Description

Technical Field

[0001] The present invention relates to a vehicle handle, and more particularly to a vehicle handle installed inside a vehicle such as a railway vehicle or a bus.

Background Art

[0002] Generally, inside a vehicle such as a railway vehicle or a bus (for example, the ceiling part), a vehicle handle is provided that a standing passenger can grasp to maintain their posture. For example, Patent Documents 1 and 2 disclose vehicle handles installed in the passenger compartment of a vehicle. The vehicle handle 100 disclosed in Patent Document 1 includes, as shown in FIGS. 15(A) and (B), a suspension belt 102 suspended at a predetermined interval on a support pipe 101 extending in the longitudinal direction of the vehicle, and an annular handle body 103 held at the lower end of the suspension belt 102. The upper end of the suspension belt 102 is wound around the support pipe 101, and the folded-back portion is fixed by a stopper 104. Also, the lower end of the suspension belt 102 is wound around the upper arc portion 103a of the handle body 103 and is fixed in a state where the folded-back portion is fitted into a square tube portion 105. Therefore, the handle body 103 is formed in an annular shape, and the left-right direction of the handle body 103 coincides with the arrangement direction of the suspension belts (the longitudinal direction of the support pipe 101).

[0003] Furthermore, the vehicle suspension strap 200 disclosed in Patent Document 2, as shown in Figures 16(A) and (B), comprises a suspension belt 202 suspended at predetermined intervals from a support pipe 201 extending from the upper part of the vehicle, and a triangular annular suspension strap body 203 having a triangular apex 203a held at the lower end of the suspension belt 202 and a horizontal base 203b located below it. The upper end of the suspension belt 202 is wound around the support pipe 201. The lower end of the suspension belt 202 is inserted into an elongated hole extending in the front-back direction in the triangular apex 203a of the suspension strap body 203, with the belt piece 206 sandwiched between them, and is fixed from the left and right directions by a screw member 204. In addition, the middle part of the suspension belt 202 and the upper end of the belt piece 206 are fitted into a rectangular tube portion 205. Therefore, the suspension hand body 203 is formed in a triangular ring shape with its horizontal base portion 203b located downwards, and the left-right direction of the suspension hand body 203 is perpendicular to the arrangement direction of the suspension belts 202 (the longitudinal direction of the support pipes 201). [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Utility Model Publication No. 56-35434 [Patent Document 2] Utility Model Registration No. 3139665 Gazette [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] However, the vehicle straps 100 and 200 described in Patent Documents 1 and 2 had the following problems. In other words, in the vehicle hand strap 100 of Patent Document 1, the hand strap body 103 is formed in an annular shape, and the left-right direction of the hand strap body 103 coincides with the arrangement direction of the suspension belts 102 (the longitudinal direction of the support pipe 101). Therefore, passengers lined up in the arrangement direction of the suspension belts 102 (the longitudinal direction of the support pipe 101) can generally see the annular hollow portion 103c of the hand strap body 103 from the front, and even when the vehicle shakes, the annular hollow portion 103c of the hand strap body 103 is easily visible, and they can quickly insert their fingers into the annular hollow portion 103c and grasp the lower arc portion 103b of the hand strap body 103. However, because the hand strap body 103 is formed in an annular shape, there is a problem that for short passengers, the area of ​​the lower arc portion 103b to grasp is narrow, and they cannot grasp it stably using their whole fingers.

[0006] Furthermore, in the vehicle hand strap 200 of Patent Document 2 described above, the hand strap body 203 is formed in a triangular ring shape with the horizontal base portion 203b located downwards. This provides a wide gripping area for the base portion 203b, allowing even short passengers to grip it stably using their entire fingers. However, the left-right direction of the hand strap body 203 is perpendicular to the arrangement direction of the suspension belt 202 (the longitudinal direction of the support pipe 201). Therefore, passengers generally view the triangular ring hand strap body 203 from the side, making it difficult to see the triangular ring hollow portion 203c of the hand strap body 203. Consequently, when the vehicle shakes, it is difficult to quickly insert fingers into the triangular ring hollow portion 203c of the hand strap body 203 and securely grip the base portion 203b of the hand strap body 203.

[0007] Furthermore, in the vehicle hand strap 200 of the above-mentioned Patent Document 2, the lower end of the suspension belt 202 is inserted into an elongated hole extending in the front-back direction in the triangular top portion 203a of the hand strap body 203, with the belt piece 206 sandwiched between them, and is fixed from the left and right directions by a screw member 204. As a result, in order to fix the lower end of the suspension belt 202, the volume and weight of the hand strap body 203 increase, which goes against the goals of weight reduction and resource conservation, and there is also the problem that the impact when the hand strap body 203 hits a passenger due to the shaking of the vehicle, etc.

[0008] Furthermore, as shown in Figure 17, the human hand skeleton TK has a structure in which the fingers other than the thumb Y1 (index finger Y2, middle finger Y3, ring finger Y4, little finger Y5) have a distal phalanx K1 at the tip of the finger, a middle phalanx K2 in the middle, and a proximal phalanx K3 at the base, and each joint flexes in a direction opposite to the thumb Y1, allowing it to grasp objects. In the vehicle hand straps 100 and 200 of the above-mentioned Patent Documents 1 and 2, as shown in Figure 18, the lower arc portion 103b and base portion 203b of the hand strap body 103 and 203 are formed in a circular cross-section or an oval cross-section close to a circle. Therefore, when the thumb Y1 and the other fingers (index finger Y2, middle finger Y3, ring finger Y4, little finger Y5) grasp the hand strap body 103 and 203, the bending angle θ1 of the first joint P1 between the distal phalanx K1 and the middle phalanx K2 of the other fingers must be bent to an angle equal to or less than the bending angle θ2 of the second joint P2 between the middle phalanx K2 and the proximal phalanx K3. However, generally, the distal phalanx K1 is formed to be shorter than the middle phalanx K2 and the proximal phalanx K3, and the first joint P1 tends to be less flexible than the second joint P2. On the other hand, the middle phalanx K2 and proximal phalanx K3 are formed to be longer than the distal phalanx K1, and the second joint P2 tends to be more flexible than the first joint P1. Therefore, when gripping the handrail body 103, 203, there is a need for a vehicle handrail that can be gripped comfortably without placing excessive strain on the first joint P1 of the gripping finger, which is less flexible.

[0009] The present invention was made to solve these problems, and aims to provide a vehicle strap that allows for quick gripping of the strap body, has a wide gripping area, reduces the burden on the joints of the fingers gripping, is easy to grip, and contributes to the weight reduction and resource conservation of the strap body. [Means for solving the problem]

[0010] To achieve the above objective, the vehicle suspension strap according to the present invention has the following configuration. (1) A vehicle hand strap comprising a suspension belt suspended at predetermined intervals in the belt width direction from the belt support portion of the vehicle, and an annular hand strap body held by the suspension belt, which a passenger can grasp to maintain their posture, The aforementioned handrail body comprises a belt holding portion formed in a semi-circular shape when viewed from the front, with the lower end of the suspension belt being wound in the front-back direction and extending in the left-right direction to a support shaft portion in the belt groove portion in the upper center, and gripping portions extending horizontally from both lower ends of the belt holding portion for the passenger to grasp, and is formed in a semi-circular ring shape when viewed from the front. The gripping portion is formed in a vertically elongated cross-sectional shape, and the front and back surfaces, which the fingers contact respectively, are bent or curved at an obtuse angle in a direction that causes the middle portion in the vertical direction to bulge outward.

