Japanese Patent No. 3145645

As described above, in the door described in Patent Document 1, since the slider and the arm stopper are engaged on the upper side of the upper side of the door body, when the door is attached to the entrance of a bathroom or the like, the recess of the slider The position cannot be visually recognized. For this reason, there is a problem that the protrusion must be engaged with the position of the concave portion by groping and the door mounting workability is poor.
An object of the present invention is to provide a door that can improve the mounting workability.

The present invention is provided between a door frame, a door main body attached to the door frame by a hinge so as to be opened and closed, and the door frame and the door main body, and for restricting the opening degree of the door main body. And a groove portion extending in a side direction is provided on the upper side of the door main body, and the restriction member includes a slider that slides along the groove portion, the door frame, and the slider. An arm stopper that connects to the door frame, the arm stopper is rotatably attached to the door frame, and a pin protruding downward is provided on the distal end side of the arm stopper. has an opening at the position of the door end side, a slider body accommodating hole for out allows housed is formed the pin forms a larger dimension than the outer diameter of the pin in the axial direction of the pin, said pin Characterized in that it comprises an introduction section for introducing the pin by expanding the opening into the receiving hole by the force of the Tsumoto side is applied from.

According to the present invention, after the slider is disposed on the suspension side, the protrusion provided on the distal end side of the arm stopper is fitted into the groove, and in this state, when the door body is opened, the proximal end attached to the door frame Since the arm stopper rotates about the side, the protrusion provided on the distal end side of the arm stopper moves to the suspension base side, and the pin comes into contact with the open portion of the slider body. When the door main body is further opened, a large force is applied to the suspension base side with respect to the introduction portion so that the pin in contact with the opening portion further moves toward the suspension base side, and the pin is stored in the storage hole. Therefore, the slider can be easily engaged with the front end of the arm stopper by simply opening the door body after placing the slider on the suspension side and the pin in the groove, without having to manually position the slider. It is possible to improve door installation workability.
Also, housing holes of the slider pin is housed, so capable out the pin no dimensions larger than the outside diameter of the pin in the axial direction, even in the case of emergency, removing the pins easily upward of the housing bore Thus, the door body can be easily removed from the door frame.

The introduction part is constituted by a pair of projecting pieces projecting so that the interval gradually increases from the opening part toward the door end side. In the normal state, the pair of projecting pieces has a dimension of the opening part of the pin . The dimension may be smaller than the outer diameter, and may be configured to be deformable in directions away from each other in accordance with the force applied from the pin .
According to such a configuration, when the door body is opened, the protrusion moves toward the suspension base, and the moved pin is guided toward the opening portion by the expanded portion of the pair of protruding pieces. When the door body is further opened, a large force is applied from the pin to the pair of projecting pieces toward the suspension base, so that the pair of projecting pieces are deformed to increase the size of the opening, and the pin is stored in the storage hole. The For this reason, engagement with the front end side of a slider and an arm stopper is realizable with a comparatively simple structure.

In the door described above, a notch that extends in the circumferential direction is formed on the outer periphery of the end of the pin on the arm stopper side, and the slider body has a door end side on the suspension side portion of the storage hole. It is possible to adopt a configuration in which a protruding flange portion that can be engaged with the notch portion of the pin is formed. When the door body is fully opened, a force is applied to the pin toward the suspension base, and the pin moves diagonally upward. Since the notch portion of the pin is engaged, it is possible to prevent the pin from coming out to the upper side of the storage hole.

  According to the door of this invention, there exists an effect that the workability | operativity of a door can be improved.

Hereinafter, a door according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an appearance of a door 1 according to the present embodiment. The door 1 is attached to, for example, a bathroom doorway, and as shown in FIG. 1, a door frame 10 having an upper frame 11, a lower frame 12, and left and right vertical frames 13, and a hinge 26 to the door frame 10. A door main body 20 that is freely opened and closed, and a regulating member 30 that is provided between the door frame 10 and the door main body 20 and regulates the opening degree of the door main body 20 are provided.

