Description
SPECIFICATION
Construction unit comprising a gas spring
The present invention is directed to a construction unit comprising a first constructional member and a second constructional member which is movable with respect to the first constructional member. A gas spring is pivotally connected to the first and the second constructional member. The gas spring comprises a cylinder member having an axis and two end walls, namely a first end wall and a second end wall. A cavity is defined within the cylinder member. A piston rod member extends along the axis of the cylinder member through the first end wall inward and outward of the cavity. A piston unit is connected with the piston rod member within the cavity. A volume of pressurized gas fills at least part of the cavity.The gas spring is connected to at least one of the first and second constructional members by a pivotal joint unit having a joint axis substantially perpendicular to the axis of the cylinder member.
In known constructions of this type the pivotal joint unit comprises a pin fixed to the respective constructional member and an eyelet fixed to the respective part of the gas spring, namely the cylinder member or the piston rod member, this eyelet surrounding the pin and being fixed on the pin by nuts fixed to the pin. The installation of the gas spring within the construction of the chair is highly complicated in view of this type of pivotal joint unit.
It is further known in the art to provide pivotal joints between the gas spring and the respective constructional member, which are constructed as ball-and-socket joints.
It is a primary object of the present invention to avoid the disadvantages of the known types of pivotal joint units and to provide a pivotal joint unit which renders possible an easy assembling and disassembling even if the location of the pivotal joint unit is inaccessible.
A further object of the invention is to provide a pivotal joint unit which allows high forces to be transmitted both in the pressure and the pulling sense.
A further object of the invention is to provide a pivotal joint unit which allows considerable angular movability.
In accordance with the present invention the pivotal joint unit comprises a bolt member and a bolt receiving member having at least one recess receiving at least part of said bolt member, said recess having a cross-sectional area defined by a substantially U-shaped arc having two opposite legs and an opening, one of said bolt member and said bolt receiving member being connected to said gas spring, namely to one of said piston rod member and said cylinder member and the other of said bolt member and said bolt receiving member being connected to the respective constructional member.
In accordance with a preferred embodiment of the invention the legs defining the recess are positioned on diametrically opposite sides of the bolt member and the direction of the opening is substantially transverse to the axis of the cylinder member. With this embodiment the gas spring can be connected to the resprective constructional member by simply introducing the bolt member through the opening into the recess. As the direction of the opening is substantial!y transverse to the axis of the cylinder member, forces can be transmitted in the direction of the axis of the cylinder member without the risk of losing engagement between the bolt member the recess of the bolt receiving member.
In this preferred embodiment the recess in the bolt receiving member may be defined by a cylindrical bore having a mouth directed radially outward from the axis of the cylindrical bore. The diameter of the bore substantially corresponds to the diameter of a substantially cylindrical portion of the bolt member received by said bore.
In view of securing the engagement of the bolt member and the recess in the bolt receiving member, the width of the mouth may be smaller than the diameter of the cylindrical bore. In this case the cylindrical portion of the bolt member is provided with at least one key face permitting the cylindrical portion to pass through the mouth only in at least one predetermined angular position of the gas spring with respect to the respective constructional member. The key surface may be parallel to the joint axis. With this embodiment the installation is established in a simple way by bringing the gas spring into that angular position, in which the bolt member can enter through the mouth into the cylindrical bore, whereupon the gas spring is pivoted with respect to the construction into the operational position.Hereupon, the other end of the gas spring may be connected to the respective other constructional member.
In view of transmitting considerable forces in the direction of the axis of the cylinder member, the key face is substantially parallel to the axis of the cylinder member.
The bolt member may comprise two cylindrical end portions to be received by two respective recesses of the bolt receiving member and a middle portion fastened to the piston rod member. In this case the bolt receiving member is fixed to the respective constructional member. In view of connecting said middle portion and said piston rod member, the piston rod member may have an outer end portion inserted into a socket provided in the middle portion.
