REENFORCED CONCRETE ARTICLE Filed March 11, 1929 Patented Mar. 29, 1932 UNITED? STATES AUGUSTE HENRI LEFEVREOF nurnfsua orsn rnitnvvnas, FRANCE BEENFORGED CONCRETE ARTICLE Application filed March 11, 1929, Serial No. 346,0 9 0, and in France March 20, 1828.
This invention relatesto knock down structures formed from pre-cast reenforced concrete members, of the type having suitably shaped recesses in some members to be detachably engaged by corresponding projections on other members.
According to the present invention structures generally of the type to which the invention relates and particularly garden or bed 1 frames formed as structures of this type comprise a plurality of cast reenforced concrete frame members having an L. shaped recess cast at each endthereof and a plurality of cross frame members having an L shaped lug cast on each extremity thereof, each lug being adapted to fit into one of the L shaped recesses. I
In a preferred construction the frame members having the recesses, are formed at each end with supporting posts and the, recesses are formed in the posts.
In order that the invention may be better understood itwill now be described with reference to the accompanying drawings in which Fi 1 shows a plan view of a demountable bed rame; I r
Fig. 2 is a lateral elevational v ew thereof; Fig. 3 is a front elevational v1ew thereof; 3 Fig. 4 is a perspective view of the frame and r Fig. 5 is an assembly detail in perspective.
Referring to the drawings, the frame comprises members 1 and 2, and members 3 and 4 assembled together at the interconnecting angles A, B, G, D.
The members extremities with recesses of L shaped section 5 in which fit projections 6 atthe ends of the members 3 and 4, forming with port ons of the members 3 and 4 Lshaped pro ect ons.
7 are supporting postsor feet in which the recesses 5 are formed in such a manner that the lower part of the projections bears upon the bottom of the recesses.
The shape of the recesses and the parts engaging therewith, in practice secures great rigidity, and in addition serves to assemble the parts in very correctangular relatlonship.
Moreover owing to the strength and nature 1 and 2 are formed at their oft-hehook engagement, although all the qualities required in the structure when assembled are present, yetthe taking apart is greatly facilitated. Further in the preferred form of construction, where the L shaped recesses are formed in the posts, owing to the increased section of the material comprised by the posts, more than adequate strength is given to therecessed parts. Again in the preferred construction as the recesses only extend from the top a portion of the distance down the posts, and the lower ends of the recesses terminate in stops, it will be realized that these stops form registering surfaces,
for limiting the insertion movement of the associated members. In this way the correct assembly (in the vertical sense) of the parts is facilitated.
Upstanding projections 8 (shown in Figs. 2 and 3) may be provided at the ends of the I members 1 and 2 to assist in the assembling of the frame and to maintainproper spacing.
It is to be understood that although the'invention has been particularly described in connection with a construction of a garden or bed frame, it may be applied to other suitable constructions such as various kinds of boxes,
cases and the like.
Having described my invention what I claim as new and desire to secure by Letters Patent is: r
A knock-down structure formed from precast reenforced concrete members of the type set forth, comprising two similar pre-cast reenforced concrete frame members each'of 85. desired thickness and of elongated rectangular form, rectangular section enlargements cast at each end of each of said frame members, the two enlargements on each frame member coming flush with one rectangular surface and projecting from the other rectangular surface, and each enlargement projecting for the same distance below the lower edge of the frame member and coming flush with the upper edge of the frame member, an L shaped recess cast in each of said enlargements and extending from the upper end down through a distance corresponding to the depth of the frame member and terminating-in a stop, the slots at each end ofthe frame member opening in the same direction, two similar pre-cast reenforced concrete cross frame members of desired thickness and elongated rectangular shape having a depth equal to the depth of the frame members, right-angled projecting portions at the two ends of each of the cross frame members, the two projections on a cross frame member both projecting in the same direction, each of the said projections constituting with the adjacent portion of its cross frame member an L section lug adapted to fit Within the L section recesses in the enlargements of the frame members, and to come to rest on the 1 stops formed at the lower ends of the recesses in the said enlargements, for the purposes 7 set forth.
' In testimony whereof I hereunto aifix my signature.
LEFEVRE, AUGUSTE HENRI.
