Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and in particular to a suitcase. Background Technology

[0002] People usually carry suitcases when traveling. For those traveling with children or a lot of luggage, they may face the situation of having to pull the suitcase handle while holding a child or carrying other bags, which is inconvenient.

[0003] Therefore, some people allow children to sit on the suitcase or place other items on it. However, due to the limited size of suitcases, the top surface is usually small, posing a safety hazard to children and making it easy for items to slip off. Utility Model Content

[0004] Therefore, it is necessary to provide a suitcase whose top surface can safely and reliably accommodate people or objects to address the above problems.

[0005] This utility model provides a suitcase, including: a suitcase body; and a first pull rod assembly disposed on one side of the suitcase body in the width direction. The first pull rod assembly includes a first connecting rod, a first handle, and two second handles. The first connecting rod extends obliquely from its bottom end to its top end toward the side away from the suitcase body and is capable of extending out of / retracting into the suitcase body along the extension direction. The first handle is disposed at the top end of the first connecting rod and extends along the length direction of the suitcase body. The two second handles extend from both ends of the first handle toward the side closer to the suitcase body. When the first connecting rod extends out of the suitcase body, the first pull rod assembly and the top surface of the suitcase body form an accommodating space.

[0006] In the aforementioned suitcase, when the first connecting rod extends out of the suitcase body along its extension direction, the user can pull the suitcase using either the first or second handle. Simultaneously, the storage space can also be used to accommodate people or belongings. Users can allow children to sit on the top surface of the suitcase, leaning against the first handle; the first and second handles act as a guardrail, providing circumferential protection to prevent children from falling and reducing safety hazards. Alternatively, users can place bags or other items on the top surface of the suitcase, and the first and second handles can also prevent items from slipping. Furthermore, when the first connecting rod extends out of the suitcase body, the first pull rod assembly and the top surface of the suitcase create a larger storage space, which is more ergonomically designed. This makes it more comfortable for children to sit on the top surface of the suitcase, and provides more space for items. This allows the top surface of the suitcase to safely and reliably accommodate people or belongings, while also avoiding increasing the width of the suitcase, ensuring that the overall size of the suitcase meets the needs of carry-on or checked baggage.

[0007] In one embodiment, the angle α between the extension direction of the first link and the height direction of the housing satisfies: 0°<α≤5°.

[0008] This design prevents the first link from having an excessively large tilt angle, which would cause it to occupy too much space inside the housing when it retracts, or require an increase in the width of the housing.

[0009] In one embodiment, along the height direction of the housing, the maximum distance H between the top surface of the first handle and the top surface of the housing satisfies: 20cm≤H≤45cm.

[0010] This design prevents the first handle from extending too low, which could cause people or objects to easily tip over and fall; it also prevents the first handle from extending too high, which could cause people or objects to easily fall through the gap between the first handle and the top of the box; and it also prevents the first link from being too long, which could cause it to take up too much space inside the box when it retracts, or require the box to be larger.

[0011] In one embodiment, the length L of the second handle satisfies: 20cm≤L≤45cm.

[0012] This design prevents the second handle from being too short, which could cause people or objects to easily flip over the second handle from the sides and fall out; it also prevents the second handle from being too long, which could cause the second handle to protrude from the box in the width direction when the first link retracts into the box, or require an increase in the width of the box.

[0013] In one embodiment, the second handle extends along the width of the housing.

[0014] This design makes the first and second handles more organized, which facilitates their manufacturing and makes it more comfortable for children to sit on the top of the box.

[0015] In one embodiment, there are two first connecting rods, which are arranged at intervals along the length of the housing on both sides of the housing, and the top ends of the two first connecting rods are respectively connected to the two ends of the first handle.

[0016] This design ensures ample storage space, making it more comfortable for children to sit on top of the box and providing more room for items. Furthermore, the two first links ensure the overall strength of the first pull rod assembly and the stability of the first and second handles as they extend and move up and down along the first links.

[0017] In one embodiment, the first link is a telescopic rod.

[0018] This design prevents the telescopic rod from taking up too much space inside the box when the first link retracts, or from requiring an increase in the height of the box.

[0019] In one embodiment, the suitcase further includes a second pull rod assembly, the second pull rod assembly and the first pull rod assembly being respectively disposed on both sides of the suitcase body in the width direction.

[0020] With this design, the second pull rod assembly can protect children sitting on the top of the box and items placed on the top of the box, reducing the risk of children and items falling off the box.

[0021] In one embodiment, the second pull rod assembly includes a second connecting rod, a third handle, and two fourth handles. The second connecting rod extends along the height direction of the housing, the third handle is disposed at the top of the second connecting rod, and the two fourth handles extend outward from both ends of the first handle along the length direction of the housing.

