200302065 玖、發明說明 (發明說明應敘明：發明所屬之技術領域、先前技術、內容、實施方式及圖式簡單說明） ㈠明所屬之技術領域 本發明係關於一種設置在展示櫃各層中之架子裝置， 尤其是關於一種架子裝置，其中架板可被儲存在架子 支持件上，並且架板可被向前推出。 ㈡先前技術 日本實用新型專利公告No.2529051中所揭示之架子 裝置被公認爲開放式展示櫃用之架子裝置。 此架子裝置具有放.置貨物之架板。而且，架子裝置具 有支持架板用之架子支持件，其可使架板傾斜，因而使 架板前端降低。另外，架子裝置具有用來連接架板到架 子支持件用之連接件。此連接件可連接架板到架子支持 件，使架板可在深度方向上對架子支持件滑動。 當貨物被重新供應到儲存於架子支持件上之架板上 時，工作由下列所敘述之程序執行。首先，架板前端由 手握住，並且向前推出。然後，待被重新供應之貨物被 置於架板上。隨後，被重新供應貨物之架板的前端被手 握住，並且被推回。因而，已被重新供應貨物之架板可 再度被固定到架子支持件上，因此完成再供應作業。 揭示於上述公告中之架子裝置被使用於單層展示櫃 (設置有一個架子裝置之展示櫃）。但是，此架子裝置可 被使用於多層展示櫃（設置有多層架子裝置之展示櫃） 對多層之展示櫃，有時視儲存貨物之種類，數量等 之需要，必須使垂直相鄰之架板之間的空間被改變，或 200302065 者許多層之架子裝置被改變。爲了執行此種改變之工作， 首先，架子支持件之鎖部必須在以手握住架子裝置之 時而從架柱上的鉤孔上移除。因此，架子裝置整個從多層 之展示櫃移除。隨後，架子裝置被移動到所需高度之位 置，並且架子支持件之鎖部再次被鎖到架柱上的鉤孔。以 此安裝/移除作業之時，架板之間的空間可被改變，或者 架板之層數可被增加或減少。 然而對上述之架子裝置而言，因爲架板及架子支持件 彼此經由連接件固定以避免被分離，整個架子裝置之重 量相當高，因而架子裝置之安裝/移除作業爲相當粗重的 工作。而且，因爲架子裝置之架板在橫向上很長，架板有 時候在安裝/移除作業時會扭曲。因此，難以將連接到架 板右側及左側之架子支持件鎖到在右側及左側相同高 度之鉤？L。 ㈢發明內容 本發明基於上述狀況而被發展出來，並且因而其一 個目的在提供一種展示櫃之架子裝置，其中人工可被 減少，並且架子支持件可以在執行工作時很容易地安 裝在適當位置，以改變架子之間的空間，或架子之層 數。 本發明之第1方面提供一種展示櫃之架子裝置，其 包括有：放置貨物之架板，支持架板用之架子支持件， 以及連接架板到架子支持件且使架板在深度方向上滑 動之連接件，其中連接件及架板中之一者具有鎖件，而 另一者則具有鎖溝，其可使鎖件被鎖住在其上並且從 200302065 其中解鎖。 依照本發明之第1方面，當架板被儲放在展示櫃時， 鎖件被鎖到鎖溝。因此，架板由連接件而被固定到架子 支持件。 另一方面，當架子之間的空間或架子之層數被改變 時，鎖件從鎖溝被解鎖。因此，架板從連接件及架子支 持件上移除，使架子裝置被分離成兩個部份。因而，架 板之安裝工作以及架子支持件之安裝工作可分別地執 行，使改變架子裝置之配置位置的工作很容易進行，並 且架子支持件之定位可以正確地執行。 本發明上述及其他目的及特徵及優點可由下列之詳 細說明及附圖明顯之。 ㈣實施方式 第1到7C圖顯示本發明展示櫃之架子裝置之一個實 施例。 首先，展示櫃之構造將參照第1圖而簡單解釋之。顯 示於此圖之展示櫃爲多層式開放展示櫃1 (隨後稱爲展 示櫃1)，其中有5個架子裝置2垂直地配置在其內。而 且，瓶裝貨物A被置於架子裝置2上。當瓶裝貨物A必 須保持冷卻時，展示櫃1之內部可由圖中未顯示之冷卻 設備冷卻之。 其次，設置在展示櫃1之5層架子裝置2之構造將參 照第2圖到第7 A，7 B及7 C圖而解釋。架子裝置2具有 可置放貨物A之架板2 1，位於兩端之架子支持件2 2， 以及連接架板2 1到架子支持件2 2用之連接件。 200302065 架板2 1有架體2 1 1爲平坦盒狀，其上面爲開放，並 且貨物A被置放在架體211上。而且，在架體211之前 方設置有一個橫向伸設之前方塊2 1 2。另外，在前方塊 2 1 2之上表面設置有線狀護件2 1 3。此線狀護件2 1 3可防 止架體211上之貨物A掉落。 如第3,5,7A，7B，及7C圖所示，在架體211之背面 設有一個鎖線2 1 4。 此鎖線2 1 4在橫向上伸設於架體 2 1 1前側之整個長度上，並且鎖線2 1 4之每一端部被彎 曲成L型，因而可被鎖到鎖溝2 3 2 c及從鎖溝2 3 2 c上解 鎖，下面將敘述之。而且，如第3, 5, 6A，及6B圖所示， 在前方塊2 1 2之下表面之每一端，設有一個橫剖面被彎 曲成L型之放鬆件2 1 5。此放鬆件2 1 5可樞轉地支持一 個以螺栓2 1 5 b固定到前方塊2 1 2之背面上的基板 215a。而且，在直立部中，兩個爪215c及215d被形成 於前方及後方。當前爪2 1 5 c向內轉時，如第6 B圖所示， 後爪2 1 5 d與一個後面將敘述之止件2 2 2接觸，並且向 外推而將止件2 22打開。 架子支持件2 2是由板子所形成，並且如第2，4，及5 圖所示，在伸設在展示櫃1之深度方向中。而且，架子 支持件22之上及下端被向內彎，並且上彎曲部221支 持架體2 1 1之底面。上彎曲部2 2 1從後晴朝向則而向 下傾斜。因此，支持在上彎曲部2 2 1上之架板2 1亦如 上彎曲部2 2 1 —樣朝向前方。使架板2 1依照此方式傾 斜之時，當最前方之貨物A被售出之時，下一個後方之 貨物A可依序地滑動向前方。 -10- 200302065 在架板2 1之背面，設置有一個夾板（未顯示）被配合 到上彎曲部2 2 1中。當架板2 1被支持在架子支持件2 2 上之時，如第7 A圖所示，夾板可防止架板2 1之後部從 架子支持件2 2上掉落。而且，當架板2 1從架子支持件 2 2滑向前之時，如第7 B圖所示，架板2 1之夾住狀態可 被放鬆。 在架子支持件2 2之前側設置有止件2 2 2。止件2 2 2 是由伸設在深度方向上之板彈簧所形成。而且，在止件 2 2 2之深度方向上的中間部，形成有一個止部222 a朝向 內側彎曲成L型。並且，在止部222a之頂端形成有一 個接觸部2 2 2 b向外伸出。 如第5及6A圖所示，止部222a通常由止件222之彈 力而鎖到凹孔2 3 2b，隨後將敘述。另一方面，當放鬆 件215轉動時，如第6B圖所示，接觸部2 22b向外移動 抵住彈力，因而止部222a之鎖住狀態可被放鬆。 在架子支持件22之後端，鉤2 2 2 c被形成在上部份及 下部份上。鉤222c被鎖到豎立於展示櫃1中之架柱（未 顯示），因而整個架子裝置2可被固定到展示櫃1。具體 上，架柱形成有許多配置在垂直方向上之鉤孔（未顯示）， 並且將鉤2 2 2 c鎖到預定之鉤孔時，架子裝置2可在預 定高度上被固定到展示櫃1。 連接件23包括有伸設於深度方向之滑動機構231， 以及一個連接板2 3 2。滑動機構231具有一個固定板231a， 一個可移動板231b，以及一個設置在固定板231a與可 移動板2 3 1 b之間的中間板2 3 1 c。而且，軸承2 3 1 d被插 -11- 200302065 入中間板2 3 1 c與固定板2 3 1 a之間，並且軸承2 3 1 d被插 入中間板2 3 1 c與可移動板2 3 1 b之間。因而，可移動板 231b可在深度方向上滑動，如第4圖中之雙箭頭所示。 連接板2 3 2之前側被彎曲成逆C型，並且凹孔2 3 2b 被形成在彎曲部232a之內側角落部。止部222a被鎖到 此凹孔2 3 2 b，並且從此凹孔23 2b中解鎖。而且，垂直 伸設之鎖溝2 3 2 c被形成在靠近連接板2 3 2之彎曲部2 3 2 a 之位置，如第4，7 A，7 B及7 C圖所示。