Description

  The present invention relates to an adsorbing tool that is adsorbed to a wall surface or a plate surface of a building or the like and hooks and suspends an object.

  Conventionally, as shown in Patent Document 1, for example, this type of suction tool has a hook attached to an engaging shaft at the center of the outer surface of the suction cup, and the suction cup is pressed against a flat wall surface between the suction cup and the wall surface. Is made to be in a low pressure state, and is firmly fixed to the wall surface by the attracting force generated thereby, so that small items such as a calendar and a vase can be hung on the hook. When removing the suction tool from the wall surface, it is necessary to release the low-pressure state between the suction cup and the wall surface, so that the suction tool was removed by manually pulling the suction tool. However, since the suction cup is firmly adsorbed to the wall surface, the removal is very troublesome. Also, if the mating wall is flat, the suction cup and the wall can be held at a low pressure, but the suction cup is placed on a wall that is finely divided by a number of grooves that intersect each other, for example, when tiles are bonded together. When installing, the suction cup straddles the groove and air leaks from the groove, so that the suction cup and the wall surface cannot be held in a low pressure state, and the suction force that fixes the suction cup to the wall surface is impaired. There was a problem.

Japanese Patent Laid-Open No. 11-241717

  An object of the present invention is to provide an adsorber that can be easily detached from a wall surface and attached to the wall surface with a strong adsorbing force regardless of the shape and material of the wall surface. .

In order to achieve the above object, the structural features of the present invention include a cylindrical base portion having a shaft hole, an elastically deformable suction cup portion provided coaxially on one outer surface of the base portion, and an outer portion of the base portion. An outer deformable outer sucker portion that is coaxially provided on the side surface and covers the sucker portion, and an inner space that is elastically deformable in the axial direction and coaxially provided on the other end side of the base portion and communicates with the shaft hole. An intermediate portion having a through hole communicating with an internal space extending in the axial direction at a position opposite to the base portion in the intermediate portion, and an attachment that is detachably attached to the attachment cylindrical portion and closes the opening of the through hole And an intermediate portion between the intermediate suction cup portion and the intermediate suction cup portion, which is attached to the outer peripheral edge of the intermediate suction cup portion and is integrally attached. is that constituted by the intermediate plate portion of the hard forming a space

  In the present invention, by pressing the suction cup portion against the wall surface and pressing the mounting member, the air between the suction cup portion and the wall surface is pushed out, and the intermediate portion is also crushed in the axial direction to compress the internal space. In addition to the space between the wall portion and the wall surface, the wide portion including the inner space of the intermediate portion is brought into a low pressure state. As a result, in the present invention, a large suction force to the wall surface is generated in the suction cup portion, the suction cup portion is firmly fixed to the wall surface, and an object can be stably suspended from the attachment member of the suction tool. Further, in the present invention, when removing the suction tool, by opening the opening of the mounting cylinder part by the mounting member, air flows between the inner space, the suction cup part, and the wall surface through the through hole of the mounting cylinder part, and the suction cup part Since the low-pressure state between the wall and the wall is released, the suction tool can be easily removed from the wall.

Further, by providing an outer suction cup portion that covers the suction cup portion coaxially on the outer surface of the base portion , the outer suction cup portion and the suction cup portion are pressed against the wall surface to hold the mounting member against a normal flat wall surface. As a result, a strong suction force combining both suction cups can be obtained. Further, with respect to the wall as divided into small areas by the groove to each other as in the case of bonding the tiles, low-pressure state between the outer suction cup portion and the wall surface can not be maintained, in area than the small region smaller inner By pressing the suction cup part into a small area partitioned by a groove, the air between the suction cup part and the wall surface is pushed out, and the wide part including the suction cup part and the wall surface and the internal space of the intermediate part is brought into a low pressure state. . As a result, a large suction force to the wall surface is generated without being affected by the groove by attaching the suction cup part to the small region even on the wall surface that is finely divided into small regions by the groove, and the suction tool is firmly attached to the wall surface. Since it is fixed, an object can be stably suspended from the attachment member of the suction tool. As a result, according to the present invention, either the outer suction cup portion or the suction cup portion is fixed to the wall surface with a strong suction force according to the wall surface state, so that the suction tool is firmly fixed to the wall surface regardless of the wall surface state. Can be made.

In addition, since the intermediate portion is composed of an elastically deformable intermediate sucker portion and a hard intermediate plate portion, the intermediate sucker portion that can elastically deform the hard intermediate plate portion by pushing the mounting member. Since the intermediate portion is uniformly compressed in the axial direction, the internal space is brought into a stable low pressure state.

  In the present invention, at least one end side of the base portion can be constituted by a magnet. When the base is made of a magnet in this way, when the wall surface is made of a material that can be adsorbed by a magnet such as iron, the magnet portion comes into contact with the wall surface by pressing the outer suction cup portion and the suction cup portion against the wall surface. The suction cup is firmly fixed to the wall surface with a strong adsorption force. Moreover, an attracting tool can also be hung on a wire etc. with a magnet. As a result, according to the present invention, when the wall surface is made of a material that can be adsorbed by a magnet such as iron, the adsorber is attached by the strong adsorbing force of the magnet in addition to the adsorbing force of the outer sucker and the sucker. It can be more firmly fixed to the wall surface.

  Moreover, in this invention, the tension | tensile_strength piece protruded from the outer surface of the outer suction cup part can be provided. As a result, after the mounting member is removed from the mounting cylinder, if the suction cup is in contact with the wall surface, the low pressure state between the outer suction cup and the wall remains, but the tension piece provided on the outer suction cup is pulled. Thus, the low pressure state between the outer suction cup portion and the wall surface is easily released, and the suction tool can be easily detached from the wall surface.

In the present invention, by removing the mounting member from the mounting tube portion, air flows between the inner space, the suction cup portion, the outer suction cup portion, and the wall surface through the through hole of the mounting tube portion, and between the suction cup portion and the outer suction cup portion and the wall surface. Since the low-pressure state is released, the suction tool firmly fixed to the wall surface can be easily removed. Further, in the present invention, since at least one of the suction cup portion and the outer suction cup portion of the suction tool or the base made of a magnet is fixed to the wall surface with a strong suction force according to the state and material of the wall surface, Regardless of the material, the suction tool can be fixed to the wall surface with a strong suction force.

It is the same. In the first modification, when the wall surface is made of a material that can attract a magnet such as iron, the magnet cannot increase the attracting force with respect to the wall surface of the suction tool 10 </ b> A, but due to the action of the suction cup 14 and the outer suction cup 16. As in the above embodiment, the adsorbing tool 10A can be firmly fixed to the wall surfaces M and N. Further, the suction tool 10A according to the modified example is simpler in structure than the suction tool 10 according to the embodiment and thus is provided at a low cost. Therefore, the suction tool 10A can be effectively used according to the application.

As modification 2 of the said Example 1, as shown in FIG. 13, the whole base 12B of the adsorption tool 10B is made from a magnet. This also provides the same effect as in the first embodiment. Further, as Reference Example 1, as shown in FIG. 14, the suction tool 10 </ b> C excluding the suction cup 14 can be used, or the outer suction cup 16 can be removed. As a result, as in the first embodiment, it is impossible to cope with various states of the wall surface, but it is possible to cope with the case where the wall surface is uniform.
