BUILT-IN FRAMEWORK HAVING PAPER SHEET HOLDING FUNCTION

Abstract: This invention relates to a built-in framework having a paper sheet holding function, the framework being of a furniture fitting such as the movable indoor partition material, produced by a pair of framepieces (1, 2), holding a paper sheet (3) tightly between them, with one framepiece, in the form of a male framepiece (2), having a protruding part (21) and having a paper sheet holder (21) which combines correctly with the other framepiece, in the form of a female framepiece (1), to hold a paper sheet (3) between the framepieces.

Description: This invention relates to the improvement of practical techniques used with the framework of furniture fittings such as the indoor movable partition material like Shohji Door (Japanese paper sliding door), Fusuma Door (Japanese Craftpaper sliding door) and so on, and it relates particularly to a built-in framework having the paper sheet holding function, which makes it possible to adhere the relative paper of those materials tightly, correctly, simply and rapidly without any professional techniques. As is well known in the prior art, furniture fittings such as Shohji Door or Fusuma Door consist of an oblong frame and a relative paper sheet separately, and in order to hang the paper on the frame neatly, a long term of apprenticeship, like a professional hanger, is required. For a young married lady, who has been living generally under a dual income family and is called as "A New Family Generation", it is absolutely impossible to during her daily life hang the paper on the frame correctly, and therefore, such a job has had to be entrusted to a specialist, so-called "The professional joiner or hanger" accordingly. However, today there are only a few such professional and skillful people, and thus, their working costs are so high that they would seriously affect the expenditure of general family life at present. For example, a two-storied house with 132 square metres would normally have 30 pieces of Shohji or Fusuma Doors, and with the working cost today at approximately ¥5,000. per piece, the total cost would accordingly come to ¥150,000. This invention has been developed in view of the tendency for daily increasing costs, and it is the main intention of the invention to supply in a simple and easy manner the framework for hanging the paper sheet on the frame, Shohji or Fusuma Door, without any special and professional techniques. This shall be also available for other indoor decorative materials such as Tsuitate (Japanese Paper Screen) or framed tapestry, used as furniture fittings. Prior art specification EP-A-0023807 discloses a panel assembly for securing a solid in-fill panel between a pair of male and female framepieces each pre-arranged to be assembled together, the female framepiece having a hollowed part and the male framepiece having a protruding part, wherein the framepieces can be assembled together. Dowel pegs are used to hold the framepieces together and the in-fill panel is solely held between the framepieces with its outer edges within the hollowed part of the female framepiece and thus clear of the dowel pegs. This panel assembly is unsuitable for use with a paper sheet instead of a solid in-fill panel. At this present stage, an object of this invention is to supply a built-in framework, by which the paper sheet shall be held tightly in tension on the paper sheet holder prepared at a male framepiece, and then it shall be combined with the other, female, framepiece as it is. The job would be accomplished quite simply and instantly. Through the correct and simple procedure, the finish of the Shohji or Fusuma Door would appear exactly the same as the professional jobber's work, and even in case of other interior decorative materials, the finish would be also treated correctly as the first class workmanship as if it was under the skillful hands of a first grade craftsman. Another object of this invention is to supply a built-in framework, with which even an amateur or general person would be able to effect the paper sheet hanging or changing easily and rapidly for a Shohji Door, a Fusuma Door, a Tsuitate Screen or for another framed tapestry with personal intention, while this kind of job should have been entrusted forcibly to the specialist like the professional and skillful jobber. According to the present invention there is provided a built-in framework having a paper sheet holding function comprising, respective male and female framepieces, each pre-arranged to be assembled together, the female framepiece having a hollowed part in its surface, the male framepiece having a protruding part whereon the male and female framepieces can be assembled together, characterised by a paper sheet holder in the form of a pin provided at the protruding part, a paper sheet of a slightly larger size than the protruding part of the male framepiece, and by the male framepiece holding the paper sheet which is penetrated by the paper sheet holder, said framepieces being assembled together to form the assembled framework section. The invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 shows an exploded view of a first embodiment of the invention indicating how each framepiece is constructed; Figure 2 shows an exploded side view of a second embodiment; Figure 3 shows a side view of a Shohji Door completed through the procedure of the second embodiment; Figure 4 shows an exploded side view of a third embodiment, and Figure 5 shows an exploded side view of a fourth embodiment. The drawings show a female framepiece 1, with oblong shape, having a hollowed part 11 in its surface as the built-in section. This hollowed part 11 can be seen as forming a step in the drawings of Figure 1 to Figure 3, but, as shown in Figure 5, this part can also be formed as individual sockets. Thus, this part shall be available in the various styles, to be matched exactly with a protruding part 21 of a male framepiece 2. In Figure 1 to Figure 4, the protruding part 21 is in the style of the frame and is intended to be built-in tightly into the above mentioned hollowed part 11 accordingly. In Figure 5, the protruding part 21 can be seen in the different style of individual plug shapes matching with the sockets 11 in the framepiece 1. In the third embodiment, shown in Figure 4, the male framepiece 2 itself is received into the female framepiece 1, and on the circumference of male framepiece 2, a flange 23 is provided. Reference numeral 22 identifies the paper sheet holder, and as seen in the drawings, it is the needle pin style to be set in the protruding part 21 of the male framepiece or else to be set in the male framepiece directly. This needle pin 22 is received correctly into an associated needle pin hole 12, when the framepieces are received together as indicated in the Figure 1 embodiment example, and in the case of Figure 2 to Figure 5, a hollowed part shall be pre-drilled deeper so that the needle pin point may not reach to the surface of a hollowed part 11. In a case where the female framepiece is made of wood, it is unnessary to prepare a needle pin hole or the like, since the pin itself will penetrate into the wood framepiece directly and smoothly. Reference numeral 3 identifies the paper sheet, consisting of, for example, sliding door craftpaper, or decorative well cloth sheet, and held, in use, under tension. The term 'paper sheet' is intended to be interpreted as including craftpaper and cloth sheet, never as only paper. From the figures it can be seen clearly that the paper sheet 3 is of a slightly larger size than the boundary defined by the protruding part 21. The preferred embodiments of this invention have been mainly explained as above. This invention, however, is not only limited to the above embodiments, but also it is available for such arrangements as defined in the appended claims. The general change of the style, for example, against male/female framepiece, shall be made in accordance with design requests or with other requirements.

Claims: 1. A built-in framework having a paper sheet holding function comprising, respective male and female framepieces (2, 1), each pre-arranged to be assembled together, the female framepiece (1) having a hollowed part (11) in its surface, the male framepiece (2) having a protruding part (21) whereon the male and female framepieces can be assembled together, characterised by a paper sheet holder (22) in the form of a pin provided at the protruding part (21), a paper sheet (3) of a slightly larger size than the protruding part (21) of the male framepiece (2), and by the male framepiece (2) holding the paper sheet (3) which is penetrated by the paper sheet holder (22), said framepieces being assembled together to form the assembled framework section. 2. A framework as claimed in claim 1, wherein the protruding part (21) is formed in the style of the frame. 3. A framework as claimed in claim 1, wherein the protruding part (21) is formed in the style of a plug to be fitted in an associated socket.
