The hinge pins 32 are arranged coaxially with each other so that the protruding ends face each other.

  The deck side trim 31 is provided with a shelf part 34 (support part) that supports the width direction side edge part of the tray main body part 21 in a horizontal posture from below. The shelf 34 is provided so as to protrude from the deck side trim 31 to the cargo compartment side, and extends in the vehicle front-rear direction. The shelf 34 is formed in a range from the lower side of the hinge pin 32 to the rear end side of the package tray 20 in the vehicle longitudinal direction.

  The pair of hinge collars 40 are made of a synthetic resin material and are respectively attached to both sides in the width direction at the front end of the tray main body 21. That is, each hinge collar 40 is provided at a location corresponding to each hinge pin 32. Each hinge collar 40 is pivotally supported by each hinge pin 32, so that the package tray 20 can be rotated between a horizontal posture and a forward tilt posture. In FIG. 1, the hinge pin 32 on the left side with respect to the vehicle traveling direction is not shown. 5 to 9, the left hinge pin 32 with respect to the vehicle traveling direction and the corresponding hinge collar 40 are shown.

  As shown in FIGS. 3 and 4, the hinge collar 40 includes a base portion 40A having a substantially plate shape, a backing portion 40B, and a connecting portion 61 that connects the base portion 40A and the backing portion 40B.

The backing portion 40B has a substantially plate shape, and as shown in FIG. 4, integrally with the back surface of the base portion 40A (the vehicle interior side surface, the left surface in FIG. 4) via the connecting portion 61. Is formed. The connecting portion 61 is set to a thickness that can be bent, and the backing portion 40B is rotatable with respect to the base portion 40A around the connecting portion 61 (hinge portion).

  As shown in FIG. 4, a lock protrusion 62 having a substantially cylindrical shape protrudes from the back surface of the base portion 40A. A locking claw 62A (broken line in FIG. 4) protrudes from the side surface of the lock projection 62. On the other hand, the backing portion 40B is formed with a lock hole 60A through which the lock projection 62 can be fitted. Further, an insertion hole 22 </ b> A is formed through the side portion 22 of the tray main body portion 21.

  In the present embodiment, when the base portion 40A and the backing portion 40B are overlapped with the connecting portion 61 as the center of rotation in a state where the lock hole 60A and the insertion hole 22A are arranged coaxially, the lock protrusion 62 is formed. It is configured to be fitted (inserted) into both the insertion hole 22A and the lock hole 60A, and the locking claw 62A is hooked on the hole edge of the lock hole 60A from the vehicle interior side and locked (state of FIG. 4). .

  Thereby, the side part 22 of the tray main body part 21 is sandwiched between the base part 40A and the backing part 40B, and the hinge collar 40 is attached to the tray main body part 21. In addition, the attachment structure of the hinge collar 40 with respect to the tray main-body part 21 is not limited to this structure, It can change suitably, For example, you may attach the hinge collar 40 to the tray main-body part 21 by screwing etc.

  As shown in FIGS. 3 and 5, the base portion 40 </ b> A of the hinge collar 40 is provided with a recessed portion 41 having a shape recessed inward in the width direction of the package tray 20 (the vehicle width direction, the paper surface penetration direction in FIG. 5). It has been. The recessed portion 41 is formed so as to open to the opposing deck side trim 31 side, and can accommodate the hinge pin 32 protruding from the deck side trim 31. The concave portion 41 extends in a substantially V-shape opening downward in a side view shown in FIG. A central portion in the vehicle front-rear direction in the substantially V-shaped concave portion 41 is an accommodation groove 42 (which constitutes a bearing portion) in which the hinge pin 32 is accommodated.

  As shown in FIG. 6, the base portion 40 </ b> A (one of the support portion and the package tray) includes a protruding portion 47 that protrudes downward (the other of the support portion and the package tray). The protruding portion 47 has a substantially trapezoidal shape in a side view, and the upper surface 47 </ b> A constitutes the accommodating groove 42. In other words, the protruding portion 47 is provided below the housing groove 42 so as to be close thereto.

  Further, as shown in FIG. 5, the protruding end (lower end) of the protruding portion 47 is positioned below the lower surface 21 </ b> A of the tray main body 21, and most of the protruding portion 47 is the lower surface of the tray main body 21. It is arranged below 21A. In other words, the protrusion 47 has a shape protruding from the lower surface 21 </ b> A of the tray main body 21.

