Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a suction cup attachment (hereinafter, simply referred to as attachment). More specifically, the present invention relates to a fixture that is suitable for use in bathrooms and kitchens, has a simple structure, and has durability.

[0002]

[Prior Art]

 Conventionally, after the suction cup is pressed against the wall surface for adsorption, the center of the back surface of the suction cup is pulled in the direction of the back surface, and the reaction force presses the suction cup near the peripheral edge against the wall surface over the entire circumference, and at the same time, it is placed inside the suction cup. There is known a fixture that increases a suction force by creating a negative pressure space.

An example of such a fixture is shown in FIG.

This is composed of a suction cup 51, a connecting shaft 52 projecting from the center of the back surface thereof, and a bottomed cylindrical pressing member 53 screwed to the connecting shaft 52. A male screw 54 is provided at the tip of the connecting shaft 52, and a female screw 55 that engages with the male screw 54 is provided at the center of the bottom of the pressing member 53.

The fixture constructed as described above is used as follows.

After the suction cup 51 is adsorbed on the wall surface W, the pressing member 53 is screwed into the connecting rod 52 of the suction cup 51 so that the pressing member 53 presses the vicinity of the peripheral edge of the suction cup 51 against the wall surface W and pulls the connecting shaft 52. A negative pressure space 56 is created inside the suction cup 51 to increase the suction force.

Next, another example of the conventional fixture is shown in FIG. This is composed of a connecting shaft 62 projecting from the center of the back surface of the suction cup 61, a cylindrical pressing member 63 with a bottom fitted loosely into the connecting shaft 62, and a swingable movement at the tip of the connecting shaft 62. The cam rod 64 is pivotally supported. A cam surface 65 that abuts the back surface of the pressing member 63 is formed at the tip end of the cam rod 64 on the suction cup 61 side.

In this mounting tool, the cam rod 64 is set at the position shown by the chain double-dashed line in FIG. 8, the cam surface 65 is not brought into contact with the back surface of the pressing member 63, and the suction cup 61 is attached to the wall surface W. Adsorb. Then, the cam rod 64 is rotated in the direction of arrow A in FIG. 8 to bring the cam surface 65 into contact with the back surface of the pressing member 63. By doing so, the cam bar 64 presses the suction cup 61 side end edge of the pressing member 63 against the wall surface W via the vicinity of the peripheral edge of the suction cup 61, and also creates a negative pressure space inside the suction cup 61. And the same effect as the fixture of FIG. 7 is exhibited.

[0009]

[Problems to be solved by the device]

 However, in the fixture shown in FIG. 7, it is troublesome to tighten the screw to pull the suction cup 51. In addition, manufacturing costs increase because threading is required. Furthermore, it is made of metal so as to withstand the pulling force of the suction cup 51 and the pulling force applied when using the suction cup 51 (for example, when an object is hung on the hook connected to the pressing member 53). Or it is common to use engineering plastic screws such as polycarbonate. In this case, since the male screw 54 is insert-molded on the suction cup 51 and the female screw 55 is insert-molded on the pressing member, there are problems such as an increase in manufacturing cost. When the pressing member 53 is screwed in, the back surface of the suction cup 51 may be rubbed against the pressing member 53 and damaged. In order to prevent this damage, the pressing member 53 is separated from the cylindrical part (53a in Fig. 7) and the application part (53b in Fig. 7) where the hook on the back side is provided, and the female screw is used only in the application part 53b. However, in that case, the number of parts will increase and the manufacturing cost will increase, and the storage and management before use will be troublesome.

On the other hand, in the fixture shown in FIG. 8, in order to secure the strength of the shaft support portion, it is necessary to enlarge the portion or make it into a metal, which causes an increase in manufacturing cost. Further, since the cam surface 65 and the back surface of the pressing member 63 are strongly rubbed against each other and are likely to be worn, the effect of increasing the suction force is reduced if used frequently. Since the number of parts is large and the assembly process is also required, the manufacturing cost rises. Furthermore, the cam bar in use (shown by the solid line in FIG. 8) has a problem that it is difficult to handle because the cam disengages with light force and rotates upward (shown by the two-dot chain line in FIG. 8). There is.

The present invention has been made in order to solve the above problems, and an object thereof is to provide a fixture which is easy to manufacture because it has a small number of parts and a simple structure, and which is not easily broken. To do.

[0012]

[Means for Solving the Problems]

 The suction cup mount of the present invention has a suction cup having a neck and a head having a diameter larger than the neck protruding from the center of the back surface, and a mounting hole for engaging the coupling shaft.

Has a space that can be fitted and inserted into the space, and the slope is formed on at least one of the fitting and inserting edge of the connecting plate into the space and the mounting body that defines the space, It is also preferable that the slope is configured so that the connecting plate moves in a direction away from the wall surface as the connecting plate is inserted into the space.

