Description

  The present invention relates to a wheelchair storage device for a vehicle for storing a wheelchair on the roof of the vehicle.

  As this type of vehicle wheelchair storage device, a wheelchair storage device disclosed in Patent Document 1 is known. This wheelchair storage device includes a base frame (fixed frame) that is a rectangular frame, a first frame (movable frame) that is a rectangular frame, and a second frame and a third frame (carrier) that are assembled vertically. And a fourth frame (protector) which is a horizontally long flat plate material. In the known technology, a fixed gantry is installed on the roof of a vehicle, and a movable gantry is connected to the fixed gantry so as to be slidable in the vehicle width direction (left-right direction). A carrier is connected to the movable base so as to be rotatable up and down, and a protector is attached to the carrier so as to be vertically slidable. This protector is a member disposed between the vehicle and the wheelchair and is locked to the wheel of the wheelchair while the wheelchair is being lifted.

  This wheelchair storage device is installed on the roof of the vehicle so that the lateral slide center of the movable frame is arranged near the entrance / exit on the driver's seat side. When the wheelchair is lifted, the movable base is slid to the right and protrudes from the roof like a bowl, and then the wheelchair is lifted straight at that position. At this time, after the carrier is rotated downward from the movable gantry, the protector is further slid vertically downward relative to the carrier suspended from the movable gantry. Next, after the wheelchair is placed face-to-face on the protector, the hook of the belt extending from the upper part of the movable frame is hung on an appropriate portion of the wheelchair. Then, the wheelchair is lifted by the winding mechanism installed on the upper part of the movable frame and locked to the protector, and both are lifted upward. After the wheelchair and the protector thus lifted are rotated together with the carrier and installed in the frame of the movable frame, the movable frame is slid to the left and stored on the roof of the vehicle.

  By the way, in the above-mentioned wheelchair storage device, the storage position of the wheelchair on the roof of the vehicle and the entrance / exit may be shifted in the vehicle front-rear direction. For example, if the storage position is located behind the entrance, the driver in the driver's seat must twist the body back and place the wheelchair on the protector next to the entrance / exit. It becomes the structure which requires time and effort. Thus, from the viewpoint of simplifying the lifting work, it is conceivable to slide the protector obliquely forward and downward with respect to the carrier during the lifting work. By doing so, even if the wheelchair storage position is shifted rearward from the entrance / exit, the wheelchair can be smoothly arranged at the facing position of the protector slid forward from the storage position.

JP 11-20554 A

  And in the above-mentioned reference example, the belt extended from the upper part of a movable mount frame is diagonally routed with the protector forward and downward of the vehicle. For example, the protector is provided with an adjuster member for directing the belt in an appropriate direction on the way. The adjuster member can be constituted by a shaft body that protrudes toward the wheelchair at the upper front portion of the protector, for example, and is disposed in front of the take-up mechanism during the lifting operation of the wheelchair. Therefore, after the belt is disposed obliquely forward and downward between the winding mechanism and the adjuster member, the belt is suspended downward from the adjuster member. Further, the adjuster member applies force in the direction of the winding center (left direction) to the belt so that the suspension position of the wheelchair is not greatly displaced from the winding center of the winding mechanism in the vehicle width direction (right direction). It is desirable that For example, by bending the front end (right end) of the adjuster member forward, a force can be applied to the belt in the winding center direction (left direction).

  However, in the configuration in which the adjuster member is bent forward, large friction may occur between the adjuster member and the belt when the belt is lifted. For this reason, during the lifting operation of the wheelchair, the belt is hung by the frictional force generated between the adjuster member and the protector may be lifted up prior to locking with the wheelchair. . The present invention has been devised in view of the above points, and the problem to be solved by the present invention is that the protector is connected to the wheelchair while eliminating the positional deviation between the winding center of the belt and the suspension position of the wheelchair. It is to avoid lifting as much as possible prior to locking.

