That is, the upright portion 11 may have a polygonal cylindrical shape. In addition, the upright portion 11 is divided into two parts, a portion in which the first through-hole 15 and the second screw hole 17 are formed and a portion in which the second through-hole 16 is formed, and when viewed from below ( It may have a substantially cylindrical shape with two substantially semicircles (when viewed in the +Z direction).

Next, a method for attaching the lighting fixture 100 according to the first embodiment of the present invention to a wall surface will be described. FIG. 5 is a diagram illustrating a method of attaching the lighting fixture 100 according to the first embodiment of the present invention to a wall surface. First, as shown in FIG. 5A, the fixing member 1 is fixed to the ceiling surface A, which is a wall surface, using screws. The fixing member 1 is fixed to the ceiling surface A using the first screw holes 13 and screws, but illustration of the screws is omitted in FIG. 5(a).

Next, as shown in FIGS. 5(b) and 5(c), the mounting member 2 is held so that the lid portion 21 is slanted with respect to the ceiling surface A, and the first through hole 16 is inserted into the second through hole 16. The first hook portion 29 of the hook portion 23 is inserted to hook the first hook portion 23 to the second through hole 16 . Then, the first convex portion 28 of the first spring portion 22 is brought into contact with the rising portion 11, and the mounting member 2 is pushed in the +Z direction. At this time, the portion T1 surrounded by the dotted line in FIG. Then, as the mounting member 2 is pushed in the +Z direction, the point of contact between the T1 portion and the rising portion 11 approaches the apex of the first convex portion 28, and as shown in FIG. The vertex touches the rising portion 11 .

Since the first spring portion 22 has an elastic force in a direction (±Y direction) perpendicular to the rising portion 11, it is pressed by the rising portion 11 and moves in the -Y direction as shown in FIG. 5(c). It deforms elastically. When the mounting member 2 is pushed in the +Z direction while the first spring portion 22 is elastically deformed in the -Y direction, when the apex of the first protrusion 28 reaches the position of the first through hole 15, it will stand up. The pressure applied to the first spring portion 22 by the upper portion 11 is released, and the first convex portion 28 of the first spring portion 22 is inserted into the first through hole 15 . As a result, the state shown in FIG. 5(d) is obtained. As described above, the lighting fixture 100 according to the first embodiment of the present invention is attached to the ceiling surface A.

Finally, the fixing member 1 and the drop prevention fixing portion 25 of the mounting member 2 are fixed using the second screw holes 17 and screws. Even if this work is not performed, the mounting member 2 can be removed by inserting the first convex portion 28 into the first through hole 15 and inserting the first claw portion 29 into the second through hole 16 . does not drop from the fixed member 1. However, if the first convex portion 28 or the first claw portion 29 deteriorates due to long-term use of the lighting fixture 100 , the mounting member 2 may come off from the fixing member 1 . Therefore, just in case, in the present embodiment, the second screw hole 17 and screws are used to fix the fixing member 1 and the drop prevention fixing portion 25 of the mounting member 2 .

The work of removing the lighting fixture 100 according to the present embodiment from the wall surface is basically carried out in the reverse order of the mounting work. First, the screw is removed from the second screw hole 17 to release the fixation between the fixing member 1 and the fall prevention fixing portion 25 . Then, the portion of the lid portion 21 where the first spring portion 22 is provided is pulled in the -Z direction to tilt the lid portion 21, thereby elastically deforming the first spring portion 22 in the -Y direction. When the mounting member 2 is pulled in the −Z direction as it is, the first spring portion 22 is removed from the first through hole 15 and the first hook portion 23 from the second through hole 16, and is attached to the fixing member 1. The member 2 is removed. Finally, the fixing member 1 is removed from the ceiling surface A. As described above, the lighting fixture 100 according to the first embodiment is removed from the ceiling surface A.

FIG. 6 is a schematic cross-sectional view illustrating the positional relationship among the first spring portion 22, the first hook portion 23, and the rising portion 11 of the lighting device 100 according to this embodiment. FIG. 6 schematically shows only the upright portion 11, the fixing surface 12, the lid portion 21, the first spring portion 22 and the first hook portion 23 of the lighting fixture 100 according to the present embodiment. Since the fixing surface 12 is in contact with the wall surface, the position of the fixing surface 12 is also the position of the wall surface.

