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]

Among this type of pull device, when inserting a finger into the pull body embedded within the thickness of the opening/closing body,
Japanese Utility Model Publication No. 56-19651 discloses a prior art technique that allows the finger to be placed deeply and securely.
The pull body is rotatably pin-mounted to the pull hole that is closed at the rear of the door and opens only at the front.
Fins with a V-shaped cross section are formed extending forward on both the left and right sides of the rotation fulcrum, and a gap is formed between the side edge of the pull hole and each of the fins for inserting a finger, while the pull body is provided on both the left and right sides. A device is disclosed in which a pair of left and right spring pieces are provided in opposite directions to the fins.

[Problem that the invention attempts to solve]

In the prior art, when you put your finger on the back side of one of the fins in the pull body and pull it toward you, the spring piece on the opposite side comes into contact with the rear surface of the pull hole and is bent, and when the force on the fin is removed. The biasing force of the spring piece restores the handle body to its original position.
Since the finger is inserted between the left and right fins of the pull body and the edge of the pull hole, it is necessary to prevent the outside of the finger from touching the side edge of the pull hole.

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

Further, since the rotation shaft of the pull body must be located within the thickness of the opening/closing body, it takes time and effort to attach the rotation shaft and the pull body. In particular, when the opening/closing body is made of wood, there is a problem in that it is difficult to securely attach a member that is placed on the back side of the pull body and closes the back side of the pull hole.

In this invention, the pull main body is configured to be rotatable so that the finger can be hooked deeply and reliably, but the entire pull device can be easily attached to and detached from the opening/closing body, and it is firmly attached. In this way, the purpose is to solve the conventional problems.

[Means for solving problems]

Therefore, in the present invention, a pull hole is drilled on the front side of an opening/closing body such as a furniture drawer or door, and a mounting hole longer than the pull hole is bored on the back side of the opening/closing body. Supports are removably attached to both ends of the front side of the longitudinal frame that fits into the attachment hole from the back side.
A cylindrical pull body with a substantially semicircular cross section is rotatably mounted between the two supports, and the pull body is inserted from the pull hole toward the surface side with the substantially semicylindrical opening facing forward. On the other hand, a front frame body with a flange surrounding the inner periphery of the handle hole is detachably engaged with the longitudinal frame body.

[Functions and effects of the invention]

As described above, in the present invention, since the pull main body is formed to have a substantially semi-cylindrical cross-section, the substantially semi-cylindrical opening can be used as a finger resting portion on which a finger can be placed by inserting the finger into the inner diameter side of the opening.

This pull body is rotatably supported by a pair of supports at both ends, so that when you bend your fingertips and pull the pull body, the finger hook on the side where your fingers are hooked will open and close. Since it can be rotated so that it appears on the surface of the finger, a deep state of finger hooking action can be maintained.

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.

In addition, since the pull hole that the pull body faces is shorter than the length of the longitudinal frame that covers and supports the pull body from the back, the longitudinal frame and the pair of supports attached to both ends of the pull body are It fits through the mounting hole, but does not come out from the pull hole toward the front side. Therefore, even if you put your finger on the handle body and pull the opening/closing body forward, it will not fall off.

Moreover, a front frame with a flange is inserted into the pull hole from the surface side of the opening/closing body, and this front frame is engaged with the longitudinal frame, so when both are engaged, the entire pull device can be opened/closed. This means that it can be firmly attached to the body without falling off either on the front side or the back side.

Further, since the inner circumferential edge of the front frame that fits into the pull hole and the outer circumference of the pull body can be disposed very close to each other, the entire pull device can be formed into an elongated and compact device.

Since the longitudinal frame body and the front frame body are simply engaged with each other, there is no need to make any modifications to the mounting holes and pull holes of the opening/closing body such as the end plate of the drawer or the door plate of the locker. The opening/closing body is particularly easy to attach even when the inner circumferential surface of the hole cannot be intricately worked, such as when the opening/closing body is made of wood.

〔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 mirror plate 2 of the drawer 1 has a pull device 3 of the present invention.
Attach.

The end plate 2 of the drawer 1 is made of wood and has approximately the same thickness as the pull device 3, and reference numeral 5 designates a top-open tray that is fixed with screws 6 to the rear surface of the end plate 2.

The pull device 3 includes a longitudinal frame 7 that fits into a mounting hole 8 formed on the back side of the end plate 2, and a pull main body 10 that faces the front through a pull hole 9 formed on the front side of the end plate 2.
It consists of a pair of left and right supports 11, 11, and a front frame body 18 with a flange that fits into the inner periphery of the handle hole 9, and the mounting hole 8 and the handle hole 9 are both formed in a horizontally long oval shape. However, the horizontal dimension of the pull hole 9 is the same as the mounting hole 8.
shorter than that of

The pull main body 10 is disposed on the front surface of a longitudinal frame 7 having a U-shaped cross section and fitted from the back side of the mirror plate 2. The pull main body 10 is formed into a cylindrical shape with a substantially semicircular cross section, and the longitudinal side of the substantially semicylindrical portion Both ends in the direction are formed into a hemispherical shell shape. 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-shaped cross section, and both legs 11a, 11a of each support 11 are attached to the left and right sides of the longitudinal frame 7. The substrate 1 of the support 11 is configured to be removably inserted into guide grooves 14 formed along the longitudinal direction at both ends thereof.
A notch support groove 15 into which the rotating shaft portion 12 of the pull handle body 10 fits is formed in the free end edge of 1b.

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.

Engagement holes 17 are bored in the outer peripheral surface of the longitudinal frame 7 that fits into the mounting holes 8 on the back surface of the end plate 2 of the drawer 1 at appropriate positions in the longitudinal direction. On the other hand, the front frame 18 surrounding the inner circumferential surface of the handle hole 9 is fitted into the end plate 2 with its surface exposed, and the front end outer periphery of the front frame 18 has a collar 19 that can come into contact with the surface of the end plate 2. It is integrally formed. Further, the front frame body 18 is provided with a protruding pawl 20 that can be detachably engaged with the engagement hole 17 so as to be able to engage with the longitudinal frame body 7. Note that the engagement hole 17 may be provided in the front frame 18 and the protruding claw 20 may be provided in the longitudinal frame 7.

In this configuration, the pull main body 10 is disposed on the front surface of the longitudinal frame 7, and the supports 1 are disposed from both ends of the longitudinal frame 7.
1 and 11, the pull main body 10 is rotatably and non-removably attached via the support 11.

Then, by inserting the front frame 18 into the pull hole 9 from the front side of the end plate 2, and then inserting the longitudinal frame 7 together with the pull main body 10 from the back side, the mounting hole 8 on the front side of the end plate 2 is inserted into the handle hole 9. Since the length of the handle hole 9 is short, the pair of left and right supports 11, 11 attached to both left and right ends of the longitudinal frame 7 are not exposed to the surface side of the front plate 2a, and both the left and right supports The pull main body 10, which is rotatably supported via the handles 11 and 11, 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, so that it does not fall off forward. There is no.

Moreover, the longitudinal frame body 7 and the front frame body 18 are connected to the mirror plate 2.
Since they are engaged with each other while being sandwiched from the front and back, they will not fall off in either direction.

In this way, the pull device 3 can be easily attached to the inner circumferential surfaces of the attachment hole 8 and the pull hole 9 of the end plate 2 without any special work, and the attachment can be firmly performed.

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.
