Description

[0002] The conventional structure for installing non-drilling curtains involves connecting a non-drilling installation assembly to at least one end of an installed crossbar and then installing it so that it is supported inside the window frame. Although this installation structure does not damage the wall because it does not require drilling holes, light leaks out through the gaps because the curtain must be fitted inside the window frame, preventing both sides of the curtain from completely blocking light. Therefore, to solve the problem of light leakage, the internally mounted non-drilling installation structure was changed to an externally mounted structure. This means that while the non-drilling installation assembly is still installed to be supported inside the window frame, the installed crossbar is changed from an internal type to an external type installed on the surface of the window frame, allowing the width of the curtain to exceed the width of the window frame, thereby enabling complete light blocking. However, during actual use, the externally mounted structure is not as sturdy as the internal type, making the externally mounted non-drilling installation structure prone to detachment.

[0021] As illustrated in FIGS. 1 to 8, the external non-perforated curtain installation mechanism provided by the present invention comprises a crossbar (1) exposed to the outside of a window frame, a first installation assembly (2) and a second installation assembly (3) installed to be supported inside the window frame in alignment with the crossbar (1), wherein the first installation assembly (2) and the second installation assembly (3) are connected to the crossbar (1) facing each other, and the first installation assembly (2) and the second installation assembly (3) slide along the longitudinal direction of the crossbar (1) in an unlocked state to conveniently adjust the distance between the first installation assembly (2) and the second installation assembly (3) so as to be matched to window frames of various widths, wherein the width of the window frame refers to the distance between the inner frames of the window frame, and the first installation assembly (2) and the second installation assembly (3) are fixed to the crossbar (1) in a locked state, and when the installation distance is determined, the first installation assembly (2) and the second installation assembly (3) are supported on the inner frames of the window frame, and the first installation assembly (2) and the second installation The assembly (3) is fixed to the crossbar (1), so that the crossbar (1) can be installed on the outer surface of the window frame without the need to drill a hole, and an auxiliary member (4) that can be attached to the inner frame of the window frame is connected to both the first installation assembly (2) and the second installation assembly (3). By additionally installing the auxiliary member (4) on the first installation assembly (2) and the second installation assembly (3), the contact area between the first installation assembly (2) and the second installation assembly (3) and the inner frame of the window frame is increased, making the overall installation structure more robust and preventing the curtain from falling off easily during use.

[0022] Here, the auxiliary member (4) includes a main connecting surface (4.1) that can be attached to the inner frame of the window frame. Since the main connecting surface (4.1) is flat, it can be completely adhered to the inner frame of the window frame, thereby increasing the contact area and frictional force, and improving stability and robustness during installation.

The first tightening member (2.2) and the first connecting member (2.1) are fixedly connected. The first tightening member (2.2) may be integrally molded with the first connecting member (2.1) or may be a detachable fixed connection structure, thereby ensuring that the first tightening member (2.2) and the first connecting member (2.1) slide together. After installation, the connection does not become loose, which would otherwise hinder the installation of the crossbar (1). The first tightening member (2.2) is used to tighten the inner frame of the window frame. The first switching member (2.3) is installed on the first connecting member (2.1) so that the first connecting member (2.1) can be adjusted to move or be fixed to the crossbar (1). In this embodiment, preferably, the first switching member (2.3) fixes the first connecting member (2.1) in a screw-rotation tightening structure, and the first connecting member (2.1) and the slide rail (1.1) of the crossbar (1) are clamped through the screw-rotation tightening of the first switching member (2.3), thereby fixing and installing the first connecting member (2.1). Conversely, when the first switching member (2.3) is loosened, the lock of the first connecting member (2.1) can be released, so that the first connecting member (2.1) slides along the slide rail (1.1) to adjust its position, and the first switching member (2.3) may also have a different structure, such as a buckle or an inverted tooth, to perform the locking and unlocking functions, which are not described again here. The first tightening member (2.2) is connected to the auxiliary member (4), and the auxiliary member is the first auxiliary member, and the first auxiliary member and the first tightening member (2.2)2) By matching, the contact area with the inner frame of the window frame is increased, thereby making the installation structure more stable and robust; a first non-slip pad (2.4) is installed on the outer cross-section of the first tightening member (2.2), and the first non-slip pad (2.4) can increase frictional force, thereby further improving stability during installation; first position fixing holes (2.2.1) are symmetrically installed on both sides of the first non-slip pad (2.4) of the first tightening member (2.2); first position fixing columns (2.2.2) are installed above and below the first non-slip pad (2.4) of the first tightening member (2.2); a gap (4.3) is installed at the top of the main connecting surface (4.1) of the first auxiliary member to avoid the first non-slip pad (2.4), and the gap (4.3) can be rectangular or U-shaped to serve as an avoidance mechanism. There are, and on both sides of the gap (4.3) in the main connecting surface (4.1), a connecting column (4.4) that matches the first position fixing hole (2.2.1) is installed, and the connecting column (4.4) is located on one side facing the first tightening member (2.2) from the main connecting surface (4.1), and the first position fixing hole (2.2.1) is connected to the connecting column (4.4) to perform a position limiting function, and on the upper and lower sides of the gap (4.3) in the main connecting surface (4.1), a connecting hole (4.5) that matches the first position fixing column (2.2.2) is installed. Preferably, in this embodiment, a U-shaped gap (4.3) structure is adopted so that a connecting hole (4.5) is installed below the gap (4.3) to match and connect to a first position fixing column (2.2.2), and a screw is additionally installed to reinforce the assembly and secure the connection, so that the main connecting surface (4.1) of the assembled first auxiliary member and the surface of the first non-slip pad (2.4) are placed on the same plane, ensuring that the main connecting surface (4.1) and the first non-slip pad (2.4) are completely bonded to the inner frame of the window frame during installation, thereby making the installation structure more stable and robust.

