Description

Technical Field

[0001] The invention relates to the field of ergonomics, and in particular to a multifunctional bracket. Background Art

[0002] At present, when staff members are working and students are studying, computer monitors, laptops or tablets, books, bookcases, etc. are placed on the desktop, and users will be in a state of bowing their heads and bending over. Bad behavioral habits such as long-term bowing habits will increase the load-bearing pressure of the cervical and lumbar vertebrae, and the tension of the muscles and fascia nearby will change. Over time, the spine will change in curvature, scoliosis, rotation, etc. This is one of the important causes of spinal diseases. According to media reports, a survey conducted by the China Medical and Health International Exchange Promotion Association showed that the prevalence of cervical spondylosis in young and middle-aged people aged 20-40 in my country is as high as 59.1%, and even many minors are not immune.

[0003] In addition, if the display screen and books are too close to the eyes, it can easily cause damage to the eyes.

[0004] Multifunctional brackets used on workbenches are widely used in life. Most computer brackets suitable for workbenches are made of lifting platforms or lifting tables. Lifting platforms and lifting tables are placed directly on the work surface, and the area is generally smaller than the work surface. The lifting method of the lifting platform is usually to select a height first and then lock this height. If you want to readjust the height later, you need to reselect a height and then lock it. The height adjustment is usually unlimited and the height can be adjusted at will. After adjusting to the required height, you need to adjust the locking screw to fix the height at this position. The structure of most lifting tables is an inner X-shaped structure. The table top of the lifting table can generally accommodate a display screen and a notebook at the same time.

[0005] The above-mentioned existing lifting platforms and lifting tables used on workbenches are basically placed directly on the workbench and are lifted by cross-fixation. The lifting is cumbersome and makes the operating table easy to shake and unstable. Long-term work can easily cause fatigue or physical injury to the user, which is not conducive to the user's health and does not bring a good user experience.

[0006] In addition, such lifting platforms and lifting tables generally only consider the position of the operating table where objects such as computers, books or bookcases are placed, but do not consider the position of the forearms, especially the elbows, on the operating table. As a result, when the user operates for a long time, the forearms, especially the elbows, are suspended in the air, which causes strain on the operator's shoulders and neck. Fig.16 shown. Summary of the invention

[0007] In view of the problems existing in the prior art, the present invention provides a multifunctional bracket, comprising: an operating table, which is convenient for an operator to operate an object placed on the operating table; a height adjustment device, and the operating table is at different heights by being connected to the height adjustment device; and a supporting device, which supports the operating table and makes the angle of the operating table adjustable relative to the horizontal plane, so that the operator is in an upward-looking state when operating the object.

[0008] The multifunctional bracket involved in the present application is composed of components such as an operating table, a height adjustment device and an operating table support device. Different objects are placed on the operating table, and the objects can be electronic devices such as displays, laptops or tablet computers, or books or book racks; an area for placing a mouse and keyboard is also provided on the operating table, so that users can operate different objects on the operating table. The operating table is movably connected to the height adjustment device, and the operating table is adjusted to a suitable height on the height adjustment device according to the height and sitting or standing position of the user. An operating table support device is provided at the bottom of the operating table, and the support device of the operating table can not only support the operating table but also adjust the angle of the operating table based on the horizontal plane, so that the object on the operating table forms a beneficial angle with the user when viewing the object, so that the user is in an upward-looking state, effectively relieving the fatigue of the user's eyes and spine.

[0009] In some embodiments, the height adjustment device includes a column and a connection device with the operating table; the column is provided with a plurality of inclined slots, and the connection device is inserted into the slots to fix the operating table at a predetermined height of the column.

[0010] The height adjustment device is composed of a column and a connecting device, one end of the connecting device is fixedly connected to the operating table, and the other end of the connecting device is movably connected to the column. A plurality of inwardly inclined slots are provided on the column, and the connecting device can be completely engaged with the slots on the column. The connecting device is inserted into the slots on the column so that the connecting device does not shake; the plurality of slots provided on the column are evenly distributed on the column, and the size, angle and depth of each slot are the same, and the connecting device can be inserted into any slot on the column. According to the actual needs of the user, the connecting device is inserted into the slot of the corresponding height, so that the operating table on the connecting device is at the optimal height relative to the user.

