DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, several embodiments of the present disclosure will be described in detail with reference to the drawings.

[0010] [Embodiment 1] First, a description will be given of embodiment 1. The display device according to this embodiment includes a display panel (display panel that displays images, etc.) DP (shown by virtual lines in FIG. 1), a chassis 100, and a rear cabinet 200 shown in Fig. 1, and is premised on a structure in which rear cabinet 200 is fixed to chassis 100. Note that Fig. 1 is an exploded perspective view showing the display panel DP, chassis 100, and rear cabinet 200 extracted from the display device, and shows the state as viewed from the chassis 100 side (the state as viewed from the front side of the display device).

[0011] -Explanation of chassis and hook parts- 2 is a perspective view of the chassis 100 as seen from the rear side. A plurality of hook members (first engaging members) 110 are attached to the rear surface of the chassis 100 (the surface facing the rear cabinet 200). In the first embodiment, the chassis 100 corresponds to the first member recited in the claims. The hook members 110 can be attached to any position on the rear surface of the chassis 100 by means of screws, adhesive, fitting, or the like, but the attachment positions, number, and attachment structure of the hook members 110 are not particularly limited in the present disclosure.

[0012] The specific configuration of the hook member 110 will be described with reference to Fig. 3. In Fig. 3, (a) is a perspective view of the hook member 110 seen from above, and (b) is a perspective view of the hook member 110 seen from below. For ease of explanation, the surface of the hook member 110 that abuts against the chassis 100 is referred to as the bottom surface.

[0013] In the following description, the longitudinal direction of the hook member 110 is referred to as the X direction, and the left direction in FIG. 3(a) (more specifically, the upper left direction in FIG. 3(a)) will sometimes be referred to as the X1 direction, and the right direction in FIG. 3(a) (more specifically, the lower right direction in FIG. 3(a)) will sometimes be referred to as the X2 direction. The shorter direction of the hook member 110, perpendicular to the X direction, is referred to as the Y direction, and the front direction of the page in FIG. 3(a) (more specifically, the lower left direction in FIG. 3(a)) will sometimes be referred to as the Y1 direction, and the back direction of the page in FIG. 3(a) (more specifically, the upper right direction in FIG. 3(a)) will sometimes be referred to as the Y2 direction. The height direction of the hook member 110 (the vertical direction in FIG. 3(a)) will sometimes be referred to as the Z direction, and the upward direction in FIG. 3(a) will sometimes be referred to as the Z1 direction, and the downward direction in FIG. 3(a) will sometimes be referred to as the Z2 direction.

[0014] As shown in FIG. 3, the hook member 110 generally has a base portion 111 and a pair of engaging arms (engaging ribs) 112.

[0015] The base portion 111 is a plate-like member having a substantially rectangular shape, and when the hook member 110 is attached to the chassis 100, the lower surface (the surface located on the Z2 direction side) of the base portion 111 faces or abuts against the chassis 100. Fig. 4 is a cross-sectional view (a cross-sectional view taken at a position corresponding to line IV-IV in Fig. 3(a)) showing a state in which the hook member 110 is attached to the chassis 100. As shown in Fig. 4, with the lower surface (the surface located on the Z2 direction side) of the base portion 111 abutting against the chassis 100, the hook member 110 is attached to the back surface of the chassis 100 by means of screwing, adhesive bonding, fitting, or the like.

[0016] 3, the engaging arms 112 are erected so as to protrude upward (in the Z1 direction) from the upper surface of the base portion 111, and the two engaging arms 112 are arranged side by side so as to face each other in the hook member 110. The arrangement direction of the two opposing engaging arms 112 coincides with the longitudinal direction (X direction) of the base portion 111.

[0017] Each of the engaging arms 112 has a mountain-shaped protrusion 112A that bulges toward the opposing other engaging arm 112. That is, the distance between the two opposing engaging arms 112 narrows at the apex of the protrusion 112A, and then widens again from the apex toward the tip of the engaging arm 112. When the rear cabinet 200 is fixed to the chassis 100, an engaging protrusion 210 (see FIG. 6), which will be described later and which protrudes from the rear cabinet 200 (protruding in the Z2 direction), is fitted into and engaged with the protrusion 112A, as will be described later. The configuration of the engaging protrusion 210 and the engagement operation of the engaging protrusion 210 will be described later.

