Description

  The present invention relates to a wing vehicle and a van type vehicle including a movable partition wall that partitions a luggage compartment forward and backward at an arbitrary position.

  A wing car that pivots vertically on the left and right sides of the center beam to form a part of the roof and the upper part of the side wall so as to be pivotable in the vertical direction, and is equipped with a refrigeration unit or refrigeration unit on the front wall side inside the cargo compartment. Is widely used. The wing wheel has an advantage that when the wing is opened upward and the lower portion of the side wall is opened downward, the side surface of the luggage compartment is greatly opened, and the cargo can be easily loaded and unloaded.

  On the other hand, van-type cars with box-type luggage compartments equipped with refrigeration equipment or refrigeration equipment and doors that open and close to the left and right are also widely used when the amount of cargo is small because of the small turning. Has been.

  By the way, for example, products that are transported in a frozen or refrigerated state, such as frozen meat and seafood, and products that are transported at room temperature, such as vegetables and fruits, are transported simultaneously in the same van type car. For this purpose, partition sheets and panels that divide the luggage compartment of a van-type vehicle back and forth are used.

  FIG. 11 shows the configuration of a conventional partition sheet 101 used in a van type car equipped with a freezing / refrigeration apparatus (Patent Document 1).

  The partition sheet 101 of Patent Document 1 is composed of an upper sheet 102 and a lower sheet 103 which are divided into two parts, as shown in (a), and hook and loop fasteners 104a and 104b are attached to and detached from the upper edge of the upper sheet 102. Accordingly, a bent portion 104 is provided that can be suspended from a metal support bar that is spanned between the upper portions of the left and right side surfaces of the cargo compartment. Reference numeral 105 denotes a gripping member that is inserted and gripped by the support rod.

  When the partition sheet 101 is used to partition the luggage compartment 106a of the van type car 106 forward and backward, as shown in FIG. 11B, the holding member 105 is held by the support rod 107, and the bent portion 104 is further moved. The partition sheet 101 is suspended and supported on the support rod 107 by bending and bonding the surface fasteners 104a and 104b. Further, when not in use, the upper sheet 102 and the lower sheet 103 are separated, and the upper sheet 102 is fixed with the other end locked near the ceiling surface of the cargo compartment 106a as shown in FIG. 103 can be folded and stored in a gap between the upper sheet 102 and the ceiling surface of the luggage compartment 106a.

  Conventionally, a fitting-type partition panel that is approximately the same size as the frame inside the luggage compartment of a van type car has also been used. In this type of partition panel, first, a frozen or refrigerated product is loaded in the front of the luggage compartment, then the partition panel is fitted, and finally a product to be carried at room temperature is loaded.

  In addition, as shown in FIG. 12, rails 203a and 203b are provided in the front-rear direction on the left and right side walls of the luggage compartment 202 of the van type car 201, respectively, and the front-rear direction is provided along the rail between the rails 203a and 203b. A metal support rod 204 that can be moved is bridged, and engaging members 205 are provided at two locations of the support rod 204 to suspend a partition panel (not shown). . In this type of van type vehicle, first, the panel is flipped up outward, and after the frozen or refrigerated goods are loaded in front of the luggage compartment, the panel is returned to the state of being suspended from the support bar 204 and the required The product is moved to the position, and finally the goods to be carried at room temperature are loaded.

  However, the partition sheet 101 of Patent Document 1 and the flip-up type partition panel as shown in FIG. 12 require support rods 107 and 204 that span the side walls of the cargo compartment. For this reason, the space in the vertical direction of the cargo space is reduced by the amount of installation of the support bars 107 and 204. Therefore, the operator needs to be careful not to hit his / her head or product against the support bars 107 and 204. There was a drawback that it was difficult to do the wholesale work. In addition, when loading and unloading products, the upper sheet 102 and the lower sheet 103 are separated and stored near the ceiling surface of the luggage compartment, or the panel is flipped outward. Since it is time-consuming, there was a problem in terms of work efficiency.

  In addition, in the case of a fitting type partition panel, there is a problem that when the panel is fitted to the front of the cargo compartment, the panel cannot be moved smoothly and the work takes time. In addition, there is no place for partition panels while goods to be carried in a frozen or refrigerated state are loaded in front of the cargo compartment, and there is no choice but to place them temporarily outside the vehicle.

