Description

[Technical Field]

[0001] This invention relates to a hook that can be attached to the wall of a house or the like using a pin, and more particularly to a wall-mounted hook that is designed so that the pinhole remaining on the wall when the hook is removed is not noticeable. [Background technology]

[0002] The walls of a typical home are constructed with wallpaper pasted on the surface of gypsum board. When attaching hooks to such walls, hooks that are fixed by inserting pins are widely used. However, when conventional hooks are removed, there is a problem in that pin marks remain on the wall after the pin is removed, which mars the appearance of the wall.

[0003] To solve this problem, efforts have been made to use thin pins to make the pin marks smaller. For example, Patent Document 1 (JP 2015-2833 A) discloses a configuration in which the diameter of each pin is made smaller than when a single thick pin is used by distributing the load using multiple pins, thereby making the pin marks smaller and less noticeable. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2015-2833 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, even when using pins with such small diameters, the pins are inserted into the wall surface perpendicularly or at a relatively large angle, so the pin marks are clearly visible depending on the viewing angle.The purpose of this invention is to make the pin marks less noticeable when the hook that is fastened to the wall surface is removed. [Means for solving the problem]

[0006] The wall-mounted hook of this invention is a hook that is attached to a wall surface and can hang an object on, and is equipped with a hook body with at least one pin hole, and a pin that is inserted into the pin hole and driven into the wall surface.The hook body has a mounting base with a contact surface with the wall surface, and a hanging portion extending from the mounting base, and the pin hole extends vertically when viewed from the front and is angled at an angle of 20 degrees to 30 degrees with respect to the contact surface when viewed from the side.

[0007] In a wall-mounting hook configured as described above, the pin hole is formed at an inclination angle of 20 to 30 degrees relative to the contact surface, allowing the pin to be inserted obliquely at a shallow angle of 20 to 30 degrees relative to the wall surface. As a result, the pin hole is oblique to the wall surface, with an inclination of approximately 80 to 70 degrees relative to the wall surface. Because hooks are typically installed higher than eye level, observers often look slightly upward at the wall surface. When the pin hole has such a large inclination angle relative to the wall surface, it becomes difficult for the observer's line of sight to coincide with the direction of the pin hole. Therefore, the pin hole is less visible from the observation direction, allowing the hook to be removed without damaging the appearance of the wall surface.

[0008] If the inclination angle of the pin hole is less than 20 degrees, the pin may not dig into the wall sufficiently, resulting in a reduced fixing force. On the other hand, if it exceeds 30 degrees, the opening of the puncture mark will be larger relative to the observation direction, making it easier to see. In this device, "front" refers to the direction facing the wall when the abutment surface of the hook body is abutting the wall. "Side" refers to the direction perpendicular to the horizontal direction relative to the front.

[0009] In addition, the wall mounting hook of the present invention is characterized in that the diameter of the pin is between 0.6 mm and 0.7 mm, and the length of the pin hole is between 40% and 80% of the effective length of the pin.

[0010] With this wall-mounting hook, by setting the pin diameter to between 0.6 mm and 0.7 mm, the pin marks are small and the aesthetics of the wall are less likely to be marred even after the hook is removed. If the pin diameter is less than 0.6 mm, it is likely to bend when inserted, which may hinder installation and retention. If the pin diameter exceeds 0.7 mm, the pin marks are large and more noticeable after the hook is removed.

[0011] Furthermore, by setting the length of the pin hole to a ratio of 40% to less than 80% of the effective length of the pin, the pin is appropriately guided by the pin hole and stably inserted into the wall surface. Therefore, even if the pin diameter is thin, between 0.6 mm and 0.7 mm, the pin can be prevented from bending during insertion while ensuring sufficient holding force. If the length of the pin hole is less than 40% of the effective length of the pin, the pin will not be adequately guided, making it more likely to bend and bend during insertion. Furthermore, if the length of the pin hole is more than 80%, the majority of the pin will remain within the hook body, and the length inserted into the wall will be insufficient, reducing the fixing force and making it difficult to stably hold the hook body. [Effects of the Invention]

[0012] With the wall mounting hook of this invention, the pin marks are less noticeable when the hook is removed, maintaining the aesthetic appearance of the wall surface. In addition, the pin can be prevented from bending when inserted while ensuring sufficient holding force. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] In this specification, "front" refers to the direction facing the wall when the abutment surface of the hook body is in contact with the wall. "Side" refers to the direction perpendicular to the front. The effective length of the pin refers to the total length of the needle-shaped member that can be inserted into the wall through the pin hole, excluding the pin head. Hereinafter, an embodiment of the present invention will be described with reference to Figures 1 to 4.

[0015] FIG. 1 is an exploded perspective view of a wall-mounting hook 100 according to the present invention, and FIG. 2 is an exploded front view of the wall-mounting hook 100 according to the present invention. As shown in FIGS. 1 and 2, the wall-mounting hook 100 according to the present invention comprises a hook body 10 and a pin 20 attached to the hook body 10. The hook body 10 has a mounting base 11 that is attached to a wall W (shown in FIG. 4) and a hanging portion 12 that extends forward from the mounting base 11. The hanging portion 12 is formed in a hook shape capable of holding an object to be hung, such as daily necessities, and has an inner reinforcing portion 12a on its inside that reinforces the hanging portion 12. The mounting base 11 has a pin hole 13 (in FIG. 2, the pin hole 13 is formed inside the mounting base 11, and is therefore shown by a dashed line for convenience of illustration). A pin 20 is inserted into the pin hole 13 and inserted into the wall W, thereby fixing the hook body 10 to the wall W.

