Patented May 12, 1942 UNITED STATES PATEN T FF [CE 2,282,689 I MOVABLE SUPPORT Butler Amos,- Boston, Mass. Y Application m 1, 1940, Serial No. 332,655
This invention relates to animprovement in a movable support of the type which can be 8 Claims.
pushed along and will serve as a .support for the user when in motion or at rest. Such a support is of value not only for those people who are infirm and have difficulty in walking or standing butalso for anyone desiring to rest from time to time as, for example, an attendant at'a football or baseball game or at any spectacle where seats are not provided or are not available.
The present invention is a further development of that shown in my copending application Serial No. 287,730, filed August 1, 1939, which matured into Patent No. 2,224,246 on December 10, 1940 and has as its primary object the. provision of a movable support so constructedflthat, when not in use, it can be collapsed to facilitate storage or transportation; and that it includes means by which it is rigidly secured in both-operative and collapsed positions, all as will be hereinafter described and claimed.
As illustrating this invention one embodiment isshown in the accompanying drawings where- Fig. 1 is a view in side elevation of .-a movable support embodying this invention;
Fig. 2 is an end elevation of such support;
Fig. 3 is a top plan view of suchsupport when collapsed; 1
Fig 4 is a side elevation of the collapsed support;
away of a detail of such support; and
faces of a sleeve and collar which when engaged jabovethe s'leeve.
Fig. 5, limit the upper movement of the sleeves I posite notches 29 and 30 and the upper face of the collar v28 has diametrically .opposite posts 3l. Tlee interengagementof the notches and posts hold the sleevej2l against rotation and the sleeve is clamped [insuch position by a nut 32 meshing with a threadedlnipple 33 fixed onto the leg I! The nipples. 3,3, as shown in The legs H are rearwardly inclined and the crossbars 26 are parallel, the upper barbeing shorter than the lower bar so that the side frames are inclined outwardly. Thus the support stands firmly and resists any tendency to tip either rearwardly or laterally when'set up as shown in Figs. 1 and 2, with the posts 3! seated in the notches 29.
When the support is to be collapsed the nuts 32 are backed away from thesleeves 2! and the latter raised out of .contact with the collars 28. The connecting unit 25 is then swung about the leg I! of one side frame H5 in either direction into contact therewith while the other side frame is swungthrou'gh 180 about that unit so 7 that the parts of the the position shown in Figs. 3 and 4 with the leg Fig. 5 is an enlarged View with parts broken v act to hold the support in the desired operative l5 connected at one end by means which rigidly hold the frames in thedesired position. Each the leg ll ofthe other side frame.
l6 of each side frame .nearand in advance of The sleeves 21 are then clamped .in contact with the collars 28 by tightening the nuts 32, with the posts 3| against undue movement relative to the connectside frame comprises a front'leg 16, a back leg ing unit 25. Thenotches .30, however, are longer than the posts 3| This is due to the fact that when the support is collapsed the side frames are at a slight angle to thecross bars since obviously it is impossible for them tobe in the same plane. The length of thenotches 39 is such that when the support is collapsed the ends of the posts soldered or otherwise secured at its ends to the The front leg !6 terminates in a fork 20 between the legs of which a wheel 2| is rotatably mounted upon a shaft 22 while the lower end of the back leg ll isbent outwardly and upwardly and carries a rod 23 which acts as a skid or shoe. 7 i v The unit 25 by which the side frames I5 are connected comprises a pair of crossbars 26 and a pair of sleeves 2'! to which the ends of the bars .3I will bear against those ends of the notches 30 which prevent any movement of the side frames away from the unit 25. The contact of the legs H with the brace bars I9 prevents any further movement of the side frames towardthe unit. Consequently the spacing of the other ends of the posts from the other ends of the notches (see Fig. 4) .due to the difference in length of the posts -31 and notches 30, does not result in any relative movement of side frames and crossbarsn collapsed it is so constructed-that it rests solely upon thewheels 2|, the skids .23 being raised as ,shown inFigA. The condition is attained in the support take.
sleeve 21 of the connecting unit 25. Hence when the parts are collapsed the legs I! are raised by the action of the connecting unit so that they take the positions shown in Fig. 4. 1
The support may also be provided with a seat which is preferably of the type that may be kept out of the way when the support is being moved. The seat with which the support It) is shown provided comprises a strip 40 of canvas, carpeting or the like, one end of which is looped around the upper crossbar 25, and the other end is secured to a roll or-rod 4|. Mounted upon the brace bars I9 are brackets 42 which may be of any suitable type to engage the ends of the roll 4| and prevent it from moving toward the legs While one embodiment of the invention has been shown and described it will be understood that the invention is not limited thereto and that other embodiments of the invention may be made without departing from the spirit and scope thereof, as set forth in the following claims.
