2. Description of the Related Art In general households and offices, there are many products having members that can be opened and closed in the vertical direction, such as front desks of writing desks and back lids of pianos.
These products may be freely rotated in any direction by the hinges, thereby injuring a finger with the opening / closing member, or the heavy opening / closing member may suddenly descend to damage the product body by impact. For this reason, the inventor of the present invention has
For example, Japanese Patent No. 59347 proposes an opening / closing suppressing device that does not cause a sudden downward turning of an opening / closing member by appropriately braking a rotating shaft in both up and down directions.

In this opening / closing suppression device, when suppressing the closing operation of a large and heavy opening / closing member, it is necessary to use a large one in accordance with the load of the opening / closing member. In addition, since this opening / closing suppressing device similarly suppresses both upward turning and downward turning of the opening / closing member, if high braking is set so as to suppress downward turning of the heavy opening / closing member, upward turning of the opening / closing member is also considerable. On the other hand, if low braking is set so that the upward rotation of the opening and closing member is easy, the downward braking of the opening and closing member may be insufficient.

In order to solve this problem, Japanese Patent Laid-Open No.
In the one-way braking device disclosed in Japanese Patent No. 344524, when the opening / closing member is turned upward, the shaft body idles in the hole of the pinion, so that the opening / closing member can be easily turned upward, and the opening / closing member is turned downward. In this case, a sudden downward turn is braked by rotating the brake together with the shaft. This device is suitable for preventing upward acceleration of the opening / closing member and for quickly achieving upward rotation, and is preferably attached to a drawer of furniture or a rotating window.

[0005]

Problems to be Solved by the Invention
The device disclosed in No. 4 makes it extremely easy to rotate the opening / closing member upward, but since the shaft is not braked at all during the upward rotation, the opening / closing member can be acted upon even by a slight upward impact. Is likely to open. In this device, a plurality of grooves are provided at equal intervals on the outer peripheral surface of a small collar, and a set of a small roller and a compression spring is stored in each groove, and the structure is relatively complicated and the number of parts used is large. , Manufacturing costs are likely to be high.

The present inventor has further studied a braking device attached to a heavy movable body such as a touch panel of a register, and as a result, proposes a product in which the above-described one-way braking device is further improved. Although the object of the present invention is to brake both the downward and upward turning of the movable body,
It is an object of the present invention to provide a partial braking device in which a torsion coil spring is fitted to a shaft body to strongly brake downward turning as compared with upward turning. Another object of the present invention is to provide a partial braking device in which the movable body does not turn even when a slight upward impact acts. Another object of the present invention is to provide a partial braking device capable of adjusting a rotational resistance that suppresses turning of a movable body.

[0007]

In order to achieve the above-mentioned object, a partial braking device according to the present invention comprises: a shaft supported by a movable member or a mounting member fixed to an apparatus main body; And a plastic braking member attached to the device body or the movable body and press-fitting the shaft body. Further, the coil spring is generally a known torsion coil spring, one end of which is directly or indirectly locked to the shaft body and the other end of which is directly or indirectly locked to the braking member.
Locking via a protective bracket or the like.

[0008] The partial braking device according to the present invention includes, in place of the braking member, a plastic braking member that is closely fitted to the shaft, and an inner periphery that is attached to the main body or the movable body and corresponds to the outer peripheral surface of the braking member. It may be provided with a protective fitting having a surface, and a fastening member for fastening the braking member inward via an extension of the protective fitting. In this configuration, the inside diameter of the relatively thin braking member is variable, and when no clamping force is applied by the clamping member, the inside diameter of the braking member is slightly larger than the diameter of the shaft.

In addition, this biased braking device is a plastic braking member which is fitted tightly on a shaft body and has a longitudinal groove of an appropriate length formed from an end, instead of the braking member, and an adjustment screwed into the shaft body. And a nut. This braking member is integral with or separate from the housing. If the braking member is separate from the housing, the inclined outer peripheral surface of the front portion of the braking member is fitted into the inclined inner peripheral surface of the housing through-hole, and the braking member is urged toward the housing with an adjustment nut to thereby rotate the shaft. tighten. If a sleeve having an inclined inner peripheral surface is provided, the sleeve is fitted on the inclined outer peripheral surface at the rear part of the braking member, and the sleeve is urged toward the braking member and the housing by the adjusting nut to tighten the shaft. When the braking member is integral with the housing, the inclined inner peripheral surface of the sleeve is fitted to the rear portion of the braking member, that is, the inclined outer peripheral surface of the housing projection, and the sleeve is urged toward the braking member, that is, the housing by the adjustment nut.

As a result, the rotational resistance is small due to the difference between the torque of the spring 8 and the torque of the spring 8, so that only upward turning can be easily performed.

