17 Claims.

This invention relates to hinges particularly adapted for pivotally connecting together aswinging closure and a fixed body or support, the hinge of the present invention being especially useful in connection with swinging doors or lids of vehicle bodies, such as trunk, hood or deck lids of motor vehicles.

An object of the invention is to provide a hinge for an upwardly swinging closure or lid which is provided with improved, relatively simple and efficient means for automatically locking the lid in a raised position, the locking means being operated simply by manipulating the lid in raising and lowering the same.

A further object is to provide a hinge comprising a fixed or stationary hinge member and a movable hinge member pivoted together, the

members being provided with cooperating locking and unlocking means including a rotatable device, such as a wheel with equally spaced teeth or projections, effective in cooperation to rotate the wheel step by step into successive positions, either for looking or unlocking the parts, when the lid is raised to a given position, then lowered to locked position and thereafter raised and lowered toward closed position.

Other objects of this invention will appear in the following description and appended claims, reference being had to the accompanying drawing forming a part of this specification wherein like reference characters designate corresponding partsin the several views.

Fig. 1 is a fragmentary longitudinal section of a portion 'of an automobile body illustrating a lid or closure hinged to the body by means of a hinge device constructed in accordance with the present invention.

Fig. 2 is a view somewhat similar. to Fig. 1 but illustrating the lid in raised locked position. 40 Fig. 3 is a somewhat similar view illustrating the lid in an elevated position preparatory to lowering the same into locked position,

Fig. 4 is a similar view illustrating the lid raised from its locked position preparatory to 45 lowering the same into the position illustrated in Fig. 1.

Fig. 5 is a vertical sectional view taken along the line 55 of Fig. l. I

Before explaining in detail the present inven- 50 tion it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawing, since the invention is capable of other embodiments and 55 of being practiced or carried out in various ways.

Also it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation, and it is not intended to limit the invention claimed herein beyond the requirements of the prior art. 5 In the drawing there is illustrated, by way of example, a hinge embodying the present invention as applied to a swinging closure, such as the deck lid or trunk lid of an automobile body, the hinge comprising two hinge members pivl0 oted together one thereof secured to a permanent or fixed part of the body and the other secured to the swinging lid or closure. It will be understood that the hinge may be utilized in connection with other closures such, for exam- 15 ple, as the swinging hood lid of a vehicle body.

In the illustrated example the rear metal panel 10 of the body forming a deck, trunk or other compartment thereof is provided with an opening which is adapted to be closed by means of a 20 swinging lid I I. This lid may comprise a stamped metal outer panel and an inner reinforcing panel I 2 secured thereto by spot welding. The upper edge of the outer panel H terminates in the present instance in a transverse marginal flange 25 or lip l3 cooperable, when the lid is closed, with a sealing strip M of rubber or other suitable material retained within a channel l5 formed along the adjacent edge of the permanent body panel l0. comprises a fixed hinge member l6 secured to the body panel I!) and a swinging hinge member l1 fixed, for example, to the side edge of the lid ll adjacent the top thereof. The fixed hinge member 16 comprises a pair of plates "5a and l8b spot welded or otherwise secured together face to face, as illustrated in Fig. 5, these plates having oppositely turned flanges I60 and "id which are spot welded to the underface of the panel Ill. The movable hinge member I! also I comprises a pair of metal plates which are spot welded together face to face and formed with oppositely turned flanges llc which are spot welded to the upper edge of the inner panel I2 of the lid. The plates forming the hinge member I! are offset adjacent their forward ends to provide spaced extensions Fla and Nb straddling the'hinge member 16 as illustrated in Fig. 5. The extensions Ha and "b of the hinge member I1 are pivoted to the fixed hinge member l6 through the medium oii'a pivot pin la in the form of a rivet extending through the parts and headed over at opposite ends.

Also housed between the bifurcated ends I la and 11b of the hinge member I! and arranged The hinge in the present instance 30 v below the hinge member It is a locking device I! which in the present instance is in the form of a freely rotatable toothed member or starshaped wheel. The toothed member is is pivoted to the spaced sides lid and I'll) by means of a rivet pin III. This device is substantially star-shaped to provide three equally spaced teeth or projections "a, lib and I90 which are joined by inwardly curved arcuate edge portions 2i shaped'to correspond to the curvature of the lower curved edge 22 of the hinge member I}.

Thus, when the lid II is fully closed, as illustrated in Fig. 1, one of the concave edgeportions II will fit smoothly against the lower edge l! of the hinge member I. thereby positioning the wheel I 8 so that when the lid is raised the wheel I! and one 01. its teeth will travel into the proper position with relation to the cooperating locking portions of the hinge member I.

The hinge member It is provided with a locking and unlocking portion cooperating with the teeth or projections I90, lib and lie and adapted to control the position of the wheel I! so that the hinge members may be automatically locked together and also unlocked by simply manipulating the lid II. In the present instance the hinge member I8 is provided with an inclined cam forming edge 23 terminating at the top thereof in a recess or notch 24. The hinge member I6 is also provided with a locking recess or notch 25 adjacent the base 22 of the hinge member. Rearwardly of the recess 24 the hinge member It is formed with an overhanging portion provided with a cam-like recess or notch 26 and intermediate the cam portion 23 and the recess 25 there is provided a recess or notch 21.

It will be seen that when the lid II is raised from the closed position shown in Fig. 1 to the position shown in Fig. 3 the wheel I! will be carried rearwardly with the hinge member I1, and the tooth Ita, as illustrated in dotted lines in Fig. 3, will engage and travel over the cam edge 23 until it is seated in the recess or notch 24, this position of the wheel I! being illustrated in full lines in Fig. '3. At this point the lid will have been raised to its fullest extent and upward movement thereof will be limited by the abutment of the tooth Isa against the base of the recess 24. During this step in the operation it will be seen that the wheel I 9 will have been partially rotated in a counter-clockwise direction from the dotted line position of Fig. 3 to the full line position thereof, thereby causing the tooth Ila to clear and pass around the corner 22a so as to position it opposite the locking recess 25. Hence, when the lid is lowered from the position of Fig. 3 to the position of Fig. 2 the tooth He will move into the recess 25' and will be anchored against the base thereof, thereby locking the hinge members It and I1 together and maintaining the lid in raised position as illustrated. As the wheel moves downward from the position of Fig. 3 to the position of Fig. 2 the nose of the projection llc rides over the cam edge Ila into the recess 15 which effects a partial counter-clockwise rotation of the wheel causing the end of the projection Ila to pass the corner a and face the recess 2'.

when it is desired to unlock the lid and lower it to its closed position it is merely necessary to raise the lid again from the position of Fig. 2 to the position of Fig. 4. In this operation the hinge member I! is elevated somewhat thereby carrying the wheel is upwards. Since in the locked position of the parts the tooth Ila has been rotated to a position lacing the cam-like recess 28 it will, therefore, be seen that by raising the lid from the position of Fig. 2 to the position of Fig. 4 the nose of the tooth l9a will move into the recess 26 and due to the inclined cam edge a thereof engaging the tooth Isa the wheel I! will again be slightly rotated in a counterclockwise direction. Hence, in this step of the operation the tooth I90 will be rotated upwardly away from the locking recess 25, ample clearance therefor being provided by the recess 21. With the parts in the position of Fig. 4 the hinge members will be unlocked and the lid may then be lowered to its closed position since the wheel I! will be carried downwardly free of locking engagement with the locking recess 25, the projection or tooth l9c riding over the jutting portion 220. which efl'ects a further counter-clockwise rotation of the wheel so that when the lid is closed the parts will again assume a position as illustrated in Fig. 1.
