Description

Technical field to which the invention relates

The invention belongs to the field of equipment for the separate collection or disposal of waste or other garbage from the household or industry, and according to the international classification of patents it is closest to B65B 67/12 indicated as bag holders, i.e. stands or frames with means for lifting bags, for easier filling with objects or material.

Technical problem

Nowadays, more and more attention is paid to the reuse of waste generated in the household and industry. Waste was usually disposed of at the place of origin and is still disposed of in one container or in one place, and for its beneficial use it is necessary to carry out subsequent selection and separation of waste, which requires additional costs. On the other hand, there is a trend to separate waste at the point of origin - plastic in one container, paper in another, tetrapak in the third, organic waste in the fourth container, glass in the fifth, and so on, depending on the types of waste to be sorted and amounts of waste that occur by individual type. For such selective disposal of waste, it is necessary to have the necessary disposal containers at the place of waste generation, which take up space because they have a considerable volume, and in them it is necessary to put special bags that need to be taken out of such a container after the bag is full, because the vehicles that would selectively collect waste from bins are not in use. Waste containers, especially in industry, are quite bulky and their delivery from the manufacturer to the end user carries increased costs due to the delivery of large volumes of products. Furthermore, nowadays, when the purchase of goods is moving to the Internet with a strong trend, where the delivery of ordered goods is done by mail or courier services, the issue of the volume of products to be delivered to the end customer has become important. Delivery of waste bins with a volume of 80 or 120 liters, which are usually products for waste disposal in households and industry, will very quickly fill the volume of the delivery vehicle, i.e. it will occupy it unnecessarily, which will mean increased delivery costs. A user who wants and intends to selectively dispose of waste needs at least four waste disposal bins. The problem is the delivery of such four buckets, especially the delivery costs.

The collapsible modular stand for bags for separate disposal of waste has a much smaller volume when transported between the manufacturer and the end user because it consists of detachable elements and occupies only a few cubic decimeters during transport.

Furthermore, it allows the user to assemble combinations of racks for one bag, two bags, three bags, four, six or eight bags from a set of elements, such as LEGO bricks, but according to the user's needs, that is, he can use only part of the elements, i.e. holders with a cover that they keep the bag open.

State of the art

A search of the state of the art, specifically the patent database PATENTOSCOPE, USPTO and ESPACENET shows that there are patented inventions or patent applications that solve the problem of putting waste in a bag in such a way that the bag has its own holder and in some cases a lid, as in patent application US 2010/0252694 A1 under the name of the invention FLEXIBLE BAG HOLDER, however, these inventions did not solve the issue of modular design. Patent US 5826830 TRASH BAND STAND is a protected invention for a holder for one bag, but it does not have a cover and does not have a solved method of fixing the bag to the frame as with this invention.

Patent US 5411229 entitled BAG HOLDER protects the invention of a holder for one bag, however, the design concept of such a stand does not allow combining multiple bag holders in a modular design.

Patents and patent applications that would include a collapsible multi-part modular rack for waste disposal bags have not been established, nor has it been established that such a product exists on the market.

Brief content of the essence of the invention

The subject invention relates to a collapsible modular rack for bags for separate (selective) waste disposal in the household and industry at the point of origin, which solves the primary problem of reducing the costs of delivery and product packaging, because the modular rack itself consists of several elements by combining which it is possible to assemble the racks for one, two, three, four, six or eight bags, depending on the needs of the user, and above all, the user can only use a holder without a metal structure that can be screwed into the wall or otherwise attached to a solid support (e.g. for a pole or for a tree in nature). Due to the fact that the stand is actually made in parts, when they are packed, they occupy an extremely small volume compared to the finished assembled product, which in the case of a stand for four bags takes dimensions that are larger than the dimensions 150 cm × 80 cm × 45 cm, and while these elements are packed, they take dimensions of 110 cm × 45 cm × 12 cm, which reduces the volume of the product more than 9 times.

Nowadays, buying products online is particularly attractive. However, such a purchase means that someone needs to deliver the product to the customer. In the case of a foldable modular bag rack, the customer is not supplied with an assembled product, but the same in modular prefabricated elements that are designed and manufactured in such a way that they require a minimum of dexterity from the customer in order to assemble the bag rack according to their needs, even if only for one bag or more of them, up to 8 bags in total, which is achieved by adding new modules to the basic rack assembly.

A secondary problem solved by this invention is the optimization of the production of such bag racks because at least nine finished products can be produced by combining different basic elements, thus reducing the operational costs of production, especially the costs of making production tools. For example, in order to produce a rack for four garbage bags, the same parts are produced as for a rack for two garbage bags with additional elements related only to the frame for holding the bag.

