Application 5 Claims.

My invention relates to hinge connections. 7

It is an object of my'invention to provide an improved hinge connection, or hinge, which lends itself to quantity production of some suitable plastic material, such as artificial resin, by a process of molding under pressure.

Tothis end, I provide a hinge member defining a bearing which is open at one side. In the constructional example which will first be described, this hinge member is subdivided into a pair of spaced-apart bearing members whose bearings are open at the lower side, and the two members are made integral with the rear wall of a box from whose ends they project inwardly. Between the inner ends of the two bearing members, I

insert a mating hinge member. which in integral with the lid of the box. The mating member is solid and has two pins projecting from itsends which are arranged to enter the open bearings from below. A locking member is connected to the hinge member which defines the bearing. In the said constructional example, the locking member is a portion of the rear wall 'whose sides are separated from the body of the wall by slots so that the locking member is a sort of tongue which is connected to the body of the wall at its root only and therefore possesses a certain degree of elasticity. The locking. member is urged toward the interior of the box by the mating member asthe pin, or pins,-on the mating member is moved into. the open bearing, or bearings, and locks the mating member by elastic reaction when its pin, or pins, is in the bearing, or bearings.

In the accompanying drawing, a box equipped with my hinge connection, and an independent hinge, are illustrated by way of example.

In the drawing Fig. 1 is a perspective illustration oi. the compleltle .box, with its lid closed, viewed from its rear wa Figs. 2 and 3 are sections, respectively, on the lines IIlI and III-lII in Fig. 1.

Fig. 4 isa plan view of the box, with its lid removed.

Fig. 5 is a plan 'view of the lid. I FIg. 6 is a vertical section of the hinge structure, drawn to a larger scale, showing the method of assembly.

Fig. 7 is a transverse section of the independent hinge. i

Referring to Figs. 1 to 6 of the drawing, U is a box body and D is the lid which is provided with a solid cylindrical hinge projection I2 in-.

tegral with the rearwall II or the lid in and" May 24, 1938, Serial No. 209.795 Germany June 3, 1937 moulded with pins I3 and I4 projecting from its ends, the free ends of the said pins being rounded as shown in Fig. 5. The rear wall I5 of the box U is provided with a pair of mating hinge members I6 and I! which are integral-with the said rear wall I5 and are adapted to receive the hinge projection I2 between them. The hinge members I6, I! are provided with slots or recesses I8 in their inner end walls, the said slots being open'at their lower ends (Figs. 2 and 6) and are adapted to receive'the pins I3 and I 4, the slots and pins being axially aligned so as to enable the lid D to swing about the axis of-the pins I3, I4. The hinge members I6, I1 and the cylindrical hinge projection I2 form together a substantially continuous cylinder when the'lid isinpbsition -on the box. I I

The lid is maintained in position on the box body by means of an elastic locking member 2| integral with the rear wall I5 of the box body, the said locking member comprising a resilient tongue formed by providing slots I 9, 26 in the said rear wall in proximity to the centre of the space between the inner ends of the hinge members I6, I'l, so that the member 2| is connected to the wall I5 at its base only, as indicated by the horizontal dotted line in Figs. 2 and 6.' The tongue 2| is suificiently resilient to enable it to. be forced inwardly towards the interior of the box body. The rear wall I5 of the box body is provided with a recess I 5' extending between the inner ends of the hinge members I6, I1, the bottom of said recess being substantially tangential with the cylindrical surfaces of the said hinge members, as shown in Fig. 4, the upper part of the tongue 2I being correspondingly thinned so that its rear face is substantially level with the bottom 'of the recess I5. The recess I5 extends downwardly from the-upper edge of the rear wall I5 of the box bodyvfor a suilicient distance to allow the hinge projection I2 to pass below the hinge members I6 and I! and to be moved up-.

wardly to bring the pins I3, I4 into engagement with the recesses I8.

A projection 2| is provided on the rear face of thetongue 2|, the said projection having bevelled edges and being provided at its upper end with .a cylindrical seating curved to the radius '01 the.

the projection II and the tongue is forced inwardly into the box body in the direction of the horizontal arrow (Fig. 6) until the rear face of the'projection 2| is level with-the bottom of the recess II, whereupon the hinge projection is moved upwardly in the recess IS in the direction of the vertical arrow shown in Fig. 6. n the pins II, It arriving at their final upper position in the recesses II, the tongue 2i snaps back into its normal position with the cylindrical seating ,at the upper end of the projection 2| below the hinge projection I2, thereby retaining the hinge projection in position with its pins l3, ll in engagement with the slots l8.

Referring now to Fig. '1, this hinge is equipped with

plates

22 and 23, with

holes

24 and 25, respectively, for attaching it to the lower part and the lid of a box, or to any other objects to be hinged together. Otherwise, this independent hinge is quite similar tothe hinge connection described with reference to Figs. 1 to 6, and does not require any further description.

It will be understood that the hinge connection whose members are integral with the parts to be connected, as described with reference to Figs. 1

to 6, and the independent hinge described with I reference to Fig. 7, have a wide range of usefulness.- The members, including the parts with which they are integral in certain cases, are made in a single operation with simple tools, for instance, dies without slides or other movable parts.

Obviously, there may be as many bearing and 'mating members as required with consideration of the length of the parts to be connected. Nor am I limited to the particular construction shown and described.

The operation of assembling the hinge is very simple and notwithstanding the connection is very reliable. The time required for assembling one of my novel hinges is but a small fraction of that required for assembling a hinge having the usual hinge pin. 1
