The positioning part 10 is movable in the planar direction within the range of the gap 5b. By inserting at least one spacer 31 into a region corresponding to the space 5b inside the mounting opening 5a, the position of the positioning portion 10 in the planar direction can be adjusted.

The positioning portion 10 may be formed by a separate member from the mounting opening 5a, as will be described later, or may be formed integrally with a part of the mounting opening 5a. Although detailed description is omitted, for example, the positioning portion 10 may be connected to the inner wall portion of the mounting opening 5a by an elastic member (eg, a compression coil spring, a rubber material, etc.) so that the positioning portion 10 can move in the planar direction.

As shown in the example of FIG. 5, when the positioning portion 10 is formed by a separate member from the mounting opening portion 5a, the spacer 31 is first inserted into the mounting opening portion 5a and into which the positioning portion 10 is inserted. Then, it is inserted into the region where the gap 5b is formed. Next, the positioning portion 10 is inserted into the mounting opening portion 5a with the space 5b substantially filled with the spacers 31. As shown in FIG. Moreover, when the positioning part 10 is formed integrally with the mounting opening 5a, the spacer 31 is inserted into the already formed space 5b. Each form of the spacer 31 will be described later, but the procedure for inserting the spacer 31 is the same.

The C part is the movable mounting part 9 in which the mounting part 5 can move in the width direction. It should be noted that the configuration of the four mounting portions 5 is not limited to the examples of combinations shown from A to D, and arbitrary combinations are possible. For example, the configuration may be such that all of the four locations are A and D, or one of the four locations may include the mounting portion 5 in which the gap 5b is not formed.

As shown in FIG. 5( a ), the loading trailer 1 can directly place a load 80 on the mounting member 16 that is the positioning portion 10 . When the load 80 has a supporting surface opening 82, which is a specific portion, the positioning convex portion 16a of the mounting member 16 is inserted. When the load 80 has the load convex portion 83 that is the specific portion, it is inserted into the shaft hole 16 d of the mounting member 16 . Further, as shown in FIG. 6(a), when the loading trailer 1 is provided with a fixing device 6, which will be described later, and the load 80 is provided with a supporting surface opening 82, which is a specific portion, the positioning convex portion 16a is inserted and further The movement in the vertical direction is restricted by the fixing device 6 . That is, the positioning portion 10 is configured such that the positioning convex portion 16 a or the shaft hole 16 d engages with the supporting surface opening portion 82 or the load convex portion 83 , which is the specific portion of the load 80 , thereby determining the mounting position of the load 80 . is determined. In the example shown in FIG. 5A, the positioning protrusion 16a and the support surface opening 82 are rectangular in plan view, but may be of other shapes.

The mounting member 16 includes a top surface portion 16e mounted on the upper surface of the eaves portion 21m of the mounting pipe portion 21 and a body portion 16f inserted into the mounting pipe portion 21 with respect to the mounting opening portion 5a. The space 5b is formed between the inner wall side of the mounting tube portion 21 and the outer wall side of the trunk portion 16f. As shown in FIG. 5 and the like, the trunk portion 16f is formed in a prism shape, and includes a width direction surface 16p formed in the direction along the width direction and a longitudinal direction surface 16q formed in the direction along the longitudinal direction.

As shown in FIG. 5B and the like, the mounting opening 5a has a substantially rectangular shape with a longitudinal dimension of 5n and a widthwise dimension of 5m. The mounting member 16 forming the positioning portion 10 has a substantially rectangular shape with a longitudinal dimension of 16n and a widthwise dimension of 16m. The gap 5b is the difference between the longitudinal dimension 5n and the longitudinal dimension 16n and the difference between the widthwise dimension 5m and the widthwise dimension 16m.

As shown in FIGS. 5 to 7 and 15, the mounting tube portion 21 is provided with spacer stoppers 23 below the mounting opening 5a. As shown, at least one lower end of spacer 31 rests on spacer stopper 23 .

Next, the configuration of the mounting tube portion 21 will be described with reference to FIG. 15 and the like. The mounting tube portion 21 is configured by a combination of a total of four plates, two first tube portion plates 21a and two second tube portion plates 21b. The first tube plate 21a and the second tube plate 21b are formed with a convex portion 21e and a concave portion 21f, respectively. It is formed. A plurality of stopper holes 21g are formed in the first tube portion plate 21a and the second tube portion plate 21b below the upper end portion where the mounting opening portion 5a is formed. A protrusion 23e and a recess 23f are formed around the spacer stopper 23, and the protrusion 23e is inserted into the stopper hole 21g. A threaded shaft hole 23a is formed in the center of the spacer stopper 23, and a cylindrical threaded shaft tube 26 or the like is inserted as shown in FIG.

As shown in FIG. 4 and the like, one surface of the mounting tube portion 21 is attached to a width direction frame 22 that constitutes the base 2 . One surface of the mounting tube portion 21 may be attached to the longitudinal frame 24 that constitutes the base 2 shown in FIG. As shown in FIGS. 2 and 3, a reinforcing rib 21c is formed on the mounting tube portion 21, and is coupled to the width direction frame 22 and the like to maintain strength.

As shown in FIG. 4, the lever holding plate 21h is fastened to the mounting tube portion 21 with bolts 21n. Each member corresponds to a fixing device 6, which will be described later, and its function will be described later.

