Description

  The present invention relates to an adsorbent used for various purposes by adsorbing on a smooth flat surface such as a refrigerator door or a shelf of a cupboard, and more specifically, a broken object such as glass or ceramic tableware, The present invention relates to an adsorbing tool suitable for holding and storing broken objects.

Although the suction cup can be used alone, the suction force is weak only with the suction cup alone, so an suction tool that improves the suction power by combining a suction member and a suction cup that presses the suction cup toward the suction surface has been proposed. .
For example, Patent Document 1 includes a suction cup provided with a protrusion at the center of the back surface, a pressure plate that presses the suction cup, an eccentric cam piece, and a pivot that pivotally supports the eccentric cam piece on the protrusion. An adsorbed tool is described. The eccentric cam piece is provided with a cam portion provided on the peripheral edge thereof, the cam portion gradually increasing (decreasing), a locking portion engaged with the back surface of the suction cup, a lever for operation, and the like.
When the suction cup is attracted to the surface to be attracted, the lever is operated to rotate the eccentric cam piece so that the cam portion contacts the back surface of the pressure board. As a result, the pressurization plate pressurizes the peripheral edge of the suction cup, and the space volume between the suction cup and the suctioned surface increases by pulling the central part of the suction cup that is pressed flat against the suctioned surface. As a result, the pressure is lowered and a strong adsorption state is obtained. When the lever is further operated, the locking portion of the eccentric cam piece is engaged with the back surface of the pressure plate to be locked, and a stable suction state is guaranteed.

According to this invention, the 1st press part of a deformation | transformation state is attached to the axial part of the 1st suction cup adsorb | sucking to a to- be-adsorbed surface. The first pressing portion in the deformed state is attached in a state in which the opening-side end is in contact with the peripheral edge of the back surface of the first suction cup and the bottom plate is fitted in the fitting groove of the shaft portion of the first suction cup. Since the first pressing portion in the deformed state is in a state where the bottom plate and the opening side end portion are close to each other, the first pressing portion tries to restore the original natural state by the elasticity of the material of the first pressing portion. That is, the bottom plate and the opening side end portion move in directions away from each other. Thereby, the peripheral edge part of the back surface of the first suction cup is pressed toward the attracted surface by the opening side end part. Thus, the strong suction state can be maintained for a long time by pressing the peripheral part of the back surface of the first suction cup.
Similarly, the second pressing portion in a deformed state is attached to the shaft portion of the second suction cup adsorbed on the attracted surface via the shaft portion of the first suction cup. The second pressing portion in the deformed state has an opening side end in contact with the peripheral edge of the back surface of the second suction cup, and a bottom plate attached to the shaft portion of the second suction cup via the shaft portion of the first suction cup. Become. Since the 2nd press part of a deformation | transformation state is a state which the bottom plate and the opening side edge part adjoined, it tries to restore | restore to an original natural state with the elasticity which the material of a 2nd press part has. That is, the bottom plate and the opening side end portion move in directions away from each other. As a result, the peripheral edge of the back surface of the second suction cup is pressed toward the attracted surface by the opening side end. Thus, the strong suction state can be maintained for a long time by pressing the peripheral part of the back surface of the second suction cup.
Thus, the 1st and 2nd suction cups arrange | positioned in the mutually reverse direction can be adsorb | sucked in a strong adsorption state over a long time with respect to each to-be-adsorbed surface, respectively.
Such an adsorber, for example, when storing tableware in a cupboard, makes it easy to adsorb the first sucker to the shelf of the cupboard and to adsorb the bottom surface of the tableware to the second cup. Can be stored in a cupboard. Thereby, for example, when an earthquake occurs, it is possible to prevent the tableware from moving and sliding down or colliding with other tableware and cracking. Moreover, since the tableware can be further fixed on the upper surface of the tableware fixed using the suction tool, the plurality of tableware can be stacked and fixed.
Further, the suction tool is composed of only three parts, two suction cups and one pressing member, and the pressing member is attached to the shaft portion of the first suction cup and only the shaft portion of the second suction cup is mounted. Since it can assemble | assemble, it can assemble easily and reduction of manufacturing cost is attained. Moreover, since both the two suction cups and one pressing member have a relatively simple structure, they can be manufactured at a relatively low cost, and the manufacturing cost can be reduced also in this respect.

Moreover, according to this invention, the 1st press member of a deformation | transformation state is attached to the axial part of the 1st suction cup attracted | sucked to the to-be-sucked surface. The first pressing member in the deformed state is attached in a state in which the opening-side end is in contact with the peripheral edge of the back surface of the first suction cup and the bottom plate is fitted to the shaft portion of the first suction cup. Since the first pressing member in the deformed state is in a state where the bottom plate and the opening side end portion are close to each other, the first pressing member tries to restore the original natural state by the elasticity of the material of the first pressing member. That is, the bottom plate and the opening side end portion move in directions away from each other. As a result, the peripheral edge portion of the back surface of the first suction cup is pressed toward the attracted surface by the opening-side end portion, and the shaft portion of the first sucker is pulled in a direction away from the attracted surface by the bottom plate. Thus, while the peripheral part of the back surface of the 1st suction cup is pressed and the shaft part of the 1st suction cup is pulled in the direction away from the attracted face, it is between the attracted face and the attracted face of the first sucker. The space becomes a negative pressure state, and a strong adsorption state can be maintained for a long time.
Similarly, a deformed second pressing member is attached to the shaft portion of the second suction cup adsorbed on the attracted surface. The second pressing member in the deformed state is attached in a state in which the opening-side end is in contact with the peripheral edge of the back surface of the second suction cup and the bottom plate is fitted in the fitting groove of the shaft portion of the second suction cup. Since the second pressing member in the deformed state is in a state where the bottom plate and the opening side end portion are close to each other, the second pressing member attempts to restore the original natural state by the elasticity of the material of the second pressing member. That is, the bottom plate and the opening side end portion move in directions away from each other. As a result, the peripheral edge of the back surface of the second suction cup is pressed toward the attracted surface by the opening side end, and the shaft portion of the second sucker is pulled in the direction away from the attracted surface by the bottom plate. Thus, while the peripheral part of the back surface of the second suction cup is pressed and the shaft part of the second suction cup is pulled away from the attracted surface, it is between the attracted surface and the attracted surface of the second sucker. The space becomes a negative pressure state, and a strong adsorption state can be maintained for a long time.
Thus, the 1st and 2nd suction cups arrange | positioned in the mutually reverse direction can be adsorb | sucked in a strong adsorption state over a long time with respect to each to-be-adsorbed surface, respectively.
Such an adsorber, for example, when storing tableware in a cupboard, makes it easy to adsorb the first sucker to the shelf of the cupboard and to adsorb the bottom surface of the tableware to the second cup. Can be stored in a cupboard. Thereby, for example, when an earthquake occurs, it is possible to prevent the tableware from moving and sliding down or colliding with other tableware and cracking. Moreover, since the tableware can be further fixed on the upper surface of the tableware fixed using the suction tool, the plurality of tableware can be stacked and fixed.

  In addition, since the first and second pressing members are configured to be separable / connectable, the first and second pressing members are connected after the first and second suction cups are attracted to the object (surface to be attracted), respectively. It is possible to perform the operation of adsorbing the first and second suction cups to the object (surface to be adsorbed) more reliably. In addition, since the first and second suction cups can be peeled off from the object (surface to be attracted) after separating the first and second pressing members, the first and second suction cups are removed from the object (surface to be attracted). The peeling operation can be easily performed.

  The suction tool is composed of only four parts including two suction cups and two pressing members. The first pressing member is attached to the shaft portion of the first suction cup, and the second pressing member is attached to the shaft portion of the second suction cup. Can be assembled simply by connecting the first pressing member and the second pressing member, and therefore, it can be easily assembled and the manufacturing cost can be reduced. Moreover, since both the two suction cups and the two pressing members have a relatively simple structure, they can be manufactured at a relatively low cost, and the manufacturing cost can be reduced also in this respect.

  According to the present invention, since the length can be changed in the direction in which the bottom plates of the first and second pressing members approach / separate, the length between the suction surfaces of the first and second suction cups can be changed. it can. Accordingly, the length between the suction surfaces of the first and second suction cups can be changed and used according to the type of the object to be sucked by the first and second suction cups. For example, when storing a mug upside down in a cupboard, set the length between the suction surfaces of the first and second suction cups to be longer than the depth of the mug and place one suction cup on the cupboard shelf. By adsorbing and sucking the other suction cup on the inner bottom surface of the mug, it can be stored upside down without contacting the shelf. In this way, the length between the suction surfaces of the first and second suction cups can be changed according to the depth of the mug. That is, since the length between the suction surfaces of the first and second suction cups can be changed according to the purpose of use, the range of use is expanded and the convenience is improved.

Moreover, according to this invention, the 1st press part of a deformation | transformation state is attached to the axial part of the 1st suction cup attracted | sucked to the to-be-sucked surface. The first pressing portion in the deformed state is attached in a state in which the opening-side end is in contact with the peripheral edge of the back surface of the first suction cup and the bottom plate is fitted in the fitting groove of the shaft portion of the first suction cup. Since the first pressing portion in the deformed state is in a state where the bottom plate and the opening side end portion are close to each other, the first pressing portion tries to restore the original natural state by the elasticity of the material of the first pressing portion. That is, the bottom plate and the opening side end portion move in directions away from each other. As a result, the peripheral edge portion of the back surface of the first suction cup is pressed toward the attracted surface by the opening-side end portion, and the shaft portion of the first sucker is pulled in a direction away from the attracted surface by the bottom plate. Thus, while the peripheral part of the back surface of the 1st suction cup is pressed and the shaft part of the 1st suction cup is pulled in the direction away from the attracted face, it is between the attracted face and the attracted face of the first sucker. The space becomes a negative pressure state, and a strong adsorption state can be maintained for a long time.
Similarly, a deformed second pressing portion is attached to the shaft portion of the second suction cup that is adsorbed to the attracted surface. The second pressing portion in the deformed state is attached in a state where the opening side end abuts the peripheral edge of the back surface of the second suction cup and the bottom plate is fitted in the fitting groove of the shaft portion of the second suction cup. Since the 2nd press part of a deformation | transformation state is a state which the bottom plate and the opening side edge part adjoined, it tries to restore | restore to an original natural state with the elasticity which the material of a 2nd press part has. That is, the bottom plate and the opening side end portion move in directions away from each other. As a result, the peripheral edge of the back surface of the second suction cup is pressed toward the attracted surface by the opening side end, and the shaft portion of the second sucker is pulled in the direction away from the attracted surface by the bottom plate. Thus, while the peripheral part of the back surface of the second suction cup is pressed and the shaft part of the second suction cup is pulled away from the attracted surface, it is between the attracted surface and the attracted surface of the second sucker. The space becomes a negative pressure state, and a strong adsorption state can be maintained for a long time.
Thus, the 1st and 2nd suction cups arrange | positioned in the mutually reverse direction can be adsorb | sucked in a strong adsorption state over a long time with respect to each to-be-adsorbed surface, respectively.
Such an adsorber, for example, when storing tableware in a cupboard, makes it easy to adsorb the first sucker to the shelf of the cupboard and to adsorb the bottom surface of the tableware to the second cup. Can be stored in a cupboard. Thereby, for example, when an earthquake occurs, it is possible to prevent the tableware from moving and sliding down or colliding with other tableware and cracking.
Moreover, since the tableware can be further fixed on the upper surface of the tableware fixed using the suction tool, the plurality of tableware can be stacked and fixed.
Further, the suction tool is composed of only three parts including two suction cups and one connecting member, the first pressing part is attached to the shaft part of the first suction cup, and the second pressing part is attached to the shaft part of the second suction cup. Since it can be assembled simply by attaching, it can be easily assembled and the manufacturing cost can be reduced. In addition, since both the suction cups and one connecting member have a relatively simple structure, they can be manufactured at a relatively low cost, and the manufacturing cost can also be reduced in this respect.

