Description

  The present invention relates to a clip provided in an applicator.

There have been many writing tools in which a metal part is attached to a clip portion or a writing material in which a clip itself is formed of a metal material in order to produce a high-quality feeling of the entire product.
Specifically, as disclosed in Japanese Patent Application Laid-Open No. 11-157280, many are known in which a metal clip is press-fitted into a clip mounting hole formed in a resin part.

JP-A-11-157280

  However, the metal clip as in the invention described in Patent Document 1 has difficulty in mass-producing a product having a stable fixing force due to dimensional variation. In particular, when heat treatment is performed during processing, the dimensions are likely to vary, and further, the metal hardness increases due to the heat treatment, making it difficult to deform. There was a possibility that the clip would fall off due to the decrease in press-fitting amount.

Therefore, in view of the above problems, the present invention is a clip provided on the applicator, and the clip is composed of a plurality of mounting parts made of a resin material,
The at least one attachment component is covered with a cover member made of a metal material, and the cover member is positioned between the plurality of attachment components in the axial direction in the longitudinal direction of the applicator, and a part of the cover member or All are sandwiched from one mounting part from the front, and the other mounting part from the rear, and one mounting part from the top, and the other mounting part from the bottom. The gist is that the plurality of mounting parts are locked by these pinching actions.

  The present invention is a clip provided on the applicator, the clip is composed of a plurality of mounting parts made of a resin material, and at least one mounting part is covered with a cover member made of a metal material, The cover member is positioned between the plurality of mounting parts in the axial direction in the longitudinal direction of the applicator, and a part or all of the cover member is attached to one mounting part from the front direction and the other mounting part. The parts are sandwiched from the rear, and one mounting part is sandwiched from above, and the other mounting part is sandwiched from below. By these sandwiching actions, the plurality of mounting parts are locked. As a result, the cover member is sandwiched and positioned, and is fixed by press-fitting the attachment part. That is, since the cover member does not need to be press-fitted directly into the resin part, the clip can be easily assembled and fixed.

An example of the best configuration (Example 1) will be described. In the following description, the front refers to the pen tip side direction, and the rear refers to the side direction in which the clip is attached.
The shaft body 1 includes a front shaft 2, a rear shaft 3, and a sliding case 4. The front shaft 2 is attached to the rear shaft 3 by means such as screwing, and a sliding case 4 is attached to the rear end portion of the rear shaft 3 by means such as press fitting.
At the front end of the front shaft 2, a protruding hole 2 </ b> A is formed in which the writing portion of the refill 5 appears and disappears. Further, the front shaft 2 has a grip 6 made of a rubber-like elastic body inserted therein, but the front shaft 2 is covered with a member made of a rubber-like elastic body by means such as two-color molding or multicolor molding. You may do it. Providing the grip 6 on the outer periphery of the front shaft 2 increases the grip feeling, improves the ease of writing, and further reduces fatigue.
The rear shaft 3 has a cylindrical shape, and no protrusions are provided on the surface. That is, a smooth surface state is formed. This is for improving the decoration of the rear shaft 3, and transfer printing can be performed on the entire circumference. Further, three window holes 3A are formed in the rear shaft 3 in the longitudinal direction. In this example, three window holes 3A are formed, but the total number of refills 5 is three, and the number of window holes 3A formed varies depending on this number.
The window hole 3A is closed at the front and rear ends by a closing portion 3B, and the slider 7 and the base slider 8 are inserted from the rear end of the rear shaft 3, pass through the rear shaft 3, and enter the window hole 3A.
The slider 7 described above is slidably disposed in the window hole 3A of the rear shaft 3. One locking projection 7 </ b> A and a release projection 7 </ b> B are formed on the bottom surface of the slider 7.
The locking projection 7A is inclined in the direction of the central axis of the rear shaft 3 while extending backward, and is inclined in the direction of the central axis of the rear shaft 3 while extending forward from the rear end of the inclined surface 7A1. The inclined surface 7A2 has a shape in which two sides and an angle between them are formed. A vertex formed by two sides of the inclined surface 7A1 and the inclined surface 7A2 is defined as a locking projection vertex 7A3.

