are employed as ,adjunctsto the principal connecting means betweenrthe: 'end frames and the tie-member, and further aims are to so relate thesellinks with other parts as to causethem to efiectivelyguide the end'members toward their horizontal positions from their vertical positions and vice versa, and
to cause said linksto relatively brace the end frames and thetie member. 1 A further object isto provide an end frame of unusuallysimple and inexpensive con- ;2 struction, yet so formed that it will berigid and will adequately perform the function for which it is designed.
A still further object is to provide a unique.
detachable connection between the. end
i 3 frames and the tie member.
With the foregolng in view, the invention resides in the novel subj ectmatter hereinafter described andcIaimed, description being a(:-
compli'shed by reference to the accompany- Fig; 1 is a front elevation partly broken away and in'sectionf i Fig. 2 isa top plan view partly broken away and in section. V 1 I Fig. 3 is a fragmentaryfront elevation showing one of the end frames folded to "a position under the tie member and indotted lines illustrating another position'which the end frame assumes before reaching the full line position illustrated in this view. 'Y i Fig. 4 is a vertical transverse sectlonal .view on line 4-4 of Fig. 1. e v
Fig. 5. is a perspective view illustrating the separable connection between the: t e
of ,female and male portions FM carried by said bars-respectively and confined be-.' tween the inwardly projecting flanges 10. of
ATENT? ,oF 'Ice f member and one end frame, the two portions thereof being in juxtaposition Fig. 6 is a view similarto Fig. 5butshowing the two portions of the separable connection engaged with eachother.
The form of 'construction herein disclosed has provento beeliicient and desirable from all standpoints, and is therefore preferably followed. However, within the scope of the invention as claimed, variations may be made.
Forl illustrative purposes, the specific construction which has been illustrated, will be described. 7 v l a Two-end frames E are shown held in spaced "relationwith each other by a tie bar 8 and novel connectingmeans between said frames and bar. Between the'frames E, a hammock or glider H has been shown in dottedlines,
and suspenders such. as the chains C :are employed for hanging the hammock or the like; H from' the upper portions of said framesE. The frames E are twins and hence a description of one will suffice. 'Ifhe same is true of the. connecting means between the frames E and the bar 8.
End fraineE embodies a'horiiontalibase bar 9 of angle metal, avertical relatively wide 'channel bar-10 having its lower end centrally secured to said base bar 9, and. a
. top bar 11 of angle metal having its central,
portion rigidly secured to the upperend of said channel bar 10, the end bar llvbeing of suitable construction for engagement with the suspenders G. Byformingthe end frame E7111 th1s manner, it is of unusually simple and inexpensive nature, yet itwill well. perform all 'functions for which it is designed. The separable connection between the channel bar'lO and the tie bar 8, consists said bar 10. The details of these connecting portlons F -M will be hereinafter fully described but at present it will sufice to say thatthese connecting portions. are disengageable from each other when the end frame E is moved from the normally vertical position :shown in Fig. 1 toward the horizontal position shown in full lines in Fig. 3.
Two links 12 eXtend longitudinally of an end portion of the tie bar 8 and have their inner ends pivoted to the front and rear sides of said bar respectively, as indicated at 13. The links 12 diverge outwardly and have their outer ends pivoted at 14; to the flanges 10 of the channel bar 10, and when in their normal positions, the links 12 are inclined outwardly as seen in Fig. 1. Thus, the inclination and the divergence of the links cause said links to relatively brace the end frame and the bar 8 in a number of directions.
Attention is invited to the fact that the relation of parts is such that the links 12 may swing downwardly and inwardly from the normal position shown in Fig. 1 to the reversed position shown in Fig. 3. Moreover, the relation is such that as these links near said reversed position and the end frame E nears the full line horizontal position shown in Fig. 3, said frame E may move toward the links, as will be clear from this view. The result is that when the frames E are to be moved from their normal vertical positions, they may be horizontally disposed beneath the end portions of the bar 8, allowing the entire supporting frame to assume compact form for shipment or storage. A small notch 15 is preferably formed in the base bar 9 to receive the bar 8 when the frame E is in its horizontal position, and it will be observed that when said frame is in this position, an end portion of said bar 8 extends longitudinally within the Channel of the channel bar 10, and both links 12 are also housed within said channel. Not only do these links assist in guiding the frame E to the folded position of Fig. 3, but when the frame is to be set up for use, said links perform a reverse guiding function so that the members M-F may be readily interengaged.
