1 Claim.

This invention relates to an improved stop for a door and more particularly to a stop operatively associated with the door hinge unit.

An object of the invention is the provision of an improved stop for yieldably opposing movement of the door from an open to a closed position, and to provide a stop of the above type operatively associated with the door hinge unit.

Another object of the invention is to provide a stop which is fixedly carried by one hinge part and engages another such part to yieldably oppose relative movements of the parts, whereby the door is yieldably retained in an open position.

A still further object of the invention is to provide a stop which is simple in construction and which lends itself to economies in manufacture and assembly,

Other objects and advantages of the invention will be more apparent from the accompanying drawing, in which:

Fig. 1 is a fragmentary side elevational view of a vehicle body including a door having the invention applied thereto.

Fig. 2 is a fragmentary transverse sectional view taken on line 22 of Fig. l.

Fig. 3 is a fragmentary vertical sectional view taken on line 3-3 of Fig. 2.

Fig. 4 is a view in perspective of the stop.

The invention is illustrated and described in connection with a vehicle body, generally indicated by the numeral l0, having a door I I hinged thereto for swinging movement. The body I is of the all metal type and includes a hollow support or pillar-forming portion l2, the jamb of which has an opening therein. The door hinge unit includes a support part, generally indicated at I3, having oppositely extending flanges I 4 abutting the door jamb and secured to the pillar l2 by screws l5. Integral with the flanges I4 is a channel-shaped part projecting through the opening in the jamb having upper and lower walls l6 and 11, respectively, and a connecting web IS, the wall l6 having an opening l9 therein. The companion hinge part comprises an arm 20 secured to the door H by screws 2|, and having a portion thereof projecting through the opening in the jamb, this projecting portion having an eye in the end thereof which registers with openings 22 and 23 in the walls and I1, respectively, for receiving a hinge pintle 24 having a threaded end 25. To increase the bearing surface for the pintle 24 the metal adjacent the openings 22 and 23 is deflected outwardly relative to the channel to form bosses 26 and 21, respectively.

In conjunction with the hinge unit I have provided a stop operable to yieldably retain the door in open position. As herein illustrated, the stop consists of an arm 23 secured to the hinge part l3 by the pintle 24, the arm 28 having an opening 29 therein receiving the pintle 2t and being disposed between the boss 26 and the head of the pintle 24. The arm 28 projects into the path of movement of the hinge arm 20, resulting from opening and closing movement of the door II, and has a downwardly deflected end portion 30 which projects through the opening [9 in the wall I 6 and provided with an arcuate contour for engagement with the upper edge portion of the arm 28, as more particularly shown in Fig. 3. The end portion 39 includes spaced vertically disposed prongs 3| engageable with the wall bounding the opening Hi to retain the arm 28 against undesired swinging movement when the deflected portion engages with the hinge arm 20.

In operation, as the door H is moved from closed to open position, the arm 28 engages the hinge arm 20 and acts as a stop or check for the door. However, upon the application of a force the arm 28 will be sprung upwardly over the hinge arm 20 to accommodate complete opening of the door. Similarly, the arm 28 will engage with the hinge arm 20 to act as a stop against closing movement of the door. The degree of opposition exerted by the stop to movement of the door can be varied by varying the spring characteristics of the arm 28.

I claim:

In a door hinge unit including a hinge arm adapted to be secured to the door and a support part adapted to be secured to the door support and including spaced walls receiving said arm, one of said walls having an opening therein, a pintle pivotally connecting said arm and said walls, and a spring arm secured to said support by said pintle having a part thereof extending through said opening, said part. including a bowed portion having an arcuately contoured surface engageable with said hinge arm for yieldably opposing pivotal movement of said hinge arm relative to said support and having a pair of spaced prongs cooperable with the wall bounding said opening to yieldingly limit swinging movement of said spring arm when the arcuate surface thereof engages said hinge arm as aforesaid, one of said prongs being engageable with an edge portion of said opening for opposing swinging of said spring arm during movement of said hinge arm in one direction and the other of said prongs being engageable with an opposite edge portion of said opening for opposing swinging of said spring arm during movement of said hinge arm in an opposite direction.