In view of exactly defining the position of the piston rod member with respect to the bolt member, a snap ring may be provided in a circumferential groove of the piston rod memberadjacentthe outer end thereof, said snap ring engaging an abutment face of the bolt member adjacent the socket. It is to be noted that an exact positioning of the piston rod member with resepct to the bolt member is of particular importance, if the gas spring is a lockable gas spring, in which two working chambers are defined by the piston unit within the cavity, these two working chambers are interconnected by a passage, a valve is provided in the piston unit for closing and opening said passage and a valve control rod is guided through a bore of the piston rod memberforcontrolling opening and closing of the valve.In this case actuating means are provided for actuating the outer end of the control rod projecting beyond the outer end of the piston rod member. In view of exact cooperation of said actuating means and said control rod, it is necessary to exactly adjust the position of the piston rod member with respect to the bolt member.
Both possibilities are considered by this invention, the possibility of fastening the bolt member to the gas spring and the bolt receiving member to the respective constructional member, and also the other possibility of fixing the bolt receiving member to the gas spring and the bolt member to the respective constructional member.
As the above described constructional solution with a key face on the bolt member requires a considerable angular movability of the gas spring on installation of the gas spring within the construction, e.g. a chair, a further construction is also considered, in which the mouth has a width substantially corresponding to the diameter of the cylindrical bore and securing means are provided for securing engagement of the bolt member and the bolt receiving member. In this case the securing means can be applied after the bolt member has been brought into engagement with the bolt receiving member, so that the gas spring can be installed into the construction in any angular position with respect to the construction.If the bolt member has extensions in both axial directions thereof beyond the bolt receiving member, the securing means may comprise two pairs of fork arms, each of said pairs of fork arms engaging respective extensions of the bolt member adjacent the bolt receiving member. The pairs of fork arms are interconnected by interconnecting means and the interconnecting means may be provided with fastening means for fastening the securing means to the bolt receiving member. In view of an easy assembling, the fastening means may be in snapping engagement with the bolt receiving member. The fork arms may be provided with recesses shaped for engagement with the extensions of the bolt member.
According to a further less preferred embodiment the bolt member extends in the axial direction between the legs of the U-shaped recess. The bolt member is provided with axial bores at both axial ends and bearing pins mounted to said legs engage the axial bores. The bearing pins may be fixed to the bolt receiving member by thread means or rr.a m;be pressfitted into the bolt receiving member.
Further objects and advantages of the invention will be apparent from the following description of an exemplary embodiment thereof, taken in conjunction with the accompanying drawings, in which:
Figure 1 is a side view of a chair construction of this invention partly in section;
Figure 2 is a top view of Figure 1;
Figure 3 is the end of a piston rod member connected with a bolt member to be received by a bolt receiving member;
Figure 4 is a side view of the bolt receiving member with the bolt member of Figure 3 inserted therein;
Figure 5 is a top view on the bolt receiving member and the bolt member with a further embodiment of this invention;
Figure 6 is a section through a further embodiment of a pivotal joint unit of this invention;
Figure 7 is a bottom view of the pivot joint unit of
Figure 6; and
Figure 8 is a side view of the pivotal joint unit of
Figures 6 and 7.
In Figure 1 a seat support member is designated by 10. This seat support member 10 is mounted to the upper end of a chair column 12, which may comprise a gas spring for heat adjustment of the seat support member 10. This gas spring (not shown) is controllable by a control lever indicated at 14.
A back rest member 16 is pivotally mounted on the seat support member 10 about a pivot pin 18. A seat plo-'te 20 is releasably fixed to the seat support member 10.
A gas spring 16 extends between the back rest member 16 and the seat support member 10. The gas spring 22 comprises a cyiinder member 24 with a cavity 26 defined therein. A piston rod 28 extends inward and outward of the cavity 26. The cavity 26 is filled with a pressurized gas. A piston 30 is fixed to the inner end of the piston rod 28. The cavity 26 is divided by the piston 30 in two working chambers 26a and 26b. The two working chambers 26a and 26b are interconnected by a passage 32. This passage 32 is controlled by a valve member 34 which is connected to a control rod 36. The cylinder 24 is connected to a link member 38 which is pivotally connected to the back rest member 16 by a pivot pin 40. The link member 38 is provided with a slot 42 which receives an eyelet 44 fixed to the cylinder 24.
The eyelet 44 is secured in the slot 42 by a clamping sleeve 46 passing through aligned bores of the link member 38 and the eyelet 44.