[0015]

[Action]

 After sucking the suction cup at a desired position on the wall surface, the head portion of the connecting shaft of the suction cup is inserted into the communication hole provided in the mounting means. The attachment means is moved so that the neck portion of the connecting shaft is laterally passed along the elongated hole of the cam portion. At that time, since the abutting part of the mounting means is in contact with the wall surface, the head of the suction cup is lifted by the slope of the cam part, and as a result, the suction cup is pulled rearward in the vicinity of its center through the connecting shaft. Be done. Then, a negative pressure space is created inside the suction cup, and the suction force increases.

The attachment of the present invention has a simple structure in both its suction cup and attachment means, and does not require any special processing or assembly process. In addition, when used, it can be engaged and disengaged from the suction cup by simply moving the mounting means slightly, so handling is extremely easy.

 Next, the fixture of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a partially cutaway perspective view showing an embodiment of the attachment of the present invention, FIG. 2 is a sectional view showing the attachment of FIG. 1 after attachment, and FIG. 3 is another view of the attachment of the present invention. 4 is a cross-sectional view showing an embodiment of the present invention, FIG. 4 is a perspective view before assembly showing still another embodiment of the fixture of the present invention, and FIGS. 5 to 6 are cross-sectional views illustrating a method of using the fixture of FIG.

In FIG. 1, reference numeral 1 is a fixture, which is composed of a suction cup 2 and a pressing member 3. In the case of the present embodiment, the pressing member 3 corresponds to the "mounting means" referred to in the claims of utility model registration. A connecting shaft 4 is projectingly provided at the center of the back surface of the suction cup 2, a neck portion 5 having a slightly smaller diameter is formed in a middle portion of the connecting shaft 4, and the neck portion 5 is followed by a neck portion having a diameter smaller than that of the neck portion 5. A large head 6 is formed.

On the other hand, the pressing member 3 is composed of a pressing cylinder 7 having a substantially bottomed cylindrical shape, and a hook portion 8 formed integrally with the bottom rear surface of the pressing cylinder 7. The edge 10 on the opening 9 side of the pressing cylinder 7 is a portion that presses the vicinity of the peripheral edge of the suction cup 2 over the entire circumference. The hook portion 8 is used for various purposes after the mechanism is fixed to the wall surface W or the like.

A long hole 11 having a width wider than the diameter of the neck portion and narrower than the diameter of the head portion 6 is formed in the bottom portion of the pressing portion 7 so that the neck portion 5 of the connecting shaft 4 can be moved. There is. A communication hole 12 having a larger opening than the head 6 is formed at one end of the long hole 11. The long hole 11 and the communication hole 12 constitute a mounting hole 13 for mounting the pressing member 3 on the suction cup 2.

The bottom of the pressing cylinder 7 constitutes a cam plate 14, and the plate thickness on both sides of the long hole 11 is from the continuous portion of the communication hole 12 and the long hole 11 to about half of the long hole 11 in the longitudinal direction. It gradually becomes thicker over time. That is, the back surface of that portion is a slope (hereinafter referred to as a cam surface) 15.

Next, how to use the fixture 1 configured as described above will be described.

First, the suction cup 2 is pressed to a desired position on the wall surface W to be adsorbed. Next, the pressing member 3 is set on the suction cup 2 so that the head 6 of the connecting shaft 4 is inserted into the communication hole 12. At this time, the end edge 10 of the pressing cylinder 7 abuts on the entire periphery of the suction cup 2 near the peripheral edge thereof. Subsequently, the pressing member 3 is moved so that the neck portion 5 of the connecting shaft 4 follows the elongated hole 11. In this case, the load generated when using the hook portion 8 integrally connected to the suction cup 2 is often applied downward (for example, when an object is hung on the hook portion 8). It is preferable to engage the suction cup 2 by moving it from the top to the bottom in order to prevent disengagement. Then, the head 6 slides on both sides of the long hole 11 (on the cam surface 15) in an engaged state, so that the suction cup 2 is pulled by the cam surface 15 in the direction of coming off via the connecting shaft 4 (see FIG. 2). ). At the same time, the suction cup 2 is pressed against the wall surface W by the end edge 10 of the pressing cylinder 7, and a negative pressure space 16 is further generated inside, so that the suction force is increased.

