Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to a multifunctional armrest for seats. Background Art

[0002] Existing seats are generally equipped with armrests to provide support for the user's arms and improve the comfort of sitting. In order to enrich the functions of the armrests, some existing seats are designed with rotatable, liftable and movable armrests to facilitate users to adjust; however, the rotation and movement of such armrests are all horizontally rotated and horizontally moved in the horizontal plane; the backrests of most existing seats can be adjusted relative to the seat, but the backrest and armrests are two separate components, and the armrests are generally set on both sides of the seat. When the user leans back, the backrest rotates backward. Since the armrests can only be adjusted in the horizontal plane, when the person adjusts the elevation angle of the seat, the seat armrests cannot be adjusted synchronously with the seat backrest, which greatly reduces the comfort. In addition, for some users who often read or play mobile games in the seat, the user likes to sit in the seat for a long time to operate the game, and the user's hands need to be placed diagonally on the chest to operate the game; and the existing armrests are undoubtedly unable to effectively support the user's elbows, so that the elbows can only be suspended; after a long time, it is easy to feel sore and tired.

[0003] In order to solve the above problems, the patent previously applied by the inventor provides an armrest and a seat (application number: CN202223604766.X), in which a rotating connection is arranged between the armrest panel and the supporting body, and the bottom end of the rotating connection is provided with a first rotating inclined surface inclined relative to the horizontal plane, and the upper end surface of the supporting body is correspondingly inclined to form a second rotating inclined surface. When the armrest panel is rotated relative to the supporting body from the horizontal supporting position, under the rotation guiding action between the first rotating inclined surface and the second rotating inclined surface, the armrest support surface formed at the top of the armrest panel changes its angle at the same time, so that the armrest can provide the user with the armrest support requirements under different usage conditions.

[0004] Although the above scheme can satisfy the different usage conditions of users through the angle change when the armrest panel rotates, it is well known that different users often have different body shapes and usage habits, which makes the arm positions of different users different when they are sitting upright or lying on their backs; because the armrest panel of the above-mentioned chair cannot be further slid or flipped relative to the rotating connector, when the user's arm is too far forward or too far back from the armrest panel, or the arm inclination angle does not match the armrest panel inclination angle, the armrest panel cannot be slid or flipped to fit the user's arm. In summary, the armrest of the above scheme has insufficient adjustment freedom. Summary of the invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a multifunctional armrest, which, in addition to being able to link with the rotating support member to rotate circumferentially relative to the supporting body, can also change its state through the active connection between the panel support member, and link the panel support member to slide back and forth against the rotating support member, so that the armrest has at least three adjustment modes, with a high degree of adjustment freedom, which can meet various usage needs of users.

[0006] The effect of the utility model is achieved in this way;

[0007] The present application provides a multifunctional armrest, comprising:

[0008] a support body disposed longitudinally and configured to be connected to a side end of the seat seat;

[0009] An armrest portion, the armrest portion is configured to support a human elbow, and a bottom end of the armrest portion is movably connected to a panel support member, so that the armrest portion can change state relative to the panel support member;

[0010] The rotating support member is obliquely arranged between the panel support member and the supporting body. The front end of the rotating support member and the panel support member are connected by a sliding mechanism, so that the armrest part can link the panel support member to slide forward and backward relative to the rotating support member; the rear end of the rotating support member and the supporting body are rotationally connected, so that the armrest part can link the rotating support member to rotate circumferentially relative to the supporting body.

