Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an underlay mat for OA equipment, and more particularly, to an underlay mat that can be laid under the OA equipment, for example, to facilitate horizontal movement of the equipment on a desk.

[0002] The "OA equipment" used here is mainly used on a desk, such as a notebook computer, a desk computer, a laptop word processor, a desk word processor, a printer, an image input device, a copying machine, a facsimile machine, and the like. If the hard disk and the display are separated, such as a desk-type personal computer or a desk-type word processor, which means a device, the mat of the present invention is laid under both or one of them.

[0003]

[Problems to be solved by conventional technology and device]

 Conventionally, there have been the following inconveniences when working (working) with a notebook computer placed on a desk, for example.

[0004] That is, when a notebook PC is not used, it is usually placed at the back of the desk or on the side of the desk, and when used, the PC is horizontally moved on the desk to near the hand. Despite the recent reduction in weight, the above-mentioned movement while sitting in a chair required a certain amount of arm power, which forced a burdensome task. In particular, when a rubber mat (desk mat) was laid almost all over the desk, the above-mentioned movement of the personal computer was a troublesome task due to the increased frictional resistance.

[0005] Incidentally, the force required to move the notebook computer (3.5 kg in weight) on a desk is about 5 to 6 kg, and the force required to move a laptop word processor (6.5 kg in weight) on a desk. The required force is 10kg or more (exceeds the measurement limit, and details cannot be measured).

In addition, when the position of a desk-type personal computer is changed on a desk, it is difficult to move the personal computer because of its heavy weight, which requires a rather cumbersome operation. [Purpose of the Invention] The present invention has been made in view of the above-mentioned circumstances, and the purpose of the invention is to make it possible to use a desk mat even when sitting on a chair and laying a rubber mat (desk mat) almost all over the desk. An object of the present invention is to provide an underlay mat that can easily move (horizontally move) an OA device such as a notebook computer placed on a mat.

[0007]

[Means for Solving the Problems]

 An underlay mat for OA equipment according to claim 1, wherein the underlay mat on which the OA equipment is mounted and which facilitates horizontal movement of the OA equipment, for example, on a desk, is provided on a lower surface of a rubber sheet or a soft synthetic resin sheet. , A woven sheet or a knitted sheet.

The underlay mat for OA equipment according to claim 2 is an underlay mat on which the OA equipment is placed to facilitate horizontal movement of the OA equipment, for example, on a desk, and a rubber sheet or a soft synthetic resin sheet. A non-woven fabric is adhered to the lower surface of the non-woven fabric.

The underlay mat for OA equipment according to claim 3, which is an underlay mat on which the OA equipment is placed to facilitate horizontal movement of the OA equipment, for example, on a desk, wherein a rubber sheet or a soft synthetic resin sheet is used. A large number of short fibers are planted on the lower surface of this.

The underlay mat for an OA device according to claim 4, wherein the underlay mat on which the OA device is mounted and which facilitates horizontal movement of the OA device, for example, on a desk, is provided. A rubber sheet or a soft synthetic resin sheet An embossed plastic sheet or an embossed pulp sheet is adhered to the lower surface of the pulp sheet. The underlay mat for OA equipment according to claim 5, wherein the underlay mat on which the OA equipment is placed and which facilitates horizontal movement of the OA equipment, for example, on a desk, is made of a double-rassel knitted mat. It is.

[0011]

[Action]

 The underlay mat according to the present invention is laid on a desk, for example, and an OA device such as a notebook computer is placed thereon (that is, on the sheet-like material). At this time, when the lower surface of the underlay mat is viewed microscopically, as shown in FIG. 2 or FIG. 4, point contact is made with the upper surface of the desk. This makes it possible to minimize the frictional resistance between the underlay mat and the desk when moving the OA apparatus together with the underlay mat, thereby facilitating the horizontal movement of the OA apparatus on the desk. Therefore, even if a rubber mat (desk mat) is laid on the desk, it does not hinder horizontal movement of the OA equipment on the desk.

Further, as described above, since the sheet-like material is made of a soft synthetic resin foam sheet or a rubber sheet, it is possible to suppress a positional shift between the OA device and the underlay mat during movement of the OA device. . The underlaying mat according to claim 5 does not have a sheet-like material, but since the mat itself is made of a relatively thick double-rassell-knitted mat, an action similar to that of the sheet-like material is achieved. It works.

