Japanese Unexamined Patent Publication No. 2004-2428889

In a binding device with a closed loop structure that is used to bundle and hold keys, etc., such as a key chain or key ring, it is necessary to safely store and hold the managed keys, so the keys, etc. are temporarily held in a closed loop. When closed in a shape, it may be preferable that the structure is such that the key or the like cannot be easily opened and removed. With such a highly safe structure, for example, if the key or the like is held by the binding tool of the structure and left to the management staff, the management staff may remove the key or the like from the binding tool for some reason. Even if you try to remove it, the binding tool cannot be released due to its structure, and there is no risk that the key or the like will be removed from the binding tool. However, in the inventions of conventional binding devices such as Patent Document 1, no one that effectively solves such a problem has been known.

An object of the present invention is to solve the problems in the prior art described above, and to provide a binding tool capable of holding valuable articles such as keys in a closed loop structure and a reliable locking structure capable of holding the closed loop structure. It is intended to provide a highly safe binding tool that cannot easily release the closed loop structure of the key even if the key or the like is to be removed.

The binding tool according to claim 1 is
It has a receptor, a flexible long body having one end connected to the receptor, and an insert provided at the other end of the free end of the long body, and the insert is referred to as the acceptor. In a binding tool that is inserted into and irremovably engaged
A cover portion formed on either one of the receptor and the insert and covering the contact surface where the receptor and the insert are in contact with each other so as not to be visible from the outside when the receptor and the insert are engaged with each other. Yes, and
The binding tool becomes annular when the receptor and the insert are engaged with each other.
The insert has a protrusion having a direction intersecting the surface containing the ring as the insertion direction with respect to the receptor.
The receptor has a receiving portion that engages with the inserted protrusion.
The cover portion is characterized in that it is formed at a predetermined position of at least one of the receptor and the insert body, which makes the gap of the contact surface created by bending the long body invisible from the outside. There is.

The binding tool according to claim 2 is the binding tool according to claim 1 .
A convex portion provided on one of the receptor and the insert,
A hole provided on the other side of the receptor and the insert and fitted with the convex portion,
It is characterized by having.

According to the binding device according to claim 1, even if a tool such as a driver is inserted from the outside into the contact surface between the acceptor and the inserter in the engaged state, the cover portion interferes with the contact surface. It is possible to reliably prevent the engagement state between the body and the insert body from being illegally released. Further, even if a gap is provided on the contact surface by separating the insert and the receptor by bending the long body in the insertion direction and a tool such as a screwdriver is inserted there, the cover portion creates a gap on the contact surface. Since it is covered, it interferes with such an act, so that it is possible to reliably prevent the engagement state from being illegally released.

According to the binding device according to claim 2 , when the receptor and the insert are engaged, the engagement point at which the receptor and the insert are fixed to each other is the protrusion of the receiver and the insert. There are two points, a portion where the portion engages and a portion where the convex portion and the hole portion fit. In this way, the acceptor and the inserter in the engaged state are held in a fixed state at two points, so that a gap is formed in the contact surface between the inserter and the acceptor by bending the long body in the insertion direction or the like. It is possible to make it difficult to perform the operation that causes the above.

It is a perspective view which showed the binding tool of 1st Embodiment in an open state with the side of the entrance of the receptor into which an insert body is inserted as the front side. FIG. 3 is a perspective view showing the binding device of the first embodiment in which an insert is engaged with a receptor to form a closed loop, with the side of the entrance of the receptor into which the insert is inserted as the front side. FIG. 3 is a schematic cross-sectional view taken along the line AA of FIG. 2. FIG. 5 is a schematic cross-sectional view of the binding tool of the second embodiment at a position equivalent to the AA cutting line of FIG. 2 in the first embodiment.

The first embodiment of the present invention will be described with reference to FIGS. 1 to 3.
The outline of the binding tool 1 of the first embodiment will be described with reference to FIGS. 1 and 2.
The binding tool 1 of the first embodiment is a tool used for holding valuable items such as one or two or more keys, such as a normal key chain or a key ring. Once the binding tool 1 is closed in a closed loop shape while holding a key or the like, the state is firmly fixed, and either manual operation or operation using an instrument can be used by any method. However, it has a highly safe structure that cannot be easily opened and the holding key or the like cannot be easily removed.

As shown in FIGS. 1 and 2, the binding tool 1 has a substantially cylindrical receptor 2 and a flexible length having one end connected to the side peripheral surface of the receptor 2 and flexed in a substantially circular shape. It has a body 3 and an inserter 4 provided at the other end, which is the free end of the long body 3. Each of these parts is integrally composed of elastic resin as a material, but each part is made a separate part, and only the parts that require elastic deformation, such as the long body 3, and the parts are made of elastic material such as resin. You may assemble it.

