Description: .AN ADJUSTABLE SUPPORTING STRUCTURE FOR ARMORED DOORS AND AN ADJUSTABLE FRAME THEREOF. This invention relates to a support structure for an armored door which ' is adjustable both in height and width, as well as to a fixed frame thereof which is likewise adjustable in height and width. As is known, armored doors are provided with a very rugged inner metal structure that is conveniently covered as, for example, by wood panels or the like. Such metal structure are normally of fixed size and, thus, they are to be prepared according to door di - mensions that are required each time. This is obviously a great disadvantage and will also affect the final cost of an armored door since its me tal structure has to be constructed on specific demand. Attempls have been made in order to make said structures adjustable in height by performing a precutting operation on the lower part thereof but without facing the problem of their adaptability in width. Thus, a maximun height is chosen as a starting height and if a wall opening where a door is to be mounted is smaller in height, some precut -. portions are removed from the structure to fit this latter and, therefore, the door itself to the height of the wall opening. This is, in any way, not a satisfactory approach since it d.oes not permit the height to be adjusted to a large extent and it is bound to the width to be ; prefixed width. The present invention overcomes the foregoing disadvantages by providing a metal structure for armored doors which is able to be adjusted both in width and lenght to a large extent such that it can be adapted for practically any size of door wall opening. The invention also provides a frame, likewise adjustable in width and height, which is adapted for accommodating said structure or, more specifically, the armored door as obtai¬ ned from such a structure. Moreover, the structure of the invention is also a reversible structure in that it can be either a right-handed or a left- handed structure so that the hinge side of the armored door may be selected according to requirements. The metal structure for armored doors in accordance with the invention is characterized in that it includes a pair of substantially vertically extending eletiaαts one of which e- le ents is associated with a post member carrying a hinge means and the other one with a post member carrying a lock means, said elements being able to slidably move horizontally with respect to one another and including means for permitting mutual interengagement; provided at the top and bottom of said elements being pairs of slides whiφ are vertically slidable rela' to said elements, the two slides of each pair being also able to move in an horizontal direction with respect to one ano -> ther. More particularly, the two upright elements, in addition to their respective post members, also have metal plates asso¬ ciated thereto which at least partially overlap one another and which are provided with reinforcing cross-pieces. The upper and lower slides include respecitve post pieces which are designed to be at least partially accommodated in the post members of the upright elements, as wel]as respecti ve plates which overlap, by mutual interengagement, the cor- responding plates of said upright elements. Thus, the structure can be adjusted both in width and lenght to fit the required dimensions. After the structure has been adjusted to the desired dimensions, the entire assemblage is secured together by the aid of screws. Associated to said structure is a correponding frame which is likewise adjustable in width ard lenght and which inclu-» des a pair of frame posts having precut portions at the up_ per and lower ends thereof, as well as a pair of upper an¬ gle members the vertical limbs of which are received in-sa_ id frame posts while the horizontally directed limbs are fitted into one another, one of these horizontal limbs having pre_ cuts provided in it. Other features of the invention will readily appear from a reading of the following detailed description made in con- nection with one embodiment thereof shown by way of a non restrictive example by the accompanying drawings, in which: - Figure 1 is an axonometric, exploded view of an adjusta¬ ble structure for armored doors according to the invention; - Figure 2 is an axonometric, exploded view of a correspoj dingly adjustable frame of the above structure. Referring now to figure 1, reference numeral 1 in this fi¬ gure generally designates an adjustable metal structure for an armored door according to this invention. It essentially comprises two vertically extending elements 2 and 3 including post members 4 and 5 respectively, the structure post member 4 carryng hinge means 6 and the struc. ture post member 5 having al least one lock means 7 associa_ ted therewith . The elements 2 and 3 further include plates 8 and 9 respe¬ ctively, which are designed so as to be able to slide hori¬ zontally over one another to cause mutual interengagements to take place. More parcicularly, cross-pieces 10 of different lenghts are carried on plate 8 and are able to be received and to slide in an horizontal direction in corresponding grooved guides 11 carried on plate 9. During this sliding movement the