Description

  The present invention relates to a water blocking block for preventing water from leaking into an adjacent room through an opening, and a fitting equipped with the water blocking block.

Currently, so-called barrier-free interiors are being promoted to ensure safety in daily life at home.
This safety design concept has been incorporated into, for example, unit baths and ordinary household bathrooms. For example, if the bathroom and the changing room adjacent to it are made barrier-free, there will be a step between the two rooms. Therefore, even if you close the bathroom door and seal it with a water-stopping material attached to the door opening frame, for example, an adult may enter the fully-filled bathtub vigorously. If it does, water will flow out to the changing room side from the slight clearance gap of the water stop material.

Therefore, conventionally, for example, a tight material is disposed on the floor between the bathroom and the changing room, and the tight material is brought into contact with the outdoor side surface of the closed door basket so that the bathroom door has a lower end surface and the floor. The waterstop is attached to the vertical frame, and a tight material, i.e., a waterstop, is attached to the waterstop attachment so that both waterstops come into contact with each other. In a state where the door is closed, the door is closed with a water-stopping material so that water does not leak from the bathroom side to the changing room side.
However, at the joint corner between the vertical frame and the lower frame, the water-stopping material of the vertical frame and the water-stopping material of the lower frame are merely joined together, and are not integrated. Therefore, there is a problem that water easily leaks out, and therefore, it is difficult to stop the water at this portion. For this reason, as a measure against water stoppage at this portion, a material using an auxiliary tight material at the joint lower corner portion in addition to the both waterstop materials is known (see Patent Document 1).
That is, as shown in FIG. 10, the auxiliary tight material 116 attached to the water stop piece 117 is attached to the lower end portion of the vertical frame 113 at the abutting portion, that is, the lower corner portion between the vertical frame 113 and the lower frame 111, and this is attached to the floor. It is made to contact | abut to the side surface of the vertical frame side edge part of the floor tight material 112 attached to the surface, and the leakage of the water from the said corner part is prevented.

  In this conventional waterstop material structure, the abutting portion between the lower frame waterstop material and the vertical frame waterstop material can be satisfactorily used as a waterstop material. However, in the squeezed part between the vertical frame side end of the lower frame water blocking material mounting groove and the lower frame side lower end of the vertical frame water blocking material mounting piece, drainage flows around by a capillary phenomenon through a slight gap, and Water may leak from this part by applying water pressure (or air pressure).

Therefore, as shown in FIG. 11, the water is reliably stopped at the squeezed portion between the vertical frame side end portion of the groove in which the lower frame water stop material is mounted and the lower frame side lower end portion of the vertical frame water stop material mounting piece. Therefore, between the outer end portion 203 of the lower frame side of the lower frame and the lower end portion 205 of the lower frame side of the vertical frame, the water-stopping material portion positioned in the lower frame groove when mounted and the upper surface of the lower frame 232 is exceeded. In other words, the groove is attached by interposing a water-stopping material piece 211 having an off-groove water-stopping material portion 215 protruding upward from the lower frame 232, and connecting the both. By pressing the outer water blocking material portion 215 against the lower end 205 on the lower frame side with a separately formed water blocking material presser 221, the gap is not generated in the squeezed portion, and the portion is surely water stopped. Is also known (see Patent Document 2).
JP 2002-147137 A Japanese Patent Laying-Open No. 2005-200975

  In the above conventional ones, the floor or lower frame water-stopping material (generally referred to simply as the lower frame water-stopping material) is attached to the fitting groove provided on the floor or lower frame (generally referred to simply as the lower frame). It has a structure that cannot be easily removed. However, since both ends of the lower frame water stop material, that is, the contact surfaces with the auxiliary water stop material or the vertical frame are merely abutting against the water stop material, when an external force is applied to the lower frame water stop material, It easily falls down due to its flexibility. If it falls in this way or if the end of the bottom frame water stop material is carelessly pulled during cleaning, for example, a gap will be created between the contact surface of the vertical frame and the end surface of the bottom frame water stop material (in extreme cases) May cause the leakage of water.

When the bottom frame water-stopping material falls, slips, or comes off, there is a gap between it and the opposite side, and water overflowing from the bathroom flows out of the gap, for example, to the changing room side Problems arise.
Therefore, the present invention has been made in view of the above-mentioned problems of the prior art, and the object thereof is a lower frame at a joint portion between a door opening vertical frame and a lower frame, such as a bathroom, which is particularly difficult to stop water. It is to prevent the water-stopping material from falling down, slipping off from the mounting groove, or detaching, and ensuring water-stopping when the door is closed.

