The invention according to claim 1 comprises a pair of left and right rails extending in the vertical direction and constituting a front portion of the vehicle body, and a lower window plate supported by the vehicle body so as to close a lower portion of a window opening formed between the left and right rails. And an upper window plate that is provided so as to close the upper portion of the window opening, and travels downward so as to overlap the lower window plate and is supported by the left and right rails so as to be movable backward. In the windscreen at
A reinforcing material attached to the upper edge of the lower window plate and a seal material for sealing between the upper edge of the lower window plate and the upper window plate are provided.

  Therefore, the reinforcing material prevents the upper edge of the lower window plate from being bent when the vehicle is traveling or when the upper window plate is moved forward and backward when opening and closing the window opening of the front window. The Further, since the lower edge portion of the upper window plate is reinforced by the reinforcing material via the sealing material, the lower edge portion of the upper window plate is also prevented from being bent.

  Therefore, it is prevented that the lower window plate and the upper window plate are repeatedly bent to generate noise when the vehicle is running. This is particularly beneficial for golf carts that are generally installed in a golf course that is a quiet environment.

  In addition, as described above, since the sealing material for sealing between the upper edge portion of the lower window plate and the upper window plate is provided, the vehicle interior inside the vehicle body passes through the gap between the lower window plate and the upper window plate. It is prevented by the sealing material that an external wind and rain or dust enters the door. Therefore, riding comfort to the vehicle is improved.

According to a second aspect of the present invention, there is provided a front wind in a small vehicle including a seat disposed behind the front wind and supported by the vehicle body.
The reinforcing material and the sealing material are positioned lower than the position of the eyes of the seated person seated on the seat.

  For this reason, when the seated person on the seat looks forward through the front window, the reinforcing material and the sealing material are prevented from obstructing the field of view. Therefore, even when the reinforcing material and the sealing material are provided, the riding comfort of the vehicle can be kept good.

According to a third aspect of the present invention, there is provided a pair of left and right rails extending in the vertical direction and constituting a front portion of a vehicle body, and a lower window plate supported by the vehicle body so as to close a lower portion of a window opening formed between the left and right rails. And an upper window plate that is provided so as to close the upper portion of the window opening, and travels downward so as to overlap the lower window plate and is supported by the left and right rails so as to be movable backward. In the windscreen at
The upper window plate is made of an elastic material, and is supported by the left and right rails in a state where the upper window plate is elastically bent.

  For this reason, the upper window plate attempts to return to its original shape by its own elastic force. The upper window plate is pressed against the rail side by the elastic force. Therefore, the upper window plate is prevented from rattling with respect to the rail side, and the generation of noise during traveling of the vehicle is prevented.

  According to a fourth aspect of the present invention, there is provided a movable body that can move forward and backward along the rails, and the movable body includes upper, lower ends, and intermediate portions on the side edges of the upper window plate. It is made to support on each said rail via.

  For this reason, when the upper window plate moves forward and backward with respect to the rails, the upper window plate is prevented from directly sliding with respect to the rails. Therefore, the durability of the upper window plate is improved, and the upper window plate can be moved back and forth more smoothly by selecting the moving body having a small friction coefficient.

  According to a fifth aspect of the present invention, there is provided a fully closed state in which the upper window plate fully closes the upper portion of the window opening, and a fully open state in which the upper window plate moves forward and the upper portion of the window opening is fully opened. Among these, there is provided a pressure contact body that presses each side edge portion of the upper window plate to the rail side in at least one of the states.

  Here, the vehicle often travels in the fully closed state or the fully open state. In this case, since the upper window plate is in pressure contact with the rail side as described above, the upper window plate is prevented from rattling against the rail side, and the generation of noise during traveling of the vehicle is prevented. .

According to a sixth aspect of the present invention, there is provided a front wind in a small vehicle including a roof plate that constitutes an upper surface portion of the vehicle body and whose front edge portion covers the upper edge portion of the fully closed upper window plate from the front side. ,
In the fully closed state, the press contact body is in pressure contact with the rear surface of the upper end portion of the side edge of the upper window plate.

  For this reason, in the fully closed state, the upper end portion of the side edge portion of the upper window plate is pushed forward by the pressure contact body and is brought close to the front edge portion of the roof plate. Then, the clearance gap between the upper edge part of the said upper window board and the front edge part of a roof board is narrowed. Accordingly, it is possible to prevent external wind and rain and dust from entering the passenger compartment inside the vehicle body through the gap. As a result, riding comfort on the vehicle is improved.

