Description

  The present invention relates to a structure for reducing the deformation and entanglement of a curl generated in a curl molding part of a curl cord used for home appliances, etc., and further, a safety rope used for preventing a fall of a portable article by connecting the portable article and a carrier Further, the present invention relates to a structure for reducing the deformation and entanglement of the curl generated in the curl molding part that can be applied to the curl molding part such as a curl rope sold under the name of a rope for preventing fall.

  Conventionally, most of the curl cords are used for home appliances. For example, fixed telephones are used for cords arranged between a main body and a handset (see, for example, Patent Document 1).

  However, as shown in FIG. 7A, the telephone used daily is a part of the curl cord 9 arranged between the telephone body 7 and the handset 8 as shown in FIG. Frequently deformed (deformed portion 10).

  Further, when the handset 8 is returned to the telephone body 7, the curl cord 9 may be twisted depending on how the handset 8 is returned, and the curled portion may be entangled (entangled portion 11) as shown in FIG. Since the curl portion has been stretched in what has been used for many years, there is a large gap between the curls, and the curl portion is more easily entangled.

  For the person who uses the telephone, the curl deformation (deformed part 10) and the entanglement (entangled part 11) as shown in FIGS. 7 and 8 generated in the curl cord are very unsightly and difficult to use. So, sometimes I fixed these things back to their original state.

  Also, when the deformation or entanglement of the curl is corrected and returned to the original state, it can be returned to the original state relatively easily at the initial stage, but sometimes the deformation or entanglement is progressing. In this case, it took time and effort to restore the original state, which was very troublesome.

  The object of the present invention is to reduce curl deformation and entanglement that occur in the curled portion of the curl cord by normal use, and even when the deformation or entanglement occurs, An object of the present invention is to provide a structure for reducing the deformation and entanglement of a curl generated in a curl molding portion of a curl cord that can be easily repaired and returned to its original state.

  In order to solve the above-described problems, the gist of the structure for reducing curl deformation and entanglement generated in the curl forming portion of the curl cord according to the present invention is that of a cord having a portion formed in a curl shape, that is, a spiral shape. A predetermined follower member is provided at least in the curl space of the curl molding portion so as to follow the movement of the cord, and an urging force can be accumulated in the follower member as the cord movement is followed. It is characterized by using things.

  The present invention will be described in more detail. A curl cord used for home appliances is configured by providing straight portions having a considerable length at both ends of a curl portion formed with a predetermined curvature, if necessary. Connection members such as a modular jack and a plug / plug socket for connecting to a predetermined device are provided at both free ends of the linear portion.

  The follower member provided at least in the curl of the curl molding portion of the curl cord may be any member that can follow the movement of the curl cord, such as expansion and contraction, bending, etc. Depending on the properties (materials such as synthetic resin materials) are suitable, a structure configured to be able to move such as expansion and contraction and bending may be used.

  In addition, as a specific example when the follower member is formed of a material property, a flexible and elastic single elastic wire made of a natural rubber or a synthetic rubber (elastomer / silicone) material, A plurality of bundles, for example, a predetermined stretch line such as a structure in which an appropriate number is arranged or a structure in which an appropriate number is twisted (twisted wire), or a flexible and elastic stretch tube is used. It is also possible to select appropriately according to the application form of the curl cord.

  In addition, the longitudinal cross-sectional shape of the follow-up member is usually a circle substantially matching the cross-sectional space shape inside the curl, but is not limited to this, and the range in which the function of the follow-up member can be secured. However, other cross-sectional shapes may be used in consideration of design.

  Further, the follower member may be configured using a flexible and elastic plate-like body, and this plate-like body is used singularly or plurally according to the application form of the curl cord. The tracking member's longitudinal cross-sectional shape and the spatial cross-sectional shape of the interior of the curl are approximately equal to each other, with the width dimension of the tracking member appropriately changed in the direction of the space inside the curl corresponding to the spatial cross-sectional shape. You may make it fit.

  The plate-like body is generally a plate-like body using a plate-like single member that is advantageous in terms of cost. However, a plurality of single members having a predetermined shape are arranged in parallel. In some cases, a material formed in a shape is used.

  In addition, the follow-up member may be constituted by a flexible and elastic stretchable fabric member, for example, a fine net, etc., but depending on the application form of the curl cord, an external member may be caught from the eye of the net. Sometimes it is necessary to avoid it.

  Further, when the follower member is formed of a structure configured to be able to move such as expansion and contraction or bending, it may be configured by a coil spring, for example. In some cases, it may be necessary to prevent the member from getting caught.

  As a specific example for enabling the above-described follower member to follow the movement of the curl cord, such as expansion and contraction or bending, both ends of the follower member are respectively connected to the free ends of both linear portions of the curl cord. It may be connected to the connecting member provided in the part, or may be connected to both linear parts and both bases of the curl molding part, and this connection is also possible directly or indirectly via a member that can be used for connection. Just connect.

  When the curl-molded portion is at least at the initial position, it is desirable that the follower member can be self-returned to a state close to the stable state at the initial position by the biasing force.

  In addition, the follower member provided in the curl inner space is suitable for the specification of the curl cord (for example, the strength of the self-returning force of the curl molding part) (for example, the thickness and the strength of the self-returning force). You can do it.

