Description

Technology Field

[0001] The present invention relates to a support system for pallets capable of loading logistics, and more specifically, to a support system for pallets having height adjustment and mutual binding functions that is positioned at the lower edge of a pallet on which logistics, i.e., cargo, is loaded, to prevent the cargo loaded on the pallet from tipping over or falling, and to enable the stable stacking of multiple pallets. Background Technology

[0003] Generally, a logistics warehouse or storage warehouse is a storage facility designed to temporarily or for a long period store all daily goods, such as various food and beverages, clothing, home appliances, miscellaneous goods, and industrial supplies, that are mass-produced in factories or production facilities. Due to the rapid development of the logistics industry in recent years, the focus has shifted from simple logistics management to the creation of new businesses, ranging from the placement of products within the warehouse to efficient inbound and outbound shipments and inventory management. Consequently, various designs and construction methods are being implemented to manage mass-produced goods more quickly and efficiently.

[0004] In such logistics warehouses, pallets are widely used to efficiently store and transport goods. Pallets are formed from materials such as wood, synthetic resin, and metal, and are transported by forklifts or forklifts with goods loaded on top of them, which has the advantage of greatly improving the efficiency of transporting and storing goods.

[0005] Meanwhile, to efficiently utilize space in a logistics warehouse, it is necessary to store pallets by stacking them vertically. To this end, conventionally, a method of stacking multiple pallets in multiple layers by installing separate pallet racks has been primarily used. The said pallet rack is composed of post bars installed vertically with respect to the floor surface, fixed load beams installed horizontally between the post bars, and connecting members, forming a structure capable of supporting pallets in multiple layers.

[0006] However, these conventional pallet racks consist of numerous components, such as multiple post bars, fixed load beams, connecting members, and foundation fasteners, which results in high manufacturing costs, complex installation work, and the need for significant time and manpower. Additionally, the structure relies on vertical connection using connecting members between post bars and horizontal length adjustment using fixed load beams, leading to reduced ease of assembly.

[0007] In addition, conventional pallet racks have a problem in that, once installed, their installation location is fixed, making it difficult to flexibly respond to changes in the spatial layout within the logistics warehouse or changes in the types and quantities of goods. In other words, if one wishes to change the location or configuration of the pallet racks as the operating environment of the logistics warehouse changes, the existing pallet racks must be completely dismantled and reinstalled, resulting in significant losses in time and cost and a significant reduction in space utilization.

[0008] Accordingly, various technologies have been proposed in the past to improve the installation convenience and structural stability of pallet racks. For example, the "pallet rack" of Korean Registered Utility Model No. 20-0459255 secures a post bar connected to one of the upper or lower ends of the post bar using a connecting member, thereby making it easy to assemble the pallet rack to suit the height of the workspace during installation, as well as convenient to replace a damaged post bar.

[0009] However, the conventional pallet rack described above is a large structure constructed by assembling multiple components such as post bars, fixed load beams, and connecting members, and the problem of requiring significant cost and time for installation has not yet been resolved. In addition, since the size of the pallet rack is fixed, there is a problem in that it is difficult to freely adjust the stacking height of the pallets (1) according to changes in the size of the cargo.

[0010] Meanwhile, when cargo is loaded directly onto pallets without using a separate pallet rack, the upper pallet is placed directly on top of the cargo loaded on the lower pallet. Since the cargo must directly support the load of the pallet, there is a problem that the cargo is prone to damage. In addition, when multiple pallets are stacked in multiple layers, there is a risk that the upper pallet may slide over or fall on the lower pallet or cargo, which can cause safety accidents.

[0011] Accordingly, there is an increasing need for research and development of a pallet support system that can form a stable and robust stacking structure by being installed directly on the pallet itself without the need for a separate large pallet rack, allows for the free adjustment of stacking height according to the size of the cargo, ensures safety through an anti-slip structure, and improves structural stability by forming an integrated frame structure by interconnecting multiple supports.

