Description

Technical Field

[0001] The present invention relates to a storage rack, particularly a concave square pipe lifting storage rack with a liftable storage layer.

Background Art

[0002] A prefabricated storage rack is a storage rack composed of a plurality of independent members (such as storage layers, connecting members, etc.) that can be assembled and used for storage. The design of prefabricated storage racks usually emphasizes flexibility and expandability, meeting the requirements of housing, offices, etc.

[0003] Conventionally, there is a distinction between round columns (round pipes) and square columns (square pipes). When using round pipe columns, horizontal assembly in the lateral direction is not possible, and effective expansion cannot be achieved. Therefore, it is considered advantageous to use square pipes. However, the conventional square pipe and storage rack structures have relatively complex structures and require time for assembly. Moreover, there are also disadvantages such as more production processing and packaging processes and high costs. After fixing the storage layer to the square pipe, it cannot be lifted and moved, which is inconvenient to use.

[0033] The support column assembly 110 can be divided into the first support column assembly 110A in Figure 2A and the second support column assembly 110B in Figure 2B. The bottom 112D of the first support column assembly 110A is assembled to the leg column 170 as shown in Figure 2D, and the bottom 112D of the first support column assembly 110A is installed in the assembly hole 112E. The leg column 170 includes a bottom member 172 and a fixing member 174, and the fixing member 174 is connected to the bottom member 172 and fastening member 174 is fixed in the assembly hole 112E, and the leg column 170 is assembled to the bottom 112D of the first support assembly 110A, improving the overall stability of the concave rectangular lifting storage 100 shown in Figure 1 via the leg column 170. The second support assembly 110B is installed on the connecting member 160, and the connecting member 160 of the second support assembly 110B is assembled to the first support assembly 110A, improving the overall height of the support assembly 110 in Figure 1.

[0034] Specifically, the first support assembly 110A and the second support assembly 110B in the support assembly 110 each include a concave rectangular tube 112 and a plurality of elongated hole fasteners 116, these elongated hole fasteners 116 are arranged at equal intervals on the concave plate KA, and the concave rectangular tube 112 is a rectangular tube structure having one concave shape consisting of the first plate 112A, the second plate 112B, the third plate 112C, and the concave plate KA. The present invention makes it possible to improve structural strength by changing the rectangular tube to a concave rectangular tube 112.

[0035] The first plate 112A and the second plate 112B are parallel to each other, and both sides of the third plate 112C are connected to the first plate 112A and the second plate 112B, respectively, forming a three-sided structure, and both sides of the concave plate KA are connected to the first plate 112A and the second plate 112B, respectively, so that the first plate 112A, the second plate 112B, the third plate 112C, and the concave plate KA form a three-dimensional concave structure, and the first plate Plate 112A and the second plate 112B are on opposite sides, and the concave plate KA and the third plate 112C are on opposite sides, and there is a hollow section LD between the first plate 112A, the second plate 112B, the third plate 112C, and the concave plate KA. That is, the concave rectangular tube 112 is a hollow tube with a hollow section LD inside, and in cooperation with the concave plate KA, the structural strength of the entire concave rectangular tube 112 is strengthened and it can withstand external pressure and load.

[0036] As shown in Figure 2C, the connecting member 160 can be assembled to the hollow section LD inside the concave rectangular tube 112, where the hollow section LD is the space inside the concave rectangular tube 112, and the structural form of the connecting member 160 can be adjusted according to the structural form of the concave rectangular tube 112. For example, the connecting member 160 includes a concave member 162 and a hollow rectangular member 164. Of these, the concave member 162 is connected to the hollow rectangular member 164, and protruding members 162A are provided at both ends of the concave member 162, allowing the concave member 162 to be concave and match the shape of the concave plate KA, while the hollow rectangular member 164 is rectangular.

When the connecting member 160 is inserted into the hollow section LD, the concave member 162 corresponds to the back surface of the concave plate KA, the protruding members 162A on both sides of the concave member 162 are located in the hollow recesses LD1 and LD2, and the hollow rectangular member 164 is located in the hollow main body section LD3, causing the connecting member 160 to be assembled inside the concave rectangular tube 112, and the second support assembly 110B and the first support assembly 110A to be assembled into one.

