A clip in which a clip piece is attached to a clip body via a support shaft so that the clip piece can be freely opened and closed, and the clip piece is biased by a biasing means such as a torsion coil spring so that the clamping portion of the clip piece is closed. There has been provided a clip which can prevent the holding piece from being opened by holding a lock pin between the holding piece and the operation portion (see, for example, Patent Document 1).
JP 2003-39120 A

  Since the conventional clip uses a lock pin so that the holding piece does not open unnecessarily, there is a merit that even if an infant operates the clip, there is no possibility that a finger will be pinched accidentally. However, the lock pin cannot be used in a state where the clip is used, that is, in a state where some article is sandwiched, and in this state, the clip may be opened by mistake. In this case, the sandwiched article falls, or the clip itself falls and cannot perform its intended use.

  Then, an object of this invention is to provide the clip which can restrict | limit open | release even in the state which pinched | interposed the article | item.

  The present invention solves the above-described problems by the following means. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

The clip of the present invention is attached to the first holding member (2) and the first holding member through a support shaft (3) so as to be swingable. A second clamping member (4) in which a clamping part (21) that is opened and closed with respect to one clamping member is provided, and an operation part (22) that is operated to open and close the clamping part is provided on the other end side. And an urging means (25) for urging the second clamping member around the spindle so that the clamping part of the second clamping member is closed with respect to the first clamping member; An opening restricting member that is disposed between the first holding member and the operation portion of the second holding member and restricts an opening amount of the holding portion of the second holding member with respect to the first holding member ( 30), and the opening restricting member is located at a maximum restricting position closest to the support shaft, from the support shaft. Minimum limiting position even distant, and attached to the first or second holding member capable of holding the state in each of the at least one middle limiting position between those maximum limit position and a minimum limit position, said first One of the first and second clamping members is provided with a pair of support walls (10) extending in a position adjustment direction connecting the maximum restriction position and the minimum restriction position. Guide portions (16) extending in the position adjustment direction are provided, the opening restriction member is supported by a support member (31) spanned between the guide portions, and the guide portion receives at least the support member. Three concave portions (16b) are provided along the position adjustment direction, and the portion of the first or second clamping member that is in contact with the opening limiting member of the other clamping member has a front The Rukoto is abutting portion as the stepwise height decreases away from the support shaft along a positioning direction (24) is provided, to solve the problems described above.

According to the clip, and restrained in a state where the clamping member is completely closed at the maximum limit position, also a clamping member with minimal restriction position as provided opening limiting member as well open, the opening limiting member midway By holding in the restricting position, it is possible to prevent the subsequent opening operation in a state where the holding member is somewhat opened. For this reason, it becomes possible to restrict | release opening of a clamping member also in the state which has pinched | interposed the goods. In addition, by changing the recess for receiving the support member, the position of the opening restriction member can be selectively changed among the maximum restriction position, the minimum restriction position, and the midway restriction position. In addition, by providing such an abutting portion, the adjustment range of the opening amount of the clip can be further increased by bringing a surface having a different abutting portion height into contact with the opening restricting member in response to a change in the position of the opening restricting member. It becomes possible to take large.

  In the clip of the present invention, at least one midway limit position is sufficient, but it is desirable to provide as many midway limit positions as possible within a possible range. In addition, when the holding position of the opening restriction member can be continuously changed between the maximum restriction position and the minimum restriction position, it is included in one aspect of the present invention as an infinite number of midway restriction positions are provided. It is. The degree of holding of the opening restriction member is sufficient that the opening restriction member can be held at a certain position against the operating force when the holding member is operated in the opening direction. This is included in the concept of “holding” the opening restricting member in the present invention unless the opening restricting member escapes and its position is not determined when the holding member is operated in the opening direction.

  Furthermore, the first clamping member may be configured as a plate-like member larger than the second clamping member, and the opening limiting member may be attached to the first clamping member. In this case, various shapes can be given to the first clamping member. The 2nd clamping member can be arrange | positioned so that it may hide on the back surface side of the 1st clamping member.

  According to the present invention, in addition to the maximum limit position and the minimum limit position, the opening limit member can be held at a midway limit position between these limit positions. It becomes possible to restrict. Thereby, careless dropping of the sandwiched article or the clip itself can be prevented.

