Description

  The present invention relates to an aircraft pallet device used when cargo or a container is loaded in an aircraft cargo compartment, and more specifically, is suitable for any of two types of cargo loading rails having different rail widths according to the fuselage width of the aircraft. Thus, the present invention relates to an aircraft pallet apparatus that can mount a long cargo or a long container.

A conventional aircraft pallet is formed in a rectangular shape having different vertical and horizontal dimensions, and guides on both sides of a set of two cargo loading rails laid in the longitudinal direction on the floor in the cargo compartment of the aircraft. The members are engaged and configured to be movable and fixed along the rail, and cargo or equipment is placed on the upper surface thereof (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 8-310496

  That is, as shown in FIG. 13 (A), the pallet 1 has a side dimension (for example, horizontal dimension) of a (about 270 cm) and the other side dimension (for example, vertical dimension). Formed in a rectangular shape b (about 220 cm), claws 2, 2 '; 3, 3' as guide members are provided on the two opposing sides. The pallet 1 having such a size is intended for a cargo or container having a size of a × b or less on the upper surface thereof, and is sometimes called a standard pallet.

  On the other hand, on the floor in the cargo compartment of the aircraft, a set of two rails 4 having a rail width of a width (for example, about 270 cm) is provided as shown in FIG. 14 (A) according to the fuselage width of the aircraft. As shown in FIG. 14B, there are aircraft having a cargo loading rail 5a and an aircraft having a rail width of width b (for example, about 220 cm) and the cargo loading rail 5b.

  In such a case, when the cargo or container is loaded in the cargo compartment of the aircraft in which the cargo mounting rail 5a shown in FIG. 14A is laid, the pallet 1 shown in FIG. ), The side of dimension a is turned vertically and the claws 3, 3 'on both sides are engaged and mounted on the cargo mounting rail 5a in the cargo compartment as shown in FIG. And may be fixed with a fixing tool (not shown).

  When loading cargo or containers in the cargo compartment of an aircraft in which the cargo mounting rail 5b shown in FIG. 14B is laid, the pallet 1 shown in FIG. 13A is shown in FIG. 13C. In this state, the side of the dimension b is set in the vertical direction, and the claws 2 and 2 'on both sides are engaged and mounted on the cargo mounting rail 5b in the cargo compartment, and the fixing is omitted at an appropriate position. Fix it with tools. In this way, the pallet 1 called a standard pallet is used by freight mounting rails 5a and 5b having two types of rail widths a and b by rotating one dimension a and the other dimension b by 90 degrees. Any of these can be shared.

  However, when the size of the cargo or container to be placed on the upper surface becomes larger than the above-described dimension a × b, for example, the length of the cargo or container becomes larger than the dimension a shown in FIG. When the pallet 1 is a long object having a dimension c (c> a), the pallet 1 has a vertical dimension of a (for example, about 270 cm) and a horizontal dimension of c as shown in FIG. It is necessary to use the long pallet 1a or the long pallet 1b having a vertical dimension of b (for example, about 220 cm) and a horizontal dimension of c as shown in FIG. In this case, the long pallet 1a becomes a dedicated pallet corresponding to the cargo mounting rail 5a shown in FIG. 14 (A), and the long pallet 1b corresponds to the cargo mounting rail 5b shown in FIG. 14 (B). It becomes a dedicated palette. Therefore, it is not possible to mount a long cargo or a container with a long size by adapting to any of the two types of cargo mounting rails 5a and 5b having different rail widths according to the fuselage width of the aircraft. It was.

  Therefore, the present invention addresses such a problem and adapts it to any of two types of cargo-mounted rails having different rail widths depending on the fuselage width of the aircraft. An object of the present invention is to provide an aircraft pallet apparatus that can mount containers.

  In order to achieve the above object, an aircraft pallet apparatus according to the present invention is formed in a rectangular shape having a vertical dimension and a horizontal dimension different from each other, and laid in a longitudinal direction on a floor surface in an aircraft. A plurality of pallets that are configured to be movable and fixed along the rails with guide members on both sides engaged with the cargo mounting rail, and attached to the upper surface side of the plurality of pallets, and at least two The pallet is formed to have a length approximately equal to or longer than the sum of the vertical and horizontal dimensions of the pallet, and is provided at a long base on which the cargo or container is placed on the upper surface, and at substantially the center of each pallet. And a pivot shaft that fits into a hole formed at a predetermined position on the central axis in the longitudinal direction of the gantry and pivotally couples each pallet to the gantry.

