Description
- The present patent application for industrial invention relates to the technical sector concerning the fabrication of frames by interconnecting prefabricated sections, in particular to manufacture windows and doors.
- In the manufacturing technology of frames for windows and doors, frames are manufactured by connecting several section elements in angular position. Nevertheless, in the angular junction areas it is difficult to respect the continuity and coplanarity of the external surfaces of the sections.

BE 1018055 - Said sliding wedges are associated with the main body by means of coupling means of mortise and tenon joint type, adapted to let said wedges slide with respect to the main body.
- Also patent
BE 1018055 - Only after such assembly operation, the apparatus can be positioned in correspondence of the angle formed by the profiled elements used to manufacture the window frame.
- The purpose of the present invention is to eliminate the drawbacks of the prior art, by devising a tightening and aligning device that is practical, versatile and simple to install and use.
- Another purpose of the present invention is to devise such a tightening and aligning device that is effective, efficacious and reliable.
- A further purpose of the present invention is to devise such a tightening and aligning device with reduced thickness.
- These purposes have been achieved according to the invention, with characteristics claimed in
independent claim 1. - Advantageous embodiments appear from the dependent claims.
- The tightening and aligning device according to the invention comprises a main body composed of two plate portions disposed at right angle, and two trolleys removably connected to said main body by means of bridges of breakable material.
- Each plate portion of the main body comprises an external border adapted to rest against a first longitudinal rib of a section and an internal border facing towards a second rib of the section.
- Each trolley is composed of a plate provided with an internal border facing towards the internal border of the body in order to slide on it, and an external border facing towards said second rib of the section.
- The internal border of the body is tilted by an angle with respect to the external boarder and the internal border of the trolley is tilted by the same angle with respect to the external border of the trolley. So, during the sliding of the trolley, the external border of the trolley moves away from the external border of the body, remaining parallel to the external border of the body and exerting pressure on the second rib of the section, in such manner to restore coplanarity of the two joined sections.
- The advantages of the device of the invention are evident. In fact, said device is initially made of a single piece that can be easily and rapidly assembled in angularly connected sections.
- The breakage of the bridges is easily and rapidly obtained with the tip of a tool, such as a screwdriver, positioned between trolley and body, pushing the trolley.
- The external border of the trolley is sufficiently long to provide a large contact surface between the trolley and the second longitudinal rib of the section.

Fig. 11 is the same view asFig. 7 , except for the fact that it shows the device in tightened condition; -
Figs. 12 - 15 are four views showing four tightening operations of the device. - Referring to the figures, the aligning device of the invention is disclosed, generally indicated with numeral (1). The aligning device (1) comprises a main body (2) and two trolleys (4) rigidly connected to the main body by means of bridges (5) that can be removed to let the trolleys (4) move with respect to the body (2). The main body (2) and trolleys (4) are made of the same material that, for example, can be a metal material. In such a case, the bridges (5) are thin weld spots made of the same material as body (2) and trolleys (4).
- The main body (2) is shaped as a square comprising two plate portions disposed at right angle. The main body (2) comprises an external border (20) and an internal border (21). The external border (20) is made of rectilinear ribs disposed at right angle.
- As shown in
Figs. 2A and 5A , the internal border (21) is tilted with respect to the external border (20) by an angle (α) from 5° to 10°, preferably 8°. - The two trolleys (4) are identical and each trolley (4) is shaped as a basically rectangular plate having the same thickness as the main body. Each trolley (4) has a slightly higher length than half length of each portion of the main body (2).
- Each trolley (4) comprises a rectilinear external border (40) and an internal border (41) adapted to face towards the internal border (21) of the man body. Advantageously, the external border (40) of the trolley is serrated or notched.
- As shown in
Figs. 2A and 5A , the internal border (41) of the trolley is tilted with respect to the external border (40) by the same angle (α) defined between external border (20) and internal border (21) of the main body. In such a way, when the internal border (41) of the trolley is in contact with the internal border (21) of the main body, the external borders (20, 40) of body and trolley are parallel. - The internal border (41) of each trolley (4) is connected with the internal border (21) of the main body by means of thin bridges (5) that can be broken easily, in such manner to separate the trolley (4) from the main body. Advantageously, four bridges (5) are provided for each trolley (4).
-
Fig. 6 shows two rectilinear sections (7) joined at right angle along a junction line (70). Also referring toFig. 7 , each section (7) is provided with a longitudinal channel (71) defined between a first rib (72) and a second rib (73). - When the trolley (4) is fixed to the body (2) by means of bridges (5), the distance between the external border (20) of the body and the external border (40) of the trolley is lower than the width of the channel (71) of the sections. In such a way, the aligning device (1) can be disposed in the channels (71) of the sections in transversal direction to the plane of lay of the sections, after joining the sections.
- Referring to
Figs. 2A and 5A , each plate portion of the main body (2) comprises two retaining fins (22) that protrude from the internal border (21) according to a plane parallel to the plane of lay of the body (2). The retaining fins (22) are rectangular and spaced. The fins (22) have an upper surface flush with the upper surface of the body (2) (seeFig. 2A ) and a lower thickness with respect to the thickness of the body (2), in such manner to form a step (23) (Fig. 5A ), basically parallel to the internal border (21). Advantageously, the step (23) is provided with serrated or notched surface. - On the lower surface of the fins (22) notches (24) are obtained (
Fig. 5B ) along lines orthogonal to the internal border (21). - Referring to
Fig. 5 , in the proximity of the end of each plate portion (2), on the internal border (21) a first notch (25) is obtained, continuing with a groove (G1) defined between an oblique border (45) of the trolley (4) and an oblique border (35) of the body. The groove (G1) is adapted to receive the tip of a tool, such as a screwdriver (8) (as shown inFigs. 8A and12 ). - Still referring to
Fig. 5 , in the central part of the internal border (21), between the two fins (22), a second notch (26) is obtained, in correspondence of a corresponding notch (46) obtained in the trolley, in such manner to generate a second groove (G2) extending from the notch (26) of the body to the notch (46) of the trolley. - Each trolley (4) comprises two retaining fins (42) that protrude from the internal border (41). The retaining fins (42) are rectangular and spaced. The fins (42) have a lower surface flush with the upper surface of the trolley (4) (see
Fig. 5A ) and a lower thickness with respect to the thickness of the trolley (4), in such manner to form a step (47) (Fig. 2A ), basically parallel to the internal border (41). - So, the fins (42) of the trolley can slide under the fins (22) of the body, preventing the possible raising of the trolley with respect to the body.
- On the border of the fins (42) a serrated surface (43) is obtained to cooperate with the serrated surface (23) of the body (2).
- On the upper surface of the fins (42) notches (44) are obtained (see
Fig. 2B ) disposed along lines orthogonal to the internal border (41), adapted to cooperate with the notches (24) of the body (2). - On the border of a fin (42) of the trolley the notch (45) is provided and disposed in register with the notch (25) of the body, in such manner to form a stop surface for the tip of a tool.
- Referring to
Figs. 1, 2 ,4 and 5 , the body (2) comprises a central through hole (28) disposed in the proximity of the corner between two plate portions, for injection and passage of glue or other waterproofing and/or sealing material. Referring toFig. 5 , on the lower surface of the body (2) channels (29) are obtained in communication with the central hole (28) to distribute glue in strategic points of the device, in such manner to obtain perfect sealing of the device to the section. - Referring to
Figs. 8A, 8B, 8C and12 - 15 , the assembly of the device (1) is disclosed. - Referring to
Figs. 8A and12 , after positioning the device (1) in the channels of the sections (7), the tip (8) of a screwdriver is inserted in the first groove (G1) between body and trolley and the screwdriver is rotated in the direction of the arrow (F1) (Fig. 13 ), in such manner to push the trolley (4) and break the bridges (5). So, the second groove (G2) is enlarged to insert the tip (8) of the screwdriver. - Referring to
Figs. 8B and14 , the tip (8) of a screwdriver is inserted in the second groove (G2) between body and trolley and the screwdriver is rotated in the direction of the arrow (F2) (Fig. 15 ), in such manner to make the internal border (41) of the trolley (4) slide on the internal border (21) of the body (2). Considering that the internal borders (21, 41) of body and trolley are tilted by an angle (α) with respect to the external borders (20, 40), the external border (40) of the trolley moves away from the external border (20) of the body, in parallel position. - Consequently, as shown in
Fig. 11 , the external border (20) of the body is engaged against the first longitudinal rib (72) of the section and the serrated or notched surface of the external border (40) of the trolley presses against the second rib (73) of the section, favoring planarity in the junction between the two sections (7). - As shown in
Figs. 9 and 10 , during the movement of the trolley (4), the fins (42) of the trolley go under the fins (22) of the body, preventing the trolley from raising and being overturned. Moreover, the serrated or notched surfaces (43, 44) of the trolley are engaged against the serrated or notched surfaces (23, 24) of the body, thus avoiding the backward travel of the trolleys (4) and consequently the loosening of the device after tightening. - Finally, when tightening is completed, as shown in
Fig. 8C , glue is injected in the hole (28) of the body, in such manner to seal the device perfectly.
