Moreover, since the support pieces 51b and 52b play the said role (function of ensuring rigidity of the pallet P), it is preferable that the length dimension is large.

Specifically, the length dimension of the support pieces 51b and 52b is a lower base in the state in which the lower base 61 is not extended in the longitudinal direction (X direction) of the pallet P (FIG. 17 (a) state). It is preferable that it is formed in the largest length dimension in the range which does not protrude from the both ends in the Y direction of (61) (range between Yu line and Yd line in FIG.). Similarly, it is preferable that the case bodies 55 and 56 are also formed in the longest length dimension in the range which is satisfactory in a structure and a stretch operation.

In addition, as shown in FIG. 24 and FIG. 25, the guide body 32a (or guide groove 33a) is formed in the lower surface part of the case body 32 (or case body 33).

Moreover, the screw rod 31a and the screw rod 31b are connected through the hollow square cylindrical connection part 36. As shown in FIG.

Moreover, as shown in FIG. 23, the screw rod 31a has the side surface (short side side) from the side surface (short side side) of the one end side (lower side side in figure) of the case body 32 to the other end side (upper side in figure). ) Is penetrated into the cylinder of the connection part 36 arrange | positioned adjacent to the side surface of the other end side of the case body 32 (the upper end part of the screw rod 31a extends to the inside of the cylinder of the connection part 36). ).

Moreover, while the screw rod 31a has a screw formed in the rod-shaped part, one end part protrudes from the side surface of the short side of the case body 32, and the annular operation part 31a1 is formed in the one end which protruded. It is.

Moreover, the fitting part 31a2 which fits (abuts) in the cylinder of the connection part 36, and slides freely in the axial direction of the connection part 36 to the upper end part (the upper part in a figure) of the screw rod 31a. ) Is formed.

And when the screw rod 31a rotates the operation part 31a1, it rotates about an axis line (rotation shaft). Moreover, when the screw rod 31a rotates as mentioned above, the connection part 36 with which the fitting part 31a2 of the screw rod 31a was fitted rotates according to the rotation.

In addition, as shown in FIG. 22, the screw rod 31b penetrates the side surface (short side surface) of the one end side (lower side side in figure) of the case body 33, and the side surface (short side of the upper end side in FIG.) Is short. Side to side).

Moreover, the screw rod 31b penetrates into the barrel of the connection part 36 arrange | positioned so that the one end side (lower end side in FIG.) May be adjacent to the side surface of the one end side of the case body 32 (the lower end part shown in FIG. 22). Extending into the barrel of the connecting portion 36).

Moreover, the fitting part 31b2 fitted in the cylinder of the connection part 36 is formed in the lower end part (lower part in the figure) of the screw rod 31b.

By this structure, when the screw rod 31a is rotated, the screw rod 31b is made to rotate in accordance with rotation of the connection part 36 which rotates accordingly.

Moreover, the other end part (the upper end part in FIG. 22) of the connection part 36 is being fixed to the side surface (short side surface side) of the one end side of the case body 33. As shown in FIG.

In addition, the movable connection part 34 (and the movable connection part 35) is provided with the through-hole through which the screw rod 31a (and the screw rod 31b) are inserted, and screwed into the screw of the said rod part in the inner peripheral part of the through-hole. The thread part is formed.

Further, the movable connecting portion 34 (see FIGS. 23 and 24) is disposed inside the case body 32, and the second pivot pin 22 in which the sliding groove is freely inserted into the guide groove 32a of the case body 32. (The 2nd axis pin 22 which connected the adjacent link members 21 comrades) is attached.

Moreover, the movable connecting part 35 (refer FIG. 22, FIG. 25) is arrange | positioned inside the case body 33, and the 2nd axis pin 22 in which sliding slidingly inserted in the guide groove 33a of the case body 33 is carried out. ) Is attached.

By the above structure, the screw rod 31b is rotated via the connection part 36 by rotating the screw rod 31a by the operation part 31a1 of the jack mechanism 30. As shown in FIG.

