Description

Concealed linkage structure for door and window handle assemblies and door and window components and assemblies using it This invention relates to door and window technology, and in particular to a door and window handle assembly with a concealed linkage structure for effortless opening of doors and windows, as well as door and window components and door and window assemblies using the door and window handle assembly. Known airtight doors and windows involve adding gaskets or other devices between the door or window panels and the frame, allowing the door or window panels to seal tightly with the frame, achieving airtightness or sound insulation. However, such doors and windows often cause inconvenience because the door or window panels are too tightly sealed to the frame, making them difficult to open. Various door and window handle assemblies designed to save effort and facilitate opening are known. Some use tension springs to provide rotational restoring force, some have complex internal structures, and some have large rotational linkages, resulting in many components being located outside the door and window frame. In other words, the known designs of effort-saving door and window handle assemblies have large, space-wasting parts, are structurally unstable and prone to loosening, are easily damaged by impacts, and still present operational inconveniences. Therefore, there is still room for improvement. In view of the above deficiencies, the purpose of this invention is to provide a door and window handle assembly with a concealed linkage structure, which can install the linkage structure inside the frame of the door and window components, making the structure more stable, easier to operate, smoother to operate, and reducing collision damage. To achieve the above objectives, the present invention provides a door and window handle assembly with a concealed linkage structure, comprising a frame assembly having a mounting hole and a swing chamber; a swing top member having a pivot seat pivotally connected to the swing chamber of the frame assembly, and an abutment wheel connected to the pivot seat; a mounting base being accommodated in the mounting hole of the frame assembly and fixed to the frame assembly; a connecting member being disposed between the frame assembly and the mounting base, pivotally connected to the mounting base; a connecting shaft being inserted into the pivot seat and the connecting member to rotate synchronously; and a handle being connected to the connecting member, operable to pivotally drive the connecting member to rotate, causing the abutment wheel of the swing top member to protrude and abut against a door or window seat. By means of the above-mentioned technical features, the door and window handle assembly with the concealed linkage structure of the present invention is made more stable, easier to operate, smoother to operate, and can reduce collision damage, thus effectively achieving the purpose of the present invention. Preferably, the frame assembly has a frame strip and an inner box, the inner box being housed within the frame strip, the swing chamber being located within the inner box, and the inner box being pivotally connected to the swing top component. This allows the swing top component to be more easily assembled into the frame assembly. Preferably, the frame assembly has a frame strip and a fixing piece, the fixing piece being mounted on or abutting against the frame strip, and the mounting base being locked to the fixing piece. This allows the mounting base to be more securely assembled into the frame assembly. Preferably, the frame assembly has a frame strip with a first piece and a second piece, and the mounting hole is formed between the first piece and the second piece. This makes it easier to form the mounting hole and to mount the component. Preferably, the door / window handle assembly includes a torsion spring disposed between the mounting base and the adapter, the torsion spring causing the adapter to rotate relative to the mounting base. This allows the handle to easily return to its original rotation. Preferably, the door and window handle assembly includes an outer cover that covers the mounting base; the mounting base has a protrusion, and the outer cover has an inner circumference that covers the protrusion of the mounting base. This allows the outer cover to be more securely mounted on the mounting base. Preferably, the mounting base has a protrusion, and the outer cover has a sleeve hole through which the protrusion of the mounting base passes. In this way, the outer cover can be more securely mounted on the mounting base. Preferably, the door / window handle assembly includes a compression spring that abuts against the outer cover and the handle, the compression spring being sleeved on the protrusion of the mounting base. In this way, the compression spring can more effectively provide pressure against the outer cover to maintain pressure against the mounting base. The present invention also provides a door and window component comprising a door and window handle assembly with a concealed linkage structure as described above, the door and window component including the frame assembly. This facilitates the construction of the door and window component using the door and window handle assembly. The present invention also provides a door and window assembly, comprising a door and window seat, and a door and window component as described above, the door and window component being slidably disposed on the door and window seat. This facilitates the formation of the door and window assembly by the door and window seat and the door and window component. 1: Door and window handle assembly 2: Door and window components 3: Door and window seats 4: Door and window assembly 5: Frame Group 10: Frame strip 11: First piece 111: First through hole 112: First bolt hole 12: End piece 121: Packing hole 122: First screw hole 13: Second piece 131: Mounting hole 20: Inner box 21: Second bolt hole 22: Rotating Room 23: First pivot hole 30: Fixing plate 31: Second through hole 32: Second screw hole 40: Top-mounted component 40A: Pivot seat 40B: Arrival at the ship 41: First Pivot 42: First shaft hole 43: Extending arm 50: Mounting base 51: Seat 52: Third bolt hole 53: First gear shift 54: Tokigaki 55: Third through hole 56: Protrusion 60: Adapter 61: Second Pivot 62: Spring assembly 63: Second gear shift section 64: Second shaft hole 65: Handle section 66: Fourth bolt hole 70: Working in shifts 80: Outer cover 81: Sleeve hole 82: Inner perimeter 90: throttle 91: Third connecting shaft hole 92: Third screw hole S1: Torsion spring S2: Compression spring Figure 1 is a schematic diagram of a door and window handle assembly and door and window components and door and window assemblies using the same according to a preferred embodiment of the present invention.

