Since the handrail supports the user, high strength is required.
In this respect, the handrail of Patent Document 1 is a structure in which only one end is supported by a support wall, that is, a so-called cantilever structure, and thus acts on the hinge when the user grabs the handrail body and a load is applied. The force tends to increase and it is difficult to secure the required strength.

  And as the protrusion amount of the handrail main body from the support wall increases, the force acting on the handrail portion and the hinge increases, so that the strength required for the handrail portion and hinge increases. For this reason, it is extremely difficult to secure the necessary strength with a handrail that is desired to increase the amount of protrusion from the support wall.

  This invention is made | formed in view of such a situation, The objective is to provide the handrail which can ensure required intensity | strength easily.

  A handrail for solving the above-mentioned problem is a main body support portion fixed to a support body, has a rod shape, and a base end is tiltably connected to the main body support portion via a first hinge portion, and its tilt position A handrail main body that can be switched between a position extending along the main body support section and a position raised with respect to the main body support section, and a position at which the main body support section is fixed on the support body. A support support portion fixed at a fixed position, and a shape connecting the support support portion with a portion of the handrail main body that is more distal than the base end, and provided at an intermediate portion in the extending direction. A structure that can be bent and extended via a second hinge part, and a portion closer to the handrail body than the second hinge part is tiltably connected to the handrail body via a third hinge part; A support portion in which a portion closer to the support support portion than the two hinge portions is connected to the support support portion via a fourth hinge portion so as to be tiltable; and the support portion is connected to the support body and the handrail body. And a lock portion that locks in a state of being stretched between.

  According to the above configuration, when the handrail is not used, the support portion is tilted between the handrail body and the support body (specifically, the support support portion) so that the tilt position of the handrail body is supported by the support body. It can be a position (storage position) extending along the line. Thereby, the handrail main body can be brought down so as not to get in the way. Moreover, when using the handrail, the support portion is extended between the handrail body and the support body, so that the tilting position of the handrail body is raised to the support body (deployment position). it can.

The second support portion 71 tilts in the vertical direction about the tilt center L4 of the fourth hinge portion through the engaging portion of the 71 with the long hole portion 78.

  When the pin engagement hole 54 of the support support portion 50 and the lock hole 121 of the second support portion 71 overlap with each other due to the tilting of the second support portion 71 (the state shown in FIG. 5), the first engagement is achieved. The mating pin 113 is moved by the urging force of the coil spring 59 and inserted into the lock hole 121. As a result, the first support pin 113 is inserted into the pin engagement hole 54 of the support support portion 50 and the lock hole 121 of the second support portion 71 as shown in FIG. The relative tilting between the second support portion 71 and the support support portion 50 is restricted when the portion 71 is raised with respect to the support support portion 50. At this time, as shown in FIG. 1B, the support portion 60 is locked in a state of extending between the support support portion 50 and the handrail body 20. The lock portion 120 (FIG. 7) includes a first engagement pin 113, a pin engagement hole 54 of the support support portion 50, a bracket 55 (FIG. 4), a coil spring 59, and a lock hole 121 of the second support portion 71. It is constituted by.

  As shown in FIG. 1B, when the handrail is used, the support portion 60 is extended between the handrail body 20 and the vehicle support wall 15 (specifically, the support support portion 50). Accordingly, the tilt position of the handrail body 20 can be set to the position where the handrail body 20 is raised with respect to the support wall 15 (the development position). In this state, by locking the tilting operation of the second support portion 71 with respect to the support support portion 50 by the lock portion 120 (see FIG. 7), the base end of the handrail body 20 is supported by the support wall 15. Thus, a portion (inclined portion 21) to which the support portion 60 is connected in the handrail main body 20 is also supported by the support wall 15. Therefore, compared to the structure in which only the base end of the handrail body 20 is supported by the support wall 15, the strength against the load when the handrail body 20 is used can be increased, and the necessary strength can be easily ensured. Can do.

  In FIG. 1A and FIG. 1B, the tilt center of the second hinge portion 80 (the tilt center of the bending operation of the support portion 60) is indicated by “L2”. Further, the tilt center of the third hinge portion 90 (the tilt center of the first support portion 61 with respect to the handrail body 20) is indicated by “L3”, and the tilt center of the fourth hinge portion 100 (the support support portion 50 of the second support portion 71). The center of tilting with respect to is indicated by “L4”.