As shown in FIG. 6, of the endpoints of the first spring portion 22, a point P farthest from the first hook portion 23 in the direction (±Y direction) perpendicular to the rising portion 11 and the first hook A direction perpendicular to the rising portion 11 (±Y direction) is longer than the distance L2 between the inner surfaces of the rising portions 11 . That is, in the present embodiment, distance L1 in the ±Y direction between point P and point Q is longer than distance L2 between the inner surfaces of rising portion 11 . Therefore, the first spring portion 22 is engaged with the rising portion 11 and the first hook portion 23 is engaged with the rising portion 11 . More specifically, the first spring portion 22 and the first hook portion 23 are engaged with the rising portion 11 by utilizing the outward force of the rising portion 11 .

Further, as shown in FIG. 6, a point R closest to the wall surface on the surface of the first spring portion 22 facing the rising portion 11 The distance L3 in the direction (±Y direction) perpendicular to the rising portion 11 between the point S closest to the wall surface on the surface facing the , is shorter than the distance L2 between the inner surfaces of the rising portion 11 . That is, in the present embodiment, distance L3 in the ±Y direction between point R and point S is shorter than distance L2 between the inner surfaces of rising portion 11 . In the present embodiment, the distance L3 is shorter than the distance L2 both before and after attaching the mounting member 2 to the fixing member 1. It should be shorter than the distance L2.

In the present embodiment, since the rising portion 11 is cylindrical, the distance L2 between the inner surfaces of the rising portion 11 is the inner diameter of the rising portion 11 and has the same length everywhere. However, since the rising portion 11 may have a polygonal tubular shape, the distance L2 between the inner surfaces of the rising portion 11 may vary depending on the location. In this case, the distance L2 between the inner surfaces of the rising portions 11 is the distance L2 between the inner surfaces of the rising portions 11 in the same cross section in which the distance L2 between the inner surfaces of the rising portions 11 is shown.

The distance L1, the distance L2, and the distance L3 are determined by the magnitude of the elastic force of the first spring portion 22, the shape of the first convex portion 28, the shape of the first hook portion 23, the shape of the first through hole 15, and the shape of the first through hole 15. It is appropriately determined depending on the size, the shape and size of the second through hole 16, and the like.

Further, as shown in FIG. 6, the first spring portion 22 has a surface that is closer to the wall surface than a surface that is in contact with the rising portion 11 in a direction parallel to the rising portion 11 (±Z direction). An obtuse angle C1 is formed between 11 and the opposite surface that is closer to the wall surface. The angle of the obtuse angle C1 is appropriately determined according to the magnitude of the elastic force of the first spring portion 22, the shape and size of the first through hole 15, and the like.

As described above, in the luminaire 100 according to the present embodiment, the first spring portion 22 has an elastic force in a direction perpendicular to the rising portion 11, so that the luminaire 100 can be easily attached to the wall surface. can. The lighting device 100 according to the present embodiment can be mounted by simply pushing the mounting member 2 into the fixing member 1 after hooking the first hooking portion 23 on the second through hole 16 . The member 2 can be attached to a fixed member 1 fixed to the wall. In other words, in the operation of attaching the mounting member 2 to the fixing member 1 , there is no action that should be performed simultaneously with the action of pushing the mounting member 2 into the fixing member 1 . That is, in the work of attaching the mounting member 2 to the fixing member 1, the lighting fixture 100 according to the present embodiment does not need to perform two or more operations at the same time. Therefore, the lighting apparatus 100 according to the present embodiment can be easily attached to the fixing member 1 with the mounting member 2, so that the lighting apparatus 100 can be easily attached to the wall surface.

Moreover, the lighting fixture 100 according to the present embodiment can be more easily attached to the wall surface. The luminaire 100 according to the present embodiment has a point R closest to the wall surface on the surface of the first spring portion 22 facing the rising portion 11 and a point R on the surface of the first hook portion 23 that A distance L3 in the direction perpendicular to the rising portion 11 between the point S closest to the wall surface on the surface facing the upper portion 11 is shorter than the distance L2 between the inner surfaces of the rising portion 11 . Therefore, in the work of attaching the mounting member 2 to the fixing member 1 , the lighting fixture 100 according to the present embodiment makes it easy to bring the first spring portion 22 into contact with the rising portion 11 .