When the user advances the slider 7, the slider 7 falls in the axial direction, and the locking projection 7 </ b> A of the slider 7 enters the locking recess 4 </ b> B provided at the center of the beam-shaped partition wall 4 </ b> A in the sliding case 4. Locked. At this moment, the writing portion of the refill 5 protrudes from the protruding hole 2A of the front shaft 2, and writing becomes possible.
The locking recess 4B is formed of a locking recess bottom surface 4B1 and an outer peripheral projection 4B2 protruding forward while surrounding the periphery of the locking recess bottom surface 4B1. In this embodiment, the locking recess 4B has a triangular shape when viewed from the front, and is formed so that the side portion of the triangle comes to the position where the slider is disposed. The outer peripheral projection 4B2 is formed with an inclined surface 4B3 that inclines from the inner side to the outer side of the bottom surface 4B1 of the locking concave portion as it goes forward.
In the state where the locking projection 7A of the slider 7 of Example 1 is locked to the locking recess 4B, the front end of the inclined surface 7A1 of the locking projection 7A and the inclined surface 4B3 of the locking recess 4B (front end of the outer peripheral projection) 4B4) is brought into contact and is locked.
It should be noted that one or both of the locking projection 7A of the slider 7 and the locking recess 4B in the sliding case 4 have a rough surface or a rough surface, or the shape itself is a stepped shape or the like. You may employ | adopt the policy which improves the latching force of 7A and the latching recessed part 4B.
When the writing portion of the refill 5 protrudes, the refill restriction rib 3F provided from the rear shaft inner peripheral surface 3E near the through hole 3D provided in the restriction portion 3C in the rear shaft 3 toward the center of the through hole 3D, and the refill 5 contacts. By this contact operation, the writing portion at the tip of the refill 5 is forced toward the protruding hole 2A at the tip of the front shaft 2. Thereby, the writing part is projected from the projecting hole 2 </ b> A without the refill 5 being bent in the front shaft 2. For example, when the refill 5 is a sharp unit, a built-in sharp lead feeding failure due to bending of the sharp unit itself is prevented, and smooth centering becomes possible.
When the other slider 7 positioned at the rear in the protruding state of the front end of the refill 5 is advanced, the released protrusion 7B of the advanced slider 7 comes into contact with the released protrusion 7C of the slider 7 being locked. The locked slider 7 moves outward in the radial direction, so that the locking projection vertex 7A3 of the locking projection 7A gets over the outer peripheral projection 4B2 of the locking recess 4B, and the locking is released. At the moment, the slider 7 moves backward due to the resilience of the resilience member 9 described later, and the tip of the refill 5 is in a sunk state.
The base slider 8 described later has the same shape as that of the slider 7 in contact with the bottom surface side thereof, that is, the sliding case 4 side. It is.

A refill holding projection 7D protruding in the longitudinal direction is formed at the front end of the slider 7, and the refill holding projection 7D is inserted into the rear end portion of the refill 5 to hold the refill 5 in a press-fit manner. I can do it. The shape of the refill holding projection 7D is not limited to the present embodiment, and a press-fitting relationship may be given by a rib or the like.
The refill 5 can be appropriately selected from a ballpoint pen refill, a sharp unit capable of feeding a sharp lead, and the like. In addition, when a ballpoint pen refill is selected as the refill 5, the resin pipe (ink receiving tube) is colored or colored in a color approximate to the internal ink by transfer printing, etc., and can be identified from the appearance of the user. You can also.
At the front end portion of the slider 7, a flange portion 7 </ b> E with which the rear end portion of the elastic member 9 abuts is formed.
Reference numeral 9 denotes an elastic member 9 such as a coil spring that biases the refill 5 and the slider 7 connected to the refill 5 backward.
As described above, the restricting portion 3C is formed in the intermediate portion of the rear shaft 3, and the restricting portion 3C is formed with three through holes 3D into which the refill 5 is loosely inserted, and the restricting portion 3C. The refill 5 is urged rearward by engaging one end of the elastic member 9 to the rear.

