Description

  The present invention relates to a cover structure.

  Some large trucks intended for long-distance transportation have a nap bedroom immediately after the seat in the driver's cab, but the high roof car is equipped with a wind deflector made of FRP on the upper surface of the cab. It has been proposed that the bedroom is expanded in the vertical direction by utilizing the rear part of the internal space of the wind deflector, and the upper and lower beds are provided here.

  The rear end of the upper bed is hinged to the back panel of the cab so that it can tilt, and when it is not needed, the front end is flipped up and folded along the back panel. Thus, it is considered that the front end portion can be supported by being suspended from the ceiling portion by a belt.

  When the front end of the upper bed is suspended and supported from the ceiling by a belt, a belt is attached to the front end of the bed, and a buckle provided at the tip of the belt is attached to the ceiling of the cab. It has been studied to engage the provided tongue plate in the same manner as the seat belt detaching mechanism.

  However, when such a structure is adopted, the tongue plate protrudes downward from the ceiling of the cab, and the passenger inadvertently raises his head in the cab and hits his head against the tongue plate. There was a fear of it.

  The present invention has been made in view of the above circumstances, and it is intended to provide a cover structure that can prevent the interference between the passenger's head and the tongue plate on the ceiling and ensure the safety of the passenger in the cab. Objective.

  The present invention is a cover structure for covering a ceiling penetration portion of a tongue plate protruding downward so that a buckle of a connection object can be engaged with a ceiling portion of a driver's cab, with respect to the general surface of the ceiling portion A tongue plate that has a recess shape that is recessed upward and that has a cover body that is formed with a slit through which the tongue plate extends so that the tongue plate protrudes into the recess space. In order to avoid interference with the 165 mm diameter sphere headform, overhanging portions are formed on both the left and right sides of the cover body so as to project to a position lower than the tongue plate.

  Thus, since the tongue plate fits in the hollow space that is recessed upward from the general surface of the ceiling part, the tongue plate and the cover body are arranged so as to protrude greatly downward from the general surface of the ceiling part. The possibility of interference between these and the head of the passenger is greatly reduced.

  Also, even if the occupant inadvertently raises his head in the cab and hits the cover body, the 165 mm diameter headform corresponding to the shape of the average occupant's head will not interfere with the tongue plate. Since the overhanging part is formed, the passenger's head hits the overhanging part of the cover body lower than the tongue plate, and the head hits the tongue plate in the hollow space sandwiched between the overhanging parts Is prevented in advance.

  Furthermore, when the present invention is implemented more specifically, the slit is formed so as to have a required clearance around the tongue plate, the slit is covered over a wide range on the upper surface side of the cover body, and the cross section of the tongue plate is formed. It is preferable that a shielding sheet provided with an insertion port that substantially matches the shape at a position corresponding to the slit is slidable with respect to the upper surface of the cover body.

  In this way, even if a slight deviation occurs in the positional relationship between the cover main body and the tongue plate due to the variation in assembly, the deviation is absorbed by sliding the shielding sheet on the upper surface side of the cover main body. Since it is possible to continue closing the gap between the slit and the tongue plate, it is possible to keep the appearance of the ceiling penetrating portion of the tongue plate favorable.

  In addition, especially when the roof panel is made of a light transmissive material, there is a possibility that light transmitted through the roof panel may leak out from the gap between the slit and the tongue plate. In addition, if the gap between the slit and the tongue plate is surely closed by the shielding sheet, it is possible to avoid such a fear of light leakage.

  Further, in the present invention, it is preferable that the ceiling trim is inserted and fixed to either one of the front and rear sides of the cover body, and the other is preferably configured to be fastened to the ceiling portion by fastening with a fastener. In this way, it is possible to easily attach the cover body simply by inserting and fixing the ceiling trim to either one of the front and rear sides of the cover body and fastening the other side with the fastener.

  According to the cover structure of the present invention described above, various excellent effects as described below can be obtained.

  (I) According to the invention described in claim 1 of the present invention, the tongue plate can be accommodated in a hollow space that is recessed upward from the general surface of the ceiling portion, and the tongue plate and the cover main body are the general surface of the ceiling portion. Therefore, the possibility of interference between these and the occupant's head can be greatly reduced. Even if it is lifted and hits the cover body, the occupant's head hits the protruding part of the cover body lower than the tongue plate, and the head hits the tongue plate in the hollow space sandwiched between the protruding parts. Therefore, it is possible to ensure the safety of passengers in the cab.

