DETAILED DESCRIPTION OF THE INVENTION

[0015] Next, embodiments of the present invention will be described with reference to the accompanying drawings to facilitate understanding of the present invention. Note that in the drawings, parts that are not relevant to the description may be omitted.

[0016] A camper shell 10 according to one embodiment of the present invention is detachably loaded onto the bed of a light truck 20, for example, and configured as a camper van 22. As shown in FIG. 1, the camping shell 10 has a space S formed inside when in use, and as shown in FIG. 2, is folded up to a small size when stored.

[0017] The camping shell 10 includes a floor forming portion 30, a ceiling forming portion 40, a left side expansion space forming portion 50, a right side expansion space forming portion 60, lower linear actuators 70a, 70b, upper linear actuators 72a, 72b, slide rails 74a, 74b, and a locking mechanism (not shown).

[0018] 3, the floor surface forming section 30 is a frame for forming the floor surface, which is made up of rod-shaped members 302a to 302l such as square pipes. The rod-shaped members 302a to 302l are arranged at positions corresponding to the sides of a rectangular parallelepiped whose longitudinal direction is the front-rear direction of the vehicle body.

[0019] The ceiling forming section 40 is a frame for forming the ceiling, and is made up of rod-shaped members 402a to 402l, such as square pipes. The rod-shaped members 402a to 402l are arranged at positions corresponding to the sides of a rectangular parallelepiped whose longitudinal direction is the front-rear direction of the vehicle body. The ceiling forming portion 40 has substantially the same size as the floor surface forming portion 30 in plan view.

[0020] The left side extension space forming portion (an example of a first extension space forming portion) 50 is a frame that protrudes further to the left (outside) of the vehicle body than the floor forming portion 30 and the ceiling forming portion 40. The left expansion space forming portion 50 has a lower deployment frame 502 and an upper deployment frame 504 .

[0021] The lower deployment frame 502 is made up of a plurality of rod-shaped members 502a to 502k. The rod-shaped member 502a is a member that extends outward from the rod-shaped member 502c with a gap therebetween. The rod-shaped member 502b is a member that extends above the rod-shaped member 502a with a gap therebetween. The rod-shaped member 502c extends along the rod-shaped member 302b located on the upper left side of the floor surface forming unit 30. The rod-shaped member 502c and the rod-shaped member 302b are connected via a plurality of lower hinges HLa (see FIG. 1) that are spaced apart in the longitudinal direction. Therefore, the lower unfolding frame 502 can rotate relative to the floor surface forming unit 30 around a lower rotation axis AXLa, which is the rotation axis of the lower hinges HLa. Rod-shaped members 502d, 502e, 502h, 502k and rod-shaped members 502f, 502g, 502i, 502j are located at the rear and front of the loading platform, respectively, and are configured to have a rectangular shape when viewed from the rear side of the vehicle, to which the ends of rod-shaped members 502a to 502c are fixed.

[0022] It is preferable that the lengths of the rod-shaped members 502h, 502k and the rod-shaped members 502i, 502j are each half that of the rod-shaped member 302f. However, "half" here does not mean half in the strict sense. In other words, "half" means "substantially half," allowing for design and manufacturing errors (the same applies hereinafter). Specifically, for example, the dimensions may have an error within the range of -5 to +5%.