  Further, according to the present invention, when a part of the suction cup is peeled off from the suction surface by pinching the protrusion, air enters between the suction surface and the suction surface of the suction cup from the peeled portion, so that the suction cup can be easily attached to the suction surface. Can be removed from. If the suction cup is attracted to the suction surface so that the protrusion is positioned outside the notch, the suction state corresponding to the notch is not pressed and the suction state is weaker than other parts. A part of the suction cup corresponding to the notch can be easily peeled off.

The suction cup body 4 is formed in a substantially disk shape, and one surface in the thickness direction is formed in a concave shape to form a suction surface 4a. The suction surface 4a is formed in a spherical shape so that the center of the substantially disc-shaped suction cup body 4 is lowest. The other surface in the thickness direction, that is, the back surface 4b opposite to the suction surface 4a is formed in a convex shape. The back surface 4b is formed in a spherical shape so that the center of the substantially disc-shaped suction cup body 4 is the highest.

A shaft portion 5 is formed on the back surface 4 b of the suction cup body 4. The shaft portion 5 is formed in a substantially cylindrical shape, and is formed on the back surface 4 b of the suction cup body 4 so that the axis of the shaft section 5 passes through the center of the suction cup body 4. A fitting groove 5 a is formed on the side surface of the shaft portion 5 over the entire circumference. The pressing member 3 is attached to the fitting groove 5a. Therefore, the width (length in the axial direction) W1 of the fitting groove 5a is set to be about 1 mm larger than the thickness W2 of the bottom plate 7 of the pressing member 3.
Further, a knob portion 6 is formed on the outer periphery of the suction cup body 4. The knob portion 6 includes a plate-like support portion 6a formed outwardly extending from the peripheral edge portion of the suction cup body 4, and a projection portion 6b formed on the surface of the support portion 6a on the shaft portion 5 side. . The protrusion 6b is a columnar member formed to extend parallel to the axis of the shaft 5 and has a hemispherical tip. The protrusion 6b is a pinch by the user when the suction cup 2 is peeled off from the attracted surface S1.

The pressing member 3 is a substantially bowl-shaped member made of a synthetic resin such as plastic, and includes a bottom plate 7 and side plates 8.

By forming the notch 10, the pressing member 3 can be easily deformed. That is, when the bottom plate 7 is pressed against the opening-side end 8a against the pressing member 3 in the natural state shown in FIG. 4A, the notch 10 opens and the bottom plate as shown in FIG. 4B. 7 is bent toward the opening end 8a, and the bottom plate 7 and the opening end 8a are in a deformed state.
In addition, the fitting groove 5a of the shaft part 5 is from the back surface 4b when the suction surface 4a of the suction cup 2 is attracted to the attracted surface S1 (more precisely, the position where the opening side end portion 8a is in contact). In the fitting groove 5, the length L2 to the side surface 5a2 facing the back surface 4b is formed at a position smaller than the length L1 from the opening side end 8a to the bottom plate 7 in the natural state of the pressing member 3. . Therefore, when the suction cup 2 is attracted to the attracted surface S1, the pressing member 3 attached to the shaft portion 5 of the suction cup 2 is maintained in a deformed state.

FIG. 5 is a cross-sectional view showing a procedure for adsorbing the adsorbing tool 1 to the attracted surface S1.
First, as shown in FIG. 5A, the pressing member 3 is attached to the shaft portion 5 of the suction cup 2. More specifically, since the diameter D2 of the fitting hole 7a of the bottom plate 7 is set smaller than the outer diameter D3 of the shaft portion 5 as described above, the shaft portion 5 formed of a soft material is compressed. Is pushed into the fitting hole 7a of the bottom plate 7 of the pressing member 3, and when the bottom plate 7 is fitted until reaching the fitting groove 5a of the shaft portion 5, the compressed state of the shaft portion 5 is released. As described above, the width W1 of the fitting groove 5a is larger than the thickness W2 of the bottom plate 7, and the outer diameter D4 of the bottom surface portion 5a1 of the fitting groove 5a is smaller than the diameter D2 of the fitting hole 7a of the bottom plate 7. The pressing member 3 is attached to the suction cup 2 in a state where the bottom plate 7 is fitted in the fitting groove 5 a of the portion 5. The pressing member 3 at this time is in a natural state as shown in FIG.

Next, as shown in FIG. 5 (b), the suction cup 2 is pressed against the suction surface S1 together with the pressing member 3, and the suction surface 4a of the suction cup 2 is attracted to the suction surface S1. Here, as described above, the fitting groove 5a is a length from the back surface 4b when the suction surface 4a of the suction cup 2 is attracted to the suctioned surface S1 to the side surface 5a2 facing the back surface 4b in the fitting groove 5a. The length L <b> 2 is formed at a position smaller than the length L <b> 1 from the opening side end 8 a to the bottom plate 7 in the natural state of the pressing member 3. Therefore, a force is applied to the pressing member 3 so that the bottom plate 7 and the opening side end portion 8a are close to each other by the side surface 5a2 facing the back surface 4b of the fitting groove 5a and the back surface 4b of the suction cup body 4. Become. As a result, as shown in FIG. 4B, the pressing member 3 is in a deformed state in which the notch 10 is opened and the bottom plate 7 is bent toward the opening end 8a, and the bottom plate 7 and the opening end 8a are close to each other. Become.
The pressing member 3 in such a deformed state is attached so that the bottom plate 7 is fitted in the fitting groove 5a of the shaft portion 5 and the opening-side end portion 8a is in contact with the peripheral edge portion of the back surface 4b of the suction cup body 4. Will be. At this time, the deformed pressing member 3 tends to be restored to its natural state by the elasticity of the material of the pressing member 3. For this reason, the opening side end 8a presses the peripheral edge of the back surface 4b of the suction cup body 4 toward the attracted surface S1 by the pressing member 3 that is to be restored from the deformed state to the natural state, and the bottom plate 7 is the suction cup 2. A force is applied in a direction in which the shaft portion 5 is separated from the attracted surface S1.
In this way, the peripheral portion of the suction cup body 4 is pressed against the attracted surface S1, and the shaft portion 5 of the sucker 2 is pulled away from the attracted surface S1, thereby attracting the attracted surface 4a of the sucker 2 and the attracted surface. The space between the surface S1 is in a negative pressure state, and a strong adsorption state can be maintained for a long time.

As described above, according to the first embodiment, when the suction surface 4a of the suction cup 2 is attracted to the suction target surface S1, the suction cup main body 4 is provided with the deformed pressing member 3 attached to the suction cup 2. Are pressed against the attracted surface S1, and the shaft portion 5 of the suction cup 2 is pulled away from the attracted surface S1. Thereby, the space between the suction surface 4a of the suction cup 2 and the suctioned surface S1 is in a negative pressure state, and a strong suction state can be maintained for a long time.
Also, the suction tool 1 is composed of only two parts, one suction cup 2 and one pressing member 3, and can be assembled simply by attaching the pressing member 3 to the shaft portion 5 of the suction cup 2. As a result, the manufacturing cost can be reduced. Further, since both the suction cup 2 and the pressing member 3 have a relatively simple structure, they can be manufactured at a relatively low cost, and the manufacturing cost can be reduced also in this respect.
For example, if the suction tool 1 is used by attaching a hook to the shaft portion 5 of the suction cup 2 and adsorbing the suction cup 2 to the door of a refrigerator or a cupboard, various objects can be hung or hung on the hook. it can. In addition, since a strong suction state is realized, it is possible to hang or hang an object that is heavier than the suction cup 2 alone.
Further, a knob portion 6 is formed on the outer periphery of the suction cup body 4, and when a part of the suction cup body 4 is peeled off from the attracted surface S1 by pinching the protrusion 6b of the knob portion 6, the suction cup 2 is removed from the peeled portion. Since air enters between the suction surface 4a and the suction surface S1, the suction cup 2 can be easily detached from the suction surface S1. In addition, if the suction cup 2 is attracted to the attracted surface S1 so that the knob portion 6 is positioned outside the notch 10, a part of the suction cup 2 corresponding to the notch 10 is not pressed, so that it is compared with other parts. Since the suction state is weak, a part of the suction cup 2 corresponding to the notch 10 can be easily peeled off.

  FIG. 6 is a side view showing the configuration of the suction tool 11 according to the second embodiment of the present invention. 7A and 7B are views showing the shape of the first suction cup 12, wherein FIG. 7A is a plan view, and FIG. 7B is a cross-sectional view as viewed from the cutting plane line b3-b3 of FIG. 8A and 8B are diagrams showing the shape of the second suction cup 13, wherein FIG. 8A is a plan view, and FIG. 8B is a cross-sectional view as viewed from the cutting plane line b4-b4 of FIG. 9A and 9B are diagrams showing the shape of the pressing member 14, wherein FIG. 9A is a plan view, and FIG. 9B is a cross-sectional view as seen from the cutting plane line b5-b5 in FIG.

The suction tool 11 includes a first suction cup 12, a second suction cup 13, and a pressing member 14.
The first suction cup 12 is similar to the suction cup 2 of the first embodiment, and the same components are denoted by the same reference numerals and detailed description thereof is omitted. The first suction cup 12 is different from the suction cup 2 in that a fitting structure for fitting the shaft portion of the second suction cup 13 is formed in the shaft portion 5. A detailed description of the fitting structure will be described later.

