Description

TECHNICAL FIELD The present invention relates to a flat handle used for a switchboard, a distribution board, a communication device, a rack or a cabinet for storing equipment such as a server, or the like, and in particular, a handle lever can be raised and lowered with respect to a handle base fixed to a door. Regarding plane handles.

As disclosed in Patent Document 1, for example, this type of flat handle includes a handle base fixed to a door panel, and a handle shaft rotatably inserted through the handle base. A handle lever is attached to the back side of the handle base so that it can rotate up and down, and is rotatably attached to the back side of the handle base via a handle shaft. When the door panel is opened and closed, the handle lever is lifted from the handle base and rotated to engage and disengage the clasp from the receiver, and the handle lever is released after the door panel is closed. It is in the form of lodging and storing on the handle base.

By the way, in this type of flat handle, when the handle lever erected with respect to the handle base is rotated around the handle shaft, it is easy to apply force in the direction of pushing the handle lever toward the handle base. When the is rotated, the portion facing the handle base on the base end side of the handle lever engages with the handle base, and the strong metal-to-metal contact may damage both.

Therefore, the applicant of the present application has previously proposed a flat handle in Japanese Unexamined Patent Application Publication No. 2002-200325, which prevents the handle lever and the handle base from engaging with each other and being damaged when the handle lever is rotated.
In the flat handle of Document 2, a protective member made of elastic synthetic resin is fixed to a portion facing the handle base on the base end side of the handle lever so as to be interposed between the handle base and the handle lever when the handle lever is rotated. The protective member prevents metal meshing between the handle lever and the handle base when the handle lever is rotated.
In this case, a fitting recess for receiving the protective member and an engaging projection for crimping the protective member are provided on the base end side of the back surface of the handle lever, and the protective member includes a convex portion that fits into the fitting recess, and a stepped engagement hole for press-fitting and crimping the engaging projection, the surface of the protective member forming the outer surface of the handle lever on the proximal side of the back surface of the handle lever. mounted on the side.
By doing so, when the handle lever is gripped and rotated, even if the handle lever is rotated while being pushed toward the handle base side (in the direction of laying down), the surface of the elastic synthetic resin protection member will not be affected by the metal surface. Since they slide while being pressed against the surface of the handle base, the frictional resistance is small, the operation is performed smoothly, and they are not damaged by being engaged with each other.

Further, in this case, since the bottom portion 401 of the mounting recessed portion 40 of the protective member mounting portion 4 is provided with a linear convex portion 402 that can be fitted into the groove 52 on the back surface of the protective member 5, the protective member 5 can be easily mounted. When attached to the portion 4 , the groove 52 of the protective member 5 and the convex portion 402 of the protective member mounting portion 4 are engaged with each other, and the protective member 5 is fitted to the convex portion 402 and the groove 52 on the protective member mounting portion 4 . In this case, the engaging state between the tips of the pair of locking claws 51 and the pair of engaging holes 41 is maintained against the external force in the direction orthogonal to the protection member 5, in this case, in the direction of the short side of the protective member 5. The protective member 5 is securely fixed by the protective member mounting portion 4 together with the claw 51 .

The flat handle H has such a structure, and as shown in FIG. 5, it is attached to the door panel D by means of a mounting plate and mounting screws via a waterproof packing (not shown here).

FIG. 5 also shows the effects of the protective member 5 when the flat handle H is used.
When the door panel D is closed with respect to the fixed frame such as the box body, the handle lever 2 is laid down on the handle base 1 as shown in FIG. 5(1), and the lock unit 3 is locked by the key. and the handle lever 2 is locked. This locked state is indicated by an indicator i through an opening 20 on the lower tip side of the handle lever 2. As shown in FIG.
When the door panel D is to be opened from the locked state of the door panel D, as shown in FIG. to unlock the lock unit 3. By unlocking the lock unit 3, the handle lever 2 is unlocked. This unlocked state is indicated by an indicator i through an opening 20 on the lower tip side of the handle lever 2. As shown in FIG. Next, as shown in FIG. 5(2), when the handle lever 2 is raised from the handle base 1, the curved plate spring is pressed and deformed by the handle lever 2 at an arbitrary raised position of the handle lever 2 to form the curved plate. The handle lever 2 is held at this raised position by the reaction force generated in the spring. Subsequently, from this state, the handle lever 2 is turned in a predetermined opening direction. At this time, when the handle lever 2 is pushed toward the handle base 1 and slightly laid down, a part of the upper base end side of the back surface of the handle lever 2, that is, the shaft insertion portion 22 on the upper back surface of the handle lever 2, The portion between the concave portion 221 and the handle base 1 is in sliding contact with the upper base end side of the front surface of the handle base 1 , that is, one side portion of the substantially U-shaped convex portion 131 . A protective member 5 made of elastic synthetic resin is incorporated between the shaft insertion portion 22 and the recessed portion 221 on the upper part of the back surface. , one side of the substantially U-shaped convex portion 131 of the handle base 1 and the protective member 5 incorporated between the shaft insertion portion 22 and the concave portion 221 on the upper back surface of the handle lever 2 It contacts with small frictional resistance and slides smoothly. Therefore, the metal parts of the handle lever 2 and the handle base 1 are not meshed with each other and are not damaged. Thus, when the handle lever 2 is turned in the opening direction, the clasp is released from the receiving portion on the fixed frame side such as the box body. From this state, the door panel D is opened to open the door panel D.
When the door panel D is to be closed again, after the door panel D has been closed, first, as shown in FIGS. direction. At this time as well, when the handle lever 2 is pushed toward the handle base 1 and slightly laid down, the portion between the shaft insertion portion 22 and the concave portion 221 on the upper back surface of the handle lever 2 is pushed to the upper front portion of the handle base 1 . The protective member 5 made of elastic synthetic resin is incorporated between the shaft insertion portion 22 on the upper back surface of the handle lever 2 and the concave portion 221. Since one side of the substantially U-shaped convex portion 131 of the handle base 1 contacts with a small frictional resistance and slides smoothly, the metal of the handle lever 2 and the handle base 1 are not meshed with each other. Never scratch. Thus, when the handle lever 2 is turned in the closing direction, the clasp is engaged with the receiving portion on the side of the fixed frame such as the box body. The door panel D is thereby closed. Subsequently, as shown in FIG. 5(1), when the handle lever 2 is laid down on the handle base 1, the curved leaf spring is pressed and deformed by the handle lever 2, and the reaction force generated in the curved leaf spring causes the folding. The handle lever 2 is held in position. As a result, the closed state of the door panel D is maintained. Then, the key is passed through the key hole 30 of the lock unit 3 and rotated in the locking direction to lock the lock unit 3.例文帳に追加By locking the lock unit 3, the handle lever 2 is locked. This locked state is indicated by an indicator i through an opening 20 on the lower tip side of the handle lever 2. As shown in FIG.