[0018] Each engaging arm 112 has a leg 112B extending downward (in the Z2 direction) from the lower side (Z2 side) of the protrusion 112A. The width of the protrusion 112A in the Y direction is the same as the width of the leg 112B in the Y direction.

[0019] As a feature of the present embodiment, an opening 111A is provided in the base portion 111 between the two engaging arms 112. The shape of this opening 111A in a plan view (the shape when viewed from the direction along the Z direction) is substantially rectangular (approximately oblong), and the length dimension (opening dimension) of the opening 111A in the X direction is set to be shorter than the length dimension of the base portion 111 in the X direction by a predetermined dimension, and the length dimension (opening dimension) of the opening 111A in the Y direction is set to be shorter than the length dimension of the base portion 111 in the Y direction by a predetermined dimension. As an example, the length dimension of the opening 111A in the X direction is set to be approximately ⅓ of the length dimension of the base portion 111 in the X direction. Furthermore, the length dimension of the opening 111A in the Y direction is set to be approximately ⅓ of the length dimension of the base portion 111 in the Y direction. These dimensional ratios are not limited to these. The opening shape of this opening 111A is determined in relation to the shape of the engaging protrusion 210 described below. Specifically, the opening shape is determined to be such that the tip portion of the engaging protrusion 210 can be inserted therein. The relationship between the shape of the opening 111A and the shape of the engaging protrusion 210 will be described later.

[0020] Furthermore, the opening 111A is formed at a position approximately at the center in the short-side direction (Y direction) of the base portion 111, but is set at a position slightly closer to the X1 direction than the center in the longitudinal direction (X direction) of the base portion 111. This is because, when screws are used to attach the hook member 110 to the chassis 100, an attachment area to the chassis 100 is ensured on the X2 side of the base portion 111 in the longitudinal direction (X direction) by, for example, providing a screw hole (not shown) in the base portion 111. In this case, instead of using screws on the X1 side of the base portion 111 in the longitudinal direction (X direction), a configuration is adopted in which a locking protrusion is provided on the back surface of the chassis 100 and the locking protrusion is locked to the base portion 111. The means for attaching the hook member 110 to the chassis 100 is not particularly limited.

[0021] Each engaging arm 112 (more specifically, leg 112B) is continuous with the opening edge of the opening 111A (the opening edge located on the X1 direction side and extending in the Y direction, and the opening edge located on the X2 direction side and extending in the Y direction), and extends upward (in the Z1 direction) from the opening edge. Therefore, in a plan view of the hook member 110, each protrusion 112A is located inside the opening edge of the opening 111A (located above the opening 111A).

[0022] Furthermore, grooves (notches) 111B that penetrate in the vertical direction and open (continue) to the openings 111A in the X direction are provided on both sides (positions on the Y1 direction side and the Y2 direction side) of each engaging arm 112 in the horizontal extension direction (Y direction) of the base portion 111. This is to reduce the rigidity around the base portions (portions where the leg portions 112B are connected to the base portion 111) of each engaging arm 112, making the engaging arms 112 more likely to elastically deform (to make the base portions of the engaging arms 112 more likely to be elastically deformed so that cracks do not occur during the engagement operation of the engaging protrusions 210, which will be described later).

[0023] -Description of rear cabinet and engagement protrusions- FIG. 5 is a perspective view of rear cabinet 200 as seen from the front side. Rear cabinet 200 is a member that covers the rear side of chassis 100 by being attached to chassis 100. A plurality of engagement protrusions (second engagement members) 210 are provided on the front side of rear cabinet 200 (the surface facing chassis 100). In the first embodiment, rear cabinet 200 corresponds to the second member recited in the claims. The number of engagement protrusions 210 is the same as the number of hook members 110 on chassis 100, and the positions where the engagement protrusions 210 are formed also face the attachment positions of hook members 110 on chassis 100. The engagement protrusions 210 can be molded integrally with rear cabinet 200 from resin.

