Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement in a sheet hanger for hanging sheets made of plastic film or the like so that they can be taken out.

[Conventional technology]

Films such as vinyl chloride and polyethylene used for packaging in superstores and shops, or sheets such as packaging bags made from these films, are stacked in large numbers and placed in a drawer or shelf. Because they are slippery, they tend to slip, making it impossible to organize them properly, causing them to lose their shape or fall apart.

Therefore, as shown in FIG.
A fixing rod 1 is provided with mounting portions 1c on each side portion 1b, and side pieces 2b facing rear are provided on both ends of a horizontal hanging portion 2a, and the side pieces 2b are connected to the side portions 1b. A seat hanger 4 has been developed, which is composed of rotating rods 2 pivotally connected to the side portions 1b of a fixed rod 1, and is configured such that the seat 3 is held between the receiving portion 1a and the hanging portion 2a. , Jitsugan Showa 60-115820
(Utility Model Publication No. 62-24766) has been applied for utility model registration.

[Problem that the invention attempts to solve]

In the sheet hanging device according to the above application, when the number of sheets hung on the hanging device decreases, the sheets cannot be reliably pinched and it becomes difficult to take out the sheets.

The above-mentioned hanger is made of a rod member, and the mounting portion has many bent parts, which requires many manufacturing steps and complicates the structure.Furthermore, the receiving portion and the hanging portion are both made of rod members with approximately the same diameter. Therefore, when replenishing sheets, errors such as replenishing the sheet into the receiving section may occur.

[Means for solving problems]

The present invention was made in order to solve the problems of the prior art, and the distributed sheets are placed between a receiving member fixed to a support plate and a hanging portion of a rotating member facing the receiving member. A new sheet that prevents the sheet from falling off by holding one side in place and utilizing the rotational moment generated by the sheet's own weight and the weight of the rotating member, and also has a simple structure that ensures sheet replenishment and removal. The purpose is to provide hanging equipment.

As a means to achieve this object, the present invention provides a receiving member between a pair of left and right supporting plates arranged in parallel in the front and back direction with a predetermined interval, and a receiving member is provided between the supporting plates at the rear upper part of the receiving member. To provide a seat hanger, characterized in that a rotating member formed in a crank shape with a part and a mounting part is pivotally supported through the mounting part so that the hanging part can rotate in the front-rear direction. It is something.

[Effect]

One of the sheets suspended from the hanging part in the sorted state is held between the hanging part and the receiving member with a clamping force due to the rotational moment of the hanging part, and this clamping force is equal to the weight of the bundle of sheets. Therefore, when the number of sheets is large, a strong clamping force is applied, and even when the number of sheets is small, they are held by the rotating member's own weight and frictional force, and do not slip off.

When taking out the sheet, it can be easily pulled out from the hanger by pinching the outermost sheet upward.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 7.

FIG. 1 is a perspective view of the main parts of the seat hanger of the present invention. In FIG. 1, the seat hanger consists of a support plate 5, a receiving member 6, and a rotating member 7.

As shown in FIG. 1, the support plate 5 is formed by bending the upper and lower edges of a plate material 51 outward in a U-shape. Therefore, even if the plate material 51 is thin, the bent portions 52 at the upper and lower edges of the U-shape serve as reinforcing ribs to supplement the strength.

Notches 53 for supporting the rotating member 7 are cut out at predetermined intervals in the inner corner of the bent portion 52 on the upper edge.

The vertical side of the notch 53 is the mounting portion 7 of the rotating member 7.
3 (FIG. 2), and the bottom shape is a semicircular arc that follows the outer circumference of the mounting portion 73 (FIG. 1).

On the other hand, the horizontal side of the notch 53 has a width d sufficient to allow the mounting portion 73 to pass vertically (Fig. 1), but when the mounting portion 73, that is, the rotating member 7 is set, The mounting portion 73 has a shape with a horizontal length l ₁ shorter than the length l ₂ by which the mounting portion 73 projects outward (FIG. 2).

A plurality of these notches 53 are provided in the bent portion 52 of the upper edge, and their positions and intervals are intermediate positions where the receiving members 6 are arranged side by side.

The support plates 5 configured in this way form a left and right pair, and are arranged side by side in the front-rear direction with a sufficient interval for setting the rotating member 7 from which the seat is to be hung (not shown). These left and right support plates 5 are connected by a receiving member 6.

As shown in FIGS. 1 and 2, the receiving member 6 is made by folding back the upper and lower edges of a thin plate 61, bending both ends 90 degrees to the back, The outer surface of the portion 62 is joined to the inner side of the support plate 5.

The joining position is such that the hanging portion 71 of the rotating member 7 abuts and hangs against the upper edge of the receiving member 6, and the plate surfaces of the receiving member 6 are arranged to face each other in the vertical direction.

In this way, the receiving member 6 is stretched between the left and right support plates 5.

Note that instead of using a thin plate material for the receiving member 6, a thick plate material with a predetermined strength may be used (not shown). In this case, the upper and lower edges of the plate are not folded back and are fixed as they are between the left and right support plates 5.