[0011] In the present invention, the hand strap body has a belt holding portion formed in a semi-circular shape when viewed from the front, with the lower end of the suspension belt wound around the front and back and a support shaft portion extending in the left and right directions in the belt groove portion in the upper center, and gripping portions extending horizontally from both lower ends of the belt holding portion for passengers to grasp. As it is formed in a semi-circular ring shape when viewed from the front, the left and right direction of the hand strap body coincides with the direction of arrangement of the suspension belts, and generally, passengers lined up along the direction of arrangement of the suspension belts can see the semi-circular ring hollow portion of the hand strap body from the front. Therefore, even when the vehicle shakes, the semi-circular ring hollow portion of the hand strap body is easily visible, and passengers can quickly insert their fingers into the semi-circular ring hollow portion and securely grasp the gripping portion of the hand strap body.

[0012] Furthermore, since the gripping portion for passengers extends horizontally from both lower ends of the belt holding portion, a wide area for passengers to grip can be secured downwards, allowing even short passengers to stably grasp the handrail. In addition, since the lower end of the suspension belt is restricted by the edge of the belt groove, displacement of the handrail relative to the suspension belt can be avoided, and even when the vehicle shakes, passengers gripping the handrail can easily maintain their posture.

[0013] Furthermore, the belt holding portion is formed in a semi-circular shape when viewed from the front, with the lower end of the suspension belt wound around it in the front-back direction and a support shaft portion extending in the left-right direction in the belt groove portion in the upper center. This effectively reduces the volume and weight of the belt holding portion in the upper center portion that is held by the lower end of the suspension belt, while expanding the space in the semi-circular ring hollow portion where passengers can insert their fingers. As a result, it is possible to promote weight reduction and resource conservation in the suspension hand itself.

[0014] Furthermore, the gripping portion is formed with a vertically elongated cross-sectional shape, and the front and back surfaces, which the fingers contact respectively, are bent or curved at an obtuse angle in the direction that causes the middle section in the vertical direction to bulge outward. As a result, the front and back surfaces intersect at an acute angle at the upper and lower positions of the gripping portion, and bend or curve at an obtuse angle at the intermediate position in the vertical direction of the gripping portion. Therefore, when a passenger's thumb and other fingers (index finger, middle finger, ring finger, little finger) grip the gripping portion of the handrail body, the second joint between the middle phalanx and the proximal phalanx of the other fingers is bent at an acute angle along the front and back surfaces above the intermediate position where they intersect at an acute angle above the gripping portion, and the first joint between the distal phalanx and the middle phalanx of the fingertip is bent at an obtuse angle along the front or back surface that is bent or curved at an obtuse angle at the intermediate position in the vertical direction. Therefore, the bending angle of the first joint, which is difficult to bend, can be made greater than the bending angle of the second joint, which is easier to bend, thus avoiding bending the first joint to an unnatural angle of less than 90 degrees. As a result, when gripping the handle, excessive strain on the first joint of the gripping finger can be avoided, allowing for a more comfortable grip.

[0015] Therefore, according to the present invention, it is possible to provide a vehicle strap that allows for quick gripping of the strap body, has a wide gripping area, reduces the burden on the joints of the fingers gripping, is easy to grip, and contributes to the weight reduction and resource conservation of the strap body.

[0016] (2)(1) In the vehicle strap described above, The belt holding portion comprises an outer peripheral flange portion extending in a semi-circular arc shape in the circumferential direction on the outer peripheral side, and a mountain-shaped inner peripheral rib portion rising on the inner peripheral side of the outer peripheral flange portion. The outer peripheral flange portion and the inner peripheral rib portion are formed in a cross-sectional shape that intersects in a T-shape.

[0017] In this invention, the belt holding portion comprises an outer peripheral flange portion extending in a semi-circular arc shape in the circumferential direction on the outer peripheral side, and a mountain-shaped inner peripheral rib portion rising on the inner peripheral side of the outer peripheral flange portion. Since the outer peripheral flange portion and the inner peripheral rib portion are formed in a cross-sectional shape that intersects in a T-shape, the bending strength in the direction normal to the semi-circular outer peripheral flange portion can be efficiently reinforced with a small cross-sectional area by the mountain-shaped inner peripheral rib portion. Therefore, while ensuring the necessary bending strength in the lifting hand body, further weight reduction and resource conservation can be achieved.

[0018] (3)(2) In the vehicle strap described above, The outer peripheral flange portion is formed such that the flange width in the front-back direction gradually widens from the lower end to the upper central portion of the belt holding portion. The front and back edge surfaces of the outer peripheral flange portion and the front and back contact surfaces of the gripping portion below the intermediate portion are connected on the same plane.

[0019] In the present invention, the outer peripheral flange portion is formed such that the flange width in the front-back direction gradually widens from the lower end portion to the upper central portion in the belt holding portion, and the front edge surface and the back edge surface of the outer peripheral flange portion, and the front contact surface and the lower back contact surface below the middle portion of the gripping portion are connected on the same plane, respectively. Therefore, while reducing the weight and resource consumption of the hanger body, the load of the passenger on the gripping portion can be reliably transmitted to the suspension belt through the belt holding portion with enhanced rigidity by the outer peripheral flange portion that gradually widens upward. Further, by connecting the front edge surface and the back edge surface of the outer peripheral flange portion and the front contact surface and the lower back contact surface below the middle portion of the gripping portion on the same plane, the integration of the belt holding portion and the gripping portion is enhanced, the appearance is improved, and in case of an emergency, the lower end side of the belt holding portion can be easily gripped. Therefore, it is possible to further promote the improvement of weight reduction and resource saving and the improvement of convenience for the hanger body.

[0020] (4) In the vehicle hanger according to (2) or (3), The inner peripheral rib portion is formed such that the rib height gradually increases from the lower end portion to the upper central portion in the belt holding portion, The inner peripheral end portion of the inner peripheral rib portion and the upper end portion of the gripping portion are continuously connected with the same width.

[0021] In the present invention, the inner peripheral rib portion is formed such that the rib height gradually increases from the lower end portion to the upper central portion in the belt holding portion, and the inner peripheral end portion of the inner peripheral rib portion and the upper end portion of the gripping portion are continuously connected with the same width. Therefore, while achieving weight reduction and resource savings of the hanging handle body, the load of the passenger on the gripping portion can be reliably transmitted to the hanging belt through the belt holding portion with increased rigidity by the inner peripheral rib portion whose rib height gradually increases upward. In addition, by connecting the inner peripheral end portion of the inner peripheral rib portion and the upper end portion of the gripping portion continuously with the same width, the sense of unity between the belt holding portion and the gripping portion is enhanced, improving the appearance, and in case of an emergency, the lower end side of the belt holding portion can be easily gripped. Therefore, it is possible to further promote the improvement of weight reduction and resource savings and the improvement of convenience for the hanging handle body.

[0022] (5) In the vehicle hanging handle according to any one of (1) to (4), the gripping portion is curved in an arch shape upward or downward at a position below the center of the semi-arc of the belt holding portion.

[0023] In the present invention, the gripping portion is curved in an arch shape upward or downward at a position below the center of the semi-arc of the belt holding portion. Therefore, while ensuring sufficient space for the passenger's finger to enter the semi-arc ring hollow portion, when the thumb and other fingers (index finger, middle finger, ring finger, little finger) grip the gripping portion, the gap between the finger and the gripping portion caused by differences in hand size, length and thickness between fingers, etc. can be reduced by gripping along the arch-shaped curved gripping portion. Therefore, while enhancing the versatility with respect to hand size, etc. of the hanging handle body, the gripping portion can be gripped more easily.

