Next, the operation of mounting the weather strip W using the apparatus 10 configured as described above will be described along with the operation and effect. As shown in FIG. 1, the mounting operation of the weather strip W is performed by inserting the weather strip W into the groove S formed in the weather strip W while fitting the flange portion F provided upright on the periphery of the opening of the door. It shall be performed by fitting and attaching to the periphery of the opening.

The weather strip W by the device 10
To carry out the mounting work, for example, first, the flange portion F
A part of the weather strip W is temporarily fitted to the flange portion F so that the groove 10 is fitted halfway into the groove S. In this state, the device 10 is set on the weather strip W. At this time, as shown in FIG. 1 and FIG.
The weatherstrip W is interposed in the groove 33a, 32b.

Then, the device 10 is moved along the flange portion F while holding the handle 14 and lightly pressing the weather strip W with the rollers 23 and the rollers 32a and 32b. During this movement, the switch 18 is turned on. Then, the air motor 40 is operated.

When the air motor 40 is operated in this manner, its rotational force is transmitted via the gear 42 to each of the gears 36a, 36a.
b, and the rotation of the gears 36a and 36b in this manner causes the second frame 24 to swing about the support shaft 20 as a fulcrum.

That is, each of the weights 38a and 36b has a weight 38 so that the phase difference between the gears 36a and 36b during rotation is 180 °.
Is fixed, when the gears 36a and 36b rotate synchronously in the same direction at the same speed, for example, as shown in FIG.
As shown in the figure, when the weight 38 of the left gear 36a is displaced upward from the lowest position (in the direction indicated by the arrow 50 in the figure), the weight 38 of the right gear 36b is moved downward from the highest position. Side (in the direction indicated by the arrow 52 in the figure), and at this time, the left end of the second frame 24 is moved upward by the inertial force due to the displacement of the left weight body 38. A force (a force in a direction indicated by an arrow 54 in the figure) acts on the right side of the second frame 24, and conversely, a downward force (a figure in the figure) is generated by the inertial force due to the displacement of the left weight body 38. , In the direction indicated by the arrow 56).
That is, when such a force acts on the second frame 24, the second frame 24 rotates clockwise (clockwise in the figure) around the support shaft 20.

On the other hand, as shown in FIG. 4B, when the weight 38 of the left gear 36a is displaced from the uppermost position to the lower position (indicated by an arrow 60 in the figure), the right gear 36a is displaced. 36
The weight 38 of b is displaced upward from the lowest position (indicated by an arrow 62 in the figure), and at this time,
A downward force (indicated by an arrow 64 in the figure) is applied to the left end of the second frame 24 by the inertial force due to the displacement of the left weight body 38.
On the other hand, an upward force (in the direction indicated by an arrow 66 in the figure) is applied to the right end of the second frame 24 by the inertial force due to the displacement of the right weight 38. Force) will act. That is, when such a force acts on the second frame 24, the second frame 24 rotates counterclockwise (counterclockwise in the figure) around the support shaft 20.

The direction of the force acting on the second frame 24 is alternately switched according to the rotation of the gears 36a and 36b, so that the second frame 24 swings about the support shaft 20 as a fulcrum. It will be.

When the second frame 24 swings in this manner, the rollers 32a and 32b disposed at both ends thereof are alternately pressed against the weather strip W. That is, since the rollers 32a and 32b are alternately pressed against the weather strip W with the roller 23 as a fulcrum, an appropriate vibration is given to the weather strip W, and as a result, the weather strip with respect to the flange portion F Will be promoted.

Therefore, according to the above-described apparatus 10, by moving the apparatus 10 along the weather strip W while pressing the roller 23 against the weather strip W with an appropriate force, the weather strip can be removed without a strong force. W can be appropriately mounted. In particular, in this type of conventional device in which the weather strip W is only pressed with a constant pressure, incomplete mounting may occur if the weather strip does not slide smoothly on a mounting portion such as a flange portion. However, according to the device 10, since the weather strip W is pressed while being vibrated as described above, the mounting of the weather strip W is effectively promoted even when the slip is poor as described above. . Therefore, the weather strip W can be mounted more appropriately than the conventional device.

