2. Description of the Related Art A door frame is provided along an opening as an entrance of a bathroom, and a closing member such as a door is mounted in the door frame so that the door frame can be opened and closed. Then, a step is provided so that the upper surface of the lower frame of the door frame is sufficiently higher than the floor surface of the bathroom to prevent water in the bathroom from flowing out of the bathroom.

[0003]

However, if the height of the upper surface of the lower frame of the door frame is increased to provide a step, there is a possibility that the step may trip the foot, which is not preferable from the viewpoint of safety. is there. Therefore, the applicants of the present patent application have previously filed the one disclosed in Japanese Patent Application No. 8-285725 as ensuring the waterproof property even if the height of the upper surface of the lower frame portion of the door frame is lowered. In this, a water stop member that is long in the longitudinal direction of the lower frame is vertically attached to the lower frame of the entrance and exit, and when the door is closed by the door, the water stop member stands up and when the door is opened, the water stop member is installed. It is designed to be knocked down on the lower frame. However, in the prior application, since the opening and closing of the door and the raising and lowering of the water stop member are linked, a drive device is provided on the upper surface of the water stop member, and when the door is closed, the drive device is pushed by the door to raise the water stop member. There is a problem that the driving device having a high height and a large size is projected on the water stop member, and the appearance of the driving device is not good, and there is a risk of catching a foot on the driving device. there were.

The present invention has been made in view of the above-mentioned points, and it is an object of the present invention to provide a structure of a lower frame portion of an entrance / exit which does not have a bad external appearance and is not likely to be caught.

[0005]

In order to solve the above problems, the structure of the lower frame portion of the entrance / exit of the present invention is such that a water stop member 2 which is long in the longitudinal direction of the lower frame 1 is rotatably attached to the lower frame 1 of the entrance / exit. The water stop member 2 is pivotally supported so as to be able to move up and down, and when the doorway is closed by the closing member 3 such as a door 3a or a sliding door, the water stop member 2 is rotated in a direction away from the closing member 3 When the stopper member 2 is erected and the closing member 3 is opened, the water stopper member 2 is rotated in the direction of the closing member 3 by its own weight and laid down on the lower frame 1, which is orthogonal to the longitudinal direction of the lower frame 1. The lower frame 1 part is provided with an arm 5 for pushing the water stop member 2 so that the tip end side thereof rises obliquely upward and rises when the water stop member 2 slides in a direction approaching the pivotal support portion 4 of the water stop member 2. When the member 3 is closed, the trigger 6 pushed by the closing member 3 is attached to the lower frame 1 The lower frame 1 is provided at a position closer to the closing member 3 than the arm 5 so as to be slidable in the direction orthogonal to the longitudinal direction, and the trigger 6 and the arm 5 are interlocked between the trigger 6 and the drive. A return spring 8 is provided which interposes a spring 7 and pushes the arm 5 away from the pivotal support 4 of the water stop member 2 when the trigger 6 is not pressed. The constant is smaller than the spring constant of the driving spring 7. When the closing member 3 is closed, the trigger 6 is pushed and slides by the closing member 3, and the sliding of the trigger 6 pushes the arm 5 via the drive spring 7 so that the arm 5 resists the return spring 8. Then, the tip of the arm 5 is slid upward so that the tip of the arm 5 rises, and the water stop member 2 stands up at the tip of the arm 5. When the closing member 3 is opened, the pressing force of the trigger 6 is released and the trigger 6 slides away from the water stop member 2, and the arm 5 is moved by the spring force of the return spring 8.
The water stopper member 2 is slid in a direction away from the pivotal support portion 4 and is not pushed by the arm 5, so that the water stopper member 2 falls down. At this time, the arm 5 and the trigger 6 are hidden under the water stop member 2 so that the external appearance does not deteriorate and the foot is not caught. Further, even if the water stop member 2 is stepped up with the foot kept standing, the arm 5 slides against the spring force of the drive spring 7 and the water stop member 2 falls and the water stop member 2 There is no risk of damage. Further, when the water stop member 2 is erected, the arm 5 is moved by the trigger 6 via the drive spring 7.
Is pushed and the tip of the arm 5 is raised obliquely upward, so that the water stop member 2 is raised, so that the water stop member 2 can be stably raised for a long period of time, and the sliding stroke of the trigger 6 is increased. Even if it is small, the water stop member 2 can be erected.

