Abstract

A part fixture which is locked on a locking portion of a vehicle body and which is inserted into a mounting hole on a mount portion provided on a vehicle body to be fixed in place therein to thereby mount the vehicle part on the mount portion, includes an accommodating portion, a locking piece, a pair of flange portions, and a pair of elastic engaging pieces. The elastic engaging pieces each have an engaging claw and an operation knob. When the pair of elastic engaging pieces are deflected inwards of the accommodating portion, the pair of elastic engaging pieces are brought into abutment with the side wall portions or the locking portion of the vehicle part which is accommodated in the accommodating portion so that any further deflection thereof is restricted.

First claim

The invention claimed is:

1. A part fixture which is locked on a locking portion of a vehicle body and which is inserted into a mounting hole on a mount portion provided on a vehicle body to be fixed in place therein to thereby mount the vehicle part on the mount portion, comprising:
an accommodating portion which is formed into the shape of a frame which has an opening portion through which the locking portion can be inserted and has wall portions which are disposed so as to face each other and at least a pair of side wall portions which are disposed so as to intersect with a direction in which the wall portions are disposed to face each other, which accommodates the locking portion of the vehicle part and which is inserted into the mounting hole;
a locking piece which is provided on the wall portion of the accommodating portion so as to extend therefrom and which locks on the locking portion which is accommodated in the accommodating portion;
a pair of flange portions which, are provided on the wall portion of the accommodating portion so as to extend therefrom and which are brought into engagement with a circumferential edge on a front side of the mounting hole; and
a pair of elastic engaging pieces which are provided individually so as to extend outwards from the pair of side wall portions of the accommodating portion in such a way as to be deflected,
wherein the elastic engaging pieces each have:
an engaging claw which is brought into engagement with a circumferential edge on a rear side of the mounting hole; and
an operation knob which is disposed on a front side of the mounting hole with the engaging claw left in engagement with the circumferential edge on the rear side of the mounting hole and which is configured to deflect the elastic engaging piece inwards of the accommodating portion to thereby release an engagement of the engaging claw with the circumferential edge on the rear side of the mounting hole, and

wherein when the pair of elastic engaging pieces are deflected inwards of the accommodating portion by operating the operation knob, the pair of elastic engaging pieces are brought into abutment with the side wall portions or the locking portion of the vehicle part which is accommodated in the accommodating portion so that any further deflection thereof is restricted in a state where the engagement of the engaging claw with the circumferential edge on the rear side of the mounting hole is released.

2. The part fixture according to claim 1 , wherein the operation knob is disposed apart from a circumferential edge on the front side of the mounting hole with a predetermined space defined therebetween in such a state that the engaging claws of the elastic engaging pieces are in engagement with the circumferential edge on the rear side of the mounting hole.

3. The part fixture according to claim 1 , wherein gripping surfaces of the operation knob which are used when the operation knobs are operated are formed into inclined surfaces which are inclined diametrically further outwards as the gripping surfaces extend further away from the engaging claws.

4. The part fixture according to claim 1 , further comprising a locking releasing mechanism configured to release the engagement of the locking piece with the locking portion,
wherein the locking releasing mechanism comprises a groove portion which is formed in the wall portion of the accommodating portion on which the locking piece is provided so that a distal end portion of a tool can be locked therein.

5. The part fixture according to claim 1 , wherein the pair of elastic engaging pieces are provided on the side wall portions of the accommodating portion so as to individually extend obliquely outwards from distal end sides of the side wall portions in relation to an inserting direction in which the part fixture is inserted into the mounting hole towards proximal end sides of the side wall portions in relation to the same inserting direction.

6. The part fixture according to claim 1 ,
wherein ribs are formed on both sides of the elastic engaging piece of each of the side wall portions of the accommodating portion, ribs each having a tapered portion which becomes narrower towards a tip thereof, and
wherein with the accommodating portion inserted into the mounting hole and the engaging claws of the pair of elastic engaging pieces left in engagement with the circumferential edge on the rear side of the mounting hole, when an eccentric load is exerted on the accommodating portion so as to deflect inwards one of the pair of elastic engaging pieces, the rib on the one of the pair of elastic engaging pieces is brought into abutment with an inner circumference of the mounting hole before the other of the pair of elastic engaging pieces is released from the engagement with the circumferential edge on the rear side of the mounting hole.

7. A part fixture which is locked on a locking portion of a vehicle body and which is inserted into a mounting hole on a mount portion provided on a vehicle body to be fixed in place therein to thereby mount the vehicle part on the mount portion, comprising:
an accommodating portion which is formed into the shape of a frame which has an opening portion through which the locking portion can be inserted and has wall portions which are disposed so as to face each other and at least a pair of side wall portions which are disposed so as to intersect with a direction in which the wall portions are disposed to face each other, which accommodates the locking portion of the vehicle part and which is inserted into the mounting hole;
a locking piece which is provided on the wall portion of the accommodating portion so as to extend therefrom and which locks on the locking portion which is accommodated in the accommodating portion; and
a pair of elastic engaging pieces which are provided individually on the pair of side wall of the accommodating portion so as to extend therefrom in such a way as to be deflected,
wherein the elastic engaging pieces each have:
an engaging claw which is brought into engagement with a circumferential edge on a rear side of the mounting hole; and
an operation knob which is disposed on a front side of the mounting hole with the engaging claw left in engagement with the circumferential edge on the rear side of the mounting hole and which is configured to deflect the elastic engaging piece inwards of the accommodating portion to thereby release an engagement of the engaging claw with the circumferential edge on the rear side of the mounting hole,

wherein the side wall portions of the accommodating portion have a pair of outer frame-shaped portions on which the elastic engaging pieces are provided and a pair of inner wall portions which are disposed inwards of the pair of outer frame-shaped portions with a predetermined space provided therebetween, and
wherein when the pair of elastic engaging pieces are deflected inwards of the accommodating portion by the operation knob, the pair of elastic engaging pieces are brought into abutment with the inner wall portions so that any further deflection thereof is restricted in a state where the engagement of the engaging claw with the circumferential edge on the rear, side of the mounting hole is released.

8. The part fixture according to claim 7 , wherein the operation knob is disposed apart from a circumferential edge on the front side of the mounting hole with a predetermined space defined therebetween in such a state that the engaging claws of the elastic engaging pieces are in engagement with the circumferential edge on the rear side of the mounting hole.

9. The part fixture according to claim 7 , wherein gripping surfaces of the operation knob which are used when the operation knobs are ope
