Utility Model Content

[0003] This utility model provides a flexible handle assembly for a suitcase and a suitcase, which can improve the comfort and cushioning of the handle assembly, thereby enhancing user comfort.

[0004] In a first aspect, this utility model provides a flexible handle assembly for a suitcase. The flexible handle assembly includes a handle body, a flexible filling structure, and an elastic protective structure. The handle body has connecting portions at both ends and is connected to the suitcase body through the connecting portions. The handle body also has a grip portion on the side near the suitcase body. The flexible filling structure is filled inside the handle body, and at least a portion of the flexible filling structure protrudes from the grip portion. The flexible filling structure includes a polymer gel material. The elastic protective structure covers the outside of the handle body and the outside of the flexible filling structure, respectively.

[0005] This invention utilizes a flexible filling structure, comprising a polymer gel material, inside the handle body. This structure provides support while reducing pressure during gripping, improving the comfort and cushioning of the handle assembly and enhancing user comfort. Furthermore, by covering both the handle body and the flexible filling structure with elastic protective structures, the tensile strength of the flexible filling structure is ensured, enhancing its durability and strength. This also ensures the stability of the flexible filling structure during use, and the elastic protective structures further protect both the handle body and the flexible filling structure, extending the lifespan of the handle assembly.

[0006] According to the aforementioned embodiment of the first aspect of this utility model, the grip portion is provided with at least two separate first filling cavities. The first filling cavities are arranged along the length direction of the handle body, and each first filling cavity is located on a different side of the grip portion. Each first filling cavity is provided with a flexible filling structure, and the cross-sectional shape of the first filling cavity includes one of a circle and a polygon. This utility model's technical solution, by providing multiple first filling cavities on the grip portion, achieves regional filling of polymer gel material, which is beneficial for obtaining targeted support and cushioning effects at different grip positions, further reducing hand fatigue.

[0007] According to the aforementioned embodiment of the first aspect of this utility model, the first filling cavity includes a four-finger gripping area and a hand gripping area. The four-finger gripping area is located at the bottom of the gripping part, and the hand gripping area is located on the side of the gripping part. The volume of the polymer gel material filling the four-finger gripping area is larger than the filling volume of the hand gripping area. Since the four fingers are relatively thin while the palm is relatively thick when gripping, the technical solution of this utility model, by setting the volume of the polymer gel material filling the four-finger gripping area to be larger than the filling volume of the hand gripping area, helps to further alleviate fatigue when gripping with four fingers, effectively reduce pressure distribution, and achieve ergonomic comfort.

[0008] According to the aforementioned embodiments of the first aspect of this utility model, the filling thickness of the polymeric gel material in the four-finger grip area is 5-12mm, and the filling thickness of the polymeric gel material in the hand grip area is 3-8mm.

[0009] According to the aforementioned embodiment of the first aspect of this utility model, the grip portion is provided with at least two separated second filling cavities, which are sequentially arranged along the width direction of the handle body, and an elastic spacer layer is included between adjacent two second filling cavities. This utility model's technical solution, by providing multiple second filling cavities on the grip portion and including an elastic spacer layer between adjacent two second filling cavities, helps to further improve the softness of the handle assembly when gripping, while maintaining the support strength of the handle assembly.

[0010] According to the aforementioned embodiment of the first aspect of this utility model, the surface of the second filling cavity near the suitcase body is a wavy contact surface. This utility model's technical solution, by setting the surface of the second filling cavity to be wavy, facilitates a snug fit for four fingers, reduces slippage, and improves user comfort when holding the suitcase.

[0011] According to any of the foregoing embodiments of the first aspect of this utility model, the filling thickness of the polymeric gel material in each filling cavity is different; and / or, the elastic properties of the polymeric gel material in each filling cavity are different.

[0012] According to any of the foregoing embodiments of the first aspect of this utility model, the elastic protective structure includes an elastic fabric, and the outer surface of the elastic protective structure is provided with an array of breathable holes and an anti-slip structure. The technical solution of this utility model, by providing an array of breathable holes and an anti-slip structure on the outer surface of the elastic protective structure, helps to improve breathability during gripping, and increases the friction between the handle assembly and the user's hand, preventing slippage and improving safety during use.

[0013] According to any of the foregoing embodiments of the first aspect of this utility model, an elastic band is further provided along the circumferential edge of the elastic protective structure, allowing the elastic protective structure to be detachably fitted onto the outside of the flexible filling structure via the elastic band. This utility model's technical solution, by providing an elastic band along the circumferential edge of the elastic protective structure, allows the elastic protective structure to be detachably fitted onto the outside of the flexible filling structure, facilitating the removal of the elastic protective structure from the flexible filling structure for cleaning or replacement, thus improving hygiene.

[0033] This utility model provides a flexible handle assembly for a suitcase and a suitcase, which can improve the comfort and cushioning of the handle assembly, thereby enhancing user comfort.

