Description

Technical Field

[0001] The utility model relates to the technical field of carriages, and in particular to a side curtain carriage with a flower fence structure. Background Art

[0002] Traditional curtain-side carriage structures present numerous practical challenges. The complex connection methods used for installation and maintenance often complicate assembly, repair, or replacement of certain sections of the carriage, such as structures like the transverse grille, requiring significant time and complex tooling. This not only increases labor costs but can also cause delays in transportation operations. Furthermore, traditional structures lack flexibility in space utilization and cannot effectively adjust to the shape and volume of different cargo. For example, when transporting large, irregularly shaped cargo, the fixed carriage space may prevent the cargo from being properly accommodated, reducing space utilization and transport adaptability.

[0003] In terms of transport safety, traditional curtain-side carriage structures are inadequate for handling the external forces of a moving vehicle. On bumpy roads, such as those navigating potholes or sharp turns, certain structures can become loose or shift, potentially compromising the integrity of the carriage and threatening the safety of the cargo. Furthermore, traditional carriage structures struggle to provide stable support for fragile and vulnerable cargo, making it susceptible to swaying and shifting during transport, increasing the risk of damage. Furthermore, traditional structures have limited strength and stability, and prolonged use can lead to structural deformation, creating safety hazards and posing a threat to transport safety.

Multiple columns are arranged on the frame and cooperate with the transverse grille to form an integrated fence structure. This structure can increase the strength and stability of the frame and share the weight and external forces borne by the car. Compared with the traditional side curtain car structure, the design of the fence structure makes the entire car more sturdy and durable, reducing safety hazards caused by structural deformation. The fence structure composed of the transverse grille and columns can effectively fix the cargo. During transportation, the cargo can be confined to the space formed by the grille, reducing the shaking and displacement of the cargo. For some fragile and vulnerable cargo, this stable fixing method can reduce the risk of damage to the cargo and ensure the integrity of the cargo during transportation.

DETAILED DESCRIPTION

[0041] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0042] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0043] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0044] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0045] Reference Figures 1 to 6, which is the first embodiment of the utility model, proposes a side curtain carriage with a flower fence structure, including a frame 1, a plurality of columns 2 arranged on the frame 1, a transverse grille 3 hingedly set on the column 2, and a connecting member 4 rotated on the column 2, and the connecting member 4 is used to connect the transverse grille 3 and the column 2.

[0046] In this embodiment, the transverse grille 3 is hingedly mounted on the uprights 2 and connected to the uprights 2 via connectors 4. This design makes the installation and removal of the transverse grille 3 very convenient. When assembling, repairing, or replacing the transverse grille 3 in the side curtain car, workers can easily perform the operation, reducing installation time and effort. For example, if a transverse grille 3 is damaged, it can be quickly removed and replaced without complex tools or extensive time. This connection between the transverse grille 3 and the uprights 2 provides a certain degree of flexibility in the vehicle compartment. Users can adjust the position or angle of the transverse grille 3 according to the actual needs of the transported goods. For example, when transporting large or irregularly shaped goods, the layout of the transverse grille 3 can be adjusted to better accommodate the goods, thereby improving the space utilization and transport adaptability of the vehicle compartment. The connectors 4 rotate on the uprights 2 and connect the transverse grille 3, forming a stable structure together with the hinged transverse grille 3. During vehicle operation, especially on bumpy roads, this connection effectively distributes the external forces acting on the transverse grille 3, preventing it from loosening or shifting. For example, when the vehicle makes a sharp turn or passes through a bumpy road, the transverse grille 3 can still remain in the correct position to ensure the integrity of the car and the safety of the cargo. Multiple columns 2 are arranged on the frame 1 and cooperate with the transverse grille 3 to form an integral flower fence structure. This structure can increase the strength and stability of the frame 1 and share the weight and external forces borne by the car. Compared with the traditional side curtain car structure, the design of the flower fence structure makes the entire car more sturdy and durable, reducing safety hazards caused by structural deformation. The flower fence structure composed of the transverse grille 3 and the columns 2 can play a good role in fixing the cargo. During transportation, the cargo can be confined to the space formed by the grille, reducing the shaking and displacement of the cargo. For some fragile and fragile cargo, this stable fixing method can reduce the risk of damage to the cargo and ensure the integrity of the cargo during transportation.

