Description

TECHNICAL FIELD

[0001] The present application relates to the field of mattress manufacturing, and in particular to a pocketed spring bed net. BACKGROUND

[0002] Currently, there are two methods for manufacturing a pocketed spring bed net: one is to connect the cloth of multiple rows of spring strings in sequence by ultrasonic welding to form a whole bed net; and the other is to spray hot melt glue on the surface of the spring strings and then bond the multiple rows of spring strings in sequence to form a bed net. On the one hand, a whole bed net is composed of hundreds of pocketed springs, and if there is a broken pocket or a defect in the packaging of a pocketed spring, the whole bed net may be scrapped, resulting in waste of materials; on the other hand, the multiple rows of spring strings are bonded or welded in sequence to form a bed net, which is low in production efficiency. CONTENT OF THE UTILITY MODEL

[0003] Based on the above problems, the present application provides a pocketed spring bed net, which divides a whole bed net into multiple spring units, facilitates replacement of pocketed springs, and improves production efficiency.

[0004] The present application provides a pocketed spring bed net, comprising:

[0005] a plurality of side-by-side spring units, each of which comprises two rows of connected spring strings, and each row of the spring strings comprises multiple pocketed springs connected in sequence, and in each spring unit, an opening is arranged at a connecting position of the two rows of connected spring strings;

[0006] a fixing belt which passes through the opening to fix the multiple spring units.

[0007] According to some embodiments of the present application, the fixing belt is in the shape of a long strip.

[0008] According to some embodiments of the present application, the end of the fixing belt is connected to the spring unit.

[0009] According to some embodiments of the present application, the connection mode of the end of the fixing belt to the spring unit is at least one of ultrasonic welding, buttoning, and bundling.

[0010] According to some embodiments of the present application, the connection mode of the fixing belt is a combination of one or more of the following connection modes:

[0011] (1) the fixing belt is in the shape of a ring with both ends connected;

[0012] (2) the fixing belt is in the shape of a C, and the ends are fixed on the spring units at both ends, respectively;

[0013] (3) the fixing belt is in the shape of a snake, and the fixing belt is connected to the spring units at both ends at several positions.

[0014] According to some embodiments of this application, in each spring unit, the two rows of connected spring strings are connected by ultrasonic welding.

[0015] According to some embodiments of this application, the two rows of spring strings that make up the spring unit are connected by fabric between the springs, and there are two welds at the connection point. The opening is located between the two welds. The spring unit is welded at intervals so that there are at least four springs between two adjacent connection points on the spring unit.

[0016] According to some embodiments of this application, the fixing strap is made of non-woven fabric or cotton fabric.

[0017] According to some embodiments of this application, the fixing strap is provided with a plurality of pocket springs spaced apart along its length. The diameter of the pocket springs is smaller than the diameter of the springs in the spring string, and they are used to fill the gaps between the spring units.

[0018] The beneficial effects of the bagged spring mattress in this application are as follows:

[0019] Each spring unit is independent of the others. If a quality problem occurs in a spring unit, it can be replaced individually without affecting other spring units, thus avoiding waste of materials.

[0020] The spring units are bound together with fixing straps. Different spring units can contain springs of different specifications, making it easy to achieve soft and hard partitioning of the bed net.

[0021] Production efficiency is improved by binding multiple spring units together with a fixing strap. Attached Figure Description

[0034] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] like Figure 1 As shown, an embodiment of this application provides a pocket spring mattress 100, which includes a plurality of spring units 10 arranged side by side and a fixing strap 20, the fixing strap 20 serving to bind and fix the plurality of spring units 10.

[0036] like Figure 2 As shown, multiple spring units 10 are arranged sequentially. The number of spring units 10 is set according to requirements, for example, four spring units 10. The multiple spring units 10 are parallel to each other and their ends are flush.

[0037] like Figure 3 As shown, the spring string 11 includes a plurality of pocket springs 111 connected in sequence. Two rows of spring strings 11 are connected to form a spring unit 10. For example, the pocket springs 111 of the two rows of spring strings 11 are welded at intervals, and the pocket springs 111 located at the end of the first row of spring strings are connected to the pocket springs 111 at the end of the second row of spring strings to form a spring unit 10.

[0038] like Figure 4As shown, in each spring unit 10, an opening 12 is provided at the connection point of the two rows of spring strings 11. For example, the opening 12 is located on the fabric where the spring string 11 is connected to another row of spring strings 11. The shape of the opening 12 is set according to requirements; for example, the diameter of the opening 12 gradually decreases from the middle to both ends.

[0039] The fixing strap 20 passes through the openings 12 of the multiple spring units 10 to bind the multiple spring units 10 together. The fixing strap 20 serves to fix the multiple spring units 10 together.

[0040] In the bagged spring mattress 100 of this embodiment, each spring unit 10 is independent and is secured by a fixing strap 20. If a spring unit 10 malfunctions, it can be replaced individually without affecting other spring units. Different spring units 10 can contain springs of different specifications, facilitating the separation of firmness and softness in the mattress.

[0049] like Figure 5 As shown, in some embodiments, the two ends of the fixing strap 20 are respectively located on the spring units 10 at both ends. For example, there are multiple fixing straps 20, with the first end of each fixing strap 20 connected to the side wall of the spring module 10 at one end, and the second end of each fixing strap 20 connected to the side wall of the spring module 10 at the other end, and the fixing strap 20 is C-shaped.

[0050] like Figure 6 As shown, in some embodiments, the fixing strap 20 includes a first fixing strap 21 and a second fixing strap 22. The first fixing strap 21 is connected at its first end and the second end, and the first fixing strap 21 is loop-shaped. The first end and the second end of the second fixing strap 22 are respectively located on the spring units 10 at both ends, and the second fixing strap 22 is C-shaped.

[0051] like Figure 7 As shown, in some embodiments, the retaining strap 20 extends in a serpentine pattern. The retaining strap 20 is connected to the spring units 10 located at both ends at several points.

[0052] like Figure 8 As shown, in some embodiments, the fixing band 20 includes a connected annular band 23 and a serpentine band 24. Optionally, both ends of the serpentine band 24 are provided with annular bands 23. The annular band 23 is generally annular, and the serpentine band 24 extends in a serpentine shape. For example, the end of the annular band 23 passes through a plurality of openings 12 and is connected to the serpentine band 24, and the two ends of the annular band 23 are connected. The fixing band 20 is connected to the spring units 10 located at both ends at several points.

[0053] In some embodiments, the two rows of connected spring strings 11 in the spring unit 10 are connected by ultrasonic welding. For example, the fabric of one row of spring strings 11 is connected to the fabric of another row of spring strings 11 by ultrasonic welding.

[0054] like Figure 9 As shown, in some embodiments, the two rows of spring strings 11 constituting the spring unit 10 are connected by fabric between the springs, and there are two welds at the connection points, namely a first weld 13 and a second weld 14. An opening 12 is located between the first weld 13 and the second weld 14. The spring unit 10 is welded at intervals so that at least four springs are included between two adjacent connection points on the spring unit 10.

[0055] In some embodiments, the fixing strap 20 is made of non-woven fabric or cotton fabric.

[0056] like Figure 10 and Figure 11As shown, in some embodiments, the fixing strap 20 has a plurality of pocket springs 30 spaced apart along its length, the diameter of the pocket springs 30 being smaller than the diameter of the springs in the spring string 11. The pocket springs 30 are used to fill the gaps between adjacent spring units 10.
