Description

TECHNICAL FIELD The present invention relates to a flat handle used for a rack or cabinet for storing equipment such as a switchboard, a distribution board, a communication device, a server, etc., and particularly, a handle lever is capable of undulating and rotating with respect to a handle base fixed to a door. Regarding the plane handle.

This type of flat handle is disclosed in, for example, Japanese Patent Application Laid-Open No. 2004-187, in which a handle base fixed to a door panel and a handle shaft rotatably inserted into the handle base via a rotating shaft. The handle lever is mounted so that it can be undulated and rotated, and it is rotatably attached to the back side of the handle base via the handle shaft. When the door panel is opened and closed, the handle lever is raised from the handle base and rotated to engage and disengage the stopper plate.After closing the door panel, open the handle lever. It is a form to lay down on the handle base and store.

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

Therefore, the applicant of the present application has previously proposed, according to Patent Document 2, a flat handle in which the handle lever and the handle base are prevented from being meshed with each other and being damaged when the handle lever is rotated.
In the flat handle of Reference 2, a protective member made of an elastic synthetic resin is fixed to a portion of the flat handle 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 base when the handle lever is rotated. The protective member prevents the metal of the handle lever and the metal of the handle base from meshing with each other when the handle lever is rotated.
In this case, a fitting concave portion for receiving the protective member and an engaging projection for crimping the protective member are provided on the rear end side of the back surface of the handle lever, and the protective member has a convex portion that fits in the fitting concave portion, And a stepped engagement hole for press-fitting and crimping the engagement projection, and the front end of the rear surface of the handle lever so that the surface of the protection member forms an outer surface on the rear end of the handle lever. Mounted on the side.
With this configuration, when the handle lever is gripped and rotated, even if the handle lever is rotated while being pushed toward the handle base (falling direction), the surface of the elastic synthetic resin protective member is made of metal. Since it slides while being pressed against the surface of the handle base, the frictional resistance is small, the operation is performed smoothly, and there is no mutual engagement and damage.

Formed.
In this way, the handle lever 2 is attached to the handle shaft, which is rotatably inserted in the upper base end side of the handle base 1, so as to be capable of undulating and rotating with respect to the handle base 1 via the rotating shaft.