[0011] In some embodiments, the multifunctional bracket further includes a holding device disposed on the connecting device, and the holding device drives the connecting device to move along the slot to disengage and engage with the slot, and the operating table is at different heights relative to the column.

[0012] A hand-held holding device is arranged on the top of the connecting device, that is, on the top of the connecting device. The hand-held holding device is tilted outward and fixed to the connecting device by multiple screws; a connecting operating table is fixed to the bottom of the connecting device, and the operating table is fixed to the connecting device by multiple screws, so that the connecting device and the operating table form an integral body. The user can lift the connecting device through the hand-held holding device and drive the operating table at the same time, and freely insert it into all the card slots on the column to make the operating table move up and down. When the user determines the height of the operating table, align the connecting device with the card slot on the column that needs to adjust the height, and directly insert the connecting device into the card slot of the corresponding height to complete the height adjustment of the operating table.

[0013] In some embodiments, the connecting device includes a fixer, which is arranged inside the connecting device, and the fixer includes a card and a baffle, and the card and the baffle form an angle, which is the same as the angle formed by the card slot and the longitudinal direction of the column.

[0014] The connection device in the multifunctional bracket of the present application is provided with a fixer, which is fixed inside the connection device by bolts, and the connection device is inserted into the card slot of the height adjustment device through the fixer to form a mutual engagement. The fixer is composed of a card and a baffle, the card and the baffle intersect at one end, and form an opening at the other end, and the intersection of the card and the baffle forms an angle, and the angle of the angle is the same as the angle in the card slot set on the column, and the card of the fixer can be inserted into the card slot of the column to fix the connection device on the column. The baffle on the fixer is partially fitted with the outer surface of the column, so that the connection device will not shake on the column, and the fixer can only be taken out and detached from the column by moving upward.

[0015] In some embodiments, the column is a single column, or the column includes multiple sections of columns, and the height of the column is increased by splicing the multiple sections of columns.

[0016] The column in the multifunctional bracket can be composed of multiple sections of columns, and the length of each section can be set according to the actual use needs of the user, or it can be composed of a whole section of the column. Card slots are set on all columns, and all the card slots are the same size; buckles are set at both ends of each section of the column, and the buckles are used to connect the two sections of the column to each other, and the card slots of all columns are facing straight ahead; a whole section of the column is selected in this application, and multiple sections of the column can also be spliced ​​according to the actual use needs of the user to increase the length of the column and enhance the actual experience of the user. The splicing method can be a rotatable or snap-fitting method formed by connecting the two sections of the column through an axis, and a spare column can be set behind the column, which can be set according to the actual needs of the user. When the height of the column needs to be increased, a section of the column is directly taken out from the back, and the buckles at both ends are directly spliced ​​to one end of the main column, so that the length of the column can be adjusted more conveniently and quickly. The specifications of the column can be hollow columns or columns of different shapes.

[0017] In some embodiments, the bottom of the column is connected to the base, and the supporting device includes a first supporting frame, one end of which is connected to the bottom of the operating table, and the other end is movably connected to the base to change the angle of the operating table relative to the horizontal plane.

[0018] A base is provided at the bottom of the column, the column and the base are integrated, the column is vertically mounted on the base, and the column and the base are fixed as one by conventional fixed connection methods (such as riveting, threaded connection, welding, etc.). A support device is provided at the bottom of the operating table, and the support device includes a first support frame, which is an integrated bracket, composed of two first support columns and a cross bar connecting the middle sections of the two first support columns and forming an "I" shape. One end of each of the two first support columns is respectively arranged on both sides of the base, and the other end is movably supported on both sides of the bottom of the operating table. The two first support columns in the first support frame can deflect downward up to 180 degrees with the intersection of the base as the center, so as to support operating tables of different angles and heights. The bottoms of the two first support columns can move at different positions on the base, and adjust the angle of the operating table based on the horizontal plane at the same time. Two buckles are also provided at the bottom of the operating table for fixing the two first support columns of the first support frame. When the two first support columns overlap with the surface of the operating table (ie, deflected downward by 180 degrees), the two first support columns of the first support frame will be snapped into their respective corresponding buckles to avoid loosening.

