  The present invention is based on the above situation, and when the male fitting portion is inserted into the female fitting portion and fitted, the rattling is caused by the fitting clearance between the male fitting portion and the female fitting portion. When the male fitting part is inserted, it is possible to solve the problem that the hand water discharge part is bent with respect to the support pipe part due to the fitting clearance, and the appearance is deteriorated. The present invention has been made for the purpose of providing a hose storage faucet that has a good insertion feeling and does not cause a large sliding resistance when the male fitting portion is inserted, and has a good insertion property and is easy to use.

Thus, according to the first aspect, the pull-out type hand water discharge portion on the distal end side having the water discharge port, to which a flexible hose is connected, is supported by the support tube portion on the proximal end side so as to be able to be put in and out. One of the hand water spouting portion and the support tube portion is provided with a male fitting portion that protrudes in the direction in which the hand water discharging portion is put in and out, and the other is provided with a corresponding female fitting portion, and these male fitting portions In the hose storage faucet adapted to hold the hand water spouting portion at the mating portion between the male mating portion and the female mating portion, the length of the male mating portion and the female mating portion in the direction in which the hand water spouting portion is put in and out An elastic fitting mechanism having an elastic body provided in a direction and elastically fitting the male fitting portion and the female fitting portion with elastic deformation of the elastic body. Ri disposed tare between the fitting portion between the front Symbol elastic member and the male fitting portion, the holder for holding the elastic body Tsu Oh interposed therebetween , Yes and elastic body on the outer peripheral surface of the holder is held, the holder may have no the overall tubular shape, the holder, the insertion guide during insertion into the female fitting portion of the male fitting portion It is characterized by forming a guiding member.

According to a second aspect of the present invention, in the first aspect , the holder is deformable in the direction of expansion and contraction, and the inner diameter is smaller than the outer diameter of the male fitting portion under the extracted state of the male fitting portion. It is characterized in that the elastic body is compressed and deformed by being pushed and expanded in the diameter increasing direction by inserting the male fitting portion into the female fitting portion.

According to a third aspect of the present invention, in the second aspect , the holder has a holding portion that holds and compressively deforms the elastic body, and a part of a portion located on a radially inner side of the elastic body is shaved. The cut portion is a cut portion, and the cut portion does not compress or deform the elastic body or reduces the amount of compressive deformation.

According to a fourth aspect of the present invention, the holder according to the second aspect is characterized in that the holder has a plurality of cut portions in a portion other than the holding portion that holds the elastic body .

Effects and effects of the invention

  As described above, the present invention has an elastic body provided in the longitudinal direction of the male fitting portion and the female fitting portion, and the male fitting portion and the female fitting portion are accompanied by elastic deformation of the elastic body. An elastic fitting mechanism for elastically fitting the two is arranged between the male fitting portion and the female fitting portion.

  According to the present invention, when inserting the male fitting portion into the female fitting portion and fitting them together, the elastic fitting mechanism causes the male fitting portion and the female fitting portion to move together with the elastic deformation of the elastic body. Due to the elastic fitting, it is possible to solve the problem of rattling caused by the fitting portion between the male fitting portion and the female fitting portion based on the fitting clearance as in the prior art. It is possible to solve the problem that the hand water spouting portion is bent in a discontinuous manner with respect to the support tube portion and deteriorates the appearance.

Moreover, in the present invention, the male fitting portion can be inserted into the female fitting portion flexibly with the elastic deformation of the elastic body, and the insertion feeling when inserting the male fitting portion can be made favorable, and thus the quality of the faucet The effect which can raise is also produced.
In addition, since the male fitting part and the female fitting part are elastically fitted by the elastic fitting mechanism in the fitted state, the male fitting part, that is, the hand water discharge part can be held with a desired holding force. In addition, the hand water spouting portion can be satisfactorily held at a desired rotational position.

In the present invention, an elastomer can be used as the elastic body .

In the present invention, a holder for holding the elastic body is interposed between the elastic body and the male fitting portion, and the elastic body is held on the outer peripheral surface of the holder.
In this way, the elastic body can be easily attached via the holder, and the male fitting portion can be prevented from directly contacting the elastic body when the male fitting portion is inserted into the female fitting portion. Therefore, it is possible to effectively prevent the elastic body from being worn or damaged by sliding the male fitting portion relative to the elastic body.
This effect is particularly great when an elastomer is used as the elastic body.
Here, the holder can be preferably made of resin.

Further, in the present invention, a holder Kakaru forms a cylindrical shape as a whole to the holder, which has form and guide member for the insertion guide during insertion into the female fitting portion of the male fitting portion, In this way, according The male fitting portion can be smoothly inserted into the female fitting portion under the guide action of the holder.

In this case, the holder can be deformed in the direction of expansion and contraction, and the inner diameter is smaller than the outer diameter of the male fitting part under the extracted state of the male fitting part. The elastic body can be compressed and deformed by being pushed and expanded in the diameter-expanding direction by insertion into the body (Claim 2 ).

