Description

Technical Field

[0001] The invention relates to the technical field of wardrobe doors, and in particular to a swing-type flat door structure and a door system having the same. Background Art

[0002] In home life, wardrobe doors are one of the most common and important pieces of furniture. Most of the existing wardrobe doors are swing doors or sliding doors inside and outside the cabinet. Swing doors are opened or closed by hinge hardware, which has defects such as too large opening angle and occupying a large space outside the cabinet; while sliding doors inside and outside the cabinet are opened or closed by slide rails, but they can generally only open half of the space, which is inconvenient. For this reason, some merchants have combined the functions of hinges and slide rails to design a swing-type swing door, which can open the door leaf horizontally while hiding the door leaf on the side for storage.

[0003] At present, most of the swing-type swing doors on the market require manual operation during the entire process of pushing or pulling the door leaf in or out, which is rather troublesome. At the same time, the force of pushing or pulling the door leaf in or out cannot be adjusted, which reduces the user experience of the product. Summary of the invention

[0004] In order to overcome the defects of the above-mentioned prior art, the present invention provides a swing-type swing door structure and a door system having the same. When the door panel is pushed in or pulled out to half of its stroke, the door panel can be automatically pushed to the bottom or fully opened under the action of the reversing force of the swing arm, which is more convenient and saves manpower.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] A swing type flat door structure, comprising:

[0007] Cabinet;

[0008] A guide rail assembly, comprising an upper rail assembly and a lower rail assembly, which are arranged on one side of the cabinet and are located at the top and bottom respectively;

[0009] A vertical rod assembly, comprising a vertical rod body, wherein the top and the bottom of the vertical rod body are respectively slidably disposed on the upper rail assembly and the lower rail assembly;

[0010] a door panel, one side of which is hinged to the vertical rod body;

[0011] A swing arm assembly is arranged on one side of the cabinet and between the upper rail assembly and the lower rail assembly; the swing arm assembly comprises a bottom plate, at least one swing arm and an elastic member, one end of the swing arm is rotatably connected to the bottom plate, and the other end is slidably arranged on the vertical rod assembly; the elastic member is arranged between the swing arm and the vertical rod assembly;

[0012] When the door panel is pushed in to half of its stroke or pulled out to half of its stroke, the door panel drives the swing arm to swing, thereby driving the elastic member to deform and store elastic potential energy; subsequently, when the door panel is pushed in or pulled out again, the elastic member releases its elastic potential energy and drives the door panel to move via the swing arm until the door panel is pushed in to the bottom or fully opened.

[0013] The swing type flat door structure of the present invention, by providing a swing arm assembly, not only makes the force for pushing in or pulling out the door panel adjustable, but also when the door panel is pushed in or pulled out to half of the stroke, the reversing force of the swing arm can drive the door panel to be automatically pushed to the bottom or fully opened, which is more convenient and saves manpower.

[0014] Furthermore, a first guide wheel base is provided at one end of the swing arm, and at least one first guide wheel is provided on the first guide wheel base; the vertical rod assembly also includes a movable guide rail and a movable hanging platform arranged on the vertical rod body; the first guide wheel is slidably arranged on the movable guide rail; one end of the elastic member is hung on the first guide wheel base, and the other end thereof is hung on the movable hanging platform.

[0015] Furthermore, it also includes buffers arranged in the upper rail assembly and / or the lower rail assembly and located at both ends, and the vertical rod assembly also includes a shifting block arranged on the vertical rod body and cooperating with the buffer to trigger the action of the buffer.

[0016] Therefore, by respectively arranging buffers at both ends of the upper rail assembly and / or the lower rail assembly, a buffer function is provided when the door panel is pushed in or pulled out, thereby improving the user experience of the product.

[0017] Furthermore, it also includes a steel wire rope and a plurality of second guide wheel bases disposed on one side of the cabinet and located between the upper rail assembly and the lower rail assembly, and at least one second guide wheel is disposed on the second guide wheel base; the vertical rod assembly also includes a tension adjustment assembly and a fixing assembly disposed on the vertical rod body;

[0018] The steel wire rope is wound around a plurality of the second guide wheels, and one end of the steel wire rope is connected to the tension adjustment component, and the other end of the steel wire rope is connected to the fixing component.