The second suction cup 13 includes a suction cup body 15, a shaft portion 16, and a knob portion 17, and the suction cup body 15, the shaft portion 16 and the knob portion 17 are integrally formed of a soft material. The suction cup body 15 is formed in a substantially disc shape, and one surface in the thickness direction is formed in a concave shape to form a suction surface 15a. The suction surface 15a is formed in a spherical shape so that the center of the disk is lowest. Further, the other surface in the thickness direction, that is, the back surface 15b opposite to the suction surface 15a is formed in a convex shape. The back surface 15b is formed in a spherical shape so that the center of the disk is the highest.
A shaft portion 16 is formed on the back surface 15 b of the suction cup body 15. The shaft portion 16 includes a base portion 16a, a columnar portion 16b, and projecting portions 16c and 16d.
The base portion 16 a is formed in a disc shape, and is formed on the back surface 15 b of the suction cup body 15 so that its axis passes through the center of the suction cup body 15. The columnar portion 16 b is connected to the base portion 16 a so that its axis passes through the center of the suction cup body 15. The protruding portions 16c and 16d are side portions on the distal end side of the cylindrical portion 16b, and are formed at positions facing each other with the cylindrical portion 16b interposed therebetween. The protruding portions 16c and 16d are formed in a substantially plate shape, and the thickness thereof is formed so as to increase from the tip toward the base portion 16a.

Further, a knob portion 17 is formed on the outer periphery of the suction cup body 15. The knob portion 17 includes a plate-like support portion 17a formed outwardly extending from the peripheral portion of the suction cup body 15, and a projection portion 17b formed on the surface of the support portion 17a on the shaft portion 16 side. . The protrusion 17b is a columnar member formed to extend parallel to the axis of the shaft portion 16, and has a hemispherical tip. The protrusion 17b is a pinch by the user when the second suction cup 13 is peeled off from the attracted surface S2.
Here, the fitting structure of the shaft portion 5 of the first suction cup 12 is such that the guide hole 18 for guiding the shaft portion 16 of the second suction cup 13 and the tip portion (protrusion portion 16c) of the shaft portion 16 of the second suction cup 13 are used. , 16d) is stored in the storage space 19. The planar shape of the guide hole 18 is the same as the planar shape of the tip portion of the shaft portion 16 of the second suction cup 13, and the substantially rectangular portion 18b disposed at a position facing the circular portion 18a and the circular portion 18a. , 18c. The guide hole 18 is formed along the axis of the shaft portion 5 from the tip of the shaft portion 5 of the first suction cup 12 toward the suction cup body 4, and extends from the base portion 16a of the second suction cup 13 to the protruding portions 16c and 16d. The length is the same as the length.

The storage space 19 communicates with the guide hole 18 and is formed in a columnar shape. The diameter of the columnar space is the length of the guide hole 18 in the longitudinal direction (the length between the substantially rectangular portions 18b and 18c). The height of the columnar space is set to be greater than the length of the tip portion of the shaft portion 16 of the second suction cup 13 (including the protruding portions 16c and 16d).
By forming the guide hole 18 and the storage space 19 constituting the fitting structure as described above, until the shaft portion 16 of the second suction cup 13 is inserted into the guide hole 18 and the projecting portions 16 c and 16 d reach the storage space 19. After the insertion, the shaft portion 16 of the second suction cup 13 can be rotated around the axis. Therefore, when the shaft portion 16 of the second suction cup 13 is rotated 90 degrees after the projection portions 16c and 16d are inserted until they reach the storage space 19, the projection portions 16c and 16d are moved to the inner wall (the guide hole 18 and the storage space). The shaft portion 16 of the second suction cup 13 can be fitted without being detached from the shaft portion 5 of the first suction cup 12.

The pressing member 14 is a member formed of a synthetic resin such as plastic. In general, two pressing members 3 according to the first embodiment described above are prepared, and the bottom plates 7 of the pressing members 3 are joined to each other. Although it is the same as the shape, to be precise, the first pressing portion 21 and the second pressing portion 22 each having a substantially bowl shape are respectively formed on both sides of one disc-shaped bottom plate 20.
A fitting hole 20 a into which the shaft portion 5 of the first suction cup 12 is fitted is formed at the center of the disc-shaped bottom plate 20. On one side of the bottom plate 20, a substantially plate-shaped first pressing portion 21 is formed by forming a side plate 23. That is, the first pressing portion 21 is composed of the bottom plate 20 and the side plate 23. The side plate 23 is formed in a substantially cylindrical shape. More specifically, the side plate 23 has a diameter (as it goes away from the bottom plate 20, that is, from one end connected to the bottom plate 20 to the other end (opening side end) 23 a. The inner diameter is increased. An inner diameter D <b> 11 of the opening side end 23 a of the first pressing portion 21 is set smaller than the outer diameter of the first suction cup 12.
The opening-side end portion 23a is bent outward and is formed in a so-called collar shape. That is, the opening-side end portion 23 a is a portion that is formed in a substantially annular shape over the entire circumference of the side plate 23, and is a plate-like portion that is formed to extend outward from the side plate 23.
The diameter D12 of the fitting hole 20a of the bottom plate 20 is set to be smaller than the outer diameter D3 of the shaft portion 5 of the first suction cup 12, and from the outer diameter D4 of the columnar portion that becomes the bottom surface 5a1 of the fitting groove 5a. It is set large.

Further, the first pressing portion 21 is formed with one notch 24 extending in a band shape toward the center of the bottom plate 20 from the opening side end portion 23a to the fitting hole 20a of the bottom plate 20. By forming this notch 24, the 1st press part 21 becomes easily deformable like the press member 3 of 1st Embodiment. That is, when the bottom plate 20 is pressed toward the opening end 23a against the first pressing portion 21 in the natural state shown in FIG. 9, the notch 24 is opened and the bottom plate 20 is opened as shown in FIG. Is bent toward the opening-side end portion 23a, and the bottom plate 20 and the opening-side end portion 23a are brought into a deformed state.
The fitting groove 5a of the shaft portion 5 is a back surface 4b when the suction surface 4a of the first suction cup 12 is attracted to the attracted surface S1 (precisely, the position where the opening side end portion 23a is in contact) ) To the side surface 5a2 facing the back surface 4b of the fitting groove 5 at a position smaller than the length L11 from the opening side end 23a to the bottom plate 20 in the natural state of the first pressing portion 21. Is formed. Therefore, when the 1st suction cup 12 is adsorb | sucking to the to-be-adsorbed surface S1, the 1st press part 21 attached to the axial part 5 of the 1st suction cup 12 will be maintained in a deformation | transformation state.

Further, on the other side of the bottom plate 20, a side plate 25 is formed to form a substantially bowl-shaped second pressing portion 22. The side plate 25 is formed in a substantially cylindrical shape. More specifically, the side plate 25 has a diameter (as it goes away from the bottom plate 20, that is, from one end connected to the bottom plate 20 to the other end (opening side end) 25 a. The inner diameter is increased. An inner diameter D13 of the opening side end portion 25a of the second pressing portion 22 is set smaller than the outer diameter of the second suction cup 13.
The opening-side end portion 25a is bent outward and formed into a so-called collar shape. That is, the opening-side end portion 25a is a portion formed in a substantially annular shape over the entire circumference of the side plate 25, and is a plate-like portion formed extending outward.

Further, the second pressing portion 22 is formed with one notch 26 extending in a strip shape toward the center of the bottom plate 20 from the opening side end portion 25a to the fitting hole 20a of the bottom plate 20. By forming this notch 26, the second pressing portion 22 can be easily deformed, like the pressing member 3 of the first embodiment. That is, when the bottom plate 20 is pressed toward the opening-side end portion 25a against the second pressing portion 22 in the natural state shown in FIG. 9, the notch 26 is opened and the bottom plate 20 is opened as shown in FIG. Is bent toward the opening side end 25a, and the bottom plate 20 and the opening side end 25a are brought into a deformed state.
In addition, the fitting groove 5a of the shaft portion 5 is a back surface 15b when the suction surface 15a of the second suction cup 13 is attracted to the attracted surface S2. ) To the side surface 5a3 facing the back surface 15b of the fitting groove 5 at a position where the length L13 from the opening side end 25a to the bottom plate 20 in the natural state of the second pressing portion 22 is smaller than the length L14. Is formed. Therefore, when the 2nd suction cup 13 is adsorb | sucking to the to-be-adsorbed surface S2, the 2nd press part 22 attached to the axial part 5 of the 1st suction cup 12 will be maintained in a deformation | transformation state.

  Further, as shown in FIG. 10 (b), the fitting groove 5a is configured so that the suction surfaces 4a and 15a of the suction cups 12 and 13 are attracted to the suction faces S1 and S2 with respect to the first and second suction cups 12 and 13, respectively. The length from the back surface 4b, 15b to the side surface 5a2, 5a3 facing the back surface 4b, 15b in the fitting groove 5a is the opening side end in the natural state of the first and second pressing portions 21, 22 It is formed at a position smaller than the length from 23a, 25a to the bottom plate 20.

Next, a procedure for sucking the suction tool 11 to the suction surfaces S1 and S2 will be described with reference to FIG.
First, as shown in FIG. 10A, the pressing member 14 is attached to the shaft portion 5 of the first suction cup 12. More specifically, since the diameter D12 of the fitting hole 20a of the bottom plate 20 is set smaller than the outer diameter D13 of the shaft portion 5 as described above, the shaft portion 5 formed of a soft material is compressed. Is pushed into the fitting hole 20a of the bottom plate 20 of the pressing member 14, and when the bottom plate 20 is fitted until reaching the fitting groove 5a of the shaft portion 5, the compressed state of the shaft portion 5 is released. As described above, the width W1 of the fitting groove 5a is larger than the thickness W2 of the bottom plate 20, and the outer diameter D4 of the bottom surface portion 5a1 of the fitting groove 5a is smaller than the diameter D12 of the fitting hole 20a of the bottom plate 20. The pressing member 14 is attached to the first suction cup 12 with the bottom plate 20 fitted in the fitting groove 5 a of the portion 5. The pressing member 14 at this time is in a natural state.

Next, as shown in FIG. 10B, the shaft portion 16 of the second suction cup 13 is inserted into the shaft portion 5 of the first suction cup 12, and the pressing member 14 is sandwiched between the first suction cup 12 and the second suction cup 13. In this state, the suction surface 4a of the first suction cup 12 is pressed against the suction surface (for example, the top surface of the shelf) S1 of the first object, and the suction surface 15a of the second suction cup 13 is pressed against the suction surface of the second object. (For example, the bottom surface of the mug) The suction surfaces 4a and 15a of the first and second suction cups 12 and 13 are pressed against the surface S2 by applying a force so that the first object and the second object are close to each other. Adsorb to S1 and S2. Thereafter, either the first or second object is rotated 90 degrees to connect the first and second suction cups 12 and 13.
Here, as shown in FIG. 10B, the fitting groove 5a has suction surfaces 4a and 15a of the suction cups 12 and 13 formed on the suction faces S1 and S2 with respect to the first and second suction cups 12 and 13, respectively. The lengths L12 and L13 from the back surfaces 4b and 15b when adsorbed to the side surfaces 5a2 and 5a3 facing the back surfaces 4b and 15b in the fitting groove 5a are the opening side end portions 23a and 23a in the natural state of the pressing member 14, respectively. It is formed at a position smaller than the lengths L11 and L14 from 25a to the bottom plate 20. Therefore, the bottom plate 20 and the opening side end 23a are close to the first pressing portion 21 of the pressing member 14 by the side surface 5a2 facing the back surface 4b of the fitting groove 5a and the back surface 4b of the suction cup body 4. Power will be applied to. As a result, the first pressing portion 21 is in a deformed state in which the notch 24 is opened and the side plate 23 is bent toward the bottom plate 20 so that the bottom plate 20 and the opening-side end portion 23a are close to each other.

