March 9, 1965 1-. E. MAUSHUND SUBMERGED SURFACE CLEANING APPARATUS Filed July 19, 1962 INVENTOR THOMAS E. MAUSHUND United States Patent O 3,172,415 SUBMERGED SURFACE QLEANING APPARATUS Thomas E. Mauslnmd, 1.5731 E. El Soneto Drive, Whittier, Qalif. Filed Italy 19, 19 62, Ser. No. 211,019 6 Claims. (ill. 134--93) This invention relates generally to an underwater cleaning apparatus, and more particularly to a device for retaining a cleaning solution directly in contact with a submerged surface of a fluid container such as a swimming pool which has algae, calcium deposits or stains so that they may be removed without draining the pool.
It is common practice in cleaning a swimming pool which has collected algae and calcium deposits on the walls and bottom, to first drain it and then wash and flush it down with a muriatic acid solution, or to place a small cloth bag of calcium hypochloride over the algae spots for a period of 24 hours.
Briefly and in general terms the present invention provides a bell which integrally embodies means for supporting a capsule containing an appropriate cleaning substance. When punctured before submergence, the capsule will provide a strong cleaning solution inside the bell, which is placed directly over the spot or stain to be removed.
The bell is pressed to the wall or floor by removable handle means and is held by suction until removed, thus keeping the strong cleaning solution confined and in direct contact with the algae spot or stain. Following installation of the bell over the site to be cleaned, the handle can be removed, to allow the pool to be used.
Accordingly, it is an object of the present invention to provide a new and improved means for removing algae spots, calcium deposits, and stains from the submerged floor and wall surfaces of a fluid container, without draining the same.
It is another object to provide a new and improved means for cleaning submerged surfaces of a swimming pool without preventing use of the pool during the cleaning operation.
These and other objects and features of the present invention will become more apparent from the following description thereof, reference being made to the figures of the accompanying drawing, wherein:
FIGURE 1 is a partial plan view illustrating a presently preferred form of the acid cleaning apparatus embodying the present invention;
FIGURE 2 is a vertical sectional view through the acid cleaning apparatus illustrated in FIGURE 1, following its installation and removal of the handle; FIGURE 3 is a fragmentary elevation view looking toward the adapter which connects the cleaning apparatus to a lightweight pole; FIGURE 4 is a bottom plan view looking upward into the cleaning apparatus of FIGURES 1 and 2; and FIGURE 5 is a fragmentary view of the pivot neck connection, and the pivot neck extension portion of the invention showing means for securing the lightweight pole to the cleaning apparatus.
Referring now in detail to FIGURES 1 through 5, the cleaning apparatus comprises a molded cup of rubber or like flexible material indicated generally at 1. The cup 1 is substantially circular in shape and provides a pivot neck connection 7 to which an adapter 8 is removably secured. A lightweight pole 9 is secured to the adapter 8 which, in turn, is inserted in a slotted pivot neck extension 10 and revolved a quarter turn, and is held in place by a spring 11; this allows the pole 9 to be removed from 3,172,4l5 Patented Mar. 9, 1965 the pivot neck extension 10 after the cleaning apparatus is placed in contact with a spot or stain 3, which is to be removed from a submerged surface 2.
The cup 1 has a cavity e molded or otherwise integrally embodied by its inner face and providing a plurality of fingers 4 to hold a gelatinous capsule 5 containing an acid or other appropriate cleaning substance in place until the cup 1 has been installed over the spot or stain 3.
The construction thus provided is easy to produce and use, whereas it serves to effect the thorough cleaning of algae spots, calcium deposits and stains from swimming pools while filled with water.
The cup 1 may, of course, be oval in form or have other suitable shapes. In view thereof, it should be understood that the particular embodiment of the invention shown in the drawing and described above is intended to be illustrative only and is not intended to limit the scope of the invention.
1. In a cleaning apparatus, the combination comprising: flexible cup means defining a suction chamber; and flexible means integrally formed with said cup means for supporting within said suction chamber a container of a cleaning substance.
2. Apparatus for cleaning submerged surfaces in a fluid container, comprising: flexible cup means having inner and outer faces; and flexible finger means integral with and extending from said inner face for grasping and supporting a container of a cleaning substance.
3. Cleaning apparatus, comprising: a flexible cup having an inner face and a cavity within said inner face; and flexible finger means integral with said cup and surrounding said cavity for grasping a container of a cleaning substance extending into said cavity.
4. A device for cleaning submerged surfaces, comprising: a flexible cup having an inner face defining a suction chamber, said inner face having a centrally disposed cavity therein; and flexible finger means integrally formed with said cup and surrounding said cavity for grasping a capsule of a cleaning substance extending into said cavity.
5. In a cleaning apparatus, the combination comprising: flexible cup means; flexible means integrally formed with said cup means for supporting from the inner face thereof a container of a cleaning substance; and detachable handle means coupled to said cup means.
6. A cleaning apparatus, comprising: flexible cup means having inner and outer faces; flexible finger means integral with and extending from said inner face for grasping a container of a cleaning substance; a pivotal coupling extending from said outer face of said flexible cup means; and elongated handle means for detachably engaging said pivotal coupling.
