Description

Technical Field

[0001] This disclosure relates to a covering and a vehicle having the covering. Prior Technology

[0002] In vehicles such as strollers, there is often a cover on the outside of components such as armrests. This cover may be a protective sleeve covering the armrest tube. Such a cover can have a multi-layered structure, including an inner layer near the armrest tube and an outer layer away from it. In some applications, the inner layer may be a polymer material such as EVA (Ethylene Vinyl Acetate Copolymer), and the outer layer may be leather.

[0003] The raw materials for coverings are usually sheet-like. When it is desired to cover a component, the covering needs to be shaped into a tube-like form, thus requiring the two edges of the covering to be connected to each other. Since both the inner and outer layers of the covering have a certain thickness, a connection technology is needed to form a smooth, protrusion-free joint to improve the aesthetics of the covering.

[0022] While this application has been illustrated and described with reference to specific embodiments, it should not be limited to the details shown. Rather, various modifications to these details may be made within the scope of equivalents of the claims and without departing from this application.

[0023] The descriptions of directions such as "front," "back," "up," and "down" used in this document are for ease of understanding only. This application is not limited to these directions, but can be adjusted according to the actual situation.

[0024] Referring to Figure 1, the covering 100 discussed in this application is generally described. The covering 100 covers the exterior of component 200, which may be a long, narrow rod or tube, or a plate; this application is not limited to the shape of component 200. The covering 100 includes a first material layer 110 and a second material layer 120. The first material layer 110 covers the exterior of component 200, and the second material layer 120 covers the exterior of the first material layer 110. That is, the first material layer 110 is the inner layer, and the second material layer 120 is the outer layer. These two material layers can be formed of different materials; for example, the first material layer 110 may be a foam layer (e.g., a foam layer of EVA material), and the second material layer 120 may be a leather layer, but is not limited to the aforementioned materials. The thickness of the first material layer 110 may be greater than the thickness of the second material layer 120. In some embodiments, the thickness of the first material layer 110 may be 5 mm.

[0025] At least one of the first material layer 110 and the second material layer 120 may be formed by connection. For example, at the connection location shown in the box in Figure 1, the two edges of the first material layer 110 are connected to each other, and the two edges of the second material layer 120 are connected to each other. The connection location may be a region extending longitudinally, such that the cover 100 is formed into a cylindrical shape.

[0026] The enlarged views of the connection method of the prior art cover 300, as described in Figures 2 to 4, correspond to the steps of forming the connection portion at the box in Figure 1.

[0027] Figure 2 shows an unconnected existing cover 300, wherein a third material layer 310 includes two third material portions 319 to be connected, and a fourth material layer 320 includes two fourth material portions 329 to be connected. It should be understood that the two third material portions 319 can be two edges of the same material sheet, and the two fourth material portions 329 can also be two edges of the same material sheet. A reliable connection cannot be formed simply by connecting the cross-sections of the two third material portions 319 and the two fourth material portions 329 end-to-end.

[0028] Referring to Figure 3, in order to form a reliable connection, in the prior art, the two third material portions 319 and the two fourth material portions 329 are typically rolled inward (towards the side where the third material layer 310 is located), and then a connector 330 is used to penetrate the two third material portions 319 and the two fourth material portions 329. The connector 330 can be a thread, rivet, etc. This connection method requires that the third material portions 319 and the fourth material portions 329 each have some excess material on one side of the connector 330 to prevent the connector 330 from detaching.

[0029] Referring to Figure 4, when the existing cover 300, connected as described above, covers the outside of the component 200, the excess material is located inside the cover 300 and presses against the surface of the component 200, causing the existing cover 300 to bulge outward and form a raised portion R. Such a raised portion R affects the flatness of the surface of the existing cover 300, thus affecting its aesthetics.

[0030] To address the aforementioned problems, this application provides a novel covering 100. The covering 100 of the first embodiment of this application and its formation steps are described below with reference to Figures 5 to 9.

[0031] Referring to Figure 5, in the first embodiment of this application, the first material layer 110 to be connected includes a plurality of first material portions 119, each of which is respectively attached to a second material portion 129. In this embodiment, both the first material layer 110 and the second material layer 120 are sheet materials.

[0032] Referring to Figure 6A, a clearance portion 112 is formed inside the first material layer 110 before the connection is made.

[0033] The clearance portion 112 can be formed by first removing a portion of the first material layer 110, and then bonding the first material layer 110 and the second material layer 120 together. More specifically, a portion of each of the two first material portions 119 of the first material layer 110 is removed near the connection end to form the clearance portion 112. Thus, each first material portion 119 forms a cross-section 111 at adjacent locations, and the clearance portion 112 is formed between multiple cross-sections 111.

