<First Embodiment (FIGS. 1 to 7)>
First, a first embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the suction cup device 1 is for supporting a device A1 having a display function, such as a smartphone, on a fixed base A2 such as a table, a plurality of suction cups 2, 3 and these suction cups. And connecting means 4 for connecting two and three. More specifically, as shown in FIG. 2, the suction cup device 1 includes two suction cups 2 and 3 that can be attached to and detached from a device A1 and a fixed base A2 that are a plurality of suction targets A, and these suction cups. Connection means 4 for connecting the suction cups 2 and 3 to each other is provided so that the directions of the suction surfaces 21 and 31 can be relatively changed and held. In the present embodiment, the suction cup device 1 is configured such that the first suction cup 2 rotates three-dimensionally with respect to the second suction cup 3, as shown in FIG.

  As shown in FIGS. 1 to 4, each of the suction cups 2 and 3 is a normal one having a disk shape made of, for example, hard rubber or hard synthetic resin. Each of the suction cups 2 and 3 includes an inner surface that is used as the suction surfaces 21 and 31 that are attracted to the suction target A having a smooth surface, and outer surfaces 22 and 32 that are formed on the opposite side of the inner surface. ing. The inner surface forms a curved surface that is recessed toward the center. The outer side surfaces 22 and 32 form a curved surface protruding toward the center, and a mounting portion 23 (the mounting portion of the suction cup 3 is not shown) protrudes outward at the center portion. Further, on the outer side surfaces 22 and 32, there are projecting operation pieces (not shown) for removal used when removing the suction cups 2 and 3 from the suction target A.

  As shown in FIGS. 1 to 4, the connecting means 4 is configured by a plastic deformation member 43 that deforms when receiving an external force and self-holds the deformed posture when the external force is removed. The connection means 4 is mainly configured by twisting a plurality of wires 431. More specifically, the connecting means 4 includes a first base member 41 fixed to the first suction cup 2, a second base member 42 fixed to the second suction cup 3, and these base members. Three wires 431 mounted between 41 and 42 and a cover 44 covering these wires 431 from the outside are provided.

  The first base member 41 has, for example, a wooden cylindrical shape, and has a screw hole (not shown) formed in a circular one end 45, and a screw 47 inserted from the suction surface 21 side of the suction cup 2 is inserted. The suction cup 2 is fixed to the outside of the mounting portion 23. On the other end 46 side of the first base member 41, there are a through hole 461 for passing the wire 431 and a guide groove 462 extending in the longitudinal direction of the first base member 41, which is continuous with the through hole 461. Is provided. The second base member 42 conforms to the first base member 41, and portions corresponding to the first base member 41 are denoted by the same reference numerals and detailed description thereof is omitted.

  The wire 431 is made of metal that deforms when receiving an external force and self-holds the deformed posture when the external force is removed so that the first suction cup 2 and the second suction cup 3 are back to back. To connect to. The wires 431 are mounted in the through holes 461 and the guide grooves 462 of the first base member 41 and the second base member 42, respectively, and the other end portions 46 of the first base member 41 and the second base member 42. , 46 are twisted.

  The cover 44 is made of, for example, deformable synthetic resin, and covers the twisted portion of the wire 431 from the outside so that the other ends of the first base member 41 and the second base member 42 are covered. Arranged between the portions 46 and 46.

  Furthermore, the connection means 4 of this embodiment is provided with a suction reinforcement member 7 that is disposed on the opposite side of the suction surfaces 21 and 31 of the suction cups 2 and 3 and reinforces the suction state of the suction cups 2 and 3. Each adsorption reinforcement member 7 is a thin plate having a substantially annular shape in plan view, and is attached along the outer surfaces 22 and 32 of the suction cups 2 and 3 by punching and deforming a sheet metal material, for example. More specifically, each adsorption reinforcing member 7 includes a pressing portion 70 that presses the suction cups 2 and 3 in the thickness direction, and is formed over the outer edge 71 and the inner edge 72 in one annular position. A notch 73 is provided. As the suction cups 2 and 3 are deformed, the overlapping states of the edges 74 and 75 of the notch 73 are changed so that the respective suction reinforcing members 7 are in close contact with the outer surfaces 22 and 32. And the inner edge 72 of the adsorption | suction reinforcement member 7 is pressed by the one end part 45 of the said base members 41 and 42 in the thickness direction. The adsorption reinforcing member 7 is shown with a pattern in the drawing.

