DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0074] Next, the embodiment of the present invention will be described with reference to the drawings.
[0075] In this specification, a coordinate axis is used to describe the shape of the clip 1 and the pin 10. The vertical direction of the center axis of the pin 10 is taken to be the Z direction; the direction of the straight line part 11a of the pin flange 11 perpendicular to the Z direction is taken to be the x direction; and the direction perpendicular to the x direction is taken to be the y direction.
[0076] As shown in
[0077] As shown in
[0078] A plurality of pin leg parts 14 extend downwards from around the pin flange hole 12 of the pin flange 11. In the embodiment of the present invention, there are 3 pin leg parts 14. The pin leg parts 14 extend downward from 3 alternating sides of the hexagon shape of the pin flange hole 12. There must be a plural number of pin leg parts 14, but this is not restricted to 3 legs. The shape of the pin flange hole 12 will also change depending on the number of pin leg parts 14. There are intervals in the circumferential direction between adjacent pin leg parts 14 that extend downwards from 3 alternating sides of a hexagonal shape. The upper end of each of the pin leg parts 14 is joined to the pin flange 11 so that the pin leg parts can each independently bend in the radial direction. There is a hollow spacing at the center part of the plurality of pin leg parts 14. The bushing leg part 25 of the bushing 20 fits into this hollow.
[0079] As shown in
[0080] As shown in
[0081] A second lock 17 is formed near the center between the pin flange 11 and the first lock 16 of the pin leg grooves 18 on the outer surface of each pin leg part 14. The second lock 17 is also a shape protruding outwards in the radial direction from the pin leg grooves 18 that engages with the flange hole protruding parts 29 of the bushing 20 for a permanent locked state.
[0082] As shown in
[0083] The first lock 16 and the second lock 17 do not extend beyond the outer surface of the pin leg parts 14, enabling smooth insertion of the pin leg parts 14 into the bushing flange holes 23 of the bushing 20.
[0084] As shown in
[0085] When the pin leg parts 14 are pushed downward, the pin leg tip parts 15 contact the bushing leg spreading part 27 of the bushing 20, causing the pin leg parts 14 to spread. The outer surfaces of the pin leg tip parts 15 have a sloped surface part 15a for easy insertion into the bottom hole 36 of the holding piece lower part 35 of the bushing 20.
[0086]
[0087]
[0088] The direction of the center axis of the bushing 20 is taken to be the Z direction; the direction of the upper holding pieces 32a and of the lower holding pieces 32b is taken to be the x direction; and the direction perpendicular to the x direction is taken to be the y direction.
[0089] As shown in
[0090] The bushing flange 21 has a diameter that is larger than the pin flange 11. A flange recess part 22 is formed in the upper surface of the bushing flange 21, enabling stowing of the pin flange 11. The inner diameter of the flange recess part 22 is slightly larger than the outer diameter of the pin flange 11. The depth of the flange recess part 22 is slightly larger than the thickness of the pin flange 11, and the pin flange 11 is set inside the flange recess part 22 when the clip 1 is in the permanent locked state. The depth of the flange recess part 22 can be roughly equivalent to the thickness of the pin flange 11. The flange recess part 22 can be omitted.
[0091] As shown in
[0092] As shown in
[0093] As shown in
[0094] The lower part of the bushing flange holes 23 has three bushing leg recess parts 26 formed in the vertical direction to receive the three pin leg parts 14.
[0095] As shown in
[0096] A step part 27a is provided with a step formed at the tip of the bushing leg spreading part 27. In a permanent locked state, the pin leg tip parts 15 of the pin leg parts 14 engage with the spread parts step parts 27a, preventing removal.
[0097] As shown in
[0098] As shown in
[0099] A pair of flange locking tabs 24 is provided adjacent to the flange openings 28 on the bottom surface of the bushing flange 21. As shown in
[0100] The pair of flange locking tabs 24 is adjacent to the pair of holding piece retention parts 31. When the pair of upper holding pieces 32a and lower holding pieces 32b are folded as described below, the bottom protruding part 37 engages with the flange locking tab 24.
[0101] As shown in
[0102] The pair of holding piece retention parts 31 extend in the Y direction. As shown in
[0103] The holding piece lower part 35 is connected between the pair of lower holding pieces 32b via the third hinge 33c. The length of the holding piece lower part 35 in the x direction is roughly equivalent to the spacing between the pair of holding piece retention parts 31. As shown in
[0104] The pairs of holding piece retention parts 31 and upper holding pieces 32a are connected by the first hinge 33a, the upper holding pieces 32a and lower holding pieces 32b are connected by the second hinge 33, and the lower holding pieces 32b and holding piece lower part 35 are connected by the hinge 33c; therefore enabling the second hinge 33b to expand outwards, the holding piece lower part 35 to move upwards and thus deform into the shape of a pantograph.
