Abstract

The present invention relates to a headphone speaker cover which can attach or detach a sanitary cover easily and conveniently through buckling effect and inclined plane friction and elasticity principle, by: combining an one-directional Velcro comprising needle-shaped hook needles using principle of moment of force and inclined plane friction and principle of elasticity, in order to cover the sanitary cover (102, fiber cover, sponge cover etc) on a body cover (001) of the headphone speaker, on the speaker body cover (001), or to an elastic band (003) frame of a fixed shape attached or detached to or from the cover; making an inner plane attachment part (008, loop) be smoothly slid through a first sliding curve (12) of the hook needle by pushing the sanitary cover; and along the opposite direction thereto, making the Velcro be hooked to a barb probe of the hook needle like a barb of a fish hook. Because the hook needle has a needle shape structure, a material of the loop formed in the sanitary cover geared to the hook needle may be a porous paper fiber, sponge and all sorts of the fabric itself. Therefore, the variety of choice is too large to be compared with the Velcro. Thus, the headphone speaker cover of the present invention has the effect of being able to assure all of convenience of attachment and detachment and wearing safety as reducing production costs of the sanitary cover.

Description

[0001] The present invention relates to a headphone speaker cover, and more particularly, to a headphone speaker cover and a flexible speaker band cover which are combined with a unidirectional speaker,

The present invention is characterized in that a unidirectional tapper constituted by "hook needles" using the principle of moment of force and the principle of bevel friction and elasticity is mounted on a speaker main body cover (001) 003), and a sanitary cover having a certain loop formed on the inner surface thereof can be attached and detached easily and conveniently with a buckling effect and an oblique friction and elasticity principle.

With respect to fasteners similar to the unidirectional attachment and detachment scheme contemplated by the present invention, various types of hook materials such as the inverted J-shape, T-shape and mushroom shape are used according to the following citation 1: It introduces VELCRO HTH-840 and various loop materials as a 100% unidirectional molded hook material including type hook.

Reference 2 discloses loop and arcuate fiber fabrics woven with a nonwoven textile plastic resin called " spun bonded " as a loop member.

[0004] In relation to the one-way attachment / detachment system of the present invention, [Patent Document 3] discloses a fixing protrusion formed so as to project obliquely upward from the opening portion so as to generate a one- corn type) to facilitate the wearing of the wig on the scalp in a non-binding manner.

The hair clip for fixing a wig is capable of releasing or releasing hair by buckling effect of several legs in relation to a hair clip which is similar in shape and working principle to the "hook needle" of the present invention .

On the other hand, Shape Memory Alloy or shape memory polymer applied to the "hook needles " of the present invention is introduced in Literature 5 to 7 below.

Reference [5] discloses a detailed description of the shape memory polymer specifically. The difference in mechanism between the shape memory polymer and the shape memory alloy is specifically described.

[Patent Document 6] discloses that a TPU (thermoplastic polyurethane) material having high elasticity has both properties of plastic and rubber, thereby providing excellent elastic restoring force and providing a smooth texture. In addition, the Ni-Ti (Nitinol) shape memory alloy is not only excellent in corrosion resistance, but also can be coated with a TPU material.

In reference [7], it is explained that shape memory alloy springs such as Ti-Ni do not permanently change the relaxed shape of the spring even if it is bent a lot. It also introduces stress-strain characteristics when plastic materials are applied.

In the hook-and-loop fastener closely related to the present invention, the structure of the inverted J-type Velcro, the principle of its operation and the detachment force And the strength of the force of the.

Velcro (a conventional squeaker, VELCRO: trade name), as is well known, is a very small hook that is akin to aka spike needles, As shown in Fig. 1 (J, Ja), and is composed of a fiber loop member which is lined up and aligned at regular intervals and engaged with the fabric.

The bent end portion of the J-shaped hook (hook) is formed to be very rough and sharp as shown in Fig. 1 (J, Ja) so as to be easily caught by the napkin. It is configured to easily hang on the thread strand.

The direction of the bent hooks is formed symmetrically or alternately in a line at a constant inclination angle with respect to each line. There is also a Velcro in which the direction of the bent hooks is formed in such a way that each line is lined up in the opposite direction to each other.