[0019] In some embodiments, positioning holes are provided on both sides of the base, one end of the first support frame is connected to the bottom of the operating table, and the other end can be placed in the positioning holes at different positions.

[0020] A plurality of positioning holes are provided on both sides of the base, and each positioning hole is used to snap into the foot of the first support column on both sides of the support frame to prevent the foot of the first support column from sliding. Each positioning hole is evenly distributed. Each positioning hole between the two sides of the base corresponds to each other, so that the foot of the two first support columns of the first support frame can be in the same corresponding position. The bottom of the two first support columns of the first support frame selects positioning holes at different positions according to the different angles and heights of the operating table, and the angle of the operating table relative to the horizontal plane will be adjusted accordingly when different positioning holes are selected; from the user's visual angle, the smaller the angle of the bottom of the first support frame relative to the connection of the base (that is, the more backward the position of the positioning hole of the first support frame on the base), the greater the angle of the front end of the operating table tilting downward relative to the horizontal plane; the larger the angle of the bottom of the first support frame relative to the connection of the base (that is, the more forward the position of the positioning hole of the first support frame on the base), the smaller the angle of the front end of the operating table tilting downward relative to the horizontal plane. When the height of the operating table is lower, the position of the positioning hole of the first support frame on the base is further back (that is, closer to the column). On the contrary, the position of the positioning hole of the first support frame on the base is further forward (that is, away from the column). The first support frame not only supports the operating table but also is used to adjust the angle of the front end of the operating table (i.e. the end close to the user) relative to the horizontal plane, so that the operator can look up when operating on the operating table, which can effectively protect the user's cervical spine, lumbar spine and eyesight.

[0021] In some embodiments, the multifunctional bracket provided by the present application further includes a second support frame, one end of which is connected to the first support frame, and the other end of which is moved to positioning holes at different positions on the base according to the height of the operating table. When the operating table is very close to the base, and the first support frame cannot support the operating table or adjust the inclination angle of the operating table, the second support frame provides alternative support for the operating table and can be used to adjust the inclination angle of the operating table.

[0022] The second support frame is in the shape of an "open" character, and includes two second support columns, the top ends of which are fixedly connected by a first connecting rod, and the middle parts of the two second support columns are fixedly connected by a second connecting rod. The top ends of the two second support columns are movably connected to the middle sections of the inner sides of the two first support columns of the first support frame. The two second support columns of the second support frame can rotate 180 degrees relative to the first support frame with the connecting rod as the center; the bottom ends of the two support columns of the second support frame can be inserted into the positioning holes on the base. When the first support frame cannot support the operating table at a lower height and adjust its tilt angle, the second support frame is used to support and adjust the tilt angle of the operating table.

[0023] In some embodiments, the height adjustment device is further provided with an auxiliary bracket, one end of which cooperates with the slot on the column to adjust the position of the auxiliary bracket on the column. The auxiliary bracket is provided with an insert, which can be directly inserted into the slot on the column to fix the auxiliary bracket, and the position of the auxiliary bracket on the column can be adjusted according to the user's required height. The insert on the auxiliary bracket is applicable to all the slots on the column, so that the user can adjust the height of the auxiliary bracket by himself.

[0024] In some embodiments, the auxiliary bracket includes a telescopic rod and a device bracket, and a ball head is provided at one end of the telescopic rod, and the ball head cooperates with a ball head seat on the device bracket.

[0025] The auxiliary bracket is composed of a telescopic rod and a device bracket. The telescopic rod can be freely extended and retracted. A plug is set at one end of the telescopic rod, which can be directly inserted into all the card slots on the height adjustment device. A ball head is set at the other end of the telescopic rod. The ball head is used in conjunction with the ball head seat on the device bracket. The ball head seat is set on the back of the device bracket. The device bracket can rotate arbitrarily on the ball head of the telescopic rod through the ball head seat. The user can adjust the angle of the device bracket at will according to the angle he likes. The device bracket can fix smart devices of different sizes such as mobile phones, tablets, etc. and folders. The folders are used to fix paper documents and manuscripts.

