Adsorption port is fixed to the wall by using a vacuum force has the advantage that it is easy to attach and detach, leaving no marks even after being removed, and because of this advantage is widely used as a means for hanging shelves or household goods. However, such an adsorption port has a disadvantage that it is difficult to attach to the surface is not smooth. For example, a tile is attached to a kitchen wall or a bathing wall, and a lot of tiles have a protruding pattern formed on the surface or irregularities formed on the surface in order to increase decorativeness. However, it is difficult to attach an adsorption port to the pile with such a smooth surface.
For this problem, an adsorption port that can be attached to a wall surface having a smooth surface has been proposed. As shown in FIG. 1, a conventional suction hole includes a cap-shaped case 3 having a through hole 2 formed at a center thereof, and a screw 4 fitted into the through hole 3 to be coupled to the case 3. The suction plate 5 provided on the lower side, the auxiliary ring 6 which is provided on the bottom circumference of the case 3 and overlaps with an upper surface of the end of the suction plate 5, and the upper end of the screw 4 Composed of the adjusting mechanism (7), the auxiliary ring (6) is made of a polyurethane of high viscosity gel type. When the suction port is pressurized to the adhered surface 1, the auxiliary ring 6 is in close contact with the adhered surface 1 to seal the inside of the suction plate 5 so that the adsorption portion is attached to the adhered surface 1, and the auxiliary ring 6 ) Also contributes to the adhesion of the suction port.
On the other hand, since the auxiliary ring 6 is made of a gel type polyurethane having a high viscosity, when the adsorption port is pressed on the adhered surface 1 whose surface is not smooth, the auxiliary ring 6 is deformed by an external force. At this time, the auxiliary ring (6) is deformed according to the bending shape of the adherend surface with a large deformation in the lateral direction, the external force is almost exhausted to the deformation of the auxiliary ring (6) the external force is the auxiliary ring (6) It cannot be delivered to the end of the adsorption plate 5 through. Therefore, as shown in FIG. 2, when the adsorption port is pressed on the surface 1 to which the surface is not smooth, the auxiliary ring 6 is deformed by an external force and adheres to the surface 1 to be adhered to, but the end of the adsorption plate 5 is closed. Is not deformed to conform to the surface curvature of the adhered surface 1, and the end of the suction plate 5 is not in close contact with the adhered surface 1. However, since the auxiliary ring 6 is pressed to the adherend surface 1 and the inside of the adsorption plate 5 is sealed, a vacuum is generated inside the adsorption plate 5 so that the adsorption port is attached to the deposition surface.
On the other hand, since the gel-type polyurethane forming the auxiliary ring 6 has air permeability, the air is vented into the auxiliary ring 6 over time. As described above, the end of the adsorption plate 5 is deposited. Since it is not in close contact with the surface (1), when the aeration is made into the auxiliary ring (6), the aeration is also made into the adsorption plate (5) and the vacuum inside the adsorption plate (5) is broken. Therefore, the state in which the adsorption port is attached to the adhered surface 1 cannot be maintained and falls. As a result, the conventional adsorption port does not last long on the adhered surface where the surface is not smooth.
In addition, in the conventional adsorption port, as described above, when the external force is applied, although the auxiliary ring 6 is deformed according to the surface curvature of the adhered surface, the auxiliary ring 6 is deformed largely in the lateral direction while being pressed. The deformation in the vertical direction is minimal. Therefore, when the recessed portion (a) having a relatively deep depth is formed on the adhered surface (1), since the auxiliary ring (6) does not fill the recessed portion (a) of the adhered surface (1) and the adhered surface (1) The adhesiveness of is inferior. Therefore, the conventional adsorption port has a disadvantage in that it is still difficult to attach to the adhered surface 1 having the relatively deep concave portion a.
In addition, the auxiliary ring 6 adheres to the adherend surface 1 because of its high viscosity. Therefore, if the adsorption port is attached to and detached from the adherend surface, the auxiliary ring 6 does not easily fall off the adhered surface 1, Remains.