When the closing member 3 such as the door 3a is closed and the arm 5 is slid so as to rise obliquely upward, the arm 5
It is also preferable that the tip of the above-mentioned device pushes the vicinity of the pivotal support portion 4 of the water stop member 2. In this case, the water stopper member 2 can be erected by making the sliding stroke of the trigger 6 as small as possible.

An opening serving as an entrance and exit is provided between 0 and the outside of the bathroom 11, and a door 3a such as a swing door is openably and closably attached to the opening as a closing member 3 of the opening. The lower frame 1 of the door frame provided along the opening is made of a metal such as aluminum, and the door 3a is positioned above the lower frame 1 with the door 3a closed. A water stop member 2 is arranged on the lower frame 1 at a position opposite to the bathroom 10 side of the lower frame 1 so as to extend in the longitudinal direction of the lower frame 1, and the water stop member 2 is attached to the lower frame 1. It is mounted so that it can be tilted up and down. That is, the lower frame 1 is provided with a pivot shaft portion 12 extending in the longitudinal direction, and the pivot support portion 4 provided in the edge portion of the water stop member 2 in the longitudinal direction is rotated by the pivot shaft portion 12. It is installed freely.
A water stop plate 13 is attached to the longitudinal end of the lower frame 1, and the water stop member 2 contacts the lower surface of the water stop plate 13 when the water stop member 2 is erected. The floor 10a of the bathroom 10 is provided with a concave groove 14, and a glazing channel 15 is attached to the opening of the upper surface of the concave groove 14. A drive device A for raising and lowering the water stop member 2 is embedded and attached to the lower frame 1.

This drive unit A is formed as shown in FIGS. 5, 6 and 7, and is composed of a casing 16, an arm 5, a trigger 6, a drive spring 7, a return spring 8 and the like. There is. The casing 16 has a trigger storage opening 17
A pair of arm storage openings 18 are provided, and sliding guide grooves 19 are provided on both side surfaces of the casing 16. The sliding guide groove 19 includes a horizontal guide groove 19a and an inclined guide groove 1.
9b and. The arms 5 are a set of two, and the bases of the arms 5 are integrally connected by a connecting portion 20. The two arms 5 are slidably inserted into the arm storage openings 18 of the casing 16, and the sliding pins 21 and 22 projecting from the side surfaces of the arms 5 are slidably mounted in the sliding guide grooves 19. There is. And the sliding pin 21 is the horizontal guide groove 1
9a, the sliding pin 22 slides along the inclined guide groove 19
It is designed to slide along b. The trigger 6 is formed by integrally providing a base portion 6b and a semi-cylindrical operation portion 6a, and the trigger 6 is slidably mounted in a trigger housing opening 17. A spring accommodating recess 23 is provided on the base side of the arm 5, and a drive spring 7 such as a coil spring is inserted into the spring accommodating recess 23 and projects from the base end of the arm 5 of the drive spring 7. The base part 6b of the trigger 6 at the end
Is in contact with. When the driving spring 7 is attached, the force of the driving spring 7 is not acting and the arm 5 is in a horizontally tilted state. A return spring 8 such as a coil spring is interposed between the connecting portion 20 of the arm 5 and the casing 16 so that the arm 5 slides toward the trigger 6 and falls down. Regarding the return spring 8 and the drive spring 7, the return spring 8 has a smaller spring constant than the drive spring 7. When the trigger 6 is pushed from the state shown in FIG. 7A, the arm 5 is pushed via the drive spring 7, and the arm 5 slides against the return spring 8. When the arm 5 slides, the slide pin 21 slides along the horizontal guide groove 19a, and the slide pin 22 slides along the inclined guide groove 19b. As shown in FIG. Slide the tip of the to rise diagonally upward. When the arm 5 is pushed downward in this state, the arm 5 slides and falls against the force of the driving spring 7 as shown in FIG. 7C.