Furthermore, the luminaire 100 according to this embodiment can be more easily attached to the wall surface. The first spring portion 22 of the lighting device 100 according to the present embodiment faces the rising portion 11 with a surface closer to the wall surface in contact with the rising portion 11 in a direction parallel to the rising portion 11. The angle between the face that is closer to the wall surface is an obtuse angle. Therefore, in the operation of attaching the mounting member 2 to the fixing member 1 , the lighting fixture 100 according to the present embodiment causes the first spring portion 22 and the rising portion 11 to abut on each other, and then the mounting member 2 is attached to the fixing member 1 . This is because it is easy to push the .

Moreover, the lighting fixture 100 according to the present embodiment can be easily removed from the wall surface. The luminaire 100 according to the present embodiment can be fixed simply by pulling the portion of the lid portion 21 where the first spring portion 22 is provided, tilting the lid portion 21, and pulling the mounting member 2 in the -Z direction. The mounting member 2 can be removed from the member 1. Therefore, in the lighting fixture 100 according to the present embodiment, the mounting member 2 can be easily removed from the fixing member 1, so that it can be easily removed from the wall surface.

Now consider a luminaire in the first case described below. First, two L-shaped first protrusions are provided inside the rising portion 11 of the fixing member 1 instead of the first through-hole 15 and the second through-hole 16 . Then, instead of the first spring portion 22 and the first hooking portion 23, the mounting member 2 is provided with two second projections that fit into the first projections. The fitting between the first projection and the second projection is performed by the second projection coming into contact with the inner corner of the L-shape of the first projection. After the fixing member and the mounting member are aligned so that the first projections and the second projections are alternately arranged, the mounting member is rotated so that the inner corner of the L-shape of the first projection engages the second projection. It is a mechanism in which the protrusions of the

In the first case, when the lamp attached to the mounting member rotates in order to adjust the light distribution, the mounting member rotates due to its influence, and the first protrusion and the second protrusion are not fitted. It could have come off. That is, in the lighting fixture of the first case, when the lamp rotates, the mounting member may come off from the fixing member, and the lamp may fall.

On the other hand, the lighting fixture 100 according to the present embodiment can prevent the mounting member 2 from coming off the fixing member 1 and the lighting fixture 3 from falling due to the rotation of the lighting fixture 3 . Since the first projection 28 is inserted into the first through hole 15 and the first claw 29 is inserted into the second through hole 16, even if the lamp 3 rotates, the first It is possible to prevent the mounting member 2 from rotating by contacting the protrusion 28 with the edge of the first through-hole 15 or contacting the first claw 29 with the edge of the second through-hole 16 . Because you can.

In the present embodiment, the first engagement receiving portion and the second engagement receiving portion are assumed to be through holes, but in the present invention, the first engagement receiving portion and the second engagement receiving portion The receiving portion may also be a recess. Of course, the recess and the through hole may be combined by using the recess as the first engagement receiving portion and the through hole as the second engagement receiving portion. When forming a recess, a recess is formed in the raised portion 11 so that the recessed portion is inside the raised portion 11 so that the first engaging portion or the second engaging portion engages with the recessed portion of the recess. do.

Further, in the present embodiment, the lamp 3 is assumed to be rotatable, but in the present invention, the lamp 3 may be non-rotatable and is not particularly limited.

Furthermore, although the first hooking portion 23 is molded integrally with the first connecting portion 24 in the present embodiment, the first hooking portion 23 is formed on the first connecting portion 24 by molding separately. You can connect. Similarly, in the present embodiment, the first spring portion 22 is molded separately from the first connection portion 24 and is connected to the first connection portion 24, but the first spring portion 22 and the first The connecting portion 24 may be molded integrally, or the first spring portion 22, the first hook portion 23 and the first connecting portion 24 may be integrally molded. Moreover, the mounting member 2 of the lighting fixture 100 according to the present embodiment does not include the first connection portion 24, and the first spring portion 22 and the first hook portion 23 are directly connected to the lid portion 21, respectively. can be

However, if the second projection 48 or the third projection 29 deteriorates over time due to long-term use of the lighting fixture, the mounting member 4 may come off from the fixing member 1 . Therefore, just in case, in the present embodiment, the second screw hole 17 and screws are used to fix the fixing member 1 and the drop prevention fixing portion 25 of the mounting member 4 .

