FIG. 1 shows a configuration example of a bandage winding device.
The bandage winding device is formed by integrally forming a winding mechanism 1 that winds the bandage 8 around a winding shaft 12 and a clamp portion 2 that fixes the winding mechanism 1 to an object such as a table 9. These materials are iron plates.

The winding mechanism 1 is composed of an integral sheet metal in which the side plate 10 and the side plate 15 are arranged perpendicular to the bottom plate 16 and in parallel with each other. Guides 13 and 14 for guiding the bandage 8 are arranged in parallel and fixed to the lower portions of the side plate 10 and the side plate 15 (height h from the bottom plate 16). That is, the tips of the guides 13 and 14 are fitted into the two holes 103 formed in the bottom plate 10, and one end is fastened and fixed to the side plate 15 by the nut screw 142. (The nut screw on the guide 13 side is not visible due to the shadow of the movable plate 11.) The cross-sectional shapes of the guides 13 and 14 are cylindrical.
The side plate 10 and the side plate 15 may be integrally formed with the bottom plate 16 by welding. Further, since the bottom plate 16 serves as a base for the side plates 10 and 15, it can also be referred to as a base portion in which the side plates 10 and 15 are coupled.

  The movable plate 11 is fitted to the guides 13 and 14. On both sides of the movable plate 11, guide stays 131 and 141 that prevent and support the movement of the guide are arranged. The movable plate 11 is guided by the guides 13 and 14 and can move in the direction of the arrow Y. The movable plate 11 is stopped at a desired position according to the width of the bandage 8, and the movable plate 11 is moved by the guide stays 131 and 141. To support.

  A pair of bearings 121 are disposed at the upper ends of the side plate 10 and the movable plate 11, and a winding shaft 12 that winds the bandage 8 is fitted to the pair of bearings 121. An arm 123 to which a handle 124 is fixed is fixed to one end (right end) of the winding shaft 12 with a screw 122. The cross section of the winding shaft 12 has a polygonal shape, for example, a quadrangular shape.

  The clamp portion 2 is formed by bending the bottom plate 16 into a U shape, and the U portion is set on the table 9. The bandage take-up device is inserted by pressing the back side of the table 9 with a fastening screw 21 fitted from below the bottom plate 16 and pressing the back side of the table 9 with a washer (not visible in FIG. 1 because it is on the back side of the table 9). It is fixed to the table 9. The U-shaped upper end of the bottom plate 16 is formed with a curved surface (hereinafter referred to as an R (R) portion 22), and the bandage 8 is wound while the bandage is pressed against the R portion 22, whereby the wrinkles of the bandage are stretched. .

  In this embodiment, the positional relationship seen from the side surfaces of the winding shaft 12, the guide 13 and the guide 14 is an isosceles triangle (base d) (easily understood with reference to FIG. 2). That is, the winding shaft 12 is disposed at the center upper portion with respect to the guide 13 and the guide 14 serving as the bottom sides. Due to this arrangement relationship, when the bandage is wound, the force applied to the winding shaft 12 acts evenly on the guide 13 and the guide 14 so that the bandage can be wound stably.

FIG. 2 is a side view of the bandage winding device showing the bandage winding operation.
The bandage 8 is guided by the operator by hooking the guide 13 and the guide 14 in this order from the front side of the table 9, and finally the tip of the bandage 8 is manually guided to the winding shaft 12. First, the bandage 8 is wound around the winding shaft 12 while slowly rotating the handle 124 clockwise with the right hand. The arrow indicates the winding direction.

  One of the features of this embodiment is that a sufficiently strong bandage winding force can be obtained by considering the guidance of the bandage 8. That is, the bandage 8 is guided from the R portion 22 of the clamp portion 2 fixed to the table 9, folded back from the back guide 13 of the winding mechanism 1, and passed through the lower side of the front guide 14 to pass the winding shaft. 12 is guided. When winding the bandage 9, the operator positions the hand of the bandage 8 slightly below the R part 22 of the clamp part 2 and turns the handle 124 so that the R part 22 can squeeze the bandage 8. The wrinkles of the bandage 8 are stretched by the ironing of the R portion 22 and sufficiently spread in the width direction of the bandage. Further, the bandage 8 is folded 180 degrees by the guide 13 and guided to the front guide 14. Compared to the case where the bandage 8 is guided in another direction (for example, upward) without being folded back 180 degrees by the guide 13 (although it is a tentative example), the bandage 8 is guided by the guide 13 as in this embodiment. The bandage 8 is further wrinkled and given sufficient tension by being guided by folding back 180 degrees. Furthermore, sufficient tension is applied to the bandage 8 by applying a squeezing force to the bandage 8 at two locations of the guide 13 and the guide 14. Since the bandage 8 is wound around the winding shaft 12 in this state, the wound bandage 8 becomes sufficiently hard as a result of sufficient tension.

Further, the guide 13 and the guide 14 are arranged in a line-symmetrical position with respect to the vertical line from the winding shaft 12 (that is, the winding shaft 12 is positioned at the upper center of the two guides 13 and 14). Therefore, when winding the bandage by turning the handle 124 clockwise, a force is evenly applied to the front and rear guides 13, 14, and it is difficult for rattling to occur between the guides 13, 13 and the winding shaft 12, and it is stable. The bandage can be wound up.
When the winding of the bandage 8 is completed, the winding shaft 12 is pulled out from the bearing 121. This makes it possible to take out the bandage that is uniformly tightly wound.

  The example shown in FIG. 2 is an example of a method of winding a surface bandage that is usually used. On the other hand, since elastic bandages and elastic bandages have sufficient elasticity and elasticity, using the winding method of FIG. 2 is not preferable because the tension at the time of winding becomes even stronger. Therefore, it is preferable that the elastic bandage or the like is wound around the winding shaft 12 by guiding only the front guide 14 (or only the back guide 13). In short, the bandage winding device according to this embodiment can be used for winding various bandages.

