Patent No. 3145858 [E05B 65/10, 65/02]

The technique disclosed in Patent Document 1 has a cam structure that slides by the rotation of the rotating plate, so the movement is not smooth and there is a possibility of malfunction.

Therefore, the main object of this invention is to provide a novel delivery box.

Another object of the present invention is to provide a delivery box that has a simple structure and can be smoothly and easily unlocked from the inside.

In order to solve the above problems, the present invention employs the following configuration. Note that the reference numerals and supplementary explanations in parentheses indicate the correspondence with the embodiments described to aid understanding of the present invention, and do not limit the present invention in any way.

The first invention provides a casing with one side open, a door attached to the casing to open and close the opening, and a lock that is attached to the door and locks the door to the casing with the opening closed. A delivery box comprising: a housing; a latch that is biased by a spring and engages the housing at a first position protruding from the housing; an operating part for moving the latch into the housing and moving the latch to the second position; and a shaft extending in a direction parallel to the inner surface of the door; This delivery box includes an unlocking lever that can be rotated in a direction towards and away from the user, and a rotating member that rotates in a plane orthogonal to an axis in conjunction with the rotation of the unlocking lever to move an operating section.

In the first invention, the delivery box (10: a reference numeral illustrating a corresponding part in the embodiments. However, this does not mean limitation. The same applies hereinafter) has a casing (12) with one side open. A door (34) is attached to the housing to open and close the opening. A lock (40) is attached to this door to lock the door (34) to the casing (12) with the opening closed. The lock (40) is movable within the housing (44) and the latch (42) which is biased by a spring and engages the housing (12) in a first position protruding from the housing (44). , and an operating portion (56) for retracting the latch (42) into the housing (44) and moving it to the second position against the bias of the spring. Therefore, when the operating section (56) is moved from inside the housing, the latch that moves together with the operating section (56) is retracted into the second position. The delivery box (10) is provided with a shaft (82) extending in a direction parallel to the inner surface of the door (34), and the base end of an unlocking lever (76) is rotatably supported on this shaft (82). be done. The free end of the unlocking lever (76) can be rotated in the direction toward and away from the inner surface of the door, and in conjunction with the rotation of the unlocking lever (76), the rotating member (88, 98) rotates around the shaft ( 82) to move the operating section (56).

According to the first invention, the operating section is moved by the rotating member (88, 98) that rotates in conjunction with the unlocking lever (76), so that the lock can be easily unlocked.

A second invention is a delivery box depending on the first invention, wherein the rotating member includes first and second L-shaped pieces each having a first side and a second side, and the rotating member includes first and second L-shaped pieces, each having a first side and a second side. The L-shaped piece rotates in a plane in conjunction with the rotation of the unlocking lever, and the second side of the first L-shaped piece transmits the rotation to the second L-shaped piece. The second L-shaped piece engages with the first side of the second L-shaped piece, and the second side of the second L-shaped piece engages with the operating section.

In the second invention, the rotating member (88, 98) includes first and second L-shaped pieces (88, 98), and the first and second L-shaped pieces (88, 98) each have a second L-shaped piece (88, 98). It has one side (88A, 98A) and a second side (88B, 98B). The first L-shaped piece (88) rotates within the plane in conjunction with the rotation of the unlocking lever (76). Since the second side (88B) of the first L-shaped piece (88) is engaged with the first side (98A) of the second L-shaped piece (98), the first L-shaped piece (88) is transmitted to the second L-shaped piece (98). In response, the second L-shaped piece (98) rotates in the same plane, and its second side (98B) engages with the operating portion (76) to move the operating portion (56); A latch (42) integrally formed with this operating portion (56) is retracted to unlock the lock (40).

According to the second invention, since it is only necessary to provide the first and second L-shaped pieces that interlock with the unlocking lever, the structure is simple and the possibility of failure can be suppressed.

A third invention is a delivery box according to the first or second invention, further comprising an angle for attaching a lock to the door, and the shaft is supported by the angle.

In the third invention, the angle (58) is not only used to attach the lock (40) to the door (34), but also to provide the shaft (82) in a direction parallel to the inner surface of the door. Ru.

According to the third invention, since the lock and the shaft can be installed at the same angle, it is easy to install the lock and the shaft.

A fourth invention is a delivery box according to the third invention, wherein the shaft is supported by the angle as a rotating shaft, the base end of the unlocking lever is fixed to the rotating shaft, and the first L-shaped The piece is fixed to the rotating shaft and moves in conjunction with the rotation of the unlocking lever.