[0024] Herein, referring to FIGS. 3 to 7, the second installation assembly (3) includes a second connecting member (3.1), a second tightening member (3.2), a second switching member (3.3), and an adjustment assembly (3.4). The second connecting member (3.1) is slidably connected to a crossbar (1), and a corresponding slide rail (1.1) is installed on the crossbar (1) to install and move the second connecting member (3.1). The second tightening member (3.2) is movably matched with the second connecting member (3.1) through the adjustment assembly (3.4). The second tightening member (3.2) can tighten the inner frame of the window frame. The adjustment assembly (3.4) can adjust the tightening and locking of the second tightening member (3.2) to the inner frame of the window frame. Thus, the first installation assembly (2) and the second installation assembly (3) can be firmly supported and installed inside the window frame after being fixed to the crossbar (1). The second A switching member (3.3) is installed on a second connecting member (3.1) so that the second connecting member (3.1) can be adjusted to move or be fixed to the crossbar (1), and since the structure of the second switching member (3.3) is the same as that of the first switching member (2.3), it is not explained again. The second tightening member (3.2) is connected to the auxiliary member (4), and the auxiliary member (4) is the second auxiliary member. The second auxiliary member and the second tightening member (3.2) are matched to increase the contact area with the inner frame of the window frame, thereby making the installation structure more stable and robust. Here, the second auxiliary member is symmetrically identical to the structure of the first auxiliary member, and a second non-slip pad (3.5) is installed on the outer surface of the second tightening member (3.2). The second non-slip pad (3.5) can increase frictional force, thereby further improving stability during installation. Second position fixing holes (3.2.1) are symmetrically installed on both sides of the second non-slip pad (3.5) of the second tightening member (3.2), and a second position fixing column (3.2) is installed above and below the second non-slip pad (3.5) of the second tightening member (3.2).2) is installed, and a gap (4.3) is installed at the top of the main connecting surface (4.1) in the second auxiliary member to avoid the second non-slip pad (3.5). The gap (4.3) may be square or U-shaped and may serve as an avoidance mechanism. On both sides of the gap (4.3) in the main connecting surface (4.1), a connecting column (4.4) that matches the second position fixing hole (3.2.1) is installed. The connecting column (4.4) is positioned on one side facing the second tightening member (3.2) from the main connecting surface (4.1). The second position fixing hole (3.2.1) is connected to the connecting column (4.4) to perform a position limiting function. On the upper and lower sides of the gap (4.3) in the main connecting surface (4.1), a connecting hole (4.5) that matches the second position fixing column (3.2.2) is installed. Preferably, in this embodiment, a U-shaped gap (4.3) structure is adopted so that a connecting hole (4.5) is installed below the gap (4.3) and connected to a second position-fixing column (3.2.2), and a screw is additionally installed to reinforce the assembly and secure the connection, so that the main connecting surface (4.1) of the assembled second auxiliary member and the surface of the second non-slip pad (3.5) are placed on the same plane, ensuring that the main connecting surface (4.1) and the second non-slip pad (3.5) are completely bonded to the inner frame of the window frame when installed, thereby making the installation structure more stable and robust.

