Description

Devices with parallel gripping surfaces

technical field

The invention relates to a device with parallel gripping surfaces.

Background technique

A technical problem with existing gripping devices is that in their closed state the gripping surfaces cannot be kept parallel, or if parallel gripping surfaces are provided, the mechanical structure would necessarily be very complex.

Contents of the invention

Therefore, the purpose of the present invention is to provide a device to remedy the above-mentioned deficiencies in the prior art. In particular, the device should provide parallel gripping surfaces in a simple manner when gripping.

The above object is achieved by a device for grasping an object, the device has a first handle body and a second handle body, the first handle body and the second handle body are arranged at a first angle at a first end of the device. connected to each other, and the first handle and the second handle form a gripping region at a second end of the device opposite to the first end, so that mechanical pressure exerted by a user's finger on the handle of the device can be The object is grasped on the second end, wherein the first handle is designed as a multi-piece, the first part of the first handle is connected with the second part of the first handle through a rotating hinge, so that In the closed state of the device, parallel grip surfaces of the first and second handle are formed in the grip region.

The first handle is divided into a first part and a second part, and the first part can move relative to the second part along the rotating shaft. This "division" in the present invention can make the gripping surfaces of the first and second handle In the closed state they remain parallel to each other and the inclination of the handle ends relative to each other is compensated during the opening angle closing.

In addition, according to the invention, the first part and the second part of the first handle body can be designed to partially overlap, so that the relative movement of the first part and the second part of the first handle body around the rotation axis of the rotary joint is limited.

The advantage of this solution is that two defined end positions of the second part of the first handle can be provided. When the device is in the open state, the movement of the second part of the first handle around the axis is restricted by the first part of the first handle, and in the closed state for grasping, the movement of the second part of the first handle is restricted by the second part of the handle. to limit.

According to the invention, the second part of the first handle can also be divided into a first area and a second area, wherein the first area extends from the second end of the first handle to the axis of rotation of the rotary joint, and the second area The second area extends from the rotating shaft towards the first end of the first handle, so that at least a part of the first area of the second part of the first handle forms or can be formed together with the second end of the second handle. The gripping area is formed.

At this time, the second area of the second part of the first handle can be arranged to completely overlap the first part of the first handle, while the first area of the second part of the first handle does not overlap with the first area of the second handle or overlap only partially. It is also possible that the first region of the second portion of the first handle does not overlap or only partially overlaps with the first portion of the first handle.

The structure uses less material, so the invention has the special advantage of low production cost.

According to an embodiment of the present invention, the first handle body can have a top surface and a bottom surface opposite to the top surface of the second handle body, where the first region of the second part of the first handle body and the second The region has a top surface opposite to the bottom surface of the first portion of the first shank and a bottom surface opposite to the top surface of the second shank, wherein the top surface of the second region of the second portion of the first shank is in contact with the first shank A spring element, in particular a compression spring, is arranged between the undersides of the first part of the body, which is constructed and arranged to provide a spring force for spacing them apart. The function of the compression spring is to enable the device to have a regulated opening area when it is in the opened state, without having to be manually opened by the user.

In this case, the spring element can be designed to be connected to the bottom of the first part of the first handle, but not to the top of the second region of the second part of the first handle.

In addition, it can be provided that the second part of the first handle body has a larger—in particular the largest—as the top of the second part of the first handle body in the vicinity of the axis of rotation of the swivel joint or directly at the axis of rotation. The diameter is measured as the distance from the bottom surface to the bottom surface, and has a minimum diameter at each opposite end of the second part of the first shank, wherein the second part of the first shank is in particular triangular in shape.

Such a configuration allows optimal rotational movement of the second part about the axis of rotation while minimizing the overall height of the device itself.

According to the present invention, it can further be provided that the second part of the first handle body is formed with a convex part as a gripping surface on the second end, and in the closed state is formed by the gripping surface of the second handle body and the convex part. grip area.

This has the particular advantage that the contact surface of the gripping area is no longer limited by the geometry of the second part of the first handle itself due to the protrusion, and that the same forces are used when pressing the device It produces a particularly high grip force in the case.

The invention can finally provide that the first handle body and/or the second handle body comprise stainless steel and/or spring steel and/or are made of stainless steel and/or spring steel, the second region of the second part of the first handle body at the a second end of the first handle or in the region of the second end of the first handle and the second end of the second handle is opposite to the second end of the first handle, in particular to the second part of the first handle In the area opposite to the convex portion of the second part, at least partially on the bottom surface of the second part and the top surface of the second handle body are made of high-grade high-quality steel or hardened steel.

The invention also provides for the use of the inventive device as tweezers, in particular in the field of body care as tweezers.

The surprising finding on which the invention is based is that a device for gripping an object with parallel gripping regions can be realized with simple means. The device mainly consists of only 3 parts: two handles, which are connectable or connected to each other at a first end, wherein the first handle is in two parts. The two parts of the first handle are connected together by a rotary hinge so that when the two handles connected to each other at the first end are pressed together to close the grip area, the first The second part of the handle rotates to stop the inclination of the ends of each handle.

The two handles can be connected to each other at the first end by eg screws/bolts, wherein they are fastened to each other, in particular at a first corner, and can be gripped by pressing the handles together.

To achieve a high grip, the second part of the first handle has a protrusion on the second end of the device facing the second handle so that the force exerted by the user during compression is concentrated on the protrusion , instead of being dispersed on the entire circumference of the second part of the first handle body, so as to achieve a higher grip force.

The area of the device facing the second end, ie the gripping area, may be made of a stiff material or it may comprise the remaining area of the handle. This increases the durability of the device, since the gripping area is more stable, while at the same time no high force is required to press the device together.

Furthermore, it is also possible to design a fastening means at the first end of the device, for example in the form of a rope forming a loop. This rope is for example 130 mm long and includes a knot which is melted at high temperature so that it cannot be untied again. Such fastening means can prevent the device from falling damage. The knot itself can again be arranged in a small tube, for example 9 mm long and 6 mm in diameter, so that the knot cannot be caught by other objects.

According to an embodiment of the device, the device essentially comprises a first handle having a first part and a second part rotatably connected to the first part, a spring and a spring connecting the first and second handles together. connections and/or consist of these parts.
