Description

Suitcase slide Technical Field

[0001] The present invention relates to a slide device, in particular to a slide arranged on stairs for facilitating the movement of a luggage case. Background Art

[0002] In areas where public transportation hubs are located, such as train stations and subway stations, there are often many passengers traveling with suitcases. For public places without elevators, it is very inconvenient to carry suitcases up and down the stairs, especially for suitcases that are large in size and weight.

[0003] In order to facilitate carrying a suitcase up and down the stairs, a common method is to set a smooth slope on one side of the stair steps, place the pulley of the suitcase on the flat surface of the slope, and drag the suitcase up or down the stairs along the slope.

[0004] However, since most luggage cases on the market use universal casters as pulleys, which are relatively flexible, and the ramps on stairs are typically narrow, dragging a suitcase along the ramp makes it difficult to control its trajectory and keep it perfectly aligned with the slope. This can lead to the suitcase easily deviating from the slope and sliding onto the steps, making it very inconvenient to operate. Furthermore, if the suitcase accidentally slips out of your hands and slides down the ramp, it could easily collide with pedestrians, creating a dangerous situation.

[0005] Summary of the Invention

[0006] The purpose of the present invention is to provide a luggage slide that can be stably mounted directly on stairs without damaging the existing structure. By providing a central island, the slide guides and restricts the movement of the luggage, preventing it from accidentally sliding off. The specific technical solution is as follows:

[0007] A suitcase slide includes an inclined slide with an island provided on the slide. The island protrudes from the upper surface of the slide and extends along the length of the slide. In the width direction of the slide, the island is located in the middle of the slide, leaving space on both sides of the island. The slide is provided with a fixing structure, which can connect the slide to the stairs.

[0008] Furthermore, the raised height of the center island is 1-6CM.

[0009] Furthermore, the width of the center island is 10-40CM.

[0010] Furthermore, the upper surface of the center island is provided with an anti-slip structure.

[0011] Furthermore, a guide island is provided at the upper end and / or the lower end of the center island. The guide island is connected to the center island and extends in a direction away from the center island.

[0012] Furthermore, the fixing structure is a tooth portion, which includes multiple fixing plates. The size and shape of the fixing plates match the size and shape of the gap formed between the slide plate and the stair steps. The multiple fixing plates are connected in sequence to form a continuous zigzag tooth portion.

[0013] Further, the teeth are arranged at two sides of the slide; or, the teeth are arranged at one side of the slide.

[0014] Furthermore, baffles are provided on the sides of the skateboard, which protrude from the upper surface of the skateboard and extend in a direction away from the skateboard; the baffles are provided on both sides of the skateboard, or the baffles are provided on one side of the skateboard.

[0015] Furthermore, the height of the baffle is 4-86CM.

[0016] Furthermore, pulley assemblies are provided on both sides of the center island.

[0017] The luggage slide of the present invention has the following advantages:

[0018] 1. It can guide the moving direction of the suitcase so that the suitcase moves along the extension direction of the slide, preventing the suitcase from falling off the slide and onto the steps of the stairs;

[0019] 2. It can be directly and stably installed on the existing stairs without destroying the inherent structure of the stairs, and is easy to install and disassemble;

[0054] The luggage slide of the present invention includes a slide mounted on a staircase. The slide is an inclined plate structure that matches the inclination angle of the staircase. The upper end of the slide extends to the upper landing of the staircase, and the lower end extends to the lower landing of the staircase, so as to cover the entire staircase. The slide is provided with a center island, which is a long, strip-shaped boss structure that protrudes from the upper surface of the slide. The center island extends along the length of the slide. Specifically, the first end of the center island extends to the upper end of the slide, and the second end extends to the lower end of the center island, penetrating the slide in the length direction. In the width direction of the slide, the center island is located in the middle of the slide, so that the slide has space on both sides of the center island. The slide is provided with a fixing structure that can stably fix the slide on the staircase steps.