  When the suction cup device 1 configured as described above is used as a smartphone support device, the suction surfaces 21 and 31 of the suction cups 2 and 3 are directed toward the suction surface of the suction target A as shown in FIG. By pressing the center portions of the outer surfaces 22 and 32 of the suction cups 2 and 3 in the direction of the suction surface, the suction surfaces 21 and 31 and the suction surface are almost in a vacuum state. It can be adsorbed and fixed on the adsorption surface. More specifically, the first suction cup 2 is attached to the upper surface of the fixed base A2 that is the first suction target A, and the second suction cup 3 is attached to the back surface of the device A1 that is the second suction target A. . Then, before or after attaching the suction cups 2 and 3 to the suction target A, an external force is applied to the connecting means 4 to plastically deform the wire 431, and the directions of the suction surfaces 21 and 31 of these suction cups 2 and 3 Is changed relatively. If the external force is no longer applied to the connecting means 4 after changing the angle of the other suction surface 31 with respect to the one suction surface 21, the angle is held by the self-holding force of the plastic deformation member 43, and the upper surface of the fixing base A2 The display screen of the device A1 can be set to a desired angle.

  Thus, the suction cup device 1 of the present embodiment is connected so that the suction cups 2 and 3 making a pair and the suction surfaces 21 and 31 of the suction cups 2 and 3 can be relatively changed and held. Therefore, the relative angle between the suction surfaces 21 and 31 can be changed to a desired direction, and the degree of freedom of use can be increased. That is, since the plurality of suction cups 2 and 3 can be mounted so as to be aligned on a single plane as in the prior art, they can be mounted on two suction surfaces having various angles. It can also be used for other purposes. Moreover, according to the suction cup device 1 of the present embodiment, the suction face of the suction target A has a flat surface that can suck the suction cups 2 and 3 in accordance with the purpose of use without fouling or damaging the suction face. You can connect each other. Even if the object to be attracted cannot be attracted, if the surface to be attracted is formed by using an attachment auxiliary tool such as an acrylic plate, the object to be attracted will spread infinitely.

  Furthermore, since the suction cup device 1 of the present embodiment is configured such that the first suction cup 2 rotates three-dimensionally with respect to the second suction cup 3, the first and second suction cups. The two and three suction surfaces 21 and 31 can be directed in a desired direction, and the degree of freedom of use can be increased. Therefore, the apparatus A1 attached to the second suction cup 3 can be moved in a desired direction while the first suction cup 2 is supported by the fixed base A2.

  The connecting means 4 is composed of a plastic deformation member 43 that deforms when receiving an external force and self-holds the deformed posture when the external force is removed. After turning in the direction, the shape can be held for a certain time until an external force is applied again to the plastic deformation member 43. In particular, in the present embodiment, since the connecting means 4 is obtained by twisting three wires 431, the above-described aspect can be easily realized.

  Further, since the connecting means 4 is deformable, and the connecting means 4 is deformed, the distance between the first suction cup 2 and the second suction cup 3 can be changed. Not only the relative angles of the suction surfaces 21 and 31 of the first and second suction cups 2 and 3 but also the relative positions can be changed, and the degree of freedom of use can be further increased. Specifically, for example, as shown in FIG. 5, the distance between the first suction cup 2 and the second suction cup 3 can be shortened by bending the connecting means 4. In addition, the thing of this FIG. 5 is a thing longer than the connection means 4 shown in FIGS. 1-3.

  Further, the connecting means 4 can be used as a hanger for hanging a relatively light weight, for example.