[0037] Figure 3 is an exploded diagram illustrating the assembly and fixing member and support column assembly according to the present invention. Figure 4 is an exploded diagram illustrating the concave rectangular tube and assembly and fixing member according to the present invention. Figure 5A is a perspective view illustrating the assembly and fixing member according to the present invention. Figure 5B is a side view illustrating the assembly and fixing member according to the present invention. Referring to Figures 1, 3 to 5B, the concave rectangular lifting storage 100 of the present invention further includes a plurality of assembly and fixing members 140 in addition to the support column assembly 110 and storage layer 120, of which a plurality of holes BA are provided at the upper end T1 and lower end T2 of each support column assembly 110, respectively, to which the assembly and fixing members 140 are assembled.

[0038] Using Figure 3 as an example, the support assembly 110 has an upper end T1, a lower end T2 opposite to the upper end T1, and an assembly end TA. The assembly end TA is located where the first support assembly 110A and the second support assembly 110B are combined. The first support assembly 110A has a lower end T2, which is located away from the assembly end TA of the first support assembly 110A. The second support assembly 110B has an upper end T1, which is located away from the assembly end TA of the second support assembly 110B.

[0039] Taking Figure 2A as an example, the first support assembly 110A has an assembly end TA1, and the lower end T2 and the assembly end TA1 are opposite ends. Taking Figure 2B as an example, the second support assembly 110B has an assembly end TA2, and the connecting member 160 is adjacent to the assembly end TA2, and the upper end T1 and the assembly end TA2 are opposite ends, and as shown in Figure 2C, the hollow portion LD of the assembly end TA1 is positioned where the connecting member 160 of the assembly end TA2 is assembled into one, that is, the assembly end TA shown in Figure 3.

[0040] Referring to Figures 3 and 4, the upper end T1 and lower end T2 of the support assembly 110 are each attached to one assembly fixing member 140, which is assembled from the third plate 112C of the concave rectangular tube 112, and the assembly fixing member 140 has a U-shaped structure and includes a left plate 142A, a right plate 142B, a bottom plate 144, and two assembly columns 146, which are perpendicularly connected to the left plate 142A and the right plate 142B on both sides of the bottom plate 144, with the left plate 142A and the right plate 142B being opposite sides. The two assembly columns 146 are installed on the inner surface of the bottom plate 144 and protrude.

[0041] The third plate 112C has multiple holes BA installed, and the number of assembled columns 146 matches the number of holes BA on the third plate 112C. In this embodiment, there are two assembled columns 146, and two corresponding holes BA are provided, allowing the number of holes BA and assembled columns 146 to be adjusted according to the actual situation.

[0042] Taking Figure 4 as an example, the assembly fixing member 140 is assembled from the third plate 112C of the concave rectangular tube 112. That is, if the concave plate KA is defined as the front position of the concave rectangular tube 112, the assembly fixing member 140 is attached to the rear position of the concave rectangular tube 112, or the position of the concave plate KA is the recessed position of the concave rectangular tube 112, in which case the assembly fixing member 140 cannot be attached. The left plate 142A, the right plate 142B, and the bottom plate 144 of the assembly fixing member 140 correspond to the first plate 112A, the second plate 112B, and the third plate 112C of the concave rectangular tube 112, respectively, and the position of the assembly column 146 corresponds to the hole BA on the third plate 112C.

[0043] When the assembly fixing member 140 moves in the direction of the third plate 112C, the assembled column 146 is assembled into the hole BA, the left plate 142A is attached to the surface of the first plate 112A, and the right plate 142B is attached The second plate 112B is attached to the surface, the bottom plate 144 is attached to the surface of the third plate 112C, and the assembly fixing member 140 is assembled to the concave rectangular tube 112. The assembled state can be seen in Figure 10.

[0044] In one embodiment, as shown in Figures 5A and 5B, the bottom plate 144 of the assembly fixing member 140 has an inclined structure, and the bottom plate 144 has opposing outer surfaces 144B, an inner surface 144A, and a plurality of recessed holes 144C. With respect to the inner surface 144A, the outer surface 144B has an inclination angle LM with respect to the inner surface 144A, and the maximum angle of the inclination angle LM is, for example, 1.5 degrees. Furthermore, the inclination angle LM of the outer surface 144B increases along the first assembly direction L2, and as shown in Figure 1, the first assembly direction L2 may be opposite to the stacking direction L1, or the first assembly direction L2 may be downward.