[0019] Therefore, by adjusting the tension adjustment assembly on the vertical rod assembly, the wire rope can be tensioned to ensure that the vertical rod assembly can still achieve the synchronous horizontal sliding function after the door panel is loaded, thereby avoiding the deformation and tilting of the accessories of the vertical rod assembly in the track, thereby causing the door panel to tilt and cause unsightly or door panel scratches and other problems.

[0023] The first locking screw passes through the first through hole and is threadedly connected to the other end of the adjusting slider.

[0024] Therefore, by turning the first locking screw, the adjusting slider can be driven to move and then the steel wire rope can be pulled to achieve tensioning of the steel wire rope.

[0025] Furthermore, the fixing assembly includes a second fixing base and a second locking screw, wherein:

[0026] The second fixed base is detachably connected to the vertical rod body, and is provided with a second through hole for the steel wire rope to pass through and a threaded groove connected to the second through hole; the second locking screw is threadedly connected in the threaded groove and contacts the steel wire rope.

[0027] Therefore, by turning the second locking screw, it can be made to come into contact with the steel wire rope and tighten the steel wire rope to achieve fixation of the steel wire rope.

[0028] Furthermore, the vertical rod assembly further comprises a plurality of movable hinges arranged on the vertical rod body and spaced apart along the length direction thereof, wherein:

[0031] Furthermore, the hinge body further comprises an adjustment block and an eccentric nail, wherein:

[0032] The eccentric nail includes a main shaft and an eccentric shaft arranged at the bottom of the main shaft, and the eccentric shaft passes through the adjustment block and the movable seat body in sequence and is fixed; when the main shaft is rotated, the eccentric shaft can drive the movable seat body to move forward and backward in the horizontal direction.

[0033] Therefore, by adjusting the eccentric nail, the door panel can be driven to move forward and backward, thereby adjusting the size of the gap between the door panel and the cabinet body, thereby ensuring the sealing of the cabinet body.

[0034] Furthermore, the hinge body also includes an inner hinge arm hinged on the fixed seat body and the adjusting block respectively, an outer hinge arm hinged on the fixed seat body and the adjusting block respectively, and a limit pin passed through the outer hinge arm and used to interfere with the inner hinge arm to limit the opening and closing angle of the adjusting block, and a threaded hole is provided on the outer hinge arm for the limit pin to pass through and is threadedly connected to the limit pin.

[0035] Therefore, by adjusting the position of the limiting pin, the relative position between the limiting pin and the inner hinge arm can be changed, thereby achieving adjustment of the maximum opening angle of the door panel.

[0036] Furthermore, the vertical rod assembly also includes a slide arranged on the vertical rod body and located at both ends thereof, and the slide is provided with at least one pulley;

[0037] The upper rail assembly includes an upper rail body and a first slide rail disposed on the upper rail body and slidably matched with the pulley; the lower rail assembly includes a lower rail body and a second slide rail disposed on the lower rail body and slidably matched with the pulley.

[0038] In addition, the present invention further provides a door system, which at least includes the above-mentioned swing-type flat door structure and the side panel assembly, wherein:

[0073] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0074] Embodiment 1

[0075] See also Figure 1-18 The present invention first provides a swing-type flat door structure, including a rectangular cabinet 1, which has a front opening. A guide rail assembly and a vertical rod assembly 4 are provided on one side of the cabinet 1, and the guide rail assembly includes an upper rail assembly 2 and a lower rail assembly 3, which are arranged on one side of the cabinet 1 and are located at the top and bottom respectively; the vertical rod assembly 4 includes a vertical rod body 401, and the top and bottom of the vertical rod body 401 are slidably arranged on the upper rail assembly 2 and the lower rail assembly 3 respectively. In addition, it also includes a door panel 5, one side of which is hingedly connected to the vertical rod body 401, so that the cabinet 1 can be rotated to open or close, and at the same time, the door panel 5 can slide along the upper rail assembly 2 and the lower rail assembly 3 through the vertical rod assembly 4, so as to push or pull the door panel 5 in or out for storage.

