Hereinafter, a safety knob 100 for a blind according to an embodiment will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a safety knob 100 for a blind according to an embodiment.

1, a safety knob 100 for a blind according to an embodiment includes a body 110, a winder 130, a switch 150, and a winding roll 170. As shown in FIG.

It is preferable that the body 110 has a size that the user can grasp with one hand. The body 110 may be configured in various forms and as one example the body 110 may be configured to include a first wall portion 112, a second wall portion 114, and a connection portion 116.

A space is formed between the first wall portion 112 and the second wall portion 114 so that the winding roll 170 can be provided. That is, the first wall portion 112 and the second wall portion 114 support one side and the other side in the width direction of the wind-up roll 170, respectively.

The connection portion 116 connects the upper portion of the first wall portion 112 and the upper portion of the second wall portion 114. The connection portion 116 preferably has a predetermined volume so that the user can easily grip the connection portion 116. A through hole 116a is formed in the connection portion 116. [

The winder 130 is provided on the body 110 and functions to rotate the winding roll 170. [ When the body 110 is constituted by the first wall portion 112, the second wall portion 114 and the connecting portion 116, the winder 130 may be attached to either the first wall portion 112 or the second wall portion 114 One or both of the first wall portion 112 and the second wall portion 114 may be provided.

2 is a schematic view showing the structure of the winder 130. As shown in Fig.

Referring to FIG. 2, the winder 130 may have a structure similar to the interior of the automatic tape measure. As an example, the winder 130 may include a gear 134 rotatably coupled to the body 110, A helical spring 132 provided between the gear 134 and the rotary shaft 174 of the winding rule 170 and a detent 136 for restricting the gear 134. [ The structure of the winder 130 is not limited to the shape shown in the drawings, and it may be replaced with a product having a different driving mechanism as long as it is a typical engineer.

The switch 150 is provided in the body 110 and functions to control the operation of the winder 130. For example, when the body 110 is composed of the first wall portion 112, the second wall portion 114, and the connection portion 116, the switch 150 may be provided in the connection portion 116, The switch 150 controls the position (movement) of the detent 136 when the detent 136 is composed of the spiral spring 132, the gear 134 and the detent 136. [

The winding roll 170 has a function of winding the blind operation string BL. A rotating shaft 174 may be formed at an end of the winding roll 170 and a pair of rotating shafts 174 may be formed at a position where the body 110 is connected to the first wall portion 112, And is inserted into the first wall portion 112 and the second wall portion 114, respectively.

On the outer circumferential surface of the winding roll 170, a groove 172 for accommodating the end portion of the blind operation string BL is formed. In consideration of the movement of the blind operation string BL, the groove 172 of the winding roll 170 is preferably formed in a U-shape.

Fig. 3 is a view showing various modifications of the winding roll 170. Fig.

Referring to FIG. 3 (b), the safety handle 100 for a blind according to the embodiment may further include a safety hook 190.

The safety ring 190 is made of an elastic material and is coupled to the winding roll 170 so that the blind operation string BL received in the groove 172 does not come off and the outer peripheral surface of the winding roll 170 is divided into two regions So that when the blind operation string BL is wound around the winding roll 170, the blind operation string BL can be wound in a uniform thickness without being shifted to one side in the width direction.

Referring to Fig. 3 (c), a person skilled in the art will be able to deform the groove 172 of the winding roll 170 into a hook shape.

4 is a use example of the safety knob 100 for a blind according to the embodiment.

4A, a user inserts an end portion of a blind manipulation strap BL into a through hole 116a formed in a connection portion 116, and then hooks the end portion of the blind manipulation strap BL in a groove 172 formed in the swing roll 170 , The safety knob 100 for a blind according to the embodiment can be quickly installed in the blind.

Referring to FIG. 4 (b), in a state where the safety knob 100 for a blind according to the embodiment is installed on the blind, the user pulls one side of the blind operation strap BL as before to unfold or collapse the blind have.

4C, when the user presses the switch 150 after the operation of the blind is completed, the winder 130 rotates the wind-up roll 170 to wind the blind operation string BL . In this way, the user can reduce the length of the blind operation string BL and position the end of the blind operation string BL at a height inaccessible to the infant.

The safety knob 100 for a blind according to the embodiment can be easily applied (mounted) to a blind having a blind operation strap BL in a general form. In addition, the user of the safety knob 100 for a blind according to the embodiment can press the switch 150 to reduce the length of the blind operation string BL in a simple manner.

In addition, the manufacturing cost of the safety knob 100 for blinds according to the embodiment is low due to its structure, and it is less likely to be broken even if it is used for a long period of time.

The safety handle 100 for a blind according to the embodiment described above can be variously modified by a person having ordinary skill in the art without departing from the technical idea of the invention.

Accordingly, the scope of rights of the technology disclosed herein should be broadly interpreted based on the technical idea contained in the description of the invention and the drawings.