[0024] FIG. 6 is a perspective view showing one of the multiple engagement protrusions 210 provided on the front surface of the rear cabinet 200. The engagement protrusion 210 includes a base 211 and a head 212, and has a recess 213 near the boundary between the base 211 and the head 212. The recess 213 is configured as a narrowed portion whose dimension in the X direction is set shorter than the dimensions of the base 211 and the head 212 in the X direction. The recess 213 is a portion that fits with the protrusion 112A of the hook member 110 (the protrusion 112A is inserted and fitted into the recess 213). The base 211 is formed to stand upright from the rear cabinet 200, but its height does not need to be the same for all of the engagement protrusions 210. In other words, the surface of the rear cabinet 200 on which the engagement protrusions 210 are formed is not necessarily a uniform plane, and therefore the distance between the opposing surfaces of the rear cabinet 200 and the chassis 100 varies depending on the location where the engagement protrusion 210 is formed. That is, the height of base 211 is set in accordance with the distance between the opposing surfaces of rear cabinet 200 and chassis 100 at the locations where each engaging protrusion 210 is formed.

[0025] -Engagement work of the engagement protrusion 210- Next, we will explain the operation of fitting the engaging protrusions 210 between the engaging arms 112 of the hook members 110 to engage them when fixing the rear cabinet 200 to the chassis 100. Figure 7 is a cross-sectional view for explaining the operation in this engaging operation, where (a) shows the state at the start of the engaging operation and (b) shows the state when the engagement is completed.

[0026] First, as shown in FIG. 7(a), the head 212 of the engaging protrusion 210 is pressed against the convex portion 112A of each engaging arm 112 so as to be inserted into the space between the engaging arms 112. This pressing force causes the engaging arms 112 to spread outward, and when the distance (distance in the X direction) between the convex portions 112A reaches the dimension (dimension in the X direction) of the head 212 of the engaging protrusion 210, the head 212 moves over the convex portion 112A and reaches the leg portion 112B (see FIG. 7(b)). As a result, each engaging arm 112 returns to its original shape, and the convex portion 112A of each engaging arm 112 is inserted (fitted) into each recess 213 of the engaging protrusion 210, so that the engaging protrusion 210 fits between and engages with the engaging arms 112 (details of this engaged state will be described later). By performing such an engagement operation at the positions where each hook member 110 and each engagement protrusion 210 are disposed, rear cabinet 200 is fixed to chassis 100.

[0027] In this way, by engaging the hook members 110 attached to the chassis 100 with the engaging protrusions 210 provided on the rear cabinet 200, the rear cabinet 200 can be attached to the chassis 100 and fixed. In this fixing method, compared to the conventional method of fixing the rear cabinet in which screws are fastened from the rear side of the display device, the number of screws exposed on the rear surface of the device can be significantly reduced, and the aesthetic appearance of the device can be improved. Furthermore, with this configuration, the number of screws exposed on the rear surface of the device can be significantly reduced (the number of screws used to fasten rear surface cabinet 200 can be reduced), but it is not limited to completely eliminating screws exposed on the rear surface of the device. In other words, rear surface cabinet 200 does not have to be fastened only by the engagement between hook member 110 and engaging protrusion 210, and screws (screws fastened from the rear surface side of the display device) may be used as an auxiliary.

[0028] -Description of dimensions of each part- Next, the dimensional relationships between the engaging arm portion 112, the opening 111A, and the engaging protrusion portion 210 will be described.

[0029] 4, the overall height dimension (length dimension in the Z direction) of the engaging arm 112 is defined as A1, and the length dimension from the convex portion 112A of the engaging arm 112 to the upper surface (surface on the Z1 direction side) of the base portion 111 is defined as A2. Also, the spacing dimension between the convex portions 112A of the engaging arm 112 is defined as B1, the opening dimension of the opening 111A in the X direction is defined as B2, and the opening dimension in the Y direction is defined as B3 (see FIG. 3(b)).

