Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a coat, a filling component and a mattress. Background Art

[0002] Cribs and playpens are furniture designed for children to provide a safe, comfortable space for rest and play. These beds usually come with a mattress that can be placed at the bottom of the bed to support the child's weight and provide a comfortable sleeping environment. The design of the mattress is crucial to ensure the safety and comfort of the child.

[0003] When using a bed, the mattress board mainly provides support. However, the bed board is too hard and uneven. Using the bed board directly will affect the comfort level, so it is necessary to use it with a coat to improve the comfort level.

[0004] The bed board is the core part of the mattress, and the correctness of its installation is directly related to the overall performance of the mattress. In the related art, errors often occur during the installation of the bed board, especially the problem of installing the front and back sides upside down. This incorrect installation not only affects the aesthetics of the mattress, but more importantly, it will reduce the use effect of the mattress. After the bed board is installed upside down, the surface of the mattress may become uneven, which will not only affect the quality of children's sleep, but may also cause them to have accidents when turning over. In addition, the installation of the bed board upside down may also cause deformation of the internal structure of the mattress, accelerate the aging process of the mattress, and shorten its service life. What's more serious is that if the mattress is unstable due to the installation of the bed board upside down, children may fall off the bed while playing, causing accidental injuries.

[0050] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0051] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0052] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0053] In the related art, refer to Figure 1 The bed board is composed of a plurality of panels, which are respectively installed in the compartments of the outer cover to form a mattress 10. Errors often occur during the installation of the bed board, especially the problem of installing the front and back sides in reverse. Such incorrect installation not only affects the aesthetics of the mattress 10, but more importantly, it reduces the use effect of the mattress 10.

[0054] Reference below Figures 2 to 19 The outer cover 100, the filling component 200 and the mattress 10 according to the embodiment of the present invention are described. The outer cover 100 of the present invention is used to cover the filling component 200, and the outer wall of the filling component 200 is provided with a groove 220 extending inward. Figure 2 and Figure 3In some embodiments, the outer sleeve 100 includes a main body 110 and a limiting portion 120. The main body 110 has an inner cavity 130 for accommodating a filling component 200, and the limiting portion 120 is at least partially disposed in the inner cavity 130. The limiting portion 120 is connected to the main body 110. It can be understood that the limiting portion 120 is connected to the edge of the main body 110, and the limiting portion 120 can also be connected to other positions of the main body 110, as long as at least a portion of the limiting portion 120 is located in the inner cavity 130. After the filling component 200 is disposed in the inner cavity 130, at least a portion of the limiting portion 120 extends into the groove 220 of the filling component 200, that is, the limiting portion 120 and the groove 220 of the filling component 200 are aligned. Therefore, if the limiting part 120 fails to align with the groove 220 of the filling component 200, the limiting part 120 will stop the movement of the filling component 200, resulting in the filling component 200 being unable to be arranged in the inner cavity 130, so that the outer cover 100 of the utility model can prevent the filling component 200 from being reversely installed with the outer cover 100. In other words, only when the filling component 200 is correctly connected to the outer cover 100, that is, when the groove 220 of the filling component 200 and the limiting part 120 are aligned, can the filling component 200 be arranged in the outer cover 100 and the mattress can be used normally.

[0055] Reference Figure 2 and Figure 3 In some embodiments, the main body 110 includes a first wall and a second wall, and the edge of the first wall is connected to the edge of the second wall, so that the first wall and the second wall together define an inner cavity 130 with an opening. The filling component 200 moves from the opening of the inner cavity 130 to the bottom of the outer sleeve 100. During the movement of the filling component 200 to the bottom of the outer sleeve 100, the groove 220 of the filling component 200 and the limiting portion 120 of the outer sleeve 100 are aligned, and the groove 220 accommodates at least a portion of the limiting portion 120 to ensure that the filling component 200 can move smoothly to the bottom of the outer sleeve 100.

[0056] Reference Figure 2 In some embodiments, the first wall and the second wall can be a piece of cloth, or the first wall and the second wall can be composed of multiple pieces of cloth. In some embodiments, the first wall and the second wall are a piece of cloth, and the piece of cloth is folded to form two opposite surfaces, and the two oppositely arranged surfaces respectively constitute the first wall and the second wall. The edges of the first wall and the second wall at both ends of the fold are correspondingly sewn to form the main body 110 of the jacket 100. Figure 3In some embodiments, the first wall and the second wall are composed of multiple pieces of fabric, which are sewn together to serve as the structure of the outer coat 100. For example, the first wall is composed of a first piece of fabric, the second wall is composed of a second piece of fabric, and a third piece of fabric is connected to the first piece of fabric and the second piece of fabric respectively to serve as the bottom of the outer coat 100, so that multiple pieces of fabric constitute the outer coat 100 of the present invention.

