JP 2004-42864 A

  By the way, the conventional luggage mat is fixed to the inner bottom portion of the luggage box using a separate fixing member made of a hook-and-loop fastener or the like in order to prevent displacement with respect to the inner bottom portion of the luggage box. However, this increases the number of parts and the number of mounting steps, resulting in an increase in cost. Therefore, an object is to enable cost reduction by omitting fixing members other than the luggage box and the luggage mat.

In order to solve the above-mentioned problem, the present invention relates to a motorcycle luggage box structure according to the present application, wherein a motorcycle is provided with a luggage mat at the bottom of the luggage box.
The luggage mat is integrally provided with a mat side engaging portion, and correspondingly engaged with a box side engaging portion integrally formed at the bottom of the luggage box.

  A second aspect of the present invention is characterized in that, in the first aspect, the mat side engaging portion has a convex shape protruding toward the bottom of the luggage box, and the box side engaging portion has a concave shape.

  According to a third aspect of the present invention, in the motorcycle having the luggage mat provided at the bottom of the luggage box, a recess for accommodating the entire luggage mat is provided at the bottom of the luggage box. It is characterized by positioning the periphery.

A fourth aspect of the present invention according to the third aspect is characterized in that the stepped portion is formed of a rib integrally formed on the bottom portion so as to surround the periphery of the luggage mat.

  According to the first aspect of the present invention, a fixing member provided separately from the luggage box and the luggage mat, such as a conventional hook-and-loop fastener, is unnecessary, and the engagement structure between the luggage box and the luggage mat itself can be prevented from being displaced. Reduces man-hours and enables cost reduction.

  According to claim 2, the mat side engaging portion has a convex shape protruding toward the bottom portion of the luggage box, and the box side engaging portion has a concave shape, so that the mat side engaging portion is separated from the surface of the luggage mat. Do not protrude upward. For this reason. Even if the article is stored in the luggage box, the mat side engaging portion is hardly worn or deformed by the article, and the durability is improved because it is difficult to change over time.

  According to the third aspect, since the periphery of the luggage mat is positioned by the stepped portion surrounding the concave portion simply by laying the luggage mat in the concave portion at the bottom of the luggage box, a special fixing member separate from the luggage box and the luggage mat is provided. It is possible to easily prevent the displacement of the luggage mat without using it, thereby reducing the cost.

According to the fourth aspect, the step portion can be easily formed by forming the rib integrally with the bottom portion.

  FIG. 9 is a plan view of the luggage mat 50. The luggage mat 50 substantially coincides with the shape of the bottom portion 38, and a mat-side engaging portion 53 that protrudes downward and fits into the box-side engaging portion 43 is provided on the left and right sides of the front portion, and protrudes in the center. A bulging portion 58 is provided so as to overlap the portion 38a. A pair of mat side engaging portions 53 are also provided on the rear left and right of the luggage mat 50. A curved portion 57 that escapes the bulging portion 47 is formed at the left middle portion of the luggage mat 50.

  FIG. 10 shows a side view of the luggage mat 50. The luggage mat 50 is a member having a flat plate shape as a whole obtained by press-molding a nonwoven fabric or the like, and is formed so that the front center side is partially raised upward by the bulging portion 58. The front ends of the front and rear mat-side engaging portions 53 protrude downward from the bottom surface of the luggage mat 50. The mat side engaging portion 53 and the bulging portion 58 are integrally formed by press molding or the like when the luggage mat 50 is molded.

  11 is a cross section taken along line 11-11 of FIG. 9, and the mat side engaging portion 53 is formed to protrude downward from the bottom surface of the luggage mat 50. FIG. The upper surface side forms a concave portion 53a opened upward.

  FIG. 12 is a cross-sectional view showing a state in which the luggage mat 50 is stacked on the bottom 38 inside the luggage box. A in FIG. 12 is an engagement portion between the box side engagement portion 43 and the mat side engagement portion 53. And another part. As described above, the portion of the luggage mat 50 that does not engage with the bottom 38 is prevented from slipping by the periphery of the luggage mat 50 entering the inside of the rib 42 and sliding on the bottom 38 by the rib 42.

  At this time, the substantially vertical inner end face 42 a of the rib 42 forms a stepped portion that contacts the periphery of the luggage mat 50, and the upper surface of the rib 42 is substantially flush with the surface of the luggage mat 50. In this state, there is no step at the bottom of the luggage box.

  As described above, when the rib 42 is provided, the stepped portion for accommodating the luggage mat 50 and preventing the shift and the concave portion surrounded by the stepped portion can be easily formed. However, such a stepped portion is not necessarily formed by the rib 42, and the thickness of the bottom portion 38 may be thinned so as to match the shape of the luggage mat 50 to form the recessed portion and the stepped portion.

  B in the drawing is a cross section of the mat side engaging portion 53 in an overlapping state, and the mat side engaging portion 53 is loosely fitted into the box side engaging portion 43.

  Next, the operation of this embodiment will be described. When the luggage mat 50 is put into the luggage box 7 and stacked on the bottom portion 38, the periphery of the luggage mat 50 is fitted inside the rib 42 as shown in FIG. Further, as shown in B of FIG. 12, the mat side engaging portion 53 is loosely fitted to the box side engaging portion 43.

  For this reason, the luggage mat 50 is positioned around the ribs 42 and the mat side engaging portions 53 are loosely fitted into the box side engaging portions 43 on the left and right sides of the front and rear portions. Deviations in various directions are prevented. Further, a special fixing member provided separately from the bottom portion 38 of the luggage box and the luggage mat 50, such as a conventional hook-and-loop fastener, is unnecessary, and the engagement structure between the bottom portion 38 of the luggage box and the luggage mat 50 itself can prevent displacement. The cost can be reduced by reducing the number of parts and installation man-hours.

  At this time, in addition to positioning by the ribs 42, positioning by engagement of the mat side engaging portion 53 and the box side engaging portion 43 is used together. Even if it is loosely fitted, there is an effect of preventing slippage, and the fitting work becomes easy and quick.

  In addition, the mat side engaging portion 53 has a convex shape that protrudes toward the bottom portion 38 of the luggage box, and the box side engaging portion 43 has a concave shape, so that the mat side engaging portion 53 is separated from the surface of the luggage mat 50. Do not protrude upward. For this reason. Even if the article is stored in the luggage box 7, the mat-side engaging portion 53 is not easily worn or deformed by the article, and the durability is improved because it is difficult to change over time.

In addition, since the concave portion for accommodating the luggage mat 50 and the stepped portion surrounding the periphery thereof are formed by the ribs 42, the stepped portion is formed by simply laying the luggage mat 50 in the concave portion of the luggage box bottom 38. The periphery of the luggage mat 50 is positioned by the inner end face 42a of the rib 42 surrounding the periphery, and the displacement can be easily prevented simply by laying the luggage mat 50 in the luggage box, and the cost can be reduced. In addition, the concave portion for accommodating the luggage mat 50 and the stepped portion surrounding the concave portion can be easily formed by the rib 42.
