Description

[Detailed description of the invention] [Industrial application field] The present invention is a pull device that is used when opening and closing objects such as drawers of desks and furniture, lockers, cabinets, room entrance doors, sliding doors, etc. It is related to the structure of

[Conventional technology]

Conventionally, many pull devices of this type have a circular or elongated rectangular recess formed on the front surface of the opening/closing body, a finger rest plate is embedded in the recess, and the finger is hung on the inner peripheral edge of the finger rest plate.

However, if there is no finger rest on the inner peripheral edge of the finger rest, the finger rest becomes unstable, so it is necessary to increase the depth of the finger rest.

Furthermore, when the finger rest plate has an elongated rectangular shape, forming a finger rest part on the inner circumferential edge of the finger rest plate will narrow the finger insertion gap accordingly. Moreover, when inserting a finger, if the fingertip is bent toward the finger rest, the outside of the finger will hit the inner peripheral edge on the opposite side to the inner peripheral edge where the finger was inserted, making it impossible to ensure a deep and secure finger rest. There is.

As a prior art to eliminate this drawback,
- In Publication No. 19651, the handle body is rotatably pin-mounted to a handle hole that is closed at the rear of the door and opens only at the front, and the handle body has a V-shaped cross section that extends forward on both left and right sides of the pivot point. A shaped fin is formed, and a gap is formed between the side edge of the pull hole and each of the fins to allow a finger to enter, while a pair of left and right spring pieces are provided on the handle body in the opposite direction to the left and right fins. something is disclosed.

[Problem to be solved by the invention] In the prior art, when you put your finger on the back side of one fin in the handle body and pull it toward you, the spring piece on the opposite side comes into contact with the rear surface of the handle hole and presses it. When the force on the fin is removed, the handle body returns to its original position due to the biasing force of the spring piece.
Since the fingers are inserted between the left and right fins of the handle body and the edge of the pull hole, it is necessary to prevent the outside of the fingers from touching the side edges of the pull hole.

Therefore, there was a problem in that the pull hole became extremely large and the entire pull device became bulky.

The object of the present invention is to solve the problems of the prior art by forming the pull body into an elongated shape while still allowing the finger to be placed deeply and reliably.

[Means for solving problems]

Therefore, in the present invention, a pull device is provided in which a pull hole is bored in an opening/closing body such as a furniture drawer or a door, and a pull main body is rotatably attached to the opening/closing body facing from the pull hole to the surface side of the opening/closing body. The pull main body is disposed on the front surface of the frame that fits into the opening/closing body from the back side, and the pull main body is formed into a cylindrical shape with a substantially semicircular cross section, and the inner diameter side of the opening edge of the semicylindrical part has a pair of longitudinal finger hooks. A rotating shaft is provided at both ends of the pull main body, and a pair of supports rotatably supporting the rotating shaft are removably attached to the frame, Both supports are provided with spring means for returning the pull main body to a neutral position of rotation.

[Functions and effects of the invention]

In this way, in the present invention, the main body of the handle is formed to have a substantially semi-cylindrical cross-section, and is configured to serve as a pair of long finger-holding parts that can be placed by inserting the fingers into the inner diameter side of the opening edge of this substantially semi-cylindrical part. Because of this, there is no need to hook your fingers on the inner periphery of the handle hole or from the outer periphery of the handle body as in the past.

Therefore, by simply placing the pull body of the present invention in front of an opening/closing body such as the front plate of a drawer or the door plate of a lock car, there is no need to make any modifications to the pull hole, and the inside of the pull hole can be The peripheral edge and the outer periphery of the pull main body can be arranged very close to each other.

Moreover, this pull body has rotating shafts at both ends.
By being rotatably supported by a pair of supports, when you bend your fingertips and pull the pull body, the pull body can swing so that the finger hook on the side where your fingers are hooked comes out on the surface of the opening/closing body. Because of this, the finger hook can maintain a deep state.

Therefore, even though the pull body is formed into an elongated shape, the finger can be placed deeply on the pull body.
Moreover, since it becomes reliable, the opening/closing operation of the opening/closing body can be performed smoothly and lightly.

The rotation shafts at both ends of the pull body in the longitudinal direction are removably attached to the support body, and this support body is attached to the frame body located on the back of the pull body, which simplifies the assembly work of the pull device. play.

〔Example〕

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

The mirror plate 2 of the drawer 1 is made by overlapping a front plate 2a and a rear plate 2b, which are made by bending thin steel plates, at their circumferential edge plates with an appropriate gap between them, and near the square parts of the upper and lower circumferential edges. It is made by spot welding 4. Reference numeral 5 designates a top-open tray that is fixed to the rear plate 2b of the mirror plate 2 with screws 6.

The pull device 3 consists of a frame 7 that fits into the mounting hole 8 of the rear plate 2a, a pull main 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, and Both of the pull hole 8 and the pull hole 9 are formed in a horizontally long oval shape, but the horizontal dimension of the pull 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 diameter side thereof to become 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 to be able to be removably fitted into 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 claws 17 at appropriate positions in the longitudinal direction, and each of the protruding claws 17 is attached to the rear plate 2.
It engages with the engagement hole 18 of b, and is installed in a so-called fit-and-fit 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.

Note that if the spring pieces 16 in the support body 11 become fatigued or break due to long-term use,
It is only necessary to replace the defective support 11 without replacing other parts such as the pull body 10, etc., and it is possible to replace the defective support body 11 without replacing other parts such as the pull body 10. No need to replace the whole thing.

The pull device of the present invention may be arranged so that the axis of rotation is in the vertical direction.
