Description

Technology Field

[0001] The present invention relates to a pallet caster movement adjustment module for transporting goods, and more specifically, to a pallet caster movement adjustment module for transporting goods that can selectively restrict or allow the rotation and movement of a caster equipped on a pallet for transporting goods.

[0002] In particular, the present invention relates to a pallet caster movement adjustment module for transporting goods, wherein the vertical frame and the connecting frame perform a lifting motion in conjunction with the operation of a toggle clamp, and a stop module that contacts or separates from the caster module accordingly operates selectively, thereby enabling the pallet to be easily switched between a moving state and a fixed state. Background Technology

[0003] In general, material transport pallets are widely used in logistics sites and production lines to efficiently transport various goods. These pallets are equipped with multiple casters on the bottom, designed to allow workers to easily move goods with minimal effort.

[0004] However, while pallets equipped with casters as described above are easy to move, problems may arise where the pallet moves unintentionally during operation. In particular, in slanted working environments or when subjected to external impacts, pallets may move arbitrarily, posing a risk to worker safety or causing loaded goods to fall or be damaged.

[0006] To address this, conventional methods have been proposed to add a brake function to the caster itself or to secure the pallet to the ground using a separate fixing device. However, in the case of a caster-integrated brake structure, there is the inconvenience of having to operate each caster individually, and there is a problem of brake performance deteriorating with repeated use. In addition, when using a separate fixing device, the structure becomes complex and the installation space increases, which limits the versatility of the pallet.

[0007] Furthermore, most conventional fastening devices rely on simple support or friction, making it difficult to secure sufficient fastening force and posing a problem where users find it difficult to quickly fasten and release. In particular, when large pallets or heavy loads are loaded, the fastening device does not operate smoothly, resulting in reduced work efficiency.

[0009] Meanwhile, some technologies propose operating the fixing device using lever or link structures; however, these structures also involve numerous components and complex assembly, leading to increased manufacturing costs and room for improvement in terms of durability. Furthermore, since they are limited to merely supporting the entire pallet without directly controlling the rotation of the casters, achieving more stable movement control is currently difficult.

[0011] Therefore, there is a need to develop a new type of pallet caster movement control technology for material transport that is implemented with a simple structure, allows for selective control of pallet movement and fixation with a single operation, and ensures a more stable fixed state by directly restricting the rotation of the caster.

[0013] The present invention is proposed to solve the above-mentioned problems and aims to provide a pallet caster movement adjustment module for transporting goods that allows for the selective restriction or permission of rotation of a caster equipped on a pallet for transporting goods, thereby enabling the pallet to easily switch between a moving state and a fixed state.

[0015] In addition, the present invention aims to provide a pallet caster movement adjustment module for transporting goods that improves user convenience and increases work efficiency by enabling simultaneous control of rotational limits for multiple casters with only one toggle clamp operation.

[0017] In addition, the present invention aims to provide a pallet caster movement adjustment module for transporting goods that provides a more reliable and stable caster rotation limiting function by implementing a lifting operation through an interlocking structure of a vertical frame and a connecting frame, and configuring the stop module to directly contact or be separated from the caster module accordingly.

[0019] In addition, the present invention aims to provide a pallet caster movement adjustment module for transporting goods, which is composed of a relatively simple mechanical structure, making it easy to manufacture and assemble, has excellent durability, and is easy to maintain.

[0021] Furthermore, the present invention aims to provide a pallet caster movement adjustment module for transporting goods that ensures economic efficiency by enabling operation without a separate complex control device or additional power source, and improves versatility so that it can be applied to various types of pallets for transporting goods. means of solving the problem

[0022] To achieve the above objective, the present invention comprises: a fixing plate installed on the frame of a pallet for transporting goods;

[0023] An operating toggle clamp installed on the above-mentioned fixed plate;

[0024] A vertical frame installed vertically to the above toggle clamp;

[0025] A connecting frame positioned horizontally below the vertical frame, into which the lower end of the vertical frame is inserted;

[0026] Lifting frames respectively connected to both ends in the longitudinal direction of the above connecting frame;

[0027] It is characterized by including a stop module installed on the lifting frame and in contact with or separated from a caster module provided on a pallet for transporting goods, thereby restricting the rotation of the caster module.

[0029] In addition, the stop module is characterized by including a head coupled to the lifting frame, a body extending downward from the head, a lifting pin comprising a reinforcing member arranged to surround the body, and a movable housing having an insertion hole into which the lifting pin is inserted, which restricts the rotation of the caster module while moving up and down by the rising and falling of the lifting pin, while coming into contact with or separating from the caster module.

