Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of springs, in particular to a left-handed butterfly spring. Background Art
[0002] At present, the existing spring device is an open spring core that can be used to make mattresses or cushions. The characteristic of the open spring core is that it can distribute the force applied by the user more evenly than the pocket spring. That is, when using an open spring, the spring compression per unit area is greater than that of a pocket spring. The springs with an open spring core are connected together in a row by relative spring connection, so that the open spring core can extend in a row or column of open spring cores. The connection of the springs can be connected by twisting or winding the open ends of each spring. Therefore, this method does not require the use of non-woven fabrics.
[0003] On October 12, 2022, the applicant applied for a continuous spring body and a spring mattress with patent publication number CN218635670U. The spring mattress provided is composed of a number of continuous spring bodies arranged in an arrangement. There is no breakpoint in the middle of the continuous spring body, and the durability is better. By adopting a continuous spring body with a butterfly-shaped end, the support surface of the spring is larger. When the spring mattress is assembled into a mattress, the butterfly-shaped continuous spring body can perfectly avoid the protrusion of the end of the bed net. It can not only be used in mattresses with sponge frames, but also can be used to manufacture mattresses with non-sponge frames. After being assembled into a mattress, it has a certain elasticity and is also suitable for massage beds or similar mattress types that require bending; however, in actual applications, there is a problem with the continuous spring body. After the continuous spring body is buckled and installed on the bed net frame through the connecting part, there will be looseness between the continuous spring body and the bed net frame. During use, the end of the continuous spring body will be slightly pulled and moved, resulting in uneven force on the continuous spring body during use, affecting the comfort of the user.

[0019] like Figures 1 to 2A left-handed butterfly spring is shown, which is a continuous spring body 1 formed by bending a steel wire. The continuous spring body 1 includes a plurality of butterfly springs arranged in an array, and the butterfly spring includes a left spring body 11 and a right spring body 12. The left spring body 11 and the right spring body 12 are both composed of a compression coil 101 in the middle section and end coils 102 with diamond shapes at both ends, wherein one end of the end coil 102 is connected to the compression coil 101 to form a compression portion 103, and the other end extends out of the compression coil 101 to form a crossing portion 104, and adjacent crossing portions 104 are connected; it should be understood that the crossing portions 104 of the left spring body 11 and the right spring body 12 are located at the same end direction and are respectively placed at the front and rear sides, and the two crossing portions 104 are connected by a third wire end 108, so that the two end coils 102 are butterfly-shaped. Compared with most mattress springs, the continuous spring body 1 has no breakpoint in the middle and is more durable. The top and bottom ends of the continuous spring body 1 are both set to be butterfly-shaped, so that the support surface of the spring is larger and the comfort of the spring mattress is better.
[0020] Specifically, the compression coil 101 is arranged in a left-handed manner, and a connecting portion 105 is provided between the compression portion 103 and the crossing portion 104. The connecting portion 105 is arranged above the inner side of the compression coil 101, and the connecting portion 105 is in an outer arc-shaped structure with an arc radius of 16-19 mm;
[0021] It is important to know that reference Figure 3-4 , the continuous spring body 1 is arranged along the inner side of the bed net frame 2, the connecting part 105 on the left side of the continuous spring body 1 overlaps with the left side of the bed net frame 2, and the connecting part 105 on the right side of the continuous spring body 1 overlaps with the right side of the bed net frame 2, so that the connecting part 105 of the continuous spring body 1 facing the left side and the connecting part 105 facing the left side are respectively connected and buckled with the left and right sides of the bed net frame 2 through the fixing sleeve 3; to be precise, the connecting part 105 between the compression part 103 and the crossing part 104 is arranged above the inner side of the compression coil 101. When the connecting part 105 on the side is connected to the bed net frame 2, the compression coil 101 directly below it can provide better support for the edge of the spring mattress, and the connecting part 105 adopts an outer arc structure with an arc radius of 16-19mm. When the connecting part 105 and the bed net frame 2 are buckled through the fixing sleeve 3, the friction between the fixing sleeve 3 and the connecting part 105 can be increased to avoid loosening and deviation.
[0022] Specifically, the compression portion 103 and the crossing portion 104 are both in an outer arc-shaped structure with an arc radius of 10-12 mm. The compression portion 103 is connected to the connecting portion 105 through a first wire end 106, and the crossing portion 104 is connected to the connecting portion 105 through a second wire end 107. The angle between the first wire end 106 and the second wire end 107 is 137 degrees. This scheme enables the connecting portion 105 to be located above the inner side of the compression coil 101. After the connecting portion 105 and the bed net frame 2 are buckled through the fixing sleeve 3, the compression coil 101 overlaps with the bed net frame 2 or protrudes outside the bed net frame 2. Even if the user sleeps on the edge of the mattress, he can feel the same supporting force.
[0023] Specifically, the passing portion 104 of the left spring body 11 and the passing portion 104 of the right spring body 12 are connected via the third wire end 108 , and the included angle between the third wire end 108 and the second wire end 107 is 60 degrees.
[0024] Specifically, the crossing portion 104 of the left spring body 11 and the compression portion 103 of the right spring body 12 are on the same horizontal line, and the compression portion 103 of the left spring body 11 and the crossing portion 104 of the right spring body 12 are on the same horizontal line, so that the widths of the left spring body 11 and the right spring body 12 remain consistent.
[0025] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