The work of removing the lighting fixture according to the present embodiment from the wall surface is basically carried out in the reverse order of the mounting work. First, the screw is removed from the second screw hole 17 to release the fixation between the fixing member 1 and the fall prevention fixing portion 25 of the mounting member 4 . Then, the lid portion 21 is pulled in the -Z direction, the second spring portion 42 is elastically deformed in the +X direction, and the third spring portion 43 is elastically deformed in the -X direction. When the mounting member 4 is pulled in the -Z direction, the second spring portion 42 is removed from the first through hole 15, the third spring portion 43 is removed from the second through hole 16, and the fixing member 1 is removed.

As described above, the lighting fixture according to the present embodiment is removed from the ceiling surface A.

FIG. 9 is a schematic cross-sectional view illustrating the positional relationship between the second spring portion 42, the third spring portion 43, and the upright portion 11 of the lighting fixture according to this embodiment. FIG. 9 schematically shows only the upright portion 11, the fixing surface 12, the lid portion 21, the second spring portion 42 and the third spring portion 43 of the lighting fixture according to the present embodiment. Since the fixing surface 12 is in contact with the wall surface, the position of the fixing surface 12 is also the position of the wall surface.

As shown in FIG. 9, a point H farthest from the third spring portion 43 in a direction (±Y direction) perpendicular to the upright portion 11 among endpoints of the second spring portion 42 and a third spring In the direction perpendicular to the rising portion 11 (±Y direction) is longer than the distance L2 between the inner surfaces of the rising portions 11 . That is, in the present embodiment, distance L5 in the ±Y direction between point H and point I is longer than distance L2 between the inner surfaces of rising portion 11 . Therefore, in the present embodiment, the second spring portion 42 engages with the rising portion 11 and the third spring portion 43 engages with the rising portion 11 . More specifically, the second spring portion 42 and the third spring portion 43 are engaged with the rising portion 11 using the outward force of the rising portion 11 .

Further, as shown in FIG. 9, a point J closest to the wall surface of the surface of the second spring portion 42 facing the rising portion 11 and a point J of the surface of the third spring portion 43 facing the rising portion 11 The distance L6 in the direction (±Y direction) perpendicular to the rising portion 11 between the point K closest to the wall surface on the surface facing the , is shorter than the distance L2 between the inner surfaces of the rising portion 11 . That is, in the present embodiment, the distance L6 between the points J and K in the ±Y direction is shorter than the distance L2 between the inner surfaces of the rising portions 11 . In the present embodiment, the distance L6 is shorter than the distance L2 both before and after attaching the mounting member 2 to the fixing member 1. It should be shorter than the distance L2.

In the present embodiment, since the rising portion 11 is cylindrical, the distance L2 between the inner surfaces of the rising portion 11 is the inner diameter of the rising portion 11 and has the same length everywhere. However, since the rising portion 11 may have a polygonal tubular shape, the distance L2 between the inner surfaces of the rising portion 11 may vary depending on the location. In this case, the distance L2 between the inner surfaces of the rising portions 11 is the distance L2 between the inner surfaces of the rising portions 11 in the same cross section in which the distance L2 between the inner surfaces of the rising portions 11 is shown.

The distance L5 and the distance L6 are the magnitude of the elastic force of the second spring portion 42, the shape of the second convex portion 48, the shape of the third spring portion 43, the shape and size of the first through hole 15, It is appropriately determined depending on the shape, size, etc. of the second through hole 16 .

Further, as shown in FIG. 9, the second spring portion 42 has a surface that is closer to the wall surface than a surface that is in contact with the rising portion 11 in a direction parallel to the rising portion 11 (±Z direction). An obtuse angle C2 is formed between 11 and the opposite surface closer to the wall surface. Further, as shown in FIG. 9, the third spring portion 43 has a surface closer to the wall surface in contact with the rising portion 11 in a direction parallel to the rising portion 11 (±Z direction), An obtuse angle C3 is formed between 11 and the opposite surface closer to the wall surface. The obtuse angle C2 and the obtuse angle C3 are determined depending on the magnitude of the elastic force of the second spring portion 42 and the third spring portion 43, the shape and size of the first through hole 15 and the second through hole 16, and the like. It can be determined as appropriate.