In the fourth invention, the shaft (82) is supported by the angle (58) as a rotating shaft, and the base end of the unlocking lever (76) is fixed to the rotating shaft (82). Furthermore, a first L-shaped piece (88) is fixed to the rotating shaft (82). Therefore, the first L-shaped piece (88) rotates in conjunction with the rotation of the unlocking lever (76), and the operating section (76) is moved by the second L-shaped piece (98). .

In the fourth invention, since the unlocking lever and the first L-shaped piece are fixed to the rotating shaft, the first L-shaped piece is reliably interlocked with the unlocking lever.

According to this invention, when the unlocking lever is pressed, the operating section is moved by the interlocking rotating member to retract the latch, so that the lock can be reliably unlocked.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

Referring to FIG. 1, a delivery box 10 according to an embodiment of the present invention is installed in, for example, a detached house, and stores items to be delivered in a lockable manner, and is also called a delivery locker or the like. .

In this embodiment, the delivery box 10 includes a vertically elongated casing 12 with a front opening, and this casing 12 has three side plates 14 including a rear surface (not visible), a bottom plate 16, and a top plate 18, which are made by welding or welding, for example. Can be assembled by joining with screws.

The inside of the housing 12 is divided into upper and lower housing sections 22 and 24 by a partition plate 20 . The front opening of the upper housing part 22 is opened and closed by an upper door 28. That is, the upper door 28 is attached to the front part of the right side plate 14 by a hinge 30, and can be opened and closed by the hinge 30. A locking mechanism 38 for locking the upper door 28 to the left side plate 14 of the housing 12 is provided at the left end of the upper door 28 (on the opposite side of the hinge 30).

The front opening of the lower housing portion 24 is opened and closed by a lower door 34. That is, the lower door 34 is attached to the front part of the right side plate 14 by a hinge 36, and can be opened and closed by the hinge 36. A locking mechanism 38 for locking the lower door 34 to the left side plate 14 of the housing 12 is provided at the left end of the lower door 34 (opposite the hinge 36).

Since the upper accommodating part 22 is located at a high position and is small, there is almost no risk of children or the like getting into it. An embodiment aimed at preventing the risk of entrapment of children and the like is directed to the lower door 34 of the lower housing 24 and its locking mechanism 38.

The locking mechanism 38 of the lower door 34 attaches a lock 40 having a latch 42 shown in FIG. 2 to the lower door 34 using an angle 58 shown in FIG.

As the lock 40 in this embodiment, a latch lock "CP-578" manufactured by Takigen Manufacturing Co., Ltd. is used as an example. However, the lock that can be used in this embodiment is not limited to this specific lock, and is used to move the latch 42 from the inside to its retracted position (second position), which corresponds to the operating section 56 described later. It is possible to use a lock that has the following components.

A detailed description of the internal structure is omitted because it is well known, but as shown in FIG. 2, the lock 40 includes a housing 44 that is elongated in the vertical direction (horizontal direction during use). A front portion 46 is provided on the front surface of this housing 44 . The rear surface of the housing 44 (opposite the front surface 46) is provided with a threaded hole 48 forming an internal thread for attaching the lock 40 to the lower door 34 using an angle 58. Since the external dimensions of the front part 46 are set larger than those of the housing 44, when the lock 40 is attached to the lower door 34, it is fixed by this front part 46.

The latch 42 is biased within the housing 44 by a spring (not shown) and normally projects from the lateral front end of the housing 44. As is well known, when the latch 42 is pressed by a spring and protrudes (in the first position), the latch 42 is formed in an engagement hole or a latch hole ( (not shown) to maintain the closed state of the lower door 34.

A knob 50 provided on the front portion 46 can be rotated into two positions: a locked position or an open position. When the knob 50 is set to the lock position and the lower door 34 is closed, an auto-lock state (locked state) in which the latch 42 is engaged with the engagement hole is achieved.

In this state, by turning the knob 50 to the open position, inserting a key (not shown) into the keyhole 52 provided on the front and turning it, the latch 42 can be retracted against the spring (not shown). the second position. That is, when the key inserted into the keyhole 52 is turned, the latch 42 can be returned to the second position (the non-protruding (recessed) position) and unlocked.

However, a person trapped in the lower accommodation section 24 (FIG. 1) cannot use the key from outside or turn the knob 50, and cannot escape from the locked state.

