Description

[Technical Field]

[0001] The present invention relates to a deck board mounting structure applied to vehicles such as automobiles. [Background technology]

[0002] Specific examples of deck board mounting structures are described in Patent Documents 1 and 2. In the deck board mounting structures described in these documents, a recess for storing items is provided in the floor of the luggage compartment at the rear of the vehicle, and the upper side of the recess can be covered by a generally flat deck board laid on the floor. With this configuration, desired items can be stored in the recess, and the upper surface of the deck board can function as part of the approximately flat floor, allowing other items to be placed on top of it, which is convenient.

[0003] Furthermore, Patent Document 1 employs a configuration in which, when the back door that opens and closes the rear opening of the vehicle is closed, the rear of the deck board is sandwiched between the back door and a lower back portion at the lower edge of the rear opening. This configuration rationally secures the position of the deck board and prevents it from rattling. Meanwhile, in Patent Document 2, an additional recess is formed around the upper opening periphery of a recess for storing items in the floor of the luggage compartment, and the deck board is fitted into this additional recess for support. Even with this configuration, it is possible to position and fix the deck board and prevent it from wobbling.

[0004] However, the above-mentioned prior art still has room for improvement, as will be described below.

[0005] That is, in terms of vehicle specifications, there are cases where it is required to install the deck board at as low a height as possible and increase the height from the deck board to the ceiling surface in order to ensure sufficient luggage capacity. In contrast, with the configuration of Patent Document 1, it is difficult to install the deck board at a position lower than the lower back portion at the lower edge of the rear opening. Therefore, it is difficult to adopt the configuration of Patent Document 1 as a means to meet the above-mentioned demands.

[0006] On the other hand, in the configuration of Patent Document 2, unlike Patent Document 1, it is possible to install the deck board at a height lower than the lower bag portion. However, according to Patent Document 2, when a vehicle user puts or takes items into or out of the recess for storing items, it is not particularly easy to lift and move the deck board to widen the upper part of the recess, making it difficult to use. Furthermore, if a user lifts the rear part of the deck board upward while inside the vehicle, there is a risk that the user's hand or other body part may be pinched tightly between the deck board and the back door. It is desirable to appropriately resolve this issue. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent Publication No. 2021-54255 [Patent Document 2] Japanese Patent Application Laid-Open No. 2015-66994 Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention was conceived in light of the circumstances described above, and its object is to provide a deck board mounting structure that facilitates the operation of putting items into and taking items out of a predetermined item storage recess, and that can also appropriately prevent a user's hands from being pinched tightly between the deck board and the back door. [Means for solving the problem]

[0009] In order to solve the above problems, the present invention provides the following technical solutions.

[0010] The deck board mounting structure provided by the present invention comprises: an item storage recess provided in a floor portion of the luggage compartment at the rear of the vehicle; a deck board laid on the floor portion so as to cover the upper side of the recess; and a rear opening for a tailgate provided on the rear side of the floor portion of the vehicle. The deck board mounting structure is characterized in that it is also equipped with: deck board position restriction means that, when the deck board is laid down, restricts the position of the deck board to prevent movement in at least the fore-and-aft direction of the vehicle, and is configured so that when the rear portion of the deck board is lifted, the position restriction is released; and deck board slide support parts that support the front portion of the deck board and allow it to slide towards the front of the vehicle when the rear portion of the deck board is lifted and the position restriction is released.

[0011] With this configuration, when the deck board is laid on the floor of the luggage compartment so as to cover the upper side of the recessed portion for storing items, the deck board position restriction device prevents the deck board from moving at least in the fore-and-aft direction of the vehicle, so the deck board can be laid in a stable state with little wobble. In addition to this, the following additional effects can be obtained. First, when the deck board is laid down and the user lifts the rear portion of the deck board from outside the rear of the vehicle, the positional restriction for the deck board is released, and at the same time, the front portion of the deck board, supported by the slide support portion for the deck board, automatically or naturally slides toward the front of the vehicle. Therefore, the entire deck board can be easily moved toward the front of the vehicle as the rear portion of the deck board is lifted, making it easy to widely open the upper part of the recessed portion for storing items. As a result, it is easy to put items in and take them out of the recessed portion for storing items, making it easy to use. Second, if a user is in the vehicle and lifts the rear of the deck board upward, and the user's hand or other object becomes pinched between the deck board and the tailgate, the slide support section can move the deck board toward the front of the vehicle, as described above. This movement appropriately prevents the user's hand or other object from becoming pinched between the deck board and the tailgate, thereby increasing user safety.

