<i> The present invention relates to a door glass grip for vehicles. More particularly, the present invention relates to a door glass grip for vehicles, in which a supporting nut having a plate nut structure and an auxiliary nut having a lock nut structure, being embedded respectively in a main body connected to a slider and in one of a pair of supporting plates that support a door glass, are separately structured such that the manufacturing process can be simplified by manufacturing the nuts without processing of a screw thread, damage of the door glass or the slider can be prevented by restricting further fastening when a fastening torque of greater than a predetermined degree is applied by the plate nut, and also a bolt which is screw-connected to the auxiliary nut having the lock nut structure can be prevented from being unlocked by external factors such as vibration. [Background Art]

<2> In general, a door glass grip refers to a part holding, supporting, and connecting with a slider a door glass which is mounted in a door of a vehicle and moved up and down by a door glass regulator to thereby open and close a window of the vehicle.

<3> An example of such a door glass regulator will be briefly explained with reference to the accompanying drawings.

<4> As shown in Fig. 1 to Fig. 4, conventional door glass regulators are largely divided into an arm-type regulator and a cable-type regulator. First, the arm-type door glass regulator illustrated in Fig. 1 comprises a main arm 100.In the main arm 100, a sector gear 102 is mounted at a lower end apparent and supported by a door inner panel or a modularization panel (not shown) through a supporting pin 104. As the sector gear 102 is rotated by a motor 105 fixed to the door inner panel or the modularization panel, the main arm 100 is rotated with respect to the supporting pin 104. A sub arm 106 of the arm-type regulator is supported by a pin 107 in the middle of the main arm 100 across the main arm 100, while supporting a sub arm slider 106 mounted at a lower end approximately to be movable in a horizontal direction along a sub arm rail 108 which is fixed to the door inner panel or the modularization panel. The arm-type regulator further comprises a guide rail 110 that is a mounting member moved up and down under the guidance of sliders 109 and 109 respectively mounted at upper ends of the main arm 100 and the sub arm 106, a vehicle door glass grip 40 fixed to both ends of the guide rail 100 through bolts 112 by its lower end and equipped with an insertion recess (not shown) at its upper end, and a door glass 4 fixed to the insertion recesses by bolts 54.

<5> The above-structured arm-type door glass regulator operates as follows. As the sector gear 102 is rotated by the motor 105, the main arm 100 is pivoted up and down about the supporting pin 104.When the main arm 100 is thus axial Iy pivoted, the pin 107 is displaced in association with the pivoting of the main arm 100. according, the sub arm slider 106 mounted at the lower end of the sub arm 106 is horizontally moved along the sub arm rail 108.

<6> Subsequently, the slider 109 formed at the upper end of the main arm 100 is rotated about the pin 107 and, as a result, the sliders 109 and 109 of the main arm 100 and the sub arm 106 are both horizontally slid along the guide rail 110. Finally, the guide rail 110 can be moved up and down in a horizontally balanced position, thereby moving the door glass 4 fixed by the door glass grip 40 in an up and down direction.

<7> On the other hand, the cable-type regulator 10 shown in Fig. 2 to Fig. 4 is fixed to a door frame 3 formed between an outer panel 2 and an inner panel (not shown), by a multiple of bolts 20 dedicatedly provided as fixing means.

<8> The cable-type door glass regulator 10 comprises a vertical member 11 of which upper and lower parts are fixed to the door frame 3 by fixing brackets 21 and bolts 20, a slider 12 slid up and down along the vertical member 11 and fixed to a lower end of a door glass 4, a motor 13 having a winding roller 13a, and a wire cable 14 wound on the winding roller 13a and fixed to the slider 12 by passing through upper and lower ends of the vertical member 11 by both ends

<9> A rotation roller (not shown) is mounted to both ends of the vertical member 11, to guide rotation of the wire cable 14 that moves the slider 12 up and down as rotated by the motor 13.

<io> In addition, the door frame 3 has several holes arranged sporadically, which are large enough for an operator to easily mount component parts such as the door glass regulator 10 therethrough.

<ii> The above-structured cable-type door glass regulator 10 operates as follows. When the operator pushes an operation button (not shown) to open the door glass 4, the winding roller 13a is rotated forward by the motor 13. Then, the wire cable 14 wound on the winding roller 13a is rotated in the same direction as the winding roller 13a. According, the slider 12 fixed to the both ends of the wire cable 14 is moved down along the vertical member 11 fixed to the door frame 3.

<i2> It is certain that the above processes are performed in the opposite manner in order to close the door glass 4.

<i3> The mounting processes of the conventional cable-type door glass regulator 10 will be explained. First, the vertical member 11 is placed between the outer panel 2 of the door 1 and the door frame 3, and the fixing brackets 21 formed at the upper and lower parts of the vertical member 11 are corresponded to fixing holes formed at the door frame 3 so that the door glass regulator 10 can be fixed from the outside of the door frame 3 using the multiple of bolts 20.