As shown in FIG. 3, the rotating member 7 consists of a hanging part 71 that faces left and right, an arm part 72 that continuously faces front and back from both sides, and each arm part 72 on the left and right sides of the hanging part 71, as shown in FIG. It is further bent into a crank shape and is further continuously bent into a mounting portion 73 facing outward.

The length of the hanging portion 71 is sufficient as long as it can hang the sheet, but the length can be within the distance between the left and right support plates 5 at most.

The arm portion 72 is set to have a length that connects the center 0 of the notch 53 and the upper edge 63 of the receiving member 6, as shown in FIG. It is desirable to select the thickness of the sheet bundle within that length.

The length of the mounting portion 73 is not limited, but it is required that the length of the mounting portion 73 is at least such that the left and right mounting portions 73 can simultaneously fit into the notch 53 and pivotally support the rotating member 7 . If the length of the hanging part 71 becomes large, the length of the mounting part 73 becomes small, and conversely, if the length of the hanging part 71 becomes small, the length of the mounting part 73 becomes large.

In order to use the hanging device according to the present invention constructed as described above as a hanging device for a sheet, for example, a polyethylene bag 81, there are modes of use as shown in FIGS. 6 and 7.

FIG. 6 shows a mode of use in which a plurality of rotating members 7 are rotated forward (clockwise or to the right).

In this case, there are various ways to set the polyethylene bag 81, but one example is as shown in FIG. The mounting portion 73 of the rotating member 7 is inserted and attached, and the arm portion 72 is kept in a horizontal state.

On the other hand, the bundle 8 of polyethylene bags 81 is folded in half, and the inside of the fold is divided and hung on the hanging part 71 of the rotating member 7.

The rotating member 7 rotates downward about the mounting part 73, and the bundle 8 is sandwiched between the hanging part 71, the receiving member 6, and the upper edge 63, and at the same time, the outer lower part of the bundle 8 is It hangs down along the front side of the member 6.

In this mode of use, a bundle of polyethylene bags 8 is set in advance on each hanging portion 71 of all rotating members 7 with a thickness such that the bundles are joined to each other in the front and back, and first, the polyethylene bags 81a of the front bundle 8a are taken out. , if a gap is created between the bundle 8a and the rear bundle 8b,
If the polyethylene bag 81b of the rear bundle 8b is also taken out in the same manner, the polyethylene bags 81c of the rear bundle 8c can be taken out in sequence.

To take out the polyethylene bag 81, the sixth
As shown in the figure, by picking up the upper surface of the outermost polyethylene bag 81a with fingers 9, only one bag can be pulled out while keeping the rest stationary.

Then, like the frontmost bundle 8a in Fig. 6,
When the number of polyethylene bags 81a decreases, the finger 9 on the flipping side is lowered deeply and the polyethylene bag 81a is flipped up while pressing the front surface toward the receiving member 6 on the back side.

In this way, even if the number of polyethylene bags 81a gradually decreases and the effective diameter D generated at the folded portion of the bundle 8a decreases, the stroke of the finger required to turn up the outermost polyethylene bag 81a will be sufficient. Even if the number of sheets in the bundle 8a reaches the final number, the outermost polyethylene bag 81a can be secured.
By picking up the top surface of the polyethylene bag 81a and keeping the remaining polyethylene bag 81a stationary, only one bag can be pulled out.

Incidentally, if the force relationship acting on the hanger A is analyzed, it will be as shown in FIG. 6.

That is, assuming that the entire weight W of the bundle 8 of polyethylene bags 81, the weight W of the rotating member 7, and the length L of the hanging part 71, the moment M applied to the hanging part 71 is
is M=(W+w)+L, which means that the same force acts as a reaction force on the receiving member 6, and the bundle 8 of polyethylene bags 81 is clamped by these forces.

Therefore, as the number of polyethylene bags 81 increases, that is, the greater the weight W, the larger the force proportional to this is held, which is convenient. , even if it decreases, the weight W of the rotating member 7
is applied, and due to the frictional force, the polyethylene bag 81
can prevent falls.

FIG. 7 shows another usage of the hanger according to the present invention.

FIG. 7 shows a system in which a bundle 8 of polyethylene bags 81 is taken out one by one by using one rotating member 7 and holding a bundle 8 of polyethylene bags 81 between the left (rear) receiving member 6 or the right (front) receiving member. It is.

When the bundle of polyethylene bags 81 is large, or when the number of polyethylene bags 81 decreases, the bundle 8
The method of taking out the polyethylene bag 81 when the effective diameter D formed at the folded portion becomes smaller is the same as in the case of the use mode shown in FIG. 6 described above.

In this mode of use, based on the position of the worker,
One rotating member 7 is attached to the front or rear receiving member 6.
It is used by rotating it appropriately so that it collides with the object.

[Effect of idea]

As described above, the seat hanger according to the present invention allows one of the distributed sheets to be held between the receiving member fixed to the support plate and the rotating member pivotally connected to the support plate. Therefore, the sheet can be held with a large force in proportion to the amount of the sheet, so it will not slip off and the sheet can be taken out easily and reliably from beginning to end. Furthermore, there are no errors in setting.

Moreover, the structure of the hanger is simple, easy to manufacture, and easy to repair.