此鎖溝2 3 2 c之 構造將詳細地解釋。鎖溝23 2 c被形成爲首先從連接板 2 3 2之之上端向下延伸，進一步地從下端稍微向前方延 伸，並且進一步從前端向下延伸。因而，即使鎖到鎖溝 2 3 2 c之鎖線2 1 4被直直地向上拉之時，鎖線2 1 4並不會 從鎖溝2 3 2 c中脫離，如第7 A圖所示。因此，將鎖線2 i 4 鎖到鎖溝2 3 2 c之時，架板2 1可被連接到連接板2 3 2。 滑動機構2 3 1之固定板2 3 1 a以螺栓（未顯示）等而被 固定到架子支持件22之內表面，並且連接板232被固 定到可移動板2 3 1 b。因而，架板2 1經由連接件2 3而被 固定到架子支持件22，並且架板21可由滑動機構231 而在深度方向上進行滑動，如第7A，7B及7C圖所示。 其次，改變架子裝置2之配置位置的工作，主要將 參照第7A，7B及7C圖而敘述之。當架板21被置放在架 子支持件2 2上之時，如第7 A圖所示，鎖線2 1 4被鎖到 鎖溝2 3 2 c，並且如第6 A圖所示，止部2 2 2 a被鎖到凹孔 232b。因而，架板21如第1圖所示之最上層的架板21 一樣，被儲放在展示櫃1上。 200302065 當架子裝置2之配置位置被改變時，首先放鬆件2 1 5 之前爪2 1 5 c被握住而成如第6 A圖所示之狀態。然後， 前爪2 1 5 c向內轉動如第6 A圖中之虛線箭頭符號所示 者。因此，爪21 5d可被移到與接觸部2 2 2 b進行接觸，並 且接觸部222b可被推動且向外移動而抵住止件2 2 2的彈 力。因此，如第6 B圖所示，止部2 2 2 a從凹孔2 3 2 b中 離開，使滑動機構2 3 1之可移動板2 3 1 b可向前移動。 其次，架板21由手握住，並且被推向前方。因而，連 到架板2 1之連接板2 3 2可向前移動，從而架板2 1被推 出向前，如第7 B圖所示（與第1圖頂部所顯示之第2架 子裝置2 —樣）。隨後，鎖線214沿著鎖溝2 3 2c被拉上， 如第7 C圖中之實線箭頭所示者。因此，架板2 1可如第 7 C圖所示而被移除。 在架板2 1從連接件2 3分離之後，架子支持件2 2之 鉤22 2c被鉤到其他預定之鉤孔，以改變架子支持件22 之配置位置到一個新.的位置。隨後，架板2 1之鎖線2 1 4 再度配合到鎖溝2 3 2 c ,以將架板2 1連接到連接件2 3。 然後，架板2 1被推動朝向架子支持件2 2。因而，架板 2 1可在架子支持件2 2上滑動。而且，止件2 2 2之止部 222a再度被鎖到凹孔2 3 2 b中，因此使滑動機構231在 深度方向中之滑動可被調整。當上述工作完成時，架板 2 1被支持在架子支持件2 2上，並且改變架子支持件2 2 之配置位置的工作被完成。 依此實施例，當架子支持件2 2之配置位置改變時， 架板2 1可從連接件2 3上移除，使架板之安裝工作以及 -13- 200302065 架子支持件之安裝工作可分別地執行。因此，使改變架 子裝置之配置位置的工作很容易進行，並且架子支持 件之定位可以正確地執行。 ㈤圖示簡單說明 第1圖爲開放式展示櫃之側視圖； 第2圖架子裝置之一般透視圖； 第3圖是顯示架板之背面之透視圖； 第4圖是顯示架板，架子支持件，及連接件之組合 的透視圖；

prior art, the content, the embodiments, and a brief description of the drawings) The technical field to which the invention belongs The present invention relates to a shelf provided in each layer of a display cabinet The device, in particular, relates to a shelf device in which a shelf plate can be stored on a shelf support and the shelf plate can be pushed forward. ㈡Prior art The shelf device disclosed in Japanese Utility Model Patent Publication No. 2529051 is recognized as a shelf device for an open display cabinet. The shelf device has a shelf plate on which goods are placed. Further, the shelf device has a shelf support for supporting the shelf plate, which can tilt the shelf plate, thereby lowering the front end of the shelf plate. In addition, the rack device has a connection member for connecting the shelf plate to the shelf support member. This connector connects the shelf plate to the shelf support, allowing the shelf plate to slide against the shelf support in the depth direction. When the goods are re-supplied to the shelf stored on the shelf support, the work is performed by the procedure described below. First, the front of the shelf is held by the hand and pushed forward. The goods to be re-supplied are then placed on the shelf. Subsequently, the front end of the shelf to be re-supplyed was held by the hand and pushed back. Thus, the shelf board which has been re-supplyed goods can be fixed to the shelf support member again, thereby completing the re-supply operation. The shelf device disclosed in the above bulletin is used in a single-layer display cabinet (a display cabinet provided with a shelf device). However, this shelf device can be used in multi-layer display cabinets (display cabinets equipped with multi-layer shelf devices). For multi-layer display cabinets, depending on the type and quantity of stored goods, it is necessary to make The space between the