[0047] Furthermore, the transverse grid 3 includes a transverse frame 301, which is swingably set on the column 2. The transverse frame 301 has a mounting groove, and the vertical bracket 303 is set in the mounting groove. The locking member 304 is slidingly set on the vertical bracket 303, and the locking member 304 is clamped with the transverse frame 301.

[0048] In this embodiment, the transverse frame 301 is pivotally mounted on the uprights 2, providing greater flexibility in the use of the curtain-side carriage. When loading cargo, the transverse frame 301 can be adjusted appropriately based on the shape and size of the cargo, better accommodating the loading requirements of different types of cargo. For example, for taller cargo, the transverse frame 301 can be swung to a suitable angle for easier placement into the carriage, improving loading efficiency. The mounting slots on the transverse frame 301 provide a stable mounting location for the vertical supports 303. The vertical supports 303 can be adjusted and secured within the mounting slots, further enhancing the adaptability of the carriage structure. The position and number of the vertical supports 303 can be flexibly adjusted to suit the height and stability requirements of the cargo, providing better support and securement. This adjustable structural design allows the carriage to accommodate cargo of varying sizes and shapes, enhancing its versatility. The locking members 304 slide onto the vertical supports 303 and engage with the transverse frame 301, playing an important role in securing the cargo, thus enhancing cargo transportation safety. This structural design of the transverse grille 3, through the interaction of the transverse frame 301, vertical brackets 303, and locking members 304, enhances the overall structural stability of the carriage. When bearing the weight of the cargo and external forces, these components work together to distribute the pressure and reduce the risk of structural deformation. This stability is crucial for ensuring the safe transportation of cargo, especially during long-distance or heavy transport, effectively preventing damage to the carriage structure and ensuring the integrity of the cargo.

[0049] The components of the transverse grille 3 are designed to be simple and easy to install and disassemble. This facilitates assembly during the manufacturing process, improving production efficiency. Furthermore, when repairs or component replacements are necessary, the transverse grille 3 can be quickly removed and repaired individually, reducing maintenance costs and time. For example, if a vertical bracket 303 is damaged, it can be removed from the transverse frame 301 by sliding the locking member 304 and replaced without requiring extensive disassembly of the entire vehicle.

[0050] The structural design of the transverse grille 3 is not only practical but also lends the vehicle a neat and aesthetically pleasing appearance. The arrangement of the transverse frame 301 and vertical brackets 303 creates a regular pattern, enhancing the vehicle's visual appeal. Furthermore, the design of the locking member 304 coordinates with the overall structure, without detracting from the vehicle's aesthetics. This combination of aesthetics and practicality ensures that the curtain-side vehicle not only meets the needs of cargo transportation but also offers a superior visual experience for users.

[0051] Furthermore, the locking member 304 includes a main body 305, the main body 305 has an installation cavity 306 and a fixing groove 307, the fixing groove 307 is used to accommodate the transverse frame 301, the installation cavity 306 leads to the fixing groove 307, the clamping member 308 is swingably set in the fixing groove 307, and the clamping member 308 is engaged with or unengaged with the transverse frame 301 after swinging.

[0052] In this embodiment, the main body 305 of the locking member 304 is provided with a mounting cavity 306 and a fixing slot 307, and the locking member 308 is swingably mounted within the fixing slot 307. This design allows for highly flexible operation of the locking member 308. When the locking member 304 needs to be engaged with the transverse frame 301, a simple swinging motion securely engages the locking member 308. When the engagement needs to be canceled, this can be easily accomplished by swinging the locking member 308. This convenient operation significantly improves the efficiency of the carriage and facilitates the loading, unloading, and securing of cargo. When loading cargo, the position of the transverse grille 3 needs to be adjusted according to the shape and size of the cargo, necessitating flexible adjustment of the engagement position of the locking member 304. The swinging design of the locking member 308 effectively accommodates this need, making it easy to quickly adjust the carriage structure in an emergency or to perform fine adjustments during daily operation.

