JP 2001-323719 A

  In the normally closed swing door as described above, when a person normally enters and exits, the door is pushed and abuts against a door contact member provided at the end of opening, and the door does not catch. It can be easily returned to the closed position.

  However, there are cases where it is desirable to catch the door in an open state, for example, when loading a package. A conventional swing door provided with a door stop member cannot catch in an open state, and a door provided with a catch member cannot catch the door and cannot be freed.

  An object of the present invention is to provide a swing door device that can freely select catching and non-catching of a door when opened in view of the above-described problems of the prior art.

According to the present invention, the above problem is solved as follows.
(1) In a swing door device in which one side end of a door body is pivotally attached to a side wall of a passage with a vertical pivot, a door stop member and a door catch member are attached to a holding member and held rotating the member, the end of the trajectory of the opening time of the door body in the side wall of the passage, a contact position of the doorstop member abuts said door body, to a retracted position away from the moving range of the door body The door catch member is pivotally supported with a horizontal pivot, and the door catch member cannot catch the door body when the door stop member is in the contact position, and the door stop member is in the retracted position. The door main body can be caught and the holding member is pivotally supported on the pivot so that the door-contacting member is rotated to a contact position by its own weight in a free state .

( 2 ) In the above item (1), the door catch member is magnetically caught.

( 3 ) In the above item (1) or (2) , the amount of protrusion from the side wall of the passage toward the door body is made larger for the door stop member than for the door catch member.

( 4 ) In any one of the above items (1) to ( 3 ), biasing means for biasing the door body to the normally closed position is provided on the support means of the door body.

According to the present invention, the following effects can be achieved.
(a) According to the invention of claim 1, the door stop member can be rotated between the contact position and the retracted position of the door body, and when the door stop member is in the contact position, the door body cannot be caught, By making the catch possible at the retracted position, the door catch and non-catch can be freely selected when the door is opened.
In addition, the door stop member can be easily moved to the retracted position and the contact position simply by rotating the holding member.
Furthermore, since the holding member is located at a position where the door stop member can come into contact with the door body due to its own weight, there is no need to reset the door stop member to the contact position, and only when it is desired to catch the door body. Since the holding member only needs to be rotated, the operability is good.

( b ) According to the invention described in claim 2 , since the door catch member is a magnet catch, the entire door can be held strongly by simply contacting the door catch member without being pressed against the door catch member, and at a low cost. Can be manufactured.

( c ) According to the invention described in claim 3 , the door main body can be easily brought into the non-catching state by the contact with the door contact member having a large protruding amount.

( d ) According to the invention of claim 4 , since the door body is urged to the normally closed position by the urging means, the door is automatically brought into the normally closed position after contacting the door stop member. The door catch member can be held only when the door stop member is in the retracted position.

Hereinafter, embodiments of the swing door device of the present invention will be described with reference to the drawings.
1 is a front view of a swing door device according to an embodiment of the present invention as seen from the passage entrance side, FIG. 2 is a side view taken in the direction of the arrow II in FIG. 1, and FIG. 4 is a side view similar to FIG. 2 when rotated to the retracted position, FIG. 4 is an enlarged side view of the door holding mechanism, and FIG. 5 is a cross-sectional view taken along line VV of FIG.

  As shown in FIG. 1, the left and right side walls (2) and (3) of the entrance / exit are constituted by a structure (1) such as a counter, and a pair of upper and lower support brackets (4) attached inside one side wall (2). The door body (8) is rotatably supported by the vertical pivots (6) and (7). Located between the support brackets (4) and (5), a door holding mechanism (9) is attached to the side surface of the side wall (2) on the passage side.

  As shown in FIGS. 2 to 5, the door holding mechanism (9) is configured by attaching a door stop member (11) and a door catch member (12) to a holding member (10). The holding member (10) has a substantially square or rhombus shape, and its upper part is pivotally attached to the side wall (2) with a horizontal shaft (13) made of a stepped screw. The door stop member (12) is made of a cushioning material such as rubber, and is fixed to the lower end portion of the holding member (10) with a set screw (14). The door catch member (12) is fixed to the holding member (10) with a set screw (15) between the door stop member (11) and the shaft (13). In the illustrated example, the door catch member (12) has a magnet (12a) embedded therein, and adsorbs the door body (8) made of a magnetic material. Note that the door catch member (11) may be a known member in which a protrusion projecting from the door body (8) is clamped and gripped by a pair of gripping pieces.

  The door holding mechanism (9) is normally in a state in which the door stop member (11) is positioned at the lower end due to its own weight and the door catch member (12) is positioned above it. In this state, as shown in FIG. 2, the door stop member (11) is in a contact position with which the door body (8) contacts when opened. In this state, when the door body (8) is opened (the state of the chain line in FIGS. 1 and 2), the door body (8) comes into contact with the door stop member (11), and the door body (11) of the door stop member (11) ( 8) Since the protruding amount in the direction is larger than the door catch member (12), the door body (8) is in a non-catch state where it cannot be caught by the door catch member (12).

  If you want to catch the door body (8) and keep it in the normally open state, manually move the door holding mechanism (9) so that the door stop member (11) is in the retracted position retracted from the track of the door body (8). Therefore, it is rotated in the direction of the arrow in FIG. Thereby, as shown in FIG. 3, the door catch member (12) can catch the door body (8), and the door body (8) can be caught in the normally open state.

In the above embodiment SL, in order to attach the the doorstop member (11) Door catch member (12) and, together with the doorstop member (11) one of the holding member (10), the door catch member (12) However, the door catch member (12) may be fixed at a fixed position and only the door stop member (11) may be moved.

The door body (8), the pivot (6) (7) but may simply be a structure simply by pivotally mounted, as shown in FIG. 6, the biasing means may have a structure for supporting the normally closed position .
As shown in FIG. 8, the lower bracket (5) is attached with a support shaft (21) having an inclined cam surface (19) on the upper surface and a pivot (20) at the center thereof, and the door body (8). A bearing (23) having an inclined cam surface (22) complementary to the inclined cam surface (19) is attached to the lower surface. To install the door body (8), the upper bearing (24) is inserted into the upper pivot (6) attached to the upper bracket (4), and then the lower bearing (23) is inserted into the lower bearing (23). The upper and lower inclined cam surfaces (19) and (22) are engaged by being inserted into the pivot (20) and lowered.

  The state in which the both inclined cam surfaces (19) and (22) are completely matched is the normally closed state of the door body (8). When the door body (8) is pushed open, the inclined cam surface (22) of the bearing (23) rides on the inclined cam surface (19) of the support shaft (21), and the door body (8) moves slightly upward. However, when the pushing force is released, the door body (8) descends while rotating by its own weight, and returns to the original normally closed position. That is, the inclined cam surfaces (19) and (22) and the weight of the door main body (8) are urging means for urging the door main body (8) to the normally closed state.

  The biasing means for biasing the door body (8) to the normally closed position may be a known spring provided in the vicinity of the support portion of the door body (8) in addition to such a cam mechanism.

It is a front view seen from the passage entrance side of the swing door apparatus is implementation form of the present invention. Similarly, it is the II direction arrow side view of FIG. Similarly, it is a side view similar to FIG. 2 when the door stop member is rotated to the retracted position from the state of FIG. Similarly, it is an enlarged side view of a door holding mechanism. It is the VV sectional view taken on the line of FIG. It is a disassembled front view which shows an example of a door urging means.