  (II) According to the invention described in claim 2 of the present invention, even if there is a slight shift in the positional relationship between the cover body and the tongue plate due to the variation in assembly, the shift sheet is shielded on the upper surface side of the cover body. The sliding sheet can be absorbed and the gap between the slit plate and the tongue plate can be kept closed by the shielding sheet, so that the appearance of the through-ceiling portion of the tongue plate can be kept good, especially the roof panel is light transmissive. In the case of being made of a material, it is possible to avoid the possibility that light transmitted through the roof panel leaks from the gap between the slit and the tongue plate.

  (III) According to the invention described in claim 3 of the present invention, the cover body can be simply attached by inserting and fixing the ceiling trim to either one of the front and rear sides of the cover body and fastening the other side with a fastener. Since the attachment can be performed, it is possible to greatly simplify the attachment work of the cover main body, which is a burden due to the upward work, and the labor burden on the operator can be remarkably reduced.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 to 5 show an example of an embodiment for carrying out the present invention, which relates to a high roof vehicle having an FRP wind deflector mounted on the upper surface of a cab, among upper and lower bunk beds provided in a bedroom immediately after a seat. The case where it applies to the mechanism which suspends and supports the bed of the upper stage from the ceiling part of a cab is illustrated.

  As shown in FIG. 1, a tongue plate 5 protrudes downward on the ceiling 4 of the cab 3 so that the buckle 2 of the belt 1 extending from the front end of the upper bed (not shown) can be engaged. The tongue plate 5 is supported by the bracket 6 between the ceiling trim 7 of the ceiling portion 4 and the wind deflector 8 (roof panel).

  The ceiling penetrating portion of the tongue plate 5 is covered with a cover body 9 (see FIGS. 2 and 3), and the cover body 9 is recessed upward with respect to the general surface of the ceiling portion 4. A slit 11 is formed which has a hollow shape and allows the tongue plate 5 to protrude into the hollow space 10 (see FIG. 1).

  Moreover, as shown in FIG. 4 (FIG. 5 is a cross-sectional view taken along arrows IV-IV in FIG. 1), a tongue plate 5 projecting from the slit 11 of the cover body 9 to the indoor side and a headform 12 having a 165 mm diameter sphere. Overhang portions 13 are formed on both the left and right sides of the cover body 9 so as to avoid interference, and project to a position lower than the tongue plate 5.

  Here, the head form 12 having a sphere diameter of 165 mm is a model of a human head generally used when performing an impact test or the like on an upper vehicle interior structure, and has an average human head shape. It is treated as equivalent.

  Further, in this embodiment, the slit 11 is formed to be large so as to have a required clearance around the tongue plate 5, covers the slit 11 in a wide range on the upper surface side of the cover body 9, and the tongue A shielding sheet 14 provided with an insertion port 14a substantially matching the cross-sectional shape of the plate 5 at a position corresponding to the slit 11 is provided so as to be slidable with respect to the upper surface of the cover body 9.

  That is, as shown in FIGS. 2, 3, and 5 (FIG. 5 is a cross-sectional view taken along line VV in FIG. 3), upward projections 15 are integrally formed at four locations around the slit 11 on the upper surface of the cover body 9. Therefore, the shielding sheet 14 is arranged on the upper surface side of the cover body 9 so that the protrusions 15 penetrate the long holes 16 at the four corners of the shielding sheet 14, and a pair of protrusions 15 arranged side by side. Are arranged so that the front and rear portions of the shielding sheet 14 can be pressed from the upper surface, and the front and rear removal prevention sheets 17 are attached to the projections 15 with push nuts 18 attached thereto. It is fixed (when the push nut 18 is sufficiently larger than the long hole 16, the removal preventing sheet 17 may be omitted).

  Further, on both sides of the rear side of the upper surface of the cover body 9, there are provided engaging claws 19 that rise upward and then bend and extend in an L-shape toward the rear. A ceiling trim 7 is inserted between the upper surface of the cover 9 and the rear portion of the cover body 9 can be fixed.

  On the other hand, a fastening hole 21 is opened on both sides of the front side of the cover body 9 so that a retainer 20 (fastener) can be passed therethrough, and the retainer 20 is fitted to face each fastening hole 21. A tool 22 is supported by a bracket 23, and the retainer 20 is pushed into the fitting tool 22 through the fastening hole 21 from the recessed space 10 side and fastened to fasten the front part of the cover body 9 to the ceiling part. 4 can be fixed.