[0053] When the clamping member 308 swings and engages with the transverse frame 301, it provides a strong securing force, ensuring the stability of the transverse grille 3. During vehicle operation, the vehicle compartment is subject to various external forces, such as bumps and vibrations. If the locking member 304 is not securely engaged, the transverse grille 3 may become loose or shift, compromising the safe transportation of cargo. This design of the clamping member 308 engaging the transverse frame 301 effectively resists these external forces, ensuring the stability of the compartment structure and providing reliable protection for cargo.

[0054] The structure of the locking member 304 is relatively simple, consisting of a main body 305 and a clamping member 308. This simple design makes the locking member 304 easy to maintain and replace when it fails or is damaged. If the clamping member 308 is worn or damaged, it can be directly removed from the fixing slot 307 for replacement without the need for complicated disassembly and repair of the entire locking member 304. This convenient maintenance method reduces maintenance costs and time and improves the availability of the car. The design of the locking member 304 can use standardized components, which makes it easier to obtain and replace parts during production and maintenance. Standardized components can also improve production efficiency and reduce production costs, while also facilitating quality control to ensure that the performance and quality of the locking member 304 are stable and reliable.

[0055] The swinging design of the latch 308 provides a certain self-locking function for the locking member 304 when engaged, effectively preventing accidental unlocking. If the locking member 304 is accidentally unlocked during vehicle operation, the transverse grille 3 may become loose or open, causing cargo to fall or other safety accidents. This design of the latch 308 engaging the transverse frame 301 can, to a certain extent, prevent this from happening, thereby improving the safety and reliability of the vehicle compartment.

[0056] Furthermore, the clamping member 308 has an arc-shaped portion 309 and a handle portion 310. The arc-shaped portion 309 is used to clamp with the transverse frame 301. The handle portion 310 passes through the main body 305. After the handle portion 310 swings, the arc-shaped portion 309 is clamped or unclamped with the transverse frame 301. It also includes a first elastic member 5. One end of the first elastic member 5 acts on the handle portion 310, and the other end acts on the main body 305 to provide force for clamping the clamping member 308 with the transverse frame 301.

[0057] In this embodiment, the handle portion 310 of the latch 308 extends through the main body 305, allowing the user to easily engage or disengage the curved portion 309 from the transverse frame 301 by manipulating the handle 310. This design facilitates user operation, eliminating the need for additional tools and improving work efficiency. For example, when loading cargo, the user can quickly engage the latch 308 with the transverse frame 301 using the handle 310, ensuring the cargo's stability. When unloading cargo, the handle 310 can also be conveniently disengaged to open the side curtain compartment for unloading. The curved portion 309 is designed to engage the transverse frame 301, and its shape is designed to better match the transverse frame 301, providing a more secure engagement. The design of the curved portion 309 increases the contact area and strengthens the engagement force, ensuring that the latch 308 will not accidentally become loose during transportation. This reliable engagement is crucial for the safe transportation of cargo, effectively preventing the cargo from shaking or falling due to a loosening of the latch 308 during transportation.

[0058] One end of the first elastic member 5 acts on the handle 310, and the other end acts on the main body 305, providing a force to engage the clamping member 308 with the transverse frame 301. This elastic member design ensures that the clamping member 308 remains engaged, preventing it from becoming loose even when subjected to vibration or external impact during vehicle operation. Furthermore, the elastic member acts as a buffer, reducing the impact forces between the clamping member 308 and the transverse frame 301 and extending the service life of the clamping member 308 and transverse frame 301. The secure engagement of the clamping member 308 with the transverse frame 301, along with the auxiliary function of the first elastic member 5, enhances the overall structural stability of the curtain-side carriage with a flower rail structure. During vehicle operation, the carriage is subject to various external forces, such as bumps and turns. Structural instability can lead to deformation of the carriage and damage to cargo. The engagement of the clamping member 308 and the elastic member effectively disperse external forces, maintaining structural stability and providing better protection for cargo. The secure engagement and stable structure enhance carriage safety. During transportation, cargo safety is crucial. If the carriage structure is unstable or the clamping member 308 is easily loose, cargo may fall, posing a safety hazard to pedestrians and other vehicles. However, this curtain-side carriage with a lattice structure, through the design of the clamping member 308 and the action of the first elastic member 5, effectively prevents cargo from falling, improving transportation safety.

