PERCH FOR A LADDER Filed Sept. 5, 1964 INVENTOR RUDOLPH J. KWIATKOWSKI fl/ United States Patent O "ice 3,294,197 PERCH FOR A LADDER Rudolph J. Kwiatkowski, 816 W. 3rd St., A Erie, Pa. 16507 I Filed Sept. 3,1964, Ser. No. 394,118 2 Claims. (Cl. 182-120)l This invention relates to new and useful improvements in ladder attachments and, more particularly, to a portable safety ladder perch which may be attached on a conventional ladder. Conventional ladders do not provide a satisfactory foot support, especially where prolonged standing is required on a single rung. Perches which were previously provided have had various disadvantages.
Accordingly, it is an object of this invention to provide an improved platform which is easily mounted on a ladder rung and provides a flat foot supporting surface and is simple in construction, economical to manufacture, and simple and efficient to use.
Another object of the invention is to provide a safety perch which will not be released when jarred or pushed out of position. The user must release the perch when it is to be removed.
Another object of the invention is to provide an improved safety perch, which may be adapted to different sizes and kinds of ladders.
Another object of the invention is to provide a more substantial perch so that the more pressure exerted on the platform when in use, the more pressure on the side rails of the ladder, whereby it remains in position during working conditions.
Another object of the invention is to provide a safety perch which is durable when put to use.
Further objects, features and advantages of this invention will become apparent from a consideration of the following description when taken in connection with the accompanying drawing in which:
FIG. 1 is a perspective view of the invention in use;
FIG. 2 is a perspective view of the invention;
FIG. 3 is a cross sectional view taken on line 3-3 of FIG. 2; and
FIG. 4 is a perspective view of the safety catch mechanism of the invention.
Now with more particular reference to the drawing, FIG. 1 shows a man standing on the platform 11 of the perch. The perch has hooks 14 which are hooked over the rung 31 of ladder 30. The lateral support bar 15 may be made to a length suitable for accommodating different size ladders. The support bar 15 will rest against the side rails 32 of ladder 30.
The Safety perch platform 11 may be made of steel plate of to 3/32" thick or some other similar material. The unit may be stamped out of metal plate in one piece -with two holes 17 and two slots 18 and then pressed over a die to bend the arms 12 at right angles to the platform 11. The top surface 11 will be rectangular in shape with a pair of downwardly extending triangular shaped arms 12. The bottom part of these arms will contain an opening 17 of the size to accommodate or 1/2" pipe approximately two feet long. After it has been placed in the opening, the pipe will be welded at 29, thus giving additional support to the extending arms 12. The top surface will also have a flange 13 extending downwardly which will be welded at 28 where the flange 28 meets with the extending arms 12. The purpose of this fiange 13 is to give additional strength to the top platform 11.
The hooks 14 which extend from the top platform will be bent downwardly and will extend generally parallel to the adjacent edge of arm 12. The distal end of hook 14 has a slot 18 therein. The end of the 3294,19 7 PatentedDec. 27, 1966 hook is curled upwardly to form an eye and receive the pin 24. The catch 20 has an upper edge that is curved to conform to the rung of a ladder. The back part of the catch 20 will have an L-shaped leg 21 which will rest against the back part of the hook when the catch is in position in slot 18. A fixed spring 19 will be attached by screw 22 to the base of the hook and will overlap the lever 25 of catch 20 to hold it under tension.
The catch 20 has an arcuate lower side which will conveniently slide over the ladder rung on a ladder during installation of the perch. The upper side of the catch 20 is convex so that it will underlie the ladder rung and conform generally to the surface of the ladder rung and will therefore prevent the perch from being removed. The rear side of the catch 20 has the laterally extending lever 25 which overlies the back surface of the hook 14 and is supported between the spring 19 and the back surface of the hook 14 and also functions as a handle to move the catch 20.
The leg 21 moves through the lateral portion 26 of the slot 18 when a ladder rung is moved into the space between the arm 12 and the hook 14. The catch 20 is hinged to the pin 24 loosely so that the catch 20 can be moved laterally and the end moved to overlie the back surface of the hook 14 when the perch is being installed or removed from the ladder so the catch will not interfere.
The slot 18 will have an L-shaped notch in the uppermost part so that when the catch 20 is pushed back out of the locking position the end 21 of the catch will hold the catch for removal from the rung of the ladder.
The hooks may be provided with a stiffening rib 16 and also the top of the platform near the hooks may have a rib 33.
The top surface of the platform may be coated with a non-slip material of the grit type to prevent slipping.
This perch is designed so that the person using it may carry it in one hand and place it in position on the ladder With one hand. At it is pushed in, the catch automatically locks itself on the ladder rung and the pipe will rest against the side rails of the ladder thereby giving a level platform for the Worker to stand on.
Although the invention has been described with respect to a preferred embodiment thereof, it is to be understood that it is not to be so limited, since changes may be made therein which are within the scope of the invention as defined by the appended claims.
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. A perch for use on a ladder comprising a platform,
arms attached to said platform and extending therefrom generally at right angles thereto,
a bar,
said bar being fixed to the distal end of said arms,
the ends of said bar extendin'g outwardly a substantial distance beyond the outer sides of said arms and adapted to overlie the side rails of a ladder,
hooks,
said hooks being attached to said platform at spaced positions thereon,
said hooks having a surface adjacent said arms generally parallel thereto and spaced therefrom and adapted to receive a ladder rung therebet'ween,
a catch swingably attached to said hooks to the distal ends thereof and adapted to swing under said rung to hold said hooks against movement from said |ladder,
said platform and arms being made of sheet like material with said arms integrally attached to said platform,
a -portion of said platform being bent downwardly to a position at right angles to said platform,tforming a reinforce-ment to said platform,
said catch having a laterally extending lever thereon which overlies the rear surfaces of said hooks, w
and a spring ai'fixed to said hooks which engages said lever, urging said catch to a position to overlie a ladder rung.
2. The perch recited in claim 1 wherein said hooks each have a slot therein and said catch i swingably supported on said hook and disposed 'in said slots,
said hooks each have a laterally extending leg theresaid slots have a laterally extending portion through which said legs may move said catch being movable laterally 'on said hook, whereby said laterally extending leg may Aoverlie said hook when said catch is moved laterally, whereby said catch will be held in a position remote fr'bm said arm of said pe'rch.
