  The present invention has been made in order to solve the above-described problems of the prior art, and the purpose of the present invention is to facilitate installation and to enhance the appearance of the wall surface when the installation object is mounted with the back surface facing the wall surface. It is an object of the present invention to provide a wall surface fixture suitable for concealing and mounting an attachment, and an installation including the same.

  The wall surface fixture of the present invention is a wall surface fixture that is mounted with the back surface of the casing of the installation object facing the wall surface, and the first screw shaft protruding by screwing into the back surface of the housing passes through the first surface. A base having a circular hole and a second circular hole through which a shaft portion of a second screw projectingly engaged with the wall surface passes, the base being part of the base and the head of the second screw being a housing. Wall mounting work where the entire base and the head of the second screw are hidden behind the housing and are not exposed without touching the housing during the wall mounting work of the installation that is exposed without being hidden behind the body Later, it has a latching part that abuts the latching part of the casing and latches the installation object.

  Preferably, the locking portion of the wall surface fixture of the present invention is provided with a second screw that passes through the second circular hole together with the wall surface fixture so as not to substantially change a predetermined posture of the installation object with respect to the wall surface during the wall surface attachment operation. When rotating as a central axis, it is provided at a predetermined position that abuts on a locking portion of the installation object and suppresses the rotation of the installation object.

  Preferably, the wall surface fixture of the present invention includes a first plane portion in which the first circular hole is formed, a second plane portion in which the second circular hole is formed substantially parallel to the first plane portion, and the first plane. And a connecting portion that connects the second flat surface portion, and the connecting portion and the locking portion are provided in a space defined by the first flat surface portion and the second flat surface portion.

  Preferably, in the wall surface fixture of the present invention, the first flat surface portion further includes a third circular hole through which a shaft portion of a third screw projectingly engaged with the rear surface of the housing passes, The plane portion further has a dharma hole through which the head of the second screw passes.

  Preferably, in the wall surface fixture of the present invention, the first circular hole and / or the second circular hole are formed as a part of a dharma hole through which a head of the first screw and / or the second screw passes. Yes.

  In addition, the installation of the present invention includes the wall surface fixture described above, a housing having a locking portion on the back surface, a threaded engagement with the back surface of the housing, and the shaft portion having the first circular hole of the wall surface mounting device. A first screw passing therethrough.

  In addition, the installation object of the present invention has the first screw so that the second screw is positioned at a substantially central position in the left-right direction of the housing after the wall surface mounting operation in which the wall surface attachment tool is not exposed behind the installation object. It protrudes into a predetermined position on the back of the housing.

  The operation of the present invention will be described below.

  The wall surface fixture of the present invention is a wall surface fixture that is mounted so that the back surface of a casing (cabinet) of an installation such as a speaker faces the wall surface. Moreover, the installation object of this invention is provided with this wall surface fixture and the housing | casing which has a latching | locking part in a back surface. The base of the wall fixture passes through the first circular hole through which the shaft portion of the first screw protruding by screwing to the rear surface of the housing and the shaft portion of the second screw protruding by screwing into the wall surface. A second circular hole. Furthermore, the wall surface fixture is not in contact with the casing during the wall mounting operation of the installation object in which a part of the base and the head of the second screw are exposed without being hidden behind the casing. And after the wall surface mounting operation in which the head of the second screw is hidden behind the housing and is not exposed, it has a locking portion that contacts the locking portion of the housing and locks the installation object.

  That is, the locking portion of the wall surface fixture does not contact the housing during the wall surface mounting operation of the installation object, but contacts the locking portion on the back side of the housing after the wall surface mounting operation, Lock. Therefore, when the installation object is mounted with its back face facing the wall surface, part of the base of the wall surface mounting tool and the head of the second screw are exposed without being hidden behind the housing during the mounting operation. In addition, since the entire wall surface fixture and the head of the second screw are hidden behind the housing and are not exposed after the wall surface mounting operation, the installation object can be attached to the wall surface with a good appearance.

