Description

  The present invention relates to a pressing sucker. (Suction cup and suction cup are synonymous).

For suction cups, there are pressing suction cups, tension suction cups, and suction (deaeration) suction cups. For pressing suction cups, a bowl-shaped object is pressed against the surface to be sucked, and the force to return by the elasticity of the suction cups works. In this state, a negative pressure state is created, and it is fixed as if it is sucked by the pressure difference between the negative pressure portion and the atmospheric pressure. As the adhesive sheet, a resin-based elastomer has been proposed for each company.
JP2007-285494. JP2007-040510. JP2007-205562A.

  An ordinary pressing sucker has a uniform material made of a soft resin, which is composed of a bowl-shaped portion and an attaching portion provided on the outside by integral molding. The material was selected to improve familiarity with the contacted surface. Even so, it was proposed that a resin-based elastomer or the like should be provided with a familiar material between the suction surface and the suction cup to improve the familiarity. However, the structure was complicated. Resin-based elastomers have been proposed for each company as adhesive sheets, and they were sold as tacking materials and earthquake-resistant mats. Although it exerts a drag, many of them have a performance of slipping (slipping) or peeling in a long time. * As a definition of the term, the resin-based elastomer is defined in the present invention as a condition that the resin is in a gel state and has a sticky surface, and the actual materials include elastomers such as silicon, polyurethane, and urethane. In the present invention, a gel-like state is defined as a pudding, konjac or cocoon.

  In order to solve the above problems, the familiarity is improved by making the material of the sucker with resin-based elastomer. The shape is a ring as shown in FIG. 1, and when the plate is pressed, the air in the ring is pushed out. It is adsorbed so as to be attracted by the pressure difference from the external atmospheric pressure. From the point of view of the pressure sensitive adhesive sheet, a cavity is applied to the vicinity of the center of the sheet member, and a plate is applied to the plate to press and crush it. This creates a synergistic effect of adhesive performance and pressing function.

  Making the sucker material with resin-based elastomer improves familiarity and reduces air leakage. The shape of the surface to be attracted can be adapted to a certain degree of unevenness, for example, it can be maintained even on a frosted glass surface or a matte surface. The maintenance time is increased due to a synergistic effect of the adhesiveness of the material body and the pressing pressure (adsorption force) of the suction function. Since it is a simple shape, there is also an advantage in production. Although there is a perforated double-sided suction cup in comparison with what has been proposed in the past, there is an advantage in the present invention in the simplicity of the structure. Since the structure is simple, it can meet a wide variety of demands. For example, it is possible to select materials that are slightly harder and softer by selecting materials, and can be selected by the size of the outer diameter. It is possible to select the size. The range of use is widened because there are various mounting members on the outside. Since the suction cup is ring-shaped, a small shape ensures a large force and sustainability. The reason for this will be explained with reference to FIG. Since the thickness direction and space area direction are changing, the negative pressure can be greatly changed by comparing with the bowl shape, and the durability until this place returns will be increased. .

  In comparison with the adhesive sheet, if a negative pressure state is created by creating a cavity near the center of the sheet member and pressing and crushing it against the plate to remove the air in the cavity, the mechanism is always pressed by atmospheric pressure. Therefore, it is possible to reduce the size of the product, to increase the attractiveness, and to extend the duration, which is naturally a synergistic effect of both properties. As a seismic aid, it can be used as a base for TV monitors as shown in Fig. 6, and since gravity from above is applied during normal times, there is little air leakage and the suction cup has the fixing ability during earthquakes. Is also useful. That is, it can exhibit a larger fixing ability than a simple adhesive ability. It goes without saying that even if it is shaped like a box, it can be used to prevent falling and skidding if it is installed on the bottom. There is an effect that either the concept from the suction cup can be regarded as an adhesive sheet, or the suction sheet function is provided from the field of the adhesive sheet, which is an intermediate point and both performances are effectively used.

  Although what is attached to the suction cup is a plate-like thing, it is also a great effect that the variation of what is attached to the outside becomes wide. In the case of a hard plate, it can be used by using a venting technique. A plurality of suction cups and a single plate can be used, and the suction cups can be arranged according to the stress distribution. As a representative example, an arrangement as shown in FIG. 5 can be performed. Although the shower head is written in FIG. 5, it becomes possible to cope with a shape like a bracket. It is also noted that although the size and weight are limited, the surface of the box can be directly attached to the attracted surface. In addition, as shown in FIG.