[0012] Other features and advantages of the present invention will become more apparent from the following description of the preferred embodiments of the invention, which proceeds with reference to the accompanying drawings. [Brief explanation of the drawings]

[0014] Preferred embodiments of the present invention will now be described in detail with reference to the drawings.

[0015] The deck board mounting structure A shown in FIGS. 1 to 5 is a structure for laying front and rear deck boards 3, 4 on floor portion 13 of luggage compartment 10 at the rear of vehicle 1 such as an automobile. Here, rear deck board 4 corresponds to a specific example of a deck board of the present invention (claim 1), but front deck board 3 does not.

[0016] A plurality of recesses 14a, 14b for storing items, each of which has an opening at the top, are provided in floor portion 13. Floor portion 13 is provided with recessed portion 13a, and a resin storage case 14 is disposed in recessed portion 13a. The recesses 14a, 14b for storing items are recesses formed in storage case 14. The front and rear deck boards 3, 4 are laid on the floor portion 13 so as to close the upper sides of the recesses 14a, 14b for storing items, as will be described in detail later.

[0017] A rear seat 2 is installed on the vehicle front side of the floor portion 13. Meanwhile, a rear opening 12 for a tailgate that is opened and closed by a tailgate 11 shown by an imaginary line in FIG. 4 is provided at the rear of the vehicle 1, and luggage can be loaded and unloaded into the luggage compartment 10 through this rear opening 12. A lower back portion 5 equipped with a striker 18 for locking the tailgate is present at the lower peripheral edge of the rear opening 12 for the tailgate. As shown in FIG. 4, this lower back portion 5 is configured by combining a lower back panel 51 made of metal or the like and a lower back trim 50 made of resin. In this embodiment, as will be described later, the front and rear deck boards 3, 4 are installed at a height position lower than the upper surface of the lower back portion 5.

[0018] The front and rear deck boards 3, 4 are both intended to provide a flat surface on the floor portion 13 of the luggage compartment 10 for placing luggage, etc., and are made of, for example, synthetic resin and are flat plates that are approximately rectangular when viewed from above. Of the recesses 14a, 14b for storing items, the front deck board 3 is used to close the upper side of recess 14a on the front side of the vehicle. The rear deck board 4 is used to close the upper side of recess 14b on the rear side of the vehicle. A gripping portion 48 is appropriately provided at the rear of the rear deck board 4 so that the user can grip it with their hand when lifting the rear part of the rear deck board 4.

[0019] A pair of left and right deck board guide portions 6 are provided on both sides of the item storage recesses 14a, 14b (storage case 14) in the vehicle width direction as means for supporting both side edges of the front and rear deck boards 3, 4 in the vehicle width direction and laying them in a positioned state on the floor portion 13. However, in Figures 1 to 3, only the deck board guide portion 6 on the back side of the drawings (right side of vehicle 1) is shown, and the deck board guide portion 6 on the front side of the drawings is omitted.

[0020] 5, deck board guide portion 6 is configured so that a front region 6a on which the side edge of front deck board 3 rests, and a rear region 6b on which the side edge of rear deck board 4 rests, each extend in the longitudinal direction of the vehicle. Deck board guide portion 6 is further provided with first to third upwardly convex engaging protrusions 61 to 63, and an engaging recess 64.

[0021] The first engagement protrusion 61 is provided towards the front of the front region 6a. In contrast, the front deck board 3 has a notched recess 31 at its side edge, and the first engagement protrusion 61 is fitted in this notched recess 31. The side edge is placed on front region 6a so that first engaging protrusion 61 engages with pair of notched recesses 31. This allows front deck board 3 to be laid on floor portion 13 in the manner shown in Figure 3. The engagement between pair of notched recesses 31 and first engaging protrusion 61 prevents front deck board 3 from moving in the fore-and-aft direction of the vehicle and in the width direction of the vehicle. The front end of front deck board 3 is detachably attached to the underside of seat cushion portion 20 of rear seat 2, for example, using hook-and-loop fasteners 21 or the like.

