Description

  The present invention relates to a blind built-in partition device that houses a blind between a pair of front and rear glass plates.

  A partition device with a built-in blind that houses a blind (so-called Venetian blind) between a pair of front and rear glass plates is known (for example, Patent Document 1).

  In the conventional partitioning device, a transmission mechanism using a timing belt is vertically installed in one of the left and right support columns that support the glass plate, and the driving wheel at the lower end of the timing belt has an outer periphery at the joint between the glass plates adjacent to the left and right. The driven wheel at the upper end of the timing belt is attached to one end of the rotating shaft for adjusting the inclination of the slat at the upper end of the blind. Therefore, the blind can be opened and closed by adjusting the inclination of the slats from one side of the partition device by rotating the operation wheel forward and backward with fingers.

Japanese Patent No. 4774801

  When using such a prior art, the transmission mechanism using the timing belt requires a large number of required parts, and the work for assembling the support column tends to be complicated, and the operation wheel arranged on the joint is not always easy to rotate. There was a problem that it was not easy to use. In addition, when opening and closing the blinds from both sides as well as from one side of the partitioning device, it is necessary to prepare a transmission mechanism using a timing belt for each side, and the overall configuration is further complicated. . Such a blind operation from both sides may be required for applications such as partitioning a room such as a hospital ICU (intensive care unit) or NICU (neonatal intensive care unit).

  Therefore, in view of the problems and circumstances of the prior art, the object of the present invention is to greatly simplify the overall configuration by using a flexible shaft, and to include a blind opening / closing operation from both sides. An object of the present invention is to provide a partition device with a built-in blind that can be easily used.

  The structure of the invention of claim 1 for achieving this object includes front and rear glass plates, blinds accommodated between the glass plates, and front and rear operation knobs mounted on the front and rear glass frames for each glass plate, respectively. The gist of the operation knob is to individually connect to both ends of the rotating shaft for adjusting the inclination of the blind slat via the flexible shaft.

  In addition, each operation knob can arrange | position to the same height position of the same direction side toward each glass frame while aligning a shape.

  The structure of the invention of claim 3 includes front and rear glass plates, a blind housed between the glass plates, and an operation knob attached to the surface of the glass frame for one glass plate, and the operation knob is a flexible shaft. The gist is to connect to one end of the rotating shaft for adjusting the inclination of the slat of the blind.

  Note that the flexible shaft can pass up and down the inside of a support column that supports the glass plate via a glass frame, and the support column can be formed with upper and lower cutouts for drawing the flexible shaft.

  According to the first aspect of the invention, the front and rear operation knobs are respectively connected to the rotating shaft for adjusting the inclination of the blind slats via the flexible shaft. Therefore, when each operation knob is rotated forward and backward with fingers, the rotating shaft can be rotated through the flexible shaft, and the blind slats can be adjusted to adjust the inclination of the blind slats from the both sides of the partition device. it can. In addition, the flexible shaft is only a single member as a whole, and the operation knob on the surface of the glass frame has good operability, so that good usability can be easily realized. The axis of rotation for adjusting the tilt of the slat is housed in the blind body at the top of the blind in parallel with each slat. The operation knob on the glass frame stands upright on the surface of the glass frame so that the operator Is positioned at a height that is easy to operate. Therefore, the flexible shaft can smoothly transmit the rotational torque from the operation knob to the rotation axis even though the height positions of the rotation axis and the operation knob are different and the respective axial directions are orthogonal to each other.

  Each operation knob can be operated with the same operation feeling from both sides of the partition device by arranging the shapes and arranging them at the same height position on the same direction side toward the front and rear glass frames.

  According to the configuration of the invention of claim 3, the operation knob is mounted only on one surface of the glass frames for the front and rear glass plates. Therefore, at this time, the blind can be opened and closed only from one side of the partition device.

  The flexible shaft can smoothly transmit the rotational torque between the operation knob having a different height position and the rotating shaft by passing vertically through the column supporting the glass frame. This is because the support column is generally formed in a rectangular tube shape with a small cross-sectional area, so that the possibility of harmful twisting in the flexible shaft can be minimized. However, it is preferable that the flexible shaft minimizes wasteful slack and slack in the middle when the operation knob and the rotary shaft are connected.

  The flexible shaft can be drawn into the support through upper and lower notches formed in the support. The upper notch is preferably formed on the blind side surface of the support so as to face the rotation shaft at the upper end of the blind, and a flexible shaft connected to the rotation shaft is preferably drawn linearly into the support. In addition, the lower notch is formed so as to be long upwards, including the position of the operation knob, with respect to the common corners on the blind side and operation knob side of the column, and the flexible shaft connected to the operation knob is diagonally upward It is preferable to draw it into the column while curving smoothly.