The present invention is to solve the above problems, the object of the present invention is not only firmly attached to the surface of the surface is not smooth, but also firmly attached to the adhered surface is maintained continuously, usability is not left It is to provide a good new structure of the adsorber.
According to the present invention, a case of a cap-shaped case 10 formed with a hard synthetic resin and having a through hole 12 formed in the center and a screw shaft 22 aligned with the through hole 12 is coupled to the case ( 10) the adsorption plate 20 made of a soft material provided on the lower side, the fastener 30 screwed to the tip of the screw shaft 22, and a portion of the bottom surface so as to overlap the upper surface of the circumference of the adsorption plate 20; And a pressing ring 40 fitted to a circumference of the bottom of the case 10, wherein the pressing ring 40 is provided with a soft material having a lower hardness than the suction plate 20. .
According to another feature of the invention, the end of the case 10 is formed with a downward bent end portion 18 which is located outward than the outer peripheral surface of the pressing ring 40, the bottom surface of the case 10 or the suction plate ( The lower side wall 16 or the upper side wall 24, which is located inwardly than the inner circumferential surface of the pressing ring 40, protrudes from the upper surface of the pressing ring 40, and when the pressing ring 40 is pressed against the adhered surface 1, A suction port is provided, characterized in that deformation of the pressing ring 40 in the lateral direction is regulated by the downwardly bent end 18 and the downward side wall 16 or the upward side wall 24.
According to another feature of the present invention, an end of the suction plate 20 is provided with an adsorption port, characterized in that the wing 26 is formed extending laterally.
According to another feature of the invention, the pressure ring 40 has a hardness of 7 ~ 20 (Shore A), the suction plate is provided with an adsorption port, characterized in that the hardness of 50 ~ 80 (Shore A).
According to the present invention having the above configuration, when an external force is applied to the pressure ring 40, the pressure ring 40 is deformed to fill the recessed portion a formed in the adhered surface 1, and to be in close contact with the adhered surface 1. In addition, the pressure ring 40 induces deformation of the end of the adsorption plate 20 so that the end of the adsorption plate 20 is also deformed in accordance with the bending of the adhered surface to be in close contact with the adhered surface 1. Therefore, the adsorption port is effectively attached to the surface 1 to which the surface is not smooth, and in particular, even though the air is slowly vented into the pressure ring 40 during use due to the breathability of the material forming the pressure ring 40. As described above, since the end of the adsorption plate 20 is in close contact with the adhered surface 1, the airtightness inside the adsorption plate 20 is maintained, so that the adsorption force of the adsorption port is continuously maintained.
Moreover, since the deformation of the pressing ring 40 in the lateral direction is restricted by the downward bending end portion 18, the downward side wall 16 and the upward side wall 18, the possibility of deformation of the pressing ring 40 in the vertical direction. Since the pressing ring 40 is deformed to fill the recessed portion a of the adherend surface even when a deep recessed portion a is formed in the adherend surface 1, the pressing ring 40 is deposited. It adheres to the surface 1. In addition, when the wing 26 having a relatively thin thickness is provided at the end of the suction plate 20, and the wing 26 is configured to be pressed by the pressure ring 40, the wing 26 is more sensitive. Since the deformation is caused by the bending of the adherend, the adhesion between the suction plate 20 and the adherend 1 is improved.
In particular, preferably when the hardness of the pressure ring 40 is adjusted to 7 ~ 20 (Shore A), the hardness of the adsorption plate 20 is 50 ~ 80 (Shore A), the self-deformation of the pressure ring 40 is also smoothly In addition, the end of the adsorption plate 20 may be pressed to induce deformation of the adsorption plate 20, and the women or the elderly who are relatively weak in force may also attach the adsorption port to the adhered surface without difficulty.
Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. 3 is a cross-sectional view showing an embodiment of the present invention, Figures 4 and 5 are a cross-sectional view and a perspective view showing the use state.
