5 Claims.

This invention relates to new and useful improvements in a protector for windows.

The invention has for an object to provide a plurality of vertical telescopic members adapted l to be extended across a window opening, and to be locked in the extended position for assisting in protecting a home or other establishment.

The invention proposes the association of an alarm with the telescopic members arranged to be set into operation when an intruder grips the telescopic members and shakes them in an effort to break in.

Still further the invention contemplates associating the alarm system with the sashes of the window so that the alarm will be set into operation when an intruder moves the sashes. It is pointed out that should an intruder cut out the glass of the sashes without moving them he will still have to pass the obstacle of the telescopic bars before he can enter the room.

Still further the invention contemplates to so construct the device that it can be applied to a window having sliding sashes or to a window of the French type.

For further comprehension of the invention, and of the objects and advantages thereof, reference 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.

In the accompanying drawings forming a material part of this disclosure:

Fig. 11 is a fragmentary sectional View on the line |I II of Fig. 9.

Fig. 12 is a schematic wiring diagram of the device.

The protector for windows according to this invention is used in combination with a window frame I0 and sashes II. 'I'he sashes Il are mounted within an auxiliary frame which is slidably supported in the frame I9 so as to be slidably vertical. Springs I3 are interposed between the top and bottom arms of the frame I0 and the top and bottom arms of the frame I2. These springs I3 serve to hold the auxiliary frame I2 in a central normal position.

The arrangement is such that when the sashes I I are moved up or down the yauxiliary frame I2 will be similarly moved, but through a much larger distance. It is the frictional engagement;k between y the sashes II and the auxiliary frame I2 which will cause the auxiliary frame to be moved. The auxiliary frame I2 will return to its normal position as soon as one ceases to move the sashes. The sashes Ii are counter-Weighted in the usual manner.

There are sash cords I4 connected with the sides of the sashes which engage over pulleys I5 mounted through openings I6 in the side arms of the auxiliary frame I2. The arrangement is such that the sashes II will maintain` various raised and lowered positions into which they are placed. A bracket I1 is mounted across the top of the frame I9. The bracket I1 lhas several lugs I8 engaged by fastening elements I9 which engage the rframe IU and serve to hold the bracket in position. A plurality of vertical fiexible telescopic members 20 are mounted. upon the bracket I'I and are adapted to extend downwards across the said window. i

Each of the flexible telescopic members 20 conf sist of a'plurality of telescopic tubes 20a, 20h, 20, etc. These tubes may be moved one within the other to assume a collapsed condition as illustrated in Fig. 1. Or these tubes may be extended to extend downwards across the window as shown inv Fig. 2. Each of the tube sections of each telescopic member is provided with cooperating grooves and pegs. A peg 2lv is mounted on each section and engages a groove 22 on an adjacent section for limiting the sliding of the sections. Therefore, while it is possible to extend the sections the engagement of the pegs with the grooves prevents complete disengagement of the sections from each other.

A bar 2# is extended across the bottom of the window. A means is provided for supporting said bar to swing slightly forwards and rearwards. This means includes a telescopic member consisting of

tubular sections

25 and 26. The bottom section 26 is mounted upon a flange 21 which is attached to the bottom of a casing 28 adapted to house certain parts hereinafter more fully described. The top telescopic section 25 is connected with the bar 24. A latch is provided for holding the

telescopic sections

25 and 26 in extended positions. This latch includes bolts 2S urged into extended positions by a spring 30. These bolts and the spring are housed in a casing 3| mounted transversely through the telescopic tube 25.

The bolts 29 are adapted to extend over the edges of the top opening in the telescopic tube 26. The top opening in the tube 26 is of a larger diameter than the outside diameter of the tube 25. Several rubber or other resilient washers 32 and 33 engage the adjacent Walls of

tubes

25 and 26, the portions within the tube 26, to flexibly hold these tubes relative to each other. The washer 32 is supported by several rings 34 fixed upon the inner wall of the tube 26. The Washer 32 engages the outside wall of the tube 25. Several rings 35 are mounted on the tube 25 and support the washer 33 which in turn engages the inside wall of the tube 26. It is therefore possible to shake the bar 24 slightly forwards and rearwards.