As described above, the sliding case 4 is attached to the rear end portion of the rear shaft 3. In this example, engagement protrusions 4 </ b> C for engaging with the rear shaft 3 are provided at equal intervals on the outer peripheral surface of the sliding case 4. Further, the engagement protrusion 4 </ b> C is engaged with the rear end portion of the window hole 3 </ b> A provided on the outer peripheral surface of the rear shaft 3. In this engaged state, the front half 4D of the sliding case 4 is disposed inside the rear end of the rear shaft 3, while the rear half of the sliding case 4 protrudes from the rear end opening 3G of the rear shaft 3. The protruding rear half of the sliding case 4 is a knock portion 4E, and the entire sliding case 4 slides back and forth with respect to the rear shaft 3 by the knock operation. As a result, when the refill 5 is selected as a sharp unit, the length of the shaft body 1 is suppressed by effectively utilizing the sliding distance of the sharp core feedout in the window hole 3A. The section 4F is formed by the beam-shaped section walls 4A so as to divide the radial direction. The slider 7 attached to the rear end of the refill 5 slides back and forth in the section 4F, and the pen tip of the refill 5 and the tip portion of the sharp unit are immersed. The number of the sections 4F is three in this example, but changes depending on the number of the refills 5.
Moreover, although the sliding case 4 has comprised the bottomed cylinder shape, the cylinder part 4G is lose | eliminated from the intermediate part, and it is in the open state to radial direction. Specifically, a notch 4H is formed, and the notch 4H is in an open state. That is, the notch 4H is used as a sliding surface, and the slider 7 slides in the sliding case 4. The pressing portion 7F of the slider 7 protrudes outward from the window hole 3A of the rear shaft 3, and the pressing portion 7F of the slider 7 slides in the window hole 3A of the rear shaft 3.

An attachment / detachment hole 4I is provided on the rear end surface of the sliding case 4 of the shaft body 1, and a decorative part such as an earphone jack accessory or a functional part such as an eraser, a fluorescent pen, or a correction tool is attached. It is possible.
As described above, two sliders 7 and one base slider 8 are disposed in the three window holes 3A provided in the rear shaft 3. The shape contacting the bottom surface side of the base slider 8, that is, the sliding case 4 side is the same as that of the slider 7, and the operation at the time of locking or releasing is the same as that of the slider 7.
However, on the top surface side of the base slider 8, a clip mounting portion 8 </ b> A that is exposed to the outside through the window hole of the rear shaft 3 is provided. The clip attachment portion 8A has a fitting protrusion 8B for attaching a base clip 10 described later. The fitting protrusion 8B has a U-shape opening toward the rear end side, and has a notch portion 8H having a center portion opened rearward and a rear end portion serving as a stopper portion 8I.
The fitting protrusion 8B has a different role between the front and the rear, and the front front surface portion 8J comes into contact with a fitting protrusion 10E of the base clip 10, which will be described later, to prevent the base clip 10 from coming off backward. On the other hand, the rear side of the fitting protrusion 8B plays a role of not interfering with a narrow portion 10G of the base clip 10 described later by a notch portion 8H provided in the center portion.
Further, the stopper portion 8I at the rear end portion of the fitting protrusion 8B abuts on the stopper contact portion 11F of the clip cover 11 during assembly, thereby providing a function as a forward-preventing retainer. The base slider 8 and a base clip 10 and a clip cover 11 described later function as the clip portion 12 in an assembled state.
Further, the above-described clip attaching portion 8A is provided with a groove portion 8C that opens on the rear end side and the top surface side and extends forward in the axial direction. The cross section of the groove 8C has a T-shaped inverted shape. The T-shaped groove 8C has a fulcrum against a load in the direction of lifting the clip when the T-shaped wide portion 10A provided in the base clip 10 enters the groove 8C when the base clip 10 is attached. Increases and secures strength. Further, an anti-rare rib 8D directed inwardly is provided on the top side of the inner side of the groove portion 8C, and the wide portion 10A of the base clip 10 is restrained from the top direction at the time of assembly. Prevent vertical play.

