Description

  The present invention relates to a shoji device that can easily replace a sheet-like body stretched along a lattice body inside a rectangular shoji frame body according to the situation.

  Shoji is traditionally used as a fitting with many excellent properties, such as being able to feel outside while maintaining privacy while maintaining a certain level of heat insulation. Yes. In recent years, in the industrialization and westernization of architecture, woody materials or Japanese paper materials are preferred, and in addition to partitioning fixture applications, they are also frequently used as inner sashes for aluminum sashes.

  In addition to these basic functions, various techniques have been added in order to increase added value, and ingenuity has been proposed to improve product value and usability. For example, a vertically long storage portion is formed inside a vertical fence facing parallel to the left and right, and vertical support shafts are attached to the left and right storage portions, respectively, so that the left and right sides of the shoji paper that are long and continuous are attached to the left and right sides. A shoji paper wound around the support shaft has been proposed. In this shoji, when the shoji paper is wound in one downpile, the new shoji paper for that length is drawn out and replaced by the other downpipe, so that there is an effect that it is possible to save the trouble of re-upholstery. (For example, refer to Patent Document 1).

  However, the size of the storage unit is limited because the thickness of the frame of the shoji is limited for the convenience of storage. Therefore, when the shoji paper is wound around the support shaft in such a narrow storage section, the outer diameter of the paper expands, and the winding operation becomes difficult. As described above, since the winding operation or the pulling out operation from the other storage portion is not smooth, the operability is poor and the shoji paper may be excessively pulled and torn, and conversely, the movement on the winding side is hindered. If there is, there is a problem that the shoji paper becomes slack and looks bad.

  In the present embodiment, as shown in FIG. 2, the grid body 7 includes a grid unit 37 in which a vertical grid 7B and a horizontal grid 7D are integrally bridged inside an outer peripheral frame 7A having substantially the same size as the rectangular opening 5. Constructed using. Further, the lattice unit 37 is divided into substantially the same thickness in the thickness direction, and is divided into a fixed lattice unit 37F and a movable lattice unit 37M.

  The fixed grid unit 37F is fixed to the rectangular opening 5 of the shoji frame 6 by actual rowing or adhesion. As shown in FIG. 5, the movable lattice unit 37 </ b> M has convex portions 38 that are vertically continuous on both sides of the outer peripheral frame 7 </ b> A. On the inner surface facing the rectangular opening 5, a support groove 39 continuous in the vertical direction is formed. The movable grid unit 37M is detachably attached to the shoji frame 6 by inserting the left and right convex portions 38, 38 into the support grooves 39, 39 and sliding from above. At this time, a split groove 15 of, for example, about 1 to 5 mm is formed between the fixed grid unit 37F and the movable grid unit 37M attached between the support grooves 39 and 39. Moreover, the split groove 15 is formed to communicate with the slits 14 formed in the upper rail 3 and the lower rail 4 in the vertical direction. In the present specification, the dividing groove 15 refers to a gap formed at the center of the lattice body 7.

  The sheet displacing means 9 includes a winding shaft group 12G attached to the space 10 and a driving means 13. As shown in FIGS. 3 and 6, the winding shaft group 12G has an inner winding shaft 12U arranged on the inner side near the rectangular opening 5, and an outer side arranged parallel to the opposite side with a space therebetween. It consists of a winding shaft 12S.

  As shown in FIG. 3, a horizontal round hole 49 is formed at a position facing the void 10 of the downboard 2 with a vertical gap, and a tubular bush is fitted into the round hole. Shaft support portions 11 are formed. By inserting both end portions of the inner and outer winding shafts 12U and 12S into the upper and lower shaft support portions 11 and 11 of the left and right vertical rods 2, the inner and outer winding shafts 12U and 12S can be rotated. Supported. In this embodiment, as shown in FIG. 4, one end portion of the inner winding shaft 12 forms a rotating body 17 disposed across the vertical groove 40 of the vertical rod 2.

  As shown in FIG. 7, the winding shaft 12 of this embodiment is divided into two parts and integrated by a detachable joining means 42. The joining means 42 includes a screw hole 42A provided on one split shaft in the axial direction, a screw rod 42B projecting in the axial direction on the other split shaft and screwable into the screw hole 42A, and the screw rod. It consists of a nut 42D screwed on 42B. Accordingly, after the winding shaft 12 whose length has been shortened by deeply screwing the screw rod 42B into the screw hole 42A is inserted into one of the shaft support portions 11, the winding shaft 12 is extended by rotating the screw rod 42B. The other end is inserted into the opposite shaft support 11 to support both ends. Next, when the nut 42D is tightened toward the screw hole 42A and is loosened by a so-called double nut mechanism, the two-part winding shaft 12 can be rigidly integrated and can be bridged between the shaft support portions 11 and 11. The use of the two-divided type receiving shaft 12 provided with the joining means 42 in this way is preferable in that the initial assembly work can be easily performed, and maintenance such as replacement of the sheet-like body 8 can be improved.

