Description

  The present invention includes a body side member connected to a vehicle body, a vertical rotation member connected to the body side member so as to be rotatable between a standing position and a lying position, and the body side member The present invention relates to a vehicular accessory provided with a spring material provided between rotating members and generating a spring force in an upward rotation direction when the vertical rotation member rotates downward from an upright position toward a lying position.

  A technique related to this vehicular accessory is described in Patent Document 1. The vehicular auxiliary device described in Patent Literature 1 is a slope device that allows passengers or the like who use wheelchairs to get on and off the vehicle. The slope device is composed of a body side member (tail gate portion) connected to a lower side position of the rear opening of the vehicle body in a vertically rotatable state, and a slope plate supported by the tail gate portion. Yes. Then, the tailgate portion and the slope plate rotate rearward, so that the slope plate is spanned between the rear opening of the vehicle and the ground, and it is possible to get on and off a wheelchair or the like. Further, as shown in FIG. 20, the slope device 100 is stored inside the rear opening of the vehicle by the tail gate portion 101 and the slope plate 103 rotating upward to the standing position.

  The slope plate 103 is configured to be able to rotate downward from the standing position to the front lying position with respect to the standing tailgate portion 101. In addition, a coil spring 105 that generates a spring force in the upward rotation direction when the slope plate 103 rotates downward with respect to the tail gate portion 101 is mounted at the rotation center position of the slope plate 103. As a result, the slope plate 103, which is relatively heavy, slowly rotates downward to the lying position against the spring force of the coil spring 105. Further, the slope plate 103 in the lying position can be returned to the standing position with a relatively small force by the action of the coil spring 105.

Japanese Patent Laying-Open No. 2015-3714

  The slope device 100 described above is configured such that the spring force of the coil spring 105 is applied in the upward rotation direction when the slope plate 103 rotates downward to the lying down position. For this reason, when the slope plate 103 is in the standing position, the spring force of the coil spring 105 is not generated, and a gap is generally formed between the end of the coil spring 105 and the spring receiving portion such as the slope plate 103. ing. However, if the gap size varies due to the manufacturing accuracy of the coil spring 105, no spring force is generated at the same timing when the slope plate 103 rotates downward.

  For example, when the coil spring 105 that increases the gap size is used, the timing at which the spring force is generated when the slope plate 103 rotates downward is delayed. For this reason, the rotation speed when the slope plate 103 rotates downward is increased, and the specification cannot be satisfied. Therefore, the coil spring 105 having the gap size larger than the standard cannot be used. That is, in the slope device 100 described above, since only the coil spring 105 in which the gap size is within an appropriate range can be used, the yield of the coil spring 105 is deteriorated.

  The present invention has been made to solve the above-mentioned problems, and the problem to be solved by the present invention is to reduce the amount of unusable spring materials by using a structure in which the timing at which the spring force is applied does not vary.

The insertion member can be fixed to the spring receiving portion. Thus, since the insertion member is attached to the spring receiving portion in a removable state, the insertion member can be omitted when the gap between the end of the spring material and the spring receiving portion is small. Further, since the insertion member can be fixed to the spring receiving portion in a state where the insertion member is inserted into the gap, the insertion member does not come out of the gap.

  According to the invention of claim 5, the spring material is a coil spring mounted around the rotation center axis of the vertical rotation member, and is configured to be twisted around the axis as the vertical rotation member rotates. Has been.

  According to the invention of claim 6, the body side member is configured to be vertically rotatable between a standing position where the body side member stands with respect to the vehicle body and a lying position where the body side member falls backward with respect to the vehicle body. The rotating member is configured to be able to rotate up and down between the standing position and a lying position where it lies forward with respect to the body side member in the standing position, and the vertical rotating member in the standing position is also in the standing position. And the body side member lying on the rear side with respect to the body of the vehicle, the vertical rotation member and the body side member can be used as a slope of the vehicle.

  According to the invention of claim 7, the spring receiving portion is a long hole through which an end portion of the spring material is inserted, and the end portion of the spring material is directly or indirectly at the end edge portion in the longitudinal direction of the long hole. The spring member is capable of generating a spring force, and the insertion member is in a state where the spring member does not generate a spring force, and the end of the spring member and the length of the elongated hole are It is comprised so that it may fit in the clearance gap between the edge parts in a direction. For this reason, the clearance gap between the edge part of a spring material and a spring receiving part is filled with an insertion member. Accordingly, the spring force is generated at the same timing when the vertical rotation member rotates downward from the standing position toward the lying position.