[0031] In addition, the vertical frame is characterized by including a vertical body having a predetermined width and extending in the vertical direction, and a catch portion formed at the bottom of the vertical body, formed to have a width relatively larger than the width of the vertical body, and positioned to be caught in a through hole of the connecting frame.

[0033] In addition, the connecting frame comprises a guide member fixed to the frame of the pallet for transporting goods, wherein the guide member comprises a lifting section that provides a lifting space corresponding to the lifting height of the vertical frame of the connecting frame, and a fixing section formed at the top and bottom of the lifting section, respectively, for fixing to the frame of the pallet for transporting goods.

[0035] In addition, the lifting frame is characterized by comprising a vertical plate in the shape of a rod extending in the vertical direction, one end of which is fixedly installed on the connecting frame; a bent portion formed by bending horizontally at the bottom of the vertical plate and having an installation groove formed by cutting to allow the stop module to be inserted; and a closing rod installed to close one end of the installation groove to prevent the inserted stop module from escaping to the outside. Effects of the invention

[0036] The present invention, constructed as described above, has the effect of enabling the vertical frame and the connecting frame to perform a lifting operation through simple operation of the operating toggle clamp, and thereby allowing the rotation of the caster to be effectively restricted or permitted by selectively contacting or separating the stop module from the caster module.

[0038] In addition, rotation limits for multiple casters can be controlled simultaneously with a single operation, which improves user convenience and reduces working time, thereby enhancing overall work efficiency.

[0040] In addition, since the stop module has a structure that physically restricts rotation by directly contacting the caster module, it has the effect of enabling a more stable and secure fixed state compared to conventional methods that rely on friction.

[0042] In addition, since the present invention consists of a relatively simple mechanical structure and can operate without a separate power source or complex control device, it has the effects of reducing manufacturing costs, facilitating assembly and maintenance, and providing excellent durability.

[0044] Furthermore, through the structural combination of the vertical frame, connecting frame, and lifting frame, it can be applied to various types of pallets for transporting goods, offering excellent versatility and the effect of stable operation in diverse work environments.

[0046] In addition to the above objectives, other objectives and features of the present invention will become apparent through the description of embodiments with reference to the accompanying drawings.

[0048] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.

[0050] Hereinafter, a preferred embodiment of the pallet caster movement adjustment module for transporting goods according to the present invention will be examined in detail with reference to the attached drawings.

[0052] First, the pallet caster movement adjustment module (1) for transporting goods according to the present invention comprises a fixed plate (10) installed on the frame of the pallet for transporting goods, an operating toggle clamp (20) installed on the fixed plate (10), a vertical frame (30) installed vertically on the toggle clamp (20), a connecting frame (40) arranged horizontally below the vertical frame (30) and into which the lower end of the vertical frame (30) is inserted, a lifting frame (50) each coupled to both ends in the longitudinal direction of the connecting frame (40), and a stop module (60) installed on the lifting frame (50) and which contacts or is separated from the caster module (100) provided on the pallet for transporting goods to limit the rotation of the caster module (100).

[0054] The above fixing plate (10) is installed on the frame of a pallet for transporting goods to stably support and fix the operating toggle clamp (20).

[0055] These fixing plates (10) may be formed in the shape of a metal plate and are configured to be closely attached to the upper or side of the frame of a pallet for transporting goods. Preferably, the fixing plates (10) may be firmly fixed to the pallet frame through various fastening means such as bolt fastening, welding, or riveting, but are not limited thereto.

[0056] Additionally, the fixed plate (10) may have a fastening hole or a mounting portion formed therein for installing an operating toggle clamp (20), thereby enabling the toggle clamp (20) to stably support a load without deformation during repeated operation. In particular, to effectively distribute the load and reaction force generated during the operation of the toggle clamp (20), the fixed plate (10) may be formed with a thickness greater than a predetermined thickness or additional reinforcing ribs may be formed.

[0057] In addition, the fixed plate (10) performs the function of setting the reference position of the toggle clamp (20) connected to the vertical frame (30), thereby maintaining the alignment of the entire lifting structure and ensuring smooth operation. Accordingly, the fixed plate (10) plays an important role in securing the structural stability and operational reliability of the present invention.