[0030] 6, the overall height dimension of the engaging protrusion 210 (the length dimension in the Z direction in FIG. 6) is C1, and the length dimension from the recess 213 of the engaging protrusion 210 to the tip position (the tip position on the Z2 direction side) is C2. Furthermore, the length of the head 212 of the engaging protrusion 210 in the X direction is D1, and the length in the Y direction is D2.

[0031] The dimension B1 is set shorter than the dimension D1. This prevents the protrusions 112A of the engaging arms 112 from slipping out of the recesses 213 of the engaging protrusions 210. This embodiment is characterized in that the dimension B2 is set longer than the dimension D1, and the dimension B3 is set longer than the dimension D2. Furthermore, the dimension A2 is set shorter than the dimension C2. As a result, when the engaging protrusions 210 are fitted between the engaging arms 112 and engaged as shown in FIG. 7(b), the tip of the engaging protrusions 210 is inserted into the opening 111A. In other words, the tip of the engaging protrusions 210 is positioned inside the opening 111A, and the tip of the engaging protrusions 210 and the base 111 of the hook member 110 are held in an overlapping state in the X and Y directions. Compared to the prior art (where the tip of the engaging protrusion is positioned higher than the base of the hook member), this overlapping dimension allows the rear cabinet 200 to be positioned closer to the chassis 100, resulting in a thinner display device. The dimensional relationship is set so that A1<{C1-(C2-A2)} holds. As a result, when the engaging protrusion 210 is fitted between and locked to the engaging arms 112 as shown in FIG. 7(b), the upper ends (tips in the Z1 direction) of the engaging arms 112 do not interfere with the front surface of the rear cabinet 200.

[0032] -Effects of the embodiment- As described above, one way to reduce the thickness of a display device is to move the engagement position, where the protrusions 112A of the engagement arms 112 fit into the recesses 213 of the engagement protrusions 210, closer to the base 111. In this embodiment, the tip of the engagement protrusion 210 is positioned inside the opening 111A, and the tip of the engagement protrusion 210 and the base 111 of the hook member 110 are held in an overlapping state in the X and Y directions, thereby enabling the engagement position to be moved closer to the base 111 (see FIG. 7(b)). This allows for a thinner display device than conventional display devices. For example, the thickness of the display device can be reduced to about one-third of that of conventional display devices. The dimensions that allow this reduction in thickness are not limited to these values.

[0033] In this embodiment, each of the engaging arms 112 is continuous with the edge of the opening 111A and extends upward (in the Z1 direction) from the edge of the opening 111A. Therefore, in a configuration in which the opening 111A is provided between the engaging arms 112, it is possible to maximize the opening area of the opening 111A.

[0034] [Embodiment 2] Next, a second embodiment will be described. In this embodiment, the configuration of the base portion of each engaging arm portion 112 (the portion where leg portion 112B is connected to base portion 111) is different from that of the first embodiment described above. The other configurations are the same as those of the first embodiment. Here, the differences from the first embodiment will be mainly described.

[0035] When the display device is made thinner by using the configuration of the first embodiment described above (when the display device is made thinner by moving the engagement position between the engaging protrusion 210 and each engaging arm 112 closer to the base 111), the amount by which each engaging arm 112 is pushed outward increases during the engagement operation of the engaging protrusion 210, which raises the concern that cracks may occur at the base of each engaging arm 112. The present embodiment relates to an improvement of the hook member 110 in consideration of this point.

[0036] FIG. 8 shows a hook member 110 according to this embodiment, where (a) is a perspective view of the hook member 110 as viewed from above, and (b) is a perspective view of the hook member 110 as viewed from below. As shown in these figures, the hook member 110 according to this embodiment has a base portion 111, and a groove 300 (a groove recessed downward (in the Z2 direction); a recess) extending along the Y direction is provided on the upper surface of the base portion (the portion where the leg portion 112B connects to the base portion 111) of each engaging arm portion 112. The depth of this groove 300 is determined in advance through experiments and simulations as a dimension that ensures sufficient elasticity of the engaging arm portion 112 during the engagement operation of the engaging protrusion 210. Similar grooves are also formed on the outer sides of each engaging arm portion 112 in the Y direction (the Y1 and Y2 direction sides). This shape enables the hook member 110 to be removed from a mold when it is molded.

