Claims. (Cl. 311-84) This invention relates in general to folding stands usually made of lightweight materials such as to provide a support for a basket, a bassinette, an auto bed, a port able bath and the like although it may also be made of stronger materials and of larger sizes as a support and a display holder for other articles. In foldable stands as heretofore used, the parts are hinged or otherwise connected together so that the legs in folding do not fold compactly against the top or against the other legs, but rather engage each other and extend at an upward and space consuming angle from the top itself and from each other, such that the folded stand cannot be compactly collapsed for compact storage or shipment.
The present invention overcomes these dilficulties and objections by providing an improved offsetting hinge for each of the legs and foldable collapsing leg stays so that the legs are firmly held in extended position at right angles to the top and also are foldable compactly in overlapping relation at the under side of the top and substantially parallel thereto. Although connected for joint movement by cross pieces, the upper ends of the legs are connected at the tops by offset end bars for providing additional space at the ends of the top for receiving a bassinette or other articles longer than the top itself.
An important object of the invention is to provide a folding stand in which the legs are pivoted to the top by an oifsetting hinge construction which permits the legs to fold more compactly at the under side of the top and in engagement with each other.
A further object of the invention is to provide improved means for guiding the folding and extending movements of the end pairs of legs in unison and in holding them locked in extended position so that the stand will not collapse.
Still a further object of the invention is to provide a compactly folding stand which has means extending above the top for extending the effective area thereof so that a basket or other article larger than the top may be supported thereby.
Still a further object of the invention is to provide a lower support for a shelf or tray as a part of the folding stand.
Other objects of the invention will appear in the specification and will be apparent from the accompanying drawings in which,
Fig. l is a perspective View of a folding stand in accordance with this invention in extended position,
Fif. 2 is a perspective view of the stand of Fig. l in folded position; and
Fig. 3 is a detail perspective view of one of the offsetting leg hinges.
In a folding support for articles which are used periodically, such as baby baskets and baths, wash baskets and other containers for clothing, display containers and the like, it is desirable that they be compactly folded so that when not in use, they may be stored where they will occupy a small space from which they do not protrude 0b jectionably when they are folded as awkward sprawling and extension is often caused by improper connection of the hinged legs and other parts, but the present invention overcomes these objections by providing the leg structure mounted on offsetting hinge plates which causes the legs at opposite ends to fold compactly against the top and supported by and against the legs from the other end.
Referring now more particularly to the drawings, this invention is illustrated in connection with an article supporting top 10 and four legs 12 disposed near the corners of the top. The top may comprise sidebars 14 connected near the ends by cross bars 16 firmly joining the side bars near the ends thereof. If desired, a top panel or cover plate 18 may be attached to the upper or lower side of the frame formed by the bars and cross pieces of the top. This plate may be heavy cardboard, thin sheet metal, laminated wood, fiber or other material which is both light and strong.
The legs are attached to the top near the ends of the side boards by means of offsetting hinge plates 20, each angular or L-shaped. Each plate is attached at the relatively inner side of a leg 12 by a rivet 22 which extends through the plate at the angular portion thereof and into or through the post. One end of the L extends parallel to the post and in the L-shaped portion, a screw or stud 24 is inserted into the post, the rivet 22 and the stud holding the hinge plate tightly in connection with the post. An extension 26 of the hinge plate is at right angles to the portion secured to the leg 12 and has an offset 28 in this extending portion through which a pivot 3t) extends through the plate and into or through the side bar 14 of the top adjacent the end thereof, the offset 28 freeing the leg and the side bar from engagement with each other and providing a space for the ends of the rivet 22 and the pivot 30 to pass without contact with each other. The extension 26 forms a spacing ofiset between the leg and the side bar 18 when the legs are folded with respect to the top and with respect to each other.
Also connecting each leg and its corresponding side bar 14 is a leg stay having a part 32 pivoted at one end to the side bar 14 at a short distance fro-m the end and an other leg stay part 34 pivoted at one end to the leg and at a distance below its pivoted connection with the end of the side bar 14 when the stand is in supporting position. These two part 32 and 34 are connected together by a pivot 36 in the end of one part as 34 so that the other part 32 overlaps the part 34 near the pivot and these parts are provided in the overlapping portion with indented and engaging edges 38 and 46 respectively which in interengage when the stay parts are in alignment with each other to limit their movement in one direction.
A projection and depression 42 is also formed in the end of one part 32 and near the end of the other part 34 which inte-rengage and hold the stay parts in parallel position until they are manually disengaged by a folding movement at the pivot 36 in a well known manner. The upper ends of the post 12 preferably extend a short distance above the top 10 and its cover plate 18, if it has one, and to the sides outwardly from the ends of each pair of legs, a cross bar 44 is secured in outwardly offset relation by short connectors 45 extending between the inner side of the bar 44 at the ends thereof and the relatively outer side of the legs at the upper ends thereof. By connecting these bars 44 in an offset relation, a basket or other receptacle which is longer than the actual length of the top may be supported thereon and between the bars 46, thus providing more space in this dimension of the stand. I
The lower portions of each end pair of legs 12 may also be cross connected and the stand strengthened by bars 48 intermediate the top 10 and the lower ends of the legs which provide means for upholding and supporting a rollers 50 which support the stand and for free movement upon the floorlor any other surface when it is in use and which also turn freely forcompact arrangement in folding the stand as shown in Fig. 2.
This stand has a general use particularly in households and may be used either as a temporary or a permanent folding stand with the added features that it is firmly held in its extended position against collapsing and is easily foldable into compact relation for storage and shipment since the legs are of a suitable length to overlap below the top and fold tightly together against the under side of the top and against the first folded pair of legs so that the stand can be stored in a minimum space when desired.
While a preferred construction has been described in some detail, it should be regarded by way of illustration and example rather than as a restriction or limitation thereof, as many changes in the construction, combination and arrangement of the parts may be made without departing from the spirit and scope of the invention.
