Description

[Technical Field]

[0001] The present invention relates to a curtain hook, and more particularly to a curtain hook that has a position adjustment function while minimizing the tilt of the top of the curtain. [Background technology]

[0002] Demand for flat curtains has increased in recent years, and there is a demand for curtain hooks for flat curtains that improve the aesthetic appearance. Traditionally, standalone hooks (Figure 10) and hooks with adjuster functions have been widely used, but both have problems. The stand-alone hook has a one-piece structure where the hook and the main body are integrated, and the inclination of the upper part of the curtain is extremely small. However, due to the simple shape, it was difficult to add a position adjustment function (adjuster function). On the other hand, hooks with an adjustable function have a two-piece structure consisting of the hook and the main body, and although they have an adjustable function, they have the problem of creating a slope at the top of the curtain. Specifically, the attachment point when the curtain is hung from the insertion rod (hereinafter referred to as the curtain engagement point) and the attachment point when the hook is hung from the runner ring (hereinafter referred to as the ring engagement point) are not aligned linearly with respect to the vertical axis, so the hanging position of the curtain deviates from the ideal vertical line. This misalignment affects the hanging posture of the curtain, creating a slant at the top of the curtain, ultimately resulting in a problem of impaired visual aesthetics. Therefore, there is a demand for curtain hooks that have both an extremely small slope at the top of the curtain and a position adjustment function (adjuster function). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 8-266393 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional stand-alone hooks do not have a "position adjustment function (adjuster function)," and hooks with an adjuster function have the problem of creating an inclination at the top relative to the curtain body. Figure 10 shows a conventional stand-alone hook, and Patent Document 1 shows a conventional hook with an adjuster function.

[0005] When using the curtain hook with an adjuster function of Patent Document 1, a problem occurs in that the curtain body is tilted upward. This is because when the curtain hook is inserted into the curtain fastening part, a vertical misalignment occurs between the hook part that is attached to the curtain runner and the roughly U-shaped curved part that supports the end face of the curtain fastening part. This misalignment affects the hanging posture of the curtain and creates a tilt at the top of the curtain. This problem not only mars the appearance of the top of the curtain, but also widens the gap between the curtain rail and the top of the curtain, which is undesirable from the standpoints of soundproofing, light blocking, and room heat retention. The curtain hook of the present invention solves these problems.

[0006] Furthermore, conventional curtain hooks with a single-pronged insert rod tend to tilt left and right relative to the curtain, causing instability and spoiling the aesthetics.In addition, the weight of the curtain is placed on the single insert rod and the inserted curtain interlining, which raises concerns that hanging heavy curtains could cause deformation or damage to both. That is, to provide a curtain hook which minimizes the inclination of the upper part of a curtain, prevents the curtain hook inserted into the curtain from inclining left and right relative to the curtain, distributes and reduces the load on the curtain hook and the curtain interlining generated when the curtain is hung, and further has a position adjustment function. [Means for solving the problem]

[0007] This is a curtain hook for hanging a curtain on a rail, and has a two-part structure consisting of a main body and a hook portion connected to the main body, and the main body has left and right divided insertion rods arranged as the first insertion rod and the second insertion rod, and a ratchet portion with an adjuster function is installed between the first insertion rod and the second insertion rod, and the hook portion includes a hook for engaging with a curtain runner and a body portion, and the hook extends from the body portion, and the body portion branches to the left and right from a branch portion on the top surface of the hook, forming a V-shaped slit between them, and each branch has a claw portion at the bottom end, and the claw portion can engage with an engaging protrusion formed on the ratchet portion of the main body, thereby reducing the slope of the upper part of the curtain.

[0008] Preferably, the ratchet portion is a curtain hook having a structure that does not include a front wall and / or a rear wall, and has a thin plate thickness in the front-to-rear direction with the engaging projection exposed.

[0009] Also preferably, the curtain hook has an engaging projection formed on the ratchet portion that can pass downward through the slit provided on the upper surface of the hook. [Effects of the Invention]

[0010] The curtain hook of the present invention has a two-part structure consisting of a main body and a hook portion connected to the main body, the main body having left and right divided insertion rods arranged as a first insertion rod and a second insertion rod, a ratchet portion with an adjuster function installed between the first and second insertion rods, the hook portion including a hook for engaging with a curtain runner and a body portion, the hook extending from the body portion, the body portion branching into left and right from a branch portion on the top surface of the hook with a V-shaped slit formed between them and having a claw portion at the bottom end of each branch, the claw portion being engageable with an engaging protrusion formed on the ratchet portion of the main body, this ratchet structure providing a "position adjustment function (adjuster function)," and a structure that shortens the horizontal distance between the curtain engagement point and the ring engagement point, thereby "reducing the slope of the upper part of the curtain."

