Description

Technical Field

[0001] This application relates to a support device, and more particularly to a support device with a quick-release function. Background Technology

[0002] Patent CN212617111U discloses an internally recessed double-rotation mechanism and a screen containing the mechanism, which integrates rotation and tilting / retracting functions into one unit and is mounted on a support body. It includes a screen, a fixing component, a pivoting component, and a plastic cover. The fixing component has a circular cavity on one side and is connected to the screen. The pivoting component includes a movable disk and a pivoting block. The pivoting block is pivotally connected to the movable disk. The movable disk is immersed in the circular cavity, and the pivoting block protrudes outward and is exposed outside the circular cavity. The plastic cover is used to cover the circular cavity and has a body, an elastic hook, and an elastic element. The elastic hook is disposed on the body, and the elastic element passes through the elastic hook. The support body includes a column and a base for mounting the column.

[0003] While this design effectively reduces the size of the pivoting components, the packaging volume is still quite large because only the chassis and the uprights are separated at the time of shipment (to be assembled by the user). The fixing and pivoting components are already assembled on the uprights of the bracket body, which prevents the packaging cost from being effectively reduced. Utility Model Content

[0004] This application provides a support device for supporting a display on a work surface. The support device includes: a support frame disposed on the work surface, comprising a column and an opening, the column extending substantially along a direction of gravity, and the opening formed in the column; a trolley slidably disposed within the column, and comprising an assembly groove communicating with the opening; a support unit comprising a support member and a protruding neck, the support member supporting the display, and the protruding neck pivotally connected to the support member; a main insert disposed on one of the trolley and the protruding neck, and detachably disposed in the assembly groove along an axis, and comprising a first snap-fit ​​portion; and a certain force spring. A spring seat, disposed on one of the trolley and the protruding neck, is movable between a first position and a second position along the direction of gravity, and includes a second latching portion; wherein, when the main plug is accommodated in the assembly slot and the constant force spring seat is located in the first position, the first latching portion and the second latching portion latch each other, and the main plug cannot detach from the constant force spring seat, thereby connecting the support unit to the trolley, and the protruding neck extends outward from the opening; when the main plug is accommodated in the assembly slot and the constant force spring seat is located in the second position, the first latching portion disengages from the second latching portion, and the support unit can detach from the trolley.

[0005] As described above, the constant force spring seat also includes an operating part, the second latching part is formed in the operating part and faces the assembly groove, the operating part extends along the axis and partially protrudes from the opening, and is constantly maintained in the first position when not subjected to external force.

[0006] As described above, the assembly slot has an abutment surface. In the first position, the operating part is away from the abutment surface, and in the second position, the operating part is adjacent to the abutment surface.

[0007] As described above, the constant force spring seat also includes an extension portion disposed in the assembly groove. The operating part extends outward from the extension portion. When an external force is applied to the operating part, the operating part can change from the first position to the second position with the extension portion as the fulcrum. When the external force is removed, the operating part springs back to the first position.

[0008] As described above, the trolley also includes a body and a receiving groove. The assembly groove and the receiving groove are defined by the body and are arranged vertically and interconnected along the direction of gravity. The constant force spring seat also includes a main body portion, which is received in the receiving groove. The extension portion extends outward from the main body portion, and the operating portion is spaced apart from the main body portion.

[0009] As described above, the main plug-in also includes a block and an elastic sleeve. The elastic sleeve is fitted onto the block and has two grooves and a positioning protrusion. The main body has two protrusions and a positioning hole. The protrusions slide in the grooves and the positioning protrusion is accommodated in the positioning hole. The first snap-fit ​​portion extends outward from the block and is exposed in the elastic sleeve.

[0010] As described above, the extension has a first plate and a second plate. The first plate extends outward from the main body and connects to one end of the operating part. The second plate is perpendicular to the first plate and is disposed between the operating part and the main body.

[0011] As mentioned above, the support device, the constant force spring seat and the elastic sleeve are made of polyoxymethylene (POM).

[0012] The aforementioned support device also includes an elastic element, the two ends of which abut against the constant force spring seat and the trolley, respectively, to constantly provide an elastic force that keeps the constant force spring seat in the first position.

[0013] The aforementioned support device also includes at least one constant-force spring, which is connected to the trolley and the column respectively.

[0014] The aforementioned support device also includes two slide rails, which are disposed between the column and the trolley, allowing the trolley to slide back and forth along the direction of gravity.