[0044] In addition, the support member (119) of the present invention is characterized by including an anti-slip plate (119a) that is attached to and installed on the lower surface.

[0046] Hereinafter, the present invention will be described in detail with reference to Drawings 1 to 13, which illustrate embodiments of the present invention.

[0048] First, the pallet (1) applied to the present invention is intended for loading cargo in various environments such as logistics warehouses, factories, and courier yards, and can be formed from materials such as wood, synthetic resin, and metal, and is formed with a general structure in which cargo is loaded on the upper surface and a space is provided in the lower surface to insert the forks of a forklift or a forklift.

[0049] At this time, the pallet (1) of the present invention is configured to include a plurality of third fixing grooves (1a) formed on the lower edge.

[0050] The third fixing groove (1a) is formed in a shape corresponding to the insertion cap (113b) which is coupled to the upper part of the height adjustment member (113) to be described in detail later, so that the main support (100) can be stably fixed to the lower surface of the pallet (1).

[0051] To explain further, the third fixing groove (1a) can be formed at various locations depending on the specifications and shape of the pallet (1), and it is preferable that it be formed at equal intervals on the edge of the pallet (1) so that a plurality of main supports (100) can be installed in a balanced manner on the edge of the pallet (1).

[0053] The main support (100), which is a major component of the present invention, is

[0054] It is installed at the bottom of the above pallet (1) and at the edge of the above pallet (1) to support cargo loaded on the pallet (1) and the pallet (1) itself, and is configured to include a body (110) formed in a vertical direction and a support leg (120) extending downward and outward from the outer surface of the body (110).

[0055] The above main support (100) is composed of multiple units and is positioned at the edges near each corner of the pallet (1), thereby distributing the load from the pallet (1) and the cargo loaded on top of it to provide stable support.

[0056] At this time, multiple main supports (100) are interconnected by an interconnecting member (200) which will be described in detail later, thereby forming an integrated frame structure and realizing a more stable and robust support structure.

[0057] The body (110) forms the center of the main support (100) and is formed in a vertical direction to perform the function of transferring the load of the pallet (1) to the floor through the support legs (120). It comprises a lifting groove (111) formed on the upper surface, at least one first fixing groove (112) formed on the side to communicate with the lifting groove (111), a height adjustment member (113) installed to be able to lift in the lifting groove (111), and a fixing pin (114) installed to penetrate the second fixing groove (113a) formed in the first fixing groove (112) and the height adjustment member (113).

[0058] The above lifting groove (111) is formed on the upper surface of the body (110) and is a space that accommodates a height adjustment member (113), which will be described in detail later, so that it can be raised and lowered in the vertical direction. It is preferable that the height adjustment member (113) be formed in a shape corresponding to its external shape so that the height adjustment member (113) can be raised and lowered stably without shaking.

[0059] The first fixing groove (112) is formed on the side of the body (110) to communicate with the lifting groove (111), and at least one is formed. It is preferable that multiple first fixing grooves (112) be formed at regular intervals in the vertical direction so that the insertion position of the fixing pin (114), which will be described in detail later, can be adjusted in multiple stages. Through this, the height of the height adjustment member (113) can be adjusted in stages, thereby allowing the stacking spacing of the pallet (1) to be set to suit the height of cargo of various specifications.

[0060] The above fixing pin (114) is installed to simultaneously penetrate the first fixing groove (112) and the second fixing groove (113a) of the height adjustment member (113) so that the height adjustment member (113) can be fixed at a set height, and after the user adjusts the height adjustment member (113) to a desired height, the fixing pin (114) is inserted to maintain the corresponding height.

[0061] The height adjustment member (113) is installed to be vertically movable in the lifting groove (111) of the body (110), and a plurality of second fixing grooves (113a) are formed to correspond to the first fixing groove (112) so as to be fixed to a desired height by the fixing pin (114), and an insertion cap (113b) is coupled to the upper part, and an upper anti-slip member (113c) is attached to the upper surface of the insertion cap (113b).

