Description

The present invention relates to a door and window wood frame provided with improved assembly and actuating means.
More paricularly it is a subject matter of the present invention a wood frame in which the above means allow to simplify and make faster the manufacture thereof with respect to the presently used processes.
According to the present prior art, it is necessary to define two different manufacturing methods, that is a first method characterized by a craftsman work requiring a highly skilled operator who however will not be able to exceed some production and quantity standards, and a second method characterized by industrial scale working which, necessarily, must be provided with expensive and complicated operating machines in order to obtain required production and quantity standards.
Anyway, the working steps for manufacturing door and window wood frames can be summarized as follows:

shaping of bars obtained from normalized or standard wood boards;
tenoner working of every members to be subsequentely joined;
machine working of the frame posts and wings for hinge centering and mounting;
molding machine working of a wing-post for mounting a closure set;
reciprocal gluing of the wing members by means of suitable benchs assuring a perfect perpendicularity of the contained glass pane.

It is to be pointed out that the above mentioned operating machines are complicated cumbersome and very expensive, so that they are used only for industrial scale productions, while for craftsman productions are used hand means and process which, clearly, cannot obtain acceptable quantity and quality results.
A further drawback connected to wood frames of traditional kind consists of the fact that their wing,or frame substantially formed by post and cross member assembly, is a completly integral framing, as said members are each other glued.
Another drawback connected with traditional frames consits of the fact that their assembly means for applying the actuating means of the frame, as for example closing devices, hinges and actuating means for said closing devices are hardly disassemblabe because they are assembled in a very complicated manner.
It is one of the main objects of the present invention to provide a door and window wood frame with improved assembly and actuating means in which its framing can be easily and completely disassembled in a short time for any maintenance operation as for example the replacement of either an actuating device or the glass pane thereof.
It is another object of the present invention to reduce the operating times for the frame manufacture, to facilitate the glas pane assembly and to set the perpendicularity thereof when they are already assembled.
It is another specific object of the present invention to succed in obtaining a production of door and window wood frames according to accettable quality and quantity standard without using the above mentioned operating machines, making easier and speeding up the manufacture thereof.
The above mentioned object is provided by means of the use of wood bars, already shaped according to the functions to be done, which need only a cutting operation according to the size of the single members forming the frame.
Said members, that is posts and cross members, will be subsequentely properly pierced at the ends thereof in order to be joined by means of disassemblabe mechanical joints, thus eliminating tenoning and gluing operations.
According to a further advantageous feature of the invention, on the posts of the frame and the wing a specific selfpositioning hinge will be able to be assembled fastened by means of usual screws eliminating the use of the proper special machine.
According to another advantageous feature of the invention, on a post of the wing a specific closing set of the frame will be able to be assembled whose assembly does not require any particular working, so eliminating the use of the molding machine..
Another specific feature of the invention consists of the fact that the wing is arranged for receiving a suitable device allowing to perpendicularly arrange a glass pane in the already assembled wing eliminating the use of benchs for assembling wings.
The features as well as the advantages of the wood frame according to the present invention will result selfevident from the following detailed disclosure of a not limiting embodiment thereof, with reference to the enclosed figures, in which:

figure 1 is a schematic frontal view of the frame according to the invention;
figure 2 is a croos-section of the frame along the line X-X of figure 1;
figure 3 is a cross-section of the frame according to the line Y-Y of figure 1;
figure 4 is an exploded view in enlarged scale of the detail indicated by the circle A in figure 1;
figure 5 is an exploded view in enlarged scale of the detail indicated by the circle B in figure 1;
figure 6 is an exploded view in enlarged scale of the detail indicated by the circle C in figure 1;
figure 7 is an exploded view in enlarged scale of the detail indicated by the circle D in figure 1, and
figure 8 is an exploded view in enlarged scale of the detail indicated by the circle E in figure 1.

