Abstract

<P>PROBLEM TO BE SOLVED: To provide a clearance blocking device of an opening and closing body capable of forming a structure generating no noise even if the opening and closing body is vigorously closed. <P>SOLUTION: Even if a sliding door P is vigorously abutted against a stop column R to close by moving the sliding door P, when a rod 8 of a detection body 3 and a movable piece 7 are moved against energizing force of a spring 9, since such a movement receives resistance force of high viscous fluid influenced on the rotation of a pinion 5a and resistance force resulting from the engagement of the pinion 5a with a rotational rack 8a, a velocity of the movement is lowered, and the front end section in a projected state slowly retreats into a cover 5 of the detection body 3. In accordance with such a retreat, a notch groove 7a<SB>1</SB>of the movable piece 7 as a non-magnetism section is moved to a position (predetermined position) facing a magnetic body 4d of a blocking body 4, and since the blocking body 4 is slowly oscillated with the hinge piece 4c as the axis to hang down on a sill Q with the result that gravity acting on the blocking body is gradually getting higher than magnetic force from the detection body 3, the closing body 4 is rapidly hung down to prevent it from being abutted on the lower frame Q. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention, when the opening / closing body is closed, between the lower end of the opening / closing body and the lower frame or floor of the opening / closing body and / or between the upper end of the opening / closing body and the upper frame of the opening / closing body. The present invention relates to a gap closing device that closes a generated gap.

2. Description of the Related Art There are various types of devices that are attached to an opening / closing body and that close a gap formed between, for example, the lower end of the opening / closing body and the lower frame or floor surface of the opening / closing body when the opening / closing body is closed. .
As shown in FIG. 7, the airtight structure of the door disclosed in Patent Document 1 is such that an upper bar magnet 101 in which N poles and S poles are alternately formed in the longitudinal direction is slid in the lateral direction of the door 100. A contact bar 103 which is housed in a movable manner and is biased at one end of the upper bar magnet 101 by a spring 102 and connected to the other end is projected and retracted laterally from the lower side of the door 100, A hermetic packing 104 is housed under the upper bar magnet 101 so as to protrude and retract from the lower surface of the door 100, and a lower bar magnet 105 having N poles and S poles alternately formed in the longitudinal direction on the upper surface of the hermetic packing 104. The upper bar magnet 101 and the lower bar magnet 105 are mounted in the same manner as the magnet 101 in the state where the door 100 is closed and the contact bar 103 is pressed against the inner surface of the door frame 106 and retracted from the side of the door 100. By facing the poles together The airtight packing 104 is protruded from the lower surface of the door 100 by a repulsive force so that the airtight packing 104 is pressed against the lower surface of the door frame 106, the door 100 is opened, and the contact bar 103 is separated from the inner side surface of the door frame 106. In this state, the upper bar magnet 101 and the lower bar magnet 105 are opposed to each other with the opposite poles facing each other so that the airtight packing 104 is retracted from the lower surface of the door 100 by an attractive force. FIG. 7A is a structural view of a door to which a conventional device is attached, and FIG. 7B is a cross-sectional view of the conventional device.

However, in the above-described door hermetic structure, when the hermetic packing is protruded from the lower surface of the door by the repulsive force caused by facing the upper bar magnet and the lower bar magnet with the same polarity, the lower surface of the door frame is pressed. When the door is closed, the contact bar is pressed against the door frame. When the door is closed, the contact bar is pressed against the inner surface of the door frame. At this time, the hermetic packing descends suddenly and hits the lower surface of the door frame to generate noise, resulting in discomfort. Further, if this is repeated, the airtight packing and the lower surface of the door frame may be damaged, and the intended purpose of the airtight structure cannot be achieved.
Furthermore, in the case of the type of door that moves the lower frame, with the above-described airtight structure of the door, when the door is closed moderately or when the door is closed vigorously, the impact is generated between the door and the door frame. There may be a gap, and at this time, the opposite faces of the same poles will be misaligned, and the repulsive force will not be obtained sufficiently. As a result, the hermetic packing cannot be pressed against the lower surface of the door frame. Since a gap is formed between the lower surface of the frame, for example, cooling and heating are not effective and uncomfortable feeling occurs.