[0015] In summary, the support device of this application requires no additional control of the operating unit during the assembly of the main plug-in to the constant force spring seat. The assembly of the main plug-in and the constant force spring seat can be completed simply by utilizing the latches between the first and second latches and the automatic reset of the operating unit. The assembly method is simple and convenient, and the relevant quick-release structures are all concealed within the trolley and not excessively exposed, enhancing the overall aesthetics. Furthermore, since the load-bearing unit can be detached from the trolley and support frame, they can be shipped separately, effectively reducing packaging volume and cost.

[0023] Explanation of main component symbols Detailed Implementation

[0024] Please see Figure 1 , Figure 2 and Figure 3 The support device 1000 of this application is used to support a display 2000 on a working surface 3000. The support device 1000 includes a support frame 1, a trolley 2, a bearing unit 3, a main plug 4, a constant force spring seat 5, and an elastic element 6 (see reference). Figure 5The support frame 1 is mounted on the work surface 3000 (e.g., a desktop). A trolley 2 is mounted on the support frame 1; a load-bearing unit 3 is detachably mounted on the trolley 2 via a main insert 4 and a constant spring seat 5, and is used to support the display 2000; the main insert 4 is mounted on the load-bearing unit 3, and the constant spring seat 5 is mounted on the trolley 2 and is removably connected to the main insert 4. An elastic element 6 is located between the trolley 2 and the constant spring seat 5. Constant springs 7 connect the trolley 2 and the support frame 1. Slide rails 8 are located between the support frame 1 and the trolley 2. The structure of each component and their interconnections will be described in detail below. Some diagrams illustrate a gravity direction G and an axis X, with axis X approximately perpendicular to the gravity direction G.

[0025] The support frame 1 includes a base 11, a column 12, and an opening 13. The base 11 is generally a polygonal plate placed on the working surface 3000, but is not limited thereto; it can also be used to clamp a tabletop or be locked to a wall. The column 12 includes a shell 121 and a hollow structure 122. The shell 121 covers the outer periphery of the hollow structure 122, which extends substantially along the direction of gravity G, with one end attached to the base 11. The opening 13 is formed in the shell 121. In this embodiment, the column 12 extends at a slight inclination to the working surface 3000; in other embodiments, the column 12 may extend perpendicular to the working surface 3000, and this is not a limitation.

[0026] The trolley 2 is slidably disposed within the hollow structure 122 of the column 12, and includes a body 21, an assembly slot 22, a receiving slot 23, and a receiving slot 24. The body 21 is generally cuboid in shape and has two protrusions 211 and a positioning hole 212. The protrusions 211 extend approximately along the axis X at intervals and are located within the assembly slot 22. The positioning hole 212 is located at one end of the protrusions 211 and communicates with the assembly slot 22. The receiving slot 24, the assembly slot 22, and the receiving slot 23 are defined by the body 21 and are arranged sequentially vertically along the direction of gravity G. The assembly slot 22 and the receiving slot 23 are interconnected, and the assembly slot 22 communicates with the opening 13 and has an abutment surface 221. The supporting unit 3 includes a supporting member 31 and a protruding neck 32. The supporting member 31 is pivotally connected to one end of the protruding neck 32 and is used to support the display 2000.

[0027] Please also refer to Figure 4The main plug-in 4 includes a block 41, a first snap-fit ​​portion 42, and an elastic sleeve 43. The block 41 is fixed to the other end of the protruding neck 32. The first snap-fit ​​portion 42 extends outward from the bottom side of the block 41. The elastic sleeve 43 is fitted onto the block 41 and exposes the first snap-fit ​​portion 42, and has two grooves 431 and a positioning protrusion 432. The grooves 431 are respectively for the protrusions 211 to slide on, and the positioning protrusion 432 can be accommodated in the positioning hole 212. In this embodiment, the elastic sleeve 43 is made of polyoxymethylene (POM) material, and the thickness of the elastic sleeve 43 can be used to adjust the tightness of the main plug-in 4 when it is inserted into the assembly slot 22.

[0028] Please also refer to Figure 5 and Figure 6 A constant-force spring seat 5 is disposed on the trolley 2 and includes a main body 51, an extension 52, an operating part 53, and a second latching part 54. The main body 51 is fitted into the receiving groove 23. The extension 52 is disposed in the assembly groove 22 and has a first plate 521 and a second plate 522 extending outward from the main body 51 and approximately perpendicular to it, i.e., the first plate 521 and the second plate 522 have a T-shaped cross-section. The operating part 53 extends outward from the extension 52 approximately along the axis X and is spaced apart from the main body 51, such that the first plate 521 is connected to one end of the operating part 53, the second plate 522 is disposed between the operating part 53 and the main body 51, and the other end of the operating part 53 is a free end with a protruding opening 13. A positioning post 531 is provided on the bottom surface of the operating part 53. The second latching part 54 is formed on the top surface of the operating part 53 and faces the assembly groove 22, and corresponds to the positioning post 531. In this embodiment, the constant force spring seat 5 is made of polyoxymethylene (POM).