As described above, in the lighting fixture according to the present embodiment, since the second spring part 42 and the third spring part 43 have elastic force in a direction perpendicular to the upright part 11, the lighting fixture can be attached to the wall surface. Easy to do. In the lighting fixture according to the present embodiment, the mounting member 4 with the lamp 3 mounted thereon can be attached to the fixing member 1 fixed to the wall simply by pushing the mounting member 4 into the fixing member 1 . In other words, in the operation of attaching the mounting member 4 to the fixing member 1 , there is no action that should be performed simultaneously with the action of pushing the mounting member 4 into the fixing member 1 . That is, the lighting fixture according to the present embodiment does not need to perform two or more operations at the same time in the work of attaching the mounting member 4 to the fixing member 1 . Therefore, the lighting fixture according to the present embodiment can easily attach the mounting member 4 to the fixing member 1, so that it can be easily mounted on the wall surface.

Moreover, the lighting fixture according to this embodiment can be more easily attached to the wall surface. The lighting fixture according to the present embodiment has a point H closest to the wall surface on the surface of the second spring portion 42 facing the raised portion 11, and a raised portion of the surface of the third spring portion 43. A distance L6 in the direction perpendicular to the rising portion 11 between the point I closest to the wall surface on the surface facing the rising portion 11 is shorter than the distance L2 between the inner surfaces of the rising portion 11 . Therefore, in the operation of attaching the mounting member 2 to the fixing member 1, the lighting apparatus according to the present embodiment makes it easy to bring the second convex portion 48 into contact with the rising portion 11, and also allows the third convex portion 49 to come into contact with the rising portion. This is because it is easy to abut against 11 .

Furthermore, the lighting fixture according to this embodiment can be more easily attached to the wall surface. The second spring portion 42 of the lighting fixture according to the present embodiment includes a surface closer to the wall surface in contact with the rising portion 11 in a direction parallel to the rising portion 11, and a surface facing the rising portion 11. The angle with the surface closer to the wall surface is an obtuse angle C2. The third spring portion 43 of the lighting fixture according to the present embodiment has a surface closer to the wall surface in contact with the rising portion 11 in a direction parallel to the rising portion 11, and faces the rising portion 11. The obtuse angle C3 is the angle between the two faces that are closer to the wall surface. Therefore, in the operation of attaching the mounting member 4 to the fixing member 1, the lighting fixture according to the present embodiment is fixed after the second spring portion 42 and the third spring portion 43 are brought into contact with the rising portion 11. This is because the mounting member 4 can be easily pushed into the member 1 .

Furthermore, the lighting fixture according to the present embodiment can be more easily attached to a wall surface than the lighting fixture 100 according to the first embodiment of the present invention. This is because the task of hooking the first hook 23 to the second through hole 16 in the task of attaching the lighting fixture 100 according to the first embodiment of the present invention to the wall surface is eliminated.

Moreover, the lighting fixture according to this embodiment can be easily removed from the wall surface.

Therefore, in the lighting fixture according to the present embodiment, since the mounting member 4 can be easily removed from the fixing member 1, it can be easily removed from the wall surface.

Furthermore, the lighting fixture according to the present embodiment can prevent the mounting member 4 from coming off from the fixing member 1 due to the rotation of the lighting fixture 3, as in the lighting fixture 100 according to the first embodiment of the present invention. It goes without saying that we can.

In the present embodiment, the second spring portion 42 and the third spring portion 43 are molded separately from the second connection portion 44 and are connected to the second connection portion 44. The portion 42, the third spring portion 43 and the second spring portion 44 may be integrally molded. Further, the mounting member 4 of the lighting fixture according to the present embodiment does not include the second connecting portion 44, and the second spring portion 42 and the third spring portion 43 are directly connected to the lid portion 21. Also good. Of course, the second spring portion 42 and the second connection portion 44 are formed integrally, but the third spring portion 43 may be formed separately.

In Embodiments 1 and 2 of the present invention, the number of engaging portions and engagement receiving portions is two, respectively. The number is not particularly limited. It is appropriately determined depending on the weight of the lamp 3, the magnitude of the engagement force between the engagement portion and the engagement receiving portion, and the like. I wish I had the power.

