Patented Oct. 18, 1938 ‘ 2,133,351 UNITED STATES PATENT OFFICE 2,133,351 DOOR STOP Birkelund Hansen, San Francisco, Calif. Application October 2, 1937, Serial No. 166,993 5 Claims. (01. 16-137) ' The present invention relates to improvements in door stops, and has particular reference to a stop that is adapted for holding a door in open position. In making repairs on an automobile and servic trated a body post I having a door 2 secured thereto by means of a hinge 3 in the usual man chanic to gain access more easily to the different Which are journalled on a vertical pin, as at 6'. 10 parts. It will be understood that when the door is closed the faces 6 and ‘I of the body post I and the door 2, respectively, contact one another. Figure 1 shows the door after it has been opened to a posi -An object of my invention is to provide a door 20 stop, which is adapted to be fastened to one of the door hinges in such a manner that the stop will hold the door against closing until such time as the stop has been removed. A further object resides in the provision of a 25 door stop that will allow further opening of the door from an initial open position. The stop is made for automatically extending itself when the door-opening is widened so as to maintain con tact with the door. A still further object is to provide a door stop 30 that will automatically lock itself against return movement in any position to which it may be ex tended. Moreover, I propose to provide a door stop 35 adapted to be applied to the hinges on either side of the automobile or the like, and which will be ?rmly anchored in position after being attached thereto. Other objects and advantages will appear as _ 4,0 the speci?cation proceeds, and the novel fea tures of my invention will be particularly pointed out in the appended claims. For a better understanding of my invention reference should be had to the accompanying 45 drawing, forming part of this application, in which: ' ' Figure 1 is a fragmentary horizontal sectional view taken through a body post and a door, the latter being open, and showing my door stop in operation; Figure 2, a sectional view taken along line 2—2 of Figure 1; Figure 3, a face view of my door stop; and Figure 4, a plan view thereof, parts being shown 55 Referring to the drawing in detail, I have illus ing various parts thereof, such as the instrument board, transmission, battery, etc., it is quite desir able that the door of the automobile be main tained in open position, thus allowing the me~ It is proposed in this connection to provide a stop, which may be readily‘applied in place for holding the automobile door open. It will, of 15 course, be understood that my door stop is not to be limited to this particular use, and I will describe the stop with reference to an automobile door merely by way of illustration. 50 Although I have shown only the preferred form of my invention, it should be understood that va rious changes, or modi?cations may be made within the scope of the claims hereto annexed without departing from the spirit of my invention. 5 in section. ' ner. The hinge comprises two straps 4 and 5., tion at right angles to the side 8 of the automobile. 15 My door stop is indicated generally at 9 in the several views, and includes in its structural fea tures a substantially T-shaped body member ID, having the arms ll of the T slotted, as at l2, for 20 engagement over the hinge strap 4. The stem I4 of the T-shaped body member extends through the space, which is de?ned be tween the body post and the door when the latter is opened, and in Figure 1 the stem is substan tially parallel with the automobile side 8. The 25 free end of the stem [4 has a squared opening I5 formed transversely therein for slidably re ceiving a rod I6, the latter also being square in cross-section. It will be understood that the opening I5 and rod "5 may be round, if 30 desired. In Figures 1 and 4, I show the rod It as hav ing an enlarged head H, which is urged away from the stem M by means of a spring l8 work ing between the stem and the head. The latter abuts the face 1 of the door in the manner shown in Figure 1 in normal operation. Upon opening the door wider, the head is maintained in contact with the door by means of the spring I8, and the latter at all times prevents the stop from accidentally becoming disengaged from the hinge strap 4. ' For holding the rod I6 against return move ment in any position to which it may be ex tended, 1 form ratchet teeth l9 along the length of the rod, which are engaged by the pawl 20, (see Figure 4). The pawl is urged into the as space between the teeth by means of a spring 2| interposed between the squared head 22 of the 50 pawl and a sleeve 23, the latter being threaded into the end of the stem l4. A handle 24 may be manually retracted for disengaging the pawl from the ratchet teeth and thus allow the head IT to move toward the stem 2 2,133,351 I4. The head 22 of the pawl may be guided in a squared guideway 22', if desired. The rod It extends laterally from the stem at right angles with respect to the arms ll of the door-abutting opened into substantially the position it occupies in Figure 1. Having thus described the various parts of my invention, the operation of the door stop may be readily understood. The door 2 is ?rst The spring 18 is then compressed when the door-opening is widened so as to main by moving the head I‘! toward the stem 14, and tain contact with the door, and means for auto the stop is placed in position by engaging one’ of the slots l2 over the hinge strap 4, (see Fig ures 1 and 2), with the head I‘! abutting the any position to which it may have been extended. 3. A door stop comprising a body member hav 15 face of the door. ing means for securing the member to a hinge It is apparent that upon opening the door 2 further the head I‘! is maintained in contact with the door by means of the spring 18. The 20 rod [6 moves to the right in Figure 1 as the door opening is widened, and the ratchet teeth l9 are free to move beneath the pawl 20. However the rod is held against return movement from any extended position by means of the pawl, unless 25 the latter is ?rstv released by manually retract ing the handle 24. When the door stop is applied to the right hand door of the automobile, with the hinge ar ranged at the front of the door, the slot I2’ is 30 engaged over the hinge strap 4'. Upon applying the stop to the left-hand door, with a similar matically locking the door-abutting means in strap, and a rod adjustable transversely in the member and arranged for abutting a door for holding the latter against closing, the rod having ratchet teeth thereon, and a pawl engaging the 20 ratchet teeth for locking the rod against return movement after the rod has been extended from the member. 4. A door stop comprising a body member hav ing means for securing the member to a hinge 25 strap, a rod adjustable transversely in the mem ber and having an enlarged head thereon ar ranged for abutting a door for holding the latter against closing, and a spring working between the member and the head for automatically maintaining the latter in contact with the door hinge arrangement, the stop is turned upside as the door-opening is widened. down and the slot I2" is used for anchoring 5.
