JP 2006-306347 A Japanese Patent No. 4038775

ところで、ユーザは、荷室のボード上に荷物を置いたり、又置いた荷物を取り出す作業を、後部ドアを空けて車両後部側から行う。従って、荷物を載せるボードは、後端の位置が出来る限り車両後部側に迫り出していることが好ましく、このようにすることで、荷物を車両後部に近い位置に置くことが可能となり、荷物の出し入れを容易に出来る。一方、上記のように、ボードの高さ調整を、単なる回転動作により行う形式のものは、高さ調整に伴って移動するボードの先端の軌跡が円軌道となる。そのため、高さを調整した際に、ボードの前後方向の位置は円軌道によって一義的に定まってしまい、特に前後方向についての位置の自由度がほとんどない。 By the way, the user performs the work of placing the luggage on the board of the luggage compartment and taking out the placed luggage from the rear side of the vehicle with the rear door open. Therefore, it is preferable that the board on which the luggage is placed has the rear end position as close as possible to the rear side of the vehicle. In this way, the luggage can be placed close to the rear of the vehicle. Easy to put in and out. On the other hand, as described above, in the type in which the height adjustment of the board is performed by a simple rotation operation, the locus of the tip of the board that moves in accordance with the height adjustment becomes a circular orbit. Therefore, when the height is adjusted, the position in the front-rear direction of the board is uniquely determined by the circular orbit, and there is almost no degree of freedom in the position in the front-rear direction.

このような構成では、図１５に示すように、ボードＢを下段に位置させたとき、ボード全体が荷室の前部側に引き込まれた状態になることがほとんどである。すると、荷室の後壁（後部ドアが閉止される開口縁）３とボード後端４との間（図１５のＦ部）が空いてしまうから、そこに荷物が落ちてしまったり、また、荷物が落ちなくても、荷室の後壁から荷物までの距離が遠くなり、荷物の出し入れが行い難くなる。
本発明は上記のような事情に基づいて完成されたものであって、各取り付け段において、本体ボードの前後方向の位置を最適な位置に設定できるデッキボード及びデッキボード装置を実現させることを目的とする。 In such a configuration, as shown in FIG. 15, when the board B is positioned at the lower stage, the entire board is almost drawn into the front side of the cargo compartment. Then, since the space between the rear wall (opening edge at which the rear door is closed) 3 and the rear end 4 of the board (F part in FIG. 15) is vacant, the luggage falls there, Even if the luggage does not fall, the distance from the rear wall of the luggage compartment to the luggage is increased, making it difficult to take in and out the luggage.
The present invention has been completed based on the above circumstances, and an object of the present invention is to realize a deck board and a deck board device that can set the position of the main body board in the front-rear direction at an optimum position at each mounting stage. And

本発明（デッキボード）は、自動車の荷室において高さの異なる各取り付け段に取り付け可能とされたデッキボードであって、本体ボードと、この本体ボードの前側に第一ヒンジにより折り曲げ可能に連結された前部ボードと、前記前部ボードにおいて前記前部ボードに対して前後方向に相対移動可能に取り付けられた一、又は複数個のスライダと、前記スライダに取り付けられ荷室幅方向の両側壁に軸受される一対の軸部材と、を備えてなる。 The present invention (deck board) is a deck board that can be attached to each mounting stage having a different height in an automobile luggage compartment, and is connected to the front side of the main body board so that it can be bent by a first hinge. The front board, one or a plurality of sliders attached to the front board so as to be movable relative to the front board in the front-rear direction, and both side walls attached to the slider in the cargo compartment width direction And a pair of shaft members that are supported by each other.

本発明（デッキボード装置）は、請求項１ないし請求項６のいずれか一項に記載のデッキボードと、前記荷室の幅方向の両側壁に設けられ、前記軸部材を軸受けする軸受け部と、前記荷室の幅方向の両側壁に互いに高さを変えつつ複数個形成され、前記本体ボードに設けられた支持ピンを上から受け入れて支持することにより、中段を含む前記各取り付け段にて前記本体ボードを水平に支えるピンホルダと、を備え、前記中段では前記前部ボードが前記本体ボードと共に水平な状態にて支持されるデッキボード装置であって、前記軸部材を中心とする回転と前記スライダに対する相対移動とを前記前部ボードに行わせることにより、前記本体ボードを前記中段から各取り付け段へ移動させる構成であり、かつ前記本体ボードを前記中段の取り付け段からそれより低い次の取り付け段に移動させる場合には、前記前部ボードを前記スライダに対する相対移動によって車両後方側に移動させ、前記本体ボードを前記中段の取り付け段からそれより高い次の取り付け段に移動させる場合には、前記前部ボードを前記スライダに対する相対移動によって車両前側に相対移動させる構成とする。 The present invention (deck board device) includes a deck board according to any one of claims 1 to 6, and a bearing portion that is provided on both side walls in the width direction of the cargo compartment and that supports the shaft member. In each mounting stage including the middle stage, a plurality of both side walls in the width direction of the cargo compartment are formed while changing the height to each other, and receiving and supporting the support pins provided on the main body board from above. A pin holder that horizontally supports the main body board, and the middle board is a deck board device in which the front board is supported in a horizontal state together with the main body board, and the rotation around the shaft member and the The main board is moved from the middle stage to each mounting stage by causing the front board to move relative to the slider, and the main board is removed from the middle stage. When moving from the first step to the next lower mounting step, the front board is moved to the vehicle rear side by relative movement with respect to the slider, and the main body board is moved from the middle mounting step to the next higher step. When moving to the attachment stage, the front board is moved relative to the front side of the vehicle by moving relative to the slider.

これら発明では、前部ボード及び本体ボードがスライダに対して相対移動できるようにしてあり、本体ボードを中段からそれより高い次の取り付け段に移動させるときには、前部ボードがスライダとの相対移動により車両前側に移動する。その一方、本体ボードを中段からそれより低い次の取り付け段に移動させるときには、前部ボードがスライダとの相対移動により車両後方側に移動する。 In these inventions, the front board and the main board can be moved relative to the slider, and when the main board is moved from the middle stage to the next higher mounting stage, the front board is moved relative to the slider. Move to the front of the vehicle. On the other hand, when the main board is moved from the middle stage to the next lower mounting stage, the front board moves to the vehicle rear side by relative movement with the slider.