Therefore, regardless of the direction in which the fabric with the fluff is formed, the end of the fabric is made compact so as to be easily caught on the fluff.

Even if the rounded surface of the hook is subjected to fluff, the end of the hook is easily caught on the fluff. Once the hook needles catch on the fluff, they will not fall off well.

Therefore, in order to attach an object having a lint to the velcro, a cloth (fiber loop) must be pressed against the upper surface of the lugs. When the lint is applied to the side of the lugs, the lint It can not be attached properly.

In addition, the width (width) of the rounded portion of the hook is formed to be relatively shorter than the height so as to easily enter into the gap of the fiber loop fluff, and once the fiber enters the gap of the fluff, It becomes possible.

In this way, each of the hooks acts on a clearance of the fiber loop web (fluff) to hook the hooked claws to the thread of the fiber and has a certain binding force or a force of disassociation force .

That is, when a certain amount of force is applied to the hooks of the fiber loops and pulled in a certain direction, the hooks have a constant binding force until the bent hooks are completely extended. At this time, As shown in Fig.

Therefore, if the strength of the detachment force (binding force) of the conventional velcro is assumed to be constant in terms of the strength of the binding force of each hook that acts on the nap (web), the greater the number of hooks, The larger the area of the Velcro, the more it increases directly. This means that the size of the Velcro area means the strength of the attachment and detachment force.

Therefore, when the hooks are made to work together in a certain group, it is possible to exert a very strong attachment and detachment force. In this respect, in the past, Velcro has a great advantage that nobody can deny.

However, this strong attachment / detachment means that the force of the separation force particularly at the time of detachment is also very strong. This is because, when attaching a Velcro to an object and detaching it from time to time It may be a disadvantage which is rather disadvantageous.

Consequently, since the strength of the detachment force is simultaneously increased or decreased in proportion to the area size of the velcro, the force of the detachment force can not be structurally reduced.

Therefore, if the size of the Velcro is increased, the force of the attaching / detaching force naturally also increases at the same time.

Therefore, in order to minimize the force of the release force, the size of the Velcro area should be as small as possible.

Based on the above-mentioned theory, according to the contents of Document 8, which was filed by the present applicant, in order to easily attach and detach the sanitary cover in the constitution of the flexible elastic band used for the headphone speaker hygienic cover, At least three or more uniformly formed squeezers (having a size of about 0.4 × 0.6 cm and a number of hook needles of about 5 × 3, about 4 × 3, and about 3 × 3) So that it is possible to reduce the force at the time of attaching and detaching.

In the above-described [Document 8], when a flexible cover with a flexible hook is attached to the headphone speaker and the fiber cover having the detachable portion (loop) is attached, the hook is pushed side by side with the hook- Likewise, since the loops in the fiber cover are caught by the hook ends of the rough and sharp hooks (Velcro) and can not be attached properly, it is troublesome and troublesome to lift the cover ends up and attach them to various small hooks An inconvenient problem arises.

In addition, since the male hooks of the Velcro have to be made only of a female type fiber loop that meets their suitability, the selection of the material is extremely limited.

That is, when a loop such as a paper towel, a porous sponge or the like as intended by the present invention is directly used as a female loop to be attached to and detached from the hook, there is an extremely limited aspect in which the hook of the Velcro does not fully exhibit its function .

On the other hand, when a plurality of hook fasteners such as a tongue are formed on the rim of the elastic band, the band and the sanitary cover must be combined with the male and female tongues together. In particular, in the case of forming the tongue on the sanitary cover formed of disposable paper, There may be a disadvantage that the production cost is relatively high.

In addition, since it is necessary to strongly press several points of the band at the time of attaching, it may cause the distortion of the speaker body as well as the failure thereof. In addition, since the force of the adhesive force is large when it is detached, it is inconvenient that the band is detached together.

Incidentally, the conical-shaped structure mentioned in [Document 3] can not be bound to the fiber loops of the present invention because the ends are relatively thick and round, Binding) method, there is a problem in the binding force.