[0022] Second engagement protrusion 62 is provided in a position near the rear of the vehicle of the location where front deck board 3 is arranged, and serves to form engagement recess 64. As will be described later with reference to Figure 6, engagement recess 64 is used to lean rear deck board 4 against rear seat 2. Note that second engagement protrusion 62 can also serve as a stopper that prevents front deck board 3 from shifting position toward the rear of the vehicle.

[0023] The third engagement protrusions 63 are provided in a position closer to the rear of the vehicle in the rear region 6b. In contrast, the rear deck board 4 has notched recesses 43 on its side edges, and the side edges are placed on the rear region 6b so that the third engagement protrusions 63 engage with these notched recesses 43. This allows the rear deck board 4 to be laid on the floor portion 13 in the manner shown in Figures 1, 4, and 5. The engagement between the pair of notched recesses 43 and the third engagement protrusions 63 prevents the rear deck board 4 from moving in the fore-and-aft direction and the width direction of the vehicle. However, this engagement is released when the rear portion of the rear deck board 4 is lifted. The pair of notched recesses 43 and the third engaging protrusion 63 described above correspond to a specific example of "position regulating means for a deck board" according to the present invention.

[0024] When the rear deck board 4 is laid on the floor portion 13 in the manner described above, the front portion of this rear deck board 4 is positioned overlapping the rear portion of the front deck board 3. When the rear portion of the rear deck board 4 is lifted up and the pair of notched recesses 43 and the third engaging protrusions 63 are disengaged, the front portion of the rear deck board 4 rests on the rear portion of the front deck board 3 and can then slide towards the front of the vehicle on the upper surface 30 of the front deck board 3. In the present embodiment, the front portion of the rear deck board 4 can slide until it abuts against the first engaging protrusions 61. The upper surface 30 of the front deck board 3 is preferably flat so that the sliding movement of the rear deck board 4 can be performed smoothly. Upper surface portion 30 of front deck board 3 corresponds to a specific example of "deck board slide support portion" according to the present invention.

[0025] Next, the operation of the deck board mounting structure A will be described.

[0026] 1 and 4, when the front and rear deck boards 3, 4 are laid on the floor portion 13, the front and rear deck boards 3, 4 cover the upper sides of the item storage recessed portions 14a, 14b, and luggage can be placed on these deck boards 3, 4. Because the front and rear deck boards 3, 4 are laid at a height lower than the lower back portion 5, the height dimension from the front and rear deck boards 3, 4 to the ceiling surface of the luggage compartment 10 is increased, which is preferable for ensuring luggage compartment capacity. As described above, front deck board 3 is prevented from moving in the fore-and-aft direction and in the vehicle width direction by the engaging action of the pair of notched recesses 31 and first engaging protrusions 61, and rear deck board 4 is prevented from moving in the fore-and-aft direction and in the vehicle width direction by the engaging action of the pair of notched recesses 43 and third engaging protrusions 63. This appropriately prevents the front and rear deck boards 3, 4 from shifting in position and from rattling while the vehicle is in motion.

[0027] With the front and rear deck boards 3 and 4 in the installed state, the user When the rear portion of the rear deck board 4 is lifted from the rear, outside the vehicle, the pair of notched recesses 43 and the third engaging protrusions 63 are disengaged, and a forward force resulting from the lifting acts on the rear deck board 4. As a result, as shown by the imaginary lines in FIG. 4 , the rear side of the rear deck board 4 rises, and at the same time, the front portion automatically slides toward the front of the vehicle on the upper surface 30 (deck board slide support portion) of the front deck board 3. Therefore, as the rear portion of the rear deck board 4 is lifted, the entire rear deck board 4 can be moved toward the front of the vehicle simply and quickly, facilitating the operation of widely opening up the upper portion of the item storage recess 14b. This also makes it easy to put items in and take items out of the item storage recess 14b, making it highly user-friendly.

