PROTECTIVE DEVICE FOR WINDOWS Filed June 5, 1952 Patented Feb. 6, 1934 UNITED `STATES .PATENT OFFICE This invention relates to protective guards for store windows.

One of the objects of the invention is in the provision of a protective guard for store windows which guard may be placed either on the outside or inside of the window.

Another object lies in the provision of a protective guard for store windows, the same being operated by the storekeeper in such manner that the guard Vprotects either the inside or -outside of the window.

Still another object lies in the provision of a protective guard for store windows which is carried in a track forming a part of the guard mechlI anism, said track permitting the guard izo-entirely surround the store windows, irrespective of their shape or angular position.

Yet another object lies in the provision yof a protective guard for store windows and the like,

said guard having a plurality of intermittently `disposed solid double linksand pivotal links, the same being carried in upper and lower track members as to permit ease of movement of the guard, `either from a collapsed to an expanded position or vice versa.

A still further object is `in the provision of a protective guard for store windows `and the like, the guard itself being collapsible in nature and being made up of a plurality of solid and pivotally connected links, said .links having Vtheir upper ends carried in a track in such manner that the track forms a part of the vguard mechanism, the track further being provided with means which permits the collapsibility of the entire guard in a minimum of space, and with a minimum of effort.

An additional object lies in the provision of a flexible protective guard for store windows and the like, the same being capable of securement to the windows in a manner to surround corners or any unusual shaping of the window, said ilexible protective guard being carried in a track forming a part of the guard, the guard itself comprising a series of pivotally connected guard vmembers disposed vertically and carried in a rolling manner within the track so as to permit ease of movement by the operator or storekeeper, whether upon the inside or outside of the window, there being also provided an automatically operating cam mechanism in connection with the track which permits collapsibility of the guard vin a nonexposed and minimum space.

Other objects will appear in the following speciiication taken in connection with the annexed drawing, in which Fig. 1 is a plan view, showing in a diagrammatic manner the mounting of applicants protective guard, either upon the inside or outside of variously fashioned store windows;

Before referring specifically to the drawing for a detail description of applicants invention, it might be stated that the present applicant has devised Aa protective guard of a iiexible and collapsible nature for store windows of any size or structural arrangement. In other words, by virtue o-f the disposition of the iiexible kguard and lmanner of supporting and carrying same in upper andlower tracks, the guard may be used to surround store windows `either upon the outside or upon the inside. By using a protective guard of this character, the storekeeper may `operate the guard without ldisarranging his display in the Window and the guard has the improved feature of being readily Aand easily moved to a guard or to a collapsed position. Further, it will be found that by the peculiar larrangement of double welded or solid links in connection with intermittent pivotal links, the guard is not only strengthened to a great degree, but further, when this combination of links is operatively connected with the upper and lower tracks, the guard ceases to be a exible and `'collapsible guard unit, but is a protective mechanism which is supported not only from above and Abelow and at either end, but also between the tracks as well.

view taken on the rIhe device has obviously for its more important purpose the protection of store windows, and the same is sufficiently flexible to be applied to windows, irrespective of their curved or rectangular shape or other form.

In Fig. 7 of the drawing, a sub-combination of elements has been shown, wherein the dual solid links and intermittent pivotal links are carried in an upper and lower track in a more simple manner for the purpose of covering a dat opening or closure member, whether a door or a window.

Applicant again points out the fact that be-V cause of the arrangement of the guard in connection with the track, same may be moved by the operator with a minimum of effort and when Figs. 4, 5 and 6 are viewed, it is quite apparent that by the special cam arrangement used in connection with the track, an automatic collapsing of the guard into a minimum of space is effected.

Referring specifically to the rawing, in Fig. 1 is shown in diagrammatic manner the conventional rectangularly shaped frame of a store window 10. In this figure the store window is shown in various forms and the track forming a part of applicants guard and designated 11 is shown not only `on the inside of the window but also on the outside. The upper track, which has been designated 11a is similar in every detail to the lower track 11. The track itself is adapted to be secured to the structural portion of the building by means of plural clamps or bracket members 12. Obviously, the manner of attaching the track to the building could be accomplished in a number of ways without departing in the least from the spirit of the invention.

