Publication number: 20240000061Abstract: A rodent trap (1) for catching and killing rodents, in particular mice and/or rats comprises clamp means (2) at least having an upper jaw part (3) and a lower jaw part (4). The upper jaw part (3) is able to swing relative to the lower jaw part (4) from an open position to a closed position in which it hits and kills a rodent. The upper jaw part is at least partially rotatable around a jaw rotational axis (Ajaw). A lifting lever (5) for releasing the clamp means (2) from the opened position is comprised. The lifting lever (5) is activatable by a rodent on the first side (f) of the jaw rotational axis (Ajaw). A force means enables the clamp means (2) to change from the open position into the closed position when released. The force means in particular is at least one spring. The lifting lever (5) comprises a latch means (7) on a latch side (LS) of the lifting lever (5) which is arranged on a second side (s) of the jaw rotational axis (Ajaw), opposite of the first side (f) of the jaw rotational axis (Ajaw).Type: ApplicationFiled: July 3, 2018Publication date: January 4, 2024Applicant: SWISSINNO SOLUTIONS AGInventors: Dennis WALSTAD, Silvin JANCIC

Publication number: 20220159940Abstract: An animal trap for killing an animal having a trap body and an electrical energy source. The electrical energy source is connected to a high voltage circuit. At least a first and a second, preferably a third, killing plate, wherein the first killing plate is connected to the high voltage circuit and the second killing plate is connected to the high voltage circuit are present. Preferably the third killing plate is connected to the first killing plate, such that in case an animal steps on the first and the second killing plate simultaneously the electric high voltage circuit is closed, and the animal is electrocuted. A shield, in particular a conductive shield, is arranged between the second killing plate and the trap body.Type: ApplicationFiled: March 25, 2019Publication date: May 26, 2022Applicant: SWISSINNO SOLUTIONS AGInventors: Dennis WALSTAD, Daniel ZUZULY

Publication number: 20140230312Abstract: The disclosure relates to a snap trap for small animals such as mice or rats, comprising a striking device which can be brought into a striking position and a standby position. The snap trap comprises a housing with a base and with an elongate inner compartment which is open at both longitudinal ends, at one longitudinal end of which an inlet opening leading to an, in particular tunnel-shaped, inlet section of the housing is arranged and at the other longitudinal end of which the striking device is arranged in a striking region of the housing. The disclosure is distinguished by the fact that the striking device is designed for at least partially closing an end opening of the inner compartment in the striking region of the housing and in particular completely closes the opening when the striking device is in the striking position.Type: ApplicationFiled: September 2, 2011Publication date: August 21, 2014Applicant: SWISSINNO SOLUTIONS AGInventors: Gabriel Le Laidier, Silvin Jancic, Dennis Walstad

Publication number: 20110271582Abstract: A snap trap (1) for mice has a pivotable bar (3), which is mounted on a base plate (2) and is prestressed in a readiness position against the spring force of a spring element (5), has a locking lever (6) for fixing the bar (3) in the readiness position and has a triggering part (4), which is provided with a bait holder (11). The triggering part (4) is mounted on the base plate (2) in the manner of a rocker. The triggering part (4) is also formed from plastic as a one-piece moulding.Type: ApplicationFiled: August 28, 2008Publication date: November 10, 2011Applicant: SWISSINNO SOLUTIONS AGInventors: Silvin Jancic, Dennis Walstad, Gabriel Le Laidier

Patent number: 7987628Abstract: An animal trap for catching mice has a box-shaped housing with foundation housing and attached to it is the cover housing, capable of swiveling. Arranged in the interior of the housing, there is a triggering system designed like a seesaw with a stepping platform. The cover housing is locked in the open position with the help of mechanical restraint devices. A locking mechanism resting in the cover housing has an unlocking button for restoring the open position, as well as an operating button for the user to transfer the cover housing into closed position.Type: GrantFiled: September 2, 2005Date of Patent: August 2, 2011Assignee: Swissinno Solutions AGInventors: Gabriel Le Laidier, Dennis Walstad, Silvin Jancic

Publication number: 20100031555Abstract: An animal trap (1) for catching voles dwelling in underground tunnels comprises a housing (2) provided with two openings (11). A closing part (3) which can be moved between a closed position and an open position is mounted in the housing and has a front edge (10) for applying a, preferably fatal, closing force to a vole, wherein the closing part (3) can be held in the open position under spring preloading by means of a retaining arrangement. The closing part (3) can be moved from the closed position into the open position such that on reaching the open position, the closed part (3) is automatically locked by way of the retaining arrangement, which is operatively connected to the triggering mechanism. When the vole enters the opening, the triggering mechanism activates to trigger the closing movement of the closing part (3).Type: ApplicationFiled: July 4, 2007Publication date: February 11, 2010Inventors: Gabriel Le Laidier, Dennis Walstad

Patent number: 5139051Abstract: Start up difficulties in gas compression systems due to undersized motors and/or low voltage conditions are avoided in a system including an electrically operated compressor (10, 36) including a compression chamber (34), a compressed gas reservoir (20) connected to the compression chamber (34) to receive gas therefrom, a pressure control switch (16) associated with the reservoir (20) and operable to control operation of the compressor (10, 36) in response to the pressure level of gas within the reservoir (20), and an unloader valve (42) connected to the compression chamber (34) and operable by the switch (16) by a valve construction including a valve body (50), an inlet (62) to the valve body (50) and in fluid communication with the compression chamber (34), and an outlet (68) from the valve body (50) to the ambient. A relatively large first passage (52) is located in the valve body (50) and extends between the inlet (62) and the outlet (68).Type: GrantFiled: July 1, 1991Date of Patent: August 18, 1992Assignee: Furnas Electric Co.Inventors: Dennis Walstad, Jean-Francois Couvreur
