M430975 五、新型說明： 【新型所屬之技術領域】 [0001] 本創作係關於可自立之扶手。 [0002] • 【先前技術】 使用日本實用新塑第3034536號專利中記載的起身用辅助 器具，作為老年人或殘障人士從棉被或床上等起身時用 以輔助起身動作之器具。日本實用新型第3034536號專利 中記載的起身用輔助用器具具備：底座係由金屬板等所 構成，二係由底座大致成垂直豎起之支承部，以及二係 插入該二支承部大致成垂直豎起之直線部，係透過接頭 連接到二直線部之橫桿。底座係插入棉被下或床架下。 基本上是在插入棉被下或床架下插入底座。藉此，防止 當起身時起身用輔助器具翻倒。 [0003] • 但是，在實際使用曰本實用新型第3034536號專利中記載 的起身用輔助用器具的情況，會有當起身時該輔助器具 翻倒的可能性。其原因是因底座具有一定程度的重量但 為了要在組裝時容易搬運而設成可搬運程度的重量之故 。底座係藉由鐵板等構成但並未設成可完全防止當起身 時翻倒程度的重量。實際上，市面上所販售的該輔助器 具’在底座為50crax60cm的情況，成為約11kg程度的製 品。如此’習知的起身輔助器具，因底座的重量並不足 夠，所以會有翻倒的危險性。 [0004]單純的思考，加重底座的鐵板部的話’翻倒的可能性可 壓抑在最小限度。但是，底座愈加重愈需要勞力組裝。 另外，鐵板加厚的話，還會有絆倒的危險性。 1012008693-0 10120277#單編號A0101 第3頁/共28頁 M430975 【新型内容】 [0005] 本創作之目的係提供雖然加重底座仍可使組裝容易之自 立型扶手。 [0006] 為了要解決上述課題，本創作具有以下的特徵點〇本創 作是一種可自立之扶手，具備底座及由底座豎起之扶手

考圖面由以下的詳細說明應會更加明白。 【實施方式】 [0018] 以下所述係為本創作之第一實施形態： [0019] 圖1為本創作的第一實施形態的自立型扶手1之透視圖。 圖1中，自立型扶手1具備底座2及扶手部3。扶手部3包括 二支承部31 ;二支柱部38 ;接頭部32、33、34 ;及扶手 桿35、36、37。支承部31可供支柱部38插入。支承部31 為了要以可調整高度的方式固定而以螺紋等（未圖示） 固定支柱部38。扶手桿35插入被分別安裝在該二支柱部 38之二接頭部32，扶手桿35則被安裝在支柱部38。同樣 方式，在二接頭部33之間安裝扶手桿36，在二接頭部34 之間安裝扶手桿37。支承部31藉由底座2所挖開的孔6 ( 圖1中，2個孔為1組），由底座2的背面以螺紋等加以固 定。圖1上，使用左右的橫向排列之2組孔6，使用圖1所 示的扶手桿35、36、37,則即使在面前、正中央或内部 側的任何一處皆可安裝扶手部3。此外，即使安裝該二支 承部31的2組孔6成為斜傾，扶手桿的長度設成與扶手桿 35、36、37不同的長度的話，可將扶手部3安裝在底座2 10120277#單编號 A〇101 第6頁/共28頁 1012008693-0 M43Q975 ο [0020] 圖2為底座2(如圖1所示）分解時之分解透視圖。圖3a為圖 1中的A-A線之剖面圖。圖3b為圖1中的B-B線之剖面圖。 底座2包括第一金屬板21及第二金屬板22。第一金屬板21 由上下利用焊接等接合之2片鐵板所組成。上面的鐵板比 底面的鐵板小。藉此，因端部較低所以可防止絆倒。第 一金屬板21在一端含有用以連結第二金屬板22之第一連 結部23。第一連結部23具有：第一突出部23a，係由第一 g 金屬板21的底面側呈平板狀突出、及第二突出部23b，係 由第一金屬板21的上面侧呈平板狀突出。 [0021] 第二金屬板22包括用以連結第一金屬板21之第二連結部 24。第二金屬板22由上下利用焊接等接合之2片鐵板所組 成。上面的鐵板比底面的鐵板小。藉此，因端部較低所 以可防止絆倒。第二連結部24具有：第三突出部24a，係 由第二金屬板22的底面側呈平板狀.突出、及第四突出部 24b，係由第二金屬板22的上面側呈平板狀突出。 ^ [0022] 在第一突出部23a及第四突出部24b設置複數個用以利用 連結構件5接合之螺紋孔。第二突出部23b及第三突出部 24a設置複數個用以利用連結構件5接合之螺紋孔。第一 突出部23a與第四突出部24b可相對向嵌合。第二突出部 23b與第三突出部24a可相對向嵌合。 [0023] 以橡膠或樹脂等覆蓋底座2的底面或上面較佳（未圖示） 。藉此，不但防止地板受底座2所損傷，也防止手指碰到 底座2的端部而受傷，還可達到止滑效果。 10120277#單編號 A〇101 第 7 頁 / 共 28 頁 1012008693-0 M430975 [0024] 如此，以底座2可分開、連結的方式構成的話，組裝自立 型扶手1時，將底座2分開，第一和第二金屬板21、22各 別搬運，載置在適當的場所，將第一和第二金屬板21、 22連結即可。在單是加重底座的情況，導致要耗費勞力 搬運底座，不過如同本實施形態，以將底座2分開，第一 和第二金屬板21、22各別搬運，將第一和第二金屬板21 、22連結的方式構成的話，即使盡可能加重各個金屬板 仍容易搬運，因而可盡可能加重底座2整體的重量。於是 即使加重底座仍可提供可使組裝容易之自立型的扶手。 [0025] 第一金屬板21與第二金屬板22為相同形狀。即是第一連 結部23與第二連結部24為相同形狀。因此，在製造的階 段，第一和第二金屬板21、22不必區分形狀製造。於是 可削減製造成本。另外，因庫存管理上不必區分第一和 第二金屬板21、22作庫存管理，可削減庫存管理成本。 [0026] 此外，本創作中，並不侷限於第一連結部23與第二連結 部24為相同形狀的情況。也可第一連結部23與第二連結 部24為不同的形狀。 ® [0027] 至於日本專利文獻1中記載之起身輔助器具，在底座為 5Ocmx60cm的情況，成為約11 kg程度的製品。另一方面 ，第1實施形態的底座2為50crax60cm，第一和第二金屬 板21、22使用厚質的鐵板的話，成為約16kg程度的製品 。因此，雖然重量可變重約1. 5倍但仍容易組裝。此外， 上述的重量或尺寸只不過是一個例子而已。 [0028] 以下所述係為本創作之第二實施形態：圖4為本創作的第 二實施形態的自立型扶手所使用的中間金屬板之透視圖 10120277#單编號麵1 帛 8 頁 / 共 28 頁 1012008693-0 M430975 。中間金屬板4連結在第一實施形態之自立型扶手1的第 一金屬板21與第二金屬板22之間。中間金屬板4由上下利 用焊接等接合之2片鐵板所組成。上面的鐵板比底面的鐵 板小。藉此，因端部較低所以可防止绊倒。中間金屬板4 包括可連結至第一連結部23之第三連結部41及可連結至 第二連結部24之第四連結部42。在第三和第四連結部23 、24均設有連結構件5用的螺紋孔。 [0029] 第三連結部41具有：第五突出部41a，係由中間金屬板4 的底面側呈平板狀突出、及第六突出部41b，係由中間金 屬板4的上面側呈平板狀突出。第四連結部42具有：第七 突出部42a，係由中間金屬板4的底面側呈平板狀突出、 及第八突出部42b，係由中間金屬板4的上面側呈平板狀 突出。第一突出部23a與第六突出部41b可相對.向嵌合。 第二突出部23b與第五突出部41a可相對向嵌合。第三突 出部24a與第八突出部42b可相對向嵌合。第四突出部 24b與第七突出部42a可相對向嵌合。 [0030] 如此，藉由利用中間金屬板4可加大底座2。於是可使底 座2容易組裝，且又將底座2更加加重。使用較大的底座2 的話，因可增長扶手部3的扶手桿，所以可提供除起身動 作外還成為步行的輔助之自立型扶手。 [0031] 第三和第四連結部41、42為相同形狀，第一至第四連結 部23、24、41、42為相同形狀。中間金屬板4也可使用2 片以上。因此，也可使用複數個相同的中間金屬板4，反 覆將中間金屬板4彼此間即是第三連結部41與第四連結部 42連結。因使用複數個相同形狀的中間金屬板4，所以不 1〇120277^單編號 A0101 第9頁/共28頁 1012008693-0 M430975 但可削減製造成本及庫存管理成本，還可將底座2加重且 橫向加長。 [0032] 此外，本創作中，並不侷限於第三連結部41與第四連結 部42為相同形狀的情況。也可第三連結部41與第四連結 部42為不同的形狀。 [0033] 以下所述係為本創作之第三實施形態： [0034] 圖5為本創作的第三實施形態的第一和第二金屬板75、76 之局部分解透視圖。在第一金屬板75的連結端設有呈鉤 狀從第一金屬板75突出之突出部71。在第二金屬板76的 .連結端設有可插入突出部71之切槽部72。圖5所示的例子 中，突出部71可由圖5中的箭頭C方向插入切槽部72。 [0035] 惟，依照突出部71和切槽部72的尺寸，也可將突出部71 由圖5中箭頭D的方向，使第一金屬板75—面由上往下轉 動一面插入。 [0036] 藉由滾花加工等，在突出部71的底部設置凹凸部74。藉 由滾花加工等，在切槽部72的底部設置凹凸部73。凹凸 部74及凹凸部73，例如在垂直方向上具有凹凸。藉此可 加強第一和第二金屬板75、76的摩擦以使達到止滑效果 〇 [0037] 圖6為第一和第二金屬板75、76連結時之剖面圖。如圖6 所示，預先在突出部71及切槽部72設置螺紋孔，藉由連 結構件5固定較佳。 [0038] 如同第一實施形態，第一和第二連結部的構造並不侷限 於第三實施形態所示的例子。 1012008693-0 1〇1丽产單编號A〇101 第頁/共28頁 M430975 [0039] 以下所述係為本創作之第四實施形態： [0040] 圖7為第四實施形態的自立型扶手的第一和第二連結部之 剖面圖。第四實施形態中，在第一金屬板83的連結端部 設有由第一金屬板83呈J形狀突出之J形狀突出部81，在 第二金屬板84的連結端部設有可插入J形狀突出部81之具 有J形狀的溝槽之J形狀切槽部82。 [0041] J形狀突出部81和J形狀切槽部82為一直線上形成在第一 和第二金屬板83、84的連結端部。也可從圖5中箭頭C的 方向將J形狀突出部81插入J形狀切槽部82。也可從圖7中 箭頭E的方向一面使第一金屬板83轉動，一面將J形狀突 出部81插入J形狀切槽部82。 [0042] 如第四實施形態所示，第一和第二連結部23、24的構造 並不侷限於第一實施形態所示的例子。 [0043] 以下所述係為本創作之第五實施形態： [0044] 圖8a為第五實施形態的底座之概略分解平面圖。如圖8a 所示，藉由第一金屬板96和第二金屬板97構成底座。在 第一金屬板96的連結端部設有由第一金屬板96的底面側 呈平板狀突出之第一突出部91 (第一連結部）。在第二 金屬板97的連結端部設有由第二金屬板97的上面側呈平 板狀突出之第二突出部92 (第二連結部）。即使藉由如 同圖8a所示的構造，底座仍可分開、連結。惟，因成為 與第一實施形態不同，第一金屬板96與第二金屬板97不 同之構造，所以會有製造成本的增加或庫存管理成本的 增加之可能性。 ΗΠ20277严編號 A0101 第11頁/共28頁 1012008693-0 M430975 [0045] '圖8b為顯示使用圖8a的底座時之中間金屬板95的構造之 圖。中間金屬板95包括可連結至第一突出部91之第三連

New description: [New technical field] [0001] This creation is about self-supporting handrails. [0002] [Prior Art] An auxiliary device for getting up as described in Japanese Utility Model No. 3034536 is used as an apparatus for assisting an uplifting operation when an elderly person or a person with a disability gets up from a quilt or a bed. The auxiliary device for lifting body described in Japanese Patent Application No. 3034536 includes a base made of a metal plate or the like, a second support portion that is vertically erected by the base, and a second system inserted into the two support portions to be substantially vertical. The straight portion that is erected is connected to the crossbar of the two straight portions through the joint. The base is inserted under the quilt or under the bed frame. Basically, insert the base under the quilt or under the bed frame. Thereby, it is prevented to get up and fall over with the aid when getting up. [0003] However, in the case of actually using the auxiliary device for getting up as described in Japanese Patent No. 3034536, there is a possibility that the assisting device may fall over when getting up. The reason for this is that the base has a certain degree of weight, but is designed to be transportable to the extent that it can be easily transported during assembly. The base is constructed of an iron plate or the like but is not provided to completely prevent the weight from falling over when getting up. In fact, the auxiliary device sold on the market has a degree of about 11 kg when the base is 50crax 60 cm. Such a conventional lifting aid has a risk that the weight of the base is insufficient, so there is a risk of falling over. [0004] Simple thinking, if the iron plate portion of the base is added, the possibility of falling over can be suppressed to a minimum. However, the heavier the base needs to be assembled by labor. In addition, if the iron plate is thickened, there is a danger of tripping. 