However, the present invention is not limited to the attached drawings and includes all the embodiments that satisfy the requirements described in the claims. The pulling door with a latch for sliding doors according to the present invention is mainly used by being attached to the front side end of a sliding door that is movably arranged in a door frame of an opening of a bookcase, a product display rack, a storage, or the like. It is used as a self-latching means of the sliding door to prevent recoil opening when the sliding door is closed or to prevent the fall of stored items during an earthquake, etc., but here it is attached to the sliding door of the storage Will be described as an example. FIG. 1 shows an embodiment of a pull door with a sliding door latch according to the present invention. In addition, this figure has shown the state in which the sliding door was located in the door frame side edge, and the latch of the puller acted on the horizontal section in the center part. FIG. 2 shows a state when the pulling door with a latch for the sliding door is mounted in a mounting hole formed in the sliding door, and FIG. 3 shows a front appearance of the pulling portion of the sliding door on which the pulling handle is mounted. .
[0009]
In the figure, on the two rails 3 and 3 provided in the door frame 2 of the front opening of the storage body 1, there are sliding doors 4 and 4 a composed of a right outer door and a left inner door. It is arranged so that it can move left and right. At the both ends of the door frame 2, there is a shallow intersection 7 where the side end on the side where the pulling handle 10 of the sliding door is provided (that is, the outer door is at the right end and the inner door is at the left end). It is formed so as to confront each other.
[0010]
The pulling door mounting portion of the sliding door 4 has a panel shape having a vertical front plate 5 and an end plate 6 formed by bending the front plate 5 inward at substantially right angles. A vertically long mounting hole 8 is cut out in a state of hanging on the end face plate 6.
[0011]
A pull handle 10 with a latch according to the present invention is mounted in the mounting hole 8, and includes a pull frame 11, a latch piece 30 to be mounted on the pull frame, and the latch piece in the pull frame 11. An urging means 35 for urging is provided, and its basic configuration is as follows. That is, the puller frame 11 includes a rectangular frame portion 12 whose corresponding ends are in contact with the upper and lower ends and the inner end of the mounting hole 8 and whose outer end is exposed on the side end surface of the sliding door 4, and an outer end of the front end of the frame portion. And the front edge members 16 and 16a covering the vicinity of the inner end, the rear member 15 crossing the rear end 23 of the frame portion 12, and the frame portion 12 are pushed into the mounting hole 8 along the front plate 5 from the outer end side. Locking means 20 for locking the frame portion 12 to the mounting hole 8 at a plurality of positions when inserted, and a through window 17 is formed in the center of the outer front edge member 16 of the puller frame 11. ing. On the other hand, the latch piece 30 is formed of a substantially rectangular plate-like member whose outer periphery is slightly smaller than the inner periphery of the frame portion 12 of the puller frame 11, and protrudes forward (that is, protrudes toward the front side) in the center near the outer end thereof. A latch claw 31 having an inclined surface 32 whose outer side surface is inclined inward is provided, and an inner end of the latch piece 30 is attached to the inner end of the frame portion 12 of the puller frame 11 so as to be able to turn back and forth. An urging means 35 is interposed between the latch piece 30 and the back member 15 so that the front surface of the outer end of the latch piece 31 is brought into contact with the outer front edge member 16 of the pulling frame 11 and the tip of the latch claw 31 is The front edge member 16 is biased so as to protrude forward from the through window 17.
[0012]
On the other hand, in the shallow intersections 7 formed at both ends of the door frame 2, a latch receiving hole in which the tip of the latch claw 31 can advance and retreat at a position corresponding to the latch claw 31 of the pull handle 10 attached to the sliding door 4. 9 is formed, and in a position where the sliding door 4 is closed, the latch pawl 31 urged forward is aligned with the latch receiving hole 9 of the intersecting portion 7 of the door frame 2 and advances into the latch receiving hole 9, and the sliding door 4 is prepared to be locked.
