Description

[Detailed explanation of the idea] <Technical field of this invention> The present invention relates to a cord winding device.

<Prior Art> Some cord winding devices have a cord holder which is provided in a recessed part of a device constituting the main body of the holder so that it can freely appear and retracted, and when the cord is used, the cord holder is pulled out from the recessed part to unravel the cord.

Looking at this type of conventional device, as shown in Figures 1 and 2, the side wall surface of the cabinet is placed in the inner part of the recess 2 provided in the side surface of the cabinet 1 of the device that forms the holder body. A bearing part 3 projecting and extending into a cylindrical shape is provided, and the shaft part 5 of the cord holder 4 is supported by the bearing part 3 so as to be rotatable and reciprocally slidable, so that the cord winding part 6 protrudes and retracts from the recess part 2. I have a configuration that allows this.

However, since this conventional cord winding device does not have a locking mechanism when the cord holder is housed in the recess, there is a risk that the cord holder may rattle or pop out when in the housed state.

<Purpose of the present invention> The present invention was devised based on the above-mentioned drawbacks of the conventional device, and is a cord winding system that can reliably lock the cord holder with a simple structure when the cabinet cord holder is in the stored state. The aim is to provide the equipment.

<Configuration of the present invention> An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Figure 3 shows the cabinet (forming the holder body) of a device equipped with the cord winding device according to the present invention.
Figure 4 is a perspective configuration diagram of the main parts seen from the inside.
Figure 5 is a front view of the same part as shown in the figure, and Figure 5 is a sectional view taken along line A-A' in Figure 4;
The figure is a perspective view of the cord holder.

Referring to these figures, first, the cord holder will be explained. The cord holder 11 consists of a shaft portion 12, a cord winding portion 13 provided at the front end of the shaft portion, and a radially outward direction on the periphery of the other end of the shaft portion 12. It consists of an engaging part 14 having an engaging rib 15 formed protrudingly at its tip and extending parallel to the shaft part 12 toward the cord winding part 13, and a handle 11' on the front surface of the cord winding part 13, A cord 16 is wound around a cord winding part 13.

The holder main body, that is, the device cabinet 17, has a side wall surface 17' recessed inwardly into a cylindrical shape, and a bearing hole 20 is provided at the rear end of the cylinder.
A recess 18 having a stopper surface 19 in the center, a pair of rib receivers 21 extending in the axial direction in the shape of a groove on the outer peripheral wall of the recess 18, and a pair of rib receivers 21 extending rearward from the outer periphery of the inner end of the recess 18 on one side of the tip end. A pair of projecting edges 22 provided with abutments 23, and a pair of guide frames 24 provided on the outer peripheral wall of the recess 18 to form an insertion/removal guide groove 25 passing through the outer peripheral wall of the recess 18 in the axial direction. A pair of guide pieces 27 are provided along the outer circumferential arc surface of the recess 18 on one side edge of each notch 26 provided in the wall surface of the end portion of these guide frames 24.
and a boss 28 provided on the back surface of one of these guide pieces 27 and having a screw hole 29 along the axial direction of the recess 18 are formed as shown in the figure.

Incidentally, the tip surfaces of the projecting edges 22, 22 having the abutment 23 serve as a cam surface 22'. That is, the tip surface with the abutment 23 has an inclined surface that gradually rises from the end near the rib receiver 21 to the end having the abutment 23, forming a cam surface 22'.

Further, the insertion/removal guide groove 25 formed by the guide frame 24 is open at both front and rear ends thereof.

As described above, the cord holder 11 and the cabinet 17 of the present invention are constructed individually, and the cord holder 11 is assembled to the cabinet 11 in the following manner.

That is, first, the cord holder 11 is placed facing the front surface of the cabinet 11 with its engaging portions 14, 14 facing first, and then the engaging portions 14, 14 are
are inserted into the insertion/removal guide grooves 25, 25, and the shaft portion 12 is inserted into the recess 18, respectively.

Then, when the shaft portion 12 is inserted into the bearing hole 20 and the engaging ribs 15, 15 of the engaging portions 14, 14 are aligned with the notches 26, 26 of the guide frames 24, 24, the cord holder 11 is attached to the handle 11'. Then rotate (in the direction of arrow a in FIG. 4) each engaging rib 15,
15 corresponds to the rib receivers 21, 21, screw the stopper screw 30 into the screw hole 29 of the boss 28, and the cord holder 11 will fit into the engaging ribs 15, 1.
5 is restricted so that it cannot return to rotation in the direction of arrow b until it aligns with the notches 26, 26.

This completes the assembly of both, and in this state, the cord winding part 13 of the cord holder 11 fits into the recess 18 as shown in FIG.
The abutting surface 13' of 3 is in contact with the stopper surface 19 at the inner part of the recess 18, while the engaging parts 14, 14 are in contact with the cam surfaces 22', 22' of the projecting edges 22, 22.

<Operation of the present invention> The present invention is constructed as described above, and next, the operation of the cord holder 11 in the assembled state as described above will be explained.

FIG. 7 shows a state in which the cord holder 11 is substantially housed in the cabinet 17, and in the present invention, the coat holder 1
1 can be locked.

That is, in the state shown in FIG. 7, the cord holder 11 is in a state in which the engaging ribs 15, 15 are detached from the rib receivers 21, 21 and correspond to the rib receivers from the front. When rotated in the direction of arrow a by operating the handle 11', the engaging portions 14, 14 engage the cam surfaces 2 of the projecting edges 22, 22.
2', 22', and the result code winding section 1
The cord holder 11 is locked in the cabinet 17 with the abutting surface 13' of the cord holder 13 in close contact with the stopper surface 19 and the engaging portions 14, 14 with the cam surfaces 22', 22', respectively.

To release the cord holder 11 from this locked state, operate the handle 11' to release the cord holder 11.
Just rotate it in the direction of arrow b and return it.

In order to pull out the cord holder 11 from the stored state shown in FIG. 7, it is best to hold the handle 11' and pull the cord holder 11 in the direction of arrow c. That is, when the cord holder is pulled, the side surfaces of the projecting edges 22, 22 and the side surfaces of the guide pieces 27, 27 engage the engaging portions 14, 1.
4 is guided by the engaging ribs 15, 15.
is inserted into the rib receivers 21, 21, and the cord holder 11 has its cord winding portion 13 facing outside of the recess 18.

FIG. 8 shows this pulled-out state, and it goes without saying that the cord 16 of the cord winding section 13 can be unwound or wound in this pulled-out state.

As described above, in the present invention, the reciprocating movement of the cord holder 11 in the axial direction is guided and supported by the bearing hole 20 of the recess 18 and the rib receivers 21, 21 on the outer periphery of the recess 18, so that it is necessary to insert and remove the cord holder 11. Even if the reciprocating distance E is the same as the conventional one, the dimension h of the shaft portion 12 may be smaller than the conventional H.

<Effects of the present invention> Since the present invention is constructed as described above, when the cord holder is rotated with the cord holder housed so that the cord winding part is located in the recess, the cord holder can be rotated. This is an excellent idea that allows you to securely maintain the locked and stored state.