1012008693-0 10120277#单号A0101 Page 3 of 28 M430975 [New Content] [0005] The purpose of this creation is to provide a self-supporting handrail that can be easily assembled even though the base is heavy. [0006] In order to solve the above problems, the present invention has the following features. The present invention is a self-supporting armrest having a base and an armrest portion erected from the base. The base includes first and second metal plates that are separable from left to right. The first metal plate includes a first joint for joining the second metal plate, and the second metal plate includes a second joint for joining the first metal plate. Preferably, the first connecting portion and the second connecting portion have the same shape, and the first connecting portion and the second connecting portion may be fitted to each other so as to face each other. [0008] Preferably, the first connecting portion has a first protruding portion that protrudes in a flat shape from a bottom surface side of the first metal plate, and a second protruding portion that protrudes from the upper surface side of the first metal plate. . The second joint portion has a third projecting portion which protrudes in a flat shape from the bottom surface side of the second metal plate and a fourth projecting portion which protrudes in a flat shape from the upper surface side of the second metal plate. The first protruding portion and the fourth protruding portion may be fitted to each other. The second protrusion and the third protrusion may be fitted to each other. Preferably, the intermediate metal plate further includes a third connecting portion connectable to the first connecting portion and a fourth connecting portion connectable to the second connecting portion. The first to fourth joint portions have the same shape. [0010] Preferably, the intermediate metal plate further includes a third connecting portion connectable to the first connecting portion and a fourth connecting portion connectable to the second connecting portion. The third connecting portion has a fifth protruding portion which is formed in a flat shape from the bottom surface side of the intermediate metal plate, and a sixth protruding portion which is formed by the upper surface of the intermediate metal plate 10120277: ^ single number A 〇 101 page 4 / A total of 28 pages 1012008693-0 M430975 side is flat protruding. The fourth joint portion has a seventh projecting portion which protrudes in a flat shape from the bottom surface side of the inter-metal plate, and an eighth projecting portion which protrudes in a flat shape from the upper surface side of the intermediate metal plate. The first protrusion and the sixth protrusion may be fitted to each other. The second protrusion and the fifth protrusion can be opposite each other. The third protruding portion and the eighth protruding portion are relatively rigid. The fourth protrusion and the seventh protrusion are oppositely fitted. Preferably, the intermediate metal plate further includes a third connecting portion that is far from the first connecting portion and a fourth connecting portion that is connectable to the second connecting portion. [0012] Preferably, the first joint portion includes a first projecting portion which is formed in a flat shape by the bottom surface side of the first metal plate. The second joint portion includes a second projecting portion that protrudes in a flat shape from the upper side of the second metal plate. [0013] Preferably, the first connecting portion is a protruding portion