The coil spring 8 can generate the maximum torque at a desired turning position of the movable body by appropriately setting the mounting position in the torsion direction.
For example, it is preferable that substantially the maximum torque be generated when the touch panel 2 which is a movable body is turned to a horizontal position, and that the generated torque is set to be small when the panel is turned to a vertical position. In this case, if the panel 2 is turned and stopped at an appropriate inclined position, even if the panel 2 is relatively heavy and the inclined position is at an angle close to horizontal, the panel 2 can be kept stationary at the inclined position for a long time.

For example, the fixing pin has a flat head, and its axis passes through the extension. After passing through the hole, caulking is performed. In this configuration, the inner diameter of the braking member 14 is variable, and the inner diameter of the braking member 14 is slightly larger than the diameter of the shaft when no tightening force is applied by the tightening member 20.

In FIG. 11, instead of the braking member 10, the partial braking device includes a plastic braking member 24 which is fitted tightly on a shaft body and has a longitudinal groove 22 having an appropriate length from an end portion. An adjusting nut 26 screwed into the shaft body may be provided, and a sleeve 28 having an inclined inner peripheral surface may be further provided. The braking member 24 is a circular bipyramid or a simple trapezoidal cone (not shown) as shown in FIG. 11, and the braking member may be integral with the housing or may be configured so as not to use a sleeve.

Although not shown,
When the braking member is integral with the housing, the sleeve is fitted on the rear portion of the braking member, that is, on the inclined outer peripheral surface of the housing protrusion, and the adjustment nut biases the sleeve toward the braking member or the housing.

A longitudinal groove 22 of an appropriate length is formed from one end or both ends of the braking member 24, and a stopper (not shown) that fits into the longitudinal groove of the braking member 24 on the inclined inner peripheral surface of the housing. Is preferably installed. 9 to 11, the tightening force of the braking member can be adjusted by screwing the adjusting screw 20 or the adjusting nut 26.

The partial braking device 1 includes a shaft body 5 having an L-shaped mounting bracket 7 fixed to a rear end face, and the mounting bracket is bolted to a movable body to support the shaft body 5 horizontally. The shaft body 5 is an elongated round bar having an odd-shaped cross section at both ends. After being press-fitted into the through hole 11 of the plastic braking member 10, the coil spring 8 is loosely fitted.
Next, a large-diameter stopper plate 31 is inserted at the front end and a modified hole of the L-shaped mounting bracket 7 is inserted at the rear end face, and each is caulked.

The braking member 10 is a rectangular piece having a triangular side surface as shown in FIG. 4, and is a hard injection-molded product of a wear-resistant engineering plastic (for example, a carbon-containing polyacetal resin). The through hole 11 provided at the center of the side surface of the braking member 10 has an inner diameter slightly smaller than the diameter of the shaft so that the shaft 5 can be press-fitted. The braking member 10 is bolted to the inclined surface of the support 32, and the support is further fixed above the register main body 3 with a bolt or the like.

Therefore, the panel 2 having a considerable weight can be stopped at an appropriate inclined position, and even if the panel 2 is slightly touched, the panel 2 remains stationary at that position for a long time. On the other hand, when the touch panel 2 is pulled upward, the difference between the frictional resistance and the torque of the spring 8 reduces the rotational resistance, so that the panel 2 can be pulled up relatively easily. Therefore, it is easy to change the tilt position of the touch panel 2 according to the height of the user.

In FIG. 5, when the movable body is to be pushed down, a frictional resistance is generated between the outer peripheral surface of the shaft body 44 and the curved inner peripheral surface of the member 50 of the braking member 45 at this time. The torque is applied to increase the rotational resistance.
On the other hand, when the movable body is pulled up, the rotational resistance of the movable body is reduced due to the difference between the frictional resistance and the torque of the spring 46.

[0034]

According to the partial braking device of the present invention, although the braking force acts in any of the turning directions of the movable body, the torque of the coil spring is added during the downward rotation, so that the rotational resistance is large, and the upward braking of the upward rotation is not performed. In this case, the torque of the coil spring is subtracted, and the rotational resistance is reduced. Therefore, when the movable body is turned upward, the movable body is easily turned upward and can be stopped at an arbitrary inclined position. On the other hand, when the movable body is turned downward, the frictional resistance of the coil spring is reduced. By applying a torque and braking strongly, a sharp downward turn is prevented when the movable body is closed. The partial braking device can be attached to a touch panel of a register, an opening / closing lid of a large-sized copying machine, a front panel of a writing desk, and the like.

In the partial braking device according to the present invention, since the braking force acts also in the upward direction, the movable body does not turn only when a slight upward impact is applied, and the movable body is not rotated by the upward slight shock. It will prevent movement or damage.
This partial braking device has a small number of parts and can be manufactured relatively inexpensively. In addition, this biased braking device can adjust the tightening force of the braking member relatively easily by screwing in the adjusting screw or the adjusting nut, and in the case of a heavy movable body, reduces the rotational resistance so as not to rotate naturally from the inclined state. Can be larger.