  Further, on the lower surface 41B of the concave portion 41 (a surface facing downward among the surfaces constituting the concave portion), a front-side bent protrusion portion 50 and a rear-side protrusion portion 51 are respectively provided. The hinge pin 32 is held in the accommodation groove 42 by a protrusion 47, a front-side bending protrusion 50, and a rear-side protrusion 51 (see FIG. 6).

  That is, the protruding portion 47, the front-side bent protruding portion 50, and the rear-side protruding portion 51 constitute a bearing portion to which the hinge pin 32 is attached. In the following description, the state where the hinge pin 32 is housed in the housing groove 42 and is held by the projecting portion 47, the front-side deflecting projecting portion 50, and the rear-side projecting portion 51 (the state shown in FIG. 9) is referred to as a regular attachment state. Shall. Further, in FIG. 8, the hinge pin 32 in a normally attached state is illustrated by a two-dot chain line.

  As shown in FIG. 6, the front-side bending protrusion 50 is provided obliquely forward (upper left in FIG. 6) with respect to the upper surface 47 </ b> A of the protrusion 47. The front-side deflection protrusion 50 is formed in a double-sided manner with respect to the lower surface 41B of the recess 41. Thereby, the front side bending protrusion part 50 can be elastically bent and deformed in a direction in which the center part (free end) is separated from the protrusion part 47. Further, the central portion of the front-side bending protrusion 50 protrudes toward the protrusion 47 and is disposed on the moving path of the hinge pin 32 in the recess 41.

  As shown in FIG. 6, the rear protrusion 51 is provided obliquely rearward (upper right side in FIG. 6) with respect to the upper surface 47 </ b> A of the protrusion 47. The rear protrusion 51 protrudes toward the protrusion 47 and is disposed on the moving path of the hinge pin 32 in the recess 41.

  Further, as shown in FIG. 6, a contact protrusion 47B having an elongated shape is provided on the upper surface 47A of the protrusion 47. Further, an opposing protrusion 48B is provided at a position facing the contact protrusion 47B in the up-down direction (between the front-side bending protrusion 50 and the rear protrusion 51). The hinge pin 32 in the normal attachment state is in contact with the contact protrusion 47B.

  Further, a positioning bead 49 (positioning protrusion) that protrudes toward the opposing deck side trim 31 is provided above the recess 41 in the base portion 40A. The positioning bead 49 abuts on the deck side trim 31 to perform positioning of the package tray 20 in the vehicle width direction, and also has a function of suppressing the play of the package tray 20 with respect to the hinge pin 32.

  The positioning bead 49 positions the package tray 20 in the vehicle width direction, thereby preventing the protruding end (tip) of the hinge pin 32 from coming into contact with the inner surface 41A of the recess 41. Thus, the package tray 20 can be smoothly rotated with respect to the hinge pin 32.

  In order to more effectively suppress the backlash of the package tray 20 with respect to the hinge pin 32, it is preferable to reduce the distance between the positioning bead 49 and the hinge pin 32 (and thus the accommodation groove 42). For this reason, the positioning bead 49 has a shape extending along the shape of the recess 41 (substantially V-shaped opening downward) in a side view, and extends so as to be close to the hinge pin 32.

  A portion of the recess 41 behind the housing groove 42 is an extended groove 45 extending downward and inclined toward the rear of the vehicle. The extending groove 45 is formed between the lower surface 41 </ b> B of the recess 41 and the rear surface 47 </ b> D of the protrusion 47. The extended groove 45 is opened rearward and downward (in an oblique direction) of the vehicle, and has a groove width larger than the outer diameter of the hinge pin 32. Moreover, the groove width of the extended groove 45 is configured to increase toward the opening side.

  The extending groove 45 is configured to allow the hinge pin 32 to escape in a direction in which the load applied to the hinge pin 32 is reduced when the hinge pin 32 in the normal attachment state receives a predetermined amount of load that does not exceed the elastic limit. That is, the extended groove 45 is an escape groove for allowing the hinge pin 32 to escape. Specifically, when the package tray 20 is pressed forward in the normal mounting state, the hinge pin 32 deflects the protruding portion 47 downward (in the direction away from the lower surface 41B of the recess 41), thereby extending the extending groove. 45 is movable.