As shown in the present invention, a cap-shaped case 10 formed of a hard synthetic resin and having a through hole 12 formed at the center thereof, and a screw shaft 22 aligned with the through hole 12 are coupled to the case. (10) the adsorption plate 20 made of a soft material provided on the lower side, the adjusting device 30 screwed to the tip of the screw shaft 22, and a portion of the bottom surface made of the soft material is the circumference of the adsorption plate 20. It consists of a pressing ring 40 which is fitted to the peripheral portion of the bottom surface of the case 10 so as to overlap the upper portion.
The case 10 is formed of a hard synthetic resin, the center portion is formed to be convex upwards, and a concave hollow portion is formed inside the bottom surface to have a cap shape. In the center of the case 10 is formed a through hole 12 penetrated up and down, the outer end is formed with a downward bent end 18 is bent downward, the bottom of the case 10 is the downward bent end ( 18, the downward side wall 16 is formed at a position spaced apart by the thickness of the pressure ring 40. In addition, a fitting protrusion 14 fitted to an upper surface of the pressing ring 40 is formed at a bottom surface of the case 10 between the downward bent end 18 and the downward side wall 16. Preferably, the downward bending end portion 18 and the downward side wall 16 are adjusted so as not to protrude from the bottom surface of the pressing ring 40 in a state in which the pressing ring 40 is fitted. This is to prevent the bottom surface of the case 10 from contacting the deposition surface 1 when the suction port is pressed against the deposition surface 1.
The adsorption plate 20 has a disk shape, the screw shaft 22 is coupled to the center of the upper surface. The suction plate 20 is insert-injected with soft synthetic resin, rubber or the like so that the lower end of the screw shaft 22 is embedded. At the end of the suction plate 20, wings 26 extending laterally are formed. The wing 16 has a relatively thin thickness compared to other parts, preferably has a thickness of about 0.3 ~ 0.5mm. The suction plate 20 including the vanes 26 has a diameter smaller than the diameter of the case 10. The suction plate 20 is located inside the case 10 such that the screw shaft 22 is aligned with the through hole 12 of the case 10, and the adjusting hole 30 is disposed at the upper end of the screw shaft 22. When the fastening plate 20 is connected to the case 10. The adjusting device 30 is also formed of a hard synthetic resin, the outer peripheral surface of the finger groove 32 is formed so that the user can easily hold and manipulate by hand.
On the other hand, the pressure ring 40 has an outer diameter larger than the diameter of the suction plate 20 and smaller than the diameter of the case 10, the inner diameter is formed smaller than the diameter of the suction plate 20, the upper surface of the case An insertion groove 46 into which the fitting protrusion 14 of 10 is inserted is formed. Therefore, when the fitting ring 14 of the case 10 is inserted into the case 10 so that the pressing ring 40 is inserted into the insertion groove 46 of the pressing ring 40, the pressing ring 40 is the case of the case 10. Located between the downward bent end 18 and the downward side wall 16, a portion of the bottom surface of the pressure ring 40 overlaps the upper surface of the wing 26 of the suction plate 20, a portion of the bottom surface is exposed outward.
The pressure ring 40 is made of a soft material such as silicon or rubber, and is made of a material having a lower hardness than the adsorption plate 20. The pressure ring 40 preferably has a low hardness so that it is easily deformed by an external force when an external force is applied, but it must be able to induce deformation of the end of the adsorption plate 20 by transferring the external force to the end of the adsorption plate 20. The hardness of the pressure ring 40 needs to be adjusted. In the present invention, the hardness of the pressure ring 40 is limited to 7 ~ 20 (Shore A). In the case where the hardness of the pressure ring 40 is less than 7, when the external force is applied, the pressure ring 40 is effectively deformed according to the surface curvature of the adhered surface 1, so that the adhesion to the adhered surface 1 is increased. The transfer force transmitted to the adsorption plate 20 is reduced, so that the deformation of the adsorption plate 20 cannot be induced. When the hardness of the pressure ring 40 exceeds 20, the transmission force for transmitting the external force to the suction plate 20 is improved, but the deformation degree of the pressure ring 40 due to the external force is low, so that the surface of the adherend surface 1 is reduced. There is a disadvantage that the deformation is not sensitive to bending. Preferably, when the hardness of the pressure ring 40 is 7 ~ 20 (Shore A), the adsorption plate 20 is preferably a hardness of 50 ~ 80 (Shore A). When the hardness of the pressure ring 40 and the adsorption plate 20 is at this level, the female or the elderly can also attach the adsorption port to the adherend surface 1 without exerting a great force.
