Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of an opening/closing body such as a mirror plate in a desk or a drawer of furniture, a locker, or a door that freely opens and closes the opening of a cabinet.

[Conventional technology]

Conventionally, when this type of opening/closing body was formed from a thin metal plate such as a thin steel plate, the metal plate itself was thin, so in order to give the opening/closing body an appearance of thickness, it was necessary to The side edges are bent to have a U-shaped cross section, and a rear plate made of a thin metal plate is superimposed on a portion of the circumferential side edge parallel to the wide front plate surface, and both plates are fixed by welding or the like.

[Problem that the invention attempts to solve]

However, since both the front and rear plates are thin,
It is difficult to perform so-called fillet welding. Therefore, it is preferable to perform so-called resistance welding (spot welding) with the two plates overlapped.

However, in order to perform resistance welding, it is necessary to apply pressure with a pair of welding electrodes so as to sandwich both plates in that area, and for this reason, the side edges of both plates must be bent into an L-shape and brought together. However, the bent side edges are exposed to the outside,
The problem was that the appearance was extremely poor.

The purpose of the present invention is to solve this problem, and also to protect the contact portion between the back surface of the opening/closing body and the front surface of the main body of the furniture or the like.

[Means for solving problems]

Therefore, in the present invention, an opening/closing body such as a mirror plate or a door that closes the opening of a furniture main body such as a drawer or cabinet is composed of a front plate and a rear plate made of thin metal plates, and the peripheral edge of the front plate and the rear plate are made of a thin metal plate. The circumferential edges of the plates are bent toward the other plate, and overlapped so that the inner surface of the circumferential edge of the front plate is in contact with the outer surface of the circumferential edge of the rear plate. In the vicinity of the peripheral edges, an opening hole is drilled into which a welding electrode is inserted toward the point where the peripheral edges of both plates are to be resistance welded, and in this opening hole there is a rubber plate that contacts the front surface of the furniture body. The structure is such that a shock absorber such as those made by the Company, etc. can be removably fitted into the body.

[Functions and effects of the invention]

In this way, in the present invention, when the circumferential edges of both the front and rear thin metal plates are overlapped, they are stacked so that the circumferential edge of the front plate becomes the outer surface of the circumferential edge of the rear plate. , the end face of the peripheral edge of the rear plate is not exposed to the outside, and the front plate and rear plate are separated by approximately the dimension of the peripheral edge, making the opening and closing body thick in appearance. I can do it.

Then, one of the welding electrodes used for resistance welding at the overlapping portion of the circumferential edges of the front and rear plates is positioned within the thickness of the opening/closing body, in other words, so that it can be positioned between the front plate and the rear body. Since the opening hole is formed on the rear plate side, no protrusion of any kind is formed on the outside of the thick part of the opening/closing body, and the appearance of the opening/closing body from the front side is improved.

Furthermore, since the member for closing the opening hole is made of a cushioning body made of rubber or the like, and this cushioning body can be brought into contact with the front surface of the main body of furniture etc. in the vicinity of the opening, the cushioning body is It can serve the dual roles of a plug that closes the hole and a door stop that eliminates the collision noise when the back of the opening/closing body hits the front of the main unit and prevents them from damaging each other, and the structure is simple. It has a certain effect.

〔Example〕

Next, an embodiment in which the present invention is applied to a drawer will be described. FIGS. 2 and 3 show a drawer 1 in a desk, and a pull device 3 is attached to a mirror plate 2 of the drawer 1.

The open-top tray 5 has its front end surface fixed to the rear plate 2b of the mirror plate 2 with screws 6, and can be inserted into the case body 1a of the drawer 1 through the front opening.

Therefore, the peripheral portion of the rear plate 2b of the mirror plate 2 comes into contact with the front surface of the case body 1a.

The end plate 2 of the drawer 1 has a front plate 2a and a rear plate 2b made of thin steel plates arranged with an appropriate gap between them, and the circumferential parts of both the front and rear plates 2a, 2b are folded toward the wide side of the other plate. Curved and each peripheral edge 20a, 20b
Polymerize at . At this time, the front plate 2a is stacked so that the circumferential edge 20a of the front plate 2a is on the outside and the circumferential edge 20b of the rear plate 2b is on the inside.

Incidentally, reference numeral 23 denotes a lightweight honeycomb body made of paper or the like that is inserted between the front plate 2a and the rear plate 2b.Thereby, the end plate 2 can be configured to be lightweight but not warped.

Then, resistance welding (spot welding) 4 is performed near the square parts of the upper and lower peripheral edges of the peripheral edges 20a and 20b of both the front and rear plates, and a pair of welding electrodes (not shown) are used for this resistance welding. Circumferential edges 20 of both front and rear plates
A and 20b are clamped and pressurized from the inside and outside. At this time,
Opening hole 2 in the rear plate 2b near the location where resistance welding 4 is to be performed.
1, one of the welding electrodes is inserted into the end plate 2 through this opening hole 21.

Reference numeral 22 denotes a buffer body made of an elastic material such as rubber, and each buffer body 22 is removably fitted so as to close each opening hole 21 from the outside.

The location where this buffer body 22 is located, and by extension the location where the opening hole 21 is located, is at the front surface near the opening of the case body 1a of the drawer 1.

According to this configuration, the end plate 2 can be provided with a thickness by resistance welding the bent circumferential edges of the front plate and the rear plate. In that case, since the openings 21 are bored in the vicinity of the circumferential edge 20b of the rear plate 2b, one of the welding electrodes for resistance welding can be easily exposed to the inside of the mirror plate through each opening 21. Resistance welding is possible, and there are no protrusions on the peripheral edges of both the front and rear plates, resulting in a beautiful appearance.

