Description

Display transport carts and display transport methods

[0001] The present invention relates to a display transport cart and a method for transporting a display, and more particularly, to a display transport cart and a method for transporting a display that can be used when transporting a display such as a large TV using an elevator.

[0002] As large displays, especially large-screen TVs, become more widespread, the need for safe and efficient transportation methods is growing. Large displays are generally at greater risk of damage during transportation due to their size and weight. Transporting them using elevators poses particular challenges, particularly in confined spaces, where damage to the device and difficulty in securing it are common issues.

[0003] Previously, transporting large displays primarily involved simple carts, handcarts, or manual labor. A cart is a wheeled device used to transport objects. For example, using a standard cart not designed for transporting large TVs increases the risk of the TV becoming unstable or being damaged by impact.

[0004] Large TVs, in particular, are often too large to fit in elevators in their boxed form, leading to purchases being abandoned in high-rise buildings. Transporting them unpackaged increases the risk of damage, and transporting them up stairs is labor-intensive and inefficient.

[0005] Furthermore, even when elevators are available, manually transporting large displays is time-consuming and carries a high risk of damage during transport. Conventional transport carts lack the ability to safely secure and protect displays in such situations, making them vulnerable to vibration and shock during transport.

[0006] These issues have led to a growing need for safe transportation of large displays to high-rise buildings. As existing transport carts fail to meet these demands, a new type of cart capable of stably securing displays and absorbing shocks has become necessary.

[0007] The purpose of the present invention is to provide a transport cart that can safely transport a large display by preventing damage that may occur during transport.

[0008] In addition, the present invention aims to provide a transport vehicle and transport method that shortens transport time and improves work efficiency when transporting a large display using an elevator.

[0009] The problems to be solved by the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0010] A display transport cart according to the present invention may include a fixed frame (100) to which a display is fixed, and a moving means (200) for moving the fixed frame.

[0014] The above angle adjustment device (240) may include an angle adjustment rod (241) whose end is fixed to a support frame and a holder (242) whose end is fixed to a support frame and through which the angle adjustment rod passes.

[0015] The above fixed frame includes a horizontally fixed hanger bar (110), and the above mounting portion (212) may include a hook-shaped mounting member that supports the lower portion of the above hanger bar (110).

[0016] The above fixed frame (100) may include a shield (120) in the form of a cover connected to the top and bottom to protect the edges of the display.

[0017] The above shield can be connected to the fixed frame so as to be rotatable forward and backward.

[0018] The above shield can move linearly for a certain distance in the longitudinal direction of the above fixed frame.

[0019] The above fixed frame may include a bracket plate (130) having a plurality of VESA holes into which VESA protrusions on the rear of the display are inserted.

[0020] The above fixed frame may include at least one handle attached to the side.

[0021] The first and second wheels may include omni-wheels, which are omnidirectional wheels.

[0022] A display transport method according to the present invention may include a step of combining the rear surface of a display with a bracket plate of a fixed frame, a step of adjusting a shield of the fixed frame to protect an edge of the display, a step of mounting the fixed frame on a mounting frame of a moving means, a step of adjusting or fixing an angle between the mounting frame and a support frame, a step of adjusting the height of the mounting frame, and a step of transporting the display using wheels of the moving means.

[0023] According to one embodiment of the present invention, damage that may occur during transportation can be effectively prevented by safely securing a large display to a transport cart.

[0039] Hereinafter, the configuration of a display transport cart according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. FIG. 1 is a perspective view illustrating a display transport cart according to an embodiment of the present invention. FIG. 2 is a drawing for explaining the configuration of a display transport cart according to an embodiment of the present invention.

[0040] A display transport cart (10) may include a fixed frame (100) and a moving means (200).

[0041] The fixed frame (100) is a structure for stably fixing a display and may include a bracket plate (130) attached to the rear of the display. The bracket plate (130) is formed with a plurality of VESA holes (not shown) that can be combined with the VESA protrusions of the display, thereby fixing displays of various sizes.

[0042] The fixed frame (100) may also include a shield (120) to protect the edges of the display. The shield (120) is positioned at the top and bottom of the display, and serves to protect the display from damage during movement. The shield (120) can rotate forward and backward, and its position can be adjusted to fit the length of the display as needed. The fixed frame will be described in detail later with reference to FIG. 5.

[0043] The means of transportation (200) includes components designed to support and transport the fixed frame (100). The means of transportation (200) may include a mounting frame (210), a support frame (220), wheels (230), etc. The mounting frame (210) and the support frame (220) may be erected in a ladder shape with one end fixed, and wheels may be mounted at the bottom of each frame to facilitate smooth movement of the cart.

