Description

冰箱 技术领域
本发明涉及一种冰箱。
背景技术
为了有效利用冰箱内的储藏空间，例如，在上下方向上排列设置了多个搁板，所述搁板用于对冷藏室内进行划分。此外，为了同样的目的，在对冷藏室的前表面开口进行打开关闭的隔热门的背面，在上下方向上排列设置了多个收纳架。
然而，在一般的冰箱中，所述搁板和收纳架的位置是固定的。另一方面，根据类型和包装形式，存储的物体具有不同的高度。因此，如果搁板或收纳架的高度位置固定，则会在被储藏物与配置在其正上方的搁板或收纳架之间，产生空区域。该空区域成为无法放置被储藏物的死空间(dead space)，因此，阻碍了冰箱内的储藏空间的有效利用。例如，在以下专利文献1、2中，公开了设想消除这样的冰箱内的死空间的技术。
专利文献1：日本特开2010－71577号公报
专利文献2：日本特开2005－43048号公报。
然而，上述专利文献中公开的技术都是调节冷藏室内的搁板的高度位置，而不是调节在隔热门的背面设置的收纳架的高度位置。由于在收纳架中也收纳了具有各种高度的被储藏物(例如，填充有饮料、液体调味品等的瓶子类等)，因此可能同样产生上述的死空间的问题。
发明内容
鉴于上述问题，本发明的目的在于，提供一种冰箱，其在隔热门的背面包括可调节高度位置的收纳架，以便于被储藏物的储藏(收纳)空间的进一步的有效利用。
用于解决问题的方案
为了解决上述问题，本发明的冰箱包括：
冰箱主体，包括储藏室；
隔热门，包括外装部、内装面板部和一对突出壁，所述外装部配置在所述冰箱主体的前表面侧，对所述储藏室进行打开关闭，所述内装面板部装配在所述外装部的背面侧开口区域，所述一对突出壁从所述内装面板部的两侧区域分别突出，在内部具有隔热材料的填充区域；
收纳架，设置在所述隔热门的背面侧，对被储藏物进行收纳；
一对肋条，从所述收纳架的两侧壁中的每一个向外方突出，并且在所述收纳架的高度方向上延伸；
一对收纳架高度位置调节部，分别安装到所述一对突出壁，并且包括可上下移动地嵌入所述肋条的轨道槽；以及
安装部，包括雄部和雌部，所述雄部从与所述突出壁相对的所述收纳架高度位置调节 部的端面突出，所述雌部装配在所述突出壁的内部并且可拆卸地安装所述雄部，
在所述肋条形成有轨道槽卡合单元，所述轨道槽卡合单元可与所述轨道槽的多个高度位置卡合。
此外，在本发明的冰箱中，
在所述隔热门的所述突出壁设有支承部，所述支承部对所述收纳架高度位置调节部进行支承，
所述支承部包括凹部，所述凹部向所述突出壁的内部侧凹陷，
在所述凹部形成有加宽部，所述加宽部向所述支承部的宽度方向外侧伸出，
所述收纳架高度位置调节部包括被收容凸部，所述被收容凸部从所述端面突出并收容于所述凹部，
在所述被收容凸部形成有卡合部，所述卡合部与所述加宽部卡合。
此外，在本发明的冰箱中，包括收纳架支承部，所述收纳架支承部包括：
插入片，可拆卸地插入到所述收纳架高度位置调节部的所述轨道槽内；以及
基部，与所述插入片相连，从底壁侧支承所述收纳架。
此外，在本发明的冰箱中，
所述肋条的所述轨道槽卡合单元包括：
第一凸部，形成在所述肋条的前壁；以及
第二凸部，形成在所述肋条的背壁，
多个第一凹部在所述轨道槽中的第一侧壁的高度方向上依次排列设置，所述多个第一凹部可与所述第一凸部卡合，
多个第二凹部在所述轨道槽中的第二侧壁的高度方向上依次排列设置，所述多个第二凹部可与所述第二凸部卡合，
沿着嵌入所述肋条的所述轨道槽来上下移动所述收纳架，而使所述第一凸部到达所述第一凹部中的任一个的高度位置并且使所述第二凸部到达所述第二凹部中的任一个的高度位置，由此，使所述第一凸部和所述第一凹部卡合且使所述第二凸部和所述第二凹部卡合，以将所述收纳架固定到预定的高度位置。
