Description

BACKGROUND OF THE INVENTION AND RELATED ART STATEMENT

The present invention relates to a buckle for connecting a strap.
As a buckle comprising a base and a tool holder, Patent Reference 1 is available. A lip and a resilient arm are formed in the base and a flange is included in the tool holder; the tool holder is combined with the base by inserting the flange below-the lip.
In the buckle disclosed in Patent Reference 1, however, either the outline of the flange is polygonal in shape, or the inner contour of the lip is polygonal in shape. Thus, the tool holder cannot be turned when combined with the base. That is, once the tool holder is combined with the base, unless it is removed, the orientation of the holder section of the tool holder cannot be changed.
Patent Reference 1: Japanese Patent Publication (Kokai) No. 2002-112810.
In view of the problem described above, an object of the present invention is to provide a buckle, in which a strap connected via the buckle appropriately holds an article of various types so that the article can be turned to achieve an easy-to-use orientation by utilizing the buckle.
Further objects and advantages of the invention will be apparent from the following description of the invention.

SUMMARY OF THE INVENTION

In order to achieve the objects described above, according to the present invention, a buckle comprises a buckle body and a holder member rotatably and detachably attached to the buckle body for holding an article of various types.
According to such a construction, a strap connected via the buckle body holds an article of various types, so that the article can turn to achieve an easy-to-use orientation. When there is no need to hold any article, the holder member can be removed from the buckle body, so that the buckle body can be used by itself.
According to the present invention, a buckle may comprise a buckle body and a holder member rotatably and detachably attached to the buckle body for holding an elongated article, such as a strap, string, linear, bar, or tubular material.
With the above construction, the elongated article can be held by the buckle body without difficulty when oriented so that the lengthwise direction of the elongated article not only coincides but also intersects with the direction in which the straps connected via the buckle body extend. In other words, when the elongated article has to be moved or relatively moved so as to change the angle formed by the center line of the article and the center lines of the straps, which are connected via the buckle body, in order to use the elongated article in the held state, the holder member can be turned accordingly. In such an instance, deformation or the like of the elongated article being held can be prevented. When there is no need to hold any elongated article, the holder member can be removed from the buckle body, so that the buckle body can be used by itself.
According to the present invention, a buckle may comprise a female part included in either the buckle body or the holder member and a male part in the other of the two. The male part has a head and a neck. The female part has an insertion space communicating with an insertion opening for the head of the male part; a through hole formed integrally in one of a wall forming the insertion space, communicating with the insertion space, and having an inner peripheral surface formed along an arc having a diameter for passing the neck of the male part and not passing the head therethrough; and a guide groove for the neck of the male part communicating with the through hole, connected to an edge on a side of the insertion opening of the wall, having an opening opened outwardly at the edge. The neck of the male part is inserted into the through hole while resiliently spreading the guide groove, and the head is fitted into the insertion space through the insertion opening.
With such a construction, the holder member can be rotatably and detachably combined with the buckle body connecting the strap in an appropriate manner, thereby allowing it to tolerate, with a high degree of flexibility, changes in the orientation of the elongated article so held according to the use by allowing the holder member to turn. In other words, the female part and the male part can be combined by fitting the head of the male part into the insertion space of the female part so as to prevent the head from easily slipping out.
Since the through hole of the female part has the inner peripheral surface, the male part is smoothly turned using the through hole as a shaft hole. When there is no need to have the buckle body hold an article, the head can be pulled out by pulling out the neck of the male part which has been located in the through hole through the guide groove, while allowing the neck to resiliently spread the guide groove, thereby separating the buckle body from the holder member in a one-touch operation.
The holder member may be formed of a clamp for receiving and holding an elongated article from a lengthwise side into a clamp interior while allowing the elongated article being inserted to resiliently spread the clamp entrance.
With such a construction, the holder member is allowed to appropriately hold an elongated article, such as a tube or pipe, in a one-touch operation, and tolerate, with a high degree of flexibility, changes in the orientation of the elongated article so held according to the use by allowing the holder member to turn.
The buckle body may comprise a male buckle and a female buckle constructing a side release buckle. One of the male part and the female part is disposed on an outer surface of the female buckle.
With such a construction, engaging the male buckle and the female buckle connects the strap fastened to the male buckle and the strap fastened to the female buckle, enables the female buckle so connected to the male buckle to appropriately hold an elongated article via the holder member, and tolerates, with a high degree of flexibility, changes in the orientation of the elongated article so held according to the use by allowing the holder member to turn.
