DISPLAY BOX I Filed Sept. 26, 1936 .5 I INVENTOR '7 I 7 Jrome v/Vat Gross BY TORNEY Fatented Aug. 9, 1938 UNITED STATES PATENT ornca Jerome Shiiiman' and Harry Gross,

hpplication September 26, 1986; Serial No. masses 5 Claims. (01. 10-123 This invention relates to an improvement in boxes, jewelry cases or other receptacles, and

more particularly to the hinge structure thereof.

At the present time, boxes of this character are often made of hard plastic materials. such as the phenolic substance commonly referred to as "Bakelite", and of other similar materials. Due to the lack of resiliency in these materials, the

conventional methods of attaching a hinge to connect the cover to the body of the box, are often impracticable because of the possibility of cracking or breaking the box when" rivets or the like are employed. Additionally, it is highly desirable, in boxes of this kind, to present a smooth. attractive exterior .on the box, and the appearance therepf is often detracted from by the exposed heads of rivets or other similar hinge-attaching means.

The primary object therefore, of this invention is to provide a hinge structure which can be easily attached to the box body and coverwithout the possibility of damaging or breaking the box or cover; and dispensing with the use of rivets or other means which penetrate the box and are exposed'ou the exterior thereof.

A iurther=obiect of the invention is to provide a hinge structureso positioned at the junction provided with a of the box body and cover that it is relatively indiscernible whether the box is open or closed thereby greatly improving the exterior appearanceoi the box and providing a more satisfactory fit between the box body and its cover.

. In the accompanying drawing, wherein an -emv Fig. 1 is a vertical sectional view through a box provided with the improved hinge structure, the view being taken on the line i-l -oi Fig. 2, looking in the direction of the arrows: Fi'g. Z-is avertical sectional view through the same at'right angles to I the viewof Fig.1; Fig. 3 is a sectional view taken as in Fig. l, with the cover of the box inopen position; Fig.4 is.a sectional viewon the line 4-4 of Fig. 2, looking in the direction of the arrows; Fig. 5 is a sectional viewsimilar to that of Fig. 4,,with the cover of the box in 'open position: and Fig. 6 is a perspective view of the ,hinge. T In the drawingi indicates ing chamber of the box. The same may be of any particular ornamental form or shape and has a bottom! from which extends the upstand- "ing circumferential wall I. "I'he portion oi. the wall at the rear of the-box, designated at 4, is downwardly extending recess o'r slot 5 for the reception of'the leaf ll of thehinge as' will bis hereinafter pointed out." The cover as shown at O and the edge Thehinge is composed ner to receive-the hinge pin ofsaid ends engaging over the body or containagainst leaf i i v recess or slot 1 which receives the leai ll of the hinge. The rear wall 4 of the box has its upper end provided with a rounded or curved rib or bead portion of the cover 8 normally overlying this rounded portion 8' on the body of. the box is complementarily curved as shown at 9 to closely fit over and conform to said bead.

shown in detail in Fig. 6 and is of'the two leaves l and Ii rolled or curled as indicated at I! in the conventional man- [3. The leafl l,which is that entering into the slot 1 in cover 6-is ofifset at 14. Said leaf is also split at the several points indicated at IE to provide spring tongues l6" and i1 being oii'set as shown at It, or

.I- and frictionally gripping the sidewalls thereof. In order to retain the leaf l I in slot 1, the tongues l6 and il thereon are roughened or provided with barbs or sharp projecgtions i9 acting as prongs.

These sharp projec tions impinge against the sidewalls of the slot I by pressure of the spring tongues l6 and I1 and grip the same so that the leaf ll will-be firmly held within the slot 1 after it has been thrust therein. The other leaf, that shown at Ill, is similarly split at 20 and has the split portlons constituting spring tongues 2| and 22 which are spread apart and provided with sharp points or barbs 28 for engagement with the side walls of the slot 5. g

with the arrangement shown, the hinge is very easily fitted in place by inserting the leaf it in slot and forcing the same therein. The spring-. iness in the tongues 2i and 22 aided by the contact of prongs or barbs 23 with the walls of the slotsecurely holdsthe leaf it within the slot. Similarly leaf ll projects into slot 'I in the cover, and its tongues it and IT, having their barbed surfaces is engaging the walls of said slot securely holds the leaf withinthe slot. A curved spring 25, formedwith hooked ends 26. has one a bar '21 formed on the leaf ii, the other hooked end engaging over place Within the the edge 28 on the'leaf It. This spring serves:

to hold the cover of the box in either of the closed or open positions asshown in Fig. 3.

