  However, in the retractable slide slope disclosed in Patent Document 1, since the guide base is fixed on the floor at the rear of the passenger compartment, the guide base always exists on the floor. There is a risk that the freedom to use the car body will be limited.

  Further, in the retractable slide slope disclosed in Patent Document 1, since the guide base is provided separately from the slide slope unit, the number of parts increases and the manufacturing cost increases.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a slope unit structure that can reduce the manufacturing cost by eliminating the need for a guide base on the vehicle body.

  To achieve the above object, the present invention comprises a bracket attached to a vehicle body and a slope unit having one or more slopes and attached to the bracket. The bracket has a slide guide extending along a storage direction, and the bracket has a guide means that engages with the slide guide and supports the slope unit so as to be slidable and rotatable.

  According to the present invention, the slope unit is provided with the slide guide, and the bracket is provided with the guide means. Therefore, the slide guide on the vehicle body such as the guide base disclosed in Patent Document 1 is not necessary, and the storage surface of the slope unit is not uneven. For this reason, in this invention, the vehicle body which does not prevent the freedom of utilization of vehicle bodies, such as the loadability of a load, can be provided. Furthermore, in the present invention, by providing the guide means provided on the bracket so as to be rotatable with the slope unit, the slope unit can be inclined and grounded to the ground plane.

  In the present invention, one end along the axial direction of the bracket is rotatably attached to the vehicle body, and the guide means is provided at the other end along the axial direction of the bracket. A first unfolded state in which the slope unit is slid along the guide means toward the outside of the passenger compartment, and from the first unfolded state, one end of the bracket is directed toward the outside of the passenger compartment, and the slide guide is moved upward with the guide means as a pivot. By changing the form to the second deployed state in which the slope unit is grounded by rotating each, the storage unit is shifted to the deployed state.

  According to the present invention, the bracket is rotated outward from the passenger compartment, and the slope unit provided with the slide guide is rotated upward with the guide means as the rotation axis. For this reason, the slope unit can be deployed from the position close to the ground contact surface by the length from one end to the other end of the bracket, and the length of the slope unit along the vehicle front-rear direction can be shortened. Therefore, the slope unit can be reduced in size and weight.

  In addition, according to the present invention, it is possible to shift from the housed state of the slope unit in the passenger compartment to the first deployed state and the second deployed state by only the pulling operation of the slope unit, and the deployment work can be completed. Can be done with a single touch.

  Further, according to the present invention, the vehicle body includes a vehicle body floor, and the vehicle body floor is provided with a structure housing portion formed to be positioned below the vehicle body floor at the rear of the vehicle. The distance between the one end and the other end is provided so as to be substantially equal to the height of the vehicle body floor and the structure housing portion.

  According to the present invention, since the separation distance between the one end and the other end along the axial direction of the bracket is set to be substantially equal to the height dimension between the vehicle body floor and the structure housing portion, the slope By sliding the unit onto the vehicle body and storing it, the upper surface of the slope unit that functions as the loading surface of the trunk room can be formed substantially horizontally with respect to the ground. Accordingly, it is possible to secure the degree of freedom of loading of the load while taking advantage of the effect of providing the structure housing portion on the vehicle body.

  Furthermore, the present invention includes a second guide means for supporting the slope unit to be deployed from below in the first deployed state, wherein the second guide means is provided when the second deployed state is completed. It is formed so as to be positioned below the bracket, and is provided so as to be in contact with the vehicle body.

  According to the present invention, in the first deployed state, the deployed slope unit is supported from below by the second guide means, so that the deployed angle of the slope unit provided to be rotatable with respect to the bracket can be regulated. . Further, when the second unfolding state is completed, the second guide means is set to be positioned below the bracket, so that the second guide means becomes a contact point (fulcrum) with the vehicle body floor surface, and the second guide means The load of the slope unit and the load can be supported.

  Furthermore, in the present invention, the bracket includes a pair of brackets disposed on both sides along the vehicle width direction, and the one of the pair of brackets is between the one bracket and the other bracket. A support plate that connects the bracket and the other bracket is provided.

  According to the present invention, a pair of brackets are provided on both sides along the vehicle width direction, and the support plate is provided between one bracket and the other bracket. Thereby, when one end of the bracket is rotated to be in the second deployed state, the support plate may constitute a part of the slope unit and fill the region where the slope unit from one end to the other end of the bracket is not formed. it can.

  Furthermore, the present invention is characterized in that the slope unit has a slope extension portion that extends so as to overlap with the support plate in the vehicle front-rear direction in the second deployed state.

