Description

Technical Field

[0001] The present application relates to the field of sleeping bags, and in particular to a fixing structure and a fixing method of a sleeping bag. Background Art

[0002] At present, sleeping bags will slide when used, which makes the sleeping bag uneven and affects the sleeping experience. In order to solve this problem, a fixed structure is generally set between the sleeping bag and the mattress, such as a connecting rope and a cloth cover. The traditional cloth cover contains four cloth pieces, which are generally set in the front, back, left and right parts of the sleeping bag, and are used to cover the front and back sides of the sleeping pad from top to bottom. Then, the cloth pieces are tightened by the connecting rope to wrap the sleeping pad around so that the sleeping bag is fixed on the sleeping pad and is not easy to slide.

[0003] However, the existing fixing structure has the following defects: the mattresses on the market are of different lengths, widths and heights, so the fixing structure of the traditional sleeping bag cannot adapt to all mattresses. During installation, the problem of insufficient or excessive length of the cloth pieces will cause the sleeping bag to be unable to be installed or to be installed loosely will occur. Therefore, there is an urgent need for a sleeping bag fixing structure that is easy to fix, has a wide range of adaptability, and is suitable for a variety of mattresses. Summary of the invention

[0004] One object of the present application is to provide a sleeping bag fixing structure that is convenient to fix, has a wide range of adaptability, and is suitable for a variety of mattresses.

[0005] Another object of the present application is to provide a fixing method that is convenient to fix, has a wide range of adaptability, and is applicable to a variety of mattresses.

[0006] In order to achieve the above objectives, the technical solution adopted in this application is:

[0007] A sleeping bag fixing structure, the fixing structure is suitable for fixing a sleeping bag body and a mattress, each side of the sleeping bag body extends outward to form a plurality of wrapping parts with mutually separated side sides, the wrapping parts are suitable for being folded along the side of the mattress and partially wrapping the mattress, a rope tube part is provided on the side of the wrapping part away from the sleeping bag body, the fixing structure also includes an adjustment connecting rope and an adjustment component, the adjustment connecting rope passes through each of the rope tube parts in turn to form a rope ring, the adjustment component is installed at the node of the rope ring, the adjustment component is suitable for tightening the adjustment connecting rope to form rope rings of different sizes to adapt to mattresses of different sizes, and finally fix the sleeping bag body and the mattress.

[0008] It is worth mentioning that the inner wall of the rope tube portion defines a rope tube cavity, and the adjustment connecting rope is suitable for passing through each rope tube cavity and each adjustment component in sequence to form a rope loop. The separation of the sides means that the sides of the wrapping portion are not connected together and are separated from each other. The adjustment component is a prior art and is a structure that can tighten the adjustment connecting rope. By controlling the adjustment component, the size and aspect ratio of the rope loop formed by the adjustment connecting rope can be controlled, so that it can adapt to different mattresses. The node of the rope loop refers to the turning point of the rope loop.

[0009] After research, the inventor found that the main reason why the traditional sleeping bag fixing structure cannot be installed or is installed unstably is that different mattresses have different aspect ratios and thicknesses, and because the wrapping part on the sleeping bag body cannot be adjusted in real time according to needs, the wrapping part tightened by the adjustable connecting rope cannot properly wrap the mattress. If the tightening force is too small, the mattress and the sleeping bag body are not fixed enough. If the tightening force is too large, the mattress is deformed due to the force exerted by the wrapping part on the mattress, so that the fixing surface of the sleeping bag body fixed on the mattress is no longer horizontal, resulting in a significant decrease in the comfort of the sleeping bag body when used.

[0010] If you want to control the wrapping part to adjust its length in real time according to the size of the mattress, its structure is relatively complex, difficult to implement, and costly, which does not meet the needs of the market. Further research has found that the sleeping bag body and the mattress are fixed by adjusting the connecting rope, mainly by tightening the connecting rope and forming a rope loop at the bottom of the mattress. Since the connecting rope is adjusted to run through the rope tube, the rope loop can limit the displacement of the sleeping bag body relative to the mattress. Although it is extremely difficult to adjust the size of the wrapping part, the size of the rope loop can be adjusted to achieve the same sleeping bag body for mattresses of different sizes.