[0044] The mounting frame (210) supports the fixed frame (100) and may include a mounting member (212) that can stably fix the fixed frame. The mounting member (212) is a hook-shaped member that supports the hanger bar (110) of the fixed frame (100) to fix the display so that it does not shake or move during transportation. The moving means will be described later with reference to FIGS. 3 and 4.

[0045] The hanger bar (110) is located inside the fixed frame (100) and can stably mount the fixed frame (100) on the mounting portion (212) of the moving means (200). The hanger bar (110) can be manufactured from a material having sufficient rigidity and durability to support the weight of the display, and can be designed in various lengths and shapes depending on the size and weight of the display. As can be seen in FIGS. 1 and 2, the hanger bar (110) provides a structure that allows the fixed frame (100) to be easily mounted by simply hanging on the mounting portion (212).

[0046] Hereinafter, with reference to FIGS. 3 and 4, a moving means of a display transport cart according to an embodiment of the present invention will be described in detail. FIG. 3 is a perspective view illustrating a moving means of a display transport cart according to an embodiment of the present invention, and FIG. 4 is a rear perspective view of the moving means as viewed from the rear.

[0047] The moving means (200) of the display transport cart (10) of the present invention may include various components for stably supporting the display and facilitating movement. The moving means (200) may be configured around a support frame (210) and a supporting frame (220).

[0048] The support frame (210) is a structure that stably supports the fixed frame (100). The support frame (210) may include a height adjustment device (211) and a support portion (212).

[0049] The support member (212) serves to support the fixed frame (100) and may be designed to effectively distribute the weight of the display and provide stable support. Furthermore, it may also securely secure the fixed frame (100) to prevent the display from shaking or moving during transport. To this end, the support member (212) may be manufactured from a material with sufficient rigidity and durability to withstand the size and weight of the display.

[0050] Referring to FIG. 3, a mounting portion (212) formed of a hook-shaped mounting member facing the front of the mounting frame (210) is illustrated. As described above with reference to FIGS. 1 and 2, the mounting portion (212) may be designed so that the fixed frame (100) is stably mounted on the front of the mounting frame (210). This form is a structure that supports the lower portion of the hanger bar (110) of the fixed frame (100), thereby allowing the fixed frame (100) to be conveniently mounted. The form illustrated in FIG. 3 is merely a single example, and any configuration capable of mounting the fixed frame (100) may be implemented in various ways.

[0051] The mounting frame (210) may also include a height adjustment device (211) that can adjust the height as needed. The height adjustment device (211) may be installed to adjust the height of the mounting portion (212), and maintains an appropriate height so that the display equipped with the fixed frame (100) does not drag on the floor or touch the ceiling. The height adjustment device (211) may be installed on the mounting frame (210), and its type and location are not limited as a configuration for adjusting the height of the display to be transported.

[0052] For example, a height adjustment device (211) according to one embodiment of the present invention is located at the lower end of the mounting frame (210), and can precisely adjust the height of the mounting portion (212) through a lift mechanism disposed between the first wheel (231) and the lower end of the mounting frame (210).

[0053] This lift mechanism can typically consist of a precision height-adjustable device, such as a screw jack, hydraulic cylinder, or gear drive, which can automatically balance itself according to the weight of the display and maintain the optimal height of the display in various transport situations.

[0054] Additionally, the height adjustment device (211) may be designed to be either electrically or manually operated for user convenience, and may be controlled via a control lever or button located on the side of the mounting frame (210) for ease of operation. This design allows for rapid height adjustment of the display to suit the work environment, and ensures safe transportation by optimizing the gap between the top and bottom of the display when entering the elevator.

[0055] Meanwhile, referring to FIG. 4, the support frame (220) is connected to the stand frame (210) on one side and is positioned connected to the rear of the stand frame (210) to effectively distribute the weight of the display and maintain the overall balance.

[0056] The support frame (220) has a structure that can rotate backwards and is designed to adjust the angle with respect to the stand frame (210). This allows the display to be positioned at various angles, which is advantageous in adjusting the height or center of gravity of the display. The support frame (220) is connected to the stand frame (210) through a hinge structure, and this hinge structure allows the support frame (220) to rotate and adjust the angle it forms with respect to the stand frame (210).

[0057] In particular, the support frame (220) is connected to an angle adjustment device (240) to adjust the angle. The angle adjustment device (240) provides a mechanism that allows the user to adjust the angle between the support frame (220) and the mounting frame (210) as desired or fix it at a specific angle.

