16 Claims.

The invention relates to a so-called burglar proof closure for doors and windows composed of a plurality of interchangeable parts which include a marginal frame and a. metallic knockdown grill structure composed of bars and coupling members of a suitable metal, all of which are capable of assembly to fit door and window frames of different dimensions.

The main object of the present invention is to provide a grill structure composed of bars and coupling members wherein the composite bars or rods are so interlocked with each other within the coupling members as to obtain two primary advantages, one thereof being to provide a structure wherein the coupling members are of the smallest possible dimensions relatively to the dimensions of the bars associated therewith so as to exclude as little light as possible and at the same time provide the maximum length of bearings of the end portions of the bars within the couplings as to prevent any one of the bars from being withdrawn from a coupling without effecting breakage of said bar within the coupling or first efiecting breakage of a companion bar with which the same is interlocked.

A further object of the invention is to provide within the marginal frame of the structure a means whereby any axially aligned set of bars of the structure may be placed under tension or compression at will. 7

Suitable embodiments of' the invention are illustrated in the accompanying drawings, wherein:

' Fig. 1 is a fragmentary detail viewypartly in section and partly in elevation, of a corner portion of a closure structure constructed in accordance with the invention.

Figs. 2, 3, 4, and 5 are, respectively, sectional views taken on the lines 2-2, 33, 4-4 and 5-5 of Fig. 1.

Fig. 6 is a perspective view of one of the outer tubes of the marginal frame structure.

Fig. 7 is a perspective sectional view of the device shown in Fig. 5.

Fig. 8 is a perspective view ployed.

Fig. 9 is a perspective view, partly in section, showing another washer employed in the marginal frame structure.

Fig. 10 is a perspective View in section and partly in elevation, showing a coupling member of the structure with transversely disposed bars engaged at their end portions with each other within the coupling in their primary relative positions prior to effecting final positioning thereof of a washer emto interlock all' of the said bars with each other against withdrawal from the coupling.

Fig. 11 is a view similar to Fig. 10 showing the bars in their ultimate assembled relation within the coupling member.

Fig. 12 is a composite view, partly in section, showing the end portions of the bars to be engaged in the coupling members in their relative positions prior to effecting assembly thereof within said coupling.

Fig. 13 is a fragmentary detail sectional view taken on the line l3-l3 of Fig. 10.

Fig. 14 is a view similar to Fig. 10 illustrating a modification of the structure of the latter.

Fig. 15 is a view similar to Fig. 12 showing the end portions of the bars of Fig. 14 in their rela tive positions preparatory to effecting assembly thereof within a coupling member.

' Fig. 16 is a sectional view takenon the line Hi -l6 of Fig. 14.

Fig. 17 is an elevation view of the corner of the frame shown in Fig. 1.

The marginal frame of the structure is composed of corner members I having tubular arms to receive telescopically the sectional tubular parts or outer sleeves 2 at the ends of the side andend rails of the marginal frame. As shown in Fig. 6 each of the outer tubes 2 is composed of sheet metal bent to form a substantially rectangular tube structure and has overlapping flanges 3 and 4- disposed preferably to constitute the overlaps the abutting ends of the two inner tubes as shown at 6 in Fig. 1.

The said inner and outer tube sections composing the side and end rails of the frame, are provided at regular intervals with openings for the passage of the outer end portions of the marginal rods 1 and 8 of the knockdown grill structure into the said side and end rails. Each of said rods 1 and 8 is provided adjacent its outer end with recesses 9- which border the inner end of the head in.

The head Ill of eachof the marginal rods 1 and 8 is received in the longitudinal slot llof the device shownin Fig. 5- which consists of a hollow casting or forging having a bottom wall [2 equipped with said slot II and which, in the instance illustrated, has side and end walls but no front wall and the top wall of which is equipped with a boss I3 through which the threaded opening I4 passes and which receives adjusting screws 15 hereinafter described. By means of said screws l5 said device hereinafter referred to as element [2 is adjusted in position between the inner and outer peripheral walls of the marginal frame. The slot II is enlarged arcuately at points I6 in axial alignment with the threaded opening M to permit the shank of the adjusting screw IE to pass through the same.

In the instance illustrated the bars of-the grill structure including the said marginal bars 1 and B, are shown as being square in cross section. The openings in the telescopically interengaged tubular sections composing the side and end rails of the frame structure are shown as being equipped with openings of appreciably larger size than the cross sectional dimensions of said rods 1 and 8. Washers I! equipped with square openings l8 are shown in Fig. 9. Each of the openings I8 is bordered by a flange H! which engages in the opening through which a rod 1 or 8 passes and serve as bushings or fillers for said openings. Each washer I1 is equipped adjacent one end thereof with a counter-sunk opening 20 in which the inner end-of the set screw l5 engages.

Each of the set screws 15 is equipped, preferably, with a polygonal head 2| and is also equipped between said head 2| and a collar formation 22, with an annular recess which is engaged in a split washer 22 Saidwasher 22 is equipped with an end flange 23 and is inserted into the marginal frame after the screws iii to be engaged thereby are in place and engaged with the member 12 to cause the inner end 24 of its longitudinal slot 25 to receive the said recessed said washer being sprung into place in an obvious manner. The flange 23 affords a means for effecting disengagement of the washer from the screw l5.

It will be obvious that by rotating the set-screw l5 clockwise the said member [2 engaged therewith will be moved toward the outer peripheral wall of the marginal frame to draw a marginal rod 1 or 6 into the latter and by rotating the screw 15 anticlockwise saidmember [2 will be moved toward the inner wall of the -marginal frame thus to project a marginal rod 1 or 8 in the opposite direction.