[0011] Therefore, the inventor of the present application has developed a fixing structure for a sleeping bag, which has multiple rope tube parts and adjustment components arranged at the nodes of the rope rings. By adjusting the adjustment components, the purpose of adjusting the size of the rope rings can be achieved (the aspect ratio of the rope rings can also be adjusted), thereby satisfying the fixation of mattresses with different aspect ratios and different sizes on the market, thereby increasing the versatility of the fixing structure.

[0012] It is easy to understand that although the lengths of the wrapping part and the rope tube part do not change, by adjusting the adjustment component arranged at the node of the rope ring, the position of the connecting rope relative to the side of the mattress can be controlled, thereby controlling the position of the rope tube part relative to the side of the mattress, thereby controlling the width-to-length ratio and size of the rope ring composed of the rope tube part, thereby achieving adaptation to different mattresses.

[0013] The sides of the sleeping bag body extend outward to form a plurality of wrapping parts separated from each other. In actual use, the use of mattresses of different sizes and different width-to-length ratios can be further satisfied, so that the versatility of the fixed structure is further improved, and it is avoided that the wrapping parts interfere with each other due to the mutual connection of the sides, thereby affecting the use experience.

[0014] Further preferably, the adjustment component is an elastic buckle, the wrapping part is folded along the side of the mattress to form a folding line, and the folding line on each wrapping part is parallel to the axial direction of the rope tube part arranged on the same wrapping part. The elastic buckle is a prior art, and has two rope threading holes and an adjustment roller. The adjustment connecting rope is suitable for passing through one of the rope threading holes, and after turning around the adjustment roller, passing through the other rope threading hole. By pressing the elastic buckle, the function of controlling and adjusting the tightness of the connecting rope can be achieved.

[0015] More preferably, the number of the wrapping parts is four, and they extend respectively in four directions of the front, back, left and right of the sleeping bag body.

[0016] Further preferably, the adjustment connecting rope comprises an adjustment section and a tensioning section, each of the tensioning sections is suitable for connecting to form the rope loop, and a snap-on buckle tongue or a snap-on buckle body is provided on the adjustment section, and the snap-on buckle tongue and the snap-on buckle body are respectively arranged at the distal ends of the diagonally arranged adjustment components, and the snap-on buckle tongue and the snap-on buckle body are connected to the adjustment component through the adjustment connecting rope, and when in a locked state, the snap-on buckle tongue and the snap-on buckle body are snapped into each other, and the adjustment connecting rope is in a tensioned state.

[0017] Further preferably, each of the adjustment components is correspondingly provided with two limit clamps, and the adjustment connecting rope is suitable for passing through one of the limit clamps and the adjustment component, and then passing through the other limit clamp. The size of the limit clamp is larger than the adjustment component and smaller than the rope tube part, and the limit clamp is suitable for controlling the uniform distribution of tension along the adjustment connecting rope.

[0018] Further preferably, the adjusting connecting rope is connected to the rope tube portion; the adjusting connecting rope is an elastic rope; the adjusting connecting rope is a non-elastic drawstring.

[0019] A method for fixing a sleeping bag comprises the following steps:

[0020] S100. Fix the sleeping bag body on the mounting plane on the top of the mattress, and fold each wrapping portion along the side of the mattress;

[0021] S200. Tighten the connection rope through various adjustment components to form a rope loop that can fix the mattress and the sleeping bag body.

[0022] Further preferably, S100 further includes the following steps:

[0023] S101. By means of the adjustment component, the length of the adjustment connecting rope is adjusted in four directions, namely, front, back, left, and right, to change the size of the rope loop.

[0024] Further preferably, the method further includes the following steps: S300. respectively engaging the diagonally arranged engaging buckle tongue and engaging buckle body to put the adjusting connecting rope in a tensioned state.

[0025] Further preferably, the following steps are also included:

[0026] S400. The tension of the adjusting connecting rope is evenly distributed by adjusting the setting of the limit clamp.