发明效果
根据本发明，设置了肋条和收纳架高度位置调节部，所述肋条从收纳架的侧壁向外方突出，所述收纳架高度位置调节部包括轨道槽，所述轨道槽嵌入肋条而发挥作为其向上下方向的移动路的作用，由此，能够使收纳架在上下方向上移动。由此，能够根据收纳在收纳架中的被储藏物的高度来适当调节收纳架的高度位置，因此，能够抑制产生死空间的情况。即，与收纳架的高度位置始终固定的以往的冰箱相比，能够有效利用设置在隔热门背面侧的被储藏物的储藏空间。此外，在安装部中，雄部可拆卸地安装到雌部，所述雄部设置在收纳架高度位置调节部侧，所述雌部设置在隔热门背面的突出壁内部，因此，能够将收纳架高度位置调节部附加到隔热门。由此，能够在不对已经提供的冰箱的隔热门的构造 进行变更的情况下，安装收纳架高度位置调节部。即，即使不设置具有专用构造的隔热门，也能够将收纳架高度位置调节部安装到通用的隔热门。其结果是，不会导致产品的成本上升。
此外，根据本发明，由于被收容凸部的卡合部与凹部的加宽部卡合，所以能够更牢固地固定收容架高度位置调节部。由此，能够可靠地防止收纳架高度位置调节部掉落等的情况。
此外，根据本发明，收纳架支承部的基部从轨道槽沿隔热门的宽度方向内侧延伸，支撑收纳架的底壁侧，因此，能够以预定的高度位置更可靠地支撑收纳架。
此外，根据本发明，当使收纳架移动到预定的高度位置时，肋条的第一凸部与轨道槽的第一凹部卡合，并且，肋条的第二凸部与轨道槽的第二凹部卡合，由此，能够固定收纳架。由于能够通过肋条的第一凸部和第二凸部、以及轨道槽的第一凹部和第二凹部这样的简单的构造，来调节收纳架的高度位置，因此能够防止冰箱的过度的成本增加。

具体实施方式
以下，参照附图来详细说明本发明的一个实施方式的冰箱1。此外，在说明本实施方式的冰箱1时，“上下”方向对应于冰箱1的高度方向，“左右”方向对应于冰箱1的宽度方向，“前后”方向对应于冰箱1的进深方向。此外，隔热门的各方向是根据隔热门对 储藏室进行关闭的状态来规定的。即，隔热门的高度方向(上下方向)对应于冰箱1的高度方向，隔热门的宽度方向(左右方向)对应于冰箱1的宽度方向，隔热门的进深方向(前后方向)对应于冰箱1的进深方向。
参照图1，对本实施方式的冰箱1的整体结构进行说明。在此，图1是冰箱1的整体立体图。如图1所示，本实施方式的冰箱1包括相当于冰箱主体的隔热箱体2。隔热箱体2包括钢板制的外箱、合成树脂制的内箱、以及发泡聚氨酯制的隔热材料，所述隔热材料填充在外箱与内箱之间形成的间隙内。
在隔热箱体2内部配设有隔热分隔壁，对冷藏室3、冷冻室4、蔬菜室5等进行划分。本实施方式的冰箱1从上起包括与冷藏室3、冷冻室4、蔬菜室5对应的多个储藏室。然而，各储藏室的配置顺序不限于此。此外，储藏室的数量也不限于此。
设置在隔热箱体2中的各储藏室的前表面是开口的。设置了隔热门，所述隔热门以可打开关闭的方式封闭这些开口。在隔热门10中，例如，冰箱的正面视图右端的上下端部通过铰链构件(未图示)可转动地支承于隔热箱体2，封闭冷藏室3的前表面开口部。此外，隔热门6配设成能够相对于隔热箱体2在前后方向上拉出，封闭冷冻室4的前表面开口部。同样地，隔热门7配设成能够相对于隔热箱体2在前后方向上拉出，封闭蔬菜室5的前表面开口部。
图1所示的隔热门10包括中空箱状的外装部11、内装面板部12和框体13，所述外装部11的背面侧(后面侧)是开口的，所述内装面板部12装配在外装部11的背面侧开口区域，所述框体13沿着内装面板部12的外周来安装，并且用于对装配有内装面板部12的外装部11内进行密封。在隔热门10内填充有隔热材料。
