Description

Braking device for semi-automatic hanging doors {BRAKE APPARATUS FOR SEMIAUTOMATIC HANGING DOOR}

The present invention is a hanging door which can be opened and opened by hanging on a slightly inclined upper rail, and relates to a braking device of the hanging door.

The semi-automatic hanging door is a hanging door which is designed to automatically close a hanging door that is pushed by hand. Conventionally, an automatic closing device with a built-in spring is used, and the hanging door is pulled and closed by the automatic closing device. It is configured to be. Thus, dampers are attached so as not to impact the door contact when closed, i.e. to be closed quietly. By the way, in the semi-automatic hanging door which uses the self-winding attenuation device and the air cylinder damper as a braking device, the closing speed can be closed quietly by adjusting the spring force of the spring or setting the air flow rate of the damper as appropriate. .

However, the semi-automatic hanging doors equipped with the autism device and the damper have a large manufacturing cost, and many failures occur. In recent years, the semi-automatic hanging doors have many types of hanging doors mounted on the inclined rail. It is used. In other words, the open hanging door can be closed independently using its own weight. In this case, the hanging door travels along the inclined upper rail, and as a result, the speed gradually increases to reach the door touching with impact, but the brake device is attached so that the impact does not occur.

4 shows a semi-automatic hanging sentence with a brake. A pulley (b) is attached to the top of the hanging door (a), and the pulley (b) is mounted on the upper rail (c) to hang the hanging door (a). Since the upper rail (C) is inclined in the direction in which the hanging door is closed, the hanging door is closed without using the conventional hand-held device, but the door is closed with an impact at the moment of closing. A brake device (e) is provided so as not to touch the place.

Such a brake device (e) is attached to a hanging mechanism (bar) to which a pulley (b) is attached, and is provided with a pinion (sa). The pinion can rotate, but the brake device has a built-in viscous fluid that resists rotation, and the pinion engages with the rack. That is, the brake acts on the hanging door that slides because it is engaged with the rack.

By the way, in the semi-automatic hanging door apparatus which inclines the upper rail (C) slightly, when the inclination of this upper rail (C) becomes constant, the hanging door width and its weight are determined, and the closing speed of the hanging door (A) is determined. Is determined by itself. Of course, if the inclination angle of the upper rail (c) is increased, the closing speed becomes high, and thus the hanging door width becomes larger, so that the driving distance until closing increases, so that the speed increases and the hanging door weight becomes larger. The closing speed based on the kinetic energy obtained by traveling increases.

However, it is not easy to adjust the inclination angle of the upper rail (c) to the hanging door width or the hanging door weight, and the closing speed can be adjusted by changing the viscosity of the viscous fluid in the pinion. Changing the type of viscous fluid to match this is not realistic and, moreover, not easy to manage. The inclination angle of the upper rail (C) is generally in the range of 0.5 ° to 1.0 °, and further fine adjustment in this range is practically difficult.

When the hanging door is closed, it is desirable to be able to adjust the closing speed not only with a shock, but also without the occurrence of a bounce, as well as to close or speed the closing speed. For example, in elderly homes or hospitals, it is necessary to close relatively slowly than the usual hanging doors. By changing the shaft torque of the pinion, it is possible to adjust the closing speed of the hanging door. However, since the length of the rack is not appropriate, it is almost impossible to adjust.

As described above, the semi-automatic hanging door device using the rack-pinion mechanism as a braking device by inclining the upper rail has the same problem as described above. The problem to be solved by the present invention is this problem, and even if the hanging door width and the hanging door weight are not accompanied by an impact, and can be completely closed without retreading, and at the same time, the closing speed can be adjusted within a predetermined range. Provides a semi-automatic hanging sentence.

The semi-automatic hanging door of the present invention is suspended from the inclined upper rail, and can be automatically closed using its own weight. In the present invention, a brake device is applied to the hanging door that can travel along the upper rail, and a rack-pinion mechanism is adopted, and the pinion attached to the hanging door side is engaged with the rack attached to the rail side. It is functioning.