  According to invention of Claim 8, the insertion member is comprised so that the peripheral part of the said long hole may be pinched | interposed from the front and back in the state fitted by the inner side of the long hole. For this reason, it becomes difficult for the said insertion member to remove | deviate from the long hole of a spring receiving part.

  According to the invention of claim 9, the plurality of insertion members are formed to have the same shape and the same thickness, and the end portions of the spring material and the length of the plurality of insertion members are stacked in the thickness direction. It is comprised so that it may fit in the clearance gap between the edge parts in the longitudinal direction of a hole. For this reason, even if the size of the gap between the end portion of the spring material and the end edge portion in the longitudinal direction of the elongated hole is various, a single type of insertion member can be used.

  According to the present invention, there is no variation in the timing at which the spring force works, the number of unusable spring materials is reduced, and the yield of spring materials is improved.

Between the tailgate 30 and the vehicle C, as shown in FIG. The backward tilting lock device 40 is a device that locks the tailgate 30 in the upright position, and includes a lock mechanism 45 and a body side striker 43. The lock mechanism 45 is fixed to an outer position in the vehicle width direction of the cam plate 32 of the tailgate portion 30 as shown in FIGS. As shown in FIG. 4, the body side striker 43 is attached to the left and right sides of the rear opening H of the vehicle C. Then, as shown in FIG. 6, in a state where the tailgate portion 30 is rotated upward to the standing position, the lock mechanism 45 of the tailgate portion 30 is engaged with the body-side striker 43 of the vehicle C, and the tailgate is engaged. The portion 30 is held in the standing position (the body side striker 43 is omitted in FIG. 6). Note that when the lock mechanism 45 is unlocked by a lock release device (not shown), the tailgate 30 can fall backward as shown in FIGS. 4 and 5. That is, the tailgate portion 30 corresponds to the body side member of the present invention.

<Forward hinge mechanism 35>
As shown in FIG. 9 and the like, the forward tilting hinge mechanism 35 is a mechanism that connects the left and right slope plate mounting brackets 37 of the slope plate main body 20 and the left and right upper portions of the tailgate portion 30.

The cylindrical body 373 is fixed to the side wall surface of the slope plate mounting bracket 37 at a right angle and is formed so as to protrude inward in the vehicle width direction. The distal end portion of the cylindrical body 373 of the slope plate mounting bracket 37 is rotatably supported by a bearing portion 344 fixed to the cross beam portion 34 of the tailgate portion 30. As a result, the slope plate mounting bracket 37 (slope plate main body portion 20) can be tilted forward with respect to the tailgate portion 30 and can be turned up and down around the hinge shaft (support shaft 321) of the hinge mechanism 35.

<About the lock mechanism 50 for forward regulation>
The forward tilt restricting lock mechanism 50 is a mechanism that restricts (inhibits) the rotation of the slope plate main body portion 20 in the standing position with respect to the tailgate portion 30 in the standing position. As shown in FIGS. 7 and 8, the forward-restricting lock mechanism 50 is provided on the outer periphery of the lever member 52 connected to the slope plate mounting bracket 37 of the slope plate body 20 and the cam plate 32 of the tailgate portion 30. And a cam surface 54 formed. The central portion of the lever member 52 is connected to the slope plate mounting bracket 37 so as to be rotatable by the connecting pin 51. A lock pin 521 configured to be slidable along the cam surface 54 of the cam plate 32 of the tailgate portion 30 is provided below the lever member 52. A lock spring 57 that is biased so as to press the lock pin 521 of the lever member 52 against the cam surface 54 of the cam plate 32 is connected to the upper portion of the lever member 52.

  An upper lock groove 541 in which the lock pin 521 of the lever member 52 is fitted is formed on the cam surface 54 of the cam plate 32 of the tailgate portion 30 at the upper end position of the cam surface 54. Then, the slope plate body 20 rotates upward (stands up) from the forward lying position to the standing position with respect to the tailgate portion 30 in the standing position, so that the lock pin 521 of the lever member 52 has the spring force of the lock spring 57. Thus, the upper locking groove 541 of the cam surface 54 is engaged. As a result, the forward tilt restricting lock mechanism 50 is locked, and the slope plate body 20 is held in the upright position. By rotating the lever member 52 to the right against the spring force of the lock spring 57, the lock pin 521 of the lever member 52 is disengaged from the upper lock groove 541 of the cam surface 54, and the lock mechanism 50 for locking the forward movement restricting mechanism 50 is locked. The state is released. As a result, the slope plate body 20 can be turned downward (forward) with respect to the tailgate 30. That is, the slope plate main body 20 corresponds to the up and down rotation member of the present invention.

