DOORCHECK Filed Nov. 27, 1934 INVENTOR Flam/P0 H. WRIGHTL ATTORNEYS Patented A r. 2, 1935 I I 1 99 UNITED STATES PATENT OFFICE noononnon Richard B. Wright, Cleveland Heights, Ohio Application November 27, 1934,, Serial No. 755,048 5 Claims. (01. iii-a6) The invention relates to doorchecks, and pargenerally by means of a hinge post I. The numticularly to those types of doorchecks, which are her of hinges applied to the door is immaterial, especially applicable to doors for automobile or although there will generally be found at least other vehicle bodies, and the like. a two and frequently three.

In the past, these have taken to which the same is subjected in checking and the form of leather straps, cables, plungers, etc. restricting the movement of the door.

and illustrates a modified construction wherein As previously mentioned, the buffer according the ends of the cross-head are flared outwardly. to my invention, is of novel construction, and Like characters designate corresponding parts preferably assumes the form of a. resilient sleeve "in the several figures of the drawing. which may he slipped onto. the cross-head arms Referring first to Figures 1 and 2, there is so as to be retained thereon by the resiliency of 50 shown by way of illustration a door I mounted the sleeve. In practice, it has been found'desirupon the vehicle body, generally designated 2, able to thicken the sleeve at one side so as to by a hinge 3, one leaf 4 of the hinge 3 being at-.- provide an abutment engaging section of sumtached to the hinge edge 5 of the door and the cient massto satisfactorily cushion the shocks other leaf 6 being suitably attached to the body created in restricting the movement of the door 55 at its limit or travel in'an opening direction. In

the drawing,- the sleeve is designated generally by the reference character It, while the thickened section of the sleeve ,is designated l5.

Likewise, I have found, in practice, that it is desirable to a provide some means for positively interlocking the buffer sleeve on its supporting arm so as to insure that the thickened section of the sleeve will remain in proper position to receive and absorb the shocks. Without such interlocking provisions, the sleeve has a tendency to turn on the arm eventually so that the shocks are received by the relatively thinner walls of the buffer, which, of course, do not have the capacity for absorbing the same as does the thicker wall.

To produce this interlock betweenvthe bufler The central openings through the buffer sleeve is preferably slightly smaller than the supporting arms so as to providea snug fit, the resiliency of the buffer serving to maintain the bufler on the arms without the additional provision for securing the same thereon.-

The material from which the buffer is made is preferably rubber. Other suitable resilient compositions may, of course, be utilized.

In mounting the doorcheck, it may be located anywhere between the upper and lower extremities of the door, as desired. Likewise, if desired, more than one check can be provided per door. In practice, however, one per door will generally be found suflicient.

The operation of the invention should be readily apparent from the foregoing, and is" briefly summarized as follows:--

Assuming the door to be at the limit of itsv open position as shown in Figures 1 and 2, upon closing the door, the shank 8 will slide through the aperture I2 to the left, (as observed in the drawing), pivoting about the point I i, as it does so, and keeping closely adjacent to the outer wall of the vehicle body so that in final closed position, the buffer supporting end of the shank will be substantially spaced from the hinge position 2. Upon opening the door, the shank 8 will be withdrawn .through the aperture l2 until the buffer strikes the inner face of the'hinge post I. The impact shock will be absorbed by the thickened wall ii of the buffer, which-wall is located so as to extend towards the hinge post 1 for abutting thereagainst, being positively retained in such' position by the interlocking of the rib I6.with the channel l1.

If desired, the cross-head I! may be provided with lugs I311 so that when thesleeves have been arranged upon the cross-head, the lugs or lock- ..ing meansmaybebentsoastomaintain the may also be aconflguration as illustrated in Figure 8, and the flared ends ilo will eliminate; 'the possibility of accidental displacement of the rubber sleeves.

It will be obvious that the doorcheck described herein may be mounted in a reverse order with respect to the automobile body and door. In other words, the bracket 9 may be secured to hinge post I, while the parts 8, i3 and- I4, may be operatively arranged ture'oi. the door I.

while the specific details of construction have been herein shown and described, the invention within the frame struc is not confined thereto, as changes and alterations may be made without departing from the spirit thereof, according to the appended claims. Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:-

1. A doorcheck of the class described, comprising ashank, one end of which is adapted to be attached to the hinge edge of a door, and the other end of which carries at least one laterally extending arm adapted to coact with an abutment for limiting the movement of the door, and a buiier carried by said arm, said buffer comprising a resilient sleeve having a protuberance extending therefrom and interlocking with said arm.

2. A doorcheck of the class described, comprising a shank, one end of which is adapted to be attached to the hinge edge of a door and the other end of which carries a cross-head comprising'cpp'ositely extending arms of substantially U-iorm adapted to coact with an abutment for limiting the movement of the door, and a buifer mounted on said arms, said buffer comprising a resilient sleeve having an internal protuberant rib received within the channel formed by the U-shaped arms.

3. A doorcheck of the class described, vcomprising a shank, one end of which is adapted to be attached to the hinge edge of a door and the otherend of which is provided with at least one laterally extending arm adapted to coact with an abutment for limiting the movement of the door, and a bufier mounted on said arm, said buffer comprising a sleeve of resilient material'slidable onto said arm and adapted to be maintained thereon by the. resiliency of the sleeve, said sleeve being thickened at one side to constitute the abutment engaging portion.

4. As a new article of manufacture, a butter for doorchecks of the class described, comprising an extruded sleeve of resilient material, the

wall of said sleeve being thickened at one side to constitute an abutment, engaging section and provided at the opposite. side with .an internally protuberant longitudinally extending interlocking rib.

5. A doorcheck of the class described, comprising a shank, one end of which is adapted to be attached to the hinge edge of a door, and the other end of which carries at least one laterally extending arm adapted to coact with an abuting therefrom and interlocking with said arm,

and locking means on said arm for maintaining the buifer against displacement.