  With such a configuration, a plurality of pallets formed in a rectangular shape having different vertical dimensions and horizontal dimensions are placed on both sides of a pair of cargo mounting rails laid in the longitudinal direction on the floor surface in the aircraft. Engage the guide members on the side and combine them so that they can be moved and fixed along the rails. They are attached to the upper surface of the pallets, and the length is the sum of the vertical or horizontal dimensions of at least two pallets. A cargo or container is placed on the upper surface of a long pedestal formed to have a length approximately equal to or longer than that of the pallet, and a pivot shaft provided at a substantially central part of each pallet is set at the center in the longitudinal direction of the pedestal. Each pallet is rotatably coupled to the mount by fitting in a hole formed at a predetermined position on the shaft.

  Further, stopper means for fixing the rotation of each pallet with respect to the gantry is provided on the upper surface of each pallet and the lower surface of the gantry. Thereby, the rotation of each pallet is fixed with respect to the gantry by the stopper means provided on the upper surface of each pallet and the lower surface of the gantry.

  Further, the hole formed at a predetermined position of the gantry is formed by extending a predetermined length along the longitudinal central axis of the gantry, and each pallet is movable in the longitudinal direction with respect to the gantry. Is. Thereby, each pallet is movable in the longitudinal direction with respect to the gantry through a long hole formed by extending a predetermined length along the longitudinal central axis of the gantry.

  According to the first aspect of the present invention, the pivot shaft provided at the substantially central portion of the plurality of pallets is fitted into a hole formed at a predetermined position on the central axis in the longitudinal direction of the long frame. By connecting each pallet so that it can rotate with respect to the above frame, each pallet can be rotated corresponding to two types of cargo loading rails having different rail widths according to the fuselage width of the aircraft. Each pallet can be moved and fixed along the rail by engaging with each of the mounting rails. Therefore, by using the aircraft pallet apparatus of the present invention, a long cargo or a container with a long size can be adapted to any of two types of cargo mounting rails having different rail widths depending on the fuselage width of the aircraft. It can be mounted.

  Moreover, according to the invention which concerns on Claim 2, rotation of each pallet can be fixed with respect to the said mount with the stopper means provided in the upper surface of each pallet, and the lower surface of the mount. Therefore, it is possible to position each pallet in the front-rear and left-right directions with respect to the long base, and to transmit a load when moving the base on the cargo mounting rail.

  Furthermore, according to the invention according to claim 3, each pallet moves in the longitudinal direction with respect to the gantry by a long hole formed by extending a predetermined length along the longitudinal center axis of the gantry. Can be possible. Therefore, in the longitudinal direction of the long gantry, the intervals between the plurality of pallets can be widened or narrowed, or the plurality of pallets can be shifted to one side.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a diagram showing an embodiment of an aircraft pallet apparatus according to the present invention. This aircraft pallet apparatus is used when a long cargo or a long-sized container is mounted in an aircraft cargo compartment, and includes a plurality of pallets 10a and 10b, a gantry 11, and a pivot shaft 12. Be prepared.

  The pallets 10a and 10b are used to mount cargo or containers on the upper surface side together with a later-described gantry 11, and are formed in rectangular shapes having different vertical and horizontal dimensions, and are laid in the longitudinal direction on the floor surface in the aircraft. Guide members on both sides are engaged with the set of two cargo loading rails so that they can be moved and fixed along the rails. That is, the pallets 10a and 10b are formed in a rectangular shape in which the dimension of one side is a (for example, about 270 cm) and the dimension of the other side is b (for example, about 220 cm), Claws 13, 13 '; 14, 14' as guide members are provided on the two opposing sides.

  On the other hand, according to the fuselage width of the aircraft, on the floor in the cargo compartment of the aircraft, as shown in FIG. 3 (A), a set of two rails 4 has a rail width of width a (for example, about 270 cm). As shown in FIG. 3B, there are aircraft having a rail b of width b (for example, about 220 cm) and laying the cargo mounting rail 5b. In this case, the claws 14 and 14 'on both sides engage with the cargo mounting rail 5a with the side of the dimension a of the pallets 10a and 10b in the vertical direction, and the side of the dimension b in the vertical direction. In this state, the claws 13 and 13 'on both sides are engaged with the cargo mounting rail 5b.

  A gantry 11 is attached to the upper surface side of the plurality of pallets 10a and 10b. The gantry 11 is used for placing a cargo or container (see reference numeral 15 in FIG. 2) on the upper surface thereof, and the vertical dimension (for example, a) or the lateral dimension (for example, b) of at least two pallets 10a and 10b. It is formed in a long dimension that is approximately equal to or longer than the added length. That is, in the example of FIG. 1, the vertical dimension of the gantry 11 is substantially the same as b, and the horizontal dimension is 2a or more than 2b.

