Description

  The present invention relates to a connector for connecting a card holder for accommodating a name tag or a business card for identifying an individual at a workplace, a conference hall or the like to a strap or a clip.

  In recent years, with the advancement of technology and information, companies have restricted access to outsiders in the office or established areas where only employees belonging to specific departments can enter and exit to strive to maintain internal secrets. A lot is happening. For one of the purposes of determining whether such access is possible, employees or visitors are required to carry a card holder containing a name tag or the like.

In a conference hall or exhibition hall where many people gather, in order to identify an individual or introduce himself / herself, a card holder containing a name tag or the like is usually hung from the neck.
Such a card holder is generally connected to a clip for fixing to a strap for a neck or a breast pocket via a connector.
The connector is made of a metal eggplant or the like that has a metal hook attached to a synthetic resin belt and is folded in two (Patent Document 1, Non-Patent Document 1), or a composite that has a hook and is folded in two. There is a resin alone (Patent Document 1, Non-Patent Document 2). In addition, a clip for clothes such as a name tag, which is manufactured only from an elastic resin material such as polyacetal and is folded in two and connected to a card holder, has been proposed (Patent Document 2).

The connector 1 includes a belt portion 11, a protrusion 12, a hole 13, a strap attachment portion 14, and the like.
The belt portion 11 is a main body portion of the connector 1 in a belt shape (band shape) having a small thickness and a wide width. The belt portion 11 has a predetermined length, and except for a specific range 15 inward in the longitudinal direction, one surface is thicker as it goes inward in the width direction of the cross-sectional arch shape (arc shape). Is formed.

The surface of the belt portion 11 that is curved in an arch shape is referred to as “back surface 16”, and the opposite surface is referred to as “front surface 17”. The front surface 17 is a surface that becomes the inner side when the connector 1 is folded in half. The specific range 15 that is not the meat pressure in the belt portion 11 is referred to as a “bend portion 15”.
The belt portion 11 has a total length of about 45 mm and a width of about 12 mm. The thickness of the bent portion 15 is about 0.8 mm, and the other portions of the belt portion 11 have a thickness of about 1.2 mm at the center in the width direction and a thickness of 0.8 mm at the end in the width direction. .

The belt portion 11 has a semicircular shape at one end in the longitudinal direction. The width of the belt portion 11 gradually decreases from the bent portion 15 to the semicircular end. The other end in the longitudinal direction of the belt portion 11 is continuous with the strap attachment portion 14.
The projecting portion 12 is a portion projecting perpendicularly to the front surface 17 from the front surface 17 of the belt portion 11 in the vicinity of the end opposite to one end in the longitudinal direction, which is semicircular in shape. . Referring to FIGS. 1 and 3, the protrusion 12 includes a base 21, a first locking part 22, a second locking part 23, a bottom part 24, and respective intermediate parts in order in the protruding direction. The protrusion 12 is hollow, and the protruding end is closed by the bottom 24. The protrusion 12 has a circular shape in any portion of the cross section perpendicular to the protruding direction.

The base portion 21 is a portion that makes the protrusion 12 continue to the belt portion 11. The base portion 21 is thicker than the belt portion 11.
The 1st latching | locking part 22 is a part located in the middle of the protrusion direction where the outer diameter of a cross section becomes the largest except for the base 21 in the protrusion 12. FIG. The first locking portion 22 is an annular curved surface whose surface is arcuate in a cross section including the axial center of the protrusion 12 and is convex outward. The 1st latching | locking part 22 continues to the base 21 by the intermediate part which is the cyclic | annular curved surface which became the inward convex.

The second locking portion 23 is continuous with the first locking portion 22 through an intermediate portion having a constant outer diameter, and has a larger outer diameter than the above-described intermediate portion located in the vicinity of the protruding end of the protruding portion 12. Part. The surface of the second locking portion 23 is an annular curved surface that has an arc shape in a cross section including the axis of the protrusion 12 and is convex outward.
As described above, the bottom 24 closes the projecting end of the projecting portion 12 that is hollow.

  A hollow portion of the protrusion 12 is referred to as a hollow hole 25. The hollow hole 25 is open to the back surface 16, and its shape is a truncated cone having a small inner diameter on the protruding end side on the back side. The hollow hole 25 has a cross section in which the inner diameter suddenly increases toward the opening on the opening side, and the inner peripheral surface includes the axial center of the protrusion 12 like the shape of the sound trumppet sound (bell) of the musical instrument. At the inward convex curve.

