Description

[Technical Field]

[0001] The present invention relates to a multi-purpose vehicle equipped with a cargo bed. [Background technology]

[0002] As shown in Patent Document 1, there is a vehicle that is equipped with a bed (bed, side walls) and an extension bed (bottom wall, side walls, extender tailgate), and the bed can be extended by the extension bed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] U.S. Patent No. 5,456,511 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described bed extension, the bed is extended by extending the extension bed rearward from the bed, so when the bed is extended, the overall length of the vehicle increases.

[0005] To provide a multipurpose vehicle in which the loading platform can be extended without increasing the overall length of the vehicle. [Means for solving the problem]

[0006] The multi-purpose vehicle according to the present invention comprises: The vehicle is equipped with a boarding section having a front boarding space for driving and a rear boarding space located rearward of the front boarding space, a cargo bed provided rearward of the boarding section, and an extended cargo bed, and the extended cargo bed can be changed in position between an extended cargo bed position in which it extends forward from the cargo bed and enters the rear boarding space, and an extended released position in which it extends rearward from the rear boarding space and overlaps with the front of the cargo bed.

[0007] According to this configuration, the cargo bed is extended by the extension cargo bed that extends forward from the cargo bed and enters the rear passenger space. Because the rear passenger space is utilized in the space where the extension cargo bed is located in the extended cargo bed position, the cargo bed can be extended by the extension cargo bed without increasing the overall length of the vehicle.

[0008] In the present invention, The extended loading platform preferably has a pivot axis aligned along the width direction of the vehicle body, and is pivoted toward the front of the vehicle body around the pivot axis as a pivot fulcrum, causing it to collapse and assume the extended loading platform position, and is pivoted toward the rear of the vehicle body around the pivot axis as a pivot fulcrum, causing it to stand up and assume the released extension position.

[0009] For example, when folding the extended cargo bed under the vehicle body to the extended / unextended position, it takes time and effort to change the position of the extended cargo bed between the extended cargo bed position and the unextended position. Furthermore, the extended cargo bed in the unextended position tends to get dirty. With this configuration, the extended cargo bed changes its position between the extended cargo bed position and the unextended position simply by swinging the extended cargo bed, so changing the position of the extended cargo bed does not require much effort. Furthermore, because the extended cargo bed in the unextended position is upright and less likely to get dirty, it is easy to handle, making it easy to operate and expand or reduce the luggage loading space.

[0010] In the present invention, The loading platform has a bottom plate portion, horizontal frame portions located on both lateral sides of the bottom plate portion, a rear frame portion located at the rear of the bottom plate portion, and a front opening facing forward and outward at the front of the loading platform, and the extended loading platform has an extended bottom plate portion, extended horizontal frame portions located on both lateral sides of the extended bottom plate portion, and an extended front frame portion located at the front of the extended bottom plate portion, and it is preferable that the extended bottom plate portion covers the front opening in the extended released position.

[0011] According to this configuration, when the extended loading platform is in the extended release position, the front opening of the loading platform is covered by the extended bottom plate portion, so when the extended loading platform is in the extended release position and cargo is loaded onto the loading platform, the extended bottom plate portion can be used as the front frame portion to cover the front opening.

[0012] In the present invention, In the extended loading platform, it is preferable that the extended horizontal frame portion be positioned laterally outside the horizontal frame portion in the extended released position.

[0013] When the extended horizontal frame portion of the extended cargo bed in the extended release position enters the inside of the horizontal frame portion of the cargo bed, the extended horizontal frame portion is likely to become an obstacle when loading luggage onto the cargo bed. With this configuration, the extended horizontal frame portion is positioned outside the horizontal frame portion of the cargo bed, so the extended horizontal frame portion does not become an obstacle when loading luggage onto the cargo bed, making it easier to load luggage onto the cargo bed.

[0014] In the present invention, It is preferable that the rear seat be provided in the rear passenger space and have a seat portion and a backrest portion, the backrest portion being attached to the outer surface of the extended cargo bed, and that when the extended cargo bed is changed to the cargo bed extension position, it folds down onto the seat portion to assume a stored position, and when the extended cargo bed is changed to the extension release position, it stands up above the seat portion to assume a usable position.

