Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a seat for general furniture or a vehicle, and particularly relates to an upwardly rotating seat.

(Prior Art) Some motorcycle seats are fixed so that they do not move, while others have a pivot-mounted structure that allows them to rotate upwards about an axis.

In other words, by rotating the seat upwards and placing small items underneath, you can easily transport items.
Also, when it rains, you can rotate the seat upwards to avoid getting wet. Also, some devices have a structure in which the oil filler port is exposed when the seat is rotated upward.

(Problems to be Solved by the Invention) However, as shown in FIG. 1, the conventional seat shaft mounting structure is a shaft mounting using screws.

That is, A is a seat part, B and B' are support arms, C is a mounting part, D is a threaded rod, and E is a nut.
The support arm B hanging down from the seat part A on the lower surface of the
B' comes into contact with the mounting part C protruding from the vehicle body,
A threaded rod D was inserted through it and tightened with a nut E to secure it.

In this structure, align the screw holes of the support arms B and B' of the seat part A with the screw holes of the mounting part C, insert the threaded rod D while holding it in place with your hands, and then rotate the nut E. This was troublesome because it required a manual tightening operation and the use of a tool such as a spanner.

Therefore, we have developed a seat that can be easily and securely installed without the need for tools.

(Means for Solving the Problems) Therefore, the present invention provides a seat for general furniture or a vehicle, which satisfies the following requirements (1) to (3).

(1) The horizontal portion 2, the bent portions 3 and 4, and a pair of support arms 5 and 6 provided on the lower surface of the horizontal portion 2
and a mounting shaft 7 provided at the lower end portions of the pair of support arms 5, 6 are integrally formed of synthetic resin to constitute the frame 1.

(2) On the vehicle body 11 side, insert a pull-out prevention piece 15 having a fitting hole 12 with a notch 13 formed on either the front or rear side and an engagement hole 16 on the upper edge through the bent portion 14. A mounting part 10 made of synthetic resin is provided so as to be bendable.

(3) Insert the mounting shaft 7 of the frame 1 into the fitting hole 1.
2, the notch 13 is elastically enlarged and fitted, and the removal prevention piece 15 is bent downward to engage the engagement hole 16 with the outer end 17 of the mounting shaft 7.

(Example) An example of the present invention will be described with reference to the drawings.
is a horizontal part of the seat, and 3 and 4 are bent parts. In some cases, the upper surfaces of the horizontal portion 2 and the bent portions 3 and 4 are simply covered with a thin skin and used directly as a seat.

A pair of left and right support arms 5 and 6 are provided on the lower surface of the horizontal portion 2 and are vertically suspended. A mounting shaft 7 whose axis is parallel to the horizontal portion 2 is attached to the lower ends of the support arms 5 and 6.

A distance T is provided between the upper surface 8 of the mounting shaft 7 and the lower surface 9 of the horizontal portion 2. The axial direction of the mounting shaft 7 is the left-right direction.

Reference numeral 10 denotes a mounting part that is attached to the vehicle body 11 side, and when viewed from the front or rear side, it has a U-shape as shown in FIG. Fitting holes 12, 12 into which the mounting shaft 7 fits are provided. Fitting hole 12
has a notch 13 on the back side or front side (front and rear sides), and communicates with the outside via the notch 13, and when the mounting shaft 7 is forcibly fitted through the notch 13, It is configured so that the notch 13 can be enlarged and fitted.

Furthermore, a pull-out prevention piece 15 is provided in a row at the upper end of the mounting portion 10 so as to be bendable. An engagement hole 16 is connected to the removal prevention piece 15 via the bending part 14, and when the removal prevention piece 15 is bent and the engagement hole 16 is engaged with the outer end 17 of the mounting shaft 7, the installation shaft 7 will not come off from the notch 13.

FIG. 6 shows a mounting shaft 7 with the notch 13 deformed.
It is a state diagram in which the two are fitted together.

Horizontal portion 2 and bent portions 3 and 4, and the horizontal portion 2
A frame 1 is constituted by a pair of support arms 5 and 6 provided on the lower surface portion and a mounting shaft 7 provided at the lower end portion of the pair of support arms 5 and 6, and the frame 1 is made of synthetic resin and is integrally formed. is formed. Further, the U-shaped mounting portion 10 is also made of synthetic resin.

(Operations/Effects) Of the above configurations, the present invention forms the frame 1 by integrally forming the horizontal portion 2, the bending portions 3, 4, the supporting arms 5, 6, and the mounting shaft 7 from synthetic resin. This is one of its characteristics.

In the conventional frame, as shown in Fig. 1, the frame consisting of the seat part A, support arms B, B', and threaded rod D were all formed separately, so three members were formed separately. It required a lot of effort. Another drawback is that the two support arms B and B' must be connected to the lower surface of the seat A by some means.

In contrast, the present invention includes a horizontal portion 2, bent portions 3, 4, a pair of support arms 5, 6 provided on the lower surface of the horizontal portion 2, and lower end portions of the pair of support arms 5, 6. Since the mounting shaft 7 provided on the frame 1 is integrally formed of synthetic resin and constitutes the frame 1, the manufacturing effort is significantly simplified.

Further, the present invention provides an attachment portion 10 attached to the vehicle body 11 side.
On the other hand, the second feature is that a fitting hole 12 with a notch 13 is formed, and the mounting shaft 7 is forcibly fitted into and fastened.

That is, since the mounting part 10 mounted on the vehicle body 11 side is also made of synthetic resin, the mounting shaft 7 is placed in the notch 13 of the fitting hole 12, and the mounting shaft 7 is
When pressed forcibly, the notch 13 is elastically deformed as shown in FIG. 6, and can be fixed. therefore,
Since the shaft can be attached simply by abutting and pressing, the fixing operation is much easier than in the known example.

Further, the present invention provides a detachment prevention piece 15 on the mounting portion 10.
The third feature is that they are connected in a bendable manner via a bending portion 14, and the pull-out prevention piece 15 is formed with an engagement hole 16 that engages with the outer end 17 portion of the mounting shaft 7. Therefore, in the present application, after fitting the mounting shaft 7 into the fitting hole 12, the removal prevention piece 15 is bent and the fitting hole 12 is bent.
If it is fitted onto the outer end 17 of the mounting shaft 7, it will be prevented from coming off and the operation will be extremely easy.
