The upper surface of the outer frame is raised to an arbitrary size from the upper surface of the frame, and screws are provided at both ends, so that it is possible to fold and attach and remove the garbage bag and to put in the garbage. It is about.

The present inventor, as an example of a mouth holding tilting stand for a folding garbage bag that does not require a container, in one example, an inner frame formed into a trapezoidal U-shape with an L-shaped steel material and a lower part expanded from the upper part to an arbitrary dimension. The outer frame, which is also shaped like a trapezoidal U with the same flat steel material, is placed outside by setting the upper surface of any dimension higher than the upper surface of the inner frame in the standing state, and the middle part can be pivoted It has been proposed that an inner frame cutout and an outer frame cutout are provided on the upper side of the inner frame and the outer frame, and an opening prevention stopper is fixed to a lower portion near the shaft attachment on the inner frame side.

The problem to be solved by the invention is that the example of the previous proposal uses an L-shaped steel for the inner frame and a flat steel for the outer frame. However, the L-shaped steel of the inner frame complements the flat steel of the outer frame in terms of bending strength. It is a form. Although the prototype was made in this form, it is easy to bend when the flat steel plate is thin. Therefore, as a countermeasure, it is necessary to increase the plate thickness or to reinforce the flat steel by beat processing or the like. In addition, the bag mouth is attached to the notch, but it will not come off because the bag mouth is always stretched for fixed use in a fixed place, but it turns out that it may come off easily when moved. did. Therefore, it is necessary to review all aspects such as using the same material having strength for the inner frame and the outer frame and changing the locking of the bag mouth from the notch to the protruding part. In the two examples, since 90 ° elbows are used for the inner frame and the outer frame, there is no problem in strength, and the bag mouth is attached to the screw provided on the upper surface so that it does not come off. However, in terms of production, the commercially available 90-degree elbow is limited, so the folding garbage bag stand that requires various sizes is limited in terms of cost and needs to be reviewed as in the example. It was. Accordingly, the problem to be solved by the invention is to provide a mouth-holding inclined stand for a steel pipe folding garbage bag of a form that has not been proposed in the past by summing up one example and two examples and consolidating the positive part of the example. It is to be.

The means for solving the above-mentioned problems is a trapezoidal U-shaped shape in which the lower part is expanded by an arbitrary size from the upper part where the left and right corner parts are molded by pressing a formable steel pipe with a bending pushing jig and a bending receiving jig at the corner part. Outside the inner frame, an outer frame, which is also formed in a trapezoidal U shape with a steel pipe, is set up outside the upper surface of the inner frame in an X-shaped standing state with the upper surface set to an arbitrary dimension, and the middle part can be pivoted A double-sided deterrent plate is attached to the shaft-attached portion and is attached to the shaft-attached member. The plate is fixedly attached to the shaft-attached member. Screw screws on the upper and left sides of the inner and outer frames, and pipe caps on the lower ends.

The both-side deterrent plate that locks the inner frame and the outer frame at a position where the inner frame and the outer frame do not open more than a certain distance is changed to a one-side deterrent plate that opens the inner frame and the outer frame only on one side, and is attached to the shaft mounting part. Attach at.

Extend the upper part of the inner frame and outer frame as much as necessary for the garbage bag, and screw the screws for the garbage bag at regular intervals between the left and right screws.

Casters are provided instead of the pipe caps attached to the left and right lower ends of the inner frame.

Normally, a pipe bender is used to bend a steel pipe, but the minimum bending radius is determined by the material of the steel pipe, and if it is bent beyond that, it will break. The mouth holding inclined stand of the steel pipe folding garbage bag of the present invention is formed by pressing the U-shaped corner portions of the inner frame and the outer frame with convex and concave corner bending jigs, so that the material and diameter of the steel pipe are adjusted. Regardless of the bending angle of the pipe bender, it can be molded at a bending angle. Therefore, it can respond to various uses by selecting the steel pipe of each size. In addition, since it is a folding type, it can be installed with a single touch when in use, and when used, the stand opens with the inner and outer frames tilted, but the locking plates on both sides that are attached to the shaft-attached part are located at a fixed position in both directions. Since the frame and the outer frame are locked, it is not necessary to consider the direction of opening according to the situation, and the stand does not fully open, so that the garbage bag can be easily attached. However, depending on the application, if only one side is required, a one-side locking plate is attached. Screws screwed to the upper left and right of the inner frame and outer frame can be securely attached to the mouth of the garbage bag at the head and torso parts, and the inlet is inclined so that it is easy to put dust. Even when moving the stand during work, the mouth of the trash bag is firmly stretched with screws, so it is difficult to remove.To remove, narrow both frames slightly, remove the mouth of the bag from the screws and frame, and raise the stand This can be done easily by lifting. In addition, bags with mouth straps such as PE sandbag bags and PF glass bags do not come off the stand because the straps are caught by screws. When not in use, the outer frame and the inner frame are rotated and united so that storage and carrying can be easily performed. This stand is for the purpose of holding the mouth of the bag open, the load of the object put in the bag is received by the ground, and both frames set the height dimension to hold the shape of the bag. Therefore, it is better to avoid increasing the dimensions and hanging the bag with screws, as the mouth of the bag may be torn or detached. However, in the case of a bag with a mouth strap, it may be suspended if necessary for work.

