Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an armrest that also serves as a door handle.

(Prior Art) Some conventional armrests of this type allow the position of the armrest main body to be adjusted in the vertical direction depending on the physique and preference of the occupant. These conventional devices have a structure with play in the sliding part, and
The operating lever for adjusting the position of the armrest body is arranged so as to protrude inside the vehicle interior.

(Problems to be Solved by the Invention) For this reason, conventional armrests have had the problem that there is play in the armrest body.
In addition, part of the occupant's body may come into contact with the operating lever, or clothing may get caught on the operating lever, resulting in injury to the occupant, damage to clothing, or an inadvertent change in the position of the armrest body due to unlocking. There was a problem.

The present invention was developed in view of the above-mentioned problems, and its purpose is to provide an armrest with no looseness in the armrest body, which can prevent injuries to occupants and damage to clothing, and prevent accidental changes in the position of the armrest body. The goal is to provide something that does not exist.

(Means for Solving the Problems) The present invention solves the above problems by providing an armrest that also serves as a door handle. A fixed rail is provided, and a movable rail formed of a base wall, a side wall, and an outer flange is provided on the armrest main body side and is inserted through the fixed rail, and a roller is installed so that the peripheral surface is pressed between the base wall portions of both rails. and steel balls are arranged so that their spherical surfaces are in pressure contact with both the side walls and flanges of both rails, and the balls are engaged with and disengaged from lock holes carved at regular intervals in the side walls of the fixed rails. An operating lever having a locking pawl is rotatably provided on the armrest main body side such that the operating part of the operating lever is located on the back side of the handle part of the armrest and not including the upper part of the back side of the handle part. It is characterized by this.

(Function) In the armrest of the present invention, the rollers and steel balls eliminate play in the movable rail, so the armrest body moves smoothly without play.
In addition, since the operating part of the operating lever is located on the back side of the handle and not including the upper part of the back side of the handle, as long as the occupant takes normal movements, part of his or her body or clothing will not be exposed to the operating part of the operating lever. It doesn't hit.

(Example) Hereinafter, an example of the present invention will be described in detail using the drawings. In FIGS. 1 to 5, reference numeral 1 denotes a fixed rail fixed to a door panel (inner panel) 10 so as to extend in the vertical direction, and is formed from a base wall portion 1a, a side wall portion 1b, and an inner flange portion 1c. 2 is a movable rail that is inserted through the fixed rail 1, and is formed from a base wall portion 2a, a side wall portion 2b, and an outer flange portion 2c. A bolt 4 for attaching to 2 is provided protrudingly. After the armrest main body 3 is inserted through the bolt 4, it is fixed with a nut 5. At this time, a bush (not shown) or the like may be provided. 6 is the base wall portion 1a,
a roller 7 arranged so that its peripheral surface is in pressure contact with 2a;
is a steel ball arranged so that its spherical surface is in pressure contact with the side wall parts 1b, 2b and the flange parts 1c, 2c,
8 regulates the movement of the roller 6 with a central hole 8a,
This is a retainer that restricts the movement of the steel balls 7 at the side and holds the rollers 6 and the steel balls 7 in alignment. Although not shown, this retainer 8 engages with the movable rail 2 and moves together with the movable rail 2.

Reference numeral 11 denotes a support plate fixed to the movable rail 2 and having a pair of curled portions 11a on the sides, and a pin 12 rotatably supported at both ends by the curled portions 11a.
An operating lever 13 is fixed to the. One end of this operating lever 13 is an operating part 13a, and as shown in FIGS. It is located on the back side of the handle, not including the upper part. Also, the operating lever 13
The other end is a lock pawl 13b, which engages and disengages with lock holes 1e formed at regular intervals on one side wall 1b of the fixed rail 1. The operating lever 13 is constantly urged by a torsion spring 14 in a direction in which the lock pawl 13b fits into the lock hole 1e.

Although the above explanation was about a mechanism near one end of the armrest, a similar mechanism is provided at the other end. The mechanism at the other end may or may not be provided with a locking mechanism. FIG. 5 shows the interlocking mechanism when a locking mechanism is attached (corresponding parts of the mechanisms at both ends are given the same reference numerals). In this example,
The rotation of the operating lever 13 is taken out by a rotating arm 15 fixed to a pin 12 and transmitted to the rotating arm 15 of the other mechanism via a rod 16, thereby interlocking locking and unlocking.

Next, the operation of the above embodiment will be explained. First, when the lock claw 13b of the operating lever 13 is fitted into the lock hole 1e of the fixed rail 1, no matter whether force is applied to the armrest body 3 from above or below,
The armrest main body 3 does not move and remains in this position unless an adjustment operation is performed. On the other hand, to adjust the position, insert your hand into the back side of the handle part 3b and push the operating part 13a of the operating lever 13 toward the side opposite to the door. With this, the lock claw 13
b comes out of the lock hole 1e, and the movable rail 2 is unlocked. Therefore, if the armrest main body 3 is moved upward or downward in this state and the operator releases the operating lever 13 at the optimum position, the armrest main body 3 is locked in a stable engagement position close to the optimum position.

According to the above configuration, play between the fixed rail 1 and the movable rail 2 is removed by the rollers 6 and the steel balls 7, so that the play of the movable rail 2 and the play of the armrest body 3 are eliminated.
Also, even if you touch the handle part 3b when closing the door,
Since the operating lever 13 is located at the back, the fingertips do not come into contact with the operating portion 13a of the operating lever 13. Furthermore, since the operating portion 13a does not protrude inside the vehicle interior, the aforementioned injury to the occupants and damage to their clothes will not occur.

Note that the present invention is not limited to the above embodiments. For example, the handle portion 3b of the armrest body 3
The structure in which the back side penetrates vertically is shown,
The present invention can also be applied to a configuration in which the upper surface of the armrest main body 3 is formed with a shallow recess into which the fingertips can fit.
However, in this case, it is necessary to provide a hole in the lower surface of the armrest main body 3 through which the hand can reach the operating portion 13a.

(Effects of the invention) As explained above, according to the invention, the play between the rails is eliminated by the rollers and the steel balls, and the armrest body is free from looseness. In addition, it is possible to prevent injuries to passengers and damage to their clothes, and it is possible to realize an armrest that does not cause accidental changes in the position of the armrest body.