The distance in the direction (±Y direction) perpendicular to the rising portion 11 between far points is longer than the distance between the inner surfaces of the rising portion 11 . Therefore, in this embodiment, the fourth spring portion 62 is engaged with the rising portion 11 and the first hook portion 23 is engaged with the rising portion 11 . More specifically, the fourth spring portion 62 and the first hook portion 23 are engaged with the rising portion 11 by utilizing the outward force of the rising portion 11 .

In addition, among the surfaces of the fourth spring portion 62 , the surface facing the raised portion 11 is closest to the wall surface, and the surface of the first hook portion 23 facing the raised portion 11 is closest to the wall surface. The distance in the direction (±Y direction) perpendicular to the rising portion 11 between the closer points is shorter than the distance between the inner surfaces of the rising portion 11 . In the present embodiment, both before and after attaching the mounting member 2 to the fixing member 1, in the surface of the fourth spring portion 62 facing the rising portion 11, the point closest to the wall surface and the first hook The distance in the direction perpendicular to the rising portion 11 (±Y direction) between the point closest to the wall surface on the surface of the portion 23 facing the rising portion 11 is the distance between the inner surfaces of the rising portion 11. shorter than the length of the distance. However, in the present invention, when the mounting member 2 is attached to the fixing member 1, the surface of the fourth spring portion 62 facing the rising portion 11 is closest to the wall surface and the first hook portion The distance in the direction perpendicular to the rising portion 11 (±Y direction) between the point closest to the wall surface on the surface facing the rising portion 11 among the surfaces of 23 is the distance between the inner surfaces of the rising portion 11. It should be shorter than the length of .

In the present embodiment, since the rising portion 11 is cylindrical, the distance between the inner surfaces of the rising portion 11 is the inner diameter of the rising portion 11, and the length is the same everywhere. However, since the rising portion 11 may have a polygonal cylindrical shape, the distance between the inner surfaces of the rising portion 11 may vary depending on the location. In this case, the distance between the inner surfaces of the rising portions 11 is the distance between the inner surfaces of the rising portions 11 in the same cross section in which the distance between the inner surfaces of the rising portions 11 and the distance to be compared are shown.

Further, as shown in FIG. 10, the fourth spring portion 62 has a surface closer to the wall surface of the surfaces in contact with the rising portion 11 in a direction parallel to the rising portion 11 (±Z direction), An obtuse angle C4 is an angle between 11 and the opposite surface closer to the wall surface.

The method for attaching the lighting fixture according to the present embodiment to the wall surface is the same as that for the lighting fixture 100 according to the first embodiment of the present invention. However, the method of removing the lighting fixture according to this embodiment from the wall surface is different from the lighting fixture 100 according to the first embodiment of the present invention.

A method of removing the lighting fixture according to the present embodiment from the wall surface will be described. First, the screw is removed from the second screw hole 17 to release the fixation between the fixing member 1 and the fall prevention fixing portion 25 of the mounting member 6 . Then, the fourth protrusion 68 is pushed inward (in the -Y direction) from the outside of the fixing member 1 . Next, while pushing the fourth convex portion 68 in the −Y direction, the portion of the lid portion 21 where the fourth spring portion 62 is provided is pulled in the −Z direction to tilt the lid portion 21, and the fourth The spring portion 62 is elastically deformed in the -Y direction. After that, the same procedure as the method for removing the lighting fixture 100 according to the first embodiment of the present invention from the wall surface is taken.

As described above, in the lighting fixture according to the present embodiment, the fourth spring portion 62 has an elastic force in a direction perpendicular to the upright portion 11. Therefore, the lighting fixture 100 according to the first embodiment of the present invention Similarly, it is possible to easily attach the luminaire to the wall surface.

Moreover, the lighting fixture according to the present embodiment can be more easily attached to the wall surface of the lighting fixture. A point of the surface of the fourth spring portion 62 facing the raised portion 11 that is closest to the wall surface, and a surface of the first hook portion 23 that faces the raised portion 11 and is closest to the wall surface. is shorter than the distance L2 between the inner surfaces of the rising portion 11 in the direction perpendicular to the rising portion 11 between. Therefore, similarly to the lighting fixture 100 according to the first embodiment of the present invention, in the work of attaching the mounting member 6 to the fixing member 1 , the lighting fixture according to the present embodiment has the fourth convex portion 68 as the raised portion 11 . This is because it is easy to abut on the .

Furthermore, the lighting fixture according to this embodiment can be more easily attached to the wall surface.