  A pivot shaft 12 is provided at a substantially central portion of each of the pallets 10a and 10b. The pivot shaft 12 rotatably couples the pallets 10a and 10b to the gantry 11, and a predetermined position on the central axis in the longitudinal direction of the gantry 11, for example, both side portions in FIG. Are fitted in two holes formed respectively. That is, as shown in FIG. 2, a circular hole 16 is formed in the lower surface of the gantry 11, and a pivot shaft 12 projects from the upper surface of each pallet 10 a, 10 b, and the pivot shaft 12 is fitted into the hole 16. The protrusions at the upper end of the pivot shaft 12 are engaged with each other so as to be prevented from being detached.

  As shown in FIG. 2, stopper pins 17 are projected upward at the positions of the four apexes of the square centering on the pivot shaft 12 on the upper surfaces of the pallets 10 a and 10 b, respectively. Circular locking holes 18 are formed at the positions of the four apexes of the square corresponding to the stopper pins 17 on the lower surface. Then, the pallets 10a, 10b are lifted up and the stopper pins 17 are inserted into the locking holes 18 of the gantry 11, thereby preventing the pallets 10a, 10b from rotating. The stopper pin 17 and the locking hole 18 constitute stopper means for fixing the rotation of the pallets 10a and 10b with respect to the gantry 11. In FIG. 2, reference numeral 19 indicates a pallet fixing device that stops the pallets 10 a and 10 b from moving up and down with respect to the gantry 11.

  A state in which the aircraft pallet apparatus configured in this manner is engaged with and mounted on a cargo mounting rail in an aircraft cargo compartment will be described with reference to FIG. First, as shown in FIG. 3A, the pallets 10a and 10b that are pivotally coupled to the gantry 11 by the pivot shaft 12 are removed from the pallet fixing device 19 shown in FIG. It is rotated in the vertical direction and fixed by the stopper means (17, 18), and the axis is aligned with the cargo mounting rail 5a having a rail width of width a (for example, about 270 cm) and moved as indicated by an arrow A. If the claws 14 and 14 'on both sides are engaged and mounted on the cargo mounting rail 5a, moved to an appropriate position and fixed with a known fixing tool (hook-shaped metal fitting) provided on the floor surface. Good.

  3B, the pallets 10a and 10b, which are similarly coupled so as to be rotatable by the pivot shaft 12, are rotated so that the side of the dimension b is in the vertical direction, and the stopper means is provided. (17, 18), move to the cargo loading rail 5b having a rail width of width b (for example, about 220 cm) as indicated by the arrow B, and move the claws 13, 13 'on both sides to the cargo loading. What is necessary is just to engage and mount on the rail 5b, move to an appropriate position, and fix with a known fixing tool (hook-shaped metal fitting) provided on the floor surface. By using such an aircraft pallet device, it can be adapted to any of the two types of cargo-mounting rails 5a and 5b having different rail widths a and b depending on the fuselage width of the aircraft. It is possible to mount a container of a scale size.

  However, even the aircraft pallet apparatus having the above-described configuration has room for improvement in the following points. That is, as shown in FIG. 4, when the interval between the pallets 10a and 10b rotatably coupled to the gantry 11 by the pivot shaft 12 is narrow, the other pallet 10b is fixed with the one pallet 10a fixed. If the rotation is attempted, the corner portion of the other pallet 10b hits a part of the one pallet 10a so that the rotation is impossible. Therefore, as shown in FIGS. 3 (A) and 3 (B), it can be adapted to one of the two types of cargo-mounting rails 5a and 5b having different rail widths. And cannot be installed.

  As shown in FIG. 5, when the interval between the pallets 10 a and 10 b coupled to the gantry 11 by the pivot shaft 12 is too wide, the outer end portions of the two pallets 10 a and 10 b at both side ends of the gantry 11. Protrudes outward from the gantry 11 and comes close to the end of each pallet 10a, 10b coupled to another gantry 11 adjacent to the gantry 11. In this case, the distance d between the outer end of one gantry 11 and the opposite outer end of the other gantry 11 adjacent to each other must be increased, and wasteful space is used in the cargo compartment of the aircraft. Become.

  Therefore, in order to improve such a point, the hole 16 formed at a predetermined position of the gantry 11 is formed to extend by a predetermined length along the central axis in the longitudinal direction of the gantry 11, and each pallet 10 a and 10 b are movable in the longitudinal direction with respect to the gantry 11. That is, as shown in FIG. 6, the hole 16 formed on the both sides of the lower surface of the gantry 11 is extended by a predetermined length along the central axis in the longitudinal direction of the gantry 11. 16 ', and the pivot shaft 12 of each pallet 10a, 10b is fitted in the long hole 16'. In FIG. 6, only one pallet 10a is shown, and the other pallets are omitted.

