Description

  The present invention relates to a railcar stool, and more particularly, to a railcar stool suitable for eliminating individual differences in passenger thermal sensation.

  Conventionally, in a railway vehicle, various devices have been made in order to make the temperature distribution in the passenger cabin uniform. However, passengers on the window side may feel hot due to radiant heat from the blinds, and there is a problem that individual differences in thermal feeling cannot be corrected.

  Therefore, the conditioned air sent from the air conditioner placed under the floor of the vehicle body is raised up to the air conditioning duct outlet located near the floor or the waist of the side structure, and cool air or hot air is blown out from the vicinity of the passengers. Alternatively, a method has been devised in which warm air reaches the passengers. Furthermore, a method of eliminating an individual difference in thermal sensation by providing an air passage inside the seat so that conditioned air is blown to each passenger is considered (Patent Document 1).

  Although the above-mentioned conventional technology considers that the conditioned air is blown out from a fixed seat and passengers can easily adjust the air volume individually, the seat that can rotate 180 degrees and reverse the direction is blown. The layout of the road was not taken into consideration at all, and the passengers individually did not consider the air volume adjustment.

In addition, high-grade seats such as green cars recline the seat cushion and backrest and sink the seat surface, so the entire seat moves, so it is actually impossible to secure a ventilation path in the moving part of the seat There was a problem.

Therefore, in a stool that can be rotated 180 degrees and reversed in direction, there is a problem to be solved in that conditioned air can be blown individually from the stool at any rotational position.
It is an object of the present invention to provide a railcar seat that can easily adjust the air flow and the wind direction individually for a passenger so that individual differences in thermal sensation can be corrected in the seat that can be rotated 180 degrees and reverse in direction. It is to provide.

  In order to achieve the above object, an air duct that discharges conditioned air at a point-symmetrical position with respect to a rotation center axis with respect to the pedestal of the stool is provided in a stool for a railway vehicle that can rotate 180 degrees and reverse its direction. It is characterized by that.

  According to this stool for a railway vehicle, conditioned air is discharged through an air duct that is an air passage provided in the stool at any rotational position that can be rotated 180 degrees and reversed in direction, and arrives on the stool. Passengers can use conditioned air individually according to their own thermal sensation.

  In this railcar seat, the air duct is provided in the outer stool of the seat, and an auxiliary duct that guides conditioned air to the air duct can be provided on the footrest. Since the air duct is provided inside the outer periphery of the seat width direction that is point-symmetric with respect to the rotation center axis of the seat, when the seat is rotated by 180 degrees and reversed, the seat is facing in any direction The mating surfaces of the air duct provided in the rotating part of the seat and the auxiliary duct provided on the stationary platform on the fixed side are in the same position, so that conditioned air can be sent from the auxiliary duct to the air duct.

  Further, in this railcar seat, a wind direction grill is provided at the outlet of the air duct where the air duct opens at the outer sleeve, and a wind direction means provided in the air duct is further provided. -The ventilation switch to cut can be provided in the armrest part in the said outer sleeve. The wind direction grill provided at the outlet of the air duct can adjust the wind direction of the conditioned air toward the passenger sitting on the stool from the upper surface of the armrest of the stool. In addition, by providing a blower switch for the blower means provided in the air duct on the armrest upper surface, it becomes easier for passengers to operate the blower switch to turn on and off the blower means. Obtainable.

  As described above, according to the present invention, regardless of the direction of the stool that can be rotated 180 degrees and reversed in direction, the passenger can individually cool air or warm air through the air duct provided on the stool. Since it can be obtained, the individual difference with respect to a thermal feeling can be eliminated.

  Embodiments of a railcar seat according to the present invention will be described below with reference to the drawings. FIG. 1 is a schematic plan view of a two-seat stool as an embodiment of a stool for a railway vehicle according to the present invention. FIG. 2 is a left side view of the stool shown in FIG. FIG. 3 is a right side view of the seat shown in FIG. FIG. 4 is a schematic front view of the seat, showing the main cross section of each duct.

  In FIG. 1, a two-seat stool shown as an embodiment of a railway vehicle stool includes seat cushions 1 a and 1 b on which two passengers can sit, backrests 2 a and 2 b as backrests, and cushions 1 a and 1 b. Outer sleeves (armrests and one piece) 3a, 3b arranged on the outside, one center sleeve (shared left and right with the armrests and one piece) 4 arranged in the middle of the cushions 1a, 1b, and cushions 1a, It has footrest levers 5a and 5b arranged on the inner front side of 1b. Wind direction grills 20a and 20b are provided on the armrests of the outer sleeves 3a and 3b, and are provided on the armrests of the outer sleeves 3a and 3b in an air duct, which will be described later, adjacent to the wind direction grilles 20a and 20b. Air blowing switches 21a and 21b for the air blowing means to be used are provided.