In the first pressing portion 21 in such a deformed state, the bottom plate 20 is fitted in the fitting groove 5a of the shaft portion 5, and the opening side end portion 23a is in contact with the peripheral edge portion of the back surface 4b of the suction cup body 4. Will be attached to. At this time, the deformed first pressing portion 21 tends to be restored to a natural state by the elasticity of the material of the first pressing portion 21. Therefore, the opening side end portion 23a presses the peripheral edge portion of the back surface 4b of the suction cup body 4 toward the attracted surface S1 by the first pressing portion 21 trying to restore the deformed state to the natural state.
Thus, since the peripheral part of the back surface 4b of the 1st suction cup 12 is pressed by the to-be-adsorbed surface S1, a strong adsorption state can be maintained over a long time.

  Further, the second pressing portion 22 of the pressing member 14 is arranged such that the bottom plate 20 and the opening side end portion 25a are close to each other by the side surface 5a3 facing the back surface 15b of the fitting groove 5a and the back surface 15b of the suction cup body 15. Power will be applied. As a result, the second pressing portion 22 is in a deformed state in which the notch 26 is opened and the side plate 25 is bent toward the bottom plate 20, and the bottom plate 20 and the opening-side end portion 25 a are close to each other.

In the second pressing portion 22 in such a deformed state, the bottom plate 20 is fitted into the fitting groove 5a of the shaft portion 5, and the opening side end portion 25a is in contact with the peripheral portion of the back surface 15b of the suction cup body 15. Will be attached to. At this time, the deformed second pressing portion 22 tends to be restored to a natural state by the elasticity of the material of the second pressing portion 22. Therefore, the opening side end portion 25a presses the peripheral edge portion of the back surface 15b of the suction cup body 15 toward the attracted surface S2 by the second pressing portion 22 trying to restore the deformed state to the natural state.
Thus, since the peripheral part of the back surface 15b of the 2nd suction cup 13 is pressed by the to-be-adsorbed surface S2, a strong adsorption state can be maintained over a long time.

By the way, depending on how the force is applied to the pressing member 14, the bottom plate 20 may be bent toward the first suction cup 12 side or the second suction cup 13 side. For example, as shown in FIG. 10B, when the bottom plate 20 is bent toward the first suction cup 12, the bottom plate 20 applies a force in a direction to separate the shaft portion 5 of the first suction cup 12 from the attracted surface S1. Will act. In this case, the space between the suction surface 4a of the first suction cup 12 and the suction surface S1 is in a negative pressure state by the shaft portion 5 of the first suction cup 12 being pulled away from the suction surface S1. Thus, it is possible to maintain a stronger suction state for a longer time than when only the peripheral edge of the back surface 4b of the first suction cup 12 is pressed.
Further, when the bottom plate 20 is bent toward the second suction cup 13, the bottom plate 20 exerts a force in a direction to separate the shaft portion 16 of the second suction cup 13 from the attracted surface S <b> 2 via the shaft portion 5 of the first suction cup 12. Will act. In this case, the space between the suction surface 15a of the second suction cup 13 and the suction surface S2 is brought into a negative pressure state by the shaft portion 16 of the second suction cup 13 being pulled away from the suction surface S2. Thus, it is possible to maintain a stronger suction state for a longer time than when only the peripheral edge of the back surface 15b of the second suction cup 13 is pressed.
If the bottom plate 20 is not bent, the force for separating the shaft portion 5 of the first suction cup 12 from the attracted surface S1 and the force for separating the shaft portion 16 of the second sucker 13 from the attracted surface S2 are as follows. Does not work.

As described above, according to the second embodiment, the first and second suction cups 12 and 13 arranged in opposite directions are attracted to the attracted surfaces S1 and S2 in a strong adsorption state for a long time. Can be made.
For example, when storing such a suction tool 11 in a cupboard, the first suction cup 12 is sucked to the shelf of the cupboard and the second suction cup 13 is used to suck the bottom of the tableware. Tableware can be easily fixed and stored in the cupboard. Thereby, for example, when an earthquake occurs, it is possible to prevent the tableware from moving and sliding down or colliding with other tableware and cracking. Moreover, since the tableware can be further fixed using the suction tool 11 on the upper surface of the tableware fixed using the suction tool 11, a plurality of tableware can be stacked and fixed.

  The suction tool 11 is composed of only three parts, ie, two suction cups 12 and 13 and one pressing member 14. The pressing member 14 is attached to the shaft portion 5 of the first suction cup 12 and the second suction cup 13. Since it can be assembled simply by mounting the shaft portion 16, it can be easily assembled, and the manufacturing cost can be reduced. In addition, since the two suction cups 12 and 13 and the one pressing member 14 have a relatively simple structure, they can be manufactured at a relatively low cost, and the manufacturing cost can be reduced also in this respect.

  FIG. 11 is a side view showing the configuration of the suction tool 31 according to the third embodiment of the present invention. 12A and 12B are views showing the shape of the first pressing member 34, where FIG. 12A is a plan view, and FIG. 12B is a cross-sectional view taken along the section line b6-b6 in FIG. 13A and 13B are views showing the shape of the second pressing member 35, where FIG. 13A is a plan view, FIG. 13B is a cross-sectional view taken along the cutting plane line b7-b7 in FIG. ) Is a cross-sectional view taken along section line b8-b8 in (a).

  The suction tool 31 includes a first suction cup 32, a second suction cup 33, a first pressing member 34, and a second pressing member 35. Since the first and second suction cups 32 and 33 are the same as the suction cup 2 of the first embodiment described above, the components of the first and second suction cups 32 and 33 are denoted by the same reference numerals and will be described in detail. Is omitted. Moreover, since the 1st and 2nd press members 34 and 35 are the structures similar to the press member 3 of 1st Embodiment mentioned above, the same referential mark is attached | subjected to the same component and detailed description is abbreviate | omitted. .

The first pressing member 34 includes a first pressing portion 34a having the same structure as the pressing member 3 of the first embodiment, and a first connecting portion 34b formed on the side opposite to the side plate 8 of the bottom plate 7 of the first pressing portion 34a. It consists of and. Moreover, the 2nd press member 35 is the 2nd connection part formed in the opposite side to the side plate 8 of the 2nd press part 35a of the same structure as the press member 3 of 1st Embodiment, and the bottom plate 7 of the 2nd press part 35a. It is comprised with the part 35b.
In 3rd Embodiment, the 1st and 2nd connection parts 34b and 35b are provided in the 1st and 2nd press members 34 and 35, respectively, and the 1st and 2nd by the 1st and 2nd connection parts 34b and 35b. The pressing members 34 and 35 are configured to be separable / connectable. Further, the first and second connecting portions 34b and 35b of the first and second pressing members 34 and 35 are configured such that the lengths in the direction in which the first and second pressing portions 34a and 35a approach / separate each other can be changed. Has been.

  The first connecting portion 34 b of the first pressing member 34 is formed in a substantially cylindrical shape on the side (referred to as the back side) opposite to the side plate 8 of the bottom plate 7. The substantially cylindrical first connecting portion 34b is formed in a cylindrical shape having the same diameter from the bottom plate 7 to the tip, and has an opening 36 formed by cutting out the belt from the bottom plate 7 to the tip. Therefore, the cross-sectional shape of the first connecting portion 34b is substantially C-shaped. A plurality of guide grooves 37 and 38 extending in the circumferential direction from the end face facing the opening 36 are formed on both sides of the opening 36 on the inner peripheral portion of the first connecting portion 34b. The guide grooves 37 and 38 are configured by forming a recess in the inner peripheral portion of the first connecting portion 34b. Since the guide projections 37 and 38 are provided with positioning protrusions of the inner cylinder portion to be described later, the depth H21 of the guide grooves 37 and 38 is set to be equal to or higher than the height of the positioning protrusions. The length L21 is set to be equal to or greater than the circumferential length of the positioning protrusion.

  A plurality of guide grooves (generally referred to as a first guide groove group) 37 formed from one end face t1 of the two end faces t1 and t2 facing the opening 36 have the same circumferential length L21. It is formed at equal intervals. A plurality of guide grooves (generally referred to as a second guide groove group) 38 formed from the other end face t2 of the two end faces t1 and t2 have the same circumferential length as the first guide groove group 37. At the length L21, the first guide groove group 37 is formed at equal intervals at different intervals.

The second connecting portion 35 b of the second pressing member 35 includes a cylindrical portion 41 formed on the back side of the bottom plate 7, and a plate-like positioning protrusion 42 formed on the outer peripheral portion at the tip of the cylindrical portion 41. It consists of
The cylindrical portion 41 is formed in a cylindrical shape having the same diameter from the support portion 40 side to the tip. The outer diameter D21 of the cylindrical portion 41 is set to be the same as the inner diameter D22 of the first connecting portion 34b, and the length L22 of the cylindrical portion 41 is set to be the same as the length L23 of the first connecting portion 34b. . The circumferential length L24 of the positioning projection 42 is set to be equal to or less than the circumferential length L25 of the opening 36 of the first connecting portion 34b, and the positioning projection thickness (axial length) W21 is The width (circumferential length) W22 or less of the guide grooves 37, 38 of the connecting portion 34b is set. Accordingly, when the positioning protrusion 42 of the cylindrical portion 41 is aligned with the opening 36 of the first connecting portion 34b, the cylindrical portion 41 can be inserted / removed with respect to the first connecting portion 34b. Movement in the axial direction is possible in the connecting portion 34b.

  Further, if the positioning protrusion 42 of the cylindrical portion 41 is aligned with the guide grooves 37 and 38 of the first connecting portion 34b, the cylindrical portion 41 can be angularly displaced around the axis. At this time, since the positioning projections 42 are fitted in the guide grooves 37 and 38, the movement of the cylindrical portion 41 in the axial direction is restricted, and the cylindrical portion 41 is positioned at a predetermined position with respect to the first connection 34b. Can be attached. Further, since a plurality of guide grooves 37 and 38 are formed as described above, if the guide groove into which the positioning projection 42 is fitted is changed, the attachment position of the tubular portion 41 with respect to the first connecting portion 34b is changed. be able to. That is, the axial length when the first pressing member 34 and the second pressing member 35 are connected can be changed. In other words, the length from the suction surface 4a of the first suction cup 32 to the suction surface 4a of the second suction cup 33 can be changed.

