In this case, the window pressing portion 10 may be configured to include the suction member 11 and the pressing member 12. In addition, the window pressing portion 10 may be constituted by a plurality of windows to pressurize the window glass 2 in a dispersed manner.

The suction member (11) is a member which is in contact with the side window (2) of the railway car (1). The pressing force by the pressing member 12 can be transmitted to the windshield 2 without the slippage due to the weight or the surface characteristics of the windshield 2 compared with the case of using a member having a hardness lower than that of the glass simply by using the suction member 10 have.

The pressure member (12) presses the adsorption member (11). To this end, the pressing member 12 is provided so as to be movable toward the windshield 2 with respect to the support bar 20 to be described later. Needless to say, the pressure member 12 may be directly connected to one side of the adsorption member 11.

At this time, the pressing member 12 may be provided so as to press the suction member 11 in a direction perpendicular to the side window glass 2 of the railway car 1. It is possible to effectively pressurize the adsorption member 11 without slipping due to the weight or surface characteristics of the glass window 10 by pressing the adsorption member 11 in the direction perpendicular to the glass window 2. [

Further, the pressing member 12 may be provided so as to be movable in a screw manner while being pivoted through the support bar 20. That is, the pressing member 12 may be provided with a threaded portion 12a on the outer circumferential surface in the longitudinal direction thereof, and penetrate the through hole 21 of the supporting bar 20 in a screw manner.

In this case, the damper member (not shown) may be installed on one side of the suction member 12 because the suction member 11 may be twisted or deformed when the suction member 11 receives the rotational force when the pressing member 12 is moved by rotation of the shaft So that the rotational force can be buffered.

On the other hand, the window pressing portion 10 may further include a handle 13 for rotating the pressing member 12. The handle 13 allows the pressing member 12 to be easily moved through the self-supporting bar 20 using the side window fixing device of the railway car according to the present invention for fixing the windshield 2.

The support bar 20 is fixed so as to be spaced apart from the vehicle body of the railway car 1 to support the window presser portion 10. That is, the support bar 20 supports the window presser portion 10 to move toward the window pane 2 with respect to the support bar 20 so as to press the window pane 2.

At this time, the supporting bar 20 may be provided with a through hole 21 through which at least one window pressing part 10 passes. That is, the pressing member 12 of the window pressing portion 10 is guided by the through-hole 21 so as to be movable without flowing.

It is obvious that a plurality of through holes 21 should be formed at intervals smaller than the height of the windshield 2 in view of the purpose of fixing and supporting the windshield 2 of the present invention.

In this case, it is preferable that a through-hole 21 is formed with a nut portion, though not shown, to which the threaded portion 12a of the pressing member 12 is guided.

On both ends of the supporting bar 20, a first male threaded portion 22 to be coupled with a rock forming portion 40 to be described later can be extended.

A pair of bar fixing portions (30) fix the support bar (20) so as to be spaced apart from the vehicle body of the railway car (1). That is, the pair of bar fixing portions 30 are provided on the upper and lower portions of the vehicle body, respectively, and are connected to both ends of the support bar 20 positioned therebetween to fix and support the support bar 20.

In this case, the bar 30 is directly or indirectly connected to both ends of the support bar 20 to generate tension in a state of being tensed together with the support bar 20. The indirect connection is a case where the rock rough part 40 to be described later is interposed.

The raising and lowering unit 30 is preferably installed on upper and lower parts of the vehicle body of the railway car 1 so as to more easily mount and disassemble the side window fixing device of the railway vehicle according to the present invention.

For example, as shown in FIG. 2, the bar fixing part 30 may be formed by bending an end thereof. That is, the end portion of the bar fixing portion 30 is composed of the first bent portion 31 and the second bent portion 32 extending from the first bent portion 31, so that the bar fixing portion 30 can be installed so as to hang on the vehicle body.

On the other hand, a second male threaded portion 33, which is to be coupled with a later-described rocky stone forming portion 40, may be formed at the other end of the fastening portion 30.

In this case, when the apparatus according to the present invention is installed on the vehicle body, the second male threaded portion 33 and the support bar 20 formed in the pair of bar fixing portions 30 are arranged in a straight line As shown in FIG.

It is preferable that the second male screw portion 33 is formed by forming a screw thread in the direction opposite to the first male screw portion 22 in order to implement the function of the turnbuckle of the rock roughness portion 40.

Meanwhile, the side window fixing device of the railway vehicle according to the embodiment of the present invention may further include a rock crest portion 40.

The rock rough part 40 is provided between the support bar 20 and the bar fixing part 30 so as to adjust the position of the support bar 20 between the pair of bar support parts 30, .

In this case, the rock rough part 40 can adjust the position of the support bar 20 in a turnbuckle manner. That is, the rock rough part 40 may include a body part 43 and female screw parts 41 and 42 and may operate in a turnbuckle manner.

The first female screw portion 41 guides the first male screw portion 22 to rotate linearly and linearly moves while the second female screw portion 42 guides the second male screw portion 33 to the first male screw portion 22, So as to linearly move in the opposite direction.

The body portion 43 applies a rotational force to the female threaded portions 41 and 42 to linearly move the male threaded portions 22 and 33. In this case, the body portion 43 may be provided with a receiving space 44 for receiving the first male screw portion 22 and the second male screw portion 33. Specifically, when the distance between the support bar 20 and the bar 30 is shortened, the male threaded portions 22 and 23 Is accommodated in the accommodating space 44.

Accordingly, when the apparatus according to the present invention is installed on the body of the railway car 1, the barge 30, the rocker unit 40, and the support bar 20 are connected to each other to generate tension, The position of the support bar 20 is adjusted through the guide 40. [ Therefore, the position at which the window pressing portion 10 presses the window 2 can be set by adjusting the position of the supporting bar 20, so that the positional precision of the window 2 is improved.

It is also possible to adjust the magnitude of the tension created by the connection of the hopper 30, the rock rough section 40, and the support bar 20 by the rock rough section 40. In this case, the tension can also be adjusted by changing the pressing force by the window pressing portion 10.

Hereinafter, with reference to Figs. 1 and 6, the schematic mechanical relationship of the side window fixing device of the railway vehicle according to the present invention will be described together with its operation.

The rocker unit 40 and the support bar 20 are connected to each other on the side surface of the railway car 1 and the window presser 10 is connected to the support bar 20 So that the glass window 2 is pressed and supported.

In this case, letting the pair of bucking portions 30 form the angle of inclination? 1 and? 2 with the extension line of the support bar 20 and the rock roughness portion 40, 40 are referred to as T1 and T2, respectively.

It is also assumed that the window pressing portion 10 penetrates through the supporting bar 20 and the pressing force of the glass window 2 whose mass m is vertical is F1 and F2 respectively so that the body of the railway car 1 corresponds to the pressing force, ) Are called N1 and N2, respectively. In addition, the friction coefficient between the vehicle body and the windshield 2 is μ, and the acceleration of gravity is g.

In this case, in consideration of the equilibrium of the force in the horizontal direction,

T1sin? 1 + T2sin? 2 = F1 + F2 = N1 + N2

.

Also, considering the equilibrium of force in the vertical direction,

T1cos? 1 + mg = T2cos? 2 + (N1 + N2)?

.

In this case, assuming an ideal case, the equilibrium of force is given by θ1 = θ2 = θ, the tension T1 = T2 = T, and the vertical drag N1 = N2 = N.

T sin? = F = N,

mg = 2Nμ

Therefore, a value of T = mg / mu 2 sin [theta] is derived.

Therefore, when the magnitude of the tensile force is mg / mu 2 sin &thetas;, the windshield 2 does not fall on the base of the railway car body 1 due to its own weight.

In order to achieve the above-described equilibrium of force, the side window fixing device of the railway vehicle according to the present invention comprises a bar fixing part 30, a rock forming part 40 and a supporting bar 20 connected to each other, Passes through the support bar 20 and presses the glass window 2 to generate tension.

In addition, by adjusting the rock roughness part 40 and the window pressing part 10 to such an extent that no sagging of the windshield 2 occurs with the naked eye, an approximate tension is formed at T = mg / mu 2 sin ?. In this case, as shown in FIG. 1, it is needless to say that a plurality of the devices according to the present invention can be used to fix the windshield 2 in order to more easily obtain an approximate tension to the equilibrium of the force through dispersion of the force .

As described above, the side window fixing device for a railway vehicle according to the present invention can be installed and disassembled more easily by reducing the weight, effectively preventing the base portion of the windshield and the vehicle body from being closely attached due to the weight of the windshield itself, The position can be adjusted to improve the position accuracy of the windshield.

As described above, the present invention has been described with reference to the embodiments shown in the drawings. However, it should be understood that the present invention is not limited to the above-described embodiments, and various modifications and other equivalent embodiments may be made on the basis of common knowledge in the art. .