In forming the member M, I make use of a single sheet metal plate of suitable thickness. This plate is bent substantially upon itself at .its transverse central portion to provide a sleeve 16 adapted to be secured around an end of the bar 8 by rivets or the like 17. The two ends portions 18 of the metal plate are extended in the same direction from the sleeve 16, preferably upward, and are tightly secured to each other by rivets or the like 19. Portions of these plate ends 18 at the outer end of the sleeve 16, are bent laterally in opposite directions to provide vertical flanges 20 whose outer edges preferably converge downwardly as seen most clearly in Figs. 4: and 5.
In forming the member F, I make use of a second sheet metal plate 21 of appropriate thickness. In this plate, I form a substan tially rectangular opening 22 by a stamping process. Although this opening is of ap proximately rectangular form, its opposed vertical edges preferably converge downwardly to the same degree as the outer edges of the flanges 20 above described. Formed integrally with these vertical edges of the opening 22 are two flanges 23 which are inwardly offset from and parallel with the plane of the plate 21. At their upper edges, these flanges 23 are free from the upper edge of the opening 22 but the lower ends 24 of said flanges turn toward and are integrally joined to the lower edge of said opening 22.
By forming the members MF in the manner shown and described, they are of simple and inexpensive construction, yet they may be readily engaged or disengaged and will be eflicient for the purposes intended.
From the foregoing, taken in connection with the accompanying drawings, it will be seen that a generally improved and simplilie'd construction has been provided, and attention is again invited to the fact that variations may be made within the scope of the invention as claimed.
I claim i 1. In a hammock frame, an end frame embodying a vertical channel bar, the side flanges of said channel bar being disposed at the inner side of the frame, a horizontal tie bar to extend between said end frame and a twin thereof, separable connecting means between said tie bar and said channel bar and confined between said inwardly directed flanges of the latter, and diverging links pivoted to said bar at their inner ends and pivoted to said-flanges at their outer ends.
2. In a hammock-supporting structure a vertical end' frame, a single substantially central horizontal tie bar to extend between said frame and a twin thereof, separable connecting means between an end portion of said bar and the lower end portion of said frame, the upper end of said frame having means from which to suspend a hammock seat above said tie bar, two links extending longitudinally of said end portion of said tie bar, means pivoting the inner ends of said links to the front and rear sides respectively of said bar, and means pivoting the outer ends of said links to said lower portion of said end frame, the latter, the pivots and the links being so related as to allow downward and inward swinging of said links to reversed position and movement of said frame to a horizontal position under said tie bar as said links near said reversed position, said links normally diverging from their inner to their outer ends to hold said end frame against canting into a vertical plane oblique to said tie bar.
3. A structure as specified in claim 2; said links being inclined when in normal position to hold said end frame against canting into an inclined plane.
4c. In a hammock-supporting frame, two vertical end frames having front-to-rear supporting bases at their lower ends and provided with means at their upper ends for suspending a couch hammock, said end frames being provided near their lower ends withfixed coupling members, rigid horizontal spac ng means extending between the lower portlons of said end frames and rearwardly spaced from the front ends of said bases, ad-' I dltional coupling members secured to the ends of said spacing means and downwardly insertible into said fixed coupling members of the end frames, and front'and rear links pivoted at their inner ends to said spacing means on horizontal axes spaced inwardly from the ends of the latter, the outer ends of said front and rear links being spaced horizontally forward and horizontally rearward from said fixed coupling members respectively and pivoted to said-end frames on horizontal axes, whereby said links will guide said end frames to horizontal positions under said spacing means when the frame is to be folded, and will guide the two sets of coupling members into engagement when the end frames are again returned to their vnormal vertical positions.
In testimony whereof I'have hereunto affixed my signature.
