Description

The invention relates to light industry and can be used in the manufacture of household bags for carrying various small loads.

Known household bag for carrying small loads, in which the handles are made in the form of loops of a belt.

Its disadvantage is inconvenience when using, when the bag is fully loaded and the plane of the center of gravity is symmetrical to the front and back wall.

Closest to the invention is a household bag for carrying various household goods. The bag contains a flexible container with an inlet, bounded by rectangular front and rear walls, which are interconnected with rectangular side walls and a base. The handles are made in the form of belt loops, and one is fixed on the front, and the other is on the back of the bag.

The disadvantage of such a bag is inconvenience when using when the bag is loaded to the top, and in this case its center of gravity does not lie in the plane of symmetry of the front and rear walls and cyiytKy turns. In addition, the handles that represent the loops of fabric are strongly pressed on the arm, and besides the efforts to keep the bag on weight, it is necessary to expend the effort to squeeze the handles. The presence of the torque causes an uneven force on each handle.

The aim of the invention is to improve the usability of the bag by reducing the effort when carrying it, which is expressed in the elimination of the compressive force.

and a torque compensating force and facilitating bag filling.

The goal is achieved by the fact that in a master bag comprising a body formed by the front, back, side walls and bottom, a pair of loops fixed on the front and back walls, the attachment points of which are symmetrical about the vertical axis, each loop is fixed at one end on the front wall and the other on the rear wall, while the loops are provided with a rigid handle with slip nodes to allow free movement along both loops, and the distance between the slip nodes is equal to the distance between the ends of two pet eh attached to one of the walls. In order to facilitate bag filling, the length of each loop is determined by the ratio L P / 2 - I, where L is the length of the loop; P is the perimeter of the inlet of the bag; I is the distance between the ends of the loops.

Figure 1 shows a host bag; figure 2 is also a top view.

The host bag comprises a body which is formed by the front wall 1, the back wall 2, the side walls 3 and 4 and the bottom 5. The handles of the bag are made in the form of hinges b and 7, which are fixed at one end to the front wall 1 and the other at the back wall 2 symmetrically relative to the vertical axes of the side walls and parallel to each other. On the loops, with the possibility of free movement along them, a rigid handle is installed, 8 s. nodes 9 and 10 slip, which provide free movement along both loops.

The operation of the bag is carried out as follows.

An inlet is used to place the item in the bag. The handle 8, the slippery knots 9 and 10, slide along the loops 6 and 7, is retracted to the extreme position, as shown in Fig. 2, and the loops are positioned outside the perimeter of the inlet. For this, the size of the loops is chosen from the ratio L P / 2 - I. In this case

The ratio is fully open inlet. After the bag is filled to the top, the handle 8 is taken, which, sliding along the loops 6 and 7, is automatically set in that position, when the center of gravity of the whole load in the bag will be located in a plane parallel to the carrier’s leg, and In this case there will be no torque. Pen 8 can

make a convenient form. Compressive force disappears completely. .

Thus, the proposed bag is more convenient to use and reduces the EFFORTS necessary for carrying the load, which

Especially important when carrying loads for a considerable distance.