[0022] With this design, when a child is sitting on top of the suitcase, an adult can pull the suitcase using the third handle, while the child can grip the fourth handle with both hands, thus improving the safety of using the suitcase.

[0023] In one embodiment, the top surface of the housing is provided with a groove, and when the first connecting rod retracts into the housing, the first handle and the two second handles are all accommodated in the groove.

[0024] With this design, when the first linkage retracts into the suitcase, the first and second handles will not protrude from the top surface of the suitcase, thus avoiding an increase in the height of the suitcase. Attached Figure Description

[0034] People usually carry suitcases when traveling. However, for those traveling with children or carrying a lot of luggage, it can be inconvenient to pull the suitcase handle while holding a child or carrying other bags. Therefore, some people let their children sit on the suitcase or place other items on it. However, due to the limited size of suitcases, the top surface is usually small, posing a safety hazard for children and making it easy for items to slip off.

[0035] To solve the above problems, such as Figures 1 to 2 As shown, this utility model provides a suitcase whose top surface can safely and reliably accommodate people or objects.

[0036] like Figures 1 to 2 As shown in the Cartesian coordinate system, when the suitcase is in an upright position, the ±X-axis is defined as the length direction of the suitcase, the ±Y-axis as the width direction, and the ±Z-axis as the height direction. The +Z-axis is the top of the suitcase, and the -Z-axis is the bottom. It should be noted that the length, width, and height dimensions of the suitcase can be adjusted as needed, and the length can be less than, equal to, or greater than the width.

[0037] like Figure 1 As shown, specifically, the suitcase includes a suitcase body 1 and a first pull rod assembly 2. The first pull rod assembly 2 is located on one side of the suitcase body 1 in the width direction. The first pull rod assembly 2 includes a first connecting rod 21, a first handle 22, and two second handles 23. The first connecting rod 21 extends obliquely from the bottom to the top towards the side away from the suitcase body 1 and can extend or retract into the suitcase body 1 along the extension direction. The first handle 22 is located at the top of the first connecting rod 21 and extends along the length direction of the suitcase body 1. The two second handles 23 extend from both ends of the first handle 22 towards the side closer to the suitcase body 1. When the first connecting rod 21 extends out of the suitcase body 1, the first pull rod assembly 2 and the top surface of the suitcase body 1 form an accommodating space. For ease of description, the following description uses the example of the first pull rod assembly 2 being located on the side of the suitcase body 1 facing the -Y axis direction, with the first connecting rod 21 extending obliquely from the bottom to the top towards the -Y axis direction. Of course, the first pull rod assembly 2 can also be located on the side of the suitcase body 1 facing the +Y axis direction as needed.

[0038] In the suitcase provided in this embodiment of the utility model, when the first connecting rod 21 extends out of the suitcase body 1 along the extension direction, the user can pull the suitcase by the first handle 22 or the second handle 23. At the same time, the storage space can also be used to accommodate people or objects. The user can let the child sit on the top surface of the suitcase body 1 with their back against the first handle 22. The first handle 22 and the second handle 23 can act as a fence to provide circumferential protection for the child, prevent the child from falling, and reduce safety hazards. Alternatively, the user can also place bags or other items on the top surface of the suitcase body 1. The first handle 22 and the second handle 23 can also prevent the items from slipping off. Furthermore, when the first link 21 extends out of the case 1, the distance between the first handle 22 and the side of the case 1 facing the +Y axis is greater than the distance between the first handle 22 and the side of the case 1 facing the +Y axis when the first link 21 retracts out of the case 1. This results in a larger carrying space formed by the first pull rod assembly 2 and the top surface of the case 1, which is more ergonomic and makes it more comfortable for children to sit on the top surface of the case 1. It also provides more space for items, allowing the top surface of the suitcase to safely and reliably accommodate people or items. Simultaneously, it avoids increasing the width of the case 1, ensuring the overall size of the suitcase meets the needs of carry-on or checked baggage. When the first link 21 retracts out of the case 1 along its extension direction, it also prevents the first pull rod assembly 2 from increasing the overall size of the suitcase when not in use.

[0039] like Figure 2 As shown in the illustrated embodiment, the angle α between the extension direction of the first connecting rod 21 and the height direction of the housing 1 satisfies: 0° < α ≤ 5°. Here, α can be any angle within the range of 0° < α ≤ 5°, such as 1°, 2°, 3°, 4°, or 5°, preferably 0° < α ≤ 3°. α ≤ 5° prevents the tilt angle of the first connecting rod 21 from being too large, which would cause the first connecting rod 21 to occupy too much space inside the housing 1 when retracted, or would require an increase in the width of the housing 1.

