FIG. 7B is a partial schematic view of the display device 601 attached to the plate 602 as viewed from the rear. FIG. 7C is a cross-sectional view illustrating a state where the display device 601 is attached to the plate 602.
As shown in FIG. 7A, the fixing member 701 is inserted from the back side of the display device 601 inserted into the plate 602 in FIG. The fixing member 701 is integrally formed of a resin having both rigidity and elasticity, such as polycarbonate. A pressing member 701a for sandwiching the plate 602 with the panel 601b of the display device 601 is formed on the front side of the fixing member 701. The pressing member 701a is connected to the grip portion 701c through an elastic member 701b that is elastically deformed in a pantograph shape.

  As shown in FIG. 7B, the holding portion 701c provided on the fixing member 701 has a protrusion 701e that fits with rail grooves 601e and 601f provided on the top and bottom surfaces of the display device 601 near the side surface 601c. , 701f. As shown in FIGS. 7B and 7C, at the center of the gripping portion 701c, there is a pawl 701g (claw) that meshes with a rack 601d provided on the side surface 601c of the housing 601a at the center thereof, and an elastically deforming engagement.

FIG. 1 is an external perspective view of a display device 101 and a fixing member 102 according to an embodiment of the present invention.
FIG. 2 is an external perspective view of the fixing member 102.
FIG. 3A is a top view of the fixing member 102. FIG. 3B is a front view of the fixing member 102. FIG. 3C is a side view of the fixing member 102. FIG. 3D is a rear view of the fixing member 102.

  The display device 101 (electronic device main body) shown in FIG. 1 includes rail grooves 101e, 101f (see FIG. 5B), 101g provided on the top and bottom surfaces of the display device 101 near the side surfaces, and the display device 101. This is the same in that a sawtooth rack 101d that meshes with the fixing member 102 is formed on the side surface 101c of the casing 101a. The fixing member 102 corresponding to the rail grooves 101e and 101f is also provided with protrusions 102e and 102f that fit into the rail grooves 101e and 101f of the display device 101, as in the fixing member 701 according to the prior art (see FIG. 7). It has been.

The fixing member 102 shown in FIGS. 1, 2 and 3 is integrally formed of a resin having both rigidity and elasticity, such as polycarbonate, like the fixing member 701 according to the prior art. A pressing member 102 a for sandwiching a plate or the like with the panel 101 b of the display device 101 is formed on the front side of the fixing member 102. The pressing member 102a is connected to the U-shaped main body portion 102c via a substantially elliptical elastic member 102b that is elastically deformed. The elastic member 102b is slightly different from the conventional one shown in FIG. 7, but has the same function of elastic deformation.
The material of the fixing member 102 is not limited to polycarbonate. As long as the material has both rigidity and elasticity, a resin other than polycarbonate may be used, and not only the resin but also a metal thin plate such as stainless steel or chrome molybdenum steel may be formed by sheet metal processing.

A major difference between the fixing member 102 shown in FIGS. 1, 2 and 3 and the fixing member 701 according to the prior art described in FIG. 7 is the shape of the elastically deformable locking member 102h having pawls 102g. .
A beam 102d is provided behind the U-shaped main body 102c, and a locking member 102h is formed at the center of the beam 102d. The locking member 102h has a lever 102i facing the beam 102d. As can be seen from FIGS. 2, 3C, and 4, the lever 102i is inclined with respect to a plane parallel to the main body 102c and the locking member 102h.
A pawl 102g that meshes with a rack 101d provided on the side surface 101c of the housing 101a is provided at the tip of the locking member 102h.

  As will be described later with reference to FIG. 5C and FIG. 5D, the teeth of the rack 101d are formed so that one side is inclined to the front side of the housing 101a and the other side is vertical, like the rack 601d of FIG. The pawl 102g provided at the tip of the locking member 102h meshes with the teeth of the rack 101d. When the fixing member 102 is inserted from the rear side of the casing 101a and the pressing member 102a at the tip is pressed against the back side of the wall, the repulsive force of the elastic member 102b cooperates with the panel 101b to sandwich the wall. The fixing member 102 does not come off the display device 101 when the pawl 102g of the locking member 102h and the teeth of the rack 101d are engaged with each other. That is, the locking member 102h and the rack 101d constitute a ratchet.