[0034] like Figures 1 to 5 As shown, this embodiment of the utility model provides a flexible handle assembly 100 for a suitcase. The flexible handle assembly 100 includes a handle body 110, a flexible filling structure 140, and an elastic protective structure 150. The handle body 110 has connecting portions 120 at both ends, and is connected to the suitcase body 210 of the suitcase 200 via the connecting portions 120. The handle body 110 also has a grip portion 130 on the side near the suitcase body 210. The flexible filling structure 140 fills the interior of the handle body 110, and at least a portion of the flexible filling structure 140 protrudes from the grip portion 130. The flexible filling structure 140 includes a polymer gel material. Specifically, the polymer gel material can be jelly gel, silicone gel, etc., or can be replaced with thermoplastic elastomer (TPE), memory foam, or a micro-airbag structure. Multiple flexible materials can also be flexibly combined to meet the needs of different markets or users. The elastic protective structure 150 covers both the exterior of the handle body 110 and the exterior of the flexible filling structure 140.

[0035] This invention provides a flexible filling structure 140 inside the handle body 110. The flexible filling structure 140 comprises a polymer gel material, which helps reduce pressure during gripping while providing support, thus improving the comfort and cushioning of the handle assembly 100 and enhancing user comfort. Furthermore, by covering the handle body 110 and the flexible filling structure 140 with elastic protective structures 150, the tensile strength of the flexible filling structure 140 is ensured, enhancing its durability and strength, and ensuring its stability during use. The elastic protective structures 150 also protect the handle body 110 and the flexible filling structure 140, extending the service life of the handle assembly 100.

[0036] Understandably, the handle body 110 may contain a support frame, which may be made of acrylonitrile butadiene styrene (ABS), aluminum alloy or carbon fiber. Furthermore, reinforcing ribs may also be provided inside the handle body 110 to improve the support strength of the handle body 110.

[0037] like Figures 1 to 2 As shown, in one embodiment, the grip portion 130 is provided with a filling cavity filled with a polymer gel material. That is, a portion of the flexible filling structure 140 is filled within the handle body 110. The flexible filling structure 140 is semi-circular with an outward protrusion height of 5-15mm, which helps to conform to the curve of the user's palm. Figure 5 As shown, the flexible padding structure 140 can also be located on the outside of the entire handle body 110. Those skilled in the art can determine the manner in which the flexible padding structure 140 is located on the handle body 110 according to actual needs, in order to achieve better cushioning and grip.

[0038] In other embodiments of this application, such as Figures 3 to 4 As shown, multiple filling cavities can also be provided in different areas of the grip 130 according to actual needs, and each filling cavity can be filled with polymer gel material of different thickness or density to better adapt to ergonomics.

[0039] like Figure 3 As shown, the grip portion 130 has two separate first filling cavities 131, which are arranged along the length of the handle body 110. Each first filling cavity 131 is located on a different side of the grip portion 130, and each first filling cavity 131 has a flexible filling structure 140. The cross-sectional shape of the first filling cavity 131 includes a circle and a polygon. This invention provides multiple first filling cavities 131 on the grip portion 130 to achieve regional filling of polymer gel material, which helps to achieve targeted support and cushioning effects at different grip positions 130, further reducing hand fatigue.

[0040] like Figure 3As shown, specifically, the first filling cavity 131 includes a four-finger grip area 1311 and a hand grip area 1312. The four-finger grip area 1311 is located at the bottom of the grip portion 130, and the hand grip area 1312 is located on the side of the grip portion 130. The volume of the polymer gel material filled in the four-finger grip area 1311 is larger than the filling volume of the hand grip area 1312. Since the four fingers are located at the bottom of the handle body 110 and are relatively thin when gripping, while the palm is located on the side of the handle body 110 and is relatively thick, the present invention, by setting the volume of the polymer gel material filled in the four-finger grip area 1311 to be larger than the filling volume of the hand grip area 1312, is beneficial for further cushioning the weight of the suitcase 200 when lifting the suitcase, through the polymer gel material with a thickness, and can also alleviate fatigue when gripping or lifting the suitcase 200 with four fingers, effectively reducing pressure distribution and combining ergonomic comfort. The side grip area 1312 is also filled with polymer gel material, which helps to relieve the discomfort of holding the hand tightly for a long time.

[0041] In one embodiment, the filling thickness of the polymeric gel material in the four-finger gripping area 1311 is 5-12 mm, and the filling thickness of the polymeric gel material in the hand gripping area 1312 is 3-8 mm.

