The cargo room deck board according to claim 1, wherein the deck board is used in a vehicle.

  In addition, in this section, the reference numerals and drawing numbers appended to the above terms are not intended to limit the technical scope of the present invention to the “Example” section and the contents of the drawings described later.

  The effects of the present invention are as follows.

According to the first aspect of the present invention, two boards juxtaposed in the luggage compartment in the rear part of the vehicle body and the opposing edges of the two boards are pivoted to each other, and one board is centered on the pivot. A hinge that makes the other board relatively rotatable, a coil spring that elastically urges the other board to rotate in one direction, and an opposing edge of the one board. In the luggage compartment deck board in a vehicle provided with a connection bracket for connecting the opposite edge to the vehicle body side,
A first space is formed between the opposing edges in a state where the boards are arranged in a horizontal direction by relative rotation of the boards, and the opposing edges face each other. A second space that communicates with the first space is formed between the connection bracket portion and a part of the coil portion of the spring is accommodated in the first space of the first and second spaces. On the other hand, the other part of the coil part is accommodated in the second space .

  For this reason, in the assembly work of the deck board, when the four members of the two boards, the spring, and the connecting bracket are sequentially assembled, the coil portion of the spring is accommodated in the first and second spaces as described above. The four members can be positioned relative to each other. Therefore, the positioning of the deck board can be facilitated by this positioning.

  The invention according to claim 2 is that the spring has two extending portions extending from the coil portion, and one of the extending portions is on the opposite edge side of the one board. The other extension is attached to the other board.

  For this reason, the urging force by the spring is transmitted more directly to the other board via the other extending portion of the spring. Therefore, the desired rotation in the one direction by the other board is more reliably achieved.

  According to a third aspect of the present invention, one extension portion of the spring is held by a combination of the opposing edge portion of the one board and the connection bracket so as to be movable in the longitudinal direction.

  Here, it is assumed that the other board is largely rotated in the opposite direction to the one direction against the biasing force of the spring with respect to the one board. Then, in this case, the spring is pulled so that the two extending portions are largely separated from each other, and the biasing force by the coil portion of the spring tends to increase.

  Therefore, first, when the operation of rotating the other board in the direction opposite to the rotation direction in one direction as described above with respect to the one board, the operation is performed due to an increase in the biasing force. May cause inhibition. Second, the coil portion of the spring, which is located between the two extension portions and is largely pulled, tends to come into pressure contact with the boards and hinges. This is not preferable because the deck board may cause abnormal noise or damage during the operation.

  However, according to the invention, the one extension part of the spring is held by the combination of the opposing edge part of the one board and the connection bracket so as to be movable in the longitudinal direction. Even if the two extending portions of the spring are about to be largely separated from each other by largely rotating the other board with respect to one board, in this case, the one extending portion of the spring moves in the longitudinal direction. Thus, the two extending portions are suppressed from being greatly separated from each other.

  Therefore, even if the other board is rotated with respect to the one board in the direction opposite to the rotation direction in one direction as described above, the two extending portions described above are pulled apart from each other. This is suppressed, and firstly, the above operation can be performed smoothly. Second, the coil portion of the spring is prevented from being pressed against both the boards and the hinges, and abnormal noise and damage to the deck board are prevented.

  Further, according to the invention, since the connection bracket is used to hold one extension portion of the spring against the opposite edge side of one board, the component part of the deck board is used for this use. And the configuration can be simplified.

  According to a fourth aspect of the present invention, there is provided a pair of projecting portions that project from the connecting bracket, surround the coil portion from the axial direction, and have the projecting side accommodated in the first space.

  For this reason, in the assembly work of the deck board, when the four members of the boards, the spring, and the connecting bracket are sequentially assembled, the first space is formed if the protrusions are accommodated in the first space. The opposing edges of the boards and the protrusions can be positioned relative to each other, that is, the boards and the connecting bracket can be positioned relative to each other. Therefore, this positioning makes it easier to assemble the deck board.

