UNITED STATES PATENT ,OFFlCE JOHN E. ERICKSON, OF SEATTLE, WASHINGTON.
Application filed September 24, 1925. Serial No. 58,319.
This invention relates to improvements in door checks, and similar devices' and has for its principal object to provide a mechanism adapted to be used with various types ot' hingedlymounted doors as a means of yieldably holding the door at different open positions to which it might be moved and which embodies a means that may be lactuated to positively retain the door in closed position or at any open position.
More specilically stated, the invention resides in the provision ot' a door check embodying a series ot' rigid, pivotally joined bars, or links, adapted for pivotal connection with the door and also with a stationary parteil the door frame, in such manner that there will be movement of the links relative to each other incidental to opening or closing movement of the door which will cause one of the links to move slidably within a lifted guide embodying a friction brake, or clamp, whereby a holding tension is placed on the link so as to preventmovement ot the door except by the placing of suilicient pressure against it to overcome the holding` pressure oir-tension ot the brake. i l p Another object ot the invention is to provide means for increasing or decreasingthe `tension providedin the brake so that more orless pressure will be required to close and openthe door. p v
Other obiects reside m the various details of construction of the various parts therefor and in their mode of operation.
In accomplishing these and other objects of the invention, I have provided the improved details ot' construction, the preferred forms ot `which are illust 1ated in the accompanying drawings, wherein .Figure l is a perspective view oi a truck door equipped with a check embodied bythe present invent-ion showing the door being held thereby in open position.
Figure 2 is a plan view of the device showing the relation of parts when the door is open. i
Figure 3 is a plan view illustrating the relation oi' the various parts of the device when the door is closed.
. Figure l is an enlarged section, taken on vline ilu-t in yFigure 2, showing the guide bracket and brake.
Figure 5 1s a detail View of the lholding mechanism.
Figure 6 is a view, diagrammatically il` tance spaced `from the bracket 5. bracket 22 has an inwardly turned horizon lustrating a mechanism ot an alternative type.
body of that type generally used for delivery wagons, having an opening 2 at the rear that is fitted with doors 2u mounted by hinges t So as to swing horizontally` between closed and open positions. Fixed to the inner side ot the rail 5 that terms the top ot the door frame or casing is a bracket-l5 having' an inwardly directed, horizontal lange .7 to which one end oiia bar 8 is pivotally lived by a rivet, or the like, 9, so that it may swing horizontally into and irom the door opening. As is shown beetl in Figures lv and Qthe bracket 6 is disposed adjacent that side of the opening at'which the door hinged and the bar 8, by a connection presently described,
is caused to swing horizontally into and from the opening in accordance with closing or opening movement ot the door. lnorder that this movement may not be interrupted when the door is fully opened, thebar 9 is curvedlaterally near its inner end, as at4 10. The outer end of the bar 9 is slidably contained within a sleeve l2 fitted thereto and which, at its outer end, is pivotally attached by means of a bolt 1B to a bracket 14 that is fixed to the door near or toward its outer edge. The arrangement is such that as the door Vis moved between open and closed positions, the ,outer end of the bar is moved slidably within the sleeve. At its inner end the sleeve is provided with a lon-` gitudinally extendedslot 15 with laterally directed spaced apart ears 16S-,1G at opposite sides of the slot through ywhich a bolt 17' extends and which provided with af wing nut- 18 that may be tightened onthe bolt to, clamp the sleeve tightly against the bar tollock the door in open position.
Pivotally fastened by means of a rivet 2O to the bar 9 near its inner end, is a straight bar 21`which is slidable within a clamping bracket that is fixed to the inner side of the top rail 5 of the door trame atv some dis- The tal flange 22 across which the bar 2l slides beneath a plate 24 that is clamped across the i topl surface of the bar by means of two bolts held by nuts 27 to press the'plate against 25-25 extended through the flange 22 and' plateand on which springk washers 26 are "ablein the door.
the bar to yieldably resist sliding movement of the bar through the clamp; The desired tension may be obtained by loosening or tightening the nuts.` i i i i lith the parts constructed and assembled as described, it is apparent that When the door is in open position, as shown in Figure 2, the bar 21, as connected with thebar 8, acts as a b 1ace for holding the door in open position. The tension of the brake may be sufficient that it will require considerable pressure on the door 3 to cause the bar to slide Within the clamp and thus the door Will not be swung to closed or open position by wind or by an unlevel position oi the door. It it is desired to liiositively hold the door to hold it at any adjusted open position, thisniay be done by tightening the nut 18 to clamp the sleeve l2 against the bar 8 so that it cannot slide therein.
y Then the door is closed the bar 2l still bracket 22. c
` In "order to provide means .tor positively holding the doors through the mechanism above described, I have provided a `bracket 30" on the under side oi? the sleeve 12 on Which a cam 32 is pivotally mounted and which by rotation may be tightened against the bar 8 through a `slot 33 cut .in the under side of the sleeve. j c i `The cain may be rotated through mechanism comprising a link 3d that is pivotally iixed at its inner endto the cam and at its outer end to one arm oiE a bell crank 35 mounted on the door. The other arm oit the bell crank has a link 36 `attached thereto which extends downwardly yand pivotally `coiinfected with an arm or lever 37 `that extends laterallyfroni a shaft o8 'that is rotat- At its outer end the shaft has a lever 39 whereby it may be rotated to effect movement oi the cam between holding and releasingpositions. i The lever arm 39 `is provided with a slot 40 for receiving a i iixed post il on the door andthe lever may be fixed against movement by suitable means such as a padlock 42 to" prevent release of the cam.
" While I have described the door check and lock as used on truck door it is readily apparent7V and" it is iintendetb that such def vices be used tor all types of doors such/as those in residences, oiiices,` passenger" cars;
` garages? delivery `Wagons, etc., as vvell as `for hinged `windows, transoms and box covers.
In figure G I have illustrated diagrammatically an alternative mechanism designed for control from the driverle seat of. an automobile or other vehicle employing an internal combustion engine as its motive means. The manipulation of the device from hold ing-to released position also closes or opens the circuit to the motor so that the motor cannot operate While the vehicle doors are open or released. 1
The construction may be ot various types but one which is easily ope able and which is here shown confus ot a shaflt 5() that adapted to be rotatably supported in brackets 5l so as to extend Within the top of the vehicle 'from iront to back. ht ite rear end the shaft has a lever erin 52 iixeil thereto for actuating a looking pin 53 car ried by a bracket 5ft into and from an apcr ture 55 in the bar 2i to retain the door closed.` The shaft 50, at its forward end,
has an arm 5G at 'ached to which aspiring 57 is lined to rotate the shaft to release the lock, and a cable 555 is attacherfl thereto and Til Li l") lib ivardly causes, through the conncction` shown, the shalt 50 to be rotated to release the lock pin 53 .trom the bar 21.` y
When the lever GO is down, it cngag with tivo contacts Gl and G2 in the ignition circuit so as to close the circuit to the motor and When in raised position, it disengages the contacts to open the circuit. Thisinsures that the vehiclecannotbe in motion when the doors are unfastened. Loes ot material and damage to doors is thus` avoided.
It is further apparentthat various changes in the details ot construction could be made Without departing from the spirit ot the inventionand 'for this reason I do not wish to be confined only to the details herein illustrated# Having thus described my invention, what I claim as new therein and desire to seclill'e by Letters Patent, isf