  In the case where the mounting plate is a flexible material, the plate is bent by pressing the central portion of the suction cup, and the air is released, so that the mounting plate is directly attached to the suction surface. As shown in FIG. 7 (r), it is effective to attach a film to the glass surface. Naturally, the film can be processed to make a bag-like object, which can be attached to the surface to be adsorbed, and can be widely used as shown in FIGS.

BEST MODE FOR CARRYING OUT THE INVENTION 1

  The present invention will be described with reference to the drawings. Claim 1 is a ring-shaped suction cup (1), wherein the cross-sectional shape of the ring is rectangular, the material is a resin elastomer, and the outer shape of the ring is about 5 mm to 50 mm. The inner diameter is about 80% to 30% of the outer shape, and the thickness is about 2 mm to 8 mm. In FIG. 1, it represented with the top view (a) and perspective view (b) of the main body of this invention.

Form 2 for carrying out the invention

  In Claim 2, since it is a ring-shaped suction cup, the internal air does not easily escape when pressed. Especially, if the attachment is rigid (not bent), it will be like an air spring and cannot be adsorbed. . However, as a tool for extracting air, a wire that bends in an L shape and a portion that bends in a corrugated shape is formed on one side, the length is about 60 mm, the folded grip portion is about 25 mm on the other end, and the thickness of the wire is 0. Remove air with a 5Φ ~ 1.0Φ. For usage, install the ring from the inside to the outside and pull it out under pressure. At this time, hold the handle and rotate it up and down, move left and right, and pull it out.

Form 3 for carrying out the invention

  In claim 3, a handle (20) is provided at one end of a stranded wire (21) in which at least three fine wires are twisted to form a single wire, and the thickness of the stranded wire is 0.5Φ-1. The length is about 0Φ and the length is about 100 mm. It is the idea to use it instead of pipes because it will surely create a space when it is combined with 3 or more when extracting air. Compared to pulling out while moving in the previous paragraph and the previous paragraph, there is a feature in that air begins to escape when pressed. The configuration is expressed in FIG.

Form 4 for carrying out the invention

  In claim 4, by using the double-sided suction cup according to claim 1, a wire is installed on the contact surface of the suction cup so as to extend from the inside to the outside of the ring, and the suction cup is pulled out with the pressure applied to the inside of the ring. This is a method of removing air from a double-sided suction cup. Here, the wire is the most suitable when the wire method described in the previous paragraph is repeated many times, and the wire is also a form of the wire. However, the same applies to yarns and wires if they are not repeated. As a special case, when there is no space for drawing, it may be more convenient to place the yarn and pull it out. The case where there is no space for pulling out is the case where the side wall of the box interferes with the case where a plate is to be attached to the entire bottom surface of the box, and the overall explanation is that the attachment to the recess Is the case. Since there are both when actually used, it is convenient to put both of them together with the handle portion, so it is described in claim 7 (illustration is omitted). Since things are small, they can be prevented from being lost. It is also useful to color wires and stranded wires to prevent loss. It is even better if it is a fluorescent color.

Form 5 for carrying out the invention

  According to a fifth aspect of the present invention, the double-sided suction cup according to the first aspect and a flexible address plate (4) are formed, and the address plate is folded into a bag shape. In the case where the contact plate is thin and flexible, if the center part is pressed directly, the suction cup is deformed in an elliptical shape, and further protrudes from the tip part to escape the air. The basic principle is as shown in FIG. As shown in FIG. 9 (r), the air comes out in an ellipse, and the place where the air comes out pops out and sticks. In this case, the width of the ring should be relatively large, and approximately 1/4 or more of the outer diameter is recommended. This is because when the width is small, the ellipse is further flattened by the atmospheric pressure and exceeds the restoring force. Under this condition, the board is folded and used in a bag shape with a margin. The film is processed outside the suction cup to create a mounting part for wide use. An example is shown in FIG. When a film-like object is attached to the window, the principle is as shown in FIG. 8, but the sucker is used in the product of FIG. Described here on the category of mounting plates.

Form 6 for carrying out the invention

  According to the sixth aspect of the present invention, there is an advantage that the outer shapes are the same, and there are advantages that the suction cups are provided in multiple layers to adjust the thickness and that the amount of air to be pushed out is increased by changing the inner diameter of the ring. As shown in FIG. 8, the larger the contact area at the contact portion, the smaller the amount of air leakage, and the larger the internal space capacity is useful. Naturally, it is possible to create a bulging shape in the space, but it is convenient to process in multiple layers as an efficiency. In this case, making products corresponding to the thickness increases the types to make, so the effect of reducing the number of parts There is.