According to the present invention, one end of the bracket is rotatably attached to the vehicle body, and the slope unit is slidably attached to the other end. For example, when the slope unit is slid from a position close to the direction in which the slope unit is deployed by the distance from one end of the bracket to the other end, in the second deployed state, between the support plate and the slope unit. There is a risk of gaps or steps.
On the other hand, in this invention, the slope extension part extended so that it may overlap with the support plate of a bracket toward the vehicle body from the edge part of a slope unit is provided. Thereby, the clearance gap and level | step difference which generate | occur | produce between a bracket and a slope unit can be eliminated.

  Further, for example, it is possible to form only the support plate of the bracket that forms the slope shape between the slope unit and the vehicle body. However, the bracket support plate alone cannot withstand the load of the load, and the support plate may be deformed. Therefore, in the present invention, a slope extension portion is provided that extends from the end portion of the slope unit toward the vehicle body so as to partially overlap with the support plate of the bracket. Thereby, even if a heavy load is carried in or taken out by supporting the load of the load in cooperation with both the support plate of the bracket and the slope extension portion, the slope shape can be maintained.

  Furthermore, in the present invention, the slope unit includes a lock mechanism that prohibits sliding of the slope unit with respect to the bracket, and the lock mechanism is provided on either the support plate or the slope extension portion. And it has a projection protruding from one side to the other, and a locking hole provided on either the support plate or the slope extension and locking the projection. .

  In the second deployed state, the guide means attached to the other end of the bracket and the slide guide provided in the slope unit are slidable, and the slope unit slides in the storage direction, It will be forced to carry in or out of the luggage by the slope unit. According to the present invention, by providing a lock mechanism that prohibits sliding of the bracket and the slope unit, it is possible to prevent unintentional sliding of the slope unit in the storage direction when carrying in or taking out the load by the slope unit. , It is possible to carry in or out the luggage stably. Furthermore, the locking mechanism of the present invention can prohibit the sliding of the slope unit with a simple mechanism of locking the protrusion inserted into the locking hole.

  Furthermore, in the present invention, the support plate is provided so as to be supported from the lower side with respect to the slope extension portion, and a lock release prohibiting mechanism for prohibiting the removal of the protrusion from the locking hole is provided. It is characterized by that.

  For example, since the protrusion and the locking hole of the lock mechanism are only locked, when changing the form of the slope unit from the standing state to the deployed state, and conversely from the deployed state to the standing state, The locking state of the protrusion and the locking hole is released, the lock becomes invalid, and there is a risk that the slope unit may turn freely with the guide means attached to the other end of the bracket as a turning shaft. . In addition, when a large force is applied in the storage direction of the slope unit in the second deployed state, the locking state of the locking mechanism protrusion and the locking hole is released, the lock becomes invalid, and the slope unit slides in the storage direction. There is a risk of it.

  According to the present invention, fixing of the bracket and the slope unit is maintained by providing the lock release prohibiting mechanism that prevents the protrusion of the lock mechanism from falling out of the locking hole. Thereby, when changing the form of the slope unit or in the second deployed state, it is possible to prevent the lock mechanism from being unlocked.

  Further, according to the present invention, the support plate is provided so as to be supported from below with respect to the slope extension portion, and provided with the lock release prohibiting mechanism, the slope extension portion and the lock release prohibition mechanism located above the support plate are provided. The rotation of the guide means and the slide guide is prohibited, and the slope unit can be prevented from being bent downward with the point where the guide means and the slide guide are fitted in the second deployed state as an axis.

  Furthermore, the present invention is characterized in that a second lock mechanism that locks the slope unit in a standing state is provided on a side portion inside the vehicle body.

  According to the present invention, in the standing state of the slope unit, the second lock mechanism that locks the other end of the slope unit on the side portion inside the vehicle body is provided. As a result, the slope unit is supported by the second lock mechanism against the slope unit that maintains the standing state by prohibiting the downward sliding of the slope unit by the lock mechanism and the lock release prohibiting mechanism provided on the bracket. In addition, the rising state of the slope unit can be stably maintained by forming the rising state of the slope unit in cooperation with the lock mechanism and the lock release prohibiting mechanism.

  Furthermore, the present invention is characterized in that a handle is provided at a vehicle rear end portion of the slope unit that is grounded with respect to the ground plane.

  According to the present invention, in the second deployed state, the handle is provided at the vehicle rear end of the slope unit that is grounded to the ground plane. As a result, when the slope unit is deployed outside from the stored state in the vehicle compartment, the operator can easily pull out the slope unit and deploy it without gripping the body toward the back of the vehicle body. it can.

  Furthermore, the present invention is characterized in that a recess is formed at a vehicle rear end portion of the slope unit that is grounded with respect to the ground plane.

  According to the present invention, in the second deployed state, the recess is formed at the vehicle rear end of the slope unit that is grounded with respect to the ground plane. As a result, even if the worker is short in height, the slope unit can be easily changed from the standing state to another form such as a deployed state by placing a hand on the recess.

