Description

  The present invention relates to a structure of a suspended leather installed in a passenger cabin of a vehicle such as a train, a bus, and a ship.

    Conventionally, the structure of a suspended leather is such that a single leather portion with its upper end locked to a suspended leather holding member installed on the ceiling portion of a vehicle or the like is suspended, and a single gripping portion (a so-called “lung leather” is provided at the lower end of the leather portion. The user normally holds the stability of the body by gripping the grip portion with one hand.

    Suspension leather as a safety device for standing passengers to maintain the stability of the body against shaking of a vehicle etc. is inherently easy to maintain the most stable posture by gripping each suspension leather with both hands. Although it is highly safe, one passenger cannot occupy two hanging leathers at the time of congestion, and one passenger's hand is often closed with baggage, etc. It is used in. In fact, although passengers often use a single strap with both hands, the existing strap (grip) is designed for use with one hand, so it can be used with both hands. Is unsuitable.

    On the other hand, due to the recent rapid declining birthrate and aging population in Japan, the proportion of elderly people among public transport passengers is also increasing. Public transport such as trains and buses have priority seats for senior citizens, and when seats are full, manners such as giving passengers to senior citizens have become established. Depending on the situation, the majority of passengers in the car are aged. In addition, as the number of elderly workers increases, the proportion of elderly people in passengers increases even during busy hours such as commuting hours. The number of passengers is expected to increase further in the future.

On the other hand, in order to improve the safety and comfort of the suspended leather user, as described in, for example, Patent Document 1 (Japanese Patent Laid-Open No. 8-290734), there is elasticity in the middle of the leather portion of the suspended leather. A structure that relaxes the influence of the shaking of the vehicle on the human body by providing a body, a structure that regulates the shaking in the traveling direction of the vehicle by improving the shape of the leather part, such as Patent Document 2 (Japanese Patent Laid-Open No. 2000-289512), etc. However, these structures are based on the premise that the passengers can hold the suspended leather securely with one hand.
Japanese Patent Laid-Open No. 8-7290734 Japanese Patent Laid-Open No. 2000-289512

    However, it is relatively easy for passengers up to the middle age to hold a leather strap with one hand to maintain the balance of the body. In many cases, there is a high risk of falling and injured if the hand unexpectedly moves away from the suspended leather due to sudden braking of the vehicle or heavy shaking during congestion.

    In order to prevent this danger, a solution is to make the suspended leather grippable with both hands. Even if the grip strength with only one hand is insufficient, if you can grip the hanging leather with both hands, you can withstand a considerable degree of sudden braking and large shaking of the vehicle, and hand fatigue is also distributed to both hands, This is because it is possible to use suspended leather for a long time. The present invention is based on such an idea, and by improving the structure of the individual suspension leather, without reducing the total number of passengers who can use the suspension leather in the cabin of a vehicle or the like that has a certain upper limit on the number of standing passengers. The present invention provides a suspended leather structure that allows a passenger to grip a suspended leather with both hands even in a full state, and that can improve safety and reduce fatigue.

    In addition, when a passenger is carrying baggage, one hand is closed, so the suspended leather cannot be grasped by both hands. Traditionally, there are hanging shelves to hold baggage in the passenger compartment of railway vehicles, but they are too expensive for elderly people because they have to be installed at a rather high position because they are located above the seats. Many common buses are not equipped with hanging racks in the first place. Also, placing baggage on the floor of your feet is not realistic because it has great resistance in terms of psychology and crime prevention and increases the risk of your feet when it is crowded. On the other hand, it is difficult to keep the baggage at the same time with the hand that holds the suspended leather. Therefore, it can be a solution if a structure is provided in which the baggage is suspended and held on the suspended leather itself that is held by both passengers and the baggage can be easily attached and detached.