Although there are a wide variety of types of steel pipes, the steel pipes used in the present invention are mainly selected from aluminum pipes, stainless steel pipes, hot-dip galvanized steel pipes, etc. that do not rust. Aluminum pipes are lightweight and have good aesthetics, so they are suitable for putting relatively light chemical products, papers, fallen leaves, etc. generated indoors and outdoors with plastic bags. Stainless steel pipes and hot-dip galvanized steel pipes (agro-steel pipes, electric sewing irons, white gas pipes, etc.) are solid, so PE waste bags, PF glass bags, etc. are attached and waste materials generated indoor and outdoor work sites, construction sites, etc. Suitable for heavy objects such as earth, rubble, etc. In this case, stainless steel pipes are expensive (about 10 times that of hot-dip galvanized steel pipes) and should not be used unless specifically required.

A normal trash bag stand can only have one trash bag. In this stand, the upper part of the inner frame and the outer frame are extended by the required number of garbage bags, and if the required number of screws that hook the mouth of the garbage bag are screwed between them, multiple garbage bags can be attached to one stand. it can. Therefore, since it becomes an unprecedented form and various kinds of garbage can be put into a plurality of bags at a time, the work efficiency is greatly improved, and various applications can be handled.

The size of the stand is determined by the size of the garbage bag. In general, commercially available products such as 45 L, 70 L, and 90 L plastic bags for homes and offices, and standard products such as PE sandbag bags and PP glass bags mainly for offices and industries are used. Therefore, the manufacture according to the standard of each bag can be easily handled by changing the dimensions because the shape is the same.

Similarly, a trapezoidal U-shaped outer frame is formed on the inner frame of a trapezoidal U-shape formed using various steel pipes, and the upper surface of the outer frame is set to an arbitrary height higher than the upper surface of the inner frame in an X-shaped standing state. A part is pivotally attached to be rotatable. A restraining plate for preventing a certain degree of opening is attached to the shaft attachment portion, and a dust bag locking screw is screwed to the outer frame and the outer upper portion of the inner frame.

FIG. 1 is a cross-sectional view of a steel pipe folded waste bag with a mouth holding inclined stand, in which a steel pipe is formed with a bending push jig and a bending receiving jig at the corners forming the upper left and right corners of the inner frame 1 and the outer frame 2; FIG. 2 is a longitudinal sectional view. Normally, when bending steel pipes, the minimum bending radius is determined by the pipe material, hardness, and diameter, and the processing is performed by a pipe bender. If further bending is required, an elbow is used to weld the steel pipes at both ends or the steel pipe. There is a method of cutting and finishing both ends. In the present invention, the minimum bending radius of various steel pipes used cannot cope with the bending required for the invention. Also, welding of elbows and steel pipes and cut welding of steel pipes are not qualified methods in terms of production and cost. Therefore, the bending radius required by the present invention is such that if the steel pipe is pressed with a corner bending push jig and a bending receiving jig, the inside of the steel pipe is recessed along a semicircle and escapes to both sides. Possible bending radii can be obtained. If this jig is manufactured in accordance with the diameter of the steel pipe, it is possible to easily perform bending work more than that performed by a pipe bender with any kind of steel pipe.

FIG. 3 is a perspective view of a mouth holding inclined stand of a steel pipe folded garbage bag. A trapezoidal U-shaped inner frame 1 formed by pressing a steel pipe with a bending push jig and a bending receiving jig at the corner, and an outer frame 2 of the same shape molded with an arbitrary dimension higher than the surface of the inner frame 1 It is installed and pivotally mounted by a shaft mounting member 3 so as to be rotatable. On both sides of the shaft attachment, both sides of the upper and lower sides are symmetrical and both sides deterrence plates 4 which interfere with each other when the inner frame 1 and the outer frame 2 are opened and which do not open on both sides more than a predetermined amount are attached. Therefore, the inner frame 1 and the outer frame 2 are not fully opened when the garbage bag is attached. Screws 6 that can securely hook the bag mouth are screwed to the upper left and right of the inner frame 1 and the outer frame 2, and a pipe cap 7 is attached to the lower end. It should be noted that the shaft mounting member 3 at the shaft mounting portion must be a method in which a bolt, a nut, and both ends of the shaft are securely mounted so as not to loosen. In addition, the pipe cap 7 is illustrated as being covered from the outside of the pipe. However, the pipe cap 7 may be a round plug that is knocked into the pipe and capped.

