Description

  The present invention relates to a clip attached to a member to be attached such as a writing instrument.

As for the clip for writing instruments, for example, as described in Patent Document 1, the base end portion of the elastically deformable pressure contact piece (clip body) is spaced apart from the outer peripheral surface of the writing instrument body in parallel with the base end portion. Mounting, elastically clamped objects such as clothes pockets, notebooks, notebooks, etc., inserted between the protrusions (balls) protruding from the inner surface of the free end of the pressure contact piece and the outer peripheral surface of the writing instrument body The one that can be pinched is generally used. Such a clip has the following problems.
(B) Since the pressure contact piece is attached to the outer peripheral surface of the writing instrument body so as to protrude greatly, not only the appearance is bad, but also the storage efficiency is poor when storing many writing instruments in a box etc. Become.
(B) Since the protrusions are pressed against the object to be held such as pockets of clothes almost at points, and the holding pressure area and frictional resistance of the object to be held are small, the writing instrument may fall off the object to be held. In particular, when the clip is made of a synthetic resin, the elastic holding force of the pressure contact piece gradually becomes weak due to aging deterioration or the like, so that the sufficient function as the clip may not be achieved.
(C) Since the amount of elastic deformation of the pressure contact piece and the clamping pressure by the protrusion are limited, it is not suitable for clamping an object to be clamped with a large thickness.

  Patent Document 3 describes a clip that can solve the problems (A) and (B), and Patent Document 2 describes a clip that can solve the problem (C). These clips also have the following problems.

JP 2003-246189 A Japanese Utility Model Publication No. 57-68387 JP 2007-253329 A

  The clip described in Patent Document 2 bends a plate material such as spring steel into a hairpin shape, inserts and fixes one fixing piece into the cylindrical shaft, and holds the object to be clamped. The pressure contact piece is brought into contact with the outer peripheral surface of the cylindrical shaft, and the object to be clamped is elastically sandwiched between the other pressure contact piece and the outer peripheral surface of the cylindrical shaft. In addition to not projecting greatly outward from the outer peripheral surface of the cylindrical shaft, there is an advantage that the clamping area and frictional resistance of the object to be clamped can be increased.

  However, since almost all of the length direction of one fixed piece is fixed in close contact with the inner surface of the cylindrical shaft, when the object to be clamped is clamped, the other press-contacting piece opens the bent portion in the expanding direction. While being elastically deformed, it is elastically deformed outward so as to stand obliquely with the vicinity of the top of the bent portion as a fulcrum. Therefore, the clamping force of the object to be clamped by the pressure contact piece increases as it approaches the bent part of the clip and decreases as the free end part, and there is a problem that the object to be clamped cannot be clamped with a uniform clamping force. This phenomenon is more likely to occur as the thickness of the object to be clamped increases.In particular, when the object to be clamped with a large thickness is sandwiched, the pressure contact piece is located near the top of the bent part with respect to the outer peripheral surface of the writing instrument body and the fixed piece. As a fulcrum, it is elastically deformed obliquely upward into a V shape, and there is a risk that a gap will be formed between the free end of the pressure contact piece and the object to be clamped.

  In addition, the clip described in Patent Document 3 has a convex portion projecting on the outer peripheral surface of the writing instrument main body, and an intermediate portion in the longitudinal direction of the clip main body can be swung with a shaft and relatively moved outward. The object to be sandwiched between the writing instrument body and the clip body is clamped by the biasing force of the leaf spring provided between the writing instrument body and the clip body. When the clip is clamped, the clip main body moves outward relative to the writing instrument main body, so that even a thick object to be clamped can be clamped without any trouble.

However, since a convex portion is provided on the outer peripheral surface of the writing instrument body, and the clip main body is attached to the convex portion so as to be relatively movable outward, the protruding dimension of the clip from the outer peripheral surface of the writing instrument body However, there is a problem that it becomes larger than the clip described in Patent Document 1.
Further, since the number of clip parts and assembly man-hours are large, there is a problem that the cost of the writing instrument becomes high.