plate 8 will at least in part overlap the plate 9. Moreover, the plate 8 is further strengthened by the provi¬ sion of a vertically extending rib 12 which is discontinued where the cross-pieces 10 are placed, while the plate 9 is reinforced by similar ribs or hollow vertical protrusions 13. Thus, the elements 2 and 3 can slidingly move horizontally with respect to one another from a position- where the cross- pieces 10 are entirely fitted in the corresponding grooved guides 11, to a position where only the ends of the cross- pieces 10 jutting out of plate 8 are fitted in said guides thereby to obtain an adjustment' in width of the structure. After the elements 2 and 3 have been , adjusted to a position corresponding to the desired door width, they are firmly locked together by the aid of socket head screws 14 (only one shown in figure) passed through respective registering holes 15 formed in plates 8 and 9. Dotted regions in figure 1 shown some of the holes 15 which can be made to accurate , ly register for a given position of elements 2 and 3. Provided at the top and the bottom of elements 2 and 3 are pairs of slide means 16 an 17 respectively. Each slide 16, 17 includes a post-piece 18, 19 which is de¬ signed to be received, in a vertically movable manner, in post members 4 and 5 of elements 2 and 3 respectively. The slides 16 and 17 further include plates 20 and 21 re¬ spectively designed so as to be vertically slidable relati¬ ve to the corresponding uppermost and lowermost ends of pla_ tes 8 and 9 to partially overlap these latter, as clearly shown in figure 1. In order to permit occurrence of this vertical sliding movement,, the plates 20 and 21 have slits 22 formed therein to provide for mutual telescoping of ele¬ ments 16,2 and 17,3 respectively. Moreover, each slide element is provided externally, along a vertical edge 23 thereof, with precut pieces 24, some of which may be removed according to the required amount of penetration of said slides into elements 2 and 3, in such a manner that said edges 23 will constitute the extension of corresponding edges 23' provided on post members 4 and 5 to serve as weather or sealing strip supports. Arranged in mutual alignment on the external side of each slide elements 16 and 17 are U-shaped guides 25 and 26 which are secured to plates 20 and 21 respectively. Obviously, the slides 16, 17 are also able to move in an horizontal direction relative to one another, with the associated plates 20 and 21 being in a partially overlap¬ ping relationship to one another. The slides 16, 17 are also fastened to the elements 2, 3, in order to complete the structure, by means of socket hand screws 14 passed through corresponding holes 15 which are in registered relationship with each other after assembling has been carried out. Arranged in said U-shaped guides 25 and 26 is a corrispon- ding profile 27 provided with an outwardly directed longitu. dinal opening 28 which is designed to accommQdate a seal strip channel 29 or a draught-guard strip 30 according to whether said profile is at the top or the bottom of the structure 1. The just described metal structure 1 is one which is rever- sible in that it may be turned over with respect to its p_ sition in figure 1 by reversing the positions of the upright elements 2 and 3 according to whether a right-hand or a left-hand-opening arrangement is desired The adjustable frame associated with the structure 1 is shown in figure 2 where it is designated generally by refe¬ rence numeral 31. It comprises two frame posts 32 and 33 which have precut re. gions at their top and bottom ends such that post-portions may be removed therefrom for adjustment in height. Arranged at the top of frame posts 32 and 33 are L-shaped angle members 35 and 36 of which the vertically extending limbs 37, 38 are received in frame posts 32, 33 respective- ly, and the horizontally extending limbs 39, 40 are fitted into one another. Adjustment in width is likewise obtained by removing precut portions 41 from the end of the horizontal limb 40 of member 36 in which the limb 39 of member 35 is received. In this case too, the various elements are secured together by the aid of socket head screws 14 (only one shown in figu. re 2) passed through corresponding registered holes 15 for¬ med in the two elements to be fastened to one another. The frame post 32 also has hinge means 42 provied thereon which are complementary to hinge means 6 on structure 1. The hinge means 42, that are arranged in pairs, are secured to frame post 32 by the aid of a spring pin 43 and a sαεw 44 (see detail .figure 2) . Of course, firstly the lower hinge means 42 of each pair will be put in place and then, after the complementary hinge mea s 6 on structure 1 have been engaged therewith, the upper hinge means 42 will be secured to the frame post 32. It should be apparent that the structure for armored doors and its associated frame according to the invention, are not bound to the specific embodiment described in the fore¬ going and shown in the accompanying drawings and a number of detail modifications may be made thereto as will be readily conceived by those skilled in the art, all of such modifica. tion being intended to fall within the scope of this invention,
