Description

Vacuum Cleaner Carrying Apparatus

The present invention relates to a carrying apparatus, which allows the user to carry the dust-bagged and dust-bagless electric vacuum cleaners having dry suction characteristics, which is used by pulling and pushing on the floor, on his/her back. In this document unless otherwise stated, the “vacuum cleaner” expression includes electrically operated vacuum cleaners which are used by pulling and pushing horizontally on the floor and have dry suction, dust bagged/dust bagless and household usage characteristics.

The main task of electric vacuum cleaners; by means of the suction force generated by the electric motor, to clean the space by vacuuming the dust and a certain volume of solid materials into the dust bag or dust reservoir in the machine. They are produced in various types and sizes; horizontal and / or vertical use, canister and upright models, dry and / or wet suction, dust-bagged and dust-bagless, household type or industrial type are the main different types of these machines. The electric vacuum cleaners in the scope of this invention are produced by domestic or foreign manufacturers, which can be purchased in market, are used by pulling and pushing in horizontal position (canister type standard floor vacuum cleaners), have dry suction, dust bagged/dust bagless and household usage characteristics.

Technically, there are electric vacuum cleaners specially designed to be carried on the back (called "Backpack Vacuum Cleaner" in international literature). Some patents taken in this context are given as examples; WO 1994027485 A1, US 6568026 B2, US 5267371 A, US 9259126 B2, US 5588177 A, CN 301291067, DE 29920968 U1, US 6151749 A, US 20060005346 A1. Since these types of designs are special, the sales price of these types of electric vacuum cleaners is considerably higher than the standard type floor electric vacuum cleaners.

In addition, some harnesses have been developed in the technique to facilitate the carrying of the above-mentioned backpack vacuum cleaners. Some patents taken in this context are given as examples; WO 2012125311 A1, WO 2017020063 A1, US 20120227209.

The object of this invention is; to enable the user can carry vacuum cleaners on his/her back with the help of the designed carrying apparatus. Thus, the difficulties of using the vacuum cleaner on the floor (such as an obstacle emerging when the machine is pulled, damage to the suction pipe due to stalling, scratching the hardwood floors, extra energy expenditure by the user for withdrawal of the machine) can be minimized. In addition, by using the vacuum cleaner on the back, an easier and faster vacuuming operation will be provided, which is less tiring for the user than it would be when pulled on the floor. The users of this invention will not have to bend their backs for any reason and will not experience twisting or sudden sharp movements while the vacuum is running because the upper body is kept upright. Thus, for the users, a reduction in the back pain caused by the vacuuming by the traditional methods will be seen.

By means of this invention, canister type floor vacuum cleaners can be strapped on user’s back, thus this method will make the home cleaning process easier and will save time and labor. The same benefits mentioned in the above paragraph will also be provided for some crowded places where the vacuum cleaner usage is difficult by pulling on the floor like cinemas, theaters, restaurants, cafés, meeting / conference rooms, prom / wedding halls, garage areas, schools, dormitories, stairwells and elevators, hotel areas, public transportation vehicles, cars, trains, planes, buses, ferries etc. Furthermore, by using of this invention the cleaning of two or three storey detached houses and villas will be easier as well. Especially, this invention will make easy the vacuuming process of tight spaces, up and down stairs, under and on top of furniture and many hard to reach corners.

Backpack Electric Vacuum Cleaners, which are available for sale in the market, have higher sales prices because of their special design than standard type floor vacuum cleaners. Also when necessary, Backpack Electric Vacuum Cleaners cannot be used by pulling and pushing on the floor. Another object of the present invention is to enable the use of home-type affordable electric vacuum cleaners instead of the special design Backpack Vacuum Cleaners at 1/2 to 1/3 of the selling price of the Backpack Vacuum Cleaners in the market.

The invention is designed as two different types;

The First Type of the Invention (Type A): Without using the original electric cable of the vacuum cleaner, the invention will take the energy from the city grid by using the electric cable which can be wrapped on its side. In the vacuuming process to be carried out with this invention, vacuum cleaner can be used continuously without changing the electric socket as much as the length of electric cable (maximum 15 m.) included in the invention. The first type of invention will have properties such as being lighter, having a simpler structure and more economical than the second type of the invention. This type of invention is designed primarily for household usage.

The Second Type of the Invention (Type B): Apart from the existing original cable drum in the vacuum cleaner, there is also a cable drum with a slip ring in the second type invention. This additional cable drum provides a long cable length (maximum 50 m.), which allows the vacuum cleaner to receive energy from the city grid without extending its own electrical cable. Thus, owing to the long cable length included in the invention, vacuuming process can be carried out by utilizing a single electrical socket in the area being cleaned or by changing the electrical socket in the least amount. This feature will save time and labor for the user during the vacuuming process. This type of invention is designed primarily for industrial usage.

For both Inventions (1A and 1B), all material like cables, plugs, sockets, bolts, washers etc. will be used comply with international standards.

General Description

The surface of the Invention (1A and 1B) may be left as it is, coated anodically or painted. In addition, a more aesthetic appearance can be obtained by covering its surface with fabric.

The Invention (1A and 1B) will be made of light metal (aluminum etc.) sheet with a thickness of 1 or 1,5 mm in order to lighten the construction and the assembly. The first line of Table 1 contains approximate weights of the Invention (1A and 1B). Maximum free weights performed from the solid invention models without vacuum cleaner and electric cable are 2 kg. for Invention Type A and 4 kg. for Invention Type B. Furthermore, construction of the Invention (1A and 1B) can also be made from plastic (PEEK, PP, PA, PE, POM, PC, TPE, PS, PPS, ABS etc.) or composite material (carbon fiber, fiberglass etc.). With this method, it is evaluated that the weight of the invention can be further reduced.

The average one meter weight of "3x1,5 mm2 / H05VV-F (TTR) type “PVC Insulated Multi Core Flexible Installation Cable" calculated as 109 g. according to production catalogues of 13 Turkish and 12 well-known International Companies. The second line of Table 1 contains approximate weights for Invention Type A’s max.15 m. power cable and Invention Type B’s max. 50 m. power cable.

The average weight calculated as 6.462 g. according to vacuum cleaners sold in the market of Turkey (69 different models of 6 different international companies)(Third line of Table 1)

As given in Table 1; the maximum weight of the invention, the average weight of the electric cable and the average weight of the vacuum cleaner are summed to determine the total weight of the invention. According to this calculation; the total weight of Invention Type A is approximately 10.000 g. and the total weight of Invention Type B is approximately 16.000 g.

In scope of this patent study, according to the rules of ergonomics, a research has been carried out on how much weight the human can safely carry on his back. In this way, The American Academy of Pediatrics recommends that a child’s backpack weigh no more than 20 percent of a child’s weight. Similarly, according to backpacking and hiking rules for adults, a loaded backpacking pack should not weigh more than about 20 percent of your body weight.
