FIELD OF THE INVENTION
The present invention relates to dual install suction mounting assemblies with interchangeable suction and adhesive pads.
BACKGROUND INFORMATION
Many bath accessories such as hooks, baskets, shower caddies, soap dishes and the like are currently held in place using suction cups. However, many bathroom walls do not offer a flat and smooth surface required for suction cups to adequately hold on the walls.
SUMMARY OF THE INVENTION
The present invention provides dual install suction mounting assemblies that include suction pads and adhesive pads that are interchangeably installed in the same housing. When the suction pad is installed, a handle is used to pull a suction disk from a flat position against a wall to a cupped position that holds the assembly tightly on the wall. When the adhesive pad is installed, a flat adhesive sheet secures the assembly to the wall.
An aspect of the present invention is to provide a suction mounting assembly comprising a housing, a handle adjacent to the housing comprising a central post, a suction pad comprising a suction disk engageable with the housing and a first support stem including a first central support post engageable with the central post of the handle, and an adhesive pad comprising an adhesive contact sheet engageable with the housing and a second support stem including a second central support post engageable with the central post of the handle, wherein the suction pad and adhesive pad are interchangeably mountable on the housing.
This and other aspects of the present invention will be more apparent from the following description.

DETAILED DESCRIPTION
The present invention provides consumers with a mounting assembly choice between using suction or a strong adhesive, utilizing the original suction cup casing. The consumer can selectively use a rubber type suction cup, or remove the rubber type suction cup and replace it with an adhesive pad that can be adhered to almost any surface.
FIGS. 1 and 2 illustrate a mounting assembly 10 including a housing 12 and a handle 30. A suction pad 40 is removably installed on the mounting assembly 10. In the configuration shown in FIGS. 1 and 2, the mounting assembly 10 may be secured to a bathroom wall or other smooth, flat surfaces by means of the suction pad 40.
FIGS. 3 and 4 illustrate an alternative configuration of a mounting assembly 110, which includes the same housing 12 and handle 30 of the configuration shown in FIGS. 1 and 2. The mounting assembly 110 includes a removably installed adhesive pad 60. In this configuration, the adhesive pad 60 may be used to secure the mounting assembly 110 on various types of bathroom walls and other surfaces that may not be smooth or flat enough for a suction pad to adequately hold the mounting assembly.
As shown in FIGS. 1-4, the same housing 12 and handle 30 are used for both the suction pad mounting assembly 10 and the adhesive pad mounting assembly 110. Accordingly, the same element numbers are used to describe the same structural features in both the configuration of FIGS. 1 and 2 and the configuration of FIGS. 3 and 4.
FIGS. 5-13 illustrate features of the suction pad mounting assembly 10 of FIGS. 1 and 2. The housing 12 includes a base flange 14, a conical sidewall 16 and a top wall 18. As described more fully below, the bottom surface of the base flange 14 includes concentric circular channels 15 that receive opposing concentric raised rings 45 of the suction pad 40. A central opening 19 is provided in the top wall 18 of the housing 12, as shown most clearly in FIGS. 9 and 10, as well as FIGS. 7 and 8.
The housing 12 includes a cylindrical central extension 20 having an outer cylindrical wall 21 and an inner cylindrical wall 22 forming a C-shaped channel 23 therebetween. A horizontal support channel 24 is provided in the cylindrical central extension 20 between the C-shaped channel and two support pillars 28. A vertical support channel 26 running between the support pillars intersects the horizontal support channel 24. The horizontal and vertical support channels 24 and 26 may be used to mount various types of bathroom accessories including hooks, shower caddies, soap dishes, and the like. The housing 12 may be made of any suitable material including plastics, metals and the like. For example, suitable plastics include polypropylene (PP), acrylonitrile butadiene styrene (ABS), high impact polystyrene (HIPS), nylon and the like.
As shown in FIGS. 5-8, the handle 30 is provided in the form of a knob including a front face 32 and sidewalls 34. The sidewalls 34 terminate in a contact edge 35 that engages the outer cylindrical wall 21 and the support pillars 28 of the cylindrical central extension 20. An interiorly threaded central post 36 is provided inside the handle 30. In the embodiment shown, the handle 30 has a generally square shape with rounded corners. However, any other suitable shape may be used. While the handle 30 may be provided as a rotatable knob, other embodiments of handles include levers, pull tabs and the like that can be manipulated by hand to pull a support stem 50 of the suction pad 40 inward into the housing 12 to form a suction cup, as more fully described below. The handle 30 may be made of any suitable material including plastics, metals and the like. For example, suitable plastics include PP, ABS, HIPS, nylon and the like.
