Description

  The present invention relates to a wall clock, and more particularly, to a wall clock that is hooked by a hook on a hook that protrudes from a mounting wall so that the back surface of the clock frame is close to the wall.

  A wall clock that detects whether or not a hook projecting from a mounting wall surface is engaged with a hook of a wall clock is known (for example, Patent Document 1).

However, even if the hook is hooked on the wall of the wall clock, if the back of the clock frame is separated from the mounting wall surface, the wall clock is locked and supported by the hook in an unstable manner. There is a risk that the wall clock will tilt or come off the bracket.
Japanese Utility Model No. 56-91991 microfilm (Japanese Utility Model Publication No. 57-203393)

  The present invention has been made in view of the above points, and an object of the present invention is to provide a wall clock that can sense whether or not the back surface of the clock frame is in a predetermined position with respect to the mounting wall surface. is there.

  In order to achieve the above object, the wall clock of the present invention is a wall clock that is hooked to a hook that protrudes from the mounting wall surface so that the back surface of the clock frame is close to the mounting wall surface. However, when the rear surface of the watch frame body is in the proximity area close to the mounting wall surface, the reference proximity position and the back surface of the watch frame body are separated from the mounting wall surface. And a latching state detecting means mounted on the hook body main body so as to be movable between a spacing warning position taken when in the separated area.

  In the wall clock of the present invention, “the reference proximity position taken when the back surface of the timepiece frame is in the proximity region close to the mounting wall surface and the separation warning position taken when the back surface of the timepiece frame is in the separation region separated from the mounting wall surface” The hook state detecting means mounted on the main body of the hook portion is provided so that it can be moved between the watch frame and whether or not the back surface of the watch frame is in the proximity region close to the mounting wall surface. Since it can be detected by the sensing means, the clock frame body of the wall clock is separated from the mounting wall surface due to an earthquake or the like, or the clock frame body of the wall clock is gradually separated from the mounting wall surface due to vibrations in the child room, etc. When the hook is gradually detached from the mounting wall and the clock frame of the wall clock is gradually separated from the mounting wall, the latching state sensing means takes the separation warning position, so the position of the latching sensing means is detected. The wall clock And is locked state is released, it is possible to avoid in advance a possibility to risk falling wall clock occurs. Not only when the wall clock gradually moves away from the mounting wall after being hooked, but also when the wall clock is accidentally hooked away from the mounting wall when hooking on the hook. Since the sensing means adopts the separation warning position, it can be easily sensed that there is a possibility of falling off the hooking tool due to a poor latching state of the wall clock, and it is possible to prevent a fall accident or the like.

  In the wall clock of the present invention, typically, the hook main body has an engagement recess to be engaged with the hook, and the hook state detection means has the clock frame in the proximity region and the hook. Between the normal engagement position taken when the tool is engaged with the engagement concave part of the hanging part main body part and the poor engagement position taken when the hooking tool is outside the engagement concave part of the hanging part main body part It is movably mounted on the hanging body.

  In this case, not only whether or not the back surface of the watch frame is in the proximity region close to the mounting wall surface, but also whether or not the hook is hooked in the engaging recess of the hook body of the watch frame is detected by the latching state Can be sensed by. Accordingly, whether or not the clock frame of the wall clock is set at a predetermined mounted position with respect to the mounting wall surface and the hooking tool on the wall surface, whether or not the latching state detecting means is at the normal engagement position. Can be determined. Here, the fact that the wall clock is at a predetermined mounted position or a predetermined hooked position corresponds to the hook state detection means being at the normal engagement position.

  The wall clock of the present invention typically has a notifying means for notifying whether or not the hook state detecting means is in the normal engagement position.

  In this case, it is possible to know whether or not the latching state sensing means is in the reference proximity position and the normal engagement position by the notification information by the notification means, and the wall clock is attached to the mounting wall surface by the notification information by the notification means. It is possible to know whether or not the hook is set at a predetermined mounting position.

  Here, there are two types of notification signals by the notification means, such as light signals such as light emission or lighting and blinking, acoustic signals such as alarms and melodies, and other signals that can be sensed by human senses (for example, smell). A combination of the above signals may be used. The notification means typically issues a notification signal as a warning when the wall clock is not set at a predetermined mounted position. However, if desired, on the contrary, when the wall clock is set at a predetermined mounted position, a signal to that effect may be issued.

  When the notification means is composed of light emitting means (for example, LED or lamp), the light emitting means is behind the dial so that light can be emitted forward through a window or opening formed in the dial, for example. Placed in. However, as long as the user can visually recognize, instead, for example, light may be emitted forward through a window part or an opening part formed in the clock frame body on the outer periphery of the dial. When the wall clock is a radio timepiece whose display time can be corrected based on a standard radio signal including time information, the light emitting means may be shared with the light emitting means for confirming reception of radio waves.