[0013]
Next, the detailed structure of each constituent member of the latching handle 10 of the sliding door 4 having the above-described basic structure will be sequentially described below. First, the puller frame 11 has a bottomed, vertically long rectangular frame portion 12 whose periphery is in contact with the inner periphery of the mounting hole 8 formed in the sliding door 4, the front surface is open and the rear end is closed, and the front end inner end of the frame portion 12. A step 13 on the back side of the front overhanging portion 14 formed by projecting the (left end) side forward and widening the inner (left) end, and extending vertically outward from the upper and lower ends of the frame portion 12 and the step 13 And hooks 21 and 21 whose rear surfaces are the same surface, locking claws 22 and 22a and 22a formed on the circumferential surface of the frame part 12 with a slight rearward separation from the step part 13 and the hook part 21, and a frame part It has a notch groove 24 formed in the direction along the sliding door end face plate 6 near the outer end of the rear end 23. Further, front edge members 16 and 16a covering the front end opening are formed in the vicinity of the outer end (right end) and the inner end (left end) of the front end of the frame portion, and among these, in the center of the front edge member 16 on the outer end side A rectangular through window 17 is formed.
[0014]
In the above, the bottom surface member of the frame portion 12 is the back member 15 that supports the rear end of the front biasing spring 36 of the latch piece 30, and the frame portion extends from the rear end 23 of the upper and lower or left and right wall surfaces of the frame portion 12. What is necessary is just to form in the form which passes along the center, and it is not necessary to form continuously over the perimeter of the frame part rear end 23 like illustration. On the other hand, a front projecting portion 14 is formed by projecting forward near the inner end of the front end of the frame portion 12 and widening it to the left. It is a convenient solution when necessary. That is, the front overhanging portion 14 secures a mounting portion for rotatably mounting a latch piece 30 to be described later, reduces the width of the mounting hole 8 formed in the sliding door 4, and fits the sliding handle into the sliding door. Is to make small and shallow. Therefore, in the case of a sliding door having a sufficient thickness, the pulling handle 10 according to the present invention can be realized without the pulling frame 14 extending forward.
[0015]
Next, the latch piece 30 is a substantially rectangular plate-like member that is slightly smaller than the inner peripheral surface in front of the frame portion 12 of the puller frame 11, and bends forward slightly to the left from the center, and upper and lower ends near the inner end. Protrusions 33 having a circular cross section are formed on the edge, and on the other hand, a central portion in the vicinity of the right end (outer end) protrudes forward (front side) and has an inclined surface 32 inclined inward on the right side surface of the tip. A latch claw 31 is provided, and a rectangular concave seat portion 37 for abutting and supporting one end of the urging spring 36 at the center of the back surface and a support projection 38 formed at the center of the seat portion 37 are provided.
[0016]
The latch piece 30 is formed so that the width of the plate-like member is slightly narrower than the inner width of the frame portion 12 of the puller frame 11 and a protrusion extending outward is formed at the center of the outer end of the plate-like member. The latch claw 31 is formed so that the latch claw 31 protrudes from the front surface from the front portion or the width of the plate member is substantially equal to the inner width of the frame portion 12 of the pull frame 11. It may be formed to project forward from the front surface near the outer end.
[0017]
Since the latch claw 31 protrudes forward from the through window 17 of the front edge member 16 of the puller frame 11, the latch claw 31 has a vertically long approximately rectangular shape having a length of about 20 mm and a width of about 5 mm so as not to impair the design aesthetics. It is preferable that the through window 17 has an opening of about 0.5 to 1 mm larger than the size of the latch claw.
[0018]
The puller frame 11 and the latch piece 31 are advantageously manufactured by injection molding using a synthetic resin such as ABS plastics (acrylonitrile butadiene styrene polymer) or POM (polyacetal) having a little flexibility. The puller 10 of the present invention has a complicated shape, so that it can be manufactured at low cost, and in addition to being easy to assemble and install in the mounting hole 8, the synthetic resin is slightly flexible. Most preferably, injection molding is used.
[0019]
On the upper and lower inner surfaces of the front overhanging portion 14 of the frame portion 12, recesses 34, 34 into which the projections 33, 33 at the upper and lower edge of the latch piece 30 are fitted are formed near the inner end. As a result, the latch piece 31 is inserted from the front opening of the puller frame 11 into the flanges of the front edge members 16 and 16a, and the puller frame 11 is expanded vertically within the range of elasticity of the material, or further the latch piece 30. When the projections 33, 33 of the latch piece 30 are fitted into the recesses 34, 34 of the puller frame 11, the latch piece 30 rotates back and forth within the frame portion 12 with the fitting portion as a fulcrum. The leading end of the latch claw 31 can be moved forward and backward from the through window 17 of the front edge member 16. In this case, if the fitting between the projection 33 and the recess 34 is molded with a slightly high accuracy, the fitting allowance between the recess 34 and the projection 33 may be a very small amount of about 1 to 3 mm, and the pull frame at the time of assembly. 11 and the amount of elastic deformation of the latch piece 30 are small.
