Description

[Technical field]

[0001] The present invention relates to a banner hanging device, and more particularly to a banner safety lifting and hanging device that can be freely adjusted in position as needed to accommodate banners of different sizes. [Background technology]

[0002] Advertising banners, also known as banners, are a common outdoor advertising medium, mainly used for advertising, promotion, event announcements and other purposes. Advertising banners are generally made of durable materials such as polyester and PVC, which are resistant to wind and UV rays, ensuring durability and long-term use in various weather conditions. With the increase in advertising demand and technological advances, the design and production process of advertising banners has also become increasingly sophisticated, allowing them to display high-quality images and text, attracting the attention of the public.

[0003] Conventional advertising banners are well known as strip-shaped banners that are hung from ceilings or eaves. Although such strip-shaped banners are eye-catching, there are problems with hanging installation. First, in order to hang banners, it is necessary to find a structure to fix a protrusion or pole to the ceiling or eaves, which is limited in terms of space. Second, even if there is a fixing structure to fix the banner, it is fixed to the ceiling or eaves and difficult to move, so it can only be applied to banners of a specific size, and it is difficult to hang banners of different sizes, so there is a limit to the applicability of the size of the banner. Third, currently, hanging banners is mainly done by climbing to a high place by hand, which poses a certain risk. Fourth, the fixing structure to attach the banner, such as a vertical bar extending downward, cannot be removed or stored from its fixed position, so when the banner is not hung, the structure obstructs the line of sight or the passage of pedestrians, causing inconvenience.

[0004] Since conventional banners are prone to the above-mentioned problems when hanging, providing a banner hanging device that can effectively solve the above-mentioned hanging problems is one of the problems that must be urgently solved by businesses and developers in the related field.

The two ends 352 are located at opposite ends of the winding portion 351 and are fixed to opposite sides of the movable portion 13, respectively. When the worm 32 rotates, it drives and rotates the worm gear 33, which in turn rotates the two reels 34 accordingly, moving the cable 5 and moving the movable part 13 along the rail 11, thereby adjusting the relative position between the hanging means 20 and the position adjustment module 30.

[0034] When the worm 32 of the position adjustment means 30 is rotated, the worm gear 33 and the two reels 34 take up the cable 35, which slides along the rail 11 in conjunction with the movable part 13, and can adjust the relative position with respect to the mounting base 10 in conjunction with the hanging means 20. With the above structure, different standards of banners can be quickly adjusted and fixed, and the operation is convenient; the banner can be pulled tightly and neatly hung on the entrance ceiling of a building or the wall of a building, and the operation is convenient.

[0035] As shown in FIG. 4, the banner safety lifting and hanging device of this embodiment can be combined with a detachable and independent auxiliary means 40. The auxiliary means 40 includes a fixed rod 41, a gripping lever 42, a telescopic rod 43, a locking member 44, and an engagement member 45. The fixed rod 41 is a square rod, with a gripping lever 4 at one end and a telescopic rod 43 at the other end. At least a part of the gripping lever 42 is perpendicular to the fixed rod 41 and is used to rotate and hold the auxiliary means 40. The telescopic rod 43 is connected to the fixed rod 41 to form a telescopic structure, of which the telescopic rod 43 is also a square rod, and the telescopic rod 43 can be telescopic with respect to the fixed rod 41 but cannot rotate relative to it. A locking member 44 is provided between the fixed rod 41 and the telescopic rod 43, and the length of the auxiliary means 40 can be adjusted to match the height of the mounting base 10 by operating the fixed rod 41 and the telescopic rod 43 to switch between a locked state and an unlocked state. The engaging member 45 is provided at one end of the telescopic rod 43 facing the fixed rod 41, and has an engaging pin 451 on the side and a recessed groove 452 at the end. The shape of the recessed groove 452 corresponds to the shape of the rotating head portion 321.

[0036] In addition, the auxiliary means 40 has two functions. As shown in FIG. 1, FIG. 5 and FIG. 6, the user can first pass one end of the banner 1 through these collars 23 and fix it to the second bar 22. Then, the user inserts the engagement pin 451 of the engagement tool 45 of the auxiliary means 40 into the engagement groove 223 of the second bar 22 to engage it, and fixes the auxiliary means 40 to the second bar 22. Next, the user lifts the auxiliary means 40 to connect the second bar 22 together with the banner 1 to the first bar, and fixes the other end of the banner 1 to a distant fixed frame (not shown). The fixed frame is positioned at the same extension position of the mounting base 10 and faces the hanging means 20, which is convenient for hanging banners of various specifications at selected positions on the building. The fixed frame may be another set of banner installation and hanging devices.

[0037] 2, as shown in Figures 7 and 8, the user fits the groove 452 of the auxiliary means 40 into the rotating head 321 of the worm 32 of the position adjustment means 30, and fixes the auxiliary means 40 and the worm 32. After that, the user grips and rotates the grip lever 42 to rotate the worm 32, the worm gear 33, the two reels 34 and the cable 35, which move in conjunction with the movable part 13, and move the hanging means 20 along the rail 11 of the mounting base 10, thereby deploying or storing the curtain 1 of the present invention.

