Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot-operated internal jam lock attached to the indoor side of a movable door installed inside or outside a building.

At present, the majority of locking/unlocking of internal locks attached to movable doors used in buildings is performed by directly grasping manual operation members such as knobs and thumb-turns with the fingertips, and most of them are used. The operator has no choice but to touch the manual operation member.

On the other hand, in recent years, people's wariness against bacteria and viruses has expanded to an amazing extent, and the heightened awareness of epidemic prevention is remarkable. Bacteria and viruses attached to fingers can be taken into the body by touching the face with those fingers or by carrying the food you grabbed to your mouth. Therefore, the number of people who feel that they do not want to touch things that have been touched by an unspecified number of people, such as equipment and tools in public places, is increasing. It is only natural to think about reducing the number of things you touch as much as possible and thoroughly washing your hands and disinfecting after touching them.
Under these circumstances of changing social awareness, we believe that it is meaningful to reduce the number of things that people have no choice but to touch in public places. It is up to you to do

First, Japanese Patent Application Laid-Open No. 2002-200000 discloses a device for locking and unlocking without touching a manual operation member of a lock installed on a movable door. This patent describes a foot-unlocking toilet door intended to prevent the development of food poisoning by touching an unlocking knob that has been contaminated with bacteria by another user. By stepping on a foot pedal arranged on the floor on the partition wall side, the latch projecting from the door side by being biased by the latch receiver on the partition wall side against the opening type door suspended by the hinge. , the latch receiver connected to the foot pedal rises, the latch is pushed back, the engagement with the latch receiver is released, the toilet door opens, and the user can unlock the door without using fingers. The patent is for a door. Also, from the point of view of equipment costs, it is worth noting that automatic hinges that open with springs are used to avoid motorization, and to use inexpensive mechanisms.

Similarly, Japanese Patent Application Laid-Open No. 2002-200002 proposes to operate a lock with a foot without using hands. Normally, a person bends down and grasps a knob or the like to move the stopper rod of the drop lock of a gate that opens and closes, but this device operates a lever connected to the stopper rod by foot. be. By stepping on the lever with the foot, the stopper rod rises and comes out of the hole, and the curved plate-shaped spring maintains the unlocked state of the gate. A function is added to complement the operation by simple movements using the feet.

In addition, Patent Document 3 is a patent that attempts to lock and unlock a door lock without a person touching it using a locking/unlocking device using sensor technology. The door has an open/close sensor, the toilet has two sensors that detect the presence of people, the floor has a pressure sensor that detects the presence of people based on their weight, and a timer that measures the elapsed time to help with proper lock operation. It is a patent that realizes a door locking and unlocking device that does not require human contact. It is a locking/unlocking device that consists of various electrical elements such as a non-contact sensor that uses infrared rays, light, etc., a motor that drives a door that opens and closes, and a control device that integrates them.

Regarding the point of performing the locking/unlocking operation without touching the lock provided on the movable door, Patent Document 1 is for unlocking the locking device of the toilet door that is opened by an automatic hinge using a spring. A latch projecting from the door side to the partition wall side is provided inside the partition wall, and is unlocked by pushing back the latch. This mechanism is operated by stepping on a pedal provided on the floor inside the room. With this mechanism, a mechanism for pushing back the protruding latch when the door is closed must be assembled inside the partition wall, which complicates construction on site and may lead to an increase in construction costs. In addition, since the pedal system is directly attached to the floor, there are concerns about foreign matter entering the pedal system and corrosion of the pedal system itself. Furthermore, assuming the actual use of the foot-operated unlocking door of this patent, even if an automatic hinge that opens and measures for stepped pedal operation are taken, some cause such as mischief, mischief, etc. It is also conceivable that the door will be closed when there is no one in the room, and that it will hinder the use of the room after that.

In terms of operating the lock with the foot, Patent Document 2 proposes using a lever for operating a drop lock installed on a gate. When the stopper rod is pulled up before the gate is opened, it can be easily unlocked by stepping down the lever with the foot. can be opened and closed safely. However, when locking this drop lock, the stopper rod in the raised state must be lowered, that is, the lever must be raised by the foot. Assuming actual use, the upper surface of the toe is usually used to kick up the lever, which may stain or damage the shoe. In addition, if the footwear is partially exposed, such as women's sandals, the bare feet may be directly soiled, and operability may be difficult. Therefore, it is necessary to fully consider what kind of operation is performed with which part of the foot.

In addition, Patent Document 3 can be said to be one of the smartest patents in that it makes full use of electric motors and electronic devices without directly using hands and feet, and is completely touchless from opening and closing to locking and unlocking the door. . First of all, there is no problem with operability because there is no need to touch doors or locks. However, the initial cost of equipment such as many sensors, drive motors, and control devices will increase, and it is expected that a large amount of maintenance will be required on an ongoing basis. Furthermore, if the power source is lost due to a power outage, it will be difficult to use the door. In addition, according to this patent document, if it is applied to the door of the toilet, unexpected actions caused by users who do not need to worry about other people's eyes in private spaces, such as unnecessary work and mischief. It may be necessary to assume and improve the specifications of the touchless equipment.