rooms was changed, or the shelves of many floors were changed. In order to perform such a change, first, the lock portion of the shelf supporting member must be removed from the hook hole on the shelf post while holding the shelf device with the hand. As a result, the shelving unit is completely removed from the multi-level display case. Subsequently, the rack device is moved to a desired height position, and the lock portion of the rack support member is locked to the hook hole on the rack post again. During this installation / removal operation, the space between the shelves can be changed, or the number of shelves can be increased or decreased. However, for the above-mentioned shelf device, since the shelf plate and the shelf support member are fixed to each other via a connecting member to avoid being separated, the weight of the entire shelf device is quite high, so the installation / removal of the shelf device is a relatively heavy work. Also, because the shelf plate of the shelf device is long in the lateral direction, the shelf plate is sometimes distorted during installation / removal operations. Therefore, it is difficult to lock the shelf support members connected to the right and left sides of the shelf plate to the hooks of the same height on the right and left sides? L. ㈢ SUMMARY OF THE INVENTION The present invention has been developed based on the above-mentioned circumstances, and therefore an object thereof is to provide a shelf device of a display cabinet in which labor can be reduced, and a shelf support member can be easily installed in an appropriate position when performing work, To change the space between shelves, or the number of shelves. A first aspect of the present invention provides a shelf device for a display cabinet, comprising: a shelf plate for placing goods, a shelf support member for supporting the shelf plate, and a shelf plate connected to the shelf support member and sliding the shelf plate in a depth direction One of the connecting pieces has a locking piece and the other has a locking groove, and the other has a locking groove, which can lock the locking piece and unlock it from 200302065. According to the first aspect of the present invention, when the shelf board is stored in the display case, the lock member is locked to the lock groove. Therefore, the shelf plate is fixed to the shelf support member by the connection member. On the other hand, when the space between the shelves or the number of shelves is changed, the lock is unlocked from the lock groove. Therefore, the shelf plate is removed from the connection member and the shelf support, so that the shelf device is separated into two parts. Therefore, the installation work of the shelf board and the installation work of the shelf support member can be performed separately, so that the work of changing the arrangement position of the shelf device can be easily performed, and the positioning of the shelf support member can be performed correctly. The above and other objects and features and advantages of the present invention will be apparent from the following detailed description and the accompanying drawings. ㈣Embodiments Figs. 1 to 7C show an example of the rack device of the display cabinet of the present invention. First, the structure