[0055] Although the present invention is illustrated and described herein with reference to specific embodiments, the present invention should not be limited to the details shown. Rather, various modifications may be made to the details within the scope of equivalents of the claims and without departing from the present invention.

[0056] The descriptions of directions such as “front”, “rear”, “up” and “down” in this article are only for the convenience of understanding. The present invention is not limited to these directions but can be adjusted according to actual conditions.

[0057] Reference Figure 1The cover 100 discussed in the present application is generally described. The cover 100 is coated on the outside of the component 200. The component 200 can be a long rod or pipe, or a plate. The present application is not limited to the shape of the component 200. The cover 100 includes a first material layer 110 and a second material layer 120. The first material layer 110 covers the outside of the component 200, and the second material layer 120 covers the outside 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. The two material layers can be formed of different materials, for example, the first material layer 110 is a foam layer (such as a foam layer of EVA material), and the second material layer 120 is a leather layer, but it is not limited to the above materials. The thickness of the first material layer 110 can be greater than the thickness of the second material layer 120. In some embodiments, the thickness of the first material layer 110 can be 5 mm.

[0058] At least one of the first material layer 110 and the second material layer 120 may be formed by connection. Figure 1 At the connection part shown in the box of , 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 part may be a region extending in the longitudinal direction so that the cover 100 is formed into a cylindrical shape.

[0059] Reference Figures 2 to 4 An enlarged view of the connection method of the existing cover 300 of the prior art is described, which corresponds to Figure 1 The connection part of the box.

[0060] Figure 2 The conventional cover 300 is shown as being unconnected, wherein the third material layer 310 includes two third material portions 319 to be connected, and the fourth material layer 320 includes two fourth material portions 329 to be connected. It should be understood that the two third material portions 319 may be two edges of the same material sheet, and the two fourth material portions 329 may also be two edges of the same material sheet. If only the sections of the two third material portions 319 and the sections of the two fourth material portions 329 are connected end-to-end, a reliable connection cannot be formed.

[0061] Reference Figure 3 In order to form a reliable connection, in the prior art, the two third material parts 319 and the two fourth material parts 329 are usually rolled inward (the side where the third material layer 310 is located), and then the connecting member 330 is used to penetrate the two third material parts 319 and the two fourth material parts 329. The connecting member 330 can be a suture, a rivet, etc. This connection method requires that there is some excess material on one side of the third material part 319 and the fourth material part 329 to prevent the connecting member 330 from detaching.

[0062] Reference Figure 4 When the existing cover 300 connected in the above manner is wrapped around the outside of the component 200, the excess material is located inside the existing cover 300, and the excess material presses against the surface of the component 200, so that the existing cover 300 bulges outward to form a bulge R. Such a bulge R affects the flatness of the surface of the existing cover 300, thereby affecting its appearance.

[0063] In order to solve the above problems, the present application provides a new covering 100. Figures 5 to 9 The cover 100 and the steps for forming the cover 100 according to the first embodiment of the present application are described.

[0064] Reference Figure 5 In the first embodiment of the present application, the first material layer 110 to be connected includes a plurality of first material portions 119, and each first material portion 119 is respectively attached to a second material portion 129. In this embodiment, both the first material layer and the second material layer are sheet-like materials.

[0065] Reference Fig. 6A Before the connection is made, a clearance portion 112 is formed inside the first material layer 110. The clearance portion 112 can be formed by first cutting off a portion of the first material layer 110, and then attaching 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 cut off near the connection end to form the clearance portion 112. Therefore, each first material portion 119 forms a section 111 adjacent to each other, and the clearance portion 112 is formed between the multiple sections 111.

[0066] In this way, the two second material parts 129 of the second material layer 120 extend beyond the two first material parts 119 in the lateral direction. Therefore, it can be considered that each second material part 129 includes a bonding part 121 and a sheet structure 122 adjacent to each other, wherein the bonding part 121 is bonded to the first material layer 110 having the 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 hot melt adhesive, adhesive, or double-sided tape. Among them, the hot melt adhesive can be selected from one of PU hot melt adhesive, TPU hot melt adhesive, PS hot melt adhesive, and PA hot melt adhesive.

[0067] More specifically, each sheet structure 122 includes a connecting portion 123, a residual material portion 124, and a free end 125, wherein the connecting portion 123 is closer to the fitting portion 121 relative to the residual material portion 124, and the residual material portion 124 is between the connecting portion 123 and the free end 125. The connecting portion 123 is used to set the position of the connecting member 130, for example, the connecting member 130 is a suture, which is sewn to the position of the connecting portion 123 by manual or sewing, which will be described in detail below.

[0068] The depth H of the section 111 along the thickness direction of the first material portion 119 may be greater than or equal to the width T of the excess material portion 124 between the connecting portion 123 and the free end 125 to allow the excess material portion 124 to be accommodated in the clearance portion 112 , which will be described in detail below.

[0069] Reference Figure 6B , which shows another way of forming the clearance portion 112 inside the first material layer 110, that is, firstly laminating the first material layer 110 and the second material layer 120 together, and then cutting off a part of the first material layer 110. In this way, when the first material layer 110 and the second material layer 120 are difficult to be completely separated at the laminating part due to adhesive or other reasons, part of the first material part 119 may remain at the clearance portion 112, so that the first material part 119 forms a first thickness portion 119a and a second thickness portion 119b. The first thickness portion 119a corresponds to the uncut portion of the first material part 119, and the second thickness portion 119b corresponds to the cut portion of the first material part 119 (i.e., the clearance portion 112), and the second thickness of the second thickness portion 119b is less than the first thickness of the first thickness portion 119a. The sheet structure 122 of the second material part 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 and then a portion of the first material layer 110 is cut off, the connector 130 may be connected to the first material portion 119 before or after the cutting. Figure 6B After the two second material portions 129 are connected by the connecting portion 123, the remaining material portion 124 will be bent into the clearance portion 112. In some embodiments, the second thickness portion 119b (ie, the first material portion having the second thickness) abuts against the cross section 111 on at least one side of the clearance portion 112.