  As shown in FIGS. 2 and 3, air ducts 22a and 22b are provided inside the outer sleeves 3a and 3b. The air ducts 22a and 22b incorporate axial flow fans 23a and 23b as blowing means for sucking conditioned air from below. The axial fans 23a and 23b are turned on and off by operating the blower switches 21a and 21b. The stool is kept at an appropriate height between the floor and the floor surface by the leg stand 6. Further, the postures of the footrests 8a and 8b can be changed by operating the footrest levers 5a and 5b. Tables 9a and 9b for passengers in the rear seats are provided on the backs of the backrests 2a and 2b.

  In order to guide the conditioned air from the air conditioner to the air ducts 22a and 22b, the auxiliary duct 30 is provided fixed to the leg base 6. Filters 31 a and 31 b are installed at the outlet of the auxiliary duct 30 to prevent rectification of the blown air and entry of foreign matter.

  The installation positions of the air ducts 22a and 22b provided inside the outer sleeves 3a and 3b are point-symmetrical with respect to the rotation center axis with respect to the leg base 6 on the seat. Therefore, even if the two-seat stool is rotated 180 degrees and the direction is reversed, the arrangement and direction of the stool on the window side and the passage side are reversed, and the air ducts 22a and 22b and the auxiliary duct replaced by the reversal are reversed. The relative position of 30 does not change.

  Next, the flow of conditioned air supplied from the air conditioner will be described in detail with reference to FIG. The conditioned air blown from the air conditioner suspended under the floor of the vehicle is supplied to the air distribution duct 32 in the floor passing between the side wall 41 and the floor, and then passed between the side panel 40 and the interior material. It is guided to the duct 33 and is blown out into the vehicle from the blowing grill 34 under the load shelf.

  In this embodiment, in addition to the conventional flexible duct 33, an auxiliary duct 30 is provided on the seat base 6, and conditioned air is supplied from the floor air distribution duct 32. The auxiliary duct 30 is composed of a duct that is raised from the floor on the lower side of the window-side stool, and a duct that is led to the lower side of the stool on the opposite side (passage side). Is also arranged at a point-symmetrical position with respect to the rotation center axis with respect to the leg base 6. The conditioned air is supplied from the respective ducts to the air ducts 22a and 22b provided on both outer sleeves.

  In FIG. 4, the stool is rotatably supported on the leg base 6 by the rotation device 10, and the pedal 7 is unlocked by stepping on the pedal 7. When the two-seat stool is rotated 180 degrees in the unlocked state, the arrangement of the stool on the window side and the passage side is reversed, but the air ducts 22a and 22b and the auxiliary duct 30 that have been reversed are replaced. The relative position does not change. Since the stool rotates 180 degrees, a certain gap is provided between the mating surfaces of the auxiliary duct 30 and the air ducts 22a and 22b. This gap is determined in consideration of the assembly error of the seat.

  Axial fan 23a. In a state where 23b is stopped, the conditioned air blown out from the auxiliary duct 30 leaks somewhat from the gap provided on the mating surface with the air ducts 22a and 22b, thereby cooling or heating the feet of the passengers. In the state where the axial fans 23a and 23b are rotating, the conditioned air blown out from the auxiliary duct is sucked into the air ducts 22a and 22b and blown out from the wind direction grills 20a and 20b provided on the upper surfaces of the outer sleeves 3a and 3b. If the passenger feels hot during cooling, the passenger can turn on the air blowing switches 21a and 21b and adjust the angle of the wind direction grills 20a and 20b to obtain a cool feeling. The same applies to heating.

  All the conditioned air discharged into the vehicle is mixed with the air in the vehicle to reach a comfortable temperature, sucked into the return duct 35 in the floor from the suction port 36 provided on the floor, and returned to the air conditioner. . In addition, it is preferable to install a filter for preventing entry of foreign matter at the inlet and outlet of the air ducts 22a and 22b.

  According to the present embodiment described above, the passenger can directly obtain conditioned air even if the seat is rotated 180 degrees, so that individual differences in thermal sensation can be individually corrected.