  Specifically, the locking portion of the wall surface fixture is centered on the second screw that passes through the second circular hole together with the wall surface attachment so that the predetermined posture of the installation object is not substantially changed with respect to the wall surface during the wall surface attachment operation. When rotating as a shaft, it is provided at a predetermined position that abuts against a locking portion of the installation object and suppresses the rotation of the installation object. That is, the locking portion of the wall surface fixture is a position that contacts the locking portion of the installation object when the wall surface fixture is rotated with the second screw passing through the second circular hole as the central axis of rotation. The installation object is provided at a position where the installation object is attached to the wall surface in a posture of a predetermined angle. Therefore, when the installation object is mounted with the back surface facing the wall surface, the operator does not substantially change the predetermined posture after the installation object and the wall surface mounting tool are mounted on the wall with the first screw and the second screw. If the installation object is lifted and turned around the exposed second screw as a central axis, all of the wall fixture that was partially exposed will be hidden behind the housing together with the second screw. Since the locking portion of the wall surface fixture comes into contact with the locking portion of the housing to lock the installation object, the installation object can be attached to the wall surface at a predetermined angle. In addition, since the screw heads of the screws constituting the fixture on the wall surface are unlikely to be detached from the fixture, there is less risk of the fixture falling due to contact with the fixture or shaking due to an earthquake.

  The wall surface fixture includes a first plane part in which the first circular hole is formed, a second plane part in which the second circular hole is formed substantially parallel to the first plane part, and the first plane part and the second plane part. A shape having a connecting portion for connecting to each other is preferable. The wall surface mounting tool only needs to be provided with a connecting portion and a locking portion in a space defined by the first flat surface portion and the second flat surface portion, and the head of the first screw and the second screw in the space. Can hold the head. Therefore, without interfering with the head of the first screw or the second screw, the installation object and the wall mounting tool are arranged with the second screw as the central axis, and the locking part of the wall mounting tool and the locking part of the installation tool are It can be rotated until it is locked.

  In addition, the wall surface fixture may further include a third circular hole through which the first flat portion passes through a shaft portion of a third screw that protrudes by being screwed to the back surface of the housing. However, it may further have a dharma hole through which the head of the second screw passes. In this case, since the wall surface fixture is attached at two points of the first screw and the third screw, it is not suitable for rotating around the second screw screwed to the wall surface, There exists an advantage which can be used also as a wall surface fixture of the conventional fixing method used so that it may hide behind the housing | casing of an installation thing.

  Further, the wall surface fixture may form the first circular hole and / or the second circular hole as a part of a dharma hole through which the head of the first screw and / or the second screw passes. If the first circular hole and / or the second circular hole is made into a dharma hole, the wall surface fixture is attached to and detached from the first screw screwed to the back surface of the installation object or the second screw screwed to the wall surface. This has the advantage of facilitating wall surface mounting work.

  In addition, the installation object is the above-mentioned wall surface fixture, a housing having a locking portion on the back surface, and a projecting threadedly engaged with the back surface of the housing so that the shaft portion passes through the first circular hole of the wall surface attachment device. 1 screw may be provided. After the wall mounting operation in which the wall mounting tool is hidden behind the installation object and is not exposed, the first screw is screwed into a predetermined position on the rear surface of the housing so that the second screw is positioned at a substantially central position in the left-right direction of the housing. What is necessary is just to make it protrude. Since the wall surface fixture and the second screw support a substantially central position in the left-right direction of the housing close to the center of gravity of the installation object, the installation object can be attached to the wall surface so as not to tilt in the left-right direction.

  The wall surface fixture of the present invention is easy to mount and can be attached while concealing the wall surface fixture when the installation object is mounted with the back surface of the installation object facing the wall surface.