The buckle body may have a strap fastening section comprising strap inserting or passing sections on both sides of a middle cross bar.
With such a construction, the straps can be connected via the buckle body in the condition where the position in which the buckle is fastened to at least one of the straps to be connected 4. via the buckle body is made adjustable by the fastening section of the buckle. At the same time, the buckle body is capable of appropriately holding an elongated article via the holder member, and tolerating, with a high degree of flexibility, changes in the orientation of the elongated article so held according to the use by allowing the holder member to turn.
According to the present invention, the straps that are connected via the buckle body are allowed to hold an article of various types so that the article can turn to achieve an easy-to-use orientation.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Hereunder embodiments of the present invention will be explained based on FIGS. 1 to 25(a) and 25(B). FIGS. 1 to 7 illustrate one example of a holder member 2 comprising the buckle, FIGS. 8(A) and 8(B) show another example the holder member 2, FIGS. 9(A) and 9(B) show another example, and FIGS. 25(A) and 25(B) show yet another example.
FIG. 10 illustrates one example of a buckle body 1 comprising the buckle, FIGS. 11 to 13 show another example of the buckle body 1, FIG. 14 shows a female buckle 13 comprising another example of the buckle body 1, FIGS. 15 to 21 show a female buckle 13 comprising another example of the buckle body 1 in the state wherein it is combined with the holder member 2 shown in FIGS. 1 to 7. FIGS. 22 to 24 show yet another example of the buckle body 1.
The buckle in these embodiments is used to connect straps W. Such a buckle is typically used to connect two straps W, W via the buckle. More specifically, when used in a backpack, for example, the buckle is used to detachably connect a pair of right and left waist straps or chest straps via the buckle, or position adjustably fasten and connect the lower ends of pad sections, which comprise shoulder straps whose upper ends are secured to the upper section of the backpack, and the upper ends of lower draw-out tapes whose lower ends are secured to the lower section of the backpack, via the buckle.
Such a buckle includes a buckle body 1 that connects the straps W together and a holder member 2 that holds an article of various types.
In the examples shown in the figures, the buckle includes a holder member 2 having a structure that is suited for holding an elongated article, such as a strap, string, linear, bar, or tubular material. The holder member 2, moreover, is rotatably and detachably provided in the buckle body 1.
As for an elongated article, a tube, a pipe, a rod, a cord, a string, a wire or the like is anticipated. More specifically, anticipated applications in a backpack, for example, include holding at the position where the buckle is disposed a tube that functions as a straw connected to a container for supplying drink to a backpack user, or a reel that reels in and out a string constructed so as to tie or fasten an article of various types at the end of the string.
According to such a construction, the straps W connected via the buckle body 1 can hold an article of various types so that the article can turn to achieve an easy-to-use orientation. When there is no need to hold an article, the holder member 2 can be removed from the buckle body 1, so that the buckle body 1 can be used by itself.
When such an article is elongated in shape, in particular, the buckle body 1 is able to hold the article without difficulty when the article is oriented so that the lengthwise direction not only coincides but also intersects with the direction in which the straps W connected via the buckle 1 extend. In other words, when the elongated article has to be moved or relatively moved so as to change the angle formed by the center line of the article and the center lines of the straps W, which are connected via the buckle body 1, in order to use the elongated article in the held state, the holder member 2 can be turned accordingly. In such an instance, deformation or the like of the elongated article being held can be prevented. When there is no need to hold any elongated article, the holder member 2 can be removed from the buckle body 1, so that the buckle body 1 can be used by itself.
In this embodiment, more specifically, a female part 3 is provided in either the buckle body 1 or the holder member 2, and a male part 4 is provided in the other of the two. In the examples shown in the figures, the male part 4 is provided in the holder member 2, while the female part 3 is provided in the buckle body 1.
The male part 4 has a head 40 and a neck 41. In the examples shown in the figures, the male part 4 is composed of a disc-shaped head 40 and a cylindrical shaft-shaped neck 41 whose one shaft end is integrally connected to one face of the head 40 substantially in the center and the other shaft end is integrally connected to the holder member 2.
In the examples shown in the figures, moreover, a substantially square sheet base 42 with one surface integrally connected to the holder member 2 is provided, and the other shaft end of the neck 41 is connected to the other surface of the base 42 substantially in the center. On that surface of the base 42, a rise 43 that projects from that surface is formed on each of a pair of opposing sides at a substantially mid position lengthwise. The projecting end surface of the rise 43 forms a gradual curve.
The female part 3 has the following:

- (1) an insertion space 31 continued from an insertion opening 30 for the head 40 of the male part 4,
- (2) a through hole 33 created in one of the walls 32 that forms the insertion space 31, connected to the insertion space 31, and has an inner peripheral surface that follows the arc of a phantom circle having a diameter to allow the neck 41 of the male part 4 pass through but not the head 40, and
- (3) a guide groove 34 for the neck 41 of the male part 4 that is connected to the through hole 33, continued to the edge of the wall 32 on the side of the insertion opening 30, and opened outwardly at that edge.

In the examples illustrated in the figures, the female part 3 is formed by supporting a top plate 35 having an outline that is substantially shaped after the outline of the base 42 of the male part 4 with a support plate 36, which is integrally connected to a pair of opposing sides of the top plate, so as to form the insertion space 31 below the inner surface of the top plate 35. In the examples shown in the figures, moreover, the through hole 33 is formed substantially in the center of the top plate 35. The insertion opening 30 is formed on one side of the remaining pair of sides of the top plate 35, which are not supported by the aforementioned support plate 36. The aforementioned guide groove 34 is formed between the substantial center of that side of the remaining pair of sides and the through hole 33.
In the examples shown in the figures, the groove width of the guide groove 34 in the center is slightly smaller than the diameter of the neck 41 of the male part 4. The diameter of the aforementioned phantom circle where the inner peripheral surface of the through hole 33 is positioned is substantially equal to the outer diameter of the neck 41 of the male part 4. At the free end of the guide groove 34, i.e., the entrance, both groove walls are tilted in the direction to gradually spread the groove width of the guide groove 34 as they gain distance from the center of the guide groove 34 to make the insertion of the neck 41 of the male part 4 into the groove 34 easier. In the examples shown in the figures, moreover, recesses 37 having the depth and width for the rises 43 formed in the base 42 of the male part 4 to enter are formed in the substantial centers of the sides supported by the support plate 36 in the aforementioned top plate 35.
In this embodiment, moreover, the neck 41 of the male part 4 is inserted to the aforementioned through hole 33 while resiliently spreading the guide groove 34, and the head 40 is fitted into the insertion space 31 through the insertion opening 30.
In this embodiment, therefore, the holder member 2 can be rotatably and detachably combined with the buckle body 1 that has connected to the straps W, thereby allowing the buckle to tolerate, with a high degree of flexibility, changes in the orientation of the elongated article so held according to the use by allowing the holder member 2 to turn. In other words, the female part 3 and the male part 4 are combined without allowing the head 40 of the male part 4 to easily slip out of the insertion space 31 by inserting the head 40 into the insertion space 31 of the female part 3. Since the through hole 33 of the female part 3 has the aforementioned inner peripheral surface, the male part 4 is smoothly rotated using the through hole 3 as a shaft hole. When there is no need to have the buckle body 1 hold an elongated article, the buckle body 1 and the holder member 2 can be separated with a one-touch operation by pulling out the neck 41 of the male part 4 that has been located in the through hole 33 from the insertion space 31 through the guide groove 34.
In the examples shown in the figures, the male part 4 and the female part 3 are combined as described above when the outer surface of the top plate 35 contacts the lower surface of the base 42 so that the pair of rises 43 formed in the base 42 of the male part 4 respectively fits into the pair of recesses 37, 37 from above (the state shown in the section with the solid line in FIG. 21).
When the male part 4 is turned or relatively turned using the through hole 33 as a shaft hole from this state, the base 42 is flexibly deformed so as to allow the pair of rises 43 to slip out of the recesses 37, and, as a result, the rises 43 slip out of the recess 37. Then, the base 42 regains its original shape at the turned position where one of the pair of rises 43 slips into the side of the pair of sides of the top plate 35 where the recesses 37 are not formed, while the other of the pair of rises 43 slips into the entrance of the guide groove 34. As a result, the inner surface of one of the pair of rises 43 is caused to have a planar contact with the side of the pair of sides of the top plate 35 where no recesses 37 are formed, while the other of the pair of rises 43 is housed in the entrance of the guide groove 43.
When the male part 4 is further turned or relatively turned from this state (shown in FIG. 21 in the section with imaginary line), the base 42 is flexibly deformed again and regains its original shape in the turned position where one of the pair of rises 43 slips into the aforementioned recess 37. As a result, the pair of rises 43 fits into the corresponding recesses 37. That is, in this embodiment, the holder member 2 can be temporarily fastened at the positions where it is turned about 90 degrees normally and in reverse.
FIGS. 1 to 9(A) and 9(B) show an example of a clamp-shaped holder member 2 for receiving and holding an elongated article from the lengthwise side into the clamp interior 21 while allowing the elongated article being inserted to resiliently spread the clamp entrance 20.
More specifically, in the example shown in FIGS. 1 to 7, the holder member 2 can hold the elongated article as described above by integrally providing the male part 4 to the holder member 2, and integrally connecting the upper face of the base 42 of the male part 4 to the lower parts of a pair of clamp pieces 23 that are curved except for the upper sections so that the opposing sides become the inner sides of the curve. The distance between the upper ends 23 a of the pair of clamp pieces 23 is slightly smaller than the diameter of the elongated article to be held. That is, in this example, the space between the curved sections 23 b of the pair of clamp pieces 23 forms the aforementioned clamp interior 21, and the space between the upper ends 23 a forms the clamp entrance 20.
In the example shown in FIGS. 8(A) and 8(B), the male part 4 is also integrally disposed to the holder member 2. In this example, the holder member 2 is composed of base pieces 24, which project sideways from both of the side sections where rises 43 are formed on the base 42 of the male part 4, support pieces 25, which project upwardly from the projecting ends of the base pieces 24, and clamp pieces 26, which extend downwardly from the projecting ends of the support pieces 25 so that a space is created between each clamp piece and the inner surface of the support piece 25. The pair of clamp pieces 26 disposed as above is curved so that the opposing sides become the inner sides of the curve. The distance between the connections 26 a, which connect the clamp pieces 26 and the support pieces 25, is slightly smaller than the diameter of an elongated article to be held. That is, in this example, the space between the curved sections 26 b of the pair of clamp pieces 26 forms the aforementioned clamp interior 21, and the space between the connections 26 a forms the clamp entrance 20.
Likewise, in the example shown in FIGS. 9(A) and 9(B), the male part 4 is integrally disposed to the holder member 2. In this example, the holder member 2 is composed of a base piece 27, which projects sideways from one of the side sections where the rises 43 are formed on the base 42 of the male part 4, and a clamp piece 28, which rises to form a curve so that the side that turns from the other side section to the first side section becomes the inner side of the curve, and the distance between the end of curve 28 a and the upper surface of the base piece 27 is slightly smaller than the diameter of the article to be held. That is, in this example, the inner area of the curved section 28 b of the clamp piece 28 forms the aforementioned clamp interior 21, and the space between the end of curve 28 a and the upper surface of the base piece 27 located directly below forms the clamp entrance 20.
In these embodiments, therefore, the holder member 2 is allowed to appropriately hold an elongated article, such as a tube or pipe, with a one-touch operation, and tolerate, with a high degree of flexibility, changes in the orientation of the elongated article so held according to the use by allowing the holder member 2 to turn.
In the example shown in FIG. 10, moreover, an open section 10 through which the strap W is threaded is provided at each end of the buckle body 1, and the female part 3 in the middle.
In the example shown in FIGS. 11 to 21, the buckle 1 is composed of a male buckle 12 and a female buckle 13, comprising a side release buckle, and the aforementioned female part 3 is disposed on the outer surface of the female buckle 13.
In the examples shown in the figures, the female buckle 13 is constructed to form a flat tube with one tube end open where the legs 121 of the male buckle 12 are introduced therein. The female buckle 13 has a window 131 on each side where the width is narrowed in the direction the legs 121 are introduced. The open section 10 for the strap W is formed at the other end of the female buckle 13. The male buckle 12 has a base 122 that includes two paralleled open sections 10 for the strap W, and a pair of legs 121 that is integrally connected with the base 122 at one end, both legs projecting from the base 122 in the same direction. A rise 123 for catching is formed in each of the pair of legs 121 on the side not facing the other leg.
In the examples shown in figures, when the pair of legs 123 of the male buckle 12 is inserted into the female buckle 13, the rises 123 for catching are deflected inwardly once by the inner surfaces of the narrowed sides of the female buckle 13, and resiliently regain their original shapes at the location where the rises 123 are allowed to enter the windows 131. When the rises 123 of the pair of legs 121 fit into the corresponding windows 131, the strap W passing through the open sections 10 of the male buckle 12 and the strap W passing through the open section of the female buckle 13 are connected via the buckle. The base 122 of the male buckle 12 has a middle cross bar 124 and an end cross bar 125 defined by the two open sections 10.