  In this embodiment, as shown in FIGS. 3 and 6, an endless belt belt 43 is belted between the inner and outer winding shafts 12U and 12S. As shown in FIG. 2, the belt belt 43 has three wide belts in the center and one narrow belt on each side, and a total of five are spaced apart at equal intervals. A cooperation means 22 for synchronizing the rotation of the winding shafts 12U and 12S is formed. By providing such cooperation means 22, both shaft rotations can be accurately linked.

  As shown in FIG. 6, a horizontal bar 44 having a vertically-long rectangular cross section supported at both ends by the vertical rod 2 is provided at the center of the space 10, and a pair of rotatable bars on the upper and lower surfaces of the horizontal bar 44. When the bearing member 46 having the mini rolls 45 and 45 is provided, a bending force acting on the winding shaft 12 when the sheet-like body 8 is wound is supported, which is preferable in that a smooth winding operation can be performed. .

  The diameter of the winding shaft 12 is, for example, about 5 to 20 mm, preferably 8 to 15 mm, and in this embodiment, 12 mm. If it is less than 5 mm, the winding diameter of the sheet-like body 8 becomes excessively small, and it becomes easy to get a curl and the shaft strength is insufficient. Conversely, if it exceeds 20 mm, the space 10 becomes narrow, and the sheet-like body 8 Lack of storage space.

  In this embodiment, as shown in FIGS. 2 and 8, the winding shaft group 12 </ b> G is also provided in the space 10 of the lower beam 4 in the same manner as the upper beam 3.

  The driving means 13 can rotationally drive one winding shaft 12 of the winding shaft group 12G. In the present embodiment, the winding shaft group 12G provided on the upper rail 3 is provided with a driving means 13 for rotating the inner winding shaft 12U disposed below and the winding shaft group 12G provided on the lower rail 4. Then, driving means 13 for rotating the inner winding shaft 12U disposed above is provided. Thus, the sheet displacing means 9 of the present embodiment is formed by the upper sheet displacing means 9U provided on the upper rail 3 and the lower sheet displacing means 9S provided on the lower rail 4.

  Further, the driving means 13 of the present embodiment includes a rotating body 17 composed of a region traversing the inside of the longitudinal groove 40 of the longitudinal shaft 2 of the inner winding shaft 12 and a pair of rotating bodies arranged above and below in the longitudinal groove 40. 17 and an endless string 18 spanned between 17 and 17. In the present embodiment, the belt 18B is used as the endless continuous string 18, but other ropes, chains, and the like can also be employed.

  As shown in FIG. 3, a knob 20 is attached to the belt 18B. The knob portion 20 is provided so as to protrude outward from the vertical rod 2 through the narrow window 50 of the lid plate 47. Therefore, by moving this knob 20 up and down manually, the belt 18B is moved up and down, and the rotating body 17 can be reliably rotated. Therefore, using such a simple mechanism, it is preferable in that the winding shaft 12 can be reliably rotated and the sheet-like body 8 can be smoothly wound and unwound thereon. In this embodiment, the operating means 21 for driving the rotating body 17 by the knob 20 is formed.

  The sheet-like body 8 covers the rectangular opening 5 of the shoji frame 6, and is formed by continuously forming two or more types of sheet portions 8B having different designs. Here, the different design includes not only those having different appearance designs, but also a continuous sheet portion 8B made of different materials is effective. For example, when the paper sheet material 8K and the cloth sheet material 8N are made continuous, if the paper sheet material 8K is drawn out into the rectangular opening 5 and used, the ventilation can be blocked and peeping from the outside can be prevented. On the other hand, when the fabric sheet material 8N is pulled out and used, it is very effective when air permeability and a certain degree of see-through are required. In this way, by utilizing the characteristics of the material, it can be used in a multi-functional and convenient manner according to various conditions such as time zone and usage conditions.

  In addition, each sheet portion 8B is vertically aligned with the height of the rectangular opening 5 or a little longer than the height of the rectangular opening 5 so as to be substantially the same length. The sheet portion 8B located in the rectangular opening 5 can be exchanged by performing the winding operation of approximately the same length.

  And, as shown in FIG. 8, the sheet portion 8B using, for example, the cloth sheet material 8N positioned above bridges the inner and outer winding shafts 12U and 12S of the upper rail 3, It is rolled up in an oval cross section. At this time, the leading edge of the cloth sheet material 8N is fixed to the belt belt 43 with an adhesive or the like. Accordingly, since the belt belt 43 that rotates together with the winding shaft 12 rotates at the same speed while pulling the leading edge of the cloth sheet material 8N on the average, the cloth sheet material 8N is wrinkled or loosened. Instead, the belt belt 43 is overlaid between the belt belt 43 and the inner and outer winding shafts 12U and 12S.

  Then, the paper sheet material 8K continuous to the cloth material sheet material 8N wound up on the winding shaft group 12G of the upper rail 3 passes through the slits 14 of the upper rail 3 and further includes the dividing grooves 15 of the lattice body 7. Pass through and go down. Then, it passes through the slit 14 of the lower rail 4 and reaches the space 10 of the lower rail 4, and the lower portion is wound around the winding shaft group 12 </ b> G of the lower rail 4, and its leading edge is attached to the belt belt 43 as described above. It is fixed. When the knob 20 of the drive means 13 is pulled downward from this state, the belt 18B rotates and the upper and lower seat displacement means 9U and the inner receiving shaft 12U of the lower sheet displacement means 9U are rotated via the rotating body 17. Rotate simultaneously. As a result, as shown in FIG. 9, the paper-like sheet material 8K passes through the slit 14 of the lower rail 4 and is wound between the inner and outer winding shafts 12U and 12S of the lower sheet displacement means 9S, and the upper The cloth sheet material 8N wound around the winding shaft group 12G of the sheet displacement means 9U passes through the slit 14 from the upper rail 3 and is drawn out to the split groove 15 of the lattice body 7, so that the entire rectangular opening 5 is covered. cover.

  In this way, when the sheet-like body 8 in which the cloth sheet material 8N and the paper sheet material 8K are continuous is wound on one of the upper and lower sheet displacement means 9S by the driving means 13, the type differs from the other. The sheet portion 8B is pulled out at the same speed. In addition, in this embodiment, the cooperation means 22 that links the inner and outer winding shafts 12U and 12S is provided. Therefore, since the sheet-like body 8 can be smoothly wound and unwound, the operability is excellent, and the sheet-like body 8 drawn out to the rectangular opening 5 is supported without loosening, so that the appearance is good. Furthermore, in this embodiment, since the leading edge of the sheet-like body 8 is fixed to the belt belt 43 constituting the cooperation means 22, the leading end of the sheet-like body 8 is pulled on average during winding. Therefore, it is possible to wind up orderly without causing winding unevenness.

  The shoji device 1 configured in this manner winds the sheet-like body 8 between the inner and outer receiving shafts 12U and 12S and winds the sheet-like body 8 in an oval cross section. Therefore, even if the entire sheet-like body 8 is wound around the space 10 of the upper rail 3 and the lower rail 4, the number of times of winding can be reduced. Therefore, the thickness at the time of winding can be reduced, and the sheet-like body 8 can be accommodated in the space 10 having a limited thickness in a compact manner without any trouble. As a result, the sheet-like body 8 can be smoothly wound up and down.

  Therefore, it is not necessary to increase the thickness of the shoji frame 6 including the upper cross 3 and the lower cross 4, and the appearance can be the same as that of the conventional shoji, so that the appearance is excellent. At the same time, it can be installed in a movable manner between the sill and the duck, so that it can be made exactly the same as a general shoji, so it can be easily renovated only by replacing the shoji as well as at the time of new construction. Further, it can be used in combination with a normal shoji as appropriate, and a necessary number can be arranged at a necessary position.

  Further, since the sheet-like body 8 in the rectangular opening 5 is supported by passing through the inner side of the split groove 15 provided in the lattice body 7, the swing and vibration are suppressed even when receiving wind. Therefore, it is possible to maintain quietness without flapping noise, to prevent the sheet-like body 8 from being damaged, and to improve durability.

  In this embodiment, as shown in FIG. 7, a clutch means 19 that freely allows rotation in the unwinding direction is provided on the inner winding shaft 12U. The clutch means 19 is provided with a saw blade-like engagement portion 19A provided on the separation surface, which is separated from the shaft body, and a push spring 19B is interposed at the end of the inner winding shaft 12U. The engaging portion 19A is configured by applying a certain spring force. This clutch means 19 engages against the spring force when there is a difference in the length of winding in one rotation due to the difference in the number of windings between the upper and lower sheet displacement means 9U, 9S. Since the deviation occurs in the portion 19A, the difference can be absorbed and adjusted. Therefore, the sheet can be rolled up and down more smoothly, and an excessive pulling force or slack is not generated in the sheet-like body 8.

  FIG. 10 illustrates another embodiment. Hereinafter, different contents will be described, and other than that, only the same reference numerals are given to the main components shown in the figure. In the shoji device 1 of this embodiment, the driving means 13 is formed by a dial 48 that is integrally provided at the end of the outer winding shaft 12S and can directly rotate the outer winding shaft 12S in the winding direction. Therefore, the force for operating the dial 48 can directly move the sheet-like body 8 up and down without causing loss or slippage. When the dial 48 is provided on the sliding shoji, the projecting dimension from the surface of the vertical fence 2 is made small in order to prevent interference with the other shoji frame 6.

  FIG. 11 illustrates yet another embodiment. In the shoji device 1 of this embodiment, the sheet displacement means 9 is formed only on the upper rail 3. Then, the sheet-like body 8 wound in an oval cross section between the inner and outer winding shafts 12U and 12S of the upper rail 3 passes through the slits 14 to the split grooves 15 of the lattice body 7. It is extended. A weight 16 extending in the width direction is attached to the lower edge of the sheet-like body 8. Accordingly, when the sheet-like body 8 is pulled out to the rectangular opening 5, the sheet-like body 8 is pulled by the weight of the weight 16 and can pass through the split groove 15. There is no.
