Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a cable puller that pulls out and stores connection cables that connect devices. Regarding the removal/storage mechanism.

0002

[Conventional technology]

In general, a connecting cable is a cable used for the purpose of transmitting electrical signals or supplying power. It is a kind of connection device.

0003 Figure 4 is a perspective view of a vacuum cleaner to explain an example of a conventional cable drawer/storage mechanism. It is a diagram. An example of a conventional cable pull-out/storage mechanism is a cleaning system as shown in Figure 4. Pulling out the cable 23 from the main body 24 in the power supply cable for the removal machine and Applied to storage. In other words, when using this vacuum cleaner, the socket 22 Pull the cable 23 out of the main body 24 and connect it to the power terminal socket. Power is supplied to the device through the cable 23 by connecting it to the port. Also After use, the connection wire is stored in the vacuum cleaner body by the switch 21.

0004 Although the cable drawer/storage mechanism built into this vacuum cleaner is not shown in the drawing, A wheel that rotates in one direction by spring force and rewinds the cable 23, and this wheel A ratchet wheel is installed coaxially with the wheel, and this ratchet wheel rotates. The cable becomes free to rotate, and by pulling the cable 23, the cable resists the spring force. 23 is pulled out from the main body 24, and by releasing the cable, the spring force It had a structure in which the cable 23 was drawn into the main body 24.

[0005]

[Problem that the idea aims to solve]

Conventional cable drawer/storage mechanisms are built into the equipment, are not independent, and are The disadvantage is that it lacks versatility in that it cannot be used as is in other devices. . Additionally, the length of the cable could only be adjusted on the device itself. Therefore, this idea The purpose of this is to allow the length of both ends of the cable to be independently variable, so that it can be used from either side between connected devices. The cable length can be adjusted, making it a versatile cable drawer and storage that can be applied to any type of equipment. It is to provide a storage mechanism.

[0006]

[Means to solve the problem]

The cable drawer/storage mechanism of this invention has two openings from which the cable is pulled out. A casing, a rotating shaft attached to this casing, and an intermediate part of this rotating shaft. and means having a restoring force of a spring that applies rotational force to the rotating shaft, and a means on both sides of this means. The notch grooves attached to the rotating shaft are formed in opposite directions. a ratchet wheel having a portion for winding the cable, and a ratchet wheel that engages the notch groove. It has a pawl for stopping and a shaft with a pawl that is attached to the casing.

[0007]

【Example】

Next, the present invention will be explained with reference to the drawings.

[0008] Figure 1 is an external perspective view of a cable drawer/storage mechanism showing one embodiment of the present invention, and Figure 2 2 is an exploded perspective view of the cable drawer/storage mechanism of FIG. 1. FIG. This cable drawer As shown in FIGS. 1 and 2, the storage mechanism fits into bearings of the upper and lower casings 5a and 5b. The rotary shaft 6 to be loaded and the winding plate 10 of this rotary shaft 6 are mounted on both sides. ratchet wheels 7 and 17 having cutout grooves in opposite directions, and a winding plate 1. 0 and rotated by ratchet wheels 7 and 17 in opposite directions. When you hook the rubber belts 9 and 19 that give force and the belts 9 and 19, The pins 8 and 19 embedded in the ratchet wheels 7 and 17 and the rotating shaft 6 Socket 1 introduced into the hole and wrapped around by ratchet wheels 7 and 17 and 2 are attached to the cable 3, and the notch grooves of the ratchet wheels 7 and 17. A claw-equipped shaft 11 having claws 11a and 11b that can be inserted into the shaft, and one end of this claw-equipped shaft 11. It has a knob 4 attached via a housing 5a.

[0009] Figures 3(a) and (b) show the operation of the cable drawer/storage mechanism shown in Figures 1 and 2. FIG. 3 is a partial diagram shown in order of operation for explaining the operation.

0010 Next, the operation of this cable drawer/storage mechanism will be explained using FIG. 3. first, FIG. 3(a) is a diagram when the cable 3 is pulled out from the housing 5. In other words, When the ratchet wheel 7 is pulled, the pawl 11a goes over the notch groove and rotates. Turn around. The cable 3 wrapped around the shaft of the ratchet wheel 7 is pulled out. At the same time, the pin 8 fixed to the ratchet wheel 7 is released from the rubber belt 9. and wrap the belt 9 around the shaft of the winding plate 10. At this time, belt 9 It tries to return to its original length, but the notch groove of the ratchet wheel 7 is against the pawl 11a. The ratchet wheel is formed in a direction that prevents the rotation direction. 7 does not rotate in the opposite direction, but only in one direction, and the cable 3 is pulled out.

[0011] Next, when storing the cable 3 as shown in FIG. 3(b), first turn the knob 4 The pawl 11a is removed from the notch groove of the ratchet wheel 7 by turning. this As a result, the restoring force stored in the belt 9 is released, the pin 8 is pulled, and the ratchet Since the cut wheel 7 rotates in the opposite direction to when the cable 3 is extended, the cable The wheel 3 is wound around the shaft of the ratchet wheel 7. Then let go of knob 4. Then, the claw 11 of the claw shaft 11 is moved by the spring force of the lower attachment part of the claw shaft 11. a enters the notch groove of the ratchet wheel 7 again, and the cable 3 is unwound. Stop.

0012 In addition, the ratchet wheel machine of the cable drawer/storage mechanism in this example Although I have explained only one side of the structure, the two pairs can be overlapped because they can perform exactly the same operation. This makes it possible to independently vary the length of both ends of the connection line.

[0013] In the above explanation, as an example, a rubber belt is used as the power to wrap the cable. However, it is not limited to this, and a mainspring or coil spring can also be used. It is clear that the same effect can be obtained and the purpose of the present invention can be achieved by using That's it.

[0014]

[Effect of the idea]

As explained above, the present invention has two cutout grooves formed in opposite directions. A one-way rotation mechanism using a ratchet wheel is installed on the same axis, and this ratchet wheel By combining springs that power the coil in one direction and in the opposite direction, The length can be adjusted from either side, making it a versatile product that can be applied to various devices that require connection lines. This has the effect of providing a highly usable cable drawer/storage mechanism.
