' This invention relates generally to devices for checkingopening movement of a hinged door, and more particularly to a device for checking the opening movement of a motor vehicle door and for releasably holding the door in an open position. I

It is an object of the present invention to provide a new and improved device for checking opening movement of a motor vehicle door and for also releasably holding the door in an open position.

Another object of the invention is to provide new and improved buffer means for retarding opening swinging movement of a motor vehicle door and for yieldingly holding the door in an open position.

A further object of the invention is to provide a device of the above mentioned character which is inexpensiveto manufacture but which is efiicient in operation.

Other objects of the invention will become apparent from the following detailed description taken in connect-ion with the accompanying drawings, in Which- Figure 1 is a fragmentary view in horizontal section of a vehicle body door frameand door and my improved door check and releasable holder associated therewith;

' Fig. 2 is a vertical sectional view partly in elevation of the structure shown in Fig. 1;

Fig. 3 is a view similar to Fig. 1 but with the door shown in an open position;

Fig. 4 is a view similar to Fig. 3 showing the door in its extreme open position in which position the door is releasably held againstswinging closed;

Fig. 5 is a fragmentary view taken along the -line and in the direction of the arms 5-5 of Fig. 2, having parts broken away and in section to show certain details of construction;

Fig. 6 is a perspective view of a part of the device shown removed therefrom;

Fig. '7 is a View partly in elevation and partly in section of the cooperating door check parts,

' taken along the line and in the direction of the arrows 'l'! of Fig. 3, and 1 Fig. 8 is a view similar to Fig. '7 taken along the line 88 of Fig. 4.

Referring to the drawings by characters of reference, the numeral 10 designates in general, a vehicle body, vertical door frame member or hinge pillar on which, a door II is mounted by suitable vertically spaced hinges I2, the pillar l0 and the door ll having opposed end walls I3 and M respectively which are recessed to receive respective leaves of the hinges. Within the-pillar It], a reenforcing or backing plate I5 is secured to the pillar wall l3, the plate l5 and wall-l3 having aligning apertures to receive a bracket l6 which is provided with a head l1, within the pillar, which head ll abuts and may be rigidly secure to the backing plate [5 by any suitable means. The bracket I6 is provided with a pair of vertically spaced arms 18 extending toward the door end wall I, externally of the pillar, one end of a checkarm 20 is pivoted to and between the arms I 8 by a pivot pin 2|, preferably a rivet.

Within the door II, a retainer, casing or cage 22 is provided having outturned flanges 23 which scat against a backing plate 24 which forms one wall of the retainer, the flanges 23, backing plate 24 and the hinge door end wall I4 being provided with aligning apertures to receive rivets 26 for rigidly securing the reenforcing plate and cage to the door. "The casing 22 includes a wall 22a, spaced from and substantially parallel to the door end wall 14 and the backing plate 24, door end wall l4 and the casing wall 22a are provided with aligning openings or apertures through which extends the check arm 20 which projects into the door having therein a free end on which is provided and secured a buffer 21 preferably made of rubber or other suitable resilient material.

Positioned within the casing or retainer 22, a pair of yieldable cam-like bearing members or detents 28 are provided and are arranged to engage opposite sides of the check arm 20, these bearing members being yieldingly urged against opposite sides of the check arm 20 by individual, resilient or yieldable means such as spring members 29. The spring members 29 are, in the present instance, bowed leaf springs, the

crowns of which engage respectively the bearing members 28 and the ends of which springs abut the opposite end walls 3!] of the retainer or casing 22, see Fig. 5. Each of the cam-like bearing members 28 is provided with an extended or riser-like cam portion which may be uniform throughout its length, as shown in .Fig. 6, providing at the high surface thereof a socket engaging preferably rounded projection 3|.

The arm 20 is provided with abutments 32 and 33 projecting from opposite sides of the arm adjacent to but spaced from the resilient buffer or stop 21, the abutments being adapted to abut and cooperate with the bearings 28 to retard swinging open of the door ll. These abutments 32 and 33 also cooperate with the buffer or stop head 2! to provide a recess to receive the bearing members 28 when the door is swung to wide or extreme open position. To provide an inexpensive arm 20, the abutments are preferably made by pressing out of the arm 20 a pair of the abutments 32 spaced and between which the single abutment 33 is pressed out of the arm in the opposite direction to the abutments 32. These abutments 32 and 33 have rounded surfaces and where they join the arm 20 provide oppositely directed sockets 35 and 36 in which the socket engaging projections 3! of the yieldable abutment or bearing members 28 are adapted to engage.

In operation, when the door II is swung open far enough, the abutments 35 and 36 will come in contact with the yieldable members 28, the extended projections 3| of which will engage in the arm abutment sockets 35 and if the door tends to open further, the abutments 32, 33 will partially rotate the yieldable members 28 tending to move them away from each other and further tensioning the springs 29 which will act to retard the further swinging of the door. If the door is swung open with sufiicient force or if moved with the intention of opening it to its wide open position, the abutments 32 and 33 will partially rotate the yieldable members 28, forcing them apart until the abutments have passed over the projections 3| after which these portions 3| will engage back of the abutments 32 in the sockets 36 as shown in Fig. 8 for yieldingly holding the door I I in open position; When the door H is again closed, the abutments pass back between the members 28 forcing them apart for necessary clearance and the members are partially rotated back to the positions shown in Fig. 7.

While I have shown and described my invention in detail it is to be understood that the same is to be limited only by the appended claims for many changes may be made without departing from the spirit and scope of the invention.

What I claim is:

1. In a door check device having a check arm provided with spaced abutments providing a recess therebetween, a check device cooperable with the check arm comprising, a retainer through which the arm extends, a pair of bearings in said retainer for engaging opposite sides of the arm and having socket engaging projections, said bearing members being movable away from each other so that one of the abutments may pass therebetween and the bearing members positioned in the recess formed by the spaced abutments, said socket engaging projections engaging said one abutment when said bearing members are positioned in said recess, and yieldable means acting to hold said bearing members in engagement with opposite sides of said arm.

2. A door check and holding means comprising, an arm member having an abutment intermediate its ends providing a socket, a retainer member, one of said members being mounted on the door and the other of said members bein mounted on the door frame, a pair of bearing members in said retainer and between which the arm extends, said pair of bearing members having extended socket engaging projections for engaging in the socket formed by said abutment, and a second abutment on said arm and cooperating with said first-named abutment to provide a recess therebetween to receive said bearing members, said bearing members being movable away from each other by said first-named abutment to position in said recess and biased toward each other.

3. A door check and holding means compriss ing an arm member having an abutment providing oppositely directed sockets, a retainer member through which the arm extends, said members being relatively movable and one of said members being carried by the door, a pair of rollers in said retainer and engaging opposite sides of said arm, said rollers having extended surface projections for engaging one or the other of said sockets, and spring means urging said rollers into engagement with opposite sides of said arm.

4. A door check and holding means comprising an arm member having an abutment providing oppositely directed sockets, a retainer member through which the arm extends, said members being relatively movable and one of said members being carried by the door, a pair of rollers in said retainer and engaging opposite sides of said arm, said rollers having extended surface projections for engaging one or the other of said sockets, and bowed leaf springs in said retainer and urging said rollers toward each other into engagement with opposite sides of said arm.