Thus, the handle base 1 and the handle lever 2 are configured, and in the flat handle H, the protection member mounting portion 4 is a portion facing the handle base 1 on the upper base end side of the handle lever 2, that is, as shown in FIG. , A narrow portion of the back surface of the handle lever 2 on the upper base end side, and particularly when the handle lever 2 is raised and lowered with respect to the handle base 1, the back surface of the handle lever 2 is the front surface of the handle base 1 (in this case, , An intermediate portion in the up-and-down direction that may slidably contact one side of the substantially U-shaped convex portion 131 on the front upper end side of the handle base 1, in this case, the shaft insertion portion 22 and the concave portion 221. The protective member 5 made of an elastic synthetic resin is attached to the protective member attaching portion 4 provided between the two.
As shown in FIG. 2, the protection member 5 is made of a synthetic resin material having excellent elasticity, flexibility, wear resistance, and slidability, and is formed in a size and shape that can be attached to the protection member attachment portion 4. .. The front surface of the protective member 5 is formed in an outer shape that is integral with the periphery of the protective member mounting portion 4, and a pair of locking claws 51 are symmetrically formed on the rear surface with the center of the rear surface as the center of symmetry. In the above, it is formed so as to be directed in the outer peripheral direction of the protective member 5 and has a generally L-shaped cross section. In this case, the protective member 5 is made of polyacetal and is formed in a horizontally long rectangle so that it can be attached to the protective member attachment portion 4. The front surface of the protection member 5 is formed to be flush with the rear surface of the handle lever 2 on the upper base end side, and a pair of locking claws 51 on the back surface are symmetrical with respect to the center of the back surface and have a substantially rectangular cross section. With the shape of (the cross-sectional shape in the direction perpendicular to the projecting direction of each locking claw 51 is substantially quadrangular), the tip is directed to the short side direction of the protective member 5 on the back surface of the protective member 5, and the sectional shape is generally L-shaped. Formed in. Further, in this case, on the back surface of the protection member 5, between the respective locking claws 5, in this case, at the central position in the longitudinal direction of the protection member 5, linear grooves are formed from one edge portion in the longitudinal direction to the other edge portion. 52 is formed so that the central position in the longitudinal direction of the protective member 5 is formed to be slightly thin, and the protective member 5 is formed at the position of the groove 52 so that the back surface of the protective member 5 is inward and can be bent and deformed into a substantially V shape. It
As shown in FIG. 3, the protection member mounting portion 4 has a mounting recess 40 that is long in the lateral direction so that the protection member 5 can be fitted between the shaft insertion portion 22 and the recess 221 on the rear upper surface base end side of the handle lever 2. A rectangular shape is formed, and a pair of engaging holes 41 elastically engages the locking claws 51 of the protection member 5 at positions corresponding to the locking claws 51 of the protection member 5 on the bottom portion 401 of the mounting recess 40. Engagement is possible, in this case, a hole having a square cross section that is slightly larger than the cross-sectional shape of each locking claw 51 (the cross-sectional shape perpendicular to the protruding direction of each locking claw 51) at each corresponding position on the bottom portion 401. 411 is bored toward the depth of the bottom portion 401 by the length of each locking claw 51, and the length of the protrusion of the locking claw 51 of each locking claw 51 is extended from the depth of the bottom part 401 toward each side 213 of the handle lever 2. In this case, a hole 412 longer than the above is formed by opening each side portion 213 to each side portion 213, and as a whole, a cross-section from each corresponding position of the bottom portion 401 of the protection member attachment portion 4 to each side portion 213 is substantially omitted. It is formed to extend in an L shape. In this case, each engagement hole 41 is assumed to be penetrated from the bottom portion 401 of the protective member attachment portion 4 to each side portion 213 and opened at each side portion 213, but each engagement hole 41 is formed from the bottom portion 401. The side portions 213 may be halfway to each side portion, and the side portions 213 may be closed without being opened. Further, in this case, the groove 401 of the protective member 5 is fitted at a position corresponding to the groove 52 on the back surface of the protective member 5 on the bottom portion 401 of the protective member mounting portion 4, that is, at the central position in the longitudinal direction of the protective member mounting portion 4. Possibly, a convex portion 402 is formed linearly from one edge portion in the longitudinal direction to the other edge portion, and when the protective member 5 is attached to the protective member attaching portion 4, the convex portion 402 is provided in the groove 52 of the protective member 5. It can be engaged.

FIG. 4 shows how to attach the protective member 5 to the protective member attaching portion 4.
As shown in FIG. 4, in the flat handle H, the tips of the pair of locking claws 51 are directed toward the outer peripheral direction of the protective member 5 on the back surface of the protective member 5, and in this case, in the short side direction of the protective member 5. A groove 52 is formed linearly between the locking claws 51 on the back surface of the protection member 5 so that the protection member 5 can be bent and deformed into a substantially V shape at the position of the groove 52. Therefore, when attaching the protection member 5, the protection member 5 is bent and deformed into a substantially V shape with the back surface inside at the position of the groove 52, and each locking claw 51 is tilted inward so that each locking The tip of the pawl 51 (the portion of the pawl) can be easily inserted into each engagement hole 41 of the protective member mounting portion 4, and if each locking pawl 51 is inserted into each engagement hole 41 and pushed in a little, With one touch, the tip of each locking claw 51 slides on the inner wall of the hole 411 of each engaging hole 41 and advances to the depth of the hole 411, and is locked to the wall surface of the hole 412 extending from that direction toward each side portion 213 for protection. The member 5 is fitted into the mounting recess 40 of the protective member mounting portion 4 and is mounted and fixed so as to be flush with the periphery of the protective member mounting portion 4.
Further, in this case, since the bottom portion 401 of the mounting recess 40 of the protective member mounting portion 4 is provided with the 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 is mounted on the protective member mounting portion 4. When the protective member 5 is attached to the portion 4, the groove 52 of the protective member 5 and the convex portion 402 of the protective member attaching 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 attaching portion 4. In a direction orthogonal to each other, in this case, the engagement 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 short side direction of the protective member 5, and the pair of locking Together with the claw 51, the protective member 5 is securely fixed by the protective member mounting portion 4.

The flat handle H has such a configuration, and as shown in FIG. 5, is attached to the door panel D by a mounting plate and a mounting screw via a waterproof packing, which is not particularly shown here.

