DOORCHECK.
Application filed April 22, 1927. Serial N0. 185,809.
This invention pertains to a door check, and particularly that type of overhead metallic check applicable to vehicle doors and the like, for limiting their outward swinging movement.
The principal object of this invention is to provide a check of the above'character of simple and economical construction, and which will have a double spring bumper action when the door is moved to extreme open position and to extreme closed position.
The former action serves to absorb the shock when the door is thrown open, limiti ng the opening movement of the door. and as above noted, the shock will be absorbed by a centrally-positioned spring which is engaged and compressed from both ends toward the center.
Another feature of the invention resides in the arrangement of the shock absorbing spring in such position and manner that upon the door approaching closed position, the spring will be compressed so as to absorb any undue shock in slamming the door closed,
and will also maintain the check under spring tension when the door is in closed position to prevent rattling thereof.
The full nature of the invention will be understood from the accompanying drawings and the following description and claims:
In the drawings, Figure 1 is a side elevation of the check in closed position mounted between the top of the door and the door frame. Fig. 2 is a plan view of the check showing it mounted upon the door and door frame with the door in partially opened position. Fig. 3 is the same as Fig. 2, showing the position of the check with the door in open position. Fig. 4 is a longitudinal sec tion through the check and a portion of the door and frame with the door in extreme open position. Fig. 5 is the same as Fig.
' 4 showing the check with the door in closed position. Fig. 6 is a section taken on the line 66 of Fig. 4. Fig. 7 is a modified form with respect to the mounting of the check, showing it secured to a metal door frame.
In the drawings there is shown a vehicle door 10 mounted in the usual manner'in a longitudinal slots 15 and 16 extending from one end to the other. The link 14 is pivotally connected with the upper part of the door frame 11 or header through the medium of an anchor plate 17 rigidly secured thereto by the screws 28 and countersunk in the surface thereof in the usual manner. The link 13 is similarly pivoted to the top of the door through the medium of the anchor plate 18. countersunk in the upper surface thereof. However. it may be herein noted that the anchoring device for pivotally securing said links to the door or door frame may be of any approved form or construction. such as an angle plate. a bolt, or as shown in the moditied form of Fig. 7 which will be hereinafter described. I
As best illustrated in Figs. 4 and 5, the anchor plates 17 and 18 have rigidly secured therein the cylindrical boss members 20 having spacing flanges 21 and internally screw threaded to receive the attaching screw 22. Thus the links are spaced from the anchor plates and the surface of the frame or door so as to pivot freely with respect thereto about the boss 20 which receives the strain so as to relieve the attaching screw 22 of any shearing action, as is well understood in the art.
The header of the frame is spaced from the top surface of the door to freely accommodate both links superimposed" one upon the other, as shown in Fig. 1, the link 14 attached to the header being positioned immediately above the link 13. Saidlinks are maintained ting themto slide longitudinally withrespect to each other. When thus positioned, the slots 15 and 16 register with'each 'other,and have mounted therein, and within the sliding member 23, a coiled bumper springfitfsarild bum er sprm *eXtendin the en 0 t e slidi g me b and being securedillerein by a-downyva'rdly extending ear 25 stamped from the top of said member so as to extendlinwardly and engage between adjacent coils of said spring substantially intermediate its ends. The ear 25 maintains the coil in proper position, leaving its opposite ends free to receive the shock and be compressed inwardly toward each other.
From the above described construction, it will be noted that when the door is partially opened, as illustrated in Fig. 2, it will cause said links to slide longitudinally of each other, while the tendency of the sliding member 23 will be to retain its position temporarily with respect to one of said links, whereby the other link will be moved with respect ther'eto until the end of its slot will engage one end of the bumper spring 24. It will then force the sliding member to slide with respect to the other link as the door is further opened, until the other end of the bumper spring engages the end of the slot on the other link, whereby the check will be in the position shown in Fig. 3. Upon reaching this position, the further movement of the door is arrested and the shock of the arresting movement is absorbed by the compression of the bumper spring from both ends toward the center through the force applied thereto by its engagement between the ends of the slots 15 and 16.
As the door is moved to closed position, the links are permitted to freely slide in opposite directions, one over the other, until the opposite ends of the slots come in contact with the ends of the spring, as shown in Fig. 5. This position is reached just prior to the door reaching the closed position, and such engagement arrests the movement of the door so as to prevent slamming thereof and causes the springs to be compressed as the door is fully closed and latched. Upon the door being completely closed, the spring will be under tension between the ends of the slots so as to prevent any rattle of the structure caused by vibration of the vehicle when moving with the doors closed.
As shown in Fig. 7, the header of the frame 11 is formed of sheet metal and is provided with the same boss 20 with the flange 21 which is secured to the anchor plate 18, said anchor plate being secured against the inner surface of the metal header between the flange 21 and the riveted end of the boss, all in accordance with the well known practice.
The invention claimed is:
1. A door check comprising a pair of links having longitudinal slots therein. means for pivotally anchoring each of said links at one end thereof, and a slide member slidably supported by both of said links intermediate their ends for maintaining said links in alignment While permitting them to slide relative to each other.
