Description

Technical Field

[0001] The utility model belongs to the technical field of furniture structures, and in particular relates to a modular chair comprising a shaped sponge structure. Background Art

[0002] A modular seat is a seat structure composed of multiple, relatively independent modules, as opposed to an integrated seat. For manufacturers, modular seats offer the advantage of high production efficiency, while for users, the main advantage is low repair and replacement costs. A damaged module can be replaced individually, while the remaining modules remain functional.

[0003] On the other hand, shaped sponge refers to a fixed-shape soft sponge material used in seats. Its structure mainly consists of a seat plate and a backrest plate. Accordingly, the general shape of the shaped sponge is an obtuse "L" shape.

[0004] Furthermore, since users typically install modular chairs themselves, manufacturers often offer various adjustable features for greater adaptability and flexibility, such as adjustable backrest height. This requires the aforementioned shaped sponge to accommodate the varying backrest heights that users adjust themselves.

[0005] For example, the Chinese utility model patent with authorization announcement number CN214433071U and authorization announcement date 2021.10.22 discloses an ergonomic modular chair with a modular design, including a modular soft bag, a modular fixed plate, a seat frame, a back frame, a keel, and a foot support, wherein multiple modular soft bags are fixed on multiple corresponding modular fixed plates, and multiple modular fixed plates are fixed on the seat frame, back frame and keel in different directions according to the physiological curve of the human body, the keel is fixed on the seat frame and back frame, and the foot support is fixed on the seat frame and back frame.

[0006] The ergonomic modular chair in this utility model patent has the following general advantages: the modules constituting the seat and backrest of the chair are relatively independent, the concave and convex shapes of the modules can form a force feedback effect similar to a massage effect on the human body contact surface, and the gaps between the modules allow air to circulate, thereby playing a role in heat dissipation.

[0007] However, in actual use, the ergonomic modular chair still has at least the following two deficiencies, which are also the technical problems to be solved by the present invention, namely:

[0008] First, the seat and back frames lack the important, comfort-oriented size adjustment function, and their relative positions are fixed, which is not conducive to the practicality of the modular chair.

[0009] Second, its modular soft bag structure also lacks the necessary size adjustment function, resulting in the structure being able to only adapt to seat and back frame structures of one shape and size, which is also impractical and inconvenient.

[0010] Therefore, in summary, there is an urgent need for a new modular seat product in which the seat size itself is relatively flexible and adjustable, and the soft package material can also change its own size and always match it. Utility Model Content

[0011] The utility model provides a modular seat including a shaped sponge structure, which can be achieved by arranging a grooved lifting backboard unit and a shaped sponge unit with cutting grooves on a grooved seat unit, so that: 1. the backboard height of the modular seat is flexibly adjustable, thereby greatly improving its practicality; 2. although the shaped sponge unit with cutting grooves has a fixed shape, its size can also be adjusted by appropriate cutting, thereby ensuring that the size of the shaped sponge is always adapted to the backboard height of the modular seat.

[0012] The technical solution adopted by the present invention to solve the above-mentioned problems is: a modular seat including a shaped sponge structure, the structure including a grooved seat unit, a grooved lifting backboard unit arranged on the grooved seat unit, and a shaped sponge unit with cutting grooves which is clamped on the grooved seat unit and the grooved lifting backboard unit and is cut to match the height of the grooved lifting backboard unit.

[0013] A further preferred technical solution is that the grooved seat unit includes a transverse plate, and side grooves provided on the upper surface of the transverse plate and used for engaging and installing the shaped sponge unit with cutting grooves.

[0014] A further preferred technical solution is that the grooved lifting support plate unit includes an inclined plate, and a connecting groove that is opened upward from the lower surface of the inclined plate, docks with the side groove, and is used for clamping and installing the shaping sponge unit with cutting grooves.

[0015] A further preferred technical solution is that the shaping sponge unit with cutting grooves includes a seat sponge piece arranged on the side grooves, a backboard sponge piece arranged on the seat sponge piece and inserted into the connecting grooves, and a plurality of transverse positioning grooves for cutting arranged on the backboard sponge piece.