By passing the strap W from the back side of the male buckle 12 around the middle cross bar 124 to pull it out on the front side of the male buckle 12, and pulling this pulled-out section again towards the male buckle 12 past the back side of the end cross bar, the portion of the middle cross bar 124 and the portion of the end cross bar 125 that face the open section 10 located between the middle cross bar 124 and the end cross bar 125 abut closely against the strap W so long as tension works against the strap W, thereby negating any change to occur in the position where the buckle body 1 is fastened to the strap W (FIG. 12). In other words, in the examples shown in the figures, the male buckle 12 has a fastening section 11 for the strap W.
In the examples shown in the figures, moreover, the aforementioned female part 3 is formed on the broad-width surface at one tubular end of the female buckle 13. In the examples shown in the figures, the guide groove 34 of the female part 3 is formed towards the edge of that tubular end of the female buckle 13. The insertion space 31 for the head 40 of the male part 4 is formed between the top plate 35 and the broad-width surface of the female buckle 13. In other words, in the examples shown in the figures, the female part 3 is configured as a rise formed on the outer surface of the female buckle 13. In the examples shown in the figures, moreover, the broad-width surface of the female buckle 13 that forms the insertion space 13 is provided with a slit 132 which is open at that tubular end of the female buckle 13 and formed directly below and along the guide groove 34. The slit 34 makes it easier for the guide groove 34 to flexibly spread.
In these embodiments, therefore, engaging the male buckle 12 and the female buckle 13 connects the strap W fastened to the male buckle 12 and the strap W fastened to the female buckle 13, enables the female buckle 12 so connected to the male buckle 13 to appropriately hold an elongated article via the holder member 2, and tolerate, with a high degree of flexibility, changes in the orientation of the elongated article so held according to the use by allowing the holder member 2 to turn.
In the example shown in FIGS. 22 to 24, the buckle body 1 has a fastening section 11 for the strap W that has two passing sections 10 for the strap W on both sides of the middle cross bar 141.
In the example shown in the figures, the middle cross bar 141 is disposed to span over the two opposing sides of a frame-shaped portion 14, and the two passing sections 10 are formed in the frame-shaped portion 14. One strap W passes around and is connected to one of the end cross bars 142 (one end of the frame-shaped portion 14 formed substantially in parallel with the middle cross bar 141).
By passing another strap W from the back side of the buckle body 1 around the middle cross bar 141 to pull it out once on the front side of the buckle body 1, and pulling this pulled-out section out again to the side of the buckle body 1 past the back surface of the other end of the frame-shaped portion 14 formed substantially in parallel with the middle cross bar 141, namely, the end cross bar 143, the portion of the middle cross bar 141 and the portion of the end cross bar 143 that face the passing section 10 located between the middle cross bar 141 and the end cross bar 143 abut closely against the strap W so long as tension works against that strap W, thereby negating any change in the position where the buckle body 1 is fastened to the strap W. That is, in the example shown in the figures, the fastening section 11 for the strap W is constructed with the middle cross bar 141 and the adjacent end cross bar 143 of the buckle body 1. Moreover, an overhang 144 is formed from the end on the surface of the end cross bar 143, and the aforementioned female part 3 is formed on the surface of this overhang 144.
In this embodiment, therefore, the straps W can be connected via the buckle body 1 in the condition where the position in which the buckle is fastened to at least one of the straps W to be connected via the buckle body 1 is made adjustable by the fastening section 11 of the buckle 1. At the same time, the buckle body 1 is capable of appropriately holding an elongated article via the holder member 2, and tolerating, with a high degree of flexibility, changes in the orientation of the elongated article so held according to the use by allowing the holder member 2 to turn.
FIGS. 25(A) and 25(B) illustrate an example wherein the holder member 2 is constructed with a case 29 that houses a reel (omitted in the figure) for reeling in and out a string 28 including a fastening section 28 a at the end of the string for an article of various types. The case 29 houses the reel so as to cause the reel to perform normal rotation by pulling the string 28 out of the case 29, and also contains biasing means, such as a spiral spring, to accumulate bias force to cause the reel to perform reverse rotation utilizing the normal rotation of the reel. When the pull-out operation of the string 28 ceases, the string 28 that has been pulled out is reeled in and rewound within the case 29 using the reverse rotational bias. In the example shown in the figure, the male part 4 is formed on one surface of the case 29. The male part 4 of the case 29 is combined with the female part 3 of the buckle body 1 to configure the buckle. By pulling the string 28, the case 29, namely, the holder member 2 for the string 28, is turned in a direction easiest for pulling the string 28.
The disclosure of Japanese Patent Application No. 2004-211550, filed on Jul. 20, 2004, is incorporated in the application.