  As is clear from FIGS. 1A and 1B, in this embodiment, the tilting position of the handrail body 20 is changed from the retracted position (position shown in FIG. 1A) to the deployed position (FIG. 1B). 2), the tilt center L2 of the second hinge part 80 moves so as to straddle the straight line connecting the tilt center L3 of the third hinge part 90 and the tilt center L4 of the fourth hinge part 100. Structure. Specifically, as shown in FIG. 1A, when the tilting position of the handrail body 20 is the storage position, the support portion 60 is bent in such a manner that it protrudes upward. On the other hand, as shown in FIG. 1B, when the tilting position of the handrail body 20 is the deployed position, the support portion 60 is bent slightly in a convex shape toward the lower side.

  As described above, in the present embodiment, the direction in which the support portion 60 bends is different when the handrail body 20 is tilted at the retracted position and at the deployed position. Therefore, when the user grips the handrail body 20 and puts weight on the handrail body 20 in the state where the handrail body 20 is tilted, the load is bent when the handrail body 20 is tilted toward the storage position. The support portion 60 is bent in the opposite direction. Therefore, the handrail can be structured to prevent the handrail main body 20 from being unnecessarily tilted toward the storage position.

  In the present embodiment, when the tilt angle of the handrail body 20 is increased without operating the lock portion 120 (FIG. 7), the first wall 61 in the ceiling wall portion 62 of the skeleton portion 64 (FIG. 4) of the first support portion 61. The end portion on the second hinge portion 80 side and the portion on the second hinge portion 80 side in the ceiling wall portion 72 of the second support portion 71 abut against each other, and the support portion 60 is restricted from further bending. For this reason, even if the lock unit 120 does not operate, it is possible to suppress a situation in which the handrail body 20 falls down unnecessarily.

  Further, in the present embodiment, as shown in FIG. 1B, when the tilting position of the handrail main body 20 becomes the unfolded position, the horizontal portion 22 formed at the distal end portion and the proximal end portion of the handrail main body 20 is horizontally aligned. It will be in an extended state. Therefore, the handrail main body 20 has a shape that is easy for the user to hold and that the user can easily put on the weight when supporting the body.

  In addition, the inclined portion 21 formed in the intermediate portion of the handrail main body 20 is inclined and extends so as to be positioned at the lower side toward the tip, and below the inclined portion 21 and the main body support portion 40. A support portion 60 is installed between the support support portion 50 and the support support portion 50. Therefore, although the handrail body 20 includes the horizontal portion 22, the angle between the support portion 60 and the support portion 60 of the handrail body 20 and the support portion 60 is the same as the entire handrail body. The angle can be close to a right angle as compared with the case of the portion. Therefore, the handrail main body 20 and the support portion 60 can be connected in a manner in which a load acting on the support portion 60 from the handrail main body 20 during use can be easily received by the support portion 60.

  On the other hand, when the first engagement pin 113 is in the unlocked state as described above, the second support portion 71 tilts and the pin engagement hole 54 of the support support portion 50 and the fixing hole of the second support portion 71 are fixed. When the state overlaps 131 (the state shown in FIG. 8), the first engagement pin 113 is moved by the biasing force of the coil spring 59 and inserted into the fixing hole 131.

  As a result, the first engagement pin 113 is inserted into the pin engagement hole 54 of the support support portion 50 and the fixing hole 131 of the second support portion 71, so that the second support portion 71 is supported by the support support portion 50. The relative tilt between the second support portion 71 and the support support portion 50 is restricted in a state extending along the direction. At this time, as shown in FIG. 1A, the support portion 60 is fixed in a bent state between the support support portion 50 and the handrail body 20. The fixing portion 130 (FIG. 8) includes the first engaging pin 113, the pin engaging hole 54 of the support support portion 50, the bracket 55 (FIG. 4), the coil spring 59, and the fixing hole 131 of the second support portion 71. It is constituted by.

  As shown in FIG. 1A, when the handrail is not used, the support portion 60 is bent between the handrail main body 20 and the support wall 15 so that the tilt position of the handrail main body 20 is set to the support wall 15. It can be a storage position extending along. Thereby, the handrail main body 20 can be tilted out of the way and fixed in that state.

