A band piece and a second band piece, each having a hole for engaging with the ear cup, and having a third pin that connects the hole of the ear cup and the hole of the band piece. A radial ridge or groove is provided around one of the hole of the ear cup and the hole of the band piece, and at least the other of the hole of the ear cup and the band piece is engaged with the ridge or groove. One ridge or groove is provided.

  The ear warmer of the present invention is an ear warmer made of a skeleton composed of an ear cup and a band and a fabric covering the skeleton, and has the band length adjuster.

In the first aspect of the present invention, the first and second band pieces can be slid by the distance of the long hole of the first band piece, and the second pin can slide by the distance of the long hole of the second band piece. Is possible. Therefore, when the first and second band pieces are integrated, the band is the shortest when the long holes of the band pieces coincide with each other and the longest when the long holes are completely shifted. That is, the length can be adjusted by one long hole. Moreover, since each band piece is engaged and supported by two pins, it does not shake in the vertical direction. In addition, since each band piece is connected by a pin, it can be easily assembled.

According to the third aspect of the present invention, since one T-shaped protrusion is used for either the first or second band piece, it is possible to omit one of the first and second pins, which is economical. Is.

In the tenth aspect of the present invention, since the intermediate band is further provided and the number of the band pieces is three, the length adjustment distance can be extended.

In the eleventh aspect of the present invention, since the ear cup can be rotated stepwise with respect to the band end, the position of the ear cup can be finely adjusted. Furthermore, even after the ear cup is adjusted to an appropriate position, the engagement between the heel and the groove is maintained, so that the proper position can be maintained.

  The first and second pins used in the present invention are divided into two parts before mounting, but it is preferable to combine them so-called hell fitting and cannot be easily separated. Use of this pin facilitates assembly and repair of the band piece.

  It is preferable to provide unevenness on the upper and lower sides of the first and second band pieces used in the present invention so that the finger can be easily put on when adjusting the length of the band to make it difficult to slip. The unevenness is preferably a waveform that allows a finger to fit into the recess.

  The upper and lower widths of the long holes of the first and second band pieces may be uniform, or the width may be provided with a waveform. When the width is large or small, the pin receives resistance at a narrow width, so that the slide movement distance of each band can be adjusted stepwise.

  The length of the long hole of the first and second band pieces is usually about 3 to 10 cm, but it can be extended from the vicinity of the short hole to the vicinity of the center of the ear cup by nearly 20 cm. By extending so long, the effect of compact folding when each band is slid and shortened to the limit is born.

  Further, at least one hook-shaped protrusion in the width direction is provided at a position adjacent to the long hole of one band piece, and a plurality of grooves are provided in the width direction at a position adjacent to the long hole of the other band piece, The protrusion and the groove can be engaged with each other. By doing so, the position is stabilized when the protrusion and the groove are engaged with each other, so that the slide movement distance of each band can be adjusted stepwise.

  For the same purpose, a plurality of hook-shaped protrusions are provided in the width direction at positions adjacent to the long holes of the first band piece, and the hook-shaped protrusions are formed by the T-shaped protrusions at the end of the second band piece. It can also be engageable with the space.

FIG. 2 is a perspective view showing a skeleton state of the ear warmer 1. The ear cup 2 is attached to both ends of the band 3, but only one of them is shown here for easy viewing. The ear warmer 1 is formed by covering this skeleton with a soft cloth.

FIG. 3 is an exploded perspective view of the band 3. As shown in this figure, the band 3 is composed of two band pieces 4 and 5, which are integrated in an assembled state as shown in FIG. The two band pieces 4 and 5 are slidable with respect to each other, whereby the length can be adjusted.

The two band pieces 4 and 5 have the same shape, but when assembled, they are used by inverting one side so as to be symmetrical. Hereinafter, they are referred to as “first band piece 4” and “second band piece 5”. Each band piece 4, 5 is provided with irregularities 41, 51 on the upper and lower sides.

The first band piece 4 has a short hole 42 (first short hole) for attaching the ear cup 2 at one end. The multi-end has a short hole 43 (second short hole) for inserting an engaging pin. Near the second short hole 43, a long hole 44 is provided on the band side.

The second band piece 5 has a short hole 52 (first short hole) for attaching the ear cup 2 at one end. The multi-end has a short hole 53 (second short hole) for inserting an engaging pin. In the vicinity of the second short hole 53, a long hole 54 is provided on the band side.