Moreover, after the welding work, each of the openings 21 is closed with a buffer body 22, so that the appearance of the end plate 2 is improved.
Moreover, when the tray 5 of the drawer 1 is pushed into the case body 1a, the back surface of each buffer body 22 on the end plate 2 comes into contact with the front surface of the case body 1a (see FIG. 5), and the rear plate 2a of the end plate 2 This eliminates the possibility of contact with the front surface of the case body 1a, thereby eliminating collision noise.

It goes without saying that the present invention can be applied not only to the mirror panel of a drawer, but also to opening/closing bodies such as opening/closing doors of furniture such as locker cabinets.

The pull device 3 includes a frame 7 that fits into the mounting hole 8 of the rear plate 2a, a pull body 10 that faces the front through the pull hole 9 of the front plate 2a, and a pair of left and right supports 11, 11. Both the mounting hole 8 and the handle hole 9 are formed in a horizontally long oval shape, but the horizontal dimension of the handle hole 9 is shorter than that of the mounting hole 8.

The pull main body 10 is disposed on the front surface of a frame 7 having a U-shaped cross section and fitted from the back side of the mirror plate 2.
is formed into a cylindrical shape with a substantially semicircular cross section, and both longitudinal ends of the substantially semicylindrical portion are formed into hemispherical shell shapes. A pair of upper and lower opening edges along the longitudinal axis of the substantially semi-cylindrical portion of the pull main body 10 are configured to form an inward protrusion on the inner radial side to form a pair of longitudinal finger hooks 10a, 10a.

Fin portions 13 having an inverted V-shaped cross section are integrally provided at both ends of the pull main body 10, and the fin portions 1
A pair of left and right rotating shaft portions 12, 12 are integrally molded to protrude from the base of the V-shaped surface of No. 3.

A pair of supports 11, 11 that rotatably support each rotation shaft 12 are formed in a substantially U-shape in cross section, and both legs 11a, 11a of each support 11 are connected to both left and right ends of the frame 7. The substrate 11b of the support body 11 is configured so that it can be removably inserted into the guide grooves 14, 14 formed along the longitudinal direction of the support body 11.
The free edge of the handle body 10 has a rotating shaft portion 1.
A notch support groove 15 into which the holder 2 fits is formed.

Further, a pull main body 10 is provided on both supports 11.
A spring means is provided for returning the rotary shaft to the neutral position when swinging about the 12 rotation shafts.

In one embodiment, each support 11 has the support groove 1 extending from the rising portion 11c of the substrate 11b.
The plate-shaped spring piece 16 is made to protrude like a cantilever toward the free end with the base plate 11.
The fin portion 13 of the pull main body 10 is sandwiched between the rear surface side of the pull handle body 10 and the rear surface side of the pull handle body 10.

Each of the supports 11 is an injection molded product made of synthetic resin, and at this time, the spring pieces 16 are formed so as to be inclined toward the back side of the substrate 11b as they go toward the free end side (sixth (See the dashed line in the figure), the spring force is made to act sufficiently on each of the fin portions 13.

Further, the inverted V-shaped fin portion 13 is such that when the pull main body 10 rotates around the rotation shaft portion 12, one surface of the fin portion 13 contacts the back surface of the substrate 11b of the support body 11. By touching,
It also serves as a stopper that prevents further rotation.

The outer peripheral surface of the frame 7 that fits into the mounting hole 8 of the rear plate 2b of the end plate 2 in the drawer 1 is provided with protruding pawls 17 at appropriate positions in the longitudinal direction.
It engages with the engagement hole 18 of the holder, and is mounted in a so-called "fitting" manner.

In this configuration, since the length of the pull hole 9 is shorter than the mounting hole 8 of the rear plate 2b, the frame body 7 can be attached to the rear plate 2b.
When inserted from the side, the pair of left and right supports 11, 11 attached to both left and right ends of the frame 7 are not exposed to the surface side of the front plate 2a, and The pull body 10, which is rotatably supported, faces the front plate 2a so that its opening edge slightly protrudes from the pull hole 9 toward the surface of the front plate 2a.

To open the drawer 1, insert your finger into the opening edge from the inner diameter side of the approximately semi-cylindrical pull main body 10, hook your finger on one of the finger hooks 10a, and pull it forward.

At this time, depending on the bend of the fingertip, the handle body 1
0 rotates appropriately around the rotation shaft portion 12, 12 locations. At this time, the spring pieces 16, 16 on the left and right supports 11, 11 elastically support each fin portion 13 of the pull main body 10.

For example, when opening the drawer 1 with the fingers of the pull body 10 facing downward, the fingertips are bent downward, and the opening of the pull body 10 is diagonally upward, as shown by the dashed line in FIG. When opening the drawer 1 with the drawer facing upward, the opening of the pull main body 10 will face diagonally downward as shown by the dashed line in FIG.

In any case, the fingertip inserted into the inner diameter opening of the pull main body 10 can be kept deeply and securely hooked on the fingerrest 10a, and the outside of the fingertip will not collide with the fingerrest 10a on the opposite side, so the fingertip can be smoothly inserted. Drawer operation becomes possible.

When the user releases his or her finger from the pull body 10, the elastic restoring force of the spring piece 16 causes the pull body 10 to return to its neutral position such that its opening is approximately perpendicular to the end plate 2 of the drawer 1.
