Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a desk mat with an anti-slip suitable for a tilting top plate such as a writing bureau type desk top plate or an inclined top plate of a drawing table.

2. Description of the Related Art Conventionally, in a general desk where a top plate such as an office desk is fixed in a horizontal state, a flexible sheet made of synthetic resin or synthetic rubber or a flexible sheet made of transparent synthetic resin is used. Desk sheets made of a combination of felt and Racha fiber base sheets are widely used. Further, in this desk sheet, since the positional displacement is prevented by the frictional resistance of the desk sheet, it is rare to provide a special anti-slip.

However, for desks such as a writing bureau type desk where the tabletop is vertically or steeply raised when not in use, the above ordinary desk mat will slide down when the tabletop stands up. Therefore, it is necessary to re-lay the mat each time it is used and remove it when not in use to store it. In addition, the above-mentioned desk mat cannot be used on an inclined top plate such as a drawing table because the desk mat slides down.

Therefore, as the desk mat for the tilting type top plate or the tilted top plate, it is necessary to fix it to the top plate itself in advance, or to prevent it from slipping with an adhesive tape, a push pin, a rubber magnet or the like.

However, in the method of fixing the desk mat to the top plate,
In addition to being difficult to replace when damaged, it requires a special fixing structure, resulting in high cost, and it cannot be applied to existing tilting tops or tilting tops. On the other hand, in the case where the adhesive tape is adhered to the back surface of the mat, the tape surface is sticky, and the adhesive agent is easily transferred to the surface of the top plate and easily soiled.
There is a drawback that the sticking property is reduced in a short period of time due to the adhesion and deterioration of dust. Further, there is a problem that the top plate is damaged by fixing with the push pin, and the rubber magnet can be used only for the top plate having the magnetic metal on the surface.

In view of the above-mentioned circumstances, the present invention is capable of firmly adhering to the surface of the tilting top plate or the tilted top plate due to the adsorptivity of the mat itself and is detachable, and is non-greasy. It is an object of the present invention to provide a desk mat which does not have a risk of being soiled or damaged and which has no appropriate difference depending on the material of the top plate.

Means for Solving the Problems In order to achieve the above object, a desk mat according to the present invention has a non-slip member made of a soft synthetic resin foam layer fixed to at least a part of a back surface side of a flexible mat body. In addition, the foam layer of the non-slip material is a foam of closed cells having a foaming ratio of 2 to 10 times and cells distributed in a range of a diameter of 0.01 to 1 mm, and the surface of the non-slip material is The cut surface of the foam body is characterized in that a large number of minute suction cups formed by open cells are formed as suction surfaces arranged in a dense distribution state.

Action The anti-slip material should be pressed from the top of the mat body onto the top plate surface, since many fine air bubbles that are open on the surface of the soft synthetic resin foam layer that constitutes it function as suction cups. By sticking together, the whole surface is firmly adsorbed to the top plate surface, and even if the top plate is in an inclined posture or a vertical posture, the weight of the main body of the mat is supported to maintain the adsorption state and the desk mat slides. Demonstrates the function of reliably preventing falling.

Such a non-slip material is, for example, a soft synthetic resin emulsion containing a foaming agent, which is heated (typically 160
After being applied on a thin base made of a heat-resistant synthetic resin film that withstands about (° C.) (see FIG. 4 (A)), this is heated and foamed to form a foam layer [see FIG. 4 (B)]. By slicing the skin layer on the surface,
Can be easily manufactured. That is, since a large number of fine bubbles existing in the surface layer portion of the foam layer are laterally cut by the slice, the remaining spherical surface of each bubble is present on the new surface of the foam layer after slicing. A large number of minute suction cups composed of are formed (see FIG. 4 (C)). Then, this foam layer may be cut together with the base into a desired size and shape, and may be adhered and fixed to the back surface side of the flexible mat main body via the adhesive to form a non-slip material.

The above-mentioned non-slip material may be provided on the entire back surface of the mat body, but since it has a very strong adsorption action, it is taped in consideration of economy, for example, as a tape shape, on the four side edges or the long side of the mat body back surface. The shape and size of the mat body, such as sticking along one of the opposite side edges on the short side or sticking to the corner of the back surface of the mat body as a rectangle or triangle,
It may be provided at an appropriate position depending on the weight. If the mat body has sufficient heat resistance, it is possible to directly form a foam layer similar to the above with this body as a base.