[0059] Furthermore, the frame 1 has a vertical mounting slot 101, the vertical mounting slot 101 has a through hole 102, the column 2 has a through hole 202, after the column 2 is inserted into the vertical mounting slot 101, the through hole 102 leads to the through hole 202, and also includes a first fixing member 7 slidably arranged in the through hole 102 and the through hole 202, and the first fixing member 7 is used to fix the column 2.

[0060] In this embodiment, the frame 1 has a vertical mounting slot 101 into which the column 2 can be inserted. This design makes the installation of the column 2 very convenient. When assembling the side curtain car, the column 2 only needs to be aligned with the vertical mounting slot 101 and inserted, without the need for complex installation tools and tedious installation steps. At the same time, the design of the vertical mounting slot 101 also provides an accurate installation position for the column 2, ensuring the stability and consistency of the car structure. When the column 2 is inserted into the vertical mounting slot 101, the through hole 102 leads to the through hole 202, and the first fixing member 7 can be slidably arranged within the through hole 102 and the through hole 202 to fix the column 2. This fixing method is simple and reliable, and can effectively prevent the column 2 from loosening or shifting during use. When the column 2 needs to be disassembled, the first fixing member 7 can be easily removed from the through hole 102 and the through hole 202 to easily pull the column 2 out of the vertical mounting slot 101, which is convenient and quick.

[0061] Furthermore, the first fixing member 7 has a fixing hole 701, the vertical mounting groove 101 has an extension cavity 103, and also includes a second fixing member 8, which is slidably arranged in the extension cavity 103. After sliding, the second fixing member 8 slides into or out of the fixing hole 701. One end of the second elastic member 9 acts on the second fixing member 8, and the other end acts on the cavity wall of the extension cavity 103, providing force for the second fixing member 8 to extend into the fixing hole 701.

[0062] In this embodiment, after the first fixing member 7 secures the column 2 through the through-hole 102 and the through-hole 202, the second fixing member 8 further slides into the fixing hole 701 of the first fixing member 7, forming a double fixation. This design greatly enhances the stability of the connection between the column 2 and the frame 1, ensuring that the column 2 is firmly fixed to the frame 1 under various road conditions and transportation conditions, without loosening or shifting. During vehicle operation, the vehicle compartment is subject to external forces from various directions, such as bumps, vibrations, and centrifugal force during cornering. The double fixation mechanism can better resist these external forces, preventing the column 2 from loosening or falling off due to external forces, thereby ensuring the overall structural stability and safety of the vehicle compartment. The second fixing member 8 is slidably disposed within the extension cavity 103 of the vertical mounting slot 101, making operation simple and convenient. When installing the column 2, the first fixing member 7 simply needs to be inserted into the through-hole 202 and the through-hole 102. The second fixing member 8 automatically slides into the fixing hole 701 under the action of the second elastic member 9, without the need for additional tools or complex operation steps. When removing the column 2, the second fixing member 8 can be easily removed from the frame 1 by sliding it out of the fixing hole 701 through a specific operation. This sliding design makes the installation and removal of the column 2 more efficient and quick. When replacing or repairing the column 2, it can save significant time and labor costs, improving work efficiency. It also facilitates routine maintenance and upkeep of the vehicle, ensuring it is always in good working condition. The second elastic member 9 acts on the second fixing member 8 at one end and on the wall of the extension cavity 103 at the other end, providing a force to engage the second fixing member 8 with the fixing hole 701. This elastic force ensures that the second fixing member 8 remains engaged with the fixing hole 701, preventing it from accidentally loosening due to vibration or other factors, even during long-term vehicle use. The elastic member also provides a certain buffering effect, reducing the impact force between the column 2 and the frame 1, thereby extending the service life of the component. The elastic member tightly engages the second fixing member 8 with the fixing hole 701, effectively preventing accidental unlocking. During transportation, if the column 2 is not securely fixed, it may become loose or fall off due to unexpected circumstances, leading to serious safety accidents. However, the design of this double fixing mechanism and elastic member can greatly reduce this risk and improve the safety and reliability of transportation.