[0045] The two assembled columns 146 are arranged so as to protrude from the inner surface 144A of the bottom plate 144, and the assembled columns 146 are, for example, cylindrical or other shaped columns. The inner surface 144A is provided with a plurality of recessed holes 144C, which are a plurality of holes recessed in the inner surface 144A and do not penetrate the outer surface 144B. In embodiments not shown, the inner surface of the bottom plate among the assembly fixing members may be a smooth surface without recessed holes, and the assembled columns are installed on the inner surface.

[0046] Referring again to Figures 4 and 6, these elongated hole fasteners 116 are assembled at equal intervals on the concave plate KA, with the elongated hole fasteners 116 located in the recess KA1 of the concave plate KA, and both sides of the elongated hole fasteners 116 located between the first plate portion KA2 and the second plate portion KA3. The elongated hole fasteners 116 of the present invention are assembled onto the concave plate KA, and the elongated hole fasteners 116 are placed in appropriate positions according to the location and requirements for installing the actual storage layer. In one embodiment, the elongated hole fasteners 116 and the concave plate KA are assembled together by engagement, for example, each elongated hole fastener 116 includes two assembly fasteners 116B, the recess KA1 includes a plurality of fastener holes BC, and the positions of the two fastener holes BC correspond to the positions of the two assembly fasteners 116B, the assembly fasteners 116B engage with the fastener holes BC, and the assembly fasteners 116B are similar structures, for example, convex blocks or convex tocks. In other embodiments, the number of assembly fasteners and fastener holes may be adjusted as needed and may be one or more. In other embodiments not shown, the recess may be provided with a fastener, for example, and the elongated hole fastener may be a fastener hole corresponding to the recess, for example, and assembled together.

[0047] Furthermore, using Figure 4 as an example, the third plate 112C of the concave rectangular tube has an assembly fixing member 140 installed on it, and the concave plate KA on the opposite side of the third plate 112C has a corresponding long hole fastener 116 installed on it. On the other hand, as shown in Figure 3, since the assembly fixing member 140 is installed at the upper end T1 and lower end T2 of the support column assembly 110, multiple long hole fasteners 116 are installed on the concave plate KA, and the position with only two long hole fasteners 116 (i.e., located at the upper end T1 and lower end T2 of the support column assembly 110) corresponds to the assembly fixing member 140.

[0048] The elongated hole fastener 116 includes a fastener body 116A, a locking hole GD, and two assembly fasteners 116B. The fastener body 116A is rectangular in shape, and both sides of it are connected to the assembly fasteners 116B, respectively. That is, the two assembly fasteners 116B are connected to opposite sides of the fastener body 116A, and each of the two assembly fasteners 116B is at an angle to the fastener body 116A. Each assembly fastener 116B is a plate with one side of the fastener body 116A bent. The assembly fasteners 116B are attached to the corresponding holes BA. When the elongated hole fastener 116 is assembled to the concave plate KA, the fastener body 116A has a set distance from the concave plate KA, that is, the fastener body 116A is not attached to the surface of the concave plate KA.

[0049] The locking hole GD is in the longitudinal direction along the fastener body 116A, and this longitudinal direction is the direction pointed to by the longest axis of the fastener body 116A. The locking hole GD has opposing open end GD1 and closed end GD2, with the dimensions of the open end GD1 being larger than the dimensions of the closed end GD2. In line with the first assembly direction L2 in Figure 4 (as shown in Figure 1, the first assembly direction L2 is opposite to the stacking direction L1), the dimensions of the locking hole GD gradually decrease along the first assembly direction L2 from the open end GD1 to the closed end GD2, that is, the dimensions of the locking hole GD along the first assembly direction L2 form a tapered hole structure.

[0050] Figure 7 is a perspective view illustrating the storage layer of the present invention. Figure 8 is a partial perspective view illustrating the assembly members in the storage layer of the present invention. Referring to Figures 1, 7, and 8, the storage layer 120 of the present invention includes a movable shelf 121 and four assembly members 122, of which the movable shelf 121 is, for example, a mesh shelf. These four first assembly members 122 are provided at the four corners of the movable shelf 121. The assembly members 122 are, for example, rectangular sleeves that are substantially rectangular and have a hollow structure.

