Description

The present invention relates to the technical field of arc-shaped door devices for booths installed at the entrances and exits of partitioned (comparted) booths (rooms) such as toilet booths and shower booths.

Today, as door devices installed at the entrances and exits of partitioned booths such as toilet booths, doorways are opened and closed by sliding an arc-shaped door body (door body) left and right on an arc-shaped rail when viewed from above. A so-called arc-shaped door device is known.
In addition, such an arc-shaped door body may be provided with a handle, as in the case of a flat (flat) door body, and in this case, the handle is provided with a handle that is loaded when the door body is opened and closed. It must be firmly installed to withstand the load. For this reason, it is proposed that the handle be attached to the stile on the side of the door that frames the door body, but the handle attached to the stile should be attached to the door stop on the side of the door when the door body is closed. Because of the close proximity to the handle, there is a problem in that when you try to open the door by grasping the handle, the door stop on the side of the door gets in the way and is difficult to operate.
Therefore, it has been proposed to place the handle in a position that is biased toward the door end side relative to the stile portion on the door end side so that the door stop on the door end side does not get in the way when opening the door (for example, see Patent Document 1). ).

Japanese Patent Application Publication No. 2019-148136

As mentioned above, when the handle is provided in a position that is biased toward the door end side than the door end side stile area, this area is provided with a filler (core material) such as honeycomb core material. It is virtually difficult to securely attach the handle. Therefore, in the door body, a reinforcing material is provided protruding from the vertical stile on the door end side toward the door end side, and a handle is attached to the reinforcing material. However, the conventional reinforcing material is As in the case, since it was a straight (flat plate) shape, the front and back face plates covering the area did not have an arc shape like the front and back plates of other parts, but became flat plates following the reinforcing material. However, there is a problem in that the appearance is impaired, and this is a problem to be solved by the present invention.

The present invention was created with the aim of solving these problems in view of the above-mentioned circumstances, and the invention of claim 1 provides a booth that slides in the left and right directions while drawing an arcuate trajectory. In an arc-shaped door device for a booth, which includes an arc-shaped door body for opening and closing an entrance/exit provided at the front, the door body is formed by a frame frame forming a frame around the door body, and the door. A reinforcing member is provided so as to protrude from the vertical stile on the door end side of the frame frame toward the door end side, and a handle is provided on the reinforcing member so as to protrude at least from the face plate on the inside of the booth.

According to the invention of claim 1, the reinforcing material provided for arranging the handle on the door end side part of the arc-shaped door body rather than the door end side vertical stile is formed by connecting a plurality of piece materials in an arc shape. Therefore, since the face plate of the reinforcing material part has an arc shape like the other parts, the appearance is not impaired.
According to the invention of claim 2, the arc-shaped reinforcing material can be formed using rectangular parallelepiped-shaped piece materials, and these piece materials can be reinforced by being bonded to the face plate. Therefore, there is no need to form each reinforcing material in advance as an integral piece having an arc shape, and the reinforcing material can be easily provided.
According to the invention of claim 3, the piece material can be made by cutting a columnar square material, improving work efficiency.
According to the invention of claim 4, it is possible to solve the problem that the corner portions on the arcuate outer circumference side of each piece material are chamfered, resulting in the face plate at the portion being angular, and the appearance is further improved.

It is a diagram.

Embodiments of the present invention will be described below based on the drawings. In the drawing, reference numeral 1 denotes a toilet booth, and a plurality of toilet booths 1 are installed adjacent to each other on the left and right, and there is a left and right gap on the front surface (front) to form an entrance/exit (opening) E. Front panel bodies 2 and 3 are provided on the door end side and door end side, and these front panel bodies 2 and 3 are provided at the tip (front end), and these front panel bodies 2 and 3 are connected to the back of the toilet booth. The fact that the partitions are formed by providing a side panel body 4 that partitions the space from the frame surface W such as an end wall is the same as in the conventional art, and further details thereof will be omitted.