The hole 13 is located in the vicinity of the end where the shape of the belt 11 is semicircular. The hole 13 includes a hole 31 penetrating from the front surface 17 side to the back surface 16 side, and a portion surrounding the hole 31 (hereinafter referred to as “hole peripheral portion 39”). The hole portion 13 has a thickness T larger than that of the belt portion 11. The thickness T of the holes 13 is approximately equal to the hole 31 protruding height H, that is, the projection height H except for the base portion 21 of the projection 12 is a cross-sectional the shape is a circle of any part of its axial direction . The hole 31 is a curved surface convex inward in the radial direction in the vicinity of the opening on the front surface 17 side. Further, in the cross section including the central axis, the tangent of the opening end (the end on the most front surface 17 side in the central axis direction in the cross section) of the hole 31 is orthogonal to the central axis, and therefore the inner diameter sharply increases toward the opening. To increase. The hole 31 has an engaging portion 32 on the back side (back surface 16 side) of the curved surface.

The engaging part 32 is an arcuate curved surface having an inner diameter larger than that of the other part in an arc shape that is concave in the radial direction in the cross section including the central axis of the hole 31. When the section including the central axis is overlapped with the cross section including the axis of the first locking part 22, the engaging part 32 can accommodate the first locking part 22 on the inside thereof, or the contour of the inner surface thereof. However, it overlaps with the contour of the outer surface of the first locking portion 22 or slightly smaller than the contour of the outer surface of the first locking portion 22.

  Further to the back of the engaging portion 32 (on the back surface 16 side), a small diameter portion 33 having an inner diameter smaller than the engaging portion 32 and a constant inner diameter in the penetrating direction, and a diameter larger than the small diameter portion 33 and a constant inner diameter. Most of 34 are connected. The small-diameter portion 33 and the large-diameter portion 34 are divided by a step 35 whose inner diameter changes discontinuously. Here, the step 35 means a surface facing the back surface 16 side, which is generated by discontinuously changing the inner diameter.

The distance D1 between the position where the inner diameter of the engaging portion 32 is maximized in the direction of the central axis of the hole 31 and the step 35 is set so that the outer diameter of the first locking portion 22 is maximized in the protruding direction of the protruding portion 12. Is approximately equal to a distance D2 from the position to the second locking portion 23 (the end on the first locking portion 22 side) (FIG. 3).
The inner diameter of the small-diameter portion 33 is substantially equal to or slightly larger than the outer diameter of the intermediate portion of the protrusion 12 between the first locking portion 22 and the second locking portion 23. The inner diameter of the large diameter portion 34 is substantially equal to or slightly larger than the maximum outer diameter of the second locking portion 23 of the protrusion 12. The large diameter portion 34 has a larger inner diameter in the vicinity of the opening to the back surface 16.

In the hole 31, the distance D3 between the center axis of the hole 31 and the end 36 on the hole 31 side of the bent portion 15 is substantially equal to the distance D4 between the axis of the protruding portion 12 and the end 26 on the protruding portion 12 side of the bent portion.
In the vicinity of the hole 13 on the front surface 17 side, a reinforcing ring 37 and a plurality of ribs 38 are provided. The reinforcing ring 37 is an annular portion that protrudes toward the front surface 17 and surrounds the hole 13 with a space from the hole 13. The reinforcing ring 37 has a width and height of around 1 mm. The rib 38 is a linear portion that starts from the hole peripheral portion 39 and extends radially from the center of the hole 31 and protrudes toward the front surface 17. Six ribs 38 extend at an interval of 60 degrees in the circumferential direction so as to intersect the reinforcing ring 37 and extend radially outward. Each rib 38 is continuous with the reinforcing rib 41 when a later-described reinforcing rib 41 exists on the extension line, and the other ribs 38 end extending radially outward from the reinforcing ring 37 by about 0.5 mm. The width and height of each rib 38 is approximately 1 mm.

  The six ribs 38,..., 38 are provided corresponding to the position of the tip of an ejector pin (ejector pin) when the connector 1 molded from a resin material is removed from the mold, and protrudes when removed from the mold. By the pins projecting any one of the ribs 38, deformation of the connector 1 immediately after molding is prevented. The number and position of the ribs 38 can be changed according to the arrangement of the protruding pins. Further, the rib 38 may be omitted by making the position of the reinforcing ring 37 coincide with the position of the protruding pin.