<Overall Configuration of Loaded Trailer 1 and Effect of Spacer 31>
As described above, the structure of the loading trailer 1 and the spacer 31 solves the following problems and produces effects. A conventional example is disclosed, for example, in Patent Document 1 (Japanese Unexamined Patent Publication No. 7-52702), which is a prior art document. Since the splints, which are supporting members for supporting the column part of the building unit, are fixed and supported by the loading platform via these four splinting posts, the size of the load that can be loaded on the loading platform of the truck is fixed. That is, trucks corresponding to the size of the load are manufactured, and if the size is different, it is necessary to change the position of the splints and fix them, resulting in poor productivity and lack of flexibility.

On the other hand, in the loading trailer 1 , the specific portions of the load 80 , such as the support surface openings 82 and the load protrusions 83 , can be placed on a plurality of placement portions 5 . As shown in FIGS. 3 to 13, the positioning portion 10 of the mounting portion 5 is positioned in the plane direction by inserting the spacer 31 into the region corresponding to the space 5b inside the mounting opening portion 5a. is adjustable. The positioning portion 10 is adjusted to the position of the support surface opening 82 or the load convex portion 83 which is a specific portion of the load 80 . Therefore, the load trailer 1 can mount the load 80 even when the size and mounting position of the load 80 in the plane direction change. That is, the position for positioning the load 80 can be changed according to the size of the load 80 . Furthermore, since the position of the positioning portion 10 in the plane direction of the loading trailer 1 can be adjusted, the mounting portion 5 and the specific portion of the load 80, such as the support surface opening portion 82 or the load convex portion 83, can be adjusted. Manufacturing errors with respect to position can be absorbed.

As shown in FIGS. 5 to 13 , the planar position of the positioning portion 10 on the mounting portion 5 can be finely adjusted by the spacer 31 . The spacer 31 can be adjusted by using a member having a certain thickness as an example, and combining a plurality of members. Alternatively, members of different thicknesses can be used and adjusted by one or a combination of several. The gap 5b may be formed in both the longitudinal direction and the width direction so that the positioning portion 10 can be formed in either direction and the position thereof can be adjusted, or can be formed in only one direction so that the position can be adjusted in one direction. It's okay. It can be adapted according to the load 80 . For example, when a plurality of types of loads 80 are to be loaded, the stacking position in the longitudinal direction changes and the width direction is constant, the gap 5b may be formed only in the longitudinal direction. If the load 80 changes both in the longitudinal direction and the width direction, the gap 5b may be formed in both directions. Detailed examples and effects will be described later.

Further, as shown in FIGS. 3 to 7, 10, 18, and 19, the positioning portion 10 is a mounting member 16 that can be attached to and detached from the mounting opening portion 5a. Therefore, the mounting member 16 can easily adjust the position of the positioning portion 10 by mounting the mounting member 16 after inserting the spacer 31 into the mounting opening 5a. As will be described later, the spacer 31 can adopt various forms, and the adjustment direction in the plane direction of the positioning portion 10 in the mounting portion 5 can be selected from either the width direction or the longitudinal direction, or both. is. In that case, the positioning part 10 inserted in the mounting opening 5a needs to change the shape of the plane direction. On the other hand, since the positioning part 10 is a mounting member 16 that can be attached to and detached from the loading opening 5a, it can be attached to various loads 80 by appropriately changing the form or by preparing a plurality of forms in advance. It becomes available.

Further, as shown in FIGS. 5 and 15, the mounting tube portion 21 has a spacer stopper 23 below the mounting opening 5a. Therefore, the mounting state of the spacer 31 can be stabilized in the process of inserting the spacer 31 into the mounting opening 5a.

In addition, when the spacer 31 is only a rectangular parallelepiped flat spacer 32, the flat spacer 32 can be inserted singly into the gap 5b, or a plurality of the flat spacers 32 can be inserted in combination. Furthermore, if the planar spacer 32 is made of a magnetic material, it can be fixed in advance to the inner wall of the mounting tube portion 21 or to the body portion 16f of the mounting member 16, thereby allowing the mounting member 16 to be attached to the mounting opening 5a. It is possible to prevent the planar spacer 32 from collapsing during insertion. Alternatively, the flat spacer 32 can be adhered to the inner wall of the mounting tube portion 21 or to the trunk portion 16f of the mounting member 16 to achieve the same effect.

<Structure and effect in each example of spacer 31>
Next, with reference to FIGS. 5 to 13, configuration examples of the spacers 31 provided on the loading trailer 1 and their effects will be described. The example shown in FIG. 5 shows the case where all of the spacers 31 are planar spacers 32 having rectangular parallelepiped shapes. Between the inner wall portion of the mounting tube portion 21 and the body portion 16f of the mounting member 16, a gap 5b is formed in the longitudinal direction and the width direction. The planar spacer 32 may be inserted in advance into the mounting opening 5a or may be attached in advance to the trunk portion 16f. In the example shown in FIG. 5, the space 5b is formed around the body portion 16f of the mounting member 16 on all four sides. Adjust the mounting position of the member 16 .

The planar spacer 32 may not stand on its own, and may fall down with its lower end placed on the spacer stopper 23 . Therefore, for example, the planar spacer 32 may be formed of a magnetic material and joined to the inner wall portion of the mounting tube portion 21, or may be joined to the trunk portion 16f. Alternatively, the trunk portion 16f may be inserted into the placement opening 5a while being careful not to let the plane spacer 32 fall down. In the example shown in FIG. 5, the mounting position of the mounting member 16 can be adjusted by inserting the planar spacers 32 into the four surfaces of the trunk portion 16f. In addition to this example, the planar spacer 32 may be inserted only on one surface side in the longitudinal direction of the trunk portion 16f, or may be inserted only on one surface side in the width direction of the trunk portion 16f. . Further, the self-supporting spacer 40 shown below is for preventing the planar spacer 32, which is made of a magnetic material or the like, from collapsing when the planar spacer 32 is used as the spacer 31. FIG.