このような構成であれば、各取り付け段における本体ボードの位置（前後方向の位置）を、荷室後部の形状（側面方向から見たときの形状）に対応した位置に設定可能となる。というのも、通常、荷室後部の形状は、例えば、図７にて示すように、床面に近い下側が車両後方側にやや突き出ており、上側は車両前側にやや傾斜することが多い。これに対して、本発明では、中段より下側の段では、本体ボードの位置を車両後側寄りの位置にすることが可能となり、中段より上側の段では、本体ボードの位置を車両前側寄りの位置に出来るからである。 With such a configuration, the position of the main body board (position in the front-rear direction) in each mounting stage can be set to a position corresponding to the shape of the rear part of the luggage compartment (shape when viewed from the side surface direction). For example, as shown in FIG. 7, the shape of the rear part of the cargo compartment usually protrudes slightly toward the rear side of the vehicle and the upper side is slightly inclined toward the front side of the vehicle. On the other hand, in the present invention, the position of the main body board can be set closer to the rear side of the vehicle in the lower stage than the middle stage, and the position of the main body board is moved closer to the front side of the vehicle in the upper stage than the middle stage. Because it can be in the position.

The deck board DB mainly includes a main body board 50, a front board 60, and a pair of sliders 80. The main body board 50 is made of a synthetic resin thick plate, and its upper surface is a flat surface on which a load can be loaded. A pair of support pins 51 R and 51 L are provided on the rear portions of the left and right end faces of the main body board 50. The support pins 51R and 51L have their pin axes directed in the vehicle width direction, and project from the left and right end surfaces in the vehicle width direction. A handle 50 A is provided at the center of the upper rear portion of the main board 50.

前部ボード６０は本体ボード５０と同じく合成樹脂製の厚板よりなる。この前部ボード６０は図５の（Ａ）に示すように、本体ボード５０の前側に薄肉化（具体的には、前部ボード６０と本体ボード５０の境界部分を逆Ｖ字型に切り欠いて薄肉化）した第一ヒンジＨ１により連結されており、連結点Ｐを折り点にして両ボード５０、６０が折り曲げ自在な構成となっている。 The front board 60 is made of a synthetic resin thick plate like the main body board 50. As shown in FIG. 5A, the front board 60 is thinned on the front side of the main body board 50 (specifically, a boundary portion between the front board 60 and the main body board 50 is cut into an inverted V shape). The two boards 50 and 60 are configured to be foldable with the connecting point P as a folding point.

そして、これら前部ボード６０と本体ボード５０とを、図５の（Ａ）に示すようにボート角θを１８０度まで開くと、双方のボード５０、６０の上面同士が面一になる構成となっている。尚、以下の説明において、ボード角θが１８０度となるように開かれた状態を両ボード５０、６０の展開状態と呼ぶものとする。 When the front board 60 and the main board 50 are opened to a boat angle θ of 180 degrees as shown in FIG. 5A, the upper surfaces of both boards 50 and 60 are flush with each other. It has become. In the following description, the state where the board angle θ is opened to 180 degrees is referred to as the unfolded state of the boards 50 and 60.

そして、図６に示すように、前部ボード６０の幅方向の両側部には、それぞれ空洞状の前側収容部６５Ｒ、６５Ｌが形成され、又本体ボード５０の幅方向の両側部には、それぞれ空洞状の後側収容部５５Ｒ、５５Ｌが形成されている。前部ボード側の前側収容部６５Ｒ、６５Ｌは、前部ボード６０の前部寄りを位置を始端として車両後方向に延びており、前部ボード６０の後端面６９に開口している。一方、本体ボード５０側の後側収容部５５Ｒ、５５Ｌは、本体ボード５０の中央やや前側の位置を始端として車両前側に延びており本体ボード５０の前端面５９に開口している。 As shown in FIG. 6, hollow front housing portions 65 R and 65 L are formed on both sides in the width direction of the front board 60, respectively, and on both sides in the width direction of the main body board 50, respectively. Hollow rear housing portions 55R and 55L are formed. The front board-side front housing portions 65R and 65L extend in the vehicle rearward direction starting from the position near the front of the front board 60, and open to the rear end surface 69 of the front board 60. On the other hand, the rear housing portions 55R, 55L on the main body board 50 side extend to the front side of the vehicle starting from the position slightly in front of the center of the main body board 50 and open to the front end surface 59 of the main body board 50.

これら組をなす前後の収容部５５、６５は、次に説明するスライダ８０Ｒ、８０Ｌを前後移動可能に収容する収容空間Ｇを構成している。尚、スライダ８０Ｒ、８０Ｌは左右対称構造となっているので、以下スライダ８０Ｒ側を代表させて説明を行う。 The front and rear housing portions 55 and 65 that form these sets constitute a housing space G that houses sliders 80R and 80L described below so as to be movable back and forth. Since the sliders 80R and 80L have a left-right symmetrical structure, the slider 80R side will be representatively described below.

スライダ８０Ｒはスライダ前部８１と、スライダ後部８５とから分割構成されている。スライダ前部８１とスライダ後部８５は共に前後方向に長い形状をしており、第二ヒンジＨ２を介して折り曲げ可能に連結されている。尚、この第二ヒンジＨ２はスライダ前部８１のスライダ後部８５の境界部分を逆Ｖ字型に切り欠いて薄肉化することにより形成したものとなっている。 The slider 80R is divided into a slider front portion 81 and a slider rear portion 85. Both the slider front portion 81 and the slider rear portion 85 have a shape that is long in the front-rear direction, and are connected via a second hinge H2 so that they can be bent. The second hinge H2 is formed by thinning the boundary portion of the slider rear portion 85 of the slider front portion 81 by cutting it into an inverted V shape.

上記スライダ８０Ｒは、前部ボード６０の前側収容部６５Ｒと本体ボード５０の後側収容部５５Ｒとにより形成される収容空間Ｇ内を前後に移動できる。これにより、本発明の「前記前部ボードにおいて前記前部ボードに対して前後方向に相対移動可能に取り付けられた一、又は複数個のスライダ」が具現化されている。 The slider 80R can move back and forth in the accommodation space G formed by the front accommodation portion 65R of the front board 60 and the rear accommodation portion 55R of the main board 50. Thereby, the “one or a plurality of sliders attached to the front board so as to be relatively movable in the front-rear direction with respect to the front board” according to the present invention is embodied.

そして、スライダ８０Ｒを図５の（Ａ）に示す中間停止位置に停止させると、スライダ後部８５が、前部ボード６０の前側収容部６５Ｒと本体ボード５０の後側収容部５５Ｒとに跨るように位置する。 When the slider 80R is stopped at the intermediate stop position shown in FIG. 5A, the slider rear portion 85 straddles the front housing portion 65R of the front board 60 and the rear housing portion 55R of the main board 50. To position.