Reinforcing ribs 41 are provided on one edge of the belt portion 11 in the longitudinal direction and the edge in the vicinity thereof. The reinforcing rib 41 has a thickness of approximately 0.8 mm, and protrudes outward while being orthogonal to the front surface 17 along a semicircular edge or the like. The reinforcing rib 41 extends not only to the semicircular end edge but also to the inner end edge in the longitudinal direction of the belt portion 11 that overlaps with the hole portion 13 (hole peripheral portion 39) in FIG. That is, the reinforcing rib 41 is provided so as to surround the hole 13 from three sides except for the protrusion 12 side. The reinforcing rib 41 has a protruding height of about 2 mm. Reinforcing ribs 41 are longitudinal projection height is Oite gradually height is low at an inner end of the belt portion 11 is 0 mm.

The strap attachment portion 14 is continuous with the other end in the longitudinal direction of the belt portion 11 (the end opposite to the semicircular end). The strap attachment portion 14 has the same width as the belt portion 11 and is approximately 3 mm thicker than the belt portion 11. The strap attaching portion 14 projects most of the difference in thickness with the belt portion 11 toward the front surface 17 side.
The strap attachment portion 14 includes a strap hole 42 penetrating the front surface 17 side and the back surface 16 side. The strap hole 42 is a rectangle whose cross-sectional shape has a short side in the longitudinal direction of the belt portion 11. Reinforcing walls 43, 43 that gradually increase in height from the front surface 17 to the projecting surface of the strap hole 42 at both ends in the width direction of the belt portion 11 at the portion where the strap attachment portion 14 and the belt portion 11 are continuous. Is provided. The thickness of the reinforcing wall 43 is substantially equal to the thickness of the reinforcing rib 41.

The connector 1 is made of an olefin-based synthetic resin such as polyethylene (PE) or polypropylene (PP).
Next, the connection between the card holder 2 and the strap 3 by the connector 1 will be described.
FIG. 4 is a diagram illustrating a state in which the connector 1 connects the card holder 2 and the strap 3.
The coupling 1 and the strap 3 are connected by passing the strap 3 through the strap hole 42. The straps 3 are connected to each other by a buckle that can be separated from each other, or are connected so as not to be separated by caulked metal or the like. The strap 3 here is a so-called flat string.

  Subsequently, the hole 13 side end of the connector 1 is passed through a strap attachment hole provided in the card holder 2 (hereinafter referred to as “attachment hole 51”). The connector 1 having one end passed through the mounting hole 51 is folded in two at the bent portion 15 with the front surface 17 facing inward, and the protrusion 12 is fitted into the hole 31. The bent portion 15 has a small thickness in the belt portion 11 and can be easily folded in two. The protrusion 12 fitted in the hole 31 is held by the first locking portion 22 being fitted into the engaging portion 32 of the hole 31, and the convex curved surface of the second locking portion 23 is the hole. It is latched by the step 35 of 31 (refer the dashed-two dotted line part of FIG. 3).

The connector 1 is connected to the card holder 2 mainly by fitting the first locking portion 22 and the engaging portion 32, and the second locking portion 23 is locked by the step 35. Maintained.
The connector 1 connects the card holder 2 by sandwiching the belt hole 11 folded in half between the mounting hole 51 in the card holder 2 and its nearest edge. Since the connector 1 is already connected to the strap 3, the connector 1 connects the card holder 2 and the strap 3.

The width of the belt portion 11 gradually decreases from the end 36 on the hole 13 side of the bent portion 15 to the semicircular end. Therefore, in a state in which the protrusion 12 is fitted in the hole 31, the tip end side of the semicircular end is positioned between these two layers without overlapping the two reinforcing walls 43 and 43.
To remove the card holder 2 from the connector 1, the projecting portion 12 is extracted from the hole 31 by pinching the semicircular end side of the belt portion 11. When the protrusion 12 is extracted from the hole 13, both ends of the belt portion 11 are opened, and the card holder 2 is taken out from the connector 1.