  In the wall clock of the present invention, for example, there is provided a rotation / translation mechanism including a pair of elongated holes that are long in the vertical direction and a pair of protrusions that are arranged substantially along a straight line and are loosely fitted in the corresponding elongated holes. The hanging portion main body is provided with one of the elongated hole and the protrusion of the rotation / translation mechanism in the vicinity of the back surface of the watch frame body, and the latching state detecting means is the elongated hole of the rotation / translation mechanism. And the other of the protrusions on one end in the vertical direction, and can be moved up and down with respect to the main part of the hook in the vicinity of the back of the watch frame body, and the other end in the vertical direction of the latching state sensing means Is pivotable about the central axis of the projection between a projecting pivot position projecting from the back surface of the watch frame and a non-projecting position substantially extending along the rear surface, and the latch section is in a latched state. An elastic bias in a direction to bias the other end portion to the projecting rotation position with respect to the sensing means. To exert a force, having elastic biasing means provided between the hook main body and the hooking state sensing means.

  In this case, it can be detected with a relatively simple structure whether or not the wall clock is set at a predetermined mounted position with respect to the mounting wall surface and the hook on the wall surface. In this case, when the back face of the watch frame is located close to the mounting wall surface, the protrusion of the other end side portion of the latching state detecting means is attached even under the action of the elastic biasing force by the elastic biasing means. Since it is restricted by the wall surface, the latching state sensing means takes a non-projecting position.

  When the rotation / translation mechanism as described above is provided in the wall clock according to the present invention, the wall clock according to the present invention typically has the other end side portion of the hook state detection means in the non-projecting position and the hook. When the state sensing means takes the upper end position with respect to the hanging portion main body, it has a notifying means whose operating state is changed by the hanging state sensing means.

  Also in this case, it is possible to know whether or not the latching state detection means is in the normal engagement position by the notification information by the notification means, and the wall clock is hooked to the mounting wall surface and the wall surface is caught by the notification information by the notification means. It is possible to know whether or not a predetermined attached position is set with respect to the tool.

  Therefore, the wall clock of the present invention is typically a wall clock that is hooked by a hook on a hook that protrudes from the mounting wall such that the back surface of the clock frame is close to the mounting wall. Includes a pivot / translation mechanism including a pair of elongated holes that are long in the vertical direction and a pair of protrusions that are arranged substantially along a straight line and are loosely fitted in the corresponding elongated holes, and the back surface of the watch frame body. A hanging part main body part formed on the side and provided with one of the elongated hole and the protruding part of the rotating / translating mechanism in the vicinity of the back surface of the watch frame body, and of the elongated hole and protruding part of the rotating / translating mechanism Is provided at one end in the vertical direction, and is supported by the hook main body so as to be movable up and down with respect to the hook main body near the back of the watch frame, and the other end in the vertical direction is the watch frame. Between the projecting rotation position projecting from the back of the body and the non-projecting position substantially along the back surface. A latching state detecting means supported by the hanging portion main body so as to be rotatable around a mandrel axis, and an elastic bias in a direction for biasing the other end side portion to the protruding rotation position with respect to the latching state detecting means. In order to exert a force, an elastic biasing means provided between the hanging portion main body and the hanging state sensing means, and the other end side portion of the hanging state sensing means take a non-projecting position and the hanging state sensing means Has a notifying means whose operating state is changed by the hook state detecting means when the upper end position is taken with respect to the hook main body.

  Next, a preferred embodiment of the present invention will be described based on a preferred example shown in the accompanying drawings.

  As shown in a sectional view in FIG. 1, a wall clock 1 according to a preferred embodiment of the present invention includes a machine mounting plate 2, a rear frame 4 attached to the back side of the machine mounting plate 2 and supporting a movement 3, and a machine And a front frame 5 attached to the front side of the attachment plate 2. A dial 6 is disposed and fixed between the machine mounting plate 2 and the front frame 5, and penetrates the machine mounting plate 2 and the dial 6 out of the shaft portion protruding forward A2 in the front-rear direction A from the movement 3. A time display hand 7 such as an hour hand, a minute hand and a second hand is attached to the protruding tip. Glass 9 is attached to the front frame 5 by glass fixing means 8. The machine mounting plate 2 has an opening 2a in the form of a through hole. The dial 6 also has an opening 6 a at the same position as the opening 2 a of the machine mounting plate 2. The opening 6a may be a simple through hole or a window made of a light transmissive material.

  In this example, the clock frame body 10 includes the rear frame 4 and the front frame 5, and the back surface 10 a that is close to the wall surface K 1 of the mounting wall portion K of the clock frame body 10 is from the back surface of the rear frame 4. Become. In this specification, the clock frame 10 refers to a portion of the wall clock 1 where the back surface 10a is hooked in close proximity to the wall surface K1 of the mounting wall K, and the movement 3, dial 6 and time display. Any other arrangement may be used for the arrangement, accommodation, and support of the needle 7 and the glass 9.

