JP5706124B2 - Lid device and storage device - Google Patents

Description

  The present invention relates to a lid device used for, for example, an automobile console box, and a storage device including the lid device.

  Conventionally, for example, a storage device such as a console box provided with a lid device is used in a passenger compartment of an automobile.

  As such a console box lid device, a so-called shutter-type lid device is known in which a bendable plate-like lid body is moved along a guide rail. As such a lid device, for example, the surface side of a large number of piece-like hard resin portions arranged side by side is covered with a soft resin portion, and the hard resin portions are connected to each other with this soft resin portion. A configuration in which a thin bendable portion is formed between hard resin portions is known. The lid device is formed by so-called two-color molding, and the material of the soft resin portion is introduced into a mold in which the hard resin portion formed in advance (primary formation) is arranged, and integrated with the hard resin portion. A plate-like soft resin portion joined to the substrate is formed (secondarily formed) (see, for example, Patent Document 1).

  However, in this configuration, the soft resin portion is continuously formed in the width direction of the lid device, that is, uniformly formed over the entire length in the longitudinal direction on the surface side of the hard resin portion. Therefore, at the time of so-called secondary shrinkage at the time of shrinkage when the material of the soft resin portion is cured, the entire lid device is curved so that both ends in the width direction are warped upward against the rigidity of the hard resin portion. There is a risk. Here, for example, a configuration in which a large rib is formed on the back surface side of the hard resin portion to increase the rigidity of the hard resin portion is conceivable, but in this configuration, a large amount of resin material is required, and mass and manufacturing costs are increased. As the number of the ribs increases, the rib on the back surface protrudes toward the storage portion such as the console box, and the space that can be stored is reduced.