There is no reason for the novelty of the brake system employing the rack-pinion mechanism. However, in the present invention, by optimizing the rack length, the hanging door is not impacted, the door does not bounce back, and the door is not completely closed in reverse. It can be closed without leaving a gap between the contact and the adjustment of the closing speed (close time). That is, for large (wide) heavy hanging doors, the kinetic energy when closing is large, so the rack length is increased, and conversely, for small (small width) light hanging doors, the rack length is shortened.

However, in the present invention, when the length of the rack is determined, the closing distance index (A) and the hanging door weight index (B) are determined, and the closing distance index when the moving distance from the fully open state to the complete closing is 1200 mm ( A) = 1, hanging door weight index (B) = 1, the rack length is set to 400mm. The hanging door in this case uses a steel surface of 0.8 mm thickness, multiplied by a factor of 0.7 for wood. The dimension of 400 mm is a result of numerous tests. When the size of the hanging door varies, A and B are determined as the size proportional to the closing distance of 1200 mm, and the size obtained by multiplying it by 400 is used as the rack length.

Meanwhile, the rack length may be determined by paying attention only to the weight of the hanging door. In other words, when the weight increases, the hanging door weight is inevitably widened, and the appropriate rack length is set there. Thus, the up and down positions of the rack can be adjusted to smoothly engage the pinion. Hereinafter will be described in detail based on the embodiment of the present invention.

(Example)

1 is an embodiment of the present invention, the hanging door device is provided with a braking device having a rack-pinion mechanism. The hanging door 1 is mounted on the upper rail 2 so that a hanging mechanism 4 having a roller 3 for rolling the upper rail 2 is attached to the top of the hanging door 1. have. Since the upper level 2 has an inclination angle of 0.5 ° to 1.0 ° and is slightly inclined by lowering the front side as in the prior art, the hanging door 1 pushed by hand can be closed independently by its own weight.

The pinion 5 is attached to the hanging mechanism 4 of the hanging door 1, and the rack 6 is provided along the upper rail 2 on the upper rail side. The pinion 5 has a brake device accommodating viscous fluid (for example, silicone oils # 6000 to # 8000), and when the pinion 5 rotates, the pinion 5 is subjected to resistance of the viscous fluid. Just before the hanging door 1 closes, the pinion 5 engages with the rack 6, so that the pinion 5 rotates, and the rolling resistance suppresses the movement speed of the hanging door 1. .

By the way, the hanging door 1 moves along the upper rail 2 from the fully open state, and the pinion 5 is engaged with the rack 6 so that the brake acts and closes silently. In this case, the hanging door When the door 1 is large and heavy, and the distance W to complete closure is large, the kinetic energy becomes large. On the contrary, when the weight of the hanging door 1 is small and closed from the half-open state, the kinetic energy when engaging the rack 6 is small. In the present invention, the rack length is set in consideration of the advantages, and the adjustment width is provided within the range.

The hanging door (1) is based on a distance of 1200 mm from fully open to fully closed, and the effective closing distance index (A) = 1 and the hanging door weight index (B) = 1 in that case, and the rack length. Set L = 400mm. That is, 400mm, which is the rack length when the closing distance is 1200mm, is a number based on many tests, and hanging doors having different closing distances and weights are proportionally related to the closing distance index (A) and the monthly basis based on this 1200mm. The weight index (B) can be determined, and the value obtained by multiplying these indexes by 400 is determined as the rack length.

Table 1 illustrates the case where the closing distances are 1200, 1050, 900, and 750. Based on 1200, other closing distance indexes (A) and hanging door weight indexes (B) are determined. In the case of the closed distance of 1050, it is calculated | required from the calculation formula of A = 1x1050 / 1200 and B = 1x1050 / 1200, and the numerical value of A = 0.87 and B = 0.87 is obtained. The rack length L = 400 × 0.87 × 0.87 ≒ 300. If the closing distance is 900, L ≒ 200, and if the closing distance is 750, L ≒ 150.

