13 Claims.
This invention relates to new and useful improvements in heat saving shields for windows.
The invention contemplates a new heat saving shield for a window, characterized by a stiff board such as cardboard, or other pasteboard, and other materials, adapted to extend across the inside dimensions of a window frame and formed with a back panel and flexibly connected side panels obliquely extending forward against the sides of a window frame and associated with a stiff strip adapted to be mounted'across the window frame and to bear against the back panel for holding the board in position."
The new shield" for windows is particularly intended to reduce the radiation of heat through the window and window panes, as a war emergency measure to save heat. Of course the new shields are opaque and may be used for blackouts.
Still further the invention proposes providing the edges of the stiff board with binding material which will assist in preventing or reducing the circulation of air around the shield.
The invention proposes various modified forms of shields, each of which embodies the essential features of this invention. In one form certain fastening elements are proposed for'assisting in and of the objects and advantages thereof, referv ence will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.
vided-with a heat saving shield constructed in accordance with'still another form of this invention, 7
Fig. 9 is a horizontal sectional view taken on the line.9 9'of Fig. 8. i
Fig. -10 is another elevational view of a window provided with an air shield constructed in accordance with still another form of this invention.
Fig. -11 is a vertical sectional view line li-ll of Fig. 10.
Fig. .12 is a similar view to Fig. 9 in accordance with another modified form of the invention.
Figs. 13 to 17 are similar views to Fig. 3 but illustrating other modified forms of the invention.
taken on the Fig 18is a similar view to Fig. 5, illustrating another form of the invention.
In the form of the invention illustrated in Figs. 1-5 inclusive, the heat saving shield includes a stiff board I! for extending across the inside dimensions of a window frame such as indicated by'reference numeral Hi. This stiff board I! has a back panel I4 and flexibly connected side panels In the accompanying drawings forming a matebinding and the edge of the stiff board.
Fig. 4 isan elevational view of the air shield in a collapsed condition.
Fig. 5 is a sectional view taken on the line 5-5 of Fig. 4.
.This strip i6 may be constructed from a thin strip of wood. Fastening elements are provided for holding the strip it as desired. As disclosed, this fastening means includes a fastening element- I! connected between the center of the strip l6 and the center ofthe board. Thus, the strip I6 is not only connected with and supported on. the board II, but itmay pivot to a vertical position, as for example shown in Figs. 4 and 5. However, the strip l6 may also .be sold unattached.
The window frame I3 is provided with pins I! or other abutment behind which the ends of the strip iii are engaged. Thus, the strip l6 squeezing against the back panel l4 holds the board in position. The resiliency of the connection between tre panels l4 and I is depended upon to cooperate with the strip IE to hold the board. Another pin I 9 is driven into the base portion of the window frame l3 and engages against the bottom of the board l2, assisting in holding it in position.
Binding strips are attached to the edges of the board i2. Prefe ably, these binding strips are of cloth or'o'ther soft material. They are attached by 'lmes of stitches 2|, or in any other way. They engage against the window frame l3 and serve to reduce the circulation of heat and air through the window. When the air shield is not in use it may be folded as illustrated in Figs. 4 and 5 and stored away.
In Figs. 6 and '7 a modified form of the invention has been disclosed which is similar to the prior form, distinguishing merely in the way in which the stiff strip I6 is supported. In this form of the invention one end of the'stiff strip I6 is pivotally connected by a pintle 22' with a fastening element 23 mounted on the side of the window frame. The other end of the strip I6 engages behind a pin 24. Another pin is mounted on and projects from the strip 5 and rests upon and is supported by the pin 24. With this construction the strip It may be pivoted to an' open position about the pivot 22.
In Figs. 8and 9 another modified form of the invention has been disclosed which is very similar to the first form, distinguishing merely in the fact that the stiff board I2 is constructed with a the invention is disclosed which primarily distinguishes from the prior form in the fact that the air shield includes a stiff board l2 formed from two sections. There is a top section 28 and a bottom section 29. These sections are releasibly connected with each other by a staple 3 0 engaged through the overlapping adjacent edge portions. The top section '28 is supported in position by a strip l6 engaging against its back panel. This strip I6 is pivotally connected by av pintle 22 with a pin 23 mountedon the window frame. The strip l6 has another pin' 25 resting on a pin 24 on the other side of the window frame. The bottom section 29 is illustrated supported in position by a stiff strip I6 which is pivotally mounted at its center by a pintle l8 upon the back panel 'of the section; The ends of the strip l6 engagefbehind pins I! mounted on the sides of the window frame. In other respects this form of the invention is similartothe previous form.
In Fig. 12 the board i2" is divided into two equal sides I5 by the vertical central crease. In other respects this form of the invention is similar to the previous forms.
In Fig. 13 part of the binding strip 20 is stitched within the edge of the panel I5. In Fig, 14 the binding strip-20 is stitched at 2| to the side'of themember l5.
In Figs. 15 and,16 the panel It is illustrated with a folded edge l5 andthe binding strip 20 is shown to be fastened tothe side of the panel l5 by stitchesll. .In Fig. 17 the panel 15 is shown with afdouble fold I 5 and the binding strip 20 is shown to be stitched at 2| to theside of the panel I5". 7
In Fig. 18 both side panels I5 are shown to be folded'on one side of the back panel 14.
It is to be understood that this heat saving shield may be of any shape, size and material and that the retaining strip I6 may hold the heat saving shield in position without any holding pin, or by a string stretched between the sides of the window frame.
While I have illustrated and described the preferred embodiments of my invention, it is to 1 be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
