Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure such as a drawer of a double door of a library or a file cabinet.
[0002]
[Prior art]
Generally, the door and drawer front plate are made of a thin metal plate such as iron, and if the door or drawer front is large, the thin plate will not be rigid enough, so the frame body with a U-shaped cross section will be placed on the back side. It is often provided by spot welding or the like. In addition, as a handle for opening and closing the door or the like, a member called a handle (referred to as a handle main body (and a finger hanging portion) of the present application) is attached to a plate-like main body portion of the door or the like. Furthermore, the door or the like is usually provided with a mechanism called a latch mechanism, and the door or the like is prevented from being inadvertently opened by the action of the latch mechanism at the normal time. The latch mechanism is interlocked with the pulling handle, and by pulling the finger-holding portion of the pulling handle with a hand, the latch by the latch mechanism is released and the door or the like can be opened.
[0003]
Since such a puller main body has a space in which a finger can be inserted, when it is attached to the plate-like main body, it protrudes to the back side and does not always have a good appearance when the door or the like is opened. Moreover, when it has a finger hook part interlock | cooperated with a latch mechanism, the beauty | look is further impaired. Therefore, in order to cover this handle, a back cover having a generally rectangular shape in front view is often attached. In the case of mounting the back cover, when a reinforcing frame body is conventionally provided as described above, it is often mounted and held by engaging the folded portion of the edge portion of the plate-like main body section with the frame body. It was. If there is no reinforcing frame body or if it is located far away, a separate member that replaces the reinforcing frame body is provided on the back side of the plate-like main body in order to engage one side of the back cover. It was necessary to weld it separately to the position.
[0004]
[Problems to be solved by the invention]
However, as described above, the back cover is structured to be mounted so as to extend between the edge folded portion of the plate-like main body part and the reinforcing frame body or another member. The plate-like main body (the edge turn-up portion), the reinforcing frame body or another member, and the three parts of the handle main body having an opening into which the finger hook provided on the back cover is inserted. However, when the back cover itself is inserted, the accuracy of each component and the respective mounting accuracy enabling the engagement of the four components is required, and the mounting is not easy. When the latch mechanism is not provided, the back cover is engaged with two parts, that is, the plate-like main body (the edge folded portion thereof) and the reinforcing frame body or another member, and the back cover itself is inserted. Each component accuracy enabling each of the three components to be engaged and their respective mounting accuracy is required, and it is not possible to easily mount the components without the latch mechanism. Further, when the reinforcing frame body is not used, the above-described separate member is required, which is wasteful in terms of the number of parts and cost.
Therefore, an object of this invention is to provide the door etc. which attached the back cover simply.
Moreover, it aims at provision of the door etc. which attached the back cover at low cost.
[0005]
[Means for Solving the Problems]
In view of the above-described object, in claim 1, the handle main body is attached to an opening provided in a plate-like main body such as a door, and the door or the like is closed at a back cover that covers the handle main body from the back side. There is provided a finger hook portion that can drive a latch mechanism that can be opened from the door, and the finger hook portion is a door or drawer structure exposed in a front space of the puller body, and the back cover is attached to the puller body. It is attached by fitting without using a set screw, and is held and attached to the handle main body, and the back cover is also engaged with an edge turning portion of the plate-like main body, and the pull main body is the opening In the state of being attached to the part, it is in an engagement relationship that cannot be pulled out to the back side of the plate-like main body part, and at least a partial region of the peripheral part of the back cover is in contact with or close to the back side of the plate-like main body part The finger grip is attached to the bottom surface of the handle main body. An open part into which the part is inserted is provided, and in the bottom surface of the handle main body located at the edge of the open part, there is provided a stepped part protruding to the back side and retracted on the front side, and the bottom part of the back cover Is provided with a stepped portion projecting to the surface side, and the stepped portion is engaged so as to overlap the surface side of the stepped portion of the main body of the handle, and further, corresponding to the engagement position of these stepped portions. The bottom surface of the back cover is provided with a narrow hole extending in the vertical direction, and two convex engaging portions that are vertically separated from the stepped portion of the puller body protrude toward the back side of the puller body. Each of the narrow holes is press-fitted and fitted into the upper and lower parts of the narrow hole, and a key cylinder part is mounted on the puller body. The engaging part of the cylinder part is inserted into the hole provided in the finger-hanging part. To provide a structure of a door or drawer, characterized in that.