[0020]
Next, the urging means 35 is configured by compressing and mounting a spring 36 between the back member 15 of the frame rear end 23 and a rectangular concave seat portion 37 formed on the back surface of the latch piece 31. The spring 36 is engaged with the support protrusion 38 at the center of the seat portion 37 on the back surface of the latch piece, and the base end is brought into contact with the back surface member 15 of the frame portion 12. That is, the spring 36 urges the latch piece 30 forward by effectively using the concave seat portion even in a narrow gap, the outer end of the latch piece or the latch claw base is brought into contact with the outer front edge member 16 of the pull frame, The latch claw 31 protrudes forward from the through window 17 of the front edge member 16. Then, when the fingertip of the hand of the pulling frame 11 is hung and the latch piece 30 is pushed against the urging force of the spring 36, or the latch claw 31 is pushed, the latch piece rotates backward, and the latch claw 31 is moved as shown in FIG. Retreat to the state of the two-dot chain line. As the spring 36, a trapezoidal coil spring as shown in the figure may be used in order to effectively and reliably exert the above function in a narrow space. Unlike parallel coil springs, trapezoidal coil springs are compressed in such a way that adjacent coils enter inside and outside, and the length at the time of compression can be considerably shortened, and it is optimal as a biasing means provided in a narrow gap on the back side of the latch piece. Yes, rectangular concave seats complement that role.
[0021]
Next, with respect to the locking means 20, a stepped portion 13 on the back side of the front overhanging portion 14 of the frame portion 12, and a flange portion that extends vertically upward and downward of the frame portion 12 and whose back surface is flush with the stepped portion 13. 21 and 21, and locking claws 22 (see FIGS. 1 to 3) and 22a and 22a (see FIG. 3) formed on the frame portion 12 with a slight rearward separation from the step portion 13 and the flange portions 21 and 21, And a notch groove 24 formed in a direction along the sliding door end face plate near the outer end of the frame rear end 23. The front ends of the locking claws 22 and 22a and 22a are opposed to the back surface of the stepped portion 13 and the flange portion 21 with a slight gap therebetween, and the gap is the thickness of the front plate 5 at the edge of the mounting hole 8 of the sliding door 4. Set to be approximately equal to or slightly narrower than this. As shown in FIGS. 1 and 2, the locking claw 22 has a thin intermediate portion extending from the base portion protruding from the frame portion 12 to the tip head portion, and slightly presses the tip head portion in the front-rear direction. It can be elastically deformed. The side shapes of the locking claws 22a, 22a are not shown, but may be the same as the side shape of the locking claws 22 shown in FIGS. Slightly elastic deformation is possible. On the other hand, the notch groove 24 at the frame rear end 23 may be formed vertically between the upper and lower end portions in the vicinity of the outer end. However, since the notch groove 24 is a means for restricting the pullout frame from coming out to the outer end side, it is not only a perfect groove shape as shown in the figure, but also the wall surface at the outer end of both side walls of the groove. It can also be replaced with a notch step (not shown) lacking.
[0022]
Of the locking claws 22 and 22a, 22a, the locking claw 22 facing the stepped portion 13 on the inner end side of the frame portion 12 can be omitted, and at least the upper and lower flange portions 21, 21 of the frame portion. What is necessary is just to provide the latching claws 22a and 22a which oppose. In addition, the flanges 21 and 21 protruding from the top and bottom of the frame part 12 are not shown in the figure, but the upper and lower parts near the front end of the frame part are moved forward in the same manner as the step part 3 at the inner end of the frame part. An embodiment in which a stepped portion is formed by extending the protruding portion up and down and the locking claws 22a and 22a are disposed on the back surface of the stepped portion, for example, as in the above example is also possible.