<Structure common to self-supporting spacer 40>
At least one of the spacers 31 may be a self-supporting spacer 40 (including 41-47 and 51-55) that can stand on its own while being inserted into the mounting opening 5a. First, the configuration common to the self-supporting spacers 40 will be described. As shown in FIG. 6 and the like, when the self-supporting spacer 40 is inserted into the mounting opening 5a, it is inserted at a position adjacent to the trunk portion 16f of the mounting member 16, which is the positioning portion 10. As shown in FIG. As shown in FIG. 6B and the like, when the self-supporting spacer 40 and the planar spacer 32 are inserted into the mounting opening 5a, the planar spacer 32 is mounted on the self-supporting spacer 40 in the region corresponding to the space 5b. It is inserted between the inner wall portion of the placement opening 5a.

The self-supporting spacer 40 has a bottom portion 41b and the like (including 41b to 47b and 51b to 55b) formed in the plane direction at the lower end in the vertical direction when inserted into the mounting opening 5a. Standing portions 41a and the like (41a to 47a, 51a to 55a) connected to the bottom portion 41b and the like and formed at a predetermined height 41h and the like (including 41h to 47h and 51h to 55h) toward the upper side in the vertical direction. including). By connecting the outermost portions of the bottom portion 41b and the like in the plane direction, predetermined plane regions 41e and the like (including 41e to 47e and 51e to 55e) are formed in the plane direction. The direction along the vertical direction is not limited to the vertical direction, and may be inclined at a predetermined angle with respect to the vertical direction. The height 41h, etc. of the standing portion 41a, etc. is equal to or less than the length between the upper surface of the eaves portion 21m of the mounting tube portion 21 and the upper surface of the spacer stopper 23, as shown in FIG.

<Effects of Configuration Common to Self-supporting Spacers 40>
As described above, the self-supporting spacer 40 can stably stand on its own because the planar region 41e and the like are formed in the bottom portion 41b and the like. By inserting the self-supporting spacer 40 into the area corresponding to the gap 5b of the mounting opening 5a, it is possible to prevent other spacers 31 inserted into the same area from collapsing. In particular, as in the example where the positioning part 10 is the mounting member 16, it is effective when the positioning part 10 and the mounting opening 5a are separate members. The procedure for inserting the spacer 31 is to first insert the self-supporting spacer 40 into the area corresponding to the gap 5b of the mounting opening 5a, and then insert another planar spacer 32 into the same area. Alternatively, the procedure for inserting the self-supporting spacer 40 and the flat spacer 32 may be reversed, or they may be inserted at the same time. Therefore, the mounting member 16, which is the positioning portion 10, prevents the spacers 31 including the self-supporting spacers 40 from falling, and can be inserted with the gaps 5b filled.

<Two configuration examples of the self-supporting spacer 40 and their effects>
Next, a specific configuration and effects of the self-supporting spacer 40 will be described. The self-supporting spacer 40 can be broadly classified into two types in terms of structure. A first configuration example is, as shown in FIGS. 6 to 10, a first self-supporting spacer 41 and the like (including 41 to 47). The first self-supporting spacers 41 and the like are first surface portions in which the standing portions 41a and the like (including 41a to 47a) are formed by planar portions extending in the vertical direction, and the bottom portions 41b and the like (including 41b to 47b). is the second surface portion formed by the planar portion in the planar direction. The first self-supporting spacer 41 and the like are made of metal, resin, wood or other plate materials, net-like members such as wire mesh, or other members having flat surfaces, and may also be elastic members such as leaf springs. For example, when the first self-supporting spacer 41 or the like is formed of an elastic member such as a leaf spring, the standing portion 41a or the like forms a predetermined angle (for example, an acute angle) with respect to the vertical direction, and the upper end portion extends outward in the plane direction. You can tilt. In this case, by first inserting the planar spacer 32 into the mounting opening 5a and then inserting the self-supporting spacer 40, the planar spacer 32 is further prevented from collapsing.

The first self-supporting spacer 41 and the like described above have the following effects. The first self-supporting spacer 41 and the like have the standing portions 41a and the like formed by the first surface portion, and the bottom portions 41b and the like formed by the second surface portion. The first self-supporting spacer 41 or the like can support the other planar spacer 32 or the like within a certain range by the standing portion 41a or the like. Therefore, by inserting the first self-supporting spacer 41 or the like into the area corresponding to the space 5b of the mounting opening 5a, it is possible to prevent the flat spacer 32 or the like from falling down when or after the other flat spacer 32 or the like is inserted.

Next, a second configuration example of the self-supporting spacer 40 is the second self-supporting spacer 51 and the like (including 51 to 55) shown in FIGS. 12 to 14. FIG. The second self-supporting spacer 51 and the like are formed of linear or rod-shaped members, and the bottom portions 51b and the like (including 51b to 55b) are formed by extending continuously in the planar direction, or are formed by extending continuously in the planar direction. It is formed by arranging a portion extending in parallel and a portion of the linear or rod-like member on the same plane. The standing portions 51a and the like are continuous with the bottom portion 51b and the like, are bent upward in the vertical direction, and are formed to a predetermined height 51h and the like (including 51h to 55h). The material of the second self-supporting spacer 51 and the like may be a wire, a wire rod, a round bar member, a square bar member, or an elastic member such as a wire spring. For example, when the second self-supporting spacer 51 or the like is formed of an elastic member such as a wire spring, the standing portion 51a or the like forms a predetermined angle (for example, an acute angle) with respect to the vertical direction, and the upper end portion extends outward in the plane direction. You can tilt. This provides the same effect as when the first self-supporting spacer 41 and the like are made of leaf springs.

