Description

The present invention relates to an adhesive mat that has high tackiness in necessary portions, moderately low tackiness in necessary portions, or no tackiness in unnecessary portions.

  With the spread of mobile phones in recent years, there is an increasing demand for technology for fixing mobile phones to predetermined locations. For example, mobile phone stores display a variety of mobile phones so that they can be easily viewed in the store, and are removable so that customers can pick up a mobile phone of their favorite model. A display method is required.

  Therefore, in Patent Document 1, a simple display stand is formed by providing a crease in plastic, hard paper, etc., assembling a front plate, a bottom plate, and a rear plate into a triangle, and fixing an adhesive mat coated with an adhesive on the front plate. The idea is disclosed. As a result, the mobile phone can be detachably fixed by pressing the mobile phone against the surface of the adhesive mat having adhesive force, so that it becomes a display stand, using low-cost raw materials, easy to assemble, It can be used as an interior by placing it on a table, and it can also be used for advertising, decoration and other purposes from its simple appearance.

Such an article fixing method using the adhesive strength of the adhesive mat is also utilized in other fields. For example, in Patent Document 2, as a joining device for preventing overturning when equipment such as a vending machine is installed, an adjuster part that fixes legs of the equipment and an adjuster part are fixed to the floor surface. The invention of the joining device of a leg part, such as equipment, and a floor surface which has a double-sided adhesive mat for the purpose is disclosed. This eliminates the need for drilling holes on the floor as compared to conventional anchoring methods using fixing brackets, so there is no need for extra expenses or time, and when removing equipment. It is said that it is not necessary to close the hole made in the floor.

  However, in the invention of the simple display stand described in Patent Document 1, it is assumed that a soft plastic containing an appropriate amount of an anti-slip liquid and an adhesive is used as the adhesive mat, but such an adhesive mat has a strong adhesive force. Generally, it adheres to a mobile phone having a smooth back surface and cannot be removed smoothly. In extreme cases, the adhesive mat may even be peeled off from the front plate together with the mobile phone.

  Furthermore, when using as a mobile phone holder for users, even when trying to use a mobile phone or when a phone call is made, it will not be removed smoothly and will be inconvenient, and it will be powerful. There is a problem that dust and the like easily adhere to the back surface of the mobile phone due to the adhesive, and the mobile phone becomes dirty.

  In addition, when the technique described in Patent Document 2 is applied to fixing home appliances such as a liquid crystal television, the double-sided adhesive mat is too strong, so that the double-sided adhesive mat is attached to the back of the leg portion of the liquid crystal television. When the LCD TV is placed on the TV stand, it is excellent in stability, but if you try to move the LCD TV as much as possible, the double-sided adhesive mat that adheres to the top of the TV stand will In some cases, the wood layer on the surface peels off, and in the case of a TV stand that has been painted, the coating is peeled off.

Therefore, in the present invention, a mobile phone, a liquid crystal television or the like can be securely fixed to an arbitrary place, and can be easily removed and moved, and can be easily manufactured at a very low cost . It is an object to provide a mat .

The pressure-sensitive adhesive mat according to the invention of claim 1 is a pressure- sensitive adhesive mat made of a synthetic resin having pressure-sensitive adhesiveness and elasticity and manufactured by injection molding, and has substantially the same height over the entire surface. A plurality of convex portions are provided.

  Here, as the “synthetic resin having adhesiveness and elasticity”, styrene thermoplastic elastomer, urethane thermoplastic elastomer, and the like can be used. As the shape of the “plurality of convex portions”, various shapes such as a cylindrical shape, a hemispherical shape, a triangular prism shape, a quadrangular prism shape, and a truncated cone shape can be adopted. Further, the “plurality of convex portions” may have different shapes and sizes as long as the heights are substantially the same.

Moreover, the back surface side of the said adhesive mat | matte consists of a synthetic resin which is smooth and the said back surface side also has adhesiveness. In this case, when a synthetic resin having the same adhesiveness and elasticity is used on the front side and the back side, it can be injection-molded integrally.

The plurality of protrusions occupy 30% to 80% of the total area on the front surface side, and the plurality of protrusions cut a substantially hemispherical shape or a substantially hemispherical top portion flatly. It has a substantially trapezoidal shape. Furthermore, the outer diameter of the plurality of protrusions is obtained by the range of 2 mm to 10 mm.

The pressure-sensitive adhesive mat according to the first aspect of the present invention is a pressure-sensitive adhesive mat that is made of a synthetic resin having adhesiveness and elasticity on the surface side and is manufactured by injection molding, and has substantially the same height over the entire surface side. A plurality of convex portions are provided.

  Here, as the “synthetic resin having adhesiveness and elasticity”, styrene thermoplastic elastomer, urethane thermoplastic elastomer, and the like can be used. As the shape of the “plurality of convex portions”, various shapes such as a cylindrical shape, a hemispherical shape, a triangular prism shape, a quadrangular prism shape, and a truncated cone shape can be adopted. Further, the “plurality of convex portions” may have different shapes and sizes as long as the heights are substantially the same.