  Further, since the extending groove 45 extends so as to be inclined downward toward the rear of the vehicle, when the package tray 20 is in a forward inclined posture, the extending groove 45 is opened toward the rear of the vehicle. For this reason, when the package tray 20 in the forward leaning posture is pressed forward of the vehicle by the back door, the hinge pin 32 can be more reliably released.

  In the present embodiment, the hinge pin 32 is guided to the receiving groove 42 by displacing the package tray 20 forward of the vehicle in a state where the hinge pin 32 is disposed in front of the vehicle of the package tray 20 (state of FIG. 5). The package tray 20 is assembled to the hinge pin 32. Next, this configuration will be described in detail.

  A portion of the recess 41 in front of the accommodation groove 42 is a guide groove 43 (guide path) for guiding the hinge pin 32 to the accommodation groove 42. The guide groove 43 has a groove width larger than the diameter of the hinge pin 32, and is opened forward and downward of the vehicle as shown in FIG. The guide groove 43 is formed between the lower surface 41B of the recess 41 and the front surface 47F of the protrusion 47.

  The guide groove 43 extends so as to rise and incline toward the rear of the vehicle, and communicates with the accommodation groove 42 at the rear end. The extending direction of the guide groove 43 is, for example, an angle of 45 degrees with respect to the horizontal direction, but is not limited to this inclination angle and can be changed as appropriate.

  A front end of the upper surface 34A (surface supporting the tray main body portion 21) of the shelf portion 34 is a notched portion 35 (recessed portion, inserted portion) that is notched downward. The cutout portion 35 can be inserted (fit) into the projecting portion 47 of the package tray 20. By configuring such a notch 35, the upper surface 34A of the shelf 34 is lowered in a stepped shape at the front end thereof.

  Further, the inner surface 35A of the notch 35 has a curved shape along the rotation locus of the protruding end surface 47E (lower surface) of the protruding portion 47 when the package tray 20 rotates around the hinge pin 32. Is configured to be rotatable without interfering with the shelf 34. The projecting end surface 47E of the projecting portion 47 is a curved surface that slightly rises and tilts forward, and has a shape that can more reliably avoid a situation where the projecting portion 47 interferes with the shelf portion 34 when the package tray 20 rotates. .

  Further, the front end surface 34B of the shelf portion 34 is an inclined surface that is inclined downward toward the front of the vehicle. For example, the package tray 20 removed from the hinge pin 32 can be leaned against the front end surface 34B. As a result, the package tray 20 can be disposed in a standing posture between the rear seat 12 and the shelf 34.

  Next, a procedure for assembling the package tray 20 in the present embodiment will be described. First, the operator places (abuts) the projecting portion 47 (projecting end surface 47E) of the package tray 20 on the upper surface 34A of the shelf portion 34, and the hinge pin 32 is arranged in front of the package tray 20 (see FIG. 5 state).

  In the state where the protruding portion 47 is placed on the upper surface 34A of the shelf portion 34, as shown in FIG. 5, the front end portion 20A on the lower surface of the package tray 20 (a portion in front of the protruding portion 47, the tray main body portion 21). The lower end of the guide collar 43 and the lower face of the hinge collar 40 are disposed above the hinge pin 32, and the opening end of the guide groove 43 and the hinge pin 32 are disposed at substantially the same height.

  From this state, the package tray 20 is moved along the shelf 34 forward of the vehicle. Then, the projecting portion 47 of the package tray 20 is slid forward of the vehicle with respect to the upper surface 34 </ b> A of the shelf portion 34. Eventually, the protrusion 47 reaches the notch 35 formed at the front end of the shelf 34 (see FIG. 6). In this state, the hinge pin 32 is arranged close to the front of the opening end of the guide groove 43.

  When the package tray 20 is moved further forward after the protrusion 47 reaches the notch 35, the protrusion 47 is inserted into the notch 35 (see FIG. 7). The projecting portion 47 is inserted into the cutout portion 35 which is a lower portion on the upper surface 34A of the shelf portion 34, whereby the package tray 20 is displaced downward. As a result, the front end 20 </ b> A (the lower surface of the hinge collar 32) on the lower surface of the package tray 20 abuts on the hinge pin 32.