Particularly referring to figures 2 and 3, there is described the shaping of bars obtained from wood beams, used for embodying the frame according to the invention which, just owing to the above mentioned shaping, are suitable to allow the necessary works for fastening the assembly and actuating means of the door and window frame.
The first bar, generally indicated by the reference 9, has a frame function showing, further to the internal shoulder 11 and the external one 12, an intermediate shoulder 10 by means of which is applied to a wing indicated by the reference 13. The shape of the cross-section of the wing 13 has the specific feature to be employed along the whole perimeter of the frame owing to the position of grooves therein provided.
Specifically, it is provided with a first groove 14 having the purpose of glass substaining channel, and a second groove 15 with sliding function for a closing device about which will be herebelow told. Said grooves 14 and 15 are perfectly aligned with the shape of the wing 13.
In figure 3 is depicted the second bar , generally indicated by the numeral 9', having the function of a lower frame cooperating too with the wing 13. The shape of these components is exactly analogous to that of the components of the figure 2 so that like members are indicated by like references. As regards the lower frame 9', both the intermediate shoulder 10' and the external one 12' can be replaced by a suitable metal bar 16.
After having described with reference to the above mentioned figures, the shape of the bars suitable to be properly worked for applying assembly and operating means, will be now discussed in detail, referring to subsequent figures, the improved assembly and operating means with which is provided the door and window frame according to the invention and the application methods thereof.
Specifically referring to figure 4, are presently described the assembly means of the adjacent ends of a post 13' and a cross member 13''.
These two ends are each other connected as depicted in the detail indicated by the circle A in figure 1.
From the above mentioned figure 4 it can be seen that both the ends of the post 13' and the cross member 13'' are pierced by substantially longitudinal bores 17' both crossed by a suitably shaped transversal bore 17''.
The above mentioned bores cross each other defining a recess 17.
The above mentioned bores have been pierced for housing a mechanical connecting joint indicated as a whole by the numeral 18, the advantageous features consists in that it may be inserted in the above mentioned bores and being composable and lockable for firmly connect the above mentioned ends of the post 13' and the cross member 13''.
The joint 18 comprises a first member 19 of substantially cylindric shape the lower portion 23 of which is a solid rod and is provided with a traversing bore 25 suitable to allow the entry of a locking screw 22 of a proper length. The portion 23 of the first member 19 provides on the opposite side, with respect to that the traversing bore 25 is visible, a recess or undercut 24 shown by dashed lines and having a length subtantially equal to the diameter of the portion 23. Such a recess 24 is open to the outside of the member 19.
The upper portion of the first member 19 has a substantial lattice structure 26 consisting of a plurality of essentially radial recesses arranged, in the present illustrative embodiment, on three superimposed planes.
The first member 19 of the joint 18 is suitable to be inserted into the longitudinal bore 17' of the end of the post 13' and, specifically, the height thereof is substantially equal to the length of said bore 17' while the location of the bore 25 is such that is going to be arranged in register with the transversal bore 17''.
The joint 18 comprises also a second member 20 essentially consisting of a parallelepiped hallow body 27 provided on two opposed sides with two properly shaped protrusions 27' and 27'', respectively. More specifically, said protrusions 27' and 27'' are two portions of an integral body 29 longitudinally traversing the body 27. The last one is further provided, on its lower side, with a shaped groove 28.
The above mentioned body 29 has a longitudinal bore 30 along the whole length till a traversing recess 31 of the portion 27' suited to receive a third member of the herebelow disclosed joint.
The second member 20 of the joint 18 is suitable to be applied to the end of the cross member 13'' and, more specifically, the substantially cylindric portion 27' thereof is suitable to be introduced into the longitudinal bore 17' of said end. The length thereof is such that, when it is inserted in the bore 17', the recess thereof 31 is aligned with the bore 17'' and, more particularly, with the recess 17.
The above mentioned third member of the joint, indicated as a whole by the numeral 21, consists of two essentially cylindric portions 32 and 32' of different diameter which are each other connected by an intermediate parallelepiped portion 33 in which is made a transversal threaded through hole 34.
The fastening of the above mentioned ends of the post 13' and the cross member 13'' is provided by inserting the first member 19 in the longitudinal bore 17' of the post 13' and, subsequentely, the hollow body 27 of the second member 20 into the recess 14 of the post 13', by inserting the portion 27'' in the transversal bore 17'' till it comes into the recess or undercut 24 of the first member 19. The second portion 27' of the second member 20 is inserted into the longitudinal bore 17' of the end of the cross member 13'' till the recess 31 is arranged into the transversal bore 17'' and at last the third member 21 is inserted in said recess 31 through said hole 17'' in order to have its parallelepiped portion 33 housed in the recess 31. At last, the locking screw 22 is provided for fastening all the above mentioned members which loock and firmly connects the two above mentioned ends. Particularly, the screw 22 is inserted into the bore 25 of the first member 19, in the bore 30 of the second member 20 for screw engaging the bore 34 of the third member 21.
Referring now specifically to figure 5, the assembling means of the end of an intermediate cross member 35 with the post 13' of the wing are described, that is the detail indicated by the circle B in figure 1. Also in this case said means consist of a disassemblabe mechanical joint, indicated as a whole by the reference 36, formed by suitable portions to be respectively fastened to the cross member 35 and to the post 13' and provided with means for locking both each other said portions and said post and cross member.
