The horizontal posture of It is attached a steering wheel that can be made into a downward vertical position.

[0003]

[Problems to be solved by the device]

 Due to the restrictions for mounting on a fire engine, the length and width of the body frame in the front-rear direction are each about 1 m, and the height of the upper end of the body frame from the ground is about 90 cm to 1 m. Take a forward horizontal posture at a height of about 80 cm above the ground. Since the steering wheel is in a downward horizontal position while it is installed in a fire engine, the length of the steering wheel is about 75 cm. To use this hose carrier on the ground, change the steering handle from the downward vertical position to the forward horizontal position, and press the key switch (power switch), accelerator grip, and brake lever on the T-shaped handle at the front end. The firefighters operate the control device such as the forward / reverse switch to move it to the desired place. However, since the control handle is only about 75 cm long, while operating the control device of the T-shaped handle part. The rotating driving front wheels hit the feet of the accompanying firefighters, and there is a risk that the firefighters may fall and get injured. You need to be careful to avoid hitting it, which is very tiring. Furthermore, since this hose carrier is used in an emergency, the handling of the steering handle becomes rough, and the conventional steering handle made of a single rod is loose at the attachment point to the body frame. There are many obstacles.

It is a vehicle body frame having a shelf type loading platform 13 that is folded up and stored. The rear end of the loading platform is closed by an openable rear lid 14, and the fire hose is stored and taken out with the rear lid open.

At the upper end of the front surface of the body frame, there is attached a steering handle 20 which can be in a forward horizontal posture and a downward vertical posture. This steering handle has a rear post 21 attached to the vehicle body frame, which can be in a forward horizontal posture and a downward vertical posture, and a nearly T-shaped handle portion 23 at the front end, in which an accelerator pedal is provided. The front post 22 is provided with a steering device 24 such as a lip 25 and a brake lever 26. At least the rear portion of the front post is a square pipe material 28, and the square pipe material 28 is provided at the front end portion of the rear post. A square tubular member 29 fitted to the inner circumference is provided, whereby the front post 22 can be expanded and contracted in the axial direction with respect to the rear post 21, and it is non-rotatably connected in a nested manner, and its extension position and contraction position are determined by a positioning device. It is regulated at 30. The forward / backward changeover switch (selector switch) 27 is provided on the upper front portion of the vehicle body frame 10.

The positioning device 30 is provided on the square pipe member 28 at the rear portion of the front post, and is provided with an extension stop 31 that comes into contact with the rear end of the square tube member 29 of the rear post when the front post is extended. Similarly, a shortening stopper 32 that abuts the front end of the rear post when the front post is shortened, two positioning holes 33 and 34 also provided in the front and rear of the square pipe member 28, and a rectangular shape to the square tubular member 29. The extension stopper 31 comes into contact with the rear end of the square tube member 29, and when the front post is extended, the tip thereof projects into the rear positioning hole 34, and the shortening stopper 32 is attached to the square tube member 29. It comprises a positioning rod 35 which abuts on the front end and whose tip projects into the front positioning hole 33 when the front post is shortened. The positioning rod 35 is slidably held in a guide tube 36 fixed at a right angle to the rectangular tube member 29, and is urged by a coil spring 37 so that its tip projects into the positioning holes 33 and 34.

In order to increase the attachment strength between the rear post 21 of the steering wheel and the vehicle body frame 10, the rear post 21 of the steering wheel 20 is fixed to the upper end of the front portion of the vehicle body frame 10 and has a pair of base portions 41 that project forwardly in a short distance. , 41 'and the rear end is pivotally attached to each base, so that it can be in a forward horizontal position or a downward vertical position, and the front end is directly or indirectly welded to both sides of the front minute post. A pair of main rods 42, 42 ', and a pair of slide pipes 43, 43 slidably provided outside the respective main rods and fitted in series to the rear portion of the main rod and the bases 41, 41'. ', A connecting grip 44 that connects the pair of slide pipes in an H shape, and a pair of attachments that fit outside the main rods and receive the front ends with the collars 49, 49' to press the slide pipes backward. Constructed with bias springs 45 and 45 ' To achieve. The base parts 41, 41 'are bearing pieces fixed to the upper end of the front part of the vehicle body frame 10 with the slits 46, 46' oriented vertically, and the rear ends of the main rods 42, 42 '. Vertical protrusions 47, 47 'protruding from the above are projected into the slits 46, 46', and horizontal pins 48, 48 'are skewed between the protrusions of each main rod and the bearing pieces, so that the main rod is directed forward. It is pivoted so that it can be placed in either a horizontal position or a downward vertical position.