[0013]

[Embodiment of the invention]

 Examples of the sheet-like material that can be used in the present invention include foamed or non-foamed synthetic resin sheets (vinyl chloride resin, polyamide resin (nylon resin), polyester resin, polycarbonate resin, silicon resin, urethane resin, A sheet made of an acrylic resin or the like), a rubber sheet (a sheet made of SBR, NBR, BR, silicon rubber, fluorine rubber, urethane rubber, or the like), and the like. The use of a rubber sheet improves the adhesion between the sheet and the OA device, and when the OA device is moved, there is no possibility that the device slides on the sheet and only the OA device moves. Good.

The thickness of the sheet is preferably 0.1 to 1.0 cm. If it is less than 0.1 cm, problems such as breakage are apt to occur unfavorably in terms of mechanical strength. On the other hand, if it exceeds 1.0 cm, it is not preferable in terms of changing the feeling of use of the device placed thereon and the stability of the device.

The types of fibers used for the woven sheet, the knitted sheet, and the nonwoven fabric are not particularly limited, and specific examples include the following materials. That is, examples of plant fibers include seed hair fibers (cotton, kapok cotton, etc.), bast fibers (flax, cannabis, etc.), vein fibers (manila hemp, sisal hemp, etc.), fruit fibers (coconut fiber, etc.). Examples of animal fibers include silk, animal hair fibers (wool, goat wool [cashmere hair, mohair, etc.]), horsehair, and the like; mineral fibers include asbestos; and regenerated artificial fibers include: Viscose rayon, cupra rayon, acetate, and the like. Synthetic fibers include polyamide fibers (nylon), polyester fibers, polyurethane fibers, polypropylene fibers, polyethylene fibers, polyvinyl chloride fibers, and polyvinyl chloride fibers. Examples include vinylidene fibers, polyvinyl alcohol fibers (vinylon), and polyacryl fibers.

When a woven sheet is used, the weaving method may be plain weave (suede, flat crepe, crepe desin, wall crepe, georgette, broad cloth, taffeta, etc.), oblique weave [twill weave] (slake, denim) , Ticking, shurrers, tweed, tartan check, etc.), satin weave (italian cloth, satin back, etc.), wool weave (bell bed, velveteen etc.), but not limited to these.

In the case of using a knitted fabric sheet (mat), there is no limitation on the knitting method. Knitting, pile knitting, tricot knitting, overcast knitting, and the like.

It is preferable that the short fibers have a strength to maintain a substantially upright state at least in a state where the OA device is placed on the sheet-like material. For example, nylon fiber, rayon fiber, polyester fiber, bennylon fiber, acrylic fiber and the like can be mentioned. The length of the short fibers is preferably 0.2 to 5 mm. If the thickness is less than 0.2 mm, not only is it difficult to plant, but also because of the weight of the equipment placed on top, the lower surface of the sheet-like object may abut the upper surface of the desk, and the effect of the present invention is It may be difficult to demonstrate. In addition, when the length exceeds 5 mm, when the device is placed, the fibers are bent by the weight of the device, and the fibers do not make point contact with the desk, so that the effect of the present invention is hardly exerted as described above. . The thickness of the short fibers is preferably 0.5 to 70 denier.

The above-mentioned short fibers may be directly planted on the lower surface of the sheet-like material, or may be planted as follows within the scope of the present invention. That is, a large number of short fibers are implanted in advance through a binder on the lower surface side of a sheet-like nonwoven fabric or knitted sheet (hereinafter, referred to as “intermediate sheet material”). It is preferable to bond the sheet-like materials by bonding, welding or the like. In this case, the nonwoven fabric used has a basis weight of 50 to 200 g / m ² , the woven fabric sheet has a length and width of 80 / inch, and the knitted fabric sheet has a count of 30 / 15F 28 gauge or more. It is preferable to use

The underlay mat of the present invention includes those using a woven sheet, a knitted sheet, a nonwoven fabric, or those in which short fibers are planted and which are embossed. Of course, in this case, a woven sheet, a knitted sheet, and a nonwoven fabric are stuck so that the surface on which the unevenness is formed by the embossing treatment is the opposite side to the sheet-like material, that is, the lower surface of the underlay mat.
