Problems to be Solved by the Invention

A main object of the present invention is to allow two members forming this type of cord lock to be combined in a condition with the least possible influences to a thickness and the like of a cord lock while securing the easiness of an operation and a degree of freedom in a shape.

Means for Solving the Problems

In order to obtain the aforementioned object, in a first aspect of the present invention, a cord lock comprises a first member including a first passage portion and a second passage portion for a cord; a second member combined with the first member so as to be capable of moving to rise and fall as a support point on a second passage portion side, and including a third passage portion positioned between the first passage portion and the second passage portion on a free end side of the aforementioned rising and falling movement, and passing the cord through; and an urging device urging the second member in a standing direction. Also, the support point is formed by an engaging portion formed in one of the first member and the second member; and an engaged portion formed in the other of those, and engaged with the engaging portion, and the cord pulled out of the second passage portion is positioned on the free end side of the second member more than the support point.

Also, in order to obtain the aforementioned object, in a second aspect of the present invention, the cord lock comprises a first member including a first passage portion and a second passage portion for the cord; a second member combined with the first member so as to be capable of moving to rise and fall as a support point on a second passage portion side, and including a third passage portion positioned between the first passage portion and the second passage portion on a free end side of the aforementioned rising and falling movement, and passing the cord through; and an urging device urging the second member in the standing direction. Also, the first member includes side face portions and a bottom face portion, and supports the second member so as to be capable of moving to rise and fall inside the side face portions and the bottom face portion, and the second passage portion is formed across the side face portions and the bottom face portion.

Also, in order to obtain the aforementioned object, in a third aspect of the present invention, the cord lock comprises a first member including a first passage portion and a second passage portion for the cord; s second member combined with the first member so as to be capable of moving to rise and fall as a support point on a second passage portion side, and including a third passage portion positioned between the first passage portion and the second passage portion on a free end side of the aforementioned rising and falling movement, and passing the cord through; and an urging device urging the second member in the standing direction. Also, the support point is formed by an engaging portion formed in one of the first member and the second member; and an engaged portion formed in the other of those, and engaged with the engaging portion. Also, the first member includes side face portions and a bottom face portion, and supports the second member so as to be capable of moving to rise and fall inside the side face portions and the bottom face portion, and one of the engaging portion and the engaged portion is provided on a bottom face portion side of the first member.

The cord can pass through the cord lock in such a way as to be inserted from the first passage portion, and pulled out of the second passage portion through the third passage portion in a state wherein the first passage portion and the third passage portion are matched so as to pass the cord through by pushing the second member against urging of the urging device. Alternatively, the cord can pass through the cord lock in such a way as to be inserted from the second passage portion, and pulled out of the first passage portion through the third passage portion in the state wherein the first passage portion and the third passage portion are matched so as to pass the cord through by pushing the second member against the urging of the urging device. Thus, after the cord passes through the cord lock, when the pushing of the second member is stopped, the second member turns in the standing direction by the urging of the urging device so as to form a state wherein the first passage portion and the third passage portion do not match, thereby the cord lock is fastened to the cord.

In a case wherein the support point is formed by a shaft and a shaft hole, typically, in order to provide the shaft hole, a certain thickness becomes necessary for the side face portions of the first member. Also, in a case wherein the support point has a structure wherein the cord passes through, a thickness on the support point side of the cord lock cannot have a thickness of the cord or less. On the other hand, in the cord lock according to the first aspect, such support point is formed by the engaging portion and the engaged portion, and the cord pulled out of the second passage portion is positioned on the free end side of the second member more than the support point, so that the support point can be formed in such a way not to influence to the thickness and the like of the cord lock.

In the cord lock according to the second aspect, especially, the second passage portion is formed across the side face portions and the bottom face portion, so that without increasing the thickness of the first member, an area of the second passage portion can be maximized, and the cord lock can be fastened to the cord in such a way that the cord is pulled out in a direction further free from the second passage portion.