[0023]
With the above-described configuration of the locking means 20, the pulling handle 10 assembled by mounting the latch piece 30 on the pulling frame 11 is inserted from the side end of the mounting hole 8 in the direction of the arrow shown in FIG. 4 is pushed along the front plate 5 and the flanges 21 and 21 and the step portion 13 and the locking claws 22a and 22 sandwich the edge of the mounting hole 8 of the sliding door front plate 5 and In addition to restricting movement and allowing lateral movement, the front end of the mounting hole edge of the sliding door end face plate 6 is engaged with the notch groove 24 (or the above-mentioned notch step portion) at the position where it is pushed in until it contacts the inner end side of the mounting hole 8. The left and right movements, that is, the pull-out of the puller frame 11 are restricted. FIG. 1 shows this mounting completion state. In this case, in order to avoid the interference claw 22a on the back side of the collar 21 from interfering with the end face plate 6 of the sliding door when the pulling handle 10 is pushed in, the end face plate 6 is formed with a notch for passing the catch claw (not shown). ing. In addition, when the puller 10 is mounted, the sliding door end face plate 6 interferes with the rear end of the puller frame 11 and pushes forward, and resistance acts. However, the gap between the mounting hole and the puller frame is set at an appropriate intersection. The setting and the slight flexibility of the plate structure of the sliding door and the flexibility of the pulling handle 10 and the locking claw 22a act synergistically so that they can be mounted so that plastic deformation does not occur.
[0024]
Next, the operation of the pulling door handle 10 having the above-described structure will be described. As described above, the puller 10 assembled by attaching the latch piece 30 to the puller frame 11 is pushed in along the front plate 5 of the sliding door from the side end of the mounting hole 8 in the direction of the arrow shown in FIG. Can be installed. The attached puller 10 is restricted by the locking means 20 from front to back and left and right. When the sliding door 4 fitted with the pulling handle 10 is closed, when the sliding door side end reaches the door frame side end intersecting portion 7, the inclined surface 32 at the tip of the latch claw 31 of the latch piece 30 biased forward is provided. As a result of abutting against the end of the intersecting portion 7 and pressing the jerks 32, the latch claw 31 is pushed into the puller frame 11, resulting in a state indicated by a two-dot chain line in FIG. At the position where the side edge of the sliding door 4 reaches the heel end of the door frame 2 and the sliding door 4 is closed, the latch claw 31 is aligned with the latch receiving hole 9 of the door frame intersection 7 and is latched by the urging force of the spring 36. The claw 31 advances into the latch receiving hole 9 and engages with this, and the sliding door 4 is locked. This state is shown by the solid line in FIG.
[0025]
When the sliding door 4 is opened, if the hand is put on the pulling frame 11, the latch piece 30 is pushed into the pulling frame as a result of the operation. As a result, the latch piece 30 rotates backward and the latch pawl 31 is engaged. Is released (the state indicated by the two-dot chain line in FIG. 1), and the pivot fulcrum side of the latch piece 30 that has been rotated backward is inclined so that the fingertip can easily be hooked from the bent portion of the latch 30 piece to the inner end surface. Therefore, the sliding door 4 can be easily opened by placing the fingertip on the inclined portion and the front edge member 16a on the inner end side of the pulling frame. On the other hand, when closing the sliding door, similarly, a hand is put on the pulling frame 11 to push the latch piece 30 into the pulling frame, and the gap between the leading end of the latching piece 30 and the front edge member 16 on the outer end side of the pulling frame. A gap is generated, and it becomes easy to close the sliding door 4 by putting a fingertip on the front edge member 16.
[0026]
As described above, when the sliding door 4 is closed, the latch automatically operates and the sliding door is locked, and the sliding door does not open due to the reaction and is less likely to be left in a half-open state. Even if the sliding door is not locked, the sliding door does not open during transportation or an earthquake, and the stored items can be prevented from jumping out and falling.
