Yes. A spacer 7 for receiving a load applied to the luggage floor board 6 is interposed between the flange 5 a of the clamp 5 and the lower surface of the luggage floor board 6. A conventional example of a luggage floor structure for storing a spare tire 4 in a luggage room 2 of a vehicle is described in detail in Patent Document 1.

Japanese Utility Model Publication No.59-89778

  As described above, the luggage floor structure in the conventional luggage room 2 is provided with the luggage floor board 6 that covers the spare tire 4. The lower surface of the luggage floor board 6 receives a load from the luggage floor board 6. However, if the spare tire 4 has a dimensional difference due to a difference in specifications, it is necessary to change the dimension of the spacer 7 and a plurality of spacers 7 having different dimensions are required. It has been pointed out that there is an inconvenience that the cost increases due to an increase in mold costs and a rise in mold costs.

  The present invention has been made in view of such circumstances, and in a luggage floor structure in a luggage room of a vehicle, even if a dimensional difference due to a specification difference occurs in a spare tire, a single spacer is reversed and used to An object of the present invention is to provide a luggage floor structure for a vehicle that can stably support a luggage floor board at a low cost by always maintaining the board mounting height position constant.

  To achieve the above object, according to the present invention, a spare tire is stored in a recess for storing a spare tire in a luggage floor panel in a luggage room of a vehicle, and the spare tire is fixed by a clamp, and then the upper surface of the flange of the clamp is fixed. A luggage floor structure of a vehicle in which a luggage floor board is detachably attached to a floor panel via a spacer, and a pressing protrusion for pressing the upper surface of the spacer is formed on the lower surface side of the luggage floor board. On the other hand, the spacer is formed with annular projections on the front and back surfaces of the spacer body, the outside of the annular projection is a projection receiving surface that receives the pressing projection on the luggage floor board side, and the inside of the annular projection is abutted against the clamp flange. Set the spacer as a contact surface for the clamp so that it can be reversed, and equidistant from both projection receiving surfaces. The distance from the center line to the clamp contact surface on the one surface side and the distance from the clamp contact surface on the other surface side are made different from each other with reference to the center line that bisects the spacer body along the thickness direction. Therefore, by changing the distance from the projection receiving surface to the clamp contact surface in the normal posture where the front and back of the spacer are reversed and in the reversed posture, the spacer is reversed and used for spare tires of different specifications. The height position of the projection receiving surface and the mounting height position of the luggage floor board are kept constant.

  Here, the luggage room of the vehicle can be applied not only to the luggage room of a one-box car but also to the trunk room of a sedan type vehicle. In the floor portion of the luggage room, a spare tire storage recess is provided in the floor panel. In order to fix the spare tire stored in the spare tire storage recess, a bracket fixed by welding to the vehicle body side is provided. The spare tire is fixed by screwing a clamp for fixing the wheel portion of the spare tire in the mounting hole.

  Furthermore, the present invention is characterized by the shape of the spacer inserted between the upper surface of the clamp and the lower surface of the luggage floor board. That is, the annular protrusions are formed so as to project and hold the flanges of the clamps on the front and back sides of the spacer body so that both the normal posture and the inverted posture of the spacer can be used. A projection receiving surface that receives the pressing protrusion on the luggage floor board side is set on the front and back sides on the outer side of the annular convex portion, and a clamp contact surface that contacts the flange of the clamp on the inner side of the annular convex portion Is set on the front and back sides. In addition, the projecting dimension of each annular projection is different so that the front side and the back side can be visually confirmed, and the height dimension of the pressing projection is set larger than the projecting dimension of each annular projection. Has been. As the spacer material and molding method, synthetic resin such as PP (polypropylene) resin can be used, and it is preferable to adopt an injection molding method.

  Therefore, due to the difference in specifications of the spare tire, for example, the position of the spacer when storing a spare tire with a small size is such that the clamp contact surface on the side where the distance from the center line of the spacer to the clamp contact surface is longer is the flange of the clamp. Maintaining the normal posture of the spacer so that it hits. Conversely, when storing a spare tire with a large size, maintain the spacer inversion posture so that the clamp contact surface on the side where the distance from the center line of the spacer to the clamp contact surface is short contacts the flange of the clamp, If a spacer is inserted, the projection receiving surface that receives the pressing projection on the luggage floor board side can be controlled to a certain height position. As a result, the mounting height position of the luggage floor board can always be kept constant.

