Utility model registration 3056552

  The above-described connector (the bag for school bags) is characterized in that the attachment portion (1), the opening / closing portion (2), the hanging portion (4) and the like can be integrally formed of a resin material. However, the manufacturing method of the connection tool (the bag for school bags) is not specifically described. Therefore, in view of the fact that the opening / closing part (2) is bounced outward and is in contact with the locking part (3) at the tip of the suspended part (4), injection molding in this state is not possible. Since this is not possible, it can be inferred that injection molding is performed with the tip of the opening / closing part (2) positioned outside the locking part (3). In this case, operations such as pushing the opening / closing part (2) into the locking part (3) in a post-process after injection molding will be performed.

The present invention is provided at a position where the annular member abuts when the connected tool is suspended, a closing surface which holds the engagement of the annular member, and a position offset from a position opposed to the abutting surface, and the annular member approach path formed by the wire diameter substantially the same gap between the annular member, the possess, the annular member entryway includes a tip portion to which the extending curved from one side of the contact surface, the person A gap formed by a base portion extending linearly from the other side of the contact surface, and the annular member entry path is opposed to the protrusion formed in a convex curved shape from the tip portion, and the protrusion. A curved portion formed in a concave shape, and a protruding portion formed so as to project and be connected to the curved surface portion in a convex curved shape, and having a gap substantially the same as the wire diameter of the annular member formed To do.

  According to the present invention, as a connection tool for connecting a ring-shaped member such as a so-called round can, C-can, double round can (double ring) or neck strap and a tool to be connected (for example, writing instrument, mascot, etc.) Formed at opposite positions offset in the positional relationship between the abutment surface with which the annular member abuts when the tool is suspended and the approach path (annular member entry path) through which the annular member is inserted when the annular member is connected to the connection tool. doing. The annular member has a closed region formed by the contact surface and the closed surface, and the engaged state is maintained. Here, the region formed by the contact surface and the closed surface (closed region) is communicated with the outside by the annular member entry path, but the contact surface and the annular member entry path are at opposite positions. Therefore, the annular member does not fall off from the contact surface when suspended. Furthermore, since the annular member entry path is formed by a gap substantially the same as the linear shape of the annular member, it does not easily come off. With such a configuration, the connector according to the present invention can be formed not only integrally but also without post-processing after injection molding.

It is the figure which represented the to-be-connected tool and the connection tool with the cross section with respect to FIG.

  Embodiments of the present invention will be described below with reference to the drawings.

  In FIG. 1, the connector 1 is integrally formed of a resin material by injection molding or the like. The connector 1 is provided with a plate portion 2 formed in a long plate shape. On one side of the plate portion 2 (left side in FIG. 1), an engaging portion 10 that engages with the connected tool 100 (see FIGS. 4, 5, and 6) is formed. On the other side (right side in FIG. 1) of the plate part 2, a connection part 30 to which the annular member 40 (see FIG. 2) is connected is formed.

  The connecting portion 30 is formed with a base portion 31 extending in a thin plate shape from the substantially plane center portion of the plate portion 2. And the curved part 32 is formed so that it may be connected with the base 31 and it may curve to the plate part 2 side. Further, the first straight portion 33 is formed in parallel with the base portion 31 in a thin plate shape toward the plate portion 2 side so as to be connected to the bending portion 32. Further, a first bent portion 34 that is continuously provided from the first straight portion 33 and bent to the base portion 31 is formed. From the 1st bending part 34, the 2nd straight part 35 is formed in a straight line in a continuous manner. Then, the second straight portion 35 is further bent toward the base portion 31 and a second bent portion 36 is formed in a projecting manner (tip portion 37).

  The base portion 31 extending from the plate portion 2, and the curved portion 32, the first straight portion 33, the first bent portion 34, the second straight portion 35, and the second bent portion 36 connected to the base portion 31 are formed to have the same width. . The inclination angle of the first bent portion 34 is inclined from the first straight portion 33 toward the base portion 31 at an angle of approximately 45 degrees. Further, the second bent portion 36 is formed to be inclined from the second straight portion 35 to the contact surface 35 at an angle of approximately 60 degrees.

  Furthermore, a bulging portion 38 that bulges from the inner surface of the base portion 31 and the bending portion 32 is formed from the base portion 31 to the middle portion of the bending portion 32. At the starting end of the bulging portion 38 on the base portion 31, a protruding portion 38a is formed to protrude in a convex curved surface shape. The protruding portion 38a and the inner surface of the base portion 31 are connected by a curved surface portion 38b that is connected in a concave shape. On the other hand, a projecting portion 37a is formed in a convex curved shape from the distal end portion 37 which is the terminal end of the second bent portion 36 toward the projecting portion 38a and the curved surface portion 38b.

