Y FOLDING TABLE.

v rlfhis invention relates to folding tables, and more particularly to folding tables which are of light construction and adaptable to be folded or collapsed while not in use and may be easily and quickly opened when the occasion necessitates.

.The principal object is to produce a folding table of the class described which is durable and steady .on its feet while atthe lo'same time being of such light construction as to make the burden of :handling it as little 'as possible. y

.Another object resides in providing a leg bracing and brace supporting structure which takes up all of the stress exerted from the legs through their respective braces when the table is in use thereby relieving the vtable top proper from any strain. e

Another. Objectis to simplify the process of opening by having the various legs positively related to one another -so that a force exerted upon any one of them with a tendency to draw it to an open position will automatically be transmitted to the remaining legs. to cause their opening ,to an extent substantially equivalent to that of the leg to which `the force is being exerted.

Another `object is to; so design the bracing for the legs that by the mutual cooperation yof the bracing for each set of legs, any force or pull exerted on one of the legs to open it will be transmitted throu h its own bracing to the bracingof oneo the-other legs to supply an additional force thereto that will materially facilitate the entire operation of opening all of the legs.

Another object is to provide a folding table which willbe 4compactly closed and so maintained when in storage condition-and whose legs will open to their standing position when released -by ,their`ownaction and lock themselves in a most rigid manner.

i Other and incidental objects will be pointed out hereinafter in the follow/ing description of what I now consider to bethe preferred embodiment 'of my invention, and

in the claims and drawings, in which:

The table in its'open or useful condition, as seen in Fig. 1, consists of' a table top 10 of light and rigid material whose edges fit into notches (Fig. 3) in rectangular frame member 11. This top may have a cloth or other cover, if desired, and it is held in place 1n 1ts frame by any suitable means, such as small nails or clips, not shown. Resting firmly against the under surface' of the top 10 is a channel guiding member 12 'having horizontally extending edges 13 and turned over 'ends forming clips l14 by -which'it is fastened to frame 11. Screws 15 maybe used to secure this fastening.' This channel guiding member not only gives rigidity to frame 11 and supports the center of the table top, but it forms tracks in which racks 16 and 17 travel. The channelis in-v dependent of the table top and is ofsuiicient strength and stiffness to take up` all of the forces exerted by the legs of/the table when -the table is in use. -Mid-way between the ends of this channelmember. is a stud 18 on y which pinion 19 revolves when the legs are i opened and closed. Pinion 19 meshes with both racks 16 and 17 at all times.

Braces 2O and 21 foiI one pair oflegs 22,

23, are fastened together at one end and are pivotally connected with rack 16 by means ofl plate 24 and pin 25, Fig. 9. These joined guiding member. Each of the braoe memi U0 bers 20 and 21v are pivotally connected to ends of

braces

20 and 21 also carry a runner` it is folded, as seen in

legs

22 and 23 respectively by any suitable means 27, such as bolts, rivets or screws.

Resting against the open side of channel member 12 is a plate 28 held in place by a nut 29 on stud 18 and by two

curved portions

30 and 31 which bear lightly against the

racks

16 and 17 respective y. Plate 28 has a cut out portion 32 into which plates 24 of the leg braces run and by which they are maintained lfrom lateral displacement when the legs are open. These cut out por tions limit the travel of the free end of the leg braces and may be of any desired length,

but the open position illustrated in Figs.

2, 3 and 4 has been found to give satisfactory results, for the vertical components of the forces transmitted through the braces from the legs when the table is pushed in a direction lengthwise of channel member v12 are neutralized. Therefore, by the centrali.- zation of the points of force application the table top can never be called upon to stand any strain and it will not bulge at its center. Completely covering plate 28 is a latch plate 33 pivoted about stud 18Jand continually urged' counter-clockwise Fig.` 5 by spring 34. In its normal position lthis latch is maintained from rotation by means of legs 35 which extend therefrom over the outside edge of channel'member 12. This latch has two noses having sloping edges 36 by which it is rocked by plates 24 at the ends of

racks

16 and 17 when they approach each other in preparing the table for use. The resistance oli'ered by spring 34 when plates 24 encounter the sloplnv edges 36, serves to cushion the opening eort of the legs and thereby eliminate jar and noise. Upstanding edges 37 are provided for rotating the latch member when it is desired to release the latch from locking relation to free plates 24 in order that the legs may be folded.