Also, if the bottom face portion of the first member is bent or curved in such a way that the support point side becomes an inside of bending or curving, in a case wherein the cord pulled out of the second passage portion functions in such a way as to narrow one portion of an article, a gap is formed between the bottom face portion of the first member positioned on the free end side of the second member and an outer face of the article, and the cord lock can be provided in such a way that the bottom face portion of the first member on the support point side is tightly attached to the outer face of the article, so that a push-in operation of the second member which releases the fastening of the cord becomes easy.

Also, if a guide wall guiding the cord inserted from one of the first passage portion and the second passage portion to the other of those, is provided, in a case wherein although the cord passing through in the cord lock as mentioned above is straight between the first passage portion and the second passage portion, the cord bends or curves at the second passage portion to be pulled out to a side; and the cord inserted from the second passage portion side can be reliably guided to the first passage portion.

In that case, in one preferred aspect, the guide wall is formed by a first guide wall formed inside the first member; and a second guide wall formed inside the second member, and forming one portion of an insertion passage for the cord together with the first guide wall in a state wherein the second member is fallen against the urging of the urging device.

Also, in one preferred aspect, on the bottom face portion of the first member, there comprises a concave portion housing the free end side of the second member so as not to form a step between the third passage portion and the bottom face portion in a state wherein the second member is operated to be pushed in against the urging of the urging device. In such a case, especially, the cord inserted from the second passage portion side can be smoothly guided to the first passage portion.

Also, in one preferred aspect, the urging device is formed by an elastically deformable portion which is one portion of the second member, and provided between the third passage portion and the support point. Also, the first member comprises a support portion abutting against the elastically deformable portion and causing the elastic deformation in the elastically deformable portion.

Also, in one preferred aspect, the urging device is formed by the elastically deformable portion which is one portion of the second member, and provided between the third passage portion and the support point. Also, the second member comprises a support portion abutting against the first member, and causing the elastic deformation in the elastically deformable portion.

Also, in one preferred aspect, the urging device is formed by the elastically deformable portion which is one portion of the second member, extends to the support point side from the third passage portion side, forms the insertion passage for the cord between the elastically deformable portion and the base plate portion of the second member, and abuts against the first member.

Effect of the Invention

According to the present invention, in an aspect wherein two members forming this type of cord lock have the least possible influences to the thickness and the like of the cord lock, the two members can be combined while securing the easiness of an operation and a degree of freedom in a shape. As a result, in the present invention, the cord lock can be easily designed so as to have the most suitable shape for a use object of the cord lock.

BEST MODES OF CARRYING OUT THE INVENTION

Hereinafter, based onFIG. 1toFIG. 37, typical embodiments of the present invention will be explained. A cord lock according to the present embodiment can be fastened to an arbitrary position of a cord R, and is formed in such a way as to release this fastening state by operating a second member2to be pushed in against urging.

Such cord R may have any shape (a round string, a flat string, and the like), any material, or any structure (a knitted string, an elastic string, a string made of synthetic resin, and the like) provided that the cord lock can be fastened in the aforementioned manner. Typically, such cord lock is fastened to the cord R in various types of articles provided with a portion which is narrowed or tightened by the aforementioned cord R, and is used in such a way as to narrow or loosen the aforementioned portion by changing a fastening position thereof.

Such cord lock comprises a first member1, a second member2, and an urging device3.

The first member1includes first passage portions4and second passage portions5of the cord R. In an example shown in the drawings, the first member1includes side face portions6and a bottom face portion7, and supports the second member2inside the side face portions6and the bottom face portion7so as to be capable of moving to rise and fall.

The second member2is combined with the first member1so as to be capable of moving to rise and fall at a support point19on the second passage portions5side, and includes third passage portions21positioned between the first passage portions4and the second passage portions5on a free end20side of the aforementioned rising and falling movement, and passing the cord R through.

The support point19is formed by an engaging portion formed in one of the first member1and the second member2; and an engaged portion formed in the other of those, and engaged with the engaging portion.

