Description

Technical Field

[0001] The invention relates to the technical field of mattresses, and in particular to a foldable mattress for converting between large and small beds. Background Art

[0002] Common structures of mattresses in the prior art are as follows: Figure 5 As shown, it includes a fabric layer 100 located on the outermost side, a support layer 300 composed of a spring bed net and a material with a certain hardness and wear resistance buckled on the spring bed net, a filling layer 200 located between the fabric layer 100 and the support layer 300, and a surrounding edge 400 for edge support around the mattress.

[0003] Mattresses are widely used in families and hotels as a daily necessity. In hotel rooms, according to the different needs of guests for the number and size of beds, most of them have two types of rooms: a king-size bed room with only one king-size bed and a twin-size bed room or standard room with two smaller beds. The contradiction between the rigidity of the hotel's settings and the flexibility of the needs often confuses the operators: for example, more standard rooms are needed during the peak tourist season and the peak period of conferences, while king-size beds are often needed when receiving individual guests. This constantly changing demand requires the hotel to be able to convert these two types of rooms, that is, the king-size bed room with a single king-size bed and the standard room with two small beds can be converted at any time. The biggest problem with the conversion of these two types of rooms is the mattress. In existing practice, hotels often use two methods to deal with it: first, simply merge two small beds into one king-size bed. The problem is that there are ridges and grooves between the two mattresses, which cannot meet the needs of guests; second, directly replace one large and two small mattresses. The problem is that not only is the cost of preparing two sets of mattresses higher, but the handling and storage of mattresses will also add a lot of manpower burden. In the prior art, there is no mattress that can meet the conversion requirement.

[0004] In the patent literature, for example, the authorization announcement number CN2566718Y, entitled a utility model of a folding mattress, discloses a technical solution of forming a standard mattress by sewing two small mattresses together through single-side wrapping. The folding mattress is mainly used for easy transportation and storage, without considering the practical function of the mattress. There are still many problems when it is directly used for converting between large and small beds in hotel rooms. Summary of the invention

[0005] In order to overcome the disadvantages of poor adaptability of mattresses in the prior art and inability to adapt to the conversion of large and small beds, the present invention proposes a foldable mattress for converting large and small beds, and its detailed technical solution is as follows:

[0006] A foldable mattress for converting between large and small beds comprises a first mattress and a second mattress which can be separated / stacked; the first mattress and the second mattress each comprise two inner cores which are adjacent and spaced apart, two peripheral fabric layers which respectively cover the side surfaces of the inner cores, two second fabric layers which are respectively sewn to one side of the two peripheral fabric layers and cover the lower bottom surface of the inner core, and a first fabric layer which covers the upper surfaces of the two inner cores and is sewn to the other side of the peripheral fabric layer.

[0007] Furthermore, the inner core includes a first filling layer in contact with the first fabric layer, a spring support layer located below the first filling layer, a surrounding frame connected to the side of the spring support layer, and a second filling layer located below the spring support layer and in contact with the second fabric layer.

[0008] Furthermore, the inner core also includes a surrounding edge filling layer located between the surrounding frame and the surrounding edge fabric layer.

[0009] Furthermore, the thickness of the inner core is 130 mm to 160 mm, the thickness of the spring support layer is 60 mm to 80 mm, and the thickness of the first filling layer and the second filling layer is 70 mm to 90 mm.

[0010] Furthermore, the first filling layer, the second filling layer and the surrounding filling layer are composed of fillers, and the fillers are one or more of sponge, latex, memory foam or cotton.

[0011] Furthermore, the frame is a rectangular frame structure formed by welding multiple steel bars, and the sides are formed by welding upper longitudinal steel bars, lower longitudinal steel bars and vertical steel bars; the upper longitudinal steel bars of the adjacent sides of the two frame frames are bent at 150 mm from both ends and welded to the lower longitudinal steel bars.

[0012] Furthermore, the two first filling layers of the first mattress have the same hardness; the two first filling layers of the second mattress have the same hardness and are different from the hardness of the first filling layer of the first mattress; the two second filling layers of the first mattress have different hardnesses, and the two second filling layers of the second mattress have different hardnesses.