  Still further, in the present invention, the slide guide is formed with a guide groove extending along a deployment / housing direction of the slope unit, and the guide means is a guide roller that rotates along the guide groove. Features.

  According to the present invention, the guide roller rotates along the guide groove of the slide guide, so that the displacement operation and the rotation operation of the slope unit in the deployment / storage direction can be easily and smoothly performed.

  Furthermore, according to the present invention, the first unfolded state can be achieved by sliding the slope unit horizontally stored in the vehicle interior toward the outside of the vehicle compartment while the guide roller is engaged with the guide groove. Furthermore, the present invention provides a slope unit that is slid and deployed by rotating the other end of the bracket toward the outside of the passenger compartment while maintaining the engaged state where the guide roller engages with the guide groove. It can be set as the 2nd unfolding state by making it ground on a grounding surface.

  In the present invention, it is possible to obtain a slope unit structure that can reduce the manufacturing cost by eliminating the guide base on the vehicle body.

Since it can be completed, from storage to deployment can be performed with one touch.

  Furthermore, in the present embodiment, as shown in FIG. 5A, in the horizontal storage state of the slope unit 18, the separation distance (the bracket height) between the one end 44a and the other end 44b along the axial direction of the bracket 44. ) Is set to be equal to the height dimension (inclined surface height) of the inclined surface 78 (bracket height = inclined surface height), so that the slope unit 18 can be slid to the vehicle body 12 and stored horizontally to load the trunk room. The upper surface of the slope unit 18 that functions as a surface can be formed substantially horizontally with respect to the ground (the ground contact surface 22). Accordingly, it is possible to ensure the degree of freedom of loading the load while taking advantage of the inclined surface 78 provided on the vehicle body floor 46 of the vehicle body 12.

  In the present embodiment, the structure housing portion is exemplified by the case where the vehicle body floor 46 is provided with an inclined surface 78 (see FIG. 2) that is inclined so as to be positioned downward toward the rear of the vehicle. It is not limited to. For example, as shown in FIG. 16, a recess 92 that is recessed substantially vertically downward toward the lower side (grounding surface 22) of the vehicle body floor 46 is provided, and a load is mounted on the inner bottom surface 94 of the recess 92. You may make it do. By doing in this way, for example, even if it is a vehicle whose vehicle height is lower than a height system wagon, there exists an advantage which can secure a structure storage part easily. Further, the distance between the one end 44 a and the other end 44 b along the axial direction of the bracket 44 is provided to be substantially equal to the height between the vehicle body floor 46 and the inner bottom surface 94 of the recess 92.

  Furthermore, in the present embodiment, in the first deployed state, the slope unit 18 that is deployed is supported from below by the roller member 64 of the second guide means 58, so that the slope unit is provided so as to be rotatable with respect to the bracket 44. 18 deployment angles can be regulated. Further, when the second unfolded state is completed, the second guide means 58 is set so as to be positioned below the bracket 44, so that the second guide means 58 becomes a grounding point (fulcrum) with respect to the vehicle body floor surface. The load of the slope unit 18 and the load can be supported by the guide means 58.

  Furthermore, in this embodiment, a pair of brackets 44 are provided on both sides along the vehicle width direction, and the support plate 36 is provided between one bracket 44 and the other bracket 44. Thereby, in this embodiment, when the one end 44a of the bracket 44 rotates and it will be in a 2nd deployment state, the support plate 36 will comprise a part of slope unit 18, and the other end 44b from the one end 44a of the bracket 44 will be shown. The region where the slope unit 18 is not formed can be filled.

  One end 44a of the bracket 44 is rotatably attached to the vehicle body 12, and the slope unit 18 is slidably attached to the other end 44b. For example, when the slope unit 18 is slid from a position close to the direction in which the slope unit 18 is deployed by the distance from the one end 44a to the other end 44b of the bracket 44, in the second deployed state, There may be a gap or a step between the slope unit 18 and the slope unit 18.

  On the other hand, in this embodiment, the slope extension part 30 extended so that it may overlap with the support plate 36 of the bracket 44 toward the vehicle body 12 from the vehicle front end part 18a of the slope unit 18 is provided. Thereby, in this embodiment, the clearance gap and level | step difference which generate | occur | produce between the bracket 44 and the slope unit 18 can be eliminated.

  Further, for example, only the support plate 36 of the bracket 44 can form the slope shape between the slope unit 18 and the vehicle body 12. However, only the support plate 36 of the bracket 44 cannot withstand the load of the load, and the support plate 36 may be deformed.