The urging device3urges the second member2in a standing direction. In the first example shown inFIG. 1toFIG. 18, a second example shown inFIG. 19, a third example shown inFIG. 20andFIG. 21, and a fourth example shown inFIG. 22andFIG. 23, such urging device3is formed by a compression coil spring28. On the other hand, in a fifth example shown inFIG. 24toFIG. 36, and a sixth example shown inFIG. 37, such urging device3is formed by one portion of the second member2.

The cord R can pass relative to the cord lock in such a way as to be inserted from the first passage portion4and be pulled out of the second passage portion5through the third passage portion21in a state wherein the first passage portion4and the third passage portion21are matched so as to be capable of passing the cord R by pushing the second member2against the urging of the urging device3. Alternatively, the cord R can pass relative to the cord lock in such a way as to be inserted from the second passage portion5and be pulled out of the first passage portion4through the third passage portion21in the state wherein the first passage portion4and the third passage portion21are matched so as to be capable of passing the cord R through by pushing the second member2against the urging of the urging device3. Thus, after the cord R passes through the cord lock, when the pushing of the second member2is stopped, the second member2turns in the standing direction by the urging of the urging device3so as to have a state wherein the first passage portion4and the third passage portion21do not match, thereby the cord lock is fastened to the cord R. Incidentally, the pushing of the second member2includes a case wherein such second member2is relatively pushed in as well.

In a case wherein the support point19is formed by a shaft and a shaft hole, typically, in order to provide the shaft hole, a certain thickness becomes necessary for the side face portion6of the first member1. Also, in a case wherein the support point19is formed in such a way as to pass the cord R through, a thickness on the support point19side of the cord lock cannot have a thickness of the cord R or less. On the other hand, in the cord lock according to the present embodiment, such support point19is formed by the engaging portion and the engaged portion, and the cord R pulled out of the second passage portion5is positioned on the free end20side of the second member2more than the support point19, so that the support point19can be formed in such a way not to influence to the thickness and the like of the cord lock.

More specifically, in the first example to the fourth example, the engaging portion is formed by an engagement claw22, and the engaged portion is formed by an engagement hole8with which the engagement claw22is engaged.

At least one portion of the second passage portion5is positioned on the free end20side of the second member2more than the support point19. Thereby, in the cord lock according to the present embodiment, in a state wherein although the cord R passing through in the cord lock as mentioned above is straight between the first passage portion4and the second passage portion5, the cord R bends or curves at the second passage portion5to be pulled out to a side just in front (the free end20side) more than the support point19, and the cord lock can be fastened to such cord R (FIG. 12).

Also, in the first example shown inFIG. 1toFIG. 18, the second example shown inFIG. 19, and the third example shown inFIG. 20andFIG. 21, the second passage portion5is formed across the side face portion6and the bottom face portion7. Thereby, in the first example to the third example, moreover, without increasing the thickness of the first member1, an area of the second passage portion5can be maximized, and the cord lock can be fastened to the cord R in such a way that the cord R is pulled out further in a free direction from the second passage portion5.

Also, the cord lock according to the first example to the third example bends or curves at the bottom face portion7of the first member1in such a way that the support point19side becomes an inside of bending or curving. In such a case, in a case wherein the cord R pulled out of the second passage portion5functions in such a way as to narrow one portion of an article, a gap S is formed between the bottom face portion7of the first member1positioned on the free end20side of the second member2and an outer face of the article, and the cord lock can be provided in such article in such a way that the bottom face portion7of the first member1on the support point19side is tightly attached to the outer face of the article, so that a push-in operation of the second member2which releases the fastening of the cord R becomes easy. For example, as shown inFIG. 11, the cord lock can be fastened to the cord R narrowing an opening Ga of a glove G in a state of forming the gap S between the bottom face portion7of the first member1positioned on the free end20side of the second member2and an outer face on an opening Ga side of the glove G.