  The rear frame 4 is in contact with the back side of the machine mounting plate 2 and extends along the machine mounting plate 2 in the thickness direction A of the timepiece 1 with respect to the front plate 12. It includes a thickness direction extending plate-like portion 13 that extends to form a receiving area for various timepiece components including the movement 3, and a back side or rear side plate-like portion 14 that defines the back side of the timepiece 1.

  On the upper part of the rear frame 4, a main body 20 of a latching mechanism 15 is formed as a hook for hooking the wall clock 1 to a hook or hook 60 of the mounting wall K. The hanging part main body part or the latching mechanism main body part 20 forms part of the thickness direction extending plate-like part 13 and forms a depth projecting in the thickness direction A of the timepiece 1 in the thickness direction A of the timepiece 1 on the back side in the A1 direction. A plate-like portion 21, a part of the rear-side plate-like portion 14, a latching recess-forming plate-like portion 22 extending in the vertical direction from the extending end of the depth-forming plate-like portion 21, and a part of the front-side plate-like portion 12 And a substrate portion 23 that functions as a spring receiver described later. The latching recessed portion forming plate-like portion 22 is a plate-like portion located on the rearmost side (A1 direction) among the plate-like portions 14a, 14b, 14c,... Constituting the rear plate-like portion 14 of the rear frame 4. 14a, and can approach or abut against the surface K1 of the structure wall K on which the wall clock 1 is to be hung. In this example, the back surface of the plate-like portion 14 a is the back surface 10 a of the watch frame body 10. As shown in FIG. 2 and FIG. 3, the latching recess forming plate-like portion 22 of the hanging portion 20 is an engagement recess composed of a trapezoidal recess 24 and a vertical recess 25 that is long in the vertical direction. A latching recess 16 is formed. The trapezoidal recessed portion 24 includes vertically extending side surfaces 24 a and 24 b and upper inclined side surfaces 24 c and 24 d extending obliquely upward from the upper ends of the side surfaces 24 a and 24 b toward the vertically recessed portion 25. The vertical recess 25 is continuously connected to the upper end of the trapezoidal recess 24 at the lower end. That is, the vertically extending side surfaces 25a and 25b of the vertically recessed portion 25 are continuously connected to the upper end portions of the upper inclined side surfaces 24c and 24d of the trapezoidal recessed portion 24 at the lower end portions. Therefore, the latching recess 16 has a shape that allows the hook 60 to be easily fitted into the recess 16 (particularly, the large trapezoidal recess 24) and to be easily fitted into the vertical recess 25 when it is loosely fitted at one end. However, the latching recess 16 may have any other shape as long as the hook 60 has a shape that can be easily fitted into a recess (in this example, the recess 25) of the movable member 40 described later.

  As can be seen from FIG. 1 to FIG. 3, the hanging portion main body portion 20 of the rear frame 4 has a pair of long portions on both sides in the vicinity of the lower end of the vertical concave portion 25 on the front side of the latching concave portion forming plate-like portion 22. A shaft support structure portion 28 including hole forming portions 26 and 27 is provided. The long hole forming portions 26 and 27 cooperate with the corresponding wall surface portion of the latching concave portion forming plate-like portion 22 to open at the vertical concave portion 25 and to define long holes or grooves 26a and 27a that are long in the vertical direction. 26b, 27b and end wall portions 26c, 27c. The end wall portions 26c and 27c may not be provided.

  As can be seen from FIG. 2, the switch structure 30 is attached to the front side of the wall portion located above the vertical recess 25 in the latching recess forming plate-like portion 22. The switch structure 30 includes a base portion 31 that extends forward from the latching recess forming plate-like portion 22 and a push button 32 that protrudes to the lower surface side of the base portion 31. In the switch structure 30, the push button 32 is movable in the vertical direction B with respect to the base portion 31. When no external force is applied, the push button 32 is elastically biased downward B 1 by a spring (not shown). The latch notification position P1 is taken. When the push button 32 receives the upward force B2, the push button 32 takes the normal latch notification position P2 pushed toward the base portion 31 in the B2 direction. Note that the position P2 need not be limited to the upper end (back end) position, and may be an area realized when the push button 32 is pushed up by a predetermined amount or more in the B2 direction, for example.

