  An embodiment of the present invention will be described with reference to the drawings. The clip 1 shown in FIGS. 1 to 3 is long and wide in the left-right direction. The clip 1 is provided with two clamping portions P for clamping a sheet-like object to be clamped such as paper. In the following description, the clip 1 side of the clip 1 is the front, the opposite side of the clip P is the back, the left when viewing from the rear is the left, and the right is the right. Further, description will be made with the upper side of the clip 1 in FIG. 1 as the upper side and the lower side as the lower side.

  The clip 1 has a base 2 provided on the lower side of the clip 1 and a main plate 3 provided on the upper side of the clip 1. The base plate 2 and the main plate 3 are both substantially plate-shaped and long in the left-right direction. Specifically, as shown in FIG. 4, the base 2 includes a substantially flat front half 2a and a rear half 2b. The rear half 2b is formed so as to protrude rearward from the central portion of the front half 2a in a plan view trapezoidal shape. On the front side of the front half 2a of the base 2, an inclined part 2a1 that is inclined downward from the upper surface of the base 2 is formed. The inclined portion 2a1 is formed over the longitudinal direction of the front half 2a of the base 2. Since the inclined part 2a1 is formed in a convex curved shape when viewed from the side (see also FIG. 6), it has a high design. The base-side clamping part P1 on the base 2 side is provided in the inclined part 2a1.

  A clamping member 4a is provided in each base side clamping part P1 in the vicinity of the left and right ends of the inclined part 2a1. The clamping member 4a provided on the base 2 is formed long in the longitudinal direction of the clip 1 and has a flat upper surface. The clamping member 4a is formed of an elastomer that is a soft elastic material. The clamping member 4a is formed by two-color molding together with the base 2 formed by injection molding with a resin material, and is firmly fixed to the base 2. On the other hand, a holding pin hole 2 c into which a holding pin 7 described later is inserted is formed at the center of the base 2. Long rectangular holes 2d are formed in the left and right sides of the holding pin hole 2c.

  As shown in FIG. 3, a magnet 6 serving as an attracting member is provided on the lower surface of the base 2. The magnet 6 is formed in a rectangular shape in plan view that is long in the longitudinal direction of the clip 1. As shown mainly in FIG. 4, the magnet 6 is housed in a metal holding plate 5. The holding plate 5 includes a plate body 5a. The plate body 5 a is formed as a long rectangular shape in plan view that is long in the longitudinal direction of the clip 1. The plate body 5a is formed in a U shape with the opening facing downward in a side view. Therefore, the plate body 5a is opened on the left and right sides, and wall portions 5a2 extending downward are formed on the front and back of the upper surface plate 5a1, respectively. The magnet 6 is accommodated in the opening of the plate body 5a between the front and rear wall portions 5a2. The holding plate 5 (plate body 5a) is a yoke, and increases the attractive force when the magnet 6 is attracted to a display surface such as a metal whiteboard. From both left and right edges of the upper surface plate 5a1 of the plate body 5a, shaft support portions 5b are erected upward. A shaft hole 5b1 into which a shaft 9 described later is inserted is formed in the shaft support portion 5b. The shaft support portion 5 b is inserted through the rectangular hole 2 d of the base 2. A hole 5a3 is provided at a position slightly above the center of the upper surface plate 5a1 of the holding plate 5.

  As shown in FIG. 3, buffer members 8 are respectively provided on the left and right sides of the magnet 6. A plurality of grooves 8a are formed on the lower surface of the buffer member 8 in the front-rear direction. The lower surface of the buffer member 8 slightly protrudes from the lower surface of the magnet 6 in the assembled state of FIG. The buffer members 8 are each formed of an elastic material such as a rubber material. Accordingly, when the magnet 6 is attracted to the posting surface, the buffer member 8 comes into contact with the posting surface before the magnet 6 and bends due to the attracting force of the magnet 6. Damage is reduced.

  As shown in FIG. 4, the magnet 6 is provided with a hole 6 a through which the holding pin 7 is inserted. Therefore, the magnet 6 is fixed to the base plate 2 together with the holding plate 5 with the holding pin 7 inserted through the hole 6 a of the magnet 6, the hole 5 a 3 of the holding plate 5 and the holding pin hole 2 c of the base plate 2. The holding pin 7 has an upper flange 7a connected to the cylindrical shaft 7b by caulking or the like. Thereby, the base | substrate 2, the holding plate 5, and the magnet 6 are hold | maintained between the upper collar | casing 7a and the lower collar 7c.

