Description

CONTRAMARCO FOR SLIDING BLADE.

Description:

The present invention relates to a counter frame for sliding sheets, and more exactly for recessed sliding sheets.

The main technical field of application of the present invention is that of the door and window production sector.

Generally, the counter frames are constituted by a porticoed portion, which defines the passage opening of the door or window, and a seating portion, embedded in the masonry and defining a housing for the leaf.

Said seating portion may be of the "open" type, that is to say defined by a crosshair of sleepers and sleepers, or of the "closed" type, or defined by a box-like body, or ark, typically metallic.

The present invention will refer especially to the counter frames that have a "closed" type portion of the enclosure.

In the known technique, counter frames of that type comprise a substantially parallel parallelepiped metal box having a lateral opening for introducing or removing the sheet.

It should be noted that the dimensions of these metal boxes are defined based on the size of the sheet.

In other words, for each sheet you have to make a corresponding counterframe of predetermined dimensions.

Unfortunately, the above imposes an important conditioning to the flexibility of the manufacturer, which must face, as an alternative, numerous machine stops, due to the configuration time necessary to modify the manufacturing parameters, or the duplication of the machinery.

In this context, the technical task that constitutes the foundation of the present invention is to propose a counterframe for sliding blades that eliminates the drawbacks of the known technique cited above.

In particular, the present invention aims to make available a counter frame for sliding blades in a position to increase the manufacturer's productive flexibility.

Another objective of the present invention is to propose a counter frame for versatile sliding blades and whose installation is simple.

The established technical task and the specified objectives are substantially achieved by means of a sliding frame counterframe, which comprises the technical characteristics set forth in one or more of the appended claims.

Other advantages and features of the present invention will be better apparent from the indicative and, therefore, non-limiting description, of a preferred but not exclusive embodiment of a counter frame for sliding sheets, as shown in the drawings annexes, in which: Figure 1 is a perspective view of a counter frame for sliding sheets according to the present invention; Figure 2 is a perspective view of a detail of the counter frame of Figure 1 with some parts omitted to highlight others; - Figures 3 and 4 are front sectional views of the counterframe of Figure 1 in two different operating configurations, the section having been made in correspondence of the housing of a sliding sheet; Figures 5 and 6 are front sectional views of a detail of the counterframe of Figure 1 in two different operating configurations, the section having been made outside the housing of a sliding sheet.

With reference to the attached figures, a counterframe for sliding sheets according to the present invention is indicated with the number 1.

The counterframe (1) comprises a box-like body (2) and a portal (3) juxtaposed with each other and substantially aligned along a direction of travel "A" of a sheet (not shown).

The box type body (2) defines a housing (2a) for housing said sheet.

In particular, the sheet, moving along the direction of travel "A", enters or exits the opening (2a), through an appropriate opening (2b) transverse to the direction of travel "A", to open or close, respectively, a gap (3a) defined by the portal (3).

Such opening (2b) extends through a plane "D" transverse to the direction of travel "A" along its own preponderant extension direction "B".

The opening (2b), in addition, extends through a secondary direction "C" of extension, transverse to the preponderant extension direction "B".

Preferably, the box-like body (2) has two bases (5 and 6), opposed to each other, and a plurality of side walls (7).

More precisely, the box-like body (2) has a first (5) and a second base (6) facing each other and connected by the side walls (7).

In the preferred embodiment, the box-like body (2) has a substantially parallelepiped conformation.

In other words, the two bases (5 and 6) have a substantially quadrilateral conformation and are connected to each other by three side walls (7), each corresponding to a respective side of the base.

More precisely, a first (7a) and a second side wall (7b) are arranged facing each other and substantially parallel, and a third side wall, or side, (7c) connects said first (7a) and second side wall ( 7b) and is substantially orthogonal to them.

It should be noted that the third side wall, or side, (7c) is arranged substantially opposite the opening (2b) and defines a closing partition of the box-like body (2).

For reasons of ease of description, the distance between the first (5) and the second base (6) will then be defined as "height" of the body type box (2).

In addition, the distance between the first (7a) and the second (7b) side wall will then be defined as "depth" of the box-like body (2).

The distance between the opening (2b) and the third side wall (7c), on the other hand, will be defined as "width" of the box-like body (2).

It should be noted that the height and depth of the box-like body (2) substantially correspond to the dimensions of the opening (2b) measured along the extension directions "B" and "C" respectively.

Preferably, the height of the box type body (2) is adjustable.

More preferably, the first (5) and the second base (6) can move in reciprocal approach and / or distance along the preponderant extension direction "B" of the opening (2b) between a minimum distance position, or proximal, and a position of maximum distance, or distal.

In other words, the bases (5 and 6) move along their own joining line, preferably orthogonal to them, to vary the height of the box-like body (2).