Therefore, in the present invention, in order to easily attach and detach the sanitary cover (the fiber cover, the covering cover) directly on the headphone speaker main body cover by the buckling effect and the principle of the beveled surface friction and elasticity, Together.

First, a support 11 having a round first curved surface 12, an inflection point extension 13 bent and deformed by a constant external force together with the support, And a needle 16 having a second sliding surface 15 and a barb tip 14,

The barbed tip is protruded and formed as a conical shape curved outwardly on the horizontal tangent of the extension, and the height and the overall length of the barrel are formed as short as possible according to the principle of the force moment, Needle hooks made of memory (alloy or plastic)

On a side edge of a headphone speaker main body cover 001 or on a side edge of a certain elastic band (003)

The first slip curved face 12 is arranged in a row at a predetermined interval in a row perpendicular to the longitudinal direction of each frame so as to face the sound output port side of the speaker.

Secondly, in order to detach and attach the rear portion of the speaker body 006 to a predetermined side portion of the elastic band,

It is also possible to add a supplementary band 012 formed with attachment and detachment means (such as a tongue, a hook, a hook, a button, a unidirectional tap).

Third, an air-permeable hygienic cover (fiber cover or cover) formed by forming a detachable part (008, loop) in the form of a rim on the inner surface of the lid to engage with the hook needles is attached to the speaker main body cover (001) It is detachable on the band.

When the sanitary cover is directly pushed on the speaker main body cover 001 with the unidirectional tapper according to the present invention, the inner surface fluff of the sanitary cover slides on the first slip curved surface 12 of the hook needle And in the opposite direction, the barb stitches 14 (needle needles) are easily attached by the buckling effect while being caught in the gap of the fluff like a barb of a fishing needle.

In addition, when the sanitary cover itself is lifted up using the elasticity of the sanitary cover itself, the sanitary cover can be easily detached and attached more easily than before by removing the sanitary cover with the principle of friction and elasticity.

Since the hook needles of the unidirectional tapper have a needle-like structure, the loop material to be engaged therewith is not limited to a napple-shaped fabric having a porous gap, a paper fiber, a porous sponge, All kinds of various materials can be used.

Therefore, the width of the choice of loop material is so wide that it is incomparable with Velcro. Therefore, even if the production cost of the sanitary cover is small, the convenience of detachment / attachment and the safety of wearing can be secured.

A more detailed description related to the unidirectional tapper according to the present invention will be described with reference to the accompanying drawings. Quot; 1020140060738 "

1 (A), the configuration of the hook needle 1 (17) according to the present invention is similar to that of the hook needle 1 (17) according to the present invention, except that it has a column 11 having a round first sliding curved surface 12, And a needle 16 having a second sliding curved surface 15 and a barbed needle 14 (needle tip) which are extended in a round shape.

The barbed tip is protruded in a circular conical shape outwardly on the horizontal tangent of the extension, and the height and the overall length of the barrel are made as short as possible in accordance with the principle of force moment, .

Further, as shown in FIG. 1 (B), the extension needle and the second slip curved surface may be formed as a hook needle 2 (18) with a rounded jaw additionally formed.

In order to constitute the unidirectional tapping with the hooks 1 and 2 thus configured, first, a certain mold (mold) is produced, and elastic plastic such as polyester or a material such as a shape memory alloy 1 and 2 (H, G) and 4 (Ca and Cb), the hook needles 1 and 2 are arranged on the molding substrate 10 in a transverse direction ) To form an integral body.

1 (Bd, Be), the unidirectional tapper thus formed is further placed on a further substrate 30 (or fabric) formed of a material such as polyester or silicone synthetic plastic, So that the attaching / detaching space 20 is formed.

1 (C) to (C) and FIG. 1 (E to Ec), the substrate 30 Can also be configured as a one-directional lacquer adhered in series.

At this time, the thickness of the hook needle and the thickness of the molding substrate 10 are appropriately adjusted and adjusted by using the characteristics of the plastic which becomes flexible when the thickness is thin and becomes hard when it is thick.

On the other hand, the hook needles 1 and 2 formed on the basis of the above configuration may be formed on a flexible fabric such as a velcro.

