Description of the new type: [Technical field to which the new type belongs] This new type is a folding chair that can be used when unfolded and can be flattened after being folded to reduce the storage and carrying volume. [Prior art] There are many types and types of folding chairs in known techniques. Among them, the patent case No. 471284 (that is, US No. 6332646 m),
提供一種可以攤平而方便收藏的折合椅，此種折合椅在展 開供乘坐時也很舒適。雖然如此，前述新型專利案在收藏 時，使用者需要同時按壓兩側延撐機構的調整彈片，才沪 讓被該等延撐機構斜撐的坐框攤平，在收藏的操作上略為 不便，而在展開的位置時，若他人刻意按㈣機構的調 整彈片，會使得原本呈前低後高的坐框瞬間躺平，並且引 起不當的收合，在安全性的設計上較不理想。 【新型内容】 ^ 本新型之目的係在提供一種結構創新，且在展開使用 時具有較佳安全性之折合椅。 、本新型之折合椅包含：一腳架單元、—與該腳架單元 以可樞毹方式連結並往後上方斜伸的延撐單元，以及一以 前低後高的方式架設在該腳架之一前腳框及 延撐框間的坐框單元，上述架 可枢擺方式交又連接的後腳框。^括—與前腳框以 本新型的特徵在於：該延擇單元更包括兩個左右間厂 地固定在延撐框上的跨#板，每個料板皆具有—供^ 5 • M275769 :=行:腳桿中的其中之一靠抵的跨靠部，又該折合 ♦可更包广可滑移地穿套在該等前腳桿中的盆中之 = :Γ’上述安全扣合機構包括—當折合椅位在展 開位置時插固在該跨靠板上 框的抵靠以及安全扣合機構之扣a广跨罪板與前腳 時具有較佳的安全性構之扣S，可㈣折合椅在展開 【實施方式】 容、特點與功效，在 細說明中，將可清楚A folding chair that can be flattened and conveniently stored is provided, and this folding chair is also comfortable when it is unfolded for riding. Nevertheless, during the storage of the aforementioned new patents, the user needs to simultaneously press the adjusting springs of the extension support mechanisms on both sides in order to flatten the seat frame diagonally supported by the extension support mechanisms, which is slightly inconvenient in the operation of storage. In the unfolded position, if someone deliberately presses the adjusting spring of the cymbal mechanism, the seat frame that was originally low in front and high in the back will lie down instantly and cause improper folding, which is not ideal in terms of safety design. [New content] ^ The purpose of this new model is to provide a folding chair with innovative structure and better safety when deployed. The folding chair of the new model includes: a tripod unit, an extension support unit which is pivotably connected to the tripod unit and extends obliquely upwards and backwards, and is mounted on the tripod in a manner of low front and high rear. A seat frame unit between the front foot frame and the extension support frame, and the above frame can be pivoted and connected to the rear foot frame. ^ Included—The feature of this model with the front foot frame is that the extension unit further includes two span # plates fixed on the extension frame on the left and right, each material plate has—for ^ 5 • M275769: = Row: One of the footrests against which the abutment rests, and it should be folded. ♦ It can be worn more widely and slidably in the basins of these forefoot rods =: Γ 'The above-mentioned safety fastening mechanism includes — When the folding chair is in the unfolded position, the abutment of the frame and the buckle of the safety buckle mechanism are fastened to the buckle S. The buckle S has a better safety structure when it crosses the front board and the front foot. The chair is unfolding [Implementation] The contents, characteristics and effects will be clear in the detailed description.

The fixed portion 221 and a straddle portion 222 extending to the forefoot bar ill on the same side have a strut groove 223 on the straddle portion 222 that faces backwards and fits with the front foot rod 1U. The aforementioned second rafter passes through the same extension rod 211 and the front foot rod Hi from 23 pieces. The position of this second trailing rod 3 is close to the other foot rod! i i is at the top and is positioned above the abutment plate 22. The cat-shaped seat frame unit 3 is a sloping frame above the extension unit 2 and the tripod unit, and includes: a ring-shaped seat frame 31, four pivot joints 32 fixed to the seat frame 31, and four first Three pivots 33, and a ㈣34 frame on the seat frame 3 'These pivot joints 32 are respectively corresponding to the extension pole 2m and the top edge of the rear foot lever' Each pivot joint 32 has two left and right intervals Pivot pieces 321 are erected beside the corresponding extension rods 211 and the rear foot rod 121, and the first pivot shafts 33 疋 pass through the corresponding extension rods 2η and the perch moon 321 or the rear foot rod 121 and the pivot respectively. The connecting piece 32 allows the seat frame M to be installed in a swingable manner above the extension frame 21 and the rear foot frame 12. The safety locking mechanism 4 of the new model is movably put on one of the forefoot rods U1, the slide sleeve 41 of the dagger and a dental mouthpiece on the forefoot rod, and the extension support Rod 2 n 42, plug holders extending in the direction of the stem 211 ... The plug holder 42 has two plug bars 421 spaced back and forth, and plugs between the plug bars 421 and having a width approximately equivalent to that of the abutting plate 22固 -M275769 Slot 422. When the folding chair of this new model is in the unfolded position shown in Figure 2 and Figure 2, the chatter rod m is leaning against the back of the slot #slotted milk across the board 22 before tilting to Portugal. The material insertion rods 421 of the closing mechanism 4 are respectively inserted in front and rear of the cross plate 22, that is, the cross plate 22 is placed in the insertion groove 422 of the safety fastening mechanism 4. The front foot frame u cannot be pivoted backwards or forwards with the second trailing shaft 23 as a fulcrum, so the entire folding chair has better safety when deployed. 〃 4 Please refer to Figures 4, 5, and 6, when the new folding chair is required When folding, first push up the safety fastening mechanism 4 so that the plunger 421 is completely separated from the cross plate 2 and then press down the rear of the seat frame 31, That is, the front end of the seat frame 31 that is set across the board 22 is moved upward with the second pivot axis 23 as a fulcrum, and the bottom end of the front foot frame U is swung backward with the first pivot axis 13 as a fulcrum. The width of the frame U, the rear foot frame 12, and the extension frame 21 are different. Therefore, after folding, the foot frames U, 12 and the extension frame 21 overlap inside and outside, and the front and rear foot frames H, 21 are front and rear. The connecting rods 112 and 122 face back in parallel, and the extension connecting rod 212 of the extension frame U is located in the front. When the circular sitting frame 31 is straddled over the lame frames U, 12 and the lame frame 21, the whole is folded. The chair will be in a closed position. When the folding chair with the same reason i is unfolded, as long as the front foot frame 2M end faces forward and the rear foot frame 12 crosses, and then the bottom end of the extension frame M faces ^ = 于 延«21 When the front-end straddle plate 22 is in conflict with the foot cup 111 on the same side of the front foot frame u, the deployment angle of the entire folding chair is fixed. In order to improve the safety of the folding chair when it is deployed, the safety fastening mechanism 4 times -M275769 push, so that the transgression board 22 is set up in the insertion groove 422 of the insertion seat 42, which can improve the safety of the folding chair when it is deployed. More specifically and t, the new type utilizes the contact between the two supporting plates 22 and the front foot bar lu, and has actually reached the position of the folding chair, and the design of the safety buckle mechanism 4 can avoid external force & folding chair Improper collapsing, so the design of the folding chair of the new model not only has a novel xe design, but also has the effect of improving the safety of use. ^ However, the above is only the preferred embodiment of the new model.