在装配有内装面板部12的隔热门10的背面侧，沿上下方向，隔开预定间隔，依次配置有多个收纳架20。尽管图1中示出了三个收纳架20，包括固定设置在最下部的收纳架，但是配置的收纳架20的数量不限于此。在各个收纳架20中，例如，收纳有饮料、液体调味品这样的瓶子类等的被储藏物。
此外，设置有长的突出壁121a、121b，其从内装面板部12的两侧区域(在隔热门10对冷藏室3进行关闭的状态下)向冷藏室3内侧(隔热门10的后方侧)突出。在突出壁121a、121b的内部(在后述的图9、10中，由附图标记122示出的区域)，形成有中空区域。在此也填充了隔热材料(隔热材料的填充区域)。此外，所述“侧区域”不限于内装面板部12的侧缘区域，而包括从内装面板部12的中央靠近隔热门10的宽度方向外侧(侧方侧)的所有区域。
一对收纳架高度位置调节部30a、30b分别安装到突出壁121a、121b的内侧，所述收纳架高度位置调节部对收纳架20的高度位置进行调节。此外，由于收纳架高度位置调节部30a、30b为同一构件，因此，以下，作为对收纳架高度位置调节部30a、30b双方进行示出的构件，称为“收纳架高度位置调节部30”。
接着，参照图2至图5，详细说明本实施方式的收纳架20的构造。图2是收纳架20 的立体图。此外，图3是收纳架20中包括的旋转体22的立体图。此外，图4是收纳架20的分解图，其示出了从收纳架20的主体取下了收纳架20中包括的旋转体22和锁定杆23的状态。此外，图5是装配了旋转体22和锁定杆23的状态下的收纳架20的局部立体图。
如图2所示，收纳架20在两侧壁20S1、20S2的每一个中包括一对肋条21a、21b(下文中，作为对肋条21a、21b双方进行示出的构件，称为“肋条21”。)。在本实施方式中，为了容纳内装面板部121的突出壁121a、121b，而在收纳架20的两侧壁20S1、20S2的前方侧区域中，设置了向收纳架20内侧凹陷的第一凹区域20S3、20S4。各肋条21分别配设在第一凹区域20S3、20S4中。
各肋条21从收纳架20的两侧壁20S1、20S2中的每一个向外方突出，并且在收纳架20的高度方向上延伸。此外，在各肋条21形成有轨道槽卡合单元，该轨道槽卡合单元能够与收纳架高度位置调节部30的后述的轨道槽31的多个高度位置卡合。虽然没有特别限定，但是本实施方式的轨道槽卡合单元包括第一凸部211和第二凸部212，所述第一凸部211形成在肋条21的前壁21F并且向肋条21的前方侧突出，所述第二凸部212形成在肋条21的背壁21B并且向肋条21的背方侧突出。图2所示的第一凸部211的数量为一个，但不限于此。此外，第一凸部211的位置也不限于图示的位置。同样，图2所示的第二凸部212的数量为一个，但不限于此。此外，第一凸部212的位置也不限于图示的位置。
此外，在收纳架20的两侧壁20S1、20S2(从第一凹区域20S3、20S4更向内侧凹陷的第二凹区域20S5、20S6)中的每一个中，设置有旋转体22。如图3所示，旋转体22包括基板221、小齿轮222、环状部223和多个爪部224。在此，小齿轮222设置在基板221的表面221F。此外，环状部223和爪部224设置在基板221的背面221B。
多个爪部224分别向环状部223的径向外侧突出，并且沿环状部223的外周排列设置。此外，各个爪部224包括倾斜面224S和垂直面224V，所述倾斜面224S倾斜使得爪部224的宽度随着朝向径向外侧而变窄，所述垂直面224V从环状部223的外周面垂直地立起。