  The rear frame 4 is provided with a danger notification light emitting portion 34 via a support portion 33. The light emitting unit 34 serving as a notification unit includes an LED or a lamp. The light emitting portion 34 is loosely fitted in the opening 2a of the machine mounting plate 2 and when the light emitting portion 34 emits light, the light emitting portion 34 of the timepiece 1 is passed through the opening 2a of the mechanical mounting plate 2 and the opening 6a of the dial 6. The emitted light is visible in the direction D from the front. As long as the clock 1 is substantially visible from the front of the wall clock 1 when the wall clock 1 is on the wall K1 of the wall K, the light emitting unit 34 can be any other one such as the front frame 5 of the frame 10 of the wall clock 1. It may be arranged at a position.

  The light emitting unit 34 is in a light emitting state when the push button 32 of the switch structure 30 adopts the abnormal latch notification position P1 biased in the B1 direction, and the normal latch notification position P2 in which the push button 32 is displaced in the B2 direction. When it is taken, it is connected to a power source (not shown) together with the switch structure 30 so as to be in a non-light emitting state.

  In the above, the notifying means includes the switch structure 30 and the light emitting unit 34. The light emitting unit 34 emits light differently when the push button 32 of the switch structure 30 adopts one of the abnormal latch notification position P1 and the normal latch notification position P2 and the other position. Any light emitting means may be used as long as the state is taken. It should be noted that, instead of notifying the state by light, the latching state is notified by another signal such as an acoustic signal or smell, for example, the latching state is notified by both light and sound. It may be.

  As can be seen from FIGS. 2 and 3, the movable member 40 as the latching state sensing means is positioned at the lower end of the movable member main body 41 and the movable member main body 41 in which the most part is loosely fitted in the vertical recess 25. A rotation shaft portion 42 fixed to the main body portion 41 is provided on the front surface side of the base end portion 41a. The rotating shaft portion 42 extends in the horizontal direction, and both end portions 43 and 44 of the shaft portion 42 protrude outwardly E1 and E2 in the width direction E from the base end portion 41a of the main body portion 41, thereby supporting the shaft. The long hole forming portions 26 and 27 of the portion 28 are loosely fitted into the long holes 26a and 27a. Therefore, the rotating shaft portion 42 of the movable member 40 can move in the vertical direction B within the elongated holes 26a and 27a, and rotates or swings in the F1 and F2 directions around the central axis of the shaft portion 42. It is possible to move. As a result, the movable member 40 or its main body 41 can move in the vertical direction B within the vertical recess 25 and can rotate or swing in the F1 and F2 directions around the shaft 42. The main body 41 may be fitted to the rotation shaft 42 so as to be rotatable around the central axis in the directions F1 and F2, instead of being fixed to the rotation shaft 42. .

  More specifically, as can be seen from FIG. 2 and the like, the movable member main body 41 has a rectangular plate-like base portion 45 that is elongated in the vertical direction and an inward direction from the upper end 46 of the base portion 45 to the front of the timepiece 1. A laterally extending portion 47 extending substantially in the A2 direction and a protrusion 48 extending upwardly in the B2 direction in parallel with the base portion 45 from the extending end of the laterally extending portion 47 are provided. The width in the E direction of the base portion 45 and the laterally extending portion 47 of the movable member main body 41 is slightly smaller than the width in the E direction of the vertical concave portion 25 of the latching concave portion forming plate-like portion 22, and the movable member main body The base portion 45 of the portion 41 is loosely fitted in the vertical recess 25 so that it can move in the vertical direction B and can protrude and retract in the directions F1 and F2.

  Accordingly, in the movable member 40, the movable member 40 is rotated in the F2 direction so that the back surface 45a of the base portion 45 of the movable member main body 41 is substantially flush with the back surface 10a (of the plate-like portion 14a) of the timepiece frame 10. The non-protruding position Q1 (see (a) of FIG. 1, FIG. 2, FIG. 3, and FIG. 6 (a)), and the movable member 40 is rotated in the F1 direction, and the back surface 45a (more Specifically, the corner portion 46a of the upper end 46 of the base body 45 and the vicinity thereof protrude from the back surface 10a of the timepiece frame 10 in the A1 direction, and the projecting rotation position Q2 (FIG. 4, FIG. 5 and FIG. 6B). Can be rotated in the direction of F1 and F2.

  The movable member main body 41 and the long holes 26a and 27a are arranged so that the tip end or the upper end 48a of the protrusion 48 is formed when both end portions 43 and 44 of the rotating shaft portion 42 are positioned at the lower ends 26d and 27d of the long holes 26a and 27a. The switch structure 30 is separated from the push button 32 and positioned below the button 32, the movable member 40 is in the non-projecting position Q1, and both end portions 43 and 44 of the rotating shaft 42 are the upper ends 26e of the long holes 26a and 27a. , 27e or the vicinity thereof, the tip 47a of the projection 47 has a length in the vertical direction so that the push button 32 can be pushed up to the normal latch notification position or region P2 in the B2 direction.

