Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a novel door handle device. More specifically, the present invention relates to a door handle device that can handle the handle and drive the latch mechanism of the lock box using elastic deformation of the handle itself.
[0002]
[Prior art]
The door handle device supports a handlebar extending in the vertical direction along the edge on the free side of the door so that the handlebar can be rotated, for example, around a vertical rotation axis, and the door is gripped by the handlebar. When the handlebar is pushed and pulled, the handlebar is rotated about a vertical rotation axis by the handle operation, so that the lock mechanism of the lock box is released by utilizing the relative rotation of the handlebar with respect to the door.
[0003]
In this way, the handle device is convenient because the latch mechanism can be released and the door can be opened and closed with a single handle bar.
[0004]
Alternatively, for example, in the handle device according to the invention disclosed in the specification of Japanese Patent Application No. 7-88783, a handle bar is attached to a door via a parallelogram link, and the handle bar is perpendicular to the door surface by deformation of the link. Guidance so that it can move forward and backward.
[0005]
Then, the movement of the handlebar in the front-rear direction when the handle is pushed and pulled in the direction to open or close the door is transmitted to the latch mechanism of the lock box via the linkage member, and this is released.
[0006]

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the drawings. The handle device according to the present invention is usually attached to both the outdoor side and the indoor side when it is provided on the door 10 as the doorway. However, when it is provided on the door of a storeroom or a warehouse, it may be attached only to the outer surface.
[0011]
In FIG. 1 to FIG. 3 showing the door handle device according to claim 1, reference numeral 2 denotes a handle bar made of a synthetic elastic material, and the handle bar 2 in the illustrated embodiment is along the edge on the free side of the door. Thus, it is a rod-shaped body that extends in the vertical direction and has a substantially arcuate shape as a whole.
[0012]
Here, the synthetic elastic material indicating the material of the handle bar 2 means an organic elastic material such as synthetic resin and synthetic rubber, and in some cases, a long core material may be embedded and used for reinforcement.
[0013]
One end (the lower end in FIGS. 1 to 3) of the inner and outer handlebars 2 and 2 formed in the same shape as the latch operation section 1 on the other end side for design reasons was vulcanized and bonded to the joint surface to the door 10. The mounting screws 4 and 4 passing through the substrate 3 are fixed to the door 10 so as to be called from the indoor side (left side in FIG. 1).
[0014]
On the other hand, the latch operation portion 1 is mounted on the door surface portion that is substantially aligned with the lock box 5 of the latch lock embedded in the door 10.
[0015]
The latch operating portion 1 is disposed above the one end of the handle bar 2 and is generally shaped like a slipper. That is, the main body portion 6 corresponding to a plate on which the foot of the slipper is placed and having an opening at the center is fixed by the mounting screws 4 and 4 so as to be called on the door surface.
[0016]
A hood portion 7 corresponding to an instep portion covering the tip of the slipper is integrally formed at the upper end portion of the main body portion 6, and the tip of the handle bar 2 is engaged with the hood portion 7. Yes.
[0017]
On the other hand, as shown in FIG. 1, in the latch operation section 1, a substantially T-shaped linkage member 8 and a substantially triangular drive lever 9 are integrally formed by a connecting pin 11 and a boss which is not numbered for the sake of clarity. A combined swing lever 12 having a generally hemispherical shape is attached.
[0018]
The swing lever 12 is fitted to the unnumbered boss at the center portion thereof, and is guided so as to be rotatable around the first pivot shaft 13 supported by the center opening portion of the main body portion 6.
[0019]
Further, the upper end of the swing lever 12 in FIG. 1, that is, the tip end portion of the drive lever 9 is engaged in a hollow portion 14 formed on the side of the upper end portion of the handle bar 2 facing the door 10.
[0020]
The upper end of the swing lever 12 passes through the upper end cavity 14 of the handle bar 2 and is linked to the upper end of the handle bar 2 by a second pivot parallel to the first pivot 13.
[0021]
In addition, in order to eliminate the twist between the swing lever 12 and the upper end of the handlebar 2 and to facilitate the operation of the link coupling portion between them, the diameter of the hole portion into which the second pivot 15 is fitted is slightly increased so-called. It is good to make a fool.
[0022]
In the door handle device according to the first aspect of the present invention having the above-described configuration, in the normal state where no external force acts on the handle bar 2, as shown in FIG. The surface opposite to the surface is elastically pressed against the edge of the opening of the outer surface of the main body portion 6 of the latch operation portion to define the position thereof.