  The present invention has been made in view of the above problems, and can reduce the projecting dimension of the press-contacting piece that presses the object to be clamped as much as possible, and can be attached to the mounted member. In addition, it is possible to increase the clamping force of the object to be clamped by stably clamping with a large clamping area, and furthermore, as a simple structure, it can be easily attached to the mounted member, so that the cost can be reduced. The purpose is to provide a clip.

According to the present invention, the above-mentioned problems are solved as follows.
(1) A clip attached to a member to be attached so that the object to be clamped can be clamped, wherein the free end is pressed against the inner surface of the attached member, and the portion from the free end to the base end is An elastically deformable fixing piece that is attached to the inner surface of the attached member so as to be spaced inward from the inner surface of the attached member, and an edge portion of the attached member is covered by a base end portion of the fixed piece. A top piece extending outwardly, and an elastically deformable pressure contact piece continuously provided to face the fixed piece at the free end of the top piece, and an outer periphery of the upper plate of the attached member The fixed portion is provided with an opening that is open upward so that the fixed piece can be inserted into the attachment member from above and the top piece is movable inward and outward. The attached portion is engaged with the engaged portion provided on the inner surface of the attached member. Engaging portion for retaining fit is provided the fixing piece inserted therein to the mounting member, at the time of non-use, at least part of the length of the pressing member is, it almost to the outer surface of the mounted member It is made to press in parallel, sandwiching the object to be clamped between the pressure contact piece and the mounting member, until the tip of the clamped object reaches the position of the free end of the fixed piece, When the pressure contact piece is elastically deformed outward and the tip of the object to be clamped is inserted to a position beyond the free end of the fixed piece, the pressure contact piece is substantially parallel to the outer surface of the object to be clamped. The top piece moves outward by the thickness of the object to be clamped, and the fixed piece can tilt outward with its free end as a fulcrum.

With such a configuration, when not in use, at least a part of the pressure contact piece in the longitudinal direction is in pressure contact with the outer surface of the mounted member in parallel with it, and the outward projecting dimension of the pressure contact piece is reduced. The design is well organized and the mounted member can be made compact.
Also, until the tip of the object to be clamped reaches the fulcrum of the free end of the fixed piece, only the pressure contact piece is elastically deformed outward with the top piece as a fulcrum, so the object to be clamped can be easily inserted with a light force. Can do. When the tip of the object to be clamped is inserted to a position beyond the position of the fulcrum of the fixed piece, the fixed piece tilts outward, the pressure contact piece becomes almost parallel to the object to be clamped, and the fixed piece and the pressure contact piece are expanded. Since the pressure contact piece is strongly pressed against the outer surface of the object to be clamped, the clamping force of the object to be clamped is increased.
Furthermore, since the pressing piece is uniformly pressed against the outer surface of the object to be clamped, and the pressing area and frictional resistance of the object to be clamped are large, the clamping force of the object to be clamped can be increased and stably clamped. And the object to be clamped is prevented from falling off.
Furthermore, the fixed piece is inserted into the inside from above the opening provided in the upper plate of the mounted member, and the engaged portion of the free end portion of the fixed piece is simply engaged with the engaged portion of the mounted member. Thus, since the clip can be easily attached to the member to be attached by removing the clip, the number of parts and the number of assembling steps can be reduced, and the cost can be reduced.

(2) In the above item (1), the length of the fixed piece is shorter than the pressure contact piece.

  With such a configuration, the resistance force when the fixing piece is elastically deformed in the expanding direction is increased, and the elastic reaction force is also increased, so that the clamping force of the object to be clamped is increased.

(3) In the above item (2), the length of the fixed piece is set to 1/4 to 1/2 of the length of the pressure contact piece.

  With such a configuration, when the fixed piece is elastically deformed in the expanding direction, a preferable resistance force and elastic reaction force can be obtained, and the object to be held can be securely held with a required holding force.

(4) above (1) to (3) Oite to any one of Items, while the recess or projection of the engaged portion, the engagement of the outwardly the engaging portion is engaged with the recess or projection A piece.

