B. E. WEIRICK HAND SLED Filed May 29, 1946.
Patented Oct. 17, .1950 7 UNITED HAND SLED Burnell E. Weirick, Kalamazoo, Mich, assignor to Kalamazoo Sled Company, Kalamazoo, Mich, a corporation of Michigan Application May29, 1946, Serial No. 673,099
1 Claim. 1
The main objects of this invention are:
First, to provide a hand sled. having knees which may be formed of relatively light sheet metal stock and at the same time are very rigid and capable of withstanding severe shocks and strains.
Second, to'pro'vide in a hand sled an improved knee structure which is graceful and attractive in appearance and at the same time strong and rigid.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined in the claim.
A structure which embodies the features of the invention is clearly illustrated in the accompanying drawing, in which:
Fig. l is a side elevation of a hand sled embodying my invention.
Fig. 2 is an enlarged fragmentary view in transverse section on line 22 of Fig. 1. I
Fig. 3 is a fragmentary, plan view of one of the knees and a runner, the knee being partially in section on line 3-3 of Fig.2. 7
Fig. 4 is a perspective view of the parts constituting a knee before the assembly of the parts.
The embodiment of the invention illustrated is a coasting sled of the steerable runner type, that is, the sled is steered by the flexing of the front ends of the runners, A sled of this type is illustrated in the patent to- Kidder No. 2 ,243,- 345, issued May 27, 1941, but as these flexible runner steering features are known in the art and constitute no part of the present invention, they are not illustrated in detail herein.
In the embodiment of my invention illustrated are outwardly curved. The legs and their flanges merge into the top brackets I.
To further stiffen and reinforce the legs I provide the generally triangular reinforcing plates 2! which are curved to correspond to the curved edges 20 of the flanges l1 and have inwardly projecting flanges 22 on their vertical edges which are disposed in overlapping closely embracing relation to the flanges I1 and welded thereto as indicated at 23. The lower corners of the plates 21 extend to a point adjacent to the runner. The bracket portion] is provided with a projecting outer end portion 24 which overhangs the. upper edge 25 of the reinforcing plate. The
reinforcing plates are adapted to receive some emblem or indicia 26, the letter K being shown in the drawing. a
This arrangement of parts permits the use of relatively light stock in the forming of the knees which is of advantage both from the standpoint of forming and in the cost of material, and also the generalweight of the sled.
I have illustrated and described the invention in a highly practical embodiment thereof. I have not attempted to illustrate various modifications and adaptations contemplated as it is believed this disclosure will enable the embodiment of the invention as maybe desired.
Having thus described my invention what I c aim as newand desire to secure by Letters f Patent is:
the raves l of the top board 2 are secured upon the cross bars or benches 3. The runners 4 are of T cross section, the upwardly projecting web 5 providing means for attachment of the legs of the knees thereto. The knees, designated generally by the numeral 6, comprise the top or attaching brackets 1 having the downwardly diverging legs 8 formed integrally therewith as sheet metal stampings. The: top or bracket portions 1 have bosses 9 and ID, the bosses 9 being provided with holes I! adapted to receive the bolts 12 shown by dott d lines in Fig. 2, while the bosses II) have slots 13 adapted to receive the bolts l4 shown by dotted lines in Fig. 2. This permits the legs to pivot on the bolts 12 and to flanges l8, the innerflanges being of increasing width from bottom to top and having'out-turned reinforcing edge portions I9. In the embodiment illustrated the outer edges 20-of the flanges ll oscillate on the bolts M which facilitates the steering or the flexing of the runners.
A knee for a hand sled comprising a top attaching portion and downwardly diverging'legs integral therewith and of downwardly facing channel section of increasing depth from top 'to bottom thereof and bifurcated for attachment to a runner, the legs having outwardly projecting flanges alongtheir outer edges, said flanges diverging downwardly along their length with said legs and converging slightly outwardly and downwardly laterally along their width, the edges of the flanges being laterally outwardly curved, and a triangular reinforcing plate conforming to said leg flanges and having. inturned edge flanges closely embracing and welded thereto, the outer end of said top portion being in overhanging relation to the upper edge of said reinforcing plate which is disposed withits upper end closely adjacent thereto.
