Description

[Detailed description of the invention] This invention is a stand-alone device for the lid of a floor opening, and more specifically, the lid plate that opens and closes an opening formed on the floor surface, such as the opening of an under-floor storage compartment, is made to stand on its own in an open state. This invention relates to a lid self-supporting device.

Generally, in an underfloor storage, etc., it is necessary to keep a cover plate disposed in an opening formed in the floor in an open state. For this reason, in the past, an arm was pivotally attached to the side edge of the cover plate, and a claw piece provided at the tip of this arm was locked into a through hole in an opening frame provided at the opening in the floor. The arm was used to hold the cover plate by pulling it to prevent it from falling in the opening direction due to its own weight (see, for example, Japanese Utility Model Application No. 53-69125).

With this configuration, if a force is applied in the direction of closing the lid plate while the lid plate is open, the lid plate will topple over, so if an item is being put in or taken out of the opening, It is dangerous if something like this happens. Therefore, a configuration has been devised in which the distal end edge of the arm is brought into contact with the periphery of the through hole in the opening frame when the cover plate is open, thereby preventing the cover plate from easily closing. In this configuration, it is necessary to bias the arm with a spring means so that the tip edge of the arm moves upward and comes into contact with the periphery of the through hole when the cover plate is opened. When closing, the arm must be pushed down against the spring force.

As described above, when the structure is such that the lid plate is prevented from closing on its own, a problem arises in that the operation of closing the lid plate becomes troublesome. In particular, since the arms are generally provided on both sides of the cover plate, if you were to operate each arm separately, you would have to place both hands on both sides of the cover plate, making the operation difficult. There is a problem with bad sex.

The present invention aims to solve these problems by providing a lever that operates a pair of arms at the same time to improve operability when closing the lid plate. By forming a handle that protrudes in the direction, operation is facilitated, and furthermore, by housing the lever in a reinforcing bar fixed to the back of the lid plate,
The object of the present invention is to provide a self-standing device for a lid of a floor opening, which increases the strength of the lid plate by reinforcing bars and improves the appearance by hiding the lever.

The lid self-supporting device for the floor opening according to the present invention is
The aperture frame 3 is attached to the periphery of the aperture 2, and the aperture frame 3 is rotated with the rear edge remaining at the rear edge of the aperture frame 3, so that the aperture frame 3 can be rotated between a position where the aperture frame 3 is closed and a position where the aperture frame 3 is opened. The lid plate 4 can be opened and closed freely, and the general part is the lid plate 4.
A pair of holes 6 are rotatably attached to the side edges of the opening frame 3, and have a claw portion 5 formed at the other end thereof, and are vertically movably inserted into a pair of through holes 6 that penetrate vertically at both side edges of the opening frame 3. A lever 10 is slidably inserted into a long hole 9 formed along both side edges of the arm 7 and the cover plate 4, and presses the rear edge of each arm 7 in the front half of the sliding range.
and a spring means 11 for biasing the lever 10 toward the front of the cover plate 4. When the cover plate 4 is open, the claw piece 5 of the arm 7 is locked to the lower edge of the through hole 6. and a free position where the tip edge of the other end of the arm 7 is in contact with the opening edge of the through hole 6, and a free position where the tip edge of the other end of the arm 7 is inserted below the through hole 6. In the floor opening lid self-supporting device in which the arm 7 is swingable in conjunction with the back and forth movement of the lever 10 between the two sides, the lever 11 is disposed so as to straddle between both side edges of the lid plate 4. Both ends are inserted into the long holes 9 respectively, and a lever 11 is provided on the back surface of the cover plate 4.
A hollow reinforcing crosspiece 12 that accommodates almost the whole of is fixed,
The central portion of the lever 11 in the longitudinal direction projects forward from the reinforcing bar 12 on the back surface of the cover plate 4 to form a handle portion 13.

