Description

Technical Field

[0001] The invention relates to the field of daily necessities, in particular to a chair. Background Art

[0002] At present, chairs can meet the needs of users to adjust their sitting posture and lying down to relax during work and entertainment by adjusting the backrest. However, the function of adjusting the reclining angle is still insufficient, for example:

[0003] 1. Since the overall center of gravity shifts backward seriously and cannot maintain balance when leaning back at a large angle, it is easy to cause the seat to tip over. In response to this situation, the designer usually sets a safe reclining value. On the premise of satisfying the user's ability to lean back and rest on the chair back, it also prevents the user from tipping over due to difficulty in maintaining balance when leaning back. However, this design has certain limitations. Since the safe reclining angle has a limited value, it is not conducive for users to further increase the reclining angle according to their own needs to obtain a better comfort experience.

[0004] 2. Because the chair back is not close enough to the human spine when leaning back, the limbs cannot get strong support, the human body is in a tense state and cannot be well relaxed, which greatly reduces the user experience.

[0005] Therefore, this structural setting is based on the above problems, adheres to the principles of meeting consumer needs and safe use, and further improves the existing chairs. Summary of the invention

[0035] The following is combined with Figure 1-9 , the specific implementation methods of the present invention are further described in detail to make the technical solution of the present invention easier to understand and grasp.

[0036] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "end", "front", "back", "middle", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0037] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it is not described in detail in this embodiment.

[0038] like Figure 1 , Figure 2 , Figure 6 , Figure 8 and Fig. 9 As shown, a chair comprises: a first mounting member 1 and a second mounting member 2, the second mounting member 2 is assembled with the first mounting member 1 and can rotate relative to the first mounting member 1, specifically, a first mounting portion 11 and a second mounting portion 12 are provided on the lower end surface of the first mounting member 1, a third mounting portion 13 extends from one end of the upper end surface of the first mounting member 1, a fourth mounting portion 21 and a fifth mounting portion 22 are provided at the lower end and the upper end of the second mounting member 2, respectively (in this embodiment, two of the first mounting portion 11, the second mounting portion 12, the third mounting portion 13, the fourth mounting portion 21 and the fifth mounting portion 22 are provided), and the third mounting portion 13 is hinged with the fourth mounting portion 21, so that the second mounting member 2 can rotate relative to the first mounting member 1;

[0039] like Figure 4 , Figure 6 , Figure 8 and Fig. 9 As shown, a connecting member 3, one end of which is assembled with the first mounting member 1, specifically, at least one connecting seat 31 is extended from one end of the connecting member 3 (in this embodiment, two connecting seats 31 are provided), and a supporting member 32 is extended upward from the other end, and a first connecting portion 311 and a second connecting portion 312 are provided on the connecting seat 31, and the first connecting portion 311 is assembled with the first mounting portion 11, so that the connecting member 3 is assembled with the first mounting member 1;

[0040] like Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, a first cushion body 4, one end of which is assembled with the connecting member 3 on its surface, and the other end is assembled with the second mounting member 2. When the first cushion body 4 is subjected to an external force (specifically, the force applied by the user when leaning back), the first cushion body 4 can rotate relative to the connecting member 3, and the second mounting member 2 supports the first cushion body 4. Specifically, a first support portion 41 and a second support portion 42 are provided on the surface of the first cushion body 4 (in this embodiment, two first support portions 41 and two second support portions 42 are provided), the first support portion 41 is hinged to the fifth mounting portion 22, and the second support portion 42 is hinged to the supporting member 32. When When the first cushion body 4 is subjected to external force, the first cushion body 4 rotates relative to the support member 32, and because the fifth mounting portion 22 is hinged to the first support portion 41, it can rotate with the first cushion body 4, and the second mounting portion 2 accordingly supports the first cushion body 4, so that when the user sits on the second cushion body 7 and leans back, the first cushion body 4 can effectively support the user's spine and other parts, and the user's spine and other parts obtain strong support, thereby allowing the user's limbs to be well relaxed. At the same time, if the user wants to increase or decrease the leaning back angle, the leaning back angle can be increased or decreased by replacing the second mounting portion 2 or other methods.