The invention according to claim 7 comprises a pair of left and right rails that constitute a front portion of the vehicle body and extend in the vertical direction, and a lower window plate supported by the vehicle body so as to close a lower portion of a window opening formed between the left and right rails.

In the state, another press contact body is provided that presses the middle portion in the width direction of the upper window plate against the vehicle body side.

  Here, the middle portion of the upper window plate in the width direction is a portion that is easily bent forward and backward when the vehicle travels. However, as described above, in the fully closed state or the fully open state, the middle portion of the upper window plate is pressed against the vehicle body side by the other pressing body. For this reason, the middle part of the upper window plate is prevented from rattling with respect to the vehicle body side, and the generation of noise during traveling of the vehicle is prevented.

According to an eighth aspect of the present invention, there is provided a front window for a small vehicle including a roof plate that constitutes an upper surface portion of the vehicle body and whose front edge portion covers the upper edge portion of the fully closed upper window plate from the front side. ,
In the fully closed state, the other press contact body is in pressure contact with the rear surface of the upper edge of the upper window plate.

  For this reason, when in the fully closed state, the middle part of the upper edge of the upper window plate is elastically bent forward by the other press-contacting body and brought closer to the front edge of the roof plate. Then, the clearance gap between the upper edge part of the said upper window board and the front edge part of a roof board is narrowed. Accordingly, it is possible to prevent external wind and rain and dust from entering the passenger compartment inside the vehicle body through the gap. As a result, riding comfort on the vehicle is improved.

  According to a ninth aspect of the present invention, each of the rails is used as a skeleton member of a vehicle body, and each of the rails is formed of an extruded material.

  For this reason, since the rails are used for the front frame which is a skeleton member of the vehicle body, the number of components of the vehicle body is reduced, and the configuration of the vehicle is simplified.

  Further, since each of the rails is formed by an extrusion material that can be easily molded, the vehicle can be molded accordingly.

  According to a tenth aspect of the present invention, the front edge portion of each rail protrudes forward from the side edge portions of the lower window plate and the upper window plate.

  Here, when the wind and rain collide with the front of the lower window plate and the upper window plate, such as when the vehicle is running, a part of the wind and rain bypasses each side edge of the lower window plate and the upper window plate. And try to enter the cabin inside the car body. However, it is prevented by the front edge part of each rail which protruded as mentioned above that a part of wind and rain tries to bypass each side edge part side of a lower window board and an upper window board in this way. Therefore, intrusion of wind and rain into the vehicle compartment is more reliably prevented, and the riding comfort of the vehicle is further improved.

  According to the eleventh aspect of the present invention, a handle is attached to the lower edge portion of the upper window plate.

  For this reason, even a person with a short height can easily move the upper window plate back and forth by gripping the handle.

  Further, when the seated person on the seat looks forward through the front window, the handle is prevented from obstructing the field of view. Therefore, even when the handle is provided, the ride comfort on the vehicle is kept good.

According to a twelfth aspect of the present invention, there is provided a windshield for a small vehicle including a pair of left and right side frames that constitute an upper portion of a vehicle body and extend in a longitudinal direction of the vehicle.

Therefore, the durability of the upper window plate 29 is improved, and the upper window plate 29 can be moved forward and backward A and B more smoothly by selecting the moving bodies 37-39 having a small friction coefficient. .

  In addition, as described above, the upper window plate 29 makes the upper part of the window opening 27 fully closed, and the upper window plate 29 moves forward A so that the upper part of the window opening 27 is fully opened. Pressure contacts 49, 50, and 54 are provided for pressing each side edge of the upper window plate 29 to the rail 26 side in at least one of the “fully open states”.

  Here, the vehicle 1 often travels in the “fully closed state” or “fully opened state”. In this case, since the upper window plate 29 is in pressure contact with the rail 26 side as described above, the upper window plate 29 is prevented from rattling with respect to the rail 26 side, and noise during the traveling of the vehicle 1 is prevented. Occurrence is prevented.

  Further, as described above, when in the “fully closed state”, the pressure contact body 49 is in pressure contact with the rear surface of the upper end portion of the side edge of the upper window plate 29.

