Specific details for implementing the invention
[0020] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings.
[0021] Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention. Accordingly, the embodiments described in this specification and the configurations illustrated in the drawings are merely one preferred embodiment of the invention and do not represent all of the technical spirit of the invention; therefore, it should be understood that various equivalents and modifications capable of replacing them may exist at the time of filing this application.
[0022] As illustrated in FIGS. 1 to 12, the variable pallet according to the present invention is,
[0023] It is largely composed of a pallet body (10) and reinforcing pins (20).
[0024] If we look at each component,
[0025] The above main body (10)
[0026] As shown in FIGS. 1 and 2,
[0027] It is made of a square plate-shaped structure having a pair of fork insertion holes (11) on each of the four sides.
[0028] Ultimately, the above main body (10) is a basic structure for stable loading during logistics transport, and by arranging a pair of fork insertion openings (11) on all four sides, multi-directional accessibility to forks such as forklifts or handcarts can be secured.
[0029] The above reinforcing pin (20)
[0030] As shown in FIGS. 1 and 2,
[0031] A number of pin structures are provided, each having a square cross-sectional structure that is inserted through some or all of the four sides of the main body (10).
[0032] Ultimately, after a hole is formed in the side of the main body (10) into which the reinforcing pin (20) can be inserted, the reinforcing pin (20) is forcibly inserted into the hole, thereby improving the durability and long-term usability of the main body (10).
[0033] At this time, it is preferable that the hole into which the reinforcing pin (20) is inserted in the main body (10), as well as the reinforcing pin (20) inserted therein, be formed in the main body (10) so as not to interfere with the fork inserted into the fork insertion hole (11) of the main body (10).
[0034] And it is most preferable that each of the above reinforcing pins (20) be placed in an adjacent area of the fork insertion opening (11) in the main body (10) which may be vulnerable to load.
[0035] Meanwhile, the variable pallet according to the present invention further includes an outer block (30) and a variable unit (40).
[0036] The above outer block (30) is
[0037] As illustrated in FIGS. 3 to 11,
[0038] Four block structures are provided, arranged on the four sides of the main body (10).
[0039] The above variable unit (40) is
[0040] As illustrated in FIGS. 3 to 11,
[0041] The method is for expanding the loading area of the main body (10) by moving each outer block (30) from the four sides of the main body (10) in a direction opposite to facing the four sides of the main body (10).
[0042] Square guide holes (41) formed between each fork insertion hole (11) on four sides of the main body (10),
[0043] Three inserts (42) formed to protrude from the outer block (30) toward the main body (10) side and inserted into the guide hole (41) and each fork insertion hole (11),
[0044] A pair of fork corresponding insertion holes (43) formed in the outer block (30) to correspond to each fork insertion hole (11) of the main body (10), and
[0045] A holding means (44) for fixing and releasing the above main body (10) and the above outer block (30)
[0046] It consists of including
[0047] At this time, the guide hole (41) is an insertion path formed in the main body (10) and guides the insert (42) to be accurately positioned, and each insert (42) is a structure protruding from the outer block (30) and is inserted into the guide hole (41) and the fork insertion opening (11) of the main body (10), and the corresponding insertion opening (43) guides the fork of a forklift, etc., to be inserted and finally inserted into the fork insertion opening (11) of the main body (10) even when the outer block (30) is displaced by the variable unit (40).
[0048] And as shown in FIG. 4 and FIG. 11, the holding means (44) comprises a pin hole (441) formed to penetrate vertically in the insert (42) inserted into the guide hole (41) among each insert (42), a plurality of corresponding pin holes (442) that penetrate through the upper surface of the main body (10) to communicate with the guide hole (41) and are arranged at regular intervals in the direction in which the insert (42) moves, and a holding pin (443) that passes through the pin hole (441) and is fitted into one corresponding pin hole (442) among each corresponding pin hole (442) that faces the pin hole (441).
[0049] Here, each corresponding pin hole (442) is positioned in a recess (444) that is recessed downward from the upper surface of the main body (10), so that the head of the holding pin (443) can be inserted, seated, and concealed in the recess (444). This concealment structure is intended to eliminate interference elements with the loaded goods.
[0050] Accordingly, as shown in FIG. 6, by pushing or pulling the outer block (30) in the opposite direction from the main body (10) to expand or contract the outer shape of the pallet, the loading area of the main body (10) can be expanded or contracted after expansion, thereby providing a flexible loading platform capable of accommodating loads of various sizes.