The present invention provides an internal locking lock provided as necessary in a generally used movable door, an internal locking lock installed on the indoor side IN of a movable door having a door panel 1 that can be freely opened and closed, and a user It is a foot-operated internal lock that locks and unlocks using 65 feet. That is, it is characterized by being an internal locking lock that can be locked and unlocked by operating with the foot of the user 65, and has the effect that the user 65 can lock and unlock without touching the lock portion with his or her fingers. . The movable door provided with the foot-operated inner locking lock of the present invention is expected to be used in public facilities such as government offices, commercial facilities, medical and welfare facilities, etc., which are mainly used by an unspecified number of people. be done.

In addition, as mentioned in the background that led to the invention of the present invention, in recent years, public health awareness such as epidemic prevention has increased to an unusual degree. Under such circumstances, it is almost impossible for people to keep away from places, facilities, and equipment used by an unspecified number of people in their social lives. For example, there is a public toilet at a station that is used when going out by public transportation such as a train. Even if you are worried about bacteria and viruses and think "I don't want to touch toilet facilities with my palms and fingertips as much as possible", I usually do not touch the doorknobs and lock knobs 103 (see Fig. 19) of the private toilet room. The reality is that we have no choice but to pay attention while thoroughly washing and disinfecting our hands afterward. Therefore, by attaching the foot-operated inner locking lock of the present invention to those doors, it is possible to eliminate the need to grip the lock knob 103, etc., which conventionally had to be touched on a general toilet door. be. If this can reduce the anxiety of the user 65 as much as possible and prevent infection with bacteria and viruses due to direct contact of the user 65 as much as possible, the foot-operated inner tightening lock of the present invention can be used. is considered to fulfill its role satisfactorily.

Regarding the foot-operated inner tightening lock of the present invention, in describing the mode for implementation with a specific example, a lock that has been generalized as a conventional manual inner tightening lock, such as a sickle lock and a deadbolt, will be described. A lock mechanism that performs the function of final tightening such as a lock or a hammer lock is used as it is, and the emphasis is on the lock operation using the foot and the operation object, which is the essence of the present invention, so that the individual lock mechanism Details regarding the format may be omitted.
Hereinafter, an example of the form which carries out the present invention is given and explained.

FIG. 1 is a schematic diagram showing a sickle lock, which is a foot-operated inner tightening lock of the present invention housed inside a door panel 1, from the indoor side IN of a lower rail type sliding door type door 11. FIG. This is a sliding door type door 11 in which a door panel 1 slides on a lower rail 17 laid between a fixed wall 15 on the door tip side and a fixed wall 16 on the door bottom side, and is substantially in the center of the door panel 1 on the door tip side of the door panel 1. It is a door that can be closed inside with a sickle lock at the height of . Normally, a thumb-turn 104 or the like for operating the sickle lock with fingers is arranged near the lock mechanism, but in the example of FIG. It protrudes from the lower part of the door panel 1 on the door tip side. The pedal 19 moves up and down on the surface of the door panel 1 along the pedestal 18 . This is an example of the operating body 2 in the foot-operated sickle lock of the present invention. It is directly connected to the sickle member 25 or indirectly via a connecting member 26, and the sickle member 25 can be driven to perform locking and unlocking. When the door panel 1 is closed to the fixed wall 15 of the door end wall and the user 65 depresses the pedal 19 located in the upper part of the pedal movable range, the sickle member 25 rotates or slides through the connecting member 26, thereby rotating or sliding the pedal. The tip protrudes, and can be inserted into and removed from a strike 28 installed on the door frame 27 on the side of the door or on the surface of the fixed wall 15 on the side of the door, and can be locked. Then, the pedal 19 locked at the lower part of the pedal movable range by the alternate operation mechanism inside the door panel 1 is depressed again, thereby releasing the lock of the alternate operation mechanism and pushing the pedal 19 vertically upward. After returning to the upper part of the pedal movable range, the driven sickle member 25 is housed inside the locking mechanism of the door panel 1 to complete unlocking.
An example in which the sickle lock, which is the foot-operated inner tightening lock of the present invention, is housed in the sliding door type door 11 has been described above. It may be placed on the surface, or it may be installed on the hinged door 12 in some cases. The movable door referred to in the present invention includes the movable door panel 1 for both the sliding door type door 11 and the hinged door type 12, and the fixed wall 15 on the side of the sliding door type door 11 which is not movable (if there is a door frame 27). ), the fixed panel 13 on the front side of the hinged door 12, the fixed wall 16 on the bottom side of the sliding door 11, and the non-movable door 12 of the hinged door 12. It is composed of a fixed panel 14 on the buttock side.

Also, the large handle 29 attached to the door panel 1 is convenient for the user 65 to slide the door panel 1 left and right using the back of the hand or elbow without gripping it with fingers. Furthermore, when the lock mechanism of the sickle lock as shown in FIG. It is possible to prevent damage to surrounding members.