FIG. 4 is a cross-sectional view for explaining the operation of the fixing member 102.
FIG. 5A is a schematic view of the state in which the display device 101 is attached to the plate 602 as seen from the lateral direction. FIG. 5B is a partial schematic view of the display device 101 attached to the plate 602 as viewed from the rear. FIG. 5C is a cross-sectional view illustrating a state where the display device 101 is detached from the plate 602. FIG. 5D is a cross-sectional view illustrating a state in which the fixing member 102 is deformed when the display device 101 is detached from the plate 602.

As can be seen at a glance, FIGS. 5A and 5B are substantially the same as FIGS. 7A and 7B in the prior art. That is, the fixing member 102 according to the embodiment of the present invention is the same as the fixing member 701 according to the related art described with reference to FIG. 7 in the function of fixing the display device 101.
The advantage of the fixing member 102 according to the embodiment of the present invention over the fixing member 701 according to the prior art is a function when the display device 101 is detached from the plate.
As shown in FIGS. 4, 5C, and 5D, the locking member 102h rotates in a seesaw manner around the beam 102d by pushing the inclined lever 102i according to the lever principle. At this time, torsional elastic deformation occurs in the beam 102d. Then, the locking member 102h that meshes with the rack 101d provided on the side surface 101c of the housing 101a of the display device 101 can be released.

  In the fixing member 701 according to the related art described in FIG. 7, when the display device 601 is removed, the direction of the force for removing the locking member 701h formed on the pressing member 701a from the rack 601d is the locking member 701h. Was peeled off from the display device 601. Therefore, it is difficult to apply a force for removing the locking member 701h from the rack 601d. Compared to this, when the fixing member 102 according to the embodiment of the present invention removes the display device 101, the direction of the force for removing the locking member 102h formed on the pressing member 102a is different from that of the lever 102i. It is a direction to press against 101. To remove the locking member 102h from the rack 101d, it is only necessary to press the lever 102i against the housing 101a, and the locking member 102h can be removed with a slight force according to the lever principle.

In the embodiment of the present invention, the fixing member 102 for fixing the display device 101 to an arbitrary plate or wall is disclosed.
A rack 101d provided on the side surface 101c of the casing 101a of the display device 101 and a pawl 102g that engages with the rack 101d provided at the tip of the locking member 102h of the fixing member 102 constitute a ratchet. The locking member 102h rotates around the beam 102d that is elastically deformed by pushing the lever 102i. The fixing member 102 can release the ratchet only by lightly pushing the lever 102i toward the housing 101a.

In the embodiment of the present invention, a form in which the display device 101 and the fixing member 102 are fitted to the housing side surface 101c by the rail grooves 101e, 101f, 101g and the protrusions 102e, 102f has been disclosed. You may fit in a surface and a bottom face. Further, in the embodiment of the present invention, a configuration having two fixing members 102 in total, one for each housing side surface 101c, is disclosed. However, as an application example, for example, fixing members arranged on both side surfaces are used. The integral 102 may be formed in a U shape or a cylindrical shape. In this case, the rail grooves 101e, 101f, and 101g are not necessarily required in the housing 101a.
That is, the housing 101a is a columnar body such as an elliptical column or a quadrangular column, the fixing member 102 has a shape in which the side surface of the columnar body constituting the housing 101a is wound, and the fixing member 102 forms the housing 101a. If the structure cannot be rotated from the center of the bottom surface of the column body, the fixing member 102 can translate the side surface of the housing 101a, which is a column body, without providing the rail groove in the housing 101a. A rack 101d formed on a part of the side surface of the housing 101a and a ratchet can also be configured.

  The embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and other modifications and application examples are provided without departing from the gist of the present invention described in the claims. including.