Reference numeral 10 indicates a base clip. A protrusion 10 </ b> B is provided at the tip of the base clip 10. This corresponds to a protrusion 11A provided on the clip cover 11 side, which will be described later, and is designed so that the protrusion 11A of the clip cover 11 is caught by the protrusion 10B of the base clip 10 when only the clip cover 11 is lifted by the user. Has been.
A ball portion 10 </ b> C is provided on the axial tube side in front of the base clip 10. The ball part 10 </ b> C is designed to contact the rear shaft 3. That is, when paper or the like is sandwiched between the clip portions 12, a gripping force is generated between the ball portion 10C and the rear shaft 3, and a function as a clip can be provided.
In the middle part of the base clip 10, there is a curved bridge-like part 10D connected from the ball part 10C at the front end to the rear end direction, and the rear end side root of the bridge-like part 10D is in the direction of the rear shaft 3. A fitting protrusion 10E that protrudes toward the bottom is provided. The fitting projection 10E fixes the base clip 10 by getting over the fitting projection 8B of the base slider 8 and fitting. Further, the fitting protrusion 8B has an arrowhead shape. That is, it is easy to get over and fit at the time of assembly, but it is difficult to come off after the fit.
There is a clip cover holding portion 10F behind the fitting protrusion 10E. The clip cover holding portion 10F has a shape that gradually increases in diameter toward the rear. This is provided for the purpose of preventing the clip cover 11 from dropping as a light press-fit relationship when temporarily setting the clip cover 11 during assembly. In other words, the clip cover 11 and the clip cover holding portion 10F of the base clip 10 are not in contact with each other at the start of temporary setting, but the two parts are slightly pressed into each other when temporary setting is completed. Can prevent inadvertent dropout. In addition, the assembly method of the clip part 12 is described separately.
An insertion portion 10H including a narrow width portion 10G and a wide width portion 10A is provided below the clip cover holding portion 10F and in the direction toward the rear shaft 3. As described above, the insertion portion 10H is designed with a dimensional relationship so as to enter the groove portion 8C of the base slider 8 during assembly.
Ribs 10I are provided at the rear ends of both side surfaces of the wide portion 10A. This is effective in preventing lateral play by contacting the inner surface of the groove 8C of the base slider 8 during assembly.

Reference numeral 11 indicates a clip cover. The clip cover 11 is made of metal, and the surface thereof is plated to prevent corrosion. In order to ensure strength, heat treatment is also performed. The material can be appropriately selected according to the required function, such as stainless steel or tool steel.
A protrusion 11 </ b> A extends toward the rear end side inside the front end of the clip cover 11. As described above, the protrusion 11A is provided corresponding to the protrusion 10B provided on the distal end side of the base clip 10, and when only the clip cover 11 is lifted, the protrusion 11A of the clip cover 11 becomes the protrusion of the base clip 10. Designed to catch 10B. The inner surface of the tip of the clip cover 11 is deepened by drawing. When the clip cover 11 is assembled with the base clip 10, a gap is provided between the top end surface 10J of the base clip 10 and the end portion inner surface 11B of the clip cover 11. What is present may not be fixed. That is, it is only necessary to provide a non-fixed area.
A concave portion 11C is provided on the top surface of the intermediate portion of the clip cover 11, and a folded portion 11D that is folded inward toward the clip cover 11 is formed on the rear side.
As described above, the front end surface of the folded portion 11D is the stopper contact portion 11F, and a notch portion 11G is provided on the side of the stopper contact portion. A folded portion tip 11E is provided at an intermediate portion of the folded portion 11D, and an eight-shaped inclined surface 11H that opens rearward is formed on the rear side of the folded portion 11D. The inclined surface 11H acts as a guide portion when a base clip 10 and a clip cover 11 described later are temporarily set.
An angle α formed by the folded portion 11D and the side surface portion is an obtuse angle. The reason why α is an obtuse angle is that when the clip portion 12 is assembled, the folded portion 11D of the clip cover 11 slightly contacts the top surface 8F portion of the base slider 8 so as to prevent rattling. Because of that. The angle α formed can be freely selected according to the product and the shape of the clip portion.
In addition, the slope portion 10L of the base clip 10 and the slope portion 11I provided on the clip cover are designed so that the angles are adjusted so that they come into contact with each other when the clip is temporarily set as described later. Thereby, when assembling and fixing to the base slider 8, the slope portion 10 </ b> L provided on the base clip 10 can apply a component force in the axial direction and the radial direction to the clip cover 11. That is, the clip cover 11 can be pressed in the axial direction and the radial direction, and the clip cover 11 can be prevented from rattling.