[0023] The upper deployment frame 504 is made up of a plurality of rod-shaped members 504a to 504k, and is substantially symmetrical to the lower deployment frame 502 in the vertical direction. The rod-shaped member 504a extends below the rod-shaped member 504b at a distance. The rod-shaped member 504a is located above the rod-shaped member 502b, which is located above and outside the lower unfolding frame 502, and is connected to the rod-shaped member 502b via a plurality of intermediate hinges HMa (see FIG. 1) that are provided at intervals in the longitudinal direction. Therefore, the upper unfolding frame 504 and the lower unfolding frame 502 can rotate relative to each other around intermediate rotation axes AXMa, which are the rotation axes of the intermediate hinges HMa. The rod-shaped member 504b is a member that extends outward from the rod-shaped member 504c with a gap therebetween. The rod-shaped member 504c extends along the rod-shaped member 402a located below and to the left of the ceiling forming unit 40. The rod-shaped member 504c and the rod-shaped member 402a are connected via a plurality of upper hinges HUa (see FIG. 1) that are spaced apart in the longitudinal direction. Therefore, the upper unfolding frame 504 can rotate relative to the ceiling forming unit 40 around an upper rotation axis AXUa, which is the rotation axis of the upper hinges HUa. Rod-shaped members 504d, 504e, 504h, 504k and rod-shaped members 504f, 504g, 504i, 504j are located at the rear and front of the loading platform, respectively, and are configured to have a rectangular shape when viewed from the rear side of the vehicle, to which the ends of rod-shaped members 504a to 504c are fixed.

[0024] It is preferable that the lengths of the rod-shaped members 504h and 504k and the rod-shaped members 504i and 504j are each half that of the rod-shaped member 402e.

[0025] As shown in FIG. 1, the right-side expansion space forming portion 60 is a frame that protrudes further to the right side of the vehicle body than the floor forming portion 30 and the ceiling forming portion 40 (the side opposite to the left-side expansion space forming portion 50). The right expansion space forming portion 60 has a lower deployment frame 602 and an upper deployment frame 604 . The lower unfolding frame 602 is rotatably mounted to the floor surface forming unit 30 by a lower hinge HLb, and the upper unfolding frame 604 is rotatably mounted to the floor surface forming unit 30 by an upper hinge HUb. The lower unfolding frame 602 and the upper unfolding frame 604 are rotatably mounted to each other by an intermediate hinge HMb. The right-side expansion space forming portion 60 is configured to be substantially symmetrical to the left-side expansion space forming portion 50, and therefore further detailed description thereof will be omitted.

[0026] The lower linear actuators (an example of a driving unit) 70a, 70b are, for example, electric linear actuators, as shown in FIGS. 1 and 2, and can rotate the lower deployment frames 502, 602 relative to the floor surface forming unit 30. The lower linear actuator 70a includes a motor (not shown), a base 702a, and a retractable member 704a. The motor is, for example, a DC motor. The base 702a has a conversion mechanism that converts the rotational motion of the motor shaft into linear motion, and is rotatably provided on the floor surface forming part 30. The advancing / retracting member 704a is a rod-shaped member that advances and retreats from the base 702a in response to the rotation of the motor. The tip of the advancing / retracting member 704a is directly or indirectly attached to the lower deployment frame 502. In addition, the tip of the advancing / retracting member 704a is rotatably attached to the lower deployment frame 502.

[0027] The lower linear actuator 70b has a motor (not shown), a base 702b, and a reciprocating member 704b. The lower linear actuator 70b is disposed substantially symmetrically to the lower linear actuator 70a, and the specific configuration is the same, so detailed description is omitted.

[0028] The upper linear actuators (one example of a driving unit) 72 a and 72 b are, for example, electrically operated linear actuators, and can rotate the upper deployment frames 504 and 604 relative to the ceiling forming unit 40 . The upper linear actuators 72a, 72b may be arranged substantially symmetrically with the lower linear actuators 70a, 70b. The upper linear actuator 72a has a motor (not shown), a base 722a, and a reciprocating member 724a. The motor is, for example, a DC motor. The base 722a has a conversion mechanism that converts the rotational motion of the motor shaft into linear motion, and is rotatably provided on the ceiling forming part 40. The advancing / retreating member 724a is a rod-shaped member that advances and retreats from the base 722a in response to the rotation of the motor. The tip of the advancing / retreating member 724a is directly or indirectly attached to the upper deployment frame 504. In addition, the tip of the advancing / retreating member 724a is rotatably attached to the upper deployment frame 504.

[0029] The upper linear actuator 72b has a motor (not shown), a base 722b, and a reciprocating member 724b. The upper linear actuator 72b is disposed substantially symmetrically to the upper linear actuator 72a, and the specific configuration is the same, so detailed description is omitted.