Advantageously, this allows the height of the box-type body (2) to be adapted to the dimensions of the sheet directly during the installation of the counterframe (1).

Preferably, the box-like body (2), at least in part, is defined by an upper portion (8), which comprises the first base (5), and a lower portion (9), which comprises the second base (6) .

Such upper portion (8) and lower portion (9) may reciprocate with each other along the preponderant extension direction "B" of the opening (2b) to move the bases (5 and 6) between said distal positions (of maximum distance) and proximal (minimum distance) depending on the dimensions of the sheet.

More precisely, the upper (8) and lower (9) portions are connected with reciprocal freedom of movement and preferably define a substantially telescopic structure.

In the embodiment shown, the upper (8) and lower portions

(9) present, both, transversely to the direction of travel "A",

a cross section profiled substantially in "U". In other words, the upper portion (8) has two limb elements that extend transversely to an intermediate element, which defines the first base (5).

Similarly, the lower portion (9) has two limb elements that extend transversely to an intermediate element, which defines the second base (6).

Such upper (8) and lower (9) portions are arranged opposite each other and the concavities of the cross sections are facing each other.

In other words, the upper (8) and lower (9) portions are partially copenetrating each other.

In other words, the upper portion (8) and the lower portion (9) are connected with freedom of movement in correspondence of their respective limb portions.

Preferably, in addition, both the upper portion (8) and the lower portion (9) each comprise a bulkhead (8a, 9a), transverse to the "U" section, which partly defines the side (7c) of the body type box (2).

The counterframe (1), furthermore, comprises means for blocking (10) the relative displacement between the upper portion (8) and the lower portion (9).

Advantageously, this allows the distance between the first (5) and the second base (6) to be set after the regulation.

In the embodiment shown, the upper portion (8) comprises at least one through groove (11) extending parallel to the preponderant extension direction "B" of the opening (2b) and facing a respective hole (12 ) intern made in the lower portion (9).

More precisely, the upper portion (8) has at least one groove (11) for each limb element.

Similarly, the lower portion (9) has at least one through hole (12) for each end element.

The blocking means (10) comprise at least one clamping element (not shown) through the groove (11) and the respective hole

(12)

to link the upper portion (8) to the lower portion (9). Preferably, the clamping element is defined by a rivet.

(not displayed). Alternatively, the clamping element can be defined by a bolt

or similar elements.

In an alternative embodiment, not exhibited but functionally analogous, the lower portion has the grooves, while the upper portion has the through holes.

Preferably, also the depth of the box-like body (2) is adjustable.

In particular, the first (7a) and the second side wall (7b) of the box-like body can move with each other in respective approach and / or distance between a proximal position, or minimum distance, and a distal position, or maximum distance . Such possibility of reciprocating and / or reciprocating movement is given transversely to the preponderant extension direction "B" of the opening (2b).

In other words, the first (7a) and the second side wall (7b) can be moved along a joint line of the same walls, that is, parallel to the secondary extension direction "C" of the opening (2b ).

Advantageously, the above provides the possibility of adapting the depth of the box-like body (2) according to the thickness of the sheet.

For this purpose, the upper position (8) and / or the lower portion (9) each comprise a first (14a, 15a) and a second subpart (14b, 15b) facing each other and each defining in part the first (7a) and the second side wall (7b).

More precisely, the subparts (14a, 15a, 14b, 15b) are bodies that have a substantially profiled cross-section in "L", that is, each having a respective base sheet (20), which partly defines a of the bases (5, 6), and a respective lateral sheet (21), transverse to the base sheet (20) and which partly defines the premiums (7a) or the second lateral wall (7b).

Each first subpart (14a, 15a) faces the respective second subpart (14b, 15b) so as to define the "U" profiling of the upper (8) or lower (9) portion.

In other words, the base plates (20) of the first (14a, 15a) and the second subpart (14b, 15b) are headed together, while the side plates (21) face each other.

Preferably, each first subpart (14a, 15a) is mobile in approach and / or away from the respective second subpart (14b, 15b) to define the positions of maximum (or distal) distance and minimum (or proximal) distance between the first (7a) and the second side wall (7b).

Also, in the embodiment shown, each first subpart (14a, 15a) has its own transverse partition (18a, 19a) that extends transversely to the direction of travel "A" in approach to the respective second subpart (14b, 15b ) to define in part the said screen (8a, 9a) of the respective portion (8, 9).

Similarly, each second subpart (14b, 15b) has its own transverse septum (18b, 19b) that extends transverse to the direction of travel "A" in approach to the respective first subpart (14a, 15a) to be defined in the remaining part said screen (8a, 9a) of the respective portion (8, 9).