[0055] The luggage slide of the present invention can be mounted directly on existing staircase steps without disrupting the staircase's inherent structure. To move a suitcase up or down, the suitcase is moved to the first or second end of the slide, aligning the center island between the suitcase's two sets of pulleys. When the suitcase is then dragged up or down along the slide, the protruding center island lies between the two sets of pulleys, providing a guide and preventing the pulleys from excessively deflecting toward either side of the slide, thereby preventing the suitcase from detaching from the slide and sliding onto the steps. This structural design allows the luggage slide of the present invention to be compatible with suitcases of varying sizes and models, providing high versatility.

[0056] In order to better understand the purpose, structure and function of the present invention, the luggage slide of the present invention is further described in detail below with reference to the accompanying drawings.

[0057] As shown in Figures 1 to 3, the first embodiment of the present invention comprises a slide 11 having an elongated center island 12 disposed thereon. The center island 12 protrudes from the upper surface of the slide 11 and extends along the length of the slide 11. The center island 12 is located in the middle of the slide 11 in the width direction. The slide is provided with a fixing structure that stably secures the slide to a stair step.

[0058] As shown in Figure 31, compared with the method of setting a guide groove on the upper part of the skateboard or embedding a guide groove in the skateboard, the method of setting the center island on the skateboard in the present invention has better adaptability, can be applied to suitcases of different sizes and specifications, and has strong versatility.

[0059] Preferably, a guide island 13 is provided at the upper and / or lower end of the center island 12. The guide island 13 is connected to the center island 12 and extends in a direction away from the center island 12. The guide island 13 is aligned with the platform at the upper and / or lower end of the stairs. On the one hand, the guide island 13 can facilitate the rapid docking of the luggage suitcase pulleys with the center island 12 of the luggage suitcase slide, allowing the luggage suitcase to be aligned with the center island 12 before going uphill or downhill, making operation easier. On the other hand, the guide island 13 can strengthen the fixed connection between the slide 11 and the stairs, making the connection more stable and reliable. The guide island 13 is preferably a semicircular or triangular structure with narrowed ends, which further facilitates the docking of the luggage suitcase with the guide island 13.

[0060] Preferably, the height of the raised center island 12 is 1-6 cm. As shown in Figure 30 , if the suitcase accidentally slips from the luggage slide and tips over, the sidewalls of the suitcase will come into contact with the center island 12. In this situation, the upwardly raised center island 12 can lift the suitcase, disengaging the wheels from the surface of the slide 11 and leaving it suspended in the air. This prevents the suitcase from sliding down the slide and striking passersby, or significantly slows its descent, minimizing the risk of collision. When the suitcase is being dragged normally, the lower portion of the suitcase is spaced from the upper surface of the center island 12, preventing it from being affected by the movement of the suitcase.

[0061] Preferably, as shown in FIG3 , the upper surface of the center island 12 is provided with an anti-slip structure 14. The anti-slip structure 14 may be an anti-slip pattern or an anti-slip material. The anti-slip structure 14 can increase the friction coefficient between the surface of the suitcase body and the surface of the center island 12, further enhancing the effect of preventing the suitcase from sliding down the suitcase slide.

[0062] Preferably, the width of the center island 12 is 10-40 cm, which can better adapt to the distance between the two sets of pulleys of common suitcases and suitcases of different sizes, thereby greatly improving the versatility of the suitcase slide of the present invention.

[0063] As shown in Figures 4 to 7, the second embodiment of the present invention, the suitcase slide includes a slide 21, on which is provided an elongated center island 22. The center island 22 protrudes from the upper surface of the slide 21 and extends along the length direction of the slide 21; in the width direction of the slide 21, the center island 22 is located in the middle of the slide 21.