FIG. 2 shows a representative example of the operation body 2 of the pedal 19 having a plate-like portion to which force is applied by foot operation. FIG. 2(1) shows a single-pedal operating body 2 having the above-described alternate operation mechanism. FIG. 2(2) shows a two-pedal type operating body 2. By depressing the left pedal 19 in the figure, the right pedal 19 is raised, and conversely, from that state, the right pedal 19 is depressed. Lowering will raise the left side. Therefore, in any of the examples, locking and unlocking can be performed only by depressing the pedal 19 vertically downward with the foot. FIG. 2(3) shows the operating body 2 of the vertical plate 31 that slides in the horizontal direction, has a size and area sufficient for the user 65 to touch with one foot, is substantially perpendicular to the door panel 1, and It stands almost vertically. Locking and unlocking can be performed by pushing the operating body 2 of the vertical plate 31 in either the left or right direction with a foot.

The alternate operation of the one-pedal operating body 2 is that once the pedal 19 is depressed, it is locked by a mechanical lock mechanism provided inside, and the pedal 19 can be depressed even if one foot is released. When the pedal 19 is depressed again, the pedal 19 returns to the original upper position and becomes unlocked. It is called a holding type because the pedal 19 remains in the position when the lock mechanism is activated, and it operates like a knock cam mechanism found in a so-called knock type ballpoint pen.
FIG. 3 is a schematic diagram of an example in which a rotary cam type alternate operation mechanism is applied to the foot-operated sickle lock of FIG. A rotating cam 20 having notches 21 at both ends rotates freely inside a frame 22 in contact with the peripheral side surface, and is pivotally supported between the pedal 19 and a connecting member 26 . However, a mechanism for urging the pedal 19 vertically upward with an elastic body or the like is omitted.
Here, the internal structure from the unlocked state to the locked state will be described. When the unlocked pedal 19 (left view in FIG. 3) is depressed, the sickle member 25 interlocked with the connecting member 26 pops out, and the rotating cam 20 slightly touches the bottom portion 22a inside the frame 22. Tilt clockwise. Incidentally, after this, the state in which the rotating cam 20 is in contact with the stepped portion continuing to the bottom portion 22a is the depressing limit of the pedal 19. As shown in FIG. After that, as soon as the stepped pedal 19 starts to be returned, the notch 21 of the rotating cam 20 engages with the inner projection 22b inside the frame 22 (the solid line diagram in the right figure of FIG. 3), and the operation is maintained. Locked state. Next, the internal structure from the locked state to the unlocked state will be described. When the locked pedal 19 is depressed again, the notch 21 of the rotary cam 20 and the inner projection 22b inside the frame 22 are disengaged, and the rotary cam 20 comes into contact with the slope of the bottom 22a inside the frame 22. and further rotates clockwise (dashed line diagram in the right diagram of FIG. 3). If the foot is removed and the pedal 19 is lifted, the notch 21 of the rotating cam 20 can no longer engage with the inner projection 22b inside the frame 22, and the inner projection 22b moves further along the side surface 20a. It rotates around (the dashed-dotted line in the right figure of FIG. 3), finally reverses 180 degrees from the initial state, returns to the upper position, and returns to the unlocked state.

FIG. 4 shows an example of the interlocking state inside the lock mechanism of the foot-operated sickle lock having the operating body 2 of the two-pedal type. FIG. 4(1) is a schematic diagram viewed from the front, and FIG. 4(2) is a schematic diagram viewed from the side. The two pedals 19 are divided into a locking pedal 23 shown on the left side of FIG. 4(1) and an unlocking pedal 24 shown on the right side of FIG. 4(1). When the sickle member 25 inside the lock mechanism rotates clockwise or counterclockwise about the fixed shaft 34 as a center fulcrum, the tip of the sickle member 25 goes in and out of the door tip of the door panel 1 . A connecting rod 35 connects a pedal shaft 32 extending to the inside of the door panel 1 on the extension of the locking pedal 23 and a movable shaft 33 of the sickle member 25. When the locking pedal 23 is lowered, the sickle member 25 rotates clockwise and the tip of the sickle member 25 rotates clockwise. It protrudes and becomes locked. An intermediate shaft 37 positioned substantially in the center of the two pedals and fixed inside the door panel 1 is relayed, and the pedal shaft 32 and the locking pedal 23 extend toward the inside of the door panel 1 on the extension of the unlocking pedal 24. The pedal shaft 32 extends to the inside of the door panel 1 and is connected by a pedal connecting rod 36 . The holes for the respective shafts of the pedal connecting rod 36 are concentric on the side of the locking pedal 23, and the holes in the approximate center of the pedal connecting rod 36 and the holes on the side of the unlocking pedal 24 are located between the pedals moving up and down. Each has an oblong hole 38 for length adjustment. When the locking pedal 23 is stepped down, the unlocking pedal 24 is pushed up, and conversely, when the unlocking pedal 24 is stepped down, the locking pedal 23 is pushed up, resulting in seesaw-like motion. Therefore, simply by depressing the pedal 19 in the pushed-up state, if it is the locking pedal 23, the tip of the sickle member 25 will protrude, and if it is the unlocking pedal 24, the sickle member 25 will be retracted, and the foot will be pulled. It is possible to lock and unlock the operation type sickle lock.