Also, the cord lock according to the first example to the third example comprises a guide wall guiding the cord R inserted from one of the first passage portion4and the second passage portion5to the other of those. In such a case, in a case wherein although the cord R passing through in the cord lock as mentioned above is straight between the first passage portion4and the second passage portion5, the cord R bends or curves at the second passage portion5to be pulled out to the side; the cord R inserted from the second passage portion5side can be reliably guided to the first passage portion4.

More specifically, in the cord lock according to the first example to the third example, the guide wall is formed by first guide walls9(for example, seeFIG. 15regarding the first example) formed inside the first member1; and second guide walls23formed inside the second member2, and forming one portion of an insertion passage of the cord R together with the first guide walls9in a state wherein the second member2falls against the urging of the urging device3.

Also, in the cord lock according to the first example to the third example, on the bottom face portion7of the first member1, in a state wherein the second member2is operated to be pushed in against the urging of the urging device3, there comprises a concave portion7ahousing the free end20side of the second member2so as not to generate a step between the third passage portion21and the bottom face portion7(for example, seeFIG. 9andFIG. 10regarding the first example). In such a case, especially, the cord R inserted from the second passage portion5side can be smoothly guided to the first passage portion4.

First Example

The cord lock of the first example shown inFIG. 1toFIG. 18has a structure comprising a length and a width. In the first example, the cord R passes respectively on a left side and a right side sandwiching a virtual center line L1(FIG. 12andFIG. 15) passing a position of an approximately middle in a width direction of the cord lock.

Specifically, in the example shown in the drawings, one terminal side of the cord R narrowing the opening Ga of the glove G is pulled out of the first passage portion4on the left side through the second passage portion5on the left side sandwiching the center line L1of the cord lock, and the other terminal side of the cord R narrowing the opening Ga of the glove G is pulled out of the first passage portion4on the right side through the second passage portion5on the right side sandwiching the center line L1of the cord lock (FIG. 12).

The first member1comprises the bottom face portion7forming a plate shape; a pair of length-direction side face portions6forming a wall shape rising from edge portions in a length direction of such bottom face portion7along a length direction of the cord lock; and a pair of width-direction side face portions6forming the wall shape rising from the edge portions in a width direction of the bottom face portion7along the width direction of the cord lock, and the first member1opens a side facing the bottom face portion7(seeFIG. 1andFIG. 2).

The bottom face portion7curves such that the open side becomes a curvature inside in the length direction of the cord lock.

In one of the pair of width-direction side face portions6of the first member1(hereinafter, called a front-side side face portion6a), there is formed the first passage portion4substantially having a square hole shape.

The second passage portions5are respectively formed on both sides sandwiching the center line L1between a virtual first width-direction line segment L2(seeFIG. 15) orthogonal to the center line L1at a position of an approximately middle in the length direction of the cord lock, and the other of the pair of width-direction side face portions6(hereinafter, called a back-side side face portion6b). The second passage portion5is formed by a first hole portion5asubstantially having a square shape passing through the bottom face portion7between the later-described first guide wall9and the length-direction side face portion6; and a second hole portion5bnotching the side face portion6in a mountain shape, and communicating with the first hole portion5aon a base portion side thereof. The second passage portion5is formed across the bottom face portion7and the side face portion6, and the cord R can be pulled out toward an outside (a direction inFIG. 1) of the bottom face portion7of the first member1through the second passage portion5, and additionally, toward a side (b direction inFIG. 1) of the side face portion6as well.

On an outside of the back-side side face portion6b, there is disposed a wrapping bar10for a belt-shaped member T (seeFIG. 12) in a state wherein an insertion gap11of the belt-shaped member T is formed between the wrapping bar10and the back-side side face portion6b(seeFIG. 7). The wrapping bar10is disposed between extension portions6cand6cof the pair of length-direction side face portions6and6projecting backwardly more than the back-side side face portion6b.