  The package tray 20 is moved forward, and the projecting portion 47 is inserted into the notch 35, whereby the package tray 20 moves forward and is displaced downward (displaced obliquely). That is, the hinge pin 32 moves relative to the package tray 20 rearward and upward. As a result, the hinge pin 32 disposed in front of the guide groove 43 enters the guide groove 43 from the front and below (see FIG. 8).

  Thus, in the present embodiment, in the process of moving the package tray 20 forward, the package tray 20 can be displaced in an oblique direction while being in a horizontal posture by inserting the protruding portion 47 into the cutout portion 35. . As a result, the hinge pin 32 can be relatively moved along the guide groove 43 extending in the oblique direction. That is, the cutout portion 35 can be said to be a displacement allowing portion that allows a downward displacement of the package tray 20.

  When the hinge pin 32 enters the guide groove 43 and further presses the package tray 20 forward, the hinge pin 32 slides on the lower surface 43B of the guide groove 43 (a part of the lower surface 41B of the recess 41), and the receiving groove Guided to 42. In the process of guiding the hinge pin 32 to the guide groove 43, the hinge pin 32 does not necessarily have to be in contact with the lower surface 43 </ b> B of the guide groove 43. For example, the hinge pin 32 may abut on the front surface 47 </ b> F of the protruding portion 47 constituting the guide groove 43.

  When the hinge pin 32 toward the accommodation groove 42 enters the accommodation groove 42, the hinge pin 32 gets over the front deflection protrusion 50 while bending the front deflection protrusion 50. As shown in FIG. 9, the hinge pin 32 that has passed over the front deflection protrusion 50 is accommodated in the accommodation groove 42, as well as the protrusion 47 (more precisely, the contact protrusion 47 </ b> B on the upper surface 47 </ b> A), and the front deflection protrusion. 50, held by the rear protrusion 51. Thereby, the package tray 20 is assembled | attached with respect to the hinge pin 32 so that rotation is possible.

  Next, the effect of this embodiment will be described. According to the assembly structure of the package tray 20 in the present embodiment, the package tray 20 is moved forward along the shelf 34 from the state in which the hinge pin 32 is disposed on the front side of the package tray 20 in the vehicle. The hinge pin 32 can be guided to the receiving groove 42. Thereby, the assembly | attachment property of the package tray 20 can be made higher.

  Further, in the above configuration, the bearing portion has the accommodation groove 42 that can accommodate the hinge pin 32, the guide path is a guide groove 43 that communicates with the accommodation groove 42, and the protruding portion 47 is accommodated in the package tray 20. It is provided below the groove 42.

  By providing the projecting portion 47 below the housing groove 42, for example, the projecting portion 47 and the housing groove 42 are compared with a configuration in which the projecting portion 47 is arranged so as to shift in the vehicle front-rear direction with respect to the housing groove 42. The distance can be made smaller. Thereby, in the state where the protruding portion 47 is in contact with the shelf portion 34, the swinging of the hinge collar 40 (and thus the accommodation groove 42) around the contact portion between the protruding portion 47 and the shelf portion 34 is suppressed. Can do. For this reason, when the package tray 20 is assembled, the swinging of the hinge collar 40 can be suppressed. As a result, the hinge pin 32 can be more reliably guided to the receiving groove 42.

  In the present embodiment, in the process of assembling the package tray 20, the projecting portion 47 is inserted into the cutout portion 35, so that the package tray 20 is displaced downward. That is, when the assembly is completed, the height position of the package tray 20 is lower than that at the start of the assembly (state in FIG. 5). For this reason, it is possible to easily confirm that the package tray 20 is correctly attached to the hinge pin 32 by confirming the change in the height position of the package tray 20.

  If the assembling operation is interrupted when the protruding portion 47 is not inserted into the cutout portion 35 (the state shown in FIGS. 5 and 6), the package tray 20 has the protruding portion 47 arranged on the shelf portion 34. As a result of being placed on the upper surface 34A, the rearward tilting posture (not the horizontal posture) is obtained. Thereby, the assembling operator can easily confirm that the package tray 20 is not properly attached to the hinge pin 32.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. The same parts as those in the above embodiment are denoted by the same reference numerals, and redundant description is omitted. In the assembly structure of the package tray 120 of this embodiment, the structure of a protrusion part and a to-be-inserted part differs from the said embodiment.