  As a means for solving the above-mentioned problems, a wheelchair storage device for a vehicle according to a first aspect of the present invention is a fixed base installed on the roof of a vehicle, and a frame-like movable connected to the fixed base so as to be movable in the vehicle width direction. A gantry, a carrier coupled to the movable gantry so as to be pivotable up and down, a protector coupled to the carrier so as to be obliquely movable, and a suspension device capable of lifting or suspending the wheelchair. The movable gantry can be displaced between a storage position where it overlaps with the fixed gantry and a use position that projects in the vehicle width direction from the fixed gantry in a state where the carrier and the protector are arranged within the frame. In the present invention, in the movable gantry at the use position, the protector is diagonally moved forward and downward from the original position where the protector is disposed on the upper side of the carrier rotated downward with respect to the movable gantry, and is disposed facing the wheelchair. Displace to possible position. In addition, the wheelchair is locked to the protector in the middle of being lifted by the belt of the suspension device, so that the protector is lifted to the original position while moving diagonally backward and upward of the vehicle together with the wheelchair. The wheelchair is pivoted upward together with the carrier and is disposed in the frame of the movable frame.

  In the present invention, the suspension device has a winding mechanism that winds the belt when the wheelchair is lifted. In addition, the winding center of the cylindrical portion that winds the belt in the winding mechanism in the winding mechanism and the suspension position of the wheelchair are displaced in the axial direction of the cylindrical portion of the winding mechanism. In some cases, an adjuster member that applies force to the belt in the direction of the winding center of the winding mechanism is provided. Thus, in the present invention, the wheelchair is lifted up while the positional deviation from the winding mechanism is corrected by the adjuster member. In this type of configuration, it is desirable that the protector can be avoided as much as possible from being lifted prior to locking with the wheelchair due to friction generated between the adjuster member and the belt.

  Therefore, in the present invention, the protector has a rail portion that extends in parallel to the oblique movement direction of the protector, the carrier has a roller portion that can rotate on the rail portion, and the protector is a roller pressed against the rail portion. It is set as the structure which moves diagonally with respect to a carrier, rotating a part. The rail portion is provided with a restricting portion that acts as a resistance when the roller portion rotates until the wheelchair is suspended while the wheelchair is lifted and restricts the oblique movement of the protector. In the present invention, the diagonal movement of the protector is restricted by the restricting portion until the wheelchair is locked to the protector. For this reason, even if friction occurs between the adjuster member and the belt, since the oblique movement of the protector itself is restricted, the belt lifts the wheelchair against the frictional force with the adjuster member.

  The wheelchair storage device for a vehicle according to a second aspect of the invention is the wheelchair storage device for a vehicle according to the first aspect, wherein the resistance of the restricting portion against the roller portion when the protector moves obliquely backward and upward of the vehicle, It is set to be larger than the resistance force of the restricting portion with respect to the roller portion when moving diagonally. In the present invention, by providing a difference in the resistance force of the restricting portion, the protector is prevented from being lifted prior to locking with the wheelchair as much as possible, and further smoothly obliquely forward and downward with respect to the carrier. Can move.

  The vehicle wheelchair storage device according to a third aspect of the present invention is the vehicle wheelchair storage device according to the first or second aspect, wherein the restricting portion is a protruding portion of the rail portion protruding toward the roller portion. In the present invention, it is possible to avoid as much as possible that the protector is lifted prior to locking with the wheelchair by the relatively simple restricting portion.

  The wheelchair storage device for a vehicle according to a fourth aspect of the invention is the wheelchair storage device for a vehicle according to the third aspect of the invention, wherein the rising angle of the restricting portion facing the roller portion when the protector moves obliquely rearward and upward is the vehicle It is set to be larger than the rising angle of the restricting portion facing the roller portion when moving obliquely forward and downward. In the present invention, the protector can be smoothly and diagonally moved forward and downward with respect to the carrier while avoiding as much as possible that the protector is lifted prior to locking with the wheelchair by the restriction portion having a relatively simple configuration. Can do.

  The wheelchair storage device for a vehicle according to a fifth aspect of the invention is the wheelchair storage device for a vehicle according to the third or fourth aspect, wherein the restricting portion is a flat contact that contacts the roller portion when the protector moves obliquely rearward and upward. A corner portion of the projecting portion having a contact surface portion and excluding the contact surface portion is curved. In the present invention, since the rotation of the roller portion is stopped and held at the contact surface portion of the restricting portion, it is possible to more reliably avoid lifting the roller portion prior to locking with the wheelchair. In addition, since the corners of the protruding portion excluding the contact surface are curved, the protector can be smoothly and obliquely moved relative to the carrier forward and downward of the vehicle.