[0026] In some embodiments, a limit strip, a limit plate and at least one limit hole are provided on the operating table, and both ends of the limit strip can be inserted into the at least one limit hole to fix the object on the operating table, and both ends of the limit plate can be inserted into the at least one limit hole to prevent the object from sliding on the operating table. The operating table includes an extension extending from the position for placing the object toward the user, which is used to support the forearm and / or elbow of the user who operates the object. When the user is sitting or standing, the elbow will not be left hanging in the air, causing upper limb fatigue.

[0027] In some embodiments, a lighting unit is also provided above the column, and the lighting unit mainly provides appropriate lighting light for the operating table area, so that the user can have a clearer vision when operating on the operating table. It plays a role in protecting eyesight. When the user needs to increase the brightness of the operating table, the lighting unit can be quickly installed on the column, and can be quickly disassembled when not needed.

[0028] The lighting part is in a right-angle shape, with one end being the lighting area and the other end being fixed to the column by a fastening screw. A groove is provided in the area on the lighting part that is fixed to the column, and the fastening screw passes through the groove to fix the lighting part to the column. The lifting or rotating angle of the lighting part can be adjusted by controlling the tightness of the fastening screw. A groove is also provided at the other end of the lighting part, which is connected to the lighting component by a fastening screw. The lighting component can move in the groove at the other end of the lighting part by the fastening screw, so that the lighting component and the lighting part form a telescopic or rotating angle of the lighting component.

[0029] The multifunctional bracket provided by the present application is used in various suitable occasions, such as office desks, workbenches, study tables, etc. Through the cooperation between the operating table and the height adjustment device, the operating table can be raised and lowered on the height adjustment device, and at the same time, when the operating table is supported by the operating table support device, the operating table forms an angle with the horizontal plane. The angle of the operating table can be adjusted according to the operating table support device so that the user is in an upward-looking state, thereby protecting the user's cervical spine, lumbar spine and vision.

In this way, the user drives the connecting device 2 to move along the card slot 12 through the holding device 22 and disengage and engage with the card slot 12. The user aligns the connecting device 2 with the card slot 12 on the column 11 corresponding to the required height, and directly inserts the connecting device 2 into the card slot 12 of the corresponding height to complete the height adjustment of the operating table 3.

[0055] Through the above structure, the user lifts the connection device 2 by the hand-held holding device 22 and drives the operating table 3 at the same time, and freely inserts it into all the slots 12 on the column 11, so that the operating table 3 can be raised and lowered. When the user determines the height of the operating table 3, the connection device 2 is aligned with the slot 12 on the column 11 that needs to be adjusted in height, and the height adjustment of the operating table 3 is completed by directly inserting the connection device 2 into the slot 12 of the corresponding height.

[0056] Please refer to Figures 4 to 7 In an optional implementation of the present embodiment, the connection device 2 includes a fixture 21. The fixture 21 is fixed inside the connection device 2 by bolts 23, and the fixture 21 is provided with a card 211 and a baffle 212. The card 211 and the baffle 212 form an angle, and the angle of the angle is the same as the angle of the inclined slot 12 provided on the column 11. The connection device 2 is inserted into the slot 12 of the column 11 through the card 211 of the fixture 21 and engages with each other, and at the same time, the baffle 212 forms a fitting state with the front of the column 11. The baffle 212 can further prevent the connection device 2 from shaking.

