Description

[Detailed description of the invention] [Industrial field of application] The present invention is to install a horizontally opening article storage section for storing articles such as cords on the outer surface of furniture such as an office desk or a drafting desk along the horizontal direction. This invention relates to a support device for a lid that closes a horizontal opening in an article storage section when the lid is formed to extend directly.

[Conventional technology]

For office desks, etc., there is a storage section on the back of the desk to store the extra length of cords for electrical equipment used on the desk.
It is well known that the storage section is formed to extend linearly in the horizontal direction, and the opening of the storage section is closed with a lid that can be opened and closed.

In that case, as means for attaching a lid to the opening of the storage section to the storage section,
Japanese Patent Application Laid-open No. 61-240912 as a prior art proposes using a support body formed in a bifurcated shape in a plan view to detachably attach a lid body.

That is, in the prior art, longitudinally extending support shafts extending in the vertical direction are provided at both left and right ends of the opening in the storage section, while the left and right longitudinally extending support shafts are provided on the inner surfaces of the left and right sides of the lid relative to the opening. an elongated support formed into a bifurcated shape in plan view so as to be slidably fitted into the upper part of the support shaft in a direction perpendicular to the axis thereof; A short support body that is bifurcated in appearance is protruded, and with this short support body engaged with the vertical support shaft, the long support body located above is slid in the front and back direction while holding the vertical support shaft. By operating the lid body,
It is configured to rotate toward the rear of the desk around the short support at its lower end, thereby opening and closing the lid.

[The problem that the idea attempts to solve]

With the configuration of this prior art, the lid body can be easily removed from the desk, so for example,
As described in Japanese Utility Model Application Publication No. 60-109436, it has the advantage that the lid can be easily attached and detached compared to the case where the lid is attached to the desk via a hinge.

However, on the other hand, when opening the lid of the storage compartment, the lid must be slid back and forth in a state centered around the short support at the bottom end and the long support at the top sandwiching the vertical support shaft. In other words, each time the lid is opened or closed, the long support body is rubbed against the vertical support shaft, and the short support body is fitted onto the vertical support shaft. Since the long and short supports are pried apart, the durability of both the long and short supports is low, and rattling is likely to occur.

Moreover, in the prior art, the opening of the cord storage section is opened by tilting the lid backward toward the rear of the desk using the short support located below as a rotational fulcrum. However, since the short support is fitted over the vertical support shaft, it is not possible to tilt the short support over a certain angle with respect to the vertical support shaft. There was also the problem that the opening angle of the lid could not be increased beyond a certain angle because it could not be made longer than a certain value due to the depth dimension of the part.

The present invention provides a method for attaching a lid to an opening in an article storage section that opens sideways.
It is an object of the present invention to enable the lid to be opened and closed without reducing the durability of the support device for the lid, and to allow the lid to be opened wide.

[Means to solve the problem]

In order to achieve this objective, the present invention forms an opening in a storage section for cords, etc. provided in furniture such as a desk so as to extend horizontally on the side of the furniture, and this opening has a height A support shaft is disposed to extend horizontally at an approximately midway point in the width direction, and a lid for the opening is placed at an appropriate height between the upper end of the lid and the upper edge of the opening. a long support body disposed so as to form a gap of the same size and protruding from the inner surface of the lid body in a direction substantially perpendicular to the axis of the support shaft;
A short support having a short length is fixed at an appropriate distance in the axial direction of the support shaft, and the long support is slid on both upper and lower surfaces of the support shaft in a direction perpendicular to the axis of the support shaft. The support shaft is formed into a bifurcated shape in side view with a pair of upper and lower guide pieces movably in contact with each other, and the support shaft is removably and rotatably fitted into the base of the long support between the two guide pieces. The tips of both guide pieces are provided with locking protrusions that protrude inward from each other, and the support shaft is removably and rotatably fitted into the short support body. An engagement groove portion for engagement is provided,
Furthermore, a stopper portion is provided on the lower edge of the opening at a portion below the support shaft, with which the lower portion of the lid comes into contact.

[Functions and effects of the idea]

With this configuration, the opening of the storage section is closed with the lid (in this state, the support shaft fits into the engagement groove at the base of the long support and the engagement groove at the short support). ), a gap is formed between the upper end of the lid and the upper edge of the opening of the storage section, and the inner surface of the lid contacts the stopper at a portion below the support shaft. By touching the lid, the lid can be rotated about the support shaft so that the upper end thereof is tilted down or raised toward the inside of the storage part, and therefore the upper end of the lid is By pushing the part toward the inside of the storage part, the parts above and below the support shaft of the opening can be opened laterally, and by releasing the push of the upper end part of the lid, The lid body closes.

In other words, the normal opening and closing of the lid is done by rotating around the support shaft with the support shaft fitted into the engagement grooves in both the long and short supports provided on the inner surface of the lid. In other words, the long supports and short supports are not slid with respect to the support shaft along their protruding direction, so when opening and closing the lid, the long supports and short supports are This prevents undue twisting or abrasion due to sliding.

Also, by pulling the lid outward,
Since the support shaft is disengaged from the engagement grooves in the long support body and the short support body, the lid can be rotated around the axis of the support shaft with the support shaft being sandwiched between the guide pieces of the long support body. Because it rotates downward,
The opening of the storage section can be opened wide.

Furthermore, pulling the lid body with a stronger force,
The support shaft can be removed from the storage portion by pulling it out from between the upper and lower guide pieces of the long support over the retaining protrusions on both guide pieces.

In this way, the opening of the storage section can be set in a state where the upper and lower parts are partially open, a state where the lid is located below the opening and is wide open, and a state where the lid is removed. Three forms can be selected, and the opening form can be selected depending on the size and amount of articles to be stored in the article storage section.

Therefore, according to the present invention, although the lid for the opening of the storage section can be removed or opened wide depending on the case, the lid cannot be opened or closed normally. ,
This has the effect that it is possible to reliably prevent the durability of both the long and short supports for the lid from rapidly decreasing, and to provide a support device for the lid with excellent durability.
