured in theholes 70. This limits axial movement of thefront section 52 away from therear section 152. Also, theunderlying wall 160 is captured in thenotch 96. This limits radially-inward and radially-outward translational movement of theunderlying wall 160 relative to theoverlying wall 60. Radially-outward movement of theunderlying wall 160 is also limited by abutment of theprojection 80 against thetop wall 196 of thepocket 180. Different modes of movement are also limited or deterred in other ways as evident to those of skill in the art. In each description above of limiting translational movement, the extent of movement that can occur is a function of the clearance, if any, between abutting structures and the flexibility of those structures. - Consequently, the
posts 170 captured in theholes 70, theprojection 80 captured in thepocket 180, and theunderlying wall 160 captured in the notchedstructure 90 all deter uncoupling of the front andrear sections rear sections pocket 180 has theupper wall 196 that limits radially outward movement of theprojection 80, thepocket 180 lacks a lower wall or other structure that would prevent downward pivoting of theprojection 80 within thepocket 180. - In fact, the
posts 170 and holes 70 in combination with theprojection 80 andpocket 180 not only enable, but require the coupling and uncoupling to be achieved through a pivoting motion of thefirst chamber 10 relative to thesecond chamber 110 because theprojection 80 is spaced forward theposts 170. At the beginning of the coupling process, depicted in FIG. 3, theprojection 80 is directed downwardly into thepocket opening 182 while the overlyingwall 60 remains sufficiently tilted upwardly and raised to clear thepost 170. The inward movement ends when thefront edge 54 abuts theshoulder 168. At that point, thehole 70 slips over thepost 170 to allow theoverlying section 60 to pivot downwardly. Similarly, in the uncoupling process, with the axially-extendingprojection 80 vertically captured in theopening 182, thefirst chamber 10 is pivoted upwardly to raise theoverlying wall 60 sufficiently to clear thepost 170. - As shown in FIG. 6, the height H2 of the
notch 96 is greater than the thickness T of theunderlying wall 160 captured by thenotch 96. Furthermore, thenotch 96 is axially spaced from thefront edge 54. These factors enable thenotch structure 90 to swing into the capturing position without being blocked by theunderlying wall 160. The swinging movement is hindered, but not prevented, by therear edge 154 of theunderlying wall 152 rubbing against thefront edge 194 of the notchedstructure 90, because the notchedstructure 90 bends to accommodate the swinging movement. - As mentioned above, the height H1 (FIG. 2) of the
shoulder 168 equals the wall thickness T of theoverlying wall 60. Consequently, as illustrated in FIG. 7, when thechambers top surfaces rear sections bead 56,projections 170, andpocket 180. - In the above described embodiment, as shown in FIG. 2, each of the overlying and
underlying walls wall 60 has thehole 70 and the axially-extendingprojection 80. Theunderlying wall 160 also has a hole, referred to thepocket opening 182, and a radially-extending projection, referred to as thepost 170. - However, in an alternative embodiment, both the axially-extending and radially-extending
projections wall 60, and bothholes underlying wall 160. In such an embodiment, the radially-extendingpost 170 extends downward from the overlyingwall 60, instead of upward from theunderlying wall 160 as shown in FIG. 2. Other positions may also be utilized for theposts 170 and holes 70. - As shown in FIG. 1, the
first chamber 10 has twolower holes 210 and two correspondinglower posts 220, that are similar to theupper holes 70 andupper posts 170 described above. In the process of coupling thechambers first conduit 20 is pivoted downward, its side walls are bent slightly to enable thelower holes 210 of thefirst chamber 10 to receive thelower posts 220 of thesecond chamber 110.