A means is provided for locking the extended ends of the telescopic members 20 to the said bar 24. This means includes, for each bar, a pair of pintles 36 pivotally supported at their lower ends upon a thin flange 31 extended from the bottom of the lowermost telescopic section of the telescopic member 26. A pintle 38 is used for pivotally supporting the pintles 36. Projections 39 from the flange 31 limit the extension of the pintles 36. A lock plate 40 is slidably supported beneath the bar 24 by several rivets 4| which are iixedly mounted on the bar 24 and which engage through longitudinally elongated slots 42 (see Fig. 9) formed in the lock plate 4U. The lock plate 40 is formed with a longitudinal slot 43 which is the same width as the width of the flanges 31. f

At several points along the length of this slot 43 there are branch slots 44. These branch slots are arranged at locations so that in a certain position of the lock plate 40 they will be aligned with the bolts 36. Then the telescopic members 20 are free from the bar 24. The lock plate 40 is urged into a locking position by a spring 45. One end of the spring 45 is attached upon a lug 46 projecting from the underside of the bar 24. The other end of the spring 45 engages the end 43' of the slot 43. The spring 45 therefore serves to urge the lock plate 40 towards the left, in relation to Fig. 9. A handle 41 (see Fig. 1) is mounted on the underside of the lock plate 40 and is adapted to be manually gripped to move the lock 46 towards the right to a position in which the branch slots 40 align with the bolts 36. This latter position is one in which the telescopic members 2U are now free from the bar 24.

Because of the length of the telescopic members 20, in the fully extended positions of the sections thereof, there will be sufficient flexibility to permit the bar 24 to move slightly forwards and rearwards when an intruder grips the telescopic members 20 and shakes them in an attempt to break in.

An alarm system is associated with the bar 24. This alarm system includes four contacts 56 arranged two along one side and two along the other side of the bar 24. These contacts 50 are located in the vicinity of the end portions of the bar 24. At these end portions the bar 24 is provided with projecting hook portions 24a. These hook portions 24a are adapted to engage and hook on to the extended edges of the contacts 56. The contacts 50 are resiliently supported. Each contact is mounted in a bracket 5| supported upon an inner wall of the casing 28. Each bracket 5| is formed with a slot extending from end to end through which the contact 50 is inserted. Each bracket 5| is formed with several openings 52 in its bottom face through which springs 53 are inserted. Plugs 54 are then used to close the openings 52. These springs 53 serve to urge the contacts 5U into a raised position. The hooks 24 are constructed to have front beveled edges which normally urge the contacts 50 downwards until the hook portions catch the top edges of the contacts. Then the bar 24 is latched in this position.

The contacts 50 are connected together to move up and down as a unit. There is a bar 55 connecting together the front two contacts 50. The front and rear contacts 50 are connected together at the sides by bars 56. It is therefore possible to release the bar 24 by manually moving the bar 55 downwards. Thus all four of the contacts 50 are moved downwards and the bar 24 is released. The bar 24 is formed with the hook portions 24a at the four sides of its ends. Consequently, the bar 24 may be locked by the contacts 50 in a forward or rearward position.

The casing 28 is provided with a door 51 having a lock 58 by which it is normally locked. It is when this door 51 is opened that one may move the contacts 50 and the handle 41 for the purpose previously outlined. The casing 28 is arranged immediately below the window sill 59 of the window. The window sill 59 is formed with a pair of covers 60 which are hingedly supported at their outer ends by hinges 6|. At their inner ends the covers 60 are provided with handles 62 by which they may be gripped to be opened.

The bar 24 is adapted to be moved forwards and rearwards by the auxiliary frame I2. At the bottom a vertical rack 63 projects from the auxiliary frame |2. This rack meshes with a. pinion 64 which is fixed on a shaft 65 rotatively supported. Another pinion 66 is i'lxed on this shaft. This latter pinion is engaged by a rack 61 which is mounted horizontally upon one side of the bar 24. When the sashes are moved, which indirectly cause the moving of the auxiliary frame |2, either up or down, the motion will be transmitted to move the bar 24 either forwards or rearwards so that the barl engages either the front or rear pair of contacts 50.