The bead I formed on the top edge of the wall portion 4 is cut away slot I to form a shoulder 30 which acts as a stop which the offset portion 14 or the hinge along its inner edge above impingeswhen the cover ofthe box is in its raised position to thereby restrict the opening movement of the cover.- This offset portion H of the hinge leaf Ii enables the use of the part 3| of the bead 8 directly behind the hinge, said part 3i co-operating with the complementary recess to practically close-the space between the cover and the body of the box at the hinge, leaving only the relatively small clearance space 32 through which little, if any part of the hinge, is visible from the outside of the box when the cover is in bothits open and closed positions.

As will be seen in Figs. 2 and 6, the hinge is formed with projecting ends 33 surrounding the hinge pin l3, said ends seating in the pockets 34 formed at the opposite ends of slot 5 at the top' thereof. The retention of these ends 33 in said pockets prevents any forward shifting movement of the cover with respect to the box body and thereby holds the cover in alignment therewith.

Through the arrangement disclosed, a satisfactory hinge structure is provided which may be easily attached to the body of the box and its cover, by forcing the two leaves of the spring into the slots in the cover and body respectively. The spring tongues on said leaves, formed by splitting the leaves and spreading the tongues, or

' offsetting one tongue from that adjacent to it as shown in'Fig. 6, resiliently engage the walls of the slot with their roughened or pronged surfaces in impingement therewith. The tongues are thereby firmly held in the slots of the cover and box body and the hinge attached in position without piercing the body of the box or cover. Accordingly, the exterior appearance of the box is smooth and unbroken by any projections such as rivet heads or the like. Also, the manner in which the cover is fitted and co-operates with the offset portion of the hinge, produces a cover fitment wherein the hinge is rendered substantiallyinvisible from the exterior of the box. Since'such boxes are lined or internally padded, which lining extends over and conceals the 'hinge on the interior of the box, the entire hinge is completely 'concealedin the finished box and the appearance of the box is greatly enhanced.

What we claim is: a i 1. A box or similar receptacle having a 'body portion and'a cover, a hinge connecting the body portion'and the cover,.the body portion and cover each having a slotin itsb'ack wall extending inwardly from the edge thereof, the hinge having pivotally connected leaves, one of each of said leaves extending into each of the slots, each leaf I edges of the body portion and cover, the hinge 7 having a pair of pivotally connected leaves, one

of said leaves' extending into the slot in the body portion and the other leaf extending into the slot in the cover, each leaf being split inwardly from one of its edges to divide it into several spring tongues, the splits in the leaves extending from one end of the leaves toward the point of pivotal connection of the leaves said tongues being spaced apart to cause their faces to frictionally .engage against the interior wall surfaces only of the slot in which they are disposed to thereby hold the leaf within the slot.

' 3. A box or similar article having a body portionand a cover, a hinge connecting the body portion with the cover, the body portion and cover each having a slot in its back wall extending inwardly from the edge thereof the hinge having pivotally connected leaves, each of said leaves extending into each of the slots, each leaf being formed with resilient tongues spaced from one another and disposed within the slot and having their faces only frictionally engaging the opposed faces of the walls thereof to thereby anchor the leaf within the slot, said wall-engaging faces on said tongues being provided with gripping projections.

4. A hinge structure for attachment to boxes or like'receptacles composed of plastic or similar hard materials, consisting of a box provided with an upstanding rear wall formed with a slot extending downwardly from its upper edge, said tongue being provided with a roughened gripping surface for impingement against a wall surface within the slot. I

5. A box or similar receptacle having a body portion and cover hinged thereto, the body portionandcover being provided with overlying slots in their rear walls, the hinge having pivotally connected leaves extending into the slots, the leaf extending into the, slot in the cover having an offset portion entering said slot, tongues on the leavesfor frictionally engaging the wall surfaces of the slots to thereby hold the leaves within the slots, a rounded bead extending along the top of the rear wall of the body of the box, said bead having a shoulder facing the insideof the box and against which a part of the offset leaf of the hinge may impinge when the cover of the box is in open position.
