March 10, 1970 L A. FRO EDGE BA SECONNECTION FOR A PEDESTAL Filed April 5. 1967 INVENTOR- B LA/vis A- Ema-pas 27s Am United States Patent 3,499,625 BASE CONNECTION FOR A PEDESTAL Lanis A. Froedge, Chicago, Ill., assignor to Kaydee Metal Products Corp., Chicago, Ill., a corporation of Illinois Filed Apr. 3, 1967, Ser. No. 627,847 Int. Cl. A47b 91/00 US. Cl. 248188.7 2 Claims ABSTRACT OF THE DISCLOSURE SUMMARY OF INVENTION An object of this invention is to provide a pedestal with legs radially disposed about the lower end of the pedestal and extending laterally therefrom. The legs being rigidly supported by a Wedging pin positioned between the mating ends of the legs to reinforce and maintain the legs in proper radial position with respect to the standard during the welding operation of connecting the legs to the standard and to the welding pin.

The invention will be best understood with reference to the accompanying drawings showing the preferred form of construction and in which:

FIG. 1 is a fragmentary perspective view of the invention;

FIG. 2 is a bottom plan view of the invention taken substantially on line 2-2 of FIG. 3; and

FIG. 3 is a fragmentary sectional detailed view taken substantially on line 3-3 of FIG. 1.

The preferred form of construction of my invention is shown in the accompanying drawings in which the standard of the pedestal is shown at 10. The lower end portion 11 of the standard is provided with elongated longitudinally extending slots 12 located radially about the lower end portion 11 of the standard 10.

In the drawings, the pedestal base preferably comprises four legs 13, each of which is substantially of the same construction. The inner end portion of each of the legs 13 provides a head 14. The head 14 has at one end a lateral extension 15 which provides a shoulder 16 adapted to engage the inner wall of the standard 10. The upper portion of the head 14 is formed to provide a curved surface 17, which terminates at one end into a second shoulder 18, which extends in an opposite direction with respect to shoulder 16, and which engages the opposite or outer surface of the standard 10. The width of each head 14 is greater than the length of the slot 12. In assembling the legs 13 onto the standard 10, the extension 16 is first projected through the slot 12, which is of a length less than the overall width of the head 14, until the shoulder 16 lies geneath the lower edge of such slot, at which time the free end of the leg is raised so that the curved surface 17 of the head passes through the slot 12 until the second shoulder 18 engages the wall defining the upper end of the slot and the outer wall surface of the standard 10. After each of the legs 13 is so inserted into its respective slot 12, the point of contact of the shoulder 16 with the inner wall of the standard 10 may be fixedly connected by means of a weld, or the like. The shoulders receive the weight imposed upon the standard.

As shown in the drawings, when the legs 13 have each been positioned in their respective slots 12, they present within the standard 10 a socket 19 defined by the spaced 3,499,625 Patented Mar. 10, 1970 apart parallelly extending vertical edges of each of the heads 14. This socket 19 will receive a Wedging pin 20, which is of a size to be forcibly inserted into the socket 19 so as to wedge the shoulders 16 and 18 into clamping contact with the opposite wall surfaces of the standard 10 so as to connect each of the legs thereto.

The Wedging pin 20, as well as the shoulder 16, may be secured together by welding as at 21, to be fixedly assembled into a base structure.

Weight disposed upon the standard 10 will result in the Wedging of the heads 14 against the Wedging pin 20, thereby to provide a substantial rigid structure between the standard 10 and the legs 13 and to reinforce the welding 21 between the heads 14 and the Wedging pin and the side surfaces of the standard 10.

By this construction a substantial rigid connection results between the legs and the standard, a construction which is simple and easy of assembly.

The outer end portions 22 of the legs 13 are provided with suitable sleeves 23, to which may be connected the stems of suitable caster rollers (not shown). The foregoing structure is simple and economical in manufacture.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

1. A pedestal including an elongated vertically disposed hollow standard supported by a plurality of radially extending equidistant legs with the standard having formed therein adjacent one end a plurality of longitudinally extending slots each adapted to receive an end portion of a radially extending leg wherein the improvement comprises:

(a) a connecting head provided at one end of each of the legs,

(b) said connecting head including at one side thereof a lateral extension which together with said head has a greater overall width than the length of its corresponding slot,

(0) a shoulder formed between said lateral extension and said leg for abutting the inner 'wall surface of said standard adjacent one end of the slot after said head and said extension has been angularly inserted through the slot and said leg moved in one direction into a radially extending portion with respect to the standard,

(d) a second shoulder provided on the opposite side edge of said head and extending in a direction opposite to said first shoulder so as to abut the outer wall surface of said standard adjacent the opposite end of the slot to cooperate with said first shoulder to resist angular movement of said leg in one direction relative to said standard, and

(e) a Wedging pin positioned between confronting ends of said heads of each of said legs positioned within said hollow standard to bear against said heads to hold said shoulders against said inner and outer wall surfaces of said standard adjacent the opposite ends of said slots to prevent radial and angular movement of the legs relative to said standard so as to prevent withdrawal of said connecting heads out of said slots.

2. A pedestal as defined by claim 1 and further characterized by having each head of each leg formed to provide confronting elongated parallel ends positionable within said hollow standard and with said pin being of a length equal to the length of said confronting edges so 1,186,668 6/1965 Story 211--148 as to be in facial contact therewith throughout the full 3,186,669 6/1965 Buhrmaster 248-188] width of said heads to prevent any movement thereof 3,236,485 2/1966 Staples 248188.7 relative to each other and to saidstandard. 3,244,128 4/ 1966 Rogalski et a1 248188.7 5 3,325,017 6/1967 Tucker 211-148 References Cited a. v UNITED STATES PATENTS FRANCIS K.