  In the above embodiment, the protrusion is provided on the hinge collar 40. On the other hand, in the present embodiment, as shown in FIGS. 10 and 11, the protruding portion 147 is provided on the tray body 21. The protruding portion 147 is formed so as to protrude from the lower surface 21 </ b> A of the side portion 22 in the tray main body portion 21. On the other hand, on the upper surface 34A of the shelf portion 34, a shelf-side concave portion 135 (inserted portion) into which the protruding portion 147 can be inserted (fitted) is formed.

  With such a configuration, in the process of assembling the package tray 120, the package tray 120 is moved forward from the state in which the protruding end surface 147E of the protruding portion 147 contacts the upper surface 34A of the shelf portion 34 (the state in FIG. 10). By moving, the protrusion 147 can be inserted into the shelf-side recess 135. As a result, the package tray 120 can be displaced downward, and the hinge pin 32 can be caused to enter the guide groove 143 obliquely from below. As a result, the hinge pin 32 can be guided to the receiving groove 42 (state of FIG. 11). .

  As described in the above embodiment and the present embodiment, when the protrusion is provided on the package tray, either the hinge collar 40 or the tray main body 21 can be selected to provide the protrusion. By the way, in the process of assembling the package tray, the projecting portion comes into contact with the shelf portion 34 and becomes a portion that supports the weight of the package tray.

  From such a situation, it is preferable that the protrusion has a higher rigidity. For this reason, if the rigidity of the hinge collar 40 is higher than the rigidity of the tray main body 21, it is more preferable to form the protrusion 47 on the hinge collar 40. For example, when the tray body 21 is configured by impregnating fibers and a thermoplastic resin and the hinge collar 40 is configured by a single synthetic resin material, the hinge collar 40 is often more rigid. In this case, it is preferable to form the protrusion 47 on the hinge collar 40.

  Further, if the tray body 21 is formed by press molding and the hinge collar 40 is formed by injection molding, it is preferable to form a protrusion on the hinge collar 40. This is because, in order to integrally provide the protrusions on the tray main body portion 21 formed by press molding, it is necessary to remove the periphery of the protrusions from the board before pressing, so the yield decreases. On the other hand, when the protrusion is provided on the hinge collar 40 formed by injection molding, the yield does not decrease.

<Embodiment 3>
Next, Embodiment 3 of the present invention will be described with reference to FIGS. The same parts as those in the above embodiment are denoted by the same reference numerals, and redundant description is omitted. In the assembly structure of the package tray 220 of this embodiment, the structure of a protrusion part and a to-be-inserted part differs from the said embodiment.

  In the present embodiment, as shown in FIGS. 12 and 13, the protruding portion 235 is provided on the shelf portion 34. Correspondingly, a main body-side concave portion 247 (inserted portion) is provided in a shape in which the lower surface 21A of the side portion 22 in the tray main body portion 21 is recessed. The protruding portion 235 protrudes upward (on the package tray 220 side) from the upper surface 34A of the shelf portion 34. On the other hand, the main body side recess 247 is opened downward and has a shape in which the protrusion 235 can be inserted (fitted).

  Moreover, the vehicle rear side in the protrusion part 235 is set as the inclined surface 235B which inclines and descends toward the back. Accordingly, when the package tray 220 is moved forward from the rear of the protruding portion 235, the front end portion of the package tray 220 can ride on the protruding end surface 235A (upper surface) of the protruding portion 235.

  In the present embodiment, in the process of assembling the package tray 220, the package tray 220 is removed from the state where the lower surface 240D of the hinge collar 40 is supported (abutted) on the protruding end surface 235A of the protruding portion 235 (the state shown in FIG. 12). By moving forward, the protrusion 235 can be inserted into the main body side recess 247. As a result, the package tray 220 can be displaced downward, and the hinge pin 32 can be caused to enter the guide groove 143 obliquely from below. As a result, the hinge pin 32 can be guided to the receiving groove 42 (state of FIG. 13). .

  According to this embodiment, it is not necessary to provide a protrusion on the package tray 220 side. That is, since no projecting portion is provided on the lower surface of the package tray 220, the package tray 220 removed from the hinge pins 32 can be easily placed on the floor surface of the luggage compartment 30, for example.