[0037] According to this embodiment, sufficient elasticity can be ensured at the base portion of each engaging arm portion 112, and cracks can be reliably prevented from occurring at the base portion of each engaging arm portion 112 during the engagement operation of the engaging protrusion portion 210.

[0038] [Embodiment 3] Next, a third embodiment will be described. In this embodiment, the configuration of the base portion of each engaging arm 112 (the portion where leg portion 112B is connected to base portion 111) is also different from that of the first embodiment. The other configurations are the same as those of the first embodiment. Here, the differences from the first embodiment will be mainly described.

[0039] 9A and 9B are diagrams showing a hook member 110 according to this embodiment, where (a) is a perspective view of the hook member 110 as seen from above, and (b) is a perspective view of the hook member 110 as seen from below. As shown in these figures, the hook member 110 according to this embodiment has an opening 310 extending from the leg portion 112B of the engaging arm portion 112 to the base portion 111. The shape of this opening 310 has been determined in advance through experiments and simulations to have dimensions that ensure sufficient elasticity of the engaging arm portion 112 during the engaging operation of the engaging protrusion 210.

[0040] In this embodiment as well, sufficient elasticity can be ensured at the base of each engaging arm 112, and cracks can be reliably prevented from occurring at the base of each engaging arm 112 during the engagement operation of the engaging protrusion 210.

[0041] [Embodiment 4] Next, a fourth embodiment will be described. Fig. 10 shows a hook member 110 according to the present embodiment, where (a) is a perspective view of the hook member 110 seen from above, and (b) is a perspective view of the hook member 110 seen from below. As shown in these figures, the hook member 110 according to the present embodiment has both the groove 300 in the second embodiment and the opening 310 in the third embodiment.

[0042] According to this embodiment, the action of both the groove 300 and the opening 310 ensures sufficient elasticity at the base of each engaging arm 112, thereby reliably preventing cracks from occurring at the base of each engaging arm 112 during the engagement operation of the engaging protrusion 210.

[0043] [Embodiment 5] Next, a fifth embodiment will be described. In this embodiment, the configuration of the base portion 111 is different from that of the first embodiment. The other configurations are the same as those of the first embodiment. Here, the differences from the first embodiment will be mainly described.

[0044] 11 is a diagram relating to this embodiment, in which (a) is a perspective view of the hook member 110 as seen from above, (b) is a perspective view of the hook member 110 as seen from below, and (c) is a cross-sectional view showing the hook member 110 attached to the chassis 100. As shown in these figures, the hook member 110 according to this embodiment has a stopper portion 400 integrally formed on the lower side of the base portion 111 (below the opening 111A).

[0045] The stopper portion 400 is connected to both sides of the opening edge of the opening 111A in the X direction and extends along the Y direction. An upper surface 400a of the stopper portion 400 is set at approximately the same height as the lower surface 111a of the base portion 111, and a lower surface 400b of the stopper portion 400 is set at a position protruding from the lower surface 111a of the base portion 111 by a predetermined distance.

[0046] 11(c), an opening 100a that is slightly larger than the shape of the stopper portion 400 in a plan view (the shape when viewed from the direction along the Z direction) is provided at the position on the chassis 100 where the hook member 110 is attached.

[0047] The attachment structure of the hook member 110 configured in this manner to the chassis 100 is such that, with the stopper portion 400 inserted into the opening 100a formed in the chassis 100, the lower surface 111a of the base portion 111 abuts against the back surface of the chassis 100, and in this state the hook member 110 is attached to the back surface of the chassis 100.