[0024] (6) In the vehicle hanging handle according to any one of (1) to (5), the hanging belt is divided into an upper hanging belt supported by the belt support portion and a lower hanging belt wound around the support shaft portion of the hanging handle body. The upper suspension belt and the lower suspension belt are connected by a belt connector formed to allow the lower suspension belt to rotate horizontally relative to the upper suspension belt.

[0025] In this invention, the suspension belt is divided into an upper suspension belt supported by a belt support and a lower suspension belt wound around the pivot of the hand strap body. The upper and lower suspension belts are connected by a belt connector that allows the lower suspension belt to rotate horizontally relative to the upper suspension belt. Therefore, even if the length of the suspension belt is short and it is difficult to rotate the hand strap body from a direction that coincides with the direction of the suspension belt arrangement to a direction different from that, the orientation (left-right direction) of the hand strap body held can be changed via the belt connector according to the passenger's preference. For example, in a crowded train, passengers facing different directions can each grasp the hand strap body in a posture that is comfortable for them.

[0026] (7)(6) In the vehicle strap described above, The belt connector is characterized by comprising: an upper connecting portion connected to the upper suspension belt; a lower connecting portion connected to the lower suspension belt; a middle connecting portion that allows the upper connecting portion and the lower connecting portion to rotate horizontally; and a biasing member that engages with the upper connecting portion and the lower connecting portion and biases the upper connecting portion and the lower connecting portion in a direction in which the left-right direction of the suspension hand body coincides with the arrangement direction of the suspension belts.

[0027] In this invention, the belt connector includes an upper connecting portion connected to the upper suspension belt, a lower connecting portion connected to the lower suspension belt, a middle connecting portion that allows the upper and lower connecting portions to rotate horizontally, and a biasing member that engages with the upper and lower connecting portions and biases the upper and lower connecting portions in a direction that coincides with the left-right direction of the hand strap body and the arrangement direction of the suspension belts. Therefore, even if the orientation (left-right direction) of the hand strap body held by the passenger is changed according to the passenger's preference, when the passenger releases the hand strap body and moves, the biasing member automatically returns the orientation (left-right direction) of the hand strap body to a direction that coincides with the arrangement direction of the suspension belts. As a result, the orientation (left-right direction) of the hand strap body can be quickly returned to a state where it can be grasped by the next passenger. [Effects of the Invention]

[0028] According to the present invention, it is possible to provide a vehicle strap that allows for quick gripping of the strap body, has a wide gripping area, reduces the burden on the joints of the fingers gripping, is easy to grip, and contributes to the weight reduction and resource conservation of the strap body.

[Modes for carrying out the invention]

[0030] Next, a vehicle sling representing one aspect of this embodiment will be described in detail with reference to the drawings. Specifically, the vehicle slings of the first and second embodiments of this embodiment will be described in detail. Furthermore, modified examples (first to fifth modifications) of the sling body of the vehicle sling according to this embodiment will be described in detail.

[0031] <Vehicle carrying handle according to this embodiment (first embodiment)> First, the vehicle sling of the first embodiment according to this embodiment will be described using Figures 1 to 8. Figure 1 shows a perspective view of the vehicle sling of the first embodiment according to this embodiment. Figure 2 shows a front view of the sling body of the vehicle sling shown in Figure 1. Figure 3 shows the cross-sectional view AA shown in Figure 2. Figure 4 shows the cross-sectional view BB shown in Figure 2.

Figure 6 shows a view along arrow C shown in Figure 2. Figure 7 shows a comparison of the sling body shown in Figure 2 and the sling body described in Patent Document 1. Figure 8 shows a comparison of the sling body shown in Figure 2 and the sling body described in Patent Document 2.

[0032] As shown in Figure 1, the vehicle hand strap 10 of the first embodiment according to this embodiment comprises a suspension belt 1 suspended at predetermined intervals from the belt support portion 3 of the vehicle SR, and an annular hand strap body 2 held at the lower end 11 of the suspension belt 1, allowing passengers to grasp the hand strap body 2 for posture maintenance. The suspension belts 1 of this vehicle hand strap 10 are arranged at predetermined intervals in the belt width direction.

[0033] Here, vehicle SR includes railway cars, buses, and other vehicles that can accommodate standing passengers. The belt support section 3 is, for example, a support pipe 3P fixed to the ceiling of vehicle SR, but is not necessarily limited to the support pipe 3P. Fasteners 31 are fixed to the support pipe 3P to secure the upper end 12 of the wound suspension belt 1 at predetermined intervals. The suspension belt 1 is also secured between the belt support section 3 and the suspension hand body 2 by belt fasteners 4. The belt fastener 4 shown in Figure 1 has a set screw section 41 for fastening the suspension belt 1 from both sides and a rectangular tube section 42 into which the suspension belt 1 is fitted, but the belt fastener 4 may also be composed of only the set screw section 41 or the rectangular tube section 42.

[0034] Furthermore, as shown in Figures 1 to 6, the handrail body 2 has a belt holding portion 21 formed in a semi-circular shape when viewed from the front, with a support shaft portion 211 extending in the left-right direction, around which the lower end 11 of the suspension belt 1 is wound in the front-back direction, in the belt groove portion 212a of the upper central portion 212, and a gripping portion 22 that extends horizontally from both lower ends 213 of the belt holding portion 21 and is grasped by passenger JK, and is formed in a semi-circular ring shape when viewed from the front. Note that the above terms "semi-circular shape," "horizontal shape," and "semi-circular ring" do not mean "semi-circular," "horizontal," and "semi-circular ring" in the strict sense, but rather mean that it is sufficient if it is approximately "semi-circular," approximately "horizontal," and approximately "semi-circular ring." Hereafter, when "~shape" is written in expressions describing shape and form, it shall be interpreted in the same way as above unless otherwise noted.

[0035] Therefore, the left-right direction of the hand strap body 2 coincides with the arrangement direction of the suspension belts 1, and generally, passengers JK lined up along the arrangement direction of the suspension belts 1 can see the semi-circular ring hollow portion 2a of the hand strap body 2 from the front. As a result, even when the vehicle SR shakes, the semi-circular ring hollow portion 2a of the hand strap body 2 is easily visible, and passengers can quickly insert their fingers into the semi-circular ring hollow portion 2a to securely grasp the gripping portion 22 of the hand strap body 2.

[0036] Furthermore, a belt groove 212a is formed in the upper central part 212 of the belt holding part 21, with a width equal to that of the suspension belt 1. Within the belt groove 212a, a support shaft 211 is extended in the left-right direction, which winds the lower end 11 of the suspension belt 1 in the front-back direction. The support shaft 211 is formed in a circular cross-section with a diameter sufficient to withstand the suspension load of the vehicle suspension hand 10. The suspension hand body 2 is made of a thermoplastic resin material with excellent impact resistance and durability, such as polycarbonate.

[0037] Furthermore, the gripping portion 22 that the passenger JK grasps extends horizontally from both lower ends 213 of the belt holding portion 21, which is formed in a semi-circular shape when viewed from the front. Therefore, a wide area of ​​the gripping portion 22 that the passenger JK grasps can be secured downwards. For example, as shown in Figure 7, the gripping portion 22 of the hand strap body 2 eliminates the difficult-to-grip annular X-region compared to the annular hand strap body 103 described in Patent Document 1, and the horizontal area that is easy to grip can be greatly expanded. Therefore, even a short passenger JK can stably grasp the hand strap body 2.

