Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrical device equipped with an elevation angle adjustment device such as a fan fILaI.

Conventionally, for example, in a tabletop fan, there were
Figure (: As shown in the figure, it was t °C.A fan (...1) A toad stand (21) made of Konsei IIw with switches, etc., and the base (2)
A connecting body (5) that is held between a pillar (31 and two prongs s4 provided at the tip of the pillar t31) protruding from the
The main body of the electric fan (61 is composed of a motor (not shown), a blade (not shown) driven by the a-motor, and a guard covering the a-mode is shown in FIG. 51). The connecting body (5) is pivoted on the pivot (7) at the fork (41).The connecting body (5) has a continuous sawtooth-shaped recess (8) on its outer periphery. A locking body 01 biased outwardly by a spring GO is housed in a recess 191 formed at the bottom center of the two forked portions (4). The tip of 01) is in the recess (9).
It is formed in a triangular shape that corresponds to °C. The locking body 0
11 is the pillar (3) that passes through the pivot @171t' when the connecting body (5) is facing in the horizontal direction as shown in FIG.
The center of the center is located (a center line (A1 direction C2) and the locking body 0υ moves T.Then, the contact surface between the recess (8) and the locking weight; bisects the center 1lltAJv By forming the #1 plane of the isosceles triangle that goes down with the mat, the locking force that prevents the rotation of the connecting body (51 in the th direction IUI/\\ rotation #I! and the rotation of ; -\ in the F direction) The locking force that prevents the movement T is the same.Therefore, the true identity of the electric fan f61 (J) supported by the connecting body (5) (from the second)
There is always a force acting on 5) to force it to rotate downward. The rotation operating force of the connecting body (5) is greater in the upward direction.

The force of the spring becomes smaller in the downward direction, making it impossible to obtain a substantially constant operating force, and in order to prevent inadvertent downward rotation, the force of the spring is reduced. The electric fan has to be made large, and if it is made large, the operating force becomes large and it is difficult to operate.
When it is rotated in the downward direction IDI, the horizontal length from the pivot (7) to the center of gravity increases, and the downward force required to rotate it in the downward direction 1 increases.

As the main body of the fan (61) rotates in the downward direction, a substantially constant holding force cannot be obtained unless the locking force is increased.

In view of the above points, the present invention differs in the locking force of the connecting body to the support body depending on the rotational locking position or the locking/unlocking direction.
Electric sl' with approximately constant holding force and operating force of the connecting body
The purpose is to provide this information to A1.

A locking body VW biased by a spring is attached to the connecting body and the support, and a plurality of engaging portions are formed on the other side to which the locking body engages and disengages. The engaging/disengaging force l of the mating portion is different depending on the two twists or the engaging/disengaging direction.

The 4th prisoner, Figure 5, and 6th cause are shown below.T1. The present invention will be explained based on second and third examples. 8. Structural parts that are the same as the conventional ones shown in FIGS. 1 to 3 are not shown in the drawings and their explanations will be omitted.

In the first example shown in the fourth factor, the locking body QD is made into an isosceles triangular shape with the center IAIv divided into two equal parts as in the conventional case. An engaging portion (22 m) (22 m) with which the locking body Q1 engages T
b) (22C)Y The locking bodies Cl1l are formed in the isosceles triangular recesses, and the engagement members @(221 (22

22m) and the locking body Qll is large, and the locking force between the shallow engaging portion (220) and the locking body C+υ is small.

Therefore, the locking force when the connecting body (-) is rotated to the ten-direction peak is large, and the locking force when the connecting body is rotated upward (υ) is small, so that the connecting body ( 5) holding force can be obtained.

Fig. 5 shows the second actual figure [N is the isosceles triangular shape with the center HtAJ1 divided into two equal parts and T, as in the conventional case.
The opening angle from the center 11tA) is t and 1 °C. The engaging portion (24&) (24) with which the locking body (c) engages
b) (240) is a V-shaped recess with two slopes 6 and 2 faces T of the locking body Ω (j, s. Said engagement!Is (24m) (24b) The opening angle from the center of the locking part (241) located in the middle of (24G) is the same as that of the locking body. Rotate the connecting body (5) to open downward. When the engagement part (24m') is engaged with the locking body 1, the opening angle (γ14! The opening angle to is t°
The engaging portion C240), in which the connecting body (5) is rotated in an upward direction of 1 tJl, is engaged with the engaging portion C240) at an opening angle of (υ)− in the upward direction from the central thread. ) becomes t〈β and is the opening angle to the downward opening! f becomes t.
Therefore, are the locking force and the locking force in the downward direction iDl of the locking body G that overlaps the engaging portions (24&) and (241)) the same when the opening angles are the same?

The engagement and disengagement force to the upward IUI is due to the opening angle (γ1 of t minus γ) of Manki Kaishato (24 m), and the engagement s(
24a) The engagement/disengagement force for 1 m is the engagement portion (24I)) 5
This is smaller than the engagement and disengagement force between the two. 1L.The locking force and the locking force in the downward direction 101 of the locking body that descends on the engaging portions (24b) and (24Q) are
Since the opening angle of AQ) is equal to β, the locking force and the locking force against the engaging portion (2Ac) are equal to the locking force against the retaining portion (241). It is smaller than the force and the disengaging force. Above the locking body a! The engagement and disengagement forces for 1/I are the same since the opening 8i1jlt is at the same angle t.

The third example shown in FIG. 6 has a triangular shape in which the opening angle IAI in the upward direction from the center of the locking body GY is smaller than the opening angle in the direction G. - The engaging part 1 (2) I171et is formed in a triangular recess where the machining locking body is engaged. Yotsu°C @
The locking force and locking force in the direction F of the locking body G with respect to group (2) (2) (2) are larger than the locking force in the upward direction (in the direction F). Sword of Shogun (5)■
The operation in the opposite upward direction tU+ and the downward surface appearance in accordance with gravity have been explained.
In the #j1 example, it is also possible to change the depth V of the gold part as in the first example, or the first example. Various embodiments are possible, such as changing the shape of the locking body to the second embodiment as in the third embodiment. Although the locking body is housed in the support column, it is also possible to store the locking body in the connected V3 body and form the engaging part in the V support column. The engagement and disengagement is carried out between the bottom surfaces of the two forked parts, but it is not particularly necessary to engage and disengage the two prongs by 8, and the engagement may be performed between the side surface of the connecting body and the inner surface of the forked part by 1152%.

As described above, the present invention has a connecting body that is mainly used for electrical equipment, and a locking body that is biased by the second spring of the interlocking body that has intercourse with the B connecting body as a rotating target. , a plurality of locking rods to which the limb locking body engages and disengages on the other hand, and the locking force between the locking body and the engaging portion is applied to the engaging portion or is varied depending on the direction of engagement and disengagement. .

The locking force at the rotational locking position of the connecting body or the locking/disengaging force between the rotational operation directions can be varied, and the operation force can be kept substantially constant.