[0027] Compared with the prior art, the beneficial effects of this application are:

[0028] (1) By adjusting the position of each adjustment component, the position and size of the rope loop formed by the connecting rope passing through the rope tube and the adjustment component are controlled and adjusted, thereby meeting the needs of fixing mattresses of different sizes and different width-to-length ratios, and expanding the scope of use of the connection structure, thereby further improving the versatility; each side of the sleeping bag body is extended outward to form a plurality of wrapping parts with mutually separated side edges, which can further meet the needs of mattresses of different sizes and different width-to-length ratios in actual use, thereby further improving the versatility of the fixing structure, and avoiding interference between the wrapping parts due to the mutual connection of the side edges, thereby affecting the use experience;

[0029] (2) The method for fixing the sleeping bag is easy to use. First, the wrapping part is folded to partially wrap the mattress, and then the rope rings of different sizes are controlled by controlling the adjustment component, which is convenient for adapting to mattresses of different sizes.

DETAILED DESCRIPTION

[0045] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0046] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0047] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0048] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0049] After research, the inventor found that the main reason why the traditional sleeping bag fixing structure cannot be installed or is installed unstably is that the length-width ratio and thickness of different mattresses 200 are different, and because the wrapping part 1 on the sleeping bag body 100 cannot be adjusted in real time according to needs, the wrapping part 1 tightened by the adjustable connecting rope 3 cannot properly wrap the mattress 200, and the tightening force is too small, resulting in insufficient fixation between the mattress 200 and the sleeping bag body 100. If the tightening force is too large, the mattress 200 is deformed due to the force exerted by the wrapping part 1 on the mattress 200, so that the fixing surface of the sleeping bag body 100 fixed on the mattress 200 is no longer horizontal, causing a significant decrease in the comfort of the sleeping bag body 100 when in use.

[0050] If the wrapping part 1 is to be controlled to adjust its length in real time according to the size of the mattress 200, its structure is relatively complex, difficult to implement, and costly, which does not meet the market demand. Further research has found that the sleeping bag body 100 and the mattress 200 are fixed by adjusting the connecting rope 3, mainly by tightening the connecting rope 3 and forming a rope ring 31 at the bottom of the mattress 200. Since the connecting rope 3 is adjusted to pass through the rope tube 11, the rope ring 31 can limit the displacement of the sleeping bag body 100 relative to the mattress 200. Although it is extremely difficult to adjust the size of the wrapping part 1, the same sleeping bag body 100 can be used for mattresses 200 of different sizes by adjusting the size of the rope ring 31.

[0051] Therefore, the inventor of the present application has developed a fixing structure for a sleeping bag, one embodiment of which is as follows: Figures 1 to 12 As shown, the fixing structure is suitable for fixing the sleeping bag body 100 and the mattress 200. The sides of the sleeping bag body 100 extend outward to form a plurality of wrapping parts 1 with separated sides. The wrapping part 1 is suitable for folding along the side of the mattress 200 and partially wrapping the mattress 200. A rope tube part 11 is provided on the side of the wrapping part 1 away from the sleeping bag body 100. The fixing structure also includes an adjusting connecting rope 3 and an adjusting component 2. The adjusting connecting rope 3 passes through each rope tube part 11 in turn to form a rope ring 31. The adjusting component 2 is installed at the node of the rope ring 31. The adjusting component 2 is suitable for tightening the adjusting connecting rope 3, thereby forming rope rings 31 of different sizes to adapt to mattresses 200 of different sizes, and finally fixing the sleeping bag body 100 and the mattress 200.

[0052] The inventor has also developed a method for fixing a sleeping bag, comprising the following steps:

[0053] S100. The sleeping bag body 100 is fixed on the mounting plane at the top of the mattress 200, and each wrapping portion is folded along the side of the mattress 200;

[0054] S101. By adjusting the assembly 2, the length of the connecting rope 3 is adjusted along the front, back, left, and right directions to change the size of the rope ring 31;

[0055] S200 . Tighten and adjust the connecting rope 3 through each adjustment assembly 2 to form a rope loop 31 capable of fixing the mattress 200 and the sleeping bag body 100 .

[0056] S300. Respectively engage the diagonally arranged engaging buckle tongue 41 and engaging buckle body 42 to put the adjustment connecting rope 3 in a tensioned state.

[0057] S400. Adjust the setting of the limit clamp 5 to make the tension of the connection rope 3 evenly distributed.

[0058] It is worth mentioning that Figure 4 As shown, the inner wall of the rope tube portion 11 defines a rope tube cavity 111, and the adjustment connecting rope 3 is suitable for sequentially passing through each rope tube cavity 111 and each adjustment component 2 to form a rope loop 31. The side edges are separated from each other, which means that the side edges of the wrapping portion 1 are not connected together and are separated from each other. The adjustment component 2 is a prior art structure that can tighten the adjustment connecting rope 3. By controlling the adjustment component 2, the size and aspect ratio of the rope loop formed by the adjustment connecting rope 3 can be controlled, so that it can adapt to different mattresses 200; Figure 8 As shown, the adjustment connecting rope 3 passing through the adjustment assembly 2 is divided into an adjustment section 32 and a tensioning section 33, and each tensioning section 33 is connected to form a complete rope loop 31 as shown in FIG. Figure 5b and 6bAs shown, in this specific embodiment, the diagonal tensioning sections 33 are connected to each other to form a cross structure (such as Figure 5b and 6b The node of the rope ring 31 refers to the turning point of the rope ring 31.

[0059] In this specific embodiment, Figure 5a and Figure 6a Two mattresses 200 of different sizes are shown, and the sleeping bag body 100 is fixed to the mattress 200 by a fixing structure; Figure 5b and Figure 6b It is respectively demonstrated that by controlling the tightening of the adjustment component 2, the adjustment connecting rope 3 is coordinated with the rope tube portion 11 and the adjustment component 2 to form rope loops 31 of different sizes (length-width ratios), thereby achieving the purpose of fixing mattresses 200 of different sizes (length-width ratios).

[0060] The fixing structure of the sleeping bag comprises a plurality of rope tubes 11 and rope rings 31 arranged at the nodes of the adjusting components 2 (in this specific embodiment, as shown in FIG. Figure 5b The node of the rope ring 31 is located between two adjacent rope tube parts 11), and the purpose of adjusting the size of the rope ring 31 can be achieved by adjusting the adjustment component 2 (the aspect ratio of the rope ring 31 can also be adjusted), so as to meet the fixation of mattresses 200 with different aspect ratios and different sizes on the market, thereby increasing the versatility of the fixing structure.

[0061] It is easy to understand that although the lengths of the wrapping portion 1 and the rope tube portion 11 do not change, the position of the connecting rope 3 relative to the side of the mattress 200 can be controlled by adjusting the adjustment assembly 2 at the node of the rope ring 31 (e.g. Figure 5b and Figure 6b As shown, the position of the side of the mattress 200 is shown by the dotted line), thereby controlling the position of the rope tube portion 11 relative to the side of the mattress 200, thereby controlling the width-to-length ratio and size of the rope ring 31 composed of the rope tube portion 11, thereby achieving adaptation to different mattresses 200.

[0062] The sides of the sleeping bag body 100 extend outward to form a plurality of wrapping parts 1 separated from each other. In actual use, the use of mattresses 200 of different sizes and different width-to-length ratios can be further satisfied, thereby further improving the versatility of the fixing structure and avoiding interference between the wrapping parts 1 due to the interconnected sides, which affects the use experience.

[0063] Further preferably, Figure 2 and Figure 7As shown, the adjustment component 2 is an elastic buckle, and the wrapping portion 1 is folded along the side of the mattress 200 to form a folding line 12. The folding line 12 on each wrapping portion 1 is parallel to the axial direction of the rope tube portion 11 arranged on the same wrapping portion 1. The elastic buckle is a prior art, and has two rope holes and an adjustment roller. The adjustment connecting rope 3 is suitable for passing through one of the rope holes, and after being flipped around the adjustment roller, it passes through the other rope hole. By pressing the elastic buckle, the tightness of the connection rope 3 can be controlled. In addition, the folding line 12 is a virtual line. In order to adapt to different sizes of mattresses 200, the position of the folding line 12 on the wrapping portion 1 is not fixed. Figure 7 As shown, a folding line A121 and a folding line B122 are shown, wherein the folding line B122 is arranged outside the folding line A121.

[0064] Making the folding line 12 on each wrapping portion 1 parallel to the axial direction of the rope tube portion 11 arranged on the same wrapping portion 1 can reduce the length of the adjustment connecting rope 3 required and make the virtual figure formed by each rope tube portion 11 similar to the shape of the mattress 200, thereby achieving a better fixing effect.

[0065] Further preferably, Figure 7 As shown, there are four wrapping parts 1 , which extend along four directions of the sleeping bag body 100 , namely, front, back, left, and right.

[0066] In order to reduce material and processing costs, and reduce processing time, and the shape of the conventional mattress 200 is generally rectangular, the number and position of the wrapping part 1 are further optimized, so that it extends along the four directions of the front, back, left, and right of the sleeping bag body 100, thereby reducing the number of wrapping parts 1 required, reducing processing time, and further optimizing costs. The wrapping part 1 extending along the four directions of the front, back, left, and right of the sleeping bag body 100, the connection line between the wrapping part 1 and the sleeping bag body 100 is parallel to the side of the mattress 200, so that while meeting the fixing requirements, the material saving effect is the best.

[0067] Further preferably, Figure 3 , Fig.10 and Fig.11 As shown, the distal ends of the diagonally arranged adjustment components 2 are respectively connected with a snap-on buckle tongue 41 and a snap-on buckle body 42, which are connected to the adjustment component 2 via the adjustment connecting rope 3. When in the locked state, the snap-on buckle tongue 41 and the snap-on buckle body 42 are snap-on with each other, and the adjustment connecting rope 3 is in a tensioned state. Figure 8As shown, the distal end of the adjustment component 2 is a position away from the adjustment component 2, and the snap-on buckle tongue 41 and the adjustment component 2, as well as the snap-on buckle body 42 and the adjustment component 2 are respectively connected through the adjustment connecting rope 3. The adjustment connecting rope 3 includes an adjustment section 32 and a tensioning section 33, each tensioning section 33 is suitable for connecting to form a rope ring 31, and the adjustment section 32 is provided with a snap-on buckle tongue 41 or a snap-on buckle body 42, and the snap-on buckle tongue 41 and the snap-on buckle body 42 are respectively arranged at the distal end of the adjustment component arranged diagonally.

[0068] When in the locked state, the snap-fit ​​buckle tongue 41 and the snap-fit ​​buckle body 42 are snap-fitted to each other to form a snap-fit ​​buckle structure 4 (such as Figure 3 In order to improve the fixing effect of the sleeping bag body 100, the adjusting sections 32 of the tightened adjusting connecting rope 3 are connected to form a cross state, so that the sleeping bag body 100 can adapt to mattresses 200 of different sizes and the fixing effect is good.

[0069] Further preferably, Figure 2 As shown, each adjustment component 2 is correspondingly provided with two limit clamps 5, and the adjustment connecting rope 3 is suitable for passing through one of the limit clamps 5 and the adjustment component 2, and then passing through the other limit clamp 5 (that is, the two limit clamps 5 are both arranged on the tensioning section 33). The size of the limit clamp 5 is larger than the adjustment component 2 and smaller than the rope tube part 11. The limit clamp 5 is suitable for controlling the uniform distribution of tension along the adjustment connecting rope 3.

[0070] The size of the limit clip 5 is larger than the adjustment component 2 and smaller than the rope tube 11, which can limit the displacement of the limit clip 5 to the adjustment section 32, and can also be inserted into the rope tube 11 to hide it, thereby improving the surface aesthetics. In addition, two limit clips 5 are provided for each adjustment component 2, which can simultaneously control the tension of the adjustment connecting rope 3 entering and exiting the adjustment component 2, so that the tension along the adjustment connecting rope 3 is evenly distributed.

[0071] Further preferably, the rope tube portion 11 is lined with a webbing, and the webbing is suitable for controlling and adjusting the wear of the rope tube portion 11 caused by the connecting rope 3 .

[0072] The provision of the webbing can effectively reduce the wear of the adjusting connecting rope 3 on the rope tube portion 11, thereby increasing the service life of the entire fixing structure.

[0073] Further preferably, Fig.12 As shown, the connection rope 3 is adjusted to be connected to the rope tube 11 by a screw connection, and a screw connection structure 6 is formed. The screw connection is a prior art in the art, which can make the position of the connection rope 3 in the rope tube 11 relatively fixed, reduce wear, and thus increase the service life of the fixed connection structure.

[0074] Preferably, the adjusting connecting rope 3 is an elastic rope, which can more conveniently control the uniform distribution of tension along the adjusting connecting rope 3 and more easily control the size of the rope ring 31.

[0075] Preferably, the adjustment connecting rope 3 is a non-elastic drawstring, which has a lower cost and is more conducive to reducing costs and increasing product profits. In addition, since the adjustment component 2 is provided, the size of the rope ring 31 can also be controlled.