  With such a configuration, simply by inserting the fixed piece along the inner surface of the attached member, the engaging piece of the fixed piece automatically engages with the recess or the protrusion on the inner surface of the attached member. It becomes easier to attach the clip to the member to be attached.

( 5 ) In any of the above items (1) to ( 4 ), either the outer surface of the free end portion of the fixed piece slightly closer to the top piece or the inner surface of the attached member facing this portion When the fixed piece is tilted outward by a certain amount or more during clamping of the clamped object, it comes into contact with either one of the opposing surfaces of the mounted member and the fixed piece, thereby becoming a secondary fulcrum of the fixed piece. Protrusions are provided.

  With such a configuration, when the object to be clamped with a large thickness is sandwiched and the fixed piece tilts outward by a certain amount or more, the projecting portion that is a secondary fulcrum contacts the inner surface of the mounted member, and the projecting portion Since the fixed piece tilts outward with fulcrum as the fulcrum, the effective length of the fixed piece is substantially shortened. As a result, since the resistance force and the elastic reaction force when the fixed piece elastically deforms in the expanding direction become large, even a thick object to be clamped can be stably clamped with a large clamping force.

( 6 ) In any one of the above items (1) to ( 5 ), the fixed piece, the top piece, and the pressure contact piece are integrally formed by bending an elastic thin thin plate material.

  With such a configuration, the clip can be easily and inexpensively manufactured by pressing or the like, and since it is formed of a thin plate material, the outward projecting dimension of the pressure contact piece is extremely small.

( 7 ) In any one of the above items (1) to ( 6 ), the attachment member is a writing instrument having a cylindrical shaft, and the fixed piece is cylindrical through an opening provided in the upper surface plate of the cylindrical shaft. It is inserted into the shaft, and the free end portion of the fixed piece is pressed against the inner surface of the cylindrical shaft to prevent it from being removed, and the pressure contacting piece is pressed against the outer peripheral surface of the cylindrical shaft.

With such a configuration, the clip can be easily attached to the cylindrical shaft simply by providing an opening on the upper surface plate of the cylindrical shaft of the writing instrument, and the protruding dimension of the pressure contact piece from the outer peripheral surface of the cylindrical shaft The writing instrument can be made compact.

  According to the present invention, the projecting dimension of the pressure contact piece that presses the object to be clamped can be made as small as possible so that it can be attached to the mounting member, and the object to be clamped can be stabilized with a uniform clamping pressure and a large pressing area. A clip that can increase the clamping force of the object to be clamped by being clamped well can be provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a side view showing an example in which a clip 1 according to the first embodiment of the present invention is attached to a cylindrical shaft of a writing instrument 2 such as a ballpoint pen as an attached member, that is, a cap 3. In the following description, the inner peripheral surface side of the cap 3 will be described as the inner side, and the outer peripheral surface side will be described as the outer side.

  As shown in FIG. 2 to FIG. 6, the clip 1 is formed by integrally bending an elongated thin plate material made of, for example, stainless steel having elasticity, and is fixed in the vertical direction that can be elastically deformed in the plate thickness direction. A piece 4, a short top piece 5 having a flat top surface, and a free end of the top piece 5, which are connected to the upper end, which is the base end thereof, are inclined slightly upward and obliquely outward. 4 and press-contacting pieces 6 that are arranged vertically downward so as to face each other and elastically deformable in the plate thickness direction. The top piece 5 is inclined obliquely upward because the top surface of the cap 3 is also inclined obliquely upward. Thus, when the top piece 5 is inclined obliquely upward, the top surface and the cap 3 are inclined. Can be aligned with the same surface. The top piece 5 may be curved horizontally or arcuately, or the entire clip 1 can be integrally formed of a hard synthetic resin or the like.

  An outward arcuate bent portion 6 a for facilitating insertion of the object to be clamped is formed at the free end portion of the pressure contact piece 6. The vertical dimension of the pressure contact piece 6 is substantially the same as the length of the cap 3 in this example, for example, about 50 mm, and the vertical dimension of the fixed piece 4 is shorter than that of the pressure contact piece 6. Is approximately 1/3 of the length. When the length of the fixed piece 4 is increased, the fixed piece 4 is easily elastically deformed with the engaging piece 7 as a fulcrum, and the clamping force by the pressure contact piece 6 is reduced. In order to obtain a required clamping force, The length of the fixed piece 4 is preferably in the range of about 1/4 to 1/2 of the length of the pressure contact piece 6.