that protrudes from the first metal plate. The second joint portion is a slit portion into which the projection portion can be inserted. [0014] Preferably, the first joint portion is a J-shaped projecting portion in which the first metal plate protrudes in a J shape. The second joint portion is a J-shaped slit portion of the J-shaped groove into which the J-shaped projecting portion can be inserted. _] By separating and joining the bases, the separated metal plates can be transported to the assembly position to be coupled. Therefore, it is possible to provide a self-supporting handrail that can be easily assembled although the weighted base can be assembled. A base which can be separated or connectable by a simple configuration using the first to fourth projections is provided. Further, when the first and second connecting portions are formed in the same shape, the first and second metal plates can be formed into the same shape, so that the manufacturing cost and inventory management cost of the base can be reduced. [_Although it is easier to use a detachable and connectable intermediate metal plate. 10120277^^^ A〇101 帛 5 pages / Total 28 pages 1012008693-0 M430975 Mounting base, but still can be aggravated and lengthened. In addition to getting up, it can also be used as a walking armrest. An intermediate metal plate which can be separated and joined by a simple configuration of the fifth to eighth projections can be provided. Further, when the first to fourth connecting portions are formed in the same shape, not only the first and second metal plates are formed in the same shape, but also the intermediate metal plates are formed in the same shape, so that the manufacturing cost and inventory management cost of the base can be reduced. . [0017] The above and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description. [Embodiment] The following is a first embodiment of the present invention: [0019] Fig. 1 is a perspective view of a self-erecting handrail 1 according to a first embodiment of the present invention. In FIG. 1, the self-standing armrest 1 is provided with the base 2 and the armrest part 3. The armrest portion 3 includes two support portions 31; two post portions 38; joint portions 32, 33, 34; and armrest bars 35, 36, 37. The support portion 31 is insertable into the pillar portion 38. The support portion 31 fixes the pillar portion 38 with a screw or the like (not shown) in order to be fixed in a height-adjustable manner. The grab bars 35 are inserted into the joint portions 32 of the two-pillar portions 38, respectively, and the grab bars 35 are attached to the pillar portions 38. In the same manner, the handrail lever 36 is attached between the two joint portions 33, and the handrail lever 37 is attached between the two joint portions 34. The support portion 31 is fixed by a hole 6 (one of the two holes in Fig. 1) by the base 2, and is fixed by a screw or the like from the back surface of the base 2. In Fig. 1, using the two sets of holes 6 arranged side by side in the lateral direction, and using the handrail bars 35, 36, 37 shown in Fig. 1, the armrest portion 3 can be attached at any position on the front, the center or the inner side. Further, even if the two sets of the holes 6 in which the two support portions 31 are mounted are inclined, and the length of the handrail bar is set to be different from the length of the handrail levers 35, 36, 37, the armrest