Abstract
The invention is concerned with an automatic down-pipe extension assembly for use on the bottom end of a vertically positioned down-pipe. Water collecting in a bag located within the assembly actuates the pivoting of a discharge pipe from a vertically stored position to a substantially horizontal in-use position, thereby permitting discharge of water remote from a building foundation.
Description
2163q6:9 The invention relates to apparatus adapted to discharge water, draining from the roof of a building via conventional eavestrough and down-pipe assembly. More particularly, the invention is concerned with an assembly which automatically extends as the drain pipe fills with ; water to deposit or discharge the water at a point remote from the building, thus avoiding accumulation of water close to the foundation of that building.
Various attempts have been made in the past to overcome this potentially serious problem. Two well known methods include the use of a fixed extension tube attached directly to the bottom of the down spout or pipe to extend the distance away from the wall, the second method being the provision of an automatically unrolling plastic tube which extends under pressure of water. Such tubes are generally apertured along their length to permit controlled discharge of water over a fairly broad area and in some instances are spring loaded such that as water pressure decreases the tube rewinds back into a stored position adjacent the lower end of the down-pipe.
There are obvious disadvantages to the above disclosed arrangements. Firstly, the permanently fixed extension, interferes for example with grass cutting and garden maintenance, and has to be continually removed and replaced. This type of system also cannot be per~itted to ~ 2163~69 extend over driveways or sidewalks. The plastic tube arrangement after continuous use has been found not to rewind properly, is susceptible to weather damage and blockage by leaves and other matter drawn off the roof by raln.
It is also conventional to utilize an extension which is pivotally attached to the lower end of the down spout and can be manually rotated from the upper vertically stored position to the substantially horizontal extended position where it can discharge water away from the lower end of the down spout. Examples of arrangements such as this can be found in U.S. Patents Nos. 2,975,805 and 3,316,928. Also, Canadian Patent No. 1,188,476, which issued to Busat on the 11th of June 1985, and Canadian Patent No. 1,169,216, which issued to MacDonald et al on June l9th, 1984 disclosed similar systems. The obvious disadvantages of these prior arrangements is the necessity for the homeowner to be there to position the extension when it rains, which occasionally is not possible.
A further solution to the basic problems of the prior art was proposed in Canadian Patent No. 1,022,320 which issued to Carl H. Felsen on December 12, 1977. Eelsen conceived of a manual or automatic drainage device for pivotal attachment to the down spout. This "automatic"
system contemplated utilizing an electric motor which could be actuated by humidity or an in-house switch. This device, however, was extremely expensive to manufacture and maintain, subject to obvious corrosion problems, and again relied on manual actuation.
Accordingly, there still exists a requirement for a simple, inexpensive system which can automatically be moved to an extended discharge position from a vertical storage position, and the object of this invention is to satisfy this requirement.
Accordingly, the invention is directed to an automatic down-pipe extension assembly for use on the bottom end of a vertically positioned down-pipe which comprises an elbow, adapted an upper end for attachment to the down-pipe, in the principle embodiment this elbow being apertured on its underside a substantial portion of its length, to a point adjacent the upper end. A bag is provided, loosely positioned within the elbow, the bag having a first open end adapted to be attached at the upper end of the elbow such that water may enter the bag from the down-pipe. This bag is further provided with an enlarged section adjacent its end opposite the first open end, and a second open end adjacent that enlarged section.
The second open outlet end being closed by a draw string.
A discharge pipe extension coupler is attached to the elbow for pivotal movement and that coupler is attached to 2163~69 a discharge pipe extension.
An activator is provided pivotally attached at one end to the upper end of the elbow and connected at the other end to the bag, via the draw string. This activating system further includes an arrangement for holding the discharge pipe essentially in a vertically stored position and means for contacting the discharge plpe and substantially applying pressure to that discharge plpe .
In operation, commencing when the discharge pipe is in the upper stored position, water entering and filling the bag, causes the activating mechanism to pivot thereby forcing the coupler and discharge pipe outwardly and downwardly while at the same time releasing tension on the ; 15 draw string to permit opening of the bag thus permitting flow of water through the system.
The invention will now be described by way of example only, reference being had to the accompanying drawings in which:
Figure l is a perspective view of the down-pipe extension in accordance with a preferred embodiment the present invention shown in a vertical, stored position;
Figure 2 is a perspective view of the down-pipe extension according to Figure 1, in its extended and water discharging position;
2163~69 Figure 3 is a perspective view of the extension and coupler assembly according to Figure 1;
Figure 4 is a detailed perspective view of the activating mechanism according to Figure 1, the extension pipe being removed for clarity;
Figure 4A is a diagram of the bag configuration of the present invention;
Figure 5 is an end view of the activating mechanism according to Figure 4 taken in the direction of arrow "A"
(Figure 4); and Figure 6 is a perspective plan view of the activating mechanism according to Figure 4, looking in the direction of arrow "B", (Figure 4).
With reference to the drawings, the down-pipe extension assembly, generally indicated at 10, is mounted at the lower end of a conventional down-pipe or spout 11, which is conventionally attached to the outside wall 12 of a building.
