Description

[Detailed description of the invention] The present invention relates to a table such as an ironing board, and its purpose is to improve the operability and the reliability of holding legs when folding and standing up the legs rotatably provided on the top plate. do.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes an upper plate whose frame is made of an aluminum plate or the like, and the upper surface is made of a lath plate, a mat, or the like.

2 and 2' are legs rotatably attached to the upper plate 1;
' is a connecting rod whose one end is connected to the leg 2.degree. 2', and whose other end is fitted into guide grooves 5, 5' provided in the support 4 so as to be freely slidable.

The guide grooves 5, 5' have locking portions 6, 6' of the connecting rods 3, 3' when the legs are in the upright position, and locking portions 6, 6' of the connecting rods when the legs are in the folded position. 7.7' is provided.

Reference numeral 8 denotes a spring body provided corresponding to the guide grooves 5, 5', which is attached to the support body 4 at a fixed point P close to the inner end of the guide grooves 5, 5', and its free end is connected to the guide groove 5. , 5', and always urges the connecting rods 3, 3' toward the locking portions of the guide grooves 5, 5'.

The spring body 8 consists of free ends 9, 9', a straight part 10, 10' and a bent part 11.11'.

In the above structure, the operating operation and function thereof will be explained. First, when the legs 2, 2' are folded toward the upper plate 1 side as shown by the two-dot chain line in FIG. ' is in the state shown by the two-dot chain line in FIG. 3, and the ends of the connecting rods 3, 3' are pushed into the locking parts 7, 7' of the guide groove by the spring body 8.

In this state, the connecting rod 3,
3' comes into contact with the spring body, and the spring body becomes a cantilever beam, and the legs 2, 2'
is held in the folded position.

To stand up legs 2 and 2' from this state, step 3
The connecting rod 3 is moved in the direction of arrow a in the figure against the spring force of the spring body 8.
, 3', and connect the connecting rod 3 from the locking parts 7, 7' of the guide groove.
, 3' are released.

When the legs 2, 2' are rotated in the direction of arrow C in FIG. 1, the ends of the connecting rods 3, 3' move in the guide grooves 5, 5' in the direction of arrow C in FIG. 3.

When the connecting rods 3, 3' are about to enter the locking parts 6, 6', the spring body 8 has its ends 9, 9' connected to the support body 4.
The spring body 8 is in the state shown in FIG. 5 in which it is in contact with the spring body 8, and the spring body 8 temporarily becomes a beam supported on both sides, and the spring load becomes stronger.

By further rotating the legs 2, 2' in the direction indicated by the arrow against this spring force, the spring body 8 is connected to the locking parts 6, 6' while in contact with the connecting rods 3, 3'. Try to plunge the end of the rod into it.

When the legs 2, 2' are erected and rotated to the upright position, the ends of the connecting rods 3, 3' enter the locking parts 6, 6' through the bent parts 11° 11' of the spring body 8. I am made to do so.

This state is maintained by the spring force of the spring body 8.

In this way, when the legs are in the down position, the spring body biases the connecting rods in a cantilevered state, so when the legs are in the upright position, only a light force is applied to the connecting rods. You can move to

In addition, when the legs are in a standing position, the end of the spring body comes into contact with the support body and becomes temporarily supported on both sides, so a strong spring force acts on the connecting rod, resisting this spring force. By rotating the legs, the connecting rod can quickly move to the locking portion and shift to the upright position.

Therefore, a dual action mechanism is obtained with a single spring body that uses different spring forces when the leg is moved to the upright and downward states, providing reliable operability and firmly maintaining the state.

It has excellent features such as being able to do these things with a single spring body.

Claims (1)

[Scope of utility model registration request] An upper plate, a pair of legs with one end rotatably attached to the upper plate, a pair of connecting rods with one end connected to the legs, and a pair of guides that fit and guide the other end of the connecting rod. A groove and a spring body provided corresponding to the guide groove, the spring body having a fixing point in a portion close to the inner groove of the guide groove, and having a free end along the guide groove. The spring body is provided in close proximity to the outer end of the guide groove, and when the leg is folded toward the upper plate in the inverted state, the spring body presses the connecting rod in a cantilever state, and the leg is erected to be in the upright state. The table includes folding legs in which the free ends of the spring bodies are brought into contact with the upper plate and press the connecting rods in a state where they are supported on both sides.
