Our present invention relates to hinge constructions particularly suited for the deck lids oi compartments, such as the trunk compartments of automobiles. 'The primary object 01' the prescut-invention is to provide a sturdy'hinge for the deck lid of a compartment, which hinge will have various advantages as will presently appear.

One object 01 the present invention is to proone arm or to the .deck lid and forming the operating lever of thetoggle, and the other armof which is surrounded by a spring adapted to retain the deck lid in closed position, to aid in raising the deck lid from a partially open position to raised position and to resist free closing 01' the deck lid in order that accidental injury to a persons hands or fingers might be avoided.

Another object of the present invention is to provide a toggle hinge construction having a spring aiding in the operation or the toggle, such spring being positioned about an arm of the toggle and bearing against a shoulder on the arm and a fixed abutment.

Another object of the invention is to provide a fixed abutment for the spring of a spring toggle by means of a guide member passing through a slot in an arm 01- the toggle about which the spring is positioned, so that as the joint of the toggle approaches a straight line between the pivotal supports for the ends of the arms of the toggle, the spring will be compressed and vretained in compressed position to aid in retaining the deck lid in closed position, to aid in raising the deck lid from a partially opened position to raised position, and to resist closing of the deck lid.

Anotherobject of the present invention is to provide a toggle arm for the construction outlined above which is relatively simple to manufacture and sturdy in construction, said toggle arm comprising complementary longitudinal halves each of which is bent laterally adjacent the Joint of the toggle to form shoulders against which the compression spring 'maybear, and each of which may be formed at its free end to provide one portion of complementary snap-engaging means for holding the deck lid in raised position.

Another object of the present invention is to provide relatively simple but effective complementary snap-engaging means associated with an arm of a spring-aided toggle hinge comprising protrusions on the arm of the toggle and a spring clip adapted to engage said protrusions whenthe deck lid is in raised position, which snap-engaging means may be readily disassoci- 1 ated by the application 01' downward pressure to the deck 11d.

These and other objects and advantages oithe as to be capable of passing around the the edge of the opening in which struction of the present invention will be more fully apparent from a study of the following specification and accompanying drawings wherein like numerals refer to like parts throughout.

In the drawings,

Fig. l is a sectional view through a portion of I the trunk compartment of an automobile and of the deck lid therefor and showing the hinge conpresent invention in closed'position; s

Fig. 2 is a view similar to Fig. l but showing the deck lid in raised position and the complementary snap-engaging means engaged to hold the deck lid in raised position;

Fig. 3 is a detail view taken substantially along line 3-3 01' Fig. 2, showing the construction of the complete hinge;

Fig. 4 is a vertical section on an enlarged scale of the snap-engaging means taken substantially along line 44 of Fig. 2; and,

Fig. 5 is a section on an enlarged scale of the toggle Joint taken substantially along line 5-5 of Fig. 1. f

The present invention is shown as associated with the rear compartment of an automobile having a rear wall l0 in which is provided an opening adapted to be closed by a deck lid ll, the'edge of the deck lid resting upon a resilient strip l2 encircling the opening. The upper wall of the compartment closed by the deck lid is provided with a bracing channel member IS-having an overhanging rear end It adjacent the upper edge of the opening closed by the deck lid ll. At the rear extremity of the channel member l5 there is provided a bolt H which extends between the walls of the channel member and provides a fixed pivot for one arm hinge construction. The arm tached by joint member I9 to the other arm 20 of the toggle, and the arm is provided with an integral extension 2| attached to the deck lid and forming-the operating lever of the toggle. The extension 2| is reversely bent in U-sliape so overhan ing rear end It of the channel member l5 and the rubber strip I2 is positioned. As seen in Fig. 3, it is to be appreciated that the extension 2! is formed as a yoke member so as to have both ends there- IB is pivotally atof forming arms l8 of a pair of toggle hinges,

thus imparting rigidity to the entire deck lid construction. A rubbe'r bumper 22 may be provided on the surface of the extension 2| adjacent the joint member I! so as to engage the overhanging end It and prevent metal to metal contact of moving parts when the deck lid is raised.

Each of the arms 20 preferably comprises come plementary right and left stampings welded together' throughout the greater portion of their length so as to form a fairly rigid construction.

l8 of a toggle Each complementary half is preferably bent laterally near one end so as to form a pair of shoulders 25 adjacent the toggle joint, and then bent longitudinally again to form a clevis adapted to have the toggle joint member I9 pass therethrough to join arm I8 to arm 20. Each of the complementary halves is likewise provided with a protrustion 30 adjacent the opposite end thereof, the pair of protrusions being opposite each other to form a rounded bulge near the end of the toggle arm 20. A slot 3| extends longitudinally of the toggle arm 20 from a point near the protrusions 30 toward the joint Of"th6"b0l818, and a fixed guide member 32 mounted in the flanges of member l passes through the slot 3| to guide the arm as it is moved by the action of the toggle.

A spring 35 is maintained in position about the arm 20, one end of the spring bearing against the shoulders and the other end of the spring bearing against the guide member 32. The spring is compressed to its greatest extent when the distance between the shoulders 25 and the guide member 32 is shortest, which would be when the toggle joint member the fixed pivot l1 and the guide member 32. The arms I8 and 20 are so related to the shape of the extension 2| and the deck lid II that the deck lid is almost in closed position when the spring 35 is compressed to the greatest extent,

and the toggle joint member IE will have passed beyond the line between fixed pivot l1 and guide member 32 when the deck lid is fully closed so that the spring resists opening of the deck lid and holds the same firmly against the rubberous strip I2. However, as soon as the deck lid has been opened slightly against the further compression of spring 35 the joint member i9 will pass beyond the line between the fixed pivot I! and the guide member 32 in the opposite direction and spring 35 will. aid in raising the deck lid. Preferably, sufiicient strength is provided in spring 35 and the spring is so proportioned as to aid in holding the deck lid in raised position. Likewise, it may be seen that the spring resists closing of the deck lid increasingly as the deck lid moves toward an almost closed position so as to act as a safetydevice-preventing accidental smashing of fingers, etc.

In order to hold the deck lid in completely raised position the e is preferably provided snap-engaging means which may be disengaged by a direct pull on the deck lid when in raised position. Such means comprise the protrusions 30 and a spring clip mounted upon the'guide member 32. The spring clip is preferably U- shaped, with the bight 4| thereof extending through the slot 3| so as to maintain the legs 42 of the U-shaped clip in alignment with the longitudinal dimensions of toggle arm 20, and the legs 42 of the U-shaped clip member are preferably looped in shape so as to engage over the protrusions 30. The member 40 as shown in the drawings is formed by bending andshaping a continuous piece of wire so as to provide each leg of the U-shaped member with a portion adapted to embrace a reduced portion ofthe guide member 32 which serves to hold the member 40 against lateral displacement. Other forms 01' spring clip engaging members may be substituted, the present form being one found to be easily manufactured and assembled.

Having described the preferred embodiment of our'invention, it should be apparent to those skilled in the art that the same permits of modi- IQ is in line with fications in detail and arrangement. All such modifications as come within the scope of the following claims are considered to be a part of our invention.