[0051] The assembly member 122 includes a first assembly part 122A, a second assembly part 122B, a third assembly part 122C, a fourth assembly part 122D, two protruding columns 122E, and a housing part CA, of which the first assembly part 122A and the second assembly part 122B are parallel, the first assembly part 122A and the second assembly part 122B are spaced apart, both sides of the first assembly part 122A are connected to the third assembly part 122C and the fourth assembly part 122D respectively, and both sides of the second assembly part 122B are connected to the third assembly part 122C and the fourth assembly part 122D respectively. The third assembly part 122C and the fourth assembly part 122D are parallel to each other, separated by a distance, and both sides of the third assembly part 122C are connected to the first assembly part 122A and the second assembly part 122B, respectively, and both sides of the fourth assembly part 122D are connected to the first assembly part 122A and the second assembly part 122B, respectively. In this way, the first assembly part 122A, the second assembly part 122B, the third assembly part 122C, and the fourth assembly part 122D are combined to form the body of the rectangular sleeve, and the internal space after assembly of the first assembly part 122A, the second assembly part 122B, the third assembly part 122C, and the fourth assembly part 122D is the housing part CA, that is, the housing part is the assembly member 122 and is the space inside the rectangular sleeve.

[0052] Of the four assembly parts (first assembly part 122A, second assembly part 122B, third assembly part 122C, and fourth assembly part 122D) of the assembly member 122 of the present invention, two assembly parts are connected to the movable shelf 121, and one of the remaining two assembly parts not connected to the movable shelf 121 is an assembly surface. As an example, in Figure 8, the first assembly part 122A and the third assembly part 122C are connected to the movable shelf 121, the second assembly part 122B and the fourth assembly part 122D are not connected to the movable shelf 121, the two protruding columns 122E are arranged inside the fourth assembly part 122D, the fourth assembly part 122D is an assembly surface, the protruding positions of the two protruding columns 122E are located inside the housing part CA, that is, the two protruding columns 122E are installed on one surface inside the assembly member 122.

[0053] Figure 9 is a perspective view illustrating the process of attaching the storage layer of the present invention to the lower end of the support assembly and the assembly fixing member. Figure 10 is a partial cross-sectional perspective view illustrating the process of attaching the storage layer of the present invention to the lower end of the support assembly and the assembly fixing member. Figure 11 is a partial perspective view illustrating the attachment of the storage layer of the present invention to the lower end of the support assembly and the assembly fixing member. Since the assembly fixing member 140 is installed at the upper end T1 and lower end T2 of the support assembly 110, the assembly process in which the storage layer 120 of the present invention is attached to the lower end T2 of the support assembly 110, and the connection structure of the assembly member 122 with the elongated hole fastener 116 and the assembly fixing member 140 will be explained with reference to Figures 9 to 11. The process of attaching the storage layer 120 to the upper end T1 of the support assembly 110 is the same as for the lower end T2, so the details will not be repeated.

[0054] The dimensions of the assembly member 122 of the present invention are larger than the dimensions of the concave rectangular tube 112 of the support column assembly 110, the storage layer 120 moves along a first assembly direction L2, which is opposite to the stacking direction L1 as shown in Figure 1, the rectangular sleeve structure of the assembly member 122 is fitted onto the outside of the concave rectangular tube 112, and the protruding column 122E moves in the direction facing the elongated hole fastener 116 (i.e., the first assembly direction L2). The storage layer 120 continues to move along the first assembly direction L2 until the protruding column 122E engages with the elongated hole fastener 116 and fixes the storage layer 120 to the concave rectangular tube 112 of the support column assembly 110, as shown in Figure 11.

[0055] Furthermore, as the aforementioned storage layer 120 continues to move along the first assembly direction L2, the dimensions of the locking hole GD along the first assembly direction L2 are tapered, so the dimensions of the locking hole GD gradually decrease from the open end GD1 to the end end GD. As the protruding column 122E moves from the open end GD1 to the end end GD2 along the first assembly direction L2, the tightness of the connection between the protruding column 122E and the locking hole GD gradually increases, making it easier for the protruding column 122E to enter the locking hole GD. As the protruding column 122E continues to move along the first assembly direction L2, the dimensions of the locking hole GD gradually decrease, fixing the protruding column 122E within the locking hole GD and informing the assembler that the assembly is complete.

