Description

M244005 V. Creation Instructions (l)

、 It is mainly aimed at the connection between the front and rear leg sections that can be folded up and the upper leg section of the rear leg support to support fast and convenient design when the connecting rod section of the paragraph is live. I. [Technical field to which the new type belongs] This creation is The utility model provides a round chair structure. The round chair frame is pivoted and combined with the transfer section. The round chair frame can be combined with the respective screw locks on the chair frame by being placed in the front to facilitate the folding of the round chair. By. 2. [Previous Technology] The industry has developed a set of seat chairs and tools with different forms of use, which can be easily folded and made appropriate choices. Here, the patent was published on January 1, 2011. The new case (see Attachment I) 1, 2 The preset height is supported by the support shaft 2 and two front foot bars 12 are opened upward to the two extension support mechanisms. 3 and two forefoot pieces 3 2, 3 3 to serve as each other's mechanism 3 The extension rod 3 1 The tip and the corresponding section 4 are erected downward to pivotally integrate each other into the periphery to form a foldable Form III. [Content] Chairs with a diameter can be distinguished from lightweight chairs that cannot be folded or folded, but can be folded and retracted. The chair can be used for personal application and will be announced by a related industry. No. [Folding, the folding chair is made by front and rear tripods 3 to pivot the two components into one body, each correspondingly assembled to extend the supporting mechanism 3, 1 2 The parent part is stretched and folded by two adjustment springs, After being extended by two extensions, two rear foot rods 22, and a seat frame 1 in order, and a pivot 4 3, a seat cushion 5 is combined with the seat frame 4 state.

This creation is based on revealing the folding chair erection form of the same nature.

Page 5 M244005 V. Creation Instructions (2) Another new form or stretcher is used to steadily lay the original creation. The legrest is facing up, the tube is the chair frame, the frame is facing upward, and the two joints are folded. After that, the front foot presses the chair frame four, [the front and rear leg parts 5 that implement this creation, and the front and rear 15 are connected and pivoted 11]. A snap cap 12 can be allowed to protrude at one end. The transfer of the joints is based on the linking of the legs of the connecting rods and the legs of the chair to the upper part of the chair. The two sides of the two legs are integrated into one. The elastic top buckle 丄 3 pieces 14 inserted into the upper pipe section of the front foot 1 correspondingly penetrates through it, and the upper pipe section is tightly sleeved and is composed of a support member of a round chair, which can be set and can be implemented with simple operation. The main purpose is to provide the connection support part of the pipe section with the movable wall of the chair frame to receive the fitting support section of the pipe section, and then pivotally connect it in an azimuth; according to this, the group first protrudes from the front leg and faces the upper fastener. Press in to make the front stand stand up and follow the connection support section to make the front and rear stand reach the way] Regardless of the round chair structure, refer to No. 1, 2, Chair frame 3, Rod section 6, Second connection Part 7 tripods 1, 2 in the second component period. Individuals do not use folding to achieve fast closing and convenient pivoting before and after being locked by separate screws to connect with the first supporting member of the front leg section. The support department stretched the boundaries in the meantime and moved it to the next level. ′ It is mainly composed of undertaking pipe section 4 and connection support. In the preset transfer section, the borrowing chair frame 3 is pre-assembled around the front and rear legs 丄, 2 sections of the downwardly facing pipe wall are provided with holes 3 1 to allow the internally threaded holes 4 i to receive the pipe section 4 for urgent rotation Into it.

M244005 V. Creation instructions (3) Lifting the connecting rod section 6 'One end of the rod 6 1 is the receiving pipe section 4 center threaded hole 4 1 which can be correspondingly screwed into the chair wall C f 3, and the other end forms a A section 6 2 is provided with a hole 6 3 between sections f. Supporting section 5, a pipe section 51 at one end can be fitted with a front leg, and the outer wall of section I in the upper part of the pipe section 1 has a hole 5 2 on one side of the wall section, and j slave 5 1 extends toward the outer pipe wall at a distance of two. The lug 5 3 is allowed to be inserted into the rod section 6-the end buckling section 6 2 sets, and the deduction pin 2 ... 3 during the hole 531 and the buckling section 62 hole 63 sequence shell second connection section 7 ( (See detailed drawings in the first and third figures E), the distance from the two lugs 7.1 to allow the connecting rod segment 6-end buckle part core pin "to sequentially penetrate the hole segment G between the two lugs 71 is: G Hole 63, the fork is pinched by the other end of the second connecting portion 7 ^ 4 is for tightly fitting the rear leg 2 to the upper pipe for positioning. Only the pin 7 5 is used to assemble the second structure (see the second and third figures) The end of the screw 61 is correspondingly locked into the hole 41 of the chair frame section 6, and the threaded part 5 of the official section 4 is received from the front foot 丄 upward 2, and the pipe section j of the joint support section 5 is sleeved for connection. Supports top buckle 1 3 and its fasteners 1 4 can be used as an outward protruding band = hole eight 5 2 moved to the elastic holding part 5 protruding toward the outer tube wall two lugs 5 ^ ^ azimuth limit, 6 2 sets of joint support parts Insertion and debit 5 4 will _ 2 fit the connecting rod segment 6 Buckle the second picture B detailed picture, the third picture!) Details the components and azimuth combination (for example, the second connection part 7 is forcedly inserted, and the rear leg 2 is upwardly detailed pipe section), and the borrowing pin 7 5 the second structure containment section 7 4 (as shown in the third picture, plus the position limit, in the second title

1 2 J V. Creation instructions (4) Two lugs 7 i extending upward from the connecting portion 7 and the corresponding connecting rod section 6 and its fastening portion 6 2 sets of fan locks are pivoted on the chair frame 3 Integrated (such as the second figure C and the detailed figure f), and the deduction pin 73 will be the two forms of the round chair group body 8. (Figure 4), is to fold the elastic fasteners 2 and implement AV 2 before pressing out (such as the steps, "two different tripods 1 can be detached from the orientation to support the boundary, then ^ 1 means It can follow the connection support section 5 and its pipe section 51 to carry out activities = shift (as in step B), and then press down the chair frame 3 in a way that enables the front and back feet >, 1, 2 to achieve a convenient folding form ( See step ◦).
