The present invention is concerned with a splash block and more particularly a preformed one of metal. : It is conventional practice to provide some means, usually termed: a. "splash block," .to re-ceive the rain water :issuing from each down, spout of building gutters and to carry this water away from the foundation to a point where it will cause no injury. Such a splash block is conventionally made of: concrete and is molded -in the desired' position. The difficulty with this conventional type of splash-block is that the block not only requires considerable labor to make but does not stay in the desired position due to the settling of the ground.: Such splash blocks are usually laid just after the building is completed. and on soil which has only recently been "filled in" around the foundation. In many cases, the resultant settling causes the splash block to change in position so much as to deflect the water towards the building instead of away from it.
Furthermore, such blocks eventually often become cracked, necessitating their replacement.An object of the present invention is to provide a preformed splash block of metal which has means to enable the splash block to be easily secured to the ground....
A further object of the present invention is to provide such a splash block in which the stream of water diverges as it approaches the outlet of the splash block so that the issuing stream, is spread over a relatively wide area.
A further object of the invention is to pro-vide. a splash block in which the up-turned side walls bounding the fluid channel not only diverge from the inlet to the outlet but also decrease in -depth so as to be entirely non-existant at the outlet end of the splash block.
A further :object of the:. invention is to formi such a splash block of sheet' metal by either a bending or stamping operaion.. .
Further objects of the present invention 'will be_ apparent from consideration of the accompanying specification, claims,' and drawing, in which -": . .: Figure 1 is an isometric view of my splash block applied in position and secured to the ground underneath a rain down spout;; Figure 2 is a transverse sectional view of te the splash block taken along the line 2-2' 2of Figure. 1; : ' SFigure 3 is an isometric view, corresponding to that of Figure 1, of a modified form of splash block; and Figure 4 is a transverse sectional view of the splash block of Figure 3 taken along theI line 4-4..
'Referring to Figure 1,;the conduit portion of the splash block is generally indicated by the reference numeral 0. - This conduit portion is formed of sheet metal formed to provide a flat bottom wall I I. Along the sides:of bottom wall I1, the sheet metal is bent up, at an angle to form side walls 12 and 13. :It ill be noted that these side walls are bent along lines diverging from the center line as the outlet is approached. . Furthermore, each of the wall portions: 12 and 13 is in the form of a triangle so that the:width of the wall decreases towards the, outlet. .These triangular walls 12 and 13, it will be noted, do not extend all the way to the outlet but entirely disappear at points 14 and 15: spaced a-short distance from the outer end :.of the 'conduit I8.
The sheet metal beyond the' side wall portions 12 and 13 is bent downwardly to form depending flanges I1 and IT. These depending flanges are again of a triangle shape converging toward the outlet side.: Instead, however, .of disappearing entirely before the outlet end of the conduit is reached, these' flanges extend the full length of the conduit.. The inlet end of the conduit has aportion 18 bent up to form an inner end wall which is suitably secured to the side walls .12 and 13.
A plurality of stakes 21, 22, 23, and 24 formed of metal are secured to the conduit portion 0i of the splash block. As-best indicated in Figure 2 in connection with stakes, 23 and 24, the stakes are formed in pairs, each pair of stakes constituting the two legs of an inverted U-shaped member 20. Thus, stakes 21i and 22 form the-legs of one U-shaped member and stakes 23 and 24 the legs of a second U-shaped member. The horizontal prtion -2 of each U-shaped member 2: is secured by spot welding or any other suitable method to the underside of the bottom wall Ii -of the conduit portion 10. The flanges 16 and I 7 are also preferably secured in a suitable manner to the upper portion of legs 21 and 22 and legs 23 . and. 24 of the U-shaped members 26.: The U.shaped members 26 thus serve the dual purpose of providing pairs of stakes and also reinforcing the conduit portion of the splash block. As will be evident in Figure 1, the splash block is secured 'in the ground by forcing the stakes 21 to 24 inwardly until the bottoms of the triangular side flanges 1 6 and', ITengage the ground.