  Note that the movable member main body 41 typically has both ends 43 and 44 of the rotating shaft portion 42 positioned at the lower ends 26d and 27d of the long holes 26a and 27a, as can be seen from FIG. 4, for example. Even when the main body 41 is in the projecting rotation position Q2 rotated or swayed in the F1 direction, the protrusion 48 of the movable member main body 41 protrudes outward from the vertical recess 25 in the F1 direction. The upper end wall 25c has a length that can be avoided. In order to avoid protrusion of the protrusion 48 in the F1 direction, the protrusion 48 of the movable member main body 41 has an E direction width larger than the width of the vertical recess 25 in the E direction instead. Also good. The protrusion 48 in the F1 direction may be regulated by any other locking means formed as desired on at least one of the hook main body 20 and the movable member 40. .

  The vertical length of the base portion 45 of the movable member main body 41 is sufficiently shorter than the vertical length of the vertical recess 25, and the protrusions 43 and 44 of the shaft portion 42 of the movable member 40 are elongated holes. When positioned at the lower ends 26d, 27d of 26a, 27a, the lower end 45a of the base portion 45 of the movable member main body 41 is positioned above the lower end portion of the vertical recess 25, and the lower portion of the vertical recess 25 is It remains as a hook receiving groove 25d (see FIG. 4) that allows the hook 60 to be fitted.

  A compression spring 50 as an elastic biasing means is disposed between the substrate portion 23 of the front plate-like portion 12 and the base portion 45 of the movable member main body portion 41. The compression spring 50 pushes the base portion 45 of the movable member main body portion 41 substantially in the A1 direction and tries to rotationally displace the movable member main body portion 41 around the shaft portion 42 in the F1 direction. The extension force of the compression spring 50 is strong enough to cause the movable member main body 41 to protrude in the F1 direction, but is movable when the back surface 10a of the frame 10 of the timepiece 1 is located close to the wall surface K1 of the wall portion K. When the rotation of the member main body 41 in the F1 direction is restricted by the wall surface K1, it is weak to the extent that the movable member main body 41 cannot protrude in the F1 direction due to the restriction.

  Since the movable member 40 needs to be displaced in the B1 and B2 directions with respect to the hanging portion 20, the compression spring 50 applies the rotational force in the F1 direction to the movable member 40 regardless of the position of the movable member 40 in the B direction. Keep it in effect. For this purpose, for example, both end portions of the compression spring 50 are substantially fixed to the spring receiving portion of the substrate portion 23 and the spring receiving portion of the base portion 45 so that the compression spring 50 is slightly curved at the intermediate portion. Even in this case, either one of the end portion of the compression spring 50 that contacts the substrate portion 23 and the end portion that contacts the base portion 45 is fixed to the corresponding portion, and the other end portion is movable. Even if the member 40 slides with respect to the corresponding part according to the displacement in the B direction, both ends of the compression spring 50 slide with respect to the corresponding part (the substrate part 23 and the base part 45), respectively. You may contact | abut possible. When the end portion of the spring 50 is in sliding contact, a guide structure capable of relative sliding in the B direction may be provided between the end portion and the base portion 45 of the movable member 40. In the case of relative sliding, a shaft body may be provided at the center so that the compression spring 50 can maintain its linear shape, and the shaft body is rubber so that the shaft body can be slightly deformed. It may consist of. Further, as the elastic biasing means, instead of the compression spring as illustrated, other torsion springs such as a torsion spring that is loosely fitted to the shaft portion 42 and exerts F1 direction turning force on the movable member main body portion 41 with respect to the hanging portion main body portion 20. It may be a thing.

  As described above, the rotation / translation mechanism 17 includes the elongated holes 26 a and 27 a of the shaft support structure 28 of the hook body 20 and the protrusions 43 and 44 of the shaft 42 of the movable member 40. However, instead, a long hole may be formed in the movable member 40, and a protrusion part loosely fitted in the long hole may be formed in the hanging part main body part 20.

  Next, the operation of the latching structure of the timepiece 1 or the hanging portion 15 when the wall clock 1 constructed as described above is hooked to the hook or the metal fitting 60 along the wall surface K1 of the wall portion K will be described.

  Note that the hooking tool 60 typically includes a shaft portion 61 protruding from the wall portion K, and a locking portion 62 that stands at the tip of the shaft portion 61 and rises above the shaft portion 61 in the upper direction B2. In the illustrated example, the hooking tool 60 includes a set screw screwed into the wall portion K, the shaft portion 61 includes the shaft portion of the set screw, and the locking portion 62 includes the large-diameter head portion of the set screw. As long as 60 is provided with the axial part 61 and the latching | locking part 62, what kind of other thing may be sufficient. As the hook 60, it is preferable to prepare a dedicated metal fitting according to the shape and structure of the latch structure 15 of the wall clock 1, but in practice, a general-purpose set screw or the like may be used. For this reason, it is desired that safe hooking can be performed even on the hook 60 made of a normal set screw.

