[0029] Among them, Figure 3 a reference direction coordinate system for the embodiments of the present utility model is given. The following will describe the embodiments of the present utility model in combination with Figure 3 the directions shown.
[0030] The embodiments of the present utility model provide a lifting furniture, and the lifting furniture includes but is not limited to a tea table, a cabinet, etc.
[0031] See Figure 1 、 Figure 2 、 Figure 3, The lifting furniture includes a furniture main body 100, a panel 200, a lifting mechanism 300, and an auxiliary support mechanism 400. The panel 200 is disposed on the top of the furniture main body 100. The lifting mechanism 300 includes a first bracket 301 and a second bracket 302. The first bracket 301 and the second bracket 302 are connected between the furniture main body 100 and the panel 200. The first bracket 301 and the second bracket 302 are arranged in parallel and form a parallelogram mechanism with the furniture main body 100 and the panel 200. By means of the parallelogram mechanism, the panel 200 can be opened and lifted to the side of the furniture main body 100. The auxiliary support mechanism 400 includes a support member 401. The support member 401 is supported on the bottom of the furniture main body 100. The support member 401 can be retracted into the furniture main body 100 or opened to the side of the furniture main body 100 to support the furniture main body 100 in the direction in which the panel 200 is opened.
[0032] Combined with Figures 1-3 , the panel 200 of the lifting furniture forms a parallelogram mechanism with the furniture main body 100 and the panel 200 by means of the first bracket 301 and the second bracket 302, and can be opened and lifted to the side of the furniture main body 100 to achieve the lifting function. During this period, the lifted panel 200 will be offset to one side of the furniture main body 100. At this time, the support member 401 can be opened to the side of the furniture main body 100 to support the furniture main body 100 in the direction in which the panel 200 is opened, that is, the auxiliary support mechanism 400 extends an auxiliary fulcrum on the side where the panel 200 is opened, realizing the function of moving the fulcrum outward, thereby solving the problem of the furniture main body 100 tipping over. When the panel 200 descends on the top of the furniture main body 100 through the parallelogram mechanism, the support member 401 can be retracted into the furniture main body 100 again, ensuring that the appearance remains unchanged when the panel 200 is in the closed state.
[0033] It can be understood that one or more support members 401 can be provided.
[0034] Among them, the support member 401 can be installed on the furniture main body 100 in a hinged manner, so as to be retracted into the furniture main body 100 or opened to the side of the furniture main body 100 in a swinging manner.
[0035] The support member 401 can also be installed on the furniture main body 100 in a sliding rail manner, so as to be retracted into the furniture main body 100 or opened to the side of the furniture main body 100 in a telescopic manner.
[0036] In some embodiments, see Figure 3 、 Figures 5-7, the support member 401 extends from the first end 402 to the second end 403 in the longitudinal direction. A vertical first pin shaft 404 is provided between the first end 402 and the second end 403 of the support member 401. The support member 401 is installed at the bottom of the furniture main body 100 through the first pin shaft 404. The second end 403 of the support member 401 can rotate around the first pin shaft 404 to be retracted into the furniture main body 100 or opened to the side of the furniture main body 100. In this embodiment, the support member 401 can be retracted into the furniture main body 100 by swinging, ensuring that the appearance remains unchanged when the panel 200 is in the closed state.
[0037] Further, referring to Figure 3 , the support member 401 is provided with rollers 405, and the state switching can be carried out more smoothly by means of the rollers 405.
[0038] In some embodiments, referring to Figure 3 , an ear seat 406 is provided at the first end 402 of the support member 401. A tension spring 407 is connected between the furniture main body 100 and the ear seat 406. The furniture main body 100 is provided with a lock catch that cooperates with the support member 401. When the support member 401 is retracted into the furniture main body 100, the support member 401 overcomes the elastic force of the tension spring 407 and is locked and positioned by the lock catch; when it is necessary to open the support member 401 to the side of the furniture main body 100, the lock catch is unlocked to release the support member 401. The support member 401 automatically rotates around the first pin shaft 404 under the action of the tension spring 407, so as to open to the side of the furniture main body 100. Among them, the ear seat 406 for installing the tension spring 407 and the ejected support rod are in a straight line, ensuring that under the action of the tension spring 407, the spring has a pulling force and automatically opens in place, so that the support member 401 will not swing arbitrarily left and right. Even if there is an unintentional left and right displacement, it can be tightened under the action of the spring and continue to maintain the vertical open state, and there is no need to additionally set the positioning structure of the support member 401 in the open state.