  Accordingly, as shown in FIG. 4, even if the interval between the pallets 10a and 10b rotatably coupled to the gantry 11 is narrow, the length of the gantry 11 can be reduced as shown in FIG. The pallets 10a and 10b connected to the holes 16 'by the pivot shaft 12 are moved in the directions of arrows C and D by sliding the respective pivot shafts 12 outward in the long holes 16'. Increase the interval of 10b. In this state, the pallets 10a and 10b can be rotated, for example, 90 degrees without hitting them. After that, as shown in FIG. 7B, the pallets 10a and 10b are moved in the directions of arrows E and F by sliding the respective pivot shafts 12 inwardly in the long holes 16 '. , 10b is narrowed. As a result, the problems as described above are improved, and as shown in FIGS. 3 (A) and 3 (B), it is adapted to any of the two types of cargo mounting rails 5a and 5b having different rail widths. The pallet device can be engaged and mounted.

  In the state shown in FIG. 7B, since the pallets 10a and 10b approach each other and the interval between them becomes narrow, the outer end of a certain gantry 11 as shown in FIG. It is not necessary to increase the distance d between the opposing outer ends, and useless space is not used in the cargo compartment of the aircraft. Further, in the state shown in FIG. 7B, since the pallets 10a and 10b approach each other and the distance between the pallets 10a and 10b decreases, the overall length of the aircraft pallet apparatus can be shortened, and a hangar or warehouse on the ground can be used. It is possible to save space for storage or loading when storing in a vehicle or when transporting on the ground with a transport vehicle.

  Next, as shown in FIGS. 6 and 7, refer to FIGS. 8 and 9 for the procedure of rotating and moving the pallets 10 a and 10 b coupled to the long hole 16 ′ of the gantry 11 by the pivot shaft 12. To explain. First, in FIG. 8A, the two pallets 10a and 10b are positioned with respect to the gantry 11 so that the side of the dimension a is in the vertical direction, and are rotated by the stopper means (17 and 18) shown in FIG. It is assumed that the movement is fixed and the pallet fixing device 19 is operated so as not to move up and down. In this state, as shown in FIG. 8B, the two pallets 10 a and 10 b are in a position lifted upward with respect to the gantry 11.

  Next, in FIG. 8D, the pallet fixing device 19 shown in FIG. 2 is removed, the vertical movement of the two pallets 10a and 10b with respect to the gantry 11 is released, and the pallets 10a and 10b are moved relative to the gantry 11. By moving downward as indicated by an arrow G, the stopper pins 17 of the pallets 10a and 10b are pulled out from the locking holes 18 of the gantry 11. Thereby, each said pallet 10a, 10b can move and rotate. At this time, the planar state of the two pallets 10a and 10b is exactly the same as the state of FIG. 8A, as shown in FIG. 8C.

  Next, in FIGS. 8E and 8F, the pallets 10a and 10b connected to the long holes 16 'of the gantry 11 by the pivot shaft 12 are connected to the outer sides of the respective pivot shafts 12 in the long holes 16'. And move in the directions of arrows C and D to widen the interval between the pallets 10a and 10b. Thereafter, the pallets 10a and 10b rotatably coupled to the gantry 11 by the pivot shaft 12 are rotated 90 degrees as indicated by arrows H and J, respectively, as shown in FIG. Accordingly, as shown in FIGS. 9A and 9B, the two pallets 10 a and 10 b are positioned with respect to the gantry 11 so that the side of the dimension b is in the vertical direction.

  Next, in FIGS. 9C and 9D, the pallets 10a and 10b connected to the long holes 16 'of the gantry 11 by the pivot shaft 12 are connected to the inner sides of the respective pivot shafts 12 inside the long holes 16'. And slides in the direction of arrows E and F to narrow the interval between the pallets 10a and 10b.

  Thereafter, in FIG. 9F, the pallets 10a and 10b are moved upward with respect to the gantry 11 as indicated by the arrow K, and the pallets 10a and 10b are inserted into the locking holes 18 of the gantry 11 shown in FIG. Insert the stopper pin 17. Moreover, the vertical movement of the two pallets 10a and 10b with respect to the gantry 11 is fixed by the pallet fixing device 19 shown in FIG. As a result, the vertical movement and rotation of the pallets 10a and 10b are fixed. At this time, as shown in FIG. 9E, the planar state of the two pallets 10a and 10b is fixed so that the side of the dimension b is in the vertical direction.