[0057] It is understandable that, referring to Figure 2 and Figure 3 In some embodiments, the stopper 120 may be a bump. Fig.12 In some embodiments, the limiting portion 120 may also be a portion where the first wall and the second wall are combined together. For example, the first wall and the second wall are partially combined together by suturing with a pressing line (or suture line), and the sutured position of the first wall and the second wall serves as the limiting portion 120. The pressing line extends from the edge of the first wall and the second wall toward the opening of the outer jacket 100. In the process of the filling component 200 moving from the opening of the outer jacket 100 to the bottom wall of the outer jacket 100, the portion of the first wall and the second wall sutured by the pressing line provides a limiting effect on the movement of the filling component 200, that is, when the filling component 200 is correctly assembled, the pressing line suture of the outer jacket 100 extends into the groove 220 to realize the assembly of the filling component 200 and the outer jacket 100; when the filling component 200 is incorrectly assembled, the pressing line suture of the outer jacket 100 abuts against the end of the filling component 200, thereby blocking the movement of the filling component 200 toward the bottom wall of the outer jacket 100, thereby preventing the filling component 200 and the outer jacket 100 from being reversely assembled. In some embodiments, parts of the first wall and the second wall are bonded together by glue, and the bonding position of the first wall and the second wall serves as the limiting portion 120 .

[0058] Of course, it is understandable that in some embodiments, the compression stitching of the jacket 100 is located in the middle area of ​​the first wall and the second wall, and it is only necessary to meet the requirement that when the filling component 200 is correctly assembled on the jacket 100, the compression stitching of the jacket 100 is configured to extend into the groove 220 of the filling component 200 to align with the filling component 200. When the filling component 200 is incorrectly assembled on the jacket 100, the compression stitching of the jacket 100 stops the assembly of the filling component 200.

[0059] In some embodiments, the limiting portion 120 is connected to the first wall and the second wall, respectively. Specifically, the limiting portion 120 may be connected only to the first wall, the limiting portion 120 may be connected only to the second wall, or the limiting portion 120 may be connected to both the first wall and the second wall. For example, when the limiting portion 120 is only connected to the first wall body, the limiting portion 120 is connected to the surface of the first wall body facing the second wall body, and the limiting portion 120 is composed of a protrusion extending from the first wall body toward the second wall body; when the limiting portion 120 is only connected to the second wall body, the limiting portion 120 is connected to the surface of the second wall body facing the first wall body, and the limiting portion 120 is composed of a protrusion extending from the second wall body toward the first wall body; when the limiting portion 120 is simultaneously connected to the first wall body and the second wall body, the limiting portion 120 may be composed of a baffle connecting the first wall body and the second wall body at the same time, or the limiting portion 120 may be composed of a portion where the first wall body and the second wall body are bonded or sewn, so that the limiting portion 120 is configured so that the filling component 200 is arranged in the inner cavity 130 and at least partially extends into the groove 220.

[0060] In some embodiments, one end of the stopper 120 facing the filling component 200 is adapted to abut against the bottom wall of the groove 220. When the filling component 200 is disposed in the inner cavity 130, the end of the filling component 200 abuts against the bottom wall of the groove 220, thereby improving the compactness of the assembly of the filling component 200 and the outer sleeve 100, thereby improving the stability of the assembly.

[0061] Reference Figures 4 to 10 The embodiment of the second aspect of the present invention provides a filling component 200, and the filling component 200 is used to fill the outer jacket 100. The outer jacket 100 includes a main body 110 and a limiting portion 120, the main body 110 of the outer jacket 100 has an inner cavity 130 for accommodating components, the limiting portion 120 of the outer jacket 100 is at least partially located in the inner cavity 130, and the limiting portion 120 of the outer jacket 100 is connected to the main body 110. The outer wall of the filling component 200 of the present invention has a groove 220 extending inward, wherein the filling component 200 is configured to be arranged in the accommodating cavity, and the limiting portion 120 of the outer jacket 100 at least partially extends into the groove 220. The limiting portion 120 can prevent the filling component 200 from being reversely installed, and its principle has been described above and will not be repeated here.

