The present invention includes a step body that also serves as a fender attached to a vehicle body around a wheel, and the step body is disposed as a fender around a step state in which the step body is arranged to project outward from the vehicle body. The step body is attached to the vehicle body in such a manner that the state of the step body can be changed between the first fender state and the second portion located rearward of the wheel. A wheel interference prevention region surrounded by the first to third parts is formed, and when the step body is in a step state, the third part is the first part. In the vehicular step device arranged outside the vehicle body from the second part, when the step body is in a fender state, the wheel interference prevention A footrest member that can be disposed at a retracted position outside the region is provided, and when the step main body is in a step state, the footrest member can be disposed at a use position within the wheel interference prevention region, and an upper surface thereof. Is a tread.
According to the vehicle step device of the present invention, when the step body is in the fender state, the wheel interference prevention region surrounded by the first to third parts of the step body is formed, and the footrest member is the wheel interference prevention region. Since it is arrange | positioned in an outside retraction position, a step main body and a footrest member do not interfere with a wheel.
When the step body is in the step state, there is a space that constitutes a wheel interference prevention area between the third portion of the step body and the wheel, but the footrest that is disposed at the use position in the wheel interference prevention area Since the upper surface of the member is the tread surface, the space of the tread surface can be increased by covering the space with the footrest member.

The footrest member is preferably attached to the step body so as to be displaceable between the retracted position and the use position. Accordingly, the footrest member can be easily displaced between the use position and the retracted position without being separated from the step body.
In this case, the step body and the footrest member are arranged such that the footrest member is displaced between the retracted position and the use position in accordance with a state change between the fender state and the step state of the step body. It is preferable that an interlocking mechanism for interlocking is provided. Accordingly, the footrest member can be automatically displaced between the retracted position and the use position in accordance with the state change between the fender state and the step state of the step body.

The step body is attached to the vehicle body so as to be swingable about an axis along the front-rear direction of the vehicle body, and the state of the step body can be changed between a fender state and a step state by the swinging. When mounted on the step body so as to be swingable about an axis along the front-rear direction of the vehicle body and displaceable between the retracted position and the use position by the swing, and when the step body is in a fender state A holding member for holding the footrest member disposed at the retracted position so as not to swing due to its own weight is attached to the vehicle body, and the footrest member is in the middle of changing the state of the step body from the fender state to the step state. The footrest member and the holding portion are arranged such that the holding member releases the footrest member due to displacement toward the outside of the vehicle body. Preferably, the relative arrangement of the is set to.

Can be placed. That is, when changing the state of the step body from the fender state to the step state, the footrest member can be displaced to the use position without requiring a complicated configuration.
In this case, a support member that is displaceable between a support position that restricts swinging of the footrest member due to its own weight and a support release position that is spaced downward from the footrest member is provided to swing the step body. Accordingly, the support member is attached to the step body so as to be swingable about an axis along the longitudinal direction of the vehicle body so that the support member swings between a support position and a support release position. A transmission mechanism for transmitting the swing of the main body to the support member is provided, and during the state change from the fender state to the step state of the step main body, the support member is released before holding the footrest member by the holding member. The footrest member is displaced from the support release position to the support position, and the footrest member is disposed at the retracted position during the state change of the step body from the step state to the fender state. The support member preferably be displaced in the support release position from the support position before being.
As a result, during the state change from the fender state to the step state due to the swinging of the step body, the footrest member is supported by the support member so as not to swing due to its own weight after the holding by the holding member is released. When the main body swings toward the step state, the footrest member swings toward the use position while being supported by the support member, and when the step main body enters the step state, the footrest member is disposed at the use position. Therefore, the displacement of the step body from the fender state to the step state when the step body is changed to the use position of the foot member is supported by the support member, and the impact caused by the collision between the foot member and the other member such as the step body is performed. Can be prevented.
In addition, during the state change from the step state to the fender state due to the swinging of the step body, the footrest member swings from the use position to the retracted position while being supported by the support member, and further, the step body is directed to the fender state. By swinging, the footrest member reaches a position where it can be held by the holding member. When the step body is in the stepped state, the footrest member is held by the holding member and the support of the footrest member by the support member is released. That is, when changing the state of the step body from the step state to the fender state, the footrest member can be automatically displaced to the retracted position without requiring a complicated configuration.