[0057] A fixing device 21 is provided in the connecting device 2, and the fixing device 21 is fixed inside the connecting device 2 by bolts 23. The connecting device 2 is inserted into the card slot 12 of the height adjustment device 1 through the fixing device 21 to form a mutual engagement. The fixing device 21 is composed of a card 211 and a baffle 212. The card 211 and the baffle 212 intersect at one end, and form an opening at the other end. The intersection of the card 211 and the baffle 212 forms an angle, and the angle of the angle is the same as the angle in the card slot 12 provided on the column 11. The card 211 of the fixing device 21 can be inserted into the card slot 12 of the column 11 to fix the connecting device 2 on the column 11. The baffle 212 on the fixing device 21 partially fits with the outer surface of the column 11, so that the connecting device 2 will not shake on the column 11, and the fixing device 21 can only be taken out and separated from the column 11 by moving upward.

Card slots 12 are provided on all columns, and all card slots 12 are the same size.

[0059] When the column 11 is composed of multiple sections of columns, buckles 111 are provided at both ends of each section of the column 11. The buckles are used to connect two sections of the column 11 to each other. The slots 12 of all the columns 11 are facing straight ahead. In this way, multiple sections of columns 11 are spliced ​​according to the user's usage requirements to increase the length of the column 11 and adapt to users of different heights and usage habits. The splicing method can be that the two sections of the column are connected by an axis to form a rotatable or snap-fitting method, and a spare column 11' can be provided behind the column 11. When the height of the column 11 needs to be increased, the spare column 11' is directly taken out from the back, and is directly spliced ​​with one end of the column 11 through the buckles at both ends, so that the height adjustment of the column 11 is more convenient and quick. The column 11 can be a hollow column or a solid column.

[0060] like Fig.11 As shown, a splicing buckle 13 is provided at the bottom of each section of the column 11, and a cylinder 14 is provided at the top of each section of the column 11. The splicing buckle 13 at the bottom of one section of the column 11 is inserted into the cylinder 14 at the top of another section of the column 11, and then the two sections of the column 11 are fixed by an externally added fixing device. There are four screw holes on the fixing device, two in the upper part and two in the lower part. The upper part of the fixing device is fixed to the bottom of the column 11 by two screws, and the lower part of the fixing device is fixed to the top of the column 11 by two screws, so that the two sections of the column 11 form a whole. The splicing buckle 13 is used to connect the two sections of the column 11. The card slots 12 of all the columns 11 are facing straight forward.

[0061] The angle formed by the inclined slot 12 on the column 11 and the longitudinal direction of the column 11 is set in such a way that the card 211 on the holder 21 can be inserted into the slot 12, and the baffle 212 on the holder 21 can be fitted with the front of the column 11 to keep the holder 21 and the slot 12 integrated into one without loosening or shaking, for example, within the range of 30-75 degrees. When the two need to be separated, the holder 21 can be taken out and completely separated from the column 11 by sliding it obliquely upward along the slot 12.

[0062] Two support bars 8 are also provided in the middle of the column 11. One end of each of the two support bars 8 is connected to one side of the column 11, or intersects at an intersection on the column 11. The two support bars 8 thus form a cross, and the bottom of the two support bars 8 is at the same horizontal position as the bottom surface of the bottom plate. A gasket is provided at the other end of each of the two support bars 8, which can effectively prevent the multifunctional bracket from sliding or shaking when placed on the work surface. When not in use, the two support bars 8 can be overlapped and folded, and placed on the back of the column 11, and the two support bars 8 overlap the column 11.

[0063] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 8 , Fig.10 In another optional implementation of the present embodiment, the bottom of the column 11 is connected to the base 6, and the supporting device 44 includes a first supporting frame 4, one end of the first supporting frame 4 is connected to the bottom of the operating table 3, and the other end is movably connected to the base 6 to change the angle of the operating table 3 relative to the horizontal plane.

[0064] A base 6 is provided at the bottom of the column 11. The column 11 and the base 6 are integrated, the column 11 is vertically mounted on the base 6, and the column 11 and the base 6 are fixed as one by a conventional fixing connection method (such as riveting, threaded connection, welding, etc.).