  Therefore, in the “fully closed state”, the upper end portion of the side edge portion of the upper window plate 29 is pushed forward by the pressure contact body 49 so as to approach the front edge portion 48 of the roof plate 22. . Then, the clearance gap between the upper edge part of the said upper window board 29 and the front edge part 48 of the roof board 22 is narrowed. Thus, it is possible to prevent external wind and rain and dust from entering the vehicle compartment 5 inside the vehicle body 2 through this gap. As a result, the riding comfort on the vehicle 1 is improved.

  In addition, as described above, the upper window plate 29 makes the upper part of the window opening 27 fully closed, and the upper window plate 29 moves forward A so that the upper part of the window opening 27 is fully opened. The other press-contact bodies 52 and 55 that press the intermediate part in the width direction of the upper window plate 29 to the vehicle body 2 side in at least one of the “fully open states” are provided.

  Here, the middle portion in the width direction of the upper window plate 29 is a portion that is easily bent forward and backward when the vehicle 1 is traveling. However, as described above, in the “fully closed state” or “fully opened state”, the middle portion of the upper window plate 29 is pressed against the vehicle body 2 by the other pressing members 52 and 55. For this reason, the middle portion of the upper window plate 29 is prevented from rattling with respect to the vehicle body 2 side, and the generation of noise during the traveling of the vehicle 1 is prevented.

  Further, as described above, in the “fully closed state”, the other press contact body 52 is in pressure contact with the rear surface of the upper edge portion of the upper window plate 29.

  Therefore, in the “fully closed state”, the middle portion of the upper edge portion of the upper window plate 29 is elastically bent forward by the other press contact body 52, so that the front edge portion of the roof plate 22 is 48. Then, the clearance gap between the upper edge part of the said upper window board 29 and the front edge part 48 of the roof board 22 is narrowed. Accordingly, it is possible to prevent external wind and rain and dust from entering the vehicle compartment 5 inside the vehicle body 2 through this gap. As a result, the riding comfort on the vehicle 1 is improved.

  In the above case, the upper window plate 29 is moved to the vehicle body 2 side and the rail 26 side only in the “fully closed state” and “fully opened state” within the range in which the upper window plate 29 moves forward and backwards A and B. The pressure contact bodies 49, 50, 52, 54, and 55 are in pressure contact.

  For this reason, when the upper window plate 29 goes back and forth between the “fully closed state” and the “fully opened state” and moves backwards A and B, it is released from the pressure contact. Therefore, the forward and backward movements A and B of the upper window plate 29 can be smoothly performed.

  Further, as described above, each rail 26 is used as a skeleton member of the vehicle body 2, and each rail 26 is formed of an extruded material.

  Moreover, since each said rail 26 is shape | molded by the extrusion material which is easy to shape | mold, the shaping | molding of the said vehicle 1 becomes easy to that extent.

  Further, as described above, the front edge portion 41 of each rail 26 protrudes forward from the side edge portions of the lower window plate 28 and the upper window plate 29.

  Here, when the wind and rain collide with the front surfaces of the lower window plate 28 and the upper window plate 29, such as when the vehicle 1 is traveling, a part of the wind and rain is caused by each of the lower window plate 28 and the upper window plate 29. It tries to enter the compartment 5 inside the vehicle body 2 by bypassing the side edge. However, it is prevented by the front edge portion 41 of each rail 26 protruding as described above that a part of the wind and rain tries to bypass the side edge portions of the lower window plate 28 and the upper window plate 29 in this way. The Therefore, intrusion of wind and rain into the vehicle compartment 5 is more reliably prevented, and the riding comfort on the vehicle 1 is further improved.

  As described above, the handle 60 is attached to the lower edge of the upper window plate 29.

  For this reason, even a person with a short height can easily move the upper window plate 29 forward and backward, A and B by gripping the handle 60.

  Further, when the seated person 9 on the seat 7 looks forward through the front window 23, the handle 60 is prevented from obstructing the field of view. Therefore, even if the handle 60 is provided, the ride comfort on the vehicle 1 is kept good.

  Further, as described above, the front end portion of each side frame 18 is fitted and fixed to the upper end portion of each rail 26.

  For this reason, when the vehicle 1 is assembled, the front end portions of the side frames 18 are fitted to the upper end portions of the rails 26, whereby the positioning and temporary assembly of both the members 26 and 26 are facilitated. Therefore, the assembly work of the vehicle 1 can be facilitated accordingly.

  Further, since the side frame 18 and the rail 26 are fixed in a state of being fitted to each other, the coupling strength between the two frames 18 and 26 is improved, and the strength and rigidity of the vehicle body 2 are improved.