  Next, in a preferred embodiment of the present invention, the pressing protrusion provided on the luggage floor board is set on the lower surface side of the luggage box integrated with the luggage floor board, and the pressing protrusion is formed on the luggage box. It is characterized by being formed integrally with.

  And if you adopt the configuration of setting the press projection on the luggage box integrated with the luggage floor board, the press projection can be formed simultaneously with the molding of the luggage box made of synthetic resin injection molded body, so the luggage Compared with the case where the pressing protrusions are set directly on the floor board, when selecting the material of the luggage floor board, it is not necessary to consider the formability so much, so a wide range of materials can be selected.

  As described above, in the luggage floor structure of a vehicle according to the present invention, after the spare tire stored in the spare tire storage recess of the floor panel is fixed with the clamp, the spacer is interposed between the upper surface of the clamp and the luggage floor board. In addition, the load floorboard support structure that effectively receives the load from the luggage floorboard is adopted, and in the shape of the spacer, from the center line of the spacer divided in the thickness direction of the spacer to the clamp contact surface on the front and back sides, respectively. By making the distances different, the distance between the projection receiving surface and the clamp contact surface can be made different between the normal posture and the reverse posture of the spacer. Therefore, by reversing the spacer against the difference in the dimensions of spare tires with different specifications, the height position of the projection receiving surface of the spacer and the mounting height position of the luggage floor board can always be kept constant, Conventionally, a plurality of required spacers can be shared by a single spacer, so that the cost of parts and molds can be reduced.

  In addition, the height of the projection receiving surface that receives the pressure projection on the luggage floor board side is always constant by using the spacer properly in the normal posture and the inverted posture according to the difference in specifications of the spare tire. It has the effect of being able to support stably.

  Hereinafter, a specific example of a luggage floor structure for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings. Note that the gist of the present invention is as described in the scope of claims, and the contents of the embodiments described below are merely examples of the present invention.

  1 to 7 show an embodiment of the present invention. FIG. 1 is an overall view showing a luggage floor structure according to the present invention, and FIG. 2 shows a use form of a spacer in a normal posture in the luggage floor structure. FIGS. 3 to 6 are a plan view, a side view, a bottom view, and a cross-sectional view of a spacer used in the luggage floor structure, and FIG. 7 shows a usage pattern of the spacer floor structure in an inverted posture. It is explanatory drawing.

  In FIG. 1 and FIG. 2, a luggage box 11 that can accommodate equipment is integrated with a part of the lower surface of a luggage floor board 10 provided on the floor portion of the luggage room 2, and the luggage floor provided with the luggage box 11. The board 10 is detachably attached to the floor panel 20 by clip means or the like (not shown). Further, in order to store the spare tire 30 (here, a small spare tire 30A of the two specifications is used), the floor panel 20 is provided with a spare tire storage recess 21 so that the spare tire is stored. A bracket 22 for fixing a clamp 40 for fixing 30A in a screwed manner is fixed to the floor panel 20 by welding.

  A spacer 50 is inserted in the space between the lower surface of the luggage box 11 of the luggage floor board 10 and the clamp 40, and a structure for stably supporting the luggage floor board 10 by the spacer 50 is employed. . In particular, the two spacer tires 30A and 30B having different dimensions are characterized in that the spacer 50 can be shared by setting the same spacer 50 to a normal posture and a reverse posture. FIG. 2 shows a usage pattern of the spacer 50 when the spare tire 30A having a small size is stored. This state is a normal posture of the spacer 50. FIG. The spacer 50 is inserted between the pressing protrusion 12 formed on the luggage box 11 integrated on the lower surface of the luggage floor board 10 and the disc-shaped flange 41 of the clamp 40. The shape of the spacer 50 is as follows. 3 to 6, the spacer 50 is formed into a required shape by injection molding synthetic resin such as PP (polypropylene) resin, and is formed on the front and back surfaces of the substantially disc-shaped spacer body 51. Annular protrusions 52A and 52B (when the spacer 50 is in the normal posture, the annular protrusion on the upper surface side is 52A and the annular protrusion on the lower surface side is 52B) are provided. Here, by setting the projecting dimension of the annular convex portion 52A coming to the upper surface side in the normal posture to be shorter than the projecting dimension of the annular convex portion 52B on the lower surface side, the normal posture or the reverse posture of the spacer 50 can be easily set. It can be visually confirmed. The annular convex portions 52A and 52B can hold the disc-shaped flange 41 of the clamp 40 so that the spacer 50 can be maintained in a stable posture in both the normal posture and the inverted posture. Here, the dimensional relationship between the pressing protrusion 12 and each of the annular protrusions 52 </ b> A and 52 </ b> B is set such that the annular protrusion 52 </ b> A <the annular protrusion 52 </ b> B ≦ the pressing protrusion 12.