[0058] Meanwhile, the shape, size, and installation position of the above-mentioned fixed plate (10) can be varied depending on the structure and usage environment of the pallet for transporting goods to which it is applied, and multiple plates may be installed as needed.

[0059] Accordingly, the fixed plate (10) enables stable support and load transfer of the operating toggle clamp (20), thereby improving the reliability and durability of the entire caster movement adjustment module.

[0061] The above toggle clamp (20) provides a driving force to raise and lower the vertical frame (30) according to the user's operation, and is installed on the fixed plate (10) to control the operation of the entire caster movement adjustment module.

[0062] The above toggle clamp (20) has a toggle structure in which the link mechanism is converted into linear motion according to the rotation of the lever, and is configured to stably maintain the set position without applying a separate force after operation by forming an over-center state based on a certain position.

[0063] More specifically, the toggle clamp (20) may be configured to include an operating lever (21) that is grasped and rotated by a user, a link member (22) that moves in a straight direction in conjunction with the rotation of the operating lever (21), and an operating part (23) that is coupled to the link member (22) and generates a pressing or tensile force transmitted to a vertical frame (30). However, this configuration is merely an example, and it is understood that it can be modified and applied to various types of toggle mechanisms.

[0064] In addition, the toggle clamp (20) is configured to be firmly installed on the fixed plate (10) so as to ensure stable operation without shaking even during repetitive operation, and it is preferable that it be formed of a metal material so as to effectively support the load generated during operation.

[0065] In addition, the toggle clamp (20) is connected directly or indirectly to the vertical frame (30) and configured so that the vertical frame (30) rises or falls according to the operation of the lever. Accordingly, the connecting frame (40) and the lifting frame (50) linked to the vertical frame (30) rise together, and as a result, the stop module (60) comes into contact with or separates from the caster module (100).

[0066] In particular, the toggle clamp (20) has the characteristic of being automatically fixed at a position set by the overcenter structure, so it has the advantage of being able to stably maintain the fixed or unlocked state of the caster without a separate locking device.

[0067] Meanwhile, the shape, size, and installation method of the toggle clamp (20) can be varied depending on the size of the applied papet and the required operating load, and multiple clamps may be installed as needed to provide a stronger driving force.

[0068] Accordingly, the toggle clamp (20) enables the lifting of the vertical frame (30) with only simple operation, and thereby allows for selective control of whether the caster's rotation is restricted, thereby improving the convenience of operation and reliability of the present invention.

[0070] The vertical frame (30) is raised and lowered in the vertical direction by the operation of the toggle clamp (20) and transmits operating force to the connecting frame (40) and the lifting frame (50). It may be formed as a rod or plate-shaped structure that extends in the vertical direction overall, and the upper part is connected to the toggle clamp (20) and the lower part is positioned to penetrate the connecting frame (40).

[0071] Accordingly, the linear motion resulting from the operation of the toggle clamp (20) is configured to be transmitted to the lower structure through the vertical frame (30).

[0072] More specifically, the vertical frame (30) is configured to include a vertical body (31) having a predetermined width and extending in the vertical direction, and a locking part (32) formed at the bottom of the vertical body (31).

[0074] The vertical body (31) is preferably formed of a material having sufficient rigidity, such as metal, to support the load transmitted from the toggle clamp (20) while enabling smooth lifting and lowering movements. Additionally, the outer surface of the vertical body (31) can be processed to minimize friction with the connecting frame (40) and enable stable sliding.

[0075] At the top of the vertical body (31), a connecting plate (311) is provided, which is bent in a horizontal direction and has a connecting hole (312) formed therein to which the operating part (23) of the toggle clamp (20) is connected.

[0076] The above-mentioned catch portion (32) may be integrally formed at the bottom of the vertical body (31) or separately connected, and is formed to have a width relatively larger than the width of the vertical body (31) to perform a catch function with respect to the through hole (41) formed in the connecting frame (40). That is, during the upward movement of the catch portion (32), the catch portion (32) comes into contact with the connecting frame (40) and raises it.

[0077] In particular, since the above-mentioned locking part (32) can perform a position fixing function through mechanical interference with the connecting frame (40), the vertical frame (30) is stably maintained in a set position according to the operating state of the toggle clamp (20).

[0079] Additionally, the vertical frame (30) is positioned to be movable in the vertical direction along the through hole (41) of the connecting frame (40), and is configured so that linear movement is achieved without twisting or eccentricity by guiding the movement path by the connecting frame (40) or the guide member (42).