[0058] The angle adjustment device (240) may be composed of an angle adjustment rod (241) fixed to a mounting frame (210) and a holder (242) fixed to the rod (241) on a support frame (220). The angle adjustment rod (241) connects the support frame (220) and the mounting frame (210), and the rod may pass through the holder (242) to rotate or be fixed at a specific angle. This structure can increase stability during display transportation and prevent accidents caused by shaking or changes in the center of gravity during movement.

[0059] The angle-adjusting rod (241) can be manufactured from various materials and shapes, including a cylindrical metal rod or a rod with a square cross-section. A cylindrical rod can minimize friction during rotation, while a rod with a square cross-section can further enhance stability at a specific angle. The rod can include a length-adjusting function as needed, allowing the user to adjust the display's position at various angles.

[0060] The holder (242) is a component that stably supports the load and enables rotation or fixation of the load. The holder can generally be designed as a clamp or sleeve type with an internal surface machined to fit the shape of the load. The clamp-type holder allows the load to be fixed or rotated by tightening or loosening, while the sleeve-type holder allows the load to rotate freely within a certain range. In addition, the holder may include a locking mechanism that can fix the position of the load at a specific angle, which can be implemented manually or automatically.

[0061] In addition, a first wheel (231) and a second wheel (232) may be mounted on the lower portions of the mounting frame (210) and the support frame (220), respectively. At this time, the first wheel and the second wheel may be composed of multiple wheels. These wheels are components designed to increase the mobility of the display transport cart (10), and each wheel may be composed of an omni-wheel. The omni-wheel includes a plurality of rollers arranged at regular intervals along the circumference of the wheel, and these rollers are arranged perpendicular to the rotational direction of the wheel.

[0062] The first wheel (231) and the second wheel (232) are configured as omni-wheels, enabling the cart to move forward and backward, as well as left and right, and rotate. The structural characteristic of the omni-wheel is that each wheel can rotate in a specific direction while the rollers can rotate vertically, allowing the cart to move in various directions. As a result, the display transport cart (10) can easily change direction and transport displays even in narrow spaces.

[0063] The rollers of an omniwheel are typically made of high-strength plastic or metal and may be designed with bearings to reduce friction during rotation. This arrangement of rollers reduces surface resistance and allows the carriage to move smoothly, especially in confined spaces such as elevators and narrow hallways. Omniwheels also distribute the load, maintaining carriage stability and helping prevent damage to displays.

[0064] The first wheel (231) and second wheel (232) are mounted on the front and rear of the cart, respectively, and work together to maintain the display's balance while allowing it to move in various directions. This arrangement supports directional changes while stabilizing the cart's center of gravity, allowing the operator to move the display with minimal effort.

[0065] Through this configuration, the display transport cart (10) of the present invention can be designed to safely and efficiently transport large displays. This design of the transport vehicle ensures the stability of the display while also allowing operators to flexibly respond to various situations.

[0066]

[0067] Hereinafter, a fixed frame (100) of a display transport cart according to one embodiment of the present invention will be described in detail with reference to FIG. 5. FIG. 5 is a perspective view illustrating a fixed frame (100) of a display transport cart according to one embodiment of the present invention.

[0068] The fixed frame (100) may include a hanger bar (110), a shield (120a, 120b), a bracket plate (130a, 130b), a handle (140), etc.

[0069] The hanger bar (110) is located inside the fixed frame (100) and can be fixed horizontally. The hanger bar (110) enables the fixed frame to be stably fixed to the mounting portion (212) of the moving means (200).

[0070] The hanger bar (110) is made of a rigid material capable of sufficiently supporting the weight of the display, and helps the fixed frame (100) to be firmly mounted on the cart. As described in FIGS. 1 and 2 , the hanger bar (110) can provide a structure that allows the fixed frame (100) to be easily mounted by simply hanging it on the mounting portion (212).

[0071] The fixed frame (100) may include shields (120a, 120b) that protect the top and bottom of the display. The shields (120a, 120b) are respectively positioned at the top and bottom of the fixed frame (100) and are located along the edges of the display.

[0072] The shield (120a, 120b) has a structure that can rotate forward and backward, and can be connected to the fixed frame (100) via a hinge or pivot mechanism. This rotational structure allows the shield (120a, 120b) to tilt or unfold toward the front or back of the display, and can be set to various angles as needed. When the display is fixed, the shield is tilted backward, and after the display is fixed, it can be rotated forward to wrap around the edge of the display.

