Description

[Detailed Description of the Invention] The present invention relates to an improvement of a spring mat for a bed, and aims to provide a spring mat that improves the installation stability of a group of coil springs and at the same time does not cause abnormal noise.

Conventionally, as shown in Fig. 1, upper and lower skin materials a, a
There is a type in which a large number of coil springs c are arranged in a row in both directions, and each coil spring c is placed in a tube bag d to eliminate the contact noise between the coil springs c. However, in this type of spring mat, since the coil spring c must be connected laterally, a guide wire e such as a string or steel wire is folded and stretched between the side skins b and b, and the guide wire e is placed between the guide wires e and e. I'm forcing you, but
If the guide wire e is tightened strongly, the folded portion e' will be squeezed and deformed as shown by the two-dot chain line due to the deformation of the side skin b during use, and the guide wire e will no longer be parallel to the coil. Since a part of the tube bag d is pushed between the spirals of the spring c, there is a problem in that the tube bag d is damaged and generates a contact noise.

The present invention was developed in view of the above problem, and the stability of the guide wire tensioning part is improved by providing a rigid fastening member that maintains a predetermined distance at the folded part of the side skin of the guide wire. The purpose is to provide spring mats.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a partially cutaway plan view of the pine, and FIG. 3 is a perspective view of the main part thereof. Reference numeral 1, 1 is an outer frame made of steel wire that forms the outer shape of the spring mat, and inner skin materials 2, 2 such as cloth, pads, etc. are stretched on the upper and lower surfaces of the outer frames 1, 1, and the inner skin material The outer surface of 2 is covered with skin materials 3, 3. Also, outer frame 1,
An inner skin material 4 is also stretched on the circumferential side between the spaces 1 and 4.
A side skin material 5 continuous from the skin material 3 is provided on the outer surface of the pine to cover the entire circumference of the pine. Both inner skin materials 2,
A large number of coil springs 6, 6, etc. are lined up vertically and horizontally in the direction of the mat surface between the two, elastically holding the mat surface, and each coil spring 6 is housed in a flexible cylinder bag 7 made of non-woven fabric or the like. . 8 again
is a guide wire stretched between the coil springs 6, 6, . It consists of strings or steel wires that are divided vertically and fastened horizontally. The guide wire 8 is continuously stretched by folding the inner skin material 4, and a rigid holding member 9 made of a hard synthetic resin or a metal plate is attached to each folded portion 8a of the inner skin material 4.
It is held in contact with the outer surface of. The holding member 9 has small holes 10, 10 formed at both ends of a long plate-like body at the same intervals as the vertical pitches of the coil springs 6, and guide wires 8 are inserted into the small holes 10, 10. The forward and backward lines of the folded portion 8a are inserted through the guide wire 8, and the guide wire 8 is stretched in parallel at an interval determined by the pitch between the small holes 10, 10.

The bed spring mat with the above structure has a series of coil springs 6, 6... that are securely connected in the lateral direction by guide wires 8, 8... stretched in the lateral direction of the mat, thereby preventing the springs from collapsing. Therefore, stable elasticity of the mat surface can be obtained. In addition, since a rigid holding member 9 is provided at the folded portion 8a of the guide wire 8, the pitch between the guide wires 8, 8 is ensured, and since the coil spring 6 is not caught, the tube bag 7 due to the guide wire 8 is secured.
The spring mat of the present invention not only has the characteristics that it can be comfortably used for a long period of time without causing wear and tear, etc. Since it is covered, the appearance of the pine is not impaired, and the practical effects of implementing the present invention are extremely large.

Claims (1)

[Scope of utility model registration request] In a spring mat consisting of a large number of coil springs each inserted into a flexible cylinder bag vertically and horizontally in the surface direction of the mat, a guide wire that stretches between the coil springs is stretched between the side inner skin materials of the mat. When doing so, a rigid holding member extending along the outer surface of the inner skin member is inserted and stretched in the folded portion of the guide wire, and the standing pitch of the coil spring is held by the pitch interval that engages both ends of the holding member. A spring mat for beds that is characterized by its ability to tighten.