  According to the first invention of the present invention, it is possible to avoid as much as possible that the protector is lifted prior to the engagement with the wheelchair while eliminating the positional deviation between the belt winding center and the wheelchair suspension position. . Further, according to the second invention, the protector can be smoothly and diagonally moved forward and downward while avoiding as much as possible that the protector is lifted prior to locking with the wheelchair. According to the third aspect of the present invention, it is possible to avoid the protector from being lifted prior to locking with the wheelchair as much as possible by the comparatively simple restricting portion. According to the fourth aspect of the present invention, the protector can be smoothly and diagonally moved forward and downward while avoiding as much as possible that the protector is lifted prior to locking with the wheelchair by the restriction portion having a relatively simple configuration. Can do. According to the fifth aspect of the present invention, the protector can be smoothly and obliquely moved further forward and downward of the vehicle while preferably avoiding being lifted prior to locking with the wheelchair.

  The connecting plate 46 is a flat plate-like member that connects the front shaft body 41 and the rear shaft body 43 at their tip portions (right end portions). The flange portion 44 is a flat plate-like member that connects the front shaft body 41 and the rear shaft body 43 at their base end portions (left end portions), and the back surface side of the flange portion 44 is bolted to the second support plate 24b. It has been stopped. 9, the second support plate 24b of the protector 24 is formed with slit-like long holes 24y extending in the vehicle front-rear direction at the upper part and the lower part, and the upper and lower long holes 24y have flange portions. A fixing bolt BM is passed. For this reason, the position of the adjuster member 40 in the vehicle front-rear direction can be adjusted using the long hole 24y of the second support plate 24b.

  With reference to FIG. 7, the adjuster member 40 is positioned at a position where the rear shaft body 43 can press the belt 31 horizontally forward in a state where the protector 24 is raised to the original position and is in the retreat limit position. Yes. Further, the bent portions of the front shaft body 41 and the rear shaft body 43 of the adjuster member 40 are positioned so as to be at the same position in the vehicle width direction as the winding center Mo of the drum 33 of the suspension device 30. For this reason, for example, when a large wheelchair K is lifted, if the suspension position Mr of the wheelchair K is displaced in the vehicle width direction (axial direction of the drum 33) with respect to the winding center Mo of the drum 33 of the suspension device 30, The belt 31 is hung on the inclined portion (front end side) of the rear shaft body 43. Thus, referring to FIG. 8, the pressing force F applied to the rear shaft body 43 from the belt 31 (the pressing force F caused by the weight of the protector 24 and the wheelchair K) is perpendicular to the inclined portion of the rear shaft body 43. Is broken down into a force Fs and a force Fb along the inclined portion of the rear shaft body 43. The belt 31 moves (slides) in the direction of the winding center Mo of the drum 33 along the inclined portion of the rear shaft body 43 by the force Fb along the inclined portion of the rear shaft body 43.

[Rail part]
4 and 9, the rail portion 60 is a flat plate-like member that can be pressed against the roller portions 51 and 52 of the carrier 22 to rotate them, and is provided with a regulating portion 70 described later. It has been. The rail portion 60 is inclined so as to be parallel to the oblique movement direction (the guide portion 22r and the rear frame 222) of the protector 24, and is disposed at a position where the rail portion 60 can contact the roller portions 51 and 52 of the carrier 22. Has been. That is, the rail portion 60 is disposed on the back side of the protector 24 and slightly behind the rear frame 222 of the carrier. Further, the upper end of the rail portion 60 is fixed to the rear portion of the upper frame portion 243 of the protector 24, and the lower end of the rail portion 60 is fixed to a corner portion from the front frame portion 241 to the lower frame portion 244. The portions excluding the upper end and the lower end of the rail portion 60 are not fixed to the protector 24 and can be appropriately bent and deformed (retracted) to the protector side by pressing from the roller portions 51 and 52.