[0023]
At this time, the linking member 8 is maintained at the angular position shown in FIG. 1, and at this time, the linking member does not contact the latch release member in the lock box 5.
[0024]
In FIG. 1, the right side is set to the outside, for example, and when a housewife who has returned from home grabs the handlebar 2 and pulls it in the direction of arrow A, for example, the handlebar 2 is elastically deformed and the upper end is outward. Move to.
[0025]
As a result, the swinging lever 12 linked to the upper end of the handle bar 2 rotates clockwise at a slight angle, and the inner end of the linkage member 8 engaged in the lock box 5 is the clock. The latch mechanism in the lock box 5 is released by rotating in the direction, that is, the direction of moving upward in FIG. 3, or the direction of arrow B in FIG.
[0026]
If the handle bar 2 is continuously pulled outward, the door 10 moves in the direction of arrow C in FIG. 1, that is, in the opening direction, so that the handle bar is pulled, for example, as in the case of a normal door handle device. By the operation, both the operation of pulling out the latch bolt from the strike plate and the opening of the door can be performed.
[0027]
When the handlebar 2 is pulled, as shown in FIG. 3, the outer surface of the upper end abuts the opening edge of the hood portion of the latch operation portion from the inside to define the maximum pulling amount of the handlebar 2.
[0028]
On the other hand, as described above, the minimum distance between the handle bar 2 and the door 10 is defined by the contact between the upper end of the handle bar 2 and the main body 6. Needless to say, this can be achieved by other means such as defining the rotation angle of the swing lever 12.
[0029]
On the other hand, although not shown in detail in FIG. 1, the inner handle device, that is, the left handle device is configured symmetrically with respect to that on the right side and the door 10.
[0030]
Further, the handlebar 12 in the inner handle device is normally biased outward as shown in FIG. 3 in a state where no external force is applied, and its upper end is locked to the hood portion 7. Yes.
[0031]
Furthermore, when going out, the inner handle bar 2 is pushed in the direction of arrow D in FIG.
[0032]
Therefore, when closing the door after passing through the door opening, after releasing the outer handlebar, move the inner handlebar to the indoor side, that is, the left handlebar 2 in FIG. At this time, since the swing lever 12 does not swing, the latch bolt is pushed into the lock box 5 by a wedge action acting between the slope and the strike plate.
[0033]
Since the operation when operating the handle device from the inside for going out is the same as described above, further detailed description is omitted.
[0034]
As is well known, the rigidity of the handle bar 2 is proportional to the cube of the dimension in the direction in which the external force acts.
[0035]
Therefore, if the cross-sectional shape of the handle bar 2 is, for example, substantially rectangular and the size in the direction of finding is larger than that in the prospective direction as in the illustrated embodiment, it is soft and elastically deformable in the front-rear direction. However, since it can be hardened in the left-right direction, the free end of the handlebar, that is, the other end can be smoothly smoothed by using a reasonable combination of the elasticity and rigidity of the handlebar 2 without using another guide device. Can be guided so as to move in the front-rear direction.
[0036]
On the other hand, the door handle device according to the second aspect of the present invention is configured as shown in FIGS. In these drawings, the portions denoted by the same reference numerals as those in FIGS. 1 to 3 are equal to each other.
[0037]
4 and 5, reference numeral 2 denotes a handle bar. One end (lower end) of the handle bar 2 is placed horizontally on a pedestal 16 formed in the same shape as the latch operating portion 1 at the other end for design reasons. The first support shaft 17 is supported so as to be swingable in the front-rear direction perpendicular to the surface of the door 10.
[0038]
The material of the handle bar 2 is a synthetic elastic material like the handle bar of the handle device according to the first aspect of the present invention.
[0039]
On the other hand, the material of the pedestal 16 may be the same as that of the handle bar 2 or may be other materials such as metal.
[0040]
On the other hand, the latch operation part 1 is restrained so that it can move only in the vertical direction and is mounted in a guided state on the door surface portion that is substantially aligned with the lock box 5 of the latch lock embedded in the door 10. .
