Description

[Detailed Description of the Invention] This invention relates to an armrest for holding the tone arm of a record player fixedly when not playing.

The armrests currently installed on record players on the market are dedicated to the tone arm to which they are attached, so they are fixed to the cabinet in advance.

Therefore, when the tone arm is replaced, if the effective length or shape of the tone arm is different, the hole for armrest attachment must be re-drilled.

By the way, the material used for cabinets in recent years is stone.
Since many materials that are difficult to process, such as cast and acrylic, have been used, drilling the holes is extremely difficult and repositioning is troublesome.

In addition, there was a drawback in terms of functionality, such as the need to choose a location that was easy to control.

This invention was developed in view of the problem of slanting, and its purpose is to provide an armrest that can be freely displaced in all directions within a certain range.

Next, an embodiment of this invention will be explained with reference to the drawings.

Reference numeral 1 denotes a rest body adjustment bar having a long hole 1a drilled over almost the entire length and a hole 1b drilled at one end; 2 a support shaft fitted into the hole 1b and fixed with a screw 3; ,
Reference numeral 4 denotes a fixed sleeve into which the support shaft 2 is fitted, and a step portion 4a is formed approximately in the middle, and a screw 4b is formed on the outer periphery below the step portion 4a.

5 is a nut for fixing the fixing sleeve 4 to the panel 6, and the stepped portion 41 is positioned on the top surface of the panel 6, and the nut 5 is tightened.
is fixed by screwing and tightening into the screw 4b.

Reference numeral 7 designates an adjusting screw for fixing the support shaft 4 which is screwed into the fixing sleeve 4 in the axial direction, and by tightening this screw, the rest main body adjusting bar 1 can be fixed at a desired angle and height.

8 has a smaller diameter than approximately the middle, and the small diameter portion 8a is inserted into the elongated hole 1a of the rest main body adjustment bar 1 to be slidable.
A screw is formed on the outer periphery of a, and a rest stand fixing nut 9 is screwed into the screw.

Reference numeral 10 denotes a tone arm holder, and an arm holder 10a made of synthetic resin is formed at the upper end.

The vertically movable rod 10b of the tone arm holder 10 is inserted into the shaft hole of the rest stand 8, and the arm holder 10a is fixed by a fixing adjustment screw 11 screwed into the shaft hole of the rest stand 8. can be fixed at the desired angle and height.

Next, to explain the operation based on the above configuration, if you have changed the tone arm and the tone arm cannot be held by the holding part 10a, first loosen the adjustment screw 7 and tighten the support shaft 2. The rest main body adjustment bar 1 is adjusted to a desired angle and height by moving up and down and rotating, and the adjustment screw 7 is tightened and fixed.

Next, the rest stand fixing nut 9 is loosened, and the rest stand 8 is slid with respect to the rest main body adjustment bar 1 and fixed at a desired position.

Furthermore, the adjustment screw 11 is loosened, and the tone arm holder 8 is moved up and down and rotated to adjust the tone arm to be held accurately, and the adjustment screw 11 is tightened.

This makes it possible to maintain the tone arm well against changes in shape and effective length.

Note that in the above, the tone arm holder 10 does not have to be vertically movable with respect to the rest stand 8.

That is, this is because the rest main body adjustment bar 1 is vertically movable relative to the fixed sleeve 4.

As mentioned above, this idea allows the rest main body adjustment bar to be freely rotated and moved up and down relative to the fixed sleeve attached to the panel, the rest stand to be freely slidable relative to the rest main body adjustment bar, and the tone arm holder. By making it rotatable relative to the rest stand, the tone arm holder can be fixed at any height and rotation angle, so even if the tone arm is changed, there is no need to drill a hole for fixing the rest stand as in the past. This has the advantage of allowing the armrest to be freely moved to a desired position.
