INTERLOCKING FRAME FOR SITANDS AND THE LIKE.

Application filed September 2, 1914.

T all whom it may concern:

Be it known that I, HAROLD E. DECKER, a citizen of the United States, residing at Cynwyd, in the county of Montgomery and State of Pennsylvania, have invented a new and useful Interlocking Frame for Stands and the like, of which the following is a specification.

My invention relates to improvements in interlocking frames for stands or other devices. 1

One form of my invention, shown herein merely as an example of the same, is especially adapted to form a support upon which to rest a baby while drying it after its bath.

The invention comprises a suitable frame, means for automatically locking the device in required position, a supplemental or positive look, a fabric top or support in the specific example shown, and other details of construction.

Referring to the drawings: Figure 1 is a perspective view of a folding stand in the open position. Fi 2 is a perspective view in the closed position. Fig. 3 is a fragmentary detail of the locking means and associated parts. Fig. 1 is a partly sectional view of same. Fig. 5 is an nd elevation of the frame sections shown in Fig. 3, in the closed position. Fig. 6 is a similar view in the open position. Fig. 7 is a side elevation of the outer of the two elements shown in Fig. 5. Fig. 8 is a rear end elevation of the same element. Fig.9 is a rear end elevation of the inner of the two elementsshown in Fig. 5. Fig. 10 is a side elevation of the same element. Fig. 11 is a section on 11-11 of Fig. 3. Fig. 12 is a fragmentary sectional detail on 12 12 of Fig. 8. Fig. 13 is a partly sectional view of the frame sections shown in Fig. 6.

Similar numerals refer to similar parts throughout the several views. I r

The framework of my improved stand comprises the two

interlocking frames

16 and 17, formed preferably from round metallic rods to form side, top and bottom extensions as shown. Substantially midway of the side extensions 18 of frame 16 there are provided the hinge elements or disks and 21, aperture'd at 22 and 23to receive rod 2% and provided with the short tubular extensions 27 receiving the ends of sides 18.

Side extensions 19 of frame 17 are similarly provided with cooperating

hinge elements

20 and 21, similarly apertured at 22 and 23 Specification of Letters Patent.

to receive rod 24:, and are provided with tubular extensions 26 receiving the ends of sides 19.

In assembling

frames

16 and 17 one side extension of a frame is inserted between the side extensions of the other frame. The hinge element of one frame thus engages the outer face of the cooperating hinge element of the other frame at one side of the stand, while at the other side of the stand the hinge element of the first frame engages the inner face of the cooperating hinge element. This is clearly shown in Fig. 3. Referring especially to said figure, it will also be seen that the

tubular extensions

26 and 27 project beyond the engaging faces of the hinge elements or disks, thus forming cooperating sockets or bearings for the disks at each side of the stand.

The outermost disks, 20, are each provided on their inner faces with the curved slots or grooves 28 adapted to receive pins 29 projecting from the faces of disks 21. Grooves 28 are cut into the faces of disks 20 at one end to a depth equal to the length of pins 29 and gradually rise to the faces of their respective disks at the opposite ends of the grooves. The inclined surfaces of each pair of grooves are oppositely arranged. That is, the closed or deeper end of the groove at one side of the disk is diametricallv opposite the corresponding end of the groove at the other side of the disk, and the open or opposite ends of the two grooves are similarly disposed. To one side of the open end of each groove 28, in the arcof a similar I circle, there is provided in the disk face a port or recess 30 equal in depth to the length of pins 29.

As above stated, disks or looking

elements

20 and 21 are apertured at 22 and 23 to receive the ends of rod or axle 24. Rod 24 is threaded at each end 31 to receive winged nuts 32 secured to disks 20 by short screws as shown, passing through the wings of said nuts. Slide elements or casings 33 and 34: have a sliding fiton rod 2 1 and are secured to hinge elements 21 by screws 35 passing through wings 36 at the outer ends of the tubes.

