According to an aspect of the invention, the eavestrough includes a downwardly directed lip forming one part of the locking arrangement on each locking flange which are used to assist in locking of the eavestrough in a suitable eavestrough hanger.
According to a further aspect of the invention, the flange and the associated vertical section cooperate to provide an 'L' shaped ledge about the flange. This 'L' shaped flange is used to provide an abutment like support for receiving an eavestrough accessory or one edge of an eavestrough accessory, such as a leaf guard.
According to yet a further aspect of the invention, the eavestrough is fully symmetrical eikher side of the base and can be installed in either orientation.
An eavestrough hanger, according to the present invention, comprises a cored base and a forwardly extending cantilevered arm extending from the base. The arm is of an inverted 'T' shape in cross section and includes a front opening locking slot at a free end of the arm. An opposite 2û opening slot is provided at the lower edge of the arm spaced from, but adjacent the base. The base and the arm join at a flange perpendicular to the inverted 'T' shaped section and generally centered thereon. This flange closes the inverted 'T' section at one end of the arm and is used to assist in securing of the arm to the base.
According to an aspect of the invention, the hanger includes a rectangular extension joining the flange and the base.
According to a further aspect of the invention, the 3û eavestrough hanger is adapted with the base extending above the inverted 'T' shaped section and including in this extension portion a securing port therein for fastening of the hanger.
According to a further aspect of the invention, the eavestrough hanger is adapted by including a forwardly ~ 3 ~ 7 WH-7408-88 . 3 . 1465H/0062F
opening slot in the base, across the base intermediate the inverted 'T' shaped section and the securing port.
BRIEF DESCRIPTION OF THE DRAWINGS
Preferred embodiments of the inven-tion are shown in the drawings, wherein:
Figure 1 is a partial perspective view showing one hanger and a portion of a building to which the hanger and eavestrough have been secured;
Figure 2 is a partial perspective view illustrating how the eavestrough section can slide within a hanger; and Figure 3 is a side view showing the securement of the eavestrough section in the eavestrough hanger.
DETAILED DESCRIPTION OF THE PREFERRED EMBûDI~ENTS
The eavestrough section 2 is preferably of a symmetrical section having agéneral1y flat base 4 and outwardly angled walls 6, each of which termina-te in a short vertical section 8. The vertical sections 8 each include a locking flange 10 having a downwardly directed lip 12 at the free end of the locking flange. This downwardly directed lip will cooperate with the locking slots provided in the eavestrough hanger. Above the upper surface of each locking flange 10 and the inside wall of the associated vertical section 8, is an 'L' shaped ledge 14. This ledge can be used for restraining one side of a ]eaf guard while also serving to further hide the hook.
The eavestrough hanger 30 has a cored base 32 which is essentially a rectangular box with certain interior partitions and open at the sides. The hanger 30 includes a forwardly extending cantilevered arm 34 of an inverted 'T' shaped section. This arm 34 at the free end thereof ?
includes a front opening slot 36 for receiving one of the locking flanges 10 by means of which the eavestrough is partially hung below the eavestrough hanger 30. Front opening slot 36 includes an angled camming surface 56 and a ~ 3 ~ 7 ~H-7408-88 . 4 ~ 1465H/0062F
lip 58 sized to provide an interference fit with the locking flange 10 and the downwardly dlrected lip 12. This type of interference fit is shown in Figure 3 and the eavestrough section may be forced as indicated by arrow 60 into the front opening slot 36. There is a similar jam type fit provided at the opposite opening slot 38 provided at the lower edge of the arm 34, but spaced from the base 32.
Again, the eavestrough is forced through a slot, in this case through slot 389 such that the vertical section extends into the upwardly extending portion 50 of slot 38, which is eventually limited by the rectangular section 42 with the appropriate locking flange located in the horizontal extending portion 52 of slot 38. This horizontal extending portion 52 includes a lip 54 at the entrance thereof to provide a lock with the cooperating lip 12 of the locking flange 10. These parts cooperate to provide a two-part interference locking arrangement.
The front opening locking slot 36 and the opposite opening slot 38 are sized to allow free movement of the eavestrough section within the slots to accommodate longitudinal expansion of the eavestrough section, however, the eavestrough is firmly locked within each slot due to the cooperation of the locking flanges 10 and slots 36 and 38.
The cored base 32 extends above the cantilevered arm 34 and defines in an upper region a securing port 44 through which a screw may be inserted to effect securement of the eavestrough hanger. The hanger also includes alignment recesses 60 provided at the rear surface of the base which are used in properly placing the eavestrough hanger the required distance below the eave of the roof.