In this embodiment, the hook portion 8 is integrally formed with the pressing cylinder 7, but the present invention is not limited to the hook, and the pressing cylinder 7 and the pressing cylinder 7 having a shape according to the application can be used. The pressing member may be a combination of the above, and for example, as shown in FIG. 3, a pressing member 19 formed by integrally forming a locking piece 18 for locking to the support 17 with the pressing cylinder 7. In this case, the support column 17 is composed of a pair of elastic rod members 20a, 20b which are separated from each other and fixed in parallel. The locking piece 18 has a locking portion composed of a pair of hooks 21a and 21b facing each other. In the pressing member 19 configured as described above, when one of the hooks 21a is locked to the one rod member 20a and then pressed against the column 17, the tip of the other hook 21b pushes the other rod member 20b. It will be. As a result, the two rod members 20a, 20b bend in a direction in which they approach each other, so that they are easily engaged between the snap and the two hook portions 21a, 21b. Since the pressing member 19 can slide on the column 17 in the above-mentioned engaged state, the suction position of the suction cup on the wall surface W can be easily changed. When removing the pressing member 19 from the column 17, pull the one hook 21a away from the bar member 20a locked to it so that the tip of the hook 21a pushes the bar member 20a. The members 20a, 20b flex so as to approach each other and are easily disengaged from the snap.

It is convenient to combine the above-mentioned pressing member 19 and the support 17 so that shelves can be freely constructed on the wall surface W.

In the embodiment, the pressing member has a cylindrical shape, but the present invention is not limited to a cylindrical shape, and may be, for example, a polygonal cylinder such as a hexagon or an elliptic cylinder. .. However, the cylindrical shape is preferable because the suction cup can be pressed uniformly against the wall surface W over the entire circumference.

FIG. 4 shows a fixture 22 having a plurality of suction cups 2. That is, it has one connecting plate 23 for attaching two suction cups 2. The connecting plate 23 is a substantially rectangular plate, and has two mounting holes 24 having the same shape as the mounting hole 13 in FIG. Then, a slope 26 is formed in the vicinity of the upper edge 25 of the side of the connecting plate 23 to which the suction cup 2 is attached, that is, the side corresponding to the wall surface W, and the upper edge 25 has a so-called knife edge shape.

Reference numeral 27 denotes a mounting body, which is a member covered by the connecting plate 23. That is, in this embodiment, the tray 28 for placing the soap is integrally formed, and the one side wall 29 thereof has the compartment 30 into which the connecting plate 23 is fitted. As shown in FIGS. 5 to 6, the compartment 30 has a substantially U-shaped cross section whose upper end is closed by the side wall 29 and an engaging portion 31 projecting from the side wall 29 and having a substantially L-shaped cross section. It is formed to have a V-shaped cross section. An abutting portion 32 that abuts the wall surface W is formed on the outer surface of the engaging portion 31 on the wall surface W side. Inside the compartment 30, an inclined portion 33 is formed on the inner surface of the engagement portion 31 (see FIGS. 5 to 6). The inclined portion 33 is configured to be moved in a direction in which the plate-shaped member is separated from the wall surface W (rightward in FIGS. 5 to 6) as the plate-shaped member is inserted, for example.

The connecting plate 23 and the mounting body 27 described above constitute the mounting means referred to in the scope of claims for utility model registration.

A method of using the fixture 22 of this embodiment will be described with reference to FIGS.

First, the two suction cups 2 are locked in the mounting holes 24 of the connecting plate 23, respectively. After that, the suction cup 2 is pressed to a desired position on the wall surface W to be adsorbed (see FIG. 5). Then, the mounting body 27 is provided on the connecting plate 23 so that the connecting plate 23 is fitted into the compartment 30. At this time, since the abutting portion 32 of the mounting body 27 is in contact with the wall surface W, as the mounting body 27 is fitted into the connecting plate 23, the slope 26 and the inclined portion 33 act on the connecting plate 23. Is applied to the wall surface W to separate it from the wall surface W. As a result, a negative pressure space 16 is generated inside the suction cup 2 and the suction force increases (see FIG. 6).

As described above, in the fixture 22 using the connecting plate 23, a large container or shelf which requires a plurality of suction cups 2 can be easily and strongly operated without the need to perform suction positioning of the suction cups 2. It can be firmly attached to the wall surface W.

In this embodiment (see FIGS. 4 to 6), the connecting plate 23 and the mounting body 27 are provided with the slope 26 and the inclined portion 33. However, in the present invention, only one of them is provided. May be provided. In short, by covering the attachment plate 27 on the connecting plate 23, a force in a direction away from the wall surface W is applied to the connecting plate 23, and as a result, the negative pressure space 16 is generated inside the suction cup 2.

The material of the suction cup in the fitting of the present invention is not particularly limited as long as it is a general suction cup material having flexibility, appropriate elasticity and strength, and, for example, synthetic resin or synthetic rubber is used. There is. On the other hand, the material for the pressing member, the connecting plate and the mounting body is not limited as long as it has high strength, appropriate elasticity and good workability and moldability. For example, metal or synthetic resin is used. However, a synthetic resin is preferable because it is lightweight and can be integrally formed with a target object such as a hook or a locking piece.