portion 3 can be attached to the base 2 10120277# No. A 〇 101 Page 6 of 28 1012008693-0 M43Q975 ο [0020] FIG. 2 is an exploded perspective view of the base 2 (shown in FIG. 1). Figure 3a is a cross-sectional view taken along line A-A of Figure 1. Figure 3b is a cross-sectional view taken along line B-B of Figure 1. The base 2 includes a first metal plate 21 and a second metal plate 22. The first metal plate 21 is composed of two iron plates joined by welding or the like. The upper iron plate is smaller than the bottom iron plate. Thereby, it is possible to prevent tripping due to the lower end portion. The first metal plate 21 has a first joint portion 23 for joining the second metal plate 22 at one end. The first connecting portion 23 has a first protruding portion 23a that protrudes in a flat shape from the bottom surface side of the first g-metal plate 21 and a second protruding portion 23b that protrudes from the upper surface side of the first metal plate 21 . [0021] The second metal plate 22 includes a second joint portion 24 for joining the first metal plates 21. The second metal plate 22 is composed of two iron plates joined by welding or the like. The upper iron plate is smaller than the bottom iron plate. Thereby, it is possible to prevent tripping due to the lower end. The second connecting portion 24 has a third protruding portion 24a which is formed in a flat shape on the bottom surface side of the second metal plate 22, and a fourth protruding portion 24b which is protruded from the upper surface side of the second metal plate 22 . [0022] A plurality of screw holes for engaging by the joint member 5 are provided in the first projecting portion 23a and the fourth projecting portion 24b. The second projecting portion 23b and the third projecting portion 24a are provided with a plurality of screw holes for joining by the joint member 5. The first projecting portion 23a and the fourth projecting portion 24b are fitted to each other. The second projecting portion 23b and the third projecting portion 24a can be fitted to each other. [0023] It is preferable to cover the bottom surface or the upper surface of the base 2 with rubber or resin or the like (not shown). Thereby, not only the floor is prevented from being damaged by the base 2, but also the finger is prevented from hitting the end of the base 2 and being injured, and the anti-slip effect can be achieved. 10120277#单号A〇101 Page 7 of 281012008693-0 M430975 [0024] Thus, when the base 2 can be separated and connected, when the self-supporting handrail 1 is assembled, the base 2 is separated, the first and the first The second metal plates 21 and 22 are separately transported and placed on an appropriate place, and the first and second metal plates 21 and 22 may be coupled. In the case where the base is merely weighted, it takes labor to carry the base, but as in the present embodiment, the base 2 is separated, and the first and second metal plates 21, 22 are separately transported, and the first and second metal plates 21 are respectively In the case of the 22-connection method, the weight of the entire base 2 can be increased as much as possible even if the metal plates are easily handled as much as possible. Thus, even if the base is weighted, a self-supporting armrest that can be easily assembled can be provided. [0025] The first metal plate 21 and the second metal plate 22 have the same shape. That is, the first connecting