[0002]
[Prior art]
A conventional puller for a storage cabinet with double doors is provided with a puller operated with the left hand on the left door and a puller operated with the right hand on the right door in the vicinity of the fitting portion of the left and right doors. . In such a storage, when a person with one hand is incapable of opening and closing the door on the side opposite to the dominant hand, it is necessary to place the hand on the pulling hand with the palm facing the opposite side. In addition, when a storage with double doors is stacked and installed on the upper stage, it may be difficult for a person with a short height to open and close the door of the storage.
[0003]
On the other hand, for example, when stacking a storage with a double door on the upper stage of a horizontally long drawer-type storage, the drawer puller of the drawer-type storage is in the center of the front plate of the drawer developed by the applicant of the present application. A storage box with a vertical puller that extends near the upper and lower ends of the drawer, and the puller of each drawer is connected in a straight line and can be pulled out with one hand. In this case, the puller of the lower storage and the puller of the upper storage are different, and the appearance is unbalanced and a sense of incongruity is felt. In such a case, a unified design aesthetic can be created by arranging the puller of the storage with the double door of the upper tier in a form that is connected to the puller of the lower tier in a straight line perpendicular to the center. . In this case, the puller needs to have a function of releasing the engagement of the latch mechanisms provided above and below the door in conjunction with the pulling operation.
[0004]
[Problems to be solved by the invention]
In view of the above situation, the present invention intends to solve the problem that a double door puller provided in furniture or a passage is covered with a vertical puller that covers the entire fitting portion of the door and creates a design aesthetic. In addition, it can be operated by placing a hand at an appropriate height according to the height of the person and the height of the door, can be easily opened and closed with either the left or right hand, and can be operated regardless of the position where the hand is placed on the puller. It is another object of the present invention to provide a completely new form of a pulling mechanism that reliably operates the latch mechanism. Another problem to be solved by the present invention is that the door puller on the side having the puller and the latch mechanism described above can be easily assembled with a structure that restricts the opening of the other door, and the manufacturing cost is reduced. Still another object of the present invention is to provide a pulling mechanism in which the latch mechanisms above and below the door operate in synchronism with each other regardless of the position where the vertical pulling hand is engaged.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the double door puller mechanism according to the present invention is provided in the vicinity of the upper and lower ends of the double door, which is supported by the frame body so that the left and right side ends can be rotated. A pair of horizontal pull levers rotatably supported at the intermediate portion and a front end of the fitting portion and a front gap between the front and rear door levers are connected to each other with a gap between them. A vertical puller and a lock state between the door and the frame body are provided in conjunction with the rotation of the puller lever at the time of opening the door provided inside or on the back side of the door to which the puller is attached.

[0015]
The puller 6 includes a vertical bar-shaped intermediate member 6a and end members 7 and 7 which are attached to both ends of the intermediate member 6a after the pull lever 8 is attached to both ends of the intermediate member 6a. The intermediate member 6a is formed so that the horizontal cross-sectional shape is a substantially isosceles triangle having the front end 6b as a base and the rear end surfaces 6b and 6b as left and right pieces.
[0016]
Further, in the portion where the pull handle 6 of each of the doors 2 and 2a is located, there are an inclined side surface 4a inclined rearward in the vicinity of the upper and lower ends, and a door surface extending from the middle of the inclined side surface 4a to the mating portion 2d. Recessed portions (concave portions) 4 and 4 formed by a bottom surface 4b formed in parallel with the plate 2b are provided. The puller 6 is attached to the door 2 in such a relationship that part of the rear end side is submerged in the retracted portion 4.
[0017]
Further, at the rear ends of the upper and lower end members 7, 7 of the pull handle 6, the latch mechanism contacts the front surfaces of the upper and lower ends of the doors 2, 2 a on both sides when the door 2 is locked to the housing 1 a. It has an abutting end face 7a in contact therewith. The contact end surface 7a may be formed so as to contact the bottom surfaces 4b and 4b of the retracted portions 4 and 4 of the doors 2 and 2a on both sides, although not shown.