[0056] In one embodiment, as the aforementioned storage layer 120 continues to move along the first assembly direction L2, the upper end T1 and lower end T2 of the support column assembly 110 are each fitted with assembly fixing members 140, and the protruding column body 122E of the assembly member 122 is fixed to the locking hole GD, while the assembly member 122 is attached to the outer surface of the corresponding assembly fixing member 140. The first assembly part 122A, the second assembly part 122B, and the third assembly part 122C of the assembly member 122 are attached to the left plate 142A, the right plate 142B, and the bottom plate 144 of the assembly fixing member 140, respectively, and the assembly fixing member 140 is positioned in the housing part CA within the assembly member 122, improving the stability of the storage layer 120 when installed on the support column assembly 110.

[0057] Furthermore, as shown in Figures 5A and 5B, the bottom plate 144 of the assembly fixing member 140 has an inclined structure, and its outer surface 144B has an inclination angle LM with respect to the inner surface 144A. As the assembly member 122 moves along the first assembly direction L2, the inclination angle LM of the outer surface 144B of the bottom plate 144 increases along the first assembly direction L2, and the tightness of the connection between the assembly member 122 and the outer surface 144B of the bottom plate 144 gradually becomes tighter. In this way, the housing section CA within the assembly member 122 can more easily accommodate the assembly fixing member 140, and as the inclination angle LM of the outer surface 144B of the bottom plate 144 increases, the outer surface 144B of the bottom plate 144 can be fixed within the housing section CA within the assembly member 122, allowing the assembler to know that the assembly is complete.

[0058] Figure 12 is a perspective view illustrating the process of attaching the storage layer of the present invention between the upper and lower ends of the support assembly. Figures 13 and 14 are perspective views illustrating the assembly process in which the storage layer of the present invention is attached between the upper and lower ends of the support assembly, respectively. Figure 15 is a partial cross-sectional perspective view illustrating how the protruding member of the storage layer of the present invention engages with the elongated hole fastener. Referring to Figures 12 to 15, the difference between Figures 12 to 15 and the aforementioned Figures 9 to 11 is that the assembly fixing member 140 is not installed between the upper end T1 and the lower end T2 of the support assembly 110 of the present invention. However, the assembly process of the joint structure of the assembly member 122 and the long hole fastener 116 to which the storage layer 120 is attached to the support assembly 110 in the aforementioned Figures 9 to 11 is the same as the assembly process of the joint structure of the assembly member 122 and the long hole fastener 116 to which the storage layer 120 is attached to the support assembly 110 in Figures 12 to 15. Therefore, Figures 12 to 15 will be used to explain the assembly process of attaching the storage layer 120, which is located between the upper end T1 and the lower end T2 of the support assembly 110 of the present invention, to the support assembly 110, and the joint structure of the assembly member 122 and the long hole fastener 116.

[0059] As shown in Figure 12, after the assembly member 122 is assembled to the lower end T2 of the support assembly 110, the dimensions of the assembly member 122 of the present invention are larger than the dimensions of the concave rectangular tube 112 of the support assembly 110, and another storage layer 120 is moved along the first assembly direction L2 on the concave rectangular tube 112, the rectangular sleeve structure of the assembly member 122 is fitted to the outside of the concave rectangular tube 112 and has one movable space, the movable space is the space formed between the assembly member 122 and the concave rectangular tube 112. The protruding column 122E moves toward the direction of the elongated hole fastener 116 (i.e., the same as the first assembly direction L2). The storage layer 120 continues to move along the first assembly direction L2 until the protruding column 122E engages with the elongated hole fastener 116, fixing the storage layer 120 to the concave rectangular tube 112 of the support assembly 110, as shown in Figure 15.

[0060] In addition, in one embodiment, as shown in Figure 13, the assembly member 122 is moved toward the second assembly direction L3, and either the second assembly direction L3 is moved horizontally, or the protruding column 122E is moved toward the concave plate KA of the concave rectangular tube 112, gradually bringing the protruding column 122E closer to the concave plate KA, so that the protruding column 122E can contact or be positioned with the elongated hole fastener 116. Next, as shown in Figure 14, the assembly member 122 moves toward the first assembly direction L2 until the protruding column 122E engages with the elongated hole fastener 116, and as shown in Figure 15, the storage layer 120 is fixed to the concave rectangular tube 112 of the support column assembly 110.

