Description

M245872, creation description α) [Technical field to which the new type belongs] == Related—A chair with a linked cushion and a seat, especially a chair with a linked cushion and a seat, which is connected to the ^ back pivot through a -link Between the rear edge of the seat and the rear edge of the seat, the angle of change can be reached at the same time as the month and the seat, and the simplified point pivoting reduces the production cost. [Previous technology] μ "Hi structure is as shown in Figures 10-13 As shown (that is, Taiwan Patent Bulletin No. f 549043, but its component names and numbers are mainly based on this article), mainly including: Wen Yue il movable rod 6 1 and a rear movable rod 6 2 are simultaneously a base 6 0, Connected to the base 60, an upper f chair 70, pivotally connected to the front movable rod 61, and a lower second arm pivoted to the rear movable rod 62, and the seat of the backrest 80 The rear end of the chair 70 is a pivotable pivot joint; a linking part 90 is composed of one or two and a slider 92 connected to the bottom surface of the seat 70, and the slider 92 is formed by a rear through hole. 921 and a front pass 922 allow the outer edge surface of the L-shaped Caihan 91 to pass through, and use the outer edge surface of the L-shaped rod 91 to lock the 9 2 3 ^ The limit of the moon block 92 on the outer edge of the L-shaped rod 91 is such a conventional structure. The disadvantages of the conventional structure are as follows: [1] The seat and the back are not connected to you and you, ^ Tian & Shide Ershan moves' reduces the comfortable sound of riding. It is customary to use a structure, even if the back is pressed against I degree ^ h, the crime is only at most on the sin month.

M245872 IV. Creation instructions (2) 'Monthly sloping staff members' but the seat is not adjusted before it' will not produce any $ degree change. In this way, in terms of ergonomics, the lying position will be greatly reduced. Comfort, and even if the reclining angle of the seat is adjusted separately, it is not possible to quickly grasp the comfortable angle that can be achieved by the simultaneous movement of the chair and the back. This part is one of the disadvantages of the conventional structure. [2] The design between the slider and the [rod] is poor, which is not conducive to joint movement. As far as the conventional structure is concerned, the slider 9 2 moves on the outer edge surface of the L-shaped rod 9 1, which is a necessary condition for changing the angle between the conventional seat Ke 70 and the sin back 80, and the slider g 2 is hollow. Then the L-shaped rod 9 1 needs to pass through at least the rear and front through holes 921 and 9 22 of the slider 9 2 at the same time to be movable, that is, as long as the rear and front through holes 921 and 9 2 2 are formed, Slightly deflected, but not actually located on the same axis X 1 of the slider 9 2 (refer to Figure 13 for cooperation), that is, it is not conducive to the movement of the L-shaped rod 9 1 ', and if the slider 9 2 For a solid design, the movement of the L-shaped rod 91 will be more difficult. Especially used in the design of the cooperation of the slider 92 and the L-shaped rod 91, there are still two sets of such designs, as long as the movement path X2 of the seat 70 is slightly deflected to either side without being parallel to the axis χ 丨, The probability that the conventional structure will not move smoothly will greatly increase. [3] The joints are complex, inconvenient to assemble and costly. In order to change the angle of the seat and the backrest, it is necessary to simultaneously link the complex joint elements such as the front movable lever, the rear movable lever, the seat, the backrest, the L-shaped lever, and the slider. 2 If the sliding of any group of sliders on the L-shaped rod is not smooth, the seat and #months cannot be linked at all, which is a drawback of practice. Such a complicated link design is also a disadvantage of inconvenient assembly and increased cost. . M245872 4. Creation instructions (3) Therefore, it is extremely necessary to design a chair with a linked cushion and a seat, which are more ideal in function and structure, to solve the shortcomings of conventional devices. [New content] The main purpose of this creation is to provide a chair with a linked cushion and a seat, which synchronizes the seat and the back to achieve a comfortable ergonomic seating experience. A secondary objective of this creation is to provide a chair with a linking cushion and a seat. The seat and the backrest are simultaneously linked with a point pivot by a simplified single link to achieve simultaneous changes in the seat with a streamlined structure. Benefits with backrest. Another object of the present invention is to provide a chair with a linkage cushion and a seat, which has a compact linkage joint, rapid movement, easy assembly and low cost. The technical solution adopted by this creative solution to the lack of conventional devices is as follows: A chair with a linked cushion and a seat includes a base, a seat, a back, and a link, wherein: the base is provided with A front end and a rear end; the seat is provided with a front edge portion and a rear edge portion, and the seat can be pivoted on the base by the left and right sides of the front edge portion; The backrest has a front surface and a pivot joint. The backrest can be pivoted on both sides of the pivot joint and rotates on the base. The backrest is formed between the front of the backrest and a vertical line at the rear end of the base. A seated angle; the linkage is pivotally connected to the seat and the back with one end and a sliding slot respectively;

Page 7 M245872 IV. Creation Instructions (4) By this, when the vertical angle between the front of the backrest and the back of the base is enlarged from the angle of the sitting position to the angle of the lying position, the seat is synchronized with the seat. The other end of the base is the car swinging from the heart. The above-mentioned objects and advantages of this creation can be easily understood from the detailed description and accompanying drawings of the selected embodiments below. The following examples and drawings are used to explain this creation in detail. [Embodiment]

The rear edge portion 22 of 20 is the bottom surface, and the sliding portion 4 丨 allows the connecting portion 3 of the backrest 30 to be slidably pivoted. This is the creation of a chair with linked cushions and seats. The principle of the movement of this creation is as follows: Please refer to the third and fourth figures, the bottom surface of the seat 20 is supported by the top 13 of the cymbal, so the backrest 30 front 3 and the base 1 A vertical angle between the vertical lines at the rear end ι02 forms a sitting angle 0 丨. This state can provide a stable ride.