  Before the wall K is attached to the hook 60, when the wall clock 1 is oriented in the same direction as when it is attached (the direction at 12 o'clock is the upper side), the wall clock 1 takes a state as shown in FIG. That is, the movable member 40 is displaced downward B1 with respect to the rear frame 4 constituting the watch frame body 10, and the shaft portion 42 of the movable member 40 is positioned at the lower end 27d of the elongated hole 27a and the like of the shaft support structure portion 28. The lower end position is taken. Further, the movable member 40 is rotated in the F1 direction by the A1 direction extension force of the compression spring 50, and the corner portion 46a of the end portion 46 protrudes from the back surface of the rear frame 4 in the A1 direction. The tip 48a of the portion 48 is held in a state Q21 in which the tip 48a is in contact with and locked to the upper end wall 25c of the recess 25. This state Q21 is a state (lower protruding rotation position) Q21 in which the shaft portion 42 of the movable member 40 is at the lower end position among the states in which the movable member 40 is in the protruding rotation position Q2. In this state Q21, the upper end 48a of the protrusion 48 of the movable member 40 is separated from the push button 32 of the switch structure 30, the push button 32 takes the abnormal latch notification position P1, and the light emitting unit 34 emits light.

  When the wall clock 1 is hooked on the hook 60 on the wall K, the wall clock 1 is mounted on the wall K from the back side so that the head 62 of the hook 60 is loosely fitted in the trapezoidal recess 24 of the wall clock 1. Is brought close to or in contact with the A1 direction. As a result, the movable member 40 has a corner 46a protruding rearward substantially along the back surface 10a of the wall portion 22 (wall portion 14a), and the back surface 45a of the base portion 45 of the movable member 40 is substantially flush with the surface 10a. Is returned in the F2 direction to the non-projecting position Q1. At this time, the movable member 40 takes substantially the same position or state as shown in FIG. Strictly speaking, this state is the lower non-projecting position Q11 in which the shaft portion 42 is located at the lower ends 26d and 27d of the long holes 26a and 27a in the non-projecting position Q1 of the movable member 40.

  Next, the wall clock 1 is lowered with respect to the wall portion K while the back surface of the wall clock 1 is brought close to the wall surface K1. When the hook 60 is properly fitted in the trapezoidal recess 24 of the wall clock 1, the shaft 61 of the hook 60 is thereby guided by the inclined surface 24 c or 24 d of the trapezoidal recess 24 and the vertical recess 25. Fit into the lower end 25d. When the wall clock 1 is further lowered in the B1 direction, the movable member 40 loosely fitted and engaged in the vertical recess 25 is also lowered in the B1 direction with respect to the wall portion K, and the lower end 45a of the base portion 45 of the movable member main body 41 is moved. It abuts on the shaft portion 61 of the hook 60. Accordingly, as the clock frame 10 of the wall clock 1 further descends in the B1 direction, the movable member 40 is pushed up in the B2 direction relative to the wall portion 22 of the hanging portion main body 20 by the hooking tool 60. In the up-down direction recessed part 25, it moves to B2 direction. With the relative movement of the movable member 40 in the B2 direction, the tip 48a of the projection 48 of the movable member 40 comes into contact with the push button 32 of the switch structure 30 in the state P1, and further, the push button 32 is moved in the B2 direction. Push up. Due to the further relative displacement of the movable member 40 in the B2 direction, the movable member 40 moves in the B2 direction until the upper end portion 46 of the base portion 45 abuts against the upper end wall 25c of the vertical recess 25. When the upper end portion 46 of the base portion 45 of the movable member 40 comes into contact with the upper end wall 25c of the vertical recess 25, the movable member 40 moves in the B2 direction with respect to the hanging portion main body portion 20, in other words, the hook of the timepiece frame body 10. The movement of the clock 1 in the B1 direction is stopped, and the wall clock 1 is hooked at the lower end 45a of the base body 45 of the movable member 40 with respect to the shaft 61 of the hook 60 located in the recess 25, and the wall clock 1 is latched. Is completed. This state Q12 of the movable member 40 is such that the movable member 40 is in the non-projecting position Q1, and the shaft portion 42 of the movable member 40 is located at the upper non-projecting position at or near the upper end positions 26e, 27e of the long holes 26a, 27a. Q12, that is, the normal engagement position Q12. When the upper end portion 46 of the base portion 45 of the movable member 40 moves in the direction B1 in the concave portion 25 until the upper end portion 46 abuts on or near the upper end wall 25c of the concave portion 25, the protruding portion 48 of the movable member 40 becomes the upper end portion. At 48a, the push button 32 of the switch structure 30 is pushed in the B1 direction and positioned at the position P2. As a result, the light emitting unit 34 is extinguished, and it can be visually recognized from the state of the light emitting unit 34 that the predetermined hooking of the wall clock 1 has been completed. Such a predetermined hooking state is as shown in FIG. 1 (a), FIG. 2 and FIG.