[0038] Furthermore, since the hand strap body 2 has a support shaft portion 211 in the belt groove portion 212a of the upper central portion 212, around which the lower end portion 11 of the suspension belt 1 is wound in the front-to-back direction and extends in the left-to-right direction, the lower end portion 11 of the suspension belt 1 is restricted by the edge of the belt groove portion 212a, preventing the hand strap body 2 from shifting position in the left-to-right direction relative to the suspension belt 1, and allowing the gripping portion 22 of the hand strap body 2 to rotate in the front-to-back direction around the circular cross-section support shaft portion 211. Therefore, even if the vehicle SR shakes, the passenger JK who is gripping the hand strap body 2 can easily maintain their posture or easily correct their tilted posture.

[0039] Furthermore, the belt holding portion 21 has a support shaft portion 211 that extends in the left-right direction and around the lower end 11 of the suspension belt 1, and is located in the belt groove portion 212a of the upper central portion 212, and is formed in a semi-circular shape when viewed from the front. This allows for an expansion of the space for the semi-circular ring hollow portion 2a into which the passenger JK's fingers can be inserted, while effectively reducing the volume and weight of the belt holding portion 21 in the upper central portion 212 that is held by the lower end 11 of the suspension belt 1. For example, as shown in Figure 8, compared to the triangular ring-shaped suspension hand body 203 described in Patent Document 2, the triangular Y1 region can be reduced to an arc-shaped Y2 region. Therefore, weight reduction and resource conservation of the suspension hand body 2 can be promoted.

[0040] Furthermore, as shown in Figures 1 to 5, the gripping portion 22 is formed in a vertically elongated cross-sectional shape, with the front surface 221 and back surface 222, which the fingers contact on the front and back sides respectively, being bent or curved at an obtuse angle in a direction that causes the intermediate portions 221a and 222a in the vertical direction to bulge outward. Here, the gripping portion 22 is formed in a vertically elongated hexagonal cross-sectional shape, composed of an upper end portion 223 and a lower end portion 224 that are flat in the front and back directions, and an upper front surface 221b and a lower front surface 221c, and an upper back surface 222b and a lower back surface 222c, which are bent outward at an obtuse angle at intermediate positions Q3 and Q4 in the vertical direction. Furthermore, the vertical distance t1 between the upper end 223 and the lower end 224 of the gripping portion 22 is formed to be larger than the front-to-back distance t2 between the middle portion 221a of the front contact surface 221 and the middle portion 222a of the back contact surface 222.

[0041] In this case, as shown by dashed lines in Figure 3, the front contact surface 221 and the back contact surface 222 of the gripping portion 22 intersect at obtuse angles at intermediate vertical positions Q3 and Q4 of the gripping portion 22, respectively, and intersect at acute angles at the upper position Q1 and the lower position Q2 of the gripping portion 22. That is, the upper front contact surface 221b and the lower front contact surface 221c intersect at obtuse angles at intermediate position Q3 on the front side of the gripping portion 22, and the upper back contact surface 222b and the lower back contact surface 222c intersect at obtuse angles at intermediate position Q4 on the back side of the gripping portion 22. The internal angle α1 of each intersection is preferably around 150 to 160 degrees. Furthermore, the upper front surface 221b and the upper back surface 222b intersect at an acute angle at the upper position Q1 of the gripping portion 22, and the lower front surface 221c and the lower back surface 222c intersect at an acute angle at the lower position Q2 of the gripping portion 22. The upper intersection interior angle α2 is preferably about 30 to 40 degrees, and the lower intersection interior angle α3 is preferably about 10 to 20 degrees.

[0042] Furthermore, the above-described structure of the front surface 221 and back surface 222 of the gripping portion 22 allows passenger JK's thumb Y1 and other fingers (index finger Y2, middle finger Y3, ring finger Y4, little finger Y5) to grip the gripping portion 22 of the handrail body 2, causing the first joint P1 between the distal phalanx K1 at the tip of the other fingers and the middle phalanx K2 to bend at an obtuse angle along the front surface 221 or back surface 222, which are bent at an obtuse angle at the intermediate vertical positions Q3 and Q4. In addition, the second joint P2 between the middle phalanx K2 and the proximal phalanx K3 at the base to bend at an acute angle along the upper front surface 221b and upper back surface 222b, which intersect at an acute angle at the upper position Q1 of the gripping portion 22. Therefore, the bending angle β1 of the first joint P1 of the other fingers can be made greater than the bending angle β2 of the second joint P2, thus avoiding the first joint P1, which is difficult to bend, being forced to bend to an unnatural angle of 90 degrees or less. As a result, when gripping the gripping part 22, excessive strain on the first joint P1 of the gripping finger can be prevented, allowing for a comfortable grip.

[0043] Therefore, the vehicle hand strap 10 of this first embodiment allows for quick gripping of the hand strap body 2, has a wide gripping area, reduces the burden on the joints of the fingers gripping, is easy to grip, and contributes to weight reduction and resource conservation of the hand strap body 2.

[0044] Furthermore, as shown in Figures 1 to 4, in the vehicle suspension strap 10 of this first embodiment, the belt holding portion 21 of the suspension strap body 2 is preferably formed in a T-shape, with the outer peripheral flange portion 21H extending in a semi-circular arc shape in the circumferential direction on the outer peripheral side, and the mountain-shaped inner peripheral rib portion 21R rising on the inner peripheral side of the outer peripheral flange portion 21H.

[0045] In this case, the bending strength in the direction normal to the semi-circular outer flange portion 21H can be efficiently reinforced with a small cross-sectional area by the mountain-shaped inner rib portion 21R. Therefore, while ensuring the necessary bending strength in the suspension body 2, further weight reduction and resource conservation can be achieved.

[0046] Furthermore, it is preferable that the front wall surface 21R2 and the back wall surface 21R3 extending from the inner end portion 21R1 of the inner rib portion 21R to the front edge surface 21H1 and back edge surface 21H2 of the outer flange portion 21H be formed as curved surfaces that are concave inward in an arc shape. This is because it is possible to further reduce weight and conserve resources while ensuring the bending strength of the belt holding portion 21. In addition, when wiping the strap body 2, the front wall surface 21R2 and the back wall surface 21R3 can be wiped in a circular motion along the concave shape at once, which also contributes to shortening cleaning time. Furthermore, it is preferable that the outer circumferential surface 21H3 of the outer flange portion 21H be formed as a curved surface that bulges slightly outward with a constant curvature between the front edge surface 21H1 and the back edge surface 21H2. This is because it is possible to improve the appearance and further mitigate the impact when the strap body 2 hits a passenger due to the shaking of the vehicle, etc.

[0047] Furthermore, as shown in Figures 1, 3, 4, and 6, in the vehicle suspension strap 10 of this first embodiment, the outer peripheral flange portion 21H of the belt holding portion 21 of the suspension strap body 2 is formed such that the flange width ω(ω1, ω2) in the front-back direction gradually widens from the lower end portion 213 to the upper central portion 212 of the belt holding portion 21, and the front edge surface 21H1 and the back edge surface 21H2 of the outer peripheral flange portion 21H and the front contact surface 221c and the lower back contact surface 222c of the gripping portion 22 below the intermediate portions 221a and 222a are preferably connected on the same plane.

[0048] In this case, while reducing the weight and resource consumption of the hand strap body 2, the load of the passenger JK on the gripping portion 22 can be reliably transmitted to the suspension belt 1 via the belt holding portion 21, which has increased rigidity due to the outer peripheral flange portion 21H that gradually widens towards the top. Furthermore, by connecting the front edge surface 21H1 and the back edge surface 21H2 of the outer peripheral flange portion 21H, and the front contact surface 221c and the lower back contact surface 222c of the gripping portion 22 below the intermediate portions 221a and 222a, on the same plane, the sense of unity between the belt holding portion 21 and the gripping portion 22 is enhanced, improving the appearance, and in an emergency, the lower end of the belt holding portion 21 can be easily grasped. Therefore, improvements in weight reduction, resource conservation, and convenience for the hand strap body 2 can be further promoted.

