Description

  The present invention relates to a thin laying tatami frame member that can be easily assembled and disassembled.

  In order to meet the desire to seek the same comfort as a Japanese-style room in a Western-style room, a space like a Japanese-style room is laid out on the flooring with multiple tatami mats that are about the size of a half tatami mat called a “laying tatami mat”. Is widely done.

  The laying tatami mat has a slipper on the bottom, but it is only laid on the flooring. An impact may cause a misalignment between the laying tatami mats.

  Therefore, in order to prevent such positional displacement between the laying tatami mats, it is generally performed to surround the laying tatami mats using a frame member called a “laying tatami frame member”.

  Here, the structure of the frame member for laying tatami mats will be briefly described. The frame member for laying tatami mats is prepared with a plurality of long and rod-shaped frame constituent members made of wood, synthetic resin, etc. The side surfaces of the constituent materials are connected to each other and assembled into a frame shape.

  The present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing a frame member 10 for laying tatami according to the first embodiment of the present invention.

  As shown in this figure, the frame member 10 for laying tatami mats is positioned between the laying tatami mats A by surrounding a plurality of (4 in this embodiment) laying tatami mats A on the floor surface. In order to prevent this, the four frame members 12 (12a, 12b, 12c, 12d) are connected to each other to form a rectangular frame shape.

  Each frame constituent member 12 (12a, 12b, 12c, 12d) is roughly constituted by a frame constituent member main body 14, a male side connecting member 16, and a female side connecting member 18.

  The frame component main body 14 is a long rod-shaped member formed of medium density fiberboard (MDF), and its upper surface 14a is opposed to the inner periphery 14b side which is the long side on the side adjacent to the laying mat A. It is formed in a taper shape that inclines downward toward the outer periphery 14c (see FIG. 2).

  In addition to the MDF described above, a solid material, a laminated material, a resin material, or the like can be used as the material of the frame constituent material body 14. In addition, in this embodiment, the length of each frame component main body 14 was laid in a square shape by two vertically and horizontally when they were connected to constitute a frame member 10 for placing a rectangular frame. It is set to a length that can surround the four tatami mats A, but is not limited to this. For example, six tatami mats A that are laid in a square shape three by three in the vertical and horizontal directions. What is necessary is just to set suitably according to the number of the installation mat | matte A to lay, such as setting to the length which can surround the circumference | surroundings.

  On the bottom surface of the frame component main body 14, a male-side connecting member mounting recess 20 is formed at one end portion in the longitudinal direction (corner side end portion) that opens toward the inner periphery 14b, and the other end portion in the longitudinal direction. A female-side connecting member mounting recess 22 is formed at the (connecting-side end) that opens to the connecting-side short side 14d orthogonal to the inner periphery 14b (see FIG. 3).

  A male side connecting member 16 to be described later is attached to the male side connecting member mounting recess 20, and a female side connecting member 18 to be described later is attached to the female side connecting member mounting recess 22. ing.

  The male side connecting member 16 has an attachment portion 16a and a locking piece 16b.

  The attachment portion 16a is a thin plate-like portion made of a rigid material such as metal, and the thickness x is set to be the same as or slightly larger than the thickness a on the outer periphery 14c side of the frame component 14 (therefore, the attachment portion). The depth of the male connecting member mounting recess 20 to which 16a is mounted is approximately equal to the thickness x of the mounting portion 16a or slightly deeper than this.

  Two long holes 24 for fixing screws are formed in the mounting portion 16a at a predetermined interval. By screwing the two screws N into the long holes 24, the male side connecting member 16 has a frame configuration. A screw is fixed to the material main body 14. And the locking piece 16b is extended from the attaching part 16a.

  The locking piece 16b is a thin plate-shaped portion that is formed integrally with the mounting portion 16a, and whose tip is divided into two parts and is formed in a U-shape. The U-shaped locking piece 16b 14b is provided so as to protrude outward from 14b. A stepped recess 26 is formed at the tip of the U-shaped portion of the locking piece 16b.

  The female side connecting member 18 is a thin plate member made of synthetic resin or the like, and the thickness y thereof is set to be the same as or slightly larger than the thickness a on the outer peripheral side 14c side of the frame component 14 (therefore, the female side connecting member). The depth of the female side connecting member mounting recess 22 to which 18 is attached is approximately equal to or slightly deeper than the thickness y of the female side connecting member 18).

  An insertion groove 28 is formed on the end surface of the female side connection member 18 on the side of the connection side short side 14d, and the locking piece 16b of the male side connection member 16 described above is inserted into the insertion groove 28. Therefore, the locking side 16b is thinner than the thickness y of the female side connecting member 18, and is set to a thickness that can be inserted into the insertion groove 28 (approximately equal or slightly thinner).

  A U-shaped lower slit 18 a that communicates with the insertion groove 28 is formed on the lower surface of the female-side connecting member 18 (the surface that becomes the bottom surface of the frame component 12). A portion surrounded by the slit 18 a is a lock release piece 30. The lock release piece 30 is formed at a position where it comes into contact with an elastic engagement piece 32 to be described later when the lock release piece 30 is pushed up.

  Two large and small U-shaped upper slits 18b and 18c (large diameter upper slit 18b and small diameter upper slit 18c communicating with the insertion groove 28 are formed on the upper surface of the female side connecting member 18, and the upper sides of the two large and small The U-shaped portion surrounded by the slits 18 b and 18 c is the elastic engagement piece 32.

  The elastic engagement piece 32 is for preventing the male side connecting member 16 inserted into the insertion groove 28 from falling off the insertion groove 28, and its inner side surface (surface facing the insertion groove 28). In addition, an engaging protrusion 32a is formed that fits into and engages with the stepped recess 26 of the locking piece 16b of the male coupling member 16.

  The male-side connecting member 16 and the female-side connecting member 18 function as “connecting means” for connecting the frame constituent members 12 to each other. As such connecting means, in this embodiment, the YKK stock A company-made thin buckle (trade name: ZB25T, actual fairness 7-85) is used.

  When forming the frame member 10 for laying tatami using the frame constituent material 12 configured as described above, first, the laying tatami A laid on the floor surface (in this embodiment, four laying tatami mats A). Four frame members 12 (12a to 12d) are arranged around the tatami mat A (which is arranged in a square shape in two rows and two rows) (see FIG. 4).

  Then, the locking piece 16b of the male side connecting member 16 of one frame constituent member 12a is inserted into the insertion groove 28 of the female side connecting member 18 of the adjacent frame constituent member 12b (see FIG. 5). When the locking piece 16b is inserted all the way into the insertion groove 28, the engagement protrusion 32a of the elastic engagement piece 32 is fitted into the step-shaped recess 26, whereby the male side connecting member 16 is pulled out (from the insertion groove 28). Movement in the direction of detachment is restricted (see FIGS. 6 to 8).

  This operation is similarly performed for the other frame constituent members 12 (12b to 12d), whereby the rectangular frame-shaped laying tatami frame member 10 is completed, and the periphery of the laying tatami mat A is a laying tatami frame. It will be surrounded by the member 10.

  In the state where the male side connecting member 16 and the female side connecting member 18 are connected, as described above, the engaging protrusion 32a fits into the stepped recess 26 and the male side connecting member 16 moves in the pulling direction. It is regulated, and thereby a retaining effect can be obtained.

  On the other hand, when it is necessary to disassemble the laying tatami frame member 10, the laying tatami frame member 10 is lifted, and the lock release piece 30 of the female connection member 18 is pushed up with a finger. Then, the lock release piece 30 pushes the elastic engagement piece 32 upward (FIG. 8), and the engagement protrusion 32 a that has been fitted into the stepped recess 26 until then is released from the stepped recess 26. Thereby, the engagement state of the engagement protrusion 32a and the stepped recess 26 is released, and the male side connection member 16 can be pulled out from the female side connection member 18. And the frame member 10 for laying tatami can be easily disassembled by performing said operation in all the connection parts.

  As described above, according to the frame member 10 for laying tatami of this embodiment, when the frame constituent members 12 are connected to each other, the engagement protrusion of the male side connecting member 16 in one frame constituent member 12a. The frame constituent members 12 can be connected to each other by a simple operation of inserting the portion 32a into the insertion groove 28 of the female side connecting member 18 in the other frame constituent member 12b.

  On the other hand, when disassembling the frame constituent members 12 that are connected to each other, the lock release piece 30 of the female side connecting member 18 in the other frame constituent member 12b is pushed up to engage the stepped recess 26 and the engaging protrusion 32a. Release the combined state. Then, if the locking piece 16b of the male side connecting member 16 of the one frame constituent member 12a is pulled out from the insertion groove 28 of the female side connecting member 18 of the other frame constituent member 12b, the two frame constitutions that have been connected are connected. The materials 12a and 12b can be easily disassembled.

  Thus, according to the frame member 10 for laying tatami of a present Example, the connection and disassembly operation | work of the frame structural members 12 which comprise this can be performed very simply.

  Further, the male side connecting member 16 and the female side connecting member 18 constituting the connecting means are each configured to have a thin wall shape of about several millimeters, and a thickness like that of a conventional twisted tablet is required for the attachment. Therefore, it is possible to provide a frame member 10 for a laying tatami mat for a thin laying tatami mat A.