  Further, in the present embodiment, the operation unit 110, the lock unit 120 (FIG. 7), and the fixing unit 130 (FIG. 8) are arranged together at the connection portion between the second support unit 71 and the support support unit 50. Compared with the case where the operation unit 110, the lock unit 120, and the fixing unit 130 are arranged in a distributed manner, the space can be used effectively.

  As shown in FIG. 9, a support that biases the first support portion 61 and the handrail main body 20 in a direction in which the first support portion 61 and the handrail main body 20 are tilted relative to each other at the connecting portion (third hinge portion 90) between the first support portion 61 and the handrail main body 20. A coil spring 96 is provided as an urging portion. The coil spring 96 biases the first support portion 61 in a direction in which the support portion 60 is bent when the support portion 60 is locked by the lock portion 120, and brings the tilting position of the handrail body 20 closer to the retracted position. It arrange | positions so that the 1st support part 61 may be urged | biased in the direction (specifically, the direction which makes the 1st support part 61 rotate counterclockwise in FIG. 9 with respect to the handrail main body 20).

  As a result, when the handrail body 20 is moved in the direction of rising relative to the vehicle support wall 15 to use the handrail, the biasing force of the coil spring 96 is applied to the handrail when the tilt position of the handrail body 20 approaches the deployed position. Since the main body 20 acts to suppress the movement of the main body 20 in the rising direction, the handrail main body 20 can be operated smoothly while suppressing a steep operation.

  Moreover, when the lock by the lock part 120 is released by grasping the operation part 110 and pulling it away from the support support part 50, the first support part 61 is slightly tilted by the biasing force of the coil spring 96, and the support part. 60 is bent, and the positions of the pin engagement holes 54 (FIG. 7) of the support support portion 50 and the lock holes 121 of the second support portion 71 are shifted. Therefore, the first engagement pin 113 has come out of the lock hole 121 and hit the outer surface of the second support portion 71, that is, the operation, without pulling the operation portion 110 and rotating the operation portion 110. The unit 110 can be brought into a state where it can be rotated. Thereby, operation which folds a handrail can be performed easily.

  As shown in FIG. 2, a leaf spring 103 as a main body urging portion is attached to the inner surface of the bottom wall portion 51 of the support support portion 50. When the handrail body 20 is fixed by the fixing portion 130 (the state shown in FIGS. 1A and 8), the leaf spring 103 is moved by the second support portion 71 as shown in FIG. They are arranged in such a manner that they are pressed and elastically deformed. A two-dot chain line in FIG. 10 indicates the leaf spring 103 in a free state that is not pressed by the second support portion 71.

  In the present embodiment, in a state where the handrail body 20 is fixed by the fixing portion 130, the second support portion 71 is urged in a direction away from the support support portion 50 by the urging force of the leaf spring 103. Therefore, if the fixing by the fixing portion 130 is released by grasping the operation portion 110 and pulling it away from the support support portion 50 to use the handrail, the second support portion 71 is applied by the urging force of the leaf spring 103. Slightly tilts in a direction away from the bottom wall 51 of the support support 50. Accordingly, the positions of the pin engagement holes 54 (FIG. 8) of the support support portion 50 and the fixing holes 131 of the second support portion 71 are shifted. Accordingly, the first engagement pin 113 has come out of the fixing hole 131 and hits the outer surface of the second support portion 71, that is, the operation, without pulling the operation portion 110 and rotating the operation portion 110. The unit 110 can be brought into a state where it can be rotated. Thereby, it becomes possible to easily perform the operation of bringing the handrail body 20 to the raised position with respect to the support wall 15 of the vehicle.

  Moreover, when the handrail body 20 is tilted so as not to get in the way, the support portion 60 operates so as to bend. However, when the tilting position of the handrail body 20 approaches the storage position, the second direction in the direction approaching the support support portion 50 is obtained. The biasing force of the leaf spring 103 acts so as to suppress the operation of the support portion 71. Thereby, since the steep operation | movement of the 2nd support part 71 and the handrail main body 20 is suppressed, it can suppress that a user pinches a hand in a handrail.

