Y ‘ Application March 6, 1945, Serial No. 581,284 3 Claims. (01. 287—3) 2 This invention relates generally to collapsible closed in Figs. 1 and 2, a cane or walking stick I0 and in Fig. 5 a tripod II. It will be under or foldable devices and more particularly to a deviceghaving foldable means joining together sections of the device. ' stood, however, from the following description that the invention is applicable to other articles or devicessuch as, for examples, umbrellas, table legs, etc., wherein it is desired that adjacent sec ‘ It is an object of the present invention to’ join together sections of a member, such as, a rod, tions be disposed either-in tandem and secured staff, or stick by means of a foldable con nection whereby the member may be folded with in this relation or side by side to con?ne the the sections in substantially parallel relation or article or device in less linear space. The cane or walking stick I0 is seen as com the member extended with the sections connected l0 prising two sections I2 and I3 joined together together in alinement. , _ . It is a further object of the present invention at I4. A handle I5 may be attached to section to provide a joint for connecting, together two I2. The abutting end portions I2a, and. I3a of sections of a member, the joint having ‘a part sections I 2, I3 are hollow to accommodate parts ?xed with relation to one of the sections and of‘ the swingable joint connection generally indi~ another part slidable Within the other of the cated by the, numeral IB. Connection I6 comprises a pin or shaft I'I rig sections, the two parts being pivotally connected idly secured within the hollow I8 of section I3. to a link, so that the two sections may be brought Shaft I'I has a reduced threaded projection i9 into side-by-side relation, and the ?xed part and link being extendible within the said other of 20 extending without section I3 and being provided with a pair of spaced perforated earsor lugs 26 the sections so that both sections may be brought to which is pivotally or swingably connected by into contiguous alined relation. means of pin 2| one end of a link 22.

Shaft 25 is arranged for sliding within bushing 3| and is provided with an en invention consists can be variously arranged and largement 33 at its free end providing a stop adapted to abut against the inner end of bushing organized and that the invention is not limited to the precise arrangement and organization of 35 3|. Link 22 is of such siZe as to pass through the the instrumentalities as herein shown and de threaded opening of bushing 3| following shaft scribed. 25; and the threads of projection I9 are adapted In the drawing: to engage the threads of bushing 3|, as clearly Fig. 1 is a View illustrating a cane or walking stick embodying the invention; 40 Fig. 2 is a view of the stick shown in Fig. l, in folded condition; Fig. 3 is a longitudinal detail sectional View of the center portion of the stick shown in Fig. 1, and disclosing the connecting joint; Fig. 4 is a detail sectional view of the center portion of the stick with parts of the connecting seen in Fig. 3. Let it be assumed that the sections I2 and I3 are in alined abutting relation as seen in Fig. 1, at which time projection I9 is in screw-threaded engagement with bushing 3| and shaft 25 and link 22 are housed within the hollow 3!] of member I2 beyond bushing 3|. If it is desired to fold the cane or walking stick so as to place he same, say, for example, in a valise, suit case or the like, section I2 is dis joint extended relative to the sections of the stick engaged from section I3 by unthreading pro and the sections disposed at an angle with respect 50 jection I9 from bushing 3| and pulling on section to each other; and Fig. 5 is a view of a tripod embodying the in I3. Shaft 25 projects from the socket or bushing vention, one of the legs being seen in partially 3| and the link 22 and extension It are wholly foldable condition. ' Referring now more particularly to the draw ing which by way of examples, only, there is dis disengaged from section I2. Fig. 4 shows the disposition of the connecting 55 joint parts when the sections I2 and I3 are rel 2,409,452 4 atively at right angles during the folding opera tion and Fig. 2 shows the relation of the sections of the cane when the latter is almost in complete folded position. The tapering or conical open ing 32 prevents possible binding or impediment of parts of the joint, particularly at the pivoted points, during withdrawal thereof. Referring to Fig. 5, it is evident that substan tially the same type of connecting joint may be employed for making the legs of a tripod foldable, As changes of construction could be made within the scope of the invention, it is intended that all matters contained in the foregoing de space permitting threaded engagement of said element and said extension. 2. In an article of manufacture two members, one of said members having a tubular internally threaded portion and being hollow beyond said portion providing a cavity, and means connect ing said members together at said threaded por tion and at an end of the other of said mem bers, said means comprising a shaft movable in said cavity and extendible from said threaded portion, stop means preventing said shaft from being withdrawn from said threaded portion, an element ?xed to said end of said other of said members, said element having a threaded ex scription or shown in the accompanying draw ing shall be interpreted as illustrative and not 15 tension adapted to threadedly engage said threaded portion, and a link pivotally connected in a limiting sense. to adjacent ends of said shaft and said extension, Having thus described my invention what I said shaft and said link being adapted to pass claim as new and desire to secure by Letters Patent, is: through said element into said cavity permitting 1.
