Description

  The present invention relates to a luggage rack structure for a railway vehicle.

  In railcars, the racks of luggage racks composed of a plurality of arm-shaped load shelves and the shelves supported by them are viewed from below for the prevention of forgotten items such as luggage, crime prevention, and lighting. There is a case where a structure that can be used is required.

  However, when forming a shelf board with a wire mesh or a pipe, if an article placed on the shelf board is small, it may fall through the mesh of the wire mesh or a gap between the pipes.

  Therefore, a glass plate, a transparent resin plate, or the like may be used as the shelf plate. In that case, the luggage shelf is configured as a structure that supports a shelf plate such as a glass plate with a frame member, but the step between the upper surface of the shelf plate and the upper surface of the frame member is so that the luggage can be stably supported. It is desired to be as small as possible.

  Therefore, an unnecessary portion of the extruded material of the aluminum alloy is removed by cutting to form a luggage shelf body having an opening, and glass or plastic made on the stepped portion around the opening. There has been proposed one in which a luggage shelf is placed and fixed by adhesion (for example, see Patent Document 1).

JP 2006-256520 A (paragraph 0012)

  As in the structure described in Patent Document 1, if an unnecessary portion is removed by cutting from an extruded material of an aluminum alloy to form a luggage shelf body having an opening, the weight can be reduced. There is a waste that cutting waste is generated by cutting. Further, in addition to the material cost, a processing cost is required, which causes an increase in cost.

  An object of the present invention is to provide a luggage rack structure for a railway vehicle that saves resources by eliminating machining such as cutting, reduces costs, and is easy to assemble.

  The invention of claim 1 is a luggage shelf structure of a railway vehicle comprising a plurality of cargo shelf receptacles and a cargo shelf board supported by them, and the cargo shelf board is uniform over the entire length of the luggage rack. It comprises a long front and rear frame member having a cross section, and a shelf member supported by being sandwiched between them by a cushioning material, and the shelf plate on the upper side of the shelf receiver The front and rear frame members are fixed.

Therefore, cutting waste is not generated, resource saving is achieved, and manufacturing costs are reduced. Further, since the shelf board member is only sandwiched between the front and rear frame members, the assembly can be easily performed. Moreover, the manufacturing error at the time of production of a shelf board member can be absorbed by adding a buffer material between a shelf board member and a frame member (front side and rear side frame member). Furthermore, a tempered glass plate that is difficult to process, such as providing a screw hole for screwing, may be employed as the shelf plate member.

  According to a second aspect of the present invention, each of the front and rear frame members has a fitting groove that extends in the longitudinal direction of the luggage shelf and fits with the front and rear edges of the shelf board member. It is desirable that the front side and rear side frame members of the load shelf board are screwed to the upper side.

  In this way, it is possible to eliminate the parts that hold the shelf board member, and in addition to simplifying the structure, it is possible to reduce the number of parts, which is advantageous in reducing costs. In addition, since the front and rear frame members of the load shelf board are fixed to the upper side of the load shelf receiver, the load shelf board does not move in the longitudinal direction of the load shelf board, and only conceals the end of the load shelf board. This is also advantageous in terms of reducing the number of parts.

  According to a third aspect of the present invention, the load shelf support includes a shelf support main body portion that extends in a substantially horizontal direction, and an attachment portion that extends upward from the rear end of the shelf support main body portion. A vertical wall configured to be arranged at an intermediate position and both end positions in the direction, and the shelf receivers located at both ends extend upward to the outer side of the shelf support main body part and conceal the ends of the shelf board It can be set as the structure by which the part is integrally formed.

  In this way, since the load shelf support (vertical wall portion) also has a component for concealing the end portion of the load shelf plate, it is advantageous in reducing the number of components.

  According to a fourth aspect of the present invention, the cargo rack receiver is disposed at a first cargo rack receiver disposed at an intermediate position in the longitudinal direction of the cargo rack plate and at both end positions in the longitudinal direction of the cargo rack plate. A through hole is formed in the front end portion of the first load shelf receiver, and a fitting hole is formed in the front end portion of the second load shelf receiver. A front bar member is inserted through the through hole of the load rack receiver, each end of the front bar member is fitted into the fitting hole of the second load rack holder, and the first and second load rack receivers It is desirable that the cargo rack supports are coupled to each other by the front bar member by being screwed to the front bar member.