Thereby, the movable connection part 34 (and the movable connection part 35 which matched with the screw rod 31b) screwed to the screw rod 31a is moved, and the 2nd axis connected to the movable connection parts 34 and 35 by this is carried out. The pin 22 is moved (moved in the X direction), and the lozenges of the pantograph mechanisms 20a and 20b can be stretched and contracted (the cross angle of the link members 21 is changed so that the pantograph mechanisms 20a and 20b are Y Direction can be stretched).

And by operating the jack mechanism 30, the deck board is sandwiched between the center part of the pantograph mechanism 20, in the state which prepared the direction (direction of a long direction (X direction)) of each deck board 10. In the short direction (Y direction) of (10), each deck board 10 supported by the pantograph mechanism 20 is moved, and the space | interval of adjacent deck boards 10 is changed, and the magnitude | size of the mounting surface R is changed. There is a number.

In addition, in the above-mentioned case, the "first outer deck board 10a and the 1st inner deck board 10b" have the center part of the pantograph mechanism 20 between "the 2nd inner deck board 10d and the 2nd inside deck board 10b." The direction of movement of the outer deck board 10e "

As described above, according to the present embodiment, when the size of the surface R to be loaded is changed as in the above-described conventional technique (see FIG. 28 (b)), the edge portion of the surface R to be loaded does not become uneven. Since the mounting surface R is kept in a substantially rectangular shape (no dead space is formed), the mounting surface R can be effectively utilized.

Moreover, the pallet P of this embodiment moves the deck board 10 with the jack mechanism 30 and the pantograph jack 50, and the mounting surface R formed by the some deck board 10 is carried out. ) Size is variable.

That is, in this embodiment, since the deck board is moved by the screw type jack (jack mechanism 30 and pantograph jack 50), the deck board 10 can be moved in "millimeter unit." . That is, the size of the mounting surface R of the pallet P can be set with high precision.

In addition, in this embodiment, since the deck board 10 is moved by the screw type jack (jack mechanism 30 and the pantograph jack 50), the deck board 10 is moved by hand like a conventional technique. In comparison, no effort is required to move the deck board 10 (the burden on the operator is reduced).

In addition, in this embodiment, since the deck board 10 is moved by the screw type jack (jack mechanism 30 and the pantograph jack 50), the load surface R of the deck board 10 was loaded. In the state, the size of the mounting surface R can be changed by operating the screw jack. That is, since the size of the surface to be loaded can be finely adjusted while carrying the load on the surface R of the pallet P, the work load is reduced.

In addition, according to the jack mechanism 30 and the pantograph jack 50, since the movement operation | movement and the fixing operation | movement of the deck board 10 can be performed together (in the same operation), the troublesome locking operation like the prior art mentioned above is unnecessary. Done.

Moreover, according to this embodiment, the magnitude | size of the mounting surface R can be adjusted also in any of "long direction (the X direction) of a deck board", and "short direction (the Y direction) of a deck board".

Specifically, by operating the jack mechanism 30 of the deck board unit 1, the size R of the surface to be loaded is stretched and stretched so that the surface R is placed only in the "short direction (the Y direction) of the deck board 10". Can be fixed

Moreover, by operating the pantograph jack 50 of the base unit 5, the surface R mounted only in the "long direction (the X direction) of a deck board" can be expanded and fixed.

In addition, by operating both the jack mechanism 30 and the pantograph jack 50, the mounting surface R can be stretched and fixed in both directions of "long direction of the deck board" and "short direction of the deck board". There is a number.

That is, according to this embodiment, the mounting surface R can be adjusted so that it may become an optimal size according to the shape of the load which is to be loaded.

In addition, this invention is not limited to embodiment mentioned above, A various deformation | transformation is possible in the range of the summary.

In the above-described embodiment, the deck board 10 is displaced in the Y direction by the pantograph mechanism 20 of the deck board unit 1 and the deck board 10 by the pantograph jack 50 of the base unit 5. ) Is displaced in the X direction (displaced in two directions), but is not particularly limited thereto.

For example, as shown in FIG. 27, the deck board 10 may be displaced in the X direction only by the pantograph jack 50 of the base unit 5 without providing the pantograph mechanism in the deck board unit 1. (It may be displaced in only one direction).