The third problem that is solved by this invention is the suitability of the bag carrier for the use of bags of different volumes. For example, if the utility company of one region uses bags for separate collection of waste with a volume of 120 liters, the holders for such bags will not be suitable for bags of 80 liters. This invention solves the issue of adjusting the height of the bag carrier itself so that one carrier can be adjusted at the same time, if, for example, it serves to hold four bags in such a way that two bags have a volume of 80 liters and the other two have a volume of 120 liters.

The fourth problem that is solved by the invention is the realization of the mobility of the entire structure, because regardless of the method of execution, four wheels can be installed on the lower part of the finished structure, and the bag racks in fact turn into carts that enable the separate collection of waste or any objects. It is even preferable to install a plate on the bottom above the floor on which the bottom of the bag can stand.

The basic elements of the foldable modular stand for bags for separate waste collection are two main supports that are made of rigid material, either metal, plastic, wood or other composite material, where each main support touches/rests on the base at least in two points. on which the stand itself is located, which ensures the stability of the entire stand, because in this way it is stabilized in four points. On each support there is one attachment for a horizontal support, so that, in relation to the type of modular stand that the user wants to assemble, a horizontal support can be placed on it, which can be performed in several ways. The horizontal support can be made compact or it can be made in segments that are connected by a suitable connector, which in the preferred version is connected with screws to the elements that make up the horizontal support, but it can also be connected with a screwless detachable connection, for example a plastic insert. In the preferred embodiment, the horizontal support is designed and produced in two basic segments, namely as a single horizontal support with two corners or a single corner horizontal support, whereby the single horizontal support with two corners is intended for the construction of narrow racks for one or two bags, with in that the stand for one bag can also be folded as a combination of two single corner supports, a single ordinary horizontal support and two connectors. Each horizontal support is made, regardless of the method of execution, with at least one handle for the vertical support, which is designed in such a way that the vertical support and the handle to which it is connected have the possibility of adjusting the total length, which makes it possible to put garbage bags of different sizes on the rack in question volume, so if, for example, it is an 80-liter trash bag, the total length of the handle for the vertical support and the vertical support is less than in the case of the length of the handle for the vertical support and the vertical support when they are used for bags for trash with a volume of 120 liters. In the preferred embodiment, this is achieved by predrilling holes of the appropriate diameter on the handpiece for the vertical support and on the vertical support itself, through which the desired height is fixed with a screw. This does not limit the possibilities that, for example, the vertical support can be pulled out telescopically from the handle for the vertical support, or, for example, the vertical support can be screwed into the support on the vertical support, and the length of the assembly that makes up the support for the vertical support and the vertical support is determined by the course of such a thread. support, and thus directly and accurately determines the height of the stand itself.

The elements of the modular rack for bags, primarily the main supports, attachments for horizontal supports, horizontal supports, vertical supports and attachments for vertical supports, and the connector are usually made of profiled materials of either square or circular cross-section, with the fact that such materials can be solid, but they can also be hollow to facilitate the construction of the stand. There is no obstacle for the elements of the modular bag rack to be made of material of a different cross-section, for example "I" or "U" profile.

In the best embodiment, the outer frame and the outer frame holder are made as one element, preferably from a durable material such as metal, with the inner frame being attached to the outer frame holder via a pin. If it is desired to keep the bag on the bag rack closed in order to collect insects or spread odors, or in the event of rain entering the bag, a cover can be attached to the said pin, which rotates around the pin and closes the opening of the bag while fitting over the inner frame of the bag. outer frame. In the preferred embodiment, both the inner frame, the cover and the pin are made by injection molding from weather- and UV-resistant plastic, but there is no obstacle to making them from metal or other suitable material.

In the preferred version, it is preferable that all metal parts, if they are made of sheet metal or steel profiles, are galvanized, but they can also be plasticized, or painted with weather-resistant colors. Versions where INOX is used or light aluminum profiles are also possible, and in the event that special aesthetic versions of the foldable modular stand for bags for separate disposal of waste are desired.

In addition to waste disposal, such racks, especially with built-in wheels, are also used in hotels for the collection of used bedding, but also in hospitals, nursing homes and elsewhere where it is necessary to selectively collect certain parts/items, and there is also a requirement for the mobility of such racks. , which in principle turn into a cart in that case.