[0030] Additionally, the upper linear actuators 72a and 72b are not essential. That is, if the lower linear actuators 70a and 70b can output the necessary thrust, the upper linear actuators 72a and 72b can be omitted. The drive units are not limited to the lower linear actuators 70a, 70b and the upper linear actuators 72a, 72b, and may have any configuration as long as they can rotate the lower deployment frames 502, 602 and the upper deployment frames 504, 604. The drive units may also be manual.

[0031] The slide rails (an example of a guide portion) 74a and 74b can guide the movement of the ceiling forming portion 40 in the up and down direction. The slide rail 74a is disposed so as to extend vertically on the left side of the vehicle when viewed from the rear side. The lower end of the slide rail 74a is attached to the floor forming part 30, and the upper end is attached to the ceiling forming part 40. The slide rail 74b is disposed so as to extend vertically on the right side of the vehicle when viewed from the rear side. The lower end of the slide rail 74b is attached to the floor forming part 30, and the upper end is attached to the ceiling forming part 40.

[0032] A locking mechanism (not shown) can restrict the movement of each part so that it does not rotate when in use or stored. In particular, the locking mechanism can restrict the movement of at least one of the lower deployment frames 502 and 602 and the upper deployment frames 504 and 604 in the use state.

[0033] The camping shell 10 may further include a solar power generation panel provided on the upper surface of the ceiling forming portion 40.

[0034] Next, the operation of transforming the camping shell 10 from the stored state (folded state) shown in FIG. 2 to the use state (unfolded state) shown in FIG. 1 will be described with reference to FIGS. 4(A) to 4(E).

[0035] After the camper van 22 is parked and the user releases the locking mechanism, the motors of the lower linear actuators 70a, 70b and the upper linear actuators 72a, 72b are driven, causing the advancing and retracting members 704a, 704b and the advancing and retracting members 724a, 724b to advance, respectively.

[0036] As a result, the advancing and retreating members 704a and 704b rotate the lower unfolding frames 502 and 602, respectively, around the lower hinges HLa and HLb (lower rotation axes AXLa and AXLb shown in Figure 3), and the advancing and retreating members 724a and 724b rotate the upper unfolding frames 504 and 604, respectively, around the upper hinges HUa and HUb (upper rotation axes AXUa and AXUb).

[0037] As the lower deployment frame 502 and the upper deployment frame 504 rotate around the intermediate hinge HMa (intermediate rotation axis AXMa), and the lower deployment frame 602 and the upper deployment frame 604 rotate around the intermediate hinge HMb (intermediate rotation axis AXMb), the ceiling forming section 40 is guided by the slide rails 74a and 74b, so that the ceiling forming section 40 gradually rises as shown in Figures 4(B) to 4(D).

[0038] When the lower deployment frames 502, 602 and the upper deployment frames 504, 604 are rotated 90 degrees from the initial folded state (see FIG. 4(A)), a space S is formed inside as shown in FIG. 4(E).

[0039] The left-side expansion space forming portion 50 and the right-side expansion space forming portion 60 protrude outward from the cargo bed, forming the space Sa and the space Sb (see FIG. 3), respectively, so that a larger space S is secured compared to a camping shell that does not protrude from the cargo bed.

[0040] The user uses a locking mechanism (not shown) to restrict the movement of each part so that the camping shell 10 does not deform. The user uses the camping shell 10 after forming an entrance from the outside to the inside on the rear side. When folding from the in-use state, the above-described operations are reversed, so details are omitted.

[0041] In this way, according to the camping shell 10 of this embodiment, a space S is formed inside when in use, and is folded up when in a stored state.

[0042] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and all changes in conditions that do not depart from the gist of the present invention are within the scope of application of the present invention. The structure of the camping shell 10 described in the above embodiment can also be used to form a building. In other words, since it can be loaded onto a light truck and transported, it can also be considered a portable building with the above structure, and can be used as a shelter or temporary housing in the event of a disaster.