これにより、いわゆる閂型のロックがかかり、両ボード５０、６０は第一ヒンジＨ１を折れ点とする折れ曲がりを規制された状態になる。このように、スライダ後部（本発明の「閂部材」に相当）８５は、前側収容部（本発明の「受け部」に相当）及び後側収容部（本発明の「受け部」に相当）と共に、前部ボード６０と本体ボード５０を上面同士が面一となる一枚の板状にロックするロック機構を構成している。 As a result, a so-called saddle-shaped lock is applied, and the boards 50 and 60 are in a state in which the folding with the first hinge H1 as the folding point is restricted. As described above, the slider rear portion (corresponding to the “saddle member” of the present invention) 85 includes the front housing portion (corresponding to the “receiving portion” of the present invention) and the rear housing portion (corresponding to the “receiving portion” of the present invention). At the same time, a lock mechanism is configured to lock the front board 60 and the main body board 50 into a single plate whose upper surfaces are flush with each other.

尚、図５の（Ｂ）に示すように、スライダ８０Ｒのスライド前部８１の上面に、円弧状の位置決め突部８４を形成すると共に、前側収容部６５Ｒの内壁面には位置決め突部８４を受け入れ可能な嵌合凹部６６が形成されている。そして、図５の（Ａ）に示す中間停止位置では、位置決め突部８４が嵌合凹部６６に丁度嵌合して、スライダ８０Ｒを位置規制する構成となっている。 As shown in FIG. 5B, an arcuate positioning projection 84 is formed on the upper surface of the slide front portion 81 of the slider 80R, and the positioning projection 84 is formed on the inner wall surface of the front housing portion 65R. An acceptable fitting recess 66 is formed. At the intermediate stop position shown in FIG. 5A, the positioning protrusion 84 is just fitted into the fitting recess 66 to restrict the position of the slider 80R.

そして、本実施形態では、スライダ８０Ｒを図５の（Ａ）に示す中間停止位置からデッキボードＤＢに対して前後いずれかの方向に相対移動させると、スライダ後部８５の先端が前側収容部６５Ｒから外れるか、スライダ後部８５の後端が後側収容部５５Ｒから外れることで、上記ロックが解除される構成となっている。 In the present embodiment, when the slider 80R is moved relative to the deck board DB from the intermediate stop position shown in FIG. 5A in either the front or rear direction, the tip of the slider rear portion 85 is moved from the front housing portion 65R. The lock is released when the slider rear part 85 is detached or the rear end of the slider rear part 85 is detached from the rear housing part 55R.

尚、前側収容部６５Ｒの奥壁６８、後側収容部５５Ｒの奥壁５８はそれぞれストッパ壁となっている（図９、図１２参照）。これにより、スライダ８０Ｒは前側収容部６５Ｒの奥壁６８、又は後側収容部５５Ｒの奥壁５８に突き当たると、そこでデッキボードＤＢに対する相対移動が規制される構成となっている。 Note that the back wall 68 of the front housing portion 65R and the back wall 58 of the rear housing portion 55R are stopper walls, respectively (see FIGS. 9 and 12). Accordingly, when the slider 80R hits the back wall 68 of the front housing portion 65R or the back wall 58 of the rear housing portion 55R, the relative movement with respect to the deck board DB is restricted there.

また、スライダ後部８５にはコイルスプリング９０が止められている。このコイルスプリング９０は、本体ボード５０に一端側を止めており、スライド後部８５を含むスライダ８０Ｒの全体に、収容空間Ｇにおけるスライダ８０の位置に応じて引張方向、又は、反発方向への付勢力を作用させる構成となっている。 A coil spring 90 is fixed to the slider rear portion 85. The coil spring 90 is fixed to the main body board 50 at one end side, and the urging force in the tension direction or the repulsion direction is applied to the entire slider 80R including the slide rear portion 85 according to the position of the slider 80 in the accommodation space G. It is the structure which acts.

また、図６にて示すように、スライダ８０Ｒを構成するスライダ前部８１の前端部には、軸を車幅外側方向に向けてヒンジピン８３Ｒが取り付けられている。係るヒンジピン８３Ｒは前側収容部６５Ｒの壁面に形成される逃がし孔６７を幅方向に貫通しており、ピン先端を前部ボード６０の幅方向の両端面から突出させている。 Further, as shown in FIG. 6, a hinge pin 83R is attached to the front end portion of the slider front portion 81 constituting the slider 80R with the shaft facing the vehicle width outward direction. The hinge pin 83 R penetrates an escape hole 67 formed in the wall surface of the front housing portion 65 R in the width direction, and protrudes from the both ends of the front board 60 in the width direction.

３．デッキボードＤＢの操作方法
デッキボードＤＢを例えば、荷室２０の中段に取り付けるには、まず、図５の（Ａ）に示すように、前部ボード６０、本体ボード５０を共に水平にし、更に、スライダ８０Ｒ、８０Ｌを図５の（Ａ）に示す中間停止位置に移動させてやる。これにより、位置決め突部８４が嵌合凹部６６に嵌合すると共に、スライダ８０Ｒのスライダ後部８５が前側収容部６５Ｒと後側収容部５５Ｒに跨って止まり、またスライダ８０Ｌのスライダ後部８５が前側収容部６５Ｌと後側収容部５５Ｌに跨って止まる。 3. How to operate the deck board DB To attach the deck board DB to, for example, the middle stage of the luggage compartment 20, first, as shown in FIG. 5A, both the front board 60 and the body board 50 are leveled. The sliders 80R and 80L are moved to the intermediate stop position shown in FIG. As a result, the positioning projection 84 is fitted into the fitting recess 66, the slider rear portion 85 of the slider 80R is stopped across the front housing portion 65R and the rear housing portion 55R, and the slider rear portion 85 of the slider 80L is front housing. It stops across the portion 65L and the rear housing portion 55L.

これにて、デッキボードＤＢは、両ボード５０、６０の連結点となる第一ヒンジＨ１を折れ点とする折れ曲がりが規制された状態（すなわちロック）になり、一枚の板状になる。尚、また、コイルスプリング９０は幾らか伸びた状態にあって、スライダ８０Ｒ、８０Ｌに対して引っ張り方向の付勢力を作用させた状態にある。尚、この付勢力はスライダ８０Ｒ、８０Ｌのガタつきを抑える程度の極弱い付勢力である。 As a result, the deck board DB is in a state in which bending with the first hinge H1 serving as a connection point between the boards 50 and 60 is restricted (that is, locked), and becomes a single plate. In addition, the coil spring 90 is in a somewhat extended state, and a biasing force in the pulling direction is applied to the sliders 80R and 80L. This urging force is an extremely weak urging force that suppresses rattling of the sliders 80R and 80L.