  As an example of the other use of the suction cup device 1 of this embodiment, the case where the suction cup device 1 is used as a support device of the smartphone A4 as shown in FIG. In this case, the first suction cup 2 is attached to the inner surface of the windshield A3 of the car that is the first suction target A, and the second suction cup 3 is attached to the back surface of the smartphone A4 that is the second suction target A. What should I do? In addition, the 1st to-be-adsorbed object A may be the surface of the instrument panel of a vehicle, the surface of a vehicle rearview mirror, the upper surface of a dashboard, etc. Further, the second suction target A may be an electronic device equipped with a car navigation system, a portable audio device, or the like.

  As another example of the application, for example, as shown in FIG. 7, the suction cup device 1 is used as a mounting device for the auxiliary headlight A6. In this case, the first suction cup 2 is attached to the outer surface of the helmet A5 that is the first suction target A, and the second suction cup 3 is attached to the side surface of the light A6 that is the second suction target A. That's fine.

  In addition, although the 1st suction cup and the 2nd suction cup in the suction cup apparatus of this embodiment were shown so that a shape and a size might mutually differ, the 1st suction cup and the 2nd suction cup are the same thing Of course it may be.

  Further, the plastic deformation member of the connecting means may be obtained by twisting two or more wires in addition to the three wires twisted. Furthermore, a stranded wire formed by combining a plurality of wires can have excellent flexibility and resistance to bending and twisting.

  As long as the connecting means can shorten the distance between the first suction cup and the second suction cup by bending in a loop shape as shown in FIG. 5, for example, one wire or a plurality of wires are used. Regardless of whether the plurality of wires are twisted or not, any wire may be used.

  Further, the first base member and the second base member are not limited to those described above with respect to the shape, size, material, and the like, and may be anything. For example, the first base member and the second base member can be made of various materials such as metal, synthetic resin, and the like in addition to wood.

  The first base member or the second base member may not be provided with a guide groove. For example, when a twisted three or more wires are used as the connecting means, the wires are firmly attached to the first or second base member without the need to use guide grooves when twisted. It will be. On the other hand, in the case of using a twisted two wire as the connecting means, it is preferable that there is a guide groove in order to improve the wire mounting state on the first or second base member. In this way, the wire can be fixed to the first or second base member without using an adhesive by a combination of twisting of the wire and the guide groove, or only by twisting of the wire.

  As an example of the first base member and the second base member made of synthetic resin, it is conceivable to use a pipe capable of accommodating a plurality of wires inside. That is, the connecting means includes a first base member fixed to the first suction cup, a second base member fixed to the second suction cup, and a plurality of pieces mounted between the base members. And a wire. More specifically, the first base member is a short pipe-shaped member made of, for example, flexible synthetic resin, and one end portion is attached to the attachment portion of the first suction cup from the outside. It is fixed to the mounting portion of the first suction cup by using a screw inserted from the outside of the through hole provided in the portion. The other end side of the first base member is open, and one end of a plurality of wires is accommodated therein. The end of the wire is fixed to the first base member using an adhesive or the like injected into the pipe. The second base member may be based on the first base member. When the first base member and the second base member are made of metal, after inserting the wire, the notch provided in the first base member and the end of the wire are caulked. Thus, the wire can be fixed to the first base member.

  Further, the first and second base members are not limited to those of the above-described embodiment, and can be variously changed. For example, you may make it attach a connection means directly to the synthetic resin attachment part located in the other side of the adsorption | suction surface of the said suction cup without passing through the 1st, 2nd base member. In this case, it is preferable to attach the connection means at a position as close as possible to the attachment portion of the suction cup. That is, the operation of relatively changing the direction of the suction surface of the suction cup with respect to the connection means as the connection location between the suction cup and the connection means becomes farther from the tip side of the mounting portion, i.e., the outer surface of the suction cup. When this is done, the attachment part that is relatively easily deformed by the external force is also deformed together. Therefore, it becomes difficult to set the suction surface of the suction cup in a desired direction. However, if the connecting means is attached in the vicinity of the outer surface of the attachment part of the suction cup, the deformation of the attachment part due to the external force can be suppressed, and the above-described problems can be eliminated or suppressed. Note that, as in the first embodiment described above, the first and second base members having relatively rigidity are attached to the attachment portion, and the suction cup and the connecting means are connected via the first and second base members. As long as the connection portion between the suction cup and the connection means is provided on the distal end side of the mounting portion, the above-described problems cannot occur.

