Dak. Application October 14, 1942, Serial No. 462,019

3 Claims.

The present invention relates to new and useful improvements in door checksdesigned primarily for use in connection with screen doors to prevent injury to the door by strong wind and embodies the provision of an equalizer member connected to the door and to a stationary part of the door frame by coil springs to produce a gentle closing movement of the door to prevent undue banging thereof.

A further object is to provide a device of this character of simple and practical construction, which is eificient and reliable in performance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like a parts throughout and in which- Figure 1 is a view in elevation showing the door check in position with respect to the door.

Figure 2 is a sectional view taken substantially on a line 2-2 of Figure 1.

Figure 3 is a similar view and showing the door in a partially open position.

Figure 4 is a sectional view through the equalizer member taken substantially on a line 4-4 of Figure 1.

Figure 5 is a plan view of the blank from which the equalizer member of hollow construction is formed and Figure 6 is a top plan view of a modified form of equalizer.

Referring now to the drawings in detail and with particular reference to Figures 1 to 5, inclusive, the numeral 5 designates the equalizer member generally which is of hollow substantially triangular form and constructed from a blank sheet of metal as shown to advantage in Figure 5 of the drawings.

The blank includes a central portion 6 which forms the top of the equalizer member, the top being of substantially triangular form and pro- J'ecting from two of the sides of which are the flaps I and B folded along the dotted lines 9 to form the sides of the equalizer member. At the other side of the triangular central portion 6 is a flap H which is folded downwardly along the dotted lines I l to close the front end of the member.

At the rear ends of the flaps 'l and 8 are the tongues 12 which are bent to form the bearings I3 positioned in aligned relation to receive a hinge pin l4 secured to the side of a door frame 15 At the outer ends of the flaps I and 8 are tongues I6 bent to form eyes indicated at l! for attaching one end of a pair of coil springs l8 and I9, respectively, thereto.

As shown to advantage in Figure 4 of the drawings, the eyes H are bent inwardly against the end portion In to secure the latter in position.

The screen door is designated at l9 to which the other end of the coil spring I9 is attached while the other end of the coil spring 18 is attached to a stationary part of the door frame by means of a screw eye 20.

The outer end of the equalizer member 5 is rounded to eliminate the formation of any sharp edges that might contact the spring members It and I9 during the opening and closing movement of the door.

In the modified form of the invention illustrated in Figure 6 of the drawings, the numeral 2| designates a substantially rectangular hollow or solid block preferably constructed of wood and having one part of a hinge member 22 secured to an inner corner thereof for pivotally attaching the same on the hinge pin [4.

At the outer end of the block are a pair of screw eyes 23 and 24 adjacent the respective outer corners thereof for attaching the spring members 18" and I9 thereto in a manner as heretofore explained.

By connecting the spring members l8 and 19 to the equalizer member 5 in a crossed relation, it will be apparent from an inspection of Figures 2 and 3 of the drawings tension of the two springs cooperate substantially equally during the opening and closing movement of the door so as to produce a gentle closing movement thereof.

It is believed the details of construction, advantages and manner of use of the device will be readily understood from the foregoing without further detailed explanation.

Having described the invention, what is claimed as new is:

1. A door closer comprising a member pivoted to a door supporting structure adjacent the hinged edge of the door, and a pair of substantially duplicate expansible members attached at one end respectively to the door and to a stationary structure said expansible members being arranged in crossed relation and having their other ends attached in spaced crossed relation to the free end of the first-named member.

2. A door closer comprising a member pivoted to a door supporting structure adjacent the hinged edge of the door, and a pair of substantially duplicate coil springs attached at one end respectively to the inner side of the door and to a stationary structure inwardly of the door and having their other ends crossed and attached to spaced portions of the free end of the member.

3. A door closer comprising an equalizer member constructed from a blank sheet of metal in cluding a central portion having flaps foldable angularly to the central portionto form a pair of 10 substantially opposed sides and an end wall,

tongues on one end of the side flaps rolled to form alined hinge eyes adapted for receiving a hinge pin carried by a supporting structure, inturned eyes on the other ends of the side flaps overlying the end wall to retain the latter in folded position, and springs attached to said last-named eyes for connection respectively to a hingedly mounted door and to a stationary part of a door jamb in which the door is mounted.
