Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door seal for a tractor, and an object thereof is to easily seal a door glass when constructing a cabin.

0002

BACKGROUND OF THE INVENTION A tractor vehicle body includes a ROPS frame, a roof, a cabin, etc. as upper structures that cover the surroundings of the driver's seat, but each of these components has an independent structure. The present invention allows superstructures of various types to be obtained easily and inexpensively.

0003

[Means for Solving the Problems] The present invention provides a gate-shaped lops frame 5 extending over the left and right fenders 4 at the rear of a vehicle body 15 having a step 2 of a control floor 1 and a fender 4 of a rear wheel 3. A roof 6 is provided at the upper end of the ROPSU frame 5, and a front frame 7 is removably provided between the roof 6 and the front end of the step 2.
, and around the door opening surrounded by the front frame 7, there are a ROPS frame seal receiver 10, a roof seal receiver 11, and a step, which are a series of seal receiving surfaces to which the door seal 9 provided on the outer peripheral edge of the door glass 8 comes into contact. Seal receiver 12
, a front frame seal receiver 13 , and a fender seal receiver 14 .

0004

[Operations and Effects of the Invention] When using a simple LOPUS specification, the LOPUS frame 5 is attached to the rear of the fender 4. When a roof is used, a roof 6 is attached to the upper end of the LOPUS frame 5 facing forward. When making it into a cabin specification, a front frame 7 is attached and a door glass 8 that can be opened and closed is attached. Thereby, a cabin can be constructed using the LOPUS frame 5, roof 6, etc.

[0005] In the case of this cabin specification, a step seal receiver 12, a step seal receiver 12, a Fender seal receiver 14, lope seal receiver 5, roof seal receiver 11
, front frame seal receiver 13, etc. are provided as a series of seal receiving surfaces, so when the door glass 8 is closed, the door seal 9 on the periphery of the door glass 8 can be brought into contact to improve airtightness. In addition to sharing the LOPs frame 5, roof 6, etc., the structure is simple and inexpensive.

[0006]

[Embodiment] A tractor body 15 has a front wheel 16 and a rear wheel 3 that are steered by a steering handle 18.
Power is transmitted by an engine 17 mounted in the front, creating a four-wheel drive configuration. 19 is a bonnet that covers the engine 17 section, 20 is a dashboard that extends to the upper instrument panel on the front side of the control floor 1, and 21 is a lift arm installed on the upper part of the mission case 22 at the rear of the vehicle body 15, which connects the work equipment to the rear. Go up and down. The control floor 1 has a step 2 at the front and left and right fenders 4 at the rear, and a control seat 23 is provided between the left and right fenders 4. or,
The rear of the control floor 1 is configured in a bucket shape extending over the left and right fenders 4, the rear frame 24, etc., and an operation plate 25 is provided above the left and right fenders 4.

Support legs 27 are provided on the brackets 26 attached to the axle housings on both the left and right sides of the transmission case 22 and extend across the upper fender 4, and the upper portions of the left and right support legs 27 are connected by a rear frame 24. These left and right support legs 27
A portal-shaped lops frame 5 can be attached over the top. This LOPUS frame 5 is formed by forming a pair of inner and outer sheet metal members into a hollow predetermined cross-sectional shape, joining both side edges, and protruding the joint part to an appropriate width to form a LOPUS frame receiver 10. This ROPSU frame receiver 10 is formed along a portion facing the door opening and a portion facing the rear window glass 28, and has a reinforced structure to increase rigidity.

[0008] The roof 6 is formed into a wide, inverted dish shape that covers from above the cockpit 23 to above the dashboard 20, and has roof supports 11 that protrude vertically downward along the portions facing the door openings at both left and right ends. establish. The front frame 7 has a notch formed in the center of the lower part so as to straddle the dashboard 20 from side to side, and has lower window portions 29 on both left and right sides and an upper window portion 30 spanning the entire width of the left and right sides. The windows 29 and 30 are bent at appropriate angles and installed as a single sheet of glass (FIG. 9). The front frame 7 is hollow, and front frame seal receivers 13 are formed at appropriate widths on both left and right sides facing the door opening. 42 is a side mirror,
43 is a wiper.

The step 2 has an outer end surface bent downward to form a step seal receiver 12. A removable grip 31 is attached to the upper side of the fender 4 (Fig. 5,
6), this grip 31 is attached at an appropriate interval on the outside of the operation plate 25, which is integrally attached to the control floor 1 side of the fender 4. A flasher 32 is attached to the rear of the grip 31. Further, a spacer 33 of an appropriate shape is provided between the rear end of the grip 31 and the rear of the operation plate 25. The rear end of the operation plate 25 forms a receiving part 34 on the joint surface with the LOPUS frame 5 so that there is no gap therebetween.

[0010] When installing the door glass 8 to make it a cabin specification, remove the grip 31 and spacer 33,
A fender seal receiver 14 made of rubber or synthetic resin is adhered to the top surface of the fender 4 using double-sided tape or adhesive (Fig. 7
, Figure 8). In this way, the ROPs frame 5, the roof 6, the front frame 7, the fender seal receiver 14, etc. are removable from the vehicle body 15, but in the form in which they are attached, the ROPs frame receiver 10, the roof seal receiver 11, the front frame seal receiver 13, the fender seal receiver 14, etc., together with the step seal receiver 12, constitute a series of seal receiving surfaces along the door glass 8 surface.

[0011] The door glass 8 is attached to the door frames 35 and 36.
and is attached to the LOPUS frame 5 by a hinge 44. The door frame 35 is made of square pipes, and the door frame 3 is made of round pipes above and below.
Both ends of 6 are connected to form a rigid body. Further, a support bar 37 made of sheet metal is connected between the lower end of the door frame 35 and the middle part of the front side of the door frame 36, and the door glass 8 is divided into an upper part and a lower part of the receiver bar 37. It is installed. The outer periphery of the door glass 8 facing the door frames 35, 36 is made to protrude outward from these frames 35, 36, and a door seal 9 is fitted and bonded to the outer periphery. To install the door glass 8, a boss seat 38 made of rubber or synthetic resin is fitted into a mounting hole formed in the glass, and a mounting screw inserted into the boss seat is used to attach the door frame 35, 36, It is attached to the receiving bar 37, etc., and has a gap between it and the door frames 35, 36, the receiving bar 37, etc., so that they do not come into direct contact with each other.

A door handle 39 is provided on the outside of the receiving bar 37.
, a door key 40 is provided, and a lock release lever 41 for releasing the door lock is provided inside. The flasher 32 is attached to the rear part of the receiving beam 37 in the cabin specification. In addition, in the cabin specification, the window glass 28 can be opened by rotating the window glass 28 rearward around the hinge at the upper end of the LOP frame 5.

In FIG. 10, there is a LOPUS specification A in which only the LOPUS frame 5 is attached, and a roof 6 is attached to the LOPUS frame 5.
It is possible to select and change the following configurations: roof specification B with the front frame 7 attached, weather cabin specification C with the front frame 7 further attached, or cabin specification D with the door further attached.