此外，如图4和图5所示，一对锁定杆23设置在第二凹区域20S5、20S6中的每一个中，所述第二凹区域凹入设置在收纳架20的两侧壁中。本实施方式的各锁定杆23是配设于在同一凹区域中安装的旋转体22上方并且作用于旋转的旋转体22的构件。
在本实施方式中，所述第二凹区域20S5、20S6的上表面20S51、20S61是开口的(其中，在图4和图5中仅示出了第二凹区域20S6、开口上表面20S61)。以下，以第二凹区域20S6及其中装配的锁定杆23的构造为例进行说明，但第二凹区域20S5及其中装配的锁定杆23也具有同样的构造。
在锁定杆23中，其一端侧231以可旋转的方式轴支承于开口上表面20S61的前端部20S62，并且另一端侧232在能以一端侧231为轴进行转动的状态下容纳于开口上表面20S61(见图5)。然而，锁定杆23的位置不限于此。
此外，如图5所示，锁定杆23包括碰撞凸部233，所述碰撞凸部233从另一端侧232 的底部向下方突出，而与旋转体22的爪部224碰撞。碰撞凸部233包括一个面233S和另一个面233V，所述一个面233S与爪部224的倾斜面224S碰撞，所述另一个面233V与爪部224的垂直面224V碰撞并且是一个面233S的相对面。
碰撞凸部233的一个面233S倾斜成对应于爪部224的倾斜面224S。此外，碰撞凸部233的另一个面233V从锁定杆23的底部向下方垂直的延伸设置(垂直设置)成对应于爪部224的垂直面224V。
此外，优选地，收纳架20包括倾倒防止肋条24，其用于防止配置在该收纳架20正下的其他收纳架20中收纳的被储藏物的倾倒。如图6所示，本实施方式的倾倒防止肋条24从收纳架20的底壁20B向下方延伸设置。倾倒防止肋条24以覆盖被储藏物的至少上端前方区域和侧方区域的方式延伸。例如，当被储藏物因某种冲击而正要倾倒时，其上端与倾倒防止肋条24发生碰撞。由此，倾倒防止肋条24和被储藏物的例如上端发生干扰，结果是，防止了被储藏物的倾倒。
如后所述，收纳架20由收纳架高度位置调节部30以可上下移动的方式支承。因此，上下相邻设置的收纳架20中的、至少配置在上方侧的收纳架20能够移动到被储藏物的上端附近，所述被储藏物收纳在下方侧的收纳架20中。
即，即使在下方侧的收纳架20中不总是收纳高度一定的被储藏物的情况下，也能够通过上方侧的收纳架20的上下移动，来将倾倒防止肋条24配置在适当位置。由此，与在高度位置固定的以往的收纳架20中设置倾倒防止肋条24的情况相比，能够更有效地防止被储藏物的倾倒。
接着，参照图7和图8，详细说明收纳架高度位置调节部30的构造。图7是对收纳架高度位置调节部30的一部分进行示出的局部立体图。此外，图8是对装配了收纳架20的状态下的收纳架高度位置调节部30的一部分进行示出的局部图。
收纳架高度位置调节部30具有以可上下移动的方式支承收纳架20、并且调节其高度位置的功能。更具体地，收纳架高度位置调节部30包括：沿其高度方向延伸的轨道槽31、以及与轨道槽31大致平行地延伸的齿条32(见图7)。
在本实施方式中，在轨道槽的第一侧壁31S1中，分别凹入设置了向前方侧凹陷的多个第一凹部311。如图7所示，多个第一凹部311沿轨道槽31的高度方向，依次排列设置。图示的多个第一凹部311等间隔地排列，但不限于此。
此外，在轨道槽的第二侧壁31S2中，分别凹入设置了向背方侧凹陷的多个第二凹部312。如图7所示，多个第二凹部312沿轨道槽31的高度方向，依次排列设置。图示的多个第二凹部312等间隔地排列，但不限于此。