[0011] Furthermore, the rear end of the rotating support is rotatably connected with the supporting body through a rotating mechanism, and the rotating mechanism includes an axial connection portion provided on the rotating support and a rotating matching portion provided on the upper end of the supporting body; the axial connection portion and the rotating matching portion are butted up and down, and a first inclined surface inclined relative to the horizontal plane is provided at the bottom end of the axial connection portion, and the upper end surface of the rotating matching portion is correspondingly inclined and forms a second inclined surface; and from the back to the front, the first inclined surface and the second inclined surface are both inclined forward and upward; the armrest portion has a horizontal supporting position in which the supporting surface at the top tends to be horizontal, and in this horizontal supporting position, the first inclined surface and the second inclined surface coincide; and when the armrest portion rotates relative to the supporting body from the horizontal supporting position, the rotational guidance between the first inclined surface and the second inclined surface causes the angle of the supporting surface to change simultaneously. By tilting the first inclined surface and the second inclined surface, when the armrest portion is linked to the rotating support member and rotates relative to the supporting body, the angle of the supporting surface on the armrest portion will change synchronously due to the rotational guidance of the first inclined surface and the second inclined surface, so that when the user is in a backward state, the user's arms and elbows can also be effectively supported.

[0012] Furthermore, in the horizontal support position, the rotating support member is tilted forward and upward, so that when the rotating support member rotates, the armrest portion connected to the front end thereof will be displaced instead of rotating in place.

[0013] Furthermore, the rotating mechanism also includes a rotating shaft disposed on the second inclined surface and protruding upward, and an axial hole correspondingly disposed on the first inclined surface, the rotating shaft rotatably penetrates the axial hole; and a first mounting groove is concavely disposed at the upper end of the shaft connection portion and passes through the axial hole vertically, and a rotation limiter fixedly connected to the rotating shaft is disposed in the first mounting groove. Through the rotational cooperation between the rotating shaft and the axial hole, the rotating support can rotate around the supporting body, and the rotating shaft cannot be separated from the axial hole due to the restriction of the rotation limiter, thereby improving the stability of the connection between the rotating support and the supporting body.

[0014] Furthermore, a first gear adjustment mechanism is provided between the rotation limiter and the shaft connection portion; the rotation limiter is a cam structure, the rotation limiter has a contraction end in a contraction shape, and the first gear adjustment mechanism includes a plurality of first gear slots recessed on the bottom wall of the first installation slot and a first limiting protrusion correspondingly provided at the bottom end of the contraction end; the first gear slots are arranged in an arc shape in the first installation slot; and the rotation limiter is configured to make the first limiting protrusion squeeze-fit with the bottom wall of the first installation slot. When the rotation limiter rotates relative to the supporting body, the first limiting protrusion will be sequentially inserted into the plurality of first gear slots, so that the rotation limiter can stay in multiple rotation positions during rotation, and the gear sense is obvious.

[0015] Furthermore, the front end of the panel support extends forward to form a sliding part, and the front end of the rotating support extends forward to form a sliding support part, and the sliding part and the sliding support part are fitted up and down; the sliding mechanism includes a mounting protrusion and a sliding groove that slide with each other, the mounting protrusion is arranged on one of the sliding part and the sliding support part, and the sliding groove is arranged on the other of the sliding part and the sliding support part. The panel support and the rotating support are slidably connected through the sliding part and the sliding support part extending from the front end, so that the panel support can slide a longer distance relative to the rotating support; and the mounting protrusion penetrates into the sliding groove, which not only slides smoothly, but also prevents the sliding part from detaching from the sliding support part when sliding, thereby ensuring the connection stability.

[0016] Furthermore, the sliding groove is provided at the bottom end of the sliding part, the mounting protrusion is provided at the top end of the sliding support part, the mounting protrusion is penetrated in the sliding groove, the upper end of the sliding part is recessed with a second mounting groove which is vertically connected with the sliding groove, and a sliding stopper fixedly connected with the mounting protrusion is provided in the second mounting groove. The mounting protrusion is restricted by the sliding stopper and cannot be separated from the sliding groove, thereby further improving the stability of the connection between the sliding part and the sliding support part.