[0041] like Figure 3 , Figure 4 , Figure 6 , Figure 8 and Fig. 9As shown, a hollow shell 5 is provided below the first mounting member 1, and a first assembling portion 51 and a second assembling portion 52 are provided on opposite side walls of the hollow shell 5 (in this embodiment, the first assembling portion 51 is an arc-shaped hole, and the second assembling portion 52 is a block). A reset device is provided in the hollow shell 5 between the first assembling portion 51 and the second assembling portion 52, which includes an adjusting rod 53 and a spring 531 sleeved on the adjusting rod 53 (in this embodiment, the adjusting rod 53 is a telescopic rod). The first assembling portion 51 is combined with the second connecting portion 312, and the connecting portion 312 is connected to the first assembling portion 51. The connecting seat 31 can reciprocate relative to the first assembling part 51, and the second assembling part 52 is assembled with the second mounting part 12. When the user applies external force to the connecting member 3, the connecting seat 31 moves from one side of the first assembling part 51 to the other side (at this time, the adjusting rod 53 and the spring 531 are in a compressed state), and the connecting seat 31 tilts. The first assembling part 51 not only ensures the safety of the tilting angle, but also plays a role of limiting, effectively maintaining the balance of the user's body to prevent backward tipping, etc., and also because the first cushion body 4 rotates relative to the support member 32 and the second mounting member 2 is combined with the first cushion body 4, so that at the original safe reclining angle, the first cushion body 4 can continue to rotate relative to the support member 32, the center of gravity of the human body naturally moves forward, and the first cushion body 4 pushes the human body (mainly the waist) forward, so that the user can continue to increase the reclining angle at the original safe reclining angle (because the position of the support member 32 does not change when the first cushion body 4 rotates relative to the support member 32, the user continues to adjust the reclining angle within the safe range, making the adjustment very safe and stable), improving the user's comfort experience, and because the second mounting member 2 at this time The first cushion body 4 is supported, and the first cushion body 4 effectively supports the spine and other parts of the user, so that the spine and other parts of the user are effectively supported, so that the user's limbs can be well relaxed; when the connecting member 3 is not subjected to external force (at this time, the adjustment rod 53 and the spring 531 are in an uncompressed state), the adjustment rod 53 and the spring 531 cooperate to reset the connecting seat 31, and the user can repeatedly apply external force to the connecting member 3 to achieve reciprocating motion, so that the spine and other parts of the human body are fully massaged, especially the waist and back parts, which can be repeatedly squeezed, thereby effectively eliminating lumbar muscle strain. In other embodiments, the adjustment rod 53 is a long rod, and a component that pushes the spring 531 is provided at one end of the long rod to cause the spring 531 to be compressed to achieve the effect of resetting. A base 6 is provided below the hollow shell 5. In this embodiment, the base 6 is a movable component so that the user can move the chair. Since the movable component is a prior art, it will not be described in detail here. In other embodiments, the base 6 can also be set to be immovable.

[0042] like Figure 7-Figure 9 As shown, a second cushion body 7 is provided on the first mounting member 1 for a user to sit on.

[0043] like Figure 1-9As shown, the use principle of the chair is: when the user sits on the second cushion body 7 and leans back, the second connecting part 312 on the connecting seat 31 moves from one side of the first assembly part 51 to the other side (at this time, the adjusting rod 53 and the spring 531 are in a compressed state), and the connecting seat 31 tilts. At this time, the angle formed by the first cushion body 4 and the supporting member 32 on the connecting member 3 increases, and the first cushion body 4 pushes the human body forward, so that the center of gravity of the human body naturally moves forward, the user's waist is lifted up by the first cushion body 4, and the second mounting member 2 supports the first cushion body 4, so that the first cushion body 4 fits the user's waist and other parts, and the user's limbs are well relaxed; when the user sits up straight, the user's back leaves the first cushion body 4 (at this time, the adjusting rod 53 and the spring 531 are in an uncompressed state), and the adjusting rod 53 and the spring 531 are reset to drive the second connecting part 312 on the connecting seat 31 back to the initial position of the first assembly part 51, so that the connecting member 3 and the first cushion body 4 are reset.

[0044] In summary, the chair of the present invention has the following beneficial effects:

[0045] 1. When the first cushion body of the present invention rotates relative to the support member, it can push the human body forward, so that the center of gravity of the human body naturally moves forward. On the basis of maintaining the balance of the user, the original reclining angle is further increased, so that the customer can get a better and more comfortable experience.

[0046] 2. The present invention allows the user to sit on the second cushion body and do reclining exercises, while the first cushion body can effectively support the user's spine and other parts, so that the user's spine and other parts are strongly supported, thereby allowing the user's limbs to be well relaxed.

[0047] 3. The present invention can make the first pad body close to the human body during the backward movement, and when the user leans back reciprocatingly, the human spine and other parts can be continuously massaged, especially the waist and back area, which can be repeatedly kneaded, thereby effectively eliminating lumbar muscle strain.

[0048] 4. The present invention is very safe and stable when the original reclining angle is further increased.

[0049] 5. The present invention is made of less costly materials, which effectively reduces the manufacturing cost.

[0050] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