  1 and 2 show one embodiment of a clip to which the present invention is applied. The clip 1 includes a clip body 2 as a first clamping member, and a clamping piece 4 as a second clamping member attached to a back surface 2a of the clip body 2 via a support shaft 3 so as to be swingable. Yes. As shown in detail in FIG. 3, the clip main body 2 has a star-shaped outer shape, and a back surface 2 a has a pair of support walls 10 parallel to each other, and a guide rail 11 disposed substantially in the middle of the support walls 10. And three protrusions 12 extending in a direction orthogonal to the support wall 10 are provided. Further, a strap hole 13 penetrating the clip body 2 is provided next to the protrusion 12. The strap hole 13 is for passing a strap connecting the clip 1 and other articles. Examples of other articles include infant toys.

  As shown in FIG. 4, a support shaft hole 15 for receiving the support shaft 3 is provided at one end portion 10 a of the support wall 10 facing the center side of the clip body 2. An elongated guide hole (guide portion) 16 extending in the longitudinal direction of the support wall 10 is provided between the support shaft hole 15 and the other end portion 10 b of the support wall 10. A plurality of positioning recesses 16 b are formed side by side on the upper wall surface 16 a of the guide hole 16. Of these recesses 16b, the recess 16b closest to the spindle hole 15 has a maximum limit position of a lock 30 (see FIG. 1) described later, and the recess 16b farthest from the spindle hole 15 has a minimum limit position of the lock 30. The midway limit position of the lock 30 is determined by the other recess 16b. In FIG. 4, only one support wall 10 is shown, but the configuration of the opposite support wall 10 is the same. The recess 16b may be provided on the lower wall surface 16c.

  As shown in FIGS. 5 and 6, the holding piece 4 has a holding portion 21 that is opened and closed with respect to the clip body 2 on one end side with a pair of fulcrum portions 20 through which the support shaft 3 is passed. On the side, an operation unit 22 that is operated to open and close the clamping unit 21 is provided. On the back surface 21a of the clamping part 21, there are provided three ridges 23 that mesh with the ridges 12 of the clip body 2 and constitute anti-slip means. On the other hand, on the back surface 22 a of the operation unit 22, a step-like abutting portion 24 whose height gradually decreases from the fulcrum 20 toward the tip of the operation unit 22 is provided.

  The fulcrum part 20 and the operation part 22 of the holding piece 4 are formed to have a width that is somewhat smaller than the interval between the support walls 10 of the clip body 2. The support wall 10 of the clip body 2 and the fulcrum part 20 of the holding piece 4 are penetrated by the support shaft 3 and are connected to each other so as to be rotatable. A torsion coil spring 25 as an urging means is disposed around the support shaft 3 spanned between the support walls 10. One arm 25 a of the torsion coil spring 25 is abutted against the clip body 2 and the other arm 25 b is abutted against the back surface 22 a of the operation portion 22 of the sandwiching piece 4. Is biased around the support shaft 3 so as to be closed.

  Returning to FIG. 1 and FIG. 2, a lock 30 as an opening limiting member is disposed between the clip body 2 and the clamping portion 21 of the clamping piece 4. The lock 30 is formed in a quadrangular prism shape (see FIG. 6), and the guide rail 11 of the clip body 2 is fitted into a guide groove 30a provided on the lower surface of the lock 30, whereby the longitudinal direction of the guide rail 11 (corresponding to the position adjustment direction). ) Along the support wall 10. A lock pin 31 as a support member is passed through the center of the lock 30. Both end portions of the lock pin 31 protrude from the lock 30 and are inserted into the guide holes 16 of the support wall 10. Furthermore, one end of the lock pin 31 passes through the guide hole 16 and protrudes to the outside of the support wall 10, and a cap 32 is attached to the protruding portion. The cap 32 is provided as a portion to which a user attaches a finger when the lock pin 31 is moved along the guide hole 16.