As means for solving the problems of the present invention, as described in claim 1, the suspension is suspended by individual suspension leathers without changing the total number of suspension leathers installed in the vehicle or the like. In this structure, the number of grips (rings) is increased from one to two. In addition, as described in claim 4 , by providing a structure (hook) that can suspend baggage at a part of the gripping part, even when there is baggage, It is possible to manage within the reach. Here, it is conceivable that the hook structure is provided with a notch in a part of the grip portion so that the grip portion itself forms a hook structure. However, in this structure, the strength of the grip portion is reduced, so the grip portion itself A high-strength material is used as the material, or a method of reinforcing the core by inserting a core of steel or the like inside a gripping portion that is usually made of resin. In addition, in order to avoid the above-described reduction in strength, the entire gripping portion may be formed into a shape in which the hook structure is separately projected at the lower portion of the gripping portion, instead of forming a notch in the gripping portion itself. Conceivable. The invention of claim 4 can be applied not only to the structure of a suspended leather having two gripping portions described in claims 1 to 3 of the present application but also to a gripping portion of a suspended leather having only one conventional gripping portion. .

The invention described in claim 1 has a structure in which two holding portions are provided on one hanging leather, and a single leather portion (hereinafter referred to as “hung”) that is suspended by a hanging leather holding member installed on the ceiling portion in the vehicle. The lower end of two leather parts (hereinafter referred to as “lower leather parts”), each of which is provided with a bifurcated branch structure in the middle of “the upper leather part.” One holding part is suspended from each other.

In the invention described in claim 1 , the reason for providing the bifurcated branch structure in the middle of the leather part is that if the two leather parts are directly locked to the suspended leather holding member and the gripping parts are suspended, The overall length of the leather part from the locking part to the gripping part becomes longer, the freedom of movement of the two gripping parts gripped with both hands is excessively increased, and on the contrary, the body stability is maintained against shaking of the vehicle etc. Because it becomes difficult. For shaking, it is empirically known that the state in which the distance between the gripping parts gripped by both hands is about the shoulder width of the user is the easiest to maintain the stability of the body, and the lower leather branched into two branches This is because, by appropriately setting the length of the portion, it is possible to appropriately set the interval between the grip portions during use.

On the other hand, in the devices described in claim 2 and claim 3 , the height of the two gripping parts from the floor is the same height when used with both hands of the suspended leather, and when used with one hand or when not used. Is provided with a mechanism for moving the gripping part B above the gripping part back. The reason for providing such a mechanism is that if the two gripping parts of the first and second members are always fixed at the same height, it is only necessary to use the first gripping part for those who use only one hand, and the second gripping part becomes an obstacle. In addition, when the entire suspended leather swings in response to the shaking of the vehicle when not in use, the gripping parts may collide with each other due to the vibration of the vehicle, and unnecessary sounds may be generated. Other than that, it is considered appropriate to make the suspension heights of the two grip portions different so as not to interfere with each other.

Specifically, the invention described in claim 2 is provided with a pulling mechanism in the bifurcated branch structure that automatically lifts the suspension position of the gripping part second upward when the gripping part second is not used. It is said. As such a lifting mechanism, a winding mechanism that uses the repulsive force of the elastic body is built in, and the suspension position of the gripping part 2 is automatically adjusted by winding the lower leather part 2 that suspends the gripping part 2 in the lifting mechanism. Built-in pull-in mechanism that also uses the repulsive force of the elastic body, and pulls the lower leather part B that suspends the grip part B into the pull-up mechanism so that the position of the grip part B is suspended. It is structured to pull up automatically. A metal spring is suitable as the elastic body, but is not limited thereto.

Further, in the invention described in claim 3 , as the bifurcated structure, a support member having an asymmetrical weight distribution with the lower end portion as a fulcrum can be rolled on the lower end portion of the upper leather portion depending from the suspended leather holding member. The upper end of the lower leather part that suspends the gripping part A and B is attached to the supporting points provided in the vicinity of both end parts of the supporting member so as to be able to roll. The support member has an asymmetrical weight distribution (e.g., the side on which the gripping part back is suspended is heavier than the side on which the gripping part back is suspended) around the fulcrum. It rolls 90 degrees automatically like a seesaw with the fulcrum as the center, with the side down and the gripping part B side up. As a result, the supporting point of the gripping part A, the fulcrum, and the supporting point of the gripping part B are arranged vertically from the bottom, and the gripping part B moves directly above the gripping part A. On the other hand, when the suspended leather is used with both hands, the supporting member rolls in the opposite direction 90 degrees around the fulcrum by pulling the gripping part B moving upward with one hand, and accordingly the gripping part The upper moves while rolling and can be gripped with the other hand at the same height as the gripping part B. As a result, the user can grip the two gripping portions with both hands at an appropriate interval.