[0049] Furthermore, by forming the front edge surface 21H1 of the outer peripheral flange portion 21H and the lower front contact surface 221c of the gripping portion 22 on the same plane, and by forming the back edge surface 21H2 of the outer peripheral flange portion 21H and the lower back contact surface 222c of the gripping portion 22 on the same plane, the sense of unity between the belt holding portion 21 and the gripping portion 22 can be enhanced, further improving the aesthetic appearance of the design.

[0050] Furthermore, as shown in Figures 2 and 4, in the vehicle suspension strap 10 of this first embodiment, the inner circumferential rib portion 21R of the belt holding portion 21 of the suspension strap body 2 is formed such that the rib height d3 gradually increases from the lower end portion 213 to the upper central portion 212 of the belt holding portion 21, and it is preferable that the inner circumferential end portion 21R1 of the inner circumferential rib portion 21R and the upper end portion 223 of the gripping portion 22 are continuously connected with the same width ω3.

[0051] In this case, while reducing the weight and resource consumption of the hand strap body 2, the load of the passenger JK on the gripping portion 22 can be reliably transmitted to the suspension belt 1 via the belt holding portion 21, whose rigidity is increased by the inner circumferential rib portion 21R, where the rib height d3 gradually increases as it goes upwards. Furthermore, by continuously connecting the inner circumferential end portion 21R1 of the inner circumferential rib portion 21R and the upper end portion 223 of the gripping portion 22 with the same width ω3, the sense of unity between the belt holding portion 21 and the gripping portion 22 is enhanced, improving the appearance, and in an emergency, the lower end of the belt holding portion 21 can be easily grasped. Therefore, improvements in weight reduction, resource conservation, and convenience for the hand strap body 2 can be further promoted.

[0052] Furthermore, as shown in Figure 2, in the vehicle suspension handle 10 of this first embodiment, the gripping portion 22 is preferably curved upward in an arch shape at a position below the semicircular center TB of the belt holding portion 21. Here, the semicircular center TB of the belt holding portion 21 is formed at the center position of radius R1 with respect to the outer peripheral surface 21H3 of the outer peripheral flange portion 21H (the intersection of the horizontal line X and the vertical line Y). Also, the distance from the horizontal line X passing through the semicircular center TB to the upper end portion 223 of the gripping portion 22 is formed such that the distance d2 at both ends in the left-right direction is greater than the distance d1 at the center in the left-right direction.

[0053] In this case, while ensuring sufficient space for passenger JK's fingers to insert into the semi-circular hollow portion 2a, when the thumb Y1 and other fingers (index finger Y2, middle finger Y3, ring finger Y4, little finger Y5) grip the gripping portion 22, the gap between the fingers and the gripping portion 22, which arises from differences in hand size, length and thickness between fingers, etc., can be reduced by gripping along the arch-shaped curved gripping portion 22. Therefore, the versatility of the hand strap body 2 for different hand sizes is increased, and the gripping portion 22 can be gripped even more easily.

[0054] Furthermore, it is preferable that the radius R2 of the upper end 223 of the gripping portion 22, which curves upward in an arch shape, is greater than the radius R1 of the outer surface 21H3 of the outer flange portion 21H. This is because it allows for a wider space to be secured against the back of the hand when gripping the gripping portion 22. In addition, it is preferable that the vertical distance t1 between the upper end 223 and the lower end 224 of the gripping portion 22 be constant in the left-right direction. This is because the bending angle of the finger joints that grip the gripping portion 22 is less affected by the gripping position, making it easier to grip.

[0055] <Vehicle carrying handle according to this embodiment (second embodiment)> Next, a vehicle sling according to the second embodiment of this embodiment will be described with reference to Figures 9 to 11. Figure 9 is a perspective view of the vehicle sling shown in Figure 1, showing the state in which the suspension belt is twisted and the sling body is rotated horizontally. Figure 10 shows a perspective view of the vehicle sling according to the second embodiment of this embodiment. Figure 11 shows a DD cross-sectional view of the same part shown in Figure 10.

[0056] As shown in Figures 10 and 11, the vehicle hand strap 10G of the second embodiment according to this embodiment comprises a suspension belt 1G suspended from the belt support portion 3 of the vehicle SR at predetermined intervals in the belt width direction, and an annular hand strap body 2 held at the lower end of the suspension belt 1G, and is a vehicle hand strap 10G that allows passengers to grasp the hand strap body 2 to maintain their posture.

[0057] Furthermore, the hand strap body 2 has a belt holding portion 21 formed in a semi-circular shape when viewed from the front, with a support shaft portion 211 extending in the left-right direction, around which the lower end of the suspension belt 1G is wound in the front-back direction, in the belt groove portion 212a of the upper central portion 212, and a gripping portion 22 that extends horizontally from both lower ends 213 of the belt holding portion 21 and is grasped by the passenger, and is formed in a semi-circular ring shape when viewed from the front. The gripping portion 22 is formed in a vertically elongated cross-sectional shape, and the front contact surface 221 and back contact surface 222, which the fingers contact on the front and back sides respectively, are bent or curved at an obtuse angle in a direction that causes the intermediate portions 221a and 222a in the vertical direction to bulge outward. This point is common with the vehicle hand strap 10 of the first embodiment described above. Here, the differences from the vehicle hand strap 10 of the first embodiment will be explained in detail, and common points will be denoted by common reference numerals, and detailed explanations will be omitted in principle.

[0058] In the vehicle suspension strap 10G of the second embodiment, the difference from the vehicle suspension strap 10 of the first embodiment is that the suspension belt 1G is divided into an upper suspension belt 12G supported by a belt support part 3 and a lower suspension belt 11G wound around the pivot part 211 of the suspension strap body 2, and the upper suspension belt 12G and the lower suspension belt 11G are connected by a belt connector 5 which is formed so that the lower suspension belt 11G can rotate horizontally relative to the upper suspension belt 12G.

[0059] In the first embodiment of the vehicle hand strap 10, as shown in Figure 9, if the suspension belt 1 can be made long in the vertical direction, the orientation (left-right direction) of the hand strap body 2 can be rotated to suit the passenger's preference by twisting the long suspension belt 1 in the horizontal direction. However, there are cases where, for example, the belt support part 3 cannot be placed at a high position in the vehicle SR, and the suspension belt 1 must be made short.

[0060] In this regard, in the vehicle hand strap 10G of the second embodiment, as shown in Figure 10, even if the length of the suspension belt 1G is short and it is difficult to twist the suspension belt 1G horizontally, the orientation (left-right direction) of the hand strap body 2 held by the passenger JK can be changed via the belt connector 5 according to the passenger JK's preference. Therefore, for example, in a crowded train, passengers facing different directions can each grasp the hand strap body 2 in a posture that is comfortable for them.

[0061] Furthermore, in the vehicle suspension strap 10G of this second embodiment, as shown in Figures 10 and 11, it is preferable that the belt connector 5 includes an upper connecting portion 51 connected to the upper suspension belt 12G, a lower connecting portion 52 connected to the lower suspension belt 11G, a middle connecting portion 53 that connects the upper connecting portion 51 and the lower connecting portion 52 so as to be rotatable in the horizontal direction, and a biasing member 56 that is locked to the upper connecting portion 51 and the lower connecting portion 52 and biases the upper connecting portion 51 and the lower connecting portion 52 in a direction in which the left-right direction of the suspension strap body 2 and the arrangement direction of the suspension belt 1G coincide.