Example 1 It is a figure explaining the other bracket 10 of this invention. (Example 2) It is a figure explaining the other bracket 10 of this invention. (Example 3)

  Hereinafter, although the wall surface fixture by the preferable embodiment of this invention and the installation containing it are demonstrated, this invention is not limited to these embodiment.

  FIG. 1 is a diagram illustrating a speaker system 1 according to a preferred embodiment as an installation of the present invention. Specifically, FIG. 1 is a perspective view of the speaker system 1 that is attached to the wall surface 4 using a bracket 10 that is a wall surface attachment tool, and includes a schematic diagram that shows the relative position of the bracket 10. In this schematic diagram, a wall surface 4 is formed on the XZ plane shown in the figure, the Z direction is a vertical direction in which gravity acts, and the Y direction is a horizontal direction perpendicular to the wall surface 4. In FIG. 1, a part of the configuration of the speaker system 1 that is not necessary for explanation is omitted.

  The speaker system 1 of the present embodiment includes a speaker unit 2 (not shown) and a cabinet 3 to which the speaker unit 2 is attached. The speaker unit 2 (not shown) is attached to the front surface 3f of the cabinet 3, and when a sound signal current is supplied, the speaker diaphragm oscillates in the front-rear direction to emit sound waves. In the present embodiment, the speaker unit 2 is not shown, and the cabinet 3 is provided with a circular hole 2a in which a tweeter for high-frequency range reproduction is attached and a circular hole 2b in which a woofer for middle-low range reproduction is attached. It shows how it is done. The substantially rectangular parallelepiped cabinet 3 separates the front and rear spaces of the speaker diaphragm and defines the acoustic capacity therein. For example, the cabinet 3 formed of a wood material or resin is configured by connecting a front portion including a front surface 3f and a rear portion including a back surface 3r.

  FIG. 1A is a diagram showing a state during the operation of attaching the speaker system 1 to the wall surface, and FIG. 1B is a diagram showing a state after the operation of attaching the speaker system 1 to the wall surface. The cabinet 3 is attached using a bracket 10, screws 5 (not shown in FIG. 1), and screws 6 with its planar back surface 3 r facing a vertical planar wall surface 4. As shown in FIG. 1A, during the mounting operation, a part of the bracket 10 and the head of the screw 6 are exposed without being hidden behind the cabinet 3, but are shown in FIG. Thus, after the mounting operation, the entire bracket 10 and the head of the screw 6 are hidden behind the cabinet 3 and are not exposed.

  FIG. 2 is a diagram for explaining the operation of the bracket 10 in the work of attaching the speaker system 1 to the wall surface 4. Specifically, FIG. 2A to FIG. 2D are partial perspective views of the speaker system 1 as viewed from the back surface 3r side through the wall surface 4, respectively. ) To FIG. 2 (c) sequentially show the state during the attachment work, and FIG. 2 (d) shows the state after the attachment work. FIG. 3 is a diagram illustrating the bracket 10 and is an enlarged perspective view of the state of FIG.

  The bracket 10 is a member obtained by cutting and bending a metal plate by pressing. The bracket 10 includes a flat portion 11 in which a circular hole through which a shaft portion of the screw 5 screwed to the rear surface 3r of the cabinet 3 is inserted, and a shaft of the screw 6 screwed to the wall surface 4 substantially parallel to the flat portion 11. A flat portion 12 in which a circular hole is inserted, and a connecting portion 13 that connects the flat portion 11 and the flat portion 12. The locking part 14 is formed by bending a part extending from the flat part 12 toward the flat part 11. Therefore, the connecting portion 13 and the locking portion 14 are provided in a space defined by a plane including the plane portion 11 and a plane including the plane portion 12 that are in a substantially parallel relationship with each other.