あとは、一枚の板状になったデッキボードＤＢを後部開口１７から荷室内に入れつつ、デッキボードＤＢの左右のヒンジピン８３Ｒ、８３Ｌを、左右のデッキサイドトリム２５Ｒ、２５Ｌに設けられたヒンジピンホルダ３１にそれぞれ取り付け、デッキボードＤＢの左右の支持ピン５１Ｒ、５１Ｌを左右のデッキサイドトリム２５Ｒ、２５Ｌに設けられた中段の支持ピンホルダ３５にそれぞれ取り付けてやればよい。これにより、デッキボードＤＢを、図２、図７に示すように、荷室２０の中段にセット出来る。 The left and right hinge pins 83R and 83L of the deck board DB are connected to the left and right deck side trims 25R and 25L while the single deck board DB is put into the luggage compartment from the rear opening 17. The left and right support pins 51R and 51L of the deck board DB may be attached to the middle support pin holders 35 provided on the left and right deck side trims 25R and 25L, respectively. As a result, the deck board DB can be set in the middle of the luggage compartment 20 as shown in FIGS.

次に、中段に取り付けられたデッキボードＤＢを上段に調整するには、本体ボード５０の取っ手５０Ａを引き上げて、一枚の板状にロックされた本体ボード５０とデッキボードＤＢを、ヒンジピン８３Ｒ、８３Ｌを軸（中心）に上側に回転させてやり、本体ボード５０の支持ピン５１Ｒ、５１Ｌを中段の支持ピンホルダ３５からそれぞれ外してやる。 Next, in order to adjust the deck board DB attached to the middle stage to the upper stage, the handle 50A of the main body board 50 is pulled up, and the main body board 50 and the deck board DB locked in a single plate shape are connected to the hinge pin 83R, The support pins 51R and 51L of the main body board 50 are respectively removed from the support pin holder 35 in the middle stage by rotating 83L about the axis (center).

そして、本体ボード５０の支持ピン５１Ｒ、５１Ｌが外せたら、次に、本体ボード５０を車両前側に軽く押し込んでやる。すると、スライダ８０Ｒ、８０Ｌはその位置に留まる（ヒンジピン８３Ｒ、８３Ｌが軸受けされた状態にあるのでスライダは動けない）ものの、前部ボード６０と本体ボード５０は、車両前側に押し込まれから、スライド前部８１の上面に形成される位置決め突部８４から、前側収容部６５Ｒの内壁面に形成される嵌合凹部６６がまず外れ、その後、前部ボード６０及び本体ボード５０が車両前側に移動する。 When the support pins 51R and 51L of the main board 50 can be removed, the main board 50 is then lightly pushed into the front side of the vehicle. Then, although the sliders 80R and 80L remain in their positions (the sliders cannot move because the hinge pins 83R and 83L are in a state of being supported), the front board 60 and the main body board 50 are pushed into the front side of the vehicle before the slide. The fitting recess 66 formed on the inner wall surface of the front housing portion 65R is first removed from the positioning projection 84 formed on the upper surface of the portion 81, and then the front board 60 and the main body board 50 move to the front side of the vehicle.

すると、前部ボード６０及び本体ボード５０との間に起こる相対移動により、両スライダ８０Ｒ、８０Ｌのスライダ後部８５が本体ボード５０側の後側収容部５５Ｒ、５５Ｌの奥側に差し込まれてゆく。そのため、前部ボード６０側の前側収容部６５Ｒ、６５Ｌに対するかかりが浅くなってゆき、やがて両スライダ８０Ｒ、８０Ｌのスライダ後部８５の先端が、前側収容部６５Ｒ、６５Ｌからほぼ同時に外れる。これにより、スライダ８０Ｒ、８０Ｌのスライダ後部８５によるロックが解除する。 Then, due to the relative movement that occurs between the front board 60 and the main body board 50, the slider rear portions 85 of both the sliders 80R and 80L are inserted into the rear sides of the rear housing portions 55R and 55L on the main body board 50 side. As a result, the depth of the front housing portions 65R and 65L on the front board 60 side becomes shallower, and the tips of the slider rear portions 85 of both sliders 80R and 80L eventually come off from the front housing portions 65R and 65L almost simultaneously. Thereby, the lock | rock by the slider rear part 85 of the sliders 80R and 80L is cancelled | released.

そして、本体ボード５０が車両前側に更に押し込まれてゆくと、それに追随してスライダ８０Ｒ、８０ＬはデッキボードＤＢに対して相対的な移動を続けるから、スライダ後部８５は後側収容部５５Ｒ、５５Ｌの奥方に、更に差し込まれてゆく。やがて、スライダ後部８５の全体が、本体ボード５０の後側収容部５５Ｒ、５５Ｌ内に収まり、スライダ後部８５の後端が後側収容部５５Ｒ、５５Ｌの奥壁５８に突き当たる状態になる。 Then, as the main body board 50 is further pushed into the front side of the vehicle, the sliders 80R, 80L continue to move relative to the deck board DB, and therefore the slider rear portion 85 has the rear housing portions 55R, 55L. It will be inserted further into the back. Eventually, the entire slider rear portion 85 is accommodated in the rear housing portions 55R and 55L of the main body board 50, and the rear end of the slider rear portion 85 comes into contact with the rear wall 58 of the rear housing portions 55R and 55L.

かくして、スライダ８０Ｒ、８０ＬとデッキボードＤＢとの相対移動が規制されると、その後、本体ボード５０を車両前側に押し込む力は、ヒンジピン８３Ｒ、８３Ｌを軸（中心）として車両前側に前部ボード６０を回転させるように作用する。また、この段階では、既に、前部ボード６０と本体ボード５０との間のロックは解除した状態にあり、前部ボード６０と本体ボード５０は折れ点となる第一ヒンジＨ１を軸に折り曲げ可能となっている。 Thus, when the relative movement between the sliders 80R and 80L and the deck board DB is restricted, the force that pushes the main body board 50 toward the front side of the vehicle thereafter causes the front board 60 to move toward the front side of the vehicle with the hinge pins 83R and 83L as the axis (center). Acts to rotate. Further, at this stage, the lock between the front board 60 and the main body board 50 has already been released, and the front board 60 and the main body board 50 can be bent around the first hinge H1 serving as a break point. It has become.