[0076] For details, see Figure 7-10 The vertical rod assembly 4 includes two slides 404 installed on the vertical rod body 401 and located at the top side and the bottom side respectively, and a plurality of pulleys 4041 are provided on the slides 404; the upper rail assembly 2 includes an upper rail body 201 fixed to the side of the cabinet 1 and a first slide rail 202 provided on the upper rail body 201 and slidably matched with the pulleys 4041; the lower rail assembly 3 includes a lower rail body 301 and a second slide rail 302 provided on the lower rail body 301 and slidably matched with the pulleys 4041. Therefore, through the sliding cooperation between the plurality of pulleys 4041 and the first slide rail 202 and the second slide rail 302, the vertical rod assembly 4 can be horizontally slid along the axis direction of the first slide rail 202 or the second slide rail 302, thereby realizing the pushing in or pulling out of the door panel 5.

[0077] In this embodiment, six pulleys 4041 are provided on the slide 404, and the six pulleys 4041 are evenly arranged in two rows and three columns. The three pulleys 4041 in the first row slide on the top of the first slide rail 202 and the second slide rail 302, and the three pulleys 4041 in the second row slide on the bottom of the first slide rail 202 and the second slide rail 302; the top and bottom of the first slide rail 202 and the second slide rail 302 are both provided with a sliding shaft with a semicircular cross-section that slides with the pulley 4041.

[0078] See also Fig.10 , and also includes buffers 203 disposed in the upper rail assembly 2 and located at both ends. Specifically, the upper rail body 201 is provided with a mounting slot for the buffer 203 to be inserted and fixed; the vertical rod assembly 4 also includes a shifting block 407 disposed on the vertical rod body 401 and cooperating with the buffer 203 to trigger the action of the buffer 203.

[0079] Therefore, when the door panel 5 is pushed in or pulled out to a certain position, the shift block 407 on the vertical rod body 401 can trigger the buffer action to cause damping and buffering, thereby achieving a buffering function when the door panel 5 is pushed in or pulled out, thereby improving the user experience of the product.

[0080] It should be noted that the buffer 203 in this embodiment can be purchased on the market, and its specific structure and working principle do not belong to the technical content to be protected by this application. Those skilled in the art can learn about it from the prior art and will not be described in detail here.

[0081] Of course, in other embodiments, the buffer 203 can be set on the lower rail body 301 of the lower rail assembly 3, or the buffer 203 can be set on the upper rail body 201 of the upper rail assembly 2 and the lower rail body 301 of the lower rail assembly 3 at the same time, both of which can achieve the buffering effect, so it is not limited here.

[0082] See also Figure 1-6 The swing type flat door structure also includes a swing arm assembly 6 arranged on one side of the cabinet body 1 and located between the upper rail assembly 2 and the lower rail assembly 3. The swing arm assembly 6 includes a bottom plate 601 installed on the cabinet body 1 and located in the middle position, two swing arms 602 and an elastic member 604. One end of the two swing arms 602 is rotatably connected to the bottom plate 601, and the other end thereof is slidably arranged on the vertical rod assembly 4; the elastic member 604 is arranged between the swing arm 602 and the vertical rod assembly 4. Specifically, a first guide wheel base 603 is provided on the end of the swing arm 602 away from the bottom plate 601, two first guide wheels 6031 are provided on the first guide wheel base 603, and a bending plate 6032 is provided on the first guide wheel base 603; the vertical rod assembly 4 includes a movable guide rail 402 and a movable hanging platform 403 installed on the vertical rod body 401, and a convex column 4031 is provided on the movable hanging platform 403; the first guide wheel 6031 is slidably set on the movable guide rail 402; the elastic member 604 is a spring and one end of it is hung on the bending plate 6032 of the first guide wheel base 603, and the other end is hung on the convex column 4031 of the movable hanging platform 403.