Note that the second self-supporting spacer 51 and the like are not limited to the example described later, and may have one standing portion 51a or the like, or may have three or more. In the second self-supporting spacer 51 to the second self-supporting spacer 55 described below, the number of standing portions 52a and the like is not limited to the number shown in the example without departing from the gist of the invention. Also, the height 51h and the like of the erected portion 51a and the like may differ individually.

The second self-supporting spacer 51 and the like described above have the following effects. Since the second self-supporting spacer 51 and the like have the bottom portion 51b and the like and the standing portions 51a and the like formed of linear or rod-like members, the self-supporting spacer 40 can be lightweight and have a flexible shape. Therefore, by inserting the second self-supporting spacer 51 or the like into the area corresponding to the space 5b of the mounting opening 5a, it is possible to prevent the second self-supporting spacer 51 or the like from collapsing when or after inserting the other planar spacer 32 or the like.

<Each form of the self-supporting spacer 40 and its effect>
Next, each form of the self-supporting spacer 40 will be described. The example described below shows an example in which the self-supporting spacer 40 and the planar spacer 32 are combined to adjust the position of the positioning portion 10 with respect to the mounting opening 5a. In any example, the position of the positioning portion 10 may be adjusted only by the self-supporting spacer 40, or the flat spacer 32 may be inserted in a position other than the positions shown in the examples below. Alternatively, in the example shown below, the inserted planar spacer 32 may be omitted.

The first surface portion and the second surface portion each have a predetermined surface area. The standing portion 41a has a height 41h. The first self-supporting spacer 41 is inserted adjacent to the trunk portion 16f of the mounting member 16 forming the positioning portion 10 with the standing portion 41a in the space 5b. As shown in FIG. 6(b), the upright portion 41a supports the planar spacer 32 inserted into the region corresponding to the space 5b to prevent it from falling down. In the example shown in FIG. 6B, the length in the width direction of the standing portion 41a is substantially equal to the width direction dimension of 5 m of the placement opening 5a and the width direction dimension of 16 m of the trunk portion 16f of the mounting member 16. , may be even shorter. In other first self-supporting spacers 42 and the like, which will be described later, the length in the width direction and the length in the longitudinal direction of the upright portions 42a and the like are not limited to the examples shown in the drawings, respectively, and are within the range that can be inserted into the gap 5b. can be changed with

The standing portions 51a are bent upward from the respective bottom portions 51b, and the respective upper end portions are connected along the width direction. A planar region 51e is formed in the planar direction by connecting the respective ends of the bottom portion 51b. The standing portion 51a has a height 51h.

The second self-supporting spacer 52, which is the example shown in FIG. 11(c), has two standing portions 52a arranged substantially parallel to each other at a predetermined interval in the width direction. The bottom portion 52b is bent in the plane direction from each standing portion 52a, extends in the longitudinal direction, and is further connected in the width direction. A planar region 52e is formed in the planar direction by connecting the portion surrounded on three sides and the end portion of the bottom portion 52b. The standing portions 51a and 52a are formed on the front side in the longitudinal direction with respect to the positioning portion 10, but may be on the rear side or on the right side or left side in the width direction. The standing portion 52a has a predetermined height 52h. Note that the heights 52h of the two standing portions 52a may be different. The same applies to other second self-supporting spacers 53 and the like, which will be described later.

In the example shown in FIG. 12(a), the vertical portions 53a face each other in the longitudinal direction. The standing portions 53a have a height 53h, and are formed two each on the front side and the rear side in the longitudinal direction, and the upper ends thereof are connected along the width direction. The bottom portion 53b is formed by connecting the right lower end portion of the standing portion 53a in the width direction along the longitudinal direction. Further, a bottom portion 53b is formed by the lower end portion of the standing portion 53a on the left side in the width direction. The bottom portion 53b is on the same plane in the plane direction, and a predetermined plane area 53e is formed. In the example shown in FIG. 12B, the planar spacer 32 is inserted into each of the front side and rear side in the longitudinal direction with respect to the second self-supporting spacer 53, so that the position of the positioning portion 10 can be adjusted.

In the self-supporting spacer 40 (46, 47, 55) of the fourth embodiment, the standing portions 46a, etc. (including 46a, 46d, 47a, 47d, 55a) They are formed to face each other on both sides. The positioning portion 10 is inserted into a space surrounded by the upright portions 46a and the like.

The configuration of the first self-supporting spacer 46 (47) of the fourth embodiment will be described with reference to FIG. In the first self-supporting spacer 46 of the example shown in FIGS. 9A and 9B, the bottom portion 46b is constituted by the second surface portion, and the four sides of the bottom portion 46b are arranged on the upper side so as to face each other in the width direction and the longitudinal direction. A first surface portion, which is the standing portion 46a, and a first surface portion, which is the standing portion 46d, are formed at , and have a height of 46h. The first self-supporting spacer 46 is formed in a so-called box shape.