  On the other hand, the case where the wall clock 1 is not positioned at a proper position with respect to the wall surface K1 of the wall K and the back surface of the wall clock 1 is separated from the wall surface K1 of the wall K will be described next.

  Before the wall clock 1 is attached, the wall clock 1 takes the state shown in FIG. 4 as described above. Assume that the wall clock 1 in this state is hung on the hook 60 while the back surface 10a of the clock frame 10 of the wall clock 1 is separated from the wall surface K1 of the wall K. In this case, the back of the wall clock 1 is close to the wall surface K1 of the wall K to some extent in the A1 direction, but is not sufficiently close to the wall surface K1, and the head of the hook 60 is placed in the trapezoidal recess 24 of the wall clock 1. The wall clock 1 is positioned with respect to the hook 60 so that the portion 62 is loosely fitted, and the wall clock 1 is further lowered in the B1 direction. When the wall clock 1 is lowered in the B1 direction, the hooking tool 60 comes into contact with the inclined surface 24c or 24d of the trapezoidal recess 24, is guided by the inclined surface 24c or 24d, and is fitted into the vertical recess 25. It hits the lower end 45a of the base portion 45 of the movable member 40 at the protruding rotation position Q21 (FIG. 4). When the wall clock 1 is further lowered, the movable member 40 is moved in the B2 direction relative to the hanging portion main body portion 20 along the vertical concave portion 25 of the wall portion 22 while maintaining the protruding rotation position Q2 by the action of the spring 50. The The movement in the B2 direction stops when the upper side surface 47a of the laterally extending portion 47 of the movable member 40 comes into contact with the upper end portion 25c of the vertical recess 25. As a result, as shown in FIG. 5B, the wall clock 1 has pushed the movable member 40 in the F1-direction swinging position to the upper end position while keeping the projecting rotation position Q2 (upward projecting). It is supported by the hooking tool 60 at the rotation position Q22).

  In this state, since the back surface 10a of the rear frame 4 of the clock frame 10 of the wall clock 1 is considerably separated from the wall surface K1 of the wall K, the support of the wall clock 1 by the hook 60 is unstable, and an earthquake or other external force When the wall clock 1 is hung on the wall clock K or the wall K or the wall K of a room that is susceptible to vibration such as a child room, the wall clock 1 swings with respect to the wall K, etc. There is a risk of falling off 60 and falling.

  However, in this state, as can be seen from FIG. 5B, the protruding portion 48 of the movable member 40 takes a state of rising in the B2 direction along the inner surface of the wall portion 22, and from the inner surface of the wall portion 22. Is further away from the push button 32 located inward (A2 direction) by a distance G in the A direction. As a result, in this case, although the movable member 40 is pushed up in the B2 direction by the hooking tool 60, the push button 32 is not pressed by the protrusion 48 of the movable member 40 and is biased in the B1 direction. The non-normal latch notification position P1 is maintained. Accordingly, in this case, the light emitting unit 34 is kept in a light emitting state, and the light emission of the light emitting unit 34 is visible in the D direction from the front through the openings 6a and 2a. Therefore, even though the wall clock 1 appears to be hanging on the hook 60 at the original position, it is easily recognized by the light from the light emitting unit 34 that the wall clock 1 is not on the normal position. obtain.

  As described above, the movable member 40 takes the position Q22 not only when the back surface 10a of the frame 10 of the wall clock 1 is separated from the wall surface K1 of the wall portion K from the beginning of the wall clock 1, Initially, even if the wall clock 1 is correctly hooked to the hook 60 so that the movable member 40 takes the normal engagement position Q12, the subsequent vibration (the vibration that is easily received such as a child's room or the wall clock itself) The surface of the frame 10 of the wall clock 1 due to an artificial vibration such as contact of a person or an object with respect to the object, vibration or vibration such as an earthquake, or partial removal (loosening) of the hook 60 from the wall K. This may occur when 10a is separated from the wall surface K1.

  In the latter case, the watch frame body 10 is separated from the wall surface K1 of the wall portion K in the A2 direction even when the hanging portion 15 is initially in the state shown in FIG. 2 (the movable member 40 is at the position Q12). The position is shifted. As a result, a considerable gap is formed between the back surface 10a of the timepiece frame 10 and the wall surface K1 of the wall portion K, and the main body portion 41 of the movable member 40 that receives the A1 direction biasing force by the compression spring 50 is It is turned around in the F1 direction. When the distance from the wall surface K <b> 1 of the back surface 10 a of the frame body 10 is increased to some extent, the distal end portion 48 a of the protruding portion 48 of the movable member main body portion 41 is rotated by the F1 direction rotation of the movable member main body portion 41. It deviates from the push button 32 in the A1 direction, and takes a position as shown in FIG.