The present invention is a water shut-off block, and the upper frame is arranged in the junction corners of the lower frame, and left and right vertical frame and the lower frame in the opening frame and framework square the right and left vertical frame, An end portion of the lower frame water-stopping material has a side surface that contacts an end surface of the lower frame water-stopping material provided on the lower frame, and includes a support portion that supports an inner surface of the end portion of the lower frame water-stopping material on the side surface. Is supported in an immobile state to prevent water leakage to the outdoor side together with the lower frame water stop material.
Another aspect of the present invention is a joiner, the upper frame, the junction corners of the lower frame, and left and right vertical frame and the lower frame in the opening frame and framework square the right and left vertical frame, the invention It is characterized by arranging a water stop block.

(Function)
The water blocking block according to the present invention is disposed at both ends of the water blocking material attached to the mounting groove of the lower frame. The water blocking block is attached to the lower frame or the vertical frame by suitable fixing means such as screws. Here, when the water blocking block is attached in contact with the side surface of the end portion of the lower frame water blocking material on the outdoor side of the opening, the water blocking block is pressed when the lower frame water blocking material is pushed to the outdoor side by an external force. The bottom frame water-stopping material is supported from the outdoor side so that is fixed. Further, when an external force in the reverse direction is applied, the lower frame water stop material is similarly supported in an immovable state by the support pins of the water stop block to prevent falling or the like. Furthermore, when the supporting arm of the water blocking block is inserted into the end of the lower frame water stopping material and arranged on the indoor side, even if any external force acting indoor or outdoor acts on the lower frame water stopping material, The end portion of the lower frame water-stopping material is supported in a fixed state by a support arm to prevent the falling of the water-stopping material.

According to the present invention, it is possible to prevent the bottom frame water-stopping material from collapsing due to an external force, or the mounting and shifting or coming off, so that water can leak at both ends of the bottom frame water-stopping material as in the past. Absent.
In addition, in the case where the vertical frame side end side surface of the lower frame water stop material is supported on the back surface of the water stop block, as a result of the water stop block and the lower frame water stop material being joined closely, the end of the lower frame water stop material Not only can the water stop on the side be performed more reliably, but it can also be easily applied to an existing bottom frame with a water stop material.
Also, in the case where the end of the lower frame water stop material is fixedly supported by the support arm of the water stop block, the lower frame water stop material and the water stop material are simply inserted into the lower frame water stop material. In addition to being able to be coupled to the water, the upper surface is formed on the water guide surface, so that water drops descending along the vertical frame can be smoothly guided to the indoor lower frame or floor surface. It is possible to reliably stop the water at the joint portion. Moreover, cleaning is also easy.
In the present onset bright, and supports the immobility, when the end of the lower frame water stopping material is subjected to an external force, other members such as vertical frame and water shut-off block in contact with the lower frame water stopping material end This means that the movement is limited so that there is no gap between which water leakage occurs, and it does not necessarily mean that the movement is not complete.

Hereinafter, with reference to the accompanying drawings, an example in which a water blocking block according to an embodiment of the present invention is applied to a bathroom door frame which is an example of an opening frame will be described.
FIG. 1 is a front view generally showing a door frame and a door in an opening portion between a bathroom configured by a unit bath and a dressing room.
The bathroom door frame is formed of an aluminum profile and the like, and the vertical frame 10, the upper frame 20 ', and the lower frame 20 are each formed into a rectangular frame. A well-known bathroom door 70 swings in the door frame. It is supported freely. Further, the bathroom door frame is attached between the bathroom having the same height, that is, no step, and the changing room floor so as to be barrier-free.
In the illustrated example, one bathroom door 70 that is hinged to one vertical frame side and opens and closes is shown. However, the bathroom door 70 is not limited to this and is composed of two or more folding doors. May be.

FIG. 2 is an exploded perspective view of the joint corner between the vertical frame 10 and the lower frame 20 of the opening frame.
As illustrated , the vertical frame 10 is integrally formed with a parting piece 11 extending to the outdoor side and a water-stopping material mounting frame 12 extending inward of the opening. A water-stopping material (not shown) is attached to the water-stopping material mounting frame 12 of the vertical frame, and when the bathroom door is closed, the water-stopping material comes into contact with the vertical shaft of the door and the door vertical wall and the vertical frame 10 is sealed.