  Therefore, in the present embodiment, a slope extension 30 is provided that extends from the vehicle front end 18a of the slope unit 18 toward the vehicle body 12 so as to partially overlap with the support plate 36 of the bracket 44. Thereby, in this embodiment, even when a heavy load is carried in or taken out by supporting the load of the load in cooperation with both the support plate 36 of the bracket 44 and the slope extension 30, the slope shape. Can be maintained.

  In the second deployed state, the first guide means 50 (guide roller 56) attached to the other end 44b of the bracket 44 and the slide guide 32 (guide groove 34) provided in the slope unit 18 are slidable. Yes, the slope unit 18 slides in the storage direction, and it is forced to carry in or carry out the luggage by the slope unit 18 in an unstable state. Therefore, in the present embodiment, the first lock mechanism 66 that prohibits the sliding of the bracket 44 and the slope unit 18 is provided, so that the slope unit 18 is unintentionally stored in the storage direction when the load is carried in or out by the slope unit 18. Can be prevented, and the load can be carried in or out stably. Furthermore, the first lock mechanism 66 of the present embodiment can inhibit the slope unit 18 from sliding with a simple mechanism of locking the tip of the lock pin 70 inserted into the locking hole 74.

  For example, since the lock pin 70 and the locking hole 74 of the first lock mechanism 66 are only locked, the slope unit 18 is configured from the standing state to the deployed state, and conversely from the deployed state to the standing state. Is changed, the lock state of the lock pin 70 and the lock hole 74 of the first lock mechanism 66 is released, the lock becomes invalid, and the first guide means 50 attached to the other end 44b of the bracket 44 is moved around the rotation shaft. As a result, the slope unit 18 may be in an unstable state in which the slope unit 18 is freely rotatable. In addition, when a large force is applied in the storage direction of the slope unit 18 in the second deployed state, the locking state between the lock pin 70 and the locking hole 74 of the first lock mechanism 66 is released, and the lock becomes invalid. There is a possibility that the slope unit 18 slides in the storage direction.

  Thus, in the present embodiment, the bracket is provided by providing a lock release prohibiting mechanism (the locking plate 76 and the locking hole 74) that prevents the lock pin 70 of the first lock mechanism 66 from being pulled out of the locking hole 74. The fixed state of 44 and the slope unit 18 is maintained. Thereby, it is possible to prevent the lock of the first lock mechanism 66 from being released when the form of the slope unit 18 is changed or in the second deployed state.

  Furthermore, in the present embodiment, the support plate 36 is provided so as to support the slope extension 30 from below, and is provided with the above-described lock release prohibiting mechanism (the lock plate 76 and the lock hole 74). Since the slope extension 30 and the lock release prohibiting mechanism located above the plate 36 prohibit the rotation of the first guide means 50 and the slide guide 32, the first guide means 50 and the slide guide 32 in the second deployed state It is possible to prevent the slope unit 18 from being bent downward with the engagement point as an axis.

  Furthermore, in the present embodiment, the second lock mechanism 80 that locks the upper portion (the other end) of the slope unit 18 to the side portion 12a inside the vehicle body 12 when the slope unit 18 is stowed and stowed is provided. As a result, the first lock mechanism 66 and the lock release prohibiting mechanism provided on the bracket 44 further prevent the slope unit 18 from sliding downward and maintain the upright storage state. The slope unit 12 is supported by the lock mechanism 80, and the upright state of the slope unit 18 is stably maintained by forming the upright state of the slope unit 18 in cooperation with the second lock mechanism 80 and the unlocking prohibiting mechanism. can do.

  Furthermore, in the present embodiment, the handle 40 is provided at the vehicle rear end 38 of the slope unit 18 that is grounded to the ground plane 22 in the second deployed state. Thereby, in this embodiment, when the slope unit 18 is deployed outside the vehicle from the horizontal storage state in the vehicle compartment 24, the operator holds the handle 40 without bending the body toward the back side of the vehicle body 12. The slope unit 18 can be easily pulled out of the vehicle and deployed.

  Furthermore, in the present embodiment, the recess 42 is formed at the vehicle rear end portion 38 of the slope unit 18 that is grounded with respect to the ground plane 22 in the second deployed state. Thereby, in this embodiment, even in a standing storage state where the slope unit 18 stands up, even a worker with a short height can touch the concave portion 42 to move the slope unit 18 from the standing storage state to the expanded state. It can be easily changed to the form.

  Furthermore, in this embodiment, the first unfolded state can be easily achieved by sliding the slope unit 18 horizontally stored in the vehicle compartment 24 toward the outside of the vehicle compartment while the guide roller 56 is engaged with the guide groove 34. It can be. Further, in the present embodiment, while maintaining the engagement state where the guide roller 56 engages with the guide groove 34, the other end 44b of the bracket 44 is rotated outwardly from the vehicle interior with the one end 44a of the bracket 44 as a rotation axis.