Thereby, in the first example, the cord lock can be attached relative to the article wherein the cord R is provided using the belt-shaped member T wrapped in the wrapping bar10through the insertion gap11in such a way that the article and the cord lock do not separate even in a state wherein the cord R is not inserted to pass through.

Also, the first guide wall9along a virtual left-side length-direction line segment L3(seeFIG. 15) parallel to the center line L1is formed between the center line L1and the length-direction side face portion6on the left side. Also, the first guide wall9along a virtual right-side length-direction line segment L4(seeFIG. 15) parallel to the center line L1is formed between the center line L1and the length-direction side face portion6on the right side. Those first guide walls9are formed throughout between the back-side side face portion6band the first width-direction line segment L2.

Also, a slit12along the width direction of the cord lock is formed along an inner face of the back-side side face portion6bbetween the right and left first guide walls9and9(seeFIG. 7andFIG. 15). Also, at the position of the approximately middle in the width direction of the cord lock in the back-side side face portion6b, a notched portion14notching the back-side side face portion6bis formed in such a way as to form a bridge portion13on a curvature inside of the bottom face portion7, and the slit12and the notched portion14are communicated (seeFIG. 7). In the example shown in the drawing, the engagement claw22of the second member2enters into the notched portion14, and engages the bridge portion13. Namely, in the example shown in the drawing, the notched portion14becomes the engagement hole8functioning as the engaged portion.

The bottom face portion7divides between the first width-direction line segment L2and the front-side side face portion6a, and an inner face between a virtual second width-direction line segment L5(seeFIG. 15) parallel to the first width-direction line segment L2and the front-side side face portion6ais lower than an inner face between the second width-direction line segment L5and the second passage portion5. Thereby, the first member1comprises the concave portion7aon a front-side side face portion6aside (seeFIG. 9).

On an inner face of the bottom face portion7, between the second width-direction line segment L5and the front-side side face portion6a, and on the center line L1, there is formed a projection7bwhich can be housed inside one end of the compression coil spring28as the urging device3(seeFIG. 7).

The second member2includes the front-side side face portion6aand the back-side side face portion6bof the first member1; and a base plate portion2asurrounded by the length-direction side face portions6on the right and left, and having a shape matching an inner outline shape of an open portion of the first member1(seeFIG. 16). The second member also comprises the width and the length. Also, the base plate portion2aof the second member2comprises a curvature following a curvature of the base plate portion2aof the first member1.

On the free end20side of the second member2, there is formed an enlarged portion24projecting toward the bottom face portion7side of the first member1. The enlarged portion24is formed throughout the width direction of the second member2.

On the right and left sandwiching the center line L1(seeFIG. 12andFIG. 18), there are respectively formed the third passage portions21. Such third passage portion21has a tunnel shape continuing in a direction along the center line L1, and passes through the enlarged portion24(seeFIG. 16).

Between the third passage portions21on the right and left, and in the enlarged portion24, there is formed a bottomed hole25in which the compression coil spring28as the urging device3can be housed, and the other end of such spring28abuts against a bottom of the bottomed hole25(seeFIG. 17).

Also, on an inner face of the base plate portion2aof the second member2, there are formed the second guide walls23forming the guide walls together with the first guide walls9of the first member1respectively on the right and left sandwiching the center line L1(seeFIG. 17). The second guide wall23is formed throughout between the enlarged portion24and a position of an approximately middle in the length direction of the second member2in such a way as to continue to a hole wall on the center line L1side of the third passage portion21.

On the support point19side of the second member2, there is formed the engagement claw22which becomes the engaging portion (seeFIG. 17). The engagement claw22is formed by a projection22bprojecting to a side opposite to the enlarged portion24formed at a tip of an elastic leg22aprojecting from the inner face of the base plate portion2aon the center line L1.

Also, at a projecting end of the enlarged portion24, and on a side opposite to the support point19side, there are formed retainer projections27which are caught on the first passage portions4inside the first member1(seeFIG. 16).

