Abstract

PURPOSE:To prevent tractor operator's clothing from being caught by a striker when the operator gets in or out of the tractor and thereby enhance safety by installing a hand catcher, which is convenient for the operator to get in and out of the tractor, in such a manner that the catcher encircles the projected part of the striker. CONSTITUTION:A door 4 of a tractor is installed on a front frame 5 of a cabin by means of a hinge 8. A door lock part consists of a latch 10, which is provided at the rear part of the door 4, and a striker 13. In addition, an inside handle 14 and an outside handle 15, both of which are used for opening/closing operation of the door are installed inside and outside the door 4, respectively. A hand catcher 16, which is a hand grip for an operator to get in or out of the tractor, is installed on a frame 11 at the side part of the cabin in such a manner that the catcher 16 encircles the upper part of the striker 13. Since the striker 13 is guarded by the catcher 16 like this, no situation occurs in which a part of the body or clothing of the operator is caught by a projection 23 by mistake while he is getting in or out of the tractor.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention applies to the structure of a door lock part in a tractor cabin or the like.

The door that is removed from the tractor cabin is
Although it is configured to be locked by engagement of a latch and a striker, clothes were often caught on the striker or J4 l4 It'f provided on the fly J side of the cabin.

This invention provides a lock that is exposed to the cabin population, lL
This prevents accidents such as clothes getting caught in the cabin.
It was designed to make f1 descent safe and easy, and is characterized by having a hand catcher for getting on and off the vehicle mounted on the frame so as to surround the striker installation part. The embodiments shown in the drawings will be described below.

Fig. 1 is an external view of a tractor equipped with a door lock structure according to the present invention, and Fig. 2 is a door lock 8 seen from inside.
3 external view, 3rd IN is a sectional view of the door lock part, 4th IN is a sectional view of the door lock part,
These figures and FIG. 5 are an enlarged front view and side view of the main parts. The cabin 2 of the truck 1 is provided with doors 4 on the left and right inner sides. The door 4 is secured to the front frame 5 of the cabin 2 by means of a hinge 7.8;
It can be opened and closed by rotating it in and out around 8. The door lock part consists of a launch 10 provided at the rear of the door 4 and a striker 13 located at a corresponding position on the side frame II of the cabin 2, and an inside handle for opening and closing the door inside and outside the door 4. 148 side handle 15 is provided. In addition, the frame 11 is provided with a hand cancher 1 for getting on and off, surrounding the L part of the striker 13.
The tip 10a of the latch 10 that is not removed is slanted! , lJ is a square bar-shaped member which is fixed to the inner surface of the inner panel 17 of the door 4, and is biased in the protruding direction by a spring, and is attached to the inner panel 17 with +tiJ The opening 11 is exposed to the indoor side through the opening 20. The striker 13 has an engagement hole 22 in the center thereof that is slightly wider than the width of the tip of the tip 10, and has a flat protrusion 23 with an oblique tip 23a. When the door 4 is further closed from the position shown in FIG.
enters, and the tip 23a touches the tip 10a of the launch 10.
23a and ioa move along their respective inclined surfaces, and are once pushed into the latch 10 or holder 18, and then inserted into the engagement hole 22 of the protrusion 23. The length of the door is made by the inside handle 14 or the outside/bend 3.
5, the launch 10 is drawn into the holder 18 and disengaged from the striker 13, allowing the door 4 to be opened.

The hand catcher 1B consists of a grip section 25 and two wooden supports 28 on the left and right sides. It is formed into a roughly portal shape consisting of '28, and supports)
] 26 is a mounting portion provided with a screw hole. This hand catch'+16 has a post of 26°26
are located on both sides of the striker 13, and are fixed to the side frame 11 by screws 27 inserted into screw holes in the tip end portion 28a of the column so as to surround the striker 13. As a result, the grip portion 25 serves to cover the striker 13, thereby preventing the body or clothing from being accidentally caught on the protrusion 23 when getting on and off the vehicle. Since the height from the ground to the seat of a tractor is higher than that of a passenger car, etc., it is necessary to use hand tools or other aids for getting on and off the vehicle. It's convenient. Note that the hand catcher 16 in the illustrated example is inclined toward the indoor side by an angle O, and the gap between it and the door is large. Accidents such as being caught between the hand catcher and the hand catcher can be effectively prevented.

The latch and striker are not limited to the illustrated example, and there are various shapes, but in any case, a hand catcher may be provided to cover the protruding portion of the striker. If the striker is installed on the door side, and the catch is sunk into the cabin frame, the hunt catcher can be sunk so as to surround the latch.

As is clear from the above description, in the present invention, the hand catcher for getting on and off is provided so as to surround the protrusion of the striker, making it convenient for going up and down. It is now highly safe.