Preferably, the partition (18a, 19a) of each first subpart (14a, 15a) is superimposed, at least in part, on the partition (18b, 19b) of the respective second subpart (14b, 15b) or vice versa.

Thus, during the relative displacement between the first (7a) and the second side wall (7b), the partitions (18a, 19a) of the first subparts (14a, 15a) move over the partitions (18b, 19b) of the second subparts (14b, 15b) defining the respective bulkhead (8a, 9a) substantially completely.

Similarly, the base sheets (20) of the first (15a) and the second subpart (15b) of the lower portion (9) are superimposed, in part, on each other in order to substantially define the second base substantially ( 6) even during removal of the first (7a) with respect to the second side wall (7b).

The upper portion (8) of the box-like body (2) comprises at least one separating element (22) interposed between the base sheets (20) of the first (14a) and the second subpart (14b).

In the embodiment shown, the separator element (22) extends along the entire width of the box-like body (2) in part defining the first base (5).

Preferably, the separator element (22) protrudes into the opening (2a) of the box-like body (2) defining a fixation for a leaf guide rail.

Preferably, in addition, a cover plate (23) is rigidly connected to the separator element (22) which extends parallel to the base sheets (20) of the first (14a) and the second subpart (14b) and in superimposed part to them.

In other words, the separator element (22) and the cover plate

(2. 3)

they define a body that has a substantially profiled cross section in "T", where the leg of the "T" corresponds to the separator element and the head of the "T" corresponds to the cover plate (23).

Thus, the base sheets (20), together with the cover plate

(2. 3)

they define the first base (5) of the box-like body (2) substantially completely. The counterframe (1), furthermore, comprises means for regulating (16) the distance between the first (7a) and the second side wall (7b).

Preferably, the regulating means (16) comprise at least one active cam member (17) between the first (7a) and the second side wall (7b).

In particular, the cam member (17) is disposed between each first (14a, 15a) and second subpart (14b, 15b).

More particularly, the regulating means (16) comprise a plurality of cam members (17) arranged between each first (14a, 15a) and second subpart (14b, 15b).

Advantageously, this allows an installer to adjust the distance between the first (7a) and the second side wall (7b) of the box-like body (2) simply by rotating each cam member (17) around its own center of rotation (17a ).

Likewise, such cam member (17) is substantially defined by a discoidal element (24) having a center of rotation (17a) and having two substantially curved, preferably semicircular, through grooves (25) facing each other.

Such grooves (25) are preferably eccentric with respect to said center of rotation (17a).

In particular, such grooves (25) extend along a substantially semicircular path between a first end (25a), proximal to the center of rotation (17a), and a second end (25b), distal to the center of rotation (17a ).

The first ends (25a) of the grooves (25) are arranged equidistant from the center of rotation (17a) and are aligned along a joint line that passes through that center of rotation (17a).

Similarly, the second ends (25b) of the grooves (25) are arranged equidistant from the center of rotation (17a) and are aligned along a joint line that passes through such a center of rotation (17a).

Likewise, each groove (25) is crossed by a respective plug (27), each integral to the first (14a, 15a) or the second subpart (14b, 15b), respectively.

During use, by rotating the discoidal element (24), the shafts (27) move specularly between the first (25a) and the second end (25b) of the groove (25).

When the plugs (27) are in correspondence of the first ends (25a), the subparts (14a (or 15a), 14b (or, respectively, 15b)), and therefore the first (7a) and the second side wall (7b) are in the proximal (or minimum distance) position.

On the contrary, when the plugs (27) are in correspondence of the second ends (25b), the subparts (14a) (or 15a), (14b) (or, respectively, 15b)), and therefore the first ( 7a) and the second side wall (7b) are in the distal (or maximum distance) position.

By means of corresponding stop means, the plugs (27) are locked in the desired position to fix the distance between the walls.

Preferably, also, at least one of the cam members (17) is connected with freedom of rotation to the separator element (22) and is active on the first (14a) and the second subpart (14b) of the upper portion (8) . In this case, advantageously, it is bolted to the separator element (22) at its own hinge point, which corresponds to the center of rotation (17a).

It should be noted that, since the movement of the subparts (14a, 14b) is substantially symmetrical with respect to the separator element (22), given the structure of the cam element (17), the guide rail (28) of the blade is always centered in the opening (2a) of the box type body (2) independent of the desired dimensions.

Preferably, the regulating means (16) comprise at least two cam members (17) disposed between the base sheets (20) of the subparts (14a, 14b) of the upper portion (8).

Also, the regulating means (16) comprise at least two cam members (17) disposed between the base plates (20) of the subparts (15a, 15b) of the lower portion (9).

Preferably, the regulating means (16) further comprise at least two cam members (17) disposed between the transverse partitions (19a, 19b) of the lower portion (9).

