Description

Mask hanging-band adjuster using elastic film

The present invention not only easily adjusts the hanger band of the mask using an elastic film, but also maintains the fixed state of the hanger band when pulling the hanger band after adjusting the length. It is about.

In the technique of the mask band adjusting mechanism of the mask, a groove and a guide handle are formed at the center, and the folding parts are provided at both sides to protrude the hook band toward the guide handle to adjust the length, and when the hook band is pulled, the hook is hooked by the folding part. 'Hanging band adjustment structure of the dust mask' to limit the movement of the band (Korean Utility Model Publication No. 20-0321107) has been disclosed.

However, the above technique is supported by the end of the end member of which the tension band of the hook band is simply supported, which brings about natural release of tension due to facial movements such as long time wearing or conversation of the wearer, or the tension of the hook band. Since the upper and lower parts are always made at the same time, there is a hassle in adjusting the tension and inconvenience of wearing and releasing it because the hook band has to be loosened or repeated again when the upper and lower parts are selectively adjusted.

As a technique to solve this problem, 'disposable dust mask having a fluid tight wing by double bend line' (Korean Registered Utility Model Publication No. 20-0335486) has been published.

The above technique is to cut the upper and lower sides of the adjustment sphere to form an elastic piece having a working projection on one side, and to form a release prevention clip on the upper and lower ends, the locking groove and the locking projection formed on one end of the elastic piece and the control opening And, the upper and lower portions of the resilient piece is formed, and the groove is formed on the front and rear of the resilient piece hanger band is configured to be inserted bent along the groove and the space.

The above technique has the advantage that the length of the hanger band can be adjusted by pulling the hanger band, but if the structure is complicated and difficult to manufacture, structures such as elastic pieces, locking protrusions and locking grooves are not manufactured as designed during injection molding. The hook band is fixed by the coupling force between the locking protrusion and the locking groove, and the fixing and length adjustment of the hook band is cumbersome and inconvenient because the elastic band must be coupled and separated during the connection and adjustment of the hook band. There is a problem that the hanger band is pulled out of the adjuster because the engaging protrusion and the locking groove are separated from each other.

As a technique to solve this problem, 'mask hanger band adjusting device' (Korean Registered Utility Model Publication No. 20-0348888) has been disclosed.

The above technique is characterized in that the opening is formed in the direction facing each other while alternating with each other in the longitudinal direction of the adjusting body main body is characterized by consisting of a first support piece and a second support piece for supporting the hanger band.

Although the above-described technology solves many of the problems of the prior arts, after manufacturing the control unit and connecting the control unit and the mask main body, the hanger band should be completely installed by hand, and the first support piece should have the second. There was a problem that the worker's work is inconvenient and difficult to connect to the support piece, bending the hook band back to the first support piece.

In addition, the product is made of a synthetic resin material that is injection-molded, when the actual band is pulled after adjusting the length, the protruding hanger band flows to adjust the length, the ability to adjust the length is significantly reduced There was this.

Hanger band adjusting device of the mask using the elastic film of the present invention is to solve the problems caused in the prior art as described above, to manufacture the control body of the elastic polyester film material used as a material such as OHP film, length When the hook band is pulled while the hook band protrudes toward the extension incision during adjustment, the flow of the protruding portion is limited by the elastic restoring force of the film material generated from the extension incision, and the hook having the pointed shape is secondary. Since the flow of the hanger band is limited by the other side of the band insertion hole, once the length is adjusted, the fluidity of the hanger band is extremely lowered by pulling the hanger band, thereby providing a hanger band adjusting device having a small change in the length of the hanger band.

In addition, since only a simple cutting operation is made on the surface of a flat elastic film, it is intended to provide a hanger band control that can exhibit much simpler and superior performance than an injection molded product.

In addition, when the hanger band is first installed in the manufactured hanger band adjusting device, the control body is linearly connected to the upper vertical incision, the hook band insertion hole, the expansion incision, and the lower vertical incision by simply pressing in one direction between the extension incisions. The hook band can be easily installed in the hook band adjustment because the band is pushed to one side in the opposite direction between the upper and lower incisions while the hook band is pushed into this gap. The goal is to provide a hangband control that simplifies the entire manufacturing process and reduces manufacturing time.

Hanging band adjusting device of the mask using the elastic film of the present invention is made of an elastic polyester film material, in order to solve the above problems, the control body main body is fastened to one side of the mask body; An upper vertical incision formed by cutting vertically downward from an upper end of the main body; A lower vertical incision formed by cutting vertically upward from a lower end of the main body; One side is connected to the upper vertical incision and the lower vertical incision, respectively, the other side has a shape protruding to the opposite side of the mask body, the other end has two hook band insertion hole having a pointed shape; Located between two hanger band insertion hole, the upper and the lower end of the expansion section consisting of an upper extension incision and lower extension incision in the form of an arc-shaped extended to the opposite side of the mask body; Consisting of the upper incision and the lower incision connecting the incision linearly incision.

At this time, the hook band insertion hole is characterized in that formed in the oval formed long side inner diameter.

In addition, the hook band insertion hole is characterized in that the end of the opposite side of the mask body is located closer to the mask body side than one end of the expansion cutout.

According to the present invention, when the control body is manufactured from an elastic polyester film material used as a material such as an OHP film, and the band is pulled in a state where the band is protruded toward the extension incision during the length adjustment, the extension band is firstly expanded. The flow of the protruding part is limited by the elastic restoring force of the film material generated in the part, and the flow of the hook band is restricted by the other side of the hook band insertion hole having a second pointed shape. By pulling, the fluidity of the hanger band is extremely low, thereby providing a hanger band adjustment device with less change in the length of the hanger band.

In addition, since only a simple cutting operation is made on the surface of the flat elastic film, there is provided a hanger band adjusting tool which can exhibit much simpler and superior performance as compared to an injection molded product.

In addition, when the hanger band is first installed in the manufactured hanger band adjusting device, the control body is linearly connected to the upper vertical incision, the hook band insertion hole, the expansion incision, and the lower vertical incision by simply pressing in one direction between the extension incisions. The hook band can be easily installed in the hook band adjustment because the band is pushed to one side in the opposite direction between the upper and lower incisions while the hook band is pushed into this gap. Hangband controls are provided to simplify the entire manufacturing process and reduce manufacturing time.