  If it does in this way, since load shelf supports are couple | bonded by the front bar member with a simple structure, rigidity can be improved.

  According to a fifth aspect of the present invention, it is desirable that the rear frame member is integrally formed with a closing plate portion that extends upward along the mounting portion of the load shelf support.

  In this way, since the closing plate portion is integrally formed as a part of the rear frame member, the closing plate that prevents the luggage on the shelf from being sucked out through the window portion is a separate part. This is advantageous in reducing the number of parts. In addition, assembly work can be saved.

  In the present invention, since the shelf member is sandwiched between the front and rear frame members and both the frame members are fixed to the load shelf receiver, machining for forming the opening is not performed, so that the cutting waste Can save resources and save resources. Therefore, the manufacturing cost is greatly reduced. In addition, since the shelf plate member is only sandwiched between the front and rear frame members, it is easy to assemble, and in addition, a tempered glass that is difficult to process such as providing a screw hole for screwing. A board can also be employed as the shelf board member.

  The first cargo rack receiver 2A is arranged at an intermediate position in the vehicle longitudinal direction of the cargo rack plate 3 and supports the intermediate portion of the cargo rack plate 3 from the lower side. It is arrange | positioned at the both ends position of the vehicle longitudinal direction of the board 3, and supports the edge part of the cargo shelf board 3. As shown in FIG. Each of the first and second cargo rack receivers 2A, 2B is L-shaped, extends in a substantially horizontal direction, and supports the rack shelf board 2A from the lower side, and has a rectangular cross-section shelf receiving body 2Aa, 2Ba, There are mounting portions 2Ab and 2Bb extending upward from the rear ends of the shelf receiving main body portions 2Aa and 2Ba, and the vicinity of the upper end portions of the mounting portions 2Ab and 2Bb are connected to the screws 21 via the cargo rack mounting locations 12A, 12B and 12C. The side structure 11 is fixed. The fixed position is an upper position than the window portion 11 a formed in the side structure 11. In addition, “extending in a substantially horizontal direction” includes a case where the shelf receiving main body portions 2Aa and 2Ba are inclined and inclined upward by about 5 ° to 10 ° so that the luggage does not fall from the front side.

  The shelf board 3 is sandwiched between the long and hollow front and rear frame members 4 and 5 having a uniform cross section over the entire length in the longitudinal direction of the luggage shelf 1 and cushioning materials 6A and 6B therebetween. And a transparent shelf member 7 (for example, a glass plate) that is supported. The front and rear frame members 4, 5 have fitting grooves 4 a, 5 a that extend in the longitudinal direction of the luggage shelf 1 (corresponding to the longitudinal direction of the vehicle) and fit with the front and rear edges of the shelf board member 7.

  The front and rear edge portions of the shelf board member 7 are fitted into the fitting grooves 4a and 5a to form the loading shelf board 3, and the frame members 4 and 5 of the loading shelf board 3 are the shelf receiving body portions 2Aa of the loading shelf receivers 2A and 2B. , 2Ba (screws) are fixed to the screws 8A and 8B (screws), so that it is not necessary to use a part that holds the shelf plate member 7 so as not to be detached from the frame members 4 and 5. Since the front and rear frame members 4 and 5 are merely placed on the first and second cargo rack receivers 2A and 2B, it is not necessary to provide notches in the longitudinal direction on both of the cargo rack receivers 2A and 2B. Since there is no need for assembly during assembly, it is advantageous in improving accuracy and quality.

  Further, the rear frame member 5 is integrally formed with a closing plate portion 5B extending upward along the attachment portions 2Ab and 2Bb from the rear edge of the shelf receiving body portion 5A that supports the shelf plate member 7. And this closing board part 5B is extended from the upper edge part of the window part 11a to the upper part, and the lightweight luggage (for example, a newspaper, a magazine, etc.) on the shelf board 3 passes through the window part 11a at the time of opening of the window part 11a. It is designed to prevent it from being sucked out. The closing plate portion 5B is fixed to the mounting portions 2Ab and 2Bb (screws) of the first and second cargo rack receivers 2A and 2B with screws 8C. By forming the closing plate portion 5B as a part of the rear frame member 5 in this way, it is not necessary to provide the closing plate as a separate part.