[0063] Furthermore, the first fixing member 7 has a guide groove 702 , which leads to the fixing hole 701 .

[0064] In this embodiment, the guide groove 702 on the first fixing member 7 leads to the fixing hole 701, providing a clear guide path for the installation of the second fixing member 8. During installation, the second fixing member 8 can slide smoothly into the fixing hole 701 along the guide groove 702, eliminating the need for complex alignment operations. This design greatly improves the efficiency and accuracy of installation and reduces errors and difficulties during installation. The presence of the guide groove 702 allows the second fixing member 8 to quickly locate the fixing hole 701, thereby speeding up installation. This design can save a considerable amount of time and labor costs, especially in large-scale production or when frequent installation and disassembly are required.

[0065] The guide groove 702 can ensure that the second fixing member 8 slides accurately into the fixing hole 701, achieving a tight connection between the two. This accurate connection can improve the stability of the fixation and prevent the second fixing member 8 from loosening or shifting during use. This ensures that the connection between the column 2 and the frame 1 is firm and reliable, and improves the overall structural stability of the car. When the car is subjected to external forces, the guide groove 702 can help disperse stress, making the connection between the second fixing member 8 and the first fixing member 7 more stable. Through reasonable stress distribution, local stress concentration can be reduced, the service life of the fixings can be extended, and the safety and reliability of the car can be improved.

[0066] Furthermore, the first fixing member 7 is rotatably and slidably arranged in the through hole 102 and the through hole 202. The first fixing member 7 has an unlocking cavity 703, which leads to the fixing hole 701. It also includes a rotating member 10, which is rotatably arranged in the unlocking cavity 703. After the rotating member 10 rotates, it pushes the second fixing member 8 to slide out of the fixing hole 701.

[0067] In this embodiment, the first fixing member 7 is rotatably and slidably disposed within the through-hole 102 and the through-hole 202. This design allows unlocking to be achieved simply by rotating the first fixing member 7. Simultaneously, the unlocking cavity 703 of the first fixing member 7 opens into the fixing hole 701. Rotating the rotating member 10 disposed within the unlocking cavity 703 pushes the second fixing member 8 out of the fixing hole 701, thereby achieving quick unlocking. This simple and convenient operation eliminates the need for complex tools or tedious steps, significantly improving unlocking efficiency. For operators, this unlocking method is easy to master and requires no special skills or experience. Whether requiring quick unlocking in an emergency or during routine maintenance, it can be easily accomplished. This makes curtain-side carriages with flower-rail structures more convenient to use and improves work efficiency. Since unlocking requires a specific rotational movement, it effectively prevents misoperation. During transportation, if the unlocking operation is not performed correctly, the second fixing member 8 will not easily slide out of the fixing hole 701, thereby ensuring a secure and reliable connection between the column 2 and the frame 1. This design prevents structural instability in the carriage caused by misoperation, improving transportation safety. When the carriage needs repair or component replacement, this unlocking method allows for convenient removal of the column 2 from the frame 1. By rotating the first fixing member 7, the rotating member 10 pushes the second fixing member 8 out of the fixing hole 701, allowing the column 2 to be easily removed. This design makes repair and replacement more convenient, reducing maintenance costs and time.

[0068] Compact structural layout: The rotation and sliding design of the first fixing member 7, as well as the setting of the unlocking cavity 703 and the rotating member 10, make the entire structural layout more compact and reasonable. In a limited space, efficient fixing and unlocking functions are achieved, while also reducing the occupancy of the carriage space. This optimized structural design can improve the space utilization of the carriage and provide more convenience for loading and transporting goods. By pushing the second fixing member 8 out of the fixing hole 701 through the rotating member 10, the unlocking process can be smoother and the impact on the fixing member and the column 2 can be reduced. This design can improve the stability and durability of the structure and extend the service life of the fixing member and the column 2. At the same time, it can also reduce the deformation of the carriage structure caused by the unlocking operation, thereby ensuring the overall performance and safety of the carriage.

