Description

AREA OF INVENTION

[0001] The present invention / disclosure relates to a hook device for a door curtain of a vehicle. BACKGROUND

[0002] As in Fig. 1 and Fig. Figure 2 shows a door glass installed on a door 120 of a vehicle, and a door curtain 122 is installed to cover the door glass.

[0003] The door curtain 122 is used to adjust lighting or to protect a passenger's privacy. When the door curtain 122 is extended from the door 120, its upper end is secured and attached to the door 120, thus maintaining an operational state (e.g., extended state). The door curtain 122 is secured by allowing a shadow rod 122a, installed at the upper end of the door curtain 122, to be locked to a hook device 110, which is installed on a door panel 121.

[0004] The hook assembly 110 comprises a hook body 111, to which the door curtain is attached, and a hook pin 112, which is attached to the door panel 121 of the door 120 in order to attach the hook body 111 to it. The hook pin 112 is attached to the door panel 121 by means of a base 112a and a handle part 112b, which are formed on the hook pin 112. The hook body 111 is formed with a base 111a and a fastening part 111d, which extends above the base 111a, and a curtain fastening part 111b, which has the door curtain 122 attached to it, is formed below the base 111a. In the state in which the hook pin 112 is attached to the door panel 121, the hook body 111 is temporarily attached by pressing the hook pin 112 (e.g., the hook body 111) from bottom to top (see figure). Fig. 3A). The provisionally fastened state is a state in which an upper section of the fastening part 111d is inserted into the handle part 112b, and a state before a lower section of the fastening part 111d is inserted into the handle part 112b (see, e.g., distance C in Fig. 3A), and the handle part 112b maintains a state perpendicular to the base 112a of the hook pin 112 like an L-line.

[0005] Then, when the hook body 111 is fully attached (see below) Fig. 3B), the fastening part 111d is inserted into the handle part 112b, and a coupling part 111c of the hook body 111 and a coupling part 112c of the hook pin 112 are coupled, and the handle part 112b is opened outwards by an angle α or an angle β (see line L'), and therefore the hook pin 112 is not separated from the door panel 121 and is attached to it.

[0006] However, according to the technology referred to, the hook device 110 has a non-uniform fastening force for attaching the hook pin 112 to the door panel 121, depending on the size of a through-hole formed in the door panel 121 and the thickness distribution (e.g., change in the through-hole diameter) of the door panel 121.

[0007] Furthermore, because the hook body 111 is to be attached upwards so that the handle part 112b can be open, the fastening force is required to an excessive degree, and the setup is difficult.

[0008] Furthermore, the fastening force and a load (force of the door curtain, which is pulled (e.g. wound) into the door) act simultaneously in opposite directions on the hook pin 112, so that a phenomenon occurs in which the hook device 110 is separated from the door panel 121 or the hook device 110 is damaged when the door curtain 122 is attached to the hook device 110.

[0009] Another known hook device is disclosed in US 6 324 732 B1. EXPLANATION OF THE INVENTION

[0010] The present invention / disclosure relates to a hook device (e.g., hook arrangement) for a vehicle door curtain for attaching a door curtain installed on a vehicle door. Particular embodiments relate to a hook device for a vehicle door curtain that simplifies assembly, provides a uniform fastening force, and prevents the door curtain from being separated or damaged during use.

[0011] Embodiments of the present invention / disclosure can solve problems associated with the related technology, and one embodiment of the present invention / disclosure provides a hook device for a vehicle door curtain which can absorb a variation (e.g. distribution) in the size of a through-hole formed in a door panel (e.g., which can be used with through-holes of different sizes) in order to exert a constant fastening force.

[0012] A hook device for a vehicle door curtain, installed on a door panel and used to secure and fasten the upper end of the door curtain when extended from the door, comprises: a hook body having a mounting part and a mounting wing part for penetrating a through-hole formed in the door panel, and a hook pin having an upper end articulated to an upper section of the hook body, wherein, when an upper section of the hook pin can be fully inserted into the hook body, a portion of the hook body can be open, allowing the hook body to be locked to the circumference of the through-hole and thus secured to the through-hole. The hook pin has an insertion part that is inserted into an insertion notch (e.g., an insertion groove) formed in the mounting part.The insert part is formed with a mounting projection on both of its side surfaces to protrude in a longitudinal direction of the vehicle. When the insert part is inserted into the insertion notch of the mounting part, the mounting projection is configured to push the mounting wing part outwards and open it outwards, thus changing the amount of overlap between an inner surface of the insertion notch and the mounting projection to absorb any play in the longitudinal direction of the vehicle.