[0025] Herein, referring to FIGS. 5 and 7, an installation chamber (3.1.1) is installed in the second connecting member (3.1), and an adjustment assembly (3.4) is mounted inside the installation chamber (3.1.1) to adjust the tightening of the second tightening member (3.2) to the window frame. The adjustment assembly (3.4) includes a driving member (3.4.1), an interlocking member (3.4.2), a locking block (3.4.3), a first elastic member (3.4.4), and a second elastic member (3.4.5). A central axis (3.2.3) is installed in the second tightening member (3.2), and the central axis (3.2.3) penetrates the installation chamber (3.1.1). The first elastic member (3.4.4), the interlocking member (3.4.2), and the second elastic member (3.4.5) are sequentially fitted and connected to the central axis (3.2.3). A first elastic member (3.4.4) is in close proximity to the second tightening member (3.2), and the driving member (3.4.1) and the interlocking member (3.4.2) are vertically intersected and interlocked, and at least one end of the driving member (3.4.1) is in communication with the outside of the installation chamber (3.1.1), making it easy for an external tool to rotate the driving member (3.4.1), and the locking block (3.4.3) and the interlocking member (3.4.2) are threaded and matched, and the locking block (3.4.3) can lock or unlock the second tightening member (3.2) by reciprocating along the interlocking member (3.4.2), and a screw (3.6) and a gasket (3.7) are connected to the end of the central axis (3.2.3), so that the gasket (3.7) and the outer surface of the installation chamber (3.1.1) come into contact in a random state, and a second The clamping member (3.2) is positionally restricted.

[0026] Here, referring to FIG. 5, the driving member (3.4.1) is a worm, and the worm is installed in the installation chamber (3.1.1) in a transverse direction and rotates opposite to the installation chamber (3.1.1). The interlocking member (3.4.2) includes a worm gear part (3.4.2.1) and a threaded rod part (3.4.2.2), and the worm and the worm gear part (3.4.2.1) are engaged vertically to drive. This means that the worm gear part (3.4.2.1) penetrating the central axis (3.2.3) is installed along the length direction of the installation chamber (3.1.1), and the worm is installed along the width direction of the installation chamber (3.1.1). By adopting a structure in which the worm gear and the worm interlock vertically, on one hand, the operation is stable and noise is low, and on the other hand, it is automatically locked so that it cannot drive in the opposite direction, making it safe. Reliability is high, and the worm gear section (3.4.2.1) and the threaded rod section (3.4.2.2) are engaged and transmitted through a cross-sectional gear ring, that is, the worm drives the worm gear section (3.4.2.1), and the worm gear section (3.4.2.1) is engaged through the gear ring to rotate the threaded rod section (3.4.2.2) coaxially, and the worm gear section (3.4.2.1) and the threaded rod section (3.4.2.2) are installed in a separate manner, so not only are the worm gear section (3.4.2.1) and the threaded rod section (3.4.2.2) engaged and transmitted, but it is also possible to prevent the transmission from being interrupted due to gear disengagement and damage to parts due to excessive tightening, and the locking block (3.4.3) is thread-connected to the threaded rod section (3.4.2.2), and the locking block (3.4.3) is thread The second tightening member (3.2) can be tightened or released by moving back and forth along the threads of the threaded rod (3.4.2.2) by rotating the rod portion (3.4.2.2), and a through hole (3.1.2) that exposes the end of the worm is installed in the installation chamber (3.1.1), making it easy for an external tool to rotate the worm.

[0027] Here, referring to FIGS. 5 and 7, a position limiting member (3.1.3) is installed inside the installation chamber (3.1.1), and a ring-shaped stepped surface (3.4.2.2.1) that contacts the position limiting member (3.1.3) is installed on the threaded rod member (3.4.2.2), and one end of the first elastic member (3.4.4) contacts the other end of the threaded rod member (3.4.2.2) that is far from the ring-shaped stepped surface (3.4.2.2.1), and the other end of the first elastic member (3.4.4) contacts the second tightening member (3.2), and in a random state, the first elastic member (3.4.4) is in a compressed state, and one end of the first elastic member (3.4.4) pushes the threaded rod member (3.4.2.2), and the position limiting member (3.1.3) is axially When the threaded rod portion (3.4.2.2) is blocked and the other end of the first elastic member (3.4.4) pushes the second tightening member (3.2), a portion of the second tightening member (3.2) extends into the installation chamber (3.1.1), and the gasket (3.7) at the end of the central axis (3.2.3) is position-limited as it comes into contact with the outer cross-section of the installation chamber (3.1.1), thereby preventing the second tightening member (3.2) from protruding from the installation chamber (3.1.1).