  According to the vehicle step device of the present invention, by increasing the area of the tread surface of the step main body that also serves as a fender when in a step state without requiring a complicated configuration, an operator who puts a foot on the step surface is stabilized. Work efficiency can be improved.

Each gear box 13 is attached to a portion near the lower end of the step body 10 so as to swing together by welding or the like. As a result, the step body 10 can swing around the axis of the first support shaft 12 along the front-rear direction.

  When the step body 10 is in a fender state, a plate-like footrest member 20 that can be disposed at a retracted position outside the wheel interference prevention area A in a side view is provided. The footrest member 20 is not limited to a plate shape, and may be a lattice shape, for example. When the step body 10 is in the step state, the footrest member 20 can be disposed at a use position in the wheel interference prevention area A in plan view, and the upper surface thereof is the tread surface 20A. As shown in FIG. 5, the footrest member 20 of the present embodiment has a substantially rectangular plate shape, is located on the outer side of the vehicle body 4 at the use position, and has a first edge 20α along the front-rear direction and a front-rear end. The second and third edges 20β and 20γ are positioned along the left-right direction, and the fourth edge 20δ is positioned on the inner side of the vehicle body 4 and extends along the front-rear direction. Since the corner portion to be cut is notched, the vicinity of the front and rear ends of the fourth edge 20δ is a stepped portion 20δ '. On the tread surface 20A, the feet of the operator who takes in and out the articles in the storage 6 are placed. In the present embodiment, as shown in FIGS. 1 and 2, the side walls 4 ′ and 4 ″ constituting the vehicle body 4 before and after the step body 10 constitute the framework of the vehicle body 4 below the storage 6. It is attached to the member to be able to swing around the longitudinal axis and can be changed between a step state in which it is arranged to project outward from the vehicle body 4 and a state that functions as a side wall of the vehicle body 4. Yes.

  The footrest member 20 is attached to the step body 10 through a hinge 21 so as to be swingable about an axis along the front-rear direction of the vehicle body 4, and can be displaced between a retracted position and a use position by the swing. Yes. An interlock that links the step body 10 and the footrest member 20 so that the footrest member 20 is displaced between the use position and the retracted position in accordance with a change in state between the step state and the fender state of the step body 10. A mechanism 40 is provided. The interlocking mechanism 40 of this embodiment has a pair of front and rear holding members 41 and a pair of front and rear support members 42.

  As shown in FIG. 6, each holding member 41 includes a mold member having a side wall 41a and a bottom wall 41b, and a friction reducing material 41c such as nylon attached on the bottom wall 41b, and constitutes the vehicle body 4. The columnar member 4a is attached via a rivet or the like. When the step body 10 is in the fender state, the stepped portion 20δ ′ of the fourth edge 20δ of the footrest member 20 disposed at the retracted position is placed on the friction reducing material 41c of the both holding members 41, thereby The footrest member 20 is held by the holding member 41 so as not to swing due to its own weight. When the step body 10 swings from the fender state to the step state, the footrest member 20 is displaced toward the outer side of the vehicle body 4 due to the swinging, and when the amount of displacement exceeds a certain amount, the footrest member 20 is placed on the footrest. The holding of the member 20 is released. In other words, the footrest member 20 is released from being held by the holding member 41 due to the displacement of the footrest member 20 toward the outside of the vehicle body during the state change from the fender state to the step state of the step body 10. The relative arrangement of the member 20 and the holding member 41 is set.

  Each support member 42 includes a support bar 42a having a bent shape, and support rollers 42b and 42c attached to the front end and both ends of the support bar 42a so as to be rotatable about the longitudinal axis. The support member 42 is disposed at a position where it does not interfere with the holding member 41, and is disposed between the front and rear of both the holding members 41 in the present embodiment. The base end of each support member 42 is attached to the second support shaft 43 that is supported by the gear box 13 so that the axial direction is the front-rear direction. The second support shaft 43 is rotatable about the axis with respect to the gear box 13. Since the gear box 13 swings along with the step body 10, the support member 42 is attached to the step body 10 so as to be swingable about an axis along the front-rear direction of the vehicle body 4.