[0013] The hook body may, for example, have a base which contacts a lower surface of the door panel, the fastening part which is formed above the base and is positioned to penetrate the through-hole which is formed in the door panel, and the fastening wing part which extends downwards from an upper end of the fastening part, and, if the upper section of the hook pin can be / is fully inserted into the hook body, the fastening wing part may be locked to the circumference of the through-hole, while the fastening wing part may be open, and therefore the hook body may be attached to the through-hole.

[0014] The hook device for the door curtain may, for example, further include an extension (e.g., continuation or extension) which extends downwards from one end of the base, and a curtain fastening part which extends from a lower end of the extension, to which the upper end of the door curtain is snapped and fastened.

[0015] The fastening wing part can, for example, be formed with an upper inclined surface whose width increases downwards from a position that is at a distance from the upper end of the fastening wing part, and a lower inclined surface whose width decreases downwards from a lower end of the upper inclined surface, and, if the fastening wing part can be open in the longitudinal direction of the vehicle, the lower inclined surface contacts the circumference of the through-hole closely and the hook body can be attached to the through-hole.

[0016] ZB, the hook pin also has a lever part which extends downwards from a lower end of the insertion part.

[0017] The hook pin can, for example, have a rotating shaft formed at an upper end of the insertion part, the hook body has a shaft insertion hole in the longitudinal direction of the vehicle formed at the upper end of the fastening part, and the rotating shaft can be fitted (e.g., mounted) into the shaft insertion hole, and the hook pin can be rotatably coupled to the hook body.

[0018] The lever part can be shaped to be inclined downwards, to face an exterior of the vehicle in a lateral direction with respect to the insertion part.

[0019] If the lever part can be actuated in a state in which the fastening part can be inserted into the insertion part and provisionally attached to it, for example, the insertion part can be fully attached to the insertion notch of the fastening part while the hook pin rotates towards the interior of the vehicle.

[0020] A receiving notch, configured to receive the lever part, may for example be formed on the extension.

[0021] For example, a coupling projection may be formed at an upper end of the lever part, and, if the lever part can be inserted into the receiving notch, a coupling hole into which the coupling projection can be inserted may be formed in one side of the base.

[0022] The hook device for the door curtain may further comprise a bearing part (e.g., retaining part) which extends downwards from the upper end of the fastening part towards the interior of the vehicle in the lateral direction, wherein, when the fastening part penetrates the through-hole, a lower end of the bearing part may be locked to the circumference of the through-hole, while the lower section of the bearing part may be retracted towards the exterior of the vehicle in the lateral direction, and the hook body may therefore be attached to the through-hole.

[0023] According to the hook device for the door curtain of the vehicle according to embodiments of the present invention / disclosure, which has the above configuration, it is possible to absorb the scattering of the through-hole formed in the door panel only by attaching the hook body to the hook pin, thereby preventing the play of the hook device in the door panel and preventing the phenomenon in which the hook device can be (detached) from the door panel or the hook device can be damaged.

DETAILED DESCRIPTION

[0024] In the following, a hook device for a door curtain of a vehicle according to embodiments of the present invention / disclosure is described in detail with reference to the accompanying drawings.

[0025] Referring to Fig. Figures 4 to 9 comprise a hook device for a vehicle door curtain according to embodiments of the present invention / disclosure: a hook body 11, which is attached to the door panel 21 by passing through a through-hole 21a formed in the door panel 21, and a hook pin 12, which has an upper end that is articulated to an upper section of the hook body 11, and which opens the hook body 11 outwards (e.g., to the outside) when it is inserted into the hook body 11, and, when the hook pin 12 can be inserted into the hook body 11, the hook body 11 can be attached to the through-hole 21a, while it is open outwards (e.g., to the outside) in the hook device for the vehicle door curtain, which is installed on a door panel 21 to allow an upper end of the door curtain, which is extended from a door, to be locked. to be.

[0026] The hook body 11 can be installed to penetrate the through hole 21a formed in the door panel 21.