[0080] In addition, the vertical frame (30) may be composed of one or more units, and when multiple units are installed, each vertical frame (30) may be configured to interlock with one another to achieve a more uniform lifting operation.

[0082] Meanwhile, the shape, length, and cross-sectional structure of the vertical frame (30) may be varied according to the required load conditions and installation environment, and additional reinforcing ribs or reinforcing members may be formed as needed.

[0084] The above connecting frame (40) supports the lower end of the vertical frame (30) so that it can move in the up and down direction by being inserted through it, and simultaneously supports the lifting frame (50) at both ends to synchronize the lifting operation of the entire structure. It is formed as a frame structure that extends in the horizontal direction overall, and a through hole (41) is formed in the central part through which the vertical frame (30) is inserted. Accordingly, the vertical frame (30) is configured to move in the up and down direction along the through hole (41).

[0085] Additionally, the connecting frame (40) may be configured to move up and down together with the lifting motion of the vertical frame (30), or to be guided to move within a certain range by the guide member (42). This ensures that the operating force of the vertical frame (30) is uniformly transmitted to the lifting frames (50) on both sides.

[0086] The guide member (42) serves to guide the movement of the connecting frame (40) and prevent eccentricity or twisting that occurs during the lifting operation. Looking at this in more detail, the guide member (42) is configured to include a lifting section (421) that forms a lifting space (422) so that the connecting frame (40) can move smoothly within a range corresponding to the lifting height of the vertical frame (30), and a fixing section (423) formed at the top and bottom of the lifting section (421) respectively and fixed to the frame of the pallet for transporting goods. The fixing section (423) can be firmly connected to the pallet frame through bolt fastening, welding, or other fixing means.

[0087] Multiple such guide members (42) may be arranged at mutually spaced positions.

[0089] Additionally, a lifting frame (50) is attached to each of the longitudinal ends of the connecting frame (40), and the connecting frame (40) performs the function of transmitting the rising or lowering motion transmitted from the vertical frame (30) to the lifting frame (50). Accordingly, the stop modules (60) on both sides are enabled to operate simultaneously and uniformly.

[0090] In addition, the above connecting frame (40) is preferably formed of a metal material to minimize wear caused by repetitive lifting and lowering movements and to secure structural rigidity, and reinforcing ribs or reinforcing plates may be additionally formed as needed.

[0092] Meanwhile, the shape and cross-sectional structure of the above-mentioned connecting frame (40) can be implemented in various forms such as a square frame, a circular bar, or a channel shape, and can be appropriately changed according to the structure and load conditions of the pallet to which it is applied.

[0094] The lifting frame (50) is connected to each end of the connecting frame (40) in the longitudinal direction and moves up and down in conjunction with the lifting operation of the vertical frame (30) and the connecting frame (40) to support and guide the stop module (60). It has a structure that extends in the vertical direction overall and is configured to perform a lifting operation by receiving a driving force transmitted from the connecting frame (40).

[0095] Accordingly, the lifting frame (50) functions as a direct support structure that allows the stop module (60) to move to a position where it is in contact with or separated from the caster module (100).

[0096] More specifically, the lifting frame (50) includes a rod-shaped vertical plate (51) that is fixedly installed at one end on the connecting frame (40) and extends in the vertical direction, and a bent portion (52) formed by bending in the horizontal direction at the bottom of the vertical plate (51).

[0098] The vertical plate (51) is connected to both ends of the connecting frame (40) and performs stable linear motion while moving up and down integrally with the connecting frame (40). In addition, since the vertical plate (51) serves to support the stop module (60), it is preferable that it be formed of a metal material to ensure sufficient rigidity.

[0099] A bend portion (52) formed by bending in a horizontal direction is provided at the bottom of the vertical plate (51), and an installation groove (521) is formed by cutting so that a stop module (60) can be inserted into the bend portion (52). The installation groove (521) provides a space for a part of the stop module (60) to be inserted and fixed, and allows the stop module (60) to move integrally with the lifting frame (50).

[0100] Additionally, a closing rod (522) is installed at one end of the installation groove (521) to prevent the stop module (60) inserted into the installation groove (521) from moving out. The closing rod (522) can be configured to be bolted or detachable, making it easy to replace or maintain the stop module (60) when necessary.

[0101] In addition, the lifting frame (50) may be positioned on both the left and right sides to form a symmetrical structure centered on the connecting frame (40), thereby enabling uniform caster control by allowing both stop modules (60) to be raised to the same height simultaneously.