[0062] The second fixing groove (113a) is formed in multiple numbers on the side of the height adjustment member (113) and is arranged at regular intervals so as to correspond to the position of the first fixing groove (112), allowing the fixing pin (114) to pass through the first fixing groove (112) and the second fixing groove (113a) simultaneously at a height desired by the user. Through this, the height adjustment range of the pallet (1) can be set in various ways.

[0063] The above insertion cap (113b) is coupled to the upper part of the height adjustment member (113) and is formed to correspond to the third fixing groove (1a) formed on the edge of the lower surface of the pallet (1), so that it is inserted into the third fixing groove (1a), thereby allowing the main support (100) to be accurately positioned and installed on the lower surface of the pallet (1).

[0064] To further explain, the insertion cap (113b) is inserted into the third fixing groove (1a) of the pallet (1), thereby preventing the pallet (1) from moving horizontally on the main support (100), thereby enabling stable support of the pallet (1), and allowing the stacked upper pallet (1) to be accurately aligned with the lower pallet (1), so that multiple pallets (1) can be safely stacked.

[0065] The upper anti-slip member (113c) is attached to the upper surface of the insertion cap (113b), thereby increasing the frictional force between the insertion cap (113b) and the lower surface of the pallet (1) to prevent the pallet (1) from sliding, thus enabling the formation of a more stable support structure.

[0066] The upper anti-slip member (113c) may be made of an elastic material such as rubber, silicone, or urethane, and can also perform a cushioning function to mitigate the impact transmitted to the pallet (1).

[0067] The above support legs (120) are formed extending from the outer surface of the body (110), and three of them are formed extending in a triangular shape toward the lower outer direction of the body (110). A lower anti-slip member (121) is attached to the lower surface, and a connecting groove (122) is formed on the upper surface that can be screw-coupled with a connecting bolt of an interconnecting member (200) which will be described in detail later.

[0068] It is preferable that the support legs (120) are composed of three and extend outwardly from the lower outer surface of the body (110) at intervals of 120 degrees from each other to form a triangular shape. By arranging the support legs (120) in a triangular shape in this way, the load applied to the main support (100) is evenly distributed in three directions, thereby effectively preventing the pallet (1) from tipping over and forming a stable support structure.

[0069] At this time, it is preferable that the support leg (120) be extended from the lower part of the body (110) toward the outer downward direction at an angle of 40 to 50 degrees, preferably 45 degrees. This is because when the support leg (120) is formed within the angle range, the vertical and horizontal components of the load are balanced, thereby maximizing the support force on the floor surface and providing the best anti-tipping effect.

[0070] In addition, the lower part of the support leg (120) is formed in the shape of a flat foot, thereby increasing the contact area with the floor surface and enabling stable support.

[0071] The lower anti-slip member (121) is installed by being attached to the lower surface of the support leg (120), thereby increasing the frictional force between the support leg (120) and the floor surface to prevent the main support (100) from sliding on the floor.

[0072] The lower anti-slip member (121) may be made of an elastic material such as rubber, silicone, or urethane, and it is desirable to be able to perform a stable anti-slip function regardless of the material or slope of the floor surface. Through this, even if heavy cargo is loaded onto the pallet (1), the main support (100) can maintain a stable support state without detaching from the floor surface.

[0073] The above connecting groove (122) is formed on the upper surface of the support leg (120), and has screw threads formed on its inner surface so as to be screw-coupled with the one-side connecting bolt (230) and the other-side connecting bolt (260) of the interconnecting member (200), which will be described in detail later, thereby enabling a plurality of main supports (100) to be connected by the interconnecting member (200) to form an integrated frame structure.

