BEST MODE FOR CARRYING OUT THE INVENTION
A wall-mounted device according to an embodiment of the present invention, and a wall-mounted timepiece having the device will be described below with reference to FIG. 1(a) to FIG. 4.
As shown in FIG. 4, a wall-mounted device 1 constitutes a part of a wall-mounted timepiece 20 as an object to be mounted on a wall. The wall-mounted device 1 is for mounting a to-be-mounted-on-wall object on a wall surface or a pillar surface.
As shown in FIGS. 1(a) and 1(b), the wall-mounted device 1 comprises an elastic plate member 10, two boss parts 11, an elastic-plate-member hole 12, a hanging part 13 and two fixing screws 14.
The elastic plate member 10 is a member for preventing the wall-mounted timepiece 20 from falling off. The elastic plate member 10 can be deformed toward the wall-mounted timepiece 20, as shown by a broken line in FIG. 2(b). The elastic plate member 10 is deformed toward the wall-mounted timepiece 20, for example, at the time of mounting and dismounting the wall-mounted timepiece 20 on and from a wall surface or the like. The elastic plate member 10 is made of a plate-like elastic member, such as a stainless thin plate spring material.
The elastic plate member 10 is deformed so that a hook part 30a of an attachment fitting 30 to be described later (see FIGS. 2(a) and 2(b)) is guided to the hanging part 13, thereby opening the elastic-plate-member hole 12. When the hook part 30a is placed at the hanging part 13, the elastic plate member 10 is returned to the original state from the deformed state. At this time, vibration occurs together with generation of a light impact sound.
The elastic plate member 10 is formed in consideration of the material, the thickness, the shape and so forth so as to cause vibration and sound when returning. For example, the elastic plate member 10 has a bent part 10c formed at both side ends entirely or partly, as shown in a horizontal cross section in FIG. 5(a), or has the entire horizontal cross section or a part thereof angled as shown in FIG. 5(b). When pressed and deformed, therefore, a part of the plate member can be warped while keeping the elastic state. When the elastic plate member 10 is returned to the original state from the deformed state, the warping returns to the original state, vibration occurs together with generation of a light impact sound. As shown in FIG. 5(c) showing a portion of abutment of the elastic plate member 10 and the attachment fitting 30, projections 10d, 30d are formed at parts of the elastic plate member 10 and the attachment fitting 30. At the time the elastic plate member 10 returns to the original state from the deformed state, therefore, hooking of the projections is released, and at the same time, vibration occurs together with generation of a light impact sound.
The elastic plate member 10 has a first bent part 10a formed at an upper portion and a pair of second bent parts 10b formed at both lower ends.
The first bent part 10a is bent from the main body at substantially 90 degrees, and extends horizontally in a normal state. The first bent part 10a is disposed at a position to face and abut on the hook part 30a of the attachment fitting 30. With the abutment with the hook part 30a maintained, the first bent part 10a prevents the attachment fitting 30 from coming off the hanging part 13. The end of the first bent part 10a abuts on a casing 21 when the elastic plate member 10 is pressed to a predetermined amount of deformation. This prevents the elastic plate member 10 from being deformed by a predetermined amount of deformation or more to be plastically deformed.
The pair of second bent parts 10b serve to fix the elastic plate member 10 to the casing 21 of the wall-mounted timepiece 20. The pair of second bent parts 10b are constituted by a bent part having an L-shaped cross section. Through holes 101b for insertion of the fixing screws 14 are formed in the pair of second bent parts 10b. 
The fixing screw 14 is put through the through hole 101b of the second bent part 10b, and is screwed into the boss part 11 formed at the casing 21. Accordingly, the elastic plate member 10 is fixed inside the elastic-plate-member hole 12 of the casing 21.
The two boss parts 11 protrude from the front side of the casing 21 of the wall-mounted timepiece 20 as a to-be-mounted-on-wall object to the rear side. A female thread in which the fixing screw 14 is to be screwed is formed in the boss part 11 provided upright at the casing 21. The second bent parts 10b of the elastic plate member 10 are fixed to the two boss parts 11 by screwing of the fixing screws 14 into the female threads, and the two boss parts 11 support the elastic plate member 10.
The elastic-plate-member hole 12 constitutes a recessed part formed on the rear side of the casing 21 of the wall-mounted timepiece 20. As shown in FIG. 2(b), the elastic-plate-member hole 12 is formed to have a sufficient depth, so that the mounting and dismounting of the wall-mounted timepiece 20 can be achieved by deforming the elastic plate member 10.
The hanging part 13 is for hooking the hook part 30a of the attachment fitting 30 (see FIGS. 2(a) and 2(b)), and a cutaway portion 13a formed in the hanging part 13 is for the case of using a wooden screw 40 to be described later (see FIGS. 6(a) and 6(b), and FIG. 7).
The hanging part 13 is formed contiguous to the elastic-plate-member hole 12. An upper wall surface 12a constituting the elastic-plate-member hole 12 is formed in such a way that the width of the elastic-plate-member hole 12 gradually becomes narrower toward the hanging part 13. Therefore, the hook part 30a of the attachment fitting 30 can be guided to the hanging part 13 while abutting on the upper wall surface 12a. 