Two sets of engaging pins 6 and 7 are used. Hereinafter, they are referred to as “first pin 6” and “second pin 7”. Each pin is divided into two parts 61, 62; 71, 72 before mounting, but when combined, it becomes a so-called hell fit and cannot be easily separated and is known per se.

In the assembled state, the first pin 6 is inserted through the long hole 44 of the first band piece 4 and the second short hole 52 of the second band piece 5, and the long hole 54 of the second band piece 5 and the first band piece 4 The second pin 7 is inserted through the second short hole 42.

In the first and second band pieces 4, 5, the first pin 6 can slide by the distance of the long hole 44 of the first band piece 4, and the second pin 7 is the distance of the long hole 54 of the second band piece 5. Is only slidable. Therefore, when the first and second band pieces 4 and 5 are integrated, the band 3 is shortest when the long holes 44 and 54 of the band pieces coincide with each other, and when the long holes are completely displaced. The longest. That is, the length can be adjusted by one long hole. In addition, since the band pieces 4 and 5 are engaged and supported by the two pins, they do not shake in the vertical direction.

The irregularities 41 and 51 on the upper and lower sides of the band piece described above have an effect of making it easier to put a finger on the band length and making it difficult to slip.

FIG. 4 is a perspective view showing a method of engaging the band 3 and the ear cup 2. The ear cup 2 is attached to both ends of the band 3, but only one of them is shown here for easy viewing.

  As described above, there are short holes 42 and 52 for attaching ear cups on each band side. A short hole 21 is also provided on the ear cup 2 side for attaching the band. These short holes are also connected by the pin 11.

Eight depressions 22 are provided radially on the outer surface around the short hole 21 of the ear cup 2. On the other hand, on the band 3 side, one hook-like protrusion 45 is provided on the inner surface around the short hole 42. The ear cup 2 can be rotated 360 ° with respect to the band 3, and when the band-shaped protrusion 45 of the band is engaged with the recess 22 of the ear cup, the respective positions are stabilized. Thus, the fact that the ear cup 2 can be rotated 360 ° with respect to the band 3 is useful for folding the ear cup when not in use and making it smaller.

  As shown later in Example 8 (FIG. 12), a hook-shaped protrusion is provided on the outer surface around the short hole of the ear cup, and a plurality of depressions are provided on the inner surface around the short hole on the band side. It is also possible.

  FIG. 5A is a second embodiment of the present invention. For the sake of clarity, a band that is actually curved is shown as a flat surface.

  In the second embodiment, the band 3A includes three band pieces 4A, 5A, and 8. The left and right band pieces 4A and 5A are the same as in the first embodiment. The intermediate band piece 8 has engaging short holes 81 and 82 at the left and right ends, and two elongated holes 83 and 84 are sandwiched between these short holes. Four pins are used to join the three bands.

A plurality of grooves 46D are provided in the width direction at adjacent positions.

  When the two band pieces 4D and 5D are slid relative to each other, the position is stabilized when the hook-shaped protrusion 55D is fitted into the groove 46D, but is unstable at other positions. Therefore, the slide movement distance can be adjusted stepwise.

  8 and 9 show a sixth embodiment of the present invention. FIG. 8 is an exploded front view, FIG. 9A is a side view of a band piece on one side, and FIG. 9B is a side view in a state where the bands are combined. In FIG. 8, for easy understanding, the band portions 4E and 5E are drawn flat. Parts having the same functions as those of the first embodiment are denoted by the same reference numerals with “E”, and description thereof is omitted.

  In this embodiment, the ear cup 2E is integrated with the band pieces 4E and 5E and cannot be rotated. Moreover, the long holes 44E and 54E of the band pieces 4E and 5E extend to the vicinity of the center of the ear cup. A side view of the band piece 5E on one side is as shown in FIG. 9 (a). When the two band pieces 4E and 5E are slid along the long holes 44E and 54E and shortened to the limit, they are folded compactly as shown in FIG. 9B.

  FIG. 10 is a perspective view showing Example 7 of the present invention. Since it is very similar to the first embodiment (FIG. 4), the same reference numerals are used for components having the same function, the same reference numerals are used, and the description thereof is omitted.