As shown in FIGS. 7,8 and 11-13, the suction pad 40 includes an elastomeric suction disk 42 having a generally flat contact surface 43. The suction pad 40 includes an outer radial edge 44, a central body portion 46 and an interior face 47. As shown most clearly in FIG. 11, as well as FIGS. 7, 8, 12 and 13, the suction disk 42 includes concentric raised rings 45 on the surface opposite the contact surface 43. The concentric raised rings 45 are received within the concentric circular channels 15 of the housing 12 when the suction pad is installed on the housing 12. The suction disk 42 includes a central interior opening 48 extending through the interior face 47, as shown in FIGS. 7, 8 and 13. The suction disk 42 may be made of any suitable elastomeric material such as natural rubber, synthetic rubber, thermoplastic elastomers (TPE), thermoplastic polyurethane (TPU), thermoplastic rubber (TPR) and the like.
As shown in FIGS. 7,8 and 11-13, a support stem 50 is secured to the suction disk 42. The support stem 50 includes a disk-shaped support flange 52 having a radial outer edge 53 and circumferentially spaced through-holes 54. The support flange 52 may be the same or similar to the support flange 72 of the embodiment shown in FIGS. 16-18, as more fully described below. The support flange 52 is contained within the central body portion 46 of the suction disk 42, and extends through the interior opening 48 in the interior face 47. In the embodiment shown, an exteriorly threaded central support post 56 extends from the disk-shaped support flange 52. The support stem 50 may be made of any suitable material including plastics such as PP, HIPS, ABS, nylon and the like.
As shown in FIGS. 7 and 8, the exteriorly threaded central support post 56 of the support stem 50 extends through the central opening 19 of the housing 12 and is threaded onto the interiorly threaded central post 36 of the handle 30. Due to contact between the contact edge 35 of the handle 30 and the edge of the outer cylindrical wall 21 and support pillars 28 of the housing 12, rotation of the handle 30 causes extension and retraction of the threaded central support post 56 of the suction pad 40. As shown in FIG. 7, in the extended position, the entire contact surface 43 of the suction disk 42 is flat. As shown in FIG. 8, when the handle 30 is turned to draw the threaded central support post 56 into the threaded central post 36, the support stem 50 pulls the suction disk 42 inward to form a recessed suction cup 49. A portion of the suction disk 42 near the outer radial edge 44 maintains contact with a bathroom wall or other surface (not shown) as the recessed suction cup 49 is formed. As long as the periphery of the contact surface 43 of the suction disk 42 remains sealed against the mounting surface, a vacuum is maintained inside the recessed suction cup 49, which securely holds the suction pad mounting assembly 10 to the surface.
In the interchangeable adhesive pad configuration shown in FIGS. 14-18, the mounting assembly 110 includes the same housing 12 and handle 30 as the suction pad mounting assembly 10 described above. The adhesive pad 60 of the mounting assembly 110 includes an adhesive contact sheet 62 having an exterior contact surface 63, peripheral edge 64 and interior face 66. In the embodiment shown, the adhesive contact sheet 62 is generally square with rounded corners that extend beyond the radial outer edge of the base flange 14. This enables a user to grasp the corners when removing the mounting assembly 110 from a wall, as well as providing a larger adhesive surface area than the base flange. Alternatively, any other shape such as round may be used for the contact sheet 62. The adhesive contact sheet may have a typical thickness of from 0.1 to 7 mm, for example, from 0.5 to 3 mm.
The adhesive contact sheet 62 may be made of any suitable materials including plastics such as polyethylene (PE), PP, polyethylene terephthalate (PET) and the like. A layer of adhesive material may be applied on the contact surface 63 of the adhesive contact sheet 62. The adhesive material may be applied over the entire contact surface 63, or a portion thereof. Suitable adhesive materials include conventional pressure-sensitive adhesives and the like. Although not shown in the figures, a conventional release film may be applied over the adhesive contact surface 63 of the contact sheet 62 prior to installation of the mounting assembly 110 by a user.
As shown in FIGS. 16-18, the adhesive pad 60 includes a support stem 70 having a disk-shaped support flange 72 attached to the interior face 66 of the adhesive contact sheet 62. Any suitable means of attaching the support flange 72 to the adhesive contact sheet 62 may be used, including permanent adhesives, ultrasonic welding, mechanical fasteners, and the like. The support flange 72 has a radial outer edge 73 and circumferentially spaced through-holes 74. An exteriorly threaded central support post 76 extends from the disk-shaped support flange 72. As shown in FIG. 16, the threaded central support post 76 of the support stem 70 is threaded into the interiorly threaded central post 36 of the handle 30. As shown in FIGS. 16-18, movement-restricting bosses 78 extend from the support flange 72 and are spaced at equal 90 degree intervals around the circumference of the central support post 76. As shown in FIG. 16, the bosses 78 may be used to prevent retraction of the central support post 76 of the support stem 70 into the threaded central post 36 of the handle 30, which could otherwise occur in the absence of the bosses 78. In this manner, when a user installs the adhesive pad 60 in the mounting assembly 110, the adhesive contact sheet 62 and its contact surface 63 are maintained in a desired flat position, and any attempted rotation of the handle 30 by a user from the flat position shown in FIG. 16 does not result in inward movement of the central support post 76. Thus, when the adhesive pad 60 is threadingly installed on the housing 12 and handle 30, the bosses 78 act as stop members to maintain the adhesive contact sheet 62 and contact surface 63 in the flat position.