  The inner surface of the curved portion 32 is curved as a concave curved surface and is formed as a contact surface 39a described later. The contact surface 39a is a surface with which an annular member 40, which will be described later, contacts when the connected tool 100 is suspended. Furthermore, the annular member connected by the blocking surface 39b formed by the inner surface of the base 31 (the bulging portion 38) and the first straight portion 33, the first bent portion 34, the second straight portion 35, and the second bent portion 36. 40 will be blocked. On the other hand, the tip portion 37 and the base portion 31 form a gap having a distance S. Further, a gap of a distance T is formed between the protrusion 37a and the protrusion 38a. Therefore, the closed region formed by the contact surface 39a and the closed surface 39b communicates with the outside through the gaps of the distances S and T.

  The engaging portion 10 that engages with the connected tool 100 is formed to protrude from the plate portion 2 on the left side of FIG. 1 and is formed in a bent shape as a whole. One end of the engaging portion 10 is connected to the plate portion 2, and the other end is formed as a pressing portion 11. Since the whole connecting tool 1 is integrally formed by injection molding using a resin material or the like, the pressing portion 11 generates an elastic force upward by pushing down the pressing surface 12. Combined with this elastic force, the engaging protrusion 13 protruding from the upper surface engages with the engaging hole 105 (see FIG. 5) formed in the connected device 100, and the connected device is engaged. (Concatenated).

  Here, the to-be-connected tool 100 is demonstrated roughly with FIG. The connected tool 100 is a ballpoint pen. The to-be-connected tool (ballpoint pen) 100 presses the pressing portion 101a of the operation main body 101 formed in a substantially U shape with a finger, so that the cover main body 102 moves in a direction opposite to the pen tip 103a and the pen tip 103a is moved. It is a ballpoint pen that is ready for writing when exposed. When the pressing of the pressing portion 101a is released, the cover main body 102 moves forward due to the elastic force of the coil spring 104, and the pen tip 103a is immersed and put into a stored state.

  Next, a procedure for connecting the annular member 40 to the connector 1 will be described. In FIG. 3, the annular member 40 is represented by a cross section of a wire. As shown by the arrows in FIG. 3A, the annular member 40 follows the outer periphery of the first bent portion 34, the second straight portion 35, and the second bent portion 36, and includes a closed region 39 (abutment surface 39 a, closed block). Engaged in surface 39b).

  More specifically, the annular member 40 is passed through the clearance S (annular member entry path formed by the tip portion 37 and the base portion 31) (FIG. 3 (b)) and is made to follow the curved surface portion 38b (FIG. 3 (c). )) It is inserted into the closed region via the gap T (annular member approach path formed by the protrusion 37a and the curved surface part 38b) (FIG. 3 (d)). The gaps S and T are set to approximately the same size as the wire diameter of the annular member 40. However, when the annular member 40 is slightly larger due to a dimensional error, the first straight portion 33 is slightly bent. The gaps S and T are expanded.

  Thus, the connecting tool 1 to which the annular member 40 is connected can be connected to the connected tool (ballpoint pen) 100. That is, the engagement protrusion 13 in the engagement portion 10 of the connection tool 1 engages with the engagement hole 105 of the connection tool 100, whereby the annular member 40 can be easily connected to the connection tool 100. (See FIGS. 4, 5, and 6).

  Since the annular member 40 is coupled to the strap string 42 via the cylindrical member 41, the annular member 40 can be conveniently used for carrying the connected tool (ballpoint pen) 100.

  As shown in FIGS. 4, 5, and 6, when the connected tool 100 is carried, the annular member 40 comes into contact with the contact surface 39 a due to the weight of the connected tool 100. Even when the annular member 40 moves in the closed area 39 due to vibration or the like when being carried, the annular member entry path (gap S, T), which is the only communication part with the outside of the closed area, faces the contact surface 39a. Since it is formed at the offset position, the annular member 40 is not disconnected. In addition, since the gaps S and T are formed substantially the same as the wire diameter of the annular member 40, it is possible to prevent the gaps S and T from coming off more unexpectedly.

  Further, the protrusion 37a, and the clearance T (annular member entry path) formed by the curved surface portion 38b and the protruding portion 38a opposed to the protrusion 37a make it easy to insert the annular member into the closed region, but realize a structure that is difficult to come off. can do.

As mentioned above, although the Example of this invention was described in detail, this invention is not limited to this, In the range which does not change the summary of this invention, it can change suitably.
For example, the annular member 40 is illustrated as a round can in the drawing, but may be another annular member such as a C can or a double round can (double ring). Similarly, the annular member 40 can be implemented by implementing the present invention with a neck strap formed by a string-like member. Moreover, although the connection tool 1 shall be formed detachably with the to-be-connected tool 100, it may be fixed to a to-be-connected tool, or the connection part 30 is integrally injection-molded to a to-be-connected tool. It may be a connector configured as described above.