In the illustrated embodiment, in order to allow the front post to extend and contract with respect to the rear post, the main post is indirectly indirectly attached to both sides of the square tube member 29 that nestably connects the square pipe material at the rear part of the front post. Although the front ends of the rods 42 and 42 'are welded, if the front posts cannot expand and contract, the front ends of the main rods 42 and 42' may be welded directly to both sides of the front posts.

When mounted on a fire engine, the square pipe material 28 of the front post is pushed into the square tube member until the shortening stopper 32 contacts the front end of the square tube member 29. When the stopper 32 comes into contact with the front end of the square tube member to bring the front post to the shortened position, the tip of the positioning rod 35 is pushed into the front positioning hole 33 of the square pipe member by the urging force of the coil spring 37, and the front post is moved. Hold in a shortened state. The connecting grips 44 are then pulled forward against the biasing springs 45, 45 'and the pair of slide pipes 43, 43' are advanced to expose the rear post bases 41, 41 '. As a result, the main rods 42, 42 'of the rear post and the front post 22 are integrally brought into a downward vertical posture. Since the total length of the steering handle when the front post is shortened is about 75 cm, the front end facing down the steering handle does not touch the floor of the hose carrier mounting part of the fire engine or the ground. In order to prevent the downward steering handle from swinging and hitting the body frame, a latch 15 is attached to the lower front part of the body frame, and the hook 16 provided on the square tube member is bited by the above latch to prevent steadying. . In this way, the hose carrier is installed in the fire engine.

In order to dismount the hose carrier from the fire engine in order to use the hose of the hose carrier for feeding and using the hose carrier in the field to extinguish the fire, operate the latch 15 and remove the hook 16. , The front post and the pair of main rods are united to raise the front horizontal posture. In the forward horizontal posture, the restoring force of the biasing springs 45, 45 'causes the pair of slide pipes 43, 43' to retract until they come into contact with the vehicle body frame, and cover the rear post bases 41, 41 '. , The steering wheel will be in the forward horizontal position and will not be able to return to the downward vertical position. Then, holding the gripping ball 38 of the positioning rod 35, the positioning rod is pulled against the bias of the coil spring 37, and the tip thereof is pulled out from the front positioning hole 33 of the square pipe member 28, and the extension stopper 31 is used as the rectangular tubular member. Pull the front post out until it abuts the rear end of 29 and place the steering handle 20 in the extended position. When the front post is in the extended position, the tip of the positioning rod 35, which is biased by the coil spring 37, automatically projects into the rear positioning hole 34 of the square pipe material, and holds the front post in the extended state. The length that the front post can extend may be about 30 cm.

In this way, when the steering handle is extended and the hose carrier is lowered from the fire engine, the fire engineer holds the handle part 23 with both hands and operates the control device 24 to drive the hose carrier together with the hose carrier. Move to position. Since the steering wheel is extended, the front wheels do not touch the foot of the accompanying firefighter. After extinguishing the fire, fold the hose and store it in the luggage carrier, and then mount it on the fire engine.Reverse the above operation, shorten the front handle, return the steering handle to the downward vertical posture, and use the latch to hook it. Bite.

[Effect of device]

 According to claim 1, the front post of the steering handle can be restricted to the extended position and the shortened position with respect to the rear post by the positioning device. Therefore, when installed in a fire engine, it should be in the shortened position so that the steering handlebars should not touch the floor or the ground of the vehicle even when the steering handle is vertically downward, and the aircraft should be lowered horizontally from the fire engine and directed horizontally to move to the fire scene. When set to the extended position. As a result, the front wheels can be prevented from touching the feet of a fire brigade member who accompanies the pilot while operating the control device of the steering wheel, and the fire brigade member can operate the control device while running safely.

Further, according to claim 2, when the front post is extended, the extension stopper comes into contact with the rear end of the rectangular tube member of the rear post to automatically regulate the extension position, and at the same time, the tip of the positioning rod is rearwardly moved. Plunge into the locating hole to secure the front post in the extended position. Conversely, when the front post is retracted, the shortening stopper contacts the front end of the square tube member of the rear post to automatically regulate the shortening position, and at the same time, the tip of the positioning rod projects into the front positioning hole. And secure the front post in the shortened position. Therefore, it is possible to perform the extension / shortening operation of the front post quickly and accurately, and in particular, the extension work that needs to be operated suddenly can be instantaneously performed.

According to the third aspect, the rear post is attached to the front upper end portion of the vehicle body frame by the pair of base portions and the main rod, so that the attaching strength is extremely high. Since the pair of slide pipes fitted outside the pair of main rods are connected in an H shape by the connecting grip, the pair of slide pipes can be integrally retracted by pulling with the connecting grip. , Workability is good.