[0015] When the extended cargo bed is changed to the cargo bed extended position, the backrest portion is changed to the stored position by the extended cargo bed entering the rear boarding space, so there is no need to take the time to change the backrest portion to the stored position to utilize the rear boarding space as installation space for the extended cargo bed. Also, when the extended cargo bed is changed to the cargo bed extended position, the backrest portion is changed to the in-use position by the extended cargo bed exiting the rear boarding space, so there is no need to take the time to return the backrest portion to the in-use position to make the seat usable. Since there is no need to take the time to change the position of the backrest, it is easy to change the extended cargo bed between the cargo bed extended position and the extension released position.

[0020] [Cargo bed, cargo bed extension] As shown in FIGS. 1 and 2, a loading platform 20 and an extension loading platform 21 are provided at the rear of the traveling vehicle body 4, and the loading platform 20 can be extended by the extension loading platform 21.

[0021] 1 and 2, the cargo bed 20 is provided rearward of the passenger section 5. The cargo bed 20 is supported by the body frame 1 by connecting the rear side of the bottom of the cargo bed 20 to the left and right cargo bed support frame sections 1a of the body frame 1.

[0022] 1, 2, and 3, connecting portions 22 are formed on the left and right lower portions of the rear of the extended cargo bed 21, and the left and right connecting portions 22 are pivotally supported on the left and right cargo bed support frame portions 1a. The extended cargo bed 21 is supported by the vehicle body frame 1 in a state in which it can be swung around a pivot axis P that is along the width direction of the vehicle body and that is provided on the left and right connecting portions 22, and by being swung around the pivot axis P, its position can be changed between the cargo bed extended position shown in FIGS. 4 and 5 and the extension released position shown in FIGS. 1 and 2.

[0023] 1 and 2, the cargo bed 20 has a bottom plate portion 20a, side frame portions 20b rising from the bottom plate portion 20a on both sides of the bottom plate portion 20a, and a rear frame portion 20c rising from the bottom plate portion 20a at the rear of the bottom plate portion 20a. A front opening 20d that opens toward the front and outside is provided at the front of the cargo bed 20. The front opening 20d is formed by the bottom plate portion 20a and the left and right side frame portions 20b, and is located above the bottom plate portion 20a and between the left and right side frame portions 20b.

[0024] 1 and 3, the extended cargo bed 21 has an extended bottom plate portion 21a, extended horizontal frame portions 21b that rise from the extended bottom plate portion 21a on both sides of the extended bottom plate portion 21a, and an extended front frame portion 21c that rises from the extended bottom plate portion 21a in front of the extended bottom plate portion 21a. A rear opening 21d that opens toward the rear and outside is provided at the rear of the extended cargo bed 21. The rear opening 21d is formed by the extended bottom plate portion 21a and the left and right extended horizontal frame portions 21b, and is located above the extended bottom plate portion 21a and between the left and right extended horizontal frame portions 21b.

[0025] 1, the rear seat 12 provided in the rear passenger section 5b has a seat portion 12a and a backrest portion 12b. The seat portion 12a is supported by a seat support base 23 provided in the rear passenger section 5b. The backrest portion 12b is configured to be separable from the seat portion 12a and is attached to the outer surface side of the extended bottom plate portion 21a of the extended cargo bed 21.

[0026] 4 and 5, when the extended cargo bed 21 is swung downward toward the front of the vehicle body with the pivot axis P as the swing fulcrum, the extended cargo bed 21 passes between the left and right rear support frames 8r of the ROPS 8 and enters the rear passenger space 7 and lies down, the backrest portion 12b attached to the extended bottom plate portion 21a is lowered toward the front of the vehicle body by the extended cargo bed 21, and is placed in a stored position where it lies down on the seat portion 12a. Then, the extended cargo bed 21 is received and supported by the seat portion 12a via the backrest portion 12b, and the position of the extended cargo bed 21 is determined, and the extended cargo bed 21 extends forward from the cargo bed 20 and enters the rear passenger space 7 in an extended cargo bed position. When the extended cargo bed 21 is in the extended cargo bed position, the cargo bed 20 is extended forward by the extended cargo bed 21.