portion 23 and the second connecting portion 24 have the same shape. Therefore, at the stage of manufacture, the first and second metal plates 21, 22 do not have to be shaped differently. This can reduce manufacturing costs. In addition, inventory management can be reduced by eliminating the need to distinguish between the first and second metal plates 21 and 22 for inventory management. Further, in the present creation, the first joint portion 23 and the second joint portion 24 are not limited to the same shape. The first connecting portion 23 and the second connecting portion 24 may have different shapes. In the case of the body-assisted device described in Japanese Patent Laid-Open No. Hei., the product is about 11 kg when the base is 50 cm x 60 cm. On the other hand, the base 2 of the first embodiment is 50 crax 60 cm, and when the first and second metal plates 21 and 22 are made of a thick iron plate, the product is about 16 kg. Therefore, although the weight is about 1.5 times, it is still easy to assemble. Moreover, the above weight or size is merely an example. [0028] The following is a second embodiment of the present invention: FIG. 4 is a perspective view of an intermediate metal plate used in the self-supporting handrail of the second embodiment of the present invention, 10120277# single-numbered surface 1 帛 8 pages / Total 28 pages 1012008693-0 M430975. The intermediate metal plate 4 is coupled between the first metal plate 21 and the second metal plate 22 of the self-supporting handrail 1 of the first embodiment. The intermediate metal plate 4 is composed of two iron plates joined by welding or the like. The upper iron plate is smaller than the bottom iron plate. Thereby, it is possible to prevent tripping due to the lower end portion. The intermediate metal plate 4 includes a third connecting portion 41 connectable to the first connecting portion 23 and a fourth connecting portion 42 connectable to the second connecting portion 24. A screw hole for the coupling member 5 is provided in each of the third and fourth coupling portions 23 and 24. The third connecting portion 41 has a fifth protruding portion 41a that protrudes in a flat shape from the bottom surface side of the intermediate metal plate 4 and a sixth protruding portion 41b that protrudes from the upper surface side of the intermediate metal plate 4 in a flat shape. . The fourth connecting portion 42 has a seventh projecting portion 42a which protrudes in a flat shape from the bottom surface side of the intermediate metal plate 4 and an eighth projecting portion 42b which protrudes in a flat shape from the upper surface side of the intermediate metal plate 4. The first protruding portion 23a and the sixth protruding portion 41b are engageable in opposite directions. The second protruding portion 23b and the fifth protruding portion 41a are relatively slidably fitted. The third protruding portion 24a and the eighth protruding portion 42b are fitted to each other. The fourth projecting portion 24b and the seventh projecting portion 42a are fitted to each other. [0030] Thus, the base 2 can be enlarged by using the intermediate metal plate 4. Thus, the base 2 can be easily assembled and the base 2 can be further weighted. When the larger base 2 is used, since the handrail lever of the armrest portion 3 can be enlarged, it is possible to provide a self-supporting handrail which is an auxiliary for walking in addition to the