It will be appreciated that in the broad aspects of this invention the door check arm may be connected to any suitable part of a door member or its adjacent supporting member; and the retainer means may be. connected to or form a part I of either of such members.

For example, the retainer means may be formed in one of the butt plates of a' door hinge and the arm connected to the other butt plate of the hinge. -However,

"in the more limited aspects of the invention, as shown in the drawings, and more particularly in Figs. l-'7, wherein a preferred embodimentof the invention is illustrated, it will be seen that the door check device includes a rigid elongated arm l3 which has one end thereof pivotally connected to a vehicle door member l5 by means of a pivot pin or rivet ll andbracket I8. The

an opening 28 and the plate 21 is provided with.

an elongated opening 29 in which the arm I3 is movably positioned and supported. An enlarged substantially fiat head portion 3| is formed on the'inner end of the arm I3, and is disposed inwardly of the retaining plate 21 when the door check is installed on a vehicle as shown A rigid washer-like member. 33, having an bowed portions 49 engage a wall of the retainer plate opening 23 and the spring strip is compressed toward the arm so as to permit the bowed portions to pass through the retainer plate opening and releasably retain the door in its open position. As there are a plurality of bowed portions the door can be releasably retained in either its fully open position or in partially opened positions. By offsetting thespring strip 43 adjacent its outer end, it will be appreciated that the intermediate portion of the spring strip elongated central aperture 35, is sleeved on the arm I3 and abuts the enlarged arm head portion 3|. A cushioning element 31, which has anelongated central aperture 39, is sleeved on the arm 7 I3. and: abuts the rigid member 33. The cushioning element 3'! engages the inner face of the retaining plate 2! when the vehicle'door I5 is in its-fully opened position, as illustrated in Fig. 1, so as to limit the maximum extent of opening movement of the door.

The arm I3 is, as can be best seen in Fig. 7, channel shaped in cross section; that is the opposite longitudinal sides of the arm I3 are bent upwardly at 4!. The channel shaped arm construction permits the arm to be formed from relatively light gauge metal. An elongated leaf spring strip 43 is positioned in the channel portion of the arm I3, that is, the spring strip 43 is positioned on the upper face of. the arm I3 between the upwardly bent sides 4| thereof. The

spring strip 43 is downwardly offset at its outer end, as indicated at 45, so that the offset portion abuts the upper face of the arm I3. adjacent the extreme outer end thereof. The opposite; or inner end of the spring strip 43 extends through the cushioning element central opening 39, and

the rigid washer member central opening 35, so

as to be movably positioned and guided thereby.

Therefore, the portion of the spring strip between ber 33, such compression is possible. The spring offset portion 3-5 is provided, adjacent its outer end, with an aperture 41, and the rivet or pivot pin I! which connects the arm I3 to the door bracket I 8 also connects the outer end of the spring strip 43 to the arm I3. However, when the door check device is sent to an automobile manufacturer for installation, the outer end of the spring strip 43 need not be connected to the arm, as the spring strip will normally be retained on the arm by the frictional engagement of its inner end with the cushioning element 31 and the rigid washer member 33.

The spring strip 43 is provided adjacent the arm cushioning element 31, with a plurality of longitudinally spaced, outwardly bowed portions 48, which are adapted to engage a wall of the retainer plate opening 29 so as to aid in checking the opening movement of the door and so as to releasably retain the door in an open position. When the door is opened the. outwa y l a .t-ablike projecting will resiliently maintain the arm and strip in frictional engagement with the walls of the retainer plate opening 29 so that there will be no play between the arm I3 and the retainer plate 21, which would cause any rattling when the device is installed on a vehicle.

Thus, the door check device of this invention is constructed so that only a single leaf spring strip is employed and the spring strip has its inner end movably positioned and guided by the rigid washer-like. member 33, so that, no addie tional attaching means need be provided for securing the end of the spring strip to the arm.

By extending the end of the spring strip through the washer member 33, the outer end of the spring strip is prevented from moving laterally With respect to the arm but the spring strip can, when compressed, move longitudinally with respect to the washer member 33. Furthermore, with the construction of this invention, the annoyance of having the door check device rattle when installed in a vehicle, is completely eliminated by the resilient and frictional engagement of the spring strip and arm with the retaining plate opening walls, even when the'door is completely closed as illustrated in Fig. 2.

Referring now to the embodiment illustrated in Figs. 8 through I1, it will be seen that the arrangement of the parts is the sameas that previously described. In this embodiment, the door check arm I3 is not channel shaped, as in the previous embodiment, but is made out of a heavier gauge metal, so that no reinforcing upturned flanges are necessary. Also, in this embodiment, the retaining member 25" is different in construction than the member illustrated in the previous embodiment. In this embodiment, the inner wall of the retainer bracket a plate 53 secured to its inner face. The bracket 26' has an elongated central aperture 28', as previously described, and the outer plate 5| has portion over the aperture 28', reversely bent, as indicated at 55, around one side wall of the aperture 28', so as to reinforce the same. The inner plate 53, similarly, has a tablike projecting portion which is r-eversely bent at 51, in the opposite direction, so as to reinforce the opposite edge of the bracket aperture 28'. With this construction there is no need for a retainer plate, such as plate 2'! in the previous embodiment, and the retainer member 25' is exceptionally strong and durable and the danger of the wall, which defines the opening 28, break- .ing away or becoming damaged is materially Figs. 1-7, the door'check devices are identical in construction and in function, so that a further description of the function of the door check device illustrated in Figs. 8. through. 11 is not deemed necessary and likembodiment are designated by primed numbers corresponding to like numbersin :the' first embodiment.