In addition, in FIG. 27, the same code | symbol is attached | subjected to the structure similar to embodiment mentioned above, and an equivalent structure for convenience of description.

As illustrated, the pallet P includes a deck board unit 2 having a rectangular loading surface formed by arranging a plurality of plate-like deck boards 10 in parallel, and a base unit on which the deck board unit 2 is mounted ( 6) is provided.

Moreover, the base unit 6 is equipped with the pantograph jack 50 arrange | positioned at the center part of the pallet P, and the pair of base part 60 attached to both sides of the pantograph jack 50. As shown in FIG.

The pantograph jack 50 enables the pair of base portions 60 to reciprocate in the long direction (the X direction) of the deck board 10 with the pantograph jack 50 interposed therebetween.

In addition, the base part 60 may be comprised from the lower base 61, the sliding plate 62, the guide rail (the 1st guide rail 64, the 2nd guide rail 62b), etc. like embodiment mentioned above. It does not need to be sufficient, but just needs to be formed in rectangular plate shape.

Moreover, the deck board unit 2 comprised by the several deck board 10 hangs on the upper surface of a pair of base part 60. Moreover, all the some deck boards 10 are fixed to the base part 60 different from the deck board 10 arrange | positioned adjacent to any one of a pair of base parts.

With the above configuration, when the base portion 60 is moved in the long direction (X direction) with the pantograph jack 50, the deck board 10 moves in the long direction (X direction) in accordance with the movement. Each deck board 10 moves in the opposite direction to the adjacent deck board 10). As a result, the size of the surface to be loaded is changed.

In addition, in the above embodiment, the deck board 10 is displaced by supporting the plurality of deck boards 10 arranged in parallel with the pantograph mechanism 20 and by stretching the pantograph mechanism 20. In particular, it is not limited to this.

For example, if the size of the load is large, the number of deck boards 10 may be reduced and the distance between adjacent deck boards 10 may be increased, depending on the number of deck boards 10 (deck board 10 ), The position of the deck board 10 may be displaced by the X-shaped link mechanism instead of the pantograph mechanism 20.

In this case, for example, the link mechanism may be one in which a pair of plate- or rod-shaped arms are crossed in an X shape and the intersection portion is rotatably connected to the first axis pin 21c.

Then, one free end of the link mechanism is attached to the deck board 10 arranged on one side via the second pivot pin 22 (sliding at least one place in the longitudinal direction of the deck board 10 freely). Attached). In addition, the other free end of the link mechanism is attached to the deck board 10 arranged on the other side via the second axis pin 22 (at least one slide in the longitudinal direction of the deck board 10 Freely attached).

When the deck board 10 is three pieces, for example, the center deck board 10c2 having a guide groove (not shown) is fixed to the base unit 5, and the first pivot pin of the link mechanism is provided. Sliding 21c may be freely inserted into the guide groove.

Moreover, the deck boards 10 of both sides are fixed to the support part of the base unit 5.

By changing the crossing angle of the said link mechanism by the said structure, in the state which made the direction of the deck board 10 aligned, the deck board 10 is moved in parallel with the short direction of the deck board 10, and is adjacent. It is possible to change the size of the mounting surface R by changing the interval between the deck boards 10, respectively.

Moreover, you may make it attach a jack mechanism (for example, a screw jack mechanism like embodiment mentioned above) to the said link mechanism. In this case, the second spindle pin 22 is supported by the jack mechanism.

Then, by moving the second axis pin 22 by the jack mechanism, the crossing angle of the link mechanism can be varied (the deck board 10 is moved).

It is also possible to use a link mechanism formed by connecting a plurality of arms in a rhombus shape instead of a link mechanism formed by crossing the above-described arms in an X shape.

In this case, four arm | plate-shaped or rod-shaped arms are prepared, and a rhombus is formed by four arms (for the convenience of description, four rhombus-shaped parts shall be formed up, down, left, and right).

When four diamonds are used to form the rhombus, the pair of left and right diagonal parts are rotatably connected to the first axis pin, and the pair of upper and lower diagonal parts are connected to the second axis pin 22. Connect rotatably.

