Patented Sept. 27, 1932 i warren stares GEORGE EATON, 0F GEEVELAND, OHIO, ASSIGNOR T0 MAY 0. EATON DOORCHECK Application filed July 10,

This invention relates to an improved form of door check.

The object of the present invention is to devise a door check which is of comparatively simple structure capable of easy manufacture ata comparatively low cost and at the same time possessing an extremely high degree of efiiciency.

The present invention contemplates form-- ing the door check as an integral one-piece body of spring metal which may be formed by the stamping process and as a result may be marketed at a low price.

This device comprises a wedge portion which is adapted to be inserted beneath the bottom edge of the door and to extend in a plane corresponding to that of the door, and side bowed portions which are adapted to afford spring force for holding engagement of the middle wedge portion with the bottom edge of the door and at the same time to extend above the bottom edge of the door for engagement therewith so as to prevent accidental dislod 'ment of the door from the middle wedge portion of the door check.

According to the prior art, there have been devised numerous door checks which are applied from the front thereof and which as a result extend out from the plane of the door so as to constitute more or less of a hindrance. Also, this old type of door check serves as a means of maintaining the door against movement in only one direction.

According to the present invention, it is contemplated that the door check will extend in substantially the same plane as the door so as to be practically out of the way and at the same time the manner of engagement of the door check with the door and its relative position with respect thereto will serve to prevent m vement of the door in either direction.

Fig. 1 is a perspective view of my device; and Fig. 2 is a perspective view illustrating its application to a door.

Other objects will appear from the following description and claims when considered together with the accompanying drawing.

It is to be understood that the present disclosure is merely for purposes of illustration 1931. Serial No. 550,018.

and that other modifications and variations may be devised without departing from the spirit of the present invention as herein set forth and claimed.

As will be seen in the accompanying drawfront ends of the bowed portions are jointed laterally to the front end of the middle wedge portion 1 so that the entire front end of the device is of a flat or Wedge form. The middle wedge portion 3 extends upwardly at an angle and is of flat form'throughout substantially the entire extent thereof except for the eX- treme rear end portion which is formed into a curved portion 1 which may be depressed by the thumb of the user for applicationor removal of the same.

The side bowed portions 4 are ofa curved form and are joined together at their rear ends so as to provide the portion 2 for engaging the floor. This rear floor-engaging portion is slightly curved upwardly and rear- This device as herein disclosed wardly for the purpose of afi ording a fingerengaging portion. As will be seen from the drawing, the device is open between the bowed portions and the space therebetween permits ready and full depression of the middle wedge portion so as to permit application or removal of the device to or from the door.

This device is so constructed and arranged that even before application thereof to the door and without depression of the wedge portion, the side portions extend somewhat above the plane or wedge portion. Then upon application ofpressure to the portion 1 the wedge portion will be depressed and the bowed portions 2 will be somewhat com-V pressed towards straightened position so as to lessen the angle of the wedge portion and thereby permit full insertion of the wedge portion beneath the bottom edge of the door.

The width of the wedge portion corresponds substantially to the width of the bottom edge of the average door so that when placed in such operative position with respect to the Ti door, the bowed portions 2will extend above the bottom edge of the door and in close proximity thereto. I

The bowed portions 2, therefore, perform a two-fold function; first, they supply the tension by which the wedge portion may be inserted in position beneath the door and efiioiently held in such operative position by the spring force thereof. Second, the bowed portions 2 serve as a means of engaging the two sides of the door and maintaining the same against accidental disengagement from the door check when placed in holding position.

Upon application of this device to a door, the wedge portion can be depressed by the thumb and the device can then be slid under the door by the same hand. As indicated in Fig. 2, the device will preferably be grasped by the thumb engaging the portion 1" and the index finger of the same hand engaging under the curved portion 2. In this way, any tendency of the device to stick in its engagement with the floor in this manner will be also facilitated by the curved rear portion 2 which rests upon the floor. Also during both insertion and removal of the device, the curved form 1 at the rear end of the wedge portion not only serves as a rest for the thumb during depression thereof but, if so desired, may serve also to accommodate the index finger, upon the under side of such curved portion 1. Thus, if so desired, the rear end 1 of the wedge portion may be conveniently gripped by the thumb and finger during both insertion and removal of the device. Also, there is: provided sufficient space between the rear end of the wedge portion and the rear joined ends of the bowed portions so as to accommodate the fingers of the hand during such insertion and removal of the device.

In the manufacture of these devices, they will be first stamped out of metal into the form desired and then tempered so as to obtain the proper degree of resiliency for the purpose herein set forth. This process, as will be obvious to those who are skilled in the art, is comparatively simple and inexpensive and makes possible greatquantity production.

Thus, it will be seen that all of the objects as above specified have been accomplished in the present specification and other advan tages in addition to those herein specified will readily suggest themselves to those who are familiar with the art to which the present 7 invention relates.

What I claim is:

1. A door check comprising a wedge portion adapted to be inserted under the edge of the door and to extend in the same direction as the door, and a side portion connected to the wedge portion and adapted to extend above the bottom edge of the door and engage the side thereof so as to prevent disengagement of the door from said wedge portion,

said side portion being formed as a bow of spring metal adapted to be compressed by engagement with the floor as the wedge portion is wedged under the door and to thereby afford means of holding the wedge portion in effective position.

2. A. door check comprising an integral one-piece body of spring metal having an inclined middle wedge portion adapted to extend beneath the edge of a door in a direction corresponding with the plane of the door, and side bow portions adapted to bear at their ends upon the floor so as to provide spring engagement for the wedge portion and also to engage the side faces of the bottom portion of the door and thereby prevent lateral disengagement of the door from the wedge portion.

3. A door check comprising an integral one-piece body of spring metal having an inclined middle wedge portion adapted to extend beneath the edge of a door in a direction corresponding with the plane of the door, and side bow portions which are joined laterally to the front lower part of the wedge portion and are joined together at the rear thereof, the front end of the entire door check being adapted to bear upon the floor beneath the door, and the rear joined end of the bowed portions being adapted to bear upon the floor outside of the plane of the door, and said wedge portion terminating rearwa-rdly in an upwardly extending finger portion which. may be depressed for spreading the bowed portions preparatory to insertion and re-' moval of the device, said how portions being adapted to provide spring engagement for the wedge portion and also to engage the side faces of the bottom portion of the door so as to prevent lateral disengagement of the door from the wedge portion.

In witness whereof, I hereby affix my sign ature.

GEORGE EATON.