Reference numeral 5 denotes a hanger-type door body (door body) having an arcuate shape in plan view, and the door body 5 projects upward from brackets 6a provided at the left and right upper end edges of the door body 5, and is attached to a hanger roller. (Hanging roller) 6 is provided, and the hanging rail (hanger rail, guide rail) 7 on which the hanger roller 6 is rolled and guided in the left and right direction has an arc shape so as to follow the arc shape of the door body 5, It is arranged so as to extend above the entrance E and the upper end of the side panel 4 on one side in the left and right direction (the door end side) when entering the toilet booth 1. Then, as the hanger roller 6 horizontally rolls on the hanging rail 7, the door body 5 slides in the left and right direction to close the entrance E and the door end side side panel body of the toilet booth 1. The toilet booth 1 enters into the toilet booth 1 on the 4th side and transforms into an open position in which the doorway E is opened. Note that T is a toilet bowl provided in the toilet booth 1.

The door body 5 is formed into a framework by upper and lower horizontal stiles 5a and 5b provided around the four circumferences, vertical stiles 5c and 5d on the left and right door end sides, and a horizontal stile 5e provided at an intermediate portion in the vertical direction. However, an auxiliary vertical stile 5f is further provided adjacent to the upper half of the door end side vertical stile 5c in parallel with a gap on the door end side, and these stile materials are surrounded by The space is filled with a filler (core material) 8 such as a honeycomb core material (paper core material), and the front and back surfaces are covered with a face plate 9. In this case, the face plate 9, each of the frames 5a to 5f, and the filler 8 are bonded together with an adhesive 10 to form an integral body.

The door body 5 is provided with a handle 11 for opening and closing, and a locking operation tool (operation knob) 12 adjacent to the upper side of the handle 11. The handle 11 is long in the vertical direction. It has a U-shape, and the leg portions 11a provided on both the upper and lower sides of the grip portion 11b protrude (extend) from the vertical stile 5c on the door end side toward the door end side while penetrating the face plate 9. It is attached and supported by reinforcing materials (liners) 13, which will be described later, provided above and below.
Note that the door body 5 of this embodiment is a self-opening type that moves the hanging rail 7 toward the fully open side under its own weight in a natural state (no opening/closing operation) with the door end side lowered. Therefore, there is no need to provide handles 11 on the outside surface of the booth where opening and closing operations are not required, but in this embodiment, handles 11 are provided on both the inside and outside. Conversely, if the door body 5 is of a self-closing type, it will be necessary to provide a handle 11 on the outside side for opening the door.
Incidentally, the lower end edge of the auxiliary vertical stile 5f is in contact with the upper end surface of the upper reinforcing member 13, so that the upper and lower sides are the upper horizontal stile 5a, the upper reinforcing member 13 is the upper side reinforcing member 13, and the left and right are the doors. A space S surrounded by the forward vertical stile 5c and the auxiliary vertical stile 5f is formed, and the space S includes the locking operating tool 12 and a connecting rod that is interlocked and connected to the operating tool 12. 14, and a latch 15 provided at the upper end of the connecting rod 14 protruding from the upper side stile 5a is removably engaged with a latch receiver 17 provided on the hanging rail 7 by operating the operating tool 12. By stopping the door body 5, the movement of the door body 5 in the fully closed position toward the door tail side is restricted, thereby making it possible to lock the door body 5.

The upper and lower reinforcing members 13 are formed using a plurality of rectangular parallelepiped piece materials 13a formed by cutting a columnar square material. In this case, each piece material 13a is With the end surfaces 13b of the piece materials 13a facing each other in contact with each other and arranged in a straight line, the inner peripheral surface of the arc is adhered (glued) with an adhesive tape 18, so that the pieces can be bent freely. They are connected in a series. In this case, the piece material 13a has an arcuate outer peripheral corner portion 13d chamfered in advance.
Then, the reinforcing material 13, in which the piece material 13a is bent and connected linearly, is connected to the door end side vertical stile 5c using the adhesive tape 18. , and the endmost piece material 13a adjacent to the vertical stile 5c are connected via U-shaped staples (tackers, needle-like connecting members) 13e on both the front and back sides.
In addition, in this case, regarding the upper reinforcing member 13, the space between the piece material 13a adjacent to the endmost piece material 13a connected to the door edge side vertical stile 5c and the lower end of the auxiliary vertical stile 5f is also They are connected via staples 13e, and in this embodiment, the reinforcing material 13 is reinforced by fixing the piece material 13a to the stile side of the door body 5. It has become.
Incidentally, to connect the vertical stile 5c on the door edge side and the piece material 13a at the end, the adhesive tape 18 for connecting the reinforcing material 13 is extended longer than the piece material 13a at the end. This can also be implemented by adhesively connecting the extended portion to the vertical stile 5c on the door end side.