[0011] By reducing the slope of the top of the curtain, the top of the curtain becomes closer to vertical, improving the appearance. Also, by reducing the gap between the top of the curtain and the curtain rail, the light blocking effect is improved. This narrowing of the gap not only reduces the direct inflow of outside air, improving the room's heat retention effect, but also limits the range of outside sound transmission, improving the soundproofing effect inside the room. In other words, reducing the inclination of the upper part of the curtain contributes to improving the appearance, light blocking effect, indoor heat retention effect, and indoor soundproofing effect. Another drawback of the conventional single-legged insertion rod is that the curtain hook inserted into the curtain tends to tilt left or right relative to the curtain, making it unstable and unsightly. By dividing the insertion rod into two, the curtain and curtain hook are held firmly at a right angle, improving stability and aesthetics. With conventional curtain hooks with a single insertion rod, the weight of the curtain is placed on the single insertion rod and the inserted curtain interlining, which can cause deformation or damage to both when hanging a heavy curtain. However, with this invention, by using multiple insertion rods, the load is distributed, preventing deformation or damage to the curtain hook and curtain interlining.

[0012] Furthermore, a slit is provided on the upper surface of the hook, and the engaging protrusion formed on the ratchet portion can pass through the slit, and the slit is designed in a V-shape, thereby improving the adjuster function. This slit structure allows the hooks to be easily moved, making it easy to adjust the position of the curtain.

[0013] As shown in Figure 11, in a conventional curtain hook, when the curtain hook is hung from a curtain runner in its natural state, the hook claw engages with a ratchet, causing it to tilt by approximately 10 to 20 degrees depending on the step of the ratchet. Therefore, this tilt needs to be corrected. The curtain hook of the present invention can correct this tilt because the horizontal distance between the curtain hook point and the ring hook point is shorter, reducing the tilt of the upper part of the curtain.

[0015] The structure of the curtain hook in the first embodiment of the present invention will be described below.

[0016] FIG. 1 is a diagram showing a curtain hook according to a first embodiment of the present invention.

[0017] The curtain hook 100 of FIG. 1 has a two-part structure consisting of a main body 10 and a hook portion 50 connected to the main body 10. FIG. 2 shows the state when the main body 10 and the hook portion 50 are separated.

[0018] In FIG. 2, the main body 10 has an insertion rod divided into left and right halves, which are arranged as a first insertion rod 21 and a second insertion rod 22, and a ratchet portion 31 with an adjuster function is installed between the first insertion rod 21 and the second insertion rod 22.

[0019] The hook portion includes a hook 51 for engaging with a curtain runner and a body portion 52, and the hook 51 extends from the body portion 52. Body portion 52 branches to the left and right from branch portion 54 on the top surface of the hook, with a V-shaped slit 55 formed between them (Fig. 9), and each branch has a claw portion 53 at the bottom end. Claw portion 53 can engage with downward protrusion 32c formed on ratchet portion 31 of the main body. In other words, claw portion 53 is designed to mesh with downward protrusion 32c of the ratchet portion provided on the main body, and can reliably engage with the engaging protrusion when adjusting the position of the hook.

[0020] The first insertion rod 21 and the second insertion rod 22 are intended to be inserted into the fastening portion of the curtain, and after being inserted into the fastening portion of the curtain (not shown), the curtain is supported mainly by the inner surface 23 of the first insertion rod and the inner surface 24 of the second insertion rod.

[0021] As shown in FIG. 2, the ratchet portion 31 has a plurality of downward projections 32c formed continuously on both the left and right surfaces as engagement projections. The claw 53 is attached so as to embrace the upper part 32a of the ratchet part, and the claw has the function of engaging with the downward protrusion 32c of the ratchet part in a ratchet-like manner. This allows the hook to slide smoothly downward. This structure makes it easy to adjust the height of the curtain and provides a position adjustment function.

[0022] FIG. 10 is a side view of a conventional stand-alone curtain hook 300. The curtain hook 300 has a curtain engagement point (i) and a ring engagement point (h) that are aligned almost linearly with respect to the vertical axis, albeit with a slight tilt. In this way, when the curtain engagement point is close to the main body, the tilt of the upper part of the curtain is small. As a result, the hanging position of the curtain is almost an ideal vertical line. However, stand-alone curtain hooks do not have an adjuster function.

[0023] On the other hand, as shown in Figure 11, with a conventional hook 400 with an adjuster function, the curtain engagement point i and the ring engagement point h are not aligned linearly with respect to the vertical axis, causing the curtain hanging position to deviate from the ideal vertical line. Point g is the point at the same height as point h on the vertical axis passing through point i (point g is on the ideal vertical line). In other words, the distance between points g and h (hereinafter referred to as "distance gh") is the horizontal distance between the curtain engagement point i and the ring engagement point h. The shorter the distance gh, the less the slope of the upper part of the curtain. However, with conventional hooks with an adjuster function, the distance gh is long, so the slope of the upper part of the curtain becomes greater.