of the display case will be explained briefly with reference to FIG. 1. The display case shown in this figure is a multi-layer open display case 1 (hereinafter referred to as a display case 1) in which five rack units 2 are vertically arranged therein. Moreover, the bottled goods A are placed on the shelf device 2. When the bottled goods A must be kept cool, the inside of the display case 1 may be cooled by a cooling device not shown in the figure. Next, the structure of the five-story shelf device 2 provided in the display case 1 will be explained with reference to Figs. 2 to 7A, 7B, and 7C. The shelf device 2 has a shelf plate 21 for holding the goods A, shelf support members 2 2 at both ends, and a connection member for connecting the shelf plate 21 to the shelf support member 22. 200302065 The shelf plate 2 1 has a shelf body 2 1 1 having a flat box shape, the upper surface of which is open, and the cargo A is placed on the shelf body 211. Furthermore, a laterally extending front block 2 1 2 is provided in front of the frame body 211. A wire-shaped guard 2 1 3 is provided on the upper surface of the front block 2 1 2. This linear guard 2 1 3 prevents the cargo A on the frame body 211 from falling. As shown in Figs. 3, 5, 7A, 7B, and 7C, a lock wire 2 1 4 is provided on the back of the frame 211. This lock wire 2 1 4 extends across the entire length of the front side of the frame 2 1 1 in the transverse direction, and each end of the lock wire 2 1 4 is bent into an L shape, so it can be locked to the lock groove 2 3 2 c and from The lock groove 2 3 2 c is unlocked, which will be described below. Moreover, as shown in Figs. 3, 5, 6A, and 6B, at each end of the lower surface of the front block 2 1 2, there is provided a loose member 2 1 5 whose cross section is bent into an L-shape. This release member 2 1 5 pivotally supports a base plate 215a fixed to the back of the front block 2 1 2 with bolts 2 1 5 b. Further, in the upright portion, two claws 215c and 215d are formed in the front and rear. When the front claw 2 1 5 c is turned inward, as shown in FIG. 6B, the rear claw 2 1 5 d is in contact with a stopper 2 2 2 which will be described later, and pushed outward to open the stopper 2 22. The shelf support member 22 is formed of a board, and is extended in the depth direction of the display case 1 as shown in Figs. 2, 4, and 5. Further, the upper and lower ends of the shelf supporting member 22 are bent inward, and the upper curved portion 221 supports the bottom surface of the frame body 2 1 1. The upper curved portion 2 2 1 is inclined downward from the rear clear direction. Therefore, the shelf plate 2 1 supported on the upper curved portion 2 2 1 also faces forward like the upper curved portion 2 2 1. When the shelf plate 21 is tilted in this way, when the frontmost cargo A is sold, the next rearward cargo A can be sequentially slid forward. -10- 200302065 On the back of the shelf plate 21, a splint (not shown) is provided to be fitted into the upper curved portion 2 2 1. When the shelf plate 21 is supported on the shelf support member 2 2, as shown in FIG. 7A, the splint prevents the rear portion of the shelf plate 21 from falling off the shelf support member 2 2. Further, when the shelf board 21 is slid forward from the shelf