The actual rack length (L) is used within the range of about 10% based on the value shown in Table 1 above. In this case, the hanging door 1 uses a panel having a surface material having a thickness of 0.8 mm, and if it is a wooden panel, the hanging door weight index B becomes about 70% compared to that of the steel panel. The length may be 70% of the above Table 1. The rack 6 is a molded article of resin is used, the rack 6 molded in 400mm is used by cutting to the required length.

In this way, the rack length is determined according to the hanging door weight and the closing door closing distance, and the rack torque is used to adjust the shaft torque of the pinion. Fig. 2 shows the shaft torque (axial rotational resistance) of the pinion brake with respect to the closing distance of the hanging door 1, where A is closed from the fully open state and B is closed from the half open state. . As is clear from the figure, when the closing distance is large, the speed at the time of engaging the rack 6 is high, so that the axial torque is large and the brake effect is large. Conversely, when the closing distance is small, the speed at the time of engaging with the rack 6 becomes small, and the shaft torque of the pinion becomes small. Similarly, in the fully open state and the half-open state, the engagement speed with the rack 6 from the half-open state is small even in the hanging door with a large closing distance, and as a result, the shaft torque is necessarily small.

Therefore, the adjustment is actually made in the state of C. If it is close to A, the hanging door may not be completely closed. On the contrary, if it is close to B, the axial torque is too small, causing the hanging door to repel the door. However, in the present invention, since the rack suitable for the hanging door is used, the adjustment range of the closing time of the hanging door is increased, and it is shortened to 2.37 seconds in the early stage and 12.2 seconds in the late stage. This adjustment range is considerably longer than in the conventional case, and it is preferable that the hanging doors of the hospital or the elderly family are closed late, and the present invention can meet the request.

Meanwhile, in the present invention, the rack length may be determined by paying attention only to the weight of the hanging door. That is, the larger the weight of the hanging door is necessarily the larger width of the hanging door, the weight of the hanging door and the width of the hanging door is in proportion. Therefore, the hanging door weight is divided into three categories of 23kg or less, about 23kg ~ 32kg, and about 32kg or more.In the case of about 23kg or less, the rack length is set to about 200mm, about 300mm when about 23kg ~ 32kg and about 400mm when about 32kg or more. .

Then, the module of the pinion which engages the rack is set to three. By setting the pinion module to 3, the impact noise when the rack is engaged with the rack can be minimized, and the engagement margin of the rack-pinion can be increased, and the adjustment during construction is easy. In general, when the module is enlarged, the engagement sound of the rack is increased, but the module 3 is the size of both the suppression of the engagement sound and the adjustment at the time of construction. For example, if module 1.5, the engagement sound becomes smaller, but the adjustment range is -0.5 to +0.5, and for module 3, it is -1.5 to +1.5.

3 shows a braking device, in which a hanging mechanism 4 attached to the upper end of the hanging door 1 is axially supported, and the hanging mechanism 4 has a viscous fluid therein. At the same time as one brake device 7 is attached, a pinion 5 is fixed to the end of the shaft extending from the brake device 7. The rack 6 is attached to one rail stand 8, but the rack 6 is attached to an attachment hole 9 having an L-shaped cross section. The attachment hole 9 is fixed to the rail stand 8, and is attached to adjust the up and down position. That is, since the pinion 5 of the module 3 is used, the vertical position of the rack 6 can be adjusted within the range of -1.5 to +1.5.

As described above, the braking device of the semi-automatic hanging door of the present invention is to determine the rack length according to the weight of the hanging door, and to adjust the vertical position of the rack, and the following effects can be obtained.

In the semi-automatic hanging door device of the present invention, since the rack length is determined according to the weight of the hanging door, when the push-open hanging door is closed along the inclined upper rail by the action of its own weight, it can be closed quietly. In other words, the door is not closed with an impact, the door is not closed against the door, and the door is not completely closed, and no gap is left between the door and the door. By setting the pinion module to 3, the engagement sound with the rack can be suppressed, and the rack position can be adjusted during construction and the engagement with the rack is smooth.