[0034] Thus, the two second material portions 129 of the second material layer 120 extend laterally beyond the two first material portions 119. Therefore, each second material portion 129 can be considered to include an adjacent bonding portion 121 and a sheet structure 122, wherein the bonding portion 121 is bonded to the first material layer 110 having a first thickness, and the sheet structure 122 is not bonded to the first material layer 110. The first material layer 110 and the second material layer 120 can be connected to each other by means of hot melt adhesive, bonding agent, or double-sided tape. The hot melt adhesive can be selected from PU hot melt adhesive, TPU hot melt adhesive, PS hot melt adhesive, and PA hot melt adhesive.

[0035] More specifically, each sheet structure 122 includes a connecting portion 123, a surplus portion 124, and a free end 125, wherein the connecting portion 123 is closer to the fitting portion 121 than the surplus portion 124, and the surplus portion 124 is located between the connecting portion 123 and the free end 125. The connecting portion 123 is used to position the connector 130, for example, the connector 130 is a thread, which is sewn to the position of the connecting portion 123 by manual or machine sewing, as will be described in detail below.

[0036] The depth H of the cross section 111 along the thickness direction of the first material portion 119 can be greater than or equal to the width T of the surplus portion 124 between the connecting portion 123 and the free end 125, so as to allow the surplus portion 124 to be accommodated in the relief portion 112, which will be described in detail below.

[0037] Referring to Figure 6B, another method of forming the clearance portion 112 within the first material layer 110 is shown, namely, firstly bonding the first material layer 110 and the second material layer 120 together, and then removing a portion of the first material layer 110. In this way, when the first material layer 110 and the second material layer 120 are difficult to completely separate at the bonding point due to adhesive or other reasons, a portion of the first material portion 119 can remain at the clearance portion 112, forming a first thickness portion 119a and a second thickness portion 119b. The first thickness portion 119a corresponds to the unremoved portion of the first material portion 119, and the second thickness portion 119b corresponds to the removed portion of the first material portion 119 (i.e., the clearance portion 112). The second thickness of the second thickness portion 119b is less than the first thickness of the first thickness portion 119a. The sheet-like structure 122 of the second material portion 129 is attached to the second thickness portion 119b. It should be noted that if the first material layer 110 and the second material layer 120 are first bonded together, and then a portion of the first material layer 110 is cut off, the connector 130 can be connected to the first material portion 119 before or after the cutting. It should be understood that when the connector 130 is connected to the connecting portion 123 in Figure 6B, connecting the two second material portions 129, the excess material portion 124 will be bent into the relief portion 112. In some embodiments, the second thickness portion 119b (i.e., the first material portion 119 with a second thickness) abuts against at least one side of the cross-section 111 of the relief portion 112.

[0038] Referring to Figure 7, the arrangement of the connector 130 in the first embodiment of this application is described. After forming the clearance portion 112 in the first material layer 110 (for example, forming the clearance portion 112 as shown in Figure 6A or 6B), the two ends of the cover 100 to be connected are brought close to each other, in particular the sheet structures 122 of the two second material portions 129 are brought close to each other, at which point the first material layer 110 is first turned over and placed outside the second material layer 120. Then, the connector 130 connects the two sheet structures 122 and the second thickness portion 119b (see Figure 6B) that may be attached to the sheet structures 122 at the connection portion 123, for example by passing through the two sheet structures 122 with a stitch or rivet to connect the two second material portions 129.

[0039] Referring to Figure 8, after connecting the two second material portions 129, the cover 100 is flipped over to cover the surface of the component 200, at which point the first material layer 110 is located inside the second material layer 120. At this time, the excess material portion 124 is accommodated in the relief portion 112 within the first material layer 110; more specifically, the excess material portion 124 bends along the connector 130 and enters the relief portion 112. The excess material portion 124 can abut against at least one side of the cross-section 111 of the relief portion 112. Since the depth H in the thickness direction of the first material portion 119 is greater than or equal to the width T of the excess material portion 124 between the connector 123 and the free end 125 (see Figures 6A and 6B), the excess material portion 124 does not extend inward beyond the inner surface of the first material layer 110 and therefore does not abut against the surface of the component 200. Therefore, the cover 100 has a flat surface at the connection point and does not form a bulge R as in the prior art (see Figure 4).