[0042] like Figure 4 As shown, the grip portion 130 has at least two separated second filling cavities 132, which are sequentially arranged along the width direction of the handle body 110. An elastic spacer layer 133 is provided between adjacent second filling cavities 132. Specifically, the elastic spacer layer 133 can be made of materials such as sponge or latex. In one embodiment, the grip portion 130 has two separated second filling cavities 132, with an elastic spacer layer 133 between the two second filling cavities 132. This utility model's technical solution, by providing multiple second filling cavities 132 on the grip portion 130 and including an elastic spacer layer 133 between adjacent second filling cavities 132, helps to further improve the softness of the handle assembly 100 when gripped, while maintaining the support strength of the handle assembly 100.

[0043] like Figure 4 As shown, preferably, the surface of the second filling cavity 132 near the luggage compartment body 210 is a wavy contact surface. This utility model's technical solution, by setting the surface of the second filling cavity 132 to be wavy, facilitates a snug fit for four fingers, reduces slippage, and improves user comfort when holding the luggage. Those skilled in the art can also set the surface of the second filling cavity 132 near the luggage compartment body 210 to other shapes according to actual needs to improve user comfort.

[0044] It is understood that in this application, each filling cavity can be filled with polymeric gel materials of the same or different thicknesses and elastic properties according to actual needs, so as to adaptively improve ergonomic comfort.

[0045] like Figure 1 As shown, the elastic protective structure 150 includes an elastic fabric, such as knitted fabric or elastic non-woven fabric, which is connected to the outside of the handle body 110 and the flexible filling structure 140 by sewing, bonding, or heat pressing. The elastic protective structure 150 helps to improve abrasion resistance, water and sweat resistance. The elastic protective structure 150 is provided with a ventilation hole array 151 and an anti-slip structure 152 on the outside of the elastic protective structure 150. The present invention provides a ventilation hole array 151 and an anti-slip structure 152 on the outside of the elastic protective structure 150, which helps to improve breathability when gripping and increases the friction between the handle assembly 100 and the user's hand, preventing slippage and improving safety. In an optional embodiment, the elastic protective structure 150 can be made of elastic breathable fabric, that is, it is not necessary to provide a ventilation hole array 151 on the outside of the elastic protective structure 150.

[0046] Specifically, such as Figure 1 As shown, the anti-slip structure 152 consists of anti-slip protrusions arranged at intervals. Those skilled in the art can also provide other forms of anti-slip structure 152 according to actual needs, such as... Figure 5 As shown, the anti-slip structure 152 is configured with anti-slip texture. This application does not limit the specific form of the anti-slip structure 152, and those skilled in the art can determine the form of the anti-slip structure 152 according to actual needs.

[0047] Furthermore, in an optional embodiment, an elastic band is provided along the circumferential edge of the elastic protective structure 150. The elastic band can be in the form of an elastic rubber band, allowing the elastic protective structure 150 to be detachably fitted onto the outside of the flexible filling structure 140 via the elastic band. This utility model's technical solution, by providing an elastic band along the circumferential edge of the elastic protective structure 150, allows the elastic protective structure 150 to be detachably fitted onto the outside of the flexible filling structure 140, facilitating the removal of the elastic protective structure 150 from the flexible filling structure 140 for cleaning or replacement, thus improving hygiene.

[0048] like Figures 6 to 7 As shown, this utility model embodiment also provides a suitcase 200, which includes: a suitcase body 210, a pull rod assembly 220, and a handle assembly 230. The pull rod assembly 220 and the handle assembly 230 are respectively connected to the suitcase body 210. The pull rod assembly 220 and the handle assembly 230 respectively include a flexible handle assembly 100 according to any of the foregoing embodiments of this utility model.

[0049] This invention provides a flexible handle assembly 100 within the pull rod assembly 220 and the handle assembly 230 of the luggage compartment 200. A flexible filling structure 140, comprising a polymer gel material, is incorporated inside the handle body 110. This provides support while reducing pressure during gripping, improving the comfort and cushioning of the handle assembly 100 and enhancing user comfort. Elastic protective structures 150 are then applied to both the handle body 110 and the flexible filling structure 140. This ensures the tensile strength of the flexible filling structure 140, enhancing its durability and strength, and maintaining stability during use. Furthermore, the elastic protective structure 150 protects both the handle body 110 and the flexible filling structure 140, extending the service life of the handle assembly 100.

[0050] Understandably, when the handle assembly 100 is applied to the pull rod assembly 220, the connecting part 120 is fixedly connected to the pull rod assembly 220 via mounting holes and bolts or snap-fit ​​structures, resulting in a strong connection and high stability under pulling force. The pull rod assembly 220 also includes a button 221 and a pull rod 222; pressing the button 221 allows the pull rod 222 to be pulled out or retracted from the suitcase 200. When the handle assembly 100 is applied to the carrying handle assembly 230, the connecting part 120 is connected to the outside of the suitcase 210 via a rotating connector, which includes a mounting base and a rotating shaft, allowing the carrying handle assembly 230 to rotate flexibly around the rotating shaft, facilitating the user to lift the suitcase 200 at different angles.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