  Further, as described above, since the first connecting portion 34b is formed with two guide groove groups (first and second guide grooves) 37 and 38 having different formation intervals, only one guide groove group is formed. In comparison, the attachment position of the tubular portion 41 with respect to the first connecting portion 34a can be finely changed. That is, the axial length when the first pressing member 34 and the second pressing member 35 are connected, in other words, the length from the suction surface 4a of the first suction cup 32 to the suction surface 4a of the second suction cup 33 is further increased. Can be changed finely.

Next, a procedure for sucking the suction tool 31 to the suction surfaces S1 and S2 will be described with reference to FIG.
First, the first pressing member 34 is attached to the shaft portion 5 of the first suction cup 32. More specifically, since the diameter D2 of the fitting hole 7a of the bottom plate 7 is set smaller than the outer diameter D3 of the shaft portion 5 (see FIG. 11) as in the first embodiment, it is formed of a soft material. When the shaft portion 5 is compressed, the shaft portion 5 is pressed into the fitting hole 7a of the bottom plate 7 of the first pressing member 34, and when the bottom plate 7 is fitted until reaching the fitting groove 5a of the shaft portion 5, the compression of the shaft portion 5 is performed. Release state. Here, the width W1 of the fitting groove 5a is larger than the thickness W2 of the bottom plate 7, and the outer diameter D4 of the bottom surface portion 5a1 of the fitting groove 5a is smaller than the diameter D2 of the fitting hole 7a of the bottom plate 7 (FIG. 11). The first pressing member 34 is attached to the first suction cup 32 in a state where the bottom plate 7 is fitted in the fitting groove 5 a of the shaft portion 5. At this time, the pressing portion 34a of the first pressing member 34 is in a natural state.
Similarly, the second pressing member 35 is attached to the shaft portion 5 of the second suction cup 33. The procedure is the same as that for attaching the first pressing member 34 to the shaft portion 5 of the first suction cup 32. At this time, the pressing portion 35a of the second pressing member 35 is in a natural state.

Next, the suction surface 4a of the first suction cup 32 is pressed against the suction target surface (for example, the top surface of the shelf board) S1 of the first object. Here, the fitting groove 5a formed in the shaft portion 5 of the first suction cup 32 is a back surface 4b (when the suction surface 4a of the first suction cup 32 is attracted to the suction surface S1 of the first object. The length from the opening side end 8a in the natural state of the first pressing member 34 is the length from the position where the opening side end 8a is in contact) to the side surface 5a2 facing the back surface 4b in the fitting groove 5a. It is formed at a position smaller than the length L1 to the bottom plate 7. Therefore, the bottom plate 7 and the opening-side end portion 8a are close to the first pressing portion 34a of the first pressing member 34 by the side surface 5a1 facing the back surface 4b of the fitting groove 5a and the back surface 4b of the suction cup body 4. Power will be applied to do. Accordingly, the first pressing portion 34a is in a deformed state in which the notch 10 is opened and the bottom plate 7 is bent toward the opening side end portion 8a, and the bottom plate 7 and the opening side end portion 8a are close to each other.
The first pressing portion 34 a in such a deformed state is such that the bottom plate 7 is fitted into the fitting groove 5 a of the shaft portion 5, and the opening-side end portion 8 a is in contact with the peripheral portion of the back surface 4 b of the suction cup body 4. Will be attached to. At this time, the deformed first pressing portion 34a tends to be restored to a natural state by the elasticity of the material of the first pressing portion 34a. Therefore, the opening side end portion 8a presses the peripheral edge portion of the back surface 4b of the suction cup body 4 toward the attracted surface S1 by the first pressing portion 34a trying to restore the deformed state to the natural state, and the bottom plate 7 A force is applied in a direction in which the shaft portion 5 of the first suction cup 32 is separated from the attracted surface S1.

In this way, the peripheral portion of the back surface 4b of the first suction cup 32 is pressed against the attracted surface S1, and the shaft portion 5 of the first sucker 32 is pulled in a direction away from the attracted surface S1, thereby the first sucker. The space between 32 and the attracted surface S1 is in a negative pressure state, and a strong suction state can be maintained for a long time.
Similarly, the suction surface 4a of the second suction cup 33 is pressed against the surface to be attracted (for example, the bottom surface inside the mug) S2 of the second object. As with the first suction cup 32, the second suction cup 33 can maintain a strong suction state for a long time.
Thereafter, the cylindrical portion 41 of the second connecting portion 35b of the second pressing member 35 is inserted into the first connecting portion 34b of the first pressing member 34, and the positioning protrusion 42 of the cylindrical portion 41 is inserted into the first connecting portion 34b. The desired guide groove 37 or 38 is fitted, and the length between the first suction cup 32 and the second suction cup 33 is set to a desired length. As a result, the two objects can be fixed at a desired interval.

  If such an adsorbing tool 31 is used, for example, as shown in FIG. 15, when the mug MC1 is stored in the cupboard with the drinking mouth turned upside down, the inner bottom surface B1 of the mug MC1 and the cupboard If the suction tool 31 is disposed between the upper surface Sa of the shelf plate, the mug MC1 can be fixed and stored upside down. In this case, since the length of the suction tool 31 can be changed and used, various mugs with different depths can be fixed and stored. Moreover, if the length of the adsorber 31 is set longer than the depth of the mug MC1, the drinking mouth of the mug MC1 can be stored upside down so as not to contact the upper surface Sa of the shelf.

  Further, if another suction tool 31 is disposed between the outer bottom surface B2 of the mug MC1 and the inner bottom surface B3 of the mug MC2, another mug MC2 is placed upside down on the mug MC1 fixed upside down. It can be fixed with. As a result, more mugs and cups can be fixed and stored by effectively using the space of the cupboard.

  Further, as shown in FIG. 16, when the mug MC1 is stored in the cupboard in a normal state with the drinking mouth facing upward, the suction tool 11 of the second embodiment is placed on the outer bottom surface B2 of the mug MC1 and the cupboard shelf. If it is arranged between the upper surface Sa of the plate, the mug MC1 can be fixed in the normal state and the state can be made. Furthermore, if the suction tool 31 of the third embodiment is disposed between the inner bottom surface B1 of the mug MC1 and the outer bottom surface B4 of the mug MC2, another mug MC2 is placed in the normal state on the mug MC1 fixed in the normal state. It can be fixed with.

  Furthermore, as shown in FIG. 17, another mug MC2 can be fixed in a normal state on the mug MC1 fixed in an upside down state. In this case, first, the suction tool 31 is disposed between the inner bottom surface B1 of the upside-down mug MC1 and the top surface Sa of the cupboard shelf, and the mug MC1 is fixed. Thereafter, the suction tool 11 is disposed between the outer bottom surface B2 of the upside-down mug MC1 and the outer bottom surface B4 of the normal state mug MC2 to fix the mug MC2.

As described above, according to the third embodiment, the first and second suction cups 32 and 32 arranged in opposite directions are attracted to the attracted surfaces S1 and S2 in a strong adsorption state for a long time. Can be made.
Such an adsorbing tool 31, for example, when storing tableware in a cupboard, adsorbs the first suction cup 32 to the shelf of the cupboard and uses the second suction cup 32 to adsorb the bottom surface of the tableware. Tableware can be easily fixed and stored in the cupboard. Thereby, for example, when an earthquake occurs, it is possible to prevent the tableware from moving and sliding down or colliding with other tableware and cracking. Moreover, since the tableware can be further fixed using the suction tool 31 on the upper surface of the tableware fixed using the suction tool 31, a plurality of tableware can be stacked and fixed.
Further, since the first and second pressing members 34 and 35 are configured to be connectable / separable, the first and second suction cups 32 and 33 are attracted to the objects (surfaces to be attracted) S1 and S2, respectively. The first and second pressing members 34 and 35 can be connected, and the work of sucking the first and second suction cups 32 and 33 to the object (surfaces S1 and S2) can be more reliably performed. Become. In addition, since the first and second suction members 32 and 33 can be peeled off from the object (the attracted surfaces S1 and S2) after separating the first and second pressing members 34 and 35, the first and second suckers It is possible to easily perform the work of peeling the 32 and 33 from the object (the attracted surfaces S1 and S2).

  Further, the suction tool 31 is composed of only four parts, that is, two suction cups 32 and 33 and two pressing members 34 and 35. The first pressing member 34 is attached to the shaft portion 5 of the first suction cup 32, and the first suction member 34 is attached. 2 Since the second pressing member 35 is attached to the shaft portion 5 of the suction cup 33 and then the first pressing member 34 and the second pressing member 35 can be assembled together, the assembly can be easily performed and the manufacturing cost can be reduced. Can be reduced. Further, since the two suction cups 32 and 33 and the two pressing members 34 and 35 have a relatively simple structure, they can be manufactured at a relatively low cost, and the manufacturing cost can be reduced also in this respect.

In addition, since the length can be changed in the direction in which the bottom plates 7 of the first and second pressing members 34 and 35 approach / separate each other, the suction surface 4a of the first suction cup 32 and the suction surface 4a of the second suction cup 33 The length between can be changed. Accordingly, the length between the suction surfaces 4a and 4a of the first and second suction cups 32 and 33 can be changed and used according to the type of the object to be sucked by the first and second suction cups 32 and 33. it can.
For example, as shown in FIG. 15, when the mug MC1 is stored in the cupboard upside down, the length between the suction surfaces 4a and 4a of the first and second suction cups 32 and 33 is set longer than the depth of the mug MC1. Then, one suction cup 32 (or 33) is adsorbed to the shelf of the cupboard and the other suction cup 33 (or 32) is adsorbed to the inner bottom surface B1 of the mug MC1 so as to contact the upper surface Sa of the shelf. Can be stored upside down without any problems. In this way, the length between the suction surfaces 4a, 4a of the first and second suction cups 32, 33 can be changed according to the depth of the mug. That is, since the length between the suction surfaces 4a and 4a of the first and second suction cups 32 and 33 can be changed according to the purpose of use, the range of use is widened and convenience is improved.

The second connecting portion 55 a of the second pressing member 55 includes a bottom plate 7, a substantially cylindrical second side wall portion 60 formed on the outer peripheral portion of the bottom plate 7, and a pair of engaging members 61 formed on the bottom plate 7. , 62. A strip-shaped notch 63 communicating with the notch 10 of the side plate 8 is formed in the second side wall portion 60.
The pair of engaging members 61 and 62 have the same shape, are formed at positions facing each other across the center of the bottom plate 7, and are formed so as to correspond to the pair of engaging holes 58 and 59 described above. Furthermore, it is formed so as to be point-symmetric with respect to the center of the bottom plate 7. The engaging members 61, 62 are elongated plate-like main body portions 61a, 62a extending in the axial direction of the bottom plate 7, and plate-like shapes extending from the tips of the main body portions 61a, 62a to the opposing engaging members 62, 61. It is a substantially L-shaped member composed of tip portions 61b and 62b.