以上のことから、その後、更に、本体ボード５０が車両前側に押し込まれると、前部ボード６０だけがヒンジピン８３Ｒ、８３Ｌを軸（中心）として図８のＲ方向に回転し、次第に姿勢を起してゆく。そして、本体ボード５０は前部ボード６０に対するボード角θを小さくすることで水平な姿勢を保ちつつ、次第に、高さを上げてゆく。 From the above, when the main body board 50 is further pushed into the front side of the vehicle, only the front board 60 rotates in the R direction of FIG. 8 with the hinge pins 83R and 83L as axes (center), and gradually takes a posture. Go. The main body board 50 gradually increases its height while maintaining a horizontal posture by reducing the board angle θ with respect to the front board 60.

そして、前部ボード６０が一定角回転すると、図１０に示すように、前部ボード６０の後端面６９と本体ボード５０の前端面５９が面当たりした状態になる。後は、本体ボード５０のボード後部に設けられる左右の支持ピン５１Ｒ、５１Ｌを、左右のデッキサイドトリム２５Ｒ、２５Ｌに形成される上段の支持ピンホルダ３４にそれぞれ上から嵌合させてやれよい。 When the front board 60 rotates by a certain angle, the rear end surface 69 of the front board 60 and the front end surface 59 of the main body board 50 come into contact with each other as shown in FIG. Thereafter, the left and right support pins 51R and 51L provided at the rear part of the main body board 50 may be fitted from above to the upper support pin holders 34 formed on the left and right deck side trims 25R and 25L, respectively.

これにて、本体ボード５０を、図３、図１０に示す上段にセットできる。この上段では、図１０にて示すように、スライダ前部８１が、本体ボード５０の前側を支えるので、本体ボード５０は、ボード上面がフラットになる水平な姿勢で安定する。 Thus, the main body board 50 can be set in the upper stage shown in FIGS. In this upper stage, as shown in FIG. 10, the slider front portion 81 supports the front side of the main body board 50, so that the main body board 50 is stabilized in a horizontal posture in which the board upper surface is flat.

そのため、本体ボード５０の上面に問題なく荷物を置くことが可能である。尚、この上段において、両スライダ８０Ｒ、８０Ｌのスライダ後部８５は後側収容部５５Ｒ、５５Ｌの奥壁５８に突き当たった状態にあり、またコイルスプリング９０は全長を短くした状態にあってスライダ８０Ｒ、８０Ｌに対して車両前側への付勢力を作用させた状態にある。 Therefore, it is possible to place a load on the upper surface of the main body board 50 without any problem. In this upper stage, the slider rear portions 85 of both sliders 80R and 80L are in contact with the rear wall 58 of the rear housing portions 55R and 55L, and the coil spring 90 is in a state in which the overall length is shortened and the sliders 80R, 80R, The urging force to the front side of the vehicle is applied to 80L.

また、上段にある本体ボード５０を中段に戻すには、操作を逆に辿ってやればよい。すなわち、まず、取っ手８７を手で掴んで本体ボード５０を持ち上げ、本体ボード５０の支持ピン５１Ｒ、５１Ｌを、上段の支持ピンホルダ３４から外してやる。その後、本体ボード５０を車両後方に引き込んでやる。 Further, in order to return the main body board 50 in the upper stage to the middle stage, the operation may be followed in reverse. That is, first, the main body board 50 is lifted by grasping the handle 87, and the support pins 51R and 51L of the main body board 50 are removed from the upper support pin holder 34. Thereafter, the main body board 50 is pulled back to the vehicle.

これを行うと、まず、前部ボード６０がヒンジピン８３Ｒ、８３Ｌを軸（中心）として図１０のＳ方向に回転してゆく。そして、前部ボード６０が一定角回転すると、図８にて示すように本体ボード５０と前部ボード６０が展開状態となる。すると、前部ボード６０側の前側収容部６５Ｒ、６５Ｌと本体ボード５０側の後側収容部５５Ｒ、５５Ｌが互いに向かい合って整合するので、両スライダ８０Ｒ、８０Ｌのスライダ後部８５が、前側収容部６５Ｒ、６５Ｌに対して進入可能となる。尚、このとき、コイルスプリング９０は、スライダ８０Ｒ、８０Ｌに対して反発力、すなわち車両前側へ押し込む力を作用させる。 When this is done, first, the front board 60 rotates in the S direction in FIG. 10 with the hinge pins 83R and 83L as axes (centers). Then, when the front board 60 rotates by a certain angle, the main body board 50 and the front board 60 are in the unfolded state as shown in FIG. Then, the front housing portions 65R, 65L on the front board 60 side and the rear housing portions 55R, 55L on the main board 50 side face each other and align, so that the slider rear portions 85 of both sliders 80R, 80L are aligned with the front housing portion 65R. , 65L can be entered. At this time, the coil spring 90 applies a repulsive force to the sliders 80R and 80L, that is, a force that pushes the sliders 80R and 80L toward the vehicle front side.

それ以降、更に、本体ボード５０を車両後方に引き込んでゆくと、両スライダ８０Ｒ、８０Ｌのスライダ後部８５の前端が、次第に前部ボード６０の前側収容部６５Ｒ、６５Ｌに進入してゆく。これにて、スライダ後部８５によるロックが再びかかり、両ボード５０、６０は第一ヒンジＨ１を軸とした折れ曲がりを規制された状態に戻る。 Thereafter, when the main body board 50 is further pulled toward the rear of the vehicle, the front ends of the slider rear portions 85 of both sliders 80R and 80L gradually enter the front housing portions 65R and 65L of the front board 60. As a result, the slider rear portion 85 is locked again, and the boards 50 and 60 return to a state in which the bending around the first hinge H1 is restricted.

あとは、本体ボード５０を更に、車両後方に引き込みながら、支持ピン５１を、中段の支持ピンホルダ３５に嵌合させてやればよく、これにて、本体ボード５０を図２、図７に示す中段に復帰できる。尚、このとき、スライダ８０Ｒ、８０Ｌは、図５の（Ａ）に示す中間停止位置に戻り、スライド前部８１の上面に形成される位置決め突部８４が、前側収容部６５Ｒの内壁面に形成される嵌合凹部６６に、再び嵌合する。 After that, the main body board 50 is further retracted toward the rear of the vehicle, and the support pins 51 may be fitted into the middle support pin holder 35. The main body board 50 is then moved to the middle stage shown in FIGS. Can return to At this time, the sliders 80R and 80L return to the intermediate stop position shown in FIG. 5A, and a positioning protrusion 84 formed on the upper surface of the slide front portion 81 is formed on the inner wall surface of the front housing portion 65R. The mating recess 66 is fitted again.

