Fastening member, and obstacle detecting device employing fastening member
View Patent ↗A fastening device is configured to be used for fastening an object to a target device. The fastening device includes a holder part configured to hold the object, a fastening part configured to be bonded to the target device, a contact part allowing the fastening part to be located between the contact part and the holder part, and a connecting part for connecting the contact part with the fastening part while allowing the protruding length to be variable. The contact part protrudes toward the target device more than the fastening part by a protruding length, the contact part contacting the target device before the fastening part contacts the target device when being fastened to the target device. This fastening device improves workability.
1. A fastening device used for fastening an object to a target device having a target surface, the fastening device comprising:
a fastening part that has a plate shape having a flat upper surface and a flat lower surface, the lower surface configured to be bonded to the target surface of the target device;
a holder part configured to hold the object, the holder part protruding from the upper surface of the fastening part;
a contact part configured to contact the target device, the contact part protruding toward the target surface of the target device by a predetermined length such that a tip of the contact part contacts the target surface of the target device when the object is fastened to the target device; and
a connecting part connecting the contact part with the fastening part, the connecting part protruding from an end of the fastening part in a first lateral extending direction of the fastening part, and the contact part protruding from an end of the connecting part,
wherein the connecting part and the contact part are elastically deformable such that the tip of the contact part maintains contact with the target surface of the target device when the object is fastened to the target device.
2. The fastening device of claim 1 , wherein
the contact part protrudes more than the lower surface of the fastening part.
3. The fastening device of claim 1 , wherein
the connecting part is connected to the lower surface of the fastening part.
4. The fastening device of claim 1 , wherein
the fastening part, the connecting part, and the contact part define a unitary component part, and
the connecting part is thinner than the fastening part and the connecting part.
5. The fastening device of claim 1 , wherein
the contact part is at least three contact parts, and
the at least three contact parts are disposed along the end of the connecting part so as to surround the holder part and project toward the target device.
6. The fastening device of claim 1 , further comprising:
an attachment direction indicator for indicating a direction in which the object is fixed with respect to the holder part.
7. The fastening device of claim 1 , wherein
the holder part has a restricting part configured to permit the object to be fastened only in a predetermined direction.
8. The fastening device of claim 1 , wherein
the fastening part has a groove on the upper surface of the fastening part between the holder and the edge of the fastening part, and
the groove extends in a second lateral direction orthogonal to the first lateral direction.
9. An obstacle detector comprising:
the fastening device of claim 1 ; and
a sensor as the object for detecting an obstacle.
10. The obstacle detector of claim 9 , wherein
the fastening device is fastened to an exterior plate as the target device of a vehicle.
11. The fastening device of claim 1 , wherein
a protruding direction of the holder part from the fastening part is opposite to a protruding direction of the contact part from the end of the connecting part.
12. The fastening device of claim 1 , wherein
the contact part protrudes from the end of the connecting part in a direction orthogonal to
the first lateral extending direction of the fastening part, and
the end of the connecting part is a side edge end of the connecting part.
13. The fastening device of claim 1 , wherein
the connecting part and the contact part are elastically deformable by a force to be applied to the holder part along a direction opposite to a protruding direction of the holder part.
14. The fastening device of claim 1 , further comprising one of a double-sided adhesive tape or an adhesive provided on the lower surface of the fastening part,
wherein the lower surface of the fastening part is to be bonded to the target surface of the target device via the one of the double-sided adhesive tape or the adhesive, and
the predetermined length of the contact part protruding toward the target surface of the target device with respect to the lower surface of the fastening part is greater than a thickness of the one of the double-sided adhesive tape or the adhesive.