  Further, any of the conventional partition sheet 101, the flip-up type panel, and the fitting type panel are not suitable for attachment to a wing vehicle. This is because the wing wheel is pivotally mounted on both the left and right sides of the center beam so that the wing composed of the upper portion of the side wall and the ceiling surface is pivotally mounted so that the wing opens and closes. This is because the structure is not suitable for constructing such a member. In addition, the fitting-type panel is also difficult to apply to a wing car because the panel falls when the wing is opened.

JP-A-9-236379

  The problem to be solved by the present invention is that, in the case of a conventional partition sheet or panel, a support bar that spans between the left and right side walls of the cargo compartment is required, so that the space in the vertical direction of the cargo compartment is narrow. The point and the operation | work which latches the lower end of a sheet | seat to the ceiling surface of a cargo compartment, or a panel jumps up outside a vehicle are the points which were the points where the efficiency of unloading work was bad.

The wing car of the present invention is
In order not to narrow the space in the vertical direction of the cargo room and improve the efficiency of unloading work,
A front wall is erected at the front end of the floor of the luggage compartment, and a rear wall or door frame is erected at the rear end, and a center beam is installed between the upper part of the front wall and the upper part of the rear wall or door frame. In a wing car that pivots vertically on the wing that forms part of the roof and the upper part of the side wall on both the left and right sides of the beam,
At least a part of a rail having a traveling groove portion on which a wheel of a suspension vehicle travels is attached to the center beam, and an upper end portion of a partition wall that partitions the luggage compartment forward and backward at an arbitrary position is suspended from the suspension vehicle. The most important feature is that

The van type car of the present invention is
In order not to narrow the space in the vertical direction of the cargo room and improve the efficiency of unloading work,
A box-shaped luggage compartment, and a supporting beam is installed between the upper part of the front wall at the front end of the luggage compartment and the rear wall or the upper part of the door frame at the rear end. At least a part of a rail having a traveling groove portion for traveling is attached, and a van type vehicle in which an upper end portion of a partition wall for partitioning the luggage compartment in front and rear at an arbitrary position is suspended from the suspension vehicle,
The rail includes a linear first moving portion attached along the direction in which the support beam is installed, and a second curved portion attached so that the terminal ends away from either the left or right side wall away from the support beam. The main feature is that it consists of a moving part.

  In the present invention, a rail having a traveling groove portion on which the wheel of the suspension vehicle travels is attached to the center beam or the support beam, and the partition wall is suspended from the suspension vehicle so that it can be moved back and forth. A support rod that spans between the side walls is unnecessary, and the space in the vertical direction of the cargo compartment is not reduced. Moreover, since the partition wall can be smoothly moved along the rail while being suspended, the efficiency of unloading work can be improved.

  In the wing vehicle of the present invention, the rail has a linear first moving portion attached along the center beam erection direction, and a curved shape attached so that the terminal ends away from either the left or right side wall away from the center beam. It is desirable to configure with the second moving part. This is because the partition wall can be stored along the side wall, so that it does not get in the way of the operator when the goods to be transported in the frozen or refrigerated state are loaded from behind.

  In the above case, it is more desirable to provide a guide member for height adjustment in the gap between the second moving part and the ceiling surface of the cargo compartment because the attachment of the second moving part is stable. For the same reason, in the van type vehicle of the present invention, it is desirable to provide a guide member for height adjustment in the gap between the second moving part and the ceiling surface of the luggage compartment.

  In the present invention, even when a movable partition wall is provided to partition the cargo compartment back and forth, the purpose is to reduce the space in the vertical direction of the cargo compartment and improve the efficiency of unloading work. This is realized by attaching at least a part of the rail having the traveling groove part on which the wheel of the suspended vehicle travels to the support beam provided on the beam or van type vehicle and suspending the upper end of the partition wall on the suspended vehicle. .

  DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode for carrying out the present invention together with a new idea of the present invention will be described below with reference to the accompanying drawings.

  The inventor has installed a support beam between the upper part of the front and rear walls or door frame in the case of a wing car, and in the case of a van type car, and the wheel of the suspension car is attached to the support beam. At least a part of the rail having a traveling groove for traveling is attached, and the upper end of the partition wall is hung on a suspension car, so that the partition wall can be used as a rail without providing support rods between the left and right side walls of the cargo compartment. As a result, the present invention was completed.

  Hereinafter, the best mode of the present invention in which a rail is attached to a center beam of a wing vehicle and a partition wall is suspended will be described with reference to FIG.

