JP5312245B2 - Device for preventing accidents such as pinching of fingers in automatic doors - Google Patents

Description

  The present invention relates to a pinch accident prevention apparatus for fingers and the like in a sliding door type automatic opening / closing door.

The inventor of the present application has proposed Japanese Patent Application No. 2009-092575 as this kind of accident prevention apparatus.
The contents are a vertical or a head with a concave slope that separates the fingers touching the door side of the door pocket from the door, and a detection sensor that stops or reverses the door movement by detecting the tentacles behind the concave slope. It is described.

Japanese Patent Application No. 2009-092575

  However, the above-mentioned head is effective because the gap between the door and the vertical or door pocket is so narrow that it is in contact with a single-sided door frame with the glass surface of the door having a Γ-shaped cross section. In a door that surrounds a glass surface with a door frame having a U-shaped cross section, there is a problem that the gap is widened in the wing piece of the door frame, which is not appropriate.

  The present invention includes an adjustment mounting member that can be fixed by being shifted to the vertical or the like even when a gap between the door and the vertical or door pocket is wide depending on the type of the door, etc., and fitted to the adjustment mounting member This is a problem with a projecting part with an outer concave slope that is configured with a buffer member, narrows the gap until it is close, and jumps away the finger touched to the gap side of the buffer member from the gap. It was made to solve.

  Since the present invention is configured with an adjustment mounting member that is positioned and fixed in a vertical or the like, and a buffer member that is fitted to the adjustment mounting member, the wide gap is naturally a gap corresponding to the size of the gap. It is possible to shift and attach so as to narrow the gap, and it is possible to surely prevent a pinching accident.

  Since the projecting portion including the outer concave slope is subjected to a sliding process, there is an effect that even if it is a tentacle or pinched, it slips through and does not cause an accident.

(A) is a partially enlarged cross-sectional plan view when the adjustment mounting member of the device of the present invention is positioned and fixed with a screw on the side facing the automatic opening / closing door, and (b) is a cushioning member that is decorated with a cover. The figure which shows the state which fitted The top view which shows the state where the finger etc. which touched the automatic opening and closing door slip off the glass surface by sliding on the outer dent slope Same as above, a plan view showing the situation where a finger accidentally caught in a gap is easily removed (A) is a partially enlarged cross-sectional plan view showing an embodiment in which the device of the present invention is provided at both the inside and outside entrances across the door of the door pocket, (b) is between the vertical and glass surfaces and between the vertical and opening direction side. Partially enlarged transverse plan view showing an embodiment provided with the device of the present invention between each door frame In the second embodiment, (a) is a cross-sectional plan view in which a linear switch is wired in the cavity of the buffer member, (b) is a plan view showing a state in which the linear switch is operated by a tentacle, and (c) is a plan view. Similarly, a plan view showing a state in which a linear switch is activated by deforming an outer dent slope with a finger or the like entering a gap

Since the present invention is configured with the adjustment mounting member that is positioned and fixed to the vertical or door pocket according to the size of the gap and the buffer member that is fitted to the fitting portion of the adjustment mounting member, the wide gap is also approached. Protrusions with an outer dent slope that can be narrowed and the fingers touched to the gap side of the cushioning member bounce away from the gap are provided with a sliding process, so it is likely to be drawn into the gap by the tentacles The fingers were pinched by slipping and jumping along the outer dent slope to prevent accidents.
Moreover, since the inside of the buffer member is made hollow and an emergency linear switch that is operated by a tentacle to stop or return is provided, accidents can be prevented from being caught at an early stage, thereby improving safety. I was able to do that.

  A gap K between the sliding door type automatic opening / closing door 3 formed of the glass surface 2 surrounded by the door frame 1 having a U-shaped cross section and the storage frame or door pocket 4 is widened by the thickness of the door frame 1.

  The vertical or door pocket 4 is installed vertically in the direction of the gap K in the doorway 3 of the door 3. First, the adjustment mounting member 5 is positioned in consideration of the gap K, fixed with a screw 5a, and decorated with a cover 5b. The adjustment mounting member 5 may be fixed with a double-sided tape or an adhesive instead of the screw 5a.

  Next, the fitting portion 6 a of the buffer member 6 is fitted and attached to the fitting portion 5 c of the adjustment mounting member 5. The outer end of the buffer member 6 fills the gap K and approaches the glass surface 2. Further, the outer end of the buffer member 6 has a protruding portion 6b protruding in the door closing direction and an outer concave slope 6c on the fitting side from the tip. In addition, the glass surface 2 side of the protrusion part 6b is a flat surface.

  The glass surface 2 side of the protrusion 6b and the surface of the outer dent slope 6c are subjected to a sliding process with silicone or fluorine. The buffer member 6 has a hollow inside its entire length.

  Then, when the automatic opening / closing door 3 opens and enters the room, if the finger accidentally touches the glass surface 2 and is about to be pulled up or drawn into the doorway of the door pocket 4 as shown in FIG. In this case, the outer recessed slope 6c is slid from the top of the protrusion 6b of the buffer member 6 and is not drawn or pinched by being separated from the gap K. In the unlikely event that a small finger such as a child is drawn into the gap K side, it is shown in FIG. 3 because it is slipped and spreads by being recessed toward the internal cavity. So that it does not progress into an accident.

  When the device of the present invention is attached as shown in FIG. 4 (a) when going out of the room, the same safety as when entering is taken. Further, as shown in FIG. 4B, the device of the present invention is also attached to the door frame 1 on the door opening direction side, so that fingers or the like are not caught in the gap K between the door frame 1 that moves open and the vertical frame 4. Sometimes it does.

  FIG. 5 shows a second embodiment in which an emergency linear switch 7 is wired in the cavity 6d in the buffer member 6 as shown in FIG. The door 3 is stopped or returned and closed when it is sensed by touching 6c. When the finger is drawn into the gap K, the linear switch 7 is similarly operated by the deformation pressure of the buffer member 6 so that the accident does not proceed as shown in FIG. Other configurations and operations are the same as in the previous example.

  The present invention is configured with an adjustment mounting member that is shifted and mounted in accordance with the width of the gap, and a buffer member that is fitted to the gap even when the gap between the vertical or door and the automatic opening / closing door is wide depending on the type of the door Therefore, it is widely used because it can be attached to all.
