appncation mea `.nine so, 1925, serial No. 40,550.
This linvention presents a table of takedown, or knock-down, type particularly deability; (2) rigid union ofall of the ele-` ments which go to make up the table, when l the table is in assembled condition; (3) ease and rapidity with which the parts may be assembled anddisassembled; (4) absence of liability of any. ofthe elements from becoming lost or mislaid when .the parts have 2U been separated and arranged for storage purposes; and (5) provision. for the arrangement of the Vparts and their `maintenance in a most compact form for `storage and transportation purposes.
This invention, therefore, comprises certain novel combinations of parts correlated to answer the ,foregoing ,several requirements. More particularly expressed, the invention comprises: i
: i (A) A table whose top is composed of upper sections having their edges in a substantially abutting relation and lower members which cross the abutting edges of the loweri sections, together with legs `having shoulders below `their upper extremities and whose portions above said shroulders ex- -tend through the lower members and into the upper sections and are provided with fastening elements which engage therupper sections and are yadapted by relative rotative movemeiit of the shoulders and fastening element-s to act through the upper sections of the top to force the lower members ofthe4 top tightly upon the shoulders andtliereby unite all the parts into alrigid unitary structure; Y
(B) A table of take-down character comprising a top land legs, the top'having openings `and the legs having their upper rends provided with fastening elements which ,substantially form a. permanent part ofthelegs, sinceltliey are not detached in order to apply the legs to the top, or in removing the legs from the top, the legs having shoulders positioned below their upper ends, to beengaged by the underside of the top andthe portionsofthe legs above said shoulders, including` the fastening elements, being insertible into and removable from the openings in the top from theunderside of the top, and said fastening elements and legs being re1- atively adjustable by relative rotation thereof to set the fastening elements into holding relation With the top and to force the top and shoulders into a close engagement with each other;
(C) A table of takefdown character whose top is composed of upper sections and of lower members which cross the confronting edgesof the upper sections, and is provided with means for holding said sections and members in an assembled relation while the legs are being assembled with the top or are :being Separated from the top and which holding means are of such character as to permit the ready separation of the sections and removal ofthe members for storage purposes;
(D) table of take-down character having a top composed of separable upper sections and lower members and Valso having legs which are readily separable from the toptogether with fastening elements so correlated with the parts of the top and with the `legs that when the table is in an assembled condition, the top and legs will be rigidly united into alunitary structureand W en separatedmay belarranged in avery compact relation, the table also'comprising i means for holdingthe parts of the top in their stored relatlon and which means cooperates fwiththe lower members of the top to overcome any tendency of theupper members of the top to becomewarped, even when said upper members are made, as they should be for the sake of lightness of construction, oflthin material, which, therefore, isliighly susceptibleto a warping tendency, especially Whentlie table is subjected to ontsidey atmospheric. conditions.
The linvention further consists `in v certain details with relation to the construction of certain of its parts, calculated to carry out theobjects ofthe invention in a most advantageous manner. i
.In the accompanying drawings, wherein like characters of reference denote corresponding parts in the several views, I have illustrated an embodiment of the invention wherein the several `purposes of the invention are,` carried out by means of most simple land practicable nature, and while I shall Malawi lil) describe said embodiment in detail I would have it understood that the invention is not restricted in all respects thereto and that changes may be made in details and that features of the invention may be embodied in specifically different forms without departing from the spirit of the invention as defined by appended claims. In said drawmms:-
Fig. 1 is a perspective View of the table, assembled for use,
Fig. 2 isan enlarged fragmentary sectional view taken substantially on line 2 2 of Fig. 1 illustrating the detail construction of the leg fastening means and how the parts assembled for use are secured in position thereby,
Fig. 3 is an end view of the table with a portion broken away to illustrate the construction of additional securing means,
Fig. 4 is a plan view of the table as shownV in Figs. 1 and 3,
Fig. 5 is a side view of the table in its knock-down condition and reassembled in a compact package for storage or transportation, and
Fig. 6 is an end view of the knock-down condition of the table as shown in Fig. 5.
The top here shown is composed of two longitudinal sections 10 and 11 whose edges are in an abutting relation when assembled, and battens or cross members 12 and 13 arranged at the ends of the table and crossing the junction at the abutting edges of the sections 10 and 11, beneath which the said cross members are arranged. All these parts are separable. y
This top is supported and all the parts thereof drawn tightly together and held rigidly in proper relation for use by the legs 14, theupper ends of which carry cooperating fastening means to extend through the table top sections and the transverse battens forming the top. As an example of one form of fastening means, the present embodiment shows a bolt 15, having a T head, threaded longitudinally in the upper end of each leg 14. The legs are preferably made of tubular metal and each have fitted and secured in'their upper ends a boss or plug 16, each boss having an intermediate iiange extending around the same to provide a shoulder or flange 16a projecting laterally from the respective legs 14 to be engaged by and to support the top.