[0074] The interconnecting member (200), which is a major component of the present invention, is

[0075] A frame structure is formed in which a plurality of main supports (100) are integrated by connecting one main support (100) and another main support (100) adjacent thereto, comprising: a one-sided assembly (210); a other-sided assembly (220) located on the other side of the one-sided assembly (210); a one-sided connecting bolt (230) rotatably installed on the rear side of the one-sided assembly (210) and screw-coupled to the connecting groove (122); a one-sided connecting bar (240) hinge-coupled to one side of the one-sided assembly (210) so that the other side can rotate in the front-rear direction; a other-sided connecting bar (250) hinge-coupled to the other side of the other-sided assembly (220) so that one side can rotate in the front-rear direction and the other side is slidably coupled to one side of the one-sided connecting bar (240); and a frame structure formed by connecting one-sided assembly (220) rotatably installed on the rear side of the other-sided assembly (220). It is configured to include a connecting bolt (260) that can be screw-coupled to the connecting groove (122).

[0076] The above-mentioned one-sided bundle (210) and the other-sided bundle (220) are respectively located at both ends of the interconnecting member (200) and are respectively connected to the one-sided main support (100) and the other-sided main support (100), and are firmly fixed to the main support (100) by being screw-coupled to the connecting groove (122) of the support leg (120) through the one-sided connecting bolt (230) and the other-sided connecting bolt (260).

[0077] The above-mentioned one-sided connecting bolt (230) is rotatably installed on the rear of the one-sided assembly (210) and screw-coupled to the connecting groove (122) of the support leg (120) to fix the one-sided assembly (210) to the one-sided main support (100), and the connection is made by screw-coupled to the connecting groove (122) as the worker rotates the one-sided connecting bolt (230).

[0078] Likewise, the other side connecting bolt (260) is rotatably installed on the rear of the other side assembly (220) and screw-coupled to the connecting groove (122) of the support leg (120) of the other side main support (100), thereby fixing the other side assembly (220) to the other side main support (100).

[0079] The above-mentioned one-sided connecting bar (240) is hinge-connected to one side of the one-sided assembly (210) so that the other side can rotate in the forward and backward directions, and the one-sided assembly (210) and the other-sided assembly (220) are connected by the combination of the one-sided connecting bar (240) and the other-sided connecting bar (250).

[0080] The other side connecting bar (250) is hinge-connected to the other side of the other side of the other side group (220) so that one side can rotate in the forward and backward direction, and the other side is connected to one side of the one side connecting bar (240) so that it can slide, thereby allowing the total length of the interconnecting member (200) to be adjusted according to the distance between the main support (100) by the sliding connection of the one side connecting bar (240) and the other side connecting bar (250).

[0081] That is, the interconnecting member (200) is hinge-connected so that the one-sided connecting bar (240) and the other-sided connecting bar (250) can be adjusted in length by sliding and can rotate in the forward and backward directions, thereby allowing for flexible connection regardless of the installation distance and direction between the main support (100) and the main support (100), so that it can be applied to pallets (1) of various sizes.

[0082] At this time, the one-sided connecting bar (240) and the other-sided connecting bar (250) can be connected to the one-sided bundle (210) and the other-sided bundle (220), respectively, in the form of a ball hinge so as to be rotatable in the up and down direction, thereby allowing each height-adjustable main support (100) to be easily connected.

[0083] Additionally, the interconnecting member (200) connects a plurality of main supports (100) to form an integrated frame structure in which the individually installed main supports (100) are distributed evenly across the entire frame, thereby achieving the effect of significantly improving structural stability. Accordingly, even when stacking multiple pallets (1) loaded with heavy cargo, they can be safely supported.

[0085] Meanwhile, the height adjustment member (113) of the present invention may be configured to include an upper fine adjustment member (113e) so as to enable fine height adjustment.

[0086] The upper fine adjustment member (113e) is screw-coupled to an upper adjustment groove (113d) formed on the upper surface of the height adjustment member (113), and the insertion cap (113b) is rotatably coupled to allow for fine adjustment of the height of the main support (100). As the user rotates the upper fine adjustment member (113e), the depth of screw coupling with the upper adjustment groove (113d) changes, thereby allowing the height of the insertion cap (113b) to be finely adjusted.