For example, a line could be drawn on the fascia board, with this line appropriately sloped according to the requirements, and then the eavestrough hangers are located on the fascia board with the aid of alignment recesses 60 being placed on that line. In this way, each of the hangers ~ 3 ~ 7 WH-7408-88 . 5 . 1465H/0062F
will ensure that the eavestrough is properly sloped -to drain in a predetermined manner.
Both the eavestrough 2 and the eavestrough hanger 30 are made of a suitable ultraviolet stabilized plastic material, as is known in the art.
The particular eavestrough hanger 30, and the manner of coring the same, ensures there are minimal problems due to shrinkage of material during cooling of the hanger after the injection molciing thereof. The various cavities are interconnected by partitions to add structural integrity and each of the cavities terminate generally at a vertical plane through the base, centered on the base, such that there is a solid core of plastic extending from the rear of the base into the forwardly extending arm and therebelow. This vertical reinforcing adjacent the arm increases the strength of the hanger. The forwardly extending cantilevered arm 34 terminates at the flange 40 which is generally perpendicular to the 'Tl shaped section of arm 34. This flange is the same size as the base and stiffens the arm and provides effective load transfer between the arm 34 and the forwardly extending rectangular section 42. This forwardly extending section 42 is cored, however, rather than being vertically cored, it is cored in a generally horizontal manner to increase the structural strength thereof.
The cored base 32 of the eavestrough hanger 30 has a lower elongate box-like section 32a with a number of reinforcing partitions 33 extending therethrough. This elongate box-like section increases the stiffness of this lower base portion and thus stiffens the relationship between the lower portion of the forwardly extending arm and the base. The cored box-like area 35 provided above the forwardly extending rectangular section 42 a].so provides additional stiffening and this stiffening is reinforced by the bushing about the securing port 44. By coring of the base to provide a backwall and a forward wall, ~31~
WH-7408-88 . 6 . 1465H/0062F
interconnec-ted by a central partition running generally vertically and various horizontal partititions, less material is required and the configuration provides additional strength.
In molding of hangers of this type, there is difficulty in just adding more material, as after molding, shrinkage can cause distortion and flaws in the hanger.
Thus, by coring the hanger in the manner described and configuring it, the benefits in reduction of material are lû achieved while still providing a rigid configuration. Also, the molding of this article allows various configurations to be used, for example, the forwardly extending section 42 is perpendicular to the cored lower elongate box-like section 32a while the material is integral as the product has been mo]ded. This overlapping relationship of the various cored areas results in a strong base portion which also allows effective connection of the forwardly extending cantilevered arm 34 with the base.
When load is applied to the hanger by the eavestrough, it is opposed by the screw which is passed through securing port 44 and it is also opposed by the lower elongate box-like section 32a which will contact the facia and distribute the load thereto. As can be appreciated, the hanger or the forces on the hanger will tend to be downwardly directed causing a moment generally about the facia board and this is partially opposed by the reaction force acting on lower elongate box-like section 32a.
Therefore, this section must be stiff but also the connection of this section to the upper cored area 35 must also be stiff. Similarly, it is important that the - connection of the arm to the base is as stiff as possible to avoid flexing of the structure.
The strength of the arm is further improved by the flange 40 which is in a stepped wall configuration to partially define a locking slot while also connecting the lower flange o-f the forwardly extending cantilevered arm 34.
'7 WH-7408-88 . 7 . 1465H/0062F
In effect, the base is of a cellular type structure which not only allows convenient molding thereof, but also positions the material of the base in a configuration to improve the structural integrity of the base while allowing effective connection of the forwardly extending cantilevered arm to the base by means of the forwardly extending rectangular bridge section 42. Thus, the present design recognizes the need to not only limit the material used in the hanger, but to position this material in a manner to avoid problems often caused by shrinkage during cooling of the product after molding while effectively posltioning the material to improve the strength of the resulting structure.
The eavestroughing system, according to the present invention, uses a force fit of the eavestrough section into the hanger, avoiding problems which can occur when spring deformation is associated with the locking. Plastic typically creeps during heat and a spring bias type arrangement for locking does not provide the same structural strength as a locking interfit, where problems associated with creep are reduced. Furthermore~ this positive locking of the eavestrough within the eavestrough hanger avoids problems which can occur due to improper loading such as by placing a ladder on the eavestrough section. Such a load would tend to increase the securement of the locking flange within the forwardly opening slot 36 while the slot provides some support against buckling. The vertical section of the wall also strikes the end of the arm and further distributes the load.
An eavestrough under normal operating conditions is not subject to particularly high loads, however, it is subject to extreme temperature ranges from the coldest day in winter to the hottest day in summer and is also subject to ice loads and must at least withstand these loads which can greatly exceed the actual volume of the eavestrough.
Although various preferred embodiments of the present invention have been described herein in detail, it :
WH-7408-88 . 8 . 1465H/0062F
will be appreciated by those skilled in the art, that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.