  The width of the guide hole 16 in the vertical direction is the largest at the position serving as the bottom of the recess 16b and the smallest at the position serving as the boundary between the recesses 16b. While moving the lock pin 31 between the recesses 16b, the width of the guide hole 16 is adjusted so that the lock 30 can be held at a position corresponding to each recess 16b until a certain amount of force is applied. For example, the width of the guide hole 16 is set slightly larger than the diameter of the lock pin 31 at the bottom position of the recess 16b, and the width of the guide hole 16 is equal to or more than the diameter of the lock pin 31 at the boundary position between the recesses 16b. The guide hole 16 is formed so that the lock pin 31 cannot get over the boundary between the recesses 16b and stays in the same recess 16b unless the force is set to a small value and a certain amount of force is applied. In order to maintain such a function of the guide hole 16, it is desirable that at least the wear resistance of the inner surface of the guide hole 16 is sufficiently increased. For this purpose, at least the support wall 10 of the clip body 2 may be made of a material having high wear resistance, or the inner surface of the guide hole 16 may be subjected to a surface treatment that increases wear resistance. Of course, wear of the guide hole 16 may be prevented by means other than these.

  In the clip 1 having the above configuration, the lock 30 is disposed between the clip body 2 and the operation portion 22 of the holding piece 4, so that the abutting portion 24 is pressed when the operation portion 22 of the holding piece 4 is pushed down. When the lock 30 comes into contact with the lock 30, no further operation is possible, and the opening amount of the holding piece 4 at the holding portion 21 is limited. Therefore, when the lock pin 31 is positioned in the recess 16b closest to the support shaft 3 and the lock 30 is held at the maximum limit position, the abutment portion 24 of the operation portion 22 remains in contact with the clip body 2. If the relationship between the lock 30 and the abutment portion 24 is set so that the operation portion 22 cannot be pushed down by meshing with the lock 30, the clip 1 can be constrained to a completely closed state as in the conventional clip. . On the other hand, when the lock pin 31 is positioned in the concave portion 16b farthest from the support shaft 3 and the lock 30 is held at the minimum limit position, the operation portion 22 is in contact with the lock 30 on the tip side of the abutment portion 24. If the relationship between the lock 30 and the abutting portion 24 is set, the opening amount of the clip 1 can be secured to a practically sufficient level.

  Then, when the lock pin 31 is positioned in the intermediate recess 16b and the lock 30 is held at any midway limit position, the clamping portion 21 corresponds to the position of the lock 30 as shown in FIGS. The abutting portion 24 comes into contact with the lock 30 in the state of being opened by an amount, and further opening operation of the clamping piece 4 is prevented. Thereby, the clamping piece 4 is restrained in a state in which some article 50 is sandwiched between the clip main body 2 and the clamping portion 21 of the clamping piece 4, and the article 50 or the clip 1 itself is accidentally dropped from the article 50. Can be prevented. As apparent from the comparison between FIG. 7 and FIG. 8, since the stepped abutting portion 24 is provided in the holding piece 4, the abutting is performed in accordance with the change of the concave portion 16 b that holds the lock 30. Surfaces having different heights of the portion 24 come into contact with the lock 30. As a result, the amount of opening of the clip 1 when the position of the lock 30 is shifted by one step as compared with the case where the abutting portion 24 is eliminated or is configured to be a flat and parallel plane with the operating portion 22 is obtained. The adjustment range becomes large. That is, there is an advantage that the opening adjustment amount of the clip 1 with respect to the movement amount of the lock 30 in the position adjustment direction becomes large, and the movement amount of the lock 30 in the position adjustment direction can be set relatively small.

  The present invention is not limited to the above embodiment, and may be implemented in various forms. For example, the lock 30 as the opening limiting member is attached to the clip body 2, but instead of this, the lock 30 is attached to the operation portion 22 side of the holding piece 4 and the structure corresponding to the abutment portion 24 on the clip body 2 side. May be provided. The number of midway restriction positions may be changed as appropriate. By using the frictional force for holding the opening restriction member, the opening restriction member may be held at an infinite number of midway restriction positions, that is, at an arbitrary position between the maximum restriction position and the minimum restriction position. The first clamping member is not necessarily limited to a plate-like member like the clip body 2, and a clamping member equivalent to the clamping piece may be provided as the first clamping member.