When the occupant wants to lie back, that is, because the back applies pressure to the backrest 30, the backrest 30 is centered on the pivot joint 33 and is between the rear end 102 of the base 10. Rotate and move the linking part 4 through the connecting part 34 while sliding on the chute & 同时 at the same time. When the linking member 40 is driven by the connecting portion 34 with its sliding groove 41, the other end of the linking member 40 is used to push the seat 20 to the bottom edge of the rear edge 22 of the seat 20, so that the front edge of the seat 20 The left and right sides of the part 21 are pivots, which rotate between the rear foot group 12 of the female 102 and the female 102; of course, during this action, because the backrest 30 is tilted back greatly Therefore, the backrest 30 front and 31 disks ", ^ the sitting angle 0 between the vertical lines of the rear end 102 is expanded to a lying angle; the angle / 9 2, and let the occupant fully comfortable lying flat;

In more detail, this work uses a link to pivot at the connection between the rear edge portion and the backrest, and let the pivot of the front edge portion of the seat, respectively, with the base # Front and back swing: j 'this way, when the occupant is sitting, due to the main gravity ...

Page 9 M245872 IV. Creation instructions (6) However, when changing from a sitting position to a lying position, 'the external force on the front of the backrest is greater than that of the seat. The included angle is enlarged to the lying angle, and the connecting part is pushed by the link to push the seat to make the seat counterclockwise with the front end of the base as the axis. In this way, the occupant can directly lie on the seat to change the sitting angle with the most single structure by lying down and pressing on the back. Coincidentally, please refer to FIG. 5A and FIG. 6A, which are another embodiment of the present creation. In this embodiment, the connecting portion 34 is two plate bodies, and 2 respectively protrudes from the plate body. On the pivotal joints 33 on both sides of the backrest 30, the two connecting parts ^ both penetrate a slideway 341, which is slightly arc-shaped, and its arc-shaped opening faces the seat 20. The front edge portion 21 allows the backrest 30 to be pivotally connected to the rear end 102 of the base 10 with the connection portion 34, and the slide rails 341 extend outward from the two sides of the rear edge portion 22 of the seat 20 respectively. Convex particles 23. ^ ^ Like ’When seated, the base 10 and the rear end 102 of the base 20 and the bump 2 of the seat 20 create a first distance R1 (see Figure 5B for cooperation). And ^ because the Philippine back 30 front 31 is stressed, that is, through the slippage and displacement of the connecting portion 34 to push the convex particles 23 of the seat 20, so that the seat 20 on the base 1 〇Before her 1 λ jj & 1 0 1, the front edge portion 21 was used as the axis, and the convex particles 23 were used to slide in the slide 341 for the connecting person ▲ for 4 34 to generate the backrest. 30 Simultaneously change the movement of the angle 仏 X, and make the base 〇〇 rear 1 〇 2 and the convex part 2 3 of the seat 20 reduced from the 4th distance to R ^ to the second distance R 2 ( (See Figures / and B for cooperation), and the first distance R1 minus the second distance R2 is the seat: 2 strokes of the swing, & this is the equivalent replacement structure of this creation. Tian Ran In this embodiment, it can be clearly seen that the seat 200M245872 4. Creation instructions (the front and rear edges 21 and 22 of Ό are roughly on the front and rear edges of the base 10. Acting between 101 and 10 2 'So' Another embodiment that changes the pivotal relationship between the front and rear edge portions 21 and 22 of the seat 20 upside down is an easy-to-think design. For example, the seventh to the ninth As shown in the figure, in this another embodiment, the two connecting portions 3 4 and its sliding 3 4 1 are directly formed on the front end 1 〇 丨 of the base, and the convex particles 2 3 are paired today. The slideway 3 4 1 should be formed on both sides of the front edge portion 2 1 of the seat 20, and the rear edge portion 22 of the seat 20 directly forms a pivotable pivotal connection with the backrest 3 pivot portion 33. The two sides of the backrest 30 are pivotally connected to the rear end 102 of the base 10.

In this way, when the backrest 30 is subjected to a force due to the lying position, the backrest 30 swings around the rear end 1 2 of the base 10, and pivots with the pivot 3 3 Push the rear edge portion 22 of the seat 20, so that the front edge portion 21 of the seat 20 passes through the two bumps 23, and moves back and forth on the base 10 according to the slideway 34 丨 ' This is also the equivalent replacement structure for this creation. The part of this creation that is superior to the conventional structure is as follows:% ^ 1] The seat and backrest are synchronized and ergonomic. In terms of this creation ^ ^ ί, as long as the back is pressed against the front of the backrest, the pivotal connection of the backrest immediately pushes the seat to sway without any additional adjustment,

Two = sitting or lying position, the seat and backrest naturally produce a pole-Fu y ergonomic angle, of course, more comfortable in riding. The linkage 2] point-type connection is conducive to joint point activities. The pole joint of the backrest and η " between the 'and the linking member and the rear edge of the seat are all black-occupied pivot joints', Hyt, and Tirana are also examples. The one-point convex particles are in the chute ^, so as long as the backrest is tilted back, a simple and rapid synchronous operation will be generated.