One of the left and right diagonal portions of the link mechanism is attached to the deck board 10 disposed on one end side of the plurality of deck boards via the first axis pin, and the other of the left and right diagonal portions is the first axis. It is attached to the deck board 10 arrange | positioned at the other end side among a plurality of deck boards via a pin.

In addition, a jack mechanism may be attached to the rhombus link mechanism, the second pivot pin 22 may be moved by the jack mechanism, and the crossing angle of the link mechanism may be varied (the deck board 10 may thereby be provided). Move).

Thus, the pallet P of this embodiment combines "the number, length width, and shape of the deck board 10", and "the number, length width, and shape of a pantograph mechanism and a link mechanism", and becomes "basic" The size of the mounting surface R of the pallet P ", the gap (width) of the deck board 10 arrange | positioned adjacently, and a variable distance dimension can be selected.

Moreover, in embodiment mentioned above, although the pantograph mechanism 20a, 20b is made to support the back surface of the deck board 10, it is not specifically limited to this.

For example, the pantograph mechanism 20 is attached to a position other than the back surface of the deck board 10 (upper surface of the deck board 10 or inside of the deck board 10 (inside of the board thickness direction)). It may be configured to displace the position of the deck board 10.

In the above-described embodiment, the jack mechanism 30 is attached to the pantograph mechanism 20 of the deck board unit 1, and the jack mechanism 30 moves and fixes the deck board 10 in the Y direction. Although it was performed, it is not limited to this in particular.

For example, the jack mechanism 30 may not be provided in the deck board unit 1. Even in this case, a dimensional variable pallet in which dead spaces are not formed even if the loading area is changed can be realized.

In addition, when the jack mechanism 30 is not installed, a fixing operation is required, but in this case, the operator manually stretches the lozenge of the pantograph mechanism 20, moves the position of the deck board 10, After that, the deck board 10 may be fixed by a bolt or the like.

In addition, in the above-mentioned embodiment, although the base unit 5 employ | adopted the structure which moves the pair of base part 60 by the pantograph jack 50, it is not specifically limited to this.

You may employ | adopt the structure (link mechanism) remove | excluding only the structure of the jack mechanism 57 from the pantograph jack 50 mentioned above. Also in this case, it is possible to realize a dimensional variable pallet in which dead space is not formed even if the loading area is changed.

In addition, when the jack mechanism 57 is not installed, a fixing operation is required, but in this case, the operator manually changes the crossing angle of the link member 54 to move the deck board 10 on the base portion 60. (Fixing is performed by bolts, screws, etc.).

Moreover, in the base unit 5 of embodiment mentioned above, the sliding board 62 as a support part is affixed on the lower base 61 which comprises the base part 60, and the deck board (the sliding board 62) is attached. 10), but as described above, this is only an example.

The base portion 60 may be any structure as long as it supports the deck board 10 and can move the supported deck board 10 in the short direction (Y direction) of the deck board 10. . For example, the sliding plate 62 may be omitted, and the deck board 10 directly disposed at both ends in the Y direction may be fixed to the L-shaped support bracket 71 to support the deck board 10 ( In this case, the L-shaped support bracket 71 functions as a support part).

In addition, in the above-mentioned embodiment, although the jack mechanism 30 of the deck board unit 1 and the pantograph jack 50 of the base unit 5 all use the structure of a screw type jack, it is limited to this especially. no.

For example, the base 60 of the base unit 5 (or the pantograph mechanism 20 of the deck board unit 1) may be comprised so that a hydraulic jack may be moved.

Moreover, although the case where the case bodies 32 and 33 of the jack mechanism 30 were attached to the center deck board 10c2 was shown in embodiment mentioned above, it is not specifically limited to this.

For example, the case bodies 32 and 33 may have the shape similar to the center deck board 10c2.

In addition, although the lower base 61 and the sliding plate 62 which comprise the base unit 5 are comprised by the above-mentioned embodiment, it is not specifically limited to this.

For example, the lower base 61 may be formed in the rectangular frame shape by the pipe material (metal round tube). Moreover, you may make it provide the slide mechanism (support part) which reciprocally moves freely in the above-mentioned Y direction at the said frame-shaped edge.