  In the wing vehicle 1 of the present invention, a front wall 12 is erected at a front end of a floor 11 of a cargo compartment formed on a loading platform, a door frame 13 is erected at a rear end, and an upper portion of the front wall 12 and a door frame are arranged. A center beam 14 is installed between the upper parts of 13 in the front-rear direction, and wings 17 forming a part of the roof 15 and the upper parts 16a of the side walls are pivotally attached to the left and right sides of the center beam 14 so as to be rotatable in the vertical direction. At least a part of the rail 2 having a traveling groove portion on which the wheel of the suspended vehicle travels is attached to the center beam 14, and the upper end portion 3aa of the movable partition wall 3 that partitions the luggage compartment back and forth at an arbitrary position is provided. It is hung on a hanging car. In addition, 13a is a door provided in the door frame 13, and can be opened and closed left and right. In addition, a refrigeration apparatus or a refrigeration apparatus (not shown) is attached to the front wall 12.

  The lower portions of the left and right side walls of the cargo compartment are turned portions 16b, which can be rotated downward with the position of the floor of the cargo compartment as a fulcrum. On the inner side of the turn part 16b, there is provided an engagement part 18 in which the installation position of the partition wall 3 is positioned and concave locking parts for fixing the partition wall 3 are arranged in the front-rear direction. A similar engaging portion 18 is similarly provided on the inner side of the side wall portion 16 a of the wing 17. These engaging portions 18 are engaged with convex portions provided on the side surfaces of the partition wall 3 to fix the partition wall 3 at a required position.

  The wing 17 is pivotally attached to both the left and right sides of the center beam 14 so as to be able to rotate up and down via, for example, a hinge. The gap between the hinges is covered by sealing with waterproof rubber.

  Next, the structure of the rail 2 used for the wing vehicle 1 of this invention is demonstrated using FIG. (A) shows the state seen from the side, and (b) and (c) show the state seen from above.

  As shown in FIGS. 2B and 2C, the rail 2 of the present embodiment includes a linear first moving portion 21 attached along the construction direction of the center beam 14 (the longitudinal direction of the wing car), and the center The curved second moving unit 22 is attached so as to be separated from the beam 14 so that the terminal end reaches one of the left and right side walls. In the example shown in FIG. 1, the curved second moving portion 22 curves in the direction of the right side wall and extends until reaching the side wall.

  Therefore, in the wing vehicle 1 of this embodiment, when loading products such as frozen meat and frozen fish that are first transported in a frozen or refrigerated state, as shown in FIG. Since it can be stored in a position along the right side wall, and it does not get in the way even when loading work is performed from the rear door 3a, it is very convenient.

  Then, as shown in FIG. 2 (b), when the goods to be transported in the frozen state or the refrigerated state are loaded into the section indicated by A in the figure, the partition is made up to a required position according to the amount of the loaded goods. Since the products such as vegetables and fruits which are moved at the wall 3 and then transported at room temperature can be loaded in the section indicated by B, the work efficiency is improved.

  In this embodiment, as shown in FIG. 2A, when the length in the left-right direction of the cargo compartment is set to 1 in a side view, a curved shape is formed at a position approximately 3/4 when viewed from the front wall 12. However, the present invention is not limited to this. The length of the linear first moving portion 21 can be made longer than that of the present embodiment or can be made shorter, and can be appropriately designed as necessary.

  FIGS. 3A and 3B illustrate the configuration of the partition wall 3 used in the wing vehicle 1 of the present invention. FIG. 3A is an overall view, and FIG. 3B is a diagram illustrating the shape of a frame. The frame 3a of the partition wall 3 becomes heavy when pipe-shaped steel is used, and the load on the rail becomes large when the partition wall 3 is suspended, and a considerable force is required to move the partition wall 3. Therefore, as shown in (b), a steel material having a U-shaped cross section was used. As a result, the weight can be reduced as much as possible, and a certain durability can be ensured.

  Reference numeral 3b denotes a heat insulating material fitted into the frame 3a. As the heat insulating material 3b, urethane or sponge material can also be used. However, since a heavy one becomes disadvantageous when the partition wall 3 is suspended, a lightweight foamed polystyrene is used in this embodiment. . This is preferable because the weight can be reduced without losing the heat insulating effect.

  In FIG. 3A, 31 indicates a suspension vehicle that travels in the traveling groove portion of the rail 2, and 34 indicates a grip portion that is used as a handle when an operator moves the partition wall 3 in the cargo compartment. . Moreover, the 1st engagement member 32 and the 2nd engagement member 33 are provided in the upper end part 3aa of the partition wall 3 as a member for making the partition wall 3 and the suspension vehicle 31 latch.