<For forward shock absorbing spring mechanism 60>
As shown in FIGS. 9 to 13, the slope plate main body portion with respect to the tail gate portion 30 is released between the slope plate main body portion 20 and the tail gate portion 30 in a state where the locked state of the forward-restriction regulating lock mechanism 50 is released. A forward shock-absorbing spring mechanism 60 is provided so that it can be gently rotated downward (forward) 20 forward. As shown in FIG. 9 and the like, the forward shock absorbing spring mechanism 60 includes a coil spring 63 provided between the slope plate main body 20 and the tail gate portion 30, an end 63f of the coil spring 63, and the tail gate portion 30 (transverse beam). The insertion member 65 is inserted into the gap S between the spring receiving portions 34b of the portion 34).

  The coil spring 63 is provided so as to surround the cylindrical body 373 of the slope plate mounting bracket 37 of the slope plate main body portion 20, and one end portion 63e of the coil spring 63 is, as shown in FIG. The spring receiving hole 37a is inserted. For this reason, as shown in FIGS. 12 and 13, the one end portion 63 e of the coil spring 63 rotates left together with the slope plate main body 20 when the slope plate main body 20 rotates downward (rotates left). It becomes like this. Further, the other end portion 63 f of the coil spring 63 is configured to be received by a spring receiving portion 34 b provided on the cross beam portion 34 of the tailgate portion 30. Further, the other end portion 63f of the coil spring 63 is pressed from the opposite side of the spring receiving portion 34b by a presser 344p provided on the bearing portion 344 of the forward-turning hinge mechanism 35, as shown in FIG.

  When the slope plate main body 20 is rotated downward (left-turned) forward from the standing position, the coil spring 63 is rotated about the axis by rotating one end 63e of the coil spring 63 together with the slope plate main body 20 to the left. Twist and spring force is generated in the upward rotation direction (right rotation direction). For this reason, in a state where the slope plate main body 20 is in the standing position, the coil spring 63 is not twisted around the axis and does not generate a spring force. Therefore, in a state where the slope plate main body 20 is in the standing position, generally, the gap between the other end 63f of the coil spring 63 and the spring receiving portion 34b of the tailgate portion 30 (lateral beam portion 34) is as shown in FIG. In addition, a gap S is formed.

  The dimension of the gap S changes due to variations in the manufacturing accuracy of the coil spring 63. For example, when the coil spring 63 having a large gap dimension is used, the timing at which the spring force is generated is delayed when the slope plate main body 20 rotates downward (rotates left) forward. For this reason, the rotation speed when the slope plate main body 20 rotates downward (rotates left) forward is increased. In order to prevent this, in the forward shock absorbing spring mechanism 60, the insertion member 65 is inserted into the gap S between the other end portion 63f of the coil spring 63 and the spring receiving portion 34b of the tailgate portion 30 (lateral beam portion 34), The gap S is filled.

  As shown in FIGS. 9 to 11, the insertion member 65 is formed in a substantially fan-shaped plate shape, and the tailgate portion 30 (horizontal beam portion) in a state in which a main portion of the fan can be rotated by a connecting bolt 65 p. 34) and the spring receiving portion 34b. Then, the insertion member 65 rotates about the connecting bolt 65p, so that the substantially arc-shaped end edge of the insertion member 65 becomes the other end portion 63f of the coil spring 63 and the spring support of the tailgate portion 30 (lateral beam portion 34). It is inserted into the gap S between the portions 34b. At the substantially arc-shaped end edge of the insertion member 65, there are a first insertion portion 65a equal to the plate thickness, a second projection portion 65b having a low projection, and a third insertion portion 65c having a relatively high projection. Are formed side by side in the circumferential direction.