  With such a configuration, the back surface of the adhesive mat is fixed to an arbitrary place with a double-sided tape or an adhesive, and the mobile phone is placed on the surface, so that the back surface of the mobile phone is made of a synthetic resin having adhesiveness and elasticity. That is, it sticks over a plurality of convex portions having almost the same height, and does not come off to the extent that a little force is applied. Therefore, for example, by installing the adhesive mat of the present invention in an automobile, it can be fixed without being displaced at all by shaking or shock while the automobile is running.

  And since the adhesive force on the surface of the adhesive mat is moderately reduced due to the provision of the plurality of convex portions, the mobile phone can be easily removed from the surface of the adhesive mat when necessary, and Can be removed smoothly. And there is no fear that the back of the mobile phone gets dirty. Furthermore, since it is manufactured by injection molding, it can be mass-produced at a very low cost.

  In addition, by fixing the back surface of the adhesive mat to the back surface of the leg portion of a liquid crystal television or the like and placing it on a TV stand or the like with the surface provided with a plurality of convex portions down, Even if the liquid crystal TV is moved, the TV stand can be reliably prevented from falling over due to the appropriate adhesive force on the surface and the surface of the adhesive mat does not adhere to the upper surface of the TV stand more than necessary. It is possible to move smoothly without damaging the upper surface.

 In this way, an adhesive mat that can securely fix a mobile phone, a liquid crystal television, etc. in an arbitrary place, can be easily removed and moved, and can be easily manufactured at a very low cost. Become.

Moreover, the back surface side of the adhesive mat is made of a synthetic resin that is smooth and the back surface side is also adhesive. In this case, when a synthetic resin having the same adhesiveness and elasticity is used on the front side and the back side, it can be injection-molded integrally.

  Thereby, the adhesive mat can be installed in an arbitrary place by sticking the back surface side of the adhesive mat with adhesive force. For example, when installing in a car, the back side of the adhesive mat may be pressed and attached to the surface of a dashboard or the like, and when used indoors, it may be attached to a flat surface such as a desk. In a mobile phone store, a display stand can be obtained simply by sticking to a triangular base made of plastic or the like.

  Furthermore, when used for preventing a liquid crystal television or the like from falling, the back surface side of the adhesive mat may be attached to the back surface of a leg portion of the liquid crystal television or the like. If the adhesive strength on the front side decreases due to dust or the like after repeated use, the back side of the adhesive mat is peeled off and removed, washed with water and dried to restore the original adhesive strength. Can be restored and used again.

  In this way, an adhesive mat that can securely fix a mobile phone, a liquid crystal television, etc. in an arbitrary place, can be easily removed and moved, and can be easily manufactured at a very low cost. Become.

  As an application of the adhesive mat according to the present invention, for example, there is a mouse pad for a personal computer. In other words, by using a synthetic resin that does not have adhesiveness on the back side and has excellent slipperiness, if it is placed on a desk with the back side facing up, even if you move the mouse, The sticky mat is not displaced, and the upper surface is smoothly formed of a synthetic resin having excellent slipperiness, so that the mouse can be moved very smoothly and a high-quality mouse pad is obtained.

  In this manner, the adhesive mat can be reliably fixed at an arbitrary place, can be easily removed and moved, and can be easily manufactured at a very low cost.

Further, the plurality of convex portions occupy 30% to 80% of the total area on the surface side, more preferably 50% to 70% of the total area.
As a result of intensive experiment research, the present inventor has found that when the area of the plurality of convex portions occupies 30% to 80% of the total area on the surface side, it becomes a better adhesive mat. The present invention has been completed based on the findings.

  That is, if the area of the plurality of convex portions is less than 30% of the total area on the surface side, the adhesive strength on the surface side is too low, and when used for a mobile phone holder or the like, the inclination of the installation place is steep If the area of the plurality of protrusions exceeds 80% of the total area on the surface side, the adhesive force on the surface side is too large, and it may become a holder of a mobile phone. If used, removal may not be performed smoothly. Therefore, the area of the plurality of convex portions is preferably in the range of 30% to 80% of the total area on the surface side.

  Furthermore, when the area of the plurality of convex portions is within the range of 50% to 70% of the total area on the front surface side, when used for a mobile phone holder or the like, it vibrates even when the installation place is steeply inclined. This is more preferable because there is no risk of shifting with the like, and the removal can be surely performed smoothly.

  In this way, an adhesive mat that can securely fix a mobile phone, a liquid crystal television, etc. in an arbitrary place, can be easily removed and moved, and can be easily manufactured at a very low cost. Become.

Furthermore, the plurality of convex portions have a substantially hemispherical shape or a substantially trapezoidal shape in which a top portion of the substantially hemispherical shape is cut flat.
When the plurality of convex portions are formed in a substantially hemispherical shape, the surface to be adhered to the surface side of the adhesive mat (the back surface of the mobile phone, the top surface of the television stand on which the leg portion of the liquid crystal television or the like is placed, etc.) Since the contact area becomes smaller, it is easier to remove and move. On the other hand, if the convex parts are made into a substantially trapezoidal shape with the top of a substantially hemispherical shape cut flat, the contact area becomes larger and the contact area becomes larger. Strength increases.