  In the above description, when the push button 32 of the switch structure 30 and the protrusion 48 of the movable member 40 are engaged, the spring force of the spring 50 is applied to the wall portion K by the spring force itself. It is set weak to such an extent that a situation such as separation from the wall surface K1 does not occur.

  In any case, in this case, for example, the frame of the wall clock 1 is pressed against the wall surface K1 in the A1 direction so that the rear surface of the frame 4 is substantially in contact with the wall surface K1 of the wall K. Accordingly, the pressing member 40 may be swung in the F2 direction against the spring force of the spring 50, and the movable member 40 may be set at the position shown in FIGS. 1 to 3 (the hook 60 is loosened). In this case, tighten the hook 60). It should be noted that the push button 32 is moved in the H direction (FIG. 5B) so that the tip 48a of the protrusion 48 can be properly engaged with the push button 32 as the movable member 40 swings in the F1 direction. It may be possible to swing, or the corresponding edge of the projection 48 of the push button 32 or the movable member 40 may be rounded or tapered.

  However, since it is usually difficult to know until the movable member 40 is at the position Q22, when the light emitting unit 34 notifies that the movable member 40 is not in the normal position, preferably the wall clock is used. It is preferable to lift 1 in the B2 direction to once release the latch by the hook 60 and then reposition the wall K of the wall clock 1 with respect to the wall surface K1. Therefore, it is possible not to dare to swing the push button 32 or change the shape of the related portion so that it is difficult to be hooked at the normal position.

  The hooking failure of the wall clock 1 is not limited to the example shown in FIG. 5, and the hooking tool 60 is not originally fitted in the original recess 25, and the hooking tool 60 is not the lower end 45 a of the base portion 45 of the movable member 40. There may be cases where it is not hit. In such a case, when the back surface 10a of the frame 10 of the wall clock 1 is actually in contact with the wall surface K1 of the wall K (FIG. 6 (a)), the back surface 10a of the frame 10 of the wall clock 1 is the wall. There is a time when it is away from the wall surface K1 of K ((b) of FIG. 6).

  In the former case, the movable member 40 is not pushed up in the B2 direction by the hooking tool 60 as shown in FIG. The movable member 40 remains in a state where the shaft portion 42 of the movable member 40 hits the lower end portion 27d of the elongated hole 27a and the like, and the movable member 40 takes the lower non-projecting position Q11. Therefore, as can be seen from FIG. 6A, the upper end 48 a of the protrusion 48 of the movable member 40 remains separated from the push button 32 of the switch structure 30. As a result, the push button 32 stays at the position P1, the light emitting unit 34 remains in the light emitting state, and the light from the light emitting unit 34 notifies that the wall clock 1 is not locked at the normal position.

  In the latter case, as shown in FIG. 6 (b), the movable member 40 is lowered in the B1 direction with respect to the latching main body portion 20 of the frame 10, and the shaft portion 42 of the movable member 40 has a long hole 27a or the like. Since the rear surface 10a of the frame body 10 is separated from the wall surface K1 of the wall K, the movable member 40 is swung in the F1 direction by the spring 50, that is, The lower protruding rotation position Q21 is taken. In FIG. 6B, the corner portion 46a of the movable member 40 is in contact with the wall surface K1 of the wall portion K, but the back surface 10a of the frame body 10 is greatly separated from the wall surface K1 of the wall portion K. It is also possible to be away from the wall surface K1. In any case, since the tip 48a of the protrusion 48 of the movable member 40 is separated from the push button 32 of the switch structure 30 even in this state, the push button 32 takes the position P1, and the light emitting unit 34 emits light. , It is notified that the wall clock 1 is not latched at the proper position.

  In the above, the non-projecting position Q1 of the movable member 40 corresponds to the reference proximity position, and the projecting rotation position Q2 corresponds to the separation warning position. Further, as described above, the normal engagement position corresponds to the upper non-projection position Q12 in the non-projection position Q1 that is the reference proximity position.

  In the above, the movable member 40 as the latching state detecting means can rotate in the F direction with respect to the hanging portion main body 20 and can rotate and translate in the B direction with respect to the hanging portion main body 20. Although the example of the member has been described, the sensing means may be, for example, a movable member that is translatable in the front-rear direction and is movable in the up-down direction and is engaged with the hanging portion main body, in the front-rear direction and the up-down direction. Even if it is a movable mechanism which can rotate, the movable mechanism which can translate in the front-back direction and an up-down direction may be sufficient. The movable mechanism may be composed of a plurality of independently displaceable movable members.