如图8所示，轨道槽31比收纳架20的肋条21宽，肋条21嵌入在轨道槽31内。在此状态下，使肋条21上下移动，其第一凸部211到达轨道槽31的第一凹部311的位置。由此，第一凸部211和第一凹部311卡合。同样，肋条21的第二凸部212到达轨道槽31的第二凹部312的位置。由此，第二凸部212和第二凹部312卡合。其结果是，收纳架20在 可经由肋条21在轨道槽31的延伸方向(上下方向)上移动的状态下，以预定的高度位置，被收纳架位置调节部30支承。
此外，本实施方式的收纳架高度位置调节部30的齿条32是与小齿轮222啮合的元件，所述小齿轮222设置在收纳架20的旋转体22。因此，齿条32设置在与小齿轮222相向的位置。虽然没有特别限制，但如图8所示，本实施方式的齿条32沿着收纳架高度位置调节部30的前方侧外壁33的高度方向而形成。
如图(例如图1)所示，本实施方式的一对收纳架高度位置调节部30a、30b与隔热门10的背面侧大致平行地设置。因此，如果是如下那样的收纳架20：所述收纳架20具有肋条21a、21b，所述肋条21a、21b包括第一凸部211、第二凸部212，其在高度位置的调节时起作用，其中，肋条21a、21b之间的距离大致一定，则即使是形状不同的收纳架20，也能够适应于收纳架高度位置调节部30。此外，即使根据需要而增加收纳架20的数量，也能够容易地进行将收纳架20装配到收纳架高度位置调节部30的作业。
接着，参照图9，对安装部40的构造进行说明，所述安装部40用于将收纳架高度位置调节部30安装到隔热门10。在此，图9(a)是从隔热门10内侧观察收纳架高度位置调节部30的局部图。此外，图9(b)是包括通过A-A′线对图9(a)所示的隔热门10进行剖切后的剖面的立体图(示出了安装部40的构造的立体图)。此外，在本实施方式中，由于突出壁121a和121b是同一构件，因此，作为对突出壁121a和121b双方进行示出的构件，称为“突出壁121”。
如图9(b)所示，安装部40包括雄部41和雌部42，所述雄部从与突出壁121相对的收纳架高度位置调节部30的端面34突出，所述雌部可拆卸地安装雄部41。本实施方式的雄部41为沉头螺钉。在此，沉头螺钉插入到贯通孔35，所述贯通孔35从收纳架高度位置调节部30的轨道槽31贯通到端面34。然而，雄部41的形态不限于此。作为雄部41的另一示例，列举了不穿过贯通孔35而以端面34为起点进行突出的肋条状的元件等。
此外，雌部42装配到突出壁121的内部122侧。本实施方式的雌部42是包括插入孔421的紧固件(fastener)，所述插入孔421插入雄部41。雄部41和雌部42配置成隔着突出壁121相向。由此，雌部42可拆卸地安装雄部41。然而，雌部42的形态也不限于此。此外，虽然没有特别限制，但优选的是，在将雌部42装配到突出壁121的内部122之后，向内部122填充隔热材料。
这样，雄部41可拆卸地安装到雌部42，所述雄部41设置在收纳架高度位置调节部30侧，所述雌部42设置在突出壁121侧。因此，能够将收纳架高度位置调节部30附加到隔热门10。由此，能够在不对已经提供的冰箱1的隔热门10的构造进行变更的情况下，安装收纳架高度位置调节部30。即，即使不设置专用的隔热门，也能够将收纳架高度位置调节部30安装到通用的隔热门。其结果是，不会导致产品的成本上升。
接着，参照图10，对支承部50的构造进行说明，所述支承部50设置在隔热门10的突出壁121，并且支承收纳架高度位置调节部30。在此，图10(a)是从背面侧观察隔热 门10的局部立体图。此外，图10(b)是包括通过B-B′线对图10(a)所示的隔热门10进行剖切后的剖面的立体图(示出了支承部50的构造的立体图)。此外，图10(c)是收纳架高度位置调节部30被支承部50支承的状态下的立体图。