[0016] A further preferred technical solution is that it also includes a U-shaped handrail unit for supporting the inclined plate.

[0017] A further preferred technical solution is that the U-shaped armrest unit includes a side cross bar for supporting the inclined plate, and two armrest boards arranged on the side cross bar and located at both sides of the inclined plate.

[0018] A further preferred technical solution is that the U-shaped armrest unit further includes a rectangular groove provided on the upper surface of the armrest board and used for inserting and installing the cut backboard sponge piece.

[0019] A further preferred technical solution is that: the slotted seat plate unit also includes a screw groove arranged on the side of the horizontal plate and used to install the inclined plate; the slotted lifting backrest unit also includes a plurality of connecting holes arranged on the inclined plate and evenly spaced in a linear arrangement, and an adjusting bolt arranged on the connecting hole and used to connect the screw groove.

[0020] A further preferred technical solution is that the grooved seat unit further includes an anti-slip protruding strip arranged on the bottom surface of the side groove.

[0021] A further preferred technical solution is that the grooved lifting backboard unit further includes a limiting piece provided on the side of the communicating groove and used for clamping the backboard sponge piece. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0038] As attached Figure 1-8 As shown, a modular seat includes a shaped sponge structure, the structure includes a grooved seat unit 1, a grooved lifting backboard unit 2 arranged on the grooved seat unit 1, and a shaped sponge unit 3 with cutting grooves, which is clamped on the grooved seat unit 1 and the grooved lifting backboard unit 2 and is cut to match the height of the grooved lifting backboard unit 2.

[0039] In this embodiment, the term "fixed shape" refers to the fact that the shape of the grooved shaped sponge unit 3 is fixed. Specifically, its main characteristic is a two-section curved plate with an obtuse angle. Accordingly, the adjustment function of the grooved lift backrest unit 2, compared to the grooved seat unit 1, only includes lift adjustment, not rotation adjustment. In other words, the angle between the grooved seat unit 1 and the grooved lift backrest unit 2 remains fixed, corresponding to the aforementioned "fixed shape" characteristic.

[0040] On the other hand, the height of the grooved lifting backrest unit 2 is adjustable, and the size of the sponge unit 3 with cutting grooves can be changed after cutting, so that the latter can be adapted to the former, ensuring that every purchasing user can obtain a modular seat product that suits him or her and has an adapted internal structure.

[0041] Specifically, after the purchasing user has adjusted the height of the grooved lifting backrest unit 2 according to his own needs, the sponge unit 3 with cutting grooves can be cut so that the latter can be installed together with the grooved seat unit 1 and the grooved lifting backrest unit 2 without the phenomenon of local sponge bulging and wrinkling being too long, and without the phenomenon of sponge being too short to fill the engaging position.

[0042] The seat unit 1 with grooves includes a transverse plate 101 and a side groove 102 provided on the upper surface of the transverse plate 101 and used for engaging and installing the shaping sponge unit 3 with cutting grooves.

[0043] In this embodiment, the main body of the grooved seat unit 1 and the grooved lift back unit 2 is made of wood or plastic. The horizontal plate 101 is rectangular in shape, with three vertical sides and one inclined side. This inclined side is designed to fit over the grooved lift back unit 2, thereby achieving the inclined back effect of the modular chair. The side slots 102 are also located on this inclined side.

[0044] The three vertical sides mentioned above are: the front side of the modular seat, and two sides for setting the leg mounting grooves 12.

[0045] The grooved lifting support plate unit 2 includes an inclined plate 201 and a connecting groove 202 which is opened upward from the lower surface of the inclined plate 201 and docks with the side groove 102 and is used for clamping and installing the shaping sponge unit 3 with cutting grooves.