  Therefore, according to the dimension of the gap S between the other end portion 63f of the coil spring 63 and the spring receiving portion 34b of the tailgate portion 30 (lateral beam portion 34), as shown in FIGS. The first insertion portion 65a, the second insertion portion 65b, or the third insertion portion 65c can be inserted into the gap S. And after inserting the insertion member 65 in the said clearance gap S, the insertion member 65 is fixed to the spring receiving part 34b of the tail gate part 30 (lateral beam part 34) by the rivet 65w. If the dimension of the gap S is smaller than the thickness of the insertion member 65, the connecting bolt 65p is removed and the insertion member 65 is removed from the spring receiving portion 34b of the tailgate portion 30 (lateral beam portion 34). Can do.

<Handling of the slope device 10>
In a state where the slope device 10 is stored in the vehicle C, as shown in FIGS. 6 and 7, the slope plate main body portion 20 and the tailgate portion 30 are both in the standing position, The forward-restricting lock mechanism 50 is held in a locked state. When the occupant is to be on the wheelchair from this state, the locked state of the backward fall restricting lock device 40 is released, and the slope plate main body portion 20 and the tailgate portion 30 are integrated into the rear as shown in FIG. The tilting hinge mechanism 31 is rotated backward to the deployment position around the rotation center. And as shown in FIG. 2, the 1st flat plate part 21 is pulled out from the 2nd storage board part 22 of the slope board main-body part 20, and the slope board main-body part 20 is provided between the rear side opening part H of the vehicle C, and the ground. It is possible to ride the wheelchair passenger from the rear opening H by using the slope plate main body portion 20.

  Further, as shown in FIG. 6, when loading a load on the vehicle C from a state in which the slope plate body 20 and the tailgate 30 are in the standing position, the left and right lever members 52 are operated to move the left and right forwards. The locked state of the restriction lock mechanism 50 is released. As a result, the slope plate main body portion 20 can be turned downward forward with respect to the tailgate portion 30 in the standing position. At this time, the slope plate main body portion 20 is gently tilted forward because it rotates downwardly against the spring force of the coil spring 63 of the forward shock absorbing spring mechanism 60.

  Further, since the gap S between the other end portion 63f of the coil spring 63 and the spring receiving portion 34b of the tail gate portion 30 (the horizontal beam portion 34) is filled with the insertion member 65, the slope plate main body portion 20 rotates downwardly forward. The spring force is always generated at the same timing. For this reason, the rotational speed when the slope plate main body 20 is moved forward can always be made constant. Then, a load can be loaded on the slope plate main body 20 with the slope plate main body 20 lying on the floor surface. Further, when the slope plate body 20 is turned upward in the standing position direction, the spring force of the coil spring 63 can be used, so that the slope plate body 20 can be turned upward with a relatively small force.

<Advantages of the slope device 10 according to this embodiment>
According to the slope device 10 according to the present embodiment, the insertion member 65 is the end of the coil spring 63 in a state where the slope plate body 20 (vertical rotating member) is in the upright position and the coil spring 63 does not generate a spring force. It is inserted into the gap S between 63f and the spring receiving portion 34b. In other words, the insertion member 65 fills the gap S between the end 63f of the coil spring 63 and the spring receiving portion 34b. For this reason, when the slope plate body 20 is rotated downward from the standing position toward the lying position, the spring force of the coil spring 63 is generated at the same timing, and the slope plate body 20 is rotated downward to the lying position at the same speed. become. Thus, since the gap S is not generated between the end portion 63f of the coil spring 63 and the spring receiving portion 34b by using the insertion member 65, the coil spring 63 that cannot be used due to the size of the gap is eliminated, and the coil spring 63 is removed. The yield is improved.

  The insertion member 65 is formed with a plurality of first insertion portions 65a, second insertion portions 65b, and third insertion portions 65c, which are a plurality of protrusions having different height dimensions. The coil spring 63 can be dealt with. Further, the insertion member 65 is attached to the spring receiving portion 34b in a rotatable state, and a plurality of protrusions (first insertion portion 65a, second insertion portion 65b) are formed on the arc-shaped end edge portion of the insertion member 65. The third insertion portion 65c) is formed side by side in the circumferential direction. For this reason, the insertion member 65 including a plurality of protrusions can be compactly formed. Furthermore, any one of the first insertion portion 65a, the second insertion portion 65b, and the third insertion portion 65c can be inserted into the gap S in a state where the insertion member 65 is connected to the spring receiving portion 34b. Further, since the insertion member 65 is attached to the spring receiving portion 34b in a removable state, the insertion member 65 can be removed if the gap dimension between the end 63f of the coil spring 63 and the spring receiving portion 34b is small. it can. Furthermore, since the insertion member 65 can be fixed to the spring receiving portion 34b in a state where the insertion member 65 is inserted into the gap S, the insertion member 65 does not come out of the gap S.