Next, the assembly method of the clip part 12 is demonstrated. First, the base clip 10 and the clip cover 11 are temporarily set. Specifically, the bridge-like portion 10 </ b> D of the base clip 10 is passed through the gap of the folded portion 11 </ b> D of the clip cover 11. Thereafter, the clip cover 11 is pushed and assembled toward the rear end of the base clip 10 or the base clip 10 is pushed toward the front of the clip cover 11 to complete the temporary setting. At this time, the tip end (turned tip end) 11E of the clip cover 11 folded portion 11D is in a positional relationship in contact with the side surface of the clip cover holding portion 10F of the base clip 10 and is maintained without dropping off, thereby improving the assembly. Has contributed. In the temporarily set state of the base clip 10 and the clip cover 11, it is not a strong press-fit but a light press-fit with a slight wobble, but is an insertion state in which a slight gap is formed. That is, the width of the end of the clip cover 11 folded portion 11D (the folded portion tip) 11E is slightly smaller than the width of the side surface of the clip cover holding portion 10F of the base clip 10, but is the same width or It may be formed slightly larger.
Thereafter, the base clip 10 and the clip cover 11 that have been temporarily set are assembled to the base slider 8 that has been previously attached to the shaft body 1. Specifically, the wide portion 10A of the base clip 10 is inserted into the groove 8C from the rear end side of the base slider 8 toward the front. In this process, the fitting protrusion 10E provided on the base clip 10 is press-fitted over the fitting protrusion 8B provided on the base slider 8, and the clip part is assembled.
In the assembled state, the base clip 10 is fitted with the base slider 8 as described above, and thus does not fall off. Further, the clip cover 11 is also prevented from falling off by a stopper portion 8I provided on the base slider 8 at the front, thereby preventing the clip cover 11 from falling off. Further, the base clip 10 itself acts on the rear side to prevent the dropout. Furthermore, the clip cover 11 is sandwiched between the base slider 8 and the base clip 10. That is, the design is such that the clip cover 11 can be prevented from dropping off at the same time when the base clip 10 is fitted to the base slider 8 and positioned.
Further, the backlash prevention rib 8 </ b> D provided on the base slider 8 in the assembled state is slightly in contact with the upper surface of the wide portion 10 </ b> A of the base clip 10, thereby exerting an effect in preventing the backlash in the vertical direction of the base clip 10. Further, as described above, the rib 10I provided on the base clip 10 in contact with the inner surface of the groove 8C of the base slider 8 in the assembled state prevents lateral play.
When the assembly is completed, a gap is provided between the top surface 10J of the tip of the base clip 10 and the inner surface of the tip of the clip cover 11. Alternatively, it is in contact but not fixed. Further, a gap is similarly provided between the protrusion 10 </ b> B of the base clip 10 and the folded portion 11 </ b> D of the clip cover 11.
Due to this gap, the base clip 10 and the clip cover 11 can move independently on the front end side of the clip portion.

Next, the operation of the present invention will be described.
In this embodiment, the clip cover 11 is fixed by being sandwiched between the base clip 10 and the base slider 8. Specifically, it is prevented from falling off by a stopper portion 8I provided on the base slider 8 at the front and by a base clip 10 itself at the rear. Similarly, in the opening / closing direction of the clip portion, the clip cover 11 is not dropped off because it is sandwiched between the base clip 10 and the base slider 8. That is, it can fix to the clip cover 11 which is a metal member directly without providing a press-fit part, and it contributes to the improvement of assembly property by this.
As described above, since the fitting protrusion 10E provided on the base clip 10 is fitted over the fitting protrusion 8B of the base slider 8, the base slider 8 and the base clip 10 are fixed and the positional relationship is changed. There is no such thing.

