Description

[Detailed description of the invention] This invention uses one of the support legs that support the outer frame of a product such as a washing machine as an adjustable leg, so that when it is installed on the floor (installation surface), the balance of the outer frame is uniform. This invention relates to an apparatus for vertically adjusting an outer frame of a device to ensure final locking.

Traditionally, fixed support legs have been used to support the outer frame of a device (such as a washing machine) on the installation surface, but since the installation surface is not necessarily flat, the height must be adjusted slightly after installation. Therefore, consideration was given to making at least one of the support legs adjustable.

FIG. 1 is a longitudinal cross-sectional view of a conventional device, for example, one in which one of the support legs supporting the outer frame of a washing machine is an adjustable leg, where 1 is the outer frame of the washing machine, 2 is the body, and 3 is the operation panel. , 4 is a lid, 5 is a water tank for washing and dehydration, 6 is a pulsator, 7 is a motor, and 8 is a rotational force transmission mechanism, and the rotation of the motor 7 is transmitted by a V-belt 9 to the transmission mechanism 8.
It is transmitted from the pulsator 6 to the water tank 5 via the pulsator 6. That is, during washing, the pulsator 6 is rotated,
During dehydration, the water tank 5 is rotated and centrifugal force is used through the dehydration hole 10 to perform centrifugal dehydration. The water receiver 11 is for receiving washing water and dehydration liquid, and the water receiver 11 is for receiving washing water and dehydration liquid.
2 and drain the respective liquids to the outside of the machine using a drainage hose 13. 14 is a reinforcing plate to which the water receiver 11 and the transmission mechanism 8 are attached. Suspension mechanisms 15 are provided at the four corners of this reinforcing plate 14.
are respectively provided and suspended from the upper part of the outer frame 1 by rods 16. 17 is a support leg, and the outer frame 1
It is fixedly attached to the four corners of the lower surface, and adjustment legs 18 are usually provided at one location and at multiple locations as necessary.

FIG. 2 is a sectional view of a conventional adjustment leg portion, in which the adjustment leg 18 is attached to an adjustment leg mounting plate 20 made of a substantially U-shaped metal plate that is attached and fixed to the inside of the bottom of the outer frame 1 from below with screws 19. It penetrates. Movement in the radial direction is stopped by a through hole 21 in the adjustment leg mounting plate 20 and a through hole 22 in the outer frame 1. A spring 23 is installed between the bottom surface of the outer frame 1 and the lower surface of the adjustment leg 18,
Outer frame 1 is pushed upward. Since the support legs 17 support the weight of the entire outer frame 1 evenly, the spring constant of the spring 23 is set so that the other support legs 17 and the adjustment legs 18 are at the same height. A retaining pin 24 is set on the upper part of the adjusting leg 18 to prevent it from coming off. Pierce nut 2 on adjustment leg mounting plate 20
A hexagonal bolt 26, which is screwed into the pierce nut 25 by caulking 5, is insert-molded and integrated into the adjustment knob 27. An insertion hole 1A is formed in the outer frame 1 into which the adjustment knob 27 is inserted. Therefore, when the adjustment knob 27 is screwed in, the adjustment leg 18 is pressed through the pierce nut 25 to stop movement in the thrust direction.

As explained with respect to Figures 1 and 2,
The adjustment leg 18 in a conventional device includes an adjustment leg mounting plate 20, screws 19, and a pierced nut 25 on the mounting plate 20.
The hex bolt 26 that is screwed into the pierce nut 25 is required, and there are many parts, and a separate part for fixing the adjustable leg is required, and the tightening force required to fix the adjustable leg is required. The outer frame plate had to be thicker because of its strong surface, and the paint on the tightening parts was likely to peel off, causing rust to form there and resulting in an unsightly appearance.

The present invention eliminates the drawbacks of the conventional equipment, and provides an equipment outer frame vertical adjustment device that requires fewer parts, can reduce the thickness of the outer frame plate, and does not cause peeling of paint or rust at the tightening part, making it unsightly. The purpose is to obtain.

The outer frame vertical adjustment device (hereinafter referred to as adjustment device) of the present invention will be explained with reference to FIGS. 3 and 4.

FIG. 3 is an enlarged sectional view of the main parts of the adjusting device in an embodiment of the present invention, and FIG. 4 is an exploded perspective view of the present invention.

3 and 4, the same reference numerals as in FIGS. 1 and 2 correspond to the same parts.