The details will be described later, but as shown in FIG. 1, in the binding tool 1 in the state where the long body 3 is open, the long body is formed in the key ring hole provided in the head of the key or the like or the annular portion 5 of the strap inserted into the key ring hole. 3 is inserted, and as shown in FIG. 2, the insert 4 is inserted into the receptor 2 and engaged to form a closed loop ring, and a key or the like (not shown) is held by the bundling tool 1. Can be done.

The details of the engagement structure provided on the receptor 2 and the insert 4 will be described with reference to FIG.
The insert 4 has a protrusion 6 on the lower surface on the distal end side thereof. The protruding portion 6 has an insertion direction with respect to the receptor 2 in a direction intersecting the plane including the annular oblong body 3 (downward in the vertical direction in FIG. 3). At the lower end of the protrusion 6, a first locking protrusion 7 facing the tip side is provided. Further, the insert body 4 has a convex portion 8 on the lower surface on the rear end side. The insertion direction of the convex portion 8 with respect to the receptor 2 is the same as that of the protruding portion 6. At the lower end of the convex portion 8, a second locking projection 9 projecting in the direction opposite to that of the first locking projection 7 of the protruding portion 6 is provided.

As shown in FIG. 3, the receptor 2 has a receiving portion 10 that engages with a protruding portion 6 of the insert 4. The receiving portion 10 is formed on the insertion hole 11 into which the protrusion 6 is inserted and on the inner surface of the insertion hole 11 on the long body 3 side, and is in the direction opposite to the first locking protrusion 7 of the protrusion 6 of the insertion body 4. It has a first locking portion 12 directed to. Further, the receptor 2 has a hole 13 on the side opposite to the long body 3 side. A second locking portion 14 is provided on the inner surface of the hole portion 13 so as to be directed in the direction opposite to the second locking projection 9 of the convex portion 8 of the insertion body 4.

As shown in FIG. 3, a cover portion 15 extending toward the receptor 2 side from the connection position with the long body 3 is provided on the end surface of the insert body 4 on the long body 3 side. The cover portion 15 covers the contact surface 20 (indicated by a broken line in FIG. 3) in which the receptor 2 and the insert 4 are in contact with each other so as not to be visible from the outside when the receptor 2 and the insert 4 are engaged with each other. be able to. As shown in FIG. 1, the contact surface 20 has a concave surface having a substantially cylindrical shape of the receptor 2 that is partially cut out to match the shape of the insert body 4, and the receptor 2 and the insertion surface 20. It is composed of a convex surface in which the insertion body 4 is in contact with the concave surface in a state where the body 4 is engaged. The concave surface of the receptor 2 functions as a guide portion for guiding when the insert body 4 is engaged, and the convex surface on the insert body 4 side functions as a guided portion guided by the guide portion.

The procedure for holding the key in the binding tool 1 of the first embodiment will be described.
First, as shown in FIG. 1, the insert body 4 and the long body 3 are inserted through the annular portion 5 of the strap inserted into the ring hole of the key. As shown in FIG. 1, in the state where the insert 4 is not engaged with the receptor 2 and the long body 3 is still open, the long body 3 has a shape slightly enlarged from the circular shape. There is sufficient clearance between the insert 4 and the receptor 2. Therefore, the operation of inserting the annular portion 5 of the strap into the long body 3 can be easily performed.

Next, as shown in FIG. 2, the inserter 4 at the tip of the oblong body 3 is inserted into the fitting structure of the acceptor 2 while bending the oblong body 3 in a direction of contracting the oblong body 3 so as to have a shape close to a circle. , The whole is a closed loop ring. As a result, it is possible to hold a key (not shown) in the closed ring-shaped binding tool 1.

Then, in the state where the insert 4 and the accept 2 are engaged with each other in this way, the accept 2 and the insert 4 are fixed to each other at two points.
The first portion is a portion where the receiving portion 10 of the receptor 2 and the protruding portion 6 of the insert 4 are engaged with each other. Here, the protrusion 6 of the insert 4 is inserted into the insertion hole 11 of the receiving portion 10 of the receptor 2, and the first locking projection 7 of the protrusion 6 is the first engagement of the insertion hole 11 of the receiving portion 10. Overcoming the stop 12 and engaging with each other.

The second portion is a portion where the hole portion 13 of the receptor 2 and the convex portion 8 of the insert body 4 are engaged with each other. Here, the convex portion 8 of the insert 4 is inserted into the hole 13 of the receptor 2, and the second locking projection 9 of the convex portion 8 presses the second locking portion 14 of the hole 13 of the receiving portion 10. Overcoming, the two are engaged to each other.