[0038] As shown in Fig. 9 to Fig. 11, the second preferred embodiment of the present invention discloses a banner safety lifting and hanging device mainly including a mounting base 50, a hanging means 60, and a position adjustment means 70. The main structures of the mounting base 50, the hanging means 60, and the position adjustment means 70 are the same as those of the first preferred embodiment, and the same technical contents will be omitted here. This embodiment is different from the first preferred embodiment in that the mounting base 50 has a rail 51 and a movable part 52 mounted on the rail 51 and connected to the position adjustment means to provide movement between the hanging means 60 and its connection part. The position of the movable part 52 mounted on the rail 51 is not fixed, and the position on the rail 51 can be adjusted by being driven by the position adjustment means 70. In this embodiment, the movable part 52 is a roughly gate-shaped member, and has two pivot arms 521, a pivot shaft 522, and a limiting member 523. The two pivot arms 521 are provided opposite each other and extend along a direction away from the mounting base 50. The pivot shaft 522 is provided between the two pivot arms 521 and passes through the two pivot arms 521. The limiting member 523 is provided between the two pivot arms 521 and is used to limit the rotation direction of the hanging means 60. The limiting member 523 may be a bar or a protrusion provided on the movable part 52. The mounting base 50 further provides a clip member 53 between the position adjustment means 70 and the movable part 52. The clip member 53 has two clamping arms 531 and an opening 532 defined and formed by the ends of the two clamping arms 531, and the two clamping arms 531 are provided symmetrically, and the two clamping arms 531 extend in a direction away from the mounting base 50. The two clamping arms 531 have a certain elasticity. In this embodiment, the clip member 53 and the movable part 52 are assembled or integrated, so that the clip member 53 can move together with the movable part 52 and is always a predetermined distance away from the movable part 52. In other embodiments, the clip member and the movable part are two independent parts, so that when the movable part is moved along the rail, the distance between the clip member and the movable part changes accordingly.

[0039] The hanging means 60 includes a rod 61 and a pivot member 62. The pivot member 62 is connected to one end of the rod 61 and pivotally attached to the movable part 52, and rotates the rod 61 relative to the movable part 52. The rod 61 can be implemented as a single rod material, or as a multi-joint rod material continuously combined as shown in the first preferred embodiment. The hanging means 60 can rotate between a first position and a second position. When the hanging means 60 is located at the first position, as shown in FIG. 9, it is approximately perpendicular to the mounting base 50 and is separated from the clip member 53 and is in a hanging-ready state. When the hanging means 60 is located at the second position, as shown in FIG. 11, it is approximately parallel to the mounting base and is stored between the two clamping arms 531 of the clip member 53 and is in a stored state.

[0040] As shown in Fig. 12, the banner safety lifting and hanging device of this embodiment can be used in combination with an independent auxiliary means 80 in addition to manually adjusting the position of the hanging means 60. The auxiliary means 80 includes an auxiliary body 81 and a locking device 82. The locking device 82 is provided at one end of the auxiliary body 81 and has a hook 821 and a recess 822. The hook 821 is located at the side edge of the locking device 82. The recess 822 is located at the tip of the locking device 82. Furthermore, the hook 821 and the recess 822 are grooves, and the hook 821 and the recess 822 have different shapes and opening directions depending on the position. The shape of the recess 822 is approximately the same as that of the hanging means 60, which is convenient for hooking.

[0041] Therefore, when the hanging means 60 is in the second position, the user uses the hook portion 821 of the auxiliary means 80 to hook one end of the hanging means 60 and apply a downward force to detach the hanging means 60 in the first position from the clip member 53, rotate it to the first position, and hang the banner. On the other hand, when the hanging means 60 is in the first position, the user uses the recess 822 of the auxiliary means 80 to hook one end of the hanging means 60 and apply an upward force to rotate the hanging means 60 in the first position to the second position, and inserts it between the two clamping arms 531 along the opening 532 of the clip member 53 to form the stored state.

[0042] As described above, the banner safety lifting and hanging device provided by the present invention can be used for banners of various sizes, and the mechanism provided is simple and durable, low cost, and the operation of installation, removal or adjustment is convenient, safe and practical. Meanwhile, the present invention can be stored when there is no need to hang a banner, which prevents the hanging means from being accidentally hit and damaged, or causing injury to others.

[0043] The above are preferred embodiments and design drawings of the present invention. However, the preferred embodiments and design drawings are merely examples and are not intended to limit the technical scope of the present invention. Any implementation by equivalent technical means or for the scope of rights covered by the contents of the following "Scope of Utility Model Registration Claims" shall not deviate from the scope of the present invention and shall be within the applicant's scope of rights.