  Further, as the suction cup device, it is desirable to connect with the connection means in the vicinity of the outer side of the attachment part of the suction cup and to arrange the suction reinforcement member on the outer side of the suction cup. The suction cup can be firmly fixed at a desired position with a minimum operating force.

  The method of fixing the first or second base member to the first or second suction cup is not limited to the above-described method of fixing with the screw, and can be variously changed. Further, when fixing with a screw, if it is fixed via a washer, connection can be made without using an adhesive, and air leakage can also be suppressed. Various materials such as those made of synthetic resin or metal can be used as the material of the washer at this time. As a specific example, a washer (not shown) having a diameter smaller than that of the suction surface 21 may be attached to the suction surface 21 side of the suction cup 2. More specifically, this washer is a metal plate-like member that is sandwiched when the screw 47 is screwed into the screw hole, and increases the fixing force of the screw 47 with respect to the suction cup 2 so that the connecting means 4 On the other hand, it is possible to suppress a problem that the screw 47 is detached from the suction cup 2 due to an external force applied when the direction of the suction surface 21 of the suction cup 2 is relatively changed. In this way, if the washer is disposed on the inner surface side of the suction cup and the suction reinforcement member functioning as a washer is disposed on the outer surface side of the suction cup, the suction cup is sandwiched from both sides and sucked to the suction target. The shape can be stably maintained.

  The adsorption reinforcing member is not limited to the above-described shape and material and can be variously changed. For example, the cutout portion may be any shape as long as it can be deformed with the deformation of the suction cup, for example, it is formed so that the outer edge and the inner edge are not continuous. May be. Moreover, as another example of a notch part, you may form in the planar view spiral shape. Specifically, an elastically deformable wire spirally wound can be used as the adsorption reinforcing member, and in this case, a spiral notch is formed between adjacent wires. It becomes.

  Furthermore, the adsorption reinforcing member may not have a notch. That is, when a relatively small suction cup is used, the suction reinforcement member attached to the suction cup is also relatively small. In this case, even if an adsorption reinforcing member not provided with a notch is used, the suction state of the suction cup can be reinforced in a manner similar to that having the notch. In addition, even when a relatively large suction cup is used, it is preferable that the suction reinforcement member be deformed and pressed toward the suction surface along the outer surface of the suction cup. You may make it press gently to the adsorption | suction surface side using a washer.

  Also for the material of the adsorption reinforcing member, various soft metals such as copper and aluminum, which are easily deformed, and synthetic resins can be applied.

  Further, the use application of the suction cup device is not limited to the above-described one, and various changes can be made.

It is fixed to the outside of the suction cup 2 using The other end 46 of the first base member 41 is provided with a female screw hole 463 extending in the thickness direction of the suction cup 2. The second base member 42 conforms to the first base member 41, and portions corresponding to the first base member 41 are denoted by the same reference numerals and detailed description thereof is omitted.

Since it is made to couple | bond by screwing, a coupling | bond part does not appear on an outer surface but it can make an aesthetics favorable. In addition, the distance between the first suction cup 2 and the second suction cup 3 can be changed by changing the degree of attachment of the male screw portion 432 to the female screw hole 463. Further, in the present embodiment, since the first and second base members 42 are made of wooden material that is a relatively hard material, the female screw hole 463 can be easily formed.

The joint 52 is formed by the plurality of wires 524.

  The first base member 521 has, for example, a wooden cylindrical shape, and is formed with a screw hole (not shown) in one end portion 525 having a circular shape, and a screw (not shown) inserted from the suction surface 21 side of the suction cup 2.
