Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glass stopper mechanism for a door frame removable door, and relates to an automobile door in which a metal door frame is removably attached to a metal door body incorporating an elevating door glass. In order to prevent the door glass from inadvertently moving upward when the door frame is removed, the door glass is configured to automatically prevent the door glass from moving upward when the door frame is removed. Regarding.

For example, some four-wheel drive vehicles designed to be suitable for off-road driving have a canopy covering the cabin, a front window that can be folded forward, and a door frame that can be attached or removed. By removing the top, folding the front window forward, and removing the door frame, some cars become fully open cars with nothing separating the upper part of the cabin from the outside air.

As a method for making the above-mentioned automobile door into a door frame removable type, for example, as shown in Japanese Utility Model Application Publication No. 56-51622,
Conventionally, it has been known that a simple door frame consisting of a steel tube bent into an inverted U-shape and a canopy with a transparent window attached to the frame is removably attached to the lower metal door body. It is being However, with a door frame like this, which is just a hood stretched over the frame, it is impossible to attach a weather strip to the door frame to seal between the door opening and the door. There is a problem in that it is not possible to completely seal between the opening and the door. For this reason, in recent years, such automobile doors have been constructed in the form of a normal door, that is, a lower metal door body incorporates an elevating door glass, and a door frame slides and guides the door glass as it rises and lowers from the metal door body. Some models have emerged in which the door frame is detachable from the metal door body. In this case, it is not possible to attach the weather strip, which is a sealing member, to the outer periphery of the door frame.
This solves the problem of the conventional hood-type door frame mentioned above, that is, the problem of airtightness between the door and the door opening when the door frame is installed, and the metal door body has a raised and lowered door glass. Because it is installed, just raise and lower this door glass.
It becomes possible to open and close just the door window very easily.

However, the following new problems have been pointed out with this new type of door frame removable type door.

That is, when the door frame is removed, there is no member to guide and hold the door glass when it is raised, and therefore, if the door glass is carelessly moved up when the door frame is removed,
At this time, the door glass may shake, and sometimes,
This wobbling can cause damage to the wind regulator. That is, when the door frame is removed, it is preferable to keep the door glass housed within the metal door body and prevent it from rising.

The present invention was devised under the above circumstances, and its purpose is to provide an automobile door in which a door frame is removably attached to a metal door body equipped with an elevating door glass. A glass stopper that automatically operates to prevent the door glass from rising when the door frame is removed, and, conversely, automatically allows the door glass to rise when the door frame is attached to the metal door body. The object of the present invention is to provide a mechanism with an extremely simple configuration.

In order to achieve such an objective, the present invention:
The following technical measures have been taken:

Specifically, in an automobile door in which a door frame is removably attached to a metal door body incorporating an elevating type door glass, a guide rail for guiding and holding the door glass is provided inside the metal door body, and the lower end of the door frame is attached to the upper end of this guide rail. While the stopper member for the door glass is removably fitted, the stopper member for the door glass is moved between the lock position where it interferes with the vertical trajectory of the door glass at the upper end of the guide rail and the lock release position where it is retracted from this lock position. The stopper member has a stopper part that moves forward and backward on the vertical path of the door glass, and a door frame that is fitted to the guide rail, so that the stopper part moves toward the door. and a lock release actuating part that moves the glass stopper in a lock release direction where the door glass is retracted from the elevation trajectory of the door glass, and the stopper part is biased by a spring in a locking direction that advances onto the elevation trajectory of the door glass. It is characterized by the presence of

The above stopper member can be easily formed by bending a wire, for example.
When the extension of the leg of the door frame is inserted into the opening of the metal door body, that is, when the door frame is attached to the metal door body, the stopper member allows its lock release operating portion to be moved by the door frame. When pushed in the unlocking direction, the stopper takes a position where it does not interfere with the upward movement trajectory of the door glass. Therefore, at this time, the door glass can be opened and closed freely. On the other hand, when the door frame is removed from the metal door body, the stopper member is moved in the locking direction by the biasing force of the spring in conjunction with this movement, and the stopper member moves to the locking position where it interferes with the upward movement trajectory of the door glass. Take. When the stopper member assumes the lock position in this way, the stopper member is located so as to interfere with the rising locus of the door glass, so even if you try to raise the door glass, the top of the door glass will not be pulled by the stopper member. It hangs and cannot be raised. The glass stopper mechanism of the present invention automatically operates to prevent the door glass from moving upward when the removable door frame is removed. This completely prevents the door glass from accidentally moving up when removing it. Furthermore, since the door frame is automatically unlocked when attached, it is very easy to handle.