[0027] When the extended cargo bed 21 is in the cargo bed extended position, the rear opening 21d of the extended cargo bed 21 and the front opening 20d of the cargo bed 20 face each other, the bottom plate portion 20a of the cargo bed 20 is extended forward by the extended bottom plate portion 21a of the extended cargo bed 21, and the left and right lateral frame portions 20b of the cargo bed 20 are extended forward by the left and right extended lateral frame portions 21b of the extended cargo bed 21, making it possible to load luggage across the cargo bed 20 and the extended cargo bed 21. In other words, the luggage loading space of the multipurpose vehicle that can be loaded with luggage is expanded to the luggage loading space of the cargo bed 20 plus the luggage loading space of the extended cargo bed 21.

[0028] 1 and 2, when the extension bed 21 is swung upward toward the rear of the vehicle body with the pivot axis P as the swing fulcrum, and the extension bed 21 passes between the left and right rear support frames 8r of the ROPS 8 and stands out from the rear passenger space 7, the extension bed 21 assumes an extension-released position in which it overlaps with the front of the bed 20. When the extension bed 21 assumes the extension-released position, the extension of the bed 20 by the extension bed 21 is released.

[0029] When the extended cargo bed 21 is in the extension-released position, the extension of the bottom plate portion 20a of the cargo bed 20 by the extended bottom plate portion 21a is released, and the extension of the left and right lateral frame portions 20b of the cargo bed 20 by the extended lateral frame portions 21b is released, so that the cargo bed 20 can be loaded with luggage, but the extended cargo bed 21 cannot be loaded with luggage. In other words, the luggage loading space of the multipurpose vehicle that can be loaded with luggage is reduced to just the luggage loading space of the cargo bed 20.

[0030] As shown in Figure 1, when the extended cargo bed 21 is changed to the extension release position, the backrest 12b of the rear seat 12 is lifted from the seat 12a by the extended cargo bed 21, and the backrest 12b is returned from a position where it is resting on the seat 12a to a usage position in which it is positioned in a predetermined position above and behind the seat 12a. When the extended cargo bed 21 is changed to the extension release position, the extended cargo bed 21 moves out of the rear passenger space 7, allowing passengers to board the rear passenger section 5b. When the extended cargo bed 21 is changed to the extension release position, the backrest 12b is returned to the usage position, and the rear seat 12 becomes available for use.

[0031] 3, when the extension bed 21 is changed to the extension-released position, the extended bottom plate portion 21a of the extension bed 21 is positioned in an upright position forward of the bed 20, and the front opening 20d of the bed 20 is covered from the front by the extended bottom plate portion 21a. When the extension bed 21 is in the extension-released position and cargo is loaded onto the bed 20, the extended bottom plate portion 21a can be used as a front frame portion to close the front opening 20d.

[0032] 3, when the extension bed 21 is changed to the extension release position, the left and right extended horizontal frame portions 21b of the extension bed 21 are positioned laterally outside the horizontal frame portions 20b of the bed 20. When the extension bed 21 is in the extension release position and cargo is to be loaded onto the bed 20, the extended horizontal frame portions 21b do not obstruct the loading of the cargo.

[0033] [Another embodiment] (1) In the above embodiment, the extension bed 21 is changed between the bed extension position and the extension release position by swinging, but this is not limited to this. The extension bed may be held by the bed support frame 1a, the bed 20, etc. so as to be able to slide back and forth, and may be changed between the bed extension position and the extension release position by sliding back and forth.

[0034] (2) In the above-described embodiment, when the extended loading platform 21 is changed to the extended release position, the extended bottom plate portion 21a covers the front opening 20d of the loading platform 20, and the extended horizontal frame portion 21b is positioned laterally outside the horizontal frame portion 20b of the loading platform 20. However, this is not limited to this, and the extended bottom plate portion 21a may not cover the front opening 20d, and the extended horizontal frame portion 21b may be positioned laterally inside the horizontal frame portion 20b.

[0035] (3) In the above embodiment, an example is shown in which the backrest portion 12b is attached to the extension cargo bed 21, but this is not limited to this. The backrest portion 12b may not be attached to the extension cargo bed 21, and may be changed in position by an operation separate from the operation for changing the position of the extension cargo bed 21, thereby changing its position between a lying position that allows the extension cargo bed 21 to enter the rear passenger space 7 and an upright position that allows the rear seat 12 to be used.

[0036] (4) In the above embodiment, the extension platform 21 is manually operated to change its position. However, it may be changed in position by an actuator such as a cylinder or a motor. [Industrial Applicability]