[0039] Further, the lock catch is used to lock or release the support member 401. In some embodiments, referring to Figure 4, the latch includes a groove block 408. A limiting groove 409 for cooperating with the first end 402 of the support member 401 is provided on the side wall surface of the groove block 408. The limiting groove 409 is L-shaped. A side opening 410 for the first end 402 of the retracted support member 401 to be inserted into the limiting groove 409 is provided on the side of the groove block 408. A bottom opening 411 for the first end 402 of the support member 401 to escape from the limiting groove 409 is provided at the bottom of the groove block 408. When the support member 401 is retracted, the support member 401 is rotated around the first pin shaft 404, and the first end 402 of the support member 401 is inserted into the limiting groove 409 from the side opening 410 of the groove block 408 and is stuck in the limiting groove 409. When the support member 401 needs to be opened, the groove block 408 is controlled to be lifted, and the support member 401 disengages from the groove block 408 through the bottom opening 411 of the limiting groove 409 and is opened outward under the action of the tension spring 407.
[0040] Among them, referring to Figure 4 , a flap 412 that can be opened unidirectionally toward the inside of the limiting groove 409 is provided on the inner side of the side opening 410 of the groove block 408. The flap 412 can only be opened inward, so that the support rod will not pop out, achieving low cost and effectiveness.
[0041] In some embodiments, referring to Figure 3 、 Figures 5-7, one end of the first bracket 301 connected to the furniture main body 100 is connected to the groove block 408 through a link assembly. The link assembly includes a first link 501 and a second link 502. One end of the first link 501 is hinged to the first bracket 301, the other end of the first link 501 is hinged to one end of the second link 502, the second link 502 is installed on the furniture main body 100 through a second pin shaft 503, the other end of the second link 502 is hinged to the groove block 408, and the second link 502 forms a lever action through the second pin shaft 503 to amplify the movement track of the first bracket 301, so that the groove block 408 can obtain a larger movement amplitude when the bracket rises and falls, and the actions are synchronous. The groove block 408 is provided with a vertical guide groove 413, and the furniture main body 100 is provided with a guide pin 414 that cooperates with the guide groove 413. During the opening process of the panel 200, under the action of the link assembly: the groove block 408 moves obliquely upward, the support member 401 disengages from the bottom of the groove block 408, and is pulled by the tension spring 407, and the support member 401 pops out. In this way, when the panel 200 is opened, the support member 401 will surely pop out synchronously to ensure that it will not tip over. During the closing process of the panel 200, when the panel 200 is closed, the first bracket 301 drives the groove block 408 to move obliquely downward through the link assembly, manually closes the support member 401, and makes the support member 401 snap into the limit groove 409 of the groove block 408. When the panel 200 is closed, the groove block 408 descends to the lowest point, and the short side of the support member 401 opens the flap 412 and enters from the side opening 410. Because the flap 412 opens inward, the support member 401 will not pop out outward.
[0042] Through the component structure, the movements of the first bracket 301 and the second bracket 302 are converted into the reciprocating up and down movement of the groove block 408, realizing the functions of closing and opening the support member 401. When the panel 200 is raised, the support member 401 will surely pop out, realizing synchronous outward movement of the support member 401, thereby realizing the function of outward movement of the fulcrum, so that the panel 200 will not tip over even when stressed at the edge.
[0043] The first bracket 301 and the second bracket 302 can be directly hinged to the panel 200 and the furniture main body 100, and form a parallelogram mechanism with the furniture main body 100 and the panel 200.
[0044] In some embodiments, refer to Figure 3 、 Figure 5, the furniture main body 100 is provided with a first mounting plate 303, the panel 200 is provided with a second mounting plate 304, the first bracket 301 and the second bracket 302 are connected between the first mounting plate 303 and the second mounting plate 304, and the first bracket 301, the second bracket 302, the first mounting plate 303 and the second mounting plate 304 form a parallelogram mechanism. In this embodiment, the first mounting plate 303 and the second mounting plate 304 can be pre-assembled with the first bracket 301 and the second bracket 302 into a component, and then connected to the furniture main body 100 and the panel 200. The assembly is more convenient, and it is more helpful for the installation accuracy of the lifting mechanism 300.
[0045] See Figure 3 , at least one of the first bracket 301 and the second bracket 302 is provided with a limit pin 305, and the first mounting plate 303 is provided with an arc-shaped limit groove 307 that cooperates with the limit pin 305 for limiting the maximum opening angle of the panel 200.
[0046] In some embodiments, see 3, Figure 5 , a gas rod 306 is provided between the furniture main body 100 and the first bracket 301 or the second bracket 302. The gas rod 306 is used for the auxiliary support and positioning of the panel 200 to ensure the stability after rising or falling.