[0073] The shield (120a, 120b) can also be adjusted longitudinally to match the length of the display. To this end, the shield may include a sliding mechanism that can move longitudinally along the fixed frame. This sliding mechanism allows the shield (120a, 120b) to move linearly within the fixed frame (100) for a predetermined distance, thereby allowing it to be adjusted to match the size of the display. This sliding mechanism allows the shield's position to be adjusted according to the size of the display, thereby safely protecting all edges of the display.

[0074] The shield (120a, 120b) surrounds the display in all directions and can effectively protect the display from shocks, scratches, or drops that may occur during movement. The shield (120a, 120b) can be primarily made of high-strength metal or durable synthetic material, and can be appropriately lubricated to ensure smooth sliding and rotational functions.

[0075] Additionally, the surface of the shield (120a, 120b) is finished flat, and a material that can act as a buffer can be attached to the part that comes into contact with the surface of the display.

[0076] In addition, the fixed frame (100) is located on the rear side of the display and includes a bracket plate (130a, 130b) that can firmly mount the display on the moving means (200). The bracket plate (130a, 130b) has a plurality of VESA holes formed that can be combined with the VESA protrusions on the rear side of the display, so that displays of various sizes can be fixed.

[0077] The side of the fixed frame (100) may include a handle (140) for the convenience of the operator during transport. The handle (140) is designed to enable the operator to easily operate it when mounting or detaching the fixed frame from or to a moving vehicle (200). The handle (140) may be positioned on both sides of the fixed frame (100) to enable the display to be safely transported.

[0078] A display transport cart configured as described above can stably secure and protect a display while allowing for smooth transport via a transport vehicle (200). Specifically, when transporting a display using an elevator according to an embodiment of the present invention, the display can be safely positioned within the elevator by appropriately adjusting the angle and height of the mounting frame (210) and the support frame (220). Consequently, even large displays can be easily transported via the elevator, while minimizing the risk of damage that may occur during transport.

[0079] Figure 6 is a flowchart illustrating a display transport method according to one embodiment of the present invention.

[0080] First, the worker spreads out the fixed frame (100) on the floor and positions the display to be transported so that its rear side faces the fixed frame. At this time, the VESA protrusions on the rear of the display are adjusted so that they are accurately inserted into appropriate positions among the multiple VESA holes formed in the bracket plates (130a, 130b) of the fixed frame (100), thereby stably positioning the display.

[0081] Next, the rear of the display is firmly fixed to the bracket plate (130a, 130b) of the fixed frame (100) so that it does not move during transportation (S101).

[0082] After the display is accurately fixed to the fixed frame (100), the shields (120a, 120b) located at the top and bottom of the fixed frame (100) are adjusted to protect the edges of the display (S102). At this time, the shield may be set to be tilted backwards in the initial state and then rotated forward to wrap around the edges of the display. In addition, the shield may be adjusted to a position where it wraps around the edges according to the size of the display by moving linearly for a certain distance in the longitudinal direction of the fixed frame (100). By adjusting the shield to protect the display, damage and breakage that may occur during movement can be prevented.

[0083] After the display is completely fixed to the fixed frame (100), the fixed frame (100) is lifted and placed on the mounting frame (210) of the moving means (200) (S103). At this time, the moving means (200) may be in an upright state, and the worker can easily place it by simply placing the hanger bar (110) of the fixed frame (100) on the mounting part (212) of the moving means (200).

[0084] Next, the angle between the mounting frame (210) and the support frame (220) of the mobile device (200) is adjusted and fixed (S104). At this stage, it may be necessary to find and fix an appropriate angle depending on the needs related to the center of gravity, stability, or display height. This angle can be adjusted and fixed using an angle adjustment device (240), and the configuration of the angle adjustment device can be implemented in various ways as previously described.

[0085] Additionally, the height of the stand frame (210) can be adjusted as needed (S105). In one embodiment of the present invention, the height of the frame can be adjusted using a height adjustment device (211) located at the bottom of the stand frame (210). This function can be utilized when an appropriate height needs to be set depending on the size of the display.

[0086] After completing the display mounting and all adjustment steps, the display is transported by pushing the transport vehicle (200) using the wheels (230) (S106). By using the transport cart according to one embodiment of the present invention, work can be easily done outdoors, and the transport time can be significantly shortened, especially when transporting using an elevator.

[0087] It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

[0088] The above detailed description should not be construed as limiting in any respect and should be considered illustrative only. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are intended to be included within the scope of the present invention.