  A transmission mechanism 44 that transmits the swing of the step body 10 to the support member 42 is provided so that the support member 42 swings according to the swing of the step body 10. The transmission mechanism 44 of the present embodiment is attached to the first support shaft 12 so as not to rotate relative to the first support shaft 12 and to be engaged with the first gear 44a and not relative to the second support shaft 43. And a second gear 44b. As a result, when the step body 10 swings and the second support shaft 43 revolves around the first support shaft 12, the second support shaft 43 is centered on its own axis together with the second gear 44b meshing with the first gear 44a. The support member 42 is swung by the rotation of the second support shaft 43.

  The support member 42 can be displaced between the support position that restricts the swinging by the footrest member 20 and the support release position that is spaced downward from the footrest member 20 by the swinging motion. Accordingly, it swings between the support position and the support release position. That is, as shown in FIG. 6, when the step body 10 is in a fender state and the footrest member 20 is in the retracted position, the roller 42 b at the tip of the support member 42 is disposed below the footrest member 20. As shown in FIG. 7, when the swinging amount of the step body 10 from the fender state to the step state is small, the roller 42b at the tip of the support member 42 is closer to the footrest member 20 than when the step body 10 is in the fender state. The As shown in FIG. 8, in a state where the swinging amount of the step body 10 from the fender state to the step state is large and the holding member 41 is released from the holding member 41, the roller 42 b at the tip of the supporting member 42 is used as the footing member. The footrest member 20 is supported by the support member 42 so as to be restricted from swinging due to its own weight. As shown in FIG. 9, the support member 42 is disposed below the footrest member 20 so that the footrest member 20 is located at the use position when the step body 10 is in the step state. At this time, the roller 42 b at the tip of the support member 42 contacts the side plate 10 d of the step body 10, and the roller 42 c between both ends contacts the lower surface of the footrest member 20, whereby the footrest member 20 passes through the support member 42. Are supported by the step body 10.

  When the step body 10 swings from the fender state toward the step state, the footrest member 20 initially slides outward on the holding member 41 and swings downward as the step body 10 swings. The support member 42 swings as the step body 10 swings, and the roller 42b at the tip of the support member 42 is displaced upward. When the swinging amount of the step main body 10 increases, before the holding of the footrest member 20 by the holding member 41 is released, the roller 42b comes into contact with the lower surface of the footrest member 20, so that the footrest member 20 is supported by the support member 42. Is supported by That is, during the state change of the step body 10 from the fender state to the step state, the support member 42 is displaced from the support release position to the support position before releasing the holding of the footrest member 20 by the holding member 41. When the swinging amount of the step body 10 further increases, the roller 42b that comes into contact with the lower surface of the footrest member 20 due to the swinging of the support member 42 gradually approaches the swinging center of the footrest member 20, whereby the footrest member 20 The step 20δ ′ of the fourth edge 20δ is initially directed upward, and is positioned above the holding member 41 when positioned on the vehicle body inner side relative to the holding member 41, and is located outside the vehicle body relative to the holding member 41. After being located on the side, it is displaced downward. After that, when the step body 10 is in the step state, the rollers 42c between the both ends of the support member 42 come into contact with the lower surface of the footrest member 20, and the footrest member 20 is displaced to the use position.

  When the step body 10 swings from the step state toward the fender state, the rollers 42c between the both ends of the support member 42 initially contact the lower surface of the footrest member 20, and the support member 42 increases when the swing amount of the step body 10 increases. Also, the roller 42b at the tip comes into contact with it by swinging. When the swing amount of the step body 10 further increases, the roller 42b that contacts the lower surface of the footrest member 20 gradually moves away from the swing center of the footrest member 20 due to the swinging of the support member 42. The stepped portion 20δ ′ of the fourth edge 20δ is initially directed upward and then directed downward when positioned on the vehicle body inward side of the holding member 41. When the swinging amount of the step body 10 further increases, the roller 42 b is positioned below the footrest member 20, the support member 42 is displaced to the support release position, and the footrest member 20 is held by the holding member 41. When the step body 10 further swings toward the fender state, the stepped portion 20δ ′ of the footrest member 20 slides on the holding member 41 toward the inside of the vehicle body. Thereafter, when the holding member 41 is in the fender state, the footrest member 20 is displaced to the retracted position. That is, during the state change of the step body 10 from the step state to the fender state, the support member 42 is displaced from the support position to the support release position before the footrest member 20 is disposed at the retracted position.