The top sections are formed with apertures 17 at corners corresponding to the corners of the assembled table. These apertures 17 may be in the form of elongated slots made directly in the sections 10 and 11, but, where the sections are of wood or other relatively soft material, the apertures may be enlarged openings covered by a metal plate 18 counter-sunk in the sections, each plate being formed with a slot 17a to permitthe head of a T-bolt to be inserted therethrough, as shown in Fig. 2. After inserting the bolt 15 in the slots 17 from the underside of the top their heads are turned at right angles with respect. to the slots to be `received in a correspondinr recess 19 in the plate 18. Itis therefore o vious that when the heads of the bolts have been turned to register with the corresponding recesses 19 and have been seated in said recesses, the several parts composing the top may be rigidly unlted to each other and to the legs 14 by turning said legs, the parts of the top thereby being clamped between the shoulders 16a and the heads of the bolts. It is, of course, understood that the battens are formed with openings 20 which align with the apertures 17 and into which the upper end of the respective legs or the boss partially extends for the purpose of centering the legs in position and giving added strength to the construction. rlhe bolts 15 may be held in the boss against removal by pins 21 extending transversely through their inner ends.
To holdV the several parts which compose the top in an assembled relation while the legs are being applied, as well as to further reinforce the table when all the parts thereof have been assembled, means of suitable nature are provided for `securing the top sections 10 and 11 adjacent their abutting edges, and the lower' members or battens 12 and 13 to each other. The means here shown comprise lock-bolts 22 each of which is in the form of a T-head bolt having downwardly extending prongs on the ends of the arms of said head. The shank of the bolt is received between opposing notches in the abutting edges ofthe Sections 10 and 11, which form an o ening when the sections are assembled for tab 23, respectively, engage in depressions in said sections. There are preferably two of said lock-bolts 22, one extending through an opening in the center of each batten, wingnuts 24 being provided to hold the parts together. It will thus be seen that by tightening the wing-nut 24, the top sections and battens are clamped together along a medial line of the table, and may1 thereby be maintained rigidly in assem led position while the legs are being applied and tightened, or while said legs are being loosened and removed, as well the rigidity of the top when the parts are assembled. The provision of fastening elements for securing the top sections to the battens or lower members of the top along the medial line of said sections also contributes to the durability of the top as well to the lightness of the construction thereof, since they substantially reduce the tendency of the top sections to become warped when made of light material.
To knock-down or disassemble the table,
le purposes, and the prongs to slacken the bolts until the T-heads:
thereof can be removed` through the slots 17, the legs being thus disconnected, and
(2) toslacken the nutsQ-i inorder that the prongs 22 on the T-heads of theV bolts 22 may be disengaged from the top sections, so that the section and batten may be separated and taken apart. V
lVith parts thus disassembled they may be` rearranged to form a compactV bundle or package for easy transportation orV storage.
tThis is accomplished by arranging the sections 10 and 11 .face to` face (see Fig. 6)
and positioning the battens thereagainst one along each longitudinal side of the one of said sections. Thus the parts which form the top are held together in such a Way. asto overcome any tendency to Vwarping when they are in a stored relation. The lock-bolts are then positioned with 4their T-heads through aligned openings a located in the middle of the top sections 10 and 11 near the said edges thereof, and through the corresponding openingsfin the battens aligned with the Aopenings a whereby the sections and the battens may be initially secured together by tightening up on the wingnuts The legs 1-1V are then placed sidey by side in thespace between the 4tWobattens 12 and 13 and in juXta-relation with one of the top sections and are held inv place by two bars or strips of metal, or other material, disposed to extend transversely across and overlie the ends of the legs. The strips or straps 25 are secured at their ends by bolts, 2G removable extendingthrough the bat-tensV 12 and 13 and preferably7 but not necessar-` ily, through the sections l()O and 11, as shown in Figs. 5 and 6.
The intermediate portions of the straps Q5 are offset outwardly to accommodate the thickness of the legs and these portions are further formed with slots 27 in which the flanges or shoulders 16a protrude, t thus securely maintaining the legs avainst displacement. For compactness, the the legs are alternately arranged so that there is two slots 26 in each strap 25. i
F or convenience in transporting the table,
a'handle 28 is provided at the center `of a longitudinal edge of one of said battens so that it will project upwardly into position to be readily grasped when the parts of the table are in the compact form shown inFigs.
5 and 6, but this handle will be out of the way and obscured when `the table is assem anged ends ofV by slaekening the bolts 15 until` the legs, can be removed, and, by slackening the nuts` 24; The operationv of assembling the table for useis equally simple,it being only necessary to assemble the top, insert the upper ends of" the legs therethrough and` tighten the bolts 15.by turning the legs, and in case y further rigidity is desired` for the top,
tighten the wing-nuts 24; When the table is assembled, the strap 25 maybe suspended from the underside of `the table top by the bolts 26 in order to prevent them. from` being misplaced.