[0105] A bottom hole 36 is formed in the center part of the holding piece lower part 35. The bottom hole 36 is sized so as to enable the bushing leg part 25 to pass through. As the upper holding pieces 32a and lower holding pieces 32b fold, the holding piece lower part 35 remains level as it moves upward. The bushing leg part 25 passes through the bottom hole 36 protruding beneath the holding piece lower part 35. The upper holding pieces 32a and lower holding pieces 32b fold, so the bushing leg part 25 passes through the bottom hole 36 and the upper holding pieces 32a and lower holding pieces 32b fold together without disturbing the pantograph shape. As the upper holding pieces 32a and lower holding pieces 32b fold together, the second hinge 33b expands to the outside.
[0106] As shown in
[0107] A pair of bottom protruding parts 37 are formed at the lower part of the flange opening 28 at the part opposite the holding piece lower part 35. The pair of bottom protruding parts 37 protrudes in the y direction. When the pair of upper holding pieces 32a and lower holding pieces 32b are folded the bottom protruding part 37 engages with the flange locking tab 24, enabling retaining of the permanent locked state.
[0108]
[0109] In
[0110] The three pin leg parts 14 of the pin 10 are inserted into the three bushing flange holes 23 formed in the bushing flange 21 of the bushing 20 to set the pin 10 and the bushing 20 in a temporary locked state. The three pin leg parts 14 move downward along the bushing leg recess parts 26 of the bushing leg part 25.
[0111] As shown in
[0112] The pin 10 and the bushing 20 are in temporary locked state in this position.
[0113] In the temporary locked state, the first lock 16 of the pin leg parts 14 engages with the flange hole protruding parts 29 of the bushing 20, stopping the pin 10 from being pulled out. Also, the pin leg tip parts 15 of the pin leg parts 14 come into contact with the bushing leg spreading part 27; this opposes the push force on the pin 10, maintaining the temporary locked state.
[0114] As shown in
[0115] We shall now describe the method of first attaching the clip 1 in temporary locked state to a mounting member 51. The mounting hole 53 of the mounting member 51 is sized to enable the holding piece lower part 35 to pass through, cause narrowing of the spacing of the second hinge 33b, enabling the upper holding pieces 32a and lower holding pieces 32b to pass through, and the pair of holding piece retention parts 31 to fit into the mounting hole 53. The mounting hole 53 can have the shape of a square, a rectangle, a circle or the like.
[0116] The clip 1 of
[0117] Next, the holding piece lower part 35 is pushed up, folding the upper holding pieces 32a and the lower holding pieces 32b. As the upper holding pieces 32a and lower holding pieces 32b fold, the upper surface of the upper holding pieces 32a comes into contact with the bottom surface of the mounting member 51.
[0118]
[0119] As shown in
[0120] As shown in
[0121] Thus, the clip 1 is first attached to the mounting member 51.
[0122]
[0123]
[0124] We shall now describe the method of mounting the clip 1 to the member to be mounted to 50. The pin leg parts 14 and the bushing leg part 25 of the clip 1 mounted to the mounting member 50 are inserted into the mounting hole 52 of the member to be mounted to 50. The mounting hole 52 of the member to be mounted to 50 is sufficient if the tip of the bushing leg part 25 of the clip 1 in a temporary locked state and the pin leg tip parts 15 of the pin leg parts 14 can pass through.
[0125] The bottom surface of the lower holding pieces 32b and the bottom surface of the holding piece lower part 35 come into contact with the member to be mounted to 50, stopping the clip 1. Next, when the pin flange 11 of the pin 10 is pushed into the flange recess part 22 of the bushing flange 21, the pin leg parts 14 are pushed against the bushing leg spreading part 27 of the bushing leg part 25 and are spread. As shown in
[0126] Also, the second lock 17 of the pin leg parts 14 engages with the flange hole protruding parts 29 of the bushing flange 21, stopping the pin 10 from being pulled out.
[0127] The member to be mounted to 50 is sandwiched and secured between the pin leg parts 14 that are spread, the holding piece lower part 35, and the lower holding pieces 32b.
[0128] Thus, the clip 1 is permanently locked, and the mounting member 51 is attached to the member to be mounted to 50.
[0129] For removal of the clip 1 from the member to be mounted to 50, the tip of a screwdriver or the like is placed between the straight line part 11a of the pin flange 11 and the bushing flange recess part 22 in
[0130] We shall next describe removal of the bushing 20 from the mounting member 51. Upon disengaging the bottom protruding part 37 of the holding piece lower part 35 and the flange locking tab 24 of the flange opening 28 using the tip of a screwdriver or the like, the folded upper holding pieces 32a and lower holding pieces 32b can return to the shape of a pantograph. Upon pushing so that the second hinges 33b become closer to each other, the bushing 20 can be removed from the mounting hole 53 of the mounting member 51.
[0131] The pin 10 and the bushing 20 thus removed can be used again.
[0132] The clip 1 made up of a pin 10 and the bushing 20 according to this embodiment of the present invention can first be attached to a mounting member 51, such as an undercover or the like and then attached to the member to be mounted to 50, such as an automotive panel or the like. Furthermore, after the pin 10 and the bushing 20 are removed, they can be used again.
[0133] It will be appreciated by persons skilled in the art that the above embodiments have been described by way of example only, and not in any limitative sense, and that various alterations and modifications are possible without departure from the scope of the invention as defined by the appended claims.