[0065] A supporting device 44 is provided at the bottom of the operating table 3. The supporting device 44 includes a first supporting frame 4, which is an integrated bracket, and is composed of two first supporting columns 41 and a cross bar connecting the middle sections of the two first supporting columns 41 to form an "I" shape. One end of each of the two first supporting columns 41 is respectively arranged on both sides of the base 6, and the other end is movably supported on both sides of the bottom of the operating table 3. The two first supporting columns 41 can be deflected downward by up to 180 degrees with the intersection of the base 6 as the center, so as to support the operating tables 3 of different angles and heights. The bottoms of the two first supporting columns 41 can be movable at different positions on the base 6, and the angle of the operating table 3 relative to the horizontal plane can be adjusted at the same time.

[0066] Two buckles 35 are also provided at the bottom of the operating table 3 for fixing the two first support columns 41 of the first support frame 4. When the two first support columns 41 overlap with the surface of the operating table 3, the two first support columns 41 are snapped into the corresponding buckles 35 to prevent loosening. The two support columns can intersect at the bottom of the operating table 3 and can be deflected downward by 180 degrees, so as to support the operating table 3 at different heights. The bottom ends of the two support columns are connected to the surface of the base 6 and can move on both sides of the surface of the base 6.

[0067] A plurality of positioning holes 61 are provided on both sides of the base 6. Each positioning hole 61 is used to snap into the bottom end of the first support column 41 on both sides of the support frame to prevent the bottom end of the first support column 41 from sliding. Each positioning hole 61 is evenly distributed. Each positioning hole 61 between the two sides of the base 6 corresponds one to one, so that the bottom feet of the two first support columns 41 are at the same corresponding position. The bottom ends of the two first support columns 41 select positioning holes 61 at different positions according to different angles and heights of the operating table 3.

[0068] From the user's visual perspective, the smaller the angle at which the bottom of the first support frame 4 is connected to the base 6 (i.e., the further back the positioning hole 61 of the first support frame 4 is on the base 6), the greater the angle at which the front end of the operating table 3 is tilted downward relative to the horizontal plane; the larger the angle at which the bottom of the first support frame 4 is connected to the base 6 (i.e., the further forward the positioning hole 61 of the first support frame 4 is on the base 6), the smaller the angle at which the front end of the operating table 3 is tilted downward relative to the horizontal plane.

[0069] The lower the height of the operating table 3 is, the more the first support frame 4 is positioned on the base 6 to the rear (i.e., closer to the column 11) to the position of the positioning hole 61. On the contrary, the more the first support frame 4 is positioned on the base 6 to the front (i.e., farther from the column 11) to the position of the positioning hole 61. The first support frame 4 can not only support the operating table 3 but also be used to adjust the angle of the front end of the operating table 3 (i.e., the end close to the user) relative to the horizontal plane, so that the operator is in an upward-looking state when operating on the operating table 3, which can effectively protect the user's cervical spine, lumbar spine and vision.

[0070] like Figure 2 , Figure 8As shown, the multifunctional bracket also includes a second support frame 5, one end of which is connected to the first support frame 4, and the other end is moved to the positioning hole 61 at different positions according to the height of the operating table 3. When the first support frame 4 cannot support the operating table 3 (that is, the smaller the height of the operating table 3 is or the closer the distance between the operating table 3 and the base 6 is), the second support frame 5 is used for support. The second support frame 5 is roughly in the shape of an "open" character. The second support frame 5 includes two second support columns 51, and the top of the second support frame 5 is fixed to the middle section of the inner side of the two first support columns 41 of the first support frame 4. The two ends of the second support frame 5 are movably connected to the inner side of the two edges of the first support frame 4, and the second support frame 5 can be centered on the support rod, and the second support column 51 of the second support frame 5 can be rotated 180 degrees. The bottom ends of the two support columns 51 of the second support frame 5 can be inserted into the positioning hole 61 on the base 6. When the first support frame 4 cannot adjust the low height and low angle of the operating table 3, the second support frame 5 is used for support adjustment to adjust the angle of the front end of the operating table 3 relative to the horizontal plane.

[0071] The multifunctional bracket base 6 provided in the present application is suitable for various types of workbenches. The base 6 occupies a small area of ​​the workbench, and the support columns and support bars 8 support the multifunctional bracket, which can make the multifunctional bracket more stable on the workbench and less likely to shake.