Figure 8 is similar to Figure 7, showing the already operated swing state. Figure 9 is a cross-sectional view along the secant line 9-9 in Figure 8. Please refer to Figure 1. In a preferred embodiment of the present invention, the door and window handle assembly 1 of the concealed linkage structure is included in a door and window component 2. The door and window component 2 is slidably mounted on a door and window seat 3 to form a door and window assembly 4. Please refer to Figures 2 to 9. The door and window handle assembly 1 of the concealed linkage structure includes a frame assembly 5, a swing top component 40, a mounting base 50, a transition component 60, a torsion spring S1, a connecting shaft 70, an outer cover 80, a handle 90, and a compression spring S2. The frame assembly 5 has a frame strip 10, an inner box 20, and a fixing piece 30, and the swing top component 40 has a pivot seat 40A and a stop wheel 40B. The frame strip 10 has two first pieces 11, one end piece 12, and one second piece 13. The first pieces 11 and the second piece 13 are parallel. One of the first pieces 11 has a first through-shaft hole 111 and two first bolt holes 112. The first through-shaft hole 111 is located in the middle, and the first bolt holes 112 are located above and below the first through-shaft hole 111. The end piece 12 is connected to the two first pieces 11 and has a housing hole 121 and two first screw holes 122. The second piece 13 has a mounting hole 131, which is formed between the first piece 11 and the second piece 13. The mounting hole 131 correspondingly covers the first through-shaft hole 111 and the first bolt holes 112. By using the first pieces 11 and the second piece 13, the mounting hole 131 can be formed more easily and components can be installed more easily. The inner box 20 is installed on the frame strip 10. The inner box 20 has two second bolt holes 21, a swing chamber 22, and two first pivot holes 23. The second bolt holes 21 are for bolts to be locked into the first screw holes 122 of the frame strip 10. The swing chamber 22 is formed from the side inward. The first pivot holes 23 are coaxially located on both sides of the inner box 20 and communicate with the swing chamber 22. By installing the inner box 20 on the frame strip 10, the swing top component 40 can be more easily assembled into the frame assembly 5. The fixing piece 30 is abutted or fixed to the frame strip 10. In this example, it abuts against the first piece 11 of the frame strip 10. The fixing piece 30 has a second through-shaft hole 31 and two second screw holes 32. The second through-shaft hole 31 corresponds to the first through-shaft hole 111 of the frame strip 10, and the second screw holes 32 correspond to the first bolt hole 112 of the frame strip 10. By abutting or fixing the fixing piece 30 to the frame strip 10, the mounting base can be more securely assembled to the frame assembly 5. The top-mounted component 40 is pivotally mounted on the inner box 20. The top-mounted component 40 consists of a pivot seat 40A and a stop wheel 40B. The pivot seat 40A has a first pivot 41, a first connecting hole 42, and an extension arm 43. The first pivot 41 is pivotally connected to the two first pivot holes 23 of the inner box 20, the first connecting hole 42 passes through the first pivot 41, and the extension arm 43 is connected to the first pivot 41. The stop wheel 40B is pivotally connected to the extension arm 43 and is used to roll and push the door / window seat 3. In this embodiment, when the top-mounted component 40 is not rotating, the line connecting the center of the first pivot 41 and the center of the stop wheel 40B is approximately horizontally upward at a 45-degree angle, but this is not a limitation of the present invention. The mounting base 50 is mounted on the frame strip 10. The mounting base 50 has a base 51, two third bolt holes 52, two first rotating parts 53, a protrusion 54, a third through-shaft hole 55, and a protrusion 56. The base 51 rests against the first piece 11 of the frame strip 10. The third bolt holes 52 correspond to the first bolt holes 112 of the frame strip 10. The first rotating parts 53 are located on the bottom surface. The protrusion 54 is located between the two third bolt holes 52. The third through-shaft hole 55 passes through the protrusion 54. The protrusion 56 is formed in a rectangular shape along the edge on the surface. The mounting base 50 is fixed by bolts passing through its third bolt hole 52 and the first bolt hole 112 of the first piece 11 and screwed into the second bolt hole 32 of the fixing piece 30. The adapter 60 is mounted on the mounting base 50. The adapter 60 has a second pivot 61, a spring mount 62, a second stop 63, a second connecting shaft hole 64, a handle 65, and a fourth bolt hole 66. The second pivot 61 pivots in the third through-hole 55 of the mounting base 50. The spring mount 62 is connected to the second pivot 61. The second stop 63 is located on the spring mount 62. When the adapter 60 rotates, the second stop 63 can abut against the first stop 53 of the mounting base 50. The second connecting shaft hole 64 is formed from the rear end into the second pivot 61. The handle 65 is connected to the second pivot 61. The spring mount 62 has multiple spring abutments 621. The torsion spring S1 is sleeved on the second pivot 61 of the adapter 60 and housed in the spring mounting part 62. The two ends of the torsion spring S1 abut against the two first stop parts 53 of the mounting base 50 respectively, and the two ends of the torsion spring S1 also abut against the spring abutment edge 621 of the adapter 60 respectively. The torsion spring S1 provides the restoring force