  As shown in FIG. 1A, the first support portion 61 is in a state where the support portion 60 is bent between the handrail main body 20 and the support support portion 50 with the tilting position of the handrail main body 20 being the storage position. And curved in a shape that is convex in a direction away from the second support portion 71. Thereby, a gap that is not lost during the bending and extending operation of the support portion 60 is formed between the first support portion 61 and the second support portion 71. Moreover, at this time, the first support portion 61 extends along a bent portion composed of the horizontal portion 22 and the inclined portion 21 on the proximal end side of the handrail main body 20, so that the first support portion 61 and the handrail main body 20 are extended. A gap that does not disappear during the bending and stretching operation of the support portion 60 is also formed. Therefore, when the handrail main body 20 is tilted out of the way, it is possible to prevent the user from pinching the handrail with the finger.

  Further, as shown in FIGS. 1A and 11, when the tilting position of the handrail main body 20 becomes the storage position and the support portion 60 is bent between the handrail main body 20 and the support support portion 50. The first support portion 61 is in a state of extending obliquely downward so that the lower side portion is positioned away from the support support portion 50. Therefore, the force due to the weight of the first support part 61 acting on the connection part (second hinge part 80) between the first support part 61 and the second support part 71 is a direction in which the connection part is separated from the support support part 50. (Left direction in FIG. 11) is included. Therefore, as indicated by an arrow in FIG. 11, the load due to the weight of the first support portion 61 acts to tilt the second support portion 71 in a direction away from the support support portion 50. In the present embodiment, using this load, the operation when the tilting position of the handrail body 20 is set to the deployed position can be easily performed with a small force.

  As shown in FIG. 12, the operation unit 110 is formed in a plate shape extending in a direction substantially orthogonal to the tilting center L4 of the second support unit 71, and is gripped with a hand H having a standard size. The finger is not formed around the back of the operation unit 110 (specifically, the support support unit 50 side). Specifically, when the operation unit 110 is gripped by a hand H having a standard size, the palm contacts the outer surface of the operation unit 110 that is separated from the support support unit 50, and the outer surface of the operation unit 110 is The size and shape of the operation unit 110 are determined so that the belly of the finger comes into contact. Therefore, when the user grasps the operation unit 110 to tilt the handrail main body 20, the user's finger does not easily turn around to the back side of the operation unit 110, so that the user holds the finger when operating the operation unit 110. Can be suppressed.

As described above, according to the present embodiment, the following effects can be obtained.
(1) Compared to the structure in which only the base end of the handrail body 20 is supported by the support wall 15, the strength against the load during use of the handrail body 20 can be increased, and the necessary strength can be easily secured. be able to. Moreover, when the handrail is not used, the handrail main body 20 can be tilted so as not to get in the way.

  (2) When the tilting position of the handrail body 20 shifts from the retracted position to the deployed position, the tilting center L2 of the second hinge part 80 is the tilting center L3 of the third hinge part 90 and the tilting center of the fourth hinge part 100. It was made the structure which moves so that the straight line which connects L4 might be straddled. For this reason, the handrail can be structured to prevent the handrail main body 20 from being unnecessarily tilted toward the storage position.

(3) The tilting position of the handrail body 20 can be fixed at the retracted position by the fixing portion 130.
(4) When the handrail main body 20 is fixed to the inner surface of the bottom wall portion 51 of the support support portion 50 by the fixing portion 130, the handrail main body 20 is urged in a direction away from the support support portion 50. A spring 103 was provided. Therefore, the operation of bringing the handrail body 20 to the raised position with respect to the support wall 15 of the vehicle can be easily performed. In addition, when the handrail main body 20 is tilted out of the way, the steep operations of the second support portion 71 and the handrail main body 20 can be suppressed, and the user can be prevented from pinching the handrail.

  (5) The first support portion 61 is attached to the connecting portion between the first support portion 61 and the handrail main body 20 in a direction in which the tilt position of the handrail main body 20 is brought closer to the storage position when the support portion 60 is locked by the lock portion 120. The coil spring 96 is disposed so as to be biased and biased in the direction in which the support portion 60 is bent. Therefore, when operating the handrail body 20 in the direction to get up with respect to the support wall 15 of the vehicle to use the handrail, the handrail body 20 can be operated smoothly while suppressing a steep operation. In addition, when releasing the lock by the lock portion 120, the first engagement pin 113 escapes from the lock hole 121 and the second support is performed without pulling the operation portion 110 by simply pulling the operation portion 110. It can be in the state where it hits against the outer surface of the part 71, that is, the state in which the operation part 110 can be rotated, and the operation of folding the handrail can be easily performed.

