Description

  The present invention relates to a faucet having a plurality of valve units that are spaced apart from each other, and more particularly, to a faucet in a form in which these valve bodies are fixed to a connecting bracket and connected by a connecting bracket.

  Conventionally, connecting pipe ends are connected to valve bodies of a plurality of valve units that are spaced apart from each other, and each valve unit is connected to each other via a connecting pipe, and each valve body is connected to a rigid connecting bracket. Faucets in a fixed and connected form are known.

FIG. 8 shows a specific example thereof.
In FIG. 8, reference numeral 200 denotes a temperature control valve unit, and a valve function unit for temperature adjustment is housed inside a metal valve body 202. In the upper part of the figure, a temperature adjustment operation unit 204 is provided.

Reference numeral 206 denotes a switching valve unit that is arranged separately from the temperature control valve unit 200. The water sent from the temperature control valve unit 200 is placed inside the metal valve body 208 on the side of the currant or shower head. A valve function part for switching the flow path is accommodated.
In addition, a switching handle 210 is provided at the top in the drawing.

  Reference numeral 212 denotes a metal connection pipe, one end of which is plugged into the valve body 202 of the temperature control valve unit 200 and the other end is plugged into the valve body 208 of the switching valve unit 206. The temperature control valve unit 200 and the switching valve unit 206 are in communication with each other via the connection pipe 212.

  Here, the connection between the valve bodies 202 and 206 and the connection pipe 212 is simply by inserting the connection pipe 212 into them, and the valve bodies 200 and 208 are removed from the connection pipe 212 as they are.

  Therefore, here, the valve bodies 202 and 208 are fixed to the metal rigid connection bracket 214 at the bottom by a small bolt 216 as a fastener, and the valve bodies 202 and 208 are connected by the connection bracket 214. This prevents the connection part from coming off.

  The connection bracket 214 also has a role of positioning the valve body 202 of the temperature control valve unit 200 and the valve body 208 of the switching valve unit 206 at positions separated by a set interval.

  In the case of the faucet of this form, in order to prevent the valve bodies 202 and 208 from coming off from the connection pipe 212, there is no particular need for a retaining member such as a cap nut or a retaining clip at the connection portion with the connection pipe 212. Therefore, there is an advantage that the problem of forgetting to attach the retaining member does not occur at the time of connection construction.

By the way, in this type of faucet, each valve body 202, 208 receives a force in a direction away from each other by the action of the supply water pressure introduced inside. Specifically, as shown in the schematic diagram of FIG. 9, an outward force due to the feed water pressure p is applied to a portion S of the valve body 202, 208 that faces the connection portion with the connection pipe 212.
Here, since the bottom of each valve body 202, 208 is firmly fixed to the connection bracket 214, the force is applied as a bending moment to each valve body 202, 208.

That is, a force is applied to the valve bodies 202 and 208 so as to tilt the valve bodies 202 and 208 in directions opposite to each other with the bottom portion, which is a fixed portion to the connection bracket 214 as a fulcrum.
At the same time, a force (load) is applied to the small bolt 216 and the connecting bracket 214 that fix the valve bodies 202 and 208.

  However, since the valve bodies 202 and 208 are made of metal and have high rigidity, such forces do not cause the valve bodies 202 and 208 to be deformed in a direction in which they fall down, and the load applied to the small bolts 216 and the like is small.

By the way, in recent years, the faucet has been made into a resin, and it has been proposed to make the valve body into a resin.
For example, Patent Document 1 below discloses that a valve body in a valve unit is made of resin.

  However, in the faucet having the structure shown in FIG. 8, when the valve body is made of resin, the resin valve body has a lower rigidity than that of a metal one. As indicated by an arrow F in the schematic diagram of FIG. 9, the valve bodies may be displaced with deformation in the direction in which they open to each other (the direction in which they fall).

  Thus, when such displacement occurs in the valve body, water leaks at the connection portion with the connecting pipe, or a large load is applied to the fasteners such as the valve body and small bolts, leading to a reduction in the service life of the parts. Problems arise.

  The following Patent Document 2 discloses a faucet in a form in which one end and the other end of a connection pipe are connected to each valve body of a pair of valve units. A connection nut is connected to one end and the other end of the connection pipe by a cap nut, and a stop member is attached to each of the connection portions.

  However, in the faucet disclosed in Patent Document 2, a stay is mounted across the pair of valve bodies, but this stay is intended to position the pair of valve bodies at a predetermined interval. Therefore, the mounting position is far from the position of the connecting portion with the connecting pipe, which is different from the present invention.