A specific construction method of the hooks 1 and 2 is a method of forming hooks 1 and 2 on a fabric by using an elastic plastic material such as polyester or polypropylene based on a manufacturing technique of fixing hooks on a fabric of velcro A gap 19 of a predetermined size and a mounting and dismounting space 20 are formed by arranging the bottom portion of the base 11 in a standing upright manner so that the spacing between the base and the base is constantly arranged in each row do.

Further, as shown in Fig. 1 (E to Ec), the intervals between the protrusions may be arranged closely so that the protrusions of the next protrusions are located in the middle between the protrusions and the protrusions. 2 (H, G), the height and the overall length of the base 11 of the molded hook needles 1 and 2 are set to be relatively long in order to be placed on the inner surface of the rubber band, , It is preferable to make it as short as possible as shown in Fig. 4 (Ca, Cb). The reason is that the shorter the height and overall length of the base is, according to the "Principle of Force Moment ", it is advantageous to enter and bind without being bent into the gap of the fiber loops (nonwoven web).

The elastic strength of the hook needles according to the present invention should be formed so as to maintain a proper elastic strength so as to withstand the cushion of the fiber loops when the needle tips (14) enter into the gap of the fiber loops engaged therewith do. At the same time, when detaching, the bevel surface should be formed so that it can be properly rotated by the principle of friction and elasticity.

1 (Ed), the corresponding napkin 21 (web) is put on the barbed needles 14 of the hook needles 1 and 2 and lightly pressed on the barbed nail 14, When the pulling force is applied to the first sliding surface 12 in the direction of the first sliding curved surface 12, the respective needlepoints (hooks) are caught by the gap (pore) of the nap like a barb of a fishing needle, Are guided (guided) by a gap 19 between the first sliding surface 12 and the adjacent second sliding surface 15 and are guided by the inclined surface 20 (Or hook effect) as in Fig. 1 (Ee), as if the sponge is shrinked and slipped into the sponge.

1 (Ef, Eg), the yarn threads of the napkin are moved in the direction of the second sliding curved surface (Ef, Eg) by the principle of the beveled surface friction and elasticity, 15) While lifting the bottom portion, the fuzz itself contracts or relaxes due to elasticity so that it can be easily released even with a small force.

As described above, the method of constructing the unidirectional tapping with the hooks 1 and 2 of the present invention and the working principle thereof have been described.

To form the basis of the structure mentioned above principle, in practice so that to roll transient on the sanitary cover (002, the fiber cover, sponge cover, etc.) headphone speaker cover (001) in accordance with the present invention, first, a certain form of detachable over speaker cover method of one configuration for directional velcro (007) in the elastic band (003) and, second, there is a method to configure a one-way velcro (007) directly on the headphone speaker main cover (001).

Regarding the first configuration, as shown in Figs. 2 (A-F), a waterproof rubber watch for a bathroom waterproof watch is provided with a round rubber band-shaped side edge formed with a fixed jaw 005, So that they can be uniformly distributed and bonded at intervals.

As shown in Fig. 2 (G), the unidirectional ratchet applied to the present configuration is such that the height of the prongs 11 of the hook needles 17 (1) 17 or 2 (18) ), Polyester or the like is molded on the molding substrate 10 to manufacture. At this time, it is necessary to flexibly form the molded board so as to be rounded in conformity with the curved surface of the round side of the speaker body rim.

Also, as described above, the unidirectional tap formed by fixing the hooking needles may be cut to a predetermined size so that a certain number of hooking needles exist on the fabric woven with the plastic material.

Particularly, when a superelastic shape memory (alloy or polymer) material is applied to the above-mentioned hook needles described in the above-mentioned [5 to 7], it is possible to prevent plastic deformation, The deformed shape can be smoothly returned to the original shape, so that a more preferable structure can be obtained.

The diameter of each of the hook needles 1 and 2 is about 0.3 mm in diameter. The diameter of the hook needles 1 and 2 may be much thinner or thicker than 0.3 mm depending on the constituent material of the hook needle and the elastic strength . In particular, since the hook 2 is formed longer than the hook 1, the hook 2 is relatively slightly thicker.