  When the protector 24 moves obliquely with respect to the carrier 22, the rail portion 60 moves obliquely following the protector 24. The roller portions 51 and 52 corresponding to the carrier 22 are pressed against the rail portion 60 that moves obliquely and rotate. When the protector 24 is arranged on the upper portion (retreat limit position) of the carrier 22, both the pair of roller portions 51 and 52 are in contact with the rail portion 60. When the protector 24 is disposed at the lower end (advance limit position) of the carrier 22, only the lower roller portion 52 is in contact with the upper side of the rail portion 60.

[Regulation Department]
With reference to FIGS. 12 and 13, the restricting portion 70 is a portion that acts as a resistance when the lower roller portion 52 rotates with respect to the rail portion 60 and restricts the oblique movement of the protector 24. The restricting portion 70 is a substantially trapezoidal protruding portion that protrudes from the upper back surface of the rail portion 60, and includes an upper rising portion 72, a lower rising portion 76, and an upper bottom portion 74 formed between these rising portions. (Details of each part will be described later). With reference to FIGS. 9 to 11, the restricting portion 70 is located at a position where it can interfere with the lower roller portion 52 until the wheelchair K is locked to the protector 24 (restraining plate 24 x) while being lifted. Is provided. In the present embodiment, referring to FIG. 9, with reference to the state where the protector 24 is disposed at the lower end (advance limit position) of the carrier 22, the restricting portion 70 is located above the rail portion 60 and the lower roller portion 52. Place it directly under. At this time, the restricting portion 70 and the lower roller portion 52 may be in contact with each other, and a slight gap may be provided between them. Referring to FIGS. 10 and 13, when protector 24 attempts to move obliquely rearward and upward from the forward limit position, restricting portion 70 interferes with lower roller portion 52.

  Then, referring to FIG. 13, the upper rising portion 72 is disposed on the upper side facing the lower roller portion 52 when the protector 24 at the lower end (advance limit position) of the carrier 22 moves obliquely rearward and upward of the vehicle. . The upper rising portion 72 rises from the rail portion 60 at a rising angle θ1, and a flat (non-curved surface) abutting surface portion 72a that contacts the lower roller portion 52 is provided in the middle. The contact surface portion 72a is linearly inclined to the left side gradually from the upper side to the lower side, and the rotation can be stopped more reliably by the lower roller portion 52 coming into contact therewith. By providing the contact surface portion 72a on the upper rising portion 72 in this way, the resistance when the lower roller portion 52 rotates the restricting portion 70 without causing the restricting portion 70 to protrude extremely greatly with respect to the rail portion 60. It can be. Further, referring to FIG. 12, the lower rising portion 76 is disposed on the lower side facing the lower roller portion 52 when the protector 24 at the original position (retreat limit position) obliquely moves forward and downward in the vehicle. The lower rising portion 76 rises from the rail portion 60 at a rising angle θ2 (θ2 <θ1), and rises more slowly than the upper rising portion 72. The upper bottom portion 74 is a portion that is disposed between the upper rising portion 72 and the lower rising portion 76 and is substantially parallel to the rail portion 60. In the restricting portion 70 of the present embodiment, the portion excluding the contact surface portion 72a is formed in a curved shape, and includes a corner portion R1 from the upper rising portion 72 to the upper bottom portion 74, and a portion from the upper bottom portion 74 to the lower rising portion 76.

[Outline of operation of wheelchair storage device for vehicle]
4 and 5, when the wheelchair K is stored, the protector 24 is obliquely moved forward and downward along the guide portion 22r of the carrier 22 and is disposed at the forward limit position. And after a driver | operator changes to a driver's seat, the hook 31f is hung on the suspension belt Kb of the wheelchair K, and the suspension apparatus 30 is driven. As a result, the wheelchair K is lifted and folded at the same time, and the wheelchair K is set on each restraint plate 24x of the protector 24 from below. When the wheelchair K is thus set on each restraint plate 24x of the protector 24, the protector 24 is lifted by the belt 31 together with the wheelchair K with reference to FIG. Thus, the protector 24 is obliquely moved rearward and upward along the guide portion 22r of the carrier 22 and is disposed at the original position (retreat limit position).