On the other hand, a thumb turn knob 54 that can switch between the lock position and the open position described above is provided to protrude inward (to the right in FIG. 2B) from the housing 44 of the lock 40. Further, an operating section 56, which is an emergency unlocking mechanism, is provided so as to protrude inwardly from the housing 44. This operation part 56 is formed integrally with the latch 42, and when it is moved, the latch 42 can be forcibly moved from the first position to the second position in conjunction with the operation part 56. Therefore, when the thumb turn knob 54 is in the open position, the lock can be unlocked from the inside by operating and moving the operating portion 56 from the inside.

However, if the person trapped in the lower accommodation section 24 is a child, such as an infant, it will be almost impossible to operate the operating section 56, and the person will remain trapped. In addition, when the lower door 34 is closed, the inside of the lower accommodation section 24 is almost dark, and even if the trapped person is an adult, it is impossible to open the lower door 34 by operating the operating section 56. Close to.

Therefore, in this embodiment, a delivery box 10 is provided which has a locking mechanism 38 that allows even an infant or the like to easily break out of such a locked-in state.

As shown in FIG. 3, the mounting angle 58 for attaching the lock 40 to the lower door 34 is formed by press-molding, for example, a single iron plate, and is formed into a "convex" shape in cross section as a whole.

The angle 58 has opposing plate portions 60 facing each other with an inner dimension AA corresponding to the width A of the housing 44 of the lock 40 (FIG. 2(C)). The opposing plate portions 60 are each bent inward by 90 degrees at a height BB that is higher than the thickness B of the lock 40 (FIG. 2(B)) to form a flat plate portion 62 of a constant width that continues to the opposing plate portion 60. Ru. Lever mounting plate parts 64 each having a predetermined height are formed by further bending upward by 90 degrees from the flat plate part 62 . The lever mounting plate part 64 is connected by a cover plate part 66.

Two through holes 68 for attaching locks are formed in both flat plate portions 62, respectively. Further, in the lever mounting plate portion 64, a first shaft support hole 70 is formed at a corresponding position on each one end side, and a second shaft support hole 72 is formed at a corresponding position on each other end side. be done. However, as shown in FIG. 3, the first shaft support hole 70 is formed at a slightly lower position than the second shaft support hole 72 (closer to the flat plate part 62).

Using such a lock 40, angle 58, and unlocking lever 76 (described later), a locking mechanism 38 is constructed as shown in FIGS. 4 to 7.

Insert the housing 44 of the lock 40 from the front side of the lower door 34 into the horizontally long mounting hole (not shown) formed in the lower door 34 partially shown in FIG. insert.

Then, as shown in FIGS. 4 and 6-7, the angle 58 is placed over the housing 44 of the lock 40 so that the opposing plate portions 60 of the angle 58 sandwich both sides of the housing 44. Screws 74 are inserted into the screw holes 48 formed in the rear surface of the housing 44 of the lock 40 through the through holes 68 formed in the flat plate portion 62 and tightened. The lock 40 is then fixed to the flat plate portion 62 of the angle 58. On the other hand, as shown in FIGS. 6-7, the lower end 60a of the opposing plate 60 comes into contact with the back surface of the lower door 34. The lock 40 is fixedly attached to the lower door 34 by sandwiching the lower door 34 between the front part 46 and the opposing plate part 60 in this manner. Thereafter, the unlocking lever 76 and the two L-shaped pieces 88 and 98 are attached to the angle 58.

The unlocking lever 76 is formed, for example, by pressing a single iron plate, and has a flat plate portion 78. Continuing from the flat plate part 78, two side plate parts 80 which are bent at 90 degrees from both sides of the flat plate part 78 are formed on the tip side of the flat plate part 78 (the side of the latch 42 of the lock 40). In the side plate portion 80, through holes 84 through which the rotating shaft 82 is inserted are formed at corresponding positions. The opening 86 formed in the flat plate portion 78 is an opening for operating the thumb turn knob 54.

When attaching such an unlocking lever 76 to the lever mounting plate 64 of the angle 58, first pass the tip of the rotating shaft 82 through the through hole 84 of the side plate 80 above the unlocking lever 76 (in FIG. 4). Next, the rotating shaft 82 is inserted through the first shaft support hole 70 of the lever mounting plate section 64 on the upper side (in FIG. 4). The tip of the rotating shaft 82 reaches the middle (between) the two lever mounting plate parts 64. The rotating shaft 82 is inserted into the through hole 90 of the first L-shaped piece 88 between the two lever mounting plate parts 64 . Then, cover the rotating shaft 82 with spacers 92A and 92B for position adjustment, insert the tip of the rotating shaft 82 into the first shaft support hole 70 of the lower lever mounting plate 64, and then insert the lower end of the unlocking lever 76. It is inserted into the through hole 84 of the side plate part 80 of. In this state, an E-ring 94 is fitted to the tip of the rotating shaft 82 to fix the rotating shaft 82 so that it does not come off.