Legs 22 and y23 are set into or are at tached to a cross-piece 38 'which is pivoted along its inner edge and at its ends to frame 11 by means of

pins

39 and 39. In the present embodiment these pins are each fastened to the cross-piece byv means of a plate integral therewith and they rotate in sockets or bearings in the frame, but a reverse relation could be used with the plates fastened to the frame without entailing any changejn my concept or' invention.

Leg 22 is situated close to a corner so that it will lay along one ed e of frame 11 when ig. 5. Leg 23 is a short distance away from its corner in order to allow le 40 op osite it space between itself and the rame w en the table is closed.4

Legs 40 and 41 and cross-piece 42 are mounted and placed on their side of the table similar to

legs

22 and 23 and cross piece 38, so that both pair of legs assume a close'and compact relation when the table is closed, as clearly shown in 5, 6 and 7 -slidin v ess cfg Braces 43 and 44 for

legs

40 and 41, respectively, are connected to rack 17 1n a manner similar to the connection of

braces

20 and 21 with rack 16, and they are identical in construction and shape to braces 2O and 21, respectively.

Legs

22 and 40 have cut-out portions 45, that may be of suflicient depth to accommodate the outer ends of braces 2O and 43, respectivelgr and the pivot screws 27 are placed preera ly near the outer edge of the legs, as are also the pivot screws 27 in

legs

23 and 41 for

braces

21 and 44, respectively. The advantage of this arrangement is readily apparent-` from an inspection of Figs. 6 and 7, which show that the angle described by the table top and a line drawn through pivot points 25 and 27 is of maximum ma 'tude for the size of table illustrated. o further aid in opening the table, braces 20 and 43I are placed underneath braces 44 and 21, respectively, so that when any one of the legs is raised the legs on the other side ofthe table will have an additive prying force applied to them through the contact of the braces, and the procopening the table is rendered more easy.

l. When the table is fully opened the braces are in close contact, as seen in Fig. 3, and this creates a very stable condition.

The two pairs of braces 'are positively connected by. means of their

racks

16, 17 and pinion 19 so that any movement of one pair of legs will produce a corresponding movement ofthe other pair ofA legs. While this is a desirable result, it is obvious that similar correspondin movements would be roduced if the rac s were merely lain slides instead of'toothed slides, for e cooperative relation of the braces would produce substantially the'same results.

When the legs are vclosed as shown in Fig. 5, lthey are locked from displacement by means of a latch 46 which has a 47 that bears against plate 24. 1s pivoted on a lug 48v and may be moved out of the ath of 49. T is rod as two collars fixed thereto and a spring 50 serves to continuall urge the latch .into latching position. o prepare the table for use, it is only necessary to hold it in a position with its legs4 on the under side and press on button 51 and the legs will immediately be released and assume the position shown in Fig. 4 and be then locked by latch 33. v

Springs, such as those desi ated by numeral 52, may be provided to he p accelerate the o ning of the legs lif such expedient is thoug t useful, and Afor the purpose of rplilojection y is latch plate 24 by depression of rod Simplicity I have chosen to illustrate such otally connected with one'of each of the convenience and may be varied to suit the aesthetic orpractical requirements of thetrade, but the proportions illustrated have been found to give satisfactory results and to allow people to sit closev to the edge of the table without interference with the leg braces. In this respect as well as in many others my invention is capable of a wide variation and relationship of parts without departure from the nature and principle thereof and I do not restrict myself unessentially in the foregoing or other particulars, butl contemplate r such alterations and modifications within the scope of theappended claims as may be found advisable. 1 What I claim is 1.