When the door 3a is opened, the trigger 6 is not pushed as shown in FIG. 3, and the water stop member 2 is in a state of falling down by its own weight. When the door 3a is opened, the water stop member 2 is horizontally tilted, so that the water stop member 2 does not get caught on the foot when passing. When the door 3a is closed from this state, the trigger 6 is pushed by the door 3a.
When the trigger 6 is pushed, the arm 5 is pushed via the drive spring 7, and the arm 5 slides against the return spring 8. When the arm 5 slides, it slides toward the pivotal support 4 side so that the tip of the arm obliquely rises as described above. As a result, the vicinity of the pivot portion 4 of the water stop member 2 is pushed to rotate the water stop member 2, and the water stop member 2 stands up as shown in FIG. When the water stop member 2 stands up, it is possible to reliably prevent water from leaking from the bathroom 10 side. Even if the water stop member 2 is stepped on while the water stop member 2 is standing, the arm 5 slides against the drive spring 7 and falls, causing the water stop member 2 to fall horizontally and damaging the water stop member 2. Never. Further, when the water stop member 2 is raised, the arm 6 is pushed by the trigger 6 through the drive spring 7 and the tip of the arm 5 rises obliquely upward so that the water stop member 2 is raised. Can be stably erected for a long period of time, and the water stop member 2 can be erected due to the small sliding stroke of the trigger 6. At this time, since the tip of the arm 5 pushes the vicinity of the pivotal support portion 4 of the water stop member 2, the sliding stroke of the trigger 6 can be further reduced. When the door 3a is opened contrary to the above, the door 3a is separated from the trigger 6, the pressure of the trigger 6 is released, and the arm 5 and the trigger 6 are slid by the return spring 8 in the opposite direction, and the arm 5 moves. It falls and the water stop member 2 falls by its own weight.

Although the door 3a such as a swing door is described as the closing member 3 in the above-mentioned embodiment, the closing member 3 can be similarly implemented whether it is a sliding door or a folding door.

An arm that pushes up to raise the water stop member is provided on the lower frame part, and when the closing member is closed, the trigger pushed by the closing member is slidable in the direction orthogonal to the longitudinal direction of the lower frame. It is provided on the lower frame part at a position closer to the closing member than the arm, and a drive spring for interlocking the trigger and the arm is interposed between the trigger and the arm, and when the trigger is not pushed, the arm is removed from the pivotal support part of the water stop member. A return spring is provided to push the arm away from the arm and the spring constant of the return spring is made smaller than the spring constant of the drive spring.When closing the closing member, the trigger is pushed by the closing member. The arm slides and pushes the arm through the drive spring by the sliding of the trigger, the arm slides against the return spring, and the tip of the arm rises diagonally upward. The water stop member stands up,
When the closing member is opened, the trigger is released and the trigger slides away from the water stop member, and the spring force of the return spring causes the arm to slide away from the water stop member pivot. , The water stop member is not pushed by the arm so that the water stop member falls down, and the water stop member is surely waterproof when the closing member is closed and the water stop member is closed when the closing member is opened. Not only can it be fallen out of the way, but the arm and trigger etc. are hidden under the water stop member so that it does not look bad on the outside and it does not get caught on the way while passing. Even when the water stop member is stepped on with the feet upright, there is no risk that the arm slides against the spring force of the drive spring and the water stop member falls and the water stop member is damaged. Water stop member When standing up, the arm is pushed by the trigger via the drive spring and the tip of the arm rises diagonally upward so that the water stopping member stands up, so that the water stopping member can be stood up stably over a long period of time. Even if the sliding stroke of the trigger is small, the water stop member can be erected.

According to a second aspect of the present invention, when the closing member such as a door is closed and the arm slides obliquely upward, the tip of the arm pushes the vicinity of the pivotal support portion of the water stop member. Therefore, the sliding stroke of the trigger can be made as small as possible to raise the water stop member.