[0016] In this embodiment, two pin holes 13 are provided in the upper row and one in the lower row of the mounting base 11, and two pins 20 are inserted into the upper row and one pin in the lower row, corresponding to the positions of the pin holes 13. By providing multiple pin holes 13 in this manner, the hook body 10 can be stably attached to the wall surface W. In addition, this embodiment is provided with a cap 30 that covers the hook body 10 and the pin 20, and this cap 30 is provided to enhance decorativeness and safety.

[0017] Figure 3 is an exploded side view of the wall mounting hook 100 of the present invention. In Figure 3, the pin hole 13 is formed inside the mounting base 11, and is therefore shown by a dashed line for convenience of illustration. As shown in Figure 3, the mounting base 11 is formed with an abutment surface 14 that abuts against the wall surface W. In addition, an outer reinforcing portion 12b is provided on the outside of the hanging portion 12 to reinforce the hanging portion.

[0018] The pin hole 13 provided in the mounting base 11 extends in the vertical direction Y in the front view shown in FIG. 2 and is inclined at an angle θ with respect to the abutment surface 14 in the side view shown in FIG. 3. In this embodiment, the angle θ is 25 degrees. As a result, the pin 20 is inserted obliquely at a shallow angle θ with respect to the wall surface W, rather than perpendicularly. Due to this inclination of the insertion direction, the pin 20 leaves an inclined mark on the wall surface. As a result, the pin 20 leaves an inclined mark at 75 degrees with respect to the wall surface. Typically, hooks are installed at a position higher than human eye level, so the observer's line of sight is directed upward at the wall surface from below. Since the opening direction of the pin 20 is less likely to coincide with the observation direction, the pin 20 is less likely to be visible, and the aesthetic appearance of the wall surface is less likely to be impaired even after the hook is removed.

[0019] The inclination angle θ of the pin hole 13 is preferably set in the range of 20 degrees or more and 30 degrees or less. If the angle θ is less than 20 degrees, the pin 20 may not dig into the wall surface sufficiently, which may reduce the fixing force. On the other hand, if the angle θ is more than 30 degrees, the opening of the puncture mark becomes easily visible in the observation direction.

[0020] Figure 4 is an enlarged cross-sectional view taken along line II-II in Figure 2, showing the wall mounting hook 100 of the present invention attached to a wall with the cap 30 attached. As shown in Figure 4, the diameter D of the pin 20 in this embodiment is 0.65 mm. By making the diameter D of the pin 20 this small, the puncture mark left after the pin 20 is removed is small, and the aesthetic appearance of the wall surface W is less likely to be marred.

[0021] It is desirable to set the diameter D of the pin 20 in the range of 0.6 mm to 0.7 mm. If the diameter D of the pin 20 is less than 0.6 mm, it may be easily bent during insertion, which may hinder application and retention. If the diameter D of the pin 20 exceeds 0.7 mm, the puncture mark will be large and will be more noticeable after removal.

[0022] In this embodiment, the pin 20 has an effective length of 20 mm. The effective length of the pin 20 is usually around 20 mm for this type of hook, and is preferably between 15 mm and 25 mm from the viewpoint of ease of installation and holding power.

[0023] 4, in this embodiment, the length L1 of the pin hole 13 provided in the upper section of the mounting base 11 is formed to be approximately 50% of the effective length L2 of the pin 20. The length L1 of the pin hole 13 in the lower section is formed to be approximately 65% ​​of the effective length L2. The length L1 of the pin hole 13 is preferably set to be in the range of 40% to less than 80% of the effective length L2 of the pin 20. This range allows the pin 20 to be appropriately guided by the pin hole 13 and prevents bending during insertion. This allows the pin to be stably inserted into the wall surface W, even when the pin diameter D is as small as 0.65 mm, as in this embodiment, and ensures sufficient holding force.

[0024] If the length L1 of the pin hole 13 is less than 40% of the effective length L2 of the pin 20, the guiding effect will be insufficient and the pin 20 may bend when inserted. If it is 80% or more, most of the pin 20 will fit within the pin hole 13, and the insertion length into the wall surface W will be insufficient, which may reduce the fixation force.

[0025] The following describes how to use the wall-mounting hook 100 of the present invention. First, the abutment surface 14 of the hook body 10 is placed against the wall W, and the pin 20 is inserted into the pin hole 13 of the mounting base 11. The user then uses a hard object such as a coin to push the head of the pin 20, causing the pin 20 to penetrate the wall W through the pin hole 13. This secures the hook body 10 to the wall W, allowing the object to be hung stably from the hanging portion 12. Furthermore, by attaching the cap 30, the head of the pin 20 is not exposed to the outside, improving safety and maintaining an aesthetically pleasing appearance. [Explanation of symbols]