  In addition, the sealing material which consists of rubber | gum etc. is attached to the circumference | surroundings of the side part of the partition wall 3, and the sealing property with the floor of a luggage compartment, a side surface, and a ceiling surface is improved.

  Next, the cross-sectional shape of the rail 2 and the means for suspending the partition wall 3 will be described with reference to FIG. The rail 2 used in the wing vehicle 1 of this embodiment includes a frame portion 24 having a U-shaped cross section and a traveling groove portion 23 that travels in contact with a wheel 31a of a suspension vehicle 31 as shown in FIG. Consists of. The traveling groove portion 23 has a required width that allows the wheels 31 a to travel, and is provided in the horizontal direction one by one from the left and right side lower portions of the frame portion 24 toward the central portion. The suspension vehicle 31 has two wheels 31 a connected by a shaft 31 b, and each wheel 31 a can roll in the mounting direction of the rail 2 along the traveling groove portion 23.

  As described above, in the present invention, at least a part of the rail 2 having the traveling groove 23 on which the wheel 31 a of the suspension vehicle 31 travels is attached to the center beam 14, and the upper end 3 aa of the partition wall 3 is suspended from the suspension vehicle 31. Since the configuration to be provided is employed, for example, the partition wall 3 can be moved very smoothly as compared with a conventional flip-up panel that is moved while being suspended from a support rod.

  The traveling groove 23 may be inclined downward at an inclination angle of 5 degrees or more and 30 degrees or less from the lower left and right side surfaces of the frame portion 24 toward the center. In this case, the two wheels 31a of the suspension vehicle 31 are not provided in parallel, but are provided with an inclination angle of 5 degrees or more and 30 degrees or less with the lower side of the wheels 31a facing outward. In this way, when the suspension vehicle 31 is laterally displaced in the rail 2, it is possible to generate a force that always returns it to the center position, so that the contact between the suspension vehicle 31 and the side surface of the frame portion 24 is prevented. Can be reduced. Therefore, it is possible to prevent as much as possible contact due to the lateral displacement of the suspension vehicle 31 and to further stabilize the movement of the partition wall 3.

  Further, in this embodiment, as shown in FIG. 4 (b), the suspension means for the suspension wheel 31 and the partition wall 3 is formed by bending the central part of a rod-shaped member having a circular cross section into a mountain shape and suspending both ends. While using the 1st engaging member 32 made to attach to the upper end part 3aa of the partition wall 3, it is a plate-shaped which has the shaft hole 33a which penetrates the axis | shaft 31b, and the hole 33b which penetrates the 1st engaging member 32 The second engaging member 33 is used.

  If it does in this way, first, along the shape of the 1st engaging member 32 which bent the center part into the mountain shape, the partition wall 3 can increase the freedom degree of the rotation of the horizontal direction shown by the arrow X. FIG. Further, if the size of the hole 33b provided in the second engagement member 33 is made larger than the shaft diameter of the first engagement member 32, the partition wall 3 also increases the degree of freedom of rotation in the horizontal direction indicated by the arrow Y. it can. Furthermore, since a round bar-shaped member is used for the first engagement member 32, the degree of freedom of rotation in the front-rear direction indicated by the arrow Z can be increased. Therefore, when configured as in the present embodiment, it is possible to follow the three-dimensional movement applied when the partition wall 3 is housed, thereby reducing the load on the suspended vehicle 31 and the rail 2 portion. Therefore, there is an advantage that the durability of the suspension vehicle 31 and the rail 2 can be improved.

  The suspension wheel 31, the first engagement member 32, and the second engagement member 33 are made of stainless steel so as to improve durability from the surface of the material. Further, both end portions of the first engagement member 32 and the upper step portion 3aa of the partition wall 3 are joined by welding, for example.

  FIG. 5 is a view of the state in which the rail 2 is attached to the center beam 14 on the ceiling surface as viewed from below. In the present embodiment, the upper surface of the U-shaped frame portion 24 of the rail 2 is attached to the center beam 14 by performing nut welding 2c at a plurality of locations. As a method of attaching to the center beam 14, bolting may be considered. However, when a through hole is provided in the center beam 14, there is a possibility that a crack may enter from that portion, so that it is attached by nut welding 2 c as in this embodiment. Is preferable.