  And about the spacer 50, since the pressing protrusion 12 protrudingly formed on the back surface of the luggage box 11 presses the outside of the annular convex portions 52A, 52B of the spacer 50, the protrusion receiving surfaces 53A, 53B that receive the pressing protrusion 12 are provided. It is set outside the annular convex portions 52A and 52B. Further, the opposite surfaces, that is, the clamp contact surfaces 54A and 54B that contact the flange 41 of the clamp 40 are set inside the annular protrusions 52A and 52B.

  As shown in FIG. 6, the spacer 50 has a center line that bisects the spacer main body 51 in the thickness direction at an equal distance d1 from both projection receiving surfaces 53A and 53B located outside the annular convex portions 52A and 52B. With reference to (indicated by P in FIG. 6), distances d2 and d3 from the center line P to the clamp contact surfaces 54A and 54B are set to d2> d3. Further, the distance L2 from the projection receiving surface 53B to the clamp contact surface 54B in the inverted posture is set shorter than the distance L1 from the projection receiving surface 53A to the clamp contact surface 54A in the normal posture.

  Therefore, in the usage form in the normal posture of the spacer 50 shown in FIG. 2, the spare tire 30A having a small size is stored in the spare tire storage recess 21 of the floor panel 20, and the wheel portion 31A of the spare tire 30A is clamped by the clamp 40. The spare tire 30 </ b> A can be reliably fixed by pressing and holding and screwing the threaded rod 42 of the clamp 40 into the screw hole of the bracket 22 in the floor panel 20. Then, after placing the spacer 50 so that the flange 41 of the clamp 40 is fitted, if the luggage floor board 10 is attached from above the spacer 50, the pressing protrusion 12 provided on the luggage box 11 of the luggage floor board 10 becomes the spacer 50. The projection receiving surface 53A installed outside the annular projection 52A is pressed, and in this state, the distance L1 between the projection receiving surface 53A of the spacer 50 and the clamp contact surface 54A is obtained. The spacer 50 provides stable support for the luggage floor board 10.

  Further, when using a large spare tire 30B having different specifications in place of the spare tire 30A, the wheel portion 31B of the spare tire 30B is held and fixed by the clamp 40, and then the spacer 50 is reversed to As shown in FIG. 7, it is used in a reversed posture. That is, the spacer 50 is set on the flange 41 of the clamp 40 so that the annular protrusion 52B having a large projecting dimension becomes the upper surface. At this time, the pressing protrusion 12 of the luggage box 11 on the luggage floor board 10 contacts the protrusion receiving surface 53B set outside the annular protrusion 52B, and is positioned on the lower surface side of the spacer 50 with respect to the flange 41 of the clamp 40. 2 and the distance L2 between the projection receiving surface 53B and the clamp contact surface 54B is L2 <L1, so the height positions of the luggage floor board 10 and the luggage box 11 are almost the same as those in FIG. It can be controlled to the same height position.

  As described above, in the shape of the spacer 50, the annular protrusions 52A and 52B are formed on the front and back sides of the spacer main body 51, and the height positions of the clamp contact surfaces 54A and 54B inside the annular protrusions 52A and 52B are set. When the spacer 50 is reversed, the difference between the spare tires 30A and 30B is made to be compatible with the fluctuations of the spare tires 30A and 30B. Even if it is used, the luggage floor board 10 can always be maintained at a fixed height position. Therefore, the manufacturing cost of the spacer 50 can be reduced, leading to cost reduction and an effect that a support structure that is always stable against the load applied to the luggage floor board 10 can be obtained. Further, in the embodiment described above, the pressing protrusion 12 that presses the spacer 50 is provided in the luggage box 11, but it can also be set on the luggage floor board 10.

  The luggage floor structure of the vehicle described above can be applied not only to the luggage floor structure in the luggage room in the one-box car but also to the luggage floor structure in the trunk room. The material of the spacer is not limited to PP (polypropylene) resin, and other resin molded bodies or foamed resin molded bodies can be used. Furthermore, the annular convex portions 52A and 52B provided on the front and back surfaces of the spacer 50 may be formed at any time, for example, by intermittently forming the annular convex portions 52A and 52B along the annular shape.