  Therefore, depending on the application of the adhesive mat and the adhesive strength of the synthetic resin used on the surface side of the adhesive mat, the surface of the adhesive mat is made by making the plurality of convex portions into a substantially hemispherical shape or a substantially trapezoidal shape. The adhesiveness of the side can be adjusted more appropriately. And by making the convex part into a substantially hemispherical shape or a substantially trapezoidal shape with the top part of the substantially hemispherical shape cut flat, it becomes easy to produce a mold for injection molding, and the mold releasability at the time of injection molding is improved. Therefore, manufacture becomes easier.

 In this way, an adhesive mat that can securely fix a mobile phone, a liquid crystal television, etc. in an arbitrary place, can be easily removed and moved, and can be easily manufactured at a very low cost. Become.

In addition, the outer diameter of the plurality of convex portions is in the range of 2 mm to 10 mm, more preferably in the range of 3 mm to 7 mm.
As a result of repeated earnest experimental researches, the present inventors have found that when the plurality of convex portions have a substantially hemispherical shape or a substantially trapezoidal shape obtained by flatly cutting the top of the substantially hemispherical shape, It has been found that when the thickness is in the range of 2 mm to 10 mm, the adhesive mat is more excellent, and the present invention has been completed based on this finding.

  That is, if the outer diameter of the plurality of protrusions is less than 2 mm, the contact area becomes too large when the plurality of protrusions are densely provided on the surface side, and smooth removal and movement are difficult. If the outer diameter of the plurality of protrusions is less than 2 mm in the protrusions having an outer diameter of about 5 mm or more, the heights are almost the same. This may make it difficult to become a useless part that is not involved in fixing.

  On the other hand, if the outer diameter of the plurality of protrusions exceeds 10 mm, it becomes difficult to densely provide the plurality of protrusions on the surface side, so that the contact area is reduced, and the necessary appropriate adhesive force is obtained. It may not be obtained. Therefore, it is preferable that the outer diameter of a some convex part exists in the range of 2 mm-10 mm.

  Furthermore, when the outer diameter of the plurality of convex portions is in the range of 3 mm to 7 mm, there is no possibility that the contact area becomes too large or too small, and an appropriate adhesive force can be ensured. . Then, between the plurality of convex portions having an outer diameter of 6 mm to 7 mm, a plurality of convex portions having an outer diameter of 3 mm to 4 mm or 4 mm to 5 mm can be mixed. This is more preferable because the portion can be provided densely on the surface side and an appropriate adhesive force can be obtained more reliably.

  In this way, by securing an appropriate adhesive force on the surface side, it is possible to securely fix a mobile phone, a liquid crystal television or the like to an arbitrary place, and it can be easily removed and moved, and is extremely inexpensive. And it becomes an adhesive mat which can be manufactured easily.

The diameter of the adhesive mat 11A is 4 cm, and the thickness is 4 mm from the top of the convex portion 13A to the back surface 15A.

  The adhesive mat 11 according to the second embodiment and the adhesive mat 11A according to the modified example of the second embodiment are provided with a cushioning material and an anti-tip material when the liquid crystal television is placed on a TV stand. Will be described with reference to FIG.

 As shown in FIG. 7 (a), a display device such as a liquid crystal television 16 is often placed on a television stand 18 or the like so as to be set at a height that is easy for the user to see and does not get tired. is there. At this time, the adhesive mat 11 according to the second embodiment is attached to the back side of the metal legs 17 of the liquid crystal television 16 and used as a buffer material and a fall prevention material.

  More specifically, as shown in FIG. 7B, the back surface 15 of the adhesive mat 11 according to the second embodiment is attached to the back side of the leg portion 17 so that the convex portion 13 of the front surface 12 is formed. The liquid crystal television 16 is placed on the television stand 18 so as to be in contact with the surface of the television stand 18. Thereby, it is possible to prevent the surface of the TV stand 18 from being damaged by the back side of the metal legs 17 being in direct contact with the surface of the TV stand 18.

  Here, as shown in FIG. 7A, the convex portions 13 of the surface 12 of the adhesive mat 11 attached to the five portions of the leg portion 17 are formed on the surface of the television stand 18 by the weight of the liquid crystal television 16. Pressed. However, the front surface 12 of the adhesive mat 11 is provided with a plurality of convex portions 13, so that the adhesive force is lower than that of the back surface 15 having a smooth surface, and the liquid crystal television 16 is shaken by an earthquake or the like. It has moderate adhesiveness that can prevent the television 16 from falling.

  And since it does not have strong adhesiveness like the back surface 15 which has a smooth surface, when placing the liquid crystal television 16 on the television stand 18 for a long time and trying to move the liquid crystal television 16 In addition, the surface 12 of the adhesive mat 11 having appropriate adhesiveness is smoothly separated from the surface of the TV stand 18.
