Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a mounting device for an exterior cover that conceals a seat receiving bracket of a chair.

The present invention is intended to provide a device for attaching an exterior cover of a seat receiving metal fitting part, which is easy to assemble, in which the above-mentioned conventional problems are improved and design aesthetics and product value are improved.

MEANS FOR SOLVING PROBLEMS The present invention has a feature in that an outer cover of a seat receiving bracket of a chair can be easily attached, and a frame-shaped support member 2 fixed on a pedestal 1, A movable seat receiving member 3 whose one end is mounted on a supporting member 2 by a support shaft 4 and which is constantly pressed upward by the elastic force of a spring installed inside, a frame portion 5a of a mold, and a continuous portion thereof. In the above state, the upper cover 5 is composed of a semi-arcuate frame 5b and a joint portion 5c that are hung downward, a dish-shaped frame portion 6a, and a semi-circular joint portion 6b that is protruded downward at one end. And the lower cover 6 and the upper cover 5
The frame-shaped portion 5a is fitted to the outside of the support member 2, and the frame-shaped portion 5a
A plurality of locking pins 7 projecting inside are engaged with locking holes 8 bored in the side surface of the support member 2 from the outside and at the same time formed on the end face in the longitudinal direction of the frame-shaped portion 6a of the lower cover 6. The fitting groove 9 is engaged with the lower end portion of the upper cover 5 including the semi-circular frame 5b, and the outer projecting end portion of the support shaft 4 of the movable seat receiving member 3 is inserted into the drop groove 10 formed in the lower cover 6. At the same time as engaging, the locking claws 11 projecting from the bottom wall 6c of the lower cover 6 are fixed to the locking edges 12 protruding inside the bottom of the support member 2, and the pedestal cover 13 is further connected to the joint 5c. , 6b from the outside to join the joints 5c,
The gist is a structure in which an annular claw 14 projecting outward from 6b is engaged with an annular rib 15 projecting inward into a pedestal cover 13.

EXAMPLE An example of the present invention will be described below in detail with reference to the drawings. 1 is a pedestal, 2 is a support member fixed on the pedestal 1, and 3 is a supporting column.
Is mounted on one end of the support member 1 with a support shaft 4 and is constantly pressed upward by the elastic force of a spring installed inside. The movable seat receiving member 5 is integrated downward with the frame 5a of the mold. An upper cover consisting of a semi-circular frame 5b and a joint portion 5c which are vertically installed on the support member 2. The upper cover 5 is fitted to the outside of the support member 2 and two side holes of the support member 2 are formed. The upper cover 5 is fixed to the support member 2 by engaging the locking pin 7 protruding from the outside in the locking hole 8 from the outside. Reference numeral 6 denotes a lower cover which is composed of a dish-shaped frame portion 6a and a semi-arcuate joint portion 6b which is continuously provided at one end of the frame portion 6a of the lower cover 6.
The engaging groove 9 formed on the upper end surface of the upper cover 5 is fitted to the lower end portion of the upper cover 5, and the outer protruding portion of the support shaft 4 is engaged with the drop groove 10 provided inside the frame-shaped portion 6a. An engaging claw 11 protruding from the bottom wall 6c of the shaped portion 6a is attached to an engaging edge 12 protruding inside the bottom of the support member 2. Reference numeral 13 denotes a pedestal cover. The cover 13 is fitted to the joint portion 5c of the upper cover 5 and the joint portion 6b of the lower cover 6, and is projected on the outer side of both joint portions 5c and 6b to form an annular claw 14.
An annular rib 15 projecting inward of the pedestal cover 13 is attached to this.

The operation and effect of the invention According to the present invention, the upper cover 5 is fitted to the support member 2, the locking pin 7 is engaged with the locking hole 8, and then the engaging groove 9 of the lower cover 6 is inserted into the upper cover 5. When it is engaged in a state in which it is slightly strongly pressed against, the locking claw 11 automatically engages with the locking edge 12 of the support member 2 by utilizing its own elasticity, and then fits on the preliminarily pedestal 1. When the combined pedestal cover 13 is strongly pressed upward, the pedestal cover 13 is
Fits into the joints 5c and 6b of the covers 5 and 6, and the annular rib 15 engages with the annular claw 14 to complete the assembly.

In this case, the upper cover 5 is fitted to the support member 2 and the lower cover 6 is strongly pressed from the lower side as described above.
When the lower end portion of the upper cover 5 is engaged with the engaging groove 9 at the same time, the locking claw 11 automatically engages with the locking edge 12 of the support member 2, and then the pedestal cover 13 is joined. Assembly is completed by fitting to 5c and 6b. Easy and quick assembly is possible, workability is further improved, and the upper cover 5
Is fixed to the support member 2 by a lock pin 7, and the lower cover 6 is joined and integrated with the upper cover 5, and the locking claw 11 is engaged with the locking edge 12 of the support member 2. , A very tightly assembled state can be obtained, and the seat receiving metal fittings are completely hidden by the upper cover 5 and the lower cover 6, so that a high-class chair which is elegant in design and which can remarkably increase the commercial value is obtained. And so on.