The foam layer is preferably a closed-cell foam or a foam mainly containing closed cells and partially containing open cells in forming a minute sucker portion by the bubbles, and a completely open-cell foam such as a sponge. Is not suitable, and in particular, a soft synthetic resin foam having a foaming ratio of 2 to 10 and having bubbles distributed in a range of 0.01 to 1 mm is recommended. That is, if the expansion ratio is too small, the area ratio of the fine suction cups on the surface of the foam layer is reduced, and conversely if it is too large, the number of open cells is increased and the ratio of the bubble component functioning as a suction cup is decreased. However, neither of them can obtain a sufficient adsorption action. In addition, the adsorption action becomes insufficient when the distribution width of the bubble size is too wide or when the average size is too large or too small.

Embodiment Hereinafter, the invention will be described based on illustrated embodiments.

In FIGS. 1 to 3, (1) is a rectangular desk mat, and a tape-shaped non-slip material (3) is adhered to the back side of the flexible mat body (2) along the four side edges. It is attached via the agent (4).

Then, the mat body (2) is formed on a flexible base sheet (21), which is composed of a base material layer (21a) both made of synthetic resin and a coloring layer (21b) laminated on the base material layer (21a). The upper sheet (22) made of transparent synthetic resin with high elasticity is fused at both side edges (22a) (22a) on the long side of the upper sheet (22) and is opened between both sheets (21) (22). It is designed so that a piece of paper or the like can be inserted and inserted from the short side.

The non-slip material (3) comprises a thin base (3a) made of a polypropylene film and a foam layer (31) made of a polyurethane-polyacryl mixed soft synthetic resin provided on the base (3a). It is glued on the side to the back of the mat body (2). Then, the foam layer (3
On the surface of 1), as shown in FIG. 3, a large number of concave spherical spherical minute suction cups (33) formed of fine bubbles (32) opened on the surface are arranged in a dense distribution state. It constitutes the adsorption surface.

The non-slip material (3) is prepared by adding a foaming agent to a mixed emulsion of polyurethane and polyacrylic, applying this emulsion on the base (3a) as shown in FIG. 4 (A), and heating the coating layer (30). After foaming to form a soft foam layer (31) as shown in FIG. 4 (B), the skin layer (31) of the foam layer (31) is formed along the surface direction as shown by the broken line in the figure.
It is manufactured by slicing and removing a) and cutting it into a tape shape, and each fine air bubble (32) in the surface layer portion laterally cut by the slice as shown in FIG. 4 (C). The minute suction cup portion (33) is formed by the remaining portion of ().

For example, as shown in FIG. 5, the desk mat (1) having the above-described structure is placed on a tilting top plate (6) of a writing bureau type desk (5) and its peripheral portion is placed on the top plate (6). ) By pressing it against the surface, the non-slip material (3) is firmly adsorbed on the surface of the top plate (6), and the top plate (6) is no longer centered on the pivot pin (7) as shown by the phantom line in the figure. As a result, it does not slip down even when it is rotationally displaced to the standing posture when not in use, and thereafter, the sticking state is maintained even if the standing posture is long-term and the top plate (6) is repeatedly rotated. Therefore, after the desk mat (1) is once attached, the top plate (6) can be used with the mat (1) always laid in a fixed position without any special operation.

In addition, this desk mat (1) can be firmly attached to an inclined top plate such as a drafting table by using the suction action of the anti-slip material (3) as in the above, and can be fixed in a normal desk horizontal state. Even when it is laid on a top plate, it has an advantage that displacement is prevented by the suction action. On the other hand, since the desk mat (1) adsorbed on the top plate can be easily peeled off, it can be easily removed as needed, and the adsorbing power is reduced due to dust adhesion on the surface of the anti-slip material (3). In that case, the original strong adsorptive power is restored again by washing with water and washing away the deposits.

In the above embodiment, the mat body is composed of an upper sheet and a base sheet made of synthetic resin, which are fused at both side edges.
In the present invention, a single-layered sheet or a laminated sheet is used as the mat body, and a sheet having a fiber layer in the lamination can also be used.

Effect of the Invention According to the present invention, the suction action of the anti-slip material makes it possible to firmly attach it to the tilting top plate or the tilted top plate so that it does not slip off, and it can be easily removed from these top plates. Moreover, it is possible to provide a desk mat which is not sticky, does not stain the top plate surface, does not damage the top plate, and has no difference in suitability depending on the top plate material.

In particular, the foam layer of the non-slip material is made of a closed-cell foam having a foaming ratio of 2 to 10 times and a diameter of the cells distributed in the range of 0.01 to 1 mm, and the surface of the bubbles is Due to the fact that a large number of minute suction cups due to openings are formed as a suction surface in which they are arranged in a dense distribution state, the above-mentioned suction effect on the top surface is most effectively exhibited with the extremely thin anti-slip material. There is an advantage that the mat can be pressed and the mat is not obstructed in use such as the flatness of the mat being impaired by the attachment of the anti-slip material to the mat body.