[0070] Reference Figure 7 The configuration of the connector 130 in the first embodiment of the present application is described. After forming the relief portion 112 in the first material layer 110 (for example, by Fig. 6A or Figure 6B The two ends of the cover 100 to be connected are brought close to each other, especially the sheet structures 122 of the two second material parts 129 are brought close to each other. At this time, 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 part 119b (see FIG. 119 ) that may be attached to the sheet structure 122 at the connecting part 123. Figure 6B ), for example, by sutures or rivets penetrating the two sheet structures 122 to connect the two second material portions 129.

[0071] Reference Figure 8After connecting the two second material parts 129, the cover 100 is turned over to cover the surface of the component 200, and the first material layer 110 is located inside the second material layer 120. At this time, the remaining material part 124 is accommodated in the clearance part 112 in the first material layer 110. More specifically, the remaining material part 124 is bent along the connecting member 130 and enters the clearance part 112. The remaining material part 124 can abut against the cross section 111 on at least one side of the clearance part 112. Since the depth H of the first material part 119 in the thickness direction is greater than or equal to the width T of the remaining material part 124 between the connecting part 123 and the free end 125 (see Fig. 6A and Figure 6B ), the excess material portion 124 does not extend inwardly beyond the inner side of the first material layer 110, and thus does not abut the surface of the component 200. Therefore, the cover 100 has a flat surface at the connection, and does not form a ridge R as in the prior art (see Figure 4 ).

[0072] It should be understood that Figure 8 The cover 100 is shown as being applied to a pipe or a rod, wherein the cover 100 is surrounded by a member 200 (see Figure 1 ), wherein the first material layer is formed by winding a sheet material into a cylindrical layer and covers the outer periphery of the component 200. However, the cover 100 of the present application can also be applied to Fig. 9 A panel is shown in which the covering 100 covers only one side of the component 200 .

[0073] Reference Figures 10 to 13 A covering 100 according to a second embodiment of the present application is described.

[0074] Reference Fig.10 , which shows a stereoscopic view of the first material layer 110 and a partially enlarged cross-sectional view of the stereoscopic view. In the second embodiment, the first material layer 110 is not formed by winding and connecting sheet materials, but is formed into a cylindrical structure in an integral molding manner. Fig.10 The portion of the cylindrical structure including the clearance portion 112 is shown. The clearance portion 112 is a recessed structure formed by molding the first material layer 110. Of course, in other embodiments, the clearance portion 112 can also be formed by cutting on the complete cylindrical structure, which is not limited here.

[0075] Reference Fig.11, similar to the first embodiment, the second material layer 120 includes two second material parts 129, each second material part 129 includes a sheet structure 122, and the two sheet structures 122 are connected at the connection part 123 by a connecting piece 130 to connect the two second material parts 129. Specifically, when the component 200 is a pipe or a rod, the inner side of the second material layer 120 is turned outward, and the sheet structures 122 of the two second material parts 129 are close to each other. Then, the connecting piece 130 connects the two sheet structures 122 at the connection part 123, for example, by sutures or rivets penetrating the two sheet structures 122 to connect the two second material parts 129, so as to form Fig.11 The second material layer 120 to be turned over is shown. Fig.12 ,Will Fig.11 After the second material layer 120 is turned back to face the inner side inward, it is covered on the outer side of the first material layer 110, so that the remaining material portion 124 of the second material layer 120 corresponds to the yielding portion 112 of the first material layer 110, thereby obtaining the covering 100. In this way, when the covering 100 covers the outer side of the component 200, the covering 100 can also have a flat surface at the connection.

[0076] It should be noted that, for the first material layer 110 of the cylindrical structure formed by an integral molding method in this embodiment, a 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 pasting methods such as double-sided tape). After the second material layer 120 is flipped and sleeved on the outside of the first material layer 110, the component 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 fit the first material layer 110 and the second material layer 120. 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 tape, so that the cover 100 will not slide or loosen on the component 200.

[0077] Reference Fig.13 The covering 100 according to the second embodiment can also be applied to a panel, wherein the covering 100 only covers one side of the component 200. It should be noted that in the above embodiments, the multiple second material portions 129 to be connected can be different edges of the same material sheet, or can be edges of different material sheets. For example, the edges of multiple small-area material sheets are connected to each other to form a large-area second material layer 120.

[0078] It should be noted that, in the covering 100 provided in the present application, the first material layer 110 and the second material layer 120 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 that the first material layer 110 and the second material layer 120 are indirectly bonded together.

[0079] The coverings of the various embodiments of the present application can be applied to various components, such as the armrest pipes or armrest rods of a vehicle, and the coverings are armrest covers covering the outside of the components. The vehicle is, for example, a baby carriage, but is not limited thereto. Fig.14 The example of a baby stroller is shown, and the component 200 can be a push handle on the upper part of the baby stroller for the caregiver to hold when pushing the baby stroller; the component 200 can also be a handrail in front of the seat of the baby stroller for the child to hold when sitting. The outer part of each component 200 can be covered with a cover 100. Fig.14 The component 200 of the baby stroller shown is in the shape of an elongated strip and extends in a curved manner, and is generally in a U-shape. The covering 100 covers the curved portions on both sides of the component 200 and the middle portion between the two curved portions.