  8A to 8F and FIGS. 9A to 9F, the side of the dimension a of each pallet 10a, 10b is positioned in the vertical direction from the side of the dimension b. It can be arbitrarily changed until the side is positioned in the vertical direction. In contrast to the above, when changing from a state in which the side of dimension b is positioned in the vertical direction to a state in which the side of dimension a is positioned in the vertical direction, the same procedure as described above may be used. Therefore, in the aircraft pallet apparatus, the width dimension (interval between claws 13, 13 '; 14, 14') of the pallets 10a, 10b engaged with the cargo mounting rails 5a, 5b can be arbitrarily switched. Therefore, it is possible to mount a long cargo or a container having a long size by adapting to any of the two types of cargo mounting rails 5a and 5b having different rail widths according to the fuselage width of the aircraft. it can.

  FIG. 10 is a plan view showing another embodiment of the aircraft pallet apparatus of the present invention. In this embodiment, a plurality of circular locking holes 18 formed in the lower surface of the gantry 11 are formed for one of the stopper pins 17 protruding from the upper surfaces of the pallets 10a and 10b. That is, in FIG. 2, two locking holes 18, 18 'are formed at appropriate intervals for each stopper pin 17 protruding from the four corners of each pallet 10a, 10b. In this case, four locking holes 18, 18,... Located at the four vertexes of the square form one set, and four locking holes 18 ′, 18 ′, located at the four vertexes of the other square. ... is another set. When the pallets 10a and 10b are moved in the longitudinal direction using the long holes 16 'of the gantry 11, the stopper pins 17 are inserted into either of the two sets of the locking holes 18 or 18'. The positions for fixing the pallets 10a and 10b can be appropriately selected. Note that three or more locking holes 18 may be formed for one stopper pin 17. In this case, the positions for fixing the pallets 10a and 10b can be increased.

  FIG. 11 is an explanatory view showing another embodiment for fixing the aircraft pallet apparatus of the present invention in the cargo compartment of an aircraft. In this embodiment, the rail length L of the cargo mounting rails 5a and 5b laid in the cargo compartment is extremely limited for engaging and fixing the pallets 10a and 10b of the plurality of mounts 11a, 11b and 11c. However, the length M of the space in the cargo compartment is devised for fixing in the case where it is larger than the rail length L. In this case, in FIG. 11B, the middle frame 11b is fixed at the center position with respect to the corresponding pallets 10a and 10b, and the left and right frames 11a and 11c are respectively fixed with respect to the corresponding pallets 10a and 10b. Fix the left and right side edges together. That is, the left gantry 11a is fixed with the left end approaching the cradle as shown by the arrow P, and the right gantry 11c is fixed with the right end approaching the cradle as shown by the arrow Q. As a result, as shown in FIG. 11A, for example, a space R between the container 15b mounted on the middle frame 11b and the container 15c mounted on the right frame 11c is increased. R can be secured as a working space between containers. A space R similar to the above is also formed between the container 15a mounted on the left gantry 11a.

  FIG. 12 is a plan view showing still another embodiment of the aircraft pallet apparatus of the present invention. In this embodiment, three or four pallets 10a, 10b, 10c, and 10d are rotatably coupled to one long frame 11 '. First, regarding the aircraft pallet apparatus 20a in which three pallets 10a, 10b, and 10c are coupled to one long gantry 11 ', the pallet 10b in the middle of the gantry 11' is laterally moved by a pivot shaft 12b. The left and right pallets 10a and 10c are coupled so as to be able to rotate without moving, and the respective pivot shafts 12a and 12c are fitted into the corresponding long holes 16a and 16c of the gantry 11 ', respectively. It is connected so that it can move laterally in the direction.

  An aircraft pallet apparatus 20b in which four pallets 10a, 10b, 10c, and 10d are coupled to one long gantry 11 'is provided on the outer side of the three pallets 10a, 10b, and 10c. The four pallets 10d are pivotably coupled so that the pivot shafts 12d can be fitted into the corresponding long holes 16d of the gantry 11 'and can further move laterally in the direction of the arrow D'. In this case, the long hole 16d for the lateral movement of the fourth pallet 10d is longer than the long holes 16a, 16c for the lateral movement of the first or third pallet 10a, 10c. Thereby, for example, the third pallet 10c and the fourth pallet 10d can be prevented from colliding with each other at adjacent ends. Note that five or more pallets may be coupled to one long gantry 11 'according to the situation in the cargo compartment of the aircraft.