The door main body 20 includes a housing 24 in which an upper housing 21, a lower housing 22, and left and right vertical housings 23 are framed in four directions, and a face member 25 incorporated inside the housing 24. A groove portion 21 </ b> A extending in the side direction is formed on the upper surface of the upper collar 21. A handle 27 is attached to the vertical rod 23 on the door end side.
The hinge 26 is provided on the upper side of the vertical rod 23 on the suspension side, and pivots (not shown) from the small hole side of the vertical rod 23 with respect to a shaft hole (not shown) formed in the upper frame 11 of the door frame 10. The engagement state of the hinge 26 with respect to the door frame 10 is released by the advance and retreat of the pivot. For this reason, for example, even when the bather in the bathroom falls down with the key of the door body 20 hooked from the inside of the bathroom, the pivot is operated to engage the hinge 26 with the door frame 10. By releasing the state, the door body 20 can be removed from the door frame 10 to rescue the bather in the bathroom.

  FIG. 2 is an enlarged plan view showing the regulating member 30. As shown in FIG. 2, the regulating member 30 includes a slider 31 that slides along the groove portion 21 </ b> A formed in the upper collar 21, and a slider stopper 32 that is fixed at a position closer to the suspension side than the slider 31 in the groove portion 21 </ b> A. And an arm stopper 33 for connecting the door frame 10 side and the slider 31 to each other.

FIG. 3 is a longitudinal sectional view showing the arm stopper 33. As shown in FIG. 3, the arm stopper 33, the arm body 34 for example made of metal is elongated, the slider 31 protrudes downward from the distal end side S of the arm body 34 Lupi match the engagement (FIG. 2) down 35 and a mounting plate 41 that rotatably attaches the proximal end T of the arm main body 34 to the lower surface of the upper frame 11. A cutout portion 35 </ b> A extending in the circumferential direction is formed on the outer periphery of the end portion of the pin 35 on the arm main body 34 side (upper side).

  According to the above configuration, since the base end side T of the arm stopper 33 is rotatably attached to the door frame 10, when the door body 20 is opened in the direction of the arrow X shown in FIG. Rotate in the same direction. For this reason, the slider 31 that engages with the pin 35 of the arm stopper 33 moves to the suspension base side of the door body 20, and the slider 31 hits the slider stopper 32 to restrict the movement to the suspension base side. The opening of 20 is limited. When the door body 20 is closed in the direction of arrow Y in FIG. 2, the slider 31 moves to the door end side of the door body 20 together with the pin 35.

FIG. 4 is a plan view showing the slider 31. The slider 31 is a member made of, for example, resin or the like. As shown in FIG. 4, the slider 31 accommodates the pin 35 (FIG. 3) from the opening P on the door end side (right side in FIG. 4). A slider main body 36 in which a hole 36A is formed, and a pair of projecting pieces 38 extending in a tapered shape from the opening portion P to the door end side are provided. The pair of projecting pieces 38 are formed in a taper shape projecting so that the distance gradually increases from the opening portion P toward the door end side. Normally, the dimension of the opening portion P is smaller than the outer diameter of the pin 35. Thus, the member can be deformed in a direction away from each other according to the force applied from the pin 35.
As will be described later, when the slider 31 and the arm stopper 33 are connected, the pair of protruding pieces 38 are elastically deformed and released by the force from the pin 35 that has moved to the suspension side (left side in FIG. 4). The portion P expands, and the pin 35 is introduced from the expanded open portion P into the storage hole 36A.

  Since the storage hole 36A formed in the slider body 36 is formed with a size larger than the outer diameter of the pin 35, the pin 35 can be taken in and out in the vertical direction. For this reason, even in the case of an emergency described above, the pin 35 can be easily removed above the accommodation hole 36A.

  FIG. 5 is an enlarged longitudinal sectional view schematically showing a joint portion between the slider 31 and the arm stopper 33 constituting the regulating member 30. As shown in FIG. 5, in the slider main body 36, the notch formed in the pin 35 protrudes toward the door end side (right side in FIG. 5) on the suspension base side (left side in FIG. 5) of the storage hole 36 </ b> A. A flange portion 36B that can be engaged with the portion 35A is formed. The roles of the cutout portion 35A and the collar portion 36B will be described later.