[0048] According to this embodiment, if the pushing amount of the engaging protrusion 210 becomes larger than a predetermined amount during the engagement operation of the engaging protrusion 210 (if the pushing force is too large and the pushing amount temporarily becomes larger than the pushing amount at the predetermined engagement position), causing the head 212 to come close to the chassis 100, the head 212 will come into contact with the stopper portion 400, preventing it from interfering with the components (circuit board, etc.) provided on the chassis 100. This makes it possible to avoid damage to the components. The thickness dimension (dimension in the Z direction) of the stopper portion 400 is determined in advance by experiment or simulation as a dimension that can adequately withstand the pushing force when the head 212 comes into contact.

[0049] [Embodiment 6] Next, a sixth embodiment will be described. This embodiment also has a configuration in which a stopper portion 400 is integrally formed on the lower side of the base portion 111 (below the opening 111A), but the configuration of the base portion 111 and the attachment state of the hook member 110 to the chassis 100 are different from those of the fifth embodiment. The other configurations are the same as those of the fifth embodiment. Here, the differences from the fifth embodiment will be mainly described.

[0050] FIG. 12 is a diagram relating to this embodiment, in which (a) is a perspective view of the hook member 110 as seen from above, (b) is a perspective view of the hook member 110 as seen from below, and (c) is a cross-sectional view showing the hook member 110 attached to the chassis 100.

[0051] As shown in FIG. 12(c), in this embodiment, no opening is provided in the chassis 100 at the position where the hook member 110 is attached.

[0052] Furthermore, a plurality of protrusions 111b having protrusion dimensions that substantially match the thickness dimension of the stopper portion 400 (the dimension from the lower surface 111a of the base portion 111 to the lower surface 400b of the stopper portion 400) are provided on the lower surface 111a of the base portion 111 of the hook member 110. In the example shown in Fig. 12, the protrusions 111b are provided in six locations.

[0053] In the attachment structure of the hook member 110 thus configured to the chassis 100, when the hook member 110 is placed on the back surface of the chassis 100, the lower surface 400b of the stopper portion 400 and the tip ends of the protrusions 111b come into contact with the back surface of the chassis 100. In this state, the hook member 110 is attached to the back surface of the chassis 100 by means of adhesion or the like.

[0054] According to this embodiment, in addition to the effects of the fifth embodiment described above, it is possible to stably attach the hook member 110 to the rear surface of the chassis 100 without providing an opening in the chassis 100.

[0055] The lower surface 400b of the stopper portion 400 may be flush with the lower surface 111a of the base portion 111. In this case as well, it becomes possible to stably attach the hook member 110 to the back surface of the chassis 100 without providing an opening in the chassis 100.

[0056] [Embodiment 7] Next, a description will be given of embodiment 7. Figure 13 shows a hook member 110 according to this embodiment, where (a) is a perspective view of the hook member 110 seen from above, and (b) is a perspective view of the hook member 110 seen from below.

[0057] As shown in these figures, in the hook member 110 according to this embodiment, the width dimension (dimension in the Y direction) of the stopper portion 400 is set to be larger than those in the above-described embodiments 5 and 6. As a result, even if the head portion 212 of the engaging protrusion portion 210 comes close to the chassis 100, the head portion 212 can be reliably brought into contact with the stopper portion 400, and interference with the components provided on the chassis 100 can be prevented.

[0058] -Other embodiments- The embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present disclosure should not be interpreted solely by the above-described embodiments, but should be defined by the claims. Furthermore, all modifications within the scope and meaning equivalent to the claims are included.

[0059] For example, in each of the above-described embodiments, the hook member 110 is attached to the chassis 100, and the engaging protrusion 210 is formed on the rear cabinet 200. However, the present disclosure is not limited to this, and the engaging protrusion 210 may be provided on the chassis 100, and the hook member 110 may be provided on the rear cabinet 200.

[0060] In addition, in each of the above-described embodiments, each engaging arm 112 is configured to be continuous with the edge of opening 111A. However, the present disclosure is not limited to this, and each engaging arm 112 may be configured to protrude upward from a position set back from the edge of opening 111A (a position spaced apart from the edge of opening 111A in the X direction). [Industrial Applicability]