[0029] One end of the elastic element 6 abuts against the contact surface 221 of the trolley 2, and the other end is sleeved on the positioning post 531 of the operating part 53, and constantly provides an elastic force. In this embodiment, the elastic element 6 is a compression spring.

[0030] The constant force springs 7 are respectively connected to the trolley 2 and the column 12, and each has a connected cylindrical part 71 and a movable end 72. The cylindrical part 71 of one of the constant force springs 7 is provided in the receiving groove 24, and its corresponding movable end 72 extends out from the receiving groove 24 and is fixed to the hollow structure 122. The cylindrical part 71 of the other constant force spring 7 is provided in the main body 51, and its corresponding movable end 72 extends out from the main body 51 and is fixed to the hollow structure 122, thereby the constant force spring 7 can constantly provide an elastic force.

[0031] The slide rails 8 are respectively disposed on opposite sides of the hollow structure 122 and fixed to the opposite sides of the body 21 of the trolley 2, so that the slide rails 8 are located between the hollow structure 122 and the body 21, thereby allowing the trolley 2 to slide back and forth along the direction of gravity G. In this embodiment, the slide rail 8 may be a three-section slide rail.

[0032] The following describes the component relationship between the main plug-in 4 and the constant force spring seat 5, including their mating connection and mutual removal. The operating part 53 of the constant force spring seat 5 can be in a first position along the direction of gravity G ( Figure 6 and Figure 7 ) and a second position ( Figure 8 Transformation between ( ). For example, Figure 6 and Figure 7 As shown, when the main plug 4 is gradually inserted into the assembly slot 22 along the axis X through the opening 13, the protrusions 211 slide on the grooves 431 respectively, the first latching part 42 slides on the upper surface of the second latching part 54 and presses down the second latching part 54, so that the operating part 53 changes from the first position to the second position with the end of the second plate 522 of the extension part 52 as the fulcrum and approaches the abutment surface 221, while compressing the elastic member 6. Figure 7 As shown, when the main plug 4 is fully inserted into the assembly slot 22 and the positioning protrusion 432 is accommodated in the positioning hole 212, the elastic force of the elastic member 6 causes the operating part 53 to bounce back from the second position to the first position and move away from the contact surface 221, so that the first latching part 42 and the second latching part 54 change from being misaligned to being latched, and the main plug 4 cannot be disengaged from the constant force spring seat 5, thereby connecting the bearing unit 3 with the trolley 2, and the protruding neck 32 extends outward from the opening 13.

[0033] like Figure 8 As shown, to detach the support unit 3 from the trolley 2, an external force F is applied to the operating part 53 along the direction of gravity G. This causes the operating part 53 to shift from the first position to the second position, using the end of the second plate 522 of the extension 52 as a fulcrum, and to approach the abutment surface 221. At the same time, the elastic member 6 is compressed. At this time, the first latching part 42 and the second latching part 54 disengage from each other, and the support unit 3 can detach from the trolley 2 along the axis X. When the external force F is removed, the operating part 53 can rebound from the second position to the first position and move away from the abutment surface 221 by the elastic force of the elastic member 6.

[0034] The above embodiment uses the elastic force provided by the elastic element 6 to keep the operating part 53 constantly in the first position. In other embodiments, the elastic element 6 may be omitted, and the rigidity of the operating part 53 itself may be used to keep it constantly in the first position without being subjected to external force.

[0035] Furthermore, the length of the second plate 522 can be adjusted to determine the fulcrum of the operating part 53 when it changes between the first and second positions, providing the user with different operating feel. For example, when the second plate 522 has a longer length, the lever arm of the operating part 53 is shorter and the overall rigidity is stronger; conversely, when the second plate 522 has a shorter length, the lever arm of the operating part 53 is longer and the overall rigidity is weaker. In other embodiments, the second plate 522 can be omitted, and the overall rigidity can be determined solely by the thickness of the operating part 53 itself.

[0036] In summary, the support device of this application requires no additional control of the operating unit during the assembly of the main plug-in to the constant force spring seat. The assembly of the main plug-in and the constant force spring seat can be completed simply by utilizing the latches between the first and second latches and the automatic reset of the operating unit. The assembly method is simple and convenient, and the relevant quick-release structures are all concealed within the trolley and not excessively exposed, enhancing the overall aesthetics. Furthermore, since the load-bearing unit can be detached from the trolley and support frame, they can be shipped separately, effectively reducing packaging volume and cost.