  Further, since the rear surface 3r of the cabinet 3 is provided at a position one step deeper from the rear end of the top surface 3t of the cabinet, the engagement portion 14 of the bracket 10 abuts around the rear surface 3r of the cabinet 3. A stop 3b is formed. In this embodiment, the locking portion 3b is notched at the top surface 3t, and a notch 3k through which a part of the rotating bracket 10 passes is defined as will be described later. In addition, the latching | locking part 3b should just be provided in the place near the top | upper surface 3t of the back surface 3r of the cabinet 3, and the notch part 3k does not necessarily need to be provided.

  Hereinafter, an operation of attaching the speaker system 1 to the wall surface 4 using the bracket 10 by an operator (not shown) will be described in order. The operator first attaches the bracket 10 by screwing the screw 5 into a predetermined position on the back surface 3r of the cabinet 3. At this time, since it is not necessary to work by bringing the back surface 3r of the cabinet 3 and the wall surface 4 close to each other, the operator can easily insert the shaft portion of the screw 5 through the circular hole of one flat surface portion 11 of the bracket 10. The bracket 10 can be attached to the bracket. The operator lifts the other flat portion 12 of the bracket 10 so as to protrude from the top surface 3t of the cabinet 3, and exposes the cabinet 3 when viewed from the front.

  Next, the worker lifts the speaker system 1 along the wall 4 and temporarily places the speaker system 1 at a predetermined position. As shown in FIG. 1A or FIG. Attach to face 4 At this time, since the shaft portion of the screw 6 can be inserted into the circular hole of the flat portion 12 of the bracket 10 from the front surface 3f side of the cabinet 3, the cabinet 3 and the bracket 10 can be easily attached to the wall surface 4. Can do. In this state, as shown in FIG. 1A, the bracket 10 hangs from the wall 4 at an angle such that the screw 6 is on the upper side and the screw 5 is on the lower side. I can release my hand. Further, during the mounting operation, a part of the bracket 10 and the head of the screw 6 are exposed without being hidden behind the cabinet 3 as shown in the figure.

  Next, the worker rotates the speaker system 1 clockwise about the screw 6 along the wall 4. That is, the speaker system 1 may be lifted so as not to change the predetermined posture as shown in the figure, and may be rotated around the exposed screw 6 as the central axis. Then, as illustrated in FIGS. 2B and 2C, when the cabinet 3 is rotated about 90 degrees or more, the heads of the bracket 10 and the screw 6 are hidden behind the cabinet 3. Since the bracket 10 and the head of the screw 6 pass through the notch 3k on the back surface 3r of the cabinet 3, the operator can smoothly rotate the cabinet 3.

  Further, when the operator rotates the speaker system 1 clockwise about the screw 6 along the wall 4, the cabinet 3 is about 135 as shown in FIGS. 1 (b) and 2 (d). Since the locking portion 14 of the bracket 10 and the locking portion 3b behind the cabinet 3 come into contact with each other, the rotation stops. At this time, the locking portion 14 of the bracket 10 attached to the back surface 3r of the cabinet 3 by the screw 5 is located near the screw 6 screwed to the wall surface 4 as shown in FIG. The locking portion 3b that is close to the center position in the left-right direction is supported from below. Therefore, after the attachment work, the speaker system 1 can be attached to the wall surface 4 with a part of the bracket 10 and the head of the screw 6 hidden behind the cabinet 3 and not exposed. Since the screw 6 that is screwed into the wall surface 4 is positioned at a substantially central position in the left-right direction of the cabinet 3, the speaker system 1 is attached to the wall surface 4 without being inclined in the left-right direction.

  The locking portion 14 of the bracket 10 is not limited to the case of the above embodiment, but does not contact the cabinet 3 during the wall surface mounting operation of the speaker system 1, and after the wall surface mounting operation, the rear surface 3r of the cabinet 3. What is necessary is just to contact | abut to the latching | locking part 3b provided in the place of the side, and latch the rotation of the cabinet 3. When the rear surface 3r of the cabinet 3 is mounted to face the wall surface 4, the bracket 10 and the head of the screw 6 are exposed without being hidden behind the housing during the mounting operation, so that the mounting is facilitated. In addition, after the wall mounting operation, the entire bracket 10 and the head of the screw 6 are hidden behind the cabinet 3 and are not exposed. Therefore, the speaker system 1 can be attached to the wall surface 4 with good appearance.