次に、中段に取り付けられたデッキボードＤＢを下段に調整するには、上段への調整時と同様に、本体ボード５０の取っ手５０Ａを引き上げて、一枚の板状にロックされた本体ボード５０とデッキボードＤＢを、ヒンジピン８３Ｒ、８３Ｌを軸（中心）に上側に回転させてやり、本体ボード５０の支持ピン５１Ｒ、５１Ｌを中段の支持ピンホルダ３５からそれぞれ外してやる。 Next, in order to adjust the deck board DB attached to the middle stage to the lower stage, similarly to the adjustment to the upper stage, the handle 50A of the main body board 50 is pulled up, and the main body board 50 locked in a single plate shape. The deck board DB is rotated upward with the hinge pins 83R and 83L as axes (centers), and the support pins 51R and 51L of the main body board 50 are removed from the support pin holder 35 in the middle stage.

そして、本体ボード５０の支持ピン５１Ｒ、５１Ｌが外せたら、次に、本体ボード５０を車両後方に引き込んでやる。すると、スライダ８０Ｒ、８０Ｌはその位置に留まる（ヒンジピン８３Ｒ、８３Ｌが軸受けされた状態にあるためスライダは動けない）ものの、前部ボード６０と本体ボード５０は車両後方に引かれるから、スライド前部８１の上面に形成される位置決め突部８４から、前側収容部６５Ｒの内壁面に形成される嵌合凹部６６がまず外れ、その後、前部ボード６０及び本体ボード５０が車両後側に移動する。 When the support pins 51R and 51L of the main body board 50 can be removed, the main body board 50 is then pulled toward the rear of the vehicle. Then, the sliders 80R and 80L remain in their positions (the sliders cannot move because the hinge pins 83R and 83L are supported), but the front board 60 and the main body board 50 are pulled toward the rear of the vehicle. The fitting recess 66 formed on the inner wall surface of the front housing portion 65R is first disengaged from the positioning protrusion 84 formed on the upper surface of 81, and then the front board 60 and the main body board 50 move to the vehicle rear side.

すると、前部ボード６０及び本体ボード５０との間に起こる相対移動により、両スライダ８０Ｒ、８０Ｌが前部ボード６０側の前側収容部６５Ｒ、６５Ｌの奥側に差し込まれてゆく。そのため、本体ボード５０側の後側収容部５５Ｒ、５５Ｌに対するかかりが浅くなってゆき、やがて、両スライダ８０Ｒ、８０Ｌのスライダ後部８５の後端が後側収容部５５Ｒ、５５Ｌからほぼ同時に外れ、これにより、スライダ８０Ｒ、８０Ｌのスライダ後部８５によるロックが、まず解除する（図１１参照）。 Then, due to the relative movement that occurs between the front board 60 and the main body board 50, both sliders 80R and 80L are inserted into the back side of the front housing parts 65R and 65L on the front board 60 side. Therefore, the depth of the rear housing portions 55R and 55L on the main body board 50 side becomes shallow, and eventually the rear ends of the slider rear portions 85 of both the sliders 80R and 80L come off from the rear housing portions 55R and 55L almost simultaneously. Thus, the lock by the slider rear portion 85 of the sliders 80R and 80L is first released (see FIG. 11).

また、このロック解除の後、スライダ前部８５の前端が、前部ボード６０の前側収容部６５Ｒ、６５Ｌの奥壁６８に突き当たる状態になる。かくして、スライダ８０Ｒ、８０ＬとデッキボードＤＢとの相対移動が規制される結果、本体ボード５０をそれ以上、車両後方側に引けない状態になる。 Further, after the unlocking, the front end of the slider front portion 85 comes into contact with the rear walls 68 of the front housing portions 65R and 65L of the front board 60. Thus, as a result of the relative movement between the sliders 80R, 80L and the deck board DB being restricted, the main body board 50 cannot be pulled further to the vehicle rear side.

この段階では既に、前部ボード６０と本体ボード５０との間のロックは解除した状態にあり、前部ボード６０と本体ボード５０は折れ点となる第一ヒンジＨ１を軸に、折り曲げ可能となっている。そのため、その後、本体ボード５０を持つ手の力を緩めてやれば、前部ボード６０だけがヒンジピン８３Ｒ、８３Ｌを軸（中心）に図１１のＳ方向に回転し、姿勢を倒してゆく。そして、本体ボード５０は前部ボード６０に対するボード角θを大きくすることで水平な姿勢を保ちつつ、自重により次第に高さを下げていく。 At this stage, the lock between the front board 60 and the main body board 50 has already been released, and the front board 60 and the main body board 50 can be bent around the first hinge H1 as a break point. ing. Therefore, after that, if the hand holding the main body board 50 is loosened, only the front board 60 rotates in the S direction in FIG. 11 with the hinge pins 83R and 83L as axes (center), and the posture is brought down. The main body board 50 gradually decreases its height by its own weight while maintaining a horizontal posture by increasing the board angle θ with respect to the front board 60.

後は、本体ボード５０のボード後部に設けられる左右の支持ピン５１Ｒ、５１Ｌを、左右のデッキサイドトリム２５Ｒ、２５Ｌに形成される下段の支持ピンホルダ３６にそれぞれ上から嵌合させてやればよく、これにて、本体ボード５０を、図４、図１３に示す下段にセットできる。 Thereafter, the left and right support pins 51R and 51L provided on the rear part of the main body board 50 may be fitted to the lower support pin holders 36 formed on the left and right deck side trims 25R and 25L, respectively, from above. Thus, the main body board 50 can be set in the lower stage shown in FIGS.

そして、この下段において、前部ボード６０は車両後方に下降傾斜した姿勢となるものの、本体ボード５０はボード上面がフラットな姿勢となる。そのため、本体ボード５０の上面に問題なく荷物を置くことが可能である。尚、この下段において、両スライダ８０Ｒ、８０Ｌのスライダ前部８５は前側収容部６５Ｒ、６５Ｌの奥壁６８に突き当たった状態にあり、またコイルスプリング９０は全長を長くした状態にあって、スライダ８０Ｒ、８０Ｌに対して引張力、すなわち車両後方側へ引き込み力を作用させる。 And in this lower stage, although the front board 60 becomes the attitude | position which inclined downward to the vehicle rear, the main body board 50 becomes an attitude | position with a flat board upper surface. Therefore, it is possible to place a load on the upper surface of the main body board 50 without any problem. In this lower stage, the slider front portions 85 of both sliders 80R and 80L are in contact with the rear wall 68 of the front housing portions 65R and 65L, and the coil spring 90 is in a state where the overall length is increased, and the slider 80R , 80L, a pulling force, that is, a pulling force is applied to the vehicle rear side.