FIG. 5 is a schematic diagram showing a deadbolt lock, which is a foot-operated internal lock, viewed from the indoor side IN of the hinged door 12. As shown in FIG. This deadbolt lock is unlocked by operating a slidable deadbolt 41 housed inside the door panel 1 and inserting and removing the tip of the deadbolt 41 into and out of the strike 28 arranged on the fixed panel 13 on the door front side. Locking is performed.
This hinged door type door 12 consists of a door panel 1 that is positioned between a fixed panel 13 on the side of the door tip and a fixed panel 14 on the side of the door trailing edge, and that rotates while being hung from the fixed panel 14 on the trailing side of the door by a hinge 42. A lockable movable door with a deadbolt lock at the bottom of the side. Since the door is of the swing door type, it also has an antibacterial panel 43 as a target for the user 65 to push the door panel 1 . In the case of a normal deadbolt lock, the deadbolt 41 is moved by a finger-operated knob 103 or the like, but in the example of FIG. A plate-like body 45 is fixed to protrude from the outer periphery of a rotating shaft 44 that protrudes vertically to the indoor side IN. This is an example of the operation body 2 in the foot-operated deadbolt lock of the present invention. It has a function of locking and unlocking in conjunction with each other.
When the door panel 1 is closed to the fixed panel 13 on the side of the door, the user 65 pushes the plate-like body 45 in one direction with one foot, and the rotary shaft 44 rotates and is transmitted to the lock mechanism, and the door panel 1 is closed. The deadbolt 41 housed inside protrudes, and the tip of the deadbolt 41 can be inserted into and removed from the strike 28 of the fixed panel 13 on the side of the door to be locked. Next, the plate-like body 45 is pushed away in the direction opposite to the first operation, so that the rotary shaft 44 rotates in the opposite direction, and the deadbolt 41 is housed inside the door panel 1 to complete unlocking.
An example in which the deadbolt lock, which is the foot-operated internal tightening lock of the present invention, is housed in the hinged door 12 has been described above. May be faced on top.

FIG. 6 shows the operation body 2, which is composed of a rotating shaft 44 projecting perpendicularly from the lower part of the door panel 1 on the side of the door, and one or a plurality of plate-like bodies 45 projecting from the rotating shaft 44. The left figure is the front view, and the right figure is the side view. The operating body 2 of this embodiment includes a rotating shaft 44 and a plate-like body 45 having a size and area large enough for a user 65 to touch with one foot.
The example of FIG. 6(1) is an operation body 2 formed of a single plate-like body 45 projecting and fixed from a rotating shaft 44 projecting vertically from the lower part of the door panel 1 shown in FIG. It is in the initial state hanging vertically downward from 44 . As described above, the user 65 pushes the plate-like body 45 to the left or right with one foot and acts on the lock mechanism via the rotating shaft 44 to lock and unlock the door. Although not shown here, the initial state may be set vertically above the rotating shaft 44, or may be set to an initial state in which the rotating shaft 44 is projected horizontally to either the left or right direction. In these cases, the user 65 can operate the plate-like body 45 by pushing it away or stepping on it. That is, the initial state of the single plate-like body 45 is not limited to vertically downward, and can be set arbitrarily.

Alternatively, the example of FIG. 6(2) can be considered. This is an operating body 2 consisting of a rotating shaft 44 projecting vertically from the lower part of the door panel 1 and two plate-like members 45 projecting from the rotating shaft 44 and fixed. It is the same as in the case of one sheet of plate-like body 45 that can be performed. In the operation body 2 shown in FIG. 6B, two plate-like bodies 45 fixed to project from the rotary shaft 44 form a substantially right angle (≈90 degrees) with each other. When one plate-like body 45 is horizontal as an initial state, the other plate-like body 45 hangs vertically downward, and the user 65 steps down the horizontal plate-like body 45 with one foot to rotate the rotation axis. When 44 is rotated, the other plate-like body 45 is also rotated to a horizontal state. For the interlocking lock mechanism, for example, if the initial state is the unlocked state and the locked state is set when the other plate-like body 45 is lowered with the foot and the other plate-like body 45 becomes horizontal, then either state can be operated with one foot. It is possible to avoid soiling or damaging the instep side of one foot of the user 65, that is, the upper surface of the shoe or foot. However, it goes without saying that the angle formed by the two plate-like members 45 is not limited to a substantially right angle and can be arbitrarily set according to conditions such as a lock mechanism.

FIG. 6(3) shows the operation body 2 in which three plate-like bodies 45 are fixed by extending from the rotating shaft 44 by adding one more. In this example, two plate-like bodies 45 are fixed substantially symmetrically (≈180 degrees) to the rotating shaft 44, and the remaining one plate-like body 45 is attached to the two plate-like bodies 45, respectively. At the same time, the operation body 2 has three so-called T-shaped plate-like bodies 45 fixed so as to form a substantially right angle (≈90 degrees). For example, if the initial unlocked state is a state in which two axially symmetric plate-like members 45 are horizontal and the remaining one hangs vertically downward, locking and unlocking is performed by stepping down in the same manner as in FIG. 6(2). In addition, as shown in FIG. 6(1), the plate-like body 45 hanging vertically downward can be pushed away either to the left or right to lock and unlock. can be done. Having a plurality of operation methods leads to improved convenience for the user 65 when performing operations using feet, which do not have the flexibility of fingers. However, as in the case of the two plate-like bodies 45, the angle formed by the three plate-like bodies 45 can be arbitrarily set according to the conditions of the lock mechanism and the like.