[0024] As shown in FIG. 7, the distance gh in the curtain hook 100 of the present invention is shorter than the distance gh in the conventional curtain hook 400. According to actual measurements, the distance gh of the conventional hook 400 with an adjuster function was approximately 13 mm, while the distance gh of the curtain hook 100 of the present invention was approximately 2 mm.

[0025] This shortening is achieved by dividing the insertion rod, which is originally one piece, into two pieces and installing a ratchet portion 31 with an adjuster function between them. In addition, the structure has been simplified by integrating the conventional hook neck, claw, and body.

[0026] By dividing the conventional single-leg insertion rod into two, the distance gh can be shortened, and furthermore, the instability of the curtain hook inserted into the curtain tilting left and right relative to the curtain can be eliminated.

[0027] As shown in Figure 12, in a conventional curtain hook 400, the hook claw portion 401, hook body portion 402, and hook neck portion 403 are aligned in a front-to-back direction, and the main rod portion 407 of the curtain hook 400 has a front wall 404 and a rear wall 405 in the ratchet portion 406, which increases the thickness of the plate in the front-to-back direction.

[0028] In contrast, in the present invention, these parts are integrated, and the functions of the claw and body are integrated into the neck of the hook, simplifying the structure. The functions of the front and rear walls are transferred to the hook. As shown in Figure 2, the hook neck (not shown) of a conventional hook is integrated with the claw 53 and body 52, and the conventional main rod in the present invention only functions as a ratchet, with the front and rear wall functions being in the hook, and the integrated structure shortens the distance gh. Therefore, the curtain hook of the present invention does not have a thicker front-to-rear direction compared to conventional ones.

[0029] The hook portion 50 includes a hook 51 for engaging with a curtain runner and a body portion 52, and the body portion branches into left and right branches from a branch portion 54, with claw portions 53 at the lower ends of each branch.

[0030] Therefore, the curtain hook of the present invention has a two-part structure consisting of a main body and a hook portion connected to the main body, and the main body has left and right divided insertion rods arranged as the first insertion rod and the second insertion rod, and a ratchet portion with an adjuster function is installed between the first insertion rod and the second insertion rod, and the hook portion includes a hook for engaging with the curtain runner and a body portion, and the hook extends from the body portion, and the body portion branches to the left and right from a branch portion on the top surface of the hook, forming a V-shaped slit between them, and has a claw portion at the lower end of each branch, and the claw portion can engage with an engaging protrusion formed on the ratchet portion of the main body, thereby reducing the slope of the upper part of the curtain.

[0031] As shown in FIG. 2, ratchet portion 31 of the curtain hook of the present invention does not have a front wall and / or a rear wall, downward engaging protrusion 32C of the ratchet portion is exposed, and the ratchet portion has a thin plate thickness in the front-to-rear direction.

[0032] In other words, the curtain hook of the present invention has the above-mentioned structure, which makes the distance gh shorter than that of conventional curtain hooks. Therefore, the curtain hook of the present invention has a shorter horizontal distance between the curtain engagement point and the ring engagement point, and the inclination of the upper part of the curtain is smaller. In addition, by dividing the conventional single-legged insertion rod into two, it is possible to eliminate the instability that occurs when the curtain hook inserted into the curtain tilts left or right relative to the curtain.

[0033] Figure 9 is a perspective view of the curtain hook of the present invention, viewed from above. A slit 55 is provided on the top surface of the hook body. The slit 55 is provided to make it easier for the claw portion 53 to open when the hook position is moved to a lower step. The hook structure is also large enough to completely enclose the ratchet portion.

[0034] Therefore, the curtain hook of the present invention has a slit on the upper surface of the hook, and the engaging projection formed on the ratchet portion can pass through the slit.

[0035] 3 shows a curtain hook according to a second embodiment of the present invention, in which the hook portion is located at the top.

[0036] Figure 4 shows a curtain hook according to a third embodiment of the present invention. The height of the curtain hook can be adjusted by sliding the ratchet-type hook portion 50 downward. It is slid further downward than in the second embodiment.

[0037] 5 shows a curtain hook according to a fourth embodiment of the present invention, which is slid further downward than in the third embodiment.

[0038] 6 shows a curtain hook according to a fifth embodiment of the present invention, which is slid further downward than in the fourth embodiment.

[0039] By using the curtain hook of the present invention, the horizontal distance between the curtain engagement point and the ring engagement point is shortened, improving the appearance and improving the soundproofing, light blocking, room heat retention, etc. In other words, we provide a curtain hook that has a position adjustment function while minimizing the slope of the upper part.