[0017] Furthermore, a second gear adjustment mechanism is provided between the sliding stopper and the sliding part, and the second gear adjustment mechanism includes a plurality of second gear slots recessed on the side wall of the second mounting slot and a second limiting protrusion correspondingly provided on the side wall of the sliding stopper; the second gear slots are arranged on the side wall of the second mounting slot in a front-to-back direction; and the sliding stopper is configured to squeeze and fit the second limiting protrusion and the side wall of the second mounting slot. When the sliding part slides forward and backward relative to the sliding support part, the second limiting protrusion will be sequentially inserted into the plurality of second gear slots, and then the sliding part can stay in multiple sliding positions during the sliding process, and the gear sense is obvious.

[0018] Furthermore, the left and right side walls of the second mounting groove are both recessed with second gear grooves, the left and right side walls of the sliding limiter are both correspondingly provided with second limit protrusions, the two second limit protrusions are connected by an elastic member, and the two second limit protrusions always have a tendency to be squeezed toward the side wall of the second mounting groove under the elastic force of the elastic member. By providing the second gear adjustment mechanism on both the left and right sides of the sliding limiter and the second mounting groove, when the sliding part slides, the force between the sliding limiter and the second mounting groove is more balanced, and the sliding operation is smoother.

[0019] Furthermore, the rear end of the armrest is hinged to the rear end of the panel support, so that the armrest can be flipped up and down relative to the panel support. When the inclination angle of the armrest does not match the angle of the user's arm, the angle of the upper support surface of the armrest can be further adjusted by flipping the armrest up and down, so that the user's arm can naturally fit the support surface, and the support experience is more comfortable.

[0020] The beneficial effects of the multifunctional armrest provided by the present application are achieved in the following ways: when the user switches between a sitting upright or a reclining state, the armrest portion rotates circumferentially relative to the support body by linking with the rotating support member, thereby changing the angle of the support surface at the top end of the armrest portion, so that the state of the armrest portion fits the user's use state; and, when the user's arm is too far forward or too far back from the armrest portion, the armrest portion can also link with the panel support member to slide back and forth against the rotating support member, thereby changing the front and rear position of the armrest portion, ensuring that the user's arm can be supported by the armrest portion; not only that, when the inclination angle of the user's arm and the armrest portion does not match, the armrest portion can also change its state through the active connection between the panel support member, so that the armrest portion can be flipped forward and backward or left and right until the inclination of the armrest portion and the user's arm are consistent, providing a comfortable support experience; in summary, the armrest portion has at least three adjustment methods with a high degree of adjustment freedom, which can meet various usage needs of users.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0035] The present application embodiment provides a multifunctional armrest, such as Figure 1-11 As shown, including:

[0036] A support body 1 , the support body 1 is longitudinally arranged and configured to be connected to a side end of a seat seat;

[0037] An armrest portion 2, the armrest portion 2 is configured to support a human elbow, and a panel support 210 is movably connected to the bottom end of the armrest portion 2, so that the armrest portion 2 can change state relative to the panel support 210;

[0038] The rotating support member 3 is obliquely arranged between the panel support member 210 and the supporting body 1. The front end of the rotating support member 3 and the panel support member 210 are connected by a sliding mechanism, so that the armrest portion 2 can link the panel support member 210 to slide back and forth relative to the rotating support member 3; the rear end of the rotating support member 3 and the supporting body 1 are rotationally connected, so that the armrest portion 2 can link the rotating support member 3 to rotate circumferentially relative to the supporting body 1.

[0039] In this embodiment, when the user switches between the sitting upright and reclining use states, the armrest portion 2 rotates circumferentially relative to the support body 1 by linking with the rotating support member 3, thereby changing the angle of the top support surface 201 of the armrest portion 2, so that the state of the armrest portion 2 fits the use state of the user; and, when the user's arm is too far forward or too far back from the armrest portion 2, the armrest portion 2 can also link with the panel support member 210 to slide back and forth against the rotating support member 3, thereby changing the front and back position of the armrest portion 2, ensuring that the user's arm can be supported by the armrest portion 2; not only that, when the inclination angle of the user's arm and the armrest portion 2 is inconsistent, the armrest portion 2 can also change its state through the active connection between the panel support member 210, so that the armrest portion 2 can be flipped forward and backward or left and right until the inclination of the armrest portion 2 and the user's arm is consistent, providing a comfortable support experience; in summary, the armrest portion 2 has at least three adjustment methods, with a high degree of adjustment freedom, which can meet various usage needs of users.