Furthermore, in FIG. 4, the fixed shaft 96 is inserted into the second shaft support hole 72 of the upper lever mounting plate portion 64 from its tip. The tip of the fixed shaft 96 reaches the middle (between) the two lever mounting plate parts 64. The tip of the fixed shaft 96 is inserted into the through hole 100 of the second L-shaped piece 98 between the two lever mounting plate parts 64. Then, the fixed shaft 96 is covered with a spacer 92A for position adjustment, and the tip of the fixed shaft 96 is inserted into the second shaft support hole 72 of the lower lever mounting plate portion 64. In this state, an E-ring 94 is fitted to the tip of the rotating shaft 82 to fix the rotating shaft 82 so that it does not come off.

In this way, the rotating shaft 82 is supported using the first shaft support hole 70, and the first L-shaped piece 88 and the unlocking lever 76 are attached to rotate integrally with the rotating shaft 82. . The fixed shaft 96 is supported using the second shaft support hole 72, and the fixed shaft 96 rotatably supports the second L-shaped piece 98.

According to this embodiment, the angle 58 is used not only for attaching the lock 40 to the lower door 34, but also for locating the rotating shaft 82 and the fixed shaft 96 in a direction parallel to the inner surface of the lower door 34. Since it is used, the number of parts is small, the structure is simple, and each installation process is simple.

As can be clearly seen from FIG. 4, the through hole 84 formed in the side plate portion 80 of the unlocking lever 76 is formed in the shape of a "D" with a portion of a circle cut off. Accordingly, the rotating shaft 82 is also formed in a "D" shape in cross section, as shown by the dotted line in FIG. Furthermore, the through hole 90 of the first L-shape 88 is also shaped like a "D". Therefore, the unlocking lever 76, the rotating shaft 82, and the first L-shaped piece 88 rotate integrally without idle rotation. That is, since the unlocking lever 76 and the first L-shaped piece 88 are fixed to the rotating shaft 82, the first L-shaped piece 88 is reliably interlocked with the unlocking lever 76.

On the other hand, the fixed shaft 96 has a circular cross section, and the through hole 100 of the second L-shaped piece 98 also has a circular shape, so that the second L-shaped piece 98 rotates on the fixed shaft 96.

FIG. 5 further illustrates the positional relationship between the two L-shaped pieces 88 and 98 provided between the two lever mounting plate parts 64.

That is, the rotating shaft 82 is inserted into the through hole 90 of the first L-shaped piece 88 between the lever mounting plate portions 64 . The first L-shaped piece 88 includes a first side 88A and a second side 88B connected at a substantially right angle to the first side 88A. Since the rotating shaft 82 is inserted through the through hole 90 provided in the connecting portion of the first L-shaped piece 88, as the rotating shaft 82 integrated with the unlocking lever 76 rotates, the surface perpendicular to the rotating shaft 82 is rotated. It rotates or pivots inward, that is, in a plane parallel to the inner surface of the lower door 34.

A rotating shaft 82 is inserted through the second shaft support hole 72 of the lever mounting plate portion 64 of the angle 58, and a second L-shaped piece 98 is fixed to the rotating shaft 82. The second L-shaped piece 98 is provided at a position corresponding to the first L-shaped piece 88 in the axial direction of the fixed shaft 96 . Spacers 92A and 92B are used for such position adjustment.

The second L-shaped piece 98 includes a first side 98A and a second side 98B connected at a substantially right angle to the first side 98A. The second L-shaped piece 98 of the fixed shaft 96 is inserted through the through hole 100 of the connecting portion thereof. However, the second L-shaped piece 98 is provided rotatably with respect to the fixed shaft 96.

In particular, as can be clearly seen from FIG. 8, the second side 98B of the second L-shaped piece 98 engages with the operating portion 56 of the lock 40 on the outside of the operating portion 56, that is, on the side from which the latch 42 protrudes. Although the second side 88B of the first L-shaped piece 88 and the first side 98A of the second L-shaped piece 98 are separated in FIG. 8, they are actually close to each other as shown in FIG. ing.

