Description

Technical Field

[0001] The invention belongs to the technical field of public door curtains and relates to a rotating door curtain for a public toilet. Background Art

[0002] The national standard stipulates that the bathroom should have separate passages for men and women, and sight-blocking devices should be installed at the entrances for men and women. Currently, the most common way to block sight is to install doors and add door curtains. A more sophisticated way is to install a screen or wall inside and outside the door to block the outside view. A more complicated way is to design several turns inside and outside the door to completely block sight interference.

[0003] All of the above traditional methods have defects of varying sizes. The method of only setting a door will lose its sight shielding effect when the door is opened; the method of only setting a door curtain will also lose its sight shielding effect the moment the door curtain is lifted; setting screens or screen walls inside and outside the door cannot completely block the interference of indoor and outdoor sights, and also occupy the indoor and outdoor usable area, increasing the cost of the building and the inconvenience of the user; and the method of designing several turns at the door is basically the same as the defects of setting screens or screen walls inside and outside the door, but the degree is more serious. In fact, not only public toilets, but also public bathrooms, dressing rooms and other spaces have higher privacy requirements, and sight shielding is considered when designing or using them, but none of them can achieve a good shielding effect.

[0004] Therefore, a public toilet revolving door curtain is needed to solve these problems. Summary of the invention

[0005] The technical solution adopted by the present invention to solve the technical problem is: a public toilet rotating door curtain, comprising: a door curtain, a door frame, a hanger, and a wall. The door curtain is in the shape of a fan column, and the door curtain includes a radius portion and an arc portion. The radius portion is a vertical plane from the center of the circle to the circumference along the radius direction of the fan column, and the arc portion is a vertical arc surface along the circumferential side of the fan column. The vertical outer edge of the radius portion is spliced ​​and connected with a vertical side edge of the arc portion. The radius portion and the arc portion are both composed of a plurality of vertical long strips of door curtain strips spliced ​​and combined in the horizontal direction. The door frame is in a shape of opening on both sides, and the opening sides of the door frame are both arc-shaped, and the hanger is star-shaped; the arc-shaped outer part of the door frame is fixedly connected to the wall, and the upper part of the door curtain is hung on the hanger. The hanger, the door curtain, and the door frame share a vertical rotation axis, and the hanger rotates around the rotation axis. When the hanger drives the door curtain to rotate coaxially, the fan column The radius and arc portion of the door curtain rotate together, and when the user enters or exits, the user lifts the arc portion or enters or exits through the gap between the arc portion and the radius portion, and the radius portion can always play a shielding role when the user enters or exits; the door curtain is provided with two to four leaves, and the upper ends of the door curtains are evenly hung in the same horizontal circle. The sum of the curvature of the arc portion and the curvature of the door frame is not less than 360° of a circle. When the flow of people in the public place is large, the span of the door frame will also increase accordingly. Three or four door curtains can be added according to the specific situation. While increasing the pass rate, multiple door curtains will divide the entry and exit channels. Therefore, even if the flow of people is large, multiple people lifting the curtain at the same time will not affect the shielding effect; the door curtain is made of translucent material or opaque flexible material, and can provide a good shielding effect when the door curtain strips naturally droop.

[0006] Preferably, the height of the door curtain is half the height of the door curtain. The height of the half door curtain can provide a good shielding effect and is more convenient for sanitary maintenance. At the same time, the short line of sight under the door curtain can be used to know the oncoming flow of people and avoid them in advance.

[0007] Preferably, the bottom of the door curtain is at a height of 20 cm to 120 cm from the ground; a height lower than 20 cm may cause inconvenience to pedestrians or increase the workload of cleaning staff, while a height higher than 120 cm may reduce the shielding effect of the door curtain.

[0008] Preferably, the hanger includes a floor-standing hanger and a suspended hanger. The floor-standing hanger is easy to install, but it will cause a certain impact on ground accessibility, while the suspended hanger is more complicated to install but can provide a better ground accessibility rate. Even small-sized door frames can meet the entry and exit requirements of functional auxiliary vehicles such as wheelchairs.

[0009] Preferably, the width of the vertical door curtain strip of the radius portion is greater than twice the width of the vertical door curtain strip of the arc portion, and the width of the door curtain strip of the radius portion is greater than the width of the door curtain strip of the arc portion, so that the curtain lifting behavior of the arc portion is easier than the curtain lifting behavior of the radius portion, prompting the user to enter and exit from the arc portion and the gap between the arc portion and the radius portion as much as possible. When an emergency situation requires evacuation of personnel, the radius portion can still be used to lift the curtain for entry and exit, and will not cause any inconvenience to emergency passage.

[0010] Preferably, the hanger is provided with a motor to drive the rotation.