FIG. 7 is a schematic diagram showing the operation using one leg in FIG. 6(3), depicting two different motions at the same time. The operation of horizontally pushing away the plate-like body 45 hanging vertically downward from the T-shaped operating body 2 consisting of the rotary shaft 44 and three plate-like bodies 45 is shown on the right side of the drawing. The one leg 47 and the stepping down one leg 48 on the left side of the drawing represent the motion of stepping down one of the plate-like bodies 45 in the horizontal state vertically downward. Both of them represent operations for locking and unlocking the linked internal tightening locks.

FIG. 8 shows an example of the internal linkage of a foot-operated sickle lock mechanism having a T-shaped operating body 2 consisting of a rotary shaft 44 and three plate-like bodies 45 . This sickle lock is of a type in which a sickle bolt 51 slides inside a cylindrical guide 52, and a pin 53 protrudes from the side surface of the sickle bolt 51 near the rear end in the longitudinal direction. Inside the door panel 1 with the surface of the T-shaped operation body 2 interposed therebetween, a deformed operation plate 54 having a fan-shaped notch at substantially the center of the circumference of a semi-disc is provided on a rotary shaft 44. is fixed to Therefore, when the T-shaped operating body 2 rotates, the deformed operating plate 54 connected by the rotating shaft 44 also rotates together. If the T-shaped operating body 2 is rotated by stepping down the plate-shaped body 45 on the door tail side of the T-shaped operating body 2 or by pushing away the vertically hanging plate-shaped body 45 in the direction of the door, One fan-shaped notch end surface 55 of the deformed operation plate 54 hooks a pin 53 protruding from the sickle bolt 51 to slide the sickle bolt 51 so that the tip of the sickle bolt 51 protrudes from the door. The sickle bolt 51 protrudes further, rides on a rotating small disc 56 installed inside the fixed wall 15 on the side of the door, and slides upward, whereby the tip of the sickle bolt 51 hits the engagement piece 57, and locking is completed. do. On the other hand, the T-shaped operating body 2 is rotated by stepping down the plate-shaped body 45 on the front side of the T-shaped operating body 2 or pushing away the vertically hanging plate-shaped body 45 in the direction of the door bottom. Then, the other fan-shaped notch end face 55 of the deformed operation plate 54 hooks the pin 53 protruding to the sickle bolt 51 to slide the sickle bolt 51, and the tip of the protruding sickle bolt 51 is pulled back to release the sickle bolt. 51 is housed inside the cylindrical guide 52 to complete unlocking.
The sickle bolt 51 of this embodiment corresponds to the "sickle member 25" in the claims, but since it slides inside the cylindrical guide 52, it is called "sickle bolt 51" here for convenience. do.
Although the T-shaped operation body 2 made up of three plate-like bodies 45 has been described, the fan-shaped notch end surface 55 of the deformed operation plate 54 hooks the pin 53 protruding from the side surface of the sickle bolt 51, thereby The shape of the deformed operation plate 54 (for example, polygonal, rod-like, flat plate-like, circular, cloud-like, etc.) and the number of plate-like members 45 are not limited as long as the plate 51 can be slid.

FIG. 9 is a schematic diagram of a foot-operated sickle lock provided with the operation body 2 of FIG. This sliding door type door 11 is suspended from an upper rail 61 laid on the upper wall surface by a hanging metal fitting 63 having wheels 62 on the upper part of the door panel 1, and slides. The inside can be tightened by providing a sickle lock. The operation body 2 of the foot-operated sickle lock shown in FIG. Locking/unlocking is performed by acting on a lock mechanism linked to the rotating shaft 44 inside the housing 1 . The door panel 1 abuts against a stopper 64 fixed on the surface of the fixed wall 15 on the side of the door to close the door. The body 45 is stepped down with one foot to protrude the sickle member 25 housed inside the locking mechanism linked to the rotary shaft 44, and the strike 28 drilled in the lower stopper 64 is inserted and removed to lock. be able to. Conversely, the user 65 steps down with one foot the other of the two plate-like bodies 45 fixed to the rotating shaft 44, which has been brought into a horizontal state by the stepping-down motion when the user 65 locks. Then, the protruding sickle member 25 is pulled back into the lock mechanism to complete unlocking.
At this time, it is desirable that the door panel 1 is provided with a large handle 29 so that the user 65 does not have to use his fingers. 9, the user 65 can press the door panel 1 with a larger part of the body such as the back of the hand, the elbow, or the shoulder, or raise the foot 66 on the operation side. It is possible to balance the unstable posture by leaning on the large handle 29 with the elbow or shoulder while standing only on the leg 67 on the shaft side. Furthermore, if the large handle 29 is extended to the lower part of the door panel 1, the user 65 can use his/her knees, expanding the body parts that can be used other than the hands and fingers and increasing the options for operation. The large handle 29 should be associated with the foot operated internal jamming lock of the present invention. Also, for the sliding door type door 11 having a foot-operated internal lock, the shape of the large handle 29 as shown in FIG. May.