[0040] It should be understood that Figure 8 illustrates the application of the cover 100 to a pipe or rod, wherein the cover 100 surrounds the outer periphery of the component 200 (refer to Figure 1), wherein the first material layer 110 is formed by winding a sheet material into a cylindrical layer and covering the outer periphery of the component 200. However, the cover 100 of this application can also be applied to the plate shown in Figure 9, wherein the cover 100 covers only one side of the component 200.

[0041] The cover 100 according to the second embodiment of this application is described with reference to Figures 10 to 13.

[0042] Referring to Figure 10, a perspective view of the first material layer 110 and a partially enlarged cross-sectional view of the perspective view are shown. In the second embodiment, instead of forming the first material layer 110 by winding and connecting sheet material, the first material layer 110 of the cylindrical structure is formed integrally. Figure 10 shows the portion of the cylindrical structure including the recessed portion 112. The recessed portion 112 is a recessed structure formed by molding the first material layer 110. Of course, in other embodiments, the recessed portion 112 may also be formed by cutting on the complete cylindrical structure, which is not limited here.

[0043] Referring to Figure 11, similar to the first embodiment, the second material layer 120 includes two second material portions 129, each second material portion 129 including a sheet structure 122, and the two sheet structures 122 are connected at a connecting portion 123 by a connector 130 to connect the two second material portions 129. Specifically, when the component 200 is a pipe or rod, the inner side of the second material layer 120 is first turned outward, and the sheet structures 122 of the two second material portions 129 are brought close to each other. Then, the connector 130 is used to connect the two sheet structures 122 at the connecting portion 123, for example by threading or rivets through the two sheet structures 122 to connect the two second material portions 129, thus forming the second material layer 120 to be flipped as shown in Figure 11. Referring to Figure 12, the second material layer 120 shown in Figure 11 is flipped back to its inner side and then covered on the outer side of the first material layer 110, such that the excess material portion 124 of the second material layer 120 corresponds to the clearance portion 112 of the first material layer 110, resulting in a cover 100. In this way, when the cover 100 covers the outer side of the component 200, the cover 100 can also have a flat surface at the joint.

[0044] It should be noted that for the first material layer 110 of the cylindrical structure formed by integral molding in this embodiment, hot melt adhesive can be laminated and fixed on the outside of the first material layer 110 or the inside of the second material layer 120 (specifically, the hot melt adhesive can be laminated and fixed by hot pressing or vacuum adsorption, or by double-sided adhesive or other adhesive methods). After flipping the second material layer 120 over and covering the outside of the first material layer 110, the component 200 is inserted into the hollow part of the first material layer 110, and then the whole is heated and baked to completely melt the hot melt adhesive, so as to firmly adhere the first material layer 110 and the second material layer 120 together. In addition, the first material layer 110 and the component 200 can also be connected to each other by hot melt adhesive, adhesive, or double-sided adhesive, so that the covering 100 will not slide or loosen on the component 200.

[0045] Referring to Figure 13, the cover 100 according to the second embodiment can also be applied to a sheet, wherein the cover 100 covers only one side of the component 200. It should be noted that in the above embodiments, the plurality of second material portions 129 to be connected can be different edges of the same material sheet, or edges of different material sheets. For example, the edges of multiple small-area material sheets can be connected to each other to form a large-area second material layer 120.

[0046] It should be noted that the first material layer 110 and the second material layer 120 of the cover 100 provided in this application may be two adjacent layers directly bonded together; there may also be other material layers between the first material layer 110 and the second material layer 120, so the first material layer 110 and the second material layer 120 are indirectly bonded together.

[0047] The coverings of the various embodiments of this application can be applied to various components, such as handrail tubes or handrail bars of a vehicle, and the covering is a handrail glove covering the outside of the component. The vehicle is, for example, a stroller, but is not limited thereto. Figure 14 shows an example of a stroller as a vehicle. Component 200 can be a push handle tube on the upper part of the stroller for a caregiver to hold when pushing the stroller; component 200 can also be a handrail tube in front of the seat of the stroller for a child to hold when riding. The exterior of each component 200 can be covered by the covering 100. The component 200 of the stroller shown in Figure 14 is elongated and curved, generally U-shaped, and the covering 100 covers the curved portions on both sides of the component 200 and the middle portion between the two curved portions.

[0048] While preferred embodiments have been shown and described herein, it should be understood that these embodiments are given by way of example only. Many variations, modifications, and substitutions will occur to those skilled in the art without departing from the spirit of the invention. Therefore, the appended claims are intended to cover all such variations that fall within the spirit and scope of this application.