Exposure to the front space does not mean that it can be seen by an external user. Although it may be visible, the case where the wall part which is a part of a handle main body is provided in the front position of a finger-hanging part so that it cannot be visually recognized by a user is also included.
[0006]
Since the back cover is attached to the main body of the pull handle by fitting, there is no need for a reinforcing frame body or separate parts as in the prior art, and the number of parts required for mounting the back cover can be reduced by one. Accordingly, the mounting accuracy is low, and the mounting can be easily performed, and the cost can be reduced. Furthermore, since it is attached by fitting, it is not necessary to use screw parts, and assembly is quick and simple. Since not only the handle main body but also the edge folded portion of the plate-like main body is engaged and attached, the stability of the back cover is further improved, and the back cover is less likely to be loose due to the movement of the finger hooking portion. In addition, since the plate-shaped main body is sandwiched between at least a part of the periphery of the back cover fitted to the pull-up body and the main body of the back cover, both the pull-up body and the back cover are stable after assembly. Will improve.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail based on an embodiment shown in the accompanying drawings.
FIG. 1 is a front view of an essential part of only a plate-like main body portion of one door (right door) of a double door according to the present invention, FIG. 2 is a front view of a door incorporating a handle main body, and FIG. 3 is an arrow of FIG. FIG. 4 is a cross-sectional view of only the handle main body of FIG. 3. A line L1 in FIG. 1 indicates a position corresponding to an arrow line CC in FIG. The left edge portion of the plate-like main body portion 10 made of a sheet metal of the right door is formed at the edge folded portion 10F. Further, a rectangular opening 10K as shown in the figure is provided near the edge turning portion and on the right side. On the right vertical edge of the opening, cutout portions 10A are provided at two locations on the top and bottom. Moreover, it is the height position within the range of the vertical edge which is the up-down direction of the opening 10K, Comprising: The notch part 10FK is provided in the edge part of the edge folding | returning part.
[00 08 ]
The pull handle body 12 is made of a synthetic resin such as ABS resin, and the front side is recessed so as to have a space KK and protrudes to the rear side. The cross section is shown in FIG. 3 and FIG. FIG. 2 shows a front view shape. This pull main body 12 is attached to the opening 10K from the front side. In this example, a flange 12F is provided on the front side edge portion (lower end portion in FIG. 4) of the handle main body. Further, another flange 12F ′ is provided in the vicinity of the left side edge of the pulling body with an interval of about the thickness of the plate-like main body 10 from the flange, and a gap 12FF ′ is provided between them. Is formed.
[00 09 ]
On the other hand, in the vicinity of the right edge of the handle main body, an interval about the thickness of the plate-like main body portion 10 is provided from the flange, and in this example, the convex portion 12T is formed to protrude outwardly by being separated into two upper and lower portions. Has been. A gap portion 12FT is formed between these and the flange 12F. The pulling body is mounted so that the plate-like main body 10 is sandwiched between the gaps 12FF ′ and 12FT. Each said convex part 12T respond | corresponds to the position of each notch part 10A of opening. However, the cutout portion 10A and the convex portion 12T may not be provided.
[00 10 ]
On the other hand, the back cover 16 is also made of synthetic resin, and the front view is substantially rectangular as shown by the broken line in FIG. 2, and the cross section is a U-shape as shown in FIG. It forms a box shape as a whole. A narrow hole 16K extending in the vertical direction is provided at a position about 1/3 from the right end of the left and right width of the bottom surface portion (that is, a position closer to the center rather than the end). A stepped portion 16D protruding in a stepped shape is formed on the front side when assembled (inside the box) so as to cover the edge.
A stepped portion 12D and a convex engaging portion 12K are formed in the pulling body at positions corresponding to the stepped portion and the narrow hole. Further, between the other flange 12F ′ and the stepped portion 12D, there is an open portion 12KK (FIG. 4) in which a finger-hanging portion 14 described later is opened so as to be inserted from the rear side of the handle main body.
