DETAILED DESCRIPTION

(15) Reference is now made to the drawings for one embodiment of the ladder footing apparatus of the present invention. A first embodiment is illustrated in FIGS. 1-11 and an alternate embodiment illustrated in FIG. 12. The alternate embodiment of FIG. 12 essentially provides a separate auxiliary rung or step for assisting in using the ladder. Also, FIGS. 7-11 illustrate the ladder footing apparatus of the present invention as engaged with a stabilizer piece.

(16) For the use of the apparatus of the present invention indoors, it is common to be able to have the ladder resting against one sidewall and having an opposite sidewall of some type for retaining the ladder footing apparatus of the present invention. In this regard, reference may be made to FIG. 6 showing the ladder footing apparatus 10 as engaged against a wall surface indicated at 62. If one was trying to stabilize the ladder for use outdoors, the sidewall 62 could be a section of stationary decking. Refer also to FIG. 8 that shows a sidewall at 62. Refer also to the side elevation of FIG. 11 wherein the ladder may be stabilized for outdoor use by means of the stabilizer piece 40 that can be engaged in a ground surface.

(17) The ladder footing apparatus is used for supporting the base of a ladder which is typically positioned against a first wall structure such as at 63 illustrated in FIG. 6. It is the top end 60A of the ladder 60 that is positioned at this first wall structure 63. The ladder 60 also has a bottom end 60B that is supported on the rest surface S. In this regard, refer to FIGS. 6 and 8. FIG. 6 illustrates the top end 60A of the ladder that rests on the first wall structure 63. FIG. 8 illustrates the bottom 60B of the ladder 60 supported on the rest surface S. The ladder footing apparatus of the present invention is comprised of an elongated handle that is basically in the form of a pole. This handle is illustrated at 12 in the drawings. Associated with the handle 12 is an adjustment member 13. The handle 12 is preferably adjustable to different lengths and in this regard may include a telescoping section. One end of the handle, as illustrated at 15 in FIG. 2A, is mated with the hook member 21. The other end of the handle 12, such as illustrated in FIG. 4, may be engaged with a post 38 having an internally threaded passageway at 37. The end of the handle 12 may be engaged with a coupling 34 open at 35 and threaded at 36 for engagement with the threaded aperture 37. The opening 35 engages against an end of the pole 12 and may be permanently affixed thereto. In this way, the handle 12 is adjustable in length and once adjusted to a desired length, is secured such as by means of the securing or adjustment member 13. The telescoping nature and the adjustment and securing of the handle may be by means well known to one skilled in the art.

(18) The ladder footing apparatus of the present invention also includes a resilient pad member 16 that is supported at one end of the elongated handle. The resilient pad member 16 is for engaging a second wall structure such as illustrated by way of example in FIG. 6 or FIG. 8 with the structure 62 representing a second wall structure. This second wall structure is usually arranged in opposed position to the first wall structure.

(19) The ladder footing apparatus of the present invention also includes a hook member 41 supported at the other opposed end of the elongated handle. This hook member is for engaging a lower rung of the ladder. In this regard, reference may be made to, for example, FIG. 6 showing the hook member 22 engaged with the rung 64 of the ladder 60. Refer also to FIGS. 7, 8 and 11 showing the manner in which the hook member engages with the rung of the ladder. This engagement is preferably with the lowermost rung of the ladder, although it may also be engaged with a rung above the lowermost rung.

(20) The resilient pad member comprises a rigid substrate 30. This may be in the form of a rectangular rigid plate member. The resilient pad member 16 also includes a resilient pad 32 that is fixedly mounted to the substrate 30. Between the end of the handle 12 and the resilient pad member there is provided a pivot. This enables the angle of the handle relative to the pad member to be secured at different angles dependent upon the distance between the ladder and the second wall structure. In this regard refer to FIGS. 3 and 4 illustrating the end of the handle having a pivot section 17 that carries a pivot pin 18. The pivot section 17 includes a forked piece F having two tines T. The pivot pin 18 passes through an aperture A in the rod 20. The rod 20 forms part of a pivot mechanism 19 that is secured to the backside of the rigid substrate plate 30.