The lefthand end of the piston rod 28 is connected with the seat support member 10 by a pivotal joint unit 48. The pivotal joint unit 48 comprises a bolt member 50 having a middle portion 52 and two end pc;tions 54. The end portions 54 are substantially cylindrical and have diametrically opposed key surfaces 56. The middle portion 52 of the bolt member 50 is provided with a socket bore 58 receiving the outer end of the piston rod 28. The piston rod 28 is secured within the socket bore 58 by thread means.
The axial relative position of the piston rod 28 and the middle portion 52 of the bolt member 50 is defined by a clamp ring 60 engaging a circumferential groove of the piston rod 28 and abutting an abutment face of the socket bore 58. So the outer snd of the control rod 36 is always exactly positioned with respect to the bolt member 50. A securing nut 62 is threaded to the piston rod 28 and engages the bolt member 50.
A U-shaped bolt receiving member 64 is fixed to the seat support member 10.
In the side plates of the U-shaped bolt receiving member 64, there are provided bores 66 having a radially outwardly directed mouth 68 (Figure 4).
The bolt member 50 can be mounted in the bolt receiving member 64 by radially inserting the end portions 54 into the bores 66 through the respective mouth 68, when the key surfaces 56 are held parallel to the direction of the mouth. This corresponds to the position of the piston rod 28 and the bolt member 50 as indicated in dotted lines in Figure 1.
After pivoting the gas spring from the dotted illustrated position in Figure 1 into the operating position as shown in full line in Figure 1,the end portions 54 of the bolt member 50 cannot further escape from the bores 66 due to the mouth 68 having a width smaller than the diameter of the end portions 54.
The pivotal connection between the cylinder 24 and the back rest member 16 is established after the pivotal connection of the piston rod 28 with the seat support member 10 has been established. The link member 38 is pre-assembled with the back rest member 16. It is assumed that on assembling of the chair the piston rod 28 is fully inserted into the cylinder 24. So the eyelet 44 can be inserted into the slot 42 of the link member 38 and the clamping sleeve 46 can be inserted.
It is to be noted that the piston rod 28 can be pivoted through an angle of more than 90" about the axis of the bolt member 50 without a risk of the end portion 54 escaping from the respective bores 66.
In Figure 5 there is shown a second embodiment of the pivotal joint unit with a bolt member 150 and a bolt receiving member 164. The bolt member 150 extends between the side plates 164a of the bolt receiving member 164. The bolt member 150 is pivotally mounted in the side plates 164a by bearing pins 170 fixed in the side plates 164a by thread means 164b and entering into axial bores 172 of the bolt member 150. This embodiment is less preferred, because the bearing pins 170 must be mounted by screwing. It is readily understandable, however, that the bearing pins 170 could also be pressfitted or otherwise fixed in the side plates 164a.
In the embodiments of Figures 6,7 and 8, a further embodiment is shown, in which a bolt member 274 carried by a bolt support member 276 is fixed to the seat support member 10 as shown in Figure 1. A bolt receiving member 278 is connected to the outer end of the piston rod 228. The outer end of the control
rod 236 is housed within a cavity 280 of the bolt
receiving member 278. The bolt receiving member 278 is provided with a cylindrical bore 282 which is open through a mouth 284. In assembling, the
hook-shaped bolt receiving member 278 can simply
be hooked over the bolt member 274. For securing the bolt receiving member 278 against loss of engagement with the bolt member 274, a securing
element 286 is provided.The securing element 286
comprises a slit clamping sleeve 288 clamped onto the neck portion 278a of the bolt receiving member
278. This clamping sleeve 286 carries on both sides of the bolt receiving member 278, as shown in Figure 7, a pair of fork arms 290a, 290b, these fork arms
290a, 290b being provided with recesses 290c, 290d.
These recesses 290c, 290d are in engagement with
extensions 274a of the bolt member 274 extending
beyond the bolt receiving member 278, as seen in
Figure 7.
Although the invention has been described and
illustrated herein by reference to specific embodimentsthereof, it will be understood that various modifications and variations of such embodiments may be made without departing from the inventive concepts embodied therein.
All such modifications and variations, therefore, are intended to be encompassed within the spirit and scope of the appended claims.