When the cam element (17) is located between each first (14a, 15a) and second subpart (14b, 15b) not in correspondence of the separator element (22), in such first (14a, 15a) and / or second subpart ( 14b, 15b) there is, in correspondence of the center of rotation (17a), a groove (which can be observed for example in Figures 3 and 4) which extends along the secondary direction "C" of extension and in the which is introduced the possible rotation bolt of the cam element (17), to allow reciprocal adjustment between the first (14a, 15a) and the second subpart (14b, 15b) in the regulation of the position by work of the same element of cam (17).

In the preferred embodiment, the positions that can be assumed by the side walls (7a, 7b) are preferably two, the distal and the proximal, in accordance with current regulations on doors and recessed windows.

For this purpose, each cam member (17) has two holes (26) facing each other, preferably arranged at approximately 180 ° with respect to each other, to which the same number of through holes in the bases (5, 6) correspond. ) or on the plate (23).

The holes (26) of the cam members (17) are rigidly coupled with the respective holes of the box type body (2) to fix the dimensions of the same box type body (2).

In embodiments not shown, it is possible to include more holes in the cam members so as to be able to obtain a greater amount of dimensions of the opening (2a).

In general it is possible to exploit the action of the cam organs (17) to obtain a continuous regulation of the depth of the box-like body (2). In order to securely set the desired position as a result of the regulation, appropriate locking means can be provided (or performed at the moment). The moving parts with respect to each other can be fixed to each other, once the desired regulation is obtained, in various ways (for example by riveting, abalone, by means of fixing screws or the like).

The portal (3) comprises a sleeper (3b) to be connected to the box type body (2). The portal (3) comprises a post (3c) orthogonal to the crossbar (3b) and also the latter to be connected to the body type box (2), for example through the crossbar (3b). In the case of counter frames for sliding doors with several leaves, for example with two leaves, the upright (3c) can be replaced by another box-like body, for example, for another sliding sheet. The other box type body may have the characteristics and peculiarities of the box type body (2) described above. The other box type body in general will be placed in a mirror position to the box type body (2) with respect to a medium vertical axis of the portal (3). In the case shown in the figures, the upright (3c) is a simple upright that serves (directly or with the interleaving of another element or structure) as a closing stop of the sliding sheet.

Preferably, the guide rail (28) of the sheet extends from the inner part of the opening (2a), along the first base (5) and along the crossbar (3b).

In the embodiment shown, the guide rail (28) comprises two rails parallel to each other and connectively connected to the separator element (22), for example through the plate (23).

Preferably, the width of the crossbar (3b) transversely to the preponderant extension direction "B" of the opening (2b) is adjustable, to adapt the crossbar (3b) to a variation in the depth of the box-like body (2). Such regulation possibility occurs parallel to the secondary direction "C" of extension of the opening (2b). With reference, in particular, to Figures 5 and 6, in the specific case the crossbar (3b) comprises two lateral parts (30 and 30 ') movable along the secondary direction "C" of extension of the opening (2b ) in reciprocal approach and / or distance between a proximal or minimum reciprocal distance position (shown in Figure 5) and a distal or maximum reciprocal distance position (shown in Figure 6). The counter frame (1) comprises locking means (31) of the reciprocal position of the two lateral parts (30 and 30 ’) of the crossbar (3b). Preferably, the two lateral parts (30 and 30 ’) can move relative to a central part (32) of the cross member (3b). The rail (28) is associated to the central part (32). In the embodiment shown in Figures 5 and 6, the locking means (31) of the reciprocal position of the two lateral parts (30 and 30 ') of the crossbar (3b) comprise means (33) of reciprocal interference between each of the lateral parts (30, 30 ') and the respective portion of the central part (32). In particular, the reciprocal interference means (33) comprise holes (34), in which it is possible to link elements (35) elastically retractable and / or detachable by means of the action (compression and / or traction) with a tool suitable for such effect. In the specific case of the embodiment shown, the holes (34) are associated with the central part (32) and the elements (35) are associated with the lateral parts (30 and 30 ’). However, the placement could be inverted or alternated, being only careful to place an element (35) in the

another part with respect to that in which the respective hole (34) is located. The present invention achieves the objectives defined in advance and achieves important advantages. In fact, the mobility of the two bases in approach and / or 5 reciprocal distance allows varying the height of the body type box adapting it to the various dimensions of the sheet. On the other hand, the telescopic configuration of the structure provides simplicity and speed of regulation. In addition, the possibility of regulating the structure also in

10 depth further increases the flexibility of use of the counterframe, increasing the manufacturer's productive flexibility, which with the production of a single counterframe typology can satisfy requests for sheets with different sizes.

On the other hand, the presence of cam organs makes regulation 15 precise and extremely diligent.
