Abstract
Abstract A load cell weighing apparatus includes a load cell having one end secured to a base, a receiving member secured to the other end of the load cell, and a load supporting member movable with respect to the base and receiving member, wherein a load to be weighed is applied to the load supporting member. Springs are provided between the load supporting member and receiving member for transmitting the load applied to the load supporting member to the receiving member, and a stopper cooperates with the base to define the full stroke of movement of the load supporting member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
152 words
A load cell weighing apparatus, comprising: a base; a load cell having one end secured to said base; a receiving member secured to the other end of said cell; a load supporting member movable with respect to said base and said receiving member, wherein a load to be weighed is applied to the load supporting member: elastically deforming means provided between and directly contacting said load supporting member and said receiving member for directly transmitting the load applied to said load supporting member to said receiving member; and a stopper formed by an elongated portion secured to said load supporting member and having its direction of elongation extending from said load supporting member toward said base, wherein said stopper coooperates with said base to define a full stroke of movement of said load supporting member and avoids destructive deformation of said load cell by the load applied to said load supporting member.
Claim 2
Dependent Claim
152 words
A load cell weighing apparatus, comprising: a base; a load cell having one end secured to said base; a receiving member secured to the other end of said cell; a load supporting member movable with respect to said base and said receiving member, wherein a load to be weighed is applied to the load supporting member: elastically deforming means provided between and directly contacting said load supporting member and said receiving member for directly transmitting the load applied to said load supporting member to said receiving member; and a stopper formed by an elongated portion secured to said load supporting member and having its direction of elongation extending from said load supporting member toward said base, wherein said stopper coooperates with said base to define a full stroke of movement of said load supporting member and avoids destructive deformation of said load cell by the load applied to said load supporting member.
Claim 3
Dependent Claim
39 words
The load cell weighing apparatus according to claim 1, wherein said stopper includes load supporting member stroke adjusting means provided on one of said base and said load supporting member for adjusting the stroke of said load supporting member.
Claim 4
Dependent Claim
49 words
The load cell weighing apparatus according to claim 2, wherein: said load supporting member stroke adjusting means includes a length adjusting screw threadably engaging said elongate extending portion so as to be displaceable relative to said elongate extending portion in the direction of movement of said load supporting member.
Claim 5
Dependent Claim
65 words
The load cell weighing apparatus according to claim 3, wherein: said receiving member has a hole into which said elongate extending portion of said stopper is freely received; the moving direction of said elongate extending portion and said load supporting member together being guided by said hole; and said elastically deforming means is a coil spring wound around said elongate extending portion of said stopper.
Claim 6
Dependent Claim
46 words
The load cell weighing apparatus according to claim 2, wherein said load supporting member stroke adjusting means includes a length adjusting screw threadably engaged in said base so as to be displaceable relative to said base in the direction of movement of said load supporting member.
Claim 7
Dependent Claim
90 words
The load cell weighing apparatus according to claim 1, wherein: said receiving member has a hole into which said elongate extending portion of said stopper is freely received, the moving direction of said elongate extending portion and said load supporting member together being guided by said hole; and said elastically deforming means is a coil spring wound around said elongate extending portion of said stopper to abut said load supporting member at one end of said spring and to abut said receiving member at the other end of said spring.
Claim 8
Dependent Claim
152 words
A load cell weighing apparatus, comprising: a base; a load cell having one end secured to said base; a receiving member secured to the other end of said load cell; a load supporting member movable with respect to said base and said receiving member, wherein a load to be weighed is applied to the load supporting member; elastically deforming means provided between said load supporting member and said receiving member for transmitting the load applied to said load supporting member to said receiving member; a casing provided on said base and extending toward said load supporting member to cover at least said load cell and said receiving member; and a stopper provided on said casing at a position facing said load supporting member, to define a full stroke of movement of said load supporting member and avoid destructive deformation of said load cell by the load applied to said load supporting member.
Claim 9
Dependent Claim
152 words
A load cell weighing apparatus, comprising: a base; a load cell having one end secured to said base; a receiving member secured to the other end of said load cell; a load supporting member movable with respect to said base and said receiving member, wherein a load to be weighed is applied to the load supporting member; elastically deforming means provided between said load supporting member and said receiving member for transmitting the load applied to said load supporting member to said receiving member; a casing provided on said base and extending toward said load supporting member to cover at least said load cell and said receiving member; and a stopper provided on said casing at a position facing said load supporting member, to define a full stroke of movement of said load supporting member and avoid destructive deformation of said load cell by the load applied to said load supporting member.
Claim 10
Dependent Claim
30 words
The load cell weighing apparatus according to claim 7, wherein said stopper includes load supporting member stroke adjusting means for adjusting the stroke of movement of said load supporting member.
Claim 11
Dependent Claim
46 words
The load cell weighing apparatus according to claim 8, wherein said load supporting member stroke adjusting means includes a length adjusting screw threadably engaged in said casing so as to be displaceable relative to said casing in the direction of movement of said load supporting member.