support member 22, as shown in Fig. 7B, the clamped state of the shelf board 21 can be relaxed. A stopper 2 2 2 is provided on the front side of the shelf support member 2 2. The stopper 2 2 2 is formed by a leaf spring extending in the depth direction. Furthermore, a stopper 222 a is formed at the middle portion in the depth direction of the stopper 2 2 2 and is bent into an L shape toward the inside. Further, a contact portion 2 2 2 b is formed at the top end of the stop portion 222a to project outward. As shown in Figs. 5 and 6A, the stopper 222a is normally locked to the recessed hole 2 3 2b by the elastic force of the stopper 222, which will be described later. On the other hand, when the release member 215 is rotated, as shown in Fig. 6B, the contact portion 22b moves outward to resist the elastic force, so that the locked state of the stop portion 222a can be released. At the rear end of the shelf support 22, hooks 2 2 2 c are formed on the upper and lower portions. The hook 222c is locked to a shelf post (not shown) standing in the display cabinet 1, so that the entire shelf device 2 can be fixed to the display cabinet 1. Specifically, the rack post is formed with a plurality of hook holes (not shown) arranged in the vertical direction, and when the hooks 2 2 2 c are locked to the predetermined hook holes, the rack device 2 can be fixed to the display cabinet 1 at a predetermined height. . The connecting member 23 includes a sliding mechanism 231 extending in the depth direction, and a connecting plate 2 3 2. The sliding mechanism 231 has a fixed plate 231a, a movable plate 231b, and an intermediate plate 2 3 1 c provided between the fixed plate 231a and the movable plate 2 3 1 b. Moreover, the bearing 2 3 1 d is inserted between 11-200302065 between the intermediate plate 2 3 1 c and the fixed plate 2 3 1 a, and the bearing 2 3 1 d is inserted between the intermediate plate 2 3 1 c and the movable plate 2 3 Between 1 b. Thus, the movable plate 231b can slide in the depth direction, as shown by the double arrow in FIG. 4. The front side of the connection plate 2 3 2 is bent into an inverse C-shape, and a recessed hole 2 3 2b is formed in an inner corner portion of the bent portion 232a. The stop 222a is locked to this recessed hole 2 3 2 b and unlocked from this recessed hole 23 2b. Further, a vertically extending locking groove 2 3 2 c is formed near the curved portion 2 3 2 a of the connecting plate 2 3 2 as shown in Figs. 4, 7 A, 7 B, and 7 C. The structure of this lock groove 2 3 2 c will be explained in detail. The lock groove 23 2 c is formed so as to extend downward from the upper end of the connection plate 2 3 2 first, further slightly forward from the lower end, and further downward from the front end. Therefore, even when the lock wire 2 1 4 locked to the lock groove 2 3 2 c is pulled straight up, the lock wire 2 1 4 does not disengage from the lock groove 2 3 2 c, as shown in FIG. 7A. Therefore, when the lock wire 2 i 4 is locked to the lock groove 2 3 2 c, the shelf plate 2 1 can be connected to the connection plate 2 3 2. The fixing plate 2 3 1 a of the sliding mechanism 2 3 1 is fixed to the inner surface of the shelf support 22 with bolts (not shown) or the like, and the connection plate 232 is fixed to the movable