In this way, the acceptor 2 and the insert 4 in the engaged state are engaged with each other in a state in which they cannot be pulled out due to the protrusion structure that meshes with each other at two positions, and are securely held in the fixed state. Looking at the engaging structure of the protrusion structure at these two locations, as can be seen from FIG. 3, the protruding direction of the first locking protrusion 7 and the protruding direction of the second locking protrusion 9 are opposite to each other. Therefore, even if an external force is applied to the insertion body 3 in an attempt to disengage the engagement, the disengaging action on the first locking projection 7 and the second locking projection 9 does not work in the same direction, and one of them is in the disengaging direction. If it moves to, the other moves in a direction in which the locking becomes stronger, so that it is difficult to disengage. Therefore, an attempt to remove the insert 4 from the receptor 2 in order to remove the key from the annular bundling tool 1 is futile. The insert 4 cannot be removed from the receptor 2 even if an external force is applied to the long body 3 to bend it in various directions. In order to remove the annular portion 5 from the ring-shaped long body 3, it is necessary to break the engagement structure between the insert 4 and the receptor 2 or cut the long body 3.

In particular, as shown in FIG. 2, the long body 3 of the binding tool 1 has a shape slightly larger than the circular shape at the time of engagement in the open state before locking, but is smaller than this. By engaging the insert 4 with the fitting structure of the receptor 2 in a state of being bent so as to be circular, a closed loop is formed. Therefore, a force that elastically returns to the original larger circle acts on the circular oblong body 3 after engagement. Therefore, since this force is always applied to the two positions where the receptor 2 and the insert 4 are engaged, in addition to the two positions as described above, this action is also applied. Also, these engaged states are more difficult to disengage.

Further, according to the binding tool 1 of the first embodiment, the contact surface 20 between the receptor 2 and the insert body 4 shown by the arrow in the broken line in FIG. 3 is provided by the cover portion 15 provided on the insert body 4. It is protected so that it cannot be seen from the outside. Therefore, a tool such as a driver is inserted from the outside into the gap of the contact surface 20 provided so that the insertion body 4 and the receptor 2 are separated from each other by bending the contact surface 20 or the long body 3 in the insertion direction. Even if the body 4 is to be removed from the receptor 2, the cover portion 15 interferes with the operation, so that the engagement state between the receptor 2 and the insert 4 can be reliably prevented from being illegally released.

In the first embodiment described above, the unevenness or the relationship between the male and the female in the engaging structure of the receptor 2 and the insert 4 may be reversed. For example, in the first embodiment, the side having the receiving portion 10 is referred to as a receptor 2, the receptor 2 is provided with a hole 13 as a second engaging structure, and the side having the protruding portion 6 is an inserter 4. Although the insertion body 4 is provided with the convex portion 8 as the second engaging structure, the hole portion 13 of the receptor 2 may be a convex portion and the convex portion 8 of the insert body 4 may be a hole portion.

A second embodiment of the present invention will be described with reference to FIG.
In the first embodiment, the cover portion 15 that hides the contact surface 20 between the receptor 2 and the insert body 4 is provided on the end surface of the insert body 4 on the long body 3 side. On the other hand, as shown in FIG. 4, in the binding tool 1'of the second embodiment, the cover portion 25 has the end face of the insert body 4 opposite to the connecting portion of the long body 3 of the receptor 2. It is provided by extending toward the long body 3.

Even with such a structure, the contact surface 20 between the receptor 2 and the insert 4 shown by the dashed arrow in FIG. 4 is protected from the outside by the cover portion 15 provided on the receptor 2. be able to. Then, as in the first embodiment, a tool such as a driver is inserted from the outside into the gap between the contact surface 20'or the contact surface 20'provided with the insert 4 and the receptor 2 separated from each other, and the insert 4 is inserted. Is removed from the receptor 2 and the engagement state between the receptor 2 and the insert 4 can be reliably prevented from being illegally released.

The other structures in the second embodiment are substantially the same as those in the first embodiment. In FIG. 4 showing the second embodiment, the same reference numerals are given to the parts corresponding to FIG. 3 of the first embodiment, and the corresponding parts of the first embodiment are described in the description of the second embodiment regarding the same parts. The explanation of is used.

The binding tools 1, 1'of each embodiment described above have been described as being used for bundling and holding keys and the like like a key chain or a key ring, but of course, the objects to be held by the binding tools 1, 1'. Is not limited to the key, and it is natural that any article that can insert and hold the long body 3 can be a target.