  Thus, when the cover structure that covers the ceiling penetrating portion of the tongue plate 5 is configured in this way, the tongue plate 5 is accommodated in the hollow space 10 that is recessed upward from the general surface of the ceiling portion 4. And it is not necessary to take an arrangement in which the cover main body 9 protrudes greatly downward from the general surface of the ceiling portion 4, and the possibility of interference between these and the passenger's head is greatly reduced.

  In the unlikely event that an occupant inadvertently raises his / her head in the cab 3 and hits the cover body 9, the head form 12 having a 165 mm diameter corresponding to the shape of the average occupant's head is Since the overhanging portion 13 is formed so as not to interfere with 5, the head of the occupant hits the overhanging portion 13 of the cover body 9 lower than the tongue plate 5 and is a depression sandwiched between the overhanging portions 13. It is possible to prevent the head from hitting the tongue plate 5 in the space 10.

  Further, even if a slight deviation occurs in the positional relationship between the cover main body 9 and the tongue plate 5 due to the variation in assembly, the deviation is absorbed by sliding the shielding sheet 14 on the upper surface side of the cover main body 9. Therefore, it is possible to keep closing the gap between the slit 11 and the tongue plate 5, so that the appearance of the ceiling penetration portion of the tongue plate 5 can be kept good.

  In particular, as in the present embodiment, when the roof panel is made of a light transmitting material such as an FRP wind deflector 8, the light transmitted through the roof panel is formed between the slit 11 and the tongue plate 5. Although there is a possibility of leaking from the gap, as described above, if the gap between the slit 11 and the tongue plate 5 is surely blocked by the shielding sheet 14, such a case It is possible to avoid worrying about light leakage.

  Further, in the present embodiment, the ceiling trim 7 is inserted between the engaging claw 19 and the upper surface of the cover body 9 to fix the rear portion of the cover body 9, and the retainer 20 is fastened to the fastening hole 21 from the recessed space 10 side. The cover main body 9 can be simply attached simply by fixing the front portion of the cover main body 9 to the ceiling portion 4 by pushing it into the fitting tool 22 and fastening it.

  Therefore, according to the embodiment, the tongue plate 5 can be accommodated in the hollow space 10 that is recessed upward from the general surface of the ceiling portion 4, and the tongue plate 5 and the cover main body 9 are larger than the general surface of the ceiling portion 4. Since there is no need to use an arrangement that projects downward, it is possible to greatly reduce the possibility of interference between these and the occupant's head. Even if the cover body 9 is raised, the head of the occupant hits the overhanging portion 13 of the cover body 9 lower than the tongue plate 5, and the tongue plate in the hollow space 10 sandwiched by the overhanging portion 13. Since it is possible to prevent the head from hitting 5, it is possible to ensure the safety of the passenger in the cab 3.

  Further, even if a slight deviation occurs in the positional relationship between the cover main body 9 and the tongue plate 5 due to the variation in assembly, the deviation is absorbed by sliding the shielding sheet 14 on the upper surface side of the cover main body 9. As a result, the gap between the slit 11 and the tongue plate 5 can be closed continuously, so that the appearance of the through-ceiling portion of the tongue plate 5 can be kept good, and the light transmitted through the wind deflector 8 constituting the roof panel is slit. The possibility of leakage from the gap between the tongue plate 5 and the tongue plate 5 can also be avoided.

  Further, the ceiling trim 7 is inserted between the engaging claw 19 and the upper surface of the cover main body 9 to fix the rear portion of the cover main body 9, and the retainer 20 is passed through the fastening hole 21 from the recessed space 10 side to the fitting tool. Since the cover main body 9 can be easily attached simply by fixing the front portion of the cover main body 9 to the ceiling portion 4 by being pushed into 22 and being fastened, the cover main body is burdensome due to the upward work. 9 can be greatly simplified, and the labor burden on the operator can be significantly reduced.

  The cover structure of the present invention is not limited to the above-described embodiment. In the embodiments of FIGS. 1 to 5, the upper and lower two-tier beds provided in the bedroom immediately after the seat of the high roof car. Although the case where it applies to the mechanism which suspends and supports the bed of the upper stage from the ceiling part is illustrated, the ceiling penetration part of the tongue plate for engaging the buckle of various connection objects other than this is illustrated. It is possible to apply as a cover structure to be covered, the sliding mechanism of the shielding sheet is not limited to the illustrated example, and bolts or screws other than the retainer may be used for the fastener, etc. Of course, various modifications can be made without departing from the scope of the present invention.