[0011] More preferably, the hanger is provided with an infrared sensing device, which is electrically connected to a motor so that when someone passes by, the motor rotates to drive the door curtain to rotate for the convenience of the user to enter and exit. When the time when no one enters and exits reaches a preset threshold, the motor stops rotating to save energy.

[0012] Preferably, when the door curtain is provided with four leaves, the width of the door frame is the same as the width of the wall; when the flow of people in the public place is large, the four door curtains rotate to facilitate the entry and exit of people, and the shielding effect of the door frame is relatively weakened. It is only necessary to set the door frame to the same width as the wall, which can also save the space occupied by the door frame. Therefore, even if only four door curtains are used, good visual shielding can be fully achieved.

[0013] The beneficial effects of the present invention are:

[0014] 1. The present invention enables the fan-shaped door curtain to reciprocate in the door frame, so that when users enter and exit public facilities that require visual shielding, the visual isolation inside and outside the public facilities will not be affected by the action of lifting the curtain when entering and exiting. Therefore, the present invention can completely block the visual interference of the space inside and outside the door curtain.

[0015] 2. The present invention uses flexible materials to make door curtain strips, and splices and combines the door curtain strips in the horizontal direction to form a door curtain. Therefore, when emergency evacuation is required, the pass rate of the doorway will not be affected.

[0016] 3. The present invention adopts a suspended hanger installation, which can provide a better ground traffic rate during normal use, and even a small-sized door frame can meet the requirements of functional auxiliary vehicles such as wheelchairs for entry and exit.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the relevant technologies in the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] refer to Figures 1 to 5 , a public toilet revolving door curtain, comprising: a door curtain 1, a door frame 2, a hanger 3, and a wall 4, the door curtain 1 is in a fan-shaped column shape, the door curtain 1 includes a radius portion 5 and an arc portion 6, the radius portion 5 is a vertical plane from the center of the circle to the circumference along the radius direction of the fan-shaped column, the arc portion 6 is a vertical arc surface along the circumferential side of the fan-shaped column, the vertical outer edge of the radius portion 5 is spliced ​​and connected with a vertical side edge of the arc portion 6, the radius portion 5 and the arc portion 6 are both composed of a plurality of vertical long strips of door curtain strips 7 spliced ​​and combined in the horizontal direction, the door frame 2 is in a shape of opening on both sides, the opening sides of the door frame 2 are both arc-shaped, and the hanger 3 is star-shaped; the arc-shaped outer part of the door frame 2 is fixedly connected to the wall 4, the upper part of the door curtain 1 is hung on the hanger 3, the hanger 3, the door curtain 1, and the door frame 2 share a vertical rotation axis, the hanger 3 rotates around the rotation axis, and when the hanger 3 drives the door curtain 1 to rotate coaxially, the fan-shaped door curtain 1 The radius portion 5 and the arc portion 6 rotate together. When the user enters or exits, he or she lifts the arc portion 6 or enters or exits from the gap between the arc portion 6 and the radius portion 5, and the radius portion 5 can always play the role of shielding when the user enters or exits; the door curtain 1 is provided with two to four leaves, and the upper ends of the door curtains 1 are evenly distributed and hung in the same horizontal circle. The sum of the curvature of the arc portion 6 and the curvature of the door frame 2 is not less than 360° of a circle. When the flow of people in the public place is large, the span of the door frame 2 will also increase accordingly. Three or four door curtains 1 can be added according to the specific situation. While increasing the passing rate, multiple door curtains 1 will divide the entry and exit channels. Therefore, even if the flow of people is large, multiple people lifting the curtains at the same time will not affect the shielding effect; the door curtain 1 is made of translucent material or opaque flexible material, which can provide a good shielding effect of sight when the door curtain strip 7 naturally droops.

[0025] Furthermore, the height of the door curtain 1 is half the height of the door curtain. The height of the half door curtain can provide a good shielding effect and is more convenient for sanitary maintenance. At the same time, the short line of sight distance under the door curtain 1 can be used to know the oncoming flow of people and avoid them in advance.

[0026] Furthermore, the bottom of the door curtain 1 is at a height of 20 cm to 120 cm from the ground; a height lower than 20 cm may cause inconvenience to pedestrians or increase the workload of cleaning staff, while a height higher than 120 cm may reduce the shielding effect of the door curtain.

[0027] Furthermore, the hanger 3 includes a floor-standing hanger and a suspended hanger. The floor-standing hanger is easy to install, but it will cause a certain impact on ground traffic, while the suspended hanger is more complicated to install but can provide a better ground traffic rate. Even a small-sized door frame 2 can meet the entry and exit requirements of functional auxiliary vehicles such as wheelchairs.