On the other hand, it is also possible to use a hammer lock instead of a sickle lock. FIG. 10 is a schematic diagram showing the foot-operated latching lock of the present invention from the indoor side IN of the sliding door 11. As shown in FIG. A hook-shaped lock 69 of a rotatable rotating arm 68 is attached to a strike 28 arranged on the front end side surface of the door panel 1. It locks and unlocks by attaching and detaching.
Generally, unlike sickle locks in which the lock mechanism is often housed inside the door panel 1, the hammer lock has a rotating arm 68, which is a tightening part, exposed to the outside. A foot-operated lock is a lock that is installed at the bottom of the door and is operated with one foot. In the example of FIG. 10, a rotating arm 68 corresponding to a lock mechanism and an operating body 2 for rotating the rotating arm 68 are attached to the fixed wall 15 on the side of the door, and a hook-shaped tip portion 69 of the rotating arm 68 and a detachable strike 28 are attached to the door panel. It is a foot-operated lock that is installed on each side of the door of 1. Conversely, it is also possible to install the rotating arm 68 and the operating body 2 on the door leading side of the door panel 1 and the strike 28 on the fixed wall 15 on the door leading side. This is due to the fact that the locking mechanism is relatively simple and is exposed to the outside, and it is said that there is a high degree of freedom in installing the equipment, as with conventional locking locks operated by fingers. There are advantages.

FIG. 11 is a schematic diagram of an example in which a rotary block 71 is used for the operation body 2 provided in the foot-operated sickle lock of the present invention. The operating body 2 of this embodiment includes a rotating shaft 44 and a rotating mass 71 . The rotating mass 71 of FIG. 11 is cylindrical, and the outer peripheral surface of the cylinder has a surface, area, and volume sufficient to allow contact with one foot of the user 65, especially the sole of the foot. , a center hole 72 is formed in a direction passing through the approximate centers of the bottom surfaces of the cylinders. On the other hand, a rotating shaft 44 linked to a lock mechanism inside the door panel 1 protrudes vertically from the surface of the door panel 1 . The columnar rotating mass 71 and the rotating shaft 44 are integrated by inserting the rotating shaft 44 into the center hole 72 of the rotating mass 71 to the root and fixing them. Therefore, the user 65 touches the outer circumference of the rotary block 71, i.e., the side surface of the cylinder, and rotates the rotary block 71, thereby acting on the lock mechanism via the rotary shaft 44 to lock and unlock. Here, a user 65 carrying a baggage 73 presses the large handle 29 with his elbow to close the door, and moves the sole of the foot circumscribing the cylindrical rotating mass 71 in a direction perpendicular to the rotating shaft 44 to move the rotating mass 71 . is rotated in the circumferential direction to lock the foot-operated sickle lock. In addition, the rotary block 71 or the operation display 70 on the door panel 1 helps the user 65 to operate smoothly.

FIG. 12 shows a representative example of a rotating block 71 as the operating body 2 of the present invention. FIG. 12(1) shows a rotating mass 71 having a vertical cross-section columnar shape in FIG. 11, the left side being a side view and the right side being a perspective view. A center hole 72 is formed in the center of the bottom surface of the cylinder shown in the side view, and the rotating shaft 44 linked to the lock mechanism is inserted and fixed therein. Furthermore, anti-slip projections 74 are arranged on the side surface of the cylinder, which serves as the operation surface of the rotating mass 71, to increase the frictional resistance between it and the sole of the foot, thereby further improving the operability. FIG. 12(2) shows a rotation block 71 having a polygonal prism shape (hexagonal prism shape) in longitudinal section, and the user's 65 foot soles can be placed on the corners of the boundary between the side surfaces to facilitate operation. FIG. 12(3) shows a rotating block 71 using a columnar body with a special cross section. It is a columnar body having a triangular section of Reuleaux in vertical section, and it is possible to rotate the rotating shaft 44 by about 120 degrees with one operation by the foot. It may be a great advantage for operations using parts such as legs, which are difficult to make continuous fine movements. Further, the non-slip grooves 75 on the sides are intended to improve the operability, like the non-slip projections 74 . FIG. 12(4) shows a rotating mass 71 formed by a columnar body having a star-shaped vertical cross section. The side corners corresponding to the apex of the star shape help the operation by the sole of the foot, and it may be said that the operation body 2 is excellent in design. Of course, the vertical cross-sections of these columnar bodies are not limited to the above four types, and include shapes with rounded corners, Reuleaux polygons with bulging sides, and the like.

