CONCEALED HINGE Filed Nov. 2, 1938 IN VEN TOR.

M/CHA E L I .7. E cor/amass Patented Oct. 29, 1940 UNITED STATES PATENT orrice 6 Claims.

This invention relates to concealed hinges. More particularly, it relates to an improved, concealed hinge for use in automobiles and like vehicles, said hinge being adapted to be concealed and attached in a door and car frame.

The present invention has for an objectto pro- Vide a concealed hinge which is easily made but preferably from any suitable sheet metal and which is of superior mechanical features than any heretofore used.

Another object of the present invention is to provide a hinge wherein the sides thereof are readily attachable to a door and frame of a car.

One other object of the present invention is to provide a concealed hinge for use in automotive vehicles and the like, adapted to eliminate rattling of the doors in which said hinge is used.

Still another object of the present invention is to provide a hinge having a movable portion disengageable from a main portion of said hinge to permit easy removal of a door froma frame when said hinge is used.

A further and more specific object of the present invention is to provide a hinge having a fixed portion provided with a guideway adapted to retain a guide connected with a movable portion of the hinge, said guide being also adapted to check the opening of a door to which it is connected.

Another object of .the present invention is to provide a concealed hinge in connection with a door and frame adapted to be disengaged to permit removal of the door from the frame without the removal of screws and the like as used heretofore in hinges.

Other objects and features will become apparent upon reading the following detailed description of the embodiment of the present invention.

The invention generally consists in the features of novelty appearing in the construction, arrangement and cooperation of the several parts hereinafter fully described and is taken in connection with the accompanying drawing, in which Fig. 1 is a vertical front view of a preferred embodiment as mountedin a frame and door frag: mentally shown.

Fig. 2 is a vertical sectional view of my embodiment.

Fig. 3 is a plan View taken on line 3-3 looking in the direction of the arrows in Fig. 2, and

Fig. 4 is a plan view of Fig. 1.

Fig. 5 is a perspective view of the stationary part of my embodiment.

Referring now to the drawing, in which like reference characters designate like parts throughout, aframe section A of an automobile or other vehicle is recessed to accommodate thenon-movable portion of the device as shown in Figs. 1 and 4. Said portion is made of any suitable material such as sheet metal blanks and is preferably of rectangular shape with a front and two opposed side walls as shown. The walls 50, II and I2 respectively, of said portion are provided with a plurality of openings [3, Hi and 15 respectively, into which fit screw members (not shown), for fixing the portion to frame section A. Said portion furthermore, is provided with a pair of spaced, parallel, horizontal plates it and I'L'respectively, fixedto the vertical walls as shown in Fig. 2, being joined thereto and forming a part thereof, by any suitable means well known in the art. It is to be noted that the front wall Id at its upper portion has an opening l8, continuing along a reduced slot l9 and a wider continuing curved slot 28 in the upper horizontal plate. Furthermore, the front wall is provided with an opening 2| into which fits a screw or rivet member'22 forpivotally holding a safety catch E, while the upper horizontal plate has an opening 23 for a rivet member 24 retaining a check D. Said check D can be swung outwardly of the vertical front wall Ill and around the rivet as an axis and has upwardly ertending spacedlug ends 25 and 26, respectively adapted to fit into the corresponding opening 48 andbe retained therein by means of said catch E thus closing said opening.

Said lower horizontal plate I6 is provided with a curved slot 2'! and a slightly reduced curved guide slot 28 and 29. His to be noted that slot 21 is substantially of the same size as slot 2% and disposed directly beneath said latter slot for purposes hereinafter described in detail.

Adapted to coact with the non-movable section of the hinge above described and shown in the drawing, there is provided a movable hinge member GH having a plurality of vertical side walls 30 and 3|, respectively and a face wall 32 integral therewith as shown in the drawing. Said fitting into the space between thehorizontal par- 55 i allel plates and I1 and has an opening 34 for accommodating a pintle 35. It is to be noted that said pintle has a plurality of sections of different diameters along its length as shown in Figs. 1 and 2. ,Section 36 is the top portion of the pintle adapted to fit in slot and slide therein, while section 31 is reduced and fits in the space intermediate the horizontal plate members. Section 38 of the pintle on the other hand, is of substantially the same diameter as section 36 and is fitted or swaged into position in opening 34 of the hinge member G--H. The lowermost portion of the pintle has a relatively wider section 39 adapted to slide in slot 21 in the lower hori- N zontal plate as shown in Fig. 3 of the drawing. It is to be noted from the above description of the pintle that it is fitted at right angles to the longitudinal axis of member G-H. Furthermore,

each section of the pintle has a particular funcwith the wider curved slot of the other member, a

tion in the operation of the hinge member.

In order to limit the outward and inward movement of said hinge member G-H, there is provided a guide member 43 adapted to fit in the recess 4| provided therefor, on the curved arm of member G-I-I. Said member has a recessed portion 42 adapted to travel in slot 28-29 in lower plate I6 as shown in Fig. 4. Furthermore, guide member 40 is fitted into slot 28 and 29 by initially placing same in the reduced portion 28 of said slot. It is to be noted that once the movable hinge member G-H is mounted, it can be slidin or out as desired without coming apart from the fixed non-movable portion mounted in section A, as shown in Figs. 1 and 4 of the drawing.

In order to assemble and operate the device as disclosed herein, the pivoted safety catch member E is swung about its pivot so that the free end thereof is raised to form contact with the upwardly extending spaced lugs or ends 25 and 26 of check D. Said check D is swung outwardly on its pivot to permit the insertion of the pintle into slot l920 and the insertion of guide into slot 28-29. This having been done the check D is closed and engaged with safety check member E, as shown in Figs. 1 and 2. It is to be noted that the space between the two horizontal plates is of sufficient depth to permit the slight raising of hinge member G--H for proper insertion into the slots above indicated without permitting any unnecessary rattling.

In the operation of the hinge above described, the movable section G-H being mounted onto a door may be moved in and out of the fixed section C. In such cases, the pintle 35 having parts 36, 31, 38 and 39 mounted on curved arm GH moves in slots 20 and 21, while guide member 40 moves in slot 28, 29 and retains the movable section of the hinge in operable position without becoming separated from fixed section C. The device as described hereinmaybepreferablymade of sheet metal blanks of any desirable shape and then bent to form the embodiment as shown in the drawing herein.

The device as described is adapted for either straight line or curved doors of automobiles or other vehicles or even building doors. The device can be easily mounted and the width of the fixed portion can be varied to suit the particular type of application. Also, the device permits of a snug fit in the door frame, while the removable portion is fixed to the door by means of rivets or like means.

, It is to be noted that the, embodiment as disclosed herein in connection with the accompanying drawing, is an improvement on the inventions disclosed in my patents numbered 1,633,480 and 1,646,644 granted June 21, 1927, and Oct. 25, 1927, respectively.

While one preferred form of my invention has been described in connection with the accompanying' drawing, it is understood that various modifications as to form, material, arrangement and use of materials may be made without departing from the spirit and scope of my invention.