(21) The hook member 21 such as illustrated in FIGS. 2 and 2A comprises an open hook 22 that is comprised of plural sidewalls 26 that are formed into an essentially U-shaped structure that is adapted to engage against a rung such as shown in FIGS. 7 and 8. In the embodiment that is described, such as in FIG. 2A, the U-shaped structure is formed by five sidewalls 26 including a center sidewall 26A that is attached with the handle. This also includes a pair of outer sidewalls that extend about the ring. In the embodiment of FIG. 2A there are actually two sidewalls 26 above and below the center sidewall 26A.

(22) Also, and as illustrated in FIG. 2, the hook 22 may be provided with an opening 27 formed between end pieces 28. This arrangement is helpful in locating the hook member about the rung as the opening 27 provides for a viewing of the rung relative to the hook member.

(23) As indicated previously, particularly for use outdoors, there may not be a convenient second wall structure and thus one of the important components of the present invention is the use of a stabilizer piece 40 such as illustrated in FIGS. 5 and 9-11. See in particular the side elevation view of FIG. 11 with the stabilizer piece 40 inserted into a ground surface 47 to essentially lock the stabilizer piece in place. By doing that the ladder footing apparatus has a fixed location and is thus essentially anchored at that location preventing the ladder from any movement.

(24) The stabilizer piece thus essentially forms a second walls structure. The stabilizer piece has opposed end flanges 42 that define an open slot 43 into which the resilient pad member may be slid. FIG. 9 illustrates the resilient pad member 16 positioned over the slot 43. In FIG. 9 arrows A indicate the manner in which the resilient pad member 16 may be slid into the slot 43. Refer also to FIG. 10 that shows the pad member 16 in place secured with the stabilizer piece.

(25) The stabilizer piece in addition to including the end flanges 42 also includes a top bar 44 that is formed integrally with a pair of downwardly depending legs 46 that are for engagement with the ground surface. The top bar 44 may be secured to the legs in any one of a number of different ways. As also illustrated in FIG. 9, there are preferably a pair of bottom lips 45 upon which the resilient pad member rests. One of these lips is shown in FIG. 9 and it would be another lip position similarly associated with the opposed position flange 42.

(26) Another aspect of the present invention is the use of a ladder footing apparatus kit. This kit is preferably comprised of:

(27) (A) a ladder footing apparatus that is comprised of an elongated handle having respective one and other opposed ends, a resilient pad member supported at the one end of the elongated handle, and a hook member supported at the other opposed end of the elongated handle; and

(28) (B) a stabilizer piece that is meant for planting in a ground surface and for support of the resilient pad member.

(29) Thus, one can provide a kit that is basically comprised of the ladder footing device as well as the stabilizer piece. In that way, one can use the ladder footing device without the stabilizer piece as long as there is access to a second wall structure. On the other hand, particularly for out of doors use, the stabilizing piece can be engaged with a ground surface for providing the stabilization that is necessary for the ladder footing device of the present invention.

(30) The perspective view of FIG. 12 shows an arrangement in which a different hook member is provided. This is comprised of a pair of hooks 74 that are engaged with a rung 64 that is not necessarily a bottom rung of the ladder. In this embodiment at the hook end of the device, there is provided a cross bar 70 attached at the end of the handle. A pair of side legs 72 assist in supporting the bar 70 from the handle. Around the middle of the bar 70 there are provided angled pieces 73 that extend to and support the respective hooks 74. One of the advantages of this embodiment is that the bar 70 can also function as an auxiliary rung or step while the apparatus is fixed in position. The auxiliary step 70 is disposed forward of the ladder structure.

(31) A similar step may also be provided in the embodiment illustrated in FIGS. 1-3. This is provided by means of the triangular base piece 24 that provides a sufficient surface area and that may be stepped upon to assist one in using the ladder. FIG. 8, for example, illustrates the triangular base piece at 24 which would provide a sufficient surface area for stepping on to the ladder to assist the user of the ladder.

(32) Having now described a limited number of embodiments of the present invention, it should now be apparent to those skilled in the art that numerous other embodiments and modifications thereof are contemplated as falling within the scope of the present invention, as defined by the appended claims.
