DOOR-CHECK.
Specification of Letters Patent.
Patented N0v.22,1921.
Application led December 4, 1919. Serial No. 342,378.
T 0 all whom it may con Cem Be it known that I, ADAM J. EisMAN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Door-Checks, of which the following is a specication.
This invention relates to combined door checks and retainers, and is designed to eliminate the slamming of a door and also to hold the door in open position when desired.
The object of my invention is the production of a device of this character, which is simple, inexpensive, and thoroughly eficient in the performance of its functions, and which may be either applied to a door jamb and have pivotal connection with the door or to a door and have pivotal connection with a jamb, as may be desired.
The invention consists in the novel features of construction, and in the arrangement and combination of parts to be hereinafter described and more particularly pointed out in the subjoined claims.
In the drawings Figure l is a side elevation of a wall showing a portion of a door opening and a door closing said opening with a portion of the door jamb and the door in section, and showing a longitudinal section of my improved door check and retainer in the manner it is applied to the jamb with a part thereof pivotally connected to the door.
Fig. 2 is a horizontal section taken through the door jamb and through the device applied thereto, on line 2-2, Fig. 1, the jamb being broken away at two points to show parts'of the door beneath.
Fig. 3 is an enlarged transverse section taken on line 3-3, Fig. 1.
Fig. 4 is a sectional perspective view of the device with parts thereof separated but in operative relation to each other, and with a part of the device pivotally connected to a door. i
Referring now to the drawings in detail, the reference numeral 5 designates a wall of a. building having a door opening 6 therein, a door frame including a door jamb 7, and a door 8 hinged to one of the sides of the door frame, as at 9.
Myimproved door check and retainer is herein shown as applied to the header jamb of the door, and to permit of this, said j amb is formed with a longitudinal recess or depression 10, to opposite end walls of which gripping springs 11, 12 are secured, each of which has two spaced spring members 13 which gradually approach each other at one endlgand have the ends flared outwardly, as at Arranged within the depression l0 between said springs is a metallic guide 15 which snugly fits said depression and is fastened to the horizontal jamb 7 by screws, or otherwise. This guide is formed of a strip of sheet metal bent into substantially rectangular form in cross section `with a slot 16 in its bottom wall and therefore comprises a to wall 17, side walls 18, and two inwar l -extending or opposed flanges 19 space apart to form the slotted bottom wall. This guide is therefore hollow and open at opposite ends with the slot 16 eX- tending from end to end thereof.
Slidable within the guide 15 is a check and retainer member 20, said member having an intermediate portion of cross sectional shape to correspond to the interior of said guide so that it is in physical contact with all the walls of said guide.
At opposite ends, said check or retainer member 20, which may be termed a slide, is reduced in thickness and formed with a concaved portion 21 and a convex portion 22 at both the top and bottom of each reduced portion with the outer ends of the slide rounded, as at 23. This slide has pivotal connection, as at 24, with one end of a link or bar 25, the opposite end of which latter is pivotally connected to the upper edge of the door 8, as at 26.
lVith the door hinge at the right of an opening, the slide 20 is at the extreme left of its movement when the door is closed and the left hand end ofl said slide is retained between the spring members of the gripping spring 11, which spring may be termed a check spring. When the door is swung open to the position indicated by dotted lines in Fig. 2, the slide will have been moved within the guide 15 to its extreme right position, as indicated by dotted lines in Fig. 1, with the right hand end of the slide forced between the spring members of the gripping spring 12, cwhich spring 'may be termed a. retainer spring.
It is therefore apparent that upon opening the door, the slide 20 is moved from left to right within the guide l5, and when closing the door it is moved from right to left within said guide. When, however, a door is hinged at the left of an opening, reverse action of the slide takes place, assuming the door is swung to the same side of the wall, and in such case the gripping spring 11 becomes the retainer spring while the gripping spring -12 becomes the check spring.
With the door closed, the link or bar is positioned directly underneath the guide, as best shown in Fig. 3, and one edge thereof lies against one of two depending lips` 27 arranged on one of the flanges 19 forming the slotted bottom wall of the guide, each of said lips being formed by cutting incisions in the flange and bendingV the metal between said incisions downwardly, as best shown in Fig. fl. Therefore, with my invention it will be found unnecessary to `employ the usual door stops except of course on exterior doors .where door stops .are alwags needed.
uring the act of opening the door, the slide is moved within its guide toward the hinged edge of the door and nally 4has vthat end of the slide close to the hinged edge of the door engaged by the spring members Vof the retainer spring 12, whichspring members are forced apart'until the convex portions of said slide end pass beyond the eX tremities of the spring, as shown by dotted lines in Fig. 1. Vhen the slide is in this position the door is opened to its limit and will be retained in this position so that air `drafts passing through a room cannot close the door, and it is necessary to exert sufficient pressure on the door in the direction of its closing movement to disengage the slide from the retainer spring before the door canbe closed. When the, door reachesthe end ofts closing movement,-the opposite end of the `slide engages the check spring 11, causing the spring members thereof to separate until the convex portionsV of said slide end pass the extremities of said spring members. The spring members of the check spring therefore prevent slamming of the door and necessitate'the use of some pressure. or require momentum in the movement of the door in order to completely close the latter.
It is apparent that either o f the springs may be dispensed with and one end'of the slide only be formed as shown; in which case, if the retainer spring only is used the device will serve as a door retainer only,
while if the check spring only is used, the device will serve as a door check only to prevent slamming of the door when closed by air drafts.
It is also apparent that the slide and its coperating parts may be fitted into' the upper edge of the door, with the link or bar 25 pivotally. connected to the door jamb. In the event of this device being used on a double door; that is7` oneswinging to 4ophinged to posite sidesv of the wall, the stop lips 27 on the guide 15 may be dispensed with. It is also to be noted, viewing the wall as shown in Fig. 1, that if vthe door were hinged uat the left hand end, it would be necessary to change the pivotal point 26 of the bar or link 25, and if the door were to be swung to the Vopposite side of the wall and the stop lips were to be utilized in conjunction with the bar or link 25, it would be necessary to reverse the guide in orderto bring the stop lips to the opposite side of the slot 16 within said guide.- l
