This. invention relates. to. supports and particularly to devices of the type consisting of abar or rod. adapted. to support garments. in a clothes closet. or adapted to be used as an exercising support. bar. In fact, the invention is in. the structure. of the. bar orrOd and it is intended for use. for any purpose desired.

Ithas been the object of the present inventors to provide. a. bar or rod type of. support which readily extensible, that, is to say which may be adjusted as to length and which will thereby readily fit. in between the end walls of a closet. or, the. frame. of a. door or. which may be utilized between the walls of an automobile. The features of. extensibility are such that the rod may be. quickly and. easily fitted tov the space in which it is. inserted.

It has. been a further object of the present inventors to provide. an extensible rod, the sections of which. may be adjusted to substantially the correct length to fit between the walls or door frame, and which, when fully extended after ad'- j ustment will exert pressure endwi'se so as to be wedged tightly in. position. In the accomplishment of this objective, the rod has been constructed so that its sections will snap to extended, aligned and fitted positions. Further the device is inclusive of locking means for preventing aoci'dental release or displacement from fitted position.

It. has. been a. further object of" the present inventors to provide an extensible rod or bar of this character which is. inclusive ofv end members. which are capable of making frictional contact withthe; walls, or the door frame and. which. will not require the use. of any attaching means which would otherwise mar or damage the walls or. door. frame. It is intended, however, that as an. alternative in those cases where some slight indentations will not be noticeable. or, where the. rod. is. more or less, permanently placed in position that spurs may be incorporated which will. supplement the frictional, holding. action. of the. end members.

It has been a still further object of the present. inventors to provide a bar structure of this character which is exceedingly strong, that is in which the cross-section and the interrelation of the sections making up the rod is such that the rod is exceedingly stiff and reinforced.

Other objects relate to the specific structure of the device wherein there is flexibility between the end members and: the bar sections which will permit, the installation of. thebar by the act. of placing the. respective sections in approximate position, latching them together centrallyand. exerting pressure centrally and laterally of the 2 Claims. (Cl. 211-123)" rod, so as. to cause, endwi'se pressure and. to cause wed'ging of the sections. in position. when they are. aligned.

Further objects. and advantages will be more fully set forth in the description with reference to the accompanying drawings inv which Figure l is. a fragmentary view of the upper part of. the door frame or, cupboard space illustrating the bar in position- Figure 2 is a sectional view taken. on. line 2-4,. Figure 1', showing, the sections of the bar in position, about. to. be installed. that is just prior to. the exertion of pressure centrally of the membersand. before alignmentv thereof.

Figure. 3 is a fragmentary enlarged view of. the device, certain. of the parts. being broken away and shown in section for more clearly illustrating the structure.

Figure 4' is a fragmentary front view of the device illustrating the means for connecting, the sections. and further detailing, the structure of the end plates.

Figure 5 isa fragmentary view showing the adjacent' ends. of the sections and illustrating the latching means.

Figure 6 is, a sectional. view taken on line 6--6, Figure. 4,. detailing. the cross-section of the. bar sections and detailing, the locking. clip which holds them. in. assembled relationship.

Figure 7' is a. fragmentary view illustrating, the adjacent. ends. of. the sections. in. hooked. position just. prior to. alignment and. locking.

Referring tothe. drawings, the respective sec.- tions of the device. are generally indicated. at l0. In order to. provide adequate rigidity and stiiiness, the. sections. are fabricated. of channel members. As shown in Figure 6, the cross-section. of the. bars. is curved as at It and longitudinal. flanges l'2. are included. Each of the sections includes. atone end an abutment or clamping plate I3. presenting a fairly large area for engagement with the. walls. [4. or frame of the. door- (Figures. 1 and 2)... These end plates. are pressed tram sheet metal to provide ribbing and. toprovidea marginal lip, l5. Asheet l6 of sponge rubber constituting a. facing. is secured to the outer face. of each. end plate. Adhesive. may be used for securing these rubber facing elements in position.

Each. plate includes a depression ll. centrally thereof. this. depression being rectangular in shape and having anattaching bracket or. member t8 seated therein. Each attaching bracket includes a. bottom; portion I-9- and side walls 20; Qpposite side, walls are extended as at 21 to: provideears which receive the outer end of the. bar

- section. A. screw 22 is: passed through-these ears and through slots 23 in the curved portions of the bar sections immediately adjacent their ends. Through this arrangement the bar may shift toward and from the end plate. The end of the bar is in contact with a plate element 24 and a curved leaf spring 25 .is inserted between the plate 23 and the base portion l8 of the bracket. The purpose of these spring elements will be more fully apparent later.

, If desired, spurs 26 may be struck from the base I9 of the brackets l8 at opposite sides there- 1 of. These spurs project through apertures 21 in the end plates. The spurs are of sufficient length so that they pass through and slightly beyond the sponge rubber facing. These spurs can be utilized for additionally anchoring the end plates in position where added attachment means are required. The spurs, however, are not necessary for the large area of sponge rubber facing is suflicient to frictionally hold the bar in position when endwise pressure is exerted on the plates as will be described later. 7

One of the sections includes a series of apertures 28 disposed along its length centrally of the curved portion thereof. The other rod or bar section includes a latching hook 29 (Figure '7). This hook element is secured in position by having its shank portion 35 extending through traversing I loops 34 struck up from the curved central portion of the bar. In other words, these loop portions are pressed out a sufiicient distance to permit insertion and fastening of the shank of the hook member. The extended end of the hook member curves outwardly, that is laterally of the bar and thenendwise as at 30. The shape of the hook enables it to be inserted readily in any one of the series of apertures in the other bar as illustrated in Figure 7.

A locking element 3| which is in the nature of a clip .is slidably mounted on the bar section which includes the hook. This locking clip is of the same general cross-section as the bar section, that is it fits or nests in the section. It includes overhanging flanges 32 which retain it in position on the side lips or flanges of the bar. The flanges 32 are. spaced from the body of the clip a sufiicient amount to permit the clip to overhang the flanges of both sections (Figure 6). Thus, the clip may be slid into position overhanging the flanges of both sections and, in conjunction with the hook, will latch or look the sections against lateral displacement. ,A set screw 33 is provided in the clip for securing it relative to the sections when the clip has been'slid to locking position as shown.

In mounting the device in position, the user selects a desired aperture and the latching pin is inserted therein as shown in Figure 2. The

sections are at this time disposed with their end plates in contact with the frame of the door or the end walls of the closet. By exerting lateral pressure centrally of the connected sections they are pressed into alignment. This is possible since the bar sections may move relative to the plates and may exert pressure against the leaf springs, the spring pressure being exerted through the bracket into the end plates and being responsible for causing a frictional engagement with the door frame or wall. It will be observed that the sections, when pushed to aligned position, tend to snap into place. When they are thus aligned the user slides the locking clip into position overhanging both sections. In placing the device in position the flanges of the sections are disposed vertically so that the device is exceedingly rigid 4 and the assembled relationship or nested position of the sections tends to furtherreinforce the device.

Thus, it will be apparent that the user may quickly and conveniently install the bar or support rod at any height desired in the closet or in the door frame. This is of great advantage in that the bar may be adjusted to suit the height of children and makes it possible for them to place clothes hangers on the bar. Also, the device may be used in an automobile by utilizing smaller end plates. Further, it may be used as an exercising bar and will easily support the weight of a person. The range of extensibility obviously is variable depending upon the length of section employed. In any given assembly, however, the extensibility may vary from substantially half to full length.