The tracks 11 and 11a are formed of rectangularly shaped steel portions, the same being apertured in the manner shown at 13.

Referring specifically to Fig. 9, there is found therein a detail disclosure of the manner of carrying the guard member within the tracks 11 and 11a. In other words, certain of the guard links are secured as at 14 to dual roller members 15, the same being carried, as shown clearly in Fig. 9, within the upper track 11a. By hanging the links, or rather the protective guards, from an elevated position, it is not necessary that the lower ends of the links be similarly carried in a roll type manner, although of course dual rollers might just as well be connected at the lower end.

It will be noted that the guard itself is made up of a plurality of links having different description. In the iirst place,

vertical guard members

16 and 17 are connected in a fixed or solid manner, as shown in Fig. 10 rof the drawing. These links are connected to the dual straps 18 and 19 which are welded as: at 20 and 21 to the befofe mentioned

links

16 and 17.

Referring to Fig. 2, it is found that adjacent guards 16 lie horizontal pivotal connecting straps 22 which connect adjacent dual and solid vertical guard members 23 and 23a with similarly formed and before mentioned duel

vertical guard members

16 and 17. Applicant has merely described the upper solid connection and pivotal links although it is quite apparent that this link connection is carried out throughout the entire guard and that the lower connecting mechanism is exactly the same as shown at the top.

In Fig. 2, it will be noted, however, that additional guard mechanism such as the

members

24 and 25 have been secured tothe before mentioned vertical guards and link mechanism, merely for additional protection. V.The same are obviously secured to the

members

16, 17 and 22 in exactly the same manner as above described. Applicant might carry out the description of the intermittently disposed dual solid links and the adjacent pivotal links, but it is believed that in view of the above description same is quite apparent.

It will be noted that the

vertical guard members

16 and 17, and 23 and 23a all have their upper and lower ends carried in and protected by the before mentioned upper and lower tracks 11 and 11a. A few of these links have the roller members 15 attached thereto and act as a means for supporting the flexible or collapsible guard within the tracks. However, at all times the guard is secured within the tracks and is carried thereby in such manner that there is a support for the vertical members not only at either end but also at the top and bottom. Further, the use of the dual solid links in connection with the pivotal links greatly assists in strengthening the flexible guard mechanism throughout.

In Fig. 7 of the drawing a modification has been shown of applicants guard, wherein same is used for covering a flat space. In this instance, the upper and lower tracks 26 and 27 are receiving places Q for the solidly connected

vertical guards

28 and 29, which are. pivoted to adjacent similar portions byl means of the plural pivoted connecting links 30.

In Figs. 7 and 8 also has been sho-wn, as previously noted, a modification of applicants collapsible guard, wherein there is not shown exactly similar track mechanism for supporting the guards in a rolled manner. However, it is noted that the same character lof dual solid guard members are used in combination with the pivoted links.

In Figs. 4, 5 and 6, the manner of collapsing the pivotal dual guard members in a minimum of space is believed to be clearly shown. In these figures it will be noted that the track is broken in the manner shown at 31 and that a guard member 32 is disposed adjacent this track opening. A pivoted cam member is shown at 33, said member being normally held in the position shown in Fig. 6, wherein a spring 34 abutting one side of the cam normally holds the cam in the position shown in this figure. It will be noted in Fig. 6 also that the lower ends of the vertical guard members will pass the cam 33 when said cam is in the position shown in this figure. However, as the lower end of the guard continues its normal movement along the track to a collapsed position, that member strikes the cam surface 35 in the manner shown clearly in Fig. 5, whereby the throw-out end 36 of the cam is carried to a position clearly shown in Fig. 5 and to such a position as to eject the following guard member through the track opening 31. However, the passage of this guard portion through the track opening, il,

taken in connection with the iinal movement of the previous guard element beyond the cam 33, permits the spring 34 to again depress the cam to the positionshown in Fig. 6, whereupon the following depending guard member will continue in normal manner along the track, said member finally moving the cam to the position previously mentioned in Fig. 5, whereupon the automatic throw-out portion 36 will again eject the following 4guard member through the track opening. Thus,

it is found that the collapsing of the protective guard operates automatically first to carry one of the guards along the track and thereupon and automatically to eject the next guard through the track opening, while'the following guard member iic 'izo

continues its normal travel. Thus, with an automatic operation the guard members are collapsed to such a position as to occupy a minimum space, as shown in Figs. 4, 5 and 6 of the drawing.