[0018]
Each of the doors 2 and 2a has a substantially symmetrical structure. As shown in FIG. 5, the front plates 2b of the doors 2 and 2a are formed with the above-described retracted portion 4 on the mating portion 2d side of the rectangular plate member, and the right and left edge portions of the plate member are folded back. The U-shaped bent part is formed, while the upper and lower end edges are folded in a U-shape on the back side, the edge is further folded toward the housing 1a side, and the edge is directed toward the front side. And bent into a shape having rigidity at these bent portions. Further, the back plate 2c to be overlapped near the mating portion 2d on the back side of the front plate 2b is formed by folding each end edge portion of the rectangular plate member to the front plate 2b side as shown in FIGS. The mating portion 2d of the front plate 2b and the end portions thereof are formed so as to overlap each other. When the back plate 2c and the front plate 2b are overlapped with each other, the spacer 3 that is inserted into the intermediate portion in the width direction of the internal space formed by the two members to reinforce the both sides of the vertically long rectangular plate member is perpendicular to the front plate side. It is a member that is woven and has its edges folded at right angles outward. The doors 2 and 2a are formed by overlapping these members 2b, 2c and 3 as shown in FIGS.
[0019]
It should be noted that the upper and lower corners on the mating part 2d side of the doors 2 and 2a are respectively provided with notches for attaching the pull support members 10 and 10a, and the center side of the door 2 slightly from the end of the mating part 2d. A notch for mounting the shaft support member 16 and projecting the tip of the latching tool 25 toward the housing 1b is provided at a location that is spaced apart from each other and faces the upper and lower flanges 1b of the housing 1a.
[0020]
As shown in FIG. 2 and FIG. 3, a latch tool insertion opening 1c is formed at a position facing the notch for mounting the shaft support member 16 at the front end of the upper and lower flanges 1b of the housing 1a. A latch receiving tool 27 is attached and fixed to the latch tool insertion opening 1c. The latch receiving device 27 is a frame having a through-hole at the center, and has a shape in which the outer periphery is fitted to the inner edge of the latch device insertion port 1c, and a latching claw that abuts on the back surface of the latch device insertion port 1c. This is a structure that can be locked and fixed to the collar portion 1b with the locking claw.
[0021]
Next, a more detailed structure of each component of the pulling mechanism 5 will be described below. First, the shaft support member 16 and the puller support members 10 and 10a will not be described in detail, but as shown in FIG. 5, they are pushed in from the notches of the front plate 2b of the doors 2 and 2a, respectively. 3 and the back plate 2c are formed into a shape having a support groove and a stepped support portion.
[0022]
Next, the vertical shaft 15 has a square horizontal cross section, a locking hole (not shown) for locking one end of the biasing spring 20 in the middle, and the end of the shaft 15 near the upper and lower ends. A supporting and fixing part (not shown) of the driven lever 18 inserted from the part, a supporting and fixing part of the latch tool 25 at both ends, and a supporting part for rotatably supporting the bearing hole 17 of the shaft support member 16 Respectively. The driven lever 18 is a member provided with a square insertion hole for restricting the relative rotation by allowing the shaft 15 to vertically penetrate one end of a U-shaped groove-shaped member as viewed from the front end. The spring support frame 21 is a frame body having an insertion hole through which the shaft 15 is inserted, and a locking portion 22 protrudes from a side surface, and a locking claw 22a is provided on the top and bottom surfaces of the locking portion 22. The spring support frame 21 can be inserted into a locking hole 23 formed on the side surface of the spacer 3 and can be locked and held by a locking claw 22a. The biasing spring 20 is a coiled spring and is housed and held inside the spring support frame 21, and one end thereof is locked to the shaft 15 and the other end is locked to the spring support frame 21. The latch tool 25 is a member that has a rectangular insertion hole for allowing the shaft 15 to penetrate vertically and restrict relative rotation at the base end, and a latch claw 26 that protrudes in a hook shape toward the side at the tip. is there. The shaft support member 16 includes a support portion that supports the bent portions of the upper and lower end portions of the front plate 2b of the door 2, an internal space that opens to the rear side surface, and a bearing hole 17 that supports the end portion of the shaft 15. I have.
[0023]
The procedure for incorporating each member into the door 2 is as follows. First, the urging spring 20 and the spring support portion 21 are mounted on the shaft 15, and then the driven lever 18 is mounted and fixedly supported. Then, the rear end of the latch device 25 is inserted into the inner space of the shaft support member 16 from the opening, the shaft mounting portion of the latch device 25 is made to coincide with the bearing hole 17, and the end portion of the shaft 15 is made the bearing of the shaft support member 16. The latch tool 25 is attached and fixed to the end of the shaft 15 by being inserted toward the hole 17. Then, the shaft support members 16 and 16 of the assembly of the shaft 15 to which the biasing spring 20, the spring support portion 21, the driven lever 18, the latch tool 25, and the shaft support member 16 are attached are mounted on the notch portion of the door 2.