[0046] In this embodiment, the inclined plate 201 can slide vertically along the inclined side surface to adjust and ultimately determine the desired height. The connecting groove 202 and the side groove 102 are of equal width and aligned left and right, always engaging the shaped sponge unit 3 with the cutting groove. The width of the groove is slightly larger than the width of the shaped sponge unit 3 with the cutting groove to prevent the latter from shifting significantly left and right.

[0047] The connecting groove 202 and the side groove 102 together form an obtuse-angled "L-shaped" notch for engaging and mounting the sponge unit with cutting groove 3. The higher the side surface at the center and highest point of the connecting groove 202, the smaller the area on the sponge unit with cutting groove 3 that needs to be cut and removed, and vice versa.

[0048] At this point, the tilting plate 201 has been adjusted and fixed at the required height, and the sponge unit 3 with cutting grooves has also been engaged left and right and up and down on the connecting groove 202 and the side groove 102. The modular seat has been fully adjusted and installed, meeting the different needs of different purchasing users for seat size to the greatest extent.

[0049] Correspondingly, the angle between the transverse plate 101 and the inclined plate 201 is equal to the angle set on the sponge unit 3 with cutting grooves and factory settings.

[0050] The shaping sponge unit 3 with cutting grooves includes a seat sponge piece 301 arranged on the side groove 102, a backboard sponge piece 302 arranged on the seat sponge piece 301 and inserted into the connecting groove 202, and a plurality of transverse positioning grooves 303 for cutting arranged on the backboard sponge piece 302.

[0051] In this embodiment, the seat sponge sheet 301 and the backboard sponge sheet 302 are integrally formed, and the widths of the two are equal. The length of the former is also equal to the length of the side slot 102, and the length of the latter is the object that needs to be adjusted in the above-mentioned cutting operation.

[0052] On the other hand, the cross-sectional shape of the cutting transverse positioning groove 303 is triangular or semicircular, and is provided on both the front and back sides of the backing sponge sheet 302, and is arranged in pairs of two, with a total of 3-8 pairs. Figure 5 , ultimately ensuring that the actual length of the backrest sponge piece 302, or the actual height of the backrest sponge piece 302 is flexibly adjustable.

[0053] When the backboard sponge sheet 302 is installed on the communicating groove 202 , the exposed side thereof is the front side, and the opposite side is the back side.

[0054] It should be noted that the length cutting and adjustment method of the backboard sponge sheet 302 is stepless. If the lifting method of the inclined plate 201 on the horizontal plate 101 is stepless, the adjustment effect of the former can only be adapted to the latter as much as possible.

[0055] Specifically, there may be a small gap between the trimmed upper surface of the backboard sponge sheet 302 and the highest side surface in the center of the communicating groove 202, but this is already the optimal size matching combination.

[0056] The modular seat further includes a U-shaped armrest unit 4 for supporting the inclined plate 201 .

[0057] In this embodiment, the main function of the U-shaped armrest unit 4 is to provide support and reinforcement on the back side of the inclined plate 201 to prevent the pressure of the passenger on the inclined plate 201 from being applied entirely to the connection between the transverse plate 101 and the inclined plate 201 .

[0058] The reason why the above-mentioned function of the U-shaped handrail unit 4 is effective is that within a certain range, no matter how high the inclined plate 201 is, the U-shaped handrail unit 4 always presses against the back side thereof.

[0059] The U-shaped armrest unit 4 includes a side crossbar 401 for supporting the inclined plate 201 , and two armrest plates 402 provided on the side crossbar 401 and located at both sides of the inclined plate 201 .

[0060] In this embodiment, each of the armrest panels 402 is provided with two supporting legs 11 , the U-shaped armrest unit 4 is integrally formed, and the armrest panels 402 are appropriately clamped to the side surfaces of the inclined panel 201 .

[0061] However, it should be noted that the supporting effect of the side cross bar 401 on the inclined plate 201 has a relatively optimal range. When the height of the inclined plate 201 is relatively high, the above supporting effect is relatively general.