[0040] In some embodiments of the present application, the rear end of the rotating support member 3 and the supporting body 1 are rotatably connected via a rotating mechanism, and the rotating mechanism includes an axial connection portion 310 arranged on the rotating support member 3 and a rotating matching portion arranged on the upper end of the supporting body 1; the axial connection portion 310 is butted against the rotating matching portion 110 up and down, and a first inclined surface 311 inclined relative to the horizontal plane is provided at the bottom end of the axial connection portion 310, and the upper end surface of the rotating matching portion 110 is correspondingly obliquely arranged to form a second inclined surface 111; and from back to front, the first inclined surface 311 and the second inclined surface 111 are both inclined forward and upward; the armrest portion 2 has a horizontal supporting position in which the supporting surface 201 at its top end tends to be horizontal, and in this horizontal supporting position, the first inclined surface 311 and the second inclined surface 111 coincide with each other; and when the armrest portion 2 rotates relative to the supporting body 1 from the horizontal supporting position, the rotation guide between the first inclined surface 311 and the second inclined surface 111 causes the supporting surface 201 to change its angle at the same time.

[0041] In this embodiment, the first inclined surface 311 and the second inclined surface 111 are inclined so that when the armrest 2 is linked with the rotating support member 3 to rotate circumferentially relative to the support body 1, the angle of the support surface 201 on the armrest 2 will change synchronously under the rotational guidance of the first inclined surface 311 and the second inclined surface 111. Specifically, when the armrest 2 in the horizontal support position rotates backward 180° relative to the support body 1, the first inclined surface 311 still matches the second inclined surface 111 after rotating 180°, and when the armrest 2 rotates backward, the support surface 201 at the upper end of the armrest 2 is converted to a state of being high in the front and low in the back; so that the change of the armrest 2 at this time can just cater to the position of the user's arm in the backward state, so that the user's arms and elbows can also be effectively supported in the backward state.

[0042] Preferably, the first inclined surface 311 and the second inclined surface 111 are ellipses with the same contour, and the major axis of the second inclined surface 111 coincides with the front-to-back direction, so that when the rotating support 3 rotates backward 180°, the armrest 2 will remain in the front-to-back direction again.

[0043] In some embodiments of the present application, in the horizontal support position, the rotating support member 3 is tilted forward and upward, so that when the rotating support member 3 rotates, the armrest portion 2 connected to the front end thereof will be displaced, and after the displacement, the front end of the armrest portion 2 is offset toward the rear and downward, and the support surface 201 on the armrest portion 2 can be converted to a state of high front and low back, which is suitable for the user to use in a backward state, rather than rotating in place.

[0044] In some embodiments of the present application, the rotating mechanism further includes a rotating shaft 112 disposed on the second inclined surface 111 and protruding upward, and an axial hole 312 correspondingly disposed at the first inclined surface 311, wherein the rotating shaft 112 is rotatably disposed in the axial hole 312; and a first mounting groove 313 penetrating the axial hole 312 from top to bottom is concavely disposed at the upper end of the shaft connection portion 310, and a rotation stopper 320 fixedly connected to the rotating shaft 112 is disposed in the first mounting groove 313. Through the rotational cooperation between the rotating shaft 112 and the axial hole 312, the rotating support member 3 can rotate around the supporting body 1, and by arranging the rotation stopper 320 in the first mounting groove 313 and fixing it in connection with the rotating shaft 112, the rotating shaft 112 is restricted by the rotation stopper 320 and cannot be separated from the axial hole 312, thereby improving the stability of the connection between the rotating support member 3 and the supporting body 1.