如图10(b)所示，支承部50包括凹部51，所述凹部51向隔热门10的突出壁121的内部122侧凹陷。此外，在凹部51的前端侧，形成有加宽部53，所述加宽部53向支承部50的宽度方向外侧伸出，并且宽度相对于基端52扩展。然而，加宽部53的位置不限于凹部51的前端。
对此，如图10(c)所示，收纳架高度位置调节部30包括被收容凸部36，所述被收容凸部36从与突出壁121相对的端面34突出，并收容于凹部51。此外，在被收容凸部36的前端侧，形成有卡合部37，所述卡合部37向支承部50的宽度方向外侧伸出，并与加宽部53卡合。然而，卡合部37的位置不限于被收容凸部36的前端。
通过使卡合部37与加宽部53卡合，收纳架高度位置调节部30更牢固地固定到突出壁121。由此，能够可靠地防止收纳架高度位置调节部30掉落等的情况。此外，如果使凹部51中的基端52的宽度对应于收纳架20的肋条21的宽度，则能够将收纳架20的肋条21嵌入到收纳架高度位置调节部30脱离的凹部51中。即，能够通过对收纳架高度位置调节部30进行固定的凹部51来固定收纳架20。
接着，参照图11来说明收纳架支承部60，所述收纳架支承部60可拆卸地设置在收纳架高度位置调节部30的轨道槽31。在此，图11是包括收纳架支承部60的放大立体图。
如图11所示，收纳架支承部60包括插入片61和基部62，所述插入片可拆卸地嵌入到收纳架高度位置调节部30的轨道槽31内，所述基部从底壁侧支承收纳架20。本实施方式的基部62是从轨道槽31向隔热门10的宽度方向内侧延伸、并且与收纳架20的底壁20B接触的板状构件。然而，收纳架支承部60的形态不限于此。
根据本实施方式，由于这种构造的收纳架支承部60对收纳架20进行支承，因此能够以预定的高度位置，更可靠地支承收纳架20。此外，仅通过将插入片61插入到轨道槽31中的操作，就能够装配收纳架支承部60。因此，能够将收纳架支承部60简便地安装到轨道槽31。
[动作]
接着，参照图12，对收纳架20的高度位置的固定及其解除动作进行说明。在此，图12(a)与前述图8是相同的图，示出了固定到预定的高度位置的收纳架20。此外，图12(b)示出了预定的高度位置处的固定被解除的收纳架20。
首先，当收纳架20移动到预定的高度位置时，如图12(a)的左图所示，肋条21的第一凸部211和轨道槽的第一凹部311卡合，并且，肋条21的第二凸部212和轨道槽31的第二凹部312卡合。由此，收纳架20被收纳架高度位置调节部30的轨道槽31支承，固定在预定的高度位置处。
此时，如图12(a)的右下图所示，在肋条21的背壁21B中与第一凸部211相对的区 域21B1和轨道槽31的第二侧壁31S2之间，形成了间隙S1。此外，如图12(a)的右上图所示，在肋条21的前壁21F中与第二凸部212相对的区域21F1和轨道槽31的第一侧壁31S1之间，形成了间隙S2。
在该状态下，当如图12(b)的左图所示，使收纳架20倾斜(例如，使背方侧与前方侧相比上升)时，在肋条21和轨道槽31之间形成了间隙S1和S2，因此，如图12(b)的右上图所示，肋条21的上方侧向前方(图中右侧)移动，并且，如图12(b)的右下图所示，肋条21的下方侧向背方(图中左侧)移动。由此，在第一凸部211与第一凹部311的卡合被解除的同时，第二凸部212与第二凹部312的卡合被解除。其结果是，收纳架20的固定被解除。