[0087] The upper adjustment groove (113d) is formed on the upper surface of the height adjustment member (113), and has screw threads formed on its inner surface so as to be screw-coupled with the upper fine adjustment member (113e).

[0088] Through this, in addition to the stepwise height adjustment by the fixed pin (114) described above, fine height adjustment through the upper fine adjustment member (113e) becomes possible, so that the height of the main support (100) can be precisely adjusted even in an environment where the floor surface is not completely flat, thereby achieving the effect of keeping the pallet (1) level.

[0089] That is, by implementing a two-stage height adjustment system of stepwise adjustment through a fixed pin (114) and continuous fine adjustment through an upper fine adjustment member (113e), more precise and stable height adjustment becomes possible.

[0090] In connection with the above, the body (110) may be configured to include a lower fine adjustment member (116) capable of finely adjusting the height of the support leg and a support member (119).

[0091] Specifically, the body (110) comprises a lower fine adjustment member (116) which is rotatably coupled to a lower adjustment groove (115) formed on the lower surface and has screw threads formed on its outer circumference, a lower fine adjustment body (117) which is screw-coupled to the lower fine adjustment member (116), a connecting bar (118) which is extended from the lower fine adjustment body (117) so as to be adjustable in length toward the support leg (120), and a support member (119) which is connected to the connecting bar (118) and coupled to surround the lower outer side of the support leg (120), and coupled so as to be slidable in the longitudinal direction of the support leg (120).

[0092] The lower adjustment groove (115) is formed on the lower surface of the body (110), and has screw threads formed on its inner surface so that the lower fine adjustment member (116) can be screw-coupled.

[0093] The lower fine adjustment member (116) has screw threads formed on its outer circumference and is screw-coupled to the lower adjustment groove (115), and is coupled so as to be rotatable, so that the depth of screw coupling with the lower adjustment groove (115) is adjusted as the user rotates the lower fine adjustment member (116).

[0094] The lower fine adjustment body (117) is screw-coupled to the lower fine adjustment member (116) and moves up and down according to the rotation of the lower fine adjustment member (116), thereby allowing the position of the connecting bar (118) and the support member (119) to be adjusted.

[0095] The above connecting bar (118) is formed to extend from the lower fine adjustment body (117) toward the support leg (120), and is formed with a telescopic or sliding structure so as to allow length adjustment, thereby enabling it to be connected to the support member (119) regardless of the arrangement angle and length of the support leg (120).

[0096] The support member (119) is connected to the connecting bar (118) and is coupled to surround the lower outer side of the support leg (120), and is coupled so as to be slidable in the longitudinal direction of the support leg (120), so that the height of the main support (100) can be finely adjusted by moving up and down along the longitudinal direction of the support leg (120) as the lower fine adjustment member (116) is adjusted.

[0097] Additionally, the support member (119) is combined in a manner that completely surrounds the lower outer side of the support leg (120), thereby performing the role of reinforcing the support leg (120) from the outside, which can improve the rigidity and durability of the support leg (120).

[0098] The above support member (119) is configured to include an anti-slip plate (119a) attached to the lower surface. The anti-slip plate (119a) is made of an elastic material such as rubber, silicone, or urethane and increases the frictional force between the support member (119) and the floor surface, thereby preventing the main support (100) from sliding on the floor surface.

[0099] That is, the lower fine adjustment structure of the present invention, consisting of a lower fine adjustment member (116), a lower fine adjustment body (117), a connecting bar (118), and a support member (119), can precisely adjust the height of the main support (100) regardless of the condition or slope of the floor surface so that the pallet (1) can always be kept horizontal, and at the same time, the effect of evenly distributing the load can be obtained by ensuring that a plurality of support legs (120) are evenly in contact with the floor surface.

[0101] The above description refers to preferred embodiments of the present invention, and the present invention is not limited to the above embodiments. A person skilled in the art to which the present invention pertains may implement the invention with various modifications within the scope of the gist of the present invention without departing from the above embodiments.