[0064] The slide 21 is connected to the staircase via a fixing structure, which can be bolts, adhesive, or the like. Preferably, the fixing structure is a tooth portion 25 as shown in Figures 4 to 7. Specifically, the tooth portion 25 comprises a plurality of triangular fixing plates, the size and shape of which match the size and shape of the gap formed between the slide 21 and the staircase steps. Each fixing plate is provided for each step, and the plurality of fixing plates are sequentially connected to form a continuous sawtooth-shaped tooth portion 25. When the slide 21 is mounted on the staircase, the tooth portion 25 can be locked onto the staircase steps, thereby securing the slide 21 to the staircase.

[0065] The teeth 25 are preferably located on both inclined sides of the slide 21. Depending on the actual use scenario, the teeth 25 can be located on both sides, as shown in FIG5 , or only on one side, as shown in FIG6 . Specifically, when the luggage slide of the present invention is installed against the left side of a staircase, the teeth 25 are preferably located only on the right side of the slide 21. In this case, the teeth 25 can completely fill and seal the gap between the right side of the slide 21 and the stair step. This arrangement not only provides a stable fixing effect, but also prevents debris and dust from entering the lower portion of the slide 21 through the gap, facilitating hygiene and cleanliness, while also enhancing the overall appearance of the luggage slide. Similarly, when the luggage slide of the present invention is installed against the right side of the staircase, the teeth 25 are preferably located only on the left side of the slide 21 to completely fill and seal the gap between the left side of the slide 21 and the stair step. When the luggage slide of the present invention is installed in the middle of the staircase, the teeth 25 are located on both sides of the slide 21 to completely fill and seal the gap between the left side of the slide 21 and the stair step. The teeth 25 are only provided on one side, which helps to reduce the overall weight of the suitcase slide, facilitates processing and installation, and reduces costs; of course, when the suitcase slide is placed against the left or right side of the stairs, the teeth 25 can also be provided on both sides of the slide plate 21 at the same time.

[0066] As shown in Figures 8 to 11, the third embodiment of the present invention, the suitcase slide includes a slide 31, on which is provided an elongated center island 32. The center island 32 protrudes from the upper surface of the slide 31 and extends along the length direction of the slide 31; in the width direction of the slide 31, the center island 32 is located in the middle of the slide 31.

[0067] The luggage slide in Example 3 is similar to Example 2, except that a guide island 33, as described in Example 1, is provided at the upper and / or lower ends of the center island 32. The guide island 33 is connected to the center island 32 and extends away from the center island 32, aligning with the upper and / or lower platforms of the stairs. The guide island 33 facilitates the quick docking of the luggage pulleys with the luggage slide's center island 32, while also strengthening the secure connection between the slide 31 and the stairs. The guide island 33 is preferably a semicircular or triangular structure with narrowed ends, further facilitating docking of the luggage with the guide island 33.

[0068] As shown in Figures 12 to 16, the fourth embodiment of the present invention, the suitcase slide includes a slide 41, on which is provided an elongated center island 42. The center island 42 protrudes from the upper surface of the slide 41 and extends along the length direction of the slide 41; in the width direction of the slide 41, the center island 42 is located in the middle of the slide 41.

[0069] Preferably, a baffle 46 is provided at the inclined side of the slide 41. The baffle 46 protrudes from the upper surface of the slide 41 and extends away from the slide 41. On the one hand, the baffle 46 further guides and restricts the sliding path of the luggage case, preventing it from deviating from the path while being dragged along the slide, slipping off the slide 41 and onto the steps. On the other hand, if the luggage case accidentally slips out of the hand, it is less likely to fall off the slide and onto the steps, thus preventing collisions with pedestrians.

[0070] Depending on the actual usage scenario, the baffle 46 can be set at both side positions of the slide 41 as shown in Figures 12 and 13, or it can be set only at the side of one side of the slide 41 as shown in Figures 14 and 15.

[0071] The height of the baffle 46 is preferably 4-86CM. This height setting can ensure the protective effect while not hindering or affecting the operational convenience of dragging the suitcase.

