- FIGS. 1 - 9 illustrate Embodiment 1 of the present invention and, as shown by FIG. 1, a simple fastening device 1 comprises a base 2 , a running screw 2 , a cover 4 , and a spring piece 5 .
- a bolt 6 (FIGS. 5 - 9 ) is inserted into the base 2 , and a bolt-insertion hole 7 penetrates through the base in an axial direction as shown by FIG. 2.
- a bolt-insertion face, into which the bolt 6 is inserted, is illustrated as 2 a in FIG. 1.
- a moving groove 2 b is formed inside the base 2 .
- the moving groove 2 b is designed in such a manner that a below-described running screw 3 moves therein, and the moving groove 2 b is formed in such a way that the diameter of the bolt-insertion hole 7 varies in a prescribed way.
- a slope portion 8 is formed on the side of the bolt-insertion face 2 a of the moving groove 2 b.
- the slope portion 8 is formed into a conical shape whose diameter is gradually reduced toward the bolt-insertion face 2 a , in a manner so as to match the bolt-insertion hole 7 .
- the slope portion 8 supports the running screw 3 in such a way that the running screw 3 can slide, and the slope portion 8 is formed into a shape that fits along the outer profile of the running screw 3 . Accordingly, when the running screw 3 moves along the slope portion 8 , a female screw 3 a (which will be described later and which is shown in FIGS. 1 ( a ), ( b ), and ( c ) and in FIGS. 3 ( b ), ( c ), and ( d )) of the running screw 3 that engages with the outer surface of the bolt 6 moves in a horizontal direction.
- the inner face of the bolt-insertion hole 7 which is opposed to the moving groove 2 b (the running screw 3 ), is an arc-shaped bolt-receiving face 9 having approximately the same curvature as that of the bolt 6 .
- the bolt-receiving face 9 receives the reaction force generated when the running screw 3 is engaged with the bolt 6 , thereby securely fastening the bolt 6 .
- a cover-attaching concavity 2 c is formed on the end face of the base 2 on the opposite side of the bolt-insertion face 2 a .
- the cover-attaching concavity 2 c is formed in a noncircular shape and, in this embodiment, it is formed into a noncircular shape with parallel cuts on two sides.
- the base 2 in this embodiment is molded so as to have a hexagonal nut-like outer profile, but it is not limited to this shape, and it can also be formed into other shapes.
- the running screw 3 has a split shape that is obtained by splitting a circular column shape into plural pieces along the direction of its diameter.
- a female screw 3 a that engages with a male screw 6 a on the outer surface of the bolt 6 .
- a slide face 3 b which is formed into a conical tapered shape and which slides on the slope portion 8 , is formed at the bottom of the running screw 3 .
- one running screw 3 is used, and it is inserted in the base 2 in a manner so that the female screw 3 a of the running screw 3 is opposed to the bolt-receiving face 9 , in order to fasten the bolt 6 between the running screw 3 and the bolt-receiving face 9 .
- the cover 4 is fit into the cover-attaching concavity 2 c of the base 2 so as to close the face that is opposite to the bolt-insertion face 2 a of the base 2 .
- the cover 4 as shown in FIG. 4, is formed into a noncircular outer profile that is similar to that of the cover-attaching concavity 2 c , and an insertion hole 4 a , through which the bolt 6 penetrates, is formed at the center of the cover 4 .
- the cover 4 clamps the end face of the base 2 and is thereby affixed to the base 2 .
- a spring piece 5 and a guide projection 10 that constitutes a guide means are formed on such a cover 4 .
- One part of the cover 4 is bent toward the side of the base 2 , so that elasticity is given to the spring piece 5 .
- the spring piece 5 acts as a pressing means for pressing the running screw 3 , which is inserted in the base 2 , downward.
- the spring piece 5 is integrated with the cover 4 , and the number of parts that constitute a simple fastening device is reduced, resulting in easy assembly, which is advantageous.
- the guide projection 10 is formed on the cover 4 on the side of the spring piece 5 .
- the guide projection 10 is formed in a manner so as to project toward the base 2 (the insertion side of the bolt 6 ) from both sides of the spring piece 5 .
- the guide projection 10 is formed into a triangular piece that protrudes downward, and it has a guide face 10 a that is inclined in the same direction as the slope portion 8 of the above-mentioned base 2 .
- Guide grooves 11 constituting a guide means, together with the guide projections 10 , are formed on the running screws 3 . As shown in FIG. 3, the guide grooves 11 are provided on both sides of the top face of the running screw 3 and are engaged with the guide projections 10 . This engagement of the guide projections 10 and the guide grooves 11 prevent the running screw 3 from slipping down.
- FIGS. 5 - 9 illustrate the action of this embodiment.
- a running screw 3 is inserted into the moving groove 2 b of the base 2 in a manner so that a female screw 3 a is opposed to the bolt-receiving face 9 of the bolt-insertion hole 7 .
- the running screw 3 is supported by the slope portion 8 .
- both ends of the running screw 3 which are perpendicular to the axial direction of the running screw 3 , are brought into contact with and fastened to the inner face of the base 2 , and thus the running screw 3 is prevented from falling out of the base 2 .
- both ends of the running screw 3 which are perpendicular to the axial direction of the running screw 3 , protrude inside the bolt-insertion hole 7 (see FIG. 1).