According to the vehicle step device S, when the step body 10 is in the fender state, the wheel interference prevention region A surrounded by the first to third portions 10A, 10B, and 10C of the step body 10 is formed, and the foot Since the mounting member 20 is disposed at the retracted position outside the wheel interference prevention area A, the step body 10 and the foot mounting member 20 do not interfere with the wheel 3. When the step body 10 is in the step state, there is a space that forms the wheel interference prevention area A between the third portion 10C of the step body 10 and the wheel 3, but the use position in the wheel interference prevention area A Since the upper surface of the footrest member 20 disposed on the foot is the tread surface 20A, the area of the tread surface 20A can be increased by covering the space with the footrest member 20.
In addition, since the footrest member 20 is attached to the step body 10 so as to be displaceable between the retracted position and the use position, the footrest member 20 can be easily moved to the retracted position and the use position without being separated from the step body 10. Can be displaced between. Further, since the interlocking mechanism 40 displaces the footrest member 20 between the use position and the retracted position according to the state change between the step state and the fender state of the step body 10, according to the state change of the step body 10. Thus, the footrest member 20 can be automatically displaced between the use position and the retracted position.
During the state change from the fender state to the step state due to the swinging of the step body 10, the footrest member 20 is swung around the axis along the front-rear direction of the vehicle body 4 after the holding by the holding member 41 is released. Can be placed in position. That is, when changing the state of the step body 10 from the fender state to the step state, the footrest member 20 can be displaced to the use position without requiring a complicated configuration. Further, during the state change from the fender state to the step state due to the swinging of the step body 10, the footrest member 20 is supported by the support member 42 so as not to swing due to its own weight after the holding by the holding member 41 is released. Further, when the step body 10 swings toward the step state, the footrest member 20 swings toward the use position while being supported by the support member 42, and when the step body 10 enters the step state, the footrest member 20 is Arranged at the use position. Therefore, the support member 42 is used to support the displacement of the footrest member 20 to the use position when the step body 10 is changed from the fender state to the step state, and the footrest member 20 and other members such as the step body 10 Can prevent the impact caused by the collision. Further, during the state change from the step state to the fender state due to the swinging of the step body 10, the footrest member 20 swings from the use position to the retracted position while being supported by the support member 42, and the step body 10 is further moved. By swinging toward the fender state, the footrest member 20 reaches a position where it can be held by the holding member 41, and when the step body 10 is in the step state, the footrest member 20 is held by the holding member 41 and by the support member 42. The support of the footrest member 20 is released. That is, when changing the state of the step body 10 from the step state to the fender state, the footrest member 20 can be automatically displaced to the retracted position without requiring a complicated configuration.

The present invention is not limited to the above embodiment. For example, the step body may be opened / closed by power using an actuator such as an electric motor or a fluid pressure cylinder instead of human power. In this case, the opening / closing door is also opened / closed using the actuator, and the opening / closing door is opened by a single switch operation. The step body may be changed between a step state and a fender state in conjunction with opening and closing.
The structure of the interlocking mechanism that links the step body and the footrest member is not particularly limited. For example, the step body is changed between the step state and the fender state by the actuator, and the footrest member is also retracted from the use position by the actuator. The footrest member may be displaced in conjunction with a change in the state of the step body by a single switch operation.
The structure of the transmission mechanism that transmits the swing of the step body to the support member is not particularly limited. For example, the transmission may be transmitted via a cam, a friction transmission mechanism, or the like instead of the gear as in the above embodiment.
An interlocking mechanism for interlocking the step body and the footrest member is not essential, and the change of the state of the step body and the displacement of the footrest member may be performed individually by human power or power.
The retracted position of the footrest member is not particularly limited as long as it is outside the wheel interference prevention region. For example, when the step body is in a fender state, the position overlapping the third portion of the step body in a side view is set as the retracted position. The member may be attached to the step body so as to be slidable up and down, and may be displaced to the use position by sliding downward from the retracted position. In this case, the footrest member may be disposed at the use position when the step body is in the fender state, so that the footrest member does not interfere with the wheel when the step body is displaced to the step state or when the wheel is replaced. It may be displaced to the retracted position and displaced to the use position when the step body is in the step state.
The footrest member is not limited to those supported by the step body.