[0062] In this case, even if the orientation (left-right direction) of the grabbed strap body 2 is changed according to the passenger JK's preference, when the passenger JK releases the grabbed strap body 2 and moves, the biasing member 56 can automatically return the orientation (left-right direction) of the grabbed strap body 2 to a direction that matches the arrangement direction of the suspension belt 1G. Therefore, the orientation (left-right direction) of the grabbed strap body 2 can be quickly returned to a state where it can be grasped by the next passenger.

[0063] The upper connecting portion 51 has an outer edge portion 51g formed in an upward-facing semi-circular arc shape, and an inner edge portion 51n formed in a hemispherical shape with a cylindrical cutout. The lower connecting portion 52 has an outer edge portion 52g formed in a downward-facing semi-circular arc shape, and an inner edge portion 52n formed in a hemispherical shape with a cylindrical cutout. The lower end of the upper connecting portion 51 has an annular groove portion 512 in which an upper flange portion 513 protrudes in the normal direction, and the upper end of the lower connecting portion 52 has an annular groove portion 522 in which a lower flange portion 523 protrudes in the normal direction. The upper flange portion 513 and the lower flange portion 523 are connected by a middle connecting portion 53 which has a pair of engaging protrusions 531 formed to engage vertically and slide horizontally. The middle connecting portion 53 is divided into two parts in the front-back direction, and the two parts are connected via a screw member 532.

[0064] Furthermore, an upper belt insertion hole 511 is formed at the upper end of the upper connecting portion 51, and an upper support shaft portion 54 extends from the inner edge portion 51n in the left-right direction to wind the lower end of the upper suspension belt 12G inserted through the upper belt insertion hole 511 in the front-back direction. Also, a lower belt insertion hole 521 is formed at the lower end of the lower connecting portion 52, and a lower support shaft portion 55 extends from the inner edge portion 52n in the left-right direction to wind the upper end of the lower suspension belt 11G inserted through the lower belt insertion hole 521 in the front-back direction. Spring seats 514 and 524 are formed on the inner edge portion 51n of the upper connecting portion 51 and the inner edge portion 52n of the lower connecting portion 52 to lock the upper end and lower end of the coil spring-shaped biasing member 56.

[0065] When passenger JK rotates the hand strap body 2, which they are holding, horizontally around the vertical axis (vertical line Y) of the suspension belt 1G, the lower connecting portion 52 connected to the lower suspension belt 11G can easily rotate horizontally while sliding against the upper connecting portion 51 connected to the upper suspension belt 12G and the middle connecting portion 53. Furthermore, when passenger JK releases the hand strap body 2, the biasing force of the biasing member 56 causes the lower connecting portion 52 connected to the lower suspension belt 11G to rotate horizontally while sliding against the upper connecting portion 51 connected to the upper suspension belt 12G and the middle connecting portion 53, returning it to its original position.

[0066] Furthermore, since the upper connecting portion 51 is formed as an upward-facing hemisphere and the lower connecting portion 52 is formed as a downward-facing semi-circular arc, the belt connector 5 as a whole is formed as a sphere. Therefore, passengers JK can easily grasp the belt connector 5. In addition, between adjacent passengers JK, one passenger JK can grasp the handrail body 2 and the other passenger JK can grasp the belt connector 5.

[0067] <Variation> Next, modified examples (Modifications 1 to 7) of the vehicle strap body according to this embodiment will be specifically described using Figures 12 to 14. Figure 12 is a detailed cross-sectional view of a modified gripping portion of the strap body shown in Figure 5, where (A) is a detailed cross-sectional view of the gripping portion of the strap body of the first modification, and (B) is a detailed cross-sectional view of the gripping portion of the strap body of the second modification. Figure 13 is a front view of a modified strap body shown in Figure 2, where (A) is a front view of the strap body of the third modification, (B) is a front view of the strap body of the fourth modification, and (C) is a front view of the strap body of the fifth modification. Figure 14 is a front view of a modified strap body shown in Figure 2, where (A) is a front view of the strap body of the sixth modification, and (B) is a front view of the strap body of the seventh modification.

[0068] (Differences 1 and 2) As shown in Figures 3 to 5, the gripping portion 22 of the vehicle handrails 10 and 10G according to this embodiment (first and second embodiment) is formed in a vertically elongated cross-sectional shape, with the front surface 221 and back surface 222, which the fingers contact on the front and back sides respectively, being bent or curved at an obtuse angle in a direction that causes the intermediate portions 221a and 222a in the vertical direction to bulge outward. Specifically, the gripping portion 22 is formed in a vertically elongated hexagonal cross-sectional shape, composed of an upper end portion 223 and a lower end portion 224 that are flat in the front and back directions, and an upper front surface 221b and a lower front surface 221c, and an upper back surface 222b and a lower back surface 222c, which are bent outward at an obtuse angle at intermediate positions Q3 and Q4 in the vertical direction.

[0069] However, the gripping portion 22 does not necessarily have to be formed in the hexagonal cross-sectional shape described above. It may also be formed as the gripping portions 22B and 22C of the handrail bodies 2B and 2C in the vehicle handrails 10B and 10C shown in Figure 12. In this case as well, it is possible to avoid bending the first joint P1, which is difficult to bend, to an unnatural angle of 90 degrees or less. As a result, when gripping the gripping portions 22B and 22C, it is possible to prevent excessive strain on the joints of the gripping fingers Y2 (Y3, Y4, Y5), and to grip them comfortably.

[0070] For example, as shown in Figure 12(A), the gripping portion 22B of the first modified hanger body 2B may be formed in a vertically elongated pentagonal cross-sectional shape, consisting of a flat lower end portion 224B and an upper front surface 221Bb and a lower front surface 221Bc, and an upper back surface 222Bb and a lower back surface 222Bc, which are formed by bending the intermediate portions 221Ba and 222Ba outward at obtuse angles at intermediate positions Q3 and Q4 in the vertical direction. The upper end portion 223B where the upper front surface 221Bb and the upper back surface 222Bb intersect is formed in an arc shape. The lower end portion 224B may also be formed in an arc shape.

[0071] Furthermore, as shown in Figure 12(B), the gripping portion 22C of the second modified hanger body 2C is formed in a vertically elongated oval cross-sectional shape, consisting of a flat lower end portion 224C and an upper front surface 221Cb and a lower front surface 221Cc, and an upper back surface 222Cb and a lower back surface 222Cc, which are curved outward at obtuse angles at intermediate positions Q3 and Q4 in the vertical direction. The upper end portion 223C where the upper front surface 221Cb and the upper back surface 222Cb intersect is formed in an arc shape. The lower end portion 224C may also be formed in an arc shape.

[0072] (Variations of the 3rd to 7th versions) As shown in Figure 2, the gripping portion 22 of the vehicle suspension straps 10 and 10G according to this embodiment (first and second embodiment) is curved upward in an arch shape at a position below the semicircular center TB of the belt holding portion 21. Furthermore, the vertical distance t1 between the upper end portion 223 and the lower end portion 224 of the gripping portion 22 is formed to be constant in the left-right direction.

[0073] However, the gripping portion 22 does not necessarily have to be formed in the curved shape described above, and may be formed as the gripping portions 22D, 22E, 22F, 22H, and 22I of the handrail bodies 2D, 2E, 2F, 2H, and 2I of the handrails 10D, 10E, 10F, 10H, and 10I shown in Figures 13 and 14. In this case as well, sufficient space can be secured for the passenger JK to insert their fingers into the semi-circular hollow portion 2a. Therefore, the gripping portions 22D, 22E, 22F, 22H, and 22I can be easily grasped while increasing the versatility of the handrail bodies 2D, 2E, 2F, 2H, and 2I in terms of hand size, etc.