  The length from the bottom plate 7 to the lower surfaces of the tip portions 61b and 62b (the surface facing the bottom plate 7) is the length of the second side wall portion 60 + the length of the first side wall portion 56 + the bottom plate 7 of the first pressing member 54. It is set to a length equal to or greater than the thickness. The inner peripheral surfaces (the side surfaces on the center side of the bottom plate 7) S7a, S8a and the outer peripheral surfaces (the side surfaces on the opposite side of the inner peripheral surface) S7b, S8b of the main body portions 61a, 62a are arcuate with respect to the center of the bottom plate 7 Is formed. Similarly, inner peripheral surfaces (side surfaces on the center side of the bottom plate 7) S9 and S10 of the tip end portion are also formed in an arc shape with respect to the center of the bottom plate 7 when viewed from the axial direction.

  The first connecting portion 54a and the second connecting portion 55a described above align the pair of engaging holes 58, 59 and the pair of engaging members 61, 62 so that the first side wall portion 56 and the second side wall portion 60 are aligned. Are connected to each other, the tip portions 61b and 62b of the pair of engaging members 61 and 62 pass through the insertion hole portions 58a and 59a of the pair of engaging holes 58 and 59 and protrude to the back side of the bottom plate 7. . In this state, when the second pressing member 55 is angularly displaced relative to the first pressing member 54 about the axis, the main body portions 61 a and 62 a of the engaging members 61 and 62 are engaged with the engaging holes 58 and 59. In addition to being fitted into the hole portions 58b and 59b, the tip end portions 61b and 62b of the engagement members 61 and 62 are brought into contact with and locked to the peripheral surfaces of the locking hole portions 58b and 59b of the bottom plate 7, so that the first connection The portion 54a and the second connecting portion 55a are prevented from separating in the axial direction. In this way, the first pressing member 54 and the second pressing member 55 can be connected.

  When separating the first pressing member 54 and the second pressing member 55, if the second pressing member 55 is angularly displaced relative to the first pressing member 54 in the axial direction in the opposite direction to that when connected, Since the main body portions 61a and 62a of the engaging members 61 and 62 are detached from the locking hole portions 58b and 59b of the engaging holes 58 and 59 and move to the insertion hole portions 58a and 59a, the distal ends of the engaging members 61 and 62 The locked state of the portions 61b and 62b is released. Thereafter, when the first pressing member 54 and the second pressing member 55 are moved away from each other, the distal end portions 61b and 62b of the engaging members 61 and 62 are inserted into the insertion hole portions 58a and 59a of the engaging holes 58 and 59, respectively. Therefore, the first pressing member 54 and the second pressing member 55 can be separated.

Next, a procedure for adsorbing the adsorbing tool 51 to the adsorbed surfaces S1 and S2 will be described.
First, the first pressing member 54 is attached to the shaft portion 5 of the first suction cup 52. More specifically, since the diameter D2 of the fitting hole 7a of the bottom plate 7 is set to be smaller than the outer diameter D3 of the shaft portion 5 (see FIG. 1) as in the first embodiment, it is formed of a soft material. When the shaft portion 5 is compressed, the shaft portion 5 is pushed into the fitting hole 7a of the bottom plate 7 of the first pressing member 54, and when the bottom plate 7 is fitted until reaching the fitting groove 5a of the shaft portion 5, the compression of the shaft portion 5 is performed. Release state. Here, the width W1 of the fitting groove 5a is larger than the thickness W2 of the bottom plate 7, and the outer diameter D4 of the bottom surface portion 5a1 of the fitting groove 5a is smaller than the diameter D2 of the fitting hole 7a of the bottom plate 7 (FIG. 1). The first pressing member 54 is attached to the first suction cup 52 in a state where the bottom plate 7 is fitted in the fitting groove 5 a of the shaft portion 5. At this time, the first pressing portion 54a of the first pressing member 54 is in a natural state.
Similarly, the second pressing member 55 is attached to the shaft portion 5 of the second suction cup 53. The procedure is the same as that for attaching the first pressing member 54 to the shaft portion 5 of the first suction cup 52. At this time, the second pressing portion 55a of the second pressing member 55 is in a natural state.

  Next, the suction surface 4a of the first suction cup 52 is pressed against the suction target surface (for example, the upper surface of the shelf board) S1 of the first object. Here, as in the first embodiment, the fitting groove 5a formed in the shaft portion 5 of the first suction cup 52 has the suction surface 4a of the first suction cup 52 attracted to the suction surface S1 of the first object. The length L52 from the back surface 4b (more precisely, the position where the opening side end 8a is in contact) to the side surface 5a2 facing the back surface 4b in the fitting groove 5a is the length of the first pressing member 54. It is formed at a position smaller than the length L51 from the opening side end 8a to the bottom plate 7 in the natural state (see FIG. 4). Therefore, the bottom plate 7 and the opening-side end portion 8a are close to the first pressing portion 54a of the first pressing member 54 by the side surface 5a1 facing the back surface 4b of the fitting groove 5a and the back surface 4b of the suction cup body 4. Power will be applied to do. Accordingly, the first pressing portion 54a is in a deformed state in which the notch 10 is opened and the bottom plate 7 is bent toward the opening end 8a, and the bottom plate 7 and the opening end 8a are close to each other.

The first pressing portion 54a in such a deformed state is such that the bottom plate 7 is fitted into the fitting groove 5a of the shaft portion 5 and the opening side end portion 8a abuts on the peripheral edge portion of the back surface 4b of the suction cup body 4. Will be attached to. At this time, the deformed first pressing portion 54a tends to be restored to the natural state by the elasticity of the material of the first pressing portion 54a. Therefore, the opening-side end 8a presses the peripheral edge of the back surface 4b of the suction cup body 4 toward the attracted surface S1 by the first pressing portion 54a trying to restore the deformed state to the natural state, and the bottom plate 7 A force is applied in a direction in which the shaft portion 5 of the first suction cup 52 is separated from the attracted surface S1.
As described above, the peripheral portion of the back surface 4b of the first suction cup 52 is pressed against the attracted surface S1, and the shaft portion 5 of the first sucker 52 is pulled away from the attracted surface S1, whereby the first sucker The space between 52 and the attracted surface S1 is in a negative pressure state, and a strong suction state can be maintained for a long time.
Similarly, the suction surface 4a of the second suction cup 53 is pressed against the surface to be attracted (for example, the bottom surface inside the mug) S2 of the second object. Similarly to the first suction cup 52, the second suction cup 53 can maintain a strong suction state for a long time.
Thereafter, the first connecting portion 54b of the first pressing member 54 and the second connecting portion 55b of the second pressing member 55 are connected. As a result, the two objects can be fixed at a predetermined interval.

As described above, according to the fourth embodiment, the first and second suction cups 52 and 53 arranged in opposite directions are attracted to the attracted surfaces S1 and S2 in a strong adsorption state for a long time. Can be made.
Such an adsorber 51, for example, when storing tableware in a cupboard, if the first suction cup 52 is adsorbed to the shelf of the cupboard and the bottom surface of the tableware is adsorbed to the second suction cup 53, Tableware can be easily fixed and stored in the cupboard. Thereby, for example, when an earthquake occurs, it is possible to prevent the tableware from moving and sliding down or colliding with other tableware and cracking. Moreover, since the tableware can be fixed further using the suction tool 51 on the upper surface of the tableware fixed using the suction tool 51, a plurality of tableware can be stacked and fixed.

  Moreover, since the 1st and 2nd press members 54 and 55 are comprised so that isolation | separation / connection is possible, after making the 1st and 2nd suction cups 52 and 53 adsorb | suck to a target object (to-be-adsorbed surface S1, S2), respectively. The first and second pressing members 54 and 55 can be connected, and the work of adsorbing the first and second suction cups 52 and 53 to the object (surfaces S1 and S2) can be more reliably performed. Become. In addition, since the first and second suction members 52 and 53 can be peeled off from the object (the attracted surfaces S1 and S2) after separating the first and second pressing members 54 and 55, the first and second suckers It is possible to easily perform the operation of peeling the 52 and 53 from the object (the attracted surfaces S1 and S2).

  Further, the suction tool 51 is composed of only four parts, ie, two suction cups 52, 53 and two pressing members 54, 55. The first pressing member 54 is attached to the shaft portion 5 of the first suction cup 52, and 2 Since the second pressing member 55 is attached to the shaft portion 5 of the suction cup 53 and then the first pressing member 54 and the second pressing member 55 can be assembled together, the assembly can be easily performed and the manufacturing cost can be increased. Can be reduced. Further, since the two suction cups 52 and 53 and the two pressing members 54 and 55 have a relatively simple structure, they can be manufactured at a relatively low cost, and the manufacturing cost can be reduced also in this respect.

The shaft portion 77 is formed in a substantially cylindrical shape, and is formed on the back surface 15 b of the suction cup body 15 so that the axis of the shaft section 77 passes through the center of the suction cup body 15. A fitting groove 77 a is formed on the side surface of the shaft portion 77 over the entire circumference. A second pressing member 75 is attached to the fitting groove 77a. Therefore, the width (length in the axial direction) W73 of the fitting groove 77a is set to be about 1 mm larger than the thickness W74 of the bottom plate 7 of the second pressing member 75.
A connecting portion 78 is formed at the tip of the shaft portion 77. The connecting portion 78 includes a base portion 78a, a columnar portion 78b, and projecting portions 78c and 78d. In addition, the structure of the connection part 78 is similar to the structure of the axial part 16 of the 2nd suction cup 13 of the above-mentioned 2nd Embodiment.
The base portion 78 a is formed in a disc shape, and is formed on the distal end surface of the shaft portion 77 so that its axis passes through the center of the suction cup body 15. The columnar portion 78 b is connected to the base portion 78 a so that its axis passes through the center of the suction cup body 15.

Further, a knob portion 17 is formed on the outer periphery of the suction cup body 15.

  Here, since the connection structure of the shaft part 76 of the first suction cup 72 is the same structure as the fitting structure of the shaft part 5 of the second suction cup 12 of the second embodiment described above, the same reference is made to the same structure. A sign is used. The guide hole 18 that guides the connecting portion 78 of the second suction cup 73 described above and the storage space 19 in which the tip end portion (the portion including the projecting portions 78c and 78d) of the connecting portion 78 of the second suction cup 73 is stored. The The planar shape of the guide hole 18 is the same as the planar shape of the distal end portion of the connecting portion 78 of the second suction cup 73, and the substantially rectangular portion 18b disposed at a position facing the circular portion 18a and the circular portion 18a. , 18c (see FIG. 7A).