また、下段にある本体ボード５０を中段に戻すには、操作を逆に辿ってやればよい。すなわち、まず、取っ手８７を手で掴んで本体ボード５０を持ち上げて、本体ボード５０の支持ピン５１Ｒ、５１Ｌを下段の支持ピンホルダ３４から外すと共に、両ボード５０、６０を図１１に示す展開状態に戻してやる。 Further, in order to return the main body board 50 in the lower stage to the middle stage, the operation may be followed in reverse. That is, first, the handle 87 is grasped by hand and the main body board 50 is lifted to remove the support pins 51R and 51L of the main body board 50 from the lower support pin holder 34, and the boards 50 and 60 are brought into the unfolded state shown in FIG. I'll bring it back.

これにより、前部ボード６０側の前側収容部６５Ｒ、６５Ｌと本体ボード５０側の後側収容部５５Ｒ、５５Ｌが、互いに向かい合って整合するので、両スライダ８０Ｒ、８０Ｌのスライダ後部８５が、前側収容部６５Ｒ、６５Ｌに対して進入可能となる。尚、このとき、コイルスプリング９０は、スライダ８０Ｒ、８０Ｌに対して、車両後方側へ引き込み力を作用させる。 As a result, the front housing portions 65R and 65L on the front board 60 side and the rear housing portions 55R and 55L on the main board 50 side face each other and align, so that the slider rear portions 85 of both sliders 80R and 80L are accommodated in the front housing. It becomes possible to enter the portions 65R and 65L. At this time, the coil spring 90 applies a pulling force to the sliders 80R and 80L toward the vehicle rear side.

その後、本体ボード５０を車両前方に押し込んでゆくと、両スライダ８０Ｒ、８０Ｌのスライダ後部８５の前端が、本体ボード５０の後側収容部５５Ｒ、５５Ｌに進入してゆく。かくして、スライダ後部８５によるロックが再びかかり、両ボード５０、６０は第一ヒンジＨ１を軸とした折れ曲がりを規制された状態になる。 Thereafter, when the main body board 50 is pushed forward, the front ends of the slider rear portions 85 of both the sliders 80R and 80L enter the rear housing portions 55R and 55L of the main body board 50. Thus, the lock by the slider rear portion 85 is again applied, and the boards 50 and 60 are in a state in which the bending with the first hinge H1 as an axis is restricted.

あとは、本体ボード５０を更に、車両前側に押し込みながら、支持ピン５１Ｒ、５１Ｌを、中段の支持ピンホルダ３５に嵌合させてやれよく、これにて、本体ボード５０を図２、図８に示す中段に復帰できる。尚、このとき、スライダ８０Ｒ、８０Ｌは図５の（Ａ）に示す中間停止位置に戻り、スライド前部８１の上面に形成される位置決め突部８４が、前側収容部６５Ｒの内壁面に形成される嵌合凹部６６に、再び嵌合する。 After that, the support pins 51R and 51L may be fitted into the middle support pin holder 35 while pushing the main body board 50 further toward the front of the vehicle, and the main body board 50 is shown in FIGS. It can return to the middle stage. At this time, the sliders 80R and 80L return to the intermediate stop position shown in FIG. 5A, and a positioning projection 84 formed on the upper surface of the slide front portion 81 is formed on the inner wall surface of the front side accommodation portion 65R. Refit to the fitting recess 66.

以上説明したように、本実施形態では、本体ボード５０を前後に押し引きするだけの簡単な操作で、本体ボード５０を高さ調整できるから、使い勝っ手がよく商品性が高い。 As described above, in the present embodiment, the height of the main body board 50 can be adjusted by a simple operation of simply pushing and pulling the main body board 50 back and forth.

また、本実施形態のものは、本体ボード５０の調整段数が３段となっているので、荷室２０を上下に仕切るパターンにバリエーションを持たすことが可能であり、この点も効果的である。 Moreover, since the thing of this embodiment has the adjustment | control stage number of the main body board 50, it can have a variation in the pattern which partitions the luggage compartment 20 up and down, and this point is also effective.

また、本実施形態では、前部ボード６０及び本体ボード５０がスライダ８０Ｒ、８０Ｌに対して相対移動できるようにしてあり、本体ボード５０を中段から上段（それより高い次の取り付け段）に移動させるときには、前部ボード６０がスライダ８０Ｒ、８０Ｌとの相対移動により車両前側に移動する。その一方、本体ボード５０を中段から下段（それより低い次の取り付け段）に移動させるときには、前部ボード６０がスライダ８０Ｒ、８０Ｌとの相対移動により車両後方側に移動する。 In this embodiment, the front board 60 and the main body board 50 can be moved relative to the sliders 80R and 80L, and the main body board 50 is moved from the middle stage to the upper stage (the next higher mounting stage). Sometimes, the front board 60 moves to the vehicle front side by relative movement with the sliders 80R and 80L. On the other hand, when the main body board 50 is moved from the middle stage to the lower stage (next lower mounting stage), the front board 60 moves to the vehicle rear side by relative movement with the sliders 80R and 80L.

このような構成であれば、各取り付け段における本体ボード５０の位置（前後方向の位置）を、荷室後部の形状（側面方向から見たときの形状）に対応した位置に設定可能となる。というのも、通常、荷室後部の形状は、例えば、図７にて示すように、床面に近い下側が車両後方側にやや突き出ており、上側は車両前側にやや傾斜することが多い。これに対して、本発明では、中段より下側の段では、本体ボード５０の位置を車両後側寄りの位置にすることが可能となり、中段より上側の段では、本体ボード５０の位置を車両前側寄りの位置に出来るからである。 With such a configuration, the position of the main body board 50 (the position in the front-rear direction) in each mounting stage can be set to a position corresponding to the shape of the rear part of the cargo compartment (the shape when viewed from the side surface direction). For example, as shown in FIG. 7, the shape of the rear part of the cargo compartment usually protrudes slightly toward the rear side of the vehicle and the upper side is slightly inclined toward the front side of the vehicle. On the other hand, in the present invention, the position of the main body board 50 can be set closer to the rear side of the vehicle in the lower stage than the middle stage, and the position of the main body board 50 is set in the upper stage of the middle stage. This is because it can be in a position closer to the front side.