When providing the adsorption port which has such a structure, the case 10 is pressurized to the to-be-adhered surface 1 in the state which released the said adjustment port 40. FIG. When the case 10 is pressed against the adhered surface 1, the pressing ring 40 is deformed by an external force. When the adhered surface 1 is uneven and a recessed portion a is formed, the recessed portion a is different from the other side. Since the repulsive force against external force is smaller than that of the portion, the pressure ring 40 is driven into the recessed portion a to fill the recessed portion a. Moreover, the downward bending end portion 18 and the downward side wall 16 are restricted from deformation in the lateral direction of the pressure ring 40, so that the pressure ring 40 is prevented from spreading flat only in the lateral direction as in the prior art. Even when the depth of the portion a is deep, the pressing ring 40 effectively fills the recessed portion a, and the pressing ring 40 is in close contact with the adherend surface 1. And as the pressure ring 40 fills the recess (a), the external force of the same level as the other parts also acts on the recess (a) by the pressure ring 40, accordingly the pressure ring 40 The end of the suction plate 20, that is, the wing 26, which is superimposed on it, is also deformed according to the shape of the adherend surface 1. Since the wing 26 has a considerably thin thickness, the wing 26 is also sensitively deformed according to the curvature of the adhered surface 1 to be in close contact with the adhered surface 1.
In this manner, after pressing the suction port on the surface to be attached to the adjusting device (30). When tightening the adjusting device 30, as shown in Figure 4, the center portion of the suction plate 20 is lifted upward, as described above, the pressure ring 40 and the wing 26 of the suction plate 20 is the adhered surface Deformed according to the shape of (1) and in close contact with the adhered surface 1, when the center portion of the suction plate 20 is lifted, a sealed space having a vacuum pressure is formed between the adhered surface 1 and the suction plate 20. The suction port is attached to the adherend 1 by the vacuum pressure.
Figure 6 shows another embodiment of the present invention, the upper side wall 24 is formed on the upper surface of the suction plate 20, by the downward bending end 18 and the upper side wall 24 by the pressing ring (40) The lateral deformation of) is shown to be regulated. Preferably, the upward side wall 24 is located on the tip top surface of the wing 26. In some cases, the downward side wall 16 is formed on the bottom of the case 10, and the upward side wall 24 is formed on the upper surface of the suction plate 20 so that the upward side wall 24 is the downward side wall ( 16) may be configured to be inserted at the end.
In the present invention having the above configuration, since the pressure ring 40 has an appropriate level of hardness, when an external force is applied, the concave portion (a) of the adherend surface 1 is filled and adhered to the adherend surface. Since the recessed portion (a) of the surface (1) is filled by the pressure ring (40) so that the same level of external force is applied to the recessed portion (a), the blade (26) of the suction plate (20) is also attached to the adhered surface (1). It is deformed according to the curvature of the and close to the adherend surface (1). In addition, even though the air is gradually vented into the pressure ring 4 due to the air permeability of the material forming the pressure ring 40, the wing 26 of the suction plate 20 is deformed according to the bending of the adherend surface 1. And the state of being in close contact with the adhered surface 1, the airtightness into the suction plate 20 is maintained. Therefore, the adsorption port according to the present invention is firmly attached to the adsorption port even when the surface of the adherend surface 1 is not smooth, and the attached state is continuously maintained.