Further, the rotary block 71 as the operation body 2 has been selected to be a columnar body because it can be attached to the surface of the door panel 1 and is easy to operate with the foot, but it does not necessarily have to be a columnar body. The three-dimensional body may have any shape as long as the user 65 can touch it with one foot and roll it with his foot to operate the rotary shaft 44 connected to the lock mechanism. Furthermore, it may be an asymmetric solid as long as it can rotate around the rotating shaft 44 inserted through the center hole 72 . The rotary shaft 44 is rotatably supported by a bearing (not shown) or the like. Further, other "shafts" such as the fixed shaft 34 and the support shaft 79 may also have a base end fixed inside the door panel 1, or may be supported by a bearing or the like.

As the operation body 2 provided in the foot-operated inner tightening lock so far, the flat plate-like body 45 that the user 65 steps down with one foot or pushes off in the lateral direction has been described. Don't forget the button type operating body 2 that is pushed forward with the tip of the foot. In the first place, the simple operation of pressing with the tip of the foot is a very effective operation means in a situation where a very delicate operation cannot be expected, that is, the user 65 operates with the foot.
In general, if the button is pressed with a finger, it is sufficient if it is as large as the tip of the finger. It is desirable that the button be of a size large enough to cover the width of the user's 65 shoe. For example, if the button is one size larger than the electric open/close button installed at the height of the waist of the fixed wall 15 on the side of the door of the multi-purpose toilet, it is not only operable but also useful as the operating body 2. It seems that sufficient awareness can be secured.

FIG. 13 is a schematic diagram of a foot-operated sickle lock in which the operating body 2 is composed of two buttons. Of the locking button 76 (operation display 70 "CLOSE" in the figure) and unlocking button 77 (operation display 70 "OPEN" in the figure) arranged side by side at the bottom of the door panel 1 on the indoor side IN, the The pressing leg 49 represents the action of pressing the unlocking button 77 with the tip of the foot in order to store the sickle member 25 and unlock it. Normally, when we talk about button operation, we expect locking and unlocking by activating an electric lock mechanism with an electric switch. In consideration of time management, it may be desirable in some cases to be able to operate the lock simply by pressing the button. Of course, if new technology spreads the use of electric mechanisms that are inexpensive, durable, highly stable, and even capable of supporting backups in emergencies, it would be better to replace them with those.

Here, FIG. 14 shows an example of the interlocking state inside the lock mechanism of a foot-operated sickle lock having an operating body 2 consisting of two buttons. FIG. 14(1) is a schematic view from the front, and FIG. 14(2) is a schematic view from the side. The two buttons are a locking button 76 on the left side and an unlocking button 77 on the right side. When the sickle member 25 inside the lock mechanism rotates counterclockwise or clockwise around the fixed shaft 34 , the tip of the sickle member 25 goes in and out of the door tip of the door panel 1 . A semi-connecting rod 78 to which the sickle member 25 is driven is located inside the door panel 1 and can rotate about a support shaft 79 provided in the middle of the semi-connecting rod 78 . The longer rod extending from the support shaft 79 of the semi-connecting rod 78 has an oblong hole 38 at its tip, and the movable shaft 33 of the sickle member 25 is connected through the oblong hole 38. there is On the other hand, the shorter rod extending to the opposite side has a spherical tip. The locking button 76 is maintained in a protruded state by a spring 81 inside the button. A flexible cable 82 extends from behind the locking button 76 and the other end of the flexible cable 82 passes through a curved cylindrical tube 83 just before the spherical tip 84 of the semi-connecting rod 78 . is guided by Further, a block 85 having a dish-shaped recess is attached to the tip of the flexible cable 82 , and the flexible cable 82 is pushed out along the cylindrical tube 83 by pressing the locking button 76 . The ball tip 84 can then be pressed to move the semi-connecting rod 78 and rotate the sickle member 25 to lock the foot operated sickle lock. An oblong hole 38 in the semi-connecting rod 78 is responsible for length adjustment during rotation. In addition, the length of the rod extending from the support shaft 79 of the semi-connecting rod 78 is determined by the rod principle to ensure a sufficient moving length for rotating the sickle member 25 with a small pushing distance of the locking button 76. Helpful. On the other hand, the unlocking button 77 has the same mechanism as the locking button 76, and similarly, pressing the unlocking button 77 moves the semi-connecting rod 78 to the opposite side and rotates the sickle member 25. , the foot-operated sickle lock can be unlocked.

Since the operation body 2 provided in the foot-operated inner locking lock of the present invention is operated by the user 65 using his/her feet, the operation body 2 is positioned below the floor surface 86 on the surface of the door panel 1 or the fixed wall 15 on the side of the door. It is essential that it protrude from the position. Furthermore, considering the situation in which the user 65 operates by raising and lowering one leg, it is easy to require that the operating surface, which is the portion operated by touching the operating body 2 with the foot, must be within a certain height range. I can imagine. In other words, there is a limit to how much the user 65 can raise one leg.
Therefore, in considering the height at which many users 65 can raise one leg without difficulty, it was decided to refer to the Japanese Building Standards Act. Although the building standards change depending on the country, the upper limit of the height of one step of a staircase in general buildings under the Building Standards Act is the upper limit of the height h from the floor surface 86 to the operation surface of the operation body 2 . That is, by setting the height h from the floor surface 86 to the operation surface of the operation body 2 to be within a range of 230 mm or less vertically above the floor surface 86, a foot-operated inner tightness having an operation body that is easier to operate. We can provide locks.