The end portion of the barb tip 14 has a degree of "rough feeling" when it is swiped by the tip of the hand, and is appropriately subjected to a rounding treatment so as not to be stuck or scratched by the barb upon contact with the human skin It forms non-sharp.

As shown in FIG. 2 (F), the molded substrate 10 or the fabric having the hooks formed thereon is flexible and can be smoothly formed, but is not stretched like a rubber. Therefore, At the site where the substrate is bonded, stretch disappearance regions 010 are generated. At the same time, the elastic region 009 is naturally present therebetween.

Therefore, if the unidirectional tapping is made long in the stretchable band, it is possible to face the problem of the structural biasedness in which only one portion stretches. In view of the problem of the elasticity disappearance region and the structural polarization, a small-sized unidirectional tapestry is applied to at least two or more side edges of the elastic band (003) as shown in Figs. 2 (A to F) The first sliding surface 12 of the hooking needles 1 and 2 faces the acoustic emission port side of the speaker and is uniformly bonded at regular intervals along respective rims so that the stretchable portion 010 of a certain size is uniformly It needs to be configured to exist.

Therefore, when forming the unidirectional tapes on the elastic bands, it is preferable that the unidirectional tapes are formed as small as possible so that the force of the attachment and detachment force can be evenly distributed in several places, So as to be evenly distributed in several places. At this time, as shown in Fig. 3 (E), one line may be formed along the rim of the elastic band, or two lines may be formed as shown in Figs. 2 (B) and 3 (A) and 3 (C).

Based on such a constitutional principle, in order to actually constitute a stretchable band, a certain mold is made flat and long, and then a rubber solution blended with latex or silicone synthetic rubber material is injected into the band.

Next, the molded substrates 10 are lined and fixed at regular intervals from each other along a length of a mold using a certain tool, so that the molded substrate is placed at a predetermined position in the rubber solution, As shown in FIGS. 2 (D) and 2 (E), a part of the base and the molded substrate are molded and bonded together in the rubber band, thereby forming a long stretchable band with a fixed length and thickness of a predetermined length and thickness.

When the thus formed elastic band is attached to the speaker main body cover, the diameter of the elastic band is larger than the diameter of the cover coupled to the round rim of the speaker body so that proper tension can be maintained by using the elasticity of the rubber itself. Is formed much smaller. That is, it is cut much shorter than the length of the side edge of the cover, and both ends are connected to each other with molten rubber solution.

3 (D), the fixing jig 005 having a relatively small diameter enters and is fixed into the connection gap of the rim of the main body, so that it can be fixed tightly to the cover surface by the constant tension of the rubber . At the same time, since the frictional force of the rubber is great, the elastic bands can not be moved or separated from the cover due to the constant force acting upon attachment / detachment of the sanitary cover (002) . At the same time, there is a great advantage in that only the sanitary cover can be easily and conveniently removed from the hook needles.

On the other hand, when the nylon composite fabric is used as the elastic band, as shown in Fig. 4 (Ca, Cb), the height of the base 11 of the hook needles 1, The formed unidirectional tapes are evenly adhered to the side edges of the elastic band at regular intervals to form a stretchable tap with a band like an adhesive tape. In this case, cut to the appropriate length according to the size of the speaker, and stitch both ends to sew.

Further, in order to prevent slippage due to a constant force acting upon attachment and detachment, the inner surface contacting the speaker cover is coated with a material having a large frictional force such as a latex rubber solution or a silicone synthetic rubber solution.

In particular, it may be more effective to use a rubbery material, such as a computer mouse pad underlay, that has a sticky adhesion. During the coating process, the inner and outer sides of the elastic band are reversed.

On the other hand, when the sanitary cover (002) is detached from the hook needles, in order to secure the safety of wearing, the entire speaker main body (006) is wrapped around the back side of the speaker main body A certain type of auxiliary band 012 formed with attachment and detachment means (013, tie, velcro, hook, button, unidirectional tap) can be additionally constructed in the following manner.

1) When the elastic band and the auxiliary band are both used as the rubber material, they can be molded together with the rubber raw material at the time of molding.