Further, the closing body 23 is attracted to the plate piece 32 of the first operating body 25 by the magnetic body 23d of the closing body 23. Therefore, as shown in FIG. 5 (B), the lower end of the sliding door P and the bottom of the sliding door There is a gap between the frame Q.

  However, when the sliding door P is further moved in the direction of the arrow in FIG. 5B to close the sliding door P in contact with the door stop column R (corresponding to releasing the set state), first, the second A portion of the operating body 29 that protrudes from the above-described detection body 22 abuts on a locking member 33 provided on the lower frame Q of the sliding door. By this contact, the second operating body 29 rotates about the pin 29b of the second operating body 29, and the locking member 33 is fitted into the concave groove 29a of the second operating body 29 almost simultaneously with the start of the rotation. On the other hand, since the protrusion 29c of the second operating body 29 is detached from the lateral groove 27a of the detection body 22 and moves to the vertical groove 27b of the detection body 22, the compressed spring 30 is extended. However, since the locking member 33 is fitted in the concave groove 29a of the second operating body 29 and the second operating body 29 is stopped at the position of the locking member 33 (therefore, the first operating body 28 is also stopped at the position). In addition, due to the extension of the spring 30, the detection body 22 moves in the direction of the arrow in FIG. 5B along with the relative movement of the protrusion 29 c along the longitudinal groove 27 b, and accordingly, the sliding door P Also move in the same direction. And since the movement of this sliding door P can implement | achieve the effect that the sliding door P itself self-propels and closes naturally on the external appearance, it can improve a user's convenience.

Further, in the present embodiment, since the same suppression mechanism 24 as that in the above-described embodiment is provided, the relative movement of the protrusion 29c along the vertical groove 27b, that is, the movement of the detection body 22 in the arrow direction is performed. However, since the resistance force of the highly viscous fluid exerted on the rotation of the pinion 24a and the resistance force due to the engagement between the pinion 24a and the rack 22a are received, the speed of the movement is reduced and the sliding door P can be closed slowly. With such movement, the adsorption is released as the plate piece 32 of the first operating body 28 gradually stops confronting the magnetic body 23d of the closing body 23, and the attraction force exerted on the closing body 23 gradually decreases. below, the closure body 23, the flange 23b, the bent portion _23b 1, 23c ₁ and 23c are slowly moves downward along the side inner wall 21b, 21c of the case body 21, the inner wall 21b, the lowermost end of 21c Since it is respectively hooked on the hook portion provided on the sliding door, it does not droop drastically when it hangs down on the lower frame Q of the sliding door. Therefore, the lower end portion of the sliding door P and the bottom of the sliding door without generating noise. A gap generated between the frame Q and the frame Q can be closed (see FIG. 6B). In addition, since the moving speed of the sliding door P is relieved, it cannot be overemphasized that the noise between the sliding door P and the door stop pillar R can also be eliminated.

  By the way, as a method for the sliding door P itself to self-run and naturally close, in addition to the present embodiment, for example, a method of tilting a guide member (rail) obliquely to the upper frame, a method using a mainspring spring, a method using a gravity hinge and so on.

  The gap closing device of the present invention has an advantage that no noise is generated even if the opening and closing body is closed forcefully, and since the opening and closing body itself is configured to be self-propelled and closed naturally, it can prevent forgetting to close. Use such as that there is no gap between the lower end of the opening and closing body and the lower frame or floor of the opening and closing body and / or the upper end of the opening and closing body and the upper frame of the opening and closing body. It can be said that the product value is high considering the convenience of the user without causing discomfort to the user.