Next, a procedure for attaching the door 1 of the present embodiment to an entrance of a bathroom or the like will be described.
FIG. 6 is an enlarged plan view showing the regulating member 30 and shows a state where the pin 35 and the slider 31 are not engaged before the arm stopper 33 is attached.
First, after attaching the door frame 10 to the entrance / exit of a bathroom or the like, the door body 20 is attached to the door frame 10 by engaging the pivot of the hinge 26 with the shaft hole of the upper frame 11. Subsequently, the attachment plate 41 of the arm stopper 33 is attached to the lower surface of the upper frame 11. A slider stopper 32 is fixed in advance in the groove portion 21 </ b> A of the upper collar 21, and the slider 31 is disposed closer to the door end than the slider stopper 32.

  Next, after the slider 31 is moved to the vicinity of the slider stopper 32, the pin 35 provided on the distal end side S of the arm body 34 is fitted into the groove portion 21 </ b> A of the upper collar 21. In this state, as shown in FIG. 6, the slider 31 is positioned closer to the suspending side than the pin 35. In this state, when the door body 20 is opened as shown by an arrow X in FIG. 6, the pin 35 moves from the door end side toward the suspension side, and when the pin 35 contacts the taper portion of the slider 31, A force toward the suspension base acts on the slider 31 from 35.

Then, since the movement of the slider 31 toward the suspension base is regulated by the slider stopper 32, when the door body 20 is further opened in the direction of the arrow X from this state, the pin 35 moves toward the suspension base, that is, the slider 31 side. Further, a large force acts on the root portions of the pair of protruding pieces 38 in an attempt to move. For this reason, the pair of projecting pieces 38 are elastically deformed in a direction away from each other, the opening portion P expands, and the pin 35 passes through the opening portion P and is stored in the storage hole 36A. When the pin 35 is stored in the storage hole 36A, the pair of protruding pieces 38 return to the normal state, so that the pin 35 does not come out of the storage hole 36A in the direction of the door end. Thereby, the pin 35 and the slider 31 are engaged, and the slider 31 engaged with the pin 35 can slide in both directions along the groove 21A.
In this way, by connecting the regulating member 30 between the door frame 10 and the door main body 20, the mounting operation of the door 1 is completed.

  Further, when the door body 20 is fully opened until the opening degree of the door body 20 is regulated by the regulating member 30, a large force from the arm stopper 33 to the upper end portion of the pin 35 acts on the suspension base side. A force acts to be pulled out obliquely upward (direction between the suspension base side and the upper side). On the other hand, in this embodiment, as shown in FIG. 7, it is possible to prevent the pin 35 from coming out above the accommodation hole 36A by engaging the flange portion 36B and the notch portion 35A.

  On the other hand, when it is desired to remove the door body 20 from the door frame 10 as in the above-described emergency, the engagement state between the cutout portion 35A and the collar portion 36B is released as shown in FIG. The regulating member 30 can be easily removed by pulling upward.

According to the present embodiment described above, the pin 35 is disposed in the groove portion 21A with the slider 31 brought close to the suspension side, and the operation of opening the door main body 20 is performed, so that the housing hole 36A and the pin 35 of the slider 31 are provided. The pin 35 on the distal end side S of the arm stopper 33 and the slider 31 can be easily engaged with each other without performing a position alignment by, for example, and the workability of attaching the door 1 can be improved.
Moreover, since the taper-shaped part was formed in a pair of protrusion piece 38, the pin 35 which has moved to the suspension base side can be smoothly guide | induced to the vicinity of the open part P. FIG.
Further, since the storage hole 36A is formed with a size larger than the outer diameter of the pin 35 from above, the engagement between the slider 31 and the pin 35 can be easily released even in the case of an emergency described above. The door main body 20 can be easily removed from 10.

The present invention is not limited to the embodiment. In the above-described embodiment, the notch 35A is formed on the upper side of the pin 35, and the flange 36B is formed on the slider main body 36. By engaging the collar 36B and the notch 35A, the pin is formed from above the accommodation hole 36A. 35 is prevented from coming out, for example, by adopting a configuration in which a collar portion is formed on the suspension base side of the outer periphery of the pin 35 and this collar portion engages with the periphery of the storage hole 36A in the slider body 36. The pin 35 may be prevented from coming out from above the storage hole 36A. In short, the configuration is not particularly limited as long as the pin 35 can be prevented from coming off from above the storage hole 36A.
In the above embodiment, the introduction member is configured as a pair of projecting pieces 38 projecting from the slider main body 36. However, the introduction member may be configured using a leaf spring or the like, and the configuration of the introduction member is not particularly limited.