  The bracket 10 is provided with a connecting portion 13 and a locking portion 14 in a space defined by the flat surface portion 11 and the flat surface portion 12, and accommodates the head portion of the screw 5 and the head portion of the screw 6 protruding into this space. be able to. Therefore, the speaker system 1 and the bracket 10 are locked by the locking portion 14 of the bracket 10 and the locking portion 3b of the cabinet 3 around the screw 6 without interfering with the head of the screw 5 or 6. Can be rotated. Further, since the screw heads of the screws 5 and 6 are not easily detached from the bracket 10, the possibility of the speaker system 1 falling due to contact with the cabinet 3 or shaking due to an earthquake can be reduced.

  FIG. 4 is a diagram illustrating a bracket 10 according to another preferred embodiment of the present invention. Specifically, FIG. 4 is an enlarged perspective view of a state in which the speaker system 1 with the bracket 10 hidden behind the cabinet 3 is installed on the wall surface 4 as in FIG. 3. In FIG. 4, the screw 5 or 6 is not illustrated, and the circular hole 15 through which the shaft portion of the screw 5 provided in the flat portion 11 of the bracket 10 is inserted and the shaft of the screw 6 provided in the flat portion 12 are illustrated. A circular hole 16 through which the part is inserted is shown.

  The bracket 10 is a member obtained by cutting and bending a metal plate by press work, as in the case of the previous embodiment. The bracket 10 has a connecting portion 13 that connects the flat portion 11 and the flat portion 12, and the locking portion 14 that comes into contact with the locking portion 3 b provided on the back surface 3 r side of the cabinet 3 is connected to the flat portion 12. It is formed so that this connection part 13 may serve. That is, the connecting portion 13 and the locking portion 14 are provided in a space defined by a plane including the plane portion 11 and a plane including the plane portion 12 that are substantially parallel to each other. Further, the length dimension of the connecting portion 13 of the bracket 10 substantially matches the dimension in which the locking portion 3b protrudes from the back surface 3r of the cabinet 3.

  In the case of the present embodiment, when the cabinet 3 is rotated about 90 degrees or more, the bracket 10 and the head of the screw 6 are hidden behind the cabinet 3. The rear surface 3r of the cabinet 3 is not provided with the notch 3k as in the previous embodiment, but an insert nut into which the screw 5 is screwed is provided, and the rear surface 3r side of the cabinet 3 is adjusted in accordance with the rotation operation. If the screw 5 and the bracket 10 are moved, the operator can smoothly rotate the cabinet 3 so that the screw head of the screw 6 does not interfere with the protruding portion on the side surface side of the cabinet 3.

  Further, if the screw 6 (not shown in FIG. 4) is a low-head screw with a low overall screw head height, the screw head of the screw 6 does not interfere with the cabinet 3 and the locking portion 14 of the bracket 10 and the cabinet 3 It can be rotated about 180 degrees until the locking portion 3b is locked. Since the screw 6 that is screwed into the wall surface 4 is positioned at a substantially central position in the left-right direction of the cabinet 3, the speaker system 1 is attached to the wall surface 4 without being inclined in the left-right direction.

  In addition, the bracket 10 may form the circular hole 15 and / or the circular hole 16 as a part of a dharma hole through which the head of the screw 5 and / or the screw 6 passes. If the circular hole 15 and / or the circular hole 16 is a dharma hole, the bracket 10 can be easily attached to and detached from the screw 5 screwed to the back surface 3r of the cabinet 3 or the screw 6 screwed to the wall surface 4. There is an advantage that the work of attaching to the wall surface 4 is further facilitated.