A detailed description of at least one way of realizing the invention

One of the ways of realizing the invention is shown with the elements in Figure 2, and it is realized by making two pieces of the main support (2) from a square steel profile with a section of 18x18x1.5 mm, which is formed by bending it in two places at 90° in the form letter U height approx. 15 centimeters and Width approx. 50 cm. A piece of square steel profile 15x15x1.5 mm with a pre-drilled hole of 6 mm in diameter is welded to the part that forms the top of the letter U, which part forms the handle for the horizontal support (4). Then, two single angular horizontal supports (14) are made from a square steel profile 18x18x1.5 mm in such a way that the 60 cm long tube is bent at 90° in the middle. At one upper end of each pipe, a handle for the vertical support (8) is welded, on which two holes with a diameter of 6 mm have already been pre-drilled, so that they are made at such distances that depending on where the vertical support (12) is screwed into, we get a rack for bags of 120 liters (if screwed into a higher hole) or of 80 liters (if screwed into a lower hole). One hole with a diameter of 6 mm is drilled at the ends of the single corner horizontal support. To connect the single corner horizontal supports, a connector (10) is used, which is made of a square steel profile 15x15x1.5 mm and is 25 cm long. After that, two vertical supports (12) 50 cm long are made from a square steel profile with a cross-section of 18×18×1.5 mm, with one 6 mm diameter hole at one end, and two holes at the upper end. with a diameter of 6 mm. After that, two outer frames (16) are made from a steel sheet with a thickness of 1.5 mm by cutting and bending, each of which is joined into a "ring"11 at both ends by welding. The two holders of the outer frame (20) are made from a 1.5 mm thick steel sheet by stamping in such a way that they are immediately formed into the desired shape of the letter U, and immediately 6 holes with a diameter of 6 mm are punched on them. Each outer frame holder (20) is then welded to the outer frame (16). After that, all parts made of steel are subjected to galvanization. Two pieces of the cover (22), two pieces of the inner frame (16) and two pieces of the Pin (24) are made of plastic by injection molding into pre-made tools. Screws (26) with nuts (28) with a diameter of 6 mm are used to connect all parts into a whole. Then all the elements are connected according to the technologically indicated positions as shown in Figure 2, which results in a stand for two bags.

Another way of realizing the invention, as shown in Figure 3, is in the case of a stand for three bags, for which it is necessary to make the following parts using the procedure described in advance: 2 pieces of the main support (2) with a handle for the horizontal support (4), then 1 piece of single corner horizontal support (14) with socket for vertical support (8), one connector (10), three vertical supports (12), three inner frames (16) each, three outer frames (18) welded to the outer frame bracket (20) ), three covers each (22) and three pins each (24). In addition, it is also necessary to make a double corner horizontal support (32), which is made of a square steel profile with a section of 16×18×1.5 mm in such a way that the 100 cm long profile is bent to approx. 30 cm from one end at a 90° angle, one hole with a diameter of 6 mm is drilled at each end, and two attachments for the vertical support (8) are welded on the longer arm. Then the metal piece thus obtained is subjected to galvanization. Screws (26) with a nut (28) with a diameter of 6 mm are used to connect all parts into a whole, as in the earlier version. Then all the elements are connected according to the technologically indicated positions as shown in Figure 3, which results in a stand for three bags.

Further possible ways of realizing the invention are shown in Figure 3, which represents a modification in relation to the method just described, completely understandable from the drawing, the same for three bags.

Furthermore, three ways of carrying out the carrier for 4 bags are exposed as shown in figures 5, 6 and 7, for an expert in this field it is quite understandable in relation to the previously described ways of carrying out the invention.

Figure 9 shows the method of implementation of the invention so that the stand for one bag shown in Figure 1 can be turned into a stand for two bags, following the same procedure as described earlier, with the use of different elements.

Likewise, by adding new elements, where each set of new elements contains: cover (22), inner frame (16), outer frame (18) with outer frame holder (20) and pin (24) on stands made only for holding the bag from one side, a stand for four bags is obtained as shown in Figure 10, then a stand for 6 bags as shown in Figure 11.1 finally a stand for 8 bags as shown in Figure 12.

One of the ways of implementing the invention is as described in connection with Figure 2, with the fact that one wheel is installed on each leg of the main support (2) formed by the arms of the inverted letter nU", which results in a cart for bags.

Furthermore, another method of execution is to install a demountable tin plate at the top of the letter "U" on both main supports (2) in the earlier method of execution shown in Figure 2, with the bottoms of the bags sitting on that plate, as shown in Figure 13 In addition to the rack for bags made in this way, four wheels can be added to the arms of the inverted letter "U" of the main support, which results in a trolley with a support.