FIG. 5 also shows the function and effect of the protection member 5 when the flat handle H is used.
When the door panel D is closed to the fixed frame body such as the box body, as shown in FIG. 5(1), the handle lever 2 is laid down on the handle base 1 and the lock unit 3 is locked by the key. Then, the handle lever 2 is locked. This locked state is displayed by the indicator i through the opening 20 at the lower tip side of the handle lever 2.
When the door panel D is opened from such a locked state of the door panel D, first, as shown in FIG. 5A, the key is first passed through the key hole 30 of the lock unit 3 and rotated in the unlocking direction. Then, the lock unit 3 is released. By unlocking the lock unit 3, the lock of the handle lever 2 is unlocked. This unlocked state is indicated by the indicator i through the opening 20 on the lower end side of the handle lever 2. Next, as shown in FIG. 5 (2 ), when the handle lever 2 is raised from the handle base 1, the curved leaf spring is pressed and deformed by the handle lever 2 at an arbitrary raising position of the handle lever 2 to cause the curved leaf plate to move. The handle lever 2 is held in this raising position by the reaction force generated in the spring. Then, from this state, the handle lever 2 is rotated in a predetermined opening direction. At this time, when the handle lever 2 is pushed toward the handle base 1 side and is slightly laid down, a part of the rear side of the handle lever 2 on the upper base end side, that is, the shaft insertion portion 22 on the upper rear side of the handle lever 2 is formed. The portion between the concave portion 221 and the upper base end side of the front surface of the handle base 1, that is, the one side portion of the substantially U-shaped convex portion 131 is in sliding contact. A protective member 5 made of an elastic synthetic resin is incorporated between the shaft insertion portion 22 and the recess 221 on the upper rear surface. The protective member 5 is made of a material excellent in elasticity, flexibility, wear resistance, and slidability. Since it is formed, the protective member 5 incorporated between the shaft insertion portion 22 and the recess 221 on the upper rear surface of the handle lever 2 and the one side portion of the substantially U-shaped convex portion 131 of the handle base 1 are provided. Contact with a small friction resistance and slide smoothly. Therefore, the metal of the handle lever 2 and the metal of the handle base 1 do not mesh with each other and are not damaged. Thus, when the handle lever 2 is rotated in the opening direction, the stopper plate is disengaged from the receiving portion on the fixed frame body side such as the box body. From this state, the door panel D is opened and the door panel D is opened.
When closing the door panel D again, after closing the door panel D, first, as shown in FIGS. 5(2) and 5(1), the handle lever 2 held at an arbitrary raising position is closed to a predetermined position. Turn in the direction. At this time as well, when the handle lever 2 is pushed toward the handle base 1 side and is slightly laid down, the portion between the shaft insertion portion 22 and the recess 221 in the upper rear portion of the handle lever 2 is in the upper front portion of the handle base 1. Although it is in sliding contact with one side of one side of the substantially U-shaped convex portion 131, the protective member 5 made of an elastic synthetic resin is installed between the shaft insertion portion 22 and the concave portion 221 on the upper rear surface of the handle lever 2. One side of the substantially U-shaped convex portion 131 of the handle base 1 comes into contact with one another with a small frictional resistance and slides smoothly, so that there is no meshing between the metal of the handle lever 2 and the metal of the handle base 1. No scratches. Thus, when the handle lever 2 is turned in the closing direction, the stopper plate is engaged with the receiving portion on the fixed frame body side such as the box body. Thereby, the door panel D is closed. Then, 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 leaning. The handle lever 2 is held in the 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. By locking the lock unit 3, the handle lever 2 is locked. This locked state is displayed by the indicator i through the opening 20 at the lower tip side of the handle lever 2.

