Application filed August 24, 1926. Serial No. 131,202.
The present invention relates to the type of door check which embodies a slotted keepor and a pivoted arm attached to the door at one end and provided at the other with 5 lugs or projections which fit in the keeper.
The keeper opened beyo prevents the door from being nd a fixed and definite point,
requiring closing of the door before the check can be released.
This 'eneral t e of fastener well known, the
present invention relating to certain improvements thereon as will be ful ly set forth herein and defined in the claims attached hereto, which are not intended to be limited to the exact and detailed construction, but are to be given a broad interpretaof the door.
These and other advantages will appear from the drawings and description forming a part hereof.
In the drawings:
Figure 1 is a View of a door equipped with the improved door check;
Figure 2 is a section on the line 2-2 of Figure 1 Figure 3 is an enlarged view showing the door closed and open;
Figure 4 is a side view of the parts shown in Figure 3; and
Figure is a detail of the keeper.
A door is shown at 1 and the door frame To th igid arm 5,
e side panel of the door is atached a plate 3, to which is pivoted at l :1
the free end of which is pro vi led with a knob having two lugs 6 which project laterally therefrom.
The keeper 7, which is attached to the door jainb, is in the form of an elongated, boxlike structur e having a slot- 8 in its upper surface through which the end of the arm 5 may pass, but which is narrower than the width of the knob 6 so that when the knob is within the keeper except at the end thereof remote from the door, the arm cannot be moved out of the keeper.
At the en 61 of the slot remote fromf the of the spring bacltwa door, the slot is widened, as at 9, to permit the passage of the projections 6, the location of the part 9 being such that this can only occur when the dooris shut. g y
At the base of the keeper channel is secured a flat leaf spring 10, the one of which is secured near the door and close towhich is formed a hump or bent portion 11, This hump provides a detent and is so located that when the door is opened to its fullest extent with the arm engaged by the keeper, the knob at the end of the arm 5 will depress the hump and pass into the space atthe rear thereof; The arm beingrigid, the door will be held ajar, as shown in full lines in Figure 3, andit can be released only by movement ot the arm 5. This arrangement'aflords a very simple and positive lock for maintaining the door ajar.
The spring 10 is extended toward the opening 9 and isformed with a rcverscly bent, substantially S-shapcd portion l2 arm were to enter the slot, for examplcwhen 7 closing the door upon leaving the house, the
door would be locked against the rightful owner of the house, As the door isclosed, the knob at the end of the arm 5 will ride along the top of the keeper and up over the projecting tail piece 12.01 the spring. It, therefore, cannot accidentally enter the keepon hen the door is closed, pressure upon the end of the arm willbend the tail piece rdly and permit the entrance of the knob in the slot.
The advantages'of the construction wilt be apparent, and it will be obvious also that other forms and embodiments ofthe invention may be made without departing from the scope of the present invention. I The arm and the keeper maybe reversed and other changes may be made. r
What is claimed is:
1. In a door check, a slotted keeper having a channel therein, a pivoted arm having a enlarged opening at one end of the keeper, :1 spring within the channel having an S- shaped extremity projecting through the enlarged opening, and a hump in the spring remote from the opening adapted to form a dtent for the arm.