  FIG. 6 is a diagram illustrating the configuration of the engaging portion 18 provided on the inner side of the turn portion 16 b and the inner side of the side wall portion 16 a of the wing 17. The engaging portion 18 is used for positioning and fixing the partition wall 3, and concave locking portions 18 a and 18 b are arranged in the front-rear direction of the vehicle. In this embodiment, the locking portion 18a is formed in a “+” shape, and the locking portion 18b is formed in a “−” shape. Protrusions that engage with the locking portions 18a and 18b are provided on the side surfaces of the partition wall 3, and the partition walls 3 are brought into the required positions by fitting the protrusions to the locking portions 18a and 18b. Fixed.

  Next, the best mode of the present invention will be described with reference to FIGS. 7 to 8 in which a support beam is installed in the front and rear direction in a luggage compartment of a van type car, a rail is attached to the support beam, and a partition wall is suspended. To do. FIG. 7 shows the configuration of the front portion of the van type vehicle 10, and FIG. 8 shows the configuration of the rear portion.

  The van type vehicle 10 of the present invention includes a box-shaped luggage compartment 50, and a support beam 54 is provided between an upper part of a front wall 52 at the front end of the luggage compartment 50 and an upper part of a rear wall or door frame 53 at the rear end. At least a part of a rail having a traveling groove portion on which a wheel of a suspended vehicle travels is attached to the support beam 54 and the upper end portion of the partition wall 3 that partitions the luggage compartment 50 forward and backward at an arbitrary position is used as a suspended vehicle. It is suspended.

  That is, when the present invention is applied to a wing vehicle, the rail 2 is at least partially attached to the center beam 14 as described above. A support beam 54 is installed between the upper part of the front wall 52 at the front end and the upper part of the rear wall or the door frame 53 at the rear end, and the rail 2 is attached to the support beam 54. For the support beam 54, a steel material having a required width for mounting the rail 2 and having a strength capable of suspending the partition wall 3 is used.

  Here, as shown in FIG. 8, the rail 2 has a linear first moving portion 21 attached along the installation direction of the support beam 54, and a terminal end on either the left or right side wall away from the support beam 54. It is comprised from the curved 2nd moving part 22 attached so that it might reach. The cross-sectional structure of the rail 2, the configuration of the partition wall 3, and the means for suspending the suspension vehicle 31 are not different from those of the wing vehicle 1 described above, and thus the description thereof is omitted.

  As shown in FIG. 8, the partition wall 3 has a thickness equal to or less than the width of the pillar 10 a existing at the rear end of the van type car 10, so that the partition wall 3 is stored at a position in contact with the side wall. When it does, it does not get in the way for the worker.

  FIG. 9 is a diagram illustrating an installation mode of the partition wall 3 in the van type vehicle 10 of the present invention. First, when it is desired to use all of the cargo compartment 50 at room temperature, the partition wall 3 is moved to a position in contact with the front wall (FIG. 9A). In addition, when there are a small amount of goods to be carried in a frozen or refrigerated state and many goods to be carried at room temperature, the partition wall 3 is moved from the front to a position of about 1/4 (FIG. 9B). When there are the same amount of frozen or refrigerated products and normal temperature products, the partition wall 3 is moved to the center position (FIG. 9C). Further, when it is desired to use all of the cargo compartment 50 in a frozen or refrigerated state, the partition wall 3 is moved to a position along the right side wall (FIG. 9D).

  Even if there is no product to be transported at room temperature, if the amount of the product to be transported in a frozen or refrigerated state is small, it is not in the state of (d), but depending on the amount of the product (b) or It is desirable to carry in the state of (c). In this way, the luggage compartment can be made compact according to the amount of goods, so the burden on the refrigeration unit or refrigeration unit is reduced, and consequently the engine load is reduced, leading to savings on gasoline. Because.

  FIG. 10 is a diagram illustrating the configuration of a guide member for height adjustment used in the wing wheel 1 and the van type vehicle 10 of the present invention.

  In the van type vehicle 10 of the present invention, the rail 2 is attached to the support beam 54, but as shown in FIG. 10A, the curved second moving portion 22 is loaded at a position away from the support beam 54. Since attachment to the ceiling surface 55 of the room is necessary, it is desirable to provide the guide member 4 for height adjustment in the gap between the second moving part 22 and the ceiling surface 55 of the cargo room. The height of the guide member 4 is substantially the same as the height of the support beam 54. This stabilizes the mounting of the rail 2.