  FIG. 5 is a diagram for explaining the operation of the bracket 10 according to another preferred embodiment of the present invention in the operation of attaching the speaker system 1 to the wall surface 4. Specifically, FIG. 5A and FIG. 5B are partial perspective views of the speaker system 1 as viewed from the back surface 3r side through the wall surface 4, respectively. ) Shows a state during the attachment work, and FIG. 5B shows a state after the attachment work.

  The bracket 10 of the present embodiment is a member obtained by cutting and bending a metal plate by pressing, as in the case of the previous embodiment. The bracket 10 includes the connecting portion 13 that connects the flat portion 11 and the flat portion 12 and the locking portion 14 that comes into contact with the locking portion 3b provided on the back surface 3r side of the cabinet 3 in the previous embodiment. Common to the case of. That is, the connecting portion 13 and the locking portion 14 are provided in a space defined by a plane including the plane portion 11 and a plane including the plane portion 12 that are substantially parallel to each other.

  The length dimension of the connecting portion 13 of the bracket 10 is set longer than the dimension in which the locking portion 3b protrudes from the back surface 3r of the cabinet 3. Therefore, the screw 6 can be rotated until the locking portion 14 of the bracket 10 and the locking portion 3 b of the cabinet 3 are locked without interfering with the cabinet 3. An operator can attach the speaker system 1 to the wall surface 4 in a state where a part of the bracket 10 and the head of the screw 6 are hidden behind the cabinet 3 and are not exposed after the installation work. Since the screw 6 that is screwed into the wall surface 4 is positioned at a substantially central position in the left-right direction of the cabinet 3, the speaker system 1 is attached to the wall surface 4 without being inclined in the left-right direction.

  This bracket 10 has a circular hole 17 through which a shaft portion of another screw (not shown) passes in the flat surface portion 11 and a dharma hole 18 in the flat surface portion 12. This is different from the embodiment. Since the bracket 10 has the circular hole 17 and the dharma hole 18, the bracket 10 is not rotated at the time of work as described above, but also as a bracket of a conventional fixing method used so as to be hidden behind the speaker system 1. Can be used. In the state of FIG. 5B, the bracket 10 is attached to the back surface 3r of the cabinet 3 at two points by a screw 5 that passes through the circular hole 15 (not shown) and a screw that passes through the circular hole 17 (not shown). When attached, the bracket 10 does not rotate.

  Therefore, if the screw 6 to be screwed into the wall surface 4 does not pass through the circular hole 16 of the bracket 10 as shown in the drawing, but passes through the Dharma hole 18, the bracket 10 is hidden behind the cabinet 3. Can be used with the conventional fixing method that looks good after work. That is, even when the position of the screw 6 on the wall surface 4 side is not visible to the operator from the front side during the attachment operation, the operator can easily attach the speaker system 1 to the wall surface 4 and There is an advantage that it is possible to work by selecting one of the methods which are judged to be good after work, and the choices are increased.

  In addition, in the bracket 10 of the said Example, although all cut | disconnected and bent the metal plate by the press work and provided the connection part 13 which connects the plane parts 11 and 12 located in a different plane, the bracket 10 The flat surface parts 11 and 12 may be a member provided with a planar substrate included in one plane. Of course, the bracket 10 may be formed using a material other than a metal plate such as resin. The bracket 10 includes a circular hole 15 through which the shaft portion of the screw 5 protruding by screwing with the back surface 3r of the cabinet 3 passes, and a circular hole 16 through which the shaft portion of the screw 6 protruding by screwing with the wall surface 4 passes. After the wall mounting operation, it is only necessary to have the locking portion 14 that contacts and locks the locking portion 3b of the cabinet 3. During the mounting work on the wall surface 4, a part of the bracket 10 and the head of the screw 6 are not hidden behind the cabinet 3, and the work is easy. A mounting method in which the head of 6 is hidden behind the cabinet 3 and is not exposed can be realized.