[0083] Thus, when the door panel 5 is pushed in halfway or pulled out halfway, the elastic member 604 is stretched and stores elastic potential energy; when the door panel 5 moves to halfway, the door panel 5 is pushed in again or pulled out again, and the elastic member 604 is reset, contracted, and releases elastic potential energy, and drives the door panel 5 to move through the swing arm 602 until the door panel 5 is pushed in to the bottom or pulled out completely. In addition, by adjusting the position of the movable hanging platform 403 on the vertical rod body 401, the pulling length of the elastic member 604 can be lengthened or shortened, thereby changing the elastic potential energy of the elastic member 604, and then changing the force of pushing in or pulling out the door panel 5.

[0084] The revolving swing door structure of the present invention can adjust the position of the movable hanging platform 403, so that not only the force for pushing in or pulling out the door panel 5 can be adjusted, but also when the door panel 5 is pushed in or pulled out to half of the stroke, the reversing force of the swing arm 602 can drive the door panel 5 to be automatically pushed to the bottom or automatically fully opened, which is more convenient and saves manpower.

[0085] See also Figure 6-7 as well as Figure 11-14 The vertical rod assembly 4 further includes a plurality of movable hinges 408 disposed on the vertical rod body 401 and spaced apart along the length direction thereof. Specifically, the movable hinge 408 includes a movable seat body 4081 and a hinge body, wherein the movable seat body 4081 is connected to the door panel 5; the hinge body includes a fixed seat body 4084 and a connecting seat body 4088, wherein the fixed seat body 4084 is slidably disposed on the vertical rod body 401 through the connecting seat body 4088 and is detachably connected to the vertical rod body 401.

[0086] Specifically, a slide groove is provided on the vertical rod body 401, and a slider inserted into and slidable along the slide groove is provided on the connecting seat body 4088; mutually connected mounting holes are provided on the fixed seat body 4084 and the connecting seat body 4088. Thus, when a screw is passed through the mounting hole and abutted against the vertical rod body 401, the fixed seat body 4084 can be fixed to the vertical rod body 401.

[0087] Therefore, by adjusting the position of the fixing seat body 4084 on the vertical rod body 401, the door panel 5 can be driven to move up and down, thereby achieving the adjustment of the height of the door panel 5.

[0088] Specifically, the hinge body also includes an adjustment block 4082 and an eccentric nail 4083. The eccentric nail 4083 includes a main shaft and an eccentric shaft arranged at the bottom of the main shaft and offset from the center of the main shaft. The eccentric shaft passes through the adjustment block 4082 and the movable seat body 4081 in sequence and is fixed. Specifically, a limit hole and a horizontal slide groove (not shown in the figure) connected to the limit hole are provided on the adjustment block 4082. A mounting hole (not shown in the figure) connected to the horizontal slide groove is provided on the movable seat body 4081. The main shaft of the eccentric nail 4083 is located in the limit hole. The eccentric shaft of the eccentric nail 4083 passes through the horizontal slide groove and is fixed on the mounting hole. The eccentric shaft is engaged with the horizontal slide groove. Therefore, when the main shaft of the eccentric nail 4083 is rotated, the eccentric shaft can drive the movable seat body 4081 to move forward and backward in the horizontal direction.

[0089] Therefore, when a screwdriver is inserted into the cross-shaped groove on the main shaft and rotated, the eccentric shaft can drive the movable seat body 4081 to move relative to the adjustment block 4082, and the movable seat body 4081 will move horizontally back and forth along the guide direction of the horizontal slide groove, thereby adjusting the size of the gap between the door panel 5 and the cabinet body 1, thereby ensuring the sealing of the cabinet body 1.

[0090] In addition, the hinge body also includes an inner hinge arm 4085 hinged to the fixed seat body 4084 and the adjusting block 4082, an outer hinge arm 4086 hinged to the fixed seat body 4084 and the adjusting block 4082, and a limit pin 4087 penetrating the outer hinge arm 4086 and used to interfere with the inner hinge arm 4085. The outer hinge arm 4086 is provided with a threaded hole 40863 through which the limit pin 4087 can pass and is threadedly connected with the limit pin 4087. Specifically, the limit pin 4087 is a hexagon socket set screw, which can be driven to move along the axis of the threaded hole 40863 by rotating the limit pin 4087 with a tool, so that the relative position between the limit pin 4087 and the inner hinge arm 4085 can be changed, thereby adjusting the maximum opening angle of the door panel 5.