[0069] Furthermore, the rotating member 10 has a first guide surface 1001 for preventing the second fixing member 8 from sliding out of the fixing hole 701 , and the guide groove 702 has a second guide surface 704 for guiding the second fixing member 8 to slide into the fixing hole 701 .

[0070] In this embodiment, the first guide surface 1001 of the rotating member 10 provides a clear direction of force for the second fixing member 8 to slide out of the fixing hole 701. When unlocking is required, the rotating member 10 is rotated, and the first guide surface 1001 contacts the second fixing member 8. Through its specific tilt angle and shape, the first guide surface 1001 converts the rotational force of the rotating member 10 into a force that pushes the second fixing member 8 out of the fixing hole 701. This design makes the unlocking operation more precise and efficient. The operator can easily slide the second fixing member 8 out by rotating the rotating member 10 without the need for additional tools or complicated operations. The second guide surface 704 of the guide groove 702 provides guidance for the second fixing member 8 to slide into the fixing hole 701. During installation, when the second fixing member 8 approaches the fixing hole 701, the second guide surface 704 guides the second fixing member 8 to slide smoothly into the fixing hole 701, ensuring a precise connection between the fixing members. The presence of the second guide surface 704 makes the installation process more convenient, reduces errors and difficulties during installation, and improves installation efficiency and accuracy. In the fixed state, the second fixing member 8 is tightly engaged with the fixing hole 701 by the second elastic member 9. The second guide surface 704 of the guide groove 702 also provides a certain degree of auxiliary fixing. The shape and angle of the second guide surface 704 ensure that the second fixing member 8 remains in the fixed position more stably after sliding into the fixing hole 701, making it less likely to loosen or fall out. This design ensures a secure and reliable connection between the column 2 and the frame 1, improving the overall structural stability and reliability of the vehicle body.

[0071] The design of the first guide surface 1001 and the second guide surface 704 also helps prevent accidental unlocking. While the first guide surface 1001 requires a specific rotation to push the second fixing member 8 out of the fixing hole 701, the second guide surface 704 normally effectively guides the second fixing member 8 into the fixing hole 701 and maintains it securely, significantly reducing the risk of accidental unlocking. This design enhances the safety of the carriage during transportation and ensures stable transport of cargo.

[0072] When the carriage needs repair or component replacement, the design of the first guide surface 1001 and the second guide surface 704 facilitates both disassembly and installation. By rotating the rotating member 10, the first guide surface 1001 allows the second fixing member 8 to be easily pushed out of the fixing hole 701, enabling removal of the column 2. During installation, the second guide surface 704 guides the second fixing member 8 to slide quickly and accurately into the fixing hole 701, securing the column 2. This design reduces time and labor costs during repair and replacement, improving work efficiency.

[0073] The standardized design of the first guide surface 1001 and the second guide surface 704 enhances the versatility of the fastener. The same fastener design can be used on columns 2 and frames 1 of varying specifications. As long as the dimensions and shapes of the first guide surface 1001 and the second guide surface 704 meet the requirements, reliable fastening and unlocking functions can be achieved. This universal design reduces production costs and facilitates component management during production and maintenance.

[0074] Furthermore, a third elastic member 11 is included. One end of the third elastic member 11 acts on the unlocking cavity 703 , and the other end acts on the rotating member 10 to provide a stabilizing force for the rotating member 10 .

[0075] In this embodiment, one end of the third elastic member 11 acts on the unlocking chamber 703, and the other end acts on the rotating member 10, providing a stable force for the rotating member 10. During the use of the car, the rotating member 10 may be affected by various external forces, such as vibration, impact, etc. The presence of the third elastic member 11 can effectively resist these external forces, ensuring that the rotating member 10 always remains in a stable position and will not rotate or move unexpectedly due to external forces. The force of the elastic member can maintain close contact between the rotating member 10 and the unlocking chamber 703 to prevent loosening and shaking. This stable connection can improve the overall stability of the car structure and reduce the risk of loose fixation or unlocking failure due to loosening of the rotating member 10.
