[Structure] A seat 2 is rotatably supported in the longitudinal direction on a support base 1, and the rear end of the seat 2 and the lower end of a seat back 3 are hingedly connected. A seat back 3 and a support base 1 are connected by freely expandable and contractible members 8 and 9 provided with a lock mechanism 20.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an improvement of a chair for a driver's seat or the like of a small boat.

0002

[Conventional technology]

As a chair for the driver's seat of a small boat, a damper is inserted between the seat and the hull. It is well known that this technology absorbs the motion and vibration of the ship and provides a comfortable ride. It is being

0003

[Problems to be devised]

However, when operating the car while standing up, such as during rough weather or when there are large waves, In such cases, a chair designed in this way may be of no use and may actually become a hindrance. was there.

0004 This invention was made to solve the above problems. A chair that doubles as a backrest and can also support your body while standing up. The purpose is to provide children.

[0005]

[Means to achieve the task]

The present invention supports a seat freely rotatably in the front and rear directions on a support base supported on the floor. The rear edge of the seat and the lower edge of the seat back are hinged together, and the seat back and a support base are connected by a freely expandable and contractible member equipped with a locking mechanism.

[0006]

[Effect]

When the locking mechanism is released, the seat along with the seatback will respond to the applied operating force. As a result, the telescopic member is rotated and displaced while expanding and contracting. Locking mechanism in a predetermined rotational position If you lock the expansion and contraction of the elastic member, the seat and seat back will be supported at that angle. .

[0007]

【Example】

An embodiment of the present invention is shown in FIGS. 1 and 2.

[0008] In FIG. 1, 1 is supported on the floor of a ship via a retractable seat damper 10. It is a support stand. A pin 4 is provided on the support base 1 to protrude laterally, and a pin 4 is provided in the middle of the seat 3. is supported by this pin 4 so as to be freely rotatable in the front-rear direction.

[0009] The rear end of the seat 3 is located under the hollow slide member 9 fixed to the back of the seat back 2. It is connected to the end via a hinge 5.

0010 Further, a guide tube 8 connected to the support base 1 via a hinge 7 is a sliding member. It freely slides through the hollow part of 9. What is this guide tube 8 and slide member 9? It functions as a member that connects the support base 1 and the seat back 2 in a freely expandable and contractable manner.

[0011] The slide member 9 is provided with a locking mechanism 20 as shown in FIG. lock machine The structure 20 includes a lock pin 1 inserted into a holder 18 formed on the slide member 9. 4, a spring 15 that urges it toward the guide tube 8, and a holder 18. It consists of a handle 16 fixed to the base end of a lock pin 14 that protrudes outward from the lock. The tips of the pins 14 form lock holes at the top and bottom of the guide tube 8, respectively. 17 to prevent the slide member 9 from sliding with respect to the guide tube 8. lock.

0012 Next, the effect will be explained.

[0013] When using the chair as a regular chair, insert the lock pin 14 into the lower part of the guide tube 8. into the lock hole 17 of the slide member 9, and insert the slide member 9 into the guide chute as shown by the solid line in FIG. It is locked at the bottom of the tube 8.

[0014] In this state, the seat 3 is supported approximately horizontally on the support base 1, and the seat back 2 is It is supported in a backward tilted state by the slide member 9 whose slide is locked.

[0015] On the other hand, when you stand up and operate the vehicle, the handle 16 of the locking mechanism 20 Pull to unlock the slide member 9 and lift the seat back 2. this As a result, the seat 3 connected to the seat back 2 via the hinge 5 pivots around the pin 4 as a fulcrum. As it rotates, the slide member 9 slides upward along the guide tube 8.

[0016] When the seat 3 and seat back 2 are displaced to the position shown by the chain line in the figure, turn the handle 1 6, the lock pin 14 biased by the spring 15 will lock into the guide tube 8. The slide member 9 enters the lock hole 17 formed in the upper part, and the slide member 9 is inserted into the upper part of the guide tube 8. It is locked in the section. As a result, the seat 3 and the seat back 2 are placed at the position indicated by the chain line in the figure. Supported by

[0017] Therefore, when standing up to drive in stormy weather, seat 3 and seat bar By setting rack 2 in this way, you can get a backrest and reduce the fatigue associated with driving. Labor is reduced. Also, the chair does not get in the way of driving.

[0018] Note that if a large number of lock holes 17 are formed in the guide tube 8, the seat 3 and the seat The back 2 can be supported at any angle other than the above.

[0019]

[Effect of the idea]

As described above, the present invention allows the seat to be freely rotatably supported in the front and rear directions on the support base. , the seat back hinged to the seat is a freely extendable member with a locking mechanism. Since I supported it on the support stand, I decided to release the locking mechanism and lift the seat back. This allows the seat and seat back to be supported in the upright position.

[0020] Therefore, if this invention is applied to the driver's seat of a small boat, it can be used as a normal driver's seat. In addition to its function, it can also be used as a backrest when standing up to drive, reducing driver fatigue. Favorable effects such as reduced labor can be obtained.
