Description

  The present invention relates to a loading platform seat mounting apparatus for a freight vehicle, and more particularly, to a mounting apparatus that can cover a loading platform with a simple operation and prevents rainwater from entering the loading platform.

  For example, when a cargo is being mailed in a freight vehicle, if there is rain, the cargo loaded on the loading platform gets wet with rain water, and if a powdery or granular cargo is loaded, the cargo may be scattered if there is a gust or strong wind. Therefore, the cargo on the loading platform is covered with a sheet. However, if the occupant manually puts a sheet on the cargo and fixes it with a rope or rubber band, the operation is very troublesome.

  Therefore, a horizontal winding shaft is provided at the front end of the loading platform, the sheet is wound around the winding shaft, and the winding shaft is urged by a spring member in the winding direction to unwind the sheet from the winding shaft. There has been proposed a seat mounting device that covers cargo (Patent Document 1, Patent Document 2).

  Also, a seat mounting device in which a horizontal J-shaped guide rail is attached to the rear wall of the passenger compartment, a slider is slidably fitted to the guide rail, a bone member is connected to the slider, and a seat is supported on the bone member. Has also been proposed (Patent Document 3).

Japanese Patent Laid-Open No. 08-58466 JP 2002-326533 A Japanese Patent Laid-Open No. 2004-175140

  However, in the seat mounting apparatus described in Patent Documents 1 and 2, there is a gap between the winding shaft and the rear wall surface of the passenger compartment, and rainwater may enter the cargo bed from this gap and wet the cargo.

  In addition, in the seat mounting device described in Patent Document 3, the bone member is bundled and positioned at the end of the guide rail so as to be along the load carrier wall surface. On the other hand, the bone member is unfolded and covered with the seat. Handling is troublesome.

  In view of such problems, it is an object of the present invention to provide a loading platform seat mounting device for a freight vehicle that can cover a loading platform with a simple operation and that rainwater does not enter the loading platform. To do.

  In view of the above, the loading platform seat mounting device for a freight vehicle according to the present invention is a seat mounting device for mounting a sheet covering the cargo platform above the loading platform to the vehicle body, and a retaining portion is formed continuously or intermittently at the front end over the entire length. A sheet that covers the upper part of the cargo bed, and whose both side edges and rear edge are locked to the side wall of the cargo bed, either directly or by ropes, and has a substantially cross-sectional front and almost П-shaped, front part of the cargo bed A sheet insertion groove having a groove width that can be inserted through the main body portion of the sheet, but cannot be inserted through the retaining portion of the sheet, is formed over the entire length of the horizontal side portion of the front surface that is substantially П-shaped. One or both of the left and right vertical sides of the П-shape are formed with a groove width that allows insertion of the sheet retaining portion in communication with the above-mentioned sheet insertion groove, and covers the loading platform with the main body portion of the sheet. Sometimes A holder that holds the front end of the vehicle and a water stop member that covers and attaches between the horizontal side of the holder and the vehicle body at the front end of the loading platform, and guides rainwater that travels through the vehicle body at the upper front end of the loading platform onto the main body portion of the seat And.

  One of the features of the present invention is that a frontal П-shaped holder is attached to the front end of the loading platform, and a sheet retaining portion is inserted into a set groove having a wide groove width on the vertical side portion of the П-shaped holder. The front end portion of the sheet is held by sliding into the sheet insertion groove having a narrow groove width, and the upper portion of the loading platform is covered with the main body portion of the sheet.

  This makes it possible to hold the front end of the seat by a simple operation of setting the slide retaining portion on the holder and sliding it, and then pulling the main body of the seat backward to cover the upper part of the loading platform, As in the seat mounting device described in Patent Document 3, a complicated operation of covering the seat after the bundled bone members are developed along the guide rail is unnecessary.

  Further, since the space between the holder and the vehicle body is covered with a water stop member, rainwater does not enter the cargo bed unlike the seat mounting devices described in Patent Documents 1 and 2. Further, in the seat mounting device described in Patent Document 3, it is necessary to connect the bone member and the front end portion of the seat with high sealing properties in order to prevent rainwater from entering, but in the present invention, the front end portion of the seat is connected. Since it is held by the holder, high sealing performance at the front end of the sheet can be easily ensured.

  The material of the holder is not particularly limited as long as the holder has a substantially cylindrical cross section, has a substantially П-shaped front surface, and can hold the retaining portion of the sheet. For example, the holder can be manufactured using a metal material or a plastic material.

  In addition, the sheet insertion groove of the holder needs to be directed to the rear in order to draw out the main body part of the sheet and cover the upper part of the loading platform, but the set groove only needs to be able to insert the retaining part of the sheet. The direction, for example, the rear side may be directed. However, it is not preferable that the front end of the seat rises due to a strong wind from the front while the freight vehicle is traveling, and it is necessary to prevent this. Therefore, it is preferable that the set groove of the holder is directed obliquely rearward or laterally of the vehicle body.

  The material of the sheet is not particularly limited as long as it can cover the cargo above the loading platform, and a vinyl sheet or a cloth sheet can be used.

  In addition, the shape of the sheet retaining portion is not particularly limited as long as it is a size that cannot be inserted into the sheet insertion groove of the holder, but considering the fact that the sheet is inserted into the set groove and then slid to the sheet insertion groove, the horizontal position of the holder It is preferable that the shape matches the cross-sectional shape of the side portion.

  The retaining portion of the sheet can be formed by winding a rope at the front end of the sheet. In this case, if the both ends of the rope are locked to the side wall of the loading platform, the front end of the sheet can be reliably held.

  When rainwater or the like accumulates on the sheet, the sheet sags downward due to the weight of rainwater, so it is preferable to provide a sheet receiving member. That is, the front end portion of the telescopic sheet receiving member is pivotally supported on the holder or the front body of the loading platform, and the rear end portion of the sheet receiving member is supported on the rear outer wall side of the loading platform, and the main body portion of the seat pulled out from the holder is supported. It is preferable to receive.

  The sheet receiving member can be composed of, for example, a plurality of hollow rods, and the material thereof is not particularly limited, and can be manufactured from a metal material or a plastic material.