As described above, according to the suspended leather having the structure according to the present invention, the passenger of the vehicle can grasp the grasping portion of the suspended leather with both hands. The stability of the body can be maintained more easily, and the risk of injury due to falling can be reduced. In addition, when the suspended leather according to claim 2 or 3 is used with one hand, the grip portion on the side that is not used moves above the grip portion to be used, so that it does not obstruct the use. It has the effect that it can be used comfortably and safely regardless of other passengers.
Furthermore, by applying the structure of the holding part of the suspended leather according to claim 4 , the passenger can manage the baggage without placing it on the floor or the like while holding the suspended leather with both hands while riding.

    In addition, although it is not an effect based on the original solution problem of the present invention, as long as the passenger holds the hanging leather shown in the present invention with both hands, one hand can eliminate the state of “playing”, which has become a social problem in recent years. A secondary effect is also conceivable, which is useful for self-defense in order to prevent innocent passengers from being suspected of perpetration by molester victims in a molested accusation case on a crowded train.

    Below, although a plurality of embodiments for carrying out the present invention are disclosed, these are examples, and implementation of the present invention is not limited to these embodiments.

    FIG. 1 is a side view and a front view showing the structure of a “simple bifurcated” hanging leather according to a first embodiment of the present invention. Reference numeral 11 denotes a suspended leather holding member installed on the ceiling of the vehicle interior, and reference numerals 12 and 13 denote an upper part and a second part of the suspended leather, respectively. The gripping part A and B 12 (13) are respectively suspended by a lower leather part A and B 14 (15), and the upper end of the lower leather part A and B 14 (15) is connected to the lower end of the upper leather part 16 by a bifurcated branch structure 17, The upper leather part 16 is locked at its upper end to a suspended leather holding member 11 installed on the ceiling part in the vehicle. The bifurcated branch structure 17 has a structure in which a rotating shaft that penetrates the connecting end portions of the upper and lower leather parts (14, 15, 16) is supported by a pair of bearings provided on the inner surface of the bifurcated branch structure. Since the rotary shaft can freely roll, the passenger can hold the grips 12 and 13 with both hands and support the body, and can arbitrarily hold the gap between the grips.

    FIG. 2 is a side view and a front view showing the structure of the “winding type” hanging leather according to the second embodiment of the present invention. Reference numeral 11 denotes a suspended leather holding member installed on the ceiling of the vehicle interior, and reference numerals 12 and 13 denote an upper part and a second part of the suspended leather, respectively. The gripping part upper 12 is directly latched and suspended by the leather holding member 11 by the leather part upper 21, and the leather part end 22 for hanging the gripping part end 13 is connected to the upper part of the leather part upper 21. The winding mechanism 23 is fixed. The inside of the winding mechanism 23 is coaxially connected by a winding unit 24 that winds the leather part 22 and the winding unit 24 and a rotating shaft 26, and rotates the winding unit 24 using the repulsive force of an elastic body. A driving unit 25 to be driven and a bearing that supports a winding shaft 24 and a rotating shaft 26 penetrating the driving unit 25 at both ends are configured. In this embodiment, when the passenger pulls down the gripping part B13 with one hand to hold the gripping part A B 12 (13) at the same height with both hands, the leather part B 22 wound around the winding part 24 is used. When the gripping part B13 is lowered and the gripping part 13 is lowered to the same height as the gripping part 12, the full length of the leather part B is extended and the lowering is stopped. Further, when the passenger removes his / her hand from the gripping part end 13, the winding part 24 rotates and winds the leather part end 22 by the restoring force of the elastic body in the driving part 25, so that the gripping part end 13 also moves upward. .