[0028] There may be cases where a user lifts up the rear portion of the rear deck board 4 while aboard the vehicle 1. In this case, in this embodiment, even if a situation arises in which the user's hand or the like becomes pinched between the rear deck board 4 and the tailgate 11, the rear deck board 4 moves toward the front of the vehicle, as described above. Therefore, this movement prevents the user's hand or the like from becoming tightly pinched between the rear deck board 4 and the tailgate 11, thereby increasing the safety of the user.

[0029] 7 shows a comparative example. In this comparative example, a deck board 4e that opens and closes an item storage recess 14e in a floor portion 13 of a luggage compartment 10 of a vehicle 1e can swing up and down around a fixed swing fulcrum 90. Reference numeral 91 denotes a roof panel. In this comparison, when a user aboard the vehicle 1e lifts the rear of the deck board 4e, a gap 92 with a small width La is created between the deck board 4e and the back door 11e. Therefore, if the user's hand is placed in the gap 92, there is a risk that the hand will be strongly pinched. In contrast, in the present embodiment, the sliding action of the rear deck board 4 appropriately eliminates this risk.

[0030] In this embodiment, as shown in Fig. 6, the rear deck board 4 can be leaned against the rear seat 2. At this time, the lower end (front end) of the rear deck board 4 can be engaged with the engagement recess 64, appropriately preventing misalignment, thereby stabilizing the leaning state of the rear deck board 4. When the rear deck board 4 is set in this leaning state, the user does not need to hold the rear deck board 4 and both hands are free, making it even easier to load and unload luggage.

[0031] Additionally, in this embodiment, two deck boards, a front and a rear deck board 3, 4, are used as deck boards, and therefore the size and weight of each of these two deck boards 3, 4 are reduced. This makes each of these two deck boards 3, 4 even easier to handle. Furthermore, because the top surface portion 30 of the front deck board 3 is used as a portion that supports the front portion of the rear deck board 4 so that it slides (a slide support portion for the deck board), the configuration is rational and enables smooth sliding movement.

[0032] The present invention is not limited to the above-described embodiment, and the specific configuration of each part of the deck board mounting structure according to the present invention can be freely designed and modified in various ways within the intended scope of the present invention.

[0033] In the above-described embodiment, the deck board is divided into two, front and rear deck boards 3, 4, and the configuration intended by the present invention is applied to rear deck board 4, but the present invention is not limited to this. The deck board in the present invention may be divided into three or more sections, or may be configured using only one deck board. In the above-described embodiment, the front and rear deck boards 3 and 4 are respectively Although they are separate, they can also be connected by an appropriate connecting member. In this case, the connecting member can be, for example, a flexible member with ample length so as not to interfere with the sliding of the rear deck board 4, and the rear deck board 4 can be slid within this ample range.

[0034] In the above-described embodiment, the deck board position restriction means of the present invention employs a combination of a pair of notched recesses 43 provided in the rear deck board 4 and a pair of upwardly protruding third engagement protrusions 63 provided on the floor portion 13, but the present invention is not limited to this. For example, it is also possible to configure the third engagement protrusions 63 to protrude sideways, and for these third engagement protrusions 63 to engage with recesses provided on the underside of the rear deck board 4. Alternatively, it is also possible to provide an anti-slip portion on the upper surface of the upwardly protruding third engagement protrusions 63, and for the rear deck board 4 to be placed on this anti-slip portion. In essence, the deck board position restriction means may be configured to restrict the position of the deck board to prevent movement of the deck board in at least the fore-and-aft direction of the vehicle when the deck board is laid down, and to release this position restriction when the rear of the deck board is lifted up.

[0035] In the above-described embodiment, the upper surface 30 of the front deck board 3 is what is referred to as the deck board slide support portion in the present invention, but the present invention is not limited to this. The front deck board 3 can be omitted, and in that case, for example, the front region 6a of the deck board guide portion 6 can also be used as the deck board slide support portion. The slide support portion for the deck board may be configured, for example, by providing a convex pin on the side of the deck board, and supporting the convex pin by fitting it into a groove in the deck side trim that faces inward in the vehicle width direction. There are no specific limitations on the shape, size, or number of recesses for storing items provided in the floor of the luggage compartment. [Explanation of symbols]
