DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heater panel for a vehicle, which is arranged on the floor of a vehicle and heats the floor with a heater.

[0002]

2. Description of the Related Art In general, when heating the interior of a train car, the temperature near the floor becomes lowest due to the convection of air. Therefore, a heating device for a vehicle has been considered in which heating inside the vehicle is performed by a heater arranged on the vehicle floor so as to increase the temperature near the floor surface, for example, as shown in FIGS. 5 and 6. As described above, the heater 11 is inserted into the groove of the keystone plate 8 for reinforcing the floor strength placed on the underframe 2 of the vehicle 1.
And a floor material 5 is laid on a keystone plate 8 via a metal plate 9 (Japanese Patent Application Laid-Open No. 57-58552). The underframe 2 shown in FIG. 6 to which a wheel block (not shown) is attached is formed in a lattice shape by vertically and horizontally combining lattice members 2a made of U-shaped members.

[0003] However, in the above conventional example,
Since the heaters 11 are spaced at intervals determined by the groove intervals of the keystone plate 8 for securing the strength of the vehicle floor, a low-temperature portion (heater 1) where the heaters 11 are not disposed is provided.
(The temperature is lower than that of the high-temperature portion immediately above the first portion), and uniform floor heating cannot be performed. Therefore, it is conceivable that the heater panel 3 is placed on the keystone plate 8 and the floor material 5 is laid on the heater panel 3. However, there is a problem that the vehicle floor becomes higher by the thickness of the heater panel 3. Was.

In view of the above points, the present inventors have proposed a vehicle heater panel as shown in FIG.
No. 76 proposed. The vehicle heater panel 3 shown in FIG. 7 includes a heater 1 near the inner surface of an upper plate 10a of a housing 10 having a height substantially equal to that of a keystone plate.
1 is uniformly arranged, and a heat insulating material 12 is filled between the heater 11 and the lower plate 10b of the housing 10,
Vertical support member 1 for securing required strength of vehicle floor
Numeral 3 is provided between the upper and lower plates 10a and 10b, and can be directly mounted on the underframe 2 without using a keystone plate. The reference numeral 10c denotes a peripheral wall of the housing 10, which also serves as a support member in the vertical direction around the housing.

[0005]

As described above, the vehicle heater panel 3 shown in FIG. 7 has many advantages as compared with the conventional example shown in FIGS. In order to reduce the weight, the vertical support members 13 for securing the strength may be thinned out. However, as shown in FIG. 7, since the vertical support members 13 are arranged in parallel at equal intervals, as a floor, There is a problem that the strength cannot be secured.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicle heater panel capable of reducing the weight while securing the strength as a floor. It is in.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention has a heater disposed close to an inner surface of an upper plate of a housing, and a heater disposed between an upper plate and a lower plate of the housing. In a vehicle heater panel in which a vertical support member is provided and a heat insulating material is filled between an upper plate and a lower plate of a housing, a plurality of upper and lower support members are juxtaposed between an upper plate and a lower plate of the housing, The juxtaposed interval is made dense at the center of the housing and sparse at the periphery.

[0008]

According to the present invention, a plurality of upper and lower support members are arranged between the upper plate and the lower plate of the housing.
Since this juxtaposed interval is made dense in the center of the housing and sparse in the periphery, after reducing the number of upper and lower support members to be used, it is furthest away from the housing support portion of the underframe.
To secure strong strength at the center of the housing, which is the most flexible, and close to the underframe housing support.
In the peripheral portion of the housing that is hardly bent, the strength corresponding to that can be secured, and the weight as well as the floor can be secured.

[0009]

The present invention will be described below with reference to examples. (Embodiment 1) FIGS. 1 and 2 show this embodiment. The configuration of this embodiment is basically the same as that of FIG.
The spacing of the vertical support members 13 provided between the upper plate 10a and the lower plate 10b of the housing 10
It is set so as to be dense and sparse from the center of 0 to both sides. Therefore, even if the number of the vertically supporting members 13 to be used is smaller than that in the case of FIG.
Conversely, the strength of the peripheral portion where the load applied is small is set to an appropriate strength corresponding to the applied load, and the necessary strength for the floor can be secured. Moreover, the weight of the heater panel 3 is reduced by the decrease in the number of the vertical support members 13.

The mounting of the vehicle heater panel 3 is performed by using a mounting bracket 16 which is engaged with a step 15 formed on a peripheral portion of the upper surface of the housing 10.
6 is screwed to a projecting wall 17 projecting from the lattice member 2b with mounting screws 18.
Can be reliably fixed while absorbing the thermal expansion in the lateral direction, the upper surface of the heater panel 3 can be flush with the mounting bracket, and the positioning can be easily performed by the protruding wall 17. I have.

(Embodiment 2) In this embodiment, as shown in FIGS. 3 and 4, between a top plate 10a and a bottom plate 10b of a housing 10 arranged so as to close a window opening of an underframe 2. The vertical support members 13a and 13b are arranged in two layers so as to be perpendicular to each other, and the arrangement interval is dense at the center of the housing 10 and sparse at the periphery, as in the first embodiment. The weight is reduced while securing the strength of the floor.

Since the mounting of the vehicle heater panel 3 is the same as that of the first embodiment, the configuration and description thereof are omitted.

[0013]

As described above, according to the present invention, a heater is provided near an inner surface of an upper plate of a housing, and a vertical support member is provided between an upper plate and a lower plate of the housing. In a vehicle heater panel in which a heat insulating material is filled between lower plates, a plurality of upper and lower support members are juxtaposed between an upper plate and a lower plate of a housing, and the juxtaposed intervals are made dense at a central portion of the housing, Since it is made sparse around the periphery, the number of upper and lower support members to be used can be reduced, and moreover, the strength corresponding to the load applied to each part of the housing can be obtained, while securing the strength as the floor There is an effect that the weight can be reduced.