FIG. 4 is a partially enlarged view showing each board of FIG. 3 with virtual lines. FIG. 5 is a cross-sectional view taken along line VV in FIG. 4. It is a fragmentary perspective view of a deck board.

  In order to realize the purpose of facilitating the assembly work of the deck board, the form for carrying out the present invention is as follows with respect to the deck board for the cargo compartment in the vehicle of the present invention.

  That is, the deck board for the luggage compartment in the vehicle pivots around the two boards arranged in parallel in the luggage compartment in the rear part of the vehicle body and the opposing edges of the two boards, and the pivot part is the center. A hinge that rotates the other board relative to one board, a coil spring that elastically biases the other board to rotate in one direction, and an attachment to the opposite edge of the one board And a connection bracket for connecting the opposite edge portion to the vehicle body side.

A first space is formed between the opposing edges in a state where the boards are arranged in a horizontal direction by relative rotation of the boards, and the opposing edges face each other. A second space that communicates with the first space is formed between the connection bracket portion and a part of the coil portion of the spring is accommodated in the first space of the first and second spaces. On the other hand, the other part of the coil part is accommodated in the second space .

  In order to explain the present invention in more detail, an embodiment thereof will be described with reference to the accompanying drawings.

It is attached with a tool 33.

  The deck board 21 includes a pair of left and right connecting brackets 37 and 37 made of resin and attached to the lower surface of the opposite edge portion 25 a of the rear board 25 by a fastener 36. On the other hand, the seat cushion 15 of the rear seat 13 which is a member on the vehicle body 2 side has a seat cushion frame 15a, and a pair of left and right engagement arms 38, 38 project rearward and upward from the seat cushion frame 15a. It is installed. The protruding end portions of the engagement arms 38 and the connection brackets 37 are detachably engaged with each other. The opposing edge portion 25a of the rear board 25 is connected to the seat cushion frame 15a via the connecting bracket 37 and the engaging arm 38 that are engaged with each other.

  The connection bracket 37 is integrally formed with the rectangular substrate 40 in a plan view attached to the lower surface of the opposite edge portion 25a of the rear board 25 by the fastener 36 from the front edge portion of the substrate 40 toward the front lower side. It has an engaging protrusion 41 that protrudes and the protruding end portion engages with the protruding end portion of the engaging arm 38. The engaging projection 41 includes a pair of left and right projecting pieces 42 and 42 that project integrally from the front edge of the substrate 40 toward the front lower side, and the left and right projecting pieces 42 that extend in the width direction of the vehicle body 2. And an engaging shaft 43 that is integrally installed on the protruding end portion of the main body 42. An engaging recess 38a formed so as to open upward at the protruding end of the engaging arm 38 and the engaging shaft 43 are engaged with each other in an up-and-down direction.

  The front edge portion of the substrate 40 between the base portions of the left and right protruding pieces 42, 42 follows the protrusion of the engaging protrusion 41 projecting forward and downward as described above, and is more than the general portion of the substrate 40. It is bent downward so as to be positioned lower. Accordingly, a recess 45 that opens upward is formed between the upper surface of the front edge portion of the substrate 40 between the base portions of the left and right protruding pieces 42 and 42 and the base portions of the left and right protruding pieces 42 and 42. Is formed.

  In a state in which the boards 24 and 25 are arranged side by side in a substantially horizontal direction by the relative rotations C and D of the boards 24 and 25 (solid lines in FIGS. 1 to 3), the space between the opposing edges 24a and 25a. A first space 46 that opens downward is formed. Further, between the opposing edge portions 24a and 25a and the portion (front end edge portion) of the connecting bracket 37 facing the upper and lower direction, the first space 46 communicates with each other, A second space 47 including a space is formed.