  On the other hand, as shown in FIG. 4, the main plate 3 is formed with an overhang portion 3 a in which the front left and right end portions project in a substantially rectangular shape in plan view. A recess 3b is formed between the left and right projecting portions 3a. On the rear side of the central portion of the main plate 3, a grip portion 3c is formed that protrudes in a substantially trapezoidal shape in plan view with a lateral width equivalent to the width of the concave portion 3b as a base end side. The rear edge portion of the grip portion 3c is a finger hook portion 3c1 that curves and rises upward (see also FIG. 6). Since the finger can be easily hooked by the finger hooking portion 3c1, the clip 1 can be easily opened and closed by gripping the latter half 2b and the gripping portion 3c of the base 2 with fingers, and the gripping portion can be used even when the clip 1 is posted. The clip 1 can be easily opened and closed simply by pressing the 3c (finger holding portion 3c1).

  As shown in FIG. 5, a main plate side clamping portion P <b> 2 on the main plate 3 side is provided on the lower surface of each overhang portion 3 a of the main plate 3. Each main plate side clamping portion P2 includes a clamping member 4b. The clamping member 4b is formed long in the longitudinal direction of the clip 1 and protrudes in a semicircular shape in a side view (see also FIG. 6). Each clamping member 4b is formed of an elastomer which is a soft elastic material. The two clamping members 4b are formed by two-color injection molding together with the main plate 3 formed of a resin material, and are firmly fixed to the main plate 3. And each clamping member 4b by the side of the main board 3 is each formed substantially the same length in the left-right direction with the clamping member 4a by the side of the base | substrate 2 respectively.

  On the surface side of each of the left and right overhang portions 3a, there are provided convex portions 3a1 that are formed to protrude slightly in the left-right direction. Each convex portion 3a1 has a longitudinal direction substantially the same as the sandwiching members 4a and 4b, and has an end portion that is a convex arc shape in plan view. Each convex part 3a1 is a mark indicating that the position of the clamping members 4a and 4b is the clamping part P.

  As shown in FIG. 5, shaft support portions 3d are formed on the lower surface of the main plate 3 so as to protrude downward at two locations. Each shaft support portion 3d has a shaft 9 inserted through the shaft hole. In the assembled state, the two shaft support portions 3 d of the main plate 3 are positioned between the shaft support portions 5 b of the holding plate 5. The shaft 9 is inserted through the shaft hole 5 b 1 of each shaft support portion 5 b of the holding plate 5 and the shaft hole of each shaft support portion 3 d of the main plate 3. In this way, the main plate 3 is provided so as to be rotatable with respect to the base 2. And the torsion coil spring 10 is wound around the outer periphery of the shaft 9.

  As shown in FIG. 2, the torsion coil spring 10 includes two arms 10a and 10b. One arm 10 a is in contact with the upper surface of the rear half 2 b of the base 2. The other arm 10 b is in contact with the lower surface of the grip portion 3 c of the main plate 3. In this way, the main plate 3 is biased in the direction in which the front side closes with respect to the base 2. Therefore, as shown in FIG. 5, each base side clamping part P1 provided with the clamping member 4a and formed in the inclined part 2a1 is formed so as to be able to contact each main plate side clamping part P2 provided with the clamping member 4a. And each clamping part P is comprised by the base | substrate side clamping part P1 and the main board side clamping part P2.

  6 and 7 show a state in which the paper S is sandwiched by the clip 1 and the clip 1 is attached to the display surface 30 such as a white board. When the sheet S, which is a sheet-like object, is sandwiched between the two sandwiching portions P, the sheet S in the sandwiching portion P, that is, the upper portion of the paper S sandwiched between the sandwiching members 4a and 4b is inclined in the inclined portion 2a1. It is clamped while following the above. Then, at the position where the upper portion of the paper S that is sandwiched and the posting surface 30 intersects, the paper S is formed with a bent portion S1 that is convexly curved toward the back side of the paper S in a side view. Then, the back surface of the paper S below the bent portion S <b> 1 is brought into contact with the posting surface 30.