  (6) The operation part 110 for tilting the second support part 71 with respect to the support support part 50 is attached to the connecting part between the second support part 71 and the support support part 50. Therefore, by operating the operation unit 110 without directly touching the support unit 60, the operation of bending and extending the support unit 60, and thus the operation of tilting the handrail body 20 can be performed. Therefore, it is possible to suppress the user's fingertip from entering the tilting range of the support unit 60 and the tilting range of the handrail main body 20, and it is possible to suppress the user from pinching the finger during the handrail operation.

  (7) The operation unit 110 has a plate shape extending in a direction substantially orthogonal to the tilting center L4 of the second support unit 71, and is positioned on the back side of the operation unit 110 when grasped with a hand H having a standard size. The shape is such that fingers do not go around. Therefore, when the user grasps the operation unit 110 to tilt the handrail main body 20, the user's finger does not easily turn around to the back side of the operation unit 110, so that the user holds the finger when operating the operation unit 110. Can be suppressed.

  (8) Since the operation unit 110, the lock unit 120, and the fixing unit 130 are collectively arranged at the connection portion between the second support unit 71 and the support support unit 50, space can be used effectively.

  (9) When the tilting position of the handrail main body 20 becomes the retracted position and the support portion 60 is bent between the handrail main body 20 and the support support portion 50, it protrudes in a direction away from the second support portion 71. The first support portion 61 extends in a curved shape. Therefore, it is possible to prevent the user from pinching the handrail with the handrail when the handrail body 20 is tilted out of the way.

  (10) The front end portion and the base end portion of the handrail main body 20 are formed into a horizontal portion 22 that extends in the horizontal direction when the tilting position of the handrail main body 20 is the deployed position. Therefore, the handrail main body 20 can be formed into a shape that is easy for the user to grip and easy to put on the weight when the user supports the body. Moreover, the intermediate portion of the handrail main body 20 is formed as an inclined portion 21 that extends so as to be inclined downwardly toward the tip when the tilting position of the handrail main body 20 is the deployed position. Therefore, the handrail main body 20 and the support portion 60 can be connected in a manner in which a load acting on the support portion 60 from the handrail main body 20 during use can be easily received by the support portion 60.

  (11) At the tip of the handrail main body 20, a convex portion 25 having a shape in which a portion that becomes lower when the handrail is used projects downward is formed. For this reason, when the handrail is used, it is possible to intuitively know that it is the tip portion of the handrail body 20 when the user touches the convex portion 25 because the user's hand is caught. The feeling can be improved.

  (12) The tilt position of the handrail main body 20 can be switched between a position extending along the frame of the vehicle entrance / exit 11 (storage position) and a position extending to the outside of the vehicle (deployment position). Therefore, when the handrail is used, since the handrail body 20 is structured to extend to the outside of the vehicle, the amount of protrusion of the handrail body 20 from the support wall 15 is likely to increase, but the handrail strength against the load is increased. The required strength can be easily ensured. Moreover, when the handrail is not used, the handrail main body 20 can be brought down so as not to get in the way and can be extended along the frame of the entrance 11 of the vehicle.

The above embodiment may be modified as follows.
-The shape of the convex part 25 of the cap 24 can be changed arbitrarily. For example, a convex part that protrudes to the side is provided at a part that is lateral to the tip of the cap when the handrail is used, or a convex part that protrudes upward to a part that is above the cap tip when the handrail is used. Can be provided. Moreover, you may make it provide the recessed part of the shape which became partially depressed in the cap outer surface. In short, if a portion having a shape significantly different from other portions is provided at the tip (or the vicinity thereof) of the handrail body, it is intuitive that the handrail body 20 is the tip portion of the handrail body 20 by touching the same portion. Therefore, it is possible to improve the feeling of use of the handrail.

A coil spring may be provided instead of providing the plate spring 103 in the support support portion 50.
-The leaf | plate spring 103 provided in the support support part 50 can be abbreviate | omitted.

