Abstract

To provide a snap-fit type valve which can be easily attached to and removed from a piping base member. A snap-fit type valve includes a pair of mounting levers on side surfaces of a valve body so as to engage with a base member in a snap-fit manner, wherein the mounting lever includes a shoulder which extends from the valve body, an arm connected to a distal end of the shoulder and an engaging section formed at a distal end of the arm, and is elastically deformable in a direction in which a distance between the engaging sections increases, a first mounting lever which is one of the pair has the shoulder and the arm connected to each other via an arch shaped connecting section and is formed to be elastically deformable at a position of the connecting section, and a second mounting lever which is the other of the pair is formed to be deformable at a position of the shoulder, and has an operation section to elastically deform the shoulder.

First claim

The invention claimed is:

1. A snap-fit type valve comprising:
a pair of mounting levers that allow a valve body in which a valve mechanism for opening and closing a fluid flow path is housed to be engaged with a piping base member in a snap-fit manner, wherein
the pair of mounting levers include shoulders which extend in opposite directions from a first side surface of the valve body and a second side surface which is opposite to the first side surface, arms which extend in the same direction parallel to each other from a distal end of the shoulders, and engaging sections formed on a distal end of the arms so as to engage with the base member, and each of the mounting levers is elastically deformable in a direction in which a distance between the engaging sections increases,
a first mounting lever which is one of the pair of mounting levers has the shoulder and the arm connected to each other via an arch shaped connecting section and is formed to be elastically deformable at least at a position of the connecting section,
a second mounting lever which is the other of the pair is formed to be deformable at a position of the shoulder, and has an operation section formed at a proximal end of the arm to protrude in a direction opposite to the arm so as to elastically deform the shoulder, and
the operation section is provided to only the second mounting lever, and the first mounting lever does not have the operation section.

2. The snap-fit type valve according to claim 1 , wherein
a thickness of the shoulder of the second mounting lever is smaller than a thickness of the arm and the operation section, and
a thickness of the shoulder, the connecting section and the arm of the first mounting lever is smaller than a thickness of the arm and the operation section of the second mounting lever.

3. The snap-fit type valve according to claim 1 , wherein, among the shoulder, the arm and the connecting section of the first mounting lever, a thickness of the arm and the connecting section are the same as each other, and a thickness of the shoulder is largest at a proximal end connected to the valve body, gradually decreases toward a distal end connected to the connecting section, and is the same as a thickness of the connecting section at the distal end.

4. The snap-fit type valve according to claim 2 , wherein, among the shoulder, the arm and the connecting section of the first mounting lever, the thickness of the arm and the connecting section are the same as each other, and the thickness of the shoulder is largest at a proximal end connected to the valve body, gradually decreases toward a distal end connected to the connecting section, and is the same as the thickness of the connecting section at the distal end.

5. The snap-fit type valve according to claim 2 , wherein the thickness of the shoulder of the second mounting lever is the same as the thickness of the arm and the connecting section of the first mounting lever.

6. The snap-fit type valve according to claim 3 , wherein a thickness of the shoulder of the second mounting lever is the same as the thickness of the arm and the connecting section of the first mounting lever.

7. The snap-fit type valve according to claim 4 , wherein the thickness of the shoulder of the second mounting lever is the same as the thickness of the arm and the connecting section of the first mounting lever.

8. The snap-fit type valve according to claim 1 , wherein a stopper which protrudes toward the valve body is formed at a distal end of the operation section of the second mounting lever, a finger hooking section which protrudes in a direction opposite to the stopper, and a protruding height of the finger hooking section is larger than a protruding height of the stopper.

9. The snap-fit type valve according to claim 1 , wherein tubular shaped ports are disposed on a bottom of the valve body so as to extend vertically to the bottom, and a length of the ports which protrudes from the bottom is the same as or larger than a length (n) of the arms of the mounting levers which protrudes from the bottom.