In case of attaching the wall-mounted timepiece 20 to the attachment fitting 30, the hanging part 13 is positioned topside bottom, so that its position is hard to be confirmed. As the elastic plate member 10 is pressed and deformed inward, however, the upper wall surface 12a of the elastic-plate-member hole 12 appears to guide the hook part 30a to the hanging part 13.
To mount the wall-mounted timepiece 20 on a wall surface or a pillar surface using the wall-mounted device 1, first, the attachment fitting 30 shown in FIGS. 2(a) and 2(b) is fixed to the wall surface or the like by screws.
Then, the hook part 30a of the attachment fitting 30 is hooked on the hanging part 13 of the wall-mounted device 1 while the elastic plate member 10 is deformed inward as shown in FIG. 2(b). Releasing the deformation of the elastic plate member 10 causes vibration together with generation of a light impact sound when the elastic plate member 10 is returned to the original state from the deformed state. With the first bent part 10a of the elastic plate member 10 being in abutment with the hook part 30a of the attachment fitting 30, the wall-mounted timepiece 20 is mounted on the wall surface or the like.
To dismount the wall-mounted timepiece 20 from the wall surface or the like, the elastic plate member 10 is deformed inward first. This creates space enough to detach the hook part 30a of the attachment fitting 30 from the hanging part 13. Then, the casing 21 of the wall-mounted timepiece 20 should be lifted upward while pressing the elastic plate member 10.
Suppose that vibration or impact originated from an earthquake or so acts on the wall-mounted device according to the embodiment in a direction of pushing the wall-mounted timepiece 20 upward. Even in such a case, the first bent part 10a of the elastic plate member 10 holds the hook part 30a of the attachment fitting 30, thereby preventing the hook part 30a from coming off the hanging part 13. This is because when force acts in the direction of pushing the wall-mounted timepiece 20 upward, the elastic plate member 10 receives the force in the in-plane direction in which the elastic plate member 10 formed has substantial rigidity.
In the wall-mounted device according to the embodiment, the hook part 30a of the attachment fitting 30 is guided to an adequate position, and vibration occurs together with generation of a light impact sound when the elastic plate member 10 is returned to the original state from the deformed state. This makes it possible to easily confirm the adequate mounting of the wall-mounted timepiece 20 on a wall surface or the like, and thus prevent the wall-mounted timepiece 20 from falling off due to inadequate mounting.
Further, in the wall-mounted device according to the embodiment, the wall-mounted timepiece 20 can be dismounted easily by pressing the elastic plate member 10 with a finger to lift up the casing 21 of the wall-mounted timepiece 20. On the other hand, the dismounting scheme, which is not easily surmised, can serve to prevent theft or so of the wall-mounted timepiece 20.
In addition, in the wall-mounted device according to the embodiment, a stainless plate spring material or the like is used for the elastic plate member 10. This can realize a low-cost and highly reliable structure.
In the wall-mounted device according to the embodiment, the boss part 11 has only to be added without changing the existing shape of the elastic-plate-member hole 12. In addition, the existing attachment fitting 30 or the like can be used. This eliminates the need to use a fitting or a screw which has a special shape and structure for hooking, and can thus suppress the cost.
It is possible to easily confirm the adequate mounting of the wall-mounted timepiece according to the embodiment on a wall surface or the like. This can prevent inadequate-mounting originated fall-off of the wall-mounted timepiece. Further, because the dismounting scheme is not easily surmised, theft of the wall-mounted timepiece can be prevented. As a result, a low-cost and highly reliable structure can be realized.
The present invention is not limited to the foregoing embodiment, and can be modified and applied in various forms. While the foregoing description of the embodiment has been given of the example of using the attachment fitting 30, for example, a wooden screw 40 may be used instead of the attachment fitting 30 as shown in FIGS. 6(a) and (b) and FIG. 7.
While the foregoing description of the embodiment has been given of the example where a to-be-mounted-on-wall object is the wall-mounted timepiece 20, the to-be-mounted-on-wall object may be a frame or an electrical apparatus, such as a telephone set or an electric fan.
In addition, the foregoing description of the embodiment has been given of the example where the elastic plate member 10 has the first bent part 10a formed thereat. However, an elastic member 50 formed by a simple flat plate may be used as shown in FIG. 8. The elastic member 50 has its lower portion fixed to the casing 21 as fixing screws 51 are screwed into screw holes 21a formed in the casing 21.
A hole may be bored in an end of the elastic plate member 10 in the embodiment, and a wire or TY-RAP or the like may be put through the hole to achieve double effects of fall-off prevention and dismount prevention.
As shown in FIG. 9, an attachable/detachable attaching/detaching member, such as a surface fastener (MAGIC TAPE (registered trademark)) 22, may be adhered to the casing 21 and a wall surface or a pillar surface which faces and abuts on the casing 21.
This can prevent a change in posture when light vibration is applied to a to-be-mounted-on-wall object, without affecting the mounting or dismounting. As the present invention can surely mount a to-be-mounted-on-wall object, the invention can take such a structure.
This application is based on Japanese Patent Application No. 2006-114351 filed on Apr. 18, 2006, and the specification, claims, and drawings thereof are incorporated herein by reference in its entirety.