  -Instead of providing the coil spring 96 in the third hinge part 90, a leaf spring having a shape extending from the handrail body 20 through the third hinge part 90 to the first support part 61 may be provided.

-The coil spring 96 provided in the 3rd hinge part 90 is omissible.
The arrangement position of the lock portion that locks in the state in which the support portion 60 is extended is not limited to the connection portion between the second support portion 71 and the support support portion 50, but the first support portion 61 and the second support portion 71. It can be a connection part or a connection part between the first support part 61 and the handrail body 20.

  The arrangement position of the fixing portion that fixes the tilt position of the handrail main body 20 at the retracted position is not limited to the connection portion between the second support portion 71 and the support support portion 50, but the connection between the handrail main body 20 and the main body support portion 40. It can be set as a part, a connection part of the 1st support part 61 and the 2nd support part 71, and a connection part of the 1st support part 61 and handrail main part 20.

  -As a structure of the fixing part that fixes the tilting position of the handrail body 20 at the retracted position, a structure in which the handrail body 20 is fastened by a band whose one end is fixed to the support wall 15 of the vehicle, or an engagement fixed to the support wall 15 Arbitrary structures such as a structure in which the handrail body 20 is engaged with a support portion (for example, a clip that is elastically deformed) can be adopted.

-You may arrange | position the locking part which locks the tilting position of the handrail main body 20 in a deployment position, and the fixing | fixed part fixed in a storing position in the position which left | separated.
-Lock hole 121 provided in the 2nd support part 71 may be omitted. In this case, for example, a structure in which one of the first support part 61 and the second support part 71 abuts the other when the tilting position of the handrail main body 20 becomes the deployed position is adopted. 2 A structure in which relative tilt with the support portion 71 is restricted at the deployed position, and a portion that restricts the relative movement can be used as a lock portion.

  The support part 60 may be bent in the same direction when the handrail body 20 is tilted at the retracted position and at the unfolded position. In addition, when the tilt position of the handrail body 20 is the deployed position, the tilt center L2 of the second hinge part 80, the tilt center L3 of the third hinge part 90, and the tilt center L4 of the fourth hinge part 100 are collinear. Can be arranged side by side.

  -The 1st support part 61 should just be a thing with the shape where the intermediate part in the extending direction was bent, such as not only the thing of the curved shape but the bent shape. Further, as the second support portion 71, a shape in which the intermediate portion in the extending direction is bent can be adopted. In short, by bending a part of the first support part, the second support part, and the handrail body, by forming a space that will not be lost by the bending and stretching operation of the support part in the part where the finger may enter, It is possible to prevent the fingers from being pinched during the operation of the handrail body.

-You may form the 1st support part 61 in the shape extended linearly.
The outer shape of the operation unit 110 is not limited to the kidney shape, but can be changed to an arbitrary shape such as a rectangular shape, a round shape, or an elliptical shape. Further, the operation unit 110 is not limited to adopting a plate shape, but a lever shape extending in parallel with the second support portion 71 or a column shape extending in parallel with the tilting center L4 of the second support portion 71. Arbitrary shapes such as (cylindrical shape or polygonal column shape) can be adopted.

  The operation unit 110 may be omitted. In this case, the tilting position of the handrail main body 20 can be changed by directly grasping and operating the support portion 60 or by directly grasping and operating the handrail main body 20 accordingly.

  -The shape of the handrail body 20 can be arbitrarily changed. For example, the handrail body has a shape in which the base end portion becomes a horizontal portion extending in the horizontal direction when the handrail is used, and the tip end portion is inclined so as to become a lower position toward the tip when the handrail is used. It can be made into the shape used as the inclined part extended. In addition, the handrail main body can have a shape in which the horizontal portions and the inclined portions are alternately arranged, and a shape including three or more horizontal portions and two or more inclined portions. In addition, the handrail main body can be formed in a shape that extends linearly or in a shape that extends in an arc.

  -The handrail of the said embodiment is applicable also to the handrail attached to a vehicle so that the handrail main body 20 may tilt in arbitrary directions (for example, horizontal direction) other than an up-down direction. In addition, the handrail of the above-described embodiment can be applied to a handrail provided other than the vehicle such as a wall of a house.