[0062] Reference Figure 5In some embodiments, the filling component 200 is a sphere, the limiting portion 120 is a columnar protrusion, and the groove 220 is a positioning hole opened on the surface of the sphere and extending inward. It is understandable that the positioning hole in this case can pass through the sphere or only extend to the inside of the sphere, as long as the groove 220 avoids the limiting portion 120 when the filling component 200 and the outer jacket 100 are correctly assembled, so that the filling component 200 can be assembled with the outer jacket 100 smoothly; when the filling component 200 and the outer jacket 100 are incorrectly assembled, the limiting portion 120 stops the end of the filling component 200, so that the filling component 200 cannot be assembled with the outer jacket 100.

[0063] Reference Figures 6 to 10 It can be understood that, in some embodiments, the filling component 200 is plate-shaped. When the filling component 200 is plate-shaped, the groove 220 is a U-shaped structure opened at the edge of the filling component 200 and extending inward. Figure 7 In some embodiments, the groove 220 is a U-shaped groove, the groove depth H2 of the groove 220 ranges from 60 to 70 mm, and the diameter H1 of the groove 220 ranges from 10 to 20 mm. As a preferred embodiment, the groove depth H2 of the groove 220 is 65.89 mm, and the diameter H1 of the groove 220 is 15.14 mm. The shape of the groove 220 is set in this way, which is conducive to realizing that the groove 220 avoids the limiting portion 120, and at the same time, the rigidity of the filling component 200 can be ensured.

[0064] Reference Figures 6 to 10 In order to prevent the outer jacket 100 from being worn by the edges and corners of the plate-shaped filling component 200, in some embodiments, the edges and corners of the filling component 200 are set to arc chamfers 211. In some embodiments, the arc chamfer 211 is provided on the side of the filling component 200 where the groove 220 is provided. On the one hand, it can prevent the outer jacket 100 from being worn by the filling component 200 during the movement of the filling component 200 toward the bottom wall of the outer jacket 100 and the outer jacket 100 from being worn by the edges and corners after the filling component 200 is assembled on the outer jacket 100. On the other hand, it can distinguish the front end and the rear end of the filling component 200. Specifically, the arc chamfer 211 is provided at the front end of the filling component 200, and the arc chamfer 211 is not provided at the rear end. Of course, it is understandable that in some embodiments, in order to further distinguish whether the filling component 200 is assembled on the outer jacket 100 upside down, the arc chamfer 211 is only provided on the side of the filling component 200 located at the groove 220. For example, the groove 220 is opened on the front side of the filling component 200 (with Figure 7 The lower side of the paper is regarded as the front side of the filling component), and the groove 220 divides the filling component 200 into left and right sides (with Figure 7The left and right sides of the paper are regarded as the left and right sides of the filling component), then the arc chamfers 211 are all set on the left side of the filling component 200, or the arc chamfers 211 are all set on the right side of the filling component 200. The sizes of the through holes 212 can be uniform or different. The intervals of the through holes 212 can be uniformly set or randomly set. The shape of the through holes 212 can be circular, square, or any other shape to match the structure and aesthetics of the filling component 200.

[0065] Reference Figures 6 to 10 In some embodiments, the filling component 200 includes a plurality of through holes 212. The plurality of through holes 212 are arranged at intervals in the filling component 200. When the filling component 200 is in a plate shape, the plurality of through holes 212 all penetrate the filling component 200 along the thickness direction of the filling component 200. The filling component 200 is provided with the through holes 212, which is conducive to the ventilation of the filling component 200. Of course, it can be understood that the through holes 212 can also play a role in slowly releasing the deformation of the filling component 200 when the filling component 200 is deformed.

[0066] Reference Figure 6 and Figure 7 In some embodiments, the filling component 200 includes a filling body 210 and a reinforcing portion 230. The filling body 210 includes a groove 220, the groove 220 is U-shaped, the reinforcing portion 230 is connected to the filling body 210, the reinforcing portion 230 surrounds the groove 220, the filling body 210 is plate-shaped, and along the thickness direction of the filling body 210, the reinforcing portion 230 protrudes from the filling body 210. Specifically, the reinforcing portion 230 is a flange surrounding the groove 220. Since the filling body 210 is provided with the groove 220, the surrounding area of ​​the groove 220 is easily deformed after the filling body 210 is subjected to force for a long time (for example, a child lying on a mattress may cause the groove 220 to deform after a long period of static pressure on the filling body 210). The present application reinforces the structural rigidity of the filling body 210 by setting the reinforcing portion 230 to reduce the deformation of the filling component 200 at the U-shaped groove 220.