The fitting position of the base slider and the base clip is not limited to the method of the first embodiment. For example, as shown in FIGS. 25 to 28 (second embodiment), a fitting protrusion 10K is provided on the side surface of the base clip 10, and the base slider The same effect can be obtained by the design in which the fitting hole 8G is provided on the eight side surfaces.
By providing the fitting portion on the side surface as described above, there is a merit that there is no change in the fitting allowance even when the clip portion 12 is lifted during use, and there is no need to worry about a drop in strength.
As for the assembling method, the base clip 10 and the clip cover 11 are first temporarily set as in the first embodiment. Thereafter, the base clip 10 and the clip cover 11 that have been temporarily set as described above are pushed into the base slider 8 assembled to the shaft cylinder from the rear, and the fitting protrusion 10K provided on the side surface of the base clip 10 is formed on the side surface of the base slider 8. By being caught in the provided fitting hole 8G, it is prevented from coming off and the assembly is completed.
Various other shapes can be adopted, but can be selected as appropriate in consideration of manufacturing costs and functional problems.

Moreover, the form of this invention is not restricted to the composite writing instrument shown in Example 1 and Example 2, but a single refill is accommodated in a shaft cylinder as shown in FIGS. The configuration of the present invention can be applied to various writing instruments.
A specific configuration will be described. The shaft tube 21 has a built-in refill 22 so that a writing portion at the tip of the refill 22 can be exposed to the outside through a projecting hole 23 opened at the tip.
A tail plug 24 is attached to the rear end of the shaft cylinder 21 by screwing. The tail plug 24 has a rotor 25 disposed therein so as to be movable back and forth, and a slider 26 is also disposed behind the rotor 25 so as to be movable back and forth. The vicinity of the end is exposed from the rear end opening of the tail plug 24, and the exposed portion serves as a pressing operation portion 27. The rear end portion of the refill 22 is in contact with the lower end surface of the rotor 25. The refill 22 is urged rearward by a spring 28 to generate a force that always pushes the rotor 25 backward. A protrusion 29 provided on the rotor 25 rotates along a cam groove 30 formed in the tail plug 24. The cam groove 30 has a writing portion immersion position 31 and a writing portion protruding position 32. It is repeatedly provided in a circumferential shape, and each time the pressing operation portion 27 is moved forward, the protrusion 29 of the rotor 25 is alternately locked between the writing portion immersion position 31 and the writing portion protruding position 32.
That is, when the pressing operation portion 27 of the slider 26 is pressed back and forth with a finger or the like, the refill 22 in the shaft cylinder 21 moves back and forth as the rotor 25 moves back and forth. The writing portion at the tip of the refill 22 appears and disappears from the protruding hole 23 of the shaft cylinder 21. At this time, the protrusion 29 of the rotor 25 located at the writing portion immersing position 31 moves so as to be locked to the writing portion protruding position 32 with the rotation, and the state can be maintained.

  The base clip 35 and the clip cover 36 can be attached by providing the clip attachment portion 33 in the tail plug 24 and further providing the clip attachment portion 33 with the clip attachment groove portion 34 having a T-shaped cross section. That is, by inserting the wide width portion 39 of the clip cover 36 into the clip mounting groove 34, the clip mounting portion 33 and the base clip 35 sandwich the top, bottom, left and right. Further, the engaging portion 37 provided on the clip mounting portion 33 and the engaging protrusion 38 of the base clip 35 are fitted to each other so that the tail plug 24 and the base clip 35 are fixed to each other to prevent falling off, and the assembly of the clip portion is completed. To do. In this embodiment, as in the first and second embodiments, when the base clip 35 and the clip cover 36 are temporarily set, the tip (folded portion tip) 41 of the clip cover 36 folding portion 40 is the clip of the base clip 35. It is in a positional relationship in contact with the side surface of the cover holding portion 42 and is configured to be held without dropping off.

