Definitions
- the present invention relates to balances, particularly balances with a double draft shield suitable for high-resolution balances.
- the air flow around the weighing pan such as the wind from an air conditioner, the breath of a person during weighing, the air flow generated when a person walks, etc.
- a windshield is provided to prevent it from acting as wind pressure and adversely affecting weighing.
- the windshield is usually provided with an opening for placing the sample to be weighed on the weighing pan, and is provided with a slide door for opening and closing the opening.
- an air flow also occurs when the slide door is opened and closed. After the slide door is closed, the air flow is attenuated while moving inside the windshield, but if it hits the weighing pan during this moving process, it adversely affects weighing, especially repeatability is deteriorated.
- a balance equipped with a double windshield in which another windshield is provided inside the windshield to cover the weighing pan.
- the inner and outer windshields each have a sliding door, so when weighing, it is necessary to open and close the sliding doors twice, one for the inner windshield and the other for the outer windshield, resulting in poor operability. be.
- the slide door of the inner windshield must be opened and closed by reaching out from the outside of the outer windshield, so the operability is extremely poor.
- Patent Document 1 a balance in which a detection means is provided to detect the opening/closing of a slide door that slides on the outside, and based on the detection result, the inner windshield is opened and closed in conjunction with the opening and closing of the slide door of the outer windshield.
- Patent Document 1 opens and closes the inner windshield by means of a motor upon detecting that the slide door of the outer windshield, which is opened and closed by hand, has been opened and closed.
- a rack and pinion gear are provided on the side wall of the inner windshield. Therefore, in the balance of Patent Document 1, the driving force transmission mechanism including the rack and pinion gear must be provided inside the double windshield, which is inconvenient in that the structure becomes complicated and the windshield also becomes large. .
- An object of the present invention is to provide a balance equipped with a double draft shield that eliminates these inconveniences.
- the balance with a double windshield comprises an inner windshield that covers the weighing pan and an outer windshield that covers the inner windshield, wherein the inner windshield and the outer windshield cover the inner windshield. has an openable and closable sliding door on the side surface, and a linkage mechanism for linking the sliding door of the inner windshield and the sliding door of the outer windshield so that the slide doors located on the same side move in the same direction. is provided.
- the sliding doors located on the same side of the inner windshield and the outer windshield are linked to move in the same direction, so opening and closing the outer windshield slide door can also open and close the inner windshield slide door at the same time.
- the linking mechanism is composed of a pair of engaging members that engage releasably, one of the engaging members is provided with a protrusion, and the other of the engaging members is provided with a recess.
- the projecting portion may be relatively displaced so that the projecting portion enters and exits the recessed portion, and the engaged state may be set when the projecting portion is inserted, and the disengaged state may be set when the retracted portion is set.
- the pair of engaging members can be engaged and disengaged by the projection and withdrawal motions of the protrusion with respect to the recess. They can be opened and closed simultaneously or can be opened and closed separately.
- the engaging member provided with the projecting portion has a housing, and the projecting portion is provided in the housing so as to be protrusible and to be positioned at two positions, a maximum projecting position and a maximum projecting position.
- the protrusion can be reliably displaced, and the protruding position in the engaged state and the plunge position in which the engaged state is disengaged can be reliably realized. can be performed reliably and easily.
- the engaging member provided with the concave portion has the concave portion provided at the tip end and an engaging lever provided with a return spring at the rear end which can be raised and lowered.
- the protruding portion may be retracted from the recess in a state where the engaging lever is raised against the elastic force of the return spring while the portion is projected into the recess.
- each engagement member in the engaged state of each engaging member, the rear end of the engaging lever is pushed down against the elastic force of the return spring, and the tip is raised to disengage the engaging members. Then, by releasing the depression and returning the engagement lever to the bent state by the elastic force of the return spring, each engagement member can be brought into the engagement state, and the engagement/disengagement operation can be performed reliably and easily. can be done.
- the sliding doors of the outer windshield and the inner windshield located on the same side are linked so as to move in the same direction. Since the slide door of the inner windshield can be opened and closed at the same time, the operation of opening and closing the slide door of the double windshield is easy. In addition, since the opening and closing operation of the double windshield slide door can be done only once at the same time, the opening time of the double windshield slide door is shortened, the amount of outside air flowing into the double windshield is reduced, and the weighing is performed. It is possible to improve the repeatability in the measurement, and in particular, to achieve accurate weighing in high-resolution balances.