It will be obvious, of course, that each of the screws l5 must be threaded into the member I2 and itslowerend engaged in the opening 20' of the washer l1 before the washer 22 canbe moved into place to prevent longitudinal movement of said screw l5 relatively to the marginal frame.

The knockdown grill structure-is composed of said marginal rods 1' and 8 and additional rods 26 and 21, respectively, and coupling members 28. All rods 26 will be of equal length and all rods 2'lwil1 be of equal length; whereas-the marginal rods l and 8, respectively willbe of lengths determined by the dimensions of the marginal as extending vertically. In the instance illustrated the coupling members 26 are shown as equipped with diagonally disposed openings or passages within which the opposed end portions of rods 1 and 26, 8 and 21 are engaged, as shown in Fig. 1.

Obviously, between the terminal rods 1 at opposite sides of the frame structure there may be one or more axially aligned rods 26 and the requisite additional coupling members 28 and, similarly, with respect to the length of the frame, the number of rods 8 and 21 and coupling members 28 will vary.

As shown in Figs. -13 inclusive, each of the rods 26 is equipped at its ends with projections 29 of a width equal to the width of the body portion of the rods 26 in one direction and half the width thereof in the other direction, said projections 29 being preferably provided with arouate ends to fit similar shoulder formations at the junction of each of the projections 29 with the body of the rod. Substantially midway between the ends of each of said projections 29 the latter is'provided in the instance illustrated with opposed side recesses 30.

The vertical rods 21, including also the terminal ends of the rods 8 to be engaged in couplings 28, are shown as equipped with longitudinal projections 31 of a width at their extremities equal to the width of the recesses 30 of the projections 29 so that they may pass snugly through said recesses in inserting said rods into the coupling members 28.

The said projections 3| of the rods 27 are provided between their ends with side recesses 32 in which the portions of the projections 29 adjacent one side of each of the recesses therein are adapted to be received so that, after assembly of the structure as shown in Fig. 10 has been effected, the said rods 26 are pulled apart as shown in Fig. 11 to interlock the projections 3| of the rods 21 with the projections 29 of the rods 26 and thereupon none of the rods 26 or 21 can be withdrawn from the coupling without eifecting breakage thereof within the coupling.

While square rods are illustrated herein it will be obvious that rods of any other cross-sectional shape may be substituted therefor.

It. will also be obvious that the interlock or interengagement of the projections 29 and 3! is maintained by subjecting the rods 26 to tension stress or suitably holding them against movement toward each other whereas the rods 21 maybe subjected to either tension or compression stress selectively.

By reversing the positions of the side recesses of the projections 3! so that they are transposed oppositely from the positions shown and also disposing the side recesses of the projections 26 so that they are offset from each other when the extremities of the said projections 29 are in contact with the shoulders opposed thereto and then pulling the rods 26 apart until the side recesses thereof register with each other, the projections 3| maybe passed through said side recesses and by then restoring the rods 21 to position wherein the extremities of the projections 29 contactwith the shoulders opposed thereto, the projections 3| will be interlocked with the projections 29 and held against withdrawal from the coupling. This modification will be readily understood by persons skilled in the art without special illustration and it will also be obvious that in this modified structure the rods 26 must be held against separation, preferably, by maintaining them under sion of the couplings 28 may be such as to proaxial compressionstress,

trated in Figs, 1-4 inclusive and Fig. 6 consti- It will also be noted that by reason of the length of the projection 29 of the, rods 26 and the projections 3l of the rods 21, each of said rods 26 and 21 has a very long bearing or extension portion within the coupling, this being very desirable in order that the width and length of. the cou pling member may be reduced to a minimum size and thus exclude less light than is excluded by a larger size coupling. The cross sectional dimenvide ample strength to resist destruction thereof for the purpose of disengaging any of the rods 26 and 21 therefrom. In the instance illustrated the projections 3| of the rods 2'! are shown as being of less width than the body portions ofthe said rods, but it will be obvious that the width thereof may be coincidentwith the width of the face of the rod with which said projections are flush, without departing from the invention; though obviously, in such event, the side recesses of the projections 29 of the rods 26 will have to be lengthened accordingly,

The structure illustrated in Figs. 1013 inclusive is intended to be subjected to tension at least axially along the composite horizontal bars of the latter, Whereas the vertical bars thereof may be subjected either to tension or compression at will. Obviously, the relative arrangement of the bars 26 and 21 may be reversed so that the bars 21 extend horizontally and the bars 26 vertically,

this being desirable in the case of the closure structures of great length, for the reason that alternate axially aligned composite bars 2'! may, in that event, be placed under tension and compression respectively, to prevent bowing or distortion of the long side railsof the marginal of the screws to resist rotation of the latter to such an extent as to produce the effect of a locknut connection as will be obvious, this being decidedly desirable to prevent relief of the stress applied to the rods by the members l2 under the influence of ordinary vibration and temperature change. i

g, In the structure of Figs. 14-16 inclusive, the

overlapped end portions 33 of thehorizontally disposed rod 34 engaged in a couplingumember 28 are provided each with only one side recess 35 toreceive a projection 36 at the end of a vertical rod 31, thereby preventing relative movement of the overlapped rods 34 in any direction relatively to each other and relatively to the coupling 28. In this structure the vertical rods 31 must be maintained under a pressure stress in order to maintain said projections 36 engaged in said recesses 35 as will be obvious. The advantage of the structure of Figs. 14-16 inclusive, lies in the fact that the structure lying within the coupling member 28 will be of greater strength than would be true of the structure shown in Figs. 1-13, inclusive.

i Except as to the details of construction of the members 12 and the washers and other parts associated therewith, the. marginal frame illustutes no part. of the present invention.