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 shows an example of an automobile having a door 1 with a removable door frame to which the present invention is applied.
This car is a four-wheel drive vehicle specifically designed to be able to travel off-road without any problems.
Most of the ceiling of the vehicle compartment and the side and rear portions of the cargo compartment are covered with a removable canopy 2, and the front window 3 can be folded forward as shown by the imaginary line. Further, the door 1 includes a metal door body 5 in which a door glass 4 that can be moved up and down is incorporated, and a door glass 4 that can be moved up and down.
A door frame 6 having a guide groove for slidingly guiding the door frame 6 is removably attached. Therefore, when the hood 2 is removed, the front window 3 is folded forward, and the door frame 6 of the door 5 is removed, this automobile has a roll bar 7 on the upper part of the vehicle body.
It turns into a fully convertible car with nothing to obstruct it, leaving behind only the front.

The door frame 6 of the door 1 shown in the drawings, as shown in FIG. The upper frame 9 has an almost gate-like shape, and has an upper frame 9 extending rearward from the upper end horizontally, and a rear leg 10 hanging almost vertically from the rear end of the upper frame 9.
As shown in a general cross section in FIG. 7, a concave groove 11 and a glass run 33 fitted therein are used to guide the door glass 4 moving upward and to hold the door glass 4 in the closed state. A weather strip 34 is attached to the outer circumferential surface of the door in close contact with the door opening to provide a seal between the door and the door opening. This door frame 6
The extension part 12 extending in the same direction as the rear leg is inserted into the opening 13 provided at the rear of the top of the metal door body 5 at the lower part of the rear leg 10, and the front leg 8 is inserted into the triangular part for attaching the door mirror. 1
It is attached to the metal door body 5 by fixing it to the top of the door body side fitting part 15 formed on the upper part of the metal door body 4 through a connecting member 16 fixed in advance to the lower part of the front leg 8 in a mating manner. It's becoming like that.

The glass stopper mechanism 17 of the present invention is assembled inside an opening 13 formed at the top of the rear part of the metal door body so as to insert the extension part 12 of the rear leg 10 of the door frame.

Details of an example of this glass stopper mechanism 17 are shown in FIGS. 3, 4, and 5.

As clearly shown in Figures 3 and 4,
At the top of the rear end of the metal door body 5, there are an outer panel 18, a rear side panel 19, and an inner panel 2.
An extension 1 of said rear leg 10 surrounded by 0
2 is formed, and the space inside this opening 13 has a substantially U-shaped cross section, in which the concave groove 11 of the extension part 12 fits on the outside and the door glass 4 fits and slides on the inside. A channel-shaped guide rail 21 has a back surface 22 connected to a side panel 19.
A spacer 35 is placed at a constant distance from the inner surface of the
has been fixed through. That is, this guide rail 21 cooperates with the outer surface thereof and the continuous inner surfaces of the inner panel 20, side panel 19, and outer panel 18 to form a U-shaped cross section for inserting and fitting the extension portion 12. It forms a holding space and also guides the vertical movement of the door glass 4 inside this channel.

Now, in the present invention, a stopper member 24 is provided which moves in conjunction with the attachment/detachment operation of the door frame between a lock position that interferes with the upward movement trajectory of the door glass 4 and an unlocked position that does not interfere with the upward movement trajectory of the door glass. It will be done.