The protrusion 12 can be extracted from the hole 31 mainly by deformation of the elastic resin that forms the protrusion 12.
As a material forming the connector 1 having elasticity, a synthetic resin in which polyethylene and polypropylene are mixed at a certain ratio so that appropriate elasticity and strength are harmonized and suitable for production is used. The

  By the way, even if the resin material has elasticity, if the deformation is large, the resin material is damaged. The connector 1 is provided with a hollow hole 25 in the protrusion 12 to facilitate the deformation, and on the other hand, by providing a bottom 24 that closes the hollow hole 25 at the protruding end of the protrusion 12, excessive deformation of the protrusion 12 is suppressed. To do. The connector 1 has a hollow hole 25 whose tip is closed at the protrusion 12, so that the deformation of the protrusion 12 when the protrusion 12 is extracted from the hole 31 can be prevented from being damaged. Can fit in.

  If the protrusion 12 is solid without forming the hollow hole 25 in this way, the protrusion is difficult to deform. Therefore, when the protrusion and the hole 13 are separated from each other, the deformation of the hole 13 becomes large, and the hole Damage is likely to occur around the portion 13. Further, when the protrusion 12 is a hollow hole having no bottom 24, the protrusion is excessively deformed when the protrusion and the hole 13 are separated, and the periphery of the protrusion (for example, the base of the protrusion) is damaged. easy. The bottom 24 of the protrusion 12 has a function of appropriately increasing the rigidity of the hollow protrusion 12 and preventing damage around the hole 13 and the protrusion 12 when the protrusion and the hole 13 are separated.

Further, in the connector 1, the periphery of the hole 31 is reinforced by making the periphery of the hole 31 (hole peripheral portion 39) thicker than the belt portion 11. The reinforcement around the hole 31 prevents excessive deformation of the hole 31 and prevents breakage around the hole 31 even if the work is forcibly performed when the protrusion 12 is extracted from the hole 31.
Furthermore, since the reinforcing rib 41 is provided near the tip of the belt portion 11 on the hole 13 side, the periphery of the hole 13 is further reinforced. The operation of extracting the protrusion 12 from the hole 31 is performed by pinching the end on the side not connected to the strap 3, that is, the end on the hole 13 side. The area around the portion 13 is not excessively deformed, and damage around the hole 13 is prevented.

  On the other hand, in the connection tool described in Patent Documents 1 and 2 that do not have the reinforcing rib 41, and the connection tool in Non-Patent Document 2, it is pinched in the release operation of the connection that is performed by pinching the end on the hole side. The end side warps and deforms greatly. The connection tool described in these is easily damaged around the hole due to this excessive deformation when the connection between the hole and the protrusion is released. The reinforcing rib 41 works to avoid damage around the hole 13 by increasing the rigidity around the hole 13 and preventing warping from the hole 13 to the semicircular tip in the release operation of the connection. .

The rigidity around the hole 13 is also increased by the reinforcing ring 37 that surrounds the hole 13, and the hole 13 is prevented from being excessively deformed by the reinforcing ring 37 and prevented from being damaged.
It is preferable that the connector 1 has an appropriate hardness for both the operation of fitting the protrusion 12 into the hole 31 and the operation of extracting the protrusion 12 from the hole 31 (releasing the connection). This appropriate hardness depends on the combination of the dimensions of the protrusion 12 and the hole 31 (hole 13), but also varies depending on the elasticity of the resin that is the material.

FIG. 5 is a view of another form of connector 1B. 5A is a perspective view of the connector 1B as viewed from the side that is folded in half, FIG. 5B is a cross-sectional view taken along the line B-B of FIG. 5A, and FIG. It is a figure which shows a mode that 2 and the strap 3 are connected.
The connector 1B includes a belt portion 11B, a protruding portion 12B, a hole portion 13B, a strap attaching portion 14, and the like. Strap portion 14 in the connector 1B is the same as in connector 1 is omitted given the description thereof the same sign-the connector 1 in FIG.

  The belt portion 11B is different from the belt portion 11 in the connector 1 in that the end opposite to the side continuous with the strap attaching portion 14 is based on a shape having two apex angles of 90 degrees instead of a semicircular shape. Different. An edge (two corner portions) corresponding to a 90-degree apex angle is curved for corner removal. The structure of the other part of the belt part 11B is the same as that of the belt part 11 in the connector 1.

  Since the end of the belt portion 11B opposite to the side continuous with the strap attaching portion 14 has a shape having two apex angles of 90 degrees (trapped), the connector 1B extends along this edge. The reinforcing rib 41B is also provided in accordance with this shape (see FIG. 5A). The reinforcing rib 41B extends from the tip of the hole 13B toward the protrusion 12B to a position overlapping the hole 13B when the connector 1B is viewed from the width direction of the belt 11B. This also applies to the reinforcing rib 41 in the connector 1.