  Here, referring to FIG. 7, the belt 31 is not moved relative to the rear shaft body 43 of the adjuster member 40 until the wheelchair K is set on each restraint plate 24x after the lifting of the wheelchair K is started. The belt 31 slides in the longitudinal direction of the belt 31. At this time, if the suspension position Mr of the wheelchair K is displaced in the vehicle width direction (rightward) with respect to the winding center Mo of the drum 33, the belt 31 is inclined with respect to the rear shaft body 43 of the adjuster member 40. It can be hung on the tip side. Thus, referring to FIG. 8, the pressing force F applied from the belt 31 to the rear shaft body 43 includes a force Fs perpendicular to the inclined portion of the rear shaft body 43 and a force Fb along the inclined portion of the rear shaft body 43. And decomposed. The belt 31 moves (slides) in the direction of the winding center Mo of the drum 33 along the inclined portion of the rear shaft body 43 by the force Fb along the inclined portion of the rear shaft body 43. This makes it difficult for the belt 31 to rub against the winding guide of the drum 33 or the bracket or the like in the process of lifting the wheelchair K.

  In the conventional configuration, excessive friction may occur between the adjuster member 40 (rear shaft body 43) and the belt 31. For this reason, when the wheelchair K is lifted, the belt 31 is locked by the frictional force generated between the adjuster member 40 and the protector 24 is lifted upward prior to the locking with the wheelchair K. There was a risk of being. Therefore, in this embodiment, when the protector 24 moves obliquely with respect to the carrier 22, the rail portion 60 is configured to rotate while being pressed against the lower roller portion 52. Therefore, during the period from when the wheelchair K is lifted to the rail portion 60 and locked to the protector 24, the lower roller portion 52 rotates with respect to the rail portion 60 to restrict the diagonal movement of the protector 24. The regulation part 70 is provided.

  10 and 13, until the wheelchair K is locked to the protector 24, the upper rising portion 72 (contact surface portion 72a) becomes a resistance and the lower roller portion 52 cannot rotate. Retained there. The rising angle θ1 of the upper rising portion 72 is larger than the rising angle θ2 of the lower rising portion 76, and the resistance when the lower roller portion 52 rotates is relatively increased. When the lower roller portion 52 is pressed against the upper rising portion 72, a force (Fc) that presses the upper rising portion 72 downward is generated. For this reason, in a state where the lower roller portion 52 is held by the upper rising portion 72, the downward pressing force (Fc) is combined with the weight of the protector 24 and becomes larger than the frictional force between the adjuster member 40 and the belt 31. For this reason, by the time the wheelchair K is lifted and locked to the protector 24, the lower roller portion 52 is held by the restricting portion 70, whereby the oblique movement of the protector 24 is restricted. For this reason, even if friction occurs between the adjuster member 40 and the belt 31, the movement of the protector 24 itself is restricted, so that the belt 31 moves relative to the adjuster member 40 against the frictional force. The wheelchair K will be lifted up.

  Referring to FIG. 11, after the wheelchair K is set on the restraining plate 24x of the protector 24, the protector 24 is lifted together with the wheelchair K, and the lower roller portion 52 gets over the restricting portion 70 by the lifting force. Can do. Then, referring to FIG. 6, when protector 24 is raised to the upper limit position of carrier 22, protector 24 is held at the same position in the vehicle longitudinal direction with respect to carrier 22, and suspension device 30 stops. Next, the carrier 22 rotates upward to be in a horizontal state, and at the same time, the carrier 22 is placed on the movable frame 15 with the protector 24 and the wheelchair K being lifted up. Then, the movable base 15 slides to the left, and the storage of the wheelchair K is completed in a state where the movable base 15 is held at the storage position on the fixed base 12 as shown in FIG.