[0074] For example, in the third modified example, the gripping portion 22D of the suspension body 2D is curved downward in an arch shape at a position below the semicircular center TB of the belt holding portion 21, as shown in Figure 13(A). Furthermore, the vertical distance t3 between the upper end portion 223D and the lower end portion 224D of the gripping portion 22D is formed to be constant in the left-right direction.

[0075] Furthermore, in the fourth modified example, the gripping portion 22E of the suspension hand body 2E is curved upward in an arch shape at a position below the semicircular center TB of the belt holding portion 21, as shown in Figure 13(B). Here, the upper end portion 223E is curved upward in an arch shape, and the lower end portion 224E is formed in a straight line. Also, the vertical distance t4 between the upper end portion 223E and the lower end portion 224E of the gripping portion 22E is maximized closer to the center in the left-right direction.

[0076] Furthermore, as shown in Figure 13(C), the gripping portion 22F of the fifth modified hanger body 2F is curved downward in an arch shape at a position below the semicircular center TB of the belt holding portion 21. Here, the upper end portion 223F is formed in a straight line, and the lower end portion 224F is formed in a downward curved shape. In addition, the vertical distance t5 between the upper end portion 223F and the lower end portion 224F of the gripping portion 22F is maximized closer to the center in the left-right direction.

[0077] Furthermore, in the sixth modified example, as shown in Figure 14(A), the gripping portion 22H of the suspension hand body 2H has an upper end 223H and a lower end 224H formed in a straight line horizontally, below the semicircular center TB of the belt holding portion 21. Also, the vertical distance t6 between the upper end 223H and the lower end 224H of the gripping portion 22H is formed to be constant in the left-right direction.

[0078] Furthermore, in the seventh modified example, as shown in Figure 14(B), the gripping portion 22I of the suspension body 2I has an upper end 223I that curves upward in an arch shape, and a lower end 224I that is formed in an arch shape downward, at a position below the semicircular center TB of the belt holding portion 21. In addition, the vertical distance t7 between the upper end 223I and the lower end 224I of the gripping portion 22I is maximized closer to the center in the left-right direction.

[0079] <Effects and Effects> As described in detail above, according to the vehicle suspension straps 10, 10B, 10C, 10D, 10E, 10F, 10G, 10H, and 10I of this embodiment, the suspension strap body 2, 2B, 2C, 2D, 2E, 2F, 2H, and 2I has a belt holding portion 21 which is formed in a semi-circular shape when viewed from the front, with a support shaft portion 211 that extends in the left-right direction and has the lower end of the suspension belt 1, 1G wound around it in the front-back direction, in the belt groove portion 212a of the upper central portion 212, and extends horizontally from both lower ends 213 of the belt holding portion 21. The handrails are equipped with gripping parts 22, 22B, 22C, 22D, 22E, 22F, 22H, and 22I that passengers JK grasp, and are formed in a semi-circular ring shape when viewed from the front. As a result, the left-right direction of the handrail bodies 2, 2B, 2C, 2D, 2E, 2F, 2H, and 2I coincides with the arrangement direction of the suspension belts 1 and 1G. Generally, passengers JK lined up along the arrangement direction of the suspension belts 1 and 1G can see the semi-circular ring hollow part 2a of the handrail bodies 2, 2B, 2C, 2D, 2E, 2F, 2H, and 2I from the front. Therefore, even when the vehicle SR shakes, the semi-circular ring hollow portion 2a of the handrail body 2, 2B, 2C, 2D, 2E, 2F, 2H, 2I is easily visible, and a finger can be quickly inserted into the semi-circular ring hollow portion 2a to securely grip the gripping portion 22, 22B, 22C, 22D, 22E, 22F, 22H, 22I of the handrail body 2, 2B, 2C, 2D, 2E, 2F, 22H, 22I.

[0080] Furthermore, since the gripping parts 22, 22B, 22C, 22D, 22E, 22F, 22H, and 22I that passengers JK grasp extend horizontally from both lower ends 213 of the belt holding part 21, a wide area for the gripping parts 22, 22B, 22C, 22D, 22E, 22F, 22H, and 22I that passengers JK grasp can be secured downwards, allowing even short passengers JK to stably grasp the handrail body 2, 2B, 2C, 2D, 2E, 2F, 2H, and 2I. Furthermore, since the lower ends of the suspension belts 1 and 1G are restricted by the edge of the belt groove 212a, positional displacement of the hand straps 2, 2B, 2C, 2D, 2E, 2F, 2H, and 2I relative to the suspension belts 1 and 1G can be avoided, and even when the vehicle SR shakes, passengers JK who are gripping the hand straps 2, 2B, 2C, 2D, 2E, 2F, 2H, and 2I can easily maintain their posture.

[0081] Furthermore, the belt holding portion 21 has a support shaft portion 211 that extends in the left-right direction and around the lower ends of the suspension belts 1 and 1G, and is located in the belt groove portion 212a of the upper central portion 212, and is formed in a semi-circular shape when viewed from the front. This allows for an expansion of the space for the semi-circular ring hollow portion 2a into which the passenger JK's fingers can be inserted, while effectively reducing the volume and weight of the belt holding portion 21 in the upper central portion 212 that is held by the lower ends of the suspension belts 1 and 1G. As a result, weight reduction and resource conservation can be promoted in the hand strap bodies 2, 2B, 2C, 2D, 2E, 2F, 2H, and 2I.

[0082] Furthermore, the gripping portions 22, 22B, 22C, 22D, 22E, 22F, 22H, and 22I are formed with an elongated cross-sectional shape in the vertical direction. The front contact surface 221 and the back contact surface 222, which the fingers contact on the front and back sides respectively, are bent or curved at an obtuse angle in a direction that causes the intermediate parts 221a and 222a in the vertical direction to bulge outward. As a result, the front contact surface 221 and the back contact surface 222 intersect at an acute angle at the upper position Q1 and the lower position Q2 of the gripping portions 22, 22B, 22C, 22D, 22E, 22F, 22H, and 22I, and bend or curve at an obtuse angle at the intermediate positions Q3 and Q4 in the vertical direction, respectively. Therefore, when passenger JK's thumb Y1 and other fingers (index finger Y2, middle finger Y3, ring finger Y4, little finger Y5) grasp the gripping parts 22, 22B, 22C, 22D, 22E, 22F, 22H, 22I of the handrail body 2, 2B, 2C, 2D, 2E, 2F, 22H, 22I, the upper front touches intersect at an acute angle with each other at the upper position Q1 of the gripping parts 22, 22B, 22C, 22D, 22E, 22F, 22H, 22I. Along the hand surface 221b and the upper back surface 222b, the second joint P2 between the middle phalanx K2 and the proximal phalanx K3 of the other fingers can be bent at an acute angle. Also, along the front surface 221 or back surface 222, which are bent or curved at an obtuse angle at intermediate vertical positions Q3 and Q4, the first joint P1 between the distal phalanx K1 and the middle phalanx K2 can be bent at an obtuse angle. Therefore, the bending angle β1 of the first joint P1 of the other fingers, which is difficult to bend, can be made larger than the bending angle β2 of the second joint P2, which is easy to bend, thus avoiding bending the first joint P1 to an unnatural angle of less than 90 degrees. As a result, when gripping the gripping parts 22, 22B, 22C, 22D, 22E, 22F, 22H, and 22I, excessive strain on the first joint P1 of the gripping finger can be avoided, allowing for a comfortable grip.