- the bolt 6 is formed in an upright fashion from an unfastened member (not shown), and when the simple fastening device 1 is made to approach the bolt 6 , the bolt 6 is inserted into the bolt-insertion hole 7 of the base 2 from the side of the bolt-insertion face 2 a . As shown in FIG. 6, due to this insertion, the bolt 6 pushes up the running screw 3 . As shown in FIG. 7, due to this pushing up, the running screw 3 slides upwards along the slope portion 8 , and the running screw 3 moves upward.
- the guide projections 10 of the cover 4 are engaged with the guide grooves 11 of the running screw 3 .
- the guide face 10 a of the guide projection 10 slides in the guide groove 11 so as to achieve such an engagement.
- the guide face 10 a is inclined in the same direction as the slope portion 8 of the base 2 , so that the guide projection 10 prevents the running screw 3 from displacement, namely from slipping down or being inclined, toward the bolt-insertion hole 7 .
- the bolt 6 is smoothly inserted in the base 2 without being hooked by the running screw 3 .
- the guide grooves 11 are formed on both sides of the running screw 3 , and engaged with the guide projections 10 , respectively, so that the running screw 3 can be prevented from slipping down or being inclined.
- FIG. 8 illustrates the condition after the bolt 6 has been inserted into the base 2 , in which the spring piece 5 of the cover 4 elastically presses the top end of the running screw 3 and presses the running screw 3 downward. Due to this pressing, the running screw 3 moves downward along the slope portion 8 , and the female screw 3 a is engaged with the male screw 6 a of the bolt 6 . Due to this engagement, the bolt 6 is bought into contact with the bolt-receiving face 9 of the bolt-insertion hole 7 , and the bolt-receiving face 9 receives the reaction force of the engagement. As a result, the running screw 3 can fasten the bolt 6 without loosening.
- FIG. 9 illustrates the condition when the inserted bolt 6 has been returned slightly downward, and the female screw 3 a of the running screw 3 is engaged with the male screw 6 a of the bolt 6 .
- the guide projections 10 which constitute a guide means, and the guide grooves 11 are engaged with each other so as to prevent slipping down or inclination of the running screw 3 , and thus the bolt 6 can be smoothly inserted without being hooked by the running screw 3 . Thereby, fastening can be surely performed by one-touch insertion. Also, in this embodiment, because the spring piece 5 is integrated with the cover 4 , the number of parts can be reduced, and the entire axial length of the device can be shortened.
- FIGS. 10 and 11 illustrate Embodiment 2 of the present invention.
- a moving groove 2 b which has a slope portion 8 , is formed opposite to both sides of the bolt-insertion hole 7 .
- a pair of running screws 3 are supported by the slope portion 8 in such a way that the running screws 3 face each other.
- a pair of the running screws 3 are inserted in the base 2 in such a way that the female screws 3 a face each other.
- Guide grooves 11 are formed on the top faces of the running screws 3 and, as shown in FIG. 11, the guide projections 10 to be engaged with the guide grooves 11 are formed on the cover 4 in such a way that the number of the guide protrusions 10 equals the number of running screws 3 . Furthermore, the spring pieces 5 for pressing each of the running screws 3 downward are formed at positions of the cover 4 that correspond to the running screws 3 .
- FIGS. 12 - 16 illustrate Embodiment 3 of the present invention.
- a spring-accommodating groove 12 is formed at the end opposite to the bolt-insertion face 2 a of the base 2 .
- the spring-accommodating groove 12 is formed so as to have a predetermined length in the axial direction of the base 2 , so that a coil spring 13 can be partially inserted therein.
- Guide projections 10 which are to be engaged with the guide grooves 11 of the running screws 3 , are formed on the cover 4 .
- the guide projection 10 projects from the cover 4 in an upright fashion on the bolt-insertion face 2 a of the base 2 , in the condition that the guide projection 10 has the guide face 10 a so as to be engaged with the guide groove 11 of the running screw 3 .
- FIGS. 12 and 13 illustrate the condition before a bolt is inserted into the base 2 in this embodiment
- FIG. 14 illustrates the condition while a bolt is being inserted
- FIG. 15 illustrates the condition after a bolt has been inserted
- FIG. 16 illustrates the condition when the bolt 6 is returned slightly downward and the female screw 3 a of the running screw 3 is engaged with the male screw 6 a of the bolt 6 .
- the running screw 3 moves upward along the slope portion 8 . Because the guide projection 10 of the cover 4 is engaged with the guide groove 11 of the running screw 3 , the running screw 3 can be prevented from inclining or slipping down.
- the coil spring 13 presses the running screw 3 downward, the female screw 3 a of the running screw 3 can be engaged with the bolt 6 .
- the bolt-receiving face 9 of the bolt-insertion hole 7 receives the reaction force from this engagement, the bolt 6 can be securely fastened.
- the present invention is not limited to the above embodiments, and it can be implemented in various ways.
- the cover 4 can be omitted from the base 2 .
- the running screw 3 can be prevented from inclining or slipping down by forming the guide projection 10 at a portion of the base 2 that faces the running screw 3 . Also, when a plurality of running screws 3 are provided, more than one pair can be provided.
- a guide means can be formed easily.