The lower frame 20 is integrally formed with a lower frame water-stopping material mounting groove 21 at a substantially central portion in the width direction, and the lower frame water-stopping material mounting groove 21 extends along the mounting groove 21 at both upper ends thereof. Two protruding ridges 21a and 21b protrude into the groove, and in this embodiment, the indoor ridge 21a is provided above the outdoor ridge 21b. The lower frame water blocking material 40 is hollow and has a substantially rectangular cross section, and is made of an elastic material such as synthetic resin so that it can be deformed. The lower portion of the hollow portion corresponds to the protrusions 21a and 21b. Thus, grooves 40a and 40b are formed in the longitudinal direction. The lower frame water blocking material 40 is mounted so as to be slightly inclined toward the bathroom side by inserting the grooves 40a, 40b into the protrusions 21a, 21b of the mounting groove 21 .

The vertical frame 10 and the lower frame 20 are connected by, for example, screws (not shown) with a sealer 30 interposed as in the conventional case. The lower frame water-stopping material mounting groove 21 provided in the lower frame 20 ends before the joint end with the vertical frame of the lower frame, and the vertical frame 10 is formed on the flat surface 23 of the lower frame 20 where the mounting groove 21 does not exist. The notch end portion 12a of the water stop material mounting frame 12 is butted and integrated.
With this configuration, the lower frame water stopping material 40, the vertical frame water stopping material mounting portion of the open end of the water stopping material mounting frame 12 of the vertical frame 10 (pocket) water stopping material attached to 14 (not shown) When the bathroom door is closed, each water-stopping material comes into contact with the left and right vertical gutters and the upper and lower horizontal gutters of the door and seals the four circumferences thereof. In addition, the code | symbol 10a in a figure shows the opening inner side surface of the vertical frame 10. As shown in FIG.
In the present embodiment, a water stop block 50 described below, which is an auxiliary water stop material, is disposed at a joint corner between the vertical frame 10 and the lower frame 20.

FIG. 3 is a perspective view of the water blocking block according to the first embodiment, in which FIG. 3A shows the front side and FIG. 3B shows the back side.
The water blocking block 50 is made of, for example, synthetic resin, and has a top surface 51 and a bottom surface 55 that are parallel to each other and flat as shown in FIG. The rear surface 56 is a flat surface that rises perpendicularly from the bottom surface 55, and the trapezoidal side surface 53 whose upper surface side is shorter than the bottom surface side.
A concave portion 54a that is opened along the inclined surface is formed at a substantially central portion in the width direction of the surface 54, and a screw hole 54c for attachment is provided on the flat bottom surface 54b of the concave portion 54a. Further, the upper surface 51 is formed in a shape in which a portion on the side of the vertical frame 10 is partially cut away when the upper surface 51 is attached to the lower corner portion of the opening, that is, a substantially L shape in a top view. The narrow portion is a portion that contacts the back side surface of the water blocking material mounting frame 12 of the vertical frame 10 when the water blocking block 50 is disposed on the outdoor side of the opening, that is, on the side of the changing room. It is set according to the width of the water stop material mounting frame 12.

As shown in FIG. 3B, the water blocking block 50 has, for example, foam rubber on the back surface 56 side at a portion that contacts the side surface of the end portion of the lower frame water blocking material 40 when the water blocking block 50 is disposed on the changing room side. The waterproof material 57 made of is attached, and thereby the waterproof materials are brought into contact with each other at both ends of the lower frame waterproof material 40, and the lower frame waterproof material 40 is externally applied from the bathroom side as will be described later. In addition to preventing the mounting groove 21 from coming off, shifting, or falling down, the water stop function is further improved.
In addition, the height of the water stop block which concerns on this embodiment should just be higher than the height of the lower frame water stop material 40, for example, when an adult enters a bathtub vigorously with the bathtub full, the bathroom door Since the water level in the previous part may reach about 20 mm, it is preferably at least 20 mm in consideration of overflow of this bathtub.

