Description

Technical Field

[0001] This utility model specifically relates to a folding door for a kindergarten classroom, belonging to the field of architectural decoration technology. Background Technology

[0002] Currently, folding doors are a common solution widely used in scenarios requiring temporary space partitioning or merging. Their advantage lies in not occupying interior space when open, facilitating quick switching between two adjacent classrooms. For example, during group teaching activities, two separate spaces can be integrated into a spacious area by fully unfolding the folding door; while during designated teaching or break times, the door can be closed to reduce noise interference and maintain teaching order.

[0003] However, existing folding door structures still have several shortcomings, including limitations in track installation: traditional folding doors mostly rely on ground tracks for sliding guidance and stability control. However, in places like kindergartens, raised tracks are often unsuitable for children's safety, thus limiting the application range of folding doors.

[0004] Insufficient sound insulation performance: Although some folding doors have a certain sound insulation function, they still cannot meet the requirements of the "Code for Sound Insulation Design of Civil Buildings" GB 50118 for indoor noise control in kindergartens during actual use. In particular, the airborne sound insulation between activity rooms should reach ≥50dB, and the allowable noise level should be ≤50dB.

[0005] Poor structural stability and safety: Due to the lack of a reasonable upper and lower support structure design, existing folding doors are prone to shaking and jamming under frequent opening and closing operations, posing safety hazards and are especially unsuitable for frequent contact and use by children.

[0006] Therefore, in order to address the shortcomings of existing technologies, a folding door for kindergarten classrooms is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a folding door for kindergarten classrooms to solve the problems mentioned in the background art.

[0008] This utility model achieves the above-mentioned objectives through the following technical solution: a folding door for a kindergarten classroom, comprising an upper support structure, a lower support structure, and a folding door disposed within the upper and lower support structures, characterized in that:

[0009] The upper support structure includes a track, a hanging wheel, and two wheels. A cavity is formed in the track, the hanging wheel is installed inside the cavity, and the two wheels are symmetrically installed on the upper end of the hanging wheel.

[0010] The lower support structure includes an H-shaped side keel, a limit stop, and a silent damping strip. The H-shaped side keel is installed at the lower end of the folding door, the limit stop is installed at both ends of the H-shaped side keel, and the silent damping strip is installed at the lower end of the limit stop.

[0011] The upper end of the folding door is provided with the H-shaped side keel, and the hanging wheel passes through the H-shaped side keel and is connected to the track.

[0012] Furthermore, the upper support structure is disposed in the ceiling, and the track is flush with the ceiling.

[0013] Furthermore, the wheel edges of the dual wheels have a profile that is lower on the outer side and higher on the inner side, in order to prevent the dual wheels from getting stuck in the track.

[0014] Furthermore, the folding door is internally composed of a steel frame, and the lower end of the hanging wheel is connected to the steel frame.

[0015] Furthermore, it also includes fireproof and environmentally friendly sound insulation cotton, which is placed inside the steel frame.

[0016] Furthermore, it also includes a splicing and sealing structure, which is disposed at both ends of the folding door.

[0017] Furthermore, the splicing sealing structure includes a groove and a recess, and each groove and recess is provided with an adhesive strip, which connects the groove and the recess together.

[0018] Furthermore, a sealing strip is also provided on the groove.

[0019] The beneficial effects of this utility model are:

[0020] This invention installs a track on the ceiling, with symmetrical double wheels (lower on the outer side and higher on the inner side) inside the track. This ensures that the double wheels are embedded or fitted into the cavity and remain in the center of the cavity, preventing jamming or seizing between the track edge and the double wheels on the hanging wheel. This ensures smooth movement of the folding door. Furthermore, silent damping strips are installed at the top and bottom of the folding door to provide resistance and slow down the movement speed of the folding door, thereby achieving vertical balance. This allows for sliding guidance and stability control on the ground without relying on a ground track. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 As shown, Figures 1-4 The illustration schematically shows a folding door for a kindergarten classroom according to the present invention.

[0028] A folding door for a kindergarten classroom includes an upper support structure 1, a lower support structure 2, and a folding door 4 disposed within the upper and lower support structures, characterized in that:

[0029] The upper support structure 1 includes a track 1.1, a hanging wheel 1.3 and a double wheel 1.2. A cavity 1.12 is opened in the track 1.1, the hanging wheel 1.3 is installed inside the cavity 1.12, and a symmetrical double wheel 1.2 is installed on the upper end of the hanging wheel 1.3.

[0030] The lower support structure 2 includes an H-shaped side keel 1.6, a limit stop 1.5, and a silent damping strip 1.4. The H-shaped side keel 1.6 is installed at the lower end of the folding door 4, the limit stop 1.5 is installed at both ends of the H-shaped side keel 1.6, and the silent damping strip 1.4 is installed at the lower end of the limit stop 1.5.

[0031] The upper end of the folding door 4 is provided with an H-shaped side keel 1.6, and the hanging wheel 1.3 passes through the H-shaped side keel 1.6 and is connected to the track 1.1.

[0032] Among them, the folding door 4 is equipped with H-shaped side keel 1.6 at both the top and bottom, the limit stop 1.5 is connected to the H-shaped side keel 1.6, and the silent damping strip 1.4 is connected to the limit stop 1.5.

[0033] Among them, the H-shaped side keel 1.6 is easy to set with limit stops 1.5 on both sides. The upper end of the limit stop 1.5 is fixed with a silent damping strip 1.4, which provides resistance to slow down the movement speed of the folding door 4. At the same time, the silent damping strips 1.4 on both sides are in contact with the track trajectory of the double wheels 1.2, so that the folding door 4 can always be in a vertical balance state.