  As shown in FIGS. 2 and 4, the width of the top piece 5 and the pressure contact piece 6 is equal, and the width dimension from the free end of the fixed piece 4 to the slightly lower part of the top piece 5 is the same as that of the top piece 5 and the pressure contact piece 6. It is slightly smaller than the width dimension. However, the entire width of the clip 1 including the fixed piece 4, the top piece 5, and the pressure contact piece 6 may be made equal.

  The fixed piece 4 is gently curved so that the central portion bulges outward in a side view, and the distance between the fixed piece 4 and the pressure contact piece 6 gradually decreases from the base end portion toward the free end portion. It is bent slightly outward. As will be described in detail later, an engagement piece 7 that is U-shaped upward as viewed from the side and that is a fulcrum of the fixing piece 4 is externally attached to the free end portion of the fixing piece 4. It is connected in the direction. A gap S substantially equal to the thickness of the peripheral wall of the cap 3 is formed between the outer surface of the engagement piece 7 and the facing surface of the pressure contact piece 6. The gap S may be smaller than the wall thickness of the peripheral wall of the cap 3.

Next, a procedure for attaching the clip 1 having the above configuration to the cap 3 will be described.
As shown in FIG. 5 and FIG. 6, an opening 8 having a square shape in plan view that opens upward and communicates with the inside of the cap 3 is formed on the outer peripheral portion of the top plate 3 a that is inclined slightly upward. Is formed. On the opening 8 side, a triangular projection 9 having an upper surface inclined obliquely downward is provided on the inner surface of the upper peripheral wall of the cap 3 so as to project in the axial direction of the cap 3. In addition, the dimension from the upper surface of the cap 3 to the lower end of the protrusion 9 and the dimension from the upper surface of the top piece 5 of the clip 1 to the upper end of the engagement piece 7 of the fixing piece 4 are substantially equal.

In use, as shown in FIG. 5, the edge of the upper end of the peripheral wall in the cap 3 is covered with the top piece 5, and the peripheral wall is sandwiched between the engaging piece 7 and the pressure contact piece 6 of the fixed piece 4, The fixing piece 4 is inserted into the cap 3 through the opening 8. Then, the lower end of the engagement piece 7 comes into contact with the inclined surface of the upper surface of the protrusion 9, so that the fixed piece 4 is slightly elastically deformed inward, and when the engagement piece 7 gets over the protrusion 9, the protrusion The upper end of the engagement piece 7 is automatically elastically engaged with the lower end of the portion 7. As a result, the free end portion of the fixed piece 4 is secured to the inner surface of the cap 3 and is fixed, and when not in use, the portion excluding the bent portion 6a of the free end portion of the pressure contact piece 6 is It comes into pressure contact with the outer peripheral surface in parallel with it.
After the clip 1 is attached, the fixed piece 4 can tilt outwardly with the engaging piece 7 as a fulcrum between the upper end of the peripheral wall of the cap 3 and the lower surface of the top piece 5, and the clip 1 is vertically A slight gap is provided so as not to rattle in the direction.

  Next, with reference to FIGS. 7-12, the effect | action of the clip 1 and the aspect of clamping of a to-be-clamped thing are demonstrated. In this embodiment, since the member to be attached is the cap 3 of the writing instrument 2, examples of the object 10 to be clamped of the clip 1 include a cloth such as a pocket of clothes, a notebook, a notebook, or a spine thereof.

  As shown in FIGS. 7 and 8, when the object to be clamped 10 is inserted through the gap between the bent portion 6 a formed at the free end of the pressure contact piece 6 and the outer peripheral surface of the cap 3, the object to be clamped Until the tip of 10 reaches the engagement piece 7 which is the fulcrum of the fixed piece 4, only the pressure contact piece 6 is gradually elastically deformed outward using the outer end of the top piece 5 as a fulcrum.

