Description

[Detailed Description of the Invention] The present invention relates to a sliding roof used in a keyboard instrument such as an electronic organ.

Conventionally, this kind of rolling roof is constructed by connecting multiple roof members in the form of split plates with screwed hinges, but it takes time and effort to screw the hinges together, and requires complicated hinges and screws. Therefore, there was an inconvenience that the cost was high.

The purpose of the present invention is to eliminate such inconveniences and to provide a sliding type roof in which the hinge does not shift position on the roof member even if force is applied to the roof member. In a type in which roof members 1 and 1 are connected to each other by a hinge 2, the hinge 2 is integrally made of an elastic material, and its bent portion 3 is formed thin, and at least one piece is provided on both sides of the bent portion 3. A pair of parallel hook-shaped pieces 4, 4 and a pressing piece 5 interposed between the hook-shaped pieces 4, 4 are each erected,
The locking pieces 6, 6 provided on the mutually adjacent roof members 1, 1 are fitted into the gap formed by the pair of hook-shaped pieces 4, 4 and the pressure-welding piece 5, and the hook-shaped pieces 4, 4 are fitted. It gets stuck.

In FIGS. 1 to 3, two sets of the pair of hook-shaped pieces 4, 4 of the hinge 2 and the pressing piece 5 located therebetween are provided on each side of the bent portion 3. The hinge 2 is made of an elastic material such as polypropylene or nylon, and its width is slightly longer than the distance between the locking pieces 6, 6 so that the pressure contact piece 5 is elastically pressed against the locking pieces 6, 6. Moreover, a cavity was provided inside it.

In the drawings, the bent portion 3 of the hinge 2 is made thin by forming a groove on one main surface, but it may be made thin by forming grooves on both main surfaces. Furthermore, in the drawings, the locking pieces 6, 6 are formed integrally with the reinforcing member 7 that is locked to the roof member 1, but they may also be formed directly on the roof member 1 made of aluminum, synthetic resin, etc. It can also be formed in the reinforcing member 7 formed in.

To fix the hinge 2 to the roof member 1, fit the locking pieces 6, 6 into the gaps between the hook-shaped pieces 4, 4 of the hinge 2 and the press-fitting piece 5, push down the hinge 2, and press down the hook-shaped pieces 4, 4. The protrusions 4a, 4a and the locking pieces 6, 6 are engaged. In this state, the pressure contact piece 5 comes into pressure contact with the inner wall of the locking pieces 6, 6 by elastic force, and a frictional force is generated between the two.
Even if force is applied to the reinforcing member 7 in the longitudinal direction, its position is less likely to shift.

FIG. 4 shows an electronic organ equipped with a rolled-up roof consisting of a plurality of roof members 1 connected in this manner.

Side plates fixed to both sides of the plurality of roof members 1 are fitted into guides provided on the side plates 9, 9 of the electronic organ main body 8, and the rolled-up roof is guided by the guides and slides back and forth.

In this way, according to the present invention, the hinge is integrally made of an elastic material and its bent portion is formed thin, and at least one pair of hook-shaped pieces and pressure-welding pieces are arranged in parallel on both sides of the bent portion. Since the hinge is fixed to a locking piece provided on the roof member, it is easy to attach the hinge to the roof member, and the material cost is low, and the process of attaching the folding roof to an electronic organ, etc. This has the effect that even if a force is applied to the reinforcing member in the longitudinal direction, its position will not shift.

[Scope of utility model registration request] In a type in which a plurality of split plate-like roof members 1, 1 are connected to each other by a hinge 2, the hinge 2 is made of an elastic material and the bent portion 3 is formed thin, and both sides of the bent portion 3 are formed. At least one pair of parallel hook-shaped pieces 4, 4 and a pressure-welding piece 5 interposed between the hook-shaped pieces 4, 4 are each erected, and the pair of hook-shaped pieces 4, 4 and the pressure-welding piece 5 The sliding type roof is formed by fitting the locking pieces 6, 6 provided on the roof members 1, 1 adjacent to each other into the gap formed by the above and locking the locking pieces 6, 6 to the hook-shaped pieces 4, 4.
