3 Claims. (01. 29251) This invention relates to systems for locking simultaneously all of the doors of a multiple door vehicle and it relates particularly to a looking system whereby all the doors of an automo- -bile may be locked and unlocked by means of a single exterior locking handle.
In accordance with the present invention, I have provided a simplified locking system including movable bolts for locking and releasing each of the doors of the vehicle, these bolts being projected and retracted by means of suitable actuating members mounted for movement in the pillars of the vehicle body adjacent to the free edges of the doors. The several actuating members for the bolts are interconnected V by means of a closed hydraulic system including hydraulic cylinders or jacks which are arranged so that movement of one of the pistons of a jack will cause all of the other pistons to move simultaneously thereby actuating all of the bolts at the same time to lock or unlock the doors.
In order to provide a simple and rugged system which can be operated with a minimum of thought, the pistons are so arranged that outward movement of one of the pistons will actuate one or more bolts, while inward movement of the piston or pistons at the opposite end of the system will operate the locking bolts at the other endof the system. This arrangement of the cylinders or jacks is especially desirable in- ;asmuchas it permits the operating handles which are connected with the pistons and exposed at the exterior and the interior of the vehicle to move in the same direction for locking and unlocking the doors.
7 Through the use of hydraulic connections between sturdy operating cylinders, a foolproof mechanism is provided, which is not readily susceptible to damage and which is operable independently of other mechanisms of the vehicle.
For a better understanding of the present invention, reference may be had to the accompanying drawings in which:
Fig. 1 is a schematic layout of typical locking system embodying the present invention, parts thereof being shown in section and exaggerated in size to disclose details of construction; 7
Fig. 2 is a view in side elevation and partly .in section of the device taken on lines 2-2 of Fig. I;
T Fig. 3 is a view in elevation and partly in section looking in the direction of the arrows 3-3 of Fig. 1; and
E 5. 4 is a view of h ope ati h nd e 1 inner ends of the bolts l5 and i6.
ing in the direction of the arrows 44 of Fig. '1.
The invention will be described with reference to its use in a vehicle of the type having four doors. In this vehicle, the doors on both sides of the vehicle are hinged at their opposite vertical edges so that their free edges are adjacent a central pillar; that is, the front door on one side of the vehicle opens at its rear end while the back door on the same side of the vehicle opens at its front end. The invention is, however, equally applicable to vehicle door arrangements in which both of the doors are hinged at their rear edges or their front edges, as is the case in some body styles.
Referring now to the drawings, the vehicle body includes the central pillar ID on the lefthand side of the car and the pillar II on the right-hand side of the car which lead into and form a support for the top or roof l2 of the vehicle. The pillar and top construction is conventional, does not form a part of the invention and therefore is not illustrated in detail. As shown in Fig. 2, the pillar It] forms a dividing section between the front door 13 and the rear door 14, both of which are hinged to the body at their outer ends so that their inner free ends. l3a and Ma substantially abut the sides of the pillar Ili when the doors are closed.
The doors may, of course, be provided with conventional locks and door handles. Both of the doors l3 and I4 further may be locked 'to the pillar by means of the pivoted bolts 01' latches I5 and I6 which are supported for rock'- ing movement on the pivot pins l1 and I8. The outer end's'of the bolts l5 and 16 are normally disposed within the side flanges Illa and 10b of the pillar [0 but can be projected into slots or recesses l9 and 2B in the abutting faces of the doors I3 and [4 by rocking their inner ends downwardly. The bolts l5 and I6 are normally retracted by means of coil springs 2| and 22, re-
spectively, anchored at one end to the interior of the pillar and at the opposite end to the Other types of springs or. their equivalent may be substituted for the springs 2| and 22, of course.
The bolts 15 and it have semi-circular notches 23 and 24 in their inner ends for engagement with an actuating pin 25 which projects ,outwardly from a rack member 26. The rack member 26 is guided in a bearing or bushing 21. which is fixed to the interior of the pillar in anysuitable way so that the rack member can recipro; cate axially. The pin 25 engages inner ends of the bolts and is received in the notches l3 and 7 2 91, d nward yiqvsinen and t er b iQfifi the outer ends of the bolt members into the slots I9 and 20 to lock the doors to the pillar. Upward movement of the rack member 26 in conjunction with the springs 2| and 22 rocks the inner ends of the bolts 23 and 24 upwardly so that the outer ends of the bolts are withdrawn from the slots l9 and 20 to release doors [3 and M from the pillar ID.
The pillar H at the opposite side of the vehicle also carries a similar pair of bolt members 29 and 30 which cooperate with the front and rear doors 3! and 32 in the same way as the bolts 23 and 24 cooperate with the doors l3 and M. The bolts 29 and 30 are actuated by means of a pin 33 which is mounted on the end of and projects outwardly from the piston rod 35 which is fixed to a piston member 35 reciprocable in a hy'- draulic cylinder 33. The cylinder 33 is fixedly supported in the pillar H by means of a ring clamp 31 or other suitable support rigidly connected to the pillar ll.
The upper end of the cylinder 33 is connected by means of a conduit 38 to the upper end of another similar cylmder 33in the pillar Ii]. The cylinder 39 also has a piston to therein. A piston rod 4| is connected to the piston dB and projects from the lower end of the cylinder 39. The lower end of the piston rod 4! is in the form of a rack. -42. The rack 42 is connected with the member 26 by means of an idler pinion 43 mounted rotatably on a shaft or pin dd extending transversely of the pillar It and supported therein.
The pistons 35 and 40 are so positioned in their respective cylinders that when the piston '40 is in its lowest position, piston 35 is in its upper position. Therefore, when the piston '48 is retreated by downward movement of the rack member 126 to project the bolts 23 and 24, the piston rod 3-4 is projected so that the pin 33 thereon will engage andproject the bolts 29 and ,30 to lock the doors 3| and 32. 'In this way, movement of either of the piston rods 34 and M will cause movement of the other piston rod to either look all the doors simultaneously or unlock them simultaneously.
-.To facilitate operation of the locking system, the rack member '26 is provided with a handle member 45 which is exposed on the outside of the pillar *ll through a slot 43 to permit up and down movement of the handle. If desired, the piston rod 34 may also have an inwardly extending handle 4'! which permits operation of the bolts from the interior of the car.
It will be understood that the locking handle 45 has a conventional key lock or its equivalent so that it can be locked in the closed position to prevent entry of the car. Any conventional key lock may be used for this purpose.
The system, while described above with ref memo to the use of two pairs of bolts actuated by two cylinders, is equally well adapted for use with vehicle doors which do not have their free edges adjacent to a common pillar. In this arrangement, it is only necessary to provide separate cylinders like the cylinder 36 for three of the doors while a single master cylinder 39 is used for the fourth door. The three auxiliary cylinders will, of course, individually have a smaller liquid capacity than the master cylinder '39 sothat all of the piston rods can move a sufiicient distance tooperate the bolts. 7 p Also; while pivoted bolts havebeendisclosed "inthe system, it will be understood that re- 7 ciprocabl-e'bo1ts may be used equally well. These Number bolts may be actuated by suitable tapered cams or wedges on the ends of the rack member 26 and the piston rod 34 to project and retract the bolts.
Accordingly, it will be understood that the above-described embodiment is illustrative and should not be regarded as limiting the scope of the following claims.
I claim:
