While the boat is operating in a certain position, the board may be directed and extended toward the mating axis or manipulated while extending its extended position laterally to contact the mating axis. and retract (partially) again.

  These various patents describe bridges or other structures for boats, some are folding and composed of at least two sections.

  Folding bridges have the disadvantage of being heavy and bulky.

  Beyond two sections, the folded position of the various elements for example three sections making up the bridge represents a thickness that is too large.

  This type of bridge has too much space, the gateway is difficult to house on board in chests, therefore said bridge is left at the berth or on the deck of the ship.

  This docked bridge can be stolen and will be missing during stopovers during cruises.

  The invention tends to solve all these problems.

  The gangway is folding and compact.

  For this purpose, said bridge which is composed of at least two sections folds with the different sections which fit into each other, thus maintaining the thickness of the first section and the dimensions of this same section which larger and serves as a tray.

  Folding gangway composed of at least two sections hinged together about an axis perpendicular to their plane, each section is composed of a parallelepiped frame or frame provided with transverse slats which act as steps or slats that receive steps.

  The bridge is composed of at least two parallelepipedic frames hinged together around an axis and which fold into each other to limit the thickness of the bridge.

  The frames are provided with transverse steps, one at the end of the frames serves as a block.

  These steps are positioned to allow the folding of the whole and not to increase the thickness of the bridge.

  According to a preferred embodiment, the gateway is made in three sections.

  Each section with its frame is stored in one another by pivoting and embedding, the first largest section by its frame serves as a storage bin and receives the other sections.

  The first section comprises a locking angle which is located near the pivot axis of the second smaller section blocks said unfolded frame.

  The second section can receive at its free end a third section or another locking angle for the third.

  Each section comprises a slat which, located near the pivot axis of the smaller section, blocks said unfolded frame.

  According to another embodiment, the third section is articulated to the second section, it is smaller than the second section in which it is housed.

  The transverse slats of each frame of each section are arranged so that in the folded position, the slats with their step are offset so as not to increase the thickness of said folded bridge and / or to allow folding.

  According to one embodiment, the sections of the gateway are equipped with locking means.

  The locking means are of two types, one lock the deployed position of the bridge, the other the folded position of the bridge.

  Thus, it is possible to manipulate the bridge in its entire length without it folds unexpectedly since it is locked.

  Similarly, when the bridge is folded into the storage position, it can not open alone when it is handled, transported or housed in its storage box.

  These locking means are pivoting pins fixed on a frame and which pivotally lock the smaller adjacent frame.

  These locking lugs are judiciously arranged to lock the frames of the gateway in the closed position.

  At the end of the first section, is assembled by means of pins a lyre plate of triangular shape at the top of which is provided a cylindrical shank intended to cooperate in an articulated manner in a housing provided for this purpose on the edge of the deck of the boat.

  The lyre plate is fixed to the deck of the boat by a set of parts such as a screw, a housing, a stud or cylindrical shank, the assembly cooperating with an assembly base, a locking of the assembly being ensured by a quarter turn.

  The accompanying drawings are given by way of example and are not limiting of the invention. They represent only one embodiment of the invention and will make it easy to understand.

  The gateway according to the invention has many advantages.

  As shown in Figure 1, the bridge is folding and compact.

  It is composed of at least two sections in the embodiment shown in the figures, there are three sections, the section 1, the section 2, the section 3.

  FIG. 1 shows this unfolded bridge connected on the boat side by a platform 4 in the form of a lyre held by a mounting stud, on the platform side this bridge is held by balancines 5 and 6.

  In Figures 2 and 3, we understand the interest of this bridge since it is very reduced in size, in length it occupies only the length of the first section which is the largest and in thickness it occupies only 1 The thickness of the frame of a single section plus the thickness of the steps and the plate-shaped lyre.

  These technical advantages of the bridge are very clearly shown in FIGS. 1 and 3.

  The bridge is composed of at least two sections in the example shown in the figures, the bridge has three sections, first section 1, second section 2, third section 3. Said bridge folds with the different sections 1, 2, 3 which fit into each other thus preserving the thickness of a single section and the dimensions of the first largest section.

  The first section 1 thus serves as a receiving tray for the other sections.

  The gateway according to the invention is composed of at least two sections in the embodiment there are three sections 1, 2, 3 hinged together about an axis perpendicular to their plane, axis 7 for the first section 1 and the second section 2, axis 8 for the second section 2 and the third section 3. Each section is composed of a parallelepiped frame or frame provided with transverse slats 9, slats which serve as steps or which can receive steps directly 10.

  According to another embodiment not shown in the figures, the slats may be replaced by brackets. The angles receive the steps.

  Each section 1, 2, 3 with its frame is stored in one another by pivoting and embedding, the first section 1 the largest by its frame serves as a storage bin and receives the other sections 2 and 3.

  The first section 1 comprises a slat 11 located near the pivot axis 7 of the second section 2 smaller to block said unfolded frame.

  Similarly, the second section 2 can receive at its free end a third section 3. It then comprises a locking angle 12 located near the axis of articulation 8. This locking angle 12 comes to block the frame of section 3 when the bridge is unfolded.

  This third section 3 is articulated to the second section 2, it is smaller than the second section 2 in which it is housed, see Figures 5, 6,7 and 8.

  The transverse slats 9 of each frame of each section 1, 2, 3 are arranged so that in the folded position, the slats 9 or the steps 10 they carry are offset so as not to increase the thickness of said folded gangway and / or allow folding.

  FIG. 4 highlights the three sections 1, 2 and 3 with their slats 9. These slats bear steps 10 which are represented in gray according to whether the slats or steps 10 of the first section 1, the second section 2 or the third section 3 and so as to show how in the folded position, these slats 9 or steps 10 are offset with respect to each other.

  FIGS. 5, 6, 7 and 8 show that said slats 9 are offset relative to one another so as not to increase the thickness of the whole of the bridge and to allow the folding of the bridge.

  Thus, the frame section 3 with its frame is engaged in the frame 25 of the second section 2.

  These two sections 2 and 3 folded and engaged one into the other engage in the first section 1 inside its frame while the plate-shaped lyre 4 is folded over the whole as shown in Figure 8.

  Figure 9 shows in detail a plan view of the first section 1.

  FIG. 10 represents a side view of the first section 1 with the lyre-shaped plate 4 which can fold in the direction of the arrow F1.

  Figures 11 and 12 show the section 2 with its frame, its slats and its steps and its two axes of articulation 7 and 8.

  Figure 11 is a plan view of the section 2.

  FIG. 12 is a view according to FIG. 11, viewed from the side, of section 2.

  FIGS. 13 and 14 are views of the third section 3 showing its slats 9, its steps 10 and its hinge or pivot axis 8.

  Figures 15 to 23 highlight the attachment device and articulation between the bridge and the deck of the ship.

  The deck of the ship 23 has a housing near its edge, housing which can receive an assembly base 13. This base assembly 13 is shown in Figures 22, 23 by a sectional view, it is also shown in FIG. Figure 18 seen from above.

  This assembly base is fixed by three screws 14 in the figures.

  This assembly base comprises a housing 17.

  At the plate 4 in the form of a lyre of the bridge it includes a screw 15 and a washer 16.

  This screw 15 and this washer 16 make it possible to fix a stud 18 or cylindrical shank intended to cooperate with the housing of the assembly base 13.

  The upper part of the stud 18 comprises a collar 19 with an escapement 20 which will make it possible to obtain, in cooperation with a nut 21, either a lock in a groove 22 provided for this purpose in this collar, or an exhaust when the user has operated. a quarter of a turn to release the stud or the cylindrical tail 18.

  This nut 21 is fixed to the base assembly 13 on the deck of the boat by the screws 14.

  As shown in Figure 23, it is understood that having positioned the stud or the cylindrical shank 18 of the plate 4 in the form of a lyre of the bridge, can, having made a quarter turn, lock in the vertical direction so that it can not separate from the bridge. To dismount the bridge, simply operate a quarter turn to release the flange of the nut 21 and remove the stud or cylindrical shank 18. lo

  According to one embodiment, the different sections 1, 2 and 3 of the gateway are equipped with locking means.

  These locking means are of two types, one locking the gateway in the deployed position so as to adjust it with respect to the dock and adjust the two balancines 5, 6.

  The other locking means lock the folded gateway so that it does not open unexpectedly during handling or when stored for example in a trunk of the boat.

  The locking means of the gateway are referenced by the letters io open lock, open lock 1 VO1 which blocks the gateway in the open position by blocking the section 1 and the section 2.

  The locking means 2 V02 which block at the same time the section 2 and the section 3.

  The closed locking means referenced VF block sections 1, 2 and 3 when the gateway is closed.

  They are found in FIG. 4, referenced VF1, which blocks section 1 and section 2, VF2, which block section 3.

  These locking means as shown in the figures are pivoting pins fixed on a frame of the section 1, 2 or 3 and pivotally block the smallest adjacent frame. he