    FIG. 3 is a side view and a front view showing the structure of the “slide type” hanging leather according to the third embodiment of the present invention. Reference numeral 11 denotes a suspended leather holding member installed on the ceiling of the vehicle interior, and reference numerals 12 and 13 denote an upper part and a second part of the suspended leather, respectively. The gripping part upper is directly engaged with the suspended leather holding member 11 by the leather part upper 31 and is suspended, and the leather part upper 31 is connected to the leather part 32 for suspending the gripping part 13. Is fixed. Inside the lifting mechanism 33, the upper end of the leather part 32 is fixed to the other end of the elastic body 34 having one end fixed to the lower part of the lifting mechanism 36. In this embodiment, when the passenger pulls down the gripping part B13 with one hand to hold the gripping part B12 (13) at the same height with both hands, the elastic body 34 extends and the hand is released from the gripping part B13. The leather part 32 is pulled into the lifting mechanism 33 by the restoring contraction force of the elastic body 34, and the gripping part 13 also moves upward. A leather side stopper 35 is installed at the tip of the leather part 32 fixed to the elastic body 34. When the grip part 13 is pulled down, the leather part side stopper 35 is located above the lifting mechanism 36. By hitting the mechanism side stopper 36 provided in the inside, the gripping part B13 is restrained from being lowered below the same height as the gripping part A12.

  FIG. 4 shows the structure of a “seesaw type” hanging leather according to the fourth embodiment of the present invention in a front view (when left or used with one hand), a side view, and a front view (when used with both hands). is there. Reference numeral 11 denotes a suspended leather holding member installed on the ceiling of the vehicle interior, reference numerals 12 and 13 denote upper and lower gripping portions of the suspended leather, and reference numeral 42 denotes a suspended leather holding member 11 by the upper leather portion 41 via a fulcrum 43. It is a support member that suspends the gripping part A and B 12 (13) through the support point A 44 and the support point B 45 while being suspended. The support member 42 has a heavy asymmetrical weight distribution on the side of the support point 44 that suspends the gripping part A12 and is light on the side of the support point B45 that suspends the gripping part B13. In this embodiment, when the passenger pulls down the gripping part B13 with one hand so as to grip the gripping part A with the same height with both hands, the support member 42 rolls around the fulcrum 43 as a support point. When the gripper part 12 suspended from the upper part 44 rises and is released from the gripper part 13, the gripper part 12 descends due to its own weight that is unevenly distributed on the support point base 44 side of the support member 42. Moves above the vertical line of the gripper shell 12.

5 and 6 show an embodiment of the structure of the holding part of the suspended leather described in the invention of claim 4 . The gripping portion shown in FIG. 5 has a notch structure in a part of a normal gripping portion having a substantially annular structure, and the notch portion is subjected to a smooth shape and surface treatment. Passengers can hang and hold their baggage, for example, the handle of a paper bag with a handle or the belt strap of a handbag, by hanging it on the notch, and easily remove it from the notch when getting off the vehicle. You can also. Moreover, the said holding part shown in FIG. 6 has a hook structure in one side of a holding part lower part, and can hang and hold baggage similarly. By applying the gripping part having the notch structure or the hook structure to the suspended leather having the structure of the first to fourth embodiments, the passenger can hang the baggage on the gripping part at the same time while holding the gripping part with both hands. It is always possible to keep it within your own field of view. However, when baggage is suspended from the gripping part, depending on the length of the handle or belt strap, the baggage main body is located at the height of the face of the passenger sitting on the seat in front of the suspended leather and swings due to the shaking of the vehicle Since there is a risk that the main body of the baggage may hit the passenger's face, it is necessary to limit the size of the baggage to be suspended.

    The structure of the suspended leather in a vehicle that has two gripping parts A and B enables the elderly with weak gripping force to grip the gripping part with both hands, ensuring the stability of the body against sudden braking and shaking of the vehicle. It is effective in preventing accidents involving falling, and has the potential to be applied to the in-vehicle safety structure of public transportation systems that responds to future aging societies.