A means is provided for holding the sections of each of the telescopic members 20 in collapsed position. This means consists of a bar 10 which is slidably supported in a horizontal position in brackets 1I mounted upon the Window frame I0. The bar 1G is provided with a plurality of iingers 12a, 12b, etc., of varying lengths. These fingers selectively engage beneath the lowermost sections of the telepscopic members 2D. A pin 13 is mounted upon the bar 10 and is engaged by the forked end 14a of a lever 15 which is pivotally mounted intermediate of its ends by a pintle 16. The lever 15 may be pivoted to move the bar 10. The fingers 12s, 12b, etc. are so located in respect to the telescopic members 20 so that as the bar 10 moves, the finger 10a will move free from its telescopic members 20 to drop the sections thereof. Then as the bar 10 continues to be moved the linger 12b will move free of its telescopic member 28 to drop the sections thereof. In this manner each of the telescopic members 20 will be released in succession one at a time. There is suficient space between the fingers 12a, 12b, etc., so that the lingers do not interfere with the extension of any of the telescopic members 20. The telescopic members 28 may also be released and lowered in any other suitable manner.

The alarm system includes a small alarm 'Vla intended to be located within the premises, and a large alarm 'Hb intended for exterior use. This large alarm is arranged within a tubular casing 'l1 extending to the exterior of the house or establishment, through the wall 18 thereof. A shield 19 is extended across the tubular member 11 and is supported in position by several braces 80. The arrangement is such that the sound from the alarm 1lb may pass through the space beneath the shield 'I9 to the exterior. 'I'he contacts 50 are y connected with a lead 8| which includes in series the alarm lle, a hand switch 82, and one terminal of van electric supply 83. The other terminal of the electric supply is connected by a lead 84 to the bar 24. 'Ihe alarm 11b is included in a circuit 85 shunted across the leads 8| and 82. The circuit 85 is arranged to be controlled by a hand switch 86.

The operation of the device is as follows:

Normally, the device is as shown in Fig. l. In this condition the window sashes are unobstructed and the window sill is closed by the covers 6D To place the device into operative condition it is rst necessary that the covers 6U be lifted to the positions shown in Fig. 2. Then the bar 24 is lifted from its lowered position, shown in Fig. l, to that shown in Fig. 2. When the bar 24 is lifted up the

telescopic tubes

25 and 26 will be extended. They will be held in extended position by the bolts 23.

'Ihen the lever l5 is moved to drop the telescopic members 20 one at a time. The lower ends of these members are -iorced into the slot 43 of the lock plate 4t. The bolts 35 of each of these members will open up beneath the plate and so the members will become locked to the bar 24. The uppermost tubes of the telescopic members 2U, that is the tubes. 20e, are locked to the bracket l1 by punchings 2B' or any other similar means. Because of the pins 2l and the grooves 22 it will not be possible to turn the sections of the telescopic members 20 relative to each other. Therefore, the bolts 36 will maintain locked po sitions transversely across the slot 43. The switch 82 or the switch 86 is then closed, or both switches closed, depending upon Whether it is desired that one alarm operate, or that the alarms operate simultaneously.

Should an intruder desire to break in and move the sashes H the alarm will be set into operation for the reason that motion of the sashes Il will be transmitted to the auxiliary frame I2, and then by reason of the rack 63 the

pinions

64 and 66 and the rack 61 to the bar 24. The bar 24 will then move forwards or rearwards and the hooks 24a lock on to the front pair or the rear pair of contacts 50. This closes the alarm circuit and the alarm will start ringing.

In the event that an intruder does not move the sashes I I, but cuts out a portion of the Window glass, then he will encounter the vertical telescopic members 28. These membersfwill stop his entrance. Should he shake these members in an attempt to break them down the bar 24 will be moved either forwards or rearwards and the hook portions 24a will engage the contacts 50 and.

again the circuit .through the alarm will be closed.

The burglar alarm may be set to an inoperative position by a person capable of opening the lock 58 and the door 5l. This person may now reach the bar 55 and pull down on the bar to move the contacts 5c downwards. This releases the hooks 124*i andthe bar 24 will return to a central inoperative position. The various telescopic members 2l] may be disconnected from the bar 24 by gripping the handle 41 and pushing the lock plate lll laterally so that the branch openings 44 align with the bolts 36. The bolts 36 may now pass through these openings and the telescopic members are free.

It is to be understood that this arrangement may be installed in finished buildings. or built in any new building and used with the usual sliding window sash or any swing type window, by connecting the locking handle of the window to the telescopic members 20, in any suitable manner.

It is also to be understood that the telescopic members may be either round, square, or any other shape in cross section, with or without any guiding grooves 22 and ornamented to harmonize with the surroundings. The telescopic tubes in the telescopic member 20 are of suitable length and in the closed position causes no obstructions and are hidden from sight,

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction 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.