[0083] Therefore, according to this embodiment, it is possible to provide vehicle handles 10, 10B, 10C, 10D, 10E, 10F, 10G, 10H, 10I that allow for quick gripping of the handle bodies 2, 2B, 2C, 2D, 2E, 2F, 2H, 2I, have a wide gripping area, reduce the burden on the joints of the gripping fingers, make them easy to hold, and contribute to weight reduction and resource conservation of the handle bodies 2, 2B, 2C, 2D, 2E, 2F, 2H, 2I.

[0084] Furthermore, according to this embodiment, the belt holding portion 21 comprises an outer peripheral flange portion 21H extending in a semi-circular arc shape in the circumferential direction on the outer peripheral side, and a mountain-shaped inner peripheral rib portion 21R rising on the inner peripheral side of the outer peripheral flange portion 21H. Since the outer peripheral flange portion 21H and the inner peripheral rib portion 21R are formed in a cross-sectional shape that intersects in a T-shape, the bending strength in the direction normal to the semi-circular outer peripheral flange portion 21H can be efficiently reinforced with a small cross-sectional area by the mountain-shaped inner peripheral rib portion 21R. As a result, while ensuring the necessary bending strength in the suspension body 2, 2B, 2C, 2D, 2E, 2F, 2H, and 2I, further weight reduction and resource conservation can be achieved.

[0085] Furthermore, according to this embodiment, the outer peripheral flange portion 21H is formed such that the flange width ω(ω1, ω2) in the front-back direction gradually widens from the lower end portion 213 to the upper central portion 212 of the belt holding portion 21, and the front edge surface 21H1 and the back edge surface 21H2 of the outer peripheral flange portion 21H, and the front contact surface 221c and the lower part below the intermediate portions 221a and 222a of the gripping portions 22, 22B, 22C, 22D, 22E, 22F, 22H, and 22I Since the backing surface 222c and the other are connected on the same plane, the load of the passenger JK on the gripping parts 22, 22B, 22C, 22D, 22E, 2F, 2H, and 22I can be reliably transmitted to the suspension belts 1 and 1G via the belt holding part 21, which has increased rigidity due to the outer peripheral flange part 21H that gradually widens towards the top. Furthermore, by connecting the front edge surface 21H1 and the back edge surface 21H2 of the outer peripheral flange portion 21H, and the front contact surface 221c and the lower back contact surface 222c of the gripping portions 22, 22B, 22C, 22D, 22E, 22F, 22H, and 22I below the intermediate portions 221a and 222a, respectively, on the same plane, the sense of unity between the belt holding portion 21 and the gripping portions 22, 22B, 22C, 22D, 22E, 22F, 22H, and 22I is enhanced, improving the appearance, and in sudden situations, the lower end of the belt holding portion 21 can be easily gripped. As a result, further improvements in weight reduction, resource conservation, and convenience can be promoted for the hanger body 2, 2B, 2C, 2D, 2E, 2F, 2H, and 2I.

[0086] Furthermore, according to this embodiment, the inner circumferential rib portion 21R is formed such that the rib height d3 gradually increases from the lower end portion 213 to the upper central portion 212 of the belt holding portion 21. The inner circumferential end portion 21R1 of the inner circumferential rib portion 21R and the upper ends 223, 223D, 223E, 223F, 223H, 223I of the gripping portions 22, 22D, 22E, 22F, 22H, 22I are continuously connected with the same width ω3. This allows for weight reduction and resource conservation of the handrail bodies 2, 2D, 2E, 2F, 2H, 2I, while reliably transmitting the load of passengers JK onto the gripping portions 22, 22D, 22E, 22F, 22H, 22I to the suspension belts 1, 1G via the belt holding portion 21, whose rigidity is enhanced by the inner circumferential rib portion 21R, which gradually increases in rib height d3 towards the top. Furthermore, by continuously connecting the inner circumferential end portion 21R1 of the inner circumferential rib portion 21R and the upper ends 223, 223D, 223E, 223F, 223H, 223I of the gripping portions 22, 22D, 22E, 22F, 22H, 22I with the same width ω3, the sense of unity between the belt holding portion 21 and the gripping portions 22, 22D, 22E, 22F, 22H, 22I is enhanced, improving the appearance, and in sudden situations, the lower end of the belt holding portion 21 can be easily gripped. As a result, further improvements in weight reduction, resource conservation, and convenience can be promoted for the lifting hand body 2, 2D, 2E, 2F, 2H, 2I.

[0087] Furthermore, according to this embodiment, the gripping portions 22, 22D, 22E, 22F, and 22I are curved in an arch shape upward or downward at a position below the semicircular center TB of the belt holding portion 21. This ensures sufficient space for passenger JK to insert their fingers into the semicircular ring hollow portion 2a, while reducing the gap between the fingers and the gripping portions 22, 22D, 22E, 22F, and 22I that arises from differences in hand size, finger length, and thickness by gripping along the arch-shaped curved gripping portions 22, 22D, 22E, 22F, and 22I when the thumb Y1 and other fingers (index finger Y2, middle finger Y3, ring finger Y4, and little finger Y5) grip the gripping portions 22, 22D, 22E, 22F, and 22I, which arises from differences in hand size, finger length, and thickness. Therefore, the versatility of the hand strap bodies 2, 2D, 2E, 2F, and 2I in terms of hand size is increased, while the gripping parts 22, 22D, 22E, 22F, and 22I can be gripped even more easily.

[0088] Furthermore, according to this embodiment, the suspension belt 1G is divided into an upper suspension belt 12G supported by a belt support 3 and a lower suspension belt 11G wound around the pivot 211 of the hand strap bodies 2, 2B, 2C, 2D, 2E, 2F, 2H, 2I. The upper suspension belt 12G and the lower suspension belt 11G are connected by a belt connector 5 that allows the lower suspension belt 11G to rotate horizontally relative to the upper suspension belt 12G. Therefore, even if the length of the suspension belt 1G is short and it is difficult to rotate the hand strap bodies 2, 2B, 2C, 2D, 2E, 2F, 2H, 2I from a direction that coincides with the arrangement direction of the suspension belt 1G to a different direction, the orientation (left-right direction) of the grasped hand strap bodies 2, 2B, 2C, 2D, 2E, 2F, 2H, 2I can be changed via the belt connector 5 according to the passenger JK's preference. Therefore, for example, in a crowded train, passengers facing different directions can each grasp the handrails 2, 2B, 2C, 2D, 2E, 2F, 2H, and 2I in a position that is comfortable for them.

[0089] Furthermore, according to this embodiment, the belt connector 5 includes an upper connecting portion 51 connected to the upper suspension belt 12G, a lower connecting portion 52 connected to the lower suspension belt 11G, a middle connecting portion 53 that connects the upper connecting portion 51 and the lower connecting portion 52 so as to be rotatable horizontally, and a biasing member that is locked to the upper connecting portion 51 and the lower connecting portion 52 and biases the upper connecting portion 51 and the lower connecting portion 52 in a direction in which the left-right direction of the suspension body 2, 2B, 2C, 2D, 2E, 2F, 2H, 2I coincides with the arrangement direction of the suspension belt 1G. Because it is equipped with 56, even if the orientation (left-right direction) of the grasped hand strap bodies 2, 2B, 2C, 2D, 2E, 2F, 2H, 2I is changed according to the passenger JK's preference, when the passenger JK releases the hand strap bodies 2, 2B, 2C, 2D, 2E, 2F, 2H, 2I and moves, the biasing member 56 automatically returns the orientation (left-right direction) of the hand strap bodies 2, 2B, 2C, 2D, 2E, 2F, 2H, 2I to a direction that matches the arrangement direction of the suspension belt 1G. Therefore, the orientation (left-right direction) of the hand strap bodies 2, 2B, 2C, 2D, 2E, 2F, 2H, 2I can be quickly returned to a state where the next passenger can grasp them.
