Abstract

PURPOSE:To test the durability of respective upper and lower drawers of furniture in a short time by mainly providing a lifting body, a driving source thereof, a swing arm, a horizontally reciprocating body and a connecting rod. CONSTITUTION:A chest A is located on a supporting table 40. A lifting body 13 is raised up to a position of a drawer (a) of the chest A by driving a first driving motor 9. The driving motion of the motor 9 is transferred to a synchronizing shaft 7 to rotate respective spiral rods 4 via bevel gears 8, 6 so that the lifting body 13 is moved in the vertical direction. When the lifting body 13 reaches a desirable position, the motor 9 is stopped and a top section of a connecting rod 36 is connected to one of the drawers (a). Then, a second driving motor 14 is driven to rotate a rotating body 20 so that a swing arm 23 is swung via a crank arm 22. A horizontally reciprocating body 28 reciprocates in the horizontal direction via a vertical arm 32. As a result, drawer (a) is repeated to be opened and closed by means of the rod 36 so that the testing thereof is executed. The driving motor permits to improve the speed and accuracy of the testing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a product performance tester for testing the durability of various furniture and electric appliances having drawers, chairs with casters, strollers with casters, boxes with doors, etc. Regarding

[0002]

2. Description of the Related Art Conventionally, most of the performance testers of this type are made by hand, and the structure is such that the reciprocating motion of a cylinder is used to make the tip of a cylinder rod fixedly installed at a predetermined position in furniture. It was a simple thing to connect the drawers appropriately and repeatedly open and close the drawers.

Therefore, as a performance tester for furniture up to a certain size, it is possible to use it by using an auxiliary support stand or not, but when the furniture is large, it is inevitably one. Since the position of the top drawer also becomes high, it is difficult to test the performance of each drawer, and the height of the product side must be constantly adjusted, such as by superimposing several auxiliary support bases, so work efficiency is improved. It had the drawback of being bad.

Further, since the cylinder rod is limited to forward and backward movements, only various furnitures and electric appliances having drawers are subject to the test, such as chairs with casters, strollers with casters, boxes with doors, etc. The durability of the performance of various products could not be easily tested.

In addition, the performance tester utilizing the reciprocating motion of the cylinder has difficulty in adjusting the stroke of the cylinder and also has a limit in reciprocating speed. There was a drawback that the test at speed could not be done freely.

[0006]

In view of the above-mentioned conventional drawbacks, the present invention is desired simply and in a short time without adjusting the height of the product side whose performance is to be tested for each drawer. You can test the durability of each top and bottom drawer of furniture and electrical products, and easily test the performance durability of various products such as chairs with casters, strollers with casters, boxes with doors, etc. Can, in addition,
It is to obtain a product performance tester that can test the accuracy of the reciprocating motion of the product (including a part) freely.

[0007]

A product performance testing machine according to the present invention comprises a machine frame, a plurality of screw rods rotatably mounted on the machine frame, and a plurality of screw rods screwed with these screw rods. An elevating body having a coupling tube, a drive source provided on the elevating body, a swing arm provided on the elevating body so as to swing by the driving force of the drive source, and a lower end portion of the swing arm, Also, a horizontal reciprocating body that reciprocates while being guided by a guide shaft arranged on the lifting body via a sliding portion,
The horizontal reciprocating body comprises a connecting rod having a rear end attached thereto and a tip end attached to a product to be tested.

[0008]

[Function] For example, the organized dance to be tested is placed on the support base. Next, the first drive motor is driven to raise and lower the elevating body to the position of the drawer of the rearranging dance which is desired to reciprocate repeatedly. When the first drive motor drives the lifting body, the driving force is transmitted to the synchronous shaft and each screw rod, and as a result, the lifting body moves up and down.

Next, when the lifting body reaches a desired position, the first drive motor is stopped, and the tip of the connecting rod on the lifting body side is appropriately connected to one of the drawers of the organizing dance.

After that, the second drive motor is driven. When the second drive motor is driven, the driving force is transmitted to the swing arm via the rotating body and the crank arm. Therefore, the horizontal reciprocating body reciprocates in the horizontal direction via the guide block, the horizontal shaft, and the like.

As a result, the drawer of the organized dance is repeatedly opened and closed by the connecting rod. In this case, if the product to be tested is a chair with casters, the chair will cycle back and forth.