[0062] The U-shaped armrest unit 4 further includes a rectangular groove 403 provided on the upper surface of the armrest plate 402 and used for inserting and installing the cut backboard sponge piece 302 .

[0063] In this embodiment, after the backrest sponge sheet 302 is cut, an indefinite number of sponge cutting strips 302-1 with fixed shapes and sizes are obtained. At this time, the sponge cutting strips 302-1 are snap-fitted and installed in the rectangular groove 403, thereby improving the comfort of use of the armrest board 402.

[0064] It should be noted that:

[0065] First, if the cut sponge portion has the cutting transverse positioning groove 303, it is also necessary to cut at the groove to finally obtain the sponge cutting strip 302-1 with the same shape and size;

[0066] Second, the number of the rectangular slots 403 is 2, but the number of the sponge cutting strips 302-1 may be 0, 1, 2, or even more. Therefore, the rectangular slots 403 may be idle and cannot be equipped with the sponge cutting strips 302-1. As for the sponge cutting strips 302-1, the number may also be too many. The excess sponge cutting strips 302-1 need to be temporarily put away for later replacement.

[0067] The slotted seat unit 1 also includes a screw groove 103 arranged on the side of the horizontal plate 101 and used to install the inclined plate 201; the slotted lifting backrest unit 2 also includes a plurality of connecting holes 203 arranged on the inclined plate 201 and evenly spaced in a linear arrangement, and an adjusting bolt 204 arranged on the connecting hole 203 and used to connect the screw groove 103.

[0068] In this embodiment, the screw connection groove 103, the connection hole 203 and the adjustment bolt 204 together provide the lifting and lowering adjustment function of the inclined plate 201 with a step-by-step adjustment effect to adapt to the width of the adjacent transverse positioning grooves 303 for cutting.

[0069] At this time, the transverse plate 101 and the inclined plate 201 are screwed together by the adjusting bolts 204. There are two screw connection grooves 103 and two adjusting bolts 204, one on the left and one on the right, and the connecting holes 203 are in two rows.

[0070] Among them, the height of the inclined plate 201 corresponding to each group of the connecting holes 203 matches the actual height of the sponge sheet after several sponge cutting strips 302-1 are cut out from the backboard sponge sheet 302, ensuring that the upper surface of the backboard sponge sheet 302 and the highest side surface in the center of the connecting groove 202 can always be matched and fitted, with no obvious gap and no bulging of the sponge.

[0071] The grooved seat unit 1 further includes an anti-slip protruding strip 104 provided on the bottom surface of the side groove 102 .

[0072] In this embodiment, the direction of force on the seat sponge sheet 301 is backward, and the function of the anti-slip protruding strip 104 is to prevent the seat sponge sheet 301 from bending, wrinkling and sliding backward.

[0073] In other words, the function of the anti-slip protruding strip 104 is to ensure that the seat sponge sheet 301 always sticks to the front side of the seat on the side slot 102 as much as possible.

[0074] The grooved lifting backboard unit 2 further includes a limiting piece 205 provided on a side surface of the communicating groove 202 and used for clamping the backboard sponge piece 302 .

[0075] In this embodiment, there are three limit plates 205 , which are respectively provided on all three side surfaces of the communicating groove 202 , and their function is to prevent the backing plate sponge plate 302 from separating from the inclined plate 201 .

[0076] The limiting piece 205 is used to press the front side of the backboard sponge piece 302 , and the former setting does not affect the length adaptation effect between the backboard sponge piece 302 and the connecting groove 202 .

[0077] Finally, if the height of the tilt plate 201 needs to be changed after the modular seat has been used for a period of time, the backrest sponge sheet 302 can be further trimmed or the sponge trimming strip 302-1 can be refilled to ensure that the shaped sponge provides adequate and appropriate support for the occupant's back. In this case, the refilled sponge trimming strip 302-1 needs to be appropriately secured within the connecting groove 202, such as by gluing.

[0078] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications are possible within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. These modifications are non-inventive and are protected by patent law as long as they fall within the scope of the claims of the present invention.