[0041]
That is, the cross-sectional shape of the portion overlapping the latch operation portion 1 on the surface of the door 10 is substantially T-shaped in such a positional relationship as to be sandwiched between the latch operation portion 1 and the surface of the door 10 (FIG. 6). (See FIG. 7), an elongate (see FIG. 7) guide plate 18 extending in the vertical direction is mounted on the door surface by mounting screws 4 and 4.
[0042]
A latch operating portion 1 having the same shape as the pedestal 16 and having a groove of the same shape so as to fit the guide plate 18 from the outside is mounted on the guide plate 18 so as to be movable in the vertical direction. Has been.
[0043]
In this case, in order to prevent the latch operation unit 1 from slidingly contacting the door surface, it is possible to form a slight gap between the latch operation unit 1 and the door 10 as shown in FIG.
[0044]
In the central portion of the latch operation portion 1, a link member 8 having a substantially T-shape as a whole is integrally planted in such a positional relationship that the inner end is inserted into the latch mechanism portion of the lock box 5. Yes.
[0045]
Then, the inner end portion of the linking member 8 passes through a slit 18a (see FIG. 7) formed in the guide plate 18 for the convenience of assembly, and as shown in FIG. Has been inserted.
[0046]
Further, the other end portion (upper end in FIG. 1) of the handle bar 2 is connected to the latch operation portion 1 via a horizontal second support shaft 19 so as to be swingable in the front-rear direction.
[0047]
In this case, the handlebar 2 on the outdoor side (right side in FIG. 4) has a larger curvature than the illustrated curvature in the natural state, and is slightly extended when attached to the handle device. Shrinkage due to its own elasticity is prevented by the engagement between the inner end of the linkage member 8 and the edge of the slit 18a of the guide plate.
[0048]
It should be noted that the indoor side of the handle device is configured symmetrically in FIG. 4, but the handle bar 2 on the indoor side has a curvature shown in FIG. 4 in a natural state where no external force acts contrary to the outdoor side. It has a smaller curvature and tends to stretch due to its own elasticity when attached to the handle device.
[0049]
Therefore, the handlebar 2 on the indoor side has a curvature shown in FIG. 4 due to the engagement of the slit on the guide plate (not shown) mounted on the door surface symmetrically with the outer guide plate 18 and the connecting member on the indoor side. Keep.
[0050]
In the handle device having the above-described structure, when a housekeeper who has returned from home goes to open the door 10 and grasps the handle bar 2 and pushes it in the direction of the arrow F, for example, the entire handle bar 2 having one end fixed to the door 10 has a curvature. It elastically deforms in the decreasing direction, that is, in the extending direction, and the other end moves upward.
[0051]
Therefore, the linkage member 8 linked to the other end of the handle bar 2 via the second support shaft 19 and the latch operation portion 1 moves upward (not shown) in the lock box 5 to release the latch mechanism. .
[0052]
Thereafter, if the handle bar 2 is continuously pushed, the door 10 is opened by the movement of the handle bar 2 in the same manner as the handle device according to the first aspect of the present invention.
[0053]
On the contrary, in order to open the door from the indoor side, the handle bar 2 is pulled toward the indoor side, that is, pulled in the direction of arrow F in FIG.
[0054]
Then, the handle bar 2 is elastically deformed in the direction in which the curvature increases, and as a result, the linking member 8 moves downward, so that the movement is used to release the latch mechanism in the lock box.
[0055]
In FIG. 4, the handle bar 2 is linked to the pedestal 16 or the latch operating portion 1 through a slide having support shafts 17 and 19, and in this case, a reaction force due to a bending moment is generated in the slide portion. Therefore, the force applied to the handlebar 2 is efficiently used for elastic deformation of the handlebar 2.
[0056]
However, for example, if the handle bar 2 and the base 16 or the latch operating portion 1 are integrally formed of the same material and are combined so as to leave a skin between them so that the reaction force due to the bending moment is reduced. (Not shown), the connection by the support shafts 17 and 19 is not necessarily required.
[0057]
【The invention's effect】
As is apparent from the above description, the present invention guides the other end, which is the working end of the handlebar, by utilizing the elastic deformation of the handlebar 2, so that the guide device essential when the handlebar is a rigid body. The overall structure of the handle device can be simplified.
[0058]
For the same reason, not only can the maintenance and inspection of the handle device be omitted, but also the reliability of operation is greatly improved.
[0059]
Furthermore, since there is no play required for the handlebar guide device in the conventional handle device, the operation of the handlebar becomes smooth and the usability is improved.