body movement. [0031] The third and fourth joint portions 41, 42 have the same shape, and the first to fourth joint portions 23, 24, 41, 42 have the same shape. It is also possible to use two or more sheets of the intermediate metal plate 4. Therefore, a plurality of identical intermediate metal plates 4 may be used, and the intermediate metal plates 4 may be connected to each other, that is, the third connecting portion 41 and the fourth connecting portion 42. Since a plurality of intermediate metal plates 4 of the same shape are used, the number of the intermediate metal plates 4 of the same shape is not 1, 120,277, the single number A0101, the 9th page, the total of 28 pages, the 1012008693-0, the M430975, but the manufacturing cost and the inventory management cost can be reduced, and the base 2 can be weighted and laterally Lengthen up. Further, in the present creation, the third joint portion 41 and the fourth joint portion 42 are not limited to the same shape. The third connecting portion 41 and the fourth connecting portion 42 may have different shapes. [0033] The following is a third embodiment of the present invention: [0034] FIG. 5 is a partially exploded perspective view of the first and second metal plates 75, 76 of the third embodiment of the present invention. A protruding portion 71 projecting from the first metal plate 75 in a hook shape is provided at the joint end of the first metal plate 75. At the joint end of the second metal plate 76, a slit portion 72 into which the projection 71 can be inserted is provided. In the example shown in Fig. 5, the protruding portion 71 can be inserted into the slit portion 72 by the arrow C direction in Fig. 5 . [0035] However, depending on the size of the protruding portion 71 and the slit portion 72, the protruding portion 71 may be inserted from the top to the bottom of the first metal plate 75 by the direction of the arrow D in Fig. 5 . [0036] The uneven portion 74 is provided at the bottom of the protruding portion 71 by knurling or the like. The uneven portion 73 is provided at the bottom of the grooving portion 72 by knurling or the like. The uneven portion 74 and the uneven portion 73 have irregularities in the vertical direction, for example. Thereby, the friction of the first and second metal plates 75, 76 can be enhanced to achieve the anti-slip effect. [0037] Fig. 6 is a cross-sectional view showing the first and second metal plates 75, 76 joined. As shown in Fig. 6, a threaded hole is provided in the protruding portion 71 and the grooved portion 72 in advance, and is preferably fixed by the connecting member 5. [0038] As in the first embodiment, the configuration of the first and second connecting portions is not limited to the example shown in the third embodiment. 1012008693-0 1〇1丽产单号 A〇101 Page/Total 28 pages M430975 [0039] The following is a fourth embodiment of the present invention: [0040] FIG. 7 is a self-standing type of the fourth embodiment A cross-sectional view of the first and second joints of the armrest. In the fourth embodiment, the J-shaped projecting portion 81 projecting in the J shape from the first metal plate 83 is provided at the connecting end portion of the first metal plate 83, and the J-shaped protruding portion 81 is provided at the connecting end portion of the second metal plate 84. The shape-protruding portion 81 has a J-shaped groove portion 82 having a J-shaped groove. The J-shaped protruding