FIG. 4 is a front view of a folded steel tube folded trash bag holding mouth tilting stand. Since the inner frame 1 and the outer frame 2 are pivotally attached by the pivot member 3, they can be integrated when folded. The AA cross section is a cross-sectional view of the axially attached portions of the inner frame 1 and the outer frame 2. The both-side deterrent plate 4 that is attached to the inner frame 1 and the outer frame 2 that are attached to the shaft has an upper portion that is narrower than the lower portion than the inner frame 1 and has an opposite shape to the outer frame 2. Therefore, the inner frame 1 and the outer frame 2 are respectively locked to the both-side deterrent plates 4 so that they do not open more than a certain amount.

FIG. 5 is a front view of a steel pipe folded garbage bag with its mouth open and tilted stand that is folded in one direction.
In the third embodiment, the both-side deterrent plate 4 can be opened on either side, but depending on the use conditions, only one side may be opened. The B-B cross section is a cross-sectional view of the axially attached portion where the one-side deterrent plate 5 is attached to the inner frame 1 and the outer frame 2. If the one-side deterrent plate 5 formed in a U-shape and provided with a predetermined notch capable of operating the inner frame 1 in the lateral width portion with an arbitrary size is attached to the shaft attachment portion, the outer frame 2 is placed on the upper portion of the one-side deterrent plate 5 Because it is in contact, it opens only on one side.

FIG. 6 is a side view in which a general garbage bag is attached to a mouth holding inclined stand of a steel pipe folded garbage bag. Since the upper surfaces of the inner frame 1 and the outer frame 2 are inclined and the mouth of the garbage bag is securely hooked on the screw 6 and is stretched between the inner frame 1 and the outer frame 2, even if the garbage bag is lifted with dust It is hard to come off, and the entrance is also inclined so it is easy to put in trash. In addition, bags with mouth straps, such as PE sandbag bags and PF glass bags, enter the body of the screw 6 so that the mouth of the bag is securely held and does not come off. To remove the garbage bag after throwing it in, the upper part of the inner frame 1 and the outer frame 2 is slightly narrowed, the mouth of the garbage bag is removed from the screw 6, and if both frames are lifted up, only the garbage bag remains, so it is easily removed. be able to. Note that this stand is an invention for the purpose of opening and holding the mouth of the bag, and it is desirable to set a size to receive the load of an object put in the bag on the ground. In the state where the size is increased and the bag is suspended with the screw 6, if the bag is weak, the mouth of the bag is torn and a load is applied to the stand, so it should be avoided except in special cases.

FIG. 7 is a front view in which a plurality of screws 6 are screwed onto the upper portion of the mouth holding inclined stand of the steel pipe folded garbage bag. A plurality of garbage bags can be mounted by providing screws 6 for hooking the mouths of the garbage bags at regular intervals on the upper surfaces of the inner frame 1 and the outer frame 2. The number of trash can be determined based on the fixed pipe size and the trash bag size in consideration of workability.

FIG. 8 is a side view in which casters 8 are provided at the left and right lower ends of the inner frame 1 of the mouth holding inclined stand of the steel pipe folded garbage bag. If the mouths of the garbage bags attached to the inner frame 1 and the outer frame 2 can withstand the load of the thrown-in garbage, the upper and lower casters 8 on the left and right sides of the inner frame 1 can be provided to lift the upper surface of the outer frame 2 during use. Can be easily moved. In addition, the lower end of the outer frame 2 is grounded and functions as a brake and does not move freely.

Garbage is generated at home and outside, along roads, parks, river beds, offices, factories, public facilities, and various other places. Most of these trash is put in trash bags. Garbage bags include plastic bags that are generally used, PE sandbag bags with a mouth strap, and PP glass bags that are often used at construction sites and disaster sites for industrial use. Compared with conventional stands, the proposed steel tube folding waste bag mouth holding tilt stand can easily open and close the stand and attach and detach the waste bag when collecting waste, as well as check the waste in the bag from the outside. Therefore, safety is high and work can be performed efficiently. Therefore, there is a high possibility of using it for garbage generated everywhere.

The steel pipes used are mainly aluminum pipes and hot-dip galvanized steel pipes, and can be mass-produced at low cost by pressing using a special bending jig. For other stainless steel and special steel pipes, pressing can be performed in the same way, so it can be used for various purposes if necessary.

In the event of a disaster, sandbags are necessities for preparation, response, and clean-up. Normally, a pair of two people deal with sandbags. If the sandbag bag is used, 6 people can work alone by simple calculation. In addition, since the inlet is inclined, the working efficiency is greatly improved, and one-touch-like assembly and folding can be performed, so that when not in use, the storage space can be reduced and transportation can be easily performed.