[0028] Furthermore, the width of the vertical door curtain strip 7 of the radius portion 5 is greater than twice the width of the vertical door curtain strip 7 of the arc portion 6, and the width of the door curtain strip 7 of the radius portion 5 is greater than the width of the door curtain strip 7 of the arc portion 6, so that the curtain lifting behavior of the arc portion 6 is easier than the curtain lifting behavior of the radius portion 5, prompting the user to enter and exit from the arc portion 6 and the gap between the arc portion 6 and the radius portion 5 as much as possible. When an emergency situation requires evacuation of personnel, the radius portion 5 can still be used to lift the curtain for entry and exit, and will not cause any inconvenience to emergency passage.

[0029] Furthermore, the hanger 3 is provided with a motor 8 to drive the rotation.

[0030] Furthermore, an infrared sensing device 9 is provided on the hanger 3, and the infrared sensing device 9 is electrically connected to the motor 8, so that when someone passes by, the motor 8 rotates to drive the door curtain 1 to rotate to facilitate the user to enter and exit. When the time when no one enters and exits reaches a preset threshold, the motor 8 stops rotating to save energy.

[0031] Furthermore, when the door curtain 1 is provided with four leaves, the width of the door frame 2 is the same as the width of the wall 4; when the flow of people in the public place is large, the four door curtains 1 rotate to facilitate the entry and exit of people, and the shielding effect of the door frame 2 is relatively weakened. It is only necessary to set the door frame 2 to be the same width as the wall 4, which can also save the space occupied by the door frame 2. Therefore, even if only four door curtains 1 are used, good visual shielding can be fully achieved.

[0032] Example

[0033] Embodiment 1: In this embodiment, the door frame 2 has a small span and is used in public places with a small amount of traffic. Therefore, a door frame 2 with a larger curvature is adopted, and two door curtains 1 are axially symmetrically arranged. Since the door frame 2 is small, a hanging hanger 3 is used, and the hanger 3 is hung on the top of the room.

[0034] When the user enters or exits, he or she lifts the arc portion 6 or enters or exits from the gap between the arc portion 6 and the radius portion 5. The radius portion 5, the arc portion 6 and the curved part of the door frame 2 cooperate to always serve as a shield when the user enters or exits. Even a door frame 2 with a small span can meet the functional requirements of wheelchairs and other auxiliary vehicles for entry and exit.

[0035] Embodiment 2: In this embodiment, the revolving door curtain is applied to a public place with a medium-sized flow of people. Therefore, three door curtains 1 are evenly distributed within a circle, and a hanging hanger 3 or a floor-standing hanger 3 may be considered.

[0036] When the user enters or exits, he or she lifts the arc portion 6 or enters or exits from the gap between the arc portion 6 and the radius portion 5. The radius portion 5, the arc portion 6 and the arc portion of the door frame 2 cooperate to always provide a shield for the user when entering or exiting. The width of the door curtain strip 7 of the radius portion 5 is greater than the width of the door curtain strip 7 of the arc portion 6, making it easier to lift the curtain of the arc portion 6 than the curtain of the radius portion 5, prompting the user to enter or exit from the arc portion 6 and the gap between the arc portion 6 and the radius portion 5 as much as possible. When an emergency situation requires evacuation of personnel, the radius portion 5 can still be used to lift the curtain for entry or exit, without causing any inconvenience to emergency passage.

[0037] Embodiment 3: In this embodiment, the revolving door curtain is used in public places with a large flow of people. Therefore, four door curtains 1 are evenly distributed within the circumference. Since the span of the door frame 2 is increased and the four door curtains 1 can greatly reduce the auxiliary role of the door frame 2 in shielding the line of sight, a floor-standing hanger 3 and a door frame 2 of the same width as the wall 4 are used.

[0038] When the user enters or exits, he or she lifts the arc portion 6 or enters or exits from the gap between the arc portion 6 and the radius portion 5. The radius portion 5, the arc portion 6 and the arc portion of the door frame 2 cooperate to always play a shielding role when the user enters or exits. Since four door curtains 1 are used in cooperation and rotation, when the user enters or exits, there are generally two door curtains 1 on the back side to shield the line of sight. Even if there is a large flow of people and multiple people continuously lift the curtains to enter or exit, the effect of shielding the line of sight will not be affected.

[0039] In summary, the present invention provides a revolving door curtain for a public toilet, which reciprocates in a fan-shaped door curtain in a door frame, so that when a user enters and exits a public facility that requires visual shielding, the visual isolation inside and outside the public setting will not be affected by the action of lifting the curtain when entering and exiting. Therefore, the present invention can completely block the visual interference of the space inside and outside the door curtain, and therefore the present invention has broad application prospects.

[0040] It should be emphasized that the above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