固定被解除的收纳架20再次回到可上下移动的状态。接着，使收纳架20上下移动，第一凸部211与轨道槽31的另一第一凹部311卡合，第二凸部211与轨道槽31的另一第二凹部312卡合，由此，能够将收纳架20固定在不同的高度位置。
根据本实施方式，能够通过肋条21和轨道槽31的非常简单的构造来调节收纳架20的高度位置，因此能够避免产品的过度成本增加。此外，由于通过仅使收纳架20倾斜的作业，就能够解除收纳架20的固定，因此能够简便地进行收纳架20的高度调节。
然而，对收纳架20的固定进行解除的方式不限于图12所示的方式。例如，如果将第一凸部211设置在肋条21的上方侧，并且将第二凸部212设置在肋条21的下方侧，则能够通过使收纳架20的背方侧比前方侧降低(在与图12(b)相反的方向上，使收纳架20倾斜)，来对收纳架20的固定进行解除。此外，也可以是这以外的方式。
接着，参照图13来说明收纳架20中包括的旋转体22与锁定杆23的作用。在此，图13(a)是说明收纳架20上升时的旋转体22与锁定杆23的作用的图。此外，图13(b)是说明收纳架20下降时的旋转体22与锁定杆23的作用的图。
首先，当收纳架20上升时，小齿轮222旋转，所述小齿轮222与收纳架高度调节部30的齿条啮合。随之，经由基板221与小齿轮222连接的爪部224在图13(a)所示的箭头方向上旋转。此时，爪部224的倾斜面224S与一个面233S碰撞，所述一个面233S构成锁定杆23的碰撞凸部233。
如上所述，一个面233S与倾斜面224S对应地倾斜。此外，锁定杆23的包括碰撞凸部233的另一端侧232处于可将一端侧231作为轴进行转动的状态。因此，在倾斜面224S与一个面233S碰撞之后，倾斜面224S在一个面233S上滑动，并且通过倾斜面224S的碰撞压力，向上方推动锁定杆23的另一端侧232。
即，图13(a)中所示的爪部224的旋转动作不由锁定杆23停止。这样，爪部224可原样继续旋转，结果是，也不会妨碍收纳架20的动作。此外，通过旋转体22的小齿轮222(其与收纳架高度调节部30的齿条32啮合)的旋转，来辅助收纳架20的上升操作。
相对于此，当收纳架20下降时，小齿轮222和爪部224在图13(b)所示的箭头方向上旋转。此时，爪部224的垂直面224V与另一个面233V碰撞，所述另一个面233V与所述 一个面233S一起构成锁定杆23的碰撞凸部233。
如上所述，爪部224的垂直面224V从环状部223的外周面垂直地立起。此外，锁定杆23的另一个面233V从锁定杆23的底部向下方垂直设置。因此，与另一个面233V碰撞的垂直面224V的移动方向与另一个面233V大致正交。由此，垂直面224V和另一个面233V在物理上干扰。其结果是，垂直面224V的进一步的旋转受另一个面233V阻碍。与此对应地，小齿轮222的旋转也停止，因此停止了收纳架20的进一步的下降。
这样，通过锁定杆23的作用，停止了收纳架20的下降。因此，即使假设收纳架20的肋条21与收纳架高度调节部30的轨道槽31没有充分卡合，也能够通过爪部224与锁定杆23的作用，来防止收纳架20的掉落、或从轨道槽31的脱落等情况。
此外，当有意地想要降低收纳架20的高度位置时，进行提升锁定杆23的另一端侧232的操作。由此，避免了爪部224与碰撞凸部233的碰撞，不会阻碍图13(b)所示的爪部224的旋转。其结果是，小齿轮222能够在与齿条32啮合的同时进行旋转，而允许收纳架20的下降。
上面详细说明了本发明的实施方式。然而，以上说明是为了便于理解本发明，并不是为了限制本发明而记载。在不脱离本发明的主旨的情况下，在本发明中能够包括能变更、改进的那些方式。此外，在本发明中包括其等同物。