<i4> Here, the door glass 4 needs to be connected to the slider 12 slidably in an up and down direction. To this end, a door glass grip 40 for vehicles is provided in such a manner that one end fixing fixedly supports the door glass 4 while the other end is fixed to the slider 12.

<15> The conventional door glass grip 40 is generally formed by injection molding of plastic, and comprises a main body 42.At one end of the main body 42, a pair of supporting plates 44 are arranged in parallel at a predetermined interval, and a nut 50 is embedded in the supporting plates 44 to fix the door glass 4. Also, a nut 48 is embedded in the other end of the main body 42 that supports a bolt fixed to the slider 12.

<16> Reference symbols 41 and 43 in Fig. 4 denote cut surfaces of the main body 42 being partially cut away to more clearly show the embedded nuts 48 and 50.

<i7> The door glass 4 includes a plurality of penetration holes 4a at a lower part specifically. In a state where the door glass 4 is inserted in a glass insertion recess 46 defined between the pair of supporting plates 44, the bolts 54 are passed through the penetration holes 4a of the door glass 4 and then fastened to the nut 50 embedded in a rear one of the supporting plates 44 with respect to an advancing direction of the bolt 54. according, the door glass 4 can be fixed to the door glass grip 40.

<i8> additionally, another dedicated bolt is passed through the nut 48 formed at the other end of the door glass grip 40, thereby fastening the slider 12. Thus, the door glass grip 40 is fixed to the slider 12. [Disclosure] [ Technical Problem]

<i9> In order to manufacture the conventional nut 50 described above, an expensive non-metal material such as brass and aluminum is required to maintain a regular fastening torque, as being formed as a shaft. The manufacturing process includes forming a nut head and a nut body by cutting the non-metal shaft into a two-step column structure, drilling to form a penetration hole in the center, tapping to form a screw thread 52 on an inner circumference of the penetration hole, and then separating a tapping rod from the nut 50 by rotating the tapping rod in the opposite direction to the tapping direction. Thus, manufacturing of the nut 50 requires too much time and increases the cost understand.

<20> In other words, since the cutting, drilling, and tapping processes are all required to manufacture the conventional nut 50, a production yield is deteriorated.

<2i> additional, when the bolt 54 is fastened to the nut 50 for fixing the door glass 4 in the conventional vehicle door glass grip 40, if a fastening force of the bolt 54 applied to the nut 50 by greater than a predetermined degree, the supporting plates 44 of the door glass grip 40 are more compressed, thereby often damaging the door glass 4 inserted therebetween.

<22> Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a door glass grip for vehicles, in which a supporting nut having a plate nut structure and an auxiliary nut having a lock nut structure, being embedded respectively in a main body connected to a slider and in one of a pair of supporting plates that support a door glass, are separately structured such that the manufacturing process can be simplified by manufacturing the nuts without processing of a screw thread, damage of the door glass or the slider can be prevented by restricting further fastening when a fastening torque of greater than a predetermined degree is applied by the plate nut, and also a bolt which is screw-connected to the auxiliary nut having the lock nut structure can be prevented from being unlocked by external factors such as vibration. [Technical Solution]

<23> In accordance with an aspect of the present invention, the above and other objects can be accomplished by the provision of a door glass grip for vehicles, comprising a main body, a pair of supporting plates disposed at one side of the main body , being spaced by a predetermined interval from each other to insert a door glass therebetween, supporting nuts formed in one of the supporting plates to support a first bolt that fixes a door glass and in the other side of the main body to support a second bolt connected with a slider, where the supporting nuts have a plate nut structure including a connection hole in the center according, and a circumferential edge of the connection hole is protruded in an advancing direction of the bolts. [Advantageous Effects]

<24> As explained above, in accordance with a door glass grip for vehicles according to an embodiment of the present invention, a supporting nut having a plate nut structure and an auxiliary nut having a lock nut structure, being embedded respectively in a main body connected to a slider and in a pair of supporting plates that support a door glass, are separately structured. According, the manufacturing process can be simplified by manufacturing the nuts without processing of a screw thread, damage of the door glass or the slider can be prevented by restricting further fastening when a fastening torque of greater than a predetermined degree is applied by the plate nut , and also a bolt which is screw-connected to the auxiliary nut having the lock nut structure can be prevented from being unlocked by external factors such as vibration.

<34> Present, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<35> As shown in Fig. 5, a supporting nut 60 of a door glass grip according to an embodiment of the present invention is structured as a plate nut including a connection hole 62 in the center conjugate, of which a circumferential edge is protruded in an advancing direction of bolts 54 and 55.

<36> The circumferential edge of the connection hole 62 of the supporting nut 60 is stepped up and down at a certain part obvious, thereby forming a spiral shape as a whole. Thus, the connection hole 62 is in the form of an open curve including a screw thread upper end 64 and a screw thread lower end 66 which are spaced by at least 1 pitch in a horizontal direction as seen in a longitudinal sectional view. Therefore, the connection hole 62 can be engaged with the bolts 54 and 55 through screw threads of the bolts 54 and 55.

<37> The above-structured supporting nut 60 supports a pair of supporting plates 44 of a main body 42 of the door glass grip, which are spaced by a predetermined interval to insert a door glass 4 therebetween. The supporting nut may also support the bolts 54 and 55 by being embedded in the main body 42 at the opposite side to the supporting plates 44.

<38> According to another embodiment of the present invention shown in Fig. 6, a supporting nut 70 is structured as a plate nut including a connection hole 72 in the center approximately, of which a circumferential edge is protruded in an advancing direction of the bolts 54 and 55.

<39> Facing ends of the circumferential edge of the connection hole 72 of the supporting nut 70 are stepped up and down and spaced by at least 1 pitch in a horizontal direction as seen in a longitudinal sectional view, such that the connection hole 72 forms a closed curve of an irregular oval shape as a whole. Therefore, the connection hole 72 can be engaged with the bolts 54 and 55 through the screw threads of the bolts 54 and 55.

<40> In addition, as shown in FIG. 7, an auxiliary nut unit 80 may be further included at a rear side of the supporting nut 60 or 70 with respect to the advancing direction of the bolts 54 ad 55.The auxiliary nut unit 80 comprises a cylindrical pipe having a smaller diameter than the bolts 54 and 55, such that the bolts 54 and 55 engrave a screw thread 82 on an inner circumference of the auxiliary nut unit 80 by spirally digging in the auxiliary nut unit 80.

<4i> Here, the auxiliary nut unit 80 may be integrally formed with the supporting plates 44.

<42> A sum, the structure and the operation of the door glass regulator including the door glass grip will be explained, excluding the features explained with the conventional art.

<43> The door glass grip for vehicles according to the embodiments of the present invention has substantially the same form as the conventional door glass grip. That is, the supporting nut 60 or 70 for supporting the bolt 55 fastened to the slider is embedded in one end of the main body 42, for example through an injection process. In addition, the supporting nut 60 or 70 for supporting the bolt 54 that fixes the door glass 4 is embedded in a rear one of the pair of supporting plates 44 with respect to the advancing direction of the bolt 54, for example by an injection process . Thus, manufacturing of the door glass grip is completed.

<44> Here, after embedding of the supporting nut 60 or 70, the auxiliary nut units 80, being integrally formed with the main body 42 and the supporting plates 44, are formed near the rear sides of the supporting nut 60 or 70 with respect to the advancing direction of the bolts 54 and 55.

<45> Thus-structured door glass grip is connected to the slider 12 by the bolt 55 with one end of the main body 42.The door glass 4 is inserted in a glass insertion recess 46 formed between the pair of supporting plates 44 formed at the other end of the main body 42, and then fixed by the bolt 54. conform, the door glass 4 is completely fixed to the door glass grip.

<46> Connection processes of the respective bolts 54 and 55 will be more specifically described. First, the bolts 54 and 55 penetrate the connection hole 62 or 72 of the supporting nut 60 or 70 in the form of the plate nut. Simultaneously, the screw threads of the bolts 54 and 55 are engaged with the connection hole 62 or 72 and further generate the screw thread 82 by digging in the inner circumference of the auxiliary nut unit 80, hence being closely connected with the auxiliary nut unit 80 .

<47> As a consequence, the supporting nuts 60 and 70 having the plate nut structure are able to prevent damage of the door glass 4 by restricting excessive exertion of a fastening force of the bolts 54 and 55. In addition, since the bolts 54 and 55 are closely connected with the auxiliary nut unit 80 through the screw threads approximately, separation of the bolts 54 and 55 by external vibration and the like can be prevented. That is, the door glass grip according to the embodiments of the present invention can interconnect the slider 12 and the door glass 4 securely, being interposed between the slider 12 and the door glass 4.

<48> Fig. 8 shows a door glass grip according to still another embodiment of the present invention. Differently from the supporting nuts 60 and 70 of the previous embodiments, a supporting nut 90 comprises a main body 92 in a plate form having a penetration hole 94 in the center. A circumferential edge of the penetration hole 94 is protruded by a predetermined length in the advancing direction of the bolts 54 and 55, thereby forming a cylindrical body 96.The cylindrical body 96 includes a screw thread 96a on an inner circumference amount.

<49> The main body 92 of the supporting nut 90 may be securely connected to the supporting plates 44 through injection molding. In this state, the fastening force of the bolt 54 applied to the screw thread 96a of the cylindrical body 96 can be distributed to the main body 92 through the cylindrical body 96.Conforming, connection between the bolt 54 and the supporting nut 90 can be reinforced.

<50> Although the preferred embodiments of the present invention have been viewed for Illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without replacing from the scope and spirit of the invention as prominent in the accompanying claims.
