Description

Valve type hinge {A VALVED HINGE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge having a valve function, and more particularly, to a valve-type hinge that connects an upper water tank and a lower water tank to keep warm in a portable insulating chair.

The hinge is a rotating means between two objects, in particular the water tanks of the multipurpose warming chair according to the invention are constructed in a folding-type. This water tank consists of upper and lower water tanks and includes hinge means for connecting them.

Conventional hinge means performs a valve function for connecting or blocking the flow path from the upper water tank to the lower water tank, the principle of the gas valve was applied. Thus, when the upper water tank is folded in the lower water tank, the flow path is blocked and the flow path is opened when it is unfolded.

In addition, the hinge in the above manner has been used in the left and right both ends, there was a problem that the manufacturing cost increases, in essence, when the upper water tank is folded, the flow path is blocked so that the liquid inside the already heated water tank is not transferred to the upper or lower portion. There was a disadvantage of low thermal efficiency.

An object of the present invention to solve the above problems is to provide a valve-type hinge that the upper and lower water tanks are always open to maintain the flow path.

Another object of the present invention is to provide a valve-type hinge that constitutes a thermally efficient thermal chair by keeping the flow path at all times.

In order to achieve the above object, the present invention is a hinge having a valve function, the hollow valve having a flow path therein; At least one or more provided along the longitudinal direction on the outer surface of the hollow valve, the hermetic elastic member is provided with an elastic force in the outer circumferential direction; A packing groove for accommodating the hermetic elastic member on an outer circumferential surface of the hollow valve; And a pair of hinge members accommodating a part of the hollow valve and having a flow path connecting the upper water tank, the lower water tank, and the hollow valve, respectively.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, it should be noted that in the drawings, the same components or parts denote the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.

Figure 3 shows a valve type hinge according to an embodiment of the present invention. The first and second hinge members 10 and 20 have the same shape and will be described below with reference to one.

4 is a cross-sectional view of the valve-type hinge according to an embodiment of the present invention, the hinge member 10 is connected to the valve receiving portion 15 for receiving the hollow valve 30 and the upper or lower water tank It may be composed of a main body connecting portion 16 to. The valve accommodating part 15 may accommodate a part of the hollow valve 30, and the accommodated position may be accommodated until the hinge passage 11 inside the valve accommodating part 15. The hinge passage 11 may be connected to the valve receiving portion 15 to the main body connecting portion 16.

The hollow valve 30 is hollow so as to form the valve flow path 31 and preferably be cylindrical. Both ends of the hollow valve 30 may be accommodated in the valve receiving portions 15 and 25 in the first and second hinge members, respectively. The left and right surfaces of the hollow valve accommodated in the valve accommodating portion are provided with at least one or more along the longitudinal direction on the outer circumferential surface of the hollow valve to seal the oil flowing through the valve, and is provided with an elastic force in the outer circumferential direction. 33, a packing groove 32 can be formed on the hollow valve surface for this purpose. Preferably the hermetic elastic member may be made of rubber.

In addition, as shown in Fig. 5, the projection 34 having the same shape and size as the cross section of the valve accommodation portion is formed on the outer surface of the hollow valve in the center of the hollow valve. The protrusion may protrude in the circumferential direction to separate the first hinge member and the second hinge member. As the protrusion exists, the hollow valve can be accommodated in half of the valve receiving portion of each hinge member. The projection serves to prevent the leakage of the liquid flowing through the flow path by preventing the hollow valve is accommodated in the hinge member.

As a means for fixing the upper or lower water tank and the hinge, a method such as welding or pressure welding may be used to prevent leakage of liquids. Alternatively, the fixing groove 12 may be a main body of the hinge member. It may be provided in the connection portion. The fixing method may be conventional methods such as bolts or pivots.

Figure 6 shows a modified form of the hinge member in accordance with a preferred embodiment of the present invention, if the hollow valve is optionally received on the inner surface of the valve receiving portion of each hinge member separated in a predetermined position to be accommodated in half The members 14 and 24 can be formed. Preferably, the upper and lower portions of the inner surface may be formed as protrusions.

Figure 7 shows the elastic sealing members (13, 23) in the body connecting portion (16, 26) of the hinge member in accordance with a preferred embodiment of the present invention. The elastic sealing member may be located on the main body connecting portion of the surface of the hinge member and the main body contact portion and may serve to prevent the leakage of oil flowing through the flow path. Preferably the elastic sealing member may be made of rubber.

Figure 8 shows a modified form of the hinge member according to an embodiment of the present invention. The hinge member is inclined from one point of the surface in contact with the projection to the point of contact with the hollow valve, provided with a hermetic elastic member at the point of contact with the hollow valve, and washer between the hermetic elastic member and the protrusion for sealing. And an elastic body. This embodiment is to prevent the leakage of the liquid flowing in the flow path to the outside. The elastic body may be a coil spring, and the spring washer may be used without separately using the washer and the elastic body.

9 is a water tank for a warm chair provided with a valve-type hinge according to the present invention, the upper water tank 40 and the lower water tank 30 is connected by a valve-type hinge according to the present invention. Since the hollow valve is not fixed to each hinge valve, the upper and lower water tanks can be folded or expanded to serve as a hinge. In addition, the liquid contained in the upper or lower water tank may be moved to each other by the principle of heat transfer to the lower or upper water tank through the first and second hinge passage and the valve passage. Therefore, the valve-type hinge according to the present invention also serves as a connecting valve. Only one valve-type hinge according to the present invention may be connected to the upper and lower water tanks, and may be further installed.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

As described above, the valve-type hinge according to the embodiment of the present invention has the effect of maintaining the temperature of the entire water tank uniformly by lowering the manufacturing cost and always causing heat transfer by simultaneously performing the roles of the hinge and the valve. The valve-type hinge according to the present invention can be used particularly for portable thermal chairs used outdoors.