  A pin member 58, which is substantially L-shaped in plan view, is attached to the back surface 56 of the water blocking block 50. As will be described later, the pin member 58 is inserted and locked in a retaining hole 44 (see FIG. 4A) provided on the side surface of the lower frame water stop material 40 so that an external force in the indoor direction is applied to the lower frame water stop material 40. In order to prevent movement of the lower frame water-stopping material 40 in a restrained or immovable state when acting, the lower frame water-stopping material is prevented from falling into the indoor side, or being displaced or detached from the mounting groove 21. belongs to. The substantially L-shaped pin member 58 makes it difficult for the lower frame water-stopping material to come off the mounting groove 21 when receiving an external force, and prevents the water-stopping material end surface and the vertical frame contact surface from separating when pulled. For this reason, it is preferable that the opening is installed outward so that the tip thereof faces the direction of the vertical frame 10.

FIG. 4A is a perspective view showing a state in which the lower frame water blocking material 40 is attached to the attachment groove 21 of the lower frame 20.
As shown in the drawing, the lower frame water stop material 40 is fitted into the mounting groove 21 and is inclined slightly to the indoor side, and abuts against the opening side end of the water stop material mounting frame 12 of the vertical frame 10. Has been placed. Further, as described above, a hooking hole 44 for inserting the substantially L-shaped pin member 58 of the water blocking block 50 is formed in the vicinity of the water blocking material mounting frame 12 of the lower frame water blocking material 40. It is installed.

FIG. 4B is a perspective view showing a state in which the water blocking block 50 is further attached in the state of FIG. 4A.
The water blocking block 50 is provided on the back surface 56 with one side surface thereof along the parting piece 11 of the vertical frame 10 and the back surface 56 along the back surface of the water blocking material mounting frame 12 and the opening side end surface thereof. The water stop material 57 is positioned in contact with the side surface of the lower frame water stop material 40, and the screw 54d is fitted into the screw hole 54c of the concave portion 54a at the position to be fixed to the lower frame 20.

FIG. 5 is a cross-sectional view of the main part showing a state when the water blocking block 50 is attached to the lower frame corner of the opening and the bathroom door 70 is closed.
When the door 70 is closed, the lower frame water blocking material 40 is pushed by the door lower rod 72. The pushed lower frame water blocking material 40 pushes and deforms the water blocking material 57 of the water blocking block 50 that comes into contact, and both water blocking materials completely adhere to prevent water leakage.
Since the water blocking block 50 is configured as described above, for example, with the bathroom door 70 closed, for example, a water flow strikes the lower frame water stop material at the corner of the opening lower frame, or a cleaning tool or the like is used during cleaning. When hitting, the conventional bottom frame water-stopping material falls down due to its external force, or in extreme cases, it comes off from the bottom frame groove and leaks water from it, but in this embodiment, the bottom frame water-stopping material is indoors. Even when a strong external force is applied, the end portion is supported by the surface of the water blocking material 57 of the water blocking block fixed to the outdoor side, so that it does not come off, shift or fall down.
Further, the water stop block 50 restrains the substantially L-shaped pin member 58 provided on the back surface from being hooked on the hook hole 44 of the lower frame water stop material 40 so as not to move indoors. Therefore, even if an external force is applied by, for example, a cleaning tool, it does not fall down or come off or shift.

FIG. 6 is a perspective view showing a state where the cover 80 is put on the water blocking block 50 of the first embodiment.
As shown in FIG. 3, the water blocking block of the first embodiment is provided with a concave portion 54a for attaching a screw to the inclined surface 54, and dust and water droplets are easily collected in this portion. Since it is not easy to remove accumulated dust and water droplets, a cover 80 is put on as shown in the figure to solve this problem.
The cover 80 has a smooth outer surface shape that is curved as illustrated, and covers the entire water blocking block 50. Thereby, for example, water drops falling along the back surface of the water blocking material mounting frame 12 of the vertical frame 10 easily flow down to the floor surface along this smooth upper surface. Further, even if dust adheres to the surface of the cover 80, it can be washed away or easily removed with a cleaning tool.
In addition, the cover 80 is not limited to what covers the whole water stop block 50 like illustration, For example, you may make it cover only an upper surface and the surface.
The cover 80 is formed of, for example, a synthetic resin, like the water blocking block, but the material is not particularly limited, and may be a metal having a smooth surface.

Next, a second embodiment of the water blocking block will be described.