39 to 40 show modifications of the shape of the locking projection of the base slider 8 according to the first embodiment. As described above, the shape of the base slider 8 that contacts the bottom surface, that is, the sliding case 4 is the same as that of the slider. Therefore, the configuration of this modification can also be applied to the slider 7.
As in the first embodiment, in this modified example, the inclined surface 7A1 and the inclined surface 7A2 of the locking projection 7A, and portions corresponding to the locking projection vertex 7A3 are formed. In this modified example, the locking projection 8A, the inclined surface 8A1, the inclined surface 8A2, and the locking projection vertex 8A3 are used.
In the first embodiment, as described above, in the state where the locking projection 7A of the slider 7 is locked to the locking recess 4B of the sliding case 4, the inclined surface 7A1 of the locking projection 7A and the locking recess 4B. The front end of the inclined surface 4B3 (outer peripheral projection front end 4B4) is locked by contacting, but it is preferable to get over the outer peripheral projection 4B2 from the state in which the locking projection apex 7A3 is in contact with the locking recess bottom surface 4B1. Since the distance from the locking projection apex 7A3 to the front end of the outer circumferential projection 4B2 (outer circumferential projection front end 4B4) is increased, the locking force of the locking projection 7A is increased.
Further, when the locking projection apex 7A3 is in contact with the locking recess bottom surface 4B1, the inclined surface 7A1 is preferably not in contact with the outer peripheral projection 4B2. When the inclined surface 7A1 comes into contact with the outer peripheral projection 4B2, the movement of the slider 7 is restricted before the locking projection apex 7A3 comes into contact with the locking recess bottom surface 4B1. The distance from the state where the projection vertex 7A3 is in contact with the bottom surface 4B1 of the locking recess to the position over the outer peripheral projection 4B2 is shortened, so that a sufficient locking force cannot be obtained and the locking of the slider 7 is released unintentionally. There is a risk that a malfunction will occur. For this reason, the base slider 8 of this modified example is configured to prevent contact with the outer peripheral protrusion 4B2 in the state where the engaging protrusion 8A is engaged with the engaging recess 4B of the sliding case 4. In comparison, the angle formed by the two sides of the inclined surface 8A1 and the locking recess bottom surface 4B1 is increased. If the angle is increased, the tip portion of the inclined surface 8A1 is formed forward as compared with the first embodiment, and the width of the base portion of the locking projection 8A may be narrowed and the strength may be insufficient. The inclined surface 8A4 is formed to incline backward from the tip of the inclined surface 8A1. Accordingly, the angle formed by the two sides of the inclined surface 8A1 and the bottom surface of the locking recess 4B1 can be increased while securing the thickness of the base of the locking projection 8A.
In this modification, when the base slider 8 is viewed from the side, the angle between the inclined surface 8A1 and the inclined surface 8A2 of the locking projection 8A (locking projection angle 8A5) is 95 degrees. When the locking projection 7A and the locking recess 4B are locked, an angle (X) formed by two sides of the inclined surface 8A1 and the locking recess bottom surface 4B1 is 32 degrees (the inclined surface 8A1 and the axis The angle formed by the two sides of the center line of the main body 1 (the dashed line in FIG. 40) is 122 degrees. Further, when the locking projection 8A and the locking recess 4B are locked, if the angle (X) formed by the two sides of the inclined surface 8A1 and the locking recess bottom surface 4B1 is smaller than 15 degrees, Since the inclined surface 8A1 of the stop protrusion 8A is likely to come into contact with the outer peripheral protrusion 4B2 before coming into contact with the engaging recess bottom face 4B1, the front end of the outer peripheral protrusion 4B2 from the engaging protrusion apex 8A3 (the front end of the outer protrusion) 4B4) is shortened and the locking force is reduced. When X is larger than 60 degrees, the catch is too strong, and there is a problem that it is difficult to release. Therefore, the angle X is preferably 15 degrees or more and less than 60 degrees.
Further, it is a perpendicular line passing through the outer peripheral projection front end 4B4 and the locking recess bottom surface 4B1, and the distance (Y) from the outer projection front end 4B4 to the locking recess bottom surface 4B1 is 0.26 mm.
Further, if the locking projection apex 8A3 is made to have a radiused chamfer radius or an edge shape, the locking projection apex 8A3 is easily caught by the locking recess 4B when the locking is released, and the locking force is increased.
Note that, as in the present invention, in particular, a slider that adds a clip function has a ball portion that abuts the shaft during locking, and the reaction force of the clip acts in the unlocking direction. Cheap. For this reason, it is better to increase the locking force than sliders other than the slider to which the clip function is added.
