(The circumstances that led to this disclosure)
An example of the electronic device is a notebook computer (laptop PC). The notebook computer includes a first casing having a display section, a second casing having an input section, and a hinge section rotatably connecting the first casing and the second casing. Further, in the notebook computer, the first casing and the second casing rotate and are arranged at a position where the display section and the input section face each other.

In such a computer, in order to suppress the deflection of the display section that occurs when the display section and the input section are placed in positions facing each other, a frame portion of the first housing or a frame portion of the second housing is provided with a Cushioning material is attached using double-sided tape. For example, the cushioning material is attached to both ends of a frame portion of the second housing that covers the outer periphery of the input unit on the side where the input unit such as the keyboard is provided. Alternatively, the cushioning material is attached to both ends of the frame portion of the first housing that covers the outer periphery of the display section on the side where the display section such as the liquid crystal panel is provided.

In recent years, consideration has been given to improving the aesthetics of computers by narrowing the widths of the frame portions of the first and second casings. When the widths of the frame portions of the first and second housings are narrowed, the installation area of the cushioning material becomes smaller. For this reason, when using a method of fixing the cushioning material with double-sided tape or the like, the cushioning material may fall off from the housing. For example, if an external force is applied to the cushioning material by a user's finger or the like touching the cushioning material, the cushioning material may fall off from the casing. In particular, in a tablet state where the display section and the input section are exposed to the outside, the user's fingers and the like are likely to touch the cushioning material, and the cushioning material is likely to fall off.

Therefore, the present inventors have developed a planar main body having a longitudinal direction, a plurality of first locking portions provided at both ends in the longitudinal direction of the main body, and at least one of a first main surface portion and a second main surface portion of the main body. A cushioning material including one or more second locking portions protruding to either side was discovered, and the following invention was achieved.

The first housing 2 and the second housing 3 are connected via a hinge portion 7. The hinge portion 7 rotatably connects the first housing 2 and the second housing 3. The hinge portion 7 allows the first casing 2 and/or the second casing 3 to rotate, thereby placing the electronic device 1 in an open state and a closed state. Note that the "open state" means a state in which the first casing 2 and the second casing 3 are separated and the display section 4 and input sections 5 and 6 are exposed. The "closed state" means that the first housing 2 and the second housing 3 are arranged facing each other, the display section 4 and the input sections 5 and 6 are facing each other, and the display section 4 and the input section 5, 6 means not exposed.

[effect]
According to the cushioning material 10 of the first embodiment, the following effects can be achieved.

The cushioning material 10 includes a main body 11, a plurality of first locking parts 20A, 20B, and a plurality of second locking parts 30A, 30B. The main body 11 is formed of a plate-shaped elastic body having a longitudinal direction (Y direction), a lateral direction (Z direction), and a thickness direction (X direction). Moreover, the main body 11 has a first main surface part PS1 and a second main surface part PS2 provided on the opposite side to the first main surface part PS1. Moreover, the main body 11 has a first side end QS1 and a second side end QS2 provided at both ends in the longitudinal direction (Y direction) of the first main surface part PS1 and the second main surface part PS2. Moreover, the main body 11 has a first end RS1 and a second end RS2 provided at both ends in the lateral direction (Z direction) of the first main surface part PS1 and the second main surface part PS2. The plurality of first locking portions 20A and 20B are provided at the first side end QS1 and the second side end QS2 of the main body 11, respectively. The plurality of second locking portions 30A and 30B are provided to protrude toward the first main surface portion PS1 side and the second main surface portion PS2 side of the main body 11, respectively.

With such a configuration, it is possible to suppress the cushioning material 10 from falling off from the object to which it is attached, such as the electronic device 1. Further, the plurality of first locking parts 20A, 20B and the plurality of second locking parts 30A, 30B can lock the cushioning material 10 in both the longitudinal direction and the width direction of the main body 11. Thereby, for example, even if an external force is applied to the cushioning material 10, it is possible to suppress the cushioning material 10 from falling off.

The plurality of second locking parts 30A and 30B each have a first protrusion and a second protrusion. The first protrusion extends from the second end RS2 in a direction away from the main body 11 in the lateral direction (Z direction) of the main body 11, and extends from the first main surface PS1 in the thickness direction (X direction) of the main body 11. It is bent in a direction away from the main body 11. The second protrusion extends from the second end RS2 in a direction away from the main body 11 in the lateral direction (Z direction) of the main body 11, and extends away from the second main surface PS2 in the thickness direction (X direction) of the main body 11. It is bent in a direction away from the main body 11.

With such a configuration, falling off of the cushioning material 10 can be further suppressed. For example, even if an external force is applied to the cushioning material 10 from the thickness direction (X direction) of the cushioning material 10, the first protrusion and the second protrusion can prevent the cushioning material 10 from falling off.

The plurality of second locking portions 30A, 30B have a plurality of inclined surfaces 31A, 31B on the side opposite to the side from which the plurality of second locking portions 30A, 30B protrude.

With such a configuration, it is possible to more easily attach the cushioning material 10. For example, when attaching the cushioning material 10 to the groove 8 provided in the electronic device 1, it becomes easier to insert the plurality of second locking parts 30A, 30B into the plurality of attachment holes 9C, 9D provided in the groove 8. .

In the main body 11, a plurality of recesses 12A, 12B are provided at positions where the plurality of second locking portions 30A, 30B are provided, and on the main surface portion on the opposite side to the side from which the plurality of second locking portions 30A, 30B protrude. is provided.

With such a configuration, it is possible to more easily attach the cushioning material 10. When inserting the plurality of second locking parts 30A, 30B into the plurality of attachment holes 9C, 9D, it is possible to secure a space in which the plurality of second locking parts 30A, 30B are elastically deformed. Thereby, for example, when attaching the cushioning material 10 to the groove 8 provided in the electronic device 1, the plurality of second locking parts 30A, 30B are inserted into the plurality of attachment holes 9C, 9D provided in the groove 8. It becomes easier.

The depth t2 of the plurality of recesses 12A, 12B is 0.8 times or more and 1.2 times or less the protrusion amount t1 of the plurality of second locking parts 30A, 30B in the thickness direction (X direction) of the main body 11.

With such a configuration, it is possible to more easily attach the cushioning material 10.

The cushioning material 10 includes a plurality of ribs 13 provided on the first principal surface portion PS1 and the second principal surface portion PS2 of the main body 11 and protruding in the thickness direction (X direction) of the main body 11.

With such a configuration, the main body 11 can be supported from the sides by the plurality of ribs 13, so that falling off of the cushioning material 10 can be further suppressed.

The plurality of ribs 13 have a semi-cylindrical shape with a longitudinal direction in the lateral direction (Z direction) of the main body 11.

With such a configuration, the main body 11 can be supported from the side while maintaining ease of attaching the cushioning material 10.