With respect to the operation of applicants device, itis believed from the above description taken in connection with the drawing that it is quite obvious that the guard may be operated either upon the inside or the outside of a show window of any size, shape or form.

It is believed further to be apparent that the guard is made up of a series of solid dual vertically disposed guard members connected by intervening pivotal links; that the collapsible guard is carried in an easy manner in the track by virtue of the roll supports at the top; further, that the use of these dual solid vertical guard members and their manner of support in both the upper and lower tracks presents a formidable protective guard. Finally, the collapsing of the guard to a position where same will occupy a minimum space is believed clearly understood from viewing Figs. 4, 5 and 6 of the drawing, wherein the operation of the automatic cam activated by the upwardly and downwardly projecting ends of the guard members is clearly set forth. The action of one of the guards controls the direction of movement of the cam at one time while the following depending or upwardly projecting end of the guard operates in a reverse direction to accomplish the collapsing operation.

With respect to Figs. '7 and 8 of the drawing, ihe operation of the collapsible guard when used upon a window in a single plane or across an enclosure such as a door or the like, is believed clearly set forth.` The same character of dual solid vertical guard members with the intervening pivoted links and the manner of collapsibility is believed to clearly disclose the fact that applicants device may be used as a protective medium without the use of the upper and lower tracks and the roller mounting of the guard therein and the automatically operating cam for collapsing same.

Further, with respect to the manner of securing applicants collapsible guard to the framing structure surrounding the window, it is contemplated that at the end of the guard wherein same is capable of being collapsed in a minimum space,

the guard shall be attached securely to the surrounding framework and that at the oher end to which same is adapted to be extended or expanded, same shall be connected to the framework by any character of locking mechanism such as a padlock or the like. As a matter of fact, it is immaterial Whether the guard is secured in a detachable or locked position at either end thereof.

What I claim is:

1. A protective device for windows comprising in combination upper and lower track portions, a

series of xedly secured, dual vertical guard members having their upper and lower ends carried in said tracks, intervening pivotal connections for said guard members and mechanism automatically operating in connection with said track members for automatically collapsing the guard in a minimum of space.

2. A protective device for Windows including in combination upper and lower track mechanism, a plurality of vertically disposed guard members having their upper and lower ends carried in the before mentioned track, means for pivotally connecting said guard members together said track operating to prevent pivotal movement when the guard members are extended and mechanism operating in connection with the track operating to induce pivotal movement of the guard members when the same are moved into contact with said mechanism thereby permitting collapsibility of said guard members in a minimum of space.

3. A protective device for windows including in combination upper and. lower track mechanism, a series of vertical guard members having their upper and lower ends extending into said track mechanism, means for pivoting the vertical guard members together said track operating to prevent pivotal movement when the guard members are extended, means for supporting the series of guard members in a rolling manner in the tracks to permit ease of movement therein, and mechanism operating automatically to induce pivotal movement of the guard to permit collapsing of the series of guard members in a minimum of space.

4. A protective device for windows including in combination upper and lower track members, a series of xedly secured, dual vertical guard members having their projecting end portions intermittently supported and controlled by the upper and lower track mechanism, and means for pivoting the said dual vertical guard members together in a manner to permit collapsibility thereof.

5. A protective device for windows including in combination upper and lower track portions, a series of xedly secured dual guardmembershaving their upper and lower ends carried in said tracks, pivotal link connections between said dual guard members and means for automatically collapsing said dual guard members in a minimum of space, said means including cam members connected to the tracks and controlling an opening therethrough in a manner to automatically and intermittently control the movement of succeeding guard members either through the opening or along the track.
