FIG.
United States Patent Office 3,148,892 Patented Sept. 15., 1964 3,148,892 CREEPER LOUNGER Clyde E. Merriott, 6102 22nd St., Lubbock, Tex. Filed June 17, 1963, Ser. No. 288,302 6 Claims. (Cl. 28.9-32.6)
This invention relates to improvements in the field of mechanics creepers and more particularly to creepers for aircraft and large auto truck use.
The hands, arms, and shoulders are generally accepted as the mechanics Tools in Trade. Accordingly, it is an object of this invention to make work more accessible to these Tools of Trade or put same in a better position to work.
A further object of this invention is to provide a strong, comfortable creeper from which to perform duties, hence the name creeper lounger. There have been other creepers built with a hinged backrest and several different positions. This invention, however, provides also a hinged seat that tilts automatically as the backrest is raised. This insures against the natural sliding motion of the body; that is it will hold the mechanic firmly in position.
Still another object is to provide nine different settings to hold a rnechanics shoulders in positions ranging from approximately six to twenty-six inches above the floor.
Another feature is the provision of a large headrest cushion which can be adjusted for the height of the mechanics body.
Still further objects are to achieve the above with a device that is sturdy, compact, durable, simple, versatile, and reliable, yet inexpensive and easy to manufacture and operate.
The specific nature of the invention as well as other objects, uses, and advantages thereof will clearly appear from the following description and from the accompanying drawing, the different views of which are not necessarily to the same scale, in which:
FIG. 1 is a perspective view of the creeper showing the backrest and seat members in the extended position.
FIG. 2 is a side view of creeper in full raised position.
FIG. 3 is a bottom view of seat-backrest assembly detached from the frame for clarity.
FIG. 4 is a perspective of the main frame embodying the seat adjustment serrations.
Frame 1 is built of one long piece of angle iron. The corners of the inside of the angle are cut to fit flush when bent to make a square corner, and are welded on the inside. The frame is rectangular in shape. The frame 1 forms a flat bottom surface. Attached to the frame are four conventional creeper casters 2, one on each corner being attached with four bolts and nuts 3.
Attached to the inside of the frame on one end along each side will be two serrated or notched angle iron metal pieces 4, hereafter called notched adjustment having eight notches which extend upward from the lower portion of the frame, each attached by one bolt and nut 3 of the aforementioned casters 2, and one bolt and nut 5 attaching the other end. These notched adjustment pieces 4 extend from approximately two to seventeen inches from one end.
Attached to the inside edge of the frame and on the opposite end from the notched adjustment are two rollers 6, one on each side, each being attached with one bolt and nut 7 in like positioned holes in frame 1, the holes being drilled so as to'position the upper side of each roller 6 level with the top of frame 1. The three holes on each side are one-half inch apart for adjustment and are positioned in line.
One hole is drilled in each side of the frame 1 for attaching seat-backrest assembly 8, FIG. 3, approximately six inches toward the center of frame 1 from the center hole for roller bolt 7 and five-eighths inch from the bottom edge of the frame.
The seat-backrest assembly 8, FIG. 3, is constructed with five plywood panels with side rails of hardwood. The seat 9 will have a piano hinge 24 attached to the rear upper edge with a light piece of metal on the bottom of the seat forming backing strip 13 with bolts and nuts 20.
Hardwood rails 11 are cut with an approximate 45 degree angle on each inside end. The other ends are cut perpendicular and the corners and upper edges are rounded so as not to leave sharp corners for the mechanic to bump against. They are attached on the top of each side of the seat 9. Wear strips 14 made of light metal are underneath the seat 9. Bolts and nuts 19 extend through each end of rails 11, seat 9, and wear strips 14.
On the extreme top end of backrest 1% is mounted large plastic or leather covered cushioned headrest 23 which is attached with two screws passing through from underneath the backrest in either of three pairs of holes 25 in the backrest.
The bolts 21 are the only attaching points for seatbackrest assembly 8 to the frame 11). They act as pivot points. The rollers 6 are pivots for the seat 9., The metal leveling strips 15 rest on the frame .1 in full ex tended position. The piano hinge 24 is the pivot point between the seat 9 and backrest 10.
When the backrest 10 is raised, the hinge'24 tilts down, dropping the rear part of the seat 9. The seat 9 in turn riding on rollers 6 which are stationary in any of three positions, will force the seat 9 up in front. A mechanic t sitting on seat-backrest assembly 3 will not have any sliding tendencies.
The aforementioned three positions of the rollers 6 are obtained by removing the attaching bolts of said rollers and reinstalling them in another pair of matched holes in the frame 1. This adjustment will govern the degree of tilt of the seat 9 in relation to the backrest 10.
It will be. noted that the frame 1 is over of the combined length of the seat 9 and backrest 10. This is so that when the backrest is elevated as seen in FIG. 2, that the creeper as a whole will be stable. It will be understood that as a mechanic works that he will exert leverage pressure, thus he will be using the backrest 10 as a platform to exert pressure against the material he is working upon, so therefore it is necessary that he have as large a frame 1 as possible with which to work. I
