7 Claims. (01192-302) V The present invention relates to combined locking and supporting means for doors and particularly to means' of this type adapted for use in connection with motor vehicle doorswhich, as is well known, tend to vibrate in the plane of the door as the vehicle to which they are attached moves along a highway. The invention comprises an improvement upon the combination lock and door retainer disclosed in Patent No. 1,908,387, issued May 9, 1933 to J. A. Watson.
In the patent just mentioned is disclosed a combination with door and door frame members of a tongue or retainer rigidly fixed upon one of said members and a latch bolt and retainer receiving means mounted upon the other of said members. When the door is closed the tongue or retainer is not only engaged by the latch bolt but is also gripped between opposed resiliently supported jaws for the purpose of preventingthe door from vibrating relatively to the door frame. The necessity of providing entirely separate locking and door supporting means was thereby avoided, reducing the cost of manufacture and installation of these devices and effecting a considerable simplification in the door and 'door frame construction.
In accordance with the present invention the severalelements of the general combination set forth in the Watson patent just referred to are rearranged so that the benefits of such construction may be realized, together with additional benefits and advantages. Thus the wedging means, sometimes designated the tongue or door supporting member, is differently shaped and supported in a somewhat different manner so that the aperture provided therein for the reception of the end'of the latch bolt is entirely enclosed and presents no corners or edges which might be engaged by the clothes of a person entering or leaving the car door when open. Again the wedging means is designed as an elongated wedging member disposed substantially at right angles to the plane of the door, when the door is closed, and is secured at its inner end upon the door frame or other supportin ggnember, being unattached laterally to the door frame so that all of its side surfaces are exposed.
The wedge receiving means is so designed that a portion thereof lies behind the wedging means when the door is closed or, in other words, is hooked around this wedging means so that, in the event that there is any tendency on the part of the door frame members to separate, the wedging means in cooperation with the wedge receiving means and door will act as a tension member preventing such separation. This will prevent accidental unlatching of the door when the motor vehicle to which it is attachedis in transit due to failure of the body to remain rigid, which sometimes happens with other types of securing means. Again, the wedge receiving meansincludes resiliently supported jaws and the wedging 7 means isclamped between these jaws.. Preferably, although not necessarily, resilient material extends almost completely'aroundthe wedging 'means when the door is closed, this material being preferably rubber, and the. latch bolt is strongly spring pressed intolatching position in I to one skilled in the art. One form of the in vention is disclosed in the accompanying drawing byway of example but it'will be appreciated that in adapting. the inventionto vehicle bodies which differ in design, minor changes may be made to accommodate the door locking and supporting means to such design, without departure from the invention. Itis immaterial whether the wedging meansgbe upon the door'frame or upon the door and the wedge receiving means upon the other member, but in the general case the wedge receiving means and the latch bolt will be placed upon the door, and the wedging means upon the door frame, as illustrated in the'drawingt.
In the drawing:
Figure 1* is a view, partially inside elevationand partially in section of the wedging andwedge receiving means in interengaging relationship;
Figure 2 is a section on line 2-2 of'Figure 1, portions of the door being illustrated inrather diagrammatic fashion; i
Figure 3 is a section on line 3-3 of Figure" 1; Figure 4 is a perspective view of the ,wedglng means and itsattachment plate; and j I a Figure 5 is a section through a slightly modified form of locking and supporting means. r i V V V A portion of the frame ofadoor is indicated at F in the, drawing and portion of the door}it-- self indicated at D, it being understoodthat the nermost end integral with a supporting angle plate II which may be rigidly attached to the door frame member by screws l2 or other securing devices, or by welding. Wedging means l0 tapers outwardly, both vertically and horizontally, and preferably has four distinct side surfaces facing in different directions; upper and lower faces i3 and M and side faces' lfii-and l6. Sectionsthrough the wedging means parallel to the plane of the door when closed will preferably be square or rectangular. The upper and lower faces I; and I4 comprise the principal faces or surfaces which are resiliently engaged by the wedge receiving means but therear face 16 may likewise be engaged. The forward face I5 is recessed to provide an aperture H for the reception of the end of the latch bolt. It will be appreciated that the exact configuration of the wedging means will be varied but in every instance it will have upper and lower surfaces for engagement with the wedge receiving means, a laterally opening recess for the reception of a latch bolt, and a surface such as l6, rearwardly facing, and which is preferably engageable by portions of the wedge receiving means for reasons heretofore set forth. Y I
The wedge receiving-means, preferably mounted upon the door, comprises suitable housing or casing members for supporting resilient elements such as springs or the like, these elements preferably being rubber blocks such as indicated at 20 and 2|. The mutually facing surfaces of the rubber blocks are covered withprotective material, preferably-relatively inclined metallic plates 22 and 23 which may be conveniently formed as portions of a single continuous generally U- shaped member, as shown in Figure 3. This metallic member preferably has a third wedglng means engaging surface 24 for engagement with the rear surface. iii of the wedging means and 50 portion 24 is backed by a rubber block 25.
A latch bolt is indicated at 26 and a spring normally urging the latch bolt to lockingposition at 21. Any suitable means for retracting the bolt may be provided such as the customary manually operable rock shaft and operating arm, this latter being shown in Figure 1 in dotted lines at 28.
As the door is moved toward closed position the inclined face 26"of the latch bolt will contact with the rounded end of the: wedging means W and the latch boltwill be forced rearwardly against the action of spring 21 as its end rides along the face l5 of the wedging means. Finally, the end of the latch bolt registered with the recess IT and the spring 21 becomes active to thrust the latch bolt into this recess, thus locking the door in closed position. Prior tothe time that the door reaches fully closed position, however, the 'upper, lower, and rear surfaces, l3, l4 and [6 of the wedging means, have come into contact with the metallic members 22, 23 and 24, which may be designated wedge receiving jaws, and
these'jaws are laterally deflected by the wedging means as it moves to final position, compressing the'rubber backing blocks 20, 2| and25. When the door is completely closed, therefore, the wedging means I0 is resiliently clamped not only between the upper and lower jaws 22 and 23 but be tweem the jaw 24 and the spring pressed latch bolt 26. It is therefore resiliently held against vibration vertically and horizontally and may not block 25 may be omitted if desiredas shown in Figure 5, particularly in the case of very well built bodies, but I preferably make use of this additional resilient supporting means. The jaw 24 ispreferably provided in any event, even if not resiliently supported, inasmuch as by t eengagement of this jaw, or its equivalent,with the face I6 of'the wedging means, the door is locked to the door, frame in suchmanner' that the latch bolt 26 cannot become disengaged from the recess l I owing tospreadingof the pillars of the frame.
The resilient supporting means may be formed in various waysand may include metallic springs or a combination of metallic" springs and rubber blocks. be formed individually and be shaped in various ways. That form of the invention disclosed in the drawing, however, is preferred inasmuch as the several parts are of simple nature, inexpensive to produce, and may be readilyassembled together and applied respectively to the door and door rattle even when the vehicle to'which it is at- I The jaws" 22, 23 and 24 may, likewise I 1.
