Inside the rotating reel, a bent portion and one end thereof are axially supported by an inner peripheral portion forming the rotating reel and connected to each other by a link. A lever, an auxiliary lever, and a fixed body are provided, and the lever has an operation end that is operated through an operation opening at one end and a connecting end that is shorter than the operating end at the other end. The other end of the auxiliary lever is fitted into the connection recess of the fixed body, and the fixed body projects outside the rotating reel through the fixed opening by the operation of the operating end of the lever, and the hollow portion constituting surface of the core tube of the winding material. Press firmly Winding material fixing mechanism that relates reels, wherein a provided.

Embodiments of the present invention will be described in detail below with reference to the drawings, but the present invention is not limited to the following embodiments.

2A and 2B show a longitudinal section and a front structure of the rotating reel,

(4) and the inner core portion (5) are continuously and integrally formed in a triple structure. Then, in the space (6) between the inner peripheral portion (4) and the inner core portion (5), the rotary reel mounting cylinder portion (8) integrally mounted on the rotary reel support body (8) is fitted, and The rotary reel (1) is rotatably mounted via two bearings (9) and (10). The rotating reel support (7) has a rotating reel
An opening (11) is provided in a portion of (1) facing the inner core portion (5), and a sprocket (12) attached to the opposite surface of the rotary reel support (7) is provided through the opening (11). It is connected to the inner core portion (5). That is, the sprocket (12) receives the power from the driving body by the chain and rotates, and the rotating reel (1) also rotates.

The end face of the rotating reel (1) opposite to the side where the guide plate (2) is present is open to form an operation opening (13), and a fixed opening (14) is provided on the outer peripheral portion (3) of the rotating reel (1). Longer in the axial direction of 1), the outer periphery
(3) is provided with one end cut away. The mounting member (16) of the lever (15) is mounted at a position substantially corresponding to the fixed opening (14) of the inner peripheral part (4), and the inner peripheral part (4) of the mounting member (16) One end projecting laterally serves as a shaft support (17) of the lever (15). This shaft support (1
The bent portion (18) is pivotally supported on 7) and the lever (15) is attached. One end of the lever (15) that is located longer than the bent portion (18) serves as the operating end (19) of the lever (15), and the other end that is located short is rotatable with the fixed body (20). It becomes the connecting end (21) of. (22) is a link, which is the bent end (18) of the lever (15) and the connecting end.
One end is pivotally supported in the part between (21) and the other end is auxiliary lever (23)
Is pivotally supported in the middle part of. The auxiliary lever (23) is
It is located in parallel with the part between the bent part (18) and the connecting end (21) of 5), and one end is fixed to the fixed body (20) and the other end is attached (16). Is supported in the back.

The connection between the fixed body (20) and the lever (15) and the auxiliary lever (23) is such that the lower surface of the fixed body (20) is provided with a connection recess (24) in the shape of a groove, and inside the connection recess (24). To each lever (15) (2
A screw (25) that fits the connecting end of 3) and is inserted horizontally
And fixed by nuts (26). (27) is a winding material, and the core tube (28) is located in the innermost part, and the core tube ((28) is made of a deformable material such as vinyl chloride or cardboard.

A winding material fixing mechanism is configured by the lever (15), the auxiliary lever (23), the link (22), the fixed body (20), the shaft support (17), and the shaft support of the auxiliary lever (23). Is. In this embodiment, the auxiliary lever (23), the link (22), and the shaft supporting portion of the auxiliary lever are also included as the elements constituting the winding material fixing mechanism, but the lever (15) and the fixed body (20 It is also possible to construct the winding material fixing mechanism by only the () and the shaft support portion (17). In the above embodiment, the fixed body (2
It is possible to use a long fixed body (20) capable of stably fixing the winding material as a structure for supporting (0) at two points.

As the fixed body (20), one having hardness and rigidity is used, and a metal material is generally used. Each lever and link also use a metal material.

The operation of the winding material fixing mechanism will be described below.

The pivotal support of the lever (15) to the pivotal support (17) is not performed in a free state, but is performed in a considerably pressed state. When not locked, the lever (15) operating end (1
9) is located in the operation opening (13), and the fixed body (20) is fixed opening (1
The winding material (27) does not project upward from 4) and is in a state of being inserted and locked in the rotating reel (1) itself. In this state, when the operating end (19) of the lever (15) is pulled forward in the direction of arrow A against the pressure contact strength of the shaft support, the lever (15) moves the shaft support (1).
It rotates about 7) and its connecting end (21) also moves along the fixed upper part (20) in a curved shape to the upper rear part as shown by arrow B. With the movement of the lever (15), the link (22) and the auxiliary lever (23) also move to move the fixed body (20) similarly. The upper surface of the fixed body (20) moves to the upper part and the fixed opening (1
4) When it comes to the position almost flush with the surface (state of Fig. 2),
Touch the inner surface of the core tube (28) of 7), that is, the surface of the wound material forming the hollow portion. When the lever (15) is further pulled, the fixed body (20) raises the winding material (27), and the outer peripheral portion (3) located on the opposite side provided in the fixed opening (14) of the rotating reel (1). The inner surface on the opposite side of the core tube (28) is still in contact with the peripheral surface portion of the. When pulling the lever (15) further, the fixed body (20) is the core tube (28).
Is deformed, and the core tube (28) is made to bite. This state is the fixed state of the winding material (27), and this state is the shaft support (1
It is maintained by the pressure contact strength at 7) and the bite of the fixed body (20) in the core tube (28). The winding material (27) also deforms slightly due to the deformation of the core tube (28), but the rotating reel (1)
There is no hindrance with regard to winding and sending.

Since the present invention is configured as described above, the winding material can be fixed and released with one touch by operating the lever, which is extremely efficient. Further, since it has a simple structure, it can be provided at a low cost.