The example shown in FIGS. 9A and 9B is based on the assumption that a flat plate such as an iron plate is bent to form the erected portions 46a and 46d. For this reason, the corners are in a separated state, but can be made to have a shape in which the corners are connected by other working directions such as adhesion, welding, deep drawing by pressing, and resin molding. In the example shown in FIGS. 9A and 9B, the planar spacer 32 is inserted into the region corresponding to the four-direction gap 5b in the width direction and the longitudinal direction with respect to the first self-supporting spacer 46, thereby positioning the positioning portion 10. position is adjustable.

When the first self-supporting spacer 47 is formed by bending an iron plate or the like, one of the four corners is notched. The bottom portion 47b is formed by lower end portions of the standing portion 47a and the standing portion 47d that are continuous in the planar direction. Unlike the first self-supporting spacer 46, there is no portion corresponding to the second surface portion, which is the bottom portion 46b, and a planar region 47e in the planar direction surrounded by the bottom portion 47b is formed.

Next, the configuration of the second self-supporting spacer 55 of the fourth embodiment will be described with reference to FIG. 13 . The second self-supporting spacer 55 has a standing portion 55a so as to surround the outer periphery of the positioning portion 10 (the width direction surface 16p and the longitudinal direction surface 16q in the case of the mounting member 16). In the example shown in FIG. 13, two standing portions 55a are formed on each side surface of the positioning portion 10 in the width direction and the longitudinal direction (in the case of the mounting member 16, the width direction surface 16p and the longitudinal direction surface 16q). . The upper end portions of the standing portions 55a are formed so that the upper end portions aligned in the width direction and the longitudinal direction are connected in the plane direction. The lower ends of the standing portions 55a are connected in the plane direction at positions close to the corners to form bottom portions 55b. Connecting the bottom portions 55b forms a planar region 55e in the planar direction. As shown in FIG. 13(b), the planar spacer 32 is inserted in four directions, that is, the front side and the rear side in the longitudinal direction and the right side and the left side in the width direction, in the region corresponding to the space 5b, so that the positioning portion 10 position is adjustable.

<Effect of Movable Mounting Unit 9>
The movable mounting portion 9 described above solves the following problems and produces effects. When a plurality of types of loads 80 are to be loaded, or a plurality of times, and the loading positions of the loads 80 change significantly each time the loads 80 are loaded, it is necessary to change the position of the mounting section 5 . On the other hand, in the loading trailer 1 , at least one of the loading units 5 that determine the position where the load 80 is loaded is the movable loading unit 9 . As shown in FIG. 16 and the like, the load 80 and the movable portion 15 of the movable mounting portion 9 can move in at least one of the longitudinal direction and the width direction with respect to the base 2 and the state in which the movement is restricted. It is selectable. Therefore, the movable placement section 9 can move the movable section 15 according to the size of the load 80 and further restrict the movement of the movable section 15 . When the loading position of the load 80 changes greatly each time the load is loaded, the movable loading section 9 can adjust the position of the loading section 5, so that the loading is possible.

Further, as shown in FIG. 16 and the like, the movable portion 15 can be moved by rotating the male screw member 17d, so that the amount of movement can be adjusted steplessly. Further, when the movable portion 15 is moved, the movement of the movable portion 15 with respect to the guide portion 17 is restricted by the fastening member 17c, so that the movable portion 15 can be prevented from moving after the movement.

<Structure when the movable mounting portion 9 is adjustable in the longitudinal direction>
Next, a configuration in which the movable mounting portion 9 can adjust the position of the mounting portion 5 in the longitudinal direction will be described by taking the B portion in FIG. 1 as an example. Description will be made with reference to FIGS. 16 to 19. FIG. The guide portion 17 is the longitudinal guide portion 7 formed in the longitudinal direction, and the movable portion 15 is guided by the longitudinal guide portion 7 and is movable in the longitudinal direction. The movement adjusting section 14 is a first movement adjusting section 14a, which adjusts the amount of movement of the movable section 15 and adjusts the movement between the movable section 15 and the longitudinal guide section 7 after the movable section 15 has moved. regulate.

As shown in FIG. 18, the longitudinal guide portion 7 is formed by two first rail-shaped members 7a having a U-shaped cross section. The longitudinal guides 7 are fixed to widthwise frames 22 formed at regular intervals in the longitudinal direction. Note that the longitudinal direction guide portion 7 does not necessarily need to be formed parallel to the longitudinal direction, and may be formed in a direction along the longitudinal direction. The longitudinal direction guide portion 7 and the movable portion 15 that constitute the movable mounting portion 9 can be made of metal such as steel, wood, resin, or other materials. As shown in FIGS. 16 and 17, the movable portion 15 is sandwiched between the two first rail-shaped members 7a in the width direction and is guided to move in the longitudinal direction.

In the longitudinal direction, the movable portion 15 can move freely within a predetermined range by moving relative to the longitudinal guide portion 7 by the first movement adjusting portion 14a. Furthermore, the movable portion 15 can select a state in which the movement between the movable portion 15 and the longitudinal guide portion 7 is restricted by the first movement adjusting portion 14a. Therefore, the movable part 15 can select between a state in which it can move relative to the base 2 and a state in which movement is restricted.

<Structure of first movement adjustment unit 14a>
As shown in FIGS. 16 and 17, the first movement adjustment section 14a has the following elements. The movable portion 15 includes a movable mounting tube portion 25, a female screw portion 15c, and a first fastening member 7c. The female screw portion 15c is formed by two nuts that sandwich the female screw plate 15b. In this case, the male screw member 7d corresponds to the male screw member 17d, which is screwed into the female screw portion 15c and extends in the direction in which the movable portion 15 moves. The male screw member 7d has a male screw formed over the entire length in the longitudinal direction. The longitudinal guide portion 7 through which the movable portion 15 is guided is provided with a first guide portion opening 7b that allows the movable portion 15 to move. The first fastening member 7c corresponds to the fastening member 17c, and the longitudinal direction guide portion 7, through which the movable portion 15 is guided, and the movable portion 15 are fastened, and movement of the movable portion 15 is restricted. The first guide opening 7b corresponds to the guide opening 17b.