The fitting and mounting device 10 is an embodiment of the fitting and mounting device according to the present invention, and the specific configuration thereof can be changed as appropriate without departing from the gist of the present invention. It is. For example, in the configuration of the above-described device 10, a device in which the roller 23 is omitted may be configured.
Even in this case, the second frame 24 includes the gears 36a and 36b.
Of the rollers 32a, 32b
Accordingly, vibration can be applied to the weather strip W while pressing the weather strip W, and the fitting and mounting of the weather strip W can be promoted.

In the apparatus 10, the rollers 32a,
Although the groove 33 serving as the engaging portion of the present application is formed only in the roller 32b, a similar groove is formed only in the roller 23, or a groove is formed in both the roller 23 and the rollers 32a and 32b. You may. In short, roller 23
The engaging portion as described above may be formed on at least one of the rollers a and the rollers 32a and 32b. Further, the shape of the engaging portion is not limited to the groove. For example, when a groove is formed on the surface of the weather strip W, the protrusion corresponding to the groove is engaged around the rollers 32a and 32b. It may be provided as a unit. In short, an engagement portion may be formed so that the rollers 23, 32a, 32b can be satisfactorily moved while being guided along the weather strip W. However, in particular, the roller 23 and the roller 32
In the case where proper work can be expected without providing the above-described engaging portions on the a and 32b, it is not always necessary to provide the above-mentioned engaging portions.

Further, in the above-described apparatus 10, the rotatable roller 23 and the roller 3 are used as the contact member and the pressing member of the present invention.
Although 2a and 32b are provided, the contact member and the pressing member do not necessarily need to be rotating bodies such as the rollers described above. However, if the contact member and the pressing member are formed of a rotating body, the device 10 can be smoothly moved while pressing the weather strip W, so that the workability is good, and the contact member and the pressing member are pressed. Another advantage is that damage to the weather strip W due to friction between the member and the weather strip W can be effectively prevented. Note that one of the contact member and the pressing member may be formed of a rotating body.

In the apparatus 10, the rotational drive is transmitted to the gears 36a and 36b via the gear 42. However, a belt transmission mechanism is provided to transmit the rotational drive of the air motor 40 to the gears 36a and 36b. May be configured. Further, an electric motor may be used instead of the air motor 40.

In the above embodiment, the present invention is applied to a device for mounting a weather strip W as an attachment member in an opening of a back door of a vehicle. However, the device is applied to a weather strip in another portion of the vehicle. It can also be applied, for example, is not limited to the mounting of the weather strip, for example, in the field of construction and the like, may be applied as a device for fitting and mounting an elongated seal member in the gap formed between the members. It can be used in various fields other than vehicle assembly.

[0041]

As described above, according to the present invention, a pair of pressing members are provided in the longitudinal direction of the mounting member, and the pressing members are advanced and retracted with respect to the mounting member so as to alternately press the pressing members against the mounting member. When the mounting member is fitted and mounted on the mounting portion, the mounting member is pressed by each pressing member, and the vibration is applied to the mounting member according to the operation of the driving unit. Since the fitting of the mounting member to the mounting portion is promoted, compared to a conventional device of this type which is configured to press the mounting member with a certain pressure to fit and mount the mounting member, It can be fitted and mounted to the mounting portion appropriately.

In particular, in the above-mentioned apparatus, if a contact member is provided between the pressing members and the driving means is constituted so as to swing the pressing member with the corresponding contact member as a support, the mounting can be more effectively performed. The attachment of the member can be promoted.

Further, the pressing member and the contact member are formed of a rotating body, and an engaging portion for guiding the pressing member and the contact member along the mounting member is formed around the pressing member and the contact member. By doing so, the device can be moved smoothly along the mounting member, thereby improving workability.