When the object to be clamped 10 is further inserted and the tip of the object 10 exceeds the position of the engagement piece 7 that is the fulcrum of the fixed piece 4, the fixed piece 4 supports the engagement piece 7 as shown by the arrows in FIG. As a result, the top piece 5 moves outward by the thickness of the object to be clamped 10. As a result, the pressure contact piece 6 tilts inward, is in parallel with the cap 3 and the object to be clamped 10 and uniformly abuts on the outer surface thereof.
At this time, the fixed piece 4 and the pressure contact piece 6 are elastically deformed in the expanding direction by the thickness of the object to be clamped 10, so that the pressure contact piece 6 is held by the elastic reaction force of the object to be clamped 10. The object 10 is pressed against the outer surface, and the object to be clamped 10 is strongly held between the pressing piece 6 and the outer peripheral surface of the cap 3.

  The clamping force at this time becomes smaller as the length of the fixed piece 4 becomes longer than the pressure contact piece 6. This is because, as the length of the fixed piece 4 becomes longer, the fulcrum of the free end portion is separated from the top piece 5 and when the object to be clamped 10 is inserted, it becomes easier to be elastic in the expanding direction by the lever principle. It is. Therefore, it is not preferable to make the length of the fixed piece 4 too long. As described above, in order to obtain a required clamping force, the length is set to about 1/4 to 1/1 of the length of the press contact piece 6. A range of 2 is preferable.

  As shown in FIG. 10, after the tip of the object to be clamped 10 exceeds the position of the engagement piece 7, even if the object to be clamped 10 is further inserted, the fixing piece 4 hardly tilts and the pressure contact piece Only the clamping area of the object 10 to be clamped by 6 becomes large.

  FIG. 11 shows an example in which the object to be clamped 10 having a large thickness is clamped. At this time, the amount of tilting of the fixed piece 4 increases by the amount of the thickness of the object to be clamped 10 increased. Therefore, in the same manner as described above, the pressure contact piece 6 is in parallel with the outer surface of the object to be clamped 10 and presses against it. In addition, the fixed piece 4 and the pressure contact piece 6 are greatly elastically deformed in the expanding direction by an amount corresponding to the increase in the thickness of the object 10 to be sandwiched, and their elastic reaction force is increased. The clamping force is also increased.

  As described above, in the clip 1 of the first embodiment, when not in use, the pressure contact piece 6 is in pressure contact with the outer peripheral surface of the cap 3, and the outward projecting dimension is extremely small. Therefore, the writing tool 2 is compact.

  Further, until the tip of the object to be clamped 10 reaches the position of the engagement piece 7 which is the fulcrum of the free end portion of the fixed piece 4, only the pressure contact piece 6 is elastically deformed outward with the top piece 5 as a fulcrum. The sandwiched object 10 can be easily inserted with a light force. When the tip of the object to be clamped 10 is inserted to a position beyond the fulcrum of the fixed piece 4, the fixed piece 4 tilts outward, the pressure contact piece 6 becomes parallel to the object to be clamped 10, and the fixed piece 4 and the pressure contact piece 6 Is elastically deformed in the expanding direction, and the pressure contact piece 6 is strongly pressed against the outer surface of the object 10 to be clamped, so that the clamping force of the object 10 to be clamped is increased.

  Furthermore, since the pressure contact piece 6 is uniformly pressed against the outer surface of the object to be clamped 10 and the clamping area and frictional resistance of the object to be clamped 10 are large, the clamping force of the object to be clamped 10 is increased and this is stably performed. Therefore, the object 10 or the cap 3 is prevented from falling off.

  The clip 1 has a single structure, and the fixed piece 4 is inserted into the inside of the opening 8 of the cap 3, and the engaging piece 7 of the free end is elastically engaged with the protrusion 9 on the inner surface of the cap 3. Therefore, the number of parts and the number of assembling steps can be reduced, and the cost can be reduced.