FIG. 15(1) is a schematic diagram showing that one pedal 19 of the operating body 2, which is composed of two pedals 19 projecting from the lower surface of the door panel 1, is depressed. In this case, even if the unlocking pedal 24 is positioned at the upper limit of the pedestal 18, the height h from the floor surface 86 including the operation surface of the pedal 19 on which the foot is placed to the operation surface of the operation body 2 is a virtual surface Sh. It shows that it is below the imaginary plane S at a height of 230 mm from the floor surface 86 .
Similarly, FIG. 15(2) is a schematic diagram showing that the operating body 2 having the T-shaped plate-like body 45 of FIG. 6(3) is stepped down. An imaginary line Lh of height h from the floor surface 86 including the operation surface of the plate-like body 45 on which the foot is placed to the operation surface of the operation body 2 is below the imaginary line L of 230 mm in height from the floor surface 86. showing.
These operating bodies 2 are examples of each. millimeters < h ≤ 230 millimeters”.

Further, the operation body 2 attached to the foot-operated inner locking lock of the present invention does not necessarily have to be a flat plate, and may be a curved plate. FIG. 16 shows a vertical plate 91 on which the operation body 2 is curved and which is installed on the surface of the door panel. Since the vertical plate 31 of the operating body 2 against which the user 65 presses the foot is thus curved or bent, the one leg 47 pushed away by the user 65 is caught in the curve or bending. You can expect an improvement in performance.

Furthermore, the operation surface of the operating body 2 provided in the foot-operated inner lock of the present invention does not necessarily have to be a flat surface, and may be a flat surface having unevenness on the surface, or a flat surface having a mesh or holes here and there. Alternatively, it may be a virtual surface formed by continuously juxtaposing linear or dot-like small areas. Concavo-convex portions of the operation surface of the operation body 2 have already been described with respect to the rotating block 71 in FIGS. 12(1) and 12(3).
FIG. 17 is an example of a pedal 19 with various operating surfaces. In FIG. 17(1), a large number of gaps 92 are provided on the surface of the pedal 19, which is the operation surface. The effects of these gaps 92 include improved operability due to increased frictional resistance with the sole, lighter weight of the pedal 19, and improved design. FIG. 17(2) shows a pedal 19 in which a plurality of plate-like objects are vertically arranged with their short sides 93 continuously arranged at substantially equal intervals. ) is a pedal 19 in which a plurality of sticks are erected with their longitudinal directions substantially vertical, and the tip surfaces 94 of the sticks are continuously arranged at substantially equal intervals. In both cases, a virtual surface formed with a small area at the end or pointed end serves as the operation surface, but the frictional resistance between the sole and the sole of the foot increases to improve operability, and dust and dirt on the surface of the pedal 19 are reduced. One of the effects is that it is difficult for dirt to accumulate.
The above is an example of the operation body 2 of the pedal 19, but it is of course applicable to other operation bodies 2 provided in the foot-operated inner tightening lock of the present invention.

A locking device is required on the indoor side IN of the toilet room or toilet cubicle to ensure a temporary private space.
FIG. 18 is a schematic diagram of a foot-operated inner locking lock of the present invention installed on the indoor side IN of a private toilet room. A urinal 97 is hung on a double wall covered with a top plate 96 on a wall surface 95 of the toilet room, and a private toilet room surrounded by a partition panel 98 is provided beside it, and a western-style toilet is provided in the toilet room. 99 is installed. The entrance of the toilet private room is a hinged door 12, and a foot-operated deadbolt lock is installed at the lower part of the door panel 1. - 特許庁Here, FIG. 19 shows an example of a conventional manual operation member. A locking knob 103 (left figure) is installed directly below the handle 101 of the sliding door 11, and a thumb turn 104 (right figure) for operating the deadbolt 41 is installed directly above the handle 102 of the hinged door 12. be.
This foot-operated inner tightening lock eliminates the need for the user 65 to directly touch the manual operation member of the conventional inner tightening lock with fingers, thereby solving one of the hygiene problems in the toilet room and reducing the risk of infectious diseases. can also contribute.

Further, on the surface of the door panel 1, fixed panel or fixed wall, or on the surface of the operating body 2, there is a guideline or result for the operation of the operating body 2 provided in the foot-operated inner tightening lock, specifically, the operating body 2. A configuration (operation display 70) in which the explanation of the operation method of , arrows, etc. are indicated by symbols or characters is also conceivable. Note that the fixed wall refers to the fixed wall 15 on the front side of the door and the fixed wall 16 on the rear side of the door. Further, the fixed panel refers to the fixed panel 13 on the front side and the fixed panel 14 on the rear side of the hinged door 12 .

In addition, each drawing shows each embodiment, but for the purpose of making the drawings easier to understand, some of the configurations are omitted, simplified, and transparentized. Of course, the invention is not limited to only the embodiments shown here.