As shown in FIGS. 16 and 17, for example, the male screw members 7d are passed through the width direction frame 22 at regular intervals in the longitudinal direction, and the other is passed through the male screw support plate 7m in the longitudinal guide portion 7. and sandwiched from the outside in the longitudinal direction by nuts 7e, which are double nuts. The nut 7e is tightened with a gap so as to be rotatable with respect to the width direction frame 22 and the male screw support plate 7m. Therefore, the nut 7 e is always rotatable with respect to the width direction frame 22 . The male threaded member 7d includes a standard screw (JIS, ISO), a ball screw, and a special screw, and the female threaded portion 15c includes a nut shape corresponding to the form of the male threaded member 7d. Both ends of the male screw member 7d may be passed through the base 2 such as the width direction frame 22 or the like.

As shown in FIG. 18, the first fastening member 7c consists of a bolt 7g and a nut 7h. The bolt 7g has a male thread formed at its tip portion, is passed through the movable mounting tube portion 25, and is fastened with a nut 7h. As in FIG. 16, the first fastening members 7c are provided at four positions in the longitudinal direction and the vertical direction.

The movable mounting tube portion 25 has a configuration in which the first fastening member 7c can be attached to the mounting tube portion 21 already described. Specifically, as shown in FIG. 19 and the like, bolt plate portions 25a having holes through which bolts 7g are passed are formed at four locations across the movable opening 15a. The movable mounting tube portion 25 is formed with a canopy portion 25m in the same manner as the mounting tube portion 21, and is placed on the upper surface of the first rail-shaped member 7a of the longitudinal guide portion 7 as shown in FIG.

As shown in FIGS. 18 and 19, the gap 5b is formed only in the width direction and not in the longitudinal direction. This is because the position of the placement section 5 in the longitudinal direction is adjusted by the movable placement section 9 . When the placement position in the longitudinal direction varies greatly depending on the type of the load 80, the placement portion 5 in the longitudinal direction is adjusted by the movable placement portion 9, and the placement position in the width direction, where the difference in placement position is small, is adjusted by the spacer 31. This configuration is suitable for fine adjustment.

<Description of the adjustment method by the first movement adjustment unit 14a>
Next, with reference to FIGS. 16 to 19, an adjustment method by the first movement adjustment section 14a will be described. The movable portion 15 is moved by rotating the male screw member 7d, and when the movable portion 15 is moved, a portion of the first fastening member 7c is inserted into the first guide portion opening 7b. Move with 15. When the movable portion 15 moves to a predetermined position, the movable portion 15 and the longitudinal guide portion 7 in which the movable portion 15 is guided are fastened by the first fastening member 7c to restrict relative movement. Since the amount of movement of the movable portion 15 is reduced with respect to the amount of rotation of the male screw member 7d, the amount of movement can be finely adjusted.

When moving the movable portion 15 in the longitudinal direction, the nut 7h of the first fastening member 7c is loosened and the bolt 7g is moved along the first guide opening 7b. The range in which the first guide opening 7b is formed is the range in which the movable section 15 can move in the longitudinal direction. After moving the movable portion 15 to a predetermined position in accordance with the load 80, the bolt 7g and the nut 7h of the first fastening member 7c are respectively fastened. Through this series of operations, the movable portion 15 can be fixed at a predetermined position.

<Effects of Configuration in which Movable Mounting Unit 9 is Adjustable in Longitudinal Direction>
Moreover, in the case where the movable mounting portion 9 is configured to be adjustable in the longitudinal direction, the following problems are solved and the effects are exhibited. When a plurality of types of loads 80 are loaded or a plurality of loads are loaded, if the loading position in the longitudinal direction of the loads 80 changes significantly each time the loads 80 are loaded, it becomes necessary to change the position of the placement section 5 . On the other hand, as shown in FIGS. 16 to 19, the load 80 and the movable portion 15 of the movable mounting portion 9 can be moved in the longitudinal direction with respect to the base 2 and the movement thereof is restricted. can be selected. Therefore, the movable placement section 9 can move the movable section 15 according to the size of the load 80 and further restrict the movement of the movable section 15 . When the loading position in the longitudinal direction of the load 80 changes greatly each time the load is loaded, the movable placement section 9 can adjust the position of the placement section 5, so that the load can be carried out.

Further, as shown in FIG. 18, since the space 5b is formed only in the width direction, the position of the mounting portion 5 is adjusted by moving the movable portion 15 in the longitudinal direction and the spacer 31 in the width direction. The position can be adjusted by In this case, the longitudinal direction can be adjusted by the movable mounting portion 9, and the width direction can be finely adjusted by the spacers 31. FIG.