The extension assembly 10 comprises a discharge spout coupler 13; an elbow 14; an activating mechanism 15 which includes a water bag 16 (see Figure 4 and 4A). The discharge spout coupler 13, (Figure 3), is a elongate channel member, rectangular in cross-section, having a bottom 17i sides 18 and an open top. The sides 18 towards outer end 18A of the coupler 13 are reduced in vertical 2163~69 height to allow insertion into a discharge pipe extension 19 (shown in phantom outline). The sides towards the front end 20 of coupler 13 are of increased height, to accept the bottom end of elbow 14, to which it is pivotally attached at 21.
Elbow 14, as can be seen from Figure 4, has a section removed from its lower surface, from the end 22 to a point 23 approximately 3/4 the radius of the elbow curvature.
The elbow 14 is pivotally connected at 21 to coupler 13, thus permitting pivotal movement from the substantially vertical stored position ~Figure 1), to the in-use, extended position (Figure 2).
A flexible bag 16, preferably of waterproof material, - is located within elbow 13, (Figure 4). The major open end 27 of bag 16 being attached at and around the joint 25, between elbow 13 and the down-pipe 11. The bag being loosely contained within elbow 13 but configured so that the lower end of the bag is enlarged at 26 (see Figure 4A), such that it can contain a substantially large quantity of water. The bag configuration as shown in Figure 4A, as will be appreciated, has a large open end 27, substantially vertical section 28; and enlarged pouch 26, and an upper smaller exit aperture 29 which is closed by a draw string 30.
The activating mechanism 15 also serves as a means 2163~69 for holding and suspending the bag 16, the draw string 30 of bag 16 extending through two holes 31 in elbow 14 to be attached at a location 32 adjacent end 33 of mechanism 15.
Mechanism 15 has two arms 34 adapted to extend around the upper end of elbow 13 to be pivotally attached thereto at 35.
The front face 36 of mechanism 15 has a vertically extending tongue member 37 which is substantially curved outwardly, away from elbow 14. The mechanism 15 has a first horizontal section 38; intermediate vertical section 39; and a final horizontal section 40, adjacent end 33 of mechanism 15. Located to extend through vertical section 39, is an adjusting screw 41. As can be seen from Figure 4, the draw string 30 of bag 16 passes through holes 31 in elbow 14 through hole 32 in section 40 of the activating mechanism, where it is knotted and fixed in place. The adjusting screw 41 is provided with a rubber knob 42 at its inner end and the purpose of this screw is to temporarily locate the discharge pipe 19 in place when in the upper stored position (Figure 1). The rubber knob 42, coming into frictional contact with the inner surface of discharge pipe 19 (see Figure 1).
The operation of the inventive structure once assembled is relatively simple. Commencing in the upright, stored position (Figure 1), with the 216346~
adjusting/holding screw 41 maintaining the discharge pipe 19 in the upright position and the curved end of tongue member 37 bearing against the outer surface of the discharge pipe extension 19, water, entering bag 16 via the down-pipe 11 starts to fill the bag, in particular, the enlarged pouch section 26. As the weight of the water increases in the bag, the draw string arrangement around the exit aperture 29 of bag 16 tightens and exerts a force on end 33 of mechanism 15, which, under that force pivots about 35. Tongue member 37 pushes against discharge pipe extension 19 forcing it away in the direction of arrow "C"
(Figure 1). Once extension 19 has been pivoted past its point of balance, it continues to pivot under gravity to its fully extended position tFigure 2).
The water in the bag, by virtue of the continued flow from the down-pipe 11 will then open the exit aperture 29 of bag 16, thus allowing water to pass freely through the system.
To control the lowering or dropping of the extension discharge pipe, and to avoid consequential damage, it is necessary to provide some form of braking system. As shown in Figures 1 and 2, one method is to provide a counterweight 43, suspended by a nylon string 44, which passes through an eyelet 45 attached to the down-pipe 11 to a connecting point 46 on the discharge pipe extension _ g _ 2l6~q69 19. The counterweight 43 which can comprises either a solid weight, or a bag filled with lead or steel shot, therefore allows for controlling downward fall of the pipe from the stored position to the in-use position.
When it becomes necessary to reset the apparatus, the extension pipe 19 is manually moved back into the stored position (Figure 1), to be once again held in place by the adjustment screw assembly 41. Excess water still held within the bag 16 can be squeezed out. The apparatus is then in a condition for future use.
It will therefore be appreciated that while apparatus has been disclosed that is relatively simple in structure, installation and operation, various modifications can be readily made without departing from the overall scope of the appended claims. For example, the same structure can be utilized with down-pipes of cross-section other than square, and the counterweight system can be replaced with an elastic member, located in the same essential position as the arrangement shown.
In addition, while the elbow 13 is disclosed as having an apertured underside, to permit location of the bag, it will be appreciated that the bag could, without departing from the scope of the invention as described herein, be attached to the mouth of the elbow to hang externally thereof, the aperture in the elbow being 2163~69 omitted. The operation of the assembly would not, with this modification be altered.

With reference to the drawings, the down-pipe extension assembly, generally indicated at 10, is mounted at the lower end of a conventional down-pipe or spout 11, which is conventionally attached to the outside wall 12 of a building.
The extension assembly 10 comprises a discharge spout coupler 13; an elbow 14; an activating mechanism 15 which includes a water bag 16 (see Figure 4 and 4A). The discharge spout coupler 13, (Figure 3), is a elongate channel member, rectangular in cross-section, having a bottom 17i sides 18 and an open top. The sides 18 towards outer end 18A of the coupler 13 are reduced in vertical 2163~69 height to allow insertion into a discharge pipe extension 19 (shown in phantom outline).