  Example 7 is different from Example 1 in that the unevenness on the upper and lower sides of each of the band pieces 4F and 5F has a large waveform. By doing so, since the finger fits into the corrugated depression, the sliding movement of each band piece 4F, 5F is facilitated.

  11-16 is Example 8. FIG. FIG. 11 is a perspective view of the entire skeleton. FIG. 12 is an exploded perspective view. FIGS. 13A and 13B are cross-sectional views in two states in which the length of the band is changed by adjusting the band. 14A is a plan view, FIG. 14B is a left side view, FIG. 14C is a front view, FIG. 14D is a right side view, and FIG. 14E is a longitudinal sectional view. 15A is a plan view, FIG. 15B is a left side view, FIG. 15C is a front view, FIG. 15D is a right side view, and FIG. FIG. 16 is a (a) plan view, (b) front view, (c) right side view, and (d) left side view of the ear cup.

  Example 8 is different from Examples 1 to 7 in the following points.

(1) For example, in Example 1, as shown in FIG. 3, the inner and outer two band pieces 4 and 5 had short holes 43 and 53 and long holes 44 and 45, respectively. In the eighth embodiment, of the two inner and outer band pieces 4G and 5G, the combination of the short hole and the pin fitted therein is replaced with the T-shaped protrusion 56 in the band piece 5G located inside. As shown most clearly in FIGS. 14 (a) and 14 (b), the T-shaped protrusion 56 is provided outward at the end of the band piece 5 and extends in a short-diameter neck and an elliptical shape. Has a top. The neck is slidable along the long hole 44G of the other band piece 4G. Since the diameter of the top is larger than the width of the long hole, the T-shaped protrusion 56 does not come off.

  In the eighth embodiment, the combination of the short hole of the outer band piece 4G and the pin 6G fitted thereto is not replaced with a T-shaped protrusion for the convenience of manufacturing. This is because it is difficult to adopt such a configuration for both the inner and outer band pieces because the T-shaped protrusions need to be twisted and inserted into the elongated holes of the other band piece. However, depending on the materials used, such replacement is not impossible.

  In the eighth embodiment, as compared with the first to seventh embodiments, at least one pin can be used, which is economical.

(2) In the fifth embodiment (FIG. 7), the stepwise adjustment of the band length is performed by using one ridge-like protrusion 55D in the width direction provided at a position adjacent to the long hole 54D of the inner band piece 5D. This is due to the engagement / disengagement of the plurality of grooves 46D in the width direction provided at a position adjacent to the long hole 44D of the other band piece 4D. In Example 8, as best shown in FIGS. 11 to 13, the space 58 located on both sides of the neck of the T-shaped protrusion 56 of the inner band and the outer surface of the outer band are provided adjacent to the long hole. This is due to engagement / disengagement of the plurality of hook-shaped protrusions 47 in the width direction.

(3) In the first embodiment (FIG. 4), the stepwise rotation of the ear cup relative to the end of the band is eight radial depressions 22 provided on the outer surface of the ear cup 2 and one on the band 3 side. This was due to the engagement / disengagement of the hook-shaped protrusion 45 of the above. In the eighth embodiment, as best shown in FIGS. 12 and 16, the eight radial recesses 24 provided at the proximal end 23 of the ear cup 2G and the two protrusions 57 on the band 3G side (FIG. 14). By (e)) engagement / disengagement.

(4) In the eighth embodiment, the shape of the ear cup 2G (see FIG. 16) and the shape of the pins 11G and 6G (see FIGS. 12 and 13) are greatly different from those of the first to seventh embodiments. It is a difference.

  FIG. 17 is a cross-sectional view of the ear warmer according to the ninth embodiment.

  Example 9 is very similar to Example 8. The difference is that the first band piece and the second band piece of Example 8 are reversed. That is, the T-shaped raised portion 48 is provided inwardly at the end of the band piece 4H, and has a short-diameter neck portion and an elliptical apex portion. The neck portion is slidable along the long hole of the other band piece 5H. Since the diameter of the top is larger than the width of the long hole, the T-shaped protrusion 48 does not come off. Compared with the first to seventh embodiments, the ninth embodiment can reduce the use of at least one pin and is economical.

  The band length is adjusted stepwise in the width direction provided in the space on both sides of the neck of the T-shaped protrusion 48 of the outer band 4H and the outer surface of the inner band 5H adjacent to the long hole. By engaging / disengaging the plurality of protrusions 59.