The first member1and the second member2are combined by one-touch operation by pushing the second member2into the first member1while interposing the spring28between the first member1and the second member2using the bottomed hole25and the projection7b. Namely, by the engagement claw22pressed against the bridge portion13by the aforementioned pushing, the bridge portion13and the elastic leg22acause an elastic deformation once to allow the engagement claw22to climb over the bridge portion13, thereby, when the engagement claw22enters into the notched portion14, the engagement claw22engages the bridge portion13by an elastic return, and the second member2is combined relative to the first member1so as to be capable of moving to rise and fall at the engagement portion as the support point19.

In a state wherein the cord R does not pass, the second member2is positioned at a standing position where the retainer projection27is caught on the hole wall positioned on a projecting end side of the side face portion6of the first passage portion4by the urging of the urging device3. In that state, the first passage portion4and the third passage portion21do not match, and the cord R cannot pass through the cord lock (FIG. 9). When the cord lock is pinched on the free end20side in such a way as to push the free end20side of the second member2against the urging, the enlarged portion24enters into the concave portion7ainside the cord lock, and the first passage portion4and the third passage portion21match so as not to form the step between the bottom face portion7and the third passage portion21. Also, the first guide wall9and the second guide wall23continue by opening a slight gap, and an insertion passage for the tube-shaped cord R is formed between the first passage portion4and the second passage portion5(FIG. 8andFIG. 10). Thereby, the cord R can smoothly pass through from the first passage portion4toward the second passage portion5. Also, conversely, the cord R can smoothly pass through from the second passage portion5toward the first passage portion4as well. After the cord R passes through, when the pushing of the second member2is stopped, the second member2turns in a direction of separating the free end20side from the bottom face portion7of the first member1around the support point19by the urging, and an opening edge of the first passage portion4and an opening edge of the third passage portion21respectively bite relative to the cord R passing through by the aforementioned turning, so that the cord lock is fastened to the cord R.

Second Example

The cord lock of the second example shown inFIG. 19bends in such a way that the bottom face portion7of the first member1forms a top portion15at the back of the support point19. Since the rest of a structure of the second example is substantially the same as that of the first example, the same symbols used in the first example are assigned to the drawings showing the second example, and their explanations are omitted.

Third Example

In the cord lock of the third example shown inFIG. 20andFIG. 21, the first member1comprises a hook portion16outside the back-side side face portion6b. In such hook portion16, one end of a belt-shaped curvature piece having a U-shaped cross-sectional shape is integrally connected to an outer face of the back-side side face portion6b. An open end17of the hook portion16is positioned on an open side of the first member1. Since the rest of a structure of the third example is substantially the same as that of the first example, the same symbols used in the first example are assigned to the drawings showing the third example, and their explanations are omitted.

Fourth Example

In the cord lock of the fourth example shown inFIG. 22andFIG. 23, the first member1comprises fin-shaped portions18wherein one face thereof continues to an outer face of the bottom face portion7outside the length-direction side face portions6on the right and left. In the fourth example, using the fin-shaped portions18, the cord lock can be sewn to a cloth forming clothes, pouches, and the like. In the fourth example, the second passage portion5is formed only in the bottom face portion7. Also, the engaging portion and the engaged portion are provided at two portions on the right and left. Since the rest of a structure of the fourth example is substantially the same as that of the first example, the same symbols used in the first example are assigned to the drawings showing the fourth example, and their explanations are omitted.

Fifth Example

In the cord lock of the fifth example shown inFIG. 24toFIG. 36, the urging device3is formed by an elastically deformable portion f which is one portion of the second member2, and provided between the third passage portion5and the support point19. Also, the first member1comprises a support portion29abutting against the elastically deformable portion f to cause the elastic deformation in the elastically deformable portion f (seeFIG. 26andFIG. 27).