[0013] According to any of the above embodiments, the present invention has at least the following beneficial effects: the utility model provides a foldable mattress for converting between large and small beds. When the first and second mattresses are unfolded and folded, they can be used as a large bed mattress. When the first and second mattresses are separated and folded, they can be used as two small bed mattresses. Moreover, the large bed mattress for unfolding and folding and the two small bed mattresses for separate and folding have soft and hard surfaces, which can quickly adapt to the conversion between large bed rooms and standard rooms in hotels and meet customers' choices of room types and mattress soft and hard surfaces.

[0014] In terms of structural design, the first and second mattresses each have two inner cores arranged at intervals, which are connected by sewing the surrounding fabric layer, the second fabric layer and the first fabric layer to realize the functions of unfolding, stacking or separating and folding the first and second mattresses; two filling layers totaling eight filling layers are arranged on each side of the four inner cores of the first and second mattresses, and different fillings are used in different filling layers to make different layers have different hardnesses, so that users can choose the corresponding mattress hardness according to their needs; the thickness of the mattress inner core will vary after being pressurized due to the different hardnesses of the filling layers, and by reasonably arranging two mattresses, four inner cores and eight filling layers According to the hardness of the layer, two softer layers and two harder layers are arranged on the left and right sides when the two mattresses are unfolded and stacked for use, so as to solve the problem of left and right height difference that may arise; the spring supporting layers in the inner cores of the first and second mattresses are surrounded by a frame made of steel bars. In order to solve the discomfort caused to the user by the ridge formed by the two longitudinal steel bars at the lower end of the first filling layer at the interval between the two frames when unfolded and stacked for use, and also to take into account the soft and collapsed feeling that may occur when people sit at the head of the bed, the two steel bars are folded at about 150mm at both ends and connected to the steel bars on the other side, and the steel bars at both ends are replaced with steel wires of appropriate specifications.

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] A foldable mattress for converting between large and small beds, such as Figure 1 As shown, the first mattress 210 and the second mattress 220 can be unfolded or folded. The first mattress 210 and the second mattress 220 can be unfolded and folded to form a mattress for a double bed room. Figure 6 As shown, the mattress can also be separated and folded to form a small bed room. Figure 7 shown.

[0032] In order to further enhance the user experience and meet the needs of different users, a plurality of contact surfaces of different hardness are provided on the first mattress 210 and the second mattress 220. Figure 3 As shown, the first mattress 210 includes a first A surface 210A with a soft top, a first B surface 210B with a soft bottom, and a first C surface 210C with a hard bottom; the second mattress 220 includes a second A surface 220A with a hard top, a second B surface 220B with a hard bottom, and a second C surface 220C with a soft bottom. The hardness of the contact surface is determined by the filling material of the mattress. In the design, the corresponding contact surfaces of the first mattress 210 and the second mattress 220 have different hardnesses.

[0033] The first mattress 210 and the second mattress 220 have the same structural composition, and the difference is that the filling materials of the filling layer constituting the contact surface are different in softness and hardness. Figure 4As shown, the first mattress 210 and the second mattress 220 each include two inner cores that are adjacent and spaced apart, a first fabric layer 211 located on the upper surfaces of the two inner cores and sewn together with the inner cores, two second fabric layers 217 located on the lower surfaces of the two inner cores, and two surrounding fabric layers 216 that cover the sides of the inner cores and are sewn together with the first fabric layer 211 and the second fabric layer 217. The inner core includes a second filling layer 215, a spring support layer 213, a first filling layer 212, and a surrounding frame 214 that surrounds the spring support layer 213, which are stacked in order from bottom to top. The first fabric layer 211 covers the upper surface of the first filling layer 212, the second fabric layer 217 is located below the second filling layer 215, and the surrounding fabric layer 216 covers the side of the surrounding frame 214. When the first fabric layer 211 is sewn together with the surrounding fabric layer 216, the interval between the two surrounding fabric layers 216 that are spaced apart and stand side by side needs to be reduced as much as possible to avoid a groove in the middle of the longitudinal direction when unfolded for use.

