Description

  The present invention relates to a mat body having practical effects such as formation of high bulkiness, good air permeability, elasticity, compression resistance, and easy folding.

  As shown in FIG. 1, the mat body 2 that is generally manufactured from resin cotton mainly has a plurality of layers of flat cotton nets 21 that overlap each other from the bottom to the top after the silking and carding. Is formed by polymerization. The thickness required for the mat body 2 is determined by the number of layers of the flat cotton net 21, and the thickness increases as the number of layers increases.

  However, the mat body 2 having such a configuration has the following drawbacks. First, when the mat body 2 formed by laminating the flat cotton net 21 into a layer and being polymerized in the lateral direction has too many layers to be polymerized in the form of the mat body 2, Hot air for drying does not penetrate evenly into each layer surface, and the mat body 2 has a poor standard shape, the entire structure is loosened, and the durability is low.

  Next, since the mat body 2 is formed by superposing a plurality of layers of flat cotton nets 21 so as to overlap each other from the bottom to the top, the structure has only a lateral structural strength. The structure in the longitudinal direction becomes relatively weak, and preferable bulkiness, elasticity and compression resistance cannot be obtained. In particular, when the mat body 2 is manufactured as a mattress and a person sleeps on the mat body 2, the mattress is subjected to pressure for a long period of time after being used for a certain period of time, thus reducing bulkiness, elasticity, and compression resistance. To do. Finally, since the bulkiness, elasticity and compression resistance of the entire mat body 2 are lost, improvement is awaited.

  2 and 3, when the mat body 2 is used as a mattress for a medical bed, the bottom surface and the top surface of the mat body 2 are parallel to each other along a vertical direction. A plurality of groove portions 22 having a certain height are formed by cutting the lower back and the back of the patient even when a patient who is incapacitated is in bed for a long time. Alternatively, when the patient's upper body is raised at a certain angle for a meal or the like, or the seat is in a sitting state, the angle of the entire medical bed is adjusted so that the mat body 2 can be bent to a necessary angle. provide.

  However, when the mat body 2 is first manufactured, after the mattress of a necessary size is manufactured at a time, the mat body 2 is parallel to the bottom surface and the top surface with a certain interval along the upright direction. A plurality of groove portions 22 having a certain height are formed by cutting the mat body 2 so that the mat body 2 is bent at a certain angle. The number of the cut groove portions 22 cannot be increased (generally, two). If the number of the groove portions 22 formed by cutting the original complete mat body 2 is large, the structure strength is affected. Therefore, improvement is required.

  Therefore, the present inventor considers that the above-mentioned drawbacks can be improved, and as a result of intensive studies, a high bulkiness is formed in the entire mat body, and good air permeability, elasticity, compression resistance, and easy folding are achieved. It came to devise the mat body which has a practical effect.

  The present invention has been made in consideration of the above circumstances, and in order to solve the above problems, the present invention mainly aims to provide a mat body.

  The present invention for solving the above-mentioned problems and achieving the above object is that the mat body according to the present invention is made of resin cotton, and two flat cotton nets installed along the horizontal direction, and the 2 It is composed of an upright cotton net in which bent portions overlapping in the upright direction are joined between two flat cotton nets. Moreover, the wavy folding groove | channel installed in parallel with a horizontal direction is provided in the top part and bottom face of the intermediate | middle stage of the mat body comprised with the above-mentioned member.

  The present invention has practical effects such as a high bulkiness formed on the mat body, good air permeability, elasticity, compression resistance, and easy folding.

It is a top view which shows the mat body of one conventional embodiment. It is an external appearance perspective view which shows the mat body of other conventional embodiments. It is the schematic which shows operation shown in FIG. It is an expanded view which shows the mat body which concerns on preferable embodiment of this invention. It is an external appearance perspective view which shows the combination shown in FIG. FIG. 3 is an external perspective view in which the mat body of the present invention is provided with a wavy fold groove in an intermediate stage. It is the elements on larger scale of the mat body of the present invention. It is the schematic which shows planar operation shown in FIG.

  Preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiment described below does not limit the contents of the present invention described in the claims of the utility model registration. In addition, all the configurations described below are not necessarily essential requirements of the present invention.

  Hereinafter, the mat body of the present invention will be described in more detail with reference to FIGS. The mat body 3 of the present invention is used for a general mattress, and particularly for a medical mattress that needs to be bent. An upright cotton made of resin cotton, in which a folded portion 321 overlapping in the upright direction is formed between two flat cotton nets 31 installed along the horizontal direction after the cotton net is opened and laid. Net 32 is coupled. There is a gap 322 between all the adjacent bent portions 321 of the upright cotton net 32, and the top and bottom surfaces of the intermediate stage of the mat body 3 composed of the above members are parallel to the horizontal direction. A plurality of wave-like folded grooves 33 to be installed are provided. The positions of the wavy fold grooves 33 provided on the upper surface and the wavy fold grooves 33 provided on the bottom surface are designed to be alternately arranged (see FIGS. 7 and 8), and the mat body 3 as a whole has high bulkiness. Good longitudinal and lateral structural strength, elasticity, high air permeability, and effects of being easily folded.

  For this reason, according to the present invention, the upright cotton net 32 to which the intermediate part is joined by the molding machine is first bent and overlapped in the upright direction to form a desired height and size. Next, the top and bottom ends are covered with a flat cotton net 31 in the horizontal direction and heated at an appropriate temperature, the fibers themselves melt and adhere to each other, and the flat cotton net 31 and the upright cotton net Between the bent portions 321 of the 32, the flat mat body 3 (see FIGS. 4 and 5) structure is formed. Thereafter, a heavy pressure is applied to the intermediate stage of the mat body 3 in parallel with a certain distance from the upper surface and the bottom surface, and the mat body 3 is heated at an appropriate temperature, and receives the heavy pressure of the bent cotton 321 and the bent cotton 321 of the upright cotton net 32. The fibers at the spots are melted again and stick to each other and solidify. A plurality of wavy fold grooves 33 are formed in the middle stage on the top and bottom surfaces of the mat body 3 so as to be parallel to the horizontal direction (see FIG. 6).

With the above structure form, the structure strength of the mat body 3 in the vertical and horizontal directions and the vertical direction becomes very strong, and a structure form in a three-dimensional space is formed, and the structure strength is greatly increased. In addition, it has the following advantages.
1. The upright cotton nets in which bent portions overlapping in the upright direction are formed are respectively coupled to flat cotton nets whose top ends and bottom ends are installed along the horizontal direction. As a result, when the mat body is actually folded up and down when the mat body is actually used, the entire mat body is torn apart at the folded portion overlapping the upright direction of the upright cotton net, and the integrity of the entire mat body Is preserved.
2. Upright cotton nets are formed with bent portions that overlap in the upright direction, moderate gaps are formed between the bent portions, and the entire mat body has high bulkiness, good elasticity, breathability, and compression Has resistance.
3. Since the upright cotton net is formed with a bent portion that overlaps in the upright direction, it can be manufactured with the thickness and height of the mat body required by the user only by changing the height of the bent portion. In particular, due to the modification of the height, the breathability and compression resistance are low as in the conventional mat body formed by laminating a flat cotton net in layers and polymerized in the lateral direction, and the standard form becomes defective. Disappears.
4). The upright cotton net formed with overlapping bent portions in the upright direction is joined to a flat cotton net installed in the horizontal direction on the upper surface and the bottom surface, respectively. A plurality of corrugated flutes are provided on the top and bottom surfaces of the intermediate stage so as to be parallel to the horizontal direction. In particular, the mat body can be bent without affecting the overall structural strength.

  As described above, the mat body according to the present invention is significantly different in structure from the conventional one, and the conventional mat body is layered and polymerized in the lateral direction, so that air permeability is lost and the structure is loosened. The disadvantages of low elasticity and compression resistance are completely solved. In addition, it has a very preferable structure and achieves practical effects such as high air permeability, good air permeability, elasticity, compression resistance, and easy folding.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