  By the way, referring to FIG. 12, even when the protector 24 is obliquely moved from the original position (retreat limit position) to the advance limit position, there is a concern that the restrictor 70 may restrict the oblique movement of the protector 24. The When the protector 24 at the reverse limit position moves obliquely forward and downward of the vehicle, the lower roller portion 52 contacts the lower rising portion 76. Therefore, in this embodiment, the rising angle θ2 of the lower rising portion 76 is reduced, and the resistance when the lower roller portion 52 rotates is relatively reduced. Then, the lower rising portion 76 is pressed against the lower roller portion 52 by the dead weight of the protector 24, so that a force (Fd) applied to the right side is generated. When the protector 24 is obliquely moved forward and downward in the vehicle, it is possible to get over it while pushing the restricting portion 70 by force with the force (Fd) applied to the right. In particular, in this embodiment, the lower roller portion 52 can smoothly pass the corner portions R1 and R2 (curved surface) of the restricting portion 70 and get over the restricting portion 70, and the lower roller portion 52 rides on the restricting portion 70. The looseness at the time can be suitably suppressed.

  As described above, in this embodiment, the diagonal movement of the protector 24 is restricted by the restricting portion 70 until the wheelchair K is locked to the protector 24. Therefore, according to the present embodiment, it is possible to avoid the protector 24 from being lifted prior to the locking with the wheelchair K as much as possible while eliminating the positional deviation between the winding center of the belt 31 and the hanging position of the wheelchair K. Can do. Further, in the present embodiment, by providing a difference in the resistance force of the restricting portion 70, the protector 24 is prevented from being lifted prior to the locking with the wheelchair K as much as possible, and further, the front of the vehicle with respect to the carrier 22. And it can move diagonally smoothly downward. And according to the structure of a present Example, the robustness of the storing operation (well carry operation) of a wheelchair can be improved.

  Further, in the present embodiment, it is possible to avoid the protector 24 from being lifted prior to locking with the wheelchair K as much as possible by the restricting portion 70 having a relatively simple structure. At this time, the rising angle θ1 of the upper rising portion 72 is set larger than the rising angle θ2 of the lower rising portion 76. For this reason, in the present embodiment, the protector 24 is prevented from being lifted prior to locking with the wheelchair K by the restricting portion 70 having a relatively simple configuration, and further forward and downward of the vehicle with respect to the carrier 22. Can move smoothly and diagonally. In this embodiment, the rotation of the lower roller portion 52 is stopped and held by the contact surface portion 72a of the restricting portion 70. For this reason, even if it is set as the structure which makes the control part 70 protrude moderately, the protector 24 can be lifted prior to latching with the wheelchair K by hold | maintaining the lower roller part 52 more reliably by the contact surface part 72a. Can be avoided more reliably. In addition, since the corners R1 and R2 of the protruding portion excluding the contact surface portion 72a are curved, the protector 24 can be smoothly and obliquely moved relative to the carrier 22 forward and downward of the vehicle.

  The vehicle wheelchair storage device of the present embodiment is not limited to the above-described embodiment, and can take other various embodiments. For example, in the present embodiment, the restricting portion 70 as the protruding portion is illustrated, but the configuration (shape, dimension, forming position, etc.) of the restricting portion is not limited. For example, a polygonal restriction part such as a triangular shape, a semicircular or semi-elliptical restriction part, or a step-like restriction part can be formed on the rail part. In addition to the case where the rail portion itself is bent and deformed, the restricting portion can be formed by adding a member different from the rail portion. For example, a projecting piece attached to the rail portion so as to be capable of advancing and retracting (or being able to tilt) can be used as the restricting portion. Further, the restricting portion may be configured to restrict the oblique movement of the protector as a resistance when the roller portion rotates by using a frictional force or a magnetic force. Further, the configuration (shape, dimensions, arrangement position, number of arrangements, etc.) of the rail portion 60 can be appropriately changed according to the apparatus configuration.

  In the present embodiment, an example in which a difference is provided in the resistance force between the upper rising portion and the lower rising portion has been described. On the other hand, if the protector does not extremely inhibit the oblique movement of the protector forward and downward with respect to the carrier, there is no need to provide a difference in the resistance force between the upper rising portion and the lower rising portion. Further, at least one corner of the restricting portion can be rounded, and the restricting portion can be entirely curved, or can be configured not to be curved.

  In this embodiment, the fixed gantry 12, the movable gantry 15, the carrier 22, the protector 24, the suspension device 30, the adjuster member 40, and the various mechanisms WS, RM, and TU are exemplified. As long as a desired function is exhibited, it can be appropriately changed.