[00 11 ]
The stepped portion 12D and the engaging portion 12K are formed so as to protrude on the back side of the handle main body, and the stepped portion 12D engages in a state where it is submerged on the back side of the stepped portion 16D, and the convex engaging portion 12K. Is press-fitted into the narrow hole 16K. In this way, the back cover is fitted to the pulling body. However, in this example, a rib-like portion 16K (FIGS. 2 and 3) protrudes and extends in the left-right direction on the back side near the left end portion of the back cover, and the rib-like portion 16K has the edge portion described above. Engage with the end notch 10FK of the folded portion 10F to prevent the left region of the back cover from being deformed so as to be separated from the plate-like main body 10 to the rear side mainly by a biasing force of a coil spring 22 described later. Yes. That is, the back cover is engaged not only with the fitting main body by the stepped portion 16D but also with the folded edge portion of the plate-like main body portion, thereby increasing the mounting stability .
[00 12 ]
Furthermore, in this example, most of the peripheral edge 16 </ b> T as an example of the back cover peripheral part is close to the back surface of the plate-like main body part 10. Therefore, in spite of the fitting engagement by the stepped portion 16D and the like, even if the back cover is somewhat rattled, the peripheral edge of the handle body 12 is engaged with the stepped portion 12D. When the portion 16T interferes with the back surface of the plate-like main body portion 10, backlash is prevented and stabilized. Due to the presence of the flange 12F, the attached puller main body 12 does not pass through the opening 10K of the plate-like main body part and pulls out to the rear side. Even if the back cover is pulled rearward by any force, The engagement combination of the back cover and the handle main body is prevented from moving. Further, in the engagement structure between the handle main body and the back cover, there are various forms such that the stepped portion 12D may be a flat portion flush with the bottom wall of the handle main body.
[00 13 ]
The relationship between the known latch mechanism and the back cover will be briefly described below. A pivot portion 14J is attached to the back cover 16 so as to be able to rotate about the axis center. A finger hook 14 is integrated or fixed to the pivot portion. When the back cover is attached to the pulling body, the finger-hanging part is exposed to the front space KK through the opening part 12KK of the pulling body described above. When a hand is put in the door puller main body space KK thus assembled, and the finger is hooked and pulled on the finger hooking portion 14, the pivot portion is rotated, the latch mechanism is operated, and the door can be opened.
[00 14 ]
At this time, the finger hooking portion is pulled (rotates) while compressing the coil spring 22 disposed between the tongue-like portion 14S provided at a predetermined position of the pivot portion and the bottom surface of the back cover. Therefore, it can be pulled while feeling an appropriate resistance force. Furthermore, when the door is closed and the finger is released from the finger hook, the finger hook is returned to the original closed position by the biasing force of the coil spring together with the pivot.
[00 15 ]
In this embodiment, a key cylinder portion 20 is mounted on the handle body, and an upper portion (not shown) of the engaging portion 20K enters the hole portion 14H of the finger hook portion by hooking the key. As a result, the finger-hanging portion cannot be pulled and the door cannot be opened. This key mechanism is the same in the case of a conventional door, and is an example in which a predetermined accuracy is required for the assembling relationship between the handle main body and the back cover (finger holding portion). The lower the accuracy required for such assembly, the easier the assembly. In the door of the present application, one assembly-related part is reduced compared to the conventional one (there is no reinforcement frame body or another part as an assembly target), and the required accuracy is low.
[00 16 ]
In the above embodiment, the explanation has been given by taking the kannon type door that opens to the left and right as an example. It can also be applied to pulling. Therefore, for example, the hook 18 of the latch mechanism may not be a hook that extends in the up-and-down direction as in the above example, but may extend in the left-right direction and the finger-hook portion may move in the up-and-down direction. That is, it may be a front plate portion in which the horizontal direction in FIGS. 2 and 3 is the vertical direction.
[00 17 ]
【The invention's effect】
As is clear from the above description, according to the present invention, it is possible to provide a door or the like with a simple back cover.