また特に、本実施形態では、図７、図１３に示すように、少なくとも中段、下段において、本体ボード５０の後端が荷室２０の後壁２０Ａに近い位置にある。このようにしておけば、荷室内の後部側にも無理なく荷物Ｚを置くことが可能となり、荷物Ｚの取り出し口となる後部開口１７から荷物Ｚまでの距離が必然的に近くなる。そのため、荷物Ｚの出し入れが行い難くなり、本体ボード５０の取り付け位置として最適である。 In particular, in the present embodiment, as shown in FIGS. 7 and 13, the rear end of the main body board 50 is at a position close to the rear wall 20 A of the luggage compartment 20 at least in the middle and lower stages. In this way, it is possible to place the luggage Z without difficulty on the rear side of the luggage compartment, and the distance from the rear opening 17 serving as the luggage Z outlet to the luggage Z is necessarily reduced. For this reason, it becomes difficult to put in and out the luggage Z, and it is optimal as an attachment position of the main body board 50.

尚、中段では、両ボード５０、６０が展開状態となり、デッキボードＤＢの全長（車両前後方向の長さ）が最大になるから必然的に、本体ボード５０の後端の位置が荷室２０の後壁２０Ａに近い位置になる。これに対し下段では、両ボード５０、６０が折れた状態となり、中段に比べてデッキボードＤＢの全長が短くなるにも拘わらず、本体ボード５０の後端の位置を、中段と同じ位置を保つことが出来るのは、上記した相対移動の作用によるものに他ならない。 In the middle stage, the boards 50 and 60 are unfolded, and the total length of the deck board DB (the length in the vehicle front-rear direction) is maximized. The position is close to the rear wall 20A. On the other hand, in the lower stage, both boards 50 and 60 are in a folded state, and the position of the rear end of the main board 50 is kept at the same position as the middle stage even though the total length of the deck board DB is shorter than that in the middle stage. What can be done is nothing but the above-mentioned action of relative movement.

また、本実施形態では、スライダ８０Ｒ、８０Ｌが、両ボード５０、６０を一枚の板状にロックする閂部材としての機能を兼用している。そのため、このような閂部材を専用に形成する場合に比べて、部品点数少なく装置を構成することが可能となる。 In the present embodiment, the sliders 80R and 80L also serve as a hook member that locks the boards 50 and 60 into a single plate. Therefore, it is possible to configure the apparatus with a reduced number of parts compared to the case where such a flange member is formed exclusively.

また、本実施形態では、スライダ８０Ｒ、８０Ｌ、コイルスプリング９０などのデッキボードＤＢの上下移動機構を構成する機構部品がデッキボードＤＢ側に対して全て集約されている。そのため、荷室２０のデッキサイドトリム２５Ｒ、２５Ｌには、単に、デッキボードＤＢに設けられたピン類を下支えするホルダのみ形成すればよく、デッキサイドトリム２５Ｒ、２５Ｌ側の形状をシンプルにできる。具体的には、デッキサイドトリム２５Ｒ、２５Ｌの表面に大きな凹凸が出来ず、見栄えがよい。また、デッキボードＤＢの上下移動機構を構成する機構部品の一部をデッキサイドトリム２５Ｒ、２５Ｌに内蔵する必要がないため、その分、荷室空間を拡大することができる。 Further, in the present embodiment, all the mechanical components that constitute the vertical movement mechanism of the deck board DB such as the sliders 80R and 80L and the coil spring 90 are integrated on the deck board DB side. Therefore, the deck side trims 25R and 25L of the luggage compartment 20 may be formed only with holders for supporting the pins provided on the deck board DB, and the shape of the deck side trims 25R and 25L can be simplified. Specifically, the surface of the deck side trims 25R and 25L cannot be greatly uneven, and the appearance is good. In addition, since it is not necessary to incorporate some of the mechanical parts constituting the vertical movement mechanism of the deck board DB in the deck side trims 25R and 25L, the cargo space can be expanded accordingly.

しかも、スライダ８０Ｒ、８０Ｌ、コイルスプリング９０などの機能部品は全て、デッキボードＤＢに内蔵されており、これらが外部に露出されない構成となっているから、デッキボードＤＢそれ自体についても見栄えもよい。 In addition, all the functional components such as the sliders 80R and 80L and the coil spring 90 are built in the deck board DB and are not exposed to the outside. Therefore, the deck board DB itself may look good.

また、本実施形態では、荷室２０の側壁を構成するデッキサイドトリム２５Ｒ、２５Ｌに設けたヒンジピンホルダ３１、支持ピンホルダ３４〜３６に対して、デッキボードＤＢ側のヒンジピン８３、支持ピン５１Ｒ、５１Ｌを乗せるだけの取り付け構造となっているから、取り付けられたデッキボードＤＢを持ち上げるだけで荷室２０から取り外すことが出来、この点も、効果的である Further, in the present embodiment, the hinge pin 83 and the support pins 51R and 51L on the deck board DB side with respect to the hinge pin holder 31 and the support pin holders 34 to 36 provided on the deck side trims 25R and 25L constituting the side wall of the luggage compartment 20. Since it has a mounting structure that can only be loaded, it can be removed from the luggage compartment 20 simply by lifting the mounted deck board DB, which is also effective.

また、本実施形態では、デッキボードＤＢ内にコイルスプリング９０を内蔵させている。このコイルスプリング９０は、図１０に示す下段、図１３に示す上段において、スライダ８０Ｒ、８０Ｌに対し、これを図５の（Ａ）、図７に示す中間停止位置に戻す方向への付勢力を作用させる。従って、デッキボードＤＢを中段に戻す操作を行うと、その過程で、スライダ８０Ｒ、８０Ｌを中間停止位置に向けて確実に動かすことが可能となり、この点も効果的である。 In this embodiment, a coil spring 90 is built in the deck board DB. The coil spring 90 applies a biasing force in a direction to return the sliders 80R and 80L to the intermediate stop positions shown in FIGS. 5A and 7 in the lower stage shown in FIG. 10 and the upper stage shown in FIG. Make it work. Therefore, when the operation of returning the deck board DB to the middle stage is performed, the sliders 80R and 80L can be reliably moved toward the intermediate stop position in the process, which is also effective.