The length is the same as the length.

The storage space 19 communicates with the guide hole 18 and is formed in a columnar shape. The diameter of the columnar space is the length of the guide hole 18 in the longitudinal direction (the length between the substantially rectangular portions 18b and 18c). The height of the cylindrical space is set to be greater than the length of the tip end portion (the portion including the projecting portions 78c and 78d) of the second suction cup 73.
By making the guide hole 18 and the storage space 19 constituting the fitting structure have the shapes described above, the connecting portion 78 of the second suction cup 73 is inserted into the guide hole 18 until the protruding portions 78c and 78d reach the storage space 19. After the insertion, the second suction cup 73 (connecting portion 78) can be rotated around the axis. Therefore, when the connecting portion 78 of the second suction cup 73 is rotated 90 degrees after the protrusions 78c and 78d are inserted until they reach the storage space 19, the protrusions 78c and 78d are connected to the inner wall of the storage space 19 (the guide hole 18 and the storage space). The contact portion 78 of the second suction cup 73 can be fitted without being detached from the shaft portion 76 of the first suction cup 72.

Since the first and second pressing members 74 and 75 have the same configuration as the pressing member 3 of the first embodiment described above, the same reference numerals are given to the same configuration, and detailed description thereof is omitted.
An inner diameter D71 of the opening-side end 8a of the first pressing member 74 is set smaller than the outer diameter of the suction cup body 4 of the first suction cup 72. In addition, the diameter D72 of the fitting hole 7a of the bottom plate 7 of the first pressing member 74 is set smaller than the outer diameter D73 of the shaft portion 76 of the first suction cup 72, and the cylindrical portion serving as the bottom surface of the fitting groove 76a. It is set larger than the outer diameter D74.
Further, the fitting groove 76a of the shaft portion 76 has a back surface 4b when the suction surface 4a of the first suction cup 72 is attracted to the attracted surface S1 (precisely, a position where the opening side end portion 8a is in contact). ) To the side surface of the fitting groove 75 facing the back surface 4b is formed at a position smaller than the length L72 from the opening side end 8a to the bottom plate 7 in the natural state of the first pressing member 74. Has been. Therefore, when the 1st suction cup 72 is adsorb | sucking to the to-be-adsorbed surface S1, the 1st press member 74 attached to the axial part 76 of the 1st suction cup 72 will be maintained in a deformation | transformation state.

Further, the inner diameter D75 of the opening side end 8a of the second pressing member 75 is set smaller than the outer diameter of the suction cup body 4 of the second suction cup 73. Further, the diameter D76 of the fitting hole 7a of the bottom plate 7 of the second pressing member 75 is set to be smaller than the outer diameter D77 of the shaft portion 77 of the second suction cup 73, and the cylindrical portion serving as the bottom surface of the fitting groove 77a. It is set larger than the outer diameter D78.
Further, the fitting groove 77a of the shaft portion 77 has a back surface 4b when the suction surface 4a of the second suction cup 73 is attracted to the attracted surface S2 (precisely, a position where the opening side end portion 8a is in contact). ) To the side surface facing the back surface 4b of the fitting groove 77 is formed at a position smaller than the length L74 from the opening side end 8a to the bottom plate 7 in the natural state of the second pressing member 75. Has been. Therefore, when the second suction cup 73 is attracted to the attracted surface S2, the second pressing member 75 attached to the shaft portion 77 of the second suction cup 73 is maintained in a deformed state.

Next, with reference to FIG. 22, a procedure for sucking the suction tool 71 to the suction surfaces S1 and S2 will be described.
First, the first pressing member 74 is attached to the shaft portion 76 of the first suction cup 72. More specifically, since the diameter D72 of the fitting hole 7a of the bottom plate 7 of the first pressing member 74 is set smaller than the outer diameter D73 of the shaft portion 76 as described above, the shaft portion formed of a soft material. When the bottom plate 7 is pushed into the fitting hole 7a of the bottom plate 7 of the first pressing member 74 and is fitted until the bottom plate 7 reaches the fitting groove 76a of the shaft portion 76, the compression state of the shaft portion 76 is changed. release. As described above, the width W71 of the fitting groove 76a is larger than the thickness W72 of the bottom plate 7, and the outer diameter D74 of the bottom surface portion of the fitting groove 76a is smaller than the diameter D72 of the fitting hole 7a of the bottom plate 7. The first pressing member 74 is attached to the first suction cup 72 in a state where the bottom plate 7 is fitted in the fitting groove 76 a of 76. The first pressing member 74 at this time is in a natural state.

  Next, the second pressing member 75 is attached to the shaft portion 77 of the second suction cup 73. More specifically, since the diameter D76 of the fitting hole 7a of the bottom plate 7 is set smaller than the outer diameter D77 of the shaft portion 77 as described above, the shaft portion 77 formed of a soft material is compressed. When the bottom plate 7 is pushed into the fitting hole 7a of the bottom plate 7 of the second pressing member 75 until the bottom plate 7 reaches the fitting groove 77a of the shaft portion 77, the compressed state of the shaft portion 77 is released. As described above, the width W73 of the fitting groove 77a is larger than the thickness W74 of the bottom plate 7, and the outer diameter D78 of the bottom surface portion of the fitting groove 77a is smaller than the diameter D76 of the fitting hole 7a of the bottom plate 7. The second pressing member 75 is attached to the second suction cup 73 in a state where the bottom plate 7 is fitted in the fitting groove 77 a of 77. At this time, the second pressing member 75 is in a natural state.

Next, the suction surface 4a of the first suction cup 72 is pressed against the suction surface (for example, the upper surface of the shelf board) S1 of the first object. Here, the fitting groove 76a formed in the shaft portion 76 of the first suction cup 72 has a back surface 4b (when the suction surface 4a of the first suction cup 72 is attracted to the attracted surface S1 of the first object). Exactly, the length L71 from the position where the opening side end 8a abuts to the side surface of the fitting groove 76a facing the back surface 4b is from the opening side end 8a in the natural state of the first pressing member 74. It is formed at a position smaller than the length L72 up to the bottom plate 7. Therefore, a force is applied to the first pressing member 74 so that the bottom plate 7 and the opening-side end portion 8a are close to each other by the side surface facing the back surface 4b of the fitting groove 76a and the back surface 4b of the suction cup body 4. It will be. As a result, the first pressing member 74 is in a deformed state in which the notch 10 is opened and the bottom plate 7 is bent toward the opening side end 8a, and the bottom plate 7 and the opening side end 8a are close to each other.
In the first pressing member 74 in such a deformed state, the bottom plate 7 is fitted in the fitting groove 76 a of the shaft portion 76, and the opening side end portion 8 a is in contact with the peripheral edge portion of the back surface 4 b of the suction cup body 4. Will be attached to. At this time, the deformed first pressing member 74 tends to be restored to a natural state by the elasticity of the material of the first pressing member 74. Therefore, the opening-side end 8a presses the peripheral edge of the back surface 4b of the suction cup body 4 toward the attracted surface S1 by the first pressing member 74 that tries to restore the deformed state to the natural state, and the bottom plate 7 A force is applied in a direction in which the shaft portion 76 of the first suction cup 72 is separated from the attracted surface S1.
As described above, the peripheral portion of the back surface 4b of the first suction cup 72 is pressed against the attracted surface S1, and the shaft portion 76 of the first sucker 72 is pulled in a direction away from the attracted surface S1, thereby the first sucker. The space between 72 and the attracted surface S1 is in a negative pressure state, and a strong suction state can be maintained for a long time.
Similarly, the suction surface 4a of the second suction cup 73 is pressed against the surface to be attracted (for example, the bottom surface inside the mug) S2 of the second object. Similarly to the first suction cup 72, the second suction cup 73 can maintain a strong suction state for a long time.
Thereafter, if the connecting portion 78 of the second suction cup 73 is inserted into the shaft portion 76 of the first suction cup 72 and then displaced by 90 degrees, the first suction cup 72 and the second suction cup 73 can be connected and fixed. it can. As a result, the two objects can be fixed at a predetermined interval.

As described above, according to the fifth embodiment, the first and second suction cups 72 and 73 arranged in opposite directions are adsorbed in a strong adsorbed state over a long time with respect to the adsorbed surfaces S1 and S2, respectively. Can be made.
Such an adsorber 71, for example, when storing tableware in a cupboard, if the first sucker 72 is adsorbed to the shelf of the cupboard and the bottom surface of the tableware is adsorbed to the second sucker 73, Tableware can be easily fixed and stored in the cupboard. Thereby, for example, when an earthquake occurs, it is possible to prevent the tableware from moving and sliding down or colliding with other tableware and cracking.
In addition, since the tableware can be further fixed on the upper surface of the tableware fixed using the suction tool 71, the tableware can be stacked and fixed.
Further, the suction tool 71 is composed of only four parts of two suction cups 72 and 73 and two pressing members 74 and 75, and the first pressing member 74 is attached to the shaft portion 76 of the first suction cup 73, Since the second pressing member 75 is attached to the shaft portion 77 of the second suction cup 73 and then the shaft portion 76 of the first suction cup 72 and the shaft portion 77 of the second suction cup 73 can be assembled, it can be assembled easily. As a result, the manufacturing cost can be reduced. Further, since the two suction cups 72 and 73 and the two pressing members 74 and 75 are both relatively simple structures, they can be manufactured at a relatively low cost, and the manufacturing cost can be reduced also in this respect.

FIG. 23 is a side view showing the configuration of the suction tool 91 according to the sixth embodiment of the present invention. FIG. 24 is a cross-sectional view showing the configuration of the suction tool 91. FIG. 25 is a schematic diagram showing a use state of the suction tool 91.

Since the 1st and 2nd suction cups 92 and 93 are the same structures as the suction cup 2 of 1st Embodiment, the same referential mark is attached | subjected and detailed description is abbreviate | omitted.
The pressing member 94 is configured by connecting a first pressing portion 95 and a second pressing portion 96 with a connecting portion 97.

The first pressing portion 95 has a substantially bowl shape and the same structure as the pressing member 3 of the first embodiment, and therefore the same reference numerals are used for the same configuration. The first pressing portion 95 is composed of the bottom plate 7 and the side plate 8. A fitting hole 7 a into which the shaft portion 5 of the first suction cup 92 is fitted is formed at the center of the disc-shaped bottom plate 7. On one side of the bottom plate 7, a first plate 95 having a substantially bowl shape is formed by forming the side plate 8. The side plate 8 is formed in a substantially cylindrical shape. More specifically, the side plate 8 has a diameter (as it goes away from the bottom plate 7, that is, from one end connected to the bottom plate 7 to the other end (opening side end) 8 a. The inner diameter is increased. An inner diameter D91 of the opening-side end portion 8a of the first pressing portion 95 is set smaller than the outer diameter of the first suction cup 92.
The opening-side end portion 8a is bent outward and has a so-called collar shape. That is, the opening-side end portion 8a is a portion formed in a substantially annular shape over the entire periphery of the side plate 8, and is a plate-like portion formed extending outward.
The diameter D92 of the fitting hole 7a of the bottom plate 7 is set to be smaller than the outer diameter D93 of the shaft portion 5 of the first suction cup 92, and from the outer diameter D94 of the cylindrical portion that becomes the bottom surface 5a1 of the fitting groove 5a. It is set large. Further, the thickness W91 of the bottom plate 7 is set smaller than the width W92 of the fitting groove 5a of the shaft portion 5 of the first suction cup 92.