The splash block is placed in the ground at a " . position such that the inlet end is just back o the outlet of the down spout.: Referring to 0 the drawing,' the down spout is indicated by the ' reference numeral 30. The rain spout is suitably secured by any conventional means to the wall of a building 31. . It is to be noted that by reason of the trian"5 gular form of the side walls 12 and 13 and by reasonn of the fact that 'they are bent along a diagonal 'line, the side walls gradually: diverge towards the outlet to increase the width of the issuing stream. At the same time, they decrease 0 in depth and entirely disappear short of the outlet end so that the water is able to splash over the entire outlet end of the splash block. Thus, the water instead of all being directed onto one spot and creating an excessive amount of erosion of that one spot, is spread over a relatively wide area and is carried off without any damage to the surface on which it is directed.
It will be further seen that the process of installing the splash block is an extremely simple one. By reason of the relatively light weight of L the splash block, the splash block will not increase in any way the tendency of the ground to settle. If the ground does settle so as to change the angular position of the splash block undesirably, the splash block can be readily pulled out, of the ground and reinserted in such a manner that it properly directs the flow of water. It wilLbe noted that the splash block in: Figures 1 and. 2. can be formed by simple bending operations from standard sheet metal: stock. This enables the splash block to be formed readily in the factory under efficient production methods, thus decreasing the amount of labor which must be performed at the actual building site.
Species of Figures 3 and 4 25. In Figure:3.:I have shown a slightly modified form of splash, block. The splash block of Figure 3. is intended to be formed of lighter sheet metal, and to be formed by a die stamping op- 3 eration. 0 A conduit portion. 40' of this splash block comprises a base portion 41 which.is provided with a forward, edge 42'which may, if desired, be curved as:shown in the .drawing. Extending downwardly and forwardly from- this curved- forward edge 42; is a downturned lip portion 43; Struck upwardly from the base portion 41 is a continuous wall comprising side walls 45 and-46 and a curved end wall 48. The: depth of this wall is greatest along the curved end wall 48 and'-gradually diminishes towards the: outlet end of conduit portion 40 until the wall completely disappears short of the outlet end. Merging with this edge wall: and extending in an inclinedi plane. is- a top wall portion- 50 which similarly is of greatest width. t a point adjacent the: end wall 48 and gradually diminishes in width to a vanishing point as the eoutlet is approached. Extending' down from the top wall 50 is a flange 52. This flange extends continuously around the inlet end and. sides of the bottom wall' 41 and merges with the' lip' 43 at' the outlet end. As is evident from the drawing, the depth of this flange 52 is greatest at the curved inlet end and 5; gradually decreases towards the outlet end. .Th e purpose of this, as in connection with flanges 16 and IT of the species of Figures I and 2, is to insure that the bottom' 41 is suitably inclined when the side flange engages the ground. In CO order to facilitate the stamping operation, grooves 54 are formed in the curved portion, of the side flange 52.
In order to- increase the rigidity of the- slash block, a plurality of ribs 55 are formed, in, the 6 base.portion 41. These ribs act to stiffen the conduit and to generally, increase its rigidity.
Furthermore, they provide diverging channels to.help spread out the stream of water as it approaches the outlet. Similar ribs 60 may be provided, adjacent the outlet end of the base portion and extending parallel to the forward edge 42 of: the base 41.
As with the previously described species, a plurality of stakes 56, 57, 58, and 59 are secured to the conduit portion 40 of the splash block. As with the other species, stakes 56 and 57 on the one hand and stakes 58 and 59 on the other hand each constitute two legs of a U-shaped.member 61 the horizontal portion of which is secured to the under side of the base 41 of the conduit section 40. A side flange 52 is secured to the stakes 58 and 59 so as to increase the rigidity of the splash block.
The splash block of Figures 3 and 4 possesses the various advantages set out for that of Figures 1 and 2. In other words, it is light in weight and causes no settling of the ground. Furthermore, the position of the splash block can be readily changed at any time when such a change is desirable. All of the work of forming is done at the factory and the only work of installation necessary is that of forcing the stakes into the ground. The splash block not only conveys the water away from immediately beneath the down spout buf: causes the stream of water to be so' spread out sas to cause no damage to the surface which it engages.
While I have shown certain specific embodiments of my invention for purposes Of illustration, it: is to be understood that the inventionl is to be limited only by the scope of the appended claims.