In the cross member 35 two substantially perpendicular holes are pierced, likely to what described for the figure 4, so that said holes are indicated by the same numerals.
On the contrary, in the post 13' is pierced only a transversal bore 19' of suitable length.
The joint 36 has many analogies with respect to the preceding joint 18 for both the structure and the using way.
It may be seen that said joint 36 comprises a first member 37 of essentially parallelepiped shape which is provided, on a side, with a substantially cylindric protrusion 40, thereto perpendicular and provided with a longitudinal hole 41 connected with an internal recess or undercut 42 of the body 37 open to the outside thereof. The protrusion 40 is suitable to be inserted in the hole 19' of the post 13' while the substantially parallelepiped body 37 is inserted in the groove 14 of the post 13' in which it is locked by screws 39.
Further, the joint 36 comprises a second member indicated as a whole by the numeral 38, the shape of which is very similar to that of the body 29 of the second member 20 of the joint 18.
In fact, it may be seen that the second member 38 is of substantially cylindric shape centrally structured as a lattice with essentially radial recesses arranged on superimposed planes, while at an end thereof it is of essentially parallelepiped shape and, at the opposed end, it is of cylindric shape provided with a recess 44 suitable to receive a third member of the joint 36 which will be herebelow described
The third member of the joint 36 is quite similar to the third member of the joint 18, so that it is not presently described while its portions corresponding to those of the third member of the joint 18 are indicated by the same numeral references.
The connection and locking of the intermediate cross member 35 to the post 13' by means of the joint 36 are carried out in the following way. Firstly the portion 40 of the first member 37 is inserted into the hole 19' of the post 13' and the parallelepiped portion of the body 37 is fastened in the slot 14 of the post 13'. Subsequently the second member 38 is inserted in the hole 17' of the cross member 35 till the recess 44 is aligned with the hole 17''. When the second member 38 is inserted into the hole 17', the parallelepiped end portion thereof protrudes from the end of the cross member 35 and enters into the recess or undercut 42 of the body 37. Now the third member 21 is inserted into the recess 44 through the hole 17'' so that said recess houses the parallelepipedal portion 33 of said member 21. At this time, from the backside of the post 13' is inserted a locking screw 22 crossing the hole 41 of the portion 40 of the body 37, the hole 43 of the second member 38 to screw into the threaded hole 34 of the third member 21, providing in such a way the reciprocal locking of all the members of the joint and the frame.
Referring now particularly to figure 6, is disclosed one of the assembling means of the wing 13 of the frame to the bar 9, that is a hinge, indicated as a whole by the reference numeral 45, allowing the rotation of the wing 13 with respect to the bar 9 for opening and closing the frame. This assembling means is indicated by the circle C in the figure 1.
The hinge 45 is comprised of a first member 46 formed by a plate 47 shaped in substantially complementar manner with respect to the edge of the wing 13 in such a way that its location with respect to the wing is automatic, making easy the related fastening by means of screws 48 going through holes 49 of the plate 47. The hinge 45 comprises also a second member 52 substantially fork shaped suitable to be fastened to the post 9 by means of screws 53 going through holes 54 of the member 52. Subsequently, the last one is attached to a sleeve portion of the first member 46 and subsequentely, by means of sleeves 51, a pin 50 is inserted, through holes 55 of the fork member 52, into the passage 56 of the sleeve portion of the first member 46, providing the assembly of the hinge 45. Preferably, the fastening of the second member 52 to the bar 9 is provided after the provision of the pin 50 in order to have said member as properly located as the first member 46.
Referring now specifically to figure 7, actuating means of the frame according to the invention are disclosed, particularly the closing assembly thereof comprised of the detail enclosed in the circle D in figure 1. Said closing assembly is housed in the slot 15 of the wing 13.
It is formed of blocks 55, provided with slots 56, suitable to receive slides 57 of a handle 58 inserted into square shaped rods 59 having an open side. The insertion is made integral by locking plates 60, provided with threaded holes in which are engaged screws 61. On the ends of the rods 59, through the same fastening method, are inserted push-rods 62, while along the length of the rods 59 can be inserted some blocks 63 always through the same fastening method. The obtained assembly is inserted into the slot 15 of the wing 13 by means of bridges 64 arranged at a proper space. By actuating the handle 58, it will result either a remaining or an approach movement of the slides 57 and thus of the assembly inserted in the wing 13, so providing the engagement of the push-rods 62 and the blocks 63 with the shaped plates 65 fastened to the bar 9 so obtaining the frame closure.
Figure 8 shows the detail indicated by the circle E in figure 1, consisting of a device 66 allowing to control the perpendicularity of the glass pane 72 with respect to the already assembled wind 13. Said device 66 is an angle section having at an end a thickened portion 67 and at the other end a threaded hole 68 in which is screwed a screw 69 provided with an enlarged head 70 substantially planar and suitable to abut on and engage the edge of the glass 72. The device 66 is inserted into the slot 14 of the wing 13 on which has been pierced a transversal hole 71 of which the end faced to the side of the slot 14 is suited to house the protrusion housing the hole 68. By assembling the wing 13 with the glass 72 already inserted, it is possible, at the end of the operation, to control the perpendicularity thereof resting on the thickened portion 67 of the device 66, operating through the hole 71, on the screw 69.
From what above disclosed they result apparent advantages coming from the use of door and window frame according to the present invention, the main of them having been shortly recalled at the beginning of the present disclosure.
It is clear that structurally and conceptually equivalent variations and/or changements can be provided to the frame according to the present invention, without departing from the scope thereof.