  The coil portion 30 of the spring 28 is accommodated so as to straddle the first and second spaces 46 and 47. Further, a pair of left and right projecting portions 48, 48 surrounding the coil portion 30 in the axial direction (the width direction of the vehicle body 2) are integrally formed on the upper surfaces of the base portions of the left and right projecting pieces 42, 42. Further, the protruding side of each protruding portion 48 is accommodated in the first space 46, respectively.

  A groove 49 that opens upward and extends linearly in the front-rear direction of the vehicle body 2 is formed on the upper surface of the substrate 40 of the connection bracket 37. The upper end opening of the groove 49 is closed by the opposing edge portion 25a of the rear board 25. One extending portion 31 of the spring 28 is fitted into the groove 49 so as to penetrate the groove 49. Thereby, this one extension part 31 is hold | maintained at the combination body 25a, 37 of the opposing edge part 25a of the said rear board 25, and the said connection bracket 37 so that the movement E can be carried out toward the longitudinal direction. .

  Further, an annular stopper 50 is formed at the extending end of the one extending portion 31 by bending of the extending portion 31. When one extension part 31 of the spring 28 is excessively moved forward E with respect to the connection bracket 37, the stopper 50 comes into contact with the rear end opening edge of the groove 49 in the substrate 40, and Further forward movement E of the one extending portion 31 is prevented.

  Usually, the seat back 16 of the rear seat 13 protrudes upward from the rear end portion of the seat cushion 15 (a chain line in FIGS. 1 and 2 and a chain double-dashed line). It is possible. At this time, the front board 24 of the deck board 21 is in a vertically oriented posture, and its rotating end is pressed against the back surface of the seat back 16 of the rear seat 13 by the biasing force of the spring 28. For this reason, when the seat back 16 is tilted back and forth B (a dashed line and a two-dot chain line in FIG. 2), the front board 24 prevents a gap from being generated between the seat back 16 and the deck board 21. The

  On the other hand, when the rear seat 13 is not used, when the seat back 16 is largely tilted forward (a three-dot chain line in FIG. 2) so that the seat back 16 overlaps the seat cushion 15, the front board 24 Is rotated forward (solid line in FIGS. 1 to 3) so as to be pressed against the back surface (upper surface) of the seat back 16 so that the cargo compartment 19 is enlarged forward.

  When the front / rear position of the rear seat 13 is adjusted by the forward / backward movement A of the seat cushion 15, the deck board 21 is interlocked with the seat cushion 15 via the connection bracket 37. Accordingly, the above-described related configuration between the seat back 16 of the rear seat 13 and the front and rear boards 24 and 25 of the deck board 21 is maintained.

  According to the above configuration, the first and second edges 24a and 25a are arranged between the opposing edges 24a and 25a in a state in which the boards 24 and 25 are arranged in the substantially horizontal direction by the relative rotations C and D of the boards 24 and 25. A space 46 is formed, and a second space 47 that communicates with the first space 46 is formed between the opposing edge portions 24a and 25a and the portion of the connecting bracket 37 that faces the opposing edges 24a and 25a. The coil portion 30 of the spring 28 is accommodated in the first and second spaces 46 and 47.

  For this reason, in the assembly work of the deck board 21, when the four members 24, 25, 28, 37 of the boards 24, 25, the spring 28, and the connecting bracket 37 are sequentially assembled, the coil portion 30 of the spring 28 is If the first and second spaces 46 and 47 are accommodated, the above-described four members 24, 25, 28 and 37 can be positioned relative to each other. Thus, the positioning of the deck board 21 can be facilitated by this positioning.

  As described above, the spring has two extending portions extending from the coil portion, and one of the extending portions is on the opposite edge side of the one board. The other extension is attached to the other board.

  For this reason, the urging force of the spring 28 is more directly transmitted to the other board 24 via the other extending portion 32 of the spring 28. Therefore, the desired rotation C in the one direction by the other board 24 is more reliably achieved.

  Further, as described above, the combined bodies 25a, 37 of the opposing edge portion 25a of the rear board 25 and the connecting bracket 37 so that one extension portion 31 of the spring 28 is movable in the longitudinal direction thereof. Is held in.