for the adapter 60 to swing relative to the mounting base 50. The two ends of the connecting shaft 70 are respectively inserted into the first shaft hole 42 of the swing top member 40 and the second shaft hole 64 of the adapter 60, so that the connecting shaft 70 can rotate the pivot seat 40A of the swing top member 40 by means of the adapter 60. An outer cover 80 is fitted onto a mounting base 50. The outer cover 80 has a sleeve hole 81 and an inner circumference 82. The sleeve hole 81 fits onto the protrusion 54 of the mounting base 50, and the inner circumference 82 is rectangular and fits onto the protrusion 56 of the mounting base 50. In this way, the outer cover 80 can be more securely fitted onto the mounting base 50. The throttle 90 is connected to the adapter 60. The throttle 90 has a third shaft hole 91 and a third screw hole 92. The handle portion 65 of the adapter 60 is inserted into the third shaft hole 91 of the throttle 90, so that the adapter 60 and the throttle 90 rotate synchronously. The throttle 90 and the adapter 60 are connected by a bolt passing through the fourth bolt hole 66 of the adapter 60 and locking it into the third screw hole 92 of the throttle 90. A compression spring S2 is fitted onto the protrusion 54 of the mounting base 50. One end of the compression spring S2 abuts against the outer cover 80, and the other end abuts against the throttle 90. A washer may also be provided between the compression spring S2 and the throttle 90. That is, the compression spring S2 abuts against the outer cover 80 and the throttle 90, and the compression spring S2 can more effectively provide pressure against the outer cover 80 to keep it pressed against the mounting base 50. The components of this embodiment are described above. The usage is explained below using the diagram as an example. When attempting to open the door or window, the handle 90 is turned to the right. The handle 90, in turn, drives the adapter 60, which rotates against the force of the torsion spring S1. This rotation of the adapter 60, in turn, drives the pivot 70, which in turn rotates the swing-top component 40. The abutment wheel 40B of the swing-top component 40 then protrudes further from the frame 10 and rolls against the door / window seat 3, thus effortlessly pushing the door / window component 2 relative to the door / window seat 3. Because the door / window component 2 is relatively tightly closed against the door / window seat 3, requiring considerable force to open, this invention provides a force-saving effect. By mounting the base 50, adapter 60, and torsion spring S1 inside the frame assembly 5, the structure is more stable, the operation is easier, the operation is smoother, and the collision damage is reduced. By using a torsion spring S1 to provide rotational force, the torsion spring S1 abuts against the mounting base 50 and the adapter 60 respectively, which can be easily rotated and positioned, saving space. The torsion spring S1 can be installed through the spring mounting part 62 of the adapter 60. The spring mounting part 62 can protect the torsion spring S1 from impact and make the torsion smoother. By providing a bolt locking device 50 with a second screw hole 32 on the fixing plate 30, the locking can be more stable and less prone to loosening. It can also avoid the need to tap the frame strip 10 of the frame assembly 5 of the door and window component 2, and can be easily applied to the frame assembly 5 of various door and window components 2. The first stop 53 of the mounting base 50 is symmetrically arranged on the left and right sides. One side of the first stop 53 can be used for left-opening and the other side of the first stop 53 can be used for right-opening, so that the parts can be shared. In addition, the adapter 60 can also be used for both left-opening and right-opening. In addition to the above embodiments, the present invention can also be implemented in the following variations: For example, the aforementioned frame strip 10 and inner box 20 can also be integrated. Alternatively, the aforementioned frame strip 10 and fixing piece 30 can also be integrated. Alternatively, the mounting base 50 can be locked to the fixing piece 30, the mounting base 50 can be locked to the frame strip 10, or the mounting base 50 can be locked to the inner box 20. The present invention provides a door and window component 2, which includes a door and window handle assembly 1 with a concealed linkage structure as described above, and the door and window component 2 includes the frame assembly 5. The present invention provides a door and window assembly 4, including a door and window seat 3, and a door and window component 2 as described above, which is slidably disposed on the door and window seat 3. In summary, the door and window handle assembly with the concealed linkage structure of the present invention, as well as the door and window components and assemblies using it, can install the linkage structure within the frame group 5 of the door and window component 2, resulting in a more stable structure, easier operation, smoother operation, and reduced collision damage, thus effectively achieving the purpose of the present invention. Finally, it must be stated again that the constituent elements disclosed in the above-described embodiments of the present invention are merely illustrative examples and are not intended to limit the scope of this application. Substitutions or variations of other equivalent elements should also be covered by the scope of the patent application in this application. 10: Frame strip 11: First piece 12: End piece 13: Second piece 20: Inner box 40: Top-mounted component 80: Outer cover 90: throttle