[0027]
Next, with respect to the locking means, FIG. 4 shows another embodiment of the locking means 20a in place of the above-described locking method using the stepped portion and the collar portion and the locking claw. FIG. 4 is a view of the state immediately before the pulling handle 10a is attached to the sliding door 4 as viewed from the obliquely upper front side. The pulling handle 10a shown in this figure forms guide grooves 40, 40 along the front end face in which the front plate 5 at the edge of the mounting hole 8a of the sliding door 4 is fitted in front of the upper and lower ends of the frame portion 12a of the pulling frame 11a. In addition, a similar groove-shaped locking recess 41 is formed at the inner end, and a notch is formed near the outer end of the frame rear end 23a in the direction along the end face plate of the sliding door mounting hole edge as described above. A groove 24a (which may be a notch step similar to that described above with reference to FIGS. 1 to 3) is formed. In this case, as shown in FIG. 4, the opening height of the sliding door end face plate 6 is substantially equal to the height of the frame portion 12a of the pulling frame 11a. The opening height is narrower than that and substantially equal to the height between the bottom portions of the upper and lower guide grooves 40, 40, and the position of the notch groove 24a (or the notch step portion) is related to the inner end of the puller frame 11a. The sliding door end face plate 6 is formed at a position facing the frame rear end 23a when the stop recess 41 abuts the inner end of the mounting hole 8a.
[0028]
As a result, the guide groove 40 acts as a guide when the puller 10a is pushed into the mounting hole 8a along the direction of the arrow and mounted. The forward and backward movement of the puller frame 11a is restricted in cooperation with the locking recess 41 at the inner end. On the other hand, the front end of the end face plate 6 at the edge of the mounting hole 8a of the sliding door 4 engages with the notch groove 24a (or the above-described notch step portion) to restrict the left-right movement of the puller, that is, the withdrawal. In the above description, the engaging recess 41 at the inner end of the puller frame 11a may be omitted, and in this case, the same effect can be obtained. Although not shown, the guide grooves 41 and 41 as described above may be formed in place of the locking claws 22a and 22a on the back side of the flange portions 21 and 21 in the above-described example.
[0029]
The puller 10a of FIG. 4 is different in the locking means as described above and different in that a front end projecting portion is not formed at the front end of the frame portion 12a, but the other structure is based on the above-described FIGS. Since it has the same structure as the description and the mounting procedure and operation are substantially the same as those described above, description of the operation is omitted.
[0030]
【The invention's effect】
The pulling door with a latch for a sliding door of the invention according to claim 1 as described above has a pulling frame, a latch piece attached to the vicinity of the inner end of the frame portion of the pulling frame, and a latch piece attached to the rear of the pulling frame. Only three members of the spring urging forward can be used. Then, when the puller is assembled and pushed along the sliding door front plate from the outer end side to the inner end of the mounting hole on the sliding door side end, the one-touch operation automatically activates the locking mechanism of the puller. Installation is complete. When closing the sliding door, when the sliding door side end reaches the intersection of the door frame with the sliding door side end, the latch pawl tip contacts the inner end of the intersection and is pushed into the pulling frame, and the sliding door side end In the position where the door reaches the end of the door frame crossing portion, the latch pawls advance into the latch receiving holes by the forward biasing action of the latch pieces, and the sliding door is locked. On the other hand, when opening the sliding door, if you put your hand on the puller frame and push the latch piece, the latch piece will rotate backward, the latch pawl will be disengaged, and the pivoting fulcrum of the latch piece will turn backward Since the side is inclined and the fingertip is easily hooked, the sliding door can be easily opened if the fingertip is hooked on the inclined portion and the front edge member on the inner end side of the pulling frame. In other words, the pulling door with a latch for a sliding door according to the present invention does not need to be housed and installed in a narrow internal space of the sliding door or the storage body. Despite its simple structure, it has all the necessary functions, has a small number of parts, and the handle frame and latch piece can be manufactured at low cost because it can be injection-molded using synthetic resin, and the sliding door opening of the storage Since there is no protrusion to the side, there is no risk of catching a hand or a stored item, and there is an effect that the design and aesthetic appearance are not impaired.
[0031]
Moreover, Claim 2 of this invention And 3 The present invention relates to a specific form of the locking means for the mounting hole in the pulling handle with a latch for a sliding door according to the present invention. It becomes easy to integrally mold the locking part to the frame part during hand frame injection molding, and it is a one-touch operation that only pushes along the sliding door front plate from the outer end side of the mounting hole, that is, from the sliding door end plate side to the inner end. Can be attached to the pull handle. That is, there is an effect that it becomes easy to significantly reduce the manufacturing and assembly costs.