Next, according to a third aspect of the present invention, a part of the holder holding part for compressing and deforming the elastic body and the part located on the radially inner side of the elastic body is a carved part from which the meat is cut. In the wall cutting part, the elastic body is not compressed and deformed (when the meat is cut through the holder) or the amount of compression deformation is reduced (when the meat is cut without penetration). is there.

  When an elastic body is generally compressed and deformed, for example, when a ring-shaped elastic body is compressed and deformed over the entire circumference, the deformation resistance of the elastic body may be larger than necessary. Thus, the insertion resistance when inserting the male fitting portion into the female fitting portion becomes larger than necessary, and the insertion workability may be deteriorated.

However, according to the third aspect of the present invention , since the shaving portion is provided in the holder and the elastic body cannot be compressed and deformed in the shaving portion or the amount of compressive deformation can be reduced, the insertion resistance due to the compressive deformation of the elastic body is larger than necessary. Sometimes, the insertion resistance of the male fitting portion based on the deformation resistance of the elastic body can be reduced, and the good insertion property of the male fitting portion can be ensured.

The cut portion of the holding portion in this holder also has a function of reducing the rigidity and deformation resistance of the holder itself.
It is desirable that the cylindrical holder has its own rigidity and deformation resistance as small as possible.
When the rigidity and deformation resistance of the holder are large, when the male fitting portion is inserted into the female fitting portion, the large deformation resistance due to the holder acts as a large insertion resistance for the insertion of the male fitting portion.

  In this case, if the holder is held in the diameter-enlarged shape for a long time by inserting the male fitting part, deterioration due to secular change is added to the irreversible permanent deformation due to stress, and the holder changes to the diameter-enlarged shape. Therefore, the insertion resistance when inserting the male fitting portion at the time of a new article and the insertion resistance when inserting the male fitting portion after a long period of time are different. That is, the insertion feeling when inserting the male fitting portion changes over time.

In order to prevent this as much as possible, it is desirable to reduce the rigidity and deformation resistance of the holder itself as much as possible.
Therefore, if the above-mentioned cut-off portion is provided in the holder holding portion, the rigidity and deformation resistance of the holder can be reduced, and the insertion feeling when inserting the male fitting portion can be held more constant over a long period of time. .

In this sense, it is desirable that the cut portion of the holding portion in the holder penetrates the holder in the thickness direction.
In this way, the amount of elastic deformation of the elastic body can be further reduced in the portion provided with the cut portion, and the insertion resistance when the male fitting portion is inserted due to the deformation resistance of the elastic body can be further reduced. In addition, it is possible to effectively reduce the deformation resistance of the holder itself .

Claim 4 of the holder, which has no parts other than the holding portion for holding the elastic member so as to cut the meat, according to the claim 4, the rigidity of the holder itself, is possible to reduce the deformation resistance it can.

In addition, it is desirable that the cylindrical holder has a shape divided in the circumferential direction, having a cut or notch over the entire length at a predetermined position in the circumferential direction.
By doing in this way, the deformation resistance at the time of a holder diameter-expanding deformation can be made small more effectively .

Next, the operation of this embodiment will be described below.
4 and 5 show a state in which the hand water discharger 20 is pulled out from the water discharge tube base 22, and from this state, the hand water discharger 20 is pushed into the water discharge tube base 22 side, and the female fitting portion of the hand water discharger 20 is shown. 48 and the male fitting portion 44 of the water discharge pipe base portion 22 are fitted together so that the hose 24 is entirely accommodated in the water discharge pipe base portion 22 and the hand water discharge portion 20 is supported by the water discharge pipe base portion 22. can do.

  In this case, specifically, when the male fitting portion 44 is inserted into the female fitting portion 48, the inner diameter of the male fitting portion 44 is outside the male fitting portion 44 in a state where the male fitting portion 44 is extracted from the female fitting portion 48. The resin holder 54 having a smaller diameter than the diameter is expanded in the diameter increasing direction while compressing and deforming the O-rings 52 and 53, and the male fitting portion 44 is inserted into the holder 54.

At this time, the holder 54 functions as a guide member for inserting the male fitting portion 44, and allows the male fitting portion 44 to be smoothly inserted into the female fitting portion 48.
At that time, the male fitting portion 44 is caused by a fitting contact action of the guide surface 96 of the holder 54 and further by a linear contact by the protrusion 94 formed linearly in the longitudinal direction on the inner peripheral surface of the holder 54. It is inserted into the holder 54 with little sliding resistance.

Further, since the holder 54 is a member that hardly has deformation resistance in the diameter expansion direction, when the male fitting portion 44 is inserted into the female fitting portion 48 via the holder 54, the insertion resistance is mainly O-ring. 52 and 53 are determined by the resistance to elastic deformation.
Further, the deformation resistance of the O-rings 52 and 53 is smaller in this embodiment than when they are uniformly compressed and deformed over the entire circumference.