[0028] Here, referring to FIG. 4, one end of the second elastic member (3.4.5) tightens the end far from the threaded rod (3.4.2.2) in the worm gear part (3.4.2.1), and the other end of the second elastic member (3.4.5) tightens the inner cross section of the installation chamber (3.1.1), so that in a random state, the second elastic member (3.4.5) is in a compressed state, so the worm gear part (3.4.2.1) can be pushed and engaged with the threaded rod (3.4.2.2). When an external part rotates the worm, the worm is linked to the worm gear section (3.4.2.1), and the worm gear section (3.4.2.1) can be linked to the threaded rod section (3.4.2.2) by the pushing action of the second elastic member (3.4.5). If the torsional force is greater than the elasticity, the worm gear section (3.4.2.1) compresses the second elastic member (3.4.5) in reverse, causing the gear to disengage, and immediately returns to its original position under the elastic action to mesh with the threaded rod section (3.4.2.2). Since the gear disengagement operation causes the threaded rod section (3.4.2.2) to already drive the locking block (3.4.3) to tighten the second tightening member (3.2), the second tightening member (3.2) can be firmly attached to the inner frame of the window frame, and by continuously rotating the worm to tighten, the worm gear section (3.4.2.1) There is no need to rotate it. Therefore, damage to parts that occurs during the rotating and tightening process, or accidents where the crossbar (1) comes off due to loose tightening, can be prevented.

[0029] Here, referring to FIG. 1, slide rails (1.1) that penetrate through both ends are installed on the crossbar (1), so that the first connecting member (2.1) and the second connecting member (3.1) of the first installation assembly (2) and the second installation assembly (3) are slidably connected, and a curtain can be hung on the crossbar (1).

[0030] When installing, referring to FIG. 8, first, the first switching member (2.3) and the second switching member (3.3) are loosened to attach the crossbar (1) to the outer frame of the window frame, and by adjusting the first connecting member (2.1) and the second connecting member (3.1), the first tightening member (2.2) and the second adjusting member (3.2) are respectively pressed against the inner frame of the window frame, and when the first auxiliary member and the second auxiliary member are joined to the window frame—that is, when the main connecting surface (4.1) and the inner frame of the window frame are joined and the edge cover (4.2) and the outer frame of the window frame are joined and fixed in place in advance—then the first switching member (2.3) and the second switching member (3.3) are tightened to firmly fix the first connecting member (2.1) and the second connecting member (3.1) to the crossbar (1), and when the preliminary installation is completed, when the worm is rotated with an external tool, the worm is coupled to the worm gear part (3.4.2.1), and the worm The gear section (3.4.2.1) interlocks with the threaded rod section (3.4.2.2), so that when the threaded rod section (3.4.2.2) rotates, the locking block (3.4.3) moves along the thread toward the second tightening member (3.2), and by tightening the second tightening member (3.2) from the locking block (3.4.3) to firmly lock it, the second tightening member (3.2) can be prevented from moving elastically. Thus, the first tightening member (2.2), the second tightening member (3.2), the first auxiliary member, and the second auxiliary member are installed to be supported inside the window frame, allowing the crossbar (1) to be firmly installed outside the window frame. At this time, if the worm is continuously rotated to tighten, the gear between the worm gear section (3.4.2.1) and the threaded rod section (3.4.2.2) disengages, that is, the threaded rod section (3.4.2.2) does not rotate, and the worm The gear section (3.4.2.1) compresses the second elastic member (3.4.5) in the opposite direction due to gear disengagement, thereby providing a protective function and preventing damage to the part due to excessive tightening. When disassembling, the worm can be tightened in the opposite direction, and the worm is coupled with the worm gear section (3.4.2.1). When the worm gear section (3.4.2.1) is coupled with the threaded rod section (3.4.2.2), the locking block (3.4.3) Since it is released by detaching from the second tightening member (3.2) in the opposite direction along the threaded rod portion (3.4.2.2), it can be conveniently disassembled, and there is no need to damage the window frame surface by punching or install it on a wall. In addition, the crossbar (1) is installed as an external structure, so if the length of the crossbar (1) is greater than the width of the window frame, the entire window frame can be completely covered, and when the curtain is drawn, light can be completely blocked, resulting in a superior light-blocking effect and preventing light from leaking out of the edges of the window frame. Furthermore, by additionally installing an auxiliary member (4) on the first installation assembly (2) and the second installation assembly (3), the contact area where the first installation assembly (2) and the second installation assembly (3) come into contact with the inner frame of the window frame can be increased, making the overall installation structure more robust and preventing the curtain from falling off easily during use.

[0031] The first elastic member (3.4.4) and the second elastic member (3.4.5) used in the present invention are both springs, and gaskets are installed at the point where the first elastic member (3.4.4) and the threaded rod part (3.4.2.2) come into contact with each other and at the point where the second elastic member (3.4.5) comes into contact with the worm gear part (3.4.2.1) to reduce friction and extend the service life, and the materials, reagents, and experimental equipment associated with the embodiments of the present invention are commercially available products that are compatible with curtain installation accessories unless otherwise described.