[0034] The double wheels 1.2 are embedded or fitted into the cavity 1.12 and remain in the center of the cavity 1.12 to prevent the edge of the track 1.1 from getting stuck or locked with the double wheels 1.2 on the hanging wheel 1.3, thus ensuring that the folding door 4 can move smoothly.

[0035] The floor surface material 2.1 is installed on the ground, and the silent damping strip 1.4 is in contact with the floor surface material 2.1. The silent damping strip 1.4 increases the friction with the floor surface material 2.1, so that the sliding guidance and stability control can be achieved on the ground without relying on the ground track 2. This solves the problem that existing folding doors are prone to shaking and jamming under frequent opening and closing operations due to the lack of reasonable upper and lower support structure design, which poses safety hazards and is especially unsuitable for children to frequently come into contact with and use.

[0036] Among them, the upper and lower ends of the folding door 4 are equipped with silent damping strips 1.4, which enhance the connection and sealing of the folding door and improve the ability of the folding door 4 to block the propagation of sound waves in the vertical direction.

[0037] Furthermore, the upper support structure 1 is set in the ceiling 1.11, and the track 1.1 is flush with the ceiling 1.11.

[0038] Furthermore, the wheel edge 1.21 of the double wheel 1.2 has a profile that is lower on the outside and higher on the inside, in order to prevent the double wheel 1.2 from getting stuck in the track 1.1.

[0039] Furthermore, the interior of the folding door 4 is composed of a steel frame 1.7, and the lower end of the hanging wheel 1.3 is connected to the steel frame 1.7.

[0040] Furthermore, it also includes fireproof and environmentally friendly sound insulation cotton 4.1, which is placed inside the steel frame 1.7.

[0041] The 1.7-inch cavity of the steel frame is filled with 4.1-inch fireproof and environmentally friendly sound insulation cotton for sound insulation and fireproofing.

[0042] Furthermore, it also includes a splicing and sealing structure 3, which is set at both ends of the folding door 4.

[0043] Furthermore, the splicing sealing structure 3 includes a protrusion 3.1 and a groove 3.3, and both the protrusion 3.1 and the groove 3.3 are provided with adhesive strips 3.2, which connect the protrusion 3.1 and the groove 3.3 together.

[0044] Furthermore, a sealing strip 3.4 is also provided on the groove 3.3.

[0045] When the folding door 4 is unfolded, the protrusion 3.1 and the groove 3.3 form a physical interlock. The protrusion 3.1 squeezes the sealing strip 3.5 in the groove 3.3, generating continuous pressure, filling the gap, and playing a role in buffering and blocking the sound wave propagation medium, thus meeting the requirements for indoor noise control in kindergartens. In particular, the airborne sound insulation between activity rooms needs to reach ≥50dB, and the permissible noise level should be ≤50dB.

[0046] The folding door 4 is guided and stabilized by sliding on the track 2 to unfold and fold. When unfolded, two adjacent folding doors 4 are spliced ​​together and the protrusion 3.1 and groove 3.3 are physically engaged to form a partition wall for the kindergarten activity room. When folded, the folding door 4 can be easily stored at both ends of the classroom partition wall through the track 1.1.

[0047] The folding door 4 uses the track 2 for sliding guidance and stability control, thus completing the unfolding and folding actions. In the unfolded state, two adjacent folding doors 4 are spliced ​​together, and the protrusions 3.1 and grooves 3.3 on their edges achieve physical interlocking, forming a stable partition wall structure suitable for dividing the space of kindergarten activity classrooms. In the folded state, the folding door 4 slides along the track 1.1 and can be easily stored on both sides of the classroom, integrating two independent spaces into a spacious area, saving space and improving the flexibility of use.

[0048] The beneficial effects of this utility model are:

[0049] This invention installs a track on the ceiling, with symmetrical double wheels (lower on the outer side and higher on the inner side) inside the track. This ensures that the double wheels are embedded or fitted into the cavity and remain in the center of the cavity, preventing jamming or seizing between the track edge and the double wheels on the hanging wheel. This ensures smooth movement of the folding door. Furthermore, silent damping strips are installed at the top and bottom of the folding door to provide resistance and slow down the movement speed of the folding door, thereby achieving vertical balance. This allows for sliding guidance and stability control on the ground without relying on a ground track.

[0050] Installation steps of this utility model:

[0051] Step 1: According to the design requirements, mark the construction control line for position 4 of the folding door on the ceiling 1.11. During the construction of the ceiling 1.11 foundation, pre-install the track 1.1 and ensure the structure is firm and stable.

[0052] Step 2: The folding door 4 is pre-assembled in the factory. A steel frame 1.7 is erected and the hanging wheels 1.3 are fixed. Decorative panels are sealed on both sides of the steel frame 1.7. Fireproof and environmentally friendly sound insulation cotton 4.1 is installed in the gap between the decorative panels. H-shaped side keel 1.6 is provided at the upper and lower ends of the folding door 4. The limit stop 1.5 is connected to the H-shaped side keel 1.6, and the silent damping strip 1.4 is connected to the limit stop 1.5.

[0053] Step 3: The left and right edges of the folding door 4 are respectively provided with a protrusion 3.1 and a groove 3.3. Both the protrusion 3.1 and the groove 3.3 are provided with a rubber strip 3.2, and the groove 3.3 is provided with a sealing rubber strip 3.5. The hanging wheel 1.3 at the top of the folding door 4 is connected to the track 1.1 pre-installed on the ceiling 1.11 to ensure that the double wheels 1.2 on the track 1.1 move smoothly in the hollow cavity 1.12 of the track 1.1. When it is necessary to quickly switch between two adjacent classrooms, the folding door 4 slides on the track 1.1 for guidance and stability control, so as to realize the unfolding and folding of the folding door 4.
