Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an opening/closing device for opening and closing a tilt roof of a vehicle, a house, etc.

[Conventional technology]

As a tilt roof opening/closing device in which one end is rotatably connected to the opening edge and the other end can be opened and closed up and down, Japanese Patent Publication No. 56-21608 has a system in which cylindrical screw members arranged concentrically are operated by an operation knob. A device has been proposed in which the other end of the tilt roof is pushed up by rotating them and sequentially drawing them out. According to this, there is an advantage that the degree of opening of the tilt roof can be freely adjusted by appropriately rotating the operating knob, and that a large opening/closing stroke can be obtained with a device having a low overall height.

[Problem that the invention attempts to solve]

By the way, since the opening/closing device described above has a structure in which cylindrical screw members are paid out in sequence, it is necessary to rotate the operation knob many times to raise and lower the tilt roof to a desired position. In order to avoid this, if the screw pitch is increased, it is necessary to increase the frictional resistance of the screw or operating knob to prevent reverse rotation, and therefore a large operating force is required to rotate the operating knob.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a tilt roof opening/closing device with excellent operability that can quickly raise and lower the tilt roof with a small operating force.

[Means for solving problems]

In FIG. 1, a tilt roof G arranged to cover an opening B1 in the vehicle ceiling has one end rotatably connected to the edge of the opening (not shown), and the other end G1 can be opened and closed up and down as shown by the chain line in the diagram. It is as follows. A cylindrical housing 1 with a threaded portion formed on the inner periphery is erected on the opening edge B2 facing the other end G1, and a cylindrical body 2 with threaded portions formed on the inner and outer peripheries is disposed within the housing 1. It has been set up. The outer circumference threaded portion of the cylindrical body 2 is screwed into the threaded portion on the inner circumference of the housing.

A connecting member 3 is provided inside the cylindrical body 2, and a threaded portion formed on the outer periphery of the connecting member 3 is screwed onto an inner periphery threaded portion of the cylindrical body 2. It is fixed to the lower surface of end G1. The winding directions of the outer circumferential threaded portion and the inner circumferential threaded portion of the cylindrical body 2 are opposite to each other. On the other hand, the tip of an operating rod 4 having an operating knob 41 is inserted into the housing 1, and this is fitted into the cylindrical body 2 and rotates together with the cylindrical body 2, and is relatively movable in the axial direction. It is possible.

[action, effect]

When the operating rod 4 is rotated by the operating knob 41, the cylindrical body 2 rotates together with the operating rod 4, and is moved up and down within the housing 1 by screw connection. The connecting member 3 in the cylinder body 2, which rotates and moves up and down, is connected to the cylinder body 2 by a screw connection whose winding direction is opposite to the screw connection, so that it moves up and down in the same direction as the cylinder body.

As described above, in the opening/closing device of the present invention, since the concentrically arranged cylindrical body and the connecting member are raised and lowered simultaneously by the operating knob, the tilt roof can be opened and closed quickly with a small number of rotations of the operating knob. , and since there is no need to increase the screw pitch, there is no need to increase the frictional resistance to prevent reverse rotation, so the operating force of the operating knob may be small.

〔Example〕

In Fig. 1, a tilt roof G arranged to cover an opening B1 in the vehicle ceiling has one end rotatably connected to the edge of the opening (not shown), and the other end G1 provided with a weather strip. It can be opened and closed up and down as shown by the chain line in the figure. A cylindrical housing 1 is provided in the vertical direction on the concave opening edge B2 facing the other end G1.

The housing 1 consists of a cap part 11 (Fig. 2, 6) having a threaded part 11a formed on the outer periphery of the lower half, and a main body part 12 (Fig. 2, 7) having a threaded part 12a formed on the inner periphery of the upper end. Both threaded parts 11a,
12a, and are fixed thereto with the periphery of the attachment hole provided in the opening edge B2 sandwiched therebetween, as shown in FIG. A threaded portion 11b is formed on the inner periphery of the cap portion 11, while a stepped small diameter portion 121 is formed on the lower inner periphery of the main body portion 12.

A cylindrical body 2 is disposed within the housing 1. A threaded part 2a and a threaded part 2b are formed on the inner and outer peripheries of the cylindrical body 2, the winding directions of which are opposite to each other (FIG. 2 and 3), and the lower end thereof is connected to the bottom wall 2.
A through hole 211, which is closed at 1 and has a rectangular cross section, is provided in the center through which an operating rod, which will be described later, is inserted. The threaded portion 2b is screwed onto the threaded portion 11b of the cap portion 11, and when the cylinder 2 is rotated, it moves up and down within the housing 1.

A connecting member 3 is disposed within the cylindrical body 2.
The connecting member 3 is formed into a cylindrical shape, and a threaded portion 3a is formed on the outer periphery of the lower half thereof (FIG. 2), and the threaded portion 3a is screwed into the inner peripheral threaded portion 2a of the cylindrical body 2. The upper half of the connecting member 3 has protruding walls 31 facing each other at a predetermined interval, and a through hole 311 is provided through these protruding walls 31 . And the connecting member 3
is connected to a bracket 5 provided on the tilt roof G.

That is, the bracket 5 is fixed to the lower surface of the other end G1 of the tilt roof G by inserting bolts into mounting holes 51 (FIG. 2, 1) provided at both ends thereof, and has an extending portion extending downward from the center thereof. 52 to the above-mentioned projecting wall 31
A punch hole 52 provided in the extending portion 52 and located between
1 and the through hole 311, the two are connected at a variable connection angle.

An operating rod 4 is inserted into the housing 1. The operating rod 4 has a flange portion 42 protruding from its outer periphery.
(FIG. 2) is supported by the small diameter portion 121 of the main body 12, and its upper half 43, which has a rectangular cross section, is inserted into the through hole 211 of the cylinder 2. rotates around the axis of the operating rod 4, and is movable relative to each other in the axial direction.The lower half 44 of the operating rod 4 is cylindrical, and a serration is formed on its outer periphery. A screw hole 441 is provided in the center.The operating knob 41 is fitted into the lower half 44 in a recess 411 (FIG. 2, 5) provided at the center of the upper surface thereof. A screw inserted through the open through hole 412 is screwed and fixed into the screw hole 441.

In the opening/closing device having such a structure, the operation knob 41
When the operating rod 4 is rotated in the forward direction, the cylinder body 2 rotates together with it, and the winding direction is positive (for example, right-handed screw).
The threaded portion 2b and the threaded portion 11b are connected to each other so that the housing 1 can be moved upwardly. At this time, the connecting member 3 disposed inside the cylindrical body 2 that rotates upward also
The threaded part 3a and the threaded part 2a whose winding directions are opposite (for example, left-handed threaded) are connected to each other so that the threaded part 2a is raised inside the cylinder body 2,
The other end G1 of the tilt roof G is pushed up according to the amount of operation of the operation knob 41. When closing the tilt roof G, the operating knob 41 is reversely rotated to lower the cylinder 2 and the connecting member 3.

As described above, the opening/closing device of the present invention simultaneously operates the concentrically arranged cylindrical body serving as a screw member and the connecting member in accordance with the operation of the operating knob.
The tilt roof can be opened and closed quickly with a small number of rotations of the operation knob, and there is no need to increase the screw pitch, so the rotational operation force may be small.

It goes without saying that the device of the present invention can be used not only in the tilt roof of a vehicle but also in a house or the like.