By enlarging the mounting position of the protective member 5, the protective member 5 can be easily mounted at the mounting position of the protective member 5 at low cost.
Further, in this flat handle H, a pair of locking claws 51 are formed on the back surface of the protective member 5 so that their ends are directed toward the outer periphery of the protective member 5 , and between the locking claws 51 on the back surface of the protective member 5 . The groove 52 is formed in a straight line so that the protective member 5 can be bent and deformed into a substantially dogleg shape at the position of the groove 52, so that when the protective member 5 is attached, the protective member 5 is shortened at the position of the groove 52. By bending and deforming in the V shape, each locking claw 51 can be easily inserted into each engagement hole 41, and the protective member 5 can be more easily attached to the protective member mounting portion 4 with one touch. Further, in this case, since a straight convex portion 402 is provided on the bottom portion 401 of the mounting recess 40 of the protective member mounting portion 4 so as to be able to fit into the groove 52 on the back surface of the protective member 5, the protective member 5 is attached to the protective member mounting portion. 4, the engagement between the grooves 52 of the protective member 5 and the convex portions 402 of the protective member mounting portion 4 causes the protective member 5 to move against the convex portions 402 and grooves 52 on the protective member mounting portion 4. hold the engagement state between the pair of locking claws 51 and the pair of engaging holes 41 against the external force in the orthogonal direction, and together with the pair of locking claws 51, the protective member 5 is held by the protective member mounting portion 4. can be fixed securely.

In this embodiment, the tips of the pair of locking claws 51 are formed on the rear surface of the protective member 5 so as to face outward in the outer peripheral direction of the protective member 5.

It has a substantially rectangular shape (the cross-sectional shape in the direction perpendicular to the protruding direction of each locking claw 51 is a rectangular shape), and the tip thereof is directed in the short side direction of the protective member 5 on the back surface of the protective member 5, and the overall cross section is substantially L. formed into glyphs. Further, on the rear surface of the protective member 5, a groove 52 is formed linearly from one longitudinal edge to the other longitudinal edge of the protective member 5 between the locking claws 51, in this case, at the central position in the longitudinal direction of the protective member 5. As a result, the central position of the protective member 5 in the longitudinal direction is formed to be slightly thinner, and the protective member 5 is formed so as to be bent and deformable into a substantially dogleg shape at the position of the groove 52 . Similarly, the protective member mounting portion 4 is mounted on one side of the substantially U-shaped convex portion 131 on the base end side of the upper back surface of the handle base 1 (that is, when the handle lever 2 is rotated to stand up). A mounting recess 40 is formed in a vertically elongated rectangular shape so that the protection member 5 can be fitted in the side portion of the side that the handle lever 2 contacts, and the locking claws of the protection member 5 are formed at the bottom of the mounting recess 40 . A pair of engaging holes 41 at positions corresponding to 51 are elastically engageable with the locking claws 51 of the protective member 5. In this case, the cross-sectional shape of each locking claw 51 ( A hole 411 having a square cross section slightly larger than the sectional shape of each locking claw 51 perpendicular to the protruding direction thereof is drilled toward the bottom 401 by the length of each locking claw 51 . A hole 412 longer than the protruding length of each locking claw 51 is drilled from the back of the bottom portion 401 toward the vertical direction of the handle base 1 . It is formed so as to extend in the vertical direction so as to have a substantially L-shaped cross section. In this case, the bottom 401 of the protective member mounting portion 4 is fitted into the groove 52 of the protective member 5 at a position corresponding to the groove 52 on the back surface of the protective member 5, that is, at the central position in the longitudinal direction of the protective member mounting portion 4. A convex portion 402 is formed linearly from one longitudinal edge to the other longitudinal edge so that when the protective member 5 is attached to the protective member mounting portion 4, the groove 52 of the protective member 5 is fitted with the convex portion 402. Engageable.
Even in this way, it is possible to obtain the same effects as those of the above-described embodiment.

Further, in this embodiment, an example of the handle base 1 and the handle lever 2 of the flat handle H is shown, and the handle lever 2 or the handle base 1 is provided with the protective member mounting portion 4 and the protective member 5 is mounted. However, the present invention is not limited to such a handle base and handle lever, and the shape and structure of the handle base and handle lever can be arbitrarily changed. The size and depth, the cross-sectional shape, size and length of the pair of engaging holes 41, the outer shape, size and thickness of the protective member 5, the shape of the surface, the shape of the pair of locking claws 51 and the grooves 52 on the back surface, The size and the like are changed as appropriate according to the shape and structure of the handle base and handle lever.
