Description

J 5, 1951 I A. R. CHRISTIE 2,555,915 I OPEN wmnow GUARD Filed April 3, 1946 Patented 'June 5, 1951 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to an open window guard structure utilizing a wedge principle, the guard being applied to the upper sash of a window to prevent a partially open lower sash from being forced farther open.

An important object of the invention is to provide an open window guard having a wedge membermovable to operative and inoperative positions. In the operative position of the wedge member a sloping wedge face thereon extends upwardly and outwardly beyond the plane of the lower window sash, whereby the lower sash will be limited in its upward movement. The structure is so designed that when the wedge member is moved to its inoperative position, the wedge face thereon will be located in a plane substantially parallel to the plane of the lower window sash, whereby the lower window sash may be moved past the window guard to fully open position if so desired.

Another object of the invention is to provide an open window guard wherein a wedge member is mounted for pivotal movement on the upper sash of a window and may be moved to operative and inoperative positions. Yieldable means is also provided bearing outwardly against the under side of the wedge member to maintain it in a plane substantially parallel to the lower window sash when the wedge member is in its inoperative position.

A further object of the invention is to provide an open window guard which includes both a base member and a wedge member, and wherein the wedge member is loosely mounted on the base member for pivotal movement to operative and inoperative positions on the upper sash of a window. I

Still another object is to provide an open window guard wherein a wedge member is loosely and pivotally mounted on a base member which, in turn, is secured by means of a single fastening means to the upper sash of a window. The wedge member is so constructed as to be rigidly supported in its operative position, but may be easily moved to its inoperative position where yieldable spring means urges the wedge member to a position where the wedge face thereof is substantially parallel to the plane of the lower sash of the window, whereby the lower sash may be moved upwardly past the wedge member.

Other objects and advantages of the invention will become apparent upon reading the following description taken in conjunction with the accompanying drawing in which:

Fig. 1 is a fragmentary elevational view of a portion of a window showing the invention applied thereto in operative position;

Fig. 2 is a fragmentary vertical sectional view taken substantially along the plane of line 22 of Fig. 1 showing the open window guard in side elevation;

Fig. 3 is a view similar to Fig. 1 but showing the wedge member moved to its inoperative position;

Fig. 4 is a view similar to Fig. 2 showing the wedge member in its inoperative position and in side elevation;

Fig. 5 is a horizontal sectional view taken substantially along the plane of line 5-5 of Fig. 1;

Fig. 6 is a vertical sectional view taken sub stantially along the plane of line 6-6 of Fig. 1; and

Fig. 7 is a perspective view of the base member.

Referring now more particularly to the drawing, a typical form of window is illustrated wherein the upper sash is indicated by the numeral I andthe lower sash by the numeral 2. The open window guard of the present invention is adapted to be applied to one of the vertical side members of the upper sash and includes a base member 3 and a wedge member 4.

Referring for the moment to Fig. '7, it will be noted that the base member 3 includes a, locating bend 5 in the form of a longitudinal inwardly turned flange along the edge of the base member. This locating bend 5 is adapted to be placed against an edge of the vertical side member of the upper window sash. A positioning bend 6 in the form of a forwardly extending flange is located along a diagonal edge of the base member, against which the lower end of the wedge member will come when in operative position, thereby acting as a stop or positioning means for the wedge member. An opening I is provided for the reception of fastening means such as a nail or screw, and yieldable means for hearing outwardly against the wedge member 4 is preferably provided in the form of an integral upstruck portion 8. This yieldable member is struck upwardly from the face of the base member 3.

The wedge member itself includes a wedge face I I, a downwardly extending side face I2, and a downwardly extending end face I3. A countersunk opening I4 at the lower part Of the wedge face I I is adapted to receive fastening means such as the screw I5. The screw I5 constitutes the means by which the wedge member and the base member are both secured to the upper window sash. It should be further noted that the screw I5 loosely supports the wedge member 4 for pivotal movement between its operative position, as shown in Figs. 1 and 2, and its inoperative position, as shown in Figs. 3 and 4.

When the wedge member is in its operative position, the edges of the downwardly extending faces I2 and I3 bear solidly against the base member 3 to thereby rigidly support the wedge member in its operative position.

The guard member can not be reached from the outside of the window, but can be easily released and moved to its inoperative position 3 merely by slight force by the fingertips. This is an advantage because the guard may thereby be released, for example, when it is necessary to reach through Venetian blinds.

When the'wedge member 4 is moved to its inoperative position as shown in Figs. 3 and i,

it will drop downwardly by gravity because ofthe loose connection with the base. El e construction of the wedge member is such that when it falls downwardly to its inoperative position, the end of the wedge face H thereof would ordi: narily extend outwardly beyond the plane of the lower window sash. For this reason yieldable means in the form of the spring member 8 is adapted to bear outwardly against theunder side oi-the. wedge memben'whereupon the wedge face H will be held in a substantially vertical plane parallel to the plane, of the lower window sash.

' It will also be noted that in this position of the wedge member it is held somewhat semirigidly, or yieldably, so that if the wedge faee ll should extend slightly beyond the inner edge of the lower window sash it may easily yield and permit the lower window sash to move upwardly past the window guard.

From the foregoing description it will be evidentjthat a novel construction has been provided in the present invention and applied to an open window guard, which is simple in its operation. The entire device is easy to install because of the single fastening means adapted to secure both the base member and the wedge member in place. The structure is designed for economical manufacture.

Changes may be made in the form, construction and arrangement of parts from that disclosed herein without in any way departing from the spirit of the invention or sacrificing any of the attendant advantages thereof, provided, however, that such changes fall within the scope of the claims appended hereto.