[0067] Reference Figure 6 and Figure 7 In some embodiments, the filling component 200 has a reinforcing rib 250. The filling component 200 has a first surface wall and a second surface wall arranged in the thickness direction, and the reinforcing rib 250 is arranged on the first surface wall, and / or the reinforcing rib 250 is arranged on the second surface wall. The two opposite surfaces of the filling component 200 in the thickness direction have the largest area and are most likely to bend. Providing the reinforcing rib 250 on the first surface wall and / or the second surface wall is conducive to improving the structural rigidity of the filling component 200.

[0068] In some embodiments, the filling component 200 is assembled with the outer cover 100 to form a mattress together, wherein the filling component 200 is configured as a bed board. Considering the practicality of the mattress 10, when the user uses the mattress 10, the side of the mattress 10 facing the user needs to be relatively flat to ensure user experience. Figure 6 and Figure 7 The reinforcing portion 230 of the bed board protruding from the outer edge of the groove 220 and the reinforcing rib 250 protruding from the panel are both arranged on the back side of the bed board (or the reverse side of the filling component), that is, the surface of the bed board facing away from the used side, so as to improve the flatness of the used side of the mattress 10 when the user uses the mattress 10, thereby improving the comfort of the mattress 10.

[0069] Reference Figure 8 and Fig. 9 In some embodiments, the filling component 200 further includes a recessed portion 240. The filling body 210 is plate-shaped, and the filling body 210 is provided with a reinforcement portion 230 around the groove 220. The recessed portion 240 is connected to the filling body 210. The recessed portion 240 is provided on the side of the filling component 200 away from the reinforcement portion 230, that is, the recessed portion 240 is located on the side of the filling component 200 facing the user (or called the front side of the filling component). Specifically, the recessed portion 240 is recessed along the thickness direction of the filling body 210, and the position of the recessed portion 240 corresponds to that of the reinforcement portion 230. The provision of the recessed portion 240 can prevent the reverse side of the reinforcement portion 230 from shrinking, and the reverse side of the reinforcement portion 230 is reduced in glue to form the recessed portion 240, thereby reducing shrinkage marks.

[0070] It is understandable that, referring to Figures 11 to 13 , the filling component 200 and the outer sleeve 100 are reversely installed, including the front and rear ends of the filling component 200 being reversely installed and the front and back sides of the filling component 200 being reversely installed. In the case where the front and rear ends of the filling component 200 are reversely installed, since the groove 220 is only located on one side of the filling component 200, and the opposite side of the filling component 200 is not provided with the groove 220, when the inverted filling component 200 is assembled with the outer sleeve 100, there is no groove 220 to avoid the limiting portion 120, and the limiting portion 120 will resist the movement of the filling component 200, thereby avoiding the reverse installation of the filling component 200 being reversed front and back.

[0071] For the reverse installation of the filling component 200 with the front and back turned upside down, in this case, the opening of the groove 220 is configured not to be in the middle of the edge of the filling component 200. Therefore, when the filling component 200 is assembled on the outer sleeve 100 after being reversed, the movement path of the groove 220 is different from the movement path of the filling component 200 when it is correctly assembled on the outer sleeve 100. Therefore, it is impossible to avoid the limit portion 120 through the groove 220. Therefore, the limit portion 120 will stop the movement of the filling component 200 with the front and back turned upside down, thereby avoiding the reverse installation of the filling component 200 with the front and back turned upside down. Specifically, the filling component 200 includes a filling body 210, and the filling body 210 is plate-shaped. The filling component 200 moves toward the outer sleeve 100 along the length direction and is finally accommodated in the inner cavity 130 of the outer sleeve 100. The plate-shaped filling body 210 is a rectangular structure, including two long sides and two short sides. The groove 220 is connected to the short sides of the filling body 210, and along the width direction of the filling body 210 (in Figure 7 The left and right directions of the paper are the width directions of the filling body 210, and the distances from the groove 220 to the two sides of the filling body 210 are not equal. With such a configuration, when the plate-shaped filling body 210 is assembled with the outer cover 100 in an incorrect manner with the front and back sides inverted, the movement track of the groove 220 is different from the movement track of the filling body 210 when it is assembled correctly, and the filling component 200 cannot avoid the limiting portion 120 through the groove 220, so that the limiting portion 120 will block the assembly of the filling component 200, so that such a configuration can prevent the filling component 200 and the outer cover 100 from being assembled in reverse.

[0072] It can be understood that, in some embodiments, the filling component 200 can be a plate (such as a wooden board or a plastic board), or the filling component 200 can be composed of a plurality of plates.