<Structure when the movable mounting portion 9 is adjustable in the width direction>
Next, referring to FIGS. 20 and 21, a configuration in which the movable mounting section 9 can adjust the position of the mounting section 5 in the width direction will be described by taking the C section in FIG. 1 as an example. Elements having the same function as the configuration for adjusting the position of the placing section 5 in the longitudinal direction are denoted by the same reference numerals. In this case, the guide portion 17 is the width direction guide portion 8 formed in the width direction, and the movable portion 15 is guided by the width direction guide portion 8 and is movable in the width direction. The movement adjusting section 14 is a second movement adjusting section 14b, which adjusts the amount of movement of the movable section 15 and adjusts the movement between the movable section 15 and the width direction guide section 8 after the movable section 15 has moved. regulate. In addition, the movable part 15 has the same structure as the movable mounting part 9 that is adjustable in the longitudinal direction, which has already been described with reference to FIGS. 18 and 19 .

<Structure of Second Movement Adjusting Unit 14b>
Next, with reference to FIGS. 20 and 21, the configuration and action of the second movement adjusting section 14b will be described. The configuration is the same as that of the first movement adjustment section 14a. The width direction guide portion 8 is formed by two second rail-shaped members 8a having a U-shaped cross section. The width direction guides 8 are fixed to longitudinal frames 24 formed at regular intervals in the width direction. The second movement adjustment portion 14b corresponds to a configuration obtained by rotating the first movement adjustment portion 14a by 90° in the plane direction.

As shown in FIGS. 20 and 21, the movable portion 15 is sandwiched between the two second rail-shaped members 8a in the longitudinal direction and guided to move in the width direction. Note that the width direction guide portion 8 does not necessarily need to be formed parallel to the width direction, and may be formed in a direction along the width direction. As with the longitudinal direction guide portion 7, the width direction guide portion 8 constituting the movable mounting portion 9 can also be made of metal such as steel, wood, resin, or other materials.

In the width direction, the movable portion 15 can move freely within a predetermined range by moving relative to the width direction guide portion 8 by the second movement adjusting portion 14b. Furthermore, the second movement adjusting section 14b allows the movable section 15 to select between a state in which it can move relative to the base 2 and a state in which movement is restricted. The configurations of the movable portion 15 and the fixing device 6 are the same as those shown in FIGS. 18 and 19. FIG.

Next, as shown in FIGS. 20 and 21, in the movable mounting section 9, the second movement adjusting section 14b has the following elements. Elements having the same functions as those of the first movement adjusting section 14a are denoted by the same reference numerals. A female threaded portion 15c formed in the movable portion 15 and a male threaded member 8d that is screwed into the female threaded portion 15c and extends in the direction in which the movable portion 15 moves is provided. The width direction guide portion 8 through which the movable portion 15 is guided is provided with a second guide portion opening portion 8b that allows the movable portion 15 to move. The fastening member 17c corresponds to the second fastening member 8c, and the width direction guide portion 8 through which the movable portion 15 is guided is fastened to the movable portion 15, so that the movement of the movable portion 15 is restricted. The male screw member 8d corresponds to the male screw member 17d, and the guide opening 17b corresponds to the second guide opening 8b.

The movable portion 15 moves by rotating the male screw member 8d. When the movable part 15 moves, part of the second fastening member 8c moves together with the movable part 15 while being inserted into the second guide opening 8b. When the movable portion 15 moves to a predetermined position, the movable portion 15 and the width direction guide portion 8 to which the movable portion 15 is guided are fastened by the second fastening member 8c to restrict relative movement. A more specific adjustment method for the movable portion 15 is the same as that for adjusting the position in the longitudinal direction. As shown in FIGS. 20 and 21, one of the male screw members 8d is passed through and supported by the longitudinal frame 24, and the other is passed through and supported by a male screw support plate 8m formed in the width direction guide portion 8. and is sandwiched from the outside in the width direction by a nut 8e which is a double nut.

The configuration of the fixing device 6 shown in FIGS. 18 and 19 is the same even when the movable mounting section 9 is movable in the width direction. In the examples shown in FIGS. 18 and 19, the gap 5b is formed only in the width direction. is not formed. This is because the position of the placement section 5 in the width direction is adjusted by the movable placement section 9 . When the placement position in the width direction varies greatly depending on the type of the load 80, the placement portion 5 in the width direction is adjusted by the movable placement portion 9, and the placement position in the longitudinal direction where there is little difference in placement position is adjusted by the spacer 31. This configuration is suitable for fine adjustment.

<Effects when the movable mounting portion 9 is adjustable in the width direction>
In the case of the configuration in which the movable mounting portion 9 is adjustable in the width direction as described above, the following problems can be solved and the following effects can be obtained. When a plurality of types of loads 80 are loaded or multiple times, and when the loading position in the width direction of the loads 80 changes greatly each time the loads 80 are loaded, the placement section 5 needs to be adjusted. On the other hand, as shown in FIGS. 20 and 21, the load 80 and the movable portion 15 of the movable mounting portion 9 can move in the width direction with respect to the base 2 and the state in which the movement is restricted. It is selectable. Therefore, the movable placement section 9 can move the movable section 15 according to the size of the load 80 and further restrict the movement of the movable section 15 . In the case where the loading position in the width direction of the load 80 changes greatly each time the load is loaded, the movable placement section 9 can adjust the position of the placement section 5, so that it is possible to load the load.

In addition, since the space 5b is formed only in the longitudinal direction, the position of the mounting portion 5 can be adjusted by moving the movable portion 15 in the width direction and adjusted by the spacer 31 in the longitudinal direction. can. In this case, the width direction can be adjusted by the movable mounting portion 9 and the longitudinal direction can be finely adjusted by the spacer 31 .

It is a range of dimensions that is equal to or less than the second major axis 82b and that creates a predetermined gap with respect to the second major axis 82b.