Further, the first pressing portion 95 is formed with one notch 10 extending in a band shape toward the center of the bottom plate 7 from the opening-side end portion 8a to the fitting hole 7a of the bottom plate 7.
The second pressing portion 96 is also substantially bowl-shaped like the first pressing portion 95 and has the same structure as the pressing member 3 of the first embodiment, so the same reference numerals are used for the same configuration. . It consists of a bottom plate 7 and side plates 8. A fitting hole 7 a into which the shaft portion 5 of the second suction cup 93 is fitted is formed at the center of the disc-shaped bottom plate 7. By forming the side plate 8 on one side of the bottom plate 7, a substantially bowl-shaped second pressing portion 96 is formed. The side plate 8 is formed in a substantially cylindrical shape. More specifically, the side plate 8 has a diameter (as it goes away from the bottom plate 7, that is, from one end connected to the bottom plate 7 to the other end (opening side end) 8 a. The inner diameter is increased. An inner diameter D95 of the opening side end portion 25a of the second pressing portion 96 is set smaller than the outer diameter of the second suction cup 93.

The opening-side end portion 8a is bent outward and has a so-called collar shape. That is, the opening-side end portion 8a is a portion formed in a substantially annular shape over the entire periphery of the side plate 8, and is a plate-like portion formed extending outward.
The diameter D96 of the fitting hole 7a of the bottom plate 7 is set to be smaller than the outer diameter D97 of the shaft portion 5 of the second suction cup 93, and from the outer diameter D98 of the columnar portion that becomes the bottom surface 5a1 of the fitting groove 5a. It is set large. The thickness W93 of the bottom plate 7 is set to be smaller than the width W94 of the fitting groove 5a of the shaft portion 5 of the second suction cup 93.
Further, the second pressing portion 96 is formed with one notch 10 extending in a band shape toward the center of the bottom plate 7 from the opening side end portion 8a to the fitting hole 7a of the bottom plate 7.

The connecting portion 97 is formed in a substantially cylindrical shape, and the bottom plate 7 of the first pressing portion 95 is connected to one end portion, and the bottom plate 7 of the second pressing portion 96 is connected to the other end portion. The connecting portion 97 is formed with a notch 98 extending in a band shape from one end to the other end. The notch 98 has a notch 10 in the first pressing portion 95 and a notch in the second pressing portion 96. 10 communicate with each other. Therefore, the notch 10 of the first pressing part 95, the notch 98 of the connecting part 97, and the notch 10 of the second pressing part 96 are formed in a straight line.
The first pressing portion 95 can be easily deformed by forming the notch 10 in the same manner as the pressing member 3 of the first embodiment. That is, when the bottom plate 7 is pressed toward the opening end 8a against the first pressing portion 95 in the natural state, the notch 10 opens and the bottom plate 7 bends toward the opening end 8a, and the bottom plate 7 and the opening are opened. It will be in the deformation | transformation state which the side edge part 8a adjoined.
The fitting groove 5a of the shaft portion 5 is a back surface 4b when the suction surface 4a of the first suction cup 92 is attracted to the attracted surface S1 (precisely, the position where the opening side end portion 8a is in contact) ) To the side surface 5a2 facing the back surface 4b in the fitting groove 5a is a length L92 (see FIG. 25) from the opening-side end portion 8a to the bottom plate 7 in the natural state of the first pressing portion 95. It is formed at a position smaller than that shown in FIG. Therefore, when the 1st suction cup 92 is adsorb | sucking to the to-be-adsorbed surface S1, the 1st press part 95 attached to the axial part 5 of the 1st suction cup 92 will be maintained in a deformation | transformation state.

Moreover, the 2nd press part 96 becomes easily deformable similarly to the press member 3 of 1st Embodiment by forming the notch 10. FIG. That is, when the bottom plate 7 is pressed against the second pressing portion 96 toward the opening-side end portion 8a, the notch 10 opens and the bottom plate 7 bends toward the opening-side end portion 8a, thereby the bottom plate 7 and the opening-side end portion. 8a is brought into a deformed state.
The fitting groove 5a of the shaft portion 5 is a back surface 4b when the suction surface 4a of the second suction cup 93 is attracted to the attracted surface S2 (precisely, the position where the opening side end portion 8a is in contact). ) To the side surface 5a2 facing the back surface 4b in the fitting groove 5a (see FIG. 25) is longer than the length L94 from the opening side end 8a to the bottom plate 7 in the natural state of the second pressing portion 96. Is also formed at a position where it becomes smaller. Therefore, when the second suction cup 93 is attracted to the attracted surface S2, the second pressing portion 96 is maintained in a deformed state.

Next, with reference to FIG. 25, a procedure for sucking the suction tool 91 onto the suction target surfaces S1 and S2 will be described.
First, the first suction cup 92 is attached to the first pressing portion 95 of the pressing member 94. More specifically, since the diameter D92 of the fitting hole 7a of the bottom plate 7 is set smaller than the outer diameter D93 of the shaft portion 5 as described above, the shaft portion 5 formed of a soft material is compressed. Thus, when the bottom plate 7 is pushed into the fitting hole 7a of the bottom plate 7 of the first pressing portion 95 until the bottom plate 7 reaches the fitting groove 5a of the shaft portion 5, the compressed state of the shaft portion 5 is released. As described above, the width W92 of the fitting groove 5a is larger than the thickness W91 of the bottom plate 7, and the outer diameter D94 of the bottom surface portion 5a1 of the fitting groove 5a is smaller than the diameter D92 of the fitting hole 7a of the bottom plate 7. The first suction cup 92 is attached to the first pressing portion 95 with the bottom plate 7 fitted in the fitting groove 5 a of the portion 5. At this time, the first pressing portion 95 is in a natural state.

  Next, the second suction cup 93 is attached to the second pressing portion 96 of the pressing member 94. More specifically, since the diameter D96 of the fitting hole 7a of the bottom plate 7 is set smaller than the outer diameter D97 of the shaft portion 5 as described above, the shaft portion 5 formed of a soft material is compressed. Then, when the bottom plate 7 is pushed into the fitting hole 7a of the bottom plate 7 of the second pressing portion 95 until the bottom plate 7 reaches the fitting groove 5a of the shaft portion 5, the compressed state of the shaft portion 5 is released. As described above, the width W94 of the fitting groove 5a is larger than the thickness W93 of the bottom plate 7, and the outer diameter D98 of the bottom surface portion 5a1 of the fitting groove 5a is smaller than the diameter D96 of the fitting hole 7a of the bottom plate 7. With the bottom plate 7 fitted in the fitting groove 5 a of the part 5, the second suction cup 93 is attached to the second pressing part 96. At this time, the second pressing portion 96 is in a natural state.

  Next, the suction surface 4a of the first suction cup 92 is pressed against the suction target surface (for example, the upper surface of the shelf board) S1 of the first object. Here, the fitting groove 5a formed in the shaft portion 5 of the first suction cup 92 is a back surface 4b (when the suction surface 4a of the first suction cup 92 is attracted to the suction surface S1 of the first object. Exactly, the length L91 from the position where the opening side end 8a is in contact) to the side surface 5a2 facing the back surface 4b of the fitting groove 5a is the opening side end 8a in the natural state of the first pressing portion 95. To the bottom plate 7 is formed at a position smaller than the length L92. Therefore, a force is applied to the first pressing portion 95 so that the bottom plate 7 and the opening side end portion 8a are close to each other by the side surface 5a1 facing the back surface 4b of the fitting groove 5a and the back surface 4b of the suction cup body 4. Will be. As a result, the first pressing portion 95 is in a deformed state in which the notch 10 is opened and the bottom plate 7 is bent toward the opening side end portion 8a, and the bottom plate 7 and the opening side end portion 8a are close to each other.

The first pressing portion 95 in such a deformed state is such that the bottom plate 7 is fitted into the fitting groove 5 a of the shaft portion 5, and the opening side end portion 8 a is in contact with the peripheral portion of the back surface 4 b of the suction cup body 4. Will be attached to. At this time, the deformed first pressing portion 95 tends to be restored to the natural state by the elasticity of the material of the first pressing portion 95. Therefore, the opening side end portion 8a presses the peripheral edge portion of the back surface 4b of the suction cup body 4 toward the attracted surface S1 by the first pressing portion 95 trying to restore the deformed state to the natural state, and the bottom plate 7 A force is applied in a direction that separates the shaft portion 5 of the first suction cup 92 from the attracted surface S1.
In this way, the peripheral portion of the back surface 4b of the first suction cup 92 is pressed against the attracted surface S1, and the shaft portion 5 of the first sucker 92 is pulled away from the attracted surface S1, whereby the first sucker The space between the surface 92 and the attracted surface S1 is in a negative pressure state, and a strong adsorption state can be maintained for a long time.
Similarly, the suction surface 4a of the second suction cup 93 is pressed against the suction target surface (for example, the bottom surface inside the mug) S2 of the second object. As with the first suction cup 92, the second suction cup 93 can maintain a strong suction state for a long time.
In this way, the two objects can be fixed at a predetermined interval.

As described above, according to the sixth embodiment, the first and second suction cups 92 and 93 arranged in opposite directions are attracted to the attracted surfaces S1 and S2 in a strong adsorption state for a long time. Can be made.
Such an adsorbing tool 91, for example, when storing tableware in a cupboard, if the first suction cup 92 is adsorbed to the shelf of the cupboard and the bottom surface of the tableware is adsorbed to the second suction cup 93, Tableware can be easily fixed and stored in the cupboard. Thereby, for example, when an earthquake occurs, it is possible to prevent the tableware from moving and sliding down or colliding with other tableware and cracking.
Moreover, since the tableware can be further fixed using the suction tool 91 on the upper surface of the tableware fixed using the suction tool 91, a plurality of tableware can be stacked and fixed.
Further, the suction tool 91 is composed of only three parts, that is, two suction cups 92 and 93 and one pressing member 94. The first suction cup 92 is attached to the first pressing portion 95 of the pressing member 94, and the second pressing part 92 is pressed. Since it can assemble only by attaching the 2nd suction cup 93 to the part 96, it can assemble easily and it becomes possible to reduce manufacturing cost.