[0072] As shown in Figures 17 to 19, the fifth embodiment of the present invention, the suitcase slide includes a slide 51, on which is provided an elongated center island 52. The center island 52 protrudes from the upper surface of the slide 51 and extends along the length direction of the slide 51; in the width direction of the slide 51, the center island 52 is located in the middle of the slide 51.

[0073] The suitcase slide in Example 5 is similar to Example 4, except that the tooth portion 55 of Example 2 is provided between the slide 51 and the stair. The tooth portion 55 comprises a plurality of triangular fixing plates, the size and shape of which match the size and shape of the gap formed between the slide 51 and the stair steps. Each fixing plate is provided for a corresponding step, and the plurality of fixing plates are sequentially connected to form a continuous sawtooth-shaped tooth portion 55. When the slide 51 is mounted on the stair, the tooth portion 55 can be locked onto the stair step, thereby securing the slide 51 to the stair, while also providing dustproof and aesthetically pleasing effects. The tooth portions 55 are provided on the two inclined sides of the slide 51. Depending on the actual use scenario, the tooth portions 55 can be provided on both sides of the slide 51 or only on one side of the slide 51.

[0074] As shown in Figures 20 to 24 , the sixth embodiment of the present invention comprises a slide 61 having an elongated center island 62 disposed thereon. The center island 62 protrudes from the upper surface of the slide 61 and extends along the length of the slide 61. The center island 62 is located in the middle of the slide 61 in the width direction. A baffle 46 is disposed at the inclined side of the slide 61. The baffle 46 protrudes from the upper surface of the slide 61 and extends away from the slide 61.

[0075] The luggage slide in Example 6 is similar to that in Example 5, except that a guide island 63, as described in Example 1, is provided at the upper and / or lower ends of the center island 62. The guide island 63 is connected to the center island 62 and extends away from the center island 62, aligning with the upper and / or lower platforms of the stairs. The guide island 63 facilitates the quick docking of the luggage pulleys with the luggage slide center island 62, while also strengthening the secure connection between the slide 61 and the stairs. The guide island 63 is preferably a semicircular or triangular structure with narrowed ends, further facilitating the docking of the luggage with the guide island 63.

[0076] As shown in Figures 20 to 24, the suitcase slide includes a slide 71, on which a center island 72 is provided. The center island 72 protrudes from the upper surface of the slide 71 and extends along the length direction of the slide 71; in the width direction of the slide 71, the center island 72 is located in the middle of the slide 71.

[0077] The difference between the structure of the island 72 in the first to sixth embodiments is that the island 72 in the seventh embodiment includes two elongated strip-shaped protrusions arranged side by side with a gap formed between the two protrusions. Of course, the island 72 may also include multiple protrusions arranged side by side.

[0078] Preferably, as shown in Figures 28 and 29 , for the luggage slides described in Examples 1 through 6 above, pulley assemblies 8 may be further provided on both sides of the island. Since the island's guidance of the luggage primarily relies on the island's sidewalls blocking the luggage pulleys, friction may be generated when the luggage pulleys come into contact with the island's sidewalls. The pulley assemblies 8 mitigate friction between the luggage pulleys and the island's sidewalls, converting this friction into sliding motion. This, in turn, makes the luggage's movement on the slide more stable and smooth, facilitating better control of the up and down directions and reducing effort. Of course, the island structure of Example 7 may also be provided with pulley assemblies.

[0079] The present invention has been further described above with the aid of specific embodiments. However, it should be understood that the specific descriptions herein should not be construed as limiting the essence and scope of the present invention. Any modifications made to the above embodiments by a person of ordinary skill in the art after reading this specification fall within the scope of protection of the present invention. The various specific technical features described in the above specific embodiments may be combined in any suitable manner unless there is any contradiction. To avoid unnecessary repetition, the embodiments of the present invention will not further describe various possible combinations.

[0080] If the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