[0103] Meanwhile, the lifting frame (50) may have additional reinforcing ribs to prevent deformation caused by repetitive lifting movements and external forces, and may be configured to perform more stable lifting movements by combining with a guide rail or sliding member as needed.

[0105] The stop module (60) is installed on the lifting frame (50) and moves in the up and down direction in conjunction with the lifting operation of the vertical frame (30) and the connecting frame (40), and selectively contacts or separates from the caster module (100) provided on the pallet for transporting goods, thereby restricting the rotation of the caster module (100).

[0106] Since this stop module (60) operates by physically inhibiting rotation by directly contacting the upper surface disk (110) of the caster module (100), it provides a more reliable and stable rotation limiting function compared to conventional friction-based brake structures.

[0107] More specifically, the stop module (60) comprises a lifting pin (61) coupled to a lifting frame (50) and a movable housing (62) inserted to be able to be lifted by the lifting pin (61).

[0109] The lifting pin (61) may be configured to include a head (611) coupled to the lifting frame (50), a body (612) extending downward from the head (611), and a reinforcing member (613) positioned to surround the body (612). The head (611) is seated or coupled to the installation groove (521) of the lifting frame (50) to fix the position of the lifting pin (61), and the body (612) is extended downward to be positioned to allow access to and from the movable housing (62).

[0110] Additionally, the reinforcing member (613) is formed to surround the outer circumference of the body (612) of the lifting pin (61) to prevent deformation caused by repeated lifting movements and external forces and to improve structural rigidity. This reinforcing member (613) may be formed in the shape of a cylindrical sleeve, but is not limited thereto and various reinforcing structures may be applied.

[0111] The body (612) of the lifting pin (61) is positioned to be able to enter and exit through a through hole (120) formed in the upper surface disk (110) of the caster module (100).

[0112] That is, when the lifting pin (61) is inserted into the through hole (120), the rotation of the upper surface disk (110) is restricted, thereby limiting the rotation of the caster module (100), and when the lifting pin (61) is separated upward from the through hole (120), the rotation of the upper surface disk (110) is possible.

[0114] The above-mentioned movable housing (62) has an insertion hole (621) into which the lifting pin (61) is inserted, and guides the path of the lifting pin (61) to rise and fall in the vertical direction when the lifting pin (61) moves up and down, and protects the lifting pin (61) from external impact.

[0115] Here, the bottom surface of the movable housing (62) may contact the top surface of the top disk (110) to provide an auxiliary role in limiting the rotation of the top disk (110). To this end, the movable housing may be made of a material with a high coefficient of friction or have an uneven surface structure formed on its surface. As an example, the movable housing (62) may be made of any one of rubber, silicone, or urethane, or a combination thereof.

[0116] In addition, the above-mentioned movable housing (62) is preferably formed of a material with excellent wear resistance, considering the characteristic of repeatedly contacting and separating from the caster module (100), and can be formed with a replaceable structure so that it can be replaced if damage occurs due to wear during use.

[0118] The stop module (60) formed as described above limits the rotation of the caster module (100) by restricting the rotation of the disk (110) when the lower end of the lifting pin (61) is lowered while inserted into the through hole (120), and the lower surface of the movable housing (62) comes into close contact with the upper surface of the disk (110).

[0119] Meanwhile, the above-mentioned through holes (120) are formed in multiple positions spaced apart from each other on the disk (110), so that when the positions of the through holes (120) and the lifting pin (61) do not align even when the caster module (100) is rotated, the caster module (100) is rotated slightly to align the positions of the through holes (120) and the lifting pin (61), thereby allowing the lifting pin (61) to be inserted into the through holes (120).

[0121] In addition, the stop module (60) may be configured to be installed on each side of the lifting frame (50) to correspond to a plurality of caster modules (100), and by operating simultaneously in conjunction with the lifting of the vertical frame (30), the rotation of the plurality of casters can be controlled collectively.

[0123] Meanwhile, the shape, size, and placement position of the stop module (60) may be varied depending on the structure and size of the caster module (100) to which it is applied, and may be extended to restrict not only the rotation of the caster but also the change of direction.

[0125] As described above, the present invention has been explained by specific details such as specific components, limited embodiments, and drawings; however, this is provided merely to aid in a more comprehensive understanding of the invention, and the invention is not limited to the above embodiments. A person skilled in the art can make various modifications and variations from this description.
