[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a timepiece in which a plate member is fixed to a frame by using a screw, and more particularly, to preventing the spread of shavings generated from the frame by screwing the screw.
[0002]
[Prior art]
2. Description of the Related Art In general, there is known a wooden frame timepiece configured by fixing a plate member supporting a movement to a wooden frame. The plate member is fixed to the frame using screws.
[0003]
[Problems to be solved by the invention]
When the screw is screwed into the frame as described above, shavings are generated from the frame.
[0004]
As a countermeasure against such shavings, there has been proposed a type in which shavings are captured by an adhesive member provided at a predetermined position, such as a wooden frame clock described in Japanese Utility Model Publication No. 7-33192. ing.
[0005]
However, when the shavings are captured by the adhesive member, the viscosity of the adhesive member gradually deteriorates due to drying or the like, and the possibility that the captured shavings are suddenly diffused is remarkable.
[0006]
The wooden frame mounting structure described in Japanese Utility Model Registration Publication No. 2502669 has been proposed by the applicant of the present application, and has a required portion provided with an elastic holding material.
[0007]
With this mounting structure of the wooden frame, the fear that the viscosity is deteriorated is eliminated. However, the ability to capture shavings is rather weak, and further improvements are required.
[0008]
In view of such circumstances, an object of the present invention is to provide a timepiece that can more efficiently prevent the diffusion of shavings generated from a frame by screwing a screw.
[0009]
[Means for Solving the Problems]
The invention described in the first claim of the present application is a timepiece in which a plate member is fixed to a frame using screws, a sponge is attached between the frame and the plate member, and the sponge is formed of the screw. A timepiece that covers the screw-in portion, has a thickness after mounting smaller than the thickness before mounting, and is in a compressed state. According to such a configuration, the timepiece is generated from the frame by screwing in the screw. Diffusion of shavings is efficiently prevented.
[0010]
That is, the present invention suppresses shavings between the frame and the sponge and between the screw and the sponge, and according to the compression of the sponge, the contact pressure of the sponge with the frame and the screw is sufficiently ensured. You. Therefore, shavings are more reliably captured.
[0011]
In particular, when the shavings are captured by the adhesive member, the viscosity of the adhesive member gradually deteriorates due to drying or the like, and the possibility that the captured shavings are unexpectedly diffused is remarkable. , Such disadvantages are satisfactorily avoided.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, specific examples of the present invention will be described in detail with reference to the drawings.
[0013]
As shown in FIGS. 1 to 6, the timepiece 1 according to the present embodiment has a plate member 300 (a book) in which a dial 310, hands 320, and a movement 330 are arranged on a wooden or synthetic resin frame 200 surrounding the periphery thereof. In the example, an MDF board is fixed.
[0014]
Further, a transparent plate 400 made of glass or acrylic is fitted in the frame 200, and an annular spacer 500 is arranged between the plate member 300 and the transparent plate 400.
[0015]
The frame 200 of the present example includes a seating surface 210 of the plate member 300 and a seating surface 220 of the transparent plate 400, and the plate member 300 covers the transparent plate 400 and the spacer 500 from the rear side of the frame 200. It is fixed using screws 600.
[0016]
The seating surface 210 of the plate member 300 is provided with a concave portion 211 into which the screw 600 is screwed, and a key portion of the plate member 300 is provided with an insertion portion 301 through which the screw 600 is inserted. The recess 211 is a screwed portion of the screw 600. Although the insertion portion 301 is illustrated as a cutout formed at the edge of the plate member 300, the insertion portion 301 may be a hole.
[0017]
Further, a plurality of such recesses 211 and insertion portions 301 are provided at appropriate intervals around the timepiece 1, and the frame 200 and the plate member 300 are firmly fixed by a plurality of screws 600.
[0018]
Further, the plate member 300 of the present example has a dial 310 and hands 320 provided on the front, and a movement for driving the hands 320 provided on the back. The dial 310 and the hands 320 fix the frame 200 and the plate member 300 and are arranged inside the transparent plate 400.
[0019]
In such a configuration, when the screw 600 is screwed into the concave portion 211, some shavings are generated from the frame 200. Therefore, in this example, a sponge 700 that covers the concave portion 211 is mounted between the frame 200 and the plate member 300, and shavings are pressed between the frame 200 and the sponge 700 and between the screw 600 and the sponge 700. Thus, the diffusion of shavings is prevented.
[0020]
The sponge 700 is a spongy rubber or synthetic resin member, and is interposed between the plate member 300 and its seating surface 210 in a compressed state.
[0021]
That is, for sponges 700, than before mounting the thickness t _{1 (see} FIG. 5), the thickness t ₂ after mounting _(see Fig. 6) is set smaller. The thickness of the sponge 700 is a dimension of the sponge 700 in the screwing direction of the screw 600.
[0022]
The sponge 700 is pierced by a screw 600 to fix the frame 200 and the plate member 300 and to be compressed.
[0023]
The contact pressure of the sponge 700 against the frame 200 and the screw 600 is sufficiently ensured by the compression of the sponge 700, so that shavings are reliably formed between the frame 200 and the sponge 700 and between the screw 600 and the sponge 700. Is captured by
[0024]
As described above, the timepiece 1 according to the present embodiment captures shavings generated from the frame 200 by the compressed sponge 700, and can efficiently prevent the shavings from spreading.
[0025]
Note that the sponge 700 may be configured to be attached to the insertion portion 301 or the concave portion 211 with an adhesive in advance, as shown in FIG. 7, for example. According to such a configuration, the operation of screwing the screw 600 can be easily performed. Here, the screw 600 is screwed in after the adhesive is sufficiently dried in order to prevent the sponge 700 from being displaced.
[0026]
Further, in this example, by providing the concave portion 211 in the frame 200, the damage of the frame 200 due to the screwing of the screw 600 is prevented, and the amount of shavings is reduced. However, if there is a concern about such breakage or relatively little shavings, the screw 600 may be directly screwed into the plane of the frame 200 without providing the recess 211. In other words, the screwed portion of the screw 600 is a key point on the plane of the frame 200, and in this case, the processing of the recess 211 can be omitted. ,
As described above, according to the timepiece of this example, a sponge is mounted between the frame and the plate member, and the sponge covers the screwed portion of the screw, and the thickness after mounting is larger than the thickness before mounting. Also, since it is small and in a compressed state, it is possible to efficiently prevent the shavings generated from the frame by screwing the screws in from spreading.
[0027]
That is, in this example, shavings are suppressed between the frame and the sponge, and between the screw and the sponge. According to the compression of the sponge, a sufficient contact pressure of the sponge with the frame and the screw is secured. be able to. Therefore, shavings can be more reliably captured.
[0028]