[0027] The base 11a contacts a lower surface of the door panel 21. Because the base 11a is shaped to be larger than the through-hole 21a, the base 11a cannot penetrate the through-hole 21a and can be positioned to contact the lower surface of the door panel 21. A coupling hole 11aa, into which a coupling projection 12c of the hook pin 12, which will be described later, is inserted, can be formed at an end of the base 11a that is positioned outside the vehicle or in a section adjacent to it.

[0028] An extension 11c can be shaped to extend downwards from one side of the base 11a. The extension 11c can be shaped to extend downwards from the end of the base 11a that is positioned outside the vehicle.

[0029] A receiving notch 11ca, configured to receive and secure a lever part 12b of the hook pin 12, which will be described later, can be formed on a rear surface of the extension 11c, i.e. a surface of the extension 11c which faces the outside of the vehicle.

[0030] A curtain fastening part 11b can be positioned below the base 11a to secure the upper end of the door curtain. The curtain fastening part 11b, as a lower end of the extension 11c, can be shaped to extend into the vehicle to allow a shadow rod installed at the upper end of the door curtain to be locked in place, thereby securing the upper end of the door curtain.

[0031] A fastening element 11d can be formed on an upper section of the base 11a. The fastening element 11d extends upwards from the base 11a and is positioned through the through-hole 21a formed in the door panel 21. The base 11a and the fastening element 11d are positioned below and above the door panel 21, respectively (e.g., the base 11a is positioned below and the fastening element 11d above the door panel 21).

[0032] An insertion notch (e.g. insertion groove) 11da, which is configured to receive an insertion part 12a of the hook pin 12, and a shaft insertion hole 11db, into which a rotating shaft 12d, which is formed at an upper end of the hook pin 12, can be inserted, are formed in the fastening part 11d in a longitudinal direction of the vehicle.

[0033] A fastening wing part 11e can be formed on one side surface of the fastening part 11d, preferably on both side surfaces of the fastening part 11d. The fastening wing part 11e has an upper end which is connected to the fastening part 11d, and a side surface and a lower end which are formed in a state of separation from the fastening part 11d. Therefore, the fastening wing part 11e has a structure in which a lower end of it can be open outwards around a fixed upper end.

[0034] The fastening wing part 11e has an inclined surface 11ea, 11eb formed on an outer surface thereof. The outer surface of the fastening wing part 11e can be formed with an upper inclined surface 11ea, the width of which increases downwards from a position that is a distance from the upper end of the fastening wing part 11e, and a lower inclined surface 11eb, the width of which decreases downwards from a lower end of the upper inclined surface 11ea.

[0035] When the fastening part 11d is inserted into the through hole 21a, the upper inclined surface 11ea allows (e.g. enables) the fastening wing part 11e to enter the fastening part 11d, so that the fastening part 11d can be easily inserted into the through hole 21a.

[0036] The lower inclined surface 11eb allows the lower inclined surface 11eb to be supported (e.g. held, e.g. braced) by means of a circumference of the through hole 21a, so that the fastening part 11d retains the state of being fastened to the through hole 21a.

[0037] Furthermore, the fastening part 11d can be formed with a bearing part (e.g., retaining part) 11dc, which extends downwards from an upper end of the fastening part 11d. The bearing part 11dc extends, in order to be inclined downwards into the vehicle, in a lateral direction between two fastening wing parts 11e. The bearing part 11dc can be shaped to be inclined in the lateral direction into the vehicle from an upper end towards a lower section thereof.

[0038] The bearing part 11dc has a lower end that contacts one side of the through-hole 21a to allow the hook assembly 10 to absorb the clearance in the width direction of the vehicle. Because only one upper end of the bearing part 11dc is attached to the mounting part 11d, one lower end of it has the same shape as a free end of a cantilevered arm (e.g., a cantilever). Therefore, the bearing part 11dc can be elastically deformed according to the size of the through-hole 21a, and the lower end of the bearing part 11dc can be retracted to contact the circumference of the through-hole 21a when the hook body 11 penetrates the door panel 21. Therefore, when the hook device 10 is mounted / set up, the bearing part 11dc allows the hook body 11 to be attached to the through hole 21a in a direction different from the mounting wing part 11e, and absorbs the play of the vehicle in the lateral direction.

[0039] The hook pin 12 can be rotatably installed on the hook body 11, and when the hook pin 12 is inserted into the hook body 11 by means of rotation, the hook body 11 retains the state of being attached to the door panel 21.

[0040] The insertion part 12a can be inserted into the fastening part 11d of the hook body 11. The insertion part 12a allows the fastening wing part 11e to be open when the insertion part 12a is inserted into the insertion notch 11da formed in the fastening part 11d, thus preventing the hook body 11 from being separated from the through hole 21a. At this point, the insertion part 12a allows the fastening wing part 11e to open in a direction perpendicular to the direction in which the insertion part 12a is inserted.

[0041] For this purpose, a (e.g., an associated) fastening projection 12aa, which is configured to allow the insert part 12a to be open to the outside (e.g., to the inside) of the fastening wing part 11e, can be shaped to protrude from both side surfaces of the insert part 12a.

[0042] The rotating shaft 12d can be formed at an upper end of the insertion part 12a. The rotating shaft 12d can be inserted into the shaft insertion hole 11db, and the hook pin 12 therefore becomes a center of rotation which is rotated by the hook body 11.

[0043] The lever part 12b can be shaped to extend downwards from a lower end of the insert part 12a.

[0044] The lever part 12b can be shaped to be inclined towards the outside of the vehicle in the lateral direction with respect to the insert part 12a.

[0045] When the insert part 12a presses the lever part 12b in the state in which the fastening part 11d is inserted and provisionally fastened, the hook pin 12 rotates around the rotating shaft 12d to be / become fully fastened.

[0046] Because the lever part 12b is not shaped to be parallel with an upper section of the insertion part 12a and is shaped at a certain angle, the lever part 12b can be in a state of being separated from the extension 11c in the state in which the hook pin 12 is provisionally attached, but when the lever part 12b is actuated in the direction of the extension 11c, the hook pin 12 rotates, and therefore the lever part 12b can be inserted into the receiving notch 11ca of the extension 11c as far as possible to complete the attachment.

[0047] An upper end of the lever part 12b can be formed with the coupling projection 12c, which is configured to prevent the lever part 12b from being separated from the receiving notch 11ca while maintaining its inserted state in the receiving notch 11ca when the lever part 12b is inserted into the receiving notch 11ca. The coupling projection 12c can be inserted into the coupling hole 11aa so that the lever part 12b maintains its inserted state in the receiving notch 11ca.

[0048] The hook device according to embodiments of the present invention / disclosure, which have the above configuration, can be provisionally mounted / set up by penetrating the through-hole 21a of the door panel 21 in a state in which the hook pin 12 is provisionally attached to the hook body 11 (cf. Fig. 6) In the provisionally fastened state, in which the fastening part 11d of the hook body 11 is inserted into the insertion part 12a of the hook pin 12 (e.g., in which the insertion part 12a of the hook pin 12 is inserted into the fastening part 11d of the hook body 11) and the lever part 12b of the hook pin 12 is not inserted into the receiving notch 11ca of the hook body 11, the device of the hook body 11 and the hook pin 12 can be provisionally mounted / set up by means of penetrating the through hole 21a of the door panel 21.

[0049] The lever part 12b of the hook pin 12 can then be rotated so that it can be inserted into the receiving notch 11ca. Once the lever part 12b is inserted, the hook pin 12 can be fully attached to the hook body 11, and the coupling projection 12c can be inserted into the coupling hole 11aa.

[0050] In particular, since the insert part 12a is fully inserted into the fastening part 11d, the fastening projection 12aa, which is formed on both side surfaces of the insert part 12a, pushes the fastening wing part 11e outwards. When the fastening wing part 11e is pushed outwards, it can open outwards, and a circumference of the lower inclined surface 11eb of the fastening wing part 11e contacts the through hole 21a of the door panel 21, and therefore the assembly of the hook body 11 and the hook pin 12, that is, the hook assembly 10am, can be fastened to the fastening hole 21a of the door panel 21.

[0051] If the hook assembly 10 is mounted / set up by rotating the lever part 12b, the fastening wing part 11e can be positioned in front of it (e.g., ready to be opened outwards by means of the fastening projection 12aa), but the lower inclined surface 11eb of the fastening wing part 11e can be restricted by the through-hole 21a, thus exerting a strong fastening force even with a lower actuating force. If the lever part 12b is rotated by pressing its lower end, the lever part 12b can be positioned in a location separate from the rotating shaft 12d, instead of on a section where the fastening projection 12aa is formed, thus exerting the strong fastening force, while the hook body 11 and the hook pin 12 are fully fastened with the lower actuating force by means of a lever principle.

[0052] Furthermore, according to embodiments of the present invention / disclosure, it is possible to prevent play regardless of the size of the through-hole 21a and to exert the constant fastening force and to absorb the size variation of the through-hole 21a by allowing the hook device 10 to make close contact with the door panel 21.

[0053] Fig. 10A to 10C represent a principle of absorbing the distribution of the size of the through-hole 21a in the L-direction (lateral direction of the vehicle). Fig. 10A represents a state in which the through-hole 21a has been machined to be smaller than a fixed value, Fig. 10B represents a state in which the through-hole 21a has been machined to be at the fixed value, and Fig. 10C represents a state in which the through hole 21a has been machined to be larger than the fixed value.

[0054] As described above, even if the dimensions of the through-hole 21a are shaped differently due to manufacturing variations, the degree to which the bearing part 11dc is open can be adjusted, thus enabling tight fastening. In other words, the Fig. 10A to 10C each assigned an amount of overlap as C 11 , C 12 and C 13 Since the degree to which the bearing part 11dc is retracted varies depending on the size of the through-hole 21a, the hook device 10 can be attached to the through-hole 21a without any play, while the amount of overlap between the bearing part 11dc and the through-hole 21a varies. For example, if the through-hole 21a is larger than the fixed value (see below) Fig. 10A) compared to a case in which the through hole 21a is shaped at the fixed value (cf. Fig. 10B), the bearing part 11dc may be less retracted, thus eliminating the play. Conversely, if the through-hole 21a is shaped to be larger than the fixed value (see ), Fig. 10C), the bearing part 11dc is further withdrawn, thereby removing the play.

[0055] Fig. 11A to 11C represent a principle of absorbing the scattering of the size of the through-hole 21a in a T-direction (longitudinal direction of the vehicle). Fig. 11A represents a state in which the through hole 21a has been machined to be smaller than the fixed value, Fig. 11B represents a state in which the through-hole 21a has been machined to be at the fixed value, and Fig. 11C represents a state in which the through hole 21a has been machined to be larger than the fixed value.

[0056] If the through-hole 21a is shaped to be smaller than the fixed value (see Fig. 11A), the lower inclined surface 11eb closely contacts the circumference of the through-hole 21a, while the fastening wing part 11e is less open outwards (section A of the Fig. 11a) compared to a case in which the through hole 21a is shaped at a fixed value (cf. Fig. 11B), and the amount of overlap between an inner surface of the insertion notch 11da and the fastening projection 12aa (C 21 ) to its maximum in order to absorb the play in the longitudinal direction of the vehicle. When the size of the through-hole 21a is at the fixed value, the inclined surface 11eb contacts the circumference of the passage 21a tightly, while the mounting wing part 11e opens further outwards (section A of the Fig. 11B) and the amount of overlap between the inner surface of the insertion notch 11da and the fastening projection 12aa decreases. If the size of the through-hole 21a is shaped to be larger than the fixed value (see Fig. 11C), the lower inclined surface 11eb contacts the circumference of the through hole 21a, while the fastening wing part 11e is open much further outwards (section A of the Fig. 11C) and the overlap between the inner surface of the insertion notch 11da and the fastening projection 12aa does not occur and the inner surface of the insertion notch 11da and the fastening projection 12aa are in contact (section B of the Fig.11C). As described above, even if the dimensions of the through-hole 21a vary due to manufacturing tolerances, it is possible to absorb the play in the longitudinal direction of the vehicle without any separate adjustment. In other words, the mounting projection 12aa opens the mounting wing part 11e outwards during the process of inserting the insert part 12a into the mounting part 11d by actuating the lever part 12b, and the lower inclined surface 11eb makes close contact with the circumference of the through-hole 21a and can be supported (or held) by it. Therefore, the degree to which the mounting wing part 11e is open can be adjusted (or adjusts itself automatically), thus enabling a play-free fastening, even if the dimensions of the through-hole 21a vary due to manufacturing tolerances.

[0057] As described above, even if the sizes of the through-hole 21a are shaped differently due to manufacturing variation (e.g., production distribution), this is absorbed in the process in which the hook device 10 is mounted / set up on the door panel 21, and therefore the clearance between the hook device 10 and the door panel 21 does not occur.