Effects and effects of the invention

  As described above, in the first aspect, the connection portion of the valve body with the connection pipe is defined at a position overlapping the internal flow path of the connection pipe (strictly, the internal flow path at the end of the connection pipe). The connection bracket is provided with a contact portion that abuts on the opposite outer surface in a planar shape and restricts displacement.

  According to the first aspect of the present invention, even if a force that pushes the side opposite to the connection portion of the valve body to the connection pipe works outward (in a direction away from the connection pipe) due to the action of the pressure inside the valve body, Since the contact portion that contacts the outer surface of the body opposite to the connection portion in a planar shape is provided on the connection bracket, even when the valve body is made of resin, the valve body is prevented by the displacement restricting action of the contact portion. It is possible to effectively prevent displacement with deformation in the outward direction, that is, the opening direction.

Therefore, according to the first aspect, even when the valve body is made of resin, water leakage is caused by the displacement accompanying the deformation of the valve body, the valve body is damaged, or the small bolt for fastening and fixing the valve body, etc. It is possible to solve the problem that a large load is applied to the fasteners and damage them, and the life of the parts can be extended.
The connecting bracket is made to be more rigid than the valve body. Normally this is made of metal.

In the first aspect, the contact portion may be in contact with an outer surface of a portion facing the connecting portion of the valve body (claim 2).
The portion facing the connecting portion is the portion that can most effectively regulate the displacement of the valve body. Therefore, according to claim 2, the displacement of the valve body in the opening direction, that is, the outward direction can be more effectively prevented. Can do.

  Next, a third aspect of the present invention is a valve body that is fastened and fixed to the connecting bracket by a fastener at a position that overlaps the internal flow path of the connecting pipe in a direction perpendicular to the inner flow path. Since the valve body is fastened and fixed to the connecting bracket at a position perpendicular to the same flow path that generates the pushing force in the direction, even if the valve body is made of resin, the valve body is the same as above. Can be effectively prevented from being displaced outwardly with deformation, and the same effects as described above can be obtained.

In this case, the fastening and fixing by the fastener may include fastening and fixing at a position opposite to the connecting portion on the side opposite to the connecting portion of the valve body with the connecting pipe (claim 4). .
The position facing the connecting portion is a position where the displacement of the valve body can be most effectively regulated, and the displacement of the valve body in the opening direction, that is, the outward direction can be more effectively prevented.

In this way, the part where force is applied to the valve body by the internal water supply pressure can be effectively restrained from the outside by the connecting bracket, and the valve body is deformed by the restraining action. Can be effectively regulated.

In this case, the fitting parts of the valve body and the connecting bracket can be formed in a planar polygonal shape (for example, a U shape).
By doing so, even when a force is applied to the valve body in the twisting direction (rotating direction around the axis), deformation due to the force can be effectively prevented.

In this case, the connecting bracket can be provided with a bent hook-shaped piece that hits the outer surface of the valve body in a planar shape along the surrounding portion (Claim 6).

Further, it is possible to more effectively prevent the valve bodies 36 and 38 from being displaced outwardly with deformation.

  In addition, the fastening with the small bolt 90 restricts the displacement of the valve bodies 36 and 38 most effectively, ie, the position opposite to the connection portion of the valve bodies 36 and 38 to the connection pipe 48, that is, the position opposite to the connection portion. Since it is also performed at a position opposite to the connecting portion, which is an obtained position, displacement in the opening direction of the valve bodies 36 and 38 can be more effectively prevented.

  Further, since the shape of the connection bracket 66 is formed so as to surround the fitting portion 52 of the valve body 36, 38, a portion to which force is applied to the valve body 36, 38 by the internal water supply pressure is added to the connection bracket 66. Therefore, it is possible to effectively restrain the valve bodies 36 and 38 from being twisted and other deformations by the restraining action.

The joint portion 52 can be brought into contact with each other, and the restraining action on the valve bodies 36 and 38 can be more effectively exhibited.

Although the embodiment of the present invention has been described in detail above, this is merely an example.
For example, in the present invention, it is possible to connect three valve units in a state of being surrounded by a connection bracket. At that time, deformation of the valve body of each valve unit is performed by the connection bracket, and further, The present invention can be configured in various forms without departing from the gist of the present invention, such as prevention by fixing with a coupling bracket with a fastener.