In the example shown in the drawings, the cord lock of the fifth example has a structure comprising the length and the width. In the fifth example, one cord R (in the drawings showing the fifth example, the cord R is omitted) passes through the cord lock along a virtual center line z (FIG. 24andFIG. 29) passing the position of the approximately middle in the width direction of the cord lock.

In the cord lock of the fifth example, the first member1includes the bottom face portion7having the length and the width; side face portions6dand6din the length direction positioned on the right and left sandwiching the virtual center line z; and side face portions6eand6ein the width direction at two portions, and has a structure wherein a side opposite to the bottom face portion7is open. The example shown in the drawings has a structure wherein a rising size of the side face portion6ein the width direction positioned on the left side inFIG. 26is larger than a rising size of the side face portion6ein the width direction positioned on the right side, and a projecting size of the side face portion6din the length direction from the bottom face portion7is gradually reduced toward the right side from the left side inFIG. 26. In the example shown in the drawings, respectively on the left side and the right side inFIG. 26, the first member1further comprises a tongue piece portion30projecting outwardly from a base portion of the side face portion6ein the width direction in such a way that one face thereof is positioned on the same face as an inner face7cof the bottom face portion7, and the other face thereof is positioned on the same face as the outer face7bof the bottom face portion7. In this example, using such tongue piece portion30, the cord lock can be fixed to a use object of the cord lock by sewing, welding, and the like. The first passage portion4is formed in such a way as to pass through an inside and an outside of the side face portion6ein the width direction positioned on the left side inFIG. 26. Incidentally, in the example shown in the drawing, a square through-hole31is formed in the bottom face portion7at a position directly under the first passage portion4. On the other hand, the second passage portion5is formed in such a way as to pass through a position on the virtual center line z in the bottom face portion7on the right side inFIG. 26(FIG. 29). A through-hole32larger than the second passage portion5is formed between the second passage portion5and the side face portion6ein the width direction positioned on the right side inFIG. 26(FIG. 29). The through-hole32and the second passage portion5are communicated by a communication hole33gradually reducing a hole width as moving near the second passage portion5side. Also, a projecting portion34projecting inwardly from an inner face of the side face portion6ein the width direction is formed directly above the through-hole32, and in the example, such projecting portion34functions as the engaged portion. Also, in the example, the support portion29is formed between a position of an approximately middle in the length direction of the first member1and the second passage portion5. In the example, the support portion29is respectively provided on the right and left sandwiching the virtual center line z. The support portions29and29on the right and left respectively have a column shape wherein a lower end is integrated with the bottom face portion7, and one portion of a side portion is integrated with an inner face of the side face portion6din the length direction, and a gap through which the cord R passes is formed between the support portions29and29on the right and left (seeFIG. 32).

On the other hand, in the cord lock of the fifth example, the second member2comprises a base plate portion35having the length and the width; the third passage portion21; an inside plate portion36; and the engaging portion (for example, the later-described tongue piece38). The base plate portion35has an outline shape which can be complementarily housed inside a space surrounded by four side face portions6d. . .6eof the first member1. One face35aof the base plate portion35forms an outer face of the cord lock. The inside plate portion36is shorter than the base plate portion35, and has a size which can be housed in the space inside the first member1. The inside plate portion36and the base plate portion35are integrated in such a way as to open an interval passing the cord R through between the inside plate portion36and the base plate portion35through a connection portion37on the free end20side of the second member2. The third passage portion21is formed such that the connection portion37passes through in a direction along the length direction of the second member2. The engaging portion is formed by the tongue piece38projecting in such a way as to form a step38aon one face side of the base plate portion35on the support point19side of the second member2of the base plate portion35.