[0040] Of course, in other embodiments, the angle α between the extension direction of the first link 21 and the height direction of the box 1 can also be set to greater than 5° according to the size of the box 1 and the actual use needs. This utility model embodiment does not impose specific limitations here.

[0041] like Figure 2As shown in the illustrated embodiment, along the height direction of the suitcase 1, the maximum distance H between the top surface of the first handle 22 and the top surface of the suitcase 1 satisfies: 20cm ≤ H ≤ 45cm. H can be any value within the range of 20cm ≤ H ≤ 45cm, such as 20cm, 25cm, 30cm, 35cm, 40cm, or 45cm, preferably 20cm ≤ H ≤ 35cm. H ≥ 20cm prevents the first handle 22 from extending too low, which could cause people or objects to easily tip over and fall. H ≤ 45cm prevents the first handle 22 from extending too high, which could cause people or objects to easily fall through the gap between the first handle 22 and the top surface of the suitcase 1. It also prevents the first connecting rod 21 from being too long, which would occupy too much space inside the suitcase 1 when retracted, or require an increase in the size of the suitcase 1. Furthermore, within this range, H also allows the user to easily grip the first handle 22 and the second handle 23, thereby improving the safety and convenience of using the suitcase.

[0042] Of course, in other embodiments, the maximum distance H between the top surface of the first handle 22 and the top surface of the box 1 can also be set to less than 20cm or greater than 35cm depending on the size of the box 1 and the actual use needs. This utility model embodiment does not impose specific limitations here.

[0043] like Figure 2 As shown in the illustrated embodiment, the length L of the second handle 23 satisfies: 20cm ≤ L ≤ 45cm. L can be any value within the range of 20cm ≤ L ≤ 45cm, such as 20cm, 25cm, 30cm, 35cm, 40cm, or 45cm, but is preferably 20cm ≤ L ≤ 25cm. L ≥ 20cm prevents the second handle 23 from being too short, which could cause people or objects to easily flip over and fall. L ≤ 45cm prevents the second handle 23 from being too long, which could cause it to protrude beyond the width of the housing 1 when the first connecting rod 21 retracts, or necessitate an increase in the width of the housing 1.

[0044] Of course, in other embodiments, the length L of the second handle 23 can also be set to less than 20cm or greater than 25cm depending on the size of the box 1 and the actual use needs. This utility model embodiment does not impose specific limitations here.

[0045] like Figures 1 to 2As shown, in one embodiment, the second handle 23 extends along the width direction of the suitcase 1. That is, the second handle 23 is perpendicular to the first handle 22, and the plane containing the first handle 22 and the second handle 23 is parallel to the top surface of the suitcase 1. This makes the structure of the first handle 22 and the second handle 23 regular, which facilitates the processing of the first handle 22 and the second handle 23, and also makes it more comfortable for children to sit on the top surface of the suitcase 1. At the same time, when the first connecting rod 21 retracts into the suitcase 1, the first handle 22 and the second handle 23 will not occupy too much space on the top surface of the suitcase 1, or cause the overall size of the suitcase to increase.

[0046] Of course, in other embodiments, the included angle between the second handle 23 and the first handle 22 may be slightly greater than 90° or slightly less than 90°, and the planes on which the first handle 22 and the second handle 23 are located may also form a small included angle with the top surface of the box 1. The specific angles can be adjusted according to the size of the box 1 and the actual use needs. This utility model embodiment does not impose specific limitations here.

[0047] like Figure 1 As shown, in one embodiment, there are two first connecting rods 21, which are spaced apart on both sides of the box body 1 along its length. The top ends of the two first connecting rods 21 are connected to the two ends of the first handle 22, respectively. That is, the length of the first handle 22 is equal to or slightly less than the length of the box body 1 to ensure that the storage space is large enough, making it more comfortable for children to sit on the top of the box body 1, and providing more space for items. Furthermore, the two first connecting rods 21 can ensure the overall strength of the first pull rod assembly 2 and the stability of the first handle 22 and the second handle 23 when they extend and rise along the first connecting rod 21.

[0048] Of course, in other embodiments, the number of first connecting rods 21 can also be one. The first connecting rod 21 is connected to the middle position of the first handle 22, as long as the overall strength of the first pull rod assembly 2 and the stability of the first handle 22 and the second handle 23 when they move up and down along the extension direction of the first connecting rod 21 can be guaranteed. This utility model embodiment does not make specific limitations here.

[0049] like Figure 1 The suitcase body 1 is provided with a sliding groove, and the first connecting rod 21 is slidably disposed in the sliding groove to avoid increasing the length of the suitcase. Alternatively, rails can be provided on both sides of the suitcase body 1 along the length direction, and the first connecting rod 21 can be slidably disposed on the rails.