  At this time, the rigidity of the upper part of the paper S is increased by the action of the bending portion S1. Therefore, the fluttering at both ends at the top of the paper S is reduced. And since the back surface of the paper S below the bending part S1 is in contact with the posting surface 30, the fluttering of the paper S is also reduced below the paper S.

As shown in FIG. 6, in the clip 1, the relationship between the holding force F and the weight G of the paper S when the clamping members 4 a and 4 b clamp the paper S in the clamping part P is expressed by the following equation.
F = μ · F1-Gx + μ · Gy
= Μ ・ F1-G ・ cosα + μ ・ G ・ sinα
Here, the clamping force F1 is a force by which the clamping member 4b on the main plate 3 side presses the clamping member 4a on the base plate 2 side by the torsion coil spring 10, μ is a friction coefficient by the clamping members 4a and 4b, and Gx and Gy are paper Is the inclination angle from the bottom surface of the inclined portion 2a1.
As shown by the above formula, in the clip 1 of the present embodiment, the frictional force μ · Gy (that is, μ · G · sin α) due to the component force Gy perpendicular to the paper S at the weight G of the paper S is generated and the holding force is generated. Contribute to F. Here, in the case of a conventional clip in which the inclined portion 2a1 is not formed and the front side of the base 2 is flat, α = 0 °, so the paper S is held only by the frictional force μ · F1 due to the clamping force F1. Will be. Therefore, according to the clip 1 according to the present embodiment, the frictional force μ · Gy due to the weight G of the paper S also contributes to the holding force F of the paper S, so that the paper S can be held more reliably. Note that the above description in FIG. 6 describes one clamping portion P for the sake of simplicity.

  Furthermore, each clamping part P is provided with a clamping member 4a on the base 2 side as a clamping member, and a clamping member 4b on the main plate 3 side. Each clamping member 4a, 4b is formed of an elastomer as a soft elastic material. Accordingly, when the paper S is sandwiched, a large frictional force can be obtained. Thereby, even if the spring constant of the torsion coil spring 10 is lowered, the predetermined holding force F can be provided, so that the spring constant of the torsion coil spring 10 can be lowered and the opening / closing operation of the clip 1 can be made soft. The upper surface of the clamping member 4a on the base 2 side is a flat surface, and the clamping member 4b on the main plate 3 side is formed so as to project in a semicircular shape when viewed from the side. Therefore, when a plurality of sheets are sandwiched between the clips 1, even if the angle β between the main plate 3 and the base 2 is small, the holding member 4b on the main plate 3 side is always the same as in the case of holding one sheet. A substantially line contact with S is made. The back surface of the paper S is in surface contact with the upper surface of the clamping member 4a that is a flat surface. Accordingly, the sheet S can be received by the upper surface of the holding member 4a on the base 2 side while pressing the paper S with a high surface pressure by the holding member 4b on the main plate 3 side, so that even when a plurality of sheets are held, the paper 1 A frictional force equivalent to the case of sandwiching the sheets can be obtained.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by this embodiment, It can implement by adding a various change. For example, the base-side clamping part P1 and the main plate-side clamping part P2 may be provided with a clamping member made of a soft elastic material on at least one, or both may not be provided with a clamping member made of a soft elastic member. In the case where the clamping member is not provided, it is possible to form a slip stopper such as a concavo-convex groove in the base side clamping part P1 or the main plate side clamping part P2. Moreover, although the inclined part 2a1 of the base 2 is formed over the longitudinal direction, the inclined part can be formed only in the part of the base-side clamping part P1. In addition, in this embodiment, although the clamping part P was provided in two places, you may make it only one place and may make it provide three or more places.

  Further, the sandwiching members 4a and 4b are formed of an elastomer, but various other rubber materials such as silicon can be used as other soft elastic members. In the present embodiment, the clamping members 4a and 4b are provided on both the base 2 and the main plate 3, but a clamping member may be provided on either one of them. Moreover, in this embodiment, although the magnet 6 was used as an attraction | suction member, an attraction | suction member provided with the structure which latches a suction cup and a clip lower surface to a posting surface can also be used. Further, in the present embodiment, the torsion coil spring 10 is used as the urging means for urging the main plate 3 against the base 2, but other types of springs and other urging means can be used.