  The same applies to the wing wheel 1 of the present invention when the rail 2 having the curved second moving portion 22 is used. FIG. 10B is a view of the wing vehicle 1 as viewed from the rear. However, since the wing vehicle 1 needs to be attached to the ceiling surface 15a of the luggage compartment at a position away from the center beam 14, the second moving part 22 and the cargo compartment are shown. It is desirable to provide guide members 4a to 4d for height adjustment in the gaps between the ceiling surfaces 15a. The height of the guide members 4a to 4d may be substantially the same as the height of the center beam 14, and may be finely adjusted according to the shape of the ceiling surface 15a of the luggage compartment. Thereby, the attachment of the rail 2 can be stabilized.

  As is apparent from FIG. 10B, when the rail 2 having the curved second moving portion 22 is used in the wing wheel 1, the steel material of the rail 2 is cut at a position 25 in the middle of the rail 2. When the wing 17 is opened, the first moving unit 21 and the second moving unit 22 need to be separated. When the wing 17 is in a closed state, the first moving unit 21 and the second moving unit 22 are made continuous.

  Finally, a test method and results for verifying the effect of the partition wall 3 of the wing wheel 1 of the present invention will be described. First, the refrigeration unit attached to the front wall 12 of the wing vehicle 1 is operated with the set temperature set to -5 ° C. or -20 ° C., and the partition wall 3 is moved to a substantially central position of the cargo room for one hour. Later, the room temperatures of the freezing space in front of the cargo compartment and the room temperature space behind the cargo compartment were measured. Note that the outside air temperature at this time was 10 ° C.

  The results are as shown in Table 1. First, in the refrigeration space in front of the cargo compartment, room temperature almost the same as the set temperature of the refrigeration apparatus was obtained, and it was confirmed that even if the partition wall 3 was used, the function of the refrigeration apparatus was not deteriorated at all. Further, in the room temperature space behind the cargo room, it was confirmed that the partition wall 3 cuts off cool air from the front space, and a room temperature almost the same as the outside temperature was obtained.

  Therefore, according to the present invention, a single vehicle can have both functions of a freezing / refrigerated vehicle and a normal temperature vehicle, and products that require refrigeration (frozen meat, frozen fish, etc.) that were conventionally carried by two vehicles. ) And room-temperature products (vegetables, fruits, etc.) can be carried by a single vehicle. Moreover, since the frequency | count of driving | running | working of a vehicle can be reduced by carrying with one vehicle, this invention also contributes to reduction of greenhouse gases, such as a carbon dioxide.

  The present invention is not limited to the above example, and it goes without saying that the embodiments may be changed as appropriate within the scope of the technical idea described in each claim.

  For example, in the wing vehicle 1 in the example of FIGS. 1 to 2, the rail 2 has a curved second moving portion 22 that is curved in the direction of the right side wall 16a. Like the wing wheel 1, all of the rails 20 that are all linear from the position of the front wall 12 at the front end to the position of the rear wall or door frame 13 at the end may be attached to the center beam 14.

  Because, in the case of the wing vehicle 1, if the wing 17 and the turn portion 16 b are opened, the side walls are greatly opened, and therefore the partition wall 3 can be moved only in the front-rear direction using the rail 20 that is straight in the entire section. Even with this configuration, it is possible to load and unload luggage from the side.

  On the other hand, in the case of the van type car 10, since it is a box-shaped luggage compartment 50, when the partition wall 3 is movable only in the front-rear direction using the rail 2 that is straight in all sections, , The place which escapes the partition wall 3 will be lost. Therefore, when the present invention is applied to a van type vehicle, it is necessary to use the rail 2 having the curved second moving part curved in the direction of either the left or right side wall.

  Of course, even in a wing vehicle, there are cases where cargo is unloaded from the rear door depending on the amount of cargo and parking conditions. Therefore, considering that point, it can be said that in the present invention, it is more preferable to use the rail 2 having the curved second moving portion even in the wing vehicle.

  Further, in the example of the invention shown in FIG. 1, the door frame 13 exists at the rear end of the floor 11, but a rear wall may be erected at this portion.

  Further, in the example of the invention shown in FIG. 2, the suspension vehicle 31 having two wheels 31a at both ends of the shaft 31b and the single rail 2 having two traveling grooves 23 are used. And the shape of the rail is not limited to this. For example, the suspension vehicle may have one wheel or three or more wheels, and the shape of the rail may be selected accordingly. Moreover, you may attach a rail in parallel with two rails.

  The present invention described above can be applied to wing cars and van type cars in general regardless of the size and shape of the vehicle.
