Abstract

PURPOSE:To enable reliable holding of a shaft member, in a system where the shaft members arranged at the opposite sides of a tonneau board are fitted in the holding groove for a holding member, by forming the holding groove with rigid material wider than the diameter of the shaft member while arranging a metallic springboard in said groove. CONSTITUTION:In a system whre a shaft member (tonneau board shaft) 4 secured to the opposite side sections at the cabin side of a tonneau board 3 is fitted in a holding groove 13 of a holding member (tonneau board holder) 11 secured to the opposite sides of a luggage room to support the tonneau board 3, the holding groove 13 is formed by the supporting walls 14A, 14B of rigid material molded integrally with the base section 12 from resin such as nylon 6. The gap between the supporting walls 14A, 14B is formed slightly larger than the diameter of the tonneau board shaft 4. A metallic springboard 15 facing against one supporting wall 14A is provided in the holding groove 13 and inserted into a hole section 18 at the lower end of the supporting wall 14A to fix the leg 17 by tighening a screw 24.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a mounting structure for a tonneau board that covers a luggage room of a vehicle.

[Conventional technology]

FIGS. 4 to 6 show a conventional tonneau board mounting structure. In FIG. A shaft member (tonneboard shaft) 4 is fixed to both sides of the tonneau board 3 on the inside side of the vehicle, and a holding member (tonneboard holder) 6 is fixed to the parcel side 5 in the luggage room 2. The tonneau board holder 6 is molded from resin and has a base portion 7 to be fixed to the vehicle body and a holding portion 8 having a substantially U-shaped cross section and integrally formed with the base portion. The holding portion 8 is indicated by arrow A in FIG.
, can be bent in direction B, and its elastic force rotatably holds the tonneau board shaft 4 fitted in the holding groove 9 (see, for example, Japanese Utility Model Application No. 59-118741).

Therefore, when the back door 1 is opened, the toy board 3 is opened about the tonneau board shaft 4 by the connecting member 10 such as a string.

[Problem that the invention seeks to solve]

However, in such a conventional tonneau board mounting structure, since the holding part of the tonneau board holder is molded from an elastic resin, there is a problem in that the holding part deforms at high temperatures and the holding force decreases. In addition, the holding part is integrally molded with resin, and both rising parts forming a U-shaped cross section can be bent and deformed, so a large load from the rear seat etc. is applied to the tonneau board shaft fitted in the holding groove. When this happens, the tonneau board shaft may come off from the holding groove due to the bending deformation of the holding part.

Therefore, an object of the present invention is to ensure the holding state of the tonneau board shaft holding member (1) and the tonneau port holder (1).

[Means for solving problems]

+iIn order to achieve the above objectives and solve the conventional problems,
In the present invention, the holding groove of the holding member is formed of a rigid body having a width wider than the diameter of the shaft member, and a metal leaf spring for holding the shaft member is provided in the holding groove.

[Effect]

According to the present invention, the shaft member of the tonneau board is always stably held by a metal leaf spring that is less affected by temperature. Moreover, since the support walls on both sides of the holding groove are rigid bodies, the shaft member will not come off from the holding groove even if a large load is applied to the shaft member.

〔Example〕

1 to 3 show an example of the mounting structure of the tonneau board according to the present invention. In FIG. ), 11 is a holding member (tonnoboard holder) that holds the tonneau board shaft 4. The tonneau board holder 11 has a base part 12 and a holding groove 13 formed on the base part 12. The holding groove 13 consists of rigid support walls 14A and 14B that are integrally molded with the base portion 12 from resin such as nylon 6.
The gap between the tonneau board shirts is formed to be slightly larger than the diameter of the tonneau board shirt l-4. In the holding groove 13, there is one support wall 1.
A metal leaf spring 15 facing 4A is provided.

The support wall 14A is provided on the rear side of the vehicle relative to the leaf spring 15, and triangular ribs 16 are provided on both rear sides thereof to reinforce the support qx4A. Further, a hole 18 through which the leg 17 of the leaf spring 15 is inserted is formed at the lower end of the support wall 14A. Furthermore, a protective portion 19 that prevents the metal leaf spring 15 from being exposed is integrally formed on both sides of the leaf spring 15 on both sides (on the side facing the seat). On the other hand, as shown in FIG.
A slope 21 for positioning that can be engaged with an engagement hole 20 formed at the tip of the reflex 1 of No. 5 is formed, and a screw hole 22 is provided in the slope 21. Further, a retaining portion 23 having a cross-section shape that engages with the parcel side 5 is formed on the front back surface of the base portion 12.

Therefore, in order to fix this tonneau board holder 11 to the vehicle body, the temporary spring 15 is inserted through the gap formed between the first part 19 and the leg 17 of the leaf spring 15 is fixed to the support wall 14A.
The engaging part 23 of the tonneau board holder 11 is inserted into the hole 18 at the lower end and is engaged with the engaging hole 20 at the tip of the reflex 1 and the slope 21 of the base part 2.
At the same time, the leaf spring 15 and the base portion 12 in the engaged state are fixed to the parcel side 5 with screws 24-c. On the other hand, the tonneau board shaft 4 is thus fitted into the leaf spring 13 while pushing the leaf spring 15 apart. The tonneau board shaft 4 fitted in this manner is biased toward the rear of the vehicle by the leaf spring 15 while being placed on the four portions 25 formed in a continuous portion with both the support walls 14A and 14B. On the other hand, the biasing force applied by the leaf spring 15 is received by the support wall 14A. Therefore, the tonneau board shaft 4
is always urged by the leaf spring 15 within the holding groove 13 and its back and forth movement is restricted. Further, since the leaf spring 15 has a substantially S-shaped cross section, movement of the tonneau board shaft 4 in the vertical direction is also restricted.

Therefore, according to this tonneau board mounting structure, since the tonneau board shaft 4 is always biased toward the support wall 14A by the metal plate spring 15, the holding force does not weaken at high temperatures, and the support wall 14A Since it is firmly supported by the ribs 16, it will not bend and deform even if a large load is applied to the tonneau board shaft 4 from the rear seat, etc., and the tonneau board shaft 4 will not come off from the retaining groove 13. Since an engagement hole 20 is provided at the tip of the leg 17 of the plate I5, it is easy to position the leaf spring 15, and the holder and plate before being attached to the vehicle body. It can be integrated with the spring without using any special parts. Furthermore, the force application point of the leaf spring 15 and the leg 17
Because there is a relatively large distance between the tip and the fixed part,
The leaf spring 15 is flexible and has a large elastic force. In the above embodiment, the tonneau board shaft 4 was pressed against the support wall 14A by the leaf spring 15, but a U-shaped spring was used to press the tonneau board shaft 4 against both the support walls 14A.
, 14B may be provided with a gap n■.

〔Effect of the invention〕

As explained above, according to the present invention, the shaft member running around the tonneau board is normally held by a metal leaf spring whose holding force changes little due to temperature, and even when an excessive input is applied, the holding groove formed by the rigid support wall can be held securely. Therefore, the shaft member will not come off from the holding member even at high temperatures or when a large front ball is applied.
