The four legs 1a can be mounted on the mounting surface as they are. A guide member 4 of the winding body is foldably attached to one end of any one of the four legs 1a. This guide member 4 forms a ring portion 4a for bending a round bar to pass the winding body, and fold-back portions 4b formed at both ends of the round bar are rotatably attached to the ends of the leg 1a. In addition, a stop portion 5 for vertically stopping the guide member 4 is provided on the upper surface of the end portion of the leg 1a.

The wound body holding member 2 is a square tube, a round tube, a square bar or a round bar made of metal or synthetic resin, and is fixed with the four holding arms 2a opened in a substantially cross shape. Of the four holding arms 2a, two facing holding arms 2a are provided with a pair of studs 6 that can be stopped vertically and can be folded at appropriate positions of the holding arms 2a. .

The stud 6 is a rod-shaped member having an upper end bent at an angle of about 90 degrees to form a hook portion 6a. As described above, the stud 6 can be stopped vertically at an appropriate position of the holding arm 2a and held. The arm 2a is foldable and is attached to a support body 7 slidably attached to the holding arm 2a. That is, the columnar body 8 is axially supported by the support body 7 on the upper surface side of the holding arm 2a, and the stud 6 is inserted into the screw hole 8a of the columnar body 8.
The stud 6 is attached by screwing the screw portion 6b formed at the lower end of the. Therefore, when the stud 6 is rotated to be at a right angle to the holding arm 2a, the threaded portion 6b of the stud 6 is deeply screwed into the screw hole 8a of the cylindrical body 8 and the lower end of the stud 6 is placed on the upper surface of the holding arm 2a. The stud 6 can stop in the vertical direction at an appropriate position of the holding arm 2a.
A locking hole 10 is formed on the outer side of the holding arm 2a, and the stud 6 is rotated outward of the holding arm 2a to lock the hook portion 6a at the upper end in the locking hole 10. If this is done, the stud 6 can be stopped in the folded state on the holding arm 2a.

Further, a cushioning and binding body 11 is detachably attached to the upper surfaces of the pair of holding arms 2a to which the studs 6 are not attached. The buffer / bundle 11 can be, for example, a surface adhesive fastener having a large number of hook-shaped bodies 11a on one of the front and back surfaces and a large number of loop-shaped bodies 11b on the other side, and can be attached to and detached from the upper surface of the holding arm 2a. In order to attach it freely, a surface-adhesive fastener 12 having a large number of hook-shaped bodies 12a or loop-shaped bodies 12b on its surface is fixed to various places on the upper surface of the holding arm 2a. One of the front and back surfaces of the surface adhesive fastener may be adhered.

The shaft support portion 3 has a support shaft body 13 protruding from the upper surface of the center of the mounting support leg 1, and a bearing 14 mounted on the support shaft body 13.
The support cylinder 15 fixed to the center of the wound body holding member 2 is axially supported via the. A push nut 16 is used to prevent the bearing 14 from coming off the support shaft body 13, and a cap 17 is put on the support cylinder 15.

By doing so, the winding body feeding device of the present invention can horizontally rotate the substantially cross-shaped winding body holding member 2 above the substantially cross-shaped support leg 1 for the ground. In addition to being attached, the ground support legs 1 and the wound body holding member 2 can be held in a state of being superposed in a substantially cross shape.

When the winding body feeding device of the present invention constructed as described above is used, it is carried out as follows.

First, as shown in FIG. 1, the stud 6 is stopped vertically at an appropriate position of the holding arm 2a,
As shown in, the winding body W is mounted on the winding body holding member 2. That is, the hook portion 6a at the upper end of the stud 6 is removed from the locking hole 10, the stud 6 is rotated upward in the holding arm 2a, and is slid to an appropriate position of the holding arm 2a. The portion 6b is deeply screwed into the screw hole 8a of the cylindrical body 8 to bring the lower end of the stud 6 into contact with the upper surface of the holding arm 2a and stop the stud 6 in the vertical direction of the holding arm 2a.

Therefore, the wound body W is placed on the holding arm 2a thus configured, and the inner diameter portion of the wound body W is held by the studs 6, so that the wound body holding member 2 is wound. When W is mounted and the tip of the wound body W is passed through the ring portion 4a of the guide member 4, the wound body holding member 2 in this state.
While rotating the winding body W, the winding body W is guided to the ring portion 4 of the guide member 4.
It can be smoothly fed from a. In this case, a part of the bottom surface of the wound body W is in contact with the buffer / bundle assembly 11 attached to the upper surface of the holding arm 2a, and the buffer / bundle body 11 receives a buffering action. Even if the roll is swung out, the winding body W does not bounce up due to the reaction.

When the winding body feeding device of the present invention is not used, the following procedure is performed.

First, the mounting ground support leg 1 and the wound body holding member 2 are placed in a substantially cross shape, and the ends of the two opposing leg members 1a of the mounting ground support leg 1 and the winding are held. It is assumed that the end of the holding arm 2a to which the two opposed studs 6 of the body holding member 2 are attached is bound together with the tip end of the stud 6 by the buffer / bundle 11 (see FIG. 7). That is, from the state shown in FIG. 1, by loosening the screwing of the threaded portion 6b of the stud 6 into the screw hole 8a of the cylindrical body 8 and releasing the contact between the lower end of the stud 6 and the holding arm 2a, the holding arm is released. The stud 6 that has been stopped vertically to 2a is rotated to the holding arm 2a side so that the hook portion 6a at the upper end is locked in the locking hole 10, and the stud 6 is folded in the holding arm 2a. Stop it.
Further, the guide member 4 attached to one end of the leg body 1a of the mounting leg 1 is rotated to the back side of the leg body 1a and folded. Then, the holding arms to which the end portions of the two opposing leg bodies 1a of the mounting ground support legs 1 and the two opposing studs 6 of the winding body retaining member 2 are attached in a substantially cross-shaped overlapping state. A plurality of hook-shaped bodies 11 provided on the front and back surfaces of the surface-adhesive fastener are wound around the end portion of 2a, the tip portion of the stud 6 and the end portion of the guide member 4 by binding the buffer / binding body 11.
By engaging a with the loop-shaped body 11b, the buffer / binding body 11 is prevented from coming off from these end portions.

By doing so, it is possible to prevent the placing ground support leg 1, the wound body holding member 2, the stud 6 and the guide member 4 from moving in a state of being integrated together.

When the winding-body feeding device of the present invention is used again, the following procedure is performed.

First, in the state shown in FIG. 7, the cushioning and binding body 11 wound around the ends of the mounting ground support leg 1, the winding body holding member 2, the stud 6 and the guide member 4 is removed,
The buffer / bundle unit 11 is attached to the upper surface of the holding arm 2a. That is, one end of the buffer / bundle body 11 is rolled up to disengage the large number of hook-shaped bodies 11a and loop-shaped bodies 11b provided on the front and back surfaces of the surface-adhesive fastener, and the buffer / bundle body 11 is also released. Is removed from the ends of the above-mentioned ground support leg 1, wound body holding member 2, stud 6 and guide member 4. Then, a large number of hook-shaped bodies 11a or loop-shaped bodies 11a on the front and back surfaces of the buffer / bundle body 11 are attached to the holding arm 2