[0024]
The pull lever 8 is a horizontal plate-like member having a screw hole formed through the tip. The end of the intermediate member 6 a of the pull handle 6 is brought into contact with the screw hole of the pull lever 8 and fixed with screws 9 and 9. Similarly, the lower end side of the intermediate member 6 a of the puller 6 is fixed to the puller lever 8 with screws 9 and 9. Then, the end members 7 and 7 are attached and fixed to the levers 8 and 8 at the upper and lower ends of the middle member 6a of the upper and lower pullers, and the puller 6 is assembled. Then, the pull lever 8 of the assembled pull handle 6 is inserted into the pull support member 10, and the pin 11 is attached to the through hole 8 a of the pull lever 8 to limit the pull support member 10. Supports relative rotation. Then, with the puller support member 10 and the puller 6 combined, the puller support members 10 and 10 are mounted in the cutouts in the upper and lower corners of the mating portion side of the door front plate 2b.
[0025]
Finally, from the back surface of the front plate 2b of the door 2, the shaft support member 16 is pressed by the spacer 3, the locking portion 22 of the spring support frame 21 is inserted into the locking hole 23, and the locking claw 22a is engaged. Then, the door 2 is assembled as a unit by overlapping the back plate 2c. Since the left door 2a does not have the pull handle 6, the shaft 15 and the shaft support member 16 and the like are not mounted, and the pull handle has a form that is symmetrical to the pull support member 10 and does not have the support portion of the pull lever 8. The support member 10a is mounted, the spacers 3 are overlapped in the same manner as described above, and the back plate 2c is overlapped and integrated to assemble the door 2a.
[0026]
Next, the operation of the pulling mechanism 5 having the above configuration will be described. When the doors 2 and 2a are closed, the latch claw of the latching tool 25 of the pulling mechanism 5 engages with the latch receiving tool 27 to restrict the opening of the door 2, and the end members 7 at the upper and lower ends of the pulling handle 6 are used. , 7 The abutting end surfaces 7a, 7a at the rear end are the front surfaces of the upper and lower ends of the doors 2, 2a (or, although not shown in the figure, they may abut against the bottom surfaces 4b, 4b of the retreating parts 4, 4 of the doors 2, 2a) Abut. Therefore, the opening of the door 2 a is restricted by a latch mechanism that operates in conjunction with the puller 6 of the door 2. In this state, when an appropriate portion of the intermediate member 6a of the pull handle 6 is pulled forward with either the left or right hand, the pull levers 8 and 8 are rotated forward and come into contact with the rear ends of the pull levers 8 and 8. The driven lever 18 is pushed backward to rotate, and the shaft 15 rotates clockwise as viewed from the upper end. As a result, the latch device 25 rotates to the right, the engagement between the latch claw 26 and the latch receiver 27 is released, and the door 2 is opened forward. Then, the left door 2a can be opened.
[0027]
Since the upper and lower latching tools 25, 25 are fixed to both ends of the single shaft 15 and rotate in conjunction with each other at the same angle, the upper and lower latching tools 25, 25 The engagement lock between the latch 25 and the latch receivers 27 is released. Further, the rear end surfaces 6c and 6c of the pull handle 6 are positioned with an appropriate gap between the inclined side surfaces 4a and 4a and the bottom surfaces 4b and 4b of the retracted portions 4 and 4 of the doors 2 and 2a. It is possible to draw the hand without any trouble from either the left or right side or the right or left hand.
[0028]
When closing the door, when the left door 2a is closed and the right door 2 is closed, the latch devices 25 and 25 enter the latch receivers 27 and 27, and the latch claws 26 and 26 are latch latches 27. 27, the door 2 is locked, and the door 2a is also restricted from opening by the end members 7 and 7 of the pull handle 6 coming into contact with each other.
[0029]
Next, although not shown, an embodiment having a different form from the above-described embodiment will be described below. First, for the puller 6, the intermediate member 6a may have an appropriate shape instead of the isosceles triangle in the horizontal section. Further, the doors 2 and 2a may be flat front surfaces without providing the retracting portions 4 and 4 at the position of the pulling handle. In that case, an appropriate gap is formed between the front surfaces of both doors where the intermediate member of the puller is located and the intermediate member of the puller. However, as described above, if both doors are provided with receding parts and a part of the rear end side of the intermediate handle is submerged in the receding parts, the protrusion of the pulling doors in front of the doors is less likely to interfere. It is convenient because it creates a beautiful aesthetic.
[0030]
Unlike the system in which the biasing spring 20 is provided on the shaft 15 as described above, the latch mechanism may support the driven lever and the latching tool individually and provide the biasing springs respectively. The latch tool may be rotated by extending the rear end and bringing the rear end of the pull lever directly into contact with the rear end. However, in the above-described embodiment, the assembly can be easily performed and the latch mechanism can be operated in a vertical synchronous manner irrespective of the position where the hand is put on the puller. I can say that.