[0034] In order to make the first mattress 210 and the second mattress 220 have different contact surfaces of softness and hardness, the two first filling layers 212 of the first mattress 210 are in contact with the first fabric layer 211 and both use the same filling material, so that the first A surface 210A has the same softness and hardness; the two second filling layers 215 of the first mattress 210 use different filling materials, so that the first B surface 210B and the first C surface 210C have different softness and hardness.

[0035] The two first filling layers 212 of the second mattress 220 use filling materials different from those of the two filling layers of the first mattress 210, so that the first A surface 210A and the second A surface 220A have different hardness. The two second filling layers 215 of the second mattress 220 use filling materials different from those of the two second filling layers 215 of the first mattress 210, and have opposite hardnesses, that is, the first B surface 210B and the second B surface 220B have opposite hardnesses, and the first C surface 210C and the second C surface 220C have opposite hardnesses.

[0036] The first filling layer 212 and the second filling layer 215 can be made of one or more materials selected from sponge, latex, memory foam or palm, and a hard filling layer or a soft filling layer can be selected according to specific needs.

[0037] The frame 214 is a rectangular frame structure formed by welding a plurality of steel bars, which is used to support the edge of the mattress to prevent soft collapse. Its side is formed by welding the upper longitudinal steel bars, the lower longitudinal steel bars and the vertical steel bars. Since the first mattress 210 and the second mattress 220 are unfolded and overlapped when used as a large mattress, there are two adjacent frame 214 in the mattress, and the adjacent sides of the two frames are located exactly in the middle of the mattress. If a full enclosure design is adopted, the upper longitudinal steel bars on the adjacent sides of the two frames will form two convex ridges in the middle of the mattress. In order to eliminate the convex ridges, the upper longitudinal steel bars are bent down and broken at the adjacent sides of the two frame 214. More specifically, the upper longitudinal steel bars on the adjacent sides of the two frame 214 are bent down and broken at 150 mm from the two end sections, and are welded to the lower longitudinal steel bars to increase the support force near the head of the bed. After the optimization, the practical results of the utility model show that there is no convex feeling when the mattress is unfolded and folded to be used as a large bed mattress, and there is no soft feeling when the mattress is folded and used as a small bed mattress because the upper and lower overlapping surrounding frames still retain the upper and lower steel bars on the side where the steel bars are removed after folding.

[0038] To further increase the comfort of the first mattress 210 or the second mattress 220 when in use, Figure 5 As shown, a surrounding filling layer 218 is also provided between the surrounding frame 214 and the surrounding fabric layer 216. The surrounding filling layer 218 can be filled with cotton and sponge, and is mainly used to prevent the human body from contacting the spring support layer 213.

[0039] The size of the foldable mattress of the utility model needs to be customized according to the bed frame specifications provided by the demander. When used in a hotel, it needs to match the size of the customized hotel bed frame. More specifically, the length of the small bed frame in the standard room of the hotel is generally 1900mm-2100mm, and the width is generally 1100mm-1380mm. The length of the first mattress 210 and the second mattress 220 is made according to the length of the bed frame provided by the customer that can hold the mattress, and the width is made according to the total width of the two small bed frames provided by the customer.

[0040] The thickness of the foldable mattress takes into account the thickness of the existing mattress in the hotel and the height of the bed frame, and also takes into account the limitations of the process and materials in the thickness of the foldable mattress. More specifically, the inner core thickness of the first mattress 210 and the second mattress 220 is preferably about 150 mm, more specifically 130 mm to 160 mm; the thickness when stacked can be about 300 mm, more specifically 260 mm to 320 mm; the thickness of the spring support layer 213 is preferably about 70 mm, more specifically 60 mm to 80 mm; the thickness of the first filling layer 212 and the second filling layer 215 is preferably about 80 mm, more specifically 70 mm to 90 mm.

[0041] When the unfolding and folding mattress of the utility model is used, it needs to be matched with the bed frame: the specifications and styles of the two small bed frames are basically the same, and the frames on both sides of the bed frame cannot be raised, that is, the frames on both sides of the bed frame and the load-bearing bed board of the mattress on the bed frame need to be maintained on the same horizontal plane, so that the unfolded mattress can form a horizontal plane when placed on the two combined bed frames.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