[0061] Similarly, the dimensions of the locking hole GD along the first assembly direction L2 are tapered, and the tightness of the connection between the protruding column 122E from the open end GD1 to the end end GD2 gradually increases, making it easier for the protruding column 122E to enter the locking hole GD. As the protruding column 122E continues to move along the first assembly direction L2, the dimensions of the locking hole GD gradually decrease, so that the protruding column 122E is fixed within the locking hole GD, allowing the assembler to know that the assembly is complete.

[0062] As shown in Figure 1, the assembly process is the same as in Figures 9 to 11 described above, after assembling the three storage layers 120 above the lower end T2 of the support column assembly 110, and then assembling one storage layer 120 to the upper end T1 of the support column assembly 110. As can be seen from this, the dimensions of the assembly members 122 of the storage layer 120 of the present invention are larger than the dimensions of the concave rectangular tubes 112 of the support column assembly 110, so these storage layers 120 can be moved up and down relative to the support column assembly 110 along the upward / downward direction LA. During the movement process along the first assembly direction L2, the storage layer 120 is assembled to the support column assembly 110, and the stability of assembling the storage layer 120 to the support column assembly 110 is improved by installing assembly fixing members at the upper end T1 and lower end T2 of the support column assembly 110.

[0063] Figure 16 is an enlarged perspective view illustrating the lid member and assembly member of the present invention. Referring to Figures 1 and 16, in one embodiment, the lid member 180 can be added on top of the support column assembly 110 to cover the hollow tube on top of the support column assembly 110 and improve the appearance. The lid member 180 may include a connecting structure 182, the structural form of which can be matched to the structural form of the hollow section LD, and the connecting structure 182 can be inserted into the hollow section LD to attach the lid member 180 to the support column assembly 110.

[0064] In summary, the concave rectangular tube lifting storage of the present invention has a simple and relatively stable assembly structure, and the storage layers move along the lifting direction in the support structure, improving overall ease of use.

[0065] Furthermore, this invention improves structural strength by changing the rectangular tube to a concave rectangular tube.

[0066] Furthermore, in this invention, the dimensions of the locking holes along the first assembly direction are tapered, and the dimensions of the locking holes gradually decrease from the open end to the closed end. As the protruding column moves along the first assembly direction from the open end to the closed end, the tightness between the protruding column and the locking hole gradually increases, making it easier for the protruding column to enter the locking hole. However, as the protruding column continues to move along the first assembly direction, the dimensions of the locking holes gradually decrease, firmly fixing the protruding column within the locking hole and allowing the assembler to know that the assembly is complete.

[0067] Furthermore, assembly fixing members are installed at the upper and lower ends of the support column assembly, and the protruding column bodies of the assembly members are firmly fixed into the locking holes. The second and third assembly parts of the assembly members are attached to the left plate, right plate, and bottom plate of the assembly fixing member, respectively, positioning the assembly fixing member in the storage section of the assembly member and improving the stability of the storage layer being installed on the support column assembly.

[0068] Furthermore, the bottom plate of the assembly fixing member has an inclined structure, with its outer surface having an inclination angle relative to its inner surface. As the assembly member is moved along the first assembly direction, the inclination angle of the outer surface of the bottom plate increases along the first assembly direction, gradually tightening the connection between the assembly member and the outer surface of the bottom plate. In this way, the housing within the assembly member can more easily accommodate the assembly fixing member, the inclination angle of the outer surface of the bottom plate increases, firmly fixing the outer surface of the bottom plate within the housing within the assembly member, allowing the assembler to know that the assembly is complete.

[0069] Furthermore, since the dimensions of the storage layer assembly members of the present invention are larger than the dimensions of the concave rectangular tubes of the support column assembly, the storage layer can move up and down along the upward and downward direction relative to the support column assembly. In the process of moving along the first assembly direction, the storage layer is assembled to the support column assembly, and by installing assembly fixing members at the upper and lower ends of the support column assembly, the stability of the storage layer being assembled to the support column assembly is improved.

[0070] Although the present invention has been disclosed by embodiments as described above, this does not limit the invention, and those skilled in the art can make some modifications and alterations without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention shall be based on the claims defined below. [Explanation of Symbols]