As described above, according to the flat handle H, the handle base 1 and the handle lever 2 have the upper base end side of the handle lever 2 in either one of the opposing portions on the upper base end side. A protection member mounting portion 4 is provided on the end side facing the handle base 1, and a protection member 5 made of an elastic synthetic resin is mounted on the protection member mounting portion 4. The surface of the protection member 5 is protected by the protection member mounting portion 4. A pair of locking claws 51 projecting in a substantially L-shaped cross-section are provided on the back surface symmetrically with the center of the back surface as the center of symmetry, and the tips facing each other in the opposite direction as a whole. A pair of mounting recesses 40 are formed in the member mounting portion 4 so that the protection member 5 can be fitted therein, and the locking claws 51 of the protection member 5 are elastically engaged with the bottom portion 401 of the mounting recess 40 and extend in a substantially L-shaped cross section. Since the protective member 5 is attached to the protective member mounting portion 4 by the elastic engagement of the pair of locking claws 51 and the pair of engaging holes 41, the protective member 5 is made of elastic synthetic resin. By expanding 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 the flat handle H, a pair of locking claws 51 are formed on the back surface of the protection member 5 so as to face the outer peripheral direction of the protection member 5, and between the locking claws 51 on the back surface of the protection member 5. Since the groove 52 is formed linearly and the protective member 5 is formed so as to be bent and deformed into a substantially V shape at the position of the groove 52, when the protective member 5 is attached, the protective member 5 is substantially cut at the position of the groove 52. By bending and deforming it into a V shape, each locking claw 51 can be easily inserted into each engagement hole 41, and the protection member 5 can be more easily attached to the protection member attachment portion 4 with one touch. Further, in this case, since the linear convex portion 402 is provided in the bottom portion 401 of the mounting concave portion 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 protected by the protective member mounting portion.

It is formed. The front surface of the protective member 5 is formed in an outer shape that is integral with the periphery of the protective member mounting portion 4, and a pair of locking claws 51 are symmetrically formed on the rear surface with the center of the rear surface as the center of symmetry. In the above, it is formed so as to be directed in the outer peripheral direction of the protective member 5 and has a generally L-shaped cross section. When applied to the handle base 1 of the above-mentioned embodiment, the protection member 5 is formed in a vertically long rectangle so that it can be attached to the protection member attachment portion 4. The surface of the protective member 5 is on the upper base end side of the front surface of the handle base 1 (on one side of the substantially U-shaped convex portion 131 on the front upper base end side of the handle base 1 (that is, when the handle lever 2 is raised and raised). It is formed in a convex shape integral with the side on which the handle lever 2 contacts when it is moved)), and a pair of locking claws 51 on the back surface are symmetrical with respect to the center of the back surface, respectively, respectively The shape is substantially quadrangular (the cross-sectional shape in the direction perpendicular to the projecting direction of each locking claw 51 is quadrangular), and the tip end is directed to the short side direction of the protective member 5 on the back surface of the protective member 5, and the overall cross section is approximately L. It is shaped like a letter. Further, on the back surface of the protection member 5, a groove 52 is formed linearly between the respective locking claws 51, in this case, at the central position in the longitudinal direction of the protection member 5, from one edge portion in the longitudinal direction to the other edge portion. As a result, the central position in the longitudinal direction of the protective member 5 is formed to be slightly thin, and the protective member 5 is formed at the position of the groove 52 so that it can be bent and deformed into a substantially V shape. The protective member mounting portion 4 is also one side portion of one side of the substantially U-shaped convex portion 131 on the upper rear end side of the handle base 1 (that is, when the handle lever 2 is rotated upright). The mounting recess 40 is formed in a vertically long rectangular shape so that the protective member 5 can be fitted to the side portion (on the side where the handle lever 2 comes into contact), and each locking claw of the protective member 5 is formed at the bottom of the mounting recess 40. A pair of engagement holes 41 can elastically engage the respective locking claws 51 of the protection member 5 at positions corresponding to 51, and in this case, the cross-sectional shape of each locking claw 51 at each corresponding position of the bottom portion 401 ( A hole 411 having a quadrangular cross section, which is slightly larger than the cross-sectional shape in the direction perpendicular to the protruding direction of each locking claw 51, is bored toward the back of the bottom 401 by the length of each locking claw 51. A hole 412, which is longer than the protruding length of the claw of each locking claw 51, is bored from the inner side of the bottom part 401 in the vertical direction of the handle base 1, and as a whole from the corresponding position of the bottom part 401 of the protection member mounting part 4. It is formed so as to extend in a vertical direction in a substantially L-shaped cross section. Further, in this case, the bottom portion 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. Possibly, a convex portion 402 is formed linearly from one edge portion in the longitudinal direction to the other edge portion, and when the protective member 5 is attached to the protective member attaching portion 4, the convex portion 402 is provided in the groove 52 of the protective member 5. Engageable.
Even in this case, the same operational effects as those of the above embodiment can be obtained.

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 case where the handle lever 2 or the handle base 1 is provided with the protective member attachment portion 4 and the protective member 5 is attached has been described. However, the present invention is not limited to such a handle base and a handle lever, and the shape and structure of the handle base and the handle lever can be arbitrarily changed.