  The protrusion 12B includes a base 21, a first locking part 22, a constant diameter part 27B, a bottom 24, and respective intermediate parts in order in the protruding direction. The projecting part 12B is a connecting tool 1 in that it is a constant diameter part 27B having a constant outer diameter from the first locking part 22 to the protruding end, that is, the second locking part 23 is not provided. It differs from the protrusion 12 in FIG. The structure of the other part of the protrusion 12B is the same as that of the protrusion 12 in the connector 1.

  The hole 13B includes a hole 31B penetrating from the front surface 17 side to the back surface 16 side, and a hole peripheral portion 39 surrounding the hole 31B. The hole 31B includes an engaging portion 32 at the back of the opening on the front surface 17 side and a small-diameter portion 33B on the back surface 16 side. In the connector 1B, the large diameter portion and the step as in the hole 31 of the connector 1 are not provided in the hole 31B, and the small diameter portion 33B continues to the vicinity of the opening on the back surface 16 side. Except for these points, the hole 13 </ b> B has the same configuration as the hole 13 in the connector 1.

  The connector 1 </ b> B does not include the reinforcing ring 37 included in the connector 1. Further, the connector 1B extends radially from the rib peripheral portion 39 with three ribs 38 at intervals of 120 degrees. Each rib 38 continues to the reinforcing rib 41B when the reinforcing rib 41B is present on the extension line, and extends outward in the radial direction by about 2 mm when the reinforcing rib 41B does not exist on the extension. Each rib 38 has a width of 1.5 mm and a height of about 1 mm.

For connector 1B, portions not described, the portion having a sign-in common with the sign of the connector 1 in FIG. 5, the configuration is assumed in connector 1 is the same.
The connection between the card holder 2 and the strap 3 by the connecting tool 1B is performed in the same manner as in the connecting tool 1.
Since the protrusion 12B includes the hollow hole 25 and the bottom 24, the connector 1B is deformed particularly when the protrusion 12B is extracted from the hole 31B, so that excessive deformation is suppressed. As a result, in the connector 1B, damage around the protrusion 12B can be prevented, and a moderate release feeling (appropriate hardness) can be given to the operator while reducing fatigue that leads to breakage.

Further, the connecting tool 1B has the reinforcing rib 41B in the vicinity of the tip on the hole 13B side, so that the rigidity around the hole 13B is increased, and the hole 13B is excessively moved in the releasing operation of the hole 13B and the protrusion 12B. It is not deformed and damage such as tearing in the vicinity of the hole 13B is prevented.
The hole 31 may be closed without opening the back surface 16. In the couplers 1, 1 </ b> B, the protrusions 12, 12 </ b> B are appropriately deformed when the connection between the protrusions 12, 12 </ b> B and the holes 13, 13 </ b> B is released. Is prevented. Such an effect is not affected by whether or not the hole 31 penetrates.

  Further, the reinforcing ribs 41 and 41B are long as a whole so as to prevent excessive warping on the side of the holes 13 and 13B when the connection between the protrusions 12 and 12B and the holes 13 and 13B is released. As long as it extends in the direction, other forms can be adopted. For example, the reinforcing rib 41C may be formed so as to extend in the longitudinal direction inward in the width direction from the longitudinal edges of the belt portions 11 and 11B (FIG. 6A), or about the holes 13 and 13B. Reinforcing ribs 41D may be formed so that the distance between the belt portions 11 and 11B in the width direction is gradually reduced toward the tip from the both sides in the width direction (FIG. 6B).

In the above-described embodiment, a part of the configuration of the connector 1 and a part of the configuration of the connector 1B can be combined to form another type of connector. The shapes of the first locking part 22, the second locking part 23, the engaging part 32, the hole peripheral part 39, the reinforcing ring 37, the reinforcing ribs 41 and 41B, the strap attaching part 14 and the like in the couplers 1 and 1B are as follows. It can be arbitrary within the scope of the invention.
In addition, each structure of the coupler 1,1B and the coupler 1,1B or the overall structure, shape, dimensions, number, material, and the like can be appropriately changed in accordance with the spirit of the present invention.

  INDUSTRIAL APPLICABILITY The present invention can be used as a connection tool for connecting a card holder that accommodates a name tag or a business card for identifying an individual at a workplace, a conference hall or the like to a strap or a clip.
