Description

[Detailed explanation of the invention] Background of the invention (1) Technical field The present invention relates to a case used for transporting optical equipment, audio equipment, etc. The present invention relates to a case including a detachable third side plate hinged to one side plate.

(2) Prior Art and its Problems Conventionally, this type of case has been constructed with a handle provided on two hinged members. This handle has the disadvantage that when it is rotatably connected to the case body, it will fall down if you let go of it, making it difficult to hold when you try to hold it by passing your hand through the handle.

Purpose of the invention The present invention was devised in view of the above-mentioned prior art, and its purpose is to provide a case with a simple structure and a handle that does not easily fall over.

Structure of the invention The present invention that achieves the above object has the following structure.

That is, the case has first and second side plates 1 and 2 that are hinged together, and the first and second side plates 1 and 2 are hinged together.
Or two members 9 erected on the second side plate.
A handle 5 comprising a circular perforation 19 provided in the handle 5 and an engaging member 17 having a non-circular cross section that slidably engages with the circular hole 19 provided in the handle 5.
The handle is tilted to a predetermined angle with a small driving force, and is tilted beyond the angle with a driving force of a predetermined value or more.

Detailed Description and Effects of the Invention Hereinafter, embodiments of the invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of the case of this embodiment.

In the figure, reference numeral 1 denotes a first side plate, which is provided with a member 9 and a locking mechanism 6, which are erected so as to be slidably engaged with the handle 5. Reference numeral 2 denotes a second side plate, which includes an engaging portion that engages with a locking member 4 that is hinged to the third side plate 3, and a second side plate 2 that connects the third side plate 3 to the second side plate 2.
It is also provided with locking mechanisms 7 and 8 for integrally coupling and locking. The locking mechanism 7 can normally be operated from the outside of the case, but as will be described later, by operating the locking mechanism provided inside the case, it can be constructed so that it cannot be unlocked from the outside. It's summery.

FIG. 2 is a front view showing a state in which the third side plate 3 is locked to the second side plate 2, and the side plate 3 and the side plate 2 can be easily latched or unlatched by moving from side to side. A knob 10 is shown.

FIG. 3 is a perspective view showing the side plate 1 and the side plate 2 in an open state, and shows a locking mechanism 1 for locking and locking the side plate 2 and the side plate 3 from inside the case.
1, and a hinge member 20 that hingely connects the side plates 1 and 2.

FIG. 4a shows a locking member 4 hinged to the side plate 3 and an engaging member 15 provided in the side plate 2 and having a member 14 capable of engaging with an opening 16 of the locking member 4.
This shows that. A through hole 12 is provided in the flange portion 13 of the locking member 4 for hinge connection to the side plate 3.

Note that, as shown in FIG. 4b, which is a view taken along the line A--A in FIG. 4a, this member 4 protrudes upward from the engaging member 15 due to the elasticity of the material. Therefore, when a predetermined force is applied to this member 14 by the locking member 4, it is pushed downward, and the locking member 4
It is designed to release the engagement with the

FIG. 5 is a diagram showing the handle 5 in detail, and shows the handle 5 in detail.
As shown in the figure, a boss 17 is formed which slidably engages with a perforation 19 formed in a member 9 provided upright on the side plate 1. A protrusion 18 is formed on the boss 17, and when the boss 17 engages with a perforation 19 having a substantially circular cross section, the operating force for operating the handle 5 varies depending on the angle with respect to the side plate 1.
That is, the protrusion 18 and the perforation 19 are formed vertically from above the case.
The force required to tilt is small up to a predetermined angle where the protrusion 18 and the inner circumferential surface of the borehole 19 come into contact, and when the protrusion 18 and the inner circumferential surface of the borehole 19 begin to slide beyond this angle, the friction between them increases. The force required for tilting increases depending on the force. As a result, the handle 5 is normally always held in a nearly upright state, and prevents the handle from falling down when the user releases the case and making it difficult to grasp the handle when lifting the case.

With such a configuration, the side plate 3 is usually connected to the knob 1.
The side plate 3 is opened and closed by the 0 operation, and there is no risk of the side plate 3 falling off from the side plate 2 and being damaged by a large load at the time of opening. Further, since the side plate 3 can be locked from the inside of the case, there is no need to provide a special locking part for the side plate 3 on the outside, so that a case that is preferable in terms of design can be obtained.

Specific Effects of the Invention As described above, the present invention provides a case with a simple structure and a handle that does not easily fall over, and is extremely useful in practice.