portion 81 and the J-shaped slit portion 82 are formed at a connecting end portion of the first and second metal plates 83 and 84 in a straight line. The J-shaped projection 81 can also be inserted into the J-shaped notch portion 82 from the direction of the arrow C in Fig. 5 . The J-shaped projection 81 may be inserted into the J-shaped notch portion 82 while the first metal plate 83 is rotated in the direction of the arrow E in Fig. 7 . As shown in the fourth embodiment, the structures of the first and second connecting portions 23 and 24 are not limited to the examples shown in the first embodiment. [0044] The following is a fifth embodiment of the present invention: [0044] Fig. 8a is a schematic exploded plan view of the base of the fifth embodiment. As shown in Fig. 8a, the base is constituted by the first metal plate 96 and the second metal plate 97. A first protruding portion 91 (first connecting portion) projecting in a flat shape from the bottom surface side of the first metal plate 96 is provided at a connecting end portion of the first metal plate 96. A second projecting portion 92 (second joint portion) projecting in a flat shape from the upper surface side of the second metal plate 97 is provided at a connecting end portion of the second metal plate 97. Even by the configuration as shown in Fig. 8a, the base can be separated and joined. However, since the first metal plate 96 and the second metal plate 97 are different from each other in the first embodiment, there is a possibility that the manufacturing cost increases or the inventory management cost increases. ΗΠ20277 Strictly numbered A0101 Page 11 of 28 1012008693-0 M430975 [0045] Fig. 8b is a view showing the configuration of the intermediate metal plate 95 when the base of Fig. 8a is used. The intermediate metal plate 95 includes a third connecting portion 93 connectable to the first protruding portion 91 and a fourth connecting portion 94 connectable to the second protruding portion 92. The third joint portion 93 has the same shape as the second projecting portion 92. The fourth joint portion 94 has the same shape as the first projecting portion 92. The intermediate metal plate 95 as shown in Fig. 8b can also be used. By using two or more intermediate metal plates 95, the base can be weighted and laterally elongated. The intermediate metal plate 95 can be formed into one shape, so that the manufacturing cost and inventory management cost of the intermediate metal plate 95 can be reduced. [0046] The fifth embodiment is a simple configuration. Therefore, it is expected to reduce the manufacturing cost. [0047] Further, in the fifth embodiment, the first metal plate 96, the second metal plate 97, and the intermediate metal plate 95 are both welded by the upper and lower iron plates, and the upper iron plate can be reduced to make it difficult to trip. . [0048] FIG. 9 is a schematic plan view showing a case where the armrest portions are formed in an L shape by using three support portions 31 in the self-supporting handrail of the first embodiment. When the L-shaped joint is used, the armrest portion may be formed in an L shape. [0049] The above description has been described in detail, but all the points in the foregoing description are merely examples of the present invention and are limited to the scope. Of course, various modifications or variations can be made without departing from the scope of the present invention.