Although a distance from a free end35bof the base plate portion35which becomes the free end20of the second member2to the step38ais substantially equal to a distance between the side face portions6eand6ein the width direction of the two portions of the first member1, a distance between the free end20and a tip of the tongue piece38is larger than that. In the example shown in the drawings, the tongue piece which becomes the engaging portion is housed below the projecting portion34which becomes the engaged portion, so that the first member1and the second member2are combined by a portion where the projecting portion34and the tongue piece38contact with each other as the support point19. Also, in this combined state, a projecting end36aside of the inside plate portion36abuts against the bottom face portion7of the first member1between the first passage portion4and the support portion29. In the example shown in the drawings, in the free end20of the second member and below an entrance of the third passage portion5, more specifically, in an entrance of the third passage portion21and a connection portion side between the connection portion37and the inside plate portion36, there is formed a claw portion39. Then, the combined state between the first member1and the second member2is maintained by catching the claw portion39on the inner face positioned at a projecting end side of the side face portion6ein the width direction in the first passage portion4(FIG. 26). Specifically, from a state wherein the tongue piece38which becomes the engaging portion is housed below the projecting portion34which becomes the engaged portion, when the free end20side of the second member2is pushed into the space of the first member1, the claw portion39abuts against a projecting end of the side face portion6ein the width direction so as to cause the elastic deformation mainly on a first member1side, and to allow the pushing which allows the claw portion39to enter into the first passage portion4, and by the elastic return after that, the claw portion39is caught on an inner face of the first passage portion4. Then, in the combined state as mentioned above, the inside plate portion36causes the elastic deformation in a direction of narrowing a distance between the inside plate portion36and the base plate portion (FIG. 26). In that state, the first passage portion4and the third passage portion21do not match (FIG. 26). When the free end20of the second member2is operated to be pushed, a portion positioned on the free end20side more than the support portion29in the base plate portion35is elastically deformed such that the support portion29is a deformation center so as to generate a state wherein the first passage portion4and the third passage portion21match. In that matching state, the cord R can be inserted into the cord lock through the first passage portion4, the second passage portion5, and the third passage portion21. After the cord R is inserted to pass through, when the push-in operation of the second member2is stopped, the base plate portion35and the inside plate portion36are elastically returned, and the second member2moves in a direction where the first passage portion4and the third passage portion21are mismatched, so that the cord lock is fastened to the cord R by an urging force of such elastic return.

Namely, in the cord lock of the fifth example, the urging device3as a separate member is not required as in the case of the cord lock of the first example to the fourth example. In the cord lock of the fifth example, the urging device3is formed by the inside plate portion36as the elastically deformable portion f which is one portion of the second member2, extends to the support point19side from the third passage portion21side, forms the insertion passage for the cord R between the inside plate portion36and the base plate portion35of the second member2, and abuts against the first member1; and the base plate portion35.

Incidentally, the urging device3can be formed only by the inside plate portion36, and the base plate portion35can be formed without the elastically deformable portion f as well, and in that case, the support portion29becomes unnecessary.

Sixth Example

In the cord lock of the sixth example shown inFIG. 37, the urging device3is formed by the elastically deformable portion f which is one portion of the second member2, and provided between the third passage portion21and the support point19. Also, the second member2comprises a support portion40causing the elastic deformation in the elastically deformable portion f by abutting against the first member1. In the example shown in the drawing, the support portion40is formed on the other face35cfacing the bottom face portion7of the first member1in the base plate portion35of the second member2; between the third passage portion21and the support point19; and on the support point19side more than the inside plate portion36. Such support portion40is provided respectively on the right and left sandwiching the virtual center line z. The support portions40and40on the right and left respectively have a column shape wherein an upper end is integrated with an inner face of the base plate portion35, and a gap through which the cord passes is formed between the support portions40and40on the right and left.

Since the rest of a structure of the sixth example is substantially the same as that of the fifth example including the first example, the same symbols used in the first example are assigned to the drawing showing the fifth example asFIG. 37, and their explanations are omitted.

An elastic deformation characteristic can be easily provided to a portion which should comprise the aforementioned characteristic in the cord lock of each example explained in the above by making the first member1and the second member2as a plastic molded article.

Incidentally, obviously, the present invention is not limited to the embodiments explained hereinabove, and includes all embodiments which can obtain the object of the present invention.