In the locking mechanism 38 configured as described above, in a normal state, that is, when the knob 50 and the thumbturn knob 54 are in the open position and the latch 42 is protruded to the first position, the locking mechanism 38 is operated as shown in FIG. 9(A). As such, the unlock lever 76 is parallel to the inner surface of the lower door 34. Therefore, both the second side 88B and the first side 98A of the first L-shaped piece 88 and the second L-shaped piece 98 are parallel to the inner surface of the lower door 34. Therefore, the latch 42 is in the first position and inserted into the engagement hole (not shown) of the housing 12 without the operation part 56 moving. Therefore, even if the lower door 34 is pushed outward, it will not open.

As shown in FIG. 9(B), when the free end of the unlocking lever 76 is pushed and rotated in the direction of arrow C, the rotating shaft 82 to which the base end is fixed rotates in the direction of arrow D. The first L-shaped piece 88 fixed to the rotating shaft 82 also rotates in the direction of arrow D within a plane parallel to the inner surface of the lower door 34. Therefore, the first side 98A of the second L-shaped piece 98 that is engaged with the second side 88B of the first L-shaped piece 88 is pushed by the second side 88B, so that the second L-shaped piece 98 rotates in the direction of arrow E within the same plane in which the first L-shaped piece 88 rotates.

As a result, the operating portion 56 engaged with the second side 98B of the second L-shaped piece 98 is pushed by the displacement of the second side 98B and is moved in the direction of arrow F. Therefore, the latch 42 that moves integrally with the operating portion 56 is retracted into the second position. Therefore, when the latch 42 and the engagement hole are disengaged and the lower door 34 is pushed from inside, it can be opened as is. Therefore, even if a person such as a child is trapped in the lower accommodation section 24 (FIG. 1), they can quickly escape from the situation.

As described above, according to this embodiment, the lock can be unlocked by simply pushing the free end of the unlocking lever 76 in the direction of the lower door 34, so even a child can intuitively push the unlocking lever 76 in that direction to unlock the lower door 34. can be opened.

Furthermore, since it is only necessary to provide the first and second L-shaped pieces 88 and 98 that interlock with the unlocking lever 76, the structure is simple and the possibility of failure can be suppressed.

As mentioned above, since the operating part 56 of the lock 40 is pushed by the second side 98B of the second L-shaped piece 98 and moves in the direction of arrow F parallel to the inner surface of the lower door 34, if the operating part 56 If the moving stroke of the operating portion 56 is long, the tip of the operating portion 56 may interfere with the first L-shaped piece 88. In that case, as shown in FIG. 9(A), it is conceivable to form a gap G between the housing 44 of the lock 40 and the first L-shaped piece 88, which is large enough to allow the operation part 56 to pass through. In this way, the movement of the moving operating section 56 will not be hindered by the first L-shaped piece 88.

In order to form this gap G, as explained in FIG. 3, the heights (distances from the lower door 34) of the first shaft support hole 70 and the second shaft support hole 72 are different. That is, since the second shaft support hole 72 is farther from the lower door 34 than the first shaft support hole 70, the gap G is formed by this difference.

Furthermore, in the locking mechanism 38 of this embodiment, when the free end of the unlocking lever 76 is pushed in the direction of the lower door 34, the first and Since the second L-shaped pieces 88 and 98 rotate in the same plane and move the latch 42 to the second position as they rotate, the latch 42 is moved more reliably than when using a sliding cam as in the background art. The latch 42 can be moved to the unlocked position (second position).

In the above-described embodiment, the shaft 82 that supports the unlocking lever 76 and the first L-shaped piece 88 is used as the rotating shaft, and the unlocking lever 76 and the first L-shaped piece 88 are fixed to the rotating shaft 82. When the unlocking lever 76 is pushed, the rotating shaft 82 rotates, and the first L-shaped piece 88 rotates in conjunction with the rotating shaft 82. However, the rotating shaft 82 may be a fixed shaft, and the fixed shaft may rotatably support the unlocking lever 76 and the first L-shaped piece 88. In this case, for example, when the first side 88A of the first L-shaped piece 88 is engaged with the base end of the unlocking lever 76 and the unlocking lever 76 is pressed, the first L-shaped piece 88 is The rotation may be made in the direction of arrow E as described above.

Furthermore, in the above-described embodiment, two L-shaped pieces 88 and 84 were used as the rotating members that interlock with the unlocking lever 76, but the structure is not limited to this. For example, the height of the lever mounting plate portion 64 of the angle 58 may be increased, a disk (semi-circular plate) with a notch formed on the outer periphery may be adopted, and the notch may be engaged with the operating portion 56. Possible variations include:
