CHECK-STRAP FOR DORS. x
Application filed Detober 6, 1920. Serial No. 415,135.
To aZZ wim/m t may concem':
Be it known that I, lllirrnn l). Dom., citizen of the United States, residiim` at Detroit, county of lllayne, Statefof Michi- D gan, have invented a certain new and usei`ul lmproven'ient in Checlrstraps for Doors, and declare the tollowir-.gto be a full, clear, and exact description ol" the same, such as will enable otl ers skilled in the art to which it pertains to malreand use the same, reter ence being` had to the accompanying drawings, which term part of this specification.
T his invention relates to improvements in swinging doors and particularly to doors tor automobile closed bodies, or other similar vehicles. More particularly, theobject is to provide a door check adapted to limit the outward swinging movement of the door. This check comprises a strap, one end oi which is attached to the door, the other end secured to the jamb to which the door` 'is hinged. rlfhis strap limits the outward swinging;v movement of the door and upon the closing` ofthe door is withdrawn within the j amb so as to be completely hidden from view.
Means are provided whereby the strap will be retracted within the jamb upon the closing,` ot the door at any position to which it 3 may have been opened for admittingv or dis-- embarking of passengers Jfrom the vehicle.
In the drawingg Figure l is a. plan view of a door hinged to a section of a jamb, showing` my device in position, 'the body ot the vehicle from which the door is swung beine` in section.
Fig. 2 is an elevation of my device.
Fig. 3 is a side view.
Fig. el is a vertical sectional view showing the strap, spindle and actuating spring' in elevation and that portion ot' the strap down about the spindle in cross section.
Let a.' indicate a swing-ing` door pivoted to the side` wall or jamb Z) of the body of a vehicle, such as an automoliiile. rl`his janib is cut away, as shown in Fig. l, to receive my device therein. The lining of the body is adapted to cover this recess so that the device will not be exposed to view.
I provide a lleXible member or strap c one end ot which is secured to the door, as indicated at (Z, and the other end of which is resiliently attached to the jamb within a provided recess in such jamb, in such a manner that when the door is opened the strap is withdrawn trom the jamb until it arrives at a predetermined position where its with-- drawal is completely arrested. lv/Vith the closing" or' the door the strap is retracted by means of the resilient-connection -it makes withthe jamb. lll/leans are provided, however, to prevent retraction of the strap and closing` of the ldoor without the interposition of outside torce to close thedoor.
rlhe object is to permit the door to'stand in an open position without being held `in such position, while ensuring that the strap will vbe withdrawn within the jamb when the door is closed. rlhe end of the strap opposite the endattached to the door is secured to a spring-actuated spindle e carried by a casing,1 j", which casing is adapted to be secured to the by means of screws passed thru its extendedv ends, or in 'other convenient manner. The spindle is heldunder rotary tension by means of an encircling spiral saring g, one end of which is secured to the spindle and the other endto the supporting casing" in such a manner that the spindle will be rotated to wind the strap around the same, thereby retracting the strap within the amb. ALs a matter of convenience, a section of strap of lesser widthy is shown as being secured to the spindle and lastenedon the wider strap which'is secured to the door. However, this serves no necessary purpose. i i
The strap, as it passesover the edge ot the jamb, rides over a roller Zi carried by aplate z' which is secured to the jamb. T he roller Zi, as shown, is carried in a bead formed inthe casing and merely serves as a friction memi ber for the strap to ride over.
lt will be seen that in' the operation of this device, when the door is opened the strap' c will be withdrawn from the jamb until complete-ly unwound from the spindle, providing the door is opened suiliciently to`com`- pletely unwind the strap and that-this will provide a limit `to which the door can he opened. This limitation of the opening of the door is essential to protect the hinge Za by means of which the door is pivoted tothe j amb. lhen the door is closed the strap will be retracted, due to the action of the spring on the spindle pulley e and the strap wound around such spindle. It is the inten` tion toV provide a spring of such tension around the spindle that it will not retract the strap and close the door. However, to enlmanner as to prevent its retracting and closing the door while permitting the strap to be retracted when the door is closed.
What I claim is:
l. In combination with a swinging door and the j amb to which the same is hinged, a flexible strap one end of which is secured to the door, the otherend of which is secured to a spindle so as to be wound tlierearound whenthe spindle is rotated in one direction, such spindle carried by the jamb and mount-- ed for rotation, spring means encircling such spindle and so connected therewith and with the jamb as to maintain the spindle under rotary tension tending to revolve the same in a direction to retract the strap when the door is closed, the tension of such spring, however, being insufficient to retract the strap and close the door. e
2. In combination with a swinging door andthe j amb to which the same is hinged, a iexible strap one end of which is secured to the door, the other end of which is resiliently secured to the amb in such a manner that the strap will yield outwardly with the opening of the door and be retracted within the jamb with the closing of the door, means for yieldingly and frictionally engaging such strap in such a manner as to'resist its retraction sufficiently to prevent its retract ing and closing the door, but insulicient to prevent its retraction when the door is closed.
3. In combination with a swinging door and the jamb to which the same is pivoted, a flexible strap one end of which is secured to the door, the other end of which is received within a provided recess in the j amb, a spindle pulley mounted within said recess in the jamb for rotation7 means for exerting rotary tension onsuch pulley, the end of such strap opposite the end secured to the door secured' to such pulley so as to be Wound therearound when the door is closed, the outward swinging movement of the door adapted to be lim ited by the unwinding of the strap from around the pulley, frictional means for engaging such strap in such manner as to prevent its retracting and closing the door, but adapted to permit the retraction of the strap when the door is closed.
4. In combination with a swinging door and the j amb to which the same is pivoted, a iiexible check strap one end of which is secured to the door the other end of which is secured to :the jam, a spindle carried by oneJ of said members and mounted for rotation and to which spindle one end of the strap is secured in such a manner as to be wound therearound as the spindle is rotated, means for maintaining rotary tension on said spindle tending to rotate the same in the direction required to wind the check strap therearound and close the door, a friction bearing member so positioned as to yieldingly bear on said strap so as to resist its travel in the closing of the door, said parts so constructed and arranged that thetension on said strap will be insuiiicient to retract the stra-p and close the door from an open pos1- ltion but suiiicient to retract the strap when the door is closed by the application of external force.
5. In combination with a swinging door and a jamb to which the. same is pivoted, a flexible check strap secured at one end to the door and at the other end to the jamb, resilient connecting` means securing at least one end of said strap to the member to which i-t is fastened in such a manner that the strap willy be withdrawn under tension in the opening of the door andy which connecting means will exert tension ,on the strap tending to retract the same andl close the door, and' means yieldingly and frictionally engaging said strap to overcome Vthe tension exertedthereon by said resilient connecting means sufficiently to prevent retraction of the strap thereby and consequent closing of the door but which frictional `engagement is insuiiicient to prevent retraction of the strap by some resilient connecting means when the door is closed by the application of external force.
In testimony 'whereof I sign this specification.