A bolt is used for the screw shaft portion 12 and is formed integrally with the screw head portion 12a. In addition, the screw head 12a and the screw shaft 12 may be separate bodies and synchronized with each other in the rotational direction and the vertical direction.

As shown in the partial cross-sectional view of FIG. 3 and the like, the inside of the head portion 11 is formed with a recess corresponding to the shape of the screw head portion 12a. The head 11 and the screw shaft tube 26 are fixed to each other with the screw head 12 a inserted inside the head 11 . When the flange of the screw head 12a comes into contact with the upper end of the screw shaft tube 26 and a force directed downward in the vertical direction is generated in the screw head 12a, the head 11 is similarly directed downward. A force is generated to engage the load bearing surface 81 of the load 80 .

As shown in FIG. 4 and the like, the screw shaft portion 12 is provided with an adjusting nut 13a below the bottom plate 21p so as to sandwich the mounting portion 5 in the vertical direction. The adjusting nut 13a has a function of pressing the load support surface 81 of the fixing device 6 toward the base 2 side at the same time as the mounting portion 5 in cooperation with the screw head 12a.

The adjusting nut 13a is rotated by the adjusting mechanism portion 13b to adjust its vertical position. The adjusting mechanism part 13b has a ratchet mechanism capable of switching the transmission direction, and when it rotates in one direction, it transmits rotation to the adjusting nut 13a, and when it rotates in the other direction, it rotates idle. The adjustment mechanism part 13b selects either the direction of tightening the adjustment nut 13a (the direction of tightening the mounting part 5) or the direction of loosening the adjustment nut 13a (the direction of loosening the mounting part 5) using a changeover switch. to use. When the adjusting nut 13a rotates in the tightening direction, it cooperates with the screw head 12a to press the load support surface 81 toward the base 2 side.

The configuration of the fixing device 6 described above has been described for the case where the mounting section 5 is fixed to the base 2 as shown in FIGS. 2 to 4 . Next, with reference to FIGS. 16 to 21, the configuration of the fixing device 6 unique to the movable mounting portion 9 will be described. The fixing device 6 has the same configuration as that of FIGS. 3 and 4 already described, and elements having similar functions are denoted by the same reference numerals or may be omitted to omit the description thereof.

3 and 4, the fixing device 6 in the movable mounting portion 9 is provided with a movable mounting tube portion 25 instead of the mounting tube portion 21, as shown in FIGS. A screw shaft tube 36 is provided instead of the screw shaft tube 26 . The screw shaft portion 12 is inserted into the shaft hole 36 a of the screw shaft tube 36 . Also, as will be described later, the mounting position of the rotary lever 30 is different.

As already explained, in the case of the example shown in FIGS. 3 and 4 , the mounting tube portion 21 is fixed to the width direction frame 22 or other portion of the base 2 . Therefore, when the head 11 of the fixing device 6 is engaged with the load support surface 81 of the load 80 , the load 80 is restricted from moving vertically with respect to the base 2 . On the other hand, when the mounting section 5 is the movable mounting section 9 as in the examples shown in FIGS. 16 to 19, the following points are different. The movable mounting tube portion 25 is not fixed to the base 2, but its movement in the vertical direction is restricted with respect to the longitudinal guide portion 7 by the first fastening member 7c. 3 and 4, when the head 11 of the fixing device 6 engages the load support surface 81 of the load 80, the load 80 is placed against the base 2. movement in the vertical direction is restricted.

Further, as shown in FIGS. 18 and 19, the rotary lever 30 is attached to the lower portion of the screw shaft tube 36 in the vertical direction. This is because if it is attached to the middle portion in the vertical direction of the screw shaft tube 26 as in the example shown in FIGS. A male screw 30 b is formed on the rotary lever 30 and is screwed into a female screw portion 36 b of a screw shaft tube 36 to be attached. A bottom plate 25p is fixed to the lower end portion of the movable mounting tube portion 25, and the adjustment portion 13 is configured below the bottom plate 25p. The configuration of the adjustment unit 13 is the same as the examples shown in FIGS.

<Effect of fixing device 6>
The configuration of the fixing device 6 described above has the following effects. A conventional loaded trailer (loaded trailer described in Patent Document 1) is supported by a cargo bed via four anchor posts, which are fixing devices for supporting a load. On the other hand, it is not possible to restrict the vertical movement of the load. That is, when the load is transported while being loaded on the truck, there is a possibility that the load may move vertically with respect to the loading platform due to the vibration of the truck. There is a problem that the load may be damaged by vibrating vertically with respect to the loading platform.

In contrast, the fixing device 6 described above solves these problems. By rotating the rotary lever 20 (30), the head 11 is engaged with the load support surface 81 through the rotation of the mounting tube portion 21, and the screw head 12a rotates the adjustment nut 13a. is adjusted by moving up and down. When the head 11 engages with the load support surface 81, the load 80 and the mounting section 5 are restricted from moving relative to each other in the vertical direction, so the load 80 should be fixed to the mounting section 5. can be done.

Also, when the head 11 is in a state in which it can be inserted into and removed from the support surface opening 82 of the load 80 , the load 80 can be placed on or removed from the placement section 5 . Therefore, the fixing device 6 can be selected between a state in which the load 80 can be placed on the placement section 5 and a state in which the load 80 is fixed on the placement section 5 . When a force is generated to move the screw head 12 a downward in the vertical direction, a force is generated in a direction in which the load supporting surface 81 is pressed against the base 2 via the head 11 . Therefore, since there is no gap between the head 11 and the load support surface 81, it is possible to prevent the load support surface 81 from moving in the vertical direction.