  As shown in FIG. 6 (a), the second load shelf receiver 2B located at both ends of the first and second load rack receivers 2A and 2B is arranged at the outer side of the shelf receiving body 2Ba having a rectangular cross section. A vertical wall 2Baa extending upward is integrally formed. Further, as shown in FIG. 3, the upper front edge of the vertical wall portion 2Baa is inclined forward and the rear edge is connected to the lower portion of the attachment portion 2Bb. And by this vertical wall part 2Baa, the edge part of the cargo shelf board 3 is concealed, and the edge part of the cargo shelf board 3 cannot be visually recognized from the outside. As described above, since the end portion of the load shelf board 3 can be concealed by the vertical wall portion 2Baa of the second load shelf receiver 2B, it is necessary to separately provide a part for concealing the end portion of the load shelf board 3. Disappears.

  Moreover, there is a possibility that both frame members 4 and 5 are screwed with screws 8A and 8B on the upper side of the shelf receiving body portions 2Aa and 2Ba of the shelf receivers 2A and 2B, and the shelf board 3 moves in the longitudinal direction thereof. Since there is no, it is only necessary to conceal the end portion of the load shelf board 3 by the vertical wall portion 2Baa of the second load shelf receiver 2B. In addition, it is not necessary to perform the alignment between the end portion of the shelf member 7 of the load shelf plate 3 and the inner surface of the vertical wall portion 2Baa, and a packing 13 or the like is provided in the gap between them as necessary. (See FIG. 6A), the gap can be easily filled.

  In this way, the supporting part of the shelf board member 7 is only the front and rear frame members 4 and 5, and the necessary cushioning material is reduced by reducing the contact parts with other members (for example, metal) of the shelf board member 7. The number of points can be reduced. Also in this respect, resource saving can be achieved and the manufacturing cost can be reduced.

  The shelf receiving body portions 2Aa and 2Ba of the first and second load shelf receivers 2A and 2B have mounting holes 2a and 2b formed at the tip portions, and the front bar member 14 is loaded using the mounting holes 2a and 2b. It is attached to the shelf supports 2A and 2B. Each of the shelf holders 2A, 2B and the front bar member 14 are screwed with screws 15. As a result, the first and second cargo rack receivers 2A and 2B are coupled to each other via the front bar member 14, thereby increasing the rigidity. The mounting hole 2a of the first cargo rack receiver 2A is a through hole through which the front bar member 14 is inserted, but the mounting hole 2b of the second cargo rack receiver 2B is not a through hole but a front bar member. 14 is a fitting hole into which each end of 14 is fitted.

  In addition, the two second shelf receivers 2B located at both ends are attached to the shelf receiver body 2Ba having a longer length than the three first shelf receivers 2A located between them. Thus, the protruding amount of the front end portion of the second cargo rack receiver 2B into the vehicle compartment is larger than that of the first cargo rack receiver 2A.

  And the upper end part of the grip bar 23 extended to an up-down direction is connected to the part of the front end side rather than the position where the front bar member 14 is attached of the 2nd load shelf receiver 2B. That is, between the second load rack receivers 2B, as shown in FIGS. 7A and 7B, the joint member 24 is fixed to the front bar member 14 by the two screws 25 and extends in the vertical direction. The upper end portion of the grip rod 23 is fitted into the cylindrical portion 24 a of the joint member 24 and is fixed by a screw 26.

  If comprised as mentioned above, the load shelf board 3 will interpose the elongate front side and rear side frame members 4 and 5 which have a uniform cross section over the full length of a luggage shelf, and cushioning material 6A, 6B between them. And the shelf members 7 that are sandwiched and supported, and the frame members 4 and 5 are fixed to the upper side of the first and second load shelf receivers 2A and 2B with screws 8A and 8B. In order to attach the plate member 7, it is not necessary to perform machining as in the conventional structure. Therefore, waste such as generation of cutting waste can be eliminated, resource saving can be achieved, and the manufacturing cost can be greatly reduced. Further, since the front and rear edges of the shelf board member 7 are fitted into the fitting grooves 4a and 5a of the front and rear frame members 4 and 5, and are sandwiched and attached between the frame members 4 and 5, Assembly can be performed easily.

  In addition to the embodiment described above, the present invention can be implemented with the following modifications.

  (i) As shown in FIG. 6A, not only the vertical wall portion 2Baa conceals the end portion of the shelf board member 7, but also the fitting concave portion in which the end portion of the shelf board 3 is fitted into the vertical wall portion. It is also possible to form

  (ii) By increasing the width of the front side frame member, it is possible to ensure the required rigidity and to omit the front bar member.