As shown in FIG. 4, the stopper member 24 is located inside the guide rail 21, and the stopper member 24 is located at the top surface of the door glass 4 which is housed to the lowest position.
A stopper part 23 formed in an inverted U shape so as to be able to straddle the upper part of the vicinity of the end of a, and this stopper part 2
A pair of left and right support shafts 25 and 26 are formed by bending the lower ends of both legs 23a of the door frame 6 outward, and the support shafts 25 extend from the outer end of one of the support shafts 25 and are pushed by the extension 12 of the door frame 6 to be inserted. Lock release operating section 27
and a rotation restriction portion 28 extending from the outer end of the other support shaft portion 26 and abutting against the front edge 21a of the guide rail 21 to restrict the rotation end of the stopper member 24. By bending the wire,
Can be integrally molded. As clearly shown in FIG. 4, this stopper member 24 is attached to a notch-shaped support portion 29 formed at a portion of the front edge of the guide rail 21 that is a predetermined distance below the top end. It is supported by rotatably fitting the support shafts 25 and 26 and caulking the opening of the notch so that it does not slip out.
Further, this stopper member 24 is given a tendency to always rotate toward the lock side by a spring 30. The position indicated by the solid line in FIG. 4 is the lock position, and at this time the stopper portion 23 is positioned so as to straddle the upper part of the door glass 4 and protrudes on the upward movement trajectory of the door glass 4. cannot move upward. At this time, the lock release operating portion 27 is located at a position where it interferes with the locus of the extension portion 12 being inserted, and when the extension portion 12 is inserted,
Pushed by this, the stopper member 24 is moved by arrow U in FIG.
direction, and then rotate the stopper part 23 in the direction of the door glass 4.
It plays the role of displacing the lock to the unlock position that does not interfere with the upward movement trajectory of the lock.

The operation of the glass stopper mechanism 17 will be explained in more detail.

When the door frame 6 is removed,
As described above, the stopper member 24 automatically takes the lock position due to the elasticity of the spring 30, as shown by the solid line in FIG. 4, and prevents the door glass 4 from moving upward. Next, when the door frame 6 is installed, that is, the opening 13
When the extension part 12 of the rear leg is inserted into the rear leg, the lock release actuating part 27, which is in the locked position shown by the phantom line in FIG. As a result, the stopper portion 23 also rotates in the direction of the arrow U to assume a lock release position that does not interfere with the upward movement trajectory of the door glass 4. In this state, as shown in Figure 5,
The door glass 4 can be moved upward, that is, the door glass 4 can be opened and closed. Furthermore, when the extension part 12 is removed, the lock release actuating part 27
Since the force pushing the stopper member 24 in the direction of the arrow U is released, the stopper member 24 automatically rotates back in the direction of the arrow L due to the elasticity of the spring 30 and assumes the locked position. Also, at this time, the rotation regulating portion 28
1 and prevents the stopper member 24 from further rotating from the locked position.

Note that the door frame 6 is constructed by inserting the extension portion 12 of the rear leg 10 into the opening 13, and
It is fixed to the metal door body 5 by screws 31, and its front legs 8 are fixed as shown in FIG.
The connecting member 16, which has been fixed in advance to the lower end of the front leg 8 by welding or the like, is applied to the inside of the stationary front leg 15, and is fixed by screws 32, thereby attaching the connecting member 16.

As explained above, the glass stopper mechanism of the present invention is applied to an automobile door in which the door frame is removable from a metal door body incorporating an elevating door glass, and when the door frame is removed, the mechanism automatically stops. The door is locked to prevent the door glass from moving upward, and the lock is automatically released when the door frame is attached. Therefore, with the door frame removed, the door glass may inadvertently move upwards, causing it to wobble.
What happens when the glass regulator breaks?
Completely avoided. Moreover, since the present invention has an extremely simple structure, it is also very advantageous in terms of cost.

It goes without saying that the scope of the present invention is not limited to the embodiments shown in the drawings.

That is, in the illustrated example, the present invention is applied to the insertion portion of the rear leg of the door frame, but if possible, the front leg may be made into an insertion type and the present invention may be applied to this portion. Further, in the embodiment, the stopper member is formed of a single wire, but the stopper member is not limited to this.