[0031]
Next, FIG. 6 shows a storage box 1 with double doors shown in FIG. 1 and a puller 32 having the same shape as the puller 6 of the puller mechanism 5 provided in the door 2. The external appearance of the drawer-type storage 30 attached so as to be aligned in a vertical straight line at the center of each drawer 31 of the type storage 30 is shown in the state of being stacked up and down. A puller 32 having the same shape as the puller 6 of the pulling mechanism for double doors according to the present invention is provided vertically in the center of the drawer of the pull-out storage 30 in the form as shown in FIG. When the storage 30 is combined with the storage 1 and stacked up and down, the upper and lower storage handles are arranged in a straight line in the center, and the design of the upper and lower pullers is harmonized, creating a new design aesthetic. convenient.
[0032]
Although not shown and described, a pulling mechanism similar to the pulling mechanism 5 described above according to the present invention can be provided in the same manner as described above in the double doors of the passage and the entrance / exit. In that case, as in the description of the pulling mechanism 5 of the door 2 of the storage 1 described above, the operation effect can be obtained that the operation can be easily performed with either the left or right hand, and the position in the height direction for gripping the pulling hand is not limited. And new design aesthetics are created.
[0033]
【The invention's effect】
In the double door pulling mechanism according to the first aspect of the present invention as described above, a pair of pulling mechanisms in which the intermediate portion is horizontally supported in the vicinity of the upper and lower ends near the fitting portion of one door of the double door. A hand lever is provided, and a vertical puller that connects the tips of the upper and lower puller levers is provided in front of the door fitting part so that there is a gap between the front of the door and the door can be opened with the puller. A latch mechanism that releases the locked state of the door and the frame body to which the door is attached in conjunction with the rotation of the pull lever when the lever is engaged, and biasing means for biasing the latch mechanism in the latch claw engagement direction Therefore, according to the height of the person, it can be operated by placing the hand at an appropriate height of the puller, and can be opened and closed by placing the hand on the puller from either the left or right direction. And since almost the entire fitting part of the door is covered with a pulling handle, there is an effect such as the creation of a new design aesthetic. Further, the part where the pull handle on the front of the double door is located is inclined rearward over the vicinity of the upper and lower ends to form a retreat part, and a part of the rear end side of the pull handle is submerged in the retreat part. Therefore, the amount of protrusion from the front face of the door of the puller is reduced, and there is an effect that the design is not disturbed and aesthetics are created.
[0034]
In the double door puller mechanism according to the second aspect of the invention, the intermediate portion excluding the upper and lower ends of the puller is formed so that the horizontal cross section is a substantially isosceles triangle with the front end as the base, and the puller Since the upper and lower ends are fixed to the tip of the pull lever respectively, it is easy to insert a hand into the gap between the door and the pull handle, and if the horizontal cross section is an isosceles triangle, the structure is lightweight and stable in strength. In addition, there are few effects such as a bulge forward, an excellent function, and a beautiful design.
[0036]
According to a third aspect of the invention, the double door puller mechanism is respectively applied to the upper and lower ends of the puller and to the front surface of the doors on both sides or the front surface of the retracted portion when the latch mechanism locks the door to the frame. Since the contact end surface is provided, there is an effect that the handle of the latched door is brought into contact with the upper and lower ends in the vicinity of the mating portion of the mating door to restrict the opening of the door. Further, this eliminates the need to provide a pulling mechanism and a latch mechanism on both doors, so that the manufacturing cost can be reduced.
[0037]
In the double door puller mechanism according to the fourth aspect of the present invention, a vertical rotating shaft is provided in the door near the fulcrum of the puller lever or on the rear surface of the door, and the tip of the puller lever is located at both ends of the shaft. A pair of driven levers that rotate in contact with the end portions are fixed, and latch claws that engage with latch receivers at the upper and lower front end portions of the frame body that supports the door are fixed to both ends of the shaft, and Since the latch mechanism is provided with an urging spring for urging the latch pawl in the engaging direction with respect to the latch receiver on the shaft, the upper and lower latch claws are interlocked with each other and the position where the puller is pulled forward is determined. Even if the vertical position of the pulling lever is not the same, that is, the rotation angle of the upper and lower pulling levers does not match, the upper and lower latching pawls rotate at the same angle, and the urging force is applied to each of the upper and lower latching claws. Acts evenly and performs stable synchronous operation There is a use effect.
