Description

  In the present invention, when the angle data and length data of a plurality of measurement points around the room are collected from the approximate center of the room by the room dimension measuring device, the height from the floor surface of the room to the upper surface of the sill at each measurement point. Relates to an apparatus configured to collect data.

  When manufacturing a tatami mat to match the shape of the room, the actual dimensions of the room are measured in advance, and the tatami mat is cut by numerical control or the like. Since the actual area of the room described as 4 tatami half, 6 tatami mat, 8 tatami mat and the like is not always the same, the actual dimension of the room is measured in advance, and the room The tatami mat is cut according to the shape.

  Conventionally, a room dimension measuring apparatus for measuring the actual dimension of a room has been proposed in Patent Document 1 and Patent Document 2 below. This room dimension measuring device measures and collects polar coordinate data consisting of length data and angle data up to the measurement points around the room to be measured with reference to a position near the center of a substantially rectangular room. This is a dimension measuring device for converting polar coordinate data into XY coordinate data suitable for tatami mat cutting, and expressing it. In addition, this measurement point is a measurement point determined by the inter-measuring measurement or the booth-measuring measurement.

  When a plurality of tatami mats are laid in a room, if the surface heights of adjacent tatami mats do not match, a step is produced at the mating portion of the tatami mats. In particular, in the tatami mat that touches the sill, if the upper surface of the sill does not coincide with the surface height of the tatami mat, a step is similarly generated in the abutting portion and the appearance is deteriorated.

  If there is no unevenness on the floor surface of the room, the surface height of the adjacent tatami mats will not be uneven, but there are many cases where a difference in level occurs because the upper surface of the sill does not match the surface height of the tatami mats.

  Therefore, in order to align the surface height of the mating part of the tatami mat and the sill without a step, in the manufacturing process, a spacer is inserted on the back surface of the mating part with the tatami sill for each tatami mat to make the tatami thickness fine. Adjustment has been made conventionally.

Japanese Patent No. 3659436 Japanese Patent No. 4250735

  In such a conventional room dimension measuring apparatus, the probe is brought into contact with each measurement point (see FIG. 5) of the room, angle data and length data for the measuring apparatus main body are collected in polar coordinates, and X- Although converted into Y coordinate data, there was no means for collecting height data from the floor surface to the sill top surface at each measurement point in the room.

  The tatami craftsman who sticks to the beauty of the appearance when laying in the room finely adjusts the thickness of the tatami mat so that the surface height of adjacent tatami mats matches the height of the tatami mat surface . In this fine adjustment method, one or a plurality of thickness adjusting materials (thickness of tape, paper, goza, etc.) are overlapped on the back surface of the tatami floor and adjusted to a desired thickness.

  Therefore, when laying in the room, the height from the floor surface to the top surface of the sill at each important point around the room is measured separately and written down. Based on this memo, The thickness of the abutting part (bottom front, heel) was finely adjusted.

  As described above, it takes time to measure the height from the floor surface to the upper surface of the sill for each important point in the entire periphery of the room, and many measurement and entry errors occur.

  When adjusting the thickness of the tatami mat, the thickness adjustment materials such as tape, paper, goza, etc. are selected and the number of them is adjusted and sewn. Measurement waste and material waste, measurement errors and entry errors must be avoided as much as possible.

  The room dimension measuring apparatus according to the present invention is installed in the center of the room and rotates while emitting a laser beam, and responds when the laser beam of the measuring apparatus body is received at a plurality of measurement points in the room. In a room dimension measuring apparatus comprising a probe, collecting position data of each measurement point in polar coordinates when the probe responds, and storing it in a storage means, the probe has a floor surface to a sill top surface. Sill height measuring means for measuring the height of the sill is provided, and the sill height data is transmitted to the main body of the measuring apparatus.

  According to the room dimension measuring apparatus of the present invention, when measuring the actual dimension of the room at each measurement point determined in the inter-measuring or booth measuring, the floor or the part where the heel hits the sill is measured on the floor. Since the height from the surface to the top of the sill can be measured mechanically, human errors such as measurement errors and transcription errors can be prevented. Therefore, the work of finely adjusting the thickness of the front of the tatami or the heel portion can be performed without error so that the upper surface of the sill matches the height of the tatami.

  Further, the measurement apparatus main body H includes the signal processing circuit shown in the block diagram of FIG. 2, and when the measurement apparatus main body H rotates and the laser beam 15 enters the optical sensor 42 of the probe 4. When the infrared LED is radiated from the response LED 43 and received by the optical sensor 16 of the main body, the angle data obtained by the rotary encoder 11 and the length data obtained by the linear encoder 13 are stored in the memory. The threshold height data modulated by the response infrared ray radiated by the probe 4 is also stored at the same time.

  In the present invention, as shown in the plan view (a) and perspective view (b) of FIG. 3, the height from the floor surface (the bottom surface of the probe 4) to the top surface of the sill is measured on the probe 4. A height measuring device is provided.