<Example of change>
Here, the present invention is not limited to the above-described embodiment, and can be modified without departing from the gist of the present invention. For example, in the present embodiment, an example in which the coil spring 63 is used as the spring material of the forward shock absorbing spring mechanism 60 has been shown. However, for example, a plate spring or the like can be used instead of the coil spring 63.

The width dimension of the square groove 72m of the insertion member 72, that is, the gap dimension between the left and right square protrusions 72t is set to a value substantially equal to the plate thickness dimension of the peripheral edge of the spring receiving long hole 37a. The distance between the upper rectangular groove 72m and the lower rectangular groove 72m of the insertion member 72 is set to a value substantially equal to the width dimension of the spring receiving elongated hole 37a. Furthermore, the thickness dimension of the insertion member 72 is set to about 1/3 of the diameter dimension of the wire in the coil spring 63 as shown in FIG.

<About the attachment procedure of the insertion member 72>
Next, a procedure for attaching the insertion member 72 will be described. Here, a plurality of insertion members 72 (four in FIG. 14) are used as one set. First, as shown in FIG. 16, in the state where the slope plate main body portion 20 is in the standing position and the spring force of the coil spring 63 is not generated, the other end portion 63f of the coil spring 63 is connected to the tailgate portion 30 (lateral beam portion 34). It is made to contact | abut to the spring receiver 34b. In this state, the state of the gap S between the one end portion 63e of the coil spring 63 and the end edge portion in the longitudinal direction of the spring receiving long hole 37a of the slope plate mounting bracket 37 is confirmed. That is, the number of the insertion members 72 set before and after the one end portion 63e of the coil spring 63 is confirmed from the front gap S and the rear gap S of the one end portion 63e of the coil spring 63. Next, with the one end 63e of the coil spring 63 removed from the spring receiving long hole 37a of the slope plate mounting bracket 37, the insertion member 72 is set in the spring receiving long hole 37a.

  That is, by inserting the insertion member 72 into the spring receiving long hole 37a in an oblique state and raising the insertion member 72, the upper rectangular groove 72m and the lower rectangular groove 72m of the insertion member 72 are spring-loaded. It is made to fit in the peripheral part of the hole 37a. Thereby, as shown in FIG. 15, the left and right rectangular protrusions 72t of the insertion member 72 sandwich the peripheral edge of the spring receiving long hole 37a from the front and back, and the insertion member 72 is set in the spring receiving long hole 37a. . In this way, as shown in FIG. 14, in the state where two insertion members 72 are set before and after the spring receiving long hole 37a, one end 63e of the coil spring 63 is inserted into the spring receiving long hole 37a.

As a result, the insertion member 72 fills the gap S between the one end portion 63 e of the coil spring 63 and the edge of the spring receiving long hole 37 a of the slope plate mounting bracket 37.

<Advantages of the slope device according to this embodiment>
According to the slope device according to the present embodiment, the insertion member 72 fills the gap S between the one end portion 63 e of the coil spring 63 and the end edge portion in the longitudinal direction of the spring receiving long hole 37 a of the slope plate mounting bracket 37. For this reason, when the slope plate main body 20 is tilted forward from the standing position, the spring force of the coil spring 63 is generated at the same timing, and the slope plate main body 20 is rotated downward to the fall position at the same speed. Further, the insertion member 72 is configured to sandwich the peripheral edge of the spring receiving long hole 37a from the front and back sides in a state of being fitted inside the spring receiving long hole 37a. For this reason, it becomes difficult for the said insertion member 72 to remove | deviate from the said spring receiving long hole 37a. In addition, the plurality of insertion members 72 are formed in the same shape and the same thickness dimension, and the longitudinal direction of the one end portion 63e of the coil spring 63 and the spring receiving long hole 37a in a state where the plurality of insertion members 72 are stacked in the thickness direction. Is fitted between the end edges. For this reason, even if the size of the gap S between the one end portion 63e of the coil spring 63 and the end edge portion in the longitudinal direction of the spring receiving long hole 37a varies, it is possible to cope with one type of insertion member 72.