This is because the O-rings 52 and 53 are not substantially compressed and deformed at the portions of the cut portions 78 and 80 provided on the holder 54.
For this reason, when inserting the male fitting portion 44 into the female fitting portion 48, the male fitting portion 44 is inserted into the female fitting portion 48 under appropriate insertion resistance, Can be fitted.

  When the male fitting portion 44 reaches the insertion end, the positioning projection 98 formed on the holder 54 as shown in FIG. 9 is elastically formed in the concave portion 100 on the outer peripheral surface of the male fitting portion 44. Then, the insertion amount of the male fitting portion 44 is defined, and at the same time, a click feeling due to the elastic fitting between the projection 98 and the concave portion 100 is generated.

  According to the present embodiment as described above, when the male fitting portion 44 is inserted into the female fitting portion 48 and they are fitted, the elastic fitting mechanism 50 is accompanied by the elastic deformation of the O-rings 52 and 53. In order to elastically fit the male fitting portion 44 and the female fitting portion 48, rattling occurs at the fitting portion between the male fitting portion 44 and the female fitting portion 48 based on the fitting clearance as in the prior art. In addition, the hand water discharger 20 can be prevented from being discontinuously bent with respect to the water discharge tube base 22 serving as a support tube because no fitting clearance is generated, and the appearance of the water discharge tube 16, that is, the faucet 10. The above appearance can be made good.

In addition, in this embodiment, the male fitting portion 44 can be inserted into the female fitting portion 48 with the elastic deformation of the O-rings 52 and 53, and the insertion feeling when the male fitting portion 44 is inserted can be made good. As a result, the quality of the faucet can be improved.
Moreover, since the male fitting part 44 and the female fitting part 48 will be in an elastic fitting state via the elastic fitting mechanism 50, the male fitting part 44, that is, the hand water discharging part 20 can be held with a desired holding force. In addition, the hand water discharger 20 can be favorably held at a desired position in the rotational direction.

  In addition, since the O-rings 52 and 53 are used as elastic bodies and are arranged at two positions spaced apart in the longitudinal direction, the male fitting portion 44 can be stably held and the cost required for the elastic body is low. Can be

  Furthermore, in this embodiment, the holder 54 is interposed between the O-rings 52 and 53 and the male fitting portion 44 so that the O-rings 52 and 53 are held on the outer peripheral surface of the holder 54. The O-rings 52 and 53 can be easily attached via the holder 54, and the male fitting portion 44 is directly attached to the O-rings 52 and 53 when the male fitting portion 44 is inserted into the female fitting portion 48. Therefore, it is possible to effectively prevent the O-rings 52 and 53 from being worn or damaged by sliding the male fitting portion 44 with respect to the O-rings 52 and 53.

  In the present embodiment, the holder 54 is formed into a cylindrical shape as a whole, and the holder 54 serves as a guide member that is inserted and guided when the male fitting portion 44 is inserted into the female fitting portion 48. The fitting portion 44 can be smoothly inserted into the female fitting portion 48.

  Further, in the present embodiment, the rigidity and deformation resistance of the holder 54 are made as small as possible by the cut portions 76, 78, 80 provided in the holder 54, and further by the notches 64 provided at predetermined positions in the circumferential direction. For this reason, the feeling of insertion when the male fitting portion 44 is inserted can be kept constant over a long period of time.

  In addition, in the present embodiment, a positioning protrusion 98 protruding radially inward is provided on the inner peripheral surface of the holder 54, and a corresponding positioning recess 100 is provided on the outer peripheral surface of the male fitting portion 44. Therefore, when the male fitting portion 44 is inserted into the female fitting portion 48, the insertion end of the male fitting portion 44 can be positioned by fitting the projection 98 for positioning and the concave portion 100. At the same time, the click feeling generated at that time can inform the user that the male fitting portion 44 has been inserted into the female fitting portion 48 to the set depth.

FIG. 10 shows a reference example .
In this example, the elastic body 102 is formed in a ring shape, and a thick portion 104 having a block-like thickness is arranged at regular intervals in the circumferential direction, and these are connected by a small-diameter connecting portion 106. is there.

By using such a ring-shaped elastic body 102, it is possible to reduce the deformation resistance force when the elastic body 102 is elastically compressed and deformed without providing the holders 54 with the above-described cut portions 78 and 80. Can do.
However, in terms of cost, it is inexpensive to partially compress and elastically deform the O-ring by the cut portions 78 and 80 of the holder 54 using the O-rings 52 and 53.

Although the embodiment of the present invention has been described in detail above, this is merely an example.
For example, in the present invention, instead of the O-ring as described above, a single elastic body such as a cylindrical rubber is used as the elastic body, and the male fitting portion 44 and the female fitting portion 48 are based on the compression deformation. Can be elastically fitted.
In the above embodiment, the male fitting portion 44 is provided on the side of the water discharge pipe base portion 22 and the female fitting portion 48 is provided on the side of the hand water discharge portion 20. It is also possible to provide a female fitting portion 48 on the water discharge portion 20 side and on the water discharge tube base portion 22 side.