[0045] Among them, a clamping block 113 protruding upward is provided at the upper end of the rotating shaft 112, and the clamping block 113 is located in the first installation groove 313; the bottom end of the rotation limiter 320 is correspondingly provided with a clamping groove 323 capable of clamping with the clamping block 113, and the rotation limiter 320 is embedded in the first installation groove 313 so that the clamping block 113 is clamped in the clamping groove 323, and further a longitudinal screw is connected between the rotation limiter 320 and the rotating shaft 112. Then the rotation limiter 320 and the rotating shaft 112 are fixed in the circumferential direction, and the two are connected and fixed by screws, so that the installation and disassembly operations between the rotation limiter 320, the rotating support member 3 and the supporting body 1 are also more convenient.

[0046] Among them, preferably, the side wall of the clamping block 113 presents a wavy protrusion, and the groove wall of the clamping groove 323 also presents a wavy depression accordingly, so that after the clamping block 113 and the clamping groove 323 are clamped together, the rotation limit member 320 cannot rotate circumferentially relative to the rotating shaft 112, and the connection is relatively stable.

[0047] In some embodiments of the present application, a first gear adjustment mechanism is further provided between the rotation limit member 320 and the shaft connection portion 310; the rotation limit member 320 is a cam structure, and the rotation limit member 320 has a contraction end 321 in a contraction shape, and the first gear adjustment mechanism includes a plurality of first gear grooves 314 recessed on the bottom wall of the first mounting groove 313 and a first limiting protrusion 322 correspondingly arranged at the bottom end of the contraction end 321; the first gear grooves 314 are arranged in an arc shape in the first mounting groove 313; and the rotation limit member 320 is configured to make the first limiting protrusion 322 squeeze-fit with the bottom wall of the first mounting groove 313.

[0048] In this embodiment, the rotation limit member 320 is circumferentially fixed to the support body 1. When the rotation limit member 320 rotates relative to the support body 1, the first limit protrusion 322 will rotate relative to the trajectory of the first gear groove 314. The first limit protrusion 322 will be inserted into several first gear grooves 314 in turn, so that the rotation limit member 320 can stay in multiple rotation positions during the rotation process, and the gear sense is obvious.

[0049] Among them, a first baffle 315 is provided on the upper cover of the first installation groove 313, so that the first gear adjustment mechanism and the rotation limit member 320 in the first installation groove 313 are blocked by the first baffle 315. In appearance, the first baffle 315 and the rotating support member 3 are connected as a whole, thereby improving the aesthetics.

[0050] In some embodiments of the present application, the front end of the panel support 210 extends forward to form a sliding portion 220, and the front end of the rotating support 3 extends forward to form a sliding support portion 330, and the sliding portion 220 and the sliding support portion 330 are fitted together up and down; the sliding mechanism includes a mounting protrusion 331 and a sliding groove 221 that slide with each other, the mounting protrusion 331 is arranged on one of the sliding portion 220 and the sliding support portion 330, and the sliding groove 221 is arranged on the other of the sliding portion 220 and the sliding support portion 330.

[0051] In this embodiment, the panel support 210 and the rotating support 3 are slidably connected by the sliding portion 220 and the sliding support portion 330 extending from the front end, so that the panel support 210 can slide a longer distance relative to the rotating support 3; and the sliding portion 220 and the sliding support portion 330 are slidably connected by the mounting protrusion 331 and the sliding groove 221, and the mounting protrusion 331 penetrates into the sliding groove 221, which not only slides smoothly but also prevents the sliding portion 220 from detaching from the sliding support portion 330 when sliding, thereby ensuring the stability of the connection.

