Description

[Detailed Description of the Invention] The present invention mainly relates to a mounting structure for a balance weight used in a small German-type equatorial mount.

Conventionally, as shown in Figures 1 and 2,
A rod 3 as an iron rod attached to a declination body 2 that houses a motor drive device in the equatorial mount body 1
Attach the heavy balance weight 4 to the set screw 5.
While fixing it in an appropriate position, the plug portion of the power cord 7 from the separately provided battery box 6 was inserted into the outlet portion 8 attached to the declination body 2 to supply power to a motor (not shown).

Therefore, this power cord 7 has the disadvantage that it becomes difficult to operate the telescope tube (not shown) attached to the equatorial mount body 1 because it becomes tangled and becomes a hindrance to the operation of the telescope tube (not shown).

Another disadvantage is that the battery box 6 must be carried around, resulting in a large amount of luggage.

In addition, 9 is the control box and lead wire 10
is connected. 11 is a polar body.

The present invention was developed in view of the above-mentioned drawbacks, and its contents will be explained below based on the embodiment shown in FIG.

Reference numeral 15 denotes a balancer mounting cylinder designed to accommodate batteries, and is mainly configured to accommodate a plurality of dry batteries 16, but may also be configured to accommodate rechargeable batteries such as Kadonica (trademark).

This balancer mounting cylinder 15 is a declination body 17.
There are 18 screws attached.

Reference numeral 19 denotes a balance weight as a balancer, which is fixed to the balancer mounting cylinder 15 with a set screw 20 and a pressing pin 21. This balance weight 19 can be moved and fixed as appropriate in the direction of arrow A or B.

Reference numeral 22 denotes a conductive terminal that protrudes from the declination body 17 into the balancer mounting cylinder 15.
6, and is connected in series with an external switch (not shown) of a motor drive device (not shown) attached to the declination body 17, and closes the motor circuit (not shown) when the switch is ON. and switch
It is configured to open the motor circuit (not shown) when it is OFF.

Therefore, there is no need for a power cord as in the past.
Reference numeral 33 is a cap, and 24 is a conductive spring, which acts to press the dry battery 16 against the conductive terminal 22 at all times.

Next, the mode of use of the present invention having the above configuration will be explained.

A dry battery 16 is always stored in a balancer mounting cylinder 15 screwed 18 onto the declination body 17, and the dry battery 16 is pressed against a conductive terminal 22 by a cap 23 via a conductive spring 24. Next, the balance weight 19 is appropriately moved in the direction of the arrow A or B, and fixed at an appropriate position via the set screw 20 and the pressing pin 21.

Therefore, the present invention has the structure and function as described above, and in particular, a cylinder body for attaching a balancer is attached to the declination body, a plurality of dry batteries or rechargeable batteries are stored in series, and the declination body is equipped with a cylinder body for attaching a balancer. Since it is connected to the body's motor drive device, there is no need for a power cord from the battery box as in the past, and the equatorial mount can be operated smoothly without the risk of getting tangled. There is no need to carry a separate battery, and the benefits are enormous.