  Further, a part or all of the follower member may be provided in the curl inside in a state of being housed in a flexible and elastic cover. For example, a part of the follower member located in the curl inside is housed in the cover. You may make it do.

The range of the curl cord in the curl deformation and entanglement reducing structure generated in the curl molding portion of the curl cord of the present invention includes not only the electric wire but also the portable article and the portable person to prevent the portable article from falling. Equipment for work sold under the names of safety ropes and fall prevention ropes used for sports, equipment for outdoor activities such as fishing and mountain climbing, equipment for indoor activities such as indoor climbing, etc. .

  According to the structure capable of reducing the deformation and entanglement of the curl generated in the curled portion of the curl cord of the present invention, even when there is an indication that the curled portion of the curled cord is deformed, the portion formed in a curled shape, that is, a spiral shape Since the self-returning force generated in the follower member provided in at least the curl inner space of the curl molding portion of the cord having the curb suppresses the deformation, the deformation generated in the curled portion of the curl cord can be greatly reduced.

  Even if the curling part is deformed beyond the restraining force of the follower member, the self-recovery force generated in the follower member becomes the assisting force for repair, so the curl deformation can be easily corrected and the curl cord Can be quickly returned to the normal curl state.

  Even when the curled portions of the cord are entangled due to the curled cord being twisted, the following member provided in the curled space prevents the cord from entering the curled space. Can be greatly reduced.

Hereinafter, a structure for reducing deformation and entanglement of a curl generated in a curl molding portion of a curl cord according to the present invention will be described in detail based on a specific example shown in the accompanying drawings.
The attached drawings will be described with an example of a curl cord disposed on a fixed telephone as a home appliance.

As shown in FIG. 1, the curl cord using the structure of the present invention passes through the curl inner space 2a (see FIG. 3) in the curl molding portion 2 of the cord 1 as the curl body, and serves as a follower member. A flexible rope 3 made of silicone rubber or the like is provided.
Reference numeral 4 in the drawing is a modular jack for connection for connecting the cord 1 to a predetermined device.

  Then, both ends of the flexible rope 3 are connected (fixed) to both bases of the curl molding portion 2 of the cord 1 via the connecting members 3a so that the flexible rope 3 can move following the cord 1 (see FIG. 3). )is doing.

  Further, as shown in FIG. 2, the flexible rope 3 shown in the present embodiment is an example of the flexible rope 3 (thin diameter) having a cross-sectional diameter smaller than the space diameter of the curl inner space 2a in the curl molding portion 2. Although explained, depending on the specifications of the curl cord (for example, the strength of the self-returning force of the curl molding part or the applied article), a large-diameter flexible rope (not shown) having a large cross-sectional diameter may be used. The outer peripheral surface of the flexible rope can be in contact with or substantially in contact with the cord 1 surface on the side of the curl inner space 2a (not shown), and a plate-shaped flexible rope as shown in FIG. 6A is a flexible rope 3b having a substantially square cross section made of a single member, and FIG. 6B is a flexible rope 3c having a plurality of single members having a substantially circular cross section, for example. Which may cover the periphery of a flexible member Flip.

  The operation of the curl deformation and entanglement reducing structure generated in the curl forming portion of the curl cord according to the present invention configured as described above will be described below.

  As shown in FIG. 4, when the cord 1 as the curled cord body is twisted in the direction of arrow B in the figure, the flexible rope 3 provided in the curl inner space 2a together with the cord 1 is also twisted in the direction of arrow B in the figure. It is.

  When the flexible rope 3 is twisted, a return force is generated in the flexible rope 3 so as to return to the original state, and this return force, that is, the rotational force generated in the direction of arrow C in the figure, causes the twist proceeding to the cord 1. It suppresses and prevents the deformation of the cord 1.

  Even if the curl deformation as shown in FIG. 7 (b) occurs in the cord 1 exceeding the restraining force of the flexible rope 3, the self-returning force (in FIG. The rotational force generated in the direction of arrow C) becomes an assist force for repair, and the deformation of the curl can be easily corrected and the cord 1 can be quickly returned to the original normal curled state.

  FIG. 5 shows an example of a telephone using this curl cord. The curl cord, that is, the cord 1 arranged between the telephone main body 5 and the handset 6 is a flexible rope provided in the curl inner space 2a. Since the deformation to be generated in the cord 1 is suppressed by 3, the cord 1 (curl cord) can be maintained for a long time without deformation as shown in FIG.

  Also, as shown in FIG. 5B, even when the curl cord (code 1) intersects, the curl in the curl inner space 2a causes the two curls to cross each other between the curling counterparts, that is, the curl inner space 2a. If the curls of both sides are entangled, the entanglement can be eliminated by picking up the handset 6, and the entanglement of the curl cord (code 1) can be eliminated. Can be used normally.

  In particular, since the curled portion has been extended for those that have been used for many years (not shown), when the curled cord (code 1) intersects as shown in FIG. Both of the curls are easy to penetrate deeply into the inter-curl inter-curl space, that is, the curl inner space 2a. It is possible to prevent a deep entry into the inner space 2a.