Reference numeral 28 denotes an adjustment leg of the present invention, the lower tip of which penetrates through the through hole 22 at the bottom of the outer frame 1, and the upper part bent at a substantially right angle to form a rounded portion 30, which extends to the tip outside the outer frame 1. A threaded portion 29 is provided, and this threaded portion 29
A stepped portion 31 is formed between the rounded portion 30 and the rounded portion 30 . Reference numeral 32 denotes an elongated hole provided on the side surface of the outer frame 1, the width of which is made smaller than the diameter of the adjusting leg 28. Therefore, when the threaded portion 29 of the adjusting leg 28 protrudes from the elongated hole 32 serving as the protrusion opening of the outer frame 1, the threaded portion 29 is fixed to the side wall by the stepped portion 31. Reference numeral 33 denotes an adjustment knob which is screwed into a threaded portion 29 protruding from the side wall of the outer frame 1, and has a contact surface 34 on the side in contact with the side wall of the outer frame 1.
are provided in one piece. 35 is a guide plate A, 36 is a guide plate B, and the guide plate A35 is connected to the adjustment leg 2.
It is inserted so as to come into contact with the stepped portion 31 of 8,
It is usually formed from a washer-shaped sheet metal. Guide plate B3
6 is integrally provided with an engaging claw portion 37, which is fitted into a fitting hole 38 provided in the side wall of the outer frame 1 to connect the guide plate B36.
is becoming fixed. Also, guide plate B3
6 has an elongated hole 3 provided in the outer frame 1 in the center as a protrusion opening.
A through hole 39 having the same shape as 2 is provided. As a result, when the threaded portion 29 of the adjustment leg 28 passes through the elongated hole 32 of the side wall, it overlaps with the guide plate A35 in contact with the stepped portion 31, the side wall, and the guide plate B36, and the outer frame 1
The outer peripheral surface of the elongated hole 32, which serves as the protrusion opening, is the guide plate A35.
and the guide plate B36, and when the adjustment knob 33 is turned in the screwing direction, the contact surface 34
is fixed in contact with the side surface of the outer frame 1. In addition, 40 is an outer frame reinforcement part fixed to the bottom of the outer frame 1,
It is made of a substantially triangular sheet metal forming a hole 41 that overlaps with the through hole 22. In addition, although there is one adjusting leg 28 in the figure, it is also possible to have a plurality of intermediate adjusting legs 28 of the support leg 17 if necessary.

Since the present invention has the above-mentioned configuration, the outer frame 1
The bottom surface of the support leg 17 and the adjustment leg 28 support the bottom surface of the support leg 17 and the adjustment leg 28. When the adjustment knob 33 is loosened when the support leg 17 and the adjustment leg 28 are installed, the elasticity of the push-up spring 23 inserted into the adjustment leg 28 will cause the entire support leg to Move up and down to maintain even balance. Therefore, if the outer frame 1 is moved up and down along the elongated hole 32 serving as the protrusion opening, and the adjustment knob 33 is screwed in and fixed at a stable place, the adjustment leg 28 of the present invention is not a straight bar shape, but has a rounded part 30 and a step. The part 31 and the threaded part 29 are integrally provided and inserted through the through hole 22 on the bottom surface of the outer frame 1, and the threaded part 29 is passed through the elongated hole 32 provided on the side as a protrusion opening, and the guide plate A35,
By pressing the side wall with the guide plate B36 and pressing it against the stepped portion 31 with the adjustment knob 33, the positioning can be performed automatically.

As explained above, the present invention, like the conventional example,
The adjustment leg mounting plate 20, the pierce nut 25, the stop pin 24, the mounting screw 19, etc. are no longer necessary.

Since the outer frame 1 is pressed against the guide plate A35 and the guide plate B36 by the adjustment knob 33, the pinching force of the outer frame 1 becomes larger as the outer diameters of the guide plate A35 and the guide plate B36 are increased. , the holding force is improved, but inversely proportional to this, the rotational force of the adjustment knob 33 only requires a small force, and even an ordinary housewife can reliably set the adjustment leg 28 with a light force. Furthermore, since the insertion area of the outer frame 1 increases, the strength of the outer frame 1 can also be increased, and it is also possible to reduce the thickness of the outer frame plate to reduce costs. Furthermore, since the paint applied to the outer frame 1 is not directly affected by the screwing of the adjustment knob 33 but is supported by the guide plate B36, there is no scratching or peeling, and there is no possibility of rust or other unsightly appearance. Further, when the adjusting leg 28 is slid up and down, the sliding is performed smoothly because the guide plate is large. Therefore, the present invention can increase the holding force of the adjustment knob 33 with an extremely simple structure, reduce costs by reducing the thickness of the outer frame, rationalize mechanical parts, and provide even more reliable holding force. The present invention provides an equipment outer frame vertical adjustment device that can ensure extremely high quality such as sliding movement and prevention of damage to the outer frame.