[0050] like Figure 1As shown, the first link 21 is a telescopic rod. The telescopic rod can extend and retract in the extension direction of the first link 21. The first handle 22 is provided with a button for controlling the extension and retraction of the telescopic rod, and the user can control the extension and retraction of the telescopic rod by pressing the button. The first handle 22 and the second handle 23 can adjust the height under the action of the telescopic rod. For example, the distance between the top surface of the first handle 22 and the top surface of the box 1 can be 5cm, 10cm, 15cm, 20cm, 25cm, 30cm, 35cm, 40cm, 45cm, etc., so as to facilitate the use of users of different heights in different environments. The telescopic rod can also prevent the first link 21 from occupying too much space inside the box 1 when it retracts into the box 1, or causing the height of the box 1 to need to be increased. Specifically, the telescopic rod includes an outer rod, an inner rod, and a limiting component. The number of inner rods can be one, two, or more, and multiple inner rods are nested from the inside to the outside, with the cross-sectional dimensions of the inner rods gradually increasing. The cross-sectional dimension of the outer rod is larger than that of the outermost inner rod. The limiting components have a limiting state and an unlocked state. In the limiting state, the telescopic rod cannot extend or retract along the extension direction of the first link 21. In the unlocked state, the inner rod can extend or retract relative to the outer rod along the extension direction of the first link 21. The button on the first handle 22 is used to control multiple limiting components to switch synchronously between the limiting state and the unlocked state.

[0051] like Figure 1 As shown, the suitcase also includes a second pull rod assembly 3, which, along with the first pull rod assembly 2, is located on both sides of the suitcase body 1 in the width direction. Specifically, when the first pull rod assembly 2 is located on the side of the suitcase body 1 facing the -Y-axis, the second pull rod assembly 3 is located on the side of the suitcase body 1 facing the +Y-axis. When the second pull rod assembly 3 is extended, the user can also pull the suitcase using it. Furthermore, the second pull rod assembly 3 can protect children sitting on top of the suitcase body 1 and items placed on top of the suitcase body 1, further reducing the risk of children and items falling off the suitcase body 1.

[0052] like Figure 1As shown, the second pull rod assembly 3 includes a second connecting rod, a third handle 31, and two fourth handles 32. The second connecting rod extends along the height direction of the suitcase 1, the third handle 31 is located at the top of the second connecting rod, and the two fourth handles 32 extend outward from both ends of the first handle 22 along the length direction of the suitcase 1. When a child sits on the top surface of the suitcase 1, an adult can pull the suitcase using the third handle 31, while the child can grip the fourth handles 32 with both hands, thereby further improving the safety of using the suitcase. The sum of the lengths of the third handle 31 and the two fourth handles 32 is less than or equal to the length of the suitcase 1 to prevent the fourth handles 32 from protruding beyond the length of the suitcase 1 due to excessive length. The specific lengths of the third handle 31 and the two fourth handles 32 can be set according to the size of the suitcase 1 and actual usage needs; this embodiment of the present invention does not impose specific limitations here.

[0053] The second link can also be a telescopic rod, capable of extending and retracting in the ±Z direction. The third handle 31 has a button for controlling the extension and retraction of the telescopic rod; the user can control the extension and retraction by pressing the button. The third handle 31 and the fourth handle 32 can be adjusted in height by the extension and retraction of the telescopic rod, facilitating use by users of different heights in different environments. The specific structure of the telescopic rod is similar to that of the first link 21, and will not be described in detail here. Furthermore, there can be two telescopic rods, spaced apart along the ±X axis, each connected to both ends of the third handle 31. Alternatively, there can be only one telescopic rod, connected to the middle of the third handle 31, as long as the overall strength of the second pull rod assembly 3 and the stability of the third handle 31 and the fourth handle 32 during vertical movement along the ±Z axis are guaranteed. This embodiment of the invention does not impose specific limitations here.

[0054] like Figures 1 to 2 As shown, the top surface of the suitcase 1 has a groove 11. When the first connecting rod 21 retracts into the suitcase 1, the first handle 22 and the two second handles 23 are all accommodated in the groove 11. The shape of the groove 11 matches the shape of the first handle 22 and the second handle 23, so that when the first connecting rod 21 retracts into the suitcase 1, the first handle 22 and the second handle 23 will not protrude from the top surface of the suitcase 1, thus avoiding an increase in the height of the suitcase. Similarly, when the second connecting rod retracts into the suitcase 1, the third handle 31 and the fourth handle 32 can also be accommodated in the groove 11, so that the third handle 31 and the fourth handle 32 will not protrude from the top surface of the suitcase 1.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