The structure of Example 2 is shown in FIGS.
In the second embodiment, the clamp portion 2 is separated from the winding mechanism 1 in the configuration of the first embodiment, and is used as another component. This separate part is called clamp 2 '. 4 shows the configuration of the winding mechanism 1, FIG. 5 shows the configuration of the clamp 2 ′, and FIG. 3 shows the state where the winding mechanism 1 is fixed to the table 9 by the clamp 2 ′.

  In the first embodiment, as shown in FIG. 1, a bottom plate that joins the side plate 10 and the side plate 15 of the winding mechanism 1 is formed integrally with the clamp portion 2. On the other hand, in Example 2, as shown in FIG. 4, the bottom plate 16 that integrally couples the side plate 10 and the side plate 15 of the winding mechanism 1 and the upper plate 23 of the clamp 2 ′ are separate members.

The clamp 2 ′ can be formed by bending a single plate into a U shape. Furthermore, in order to save the material cost of the clamp 2 ', it can be configured as shown in FIG. That is, an upper plate 23 extending left and right, and a lower plate 24 positioned in the center and parallel to the upper plate 23 are integrally formed with the front plate 25.
A retaining screw 21 is fitted into the central portion of the lower plate 24, and the back side of the table 9 is pushed by a washer 212 attached to the tip thereof.

  As a feature of the second embodiment, the width of the clamp 2 ′ is equal to the distance w inside the side plate 10 and the side plate 15 of the winding mechanism 1. That is, since the side portion of the upper plate 23 of the clamp 2 ′ is closely fitted between the side plate 10 and the side plate 15 of the winding mechanism 1, the side portion of the upper plate 23 of the clamp 2 ′ is the side plate 10 and the side plate 15. Can firmly support the inside. Therefore, the side plate 10 and the side plate 15 can be prevented from rotating left and right when the handle 124 is rotated, and the winding shaft 12 can be prevented from shaking.

  Further, as a feature of the second embodiment, the bandage can be wound with a uniform hardness regardless of whether the operator is right-handed or left-handed. That is, the right-handed worker fixes the winding mechanism 1 to the table 9 with the clamp 2 'as shown in FIG. On the other hand, a left-handed worker turns over the right and left sides of the winding mechanism 1 (that is, with the guide 13 side forward (the guide 14 on the back side)) and is fixed by the clamp 2 '. In this case, the positional relationship seen from the side surfaces of the winding shaft 12 and the guides 13 and 14 is an isosceles triangle, and the heights of the guides 13 and 14 (distance from the bottom plate 16) are equal. is there. Thereby, even if there is a difference between left and right handedness, the winding configuration shown in FIG. 2 does not change. That is, even if there is a difference between right and left hand, the winding shaft 12 does not play, and a uniform and sufficiently hard bandage winding force can be obtained.

  If the heights h of the front and rear guides 13 and 14 are different, the positional relationship between the winding shaft 12, the guide 13 and the guide 14 shown in FIG. The positional relationship of the axes is different. Therefore, the difference between right and left handedness affects the winding tension force, and there is a possibility that a uniform bandage winding force cannot be obtained. According to Example 2, there is no such inconvenience, and the bandage can be wound tightly and firmly.

  Further, as a feature of the second embodiment, a handle 124 integrally formed with the take-up shaft 12 is extracted from the bearing 121, and the handle 124, the take-up mechanism 1 and the clamp 2 'are disassembled, and 1 is composed of separate parts. It can be easily carried as a set of components.

<Alternative / Modification>
As mentioned above, although the preferable Example of this invention was described, this invention is not limited to the said Example, Furthermore, various deformation | transformation and substitution can be implemented.

  For example, in Example 2, the winding mechanism 1, the clamp 2 ′, and the handle 124 having the winding shaft are configured as separate parts. According to the modified example, it is possible to further disassemble the guide 13, the guide 14, and the movable plate 11 by increasing the disassembly degree of the winding mechanism 1 and removing the nut screw 142. On the contrary, in this case, since it takes time to assemble these parts, it may be necessary to consider the workability when assembling.

  In the above embodiment, the movable plate 11 is configured to be movable along the guides 13 and 14 in accordance with the width of the bandage. However, when the width of the bandage is constant (one type of bandage), it is not necessary to match the width, so the movable plate 11 and the stays 131 and 141 are not necessary. In that case, the bearing 121 can be attached to the side plate 15 formed in the same shape as the movable plate 11 to support the winding shaft 12. Other mechanisms may be the same as those in the first and second embodiments.

  In the above-described embodiment, the arm 123, the handle 124, and the like are configured as separate members and coupled with screws or the like. However, according to an alternative, the winding shaft 12 and the handle may be integrally formed.

Moreover, the bottom plate of Examples 1 and 2 does not need to be a planar plate. The material cost can be saved by forming a slit in the bottom plate or deleting the central portion of the bottom plate, assuming that the required strength is maintained.
Further, the side plate, the bottom plate, and the clamp members are not limited to iron plates, and may be made of aluminum, reinforced plastic, or ceramics.

  The terminology used in the description of the above embodiment is an example, and there are various names and names. Those names may be considered to be the same as the constituent elements of the above-described embodiment as long as the functions and operations similar to those of the present invention are realized. For example, the side plate can be called a side panel, and can be called a fixed plate from the functional aspect. The movable plate 11 may be called a slide plate. Further, the clamp part or the clamp may be called a fixing part or a fixing tool or an attachment mechanism part of the winding mechanism.