As for the door body 5, the reinforcing material 13 is connected to the vertical stile 5c on the door edge side as described above, and the necessary members such as the filler 8 and the operating tool 12 are installed on the front and back sides of the door body 5 with adhesive ( For example, apply a face plate 9 coated with a hot melt type adhesive (a type that melts at high temperatures and solidifies at low temperatures) 10, heat it with a mold pressed from the front and back sides, and then cool it. However, such a processing method is already known (eg, Japanese Patent Publication No. 62-25512).
Adhesives for bonding such a face plate 9 include a type that adheres when the solvent evaporates and solidifies, a type that adheres when the mixed components of two liquids react and solidify, and a type that adheres by reacting with moisture. The face plate 9 can be bonded by selecting and employing a suitable adhesive as necessary from various types of adhesives, such as a type that adheres by solidifying the adhesive, and then through a bonding process corresponding to the type of adhesive. However, in this case, it goes without saying that in order to maintain the shape of the face plate 9 after adhesion, a mold is pressed against it in the adhesion process.

When the door body 5 is formed in this way, the reinforcing material 13 in which the piece materials 13a are linearly connected is The end surfaces 13b facing each other are bonded to the front and back face plates 9, with the corner portions 13c on the inner circumferential side of the arc in contact with each other (close to each other), and the facing distance becoming wider toward the outer circumferential side of the arc (separated by a wedge-shaped interval). However, in this case, the adhesive 10 enters the gap between the end surfaces 13b, and the piece materials 13a are not bonded (connected) with each other by the adhesive 10. As a result, the strength of the reinforcing material 13 can be increased.

In this embodiment configured as described above, the door body 5 for opening and closing the doorway E disposed at the front part of the toilet booth 1 is shaped like an arc, and the door body 5 has a longitudinal section on the door end side. A reinforcing member 13 is provided so as to protrude from the stile 5c toward the door end side, and when providing the handle 11 on the reinforcing member 13 in a state of protruding from the face plate 9, the reinforcing member 13 has a plurality of pieces 13a arranged in a circular arc. Since the door body 5 is connected in a series in the left and right direction to follow the shape, the door body 5 has an arc-shaped face plate 9 in the region where the reinforcing material 13 is provided as well as in other regions, so that the appearance is There is no loss of sexuality.

In this case, the piece material 13a has a rectangular parallelepiped shape, and the reinforcing material 13 has a continuous shape in which the corner portions 13c on the inner circumferential side of the arc of the mutually opposing end surfaces 13b of the adjacent piece materials 13a are in contact with each other. By being bonded to the face plate 9 in a connected state, it becomes integrated, and as a result, even if the reinforcing material 13 is formed using a plurality of piece materials 13a, the strength can be maintained. Therefore, there is no need to form the reinforcing material 13 as an integral piece having an arcuate shape in advance, and it can be provided simply and easily.
Moreover, since the piece material 13a is formed by simply cutting a columnar square material, processing is simple and workability is improved.

Moreover, in the reinforcing material 13 formed in this manner, the corner portion 13d on the outer circumferential side of the arc of the adjacent piece material 13a is chamfered, so that the face plate 9 at the corner portion 13d is in an angular state. This eliminates the problem of undesirable appearance, and further improves the appearance.

It should be noted that the present invention is of course not limited to the embodiment described above, and the same applies even if the arcuate outer corner portion 13d is not chamfered, as in the second embodiment shown in FIG. It can be carried out as follows.
Further, as in the third embodiment shown in FIG. 10(A), the piece material 13a is formed into a trapezoidal shape when viewed from the front in correspondence with the circular arc shape, and the upper base side with shorter side length is the inner peripheral surface of the circular arc. side, and the long lower bottom side is connected to the arcuate outer peripheral surface side. The piece material 13a in this case can be formed by cutting a linear square material so that the upper and lower bases are alternate, as shown in FIG.

INDUSTRIAL APPLICABILITY The present invention can be used as an arcuate door device for a booth installed at the entrance of a partitioned booth such as a toilet booth or a shower booth.