[0052] In some embodiments of the present application, the sliding groove 221 is opened at the bottom end of the sliding part 220, the mounting protrusion 331 is arranged at the top end of the sliding support part 330, the mounting protrusion 331 is penetrated in the sliding groove 221, and the upper end of the sliding part 220 is recessed and provided with a second mounting groove 222 which passes through the sliding groove 221 from top to bottom, and the second mounting groove 222 is provided with a sliding limiter 340 fixedly connected to the mounting protrusion 331.

[0053] In this embodiment, a sliding limiter 340 is provided in the second mounting groove 222 and fixedly connected to the mounting protrusion 331, so that the mounting protrusion 331 is restricted by the sliding limiter 340 and cannot be separated from the sliding groove 221, thereby further improving the stability of the connection between the sliding part 220 and the sliding support part 330.

[0054] The sliding limiter 340 and the mounting protrusion 331 are connected and fixed by longitudinal screws, so that the installation and disassembly operations between the sliding limiter 340 and the mounting protrusion 331 are convenient.

[0055] In some embodiments of the present application, a second gear adjustment mechanism is arranged between the sliding limit member 340 and the sliding portion 220, and the second gear adjustment mechanism includes a plurality of second gear grooves 223 recessed on the side walls of the second mounting groove 222 and second limiting protrusions 341 correspondingly arranged on the side walls of the sliding limit member 340; the second gear grooves 223 are arranged along the front-to-back direction on the side walls of the second mounting groove 222; and the sliding limit member 340 is configured to squeeze the second limiting protrusions 341 and the side walls of the second mounting groove 222 into a fit.

[0056] In this embodiment, the sliding limit member 340 is fixed relative to the sliding support portion 330, and then when the sliding portion 220 slides forward and backward relative to the sliding support portion 330, the second limit protrusion 341 will slide forward and backward relative to the second gear groove 223, and the second limit protrusion 341 will be inserted into several second gear grooves 223 in turn, so that the sliding portion 220 can stay in multiple sliding positions during the sliding process, and the gear feeling is obvious.

[0057] In some embodiments of the present application, the left and right side groove walls of the second mounting groove 222 are both recessed with a second gear groove 223, and the left and right side walls of the sliding limit member 340 are respectively provided with a second limit protrusion 341, and the two second limit protrusions 341 are connected by an elastic member. Under the elastic force of the elastic member, the two second limit protrusions 341 always have a tendency to be squeezed toward the side wall of the second mounting groove 222.

[0058] In this embodiment, by arranging the second gear adjustment mechanism on the left and right sides of the sliding limit member 340 and the second mounting groove 222, when the sliding part 220 slides, the force between the sliding limit member 340 and the second mounting groove 222 is more balanced, and the sliding operation is smoother; and the two second limit protrusions 341 are connected by an elastic member, so that the two second limit protrusions 341 have a tendency to be squeezed toward the side wall of the second mounting groove 222, and the structure is simple.

[0059] Among them, the upper end cover of the second installation groove 222 is provided with a second baffle 224, so that the second gear adjustment mechanism and the sliding limit member 340 in the second installation groove 222 are blocked by the second baffle 224. In terms of appearance, the second baffle 224 and the panel support member 210 are connected as a whole to improve the aesthetics.

[0060] In some embodiments of the present application, the rear end of the armrest portion 2 is hinged to the rear end of the panel support 210 , so that the armrest portion 2 can be flipped up and down relative to the panel support 210 .

[0061] In this embodiment, when the inclination angle of the armrest portion 2 does not match the angle of the user's arm, the angle of the support surface 201 on the armrest portion 2 can be further adjusted by flipping the armrest portion 2 up and down, so that the user's arm can naturally fit the support surface 201, and the support experience is more comfortable.

[0062] Among them, the armrest part 2 and the panel support 210 are connected by a one-way flip self-locking mechanism, so that the armrest part 2 can be fixed to the panel support 210 when flipped to multiple angles, and the adjustment operation is convenient. The structure refers to the existing patent "A one-way flip self-locking mechanism of an armrest" (application number: 202223566557.0), and will not be elaborated in this embodiment.