  Here, it is assumed that the front board 24 is largely rotated D in the direction opposite to the rotation C in one direction against the urging force of the spring 28 with respect to the rear board 25. Then, in this case, the spring 28 is pulled so that the extending portions 31 and 32 are largely separated from each other, and the urging force by the coil portion 30 of the spring 28 tends to increase.

  For this reason, first, when the front board 24 is rotated D in the direction opposite to the rotation C direction in one direction as described above, the increase in the biasing force causes the above-described rear board 25 to perform the above operation. The operation may be hindered. Secondly, the coil portion 30 of the spring 28 that is located between the extending portions 31 and 32 and is largely pulled tends to be in pressure contact with the boards 24 and 25 and the hinge 26. This is not preferable because the deck board 21 may be abnormally sounded or damaged during the above operation.

  However, according to the above-described configuration, the combination body 25a of the opposing edge portion 25a of the rear board 25 and the connection bracket 37 so that one extension portion 31 of the spring 28 can move in the longitudinal direction thereof. 37, even if both the extended portions 31 and 32 of the spring 28 try to be largely separated from each other by rotating the front board 24 largely with respect to the rear board 25, in this case, It is possible to prevent the extending portions 31 from moving in the longitudinal direction and the extending portions 31 and 32 from being greatly separated from each other.

  Therefore, even if the front board 24 is rotated D in the direction opposite to the rotation C direction in one direction as described above with respect to the rear board 25, both the extending portions 31 and 32 described above are mutually connected. Pulling at a large distance is suppressed, and firstly, the above operation can be performed smoothly. Second, the coil portion 30 of the spring 28 is prevented from being pressed against the boards 24, 25 and the hinge 26, and abnormal noise and damage to the deck board 21 are prevented.

  Further, according to the above configuration, since the connection bracket 37 is used to hold one extension portion 31 of the spring 28 against the opposite edge portion 25a side of the rear board 25, the deck is used for this usage. The configuration of the board 21 can be simplified by reducing the number of components.

  Further, according to the above configuration, the pair of projecting portions 48, 48 are provided so as to project from the connecting bracket 37, surround the coil portion 30 from the axial direction, and accommodate the projecting side in the first space 46. Yes.

  For this reason, in the assembly work of the deck board 21, when the four members 24, 25, 28, 37 of the boards 24, 25, the spring 28, and the connecting bracket 37 are sequentially assembled, the protrusions are inserted into the first space 46. If the portion 48 is accommodated, the opposing edges 24a, 25a of the boards 24, 25 forming the first space 46 and the protrusions 48 can be positioned relative to each other. 24, 25 and the connecting bracket 37 can be positioned with respect to each other. Thus, the positioning of the deck board 21 can be facilitated by this positioning.

  Prior to the positioning, when the protrusions 48 are to be accommodated in the first space 46, the opposing surfaces of the opposing edge portions 24a and 25a, which are the inner surfaces of the first space 46, and The front and rear surfaces of the protrusions 48 are in sliding contact with each other, and the first space 46 and the protrusions 48 are guided to the predetermined positions to be positioned. Therefore, also in this respect, the assembly work of the deck board 21 can be facilitated.

  Further, as described above, when each of the protrusions 48 is accommodated in the first space 46, when the front board 24 is about to rotate C toward the one direction with respect to the rear board 25, The inner surface of the first space 46 and the outer surface of each protrusion 48 come into contact with each other, and excessive rotation C in the one direction of the front board 24 is prevented. Therefore, also in this respect, the assembly work of the deck board 21 can be facilitated.

  Although the above is based on the illustrated example, the boards 24 and 25 may be arranged in parallel in the width direction of the vehicle body 2. The hinge 26 may be provided separately from the boards 24 and 25. Further, the connecting bracket 37 may connect the opposite edge portion 25a of the rear board 25 to the floor panel side of the vehicle body 2.