plate 2 3 1 b. Thus, the shelf plate 21 is fixed to the shelf support 22 via the connecting member 23, and the shelf plate 21 can be slid in the depth direction by the sliding mechanism 231, as shown in Figs. 7A, 7B, and 7C. Next, the operation of changing the arrangement position of the shelf device 2 will be described mainly with reference to Figs. 7A, 7B and 7C. When the shelf plate 21 is placed on the shelf support 22, as shown in FIG. 7A, the lock wire 2 1 4 is locked to the lock groove 2 3 2c, and as shown in FIG. 6A, the stop 2 2 2 a is locked to the recessed hole 232b. Therefore, the shelf plate 21 is stored on the display case 1 like the shelf plate 21 at the uppermost level shown in FIG. 1. 200302065 When the configuration position of the shelf device 2 is changed, the front claws 2 1 5 c of the member 2 1 5 are first relaxed and held in a state as shown in FIG. 6A. Then, the front claws 2 1 5 c turn inwardly as shown by the dotted arrow symbol in Fig. 6A. Therefore, the claw 21 5d can be moved into contact with the contact portion 2 2 2 b, and the contact portion 222b can be pushed and moved outward to resist the elastic force of the stopper 2 2 2. Therefore, as shown in FIG. 6B, the stop 2 2 2 a is separated from the recessed hole 2 3 2 b, so that the movable plate 2 3 1 b of the sliding mechanism 2 3 1 can move forward. Next, the shelf plate 21 is held by a hand and is pushed forward. Therefore, the connecting plate 2 3 2 connected to the shelf plate 21 can be moved forward, so that the shelf plate 21 is pushed forward, as shown in FIG. 7B (the same as the second shelf device 2 shown at the top of FIG. 1). -kind). Subsequently, the lock line 214 is pulled up along the lock groove 2 3 2c, as shown by a solid line arrow in FIG. 7C. Therefore, the shelf plate 21 can be removed as shown in FIG. 7C. After the shelf board 21 is separated from the connecting member 23, the hooks 22 2c of the shelf support member 22 are hooked to other predetermined hook holes to change the configuration position of the shelf support member 22 to a new position. Subsequently, the lock wires 2 1 4 of the shelf plate 21 are fitted to the lock grooves 2 3 2 c again to connect the shelf plate 2 1 to the connecting member 23. Then, the shelf plate 21 is pushed toward the shelf support member 2 2. Thus, the shelf plate 21 can slide on the shelf support member 2 2. Furthermore, the stopper 222a of the stopper 2 2 2 is locked into the recessed hole 2 3 2 b again, so that the sliding of the slide mechanism 231 in the depth direction can be adjusted. When the above work is completed, the shelf board 21 is supported on the shelf support member 22, and the work of changing the configuration position of the shelf support member 2 2 is completed. According to this embodiment, when the configuration position of the shelf support member 2 2 is changed, the shelf board 21 can be removed from the connecting member 23, so that the installation work of the shelf board and the installation work of the 13-200302065 shelf support member can be separately To perform. Therefore, the work of changing the arrangement position of the rack device can be easily performed, and the positioning of the rack support member can be performed correctly. ㈤A brief description of the diagram.