2) When the stretchable band and the auxiliary band are used as stretchable mesh materials, they are separately formed and joined together by stitching (sewing).

3) When the elastic band is used as a rubber material and the auxiliary band is used as a mesh, the corresponding parts of the auxiliary band can be integrally molded together as a rubber raw material.

4) Constitute a suitable combination of stretch mesh material and rubber material.

Secondly , with respect to a method for constructing a unidirectional louver 007 directly on the headphone speaker body cover 001, as shown in Figs. 4 (Ca and Cb), the height of the pillar 11 of the hook needles 1 and 2 At least two or more uni-directional squeezers formed at lower positions are equally connected at regular intervals along the rim of the cover as shown in Figs. 4 (A, B, C).

Further, the height of the base of the hook needles may be formed to be higher by the thickness of the body cover, and the hooks may protrude from the outer surface of the cover while the molding substrate is adhered to the inner surface of the cover. At this time, the hook needles may be formed in one line as shown in Fig. 3 (E), or may be formed in two lines as shown in Fig. 4 (C).

When the sanitary cover 002 is pushed on the cover 001 thus formed or on the elastic stretch band as shown in Figs. 3 (A, D) and 4 (A, C), the inner detachable portion 008, Is slid smoothly along the first sliding surface 12 of the hook needle and in the opposite direction is caught by the needle tip 14 of the hook like a barb of a fishing needle, Since the sanitary cover can be easily and conveniently attached by the effect, it is possible to secure both convenience of attachment and detachment and safety of wearing.

When the sanitary cover is detached, the sanitary cover itself composed of the porous fiber or the sponge is used to take up a part of the outer edge of the sanitary cover, and when the sanitary cover is pulled up by the fingertip, the number of hook needles is reduced. It is possible to easily separate it with a very small force.

The sanitary cover (002) of the present invention is formed by processing a material such as a cotton, a cotton, a sweat absorbent, or a natural, synthetic, or nylon synthetic fiber with good breathability. At this time, as shown in Figs. 3 (A), 3 (B) and 4 (A) and 4 (B), when the center is convexly worn, It is convenient to wear as it is naturally inserted into the inside.

Since the hook needles 1 and 2 of the unidirectional tapping device of the present invention have a needle-like structure, the loop material to be engaged therewith is a loop-shaped fabric having a porous gap through which the hook needles pass And all kinds of fibers can be used as the loop material.

A variety of materials such as porous paper towels and porous sponges formed by chemical synthesis of natural pulp can be selectively used as the loop material, and thus it is a great advantage of the present invention that the choice of the loop material is wide accordingly .

Therefore, the loop material applied to the detachable portion 008 on the inner surface of the sanitary cover also need not necessarily be a strongly detachable nylon composite fabric. In the case of a disposable sanitary cover made of a paper towel or the like, the end of the outer edge can be folded once and used as a loop material.

Alternatively, a paper towel cover may be turned over, and a paper towel, a sponge or the like made in advance may be adhered and then mechanically turned over again. This has the advantage of being capable of mass production at a much lower cost than a nonwoven web woven with polypropylene or the like.

On the other hand, the bent end of the J-type hook of the Velcro is roundly rounded without being roughened, and the unidirectional lacquer, which is regularly arranged in one direction on the woven fabric, Then,

At least two or more of the curved circular curved portions of the hooks are directed toward the acoustic emission port side of the speaker in a side edge of the headphone speaker main body cover or on a side surface of a certain type of elastic band to be attached and detached on the speaker main body cover Or may be dispersively combined.

In this way, when the sanitary cover formed on the inner surface of a suitable fiber loop is pushed in, it slides on the curved surface of the hook, and in the opposite direction, the hook is easily caught in the gap of the fluff.

In addition, since the area of the unidirectional tapper is small and the number of hooks (hooks) is small, an effect that the sanitary cover can be easily and conveniently removed with the principle of elasticity is obtained.

The present invention can easily and conveniently attach and detach a sanitary cover to a headphone speaker cover by applying a unidirectional tap with hooks using the principle of moment of force and the principle of bevel friction and elasticity, There is a possibility.