[0073] When the filling member 200 is a plate, refer to Figures 11 to 13 In the first embodiment, the limiting portion 120 is disposed on the bottom wall of the outer sleeve 100. Specifically, one end of the limiting portion 120 is connected to the edge of the first wall and the second wall opposite to the opening of the outer sleeve 100. After the filling component 200 moves from the opening of the main body 110 to the bottom wall and the filling component 200 is disposed in the inner cavity 130, the end of the filling component 200 abuts against the bottom wall of the outer sleeve 100, and the limiting portion 120 extends into the groove 220 to complete the assembly of the filling component 200 and the outer sleeve 100. How the limiting portion 120 prevents the filling component 200 from being reversely installed has been described above and will not be repeated here.

[0074] Reference Fig.14 In the second embodiment, the limiting portion 120 is disposed in the middle of the outer sleeve 100, and the groove 220 of the filling component 200 avoids the limiting portion 120 so that the filling component 200 can be smoothly installed in the outer sleeve 100. The limiting portion 120 blocks the filling component 200 to prevent the filling component 200 from being reversely installed.

[0075] When the filling member 200 is composed of a plurality of plates, refer to Fig.15 In the third embodiment, each plate body is inserted into the groove 220. The bottom wall of the outer sleeve 100 is provided with a plurality of limiting parts 120, and the grooves 220 correspond to the limiting parts 120 one by one. When each limiting part 120 is inserted into the groove 220, the filling component 200 is assembled with the outer sleeve 100. How the limiting part 120 prevents the filling component 200 from being reversely installed has been described above and will not be repeated here.

[0076] In some embodiments, only one of the multiple plates of the filling component 200 is provided with a groove 220. Fig.16 In the fourth embodiment, the limiting portion 120 is located on the bottom wall of the outer jacket 100. At this time, the plate with the groove 220 is assembled with the outer jacket 100 first, that is, the limiting portion 120 extends into the groove 220, and then the other plates can be assembled with the outer jacket 100. If the plate with the groove 220 is assembled with the outer jacket 100 incorrectly, the other plates cannot avoid the limiting portion 120 because they are not provided with the groove 220, so they cannot be assembled with the outer jacket 100. Therefore, the structure of this solution can prevent the reverse installation of the filling component 200 composed of multiple plates.

[0077] Reference Fig.17 In the fifth embodiment, the limiting portion 120 is located at the side wall of the outer jacket. At this time, the plate body with the groove 220 first moves from the opening of the inner cavity 130 toward the bottom wall of the outer jacket 100 until the end of the plate body abuts the bottom wall of the outer jacket 100. In this process, since the limiting portion 120 is arranged on the side wall of the outer jacket 100, the limiting portion 120 will not block the movement of the plate body toward the bottom wall of the outer jacket 100. After the plate body abuts the bottom wall of the outer jacket 100, it moves toward the side wall of the outer jacket 100 provided with the limiting portion 120 until the side of the plate body abuts the side wall of the outer jacket 100, and the limiting portion 120 extends into the groove 220. If the assembly of the plate body is incorrect, the limiting portion 120 will block the movement of the plate body toward the side of the outer jacket 100, resulting in the plate body being unable to fully match the outer jacket 100, so other plates cannot be fully installed in the outer jacket 100, thereby preventing the filling component 200 and the outer jacket 100 from being installed reversely.

[0078] Reference Fig.18 and Fig.19The third aspect of the utility model provides a mattress 10, which uses the above-mentioned filling component 200 and outer cover 100. The filling component 200 is configured as the bed board of the mattress 10, and the outer cover 100 is configured as the cloth cover of the mattress 10. The cloth cover is provided with a limiting portion 120, and the bed board is provided with a U-shaped groove 220. During the process of the bed board being installed into the cloth cover, the groove 220 avoids the limiting portion 120, that is, the limiting portion 120 is arranged in the groove 220, and the bed board can be smoothly installed into the cloth cover. When the bed board is assembled with the cloth cover in the wrong way, the limiting portion 120 of the cloth cover cannot extend into the groove 220, so the limiting portion 120 will resist the end of the bed board, resulting in the bed board being unable to be installed on the cloth cover, thereby preventing the bed board from being reversely installed.

[0079] Of course, it is understandable that Fig.18 In some embodiments, the mattress 10 of the present invention is placed at the bottom of the storage space of the bed (baby bed), so that children can play in the storage space of the bed or older children can lie down; Fig.19 In some embodiments, the bed (baby bed) is also used in conjunction with a hammock, and the storage space of the hammock can be used for a slightly smaller child to lie down. At this time, the mattress 10 of the utility model is placed at the bottom of the storage space of the hammock to improve the comfort of the hammock.

[0080] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