Between end portion 37 of tube 33 and shoulder 38 forming an integral part of said tube, there is provided the finger-grip 39 having the annular extension 40 loosely mounted on tube 33. Finger-grip 41 is rigidly connected to the outer end of enlarge d portion or casing 42 of tube 34. Within casing 42 there is provided the light spring 43 adapted to bear at one end against end portion 37 of tube 33 and at the other end against the outer end of casing 42. Casing 42 is provided at its bottom with the longitudinally extending slot 44 into which finger-grip 39 passes when grips 39 and 41 are pressed toward each othe against the tension of spring 43. One side of casing 42 is also cut away and has a tapered contour as shown at 4.5 in Fig. 3, for a purpose to be described. As means for limiting the manually operative movement of a slide element 1 provide rod 24 with the shoulder 48 for contact with a slide element.

The top 45 of the stand comprises preferably a strong piece of washable cloth or any suitable flexible fabric and may be detachably secured to tops 46 of the frame by spring fasteners, as shown, or in any suitable way. When the stand is in the folded or closed position cover 45 will hang between the side extensions as shown in Fig. 2. Rods 47 serve as braces for

frames

16 and 17 and also to maintain top 45 between the frames when the stand is closed and in an inclined position. They may also serve as towel supports.

When the stand is in the closed position pins 29 of hinge elements 21 engage in the deeper ends of slots 28 in hinge elements 20. As the stand is opened pins 29 emerge from inclined grooves 28 and each pair of cooperating

hinge elements

20 and 21 is forced apart. hen the frames reach the relative positions shown in Fig. 1, pins 29 and recesses 30 have come opposite to each other, and the two sets of hinge elements are automatically forced together by the pressure of spring 43 against

slide elements

33 and 34, pins 29 passing into recesses 30. The stand is thus automatically locked in the open position.

When it is desired to close the stand, finger-

grips

39 and 41 are pressed toward each other, moving

tubes

33 and 34 with disks 21 inwardly, the inner end of tube or member 33 sliding within casing 42 of member 34. This causes the withdrawal of pins 29 from recesses 30 and

permits sections

16 and 17 to be moved into the closed position; it being understood that in the movement of the two frame sections in either direction a disk 20 turns with rod and a cooperating disk 21 turns with its

slide element

33 or 34 as the case may be, upon rod 24 at one side of the stand, while at the opposite side of the stand the movement of disk 21 with the rod-inclosing slide element is with and the movement of disk 20 in reverse direction to the movement of rod 24. As frames 16 and 17 are pushed toward each other into the closed position the finger grips may be released. Spring 43 then moves

members

33 and 34 outwardly and pins 29 engage in the open ends of grooves 28 and pass through said grooves to the deeper ends of the same, at which time the opposed faces of each pair of

disks

20 and 21 come together and corresponding frame sections of the two frames are brought together as shown in F 3.

As additional means for maintaining the stand locked in the open position, fingergrip 39 may be given a quarter turn. This causes it to'bind against the inclined endportion 45 of casing 42 and the stand is then further locked in. the open position and cannot be closed until grip 39 is turned back to its normal position in line with slot 44 in casing 42. In the event of wear between grip 39 and inclined portion 45 of casing 42, nuts 32 on threaded ends 31 of rod 24 may be tightened to cause the correct adjustment between the grip 39 and easing In the use of my device the baby will be laid upon top 45 in position parallel with frame extensions 46. The mother or nurse mayibe seated with the knees beneath extensions 46 in such position as easily to reach the baby. The slight sag or dip of the fabric top 45 will serve effectually to prevent the baby from rolling off of the stand and this sag or dip will be further increased by the resiliency of

frames

16 and 17 and any elasticity of the fabric top. It will be understood that all danger of injury from the bumping of the childs head will be eliminated since the only possible Contact of the head with the stand will be against support 45 slung between top extensions .46 of

resilient frames

16 and 17.

In the event of a failure to open the stand to its fullest extent, at which point it looks automatically, the first weight brought to bear upon top 45 will immediately open the stand to its fullest extent and cause its automatic locking in such position. It will also be understood that the base extensions 47 are of such a wide spread and present so long a bearing surface as to practically eliminate any danger of the stand toppling over.