In the embodiments described below with reference to the drawings, an example of a device for making the cover plate of an underfloor storage stand on its own will be shown. 1st
As shown in the figure, an opening 2 is formed in the floor surface 1,
An opening frame 3 is attached along the periphery of the opening. A storage box 14 which is open at the top and whose opening edge matches the opening frame 3 is attached under the floor. As shown in FIG. 2, the opening frame 3 is placed on a frame bar 16 having a substantially L-shaped cross section and fixed to a back bar 15 provided on the back side of the periphery of the opening 2 on the floor surface 1. . The opening frame 3 is formed to have a substantially L-shaped cross section, and a flange portion 17 is formed at the upper end of the vertical piece to be secured to the floor surface 1. A through hole 6 is formed in the horizontal piece of the side edge of the opening frame 3, and a through hole 6 is formed to penetrate vertically, and a protrusion 18 is formed at the tip of the horizontal piece of the opening frame 3, projecting upward over the entire circumference. The cover plate 4 rotates with its rear edge remaining on the horizontal piece of the rear edge of the opening frame 3, and the peripheral edge of the cover plate 4 is placed on the horizontal piece of the opening frame 3, thereby closing the opening frame 3. . An arm 7 is attached to the side edge of the cover plate 4.
One end of the arm 7 is rotatably attached to the shaft, and the other end of the arm 7 is inserted into the through hole 6 formed in the opening frame 3 so as to be vertically movable. A claw piece 5 projects rearward from the other end of the arm 7. The lower edge of the claw piece 5 is arc-shaped, and the upper edge of the claw piece 5 is bent into an abbreviated shape. Two hollow reinforcing bars 12 are fixed to the back surface of the cover plate 4 along the left-right direction. A lever 10 is housed in a reinforcing bar 12 disposed on the rear end side of the cover plate 4, and both left and right ends of the lever 10 are inserted into elongated holes 9 formed on the side edges of the cover plate 4, and It is slidable within the hole 9. Further, the lever 10 is urged forward of the cover plate 4 by a spring means 11, as shown in FIG. That is, when the cover plate 4 is opened, the arm 7 moves upward within the through hole 6, and when the cover plate 4 is completely opened, the upper edge of the claw piece 5 is locked to the rear edge of the through hole 6. Ru. At this time, the lever 10 is moved to the front end position of the elongated hole 9 by the spring force of the spring means 11,
The lower edge of the claw piece 5 comes into contact with the front edge of the through hole 6. Further, the rear end edge of the cover plate 4 is locked to the protrusion 18 of the opening frame 3. Therefore, even if the cover plate 4 tries to fall backward in the open state, the rear end edge of the cover plate 4 and the protrusion 18 will not engage with each other, and the upper edge of the claw piece 5 and the rear edge of the through hole 6 will not engage with each other. The stop prevents the lid from falling backward, and the engagement between the front edge of the claw piece 5 and the front edge of the through hole 6 prevents it from falling forward, allowing the lid plate 4 to stand on its own in the open state. To close the cover plate 4, move the lever 10 to the rear end position of the elongated hole 9 and move the cover plate 4 forward. The engagement between the claw piece 5 and the periphery of the through hole 6 is released, and the arm 7 is closed.
can now move up and down in the through hole 6, and the cover plate 4 can be closed. By the way, in order to operate the lever 10 as described above, as shown in FIG. form. That is, by operating this handle portion 13, the lever 10 can be moved in the front-back direction, and by grasping the handle portion 13, the lid plate 4 can be opened and closed. In the figure, 20 is a reinforcing plate.

As mentioned above, the present invention has one end rotatably pivoted to the side edge of the cover plate, a claw piece formed at the other end, and a pair of through holes penetrating vertically on both sides of the opening frame. A pair of arms are inserted through the holder so that they can move up and down, and a lever that is slidably inserted into long holes formed along both sides of the lid plate and presses the rear edge of each arm in the first half of the sliding range. and spring means for biasing the lever toward the front of the cover plate, and when the cover plate is open, the claw piece of the arm is locked to the lower edge of the through hole, and the other end of the arm is engaged with the lower edge of the through hole. The arm moves in conjunction with the back and forth movement of the lever between a free position where the tip edge of the arm abuts the opening edge of the through hole and a free position where the tip edge of the other end of the arm is inserted below the hole. The lever is arranged to straddle between both edges of the cover plate, and both ends are inserted into the elongated holes. , the pair of arms can be operated simultaneously by levers, and the operability when closing the lid plate is greatly improved. In addition, the longitudinal center part of the lever protrudes forward from the reinforcing bar on the back of the lid plate to form a handle.
Since the handle portion protrudes in the direction of movement of the lever, it is only necessary to grasp the handle portion to operate the lever, thereby making it easier to close the lid plate. Furthermore, since almost the entire lever is housed within the reinforcing bar fixed to the back of the cover plate, not only is the cover plate reinforced, but the reinforcing bar that reinforces the cover plate can also be used to hide the lever. It has the advantage that it can be used for both purposes, the lever is not noticeable, and the appearance is improved.