  FIG. 12 shows a main part of the cap 3 including the clip 1 according to the second embodiment. In this example, a concave portion 11 as an engaged portion is provided on the inner surface of the cap 3 and the fixing piece 4 is provided. An outwardly extending engagement piece 12 as an engagement portion is projected from the free end of this, and the engagement piece 12 is elastically engaged with the recess 11, and the fixed piece 4 tilts with the engagement piece 12 as a fulcrum. It is like that. Also in this embodiment, the same operational effects as described above can be obtained.

  FIG. 13 shows the main part of the cap 3 including the clip 1 according to the third embodiment. In this example, the thickness of the base end portions of the top piece 5 and the fixed piece 4 and the pressure contact piece 6 is increased. It is a thing. In this way, when the object to be clamped 10 is inserted, the resistance force when the fixed piece 4 and the pressure contact piece 6 are elastically deformed in the expanding direction increases, and the elastic reaction force thereof also increases. 10 pinching force increases. Note that the clip 1 of this embodiment can be formed of a hard synthetic resin or the like.

  FIG. 14 shows a main part of the cap 3 including the clip 1 according to the fourth embodiment. In this example, the outer surface of the free end portion of the fixed piece 4 slightly closer to the top piece 5 than the engaging piece 7 is shown. Further, a protruding portion 13 having a slightly smaller protruding dimension than the engaging piece 7 is provided so as to serve as a secondary fulcrum of the fixing piece 4.

  When the protrusion 13 serving as such a secondary fulcrum is provided on the fixed piece 4, when the object 10 having a small thickness is clamped, the fixed piece 4 tilts with the engaging piece 7 as a fulcrum. As shown in FIG. 15, when the object 10 having a large thickness is sandwiched and the fixed piece 4 is tilted outward by a certain amount or more, the protrusion 13 as a secondary fulcrum is brought into contact with the inner surface of the cap 3. The fixed piece 4 tilts outward with the protrusion 13 as a fulcrum. If it becomes like this, since the effective length of the fixed piece 4 will become short substantially, the resistance force and elastic reaction force at the time of elastically deforming in an expansion direction will become large. As a result, even the object to be clamped 10 having a large thickness can be stably clamped with a large clamping force. The clip 1 of this embodiment can also be molded from a hard synthetic resin or the like. Further, the protrusion 13 may be fixed to the fixing piece 4 made of a thin plate material as in the first embodiment by welding, bonding or the like. In this embodiment, the protrusion 13 may be provided on the inner surface on the cap 3 side, contrary to the above.

The present invention is not limited to the above embodiment.
In the said embodiment, although the clip 1 was made into thin plate shape, it is good also as a rod-shaped thing.

  Moreover, in the said embodiment, although the opening part 8 is provided in the upper surface of the cap 3, and the fixed piece 4 is inserted from this opening part 8, an opening part is provided in the surrounding wall part of the cap 3, and this The fixing piece 4 may be inserted from the opening.

  Furthermore, in the said embodiment, although the bending part 6a is provided in the free end part of the press-contacting piece 6, such a bending part 6a is abbreviate | omitted and it is set as the straight-shaped press-contacting piece 6, or the press-contacting piece 6 A ball portion having a small projecting dimension may be provided on the surface of the free end portion facing the attached member.

  In the above embodiment, the entire pressure contact piece 6 except for the bent portion 6a is in pressure contact with the outer surface of the cap 3 in parallel with the outer surface of the cap 3 when not in use. And the intermediate part or the like is bent slightly outward so as to be separated from the outer surface of the cap 3, and the entire pressure contact piece 6 excluding the bent part is parallel to the outer surface of the cap 3 when not in use. You may make it press-contact.

  In the said embodiment, although the example which attached the clip 1 of this invention to the cap 3 of the writing instrument 2 was attached, for example, it attaches to the cylindrical shaft body of a writing instrument without a cap, such as a knock-type ball-point pen and a mechanical pencil, It can be attached to a member other than a writing instrument, such as a clipboard, a bookmark, a penlight, a pointing stick, or a clip such as a pedometer or various accessories. The cap 3 to which the clip 1 can be attached may be a cylindrical shaft having a non-circular shape such as an ellipse or a polygon other than the cylindrical shaft as described above.