[0051] And as shown in FIGS. 7 to 9, the variable unit (40) is further provided with an inner block (45) having three fitting grooves (451) that are inserted and seated in each insert (42) while being placed in the space between the four sides of the main body (10) and the outer block (30) moved therefrom.
[0052] The inner block (45) has three fitting grooves (451) formed therein that are inserted into the insert (42), so that position fixation and prevention of shaking are possible through coupling with the insert (42), and it is possible to fill the spatial gap between the main body (10) and the outer block (30) that has moved outward from it, as well as secure structural continuity, and also contribute to maintaining rigidity and distributing load when the loading area is expanded, and provide a stable structure even when loaded for a long time.
[0053] And as shown in FIG. 7, the inner block (45) is provided in multiple numbers, each having a different width. For example, when the gap (interval) with the main body (10) is 10 cm when the outer block (30) is displaced to be expanded to the maximum, the gap can be filled using one inner block (45) with a width of 10 cm, or the gap can be filled using five inner blocks (45) with a width of 2 cm. Ultimately, the structure or quantity of the inner block (45) can be varied and changed in various ways within the range that satisfies the condition of being able to fill the gap.
[0054] And as shown in FIGS. 5 and 6, the two inserts (42) located on the outer side of each insert (42) are inserted so as to be supported on the inner wall of each fork insert (11). This allows the already formed fork insert (11) to be utilized without forming a separate hole for inserting the two inserts (42) located on the outer side, thereby securing lateral support when inserted into the fork insert (11), preventing shaking of the two inserts (42), and improving the bonding strength and durability of the entire pallet.
[0055] And as shown in FIGS. 10 and 11, the variable unit (40) is further provided with a fence (46) for supporting loaded goods that is formed to be erected on the upper surface of the inner block (45), and a plurality of grip holes (47) formed to penetrate inwardly and outwardly through the fence (46).
[0056] The above fence (46) is a structure erected vertically on the upper surface of the inner block (45) to prevent items loaded on the main body (10) from flowing down to the side, and in particular, when the outer edge of the loaded items widens due to the expansion of the loading area caused by the movement of the outer block (30) from the main body (10), the fence (46) acts as a physical boundary to ensure loading stability.
[0057] In addition, although the above fence (46) is formed integrally with the above inner block (45), it can also be implemented as a detachable structure as needed, and when implemented as a detachable structure, it can also be implemented as a structure with different heights.
[0058] The above grip hole (47) is a plurality of through holes formed in the fence (46), which allows a fixing means such as a string, band, or strap to pass through to tie or fix the load, and also helps the user to handle the inner block (45) more easily. Ultimately, this prevents shaking or falling during transport, enables flexible fixing, especially for loads of irregular shape, and provides various fixing positions as the grip hole (47) is arranged at regular intervals, thereby increasing the convenience and safety of the worker.
[0059] And as shown in FIG. 12, the variable unit (40) may further be equipped with a pushing means (48) for pressing and fixing the load, wherein the pushing means (48) comprises a hidden groove (481) formed to be recessed on the surface facing the load on the fence (46), a pushing head (482) inserted and seated hidden in the hidden groove (481), a shaft (483) inserted through the opposite surface facing the load on the fence (46) and connected to the pushing head (482), a nut (484) mounted on the opposite surface facing the load on the fence (46) and to which the shaft (483) is fastened, and an operating handle (485) coupled to the end of the shaft (483), and a plurality of such means may be arranged on the fence (46).
[0060] The above-mentioned concealed groove (481) is a space formed indented on the load contact surface of the fence (46), and the pushing head (482) is inserted in a concealed state so as not to protrude outward.
[0061] The pushing head (482) is inserted into the concealed groove (481) and performs the function of pressing or pressing the side of the load. When the user rotates the shaft (483) using the handle (485), the pushing head (482) advances and applies pressure to the load, thereby preventing shaking, and is particularly useful for irregularly shaped or uneven loads.
[0062] In addition, a cushion member (486) is further provided on the front surface of the pushing head (482), thereby preventing damage to the load as much as possible when the pushing head (482) pressurizes the load.
[0063] In describing the present invention above, the focus has been on a "variable pallet" having a specific shape and structure with reference to the attached drawings; however, the present invention is capable of various modifications and changes by those skilled in the art, and such modifications and changes should be interpreted as falling within the scope of protection of the present invention.
